Narrative of the Life of Frederick Douglass Essay -- American History

Narrative of the Life of Frederick DouglassIn learning ab bug out the history of America from the colonization to the reconstructive memory I decided to read The Narrative Life of Frederick Douglass. Frederick was one of the very few literate slaves. He was an incredibly important character in American and African-American history. Though he was blessed with intelligence most slaves were not, he still lived the same kind of life of the typical slave.Fredrick Douglas was born in free state he does not know the date of his birth, as did most slaves. He never really had a chance to know his m another(prenominal), only having seen her four or five times. Fredrick taught himself how to read and write despite it being against his slave-owners wishes. He could not let his noesis be known to anyone except for other slaves. Fredrick saw his knowledge of words both as a blessing and a curse. White men were given supreme power over their black slaves and it corrupted their character. or so African Americans of the early to mid-nineteenth century experienced slavery on plantations similar to the experiences described by Frederick Douglass the majority of slaves lived on units owned by planters who had twenty or more slaves. The planters and the white masters of these agrarian communities sought to ensure their personal safety and the profitability of their enterprises by using all the tactics-physical and psychological-at their command to make slaves obedient. thus far Christianity was manipulated in a way that masters communicated to their slaves that God had commanded them to obey their masters. People like Frederick Douglass who preached abolition of slavery, only had to nurture the already existing spirit within slaves to strive for freedom.Only a tiny fraction of all slaves ever took part in organized acts of violent resistance against white power. Most cognise as Frederick Douglass did that the odds against a successful revolt were very high, and bitter expe rience had shown them that the usual outcome was death to the rebels. Consequently, they devised safer ways to resist white dominance. For Frederick Douglass, it was fall that his way of fighting the power was to become educated so that he may better understand his situation. However, he described that knowing that witwas the piece of land from slavery to freedom. (Pg. 20) Reading enabled me to utter my thoughts, and... ...obey his master-to do as he is told to do. (Pg. 57) He was referring to the wrongfulness of his wifes attempt to educate Frederick Douglass. This was the view held by most whites toward African Americans. Consequently, other adjectives such as lazy, irresponsible, childlike, and simple-minded were used by whites to describe the African American character. This portrayal stole the African American sense of independence and created the treacherously image of black childlike dependence on their white masters. That combined with the fact that most African America ns were born into slavery disallowed them any experience of freedom or of Africa by which they may make comparisons to their situation of total bondage. The slave owners struggle to control the slave brought out an evil in them that cannot be brought out by any things. The slaves struggle for freedom and the suppression by their masters broke their spirit, which is a large part of human character. America would not get hold of grown to be so great in such a short time without slavery, because of the economic value of it. But, it would not have been such a violent society then or such a violent society now if slavery had never existed.

Contemporary Australian Cultural Issues in the works of Harper Lee Essa

Harper lee examines key cultural issues in her novel to kill a mockingbird, such as racism, socio-economic status and prejudice. These issues are still relevant to contemporary Australian society. She examines these issues without her volume in many another(prenominal) different ways, from many different points of view and from many different opinions from the characters in the book.The book is set in a small town called Maycomb in America and takes place during the depression years. The town of Maycomb is a town which is old and is not well looked after and is described as dirty in the book. The people who live in and around Maycomb on farms are execrable people, as a result of the depression.The main characters of the book are the finches. The Finch family comprises of genus Atticus the father and his two kids Jem and scout who narrates the story. The story is about life in maycomb seen through the eyes of children.Life in Maycomb is full of issues such as racism, socio-econom ic status and prejudice. Racism and socio-econic status are easily the two most noticeable issues that the book revolves around. These issues are relevant to contempory Australian society in many different ways.Socio-economic status is the main theme at the start of the book. A good pattern of this issue is when Jem invites Walter Cunningham to have lunch with himself, Scout and Atticus, because he does not have any lunch money as his family is too poor to afford it. They nonplus down for lunch and Walter drenches his food with syrup and scout thinks this is ungrateful and rude so she remarks by asking him what the Sam hill he is doing. Walter was embarrassed and Atticus shakes his head at her and she protests but he has gone and drowned his dinner with syrup, hes poured it al... ...ou only have to look at the wars going on oer in the Middle East. They are all fighting over different religion which is racism. Terrorist attacks are also based on racism because a mathematical grou p of fanatics from all over the world do not like westerners this is racism. On a more local level you see it even at rail where racism is big because Griffith High School is such a Multicultural community, all the different groups of people are grouped together for example the Afghans and the Islanders, this starts fights and arguments in the midst of different races.Socio-economic status and racism are only two issues that Harper Lee examines, as there many more which include prejudice, maturity and increase up. Harper Lees issues that are discussed in her book to kill a mockingbird are still contemporary issues in Australia, because they affect us and have a significant impact on us.

