Argumentative Speech Essay

Argumentative Speech Freedom of Speech We all know what the general meaning of freedom of speech is. But let me tell you a deeper meaning of freedom of speech. Freedom of speech is the right, guaranteed by the First Amendment to the U.S. Constitution, to express beliefs and ideas without unwarranted government restriction. Speech is built in to our lives as a way to communicate with others. That’s why I believe everyone has the freedom and right to speak. Some nations still restrict the people’s right to speak. One of them is North Korea. North Korea is one of the 5 remaining countries that adopt the communist ideology. According to Wikipedia, anybody in North Korea who tries to speak to the public about the government will be sent to labor camps and be forced to work there. Worst case scenario, they get executed. North Korea is not the only country who does this. Myanmar, Nepal, and the rest of the communist countries do this as well. I believe this has to stop for all humans have the same rights and none of us are superior to anyone. It’s also a matter of honoring human rights. There has to be steps taken to ensure that freedom of speech is available to everyone. The first major movement in freedom of rights is the creation of the First Amendment. According to Wikipedia, the First Amendment prohibits the making of any law respecting an establishment of religion, impeding the free exercise of religion, abridging the freedom of speech, infringing on the freedom of the press, interfering with the right to peaceably assemble or prohibiting the petitioning for a governmental redress of grievances. It was adopted on December 15 1791 as one of the Ten Amendments. I believe that from that point on, freedom of speech has been more widespread and movements like that make the world a better place. Democratic countries are the perfect examples of a country that honors the freedom of speech. In a democratic country, the people are the rulers, and the freedom of speech is used by the people to make the country better. The freedom of speech has a significant impact in our social life. For example, without the freedom of speech, we wouldn’t be able to object to something that the people think doesn’t seem right. A few months ago, the workers in Jakarta asked for a minimum wage increase because of rising prices on goods. The workers are using their freedom of speech to express their thoughts to the government. The government finally increased the minimum wages. Another example is without freedom of speech, the government would control the people. The government would make rules that doesn’t honor human rights, like North Korea. I’m sure no one wants that to happen. Some might argue that there should be huge limits on freedom of speech. That freedom of speech should be limited to our society only and that freedom of speech does not cover the right to speak about the government. But think about it, if freedom of speech is limited, we won’t be able to change rules that are made by the government. We won’t be able to change what’s wrong with the rules. A good example is the US right now. Recently the US has been discovered to spy on US citizens and other countries through the internet. This was revealed by somebody who works inside that government. If freedom of speech didn’t exist, the US citizens would have never known that their government was spying on them. But because freedom of speech exists, we are able to know. Countries shouldn’t be able to limit our freedom to speech. We know now how important freedom of speech is. How crucial it is for every one of us. We all have the right to know, we all have the right to tell. We all have the right to protest if something is wrong in the government. We might feel offended by something someone says. We might also offend someone by something we say. But the world has decided that freedom of speech is important, and it has been shown by the creation of the First Amendment. No one should be able to restrict our minds and restrict our rights to speech. There has to be steps taken to ensure our freedom to speech. So far it has been good, but we need more progress. We need to speak out our thoughts. So far the US has been the country that pushes freedom of speech the most. We all have to follow their example and push the rights to speech. I wouldn’t even be talking here if freedom of speech didn’t exist.

