Automated Texture Recognition of Quartz Sand Grains for Forensic Applications*

Quartz sand surface texture analysis has been automated for the first time for forensic application. The derived Basic Image Features (BIFs) provide computer-generated texture recognition from preexisting data sets. The technique was applied to two distinct classification problems; first, the ability of the system to discriminate between (quartz) sand grains with upturned plate features (indicative of eolian, global sand sea environments) and grains that do not exhibit these features. A success rate of grain classification of 98.8% was achieved. Second, to test the ability of the computer recognition system to identify specific energy levels of formation of the upturned plate surface texture features. Such recognition ability has to date been beyond manual geological interpretation. The discrimination performance was enhanced to an exact classification success rate of 81%. The enhanced potential for routine forensic investigation of the provenance of common quartz sand is indicated.     

Treating offenders with mental illness: a research synthesis

The purpose of this research synthesis was to examine treatment effects across studies of the service providers to offenders with mental illness. Meta-analytic techniques were applied to 26 empirical studies obtained from a review of 12,154 research documents. Outcomes of interest in this review included measures of both psychiatric and criminal functioning. Although meta-analytic results are based on a small sample of available studies, results suggest interventions with offenders with mental illness effectively reduced symptoms of distress, improving offender's ability to cope with their problems, and resulted in improved behavioral markers including institutional adjustment and behavioral functioning. Furthermore, interventions specifically designed to meet the psychiatric and criminal justice needs of offenders with mental illness have shown to produce significant reductions in psychiatric and criminal recidivism. Finally, this review highlighted admission policies and treatment strategies (e.g., use of homework), which produced the most positive benefits. Results of this research synthesis are directly relevant for service providers in both criminal justice and mental health systems (e.g., psychiatric hospitals) as well as community settings by informing treatment strategies for the first time, which are based on empirical evidence. In addition, the implications of these results to policy makers tasked with the responsibility of designating services for this special needs population are highlighted.     

‘Monsters don’t bother me anymore’ forensic mental health service users’ experiences of acceptance and commitment therapy for psychosis

Acceptance and Commitment Therapy for psychosis (ACTp) is an approach that aims to change the relationship an individual with psychosis has with difficult thoughts, emotions and experiences. It promotes the use of acceptance, defusion, mindfulness and focussing on valued outcomes as opposed to struggling with psychotic experiences. This service evaluation project explored service users’ experiences and meanings of ACTp within a medium secure mental health service. Thematic analysis was used to analyse interviews with 10 male service users. Four main themes emerged from the data: ‘Recovery’, ‘Insight’, ‘Developing Skills’ and ‘Accessibility’. Overall, service users viewed their experience of ACTp positively and identified encouraging therapeutic outcomes. These findings suggest that ACTp is an approach that should be considered a therapeutic option within forensic mental health contexts. These outcomes were compared with previous research findings. Limitations of the study, clinical implications and ideas for future research have been discussed.     

The oil lobby and the energy crisis

Abstract. The energy crisis has produced a confrontation between the federal government and the Canadian oil industry which has significantly reduced the latter's autonomy. This article postulates three hypotheses, which are then explored in the context of the energy crisis: that pressure group influence declines during a crisis situation; that if the crisis necessitates federal-provincial negotiation this tendency is accentuated; and that when facing a serious threat from government action the group under attack will seek to exert its influence as widely as possible. The article goes on to examine the oil industry's various channels of influence — the Senate, the Alberta Conservative caucus, the Alberta Liberal party, informal contacts with Alberta politicians, the Technical Advisory Committee on Petroleum Supply and Demand, and others and concludes that these were inadequate for serving the industry's objectives during the crisis. The speed at which events unfolded during the crisis and the consumer concern that arose led the federal government to respond rapidly, with little advance consultation with the industry or the producing provinces. In the federal-provincial Confrontation that ensued, the industry was excluded from a significant decision-making role. It will now seek to exert more public pressure on the federal government, but it must do so within a new set of rules under which the various levels of government will be more intimately involved in its activities. Sommaire. La crise de l'éergie a produit, entre le gouvernement fédéral et l'industrie canadienne du pétrole, une confrontation qui a réduit considérablement l'autonomie de cette dernière. L'auteur de cet exposé propose trois hypothèses qu'il examine ensuite dans le contexte de la crise de l'énergie, à savoir:que l'influence des groupes de pression diminue dans une situation de crise; que cette tendance s'accentue si la wise oblige à des nègociations fédéralesprovinciales et que, face à une menace sérieuse d'intervention gouvernementale, le groupe attaqué. cherche à exercer une influence aussi large que possible. II examine ensuite les différentes voies d'influence de l'industrie du pétrole:le sénat, le caucus conservateur de I'Alberta, le parti libéral de l'Alberta, les contacts officieux avec des liommes politiques de l'Alberta, le comité technique qui s'occupe de l'offre et de la demande de pétrole et d'autres, pour conclure qu'elles étaient insuffisantes pour permettre à l'industrie d'atteindre ses objectifs durant la crise. La rapidité avec laquelle les événements se sont déroulés pendant la crise et la manifestation des craintes des consommateurs entraînérent une réaction rapide de la part du gouvernement fédéral, sans grande consultation préalable avec l'industrie ou les provinces productrices. Dans la confrontation fédéraleprovinciale qui a suivi, l'industrie a été exclue de toute prise de décision importante. Elle va chercher maintenant à exercer des ressions publiques accrues sur le gouvernement fédéral, mais elle doit se confonner aux nouvelles régles du jeu qui impliquent une plus grande ingérence des différents niveaux de gouvernement dans ses activités.     