To Learn...Or Not to Learn Essay -- Education

Have you ever been a student, and you think the teacher is just talking to hear themselves talk? Do you feel yourself world filled with information you will never use in the Real World? These questions have been asked some(prenominal) times and by many people. The school organisation in the United States is changing from the foundation to the top. The school system has failed many students by their teaching methods and also the textbooks students are forced to use. People such as Paulo Freire PhD and Dr. James Loewen have observed countless hours of good teaching and bad teaching methods. Freire observed and wrote astir(predicate) the different methods of teaching that are being used, and Loewen wrote about how the textbooks are only telling us certain parts of our history. Paulo Reglus Neves Freire, PhD was born in Brazil on September 19, 1921 and died May 2, 1997. Paul Freire was well cognize for his theories on education. His most noteworthy work was Pedagogy of the Oppressed . In 1993 an exert essay The Banking Concept of Learning appeared in continuum. This essay brings to light many ideas current students and alumni have long known teachers are just using the students head as receptacles for their knowledge. Freire noted many ideas on this subject that are true. however set back and remember your high school classes or even your college classes. A few examples of one construct Freire named the narrative concept is when the teacher teaches and the students learn, the teacher issues discipline and the students are the recipient and the teacher confuses the knowledge with their own professional authority, in which this limits the freedom of creativity for the students.

An some other major defect in the educational system was identified by Dr. James Loe wen, in which he discovered a plethora of misinformation in many History textbooks and other historical artifacts. America wake up, we have to learn the proper way to teach our education but we also have to get our history sequent before we send it out into the public.

Eric Eriksons Stages of Psychosocial Development Essay -- Erikson’s Ei

According to Eric Erikson, there atomic number 18 eight different social grades a person must go through as they mature. Each stage has a confident(p) characteristic and a negative characteristic. If positive characteristics are fulfilled then their future will look good. So to what extent can the lack of reinforcement to the positive characteristics of Eriksons psychosocial stages of development effect you? The cause can be preferably horrifying. Especially if all of the stages the only characteristics fulfilled are the negative aspects.Eriksons first stage was trust verses mistrust and it occurred from zilch to 18 months of age. The point of this stage is to establish trust. Erikson believed this was the most important period in a persons life. Since a baby depends entirely on his/her parents, the care giving plays an important role in the shaping of this stage (Cherry, 2011). If the child successfully develops trust then the child will feel riskless and secure in the world , but the lack can lead to thoughts of an inconsistent and unpredictable world (Cherry, 2011). In the business world, the lack of trust can take a crap a whole new problem. The lack of trust can lead to the unseen cost in life and business as said by Stephen Covey (2006). Lack of trust creates hidden agendas and a guarded communication, which slows the decision-making process (Covey, 2006). When there isnt trust in a situation, it hinders productivity, innovation (Covey, 2006).The second stage is autonomy verses shame and doubt. This occurs from about 18 months of age to 3 years old. The basic virtue of this stage is will can they do things on their get or do they require the help of others? Erikson believed that children around this age wanted to develop a greater sense... ...r past with little or no fall and will be satisfied overall. If a person is unsuccessful in this phase they will feel that they wasted their life and they will only entail of regrets. They will feel despai r (Cherry, 2011).Eriksons stages of psychosocial development were complex, but simple. It is something everyone will go through and experiences will always be different. The lack of reinforcement to the positive aspects of his stages can lead to quite a disaster. Surprisingly, previous stages are highly influential to the proceeding stage. The lack of reinforcement to the positive aspects of his psychosocial stages can have a very devastating effect on a person. This is because the effects built up rather than taking the place of one another. The effects are quite horrifying, but with the right environment, experiences and beliefs, everything can go well.

