Dilemmas in Framing Research Studies in Engineering Education

There has been considerable debate about the need for more empirical, evidence based studies of the impact of various interventions and practices in engineering education. A number of resources including workshops to guide engineering faculty in the conduct of such studies have emerged over recent years. This paper presents a critique of the evolution of engineering education research and its underlying assumptions in the context of the systemic reform currently underway in engineering education. This critique leads to an analysis of the ways in which our current understanding of engineering, engineering education and research in engineering education is shaped by the traditions and cultural characteristics of the profession and grounded, albeit implicitly, in a particular suite of epistemological assumptions. It is argued that the whole enterprise of engineering education needs to be radically reconceptualized. A pluralistic approach to framing scholarship in engineering education is then proposed based on the principles of demonstrable practicality, critical interdisciplinarity and holistic reflexivity. This new framework has implications for engaging and developing faculty in the context of new teaching and learning paradigms, for the evaluation of the scholarship of teaching and for the research-teaching nexus.

Going up? Women in the public sector

Abstract: Purpose – This paper aims to document women's reflections on their careers over a ten-year period to provide quantitative baseline data on which to frame follow-up in-depth interviews. The participants work in the public service in Queensland (Australia) and had been recommended for, and participated in, women in management (WIM) courses conducted in the early 1990s. Design/methodology/approach – Data were collected by means of a survey (containing closed and open items) which gathered demographic data and data related to employment history, perceptions of success and satisfaction, and the women's future career expectations. Findings – Findings revealed that the percentage of women in middle and senior management had increased over the ten-year period, although not to the extent one might have anticipated, given that the women had been targeted as high flyers by their supervisors. While not content with their classification levels (i.e. seniority), the majority of the cohort viewed their careers as being successful. Practical implications – Questions arise from this study as to why women are still “not getting to the top”. There are also policy implications for the public service concerning women's possible “reinventive contribution” and training implications associated with women only courses. Originality/value – The study is part of an Australian longitudinal study on the careers of women who attended a prestigious women-only management course in the early 1990s in Queensland. This is now becoming a study of older women.

Students' conceptions of sport and sport education

This article explores a class of Grade 5 (age 9 and 10) children’s conceptions of sport during a season of sport education at Forest Gate Primary School. The purpose, following Kirk and Kinchin (this issue), is to examine the extent to which the potential transfer of learning between school and sport as a community of practice may be possible through sport education in school physical education. With reference to student interviews and drawings we report and discuss children’s conceptions of sport, their experiences of sport outside of the school, and their emerging conceptions of sport education in light of these prior understanding and experiences. We conclude that there was an evident level of compatibility between students’ experiences of sport education and their conceptions of sport more broadly.

Cytokine-specific Gene-knockout Studies in Oropharyngeal Candidiasis

Oropharyngeal candidiasis is a common clinical problem encountered in patients with defects in innate or cell-mediated immunity. We have previously shown that recovery from chronic oropharyngeal candidiasis is dependent on CD4+ T-cell augmentation of neutrophil and macrophage candidacidal activity, and that the immune response is characterised by the production of cytokines such as IL-12 and IFN-gamma by cells in the local draining lymph nodes, and by the expression of TNF-alpha in the oral tissues. Objective: The purpose of this study was to elaborate on the role of these cytokines in recovery from oropharyngeal candidiasis, by using cytokine-specific gene-knockout mice. Methods: These mice are created by targeted gene mutation (tm1) of embryonic stem (ES) cells microinjected into host embryos. IL-4, IL-10, IL-12, IFN-gamma and TNF-alpha knockout mice, and appropriate controls, were infected orally with 108 viable C. albicans yeasts. The infection was quantified by swabbing the oral cavity and plating on Sabouraud's agar. Results: Tnftm1mice developed an acute severe infection characterized by an increased fungal load in the early stages of infection, but cleared the yeast within the same time frame as control mice (21 days). On the other hand, Il12btm1 mice developed a chronic oropharyngeal infection (120 days) similar to that seen in T-cell deficient (Foxn1nu/Foxn1nu) mutant mice. There was no significant difference between Il4tm1, Il10tm1, and Ifngtm1 mice and their respective controls. Conclusions: Tnftm1 mice may be rendered more susceptible through impaired recruitment of phagocytic cells, and/or impaired killing of C. albicans, whereas Il12btm1 mice may not be capable of activating naïve T-cells or inducing an appropriate cellular immune response.

The role of gender in the construction and evaluation of feedback effectiveness

This study investigated factors that influence managers’ conceptions and subordinates’ perceptions of effective feedback. A social rules perspective was used to operationalize male and female managers’ conceptions of effective negative feedback. In the first study, 68 male and female managers identified their optimal strategies for providing feedback to subordinates. Male and female managers endorsed different goals and tactics for giving negative feedback, particularly in terms of levels of participation and directness. In the second study, 116 male and female subordinates evaluated the comparative effectiveness and difficulty of these and other standard approaches to feedback. The female manager strategy was evaluated by both men and women as generally more task and relationship effective but not more difficult to enact.
