Institutional racism in america Essay Example | Topics and Well Written Essays - 500 words

Institutional racism in america - Essay Example The US property appraisal system, formulated in 1930, allows whites to achieve property value ratings and government loans whereas the blacks struggled to enjoy such facilities. Majority share of the governmental subsidies went to the whites rather than the blacks even though blacks were comparatively poorer than the whites. Underrepresentation of blacks in critical positions has also been charged as institutional racism. Mass media such as TV and movies always like to employ whites at the top position. All these inequalities happened in America because of institutional racism. This paper briefly analyses the characteristics of institutional racism in America. â€Å"According to Census data, whites with high school diplomas, college degrees or Master's Degrees all earn approximately 20% more than their black counterparts. Moreover, whites with professional degrees earn 31% more than blacks and 52% more than Latinos†(Institutional racism, 2009). Even though, both whites and bla cks have similar educational qualification and expertise, the earning levels of whites and blacks in public institutions were unequal because of the institutional racism. Whites are getting special considerations in both public and private institutions. The employers give preference to the white professionals while they conduct a recruitment process.

Influence of Religion at Literature and Art review

Influence of Religion at and Art - Literature review Example This paper will begin with the statement that the twentieth century was the most discrepant period in the history of mankind. On the one hand that was the epoch of scientific, technical and intellectual progress and great hitches in all spheres of human activity. On the other, the 20th century was the age of deep spiritual crisis. Every person in the world revised old established ideas about good and evil. Thomas Mann called it the age of endless wars and revolutions (Jasper, 1992, p. 54). It assumed collisions not only between countries and classes but also in human minds and souls. The radical experience of the World War I and World War II was described by American writers who came to fight young, full of hopes and returned from the war with destroyed dreams and believes without finding the new ones. Such writers created their own literature - the literature of "Lost Generation". In their works Ernest Hemingway, William Folkner and others depicted disregarded surroundings, estrange ment and deep pessimism caused by cruel reality. Ernest Hemingway wrote " when men fight for the freedom of their country against a foreign invasion, and when these men are your friends, some few friends and some of long standing, you know how they were attached and how they fought, you learn, watching them live and fight and die, you learn that there are worse things than war. Cowardice is worse, treachery is worse, and simple selfishness is worse" (Brian, 1988, p. 73). People, who got the scar of the war did not believe in God any more. The crisis of the twentieth century was one of the social phenomena that had to be acknowledged before it was dealt with. The way out of the crisis was hard and long because the main reason of it was the changing of the attitude towards the Christian dogmas. Outstanding German philosopher Fridrich Nitse wrote: "Concept of God still was the strongest objection against existing We disclaim God. We deny the responsibility in God and due to this we'll save the world for the first time" (Pelican, 1991, p. 83). Another philosopher Thomas Mann said that Christianity was one of the bases on which our civilization lied. In such turbulent times every person who was spiritually free and not only swimming with the stream of the age had an urgent necessity to reappraise his values, to realize them again and stand up for them. The 20th century strictly criticised Christian morality. Nevertheless that criticism touched only the superficial ideas but the deep Christian dogmas that were found once stayed virginal (Jasper, 1992, p. 69). For the last two thousand years you could hardly find a literary work where the theme of religion, faith or God was omitted. These themes were omnipresent. Their variations - Christian images, symbols, allusions, associations, philosophical reflections on God were found in works of different writers, different genres and styles. American literature of the 20th century was not an exception. Till the time Kurt Vo nnegut's usage of Christian motives were not thoroughly examined. The critics had an opinion that Christianity and Vonnegut were almost incompatible. They supposed the writer's attitude towards Christianity was not serious but even negative. Only the last researches of his works showed the role and meaning of Christianity in author's world outlook. Religion played an important role in Vonnegut's artistic world and the Bible was the main element of the author's thinking. Vonnegut emphasised the positive beginning of Christianity, its appeal to universal love. Nevertheless Vonnegut thought that the Christian religion couldn't prevent shocking crimes of the 20th century. J. Lundguist wrote a book dedicated to Kurt Vonnegut and his works. In it he analysed Vonnegut's manner of writing and pointed out "the cosmic irony" as the main feature of writer's method. He also touched the theme of Christian religion especially while analysing the Vonnegut's novel "Slaughter-House Five" (1969). Lun dguist compared the main hero of the novel with Jesus Christ.

