Love in Knights Tale and Wife of Baths Tale Essay -- Chaucers Cante

Love in Knight's Tale and Wife of Bath's Tale The Canterbury Tales, written by Geoffrey Chaucer around 1386, is a collection of tale told by pilgrims on a religious pilgrimage. Two of these tales, "The Knight's Tale" and "The Wife of Bath's Tale", involve different kinds of love and different love relationships. Some of the loves are based on nobility, some are forced, and some are based on mutual respect for each partner. My idea of love is one that combines aspects from each of the tales told in The Canterbury Tales. In "The Knight's Tale", the love between the two knights and Emelye is intensely powerful. The love that Palomon and Arcite feel towards Emelye is so strong that the two knights feel that it is worth more than their own lives. At one point, Palomon tells Arcite that he shall either have Emelye or he shall die. The love that Palomon feels for Emelye is so overwhelming that he is willing to take on an armed man, in mortal combat, just for the love of a woman. Perhaps he feels that without her, he will surely die, so why not die trying to win her? The ironic fact about the relationship between each knight and Emelye is the fact that Emelye does not wish to marry either of the knights. She is aware that she is just a prized possession, one that is not fully known, because she has never exchanged a single word with either gentleman. However, in that time period, she could not easily express her feelings, and if she were able to, those feelings would most likely be ignored. Like already mentioned, this is so ironic because Arcite and Palomon are about to kill each other for Emelye's love and she doesn't want to be loved by either of them. She enjoys the thrills of maidenhood too much to have them ended by ... .... The Wife of Bath has used men in her life for riches. She leans toward a feminist nature and seems resentful toward most men. For women, she is easy to respect and admire. She is an intelligent woman, however, she may not know the limits of her games. That is the beauty of society. Thousands of years after this novel has been written, men and women still don not know what one another want. In taking both Psychology and Sociology this year, I hope to grasp a better understanding on how both sexes co-exist with one another.

Change and Continuity in Constantinople

Constantinople was a city with a long a diverse history especially through the years of 1450 to 1750. Between these to dates Constantinople changed drastically in its political structure. Constantinople also had a tremendous chance in its trade activity. Innovation both militarily and nonmilitary within this city however remained virtually unchanged between 1450 to 1750. In short Constantinople transformed itself between 1450 to 1750 in the fields of government and business, but remained constant in its technological advancements. In the area of politics the chance of Constantinople couldn’t have been more drastic in the years between 1450 and 1750. In1453 the Byzantine Empire fell to the Ottoman Empire in the siege of Constantinople. This in turn allowed the Ottoman Turks to take Constantinople and completely defeat the rest of the remaining Byzantine Empire. The Ottoman Empire renamed the city to Istanbul and made it one of there capitals of there empire that ruled most all of the Middle East. The city was extremely vulnerable to attack because of the forth crusades that sacked the city and heavily depleted its population and allowed ottomans to take it. This new government allowed for the growth of religions, even make Constantinople a once Christian stronghold to a predominantly Muslim city. This new government also allowed for a large rise in population going from a few thousand in the 15th century to the over half a million in the 18th century. This was caused by an increase of culture and artwork due to the leadership of Suleiman the Magnificent. The other massive change in Constantinople between 1450 to 1750 was the amount of trade that was preformed. The lack of trade was because of Ottoman conquering of the city in 1453. This capture of the city created total dominance of the Middle East created a regional block of all trade routes effectively creating an Ottoman trade monopoly which allowed the Ottomans to charge whatever they wanted, this made it unprofitable to trade for the Asian goods that Europeans wanted so bad. This was the largest reason for the Europe’s age of exploration. The simple fact that the prices were too high making trade impractical causing a lack of trade and Europeans looking to the sea for trade with Asia. This in contrast with the previous large amounts of trade that use to go through Constantinople because of its great location between the Black Sea and the Mediterranean. Those most elements of the city of Constantinople were changed by the new empire that ruled it the one thing that stayed the same was the technology that was used in Constantinople. The Ottoman Turks were very regressive and didn’t embrace new technologies. This lack of progression caused by the Ottoman conservative clergy plus the lack of trade cause a lack of diffusion and a lack of advancements in there society. This all the while the rest of the world was making leaps and bounds forward. This was what caused the long term demise of the Ottoman.

The Fashion Channel

The Fashion Channel The Fashion Channel has dominated the fashion television market in recent years, but is now faced with an increasing amount of formidable competition. Both CNN and Lifetime have added fashion related programming after seeing an opportunity to gain viewers in that market. These two competitors have been relatively successful in securing a following of viewers.The fashion channel now must make the decision on how to move forward with their marketing plan. They must find the best scenario possible in order increase revenue and secure viewers in this increasingly competitive market. To successfully do execute this plan, The Fashion channel must review the customer segments, complete a profit potential analysis, and chose a marketing plan that best suits their needs and the needs of their viewers.

