Diary of a participatory advocacy film project: transforming communication initiatives into living campaigns

In August 2007, the government of Tanzania made a commitment to doubling the number of training places for skilled midwives, following a five-year campaign by the White Ribbon Alliance for Safe Motherhood in Tanzania (WRATZ), which culminated in the first television screening of a participatory film, ‘Play Your Part’. With contributions from a range of health professionals, communities, a pop singer, and the Minister of Health, the message was that everyone at every level has a part to play in saving mothers' lives. WRATZ was successful because it was able to promote its message in a way that provides a model for advocacy, combining the reactive creativity of journalism and the methodological rigour of participatory video to bring about a tangible impact.     

A Rare Case of Poisoning with a Volatile Substance: Quantitative Determination of n‐Butane in Postmortem Tissue

Poisoning with volatile substances remains exceptional. Authors report the case of a married couple who were found in a car with a butane gas bottle: the woman was dead and her husband alleged it was an unsuccessful suicide pact. A specific research of volatile substances on postmortem samples with headspace gas chromatography–mass spectrometry following a quantitative determination was performed. The n‐butane concentrations detected were composed of 610 μg/L (cardiac blood), 50 μg/kg (brain), 134 μg/kg (lungs), 285 μg/kg (liver), and 4090 μg/kg (heart) and were compatible with the rare lethal concentrations evoked in the literature. The cause of death was determined to be asphyxiation through n‐butane criminal poisoning. Authors recommendation therefore is to take samples immediately and place them in properly sealed containers and hence analyzing the samples as soon as possible after collecting them or storing them under ?30°C (?22°F) if analyses cannot be performed immediately.     

Exogenous Lipoid Pneumonia as a Contributory Factor in a Drug‐related Death

Postmortem investigation often reveals various conditions, which may or may not have played a part in the death of the individual. The case of a 32‐year‐old woman is reported, with a long history of drug addiction. She was found dead in her bed. The autopsy revealed diffuse pulmonary edema with congestion of the lungs, brain, liver, and spleen. Microscopic examination of the lungs showed multiple intra‐alveolar and interstitial foamy macrophages and extracellular fat droplets surrounded by polynuclear giant cells. Death was attributed to acute polydrug intoxication. As microscopic examination had revealed severe pulmonary lesions, lipoid pneumonia was considered as a contributing factor to death. Lipoid pneumonia is an uncommon entity with the characteristic radiograph features and histologic findings of alveoli filled with vacuolated, lipid‐laden histiocytes. It can be either exogenous or endogenous in cause, based on the source of the lipid. Exogenous lipoid pneumonia usually results from aspiration or inhalation of fat‐like material, such as mineral oil or petroleum‐based lubricants and decongestants, resulting in pulmonary inflammatory reactions.     

A new approach to measuring technology with an application to the shape of the diffusion curves

This paper documents the sources and measures of the cross-country historical adoption technology (CHAT) data set that covers the diffusion of about 115 technologies in over 150 countries over the last 200 years. We use this comprehensive data set to explore the shape of the diffusion curves. Our main finding is that, once the intensive margin is measured, technologies do not diffuse in a logistic way.

How Strong is the Evidence for the Existence of Poverty Traps? A Multicountry Assessment

Introducing this special collection on asset dynamics and poverty traps, this article assesses evidence on these issues across eight panel data sets in six countries generally not previously considered in this perspective. It examines the importance of assets in relation to chronic poverty and uses parametric and non-parametric methods to test for dynamic asset-based poverty traps. The article finds that chronically poor households have lower levels of assets than others, though does not find evidence of the non-convexities which would imply a multiple dynamic poverty trap. From this base the article introduces the remainder of the articles in this collection which set out many promising approaches to further develop and improve methods and approaches for looking at poverty traps in future.