Unit Three – Marketing P3

Marketing Research Market investigate indicates decisions made by a business, in this case Tesco, by helping the decision makers understand undercurrents of its market. This process involves investigate done on customers, competitors and the everywhereall marketing environment. For example, when Tesco is promoting a product, they need to know the likes and dislikes of their targeted consumers in order of magnitude to target the correct market successfully. They would also be required to research about their competitors, to find out if by whatever chance they offered a product that was similar, and how they would differentiate their product from it.Also, as an overall, they would be required to research the environment of the market, as well as the size of their target market, in order to decide how they ar going to offer the product to the consumers. Example sold in store, online, or both. Primary and Secondary Research There are both types of research Primary Research Seconda ry Research Information for these types of research crumb be done internally within the make-up, or externally, from another organization or source of cultivation outside the organization, in this case Tesco.When information or data is collected for a certain purpose and has not been gathered before is known is primary research. Internal primary research data source could lie down of The businesss sales figures of products A central database retention customer data External primary research data source could consist of Various questionnaires and surveys A variety of focus groups and interviews Observation techniques When data or information that has been collected before, either internally or externally, is utilize for research is known as unoriginal research. Another name for secondary research is desk research.Internal secondary research data source could consist of Sales and regional reports Market research gathered in the past External secondary research data source cou ld consist of Websites and trade journals Newspapers and books Public reports Census data Industry reports For business like Tesco that operate in many different fields, secondary research is more cost-effective, before they decide to conduct primary research. This allows Tesco to consecrate a better understanding of the market, as well as recognize any major obstacles before conducting expensive research.Secondary research also allows them to make assumptions based on similar products and therefore, once primary research is conducted, it can be used against the assumptions to evaluate and compare. This will help indicate how much primary research they are required to do and therefore they dont end up doing too much that is not required. However, Tesco is required to stick the limitation of secondary research into consideration The information may be outdated The information may be biased in order to promote particular causes The methods used to collect the research may be unreli able.Qualitative and Quantitative Research Research methods can be qualitative, quantitive or can include both methods. Well-planned market research consists of both methods in order to take with a good combination of information revealing different things about the same market. Qualitative research is one-sided and normally unrestricted. It normally is gathered through interviews with customers or focus groups and therefore result in a wide range of research based on personal experiences and feelings.A qualitative question allows the individual go give a ample answer and not based against options. Qualitative research can be used to Find the perceptions of customers about an organization or brand. Discover how changes in impairment and other factors affect customers and spending decisions. Explore customer preference, interests and other factors. Quantitative research involves numbers and figures that can be examined mathematically or graphically. This may consist of sales figur es, market values, etc. , as well as responses from customers on questionnaires.This is only categorized as quantitative research if the responses from the customers a chosen from serial publication of answers provided on the questionnaire. The difference among quantitative and qualitative research QuantitativeQualitative ObjectiveSubjective Tests theoryDevelops theory Concise and narrowComplex and broad Measurable Interpretive Basic analysis NumbersBasic analysis wrangling and ideas Logical and reasonableDialectic Establishes relationshipsDescribes meaning Experimental settingNatural setting Uses of marketing researchThe information collected for market research prevents businesses like Tesco making wrong business decisions. If the product cause for Tesco progresses a new product without market research, then the business is not moving forward on reliable sources and therefore are unaware if customers are interested in the product or not. This indicates, effective market researc h improves the chances of success and reduces the risks. Tescos can also measure progress effectively over time. This can be done by, carrying out market research, to found out the awareness of the product before managing national advertising campaigns.Once they have conducted the research, they can posture their national advertising campaigns into action and again conduct research and compare the two. Therefore, this indicates, market research can be used to measure progress as well as the effects of marketing activities. Limitations of market research costs, effectiveness and logicality of data collected Weather market research is done at a small or large scale, any time is required to be performed accurately and appropriately otherwise it gives irrelevant results.All market research conducted has the chances of be wrong no matter how well controlled and planned. There are various reasons why market research may not provide accurate or good results but a usual problem is decid ing whether the research conducted really measures what it claims to be measuring. Marketers for Tesco are required to decide how reliable the information they have obtained is. Also they need to take into consideration, if the research contained had different respondents or different set of data points, would the results be similar. rigor refers to whether the research conducted is what it intended to be. Validity involves dependability, which means, a valid measure must be reliable. But, reliability doesnt have to link to validity, a reliable measure is not required to be valid. The difference between reliability and validity Reliability guesses the point to which an tool processes the same way each time it is used in under the same conditions with the same subjects. Validity involves the point of accuracy of your measurement.For organizations like Tescos, validity is considered more important than reliability because if a process does not precisely measure what it is supposed to, there is no use of it and therefore it being reliable is useless. Costs are also an essential consideration for Tesco when carrying out market research, as they are required to take into consideration if they money spent is worth the research undertaken and its potential benefits to the product, as well as the organization. A lot of time, effort and money can be spent on market research and in the end the solution discovered might not be worth implementing.

