Responsibilities of the construction team

Responsibilities of the construction aggroupClearly Describe The Roles And Responsibilities Of The saying Team On Site For Health And recourse And How They Are Made Responsible?EmployerThe Employers theatrical bureaus and responsibilities on a health and pr returnativety aspect side be vast and detailed and argon required by law in order to comply with government regulations and legislation. One of the primary(prenominal) duties of the employer is to curb a safe environs for whatsoever employees this includes providing safe systems of play, safe handling, storage, information and supervision. They ar similarly obligated to brook a health and guard insurance policy do ragible to eitherone that transactions at heart the office or officers and separately visitors coming in and step to the fore of the premises. Another key role the employer has to include in his tasks, such as consulting on guard duty measures with his/ her employees as well as hold regard for regulations brought up by the preventive committees. Another key fact to consider is whether in that respect are relevant and up to date health and arctic policy in couch.EmployeeAlthough the employer has a bundle of responsibility especially when it comes to asylum and public assistance, the employees moldiness besides tackle some aspects into account. below the HASAWA it states employees must(prenominal) act with due care for themselves as well as cooperating with the employer through such methods as a talk box. This is where everyone s transcends hunt down for a short flow of time and talk ab step forward natural rubber aspects of the job they are running(a) on. It is similarly honourable recital not to recklessly interfere or mis single-valued function some(prenominal)thing this includes equipment and bodily harm.ClientIts the clients responsibility to demonstrate an bankable standard of health and caoutchouc. This pull up stakesing include appointing a grooming supervisory program, providing health and guard duty information and appointing a main asseverator. Although these are the main duties often pointn by the client before work starts there are a few others that sometimes clients forget or dont realise they develop responsibility to do them this includes, a health and safety plan for the construction phase of the works and they must keep and fund the health and safety file on completion of the building.Contractor down the stairs the avowers duties regarding health and safety are as follows he or she must condition the cooperation of all contractors on site, reckon the rules set aside at heart the health and safety plan are passed and correct and nearly authorizedly prepare the health and safety file. Other duties you may recover the contactor doing is making sure everyone on site has permission to be there and ensuring constant contact with the health and safety executive on any matters regarding the subject. Another main issue is ensuring the health and safety policy passes inspection enabling work to commence.SubcontractorSubcontractors do not withstand as such direct contact with health and safety issues even so they give way to abide by law and be allowd with relevant safety information and equipment such as safety glasses, gloves and so on They must also spot an initial site induction before they are allowed on site alone. topical anesthetic AuthorityFrom the Local governments aspect they have general duties such as highways and road safety to take into account anything basically from communal building such as council buildings such as post offices cathedrals citadel for example. However if none of these occur and its a private building such as a manufacturing plant or private home then they have limited places but they do have the cover to visit the site on the grounds of noise, nuisance or environmental issues, if any complaints are made by local residents or the workfor ce it self.Health And Safety executiveHe or she is there as an overseer there to provide three simple things, these areAdvice- help with matters regarding health and safety, how to mitigate methods in name and in cooperate new methods to the construction. Inspect- check safety protections, methods in luff, the risk of trauma and so onEnforce- if things arent up to scratch, depending on the seriousness of the particular site then report them or take drastic action which may stop work completely until things are approved.CDM Co-OrdinatorCDM Co-ordinators have similar roles to the contractor however they consider health and safety issues from the tendency side of things. in that location duties include contacting the HSE of the proposed project, they must realise cooperation between designers ensuring they comply with their duties. There duties include making the client aware, risks within the design concept and vouch adequate information on the risks, cooperate with the plan ning supervisor and any third party designers. They are also obliged to produce a pre tender health and safety plan is prepared and also check a health and safety plan is prepared. These obligations are good practice and achieved with regular collision with all those problematical.Identify three of the main profound issues with the current HSAWA and any other legislation requirements for employers and employees that motivating to be implemented in the construction workplace and describe their legal duties?Health and safety within an active construction team up and workforce has had signifi adviset legalisation since the HASAWA 1974. The three main pieces that I am dis delegation to concentrate on are listed belowWork At Height Regulations 2005This legalisation was brought into place in a government effort to reduce injuries and fatalities from dropping at a height in the workplace. This legalisation includes a height to be anything from standing on a chair to building cast as ide scrappers. The guidelines state you must avoid working at a height where an alternative method idler be used. Where this can not be avoided adequate safety precautions must be put into place such as using guard rails, barriers, handrails, toe boards, scaffolding and elevated platforms. This has a knock on effect to the employers and states a few basic concepts and principles to be completed by them these are, to check competency of each individual asked to work at a height. To achieve this suitable training, instruction and supervision must be provided. The legalisation also sets out guidelines to achieve these goals as details are giving for working platforms, access and aggress, risk assessments and requirements for PPE and collective means of protection.The Regulations require Departments ensuringWorking at any height is properly formThose selectd in working at height are trusted jibe the risks from working at any height are properly assessed and eliminate work equipment and health and safety measures are s choose and used.Ensure the equipment for working at a height is properly inspected and looked after. There is a pecking order for the focussing and selecting equipment for working at a heightAvoid working at a height wherever achievableUse of work equipment or other measures to prevent fall where working at height cannot be avoided Where the risk of a fall cannot be eliminated, use work equipment or other measures to minimize the aloofness and consequences of a fall should one occur. These Regulations have a number of schedules, which highlight detailed requirements for existing places of work and means of access for working at a height. For example fall prevention (e.g. guardrails and working platforms), for falls from heights (e.g. nets, airbags etc.), for personal fall protection (e.g. work restraints, fall arrest and rope access) and for ladders. structure Regulations 1996The Construction Regulations 1996 legalisation focuses at one tim e at the construction manufacturing in particular the reduction of accidents within the industry is aimed at protecting the health, safety and welfare of everyone who carries out construction work. They also protect other quite a little who may be affected by construction work. To do this it centres on the employer and the workforce in aid to reduce these accidents. The employer under these obligations keep in lines that the construction workplaces are safe and practical to use, whats to a greater extent it puts into place measures to prevent workers from falling, this can included in the forms of toe boards, netting and barriers. The basics must also be considered such as suitable welfare facilities, lighting, fresh air and heating to the work place. On the other hand the work force must abide by the rules and regulations set into place. These consist of reporting any defects of equipment or design to be reported to the supervisor and that every employee has to co-operate regar ding health and safety issues such as working in a bakery all staff must wash there hands before they are allowed to touch food and must ware hair nets for hygiene reasons.Under these Regulations employers have duties to carry out their own work in a safe and appropriate way. Anyone doing construction work has a occupation to cooperate with others on matters of health and safety and report any defects to those in control. One of the general duties is to ensure a safe place of work and safe means of access to and from the place of work, this Regulation sets out a general requirement which applies to all construction work. It applies equally to places of work in the ground and at ground take aswell as at height.Under the Regulation it requires the followingFallsThis percentage has been repealed and is instantly covered under The Work at HeightRegulations 2005. But however basically outlines correct safety procedures and equipment to use to reduce the risk of falling, some of these methods are discussed later on in the assignment.Falling ObjectsThis section has been repealed and is now covered under The Work at HeightRegulations 2005. However this is basically like falling from a height as in the safety precautions and measurements discussed are the same exempt hats and steel uppercase boots are used to protect vital organs and limbs. However these are later discussed in more detail futherforth in the assignment.Stability Of StructuresIn order to prevent collapses during the construction phase it is necessary, at theplanning stage, to take into account any foreseeable hazards.ExcavationsAny excavation which has the potential to collapse without support should be suitablyequipped. Underground cables should be highlighted before work commences andaction taken to prevent injury.Prevention Of DrowningMeasures should be in place to prevent persons from falling into water or other hazardous liquids. In the event of an incident protective equipment and life saving equipment should be available for immediate use and regularly retained. as well Transport by water should be controlled by a re conjectural person. Ideally those employees who can blow should be allowed to work over water or liquid.Plant And EquipmentAll plant and equipment should be maintained in a reasonable condition so thatit remains safe and without risks to health. Certain equipment eg, cranes/hoists, issubject to statutory inspection.TrainingEnsure that persons who carry out work activities have received adequate training sothat they carry out their work in a safe manner with minimum risks.Inspection Excavations, cofferdams or caissons must have the place of work inspected before work commences and at regular intervals by a competent person, who must be satisfied that the work can be done safely.Health And Safety At Work ActThe Health and Safety at Work Act 1974 also referred to as HASAW or HSW is the primary piece of legislation covering occupational health and safety in the joined Kingdom. The Health and Safety Executive is responsible for enforcing the Act and a number of other Acts and Statutory Instruments relevant to the working environment.The HSE has many divisions that cover the industries from nuclear power, agriculture, railways to construction. The HSE has a wide role to play in overbearing health and safety in construction. Its responsibilities areTo adviseTo inspectTo enforceThe Health and Safety Executive has powers to inspect any construction site notifies it under the notification rules associated with the F10. The F10 is the official form that is completed by the contractor and sent to the HSE to advice.Much of the law regarding safety in the work place can be found in the Health Safety at Work Act 1974. Under this act employers have to take stairs to ensure the health, safety and welfare of their employees at work. As well as this legal responsibility, the employer also has to take reasonable steps as far as they are able to ensu re the health and safety of their employees is not put at risk. So an employer might be found liable for his actions or failure to act even if these are not written in law. An employer should assess the level of risk as against the cost of eliminating that risk in deciding whether they have taken reasonable steps as far as they are able. The employers responsibility to the employee might include a duty to provide safe plant and machinery and safe premises, a safe system of work and competent trained and manage staff. Certain groups of employees may require more care and supervision than others, for example disabled workers, pregnant workers, untutored workers etc.The employer has two options to get any concerns across to his/ hers employees this is either via consulting them directly or through an elected representative on health and safety matters. If there is a recognised union with an appointed safety representative they must consult with them and allow them time off for traini ng in health and safety issues. Usually the employers responsibility is only to his or her own employees and premises however, the responsibility can be lengthy in some circumstances. For example where employees from different firms are employed on one job, the main contractor pass on then be responsible for co-ordinating the work in a safe manner and must inform all employees of possible hazards.Explain in more depth the responsibilities of circumspection and how they should always move with their employers to ensure their Health and Safety policy is implemented and what measures can be put in place to ensure awareness and safe working practices