A College Degree Is Worth the Effort and Expense Essay

In today’s economy many people wonder if a college degree is worth the time, effort, and expense it takes to complete it. I, a twenty-seven year old who did not think it was worth it when I graduated from high school, have changed my position on the issue. I have had experience in today’s workforce and it is not easy to find a satisfying job with only a high school diploma and it is extremely difficult to find a job with decent pay and any benefits in which you have a chance of advancing in that career. These things are essential for a productive and fulfilling life. I believe that getting a college degree is well worth the time, effort, and expenses. A report by the Pew Research Center found that college graduates make about $550,000 more than high school graduates over the course of their careers (Cass). This shows the significantly larger income opportunities of having a college degree versus only a high school diploma. Imagine the difference of making $465,000 compared to $1,015,000 over a thirty year career? Breaking that down for $465,000 would be $15,500 a year, $1,291. 67 a month, $300. 39 a week, and $7. 51 a hour compared to $1,015,000 or $33,833. 33 a year, $2,819. 44 a month, $655. 68 a week, and $16. 39 a hour. It is a big difference! In today’s workforce we have an increase in unemployment. The unemployment rate in 2010 was 5. 4 percent for people with bachelor’s degrees and less for those with higher degrees, according to the U. S. Bureau of Labor Statistics. Meanwhile, 7 percent of those with associate’s degrees and 10. 3 percent of those with only a high school diploma were out of work (Cass). This shows that obtaining a college degree enhances chances of becoming gainfully employed. Charles Wallace also writes about the demands of our workforce and our need for college education. Wallace quotes a report that â€Å"estimates the economy will create about 47 million jobs by 2018, including 14 million new jobs and 33 million jobs replacing workers who leave or retire. About 33 percent of those jobs will require a bachelor’s degree and another 30 percent will require an associate’s degree or at least some college training. Only a third will be available to people with a high  school diploma or less. † The cost of college has increased more than many other things in today’s society, in fact â€Å"the cost of college has nearly doubled in the past 10 years, while housing costs and the overall Consumer Price Index have risen less than 25 percent† (Cass). However the rewards you can get from college still outweigh the effort and expense at least for now. The government is trying to help ease the burden, â€Å"starting in July 2014, loan recipients will have to devote only 10 percent of their income to loan repayments, rather than 15 percent. And those loans will be forgiven after 20 years, rather than the current 25 years† (Brooks). If the costs continue to rise so dramatically then the costs will eventually begin to outweigh the rewards. However when you look at the rewards you have to look at more than just the financial gains; there are many other rewards to consider such as health insurance, retirement plans, experience with more diverse cultures, and the positive self-improvements that come with college education. As Charles Nelson, writer of the essay, â€Å"Investing in Futures: the Cost of College† states, â€Å"degrees pay off in other ways too. College exposes students to new issues and subject areas; it helps students to consider the value of things that might otherwise seem pointless; college graduates may lead more rewarding lives, being more mentally engaged by their surroundings (333). I believe a college education is a very important investment. It outweighs the costs many times over. College education opens many doors and lasts a lifetime. It increases the ability to understand other societies, helps to explore options that may have never been considered before, and contributes to a greater sense of self fulfillment and self-worth.

Assignment - Essay Example The symbolic interaction theory â€Å"looks at how people interact with one another and communicate with symbols and gestures† (Strong, DeVault, and Cohen, 2007). A good example of symbolism in my family is the setting arrangement at our dinner table. My father who is considered as the head of the family sits at the head of the table, my mother sits at his right side while my eldest sibling sits on his left side. I consider this arrangement as very symbolic since this order defines the powers and influence that each members of my family has. Note that the most powerful figure in my family sets at the head of the table while the second most powerful and perhaps the most influential one which is my mother sits on the right side which denotes that she is second in command. My eldest sibling on the other hand has the privilege of sitting on the left side of my father which apparently made him third in command. Technically, this means that he has authority over me and my younger si ster. The symbolic distribution of power among members in my family defines the roles of each family member. As the head of the family, my father has the responsibility to provide for us while my mother who is second in command takes on the role of a homemaker. Our roles in the family often affects our interaction with society in the sense that our actions are guided by the extent and the limits of the powers that we have in the home. For instance, since my mother is the homemaker, she controls the family budget and she is often the one who gets to decide what things to buy for the house. Since she has control over the family budget, she has more purchasing power as compared to us. As it is, her interaction with the other members of society takes on a different dimension as compared to the other members of the family. When it comes to gestures, my family uses familiar expressions and gestures to convey

