Osmosis in Different Concentrations

I am going to investigate osmosis when potato is placed in different   concentrations of sucrose. I am aiming to witness osmosis in 5   different concentrations of sucrose. I will use 5 varying concentrations so that I have a wider spread to compare the results,   and check that I don’t have any anomalies Prediction Osmosis  is the process of diffusion of water molecules from a weaker   solution into a stronger solution, through a semi  permeable membrane.The tiny pores in the membrane of the potatoes will allow the water   molecules to go in and out of the potato cell, depending on the   concentration gradient between the potato and the sucrose solution. If   the  water concentration  is lower in the potato than in the sucrose   solution, then water will pass from the sucrose solution into the   potato, and it will gain weight.If there is a higher concentration of   water in the potato, then the water will go out of the potato and into   the sucr ose solution, as osmosis is the movement of water molecules   from a region of high concentration to a region of low concentration,   through a semi permeable membrane. So, I predict that the higher the   concentration of sucrose, the lower the weight of the potato as water   from the potato diffuses into the sucrose solution. Predicted graph of results: [IMAGE] Apparatus * 6 test tubes * 6 different concentrations of sucrose solutions * Potato Potato cutter/core * Digital measuring scales * Measuring cylinders * Knife * Test tube racks * Tissue paper Method I will need 1 piece of potato in each tube. As there are 15 tubes I   will have to calculate how many pieces I will need altogether. I think   this would be a suitable calculation: 1Ãâ€"15=15. So, I will pierce out   some pieces of a potato using a core, and then cut 15 slices with a   knife. Then I will measure 10ml of each of the 6 sucrose solutions   using a measuring cylinder. I will be given these differe nt   concentrated solutions in the general laboratory.I will label the   tubes 1 to 15 and fill each one with 10ml of the solution. Tube 1-3 will have a concentration of 0 Tube 4-6 will have a concentration of 0. 4 Tube 7-9 will have a concentration of 0. 8 Tube 10-12 will have a concentration of 1. 2 Tube 13-15 will have a concentration of 1. 4 I will measure each slice on the measuring scales to identify each   potato slice with its weight before and after immersion in the   sucrose. Having measured each slice on the scale and recorded its   weight, I will then place the slices in the test tube containing the   solution for 24 hours.Then I will empty the solution from the test   tube by pouring it in the sink and remove the potatoes by hand and   place them one by one on the scale. For accuracy, I will make sure   that I wipe off any excess solution on the scale before placing each   new slice on it. I will record the weight after placing them in the   soluti on for 24 hours. This process will be repeated for tubes 1 to 15   and the results will be noted in a table and then plotted on a line   graph. I will make this a fair test by only varying the concentration of   sucrose and the size of the potato slices, but keeping everything else   the same.The same potato must be used for the whole experiment or   otherwise, the results would differ as the age and sizes might be   different, which means one potato might have more water in it than the   other. I will use a 10ml measuring cylinder so that I can accurately   measure the exact amount of sucrose needed. As the cylinder measures   different sucrose solutions, it has to be washed out each time I measure   another 10ml of sucrose for the next tube, because it may be   contaminated with the different sucrose’s.All the tubes will be kept for   the same time, in the same place, so that the uncontrollable   temperature would not affect the tubes separately. I will not be able to control: * Temperature – because I won’t be in the laboratory for 24 hours,   and the temperature could change in the night, or morning. *Temperature of solution- because I was not able to obtain a thermometer and I was not in the laboratory for 24 hours so it could change. * Weighing scales – because these are digital and therefore, it   produces results by itself. I will be able to control: Concentrations of sucrose – they are already measured * Time – I will do the experiment, and come back the next day at the   same time, and promptly record the results *weight of the potato- I weighed the potato slices before the experiment. For safety in the laboratory, I will be very careful using the sharp   knife which I will be using to cut the potatoes with. I will make sure   that I have an overall so that my clothes don’t get dirty if the   solutions spills. I will remember not to put potatoes or sucrose in my   mouth as they might have been infected by chemicals in the lab, which   are poisonous.I will measure the weight of the potato in grams, and the concentration of sucrose in percentage. I am expecting everything to work out well as I have a perfectly good   method but if I feel that the results may be wrong, I will repeat my   experiment. Preliminary results These are my results: This experiment supports my plan and prediction. The carrot gains   weight in normal water, and decreases weight in concentrated sugar   solutions. By doing this experiment, I believe that my method is good, and it   will work. I think I should specifically be aware of the scales,   because they alter a lot.However, this was carried out at home, so   the cooking scales may have not been so accurate, as accuracy is not   very important in cooking. Results these are my first results. They proved to be wrong. This mistake   would have been made my human. I assume that I used two different   scales, and have got all the weights jumbled up. The weight taken at   the beginning is also not correct, so I may have made a mistake right   from the start. Concentration of sucrose. | Weight before| Weight after| 0| 1. 28| | 0| 1. 33| | 0| 1. 29| | 0. 4| 1. 29| | 0. 4| 1. 27| | 0. 4| 1. 2| | 0. 8| 1. 31| | 0. 8| 1. 3| | 0. 8| 1. 3| | 1. 2| 1. 29| | 1. 2| 1. 37| | 1. 2| 1. 27| | 1. 6| 1. 26| | 1. 6| 1. 3| | 1. 6| 1. 31| | Conclusion I found out that as the concentration of sucrose increases, the weight   of the potato decreases. In water it gained 1. 26 grams, but in 1 Sucrose   solution, it lost 0. 16 grams. My prediction supports my conclusion. I have calculated the average change in weight to have a simple, clear   idea where the experiment is leading me to. Instead of having a large   number of weights, I combined them into one by averaging them.I found   the average by adding the weight gain/loss for each tube and divided   it by three. To find the percenta ge, I multiplied that decimal by 100. I drew a line graph, and then a line of best fit, which is sloping   downwards, negatively. This proves that the weight is getting lower as   the percentage of the sucrose concentration is getting higher. In my investigation I found a definite relationship between the 2   variables – weight and concentration of sucrose. Any increase in   sucrose concentration led to a decrease in weight. The prediction is supported by the evidence of the graph.Although   there is one anomaly, all the other results stand out and give a   straight line of best fit – exactly as I predicted. The point of   early plasmolysis is where the concentration of sucrose and potato   are even. There is no osmosis taking place at that point. As I said in   my plan, if the water concentration is lower in the potato than in the   sucrose solution, then water will pass from the sucrose solution into   the potato, and it will gain weight. If the re is a higher concentration of water in the potato, then the water will go out of   the potato and into the sucrose solution.This is because osmosis is   the movement of water molecules from a region of high concentration to   a region of low concentration, through a semi permeable membrane. The up raise of sucrose is the downfall of potato mass. [IMAGE] Osmosis In osmosis, water diffuses through a semi-permeable membrane. This diagram illustrates the concentrated sugar solution, separated   from dilute sucrose solution by a selectively permeable membrane. This   has pores (holes) in it which are very small, and selects what it   wants to let through i. e. small molecules.Water molecules are very   small. Each one is made of two hydrogen atoms and one oxygen atom. However, sugar molecules are many times larger. In potatoes, the pores   of the membrane only let the water through. There is a higher concentration of sugar molecules on the right-hand   side of the mem brane in the diagram, than in the left-hand side. Sugar   molecules would diffuse from the concentrated solution into the dilute   one until they were evenly spread out if there was no membrane, but   they cannot do this as the pores are too small for the sugar to get   through the membrane.Therefore, the small water molecules diffuse   into the concentrated sugar solution, to make it more dilute. This process is called osmosis. It is the diffusion of water molecules   from a place where they are in a higher concentration, to a place   where they are in a lower concentration, through a selectively   permeable membrane. Potato cells plasmolyse in concentrated solutions. This diagram   illustrates a plant cell[IMAGE] (which is similar to a potato cell) in   a concentrated solution. It will lose water by osmosis. The cytoplasm   and the vacuole will shrink.The cell membrane is semi-permeable and the vacuole contains a sucrose   solution. So when a cell is placed in distilled water (high   concentration) water will move across the semi-permeable membrane into   the cell (lower water concentration) by osmosis, making the cell   swell. This cell is called ‘turgid’. In potato cells, the cells would   increase in length, volume and weight because of the extra water in   the potato. If the potato was to be placed in a lower concentration, then the   opposite would happen, because water would move out of the cell into   the solution.If the solution is very concentrated, then a lot of water will diffuse   out of the cell. The cytoplasm and vacuole will keep shrinking, but   the cell wall will not as it is too stiff. As the cytoplasm shrinks   further and further into the centre of the cell, the cell wall gets   left behind. The cell membrane, surrounding the cytoplasm, tears away   from the cell wall. If this happens, the cell is said to be   plasmolysed. The potato will therefore, decrease in length, volume and   weight. Plasmolysis is the point where the membrane is totally detached from   its ell wall, and the potato is killed. Evaluation my experiment shows some accurate results. It concludes the experiment, and proves my prediction. My   final results were quite reliable; due to the precautions I took to make this  a fair test. The graph has a straight slope pointing downwards, which is the   clearest way to understand my prediction. All of them are not that   closely together, neither far away, so a line of best fit joins some   tips of the points, and causes it to go straight down.I have one anomalous result, which falls on 0 on the x axis. This   occurred in tube 5, which contained a concentration of 0. 4. Perhaps I did not   carry out that properly. These were the main problems in carrying out the experiment:- * Scales kept moving * Difficult to get out the potato from the core * Potatoes get stuck in tube. * Solution is still left after wiping the potato and the scales * Different scales * couldn’t control the temperature the point of early plasmolysis would not be valid.This is because   I have just plotted it on the graph on a line which suits my results. To prove that it is the right point, I would have to do another   experiment to find that out. The other evidence is likely to be valid, because as all the evidence   links to the results. My investigation is fair because I did not   change many things, expect the concentration of sucrose. I think that I have collected quite a lot of evidence to support my   conclusion. The result table is the main source of evidence.I could   try investigating with more percentages of sucrose concentration, the   size of the potato and have more short intervals between the sucrose’s. This would have a more spread to the results, and therefore, results   can be compared and evaluated more thoroughly. They would be very   accurate as well as reliable. As I have an anoma ly, my evidence may not be extremely correct. I   would have to do more research to what I have already done (in the   conclusion) on osmosis, and see what actually happens, and see if it   occurs in plant cells all the time.If I were to repeat the experiment, I would use a very accurate scale,   so that results would come out accurately and then I would have a accurate   average. The graph will be fairly accurate. I would also make sure   that the scale and the potato slices are properly wiped. This is   because if they are not wiped, the weight would increase, and will not   be accurate. I could use a syringe or a burette to measure the 10ml of   sucrose solution, because those two apparatus are very accurate.I would do several more experiments with bigger sizes of potatoes to   obtain more evidence to support my conclusion. I will also do some   research on osmosis, and this will make me certain of my evidence if I   have many to compare with. I will agree with the majority. Overall, I am very pleased with these results and with the evidence I   have so far, that osmosis occurs when there is a high concentration   and a low concentration, both aside a semi-permeable membrane. The   lower concentrated substance diffuses through the membrane to where   there is the higher concentrated substance.

