The Effect of Decomposition on the Efficacy of Biometrics for Positive Identification

Biometrics, unique measurable physiological and behavioral characteristics, are used to identify individuals in a variety of scenarios, including forensic investigations. However, data on the longevity of these indicators are incomplete. This study demonstrated that iris and fingerprint biometric data can be obtained up to four days postmortem in warmer seasons and 50 + days in the winter. It has been generally believed, but never studied, that iris recognition is only obtainable within the first 24 hours after death. However, this study showed that they remain viable for longer (2–34 days) depending upon the environmental conditions. Temperature, precipitation, insects, and scavenger activity were the primary factors affecting the retention of biometrics in decomposing human remains. While this study is an initial step in determining the utility of physiological biometrics across postmortem time, biometric research has the potential to make important contributions to human identification and the law enforcement, military, and medicolegal communities.     

Vacuum metal deposition: visualisation of gold agglomerates using TEM imaging

Vacuum metal deposition (VMD) is a well-established technique that can be used for the development of latent fingermarks on a range of polymer surfaces, including polyethylene (PE) bags exposed to harsh environmental conditions. The technique has also proved to be effective on difficult semi-porous surfaces such as the polymer banknotes in circulation in Australia and in an increasing number of other countries. VMD is a two-stage technique. In the first stage, a small amount of gold is deposited under high vacuum onto the exhibit. This is then followed by the deposition, onto the gold layer, of a much thicker layer of zinc. Normal VMD development is characterised by zinc depositing all over the surface except on the fingermark ridges themselves. A phenomenon of reverse development (zinc on the ridges but not on the surface) has been reported by many authors. Recent studies indicated that this phenomenon might occur on low-density polyethylene (LDPE) when the amount of deposited gold is above an optimum quantity. The results suggested that the size of the gold agglomerates formed on the surface of the polymer plays a critical role. This preliminary study was aimed at visualising, by transmission electron microscopy (TEM), the formation of gold agglomerates on polymer surfaces to gain an appreciation of how the density and size of these agglomerates changes with an increasing amount of evaporated gold.     

Critical Pedagogy in the Neoliberal University: Reflections on the 2015 York University Strike through a Marcusean Lens

Abstract

In this article, we see the month-long graduate student and contract faculty strike at York University (Toronto, 2015) through a lens informed by Herbert Marcuse’s thought. In the context of widespread student protests across North America against neoliberal austerity, we draw on our picket line experiences to argue that Marcuse’s work provides insights into how students and faculty can engage in critical praxis within the neoliberal university. We argue that CUPE 3903, the union of TAs and contract faculty at York, is a kind of counter-institution that Marcuse argued was necessary for liberation. Marcuse strategically urged students to take advantage of gaps or cracks in a disintegrating system. Our analysis revolves around the complex experience of the graduate student picket lines – a “gap” – as a site of rupture for the liberation of aesthetic experience, “organized spontaneity,” open, democratic organization, as well as conflict.     

Students’ Feelings of Safety,Exposure to Violence and Victimization,and Authoritative School Climate

Although many students feel unsafe at school, few malleable factors have been identified to increase students’ feelings of safety. Drawing on criminological behavior control theories, this study posits authoritative school climate as one such factor. With data from two nationally representative datasets, this study uses path analysis to examine the relationship between authoritative school climate and feelings of safety, as well as the extent to which this relation is explained by exposure to violence and victimization. Across both datasets, a more authoritative school climate was associated with increased feelings of safety at school. Both models also indicated that this relationship was explained in part by reduced exposure to violence and victimization, although the strength of this indirect effect varied across models. These findings suggest that strengthening students’ relationships with adults and increasing the fairness and consistency of rules in the school may both reduce exposure to violence and victimization and help students feel safer at school.     

Forms of Authority Beyond the Neoliberal State: Sovereignty,Politics and Aesthetics

Critical legal scholarship has recently turned to consider the form, mode and role of law in neoliberal governance. A central theme guiding much of this literature is the importance of understanding neoliberalism as not only a political or economic phenomenon, but also an inherently juridical one. This article builds on these conceptualisations of neoliberalism in turning to explore the wider historical, cultural and sociological contexts which inform the production of neoliberal authority. The papers in this collection were first presented at the symposium ‘Forms of authority beyond the neoliberal state’, held at the Griffith Law School in December 2017. They consider the role of the corporation, the site of the university, the politics of debt, the genre of prestige television, and the archic sources of state violence, in order to imagine forms of authority which lie beyond neoliberalism as an ideology and a set of practices, and the ensemble of institutions which constitute the neoliberal state. The contributions draw on social theory, philosophy, cultural studies, legal geography and political theology in exploring new possibilities for cultivating judgement through and beyond the sovereign, political and aesthetic terrains of neoliberal governance.     

State Power,the Politics of Debt and Confronting Neoliberal Authoritarianism

As an intellectual, economic, political and legal project, neoliberalism is not directed towards the rolling back of the state as an aim in itself. While its deregulatory tendencies, its commodification of public services and the undermining of systems of social welfare superficially suggest a generalised reduction in state power, it has been clear from the early 1980s that one of neoliberalism’s primary concerns has been the authoritarian reshaping of state power to engineer particular social outcomes, whether in criminal justice, the disciplining of organised labour, the militarisation of national territory and migration, or the extension and deepening of regimes of austerity. This article introduces the recent work of Maurizio Lazzarato, who has argued that the asymmetrical creditor-debtor relationship is now the archetype of contemporary, neoliberal social relations. Ultimately, Lazzarato’s perspective tends to exaggerate the totalising powers of finance capital and leads him to endorse a form of political voluntarism, which fails to address the role of the neoliberal state as a site for forms of authoritarianism which are not solely generated by the debt relation. As a response, it will be suggested that aspects of Nicos Poulantzas’s concept of ‘authoritarian statism’ can be used to both strengthen our understanding of the authoritarian characteristics of the neoliberal state, and to imagine possibilities for resisting its expressions of power.     

Start-EU-up! Lessons from international incubation practices to address the challenges faced by Western European start-ups

Despite the continued efforts of policy makers, Western European start-ups are still struggling. Further, as questions are being raised about the effectiveness of incubators, there is a growing call for incubators around the world to learn from each other and improve themselves. Our paper enables Western European incubators to learn from their foreign peers by qualitatively exploring the challenges faced by Western European start-ups and the practices that incubators around the world use to address these challenges. Our study thereby takes a two-step approach. First, using the components of the entrepreneurial ecosystem to structure data coming from 90 qualitative interviews with Western European entrepreneurs and incubator managers, we explore five interrelated challenges that constrain the ability of Western European start-ups to grow into high-impact businesses. In the second part of our study, we conduct a total of 191 interviews in Silicon Valley, the greater Boston area, Israel and Australia to identify practices that incubators in these regions use to address the five challenges identified in the first study. Our findings suggest that, rather than addressing the underlying institutions that cause challenges in the entrepreneurial ecosystem, incubators provide symptomatic solutions by creating an environment that protects start-ups from unfavorable institutions. Accordingly, we conclude that existing incubators have only limited potential to strengthen entrepreneurial ecosystems, and we end our paper with a call for a new generation of ‘systemic incubators’ that aim to transform or create institutions to address the institutional challenges that constrain start-up activity.
