In this paper we describe a UK‐based participatory action research project that looks beyond the discourse of tolerance to investigate and challenge heteronormative processes in primary schools through reflective action research. This 28‐month ESRC‐funded project supports 15 primary teachers working in schools in three regions of the UK to develop action research projects that address lesbian, gay, bisexual and transgender equality in their own schools and classrooms. In this paper we will examine how the original principles on which the project design was based have manifested themselves throughout the course of the project, drawing upon examples of classroom practice and reflective discussions among project team members. We will explore how designing intentionally for collective participation has produced spaces for people to do and think in ways that have not only gone beyond what we imagined but have also challenged and sometimes contradicted our own ways of thinking. 相似文献

There is limited research studying fluid and electrolyte balance in rugby union players, and a paucity of information regarding the test–retest reliability. This study describes the fluid balance of elite rugby union players across multiple squads and the reliability of fluid balance measures between two equivalent training sessions. Sixty-one elite rugby players completed a single fluid balance testing session during a game simulation training session. A subsample of 21 players completed a second fluid balance testing session during an equivalent training session. Players were weighed in minimal clothing before and after each training session. Each player was provided with their own drinks which were weighed before and after each training session. More players gained body weight (9 (14.8%)) during training than lost greater than 2% of their initial body mass (1 (1.6%)). Pre-training body mass and rate of fluid loss were significantly associated (r?=?0.318, p?=?.013). There was a significant correlation between rate of fluid loss in sessions 1 (1.74?±?0.32?L?h?1) and 2 (1.10?±?0.31?L.?h?1), (r?=?0.470, p?=?.032). This could be useful for nutritionists working with rugby squads to identify players with high sweat losses. 相似文献

Our purpose was to compare joint loads between habitual rearfoot (hRF) and habitual mid/forefoot strikers (hFF), rearfoot (RFS) and mid/forefoot strike (FFS) patterns, and shorter stride lengths (SLs). Thirty-eight hRF and hFF ran at their normal SL, 5% and 10% shorter, as well as with the opposite foot strike. Three-dimensional ankle, knee, patellofemoral (PF) and hip contact forces were calculated. Nearly all contact forces decreased with a shorter SL (1.2–14.9% relative to preferred SL). In general, hRF had higher PF (hRF-RFS: 10.8 ± 1.4, hFF-FFS: 9.9 ± 2.0 BWs) and hip loads (axial hRF-RFS: ?9.9 ± 0.9, hFF-FFS: ?9.6 ± 1.0 BWs) than hFF. Many loads were similar between foot strike styles for the two groups, including axial and lateral hip, PF, posterior knee and shear ankle contact forces. Lateral knee and posterior hip contact forces were greater for RFS, and axial ankle and knee contact forces were greater for FFS. The tibia may be under greater loading with a FFS because of these greater axial forces. Summarising, a particular foot strike style does not universally decrease joint contact forces. However, shortening one’s SL 10% decreased nearly all lower extremity contact forces, so it may hold potential to decrease overuse injuries associated with excessive joint loads. 相似文献

This paper examines the implications of the context of creation on the current and potential future uses of the records produced by the Comissao de Acolhimento, Verdade e Reconciliacao de Timor-Leste (Commission for Reception, Truth and Reconciliation, or CAVR). Given that the CAVR relied heavily on the testimony of the East Timorese people in its investigations that addressed a 25-year period, this paper considers the nature of memory and the role it played in creating and shaping the CAVR records. It also addresses the potential influences of the CAVR records, particularly the final report, Chega!, in shaping what will be known about this period by the Timorese people. The paper concludes with a discussion of the potential role of the CAVR records in contributing to the history of Timor-Leste. Although truth commissions are a problematic form of truth telling, with significant implications for the writing of history, the records of the CAVR are an invaluable source of information for Timorese history. If future users can recognize the CAVR records as the products of the context of their creation, these records will have a critical role to play in the development of history within Timor-Leste. 相似文献

In this paper we present a number of metrics for usage of the SAO/NASA Astrophysics Data System (ADS). Since the ADS is used by the entire astronomical community, these are indicative of how the astronomical literature is used. We will show how the use of the ADS has changed both quantitatively and qualitatively. We will also show that different types of users access the system in different ways. Finally, we show how use of the ADS has evolved over the years in various regions of the world. 相似文献
