Waste Elimination - Coursework Example The system uses a two-way approach focusing and driving both customers, internal as well as external. The basic purpose of Lean Manufacturing is to eliminate waste at all levels of production including the product design, factory management, supplier networks and customer relations. Its basic aim is to reduce the overall human effort, reduce the inventory storage, taking less production time and less space to become responsive to customer demands while also producing high quality products in the most economic and efficient manner. In this context waste is defined as anything that customer is not willing to pay for (Ramnath, et al., 2010). In the current environment, no company in production or engineering can achieve success without the incorporating the lean production methods in their systems. The Lean production methods or the TPS system given by TaiichiOhno serves as a strong base for competitive, successful and modern flow of materials. (Berlec & Starbek, 2009) In the manufactur ing process any activity that doesn’t add value to the product is considered to be waste. Hence it is important for the company to identify the waste in the processes and to find out ways that can be used to eliminate these wastes in order to achieve success and to remain competitive. The seven types of wastes include(Hutchins, n.d.): 1. Overproduction - Producing more than the customer requires 2. Waiting - Excessive machine time/downtime, or waiting for upstream information/advice 3. Transport – transportation of goods over long distances 4. Over processing – producing more than what is required by the customer 5. Inventory – Parts or stock which are not currently being worked on and are stored 6. Motion – the search for tools and other accessories 7. Defects – working out the defects In addition to these other categories have also been added to this which includes: Raw material and energy Damage to the environment Background Honda motor c ompany was established in 1948 by Soichiro Honda with its core emphasis on competing in the Japanese motorcycle industry. However in the year 1962, Honda manufactured its first car and by the year 1995 the Honda group was manufacturing, selling, and repairing motorcycles and cars as well as other power products. Honda was the first Japanese company to establish its operations in US. Its first plant for producing motorcycles was in America, outside Marysville, Ohio in 1979. The company expanded its Marysville facility so as to gain localization which included: Production, products, profit and management. (Maxwell, et al., 1998) Environmental Policy and Management In the early 1990’s political pressure was built up concerning the environmental issue therefore to address these Honda strengthen its commitment to environment and its protection by adopting a Global Environmental Declaration and also by addressing the environmental issues on a global level. The Global Environmental Declaration dictated how each Honda company should strive to evaluate the impact of their activities to the environment, and to design the products in such a way that can reduce the impact of use and disposal, can help in recycling and conservation of energy and resources and to promote awareness in the employees and society. Honda adopted a policy that emphasized on the responsibility of

Globalization Term Paper Example | Topics and Well Written Essays - 1750 words

Globalization - Term Paper Example assumption that globalization entails economic integration, exchange of knowledge, as well as interdependence of political and legislative decisions of world countries. Among the latest definitions of globalization is that of Al-Rodhan, who concludes that â€Å"globalization is a process that encompasses the causes, course, and consequences of transnational and transcultural integration of human and non-human activities† (Al-Rodhan 5). Therefore, it can be said that globalization is the process which makes integration and communication between countries, nations, businesses and individuals easier and less dependent on political or territorial constraints. This means that state boundaries or long distances play a less important role in communication and cooperation of nations. As countries become more integrated, they become more interconnected and interdependent in many aspects of their operations. Technological developments in transportation and communication have made it pos sible for world countries and people to become closer. The Internet, in its turn, has sped up and intensified the process. Availability and relative cheapness of Internet access around the world has diluted the states’ boundaries having allowed more people and businesses to work internationally. This has made different types of globalizations become more distinct and powerful. Among the major types of globalization are economic (financial), socio-cultural, and political (Dreher, Gaston, and Martens 2). Economic and financial types of globalization are among the most discussed ones because they are related to interdependence of world economies, increased flows of international capital and cross-border trade of goods and services (Shangquan 1). Technological advancements in transportation and... The intention of this study is globalization as a very complex process that touches all the spheres of people’s lives. Consequently, just like the majority of internal processes of each country, globalization evokes both positive and negative consequences. On a positive side are, definitely, the spread of technologies, free trade, and an increase in exchange of commodities between the countries. Globalization brings economic and financial development to less developed countries, and new business opportunities to the whole world society. Still, it cannot be said that globalization can be made to work for all, because advantages in some aspects bring disadvantages in others. For example, the spread of communication and Internet technologies has allowed businesses to outsource jobs from poorer countries to take advantage of the lower wage rates. As a result, home country professionals either lose their jobs or have to work for lower salaries. Similarly, outsourcing of business pr ocesses, while is a great driver for India’s economy, has lead to displacement of some service-sector jobs in developed countries. Globalization diminishes the importance of borders and, supported by the Internet, allows for free movement of information. As a result, it is becoming more and more difficult for governments to control and suppress information they prefer to restrict. The Internet even provides large companies with opportunities to show self-governing behavior.

