Examination of the steps leading up to the physical developer process for developing fingerprints

This is a systematic study that examines several acid prewashes and water rinses on paper bearing latent prints before its treatment with a silver physical developer. Specimens or items processed with this method are usually pretreated with an acid wash to neutralize calcium carbonate from the paper before the treatment with a physical developer. Two different acids at varying concentrations were tested on fingerprints. Many different types of paper were examined in order to determine which acid prewash was the most beneficial. Various wash times as well as the addition of a water rinse step before the development were also examined. A pH study was included that monitored the acidity of the solution during the wash step. Scanning electron microscopy was used to verify surface calcium levels for the paper samples throughout the experiment. Malic acid at a concentration of 2.5% proved to be an ideal acid for most papers, providing good fingerprint development with minimal background development. Water rinses were deemed unnecessary before physical development.     

Haplotype diversity of 16 Y-chromosomal STRs in three main ethnic populations (Malays, Chinese and Indians) in Malaysia

We have analyzed 16 Y-STR loci (DYS456, DYS389I, DYS390, DYS389II, DYS458, DYS19, DYS385a/b, DYS393, DYS391, DYS439, DYS635 or Y-GATA C4, DYS392, Y-GATA H4, DYS437, DYS438 and DYS448) from the non-recombining region of the human Y-chromosome in 980 male individuals from three main ethnic populations in Malaysia (Malay, Chinese, Indian) using the AmpFlSTR((R)) Y-filertrade mark (Applied Biosystems, Foster City, CA). The observed 17-loci haplotypes and the individual allele frequencies for each locus were estimated, whilst the locus diversity, haplotype diversity and discrimination capacity were calculated in the three ethnic populations. Analysis of molecular variance indicated that 88.7% of the haplotypic variation is found within population and 11.3% is between populations (fixation index F(ST)=0.113, p=0.000). This study has revealed Y-chromosomes with null alleles at several Y-loci, namely DYS458, DYS392, DYS389I, DYS389II, DYS439, DYS448 and Y-GATA H4; and several occurrences of duplications at the highly polymorphic DYS385 loci. Some of these deleted loci were in regions of the Y(q) arm that have been implicated in the occurrence of male infertility.     

(Re-)building governance in post-conflict Africa: the role of the state and informal institutions

Post-conflict governance is an increasingly important aspect of foreign development assistance in sub-Saharan Africa (SSA), where the weakening and disintegration of the state undermine sustainable human development. A major challenge in post-conflict rebuilding in SSA concerns the incorporation of subnational non-state structures and informal institutions into the post-conflict governance apparatus. In order to tackle this apparent gap in sustainable peacebuilding, more theoretical and empirical research is needed into the nuanced role(s) and contribution(s) of the post-conflict state in reconstituting governance and rehabilitating communities. This article discusses the post-Washington Consensus (PWC), an emerging development approach which seeks to re-introduce the role of the state in development and post-conflict studies. The central proposition of the article is that, contrary to the anti-statist premise of the Washington Consensus, states, non-state structures, and informal institutions play an important role in cultivating institutional reconciliation, interpenetration, and integration between macro-level government structures and subnational social institutions.     

The Relative Resilience of Property: First Possession and Order Without Law in East Timor

Much of the recent literature on customary property relations in sub‐Saharan Africa has highlighted underlying characteristics of negotiability and indeterminacy. Custom is prone to reinvention as resource claimants manipulate customary references across multiple forums for property legitimation and authority. This article focuses on the resilience of customary property relations in East Timor. Based on a study of customary authority in the village of Babulo, we conclude that traditional Timorese narratives of first possession, where land authority is claimed by groups that trace descent to a mythic first settler, have acted as adaptive and resilient focal points for the reproduction of customary property relations in historical circumstances of war, colonization, and occupation. While a finding of customary resilience is not new to postcolonial contexts, the relative novelty of our study lies in its structured explanation for resilience in circumstances of war and displacement, based on the social ordering capacity of first possession principles themselves. This explanation, which derives from focal point theories for cooperative property relations, also takes into account a number of limits on the ordering capacity of first possession principles, which support a conclusion of relative or constrained resilience, particularly in terms of contested interpretations of possessory authority in contemporary East Timor.
