Compare and Contrast Harrison Bergeron by Kurt Vonnegut,...

Writing short stories is common for most writers but the writer must give a powerful message in as few pages as they can. While comparing and contrasting short stories â€Å"Harrison Bergeron† written by Kurt Vonnegut, and â€Å"A Saucer of Loneliness† written by Theodore Sturgeon, I found that both stories were science fiction and they both offer scenarios to fascinating what if situations. In this case, both stories answer what if questions to situations where the government controls, but they also relay hidden personal meaning. First, the core plots of both stories is different but I found similarities between the two. Harrison Bergeron is a story that’s based in the United States in the year 2081, where the government creates total equality†¦show more content†¦After she was released, the government continued to follow and watch her closely, and the public and people she dated even bothered her about the saucer’s message. Eventually, she hid from the public, and one day she began tossing bottles with messages inside of them into the ocean every day hoping someone would find them and understand her message. A man found them, and he understood the message. It took him two years to study water currents and wind trails to find her, but when he found her, it was almost too late, as she was attempting to drown herself in the sea. Second, as there are only a few characters in both short stories, they are very different characters but left imprints in my mind. First, in â€Å"Harrison Bergeron† there is Harrison Bergeron who is 14 years old, a genius, a strong athlete, and wears the strongest handicaps of all the people such as bifocals to damage his sight, three hundred pound weights hold him down, and the loudest ear radio. Second, there is Harrison’s father, George Bergeron who is also handicapped by the government for being smart and strong. Third, his mother, Hazel Bergeron who doesn’t need any handicaps because they classify her as an average American who lacks smarts, beauty, and brains. Then the TV announcer who has a speech impediment tried to speak for a few moments on an interrupted new cast, but then passes the microphone to a ballerina to read, who people could tell was beautiful, and strong because

Obtaining a Sustainable Society Free Essays

There is a time where people wonder what the world is going to come to. Is there going to be a time where we run out of resources, or will we run out of room and become over populated? It is natural to wonder these types of questions. So we as humans need to come up with a solution on how we can maintain what we have now before it is gone and we have no future to look forward to. We will write a custom essay sample on Obtaining a Sustainable Society or any similar topic only for you Order Now By doing this we can ensure that our children and our children’s children. In order to obtain a population that can be sustained, whether you live in an over populated area or you live in low population where no one wants to have children. There needs to be some kind of order established to control population anywhere. A country such as Italy has low birth rates; in order to bring them back up incentives need to be put in place to insure that people will want to have children. Another country with a problem with low birth rates is Germany. Us as a world need to find some kind of happy medium, where the policies are not to strict for people with lots of children and not as lenient and glorious to those who only have one. There are many ways Italy and Germany can bring up their population, offer more incentives to married couples that want to have more children. You might want to offer cheaper health care. Cheaper or no cost health care would be ideal for just about anyone. It think this could be the best and the worst thing to do. There would have to be strict rules and regulations upon receiving this type of health care. Free or little no cost health care, would need to be monitored for fraud and so some people could not purposely repopulate without concern for over population. Some people may even have children just knowing of all the benefits they will receive. I think that is just wrong. Another way to be able to raise birth rates would be to abolish abortions, nless it was going to be a medically necessary. I know a few people that would use abortion just as birth control and that is wrong. Not only are you killing God’s master piece, but you are disgusting. In my honest opinion, I think that abortion needs to be looked at more carefully in our own country. I think that there should be a medical reason to why someone may or may not need an abortion. There are struggling couples and countries that want to have children, and then you have the people who use it just because they are not ready or may be too young. Another thing to avoid low birth rates in Italy and Germany would be to make sure married couples make time to procreate. I know that sounds vial and a little bit forward but, if couples can’t make time to take care of their personal lives then how can you make a population grow. Sure there is the use of sperm banks and the use of fertility drugs but, nothing compares to good old fashion procreation. Not having time to reproduce can be affected by a decreasing in the economy and in the loss of jobs. I am not sure how the job market is over in Germany or Italy but, here it’s a little on the slow side. In conclusion, there are so many different reasons why a country will have low birth rates. Any one of these reasons can make any city or country crumble. I think that every man and woman should do their part to repopulate. I also think that certain people don’t need to have any more children. Like for instance, a person who has three to four children should not be able to receive assistance for all those children. In a highly populated area, a person should only receive benefits for a certain number of children. For a country with low birth rates, certain incentives should apply to a couple that wants to have more children. How to cite Obtaining a Sustainable Society, Papers

Analysis of the Leader

Analysis of the Leader Leader-member exchange (LMX) theory, just like other leadership theories, focuses on leadership from a leader’s perspective, such as the style and trait approaches, and from a point of view of the subject and the context. However, the LMX theory has taken a step further to explain leadership as an act that mainly focuses on the interactions between a leader and his subjects. This paper will analyze the LMX theory based on its development, how it works, its weaknesses and strengths.Advertising We will write a custom case study sample on Analysis of the Leader-Member Exchange Theory specifically for you for only $16.05 $11/page Learn More Development of LMX Theory The LMX theory was first developed as the vertical linkage (VDL) theory. In the VDL theory, leadership is viewed as vertical linkages that leaders establish between them and their followers. The relationship that exists between leaders and their followers is merely a series of vertical dyads t hat keep the two together. In the VDL theory, two kinds of relationships exist between the leaders and their followers. They include the out-group, which is based on a formal recruitment, and in-group that describes the expanded and negotiated roles that the leaders assign their followers. A follower in an organizational setup that can belong to either the in-group or the out-group and this depends on how well, he or she associates with the leader. The followers, who work well with the leaders, normally have the highest chance of falling in the in-group. The LMX theory was developed by modifying the VDL theory. In the LMX theory, the relationship between the leader and the follower is established in two stages. The first stage, the acquaintance phase, involves the leader coming close to the follower with an aim of enhancing career-development social exchanges, which entail sharing information and resources at work. The second stage, mature partnership, is characterized by leader-mem ber exchanges that are of high quality. In the second stage, the leaders and the followers have at this point assessed their relationship and found out that they can benefit from each other. How LMX Theory Works The LMX theory works based on two principles; the first principle entails leadership description. In leadership description, LMX outlines the way followers in the in-group and out-group operate. The followers in in-group are closer to the leaders and for that reason, are entitled to more benefits at the workplace. The followers in this category, through the guidance of their leaders, are willing and capable of doing more than what is stated in their job description in order to help the company achieve its goals. Unlike the in-group members, the followers in the out-group category do not go beyond what is prescribed in the job contract. The out-group members do not perform any work that falls out of their job description. The leaders give fair treatment to the out-group membe rs as provided for in the formal contract. Since these members do not employ any extra effort in their operations, they are only entitled to benefits that are listed in their formal contract.Advertising Looking for case study on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More The second principle, the leadership prescription, explains the efforts that leaders employ in availing various forms of opportunities to help the followers adapt to their new jobs. The principle encourages the leaders to develop ways that can assist them build trust between them and the followers to avoid the coming up of the in-group and out-group categories. The principle ensures that the entire unit of a particular work is made an in-group affair to bring the leaders closer to their followers. Strengths The LMX theory has made significant contributions in the way people perceive the concepts of leadership. Unlike other theories of leade rship that do not touch on dyadic headship, the LMX theory addresses the dyadic relationship and describes how the relationship influences the leadership process. Secondly, the LMX theory through its description principle outlines the issues of work units by describing the contribution of every category of followers. It is through the LMX theory that leaders can be motivated to develop a good relationship with their followers. The theory warns the leaders to desist from exercising biased leadership and to treat their followers equally. The theory is the only one of its kind given that it describes how the general performance of a workplace is influenced by the relationship that exists between leaders and their subordinates. The theory also explains how communication influences leadership; this is evident in the high-quality exchanges that are described in the theory. Weaknesses Even though the LMX theory has addressed the most important aspects of leadership, it has a number of shor tfalls. The theory does not explain some of the important aspects of leadership, such as decision-making rules and promotions that are also known to affect how an institution is managed. The theory addresses the out-group and the in-group issues, but it does not explain how a follower can shift from one group to the other. In that case, it is difficult to create inequalities using the LMX theory. The LMX theory is seen to operate on a basis that violates some of the basic human values such as fairness. The theory advocates for creation of in-group and out-group options in a workplace. When the subordinates are divided into these options, they are certainly not be treated equally by their leaders. Lastly, the theory does not mention any empirical studies that it uses to reach the conclusions that it makes.

