Overview of Theories Essay Example | Topics and Well Written Essays - 750 words

Overview of Theories - Essay Example By understanding the numerous theories, it thus becomes possible to understand the behavior of children. The discussion below is an over view of three vita theories that explain the cognitive development of children. The three include Piaget’s Cognitive-Developmental Theory, Vygotsky’s Sociocultural Theory and Bronfenbrenner’s Ecological Systems Theory. Each of the three just as hinted above offers a varied view to the development of children. The discussion is therefore an over view of the three with the view of portraying the fundamental features of the theories and the ideas that each theory foster. By analyzing such, the discussion thus portrays the essence of the environment among other factors in the development of the children. The theory strives to explain the nature of knowledge. It explains the process of acquiring knowledge, its construction and subsequent use of knowledge in humans. The theory therefore portrays the fundamental factor that influence the definition of knowledge and the factors that influence the relevance of such. The theory asserts that children begin by understanding the world around them before experiencing the discrepancies that exist between their knowledge and the actual features of the environment as they interact with the people. The theory underscores the importance of language. It explains that language is a contingent on the process of cognitive development. The theory therefore explains the factors that influence the cognitive development of individual by explaining the development of children. The people that a child interacts with first influence the nature of their development. Such people as the family members influence the child’s understanding of the society. Furthermore, the theory provides language as a means of assessing the cognitive development of a child. Using language

How to contribute to a community of difference and being a global (See Essay

How to contribute to a community of difference and being a global (See Guideline) - Essay Example As a means of this reality, it is incumbent upon the individual who wishes to integrate key level of change to understand that such a level of change does not only impact upon their own local community, it has global impacts in ramifications. In such a way, this brief analysis will discuss some of the key ways in which an individual can interact with different people, cultures, politics, and/or ideas as a means of effecting positive and lasting difference within the global environment. Furthermore, if brief discussion of what it means to be a global citizen in some of the ethical constraints that that’s necessarily entails will also be discussed. One of the most important means of contributing to a lasting degree of change and difference within the world is perhaps with regards to the video featuring Sir Ken Robinson available from TED. Although the video in question was specifically interested in education and the means by which future generations are being prepared for the c hallenges that await them, the reality of the fact is that this subject matter is applicable to all individuals (Garr et al, 2012). Ultimately, as a means of making sense of an increasingly complex world in which fewer and fewer elements of knowledge can be obtained and leveraged by anyone individual, society and the education system as a whole have sought to limit and ultimately constrain the extent to which individuals are exposed to certain ideas and/or types of education. However, such an approach is damaging due to the fact that it restricts the potential that the creative young minds could bring to a world that they might otherwise engage with a more complete approach. In short, although the impacts upon students are most definitive, such a faulty approach also impacts upon adults due to the fact that encourages each and every member of society to limit and constrain their worldview into a shallow rather presumptuous model of limited understanding. Similarly, another means by which the global citizen and seek to integrate change of a systemic level is with regards to the level and extent to which he/she understands the far-reaching replications of choices and models by which they ascribe to follow. What is meant by this is the fact that an appreciation for culture and key differences with regards to individual backgrounds and ethnicities is necessary for any change model to work effectively (Hornstein, 2012). As a corollary, the reader can easily understand the situation in which a simplistic model of changes advocated however, it is completely and entirely unsuited to key realities that exist in different parts of the world, different religions, different political associations, or different ethnicities/racial backgrounds. As a means of being mindful of such a reality, it is necessary for the global citizen/individual agent of change to perennially be mindful of the means by which such realities can impact upon their decision and framework. Finally, it must be understood that due to the fact that so many issues face the current generation means by which change can and should

Coal chemical looping Research Paper Example | Topics and Well Written Essays - 3000 words

