The Utility of the Samworth and Gowland Age‐at‐Death “Look‐up” Tables in Forensic Anthropology*

Abstract: Accurate age‐at‐death estimates are crucial to forensic anthropologists when onstructing biological profiles aimed at narrowing a missing‐persons list and to allow for timely and efficient identification of an unknown victim. The present contribution evaluates the utility of three new age‐at‐death estimation techniques recently proposed by Samworth and Gowland (2007). Results indicate that, in the samples under study, the Samworth and Gowland estimates from the pubic symphysis and auricular surface perform similar to alternate phase methods. The combined method does not appear to further enhance either the precision or the accuracy of the single pubic symphysis age‐at‐death estimate. In conclusion, these new methods seem to be more robust to distribution deviations than originally proposed by Samworth and Gowland (2007). They are therefore suitable for immediate and reliable forensic usage in the United States and worthy of further research for their use in North American forensic contexts.     

Characteristics and Prediction of Cranial Crush Injuries in Children*†

Abstract: This study documents four clinical cases of fatal crush injuries to children between 1.5 and 6 years of age with correlations between modeled stress and clinically observed fracture patterns. The clinical case fractures were concentrated in the basicranium, bridged the impact sites, and traversed the middle cranial fossa in the area of the spheno‐occipital synchondrosis. The crushing forces from these cases were recreated on a simplified finite element model of a cranium by applying bilateral pressures to corresponding regions. Numerous trials were run to develop a representative pattern of principal stress directions. In all cases, the highest tensile stresses were located on the basicranium and corresponded to the observed fracture path(s). These results suggest that prefailure stress field diagrams may predict fracture propagation paths, although these will not be exact. Also, these analyses indicate that quasi‐static bilateral loading of the cranium may lead to predictable fracture of the basicranium.     

TOWARD THE DIFFERENTIATION OF HIGH‐CONFLICT FAMILIES: AN ANALYSIS OF SOCIAL SCIENCE RESEARCH AND CANADIAN CASE LAW

Social science research and the courts have begun to recognize the special challenges posed by “high‐conflict” separations for children and the justice system. The use of “high conflict” terminology by social science researchers and the courts has increased dramatically over the past decade. This is an important development, but the term is often used vaguely and to characterize very different types of cases. An analysis of Canadian case law reveals that some judges are starting to differentiate between various degrees and types of high conflict. Often this judicial differentiation is implicit and occurs without full articulation of the factors that are taken into account in applying different remedies. There is a need for the development of more refined, explicit analytical concepts for the identification and differentiation of various types of high conflict cases. Empirically driven social science research can assist mental health professionals, lawyers and the courts in better understanding these cases and providing the most appropriate interventions. As a tentative scheme for differentiating cases, we propose distinguishing between high conflict cases where there is: (1) poor communication; (2) domestic violence; and (3) alienation. Further, there must be a differentiation between cases where one parent is a primary instigator for the conflict or abuse, and those where both parents bear significant responsibility.     

Finance-investment-growth nexus in South Africa: an ARDL-bounds testing procedure

In this paper we examine the dynamic causal relationship between financial development, investment and economic growth in South Africa—using the newly developed ARDL-Bounds testing procedure. Unlike the majority of the previous studies, we incorporate investment in the bivariate model between financial development and economic growth—thereby creating a simple trivariate causality model. In addition, we use three proxies of financial development, namely M2/GDP, the ratio of private sector credit to GDP and the ratio of liquid liabilities to GDP in order to test the robustness of the results. Our results show that, on the whole, economic growth has a formidable influence on the financial sector development. The study also finds that there is a distinct unidirectional causal flow from economic growth to investment. Moreover, the study also finds that investment, which results from growth, Granger-causes financial development. The study, therefore, recommends that South Africa should intensify its pro-growth policies in order to bolster investment and financial development.     

