The murderer is the bed: an unusual case of death by traumatic asphyxia in a hotel folding bunk bed

This paper presents the first referenced case on a death by traumatic asphyxia in a folding bunk bed. A middle-aged man was found dead in a hotel room trapped into a lower folding bunk bed where he had been sleeping after a party. The autopsy showed signs of asphyxia and excluded signs of struggle and sexual intercourse. Toxicological analyses revealed alcohol intoxication. A differential diagnosis of the manner of death including a technical study of the bed which contributed to understand the circumstances of death was made. The medico-legal investigation of the case strongly supported the hypothesis of an accidental death by traumatic asphyxia.     

Automation of the Differential Digestion Process of Sexual Assault Evidence,

Sexual assault evidence samples require the use of a specific process known as a differential digestion to separate sperm from nonsperm cells prior to DNA extraction. An automated differential digestion process was developed using a selective degradation technique, which uses DNase I to digest the remaining nonsperm DNA in the sperm fraction. The use of DNase on pristine samples, as well as aged and degraded samples, was assessed to ensure that the quantity and quality of the sperm DNA were not compromised or adversely affected. Samples processed using the selective degradation technique yielded comparable DNA yield and DNA typing data to the conventional differential digestion process. The automated process utilized 96‐well plates for high throughput and incorporated microscope slide preparations for confirmation of sperm. It reduced processing time by about sixfold and was paramount in the elimination of the Oakland Police Department Criminalistics Laboratory's sexual assault kit backlog.     

Reliability and validity of eight dental age estimation methods for adults

This paper evaluates the reliability and validity of eight published dental age estimation methods for adults that may aid in victim identification. Age was calculated on 20 Caucasian teeth of known age according to the methods of Kvaal (for in situ and extracted teeth), Solheim (for in situ and sectioned teeth), Lamendin (for extracted teeth), Johanson (for sectioned teeth) and Bang (for extracted and sectioned teeth) by one independent observer. For each method, mean age error and standard error were assessed as the measures of accuracy and precision. In addition, method simplicity, requirements for tooth preparation and the equipment necessary were assessed and recommendations given for forensic use in various situations. Methods for sectioned teeth gave more reliable results when compared to methods for intact teeth.     

Results of the GEP-ISFG collaborative study on the Y chromosome STRs GATA A10, GATA C4, GATA H4, DYS437, DYS438, DYS439, DYS460 and DYS461: population data

The Spanish and Portuguese ISFG Working Group (GEP-ISFG) carried out a collaborative exercise in order to asses the performance of two Y chromosome STR tetraplexes, which include the loci DYS461, GATA C4, DYS437 and DYS438 (GEPY I), and DYS460, GATA A10, GATA H4 and DYS439 (GEPY II). The groups that reported correct results in all the systems were also asked to analyse a population sample in order to evaluate the informative content of these STRs in different populations. A total of 1020 males out of 13 population samples from Argentina, Brazil, Costa Rica, Macao, Mozambique, Portugal and Spain were analysed for all the loci included in the present study. Haplotype and allele frequencies of these eight Y-STRs were estimated in all samples. The lowest haplotype diversity was found in the Lara (Argentina) population (95.44%) and the highest (99.90%) in Macao (China). Pairwise haplotype analysis showed the relative homogeneity of the Iberian origin samples, in accordance with what was previously found in the European populations for other Y-STR haplotypes (http://www.ystr.org). As expected, the four non-Caucasian samples, Macao (Chinese), Mozambique (Africans), Costa Rica (Africans) and Argentina (Lara, Amerindians), show highly significant Phist values in the pairwise comparisons with all the Caucasian samples.     

Challenges to Decentralization of Disaster Management in Turkey: The Role of Political-Administrative Context

Global disaster policy frameworks promote decentralization as a prerequisite of good disaster governance. Using 44 interviews, this study contributes to the literature that focuses on disasters and decentralization by investigating three systemic mechanisms that seemingly challenge decentralization of disaster management in Turkey: introduction of oversight systems, resource-allocation failure, and central–local collaboration. The results indicate that these mechanisms are enabled by a combination of political-administrative system characteristics and disaster-induced processes. To better understand how to secure the benefits of decentralization, we should engage with a wide range of disaster management actor perspectives, and integrate research on political-administrative systems and collaborative governance.     

