Relapse into intimate partner violence (IPV) can potentially be predicted and counter-measures applied. This study examines the predictive validity of a violence risk assessment tool: the Police Screening Tool for Violent Crimes (PST-VC) among a sample of 65 offenders. All PST-VC assessments regarding IPV that were conducted at the Scania police department in 2010 were included in the sample. Follow-up time was 16–28 months, and all reported incidents with the same victim and suspected offender were recorded. The PST-VC demonstrated limited effect in the ability to identify high-risk offenders and predict repeat victimization. Interventions against the offender and victim protective actions were more often recommended in high-risk cases but did not lower the number of IPV relapses. The study suggests that the PST-VC is not a promising instrument.  相似文献

The career stage theory postulates that employees go through different career stages, and each career stage has different effects on various outcomes, such as job satisfaction. There has been empirical support for the career stage theory from other disciplines, but there has been limited research relating to this theory to corrections. To expand the literature, the current study examined whether different career stages were significant predictors of job satisfactions, while including the personal characteristics and the workplace place variables among Texas correctional officers. The results supported the career state theory: job satisfaction was highest during the entry stage (0–2 years), but was lowest during the second career stage (2–5 years). In career stages three (5–15 years) and four (16+ years), job satisfaction rose. Possible interventions that correctional administrators can undertake to encourage job satisfaction from their staff during the second career stage are discussed.  相似文献

Early puberty is associated with stressful family environments, early sexual intercourse, and teenage pregnancy. We examined pubertal timing and sexual debut among the 14-year-old offspring of teenage mothers. Mothers (71% Black, 29% White) were recruited as pregnant teenagers (12–18 years old). Data were collected during pregnancy and when offspring were 6, 10 and 14 years old (n = 318). Adolescents (50% male) compared the timing of their pubertal maturation to same-sex peers. There was a significant 3-way interaction effect of race, sex, and pubertal timing on sexual debut (n = 305). This effect remained significant in a model controlling for maternal age at first intercourse, substance use, exposure to trauma, authoritative parenting, and peer sexual activity (n = 255). Early maturation was associated with early sex in daughters, and may be one pathway for the inter-generational transfer of risk for teenage pregnancy among daughters of teenage mothers.  相似文献

Sexual violence is a global problem that particularly affects women and children. A retrospective analysis of 390 clinical-forensic examinations and 120 autopsies regarding injuries of the female genitalia in cases of sexual violence was performed. In the majority of cases no injuries of the female genitalia were found. Autopsy cases showed significantly more (and more serious) injuries of the genitalia than clinical forensic examinations (43 % vs. 25 %; p = 0.0004). Predominantly found were injuries of the external anogenital area, mostly tears or soft tissue lesions. In the current literature, data regarding the rate of injuries in victims of sexual violence vary strongly and their comparability is limited. Regarding the reconstruction of an offence, a forensic examination with an appropriate documentation of the injuries is evidently crucial.  相似文献

This article analyzes class actions as a technology that groups may use in their rent-seeking activity, in addition to other rent-seeking methods such as legislative investment within the political market, when they seek to achieve favorable decisions from decision-makers—courts and legislators. It claims that groups may make their choice between various rent-seeking technologies according to their sensitivity to the problem of free riding. Therefore, it analyzes the effect of the legal instruments that facilitate class action lawsuits and collective litigation in most countries upon the rent-seeking strategies of groups, as compared to rent-seeking through legislation.  相似文献

The harm caused by many acts is not certain but probabilistic. Current public enforcement of the law combines harm-based sanctions (usually in criminal law) with act-based sanctions (very common in administrative law and regulation). We propose an economic theory of the choice between harm-based and act-based sanctions in public enforcement. The efficiency of act-based versus harm-based sanctions is analyzed and a typology of the determinants is drawn up. Our model suggests that harm-based sanctions are more efficient when (1) acquiring information about the act is important, (2) engaging in harm avoidance activities is advisable, (3) judgment-proofness is not a very significant problem, (4) punishment is especially costly, (5) changes in law are expensive or difficult to negotiate and (6) on average, potential criminals are better informed than the government about losses for society. Legal policy implications are discussed.  相似文献

The nanotechnology and biotechnology “revolutions” are so-called because their enabling technological breakthroughs were not simply inventions, but discoveries of entirely new methods of inventing. We hypothesize that university participants in either or both of these areas will exhibit greater collaboration with industry than researchers in other areas. We explore this hypothesis for 454 faculty members who conducted research that was patented during the period 1994–1999. Because our data include patents, publications, and funding at the individual level, we are able to examine the industry interaction of faculty who participated in the nanotechnology and biotechnology revolutions, as well as the interaction of faculty contributing to other areas of patentable science. We examine a variety of linkages, including sponsored research, consulting, publication with firm employees and measures of the potential for cross-campus collaboration. The results are striking in that they show significant differences in collaborative behavior across patent types and across the major program areas biological sciences, physical sciences and engineering. The results are consistent with a greater degree of tacit knowledge within the new methods of inventing. We also find significant differences in the embryonic nature and importance of patents across areas.  相似文献

Globalization has led to new health challenges for the twenty-first century. These new health challenges have transnational implications and involve a large range of actors and stakeholders. National governments no longer hold the sole responsibility for the health of their people. These changes in health trends have led to the rise of global health governance as a theoretical notion for health policy making. The Southeast Asian region is particularly prone to public health threats such as emerging infectious diseases and faces future health challenges including those of noncommunicable diseases. This study looks at the potential of the Association of Southeast Asian Nations (ASEAN) as a regional organization to lead a regional dynamic for health cooperation in order to overcome these challenges. Through a comparative study with the regional mechanisms of the European Union (EU) for health cooperation, we look at how ASEAN could maximize its potential as a global health actor. Our study is based on primary research and semistructured field interviews. To illustrate our arguments, we refer to the extent of regional cooperation for health in ASEAN and the EU for (re)emerging infectious disease control and for tobacco control. We argue that regional institutions and a network of civil society organizations are crucial in relaying global initiatives, and ensuring the effective implementation of global guidelines at the national level. ASEAN’s role as a regional body for health governance will depend both on greater horizontal and vertical integration through enhanced regional mechanisms and a wider matrix of cooperation.  相似文献

Empirical evidence shows that consumers are often subject to a projection bias, such as they exaggerate the degree to which their future tastes will resemble their current ones. Such biases are particularly acute when consumers commit to a long-term contract. This paper aims at assessing the consequences of projection bias and at defining when a legal intervention is relevant. In this perspective, we compare the situation of naive and sophisticated agents, both with and without regulation regarding contract duration and early termination fees. The demand side of the market consists either of sophisticated agents, who perfectly anticipate their future willingness to pay (WTP); or of naive consumers, who exhibit a projection bias. The supply side is a monopoly offering long- and short-term contracts. Our main contribution consists in showing that naive consumers are not always worse off than sophisticated agents. The key parameter is how willingness to pay varies over time. If consumers have an increasing WTP for a given service or product, naive agents can actually be better off than sophisticated ones. We argue that naivete protects consumers against a price increase. However, naivete also leads to less exchanges on the market, thus generating a deadweight loss. Hence, the overall effect of naivete on social welfare is ambiguous. As far as public policy is concerned, we conclude that regulating contract duration is only relevant in some circumstances, depending on the market characteristics and on the bias.  相似文献
