The influence of sample type,presentation format and strength of evidence on juror simulation research

Abstract

Recent research has indicated that treatment of psychopaths in therapeutic communities is problematic in terms of high rates of attrition, low levels of motivation and increased reconviction. However, there has been little previous research investigating in detail how the behavioural diffculties posed by psychopaths in therapeutic community settings could be systematically monitored is order to assess change. This paper reports on the development of a checkilst completed by prison officers designed to measure behaviours association with a poor adjustment to a prison based therapeutic community. Behaviour checklist accores showed statistically significant correlations with the Hare Psychopathy Checklist Revised (PCL-R, Hare 1991), patticularly with Factor 1 scores measuring intarpersonal aspects of psychopathy. The potential for developing this method as a type of dynamic assessment for psychopaths undertaking treatmant is discussed.     

Developing the North,Defending the Nation? The Northern Australia Development Committee, 1945–1949*

The Northern Australia Development Committee (NADC) was established in late 1945 to coordinate the efforts of the Commonwealth, Queensland and Western Australian governments in developing the north of the continent. At the outset, defence considerations were uppermost. However, the NADC soon became entangled in disputes among Commonwealth departments and personalities over the relevance of northern development to national defence. Some — notably the Department of Defence — insisted that northern Australia no longer possessed special strategic significance. Others — notably the Department of External Affairs — argued that northern development must be conceived within a broader geo‐political context. This paper examines the NADC's entanglement in these disputes, and explains how this entanglement contributed crucially to the committee's ineffectualness and early demise.     

Visualisation of fingermarks and grab impressions on dark fabrics using silver vacuum metal deposition

Vacuum metal deposition (VMD) involves the thermal evaporation of metal (silver) in a vacuum, resulting in a uniform layer being deposited on the specimen being treated. This paper examines the use of silver on dark fabrics, thus offering a simpler operation and more obvious colouration to that of the traditional use of gold and zinc metals which must be evaporated separately. The aim of this study was to investigate the effect of fabric type, donor, mark age and method of fingermark deposition on the quality of marks visualised using silver VMD. This was achieved by collecting fingermark deposits from fifteen donors, of both sexes and various ages, by a grab or a press method. Four different fabrics: satin, polyester, polycotton and cotton were studied over a 10 day timeline of 1, 2, 3, 4, 5, 6, 7, 14, 21 and 28 + days. It was found that satin and polyester gave the most positive results, with polyester often producing excellent ridge detail. Cotton and polycotton were less successful with no ridge detail being observed. The donors also had an observable effect on the results obtained probably due to variations in secretions produced or pressures applied during specimen collection. The age of the mark or the method of mark deposition had little influence on the results obtained. Silver VMD is a viable process for visualising marks on certain dark fabrics and has the advantage over gold/zinc VMD in that the marks visualised are light in colour which contrasts well against the dark background.     

The Contrived Defense and Deterrent Threat Doctrines: A Reply to Professors Finkelstein & Katz

What is the relationship between the permissibility/impermissibility of the part and the permissibility/impermissibility of the whole? Does the moral or legal status of a constituent part of an actor’s course of conduct govern the status of the actor’s whole course of conduct or, conversely, does the moral and legal status of the actor’s whole course of conduct govern the status of the constituent parts? This broader issue is examined in the more specific contexts of the contrived defense and deterrent threat doctrines. The latter doctrine concerns whether a prima facie impermissible act of carrying out a threatened action may be rendered permissible if embedded within an overall permissible course of action including the issuance of a deterrent threat that fails to induce compliance. The contrived defense doctrine addresses the permissibility of an actor who contrives or culpably causes the conditions of her own defense. This essay considers the claim—advanced by Claire Finkelstein and Leo Katz—that the contrived defense and deterrent threat doctrines are sufficiently related such that the preferable approach to each doctrine informs and supports the preferable approach to the other. In each, the permissible/impermissible status of the whole governs the status of the part. Regarding contrived defenses, the impermissibility of the actor’s whole course of conduct renders the otherwise permissible constituent part relating to the defense also impermissible. And regarding deterrent threats, the permissibility of the actor’s whole course of conduct renders the otherwise impermissible constituent parts also permissible. This essay challenges the claimed linkage between the contrived defense and deterrent threat doctrines by proposing hypothetical situations in which the claimed parallel doctrines collapse into each other. As a result, the application of the preferred approaches to each doctrine generates a contradiction.     

The promise of primary prevention home visiting programs: a review of potential outcomes

Home visitation (HV) is a promising service delivery model, despite a history of mixed documented results. Compiling results on the promising family and child development outcomes in the HV literature has utility for current programs and those under development. We review traditional outcomes (e.g., child maltreatment prevention) from the literature on HV, but we also present nontraditional outcomes (e.g., community connection) that may be relevant for future evaluations. Programs that document their implementation and study their outcomes through a thoughtful, planned process may capture important and much needed information on strengthening families through HV.