Comparison Between Joe Keller and Willy Loman Essay

Death of a Salesman and All of My Sons, two different plays written by distinguished playwright Arthur Miller, yet the two main characters Joe Keller and Willy Loman are notably identical to one another. Although both are not faced with similar situations, both Keller and Loman handle their situations with an ignorant and shallow mindset towards the world. Keller and Loman have significant tragic flaws which ultimately lead to their demise. Both characters are unable to accept reality the way others are capable of, the â€Å"American dream† has been corrupted and misinterpreted in their feeble minds, and abandonment has plagued them throughout their lives. The â€Å"American dream† seems to play a monumental role in distinguishing what is essential to be successful. Joe Keller believes that his son, Chris, deserves the business he built from the ground, up and does absolutely everything in his power to ensure that Chris will obtain Joe’s business. In Joe’s eyes, risking the lives of soldiers, making an abomination out of his former â€Å"best friend†, and separating a family in order to keep his business running smoothly is deemed more worthy than doing the right thing. Joe feels that he has done the right thing because he carried out these actions for his family. Willy Loman’s interpretation of the â€Å"American dream† is a tad bit more extravagant; Willy believes that the key to success is a matter of whether a person is well-liked or not. Throughout the course of his professional career as a salesman, Willy constantly concocts lies stating how he is well-liked all over the Northeast, as well as his weekly salary. Willy also tried to bring the dream upon his son Biff. While Willy’s son Biff was a student in high school, Willy continuously fed Biff these fantasies that one day, Biff would become a great football player. Willy preferred brawn over brains in Biff. Willy was unable to live the American dream and thus ventured on through Biff vicariously. When Biff decided not to finish summer school and then explore new endeavors out west, Willy began to grow furious with Biff because he was unable to hover over Biff and â€Å"lead† him toward success. In All of My Sons, Joe Keller is unable to perceive reality with his involvement in the busted airplane heads which led to the death of twenty-one soldiers of the Air Force. We the readers notice that the lie Joe tells to others has been so commonly practiced that it’s no longer a fabrication of Joe’s imagination, but in his opinion, the genuine truth. Joe becomes obsessive over Chris inheritance of Joe’s business and it seems as though he does this so that in the event that someone reveals the truth to Chris, there is no possible way that Chris could be ashamed after what his father did for him. Unfortunately for Joe, the truth is revealed too soon and Chris no longer is willing to follow in his father’s â€Å"murderous† footsteps; instead Chris is enraged by his father’s past actions and vows to either turn his father in or kill him. Willy Loman is beaten down by his failure of him and his son to live up to his expectations. Unlike Joe, Willy’s altered perception of reality conflicts with his everyday life. He is over exhausted and constantly has flashbacks which deceive Willy’s perception of reality. His flashbacks usually consist of Willy’s overbearing confidence in Biff’s future. Willy also has flashbacks where his successful brother shows up. To stack himself up against his brother’s success, Willy lies about how his business is prospering and how he nearly at the top of the metaphorical food chain in the sales world. In reality however, Willy is a struggling business man who barely makes ends meet. He needs to ask his friend Charley for money just to pay bills and make it seem like he is still making money so he is not a failure in the eyes of others. Willy resorts to these flashbacks when he faces adversity or when things are no longer in his control. Another common theme that leads to both characters fatal demise is their life of abandonment. Joe Keller faced abandonment from his sons Chris and Larry. Chris stood by Joe until he figured out Joe’s lies and mishandling of his business. Joe caused the death of twenty-one other soldiers to Chris and Joe could not be forgiven. Chris abandoned him and was even willing to let Joe rot in prison for the rest of his life. Larry, although now deceased, also abandoned Joe. After hearing news that Joe’s business was responsible for the deaths of his comrades in the Air Force, Larry decided to take his own life because he could not bear the fact that his father had done such a terrible thing. Chris read Larry’s suicide note to his father and this ultimately lead to Joe finally succumbing to all the pressure around him and forced him to end his life. Joe’s mistakes led to those around him abandoning him in the end, even though he did everything in his power to keep his loved ones surrounding him. Willy Loman’s whole life was masked by abandonment. Willy grew up without ever really knowing his father, his brother and role model could care less if Willy were to rot in Hell, and most importantly to him, his sons seem to be embarrassed by him and refuse to stand by him through all of his troubles. Also his boss, Howard, fires Willy when Willy is no longer of use to him and can no longer contribute positively towards the sales company. When at the restaurant, Willy’s son Happy goes as far as to say that Willy is not his father when trying to â€Å"pick up† a bunch of girls to later sleep with. Biff abandon’s Willy in the sense that Willy is trying to escape reality and that Willy is not extraordinary, but merely ordinary. Willy, with all his loved ones no longer standing by his side, decides to end his life and make one final attempt at fulfilling the American Dream by collecting life insurance to help support Biff start up a business that Biff is unwilling to succeed in. Both Joe Keller and Willy Loman were both the typical, hard working Americans. Unfortunately for them, they both contracted horrific tragic flaws which the common person can relate to. Their incapability to properly perceive reality, their misinterpretation of the American Dream, and the constant abandonment they had encountered ultimately led to their own demise.

Sompetition play in people’s daily life Essay

What part does competition play in people’s daily life? Do we put too much emphasis on competition? Are we more affected by its positive models or its less-desirable attributes? Does our economic system rely too heavily on winners and losers, or does the competitive marketplace spur new ideas and efficiencies? Now, I have a challenge for you. Think of one aspect of life that does not include competition. Do you find it hard to complete this task? If yes, why? This is because each day, in any number of ways, we are engaged in competition. Competition exists when there is a scarcity of a desired outcome. Thus, you may wonder, what part does competition play in our daily’s life? Competition makes people to improve themselves every day. Without competition, a lot of people will consider themselves the best in their majors. Though such feeling of confidence is important, it inevitably limits their intentions to develop the knowledge and technique. The appearance of another s pecialist will challenge the importance of the colleague in the same group and encourage him to learn more and do more. A good example is in an orchestra, if there is only one person who is good at playing violin, he may think himself the best and seldom consider improving his skill. Now a new player who is more talented and had achieved higher grade in violin comes into the same orchestra. The former player must face the fact that he is not the best there and needs to learn more and work more to keep up with new skill while the later one will keep practising so that he will always be better than the first musician. This in turn, motivates other players and thus higher the standard of the orchestra. Besides that, competition helps people to learn. It makes us strive for better. When there is a competition, we tend to give our best in urge to win. Even if we lose, we have learnt something.  We learnt from our failure and mistakes For example, in school, students work hard to overcome other people to be the top scholar in the school. If they did not do well in their tests, they will know what are their weaknesses and thus learn more so that they cam improve that. Without competition, students would be lazy and become incompetent. This is because competition is a motivational factor for a person to excel in any field. If there is no competition, students may not study to score good marks since there is no ranking. Moreover, competition builds teamwork. By working as a group to achieve something, we need to work effectively with other people. This in turn, improves our communication skills, socialising  skills and all round ability to work with other people. Therefore, competition makes us learn new things constantly. Furthermore, competition makes the manufactures invent better products which benefit the country and people. With the development of communication and transportation, merchandize can be easily tr ansported from one country to another country, as well as new technique can be easily learned from one region to another region. International competitions in a lot of fields appear. With a lot of brands of the same kind of commodity, customers always prefer the brand with better quality and cheap price. Therefore international competition makes the manufactures develop this kind of merchandize with the good quality and appropriate price using the better technique. As a result, the newest product with better quality and reasonable price improves the quality of people’s daily life and increase the popularity of the country as many people will know the newest product which can improve the quality of their lives is made by this country. If the country has high popularity, the people living in that country will have a better life. This is because more tourists will know and want to visit that country and thus generates income of the country. The country will then develop infrastr uctures which benefit its people. In conclusion, competition makes people to learn and improve and improve their standard of lives.