“It’s Like Standing on a Beach,Holding Your Children’s Hands,and Having a Tsunami Just Coming Towards You”: Intimate Partner Violence and “Expert” Assessments in Australian Family Law

The ways in which postseparation parenting disputes are managed has undergone significant change in Australia since the Family Law Act (Cth) was first enacted in 1975. The best interests of children have always been paramount in children’s cases and over the last 20 years, this concept has been legislatively shaped to include ongoing beneficial post separation parental relationships and protection from harm. A critical piece of evidence to inform a Family Court’s decision making in such matters is a family report, which is an expert assessment compiled by a social science professional. The authors report findings from an Australian based qualitative study exploring the experiences of family report assessment practice from the perspective of victim mothers who have separated from men who perpetrate intimate partner violence. The authors conclude that reforms are necessary to improve the practice and procedure of family report writing in Australia. Such reforms should ensure that the lived experience of victims of intimate partner violence is validated, assessment processes have victim efficacy, and the outcomes of such reports do not put women and their children at ongoing risk of harm.     

Why Missing Data Matter in the Longitudinal Study of Adolescent Development: Using the 4-H Study to Understand the Uses of Different Missing Data Methods

The study of adolescent development rests on methodologically appropriate collection and interpretation of longitudinal data. While all longitudinal studies of adolescent development involve missing data, the methods to treat missingness that have been recommended most often focus on missing data from cross-sectional studies. The problems of missing data in longitudinal studies are not described well, there are not many statistical software programs developed for researchers to use, and there are no longitudinal empirical examples involving adolescent development that show the extent to which different missing data procedures can yield different results. Data from the first three waves of the 4-H Study of Positive Youth Development were used to provide such an illustration. The sample contains 2,265 participants (56.7% females) who were in Grade 5 at Wave 1, in Grade 6 at Wave 2, and in Grade 7 at Wave 3, and varied in race, ethnicity, socioeconomic status, family structure, rural–urban location, and geographic region. The results showed that three missing data techniques, i.e., listwise deletion, direct maximum likelihood (DirML), and multiple imputation (MI), did not yield comparable results for research questions assessing different aspects of development (i.e., change over time or prediction effects). The results indicated also that listwise deletion should not be used. Instead, both DirML and MI methods should be used to determine if and how results change when these procedures are employed.     

Biologising Paternity,Moralising Maternity: The Construction of Parenthood in the Determination of Paternity Through the Courts in Portugal

This article explores how the Portuguese legal system’s efforts to determine paternity of children born outside legal marriage, automatically initiated by the Registry Office when a birth registration does not indicate the father, reveal cultural models which reinforce the naturalisation of the differences between mothers and fathers, with significant effects on the social construction of parental roles and on expectations of family organisation and female sexual behaviour. The article relies on ethnographic data drawn from direct observation of court proceedings for the determination of paternity, as well as interviews with judges and prosecuting counsels all over the country. It is argued that judicial practices in the specific context of courtroom investigations of paternity reinforce gender inequalities in two interrelated ways. On the one hand, they are strengthened in the discursive practices performed during the course of the interactions between judges, prosecuting counsels and the mother of the child, as well as the alleged father. On the other hand, the normative model of family life and the dominant ideology of women’s and men’s relationships, which emphasise women’s socially subordinate position, are revealed by the selective use of DNA testing in paternity cases, based on the judge’s evaluation of the mother’s sexual behaviour. The article argues that legal attempts to establish the paternity of children born outside marriage—though based on novel technical and supposedly objective procedures—tend, nevertheless, to reproduce the prevailing patriarchal structures.

Gender and Corruption: The Mediating Power of Institutional Logics

Scholars have argued that recruiting more women to office is an effective way to curb corruption; however, the more precise mechanisms underlying why this may be the case have remained unclear. We use meso‐level theories to elaborate on the relationship and suggest that institutional logics mediate the effect of gendered experiences on corruption. We make two propositions: First, we suggest that the relationship between more women and lower levels of corruption is weaker in the state administration than in the legislative arena, because the bureaucratic administrative logic absorbs actors’ personal characteristics. Second, we refine our institutional argument by claiming that the stronger the bureaucratic principles are in the administration, the less gender matters. We validate our theory using data provided by the European Commission (EC) covering the EC countries and original data from the Quality of Government Institute Expert Surveys, covering a larger set of countries on a worldwide scale.