What Determines Ethical Behavior in Public Organizations: Is It Rules or Leadership?

Leadership is widely seen as having an important role in fostering ethical conduct in organizations, but the ways in which the actions of leaders intersect with formal ethics regulation in shaping conduct have been little researched. This article examines this issue through a qualitative study of the operation of the “ethical framework” for English local government, which entailed all councils adopting a code of conduct to regulate the behavior of local politicians. Studying local government provides an opportunity to examine how personal and managerial factors combine to influence ethical conduct and to analyze the ways in which ethical leadership is exercised through multiple people in leadership roles (politicians and managers). The article finds that organizations that exhibit consistently good conduct have multiple leaders who demonstrate good conduct but also act to preempt the escalation of problems and thereby minimize the explicit use of ethics regulation.     

Rethinking Caretaker Conventions for Australian Governments

Australia has well‐established conventions for caretaker governments. These conventions regulate how a government should operate once an election is called, and have been documented for some decades. Yet the current conventions date from an era when elections usually produced clear and immediate results. Can our caretaker conventions cope with the emerging reality of indecisive elections and long delays before a new government is confirmed? This paper canvasses the state of Australia's caretaker conventions and offers suggestions for an expanded, contemporary code.     

The Moderating Effect of Criminal Thinking on Certainty of Apprehension in Decisions to Engage in Antisocial Behavior: Replication and Extension

This study explored whether the rational (certainty of punishment) and nonrational (criminal thinking) aspects of antisocial decision‐making interact. A convenience sample of 319 undergraduates (106 men, 213 women) completed a measure of criminal thinking and responded to three fictional vignettes (i.e., cheating on a final examination in a class they were in jeopardy of failing, stealing $50 off a table in a dorm room, and selling marijuana for a friend) at three different levels of risk or certainty of apprehension (50%, 10%, and 1%). Results indicated that participants reported that they would be more likely to engage in antisocial behavior when the certainty of getting caught was low and the level of proactive (P) or reactive (R) criminal thinking was high. An interaction between certainty and criminal thinking was also observed in which the gap between lower and higher criminal thinking respondents grew as the probability of getting caught fell.     

A Preliminary Investigation into the Accuracy of 3D Modeling and 3D Printing in Forensic Anthropology Evidence Reconstruction,

There is currently no published empirical evidence‐base demonstrating 3D printing to be an accurate and reliable tool in forensic anthropology, despite 3D printed replicas being exhibited as demonstrative evidence in court. In this study, human bones (n = 3) scanned using computed tomography were reconstructed as virtual 3D models (n = 6), and 3D printed using six commercially available printers, with osteometric data recorded at each stage. Virtual models and 3D prints were on average accurate to the source bones, with mean differences from ?0.4 to 1.2 mm (?0.4% to 12.0%). Interobserver differences ranged from ?5.1 to 0.7 mm (?5.3% to 0.7%). Reconstruction and modeling parameters influenced accuracy, and prints produced using selective laser sintering (SLS) were most consistently accurate. This preliminary investigation into virtual modeling and 3D printer capability provides a novel insight into the accuracy of 3D printing osteological samples and begins to establish an evidence‐base for validating 3D printed bones as demonstrative evidence.     

On the Trail of the ‘Lions of Islam’: Foreign Fighters in Afghanistan and Pakistan, 1980-2010

This article provides a review of the history of jihadi foreign fighters in Afghanistan over the last 30 years. It details the post-9/11 period and the invasion of Afghanistan by U.S. forces, focusing on the ethnic origin of the foreign fighters and how different groups engaged in different aspects of the conflict. Additionally, the piece explains that while the foreign fighters who came to fight alongside the Taliban in Afghanistan included, among others, Uzbekistanis (not Afghan Uzbeks), Turks, and Arabs, there was also a significant force of Pakistanis—of both Pashtun and Punjabi origins—that joined, bolstering the Taliban army.
