Competition in public administration is often advocated as a solution to bureaucrats’ corruption. However, there are no well developed analyses of how competition could succeed and the issue of its detailed design has not been carefully addressed so far. In this paper, we put forward a series of models that help understand what competition in public administration can actually accomplish. We distinguish two different shapes that corruption may take: bribery and extortion, and we demonstrate, under the usual assumption of asymmetric information as to the honesty of the bureaucrats, that while competition is effective in fighting extortion it exacerbates bribery. Given that corruption normally manifests itself simultaneously under the two different shapes, an anti-corruption policy based upon competition is bound to face a serious trade-off: trying to curb one of them through competition implies making the other worse. This result holds, with some differences, under exogenous and endogenous bureaucrats’ “honesty”. The dual aspect of corruption is probably one of the most serious—and so far largely neglected—obstacles to any effective anti-corruption policy.  相似文献

Many law enforcement agencies are currently responding to the problem of online crime by establishing proactive investigative units that track criminals on the Internet. Not only do these specialized teams face problems in the area of emerging technology, they are also faced with handling emerging legal issues. The current research examined the issue of the entrapment defense, and how previously established physical realm doctrine could be applied to the investigation of online crimes such as child pornography. Relying on previous case law it would appear that entrapment claims related to online sting operations involve consideration of: a) did the law enforcement officer continuously contact the suspect with the intention of trying to convince the individual to engage in a particular type of behavior, b) how long was the relationship between the undercover officer and the suspect, and c) how much, if any, reluctance to commit the criminal act did the suspect provide evidence of?  相似文献

This study assessed the associations of characteristics of domestic violence incidents with clinically significant levels of traumatic symptoms and behavioral problems in a socio-economically and ethnically mixed sample of 687 children participating in a community-service program for children witnessing violence. Study predictors included child/family demographic characteristics, type and chronicity of exposure, and child’s perceptions of control over the event and threat to personal safety. Outcomes consisted of traumatic symptoms and behavior problems. Results showed that perceived threat and control were associated with greater odds of clinically significant levels of several trauma symptoms (and behavior problems in the case of perceived threat) after adjusting for effects of demographic factors and violence characteristics. Child co-victimization increased odds of reaching clinically significant levels of traumatic symptoms compared to children who witnessed the event but were not victimized. Female sex and White ethnicity increased odds of specific trauma symptoms and behavior problems. Increasing age reduced odds of some trauma symptoms. Associations between predictors and one outcome measure did not generalize across the other outcome measure. Implications of study findings, and directions for future research are discussed.  相似文献

With few exceptions, prior explanations of racially disparate punishment have followed a dichotomous approach (i.e., African American versus Caucasian), due in part to the limitations of existing data. Researchers have either excluded Latino/a, defendants or treated them as a monolithic group. Consequently, there is not much on Latinos/as, whose experiences with the criminal and juvenile justice systems differ from those of African American and Caucasian. This article expands on current literature by providing a thorough overview of existing literature on Latino/as. It critiques this body of literature and lists ten common methodological flaws that may contribute to findings of equal treatment. Finally, it provides a concise summary of the main subgroups within the umbrella term ‘Latino/a’ to highlight the heterogeneity within this classification.  相似文献

Recent interest in the construct of motivation to change among male perpetrators of intimate partner violence (IPV) has led to development of two self-report measures of this construct: the University of Rhode Island Change Assessment for Domestic Violence (URICA-DV; Levesque et al. 2000) and the Safe at Home Inventory (SAH; Begun et al. 2003). We examined the internal structure of these instruments using confirmatory and exploratory factor analyses in a sample of 199 male IPV perpetrators waiting to begin court-mandated batterer intervention programs. Results indicated that the scales had adequate internal consistency. However, using confirmatory factor analyses, the hypothesized structural models of each instrument fit the data poorly. Subsequent models suggested by a series of exploratory factor analyses failed to improve model fit substantially for both scales. For the URICA-DV, a 3-factor model including items from the Precontemplation, Contemplation, and Action subscales fit the data adequately. No acceptable model fit could be found for the SAH. Intercorrelations among similar subscales across the two inventories suggested only a modest degree of intercorrelation (r’s = 0.16–0.52), and a factor structure more dependent on scale of origin than item latent content, suggesting that the scales assess different facets of the readiness to change construct. These results suggest that before the stages of change construct can be fully applied to the IPV area, more research and evaluation are needed on how to accurately assess abuser readiness to change.  相似文献

Over the last several decades, numerous civil wars have ended as a consequence of negotiated settlements. Following many of these settlements, rebel groups have made the transition to political party and competed in democratic elections. In this paper, I assess the legacy of civil war on the performance of rebel groups as political parties. I argue that the ability of rebels to capture and control territory and their use of violence against the civilian population are two key factors explaining the performance of rebels as political parties. I test these hypotheses against the case of the Farabundo Martí National Liberation Front (FMLN) in El Salvador using one-way ANOVA and multivariate regression analyses. In analyzing the FMLN’s performance in the 1994 “elections of the century,” I find that, as a political party, the FMLN benefited both from the state’s violently disproportionate response and its ability to hold territory during the war.  相似文献
