Using the acetabulum to estimate age at death of adult males

The acetabular region is often present and adequately preserved in adult human skeletal remains. Close morphological examination of the 242 left male os coxae from the identified collection of Coimbra (Portugal) has enabled the recognition of seven variables that can be used to estimate age at death. This paper describes these variables and argues their appropriateness by analyzing the correlation between these criteria and the age, the intra- and interobserver consistence, and the accuracy in age prediction using Bayesian inference to estimate age of identified specimens. Results show significant close correlation between the acetabular criteria and age, nonsignificant differences in intra- and interobserver test, and 89% accuracy in Bayes prediction. Obtained estimated age of the specimens had similar accuracy in all ages. These results indicate that these seven variables, based on the acetabular area, are potentially useful to estimate age at death for adult specimens.     

The death of machothink: Feminist research and the transformation of peace studies

When the life of every creature on this planet is in danger, as it is today, we all have a vested interest in peace research. But peace research tends to be male-biased and does not take into account the experiences and interests of women. Because it is skewed, it is weakened. Feminist research offers a badly needed corrective, and a transformative vision. Data on violence against women, on the links between violence against women and male violence in general, on the nature and experience of power and powerlessness, on mothering, and moral development, have significant implications for peace research. A feminist peace researvh would reground discussions of war and violence in the lived experiences of women, men and children. It would speak about and to all of us.     

Can education policy be health policy? Implications of research on the social determinants of health

Research on the social determinants of health has demonstrated robust correlations between several social factors, health status, and life expectancy. Some of these factors could be modified through policy intervention. National-level public policies explicitly based on population health research are in various stages of development in many Western countries, but in spite of evident need, seemingly not at all in the United States. Because research shows such a strong association between education and good health, we offer evidence to show that at least two pressing problems in American society, namely the uneven distribution of educational attainment and health disparities linked to socioeconomic position, may be ameliorated through policy initiatives that link quality early childhood care, child development programs, and parental training in a seamless continuum with strengthened K-12 education.     

The effect of soil type on adipocere formation

Adipocere refers to a postmortem product which forms from body fat in the later stages of decomposition. Factors present in the surrounding decomposition environment will influence adipocere formation and may accelerate or retard the process of conversion. One such factor important in burial environments is the type of grave soil in which the burial has taken place. This study was conducted to investigate the influence of various soil types on the formation of adipocere in grave soils. X-ray diffraction and particle size analysis were used to characterise the soils which were essentially chosen on the basis of grain size. Infrared spectroscopy, inductively coupled plasma-mass spectrometry, and gas chromatography-mass spectrometry were used to investigate the lipid profile and chemical composition of adipocere developed from decomposing tissue. The results suggest that adipocere is able to form in various soil types and that particular soil environments may accelerate its formation.