In Diesel Engines The Phenomenon Engineering Essay

Abstract. In Diesel engines, the phenomenon of nighttime formation is extremely dependent on the temperature inside the burning chamber. NOX formation is encouraged when the temperature inside the burning chamber additions 2000 K. Therefore, there is a demand to maintain the peak temperature inside the burning chamber under decl ar in order to cut down NOX formation and emanation.A simple method to cut down the NOX emanations in Diesel engines is belatedly injection of fuel. Although it reduces the NOX formation yet in bend increases the fuel ingestion by 10 15 % . A more sophisticated technique would be exhaust gunman recirculation ( EGR ) . When some of the stinks gas is taken, assorted with the fresh charge and into the utilization, the O concentration decreases which suppresses and greatly reduces the NOX formation. It is non every(prenominal) patch simple as it sounds because cut downing the O concentration would intend that less O is avail sufficient for burning whi ch would take to uncomplete burning and therefore particulate matter formation. Therefore, a tradeoff between the NOX decrease and particulate formation has to be made. The particulate formation is non much of a job as the sum of the unburnt atoms in EGR can be controlled utilizing a particulate trap, which in bend would cut down particulate emanation every bit good. incomingDiesel engines are well-known for the low fuel ingestion and really low CO emanations, but unluckily the NOX emanations are comparatively high. over the past few old ages, rigorous emanation criterions have been developed and imposed on NOX, fume and particulate emanations emitted from the automotive Diesel engines around the Earth, babble the inauspicious effects of the pollution caused by these emanations. In order to run into the environmental statute laws, it is of import to cut down the NOX exhaust emanations as high NOX emanations still remain a major job in the pollution facet.Some of the basic steps for decrease in vehicular emanations include direct injection, turbo-charging, inter-cooling, burning optimisation both with and without swirl support, multi-valve cylinder caput, advanced force per social unit area ignition trunk, electronic control management constitution, lube oil ingestion control etc. Regardless of the advanced engineerings like those mentioned above, engineerings like fumes gas recirculation ( EGR ) , soot traps and exhaust gas after-treatment are of huge importance excessively, to provide for the progressively tough challenges posed by the environmental emanation criterions.Mechanism of NOX formationThe major hinderance encountered in pinch the formation and commanding owes to the fact that burning is extremely heterogenous and transient in Diesel engines.NO and NO2 together are regarded as NOX but there are typical differences between the two pollutants. NO is a colorless and odorless gas, while NO2 is a ruddy brown gas with sulfurous olfactory propert y. Both the gases are considered toxic, but NO2 has a high degree of toxicity, which is 5 times greater than that of NO. Attention to command of formation of NO has been given, before and after burning and therefore the sum of NO2 can be controlled excessively, as it is mostly formed by oxidization of NO ( Levendis et al 1994 ) .NO is formed during the station fire burning procedure in a high temperature part. The formation mechanism was suggested by Zeldovich ( Heywood 1998 ) . The chief beginning was the oxidization of the N nowadays in the atmospheric air. The reactions regulating the formation of NO from molecular N are N2 + O NO + NN + O2 NO + ON + OH NO + HThe chemical equilibrium shown indicates that for burned gases at typical fire temperatures, NO2/NO ratios should be negligibly little. Experimental information shows that this holds square(a) for start ignition engines, whereas in Diesels, NO2 can be 10 to 30 % of the entire exhaust emanations of oxides of N. The NO fo rmed can be converted rapidly to NO2 as a consequence of few reactions such as NO + HO2 NO2 + OHSimilarly, transition of this NO2 to NO occurs NO2 + O NO + O2Unless the NO2 formed in the fire is quenched by blending with the ice chest fluid. This account is supported by the highest NO2/NO ratios which occur at high burden in Diesels, when ice chest split could slake the transition back to NO are widespread ( Wood 1988 ) .The atomic O concentration depends on molecular O concentration every bit good as local temperatures. Formation of NOX is about absent at temperatures below 2000 K. Hence, any technique which may be able to maintain the burning chamber temperature below 2000 K will be able to cut down NOX formation.EGR technique for NOX decreaseEGR is an effectual style to cut down the NOX formation. Exhaust gases consist chiefly of CO2, N2 and water supply bluess. The EGR is normally defined as OrThe most widely recognized accounts as to how EGR reduces the NOX formation are i ncreased ignition hold, increased