This study examined the mediating roles of several family variables in the relation between IPV witnessing and children’s emotional and behavioral problems among 129 low-income, African American children ages 8 to 12. According to the mediational model tested, experiencing or witnessing IPV negatively impacted the following family variables: maternal psychopathology, family cohesion, and relatedness quality, which were subsequently associated with diminished child adjustment. These findings were stronger when child reports were considered and when the outcome variable was internalizing problems. Findings from this study support the value of targeting these variables in the development of culturally appropriate child witness interventions for low-income African American families. Recommendations for future interventions based on study conclusions are offered.  相似文献

Relatively few studies have assessed theoretically relevant predictors of individual’s perceptions of racial profiling by law enforcement officers. The current study addresses this limitation by drawing on theoretical frameworks highlighted in the growing body of literature examining disproportionate minority contact (DMC) with the criminal justice system. Specifically, we draw on the racial and symbolic threat perspectives with the objective of identifying theoretically relevant individual and community level predictors of perceptions of racial profiling by public and private police bodies in airports, malls, and on the roads. Results of our analysis of data on White and Black individuals nested within communities support the racial threat perspective in documenting the influence of racial heterogeneity and interracial labor market competition on perceptions of racial profiling. However, in contention to predictions derived from the symbolic threat perspective, the results fail to uncover a link between interracial socioeconomic inequality and perceptions of racial profiling by law enforcement officers. These results highlight the importance of moving beyond individual explanations of profiling and other forms of DMC and suggest community characteristics and perceptions of intergroup threat are particularly salient to understanding perceptions of race-based distinctions in formal social control.  相似文献

This paper outlines the sociodemographic, developmental, antecedent attack, attack preparation, and commission properties of 115 mass murderers between 1990 and 2014. The results indicate that mass murderer attacks are usually the culmination of a complex mix of personal, political, and social drivers that crystalize at the same time to drive the individual down the path of violent action. We specifically focus upon areas related to prior criminal engagement, leakage, and attack location familiarity. Whether the violence comes to fruition is usually a combination of the availability and vulnerability of suitable targets that suit the heady mix of personal and political grievances and the individual's capability to engage in an attack from both a psychological and technical capability standpoint. Many individual cases share a mixture of unfortunate personal life circumstances coupled with an intensification of beliefs/grievances that later developed into the idea to engage in violence.  相似文献

Research into the deposition patterns of primer gunshot residue (GSR) beyond a primary target was previously nonexistent. This study aimed to determine the deposition patterns of GSR once a bullet passed through an initial target and continued on its path into additional targets. Multiple repetitions were performed to assess the GSR deposition patterns after a bullet was shot through a closed window into either a dummy or a wall within an enclosed room. Samples were taken from both the primary and secondary target holes as well as from nontarget areas. Significant amounts of GSR were found on all samples. The results show that GSR continues to be deposited along the path of the bullet after passing through a primary glass target. These findings reiterate the lack of probative value in collecting GSR samples from gunshot victims even if they are in an enclosed area separate from the shooter.  相似文献

This article examines the implications for patient care, and for the future of rationing within the NHS, of the recent decision to permit NHS patients to supplement their care by paying for medicines — mainly expensive new cancer drugs — which are not available within the NHS. The starting point is the recommendations of the Richards' Report and their implementation through new guidance issued by the Department of Health and the National Institute for Health and Clinical Excellence. Practical challenges arise from the insistence upon the ‘separate’ delivery of self‐funded medicines, and more flexible cost‐effectiveness thresholds for end of life medicines may have repercussions for other patients. While undoubtedly part of the trend towards explicit rationing, top‐up fees might also represent a significant step towards regarding the NHS as a core, basic service. Finally, the issue of top‐up fees is located within the broader context of current cancer research priorities and persisting health inequalities.  相似文献

Abstract: Using Blood Oxygen Level Dependent (BOLD) functional MRI (fMRI) to detect deception is feasible in simple laboratory paradigms. A mock sabotage scenario was used to test whether this technology would also be effective in a scenario closer to a real‐world situation. Healthy, nonmedicated adults were recruited from the community, screened, and randomized to either a Mock‐crime group or a No‐crime group. The Mock‐crime group damaged and stole compact discs (CDs), which contained incriminating video footage, while the No‐crime group did not perform a task. The Mock‐crime group also picked up an envelope from a researcher, while the No‐crime group did not perform this task. Both groups were instructed to report that they picked up an envelope, but did not sabotage any video evidence. Participants later went to the imaging center and were scanned while being asked questions regarding the mock crime. Participants also performed a simple laboratory based fMRI deception testing (Ring‐Watch testing). The Ring‐Watch testing consisted of “stealing” either a watch or a ring. The participants were instructed to report that they stole neither object. We correctly identified deception during the Ring‐Watch testing in 25 of 36 participants (Validated Group). In this Validated Group for whom a determination was made, computer‐based scoring correctly identified nine of nine Mock‐crime participants (100% sensitivity) and five of 15 No‐crime participants (33% specificity). BOLD fMRI presently can be used to detect deception concerning past events with high sensitivity, but low specificity.  相似文献

This article extends the debate over personality disorders as dimensional or taxonic phenomena to the study of psychopathy and relates this issue to questions surrounding whether behaviors or personality traits best represent psychopathy. Proponents of dimensional measurements of psychopathy consider personality traits to be important constructs of psychopathy, whereas proponents of taxometric measurements consider behaviors to be important characteristics of psychopathy. After a brief introduction to the measurement of psychopathy, taxometric and dimensional measurement techniques are explained, their assumptions addressed, and their strengths and weaknesses discussed. Empirical evidence for each technique is then critiqued, and methodological problems are described. It is argued that methodological problems of existing studies largely preclude conclusions regarding whether psychopathy is dimensional or taxonic. Suggestions for future research are provided to address some of these methodological limitations. This review informs readers about each measurement approach and identifies problems regarding the dimensional or taxonic measurement of psychopathy.  相似文献

This case note examines the long‐standing litigation against Georgia State University in relation to the posting, by faculty and library staff, of unauthorised copies of book extracts on the University's electronic reserves and virtual learning environment. The central question in this litigation has been whether these acts of copying fall within the fair use doctrine in US copyright law. In answering this, a key question for the US courts – and one relevant to other jurisdictions with free exceptions for education, such as the UK – has been whether existing and potential licensing activity is relevant to the question of whether an exception applies. This case note discusses how market effect has been analysed in Georgia State, including the recent rejection by the Court of Appeals for the Eleventh Circuit of a strongly empirical approach to market harm.  相似文献

Two hundred prosecuting attorneys completed a survey concerning priorities in taking on animal cruelty cases and the factors that help or hinder prosecuting such cases. Respondents commented on the priority given such cases. Questions also addressed specific kinds of evidence that had been used to decide whether to take on a cruelty case and were used in court. Results showed that prosecutors most frequently relied upon “traditional” sources of evidence, including detailed medical and crime scene reports and good quality photographic evidence. Other sources of forensic evidence such as DNA, computer forensics, forensic accounting, blood, and trace evidence were rarely employed. Veterinary forensic evidence, including forensic necropsies and detailed medical reports, was viewed as an important factor by a majority of prosecutors in deciding whether to accept a case for prosecution and in achieving a successful outcome, but a need for additional training for investigators was indicated.  相似文献