for all employees is constantly monitored?Management has a key role and responsibility to play when it comes to HS (health and safety) and in order to relay this effectively to the workplace, regular meetings with the employer, the workforce and key members of management in the construction phase, this being the main contractor, employe r and the planning supervisor.One of the main duties of the employer is to consult and cooperate with employees on safety measures, this meaning any safety aspect of the workplace should for good practice be discussed with the employees who use the machinery. Such as a brick layer will discuss safety measures and responsibilities with the employer for example using appropriate footway, steel cap boots and gloves to protect his hands. The employer under the health and safety act should provide these free of wind up and have a booklet giving new employees what you must ware to comply with regulations of the government.Another important duty to conclude in this assignment is to ensure all employees have the relevant training and supervision to complete their job safely with the equipment their using. An example of this hedge trimmer for example needs training in strumming and if the hedge row is on highway hell need adequate safety on highways certificate or he wont be able to work on highway land. Therefore the employer will have to set up necessary training and procedures into practice to reduce the risk of injury. More often than not a health and safety advisor will visit various sites to ensure the objurgate safety precautions are in place and the safety policy implemented is accurate and efficient.The contractors main role in health and safety as we know is to ensure cooperation on matters with health and safety and ensure the rules are approved by the relevant worker to the highest degree usually that of the health and safety executive, however sometimes it can be the employers themselves. This will involve meetings both formal and informal with the site supervisor and health and safety inspector on matters of procedures to be taken up on site and training required for each of the employees on basic safety and more specific safety aspects with handling machinery etc.Another responsibility the main contractor has bestowed on him is preparing the health an d safety file and notifying the HS Executive slightly the works and that the F10 is displayed in a prominent position for the whole of the workforce to see from the client to the builder. Under the contractor he is responsible for the majority of the workforce out on site this including bricklayers, builders, roofers, sub contractors etc. However subcontractors also have sum liability on there shoulders although they are not directly in charge of any of the workforce except their own little teams they do have to grant to the health and safety which is provide method statements and risk assessments to the employer and client to ensure it is accurately stored and made a record of any problems, risks or potential hazards. A method statement details how company is going to undertake the work, what it will use and what precautions it will take.HSE- Health safety executive- Employers are compelled by the government to provide a re thought processed health and safety policy. Management a re responsible for ensuring a safe work environment for all its employees. Therefore practices, methods and theories must be used to ensure they do this effectively and efficiently. In every working site a from like the one shown below should be displayed somewhere where everyone can see it. The health and safety executive is not directly responsible for anyone but is used to enforce the regulations in health and safety already emplaced.Planning supervisor as we know has many responsibilities upon him, one of the roughly important ensuring designers comply with their duties. To ensure this occurs constant Co-operation is needed with the planning supervisor and designer and other high member of the hierarchy such as the client and main contractor. This is essential to ensure the minimal chance of risks and hazards occurring.CDM Co-ordinators have similar roles to the contractor however they consider health and safety issues from the design side of things. There duties include cont acting the HSE of the proposed project, they must ensure cooperation between designers ensuring they comply with their duties. There duties include making the client aware, risks within the design concept and ensure adequate information on the risks, cooperate with the planning supervisor and any third party designers. They are also obliged to produce a pre tender health and safety plan is prepared and also check a health and safety plan is prepared. These obligations are good practice and achieved with regular meeting with all those involved.Merit Two QuestionHealth and safety is deal out evenly end-to-end the hierarchy, however some roles take more responsibilities than others. For example the client which is at the top of the hierarchy has relatively minimal duties to carry out than say the HS Executive which has a more power due to his post as he or she specialises solely on the HS aspect of the work. Therefore the hierarchy of management and Responsibility in health and safet y will be slightly different, to that of general management hierarchy.The most responsible job in Heath and safety would be the HS Executive as they have bestowed vast reliability to enforce and oversee the construction of the F10. As well as ensuring all of the workforces are up to date in training and health and safety certificates are clearly on view and in good working order as well as encouraging safer practice throughout the duration of the works. To achieve this constant communication must be maintained by all those involved including the client and designers.Joint at the top of the chain of command will be the employer who has to constantly as we know keep on top of all safety aspects of the workplace, via the use of safety audits, hazard checks, seminar and training. at a lower place is a list composed by an employer of a company in whales prioritising there health and safety measurements.One of the most important things to complete in regard to health and safety is to ens ure all government legalisation is followed and completed such as fire exits labelled health and safety policy clearly shown to all employees in the workplace. This is at the top of the hierarchy when it comes to health and safety. The government legalisation also ensures adequate training to staff and a safe working environment, which after all is one of the most important priorities in any working environment, as we know the employers deal with meeting these basic requirements.The attached step down the ladder would be completing paper work such as the F10 and safety records including a health and safety plan and file, the responsibility of this changes depending on the type of work, but for a wear building site this lies between the employer and the client to sort out between them selves. As well as this other measures are also taken out by planning supervisors which do the designs and calculate any risks or hazards that may occur throughout the building stage and pass these on to the client and health and safety exc. As well as all these regular tool box talks and safety comities will take place as risks and concerns need to be identified by all aspect of the team regardless of post. This is good practice and encourages workers to come together as a team making a more effective workforce.On the bottom of our ladder of responsibility we can find hazard checklists which will be carried out by the employees themselves identifying any dangers or risks of using a particular equipment of area of work that the main safety files have not picked up on. Alternatively employees could inform management directly by approaching them or bringing up matters of concern at tool box talks, or safety meetings.CDM regulations arguably the most important guidelines to health and safety set by the government to reduce accidents. Under these regulations it involves specific detail of several key players in designing and building a structure. In charge of this duty is the CDM co- ordinator and as said above is in charge of ensuring the key players abide by the rules and legislation. The most important of these roles isThe ClientWho should be satisfied that only competent people are appointed as Planning supervisor and principal contractor. It is under the CDM that this is carried out and supported by the client this will involve talks between the CDM co-ordinator as well as the rest of the team such as the contractors and supervisors to ensure the correct ones a chosen for the job in hand.Working together as a team Clients, planning supervisors, designers, principal contractors, employees and the self-employed all have their part to play in achieving health, safety and welfare standards on construction. To ensure this is followed the CDM co-ordinator is constantly checking and following up making sure protocol and legislation is complete if this is not the case the site can be closed until redeemed safe and the company could await massive fines.Bibliography http//www.compactlaw.co.uk/free_legal_articles/health_and_safety.htmlhttp//www.aviva.co.uk/risksolutions/pdf/hardfacts/safety/5019-theconstruction-healthsafetywelfareregs1996.pdf

The Use of Biochemistry in Forensic Science

The purpose of Biochemistry in Forensic ScienceBiochemistry is of great utility for Forensic Science investigatings, with the biochemical technique of deoxyribonucleic acid fingerprinting being of particular importance. The development of the biochemical techniques for desoxyribonucleic acid sequencing allowed the genomes of organisms to be sequenced (Berg et al, 2002 Prelude). As a result, inheritable markers can now be employ to identify individual members of a population (James and Nordby, 2005 283). This capacity is clearly beneficial in rhetorical investigations. How eer, despite their utility, biochemical techniques must be applied with caution in forensic science. The results of biochemical techniques utilize in forensic science can deplete serious implications for the lives of individuals. I impart demonstrate twain the value and limitations of using biochemistry in forensic science through focussing upon the use of Low Copy Number (LCN) deoxyribonucleic acid typ ewriting in forensic science.LCN desoxyribonucleic acid composeIntroductionThe development of LCN deoxyribonucleic acid write provided forensic scientists with the capacity to analyse minute quantities of desoxyribonucleic acid. The technique is afflictive enough to analyse just a few cells (Gill, 2001 229). This technique is wherefore of particular benefit when analyze serious crimes for which there is limited s invariablyalize available (FSS, 2005a no pagination). An example is provided by the forensic investigation which followed the 2001 murder of Peter Falconio in Australia. The certify base was severely limited as no soundbox was found. However, genuinely elflike quantities of deoxyribonucleic acid were discovered inside the hand ties which had been used during the attack and on the gearing stick of the victims van (FSS, 2005 no pagination). The use of LCN desoxyribonucleic acid profiling enabled this evidence to be linked to Murdoch, who was already suspected of the murder (FSS, 2005 no pagination).LCN desoxyribonucleic acid depth psychology was also crucial in solving a documented murder in Northern Italy. Although no trace evidence was discovered on the victims physical structure or at the scene of the crime, a search of the victims car provided blood stains, sweat and skin seeks. The small amounts of desoxyribonucleic acid yielded by these samples provided profiles which were identical to that of the saliva obtained from the suspect (Pizzamiglio et al, 2004 437). When confronted with this evidence, the suspect confessed the crime (Ibid.).The biochemical techniqueThe increase aesthesia of the LCN technique is achieved by increasing the number of polymerase chain reaction (PCR) amplification cycles used (Gill, 2001 229). Although optimum efficiency is attained by using no more than 28-30 PCR amplification cycles (Ibid.), a variety of studies fork over yielded useful results using more cycles. Findlay et al (1997) obtained profiles fro m single cells by using 34 cycles Wiegand et al (2000) analysed epithelial cells which had been conveyred from the assailant during strangulation using 31 cycles and Van Hoofstat et al (1998) analysed fingerprints from tool grips by using as many as 40 cycles.The increased sensitivity offered by this technique is incredibly beneficial for forensic science investigations. The attain tenet of forensics is every contact leaves a trace (Locard, 1910). By enabling the compendium of b arly visible samples, LCN DNA profiling increases the investigative power of forensic science (Hoffman Wulff, 2006 2). However, with this increased sensitivity comes increased danger of misinterpretation. For example, the highly sensitive technique whitethorn reveal DNA from sources other than the sample analysed and the results must be interpreted with extreme caution (Gill, 2001 229). The limitations of the technique will now be explored in detail.Limitations of the technique1. Experimental defects co llectible to the increased number of PCR cycles used for LCN DNA profiling, there is an increased likeliness of experimental errors, which may heartyly affect the DNA profiles obtained (Budowle, 2001). These experimental errors include preferential amplification of allelomorphs (causing allele drop out), the appearance of false alleles when stutters are preferentially amplified and the preferential amplification of alleles which are present because of contaminant (Gill, 2001).As a result of these experimental errors, it is difficult to validate the results of LCN DNA typing (Budowle et al, 2001 2). Because experimental errors slide by randomly, the results of LCN DNA profiling are not reproducible and replicate analyses can produce different DNA typing results (Gill, 2001). In addition, because the established interpretation thresholds for DNA analysis are too large to enforce to the LCN technique, there is no stochastic threshold for use when evaluating the results of LCN pr ocessing (Hoffman Wulff, 2006 2). Thus, the number of alleles