The HR policies in multinational companies

The HR policies in multinational companies A critical issue faced by host-country nationals with respect to HR management is the degree to which Multinational Companies (MNCs) include parent HR policies as part of global HR policies (Lawler, 1999). This greatly depends on the company structure, market structure, and its global presence. However, HR policies are affected by various factors that these MNCs need to incorporate once they start operating in host countries. A major factor because of which MNCs incorporate these factors in their HR policies is due to culture; many of the HR policies of MNCs take into account the culture of the host country of which gender is an important factor (Lawler, 1999). If gender discrimination is not appreciated in the host country, companies will need to formulate HR policies accordingly, whereas in countries that discriminate on the basis of gender and is culturally and socially acceptable, then MNCs may or may not formulate policies based on it as then it would be the parent companies discretion as to how they would want to approach the matter keeping in mind the company values and objectives. One way to study the culture of countries and understand how important the issue of gender discrimination is is by examining factors using Hofstedes cultural dimensions. These dimensions are power distance, individualism/collectivism, masculinity/femininity, and uncertainty avoidance (Hofstede, 1991). To study the extent to which gender issues affect the HR policies of MNCs, it is more appropriate to look at individualism/collectivism rather than masculinity/femininity; gender issues in the context of HR is more about the degree to which women liberalisation is prevalent in the country rather than how masculine or feminine the culture of the country is. Individualistic cultures focus more on personal accomplishments hence those cultures are more likely to influence MNCs to formulate gender bias-free HR policies when operating in that particular country; the study reveals that in individualistic countries, HR policies of MNCs do not discriminate people on the basis of gender (Lawler, 1999). Globalization The world today has become highly dynamic and competitive; globalisation has become the catchphrase in the business world where policies and strategies are developed as per global competitiveness (Joynt and Morton, 2005). Due to this factor which affects revenue generation and profits of organisations greatly, multinationals try and formulate bias-free policies when it comes to gender. A research was conducted to compare the HR practices in insurance companies of Indian and multinational companies; results showed that Indian companies discriminated salaries and job positions on gender basis; however, in multinationals, this practice was not evident (Kundu and Malhan, 2009). Today, what companies are looking for is a competent skilled employee who is the right person for the job; jobs are not restricted to males or females, rather they are about the right person. Hence, it can be concluded that in multinational companies gender does not affect HR policies if organisations are revolvin g their strategies and corporate objectives around globalisation and are trying to gain corporate and competitive advantage on a global level. European Cases The European Foundation for the Improvement of Living and Working Conditions (2005) studied a number of European corporate cases that included the HR practices of companies operating in Europe. All these examples focus on how important gender has been in being a part of HR policies and finally in achieving corporate objectives. Grupo Texto Editores is a Portuguese company that realised the importance of gender equality and made it a part of its HR policies as the management felt that gender balance was extremely important in order to make the company competitive; this HR policy of the company has won it the Gender Equality and Quality Award by CITE in 2000 (European Foundation for the Improvement of Living and Working Conditions, 2005). According to Mr. Luis Pedro Nunes, Head of Global Human Resources Operations of the group, the companys success is largely due to the gender policy of the group; the HR policies have been built on the principle of hiring the right people and hence it automatically maintains a gender balance in the organisation. Another case that the European Foundation for the Improvement of Living and Working Conditions (2005) has studied with respect to gender and HR policies is that of Nestle. Nestle France has faced major challenges with respect to gender imbalances in the company which has affected its reputation globally. The multinationals HR policies in recruitment and other areas such as training are seen to be highly discriminatory by the union; women are not promoted to senior positions, they are not sent on training, and much of their demands are not addressed by the senior management. This resulted in unbalanced salary structures between men and women, limited training opportunities for women, and very few promotions for women to senior levels. French legislation has passed considerable bills that force firms not to discriminate on the basis of gender; companies with a workforce of over 200 are required to even have equality commissions. Nestle France however falls short in displaying gender quality and hence falls behind other global competitors such as Danone. The management did get concern about the discriminatory practices in the company and hence conducted a survey which showed drastic discrimination against women. Nestle France consequently made changes in its HR policies to tackle this problem and by 2003 the company had female managers in high positions and a female member on its board. Nestle has also put certain mechanisms to ensure gender equality as part of its global HR policy. Nestle France clearly illustrates an example whereby how gender-biased HR policies can affect the reputation of companies. If companies do not address these issues, they fail to gain competitive advantage over other firms, just like Nestle France has lost it to Danone. The Case of Norway Gender greatly affects the reputation of countries because of which they continue including it in HR policy formation. Norway has been given the status of forerunners regarding gender equality in Europe; it is also among the top countries that promote female participation in the workforce. However, the government of Norway, even after these statuses regarding gender equality, realised that the companies operating in Norway did not have much representation of women in leadership positions. To counter this issue, the government encouraged companies to formulate HR policies that give more opportunities to women and increase their role in leadership positions. Another reason they formulated such policies was because the country realised that they are wasting the 50% female population of the country and were not utilising these resources when females could contribute to the society in similar ways as men could. The Ministerial Intervention at the EU Informal Ministerial Meeting on Gender Equality (2008) discussed gender bias-free HR policies as a precondition for building competitive organisations in the global corporate world. The MNCs also saw women as the future and a sign of modernity for them which encouraged them to formulate gender-friendly HR policies. Due to these reasons, the gender balance requirement was set in Norway which was at 40% in all companies. This has proven successful across Norway; hence, it can be concluded that gender does affect HR policies in multinational companies and other companies, especially when countries, as a whole, realise the strategic importance of gender bias-free policies. Gender Pay Inequalities One of the major reasons for gender-based discrimination in MNCs is pay (Blau and Kahn, 2007). Many labor force statistics reveal the existence of gender pay gaps. In the USA, an average woman had to work until April 2008 at the present gap rate in order to earn what an average man earned towards the end of 2007 (The National Womens Law Center, 2008). Likewise, in the European Union, there are a number of MNCs being biased in their HR policies where the matter is related to pay structures. An average full time working woman in the UK would miss approximately  £369,000 in her working life (BBC News, 14.11.2008). At times, women do not even realise that they are being discriminated against on the basis of pay structures; in some cases, women may be aware of the discrimination as per company HR policies; however, they might not consider pay disparities as important when compared to other dimensions of work (Khoreva, 2009). The Global Gender Gap Index Gender, being a discriminatory factor in global HR policies, has become so important in todays globalised world that a need for a Global Gender Gap Index has arisen. Gender greatly affects the HR policies of MNCs, consequently creating gender gaps. The Global Gender Gap Index scrutinises the gap between women and men in four basic yet extremely important areas: economic participation and opportunity, educational attainment, political empowerment and health and survival (The Global Gender Gap, 2008). It can be concluded form the report that the gap has been widening globally as the number of countries with widening gaps in 2006-2007 was 24, where as in 2007-2008 the number was 41 (The Global Gender Gap, 2008). Although countries with narrowing gaps are more than countries with widening gaps, the percentage of improvement is decreasing over the years; from 91% in 2006-2007, the rate has gone down to 87% in 2007-2008 (The Global Gender Gap, 2008). Hence, it is evident that MNCs globally are not addressing gender discriminatory issues in their HR policies as the Global Gender Gap Index is continuously increasing. Conclusion The discussion throughout this paper focused on different factors and reasons that affect HR policy formation; policy formation is not only based on corporate philosophies that promote gender equality or favor women, however there are multiple ways by which gender affects HR policy formation in multinational companies. Gender equality greatly affects HR policies in multinational companies primarily because of the global village the world has shrunk into. The need of the hour is the integration of the entire world where gender plays an extremely important and crucial role. Gender equality has become a prerequisite in developing multinational companies into highly competitive organisations. The world has become so competitive that in order to survive, companies will not just have to include women in its workforce but also invest in their training and development in order to help them reach leadership positions in top management. If companies favour either of the two genders, they will never be able to achieve success levels that organisations having gender bias-free HR policies might have achieved or will achieve in the future. Incorporating gender as a major factor in formulating HR policies especially in multinational companies motivates the local population of the host country. It helps bring the youth of the country, both men and women, together in contributing to society and more by being part of these companies. Finally, equal opportunity policies should be formulated as HR policies of multinational companies so that these companies are able to develop trust between the people of host countries they are operating in and the MNCs as that will facilitate the entire process of global communication and make the world a better place to live and work in.

Feminism Essay -- Womens Right, Equality

The past century saw women in Britain gain control of their fertility, acquire access to education and establish their status as equal citizens. The British social order came a long way from 1890s when women in Britain were legally restricted to the point they could not enter a contract, own property or have parental rights; unmarried women were challenged by society and pressured in to marriage (British History Oxford, 2007).The women’s rights and suffrage movements in the period between 1832 and 1918, which is known as ‘The first feminist wave’, aimed to challenge the idea of women being the inferior sex and demanded equal rights. This ‘so called’ first wave ended with the ‘Royal Assent to the Representation of the People Parliament Act’ being passed in 1918, which granted women the ability to vote and recognised females as equal citizens (Fraisse, 1993). Following work will assay the position of women in today’s society and barr iers that prevent gender equality. The focus will be on the conflict between feminist ideals, assumptions and demands behind what known as feminism. Feminism has evolved dramatically over time, which makes finding a widely accepted set of feminist ideas an impossible task. However, Webster’s dictionary (2007, p230) defines feminism as a theory of the political, economic, and social equality of the sexes. Therefore, feminism is based around the idea of men and women being equal. On the other hand, feminist is also defined as ‘an organized activity on behalf of women's rights and interests’ (Webster 2007, p.230). This highly ambiguous definition suggests that any socially or politically active woman can be considered to be a feminist, so the ideas of feminists do not always coincide with the philosophy o... ...en’s favour. Therefore, it is extremely difficult to determine what gender receives the larger income over a lifetime. With this in mind, modern feminism appears to be aimed at total equality, where every adult receives same wage and employers are controlled by the government. The feminist philosophy, on the other hand, preaches equality purely in legal and political rights. A number of conservative feminists believe the battle for equal rights was won when in 1928 women were enfranchised (British History Oxford, 2007). It caused social transformation in Britain and liberated women. This philosophy is relevant in modern society because it can be beneficial in any country where women experience hard ship due lack of legal equality. Further legislation aimed at improving equality in the UK needs to consider possible side effects, and should promote equality for all.

