Sippican Case Study Scm - 1385 Words

1. Given some of the problems with Sippican’s cost system, should executives abandon overhead assignment to product entirely and adopt a contribution margin approach? Why or why not? The overhead spending is greater than the direct labour costs or the direct material costs for all three product lines- Valves, Pumps and Flow Controllers (Exhibit 2). Overheads are simply charged at 185% constant for three diverse products. The fact that there is huge variance in the number of units produced per production run- it is 375 for valves and 18 for flow controllers per production run. This shows the reason for high overheads cost too. Hence it calls for checking the cost allocation system of the company. Since Sippican produces three†¦show more content†¦b) Overheads were first segregated into certain categories like Direct Indirect etc. The reason for this were different costs and different activity on which they are based. Then the time taken for each activity was computed and the costs were allocated based on that. c) The method showed that the pricing that was being used for the three products were not correct. The price at which the pumps were being sold was low were high whereas flow controllers were low. Because of which the most profitable product was coming out to be flow controllers whereas it was actually the least profitable. 4. Based on the revised costs and profitability estimates, what action should Sippican’s management team take to improve company’s profitability? Ans: a) Increase number of units per production run for flow controllers Setup for the machine is done for one batch of items. If we look at the the batch size of valves, it will be 375 units(=7500 units/ 20 production runs)

Argument Against Charles Darwins Theory of Evolution Essay

Charles Darwin proposed the theory of evolution to explain the origin, diversity and complexity of life. I will will disprove evolution by showing that natural selection only explains small evolutionary changes, collectively known as microevolution. Natural selection cannot drive large evolutionary changes, macroevolution. I will also show that the primordial soup, in which life supposedly evolved, did not exist. Neo-Darwinism incorporates the discoveries of modern science into Darwins original theory while leaving the basic beliefs intact. Darwin proposed that individuals with favorable traits are more likely to survive and reproduce. Darwin called this process natural selection. Darwin did not understand how or why variation†¦show more content†¦Natural selection forces animals and plants to adapt. Microevolution happens, and it has been observed in numerous scientific experiments. The real question is not whether or not microevolution happens. It does, but can microevolution be extended to explain large evolutionary changes? Such changes require new genes. Natural selection only optimizes existing genes: If a gene does not exist, it cannot provide a selective advantage. Natural selection only operates on existing genes. When an existing gene tries to evolve into a new gene, the evolving gene must provide some selective advantage, before natural selection can drive the transition. (The declaration of many evolutionists that natural selection drives the transition every step of the way, implies that the evolving gene must perform its new function before it evolves into the new gene. This is like saying a bird with no wings can fly.) Random chance not natural selection is responsible for the evolution of new genes. Until an evolving gene offers some competitive advantage, natural selection is out of the picture. If evolution is not a viable theory, then why is it generally accepted by modern science and why is it often taught as a proven fact in high school and college? To answer this question, let us take a trip back in time to the late 1800s.

Scotland Essays - Norwegian Empire, Council Areas Of Scotland

Scotland The Land Scotland is part of the United Kingdom on the British Isles. It makes up one-third, or 32% of the island. It is bordered on the north and west by the Atlantic Ocean, while the North Sea is to the east of the country. England makes up the southeastern border. The Irish Sea is directly south of Scotland. The total area of the country is a little more than 30,400 square miles. Scotland has a positive-relative location, and is a developed country. There are over 800 islands that are part of the nation, although there are only 186 islands that are inhabited. The majority of Scotland's islands lay on its west coast. They are divided into two groups: the Inner Hebrides, and the Outer Hebrides. The greatest length of Scotland is about 287 miles on the mainland; including the Orkney and Shetland islands to the north would stretch the length to 450 miles. The widest stretch of land is about 150 miles, and the skinniest width goes down to 24 miles. Scotland is divided into three regions: the Highlands, the Central Lowlands, and the Southern Uplands. More than half of Scotland is the Highlands, which is the most rugged region of all of the British Isles. The Highlands contains the highest point in the British Isles: Ben Nevis, part of the Grampian Mountains. The mountain stretches 4,406 feet up. It is a common ambition of climbers to ascend these [Grampian] hills (Horn, 1998). Between the hills are narrow valleys known as glens. Below the Highlands is the Central Lowlands. Contradicting its name, the Lowlands consists of a continuous line of hills. The highest point in this region is Ben Cleuch, reaching up 2,363 feet. The southernmost region of Scotland is the Southern Uplands. Similar to the Highlands, this region is very mountainous; however, the hills are less elevated and less rugged. The hills are more rounded and tend to be grassy. The valleys in this region are a lot wider and less rugged than in the Highlands. The highest summit in the Central Lowlands is Mount Merrick-2,764 feet. Scotland is said to be a country of striking beauty (Horn, 1998). This nation has many deep glacial lakes that are known locally as lochs. The largest lake in all of Britain is Loch Lomond, about 28 square miles. A famous loch is the Loch Ness, which has been the subject of a centuries-old controversy over an alleged monster in its depths (Horn, 1998). There are also numerous inlets of rivers known as firths. Large rivers enter the sea as firths; they are named for the rivers, such as the Clyde River into the Clyde Firth. The major rivers of Scotland, although not used for navigation (besides the Clyde River) include the Tay River, which is the longest in Scotland, the Clyde, Forth, Tweed, Dee, and the Spey River. The Scottish climate is similar to the rest of the countries in Great Britain. The average temperatures are as follows: January ranges from 37-39?F, depending on the area, and July averages between 57-59?F-again depending on the area of the country (Scotland.net, 2000). Typically, the west is warmer than the east in winter months, but temperatures are more equal during the summer. The west also receives the most rainfall-more than 150 inches annually (Horn, 1998). Often the best weather is found in May and September. These are also the months that the northwest of Scotland is relatively midge free (Scotland.com, 2000). The most common species of trees indigenous to Scotland are oak and conifers-chiefly fir, pine, and larch (Encarta, 1999). There are not many woodland areas in Scotland; the only important forests are in the southern and eastern Highlands. Practically all of the cultivated plants of Scotland were imported from America and the European continent (Encarta, 1999). The largest population of a native mammal to Scotland is the deer. The most common type is the red deer, found in the Highlands, but the roe deer are also found. Other native mammals include the hare, rabbit, otter, ermine, pine marten, and wildcat. Popular game birds are the grouse, blackcock, ptarmigan, and waterfowl. Scotland is famous for its abundant supply of salmon and trout in streams and

