Community Policing in Extremely Depressed Areas Essay -- Policing Hot

To residents of the suburbs, all economically distressed districts of the city may seem dangerous and threatening, however, to residents of these poor districts, it is just home. The local residents know the truly crime-ridden areas of each district. This essay will refer to these crime-ridden areas within poor communities as "hot spots" or "skid-row". Skid-row is generally an area of the economically distressed community that is plagued with vagrants, criminals, drug abusers and other individuals thought to be of exile from normal society (Bittner, 1967). This is an area where law abiding, poor citizens do not wish to venture (Bittner, 1967). Due to this stigma, skid-row is an area that is patrolled by police, who generally take on the role of a peacekeeper. Their role of peacekeeper is driven by their ability to apply a great deal of discretion in their law enforcement duties, as well as their need to contain the criminal activities specifically found in the skid-row are as. The police are given a great deal of discretion in performing their duties. They make decisions on a daily basis, whether to arrest an individual on more minor offenses, or to give an individual a warning and promise to â€Å"keep an eye† on the person or area in the future (Bittner, 1967). When the officers make such decisions to not effect an arrest for a violation, they are essentially taking on the role of peacekeeper. The officer is trying to influence the actions of individuals, such as those in skid-row areas, to not commit further crimes (Bittner, 1967). The discretion not to arrest for certain crimes is likewise an attempt to contain the criminal activities to a specific area, as to not affect others (Bittner, 1967).

The Integumentary System

5 The Integumentary System FOCUS: The integumentary system consists of the skin, hair, nails, and a variety of glands. The epidermis of the skin provides protection against abrasion, ultraviolet light, and water loss, and produces vitamin D. The dermis provides structural strength and contains blood vessels involved in temperature regulation. The skin is attached to underlying tissue by the hypodermis, which is a major site of fat storage. CONTENT LEARNING ACTIVITY Hypodermis The hypodermis is not part of the integumentary system.

Laurel Thatcher Ulrich, Good Wives Image and Reality in the Lives of Women in Northern New England 1650-1750 (New York: Oxford University Press, 1983) The novel Good Wives is a study of the many roles women play in Northern New England from 1650-1750. The book is split into three sections; all named after biblical females who portrayed idealized feminine traits within New England society. The first part is named Bathsheba, which shows and explains the responsibilities and possibilities women had as a housewife focusing on economic life. The second part is dedicated to Eve. It includes not only the role of being a mother, but also the complexities of sexual life and childbirth in New England. In the third section, Jael, Ulrich explains†¦show more content†¦Ulrich describes three women’s lives including: one living on a farm, one living in a coastal town, and one living near the frontier. All three of the women’s housework was essential for the household’s survival. In order to be a good deputy husband woman must bear male duties. This could mean planting corn as a farmer’s wife or winding quills for the loom as a weaver’s wife. They also expanded responsibility for the external affairs of the family acting as not just a helper but a potential surrogate. A friendly neighbor sustained the community of women by embracing the obligations of charity, helpfulness, and sociability. Women were expected to gossip, trade, assist in childbirth, share tools and lore, and watch for cases of abuse. Throughout Eve, part two of the book, Ulrich focuses on how to be a good wife involving sex and reproduction. As a consort, a woman must be very involved in their husband’s lives. For happier couples this brought upon a harmonized marriage both spiritually and sexually, but for less happier marriages major clashes could occur. However as Christians and wives, women were expected to act secondary to their husbands. Some marriages w ere closer to equality than others, but it was challenging to achieve this balance. Ulrich quotes William Secker in his explanation of a husband and wife’s relationship in Colonial New England. â€Å"A husband a wife, he wrote, were like two instruments making music, two streams in one current, aShow MoreRelatedBook Review : A Review Of A Book Review1431 Words   |  6 Pages Book reviews are just that: a review of a book.