Labour rights for illegal immigrants Research Paper

Labour rights for illegal immigrants - Research Paper Example They are forced to work with unscrupulous employers for pittance, denied all benefits and allowances, including holidays and overtime pay, and made to live in constant and morbid fear of being caught and deported back to their countries of origin. Since they are marginalized and without support, they are often exploited by employers who use them as cheap laborers with little reward for their hard and arduous labor. Research Hypothesis: This paper will focus on the increasing number of immigrants that are specifically coming into the United States and the roles they play; both the positive and negative aspects of life in this country as well as to the significant reasons why they need to be supported by the native people here. Introduction: The US has always been a land of great opportunities for people coming from other underdeveloped countries of the world. Thousands of immigrants flock into the US in order to seek a better deal for themselves and their families and to get rid off p overty back home. â€Å"Individuals generally choose to emigrate to countries that are more technologically advanced, have greater resources and offer more opportunities† (Illegal Immigration 2010). But there are several risks and challenges involved. They think that entry into the United States is an end to all their poverty and misery and the start of a new and happy life for them as well as their families. However, the reality is just the opposite, as soon they start to realize that their problems have just begun, in terms of challenging work situations, risks of getting caught and deported and being marginalized in all walks of life when compared with native inhabitants. But the truth of the matter is that over America’s eventful history, the contribution of immigrants in this country has been immense. Most of the people who inhabit the United States have been immigrants at one time or the other, and it is only the North American Indians who could truly and justly call themselves the original inhabitants of this country. All others are immigrants who were lucky to gain immigration status over the course of time. It is believed that there are at least 10 million illegal Immigrants in the United States and their figures are increasing with each passing day. They are mostly employed in works, which require little education and less efficient skill sets. â€Å"Illegal immigrants make up a significant portion of the workforce in key industries. 1.4 million are employed in leisure and hospitality with another 1.7 million in construction and 1.0 million in manufacturing. In addition undocumented worker make up 25% of the total workforce in farming† (Legalization Has Many Perceived Benefits 2010). â€Å"It has accommodated an expanding labor supply that today includes 1.5 million immigrants per year whose spending on housing and consumer goods helps stimulate the economy and increase the demand for still more labor† (Immigration: impact on U.S. economy 2010). However, in true fairness to the immigrants, it should be said that they are contributing a lot to the economic development and progress of this nation, in all major areas of business, commerce and trade. â€Å"Illegal immigration into the United States is a highly profitable proposition for both employers and the U.S. government, and it also benefits Mexico, which

Information systems technology change What Bert Painter does and does Essay

Information systems technology change What Bert Painter does and does not tell us - Essay Example The purpose of this paper is to distill the primary lessons regarding IT systems change that Painter is trying to convey in his paper, determine how one would evaluate those lessons in terms of their correctness and usability, and to discuss any other lessons not part of his conclusions that have been learned by the writer and which he holds the hope of putting into practice in his or her future IT career. In other words, the purpose is to discuss what Bert Painter does and does not tell us regarding information systems technology change. Painter discusses his experience aiding an insurance company's paper-based system into one that was electronic and was known as E-File. The new process allowed the company to integrate their data and automate their workflow, as well as significantly redesign jobs to be more efficient in the overall process. Painter directly states what he hoped to achieve through sharing the results of this case study (Painter, 2008). According to Painter in the case study, "A socio-technical approach to organization design can mitigate potentially negative effects of information technology, while maximizing positive potentials to up-skill jobs, and yield an outcome, such as with E-File, where over 90% of the highly skilled employees surveyed in this white-collar organization regard the new system as a substantially positive change" (Painter, 2008, pg. 1). Throughout his consultation process, Painter relied on surveys that had been developed in key areas. These included effects on work processes, effects on job aspects, the user-friendliness of software and hardware, and competence and knowledge. He likely shared details of these sections as he felt they were very important aspects of socio-technical design. In fact, he probably thought that the information gathered through this information carried the primary lessons that he wished to convey to his audience (Painter, 2008). Evaluating the Lessons and Looking at Other Lessons As far as evaluating the lessons that were presented in this case study in terms of correctness and usability, they all seem to be quite useful when perhaps broken down and applied to general management concepts that anybody could use. The reason they seemed rather limited in scope in this particular case was likely because this was, after all, a case study and, therefore, it focused on one company's specific application of the lessons at hand (Painter, 2008). The general definitions of socio-technical design that are given in the introduction and the conclusion of this paper contain more generalized concepts, which is what one misses when reading Painter's case study. For example, the direct participation that was given in the case study was in the form of interviews and surveys. It could be given in other ways as well, such as through meetings where everyone in the company is made to feel important. The system of socio-technical design was definitely present in the case study and is likely to be very similar for various different firms that are looking to undergo this process. One serious fault that could occur when designing or implementing this process is to not take into account just how serious the opinions and feedback of the end users are. If a

