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.     

The blood feud in Waziristan

Water puppetry has become an iconic representation of Vietnam, and Hanoi's Th?ng Long Water Puppet Theatre is flourishing as part of the international tourist package. This article documents the radical modification in this theatre's performance themes in 2013 – from traditional to explicitly ethnicised – and subsequent reversion the following year. In exploring the possible role of state propaganda in these changes, and the government's mechanisms of influence over water puppetry, the politics of representation within Vietnam's art and performance sector are exposed.     

Gender constructions and gender relations in cotton and chain-making in England: a contested and varied terrain

Abstract

While scholars have emphasised the positioning of women as wives and mothers in working-class culture in late nineteenth-century England, their position in the workforce remained significant, even in such disparate industries as cotton and chain-making. In the former, while excluded from spinning, women's employment in powerloom weaving brought them into the heart of the production process, encouraging their participation in workplace struggles and ultimately influencing a transformation in the working-class family in terms of fertility control. In chain-making, while some male workers attempted to position women in the domestic sphere, others were dependent on their labour. Cultural constructions of gender were thus undermined, as the struggle for the minimum wage superseded attempts to remove women from the workforce. In neither industry was equality between men and women realised, while antagonism on the basis of gender persisted. Yet women's identification with their work remained evident while mutuality across gender lines was also apparent, as women themselves played an active role in the shaping of gender relations. Conceptions of gender, as they intersected with particular labour market structures, thus came under duress. Consequently, a more complex picture of gender in working-class life emerges than an analysis which privileges cultural constructions would allow.     

Associations between national gambling policies and disordered gambling prevalence rates within Europe

Policymakers and other interested stakeholders currently are seeking information about the comparative effectiveness of different regulatory approaches to minimising gambling-related harm. This study responds to this research gap by exploring associations between gambling policies and disordered gambling prevalence rates. We gathered information about gambling policies for thirty European jurisdictions and past-year prevalence rates for disordered gambling for twelve of these jurisdictions. We present policy trends and prevalence rates and then describe the level of association between policy and prevalence. We observe one statistically significant association between policy and prevalence: rates of sub-clinical (i.e., Level 2) disordered gambling were higher within environments that mandated less strict regulation of advertising for online gambling. Finally, we discuss the implications of our research in the context of the current process regarding the pan-European regulation of gambling. Our findings do not offer evidence for certain assumptions made in the past by the European judiciary.     

Preparedness and crisis-driven policy change: COVID-19, digital readiness,and information technology professionals in Canadian local government

This article explores the pandemic-induced transition to electronic municipal council meetings in Ontario, Canada as an instance of crisis-driven policy change. Employing survey data of information technology (IT) professionals and a critical case study, this research probes the notion that crises, like pandemics, can not only create windows for policy change, but also draw attention to the many often overlooked operational elements of government, including the increasingly important policy role played by IT professionals.
