A new perspective in the estimation of postmortem interval (PMI) based on vitreous

The relation between the potassium concentration in the vitreous humor, [K+], and the postmortem interval has been studied by several authors. Many formulae are available and they are based on a correlation test and linear regression using the PMI as the independent variable and [K+] as the dependent variable. The estimation of the confidence interval is based on this formulation. However, in forensic work, it is necessary to use [K+] as the independent variable to estimate the PMI. Although all authors have obtained the PMI by direct use of these formulae, it is, nevertheless, an inexact approach, which leads to false estimations. What is required is to change the variables, obtaining a new equation in which [K+] is considered as the independent variable and the PMI as the dependent. The regression line obtained from our data is [K+] = 5.35 + 0.22 PMI, by changing the variables we get PMI = 2.58[K+] - 9.30. When only nonhospital deaths are considered, the results are considerably improved. In this case, we get [K+] = 5.60 + 0.17 PMI and, consequently, PMI = 3.92[K+] - 19.04.     

Detection of apoptosis in ischemic heart. Usefulness in the diagnosis of early myocardial injury

Myocardial samples of hearts with histologic findings of acute myocardial infarction (group A), sudden coronary deaths without histologic changes (group B), and chronic ischemic heart disease (group C) were analyzed to investigate the appearance of apoptosis in acute and chronic ischemic cardiac disorders. This analysis involved the morphologic detection of DNA strand breaks in myocyte nuclei by the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay and the biochemical determination of DNA laddering in the myocardium using archival formalin-fixed, paraffin-embedded tissue sections of human myocardium. The authors demonstrated that apoptosis of myocardial cells could occur after ischemic myocardial cell injury. In all documented cases of acute myocardial infarction (group A), the infarcted area included extensive presence of both apoptosis and necrosis. In the tissue bordering on and away from the obviously infarcted areas, positive nuclei were intermingled with nonstained normal myocytes. The number of positive nuclei decreased with the distance from the infarction foci. In group B, myocardial samples showed focal or diffuse nuclear positivity of varying degrees for apoptosis, confirming the presence of myocardial ischemic cell death, whereas the histologic diagnosis remained inconclusive. This finding suggests that apoptosis could be used as a marker for acute ischemic injury. In group C, stained nuclei were dispersed with intermingled normal cardiomyocytes.     

Development of a Quality Assurance and Continuous Quality Improvement (CQI) Model in Public Child Welfare Systems

The purpose of this article is to review the development and implementation of a revised quality assurance and continuous quality improvement (CQI) model for the child welfare system in one Mid-Atlantic state, and the contribution of this new process to measuring the quality of child welfare practices. This revised CQI model in the state includes a broader scope of assessing practice and outcomes, as well as compliance, and engages internal and external partners in the process. This study is the first to describe the state’s revised CQI implementation process and examine preliminary outcomes in a statewide child welfare system. Findings indicate that the revised model was able to identify the factors that contributed to improving outcomes for children and families and to develop a greater understanding of the aggregate data across the state. This study will contribute to the comprehensive understanding of the model and provide implications for future quality assurance practices.     

The Australian Experience of Municipal Amalgamation: Asking the Citizenry and Exploring the Implications

Debate over municipal amalgamations in Australian continues to dominate local government reform agendas, with the putative need to achieve economies of scale and scope consistently set against anti‐amalgamation arguments designed to preserve extant communities. Following from an examination of recent episodes of consolidation in Australia, this paper reports on citizens' attitudes to amalgamation garnered from a national survey of 2,006 individuals. We found that generally, citizens are ambivalent toward amalgamation, although attitudes were influenced by particular demographic characteristics and attitudes to representation, belonging, service delivery requirements and the costs thereof. The results suggest that, away from the local government sector itself, structural reform may not be the vexatious issue it is often portrayed as. The implications of this are explored here.     