Focus on planning and saving when shoppingI would make this the secondary segment. | They don’t shop a whole lot, but they enjoy hearing about fashion. You could dip into this section if you had the resources. | This segment shows now interest in fashion. We believe they should avoid targeting this market. | Methodology Fashionistas: Demographics: Females tend to be more fashion oriented from head to toe than men. This segment h as a high income, which they need to be able to keep up with the trends and the expensive luxury brands.Women between the ages 18-35 are the majority of this market. This is the age range when women try to appeal to others by their looks. Key attitudes and beliefs: They want to have the new and latest clothes and accessories. This segment tends to wear expensive brands to show people they can afford nice clothes and care how they look. They don’t care how much it cost, with their high income they will buy whatever is fashion, even if its outrageously priced. Interest in fashion They enjoy watching fashion on TV (Heavy watchers), they treat it as an entertainment. This is how they keep up with the trends. They also keep up with the fashion through social media and magazines.Assessment: This is the smallest market although they are the ones that fit Fashion TV’s criteria. They are like the pioneers to early adopters in fashion. If they like it they will spread the word t o others, then they start watching the program. This makes it a key factor to target this market well; you want them to likes your programs, so they well send out good recommendations to others. Planners and Shoppers: Demographics: This segment also leans towards females (60%). The age range for this segment is 21-45. The young side of the segment is young and with lower incomes. The older side of the segment likes to be thrifty and get the best deal for their dollar, even though they make good money. They have an income of 65,000+.They have enough income to spend on nice clothes, but need to find the best deals to stay within their budget. Key attitudes and beliefs: This segment still likes to look good, but is on a budget, so they look for the best deals. If an item is on sale they are more prone to purchase it. They tend to be loyal to certain brands. They stick with certain brands, to receive loyalty coupons and other discounts. Interest in fashion: This segment has pretty simil ar interest in fashion as the fashionistas. They would watch shows that deal more with value, like how to look good with under $100. Assessment: This segment has the largest size, which makes it an attractive market to target; the numbers agree this is a good segment.They watch fashion TV and enjoy planning shopping trips. You could market shows that deal with planning shopping trips and how to shop on a budget. Situationalists: Demographics: Found this segment to be made up of male and female. With about 50% of the populations having kids living at their home still, they have less of a disposable income. Parents with kids living at home tend to range between 24-50 years of age. Key attitudes and beliefs: Fashion only occurs to them in special occasions. They typically don’t spend a lot on clothes, but for certain occasions they splurge a little bit. They are somewhat price sensitive, because of their low disposable income.Interest in fashion: While the other segments watch T V for tips and trend, this segments tends to watch TV recreational. They don’t watch it daily. Assessment: We believe the previous two segments are more attractive than this one, although they could dip into this segment. Situantiolists show some interest in fashion. Having a wedding dress show is something that would intrigue this audience. Shows that deal with special occasions, weddings are the big one. This group wants information about fashion for the key moments of their lives. Basics: Demographics: The majority of this segment tends to be male. The age range of the segment is 28-50. Men younger than 28 years old care more about their appearance, while going through School and impressing girls.Once they get married and content with their life they tend to care less about what they wear and spend little time shopping. Key attitudes and beliefs: This segment is price sensitive, they don’t care as much about what brand they wear so they will look to for the cheapest one. They also don’t like to go out shopping, so they will go to one stop shop (clothing stores) where they can buy all they need in one store. Interest in fashion: This group does not watch much fashion TV nor do they try to interact with the fashion world. Assessment: This group does not watch hardly any fashion TV and show little interest in fashion. In the end it would be smart not to target this segment.Profit Potential Analysis Rate each segment on 1-10 scale per text| Fashionistas| Planners &Shoppers| Situationalists| Basics| Market Size| 2| 7| 6| 3| Market Growth| Not applicable| Not applicable| Not applicable| Not applicable| Competitive Strength| 8| 6| 4| 2| Price Sensitivity| 8| 5| 3| 2| Production Costs| 4| 6| 6| 2 | Marketing Costs| Not applicable| Not applicable| Not applicable| Not applicable| Market Value (Sum above/4)| 5. 5| 6| 4. 75| 2. 25| Market Size:These ratings were based on the percentage of households that fall into each category. Competitive Strengt h: Competitive strength was rated on the ability of TFC to reach the segment compared to the abilities of their competitors Lifetime and CNN. The primary advantage of TFC is that the programming is focused on fashion, while the competitors offer less fashion related shows. This gives TFC a large competitive advantage with Fashionistas but puts them at a disadvantage with the Basics. The Planners & Shoppers group would also appreciate the fashion advice, while Situationalists would likely only watch programming that focused on specific fashion topics.Price Sensitivity: The Fashionista group is the least price sensitive segment due to a larger household income and an interest in fashion trends. The other three groups all expressed interest in value. The Planners and Shoppers group received a higher rating due to the fact that they enjoy shopping and stay up to date on trends. Situationalists were the third ranking group. They also enjoy shopping, but only for specific needs. The lowes t rated group was the Basics, they are very price sensitive because they want value and do not enjoy shopping. Production Costs: Production costs in this case refer to the costs of TFC advertising to each target group.The Basics group would be the most expensive to target, as they represent the greatest departure from the station’s current demographics. This group is made up of 55% men, while only 39% of the channel’s viewers are men. It would require an extensive advertising campaign to reach this group. There would not be much difference in the costs of advertising to the Planners & Shoppers and Situationalists since they have similar demographics. Production costs for the Fashionistas would likely be higher than these two groups because advertisements would have to keep up with changing fashion trends.

