Lincoln Vs. Davis Essays - Stateless People, American Civil War

Lincoln Vs. Davis Charles Beard, a noted historian said that the American Civil War was a conflict between industry and agriculture. Alexander Stephens, a southern statesman said that the war was about states rights. Horace Greeley, a northern newspaper man, and prominent abolitionist claimed the war was fought over the issue of slavery. Abraham Lincoln said it was a struggle testing whether that nation, or any nation, so conceived and so dedicated can long endure. Lincoln said his paramount object was to save the Union, and if he could accomplish that by not freeing any slaves, he would free none; if I could save it by freeing all the slaves I would do it; and if I could save it by freeing some and leaving others alone I would also do that. What I do about slavery and the colored race, I do because I believe it helps to save the Union. What would have happened if Davis would have said that his paramount object was to save the Confederacy, and if he could accomplish that by not freeing any slaves, he would free none; if he could save it by freeing all the slaves he would do it; and if he could save it by freeing some and leaving others alone he would also do that. What if he would have taken the attitude that what he did about slavery and the colored race would be done to help save the Confederacy? Jefferson Davis was profoundly dedicated to the cause that he led. Many prominent Southerners, including Robert E. Lee, were troubled in conscience by slavery. Davis never manifested any qualms about either slavery or secession. His support of state sovereignty and the Southern way of life was based on deep conviction. When Lincoln composed the Gettysburg Address he did not talk much about the way most historians perceive the war. It was his perception...The men who had died at Gettysburg, Vicksburg, Chancellorsville, Balls Bluff, Big Bethel, Shiloh...had not given the last full measure of devotion to free the slaves, nor to establish a modern nation nor to create an industrial empire. They died for the Union, and beyond that for the idea of democracy, so that the ray of hope sent forth by the American Revolution would never dim (Stephen E. Ambrose). The issue of the Civil War was democracy. Lincoln saw to it that the North fought to insure that government of the people, by the people, and for the people shall not perish from the earth. The constitution drawn up at Montgomery defined the new government as the creation of sovereign and independent states. Davis subscribed to the principles of state sovereignty but he was far less provincial in his views than were many of his fellow Confederates. As the South's chief executive he was tremendously handicapped by the deep and pervasive attachment of Southerners to states rights(Bell I. Wiley). Davis was also handicapped by the excessive individualism which characterized the South's ruling classes. The individualism was a product of the plantation system. Each planter was in effect a petty sovereign and his exalted status tended to make him self-reliant, proud, resentful of opposition, and averse to teamwork. Great men are never cruel without necessity. In war as in politics, no evil, even if it is permissible under the rules, is excusable unless it is absolutely necessary. Everything beyond that is a crime. Men who have changed the world never achieved their success by winning the chief citizens to their side, but always by stirring the masses. The first method is that of a schemer and leads only to mediocre results; the other method is the path of genius and changes the face of the world (Napoleon Bonaparte). According to his contemporary critics, Abraham Lincoln's Presidential record was notable for his despotic use of power and his blatant disregard for the Constitution. Lincoln ordered thousands of arrests, kept political enemies in prison without bringing charges against them, refused these hapless men their right to trial by a jury of their peers, and ignored orders from the Chief Justice of the Supreme Court to release them. In his first few months in office he made the most direct violations

