Abstract Facial composite images are often used in the criminal investigation process to facilitate the search for and identification of someone who has committed a crime. Since the use of facial composite images is sometimes relied upon as an integral part of an investigation, it is important to ascertain information about the various decisions made and procedures implemented by law enforcement regarding the use of composites. A 39-item survey was developed to examine the prevalence of a number of procedures related to composite production, including the systems implemented, criteria for selecting systems, law enforcement training, satisfaction with systems, legal challenges, and procedural issues with respect to interviewing multiple witnesses and the distribution of composite images. Surveys were distributed to 1637 city, state and county law enforcement agencies nationwide; 163 completed surveys were returned. This paper summarizes our survey results and discusses the implications for investigative procedures, law enforcement training, and future research needs. 相似文献

Abstract Despite problems of validity, self-report measurements are used in clinical practice and research. The aim here was to compare self-ratings by adolescent males who had sexually offended with assessments of the same adolescents made by professionals. Results of two self-report questionnaires were compared with staff estimates. It was assumed that observability of behaviour, social desirability of the adolescents' responses, intellectual difficulties and the presence of neuropsychiatric problems would affect the level of agreement between participant and professional responses. Agreement between staff estimates and self-ratings was generally low. However, some results supported the assumptions: i.e. higher levels of agreement on observable behaviour, higher levels of agreement for adolescents scoring low on social desirability and, most obviously, lower levels of agreement for boys with neuropsychiatric diagnoses. Discrepancies between what adolescents say about themselves through self-ratings and how professionals perceive them cause problems in assessments that rely on self-rating measurements. 相似文献

Abstract This article describes a follow-up study of 14 adolescent sexual offenders who had attended a community treatment programme. A core component of their treatment included outdoor wilderness group therapy. Interviews were conducted with adolescents and parents and tapped several areas including social skills and peer relationships, victim empathy, cognitive distortions, safety plans and coping with high risk situations, sexual offending cycle, perceived level of risk, intimacy and sexuality. The study also examined the child protection service records of the It adolescents. Data from child protection service computer records showed that none of the adolescents had reoffended. Interviews with adolescents and families focusing particularly on the wilderness component of the programme showed positive changes. 相似文献

The infusion of election observation in the political landscape of the Caribbean has presented a range of trends and reactions. Some countries, such as Guyana, have had a more entrenched and controversial history with observation than others. Guyana was the first Caribbean country to have had international observers. This paper presents a survey of the case of Guyana between 1964 and 2001. The article outlines all the observed elections in Guyana during this period with reference to issues of logistics, size, duration and the actors involved. It also assesses the outcomes of international observer presence in these elections and explores the implications for Guyana’s efforts to display acquiescence to the norm of holding free and fair elections. 相似文献

Much of the extant literature regarding women in policing focuses on job stress, perceptions of job performance, and inherent
difficulties associated with their immersion in a traditionally male-dominated profession. Little attention, however, has
been given to perceptions regarding gender and backup preferences among police officers. This study sought to examine the
impact of professional and demographic characteristics of municipal police officers in a southern state on preferences for
male police officers as backup. Multivariate analysis indicated that gender, partner status, race, and marital status significantly
impacted officer preferences for male backup. However, further examination of the interaction effect between gender and partner
status revealed a gap in the preferences for officers with no partners. Although officers with no partners reported lower
overall preferences for male backup than officers with female or male partners, the disparity of preference between male and
female officers with no partners was sizeable. 相似文献

Understanding adolescents’ use of ethnic labels is a key developmental issue, particularly given the practical significance
of identity and self-definition in adolescents’ lives. Ethnic labeling was examined among adolescents in the traditional immigrant
receiving area of Los Angeles (Asian n = 258, Latino n = 279) and the non-traditional immigrant receiving area of North Carolina (Asian n = 165, Latino n = 239). Logistic regressions showed that adolescents from different geographic settings use different ethnic labels, with
youth from NC preferring heritage and panethnic labels and youth from LA preferring hyphenated American labels. Second generation
youth were more likely than first generation youth to use hyphenated American labels, and less likely to use heritage or panethnic
labels. Greater ethnic centrality increased the odds of heritage label use, and greater English proficiency increased the
odds of heritage-American label use. These associations significantly mediated the initial effects of setting. Further results
examine ethnic differences as well as links between labels and self-esteem. The discussion highlights implications of ethnic
labeling and context. 相似文献

While many adolescents and young adults experiment with substances (e.g., alcohol, cigarette smoking, marijuana), recent research
suggests that rural youth and young adults may be more at risk for substance use than their urban counterparts. This study
was designed to examine the longitudinal relationships between rural adolescents’ prosocial behaviors and substance use in
young adulthood. Furthermore, we examined the potential mediating effects of adolescent substance use, academic investment,
and delinquency. Rural youth (N = 531; 263 girls) were surveyed in grades 10–12 (Time 1; M age = 16.17; SD = .91) and again in early adulthood (Time 2). Measures of prosocial behaviors, substance use, academic investment,
and deviant activities were assessed at Time 1. At Time 2, measures of marijuana use, cigarette smoking, and getting drunk
were administered. Overall, the findings showed that rural adolescents who frequently exhibit prosocial behaviors are less
likely to engage in substance use in young adulthood than those who exhibit relatively low levels of prosocial behaviors.
These findings indicate that prosocial behaviors may have positive health consequences, establishing behavioral trajectories
that lead to lower levels of risky health behaviors in adulthood in rural populations. 相似文献
