Outline Shape Analysis on the Trochlear Constriction and Olecranon Fossa of the Humerus: Insights for Sex Estimation and a New Computational Tool,

Sex estimation through visual analysis of the distal humerus can contribute to establishing the biological profile of an unidentified skeletal individual. Using statistical shape modeling, the trochlear constriction open curves and olecranon fossa closed outlines of 151 humeri were digitized and analyzed. The shape configurations exhibited strikingly different degrees of sexual dimorphism when evaluated using linear discriminant analysis with leave‐one‐out cross‐validation. The trochlear constriction performed poorly, correctly classifying 63.6% of the individuals. However, the olecranon fossa showed high sexual dimorphism, presenting a 94.0% accuracy. A simpler model using only two principal components was also generated. While the accuracy is slightly inferior (88.1%), it has the advantage of being constrained to bidimensional components that were translated into morphoscopic variables within a simulator interface. This allowed us to implement the method through a web application that does not require users to be trained in landmark digitization or have knowledge of geometric morphometrics.

Piophila megastigmata (Diptera: Piophilidae): first records on human corpses

Piophila megastigmata McAlpine, 1978, for many years only known from South Africa, was recently recorded in Spain. The present work reports for the first time the occurrence of P. megastigmata in human corpses in Portugal. The species was also collected in succession studies conducted with piglet carcasses, where it coexisted with Stearibia nigriceps (Meigen, 1826), showing similar periods of presence in the carcass. However, P. megastigmata was more abundant than S. nigriceps in autumn, with the opposite in summer. During winter neither species was able to colonize carrion and in spring, only S. nigriceps. This first record of P. megastigmata in human corpses confirms it as a potentially useful forensic species in Europe. The species, well established in the Iberian Peninsula, probably has a wider distribution but has been previously overlooked and possibly confused with Piophila casei (Linnaeus, 1758) in many studies.

The “microwave oven” practice in Brazil

This article presents a forensic case of an unusual illegal cremation of a person using a process colloquially known as the “microwave oven” practice in Brazil. The microwave process involves two actions: placing the victim in a tire stack and then setting the structure on fire using flammable substances to accelerate the progression. A similar practice, identified as “necklacing”, has also been reported in other countries such as South Africa. This report presents a case of microwave oven cremation of a body found in a rural area of Minas Gerais, Brazil. The forensic work helped determine the biological profile and identity of the victim using radiological comparisons. Although the microwave oven cremation practice is rare, it can impose challenges for investigators. Therefore, fully understanding this practice can be helpful to the academic and forensic communities.     

Inequality and Growth: Uncovering the Main Conclusions from the Empirics

Abstract

This paper is a critical survey of the empirical literature on the effects of inequality on economic growth. We conclude that it is most likely that the disparities found in the results are due to differences in the type of countries and time periods included in the samples, the variable used to measure inequality, the structure of the data, and the estimation techniques. These findings suggest that the mechanisms that link inequality to growth are likely to operate differently in different circumstances, an element that may offer important guidelines for both policy makers and researchers.     

Spatial Distributions of Oxygen Stable Isotope Ratios in Tap Water From Mexico for Region of Origin Predictions of Unidentified Border Crossers

One of the many difficulties associated with identifying undocumented border crossers stems from an inability to narrow down the search area for the region of origin and family members to obtain family reference samples for DNA comparison. While the geography of regions of origins is wide, the biological profiles of the undocumented border crossers often show strong similarities, young and male. The isotopic composition of human bones, teeth, and hair has been demonstrated to be useful biomarkers for tracing locations and movements of individuals and for aiding in the identification of human remains. Data obtained from human remains can be compared to and aligned with various reference sources, such as soils and bedrock, archaeological remains, or cultural data. Here, the spatial deficiency in isotopic reference data for Mexico, specifically for oxygen (δ¹⁸O) isotopes in tap water, is being addressed through the collection and analysis of over 150 water samples and explored with tooth enamel isotopic values from recently identified Mexican nationals. The isoscape was developed using a Spine with Barriers interpolation method and shows sufficient detail to narrow down the regions where specific isotopic values are represented. The individuals were plotted on the developed isoscape using conditional correlations. The methodology was successful in assigning the correct regions of origin for the two individuals, which shows the tremendous potential of the developed isoscape. Nonetheless, there is more research needed to further improve upon this geolocation method, including analysis of multiple isotopes in different tissues, and the development of new isotopic methods.     

Congress and the political expansion of the U.S. districts courts

Expanding the number of U.S. district judgeships is often justifiedas a response to expanding caseloads. Increasing judgeshipsduring unified government, however, allows Congress and thePresident to engage in political (patronage and ideological)control of the federal district courts. This paper examinesempirically the relative importance of caseload pressure andpolitical motives for Congress to expand the number of federaldistrict judgeships. We demonstrate that politics dominatesthe timing of judgeship expansion in the U.S. District Courts.We also show that both politics and caseload affect the actualsize of those timed expansions. In particular, we find thatbefore 1970, Congress seemed to have strong political motivationsfor the size of an expansion. After 1970, Congress became muchmore attentive to caseload considerations.
