A Proposed Scheme for Classifying Pediatric Rib Head Fractures Using Case Examples

Pediatric rib head fractures are typically described as “posterior” or “costovertebral,” terms lacking specificity. To resolve this issue, a scheme was developed to describe the location of rib head fractures observed in a pediatric forensic population. The scheme uses three anatomical landmarks, terminus (tip), tubercle, and costovertebral articular surface to divide the rib head into two subregions, costovertebral and costotransverse. Examples of five cases of infants with rib head fractures are presented using this scheme. Forty‐eight rib head fractures were observed in these infants with the following frequencies: 56% (three infants) at the terminus; 21% (three infants) in the costovertebral subregion; 21% (one infant) at the costovertebral articular facet; and 2% (one infant) in the costotransverse subregion. Due to the small number of cases assessed, statistical analyses could not be performed; however, the data demonstrate the variation in distribution of pediatric rib head fractures.     

Microscopic Saw Mark Analysis: An Empirical Approach

Microscopic saw mark analysis is a well published and generally accepted qualitative analytical method. However, little research has focused on identifying and mitigating potential sources of error associated with the method. The presented study proposes the use of classification trees and random forest classifiers as an optimal, statistically sound approach to mitigate the potential for error of variability and outcome error in microscopic saw mark analysis. The statistical model was applied to 58 experimental saw marks created with four types of saws. The saw marks were made in fresh human femurs obtained through anatomical gift and were analyzed using a Keyence digital microscope. The statistical approach weighed the variables based on discriminatory value and produced decision trees with an associated outcome error rate of 8.62–17.82%.     

The Politics of Obstruction: Republican Holds in the U.S. Senate

A defining feature of the modern US Senate is obstruction. Almost all pieces of legislation considered in the Senate are affected either directly or indirectly by obstruction. Obstruction takes many forms in the modern Senate, but one of the most prevalent, yet least studied, is the hold. Using a newly created dataset on Republican Senate holds, we cast light on this important practice. Our results suggest that a variety of factors including timing, party status, and a senator's voting record are related to both the prevalence of holds and the success of legislation subject to holds in the Senate.     

Great Plains harvest: evolution of the US public employment service,transnational labor,and nonimmigrant visas

Government H-2A visa data and employer surveys show that Great Plains custom harvesting operations now rely on the US public employment service (PES) and private labor agencies to hire transnational labor. Wheat harvest labor problems and private labor bureau abuses during the Progressive Era were a driving force in the formation and development of the local, state, and federal PES agencies that are now used to secure foreign workers. The PES addressed harvest labor problems from the late nineteenth century until the 1930s when mechanization and drought sufficiently reduced labor demand. The PES became active in the wheat harvest again during WW II and into the 1950s until mobile custom combining crews eliminated the need for the federal government’s involvement. Beginning in the 1990s, domestic labor scarcity caused custom harvesting employers to hire foreign labor through the H-2A and J-1 visa programs. The PES is part and parcel of the H-2A visa program, but unlike most agricultural employers that use H-2A labor, foreign workers in custom harvesting are from South Africa, New Zealand, Australia, and numerous European and other countries rather than Latin America. Transnational custom harvesting employees that use H-2A visas occupy a niche within the program and thereby maintain Great Plains harvesting’s unique place in the labor market. This article traces the concurrent evolution of Great Plains harvesting and the PES from the end of the nineteenth century to the 1950s and examines the role of the PES and private labor agencies in today’s global labor market.     

The true extent of global poverty and hunger: questioning the good news narrative of the Millennium Development Goals

The final report on the Millennium Development Goals (MDGs) concludes that the project has been ‘the most successful anti-poverty movement in history’. Two key claims underpin this narrative: that global poverty has been cut in half, and global hunger nearly in half, since 1990. This good-news narrative has been touted by the United Nations and has been widely repeated by the media. But closer inspection reveals that the UN’s claims about poverty and hunger are misleading, and even intentionally inaccurate. The MDGs have used targeted statistical manipulation to make it seem as though the poverty and hunger trends have been improving when in fact they have worsened. In addition, the MDGs use definitions of poverty and hunger that dramatically underestimate the scale likely of these problems. In reality, around four billion people remain in poverty today, and around two billion remain hungry – more than ever before in history, and between two and four times what the UN would have us believe. The implications of this reality are profound. Worsening poverty and hunger trends indicate that our present model of development is not working and needs to be fundamentally rethought.     

Rethinking the Roots of Terrorism: Beyond Orthodox Terrorism Theory—A Critical Research Agenda∗

The orthodox understanding of terrorism does not seem to provide adequate means for explaining the root causes of terrorism. This study is an attempt to critically rethink the roots of terrorism by relocating the study of terrorism into a conceptual space in which it can gain access to the tools provided by conflict studies. As a result this work addresses a gap in the field of terrorism studies and provides an explanation and clarification of the existence of orthodox terrorism discourse and the creation of an alternative theoretical framework for rethinking the roots of terrorism.     

The detection of simulated amnesia

Claims of amnesia are frequently raised in criminal and civil cases. There is a consensus in the legal community that amnesia is easily faked and practically impossible to disprove, and that many who claim to be amnesic are malingering. The present studies compared, on a variety of memory tasks, subjects instructed to simulate amnesia with subjects who had memory impairments due to brain damage. The simulators displayed patterns of performance different from those of memory-impaired subjects. These results suggest that lay-people have inaccurate beliefs about the cognitive features of amnesia, and do not distinguish among etiologically distinct amnestic disorders. Tasks that exploit lay-people's inaccurate beliefs about amnesia appear promising for the detection of malingering.