Organisation And Behaviour Report Management Essay

Organisation And Behaviour Report Management Essay This report will discuss the impact that different leadership styles may have on motivation in organisations in periods of change, it compare the application of different motivation a theories within the workplace and the usefulness of a motivation theory for managers. However, this report also explains the nature of groups and group behaviour within organisations; the factors that may promote or inhibit the development of effective teamwork in organisations and evaluate the impact of technology on team functioning within an organisation. The organisations that this report will focus are Tesco and Asda. Discuss the impact that different leadership styles may have on motivation in organisations in periods of change Leadership is an association through which one person influences the behaviours of other persons in an organisation. Motivation is the process by which the behaviour of an individual is influenced by others, through their power to offer or withhold satisfaction of the individuals needs and goals. (BPP Learning Media, 2010) Leadership styles and their impacts on motivation: Leadership is about influencing, motivating and inspiring people. The essential job of management is the well-organised and effective use of human resources for the attainment of organisational targets. Effective using of human resource cannot be achievable without motivate the employees of the organisation. Therefore, to motivate the employees, leadership styles play a significant role because they make the company culture that influences the organisation and its performance. There are different types of leadership styles and each type has its own impact on motivation in work organisations and those are autocratic, democratic and laissez-faire leadership. Autocratic leadership: The autocratic leadership style is one which leaders have absolute power over their workers or team. They tell people what to do instead of asking for employees opinions or suggestions. For example, Tesco use autocratic leadership because the company needs too or the tasks won not be approved out inside the business. Tescos autocratic leaders give employees their role and responsibilities. This can give their business clear route but it may also guide managers to overlook input from their teams. It is important when Tescos business faces a critical situation or when an immediate problem occurs that requires an urgent reaction. Autocratic leadership style allows Tescos managers to make most functioning decisions. For example, if an accident happens in the store, manager might take control to ensure a quick and co-ordinated reply, and they have the right to make the last decision. However, Tescos managers are attempting to convince their teams to accept their opinion. Also their manage rs get the opinions of the lower staff before taking a decision. So if they did not use autocratic then Tescos wouldnt be run sufficiently. Democratic leadership: Although democratic leaders make the last decisions, they call other members of the team to add to the decision-making process. For example, Tesco accepts democratic leadership to boost job contentment by involving team members, and helps to develop peoples skills. Under this leadership style, Tescos staffs feel esteemed, that is why staffs are encouraged to work hard by more than a monetary remuneration. Tesco chooses leadership roles to staffs in the organisation so that everyone is clear about their responsibilities, to implement the strategic decisions through efficient communication and doing a follow up on the employees to ensure that they providing quality services. This increases team motivation and encourages creativity. Laissez-faire leadership: Is a style where the manager observes that members of the group are working well on their own (Mullins, 2005). Tescos managers adopted laissez-faire leadership, where they give all authority and power to the employees and they must determine goals, make decisions, and resolve problems on their own. Working under laissez-faire leadership style, employees can improve their communication skills, teamwork skills as well as enhance loyalty and responsibility. See Tescos all leadership styles in (Appendix 1) Compare the application of different motivational theories within the workplace Motivation theories can be classified extensively into two different viewpoints. See content and process theories of motivation in (Appendix 2). Content theories emphasis on what motivates individual and process theories emphasis on the real process of motivation. Motivation is complex. Its influenced by withdrawals and reinforced by multiple factors. According to classic motivational theorists such as Maslow and Herzberg, human beings have a set of needs or desired outcomes and will act in such a way to fulfil them while other motivational theorists such as Victor and Locke argued that the informed expectations and particular targets will become motivator factors that lead humans to act and work in order to reach desirable goals. Maslow puts forward a theory that there are five levels of human needs which employees need to have fulfilled at work, see (Appendix 3). There are two things to remember about Maslows model. First, employee must satisfy lower level needs before they seek to satisfy higher level needs. Second, once they have satisfied a need, it no longer motivates them; the next higher need takes its place. In other hand, Herzberg theory suggests that there