Greenhouse Effect and Global Warming Essay Example | Topics and Well Written Essays - 750 words

Greenhouse Effect and Global Warming - Essay Example Some of the radiation is altered by the ozone layer, which inhibits ultraviolet radiation from passing directly to the surface to the earth. Much of the radiation that makes it to earth is absorbed and stored as heat in oceans and other large bodies of water. Radiation that strikes portions of the earth with a high albedo, such as solar ice caps and glaciers is reradiated back out into space. In fact, ultimately, the vast majority of solar radiation that enters the atmosphere is destined to be reradiated back into space. But a small percentage of that radiation gets trapped in the atmosphere as it tries to bounce back into space. Certain gasses, such as carbon dioxide and methane act to trap the radiation, causing the atmosphere to retain the radiation as heat. This warming of the earth’s atmosphere as a result of trapped radiation is called The Greenhouse Effect. Gasses such as carbon dioxide and methane are called greenhouse gases, due to their tendency to trap radiation, wh ich causes the atmosphere to stay warm. Without The Greenhouse Effect, life on earth would be very different and impossible for humans. The Greenhouse Effect is directly related to the phenomenon known as Global Warming or Global Climate Change. The earth’s atmosphere is constantly changing. ... Humans are the first species in the history of earth to burn massive amounts of fossil fuels such as coal, oil and natural gas. Burning these fuels puts carbon dioxide into the atmosphere. In recent years, the average global temperature has risen dramatically. Changes in global temperature usually happen very gradually, so many people are concerned that a rapid change in temperature will lead to destructive weather patterns, crop failures, increased spread of disease and insect pests (Roberts, 1994). Many scientists feel that this will lead to extinction on a mass scale and major disruptions to human activities. The continued introduction of greenhouse gasses such as carbon dioxide and methane that results from agricultural, manufacturing and transportation activities will surely result in a warmer global climate and stress on nearly all natural systems that sustain life on our planet. There are courses of action that can be taken to reduce or even reverse the warming trend that eart h is now experiencing. One of the most immediate things we can to is to reduce the amount of greenhouse gasses we are putting into the atmosphere. Much of this comes from the transportation we use every day. Cars burn gasoline, which greatly contributes to the amount of carbon dioxide in the atmosphere. Driving less, or not at all, is one way we can slow global warming. Many people are living in communities that give them easy access to public transportation and to workplaces. More civil planners are providing spaces for walking paths and bicycle lanes in their plans. This means people have carbon free ways to get to work. Using alternative fuels and increasing fuel efficiency in cars is another way to prevent

Integration of the strategy components in achieving Broadway cafs goal Essay

Integration of the strategy components in achieving Broadway cafs goal - Essay Example This means that if the venture has a negative value of the returns or profitability, it is too risky or not profitable, and, the company should reconsider investing in the venture. Broadway Cafe has a rich history in the restaurant business. With modern technological development, the Business has to acquire a niche with the intent of competitively edging out its competitors in the business. IT strategies coupled with appropriate ethic codes would not only protect the older customer base but also introduce the new generation of internet accessible customers. The system also factors in the need to show employers that are not only IT compliant but also customer and environmental friendly. â€Å"Integration of the strategy components in achieving Broadway cafes goal† The Combined use of e-Business, employee ethics together with consumer confidence will provide synergy required in the management and daily operation of the Broadway cafe. This synergy provides a simplified and summar ized vision of the business. With the ventures primary customer base being the MSU students, (an IT compliant public) an e-Business would be more attractive to them. Broadway Cafe expects to acquire a facebook and twitter account as well as other social media sites to seek membership from this population as a way of expanding its customer base. This membership would raise home deliveries, online booking, gift vouchers, and other niceties to pull them. With the additional setting up of a website, it would be simple to reach more customers through advertisements. A broadband service would also be available to ensure that customers comprise time to enjoy their meals plus a moment to surf the Internet. This strategy aims at attracting and retaining clientele that are time conscious, Internet responsive, and also the holidaymakers who prefer their orders delivered to their localities (Amor 207). Eco-friendly clients would also have the opportunity to meet e-tickets and receipts while the business would cut down the costs of purchasing pare receipts. The development of updated customer friendly employee ethics would be manifest. This will ensure that the employees have not only real working conditions but also customer ethics that can attract and retain customers. Most of the other competitors fail to initiate established employee ethics and this situational strategy hopes to capitalize on this tool as a sense of outplaying the other competitors in the business. Furthermore, customer security would equally become crucial. Customers are currently conscious about their safety especially within populated areas such as eateries and other social places. This is as the result of terrorist threats, cyber crimes, and social safety concerns. Broadway cafe hopes to initiate work ethics codes, consumer welfare and employee protection. With the introduction of the Biometric system, customers would be required to provide individual information. It is fundamental to ascertain tha t the management and utilization of such information would be achievable through careful process. The customers will recoup their biodata at will to build their dependence on the business. The Estimated Returns The business expects to source for money in order to achieve these strategies. The financing classification that is most suitable incorporates loans. The company has sourced for a web developer and a forensic officer who are to start work quickly and continue through by the end of the coming week. The estimated costs amount to $ 5,000,

Narrative of the Life of Frederick Douglass Essay

Narrative of the Life of Frederick Douglass - Essay Example In the opening sentences of his narrative, Douglass stated the fact that slave owners thought of slaves as animals (Douglass, 47). It was not just the slave owners who treated their slaves as animals but the slaves themselves also had the perception about themselves. The access to reading opened a new world for Douglass and casted a new light on the world he was already living. The dawning of self-consciousness was the outcome of the acquisition of reading skills, which made him capable to think independently. He also stated that learning to read was a curse rather than a blessing because after gaining knowledge he was able to see his miserable condition with no remedy to get out of it (Douglass, 84). Douglass occasional regrets regarding his wretched condition were due to the knowledge that self-education afforded him and was the main source to change his status from a slave. The ability to read and write was important in the eyes of Douglass because it was through this ability he w as able to describe his story in his own words and refuted the common misconception that slaves were not capable enough to communicate through the standard conventions of American literature. The ability to fully understand his environment and comprehend the hopelessness of the situation faced by him and other slaves was only because of the literacy which was the greatest tool to work for the freedom of slaves. This revolutionary incident of Douglass was the turning point in his career as a slave which revived a wave of manhood in his heart (Douglass, 113). There are no illusions that education plays a key role in setting slaves free because it equips them with the skills and knowledge to improve their lives. It helps in articulating the injustice caused by the slavery and awakens the consciousness to fight against abolition. In case of Frederick Douglass, he was able to reveal the strategy of his master, Hugh Auld, about how he used to manage to keep blacks as slaves and by which b lacks would be able to free themselves. This quote from his narration clearly depicts the importance of learning: â€Å"If you teach that nigger how to read, there would be no keeping him. It would forever unfit him to be a slave. He would at once become unmanageable, and of no value to his master† (Douglass, 49). These ironic words were delivered to the Mistress, wife of Auld, who taught Douglass how to read and was strictly forbidden because they believed that education ruins slaves. The transformation of a kind-hearted woman to a harsh mistress made him realize that the institution of slavery has a major effect on well-intentioned people as well (Douglass, 82). This means that illiteracy and ignorance were the most important elements in the subjugation of slaves. The desire to gain more knowledge was not only a constant battle for Douglass as it was unlawful to teach a slave to read and had to be a secretive process (Douglass, 20). Douglas further said that his mistress ga ve him the start by teaching the alphabets and nothing was so powerful to prevent him from learning (Douglass, 81). The harsh attitude of mistress and vigilance to stop Douglass from seeking knowledge by many means made him clear that an educated slave is a dangerous notion for the masters. It can be noticed that when it comes to education, masters and slaves are inherently opposite to each other. The thing that changed the whole life

