A Computational Framework for Age‐at‐Death Estimation from the Skeleton: Surface and Outline Analysis of 3D Laser Scans of the Adult Pubic Symphysis

In forensic anthropology, age‐at‐death estimation typically requires the macroscopic assessment of the skeletal indicator and its association with a phase or score. High subjectivity and error are the recognized disadvantages of this approach, creating a need for alternative tools that enable the objective and mathematically robust assessment of true chronological age. We describe, here, three fully computational, quantitative shape analysis methods and a combinatory approach that make use of three‐dimensional laser scans of the pubic symphysis. We report a novel age‐related shape measure, focusing on the changes observed in the ventral margin curvature, and refine two former methods, whose measures capture the flatness of the symphyseal surface. We show how we can decrease age‐estimation error and improve prior results by combining these outline and surface measures in two multivariate regression models. The presented models produce objective age‐estimates that are comparable to current practices with root‐mean‐square‐errors between 13.7 and 16.5 years.     

INTERORGANIZATIONAL UTILITY OF WELFARE STIGMA IN THE CRIMINAL JUSTICE SYSTEM*

The appropriation of “welfare stigma” or stereotypes about poor people's overreliance and abuse of public aid in two core criminal justice functions is examined: felony adjudication in a court system and space allocation in a jail. Through a comparative ethnographic study in which an abductive analysis of data (20 months of fieldwork) was used, we show that criminal justice gatekeepers utilize welfare stigma to create stricter eligibility criteria for due process in criminal courts and occupancy in jails. Specifically, the number of court appearances, motions, trials, jail beds, food, showers, and medical services is considered by professionals to be the benefits that individuals seek to access and abuse. Professionals view their role as preventing (rather than granting) access to these resources. The comparative nature of our data reveals that welfare stigma has interorganizational utility by serving two different organizational goals: It streamlines convictions in courts, which pulls defendants through adjudication, and conversely, it expands early release from jails, which pulls inmates out of the custody population. In the context of diminishing social safety nets, our findings have implications for understanding how discretion is exercised in an American criminal justice system increasingly tasked with the distribution of social services to the urban poor.     

Is It the What or the How? The Roles of High‐Policing Tactics and Procedural Justice in Predicting Perceptions of Hostile Treatment: The Case of Security Checks at Ben‐Gurion Airport,Israel

What affects perceptions of hostile treatment by police, characterized by feelings such as humiliation and intimidation? Is it what the police do to the citizen, or is it about how they do it? The important effects of procedural justice are well documented in the policing literature. Yet, it is not clear how high‐policing tactics, coupled with procedural justice, affect one's sense of hostile treatment: is it the case that what the police do does not matter as long as they follow the principles of procedural justice, or do some invasive or unpleasant tactics produce negative emotions regardless of the amount of procedural justice displayed by the officer? In the present study we examine this question in the context of security checks at Ben‐Gurion Airport, Israel. Using a survey of 1,970 passengers, we find that the behavioral elements of procedural justice are an important antidote, mitigating the negative effects of four “extra” screening measures on the perceived hostility of the checks. At the same time, two security measures retain an independent and significant effect. We discuss the implications of our findings and hypothesize about the characteristics of policing practices that are less sensitive to procedural justice.     

Brexit,Article 50 and the Contested British Constitution

This article discusses the early stages of the Art 50 TEU process, and those aspects that relate most clearly to British constitutional law. Its overarching theme is that the Brexit process is rendered highly problematic by the lack of any coherent conception of the British Constitution. Different parties settle on interpretations of constitutional law that support their case, but often there is no determinative answer. Three broad issues are examined in order to substantiate this claim: the EU Referendum, the triggering of Article 50, and the Devolution aspect of Brexit. I argue that each of these issues reveals tensions and competing constitutional interpretations that suggest that the British Constitution is ill‐equipped to deal with Brexit.     

Is the Expert Admissibility Game Fixed?: Judicial Gatekeeping of Fire and Arson Evidence

Anecdotal evidence claims that in criminal cases, trial judges admit the prosecution's expert witnesses more readily than the defendants', and in civil cases the reverse is true; judges exclude plaintiffs' experts more often than civil defendants' experts. This occurs despite the fact that, with few exceptions, the same rules of admissibility apply to all parties and, in most jurisdictions, across criminal and civil cases. This article empirically tests this differential by reviewing judicial decisions to admit or exclude evidence holding the type of expert testimony constant, fire and arson evidence, across criminal and civil cases in the United States. The study examines the admissibility of fire and arson investigation experts in criminal and civil cases across all legal parties in fifty‐seven federal and state opinions in the United States. The findings offer empirical support of a bias in criminal cases and in civil cases which present expert witnesses at trial, and is less pronounced, but still evident, on appeal. Specifically, the role of the party that offers the evidence has a profound effect on whether arson evidence is admitted, even when factors around the judge's political affiliation, attorney experience, expert qualifications, and rules of evidence are taken into account.     

Compensation and Compliance: Sources of Public Acceptance of the U.K. Supreme Court's Brexit Decision

The perception that a high court's decision is binding and final is a crucial prerequisite for its ability to settle political conflicts. Under what conditions are citizens more likely to accept controversial judicial rulings? Mass acceptance is determined, in part, by how rulings are framed during public debate. This paper takes a broad view of the strategies and actors that influence the discursive environment surrounding judgments, calling attention to hitherto unexamined determinants of mass acceptance. We theorize that third parties can boost acceptance by pledging compliance, and that courts can moderate opposition by compensating losers. We also look at how populist attacks on judiciaries, common in contemporary democracies, affect acceptance. We test these propositions using a survey experiment conducted in the aftermath of the UK Supreme Court's Brexit decision, the most salient judgment handed down by this court to date. The paper moves the literature on courts and public opinion beyond the United States, and presents evidence backing largely untested assumptions at the heart of models of judicial behavior regarding the benefits of crafting rulings with an eye on the preferences of key audiences.     

The Application of Flow Cytometry as a Rapid and Sensitive Screening Method to Detect Contamination of Vitreous Humor Samples and Avoid Miscalculation of the Postmortem Interval

Research into maximizing the speed, precision, and reliability of estimating the postmortem interval (PMI) has been a recurring object of investigation and methodologies based on the vitreous humor (VH) have provided good results. However, contamination from causes not readily apparent, such as blood, can occur, and thus lead not only to an erroneous estimation of PMI, but also interfere with the correct identification of other substances in the VH. We have developed a flow cytometry method which quantifies blood contamination and is able to detect erythrocytes in 1:750,000 dilution of contaminated VH which affects the results of hypoxanthine. It is an improvement on the previous more complex mass spectrometry method, being faster, more sensitive, and readily available. As such, it could be proposed for the rapid screening of appropriate samples by detecting and eliminating blood contaminated samples from PMI estimation.     

技术冲击、非技术冲击与中国劳动就业的实证分析

运用结构向量自回归(SVAR)方法,将技术冲击和非技术冲击对中国劳动就业的动态效应进行实证分析,得出的主要结论有:劳动就业对正向技术冲击的反应为先立即下降,随后持续上升并回到初始状态,而对正向非技术冲击的反应呈现出在一定时期内先升后降的驼峰形特征,且具有短期效应;生产率水平对技术冲击的反应在一定时期内表现出持续上升的驼峰特征,且具有长期效应,而对正向非技术冲击的反应为先立即上升,后持续下降回到原状态,且具有短期效应;劳动就业波动的根源是由技术冲击和非技术冲击共同引起的,两者都起到一定作用.这些结论对我国当前调整宏观经济政策,以促进劳动就业具有重要的启示.