Use Of Force Managemnt Essay Example | Topics and Well Written Essays - 500 words

Use Of Force Managemnt - Essay Example The U.S. Department of Justice, through its Community Oriented Policing Services, indicated that the use of force was a natural reaction in response to cases requiring apprehension of suspected criminals to protect one lives and that of others. Likewise, it was indicated in a published report by COPS that there was actually no clear and concise definition of the use of force but the accepted meaning was sourced from â€Å"the  International Association of Chiefs of Police  (IACP) in its study,  Police Use of Force in America 2001, defined use of force as "The amount of effort required by police to compel compliance by an unwilling subject.†" (U.S. DOJ: COPS, 2010). In this regard, the research aims to proffer issues on the use of force, specifically focusing on police brutality by identifying the problem, accountability, enhanced police accountability, accreditation and risk management, among others. A recommendation from the issues discussed would be presented prior to concluding remarks. Due to the critical position, tasks and responsibilities accorded to private security officers, there have been several documented instances of abuse of their authority. As such â€Å"most of these crimes fall into five broad areas: excessive force, sexual assaults, false arrest and fabrication of evidence, deprivation of property, and failure to keep from harm.† (FBI: Color of Law Abuses, 2010, par. 4). When the use of force becomes excessive and unreasonable, police brutality ensues, thereby posing dangers to the victims in terms of violations of human rights and even the possibility of grave injuries and death. According to David Mangan in his written article entitled Police Brutality: The Use of Excessive Force published as a Drury University paper, the use of excessive force tantamount to manifesting a form of police brutality is actually a criminal act constituting

Business Proposal for Als Milk Bar Essay Example | Topics and Well Written Essays - 3000 words

Business Proposal for Als Milk Bar - Essay Example The objective of the business is to provide a unique "milk bar" experience to its customers with high quality food, customer-oriented service in a warm and friendly atmosphere. The target market range covers ages 5 to 75, among the local residents, office workers, students, shoppers and pedestrians in the area of Victoria Street. Projected investment costs of less than $18,000 are deemed recoverable in less than two years with profitability from operations set at 18%. Traditionally, milk bars were local shops where people pick up milk and newspapers. Eventually, they became general stores or delicatessens, offering a wide variety of products, much like convenience stores. They also began serving milk drinks and other non-alcoholic beverages, such as milkshakes and sodas, as well as snack foods like sandwiches, cookies and pastries (Wikipedia 2008). Milk bars became popular starting in the 1930's when they became hubs providing wholesome corner shop goodies and a communal space for local interaction. Customers personally knew the people behind the counter, kids were allowed by their moms to drop by to get candy or have a milkshake, and communal tables allowed neighbors to bump into each other. The milk bars of the period had brightly lettered conspicuous signs advertising hand-made foods such as meat and vegetable rolls, hot pies and pasties, freshly made scones, double cream milk shakes, malt chocolate drink and fruity syrup slush. Dcor in the ea ting areas were a combination of colorful posters and cartoony images of the era (Neville 2008, Bells 2008). The "restaurant" portion of the 1930s milk bar is the inspiration for the new business being proposed. The business concept revolves around the idea of a bar and snack establishment serving non-alcoholic beverages and hot food, where customers can either have a quick drink or snack, as well as linger with friends. Business Description "Al's" Milk Bar is to be located at 314-316 Victoria Street. It is a bar and snack restaurant providing hot and cold food and non-alcoholic drinks reminiscent of the 1930s milk bar experience. Its menu will include all the traditional offerings of milk bars such as milkshakes, spiders, sodas, ice cream, cakes, pastries, sandwiches, hot rolls, as well as mocktails. "Al's" dcor and color schemes will mimic those of the 1930s and 40s milk bars, complete with a bar counter with seating and indoor and outdoor tables and chairs. "Al's" will be a small business established as a sole trader and will operate from seven in the morning to nine in the evening every day of the week. It will serve a high number of residents in the surrounding local residential areas as well as office workers in surrounding office buildings and shoppers at nearby retail venues. It will have product offerings to serve quick breakfast, especially to office workers, light mid-day lunches, and afternoon-evening non-alcoholic dri

