There is growing interest in the health correlates of people detained in police custody, and a number of innovations have been introduced to try to meet the complex needs of detainees. The implementation of Criminal Justice Liaison and Diversion (CJL&D) Services commissioned by the Department of Health in England is a substantial part of this investment. In this paper, we describe data from 858 detainees who were referred to the CJL&D service of a busy metropolitan police station in the North East of England. The detainees referred to the service had complex mental health needs, substance misuse and a range of vulnerabilities requiring specific intervention. The effective operation of these teams and how they interface with health and criminal justice systems also depend upon a number of systematic issues that emanate both from within the teams, and from external policy drivers. 相似文献

In forensic intelligence-gathering it would be useful to be able to estimate the size of a perpetrator's foot from a standing bare footprint found at the scene of crime. Currently, the advice is to add a fixed amount to the length of the footprint (typically 1.5 or 2.0 cm), but there is little evidence for this approach. This study used measured footprint and actual foot lengths from 146 participants from the white British student population of a University in the UK. Data were analysed using multiple regression with foot length as the dependent (outcome) variable and footprint length and sex as the independent variable/factor respectively. Sex was not a significant predictor. The regression equation for the best estimate of the foot length is 19.89 + 0.95 × print length ± 8 mm. 相似文献

Sexual assault samples are among the most frequently analyzed in a forensic laboratory. These account for almost half of all samples processed routinely, and a large portion of these cases remain unsolved. These samples often pose problems to traditional analytic methods of identification because they consist most frequently of cell mixtures from at least two contributors: the victim (usually female) and the perpetrator (usually male). In this study, we propose the use of current preliminary testing for sperm detection in order to determine the chances of success when faced with samples which can be good candidates to undergo analysis with the laser microdissection technology. Also, we used laser microdissection technology to capture fluorescently stained cells of interest differentiated by gender. Collected materials were then used for DNA genotyping with commercially available amplification kits such as Minifiler, Identifiler Plus, NGM, and Y‐Filer. Both the methodology and the quality of the results were evaluated to assess the pros and cons of laser microdissection compared with standard methods. Overall, the combination of fluorescent staining combined with the Minifiler amplification kit provided the best results for autosomal markers, whereas the Y‐Filer kit returned the expected results regardless of the used method. 相似文献

Undocumented Border Crosser (UBC) deaths in Arizona are a major issue faced by medicolegal authorities. Currently, the Maricopa County Office of the Medical Examiner (MCOME) is in possession of over two hundred unidentified individuals, more than half of whom are presumed to be UBCs. The primary goal of this study was to address the growing number of UBC deaths in Maricopa County in order to provide a more comprehensive picture of this important anthropological issue within the state of Arizona. Of the 107 total UBC cases evaluated for the study, the majority were male and age estimates for all individuals were between 15 to 60 years old. Modeled after the recording system established by the Pima County Office of the Medical Examiner, the biographic and geographic data for these cases were entered into a new UBC database at MCOME and later added to the online Map of Migrant Mortality. 相似文献

Parent-child agreement on child maltreatment was examined in a multigenerational study. Questionnaires on perpetrated and experienced child maltreatment were completed by 138 parent-child pairs. Multi-level analyses were conducted to explore whether parents and children agreed about levels of parent-to-child maltreatment (convergence), and to examine whether parents and children reported equal levels of child maltreatment (absolute differences). Direct and moderating effects of age and gender were examined as potential factors explaining differences between parent and child report. The associations between parent- and child-reported maltreatment were significant for all subtypes, but the strength of the associations was low to moderate. Moreover, children reported more parent-to-child neglect than parents did. Older participants reported more experienced maltreatment than younger participants, without evidence for differences in actual exposure. These findings support the value of multi-informant assessment of child maltreatment to improve accuracy, but also reveal the divergent perspectives of parents and children on child maltreatment. 相似文献

Understanding how sexual offenders experience prison and its environment is important because such experiences can impact on rehabilitation outcomes. The purpose of this research investigation was to explore the rehabilitative and therapeutic climate of a recently re-rolled sexual offender prison. The research took a mixed methods approach and consisted of quantitative and qualitative phases. There were differences between prisoners and staff on their perception of the prison climate and for prisoner and staff relationships. The qualitative results helped to explain the quantitative findings and added a more nuanced understanding of the experience of the prison, the nature of prisoner and staff relationships and the opportunities for personal growth within the prison. The study has important implications for prisons that co-locate sexual offenders and want to provide an environment conducive to rehabilitation. 相似文献

Several previous studies have found that interventions by security forces against criminal organisations result in increased violence related to organised crime. However, much less is known about how and why this effect occurs. Our study not only identifies the causal mechanisms that explain this outcome, but also evaluates the empirical validity of these mechanisms. Employing a novel data set, we find that following security-force intervention, the number of criminal organisations increases, and such greater fragmentation in turn raises the incidence of violence among criminal organisations as the relative power of the organisations changes. We employ a mediation model to verify the existence of these causal mechanisms. In addition, we find a decreasing rate of rise in levels of violence as the number of organisations increases. 相似文献

Drug-related homicides in Mexico have increased to levels never before seen and organised crime has evolved accordingly, becoming more fragmented and diverse. This work analyses the evolution of organised crime and drug-related violence in Mexico by examining how drug trafficking organisations (DTOs) communicate through the messages left next to executed bodies from 2007 to 2011. Results suggest that the use of narcomessages has changed and developed in parallel with the evolution of organised crime. In the beginning, DTOs used their victims merely to position themselves. Over time, as the organisations became stronger, they began to direct and sign their narcomessages. By 2009, rivalries were firmly entrenched between several criminal groups, even while the increasing violence led to the creation of new groups with the stated purpose of defending citizens. The evolution of organised crime is observed by the fragmentation of existing groups, the consolidation of new alliances, and the creation of new groups. 相似文献

The changing nature of the transition to adulthood in western societies, such as the United States, may be extending the length
of time parents are engaged in “parenting” activities. However, little is known about different approaches parents take in
their interactions with their emerging-adult children. Hence, this study attempted to identify different clusters of parents
based on the extent to which they exhibited both extremes of control (psychological control, punishment, verbal hostility,
indulgence) and responsiveness (knowledge, warmth, induction, autonomy granting), and to examine how combinations of parenting
were related to emerging adult children’s relational and individual outcomes (e.g. parent–child relationship quality, drinking,
self-worth, depression). The data were collected from 403 emerging adults (M age = 19.89, SD = 1.78, range = 18–26, 62% female) and at least one of their parents (287 fathers and 317 mothers). Eighty-four
percent of participants reported being European American, 6% Asian American, 4% African American, 3% Latino, and 4% reported
being of other ethnicities. Data were analyzed using hierarchical cluster analysis, separately for mothers and fathers, and
identified three similar clusters of parents which we labeled as uninvolved (low on all aspects of parenting), controlling-indulgent (high on both extremes of control and low on all aspects of responsiveness), and authoritative (high on responsiveness and low on control). A fourth cluster was identified for both mothers and fathers and was labeled
as inconsistent for mothers (mothers were above the mean on both extremes of control and on responsiveness) and average for fathers (fathers were at the mean on all eight aspects of parenting). The discussion focuses on how each of these clusters
effectively distinguished between child outcomes. 相似文献
