Quantification of the subpubic angle in South Africans

Due to the high crime rate in South Africa, forensic anthropologists are increasingly approached to aid in the identification of skeletonized remains, with sex and population affinity assignment being some of the most critical tasks they face. For over a century, the pelvis has been known to be one of the most sexually dimorphic bones of the human body and the subpubic angle is one of the most accurate, albeit scarcely quantified, features thereof. Hence, the aim of this study was to quantify the size of the subpubic angle and compare it between male and female South Africans of African (black) and European (white) descent. One hundred and forty five (145) pelves were selected, consisting of 68 white (43 male and 25 female) and 77 black South Africans (44 male and 33 female), from the Raymond A. Dart Collection of Human Skeletons housed at the University of the Witwatersrand, Johannesburg, South Africa. Each of the pelves were articulated and placed into a custom built stand for photographing. Measures of the subpubic angle from these digital images were subjected to numerous statistical analyses. Results indicated that significant differences exist between the sexes, as well as between the two population groups. For black individuals it was found that males generally possessed a subpubic angle of 74.9° or less, with larger values being indicative of the female sex. For white individuals, subpubic angles of 81.4° and less indicated males whilst larger values indicated females, with an average accuracy of 86% for both population groups. These results illustrate the advantages of using the subpubic angle to assist in the estimation of sex and population affinity and also reinforce the need for population specific parameters to be applied.     

Are there population differences in minutiae frequencies? A comparative study of two Argentinian population samples and one Spanish sample

In recent years, both scientific and judicial sources have highlighted the need for more knowledge about minutiae variability, in order to improve their statistical application to fingerprint identification. In line with this trend toward improving our knowledge of this subject, the aim of the present study was to calculate the frequency with which 20 types of minutiae appeared in 2780 fingerprint impressions obtained from 278 individuals from two Argentinian population samples (100 individuals from Ramal and 178 from Puna-Quebrada). The different types of minutiae were located, identified, and quantified visually in two areas on the fingerprint, the inside and outside of a circle, the radius of which cut fifteen ridges perpendicularly, starting from the center cut of the axes defining the sectors. The non-equiprobability found in both population samples for the different minutiae types studied demonstrated that the evidential weight provided by these characteristics is not the same when applied in identification processes, whether used quantitatively (numerical standard) or qualitatively (holistic method). The results obtained for both populations were compared statistically with those published previously for a Spanish population sample, which had been collected using the same methodology. This comparison has enabled us to demonstrate, for the first time, the existence of significant differences between populations in minutiae frequencies, independently from the main pattern type.     

Disobedience and Criticism. The Ethos of Ombudsman's Institution and the "East-European Revolution of Human Rights"

The commissioners of human rights in the Parliament aim at ensuring the protection and formation as well as the development of the culture of human rights with their activities in Hungary and all over the world. What else could be done by the citizens practising their disobedience during the non-violent revolutions in 1989 after Mahatma Gandhi, Martin Luther King and the American Henry David Thoreau? At a first glance, it perhaps seems to be strange to put the following question: what is the connecting link between the role of political law of a public state and the citizens breaking the rules in order to protect the constitutional rights? What will be the result of this comparison? I think, the result is that we can recognize the role of both functions more thoroughly in operating the constitutional state suitably in order to protect the culture of constitutional rights (reactive role) and to develop them (proactive role).     

Constitutional Law in Twenty Years from Now

The principles of constitutional law as those of many other disciplines seem to develop and to be replaced by new paradigms in the light of globalization. The present article using the genre of constitutional futurology attempts to determine whether this change is real or an illusory impression, and to predict the future of constitutional law and of scholarship reflecting on constitutional issues. A mighty forecast emerges from the interplay of opposing forces. While the withering away of the constitutionalist paradigm is unlikely partly because of the lack of a new generation of legal scholars following new patterns of thinking, partly because there is no reason to assume that the prevalent socioeconomic order would cease to exist , the essay maps a number of possible challenges like genetic engineering or personal computers interconnected in the World Wide Web , which constitutionalists shall expect to face in theory and in practice alike.

Note – Walking on Solid Ground: A Replication Study of ‘Housing Health and Happiness’

This note summarises our replication study ‘Housing, Health, and Happiness’, henceforth HHH2009, which constitutes an important paper in the literature of housing and slum upgrading. The original authors conduct a quasi-experimental impact evaluation of ‘Piso Firme’, an intervention that replaced in-house dirt floors with cement in Mexico. We conduct a Pure Replication (PR), a Measurement and Estimation Analysis (MEA), and a Theory of Change Analysis (TCA). In our PR, we did not find any major discrepancy with the original study. In the MEA, we generally find the results to be strongly robust to different types of alternative analysis. Finally, in TCA we explore a dimension that was not reported on the published version of the study and found that households with high initial levels of cement-floor coverage benefitted significantly less from Piso Firme’s intervention. These findings are discussed in greater detail on International Initiative for Impact Evaluation’s (3ie) working paper version.