Burger King Beefs Up Global Operations Case Study

Burger King Beefs Up Global Operations - Case Study Example The company today enjoys a larger foreign market than its main MacDonald. Burger King’s core competency lies in the unique method it uses to cook hamburger. Burger King cooks using flame- broiled method, different from grills that fry. This relates to the company’s service delivery options to its customers. It also offers a variety of options to its customers on how they prefer the burgers served to them. Most of Burger Kings restaurants are in the United States. Since the company started in 1954, its menu has extended to include breakfast, chicken, fish, and salad as part of the menu. Whopper sandwich is until today considered the firm’s signature product. Burger King started in 1954 as InstaBurger King. It went public in 2006 and has since then operated autonomously. The company grew to five restaurants by 1959. It was still in Miami, Florida and operated as a private firm. The name changed to Burger King in 1959 when it started domestic franchising. Pillsbury bought it 1967, after which franchising improved considerably. Pillsbury, in 1989, sold the company to the British company Grand Metropolitan. The merging of Grand Metropolitan and Guinness later formed Diageo, in 1997. The company has well-structured advertisement campaign. It uses big campaign companies outsmarting its competitors. The United States is nearly a full-grown market for fast food despite the growth opportunities available. This is particularly for hamburgers. Burger Kings plans to increase its market to international scale (Parasuraman, Grewal, & Krishnan, 2006). The company targets countries with a large population, mainly of young people, high beef demand and consumption. Other factors include capital availability for franchising and a favorable business environment. McDonalds is the main competitor of Burger Kings. International expansion of Burger Kings is, however, higher than McDonald’s. This presents both

Infomatics Essay Example | Topics and Well Written Essays - 750 words

Infomatics - Essay Example Caregiver, educator, and advocacy roles of a nurse identify need for computer competency towards knowledge development. As a caregiver and an educator, a nurse must develop knowledge that can then be conveyed to the audience for intended purposes and computer applications such as online searches from databases and libraries and communication applications aid these. Caregiver role requires greater competence for applications such as evidence-based research and evidence-based practice that the dynamic nursing environment necessitates. Competence into computer-based applications for data collection, analysis, and interpretation are necessary (McGonigle & Mastrian, 2011) and are my areas of weakness. Undergraduate and graduate students are competent in basic computer skills and have positive attitude towards informatics but parity in competencies between the two levels suggests need better skills at the higher levels (Choi & Martins, 2013) that can be inferred to needs at longer experien ce as mine. Nursing informatics competency is also necessary for improving effectiveness of self-care and for developing strategies for better self-care approaches (Knight & Shea, 2014), and this identifies need for improving my competency level. Use of research software for the application is the greatest weakness. Some software use commands for customization of worksheets to accommodate specific data sets, such as creation of headings for data sets. This remains my challenge and without it, input data lack meaning, and may rely on memory for an understanding. Similarly, specific commands or steps for executing in-built commands are necessary for conducting data analysis using statistical software and I lack the required competence. Results from my PATCH assessment identify my ability to realize the needs through learning to use computer and associated applications. My confidence in learning computer use for professional and creativity tasks, and my

Social Insurance Essay Example for Free

Social Insurance Essay Social insurance funded programs include Social Security, Workmen’s compensation, Medicare, and unemployment benefits. Each of these programs is funded by a portion of a person’s check. A certain amount is taken out of each check and put in an â€Å"account† for future use. Some of these programs even include a match payment made by the employer. This is mostly used for Social Security. The benefits from each of these programs are used in the event of a future time of unemployment. The benefits from Social Security are used when a person is old enough to retire. Workmen’s compensation benefits are available to workers that have been hurt upon the job and are no longer able to work for a certain amount of time. Benefits that are available when a person is unemployed are only available if the person is terminated by no fault of their own. I have found that there is one major drawback to social insurance, the growth in our population. With an increase in population and a decrease in the job market, it is harder for people to go back to work when they have been laid off. Our economy at this point is still unstable. With more and more workers joining the workforce each day and our jobs being sent overseas it is easy to see the drawback to social insurance programs. The one drawback for Social Security according to Chambers Wedel (2005) is that if we are to make it to the projected year of 2040, those who are in workforce will be forced to provide a higher amount of money out of their checks. I feel that any drawback related to social insurance funding is based upon the growth in population and the decrease in our economy.

Criticisms of Jane Eyre Essay -- Jane Eyre

Criticisms of Jane Eyre The major criticisms of the novel in question to be the melodrama used by the author and the wickedness of character shown in Jane and Mr. Rochester. While most critics admired the style of writing and truth of character portrayal, they did not admire the improbability of circumstances or the characters portrayed. Elizabeth Rigby (later Lady Eastlake) was probably the harshest critic, calling Jane Eyre â€Å"the personification of an unregenerate and undisciplined spirit.† Rigby strongly believed that, while Jane was portrayed with a great degree of accuracy, she was herself a flawed person. By making a flawed person interesting, Rigby alleged, the author was committing the greatest of wrongs. As to Jane’s character, Rigby’s main criticism was that Jane was unchristian. â€Å"Altogether the auto-biography of Jane Eyre is pre-eminently an anti-Christian composition. There is throughout it a murmuring against the comforts of the rich and against the privations of the poor, which, as far as each individual is concerned, is a murmuring against God's appointment—there is a proud and perpetual assertion of the rights of man, for which we find no authority either in God's word or in God's providence—there is that pervading tone of ungodly discontent which is at once the most prominent and most subtle evil which the law and the pulpit, which all civilized society in fact has at the present day to contend with. We do not hesitate to say that the tone of mind and thought which has overthrown authority and violated every code human and divine abroad, and fostered Chartism and rebellion at home, is the same which has also written Jane Eyre.† She expressed the popular sentiment of the time that Jane’s di... ... of Jane Eyre supporters.