The Origin and Growth of the Italian Mafia essays

The Origin and Growth of the Italian Mafia essays The Origin and Expansion of the Italian Mafia Mafia. The word that continues to make many quake in fear at the mere mention of it. The Mafia is the longest lasting structured crime organization, it's origins dating back to the 1200's. In those early years the Mafia had just consisted of a few strong men trying to make a buck. Since its initial introduction to Italy, and particularly in Sicily, the Mafia has since fostered and grown into a worldwide crime organization. The origin of the word "mafia" is quite vague. Some experts claim that it came into existence as early as the ninth century, when Arab forces invaded and conquered Sicily. Their Arab rulers oppressed the peasants and many fled to the hills. In Arabic the word "mafia" means refuge. Sicily was subsequently invaded by the Normans in the eleventh century, the French in the twelfth century, the Spanish in the thirteenth century, and suffered from invasions by other nationalities as well. To combat these oppressive invaders, the refugees formed a secret society based on the Sicilian heritage of a sense of family. The organization had a strong hierarchical structure, led by the family heads called "dons." They in turn reported to the "don of dons", who lived in Palermo, the capital of Sicily. All Mafia members, from the lowest ranking informant to the most powerful don obeyed the rule of "Omerta", not revealing any Mafia dealings to the authorities, even about the enemy. Anyone who v iolated Omerta was killed. (History of the Mafia, www.wallwin.org) Others maintain that the word originated during the French invasion when the natives took up the cry, "Morte Alla Francia Italia Anela" (Death to the French is Italy's Cry), or MAFIA, (History of the Mafia, www.wallwin.org) while still others claim the word developed during Sicily's feudal period, when local strongmen were sent to collect the landlord's rents from his tenants (Sicily: Italy Apart...

The Fermentation Process in Wi essays

The Fermentation Process in Wi essays The Fermentation Process in Wine Making Wine making is a long process. After the best grapes have been harvested and pressed they have to go through a process called fermentation. During pressing, when the grapes' skins are broken, yeast, or Saccharomyees ellipsoideus, from the skins comes in contact with the sugar from the insides of the grapes. The yeast enzymes convert the sugar into alcohol and carbon dioxide. They also make various by-products that may add to the wine's flavor and aroma. The carbon dioxide escapes into the air, but the alcohol stays in the grape juice, or must. The longer the must ferments the less sugar it will contain. Dry wines are made by letting complete fermentation take place. This lets the yeast change all the sugar into alcohol. If fermentation is stopped, there will be more sugar left in the wine, and it will be sweeter. Sparkling wines are made by adding more sugar and yeast to the wine after it has been transferred to bottles. A second fermentation builds up carbon dioxide in the bottles and this then produces the bubbles. Fermentation gives off heat, so most wineries refrigerate the must so the temperature stays constant throughout the process. White wines are usually kept at about 59F, and red wines are kept at around 86F. The higher temperature in the red wine allows the color and flavor of the skins to transfer to the wine. Yeast isn't only used in wine making. It is a very useful fungus. ...

There is nothing worse than getting down to some serious study or washing the dishes when a Facebook notification pops up asking if you would like to go to a friend’s birthday party next weekend. Before a decision can be made, the guest list has to be checked (i.e. stalked) to see who is going to be there. If the event is worth going to, then practically every cool person should be attending. Before realizing it, 25 minutes have passed by and studying, or the dishes, has been left far behind. Despite the drawbacks, Facebook and Twitter are not all bad. In fact, they can be quite helpful in the area of homework in particular. For example, study groups can be formed online and classmates can provide encouragement and expertise wherever needed. In the case of a household chore, mentioning it on a Facebook status update or sending out a tweet may provoke a flurry of responses. The key is to leave everyone also while carrying out the chore and only check the reaction

Summary + analysis - Article Example The unique technical features to look out for when identifying a film noir, according to the authors, include the unusual lighting where light and shadow keep opposing, tilted camera angles, and the scene oppositions that are off-center. Film noirs are also characterized by the inversion of customary values and moral ambivalence. The article further notes that, neo-noir, on the other hand, refers to films that followed the noir classic period. Neo-noir also contains noir sensibility and noir themes. They also have similar characteristics to noir such as disorientation, moral ambivalence, pessimism and alienation. Great examples of neo-noir have also been given by the author. These include movies such as Bonnie and Clyde, China Town, Taxi Driver and Body Heat. The author has also described space, time and subjectivity in neo-noir cinema. Different forms of neo-noir time have been described, including past, present and future neo-noir. The author concludes the article by describing the irreconcilable differences of neo-noir. In my personal analysis of the article, the author’s main aim of giving the examples of movies is to demystify the real meaning of film noir and neo-noir. Hollywood film noir is said to have been generated in the early 1940s and the late 1950s. This leaves a lot to be answered because the author has given many examples of movies that were produced as late as 1995 and 1997. Some of these movies should be referred to as neo-noir because they come after the classic noir period. Also, saying that neo-noir films are better at embodying the noir outlook is confusing because noir films had their own unique characteristics and identifying themes. I believe that there should be a clear distinction between noir films and neo-noir films. The investigation of philosophical underpinnings and themes of neo-noir films should also be applied to noir films so as to allow the use of movies to explore and explain traditional philosophical ideas of

