In this paper, we discuss how ‘with-woman’ midwifery and doula care provide resources for rethinking the theory and practice of academic supervision from a feminist perspective. We identify how the tradition of accompaniment in both birth work and academia is under threat given the economic reforms facing public sector education and health care. Despite these pressures, we suggest that the practice of focusing on the pregnant woman as an ‘expert’ on her pregnancy rather than on the foetus or the delivery – that is, the ‘product’ of her pregnancy – would help transform how we theorise and practise academic supervision. The aim of the supervisory relation would mean supporting the student’s direct relation to the intellectual, embodied and emotional process of completing the PhD. Such an approach suggests ways in which the pedagogical practices of contemporary midwifery and doula care can inform academic supervision in the neoliberal university. 相似文献

This article addresses the rhetoric of performance assessment with research on important claims about science performance assessments. We found the following: (a) Concepts and terminology used to refer to performance assessments often were not consistent within and across researchers, educators, and policy-makers. (b) Performance assessments are highly sensitive not only to the tasks and the occasions sampled, but also to the method (e.g., hands-on, computer simulation) used to measure performance. (c) Performance assessments do not necessarily tap higher-order thinking, especially when they are poorly designed. (d) Performance assessments are expensive to develop and use: technology is needed for developing these assessments in an efficient way. (e) Performance assessments do not necessarily have the expected positive impact on teachers' teaching and students' understanding. (f) If teachers are to use performance assessments in their classrooms, they need professional development to help them construct the necessary knowledge and skills. This article attempts to address some of these realities by presenting a conceptual framework that might guide the development and the evaluation of performance assessments, as well as steps that might be taken to create a performance assessment technology and develop teacher inservice programs. © 1996 John Wiley & Sons, Inc. 相似文献

β-hydroxy-β-methylbutyrate (calcium: HMB-Ca and free acid: HMB-FA) and α-hydroxyisocaproic acid (α-HICA) are leucine metabolites that have been proposed to improve body composition and strength when combined with resistance exercise training (RET). In this double-blind randomized controlled pragmatic trial, we evaluated the effects of off-the-shelf supplements: α-HICA, HMB-FA and HMB-Ca, on RET-induced changes in body composition and performance. Forty men were blocked randomized to receive α-HICA (n?=?10, fat-free mass [FFM]?=?62.0?±?7.1?kg), HMB-FA (n?=?11, FFM?=?62.7?±?10.5?kg), HMB-Ca (n?=?9, FFM?=?65.6?±?10.1?kg) or placebo (PLA; n?=?10, FFM?=?64.2?±?5.7?kg). The training protocol consisted of a whole-body resistance training routine, thrice weekly for 8 weeks. Body composition was assessed by dual-energy x-ray absorptiometry (DXA) and total body water (TBW) by whole-body bioimpedance spectroscopy (BIS), both at baseline and at the end of weeks 4 and 8. Time-dependent changes were observed for increase in trunk FFM (p?0.05). No statistically significant between-group or group-by-time interactions were observed. Supplementation with HMB (FA and Ca) or α-HICA failed to enhance body composition to a greater extent than placebo. We do not recommend these leucine metabolites for improving body composition changes with RET in young adult resistance trained men. 相似文献

High Intensity Interval Training (HIIT) can be performed with different effort to rest time-configurations, and this can largely influence training responses. The purpose of the study was to compare the acute physiological responses of two HIIT and one moderate intensity continuous training (MICT) protocol in young men. A randomised cross-over study with 10 men [age, 28.3?±?5.5years; weight, 77.3?±?9.3?kg; height, 1.8?±?0.1?m; peak oxygen consumption (VO2peak), 44?±?11?mL.kg?1.min?1]. Participants performed a cardiorespiratory test on a treadmill to assess VO2peak, velocity associated with VO2peak (vVO2peak), peak heart rate (HRpeak) and perceived exertion (RPE). Then participants performed three protocols equated by distance: Short HIIT (29 bouts of 30s at vVO2peak, interspersed by 30s of passive recovery, 29?min in total), Long HIIT (3 bouts of 4?min at 90% of vVO2peak, interspersed by 3?min of recovery at 60% of vVO2peak, 21?min in total) and MICT (21?min at 70% of vVO2peak). The protocols were performed in a randomised order with ≥48 h between them. VO2, HRpeak and RPE were compared. VO2peak in Long HIIT was significantly higher than Short HIIT and MICT (43?±?11 vs 32?±?8 and 37?±?8?mL.kg?1.min?1, respectively, P?0.05), as well as peak HR (181?±?10 vs 168?±?8 and 167?±?11, respectively, P?0.05), and RPE (17?±?4 vs 14?±?4 and 15?±?4, respectively, P?0.05), with no difference between Short HIIT and MICT. In conclusion, Long HIIT promoted higher acute increases in VO2, HR and RPE than Short HIIT and MICT, suggesting a higher demand on the cardiorespiratory system. Short HIIT and MICT presented similar physiologic and perceptual responses, despite Short HIIT being performed at higher velocities. 相似文献

A sport-specific measure of moral disengagement was developed in 2 studies. In Study 1, a 59-item questionnaire was developed and tested with 308 athletes from 5 team sports. A series of confirmatory factor analyses (CFA) testing different models suggested the model that best fitted the data had 6 first-order factors that could be represented by 1 second-order factor. Study 2 involved 305 athletes from the same 5 sports. CFA confirmed the 6-factor, second-order structure for the final 32-item measure. Results from Study 2 supported the construct validity of the scale, providing evidence for the factorial, concurrent, convergent, and discriminant validity. The Moral Disengagement in Sport Scale (MDSS) is proposed as a valid and reliable measure of moral disengagement for use in the sport context. 相似文献

When cynical distance and ironic posturing have become the prevalent means of relating to public life, political humour is no longer considered subversive. It has been argued that both in Russia and the United States, ideology has co-opted satire, meaning that citizens can consume outrage passively through various satirical media products, thereby displacing outrage and abstaining from more active forms of resistance. This articles explores the twenty-first century potential of irony and cynicism to disrupt and subvert through parody, be it in the form of political satire or ironic protest, examining how similar paradigms are expressed across different geographical contexts. 相似文献

The aim of the present study was to analyse the training load in wheelchair basketball small-sided games and determine the relationship between heart rate (HR)-based training load and perceived exertion (RPE)-based training load methods among small-sided games bouts. HR-based measurements of training load included Edwards’ training load and Stagno’s training impulses (TRIMPMOD) while RPE-based training load measurements included cardiopulmonary (session RPEres) and muscular (session RPEmus) values. Data were collected from 12 wheelchair basketball players during five consecutive weeks. The total load for the small-sided games sessions was 67.5 ± 6.7 and 55.3 ± 12.5 AU in HR-based training load (Edwards’ training load and TRIMPMOD), while the RPE-based training loads were 99.3 ± 26.9 (session RPEres) and 100.8 ± 31.2 AU (session RPEmus). Bout-to-bout analysis identified greater session RPEmus in the third [P < 0.05; effect size (ES) = 0.66, moderate] and fourth bouts (P < 0.05; ES = 0.64, moderate) than in the first bout, but other measures did not differ. Mean correlations indicated a trivial and small relationship among HR-based and RPE-based training loads. It is suggested that HR-based and RPE-based training loads provide different information, but these two methods could be complementary because one method could help us to understand the limitations of the other. 相似文献
