Is the length of the sternum reliable for estimating adult stature? A pilot study using fresh sterna and a test of two methods using dry sterna

Stature estimation is one of the four attributes of the biological profile obtained from human skeletal remains. The length of the long bones has been consistently used to estimate stature from regression equations, but these may be useless when dealing with fresh or decomposed mutilated remains. Until recently, there was no consistent assessment of the reliability of measurements of the sternum for stature estimation. The purpose of this paper is to test previously developed regression formulae for stature based on measurements of the dry sternum and to assess the reliability of measurements of the fresh sternum in estimating stature. The formulae developed by Menezes et al. and Singh et al. were applied to a sample of 5 known stature skeletons from the identified human skeletal collection curated at the National Museum of Natural History, in Lisbon, Portugal. Testing of these formulae showed that estimated stature confidence intervals do not allow discrimination between individuals with similar stature. The length of the fresh sternum was measured on a sample of 45 male individuals autopsied at the National Institute of Legal Medicine - North Delegation (Porto, Portugal). Cadaver length was regressed on sternum length and a simple linear regression formula was obtained. The regression model provided a 95% confidence interval of 13.32 cm and a correlation coefficient of only 0.329. Compared to other studies, regression formulae based on the length of the sternum provided considerably larger standard errors than that based on long bone lengths. These results suggest that the length of the sternum has limited forensic value and relatively low reliability in estimating stature from mutilated human skeletal remains, either skeletonized or fresh.     

Risk for Partner Victimization and Marital Dissatisfaction Among Chronically Depressed Patients

The link between marital dysfunction and depressive symptoms has been well established, but the link between partner violence and depressive symptoms is less clear. Further, little is known about partner violence and marital satisfaction in chronically depressed patients. In this multi-site treatment sample of chronically depressed patients (N = 316), approximately 17% of men and 12% of women reported experiencing physical victimization from their partner in the past year. However, physical victimization was not associated with the severity of depression for men or women. Cross-sectional path analyses indicated that depressive symptoms predicted marital dissatisfaction, which in turn, predicted psychological victimization. Further, psychological victimization predicted physical victimization. With chronically depressed individuals, interventions that address both depression and marital dissatisfaction may prevent psychological and physical victimization.     

Parental efficacy, self-control, and delinquency: A test of a general theory of crime on a nationally representative sample of youth

Criminologists have recently begun examining Gottfredson and Hirschi's (1990) proposition that parenting is the primary influence on children's levels of self-control. The few existing studies on the subject, however, have typically been based on small, nonrandom samples. The current study examines the relationships between parental efficacy, self-control, and delinquent behavior using data from a nationally representative sample of adolescents (the National Longitudinal Study of Adolescent Health). The results indicate that although parental efficacy is an important precursor to self-control, contrary to Gottfredson and Hirschi's proposition, self-control does not completely mediate the relationship between parental efficacy and delinquency. The implications for future research and theoretical development are discussed.     

A New Robust Epigenetic Model for Forensic Age Prediction

Forensic DNA phenotyping refers to an emerging field of forensic sciences aimed at the prediction of externally visible characteristics of unknown sample donors directly from biological materials. The aging process significantly affects most of the above characteristics making the development of a reliable method of age prediction very important. Today, the so-called “epigenetic clocks” represent the most accurate models for age prediction. Since they are technically not achievable in a typical forensic laboratory, forensic DNA technology has triggered efforts toward the simplification of these models. The present study aimed to build an epigenetic clock using a set of methylation markers of five different genes in a sample of the Italian population of different ages covering the whole span of adult life. In a sample of 330 subjects, 42 selected markers were analyzed with a machine learning approach for building a prediction model for age prediction. A ridge linear regression model including eight of the proposed markers was identified as the best performing model across a plethora of candidates. This model was tested on an independent sample of 83 subjects providing a median error of 4.5 years. In the present study, an epigenetic model for age prediction was validated in a sample of the Italian population. However, its applicability to advanced ages still represents the main limitation in forensic caseworks.     

Is Greater Fishery Access Better for the Poor? Explaining De-Territorialisation of the Tonle Sap,Cambodia

Abstract

The general tendency for states in South East Asia is to claim exclusive rights over natural resources at the cost of impoverishing the people who depend on them for subsistence. However, contrary to what one might expect, the government of Cambodia initiated unconventional intervention: it cancelled the fishing lots system, the de facto property rights that had granted exclusive access to certain aquatic resources to licence holders. These interventions, focused on Cambodia’s largest lake, question the rationale behind such state measures to forfeit control. This paper demonstrates that political interests such as garnering election votes and circumventing certain bureaucratic agencies explain this radical shift in policy. Opening up previously exclusive lot areas to the communities won immediate support from the poor fishermen. However, now that the lake is under a more diverse, if obscure, system of governance managed by multiple agencies, the environmental and social consequences of the policy shift deserve a fuller examination.

The Determinants of Civic and Ethnic Nationalisms in Kazakhstan: Evidence from the Grass-Roots Level

This article investigates the determinants of ethnic and civic nationalism in post-Soviet Kazakhstan. Using data from an original nation-wide survey (N = 1600), the regression analysis is applied to evaluate the influence of trust and perceptions of discrimination as well as sociodemographic factors on people's support of civic and ethnic nationalism(s) in Kazakhstan. The results show that trust in political institutions, perceived discrimination, and the knowledge of the Kazakh language have an impact on both types of nationalism. In addition, intragroup (ethnic) trust and income determine civic–nationalist attachments, while rural residence, Kazakh ethnicity, income, and other ethnic minorities influence ethnonationalism in Kazakhstan.     

Family Unification Program: Housing Services for Homeless Child Welfare–Involved Families

The Family Unification Program—a U.S. Department of Housing and Urban Development initiative to facilitate interagency collaboration between the child welfare and public housing service systems—aims to stabilize families at risk for parent–child separation by addressing housing needs. Findings from a randomized controlled trial suggest that families referred to the program experienced lower risk for homelessness and out-of-home placement compared with child welfare services as usual. The findings suggest that housing services offer an effective alternative to foster care.
