ABSTRACTIn this paper, we investigate how a Benchlearning program for principals in Norway and Sweden supports changes in Norwegian principals’ leadership practices. The program design builds on principles for practical action research. The aim of the program was to inspire changes in the principals’ leadership practices that encourage innovative school practices. The program includes learning modes such as theoretical inputs, sharing experiences, school visits, training, and trialling of new leadership practices. Drawing on data from participants’ reflections on their learning and changes in their leadership practices, we identify transformations that have been realized and the ways in which the Benchlearning program has supported the transformations. The findings indicate that the program can be seen as a systematic and disciplined process, a ‘meta-practice’, that supports changes in the principals’ leadership practices, their understandings, and the conditions of their practice. More specifically, the findings show that the theoretical inputs and practical learning modes stimulated transformations of the principals’ thinking about leadership practices, what they do in practice and how they relate to others. In particular, the study suggests that the principals’ active participation in trialling new leadership practices in their own schools stimulated transformations. 相似文献

The aim of this study was to investigate whether kinematic proximal-to-distal sequencing (PDS) and speed-summation are common characteristics of both partial and full-swing shots in golf players of different skill levels and genders. A total of 45 golfers participated, 11 male tournament professionals, 21 male and 13 female elite amateurs. They performed partial shots with a wedge to targets at three submaximal distances, 40, 55 and 70 m, and full-swing shots with a 5 iron and a driver for maximal distance. Pelvis, upper torso and hand movements were recorded in 3D with an electromagnetic tracking system (Polhemus Liberty) at 240 Hz and the magnitude of the resultant angular velocity vector of each segment was computed. The results showed a significant proximal-to-distal temporal relationship and a concomitant successive increase in maximum (peak) segment angular speed in every shot condition for both genders and levels of expertise. A proximal-to-distal utilization of interaction torques is indicated. Using a common PDS movement strategy in partial and full-swing golf shots appears beneficial from mechanical and control points of view and could serve the purpose of providing both high speed and accuracy. 相似文献

In the latter half of the twentieth century, the 'Professional Society' was, and continues to be, replaced by a 'Knowledge Society'. One of the characteristics of the 'Professional Society' was its masculine culture and hierarchies. This paper examines the effect that the shift from a 'Professional Society' to a 'Knowledge Society' has had on the careers of female academics. It considers the career paths of vice–chancellors and goes on to examine the effects of geographical mobility on promotions. In addition, the significance of high proportions of professors in highly–rated research departments, and the gender implications of that, is examined. In the concluding section it is argued that, while universities continue to support the hierarchies of the 'Professional Society', it is to the detriment both of women and of knowledge production. 相似文献

The integration of nanomaterials such as carbon nanotubes （CNTs） into microsystems is highly desirable, in order to make use of the unique nanomaterial properties in real devices. However, the CNTtomicrosystem integration is challenging to implement in a manufacturable, cost effective industrial process. This paper presents our work towards a process for making complete, integrated CMOS / MEMS systems with integrated CNT. We demonstrate the feasibility of the process, using roomtemperature process ing, lowcost equipment and consumables, and electrical control with automation possibilities. CNTs are directly integrated at the desired positions in the Si microsystem, forming closed Si / CNT / Si circuits. We explore different designs with the aim to obtain uniform and welldefined CNT synthesis conditions, and show that simplified designs can perform comparably to more complex ones. The Si / CNT / Si circuits obtained can show rectifying （Schottky like） or nearohmic behavior. Gas sensing possibilities are demonstrated, indicating the possibility of monitoring aging/ fermenting of food. Functionalization of CNTs is demon strated, using thermal evaporation of Sn and Pd, opening for selective and sensitive sensors for various gases and ana lytes. Detailed microscopic characterization of the obtained CNTs are presented. 相似文献

The national language of Tanzania is Kiswahili. However, Tanzania has two official languages: English, introduced in colonial times, and Kiswahili, the actual lingua franca spoken by 99 per cent of the population. Kiswahili websites and internet content are gradually increasing, and equipment is becoming more affordable. The research reported on here shows that especially academic staff with good knowledge in information and communication technology (ICT) are using Kiswahili more than others. This gives hope for the future. The language of instruction in Tanzania??s higher education is however English only, resulting in students having to attend lectures and produce their coursework in a language they are not proficient in. Investigating whether University of Dar es Salaam (UDSM) staff and students regard themselves as participants and contributors in a knowledge society, the author??s findings suggest two simultaneous processes: (1) There are still remnants from the colonial system in terms of education and language; (2) At the same time ICT-competent staff and students already do participate in the ICT era in Kiswahili and tend to use Kiswahili in their work and studies. A high number of respondents say they use Kiswahili in most of their ICT communication. There is reason to ask: is the notion of English being the only ICT language possibly decreasing? This article builds on fieldwork conducted at UDSM in 2006, 2008, 2010 and 2011, in connection with the research project ??ICT and Language in Tanzanian Higher Education??. 相似文献

The correlation between mechanical factors of running and running economy as measured by metabolic cost is a subject of much interest in the study of locomotion. However, no change in running technique has been shown to result in an immediate improvement in running economy on an intra-individual basis. To evaluate the effect of a modified running technique, it is probably necessary that the individual trains with the new technique for a longer period using a feedback system to control the new kinematics. In this study, we examine the feasibility of using visual and auditory feedback to adapt running technique according to a simplistic model of the mechanical cost of running. The model considers only the mechanical work against gravity, which is the product of the magnitude of the vertical displacement of the runner's centre of mass and the step-frequency. In the experiments reported here, 18 trained runners, running at 16 km · h(-1) on a treadmill, were given feedback on these parameters together with indicated target levels. In almost all cases, the runners were able to adjust their technique accordingly. 相似文献

The parents of 14 students with disabilities participated in interviews to evaluate the support they received during their child's transition to an integrated educational placement, to explore their concerns, and to discuss the effects of integration. Although parents identified areas of concern, they consistently expressed satisfaction regarding the outcomes of integrating their child, including professional and personal support. Responses emphasized the importance of commitment from local school districts and professionals, an individualized approach to parent involvement, and ongoing communication with parents. 相似文献

A white person from the Global North, referred to in Kiswahili as a mzungu, can hardly conduct research anonymously, observe unnoticed or merge with staff and students in the context of African university classrooms. This article builds on the author’s six years of research at the University of Dar es Salaam (UDSM) in Tanzania, examining staff and students’ everyday practices in terms of how they are characterised by linguistic constraints. Using an autoethnographic, self-reflective and retrospective approach, the author discloses some of her experience during fieldwork as a researcher on the university campus. Through this form of qualitative research, she connects her personal experience to the discourse on the language of instruction policy and practices in higher education in Tanzania. The aim of her self-reflection is to understand the wider meanings of how cultural, political and social language practices unfold in staff and students’ daily lives. Using the concepts of insider and outsider, preconception, and theory-ladenness of observation, the author aims to depict the challenges and limits of being a researcher in a totally unfamiliar context. During her fieldwork, using a mixed-methods approach of questionnaires, interviews and participating observation, the author also kept a notebook with her. She made field notes of self-observation, reflecting on her reactions to what she encountered in the research process. While making these notes was not deliberately a part of the data collection, it was an important way of talking to herself. In retrospect, a few years after submitting her doctoral thesis, these notes have become more important to her. The purpose of this article is twofold: on the one hand, the author reveals some of her own experience as a researcher in unaccustomed surroundings, on the other hand, she uses her personal experience to describe, question and shed light on the discrepancies caused by language practices in Tanzanian higher education. 相似文献
