Crossing the Border: Locating Heterosexuality as a Boundary for Lesbian Women and Disabled Women

NoThis article draws on my personal experience, and on the separate experiences of 'leaving heterosexuality' and of 'being disabled'. I have attempted to find common ground for action between these two groups by interrogating the experience of being sexual. I argue that heterosexuality functions as a social matrix, with exclusionary practices that operate in similar ways towards both groups. Mechanisms may be different, but the experience of exclusion is similar, and is based on similar practices. This article focuses on specific points in the exclusionary process, and illustrates similarities

Mineral resource maps and safeguarding areas : a Welsh case study

Access to economic mineral resources in the UK, such as sand and gravel and crushed rock aggregate, is vital to ensure the continued supply of raw materials that are essential for maintaining national infrastructure and underpinning the economy. Increasing pressures on land use threaten adequate mineral supply in the long term if the location of mineral resources is not considered when siting other types of development. Security of supply of minerals is, therefore, becoming an increasing priority for local and national government organisations responsible for planning for development

Improving the attention students pay to, and the extent to which they act upon feedback.

Report of a CELT project on supporting students through innovation and researchThat learning is a cyclical process and that assessment drives learning are established facts. It is essential that an assessment regime considers not only what a student should know but also their approach to their learning. If students are required to evaluate, for instance, the ethical implications of IT, then it is not appropriate to use an assessment instrument that simply asks for regurgitation of information. In order to improve future performances, feedback on work presented by a knowledgeable other person, whether tutor, placement supervisor or peer, is essential.2 Staff perceive that feedback prompts student discussion of their work, enables understanding and improves learning. The aims of this project were to improve the efficacy of the feedback process and the quality of assessment feedback in the School of Computing and Information Technology (SCIT). This was through the implementation of a range of steps, based on those proposed by Gibbs during the University of Wolverhampton Campaign on Assessment 2002/03)

Conversion of laser energy to chemical energy by the photoassisted electrolysis of water

Ultraviolet irradiation of the n-type semiconductor TiO2 crystal electrode of an aqueous electrochemical cell evolves O2 at the TiO2 electrode and H2 at the Pt electrode. The gases are typically evolved in a 2:1 (H2:O2) volume ratio. The photoassisted reaction seems to require applied voltages, but values as low as 0.25 V do allow the photoassisted electrolysis to proceed. Prolonged irradiation in either acid or base evolves the gaseous products in amounts which clearly demonstrate that the reaction is catalytic with respect to the TiO2. The wavelength response of the TiO2 and the correlation of product yield and current are reported. The results support the claim that TiO2 is a true photoassistance agent for the electrolysis of water. Minimum optical storage efficiencies of the order of 1 percent can be achieved by the production of H2

Kinetic Theory for Electron Dynamics Near a Positive Ion

A theoretical description of time correlation functions for electron properties in the presence of a positive ion of charge number Z is given. The simplest case of an electron gas distorted by a single ion is considered. A semi-classical representation with a regularized electron - ion potential is used to obtain a linear kinetic theory that is asymptotically exact at short times. This Markovian approximation includes all initial (equilibrium) electron - electron and electron - ion correlations through renormalized pair potentials. The kinetic theory is solved in terms of single particle trajectories of the electron - ion potential and a dielectric function for the inhomogeneous electron gas. The results are illustrated by a calculation of the autocorrelation function for the electron field at the ion. The dependence on charge number Z is shown to be dominated by the bound states of the effective electron - ion potential. On this basis, a very simple practical representation of the trajectories is proposed and shown to be accurate over a wide range including strong electron - ion coupling. This simple representation is then used for a brief analysis of the dielectric function for the inhomogeneous electron gas.Comment: 30 pages, 5 figures, submitted to Journal of Statistical Mechanics: Theory and Experimen

Deactivation of biacetyl triplets by cyanocobaltate(III) complexes

The rate of electronic energy transfer from biacetyl triplets to Co(CN)_(5)(X)^(n–)(X = CN^–, MeCN, pyridine, N_(3)^–, H_(2)O, or SCN^–) is strongly dependent on the energy of the first spin-allowed d–d transition of Co(CN)_(5)(X)^(n–), and (for X = CN^–, N_(3)^–, and SCN^–) the direct and sensitized photosubstitution yields are the same, implying a common reactive state
