Jordanian national football Muslimat players: Interrupting Islamophobia in FIFA's hijab ban

Background: Though musli m females exclusion from physical activities and sports has concerned scholars for years, they are still being theorized out of context and out of history and not as agents in their own lives. Within the prevailing context of the ‘War on Terror,’ muslim females are becoming more racialized in sports and are unnecessarily constructed as needing protection and void of any agency. In 2010, a crisis emerged out of the International Federation of Association Football's (FIFA) erratic interpretation of Law 4 which excluded muslim females players with a head/cover gear deemed unsafe on the field. This crisis highlighted the importance of understanding not only the targeted exclusion of muslim female players but also the importance of working with muslim female national football players and the possibilities of them resisting the racializing and gendering logics of a mega-sport institution such as FIFA.

Purpose: The purpose of this paper is to understand how five women football players on the Jordanian national team negotiated FIFA's ‘hijab ban’ of 2011. Particularly, it seeks the perspectives of the players themselves – whether they are wearing the head and/or neck cover or not and whether their muslimness is visible or not – and their stories of how they negotiated FIFA's ‘hijab ban’ (2011–2012).

Methodology: This paper is part of a larger critical qualitative study based on (1) dialogical interviews with five football players on the Jordanian national team, (2) material the players crafted and used to campaign against FIFA's ‘hijab ban,’ (3) players’ journals, (4) email correspondence and (5) web-based campaigning material. I deploy arab-muslim feminist scholars’ more complicated understanding of the hijab and theorize of how muslim women's bodies are regulated by two interconnected hijabophobias, the Islamist and Western-Islamophobic.

Findings: The findings are organized in the following themes: (1) experiencing humiliation and injustice, (2) exposing FIFA's Islamophobic standpoint and (3) resisting through solidarity and activism. The results suggest that the muslim female football players on the Jordanian national team exposed the FIFA's Islamophobic hijabophobia in its interpretation of Law 4. They acted with resilience and political savviness to regain the right to play while being muslim female under FIFA's laws. This suggests that muslim females are active agents in their own lives and on a global level. They are able to counter the racializing injustices produced by very powerful sport institutions. Non-muslim/Western policy-makers, researchers, teachers and trainers working among muslim women and youth need to consider this example as a frame to their participatory research, critical pedagogies, and physical education (PE) and sport curricula. They need to recognize that we are living a moment in history in which muslim women's bodies are sites of both the Islamist and the colonialist anxieties in their struggles for power. Thus, they need to urgently be engaged in the theories and pedagogical approaches that challenge both the Islamist and the Islamophobic hijabophobias in sport and PE.     

Development of a grinding-specific performance test set-up

Abstract

The aim of this study was to develop a performance test set-up for America's Cup grinders. The test set-up had to mimic the on-boat grinding activity and be capable of collecting data for analysis and evaluation of grinding performance. This study included a literature-based analysis of grinding demands and a test protocol developed to accommodate the necessary physiological loads. This study resulted in a test protocol consisting of 10 intervals of 20 revolutions each interspersed with active resting periods of 50 s. The 20 revolutions are a combination of both forward and backward grinding and an exponentially rising resistance. A custom-made grinding ergometer was developed with computer-controlled resistance and capable of collecting data during the test. The data collected can be used to find measures of grinding performance such as peak power, time to complete and the decline in repeated grinding performance.     

全球原镁需求预测及中国合理产能分析

镁被誉为"21世纪最具开发和应用潜力的绿色工程材料",是重要的战略性金属材料。本文运用部门分析预测法,对中国、北美、欧洲、日本等全球主要国家和地区原镁消费历史和未来原镁需求进行了系统分析和预测,结果表明:未来15年全球原镁消费将持续增长,2020年、2030年需求量将分别达到234万t和303万t;较目前增加1.87倍和2.72倍;亚太地区将成为全球原镁需求的主要地区,2020年和2030年其需求全球占比将分别达到58.38%和68.97%;中国将成为未来全球原镁需求的拉动者,2013-2030年全球原镁需求增量的78.50%将来自中国。以全球需求为基础,结合全球一次和二次资源供应现状及未来趋势,针对国内产能严重过剩的问题,提出2020年和2030年,中国原镁合理产能分别为107~130万t和203~247万t。建议国家应提高行业准入标准,淘汰落后产能,提高行业集中度;同时加大研发力度,提高中国原镁生产和利用领域的全球竞争力。

现代足球比赛进球基本特征与规律研究——以第14-20届世界杯足球赛进球为例

摘要：运用文献资料调研、观察及数理统计等方法,对第14-20届世界杯足球赛1051个进球的方式、射门区域、及进攻形式等特征进行研究,以探讨现代足球比赛特征与规律。研究结果表明：7届世界杯场均进球数呈逐届下降趋势;比赛下半场比上半场进球率高,反映出现代足球在重视攻守平衡的同时更加注重进攻效率。罚球区2区内外区域是现代足球比赛射门进球最佳区域。前锋进球数最多,前锋和攻击型中场球员区分不再明确,全能型的队员位置职能已成为现代足球位置特征发展规律。现代足球比赛中脚射是最主要得分方式,立体高空头顶球技战术也已成形。随着传球次数的增加而进球明显减少的趋势,“直接打法”战术已成为现代足球进攻战术发展主流趋势。中路进攻、定位球进攻已成为现代足球进攻战术发展主要方向。前场及中前场已成为现代足球最佳有效地发动进攻进球区域。
