Effect of evaporation and matrix interferences on the association of simulated ignitable liquid residues to the corresponding liquid standard

Identification of an ignitable liquid in fire debris evidence can be complicated due to evaporation of the liquid, matrix interferences, and thermal degradation of both the liquid and the matrix. In this research, liquids extracted from simulated fire debris were compared to the original liquid using multivariate statistical procedures. Neat and evaporated gasoline and kerosene standards were spiked onto nylon carpet, which was subsequently burned. The ignitable liquid residues were extracted using a passive headspace procedure and analyzed by gas chromatography-mass spectrometry. Pearson product moment correlation coefficients, hierarchical cluster analysis, and principal components analysis were used to compare the liquids extracted from the carpet to the corresponding neat liquid. For each procedure, association of the extracts according to liquid type was possible, albeit not necessarily to the specific evaporation level. Of the three procedures investigated, principal components analysis offered the most promise since contributions from matrix interferences were essentially eliminated.     

Colonization of diatoms in and on porcine bone substrate and considerations of diatom ecology for forensic science

The presence of diatom algae in bone marrow has been used as forensic evidence of drowning for several decades; however, these studies are based on known or suspected recent drowning events. This study addresses the potential for diatoms to enter the bone marrow of skeletal remains, that is, de-fleshed long bones post-mortem. In laboratory and field experiments, bones were either inflicted with two access points by a cut and acid pitting or left intact. The bones were submerged in water for at least 1 week and up to 3 months. Samples of the bone surface and marrow were inspected for diatoms. The analysis considered the time required for diatoms to enter marrow and whether genus characteristics like size or mobility affect entry. The presence of an access point influenced diatom entry in that bones without an introduced access point had zero to one diatom present in the marrow, whereas a bone with an access point had >150 diatoms present in the marrow. The results of both laboratory and field phases suggest that diatoms will reliably colonize bone in as quickly as 1 week, establishing and maintaining communities for at least 3 months. However, the bone surface assemblages differ from the source community. Bone marrow displayed even more restrictive access to diatom colonization, resulting in communities dominated by small raphid diatoms. Based on these findings, we suggest some caveats on the use of diatoms as trace evidence in forensic science with recommendations for future avenues of research.     

Exemption: A Gendered History

Diverse questions might be contemplated once we consider the gender implications and impacts of Aboriginal exemption policies. The article traces such questions in relation to a series of distinct episodes in the history of exemption. The first of these focuses on postwar New South Wales, where marital status was core to the application process from the point of its introduction, and the system built upon older policies of ‘training’ Aboriginal girls as servants. The second moment, moving back in time, discusses a petition for collective exemption for a group of women domestic workers in Broome, Western Australia, that was presented to a government enquiry in 1934. The third concerns the quest for release from government controls by several domestic workers brought to Adelaide in South Australia, from the Northern Territory, in the late 1920s. Finally, the article reflects upon the efforts of young women placed in service in early-twentieth-century Brisbane, Queensland, to secure exemptions, and the responses of the authorities. While exemption policies may have been designed to impose Anglo-Australian gender norms of female dependence, Aboriginal women who worked in service consistently subverted these aims, by using the discourses of domesticity to challenge and resist the authorities' power.     

The Albanian Diaspora and security in the Balkans

The main theses of this article, completed on the eve of the NATO bombing campaign, remain relevant. With half of Europe's Muslim Albanians living outside Albania proper in Slavic and Greek Orthodox countries, the resultant risk of a broader Balkan conflict remains. Indeed, the sense of grievance of both Serbs and Albanians has been intensified by ethnic cleansing, bombing, dispossession, and polarization. Those like Kosovar shadow President Rugova, who were committed to multi‐ethnic compromise, have been pushed aside by the KLA. Increasingly, the long‐term solution in Kosovo appears to be one of independence from both Serbia and Albania with the rights of Serbs preserved by partition policed by NATO/UN forces.     

The effect of logistic services on the watermelon value chain in Tanzania

This article reports on a study that aimed to understand the effects for poverty reduction of the link between logistic services and cost of the watermelon value chain in Rufiji and Mkuranga districts in Tanzania. Structured questionnaires and FGDs were used to collect data from 251 respondents. Findings revealed that transport cost, storage cost, purchase cost, and logistics service have strong significant effect on the watermelon value chain cost. Based on the findings, the study recommended the use of affordable methods of storage, opening agro-input shops in villages, and the development of a favourable environment for watermelon businesses, to help reduce chain cost.     

The Illusion of Resistance: Commodification and Reification of Neoliberalism and the State

While protests and acts of resistance are central to democracy and the potential for social change, what is often ignored is the usurping of resistance through commodification and consumption. Here we argue that it is important to remember that even acts of resistance, such as we have witnessed since the election of Donald Trump to the Presidency of the United States, that speak out against inequality and social harm are commodified and consumed within the spectacular domination of the State and capital, making resistance part and parcel of the neoliberal system that commoditizes in totality.     

The power of small-scale solar: gender,energy poverty,and entrepreneurship in Tanzania

Energy poverty is a major challenge in the developing world, with an estimated 1.2 billion people lacking household electricity. Although energy poverty affects both men and women, the burden of household energy supply disproportionately affects women in low-income countries in the developing world. This article examines the impact of a women-oriented solar lighting social enterprise, Solar Sister, in Tanzania for both solar entrepreneurs and customers, demonstrating that solar lanterns positively impact household savings, health, education and women’s economic productivity and empowerment. Our study argues that Solar Sister’s approach is successful because of its explicit gender lens. Providing energy access to women translates to a pro-woman, pro-child, and pro-family development intervention.     

Setting aside a trust on the ground of mistake--In the Matter of the DSL Remuneration Trust: DSL Remuneration Trust [2007] JRC 251

This case concerned a remuneration trust which had been establishedby a company called DSL in April 2000. The beneficiaries ofthe Trust were named as the past, present and future employeesof DSL and their families. The shares in DSL were owned by acouple, Mr and Mrs L, who were also the two directors of DSL.The Trust assets comprised the proceeds of sale of the businessof DSL and its interest in two retail shops, and representedthe bulk of the assets of Mr and Mrs L and their family. The terms of the Trust prevented any outright distribution orpayments being made or any benefits
