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.  相似文献

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.  相似文献

“Forces in the broader political arena have periodically opened windows of opportunity for major policy change in the health care arena. The systems that resulted were largely, if not entirely, ‘accidents' of the timing of their births.” Accidental Logics: The Dynamics of Change in the Health Care Arena in the United States, Britain, and Canada.

In late 2022, Israel and Lebanon signed a US-brokered maritime agreement establishing their permanent maritime boundary and exclusive economic zones, and regulating their rights to gas exploration in the eastern Mediterranean. Preceding the agreement was a sustained coercive-diplomacy campaign by Hezbollah. Between June and October, the organization conveyed overt and covert threats, and it pursued actions that were unprecedented in the Israel-Hezbollah conflict: openly threatening to target Israel's entire gas production and risk all-out war if Israel proceeded with its plan to unilaterally extract gas from the contested Karish gas field. A textbook case of coercive diplomacy, Hezbollah's maneuver was calculated and deliberate, which reflects the group's strategic expertise. Drawing on open-source materials and public statements in Arabic and Hebrew, this article analyzes Hezbollah's coercive-diplomacy campaign and examines its implications for escalation scenarios between Israel and its central military opponent.  相似文献

Despite advances in research‐informed public policy, research remains underutilized in government. To develop a firmer understanding of governmental capacity to use research in decision making, we investigate Canadian provincial ministries overseeing education, higher education, and science and technology. The findings from semi‐structured interviews indicate that capacity to generate and access research is limited. However, we find evidence of a recent change in which provincial agencies sought to bolster capacity with research use strategies and by leveraging relationships with researchers. Leaders’ support for well‐coordinated research use initiatives also seems critical to instilling a culture of research‐informed decision making in government agencies.  相似文献

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.  相似文献