Deal Directly With The Issue Of Death Essay Example | Topics and Well Written Essays - 1250 words

Deal Directly With The Issue Of Death - Essay Example Whereas in Seneca’s ‘on shortness of life’, he explains the life is not short as people think if it is used in the right manner. Nature has given enough time to human being to accomplish what they want. He sees natural phenomena as the metaphor for life. So death is a natural process to him, which has to be dealt with courage and willingness. According to him, human spirit should adapt to the natural law of death. He claims that human beings are bad soldiers who do not follow the commands of God. This is very true as it can be seen widely that human beings have always acted opposite to God’s commands and rules. It is natural for beings that are once born to die and accepting it is the wisdom in real man. In the same manner, Socrates also suggests that man should neither fear in life nor in death. From his thinking, we can understand the greatness of him. The first and worst fear of a human being is dead and one who advocates fearlessness to death indeed is a genius. A man who is spiritually educated will never have the concern in dying as he knows it is a hard truth. He will respect and obey the law of nature and enjoy both life and death equally. This is because he knows that soul is immortal and nothing can kill it or destroy it. In the apology, Socrates gives his genuine perspective on death to people. Socrates reveals that souls are immortal and live forever. It is a fact that soul existed along with God and has been given physical form to be tested by him.... In regard to his death penalty, Socrates responded that his physical body can only perish but not his eternal soul. This is the true nature of human soul and death is just a phase in its journey. Socrates claims that feelings arise from knowledge and since he has no knowledge about death he is not afraid of it. He believes that death is a kind of blessing. This is because; death can give opportunity to a person to go to world he has not been before. There he is able to meet his ancestors and can test them and be in touch with them. This is true as nobody have any idea of where we will go after death and it would be a new experience for human beings to die and know the truth. So in such a case, one should look forward to death which is going to be an exciting experience. Seneca believes that the fear of death is the underlying philosophical root of most other human fears. Seneca like Socrates also believed in the immortal nature of soul. In â€Å"shortness of life† Seneca menti ons that one should think about life rather than death and analyze what is important in life. One should find right attitude to time, and to value and allocate time in the right way. This is very right way of seeing life as people should utilize their time in doing good and being good. In 'Consolation to Helvia', Seneca consoles his mother by saying that material comforts are not the end of life. He explains about the relationship of Man with God and position of a person in the universe. It is true that once we understand our relationship with God we would not be afraid of death. One should understand the working of the natural world to eradicate the fear in the mind about death. Also Socrates in his apology mentions that he has no feeling or emotions about death. He explains that it is not