Porphyria’s Lover, My Last Duchess and The Laboratory Essay -- Robert

Porphyria’s Lover, My Last Duchess and The Laboratory In this essay I hope to prove that Robert Browning’s murder mystery poems are fulfilled with intrigue and excitement. I also hope to prove that in his poems he creates vivid characters and uses poetic techniques to expose a world of madness and wickedness. To show that the statements above are true I will be writing about the characters, the poetic features in each poem and the madness and wickedness in each poem. This essay will include three of Robert Browning’s poems; they are Porphyria’s Lover, My Last Duchess and The Laboratory. Robert Browning was born on the seventh of May in eighteen twelve in Camberwell a suburb of London. He was the first child of Robert and Sarah Anna Browning. His mother was an accomplished pianist and his Father was a clerk in the Bank of England. Robert Browning was largely self-taught. He was an extremely bright child and a voracious reader. By the time he was fourteen he had learned Latin, Greek, French and Italian. He attended the University of London in eighteen twenty eight but left in discontent to pursue his reading at his own pace. In eighteen forty six he married Elizabeth Barrett and moved to Florence, Italy. He moved back to London in eighteen sixty one but spent his final years with his only son back in Italy. He died in eighteen eighty nine and is buried in Poet’s Corner of Westminster Abbey. He wrote his first poem ‘Pauline’ in eighteen thirty three. Browning wrote during the romantic era in the nineteenth century. In this era romantic poets such as Robert Browning wrote about dramatic events in unusual ways, using different ideas and forms. All of Browning’s poems are dramatic monologues; he was the fir... ... the poison to be attractive so when it is horrible it is more of a shock. ‘The colour’s too grim.

She also shows her wickedness again in the fact that she wants her lover’s mistress to die in pain with him watching her die. I enjoyed all three of the poems but I especially liked reading and studying The Laboratory because I thought it was interesting the way someone could have such a cold attitude to killing someone and actually be eager to do so. All three poems were written as dramatic monologues and they were all about a lover or husband killing their lover or wife because of stupid reasons. I enjoyed the way the poem was written because you felt like you were actually there and they were speaking to you.