Australian Government Intervenes in the Economy Essay

Australian Government Intervenes in the Economy - Essay Example Aside from market failures, the government also intervenes to achieve equality through the reallocation of resources and redistribution of income (Stiglitz, 2002). This last impetus for the government to interfere in the market economy is the focus of this paper. We will take a particular look at the Australian government and its various ways of intervening in the market to improve its outcomes: with a specific focus on reallocation of resources and redistribution of income. A study of the Australian National University's Centre for Economic Policy Research highlighted the income inequality in Australia. "The study revealed that "taken overall, the 60 years from 1921 were apparently a period of major decline" in the share of income going to the wealthiest taxpayers" (Michaels, 2006). By 1980, the share of the top 1% fell from 10% of the total income to 5%, the 0.5% fell from around 9% to 2.95% and the top 0.1% was cut down from 4% to approximately 1% (Michaels, 2006). ... er the same period and the share of the top 0.1 percent, which had fallen to approximately 1 percent of the total in the 1980s, more than doubled to over 2 percent by the end of the 1990s" (Michaels, 2006). The introduction of the imputation system "in which part of corporation tax paid is treated as a pre-payment of personal income tax" has exacerbated the inequality (Michaels, 2006). Early Redistribution Activities Australia government depended on three redistribution methods: "the progressivity of the taxation system; the distribution of government cash payments; and the absolute level of government in-kind and cash payments" (Robinson, 2007). "From 1910 to 1940 per capita levels current of Australian social expenditure in 1911 prices rose 208% substantially more than Butlin's estimate for GDP growth in 1911-39 of 48%. The introduction of aged pensions, the maternity bonus and repatriation services saw the Commonwealth take a leading position in overall social expenditure, in particular cash payments to individuals, but the states remained dominant in the delivery of in-kind services, particularly education and health and NSW from 1927 introduced widows' pensions and child endowment" (Robinson, 2007) Australian government has given much in terms of pension and reparation. Excluding the NSW widow pensions, pension and reparation became the government's responsibility in which the distribution is "allocated per capita among the census category of Pensioners as identified in the census" (Robinson, 2007). There were also in-kind government services which is composed mainly of health and education and administered by the state in proportion to their population (Robinson, 2007). The government also resported to cash payments, although it covered only a small

Prescription Addition Essay Example | Topics and Well Written Essays - 1750 words

Prescription Addition - Essay Example This paper shall examine the various reasons for prescription addition of the eye of an individual. We will examine various common ailments and the reasons due to which these ailments cause a prescription addition. The areas which will be studied in this section are Presbyopia, Anisometropia, squints, the various debilitating effects of diabetes mellitus and juvenile stress myopia. These issues will be studied with respect to their relevance in prescription addition. The other major issue which will be studied is the difficulties in dispensing eye prescriptions. This issue is an often neglected issue, but it has a big effect on the patient as it is the patient who is eventually denied suitable eye care. The dispensing issues which will be examined are aphakic prescriptions, iseikonic lenses, pediatric dispensing, low vision aids and protective spectacles. These dispensing issues will be examined from the patient's viewpoint. As mentioned earlier there are numerous causes due to which prescription addition occurs. The most common is Presbyopia, which is caused due to increased age. The main cause of presbyopia is the reduced suppleness of the lens in the human eye. This suppleness is required to focus the objects near the eye. The Ciliary muscle which helps the eye to focus becomes less efficient. The lens loose their ability to alter their focusing power, the capsule which contains the lens in the eye loses its suppleness. The combination of these two factors results in a decrease in the ability to accommodate (reduced accommodation) (Woodruff 2001).This results in progressive prescription addition with the passage of time. Anisometropia Anisometropia is caused due to the differences in the dioptric values between both eyes of a single person. This is generally caused either due to refractive surgery causing a difference in the ability of both eyes. Other reasons are overcorrections of myopic and hyperopic patients. Lastly, Anisometropia is also caused, if one eye is significantly more astigmatic than the other. Irregular astigmatism can cause an imbalance in the refractive power of both the eyes (Woodruff 2001). Prescription addition due to Anisometropia are caused primarily because of either surgery causing a difference in the refractive power between either eyes or the overcorrections of myopic and hyperopic patients. Squint A squint refers to a state where the eyes are not aligned in the same direction Squints are caused by many reasons and occur more in children. As we are focusing on prescription additions, squints especially those that arise from hypermetropia (long sightedness) are treated with the relevant prescription addition. Then the child will be assessed for the decrease of the degree squint and the child's prescription will be changed accordingly. There are various reasons for the occurrence of squints and consequent prescription addition (for the correction of the squint) amongst children. Illnesses like viral fever, measles, and meningitis are known to cause squints. Injury to the nerves attached to the eye muscles can also cause squint.

Vocal nodules Essay Example | Topics and Well Written Essays - 500 words

Vocal nodules - Essay Example However in order to fully appreciate the mechanism involved in this process an understanding of speech mechanism with respect to the role of vocal fold nodules is required. This is discussed below; The larynx or the voice box has a twin infolding of mucous membranes (vocal folds) stretched across the larynx. During speech or phonation, the air flow (originating from the lungs) is modulated by these membrane vibrations. Increased air flow/air pressure in the lungs causes the folds to open and once the pressure recedes after the air flows out the fold close again. These folds vibrate when closed due to internal air pressure. (Cumming 2005) In effect, the loudness of speech or what is best termed as the pitch of the voice is determined by resonance frequency of the vocal folds and is measured in hertz. Fundamental frequency of vocal fold vibration correlates with changes in vocal fold tension and subglottal pressure and hence vocal fold mass, stiffness, and viscosityis the main predictor of the pitch of the voice (Hirano 1987). Vibrations of the vocal folds that are too forceful or prolonged result in vascular congestion. If persistent they will eventually result in hyalinization of superficial lamina propria and eventually this is likely to lead to the formation of nodules.

Litmus Milk Procedural Essay Example for Free

Litmus Milk Procedural Essay Litmus milk is a complex medium that can potentially distinguish many species of bacteria. Litmus milk has several components that can be metabolized: lactose (milk sugar); casein (milk protein); and litmus (a pH indicator). If lactose is fermented, the solution should turn pink. If gas is produced during fermentation, you may be able to see bubbles or cracks in the milky medium. If lactose is not fermented and proteins are metabolized instead, the solution will become alkaline and turn blue in color. If casein is digested, the milk will coagulate to form a curd (a solid). Casein may be metabolized all the way down to individual amino acids. This process, called peptonization, results in a clear (not milky) liquid that is usually brown in color. Finally, the litmus may be reduced and become colorless. The culture will then look milk white. Materials: 1. Litmus Milk Broth 2. Bunsen Burner 3. Inoculation Loop 4. Nutrient slant 5. Goggles 6. Lab Coat 7. Incubator Procedure: 1. Get an Inoculation loop and sterilize it using the Bunsen burner. 2. Take bacteria from your nutrient slant on inoculation loop 3. Inoculate a litmus milk tube with the bacteria. 4. Incubate for 72 hours; observe results every 24 hours for 3 days.