are two basic needs of individuals such as hygiene factors (environmental factors) and motivation factors, see (Appendix 4). Herzberg outlines the main issues concerning motivation: those factor that motivation employee in the workplace (motivation factors) and those factors that prevented job dissatisfaction (hygiene factors). Herzberg encouraged leaders to study the job itself rather than conditions of work. Porter and Lawler argues that human act according to their conscious expectations that a particular behavior will lead to specific desirable goals, see (Appendix 5). Three component of expectancy t theory are: E P (Expectancy): The employee believes that his/her efforts will result in acceptable performance. P R (Instrumentality): the employee believes that acceptable performance will lead to the desired outcome or reward. R (Valence): the employee values the reward. P 494 Comparing to other theories, Locke theory suggests that motivation and performance will be high if individuals are put specific objectives which are difficult, but accepted and where comment is given on performance. See (Appendix 6). Practical implication for the manager of goal theory include: the need for systematic identification of specific performance goals. The need for goals to be challenging but realistic; the importance of complete and accurate feedback on results and the need for goals to be determined either by a superior or by the individuals themselves. However, according to McGregor theory, manager of organisation posses two different assumptions about the human nature and s/he explained these two assumptions in two different theories: Theory X and Theory Y. According to theory X, the human being has always being inherited for the disliking of the work. They always try to avoid the work either they can do or not. According to him, managers always think that their employees are lazy. Manager has to forced, direct and controlled his people to do work. For example: Tesco use two motivation hierarchies (Maslow and Herzberg), see both hierarch in (Appendix 7 and 8). Tesco use Maslow theory because it suggested them if they achieve one level then it motivates them to achieve the next. Also Tesco aims to motivate its staffs both by paying interest to hygiene factors and by enabling satisfiers. For example, it motivates and empowers its staffs by suitable and opportune communication, by giving responsibility and involving employees in decision making. They forums this in which staff can be part of the discussions on pay rises. This shows credit of the work that staffs do and rewards them. Tesco staff can even control what food goes onto its restaurant menus. Employees consequently become motivated to make choices that will increase their use of the restaurants. In other hand ASDA believe in McGregor theory y. They completely have a positive approach towards their employee handling. They create awareness between their employees to gather information about different fields. The employees working as ASDA either individually or working as a team learn to face challenges. The different method adopted by ASDA is that they make different teams and make them competitor between themselves by providing the same task and hence see their performance by the results gained for the improvement of the company. Theory X does also apply to ASDA, especially where staffs are concerned. The emphasis is on the use of money and control to encourage employees to perform in the correct manner. In addition to this, ASDA give time and a half pay to employees on Sunday as a motivation. Evaluate the usefulness of a motivation theory for managers. Motivation is to encourage people to work, independently or in teams in the ways such as to create best results. It is the desire to apply high levels of attempted towards organisational aims, conditioned by the attempts and capability to satisfy some individual need. Motivation is apply to the whole class of drives, desires, needs and wishes. Managers motivate their subordinates is to say that they do those things which they hope will satisfy these desires and compel the subordinates to perform in a desired method. The most important task of management is to motivate others. It comprises the abilities to communicate, to set an example, to challenge, encourage, getting feedback, to develop and train, to inform and to provide a just reward. See motivation process on (Appendix 9). Employees have to be treated with diligence. The manager has to stay friendly as well as maintain a level of distance with his/her staff. It is a tricky ground to tread. The staffs look up on the manager as their leader. They expect maturity, rationality and understanding from their superiors. Simple things like calling people by their first name, chatting or even a general inquiry about their well-being, brings in a feeling of belongingness. All the employees in the organisation vibrate to a different place. A treatment that motivates one may not motivate the other. Understanding the difference in character and temperament in between the individuals is important. Managers set reasonable goals. Planning too high task creates a feeling of non-achievement, right from the beginning itself. The goals set should be such which looks feasible to the staffs to be achieved. A slightly higher target than expected provides a challenge. Explain the nature of groups and group behavior within organisations The term group can be defined as two or more persons interacting and working together for a common purpose. When people work