Womens Basketball Essay

The average man also tends to be faster ND stronger than the average woman according to Livingston. Com. Women, nonetheless, are very athletic and skilled in their own right and deserve the same recognition as athletes as men receive. The reason their games are not as widely viewed publicly is simply because they are not as fun to watch. For example the average attendance for a Los Angles Lasers game in 2011 was 18,997 people (ESP.. Com). While the average attendance for a Los Angles Sparks game, who plays in the same arena, was 1 0, 1 76 people which is higher than all other WAN teams for that season according to probabilistically. Mom. This can be changed with just a simple tweak of the playing equipment. Handicapping in female sports is quite common; it gives the women the chance to have the same kind of success as the men in their respective sports, which is why lowering the rims in women's basketball would provide more support for the game by making it more entertaining to watch which would mean higher attended games and more television viewers. If the rims were lowered, women's basketball would be much more entertaining to watch.Women would be able to finish shots closer to the rim teeter which would result in higher scoring and much more exciting games. The reason men have such a large following worldwide is because people love watching some of the best athletes in the world do things on a court with a ball that nobody else can do. Women's basketball players are no different. They, too, are the some of the best athletes in the world, but they just can't do everything on a court that a man can do because they are naturally built differently.Men tend to be much taller and stronger than women, and are able to jump higher and play much more aggressively. Lowering the rim, even just seven inches, would allow the female players to do more of the things that men can do, like dunk and hit high level of difficulty shots more often. One of the main promoters of th is idea is the University of Connecticut head women's basketball coach Gene Uremia, a seven time national champion with the Huskies who also led the women's IIS Olympic team to a gold medal this past summer in London. What makes fans not want to watch women's basketball is that some of the players can't shoot and they miss lay-ups and that forces the game to slow down,† states Uremia (Gregory). He argues hat the lowering of the rim would increase the shooting percentages and increase the final scores, making it an overall much more exciting game to watch. This would in turn result in an increased audience and would be beneficial for the growth of the game and the women getting the attention and respect that they deserve. Adjusting the playing equipment in women's sports is a very common practice.The nets are lower than the men's in women's volleyball, the tees are moved up closer to the pin in golf, softball fields are smaller than baseball fields, and even in basketball their balls are already smaller to account for hysterical differences. That is why it is not unjust or sexist to propose lowering the rims to adjust to women's differences in size and athleticism, for it would only be beneficial for female sports. It is unfair to expect women to play on a 10 foot rim and still get the type of attention that men get. The difference in athleticism and size just won't allow for that. In 2007, NAB. Mom did a survey and found that the average NAB player is six feet and nine inches tall. A similar survey done in 2003 by WAN. Com found that the average height of a player is five feet eleven inches tall. This difference is the exact reason why men are dunking and women aren't, but more importantly, why people are watching the men's games but not the women's games. Men are taller and have an easier time dunking and finishing off balance shots, while the smaller women have to work harder to put the ball through the basket. Basketball fans like to see the high scor ing games and the powerful slam-dunks.This is proven by the NAB All-Star weekend in which there is not only an All-Star game, but a Slam-Dunk contest and Three-Point contest as well which totaled in 2,729,000 viewers in 2012 (Savage). The WAN All-Star game had a total of 756,000 viewers in 201 1 (Costa). These numbers show how much more people would rather watch the men play then the women. Changes need to be made to even these numbers out. Other sports have followed this blueprint where the equipment used is adjusted to make them more successful, and it is time that basketball followed suit.Lowering the rims in women's basketball is a very controversial and not yet widespread topic. In fact, it is a very new subject that is only recently gaining attention. There are many opponents to the idea of the basket being lowered or women, as well as many hurdles to get through in order for it to take effect. In order for this to happen, there would have to be a long process of meetings and rule changes and an agreement between all leagues of women's basketball both collegiate and professionally.The NCAA released a statement saying, â€Å"The NCAA continues to work with its members and others to grow the game Of women's basketball, but the issue Coach Uremia has raised is not before our membership for consideration† (AltaVista). Also, almost every gym that women play in is the home court to a men's team as ell. So there are ID foot baskets in every facility already, and switching all of those to height adjustable rims would require a significant renovation. There are also critics of this idea who believe lowering the rims is an insult to female athletes everywhere: â€Å"†¦ Roaring the rims would further ostracize young girls who are trying to learn the game on courts across the country, often right alongside boys,† states Kate Fagan, a writer for ASPEN. Com, a women's sports site: (Lowering) â€Å"The problem is people insist on comparing it to the men's game, suggesting women would attract more fans if they dunked and played above the rim, like men. This obsession with comparing women's basketball to men's doesn't exist in other sports†¦ F the argument is that people don ‘t watch women's basketball because it's slower and less explosive, then lowering the rim all the rims, for girls and women every/here does nothing to change that' (Fagan). The entertainment factor does not appeal to many that are close to the game, and they are happy with how the sport is and feel it needs no change. What Pagan's argument fails to mention though, is that professional women's settable is hardly a profitable organization. The average NAB player makes about $3 million per year, while the average WAN player makes about $35,880 per year.Why shouldn't men and women be paid the same for playing the same game and working just as hard? The only way this will happen is if women's basketball gains more fans and becomes just as popular and g lorified as the men's games. Like the adjustments for women in other sports, lowering the rim would give women a chance to be more successful which would in turn make the game more entertaining to watch. By more people watching the games and giving it more support, both the NCAA and WAN would gain more fans and more money.With this money, WAN teams could get television deals like the NAB teams, which would mean more young girls could watch the games and be motivated to go and pick up a basketball themselves. The more young women there are that play basketball, the better the competition will be which would result in even better players then there are today. Basketball is a great sport and women deserve just as much recognition for their talents as the men receive. Lowering the rim would provide all that it would lead to more equality between men's and women's basketball.

The inadequacy of motivation Essay

Sixth, there are some individuals who are more successful than others because of their sicknesses and the discrimination that goes along with it. For example, there may be students who suffer from HIV/AIDS and they tend to drop out of school because of discrimination (Cape.. , 2006). Other students may feel and believe that they might catch the same virus if somebody carries it around the school, this consequently scares these students and will surely discriminate the student suffering from HIV/AIDS (Cape.., 2006). Of course the latter will feel alone and discriminated and will force himself or herself to just forget about his or her dreams and drop out of school instead (Cape.. , 2006). Comparing to students who do not carry any medical condition, they are more successful in college than those who are sick. Seventh is labeled as â€Å"the inadequacy of balance between analytical, creative, as well as, critical thinking† (Smith, 1923). A college student should learn the skills of thinking analytically, creatively and critically to be able to survive through the courses needed to be accomplished to finish college, for without the aforementioned skills, it would be fairly difficult to pass college courses, much less finish a degree (Smith, 1923). For some students who are not analytical, creative and critical thinkers, they are less successful as compared with those who are. Last but not least has something to do with the culture of the learner’s environment: The first one that belongs to this category is technically referred to as â€Å"the inadequacy of motivation† (Smith, 1923). The trick here is to know the reason for studying. The student should know what his or her goals and objectives are, otherwise, when difficulties emerge, the student will have no motivation or reason to move on (Smith, 1923). The second is known as â€Å"the attitude of giving up easily† (Smith, 1923). Everybody knows that it takes dedication, time, effort, patience, and a lot of mental energy to digest a new learning that if a student is bound to easily give up and get bored over repetition of things then most likely he will end up leaving college without graduating (Smith, 1923). Some students in college are more successful depending on their motivation and attitude. References Cape Gateway. (2006). Social Issues Affecting School.

Origin of the Name Newfoundland and Labrador

Origin of the Name Newfoundland and Labrador The province of Newfoundland and Labrador is one of the ten provinces and three territories that make up Canada. Newfoundland is one of four Atlantic provinces in Canada. Origin of the Names Newfoundland and Labrador King Henry VII of England referred to the land discovered by John Cabot in 1497 as the â€Å"New Found Launde, thus helping to coin the name of Newfoundland.   It is thought that the name Labrador came from Joo Fernandes, a Portuguese explorer. He was a llavrador, or landowner, who explored the coast of Greenland. References to the labradors land evolved into the areas new name: Labrador. The term was first applied to a section of the coast of Greenland, but the area of Labrador now includes all the northern islands in the region. Previously called only Newfoundland, the province officially became Newfoundland and Labrador in December 2001, when an amendment was made to the Constitution of Canada.