Coal chemical looping - Research Paper Example As it has been reported that the global demand for energy is likely to be fulfilled by the exploitation and utilization of fossil fuels in decades to come, the need for developing effective systems for the capture and storage of CO2 has become indispensible (Yue 2010). While, the significance of this observation is undeniable the present systems and frameworks which are utilized extensively in the industry are inadequate and do not support the advancement of certain aims and objectives that are associated with the development of suitable technologies. As noted by Yue (2010), present solutions for solving the issue are marked by the absence of cost-efficiency, capture efficiency and conversion efficiency which is an alarming scenario for both researchers and analysts alike. This observation proposes that the technology of chemical looping combustion (CLC) and its related processes have emerged as an innovation which presents numerous prospects and opportunities for the development of energy and power-related technologies by minimizing the risks, limitations and drawbacks that are associated with the solutions that are currently and presently available within the industry. Numerous studies and researches have established that the CLC technology boosts of impressive efficiency rates for the purpose of producing electricity and hydrogen in scenarios where the system of gasification is associated and integrated within the chemical looping technology (Yue 2010). Since the inception of the innovation, empirical studies have also been able to establish the types of suitable components that should be installed within an effective CLC system to maximize desired outcomes. This aspect involves the selection of solid fuels that can be used in chemical looping in addition with the oxygen carriers which have the potential to enhance the oxidation process. Even though, these observations have revealed the possibility of utilizing an extensive range of carbonaceous fuels and ca rriers, the scope of this paper focuses on the process of coal chemical looping such as the coal-direct looping process and the process of syngas chemical looping. Furthermore, the paper also explores the practical applications of chemical looping combustion in organizations such as General Electric and Alstom. In conclusion the research examines the advantages, challenges and limitations that are associated with the process of coal chemical looping in the light of recent researches and studies. The application of chemical looping combustion (CLC) processes is a revolutionary advancement and innovation in the industry, as stated by Yue (2010): Chemical-looping combustion (CLC) is a new alternative to conventional combustion that prevents the CO2 from being mixed in the combustion gases. This is accomplished by preventing the air-N2 to be present in the part of the reactor system where the oxidation of the fuel takes place. (p. 527) The introduction and subsequent incorporation of ch emical looping techniques and strategies was impelled by the absence of frameworks that could be applied for the separation and conversion of chemicals during the occurrence of various product-related procedures (Fan 2011). While, this observation is reflective of the traditional demands and needs which initially required the launch of chemical looping techniques, contemporary applications of chemical looping essentially aim to fulfill the need of establishing a modern, optimized and effective

Graduate level Economic question Assignment Example | Topics and Well Written Essays - 250 words

Graduate level Economic question - Assignment Example The outlook beyond 2012 is positive, where investments from the EU, Japan, China etc resume, and banking hubs like HK and Singapore resume expansion in developed economies. The deficit shall continue to increase for the foreseeable future. The government is printing like never before to keep the impact from its citizens. Due to this huge unsupported cash in the economy, the result shall be a hyper-inflationary trend that shall fuel an even tighter control on spending from consumers. The result will be a sudden loss of the US dollar’s purchasing power, causing other countries to exit long term treasury bonds to safer pastures (Williams 13). As soon as that happens, the bottom will fall out of the markets, as the others’ fear of American collapse will not fuel the support to the dollar, as the US shall have internally made it’s currency worthless. Federal reserve Policies will focus on a sustained purchase of gold to back the huge amount of dollars not backed by any assets, thereby causing gold to soar, and therefore become unaffordable to America itself. The feds will have to raise interest rates to protect the dollar, causing a fur ther slowdown in demand (Williams

The Student Motor Company Case Study Example | Topics and Well Written Essays - 1500 words

The Student Motor Company - Case Study Example In order to mitigate the competitive challenges The Student Motor Company invented a subcompact car i.e. Zinger. The normal preproduction testing along with the development of automobiles usually takes around forty-three months. However, the management team of the concerned company had consented for the production of the new car i.e. Zinger within two years. While test driving, the management had analyzed two vital faults within the car being manufactured. In this regard, it has been determined that the company used gasoline tank and the tank had been fixed in a way that a crash would create a puncture in the tank. Moreover, the design also entailed the risk of gasoline entering the driver’s chamber and any further ignite can lead to massive flames (Fall 1-4). Another fault as determined within the production of Zinger is the emission standard. It has been noted that it is the responsibility of the company to meet the emission standards before sale because after the sale it is the responsibility of the owner to abide by the emission standards. Zinger was launched in the market without considering the manufacturing defects. It has been further noted that the director of the company claimed that if the manufacturing department has involved standards to minimize the explosion risk then it would have raised the price of the product. Considering these aspects, it can be viewed that the company did not meet the ethical standard. ... Due to the company’s unethical decisions, the customers faced life risk situation (Fall 1-4). Q2. The ethical standards that might have been considered in resolving this dilemma is to stop the launch of the vehicle. In this regard, it can be ascertained that the company’s management or its stakeholders might have undertaken measures to mitigate the manufacturing defects. The research and development department might have put more effort in the establishment of a product that would be beneficial for the society. In this aspect, it can be ensured that this particular ethical standard has not been met by the company. This has resulted in the vital loss of the customers who purchased the car. This is the major consequence pertaining to the ethical standard that can affect the society at large (Fall 1-4). The following ethical initiative that can be mitigated by implementing certain alternative measures is meeting the Environmental Protection Agency (EPA) emission standard. In further discussion, it can be revealed that the company might have followed the emission standards incorporated within EPA. According to the EPA emission standard it is the responsibility of the company to meet the standard before the sale of the products. The Student Motor Company had not ensured emission standards before the sale of Zinger. This will lay greater consequences on the customers. This is because the emission standard of EPA reveals that after the sale of the car, it is the responsibility of the customers to mitigate the emission standard. It is difficult for the customers to gain immediate information on emission standards. In keeping with the economic alternatives, the company might have assured a better

