The present research addresses how voters’ perceptions of Hillary Clinton’s warmth and competence influenced decisions to vote for her in the 2008 Democratic primary. We apply research on gender stereotypes and perceptions of women leaders to demonstrate that voters perceived Clinton as highly competent but relatively less warm. Further, this research examines how perceptions of Clinton’s warmth and competence contributed to decisions to vote for her. Results suggest that perceptions of Clinton’s warmth and competence differentially predicted voting behavior for voters strongly and less strongly identified with their political party. This research provides a descriptive analysis of how voters’ beliefs about leaders can be colored by gender, and how such beliefs contribute to electing women candidates.

This article offers an examination of the interplay between politics, ethics, theory and methodology as they impact upon social research, through a critical analysis of the ethnographic study conducted by Peter Foster. It will be argued that his highly contentious claim to have found no manifestations of racism (either direct or indirect) throughout his study of an inner-city, multi-ethnic comprehensive school was, in the last analysis, both misleading and inaccurate. It will be contended that such claims were based upon a research design and methodology which were ultimately determined by his own political orientation and the ethical and theoretical positions which he developed as a consequence.

The early-age strength development of concrete containing slag cement has been investigated to give guidance for its use in fast-track construction. Measurements of temperature rise under adiabatic conditions have shown that high levels of slag cement-for example, 70% of the total binder-are required to obtain a significant reduction in the peak temperature rise. Despite these temperature rises being lower than those for portland cement mixtures, however the early-age strength under adiabatic conditions of slag cement concrete can be as high as 250% of the strength of companion cubes cured at 20 degrees C (68 degrees F). The maturity and, hence, strength development were calculated from the adiabatic temperature histories based on several Maturity functions available in the literature. The predicted strength development with age was compared with the experimental results. Maturity functions that take into account the lower ultimate strengths obtained at elevated curing temperatures were found to be better at predicting the strength development.