Art is Art Essay Example for Free

Art is Art Essay What is considered art has been a controversial question for many years in history and today. There are various forms and types of art. Because art is very complex and diverse, it is viewed and conceptualized in many different ways. Nancy G. Heller states even though a type of artwork is hard to understand, it’s considered art, and artwork that people don’t understand shouldn’t be disregarded from other types of art. She feels as though people shouldn’t be intimidated by artwork that’s hard to understand and her main goal is to try to help people feel more comfortable around art they don’t understand. Picasso believes that all art needs to be an original in order to be considerably successful. He states that nature and art are completely different things. Picasso explains that art is a lie that allows us to realize the truth. And finally, John Berger speaks about publicity being a form of art, and how it uses art to manipulate people into buying what is publicized. Berger says publicity ads have a way of working because ads focus on the future, which people are attracted to more than the present. Each of these authors have different opinions on how art is viewed and conceived, however they unite from similar points in their views. All art is art, and shouldn’t be dismissed. In â€Å"’Statement to Marius De Zayas,’ 1923,† Picasso states that art has to convince people of its truthfulness. In his article, Picasso defends the art of cubism.—because cubism, like many other types of art, is not understood yet by most people. However, cubism isn’t any different from a type of art someone likes and understands—it shares the same principles or elements as any/ all other types of art. Picasso elaborates on his claims by giving the reader an example of him reading an English book. He says that reading a book doesn’t make sense to him, yet it doesn’t mean that the English language doesn’t exist. He states that no one should be responsible for him not being able to understand what he doesn’t know much about. Picasso believes that an individual shouldn’t say a type of art isn’t art only because they don’t understand it. The individual should, instead, try to understand it, and if he/ she still doesn’t consider it to be an art, the individual should claim to just dislike that specific type of art. Picasso and Heller both agree that art is art and that it shouldn’t be questioned. Nancy G. Heller’s book, â€Å"Why a Painting is Like a Pizza: a Guide to Understanding and Enjoying  Modern Art† starts with the author’s experience making a pizza in Texas. From her experience, she concluded that painting is like a pizza. Just as many people have a variety of taste in pizza that they prefer, when people look at art, they have certain preferences in art as well. Some people usually completely dismiss certain groups of art, saying its not art at all. Heller defends artists who are victims of these cruel remarks by saying, â€Å"anything anyone says is art should be in fact be regarded as art† (Heller 10). All art should not only be regarded as art, but art also is a lie that uncovers the truth. In Heller’s article, one of her examples shows Rosa Bonheur’s painting â€Å"’The Horse Fair’ (1853).† This painting is very realistic like a photograph. On the contrary, the painting is just very convincing. Bonheur’s painting of the galloping horses lie to the viewer, because the horses aren’t actually galloping in front of the viewer. However, it helps the viewer recognize the truth from the artist’s lies. All art lies, which help the viewer, uncover the truth. Nature and art aren’t the same. Only something real can be natural. Picasso agrees with Heller by saying, â€Å"nature and art, being two different things, cannot be the same thing. Through art, we express our conception of what nature is not† (Picasso par. 5). Picasso states that art needs to be an original idea—otherwise it is useless. An artwork being orig inal allows the viewer to notice the truth. He suggests that art isn’t actually what the artwork portrays. â€Å"Art is not truth. Art is a lie that makes us realize the truth† (Picasso par. 3). Although paintings aren’t real, it can symbolize something that is real. In â€Å"Ways of Seeing† by John Berger, the author talks about all art (publicity ads or paintings) must be convincing to the viewer. â€Å"Publicity begins by working on a natural appetite for pleasure. But it cannot offer the real object of pleasure and there is no convincing substituted for pleasure in that pleasure’s own terms. The more convincingly publicity conveys the pleasure of bathing in a warm, distant sea, the more the spectator-buyer will become aware that he is hundreds of miles away from that sea and the more remote the chance of bathing in it will seem to him† (Berger 132). The author gives an example of how publicity ads work by suggesting if a publicity ad was to show the pleasures of bathing in a warm  and distant sea, the viewer (or buyer) will realize that he is many miles away from the sea that the ad is portraying, and the chance of bathing in that sea will seem far to him. If the viewers aren’t convinced from art, whether it’s a publicity ad or a painting, that artwork is not successful. If a viewer thinks that the representation of whatever the ad is trying to sell is intangible, the viewer will be less convinced. John Berger and Picasso share the same beliefs that art should live in the present. Since there is constant exposure of publicity ads, Berger believes that ads live in the present. Publicity ads are located almost anywhere in this world. From magazines and TVs to buses and billboards, ads are everywhere. Publicity ads are not only constantly around a person’s surroundings, but also are always updated and/ or renewed. Although Berger talks about publicity ads living in the moment, they never represent the present time. Picasso similarly states, if a painting is looked at and appreciated by the viewer, it’s alive, living in the present. Picasso’s work has been echoed in his own idea. All of his work â€Å"was made for the present and with the hope that it will always remain in the present† (Picasso par. 11). Picasso gives an example of the Greek and Egyptian art. He proclaims that Greek and Egyptian art is more alive today than it was when the artwork as cre ated. People are intrigued about how the artwork was made back then, and that alone keeps the early Greek and Egyptian artwork alive in the present. All authors have common beliefs on how art should be viewed and conceived. Art is art and it shouldn’t be questioned. If art is hard to understand, it shouldn’t be dismissed as not art†¦ it should categorized as a type of art an individual dislikes. Furthermore, paintings don’t tell the truth; however it is filled with lies that help an individual recognize the truth through the painting being convincing. And lastly, an artwork lives in the present time—even if the artwork was made in the past. Work Cited Berger, John. Ways Of Seeing. London: Penguin Book, 1977. Print. Heller, Nancy G.

