The Dark Side of Illegal Immigration: Cause for National Concern

The difficulty of policing a complex border like that between the United States and Mexico, specifically stemming the flow of illegal drugs and immigration, demonstrates, according to Peter Andreas's insightful and pathbreaking analysis, the challenges associated with globalization, diminished sovereignty, and economic integration between developed and developing economies. In fact, as he notes, intensifying law enforcement on the U.S.-Mexico border has had several unintended consequences, including enhancing the incentive and thus the flow of illegal drugs and migrants, which, in turn, create obstacles to the expansion of legal flows. Throughout the book an implicit question emerges: How do you balance the positive gains from globalization with the negative or dark side effects of free trade, that is, drug trafficking and illegal immigration? Taking the dilemma further, how can states in a global, borderless economy promote two contradictory policies simultaneously: strong prohibitionist, law-enforcement policies to enforce state sovereignty and economic neoliberalism and integration?

Extrinsic gettering of Cu on near-surface dislocations in Si has been the topic of recent investigation. It was shown that the Cu precipitated hetergeneously on dislocations as Cu silicide along with voids, and also with a secondary planar precipitate of unknown composition. Here we report the results of investigations of the sense of the strain fields about the large (~100 nm) silicide precipitates, and further analysis of the small (~10-20 nm) planar precipitates.Numerous dark field images were analyzed in accordance with Ashby and Brown's criteria for determining the sense of the strain fields about precipitates. While the situation is complicated by the presence of dislocations and secondary precipitates, micrographs like those shown in Fig. 1(a) and 1(b) tend to show anomalously wide strain fields with the dark side on the side of negative g, indicating the strain fields about the silicide precipitates are vacancy in nature. This is in conflict with information reported on the η'' phase (the Cu silicide phase presumed to precipitate within the bulk) whose interstitial strain field is considered responsible for the interstitial Si atoms which cause the bounding dislocation to expand during star colony growth.