Guardians of the environment in Canada’s Chemical Valley

Citizens of the Aamjiwnaang First Nation fight for justice with their bodies at the frontlines of daily toxic exposure. This paper examines struggles for environmental and reproductive justice in the polluted heart of Canada’s ‘Chemical Valley’. These are as struggles over life, land and knowledge. Based upon community-engaged qualitative research, from a participatory action research approach, including field immersion, participant observation and 35 in-depth interviews with First Nations residents, I document the Aamjiwnaang First Nation’s citizens’ activities and practices on the ground as they cope with the impact of their contaminated surroundings on their health and habitat. This community-engaged scholarship lens brings into view the lived experiences and ongoing practices of resistance by the Anishinabek citizens who are surrounded by Chemical Valley. I situate these struggles within the green citizenship literature to assess three blind spots of green governmentality: greening citizenship, lifestyle blame and Western dualisms. I discuss the multiple edges of ecological citizenship and argue that citizens are simultaneously bound up within disciplinary power relations and place-based belonging. This place, although polluted, is crucial to practices of relational Anishinabek citizenship and the identity of indigenous citizens who call this place both ‘prison and home’.     

Are regulatory agencies independent in practice? Evidence from board members in Spain

Are the board members of regulatory agencies (regulators), taken as a particular cluster within the public sphere, independent of elected politicians and tenured bureaucrats? How can we assess their independence in practice, beyond formal rules? To address these questions, this paper delves into two key dimensions: board members' social connections and their security of tenure in office. Firstly, we focus on regulators' identity as policy adjudicators and examine their political and administrative relations. In doing so, we expect to understand better how regulators' social and political situations may influence their behavior. Secondly, we assess their political vulnerability through political cycles in order to measure their de facto independence over time. Additionally, variations in these two dimensions are compared with respect to the effect of different de jure appointment rules. We contrast these expectations with the empirical evaluation of board members of regulatory agencies in Spain (1979–2010). Thus, we confirm that regulators who have an administrative profile are more vulnerable to political changes than those with political ties, while appointment rules have an influence on their political vulnerability.     

Corporate Mobility and Company Law

Globalisation has given commercial parties more freedom to choose the company law system that best suits their private needs. The growing range of techniques to facilitate choice between systems of company law reshapes the mandatory/enabling debate in countries where corporate mobility is a relatively new business phenomenon and where the past focus has mostly been on degrees of flexibility within domestic law. This article examines relocations, both out of and into the UK, as a source of learning on market preferences with respect to company law and on vulnerabilities. It considers the wider policy implications for the development of company law of more freedom of choice between company law systems. It concludes with a call to explore the potential for more optionality within company law to counter the rise of choice between systems of company law.     

The testosterone/cortisol ratio moderates the proneness to anger expression in antisocial and borderline intimate partner violence perpetrators

Several studies have provided evidence that antisocial, borderline and narcissistic personality traits of intimate partner violence (IPV) perpetrators significantly increase proneness to violence. In addition, an imbalance between testosterone (T) and cortisol (C) levels has been observed in this population, making individuals prone to violence. We aimed to establish whether IPV perpetrators differ in personality traits, T/C ratio and anger expression from controls, and also to examine the moderating role of the T/C ratio in the relationship between personality traits and anger expression. The sample consisted of 16 IPV perpetrators and 20 controls. T/C ratio was obtained as the quotient between salivary T and C levels. Anger expression and personality traits were measured with STAXI-2 and MCMI-III, respectively. Our results indicate that IPV perpetrators have higher antisocial, borderline and narcissistic personality traits and anger expression than controls. Nonetheless, they did not differ in basal T/C ratio. Finally, only in IPV perpetrators there was a positive relationship between these variables, the T/C ratio playing a moderating role in the relationship of antisocial and borderline traits with anger expression. In IPV perpetrators the T/C ratio may explain why certain personality traits are associated with high risk of becoming violent.     

Green Activist Criminology and the Epistemologies of the South

Since its inception, green criminology has attempted to highlight instances of environmental degradation and destruction, as well as examine and analyse the causes thereof and contemplate the responses thereto. Efforts to reduce environmental crime and curb environmental harm, more generally, have not gone unimpeded, however. Activists around the world are being killed in record numbers trying to defend their land and protect the environment. In this article, I consider the role of socially engaged scholars who reject the idea or ideology of ‘neutral scientists’ in light of the risks faced by environmental defenders. As such, this article replies to the claims that activism and the production of knowledge must be clearly separated. To do so, this article draws upon examples from Latin America to underscore the importance of an ‘activist criminology’ (Belknap in Criminology 53(1):1–22. doi: 10.1111/1745-9125.12063, 2015) attuned to environmental harms and injustices perpetrated on those seeking to prevent the despoliation of the Earth.
