Postdiscrimination generalization as a function of interresponse time

Following 20 sessions of variable-interval 20-sec reinforcement in the presence of a single 45-deg line-tilt stimulus, three pigeons were trained to discriminate between line tilts of 45 deg correlated with variable-interval 20-sec reinforcement and line tilts of 15 deg correlated with extinction. A generalization test along the line-tilt dimension was administered following a criterion discrimination performance. Gradients derived in terms of relative frequency of response as a function of line tilt indicated strong external stimulus control and exhibited clear peak shift. From the interresponse time (IRT) distributions generated for responding to each test stimulus, probability of response conditional upon IRT (IRTs/Op) was derived as a joint function of line tilt and IRT. The IRTs/Op functions for responses following IRTs in 0.2-sec-wide classes from 0.2 to 1.0 sec and for responses following IRTs in the interval of 1.0 to 2.0 sec were similar to the relative generalization gradients and also exhibited peak shift. Few IRTs were greater than 2.0 sec. External stimulus control was established over responses terminating IRTs both longer and shorter than 1.0 sec.     

The Gendered Shaping of University Leadership in Australia,South Africa and the United Kingdom

This article analyses career trajectories into university management in Australia, South Africa and the United Kingdom (UK), skills required to operate effectively and the power of vice‐chancellors (VCs) and their impact on the gendered shaping of university leadership. It is based on qualitative research with 56 male and female senior managers. The research found that the typical career path was modelled on male academic careers. Not surprisingly, in South Africa and the UK the perception of the top university leader was of a man but in Australia, where more women have been VCs, there was no such assumption. Characteristics valued in university leaders in Australia and South Africa were ‘soft’ leadership traits, but in the UK ‘hard’ aggressive and competitive leadership prevailed. VCs are enormously powerful and can shape the gender balance in management teams and thereby potentially broadening leadership styles beyond the predominant transactional model to include transformational leadership.     

Mothers who are student teachers: navigating their dual roles in pre-service teacher education

Many students in New Zealand are now of mature age, female, and mothers of dependent children (Allister et al. 2006). These students typically experience the challenge of sharing themselves between their children, partners, extended families and their fellow students, lecturers and studying. This research explored how a group of student-teachers who were also mothers experienced these dual roles and sought to document their beliefs, motivations, attitudes to these roles from the time they had entered teacher education. The following key themes emerged from the in-depth interviews with the women: strong motivation for wanting to become primary school teachers; the impact this decision had on the lives of their children, partners and extended families; the particular issues they faced as they tried to navigate the roles of mother and student-teacher; and the suggestions they had for continuing education and tertiary institutions to improve opportunities for other mothers wanting to study. This last theme is perhaps the most pertinent, as it offers implications for continuing education institutions wanting to attract and retain these students, who, as a group, represent a growing demographic trend in the student population.     

Focus Group Effects on Field Practicum Preferences

ABSTRACT

During the coming years the need for professionals to work with the nation's elders will increase several fold. This will place a great responsibility on university educational programs to prepare enough qualified future professionals to work in the greatly expanding field of gerontology. Prior research has identified several nonacademic and academic experiences that influence a student's decision to become gerontological professionals. One area that has been omitted from this work concerns focus groups. This article reports on the impact that observing a relatively simple and inexpensive focus group of professional geriatric practitioners can have on field practicum preferences among advanced undergraduate social work students at a large Texas state university. Findings indicate that observing a focus group significantly influences students' practicum preferences for working with elders, thereby setting them on a trajectory for a career in geriatrics.     

Higher education emotions: a scale development exercise

Emotion experienced in the classroom has been shown to influence subject-level satisfaction and loyalty to the institution. To date, a valid and reliable scale to measure higher-education satisfaction emotions does not exist and this study aims to rectify this shortfall. After a qualitative and quantitative investigation, 14 emotions that formed three dimensions were retained. These emotions, when combined with performance perceptions, explained 71% of the variance in satisfaction with a learning and teaching experience that, in turn, explained 82% of the variance in loyalty to the institution. This scale can complement existing evaluation instruments and assist education managers and marketers in capturing a richer understanding of their students' experience, which, if managed correctly, can lead to enhanced reputation and increased future enrolments.