Role of a Coach in Athlete Development

Role of a Coach in Athlete Development Jarod Pender The famous basketball coach of UCLA that set the record for most championships, John Wooden once said I think the teaching profession contributes more to the future of our society than any other single profession. Coaches play an important role in the development of young athletes that carries on with them as the becoming adults. The most important factor in an athletes development is how they are treated by the coach. As we will see coaching is an important building point in the lives of young athletes and this is a main factor in how they develop into adults. From being a parent like mentor to these athletes and showing them important skills it is important that coaches take good care of their athletes. An important point made by John Wooden is that Young people need models, not critics. John wooden was a pioneer in coaching and clearly his methods worked because he had an astounding record and many titles to his name from his success at the UCLA. He broke the record of winning 7 c hampionships in a row and won ten in twelve years. His coaching standards have been changed from modern times but he set a winning standard in coaching, and many of these ideals in the following were his ideals. From many of the points that will be brought up in this paper you will be able to distinguish the difference from acceptable coaching to poor coaching. Firstly, Coaches have an important part in the development of the physical growth of young athletes. Coaches have a strong say in how much athletes exercise and stay in shape. Many coaches have their athletes highly active in lifting weights or conditioning. Some coaches have their athletes work too hard and they put their bodies at risk for injury that they have to continue in fear of losing playing time. Many athletes do not realize that they can speak up about the pain and that they think they have no say in the matter, but they do its their body. If an athlete is too scared to speak up about an injury then the coach is putting too much pressure on the athlete and is putting them at high risk for injury. An athlete has a right to keep his own body safe and healthy, but if the coach only wants to win then they might feel pushed to keep playing through the pain. As we look throughout this paper we will see this is only one of many bad characteristics of a bad coach and this alone ca n not only risk the athletes health, but it can ruin the ability for the athlete to trust people close to them. It is common in basketball for coaches to run their athletes until they puke or just about. When coaches do this they put their athletes in danger of exhaustion, heat stroke, and possible sicknesses. Coaches need to understand where to draw a line between improvement and damage. It is the same way for lifting weights if an athlete is doing too much they can put themselves at risk. Also coaches of all sports need to realize that they need safe, but aggressive drills to keep their athletes safe and allow them to last the whole season without excessive injuries. Secondly, Coaches have an important part in the development of the mental growth of young athletes. Coaches can play many roles for athletes in life such as: father or mother figures, mentors, a boss, or friend. Based on this we can see how the coach will develop the athletes mental growth. If the athlete thinks of the coach as a father or mother figure the athlete probably is a positive, but strong influence on the athlete pushing them to succeed allowing them just enough pressure to grow, but not letting them break. If the coach is viewed as a boss the athlete probably does not expect much from the coach besides coaching and improving as an athlete, they will not look for support or encourage from this coach. If the coach is viewed as a friend, then the athlete just wants encourage from the coach and will not likely want this coach putting lots of pressure on them. As athletes get older they can handle more information, stress, and other things that come with being an athlete, but certain coaches control when they grow into this. Many athletes experience a coach when they are young that is considered a bad coach, one who puts winning above his players, this grows into the player over the years. What many players do not realize is maybe that middle school coach or even younger set them up for how they handle pressure in the future from a development in their young years. With this mental growth can come the ability to play mind games with the athletes which indeed can cause damage to the athlete in their ability to trust people long term without worries of alternative motives? Thirdly, Coaches have an important part in the development of the spiritual growth of young athletes. Many athletes in Christian demographics look to their coach for guidance as they can relate to being a Christian athlete, but this can get tricky. Depending on the coach whether or not they are Christian can affect the role they play on the athlete. Obviously if he or she does not give good spiritual advice because he or she is not a faith oriented coach it is going to cloud the judgment of the athlete. Another issue is if the coach is a Christian and he or she pushes Christian ideals, but he or she does not follow them when he or she coaches his or her athletes. Many people would agree with the statement do not talk the talk, if you can not walk the walk because if you tell your students you need to be encouraging as a person to be a Christian, but are a jerk coach then you set a horrible example. Like many things even if it is not spiritual, if you can not follow your own rules you set for your players then you should not force your athletes to follow them. In a world where hypocrisy is flourishing it makes it hard to set a standard and follow it, but if you can not absolutely follow the rules you set for your athletes maybe you need to seek help so you can fix this problem you have. At these youth and teen ages many kids are looking for a spiritual mentor and if someone ruins this for them at a young age then it might ruin how they grow up in the faith, which could force them from it all together. We all need someone to guide our way if we do not then we can fall prey to the random evils around us everywhere. Most kids if they do not have good role models in cities where crime can be a problem they can get involved with the wrong kids or crowd and lead a poor lifestyle. When these kids follow these poor lifestyle choices it can lead to drugs, abuse, gang activity, jail time, or just a poor life because they did not take things seriously and they let it go to waste. Fourthly, Coaches have an important part in the development of young athletes self-esteem. Many studies show that if a child is supported as a child that he or her will have a better chance of being confident growing up. It is the same for children who are constantly put down they will have confidence issues when they grow up. While yes some kids can be supported still growing up not confident in themselves or the complete opposite make an adult of themselves after being left alone. While these studies are evident I think there is one thing that can link many of these cases together, many people in their lives attempt to play at least one sport. While many people play on sport in their life it is often they quit after one sport because they are discouraged and thus do not feel like they want to be bad at something. Many of these people lacked one thing in their experiences: a good coach to encourage them to keep trying, motivating parents, or the drive to succeed. While you do not al l three to be a good athlete have a coach that encourages can make up for the lack of the other too. While not everyone can have supportive parents it is important that coaches can play a little bit of that parenting role by being there for the athlete and supporting them. While there may be a lack of studies proving that coaches play such a high role in the development of athletes I really believe in the next ten years it will be clear and evident how coaching effects these athletes long term. When we see these effects we will be able to identify who had good, moralistic coaches and those who had the bad coaches through their development. While yes there will be variations and deviations from the pattern like the successful business man or woman, or whatever genders will exist in ten years, who pushed through the abuse and degradation of his skills, attitude, or himself from his high school coach to use it as a motivation to succeed and be better. Fifthly, Coaches have an important part in the development of how young athletes handle pressure. If young athletes are giving large amounts of pressure this can over load how they handle things, while it may prepare them for the future you should never put too much pressure on a youth athlete. If you put too much pressure on a young athlete he or she might quit the sport, become discourage, or just easily become frustrated. Pressure management is an important role in coaching youth as they are the future of our sports and world. Growing up playing sports I can agree when a coach puts too much pressure on an athlete a couple of things may happen: one the athlete overcomes the pressure pleasing the coach, the athlete does an average job not over impressing the coach, or the kid completely crumbles under the pressure. If the athlete completely crumbles under the pressure it could leave a lasting impression on the athlete mentally and emotionally, which could stay with them way until th ey are a grown adult making big decisions. If an athlete can consistently succeed under pressure the coach will obviously put more focus and effort into coaching this athlete over others because he or she will help the team more. Most athletes fall into the middle category they complete the task, but it is not as impressive and does not leave wow factor. These athletes are going to either grow into people who can take pressure more than before, will stay as mediocre, or some will fall into the problem of crumbling under pressure. It is important while these young athletes are growing to realize that how much pressure we put on them can affect them for the rest of their lives, but if we take it for granted we can let our goals come before the development of these young athletes we are trying to grow. While pressure can come from good or bad coaching it is how these coaches handle the pressure they give and how they react to the outcome of the athletes response to pressure. Some coach es may put pressure on the athletes to try out a starting spot for multiple athletes, which develops competition which helps develop aggressiveness for fighting for the spot. On the opposite spectrum a coach could put too much pressure on an athlete and then freak out on the athlete when he or she is not good enough for the coachs expectations. Many criminals and addicts have something in common, they were missing a role model in life. Many of these people realize that your parents can not always be your role model, that it where coaches come into play. Many sources believe that the longer that athletes stay in sports the more likely they are to stay out of trouble, which is due to the fact in sports kids have to have decent grades, stay drug free and stay out of trouble in school to stay eligible for their sport. Even to the fact that people admit if they would have stayed in sports they would not have gotten hooked on drugs, joined a gang, or even just kept on a better path. In my life I have personally seen friends who have stopped playing sports and their lives really took a turn for the worst. Luckily I have not had any friends fall into drug addiction, but while I have not experienced this there can be 15 people in Adrian alone who have seen or been in this exact situation. Sixthly, the development of young athletes can be drastically changed by the effects of bad coaching. While many coaches work hard to improve the lives of the many young athletes that come through their programs, it does not matter how many good coaches there are because there will always be bad coaches. What is considered a bad coach you may ask? Well if you do more than one of the following you may be a bad coach: yell at players constantly, do not encourage them, pressure them into playing through injuries, lack patience, are hypocritical in your coaching, play favorites, play mind games, force them to keep what happens in practice a secret, coach with a negative attitude, say your team is the worst you have coached, degrade players. If you take part in one or more of these activities in practices, games, workouts, or any other setting where you are the coach then you may be a bad coach. While many coaches who are completely awful coaches may not know they are a bad coach, there a re a few who do realize what they do. If you realize you bully your athletes you need to either change or quit, because you are only helping yourself with the salary if all you do is breakdown your athletes every day in and out. These tendencies can easily be passed down if you ingrain it into the minds of your athletes. One of the main problems is that many coaches who partake in these problems have good teams or programs so while they are awful coaches, they still get wins which makes them look unlikely to get fired. It can seem impossible for some coaches who bully their athletes who coach in a good program to get fired but as soon as they have a bad season they have good chances of getting fired. With these chances sometimes being slim it can be difficult for parents to deal with these hard to work with, devil like beings, the best thing you can do is try and encourage your athlete and try and make sure to keep the coach in check as much as possible. While you may be tempted to talk to the athletic director sometimes the athletic director is very bias towards protecting who he or she has hired and will not do anything against the coach even if he or she is truly wrong which happens commonly at schools all crossed the country. Seventhly, the development of young athletes can be drastically improved by the effects of good coaching. While it might be easier said than done if you just say be the opposite of the last paragraph, it is not that simple. To be a good coach you have to have a love for three things: God, your athletes, and the programs development. Having a strong spiritual structure can help make your coaching easier because following the bibles teaching helps your be more encouraging. Also none of the things that make a bad coach are good in the bible so it is easy to stay on track. The other step of having a love for your athletes. To be a good coach you need to truly love your athletes, not the jerry Sandusky type of love, but the type of love that you view the athletes as sons or daughters. If you view the athletes in your programs like sons and daughters it makes it much easier to make the right decisions for these young athletes, which in the long run will make you a better coach then before. If you love someone like a daughter or son you will treat them with respect, tough love, and will want the best for them. Lastly you need to have a love for the program. A good coach just does not care about his current team, but he or she cares about the future of the program. Good coaches constantly have camps for the future of the program so they can develop their future teams better. If the coach only cares about the current team and not the future of their program they may lose young athletes to other programs or schools simply because they payed more attention to the young athletes. This has become a growing trend in many programs in the past years as they need the future to succeed in weaker years. Many good coaches use this technique to build solid programs for many years because if a varsity coach works with elementary kids they will be more likely to stay and possibly bring friends to the school as well. Also if a younger athlete has better skills to improve to future tea ms the more likely the coach will keep his job if he or she has multiple years off success. The problem with this is in year of skill and ability drought he or she may decide to play under classmen more than upper classmen to look for the future of his program, because he or she can make up for a bad year this year if he or she has a great season the following year. In conclusion, from all the papers and information I have read over the past couple of weeks it is clear and obviously how to define a good, moralistic person who is a coach. A coach is not defined by the wins he or she gets on the court, field, or arena; but by the athletes he or she develops while they are in his or her program. From the many parts of coaching we hit in this paper many of them seem to boil down to who the coach is morally, if he or she are morally a bad person they will not most likely be a good coach. From building these athletes in to the person they will develop in to as a man or woman, these coaches lay the building blocks for these boys and girls. If they lay the foundation poorly either it will affect the structure immediately and someone will have to fix it or it will build up until it all collapses later in life. It is very important that when they men and women are given the opportunity to lay the foundation of the lives of our boys and girls that they mak e the right, moralistic decisions that will make them grow in amazing men and women. It is important if you are going to build a house to put in a correct, secure foundation; because if you do not then the possibility of the house being damaged later on is more of a higher possibility. That is why when you go to build a house or a building you make sure you have good, competent builder to secure a foundation that will last for generations. In this metaphor the coach being the builder and the boys and girls being the foundation of a house really works well as it shows the possibilities of where the coaching will take the athletes in their futures. When we look for someone to coach our young boys and girls we should take more care to look into the person to verify they will the type of person to make our boys and girls in to the best kids they can be and if they become good athletes too then that is the bonus. We live in the era of people looking for a coach who is going to get wins, but this is a faulty ideal because if the coach mistreats the athletes or does not grow them then you can be doing more harm than good. We need to be more focused on a coach that develops hard work through encouragement, not through punishment. I do think sometimes punishment is needed, but some coaches use punishment as a fear tactic to push athletes in the wrong way. This idea of coaching definitely will cause some athletes to perform, but others definitely will not respond well to this coaching style. As we continue through this new generation of athletes I think more data will come out after seeing the effects of coaching on the last few generations of athletes, at this point we will find out just what the poor coaches caused and what the good coaches created out of these boys and girls.

