Puritan ideals in colonial America reflected the cultural attitude and Essay

Puritan ideals in colonial America reflected the cultural attitude and defined the role of women in their society - Essay Example Choosing to be a single woman was considered by the Puritans to be disregarding ‘God’s will.’ These women were looked upon suspiciously and this choice heightened the chance that they would be accused of being a witch. This discussion will examine the role of women in colonial America and how the religious Puritanical system of the time defined women’s rights and duties within that society. Puritan women were prevented from owning property; they could not negotiate their own contracts or even keep any of their own wages. â€Å"Before the middle of the nineteenth century, the property rights of American married women followed the dictates of common law, under which everything a woman owned became her husband’s property upon her marriage† (â€Å"Married Women’s Property Acts†, n.d.). These restrictions on what a woman could do or own were partly due to the fact that most women were not considered intelligent enough to consider all the consequences involved in managing business or political situations. Women also played the subordinate role in defining the family’s religious beliefs. The observed religious traditions that guided the patriarchal family order allowed wives only a small authoritative role within the family unit. For instance, mothers were trusted and expected to pass along the teachings of the Puritans and Christianity to the children. Husbands could, and often did, entrust their wives to handle various legal and financial matters of the household or family farm but the extent of power the wife possessed always remained at her husband’s discretion. Wives that happily accepted their role and conformed to Puritan societal standards were openly referred to and addressed as ‘goodwife.’ However, the authoritative figure in the family and throughout all facets of Puritan society was clearly the man. The only role that wives served in the male dominated public psyche

Principles Of Management - Essay Example For effectiveness in the performance of any business enterprise, therefore, the management of the organization must devise a mechanism for influencing the resources of the company in a proper manner to enable it achieves its objectives (Yeoh & Koronios, 2010). Effective management is a significant component for achievement of the optimum productivity of an organization. Using an appropriate management and leadership style, the top, and the middle managers in an organization can shape both the internal and the external environment of the organization to ensure improvement in productivity within the organization. Motivation of the employees is one aspect of ensuring proper management of the internal environment of the organization, while provision of the essential social services is a responsibility of an organization to ensure appropriate cooperation and collaboration with the external environment of the organization. Management in an organization draws from a multivariate of principles and styles, thus to understand the nature of management in an organization, this paper will analyses management through a discussion on the significance of management duties, the importance of team management and communication, effective leadership as well as the ethical factors influencing effective management in an organization (Walker, 2004). The management functions in an organization are geared towards coordination of the efforts of the employees towards the meeting of the objectives of the organization. The coordination purposes are done using available resources in the organization to ensure efficiency and effectiveness in the utilization of the resources to have an optimum output. The management functions in an organization thus include planning, organizing, staffing, directing and controlling the endeavors of the organization.

