Two fatal intoxication cases with imidacloprid: LC/MS analysis

Imidacloprid [1-(6-chloro-3pyridylmethyl)-N-nitroimidazolidin-2-ylideneamine] is a new and potent nitromethylene insecticide with high insecticidal activity at very low application rates. It is the first highly effective insecticide that, like nicotine, acts on the nervous system, causing blockage of postsynaptic nicotinergic acetylcholine receptors. Two fatal cases with this insecticide in two male individuals, of 33 and 66 years old, are presented. An LC/MS with electrospray method for measuring imidacloprid and its metabolites in post-mortem samples is described. In the chromatographic separation, a reverse-phase column XTerra MS C18 (2.1mm i.d.x 150 mm, 5 microm) was used and the mobile phase composed with acetonitrile and 0.1% formic acid (15:85), at a 0.25 mL/min flow rate. Samples were prepared with a liquid-liquid extraction procedure with dichloromethane. Calibration curves for imidacloprid in blood and urine samples were linear from 0.2 to 15 microg/mL. The mean recovery was 86% with a coefficient of variation of +/-5.9%. The detection limit was 0.002 microg/mL. Quantitative results were obtained for all post-mortem matrices available of the two fatal cases: blood, urine, stomach contents, lung, liver and kidney. The imidacloprid blood concentrations found in two-cases were 12.5 and 2.05 microg/mL. The authors validated a method to detect and quantify imidacloprid in post-mortem samples, and to our knowledge for the first time a post-mortem tissue distribution was performed on various samples for this insecticide.     

Gender Bias in Attributions of Responsibility for Abuse

The bulk of previous research investigating attributions of responsibility in victimization scenarios have portrayed the assailant as male and the victim as female. The present study varied gender of the participant, gender of the assailant, and gender of the victim in order to examine gender bias in attributions of responsibility in abuse scenarios. Male and female participants were presented with scenarios depicting an abusive interaction between two males, two females, or a male and a female character and then made judgements of responsibility either with or without the narratives present. The results indicated that attributions made by females were biased against male victims of a male assailant when judging actions of the assailant. Attributions made by females and, to a lesser degree, attributions made by males were biased against the victim when the assailant and the participant were of the same gender and attributions of assailants' actions were made without the narrative present. In the analysis of attributions of actions of the victim, males attributed more responsibility to male than female victims. It is concluded that gender of all parties may be an important consideration when judging responsibility in victimization scenarios.     

The decision process of a professionalized legislature: A cognitive anthropology approach

Political science research indicates that some state legislatures have become more professionalized, i.e., taken on many of the characteristics of Congress such as yearround sessions, professional staffs, and formalized bill processes. But is professionalization a factor in legislators' decision making? Triangulated analysis—consensus, cluster, and multidimensional scaling—of two paired comparisons that were administered to a stratified random sample of a professionalized legislature suggests that some of the professionalized characteristics do affect legislators' perception of their decision making on one area of policy, the regulation of and resource allocation to public universities. The analysis also shows that influences on legislators' decision process fluctuate according to issue.     

DNA typing of short tandem repeat loci on Y-chromosome of Greek population

Haplotype, allele frequencies and population data of nine Y-chromosome STR loci, DYS385I, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, were determined from a sample of 69 unrelated Greek male individuals.     

NGO strategies beyond aid: Perspectives from Central and South America and the Philippines

Though unevenly spread, many developing countries are experiencing a decline in aid flows. This paper explores and compares NGDO responses in regions and countries in or entering a 'beyond-aid scenario'. The comparison shows that, despite a diversity of contexts and histories, the quest for self-sustainability has become a common and dominant concern. Within a framework of options, examples show what is being attempted in terms of NGDOs altering their resource profile and the problems they encounter in doing so. Emerging evidence suggests that NGDOs are more likely to sustain themselves if they (a) look beyond finance to adopt an integrated, capacity-based approach to sustainability and internal organisational reform and (b) put effort into making good their 'relational deficit' with a wider array of domestic constituencies.     

An investigation into the enhancement of fingermarks in blood on paper with genipin and lawsone

The abilities of two natural products, genipin and lawsone, to enhance blood contaminated fingermarks on papers of various porosities and colour were investigated and compared to the routinely used amino acid reagents, ninhydrin and 1,8-diazafluoren-9-one (DFO).Fingermarks in blood were deposited as a split depletion series on various paper types and colours for ageing periods of 6 weeks, 4 weeks, 2 weeks and 1 week before enhancement. The developed marks were observed under different lighting conditions, recorded and graded by way of attributing quantitative data to each series.Results indicated that while genipin showed some potential as a reagent for the enhancement of latent fingermarks, it displayed no suitability for the enhancement of fingermarks in blood on paper. Lawsone also failed to successfully enhance either type of fingermark. Upon comparison of the results with those of ninhydrin and DFO it was found that ninhydrin displayed the highest success rate of development of these marks.