in groups rather than as individuals, the goals of the organisation can be easily achieved. However, working in a group is a complex task. Group dynamics refers to the interactions among the members of a group. A work group of an organisation is the most important base for the social identity of employees in that organisation. Therefore, performance at work and relationships outside the organisation are influenced by the nature of groups in the organisation. Nature of Groups: Different kinds of groups are created to get specific results in organisations. The members accept a common task, become mutually dependent in their performance, and interact with each other to promote its achievement. There are three views on the nature of interaction between members of a group. The first view is the normative view, which describes how to carry out activities and manage a group. According to the second view, group dynamics includes of a set of techniques which include, role play, team building, sensitivity training and self-managed teams. The third view explains group dynamics from the point of view of the internal nature of the groups. The structure of groups and performance are discussed in this view along with the effect of groups on individuals, other groups, and the complete organisation. Dynamics of Group Formation: Organisations form groups for a variety of reasons. Different classical theories of groups attempt to explain why managers form groups. The theory of proximity suggests employees closeness as the reason because individuals who working at places located close to one another tend to form groups. According to balance theory, group formation results from the resemblance of attitudes and values between members. Individuals with common interests sustain their relationship by an equal balance between their attitudes and common interests. Another theory of group formation is the exchange theory. It suggests reward-cost outcomes of interaction as the reason. By becoming members of a group, individuals complete their need for association. Formal Groups: A group formed by the organisation to achieve a specific task is termed as a formal group. The organisation structure a formal group and gives tasks and responsibilities to different members with the intent of reaching organisational aims. Command groups and task groups are examples of formal groups. A command group is relatively permanent in nature and finds representation in the organisation chart. Task groups, on the other hand, are formed for a specific task and are temporary in nature. Informal Groups: Informal groups are formed by the staffs themselves. The reasons for the formation of informal groups can be the need for closeness, ordinary interests, growth or support. There are two types of informal groups: friendship groups and interest groups. Members of friendship groups have a friendly relationship with each other, common interests and are similar in age and view, but interest groups are formed to manage an activity and are temporary. The Five-Stage Model: According to the five-stage model of group development, all groups pass through the forming, storming, norming, performing, and adjourning stages. Forming: This is the first stage of group formation where members aim to identify acceptable behaviour in a group. The members try to format their behaviour so as be a part of the group. Storming: In this stage, disagreements about leadership between members might give leads to other involvements. By the end of this stage, a comparatively clear structure of positions in the group emerges. Norming: This stage of group increases a sense of comradeship in members through the development of close relationships. Performing: In this stage, members of the group show committed performance to achieve aims defined in the norming stage. Adjourning: This is the last stage for provisional groups such as task groups or committees formed to do some tasks. After this stage, the groups stop to exist. While some of the members may feel happy about the achievements, others may be unhappy that they will lose friends after the group disperses. The effectiveness of groups is supposed to increase through the stages. Discuss factors that may promote or inhibit the development of effective teamwork in organisations An effective team is one that achieves high level of task performance, member satisfaction, and team viability. There are a number of factors that are required to develop effective teamwork, and those factors are: good leadership, effective communication, diversity and plan for disagreement resolution. Leadership is one of the most important parts of teamwork. This means that the team leader have the ability to create and sustain a working culture that is positive, which in turn will help to motivate. For example, Tesco have good leadership and this helps them to motivate and even inspire the team members to get involved in creating a positive working environment, along with high levels of obligation. Tescos team leader not only focuses on their own aim and direction of the team, but also makes sure that the other members of the team share this focus. Also they are capable to promote a high level of morale between the team members so that they feel supported and valued. Tesco train their employees to have good and effective communication because communication is a very important factor of interpersonal interaction. Therefore, one of the key facets of teamwork is open communication, wherein it enables members of the team to expressive their feelings, plans