Why are so many high school students dropping out before graduation Essay - 1

Why are so many high school students dropping out before graduation - Essay Example The organization aims at encouraging teenagers to explore their potential, through weekly national campaigns, to bring about social change (â€Å"11 Facts About Dropping Out†). In this competitive age spurred by globalization, there is a need to remain relevant. This implies that countries need to ensure they produce competent and productive workers for economic development thus moderated costs of health care and other social services (Monrad). According to Rumberger and Lim, causes of high school dropouts are categorized into individual and institutional perspectives; therefore, the student’s mindset and conduct are among what individual perspective highlights. These factors relate to the individual, and others include school performance, disengagement, and recurrent residential and school mobility. Dropping out of school is viewed as a process instigated by detachment from school. This implies that the student slowly gets swayed away from the idea of school because of reasons such as undertaking adult duties that consist of taking care of siblings, having to get a job that involves long hours and becoming a parent early. The background of the student is the core foundation of the risk factors identified in the institutional perspectives; moreover, background refers to the environment surrounding a student, and it comprises socioeconomic status, dependable figures in his/her life that is single or step parent and the situation at school. The nature of family a student is raised in is quite crucial and entails the structure i.e. who the breadwinner is practices i.e. values and norms, and resources (Rumberger and Lim). The situation at school entails the behavior and attitudes of teachers i.e. do they interact well with the students, nature of administration i.e. rules and regulations, school structure and resources available to students. Rules and regulations that bring about dropouts include Grade Point Average (GPA) minimums, zero-tolerance

The Decolonisation of Africa 1959-1964 Essay Example for Free

The Decolonisation of Africa 1959-1964 Essay To what extent was Britain able to retain control over decolonisation in Africa between 1959 and 1964? By 1959 decolonisation in British Africa was well under way, for example, the Gold Coast in West Africa had become independent in 1957, Nigeria and Sierra Leone were well on their way to independence, and agitation and advances towards independence were already taking place in Kenya and Tanganyika in Eastern Africa. By 1964 this had spread throughout Britain’s African territories and many more had either become independent or started their journey and development towards independence, as the â€Å"political face of the continent was transformed†[1]. This essay will examine what it was that led to this huge change in policy towards Africa, from a time at the beginning of the 1950s when no one expected any of Britain’s colonies to become independent within a generation, let alone within a decade, to a time in the mid-1960s when Britain’s colonial possessions in Africa were severely dwindling and there was a clear line of policy towards decolonisation there. Even in 1959, as Hemming recognises, â€Å"a conference of East African governors agreed that the likely timetable of independence would be: Tanganyika in 1970, Kenya in 1975 and Uganda somewhere between the two†[2]. In fact Tanganyika gained independence in 1961, Kenya in 1963 and Uganda in 1962. As Hemming identifies, â€Å"a fifteen year timetable had been reduced by 80 percent†[3]. This essay will look at such questions as: How can we judge if Britain was in control? ; Was Britain in control of the pace, or the actual process of events of how independence came about? ; Was Britain in control of who to transfer power to? This essay will attempt to answer these questions by examining all of the various problems, and pressures with which Britain was faced regarding its African colonies, which can been seen to have taken the control of decolonisation in Africa between 1959 and 1964 out of Britain’s hands. It will look at whether Britain really wanted to maintain control of its colonial territories, or whether, once Britain had decided not to keep its colonies, it actually did not want to remain in control of decolonisation in Africa. In some cases did it actually make it easier for Britain to allow control of African decolonisation **** out of its hands. This essay will examine whether it is certain that once the ‘wind of change’ of African nationalism began spreading through Africa, that Britain was not entirely in control, and, will examine the extent to which Britain did retain control, if it did at all. It will look at the pressures the British government had to deal with, for example, pressures from the UN to end British imperialism, pressures from the US, and pressures from other members of the Commonwealth, as well as from the rest of Europe. It will examine the strength of colonial nationalism and the extent to which this took the control of decolonisation in Africa away from Britain, or at least forced the British government to change and adapt its policy in order to cope and deal with this threat. This essay will look at pressures at home in Britain, from members of the government and those in opposition as well as British public opinion, and the extent to which this affected Britain’s policy over decolonisation. It will also look at the impact and influence that the process of decolonisation being pursued by other European imperial powers in Africa had on Britain’s decolonisation policy. It will look at how much the desire of Britain to maintain its role as a world power, and maintain, for example, the special relationship with America, and its position in the Commonwealth, had on British policy over decolonisation and whether this desire led to Britain pursuing a policy direction which it otherwise would not have done. Finally, having examined all these pressures and events which affected Britain’s decolonisation policy in Africa, this essay will attempt to examine to what extent Britain was, or was not, able to retain control over this process, and affect it in a way which was acceptable to Britain. It will then try and make an assessment, whether or not Britain did retain control over decolonisation in Africa in the period from 1959 to 1964, and, if Britain was in control, the extent of this control.