Baroque Music: Speech And Debate

Speech and Debate 8. October 2009 Baroque Music Hello, my name is and thank you for listening to my speech. Have you ever thought about how music got to the way it is today? Baroque music may seem boring or useless, but is a very important part of music history. Today I am going to talk about the basics of baroque music, the main instruments used during the baroque period, and the influences on baroque composers. So, to give you some background of baroque music, here are the six eras of music. As you can see, baroque is towards the middle, from 1600-1750. Baroque music is easily recognizable from different eras of music because of its distinct qualities. According to essentialsofmusic. com, the baroque era produced very dramatic music. In a baroque piece, there are many switches in dynamics, which means that the music would be soft then all of a sudden loud, or vice versa. This is because the instruments at the time weren’t capable of medium volume. There are also many switches between solos and ensembles, so there would be one person playing, then suddenly the whole group would join. According to baroque. com, baroque music was also very repetitive. The same rhythms were repeated multiple times throughout the piece. Also, the mood was kept the same throughout the piece. For example, when a song began sadly, it ended sadly. The instruments used in a piece of music have a lot of impact on the sound. There were many different types of instruments used during the baroque era. According to thinkquest. com, there were about thirteen main instruments used. The first three, the clavichord, harpsichord, and organ are keyboard-like instruments. The harpsichord is the most popular out of the three and is a factor that makes baroque music unique. The three main string instruments used were the violin, double bass, and lute. The violin was the most popular in the Baroque period whereas the lute and double bass were used more in the Renaissance. The three main wind instruments used were the bassoon, oboe, and flute. The trumpet, trombone, and horn were used in larger groups but not for solos. The only percussion, or drums, used was the timpani, which is a set of five drums that can be tuned to different notes. When a composer is writing music, they are influenced by the things going on around them in the world. During the baroque period, there were many major events occurring. According to Catherine Schmidt-Jones’ article â€Å"Music of the Baroque Period† on cnx. org, the Age of Reason was going on during the baroque period. This meant that many brilliant scientists like Galileo ad Henry Bacon were making discoveries. Also during the Age of Reason, churches had less power than they did in the Middle Ages or Renaissance. So, musicians didn’t rely on them as much to buy their music which led to more diverse and creative styles. According to eh. net, the Age of Crisis was also occurring during the baroque period. This consisted of a very long recession and a war between France, England, and several other small countries, which controlled two of Europe’s biggest economies. Now that you know more about baroque music, here are a few composers from this time. Bach is the one that will be familiar to most of you. Now I am going to play a selection of Baroque music. At the very beginning, you can hear the string instruments, mostly violin, playing very softly. If you listen closely you will hear the counterpoint as many different parts are played at the same time. Then, suddenly the music gets very loud and forceful but still keeps the same mood. The brass instruments are playing in the background but are not the main part. This song is called â€Å"Water Music† and is by George Frideric Handel. In closing, I hope that you can see that baroque music is an important part of musical history. The basics of baroque music, instruments used during the baroque period, and influences on baroque composers are all an important part of what makes up baroque music. So, the next time you hear some older music, instead of tuning it out, listen for the different parts of the piece. Thank you again for listening and I hope you enjoyed my speech.

Caledonia Products Essay

There are a lot of factors that Caledonia must consider when they are thinking about buying versus leasing a property. Leasing brings many positive savings in a company; there are many incidentals that may come up while owning a property, such as the unexpected repairs. Leasing can help with long term savings for a company; it provides the comfort of trying new areas out. If Caledonia starts to branch out, opens up new locations in different states, leasing the building will be a lot smarter of an idea than it would be to buy. Not knowing how well the company will do in that state, will provide tons of savings if things do not go as planned. Along with saving during the long term, Caledonia will be saving in overall taxes. However, if Caledonia has owned a previous leasing site and business is moving. It will be smart for them to go ahead and buy some property. They will be able to save in the long run with owning instead of leasing, because this location will be considered a long term. While owning the site, doing renovations to the building will never be an issue. You will not have to go through the hassle of a third party to the store/ property up to standards to the market. There is already a process with getting permits pulled and getting construction sites up to code. Depending on the overall move that Caledonia wants to go in will have to be based off of their initial plan on getting more property. As mentioned there are many different pro’s and con’s on why either leasing or buying can be considered an option.

Operation Pastorius - World War II German Operation Pastorius

Operation Pastorius - World War II German Operation Pastorius Operation Pastorius Background: With the American entry into World War II in late 1941, German authorities began planning to land agents in the United States to collect intelligence and carry out attacks against industrial targets. Organization of these activities was delegated to the Abwehr, Germanys intelligence agency, which was headed by Admiral Wilhelm Canaris. Direct control of the American operations was given to William Kappe, a long-time Nazi who had lived in the United States for twelve years. Canaris named the American effort Operation Pastorius after Francis Pastorius who led the first German settlement in North America. Preparations: Utilizing the records of the Ausland Institute, a group that had facilitated the return of thousands of Germans from America in the years before the war, Kappe selected twelve men with blue-collar backgrounds, including two who were naturalized citizens, to begin training at the Abwehrs sabotage school near Brandenburg. Four men were quickly dropped from the program, while the remaining eight were divided into two teams under the leadership of George John Dasch and Edward Kerling. Commencing training in April 1942, they received their assignments the following month. Dasch was to lead Ernst Burger, Heinrich Heinck, and Richard Quirin in attacking the hydroelectric plants at Niagara Falls, a cryolite plant in Philadelphia, canal locks on the Ohio River, as well as Aluminum Company of America factories in New York, Illinois, and Tennessee. Kerlings team of Hermann Neubauer, Herbert Haupt, and Werner Thiel were designated to strike the water system in New York City, a railroad station in Newark, Horseshoe Bend near Altoona, PA, as well as canal locks at St. Louis and Cincinnati. The teams planned to rendezvous at Cincinnati on July 4, 1942. Operation Pastorius Landings: Issued explosives and American money, the two teams traveled to Brest, France for transport by U-boat to the United States. Embarking aboard U-584, Kerlings team departed on May 25 for Ponte Vedra Beach, FL, while Daschs team sailed for Long Island aboard U-202 the next day. Arriving first, Daschs team landed on the night of June 13. Coming ashore on a beach near Amagansett, NY, they wore German uniforms to avoid being shot as spies if captured during the landing. Reaching the beach, Daschs men began burying their explosives and other supplies. While his men were changing into civilian clothes, a patrolling Coast Guardsman, Seaman John Cullen, approached the party. Advancing to meet him, Dasch lied and told Cullen that his men were stranded fisherman from Southampton. When Dasch refused an offer to spend the night at the nearby Coast Guard Station, Cullen became suspicious. This was reinforced when one of Daschs men shouted something in German. Realizing that his cover was blown, Dasch attempted to bribe Cullen. Knowing he was outnumbered, Cullen took the money and fled back to the station. Alerting his commanding officer and turning in the money, Cullen and other raced back to the beach. While Daschs men had fled, they saw U-202 departing in the fog. A brief search that morning unearthed the German supplies which had been buried in the sand. The Coast Guard informed the FBI about the incident and Director J. Edgar Hoover imposed a news blackout and commenced a massive manhunt. Unfortunately, Daschs men had already reached New York City and easily evaded the FBIs efforts to locate them. On June 16, Kerlings team landed in Florida without incident and began moving to complete their mission. The Mission Betrayed: Reaching New York, Daschs team took rooms in a hotel and purchased additional civilian clothing. At this point Dasch, aware that Burger had spent seventeen months in a concentration camp, called his comrade for a private meeting. At this gathering, Dasch informed Burger that he disliked the Nazis and intended to betray the mission to the FBI. Before doing so, he wanted Burgers support and backing. Burger informed Dasch that he too had planned to sabotage the operation. Having come to an accord, they decided that Dasch would go to Washington while Burger would remain in New York to oversee Heinck and Quirin. Arriving in Washington, Dasch was initially dismissed by several offices as a crackpot. He was finally taken seriously when he dumped $84,000 of the missions money on the desk of Assistant Director D.M. Ladd. Immediately detained, he was interrogated and debriefed for thirteen hours while a team in New York moved to capture the rest of his team. Dasch cooperated with the authorities, but was unable to provide much information regarding the whereabouts of Kerlings team other than stating they were due to meet in Cincinnati on July 4. He was also able to provide the FBI with a list of German contacts in the United States which had been written in invisible ink on a handkerchief issued to him by the Abwehr. Utilizing this information, the FBI was able to track down Kerlings men and took them into custody. With the plot foiled, Dasch expected to receive a pardon but instead was treated the same as the others. As a result, he asked to be jailed with them so they would not know who betrayed the mission. Trial Execution: Fearful that a civilian court would be too lenient, President Franklin D. Roosevelt ordered that the eight would-be saboteurs be tried by a military tribunal, the first held since the assassination of President Abraham Lincoln. Placed before a seven-member commission, the Germans were accused of: Violating the law of warViolating Article 81 of the Articles of War, defining the offense of corresponding with or giving intelligence to the enemyViolating Article 82 of the Articles of War, defining the offense of spyingConspiracy to commit the offenses alleged in the first three charges Though their lawyers, including Lauson Stone and Kenneth Royall, attempted to have the case moved to a civilian court, their efforts were in vain. The trial moved forward in the Department of Justice Building in Washington that July. All eight were found guilty and sentenced to death. For their assistance in foiling the plot, Dasch and Burger had their sentences commuted by Roosevelt and were given 30 years and life in prison respectively. In 1948, President Harry Truman showed both men clemency and had them deported to the American Zone of occupied Germany. The remaining six were electrocuted at the District Jail in Washington on August 8, 1942.

