Designing tools for ‘joined up’ homelessness prevention: Insights from one case study

Homelessness is a complex social problem with significant health and economic consequences. Prevention-based responses seek to reduce the number of people who go on to experience homelessness, but effective homelessness prevention is challenging to implement and can require service integration across mainstream referral organisations and specialist homelessness service agencies. The ‘At-Risk Screening Tool’ was piloted over August 2018 to March 2019 to enable such mainstream and specialist organisations to coordinate their screening and referral process in the context of homelessness prevention. The tool was used by mainstream referral agencies to assess a client's risk of homelessness, and a tailored referral pathway to a specialist homelessness agency was produced based on this assessment. This article discusses the evaluation of the pilot, exploring three key insights around service integration in a community service context. These insights emphasise the importance of embedding an awareness of staff needs and organisational constraints into the design and application of similar tools.     

牛四核苷酸STR基因座的筛选和多态性分析

目的筛选阴影带出现率低且多态性较高的牛四核苷酸STR基因座。方法用Tandem repeats finder软件搜索牛基因组中的四核苷酸重复STR序列片段,用Primer Premier 5.0软件设计引物,然后扩增、电泳,筛选出符合要求的STR基因座,并对100份无关黄牛个体血样进行STR基因座分型。结果共筛选出6个具有多态性的牛四核苷酸重复STR基因座（B006、B007、B008、B022、B025、B026）,其100份无关黄牛个体血样的累积个体识别率和累积非父排除概率分别为0.99995和0.859591。结论本研究筛选出的6个四核苷酸STR基因座阴影带出现率低且多态性较高,可用于牛的个体识别和亲子鉴定的研究。     

鉴定科学LC-MS／MS多反应监测筛选分析血液中132种毒药物

目的建立血液中常见毒药物的LC-MS/MS筛选分析方法。方法采用多反应监测(MRM)模式,以目标物的保留时间和母离子／子离子对为指标进行筛选分析。建立LC-MS/MS 库和定性认定准则,并考察了方法的有效性。结果多反应监测筛选体系兼具有选择离子扫描的曼敏度和二级质谱的特征性,血液中132种毒药物筛选分析的最低检出限为0．1- 10ng/mL．其中83％的检出限≤lng/mL。鉴定应用表明方法的检出率和可靠性良好。结论该筛选分析方法能满足法医毒物学和临床毒物学检测中毒或治疗浓度目标物的需要,且能扩展至其它生物检材。     

论教育的筛选功能与应试教育

党校教育的层层筛选形成人的受教育水平（或学历）的差异，同时也由此导致人的社会地位和社会职业的不同，这是造成教育的竞争与应试教育的根本原因。应试教育是对我国当前教育弊端的概括，其实质是指教育筛选功能的过度张扬对教育促进人的全面发展功能的侵害。基于筛选的应试教育与基于发展的素质教育是教育的两个不可分割的组成部分，经处于一定的张力之中，理想的教育是实现二的均衡。

Deceptive behaviour and instrumental violence among psychopathic and non-psychopathic violent forensic psychiatric patients

Deceptive behaviour and instrumental violence are well-known psychopathic features and as such play important roles in the assessment of psychopathy. This study examined first, the nature of the violence committed by offenders that have been admitted to forensic psychiatric care and whether scores on the Psychopathy Checklist: Screening Version (PCL:SV), Part 1, were associated with the instrumentality of violence. Second, we examined the proneness of offenders to re-frame the instrumentality in their past violent crimes, and whether this was associated with scores on the PCL:SV. The results show that the PCL:SV, Part 1 (interpersonal/affective features), was positively related to the officially coded instrumentality of the violent crimes. As expected, this association disappeared when the instrumentality was self-reported. However, the majority of the patients tended to exaggerate the reactivity of their violent crimes when it was self-reported, indicating that most offenders, independently of level of psychopathy, used deception when questioned about the characteristics of their past violent crimes. The reasons for, and implications of, the use of deception are discussed.     

Terrorism and Profiling

A key problem for counterterrorism is how large numbers of individuals can be screened most efficiently to discover terrorists. This question arises at security checkpoints of all kinds, from roadblocks to airline security counters. Some argue that certain categories of individuals, for instance, young Muslim men in the airline context, should be screened more heavily than others. Others deride this as racial profiling, and argue that any such scheme would be easily evaded. I examine a model of searching for terrorists among a population divided into categories that vary in their potential reliability or ease of recruitment as agents of terrorist attacks. The equilibria in the model feature profiling, in that different categories are searched with different intensities. Practical difficulties in implementing a rational profiling scheme are discussed.     

Screening procedures in the United Kingdom for positions of trust with children

Abstract

Child services organisations need policies that minimise the risk of sexual abuse of the children in their care. In particular, managers (and the public) are justifiably concerned when abuse is perpetrated by individuals who should not have been working with children in the first place. Unfortunately, there has been relatively little work on determining unacceptable risk for sexually abusive behaviour in child service organisations. The purpose of this paper is to describe the contexts in which screening procedures are appropriate, review the academic literature on screening procedures and present the results of a pilot survey of current screening practices in the United Kingdom. We comment on the effectiveness of screening measures available for use by organisations and provide suggestions for improvement. Specifically, we recommend that screening procedures consider risk factors associated with the onset and persistence of child sexual abuse perpetration.     

Dilemmas and consequences of prior criminal record: a criminological perspective from England and Wales

This article considers the contemporary architecture of criminal record usage in England and Wales. We focus upon impact on ‘employment status’, partly because work is often now seen as key to good health and other self-esteem indicators in the modern world. First, we examine in the context of England and Wales, (a) the development of the contemporary criminal record system and extent of availability of prior record information in terms of employment (and other licensing purposes) and (b) the factors that helped shape the current architecture. Second, this article outlines what is known from the British criminological literature on employment and conviction records and what more is needed in terms of criminological research. Finally, we consider how convictions become ‘spent’ – in particular the English approach to ‘expungement’/sealing of the criminal record according to the 1974 Rehabilitation of Offenders legislation.     

Brief mental health screening of prison entrants: psychiatric history versus symptom screening for the prediction of in-prison outcomes

While prisoners are known to suffer very high rates of mental illness, evidence is often lacking to inform the development of effective approaches to prison mental health service provision, including the approach to mental health screening. In addition, research to date has been dominated by prevalence studies and little is known about the mental health needs of prisoners over time. A random sample of prison entrants was recruited from a large remand and reception prison in New South Wales, Australia (n = 707) for the completion of a brief health survey. A second survey was completed during the subsequent six months (n = 317) in order to examine the effect of timing of assessment on mental health status. Those followed up within three months (n = 182) were further included in an analysis of predictive validity comparing the performance at baseline of self-reported history of previous diagnosis versus current symptom screening for psychological distress, in predicting subsequent mental illness. When assessed over six months from prison entry, mental health status was found to vary by timing of assessment. At prison entry, self-reported history of previous diagnosis of a mental health disorder was found to be a better predictor of mental illness over three months than screening for psychological distress.
