How intergroup friendship works: A longitudinal study of friendship effects on outgroup attitudes

Cross-sectional research has shown that frequency of self-disclosure to outgroup members mediates the positive relationship between intergroup friendship and outgroup attitudes. The current research investigated the relationship between self-disclosure and attitudes in more depth. New undergraduate students were asked to nominate an ingroup or outgroup friend and then report the intimacy of their disclosures to them, their anxiety and attitudes towards a series of social groups, in the first week of the semester and 6 weeks later. Intimacy of disclosure predicted more positive attitudes towards outgroups over time, but this association was only found among participants who nominated an outgroup friend. In the ingroup friend condition, a negative association was found. These associations were mediated by general intergroup anxiety. These relationships highlight the importance of integrating theories of interpersonal and intergroup relations when investigating intergroup contact. Copyright (C) 2011 John Wiley & Sons, Ltd.

Energy balance of SRC willow used for managing farmyard washings - how does it compare to a conventional wastewater treatment works?

The water and wastewater industry in the UK accounts for around 3% of total energy use and just over 1% of total UK greenhouse gas emissions. Targets for greenhouse gas emissions reduction and higher renewable energy penetration, coupled with rising energy costs, growing demand for wastewater services and tightening EU water quality requirements, have led to an increased interest in alternative wastewater treatment methods. The use of short rotation coppice (SRC) willow for the treatment of wastewater effluent is one such alternative, which brings with it the dual benefits of wastewater treatment and production of biomass for energy. In order to assess the effectiveness of SRC willow, it is important to analyse the overall energy balance in terms of energy input versus energy output. This paper carries out an energy life cycle analysis of a specific SRC willow plantation in Northern Ireland to which farmyard washings (dirty water) are applied. The system boundaries include the establishment, maintenance, and harvesting of the plantation, along with the transport and drying of the wood for biomass combustion. The analysis shows that the overall energy balance is positive, and that the direct and indirect energy demands are 12% and 8% of gross energy production respectively. The energy demands of the plantation are compared with the energy required to treat an equivalent nutrient load in a conventional wastewater treatment plant. While a conventional plant consumes 2.6 MJ/m3 , the irrigation system consumes 1.6 MJ/m3 and the net energy production of the scenario is 48 MJ/m3 .

The Political Economy of Swift's Satires and other Prose Works

Jonathan Swift wrote perceptively about the emerging commercial society
in Britain in the early eighteenth century. His particular focus was on the
financial revolution and its implications for economic and political stability
as well as for shifts of power between the landed and commercial
classes. Following his return to Ireland Swift’s focus shifted to the developmental
problems of his native country. In several pamphlets he advocated
consumption of domestic products, challenged existing political
structures and made trenchant criticisms of absenteeism and other dysfunctional
aspects of the land tenure system. Swift’s politico-economic
concerns are fully reflected in his best known work, Gulliver’s Travels but
his most pointed criticism of the emerging commercial system is contained
in A Modest Proposal. Written in the form of an economic pamphlet, A
Modest Proposal is ostensibly designed to address the problem of poverty
in Ireland. In addition to its implicit criticism of economic policy in Ireland,
the pamphlet challenges the separation of economics and morality as
evidenced in the writings of William Petty and Bernard Mandeville. Swift
parodies Petty’s political arithmetic but it is suggested here that he also
had in his sights the consequentialist reasoning present in the work of
both authors but explicitly so in Mandeville.

Listening to the World Through New Ears:Reinvention of the soundtrack in the works of Lucrecia Martel and Sofia Coppola

This paper explores the production and post-production techniques and tensions in designing sound for film. Considering the films of Lucrecia Martel and Sofia Coppola, amongst others, Greene and Yang will discuss how the soundtrack takes on a primary role in these films and becomes a medium for symbolism, reflection, characterisation, as well as storytelling. There will be a close examination of the processes involved in creating character-orientated soundscapes. These processes are sensitive to the effects sound has on an audience. Exploring how these filmmakers (with their sound teams) utilise the listening experience, including attention to point of audition and sound perception, this paper will critically unpick how such creative decisions are arrived at during various stages of the production process. Outlining the use of diegetic and non-diegetic sound and the potential musicality of sound effect design, issues of reverberation, noise and intent are discussed to highlight the sonic framing of these creative teams. Greene will approach these soundtracks from a production/post-production perspective, while Yang will explore the composer’s/designer’s ear.