Study of Ceramic Perovskites-type Oxides (ABO3)

Study of Ceramic Perovskites-type Oxides (ABO3) 2.0 LITERATURE REVIEW 2.1 Introduction Ceramic perovskites-type oxides (ABO3) have been studied extensively due to the high conductivity and low activation energy. Among of perovskite type-oxide, an investigation of cerate zirconate attracts great attention to the researcher. It is well known as ion conductor and good chemical stability at intermediate temperature. It properties give big impact for development in technological applications like fuel cells, solar cells, batteries, etc. In addition, one advantages of perovskite is low cost as it can be made from common metals and industrial chemicals. According to Abdullah et al (2012), due to their low activation energy for proton conduction, the perovskite structure with proton-conducting electrolyte material important for development of Solid Oxide Fuel Cell (SOFCs) at intermediate temperature. The investigation of proton conductivity in perovskite has started more than two decades ago. Nd doped BaCeO3 and Y doped BaZrO3 indicate good proton conducting properties under humid at elevated temperature (Azad Irvine, 2007). Meanwhile, alkaline earth zirconates has lower proton conductivity but generally, better chemical and mechanical stability corresponding cerates (Abdullah, Hasan, Osman, 2013). SOFCs enable to convert chemical fuels directly into electrical power. The using SOFC used a ceramic electrolyte requires operating at high temperature and it will put this type of SOFC very great demands on the materials and technology lead to significant challenge for further development of the SOCF. Previous report has shown that the high temperature sintering resulted in large particle aggregation and growth and also consumed cost and time. Wet chemical methods (WCMs) used was able to lower the temperature as well as synthesizing time but the impurities that needed to be avoided still exist. Thus, many researchers analyze on the using of chelating agent to hinder the impurities (Abdullah, Hasan, Osman Nordin, 2012). 2.2 Hartree-Fock Hartree-Fock (HF) is the basis of molecular orbital (MO) Theory. HF method is an approximation method for determining the energies and wave functions in quantum mechanics. Unlike Density Functional Theory (DFT), the approximation of HF theory involves only exchange functional. It often gives qualitatively correct result. It can be systematically improved the result by carried out an MP2 or MP4 calculation, for example. HF theory was developed to solve the electronic Schrodinger equation resulted from time-dependent Schrodinger equation after refer to Bohn-Oppenheimer. The energy and many other properties of the particles can be obtained by solving Schrodinger Equation for wavefunction,. The Schrodinger equation describes the wavefunction of a particle: (1) = wavefunction m = mass of particle h = Planck’s constant V = potential field in which the particle is moving In molecular system, is a function of the positions of the electrons and the nuclei within the molecule, which will be designated as and, respectively. 2.2.1 Molecular Hamiltonian The Hamiltonian is made up of kinetic and potential energy. The kinetic energy is a summation ofover all the particles in the molecular and the potential energy component is the Coulomb repulsion between each pair of charged entities. T: (2) (3) (4) whereis the distance between two particles, and ej and ek are the charges on particles j dan k. For an electron, the charge is negative, e while for the nucleus the charge is positive, Ze, where Z is the atomic number for that atom. The full Hamiltonian can be written as: (5) From Born-Oppenheimer approximation which allows two parts of the problem to be solved independently, the kinetic energy for nuclei in Hamiltonian. 