Michael Jordan Essays - McDonalds High School All-Americans

Michael Jordan Essays - McDonalds High School All-Americans Michael Jordan Michael Jordan was born on January 17, 1963 in Brooklyn, New York and was raised in Wilmington, North Carolina. He has two brothers, is married, and has three kids. He is considered by many to be the greatest basketball player of all time (Kornbluth). My focus will be on his hardships, accomplishments, and people who influenced him. First, I would like to touch on some general information about Michael. He wears number 23 on his jersey because he considered it to be half of his brother's number, 45. He had wanted 45 because it was his brother's number and he deeply admired his brother, but he was on the same team as his brother so he needed to pick a different number. His most well known superstition is that he wears his University of North Carolina basketball shorts under his game shorts. When Michael was a kid, his favorite sport was not basketball. In fact, it was baseball. He was a pitcher on a little league team. He played baseball because he was short (Kornbluth). Later in his life, he would try to leave the NBA and play major league baseball. Michael was not always rich. His parents had to work two and three jobs each to support the family. Before Michael's dad built him a basketball court in his back yard Michael shot, basketballs into a trash can (Kornbluth). Michael was not always good at basketball, either. People told Michael that he was too short to play basketball. Michael now stands six feet six inches tall. He also went to the school gym before school to shoot baskets, stayed after school to shoot baskets, and could be found in the school gym on weekends shooting baskets. He also played his brother, Larry, one-on-one in basketball. His brother was only a year older than Michael was, but he was much better and taller than Michael was. Michael would often times lose and end up getting in a fight with his brother. This caused Michael to be extremely determined to succeed at basketball (Kornbluth). In his sophomore year of high school, he tried out for the Varsity team. He did not make it, so he was placed on the Junior Varsity team. On the J.V. team, he averaged 28 points per game. He thought this would get the attention of the Varsity team coach. It did. However, it was not in the way he hoped it would. The assistant coach for the Varsity team was sick so they needed someone to hand out towels to the players while on a playoff road trip. That is what Michael got to do (Kornbluth). When he finally got on the Varsity team in his junior year, he still worked hard. He practiced with both the Varsity and the Junior Varsity teams and continued to go to the school gym and work on his shooting (Kornbluth). Michael's hard work would attract many scouts from colleges (Kornbluth). He would go to the University of North Carolina at Chapel Hill. In college, he was a very good player. In his junior year, the Tar Heels went to the NCAA Championship game where he would hit a clutch game winning buzzer beater to win the NCAA Championship. In 1984, Michael played for the United States Olympic basketball team. Michael was among the best college players in the country and helped the team win the gold medal. Michael was also part of the 1992 United States Olympic basketball team. The team was composed of the best NBA players and was nicknamed "The Dream Team." This Olympic team also won the gold medal (www.unc.edu/~lbrooks2/jordan.html). Michael was drafted after his junior year in college and would be the third pick in the first round of the 1984 NBA Draft. He went to the Chicago Bulls, who at that time were a struggling team. With Michael on their team, they started to win. Michael was the NBA's rookie of the year in 1985. He would also be a NBA all-star in his rookie year and a NBA all-star game starter in 1987, 1988, 1989, 1990, 1991, 1992, 1993, and 1996. In 1988 Michael would win the first of four league MVP honors, the others being 1991, 1992, and 1996. He was

Gods True Prayer Essay Example | Topics and Well Written Essays - 750 words

Gods True Prayer - Essay Example The prayer also indicates that for this relationship with Jesus to work, the Believers necessarily ought to continue to accept the truth of the message by heart and follow or imitate Christ’s righteousness sincerely. This is a way of truly knowing who belong to the Father and deserve to be with Him in the eternal life after death by the time Judgment comes. 2. What does this prayer tell us about the Believers relationship to the world? Based on this prayer, the Believers do not actually belong to the world forever. Besides being in the world temporarily to come to discover God-endowed human potentials and to appreciate His creation, the world serves as a ground where men are exposed to the physical matter, as opposed to the spiritual so that they may eventually be able to distinguish the divine nature from the human nature and the wonders of faith or forming convictions without having to see in reality Whom one has developed faith with. So in other words, the Earth becomes a p lace of huge significance as it puts each Believer’s faith to test through worldly temptations then filters who among those who initially follow Christ would be his disciple until the end. The world is a representation of what humans are prior to knowledge of God by faith. It signifies weakness of human nature or that which usually cuts the fellowship of Believers in God’s community. If one is ‘of the world’ and could not leave his material possessions behind in exchange of entering God’s kingdom, it is then impossible to be with God since His nature is divine or spiritual and is not in any way made of anything out of the world. 3. What does this prayer tell us about the Believers relationship to the Father? As he utters ‘I have made you known to them, and will continue to make you known in order that the love you have for me may be in them and that I myself may be in them’ (John 17:26), Jesus similarly desires for the Bible readers to understand that the Believers belong to the Father as His children. Thus, he is given the essential mission of making Him known to the world so that the world may know that He is the Father in return. God expresses His unconditional love toward the Believers, being their Creator and Father who possesses immeasurable abundance in power, mercy, grace, and wisdom which He has constantly imparted mankind to this point due to His unfailing love despite man’s shortfall. Through ‘The High Priestly Prayer of Christ’, Jesus addresses the essence of establishing a relationship with God through Christ that goes beyond mere church traditions. The substance of the prayer calls for righteousness other than fulfilling religious obligations or that to a deeper extent, the Believers are anticipated to genuinely love God back for it is His desire as well for the world to comprehend that He is not a distant being or entity who only punishes the ‘evil’ and rewards the à ¢â‚¬Ëœgood’. Rather, due to the full measure of His love, He does not keep records of wrongs regardless of the number of times sins are committed thus, with an overflowing grace and compassion, He is the Father who is ready to forgive or redeem an unrighteous

