Purpose

To assess differences in victimization risk between African American and white, non-Latino inmates, and to estimate race group differences in the correlates of victimization.

Methods

Random samples totaling 2,403 African Americans and 3,150 whites were drawn from all state prisons in Ohio and Kentucky and all private prisons in Ohio (n = 46). Race-specific bi-level models of physical assaults and property thefts were estimated. Differences between race-specific models in the magnitude of regression coefficients for the same predictors and outcomes were compared.

Results

The odds of victimization by physical assault and by theft were significantly higher among whites compared to African Americans. Race group differences in the magnitude of several inmate level effects (e.g., age, sex, education, family status, officer “legitimacy”, custody score, visitation) were also significant, yet facility effects were similar for both groups.

Conclusions

Assessing differences in the victimization experiences of African American and white inmates is important for developing effective crime prevention strategies in prison. We examined the most comprehensive models of inmate victimization (including inmate socio-demographics, activities during confinement, perceptions of officers, facility characteristics, and officer perceptions of rule enforcement) for one of the largest samples of prisons to date.  相似文献

Vacuum metal deposition (VMD) has been previously demonstrated as an effective development technique for latent fingermarks and in some cases has been shown to enhance prints developed with cyanoacrylate (CA) (superglue) fuming. This work utilizes scanning electron microscopy (SEM) to investigate the interactions of the two development techniques when applied to latent fingermarks on low-density polyethylene. CA is shown to act principally on the eccrine deposits around sweat pores, where polymerization results in long polymer fibrils a few 100 nm in width. Subsequent VMD processing results in additional areas of development, for example, between pores. However, the primary mode of deposition of zinc is by interaction with the polymerized CA, the fibrils of which become decorated with zinc nanoparticles. Areas with limited CA deposition and no significant polymerization are also enhanced with the VMD process, resulting in increased print development.  相似文献

Objectives

To present and test an opportunity perspective on prison inmate victimization.

Methods

Stratified random samples of inmates (n 1 = 5,640) were selected from Ohio and Kentucky prisons (n 2 = 46). Bi-level models of the prevalence of assaults and thefts were estimated. Predictors included indicators of inmate routines/guardianship, target antagonism, and target vulnerability at the individual level, and several indicators of guardianship at the facility level.

Results

Assaults were more common among inmates with certain routines and characteristics that might have increased their odds of being victimized (e.g., less time spent in recreation; committed violence themselves during incarceration), and higher levels of assaults characterized environments with lower levels of guardianship (e.g., architectural designs with more “blind spots”, larger populations, and less rigorous rule enforcement as perceived by correctional officers). Similar findings emerged for thefts in addition to stronger individual level effects in prisons with weaker guardianship (e.g., ethnic group differences in the risk of theft were greater in facilities with larger populations and less rigorous rule enforcement).

Conclusions

The study produced evidence favoring a bi-level opportunity perspective of inmate victimization, with some unique differences in the relevance of particular concepts between prison and non-prison contexts.  相似文献

ABSTRACT

As government and public administration lag behind the rapid development of AI in their efforts to provide adequate governance, they need respective concepts to keep pace with this dynamic progress. The literature provides few answers to the question of how government and public administration should respond to the great challenges associated with AI and use regulation to prevent harm. This study analyzes AI challenges and former AI regulation approaches. Based on this analysis and regulation theory, an integrated AI governance framework is developed that compiles key aspects of AI governance and provides a guide for the regulatory process of AI and its application. The article concludes with theoretical implications and recommendations for public officers.  相似文献

This article ties together research on gender, income inequality, and political ideology, by exploring the effect of gender‐based earnings inequality on women's belief in a fundamental tenet of the “American Dream”—meritocracy. Focusing on gender‐based earnings inequality in women's local residential context, and drawing upon relative deprivation theory, this article argues that variation across local areas in the relative economic status of women should influence the ideological outlook of resident women. In contrast to relative deprivation theory, but consistent with rising expectations theory, I argue that ideological disillusionment should peak in contexts in which women's earnings fall closely behind men, and that ideological optimism should rebound in contexts in which women's earnings have achieved parity with that of men. Utilizing pooled survey data, I find strong evidence that individual women's belief in the American Dream varies according to whether local women's relative earnings indicate confrontation with or breaking of the “glass ceiling.”  相似文献

Brazil's successful prosecutorial civil action against polluters could be a regulatory example for the Global South. This paper analyses whether such regulation could also develop without the major political, institutional, and legal reforms that spurred it in Brazil. To do so, it analyzes China, where similar reforms have so far not occurred, but where prosecutors have recently started to initiate civil litigation against polluters. It finds that prosecutorial civil litigation in China has only a limited regulatory effect or potential. Prosecutors in China are influenced by conflicting incentive structures that reward one‐off lower level test cases with an innovation bonus, while structurally stimulating a focus on general crime fighting. Ironically, as a result of such incentives, the recent legal reform, toward providing standing for prosecutors in public interest litigation, will, in contrast to Brazil, decrease rather than increase the regulatory effect of these cases. These findings have implications for understanding how the interaction between regulatory independence, legal reform, and regime type shapes possibilities for regulatory innovation in the Global South.  相似文献

Over the last decade, Chinese citizens, judges, and prosecutors have started to take action against industrial pollution, pluralizing a regulatory landscape originally occupied by administrative agencies. Regulatory pluralism here has an authoritarian logic, occurring without the retreat of party‐state control. Under such logic, the party‐state both needs and fears new actors for their positive and negative roles in controlling risk and maintaining stability. Consequently, the regime's relation to regulatory pluralism is ambivalent, shifting between support and restriction. This prevents a development of a regulatory society that could bypass the regulatory state. Theoretically, this special edition argues for a subjective definition of regulation in a context of pluralism. Moreover, it finds that regulatory pluralism need not coincide with a decentring of regulation. Finally, it highlights how entry onto the regulatory landscape affects the non‐regulatory roles of new actors, creating unintended consequences for regulatory pluralism.  相似文献

Spectator violence has long been associated with professional football in Europe. This article examines the issue of spectator violence from a North American perspective. We begin by noting that there is little systematic research into the scope of spectator disorder in North America. Perhaps for this reason there is little consensus about the true scale of the problem on this side of the Atlantic. It does seem clear at least that there is less spectator violence associated with professional sports in North America. After reviewing a number of explanations for this finding, we conclude that it has less to do with criminal justice policies or practices, than the social context surrounding the 'spectatorship' of sports in North America. Perhaps the most important explanation for the variance in crowd behaviour concerns the demographic profiles of sports spectators in European football and North American sports.  相似文献

In the 1980s, governments around the world adopted New Public Management ideas about inserting competition into government as a way to improve the performance of public organizations. In many nations, contracting out was one method of making governments more businesslike. Yet, there have been few studies of how government contracting behaviors have changed since the early 1980s. We replicate Ferris and Graddy's classic 1986 study of local government production and sector choice to assess how public procurement has changed over the past 35 years. Our findings show that today, contracting out is more commonly used across 25 local government service areas. In contrast to the original study, much of the growth has been in government-to-government contracts. For profit firms are also winning more contracts for high transaction cost work, while nonprofits are receiving fewer government contracts in nearly every service area. Our analysis suggests that contracting out remains of the highest importance in 21st-century governance and that additional research is needed on how to manage contracts to achieve the best value.  相似文献
