Estimation of Living Stature from Selected Anthropometric (Soft Tissue) Measurements: Applications for Forensic Anthropology

Abstract:  Estimation of living stature has obvious utility in the identification process. Typically, anthropologists estimate stature from the measurement of long bone length. This type of analysis is traditionally conducted on skeletonized or badly decomposed remains, so collection of the necessary bone measurements is relatively simple. As the role of anthropologists expands into medical examiner offices and mass fatality incidents, the analysis of fleshed bodies and body parts is a more common scenario. For stature estimation in these types of cases (e.g., analysis of body portions recovered from an aircraft crash site or from intentional dismemberment), the presence of soft tissue on the human remains would usually necessitate dissection to expose skeletal elements to derive metric data for stature estimation. In order to circumvent this step, this paper provides various formulae that allow for standard anthropometric (i.e., soft tissue) measurements to be used in place of skeletal measurements. Data were compiled from several anthropometric studies (National Health and Nutrition Examination Survey [NHANES] and U.S. Army Anthropometric Survey [ANSUR]) and numerous regression models are presented. Results are compared between skeletal measurements and the anthropometric measurements from each study. It was found that the ANSUR models are similar to the skeletal models, while the NHANES models exhibit weaker correlation coefficients and higher standard errors. Overall, this study finds that stature estimates derived from anthropometric data provide good results and remove the necessity for dissection when working with fleshed body portions.     

THE EFFECT OF RECENT TAX CHANGES ON TAXABLE INCOME: CORRECTION AND UPDATE

This article is a Commentary on Bradley T. Heim ( 2009 ), The effect of recent tax changes on taxable income: Evidence from a new panel of tax returns,” Journal of Policy Analysis and Management, 28, 147–163. doi: 10.1002/pam.20406 . This note provides corrected estimates of the elasticity of taxable income to the net of tax share using a panel of tax returns that follows a random sample of taxpayers from 1999 to 2005, spanning the EGTRRA 2001 and JGTRRA 2003 tax changes. Two errors were corrected: the specification of income splines, and the subtraction of capital gains income from the dependent variable. Though the original results are largely robust to the first change, they are not robust to the second. The corrected estimates suggest that the elasticity of taxable income to the current year's net of tax share is small and statistically insignificantly different from zero.     

Political, Religious and Cultural Identities: The Undercurrents of Scottish Football

Despite recognition that religion plays an important role in Scottish and that Scotland has long been different from England in matters involving religion, there remains a dearth of relevant research on this subject. For example, only in recent years, with the works of Mitchell (1992) and Curtice and Seawright (1995), has there been a qualified look at least at one aspect of this relationship, the association between religion and politics. This paper will bring both of these subjects together by considering the religious and political undercurrents that for many people have come to characterise Scottish football. A characterisation that is particularly evident in the case of the two major clubs in Scotland: Glasgow Rangers and Celtic.     

WORKFARE IN THE 1980s: SUCCESSES AND LIMITS

Between 1981 and 1987 twenty-eight states experimented with workfare programs. By requiring mandatory community service from welfare recipients, the states hoped to reduce welfare caseloads as well as increase community service. Based in part on those program experiences, Congress included the first national workfare requirement in the 1988 welfare reform package (the Family Support Act). This study is the first to attempt to evaluate the implementation and impact of workfare on a national basis. A pooled, cross-section, longitudinal model is used to estimate the effect of workfare on AFDC caseloads. Despite the low level of state-level implementation, the evidence suggests that workfare may have contributed to welfare caseload reductions in the 1980s.     

Economic costs of Oxford House inpatient treatment and incarceration: a preliminary report

The Oxford House model for substance abuse recovery has potential economic advantages associated with the low cost of opening up and maintaining the settings. In the present study, annual program costs per person were estimated for Oxford House based on federal loan information and data collected from Oxford House Inc. In addition, annual treatment and incarceration costs were approximated based on participant data prior to Oxford House residence in conjunction with normative costs for these settings. Societal costs associated with the Oxford House program were relatively low, whereas estimated costs associated with inpatient and incarceration history were high. The implications of these findings are discussed.     

The influence of policy on the differential expansion of male and female self-run recovery settings

The present study used archival data to examine the differential growth among self-governed substance abuse recovery homes for men (N = 443) and women (N = 125). The number of these homes increased dramatically across the U.S. from 1988-1999 when state loan funds were made available to states and technical assistance was utilized by organizations developing the houses. State loan programs and the utilization of technical assistance, however, had the strongest impact on the expansion of women's houses compared to men's houses. The implications of these findings in relation to the scarcity of recovery options for women are discussed.     

Evaluating the forensic informativeness of mtDNA haplogroup H sub-typing on a Eurasian scale

The impact of phylogeographic information on mtDNA forensics has been limited to the quality control of published sequences and databases. In this work we use the information already available on Eurasian mtDNA phylogeography to guide the choice of coding-region SNPs for haplogroup H. This sub-typing is particularly important in forensics since, even when sequencing both HVRI and HVRII, the discriminating power is low in some Eurasian populations. We show that a small set (eight) of coding-region SNPs resolves a substantial proportion of the identical haplotypes, as defined by control-region variation alone. Moreover, this SNP set, while substantially increasing the discriminating efficiency in most Eurasian populations by roughly equal amounts, discloses population-specific profiles.     

Sleep apnea as a possible factor contributing to aggression in sex offenders

Sleep disorders, such as obstructive sleep apnea (OSA), are often unrecognized and undertreated. A disruption in normal sleep may be associated with increased irritability and aggression. To elucidate further the impact of OSA on hostility of forensic patients, we performed a retrospective chart review of 10 consecutive outpatient sex offenders who were diagnosed with OSA and treated with continuous positive airway pressure (CPAP). The Buss-Perry Aggression Questionnaire was compared pre- and posttreatment. Following treatment, the total Buss-Perry score was significantly lower, with lower scores on the anger, physical aggression, hostility, and verbal aggression subscales. These results suggest that in sex offenders suffering from OSA, aggression and hostility may be significantly reduced through CPAP treatment. Further investigation is required to investigate if reducing aggression and hostility in this manner impacts recidivism and overall functioning.