and shares their ideas, and understands each others viewpoints. Also in case of poor communication observed Tescos leaders work around the aspect and make way for effective communication between the team members. Diversity also promotes creativity, innovation, and raises Tescos awareness and respect for differences, which will support effective teamwork. However, team members have a way of saying their opinions without fear of causing offense to anyone. In fact, it is recommendable for the team leader to actually sit with the parties in disagreement and work out the differences between them. However, teamwork can only come about when the team leader sets a task, which can be following by the team members. Evaluate the impact of technology on team functioning within a given organisation New technology has been introduced into the workplaces. Many organisations see new technology as the means to increase profit and to stay competitive in a marketplace. For example, at Tesco, IT is at the heart of everything they do to make shopping better for customers. New technologies can free up Tescos staff capacity, increase job satisfaction through better communication and improve role responsibilities, by giving different grades of staff an opportunity to take part in new tasks. On the positive side, new technologies have an impact on how staff can be trained and updated. Examples include simulation technology, accessing information via handheld devices, interactive DVDs and online training. Tesco use online technologies because it is easier for staff to access information, share good practice and keep up to date with new research. The use of new technologies can improve and in some cases hinder team functioning. As technology changes teams must update and maintain their knowledge in order to function effectively. E-mail, Mobile phones, groupware and computers are technologies which have improved team functions within an organisation. Tesco use these technologies to improve team functions. Email allows staffs to communication with each other from different place which means that Tesco team members do not need to be in the same place at the same time in order to communicate effectively. They use mobile phones because it allow teams to communicate even when team members are out of the office or otherwise unavailable. However, Tesco use personal computers because it allows their team members to carry out different tasks and communicate more effectively. IT systems play a key role in helping Tescos deliver strong profits and they improved scanners, better self service tills, and checkout cameras were helping it reduce queues. Self-service checkouts now account for a fifth of all of Tesco transactions. Recommendation: This recommendation allowing British Airways and Coca Cola Conclusion: After studying and a analysing the results of this report show that there are

Marijuana Use: An Ethical Examination Essay -- legalization of marijuan

Works Cited Missing Instead of addressing the tiresome argument about whether or not marijuana should be legalized in the United States, I would like to examine a much more fundamental question: whether or not it is right to use the drug. This problem is strictly an ethical one. If we are to examine only the moral implications of the action then we must discard governmental laws from the equation, for this decision could be made anywhere, at any time, under any sort of governmental regime, under any set of laws, which after all are only that particular government’s best guess at morality and who’s to say their judgment is any better than yours? Knowing that this decision is a rather daunting one, I’ve enlisted the help of three friends, Aristotle, Immanuel Kant, and John Stuart Mill, to aid in the decision making process. It just so happens that they are experts in the field of ethics. Aristotle is an ancient Greek philosopher, really the first philosopher to use the word â€Å"ethics†. His major book on ethics is titled Nicomachean Ethics (Bostock 1). In order to understand Nicomachean Ethics and apply it, we must first understand how Aristotle viewed the world. Aristotle sees the world in terms of ends, purposes, and functions. In nature, the end of the acorn is to become an oak tree. In human affairs, the end of architecture is to produce buildings; of shipbuilding, to produce ships; of medicine, to promote health. Humans too have a function, an ultimate end; this Aristotle calls eudaimonia. The traditional translation is happiness, but this translation is misleading. To put it most aptly eudaimonia â€Å"connotes overall success and prosperity and achievement, though it also connotes something that we may call... ... the world would most likely be made up of people enjoying pleasure, something that can not really be considered bad. Many would argue that the world would be full of drug addicts, but this is not the world that we have set up. According to our perceived duty, all must use marijuana in moderation, and to use it to excess would be just as offensive to the duty as would be not using it at all. We have now heard from three very distinguished Moral philosophers, and all have said that moderate use of marijuana is not a bad thing, one even calling it our duty. The most common type of actual moral reasoning is a loose combination or confusion of methods (Sweet 4). So, if we combine all that we have heard, the only conclusion that can be drawn is that the use of marijuana, as a bodily pleasure, is morally justifiable, probably more so than not using the drug.

