Estimation of age at death from the pubic symphysis and the auricular surface of the ilium using a smoothing procedure

We discuss here the estimation of age at death from two indicators (pubic symphysis and the sacro-pelvic surface of the ilium) based on four different osteological series from Portugal, Great-Britain, South Africa or USA (European origin). These samples and the scoring system of the two indicators were used by Schmitt et al. (2002), applying the methodology proposed by Lucy et al. (1996). In the present work, the same data was processed using a modification of the empirical method proposed by Lucy et al. (2002). The various probability distributions are estimated from training data by using kernel density procedures and Jackknife methodology. Bayes's theorem is then used to produce the posterior distribution from which point and interval estimates may be made. This statistical approach reduces the bias of the estimates to less than 70% of what was obtained by the initial method. This reduction going up to 52% if knowledge of sex of the individual is available, and produces an age for all the individuals that improves age at death assessment.     

Identification of a tooth-like foreign body in Swine sausage

A tooth-like foreign body (FB) was found inside a sausage bread. Analysis aimed to investigate whether the FB was a tooth and its origin. The FB was measured, weighed, photographed, and radiographed. Macroscopic findings were suggestive of an anterior tooth. Histological slides of undecalcified cross-sections of the FB and samples of human and swine teeth were prepared. Histological features of the FB (in light microscopy, 125× magnification) were discrepant from human tissues. Compared histological analysis displayed majority of features consistent with a hypsodont swine tooth, probably a canine. Cellularized cementum in crown region, adjacent to the enamel, and shape of the cementocytes were the main criteria excluding the possibility of human origin of the FB. Scanning electronic microscopy and energy-dispersive spectroscopy were not performed because of fewer features to be analyzed and FB size. It was concluded that the FB may have been incorporated during meat grinding of the sausage.     

Legal Culture and State Building: Liberal Constitutionalism and <Emphasis Type="Italic">Droit Administratif</Emphasis> in early Twentieth Century Argentina

This paper deals with the ways in which jurists and law professors applied transnational systems of public law, in particular US constitutionalism and French droit administratif, in their approaches to the state building process in late nineteenth century Argentina. In covering these movements of adaptation of a nascent legal culture to changing ideological and political circumstances, this article attempts to illuminate the strong links between the process of institutionalization of certain academic disciplines or forms of social knowledge, and modern state building in Latin America.     

Making Sure Neuropsychological Data Are Meaningful: Use of Performance Validity Testing in Medicolegal and Clinical Contexts

Performance validity testing (PVT) is a standard of practice in situations where there are prominent secondary gain issues; however, it is suggested that their use may benefit neuropsychological evaluations in clinical contexts, as engagement in neuropsychological evaluations can affect the validity of testing and can occur for a variety of reasons outside of secondary gain issues. Several methods of embedded index development, as well as methods to combine them are discussed, including issues related to use of multiple indices. The potential limitations to administration of multiple indices are also explored. It is suggested that neuropsychological evaluations can benefit from PVT in regular clinical practice to assist with reaching firmer diagnostic conclusions by assuring test result validity.     

A Tale of Should Be but Is Not: the Political and Economic Drivers of Limited Chinese Investments in Colombia

Chinese outward foreign direct investment (FDI) has been one of the economic tools China has used to engage South America. Although Colombia has been attracting inward FDI in quantities similar to other key regional states, its macroeconomic and sectoral features and investment attraction policies positively correlate with many of the factors known to attract Chinese outward FDI (OFDI), and both the Colombia and Chinese governments are committed to increasing Chinese OFDI (COFDI) flows to Colombia, COFDI volumes to the Andean nation have yet to live up to expectations. This puzzling case highlights the need for a better understanding of the political-economic factors that drive COFDI. My case study show that Colombia’s political and economic traits have been hindering COFDI. Regarding the former, Colombia’s local politics regarding extractive activities and bidding on infrastructure projects and its close relations with the United States function to create an adverse environment for increased COFDI. With respect to the latter, the international economic environment, especially regarding commodities’ prices, has impaired Chinese investment in Colombia. Overall, Colombia’s case underscores the delicate interplay of international, national, and subnational factors on COFDI flows.

     

Neo‐patrimonialism and Corruption: Evidence from 8,436 Firms in 17 Countries in Sub‐Saharan Africa

This article introduces four innovations to the literature on administrative corruption. First, it employs a neo‐patrimonialism framework by addressing measurement, identification, and endogeneity issues that beset the literature. Second, unlike cross‐country studies, it uses firms as the unit of analysis. Third, unlike the conventional literature, the article uses large‐n (n = 8,436) panel survey data of key informants in 17 countries in sub‐Saharan Africa. Finally, unlike the conventional literature, the article focuses on a particular type of corruption: the supply and demand for bribery. The authors find that the uncertainty associated with neo‐patrimonialism has a strong, positive, and significant effect on the propensity of civil servants to demand bribes in exchange for services and for firms to supply bribes in exchange for winning government contracts. The results are robust to controls on the characteristics of firms and their regulatory environments. The article concludes with implications for research and practice.     

Age estimation by measurements of developing teeth: accuracy of Cameriere's method on a Brazilian sample

Developing teeth are commonly the criteria used for age estimation in children and young adults. The method developed by Cameriere et al. (Int J Legal Med 2006;120:49-52) is based on measures of teeth with open apex, and application of a formula, to estimate chronological age of children. The present study evaluated a sample of panoramic radiographs from Brazilian children from 5 to 15 years of age, to evaluate the accuracy of the method proposed by Cameriere et al. The results has proven the system reliable for age estimation, with a median residual error of -0.014 years between chronological and estimated ages (p = 0.603). There was a slight tendency to overestimate the ages of 5-10 years and underestimate the ages of 11-15 years.