Identity and its verification

The European Commission's eJustice Strategy seems to contemplate that all lawyers will be issued with an ‘identity card’ card, perhaps intended to include a key for making digital signatures. The Council of Bars and Law Societies of Europe (CCBE) is proposing to introduce such a card. The purpose of this article is to clarify what ‘identity’ is and what is involved in verifying it, and to offer some general observations about identity cards. Although written with the eJustice proposals in mind, nevertheless the purpose of this article is to address the topic in its widest sense, which means it affects identity and its verification, whatever the circumstances.     

Testing a promising homicide reduction strategy: re-assessing the impact of the Indianapolis “pulling levers” intervention

Since the publication of analyses suggesting the significant impact on youth homicide of the Boston “pulling levers” intervention, a series of studies of similar strategies have indicated promise in reducing homicide and gun assaults. One of these studies was an assessment of a pulling levers strategy in Indianapolis, where trend analyses indicated a significant reduction in homicide following the intervention, while six other similar Midwestern cities did not experience a significant decline in homicide. We re-assess the results of the Indianapolis study by disaggregating the offenses into gang- and non-gang homicides. Given that the pulling levers program focused on influencing gangs and networks of chronic offenders, the impact of the intervention should be more apparent for gang homicides than for non-gang homicides. Alternatively, should the impact be similar for non-gang homicides, then it is more likely that the downward trend would be caused by unmeasured external forces. Coefficient-difference tests relying on estimates obtained from autoregressive integrated moving average (ARIMA) time–series models indicate that gang homicides declined significantly more than did non-gang homicides following the Indianapolis intervention. These findings suggest ‘something happened’ to gang homicides that did not happen to non-gang homicides, which adds further support that the pulling levers initiative was the driving force behind the overall reduction in homicide in Indianapolis.

Scientific integrity in the forensic sciences: Consumerism,conflicts of interest,and transparency

The goal of this paper is to discuss scientific integrity, consumerism, conflicts of interest, and transparency within the context of forensic science. Forensic scientists play crucial roles within the legal system and are constantly under various pressures when performing analytical work, generating reports based on their analyses, or testifying to the content of these reports. Maintaining the scientific integrity of these actions is paramount to supporting a functional legal system and the practice of good science. Our goal is to discuss the importance of scientific integrity as well as the factors it may compromise, so that forensic practitioners may be better equipped to recognize and avoid conflicts of interest when they arise. In this discussion we define terms, concepts, and professional relationships as well as present three case studies to contextualize these ideas.     

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 end of organised crime in the European Union

So much has been written—and vigorously contested—about ‘organised crime’ (OC) that the impending fall of this familiar icon may come as a shock, both to its detractors and to those who take it for granted. Yet that moment may be upon us, for reasons that this paper will explore, as the European Union shifts the vocabulary within which policies on police cooperation are articulated. A pivot of this change is the EU Council Decision on Europol, first debated by the Council in late 2006 and anticipated as applying from 2010 onwards. This will shift the scope of Europol’s work from ‘organised crime’ (attributing qualities to criminality) to ‘serious crime’ (concern with impacts and harms falling on individual and collective victims); will transfer financing of Europol to the Community budget; and so will initiate parliamentary scrutiny. These issues in security governance are explored from ‘northern’, ‘southern’ and ‘eastern’ European perspectives and in the contexts of ongoing enlargement and democratisation of the EU.

Efficacy,Emotions and the Habit of Participation

Political behavior is triggered by the presence of a variety of material and cognitive resources, including political efficacy. The dominant view conceptualizes efficacy as capital, used to overcome obstacles to participation. Our theory suggests that unlike other resources, efficacy aids in the development of habitual participation by activating a particular negative emotion, anger. Using the 1990–1992 NES Panel, we find that internal efficacy boosts participation in part by facilitating anger, but not fear, in response to policy threats. This partial mediating effect operates primarily among younger citizens who are in the process of developing the habit of participation. External efficacy, because it is not self-referential, is not causally linked to participation via emotions. Finally, internal efficacy is enhanced by successful participation in politics, closing a feedback loop that helps explain participatory habits.
