What’s the association with the animal that ends up being a woman Why bring up animals here?

Factors of communication Essay

Own working practice can affect children and young people’s development in many ways. Children learn trough impersonation, so it is important to always keep in mind that they need to have good role models. When I am working with children, I always remember to be encouraging and trust worthy. When working with children I’m always evaluating and noticing them so that I will be able to suggest for any child and their requirements by adapting the activities for them. It is very essential for me to observe the children that I’m working with competently, so I will know what activity I can plan for them, because sometimes some children might find the activity uncomplicated and get bored. Carers are the children’s role models and they should give them examples to pursue and affect their development in a good way. Shouting can influence a child’s development so when I’m with them I should always remember not to yell. If I am always shouting, children might not ask me any questions as they panic that they would be shouted at or even worse they might start copying me and develop a shouting habit. I have to shield the children from difficult situations when working with them and to always be aware, that is why when there is a problem I share it with my colleagues so we can deal with it and any other difficulties that may arise. While operating with the children I always provide important aspects of care, have good relationship with my colleagues, mind my language, possess suitable material and equipment, and have an appropriate behaviour. Read more: Explain how children and young people’s development is influenced by a range of external factors essay When my teammate and I are doing an activity and crafts in the nursery some of the children might find it harder than other children to use scissors to cut out paper, this might lead the child to be disappointed, get bored and sometimes they end up not wanting to take part in the activity, so to improve those children out we give them proper scissors for those who have more difficulties gripping normal ones. This way our children can proceed together as a group with the activity that has been stated. There are other materials that assist a child’s development and help them take part in the activities, like pencil grips, triangle shaped colours and many more. That  is why it’s very important to have quality equipment, know what they’re for and how to apply them. I must always keep in mind that not all children develop the same way, some may require more time whilst others may need less, that’s why it’s important to be tolerant and regard the child’s personal needs. So I should always remember to use appropriate equipment, be skilled and accomplished in my job to make it easier in children’s development. Reference: Tassoni, P., Beith, K., Bulman, K., Griffin, S. (2010). Pearson Education Ltd. Children & Young People’s Workforce. Essex: Heinemann pg. 81-95 Explain how institutions, agencies and services can affect children and young people’s development: Institutions, agencies and services can affect children development in many ways. If there are good components that meet with the children needs this off course will help a lot in there development. Some of the children might have some sort of disability so it is important for the institution to have appropriate equipment and skilled carers. Institutions must always meet the needs of the children either if they are socially, emotionally, physically and intellectually. This might include people like teaching assistants or advisors to provide support and train staff. Youth justice this is based on children with behavioural problems these people will work with them and also social workers to help them. Social workers are there to help vulnerable children and young people and their families this might include children on the child protection register or disabled difficulties. They provide teachers and practitioners with aimed support programmes for that child once they have identified the child’s needs. Some institutions also provide specialist nurses who support for the family and child especially if that child suffers from medical conditions that need specialist care and also health visitors come under this title for measuring and assessing a child’s development. As well as a psychiatrist, a doctor who is trained in mental health problems. This person works alongside other professionals to help diagnose or support children and young people with mental health problems. They have also a Physiotherapist, this professional help the children with their movement especially those who have little or no movement. They are trained to get the maximum movement and skill level. In a well equipped environment children can develop important factors such as emotional development, social and interactive development, self development and much more. Though it is always important to have the right components and safe equipment, it is also very important that the children are always supervised by a responsible and skilled carer. Carers in an institution or agency should always be professional and responsible. They should always keep in mind that they need to create a safe and nonthreatening environment, should always monitor closely the reaction of children, keep records and be careful and follow good practice when using any type of equipment. Like this they are helping in the children development while keeping them safe. Reference: Tassoni, P., Beith, K., Bulman, K., Griffin, S. (2010). Pearson Education Ltd.

Educational Technology Essay

Educational technology is defined as the study which involves ethical practices that aid in learning process as well as performance improvement by the use of technology. Technology is usually created and managed when one is using. The term also involves the theories of instructions and learning. Instructional theory embodies the systems and all processes that aid in learning. It also embodies other systems that are used in the development of the capabilities that humans have. The definition of educational technology defines the tools that are used to advance the learning of a student. Education technology has other braches and one of them is instructional technology that is defined as the practice and theory of designing, developing, managing and evaluating resources that are used in learning. It is considered to be part of education technology because it covers its aspects. It is said to be a growing field of study that uses technology to solve the problems that keep on occurring in the learning environment. It is not popular because it has faced resistance from administrators as they argue that technology is not good in class environment. (Elaine Wilson 2005, p 360) Since it offers solutions to the educational problems analysts say that it is important to use it. The main aim of instructional technology is to remove instructions from humans. Analysts continue to say that education needs humans to intervene at one point or the other. There are many instructors that are in the market and their work is to develop materials that facilitate long distant learning for students around the world. They develop e-learning tools with the help of experts in the field. In this context technology refers to the materials that humans use in the process of learning or systems as well as the techniques and organization methods that are used. The modern materials that are in use today include projectors, calculators and portable computers. There are very many people that use the method as a form of learning and most of them are teachers and learners. The use of educational technology can be considered as applied science. The reason why it is so is because technology is a science. According to research, an educational technologist is one who can change education that is basic and prove that that very education is science applied in the process of learning and issuing instructions. The history of educational technology is not very clear but according to Alison Pickard 2005 p. 178, Several decades have passed and the evidence of education technology tools has not transformed the learning that takes place in the classrooms. It also has no positive influence on the people that use the method as a way of learning. Another factor is that the history of education technology has evolved very fast and the facts about its history are not clear. There are three schools that are believed to provide the theoretical framework for educational technology. They are cognitivism, constructivism and behaviorism. Each of the schools is present but what has changed is the evolution of the literature that is used today. Behaviorism is a framework that was used with animals to carry out experiments of learning because the animals are said to imitate humans. This type of theory has lost favor but is still used today. There are contributions that it brought to the development of education technology. One is the fact that programmed instruction has been developed. The behavior of humans change because of the environment the learning takes place. Cognitivism is what has brought changes of perception to the learning of today. Since learning has undergone changes many educators view learning differently. This type of theory focuses on the explanation of how the brain promotes learning. It was brought about by human brain but since it has undergone evolution new models of cognitivism have been developed. These new models are said to have contributed much to the development of computer based education technology. The subjects that this theory has made debatable are the areas of information processing and cognitive load. Constructivism is another theory that educators started to consider during the 1990s. The reason that led to this was because learners construct their own interpretation of new information that they receive and as they with one another. This kind of theory requires learners to use the knowledge that they have together with the experience that they have in order to adapt new learning skills. This theory has made sure that there are learning instructors in place and they guide others to generate knowledge of their own. The educators in this theory ensure that the experiences from learning are related to concepts that are usually taught. There are some benefits that are associated with educational technology. It is the instrument that has been used to take education to another level that it has never been before. This is because according to research education can be measured by the results that it produces. The outcome of the results has shown some improvement in the sector of education thanks to the technology that the system has embraced. There are specific benefits that the system offers. One is the ease at which the materials for the course can be accessed. Most courses have websites and instructions attached for easy access and use. This has made the work of the learners to be easy as they do not have to physically go to school to access information as they can do this at home. The materials that are used to study are also easily accessed. Another benefit is that those who use the system are motivated to learn. This is because the system is created in such a way that it provides feedback immediately and this is a form of correction to the mistakes the student might make in the course of learning. In addition the computer is patient and cannot make a judgment over the student. This is a source of motivation for the student. According to research that was carried out by Natasha M. Speer 2005, p. 380 those who use the system as a way of learning take less time to study a particular course and develop positive attitude towards the use of computers. Widening participation is also another factor that is considered beneficial. This is because the materials that are used for learning are accessible over a wide distance and hence encourages participation. Education technology improves the skills in writing of a student. This is because the system has tolls that help the student to edit the work that they have written and this in turn improves the writing skills. They can also be able to exchange information that is to be edited. Subjects have been made easy to learn with the software that has been developed. There has been an increase in the software that has been developed in order to make learning an easy process especially for teenagers and children. The software contains graphics and simulators that are attractive to look at and are appealing to the eye. Integration is also another benefit of education technology. This is brought about by the fact that technology integrates learners as they are guided by technology. (Maryl Gearhart 2004, p. 310) In conclusion, technology plays a big role in the education that takes place in the modern world today. The use of technology has made it easy for learning to take place and has increased its reliability. This is because the technology helps the students to develop new skills, ideas and solving problems that occur. Since it has become popular, it has also faced some criticism. Some say that this kind of learning does not provide physical interaction of the people that are involved in the process. Another thing is that the information that the system has depends on humans and they can make errors in the process of developing. Work cited Alison Pickard.

