Predicting Serial Killers' Home Base Using a Decision Support System

The effectiveness of a geographical decision support tool (Dragnet) forlocating the base of serial offenders was compared across 570 modelscomprised of a range of negative exponential functions, buffer zonecomponents, and normalization parameters. The models were applied to thebody disposal locations within each series for 70 U.S. serial killers. Twonormalization parameters were compared for all functions. The test ofeffectiveness was a specifically defined measure of search cost. Whenapplied to the Dragnet predictions it was found that the specially developednormalization parameter (QRange) produced the optimal search costs. Theoptimal search cost was also found to be for a function that did not includeany buffer zone. The optimal, average search cost across the whole samplewas 11% of the defined search area. Fifty-one percent of the offendersresided in the first 5% of the search area, with 87% in the first 25%. Allresided in the total defined search area. These results support thepotential for operational tools using such procedures as well ascontributing to our understanding of criminal's geographicalbehavior. The applicability to other forms of serial crime is considered.     

Party strategies and electoral competition in post-Communist countries: Evidence from Poland

Poland's major post-Communist party, the SLD, was an electorally successful legacy party during the 1990's. An analysis of Polish National Election Studies data and data from a separate study of new firm creation in Poland indicates their success was built on two important and related factors. One is the growth of new firms, which stimulated the growth of a centrist constituency who voted for parties supporting economic reforms. Second, the SLD adapted to this constituency by themselves becoming more economically liberal, as documented by Grzyma?a-Busse (2002). A conditional logit model of voter choice in the 1997 and 2001 elections relates votes to the distance between voters' preferences on economic policies and the positions of the competing parties. From this analysis we estimate that if the SLD had remained an ideological non-reformist party as did the KS?M in the Czech Republic and the CPRF in Russia it would have been a far weaker party as measured by vote and seat shares. Without the new firm creation, an ideological SLD cum KS?M could have been electorally successful as was the CPRF. The paper concludes by contrasting the the Polish, Czech and Russian post-Communist parties and extending the implications of the results to other developing and industrial economies faced with the need for structural change.     

An experimental study of the effect of structured videotape feedback on adolescent group psychotherapy process

Group psychotherapy with disturbed undersocialized adolescents requires modification of traditional group psychotherapy methods. The effectiveness of a structured, brief video-tape feedback and discussion on group psychotherapy process with this population was studied by an analysis of detailed ratings of each statement, or process unit; in randomly selected videotapes from a control and experimental group during a nine-month period. Significant differences in level of intimacy of verbal content and in frequency of feedback about behavior in content indicate that this technique is effective in facilitating group psychotherapy goals.Received Ed.D. from University of Kentucky.

In a World of Their Own: Security‐cleared Counsel,Best Practice,and Procedural Tradition

This article charts how security‐cleared counsel have been constructed as a mechanism for managing the tension between security and fairness in secret trials and transferred across national boundaries as an example of ‘best practice', before going on to evaluate recent cross‐cultural and transnational research on this ‘best practice'. Particular attention is paid to the central role played by the European Court of Human Rights (ECtHR) in promoting the role of ‘special advocates’ and a contrast is made between the methodologies deployed by the Court and those used in recent research to identify and problematize ‘best practice’ within the closed world of security‐cleared counsel. The article then goes on to explore the relationship between ‘best practice’ and procedural tradition and argues that normative solutions advancing ‘best practice’ need to pay careful attention to the procedural contexts and cultures in which they are embedded.     

Laser desorption/ionization time-of-flight mass spectrometry of triacylglycerols and other components in fingermark samples

The chemical composition of fingermarks could potentially be important for determining investigative leads, placing individuals at the time of a crime, and has applications as biomarkers of disease. Fingermark samples containing triacylglycerols (TAGs) and other components were analyzed using laser desorption/ionization (LDI) time-of-flight mass spectrometry (TOF MS). Only LDI appeared to be useful for this application while conventional matrix-assisted LDI-TOF MS was not. Tandem MS was used to identify/confirm selected TAGs. A limited gender comparison, based on a simple t-distribution and peaks intensities, indicated that two TAGs showed gender specificity at the 95% confidence level and two others at 97.5% confidence. Because gender-related TAGs differences were most often close to the standard deviation of the measurements, the majority of the TAGs showed no gender specificity. Thus, LDI-TOF MS is not a reliable indicator of gender based on fingermark analysis. Cosmetic ingredients present in some samples were identified.     

From ‘Doctor Knows Best’ to Dignity: Placing Adults Who Lack Capacity at the Centre of Decisions About Their Medical Treatment

In 1989, the House of Lords first derived a ‘best interests’ test for the medical treatment of adults who lack capacity from the doctrine of necessity and, now codified, the test continues to apply today. The Mental Capacity Act 2005 sets out a non‐exhaustive checklist of relevant considerations, but it gives no particular priority to the patient's wishes. There is also no formal expectation that the patient will participate directly in any court proceedings in which her best interests are to be determined. This article will consider the advantages and disadvantages of providing additional guidance to decision‐makers in order to help them navigate both taking seriously the wishes of people who lack capacity and, at the same time, not abandoning patients who need help and support. More specifically, this article advocates formalising current best practice in the Court of Protection through the introduction of a series of rebuttable presumptions, or starting points.     

The use of the M-Vac® wet-vacuum system as a method for DNA recovery

Collecting sufficient template DNA from a crime scene sample is often challenging, especially with low quantity samples such as touch DNA (tDNA). Traditional DNA collection methods such as double swabbing have limitations, in particular when used on certain substrates which can be found at crime scenes, thus a better collection method is advantageous. Here, the effectiveness of the M-Vac® Wet-Vacuum System is evaluated as a method for DNA recovery on tiles and bricks. It was found that the M-Vac® recovered 75% more DNA than double swabbing on bricks. However, double swabbing collected significantly more DNA than the M-Vac® on tiles. Additionally, it was found that cell-free DNA is lost in the filtration step of M-Vac® collection. In terms of peak height and number of true alleles detected, no significant difference was found between the DNA profiles obtained through M-Vac® collection versus double swabbing of tDNA depositions from 12 volunteers on bricks. The results demonstrate that the M-Vac® has potential for DNA collection from porous surfaces such as bricks, but that alterations to the filter apparatus would be beneficial to increase the amount of genetic material collected for subsequent DNA profiling. These results are anticipated to be a starting point to validate the M-Vac® as a DNA collection device, providing an alternative method when DNA is present on a difficult substrate, or if traditional DNA collection methods have failed.     

Police recruits and perceptions of trust in diverse groups

Trust is critical in ensuring public co-operation with police and in turn building police legitimacy. Trust has been regarded as especially critical when police have sought to develop more positive interactions with diverse groups. Understanding how police officers perceive others and how this shapes trust in members of diverse groups is still developing. This study contributes valuable information regarding police perceptions of trust in minority group members; an area under-researched in policing studies, particularly in an Australian context. To understand how police recruit perceptions of socialization, interaction, and living and work choices affects their perceptions of trust in diverse groups of people, data were collected from a population of Police Recruits and Protective Service Officers (N = 1609) during pre-service awareness training. These were used in a Stepwise OLS model to ascertain opinions of trust in people distinguished by diverse identities. The results show socializing, and experiencing positive interaction whilst socializing with people from diverse groups, and the age of the participants, has a significant impact on the perceptions of trust police recruits have in members of diverse groups. However, this may not be enough to uphold positive levels of trust over time.
