Measurements of nonmethane hydrocarbons in 28 United States cities
Between 1999 and 2005 a sampling campaign was conducted to identify and quantify the major species of atmospheric nonmethane hydrocarbons (NMHCs) in United States cities. Whole air canister samples were collected in 28 cities and analyzed for methane, carbon monoxide (CO) and NMHCs. Ambient mixing ratios exhibited high inter- and intra-city variability, often having standard deviations in excess of 50% of the mean value. For this reason, ratios of individual NMHC to CO, a combustion tracer, were examined to facilitate comparison between cities. Ratios were taken from correlation plots between the species of interest and CO, and most NMHCs were found to have correlation coefficients (r2) greater than 0.6, particularly ethene, ethyne and benzene, highlighting the influence of vehicular emissions on NMHC mixing ratios. Notable exceptions were the short-chain alkanes, which generally had poor correlations with CO. Ratios of NMHC vs. CO were also used to identify those cities with unique NMHC sources. © 2007 Elsevier Ltd. All rights reserved
Can rights stop the wrongs? Exploring the connections between framings of sex workersâ rights and sexual and reproductive health
<p>Abstract</p> <p>Background</p> <p>There is growing interest in the ways in which legal and human rights issues related to sex work affect sex workersâ vulnerability to HIV and abuses including human trafficking and sexual exploitation. International agencies, such as UNAIDS, have called for decriminalisation of sex work because the delivery of sexual and reproductive health services is affected by criminalisation and social exclusion as experienced by sex workers. The paper reflects on the connections in various actorsâ framings between sex workers sexual and reproductive health and rights (SRHR) and the ways that international law is interpreted in policing and regulatory practices.</p> <p>Methods</p> <p>The literature review that informs this paper was carried out by the authors in the course of their work within the Paulo Longo Research Initiative. The review covered academic and grey literature such as resources generated by sex worker rights activists, UN policy positions and print and online media. The argument in this paper has been developed reflectively through long term involvement with key actors in the field of sex workersâ rights.</p> <p>Results</p> <p>International legislation characterises sex work in various ways which do not always accord with moves toward decriminalisation. Law, policy and regulation at national level and law enforcement vary between settings. The demands of sex worker rights activists do relate to sexual and reproductive health but they place greater emphasis on efforts to remove the structural barriers that limit sex workersâ ability to participate in society on an equal footing with other citizens.</p> <p>Discussion and conclusion</p> <p>There is a tension between those who wish to uphold the rights of sex workers in order to reduce vulnerability to ill-health and those who insist that sex work is itself a violation of rights. This is reflected in contemporary narratives about sex workersâ rights and the ways in which different actors interpret human rights law. The creation of regulatory frameworks around sex work that support health, safety and freedom from abuse requires a better understanding of the broad scope of laws, policies and enforcement practices in different cultural contexts and economic settings, alongside reviews of UN policies and human rights conventions.</p

The re-emergence of âtraffickingâ: sex work between slavery and freedom
Activists find that sex work is considered a less legitimate occupation today than it was in the 1980s
and early 1990s. They now confront representations of sex workers as victims, sold and bought
across national borders and reduced to the status of things. In this climate, labour rights seem
irrelevant. Recent shifts in the language of consent and compulsion in the UK are explored in the
light of historical parallels in order to suggest a general ambivalence towards all forms of work. Is it
possible to experience freedom or only subjugation at work? What is the role of gender in
differentiating these polar opposites