Formative and Summative Assessment Essay

Assessment is a term that includes all of the various methods used to determine the extent of an individual’s achievement. In teaching and learning situation, assessment refers to the methods used to determine achievement of learning outcomes. Similarly in professional contexts, assessment is concerned with the achievement of professional standards or competence.(Aranda & Yates,2009). Assessment also provides a number of major benefits including: †¢ Grading: assessment may be used to define achievement and to measure the students’ preparedness for professional challenges. †¢ Motivation: assessment may focus on real learning by creating an opportunity that carries with it the rewards of completion or grades. †¢ learning process: assessment activities can guide individuals to learn and relearn subject content efficiently. †¢ Feedback: assessment provides opportunities for individuals to monitor the quality of their performance and identify areas for improvement. PURPOSE OF ASSESSMENT It is easy to become so immersed in the job of teaching that we lose sight the exact purpose of a assessment. There is then the possibility that we are overlooking another form of assessment which might be more appropriate. We actually assess students for quite a range of different reasons – motivation, creating learning opportunities, to give feedback (to both students and staff), to grade, and as a quality assurance mechanism (both for internal and external systems). Because all too often we do not disentangle these functions of assessment, without having really thought it through assessments are frequently trying to do all these things, to varying degrees.(Oxford Brookes University,2011). In fact it is arguable that while it is desirable for assessments meeting the first three of these functions to be conducted as often as possible, the final two do not need to be done anywhere near so frequently; it is simply important that they are done somewhere. The implications of this are that while an essay question, where all the answers are double marked and the marks count towards the students’ final grades, may fulfil all these functions, for all assessments to be this rigorous would be prohibitively expensive in staff time, while a peer-assessed seminar presentation, which does not count towards the students’ final grades but is simply a course requirement, could fulfil the first three functions and may not even require a tutor to be present. FORMATIVE ASSESSMENT Formative assessment is typically contrasted with summative assessment. The former supports teachers and students in decision-making during educational and learning processes, while the latter occurs at the end of a learning unit and determines if the content being taught was retained.(Wikipedia,2013). Formative assessment is not distinguished by the format of assessment, but by how the information is used. The same test may act as either formative or summative. However, some methods of assessment are better suited to one or the other purpose. CHARACTERISTICS OF FORMATIVE ASSESSMENT During formative assessment, learning is the shared goal of both teacher and student and alterations to the teaching and learning process take place as needed to further the goal. This allows both the teacher and the student the opportunity for assessment and improvement as an ongoing process instead of an end product. Formative assessments are assessments for learning, rather than assessments of learning, according to the Association for Supervision and Curriculum Development. Focused Formative assessments are focused on the learning process as well as the learning progress. While other assessments may only focus on the end result, formative assessments check the students progress consistently so that adjustments can be made to reach learning goals. Ongoing A formative assessment is consistent and ongoing throughout the learning process. It differs from assessments that focus on the end result. Ongoing assessments give both teachers and students the chance to make adjustments to teaching and learning strategies so learning ultimately takes place. Immediate While other forms of assessment focus on the end result, formative assessments provide immediate feedback to both teachers and students due to ongoing assessment practices. The immediate feedback teachers and students experience can be used to motivate and further learning. LIMITATIONS OF FORMATIVE ASSESSMENTS Although offering many benefits, effective formative assessment can be difficult to achieve at scale. It may be logistically impossible to provide detailed descriptive feedback for each student in a large class. Even with a smaller number of students to deal with, formative assessment is time-consuming as it requires significant, ongoing dedication and effort from the teacher to sustain. This is especially true when combined with the summative assessments teachers are required to complete. The layered accountability chain in education — student to teacher, teacher to school, school to district, etc. — creates systemic pressure for student performance to be objectively and comparatively measurable at each level. Formative assessment, by definition, doesn’t easily provide that kind of accountability. This explains why, although the advantages of formative assessment have been repeatedly articulated since the distinction between it and summative assessment was first made in 1967, empirical studies continue to show that very few teachers consistently make use of it in actual practice. SUMMATIVE ASSESSMENT Summative assessment measures attainment and allows for the recording of the learning progress. It usually takes the form of tests and examinations, though it is becoming increasingly common for summative assessment to include other tasks such as a project completed during the school year. This move away from assessments based on a single examination gives learners the opportunity to perform to the best of their ability. Not all learners perform well under examination pressure. Furthermore,examinations do not always lend themselves to eliciting the range of language structures and uses that have been the objective of teaching CHARACTERISTICS OF SUMMATIVE ASSESSMENT The results of summative assessment allow us to determine the degree to which learners have attained specific learning objectives. Such a decision may have an important consequence on learners’ future prospects. It is therefore crucial that not only is the assessment valid, but that the results obtained are reliable. Validity relates to whether the assessment tasks assess what they intend to assess. Reliability, on the other hand, refers to the results obtained and whether these would be the same if the same learners took the assessment on another occasion provided that no further learning had taken place and regardless of who marked the assessment if more than one person was involved in the process. (Summative assessment,2005). Whether summative assessment is norm-or criterion-referenced will be determined by the purpose of the assessment. If we need to select the best candidates to, for example, continue with their education, then norm-referencing would be appropriate. However, if we are interested in whether candidates have mastered certain skills, then we would not get the required information through norm-referencing.(Meason) For example, when assessing airline pilots we are interested in whether they can fly a plane safely to a very high level of proficiency. Knowing which trainees were the best would not suffice since it is possible that no trainee of a given group would have reached the required standard to safely fly a plane LIMITATIONS OF SUMMATIVE ASSESSMENT Students can face anxiety in preparation for a test, an anxiety that grows as the perception of the test’s significance grows. Summative tests advise schools to commit to prolonged pretesting procedures and preparation classes, which can increase student anxiety.(Spiral). In addition, some students simply do not test well, and the result is a testing procedure that fails to adequately assess the real talents of individual students, while a formative assessment would allow a teacher to evaluate these conditions and better assess a student’s ability Summative assessments fan have an overall negative impact on student self-esteem, resulting from the perception of inferiority that standardized tests can give test-takers. Students who perform poorly on standardized tests were found to suffer from lower self-esteem in situations where these same students had not previously exhibited signs of self-esteem problems.(Boggiano,1992). Even students who perform average or well on standardized tests can suffer from the failure to meet their own higher expectations. The result can be a reduction in educational motivation.(Hammond). EXAMPLES OF FORMATIVE AND SUMMATIVE ASSESSMENT FROM TEACHING AND LEARNING PERSPECTIVE CONCLUSION In my view,both types of assessments are better,that is a balanced assessment.A balanced assessment system in one in which a variety of assessments are used for a variety of purposes and communications about results facilitates student involvement and ownership of learning.Formative assessment can be vital importance in helping the teacher and students determine the quality of learning that is taking place and can allow them to forecast the results of summative tests some time in advance of the summative testing.Such results can be used as the basis for altering the teaching learning situation early enough to change the immediate as well as alter the forecast. Learning is a process which can be observed and evaluated as it is taking place.Formative evaluation can be used to make the process more effective long before the summative evaluation.Recognition of the interaction among formative evaluation teaching and learning and summative evaluation can do much to improve teaching and lea rning before it is too late.

Beginning Thinker Essay

I would say that I am a beginning thinker, I have control of all of my own personal thoughts I know that I am not always correct most of the time during each step of the thought process but I feel that I have a really good understanding of how to fix some of the issues that I have when in thought. Although some of the conclusions that I come to either workout for the short-term or long-term issue or have a tendency to be the opposite of the outcome that I was hoping for. I sometimes catch myself making a quick decision without fully thinking through the whole concept or the outcome that it will have on the issue that I am working on. I think that I can fix this by not jumping to conclusions when I am in thought, having a system to make sure that I get to the best possible outcome is something that I think I will implement going forward just to make sure that the outcome for my decision is one that I will be happy with and not regret. Critical Thinking I would say that my current critical thinking skills could be a little better, mainly because I have a tendency to over think when I am trying to come to a resolution to a specific problem. My strategy mainly consists of me thinking about the different ways that I can get to the best outcome but I also have a tendency to throw in my own assumptions or bias when coming to a resolution, this is what I feel makes me to either make an incorrect decision or make a decision based off only what my own personal feelings are towards the situation. A way that I feel I can develop better skills as critical thinker is to take all bias out of my decisions and make sure that what I do is not only best for me but will also help me keep on a path to reach my ultimate goal.

The methods Miller uses to create dramatic tension Essay Example

The methods Miller uses to create dramatic tension Essay Example The methods Miller uses to create dramatic tension Paper The methods Miller uses to create dramatic tension Paper Death of a Salesman is a fantastic example of a continuation of increasing Dramatic Tension. It is created by such methods mentioned in the title and further strengthened by the jumps between past and present. Miller also uses the continuing theme of symbolism to strengthen the tension of the play. The lasting impression is one of slight confusion, but this too aids the suspense as Willy Loman, the focus character of this tension, continues to lose his grip on reality and finally then, his life. Throughout the play the audience are invited to second-guess Willys next actions or attempt to link his present as a result of past events. The other characters in the play are also equally vital in allowing Miller to create such heightened dramatic tension. Often it is through their silent interactions, such as the complexity of relationships that exist only in thought or feeling. While the audience is aware of these unspoken family rifts, they are rarely exposed and this can create heightened dramatic tension. Linda then, is a character that we learn directly very little about. It is only through her interactions with her family that her nature is revealed, and this sense of mystery adds to the dramatic tension. Where uncertainty exists, suspicion can grow; the audience may sometimes question Lindas motives due to a lack of understanding into her character, creating dramatic tension. The audience cannot fathom why she stays with Willy and her dysfunctional family. Is she accepting her subordinate position as part of the nuclear family in order to hold it together? Or is she limited by her own personal inadequacies that prevent her from standing independently? Millers creation of a character shrouded in ambiguity allows extensive scope for dramatic tension. In fact Miller claims that he had no choice as far as the creation of Lindas character because A woman who was thinking of herself more would simply not have been there one morning, or else she would have put up such a fight so as to crush him [Willy]. This indistinct character of Linda has an effect on her relationship with Willy. From the beginning of the play, her interactions with Willy are almost unnaturally devoid of confrontation, instead she seems to be constantly looking to mother and appease her husband. We see constant references in the stage directions to the infinite patience of Linda. A constant dramatic tension hangs over their relationship, as Willy breaks down and Linda is increasingly challenged by his behaviour and distressing mental state.