There are positives and negatives to every plan; we feel that the third plan shows the highest revenue increase, and delivers the best competitive advantage.The first scenario describes a plan in which The Fashion Channel would, â€Å"maintain a broad appeal to a cross segment of Fashionistas, Planners & Shoppers, and Situationalists. † (Stahl) The broad marketing plan outlined in scenario one delivers a net income of $139,908,407, and a 3% increase the margin percentage. This would be an increase of almost $19,000,000 in ad revenue per year. This plan would slightly increase the average rating that The Fashion Channel would receive and boost the average viewer number slightly, and still would not come with an incremental programming expense. This plan would however, come with a drop in the average CPM, and â€Å"along with the 10% drop in forecasted Ad sales, a broad multi-cluster strategy may not deliver an audience different enough to avoid that drop. (Stahl) Dana Wheeler had mentioned that leaving the programming unchanged along with the mo re general advertising focus could leave them vulnerable to continued penetration by â€Å"competitors in the premium segments, thus further eroding The Fashion Channel’s pricing ability. † The second scenario was to focus on the Fashionistias. This scenario would increase ad revenue per year from $230,630,400 to $322,822,560 and would increase the margin by 10%. This scenario was described as valuable because of the strong demographic. This scenario would target the smallest segment but because of the value placed on these viewers, mainly women aged between 18 and 34, would lead to a CPM of $3. 50, which is the highest of the three scenarios.The targeted segment being smaller would mean that The Fashion Channel would incur an additional programming cost per year of fifteen million dollars, along with a decrease of 0. 2% in television ratings. This scenario doesn’t increase awareness, and carries the risk of not targeting enough viewers leading to further decrea ses in overall ratings. The final scenario outlined a plan to target two segments, the Fashionistas and the Shoppers/Planners. This scenario is the one that we would recommend The Fashion Channel to take. This scenario carries an additional cost of $20,000,000 for programming to â€Å"ensure that there were viewing selections aimed at both segments. † (Stahl) This plan shows the most promising numbers of the three scenarios.Both of the targeted segments are deemed valuable to ad buyers, which increases the average CPM to $2. 50. The Fashionistas and Shoppers/Planners scenario shows an increase in ad revenue per year from $230,630,400 to $345,945,600. That is an increase of $115,000,000 in ad revenue, resulting in a $91,000,000 net income increase. The increase to the margin is significant at 11%, and could increase in the future. The average CPM may be low considering the value of the viewer’s being targeted. The repositioning in programming may help when dealing with the increasing competitive threats.

Amusement Park Physics essays

Amusement Park Physics essays Amusement parks have been around for decades and they are just as popular as they have ever been. For the most part, the physics and theories used to build these wonderful theme parks in the early years have withheld the test of time and are still exactly the same. Most people don't stop to think about how many amusement parks really rely on physics. If these thrilling rides were just constructed like you might build a tree house and physics was never applied, then the millions of people that flock to these attractions each year would simply have to find something else to waist their money and adrenaline on. First, we will look at the roller coaster. This is possibly one of the main attractions at an amusement park. What many people don't recognize is the fact that roller coasters aren't propelled by an engine. There is a good reason to back up the fact that the first hill is always the highest. Once the coaster is pulled up the hill by the crank, potential energy is at its fullest. As the coaster is making its way down the hill, that potential energy is converted into kinetic energy. At the bottom of the hill, kinetic energy is at its highest. Throughout the rest of the ride, the coaster is simply propelled by the constant conversion from potential to kinetic energy and back again. Another factor that enters into the extreme speeds that roller coaster can reach are the wheels. There are basically three types of wheels. The running wheels keep the coaster on its path along the rails. The friction wheels help to control the side to side movement of the coaster. And, the las t set of wheels helps the coaster stay planted on the rails of the track, even when inverted. The car is eventually stopped by a compressed air braking system. (Amusement Park Physics) The carousel is one of the most traditional theme park rides. At first glance, the carousel may look as though it's only a simple, graceful wheel of steel. ...
