The Zuma Affair,Labour and the Future of Democracy in South Africa

This review article critically analyses the contribution of Amartya Sen's The Idea of Justice to development studies. On the basis of examples of unjust situations derived from Sen's writings, the article discusses the limited reach of The Idea of Justice in addressing concrete cases of injustice. It contends that remedying injustice requires an understanding of how justice is structural, which recognises that discussion of justice is inseparable from reasoning about the nature of the good society. The article concludes by pointing out The Idea of Justice's ambiguous relationship with liberalism.     

Development of the Social Issues Advocacy Scale-2 (SIAS-2)

The 21-item Social Issues Advocacy Scale (SIAS; Nilsson, Marszalek et al. in Educ Psychol Meas 71(1):258–275, 2011) was developed as a concise measure of social justice advocacy for people in the helping and health professions. Recent scholarship has indicated a need for a broader measure. The present study seeks to continue development of the SIAS into an expanded version, the SIAS-2. A sample of 284 helping and health professionals and college students in related fields was administered 117 items, which was reduced to 78 items for the final instrument through item analysis and exploratory factor analysis. Eight factors emerged explaining 61.5% of the item variance. Corresponding subscales ranged in reliability from .88 to .94. Additional validity evidence is discussed.     

Latino Adolescents’ Civic Development in the United States: Research Results from the IEA Civic Education Study

Many studies have reported gaps between Latino and non-Latino adolescents in academic and political outcomes. The current study presents possible explanations for such gaps, both at the individual and school level. Hierarchical linear modeling is employed to examine data from 2,811 American ninth graders (approximately 14 years of age) who had participated in the IEA Civic Education study. Analyses of large data bases enable the consideration of individual characteristics and experiences, as well as the context of classrooms and schools. In comparison with non-Latino students, Latino adolescents report more positive attitudes toward immigrants’ rights but have lower civic knowledge and expected civic participation. These differences were apparent even when controlling for language, country of birth, and political discussions with parents. School characteristics that explain a portion of this gap include open classroom climate and time devoted to study of political topics and democratic ideals. Results are discussed within the framework of developmental assets and political socialization. Implications for educational policy and ways to use large data sets are also discussed.

Characteristics and Prediction of Cranial Crush Injuries in Children*†

Abstract: This study documents four clinical cases of fatal crush injuries to children between 1.5 and 6 years of age with correlations between modeled stress and clinically observed fracture patterns. The clinical case fractures were concentrated in the basicranium, bridged the impact sites, and traversed the middle cranial fossa in the area of the spheno‐occipital synchondrosis. The crushing forces from these cases were recreated on a simplified finite element model of a cranium by applying bilateral pressures to corresponding regions. Numerous trials were run to develop a representative pattern of principal stress directions. In all cases, the highest tensile stresses were located on the basicranium and corresponded to the observed fracture path(s). These results suggest that prefailure stress field diagrams may predict fracture propagation paths, although these will not be exact. Also, these analyses indicate that quasi‐static bilateral loading of the cranium may lead to predictable fracture of the basicranium.     

FUTURE CHILD'S RIGHTS IN NEW REPRODUCTIVE TECHNOLOGY:THINKING OUTSIDE THE TUBE AND MAINTAINING THE CONNECTIONS

This article considers whether children born through assisted human reproduction are entitled to information about their biological origins. It examines the issue both from a clinical perspective, citing social science research and the personal narratives of donor‐conceived children, and from a legal perspective, outlining the extent of a child's “right to know” in different jurisdictions. The article suggests that a uniform legal approach is needed that will recognize the right of all children to access details about their identity and conception, for the sake of their psychological well‐being. The article includes a fact scenario that considers the situation of a donor‐conceived child who has become the subject of a custody dispute, and who has not been told the circumstances of his conception.     

Rapid amplification of commercial STR typing kits

Forensic DNA typing is currently conducted in approximately 8–10 h. The process includes DNA extraction, quantitation, multiplex PCR amplification, and fragment length detection. Today's commercial multiplex short tandem repeat (STR) typing kits are not optimized for rapid PCR thermal cycling. Current protocols require approximately 3 h for amplifying a multiplex containing 15 STR loci plus amelogenin. With the continuing development of miniaturization technologies such as microfluidic and micro-capillary devices, there is a desire to reduce the overall time required to type DNA samples. Such miniature devices could be used for initial screening at a crime scene, at a border, and at airports. There is also the benefit of reducing the required PCR amplification time for labs typing single-source reference samples. Surveys of fast processing polymerases working in combination with rapid cycling protocols have resulted in the development of a ‘rapid’ PCR amplification protocol. Results are obtained in less than 36 min run on a standard peltier-based thermal cycler employing a heating rate of 4 °C/s. Capillary electrophoresis characterization of the PCR products indicates good peak balance between loci, strong signal intensity and minor adenylation artifacts. Genotyping results are concordant with standard amplification conditions utilizing a standard 3 h (non-rapid) thermal cycling procedure. The rapid assay conditions are robust enough to routinely amplify 0.5 ng of template DNA (with 28 cycles).     

A 26plex Autosomal STR Assay to Aid Human Identity Testing*†

Abstract: A short tandem repeat multiplex assay has been successfully developed with 25 autosomal loci plus the sex‐typing locus amelogenin for a total of 26 amplified products in a single reaction. Primers for the loci were designed so that all of the amplicons present were distributed from 65 base pairs (bp) to less than 400 bp within a five‐dye chemistry design with the fifth dye reserved for the sizing standard. A multiplex design strategy was developed to overcome challenges encountered in creating this assay. The limits of the multiplex were tested, resulting in the successful amplification of a wide range of genomic DNA sample concentrations from 2 ng to as low as 100 pg with 30 cycles of PCR. The 26plex has the potential to benefit the forensic community for reference sample testing and complex relationship evaluation.
