Food provisioning experiences of ultra poor female heads of household living in Bangladesh

Ultra poor women in Bangladesh are especially vulnerable to poverty and food insecurity, and they have generally been excluded from recent improvements in hunger and poverty rates in the country. An examination of the food provisioning narratives of 43 ultra poor female heads of household in Bangladesh was conducted in order to deepen understanding of this obstacle to the country's achievement of the First Millennium Development Goal. All participants were the household's sole income provider, had dependent children, and earned less than $1 USD per day. Women were purposively selected based on occupational group, context, and personal characteristics. Ethnographic interviews were conducted in January and February, 2008. Analysis of women's accounts of their daily food routine revealed chronic and pervasive food insecurity punctuated by acute episodes of absolute food deprivation that resulted from seasonal fluctuations in earnings, rising food prices, illness disrupting work, and healthcare costs. Women's accounts of their daily food provisioning experiences suggested compromises in, and trade-offs between, multiple basic needs as a result of inadequate income. Women were further constrained by social norms and gender roles that influenced their ability to work outside the home. Our method of inquiry led us to construct an organizing framework that extends knowledge of ultra poor women in Bangladesh's complex and multi-sphered experience of poverty and food insecurity. Based on these findings, we propose a strategy called whole person development (WPD), which seeks small adjustments to services, programs, and policies based on leverage points identified through in-depth narratives.Bangladesh Food provisioning Food insecurity Women Head of household Ultra poor Millennium development goals Whole person development Poverty

The Common Sunstar <i>Crossaster papposus</i>—A Neurotoxic Starfish

Saxitoxins (STXs) are a family of potent neurotoxins produced naturally by certain species of phytoplankton and cyanobacteria which are extremely toxic to mammalian nervous systems. The accumulation of STXs in bivalve molluscs can significantly impact animal and human health. Recent work conducted in the North Sea highlighted the widespread presence of various saxitoxins in a range of benthic organisms, with the common sunstar (Crossaster papposus) demonstrating high concentrations of saxitoxins. In this study, an extensive sampling program was undertaken across multiple seas surrounding the UK, with 146 starfish and 5 brittlestars of multiple species analysed for STXs. All the common sunstars analysed (n > 70) contained quantifiable levels of STXs, with the total concentrations ranging from 99 to 11,245 µg STX eq/kg. The common sunstars were statistically different in terms of toxin loading to all the other starfish species tested. Two distinct toxic profiles were observed in sunstars, a decarbomylsaxitoxin (dcSTX)-dominant profile which encompassed samples from most of the UK coast and an STX and gonyautoxin2 (GTX2) profile from the North Yorkshire coast of England. Compartmentalisation studies demonstrated that the female gonads exhibited the highest toxin concentrations of all the individual organs tested, with concentrations >40,000 µg STX eq/kg in one sample. All the sunstars, male or female, exhibited the presence of STXs in the skin, digestive glands and gonads. This study highlights that the common sunstar ubiquitously contains STXs, independent of the geographical location around the UK and often at concentrations many times higher than the current regulatory limits for STXs in molluscs; therefore, the common sunstar should be considered toxic hereafter

Comparison of AOAC 2005.06 LC official method with other methodologies for the quantitation of paralytic shellfish poisoning toxins in UK shellfish species

A refined version of the pre-column oxidation liquid chromatography with fluorescence detection (ox-LC-FLD) official method AOAC 2005.06 was developed in the UK and validated for the determination of paralytic shellfish poisoning toxins in UK shellfish. Analysis was undertaken here for the comparison of PSP toxicities determined using the LC method for a range of UK bivalve shellfish species against the official European reference method, the PSP mouse bioassay (MBA, AOAC 959.08). Comparative results indicated a good correlation in results for some species (mussels, cockles and clams) but a poor correlation for two species of oysters (Pacific oysters and native oysters), where the LC results in terms of total saxitoxin equivalents were found to be on average more than double the values determined by MBA. With the potential for either LC over-estimation or MBA under-estimation, additional oyster and mussel samples were analysed using MBA and ox-LC-FLD together with further analytical and functional methodologies: a post-column oxidation LC method (LC-ox-FLD), an electrophysiological assay and hydrophilic interaction liquid chromatography with tandem mass spectrometric detection. Results highlighted a good correlation among non-bioassay results, indicating a likely cause of difference was the under-estimation in the MBA, rather than an over-estimation in the LC results.

The neighbourhood context of urban Aboriginal crime

This article addresses Carol La Prairie's (1992; 2002) hypothesis that the over-representation of Aboriginal people in the Canadian criminal justice system is, to a considerable extent, due to their disadvantaged urban living conditions. Specifically, it investigates the sources of the high level of policereported Aboriginal crime in Winnipeg in 2001. Geocoded crime incident data from the incident-based Uniform Crime Reporting Survey and Census data for the City of Winnipeg are combined in a neighbourhood-level ecological analysis of urban Aboriginal crime. The results indicate that a substantial part of the elevated level of police-reported Aboriginal crime is explained by the structural characteristics of the neighbourhoods in which Aboriginal people tend to live. These results confirm La Prairie's hypothesis and point to the importance of considering community conditions in understanding and preventing crime
