When chivalry backfires: Benevolent sexism and attitudes toward Myra Hindley

Researchers have suggested that paternalistic attitudes may influence people's perceptions of female offenders. In the current study, we examined the role of benevolent and hostile sexism in people's perceptions of a specific female offender (Myra Hindley), who can be viewed as having violated traditional gender role assumptions. We observed that benevolent sexism (but not hostile sexism) was related to negative evaluations of Myra Hindley. In addition, mediation analyses suggest that the relationship between benevolent sexism and the negative evaluations of Myra Hindley was partially accounted for by participants' perceptions that Myra Hindley possessed traits that violated traditional gender role stereotypes. Theoretical and practical implications are discussed.

Technical and economic factors in applying the enhanced coalbed methane recovery process

Geological sequestration of CO2 is a technically feasible and potentially economic option for significantly and safely reducing greenhouse gas emissions, with CO2 injection already practiced in Canada and the USA to enhance crude oil production. The Enhanced Coalbed Methane (ECBM) process is seen as the next most economical sequestration options. The authors estimate an incremental methane recovery factor from 20% to 50%, depending on coal rank and seam depth. Others have estimated the potential to increase worldwide CBM production, utilising ECBM, by 18 Trillion cubic meters, while simultaneously sequestering 345 Giga tonnes of CO2. This paper presents technical and economic factors to consider for developing a commercial ECBM project. Technical factors include: geostructural and hydrogeological issues, geochemical reactions, stressed and competitive sorption, counter-diffusion, effective and relative 4-D coal permeability and methane recovery levels. Key economic factors are injectant acquisition price, sale price of methane and the level of carbon credits.