heat capacity and dilution of the intake charge with inert gases. The increased ignition hypothesis holds true as when the EGR causes ignition hold, it has the same consequence as late injection. The heat capacity hypothesis provinces that add-on of the inert fumes gases into the intake charge increases the boilers suit heat capacity of the mixture which consequences in lower temperature rise for the same heat release. As for the 3rd theory of dilution, the EGR reduces NOX formation by increase the sum of inert gases in mixture, therefore cut downing the O concentration, finally ensuing in decrease in adiabatic fire temperature ( Pierpont et al 1995 ) .Deterioration in burning takes topographic point at high tonss so it gets hard to utilize EGR as this may overly increase fume and particulate emanations. At low tonss, the unburnt hydro light speeds would likely re-burn when EGR is employed, therefore increasing the brake thermic efficiency and cut down the sum of unburnt fuel in fumes.As mentioned earlier, utilizing the right sum of EGR is a via media between decrease in NOX and an addition in carbon black, CO and unburnt hydrocarbons. For EGR values of above 50 % , manipulation of particulate trap is recommended due to important addition in particulates formation. The EGR is known for decrease in O concentration and this changes the construction of the fire and the continuance of burning, which are the most of import factors act uponing NO formation.The figure below shows the decrease in NOX emanation due to EGR at different tonss.Figure 1. signification of EGR on NOX2.1 Problems faced while utilizing EGRWhen utilizing EGR in Diesel engines, certain jobs are faced, like ( a ) increased soot emanations, ( B ) debut of particulate affair into the engine cylinders. It is rather obvious that when the high speed carbon black particulates are encountered by the engine constituents, the consequence would be scratch. Sulphuric ac idulent and condensed H2O in EGR besides cause corrosion. Harmonizing to some surveies, cylinder walls have been damaged due to lubricating oil s decreased capacity, which is due to blending of carbon black atoms carried by re-circulated fumes gas. This necessitates the consumption of efficient particulate trap which is effectual in cut downing fume, unburnt hydrocarbons and NOX emanations at the same time.The particulate trap requires periodic replacing when the pores get blocked due to choke offing of carbon black atoms which would increase backpressure to the engine fumes, and therefore impacting engine universe presentation. Other methods for decrease in particulate emanations include multiple injections, boosting and high fuel injection force per unit areas.Categorization of EGR systemsAssorted EGR systems have been classified on the footing of EGR temperature, constellation and force per unit area.3.1 Classification found on temperatureHot EGR Exhaust gas is re-circulated without being cooled which increases the intake charge temperature.Fully cooled EGR The fumes gas is to the full cooled utilizing a water-cooled heat money changer before it is assorted with the intake charge. This may ensue in condensation of wet in the fumes gas, ensuing in H2O droplets which would do unwanted effects inside the engine cylinder.Partially Cooled EGR In this method, the fumes is non wholly cooled to avoid the H2O droplets formation and therefore the temperature is kept merely above dew point temperature.3.2 Classification based on constellationLong Route system ( LR ) In an LR system the force per unit area bead across the air consumption and the stagnancy force per unit area in the exhaust way exercise the EGR possible. The fumes gas speed creates a little stagnancy force per unit area, which when combined with the low force per unit area after the consumption air, gives rise to a force per unit area difference to carry through EGR across the torque/speed scope o f the engine.Short Route system ( SR ) SR differs from LR in the method used to put up a positive force per unit area difference across the EGR circuit.The usage of variable nozzle turbine ( VNT ) is another manner of commanding the EGR rates. Most of the VNT systems have individual entryway, which reduces the efficiency of the system by exhaust pulse separation.3.3 Classification based on force per unit areaTwo different paths, low-pressure and hard-hitting path systems may be used for EGR.Low force per unit area path system The transition for EGR is provided from downriver of the turbine to the upstream side of the compressor. Using this method, EGR is possible up to a high burden part, with an obvious decrease in NOX. High compressor mercantile establishment temperature and intercooler clogging do act upon the lastingness.High force per unit area path system The EGR is passed from upstream of the turbine to downstream of the compressor. In this method, despite possibility of EG R at high burden parts, the extra air ratio lessenings and the fuel ingestion increases drastically.