Asymmetric information and market disequilibrium Essay

Asymmetric information and market disequilibrium - Essay Example Evidences state that asymmetric information has resulted in adverse selection and under provision or lack of trade (Cawley & Philipson, 1999, p.827). In the real markets cases often arise when the seller knows more about the product being traded than the buyers. As for example in case of second hand car market, the seller knows more about the car than the buyer. It may be the other way round also where the buyer posses more information than the sellers as for example in insurance market, the buyers of the insurance usually is more aware about their risks than the insurance company selling them the insurance. Labor market can be considered as another case where a labor trying to get a job is more aware of the fact that how able he is or she in convincing the employer to bag the job (Economics of organization, slide 4-6). The market of used car will be used as a model where the asymmetric information leads to the absence of trade in that market. The prediction of the conditions for the used cars is very hard to estimate. Various parameters to judge the conditions may be appearance of the car, existence of otherwise of a guarantee with the car, date of manufacturing and so on. But here the assumption will be that the buyer has only two sets of expectations or information in his mind that is the car is either good or the car is bad. The potential buyer also does not have the determination power of the condition of the car in ex ante situation (Economics of organization, slide 6). The seller is well informed about the condition of the car. If the car is in bad condition, the seller does not have the incentive to reveal the fact (Asymmetric Information, n.d). The willingness of the seller to sell a product is expressed in terms of reservation price. The reservation price of the seller is the price that the seller would accept for the object (Adverse Selection, n.d., p. 1) and it depends obviously on whether the car is good or bad. The reservation price of the seller is provided in the table below: Reservation Price Good condition Bad Condition $ 10, 000 6,000 Table 1. Similarly the buyers also evaluate the condition of the car which is also their reservation price (Onuma, n.d., p. 3). Now common information available to everyone is that half the sellers are selling good cars and half the sellers are selling bad cars. The reservation price of the buyer is provided in the table below: Reservation Price Good condition Bad Condition $ 11,000 7,000 Conjecture of the buyer In case of a risk neutral buyer the maximum amount he or she willing to pay for a used car is given in the expectation calculation of the buyer as given by, , Where E (B) = Expected buying price & probability of half of the sellers selling bad cars= probability of half of the sellers selling good cars= Now if the buyer gets to know about the reservation price of the seller, then he or she will work out the price calculation and will accordingly find that at the price only the selle r of the bad car will be willing to sell the car because the sellers of only bad car’s reservation price is above $ 9,000 and the seller of the good cars’

Business Marketing - Essay Example The web sites chosen are the online book stores of firstandecond.com, amazon.com, barnesandnoble.com, and oxfordbookstore.com. These web sites have been chosen as to provide a wider perspective of online stores, since it incorporates the pioneer and the leader of online book stores amazon.com, a large publishing house in Barnes and Noble, a medium online retailer in Oxford Books, and a small book reseller in firstandsecond.com. The diversification of product range in the website of Amazon.com is wide, so that the website no longer resembles an online book seller, but an online store that caters to books, entertainment products and a range of other products. In a similar manner there is product diversification with Barnes and Noble into entertainment products. On the other hand there is no product diversification with Oxford Books and firstandsecond.com. Due to the product diversification in with Amazon.com and Barnes and Noble, there is more clustering in the main page of the website, and so the design of the website Oxford Books or firstansdsecond.com for product display is more suitable for the web site to be developed. In both these sites the central section of the first page carries product promotion message and below that are clear images of the products on offer, with a peel in facility for more details on the products, which includes the price. This enables a customer to get more information on the range of products available before exercising a buy option. On the left are options that enable a customer to gain more insight into the company, its history and policies and the like. On the right side of the first page are promotion information like promotional offers on products, new arrivals and specific topics on which books are available. In all these web sites the option for multiple purchases exists and so there is a shopping cart to which the products chosen can be added and the list of

World Trade Organisation Essay Example | Topics and Well Written Essays - 3000 words

