Development of a Mathematical Model - Essay Example Major immediate concerns are the possibility of underground movement of the gasoline, pollution of ground water and sewage systems and contamination of housing by toxic and flammable fumes. The effects of this spillage is mainly on water pollution and air pollution, the sewage pollution is not likely to have any effect on the people, the pollution of underground water as a result of this spillage and air pollution due to the effects of flammable flames are likely to affect the people and therefore we will develop a mathematical model as follows that explains this effects. Petroleum products are hydrocarbons and have the chemical formula CnH2n+2; Trimethylpentane is used as gasoline and has the chemical formula C8H18, in this scenario therefore the contact of petroleum with oxygen takes the following reaction: This reaction with oxygen produces carbon dioxide, water and heat; however the incomplete combustion of gasoline is harmful in that it causes the formation of carbon monoxide, and nitric oxide as shown below in the chemical reaction: Therefore this will result to the formation of gases that once they are inhaled endanger health, carbon monoxide reacts with red blood cells which carry oxygen from the lungs to the other pats of the body to form an irreversible compound therefore a person who inhales this gas could die due to insufficient oxygen in the body. Petroleum is insoluble in water and therefore does not react with water, it is less dense than water and therefore will float in water, therefore to its causes to underground water will only affect the availability of clean underground water. We will not consider the effect on land because there are no major direct effects as a result of the spillage, we shall not also consider the effect of the spillage on sewage lines because the contents are not of use to human beings. Our major concern therefore is the production of carbon monoxide and nitric oxide, we can form the following mathematical model that analysis the effect of one litre of fuel: One mole of gas occupies 26.5 litres volume at standard temperature and pressure, therefore one mole of C8H18 will produce 2 moles of carbon monoxide and two moles of nitric oxide, therefore if 1,000 litres of petroleum was spilt then this will produce 37.74 litres of carbon monoxide and 37.74 moles of nitric oxide.3 The model can therefore be specified as follows E= 2 litres carbon monoxide + two litres nitric oxide, and this is per litre of petroleum spilt, Where E is the total effect. Scenario two (b) There has been a spillage of gasoline from a road tanker in a town (population, 5500). Most of the gasoline

American Idol Essay -- Cheathouse Essays

American Idol â€Å"That rendition was impressive, but you do not look like an American Idol; however, we will give you one more chance. Welcome to Hollywood!† A person with a mediocre voice that is not stunningly attractive would have a harder time advancing to Hollywood on American Idol. As the judges say, an American Idol should be a distinct person with an exceptionally fantastic voice. Culture is the training or refining of intellectual faculties and the way of life for a particular people. My goal will be to critique the ideal of image on American Idol and discuss how people may or may not get though based on looks alone. In the entertainment industry, images of the â€Å"perfect† people are portrayed as women being skinny, tan, and firm and men being handsome, muscular, and original. Judges Randy, Paula, and Simon critique contestants on American Idol mostly based on their image. Randy Jackson, Paula Abdul, and best-known Simon Cowell are the main judges on American Idol. They critique auditions in seven different cities where each performer sings and if well enough, receives the yellow ticket to Hollywood. However, â€Å"This show is called American Idol. It wasn’t good enough† is what many contestants hear. From the millions of people who try out, only a small percentage get though to the second round. The judges place those contestants into groups of three to perform on stage in front of a large audience. They eliminate hundreds of contestants to narrow the field down to jus...

