Using decision support systems to facilitate the social process of knowledge management     

Gilberto?Montibeller  Duncan?ShawEmail author  Mark?Westcombe 《知识管理研究与实践》2006,4(2):125-137

The social processes involved in engaging small groups of 3–15 managers in their sharing, organising, acquiring, creating and using knowledge can be supported with software and facilitator assistance. This paper introduces three such systems that we have used as facilitators to support groups of managers in their social process of decision-making by managing knowledge during face-to-face meetings. The systems include Compendium, Group Explorer (with Decision Explorer) and V*I*S*A. We review these systems for group knowledge management where the aim is for better decision-making, and discuss the principles of deploying each in a group meeting.  相似文献   

Closing the Circle: Action research partnerships towards better learning and teaching in schools     

Moyra Evans  Pam Lomax  Helen Morgan 《Cambridge Journal of Education》2000,30(3):405-419

This paper addresses the call for evidence-based practice by describing an initiative in school-university partnership that has led to the establishment of a community of teacher researchers whose investigations provide the evidence upon which they make decisions to improve their teaching. This is a new way of approaching the idea of evidence-based practice, where the evidence comes through personal testimony that 'rings true'. In this mode of research the processes of research are shared so that the outcomes of the research may be disseminated through 'transferability' rather than 'generalisability'. The first part describes the partnership, which involved the adaptation of existing structures in the school (staff development) and the university (accreditation) to create a new more democratic, more productive relationship. The second part of the paper describes the work of one teacher who applied the principles from her own learning within the teacher group to her management of her students' learning in such a way that the excitement of independent learning that had been a feature of the teacher group was transferred to the students. The third part of the paper addresses the politics of such research and makes a case for including teachers' and students' knowledge of their own practice as evidence to inform policy development.  相似文献

Associations of object control motor skill proficiency,game play competence,physical activity and cardiorespiratory fitness among primary school children     

Andrew Miller  Narelle Eather  Mitch Duncan  David Revalds Lubans 《Journal of sports sciences》2019,37(2):173-179

This study investigated if object control relates to children’s game play competence, and examined these competencies as correlates of physical activity and cardiorespiratory fitness. Game play (Game Performance Assessment Instrument), object control (The Test Gross Motor Development-3), moderate-to-vigorous physical activity (Accelerometry), and cardiorespiratory fitness (20-metre shuttle) assessments were completed for 107 children (57% Female, 43% Male) aged 9–12 years (M 10.53, SD 0.65). Two-level regression of object control on game play competence, and object control and game play competence on physical activity and cardiorespiratory fitness assessed associations. Object control competence was positively associated with game play competence (Std. B = 0.25, t (104.77) = 2.38, p = 0.001). Game play competence (Std. B = 0.33, t (99.81) = 5.21, p < 0.000) was more strongly associated with moderate-to-vigorous physical activity than object control competence (Std. B = 0.20, t (106.93) = 2.96, p = 0.003). Likewise, game competence (Std. B = 0.39, t (104.41) = 4.36, p < 0.000) was more strongly associated with cardiorespiratory fitness than object control competence (Std. B = 0.22, t (106.69) = 2.63, p = 0.002). Object control and game competence are both important as correlates of physical activity and cardiorespiratory fitness in children.  相似文献

Adolescent physical activity levels: discrepancies with accelerometer data analysis     

Greig R.M. Logan  Scott Duncan  Nigel K. Harris  Erica A. Hinckson  Grant Schofield 《Journal of sports sciences》2016,34(21):2047-2053

This study investigated the effects of epoch length and cut point selection on adolescent physical activity intensity quantification using vertical axis and vector magnitude (VM) measurement with the ActiGraph GT3X+ accelerometer. Four hundred and nine adolescents (211 males; 198 females) aged 12–16 years of age wore accelerometers during waking hours. The GT3X+ acceleration counts were reintegrated into 1, 5, 15, 30 and 60 s epoch lengths for both vertical axis and VM counts. One cut point was applied to vertical axis counts and three different cut points were applied to VM counts for each epoch length. Significant differences (P < 0.01) in mean total counts per day were observed between vertical axis and VM counts, and between epoch lengths for VM only. Differences in physical activity levels were observed between vertical and VM cut points, and between epoch lengths across all activity intensities. Our findings illustrate the magnitude of differences in physical activity outcomes that occur between axis measurement, cut points and epoch length. The magnitude of difference across epoch length must be considered in the interpretation of accelerometer data and seen as a confounding variable when comparing physical activity levels between studies.  相似文献   

Effects of increasing and decreasing physiological arousal on anticipation timing performance during competition and practice     

Michael J. Duncan  Mike Smith  Elizabeth Bryant  Emma Eyre  Kathryn Cook  Joanne Hankey 《European Journal of Sport Science》2016,16(1):27-35

The aim of this study was to investigate if the effects of changes in physiological arousal on timing performance can be accurately predicted by the catastrophe model. Eighteen young adults (8 males, 10 females) volunteered to participate in the study following ethical approval. After familiarisation, coincidence anticipation was measured using the Bassin Anticipation Timer under four incremental exercise conditions: Increasing exercise intensity and low cognitive anxiety, increasing exercise intensity and high cognitive anxiety, decreasing exercise intensity and low cognitive anxiety and decreasing exercise intensity and high cognitive anxiety. Incremental exercise was performed on a treadmill at intensities of 30%, 50%, 70% and 90% heart rate reserve (HRR) respectively. Ratings of cognitive anxiety were taken at each intensity using the Mental Readiness Form 3 (MRF3) followed by performance of coincidence anticipation trials at speeds of 3 and 8 mph. Results indicated significant condition × intensity interactions for absolute error (AE; p = .0001) and MRF cognitive anxiety intensity scores (p = .05). Post hoc analysis indicated that there were no statistically significant differences in AE across exercise intensities in low–cognitive anxiety conditions. In high–cognitive anxiety conditions, timing performance AE was significantly poorer and cognitive anxiety higher at 90% HRR, compared to the other exercise intensities. There was no difference in timing responses at 90% HRR during competitive trials, irrespective of whether exercise intensity was increasing or decreasing. This study suggests that anticipation timing performance is negatively affected when physiological arousal and cognitive anxiety are high.  相似文献

The Mediation of Spectator Sport     

Margaret Carlisle Duncan  Barry Brummett 《Research quarterly for exercise and sport》2013,84(2):168-177

Abstract

This study employs the theory of “media logic” and the method of hermeneutical criticism to demonstrate some effects of a major social institution, television, on the “text” of experiencing spectator sports. The study finds that the medium of television makes spectator sports into an experience which incorporates narrative, intimacy, commodification, and rigid time segmentation. The conventions imposed by television on spectator sports are presented here as powerfully affecting the meanings which televised sports have for their audiences.  相似文献