World Trade Organisation - Essay Example Then after the organisation's final decision a panel is set to hear the issues raised. This panel encourages countries to resolve disputes themselves and if necessary the panel gives compulsory decisions which can be appealed. If a country turns down the appeal then it is forced to change its trade policies or World Trade Organisation authorizes those countries harmed by the policies to impose retaliatory measures to the offending country. These measures include an increase in tariffs, use of subsidies or any other protectionist measure. These measures are a clear indication that World Trade Organisation is based on mercantilist principles and is not aimed at bringing unity among member countries by encouraging free trade. The organisation has principles governing its activities like the non discrimination principle, the reciprocity principle and the transparency principles but it rarely uses them. Mercantilism is termed as an economic assumption that makes a country prosper. It mostly depends on the capital supply and the volume resulting from international trade. Capital in this theory is represented by silver, gold and any other trade value which the country has. The capital is increased by creating a positive balance in trade with other nations. The country plays protectionist measures whereby it protects its domestic firms against competition from foreigners by use of tariffs, subsidies and quotas. Mercantilism contains policies that the given countries should follow. For example, mercantilism allows a country to utilise its soil for agricultural activities, mining and manufacturing of products. It also allows a country to use its raw materials to manufacture goods since it assumes that finished goods have more value than the materials. This rule also discourages the importation of foreign goods and also says that no importation should be made if the goods are produced in the country. Mercantilism encourages countries to obtain imports that are indispensable first in exchange of other locally produced goods but not silver or gold. This practice encourages countries to seek to have a large working force because it is one of the policies in mercantilism. Countries are also allowed to seek opportunities for selling excess manufacturers to the foreign firms in exchange of gold or silver. Mercantilists assume that only one country should benefit while the other countries should loose in the process. They also believe that any policies that benefit one country can harm the other country by making that country not to experience economic growth thus not helping them to develop. Although most countries practice liberalism mercantilist principles are still common in other countries. The liberalism method has not benefited all trading partners. Countries practicing neo mercantilism have experienced high economic growth compared to countries practicing free tra de. For example, the US and United Kingdom have experienced slow economic growth after adapting free trade. WTO

Talking about the poem Let America be America Again, The New Colossus, Essay

Talking about the poem Let America be America Again, The New Colossus, and the novel Enrique's Journey - Essay Example According toHughes, the author, he is not just representing the plight of most of the African Americans, but also the minority groups the economically disadvantaged folks I am the young man, full of strength and hope, Tangled in that ancient endless chain Of profit, power, gain, of grab the land † (6). Besides showing open criticism to the unfair American life, the poem illustrates a ray of hope that is yet to come in the yet to be achieved American dream, â€Å"†¦America never was America to me, and yet I swear this oath-America will be† (Hughes 8). This poem has been an important agenda in most of America’s discussion about the American dream and how it can be redrafted so that all American people enjoy the treasures of their land. According to the poem, in as much as there have not been successful strategies in the achievement of this dream, a great hope hangs in the air over the probability that at one point in time, this dream will be achieved. The author of the poem makes a declaration that America has to be left to itself; here, he emphasizes that the dream that once was a promise by the country should be left to come by, especially for the pioneer of the land, who decided to seek a home in a place that he could be free. The author notes that, â€Å"America was never America to me† (Hughes8).In his perspective, America is expected to go back and become the great dream according to the way the dreamers put it, â€Å"great string land of love† (Hughes 6). In achieving its dream the way the dreamers wanted the land to be, the author wishes that America can be a home for all people. He notes that the country should not have people that are tyrants and kings or those that have to crush other people in their journey to greatness. The author emphasizes in the repetition that, â€Å"It never was America to me† (Hughes 4). In his assertion, the author of this poem wishes that America embodied

Closing the Youth justice Gap - Essay Example It is for the above reasons and more that we must work together to ensure that the BMER young peoples voices are listened to and heard. There should be an initiative to start a process involving the young people as change agents and their views on crime and community safety to be heard and include them in policy and practice if plausible. The strategies to be followed must make cities safe for one and all. Reasons for a young offender who was repeating his offences and being taken into custody number of times should be explored. It might happen due to the Youth Justice Board agents’ discrimination towards them. The depression and frustration when there is no outlet may turn out in the form of a crime. When these are introduced to Entry to Employment Young people who are on mainstream E2E programmes. Children and young people who offend face particular problems accessing or sustaining engagement with education, training and employment. The pilot, which ran from August 2003 to July 2005 with Hindley Young Offender Institution and local youth offending teams was able to identify these barriers to engagement and highlighted along with poor educational attainment, including basic literacy and numeracy problems. ï€  Some providers being disinclined to provide training to young offenders who may have challenging behavior, poor life skills, such as time and budget management, behavioral issues, a lack of awareness, locally, among providers of how to improve the situation.

Joy luck club Essay Example | Topics and Well Written Essays - 1000 words

Joy luck club - Essay Example The inception of the prologue in the film and the presentation of the film along with its large scaled and detailed camerawork have made the film appear like a river dancing to the tune of wind or fall of words from poetic imagination. This essay intends to focus on the thematic aspect of the film, along with its myriad technical dimensions which provided it a strong and unique perception altogether. THE JOY LUCK CLUB: THE TRAJECTORY Life has different twists and turns, crest and fall and people amid all the complexities and hustle and bustle of life forget to retaliate upon the lost moments of profanity. The film Joy Luck Club captures and upholds different subtle and intimate moments between families and life where subtle and intricate human relations and values operating upon the matrix of myriad social and economic aspects find its profound expression. The film depicts a development of a club formed by four women; it can be seen as a strong discourse of women empowerment depicted within the societal change and structure of contemporary America. The club had a different objective, the members of the club indulged themselves in playing, ‘mahjong’ and over the span of years they have involved themselves in telling and sharing the stories of their lives with each other. Their life trajectory speaks particularly about a societal transition in America. And, various dimensions of Chinese immigrants to America surface out with full force into the plot of the film. The women discuss their passage to America from China, their pursuit and dream, their desire and disappointment. The way they remarried in America for a better life and gave birth to their children on this land itself are very much contextual. Another theme of the film is the space or vacuum that evolves due to generation gap and a space which forms due to the transition of culture and inter-cultural exchanges against the cosmopolitan backdrop. One can find highly ambitious mothers setting hi gh hopes and keeping high faiths upon their daughters who are about to replace them. The daughters face a lot of troubles treading down the paths of success full of anxieties and a stark feeling of inappropriateness that haunts them. Moreover, through the course of understanding and empathizing with each other, the mothers and daughters at the Joy Luck Club are able to bridge their differences (Johnston, â€Å"FILM / The tears of living dangerously: Wayne Wang called Oliver Stone's films evil; Stone called Wang's boring. The novelist Amy Tan brought them together. By Sheila Johnston†). The film is initiated with a short prologue by June; a narrative which is very poetic in appeal and followed by June’s farewell party at San Francisco and her plunge to reunite with her long forgotten twin sisters at China indicate a sense of unification with one’s forgotten root that build the essence of the theme operating within the film. There are also guests at Joy Luck Club, mainly constituted by the mothers, their daughters and the friends and relatives. Each of the members narrate their story of conflict, dream and struggle in the alien land of the United States of America which builds a strong discourse upon the nature of immigration and life of the immigrants in America. The most fascinating technical aspect of the film ‘The Joy Luck Club’ is its cinematography and tight-lipped editing apart from

