The Interactionist View of Crime Essay Example | Topics and Well Written Essays - 250 words - 3

The Interactionist View of Crime - Essay Example The Interactionist view of crime explains delinquent gang behavior in a very elaborate way because it is according to this view that laws banning murder, rapes, and robbery have political undertones. This view of crime states that reality does not exist and therefore crimes are termed either as good or evil. The best example for this view of crime is people viewing some films while others cannot because they think they are not appropriate. Many people refer to criminals condemned under this view of crime as outcasts because they went against the social consensus and norms. All the three perspective views have good points but I think I would go for the conflict view of crime to explain delinquent behavior because I is important to acknowledge the differences between the lower classes compared to the upper class and this is the only perspective that can truly address the problem at hand (Siegel, 2006). First track can help reduce crime from all over the world because short-term effects of crime vary depending on age, sex and culture. Both boys and girls react differently towards crime the same way they handle breakups and heartbreaks. In Belmont for example, adolescents learn how to use guns fast because some are required to do so by their parents for the purposes of self-defense and security just like fast track would help them reduce crime as mentorship from their parents. It is without doubt that crime has spoilt adolescents and the image has stuck in the minds of many people living in America and I believe that fast track can help reduce crime if not fully eradicating it. Crime has seen many people lose their lives from gunshots and fights. According to Nicholas, a researcher who emphasizes more on the use of fast track to reduce crime, many young youths end up in crime due to lack of money and the only way they make quick money is through robbery, selling drugs and engaging in street fights, which relate to violence (Siegel, 2006). The role played by violence in the lives of adolescents in South Bronx is nothing but spoiling them and sending them to grave at an early age.

Aerodynamic Drag Reduction in Modern Consumer Automobiles Dissertation

Aerodynamic Drag Reduction in Modern Consumer Automobiles - Dissertation Example Within the course of their experiments, they uncovered many different types of aerodynamic drag on vehicles. In addressing these disparities, they came up with various modern designs to also help to reduce drag. Moreover, it can be seen that dissimilarities existed in the differences between racing car design and road car design, which had led them to explore the reasons why road vehicles did not look like racing cars. This paper will investigate other factors, such as European legislation, that influences the appearance of road vehicles. In addition, it will discuss how and why the appearance of modern cars changed in recent years through the use of texts, pictures, graphs, equations and diagrams. Moreover, the role of Bernoulli relationship on the flow around an object will be explored as well as an explanation of boundary layer properties. Finally, it will analyze flow control using passive methods like vortex generators. Clearly, researchers in their investigations had devised in novative ways to reduce the aerodynamic drag of modern road vehicles. Bettes (1982) defined aerodynamic drag as occurring when a car moved through air and the energy that opposed its direction and slowed down its movement. Another more comprehensive definition of aerodynamic drag was: †The resistance of the air to forward movement, sometimes called "aerodynamic drag". This is a factor of the shape of the vehicle, the objects which stick out (i.e., mirrors, mufflers, bumpers), the amount of turbulence at the rear of the vehicle, the nature of the vehicle's skin surface, and the amount of air going through the vehicle for cooling and ventilation. The faster you go, the greater the air friction (proportional to velocity ²). At the same time, the power to overcome such friction is proportional to velocity ³.† (www.f1technical.net/glossary/). ...

Drag and the Different Types of Aerodynamic Drag on Vehicles Bettes (1982) defined aerodynamic drag as occurring when a car moved through air and the energy that opposed its direction and slowed down its movement. Another more comprehensive definition of aerodynamic drag was: †The resistance of the air to forward movement, sometimes called "aerodynamic drag". This is a factor of the shape of the vehicle, the objects which stick out (i.e., mirrors, mufflers, bumpers), the amount of turbulence at the rear of the vehicle, the nature of the vehicle's skin surface, and the amount of air going t hrough the vehicle for cooling and ventilation. The faster you go, the greater the air friction (proportional to velocity?). At the same time, the power to overcome such friction is proportional to velocity?.† (www.f1technical.net/glossary/). Bettes (1982) examined the fuel use required to offset the aerodynamic drag of road vehicles, but it served as one of many factors affecting cars. Lift force and the side force comprised other factors as well, which were referred to in non dimensional coefficients used in a broad speed array. Moreover, these forces and their associations with their axes (pitching, yawing, and rolling) relied upon the square of the speed of the
