Reliability of a two-dimensional footprint measurement approach

Although footprint evidence can be taken from the scene of a crime, the science underpinning such measurement in forensic science has not been fully explored.A literature search revealed various measuring approaches, all of which demonstrated either little or no measurement rigour in terms of reliability. The aim of this study was to apply a robust measurement approach for testing the reliability of two-dimensional footprint impressions.Three dynamic and three static footprints were taken from the right foot of thirty female and thirty one male volunteers using the ‘Inkless Shoeprint Kit’. The images were digitised. Lengths, widths and angles were measured using a selection of currently employed methods.An investigation of the reliability of the chosen measuring method suggested high intra-rater agreement: for example, the length measurement suggested an intraclass correlation coefficient (ICC) 0.99, 95% Confidence Interval (CI) ? 0.28 to 0.01, standard error of measurement (SEM) 0.07, Limits of Agreement (LOA) ? 0.91 to 0.65.Inter-rater reliability between three operators was also high: SEM ranged from 0.05 mm to 0.07 mm, ICC 0.99.Our study has established a reliable two-dimensional measuring technique that could be used for footprint comparison in further research.     

Academic entrepreneurship and business schools

In this paper, we employ resource-based and institutional theories to examine the current role of business schools in academic entrepreneurship. In particular, we seek to identify and understand the challenges to business schools contributing to the transfer of knowledge to enable academic entrepreneurship. Employing a case-based method, we present evidence from 42 interviews with technology transfer officers (TTOs), business school deans, business school entrepreneurship faculty and scientists in eight UK universities. Our empirical analysis is focused on analyzing the challenges arising from the links between business schools and three other principal stakeholders of academic entrepreneurship (i.e., the university management, TTOs and academics in science departments). The findings suggest that in addition to concerns about the nature of their human capital, the ability of business schools to fill knowledge gaps in the development of academic entrepreneurship is constrained by the institutional structures of universities which influence: the strategies of the university and the business school; links between business schools, TTOs and scientists; and process issues relating to differences in language and codes, goal differences, incentives and rewards, expertise differences and the content of interactions. We conclude that if business schools are to play a more prominent role in academic entrepreneurship there is a need to develop internal university processes and policies that promote rather than hinder internal knowledge flows between business schools, TTOs and science departments.     

Legal Accountability in the Service-Based Welfare State: Lessons from Child Welfare Reform

Current trends intensify the longstanding problem of how the rule of law should be institutionalized in the welfare state. Welfare programs are being redesigned to increase their capacities to adapt to rapidly changing conditions and to tailor their responses to diverse clienteles. These developments challenge the understanding of legal accountability developed in the Warren Court era. This article reports on an emerging model of accountable administration that strives to reconcile programmatic flexibility with rule-of-law values. The model has been developed in the reform of state child protective services systems, but it has potentially broad application to public law. It also has novel implications for such basic rule-of-law issues as the choice between rules and standards, the relation of bureaucratic and judicial control, the proper scope of judicial intervention into dysfunctional public agencies, and the justiciability of "positive" (or social and economic) rights.     

Lessons learned from inter-laboratory studies of carbon isotope analysis of honey

Forensic application of carbon isotope ratio measurements of honey and honey protein to investigate the degree of adulteration with high fructose corn syrup or other C₄ plant sugars is well established. These measurements must use methods that exhibit suitable performance criteria, particularly with regard to measurement uncertainty and traceability – low levels of adulteration can only be detected by methods that result in suitably small measurement uncertainties such that differences of 1‰ or less can be reliably detected. Inter-laboratory exercises are invaluable to assess the state-of-the art of measurement capabilities of laboratories necessary to achieve such performance criteria. National and designated metrology institutes from a number of countries recently participated in an inter-laboratory assessment (CCQM-K140) of stable carbon isotope ratio determination of bulk honey. The same sample material was distributed to a number of forensic isotope analysis laboratories that could not participate directly in the metrological comparison. The results from these studies have demonstrated that the majority of participants provided isotope delta values with acceptable performance metrics; that all participants ensured traceability of their results; and that where measurement uncertainties were reported; these were fit-for-purpose. A number of the forensic laboratories only reported precision rather than full estimates of measurement uncertainty and this was the major cause of the few instances of questionable performance metrics. Reporting of standard deviations in place of measurement uncertainties is common practice outside metrology institutes and the implications for interpretations of small differences in isotopic compositions are discussed. The results have also highlighted a number of considerations that are useful for organisers of similar inter-laboratory studies in the future.     