Healthcare Organization Essay Example for Free

Healthcare Organization Essay Healthcare organizations are now stepping up their strategies in improving their programs and systems. Business and marketing are collaborated to boost resources which are expected to serve as a benefit to their clients. Considering the fact that HCOs consist of social factors and societal influences, it is vital for healthcare practitioners and most importantly the management to build a stronger foundation and forecast plan for their courses of action. The advent of technology and the tight competition in the market may apparently positively of negatively impact HCOs. Hence, given the appropriate concepts and strategies armed with proper implementation of designed concepts, any HCO is most likely to survive (Longman, 2005). Simple concepts and theories of marketing and organizational behavior will help HCOs in circumstances like risk management, conflicts, human resources and other forms of the like. Analysis Communication is one of the most important fields in any organization. Given the fact that an organization is composed of individuals with varied characteristics and personalities, it is vital for these beings to have a common channel that will serve as a bridge in closing deals and team participations. Technology is perhaps the focal element in creating a robust and efficient means for communication (Mascarenhas, 1995). HCO may take advantage of this communication-related improvement by acquiring the most updated and most effective tools in running the organization. The most recent sparks of idea which proved to be of great help to healthcare practitioners are e-Prescription and e-Documentation. It paved a way for HCO to make their services become more available not only to clients within their vicinity but globally. Through the help of the internet, they are able to endorse their products and their services with just a click away. E-Documentation has helped every HCO evidently because it helped in the documentation of patient records and made these files available in a secure database which enabled patients to track their health-related records hassle-free. These developments in communication have even made HCOs all over the world collaborate and communicate efficiently and more rapidly. Earning them the all the time that they need to conduct business. As for the case of the Veterans Health Administration, the entity is fortunate enough to receive help from the state. Even though the benefits that the latter receives continue to be criticized, their organizational, planning and marketing strategy proves to be surfacing in high grounds. They see to it that their programs are not only available and accessible to a popular few but for those who are qualified for their services. Thus, they would need a little improvement with regard to how they generate resources for their facilities. Especially since they are dealing with a continuum of patients that will grow each year, they should employ updated amenities and hear the concerns of their clients. They should make their managerial actions transparent to the public and employ activities that will drive investors to donate for their cause. Conclusions and further remarks Having technology commence in a swift sense is an opportunity for healthcare organizations to make the most out of their capacities.  Citing the problem on VHA, they lack in communication efficiency which in essence should be improved so as to keep their clients’ trust on their ability in healthcare. Healthcare organizations even so need to integrate organizational strategies especially since they are deal with the society (Karlawish, Fox, Pearlman, 2002). Financial stability is also important which is why they should learn how to implement economy-inclined policies and strategies for their philanthropically tending organization.

