Renal artery bullet embolism.

Bullet embolism is a well-recognized phenomenon. While bullet embolism is not common, renal artery bullet embolism appears to be very rare. We report three cases of bullet embolism to a renal artery. Autopsy findings and bullet types are presented. Such cases are of particular interest to both the medical examiner and the clinician. Failure to consider this phenomenon clinically could lead to infarction of a kidney. A consideration of this phenomenon at autopsy could shorten the dissection time required to retrieve the bullet.     

The impact of the commonwealth preference system on the exports of Latin America to the United Kingdom

This paper quantitatively assesses the effect of value chain development projects on market linkages of small-scale farmers of a staple crop and agricultural income. We focus on Nicaraguan bean producers participating in a value chain development project. Using a panel data set, we apply difference-in-differences and instrumental variables estimators to identify causal effects of programme participation. We first quantify the positive direct effect of training on bean sales in terms of quantity and percentage of beans sold in linked markets. Second, we show that intensified commercialisation contributes to total agricultural income, suggesting a positive indirect effect of the intervention. Our results indicate that market linkage of smallholder farmers requires different sets of intervention tools than farm technical assistance.     

Externalities in comparative guise

For those working with social science presumptions, ethical principles can seem to come out of nowhere. This paper wonders whether they operate like the positive externalities Callon wishes to derive from economists. In exploring the question, it is forced to consider different models of internal and external positioning. It does this through taking up two manifestations of the technological economy concerned with information management, following examples drawn from Callon's own work (competitive patenting and ethical deliberations on biotechnology).     

Forecasting the Political Economy of the Inner Solar System

Social structural methods are applied to forecast the political economy of the inner solar system to the 22nd century. One method considers structural indicators, specifically, population, social organization, environment, and technology. Another method examines the Tongan diaspora as an analog of human expansion into space. This future political economy could emerge as a consequence of user strain on a global electrical power grid that develops by 2050. Alternative energy needs could turn to space-based sources. If on-orbit space-based energy infrastructure provides the rationale, capability, and allure to see humans routinely living and working in space, their presence on the Moon and among the near-Earth asteroids can lead to a human diaspora to Mars and its moons. These events will build the multi-planet economy, the multi-world system of societies, and the transnational state. The development of Mars will reach a maturity of settlement from 2130 onward. As these potential events become history, capital would be transformed, and higher-order space logistics in a multi-world system of societies with its multi-planet economy would lay the foundation for a Solar System Federation. This federation constitutes transnational states among off-world human societies that could fill the vacuum of a fading Westphalian nation-state system on Earth.     

A case of factitious pedophilia

Factitious disorder involves feigning, exaggerating, or self-inducing physical and/or psychological ailments with the goal of assuming the "sick" or "patient" role. In turn, the sick role entitles the factitious disorder patient to care, nurturance, and protection; it also exempts one from usual responsibilities. In this paper, we present the first reported case of factitious pedophilia. Although it seems counterintuitive, this middle-aged man has falsely claimed or exaggerated sexual desire for minors ostensibly to remain in a state hospital; indeed, he has remained in the same inpatient facility for more than 20 years as a result of his deceptions. At times, his reports have included disconfirmed claims of bizarre accidents and other physical travails. This case enlarges the literature on factitious psychological disorders and shows that some individuals may falsify paraphilic behaviors, although clearly minimization of these behaviors remains more common.     

Disaggregating Mass Public Shootings: A Comparative Analysis of Disgruntled Employee,School, Ideologically motivated,and Rampage Shooters

This study compares the demographic, background, motivation, and pre‐event and event‐level behaviors across four types of mass public shooters: disgruntled employee, school, ideologically motivated, and rampage offenders. Using a database containing detailed information on 318 mass public shootings that occurred in the United States between 1966 and 2017, we find systematic differences in the characteristics, motivations, target selection, planning, and incident‐level behaviors among these offenders. The results show that ideologically motivated shooters to be the most patient, and methodical, and as a result the most lethal. Conversely, disgruntled employees, who are driven by revenge, tend to have little time to plan and consequently are the least lethal shooters. These, among other differences, underscore the need for prevention strategies and policies to be tailored to specific types of offenders. Furthermore, the results also highlight commonalities across offender type, suggesting that the social and psychological pathways to violence are universal across offenders.
