The effects of target discriminability and criterion placement on accuracy rates in sequential and simultaneous target-present lineups

Abstract

Participants attempted to select previously studied faces from lineups that were administered either sequentially (test faces presented one at a time) or simultaneously (test faces presented altogether). Target discriminability was manipulated by varying the number of facial features that could be used to distinguish the study face from the other test faces (foils) or by varying study face exposure duration. In addition, decision criterion level was manipulated via an instruction manipulation. Results indicated that sequential participants adopted a stricter decision standard under high criterion instructions compared to simultaneous participants. Under liberal criterion setting instructions, the rate at which the target was selected was comparable across lineup procedures. Target discriminability affected target selections to a greater extent in simultaneous compared to sequential lineups. We discuss the applied implications that these findings have regarding correct identifications from lineups.     

Understanding how sexual offenders compare across psychiatric and correctional settings: examination of Canadian mentally ill sexual offenders

Abstract

Much of what is known about sexual offenders is based on correctional samples and then applied across settings based on the assumption that this group is homogeneous. In this study, 149 files were compared, including 108 cases from the forensic mental health system (FMH) and 41 cases from the correctional system (COR). Although many similarities were observed between the FMH and COR groups, the results also revealed important differences. The FMH group was characterised by more frequent hospitalisations, higher rates of major mental illness and single status. The COR group was characterised by a history of physical and sexual abuse, family history of addictions, more intrusive sexual offences and higher rates of offending. These results highlight different profiles for sexual offenders in forensic mental health and correctional settings and challenge us to consider the implications for assessment, treatment and risk management of this unique group of sexual offenders.     

What do students really know about criminal justice?

This survey of three hundred and twenty undergraduate students attempted to determine their knowledge of crime and punishment in North Carolina. Respondents answered a series of open- and closed-ended questions regarding various legal topics, such as statutory rape and the legal ages for tobacco and alcohol use. The participants were also asked to list punishments for various offenses, such as possession of marijuana, driving while intoxicated, and rape. They were then asked to define certain legal terms such as larceny. The results indicated that most students were unable to provide correct corresponding punishments for many offenses. They were also unable to accurately define various legal terms, such as robbery or rape. The implications for stronger education in the area of criminal justice are discussed.     

Foreign and Defence Policy on Australia's Political Agenda, 1962–2012

This paper explores the content of the Australian foreign and defence policy agenda over the past 50 years, finding evidence of both continuity and change. Australian political leaders have generally committed to cooperation with international institutions, wealth creation through engagement with Asian economies in particular, and security through the American alliance. In this period, changes in foreign policy approach either concerned marginal issues or were driven significantly by exogenous factors: by changes in the international environment or by global events that propelled a reconsideration of Australian foreign and defence policy interests. However, periods of policy change and significant public attention in – particular around the Vietnam and Iraq wars – illustrate the continued relevance of political choices and agency. Both conflicts and debates around them ushered in changing foreign and defence policy considerations, and both raised fundamental questions about Australian security and independence in the context of the American alliance.     

Reactions to Dating Violence Research: Do Difficulties with Distress Tolerance Increase Negative Reactions?

Recent research has begun to examine whether participants in dating violence studies perceive any benefit from the research and/or experience emotional distress as a result of having participated. Such information is important for Institutional Review Boards (IRBs) and researchers in determining ethical and appropriate protections for participants. In the current study, we examined participants’ reactions to answering questions on dating violence victimization and perpetration utilizing a sample of female college students (N?=?282). We also examined whether distress tolerance was associated with research reactions and moderated the relation between reports of victimization/perpetration and negative emotional reactions to the research. Findings demonstrated that negative emotional reactions to the research did not differ between individuals with or without previous dating violence. Further, distress tolerance had a main effect, but not a moderating effect, on negative emotional reactions to research participation. Implications of these findings for future research and IRBs are discussed.     

Screening for Substance Use Disorders as a Supplement to Caseworker Assessment Among Foster Care–Involved Families

Parental substance abuse is a major factor in families experiencing foster care placement, yet little is known about the potential of screening in determining risk or identifying subpopulations for which elevated risk occurs. One Midwestern state recently implemented screening. This research uses information gathered as part of the screen's implementation to conduct a latent class analysis. The research was extended to provide a detailed examination of differences in child and family characteristics across classes, and to compare the screen results with caseworker impressions. Three distinct typologies emerged, with the high-risk and moderate-risk designations comprising only one quarter of the cases.     

The Geography of Governance in Africa: New Tools from Satellites,Surveys and Mapping Initiatives

Abstract

Research on decentralization in Africa and beyond has made clear that the quality of decentralized governance is highly variable across localities within countries. In light of that variation, this article has three goals: first, we critique existing academic research on the quality of governance in light of work on decentralized governance in Africa; second, we provide a conceptual map of how to theorize subnational variation in the quality of governance in settings characterized by considerable dependence on higher authorities for revenues; and third, we outline a series of data initiatives that offer the opportunity to study local and regional politics in new and exciting ways across the region. We conclude with great optimism about the prospects for innovative work on decentralized governance within countries across the region.     

Legal Consciousness and Responses to Sexual Harassment

Studies of legal mobilization often focus on people who have perceived some wrong, but these studies rarely consider the process that selects them into the pool of potential "mobilizers." Similarly, studies of victimization or targeting rarely go on to consider what people do about the wrong, or why some targets come forward and others remain silent. We here integrate sociolegal, feminist, and criminological theories in a conceptual model that treats experiencing sexual harassment and mobilizing in response as interrelated processes. We then link these two processes by modeling them as jointly determined outcomes and examine their connections using interviews with a subset of our survey respondents. Our results suggest that targets of harassment are selected, in part, because they are least likely to tell others about the experience. We also discuss strategies that workers employ to cope with and confront harassment. We find that traditional formal/informal dichotomies of mobilization responses may not fully account for the range of ways that individuals respond to harassment, and we propose a preliminary typology of responses.     

Psychiatric diagnosis as a risk marker for victimization in a national sample of children

Research examining childhood abuse has shown an association between victimization and psychiatric diagnoses (e.g., posttraumatic stress disorder, depression). Historically, psychiatric diagnoses have been emphasized as a consequence of victimization, with less research examining if it also functions as a risk factor for further victimization, perhaps making diagnoses a general victimization risk marker. In addition, much of this research has emphasized particular types of victimization such as childhood physical or sexual abuse. Researchers have given less attention to other forms of victimization (e.g., peer victimization, witnessed violence) or a diverse victimization history. Using the Juvenile Victimization Questionnaire (JVQ) we surveyed parents and children between the ages of 2 and 17 using a random digit dial (RDD) methodology. We examined the relationship between a number of different forms of victimization (termed poly-victimization ) in the preceding year and parent-reported lifetime psychiatric diagnosis. Results show that children with a psychiatric diagnosis have significantly higher rates of victimization than children without a psychiatric diagnosis. In addition, using logistic regression models, we find that psychiatric diagnosis was associated with increased risk for poly-victimization, conventional crime victimization, maltreatment, peer or sibling victimization, and witnessing violence, but not sexual abuse. The results highlight the need to consider psychiatric diagnoses as a risk marker for past and possible future victimization. In addition, the importance of obtaining a comprehensive and more diverse victimization history when working with children is highlighted.