Personal Ethics Essay Example | Topics and Well Written Essays - 1500 words

Personal Ethics - Essay Example It should also be noted that what a society may consider morally upright might not apply to other societies. This means that personal morality may vary from one society to another. In addition, an individual may go against the society ethical norms and embrace different values depending on his or her conscience and judgment (Howard & Korver, 2008). My personal code of ethics is developed from ethical relativism, which points out that what a society believes in will influence the other person either positively or negatively. In this case, individuals in most cases are influenced by society to make choices for themselves, which in the end may assist in shaping their personal ethical values. The developmental theory coming into play is the learning theory. According to this model, learning ethics values and behaviors takes place through the process of reinforcement and association. Human ethics are shaped by ones society and they define how one is going to apply them in real life situat ions. During my childhood, my society used to frown on me when I engaged in dishonest activities and so through positive reinforcement, honesty became one of my ethical values. My society shaped me positively by enabling me to learn virtue ethics (Howard & Kover,2008). The Ethical system that shapes my codes of ethics is the ethics of virtue. Basing on ethical relativism where the society shapes ones behaviors and ethical standards either positively or negatively, my society instilled virtues ethics in me as I value doing what is right basing on values that are upheld by virtue ethics. The main values that ethics of virtue has promoted include integrity, humility, honesty, respect, being responsible, trust, being principled and trust. Most of these virtues are engrained in almost every society and they form the basis of morality in the world. Upholding positive values that are promoted by ethics of virtue enhance positive human interaction, promote fairness and justice, and enabled one to appreciate and respect the society and other people. In addition, virtue is essential in minimizing perceived immoralities such as crime, child prostitution, war and other social evils. As a woman, upholding my virtuous codes of ethics has been instrumental in my positive behaviors especially when dealing with my family members, children and the society in general. As a woman, my caring, gentle and good behaviors can be attributed to the virtues that I uphold and the social norms that I was subjected to by my society (Kowalski,2012). When applying the ethical codes, I have faced a number of dilemmas, some of which threatened the basic tenets of my beliefs and moral behaviors. One of dilemma is how to handle a situation that requires sound judgment such as a criminal case involving murder. This situation requires fairness and justice without pity or mercy but according to my codes of ethics, humility and mercy are some of the major values that dictate my codes of ethics. I alw ays manage this dilemma by applying the value of principle where I make my decision basing on what I feel is right for a given situation without being dictated by other ethical values that the society may have instilled in me. Further, in solving ethical dilemmas, I consider the environment of a given situation before making any judgment. For example, if a problem occurs between family members, I use the value of

Geotechnical - Essay Example A simpler definition of a dam would be that it is a man-made barricade for water that is built across a river or large source/mass of water especially at the far ends so as to contain the water for use in various means. In the older days, this structure was used with people back then applying dynamic remote materials to contain the flow of water across a river and then engage the reserved the intended usage. This practice of building dams has been carried along historical lines and is still being practiced in the modern world by current generation. However, it is expected that the uses of dams may have been improved and made to be quite sophisticated due to the advancement in technology and techniques of setting up such structures. Currently, dams have been put to use in areas such as the generation of electric power, controlling of floods, supply water for commercial and domestic use, and in navigation among other uses. Subsequently, there are various dams that have been currently built in the world and one such dam is the Aswan High Dam that is situated in Egypt, and built across the Nile River by two main engineers, Maurice Fitzmaurice and Benjamin Baker. A study on this dam would reveal that it is approximately 3,600m in length and approximately 111m in height. The construction of the dam was completed in the year 1970, and its inauguration took place in January 1971. Other than the domestic uses that the dam has been to, it is used to generate electricity that approximates 10 billion kilowatts in a single year, much of which is supplied in the whole of Egypt. To this regard, it can be said that dams are of a great value to economies all over the world. A diagrammatic representation of the Aswan High Dam is as shown in the figure below. Dams are also constructed in various forms and natures and currently, the

Explain the causes of the increase in violence and deaths of young Essay

Explain the causes of the increase in violence and deaths of young people due to guns, knives and gangs and discuss the various policing challenges this presents - Essay Example In fact, there have been reports of children as young as 11 being murdered, not out of personal violence, but gang crimes such as the unfortunate murder of 11 year old Rhys Jones. Worse still is the fact that street brawls include more than just fists and kicks now – they include the very real possibility of knives and guns. To get an idea of how widespread the problem is, a 2007 report stated that there are over 600 to 700 young people between the ages of 10 to 19 involved in gang activity, having affected the lives of over 8100 others (Pitts, 2007). In 2009 it was reported that there has been a seventy five percent increase in the number of teenage stab victims over sixteen, and an almost staggering ninety percent increase in the number of stab victims under the age of sixteen (Blair, 2009). The questions is, however, when did this shift arise, and why has it arisen in the first place? What are the reasons that younger children are submerging themselves into this violent culture and finding themselves the dangerous target of an armed child? Where do these children get access to the weapons they use and who is responsible for making it possible? The main problem with gathering data on youth criminals is the fact that it is often a widespread grey area where the question of motivation is concerned. Is it possible for a child or teenage to act of completely independent motivation? If so, one may wonder where motivation arises from and is that source of motivation in any way to blame for the uncultured reaction of an individual not yet considered a mature adult by society. And if not, what are the factors influencing these crimes, and who are these children acting in support with. The obvious answer might be gang activity, but the further confusion arises when one considers that not all criminal youth activity is motivated by gangs, and vice versa. So how is one expected to offer some clarity into this blurred line? Perhaps one