Republicans vs Democrats

Republicans vs Democrats Free Online Research Papers It seems that the backdrop more every major political race is the butting heads of conservatism versus liberalism, Republican versus Democrat. The confusion that may accompany the barrage of information presented may actually deter people from voting at all. In fact, the two parties ideologies seem to share many of the same goals for the economy, foreign policy, and personal liberties. Furthermore, both Democrats, the supposedly liberal party, and Republicans, the supposedly conservative party, have been appointed to the highest office, the President of the United States of America. In most cases, the President has been effective in building notable progress in our nations growth, regardless of the political party that they belong to. Upon closer examination into the history of the Democratic and the Republican parties, we are able to determine that the political philosophies from which they originate have glaring contrasts in their ideologies, but may also share a few similariti es. The Republican Party was created in 1854 in opposition to the Kansas-Nebraska Act that would have allowed the expansion of slavery into Kansas. As well as opposing the expansion of slavery, the group also emphasized higher education, banking, railroads, industry and cities, and promised free homesteads to farmers.(wikipedia.org) Republicans are generally seen as the conservative party. Conservatives are strong defenders of liberty. They value small government, fiscal restraint, and individual rights responsibilities. Conservatives tend to emphasize traditional views of social units such as the family or church, and often use history as a means to justify their beliefs. A conservative political philosophy is based on tradition and social stability, stressing established institutions, and preferring gradual development to abrupt change. ( merriam-webster.com) Conservatives seem to favor a Pyramid approach to politics, allowing the government to decide what is best for the greate r good. As seen with Madison’s Federalist #10, conservatives believe in a strong controlling government. According to conservatives, a Republican government can be relied upon to make decisions that will benefit the greater good of the country. Historically, conservative thought supported the idea of individuals being economically responsible for their own actions and decisions, and sought to preserve property rights rather than redistribute wealth or reduce inequality. As evident in Sumner’s Rich are Good Natured piece, conservative thinkers feel that hard work is justly rewarded. Today’s Republicans offer a more practical approach to politics, while still staying true to their conservative values. According to GOP.com, Republicans have always been the Party of fresh ideas and new thinking. They encourage debate on the major issues of our day, and consistently act in accord with the greatest values of our country – freedom and opportunity for all. Their plans focus on ensuring that America remains safe, terrorists are defeated, and democracy flourishes in the world †¦ on expanding opportunities for ownership and investment †¦ on making tax relief permanent and ensuring greater energy independence †¦ on increasing the affordability and accessibility of health care †¦ on promoting works of compassion and strengthening our greatest values †¦ on preparing students for success in life by bringing the benefits of education reform to high schools †¦ and on helping workers adjust to a changing economy by offering flexible training options that meet their individual needs. The Democratic Party is the oldest political party in continuous operation in the United States and it is one of the oldest parties in the world. The Democratic Party traces it’s origins to the Democratic-Republican Party, founded by Thomas Jefferson, James Madison, and other influential opponents of the federalists in 1972.(wikipedia.org) Democrats are generally seen as the more liberal of the two dominant political parties. Liberal thought usually considers individual liberty and equality to be the most important political goals, emphasizing individual rights and equality of opportunity. Liberalism encompasses a fish bowl style political model, promoting a non- hierarchical government. In William Jennings Bryan’s cross of gold speech he talks about treating the man who is employed with same amount of respect as his employer. This is a perfect example of the liberalistic attitude of equal opportunity and protection of individual liberties. The Merriam-Webster dictionary defines liberalism as a political philosophy based on belief in progress, the essential goodness of the human race, and the autonomy of the individual and standing for the protection of political and civil liberties. Today’s Democratic Party adheres to basic beliefs found in historical liberalism. The Democratic Party is committed to keeping our nation safe and expanding opportunity for every American. That commitment is reflected in an agenda that emphasizes the strong economic growth, affordable health care for all Americans, retirement security, open, honest and accountable government, and securing our nation while protecting our civil rights and liberties.(democrats.org) While Conservative policies generally emphasize empowerment of the individual to solve problems, Liberal policies generally emphasize the need for the government to solve peoples problems. Conservatives believe in personal responsibility, limited government, free markets, individual liberty, traditional American values and a strong national defense. They believe the role of government should be to provide people the freedom necessary to pursue their own goals. Liberals believe in governmental action to achieve equal opportunity and equality for all, and that it is the duty of the State to alleviate social ills and to protect civil liberties and individual and human rights. They believe the role of the government should be to guarantee that no one is in need. Clearly there are many differences in where Republicans and Democrats base their ideologies. However, there are significant similarities that deserve to be noted. Republicans and Democrats are in general agreement about the qualities they are looking for in the president of the United States. Both sides demand honesty, strong leadership, management skills, and moral integrity in the nation’s president. Both sides also put lower emphasis on military experience, business experience, political experience, and religious commitment. (gallup.com) Republicans and Democrats share similar views on the importance of individual rights, although they emphasize different areas. Democrats want more individual freedoms in social areas such as free speech, while Republicans emphasize individual freedoms in areas such as business. Republicans and Democrats both believe in the power of a centralized government; however Democrats want the government to regulate business and protect the minorities of society, where Republicans want government to enforce societal norms and protect business. During political campaigns, it is sometimes difficult to sort through the static and get to the candidates real views on issues. I think it is important to look at the opposing parties core beliefs, and decide who you identify with more. While you may agree with the Democratic candidate on some issues, a Republican candidate may seem more capable in remedying other issues. Unfortunately, you can only pick one! Looking at the ideologies that political parties subscribe to may help in deciphering the differences in candidate’s beliefs, and empower people with the knowledge they need to make an educated decision as to who they would vote for as President.

