CRJS478DB4 - Research Paper Example These contaminants can affect the entire results of DNA profiling and should be avoided. In regard to analysis of DNA the most significant contaminants involve cross contamination which arises from non-related samples other than the sample being tested. The effect of these contaminants is that it can skew the results of the test and give inaccurate results (Butler, 2011). Some notable court cases involving contamination of DNA include the O.J Simpson case and the Amanda Knox case. In both these cases the court struck out DNA evidence because of the possibility of the evidence being contaminated. The outcomes of these cases are favorable for contamination of DNA evidence compromises the results of the test and renders the evidence unreliable and as such should not be used to convict suspects. DNA profiling is an important aspect in the criminal justice system because it provides the courts the possibility to determine whether blood, saliva or other biological substances located at the scene of crime belong to the person accused of committing the crime. The use of DNA evidence is essential to the courts as it is an accurate method for suspect identification (Remillard, et al. 2013). Remillard, E. M., Taylor, L.

Cross-border Mobility and Immobility - Article Example Some views also opine for the debarring of the worker flow from the foreign states which enhances the competition. The second domain circumscribes the progress from different countries like sub-Saharan Africa and the Middle East infiltrating into the European culture and the views are against the mobility particularly from the Islamic countries although the nature of variation changes from country to country. Both the domain of discussion targets at the restriction mechanism of migration. However the discussion generates the significance of the regulation of immigration. An emergence of the cross border immobility is taken as the starting phase and it has been found that people remains immobile with respect to certain destinations and the preference of destinations among the people play a significant part in the mobility (Velde & Naerssen, 2000, pp. 218-219). Argument The argument stands on the premises of examining whether the borders generates incentives for the migrants to relocat e. In other words, the argument presupposes on the decision making aspects of the people in the migration procedure in association with the prime parameter being the border in this case (Velde & Naerssen, 2000, p. 219). Structure of the paper The decision making process of cross border mobility of the migrants incorporates into it the very notion of underlying uncertainty, instability as well as the precariousness affecting their mobility behavior. In order to examine the basis of the argument three components distinguishing the international migration are explained with respect to the argument in question and that is people, borders and trajectories. The people usually decide in crossing the borders or not and this specific endeavor they can remain mobile or immobile internationally. This nature depends on the various geographical borders they take into considerations. The people are also in the following specific routes for the movement from one place to the other and hence crossi ng the national borders (Velde & Naerssen, 2000, p. 219). Literatures In 1880s, Ravenstein revealed that the study of the actual and the potential migration reduces the migrants into infinitesimally small identities within the demand supply framework of the labor market. He also inferred that the wage differentials and the distance are the key variables in determining the migration decisions which later generated in the form of the famous push and pull framework. Some other theorist states that the notion of rationality does not always play in the migration decisions as in many cases it has been encountered that the migrants are guided by the asymmetric information. The concept of human capital which links the long run investment decisions also affects the migration decisions of the migrants. The transaction cost approach states that the people calculate the costs like opportunity costs, costs of adjustment to different cultures, adaptation to legal structures and so on and so forth . Stark (1982) changed the focus of the migration from the individual to the mutual dependence among the households, families and communities. Immobility is a fact which involves only a minority of