Homeostasis And Goldfish Respiration Physical Education Essay

Homeostasis And Goldfish Respiration Physical Education Essay Every organism possesses a mechanism for maintaining homeostasis. Homeostasis is the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with changes in the external environment. Regulation of temperature is most definitely the most important aspect of homeostasis. Fish are cold-blooded animals. Most fish cannot control their internal body temperatures. Most fish body temperatures change with the temperature of the water around them. In order to obtain temperature homeostasis, the fish seek colder or warmer water. They lose metabolic heat through their gills. There are different types of metabolic adaptations in fish. Temperature and blood pressure are two. Cold-blooded animals must regulate their body temperature by moving. Literary Discussion Homeostasis and the Respiration of Goldfish What is Homeostasis? Homeostasis is the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with external changes (www.biology-online.org/dictionary/Homeostasis). The main function of homeostasis is to keep all the processes of the body stable even if there are variations in the weather and environment outside (http://www.buzzle.com/articles/what-is-homeostasis.html). Regulation of temperature is most definitely the most important aspect of homeostasis. Warm blooded animals are able to retain a more adjustable constant body temperature. In humans, homeostasis happens when the body regulates body temperature in an effort to maintain an internal temperature around 98.6 degrees Fahrenheit (http://www.biology-online.org/dictionary/Homeostasis). For instance, when it is hot outside your body sweats to cool off, and we shiver to warm up during the cold seasons. Unlike humans, most fish cannot control their internal body temperatures. Fish are cold-blooded creatures. Some fish have mechanisms to keep a healthy temperature. In order to obtain temperature homeostasis, the fish seek colder or warmer water. Certain types of fish such as tuna fish control their body temperature by a specialized heat exchange system of blood vessels. Most fish are poikilothermic which means their body temperature changes with the temperature of the water around them. For instance, if the top of a pond is frozen over, the fish swims to the bottom of the pond to try to stay at a comfortable temperature. All animals create heat from metabolic activity. Metabolic activity includes breaking down food and movement (http://www.ehow.com/facts_7433473_fish-homeostasis-different-water-temperatures.html). Animals such as fish lose metabolic heat through their gills. This happens because the heated blood that runs through vessels in the gills comes into close contact with the colder water outside, and all the heat is lo st. Many diseases are a result of disturbance of homeostasis. This condition is known as homeostatic imbalance. Every organism will lose efficiency in its control systems as it ages. Homeostatic imbalance is responsible for the physical changes associated with aging along with the internal environment. Inefficiencies gradually increase the risk for illness because of the unstable internal environment. It has been seen where alleged negative feedback mechanisms become overwhelmed and destructive positive feedback mechanisms then take over. Negative feedback is mainly how homeostasis is maintained, and positive feedback includes processes like blood clotting (http://www.biology-online.org/biology-forum/about2004.html). In maintaining homeostasis, the kidneys, liver, and brain are the organs in which play an important role. The kidneys are responsible for controlling blood water level, and regulation of salt and ion content in the blood. The liver performs the function of stabilizing carbohydrate metabolism and metabolizing toxic substances (http://www.buzzle.com/articles/what-is-homeostasis.htm.l) Whereas, the brain helps in controlling the autonomic nervous system and the endocrine system. Dehydration, hypertension, diabetes, hypoglycemia, etc are major homeostatic imbalance health problems. Homeostasis is extremely important for proper functioning of all human body systems. Enzymes even need a specific constant temperature to work at their optimum level. At higher temperatures, the enzymes will stop working. Homeostasis occurs to all humans, animals, and plants and is needed for us to stay healthy and alive. There are different types of metabolic adaptations in fish. Temperature and blood pressure are two examples. Body temperature for a fish mainly depends on the temperature of the water that the fish is in. This is the same for a fish in a tank, lake, pond, river, ocean, etc. A fish body adjusts to the temperature where the fish will be comfortable in the water. Cold-blooded animals cannot generate their own body heat; they must regulate their body temperature by moving. Absorptive and post absorptive are two metabolic states. Digestion, strength, respiration, salt and water balance, and heart rate are also included in this category. Glycolysis is an anaerobic metabolic pathway. Homeostasis in fish as well as in humans adjusts when the environment that it is in adjusts. If a fish is swimming in polluted water, the water is going to affect the fish. Its going to affect the fishs vision, the fishs breathing, and many other things. Just like polluted air causes humans to get a disease or any other illness, a fish can get a disease or illness as well. The temperature will affect the pace of the fish similar to the temperature affecting the pace of humans. Homeostasis, in biological terms means that the body is maintaining internal equilibrium to adjust internally and physiologically, in response to the external environmental changes(http://www.buzzle.com/articles/what-is-homeostasis.html). The main function of homeostasis is to keep all the processes of the body stable even if there are variations in the weather and environment outside (http://www.buzzle.com/articles/what-is-homeostasis.html). Regulation of temperature is most definitely the most important aspect of homeostasis.

Materials- Two fish Small sized container/fish tank Hot water Cold water Room temperature water Notebook/paper Pen/pencil Thermometer timer Procedure- First, set aside a bowl of water to get it to be room temperature. While that sits, create a table with three rows and eight columns. Label the first row experimental sample. Label the next two rows fish one and fish two. Label the columns room temperature, number of breaths, cold water temperature, breaths, hot water temperature, and breaths. Then, get extremely cold water and pour it into the container/fish bowl. Take the first fish and put it in the container with the cold water. Take the thermometer and put it in the bowl of water; wait till the meter stops moving. Record the temperature of the water. Next, set your timer to sixty seconds. Start the timer and count how many breaths the fish takes until the timer goes off. Record the time. Take the fish and thermometer out of the water and pour the water out. Pour the hot water into the container/fish tank and put the previous fish back into the container. Take the thermometer and sit it in the bowl until the meter stops. Record the temperature. Like before, set the timer to sixty seconds and count how many breaths the fish takes in that time. Record your results. After that, take the fish out along with the thermometer. Empty the container of the water. By this time the water that was set aside should be room temperature. Take that water and empty it into the container/fish tank and put the previous fish and thermometer in the bowl. Record the temperature of the water. Set the timer and count the breaths taken again. Record your results before taking the fish and thermometer out. Pour out the water. Repeat this process with the other fish and new water.

What is the mechanism in which fish breathe in water? A fish is any cold-blooded vertebrate animal that lives in water (http://www.myuniversalfacts.com/2006/03/how-do-fish-breathe.html). Fish live in nearly any water habitat and can be found in many different varieties of climatic conditions from near-freezing Arctic waters to the hot desert springs. Animals that live on land have a different respiratory system from aquatic animals such as fish. A fish is capable of breathing under water without taking frequent trips to the surface to breathe air unlike a whale which is a marine animal. This is because fish have gills. It is a process to fish breathing. First, water in the fishs surrounding enters its mouth. Water enters the mouth by the operculum and a very effective pumping system that involves the mouth. As a fish pumps water through the gills it opens and closes its mouth. Water is drawn into the mouth after the fish opens its mouth and the operculum closes. After water enters the fishs mouth it passes through a structure. This structure is called gill rakers. The gill rakers act as a filter system by straining out particles such as food or any other foreign particles that may have entered the mouth from the inflow of water. Next, the filtered water travels through the gill arches hence passing over the gills. Projected out into the water flow allows water to flow across the lamellae are gill filaments. Resulting, oxygen and carbon dioxide are exchanged directly across the capillary membrane. As water flows through the gills, the dissolved oxygen passes into blood circulating through the gill structures. The gill structures include the filaments and lamellae. Simultaneously, carbon dioxide which is the waste product, in the fishs bloodstream passes into the water. It is then carried away and out of the body through the operculum. This is the process by which fish breathe also know as respiration.

Media Ownership :: essays papers

Media Ownership Ownership of the media by a small handful of companies has created several problems for democracy since it’s existence. Because the media has been such a major source of information for us Americans we must learn to be skeptical of these large corporations and their motives. Commercialism and the lack of diversity of the media are two such problems that have been created due to these large corporations. The main source of money for any media outlet, whether it is CNN or the local newspaper, is from advertisers, not the audiences like you would expect. â€Å"In a survey of 118 news directors around the country, more than half, 53 percent, reported that advertisers pressure them to kill negative stories or run positive ones.† News directors have also reported that outside TV consultants have been brought in to stations to critique their newscasts and improve ratings by often issuing blanket edicts about what should and should not be covered in doer to attract the most advertising dollars. (Just, 1) This fact now being known makes us aware that the media is often swayed from criticism of the products or mistakes of the corporations that give them this money. Important defects or corporate issues that we need to know about have possibly gone unannounced due to the fear of losing sponsors and profit. The only way to guarantee diversity of opinion in the media is to have diverse ownership over it. The airwaves are a limited resource with a few channels still remaining. The Federal Communications Act says that the airwaves belong to the public, which has somehow has gone ignored over the years. Having been exposed to a less diverse range of ideas over the past few decades has left us assuming that what we see and hear in the media is all that there is out there. This is obviously no way to maintain an active marketplace of diverse ideas and opinions. This is defiantly no way to keep a true democracy. (Bagdikian, 2-3) As you can see the corporate ownership of the media has become a problem to our existing democracy. Not only has the media become extremely commercialized it has also taken away the diversity that we need to make an honest judgment about something of importance to us.

