Radiographic age estimation based on degenerative changes of vertebrae

Age estimation is an important component of decedent identification. When assessing adult remains, anthropologists frequently use gross examination of skeletal elements, such as clavicles, ribs, and pubic symphyses. For fleshed bodies, this requires the removal of these elements and maceration prior to analysis. A new method was developed using radiographic imaging to estimate age from degenerative changes of the lower thoracic and upper lumbar vertebrae. This technique will complement anthropological age estimation methods in young and middle-aged adults and may serve as a stand-alone method for older individuals. Digital radiographs from 240 medical examiner cases were evaluated. The sample included 120 females and 120 males between the ages of 18 and 101 years. A 3-phased scoring system was used for the target vertebrae. Transition analysis was conducted on binned average scores and a Bayesian approach was used to assign age intervals. At the 90% credible interval, individuals in Bin 1 were under 36 years of age while those in Bin 3 were over 47 years of age. Individuals in Bin 2 showed too much age variation to be informative. No significant differences were found between males and females. These findings will be especially useful in the age estimation of older adults and may eliminate the need for skeletal sampling in medicolegal cases where advanced degenerative changes are radiographically observed in the lower thoracic and/or upper lumbar vertebrae. This method was developed for use on fleshed individuals but may also be applicable to skeletonized remains.     

Quantitative intersectionality: Imperatives and opportunities for advancing social equity

Social equity is a pillar of public administration (PA), yet its actualization remains elusive. The path forward to closing persistent social equity gaps requires the utilization of quantitative intersectionality in PA. This article explores the literature related to quantitative intersectionality and the imperative for use in the scholarship and practices of PA. To exemplify this concept in practice, we present a case study examining Vocational Rehabilitation performance data reports. Findings illustrate how quantitative intersectionality provides an opportunity to unpack overlapping identities for people with disabilities whose individual characteristics include historically oppressed race/ethnicity and gender identities. Findings assert the imperative for using quantitative intersectionality to achieve social equity for all.     

Medium‐Chain Acyl‐CoA Dehydrogenase Deficiency in Adulthood: A Potential Diagnosis in a Patient with Mental Status Changes Suspected of Drug Toxicity

Medium‐chain acyl‐CoA dehydrogenase (MCAD) deficiency is a rare but important component of the differential diagnosis for adults with a history of premortem mental status changes and the postmortem finding of hepatic steatosis. This case report describes a 30‐year‐old white man who, following a period of nausea and vomiting, was admitted to the hospital with sudden mental status deterioration followed rapidly by clinical deterioration and death. Treating physicians in this case suspected acute illicit drug toxicity with synthetic cathinones based on social history. Clinicians and medical examiners should be aware that the presentation, signs, and symptoms described may indicate an underlying inborn error of metabolism such as MCAD deficiency and take action accordingly.     

The specter of racism: exploring White racial anxieties in the context of policing

The connection between policing and whiteness remains an undertheorized area of police studies. In this article, I explore ordinary policing behaviors through the lens of critical whiteness studies in an effort to understand how White police officers actively make, or fail to make, meaning of race in the context of their work. Drawing on ethnographic work with three police departments in the Midwest, I describe the racial anxieties and insecurities White officers express at the possibility of being viewed as engaging in racializing behaviors. Of particular interest is the power of the crime control focus orienting everyday policing practice in displacing attention from the many ways race, and particularly whiteness, matters in policing. I conclude by discussing the implications this line of inquiry holds for making discussions about the role of white privilege in policing more productive.     

Ability to Face Threats of Cyberterrorism: Factors Associated with Organizational Competence

ABSTRACT

Acts of cyberterrorism represent potential, significant negative effects to property, infrastructure systems, security, and an overall way of life. These disruptions garner significant attention from government and the public. Managers concerned by threats of cyberterrorism should understand the components that enhance organizational competence so that doubt and fear do not overtake organizational members when faced with such extreme events. Although organizational competence is important in everyday organizational behaviors, the presence of confidence in organizational abilities is especially critical when operating in the midst of the ambiguity and destructive disruptions associated with cyberterrorist threats. We empirically assess three factors associated with competence for organizations facing simulated cyberterror attacks. Our results support the relationship between two of these factors—organizational identification and deference to expertise—with organizational competence. These findings contribute to research concerning the antecedents critical to organizational competence and also add to the growing research on cyberterrorism.     

Dynamics of Unfree Labour in the Contemporary Global Economy

This short introduction to the symposium sets the context for the collection of articles, locating them in debates about labour conditions in the global economy. It outlines the two central questions which animate the symposium. First, what forms do unfree labour take in the contemporary global economy, and what are the implications for the most vulnerable workers in diverse contexts? Second, which processes, conditions and dynamics generate and facilitate unfree labour, and which theoretical and analytical perspectives do we need in order to understand them? It summarises some of responses to these questions which emerge in the collected articles, and highlights their contributions to the task of advancing fresh ways of thinking about unfree labour.     

Body Politics with Feeling: The Power of the Clothesline Project

The Clothesline Project uses t-shirt art to address the issue of violence against women. Others have argued that the Clothesline Project empowers women in general and female victims of violence in particular. In this article we attempt to deepen this argument, first, by tying it to the existing "faces of power" literature. Using this literature, we argue that the Clothesline Project empowers by creating a public space for political action, offering an alternative communicative medium, educating in a context of dismissal and silence, and contributing to social and cultural transformation. Second, we develop the notion of affective power and argue that it amplifies the practical power of the Clothesline Project.     

A Comparison of Fingerprint Sweat Corrosion of Different Alloys of Brass

Fingerprint sweat from 40 donors was deposited onto samples of five α and α + β phase brasses, comprising five alloys with different copper and zinc concentrations, two of which also had the addition of small concentrations of lead. Visual grading of the visibility of the corrosion revealed that brasses with the least amount of zinc produced the most visible and fully formed fingerprints from the most donors. Consideration of previously reported mechanisms for the corrosion of brass suggests red copper (I) oxide as a likely corrosion product for low zinc brasses, and a consideration of the color, composition, and solubility of fingerprint sweat corrosion products suggests that copper (I) oxide produces good contrast and visibility with the brass substrate. Scanning electron microscope images of the corrosion of all five alloys confirmed the enhanced contrast between corroded and uncorroded areas for low zinc alloys.     

The advice lawyers give themselves: the Canadian Bar Association's campaign for timekeeping in the mid-twentieth century

This paper is a historical analysis of how the Canadian organized bar urged lawyers to adopt strict timekeeping practices and use time as the basis for their legal fees. The Canadian Bar Association's compilation of data on the legal profession in the late 1940s–the collection of ‘facts’, the ‘scientific’ nature of this collection–foreshadowed the way that the organized bar would couch its advocacy for the practice of timekeeping in the 1970s. The pioneering experts on law office management in Canada promised lawyers significant profit increases and gave minimal attention to the relationship between legal fees and client's interests.