Chemical enginering assignment - Essay Example The acetic acid which is the vapour is then cooled to obtain its distillate. From the cooler the acetic acid stream containing paracetamol and water (product) enters evaporator for concentration (increasing its concentration) by removal of certain portions of water from the product. Consider the flow diagram below; According to mass balance principle, mass of materials entering a system is equal to the mass of materials leaving the system assuming that there are neither losses within the system nor losses associated with the processes under which the materials entering the system undergo (Wacharawichanant 2012). This can be expressed mathematically as shown below, As of the case of processing paracetamol, the rate of mass of products (paracetamol) entering the evaporator is equal to rate of mass of mass of concentrate leaving the system plus rate of mass of vapour leaving the system. Mass balance can be expressed mathematically as shown below, (consider Figure 1) The mass of the products from cooler, (the mass of Acetic acid + Water + paracetamol) was 2319 Kg per hour (Kg/hr) (From L-37) of the Engineering line diagram (report 2). After evaporation the mass of the concentrate obtained per hour was 1380.85 Kg per hour. Therefore, the mass of the vapour (acetic acid vapur) assuming that no loss occurred as a result of evaporation process can be calculated as follows. In order that required quantity of paracetamol per year is obtained, and assuming other factors are constant, the product from the cooler should be fed at rate of 2319 Kilograms per hour or 55656 Kilograms per day (assuming that the plant will work 24 hours per day). A measure of concentration process that takes place in the evaporator is what is known as evaporation ratio, and it is calculated as shown above. When concentrating the solution F (dilute paracetamol) at a steady rate, the concentration rate starts