Ancient Greek Musical Instruments

Lyra: originally called Chelys, because of the tortoise shell used as its sound box. According to Nicomachus of Gerasa (Ist cent. AD), the tortoise-shell Lyra was invented by god Hermes, who gave it to Orpheus. â€Å"Orpheus taught Thamyris and Linos, and Linos taught Hercules. When Orpheus was killed by the Thracian women, his lyra was thrown into the sea, and washed ashore at Antissa, a city of Lesbos, where it was found by fishermen, who brought it to Terpander, who in turn carried it to Egypt and presented it to the Egyptian priests as his own creation. We don't know how many strings the original Lyras had. By the time of Terpander (8th-7th cent. BC) Lyra was a seven stringed instrument and from many ancient sources we know that this type remained in use for a long time during the classical period. The addition of an eighth string in the 6th century BC is credited by Nicomachus of Gerasa to Pythagoras. By the fifth century there were Lyras with anything from 9 to 12 strings. The strings (neura) were made of animal gut of sinew, but there are also references of strings made of linen or hemp.Lyra was mainly used for the musical education of the young, and by amateur players in general. Cithara plucked instrument with 5 strings originally, but later with as many as 12 strings. Cithara was bigger than the Lyra and it was the principal concert instrument played by professional musicians, the citharodes. According to Plutarch, cithara was designed by Cepion, a student of Terpander. Many instrument names like guitar, cittern, zither etc. derive from the word cithara. Barbitos or Barbiton is an instrument of the Lyra family and resembles a Lyra, but it has longer arms and narrower sound box.Musicians of the School of Lesbos, like Alcaeus and Sappho, are frequently depicted in vases playing the Barbitos. Phorminx probably the oldest of the Cithara type instruments. From references in ancient sources (Homer, Hesiod, Aristophanes) we know that Phorminx was richly dec orated with gold and ivory, and accompanied the singing of the epic singers called rhapsodes. Epigonion belongs to the psaltery family and it is the instrument with the largest number of strings, sometimes as many as forty (Polydeuces).It may owe its name to the fact that it was played ‘on the knee' – Greek ‘epi gonu', or maybe because its inventor was someone named Epigonus. Pandouris or pandourion, also called trichord because it had three strings, is the first fretted instrument known, forerunner of the various families of lutes worldwide. Source of our knowledge about this instrument is the Mantineia marble (4th cent BC, now exhibited at Athens Archaeological Museum) depicting the mythical contest between Apollo and Marsyas, where Pandouris is being played by a muse seated on a rock.

APA Snippets and Style Writing Pointers to Help TCL Nursing Students Write Excellent Papers Datatel Number Technical College of the Lowcountry Course Number Abstract All papers should have an abstract. An abstract is a brief, comprehensive summary of the contents of the paper, including the purpose and major findings. The abstract should be well organized, concise and specific. The abstract should be one paragraph of no more than 120 words on a page by itself. Other features of an abstract include double-spacing, one inch margins without indentation, and Times Roman or Courier 12 font.APA Snippets and Style Writing Pointers to Help TCL Nursing Students Write Excellent Papers The aim of this article is to discuss the varieties of pain assessments, and to determine under which circumstances each assessment is most appropriate. Pain is rated differently by each patient, and is subjective to many factors in the patient's life, including but not limited to culture and past experiences wit h pain. Since pain may have an effect on all aspects of a patient's life, healthcare providers must strive to most properly identify the amount of pain in order to properly control it.Symptoms such as â€Å"crying, elected temperature, facial grimacing, groaning, moaning, guarding of the affected area, loss of sleep, nausea, vomiting, restlessness, rise in blood pressure, rise in respiratory rate, and tachycardia† are typical indicators that a patient is in pain; but how much pain? Healthcare providers, namely nurses, use a system of scales and work with the patient to rate their pain. Nurses must be aware of the different pain rating scales available in order to most accurately assess a patient's pain level.A nurse must not only be able to determine which pain scale is most appropriate for the patient to identify and express his or her pain level, but also be able to carefully interpret and evaluate the scores. For example, the pain scale that is appropriate for a fully func tioning adult will differ from one that is appropriate for a child and differ from one that is appropriate for a patient affected by dementia, etc. A variety of unidimensional scales quantify the intensity of the pain and are more simple; while multidimensional scales do so plus identify the pain quality, uration, and any relieving factors, and are more complex. If time permits, a nurse may choose to use a combination of pain assessments in order to be as thorough as possible. Nurses can implement the use of a variety of pain assessments reviewed in this article into their patient's shift assessment. A nurse may choose to use a more complex, thorough multidimensional scale upon his or her patient's admission assessment, and then use a more simple, quick unidimensional scale upon his or her patient's regularly scheduled shift assessments.Regardless of the type of scale being used, a nurse must always use â€Å"effective and sensitive communication with the patient to assist in expre ssions of pain. † Nurses must listen to their patient and accurately document their patient's subjective descriptions of the pain. Also, nurses should allow their patients ample amount of time to respond to their questions, which should also be open-ended questions. After the doctor has reviewed the pain assessment and ordered meds, the â€Å"effects of analgesia should be monitored closely and recorded in nursing notes to maintain continuity of patient care. In conclusion, nurses should assess the patient's abilities, then choose and tailor the pain assessment to the patient's needs. Assessments are of immeasurable importance as they have a direct effect on the patient's quality of life. The more extensive of knowledge a nurse has of the plethora of pain assessments to choose from, the more he or she can also select the most appropriate pain scale per the patient, which in turn will have the greatest impact on the patient's progress.

