The identification of potential child maltreatment using reliable and valid screening instruments is of particular importance in high risk populations. The current study investigates the psychometric properties of the Brief Child Abuse Potential (BCAP) Inventory in mothers enrolled in opioid substitution therapy. The BCAP Risk Abuse scale had strong internal reliability. Comparisons between valid and invalid protocols (≥ 4 on the Lie scale, > 1 Random Responding) failed to find systematic differences across most variables although those with a faking good profile had significantly lower scores on psychological well being. A six-factor solution was obtained and was conceptually strong. Subsequent analyses suggested Rigidity may be an independent subscale that needs further investigation. These results add further evidence for the potential utility of the BCAP as a measure of child abuse potential. Replication studies are needed to ascertain whether the subscales derived have convergent and predictive utility. 相似文献

We employ a rational choice framework to understand the conditions under which sex traffickers allow their victims access to telecommunications devices while under their control. We posit that sex traffickers are rational actors who make calculated decisions regarding whether to allow their victims access to the Internet and cell phones. We hypothesize that sex traffickers allow younger victims and those they did not defraud in the recruitment process greater access to telecommunications devices because these decisions maximize their payoffs with minimal risk. However, we hypothesize that younger victims’ access to telecommunications devices is conditional on whether they have been defrauded in recruitment. In order to test these hypotheses, we deployed a survey to 115 victims of sex trafficking in the United States to learn about how they were recruited by their sex trafficker and the level of access they had to technology while under their sex trafficker's control. We find support for all of our hypotheses. The results have serious implications for criminal justice policy and practice. 相似文献

In 2017, Russian President Vladimir Putin declared that whichever country becomes the leader in artificial intelligence (AI) “will become the ruler of the world.” Yet Russia lags competitors like China and the United States substantially in AI capabilities. What is Russia's strategy for boosting development of AI technologies, and what role do groups within the Russian elite play in shaping this strategy? Russia's AI development strategy is unique in that it is led not by the government, nor by the private sector, but by state-owned firms. The government's distrust of Russia's largest tech firm, Yandex, has sidelined the company from national AI planning. Meanwhile, Russia's defense conglomerate Rostec publicly appears to focus less on artificial intelligence than on other high-tech priorities. As a result, Russia's AI development has been left to a state-owned bank, Sberbank, which has taken the lead in devising plans for government-backed investment in AI. 相似文献

Despite numerous instrumental achievements, canines are still considered the most effective field method for explosive detection. However, due to strict explosive regulations and safety requirements, it can be a challenge for agencies with "bomb dogs" to train using neat explosive materials. This establishes a need for non-explosive canine training aids with the same volatile component profiles as the explosives that they represent. In order to compare mimic materials to their explosive counterparts, a technique must be established that not only allows for identification of volatile compounds but also can monitor changes in the headspace profile over time with respect to time and temperature. The Automated Training Aid Simulation using SPME (or ATASS) was developed for that purpose. As described, ATASS was used to observe changes in the volatile profile of three explosives (Composition C-4, 2,4-dinitrotoluene (DNT), and triacetone triperoxide (TATP)) and respective prototype training materials (0.1% by mass C-4, 1% by mass 2,4-DNT, and 1% by mass TATP). Samples were prepared in vials and metal tins within a gallon (≈ 3785 mL) paint can to simulate common field techniques for canine training. Monitoring these materials in real time provides a better understanding of the major volatile components present and how the relative abundances of these components can change over time. The results presented indicate that ATASS successfully allows for a sufficient comparison between explosive and non-explosive training materials. 相似文献

Analysis of neonaticide cases from a law enforcement perspective is virtually non-existent in the research literature. Nonetheless,
law enforcement and prosecutors face unique challenges when investigating and prosecuting neonaticide; and a specialized,
informed approach is necessary. By highlighting the crime scene characteristics and autopsy findings of 55 neonaticide victims,
the authors hope to assist the law enforcement and legal communities in their neonaticide investigations. Specifically, this
article clarifies how neonaticide occurs by chronologically examining the pregnancy, the birth and death of the infant, the
subsequent crime scene (or scenes) and the pathological findings. The article also highlights the potential challenges that
may arise during investigation and prosecution of these cases in addition to providing the forensic community with recommended
investigative techniques. 相似文献