Health and Safety Report - Essay Example The paper includes aspects of case laws with respect to the initiation and spread of fire. It goes on to point out some aspects related to emergency evacuation and strategies. All these aspects are collaborated with relevant legislations, fire preventive measures, the protective measures, as well as relevant fire fighting devices. The paper argues that resulting effects and the situations leading to fire outbreak call for the need to develop a good plan of action for handling cases of fire outbreaks. People could as well come up with elaborate plans that would prevent fire outbreaks within their environs. Organisations holding the responsibilities to contain fire outbreaks need to introduce fire fighting gadgets and chemicals that can fasten process of extinguishing fire. The fire fighting departments need to ensure that there are good indicators of places likely to be a threat to the people. Besides, these indicators should be in a way that can warn the people about the issues that they are likely to face as the paper depicts. In most of the buildings, fire fighting strategies need to be established to ensure that the people residing or working in such buildings are in a position of containing situations that may face them as a result of fire outbreaks. This situation could be even more difficult to the people living in high rising buildings. In this case, the fire department needs to establish an elaborate design to ensure that cases of fire fighting are settled as much as possible. This means that fire-fighting departments need to develop and advocate for good fire fighting plans that ensure that people achieves their goals in solving fire accidents within a short period (Communities and Local Government 2007). On another hand, there is the need to establish some good plans of building in ways that enhance the safety of people, especially during a fire incident. Apparently, within the plans of designing these buildings, there need to be emergency escape

Latin America Essay Example | Topics and Well Written Essays - 500 words

Latin America - Essay Example The human population has changed and continues to change the landscape from natural to the cultural landscape in various ways. One of the significant ways that have seen a transformation of the landscape is through increasing agricultural activities. This has been intense especially with the rising human population. Humans have cut, cleared, and burned forest for agricultural activities (Erickson, n.d.). An example of human built landscape is the area next to Lake Titicaca (Erickson, n.d.). In this area, there have been heightened agricultural activities. In the last eight century, the environment in the basin has been changed into an artificial landscape (Erickson, n.d.). This has been mainly due to raised fields, terracing, and irrigation activities that are related to agriculture. The other factor that leads to change of landscape is clearing of forest. The region has witnessed a massive loss of forest cover for a long period. In fact, the region is noted to have the world’s highest loss of forest cover in the recent past (Pacheco et al., 2011). However, extensive forest transformation has been witnessed in the Amazon basin (Pacheco et al., 2011). As the authors note, huge population in the region relies on forest resources to support their livelihoods (Pacheco et al., 2011). The population also comprises of ranchers and farmers that continue to clear forest to create space for their activities. As a result, most of the land that was previously occupied by trees is left bare. The changing geography in the region has a profound impact on regional political future and institutions. One of the issues related to change is the rise in conflict between people, countries, and region in the area. For example, there has been increasing conflict over the use of resources such as those that come from the forest. On the other hand, failure to guard

Social Judgments Essay Example | Topics and Well Written Essays - 500 words

Social Judgments - Essay Example Does this mean that if we want people to stop acting a certain way toward us that we should amplify the behaviors that confirm their beliefs about us Researchers investigated the demarcation of automatic and controlled processes in such prejudice (Devine 1998). They suggested the stereotype is automatically activated in the presence of the stereotyped group and that low-prejudice people deliberately inhibited the activation of the stereotype and only low-prejudice people inhibited automatic stereotype-congruent thinking. These studies suggest that in order to rectify stereotypical thinking, a person must be proactive in combating culturally biased thoughts internally. Does this mean that if we want people to not believe that stereotypes about our social group apply to us that we should avoid associated stereotypical behaviors Stapel and Blanten thought that such social comparisons influence one's perception of self (2004). They tested to determine whether subliminal exposure to comparative information influences either implicit or explicit self-evaluation. This study showed that automatic comparisons only occur when people are uncertain about themselves and need reassurance. When we are feeling grave self-doubt, socially comparative information automatically effects how we see ourselves. Does this mean to be confident in who we are we must maintain a positive attitude How we