Kangaroo Facts

Kangaroo Facts Kangaroos are marsupials that are indigenous to the Australian continent. Their scientific name, Macropus, is derived from two Greek words meaning long foot (makros pous). Their most distinctive characteristics are their large hind legs, long feet, and large tail. Kangaroos are unique in that they are the only animals of their size that use hopping as their primary means of movement. Fast Facts: Kangaroo Scientific Name: MacropusCommon Names: Kangaroo, RooOrder: DiprotodontiaBasic Animal Group: MammalsDistinguishing Characteristics: Large hind legs, long feet, large tail and pouch (females)Size: 3 - 7 feet in heightWeight: 50 - 200 poundsLife Span: 8 - 23 yearsDiet: HerbivoreHabitat: Forests, plains, savannas, and woodlands in Australia and TasmaniaPopulation: Approximately 40 - 50 millionConservation Status: Least concernFun Fact: Like camels, kangaroos may go for periods of time without drinking water. Description Kangaroos are best known for their powerful hind legs, their large feet, and their long powerful tails. They use their legs and feet to hop around, which is their basic means of locomotion, and their tails for balance. Like other marsupials, females have a permanent pouch for raising their young.  A kangaroos pouch is technically called a marsupium and it performs a number of functions. The female kangaroos breasts, which she uses to nurse her young, are inside her pouch. The pouch also functions similarly to an incubator to allow a joey (baby) to fully develop. Lastly, the pouch has a safety function in that it helps to protect the females young from predators.   Kangaroos are usually between 3 to 7 feet in height. They can weigh up to approximately 200 pounds. Other physical characteristics of kangaroos are their relatively small heads with their large, round ears. Due to their hopping ability, they can leap over long distances. Some males may leap to almost 30 feet in one leap. Eastern Grey Kangaroo, Murramarang National park, New South Wales, Australia.   J and C Sohns/Getty Images Plus Habitat and Distribution Kangaroos live in Australia, Tasmania, and surrounding islands in a variety of habitats such as forests, woodlands, plains, and savannas. Depending on the species, kangaroos occupy different niches in the ecosystem. Diet and Behavior Kangaroos are herbivores and their diet consists mainly of a variety of plants such as grasses, shrubs and flowers. Some species may also eat fungi and moss. Kangaroos live in groups called mobs, also known as troops or herds. These mobs are usually headed by the dominant male in the group.   Similar to cows, kangaroos may regurgitate their food to chew it as cud and then swallow once more. This behavior is much rarer in kangaroos than in ruminant animals. Kangaroo stomachs differ from those of cows and similar animals; while both kangaroos and cows have chambered stomachs, the fermentation process in their respective stomachs is different. Unlike cows, the process in kangaroos doesnt produce as much methane, so kangaroos dont contribute as much to methane emissions globally as cows. Kangaroos are usually active at night and in the early morning hours, but their overall activity pattern is varied. Their rest periods are restricted almost exclusively to a diurnal (during the day) pattern. Similar to camels, they may go for periods of time without drinking water due to their relative inactivity during the day when it is hotter. Since their diet consists of plants, their water needs can be largely satisfied by the water content present in the plants that they eat. Reproduction and Offspring Eastern Grey Kangaroo with Joey in Pouch.   Gary Lewis/Photolibrary/Getty Images Plus Kangaroos have a varied breeding season. Reproduction takes place all year long, but the Australian summer months of December to February are the most common. Male kangaroos may flex their muscles to attract females and can fight for the right to breed with females. Females usually produce one baby kangaroo, called a joey. After becoming impregnated, a kangaroo will have her baby after a gestation period of a little longer than a month (approximately 36 days). The baby joey weighs about .03 of an ounce and is less than one inch in length when born, about the size of a grape. After birth, the joey will use its forelimbs to travel through its mothers fur to her pouch, where it will remain for the first few months of its life. After five to nine months, depending on the species, the joey will typically leave the pouch for brief periods of time. After about nine to eleven months, the joey will leave its mothers pouch for good. Females can enter heat after giving birth, so they may become pregnant while a joey is still nursing in her pouch. The developing baby will enter a dormant state that coincides with their older sibling leaving the mothers pouch. When the older sibling leaves the pouch, the mothers body will send hormonal signals to the developing baby so that it will resume its development. A similar process occurs if the mother is pregnant and the older joey dies in her pouch. Conservation Status Kangaroos are designated as least concern by the International Union for Conservation of Nature (IUCN). Their population is very abundant and by most estimates, there are more kangaroos in Australia than people. Estimates range from a population of 40 to 50 million kangaroos, which continues to increase. Humans are the main threat to kangaroos since they are hunted for both their meat and their hides. Humans can also contribute to the loss of kangaroo habitat due to land clearing for development. Predator threats include dingos and foxes. Kangaroos use their teeth, claws, and strong hind legs as defense mechanisms against such predators. Species There are four major species of kangaroos. The red kangaroo (Macropus rufus) is the largest. Males of the species have red/brown fur. Other species include the eastern grey kangaroo (Macropus giganteus), the western grey kangaroo (Macropus fuliginosus), and the antilopine kangaroo (Macropus antilopinus). The eastern grey kangaroo is the second largest species and is known as the great grey species, while the western grey kangaroo is also known as the black-faced kangaroo due to its distinctive facial coloring. The antilopines name means antelope-like and they are found in northern Australia. Some scientists consider there to be six species of kangaroo, including two species of wallaroo (Macropus robustus and Macropus bernardus). Wallaroos are considered to be closely related to both wallabies and kangaroos. Herd of kangaroos at twilight (Coombabah Lake, QLD, Australia).    Kangaroos and Humans Humans and kangaroos have a long and varied interaction pattern with one another. Humans have long used kangaroos for food, clothing, and some types of shelter. Due to their increasing numbers, kangaroos can be viewed as pests, particularly by farmers when kangaroos compete for grazing land. Kangaroos are often present in grasslands and areas that are typical farmland so resource competition may take place. Kangaroos are not typically aggressive when grazing. The situation of farmers seeing kangaroos as pests is similar to how many in the United States may see deer as pests. Sources Britannica, The Editors of Encyclopaedia. Kangaroo.