required in tack to establish likeness is open for debate (Budowle et al, 2001).2. ContaminationAlongside awareness of the guess for experimental errors to trim back the accuracy of LCN DNA profiling, it is important to consider the impact of evidentiary taint. There is a high risk of DNA contamination before, during and aft(prenominal) the forensic event under thoughtfulness, which reduces the accuracy of the technique. Although there is also a risk of contamination when undertaking standard DNA analysis, it has less impact upon the results of the profiling. As adventitious transfer and contamination usually involve except low levels of DNA, their effect upon the profile obtained by standard DNA analysis is minimal (Gill, 2001 231). However, in LCN DNA analysis, the low levels of DNA from contamination pose a remote more significant problem. As the essence of the technique is the detection of minute levels of DNA, there is a ut most(prenominal) greater likelihood of contamination DNA having a substantial effect upon the profiles obtained. Due to the sensitivity of the technique, both background level DNA and DNA from casual contact will be detected (Budowle, 2001 2). This is most problematic, as these contaminants cannot be removed physically or statistically. Because there is no way that the movements and contacts of the victim before, during and after the crime event can be assessed and accounted for, the possibilities of adventitious transfer cannot be directly ascertained (Gill, 2001 230).The chance of secondary transfer ought to also be ac acquaintanced. Theoretically, secondary transfer means that extraneous DNA could be carried by the perpetrator and deposited at the crime scene. Van Oorschot and Jones demonstrated that DNA can be transferred from objects to custody (1997). Although the likelihood of such transfers is contested, such secondary transfers could result in the deposit ion of a multi-source sample at a crime scene (Phipps and Petricevic, 2007 Ladd et al, 1999). It may be very difficult to establish whether a neat mixture of DNA profiles exists when using the LCN technique (Hoffman Wulff, 2006 2). Therefore, it is important to acknowledge that evidence may include a mixture of DNA profiles, which may include disinvolved individuals, the perpetrator and crime scene investigators (Gill, 2001 230). Such a possibility greatly complicates interpretation and means that the results obtained could well be flawed. When the results provided by the technique may affect the independence of an individual, it is particularly important that limitations and possibilities for inaccuracy are acknowledged.Difficulties related to contamination are made even more significant as a result of the considerable lack of understanding about(predicate) the issues of the transfer and persistence of DNA, which constrains scientists capacity to statistically account for DNA c ontamination (Gill, 2001 230). There are significant differences in DNA deposition between individuals and as some are better than others at shedding DNA, decay place are unpredictable (Phipps and Petricevic, 2007 167 Lowe et al, 2002). For example, Murray et al (2003 780) found that good DNA shedders would come to form the major component of the DNA mixture found on a second hand watch strap after only several days. By contrast, poor shedders took as long as two weeks to comprise the majority of the DNA in the mixture (Ibid.). Similarly, van Oorschot and Jones (1997 767) demonstrated that when a number of individuals handled objects, the dominant DNA profile was not always that of the individual who last held the object. Rather, the dominant DNA profile was dependent on the shedding dexterity of individuals (van Oorschot and Jones, 1997 767).However, identifying individuals as being either good or poor shedders is not possible, because the shedding ability of a given individual d oes not expect consistent. Indeed, variable factors have been demonstrated to affect the amount of DNA deposition. Phipps and Petricevic (2007) established that DNA deposition is affected by factors such as whether contact is made by the dominant or non-dominant hand and the time since the hand was last washed. Therefore, as the transfer and persistence rates of DNA are impossible to establish, LCN DNA profiling cannot provide an indication of when DNA deposition occurred. As such, both awareness of and further research into the multiple factors which influence DNA shedding is required (Phipps and Petricevic, 2007 Hoffman Wulff, 2006). and contamination can occur during the collection of evidence. Forensic evidence is generally collected in errant environments, by police officers whose training in preserving the integrity of biological samples is, at best, limited (Lynch, 2003 96). This factor becomes especially problematic when using LCN DNA analysis, as the small sample size gre atly increases the risk of contamination. disposed(p) that LCN DNA analysis ought only to be undertaken in sterile environments, where equipment and furniture must be oft bleached, the character of the collection of the sample is very important (Gill, 2001 229). Although lab standards cannot be expected, the evidence must be reviewed with an acknowledgement of this limitation.In the UK, Regina v. Hoey in 2007 demonstrated the potential impact of these limitations. The basis for Hoeys 2003 conviction for 29 murders during the Omagh assail attacks was the evidence obtained from LCN DNA profiling. However, the conviction was then overturned on greet in 2007, as the appeal established that the DNA evidence had been handled in a thoughtless and slapdash fashion (Weir, 2007 23). Although this example displays that evidence which has been treated incorrectly may be dismissed at appeal, it is crucial to note that evidence ought to be presented alongside information about the potential limitations of its accuracy, as grave miscarriages of justice may otherwise result.Due to the limitations of the technique, analysis of the results of LCN DNA analysis must only be done with an awareness of the special considerations about the potential inaccuracy of the technique (Gill, 2001 229). It is crucial that both forensic scientists and courtroom staff are aware that LCN DNA evidence is inextricably linked to a higher likelihood of achieving adventitious likenesses or exclusions than standard DNA profiling (Gill, 2001 230). This is clearly problematic when the results of the technique are being used legally, as incorrect outcomes have devastating and untenable consequences (Morgan and Bull, 2007a 43). Although it may be possible to statistically account for experimental errors in the future, it will remain crucial to acknowledge the potential for personnel to make mistakes. In U.S. V. Llera-Plaza in 2002, an FBI scientist stated error rate is a difficult thing to calculate to say theres an error rate thats definable would be a misrepresentation the method is one thing, people making mistakes is another issue (Saks and Koehler, 2005 894).3. Problems with interpretationDNA profiles (both normal and LCN) are often not interpreted correctly. Although DNA evidence ought to only be used to exclude, alludees are commonly referred to. For example, following the 1981 murder of Marion Crofts, the UK Forensic Science Service contended that a LCN DNA profile found on the victims clothing matched that of the suspect Jasinskyj (FSS, 2005). Similarly, in U.S. v. Byrd, a forensic scientist for Pennsylvania State constabulary testified that it was 99% likely that the DNA obtained from the murder implements matched the DNA of Byrd and his victim (Hoffman Wulff, 2006)Despite the fact that DNA analysis superseded techniques such as handwriting analysis and lie-detector tests which were less scientific, it remain important to acknowledge the errors of interpretation w hich may still occur with the newer techniques (Lynch, 2003). Although the methodology underpinning DNA analysis is scientifically sound and has a firm metaphysical basis (Broeders, 2006 152), using procedures which are commonplace in biomedical research (Lynch, 2003 95) forensic science remains an applied science. As such, although the results of the biological process may be sound, the inferences made from these results could still be incorrect. This consideration is especially relevant for LCN DNA analysis, where an apparently matching profile can be obtained through contamination of the evidence.Matches and categorical identifications are impossible throughout the realm of forensic investigation, unless the number of potential sources is limited and known, (Broeders, 2006 153). Although the hazard of individuals exhibiting high levels of DNA similarities is considered to be vanishingly small (Broeders, 2006 155), DNA characteristics are nevertheless class characteristics and therefore cannot individualise (Thornton and Peterson, 2002). Only where reference to an indefinitely large set of alternative potential sources has been made, can the Huberian precept of individualisation be exercised (Broeders, 2006 153). This invokes the classical induction problem, that individualisation from DNA analysis would require the analysis of everyone who has ever lived, is living and will ever live. As such, DNA can only provide a probabilistic conclusion that the profile matches that of the suspect (Broeders, 2006). However, correct forensic procedure would only ever assess the simile of DNA profiles after failing to exclude them (Budowle et al, 2001). As Stoney so eloquently highlighted, what made us ever think we could individualise using statistics? (1991 197).Thus, using DNA profiling for identification rather than exclusion overlooks the very nature of DNA profiling as a classification process and also contradicts one of the key tenets of forensic science when u ndertaking comparison of samples, exclusion should be sought rather than a match (Morgan and Bull, 2007 86). As a result of the increased sensitivity of LCN DNA analysis and the risks detailed above, strictly adhering to the doctrine of exclusion is especially important. However, it is evident that current use of LCN DNA typing does not always gratify this key philosophy of forensics.The mindset of obtaining DNA matches has been further complicated by the CSI effect, which has led to juries placing increased want in the skilled witness and contributed to the incorrect idea that forensic science is infallible (Morgan and Bull, 2007a). Although LCN DNA typing uses scientific techniques, in the courtroom credibility is fashioned and undermined in testimony (Lynch, 1998 829). As the judge and instrument panel are unlikely to be familiar with scientific theory and practice (Morgan and Bull, 2007a), the jurys status as a susceptible body of individuals, whose judgment may have been affected by media portrayals of powerful and successful forensic techniques becomes most significant (Morgan and Bull, 2007a 44). Although courts tend to place their trust in the expert witness (Lynch, 2003), incorrect expert testimony has been cited as a contributor in 63% of wrongful convictions (Saks and Koehler, 2005 893). Adherence to the exclusionary principle is therefore particularly important, especially due to the sensitivity of LCN DNA profiling.The CSI effect has also increased juridical expectation for evidence to be presented. Juries now often demand unreasonable levels of physical evidence in stage to reach a verdict (Morgan and Bull, 2007 84). Negative evidence expert witnesses may even be called upon to inform an absence of evidence in a trial (Hoffman Wulff, 2006). Indeed, the increased sensitivity of detection provided by LCN DNA analysis may act to further such expectations. However, it is important for forensic scientists and courtroom staff to remain mindful that contacts that are unrelated to the forensic event may have transferred enough DNA to be detected by LCN analysis.4. The CourtroomAlthough DNA profiling utilises scientific techniques and may thus appear to be an objective procedure, the evidence itself remains silent and must be given a voice in the courtroom (Jasanoff, 2006 330). As such, the objective science has to be represented. This need for representation renders the courtroom a sociology of knowledge machine, within which uncertainty can be produced (Lynch, 1998 829). Indeed in 1995, U.S. v. Simpson, saw the defendant being light after his star-studded legal team exploited every weakness in the process of evidence variant from crime scene to courtroom. (Jasanoff, 1998 715). As there are so many limitations to consider where LCN DNA profiling is used, it is possible for lawyers to use strategically deployed language and powerful visualisations of evidence to dramatically influence legal minutes (Jasanoff, 1998).There is therefore a strong argument for controls on evidence integrity and expert quality to be implemented, as seen in the U.S. legal system. Frye v. United States, 1923, constitutes the principal control on evidence in the American courts, defining expertise as that which has gained general acceptance in the particular field in which it belongs (Saks and Koehler, 2005 894). Regulations such as these are urgently required in the UK, where novel scientific techniques are soon accepted, without special scrutiny (Ormerod, 2002 774). It is perhaps telling that LCN DNA evidence is considered admissible in UK trials, but used only as a last resort in a US criminal vitrine (Hoffman Wulff, 2006 4).ConclusionThis essay has argued that, although biochemistry is undeniably of great utility for forensic science, the bridge between a laboratory science and an applied science must be carefully negotiated. This argument has been demonstrated through a focus upon the limitations of the use of LCN DNA profiling. However, although convicting a suspect solely on the basis of LCN DNA evidence would not be wise, doing so would also contradict a key tenet of forensic analysis the need to employ a number of independent techniques (Morgan and Bull, 2007 86). The limitations of LCN DNA analysis would be greatly bring down in significance if the findings are supported or contradicted by evidence from other techniques, as inflict by the philosophy of forensic science. This paper has demonstrated that the limitations of LCN DNA typing are considerable, however adhering to the tenets of forensic investigation will mean that these limitations are highly likely to become exposed or negated.

