Illegal guns circulating among high‐risk networks represent a threat to the security and well‐being of urban neighborhoods. Research findings reveal that illegal firearms are usually acquired through a variety of means, including theft and diversions from legitimate firearms commerce. Little is known, however, about the underground gun markets supplying the gang and drug networks responsible for a large share of gun violence in U.S. cities. In this article, we take a mixed‐methods approach, combining trace analyses of recovered handguns with ethnographic interviews of high‐risk gun users to develop new insights on the entry of guns into three criminal networks in Boston. We find that guns possessed by Boston gang members are of a different character compared with other crime guns; these guns are more likely to be older firearms originating from New Hampshire, Maine, and I‐95 southern states. The results of our qualitative research reveal that gang members and drug dealers pay inflated prices for handguns diverted by traffickers exploiting unregulated secondary market transactions, with significant premiums paid for high‐caliber semiautomatic pistols. Taken together, these findings provide an analytic portrait of the market for illicit guns among those most proximate to violence, yielding novel empirical, theoretical, and practical insights into the problem of criminal gun access. 相似文献

ABSTRACT One part of the massive US intelligence effort to learn about Soviet missile and space programs during the Cold War was acquiring and analyzing Soviet space debris that had returned to Earth. Equally important was retrieving US fragments that had landed in foreign nations to prevent the Soviets from recovering and exploiting them. At times bitter jurisdictional battles among the interested government agencies plagued the undertaking. Additionally the Outer Space Treaty of 1967 limited the ability to obtain foreign debris in some circumstances. Despite these problems, however, the available record shows that in many cases the United States acquired and tested important Soviet fragments and also was able to retrieve its own. 相似文献

In the aftermath of the terrorist attacks on New York City and Washington, D.C. on September 11, 2001, U.S. government and military leaders often articulated distinctly pro-American themes in their public communications. We argue that this national identity discourse was at the heart of the U.S. government's attempt to unite the American public and to mobilize support for the ensuing "war on terrorism." With this perspective, we content analyzed Time and Newsweek newsmagazines for the five weeks following September 11 to identify potential communication strategies employed by government and military leaders to promote a sense of U.S. national identity. Findings suggest (a) that government and military officials consistently emphasized American core values and themes of U.S. strength and power while simultaneously demonizing the "enemy," and (b) that journalists closely paralleled these nationalist themes in their language. 相似文献

The sociology of punishment has developed a rich understanding of the social and historical forces that have transformed American penality during the last 40 years. But whereas these social forces are not unique to the United States, their penal impact there has been disproportionately large, relative to comparable nations. To address this issue, I suggest that future research should attend more closely to the structure and operation of the penal state. I begin by distinguishing penality (the penal field) from the penal state (the governing institutions that direct and control the penal field). I then present a preliminary conceptualization of “the penal state” and discuss the relationship between the penal state and the American state more generally. 相似文献

The aim of this study is to analyze the process by which Al Qaeda has sought to co-opt essentially localized struggles in Southeast Asia into an evolving network of worldwide jihad. The article illustrates how, long before it was appropriate to speak of an entity called Al Qaeda, Islamists have been thinking transnationally since the 1980s. The argument attempts to piece together available evidence to reveal a plausible explanation of the origins, growth and direction of the main Islamist grouping in Southeast Asia, Jemaah Islamiyah, and its deepening relationship with Al Qaeda. The article suggests that the roots of a Southeast Asian terror network can be traced to two geographically separate ethno-religious struggles in the Philippines and Indonesia. The analysis demonstrates that these guerrilla groups orchestrating their distinct struggles were eventually combined through the auspices of Al Qaeda and the globalized franchising opportunities it exploited from the early 1990s.‐ 相似文献