A considerable number of individuals show resistance to reform, whereas others, although similarly affected, do not react
in a resistant way at all. Based on research showing that people differ concerning how sensitive they are toward being a victim
of injustice (victim justice sensitivity), we argued that people high in victim justice sensitivity perceive a reform more
as an illegitimate limitation to their freedom resulting in more reactance. Consequently, people high in victim justice sensitivity
should show more resistance to reform. We conducted three studies to test these assumptions. Our studies revealed that physicians
(healthcare reform, Study 1) and students (introduction of tuition fees, Studies 2 and 3) with higher victim justice sensitivity
experienced more reactance and thus showed more resistance to reform. The implications of these results for the implementation
of political reforms are discussed. 相似文献

Should counselors with interpersonal trauma histories work with similarly traumatized clients? How does the work affect them? Current research is inconsistent. This study examines 101 sexual assault and domestic violence counselors' recalled motivations for trauma work, their reported subjective personal changes, and their secondary and vicarious trauma symptoms and burnout. Counselors motivated by interpersonal trauma report both more symptoms and positive changes (including dealing with their own trauma). Those seeking personal meaning report becoming more hypervigilant and self-isolating. Those saying they learned from clients rate symptoms lower, suggesting stress inoculation. Supervisors of trauma counselors should facilitate learning from clients separately from processing the counselor's trauma. 相似文献

Household formation patterns have been adduced in recent years by historians and other social scientists to account for the economic development of western Europe. The so-called European Marriage Pattern, which prevailed throughout northwest Europe, is viewed as having been particularly conducive to early industrialisation and economic growth. But to what extent were household formation systems exogenous to the broader economic and social context in which they were located? Evidence from nineteenth-century Russia indicates that family systems were influenced by the same variables that determined the shape of the local economy; they were part of a complex web of institutions and thus cannot be viewed as independent determinants of economic development. 相似文献

We appreciate Boone’s (2011, this issue) critique of Rogers, Bender, and Johnson’s (2011, this issue) analysis of the Malingered Neurocognitive Dysfunction (MND) criteria. She raised good points and appeared in general agreement regarding several crucial limitations of the MND model. However, Boone remained mostly silent on several issues including the compelling results from our methodological review of MND studies and Criteria A through D. When provided, her comments tended to be very selective and were often presented with little or no empirical support. This contrasting pattern of strong statements and weak evidence appears to unintentionally parallel the MND model, which was documented in our original analysis. As a result of her criticism, however, we clarified our point regarding methodological limitations in establishing levels of TBI and its potential relevance to determinations of feigned cognitive impairment. We hope that these spirited discussions will stimulate a much-needed review and a fundamental revamping, if not replacement, of the MND model. 相似文献

This study examines the effects of taphonomic processes on blunt force trauma (BFT) through an experimental study involving pig heads. Of particular concern is the possibility that taphonomic changes can create pseudo-trauma and/or conceal evidence of actual trauma. BFT was inflicted on 10 pig skulls using a hammer. The skulls were subsequently exposed to the environment for 12 months. Seven taphonomic changes were evaluated: the freeze-thaw cycle; rodent gnawing; carnivore scavenging; presence/weight of soil; presence/weight of rain and snow; movement/displacement of bones; and discoloration due to sun bleaching and grass staining. Taphonomic effects varied between cancellous, compact, fresh, and degreased bone. Freezing and thawing, exposure to rain and snow, movement of the skulls, and soil erosion altered and, in some cases disguised, pre-existing trauma. Rodent and carnivore activity did not obliterate evidence of BFT. Recommendations for evaluating BFT on remains affected by taphonomic processes are presented. As each taphonomic process outlined by this study has the potential to disguise antemortem injury, the authors propose that one must carefully examine large, circular openings in the skull that may represent the remnant evidence of BFT. 相似文献