2.3 Density Functional Theory Density functional theory (DFT) is a quantum mechanical method that be used in physics field and has become one of the most commonly used techniques in computational chemistry. DFT is a well-known quantum mechanical method to investigate complex many-body problems at the electronics structure level such as charge, bond length, density and energy. Various names for DFT models are named through combination of exchange and correlation functional. DFT has two functional which is traditional functional and hybrid functional. The traditional functionals consist two types correlation components which are correlation functional and gradient-corrected functional. Correlation functionals involve only the values of the electron spin densities while gradient-corrected functionals involve both the values of the electron spin densities and their gradients. For the hybrid functional, it consist the combination of Hartree-Fock exchange and DFT exchange-correlation. For B3LYP, it contains the Becke Three Parameter Hybrid Functionals that using non-local correlation provided by Lee, Yang and Parr functionals, abbreviated as B3LYP. B3LYP exchange-correlation functional is: (6) Where a0 = 0.20, aX = 0.72, and aC = 0.81, while the and are generalized gradient approximation (GGA), is the VWN local density approximation (LDA) to the correlation functional. GGA originally are called nonlocals approximations or semilocal approximations. The gradient of density is usually determined numerically. However, GGA has limited applicapability. It cannot describe rlimit of xc-energy density and the xc-potential simultaneously correctly. Eschrig (1996) said the DFT method was important in providing the interested mathematician with the physicist’s view on the logical roots of the theory and also for those who want to get deeper insight into the meaning of the results of practical calculations. In addition, from previous study, DFT method was able to justify the interaction between ligands and metal fragments in coordination compound (Chermette, 1998). 2.4 Basis Set A basis set defined as the mathematical description of the orbitals within a system used to perform the theoretical calculation. Standard basis sets for electronic structure calculations use linear combinations of Gaussian functions to create the molecular orbitals. There are few types of basis set effects such as minimal basis sets, split valence basis sets, polarized basis sets and diffuse functions basis sets. Minimal basis sets on each atom in the molecules contain minimum number of basis function and they are fixed-size atomic-type orbital. Split valence basis sets can be made larger by increase the number of basis functions of each atom. The orbital is allowed to change the size but not the shape. In contrast with polarized basis sets that allow orbital to change size and shape by adding orbitals with angular momentum beyond what is required for the ground state to the description of each atom. The molecular orbitals are fixed linear combinations from one-electron functions and known as basis functions. They are centered on the nuclei of atom and share some similarity to atomic orbitals. An individual molecular orbital is defined as: (7) The coefficients c µi are known as the molecular orbital expansion coefficients. The further explanation for the above equation can be obtained in â€Å"Exploring Chemistry with Electronic Structure Method† books. 2.6 Metal Ligand Complexes The metal chelate has its own unique properties. The same ligand with different metal chelates share similar properties. The chelating agent complexes with the metal cation, forming a three-dimensional structure that blocks the ion’s normal reactive sites and prevents it from reacting as it normally would (â€Å"Chemical Properties of Chelates,† n.d.). The chelating agents can form coordination compounds with a metal ion as it is usually contain donor atoms like nitrogen and oxygen (Leopold et al., 2008). One of the acti ve investigations of the synthesizing methods for the formation of a single- phase cerate zirconate powder is the lowering of the processing temperature. Using different chelating agent can lower the temperature processing. Different strength of chelating agent gives different interaction during the chelation process(Abdullah et al., 2013). A recent report shows that the temperature can be lowered by combining TETA and Ba2+ cation in forming the ligand-metal complexes solution. The chelating agent of TETA effectively reduces the formation of BaCO3 in final powder (Abdullah et al., 2012).