Energy from Waste

Energy FROM WASTE ( EfW ) Introduction Energy from waste is a construct that is going more relevant to society as the general consciousness of energy efficiency and waste direction additions in the public sphere. It merely means that waste generated from families, industries and commercialism is used to bring forth energy in the signifier of heat, transport fuels like Diesel and electricity. The EfW procedure can make energy from different types of waste utilizing a assortment of engineerings including:Residual waste which is waste which can non be economically or practically reused or recycled and is normally subjected to thermal intervention like incineration, gasification or pyrolysis.Biodegradable waste like nutrient waste and sludge which can be decomposed by the action of microorganism which is normally used in Anaerobic Digestion ( AD ) workss.The Waste Hierarchy The preferable order in which waste must be managed is called the waste hierarchy. The most good option to the environment is to forestall waste, nevertheless, this is barely possible in the current socio-economic context. The following best thing is to recycle, and so recycle. After which other recovery methods like EfW may be applied before eventually any waste is disposed in a landfill. The Waste Hierarchy is a legal demand of the European Union ( EU ) Waste Framework Directive. It means that waste can merely be presented to the EfW procedure if it can non be efficaciously managed through reuse and recycling. In consequence, merely waste edge for the landfill sites can be redirected to any of the EfW procedures. EfW or Landfill? Although both energy generated from waste recovery and landfills release C into the ambiance in the signifier of C dioxide, their possible impact on clime alteration through planetary heating vary greatly. This is because landfill sites besides release methane into the ambiance, of which it has been proven that methane is about 25 times more detrimental than C dioxide. The United Kingdom authorities has established a Climate Change Act to lawfully implement its committedness to cut down its nursery gases ( GHG ) emanations by 80 per centum by 2050, compared to degrees in the basal twelvemonth of 1990. This statute law is now besides one of the drive forces behind the consumption of EfW methodological analysiss, as they have been recognised as feasible agencies of cut downing GHG emanations. Due to less detrimental emanations from EfW procedures, they have been placed higher in the Waste Hierarchy than fain waste in landfill sites. Energy from Residual Waste Residual waste is a mixture of different things including plastics, and from things that are late turning and are biodegradable such as nutrient, paper, wood, etc. This is why residuary waste is sometimes referred to as partly renewable energy beginning or low C energy beginning as opposed to fossil fuels which have been belowground for 1000000s of old ages therefore are regarded as non-renewable energy beginning. The most common thermic method for let go ofing energy from residuary waste is incineration. Although Advanced Thermal Treatments ( ATT ) such as gasification and pyrolysis are in usage, their consumption is more limited due to be and ATTs tend to be used in smaller sites. The incineration method merely allows the hot gases produced to be used to boil H2O which so releases steam to turn a steam turbine that generates electricity and/or heat. However, ATTs can in add-on to bring forthing steam to turn turbines make a mixture of compounds such as gases or oils that can be cleaned and burned straight in gas engines or turbines or converted to man-made natural gas or conveyance fuels. Residual waste may be capable to pre-treatments to pull out more recyclables and better both the calorific value ( CV ) and biogenic content of the waste. The more common types of pre-treatments include mechanical sorting, mechanical biological intervention ( MBT ) and mechanical heat intervention ( MHT ) . Pre-treatments by and large take recyclates, wet and homogenize the waste into what may be termed refuse derived fuel ( RDF ) or solid recovered fuel ( SRF ) . Finally MBT can be used to take biogenic stuff that can be sent to AD works to retrieve energy. The EU Industrial Emissions Directive has set really low degrees of emanations that may be released from EfW workss, and besides encourages environmentally friendly runing conditions within EfW workss such as flue gas clean-up which ensures that gas pollutants and particulates are removed before emanations are released into the ambiance. These have ensured that EfW workss are a low beginning of environmental pollution. Energy from Anaerobic Digestion Anaerobic Digestion ( AD ) is a of course happening procedure where microorganism interrupt down organic affair, in the absence of O to bring forth biogas and digestate. The biogas is a mixture of C dioxide and methane while the digestate is a nitrogen-rich fertilizer. The biogas can be used to raise steam and burned straight in Combined Heat and Power ( CHP ) Plants or Vehicle Combustion Engines ( VCE ) to let go of energy. The digestate provides a renewable beginning of