The analytical determination of friction for flow through conical converging dies

The effects of friction upon the intermediate and final distorted grids for wire drawing and/or extrusion were analytically studied for an assumed triangular velocity field. An upper-bound solution for the process was used. This solution predicted that the shape of the final and intermediate distorted grids were functions of the process geometry and of friction. Initially, combinations of reduction and semi-cone angle (α) were found for which the triangular velocity field was energetically preferred over an existing spherical velocity field. The analytical final distorted grids were then compared to experimentally obtained final distorted grids to determine the experimental friction. This was done by plotting calibration curves for distortion where friction served as the parameter and by comparing the actual distortion with the family of calibration curves.     

Cross-Cultural Perspectives on Intercultural Communication Competence

This study examined the process of developing intercultural communication competence (ICC) with particular attention to cross-cultural differences in communication patterns. A qualitative approach involving 40 interviews with Americans living in Sweden and Swedes living in the US was employed in order to gain a nuanced, in-depth, and contextual understanding of how immigrants and expatriates experience the process. Several differences in verbal and nonverbal communication patterns between the two cultures emerged. The findings provide insights into how ICC is developed differently across cultures, as well as how the cognitive, affective, and behavioral components of ICC are interrelated and influenced by culture-specific aspects.     

‘Who cares?’ Gender,care and secondary schooling: ‘Accidental findings’ from a seclusion unit

A breadth of research explores gendered professional identities, practices and spaces across a range of UK educational institutions. One focus has been on links between gender, care and education in early years settings and primary schools, although less attention has been given to caring within secondary schools. Drawing on qualitative research conducted in London within an in-school seclusion unit, this article brings together a Lefebvrian conceptualisation of space with feminist theorisations of care to explore how the unit (conceived as a space of control, discipline and punishment) also became an unlikely space of care. In doing so, the article explores complex intersections between gender and care and how everyday caring practices in schools are inextricably linked to and embedded within broader institutional and spatial agendas and processes.     

Transforming schools: illusion or reality?1

This paper explores the claim that appropriately trained heads can motivate teachers and students to achieve challenging targets and transform the prospects of future generations. Theory derived from the leadership literature is tested against the experience of three headteachers in the field. Case study evidence is used to examine how Hillside School was improved. Applying recommended styles, the heads won the commitment of their colleagues and built the capacity for further progress, despite adverse circumstances that included social disadvantage. Although the ‘turn around’ was achieved quickly, the interpersonal styles adopted by the heads were only part of a leadership repertoire that included beliefs, values, professional knowledge and micro-politics. Variations in the combination of context, leaders and followers seem to have been more significant than the common elements emphasized by the school improvement literature and national training programmes. OfSTED reported that the school's effectiveness was greatly enhanced. Test and examination results were more or less unchanged, however, confirming recent studies that have found little evidence of leadership impact on student outcomes. This supports the suggestion that intake mix may influence results more than the organizational characteristics shaped by heads. The paper concludes that while leadership training may improve school climate, a transformation in performance is unlikely.     

How girls and boys expect disclosure about problems will make them feel: implications for friendships

Although girls disclose to friends about problems more than boys, little is known about processes underlying this sex difference. Four studies (Ns = 526, 567, 769, 154) tested whether middle childhood to mid-adolescent girls and boys (ranging from 8 to 17 years old) differ in how they expect that talking about problems would make them feel. Girls endorsed positive expectations (e.g., expecting to feel cared for, understood) more strongly than boys. Despite common perceptions, boys did not endorse negative expectations such as feeling embarrassed or worried about being made fun of more than girls. Instead, boys were more likely than girls to expect to feel "weird" and like they were wasting time. Sex differences in outcome expectations did help to account for girls' greater disclosure to friends.     

The development and preliminary assessment of a set of video‐taped informative speech models

Guidelines are specified in this article for developing video‐taped informative speech models. Faculty members rated selected video‐taped informative speeches on nine variables and two months later rated nine of the same speeches again. The faculty judges were reliable on their ratings for eight of the nine variables rated during the two sessions. Five of the nine speeches were identified as being representative of one of three significantly different levels of excellence.