Deep Sea Fishing :: Personal Narrative Essays

Deep Sea Fishing Wow! I love going deep sea fishing on our boat. I was excited when my dad had asked me if I wanted to go this weekend. We departed that Saturday morning after almost a week of sheer anticipation, our destination, Port Canaveral, home of of some of the best fishing on the east coast of Florida. The sea is a very dangerous place when riled by a storm, even a mild one, so we always made sure the day would be at least close to perfect before we ventured out into the blue darkness of the open sea. My dad and I had seen the destruction careless boaters could get themselves into, and we did our best to avoid it. That Saturday, though, looked as if it were a perfect offshore fishing day. The sky was clear as glass, with a couple straggling cirrus clouds, but nothing worth paying attention to, and above that, the fish were supposedly hitting offshore. All-in-all, the long awaited perfect fishing day had come, at least in our minds it had. In the meantime, my dad backed the boat into the salty murky water as I got the boat ready for our day long journey. I set the navigation system to a favorite fishing spot of ours which was about twenty-five miles out called the Pelican Flats. We headed out on the gently, quiet, rolling blue monster's back as our twenty-two foot vessel handled the one to two foot ocean swells with sheer ease. Finally, after an hour long haul, and fifteen fishing minutes later, we ran into our first sign of action. "Fish on starboard!!" screamed my younger brother. "Fish on stern, grab 'em!", bellowed by dad from the steering wheel. Instinctly, my brother and I had quickly grabbed the poles as the line screamed off and the tips bent almost to the water. Soon enough, both of us had fish on, very large fish from the feel. About half an hour of sweat and a good workout, we finally got the fish to give up their fight for life. That was the first time we had ever encountered a double hook-up, which happens when two fish of a considerable size are hooked simultaneously, and it happened in less than fifteen minutes. We ended up fishing for about four more hours and landed an incredible number of large fish, and we wanted more. The three of us scanned the surface for more action, and found nothing of interest but what looked like a storm cloud moving towards us at an unknown velocity about

Nigerian Government: From Military Rule to Democratically Elected Governance. :: Essays Papers

Nigerian Government: From Military Rule to Democratically Elected Governance. Nigeria’s government has recently gone under a dramatic change. For my paper I decided to write on the topic of Nigerian government. When I interviewed a student, named Arit, from Nigeria, she told me how her country was formerly under military rule and had recently changed to a democratically elected government. Arit believes this is a good change for the country and it will help fix the destruction military rule left behind and pull Nigeria out of the dark. Military Rule Background The people of Nigeria suffered under the control of military rule and are now experiencing the recent change to democratically elected governance. One of the greatest problems in examining the background to military rule in Nigeria is figuring out when the seeds of the takeover and the tragedy of civil war were sown (Oyediran). When military rule first started in Nigeria, it was seen as a rescue operation and was not expected to last long. However, this was not the outcome. Nigeria gained independence in 1960 and out of the forty-three years post independence, the military ruled for twenty-nine years (Igbuzor). In January of 1966, the first military intervention occurred. Structure After the military gained political power the next thing they do is ‘abolish’ all political parties. The reason for this action is because the military sees such organizations as instruments of disunity, agents of strife, discord, and corruption. They also believe these organizations create the conditions that warrant the military intervening (Dudley 85). Nigeria’s military ruled government included: (1) Increased influence by political and military leaders of minority tribes (2) replacement of political party leaders by the military as general policy makers; (3) increased policy-making role for permanent secretaries and top echelons of civil service; and (4) replacement of the four powerful regions by twelve â€Å"states† (Imer 69). Problems However, abolishing the political parties does not destroy the political conflict. In fact, the strife is not eliminated but a vacuum is made between the leaders and the led (Dudley 86). Under military rule, the people of Nigeria were overwhelmed with corruption, fraud, embezzlement, and political instability (Johnson). These problems were reoccurring throughout the twenty-one years of military rule. First Elections The 1999 Constitution provided for a democratically elected government in section seven of the constitution (Igbuzor). February 28, 1999, Nigerians voted in a presidential election to put an end to military rule.

Attenuation Effects on Data Transmitted through Cable :: essays research papers

Attenuation Effects on Data Transmitted through Cable Abstract Attenuation refers to any reduction in the strength of a signal. Attenuation occurs with digital or analog signals. Attenuation is the end result of signals being transmitted extended distances. Attenuation is usually expressed in units called decibels (dBs). The cable type will determine at what point along the length of the cable signal degradation occurs. Repeaters can be inserted along the length of the cable to boost the signal strength which increases the maximum attainable range of data transmitted though the cable. Attenuation Effects on Data Transmitted through Cable The majority of attenuation in Coax cable comes from resistive losses in the cable's metallic conductors. Temperature also has effects the resistivity of the conducting surface. Resistivity is a "bulk property of material describing how well that material inhibits current flow. This is slightly different from resistance, which is not a physical property. If one considers current flowing through a unit cube of material (say, a solid metal cube that measures 1 meter on each side), resistivity is defined as the voltage measured across the unit cube length (V/m) divided by the current flowing through the unit cube's cross sectional area (I/m2). This results in units of Ohm m2/m or Ohm-m." [University of British Columbia Geophysical Inversion Facility] Temperature affects the movement of electrons in the material. When a signal voltage is passed through a wire the electrons collides with the atoms in the material. If more atoms are allowed collide with electrons, the greater the frictional resistance, which affects the cable ability to conduct (allow data to pass through the cable). Temperature causes the atoms with in the material to move. Increasing the temperature causes the atoms to â€Å"jiggle† which causes frequent collations with electrons. The opposite is true when the temperature is lowered. Attenuation is a function of the frequency of the signal, and the length and physical structure of the cable itself. Specifically, it depends on: †¢ The diameter of the inner conductor: as the diameter of the conductor increases, attenuation decreases. †¢ The composition of the outer conductor: the more effective the screening action, the lower the attenuation. †¢ The nature of the dielectric: the lower its constant dielectric, the lower the attenuation. Therefore, an expanded dielectric supplies, at any given diameter, values of attenuation lower than a solid dielectric. Since the type of cable, the temperature, and the rate at which data is being passed through the cables are constant, the length of the cable is the only factor that affects the attenuation in the two cables.