Cryptocurrencies are (smart) contracts

The functioning of cryptocurrencies like Bitcoin ultimately depends on participants’ agreements to selectively disclose or conceal information. Various arguments suggest that those agreements amount to a large multilateral contract to which all participants are parties. That multilateral agreement is automatically enforced through smart contract technology. Therefore, cryptocurrency “wallet holders” are simultaneously creditors and debtors of smart contract claims vis-à-vis their cryptocurrency community.     

The Distorted Jurisprudential Discourse of Nazi Law: Uncovering the ‘Rupture Thesis’ in the Anglo-American Legal Academy

It has been remarked that the ‘rupture thesis’ prevails within the Anglo-American legal academy in its understanding of the legal system in Nazi Germany. This article explores the existence and origins of this idea—that ‘Nazi law’ represented an aberration from normal legal-historical development with a point of rupture persisting between it and the ‘normal’ or central concept of law—within jurisprudential discourse in order to illustrate the prevalence of a distorted (mis)representation of Nazi law and how this distortion is manifested within the discourse today. An analysis of the treatment of Nazi law in two major 50th anniversary publications about the 1958 Hart–Fuller debate, and a review of representations of the Third Reich within literature from the current discourse, demonstrates that the rupture thesis continues to be reproduced within jurisprudence. An examination of the role of Nazi law in the Hart–Fuller debate itself shows that it can be traced back to the debate, where it was constructed through a combination of conceptual determinism and historical omission. It concludes that the historical Nazi law has great significance for the concept of law, but neither positivism nor natural law has properly theorised the nature of the real Nazi legal system.     

The impact of an intensive inpatient violent offender treatment programme on intermediary treatment targets,violence risk and aggressive behaviour in a sample of mentally disordered offenders*

This study examined the impact of an intensive inpatient violent offender treatment programme, Life Minus Violence-Enhanced (LMV-E), on intermediary treatment targets, risk for violence, and aggressive behaviour during treatment in a sample of male mentally disordered offenders. Using quasi-experimental design, offenders who completed LMV-E and a comparison group showed reduced problems with impulsivity and anger regulation and improvements in social problem solving. Aggregate risk for future violence lessened in both treatment and comparison groups, although by a significantly greater degree for the comparison group. The aggressive behaviour of both groups reduced. Completion of the LMV-E conferred additional improvements in some facets of social problem solving and anger regulation. Neither group showed improvements in empathic responses, coping skills or problematic interpersonal style. Overall, these results suggest anger regulation, impulsivity and social problem solving are most amenable to change, that reductions in certain facets of these dynamic risk factors transpires with nonspecific psychiatric inpatient treatment, but that the LMV-E, a cognitive behavioural violence specific psychological treatment, confers greater change in some facets of social problem solving and anger regulation.     

Elite Interactions and Voters’ Perceptions of Parties’ Policy Positions

Recent research documents that voters infer that governing coalition partners share similar ideologies, independently of these parties’ actual policy statements. We argue that citizens estimate party positions from more general forms of interparty cooperation and conflict, particularly near the times of national elections. We analyze tens of thousands of media reports on elite interactions from 13 Western democracies between 2001 and 2014, and show that—controlling for coalition arrangements and for the policy tones of parties’ election manifestos—voters infer greater left–right agreement between pairs of parties that have more cooperative public relationships, but that this “cooperation effect” is only evident near the times of national elections. Our findings have implications for parties’ policy images and for mass–elite linkages.
