Drawing on Connell’s (Gender and power: Society, the person and sexual politics. California: Stanford University Press, 1987; Masculinities. Berkeley, CA: University of California Press, 1995) model of gender relations, this paper examines patterns of intimate partner violence among women who have recently left an abusive partner. In so doing, we attempt to better understand the social structural factors that shape the relations of power and control in intimate violent heterosexual unions. The data come from the first wave of a longitudinal prospective survey of 309 women who had left an abusive partner in the previous 3 years. Our data suggest that structured relations of inequality, namely relations of production, power and cathexis, shape women’s risk of abuse and harassment after leaving, and do so in ways that shape relations of coercive control. These results have implications for understanding the social context within which male violence against women occurs, and how this context constrains and/or enables women’s strategies for leaving and safety. This research was funded by the Canadian Institutes of Health Research (CIHR) New Emerging Team Grant #106054 and Institute of Gender and Health Operating Grant #15156 (Marilyn Ford-Gilboe, Principal Investigator).

Police complaints are a developing area of European human rights law and criminal justice policy. In response to the risk of cultures of police impunity emerging in some European states the Council of Europe Commissioner for Human Rights launched a police complaints initiative in 2008. Written by the consultant to the Commissioner this paper examines his recently published Opinion concerning independent and effective determination of complaints against the police. Firstly, an overview is presented of the different types of complaints mechanism currently operating across Europe. This is followed by an outline of the five police complaints principles developed in the jurisprudence of European Court of Human Rights and explanation of the two-tiered citizen oversight approach advocated in the Commissioner's Opinion. The paper concludes with a discussion of the importance of the principles as a means for ensuring that every police complaint is handled appropriately and proportionately.  相似文献

In the absence of a national carbon price, the federal Corporate Average Fuel Economy standards and the related greenhouse gas emissions (GHG) standards are the primary mechanisms through which the U.S. reduces transportation GHG emissions. In 2012, these standards were set to rise for light‐duty vehicles between 2017 and 2025, eventually achieving a target of 54.5 miles per gallon in 2025. Since 2012, conditions have changed: forecasts of future gasoline prices have dropped dramatically, consumers have demanded larger vehicles, and the cost of compliance appears to be larger than previously thought. In this article, we analyze the possible macroeconomic effects of the standards with both 2012 inputs and updated inputs to reflect these new market developments. The results reveal that the short‐term effects of the federal standards will be negative, but the long‐term effects will be positive, using both 2012 and updated inputs. The transition from annual negative employment impacts to positive impacts occurs between 2023 and 2026, depending on which set of assumptions are used. Possible revisions to the standards that freeze them at 2020 levels or decrease their stringency reduce short‐term negative impacts but also reduce long‐term positive impacts. We conclude with a discussion of policy implications as they relate to the current energy and climate policy conditions.  相似文献

In many American states, public defense is provided at the county rather than state level (Langton & Farole 2009 ). Local governments have discretion over implementing and funding the right to counsel, resulting in considerable variability in programs and funding levels. Placing this issue in the theoretical context of redistributive policies and politics, we investigate decisions on funding this service across upstate New York counties. Using as a point of departure Paul Peterson's classic explication of community politics, we first model variation in funding as a function of counties' fiscal capacity, need for services, and costs of supplying legal representation. We also test Peterson's prediction that local political factors will play little if any role in budget decisions. Second, through interviews with program administrators we explore the characters of twelve defender programs in which expenditures departed from the model's predictions. We find that three factors—which we term “influence,” “infrastructure,” and “ideas"”—also vary directly with levels of funding. We conclude with a discussion of the implications of these findings for theoretical thinking about due process policies and local politics, and for policy debate over how best to ensure adequate counsel in criminal court.  相似文献

Objectives

Decades of empirical research demonstrate that crime is concentrated at a range of spatial scales, including street segments. Further, the degree of clustering at particular geographic units remains noticeably stable and consistent; a finding that Weisburd (Criminology 53:133–157, 2015) has recently termed the ‘law of crime concentration at places’. Such findings suggest that the future locations of crime should—to some extent at least—be predictable. To date, methods of forecasting where crime is most likely to next occur have focused either on area-level or grid-based predictions. No studies of which we are aware have developed and tested the accuracy of methods for predicting the future risk of crime at the street segment level. This is surprising given that it is at this level of place that many crimes are committed and policing resources are deployed.

Methods

Using data for property crimes for a large UK metropolitan police force area, we introduce and calibrate a network-based version of prospective crime mapping [e.g. Bowers et al. (Br J Criminol 44:641–658, 2004)], and compare its performance against grid-based alternatives. We also examine how measures of predictive accuracy can be translated to the network context, and show how differences in performance between the two cases can be quantified and tested.

Results

Findings demonstrate that the calibrated network-based model substantially outperforms a grid-based alternative in terms of predictive accuracy, with, for example, approximately 20 % more crime identified at a coverage level of 5 %. The improvement in accuracy is highly statistically significant at all coverage levels tested (from 1 to 10 %).

Conclusions

This study suggests that, for property crime at least, network-based methods of crime forecasting are likely to outperform grid-based alternatives, and hence should be used in operational policing. More sophisticated variations of the model tested are possible and should be developed and tested in future research.

This study examined the relationship between childhood exposure to parental violence and adult psychological functioning in a sample of predominantly Mexican American participants. Questionnaires assessing childhood maltreatment, family environment, and current psychological symptomatology were completed by 142 female undergraduates. Findings revealed that witnessing parental violence in childhood was associated with depressive symptoms, low self-esteem, and trauma symptoms in adulthood, even after controlling for child physical and sexual abuse. However, in subsequent analyses, also controlling for levels of nonphysical family conflict, previous associations between exposure to parental violence and adult symptomatology were reduced, such that trauma-related symptoms remained the sole outcome still predicted by a history of witnessing parental violence. Implications of these findings, issues related to the use of statistical control procedures in abuse effects research, and directions for future investigation are discussed.  相似文献

The practicing Forensic Pathologist is likely to encounter case material in which either the cause of death or a major contribution to the cause of death is underlying damage to or disease of the central nervous system. While it is good practice in many instances to have a working relationship with a Department of Neuropathology, from which advice and practical help can be sought, there may be instances when the Forensic Pathologist needs to proceed on a basis of a working knowledge of Forensic Neuropathology up to and including how to examine the specimen and take tissue blocks for processing and subsequent histological examination. Some of the more common conditions of the central nervous system such as damage consequent to hypoxia-ischaemia, hypoglycemia and epilepsy, the encephalopathies associated with altered sodium concentration, deficiency due to Vitamin B(1) and various neurodegenerative diseases that manifest as dementia and include Alzheimer's disease, cortical Lewy body disease and the prion disorders, are outlined in this article.  相似文献
