Reliability of Craniofacial Superimposition Using Three‐Dimension Skull Model

Craniofacial superimposition is a technique potentially useful for the identification of unidentified human remains if a photo of the missing person is available. We have tested the reliability of the 2D‐3D computer‐aided nonautomatic superimposition techniques. Three‐dimension laser scans of five skulls and ten photographs were overlaid with an imaging software. The resulting superimpositions were evaluated using three methods: craniofacial landmarks, morphological features, and a combination of the two. A 3D model of each skull without its mandible was tested for superimposition; we also evaluated whether separating skulls by sex would increase correct identifications. Results show that the landmark method employing the entire skull is the more reliable one (5/5 correct identifications, 40% false positives [FP]), regardless of sex. However, the persistence of a high percentage of FP in all the methods evaluated indicates that these methods are unreliable for positive identification although the landmark‐only method could be useful for exclusion.     

Legal Typologies and Topologies: The Construction of Indigenous Alterity and Its Spatialization Within the Colombian Constitutional Court

This article examines the different legal articulations between indigenous typologies and topologies, that is, the relationship between someone classified as an indigenous subject, a grantee of minority rights, and the spatial arrangements such as reservations or ancestral territories considered necessary for indigenous “cultural survival.” I analyze how the jurisprudence of the Colombian Constitutional Court manifests and rests on the diverse combinations of these two factors. The typology/topology binary characterizes the manner in which these legal discourses portray indigeneity and culture. This binary also offers insight into a broad range of issues, including the access that indigenous peoples have to minority rights, the use of customary law, and the spatial delimitations that frame indigenous legal jurisdictions. Some of the complexities that arise from this binary are: the conceptualization of indigenous places as habitats, the idea of culture as a list of traits, and the concept of “degrees” of indigeneity that determine these peoples' access to minority rights.

Thermal Modifications of Root Transparency and Implications for Aging: A Pilot Study

Root transparency has proven to be related to age and has been considered by different odontological methods for age estimation. Very little is known concerning possible variations of root transparency with heat, although the applicability of the method to burnt remains depends on the possible modifications of this specific variable. This pilot study presents the results of an experiment performed on 105 teeth obtained from dental patients and autopsy material, heated in an industrial oven at 50°C, 100°C, 150°C and 200°C. Root transparency was measured before and after the charring experiment. The heating process proved to radically modify root transparency, which decreased in 20% of samples at 50°C, in 34.6% at 100°C, in 50% at 150°C, in 77% at 200°C. The overall correlation index (CI) between decrease in root transparency and increase in temperature amounted to 0.96. These results show that heat may modify root transparency and suggest caution in using methods based on root transparency for age estimation.     

False positive and false negative rates in self-reported intentions to offend: A replication and extension

Purpose

Studies of criminal decision making commonly rely on college students’ self-reported intentions to commit a hypothetical offense. The current study evaluates the predictive validity of these intentions to offend.

Methods

Undergraduate students (n = 726) read a fictitious but seemingly realistic newspaper article describing an illegal opportunity for acquiring digital music files, and then reported their intentions to act upon the opportunity. Afterward, participants’ real world attempts to follow-through on the opportunity were monitored covertly.

Results

Findings reveal that participants who reported weak intentions to offend typically refrained from the act, resulting in a low false negative rate. However, those who reported strong intentions to offend also typically refrained from the act, thereby resulting in a high false positive rate.

Conclusions

These findings suggest that while participants’ predictions of criminal abstention are generally accurate, their predictions of criminal involvement are more problematic. Such faulty intentions have important implications for research on criminal decision making.     

A Knowledge Management and Organizational Intelligence Model for Public Administration

This study explores the development of a KM-OI model and empirically tests, using structure equation modeling (SEM), nine hypotheses related to the following research questions: RQ1: To what extent does organizational culture impact strategy structure learning with environment and information technology?; RQ2: To what extent does information technology impact learning with environment?; RQ3: To what extent does strategy structure, learning with environment impact policies and practices of KM?; RQ4: To what extent do policies and practices of KM impact organizational intelligence? Based on the results of a web survey applied in two of the six largest economies, Germany and Brazil, the article shows the importance of KM and OI for public administration and concludes that the KM-OI model is useful to identify influential factors that must be taken into consideration to improve the processes of creation (KM) and application of knowledge (OI).     

Re‐casting the politics of steel in Europe: The impact on trade unions

In this article we explore the response of European trade unions to the 1990s steel crisis. Trade unions have faced wide ranging challenges including: the globalisation of the industry; steel companies becoming increasingly international; privatisation; the eastern European steel market; the liberalisation of world trade; the new emerging priorities of the EU and internal company reorganisation. Our key argument is that their response has been highly traditional and unsuited to the new challenges. When we consider the more progressive responses they have made, there is little sign that these alternatives will be anymore successful.     

The Friendly Media Phenomenon: A Cross-National Analysis of Cross-Cutting Exposure

We hypothesize that in the real world, as opposed to the lab, the norm is for people to experience friendly media that favor their political predispositions when political favoritism is perceived at all. For this reason, media are generally limited in their ability to create cross-cutting exposure. We test this hypothesis using representative survey data drawn from 11 different countries with varying media systems. We further hypothesize that television will contribute more to cross-cutting exposure than newspapers. Finally, and most importantly, we test the hypothesis that the more the structure of a country's media system parallels that of its political parties, the more that country's population will be dominated by exposure to like-minded views via mass media. We find confirmation for all 3 of these hypotheses and discuss their implications for the role of mass media in providing exposure to cross-cutting political perspectives.
