Adolescence Essays (1334 words) - Abnormal Psychology,

Adolescence Adolescence is a stage of maturation between childhood and adulthood that denotes the period from the beginning of puberty to maturity. However, many conflicting opinions are raised about weather such a stage of childhood is influenced by stress, depression, and suicide rate. Some people support the optimistic view that says that adolescence is not a period of storm and stress. Others, including me, support an opposite pessimistic view which characterizes adolescence as a period of stress and inner turmoil. Unfortunately, it has been recently proved that depression is a growing problem in today's society and a major contributing factor for a multitude of adolescent problems. This is because , as research indicates, adolescent depression is the result of mood disorders accompanying this period and the high suicide rate that is basically a result of such a depression. By analyzing depression, we will find that depression is a disease that afflicts the human psyche in such a way that the afflicted tends to act and react abnormally toward others and himself. Therefore it comes to no surprise to discover that adolescent depression is strongly linked to teen suicide. Adolescent suicide is now responsible for more deaths in youths aged 15 to 19 than cardiovascular disease or cancer (Blackman, 1995). Despite this increased suicide rate, depression in this age group is greatly underdiagnosed and leads to serious difficulties in school, work and personal adjustment which may often continue into adulthood. However, how prevalent are mood disorders in children and when should an adolescent with changes in mood be considered clinically depressed? Brown (1996) has said the reason why depression is often over looked in children and adolescents is because children are not always able to express how they feel. Sometimes the symptoms of mood disorders take on dif ferent forms in children than in adults. Adolescence is a time of emotional turmoil, mood swings, gloomy thoughts, and heightened sensitivity. It is a time of rebellion and experimentation. Blackman (1996) observed that the challenge is to identify depressive symptomatology which may be superimposed on the backdrop of a more transient, but expected, developmental storm. Therefore, diagnosis should not lay only in the physician's hands but be associated with parents, teachers and anyone who interacts with the patient on a daily basis. Unlike adult depression, symptoms of youth depression are often masked. Instead of expressing sadness, teenagers may express boredom and irritability, or may choose to engage in risky behaviors (Oster Brown, 1996; Lasko et al., 1996) and suicide (Blackman, 1995; Brown, 1996; Lasko et al., 1996; Oster Oster & Montgomery, 1996), constant boredom (Blackman,1995), disruptive behavior, peer problems, increased irritability and aggression (Brown, 1996). Blackman (1995) proposed that formal psychological testing may be helpful in comp licated presentations that do not lend themselves easily to diagnosis. For many teens, symptoms of depression are directly related to low self esteem stemming from increased emphasis on peer popularity. For other teens, depression arises from poor family relations which could include decreased family support and perceived rejection by parents (Lasko et al., 1996). Oster & Montgomery (1996) stated that when parents are struggling over marital or career problems, or are ill themselves, teens may feel the tension and try to distract their parents. This distraction could include increased disruptive behavior, self-inflicted isolation and even verbal threats of suicide. So how can the physician determine when a patient should be diagnosed as depressed or suicidal? Brown (1996) suggested the best way to diagnose is to screen out the vulnerable groups of children and adolescents for the risk factors of suicide and then refer them for treatment. Some of these risk factors include verbal signs of suicide within

Topographic Maps

Topographic Maps Topographic maps (often called topo maps for short) are large scale (often greater than 1:50,000) maps that show a wide range of human and physical features of the Earth. They are very detailed maps and are often produced on large sheets of paper. The First Topographic Map In the late 17th century, French finance minister Jean Baptiste Colbert hired surveyor, astronomer, and physician Jean Dominique Cassini for an ambitious project, the topographic mapping of France. He [Colbert] wanted the kind of maps that indicated man-made and natural features as determined by precise engineering surveys and measurements. They would portray the shapes and elevations of mountains, valleys, and plains; the network of streams and rivers; the location of cities, roads, political boundaries, and other works of man. (Wilford, 112) After a century of work by Cassini, his son, grandson, and great-grandson, France was the proud owner of a complete set of topographic maps the first country to have produced such a prize. Topographic Mapping of the United States Since the 1600s, topographic mapping has become an integral part of a countrys cartography. These maps remain among the most valuable maps for government and the public alike. In the United States, the U.S. Geological Survey (USGS) is responsible for topographic mapping. There are over 54,000 quadrangles (map sheets) that cover every inch of the United States. The USGS primary scale for mapping topographic maps is 1:24,000. This means that one inch on the map equals 24,000 inches on the ground, the equivalent of 2000 feet. These quadrangles are called 7.5 minute quadrangles because they show an area that is 7.5 minutes of longitude wide by 7.5 minutes of latitude high. These paper sheets are approximately 29 inches high and 22 inches wide. Isolines Topographic maps use a wide variety of symbols to represent human and physical features. Among the most striking are the topo maps display of the topography or terrain of the area. Contour lines are used to represent elevation by connecting points of equal elevation. These imaginary lines do a nice job of representing the terrain. As with all isolines, when contour lines lie close together, they represent a steep slope; lines far apart represent a gradual slope. Contour Intervals Each quadrangle uses a contour interval (the distance in elevation between contour lines) appropriate for that area. While flat areas may be mapped with a five-foot contour interval, rugged terrain may have a 25-foot or more contour interval. Through the use of contour lines, an experienced topographic map reader can easily visualize the direction of stream flow and the shape of the terrain. Colors Most topographic maps are produced at a large enough scale to show individual buildings and all streets in cities. In urbanized areas, larger and specific important buildings are represented in black though the urbanized area surrounding them is represented with a red shading. Some topographic maps also include features in purple. These quadrangles have been revised solely through aerial photographs and not by the typical field checking that is involved with the production of a topographic map. These revisions are shown in purple on the map and can represent newly urbanized areas, new roads, and even new lakes. Topographic maps also use standardized cartographic conventions to represent additional features such as the color blue for water and green for forests. Coordinates Several different coordinate systems are shown on topographic maps. In addition to latitude and longitude, the base coordinates for the map, these maps show UTM grids, township and range, and others. Source Campbell, John. Map Use and Analysis. 1991. Monmonier, Mark.