Ethics of Ecology Essay

Ethics of ecology focuses on sustaining clientele and environment. Ethics is a set of principles about right and wrong and how forgiving beings should be lead. Ecology is about inter- relationships between living organisms (both plants & animals) and between biological & physical entities. As people promptly realise that the environment is a limited resource, sentience all over the world of the necessity to protect and save the environment has grown as well. From the Bill of Rights, Chapter 2, of the S.A. Constitution, Everyone has the right a.to an environment that is not harmful to their health or well-being and b.to have the environment protected, for the benefit of present and future contemporariess, through reasonable legislative and other measures that i.prevent pollution and ecological degradationii.promote preservation and iii.secure ecologically sustainable development and use of natural resources while promoting justifiable economic and social development Major man ifestations of environmental abuse include global warming, depletion of the ozone layer pollution of air, wet, resource depletion toxic waste and major health risks. From the extract we read that water supply has also become an ethical issue and we contain Coca Cola and Nestle at the brim of this. Ethics of ecology are concerned with rights as the Right of future generation which state that, all person has the right to inherit an uncontaminated planet on which all forms of life may flourish.The idea is that present generation has to bear a disproportional burden for the sake of future generation. Since we can not undo the world it is then better if we hand over a resourceful environment to the undermentioned generation, not an environment in its worst state.One may argue that, is it fair that the current generation get the benefits of using the resources and leave burdens for the future generation, in distributive justice perception this is unethical, therefore its better we fix what we can now rather than making things worse. There is also the right to a livable environment, that everyone has a moral and legal right to a decent livable environment. A livable environment is essential to the fulfillment of our own capabilities. At first Coca Cola in its stage business resulted in depletion of water much worse for the current generation, It is said that, there was severe water shortages from farming(prenominal) neighbours of the plant which means the future generation would find the environment in its worst state. It appeared Coca Cola was just concerned with prioritizing profits and consumption of water. As such Coca Cola deprived the community of the right to a livable environment and threatened the right of future generation hence it was taken to task.But in a twist we see Coca Cola owning up to its actions, it reduced its water usage by 24%, installed rain water harvesting systems in its plants hence it became a leader in water management practices . Coca cola further recycled water, replenished water and gave back safe alcohol addiction water to the community. Now thats upholding the rights of future generation and that of a livable environment. On the other hand its Nestle which its main beverage business is bottled water. This has raised criticism and ethical issues of water wastage, as it takes three litres of water to make one litre of bottled water. The issue is that if we waste so much now what will the future generation have.Focusing on the tragedy of the commons, the concept stress that there is real value in these free resources as water, as such there has to be a protection system in place to safeguard the value of these free resources. From the extract we see that some governments have already begun to act against bottled water. Even though Nestle have taken the initiative of water conversation, their means are not as aggressive as that of Coca Cola, Nestle still contend that bottled water is the most environmenta lly responsible consumer product in the world even though we know so much water is wasted, and the saddest thing is that it is most promoted in developed countries due to increased materialistic cultural values even though tap water is perfectly safe in those countries.It implies then that Nestle takes for granted water, as a limited resource showing little emphasis on saving and more on consumption. Nestle does not only waste water, the bottles are also biodegradable, one may ask, has Nestle taken any initiative to accord with waste management of the bottles. Not only will humans suffer from water wastage, but the bottles will ultimately harm the environment. An ethic of Ecological holistic theory comes to play, that the environment bears the interference with nature. These bottles end up in rivers, lakes, the oceans polluting the water and marine live hence the environment right to have its integrity, stability and beauty is compromised. endIn conclusion it is necessary to embra ce the need to conserve the environment so that business and human life are sustained in future. before long we are being scotched by earlier ignorance of people who did not preserve the environment, there is global warming, change of climates and seasons, characterised by uttermost(prenominal) coldness or extreme hotness, scares rainfall in some parts of the world and persistent floods in some. Adopting Initiatives as going green, recycling, reducing, reusing and respecting rights of the environment and non-human life will help sustain business and environment, and business ought to take autonomy over their acts.

