New Formulas to Estimate Age at Death in Maya Populations Using Histomorphological Changes in the Fourth Human Rib*

Abstract: This study develops new histomorphological algorithms for Maya populations’ human ribs and tests the applicability of published algorithms. Thin sections from the fourth rib of 36 individuals of known age were analyzed under polarized light microscopy. Osteon population density (OPD, the concentration of intact and fragmented osteons per mm²), cortical area (CA), and osteon size (OS) were recorded. Seven algorithms were calculated, using all combinations of variables, and compared to the performance of published formulas. The OPD‐based formulas deviate from the known age 8.7 years on average, while those from OS and CA deviate between 10.7 and 12.8 years. In comparison, our OPD‐based algorithms perform better than the one by Stout and Paine and much better than Cho et al. In conclusion, algorithms should be developed using OPD for different ethnic groups; although Stout and Paine’s can be used for Maya and maybe Mesoamerican individuals.     

Searching the Soil: Forensic Importance of Edaphic Fauna After the Removal of a Corpse

Abstract: Arthropods at different stages of development collected from human remains in an advanced stage of decomposition (following autopsy) and from the soil at the scene are reported. The corpse was found in a mixed deciduous forest of Biscay (northern Spain). Soil fauna was extracted by sieving the soil where the corpse lay and placing the remains in Berlese–Tullgren funnels. Necrophagous fauna on the human remains was dominated by the fly Piophilidae: Stearibia nigriceps (Meigen, 1826), mites Ascidae: Proctolaelaps epuraeae (Hirschmann, 1963), Laelapidae: Hypoaspis (Gaeolaelaps) aculeifer (Canestrini, 1884), and the beetle Cleridae: Necrobia rufipes (de Geer, 1775). We confirm the importance of edaphic fauna, especially if the deceased is discovered in natural environs. Related fauna may remain for days after corpse removal and reveal information related to the circumstances of death. The species Nitidulidae: Omosita depressa (Linnaeus, 1758), Acaridae: Sancassania berlesei (Michael, 1903), Ascidae: Zerconopsis remiger (Kramer, 1876) and P. epuraeae, Urodinychidae: Uroobovella pulchella (Berlese, 1904), and Macrochelidae: Glyptholaspis americana (Berlese, 1888) were recorded for the first time in the Iberian Peninsula.     

The effect of multiple-office holding on the parliamentary activity of MPs in the Czech Republic

This article deals with multiple-office holdings by legislators in the Czech Republic during the VI. Chamber of Deputies, 2010–2013. First, both positive and negative theoretical consequences of simultaneously holding multiple political offices are depicted. Then, a uniquely detailed database of member of parliament-periods is constructed for quantitative research. Multiple-office holding is demonstrated to be a frequent behaviour among Czech deputies. The analysis results suggest that some of the deputies’ parliamentary performances were influenced both positively and negatively. Multiple-office holders probably save time on certain activities, and focus more strongly on others. Different mandates held simultaneously by deputies affect their activity differently; local and non-executive mandates’ effects tend to be positive compared with regional and executive mandates’ effects.     

Regulating intersectional activity: privacy and energy efficiency,laws and technology

Using a case study, this paper explores the extent to which one area of law (privacy and data protection) can intersect with, and be challenged by, proposals for delivery of another goal – greater energy efficiency. The article then explores the extent to which these fields are becoming more integrated; and also the risks of relying on technology (notably through Privacy by Design) to do this, particularly given the uncertainties embraced by lawyers and which can be problematic to technologists. Having identified challenges in meeting both energy efficiency and privacy/data protection goals at the same time, the article develops two responses. One looks more widely in law, to competition, to prevent particular activity and to confirm the relevance of greater legal interdisciplinarity. The other is a more multi-faceted collaborative governance approach, involving legal and technical expertise and consumer perspectives, with standards having a valuable role. Addressing climate change through greater energy efficiency should be an appropriate motivation to bring about this second approach, which draws on wider environmental governance developments. With largely a UK and EU focus, but seeking to be of transnational relevance, the paper makes key contributions as to the capacity and limits of how law can address societal challenges; explores the risks of assuming that social and legal problems can be readily addressed by technology; confirms the need for lawyers to look to other fields of law; and assists progress in an increasingly intersectional and dynamic field.     

Anxiety disorders and intimate partner violence: can the association be explained by coexisting conditions or borderline personality traits?

Intimate partner violence (IPV) is a serious, preventable public health problem. IPV perpetration is strongly associated with Anxiety disorders at the population level. We investigated whether the association could be explained by coexisting psychiatric conditions or Borderline personality traits, using a combined data-set of two National Household Surveys (n = 15,973). Results showed women were more likely to report perpetrating IPV than men. Anxiety disorders were associated with IPV. When coexisting psychiatric conditions together with a categorical diagnosis of Borderline Personality Disorder (BPD) were investigated as explanatory variables, 19.2% of the association between Anxiety disorders and IPV was explained. Using individual Borderline traits in place of a categorical diagnosis of BPD, 58.3% of the association was explained. In conclusion, the association between Anxiety disorders and IPV was partly, but not fully, explained by coexisting psychiatric conditions and individual Borderline traits. Perpetrators of IPV should be screened for Anxiety disorders and among those with Anxiety disorders, Borderline traits are important.     

The relationship between participation and managerial autonomy in cuba's basic units of cooperative production: Six case studies

We are pleased to present the following reports on library resources written by Jiri Kende, Departmental Representative of the Social Science Division of the Freie Universitat in Berlin, West Germany, and Mr. Edward P. Kasinec, chief librarian of the New York Public Library's Slavonic Division. Similar reports on other special collections in various countries will be published in forthcoming issues. Mr. Kasinec has been commissioned to write a report on Soviet libraries, which we hope will appear in the next issue.     

Computational Approach to Identify Different Injuries by Firearms

Complications arise in the analysis of gunshot wounds to the maxillofacial region, when neither the projectile nor the gun is found at the crime scene. We simulated 5‐ and 15‐cm firing distances at a human mandible to investigate the external morphology of entrance wounds based on fire range. The ammunition models, .40‐caliber S&W, .380‐caliber, and 9 × 19‐mm Luger, were constructed with free‐form NURBS surfaces. In a dynamic simulation, projectiles were fired against mandibular body 3D model at 5 and 15 cm. All entrance wounds presented oval aspect. Maximum diameter and von Mises stress values were 16.5 mm and 50.8 MPa, both for .40‐caliber S&W fired at 5 cm. The maximum energy loss was 138.4 J for .40 S&W fired at 15 cm. In conclusion, the mandible was most affected by .40‐caliber S&W and morphological differences were observable in holes caused by different incoming projectile calibers fired at different distances.