The Importance Of Record Management

The Importance Of Record Management A record is a transaction between individuals or institutions that is first documented and then stored on a specific repository for a given, or in some cases an unspecified amount of time. Records vary in their contexts they can range from court records to state information that a country holds about its citizens i.e. birth and death certificates. Records in the current day and age are usually stored electronically on databases. Records provide an organization or government institutions with the necessary proof of the interaction with its partners, in the case of organizations, or citizens in the case of the state. Why is records management important and who is responsible for managing records in an organization? Records management is important because it essentially provides an organization or any other entity with of proof of the transaction that they have entered into with another party. It is also important in the decision making or strategic part of an organization. Kept records prevent data anomalies or inconsistencies, this is key on the part of those making decision for the company, if a department within an organization has managed to keep good track of what they have done or have not done it becomes easier for them to make decisions based on those records. Everybody in the organization is partially responsible for managing records in the organization. Employees have a responsibility to make sure that all their transactions with external parties related to the organization are kept recorded and stored electronically. However, the records manager or information officer is tasked with managing the records for the whole organization together with his/her team. The records manager is also responsible for drawing up policies that articulate the aims of his/her department to the rest of the organization. This is to make sure that everyone within the organization knows how to handle information and is also knowledgeable on the legal and corporate standards associated with records management. Outline an electronic records management cycle. I have identified four phases to the records management life cycle, with the understanding that there possibly could be more that can be identified or less. The first being: Creation. This entails the part of the cycle when records are being created or being received. The second part is: Active Records: these are records that are needed frequently. They are retrieved at least one per or month or as frequently as weekly, so these types of records are stored on readily accessible databases. The third part is: Semi-Active/Inactive Records: Semi active records are not needed for day-to-day business. Organizations need to keep them for referrals for legal reasons, of for financial reasons. They are not used often enough to warrant or justify their being stored in primary record centres. Semi-active records are often stored at a lower cost in a records centre. The fourth part being: Final disposition: The final disposition is the action that takes place when records have no more value to an organization. This phase can include physical destruction of the records of transfer of the records to the custody of an external body. What do you see as user interactions with the records? The user of the records is in the first place a part of the creation process of a particular record. Their input to the process is the relationship they have with the organization. The degree to which they interact with the records depends on the context and meaning of the relationship to an organization. Users of course could range from customers to employees. Employeesà ¢Ã¢â€š ¬Ã¢â€ž ¢ interaction with record should include them maintaining the records that they have created and updating them if necessary. A customer to an organization interacts with his/her record when they need to consult the business about the transaction they had with that particular business. What is an ERDMS and what are the benefits you see ERDMS bringing to your organization? An ERDMS is an Electronic Records and Documents Management System that is used for managing and storing records digitally. It is used to effectively manage paper and electronic records and documents. The benefits of such a system can in oneà ¢Ã¢â€š ¬Ã¢â€ž ¢s view be separated from individual to organization. For the individual it can mean a quicker and more convenient discovery and access to information. An improved administrative efficiency and effectiveness. It could also mean the facilitation of evidence based information decision making. For the organization it could translate into secure and systematic management of unstructured data such as emails, documents and spreadsheets. And also efficiency gains with improved quality and consistency of organizational processes. Another benefit that one sees for the organization making use of this system is that there can be an enhancement of a recordkeeping culture in other words this best practice can be institutionalized to the whole of the organization. There can also be a reduction in records lost, and reduction in legal liability to exposure. An ability to integrate core business applications with core business applications with the ERDMS can enable improved records capture through automation. List the ERDMS functionalities and briefly describe each functionality indicating its importance? Functionality (a): What is stored? On these systems electronic files such as word processing documents, spreadsheets, multimedia materials etc are stored. Functionality (b): What end users can do? End users can create new documents which may or may not be records. They can also save files with limited metadata related to business functions. Functionality (c): Access and use Users can retrieve stored files. They can also receive action files accordance with workflow processes and also edit files and select whether to save as a new version or ne w document Functionality (d): Disposal. The users of the files can delete them when they do not serve any corporate or legal purpose their department or the whole organization.