Effect of Short Range Correlation

Effect of Short Range Correlation The effect of short range correlation on the nuclear charge density distribution, elastic and inelastic electron scattering coulomb form factors of 16O nucleus Abdullah S. Mdekil Abstract The effect of the short range correlation on the charge density disribution, elastic electron scattering form factors and inelastic Coulomb form factors is studied for the two excited states (6.92 and 11.52 MeV) in is analyzed. This effect (which depends on the correlation parameter) is inserted into the ground state charge density distribution through the Jastrow type correlation function. The single particle harmonic oscillator wave function is used with an oscillator size parameter The parameters and are considered as free parameters, adjusted for each excited state separately so as to reproduce the experimental root mean square charge radius of In inelastic coulomb (longitidinal) form factors of 16O, two different models are employed for . In the first model (model A), is considered as a closed shell nucleus. Here, the model space in does not contribute to the transition charge density, because there are no protons outside the closed shell nucleus . In the second model (mo del B), the nucleus of is assumed as a core of with 2 protons and 2 neutrons move in and model space. It is found that the introduction of the effect of short range correlations is necessary for obtaining a remarkable modification in the calculated inelastic Coulomb form factors and considered as an essential for explanation the data amazingly throughout the whole range of considered momentum transfer. Keywords: charge density distribution, elastic charge form factors, inelastic longitudinal form factors, short range correlation. 1-Introduction Electron scattering provides more accurate information about the nuclear structure for example size and charge distribution. It provides important knowledge about the electromagnetic currents inside the nuclei. Electron scattering have been provided a good test for such evaluation since it is sensitive to the spatial dependence on the charge and current densities [1, 2, 3]. Depending on the electron scattering, one can distinguish two types of scattering: in the first type, the nucleus is left in its ground state, that is called elastic electron scattering while in the second type, the nucleus is left on its different excited states, this is called inelastic electron scattering [4, 5]. In the studies of Massen et al. [6-8], the factor cluster expansion of Clark and co-workers [9-11] was utilized to derive an explicit form of the elastic charge form factor, truncated at the two-body term. This form, which is a sum of one- and two-body terms, depends on the harmonic oscillator parameter and the correlation parameter through a Jastrow-type correlation function [12]. This form is employed for the evaluation of the elastic charge form factors of closed shell nuclei and in an approximate technique (that is, for the expansion of the two-body terms in powers of the correlation parameter, only the leading terms had been kept) for the open and shell nuclei. Subsequently, Massen and Moustakidis [13] performed a systematic study of the effect of the SRC on and shell nuclei with entirely avoiding the approximation made in their earlier works outlined in [6-8] for the open shell nuclei. Explicit forms of elastic charge form factors and densities were found utilizing the fac tor cluster expansion of Clark and co-workers and Jastrow correlation functions which introduce the SRC. These forms depends on the single particle wave functions and not on the wave functions of the relative motion of two nucleons as was the case of our previous works [14-20] and other works [6,21,22]. It is important to point out that all the above studies were concerned with the analysis of the effect of the SRC on the elastic electron scattering charge form factors of nuclei. There has been no detailed investigation for the effect of the SRC on the inelastic electron scattering form factors of nuclei. We thus, in the present work, perform calculations with inclusion this effect on the inelastic Coulomb form factors for closed shell nucleus. As a test case, the is considered in this study. To study the effect of SRC (which depends on the correlation parameter on the inelastic electron scattering charge form factors of considered nucleus, we insert this effect on the ground state charge density distribution through the Jastrow type correlation function [12]. The single particle harmonic oscillator wave function is used in the present calculations with an oscillator size parameter The effect of SRC on the inelastic Coloumb form factors for the two excited states (6.92 and 11.52 MeV) in is analyzed. 2. Theory Inelastic electron scattering longitudinal (Coulomb) form factor involves angular momentum and momentum transfer and is given by [23] (1) where and are the initial and final nuclear states (described by the shell model states of spin and isospin ), is the longitudinal electron scattering operator, is the center of mass correction (which removes the spurious states arising from the motion of the center of mass when shell model wave function is used), is the nucleon finite size correction and assumed to be the same for protons and neutrons, A is the nuclear mass number, is the atomic number and is the harmonic oscillator size parameter. The form factor of eq.(1) is expressed via the matrix elements reduced in both angular momentum and isospin [24] (2) where in eq. (2), the bracket ( ) is the three- symbol, where and are restricted by the following selection rule: (3) and is given by The reduced matrix elements in spin and isospin space of the longitudinal operator between the final and initial many particles states of the system including configuration mixing are given in terms of the one-body density matrix (OBDM) elements times the single particle matrix elements of the longitudinal operator [25] (4) where and label single particle states (isospin included) for the shell model space. The in eq. (4) is calculated in terms of the isospin-reduced matrix elements as [26] (5) where is the isospin operator of the single particle. (6) The model space matrix element, in eq. (6), is given by (7) where is the spherical Bessel function and is the model space transition charge density, expressed as the sum of the product of the times the single particle matrix elements, given by [26]. (8) Here, is the radial part of the harmonic oscillator wave function and is the spherical harmonic wave function. The core-polarization matrix element, in eq. (6), is given by (9) where is the core-polarization transition charge density which depends on the model used for core polarization. To take the core-polarization effects into consideration, the model space transition charge density is added to the core-polarization transition charge density that describes the collective modes of nuclei. The total transition charge density becomes (10) According to the collective modes of nuclei, the core polarization transition charge density is assumed to have the form of Tassie shape [27] (11) where is the proportionality constant given by [14] (12) which can be determind by adusting the reduced transition probability to the experimental value, and is the ground state charge density distribution of considered nuclei. For the ground state charge densities of closed shell nuclei may be related to the ground state point nucleon densities by [28, 29] (13) in unit of electronic charge per unit volume (e.fm-3). An expression of the correlated density (where the effect of the SRCs is included), consists of one- and two-body terms, is given by [13] (14) where is the normalization factor and is the one body density operator given by (15) The correlated density of eq. (14), which is truncated at the two-body term and originated by the factor cluster expansion of Clark and co-workers [10-12], depends on the correlation parameter through the Jastrow-type correlation (16) where is a state-independent correlation function, which has the following properties: for large values of and for It is so clear that the effect of SRCs, inserted by the function becomes large for small values of SRC parameter and vice versa. The one-body term, in eq. (14), is well known and given by (17) where is the occupation probability of the state and is the radial part of the single particle harmonic oscillator wave function. The two-body term, in eq. (14), is given by [13] (18) where (19) The form of the two-body term is then originated by expanding the factor in the spherical harmonics and expressed as [13] (20) where (21) and is the Clebsch-Gordan coefficients. It is important to point out that the expressions of eqs. (17) And (20) are originated for closed shell nuclei with where the occupation probability is 0 or 1. To extend the calculations for isotopes of closed shell nuclei, the correlated charge densities of these isotopes are characterized by the same expressions of eqs. (17) and (20) (this is because all isotopic chain nuclei have the same atomic number but this time different values for the parameters and are utilized. The mean square charge radii of nuclei are defined by (22) where the normalzation of the charge density distribution is given by (23) 3-Results and discussion The ground state CDD is calculated by eq.(13) together with eqs. (14), (17) and (20). The calculated CDD without (with) the effect of the SRC [i.e., when the correlation parameter is obtained by adjusting only the parameter (the two parameters and ) so as to reproduce the experimental root mean square (rms) charge radii of nuclei under study. The elastic electron scattering charge form factors which is simply the Fourier transform of the ground state CDD. In Fig. 1, we compare the calculated CDD [Fig. 1(a)] and elastic charge form factors [Fig. 1(b)] of with those of experimental data (the open circles). In Fig. 1, we compare the calculated CDD [Fig. 1 (a)] and elastic charge form factors [Fig. 1 (b)] of with those of experimental data (the open circles). The dashed curves are the calculated results without the inclusion of the effect of the SRC obtained with and fm. The solid curves are the calculated results with including the effect of the SRC obtained with fm-2 and fm. It is important to point out that the parameters and employed in the calculations of the dashed and solid curves are chosen so as to reproduce the experimental rms charge radius of Fig. 1 (a) illustrates that the calculated CDD of the dashed curve (without the effect of the SRC) is in such a good agreement with that of the experimental data, and the solid curve (with the effect of the SRC) is not in such a good agreement with that of the experimental data, e specially in the central region ( fm) of the distributions. The inclusion of SRC has the feature of reducing the central region of the distribution as seen in the solid curve of this figure. Inspection to the Fig. 1 (b) gives an indication that the solid curve is better describing the experimental data than that of the dashed curve, particularly in the region of momentum transfer fm-1. The rms charge radius calculated with the above values of and is 2.621 fm, which is less than the experimental value by 0.097fm, which corresponds to a decrease of nearly 3.6 % of the experimental value. Fig. 1. The calculated CDD and elastic charge form factors are compared with those of experimental data. The dashed curve corresponds to the values for the parameters and fm, the solid curve corresponds to the values for the parameters fm-2 and fm while the open circles and the triangles in Figs. 1 (a) and 1 (b) are the experimental data taken from [30] and [31], respectively. The effect of the SRC on the inelastic Coulomb form factors is studied for the two excited states (6.92 and 11.52 MeV) in. Core polarization effects are taken into consideration by means of the Tassie model [eq. (11)], where this model depends on the ground state charge density distribution. The proportionality constant [eq. (12)] is estimated by adjusting the reduced transition probability to the experimental value. The effect of the SRC is incorporated into the ground state charge density distribution through the Jastrow type correlation function [12]. The single particle harmonic oscillator wave function is employed with an oscillator size parameter The charge density distribution calculated without the effect of the SRC depends only on one free parameter (namely the parameter), where is chosen in such away so as to reproduce the experimental rms charge radii of considered nuclei. The charge density distribution calculated with the effect of the SRC depends on two free parameters (namely the harmonic oscillator size parameter and the correlation parameter), where these parameters are adjusted for each excited state separately so as to reproduce the experimental rms charge radii of considered nuclei. Two different models are employed for. In the first model (model A), is considered as a closed shell nucleus. In this model, the proton occupation probabilities in are assumed to be and Here, the model space in does not contribute to the transition charge density [i.e. ], because there are no protons outside the closed shell nucleus . Accordingly, the Coloumb form factors of come entirely from the core polarization transition charge density. In the second model (model B), the nucleus of is assumed as a core of with 2 protons and 2 neutrons move in and model space. In this model, the proton occupation probabilities in are assumed to be and Here, the total transition charge density [eq. (10)] comes from both the model space and core polarization transition charge densities. The OBDM elements of are generated, via the shell model code OXBASH [32], using the REWIL [33] as a realistic effective interaction in the isospin formalism for 4 particles move in the and model spac e with a core. In Table 1, the experimental excitation energies (MeV), experimental reduced transition probabilities (fm) and the chosen values for the parameters and for each excited state (used in the calculations of model A and B) in and are displayed. The root mean square (rms) charge radius calculated in both models with the effect of SRC is also displayed in this table and compared with that of experimental result. It is evident from this table that the values of the parameter employed for calculations with the effect of SRC are smaller than that of without SRC ( fm) . This is attributed to the fact that the introduction of SRC leads to enlarge the relative distance of the nucleons (i.e., the size of the nucleus) whereas the parameter (which is proportional to the radius of the nucleus) should become smaller so as to reproduce the experimental rms charge radius of the considered nuclei. Inelastic Coloumb form factors for different transitions in are displayed in Figs. 1 and 2. The calculated inelastic form factors obtained with model A are shown in the upper panel [Figs. 1(a)-2(a)] of the above figures whereas those obtained with model B are shown in the lower panel [Figs. 1(b)- 2(b)] of the above figures. It is obvious that all transitions considered in, presented in the above figures, are of an isoscalar character. Besides, the parity of them does not change. Here, the calculated inelastic form factors are plotted versus the momentum transfer and compared with those of experimental data. The dashed and solid curves are the calculated inelastic Coloumb form factors without and with the inclusion of the effect of the SRC, respectively. The open symbols are those of experimental data taken from [34, 35]. Table1.

