Potential and pitfalls in establishing the provenance of Earth-related samples in forensic investigations

Earth scientists are often asked to establish or constrain the likely provenance of very small quantities of earth-related material as part of a forensic investigation. We tested the independent and collective interpretations of four experts with differing analytical skills in the prediction of sample provenance for three samples from different environmental settings. The methods used were X-ray diffraction, scanning electron microscopy, the assessment of pollen assemblages, and structural characterization of organic matter at the molecular level. Independent interpretations were less accurate than those where multiple techniques were combined. Collective interpretation was very effective in the assessment of provenance for two of the three sites where the mineralogy and plant communities were distinctive. At the other site, although the mineralogical analysis correctly identified the Triassic mudstone soil parent material, Carboniferous spores from domestic coal were initially interpreted as deriving directly from bedrock. Such an interpretation could be a common pitfall owing to anthropogenic redistribution of material such as coal.     

A cross‐cultural comparison of the self‐concepts of imprisoned young offenders by country,race, and parental status

The Tennessee Self‐Concept Scale (TSCS) was administered to 193 imprisoned male youthful offenders in a southern U.S. state and to 161 male young offenders in one of Her Majesty's young offender institutions in England. The purpose of the study was to determine if the self‐concept scores of the subjects differed significantly according to the subject's ethnicity (Country), whether the youth resided with one or both parents or separate from either parent (Parental Status Residence) at the time of imprisonment, and Race. Analyses reveal the Total Self Concept scores of the U.S. and English offenders, as well as the sub‐scale scores, which together make up the Total Self Concept score, are significantly lower than for normal subjects. The U.S. offenders’ scores were more abnormal than the English offenders, often falling below the lowest normal range score, in some instances so low as to suggest serious psychopathological conditions. Discriminant function (DF) analysis was used to analyze the effects of the 12 self‐concept measures in distinguishing subjects by Country, Race, and Parental Status. Analyses correctly classified group membership more than two thirds of the time for each of the three variables and produced moderate to strong correlation coefficient values for various sub‐scales on each of the three variables. Black subjects in both cultures were found to score significantly lower than their White counterparts, a finding that contradicts numerous earlier studies. Findings also question the labeling theory proposition that the stigma of delinquency and subsequent imprisonment with other delinquents exacerbates one's negative regard of self. And perhaps more important, the findings suggest that cultural influences in both countries, rather than the effects of the stigma of the delinquent label and imprisonment, operate to cause low‐self‐concept long before one becomes involved in the justice system. Findings also reveal that delinquent youths from intact families have significantly higher self‐concepts than those from fragmented families.     

Predicting Property Crime Risk: an Application of Risk Terrain Modeling in Vancouver,Canada

Research on the spatial dimension of crime has developed significantly over the past few decades. An important aspect of this research is the visualization of this dimension and its underlying risk across space. However, most methods of such visualization, and subsequent analyses, only consider crime data or, perhaps, a population at risk in a crime rate. Risk terrain modeling (RTM) provides an alternative to such methods and can incorporate the entire environmental backcloth, data permitting. To date, the RTM literature has dominantly focused on violent crime in the United States. In this paper, we apply RTM to property crime victimization (residential burglary) in Vancouver, Canada. We are able to show that not only does RTM have applicability in a Canadian context but provides insight into nonviolent victimization.     

Public Sector ‘Modernisation’: Examining the Impact of a Change Agenda on Local Government Employees in England

Can public sector reform change service performance for the better? This is a hotly contested debate that carries significant theoretical and practical importance. In England, as in many countries, modernisation was at the heart of local government reform and represented an interpretation of New Public Management into a policy framework. This paper examines the role of the modernisation change agenda in England and what this has subsequently meant for ‘service improvement’. Drawing on both document analyses and qualitative interviews with local government employees, we find that while modernisation sought to establish continuous improvement, unintended consequences of modernisation have led to Staff Reductions, Skill Deficiencies, and Loss of a Competent Middle Core in local government, as well as performance outcomes creating an environment for Commissioning, Service Reduction, and Self‐Policing. Implications for the lasting roles and behaviours of public managers affected by this national change agenda are discussed, and conclusions for theory and practice are drawn.     

Congress and the political expansion of the U.S. districts courts

Expanding the number of U.S. district judgeships is often justifiedas a response to expanding caseloads. Increasing judgeshipsduring unified government, however, allows Congress and thePresident to engage in political (patronage and ideological)control of the federal district courts. This paper examinesempirically the relative importance of caseload pressure andpolitical motives for Congress to expand the number of federaldistrict judgeships. We demonstrate that politics dominatesthe timing of judgeship expansion in the U.S. District Courts.We also show that both politics and caseload affect the actualsize of those timed expansions. In particular, we find thatbefore 1970, Congress seemed to have strong political motivationsfor the size of an expansion. After 1970, Congress became muchmore attentive to caseload considerations.
