Homeland Security of the USA - Term Paper Example One of the initial challenges that faced the Department of Homeland Security (DHS) in the days immediately following 9/11 was to identify the nature of the terrorist threat. Suddenly, everything became a target and scores of known terrorist groups became potential enemies threatening imminent attack. Nuclear generating plants, chemical industries, water systems, the electrical grid, the food supply, and the information network all have value as a potential terrorist target. In general, terrorists will target "high-value symbolic targets" such as the world trade center, "high-value human targets with the goal of assassination", and "deliberately lethal attacks specifically targeting the public" (Hoffman, 2006, p.167). Delivery may come from airplanes, vehicular bombs, planted explosives with a remote control detonator, or individuals carrying a bomb in a vest or backpack designed for manual detonation (Hoffman, 2006, p.166). The device may be a weapon of mass destruction, nuclear, bio logical, or chemical. This illustrates the comprehensive concerns that security had to focus on and attempt to reduce to a workable security policy. Over time, security agencies have been able to make certain facilities more secure, such as airports, but have also been met with some resistance in other industrial settings. One of the important trends that has characterized the face of foreign terrorism in the past 20 years has been the increasing role that private groups, rather than governments, have played (Pillar, 2001, p.ix). Many of the terrorist groups that have their origin in the Middle East are privately funded and have no direct governmental involvement, instead drawing their recruitment and support from the religious aspect of their cause. This motivational factor has become more pronounced in the post Cold War era, as ideology became less important and the preponderance of terrorist acts began to have a more significant

Economics - Essay Example However, the firms often prefer to use machines instead of human labour as they believe that the work can be done more efficiently as compared to the human labour. The researcher through this paper would aim to discuss about the concept of diminishing marginal returns to workers. This paper would offer the researcher a scope to discuss about the employment practices using the concepts of Economics. Law of diminishing return states that in case if equal quantities of one variable factor are increased, whereas, the other factor remains constant, there is a point in the economy beyond which if an extra unit of the variable factor added leads to diminishing return and fall in marginal physical product (Black and Lynch, 2001). The main reason behind this is that as one of the factors is held fixed and the other factor is increased, the proportions of the factors change. As the proportion of variable factor increases, the factor proportions become appropriate for carrying out the production within the economy and the marginal product increases. However, the researcher says that after a certain level, the production system becomes too much crowded with variable inputs and the factor proportions cannot be utilised for the production (Edvinsson, 2002). According to a researcher, an increase in proportions of the labour as well as the capital within the agricultural land for cultivation raises the output depending on the amount of input within the production process (Black and Lynch, 2001). However, in the agricultural process there are changes that may arise due to improvement in technology as well as the factor proportions. Technology within the agricultural field deals with the use of new and improved variety of crops for production and also the use of better quality fertilizers for proper cultivation. The law of diminishing returns is also referred to as the law of variable proportions within the economy (Lopez, Vaya and Artis, 2004). According to another researcher