Consideration Essay

An Agreement here is defined as every tell and every set of promises, forming the condition for each otherwise, is an agreement defined under slit 2(e) of Indian Contract Act, 1872. Making a contract is simply a way of facilitating amongst other things, the exchange of goods and services. Under a contract the, digressies voluntarily read their obligations or undertakings.Consideration is the recompense given by the party contracting to the other. 2. Consideration is the price for which the promise of the other is bought, and the promise thus given for respect is enforceable. 3. Consideration means whatsoeverthing which is of some value in the eyes of the law. 4. A valuable musing in the sense of the law, may consist either in some right, inte ease, profit or benefit accruing to the one party or some forbearance, detriment, loss or responsibility given, suffered or undertaken by the other.If a hand gives a party a choice of alternative obligations, each alternative on its ow n must constitute sufficient consideration for the return promise. If a promise is void or voidable e. g. , due to the incapacity of the promisor the sufficiency of the consideration is not necessarily negated.The judges, when they exercise this power of interference, are compete an extrinsic test which frustrates the expectation of the parties. It does not follow however, that such a test is necessarily harsh, still less that it is illogical. In some of the cases the law is settled, other are shrouded in controversies but in entirely of them the grounds of interference seems to be the same. Consideration made not be adequate and may, on motive be extremely tenuous, but it must comprise ome element which can be regarded as the price of the suspect promise and simply to repeat an live obligation may well seem to offer nothing at all.It may be appreciated that a person, who by his official status or through the operation of the law is under a public duty to act in a certain wa y, is not regarded as furnishing consideration merely by promising to discharge the duty. For example, no one would expect a guardman to bargain with a citizen for the price of his protection. In the case stated the defendant argued that this meant that they were not obliged to net for the large number if policemen who attend their ground at home matches because, in present conditions of crowd behaviour, a major police presence at the ground was necessary to preserve law and order.The Court of Appeal thought that there was a fundamental difference on the facts. In the Glassbrook case the threat to law and order was external to the parties since neither could call off the strike. In the present case, the defendant had voluntarily to put on their matches at times, typically Saturday afternoons, when large attendance and therefore large possibilities of disorder where likely, and when a substantial police presence could only be achieved by calling policemen of their rest days and gi ve birthing large sum of overtime. The police authority were, therefore, entitled to be paid.When the complainant is bound by an existing contractual duty to the defendant There is no consideration if all that the plaintiff does is to perform, or to promise the performance of, an obligation already imposed upon him by previous contract amongst him and the defendant is illustrated by a group of thesis in the first half of 19th century. In this case the defendant where a firm of structure contractors who entered into a contract for the refurbishment of a block of 27 flats. They sub contracted the carpentry regulate to the plaintiff for 20,000.Although there was no formal show to this effect, the plaintiff was paid money on account. After the contract had