Is Beer Becoming More Concentrated Essay Example for Free

Is Beer Becoming More Concentrated Essay At first glance, the UK brewing industry might appear to be highly competitive, with many pubs in close proximity to one another and with many brands of beer and lager offered for sale. However, in reality most pubs are owned by the major brewers. Tied houses, as they are called, account for about 40 per cent of a brewer’s turnover, and sell only a limited range of the beers and lagers that are available. Consumer choice is clearly constrained. The oligopolistic nature of the brewing industry can be seen when we consider the market shares of the leading brewers (see table). In 1985 the three largest brewers held 47 per cent of the market. By 2001 this had grown to 73 per cent. What is also significant is that small independent brewers, which generally operate within a local or regional market, have seen a dramatic fall in their market share. With this huge growth in the market power of the major brewers have come large rises in the price of beer (even after taking inflation and tax increases into account). Prices in the UK have risen faster than anywhere else in Europe. Market shares of the largest brewers | |1985 | | |2005 | | |(%) | | |(%) | |Bass |22 | |Scottish-Courage |27 | |Allied Lyons (Carlsberg) |13 | |Coors (Carling, Worthington) |20 | |Grand Met (Watneys) |12 | |! nbev (Bass, Beck’s, Stella) |19 | |Whitbread |11 | |Carlsberg UK (Carlsberg, Tetley’s) |13 | |Scottish and Newcastle |10 | |Diageo (Guinness) |6 | |Courage |9 | |Anheuser-Busch (Budweiser) |2 | |Others |23 | |Others |13 | |Total |100 | |Total |100 | |3-firm concentration ratio |47 | |3-firm concentration ratio |66 | |5-firm concentration ratio |68 | |5-firm concentration ratio |85 | 1987, the Monopolies and Mergers Commission, the forerunner to the Competition Commission (see section 6. 6), investigated the brewing industry and in 1989 issued the ‘Beer Orders’, requiring the large brewers to sell many of their pubs. The objective was to increase competition as smaller brewers and other companies and individuals bought these pubs and then stocked a range of beers. However, the hopes were ill-founded. The pubs that were sold were the least profitable, and many have since closed. There is thus now less competition between pubs. Also, about 40 per cent of UK pubs are now owed by large pub chains. The Beer Orders also required that over 10 000 pubs owned by the big breweries should stock ‘guest beers’ from rival breweries. But the big breweries responded by selling most of these pubs. In pubs not owned by the big breweries, and where there is the threat of genuine competition, the big breweries often supply their beers at lower prices, thus making it impossible for the smaller breweries to compete. The brewers, finding a reduction in their scope for achieving economies of scale from vertical integration (owning both breweries and pubs), have sought to gain economies of scale from horizontal integration (having a larger share of total brewing). Mergers and takeovers in the brewing industry have been common. For example, in May 2000 Interbrew (the Belgian brewer and owners of the Stella Artois brand) acquired Whitbread, the UK’s third largest brewer, and a month later acquired Bass, the second largest. This gave Interbrew nearly one third of the market. The acquisitions were referred to the Competition Commission, which recommended a break up of the new giant: a recommendation accepted by the government. In response, at the end of 2001 Interbrew (now called !nbev) sold most of the Whitbread division, including brands such as Carling, Caffrey’s and Worthington, to the US brewer Coors. In the light of this splitting of Interbrew, and feeling that this proved that competition policy was effective, the government in 2002 decided to scrap the Beer Orders. This was greeted with dismay by small independent brewers, which were already reluctant to expand, faced with the power of such massive competitors in both production and retail, with heavily advertised brands gaining larger and larger shares of the market. Small independent brewers are understandably reluctant to expand, faced with the power of such massive competitors in both production and retail, with heavily advertised brands gaining larger and larger shares of the market. |Questions | |1. What are the barriers to entry in (a) brewing; (b) opening new pubs? | |2. Do small independent brewers have any market advantages?

In the period after Reconstruction the position of African Americans in southern American society steadily deteriorated. After 1877 the possibilities of advancements for African Americans disappeared almost completely. African Americans experienced a loss of voting rights and political power created by methods of terrorization such as lynching. The remaining political and economic gains that were made during reconstruction were eventually whittled away by Southern legislation. By the 1900s African Americans had almost no access to political, social, or economic power. Shortly after this Jim Crow laws began to emerge, segregating blacks and whites. This dramatic transition from African American power to powerlessness after reconstruction gave birth to two important leaders in the African American community, Booker T. Washington and W.E.B. DuBois. Although these two remarkable men were both in search of a common goal, their roads leading to this goal were significantly different. This is most evident in the two most important documents of the men’s careers: Booker T. Washington’s, â€Å"1895 Atlanta Exposition Speech† and W.E.B. DuBois’ response to this, â€Å"The Souls of Black Folks.† These two men were both dedicated to solving the difficult problems African Americans experienced in the post reconstruction south. Both DuBois and Washington wanted economic prosperity for African Americans but they differed on what would be done to achieve this. Both men focused on education as a key to the improvement of black life but they differed on the form education should take. The true difference in these men’s extremely different routes to better the lives of African Americans after reconstruction was a product of their extremely different backgrounds. In this essay I will examine the documents, â€Å"1895 Atlanta Exposition Speech† by Booker T. Washington and W.E.B. DuBois’, â€Å"The Souls of Black Folks† in order to determine the paths that each of these men took towards the advancement of African Americans, and the reasons behind these methods. DuBois and Washington came from extremely different backgrounds. These differences are essential to understanding why each of these men went about trying to achieve progress for their race in the way they did. DuBois, the son of free parents, was born a free man and grew up in a white environment with more privileges and advantages than the majority of African Americans living in the United States at that time. He suffered neither severe economic hardship nor from repeated encounters with racism. In contrast, Booker T.