fertilizer which helps to replace lost foods from agricultural lands. It is besides a really good dirt conditioner. AD engineering has been in topographic point for up to one hundred old ages, nevertheless, it is merely late that it has started to utilize non-sewage sludge wastes such as purpose-grown harvests and nutrient waste as feedstock. There are a myriad of AD engineerings including dry or wet ; mesophilic or thermophilic and individual or multi-stage digester. In dry AD, the digestion procedure takes topographic point from waste in its solid signifier while in wet AD, the waste is foremost converted into a mush. Mesophilic AD involves the usage of bacteriums that thrive best at 35C to 40C of temperature while thermophilic method uses bacteriums that can be active at 55C to 60C. A single-stage digester have all biological reactions occur in a individual reactor or armored combat vehicle while a multi-stage digester use several armored combat vehicles to optimize the bacterial reaction. It is more advantageous to divide out biogenic waste and send to an AD works instead than holding it as portion of residuary waste. The ground being that digestate from residuary waste intervention can non be used as fertiliser replacing on agricultural land because it may hold contaminations from assorted waste and it would be wasteful to execute the series of trial required to run into the quality of digestate from an AD works. Crops grown specifically for AD are non considered as waste, therefore merely AD workss that use sewerage sludge and biogenic waste as feedstock are considered as EfW workss. THE PROXIMITY PRINCIPLE This rule supports the thought that waste must be processed every bit near as it is possible to where it was generated. This is to guarantee that one community is non taking on waste produced by another and advance the rules of autonomy in waste direction. However, it may be possible to utilize a more distant works where it is the best operable environmental option ( BPEO ) . Emission FROM EfW Energy from waste workss that use assorted thermic engineerings contribute a really little fraction of particulate and other emanations due to really rigorous bounds imposed by the EU under the Industrial Emissions Directive ( IED ) 2010. In order to run into these bounds such EfW workss must cut down emanations by using the most environmentally friendly burning techniques, take all harmful gases and particulates such as heavy metals before release into the ambiance.

The Case of Online Learning

Students go to schools to learn. Through their reading on their textbooks, the inputs from the teacher, and their interactions with other kids, learning is facilitated, even enabled in traditional schools. The public school system is also built upon the notion that there is direct interaction between and among the teacher and the students for the impartation and facilitation of learning. With the growth of the Internet, several applications have been developed to cater to the needs of people who want to study on their own pace from the comforts of their home or wherever they want to study.As such, there are now a lot of online learning programs designed to facilitate the learning in online environments. As a testimony to the growth of online learning, there are now more than 3. 5 million students who are participating in various online learning platforms (National Postsecondary Student Aid Study, 2000). Some of these platforms serve to reinforce the interactions of teachers and stude nts in addition to classroom interactions. There are also companies that offer complete online degrees, thus deviating from the usual method of classroom learning.Institutions of higher learning in the United States, Europe and elsewhere in the world, are now offering online classes. According to a study of several academic leaders, it appears that students are satisfied with the results of online learning as much as with the traditional learning contexts. As it stands now, most of the institutions offering online learning are those that are for-profit. This is perhaps due to the high costs associated with maintaining the systems and personnel needed for the online learning classes. Perhaps when the costs of the system decrease, more institutions may offer online classes.It cannot be denied though that online learning programs are on the rise. Post-graduate degrees, particularly, are utilizing online learning programs (Nagy, 2005, p. 80). This paper seeks to look into the online lea rning phenomenon, the different issues arising from it and the way in online learning differs from traditional schools. Given the differences in approach, it would be necessary to analyze online learning and look at the areas where it works best and at the areas where it is not very effective. In comparison with traditional schools, there are marked differences in online learning settings.In the first place, students and teachers are no longer â€Å"physically present† to conduct the learning sessions and discuss about issues and concerns regarding different topics at hand. The level of discussion has been transferred from physical presence to virtual presence. Moreover, students