Immunohistochemical analysis of forensic evidence from a double homicide

We report the use of immunohistochemical staining for analysis of forensic evidence from a double homicide. A 38-year-old woman and her 7-year-old daughter were murdered by multiple blows to the head and face with a tomahawk, resulting in multiple fragments of brain tissue scattered about the murder scene. The victims' husband and father was the main suspect, who maintained that he was out of town on business during the evening of the murders. However, a shirt taken from the suspect's car on the morning after the murders (secured by the police before the suspect visited the murder scene) was found to have two small stains. DNA analysis on the stains showed the presence of the deceased wife's DNA, and immunohistochemical stains on shirt fragments conclusively documented the presence of deep central nervous system tissue, providing the critical piece of evidence needed to arrest and prosecute the suspect. This report demonstrates that shirt or similar cloth fragments can be processed into paraffin blocks and subsequently immunostained to search for and classify types of tissue fragments that may be present on the fabric.     

Characterization of the Caucasian haplogroups present in the SWGDAM forensic mtDNA dataset for 1771 human control region sequences. Scientific Working Group on DNA Analysis Methods

Currently, the Scientific Working Group on DNA Analysis Methods (SWGDAM) mtDNA dataset is used to infer the relative rarity of mtDNA profiles (i.e., haplotypes) obtained from evidence samples and for identification of missing persons. The Caucasian haplogroup patterns in this forensic dataset have been characterized using phylogenetic methods. The assessment reveals that the dataset is relevant and representative of U.S. and European Caucasians. The comparisons carried out were both the observation of variable sites within the control region (CR) and the selection of a subset of these sites, which partition the variation within human mtDNA control region sequences into clusters (i.e., haplogroups). The aligned sequence matrix was analyzed to determine both single nucleotide polymorphisms (SNPs) in a phylogenetic context, as well as to check and standardize haplogroup designations with a focus on determining the characters that define these groups. To evaluate the dataset for forensic utility, the haplogroup identifications and frequencies were compared with those reported from other published studies.     

Postcranial Sex Estimation Criteria for Mexican Hispanics

Population-specific reference data are necessary for sex estimation in forensic anthropological practice. Currently, there are no population-specific data for Hispanics equivalent to data available for American Blacks and Whites. Individuals of Mexican origin represent the largest group of Hispanics in the United States (Spradley and Jantz. 2011. J Forensic Sci;56:289). This paper presents new population-specific sex estimation criteria for postcranial measurements for Mexican Hispanics. Metric data come from positively identified border-crossing fatalities at the Pima County Office of the Medical Examiner and documented cemetery collections curated at Universidad Nacional Autónoma de México and Universidad Autónoma de Yucatán. Stepwise variable selection procedures and discriminant function analyses were utilized to generate classification functions for postcrania. Sectioning points were also created for select measurements. Both the cross-validated classification rates and sectioning points achieved accuracy rates as high as 95% and 92%, respectively. These new criteria will improve sex estimation for US Mexico border crossers and Hispanics in the US.     

Does the Charter Form Improve the Fiscal Health of Counties?

The public administration literature has paid attention to the relationship between the structure of a government and its ability to provide public services, reflected by its fiscal health. Although this literature has provided a useful understanding of government structures, it has largely ignored the charter form of government. As a formal written document that grants counties the power of self‐governance, a charter frees the county from state control. Included in this freedom is the ability to establish its own tax policies and services. In this article, the effects of charter adoption on fiscal health are tested using Florida county data from 1980 to 2012. The results show that the presence of a charter can improve the fiscal health of a county, which, in turn, can affect overall service provision.     

Research and productivity in wheat in Israel

The introduction of the new Green Revolution wheat varieties to Israel is reviewed and analysed. It was found that the first stage varieties (developed from local Mexican wheats) did not have a significant impact on yields in Israel. Dwarf varieties and new crosses bred in Israel from Mexican genetic material contributed significantly to yield increases. Returns to local research are estimated. Conclusions about the role of the International Research System are drawn.     

Professionalization within a traditional political culture: A case study of south carolina

This article examines the progress of professionalization within a highly traditional political and social setting. The impact of such characteristics as a decentralized personnel system, fragmented political authority, and an absence of top-level support is assessed in the context of current initiatives to upgrade the professional orientations and capabilities of the state's workers. The primary theme is that, despite the lack of an integrated professionalism movement in state government, remarkable advances have occurred, and are continuing at an impressive pace. The impetus for these changes is found to be in the various employee groups that are striving to enhance their professional skills and status.     

Factors Associated with the Performance of User Groups in a Participatory Forest Management around Dodola Forest in the Bale Mountains,Southern Ethiopia

This study analysed and determined factors associated with performance in collective action of a forest under participatory forest management in Southern Ethiopia. Data were collected in 22 user groups and a performance index was computed using indicators including forest cover change, households' perception of the change and satisfaction in their livelihoods, management activity, and length of overdue rent payment. The results show that heterogeneity, level of forest dependence and geographical variables such as altitude and distance to town are important variables that may affect the performance of user groups. The findings indicate the importance of taking into account the needs of members of user groups, differences among local people in dependence on forest income, and differences in values attached to the forest in the design of participatory forest management.     

Credit access,human capital and class structure mobility

This article examines the impact of microenterprise credit programmes on class structure mobility in developing countries. It develops a model that endogenously generates an eight‐fold class structure. Class membership is determined by optimal choice of labour activity, which is a function of access to credit and human capital endowments. Predictions from the model suggest that better access to credit will foster upward class mobility among self‐employed entrepreneurs, and that this upward class mobility will be accentuated among entrepreneurs with high levels of human capital. Theoretical predictions from the model are compared with data on class structure mobility collected first‐hand in western Guatemala. Empirical results show that upward class structure mobility increases substantially with access to credit, and also suggest that the combined effect of innate entrepreneurial ability and credit access has a greater impact on upward class structure mobility than the interaction between formal schooling and credit access.