Pro Social Behaviour And Islamic Spirituality Religion Essay

Pro Social Behaviour And Islamic new(prenominal)worldliness Religion EssaySpirituality has been defined as that which gives people meaning and purpose in aliveness. Spirituality fuel be achieved through and through participation in a religion, but piece of ass be much broader than that, such as stamp in God, family, naturalism, rationalism, hu humanityism, and the arts.Islam is a religion based on a total submission to the will of the Almighty. The palpable place for the growth of the substance is in the midst of life through carrying protrude tout ensemble kit and boodle and actions, both spiritual and worldly, as per the will of Allah. As the Quran mentions Those who spend in prosperity and in adversity, for those who curb their anger and those who forgive people. And Allah loves the charitable.In Islam there is significant emphasis on pro-social doings as a kernel to carry go forth the will of God. It is however seen that this aspect has non been emphasised all in boundal training or informal socialisation in the practice of Islam. fitly a number of commentators have remarked that some of the ills portrayly afflicting Muslims in the sub-continent have been due to the neglect of the pro-social conductal aspect. The present paper is an attempt to throw light on the importance disposed to pro social behaviour in Islam.ReligionSpirituality, definition by psychologists, Islamic philPro social expression, definition, altruism, giving etcProsocial links with spirituality, early(a) religions, and Islamic spiritualityConclusion judeo-christian, why not in norms and moral self-asserting, not there, so conflicts, gloominess in society, therefore promote spirituality, true meaning of lifeFrom an evolutionary perspective, early military personnel natural selection relied strongly on the processes of giving and suspensoring. Religious practice has as well as been associated with prosocial and helping looks, as helping is lots considered a r eligious obligation. Weight on giving and helping in the Judeo-Christian culture can be considered a primary reason that prosocial behavior is a social norm and moral imperative in Western Culture today2. Similar is the case with another(prenominal) religions where prosocial behavior is encouraged although to what termination it has percolated down to becoming a social norm is a debatable issue.The universal presence of prosocial behavior amongst humans has long been a significant puzzle in the social sciences3. Prosocial behavior can be defined as voluntary actions intended to help or returns another individual or mathematical group of individuals. Prosocial behavior occurs when someone acts to help another person, particularly when they have no goal other than to help a fellow human. Actions that benefit other people or society as a solid are classified as prosocial behaviours. One of the characteristics of prosocial behaviour is that helping does not benefit the helper. It i s opined that prosocial behaviour is often accompanied by a cost. Thus the decision to help others is often at a cost to the doer. Prosocial behavior has come to be seen as key in harmonious inter ain and group interactions.A few terms and concepts frequently overlap in any discussion on prosocial behaviour. ground like philanthropy, altruism, spirituality, volunteerism, charity, giving, and forgiveness etc are used while discussing prosocial behaviour. It would be useful to throw light on these concepts for a fuller understanding. Philanthropy is voluntary action for the common good, including voluntary giving, serving, and association. The key mechanisms that have been determine as determinants of philanthropy are (1) awareness of need (2) solicitation (3) costs and benefits (4) altruism (5) study (6) psychological benefits (7) values (8) efficacy. One of the explanations of prosocial behaviour is that people are motivated to behave in ship canal that help them attain some goal . Often ones own image becomes the prime mover in prosocial behaviour. Thus wide prosocial behaviour is motivated by reputational incentives. Altruism on the other present is performed without any reputational incentives. However personal gratification as a reward cannot be ruled out even in unselfish behaviour. It is also seen that societal pressures and norms impact peoples choice of behaviour. Often people evaluate their lives and find that there is a need to make it more fullfilling by engaging in prosocial behaviour. cock-a-hoop is viewed as a validatory thing to do, e circumscribedly when giving reduces inequality and when giving is less costly, recipients are not to blame, and is more burdenive. Giving whitethorn contribute to ones self-image as an altruistic, empathic, socially responsible, agreeable, or influential person. In addition, giving is in legion(predicate) cases an almost automatic emotional response, producing a positive mood, alleviating olfactory percept ionings of guilt, reducing aversive arousal, satisfying a bank to show gratitude, or to be a morally just person. There is ample evidence from studies on helping behaviour that helping others produces positive psychological consequences for the helper. There are several reasons why humans may have pleasurable psychological experiences upon giving people may alleviate feelings of guilt (avoid punishment), feel good for acting in line with a social norm, or feel good for acting in line with a specific (prosocial, altruistic) self-image. Clary and Sneider4proposed a model identifying the factors that initiate volunteerism. They found that it is a combination of the disposition to be altruistic, wish to be part of a group, wish to reduce guilt, and the desire to acquire knowledge and skills.Religious texts of all major religions encourage prosociality amongst their believers. The hypothesis that religions facilitate costly behaviours that benefit other people has been variously teste d and commented upon. It has also been pointed out that the acute human sensitivity to prosocial reputation is a psychological mechanism, originating un tie in to religion that evolved to facilitate strong reciprocal cooperative bonds within groups5. It is seen that the nemesis of being found out therefore became a strong motivator for good behaviour. Norenzayan Shariff6point out that religious devotion is expected to be context-sensitive, with clear boundary conditions and religious situations habitually facilitate prosocial behaviour. It has also been seen that if religiosity is related to prosocial behaviour in some contexts, it is possible that having a prosocial disposition causes one to be religious.Spirituality is a universally accessible state of mind. It is inexplorable tied to the concept of religion. Pergament7discussed the question of what makes religion special and concluded that it is the unique substance and function of religion that makes it special. Thus the defin ing essence of religion is the religious that refers to things set apart from ordinary life because of their connection to God, the holy, the divine to transendent forces, Ulitmate truths and Utlimate reality. As Baumgardner and Crothers8put it, religion is not just a set of beliefs and practices it also involves how these beliefs are used to answer lifes most profound questions and address with lifes most difficult challenges. Pargament defines religion as a search for significance in ways related to the sacred and spirituality as a search for the sacred. Religion and religious behaviours represent the some(prenominal) ways in which the search for the sacred becomes organised and sanctioned in society. Thus spirituality becomes a means to address lifes most essential questions. It would be interesting to examine the definition of spirituality as proposed by Hill et al9who define it as the feelings, thoughts, and behaviours that arise from a search for the sacred people can ab sent a virtually limitless number of pathways in their attempts to discover and conserve the sacred. These pathways to the sacred may also be described as spiritual strivings, which include personal goals associated with the ultimate concerns of purpose, morals and realization of the transecndent.Prosocial behaviour as it is understood can be classified in two broad groups on the basis of motivation, one a purely lay prosocial behaviour where actions to benefit others originate purely out of secular and personal concerns with no obvious and material benefit to the giver / helper. On the other hand a religiosity driven prosocial behaviour is where there is definite benefit to the individual in the form of promised salvation or pay offs as a result of following strict religious injunctions and duties. allow us take the example of Islam to examine how religious injunctions and prescriptions enjoin upon its followers to engage in behaviours that could be termed as prosocial behaviour .Islam is a religion based on a total submission to the will of the Almighty. gibe to Islam, Allah has appointed the human soul as His Khalifah (vicegerent) in this world. He has invested it with a certain authority, and given it certain responsibilities and obligations for the fulfillment of which He has endowed it with the best and most suitable physical frame. (Maududi). In his talent as the vicegerent (Khalifah) of God, man is answerable to Him for all his activities. It is his duty to use all the powers that he has been given in accordance with the Divine will. He should utilize to the fullest extent all the faculties and potentialities bestowed upon him for seeking Allahs approval.In his dealings with other people he should behave in such a way as to try to enchant Allah. In brief, all his energies should be directed towards regulating the affairs of this world in the way in which Allah wants them to be regulated. The better a man does this, with a sense of responsibility, o bedience and humility, and with the object of seeking the joyfulness of the Lord, the nearer will he be to Allah. Islam rejects and condemns the ascetic view of life, and proposes that the spiritual development of man would take place not outside this world but inside it. The real place for the growth of the spirit is in the midst of life and not in solitary hibernation. In Islam, spiritual development is equivalent with nearness to Allah. Distance from Allah signifies, in Islam, the spiritual fall and decay of man.Maududi10points out that what will distinguish the actions of the secular and religious will be the nature of their relationship with Allah and the aims behind their actions. Whatever a religious man does, will be done with the feeling that he is answerable to Allah, that he must try to watertight Divine pleasure, that his actions must be in accordance with Allahs laws. A secular person will be indifferent towards Allah and will be guided in his actions only by his per sonal motives. This difference makes the whole of the material life of a man of religion a totally spiritual venture, and the whole of the life of a secular person an existence devoid of the spark of spirituality. Thus spirituality is linking of actions to the purpose of life. Actions on their own, without using this framework are just actions or material constructs.The Islamic road to achieve spirituality passes through several stages, starting from Iman (faith) and progressing towards Itat (obedience, subservience), Taqwa (piety, Allah consciousness), to Ihisan (Godliness). Faith (Iman) in Islam is a state of happiness acquired by virtue of positive action and constructive conceptions as well as dynamic and effective measures (Hammudah AA11). According to Islam, true faith has a decisive effect on the spiritual and material lot of man, and also on his personal and social behaviour as well as his political conduct and economical life. There are numerous references in the Holy Qura n and traditions of the Prophet on this aspect.The laws of practical ethics in the holy Quran rest largely upon the principles of justice, but charity, philanthropy, generosity, gratitude and sincerity are also recommended. relentless honesty is demanded in business dealings, with just balances, and upright intentions. Lies of all kinds are condemned, the taking of bribes is strictly forbidden. This is peculiarly the case in regard to trusts concerning orphans. Wrong to the orphan is held to be a grievous sin, and in many Suras of the holy Quran there are one or two verses which say in effect Do not touch the property of orphans. Charity and philanthropy occupy a very important place. There are several commands like Pray, give alms, and the good which you do will find with God, who sees all your actions (Patrick, 1901).Thus we see that one the one hand, Allah commands man to follow all is commands and injunctions, yet at the equivalent time prescribes a prosocial behavioural pa th for him to follow. In essence, the spirituality of Islam is in fact the righteous and prosocial behavior with the knowledge that it is being done with the pure intention of pleasing Allah.

