What is reconciliation? A source of historical puzzlement and contemporary controversy over how to make history, this question asks after those words which constitute a beginning (again), that moment in which endless cycles of conflict give way to the hope for “unity in difference.” Concerned with the dynamics of its operation, the present essay contends that reconciliation is a rhetorical concept, a performance and norm of rhetorical practice that transcends violence less than it turns its historical justification toward mutual oppositions that call for(th) the character (ethos) of understanding. A challenge to both the logic and politics of identity, an opposing and relating of that which is held to be exclusive, reconciliation is thus difficult to define. From a reading of the concept's history, I investigate this definitional puzzle through consideration of how the substance of reconciliation appears within its potential, the capacity to open a time for expression, invent the grounds for speech-action, and abide in the risks that attend the power to name. To make new in relation, reconciliation's promise demands significant faith in the works of words.  相似文献

Press releases concerning the Australasian Survey of Student Engagement (AUSSE) results warn that university students in Australia and New Zealand are less engaged than their peers at United States institutions. Such warnings about student engagement and interactions then become targets for improvement on Australasian universities’ strategic plans. In considering New Zealand university students’ survey responses, we examined AUSSE and the US National Survey of Student Engagement (NSSE) data for 2009 and 2010 with respect to all items that load on the five scales these instruments share. We argue that most of the observed differences in responses, response distributions and subsequent scale scores can be attributed to differences in educational pathways and cultures between the USA and New Zealand. Consequently, considerable caution in these trans-Pacific comparisons is warranted, particularly when formulating policy and practices to improve student engagement in New Zealand based on methods that have been employed in different educational contexts.  相似文献

Background:In a sprint cross-country(XC)ski competition,the difference in recovery times separating the first and the second semi-final(SF)heats from the final(F)may affect performance.The aim of the current study was to compare the effects of longer vs.shorter recovery periods prescribed between the 3 knock-out races of a simulated sprint XC ski competition involving a prologue(P),quarter-final(QF),SF,and F.Methods:Eleven well-trained XC ski athletes completed 2 simulated sprint XC ski competitions on a treadmill involving 4×883-m roller-ski bouts at a 4°incline using the gear 3 ski-skating sub-technique.The first 3 bouts were completed at a fixed speed(PFIX,QFFIX,and SFFIX)corresponding to~96%of each individual’s previously determined maximal effort.The final bout was performed as a self-paced sprint time trial(FSTT).Test conditions differed by the time durations prescribed between the QFFIX,SFFIX,and FSTT,which simulated real-world XC ski competition conditions using maximum(MAX-REC)or minimum(MIN-REC)recovery periods.Results:The FSTT was completed 5.4±5.5 s faster(p=0.009)during MAX-REC(179.2±18.1 s)compared to MIN-REC(184.6±20.0 s),and this was linked to a significantly higher power output(p=0.010)and total metabolic rate(p=0.009).The pre FSTT blood lactate(BLa)concentration was significantly lower during MAX-REC compared to MIN-REC(2.5±0.8 mmol/L vs.3.6±1.6 mmol/L,respectively;p=0.027),and the pre-to-post FSTT increase in BLa was greater(8.8±2.1 mmol/L vs.7.1±2.3 mmol/L,respectively;p=0.024).No other differences for MAX-REC vs.MIN-REC reached significance(p>0.05).Conclusion:Performance in a group of well-trained XC skiers is negatively affected when recovery times between sprint heats are minimized which,in competition conditions,would occur when selecting the last QF heat.This result is combined with a higher pre-race BLa concentration and a reduced rise in BLa concentration under shorter recovery conditions.These findings may help inform decision making when XC skiers are faced with selecting a QF heat within a sprint competition.  相似文献

This study investigated differences in generic and soccer specific motor coordination, as well as speed and agility depending on age and maturity in elite youth soccer players (U10-U15, N = 619). Measurements included body height, body weight and sitting height to estimate age at peak height velocity (APHV); three Körperkoordinationstest für Kinder subtests (i.e. jumping sideways (JS), moving sideways (MS), balancing backwards (BB)) to assess generic motor coordination; the UGent dribbling test for soccer specific motor coordination; a 5m/30m sprint and T-test for speed and agility, respectively. Age specific z-scores of the predicted APHV identified players as earlier, on time or later maturing. (M)ANOVA analyses showed significant age by maturity interaction effects for the speed and agility test cluster, revealing maturity related differences in U14 and U15 players. Next to an overall higher performance with age for all test clusters (η2 0.080–0.468), earlier maturing players outperformed their later maturing peers in 5m/30m sprinting. The opposite was seen for JS and BB. So, players’ maturity status should be taken into account to adequately value performance in talent identification. Also, the focus on characteristics that appear to be minimally biased by an earlier maturational timing (i.e. motor coordination) should be increased.  相似文献