War Dehumanization in All Quiet on The Western Front Essay Example

War Dehumanization in All Quiet on The Western Front Essay Example War Dehumanization in All Quiet on The Western Front Paper War Dehumanization in All Quiet on The Western Front Paper Essay Topic: All Quiet On the Western Front War Dehumanization in All Quiet on The Western Front BY Itmes123 War Dehumanization If you think of humanity as one large body, then war is like suicide, or at best, self mutilation( Jerome Crabb). Paul B? ¤umer, the protagonist of All Quiet on the Western Front by Erich Maria Remarque fulfills his understanding of Jerome Crabbs quote after experiencing everything war has to offer. In the novel, Paul truly experiences what being in war can physically and mentally do to not only a man, but their families as well. It is apparent that Erich Maria Remarque had Paul B? ¤umer face various orrifying situations while at the front to make a powerful statement against war and everything associated with it. Throughout the book, Remarque uses implicit statements to help prove his argument in a myriad of ways. The statements Remarque includes in the novel cohere with one another to show that war dehumanizes the soldiers who choose to enlist into it. Through the implicit language and arguments used, the dehumanization effect war brought upon the soldiers is illustrated as an unbreakable force that takes no pity on the soldiers at the front. It greatly affects the soldiers physically, mentally, and even psychologically. Erich Maria Remarque shows that war has a dehumanizing effect on the men even to the point of being compared to savages by using point of view, literary devices and imagery. By applying the points of view of the distinct characters in his novel, Remarque is able to implicitly make the argument that war dehumanizes the soldiers in every way possible. Because of the usage of point of view, the argument trying to be proven is seen through a clearer outlook since a single characters personality does not affect the argument of war dehumanizing the men. Conventional human characteristics, for xample the significance of education, have seemed to be lost completely due to war. When discussion arises between Paul and his comrades about their aspirations after war, the men come to realize that they have forgotten most of what their schoolmaster Kantorek had taught them back in school which was really not that long ago. Paul even considers the school lessons they received back as civilians to be rot(86). The word choice Paul uses sort of gives off a supercilious tone on education. Pauls tone on the topic illustrates that he sees little or no value in the education he learned from his schoolmasters. Obviously, education is seen as an extremely important part of humanity of the soldiers but since Paul is devaluing education, he is essentially devaluing humanity as well. Adding onto Pauls depreciation of education at the front, as Leer, one of his closest comrades is killed, Paul comes to the understanding that being such a good mathematician at school served Leer no good while fghting on the front (284). The realization he made is that war does not take pity for people who are well educated. Paul feels that war cares nothing of education since Leers mathematics skills were not able to help him survive the ombardment and therefore, the education used on Leer served of very little use for him since ne was not able to survive the wrath ot war. This experience displays to Paul that only instinct can help to survive being at the front. Solely using instinct to survive is a characteristic only vital to animals and because Paul exhibits this characteristic, Remarque is implying that all soldiers act based off of instinct.. It is in essence showing that the soldiers in way are at a level comparable to various animals. Yet another point of view Remarque incorporates to illustrate animal like ualities in the soldiers is that of Albert Kropp. In this instance, Kropp is badly hurt with an amputated leg. He no longer sees the value of enduring the strong pain as he tells Paul that he will shoot himself the first time he can get a hold of his revolver(261). By devaluing his own life, Kropp has shown to the readers that war has destroyed his own humanity since life is one of the most important values in humanity. Without the virtue of humanity, Kropp and many other soldiers that find themselves in similar situations can be compared to animals. The points of view from Albert and Paul all are brought together to show the dehumanization effect war causes since the men are no longer caring for their humanity. Also, literary devices integrated in the novel cohere with each other to furthermore show how the soldiers at war become less and less human everyday. As the soldiers fall in line for breakfast to receive their normal amount of rations, the sergeant cook is shocked to see that only 80 of the men survived the heavy attack from the previous day. He unwittingly made enough food for the 150 men but because nearly half of them had died, the ook finds himself with an overload of food. Because of the massive surplus, the soldiers in line for breakfast plead their case to the cook that they should receive double rations for the day. At first, the cook is hesitant to comply with the soldiers orders thinking Eighty men cant have what is meant for a hundred and fifty'(5). The literary device shown here is irony as after persuading the cook for double rations, the Second Company which came back 80 strong has no difficulty consuming all of the leftover food meant for the other soldiers who were not as lucky to survive. After eceiving and consuming the extra food, the soldiers showed no remorse of the fact that they were eating their fellow dead soldiers breakfast. The only emotion they felt was satisfaction in their bellies. The men usually receive minimal food at the front so they quickly snap at the opportunity to receive an extra ration despite it being meant for the dead soldiers. This quality the men portray is one similar to animals as animals also snap at any opportunity to get food even if it is at an expense of another animal. They only think of what they can do for them to be better off and in this case, he soldiers are doing the same. Another literary device Remarque uses to confirm his argument is symbolism. As Paul and his comrades crowd around Kemmerichs bed at the hospital, they notice that Kemmerichs leg has been amputated. Out of the group, Kemmerich has the most comfortable boots and Muller takes note of that. Considering the fact that Kemmerich will no longer be able to wear the boots, Muller desperately wants them to replace his worn out uncomfortable boots. At first, Paul wanted Kemmerich to keep and die with the boots still in his possession but he omes to realize that only the facts are real important for [them], And good boots are scarce(21). Since Kemmerich is close to death, Paul thinks of the value of the boots and where they are most needed without the realization that they are a prized possession of his dying comrade Kemmerich. War has really dehumanized the men as their value system nas changed tor the worse and the boots represent now much more they care for things that could make them better off rather than the life of a good friend. All in all, the literary devices used in the book help make a valid claim hat war has a dehumanizing effect on the soldiers. By applying imagery, Remarque shows the soldiers in war are dehumanized to a level that can be compared to animals. The soldiers find themselves resorting to their animal like instincts to help stay alive which make them lose all human characteristics by fighting in the war. Following Pauls leave from the front, he serves some time as a prison guard watching over the Russian prisoners and unintentionally compares the prisoners to animals describing them as meek, scolded, St. Bernard dogs and they seem nervous and fearful(189). St. Bernard dogs are defined as generally very large working dogs originally bred for rescue. The word choice of meek and scolded certainly do not match the definition of St Bernard dogs as rescue dogs have to be assertive and praised. Paul is hinting to the fact that because of the harsh conditions the prisoners are forced to endure, they have been ever since going through a long stint of dehumanization. The Russian prisoners also slink about [the] camp and pick over the garbage Slinking around the enemy camp suggests that the prisoners are trying to scavenge any left ood in a stealthy manner trying their best not be noticed by the others. This tactic is very similar to how various animals capture their prey so war has actually animalized the prisoners. Also, the Russians result to picking through garbage cans to try and find leftover bread crumbs. Searching through garbage cans for food is certainly the last resort for food but war has dehumanized the men to the extent where all they care about is surviving. If it means eating out of the garbage can, they will do so. These two instances show how animalistic war can make men become. By ncorporating character point of view, literary devices and distinct imagery, Remarque shows that war has not only dehumanized the soldiers but animalized them as well. Remarque is able to implicitly show Just how dehumanizing war can be to anyone that is absorbed into it. It truly destroys the humanity in all men that comes in its way. Time and time again, Remarque pleads his case of how fighting in war and being at the front can over time make a man less than a human being and closer to an animal due to the loss of many values of humanity. His argument in the novel is quite specific and strong but it is certainly valid.

