This paper suggests that the dominant discourse of lifelong learning is a political rather than an educational discourse. On this view, lifelong learning enables the deconstruction of welfare to be effected through the reconstruction of citizenship. Democratic citizenship properly understood, on the other hand, depends on determined progress towards a more equitable distribution of material and cultural resources among citizens. Education on its own can do little to ensure that such structural change takes place. It is, nevertheless, the task of critical adult education, as distinct from economistic models of lifelong learning, to raise such questions as urgent issues for democratic deliberation and debate, and to expand our notions of what it means to be active citizens in a democratic society. The paper contains the text of a talk given at the annual study conference of the UK's National Institute of Adult Continuing Education in April 2002.  相似文献

Controversy surrounding a Catholic philosophy of education and the Catholic “identity” of institutions of higher learning reveals the vitality and the genuine liberality of contemporary Catholic higher education. Rather than being symptoms of political correctness or of a lost capacity to celebrate Catholic or any other particularity, these controversies reveal the openness and authenticity of Catholic higher education. They show the willingness of many leaders in Catholic higher education to let go of ecclesiastical sectarianism, of absolute claims inconsistent with God's universal love and availability, and of classicism, and to embrace a reverent religious pluralism, a historical perspective, and the sheer exhilaration of intellectual discourse which aims to be universal. Such openness is no more risky than the more narrow and triumphal perspectives it replaces, and is well worth the risks.  相似文献

This paper presents the results of a major investigation by questionnaire of author attitudes towards scholarly publishing, which was funded by the Publisher's Association. Altogether, the views of nearly 4,000 authors were obtained and this paper concerns just those thousand or so authors who accepted the invitation to write freely about their own personal feelings and experiences. Using QSR N6 textual analysis software, their comments were processed and themes extracted. While the rest of the questionnaire, which was formed of closed‐question, tick‐box type questions, clearly must have had some impact on their thinking, the authors had considerable latitude in regard to what they could say. The paper provides a unique opportunity to hear their views directly. The pressing topics turned out to be (in rough order of concern): the peer‐review system, copyright, journal prices, alternative business models for journal publishing, big deals, Elsevier, electronic publishing and digital journals.  相似文献

The aims of this study were to examine and compare selected physiological and metabolic responses of wheelchair athletes in two paraplegic racing classes [T3: n = 8 (lesion levels T1-T7; paraplegics); T4: n = 9 (lesion levels below T7; paraplegics)] to prolonged exercise. In addition, we describe the responses of three tetraplegic athletes [T2: n = 3 (lesion levels C6/C7: tetraplegics)]. Twenty athletes completed 90 min of exercise at 75% VO2peak on a motorized treadmill adapted for wheelchairs. The mean (+/- s) heart rates of the T3 and T4 racing classes were 165 +/- 2 and 172 +/- 6 beats.min-1, respectively. For the T4 racing class, heart rate gradually increased during the test (P < 0.05), whereas for the T3 racing class, heart rate reached a plateau after an initial increase. The mean heart rate of the tetraplegics was 114 +/- 3 beats.min-1. The T3 and T4 classes exhibited similar respiratory exchange ratios, plasma lactate and glucose concentrations throughout the test. For both the T3 and T4 racing class, free fatty acid, glycerol, ammonia, urea and potassium concentrations had increased from resting values by the end of the test (P < 0.05). In conclusion, the results of this study suggest that endurance-trained wheelchair athletes are able to maintain velocities equivalent to the same relative exercise intensity (75% VO2peak) for prolonged periods irrespective of lesion level.  相似文献

The purpose of this study was to further understand the biomechanical differences between the standing and crouch starting methods, and to investigate whether one of the starting styles provides better acceleration and proves to be faster. Six university track team sprinters performed 2 x 3 x 50 m trials. Digitised video, photocell timing, and velocity data revealed that during the first steps of the performance the standing start produced higher body centre of mass horizontal velocity than the crouch start. This may be due to the longer distance between the feet in the standing start, which caused longer push-off phases, and the work against gravity in the crouch start. However, this advantage in horizontal velocity disappeared by the 10 m mark, where similar velocities were recorded with both start styles. Further, there was no statistically significant difference between the two starting styles in horizontal velocity at the 25 m mark, nor in the time to reach the 25 m or 50 m mark. Regarding relay running, where athletes need to decide to adopt either a crouch start without starting blocks or a standing start, there seems to be no specific reason for outgoing athletes to use a crouch start, although this area warrants further investigation.  相似文献