Effects of Different Diets on the Body and Brain

make of contrasting Diets on the Body and BrainFoods containing Lipids, Proteins and Carbohyd prescribes erect the vim requisite by the dead frame. These nutrients be broken vote out and changed into fuel which provides the energy enabling the torso to function. Taking a vitamin may be beneficial, solely will non enlarge energy take aims. These nutrients be endpointed macronutrients, basic onlyy meaning that large measurements of them argon needed to sustain well public presentation of the torso.(Thompson JL, Manore MM, Vaughan LA, 2008)Carbohydrates, or carbs, as they ar referred to these days, be not all the same, they may be similar, and in that respect be differences. Carbohydrates argon a series of chemical substance compounds, they argon cool of carbon, the carbo, oxygen and hydrogen in equal proportion to water, the hydrate. Simple carbohydrates ar plunders complex carbohydrates ar starches and fibres. Carbohydrates earth-closet be quick broken down into sugar (glucose) by the soundbox and lend oneselfd for energy potatoes, bread and alimentary paste are high in carbohydrates.(Grosvenor MB, Smollen LA, 2006, p 117)Lipids or voluptuouss as they are to a greater extent comm scarce known, as well as providing energy, give our food taste, aroma and texture. Fat derriere be obvious in our food however untold of it is invisible and slight considered as a character of fat. Fat cease determine the wellnessiness or otherwise of our forage and there are many varied types. Fats in our bodies, called triglycerides, are form when three fatty acids are connected to a glycerol molecule. A chain of carbon with an acid group at the end forms a fatty acid. The term staring(a) fat is use to describe fats virtuous with hydrogen they are normally solid at room temperature and in the main come from animal fats. Trans-fatty acids on the other hand are unsaturated, but crucially the alignment of the hydrogen atom makes it to a gr eater extent akin to saturated fat. The necessary lubrication for the tree trunk is provided by lipids they likewise provide insulation to puff and help to keep the bodies temperature stable. They also form lift off of the membrane social structure of mobile phones and help with synthesise eicosanoid molecules and hormones. Lipids are a concentrated form of energy, get to for immediate use but coffin nail also be stored for use later. Foods high in fat include meat, eggs and d air powery products. It should be remembered that the trunk ask fat and that foods high in saturated fat, trans-fatty acids and cholesterin increase the find of heart disease, whilst those foods high in omega-6 and omega-3 polyunsaturated fatty acids reduce the risk of heart disease.(Grosvenor MB, Smollen LA, 2006, p 152)Protein comes from twain animal and plant lines. More prosperous populations usually consume to a greater extent than animal protein sources. These tend to be high(prenominal) in bid, coat and calcium as well as saturated fats and cholesterol. Plant sources of protein are higher in unsaturated, fat, fibre and phytochemicals (chemical compounds found in plants, beneficial to the trunk) the building blocks of proteins are aminic acids. Some of these amino acids which the soundbox evoket produce in sufficient quantities are referred to as essential amino acids and are hence required to be part of a healthy feed. Chains of amino acids form different proteins and the shape of these proteins dictate their purpose. Amino acids from both the personify and the dieting are utilised by the cells to react with proteins as instructed by DNA. Amino acids are also used to interact with glucose and other non-protein molecules to provide energy. The need for protein is calculated by looking at the consumption of northward in dietary protein and the protein eat excreted by the body. The RDA (Recommended Daily Allowance) of protein for a healthy adult is 0.8 gram s per kilo gram of body pack. The requirement can increase depending on the state of the body, for instance pregnancy, breast feeding a baby, growth, physical activity, physical injury or illness. It is recommended that 10 to 35% of calories are interpreted from protein to maintain a healthy diet. Foods high in protein include chicken, beef, pink-orange and legumes.Vitamins are critical to our efficient physiologic buttes they are organic compounds that are important in the health of our go dones and clappers. They also boost the immune dodging enabling us to avoid illness and disease. They also have a beneficial load on vision and efficacy of logical argument. Vitamins do not have any energy of any calorific value they do however have a vital part to trifle in how the body uses lipids, carbohydrates and proteins. The body only involve small amounts of vitamins (and minerals) and are de followd as micronutrients. Their efficientness are easily reduce by exposure to ligh t, heat, air and over-cooking. They are undo in an alkaline surround. Vitamins are grouped by their ability to be water soluble or fat soluble, this trait determines how they are transported, absorbed and stored in our bodies. Most vitamins cannot be produced by the body and thusly need to be taken in our diet. Water and fat soluble vitamins are found in many varied foods. A normal matchd diet will provide all the vitamins needed by the body.Minerals do not contain carbon and are referred to as inorganic substances. Important minerals to health are iron, zinc, magnesium, calcium, yard and sodium. They differ from vitamins and macronutrients in that digestion does not degrade or break them down nor are they destroyed by heat or light. Independent of their environment minerals maintain their structure, for ensample the calcium in milk is the same calcium in our get ups and the sodium in household salt is the same sodium in our cells. Physiologically minerals are vital to many f unctions including the regulation of bodily fluids and the drudgery of energy, they are essential in maintaining healthy course and bones. They aid metabolic process by riding the body of harmful by-products. They are ordered by the bodys need for them in our diet, and how much of them are found in the body. They are ordered into dickens categories, Major Minerals and Trace Minerals. Those minerals that our bodys need to consume a minimum of 100 mg per day are termed Major Minerals and are found in the body in amounts of 5000 mg or more. Calcium, magnesium and phosphorus play a critical character reference in bone maintenance. Energy production is enhanced by magnesium and calcium boosts muscle efficiency. Chloride, potassium and sodium help in fluid balance, sulphur is seen as an active constituent of certain vitamins and amino acids. Major mineral sources are numerous and include meat, fresh growth, dairy farm produce and nuts. Chromium, fluoride, iodine, selenium, magnesium , copper, zinc and iron are main trace minerals. They are called trace minerals be cook the body needs 100mg or less per day. Iron is deemed to be important in keeping blood healthy enhancing the amount of oxygen transported round the body. Reproductive health and cell growth and development are maintained by zinc whilst selenium, copper and magnesium are antioxidants concealling free radicals. Iodine is effective in the production of hormones which regulate body temperature as well as metabolic rate and growth. Fluoride fights tooth decay and helps strengthen bones and the body needs chromium for the correct metabolism of fats and carbohydrates. Trace mineral sources are in the main the same as major minerals.Water which plays a key role in our health is an inorganic substance providing support to all variety meat of the body enabling then to function correctly. It is consumed in various forms much(prenominal) as pure water, soup, juices, imbibes and other liquids. It is also present in fruit and vegetables. Water intake must be adequate to maintain the balance of fluid in and out of our cells, helping the function healthy body temperature, muscle efficiency, nerve impulses, transport of nutrients and elimination of waste products.The chemical process and reaction and the physiological progressions in the body are hugely complex. They are all influenced and kept in harmony by all half dozen of the above nutrients. This harmony is called homeostatis. Blood pressure and blood sugar level and hundreds of other conside symmetryns are kept in balance and constancy.The nutrients provide the terminuss that payoff in homeostatis, water controlling body temperature by sw take when the body is hot. Proteins and lipids regulate the hormones which start and better various body functions. Vitamins, proteins and minerals control chemical actions throughout the body. This balance, this equilibrium this harmony this homeostatis is health, any inability of the body to control imbalance, inequality or disharmony, is illness.(Thompson JL, Manore MM, Vaughan LA, 2008)Effects of glucose on the chiefThe mitochondrial area of the sense is the engine room where intellect power is centered. This brainpower power is fuelled by glucose which is supplied to the brain in the bloodstream. The brain cells needs a steady sum up of glucose, the brain cannot store the glucose so an adequate supply is vital to the functioning of the brain, learning, concentrating and memory. The body obtains glucose from carbohydrates, fruit and vegetables, grains and legumes. (Very few animal foods are a source of carbohydrate, dairy products being the exception. Over supply of carbohydrates or sugar can restrict the brains use of glucose, departing in a degraded brain function, although the brain activity needs a lot of energy.(http//www.fi.edu/learn/brain/carbs.html)Effects of a high protein dietGenerally a high protein diet isnt harmful in the short term, up to four months at closely, and can be effective in losing weight. However in the long term and in conjunction with a decrease or elimination of carbohydrates can leave in various health difficultiesNutritional Deficiency. A overleap of fibre can result in constipation even diverticulitis and cancers pith Disease. A diet rich in protein, red meat and dairy for example can increase the risk of heart disease.Kidney Problems. A protein only diet can aggravate kidney problems causing difficulty in the kidney touch on waste products of the metabolism of the protein.If a person wants to try to lose weight on a high protein low carbohydrate diet they should be advised to try it in the short term only, the protein chosen should be lean meat, fish, skinned chicken and low fat dairy production. Anyone with diabetes, liver-colored or kidney disease or on long term medical specialty should be advised against it and to at least speak to their doctor.(http//www.mayoclinic.com/health/high-protein-di ets/AN00847)cellular respiration is a metabolic reaction where cells convert nutrients into energy with waste being a by-product. These reactions can be catabolic (production of energy by breaking down nutrient molecules) or anabolic (the consumption of energy and building of molecules) Cellular respiration is an important way for a cell to acquire energy enabling cellular regeneration(Campbell, Reece, Urry, Cain, Wasserman, Minorsky and Jackson, 2008)Definitions of calories and energyCalories soup up or energy can be measured in calories. The description of a calorie is the amount of heat it takes to raise the temperature of 1g of water by 1o C the converse is of passage also true, a calorie is is the amount of heat 1g of water releases when it cools by 1o C. (Campbell, et al 2008). It is as well to note that the calories on food labels are in fact kilocalories.The joule (J) is also a unit of energy, with one joule being equal to 0.239 calories. ane calorie is equal to 4.184 jo ules.EnergyThe definition of energy is that ability or capacity to alter things, particularly to do work against a immune force. (Campbell et al, 2008)The statement calorie free energy drink is a contradiction in terms in terms in that anything that has energy must have calories and of course vice versa. The label is therefore totally misleading(Campbell et al 2008) incision 2 Metabolism and DetoxDefinitions of ObesityThe medical definition of obesity is having a body mass index (BMI) of 30 or more. BMI is the ratio between height and weight and although it is widely used it is at beat a rule of thumb In Scotland BMI is the guide used in primary care to say if a patient is obese or not. Its use has been criticised as being inaccurate and that other techniques give more useful indications of obesityBody fat measurement using callipers cannon hip ratioBioelectrical impedanceWrist measurementWater translationThe problem with these techniques is that they can be cumber about, time consuming and expensive, whereas BMI can be read from a simple table.Overnourishment, overeating, consuming more food than the body needs for normal activity are the main executes of obesity but genes, physical activity and environment have a part to play as well.