The difficulty of coordinating service provision in interagency programs is a challenge for many working in public policy. We reflect on lessons learned through evaluating two inter‐agency supported housing programs for people with mental illness and propose a framework outlining components needed for well co‐ordinated service provision. We specify collaborative mechanisms at the policy, agency, service and client level. The key component is the role of an ‘integration coordinator': a person who is able to facilitate relationships and ensure effective information flows. Relationships need to be actively maintained to meet the inevitable challenges that will arise in complex interagency systems. The framework is relevant to policymakers across the public sector, including mental health, drug and alcohol, aged care, and policing.  相似文献

Most researchers rely exclusively on the reports of protective service workers to determine children's abuse history. In this report, information about children's maltreatment experiences is obtained from protective service workers and three supplementary sources of data: parents, medical records, and clinical observations. Fifty-six children from 34 families receiving protective services for verified reports of physical abuse, neglect, sexual abuse, and/or emotional maltreatment participated in the study, with most children known to have experienced more than one type of abuse. The supplementary data provided important information about the range and severity of children's maltreatment experiences. Review of the parent and medical record data led to identification of 28 children who had additional types of maltreatment experiences that were not reported by their protective services workers—nine cases of physical abuse, two cases of neglect, five cases of sexual abuse, and 12 cases of emotional maltreatment. Supplementary data also revealed information about incidents of specific types of abuse that were more severe than those reported by the children's protective service workers in an additional 24 cases. A method was devised to synthesize information provided from the different sources of data examined in this report to derive 0–4 point ratings of four categories of maltreatment experiences: (1) physical abuse, (3) neglect, (3) sexual abuse, and (4) emotional maltreatment. The Kappa reliability coefficients for each of these scales were .88, .73, .83, and .90, respectively. Data demonstrating the relationship between these maltreatment ratings and various indices of the children's socioemotional and cognitive functioning were also presented to provide preliminary support for the validity of these scales. The findings from this study suggest that multiple sources of data should be examined in order to obtain accurate assessments of children's maltreatment experiences, and that independent raters can synthesize discrepant data to obtain reliable and valid estimates of children's abuse history. Clinical and methodological issues relevant to the improved assessment of children's maltreatment experiences are also discussed.  相似文献

A new, fast, and ultra-sensitive headspace sampling method using the Capillary Microextraction of Volatiles (CMV) device is demonstrated for the analysis of ignitable liquid residues (ILRs) in fire debris. This headspace sampling method involves the use of a heated can (60°C) to aid in the recovery of volatile organic compounds (VOCs) from medium and heavy petroleum distillates. Our group has previously reported the utility of CMV to extract gasoline at ambient temperature in less than 5 min in the field. This work evaluates the recovery and analysis of low mass loadings (tens of ng) of VOCs from charcoal lighter fluid, kerosene, and diesel fuel. Nonane, decane, undecane, tridecane, tetradecane, and pentadecane were selected for evaluation of recovery to represent these ILR classes. The face-down heated can headspace sampling technique was compared to the previously reported, non-heated, paper cup headspace sampling technique. Mass recovery improvements of 50%–200% for five of the six target compounds in diesel fuel were achieved compared to the non-heated sampling method. The average relative standard deviation (reported as % RSD) between the replicate trials decreased from an average of 28% to 6% when using the heated can method. Ignitable liquids were spiked onto burned debris in a live burn exercise and sampled using the heated can and paper cup headspace sampling techniques. The heated sampling technique reported here, for the first time, demonstrates an effective extraction method that when coupled to a portable GC–MS instrument allows for a sampling and analysis protocol in the field in less than 30 min.  相似文献

ABSTRACT

Drugging victimization is an understudied phenomenon. This study examines the relationship between the campus party culture and drugging victimization. Campus party culture has been shown to influence risk of other types of victimization, and there is reason to believe it may also influence drugging victimization. Using three behavioral indicators of participation in the campus party culture—binge drinking, Greek life membership, and first-year student status—this study estimates the main effect of each indicator, and their interaction, on undergraduates’ rates of drugging victimization. Estimating a generalized linear model using a large random sample (N = 6,931) from three universities, results show that each party culture variable and their three-way interaction significantly influenced students’ rate of drugging victimization. Sorority members who were first-year students and binge drank at least once in the past month had significantly higher rates of drugging victimization compared to all other groups of students.  相似文献

ABSTRACT

Many universities and colleges now require all “responsible employees,” including faculty, to report known or suspected sexual misconduct to designated Title IX administrators. The intention of these mandatory reporting policies is to ensure institutional accountability and compliance with Title IX’s prohibition against sexual and gender-based discrimination. Yet, critics argue that such policies are overreaching, paternalistic and, ironically, discriminatory. Drawing from prior research on sexual victimization and original exploratory data on gender-based college harassment, this article provides a critical perspective that delineates both the intended goals and unintended consequences of Title IX’s mandatory reporting policies, specifically focusing on three overlapping issues: ambiguous definitions, reporting risks, and faculty’s role in disclosure. We conclude by proposing alternative strategies for achieving Title IX’s objectives.  相似文献

This issue of Criminal Law and Philosophy contains three papers on a topic of increasing importance within the field of “neurolaw”—namely, the implications for criminal law of direct brain intervention based mind altering techniques (DBI’s). To locate these papers’ topic within a broader context, I begin with an overview of some prominent topics in the field of neurolaw, where possible providing some references to relevant literature. The specific questions asked by the three authors, as well as their answers and central claims, are then sketched out, and I end with a brief comment to explain why this particular topic can be expected to gain more prominence in coming years.  相似文献