Business Regulation Law

When an organization do not comply with the state and federal regulation the company can face fines or become caught up in major litigation, costing the company major expenses. In this memo I will identify common tort and risk found in the organization of Alumina, and describe different measures to manage risk. Some common torts found at Alumina are negligence, defamation/slander/libel, Freedom of Information Act (FOIA), and strict liability is tort liabilities uncovered. Alumina Violation Alumina is an aluminum maker base in the United States and has operation in eight countries. The aluminum maker is on Lake Dira in the state of Erehwon. Alumina is under the jurisdiction of region six under the Environmental Protection Agency. A few years ago Alumina was found in violation with the Environmental Protection Agency for environmental discharge norms in an Environmental Protection Agency compliance evaluation. The PAH levels were above prescribe limits. Alumina was order to clean up the problem in which they complied too quickly. Because of this incident Alumina has maintain a good compliance record. Recently a resident name Kelly Bates claims that Alumina continuous contamination of Lake Dira with pollutants. Bates threatens to file a suit against the company for punitive damages and recovery damages. She believes that the incident that occurred several years ago is the cause of her daughter’s leukemia. Tort Liability A tort is a â€Å"civil wrong that is an interference with someone’s person or property such that an injury results† (Jennings, 2006, p. 367). Torts can be categorized as intentional torts, torts of negligence, and strict liability torts. Intentional torts are those that result in a harm not accidental. Torts of negligence are accidental harms that result from a failure to act appropriately in a given situation. Strict liability torts assign absolute liability and offer very few defenses. Defamation of Character A company or a person reputation is a valuable asset. The tort of defamation of character requires that a plaintiff prove that: the defendant made an untrue statement about the plaintiff or the statement was intentionally published by a third party (Cheeseman, 2010). Written False statements are referred to as libel and verbal statement are referred to as slander. Bates made a libel statement in the newspaper about Alumina and the violation that occurred years ago. This defamation can have a negative effect on the company. Alumina can lose business with a bad reputation and once the reputation has gone sour it is hard to reclaim the good name. Freedom of Information Act A local news reporter and Kelly Bates approached the EPA to obtain environmental audit reports that documented Alumina violation of the Clean Water Act. Bates requested the documents under the Freedom of Information Act; this act was enacted in Congress in 1966 to the American public great access to the Federal Government records (Federal Communication Commission, 2010) . The Company chooses to release partial audit information from the violation from years ago. Alumina has the right to withhold informational this qualifies under the Confidential Business Information, which is available under exemption four of the Freedom of information Act. Strict liability Negligence and Strict liability Negligence, the most common tort, is explained as conduct that falls below standards of behavior established by the law for the protection others against unreasonable risk harm (Cheeseman, 2010). In this case of negligence Bates must prove that Alumina had a duty to keep the PAH levels contained. In a case Alumina breaches that duty by not staying in compliance with the EPA regulation several years ago. Bates assumes that the consumption of the water cause the harm of her daughter to have leukemia. In response Alumina chose to conduct an independent site study for new violations. The reports come back good the PAH levels were well below the standard. After releasing a partial audit report Bates has threaten to file a lawsuit against Alumina of personal injury to recover compensation and punitive damages. Alumina negligent conduct of â€Å"serious violation of environmental laws five years ago is the cause of her daughter leukemia,† alleged by Bates (Business Regulations Simulation, 2010). The best resolution for this situation is mediation by a neutral third party, by choosing this options Alumina can provide Bates with a confidential settlement. The settlement includes that Alumina provides Bates with reimbursement of medical expenses for her daughter treatment a lump sum for future treatments and a college fund set aside if her daughters recovers from the leukemia (Business Regulations Simulation, 2010). Although tort liability is founded on intended harm strict liability is attached even though the defendant has been reasonable. In the Article titled â€Å" The American Influence on Canadian Tort Law† author Allen M. Linden states â€Å" One person may be require to compensate another for injury or damages even though the loss was neither intentionally or negligently inflicted. If Alumina had taken the case to court, the company would have been in a long litigation process costing the company thousands and even millions of dollar. The mediation process is half the cost of a court trial and there is no guarantee that the jury would agree with Alumina even though the company may have had proof that the allegation against the company was false. The jury tends to side with the victims. Preventative, Detective, and Corrective Measures In an organization it will be hard to prevent allegation against the company, but the company needs to prepare for such issues when they arise. A preventative plan should be put into place. The company should make it a priority that the employees of the company aware of the rules and regulations of the state and federal laws. The company should be aware of the competitors who have violated any government regulations and improve their process so that the company will not violate the same regulations as the competition. Health risk that may be exposes to the staff, customers, and other should be included in the document also. Conclusion Alumina has to abide by state and federal rules these laws are in place to improve environmental safety. The agency that regulates Alumina was the Environmental Protection Agency this agency enforces environmental laws. Alumina has to be aware and comply with the state and federal regulations at all-time or it can affect the business a great deal. Maintaining a positive image in the community is also important when a crisis occurs the support of the community can be a big help in determine issues. The decision mage by Alumina were wise, the company took the right approach to maintain its good name in the community and the competitive market and save cost on litigation.

Exhibition - Research Paper Example Modernism, as an imperative aspect of humanity, mushroomed and completely changed the way people were doing things. The fundamental changes underwent changed the notion and perception of humanity to the better. As a theme, modernism illustrates the past and cultural activities of the ancient people while the political and sociological theme mainly aims at presenting the mode of governance and the social life of the people during the period the artwork was done. This project shall candidly and comprehensively elucidate on an art exhibition that presents various Latin America and modern artworks, elucidate on the luster, texture, artistic impression as well as the artistic styles used in an effort to understand and link the arts to the theme of modernism. The first image in the presentation is the Cortà ©s and la Malinche, a 1923-26 art by Josà © Orozco. Four lines bound the image. At the top, it has a horizontal multi-colored line that inevitably grabs the attention of the viewer at first sight. A man and woman are drawn grabbing the body parts of each other while stepping on another man that is lying on the ground1. The black frames of the artwork candidly portrays melancholy that an audience can easily associate with the events that are going on in the image as well as the overall hardships and pains that traditions brought to a society that was striving to be civilized and adopt modern ways of doing things. It also overly uses light and dark visual artifice. Apparently, the image is a 2D artwork with an ostensibly rough texture.

In the half of th e whole ground that is the fore ground the texture is smooth which is different from the background where by the texture is rough. This connotes a difference in the whole art

Critique of the article Overpopulation threatens the environment Essay

Critique of the article Overpopulation threatens the environment - Essay Example The author brings to fore a grave problem that faces the modern world today, by seeing it in a different perspective. He points to the fact that in order to sustain the environment, human beings have to control the birthrates and take immediate action so that the environment is protected for all living beings, including humans to survive. According to him, the best means to achieve this objective is to refrain from producing more children and he considers vasectomy as a noble mission of the modern day man, in the face of the current situation. The article, published in the Opposing Viewpoints Series by Green Haven Press, deals mainly with the problem that over population of the earth by the human species has a lot of â€Å"far-reaching and overwhelmingly destructive impacts on many other animal and plant species† (Cascadia 22). The author claims that overpopulation destroys biodiversity on earth to such a extent that it will become impossible for life to sustain on the planet in the long run. The author also argues that â€Å"The entire history of humanity is one of environmental destruction and the eradication of other species† (Cascadia 22). ... Human encroachment of the environment, and the dire consequences that await them due to over exploitation of the resources, remains a topic of engaging debates across the globe. In this scenario, Cascadia attempts to reemphasize this concern, in a bid to make his audience take cognizance of the problem. The author uses the literacy devices of logos, pathos, ethos and logical fallacies as well as statistical data, to put his point convincingly across to his audience. The title itself, simple and precise, communicates the essence of the essay directly to the readers. The author then introduces the topic, referring to the impact of overpopulation and its exponential growth, by referring to the data of births and deaths. In any major mishap such the Asian Tsunami or 9/11, the death toll is much less than the birthrate in a day. By citing statistics such as this, the author illustrates a logic that controlling birth rate is a significant concern for humans in order to protect the environm ent whose resources are already over consumed. The very logic of the situation amply convinces the readers of the essay about the gravity of the situation. Cascadia appeals to the emotions of his audience by referring to historical context of human migration to different landscapes. By specifically citing the instance of the â€Å"extinction of mega fauna† in North America as a consequence of human influx in the area over 10,000 years ago, the author deftly illustrates the impact excessive human concentration can have on the environment. Again, the author’s dexterity in deploying the literary elements of pathos and rhetoric becomes evident when he refers to the example

INTERVIEW PROJECT Assignment Example | Topics and Well Written Essays - 750 words