Supply and Demand Simulation Essay Example for Free

Supply and Demand Simulation Essay Supply and demand is the common sense principle which defines the generally observed relationship between demand, supply and prices: as demand increases the price goes up which attracts new suppliers who increase the supply bringing the price back to normal (Law of Supply and Demand, 2010). A surplus in the market exerts a downward pressure on price while a shortage in the market exerts an upward pressure on price. In the supply and demand simulation Goodlife has control of the apartment rental community is Atlantis. In the first year Goodlife wants to bring down the vacancy rate to about 15 percent while maximizing revenue. Goodlife must lower the cost of rent in order to lower the vacancy rate but they have to make sure they don’t lower it too much or they will decrease their revenue so they must find at what rental rate they will lower vacancy but no lose revenue. As the years go by several things affect the supply and demand of the Goodlife Company, population increase, individuals wanting long-term housing and a price ceiling. Shifts in supply and demand affect decision making by causing the company to look at how to get the greatest revenue with the changes. The supply and demand simulation went over several key points that were also part of our textbook reading such as total revenue and demand, individual and market demand, cross price elasticity and shifting supply and demand. Total revenue and demand is the ability for a company to tell whether the total revenue will go up or down when they raise or lower their prices (Colander, 2008). Individual and market demand refers to how individuals may stop buying a product due to a slight rise in cost, the market demand is influenced both by how many people drop out totally and by how much an existing consumer marginally changes his or her quantity demanded (Colander, 2008). Cross price elasticity of demand is when the price of a product goes up and it positively impacts the demand of another product. Shifting supply and demand is the ability of the company to shift supply to meet demand and maintain equilibrium. At Regence BlueCross BlueShield supply and demand affects the cost of premiums as well as the type of benefits available on plans. It is important in healthcare to figure out which benefits are sought after and what it will cost to cover those benefits, by slimming down on the benefits that are used less then they can provide benefits that individuals want at a lower cost than if they supply all benefits. One example of this is putting limitations of such benefits as chiropractic or physical therapy while increasing the benefits for preventive care. Price elasticity of demand affects the decision making of the consumer and of the organization by changing the amount of a product available as well as the price of the product. Consumers will switch products if they are unable to find the product easily or if the price is higher than a similar product. Organizations must continue to shift the supply and price of a product in order to stay competitive and still make revenue. In the simulation I learned how to maintain equilibrium with supply, demand and price while maintaining company revenue at the highest rate. Goodlife must keep changing the availability and price of the apartments in order to keep up with supply and demand and maintain revenue, one way they did this is by turning some of their apartments into condos this decreased the number of apartments available but brought in revenue in a different manner.

The Tragedy of Jean Rhys Wide Sargasso Sea Essay -- Wide Sargasso Sea

The Tragedy of Wide Sargasso Sea  Ã‚   In Jean Rhys' novel Wide Sargasso Sea, whether Antoinette Cosway really goes mad in the end is debatable. Nevertheless, it is clear that her life is tragic. The tragedy comes from her numerous pursuits for love and a sense of belonging, and her failure at each and every one of these attempts. As a child Antoinette, is deprived of parental love. Her father is a drunkard and has many mistresses and illegitimate children. According to Daniel Cosway's account, old Cosway is cruel to his own son. Yet even if Daniel was not really a Cosway, and his descriptions were made out of spite, or if old Cosway had cared any more for his legitimate children than his bastard ones, his alcoholism is real, and thus he could not have been a loving father to Antoinette. Her mother, Annette, does not show much motherly affection to her either. Antoinette needs and wants her mother's love, but Annette is indifferent to her. Once, Antoinette sees her mother frown, and tries to smooth the frown out with her hand, But she pushed me away, not roughly but calmly, coldly, without a word, as if she had decided once and for all that I was useless to her. She wanted to sit with Pierre or walk where she pleased without being pestered, she wanted peace and quiet.†¦. 'Oh, let me alone,' she would say, 'let me alone' (13; part 1). One night, when Antoinette has had a nightmare, she awakens to see her mother at her bed. This makes her feel safe, but even then her mother has not come to show concern for her, but to look after Pierre, whom is frightened by her noise. When her needs for love and belonging are neglected by her parents, Antoinette seeks to fulfill them elsewhere. She seeks love from a newly foun... ...r her, if there has ever been any, is completely gone, andall that is left is destructive hatred: If I was bound for hell let it be hell. No more false heavens. No more damned music. You hate me and I hate you. We'll see who hates best. But first, first I will destroy your hatred. Now my hate is colder, stronger, and you'll have no hate to warm yourself. You will have nothing (110; part 2). He thus murders her last hope for love and safety, and brings her to England to be locked away in his attic. This is her second dislocation, this time not only removed from her own familiar world, but completely isolated from the entire world. Here her tragedy is complete, for her heart and soul are killed, and she is but a ghost, with "nothing left but hopelessness" (110; part 2). Work Cited Rhys, Jean. Wide Sargasso Sea. Ed. Angela Smith. London: Penguin, 1997.