and teachers alike can no longer see each other. Hence, they can no longer rely on visual and body clues whether they understood each other or not. The interaction tends to be limited to online interactions, which are largely driven by text and written communication.The Basics of Online Learning Onli ne learning is a high technology variation of distance learning through correspondence, which have been used by schools and educational institutions prior to the Internet’s widespread use and popularity. With online learning, there is a number of technology being used to facilitate the learning process. There are multi-media applications and presentation available through a CD-ROM or through a secure website, emails, blogs, wiki, chat, as well as podcasts and discussion boards among others being used for this purpose.Most of the time, these tools and equipment are used together to help maximize the learning process for the student. The usual approach in online learning is the establishment of a Virtual Learning Environment, which has a particular kind of user interface so that the student can navigate through the system more easily. A number of universities are now offering online college degrees in addition to the degrees being offered through the traditional programs that t hey have. Online certificate programs are also widely available.In addition to traditional schools and online classes, a lot of universities are also using the Internet to provide advice to students, counsel them, and make books and resources available to students wherever they may be (Salmon, 2000, p. 27). There is a trend towards blended learning, in which traditional classroom instruction and online learning are blended together. Through this approach, students are able to maximize their time during the class sessions and they also make use of multimedia to address different topics in their online classes.Usually, online learning boosts the student’s learning capabilities or help them do something specific. The multimedia content may have information only or in some cases, the multimedia applications also require the student to perform some activities or tasks related to the lessons being studied (Salmon, 2000, p. 31). Pedagogical Approaches used in Online Learning Online learning is similar to traditional schools in that it still has to use the pedagogical approaches although there are differences in the way that these approaches are applied to online learning.In the first place, the instructional design for online learning is also developed by an educator based on the curriculum being followed by the online course. The social constructivist pedagogy is also applied to online learning. Through the different technological tools available, the students and the teachers can collaborate together in different online activities. Through the use of forums, and other interactive tools such as blogs, the students and the teacher alike are able to create content for themselves and for the benefit of the whole class (Lambropoulos & Zaphiris, 2007, p.106). There is also a conversational model described by Salmon (2000, p. 24), which works best in online discussion forums occurring online. Through the online conversations and collaborations, online students can also develop the cognitive aspect of learning since the senses and the brain coordinates well in doing the online learning. Their learning process though is slightly modified because of the different situation in online learning. Yet, the emotions of students are also engaged in the process of learning online (Areskog, 1995, p. 37).The difficulty, however, is that detecting these emotions are not automatic and the teacher and students may have to rely on word clues as to the emotional state of a student. After all, nobody can see a person be affected emotionally through the texts being written in chat boxes. Truly, the realm of the physical is no longer present in online learning environments. The behavior of students in online learning environments is also a little more difficult to measure and gauge as they are not able to make a presentation in front of the whole class or catch the stare of the teacher.If a student is bored during an online class, the teacher has no clue whatsoev er except perhaps the lack of paragraphs and sentences being communicated by the student. Perhaps, the teacher or facilitator may be able to detect a bored and sleepy student if he makes an irrelevant remark. The context of online learning is also very different from traditional schools. At least, in traditional schools, students may be able to enjoy the full environment of the academe—the library, the laboratories, as well as interactions with different teachers and students.This is lacking in the online learning environment. True, the student may have additional learning opportunities online but the experience of being in an academe is still different. Although this is the case, online learning should enable a student to still interact with other people and help them embark on a joint pursuit of learning and discovery of knowledge. Likewise, the pressure emanating from other students is also important in the learning process.