INTERVIEW PROJECT - Assignment Example He came back recently and now runs the store that was previously operated by his father. Peter received his draft when he was 30 years old and still struggling to become a teacher in local schools. Since, this was not producing fruitful results so he decided to go on to serving his nation in that way. He strongly believes that this was Fate and that he was really nervous when he reported at the mentioned area in the draft letter (Peter refuses to give exact names, places and dates) as many able bodied people were assembled there. The first day was a general introduction to everything, most importantly understanding the ideology of going to Iraq. The second day however left everyone in cramps and aching limbs. â€Å"The only thing that let me through was the belief that this is for the greater good.† Says Peter as he had to do an extra mile since he wasn’t that tough. He does not remember his instructors clearly; all he remembers are the tenor of their voices. It was at night in the training centre when the delegated places of the soldiers were announced, Peter was assigned to go to Mosul and there he joined the 71st Cavalry regiment. â€Å"It was November when we landed there, the hot gust of wind and stench welcomed us and I realized that the training was justified for being that tough.† says Peter. ... He was good at spying, so he assisted in planting coups too. And there he experienced being a prisoner. Peter says, â€Å"I was held captive for some hours because a riot broke out between the people of different Iraqi sects and there I showed them my Mississippi spirit.† Peter was sent to combats as his fellow soldiers fell, the fight in the beginning was the toughest because they were being opposed by many as US army was also trying to strike peace-pacts with the over-thrown government. However, when matters grew worse, air raids were called for, which was the most effective one in conquering the enemy. â€Å"Life got a new meaning when I became a soldier; every act was an act of purpose and service.† says Peter. Though they seldom enjoyed because most of the time they were on duty. Apart from that, the food they usually got was below average as all of them were more used to hygienic and healthy food but resources were scarce because of the ongoing battle. The soldier s were provided with food and other essential supplies from the Headquarters but with the enemy at their heels, they had to be extra cautious. Entertainment was scarce but once in a while a fellow soldier used to sing songs of love and nobody mentioned songs of war. Once or twice, Peter tried to keep a diary but it got lost when they were moving from Mosul to Baghdad. â€Å"Never was a very religious person, but the tomb of Jonah was a historical place in Mosul and before I was transferred to Baghdad, I visited there. My stomach tingled with awe at the tomb which was elaborately decorated with enamel colors and what not. Before I could cross all the steps leading to the tomb, a lolling head, dismembered from it body

Roe v. Wade Essay Example | Topics and Well Written Essays - 1500 words

Roe v. Wade - Essay Example Justice Blackmun, writing for the majority, acknowledged that the state had an interest in regulating abortion as a way to reduce medical risk for women and to protect the lives of unborn children but argued that a woman’s right to terminate her pregnancy must be weighed against the rights of the state. As long as the fetus is not viable — the Court used an established definition of viability, which considered a fetus viable at the point it is able to live outside its mother, even if some artificial assistance is needed for it to do so — the state can only regulate abortions in ways that are reasonably related to maternal health. For abortions prior to the end of the first trimester, the Court held that the state should not interfere and should leave the decision-making to a pregnant woman and her doctor. Only for abortions during the third trimester of pregnancy, when the fetus is viable according to the Court’s definition, could the state prohibit aborti on and only then if doing so did not significantly threaten the health of the pregnant woman. Blackmun went on to state that in questions of abortion, there is no consideration of a fetus’s right to life under the protection of the Fourteenth Amendment because the Fourteenth Amendment protects only Americans who have been born. There is no Fourteenth Amendment protection for the unborn. Blackmon adds, in note perhaps to the spirit of the times, that the Court’s ruling is not intended to serve as an answer to the question of when life begins but only as a statement of the reach of the Fourteenth Amendment. Roe v. Wade remains a milestone case, setting the stage for countless arguments between those who support abortion and those who would do away with it. Though I agree with the gist of the Court’s decision — that a woman should be able to obtain a legal abortion, especially early in pregnancy — I find the legal basis for the Roe v. Wade decision a little shaky. Protecting the right to

Behavior is hereditary Essay Example for Free

Behavior is hereditary Essay The whole issue of nature and nurture is complex with potential debates centered round their influences on human development. Nature refers to the traits inherited from parents while nurture refers to the influence of the environment to an individual’s behavior (Lippa 2005, p. 26). Psychological research shows that both nature and nature have a general influence on the physical and behavioral characteristics of people. This paper seeks to explain the factors which affect nature and nurture. The nature theory holds that human behavior is hereditary. True to the theory, some traits such as blood type and eye color are known to be predominantly genetic. It can therefore be asserted that genetic variation of people affects the development and characteristics of the next generation (Lippa 2005, p. 28). Nurture on the other side holds that the environment in which an individual is brought up in influences his or her behavior. In this context therefore, it can be acknowledged that the ability of an individual to interact and conform to the societal requirements and the environment at large affects the degree to which the environment can influence the individual’s behavior (Lippa 2005, p. 28). Still to be noted here is the effect of age on the influence of nature and nurture. Inherited traits are first noticed when a child is born. As the child grows up to teenage, behavioral characteristics are predominantly influenced by the environment because of the interactive nature of people at this stage of growth as well as the ability to conform to peers and the society at large (Lerner Bearer 2004, p. 86). At adult stages, people tend to become more independent hence less influenced by the environment. At this stage therefore nature prevails but the nurture traits acquired at early stages of growth remains effective. In conclusion therefore, nature and nurture are undoubtedly influential to human development. Nature gives inborn traits while nurture takes these inborn abilities and changes them with age to fit the individual’s environment. ?