Labor Relations

In this paper, unions and labor relations will be defined and their impact on organizations will be elaborated. Also, the impact of changes in employee relations strategies, policies, and practices on organizational performance will be examined. After this, the question â€Å"Are unions still relevant in the U.S.?† will be answered. Furthermore, the campaign, the election, contract negotiations, grievance handling, arbitrations, labor relations, and strikes will be addressed. Labor unions and labor relations Labor unions, which are the watchdogs and negotiators for the American workforce, are a way of collectively bargaining with employers for fair working conditions and fair wages. The craft unions or skilled laborers and industrial unions or laborers in the same industry, regardless of skill are the two types of labor unions that are organized. In the U.S. Groups of highly-trained carpenters, tailors, printers, and weavers in the colonial age, the seed of modern labor unions were the guilds. Guilds, which are economic and social in nature, are associations of persons who are involved in the same craft or business. The workers who members of guilds are banded together so that the quality standards would be maintained and the employers’ hiring of skilled laborers from home would be ensured. In the mid-19th century, there was an increase in the number of new industrial unions which were created for the assertion of workers’ rights. This change in the personality of the American workforce was due to the invention of the steam engine and other industrial advancements. The Knights of Labor, which inaugurated the Labor Day holiday in 1882, was one of the most important industrial unions. In the 1890s, the American Federation of Labor (AFL) was formed. It is composed of the craft unions which include both skilled and unskilled laborers. The federation was formed because its member craft unions were opposed to the composition of the Knights of Labor’s membership. The United Mine Workers and the Danburry Hatters case in 1902 were ones of the early conflicts and strikes included in this period. In the 1930s, when the Great Depression took place, the Congress of Industrial Organizations (CIO) was formed. Many of the members of CIO were the dissidents of the AFL who favors industrial unionism. Workers in the steel, rubber, auto, maritime, glass, and meat packing industries were some of the major constituents of the CIO. In spite of the conflicts during the 30s and 40s, a powerful body known as the AFL-CIO was formed from the merging of the two national organizations in 1955. The National Labor Relations Board (NLRB) is an independent agency of the U.S. government. It was created under the National Labor Relations Act of 1935 or the Wagner Act and was amended by the acts of 1947 or the Taft-Harley Labor Act and 1949 or the Landrum-Griffin Act. The board affirmed the rights of the labor to organize and bargain collectively through representatives they chose or to refrain from such activities. The board which is composed of five members is assisted by 33 regional directors. The members are appointed by the U.S. President with the approval of the Senate for five-year terms. The proper bargaining units are determined, the elections for union representation are conducted, and the charges of unfair labor practices by employers are investigated by the board. Coercion, interference, or restraint in labor’s self-organizational rights is included in the unfair practices (Villanueva Siasoco). A research study revealed that the collaboration of an organization (such as community organizations) and a labor union is an impetus for change. For example, the labor unions and community organizations in Greater Boston, which have worked together in recent years, have achieved remarkable successes. Some of their victories include the passing of a Boston living wage ordinance, an increase in the minimum wage in Massachusetts, improvement in union contracts and in workplace conditions, an earned income tax credit on state income taxes, $6 million state job training program for 1, 500 workers, and a number of progressive tax policies which includes a new tax on capital gains. These significant achievements in Boston are reverberated throughout the country. This is manifested by the continuous formation of alliances by community organizations with the organized labor. Again, these alliances are formed for the purpose of tackling problems that affect the lives of the low-wage workers. The Service Employees International Union, which is known for its successful Justice for Janitors campaigns, is one of the unions that organize low-wage workers. The Hotel Employees and Restaurant Union is also a low wage-workers union. These unions are included in the most vibrant and fastest growing organizations in the country. The collaboration of labor unions and community organizations is really needed for the achievement of long-term goals of economic and social justice. The need for the collaboration is being intensified by the changes in the national economy over the last few decades. One the changes that forces for a collaboration of labor unions and community organizations is the shifting of the economy from higher-paying manufacturing jobs to lower-paying jobs in the service sector. Similarly, the public policy efforts for the promotion of the welfare of working families in general are being broadened by the labor movement. The national AFL-CIO, under the new leadership since 1995, has devoted increased resources to advocate policies. These policies include the universal health care coverage which is intended to benefit all American who are working (not only those who are members of unions) and the raising of the federal minimum wage. One of the impacts of labor unions in policies is the announcement of support of amnesty for undocumented immigrants by the AFL-CIO in February, 2000. In addition, the AFl-CIO also played a major role in organizing, planning, and supporting the Immigrant Workers Freedom Ride of 2003. This ride is a nationwide effort which aims to raise the visibility of the issues of the immigrant workers (Ranghelli 4). On the other hand, the impact of changes on employees is the decrease in the purchase of labor by employers because of the higher wages won by unions. The success in asserting for higher wages and better working conditions also reduced the number of jobs available (Reynolds). Are unions still relevant in the U.S.? The question â€Å"Are unions still relevant in the U.S.?† does not need anymore time to think about. Unions are absolutely relevant in the U.S. Considering the economic situation today, wherein the trend is to shift from higher-paying jobs to lower-paying jobs, to use more machines than labor force, and to employ contractualization, the exploitation of the labor sector becomes more intense. Thus, unions play a vital role in achieving economic and social justice. Considering the opinions raised by Reynolds, it is very shallow to say that the labor unions are the anticompetitive force in the labor markets. It is very inhumane to think of workers as simply inputs that are needed to be purchased in order for a process such as production or manufacturing to materialize. It is in this thinking where the exploitation of the laborers’ rights arises. Regarding campaigns and elections, union officers are elected based on the standards established by the Labor-Management Reporting and Disclosure Act of 1959 (LMRDA). Officers in the local unions are elected through secret balloting. On the other hand, officers of the national and international unions are elected either by secret balloting of the members or by delegates who are chosen by the secret ballot. The election of the officers of the national and international unions is held at least every five years. For the intermediate bodies, the election of officers is held at least every four years and for the local unions, election of officers is held at least every three years. The funds of a union may be used in conducting an election. Also, it is an option for the employers and unions to use their funds in promoting the candidacy of any candidate (http://www.dol.gov/compliance/topics/unions-elections.htm). Collective bargaining refers to the negotiations between an employer and a group of employees. Negotiations are done so that the conditions of employment would be determined. The result of the procedures of the collective bargaining is called collective agreement. Union or other labor organizations represent the employees in bargaining. Federal and state statutory laws, judicial decisions, and administrative agency regulations govern collective bargaining. Arbitration refers to the method of dispute resolution. This method is used as an alternative to litigation. Arbitration is usually used to resolve disputes between employers and employees during a collective bargaining (http://www.law.cornell.edu/wex/index.php/Collective_bargaining#collective_bargaining_and_labor_arbitration:_an_overview). Usually, strike is the last resort taken by workers in addressing their grievances. Holding mass pickets is the most effective way to involve all strikers. Although strikes may mean decrease in wages or dismissal from work, success in such solidarity actions is effectively achieved through picketing the workplaces of the workers (http://libcom.org/organise/guide-to-taking-strike-action). The aforementioned concepts support the answer that unions are still relevant in the U.S. For example, the funds of unions are very vital during an election because may be used to promote the candidacy of a certain candidate who, when elected, must address the concerns not only of the workers but the families in general. Also, it is very significant in addressing the welfare of the people because what labor unions fight for is not just their interests but the interests of the masses. Again, labor union should not be viewed as a hindrance for the economic development. It is not enough to say that a country is developed based on a high gross national product which is achieved through lower cost of production that includes lower wages for the laborers. Higher gross national product which is achieved through exploitations of workers does not mean economic and social justice. Reference Collective bargaining and labor arbitration: an overview.

