There is little previous research on firearm background check applications and denials despite the potential for such research to significantly benefit policy and practice. The U.S. firearm background check system is complex with federal, state, and local laws creating a patchwork system intended to increase public safety and reduce mortality. State characteristics may play an important role in changes in application and denial rates. We examined the relationship between application and denial rates and state characteristics such as poverty, race, gender, existing firearm ownership, and population density. Multi‐level longitudinal modeling was used in an ecological study design with the state as the unit of analysis spanning a time period between 2005 and 2010, inclusive. Results indicated that application and denial rates significantly increased over time. Population density and poverty level were negatively related to application and denial rates. Firearm ownership, male population size, and percent of residents that were white were positively related to application and denial rates. Percent of African–American residents was negatively related to application rate. The importance of understanding the factors that predict firearm prevalence and the need for additional research on the denial of firearms is discussed.

Assessing law enforcement preparedness to address Internet fraud   总被引:1,自引:0,他引:1  
Recent societal concern regarding computer crime was well documented in the research literature. To date, however, modest research addressed how large, local police and sheriff's departments confront Internet fraud. Using data collected from surveys distributed to the seven hundred largest police- and sheriff's departments, the present article addresses law enforcement: (1) preparedness to enforce Internet fraud crimes; (2) perceptions of Internet fraud; (3) cooperative policing efforts; and (4) Internet fraud information dissemination practices. Among other things, results suggested that individuals within these departments believed Internet fraud was problematic, although they lacked the resources to properly address the problem. These results are discussed as they relate to the organizational design of law enforcement agencies and their potential to adapt to innovative crimes. Suggestions are offered for a more effective approach to confronting Internet fraud.  相似文献

The bulk of the research on predatory crime focuses on characteristics, profiles, and patterns of offenders. This information is important, but from the perspective of police agencies, information about the victims of predatory crimes, including victims of white-collar predatory crimes, and how they officially respond to victimization is also important. Using survey data from a random sample of 400 residents of Knox County, Tennessee, we investigated the characteristics of victims of thirteen different types of fraud. After dividing individuals into categories of non-victims, one-time victims, and repeat victims, we develop profiles of personal fraud victims by examining differences in key demographic and offense characteristics. Next, we investigate the official reporting behavior of victims. The results are instructive for police agencies as they highlight common characteristics of fraud victims and suggest methods for encouraging fraud victims to report their victimization to police.  相似文献

Franklin Delano Roosevelt was, by all accounts, a master orator. Yet success eluded him as he sought to make his fellow citizens aware of the threat Nazi Germany posed and to banish isolationists to the illegitimate margins. At other times, however, Roosevelt's campaigns to shift the underpinnings of national security debate were more effective. Notably, his definition of the adversary as the Nazi regime, rather than the German people, deeply shaped public discourse during the Second World War. This article explains the uneven results of Roosevelt's narrative projects—and those of other presidents—as a product of the intersection of the rhetorical mode he adopted and the rhetorical demands of the environment. During unsettled times, public demand for storytelling is elevated, and presidents who seize that opportunity can shape the narrative landscape and thereby policy. Presidents who fail to align their rhetoric to the moment—such as Roosevelt offering predominantly argument during these critical junctures—allow alternative narratives to proliferate. More broadly, this article offers an account of the structuring of legitimation in the national security arena.  相似文献