Effect of Ph and Glucose on Plant Growth

Effect of Ph and Glucose on Plant Growth Abstract: An experiment was designed and conducted to investigate the population growth of the yeast Saccharomyces cerevisiae under various environment conditions such as temperature, pH levels and glucose concentration. The research questions were then arrived as: What is the effect of differing temperatures on Saccharomyces cerevisiae population growth? What is the effect of differing pH levels on Saccharomyces cerevisiae population growth? What is the effect of differing glucose concentrations on Saccharomyces cerevisiae population growth? The different temperatures were chosen based on kinetics and each temperature differing from the other by at least 10oC, so a notable change in the yeast population to be observed. Two of the temperatures chosen were below the optimum temperature and two above and one in the optimum temperature. Based on the optimum pH levels for the growth of the yeast, certain buffers with two pH values above and two below of the optimum pH and one in the optimum pH were prepared and stored. The glucose concentration that was used in cultures which tested for the effect of temperature and pH was chosen in such a way that would enable the yeast population to grow without limitation as far as glucose is concerned. One of the options for testing the effect of glucose over the yeast growth was the absence of glucose from the culture. The other options were to halve the optimum glucose concentration and the last was higher of the optimum value. When testing the different temperatures, the results showed that there was little growth in relative low and high temperatures and very high growth in the optimum temperature (the population almost quadrupled). In the different pH levels the yeast growth was little in low and high pH levels but was increased as pH was reaching the optimum pH. In the case of different glucose concentrations, the results showed that with no glucose in the culture was a small growth; in the glucose concentration of halve of the optimum value there was growth but again less than the optimum; in the glucose concentration above optimum there was very high growth as there was in the optimum value. Chapter 1: Introduction Research Questions: What is the effect of differing temperatures on Saccharomyces cerevisiae population growth? What is the effect of differing pH levels on Saccharomyces cerevisiae population growth? What is the effect of differing glucose concentrations on Saccharomyces cerevisiae population growth? The yeast: Saccharomyces cerevisiae is a single celled fungus that reproduces asexually by budding or division. It is one of the most well studied eukaryotic model organisms in both molecular and cell biology. Saccharomyces cerevisiae is maybe the most important and used fungus in the history of the world even from ancient times because of its use in the brewing of beer and in rising of dough in bread. That is the reason why is called brewers yeast and bakers yeast, due to the use of different strains of Saccharomyces for the alcoholic and sugar fermentation. S. cerevisiae is a very good type of yeast for biological studies owing to the rapid growth (doubling time 1.5-2 hours at 30  °C), the dispersed cells and the ease of replica planting. Moreover is a non-pathogenic organism, so can be handled fearlessly with only little precautions. Also large amounts of commercial bakers yeast are available with result being an easy and cheap source for biochemical studies. S. cerevisiae has round to ovoid cells between 3-8ÃŽÂ ¼m in diameter Respiration: In biology, respiration is defined as: the process by which the energy in food molecules is made available for an organism to do biological work (Kent, 2000; p.100). It is also called Cellular respiration. This process of cellular respiration happens in every living cell as it is the only way to obtain energy in a form that will be usable for the cell, so it can carry out the functions of movement, growth and reproduction (ibid). The food in yeasts must be obtained as they cannot produce it on their own. For yeasts, a very good source of energy is sugars. All strains of S. cerevisiae can metabolize glucose (a hexose sugar), maltose and trehalose. Adenosine Triphosphate (ATP): Adenosine Triphospate known also as ATP is the form of chemical energy that cells use to carry out biological activities. Without ATP an organism cant survive. During cell respiration the energy that is found in food molecules is transformed to ATP (Kent, 2000; p.100). Types of Respiration: There are two main types of respiration that take place within a cell: Anaerobic respiration (without oxygen) and Aerobic respiration (with oxygen). S. cerevisiae can metabolize sugars in both ways, but in this research the cultures of yeast were exposed to air hence to oxygen, so aerobic respiration was mainly the way that yeast cells grew and reproduced. Aerobic Respiration: Aerobic respiration is a complex process which involves different steps of reactions and its purpose is to metabolize food molecules. As these reactions take place and food is broken down, energy is released which is then used to synthesize ATP from ADP (Adenosine diphosphate) and inorganic phosphate (Kent, 2000; p.101). These reactions are carried out by special enzymes. There are the three major metabolic stages in aerobic respiration: glycolysis (which is also part of anaerobic respiration), Krebs cycle, electron transport chain and oxidative phosphorylation. Krebs cycle: The central phase of the aerobic respiration and occurs in the mitochondrial matrix. It involves the production of acetylcoenzyme A (acetyl-CoA) (Kent, 2000; p.104). Electron Transport Chain: It involves the highest production of ATP during respiration, meaning the 90% of ATP is produced in this stage. This metabolic stage occurs in the inner mitochondrial membrane (Greenwood. et al. 2007; p.127). Glycolysis: Cell respiration has to do with the production of ATP by the oxidation of sugars, fats or other substrates. In this research as substrate was used glucose. When glucose is the substrate, the first metabolic pathway of cell respiration is glycolysis, which is carried out by enzymes in the cytoplasm of the cell. A small amount of ATP is produced in this pathway by the oxidation of glucose. Glycolysis consists part of aerobic and anaerobic respiration because no oxygen is used (Allot, 2007; p.73). Enzymes: Thousands of chemical reactions are carried out within a cell. These reactions most of the times occur in a very slow rate. For that reason living organisms make biological catalysts which are called enzymes and speed up these reactions. Enzymes are globular proteins which act as catalysts of chemical reactions (Allot, 2007; p.18). An enzyme can increase to more than a billion of times the rate of a chemical reaction. Also cells can control which reaction occurs in their cytoplasm by making some enzymes and not others. Enzymes achieve to increase the rate of a reaction by decreasing the activation energy (the minimum amount of energy required for a reaction to occur) (Green. Et al. 2008; p.167)of the substrate or the substrates, when binding to the activation site (is the part of the enzymes surface into which the substrate is bound and undergoes reaction) (Greenwood. et al. 2007; p.114) Enzymes are sensitive molecules with very specific structure which enables them to carry out specific reactions. This structure including the active site can be damaged by various conditions and substrates. This damage is called denaturation and is usually permanent for an enzyme and if denaturation is occurred the enzyme can no longer carry out its function. As a result when enzymes are required to catalyze a reaction, is necessary that they have appropriate conditions. It should be remembered that different enzymes have different ideal conditions. The factors that affect the enzyme activity are: the temperature, the pH, the substrate concentration. In a specific point for each of the previous factors, enzymes work in the most effective way, known as optimum conditions. The effect of temperature, pH and substrate concentration upon the enzyme activity which affects the growth of S. cerevisiae yeast cells are studied in this research. Effect of Temperature: As the temperature is increased in an enzyme-catalysed reaction, the rate of reaction is increased up to maximum in a specific temperature. This is called optimum temperature. The optimum temperature of Saccharomyces cerevisiae is 30o- 32oC. In temperatures below of the optimum, when increasing the temperature there is an increase in the kinetic energy of the reactants and there are more frequent collisions between the active site and the substrates, so the activity of the enzymes is increased. The rate still rises as the temperature increases; till it reaches the highest rate where is the optimum temperature hence the highest enzyme activity. Above this temperature the rate starts to drop rapidly. This is due to the high energy that causes vibration inside the enzyme with result the bonds which maintain the structure of enzyme to break. This causes denaturation and the active site can no longer fit the substrate. Overall, at very low temperatures the enzyme activity hence the rate is low due to the low kinetic energy of the substrate but there is no denaturation, at the optimum temperature the rate is the highest and levels off because the increase in kinetic energy of substrate is cancelled out by the denaturation of the enzyme and at high temperatures enzymes are denaturated and the rate falls dramatically because denaturation exceeds the high kinetic energy of the substrates. These are summarized in the following graph. Effect of pH (hydrogen ion concentration): Most of the enzymes operate effectively in a small range of pH values. Between these pH values there is an optimum pH value in which the enzyme activity is the highest. The optimum pH of Saccharomyces cerevisiae is 5.5. Acids and alkalis cause denaturation of the structure of the enzyme by breaking mainly hydrogen and ionic bonds with result the substrate cant fit the active site. Furthermore the charges of the amino acids within the active site are affected by pH changes, so the enzyme is not able to form an enzyme-substrate complex. Above and below the optimum pH the enzymatic activity hence the rate is reduced considerably. Effect of Substrate concentration: In an enzyme-catalysed reaction the rate increases in direct proportion to the substrate concentration. The optimum glucose concentration of Saccharomyces cerevisiae is 2%. At low substrate concentrations, the rate of enzymatic activity increases sharply as the substrate increases. This occurs due to the more frequent collisions between the substrate molecules and the unoccupied active sites. On the other hand, at high substrate concentrations the biggest part of the active sites have been occupied with result when increasing the substrate concentration there is little effect on the rate of enzymatic activity. Chapter 2: Methodology Objectives of the study: To determine how the different temperatures affect the growth of population of S. cerevisiae. To determine how the different pH values affect the population growth of S. cerevisiae. To determine how the different glucose concentrations affect the population growth of S. cerevisiae. Hypothesis: Hypothesis 1: The population of S. cerevisiae will grow the most at the optimum temperature, meaning between 28oC to 32oC, and also the population growth at temperatures below the optimum will be higher than the population growth at temperatures above the optimum. Hypothesis 2: In the optimum pH, meaning at low acidic conditions of pH 5.5 to pH 6, there will be the highest S. Cerevisiae yeast cell population growth. At pH levels above and below the optimum pH there will be less growth but this growth level will be relatively of the same degree for the values of pH above and below. Hypothesis 3: In the optimum glucose concentration, meaning about 2% glucose, will occur the highest yeast growth. In the glucose concentration below of the optimum there will be much lower growth, whereas in the absence of glucose there will be almost none yeast growth.