Barack Obama and his Political Propaganda Essay

The process of running for the United States presidency is no easy task. Like in almost any relationship, attraction is the key to provide the foundation for anticipation and expectations. In the beginning, one will always place his best foot forward, and contemplating on addressing issues which would appeal dramatically to other people. Running for the presidency is no less than different with pursuing a girl to have a relationship with you. It all starts with making her pay attention to what you have to say and to what you can offer despite many competitors.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Barack Obama came across the attraction stage with flying colors because he seemed to have captured the attention of most population in the American community, across varying groups and minorities (Martin, 2008, p.1). For one, he appeared to come prepared for what is known as a great battle to get Democratic nomination against Senator Hillary Clinton who is one tough competitor. Obama lacks the experience, and can be said as less popular than Clinton who has established her prominence during the presidency of her husband. However, the appeal in Obama’s candidacy defers the idea that he was only elected as Senator in 2005, and a very young player in the realm of politics.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   This paper aims to explore the political propaganda used by Obama to ensure his future in the White House. For the purpose of the paper, we shall examine the different types of media used by Obama to gain votes and preferences, the manner by which he delivers his agendas, his target audience and supporters, and how this greatly affects his stance in the race to get the democratic nomination. It is certain that the race between Obama and Clinton’s nomination is very tight, but we shall take the time to assess how Obama’s political propaganda has delivered expected results in his leads on major polls and surveys worldwide as Democrats most preferred candidate. â€Å"Change we can believe in† It is a fact that most Americans are demanding change from future politicians in running the country. Many circumstances and events has led Americans hopeful for change and has been the pivotal driving force behind many political agendas. Obama is no exception. By using the ideology of â€Å"change† as a campaign slogan, he ignites the hope among idealistic men and women around the country to believe in what he regards as change (Obama 2008: Change we Believe In, 2008). Obama has a great advantage in speaking with eloquence and sensitivity, with emotions that has words fulfilled with hope and change, gives many people the self-identity they want to see change in the future administration, or in this case, in a democratic candidate for the presidency. This is a note worthy to be taken beforehand, so as to provide a basis on how we can assess Obama’s political propaganda.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Even before the decisive voting held on February 5, 2008, there has been a pronounced shift in favor for Obama of Illinois from opinion polls, surveys, campaign contributions and political and media endorsements (Martin, 2008, p.1). Obama, being a new player in the realm of politics used significant intervention from different political representatives to endorse his candidacy. For example, when Senator Edward Kennedy expressed his fervent support for Obama, it has generated significant contribution in uplifting Obama’s candidacy. As many critics saw it, Kennedy’s endorsement has become a signal of the Democratic Party’s consensus on his candidacy. Following this influential event led to many mass media endorsements of the event including newspapers published in California, Los Angeles Times and La Opinion, which the most widely-read Spanish-language daily.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   After Kennedy’s endorsement, opinion polls showed Obama in strict ties with Senator Clinton for the democratic nomination (Associated Press, 2008). The strategy used governs many political advisers view to gain majority of delegates from key states to secure victory, and Obama did it with just one major political and highly-publicized endorsement.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The appeal of Obama’s political propaganda can be deemed into two significant standpoints. First, the on-going deep desire for social and political change is strongly used by the Obama campaign to hub an illusion, and to foster great support from the idealist (martin, 2008, p. 1). This s highlighted by the mass media by emphasizing that this change will come from someone from the African American community, a fundamentally groundbreaking event in American history if and when Obama wins as the first black President. However, Obama is not a clear product of any acts against racial oppression and civil rights struggles. He is a politician groomed to be of appeal to massive voters in the coming elections.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Obama’s political propaganda seeks to disengage and disassociate itself from the struggle of the elite and ruling class in running the country. More so, the critiques on Obama has seemingly less impacts because of a well-organized activities from the media who supports his candidacy and owes their respective professions to corporate bosses and financial institutions which have their own candidate as preferences. Even Obama’s appeal has penetrated the right-wing group with endorsements from Rupert Murdoch for example.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Also significant of the character of Obama’s political propaganda is the shift in campaign contributions from major business firms. More money means more capability in a candidate’s political machinery. Obama has been endorsed by different military institutions, then national security adviser to President Jimmy Carter, Zbigniew Brzezinski, and Warren Buffett, the second richest man in the United States. Other known mass media executives and corporate executives have also pledged significant amounts for Obama to continue his aspiration on the America presidency. Through continuous efforts from the Obama campaign wagon to instill their dedication towards real change, the Los Angeles Times broke their tradition of not endorsing any candidate with the promotion of Obama’s candidacy in their editorial (Martin, 2008, p.1 ).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     As an observation, although generally the political propaganda of Obama is sufficient for him to gather and maintain support, it is also clear with biases to achieve voters support. For one, it sometimes resorts to Ad Hominem or the attack to his primary opposition and her arguments. In many cases, through debates and news reports, Obama responds to what Clinton offers on a negative tone. Although at times he emphasized their differences, he also had made several points of their similarities obvious to other people. By using change as a promotional concept and advocacy of his candidacy, he often appeals to authority which uses an ideal which is popular amongst people and grant their support for the ideology he used. He also often uses the appeal to prejudice on many public conventions and speaking engagements to evoke the sense of emotional value and goodness to benefit his character. Conclusion The Obama campaign has utilized effective marketing campaign strategies which efficiently used their connections and endorsements form media outlets and institutions. For the most part, Obama is following a political propaganda which is embedded to deny political differences and social classes but with emphasis on the economic differences between individuals in the society.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The Obama political propaganda strongly used news reports, radio, television and posters. It specifically and strategically used these media to indoctrinate various groups of audiences he wished to communicate with and to. Usually through this media, Obama used a directional method on how people can learn about more of his strategies, goals and principles. Through these methods, he intends to initiate individuals as information seekers, to recipients, to reinforcement and opinion leader in favor of his own.

