Evaluation and applicability of Alere iCup DX 14 for rapid postmortem urine drug screening at autopsy

Performing point‐of‐care urine drug screen testing at autopsy by a forensic pathologist may provide an early indication of the presence of analytes of interest during autopsy. An evaluation for the screening of 14 classes of common drugs of abuse in postmortem urine by the point‐of‐care screening device, Alere iCup DX 14, is presented. One hundred ninety postmortem urine samples were screened with the iCup occurring at autopsy by the forensic pathologist. Positive and negative results obtained from the screening kit were evaluated against confirmatory test results obtained using routine forensic toxicology analyses that employed LC‐MS/MS and GC‐MS to detect a combination of over 85 common drugs of abuse and medications. Sensitivity for each respective iCup drug class ranged from 66% (buprenorphine) to 100% (methadone, tricyclic antidepressants). Specificity for each respective iCup drug class ranged from 89% (benzodiazepines) to 100% (amphetamines, barbiturates, buprenorphine, 3,4‐methylenedioxymethamphetamine, methadone). Positive predictive values ranged from 44% (benzodiazepines) to 100% (amphetamines, barbiturates, buprenorphine, methylenedioxymethamphetamine, methadone), while negative predictive values ranged from 96% (methamphetamine) to 100% (barbiturates, methadone, tricyclic antidepressants). A high false‐positive rate was yielded by the benzodiazepine class. The lack of fentanyl screening in the point‐of‐care device is a significant limitation considering its prolific prevalence in forensic casework. The results obtained in the study should be acknowledged when considering the use of the Alere iCup DX 14 in the context of postmortem casework to help indicate potential drug use contemporaneously with autopsy and when requiring such preliminary results prior to the release of a final forensic toxicology report.     

The Influence of Emotional Labor and Emotional Intelligence on Job Performance: Does Ownership Type Matter? A Comparison of Public and Private Organizations in China

ABSTRACT

Given the limited knowledge about the effect of contextual factors of organizational ownership types on emotional labor, this research addresses two main questions: (1) whether emotional labor varies among organizations with different ownership types; and (2) whether emotional labor and emotional intelligence relate to job performance in different ways in public and private organizations. This paper examines the research questions with 306 self-report questionnaires from the public sector, domestic privately-owned enterprises and foreign-invested firms in China. Significant differences were found in the emotional labor reported in public and private organizations. Overall, emotional labor was found to have a significant effect on in-role performance, and emotional intelligence moderated the link between emotional labor and job performance in public organizations, but not in private organizations.     

Can a leopard change its spots? Strategic behavior versus professional role conception during Ukraine's 2014 court chair elections

Do judges respond to institutional and strategic incentives or do they strictly follow dominant professional role conceptions? This article weighs in by exploring whether an ideational shift toward judicial empowerment and independence can germinate from institutional reforms. Ukraine's 2014 Euromaidan revolution and the comprehensive judicial reform adopted in its wake provide a test of the competing theoretical accounts. A judicial lustration law sacked all incumbent court chairs, who had been appointed by the executive, and gave Ukrainian judges the right to elect new chairs via secret ballot. I analyze this radical step toward judicial self-government using an original data set with individual- and court-level data. The key finding is that less than a fifth of Ukrainian judges embraced their newly granted agency and elected a new chair for their court, whereas the overwhelming majority followed dominant professional norms of deference and reelected the sacked court chairs. This finding holds for all rungs of the judicial hierarchy and for all regions of Ukraine. Even protégés of ousted president Yanukovych won the secret ballot vote by their peers more often than they lost it. Beyond Ukraine, these results suggest that empowering individual judges in the highly hierarchical structure of a civil law judiciary is unlikely to lead to a judicial behavior shift, at least in the short run.     

The ‘Regulatory State’ in Higher Education: Assuring Quality through New Modalities of Control in Brazil

The Brazilian Higher Education (HE) sector, following a global trend of rapid transformation, has undergone marked changes over the past two decades. These changes have involved the design of quality assurance tools as instruments for regulatory governance. In presenting an overview of the recent history and characteristics of quality assurance in the Brazilian HE sector, this paper contextualises the Brazilian experience according to broader conceptual frameworks and discusses how and why regulatory governance in this sector has so radically changed.     

Measuring Ethnic Fractionalization in Africa

In most studies of the impact of ethnic diversity on economic growth, diversity is hypothesized to affect growth through its effect on macroeconomic policies. This article shows that most measures of ethnic diversity (including the commonly used ELF measure) are inappropriate for testing this hypothesis. This is because they are constructed from enumerations of ethnic groups that include all of the ethnographically distinct groups in a country irrespective of whether or not they engage in the political competition whose effects on macroeconomic policymaking are being tested. I present a new index of ethnic fractionalization based on an accounting of politically relevant ethnic groups in 42 African countries. I employ this measure (called PREG, for P olitically R elevant E thnic G roups) to replicate Easterly and Levine's influential article on Africa's "growth tragedy." I find that PREG does a much better job of accounting for the policy-mediated effects of ethnic diversity on economic growth in Africa than does ELF.     

Homicidal hanging

We report a case of homicide by hanging of a 29-year-old woman that was committed by her husband, who nearly escaped from justice. We offer some reflections on the rarity of this method of mechanical asphyxia in cases of homicide, and on the difficulties in the diagnosis of the medico-legal etiology of these situations. We also offer a short review of similar cases in the medico-legal literature.     

Determination of length of human long bones of hands from their fragments

In cases of fragment/broken long bones, it becomes difficult to measure the length of bones for the purpose of calculation of total height (stature) of the individual with the help of magnification factors. An attempt has been made to devise a method of calculating the bones length from fragments on three long bones of the upper extremity.