(Thomson JL et al 2008) muckle Point TheoryThe theory of Set Point intimates that a persons weight is restricted within confines pre-determined by the body. When a persons weight fluctuates, up or down, the body automatically compensates physiologically by altering the Basal Metabolic Rate (basal metabolic rate). It appears that this is all part of the bodys blueprint/DNA in the maintenance of homeostatis. This goes to explain why dieters routinely fail to keep any weight loss after they stop dieting.Yes, if toxins are present in the bloodstream they can have a direct influence on where the set point is set. Metabolism and body size are related. Metabolic rate is roughly proportional to body mass. Homeostatis is also propo rtional to body mass, the larger the mass the wider the parameter that homeostatis kit and caboodle within.(Campbell, et al, 2008)Changes to metabolismMetabolism is all the bodys chemical reactions, which have both anabolic and catabolic pathways, they husband the energy and material assets of the body.The conversion of food and drink into energy by the body is a function of metabolism. This complicated chemical process, the calories in the food and drink combine with oxygen to provide the body with the energy it needs. Even when the body is inactive the body stills consumes energy maintaining those willing functions such as, repairing cells, blood circulation, hormone production, body growth and breathing. The body therefore needs a certain number of calories is carry out these functions and is called the primary metabolic rate (BMR). Age, gender and body mass determine an individuals BMRAge. As the body ages, muscle mass decreases and fat becomes a higher component of body weig ht. This slows down calorific expenditure.Gender. Males generally have less body fat than females, muscle is greater in men than women as well.Body Mass. The larger the body mass, then the greater the calorific burn.Generally, if more calories are consumed than expended then the body will store the excess and result in weight gain. Of course set point theory, an individuals metabolism and predisposition to weight gain or loss comes into play. Energy needs for the bodys basic functions stay fairly consistent and arent easily changed. The basal metabolic rate accounts for about 60 to 75 per cent of the calories that are burnt all day.(Grosvenor MB, Smolin LA, 2006)Effect of muscle growth on metabolismYes, increasing muscles increases the bodys resting metabolism, which in turn consumes more calories. The larger the muscle the more cells, the more cells the more energy required. Muscle mass is increased by strength raising(Campbell, et al, 2008DiurecticsA diurectic is a drug that in creases the excretion of accumulated water in the body. This can be beneficial in the treatment of certain illnesses, but can also have serious side effects. The diurectic effect of drugs and some herbal remedies can have a superficial effect on weight loss, as the body is predominately made of water any reduction gives an immediate loss in body weight. The serious side effect on the homeostatic fluid balance in the body, causing the kidneys to filter out more water out of the blood resulting in dehydration and potassium loss, muscle pain, stomach ulcers, impotence and painful enlargement of the breast in men.(Campbell, et al, 2008)How toxins are cleansed from the bodyThe body uses major carcasss to cleanse the body of toxins they are the sweat glands, the digestive brass, the urinary system and the liver. These systems remove more toxins than all other systems put together. Keeping these systems in good order (water is vital to them all) enables the body to prevent disease and i llness.In this modern age we are all more and more at risk from the thousands of toxins in our environment ranging from, cleaning agents, pesticides, car exhausts, pollutants in the air we breathe and poisonous compounds in everyday objects and materials. They are all chemically different, some are more toxic to the body than others, they can be breathed in, ingested, absorbed through the skin or cuts and abrasions they have even been shown to cross umbilical turning point and enter the unborn childToxic contamination can cause the production of body fat in the body, this is because the body tries to counteract the toxic substances by cleaning them from the organs of the body and storing them in the safer area of body fat, another example homeostatis.(Thomson JL et al 2008)Types of body image issuesMitchel is at risk of developing a body image problem, mainly by mates pressure and he should take seriously the advice given. Body image problems can lead to eating disorders with cal amitous results, the two most common eating disorders areAnorexia nervosa. The refusal or physiological inability to sustain body weight.bulimia nervosa. Binge eating then vomiting, purging or overuse of laxatives.(Thomson JL et al 2008)Hormones and HomeostatisSugarSugar is one of the most common foods, it is also a simple carbohydrate, meaning that the body can process it very quickly into energy. Complex carbohydrates are slower to release the glucose our body uses for energy. When we eat sugar our blood sugar levels increase and we get an energy boost. Sugar is derived from carbohydrates.(Youngson R 2000)Types of blood sugar diseasesBlood transports sugar round the body to where it is required. The endocrine system controls hormone levels in the body these hormones affect many different functions in the body but as far as blood sugar levels are concerned, when blood sugar levels rise the endocrine system stimulate the pancreas to secrete insulin which reduces the sugar level to normal. Diabetes is caused when the pancreas cannot produce insulin resulting in blood sugar levels being unregulated. Consequently, the absence of insulin, muscle protein cannot be utilised resulting in muscle wastage, also sugar accumulates in the blood and the kidneys have to process it and excrete it, the sweet smell of a diabetics urine is a result of this, for the kidneys to excrete the sugar it needs large amounts of water, which give rise to two of the symptoms of diabetes, raging thirst and excessive urination.Hypoglycaemia is a medical condition indicated by lower than normal blood sugar levels, one of the most serious implications of hypoglycaemia is less than adequate supply of glucose to the brain which impairs body function, from feeling unwell to seizures, unconsciousness and even brain damage. The ravages of too much or too little sugar in the blood can be very serious therefore the body and its endocrine system are mechanisms to keep the body homeostatic, in balance , in kilter. Hypoglycaemia is most often a result of diabetic treatment going wrong. breathing in of carbohydrates/sugar will raise the blood sugar level.(Youngson R 2000)Types of hormonesThe hormonal glands in the body regulate appetite, these glands produce several appetite regulate hormonesGherlin is a hormone which stimulates the appetite, whilst PYY another hormone in the digestive system, signals the brain when the body has had enough to eat, similarly, another hormone leptin, regulates appetite by causing the hypothalamus to suppress appetite. Leptin may also trigger the body to burn stored fat. interrogation is still on-going but who knows, maybe one day these hormones could be used in the treatment of obesity.(Wadden TA and Stunkard AJ, 2002)Effect of restricting carbohydratesA diet restricting carbohydrates will reduce blood sugar level step-down the supply of glucose to the brain, which cannot store glucose, this sugar is used in by the brain in cell management. A sca rcity of glucose to the brain would certainly cause headaches fatigue, the bodys homeostatic function may well cause carbohydrate cravings.(Youngson R 2000)

From mail conveyance air transportation moved to passenger, transport where the industry has either finished established its dominance especially when it comes to transporting passengers over long distances in very(prenominal) short periods of time. The returns offered by for-hire carriers can be classified into all-cargo, air taxi, commuter, charter and international run (Coyle et al, 2006159). All-cargo carriers much(prenominal) as FedEx and UPS airlines ar principally concerned with the transportation of cargo. Federal chatter companionship, which is a cargo airline, is ground at Memphis in the United States of America.Federal be do throne to a fault know as FedEx is the largest airline globally with regard to freigh t lots tho in terms of fleet size, it is the worlds second largest airline (Zhang, 200698). The muckle provides direction and financial reporting for a estimate of companies, which collectively make do chthonian the Federal press out name globally. The companies include FedEx Ground, FedEx Express, FedEx Office, FedEx Freight, FedEx emoluments, FedEx Trade Networks and FedEx utilisation Critical (FedEx.com, 2010110). Before the Federal Express became Federal Express potful it was cognize as FedEx besides it adopted the current name under which it currently operate in 1998 when it acquired Caliber System Inc. Federal Express locoweed built on its specialisation of extend bringing service and formed more diversified gild which incorporated different but related businesses (Denton, 199286). Federal Express tidy sum is the leading firm in the transportation industry globally. The company has managed to attain its current position by incorporating what it takes to be a major(ip) player in the global marketplace (Gp-Training, n.d.). FedEx community has built superior virtual, physical and people network to signifier network economy in the global scale.The following discussion allow for seek to conduct a strategic attention compendium of FedEx found on two models porters cardinal forces model and the wonk synopsis. The two models charter been selected based on the reason that they provide a step-by-step analysis of an organization. They are objective and can enable a planner or strategic manager to make accurate predictions of a business or project. Further, they greatly assist in prior determinations before roof investments are made, for instance, they greatly assist in determining whether the goals and objectives of a particular business are attainable. bone up Analysis and five forces model of Federal Express CorporationIntroductionSWOT analysis refers to an evaluation technique deployed in determining the strengths, weaknesses, op portunities and techniques in a business venture.On the other hand, Michael Porter established a structure that models a business as beingness pin downd by five main forces. This model is very important and can be used by industries to understand their operations better. match to Overbeck (2009126) porters five forces, which is a model for industry analysis, include extend tory, terrors of substitutes, Buyer strength, supplier magnate and Barriers to launch or holy terror of entry (McGrew Wilson, 198275). In addition, FedEx SWOT analysis presents various opportunities as easily as strengths of the company, which shoot made it plow one of the market leaders globally. However, the company too has a recite of threats andweakness that should be addressed to be able to become change surface more prosperous in future.Source Hill, C. and Jones G. (200967). strategical trouble possibility. sweet York Cengage Learning.Porters Five Forces modelRivalry fit in to Hill and Jones (200942), competition in the midst of rival firms accord to traditional economic model drives profit to last zero. However, competition is not perfect and businesses are not basic still footing takers but they strive for competitive advantage over rival firms. Application of rivalry, which is Michael porters first force to the Federal express, is evident. For instance, the corporation was faced with imminent rivalry argufy before it occupied the current position in the industry. For instance, the entry of competitors in their market. UPS in particular, posed a major threat. The company was ready to spend enormous sums of money in market penetration. For example, it invested in a thirty million dollar ad for purposes of competing with FedEx. Another challenge facing FedEx is the progressive developments in technology which act as substitutes to transnight mail spoken communication, for example, fax and emails. The entry of UPS into the market posed a severe threat to Fe dEx, serious enough to cause Pauline and Farhoomand (200088), to report that the transportation pot of FedEx was going down.FedEx Corporation responded to the threat of rivalry that threatened its progress and in January 2000, it resorted to reorganize the company into groups operation by doing business with the whole FedEx family. tally to Hill and Jones (200942) it is important to reconsider strategy in order to manage effectively in the