Essentially, employee relations are centered on the ability to resolve and prevent conflicts that involve either an individual or the teams in the organization which directly affect work situations and performance. Efficient communication ensures that information is passed to the employees in order to allow them understand better the company’s goals and objectives. Most employee relations managers uphold the responsibility of handling grievances, individual code of conduct while in the office, evaluation of employee performance and counseling programs. Sound employee relations are based on participation and effective communication for both the management and the employees. There are various management styles that cover the way employee relations must be conducted in order to achieve the best from the employees. (Selid, 1995) Trade unions are organized groups of employees officially recognized by both the government and their employer that have come together to promote their common interests. Trade unions have a responsibility of ensuring get the value of what they work for. They are directed to provide a communication channel between the employer and the employees. In some cases, In the United States, trade unions are registered by the specific State that it operates from and they are ratified by the federal government. The United States have a national advisory board referred to as Employee Relations Advisory Board (ERAB) that is concerned with formulating national policies which must be adhered to by individual Employee Relations Advisory Organization (ERAO) which every institution including airline companies must have. At least one representative of ERAO is elected to sit at the Employee Relations Advisory Board. In an airline setting for example, their union is responsible for providing the company’s management with suggestions on how to solicit and disseminate information on plans and programs that are designed for employees who will enhance efficiency and effectiveness in the workplace. (Employee Relations Advisory Organization, 2004) There are impact of changes in employee relations strategies, policies, and practices on organizational performance. For example if employees within an organization are represented by a trade union fully recognized by the same organization e.g. the airline company and the government, cooperation between the employer that is airline company and its employees will be enhanced the workplace. Good and sound formulated strategies and policies that relates to labor relations in organization particularly the airline companies will lead to attainment of organizations goals and pursuing the company’s mission statement in the direct path. There are various management styles that cover the way employee relations must be conducted in order to achieve the best from the employees. These management styles are intended to teach employees the following; applicable regulations and policies, bargaining agreements, grievance and appeal rights, and discrimination and protection of whistleblowers. The impact of changes in employee relations has broadened its definition from the initial industrial relations to such aspects as employer-employee relations, personal contracts, workplace environmental safety, and socio-emotional factors. In developed countries like in the U.S and mostly in airline industries, there is a growing trend of harmonization in almost all levels of government mainly because of the government commitment to enhance employee relations programs. (Sparrow and Hilltop, 1994) Trade unions plays a very major role in trying to protect the rights of employees who form there membership and research indicates that they still relevant in the U.S. administration because they have the task of ensuring that employees rights regarding to the workplace are protected. However, due to corruption and other malpractices the effectiveness of these trade unions has been compromised over the last few years. Research indicates that the employers in the U.S. for example employers in the airline industry are reported to be harassing there employees in the pretext that they are giving out instructions to be obeyed in order to achieve the stated organizational goals, a development which does not auger well with trade unions in the U.S. (Delaney and Huselid, 1996) In general, these trade unions has the following roles, labor climate assessment, positive employee relation programs, union campaigns and election objectives, unfair labor practices such as poor wages and unfounded dismissals, dealing with workplace harassment, coordinating and implementing cooperate relations programs, and handling complaint/issue resolution processes in the respective organizations among others. The only problem that normally cause misunderstanding between the trade unions and the companies or government is that the trade unions can organize go slows, strikes, destructions etc when round table solutions to issues fails. This is very hard for a company to control but with negotiations, it can reach an agreement. Trade unions officials are responsible to their members and they are usually elected to office mainly through secret ballots. This implies those vying for any seats have to campaign for votes from the union members. Sometimes some officials use unfair campaign strategies that do not foster fairness and equality among the contenders. Also these trade union officials play a significant role in any country’s general election because they can influence their members on what directions to vote e.g. advising the members to vote out the present government because of some dissatisfaction that they have with it. Trade unions plays an important role contract negotiations; almost everything can be bargained these days and therefore with employee relations through trade unions such issues as awarding contracts, compensations, benefits, and work schedules can be sorted out by discussing them until a solution is achieved. The bargaining approach settles conflicts that arise as a result of contract matters. It also outlines the rules with which the basis of handling specific work agreements is sorted out. Normally, if this approach is well utilized, employee relations are greatly improved. Grievance handling in any organization is very crucial to all organizations and at least every company has some way of dealing with their grievances. In fact, it is considered that a few individuals in a company are so arrogant that they are font of harassing their workmates leading to poor productivity. Companies need to develop a grievance handling procedure that will ensure that conflicts are eliminated in the organization. Without proper handling grievances of the employees well trade unions may call for strikes to force the government to implement their desired changes. In the recent past strikes and go-slows have become common methods which employees use them to pass their grievances to their employers. (Brewster, 1995) It is therefore prudent for management of any organization to adopt employee recognition strategies. This is another factor that the employers put into consideration for the organization to improve its employee relations; this is basically a communication instrument, which strengthens and compensates the most significant production that the employees have created for the organization. The recognition structure is always made simple, instant, and effectively supportive to the employees’ relations and the organization at large. (Chevrier, 2003) Reference: Brewster.

What Is the Bayeux Tapestry?

The Bayeux Tapestry What is it? A band of white linen 70m long and 49. 5cm wide, embroidered with yarn, that depicts the events that led to William of Normandy’s conquest of England and his victory at the Battle of Hastings. What was the Battle of Hastings? A battle fought in south Sussex in October 1066 that determined the successful outcome of the invasion. Harold, then-new King of England, had legitimately succeeded King Edward the Confessor, but William felt the crown was rightfully his because of promises made to him by both Edward and Harold. AuthenticityThis has never been questioned – * Style is consistent with other 11th-century Anglo-Saxon needlework * First referred to in 1476 – displayed once a year at Bayeux cathedral * Halley’s comet appears; astronomers have confirmed this. This detail would not have been known by someone who was not closely connected to the event. Origin (Commission and Creation) Bishop Odo, by general consensus, for the fo llowing reasons: 1. His inclusion in scenes in which he may be considered dispensable 2. The tapestry’s close association with Bayeux cathedral, his ecclesiastical seat. 3.Three minor Norman knights, recorded in the Doomsday book as holding Kentish land from him, are named General consensus is that it was manufactured in England. Evidence for this includes: 1. Stylistic similarity with other Anglo-Saxon art 2. International reputation of English needlework at the time 3. Influence of English language – written in Latin with English syntax; English folk names appear, eg. ?lfgyva Age Potentially 946 years old. Was made between 1067 and 1082 if Bishop Odo was the commissioner – he fell out of favour with William in 1083. Bias It is generally agreed that there is a strong Norman bias.The evidence for this includes: 1. The small amount of attention paid to Edward’s legitimising of Harold and death 2. That a common alternative title, William the Bastard, is nev er used or referred to The attempted justification of the campaign – William is portrayed as reclaiming what was rightfully his and Harold as an untrustworthy oath-breaker, in spite of the strong English case for his kingship, the arguments for which include: a. That King Edward wished him to be successor and legitimately passed it on b. That Harold was a wise, experienced governor c.That William had no claim by descent to the throne It is difficult to determine exactly what has been changed or omitted as empirically-written information is non-existant and the single existing closely-dated English account, The Anglo-Saxon Chronicle, is brief. The only other source that mentions the main contentious point, Harold’s oath, is Norman (Deeds of Duke William, William Poitier). Value to Historians The tapestry provides tremendously important and interesting information to historians about significant Norman characters, their motives and a colourful narrative of an extremely i mportant battle.It is, however, demonstrative of the problem of history-fixing by the victorious side in a controversy. William would have had any unfavourable accounts destroyed had the minority of literate English had the courage to create them. Hence, historians are forced to accept that their only major sources are biased to an unknown degree and compare them with the few facts from other primary sources, eg. dates from gravestones, to develop a somewhat empirical account.

Waiting for Superman

Brad Mitchell Ms. Campbell ENG 101 01 October 2012 Waiting for ‘Superman’ The film â€Å"Waiting for Superman† follows five children as they have to struggle through a system of conflicting education regulations and avoid the academic pitfalls that are public schools in order to receive a proper education that may guarantee them a career. The film, directed by Davis Guggenheim, asserts the claim that Teachers' Unions are a main problem to public education, and that charter schools are the safest and most definite method to ensure that a student acquires a proper education.While the film was created with good intentions to improve the education of American students, it has been dismissed by most due to the film seeming to demonize Teachers’ Unions and overly-praising charter school systems. Although public schools have indeed faltered since the 1970’s, it does not mean that private schools and charter schools are the go-to solution. The truth is, publ ic school systems have been proven to perform just as well as, if not better than, the charter schools that the film seemingly praises as a definitive solution.An article from The Washington Post by Rick Ayers talks about a survey run by the Center for Research on Education Outcomes, or CREDO, saying that it â€Å"concludes that only 17% of charter schools have better test scores than traditional public schools, 46% had gains that were no different than their public counterparts, and 37% were significantly worse. † (Ayers. ) Another popular argument that the film expresses is that the Teachers' Unions should be reformed because the regulations that the unions created make it nearly impossible to fire a bad teacher.Although Teachers' Unions do have room for improvement, throughout history and across the globe the unions have done more good than harm. The American Federation of Teachers and the National Education Association were created to abolish the discriminatory pay rates between male and female teachers, and to establish a firm group to ensure that changes to school systems would not be made without representation and that teachers as a whole would not get the short end of the stick. Waiting for Superman† highlights Finland as having one of the best school systems in the world, while in fact ninety-percent of the Finnish labor force is operated by unions. Dana Goldstein wrote in an article for The Nation: You also don't learn that in the Finnish education system, much cited in the film as the best in the world, teachers are—gasp! —unionized and granted tenure, and families benefit from a cradle-to-grave social welfare system that includes universal daycare, preschool and healthcare, all of which are proven to help children achieve better results at school. Goldstein. ) The film also continuously bashes tenure as ‘good idea turned horribly wrong’, saying that it allows bad teachers to sit in class and do nothing to te ach their students without risk of being fired. Tenure was created to ensure that university professors would not be fired for political reasons or when there was a change in administration. When it branched out to public schools, tenure protected every teacher from being replaced due to absurd reasons like race, religion, or sexual preference.Several surveys have shown that most principals say they would indeed have the authority to fire a terrible teacher if the need arises. The other main point that â€Å"Waiting for Superman† argues about is the funding of public schools versus the funding of charter schools. Public schools are federally funded, meaning that decisions made concerning the school and its administration are made by the state, which fall under a set of federal regulations.Charter schools, however, are privately funded, originally by parents and teachers who were committed enough to start a school under their brand of administration and regulations, as time we nt on, though, more people created their own charter schools mainly for the purpose of gaining more money from applicants and showing little care for the education of students, if only to keep their charter school operating. â€Å"Waiting for Superman† has received both positive and negative reviews since its debut in September 2010. Many critics say that the film is little more than charter school propaganda.While it may seem that way, especially with all the accusations of statistical inaccuracy, the film should not be completely ignored. Davis Guggenheim has fulfilled the purpose of the movie by raising awareness about the quality of public education, and alerting the public to the mess that is the work of Teachers' Unions and theirs' and the governments' conflicting regulations. The United States government and the people of the public must work together and reform and improve the nation's education system for the benefit of their children in the short run, and for the be nefit of their nation in the long run.Works Cited Dana Goldstein. â€Å"Grading ‘Waiting for Superman'. † The Nation. 23 September 2010.