Bicycle Propulsion Systems

Bicycle Propulsion Systems    1.Abstract This report documents the development of bicycle propulsion systems over time and mentions the changes made to make the bicycle more efficient, safe, faster and resistant. It defines what a bicycle’s drivetrain system is in a few words and what they are used for on a bicycle. It includes brief information about 4 of the first bicycles made in the 1800s and refers to the changes in design and materials used for these bicycles. It also consists information of the 2 main bicycles used today and the improvements they have had compared to the older bicycles. At last, this report recommends improvements that could be made to the bicycle to make it more efficient. 3.Nomenclature Km/h = kilometers per hour Kg = kilograms Torque = a force that causes rotation Cadence = the number of revolutions of the crank per minute 4.Introduction Public transportation has changed and improved over a great period of time. These improvements have helped make transp ortation ,from one location to another, much easier. The bicycle is a great example of a method of transportation that has gone through a lot of improvements so that it is easier to use, faster, safer and more damage resistant. All this has happened by engineers taking into consideration the materials they use and the design of the bicycle. 5.Discussion and Analysis of Material 5.1 Bicycle Drivetrain Systems (Appendix 1 and 2) Bicycle Drivetrain Systems are used to transmit the rider’s power to the drive wheels in order to move the bicycle forward. Nowadays, most drivetrain systems include mechanisms that are used to convert speed and torque via gear ratios. Over the years propulsion systems for the bicycle have ranged from the rider’s legs, to the modern drivetrain systems that include gears and pedals. 5.2 History (Appendix 3) Over the past couple of centuries many different bicycles have been invented that have different characteristics in order to improve safety and efficiency, but still had a similar structure. Many of the different developed bicycles include: Hobby Horse (Appendix 4) The Hobby Horse was invented in 1817, by the German inventor, Baron Karl Drais. This bicycle had a primitive design and did not include a drivetrain. It was a 23kg bicycle which was made out of wood, including the wheels. It also included a leather saddle for the rider to sit on, and resembled a modern handlebar. The rider’s feet was the propulsion system for this bicycle. This meant that the rider wouldn’t be able to go very fast and would require a great amount of effort to move it forward due to its weight. It would also be difficult to transfer the bicycle uphill, thus the rider would have to carry it. Whilst going downhill, the lack of brakes would cause the bicycle to travel at a fast speed without anything, other than the rider’s feet, to stop it. Velocipede (Appendix 5) The Velocipede was invented in 1858 by the Fr ench Michaux company. This bicycle was a great development from the Hobby Horse. It first had a cast iron frame which was then changed to wrought iron for better damage resistance. The seat featured suspension which was inspired by the suspension used in wagons. Although, the bicycle was not comfortable to ride, hence why it’s also called the â€Å"Boneshaker†. The wheels were wooden but consisted of iron tyres. It also included pedals on the axle of the front wheel as the bicycle’s propulsion system. The pedals would allow the rider to use less effort, compared to the Hobby Horse, to move the bicycle forward. This bicycle also consists of the introduction of a first brake, which included a metal lever that pressed a wooden pad against the rear wheel, making it much safer as it has the capability of stopping, though the wooden pad would wear out due to the friction between the pad and the wheel. Penny Farthing (Appendix 6) The Penny Farthing was invented in 1869 by French, Eugene Meyer. The bicycle’s design was based on the desire to make it faster, thus using it for sport. Since gears were not invented yet, the front wheel’s size was increased so it would travel a longer distance after one full rotation. The frame weight was reduced to increase riding comfort including solid rubber tires, and the use of hollow steel tubes made it lighter. With the introduction of spokes and ball bearings, the wheels were also improved. The Penny Farthing would reach top speeds of 40km/h, but despite its advantages it had many disadvantages. It required a running start and a mounting step for riders to be able to mount it. To stop, the rider would require to jump off the bike. The higher centre of gravity on the bicycle would mean that if the rider fell they would have great accident. And at last, if the rider went over a bump they would be sent flying, leading to a fatal accident. The Penny Farthing’s propulsion system were stil l the pedals, although, their positioning on the bigger front wheel would require riders with tall legs to ride them. Due to the bigger wheel, one rotation of the pedals would allow the bicycle to cover a longer distance, hence why it is faster than previous bicycles. This design might my the bicycle faster and more efficient, but it was more dangerous due to the height and centre of gravity of the bike, the lack of feasible brakes and the high speeds it can reach. The Rover (Appendix 7) The Rover was invented in 1885 by English John Kemp Starley. This bicycle was chain driven and was also known as the â€Å"Safety Bicycle†. It featured equal sized wheels and a diamond frame, used to equally distribute the forces throughout the bicycle’s frame, though it still lacked a seat tube. The solid rubber tires were also replaced in 1888 with pneumatic tires, which made it more comfortable to ride. The original model of The Rover used treadles to turn the rear wheels, but t he later updated model used a chain drive which consisted of a large front sprocket and a small rear sprocket used to multiply the revolutions of the pedals without the need of a large front wheel. The pedals were more centred putting the rider’s feet away from the front wheel, and the centre of gravity was lower making it easier for the rider to stop by putting their feet on the ground. To also better stop the bicycle, it included a lever which pushes a metal pad onto the front wheel. This bicycle was much safer due to its frame design and its low centre of gravity. It had increased efficiency due to the positioning of the pedals and the two same sized wheels whilst still being capable of travelling at high speeds with the brake being able to stop the bicycle if needed. The design of the handlebar also helped to improve the handling of the bicycle. The use of metal on the frame and on the chain mechanism also made it resistant from damage. Although, with the introduction o f the new chain mechanism, pebbles or sticks could get caught in the chain, possibly damaging the mechanism. 5.3 The modern bicycles Today there is a variety of bicycles that are used for different situations. To be able to adapt to the different situations, the bicycles have different characteristics but still have similarities structure-wise. The 2 main types are mountain bikes and racing bikes. Mountain Bikes (Appendix 8) Mountain bikes are bicycles designed for off-road riding. They are similar to other bikes but consist features that help enhance performance and durability on rough terrain. They consist of suspension on the frame and fork making the ride on rough terrain more comfortable, knobby tires which adds more grip on the wheels, heavy duty wheels that add durability, and more powerful brakes to help stop the bike instantly when on the rough terrain. The bicycle’s propulsion system includes derailleur gears (Appendix 2) that consists of a crankset for th e rotation of the bicycle’s pedals, a cogset which is a set of different sized metal cogs or sprockets that are used as the gears, and a chain that links the cogset with the crankset. Different gears provide different torque and speed and requires different amounts of effort to rotate the pedals. The higher the gear, the more torque, speed and effort. The gears are controlled by a shifter which is connected to the gearing gearing mechanism by a cable. Mountain bikes tend to have up to 30 gears, yet mountain bikers choose to use 10 or 9 speed bikes due to the lighter weight and less complexity. The mountain bikes are very efficient and safe bicycle as they include disk brakes that help with instantaneous stopping, a gearing system that helps reduce the amount of effort the rider will have to use and is adaptable to different types of roads, and suspension that provides comfort. Racing Bike (Appendix 9) Racing bikes are designed for competitive road cycling. Its main char acteristics are its light weight for higher speeds, and its stiffness due to the lack of suspension also to achieve high speeds with the sacrifice of comfort. The handlebars are designed and positioned lower than the saddle so that the rider has a more aerodynamic posture. The front and back wheels are positioned close together to allow for quick handling. For the propulsion system the bicycle uses a derailleur system similar to the Mountain Bike. The gear ratios have close spacing so that the rider can pedal at the optimum cadence. To shift gears the bicycle consists of an electronic shifting system. The switch is connected wired or wirelessly to a battery pack and to a small electric motor that is used to drive the derailleur, moving the chain between the cogs. This improvement allows for the rider to switch gears faster. The Racing Bike is quite efficient in terms of speed, and quite safe as it includes disk brakes that stop the bike instantly with the exception of knobby whe els as it would decrease the speed of the bike. The materials manufactures use for the frame e.g. Carbon fibre, cause the bike to be light in weight and capable of travelling at faster speeds. 6.Conclusions There have been many major developments in public transport over the years, with the bicycle as a great example. Many improvements have been made to the bicycle and the methods it uses for the rider to move it forwards. The introduction of new drivetrain systems and the vast use of different materials according to their properties are the cause of these improvements. The invention of, more complex, propulsion and brake systems have helped improve the efficiency and safety of the bicycle and the implementation of stronger and lighter materials has increased the bicycle’s damage resistance and has made it capable of reaching higher speeds (Appendix 10) with less effort required by the rider. Also improvements on the seat and the suspension on the bicycle have contributed to make it a more comfortable method of transportation. 7.Recommendations The bicycle has had great developments over the years, though more improvements can be made in order to make the bicycle safer, faster and more efficient. Such improvements may include: Adding a cover, made of a light plastic, for the gearing system so that nothing can get caught in the mechanism, running the brake lines through the frame of the bicycle so there aren’t any cords hanging, adding a cogset to the front wheel making it a 2-wheel drive thus making it faster. 8.References Crazyguyonabike April 15, 2009, The Hobby Horse: 1817 – Karl Drais and his running machine. https://www.crazyguyonabike.com/doc/page/?page_id=40616 , (accessed 1/3/2017) Crazyguyonabike May 2, 2007, The Boneshaker: 1867 – Pierre Lallement, the Michaux family and their velocipede. https://www.crazyguyonabike.com/doc/page/?page_id=40617 , (accessed 1/3/2017) Crazyguyonabike July 2, 2007, The P enny Farthing: 1878 – James Starley and his ordinaries . https://www.crazyguyonabike.com/doc/page/?page_id=40618 , (accessed 1/3/2017) Crazyguyonabike March 27, 2009, The Rover: 1885 – The modern bicycle born in England. https://www.crazyguyonabike.com/doc/page/?o=tS&page_id=40621&v=9Y , (accessed 1/3/2017) Wikipedia January 6, 2017, Racing Bicycle. https://en.wikipedia.org/wiki/Racing_bicycle , (accessed 2/3/2017) Wikipedia February 23, 2017, Mountain bike. https://en.wikipedia.org/wiki/Mountain_bike , (accessed 2/3/2017) 9.Appendices Appendix 1 Appendix 2 Appendix 3 Appendix 4 Appendix 5 Appendix 6 Appendix 7 Appendix 8 Appendix 9 Appendix 10