Applying Leadership Theories Essay

According to Wikipedia, leadership has been described as â€Å"a process of social influence or persuasion by which one person can enlist the aid and support of others in the accomplishment of a common task†. Studies of leadership have produced theories involving traits, situational interaction, function, behavior, power, vision, values, charisma, and intelligence, among others. (http://en.wikipedia.org/wiki/Leadership). There are various leadership theories that have been created that encompass how a leader relates to others within and outside of the educational organization. There a six that were specifically proposed by Martin, Wright, and Danzig (2003) that are appropriate when describing educational leaders. They are Directive, Participative, Collaborative, Coaching, Affiliative, and Laissez-Faire. A leader can possess all of these styles depending on the current situation. For example, a leader can use a Directive Approach when dealing with low assessment scores especially when being pressured from his or her superiors, when deadlines are not being met, or when a teacher or staff has neglected their duties. But also display a Participative or Collaborative style by taking input from others. The leadership style that is displayed can have a negative and positive influence on the school community and the organization. It is very important to understand the styles indivially and in detail to know which ones are more and less effective in your environment. The school where I currently work just received a new principal, but prior to her there was Principal R, who had inherited her position as the leader because her entire career was built at the school. She started off her teaching career there, three years later was advanced to Reading Coach, and then was assigned as Vice Principal. The Superintendent, formal principal, and others felt that she was the best fit for the job because of her years spent there and her experience as Vice Principal. Prior to her receiving the role of prinicpal, we were excelling in reading, writing, and mathematics. The principal prior to Principal R had moved us from a failing grade of an â€Å"F† to an excelling grade of an â€Å"A†. Principal R indeed knew the ends and outs of the school because she was trained and mentored by our previous principal, Principal P. Not knowing that once the school was completely turned over to Principal R, we will be on a descending trip to failure. Principal R took a Directive approach, very similar to the Autocratic Leadership Style. By her having experience, she insisted on doing it all herself even though she had an administration team which consisted of a vice principal, reading and math coach, and an ESE liaison. She felt that the ultimate decision in any situation should be hers regardless of whom or what it affected. Research states, that Autocratic Leaders often maintain authority by force, intimidations, threats, rewards, punishment, or position (http://ctb.ku.edu/en/tablecontents/sub_section_main_1122.aspx). If you challenged Principal R in any way, regardless of how simple or how large the issue may have been your evaluation would be affected. Principal R used this role for her own personal gains. Principal R had built many personal relationships prior to her taking on the leadership role, those relationships were soon affected when she became principal. Favoritism became a common word around the school. Things that we thought we would never get away with, was done often by the people in Principal R’s circle. This leadership style brought a negative image to the school. The morale went down and teacher’s lost their drive for teaching. Our school grade went from an â€Å"A† to a â€Å"C†, then to a â€Å"B† to an â€Å"F†. Principal R was transferred to another school where we hope her style would change for the benefit of the vision of the school. While under the leader of Principal R, we also had Vice Principal E, who was a very sweet person with more than 16 years of experience in the education field. Our school was labeled for having struggling readers which put more accountability upon the teachers. Regardless of what issues the st udents had years prior or even home structure that affected their abilities to read, we were held accountable for them if they were below average or even failing. Vice Principal E shared many strategies with us that were very beneficial to our students. Her education specialty was ESE and autism; we were able to use those same strategies to assist our students. Vice Principal E displayed a Coaching Leadership style also very similar to an Instructional Leadership style. Her main concern was teaching and learning and assist us in relaying information in a way that the students comprehended. Instructional leadership focuses on modeling, monitoring, professional dialogue and discussion (Bush, 2002). She mentored us on what routes we should use to assist our students. She increased our confidence and also our test scores. When the results came in and we seen how much gains our grade level had shown, Vice Principal E took no credit, even though it was all because of her. She remained in the mentor role and assisted us in anything we may have needed. Vice Principal E was surplused to another school due to budget issues and was missed dearly when she departed. We are currently under the leadership of Principal K, which is the true reason why I am pursing my master’s degree. Principal K is a new principal, but has 12 years experience as a vice principal in secondary education. Principal K is a true leader that models and motivates others to accomplish goals, while at the same time encouraging others to work toward their own professional goals. Principal K, came ready to work but with little knowledge of what direction to start. Principal K created groups of those teachers and staff, whom prior had experience at the school to assist her with understanding the vision and desegregating the data. Once Principal K understood the vision and the direction of where the school should be headed, she quickly took the Collaborative approach, also known as the Democratic Leadership style. She involved the faculty, staff, and stakeholders in the decision making process. Even though the final decision would be ultimately made by Principal K, she allowed everyone to be a part of the process. She allowed them to have the sense of belonging of being a part of the team. She encourages participation, values our opinions, group discussions, and motivates us to become leaders as well. Principal K’s leadership style provides direction and guidance. She states often that even though her title is principal her job description is to work for us and whatever we need to give the students a quality education, she will make sure it is provided. Overall, leadership styles is the manner and approach of providing direction, creating visions, implementing and acting on plans, and motivating people to excel beyond their comfort zone. Leaders styles will vary based on situations. A leader does not strictly lean toward one style, however one may seem to be dominate over another, but it all depends on the situation at hand. My goal is to use the styles that are most effective and meant to strengthen the performance of the teacher, staff and students and also the styles that will bring improvement on student achievement.