8 Steps of an Advertising Campaign Essay

Here are eight steps you can follow to keep your advertising campaign on track and successful: Market research: Before you even start thinking about where you might want to place an ad or even what it could look like, it’s important to do at least some basic research. Even if you aren’t in a position to bring in an expensive research firm, you can ask your current customers questions about why they come back to you, as well as taking a close look at your target demographic’s needs and interests. Budgeting: Your business probably has a set advertising budget for the year — but how do you divvy it up between your various advertising projects? For each project you’re planning, you need to be clear on just how much money you’re willing to spend. You’ll almost certainly change exactly how you divide it between costs like copy writing and design, but you can treat the overall amount as set in stone. Write it down and put it in your project folder. Setting goals: The aims you have in mind for a particular advertising project need to be written down ahead of time. While it’s good to be ambitious, it’s also important to decide what constitutes a successful advertising campaign for your business. Sales can be the simplest metric: if you’re advertising a particular product, how many units will you need to sell to pay for that campaign? Advertising venue: The website, tv station, newspaper, radio station, magazine or other advertising venue you place your ad with is a crucial decision. You’ll need to look at not only the cost of your preferred venues but also whether they reach your target demographic. Ad buys can make up a significant portion of your budget. Deciding on where you will place your ads first tells you how much money you’ll have left over for actually creating your ad. Choosing creatives: Unless you’re planning to write, shoot and design every part of your ad, you’ll probaably need to bring in some help. Finding the right freelancers for each aspect requires checking through portfolios and rates — if you can find a business or freelancer who can handle all aspects of creating your ad, even if that means subcontracting, it can save you a lot of time. You’ll also want to make sure that you find any talent you’ll need for your ad (voice actors for radio, models for photography and so on). Design and wording: While you may not have a lot of actual writing and designing to do for your ad, during the creation process you will need to review and sign off on different stages of the project. When starting with a new designer or other creative, make sure that you both know any expectations for timelines and progress checks. Placing the ad: Once you have a finished ad in hand, it’s time to actually place it with your preferred advertising venue. You may have a few contracts to sign and a check to hand over. You’ll also want to make sure you actually see your ad once it’s run — from a newspaper, for instance, you’ll want to see the tear sheets of pages containing your ad. Evaluation: Depending on your ad, how you evaluate it can vary. If it included a coupon, for instance, you can simply count how many customers brought in the coupon. For other ads, you may be simply comparing sales before, during and after your advertising campaign. Spend as much time on analyzing how your advertising campaign worked as you can. That information can point you to more effective uses of advertising in the future. While following such a set process may seem like it would stifle the creativity necessary to put together a new ad, following these steps can actually make it easier. You can minimize confusion and make sure that everyone is meeting the necessary deadlines — and you can ensure that you’ll be able to measure your ad’s actual cost and responses during each step. You’ll be better equipped to tweak your ad or move it to another publication in the future.

Entamoeba histolytica

E. olytica is a pathogenic amoeba. There are trophozoit cyst stages in its life cycle. Only the mature cyst (with 4 nucl infective. Men get infection by mouth. The amoebae inhabit the colon. They multiply by binary fission. The cysts passout with The life cycle of E. histolytica is cyst–trophozoite–cyst. The trophozoites may invade the intestinal wall or even liver and lung tissues by blood dissemination and induce pathological changes. I. Morphology. There are 4 distinct stages in its life cycle; trophozoite, precyst, cyst, and metacyst, but only the morphology of trophozoite and cyst possess morphologic characteristics that have diagnostic value. A. ophoite – active form. a. ize trophozoites vary in size from -60 micrometers in diameterb. Movement is by means of a pseudopodium, which is a cytoplasmic protrusion. The characteristics of pseudopodia of Entamoeba histolytica are: (1) broad or finger-like in form (2) thrust out quickly (3) pseudopodium first formed with hyaline ectoplasm, then the granular endoplasm flows slowly into pseudopodium when amoeba move (so called amoeba movement). 4) motility is progressive and directional c. Red blood cells may be found in the endoplasm. d. Nucleus, vesicular type: The nucleus is not visible in anunstained specimen, but when stained with hematoxylin, the nuclear structure will be clear. (1) Nuclear membrane is a delicate but distinct line. (2) Peripheral chromatin granules are fine and uniformally arranged on the inner surface of the nuclear membrane. (3) Karyosome is small and centrally located. The characteristics of the nucleus of E. istolytica are useful in differentiation of the pathogenic amoeba from the other non-pathogenic species. B. Cyst-Non-Motile (has no movement) Before encysting, trophozoites round up, cease ingesting food, and secrete a cyst wall, thus becoming a precyst, and then an immature and mature cyst. a. Immature cyst – spherical in shape, 10-20 Nm in size, and consists of 1-2 nucleus or nuclei. b. Mature cysts: 4 nucle. The characteristics of the cyst nucleus are similar to that of the trophozoite. Besides nuclei, there are two other inclusions: the glycogen vacuole and the chromatoid bodies (bars). Both the glycogen and chromatoid bars become smaller and smaller as the cyst ages, so sometimes they cannot be seen in the mature cysts. The glycogen acts as a food reservoir,but the function of the chromatoid bar is not known. When the cyst is stained with iodine, the glycogen appears brown or dark yellow brown in color, but the chromatoid bar can not be stained and has a refractory appearance. In iron-hematoxylin stained specimens, the chromatoid bar is rod shaped with two rounded ends and dark blue in color. he glycogen vacuole has been dissolved during the process of staining, so it appears as a clear space. II. Life cycle The normal life cycle of E. hystilytica is cyst-trophozoit-cyst III. Diagnosis (1) trophozoite (living): fecal examination (direct smear with normal saline) for the diagnosis of amoebic dysentery. One must pay attention to: a. The container must be clean and free of acid or alkaline. b. Trophozoites should be examined soon after they have been passed c. Keep specimen warm in order to keep the trophozoite's activity. d. Select the bloody and mucous portion for examination. e. If Charcot-leyden crystals are present, the stool must be carefully examinedfor the trophozoites of Entamoeba histolytica ( charcot-leyden crystals may be derived from eosinophiles). (2) Cyst: fecal examination (direct smear with iodine stain) for the chronic intestinal amoebiasis or carriers. Immature and mature cysts of E. histolytica may be found in the formed stool.