market. The theory of Porters five forces model state that such action should only be taken after understanding the structures of the industry (Goodwin, 2001178). The resolution was that the five subsidiary companies and FedEx corporation was to compete collectively but to function independently, a strategy that boosted their pursuit for an advantage in the industry. This is in accordance with the strategic management theory and the model of Porters five forces, which pass on advocates the scrutiny of competitive forces in the market before i dentifying threats and opportunities as puff up as coming with a suitable strategy (Hill Jones, 2009201).Another strategy that FedEx Corporation used was alter point of intersection differentiation by embracement innovation and offering high quality products and services to customers. check to (Goodwin, 200067), FedEx Corporation pooled its marketing, sales and customer service function that enable customers to access services of the group at a single point. The reorganization cost FedEx Corporation 100 million USD in a span of three years, but the end justified the means. These measures retained FedEx in the market, but did not nettle UPS which in a number of years has managed to scoop its fair theatrical role of the market. Today, FedEx has grown into a multi- cardinal corporation owning various companies namely the FedEx corporation, FedEx Ground, FedEx Express , FedEx Freight, FedEx custom critical, FedEx Trade Networks and FedEx Kinkos .On the other hand, UPS has grown to the largest package delivery company on the globe owning companies like UPS Mail Innovations, UPS Air Cargo, UPS working capital Corporation, UPS Consulting, UPS Aviation Technologies, UPS Mail Boxes Among Others.Threat of SubstitutesA substitute product in Porters model is a product in other industries which could be deployed as an alternative to another product from a different industry. The threat of substitutes according to the five forces theory therefore exists when the demand of a product is stirred by change in price of a substitute product (Overbeck, 200956). The same way the price elasticity of a product is bear on by same substitute products hence when more substitutes become available, it go demand, which becomes more elastic because customers have more alternatives. Competition can be endangered by threat of substitutes when they come from outside industry. Strategic management theory and five forces theory according to Hill and Jones (200953) assert that foundat ion of very close substitutes poses a strong threat in the market and leads to reduced profitability. To deal with such a challenge the two theories co-occurrence the idea of diversifying a companys products and service as FedEx did (Hill Jones, 200953-54).FedEx embraced technology and innovation, which enhanced dependability and speed of deliveries in the firm. The company adopted next day delivery services, which completely revolutionized the industry. This made it preferable to many customers because it became reliable and convenient. Perishable commodities could turn their intended destination with appropriate time, which consequently reduced competition among its rivals. consort to Overbeck (200945), FedEx Corporation gild under the leadership of Smith pioneered a number of technological breakthrough that propelled the firm above all others. For instance, over lakh PCs loaded with Federal Express software made to log and refer customers into bring in and ordering syste ms were introduced in FedEx. Federal Express similarly, became the first to give up their drivers with handle scanners, a device that alerted customers when packages were either delivered or picked up. fit to Pauline and Farhoomand (2000113), Federal Express Corporation was the first to launch a website with tracking and tracing capabilities. Such strategies helped the company to grow without feeling the pinch of the threat of substitutes.Buyer PowerThis is the impact that customers (buyers) have on a producing industry. According to Overbeck (200989), there are factors that determine the buyer power. Federal Express Corporation has been shaped by the buyer power especially corporate buyers who have enormous bargaining power resulting from the large amounts of purchases they make. Buyer power is also influenced by the castigateing cost. It is a fact that buyers power greatly influences FedEx. For example, it gained a huge share of the catalogue business because it was able to of fer buyers bring down prices as compared to UPS. The company has always tried to expand with the demand of its customers (Overbeck, 200989).FedEx Company has used selective information technology that has been quite significant in the globalisation of trade, effective and efficient sharing of information within and outside the company, ameliorate customer service and reduced costs of services offered by the company. As a result, the buyer power is skewed towards Federal Express Corporation because it provides the services that the buyer demands. According to five forces theory and strategic management theory, buyer power is a very significant consideration in designing business strategy (Hill Jones, 200950-52).On the other hand, buyer power also constrains FedEx in some ways. The delivery has nominal switching costs such that when a customer is not satisfied, they can easily switch to the competitors services. For instance, when UPS made its entry into the market, offering its services at half the price offered by FedEx, many of its customers disregarded the switching costs and moved to UPS. supplier PowerSupplier power illustrates the ease with which suppliers can determine prices. Supplier power id determined by the number of suppliers available in an industry, the distinctiveness of their services or products their influence over a company. The more supplier options open to a company, the less the likelihood of high supplier power.According to Hill and Jones (200952), a powerful supply has the ability to influence the producing industry. According to five forces theory and strategic management theory, suppliers can easily determine the future and progress of a firm and so can the deuce-ace parties (Hill Jones, 200953). While other rival companies in the industry were sub-contracting their shipment to third parties and buying space on commercial airlines, Federal Express Corporation tried to acquire its own transportation fleet and in the tenth year , it became the first company in the United States to achieve 1 billion USD revenue mark in ten years without corporate mergers and acquisitions. According to Farhoomand and Pauline (2000), Federal Express Corporation does not have outside(a) factors that influence its ingrained decision and operation and has been able to advance greatly in the industry this is because Federal Express Corporation has limited influence of buyer power.Barriers to Entry/ Threat of EntryHill and Jones (200943) argue that industries deliver some characteristics, which protect the lofty levels of profit of firms in the market, which hamper supererogatory firms from entering the market. It is this inhibition of additional rivals in the market, which is termed as barriers to entry. According to Strategic management and five forces theories, barriers to entry reduce rate of entry of modern businesses, which therefore maintains the high level of profit for those firms that are already in the industry (H ill Jones, 200987). The sources of such barriers include government created barriers, Asset specificity, patents and proprietary fellowship and organizational economies of scale. Federal Express is already in the industry and reign the industry already (Farhoomand Pauline, 200079). Therefore, it is not faced with any barrier to entry into the industry.FedEx and the other delivery companies already in the market like UPS are the cause of the barriers. They have large brand name as well as established relations with foreign countries. Smaller companies will have an almost impossible task of penetrating the market because of the large capital requirements. With little capital, it will be impossible to offer competitive prices. Further, ambit the standards set by the market giants is an uphill task.Federal Express SWOT AnalysisFedEx SWOT analysis presents how the company has been able to use information technology in defining its strategies (Quality-Assurance-Solution, n.d.). Infor mation technology apart from improving the performance has made it possible for the company reaches new associates or groups of people. SWOT analysis of FedEx Company involves analyzing strength, weaknesses, opportunities as well as the threats of the company in accordance with the SWOT analysis theory (Burger, 200812)Strengths of FedExSWOT analysis theory according to Burger (200813) is very instrumental in helping companies identify internal and external attributes and factor, which affect the companies resource capability. According to the theory, internal attributes are strengths and weaknesses magic spell external attributes are opportunities and threats (Burger, 200813). FedEx strengths in the transport industry include economical service delivery to customers. The company gives the needs of customers first priority. This has instilled customers with confidence in the company, thereby making it quite preferable among many people in the global market.In addition, Grignard (19 94) argues that the strength of the company is the ability to offer express mail services, which ensures that mails are delivered overnight. This has made the company to outdo many major players in the industry such as United States Postal Service in terms of service delivery as well as customer service. According SWOT analysis theory such strength is very crucial in making FedEx realize its objectives (Burger, 200813). FedEx Company also has a very strong brand name, which gives it its place in the global market.FedEx is known for its innovativeness. It has proved time and over that it is capable of initiating great ideas that all told change the market. For example, the purchase of their own airplanes and ships instead of hiring. This boosts a customers confidence in the company as they are guaranteed that third parties are not a party to the delivery of their parcels.Further, FedEx is known as a market leader. Its known for its use of advanced technology and effective communicat ions systems in all its operations. Its a recognized worldwide transportation company and its also known for its ability to take in smaller companies to expand its needs.Above all, its superlative strength is its brand name and the goodwill or account attached to it.WeaknessesSWOT theory according to Burger (200812) states that weaknesses are some of the internal conditions, which prevent companies from achieving their objectives. For instance, the dispute between the company and its pilots is an internal crack which could damage its reputation

Eal Observed In A Primary School

Eal Observed In A Primary School eruditeness a sec speech communication is angiotensin converting enzyme adaptation skill that proves to be necessary when various(a) cultures get it on together. For example, children from diverse linguistic backgrounds study slope as a bridge to better education. The Rationale for Planning for Children learn side of meat asan additional linguistic communication (2008) advocates that in provision for children who ar encyclopaedism English as an Additional Language (EAL), the following come across principles must be spy that bilingualism is an asset instead of a obligation for children who know more than than ace rough opposite row opposite than their bugger off tongue or primary actors line. This eldest style is essential non just in knowledge another wording but besides for ones identity formation. The EAL provider should keep the learner ch on the wholeenged cognitively with the continuous readying of linguistic and contextual support. Lastly, the acquisition of another voice communication should go debate in hand with the students cognitive and academic development within the aforementioned(prenominal) indoctrinate environment and the student would not make outside support. It is already integrated in the inclusive curriculum break inn to the learner.Cummins (1984) came up with a matrix to explain the dynamics of second oral communication acquisition development. peerless axis represents the BICS or the Basic Interpersonal Communicative Skills while the other axis represents the CALP or the Cognitive Academic Language Proficiency. Baker (2006) explains that students oblige in BICS when they communicate with contextual supports and props such as show-to face context embedded situations where they read the other persons non- literal gestures, hand movements and sounds to support verbal communication. On the other hand, CALP happens in context reduced situations requiring higher put up thinking skills such as analysis, synthesis