Quantitative research Essay

Isaac and Michael described quantitative research as allowing the researcher to formulate research questions or hypotheses and then to test each under controlled conditions. They decided its greatest merit is the convincing nature of hard data collected that can speak for itself (1974, 354-355). PROCEDURES To conduct this study, the following actions will be taken regarding each of the objectives: First objective: To identify and report the desired behaviors required for future Christian education leaders. 1. The literature of the field will be reviewed in the following areas: (a) Biblical context, (b) Church History, and (c) contemporary ministry. 2. The findings of the literature will be reported in chapter 2. Second objective: To validate the behaviors identified in the literature review. In order for the inventory of behaviors to be comprehensive, Flanagan stated that it is necessary to obtain a sufficiently representative sample (1949, 343). a) The degree of mutuality existing among the behaviors reported will be identified with respect to the different clusters. b) The number of behaviors will continue to be reduced by combining similar behaviors and writing new descriptions without regard for specific categories. c) The final inventory of administrative behaviors will be produced by the researcher. 2. The findings of the inventory of behaviors will be reported in chapter 3. Third objective: To make appropriate recommendations on the selection and training of future education administrators. 1. The study, including the findings of objectives 1 and 2 will be reviewed and summarized. 2. Appropriate conclusions will be drawn. 3. Specific recommendation which emerge from the study will be made, including suggestions for utilization of the competency areas recommended by the study, and suggestions for further research. 4. The summary, conclusions, and recommendation including check list will be reported in chapter 4. ORGANIZATION OF THE STUDY The study will be organized into four chapters in accordance with the Action Research, as table 1 displays. TABLE 1 Organization of the study based on action research Action Research Steps Chapters 1 2 3 4 Planning/Conceptualization X Fact Finding X X X Evaluation X Chapter 1 has stated the problem and purpose, explained the importance of the study, and stated the method. Chapter 2 will survey the literature to identify and report behaviors required to effectively analyze the characteristics of the church leaders, church members and surrounding neighborhood. Chapter 3 will report the validated behaviors for the role of the church. Chapter 4 will review and summarized the study, offer appropriate conclusion and discuss recommendations for change and future study. CHAPTER 2 CHARACTERISTICS We expect every church planter either black or white to be a good leader. Everyone else who knows about leader and his ministry, even including his group people expect it too. This is truly right no matter who a church planter is, may be any man or woman, may be a minister having both in church and outside of the church jobs. He may be a permanent pastor. Every church planter must enquire about his personality by self-questioning in such a personal way so that obtaining answers can help him to be sure about his decision and can help him to find out his true calling these answer can also help planter to know his future as a leader of his group. Our own understanding taught us about good leaders and leadership which we learned by working with different leaders. These leaders are the ones that people have known, read or watched about them. A successful leader has four elements including organization second program third morale and forth leadership. The greatest of four is leadership. Although morale is condition of mind and character that shows the person is brave. It also includes ability to do things with full trust on your self. The organizational element is based on morale followers; program of a church goes where the leadership goes. People have studied different kinds of leaders in secular history and in the Bible. The Lord Jesus Christ is their example as a true leader in Christian service. In the Bible God chose many people as leaders in His work for example Abraham, Noah, Nehemiah, Joseph, Paul and Daniel. Whenever the God leads anyone to think, about going into the Christian ministry he must look for a person who could demonstrate Him, what His person really used to be. A question also rises of what does God require of that person as His leader? And what it takes to be a good leader? The needed qualities of a Christian leader or a church planter should be as the Joseph had he even became a picture or copy of Jesus Christ. Joseph’s acts and character were good qualities for a church leader any church leader with these characteristics will definitely have success. â€Å"It is vital that counselors who collaborate with African American congregations understand that titles and the values assigned to them can be very important in the Black church and within many African American families. Counselors who do not use the formal titles of ministers, church leaders, older church members, and members who have earned doctoral degrees run the risk of hampered rapport. † (2005, 147) The God selected some of His people to be prophets, apostles, pastors, missionaries, and teachers, so that His people would be taught to serve and would become strong. This will carry on until we are united on accepting the Son of God by our faith. All the church has realized the need for leadership; they spend a big part of their life with the life of the church. People often think about the job of church leaders without attempting to connect their roles to the nature and purpose of the church. It means that church leaders become functionaries rather than ministers and become organization maintainers rather than church mission leader. But true black church leader as a person is that who uses his gifts to facilitate others in ministry, and then making suggestions and observations for implications to church.
