In the limited research on the origins of sanction threat perceptions, researchers have focused on either the effects of actively engaging in crime or the effects of formal sanctioning but rarely on both (i.e., the arrest ratio or the number of arrests relative to the number of crimes committed). This article extends this line of research by using a sample of Colorado inmates and measures arrest ratios and sanction perceptions for eight different crime types. Analyses reveal that the offenders report both significant experiential and arrest ratio effects. Theoretical and policy implications, limitations, and directions for future research are outlined.  相似文献

Many studies show that democracy promotes freer trade. However, because they typically focus on “at-the-border” barriers such as tariffs, we know little about democracy’s effects on “behind-the-border” barriers such as discrimination in government procurement. We address this question by asking how democracy affects governments’ incentives to discriminate against foreigners when buying goods and services. We argue that “buy national” policies have unclear costs and are harder to attack than policies that visibly interfere with consumers’ ability to buy foreign goods. This makes such provisions more attractive than tariffs to democratic leaders seeking reelection. We thus hypothesize that democracy leads to lower tariffs but to greater discrimination in public procurement. We support this hypothesis with an analysis of procurement and imports in 138 countries from 1990 to 2008. Our results imply that a full understanding of the democracy–trade policy relationship requires attention to increasingly prominent behind-the-border barriers to trade.  相似文献

One of the most influential cases in corporate governance is In re Caremark International Inc. Derivative Litigation (Caremark). In 1996, Caremark imposed a novel duty on boards of directors to make a good faith attempt to implement and exercise oversight over obligations leading to liability. Breach of this minimal duty has been difficult for plaintiffs to plead and prove, and the case law is littered with dismissed Caremark lawsuits. As Caremark's reign reaches a quarter‐century, however, its duties are primed to evolve. Two cases, Marchand v. Barnhill and In re Clovis Oncology, Inc. Derivative Litigation, took the rare step of allowing Caremark claims to survive motions to dismiss. These cases signal a new understanding of Caremark obligating boards not merely to attempt oversight, but to ensure proactively that such oversight is effective. This subtle but significant change in board duties is one to which the academic literature should respond. This article first reviews the Marchand and Clovis cases and argues that these cases hold significance for the future of Caremark claims. Second, this article studies client advisories from law firms and other sources that evaluate the Clovis and Marchand cases. It finds that while these advisories offer useful tactical responses, they lack strategic advice that would benefit boards over the long term. Filling the gap, this article presents long‐term strategic advice for boards not only to meet Caremark duties but also to thrive as exemplars of good governance and ethical leadership for the next twenty‐five years.  相似文献

ABSTRACT

This article presents findings from an assessment of the immediate behavioural impact of the ‘Verbal Judo’ de-escalation training program, delivered to officers in a Canadian police service in 2017, and represents the first evaluation of Verbal Judo. The evaluation utilized systematic observations of officers in videotaped simulations, comparing a baseline group of officers to officers trained in Verbal Judo. The study found that five of 15 coded behaviours were impacted at a statistically significant level in the hypothesized direction, and these tended to be simpler behaviours encouraged by the training (such as identifying oneself or providing a reason for contact), while more complex behaviours (such as empathizing with the subject) were not impacted. The evaluation also found that likelihood of utilizing de-escalation skills decreased as an officer’s years of experience increased. The paper closes by outlining the implications of these findings for de-escalation training, and elaborates the main limitations of the study.  相似文献

Seventy percent of Americans identify as middle class, but one in three middle‐income households do not earn enough to support their family at the most basic level, and four in five do not earn enough to afford a sustainable budget. This incongruity explains the increasing frustration of many workers. Yet official government measures do not capture this reality, and as a result, policy makers continue to create economic policies that perpetuate the structural mismatch between wages and costs. This Viewpoint essay addresses these shortcomings. After reviewing alternatives to the federal poverty level, it argues that the most realistic and accurate floor to the middle class is the ALICE (Asset Limited, Income Constrained, Employed) Household Survival Budget. The essay then turns to policies that help realign wages and cost of living and presents initiatives that are being implemented in states across the country. Four policy areas would enable more workers to support their families and fulfill the promise of being middle class in America: meaningful work with stable and sufficient wages, upskilling and digital retooling, fiscal cushion for periods of financial instability, and affordable credit.  相似文献

Housing insecurity is a known threat to child health understanding predictors of housing insecurity can help inform policies to protect the health of young children in low-income households. This study sheds light on the relationship between housing insecurity and availability of housing that is affordable to low-income households.

We developed a county-level index of availability of subsidized housing needed to meet the demand of low-income households. Our results estimate that if subsidized units are made available to an additional 5% of the eligible population, the odds of overcrowding decrease by 26% and the odds of families making multiple moves decrease by 31%. Both of these are known predictors of poor child health outcomes. Thus, these results suggest that state and federal investments in expanding the stock of subsidized housing could reduce housing insecurity and thereby also improve the health and well-being of young children, including their families' food security status.  相似文献