Materials/ Apparatus: Test tubes Burette Micropipettes Pipettes Pipette-fillers Graduated cylinder of 10mL, 250mL and 1000mL Volumetric Flasks of 250mL and 1000mL Funnels Spatula Weight boats Beakers Plastic wash bottles Plastic bottles Cover slip Haemocytometer Microscope Digital multi-log Balance Waterbath Magnetic stirrer Thermometer Ethanol 70% 0.1M Citric acid 0.2M Sodium hydrogen phosphate Distilled water Yeast: Saccharomyces cerevisiae Source of yeast: YIOTIS S.A, INDUSTRY OF NUTRITIONAL PRODUCTS, ATHENS, GREECE. Procedure: Day 1: The first step before the start of the aerobic fermentation of yeast was to prepare the buffers. For the preparation of buffers of different pH, citric acid (3-carboxy-3-hydroxypentanedioic acid) and sodium hydrogen phosphate (Na2HPO4) were used. Four plastic bottles, labeled each with one pH value (3, 4, 6, 8 respectively), were required. 100mL of each of the buffers were prepared. The stock solutions of citric acid and Na2HPO4 firstly prepared. For the preparation of stock solution of citric acid of concentration 0.1M and volume 1L, 19.2g of citric acid and 1L distilled water required. For the preparation of stock solution of Na2HPO4 of concentration 0.2M and volume 1L, 28.4g Na2HPO4 and 1L distilled water required. A balance and a weigh boat required for the measuring of masses. The solutions were added and stored in two volumetric flasks of 1L respectively, which measured the volume of distilled water. Citric acid and Na2HPO4 were added into the flasks with the aid of funnels. The volumes were measured and put into four different plastic bottles by using two burettes of 50mL. The validity of each pH value checked by using a digital multi-log. The next step was to prepare the glucose solution. For the preparation of glucose one volumetric flask of 500mL used to measure the volume of distilled water and to store the glucose solution. 10g of glucose were weighed by using a balance, a weigh boat and a spatula. Half of a 100mL beaker filled with distilled water was used to dissolve the 10g of glucose. A magnetic stirrer used for better dissolution. After glucose was complete dissolved, was added to the 500mL flask using a funnel. The rest of the flask was filled up to 500mL with distilled water. Then, the yeast solution prepared for the purpose of the experiments of that day. Every day a new yeast solution was prepared. For the yeast solution 0.10g of dry yeast were weighted from sachet with a spatula and placed on the weight boat. The yeast was added to a 1000mL volumetric flask filled with 500mL distilled water with the aid of a funnel in order to avoid staking of dry yeast in the cylindrical walls of the flask. Afterwards the solution was swirled by smooth shaking. After everything was ready the experiments for the studying of the effect of differing temperatures on S. cerevisiae growth initiated. Three water baths were prepared and each one adjusted in three different temperatures 30oC, 50oC and 60oC. Each temperature was tested by using a thermometer and a digital multi-log sensor. Two refrigerators were used for the low temperatures and adjusted at 5oC and 15oC. After all temperatures have been reached, the preparation of cultures started. Five test tubes labelled with one temperature each. The cultures were prepared with half an hour difference in order to test the stability of the temperature and to take a sample from each test tube and count the initial population. A pipette of 25mL used to introduce the glucose to the test tube. A 10mL graduated cylinder used to measure the volume of the buffer and then was introduced into the test tube also. Then with another 25mL pipette, 1mL yeast was taken and placed also into the test tube. The yeas t solution was shaken before taking the sample as yeast cells tend to sink to the bottom of the flask due to their weight. Afterwards by using a micropipette, a sample was taken from the culture inside the test tube and placed on haemocytometer and then to the microscope to count the initial population (the cells found in the borders of the chambers were counted). The haemocytometer is a specialised microscopical apparatus used to count cells and other organelles. A haemocytometer consists of two counting chambers. Each chamber consists of an arrangement of squares of different sizes which are used to count easily the cells. These squares of different size form different grid layouts. In the centre of each chamber it is found a grid of squares of 0.2mm 0.2mm 0.1mm dimensions. There is another grid of squares of dimensions 0.25mm 0.25mm 0.1mm, in each of the four corners around the central grid. The grids of squares of 0.25mm 0.25mm 0.1mm dimensions were used for the counting of the yeast cells. A cover slip is placed above the chambers, so the samples are spread equally due to capillary action on the counting area. The test tube was then placed for 24hours in the temperature corresponding to what was labeled. This procedure was the same for the rest four test tubes. In the end of the day the glucose solution 2% was placed in the refrigerator, the 1000mL flask with the yeast solution, the haemocytometer, the cover glass and all the other apparatus was cleaned with ethanol 70% and washed with distilled water and left to dry. The use of 70% ethanol for the cleaning of haemocytometer doesnt have any negative effect on the yeast cells that were place on it to be counted. This happened in the end of every day. Day 2: The next day each test tube was removed with half an hour difference in the order that they were left for fermentation. Then a sample was taken with the use of a micropipette and placed on haemocytometer and again to microscope to count the yeast cells. After finishing with temperature testing the next thing was to study the effect of pH levels on S. cerevisiae population growth. A yeast solution was prepared the same way as Day 1. The glucose solution was removed from the refrigerator. Clean test tubes taken and labeled with different pH values 3, 4, 6, 8. A water bath adjusted at 30oC. Again, every culture was prepared the same way as Day 1 and placed in a test tube with half an hour difference. All test tubes with different pH levels were placed in the same water bath for 24hours. Before each test tube was placed in water bath, a sample was taken to count the initial population of each. Day 3: The cultures were removed in the order that were left to ferment and samples were taken to count the yeast population from each one. Between each measurement the haemocytometer was cleaned as was mentioned in Day 1. Finally, the effect of glucose concentration on yeast population growth was left. New yeast solution was prepared. The water was adjusted at 30oC. In clean test tubes the new cultures were prepared to test the glucose concentrations. The test tubes were labelled each with one concentration value. Samples were taken from each to count the initial population. The cultures were placed in water bath to ferment. Day 4: The cultures were removed from water bath and samples taken to count the yeast population. Weaknesses and Improvements: Weakness Improvement In the populations of yeasts cells that were counted in the microscope, there were both alive and dead cells  or denaturated cells. A dye such as methylene blue could be used to determine in each counting the live and the dead or inactive cells. The cells which would remain colorless would indicate enzyme activity and the dead or denaturated cells would be turned into blue. Methylene blue should be used only after the fermentation has finished because it inhibits the yeast cells by consuming the hydrogen ions that are produced during respiration. The test tubes, where the yeast cultures were left for fermentation, were slightly closed on the top with cotton in order to prevent the entrance of other microorganisms. This cotton plug prevented the easy flow of fresh air (containing oxygen) inside the test tube. This limited the availability of oxygen supply that the yeasts required in order to grow aerobically. The test tubes can be placed to ferment aerobically in a closed container such as BioFlo 3000. This kind of bio processing systems provide a wide range of options that enables the researcher to adjust a standard air flow which includes different options of certain proportions oxygen ggand air which can respond to oxygen-demanding yeasts or any other microorganism. There was absence of some basic element sources in every yeast culture that are necessary for better fermentation conditions such nitrogen and phosphorus sources. Lack of such sources lead to relatively low cell growth comparing to the growth that could be achieved without the absence of such elements. Bacto-peptone can be used as an organic nitrogen source. Yeast extract makes available many bio nutrients required for the fermentation of yeast cells. It also provides essential water soluble vitamins, amino acids, peptides and carbohydrates. Chapter 3: Data Collection and Processing Calculation of cell concentration In order to calculate the cell concentration for each factor, the comperative mean values, which are displayed above, were used. These mean values were applied to the following formula which enables to convert counted cells into cell concentration: In the above formula, C is the viable cells/mL, N is the counted cells, D is the dilution factor and 103 is the haemocytometer correction factor. An example with the application of the formula of cell concentration for the factor of temperature at 5oC and after 24 hours of fermentation is shown below: In the case of 24 hours of fermentation at temperature at 5oC, the viable counted cells, N=34.25, the dilution factor, D=1. In all experiments, when testing the different factors, the dilution factor is always one (D=1).

The respective table values were used for each of the factors. The software that was used for the sketching of the graphs is, Graph 4.3 (Ivan Johansen, 2007). effect of Temperature on S. cerevisiae population growth The effect of pH on S. cerevisiae population growth The effect of substrate Glucose concentration on S. cerevisiae population growth 4.2 Interpretation Testing Hypothesis 1: Comparing the different temperatures that the S. cerevisiae population left to grow, it can be seen based on both the cell concentration and the graph, that below 30oC the of the population grows rapidly as the temperature increases; the yeast population almost doubles when temperature increases from 5oC to 15oC and almost triples when temperature increases from 15oC to 30oC . Above 30oC the growth of the population is highly decreased; yeast population becomes almost 3.5 times less when temperature increases from 30oC to 50oC and when temperature increases from 50oC to 60oC the population decreases very slightly. As a result, the highest S. cerevisiae population growth is observed at 30oC. Consequently this should be the optimum temperature. Moreover, as temperature below the optimum point increases the population increases more from its initial value than it does at temperatures above the optimum point. Overall the hypothesis confirmed. Testing Hypothesis 2: Evaluating the yeast population growth at the different pH levels, it can be seen that the increase of population above and below the value of pH 6 is almost the same. The fact that at pH 6 it is observed the highest population growth implies that this is the optimum pH level. The lowest growth is observed at pH 3 and pH 8. In these specific pH levels the growth is slightly higher at pH 8 (population increases approximately 1.7 times) than it is at pH 3 (population increases approximately 1.3 times). The growth is higher in pH 8 as it is closer to the optimum pH. At pH 4 the increase in population is almost the same as it is at pH 8. Both pH 4 and pH 8 differ by 2 pH levels from the optimum level but the yeast population at pH 4 increases approximately 1.982 times where at pH 8 the population increases 1.7 times. This shows that S. cerevisiae operates better at acidic conditions. Overall the hypothesis is confirmed. Testing Hypothesis 3: Analysing the growth of S. cerevisiae at different glucose concentrations and for 24 hours of fermentation, the results obtained show that in the absence of glucose from the culture the yeast population didnt increase at all. The only increase that was observed from its initial population was 1.091.1 times, meaning that this 0.1 increase may have occurred due to the capacity of energy within the yeast cells. At 1% glucose concentration it was observed sufficient growth. The yeast population almost doubled from its initial value (increased approximately by 1.8 times). In higher glucose concentration the yeast cells population respond greater and as a result a higher population growth was observed. The initial population increased 3.9 times, meaning that almost quadrupled. In even higher glucose concentrations the population increased highly again but not enough so to be able to say that at 24 hours of fermentation S. cerevisiae requires more energy to reach the maximum replication cap acity. The population increased 3.954.00 times, almost the same of that of 2% concentration. Moreover, based on the graph plotted for glucose concentrations, it can be seen that after 2% glucose concentration the yeast population reaches plateau without any further increase. So the limiting growth glucose concentration is at 2%. Overall the hypothesis is confirmed.