Allegories in Dr. Jekyll and Mr. Hyde

Allegories in The Strange Case of Dr. Jekyll and Mr. Hyde The novel The Strange Case of Dr. Jekyll and Mr. Hyde has many allegories within. An allegory is a symbol with a deeper meaning. In The Strange Case of Dr. Jekyll and Mr. Hyde, there are many allegories. First, there is the religious allegory of the devil and the lower self as well as the â€Å"hiding† aspect of Hyde. Hyde is also an allegory of human character in general. The city of London, and all of its descriptions written by Robert Lewis Stevenson, is filled with allegories. First, Hyde is a complex allegory because it is arguable what exactly Hyde is supposed to represent. Hyde could be an allegory of the devil himself. Hyde could be a demon inside of Jekyll, sort of like in the Exorcist, that needs to come out but eventually become uncontrollable. Although Dr. Jekyll is described as a nice man who has many friends, but he losses them all when he drinks the potion to become Hyde. Hyde could just be an allegory for a literal part of Dr. Jekyll, which is Stevenson’s statement of saying that every person holds a â€Å"lower self,† that just wait for an opportunity to reveal evil. Also one of the most famous quotes from The Strange Case of Dr. Jekyll and Mr. Hyde, is â€Å"If he shall be Mr. Hide than I shall be Mr. Seek. † This could also mean that Hyde is just a part of Jekyll’s soul that literally hides within. Lastly, Hyde could be an allegory of human character itself. Hyde could be an allegory of the capability that everyone has within. However some people never reveal this capability, but for others, like drug users, it is easier for the evilness to come out. London is also an allegory. Mr. Hyde lives in SoHo, which is described as dark, dingy, and filled with the filth of London, which is why it makes sense that Hyde lives there of all places. SoHo is supposed to represent the capability of evil, and where it is grown. In Victorian England, the poorest of the poor lived in awful slums, some had no choice but to live a life of crime and evil, just to escape their reality. On the other hand, Dr. Jekyll lives in a distinguished and posh neighborhood. This is an allegory for Jekyll’s character, as he is a nice man. However, in Victorian England, many bad things went on behind these closed doors, which is true for Dr. Jekyll. The door in the first chapter is an allegory, as well as all the passageways described, like the one to the laboratory. These passageways and doors are places in-between worlds where most of the events in the novel takes place. The in-between of the worlds is like Dr. Jekyll. He is not a good man, nor is he evil. Jekyll is complex, and struggles with the evil part of his personality. Allegories are abundant in the novel, The Strange Case of Dr. Jekyll and Mr. Hyde.

Historic Place of the Slaughters - 676 Words

In the 1560s the ownership of the Florida Peninsula was hotly contested. The French had preemptively built a small fort, Fort Caroline, near what would become Jacksonville, Florida. In 1565 the Spanish marched from St. Augustine and took this small fort, slaughtering some 200 people. Then, they chased down the remaining French Huguenots near a small inlet. Believing that his men would be well treated, the leader surrendered to the Spanish. The Spanish slaughtered them to the last man in an act that horrified the people of the age. Thus this beautiful location became known as Matanzas or Place of the Slaughters. Fort Matanzas was finished by the Spanish in 1742. It was meant to guard Matanzas Inlet, the southern end of Matanzas River. The Spanish were worried the river would serve as a back door to the city of St. Augustine. They built it of coquina shellstone, naturally abundant in the area. The fort is a smaller square style with walls 50 foot long on each side and a 30 foot tall high tower. On the right hand wall of the fort a small tower overhangs the wall. This was where the sentries were posted. The fort was armed with five cannon aimed at the inlet and manned by one officer, four infantrymen and two gunners. The fort was only involved in one skirmish in which it successfully drove off a British fleet. By 1821, the fort was unlivable. Restorations began in 1916. By 1924 the fort was stabilized and it was given National Monument status. The National Park ServiceShow MoreRelatedThe Issue Of Horse Slaughter1656 Words   |  7 Pagesthan a tool.
