Courtship violence using couple data: characteristics and perceptions

This study examined courtship violence using couple data. Participants were 50 heterosexual dating couples with at least one member of the couple being a university student. Using the Conflict Tactics Scales 2 (CTS2), both members of a couple reported on received and inflicted physical and psychological violence. The prevalence of physical aggression depended on how violence was defined. On the CTS2, 60% of couples were considered physically violent when within-couple agreement was not considered; this dropped to as low as 28% when agreement had to be present. Women were more likely than men to report inflicting psychological aggression and to report aggressing against their partner with a playful intent. Taken together, these findings demonstrate the need to continue to examine courtship violence, especially by utilizing responses from both members of a couple.     

The EDNAP mitochondrial DNA population database (EMPOP) collaborative exercises: organisation, results and perspectives

This paper presents an overview of the organisation and the results of the collaborative exercises (CE) of the European DNA Profiling (EDNAP) Group's mitochondrial DNA population database project (EMPOP). The aim of the collaborative exercises was to determine whether uniformity of mtDNA sequencing results could be achieved among different laboratories. These were asked to sequence either the complete mtDNA control region or the two hypervariable regions HVI (16024-16365) and HVII (73-340) from DNA extracts, buccal swabs or bloodstains, proceeding in accordance with the protocol and strategies used in each individual laboratory. The results of the collaborative exercises were employed to identify possible sources of errors that could arise during the analysis and interpretation of mtDNA profiles. These findings were taken as a basis to tentatively make suitable arrangements for the construction of a high quality mtDNA database. One hundred fifty mtDNA profiles were submitted to the evaluating laboratory, and disaccording profiles were classified into four groups corresponding to the source of error: clerical errors, sample mix-ups, contaminations and discrepancies with respect to the mtDNA nomenclature. Overall, 14 disaccording haplotypes (16 individual errors) were observed. The errors included 10 clerical errors, 3 interpretation problems, 2 cases of sample mix-up and 1 case of point heteroplasmic mixture, where the 2 sequencing reactions brought inconsistent base calls. This corresponds to an error rate of 10.7% in a virtual mtDNA database consisting of the collaborative exercise results. However, this estimate is still conservative compared to conclusions drawn by authors of meanwhile numerous publications critically reviewing published mtDNA population databases. Our results and earlier published concerns strongly emphasize the need for appropriate safety regulations when mtDNA profiles are compiled for database purposes in order to accomplish the high standard required for mtDNA databases that are used in the forensic context.     

Preparation of degraded human DNA under controlled conditions

DNA typing through analysis of short tandem repeats (STRs) and mitochondrial DNA (mtDNA) by means of the polymerase chain reaction (PCR) and sequencing are the common methods for the forensic identification of persons and reconstruction of kinship, especially when skeletal human remains have to be analyzed. Furthermore, samples typically found at crime scenes may be both quantitatively and qualitatively inadequate since they may contain very scarce and often degraded DNA due to exposure to heat, light, humidity, and microorganisms. In order to improve the performance of STR typing technology in those cases where DNA availability is limited, it would be desirable to have a source of degraded DNA with known properties. For this purpose, we have developed a method to prepare artificially degraded DNA under controlled conditions. By treatment of genomic DNA with sonication and DNAse I we have produced DNA fragments within a defined range of lengths. STR typing of this degraded DNA with a commercially available multiplex kit could only produce partial profiles as indicated by the absence of STR alleles with sizes >200 bp. This artificially degraded DNA can be used for the improvement and standardization of STR typing protocols when only highly degraded DNA is available for analysis.     

Integrating Critical Race Theory and Postmodernism Implications of Race, Class, and Gender

This paper begins with an overview of criticalrace theory tenets, which in turn will befollowed by an overview of postmodernism. These bodies of knowledge consist of an arrayof ideologies; but for the purpose of thisarticle only the fundamentals of each will bediscussed. Thereafter, an integration ofthese two contemporary areas of thought willdemonstrate the constructive linkage ofcritical race theory and postmodern theory. Theintegrations that follow will emphasize how acollaboration of critical race theory tenetsand postmodern thought can contribute to asuccessful, and more importantly improved,analysis of the social constructions of race,class, and gender. In addition, theintersectional analysis presented willdemonstrate a more informative and betterunderstanding of the subtleties of blatant andmore hidden forms of race, class, and gender.     

Die Prognosegüte von Wahlbörsen und Meinungsumfragen zur Bundestagswahl 2005

In the aftermath of an election it has become customary to systematically compare the predictive accuracy of polls and political stock exchanges. However, most of these analyses do not emerge from real predictions. In this research note, we compare the predictive performance of a time-series model to the accuracy of polls and a political stock market in the 2005 german Bundestag (general) election. Our analysis shows that Wahl$treet, the most significant german political stock exchange, was again closest to the actual results leaving commercial polling institutes behind. Due to the exceptionally large errors of most institutes we briefly discuss how such inaccurate forecasts might affect voting behaviour in the light of social choice theory.     

Community‐Based Participatory Research as a Tool for Policy Change: A Case Study of the Southern California Environmental Justice Collaborative

In 2000, a regional rule governing maximum individual cancer risk from stationary facilities in Southern California was dramatically altered, reducing allowable risk levels by 75%. This article uses a case study approach to explore the role of a community‐based participatory research (CBPR) partnership, the Southern California Environmental Justice Collaborative, in producing research and helping spearhead policy advocacy leading to this policy change. It also highlights the role of the collaborative in helping to change the framing of the issue from individual to cumulative risk assessment, so that the regulatory agencies began to reflect this broader thinking in their policymaking. The collaborative's structure and methodology, regional focus, relationships with key decision makers, and its reputation as an important source of both credible science and “people power” were seen as contributing to its effectiveness. The role of contextual factors including a recovering and more regulation‐friendly economy also is highlighted, as are key barriers faced. Implications for other community–academic partnerships working to address regional and statewide public policy are discussed.     

Allele sharing in first-degree and unrelated pairs of individuals in the Ge F I AmpFlSTR Profiler Plus database

Eleven Italian forensic laboratories participated in a population study based on the AB Profiler Plus loci with proficiency testing. The validated database, including 1340 individuals, is available on-line. Tests for Hardy-Weinberg equilibrium, gametic unbalance, and heterogeneity of gene frequency were generally not significant. Gene frequencies at each locus were consistent with those of two previously published Italian studies, but different from a third. Individuals of each subsample were paired, and the total number of alleles shared across the nine loci was determined in each pair. The analysis was replicated over the total sample. In addition, two samples of mother-child pairs (N=315) and full-sib pairs (N=91) were subjected to allele sharing analysis. The resulting distributions were sufficiently distinct from the sample of unrelated pairs as to be of practical usefulness.     

Global Governance through Private Organizations

Governance at international and global levels is not only provided through states and markets but also through a variety of private organizations. The business world is well represented through this kind of organization and contributes to global governance through self-regulation across a number of industries. This article examines these efforts in the encompassing organization of global commerce, in the pharmaceutical industry and among dye stuffs producers. Smaller organizations are generally better suited to monitor compliance and impose sanctions on members violating the codes and norms behind self-regulation. Even small organizations, however, are confronted with problems and there is also evidence of large and very complex organizations having established effective mechanisms as alternatives to public regulation. These experiences can be built into theories on self-regulation as a form of global governance.