Creation of a Web Based Business Property Website

Creation of a Web Based Business Property Website Isidoros Ioannou Creating an Innovative Business Nowadays, the cost of living has been increased significantly in the majority of the European countries. This raise can be reflected on the high amount of money spent by people for renting flats to reside. Especially, UK is the country that charges the highest rent rates to tenants among the other European countries (Guardian, 2015). It is inevitable for several groups of people, particularly students and young professionals to seek and rent a room in a flat share. The process of finding the suitable property and the appropriate future housemates is not easy at all. Living with other people is usually a complicated and difficult situation, because peoples characters are different and not everybody matches with each other. There are several aspects to consider when someone is choosing a property to rent or flat mates to live with. Most of the times people do not respect your privacy and this can lead to various conflicts (BBC ,2013), (thefirstpint, 2010). As a result, UK citizens spend every year a serious part of their income to find a residence that could meet their preferences and countless time to search for important information, such as potential housemates. In order to alleviate the problem of the significant amount of time and money invested for the process of finding a flat and suitable flat mate, a corresponding service provider needs to be developed. The company will focus on helping especially students and young professionals, since these two categories of humans are noticed to search usually for renting properties. The company named easyproperty would be web-based it would give the opportunity to their customers to search for the more suitable people to share a common property, according to their preferences. Customer will have to register first and submit their preferences and characteristics. These would be for example, occupation, gender, nationality, age, habits, interests, the amount of money they could afford to spend, their preferred location, etc. They could have also the capability to prioritize some of their input preferences, in order to the matching algorithms could give more effective results regarding their preferences. The customer could then perform a search on the website of the company. Its search mechanism will find the people that match mostly the customers preferences and concurrently will provide in the same page property recommendations from the databases of various agencies. The capability of altering the location and other attributes before search will be also included. The people list and property list will be sorted based on the people and properties that matched more successfully the persons inputs that conducted the search activity. However, the property list will be displayed with some peculiarities. In other words, for properties that nearly showed the same percentage of matching with the user, priority will be given to them that contain already residents. For instance, if a house consists of two rooms and only one is vacant, this house will be in a higher position in the list, compared to other houses. Currently in the market some competitors exist that offer similar services. The most renowned are SpareRoom.com, Rightmove.co.uk and Zoopla.co.uk. The technologies that these competitors use and the ones that the suggested company is going to use will be analyzed in detail in the following chapter. First of all, the immediate competitor of the authors suggested company is SpareRoom.com. It allows clients to perform searches for suitable flats or flat mates based on their preferences and characteristics. spareroom.com provides its services across all the UK and USA and it is the pioneer on its activity field in the UK since it counts nearly 6,499,202 registered users (spare room, 2017). The user can also register to the website and upload advertisements about suitable rooms or flat mates that he wishes to find. Other users can review these advertisements by performing search tasks to the systems database. One of the drawbacks that spareroom.com has it possess its own database system. This means that the searches are limited to the properties that are included only in its database. In addition, due to spareroom.com targets a wide range of the market, it is difficult to focus on certain categories of people, which in this case are students domestic and international among with you ng professionals. The operation and success of easyproperty will be based on its attempt to tackle the drawbacks of spareroom.com. It will use databases of each areas local estate agencies to offer more options to its users. The options will be mostly compatibles to the two fore mentioned categories of people that the company aims to target. On the other hand, the other remaining competitors, rightmove.co.uk and zoopla.co.uk provide only the option to users to search for the suitable room. They do not offer options for the user to search for a suitable flat mate. Both also use databases from local estate firms they cooperate with and offer a wide range of available property choices. Particularly rightmove.co.uk provides renting and sale services only in the UK while provides also selling services across Spain and France. (rightmove, 2017). Likely zoopla.co.uk provides renting and selling features only in UK but provides selling features for a wider domain of countries, nearly all over the world (zoopla, 2017). The competition with these companies is noticed on the establishment of cooperation with the local estate firms. The web based firm that the author suggests and will penetrate into the property estate market aims to offer efficient features to students and young professionals who are the main groups who cannot afford to rent a house by themselves and need to share a flat. The service that easy property offers is unique as it offers the opportunity to their users to find the most suitable house mate and at the same time it assists them to choose the most desired property to live. From the description of the services that the company will provide it is conceived that the environment of its activity will be the World Wide Web (WWW). According to Gong and Zhu (2009), the main service that an e-commerce electronic website provides is user registration, query, shopping and communicating online. As a result for our business, a functional e-commerce website would be the ideal choice. An electronic commerce website should equip WWW browse, data server, e-mail service, customer operation system together with web service system and so on software and hardware (Gong Zhu, 2009). In addition, the usability factor is vital for this kind of website, since it determines the intention of the customer to use and exploit the services of the website. The term usability refers to both a set of independent quality attributes such as user performance, satisfaction, and learnability (Green Pearson, 2011). In order to, satisfy these requirements and produce an effective and user fr iendly application, the author chose carefully the components that will constitute the website. The website will be developed using the WordPress Content Management System (CMS). It is a free open source tool that requires little programming experience and various free plugins. It will be integrated with php and HTML 5 web development technologies, since they are scripting languages focused on implementing website pages. They will offer dynamic connections to other websites and great responsiveness when the companys website will be displayed on different devices. This practice would result in a better user experience for the user, thus in a better usability (websitesetup.org, 2017). In addition, the Woo Commerce platform will be incorporated to the website as bridge with the companys server which will help with the data retrieval and manipulation from the server. Regarding the other components that are crucial for the operation and tasks of the website and were mentioned above, the author is going to use the most value for money solutions. For the domain name which will be www.easyproperty.co.uk the namecheap hosting company will be chosen. Other software elements, for example the web server and the business email server are provided also from the same company. The technology of cloud computing is really attractive to the majority of the small and medium size companies, since they are not obliged to invest a significant asset on hardware or software services. Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) (Jula et al., 2014). The service and the maintenance of the infrastructure is the responsibility of the cloud provider. Companies can exploit the high performance and the support that cloud providers offer without spending extra money (Laudon Laudon, 2016). From the four cloud computing service models: Software as a Service, Platform as a Service (PaaS), Infrastructure as a Service (IaaS) and Network as a Service (NaaS), the company will depend on IaaS model for utilizing its data storage. Microsoft cloud will be chosen as the cloud provider. According to Payne and Frow (2005), a very important practice that plays important role in the success of the business is Customer Relationship Management (CRM). It is a practice that if a company implement efficiently, can easily achieve better relationship with its customers and increase the flow of them. The clients will be regularly notified about offers and services by sending those emails that will be stored in the companys database. Finally, the aim of the company is to expand its service by implementing the website into mobile applications. Cross-Platform tools enable the development of applications for multiple mobile operating systems (OS). It allows reusing the same source code for building an application for multiple platforms (Charkaoui, et al., 2014). By using one of the available cross platform tools it will save a lot of time and cost comparing to using native application development tools, since it requires developing separate apps for the different mobile OS and in a different programming language. Business model is the content, the structure and the administration of the transactions, which have been designed to create value and to exploit the various business opportunities. (Zot Amit, 2011). It explains the insight that a business should have in order to achieve revenue by defining its position into the value chain. (Rappa, 2010). According to Ostwalder and Pigneur (2010), the business model describes how an organization can achieve value creation, value delivery and value capture. The authors have also invented the Business Model Canvas which is a tool that organizes all the activities an organization should implement from the initial value proposition stage to the final stage of value capture. It is two dimensional depiction of nine vital blocks that help the organization to fulfill its objectives, achieve its goals and manage its products and resources. The Business Model Canvas contains the tree elements that define the successful activity lifecycle of a company. Value proposition is the activity of designing services and products that would provide value to customers. Value delivery is the activities the business implements for delivering their products and consequently the value to customers and value capture is the way the company has income from the above activities. The Business Model Canvas, as well as the detailed description of each block is discussed below. Â   Â   Figure 1: Business Model Canvas Customer segments Customer segments are the category of people that the company aims to offer value. The targeted audience of the easyproperty company will mainly consists of university students and young professionals, since these categories are most likely to be searching for flat mates in order to share an apartment. Value propositions/creation The value creation or value proposition is an element really important for any business. Any new business that enters the market should offer something unique or provide better services/products from similar organizations, in order to attract customers. The aim of the company is to provide advanced search features for its customer so that they could find the perfect roommate. This is achieved by providing many fields for entering the customer preferences and the ability to prioritize the ones that are more important for them. The next step is to give them a wide list of properties to choose from in various locations. By using the databases from local estate agencies and the advertisements of private landlords, clients have a lot of options to choose from. Finally the company will provide the opportunity for real estate companies to advertise themselves through the companys website. Channels The channels block contains all the means that the company communicates with its customers and these means are used mainly for marketing purposes. Social media like Facebook and Twitter will be used mostly. Then the website will contain all the links for our social media and also information about all the estate companies we cooperate along with links to their websites and social media. In addition, once the company will target students, the universities of each city could provide assistance in promoting the company. Also the student unions of each university. Finally for promoting our company on the web the Google AdWords is going to be used that could offer better positions on their search engine and advertisement. Customer relationships Customer relationships include the means that the company provides for interaction with its clients. The company will use the customer relationship management practice for maintaining close relationship with the customers and provide them with various means to contact. This could be achieved by direct interaction by visiting the companys office. Moreover through the telephone support that it will be provided on a 24 hour basis. In addition through the website or the mobile application by submitting a contact form and by posting on the social media. Revenue streams(Value Capture) In the revenue streams the sources of the companys income are explained. Firstly, the main source of income will be from the agencies and landlords once a client will get in contact with them and agree to rent or buy the property. The agreement process will begin from the website but it will be finalized face to face. Then the agency or landlord will finalize the deal to the companys website and pay the fee, which will be a 10% commission of the first rent. The customer can also cancel the deal and the fee will be returned. All these activities with the agencies will be agreed under contracts. Another source of revenue will be capability of agencies to be advertised through our company. The tool Google AdSense will be used which is operating in pay-per-click manner. Key resources The Key resources are the activities and resources used for developing the Value proposition/creation and for delivering the value to the clients. As resources could be considered first the company staff that will develop the website and is going to support the clients issues later. Another key resource is the staff that will operate the promotion campaign of the company. Finally the information about the properties of the private landlords that will be stored in the companys database and the databases of the estate agencies. Key activities (Value Delivery) Key activities are the most crucial operations for the execution of the companys business plan. This block contains all the tasks for delivering the value which was created in the value creation block. The initial activity is to develop a fully functional website that it will serve all the services explained in the value creation block. The next step is to sign contracts with the landlords and especially with the estate agencies. This is a very important step as the agencies databases will provide the clients with many options to choose. As advertisement and promotion plays an important role for every new established company, assign to a marketing team the promotion of the business is the next steps. Signing contracts with universities for promotion purposes in order to support students searching for apartments belongs also in this step. Finally as the business starts operating the final step is to develop mobile application for providing furthers to our clients to use our services. Key partnerships Key partnerships include the cooperation network of the company. The network will consist of the real estate agencies and the supply of their databases. Moreover, experience promoting agencies, the University staff and students. Cost structure It summarizes the different costs the company has to make for the value creation. In the cost structure, the staff wages and the hardware equipment are included, for example computer infrastructure. Also the cost of hiring a promotion company and flat wages for the domain and the email server. Finally the annual costs of the cloud services (database) and the hosting server should be added. Previous researchers like Rappa proposed a classification of the various business models instead of a detailed description of what each includes. He supports that a business model should just describe how a firm produces revenue based on its position in the value chain. He proposes nine main categories of business model: Brokerage, Advertising, Infomediary, Merchant, Manufacturer, Affiliate, Community, Subscription and Utility model (Rappa, 2000). The proposed business belongs to some of these categories and the reason is explained below. Firstly the company could be classified to the Brokerage model, since its activities focus on the business to customer (B2C) market as it helps customers who are searching for a room to let, to contact the estate agencies that manage the room they wish to rent. In other words it operates as an intermediate between students, young professionals and the real estate agencies. In addition the company charges a fee as commission for every agreement it is achieved between customers and agencies. Particularly, based on the subcategories of the Brokerage model, the company could be described as a distributor as it offers catalogue services and acts as a bridge between customers and agencies. Moreover, it is a search agent as it enables the customer to search properties according to its preferences (Rappa, 2010). The company also could be classified also to the advertising model. The income from the advertisements of the agencies is secondary. The website contains advertises of agencies and n ew entried apartments in the form of banners. Also advertisement messages about new apartments that were inserted and match the users previous searches are sent to the emails of registered users. Finally it could be stated that the company has some characteristics of the Affiliate model. For instance, it enables the client to contact the agency or the landlord, whenever the customer has access to the Internet. Also it charges the agencies that advertise themselves through the website by the pay per click way. According to Timmers (1998) a business mode is an architecture for the product, service and information flows, incorporating simultaneously descriptions of the sources of revenues, description of the actors and the benefits for them. He recognized eleven business models for the operation of the business transactions which are: e-shop, e-auction, e-mall, e-procurement, third party marketplace, virtual communities, value chain service providers, value chain integrators, collaboration platforms and information brokers.