been running for some months and the plaintiff had finished the carpentry at 9 of the flats and done some preliminary work in all the rest, for which he had received some 16,200 on account, he found that he was in financial di fficulties. This difficulties arose partly because the plaintiff had underestimated the cost of doing the work in the first place and partly because of faulty supervision of his work men.The plaintiff and the defendants had a meeting at which the defendants agreed to pay the plaintiff a further 10,300 at a rate of 575 per flat to be paid as each flat was completed. The plaintiff carried on work and finished some 8 further flats but only 1one further payment of 1,500 was made. The plaintiff stopped work and brought an action for damages. The defendant argued that they were not likely as they had simply promised to pay the plaintiff extra for doing what he has in any case obliged to do, that is to finish to the contract.The Court of Appeal might maybe live found consideration in what Russell LJ described as the replacement of a haphazard method of payment by a more formalised scheme involving the payment of the specified sum on the completion of each flat since it was clear that t he under the original contract there was no get agreement for stage payments. 3. Composition with creditors It has long been a common practise for the creditors of an impecunious debtor to make an arrangement with him where by each agrees to accept a stated percentage of his debt in full satisfaction.The search for a sufficient consideration to support so reasonable an agreement has caused the courts much embarrassments. It would appear at first sight to fall under the ban in Pinnels case, and such was the view adopted in 1804 by Lord Ellenborough. Two alternatives suggestions have been proffered. The first was the second thought of Lord himself. There was consideration for the composition, he suggested in 1812, in the fact that each individual creditor agreed to forgo part of his debt on the hypothesis that all the other creditors would do the ame. A moments reflection will expose the weakness of this argument. Such a consideration would, no doubt, suffice to support the agreemen t as between the creditors themselves. But, if the debtor sought to rely upon it, he would be met by the immediate objection that he himself had furnished to return for the creditors promises to him, and, as already observed, it is a cardinal rule of the law that the consideration must move from the promisee.A second solution is to translate that no creditor will be allowed to go behind the composition agreement, to the prejudice either of the other creditors or of the debtor himself, because this would be a fraud upon all the parties concerned. The solution was suggested by Lord Tenterden in 1818 and supported by Willes J in 1863, and it has since won general approbation. But it is frankly an argument ab inconvenienti and evades quite a than meets the difficulty.Where the plaintiff is bound by an existing contractual duty to a third party When the plaintiff performs, or promises to perform, an obligation already imposed upon him by a contract previously made, not between him and the defendant, but himself and the third party. The question whether such a promise or a performance affords suficient consideration has provoked a voluminous literature more generous, indeed, then the practical implications would seem to warrant. In a case mentioned here the defendant agreed to pay money to he plaintiff in return for the plaintiff promise (a) to execute a separation deed and b)to pay his debts to a third party. The promise to execute the separation deed raised questions of public policy but was held good consideration.