or evaluation. This is commonly encountered in more academic learning and communication where speech is disembedded (Baker, 2006).This paper provide report observations in a primary school that embraces multi heathenceishism and multilingualism and analyzed match to theories and to its compliance to standards and policies for implementing English as an Additional Language (EAL). Observations were done for winder stage 2.The physical environment of the school and classroomUpon entering the school, a large map welcomes people with the sign thatread Welcome to our school. We come from all over the military man and we speak27 languages. For to each one language, it was machine- annoyible to the country of origin asindicated in the map. This sign gave a very(prenominal) warm welcome to anyone whovisited the school no matter what culture he or she comes from.An IT room is available for any EAL learner to usage whenever one occupys toconsult a computer for spelling or grammar or anything that pertains to the English language. This additional resource to support their learning is another feature that the school anticipates learners fills and provides them when called for.The classroom observe had a big expansive globe which represents a wide range of diversity is accepted there. The children tin can freely explore the globe and search for their own countries and link it to their inseparable language.A trained EAL teacher was employed by the school to dish up facilitate the cognitive, language and literacy development of distant children. Adults play a spacious role in the language development of children, as they need psyche who uses simple language in correct form and is flexible equal adjust his language to suit the childs (Clay, 1988). Having a good second language teacher is essential to learning the language more silverly. The researcher does not discount the fact that imitation of proper pron unciation and intonation is necessary. Hence, learners should digest attentive ears and retentive minds, and of course, cooperative tongues to be able to speak fluently in such language. Children alike need opportunities to practice speaking and auditory sense to the second language outside the language lessons, so that means they need a support system of learners to interact with.The school acknowledged and reckon the childrens different cultures. As an example, the school held a Polish mass renowned by a Polish priest on Tuesdays. Cummins (1986) contend that children ar empowered when their cultural roots atomic tote up 18 celebrated. Usually, when schools and teachers do not earnestly consider foreign students their congenital culture, these children see unaccepted and unworthy to pass to their classes, hence display inappropriate behavior. They capture lost in foothold of academic achievement and develop insecurities about their skin color, ethnic characteristics o r language accents. Such embarrassment develops stress or anxiety during class. The students family whitethorn likewise seem withdrawn or non-participative in their childrens schooling and feel the uniform sense of not belonging to the new culture they substantiate joined. In affect of this, culturally-relevant teaching must be learned by teachers. Such teaching takes into rumination the cultural background of the students at all times. It also keeps in mind cultural aspects in all interactions with students on both personal and educational levels. (Edwards Kuhlman, 2007). Students cultures, languages and experiences need to be acknowledged, valued anduse as important sources of their education because they deserve the best that society can give them. This involves teachers learning about students backgrounds and personal experiences to use as tools to make connections with these students. just about strategies that teachers can employ are the inclusion of the various historie s, contributions, perspectives and concerns relevant to the diverse backgrounds of students (The IRIS Center for Training Enhancements, n.d.). Incorporating these in the curriculum makes learning important to these students. Multicultural education using literature from various cultures engages such children in reading and writing and makes them eager to learn the social or cultural contributions made by various groups of people.Observations of the childrenIt was learned that the children in the school were not allowed to speak their native language within the classroom but they are free to speak it outside with their peers. This is part of their learning the English language in the classroom. This may be considered by the school as an strong way to immerse the children in the English language, however, the Rationale for planning for children learning English as an additional language (2008) recommends that children have free access to their primary language (L1) in order to fully understand their second or additional language (L2), so the classroom teacher should be more lenient in allowing children to use their L1 in class as a tool to learn their L2.There was quite a number of foreign students enrolled in the school. The researcher approached some and asked them some questions regarding EAL. Two Lusitanian children were observed to be peer-teaching. i was already fluent in the English language while the other was still struggling so the more adept one was helping him translate some words. Vygotsky (1962, as mentioned in Clay, 1998) emphasizes the value of childrens talk and their growing ability to articulate their apprehensiveness of their world orally and in writing. Taking part in negotiating meanings is part of the educational process, and Vygotsky believes that just being with others helps children learn. In observing the two Portuguese children, some theories may explain why the more English language-adept child uses their native Portuguese to te ach the less knowledgeable child. Swain Lapkin (2000) conclude in their study that the first language is by default, a tool used by students to learn their second language. Collaborating with other students in assesss for learning a second language, students try to make sense of the requirements and content of the task, focusing their caution on language form vocabulary use and overall organization, then turn to their native language to process and discuss before at last getting back to completing the task. Swain and Lapkin point out that without the use of their native language, they might not be able to accomplish the task efficaciously or it might not be accomplished at all. They argue that the insistence of not being allowed to access their first language in a linguistically and cognitively complex task of decode a second language task would deprive them of an important cognitive tool. They stress that bilingual programs that allow for the development and maintenance of th e first language while learning the second language are successful in both goals.The researcher interviewed two students who both spoke Spanish. When asked if they speak to each other in their native language, they admitted they only speak it at berth with their parents. They did not speak it in school and said they were more cheerful speaking in English because most of the time they were in school and with friends who all spoke the English language. In this case, Lamberts (1977) subtractive bilingualism seems to be taking place as the childrens first language is being extinguished by the second language which is English. Otto (2010) elaborates on Lamberts theories on bilingualism. One issue in second language acquisition is its effect on the first language of the individual. The immense concentration necessary to learn a second language may create a negative impact on the first language. This is known as Subtractive bilingualism. When a child becomes fluent in a second language due to immersion in that language, there is a strong tendency to forget the first language, causing disruptions in communication with family members who only know the first language. Transmission of cultural beliefs and parenting interactions would need a shared language for it to be successful. If not, social relationships with families or other members of the community who are monolingual may break down. On the other hand, in learning a second language, a child need not forget the first language, but can be fluent in both. This is called Additive Bilingualism which means that although a child actively learns a second language, concurrently, there is continued development in the home language (Lambert, 1977 Otto, 2010). The goal is to enhance language skills in both languages. In view of this, the case of the two Spanish boys interviewed by the researcher may also display additive bilingualism because they continue to speak L1 at home so far if they are gaining competence in L2 i n school and with peers.Two boys from Ethiopia do not speak the same language even if they come from the same country. In the different parts they come from, different languages were also used. One of the boys speaks three languages French, English and Portuguese because his mother came from Portugal and his father from Ethiopia. The other boy speaks Amharic which is similar to Arabic, but he is from Ethiopia. Leon (1996) has outlined the need for migrant workers and their families to be supported in gaining communicatory competencies to enable them to live more satisfying lives in English-speaking environments. He said lack of bilingual support for students impedes their motivation to learn, as they could not cope with other English-speaking peers, so they feel unwanted, and just skip school. Gaining English language efficiency for these children will also raise their self-esteem so they get to be more confident to develop more personal and academic skills.Although the observat ions were bound to what has been reported, it already gave the researcher a good demonstrate of how the school upholds the EAL program. The foreign children seem to be comfortable in the school setting as they have settled in well in a accept environment. The government consultation document Aiming High Raising the Achievement of minority Ethnic Pupils (DfES 2003) states that the particular needs of bilingual pupils are best met by means of a coordinated whole school approach led by headteachers and senior managers. (DfES, 2005, p. 14). The ethos of the primary school observed reflected a clear venerate for the multicultural perspective.Otto (2010) contends that one of the main challenges posed by the English as a Second Language (ESL) approach is the development, selection and implementation of effective strategies and instructional techniques to suit the diverse learners since they come from various backgrounds. The Rationale for planning for children learning English as an additional language (2008) takes upon Vygotskys (1978) concept of scaffold. As the term implies, scaffolds are temporary supports in the process of learning which are gradually taken away when the student is already undecided of learning without them. In EAL, hold up comes in three forms, One is scaffolding by adults by making their expectations clear by sharing learning objectives and criteria for success with the students by way of modeling and demonstrating the English language, recasting of the childrens language from their L1 and providing them with opportunities to use their whole language repertoire to aid them in understanding their L2. Another form of scaffolding is through with(predicate) collaborative work. They engage in small group talks or work in pairs, usually with children who are more adept in the language are polar with children who are less adept, such as the two Portuguese boys observed peer-teaching in the school. The teacher may also use scaffolding throu gh visual support, via pictures, props, models, frames and language prompts, graphic organizers, diagrams, maps, plans and essentially all the print and picture cues they put up in the environmental setting (Rationale, 2008). Most of these scaffolds were observed in the school.The numerous issues on second language learning, especially English, only prove that it is creating much impact on the development of children from diverse cultures. more than and more people consider its advantages and possible disadvantages. Such amount of heed is worth it because people think up of ways on how to maximize its benefits. Learning another language apart from ones native language helps children be ready to be highly competent in an increasingly globalized world. However, although they become bilingual, it should not be forgotten that they also become bicultural, and learning of one language and the culture that goes with it does not mean forgetting their original one. Teachers should take int o consideration that their non-English speaking students should learn English in both its context and language elements so the students gain a better understanding and appreciation of the English language.
