Vertical Lip Position and Thickness in Facial Reconstruction: A Validation of Commonly Used Methods for Predicting the Position and Size of Lips

This study examined several methods used to estimate oral fissure position, lip margin position, and lip thickness recommended by Angel, George, Lebedinskaya, Taylor, Wilkinson et al., Balueva and Veselovskaya. A sample of 86 lateral head cephalograms of adult subjects from central Europe were measured and the actual and predicted dimensions were compared. The best estimation for oral fissure position was “opposite the lower ¾ mark of maxillary incisors” (error of 1.3 mm). Upper lip margin was predicted best by “upper ¼ mark of maxillary incisors” (error of 1.7 mm), and lower lip margin by “cementum‐enamel junction of mandibular incisors” (error of 2.3 mm). The regression equations of Wilkinson et al. displayed least error (1.3 mm and 1.8 mm, respectively) for upper and lower lip thickness, and method of George (error of 3.4 mm) for total lip thickness.     

The organizational structure of international drug smuggling

While most group offending is not well organized, it is generally assumed that high levels of organization can be found in group offending that generates revenue, such as white-collar crime, drug sales, and smuggling drugs or humans. The organizational structure of international drug smuggling has typically been viewed as highly rational and formally structured. Employing interviews with thirty-four federal prisoners convicted of smuggling large volumes of cocaine into the United States, this study explored the organizational structure of high level international drug smuggling. The subjects described a general lack of formal structure and depicted the drug smuggling operations as composed of isolated work groups without formal connections among each other. These findings bring into question the idea that these groups are rationally organized around pursuing efficiency and support recent research that suggests network security or minimizing risk are key organizing principles of drug trading organizations.     

Interviewing serious offenders: Ms. Egghead meets Mr. Gumshoe

Organised crime, due to its intricate nature, is a very challenging as well as less accessible research field. Although difficult to conduct a methodical research on this topic, organised crime, nevertheless, offers a unique opportunity to utilise an interdisciplinary research methodology. This paper describes (multiple) triangulation as an appropriate method for researching the role of culture in the advancement of ethnic Albanian organised crime groups in Europe. Triangulation, for the purpose of the described project, has been used to obtain confirmation of findings through convergence of different perspectives. Interviewing offenders is one of the research methods more thoroughly explained in this paper. The paper too explores some advantages of snowball technique used for interviewing less accessible research subjects. It also discusses various dilemmas, security-related or not, researchers are faced with when intending to interview serious offenders.

Multinational Corporations and Service Provision in Sub‐Saharan Africa: Legitimacy and Institutionalization Matter

This article considers attempts by multinational corporations to provide services in areas of limited statehood. Under which conditions are such attempts effective? We make two arguments: First, they must be legitimate to be effective. Second, the institutional design of the firms’ service provision programs is an important factor for their effectiveness. We assess these arguments by analyzing multinationals in the South African car industry fighting HIV/AIDS, and international mining firms in South Africa and the Democratic Republic of Congo trying to improve public security. The analysis demonstrates that under conditions of legitimacy and high degrees of institutionalization firm programs effectively contribute to service provision in areas of limited statehood.     

Dominican Party System Continuity amid Regional Transformations: Economic Policy,Clientelism, and Migration Flows

In the 1980s and 1990s, economic crisis produced ideological convergence in many Latin American party systems. Much scholarship explores how this convergence frequently provoked system change that enabled renewed ideological differentiation, but little research examines instances where convergence persisted without destabilizing the system. Through comparative historical analysis of Dominican continuity amid regional change, this study identifies factors that sustain or challenge party systems. Then, through analysis of Americas Barometer surveys, it assesses the causal mechanisms through which these factors shape support for the traditional Dominican parties. The findings demonstrate that maintaining programmatic and clientelist linkages facilitates continuity. In addition, the article argues that the threats political outsiders pose to existing party systems are constrained when people excluded from the system are divided and demobilized. In the Dominican case, Haitian immigration divides the popular sector while Dominicans abroad sustain ties to the parties, with both migration flows facilitating party system continuity.     

Comparison of methods to determine sex by evaluating the greater sciatic notch: Visual, angular and geometric morphometrics

Sex estimation is the first step for biological profile reconstruction of an unknown skeleton (archaeological or contemporary) and consequently for positive identification of skeletal remains recovered from forensic settings. Several tools have been developed using different osseous structures. With the intention to provide an objective method comparison, we reported the analysis of three different methods (visual, metric and geometric morphometrics) for sex assessment of the greater sciatic notch. One hundred and thirty pelvic bones (45.4% females and 54.6% males) from the National Autonomous University of Mexico Skeletal Collection pertaining to the contemporary Mexican population were analyzed. We used the ROC-analysis to test between desired false positive thresholds (1-specificity) and expected true positive rates (sensitivity) in order to predict the best approach to sex assessment. The comparison of the area under the ROC-curves shows significant differences among visual and metric methods. At the same time, the analysis suggested that higher morphological variation among the sexes is independent of the methodological approach. The results indicate that the metric (angle), with a high percent of indeterminate cases (34.6%), and visual, with 26.2% of the cases allocated as intermediate cases, were poorly accurate; we cannot recommend these techniques for sexing an unknown specimen. On the other hand, the geometric morphometrics approach improves sex estimation in 82.3% of correctly classified individuals with more than 95% of posterior probability. In addition to the method comparison, the major sexual variation of the greater sciatic notch was determined to be located on its posterior border.
