ABSTRACT

This article examines and analyses the authentic experiences of a doctoral student, Kate, in the period just prior to Confirmation, an academic milestone in the Australian doctoral education context. The article uses qualitative phenomenological inquiry as the methodology and employs ideas drawn from the writings of hermeneutical phenomenologist, Paul Ricoeur, especially his notions of narrative, self, time, and human agency. These ideas are utilised in order to ‘get inside’ the constructions of self, the strategies of learning and adaptation, and the experiences of being a doctoral candidate within the milieu of an Australian university education faculty. The writers argue that such a close and personal examination of experience and a hermeneutical approach to analysis is important for a deep understanding about how Kate negotiated her way through the hurdles of early candidature and adapted her life and identities towards success. Particular focus is given to Kate’s experiences of transition and change and the formation of her academic identity that emerged out of these experiences, which led to successful negotiation of this early period of candidature. The research findings reported in this article suggest that Kate’s deep reflexivity, enjoyment of her research and sense of her own well-being as a doctoral student are significant for her perseverance through difficult milestones and ultimately her successful completion of her PhD.  相似文献

Using expanded evidence from the Administrator and Teacher Survey and the High School and Beyond data, the book Politics, Markets, and America's Schools, by Chubb and Moe (C&M), measures differential progress of students who remain in their chosen high schools. Of the variables positively associated with student achievement gain, school organization is clearly significant. C&M describe good school organization as inversely related to the size and dominance of bureaucracy and positively correlated with autonomy. In the absence of a precise definition by C&M this article explores the full meaning of autonomy and finds that when applying it to C&M's ultimate reform proposals, serious inconsistencies emerge. Thus, while they start with the finding that bureaucracy is “unambiguously bad” for school organization, in their last chapter the authors nevertheless recommend reforms in which the existing bureaucracy rather than autonomy is in central charge. In the same vein, their treatment of the voucher system and private schooling, which would clearly promote more autonomy, is decidedly and unexpectedly cool.  相似文献

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

Ankle sprains are the most common injury in sport. With stability being an important risk factor for ankle sprains, a jump-landing protocol that can elicit differences in time-to-stabilisation (TTS) is necessary. The objective of this study was to develop a jump-landing protocol that could identify differences in TTS among healthy, ‘coper’, and unstable ankles of high-level athletes. 61 Division I collegiate athletes (32 females, 29 males; age: 19.9 ± 1.2 years; height: 176.6 ± 9.5 cm; mass: 74.3 ± 10.8 kg) participated in a jump-landing protocol that utilised sporting movements with preparatory steps and a vertical propulsion of the body in two multi-directional jumps. Utilising the landing on a force plate, ground reaction forces were used to quantify TTS. TTS of the unstable group (1.58 ± 0.62s) was significantly longer than the healthy (1.19 ± 0.37s; p = 0.050) and ‘coper’ (1.13 ± 0.49s; p = 0.019) groups in the forward hops. In addition, TTS of the lateral hops in the unstable group (1.55 ± 0.63s) was also significantly longer than the healthy (1.14 ± 0.37s; p = 0.026) and ‘coper’ (1.15 ± 0.39s; p = 0.028) groups. This new jump-landing protocol was able to elicit differences in TTS in high-level athletes that were not found using previous protocols. This new jump-landing protocol could be an effective tool to identify injury risk for high-level athletes.  相似文献