Dickens Ideas On Gentility As Shown Through Great Expectations :: Great Expectations Essays

Dickens criticized the world of his own time because it valued the status of being a gentleman over someone doing a useful job. Those who thought they were gentlemen often mocked ordinary citizens. Show how he achieved these aims through the language used and his description of the way Pip and the other characters behaved in the novel. In his numerous literary works, Dickens strong sense of right and wrong, and his recognition of the many injustices present in Victorian Society are clearly displayed. There is no better an example of these strong set of ideals then those portrayed in his novel, Great Expectations, which tells the story of Pip, a young boy who is initially fooled into believing that material wealth is a substitute for the real moral values a gentleman should posses. However, through the many trials and tribulations he is forced to go through, he is finally able to identify what it means to be a "true gentleman", one that has acquired true wealth and value. It is only then that he is able to see the real meaning behind Matthew Pocket’s wise words, that: "No man was not a true gentleman at heart, ever was since the world began, a true gentleman in manner." (page 175) In Dickens novel, society’s idea of a gentleman is perceived as someone of great affluence and breeding, who did not necessarily posses the moral values and graces a true gentleman should have. After his initial visit to Satis House, Pip was infatuated by Estella’s beauty, wealth, and self importance. He allowed himself to be degraded by her scornful references to his "coarse hands", and "thick boots", not realizing at this point that these factors are unimportant on the route to becoming a true gentleman. At that very moment, he deludes himself into believing that if he were to meet Estella’s interpretations of gentlemanly conduct, that she would regard him as her equal. Unfortunately, he completely fails to recognize the true moral values present in Joe and Biddy, and is attracted instead by a fantasized version of Miss Havisham’s and Estella’s lifestyles. He sees his visit to Satis House as the first link in the long chain of events which will lead to his eventually becoming a gentleman. Dickens leaves the reader with no doubt that position and rank were major contributory factors as to how a person was regarded in Victorian society.

Essay --

Why should Philippine government invest in Nuclear power? What is Nuclear energy? Nuclear energy is the energy released in two different processes, which is nuclear fission and nuclear fusion. Fission is the process of splitting a large atom into smaller atoms while fusion is the process of fusing smaller and lighter atoms into a large atom. The number one use of nuclear energy is to generate electricity. Electricity is generated through a Nuclear Power plant or a Nuclear Reactor. Nuclear reactors produces electricity in a much similar way with other power plants produces electricity. The process on how a nuclear reactor produces electricity is that it produces and controls the release of energy from splitting the atoms of certain elements then the energy released is used as heat, which turns water into steam, and then later on the steam is used to generate electricity. The difference of a nuclear power plant to other power plants is in the process on how the heat is created. Other power plants that run on fossil fuels, burn oil, coal or natural gases generate heat. While in a nuclear power plant, it generates heat by splitting the atoms of certain elements like uranium. Nuclear energy requires a large capital for emergencies, storage systems and containment but it has a lot of benefits and the best energy source in the long run. With the depleting sources, nuclear energy is the only energy source that can satisfy global demand, effectively replace fossil fuels and it is more sustainable than other energy sources. Nuclear energy has no greenhouse or acid rain effects and the fuel is inexpensive. Nuclear energy also provides environmental safety because the process on how nuclear energy is generated is that it is one of the clea... ... of energy is coal and recently the government approved to build 17 coal plant more in addition to 15 existing coal plant. But there are so many bad sides of using coal and there is better alternative for coal, the nuclear power. Since energy from coal is not affordable for many people in the Philippines and cost tremendously to environment through causing greenhouse effect and destroying ozone layer. Even though nuclear power is not risk-free like the event in Fukushima’s failure of nuclear plant, however the danger of climate change caused by greenhouse gas emissions may be more urgent -- and thus make nuclear a better choice than coal form the environment. Even for waste disposal, a typical coal-burning power plant creates over 300,000 tons of waste ash and sludge each year while a typical nuclear power plant generates 20 metric tons of radioactive waste annually