The present investigation was carried out to examine the incidence and pattern of injuries in adolescent multisport athletes from youth sports academy. Injury data were prospectively collected from 166 athletes during the seasons from 2009 to 2014. A total of 643 injuries were identified, 559 (87.0%) were time-loss injuries. The overall injury incidence was 5.5 (95% confidence interval CI: 5.1–6.0), the incidence of time-loss injuries was 4.8 (95% CI: 4.4–5.2), the incidence of growth conditions was 1.2 (95% CI: 1.0–1.4) and incidence of serious injuries was 0.6 (95% CI: 0.5–0.8) per 1000?h of exposure. The prevalence of overuse injuries was 50.3%. Growth conditions represented 20.0%. Most of the injuries (67.0%) involved the lower extremities, and both foot and ankle were the most predominant injured body parts (22.0%). Knee injuries were mostly from overuse (50 vs. 23, p?=?.02), whereas foot and ankle injuries resulted from an acute mechanism (94 vs. 31, p?<?.0001). Minor and moderate injuries accounted for 87.0%. Muscle, tendon and osteochondrosis injuries accounted for 52.0% of all injuries. Comparing groups, squash sport was having the highest injury incidence (8.5 injuries per athlete). Higher exposure was associated with greater overuse relative risk (RR?=?1.03, 95% CI: 1.01–1.014, p?<?.001). In conclusion, the results of this study identified a high incidence of injuries in this youth sports population. Striking was the prevalence of overuse injuries of 50%, which suggests the need for injury prevention protocols for adolescent highly trained athletes.  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

Background: Research indicates that physical education teacher education (PETE) has only limited impact on how physical education (PE) is taught in schools. In this paper, our starting point is that the difficulties of challenging the dominating subject traditions in PE could be due to difficulties of challenging certain epistemological assumptions recurring in significant PETE subject matter and didactics courses.

Purpose: The purpose of this paper is to scrutinise how knowledge is expressed in learning outcomes formulated in curriculum documents at PETE institutions in Sweden and to discuss the potential educational consequences of the epistemological assumptions underlying the analysed expressions of knowledge.

Setting and participants: This paper offers possible explanations for the difficulties of influencing subject traditions in PE through analysing learning outcomes formulated in PETE curriculum documents. The analysis is based on 224 learning outcomes collected from a total of 18 course syllabi, spread at 6 PETE institutions in Sweden.

Research design, data collection and analysis: The documents have been collected through contact by e-mail with representatives for each institution. Through the analysis different themes in the material have been identified and clustered together. Inspired by Fenstermacher's ideas about teacher knowledge as propositional knowledge and performance knowledge, our ambition is to discuss the potential educational consequences of the epistemological assumptions underpinning the analysed learning outcomes.

Findings: In the collected learning outcomes, the following themes were identified: teaching PE, interpreting curriculum documents, physical movement skills, science, social health, pedagogy, critical inquiry, and research methods. In most of the identified themes, the learning outcomes represent both subject matter knowledge and general teacher knowledge and are also formulated with an integrated perspective on so-called performance knowledge and propositional knowledge. However, particularly in the themes science and physical movement skills, two very influential themes, the learning outcomes are limited to subject matter knowledge and the concept of knowledge in these themes is also limited and unilateral in relation to ideas of different forms of teacher knowledge.

Conclusions: We argue that a decontextualisation of knowledge, in this paper identified through dissolving science from its use in practice and through detaching physical movement skills from other conceptual foundations, contributes to the reproduction of subject traditions that render PE teachers incapable of critically reflecting over their practice, for instance how different groups of students benefit or suffer from the teaching of certain content. Drawing on the work of Tinning, we offer an explanation as to how teacher knowledge in the themes science and physical movement skills, emanating from behaviouristic and craft knowledge orientations, is formulated.  相似文献
