康喜来  袁海瑞 《湖北体育科技》2017,36(1):54-57

运用文献资料法、录像观察法、数理统计法、秩和比法等对进入第31届奥运会男子篮球决赛阶段的12支球队的攻防指标进行了研究。研究显示:在进攻端,美国、西班牙、澳大利亚、塞尔维亚4支球队排在前4名,中国男篮的进攻RSR值为0.21,在所有参赛球队中垫底。在防守端,西班牙、法国、克罗地亚、美国排在前4名,中国队的防守RSR值为0.35,列所有参赛球队的第11名。攻防综合方面,美国、西班牙、澳大利亚是表现最为出色的球队,中国男篮的攻防RSR值为0.13,在所有参赛球队中垫底。本届奥运会形成了美国男篮实力出众、欧洲球队整体实力强劲、大洋洲和非洲篮球进步明显、亚洲篮球远远落后于世界篮球的新格局。  相似文献

我国优秀48kg女子摔跤运动员孙亚楠里约奥运会赛前训练特征研究     

白银川  刘卫军  许奎元  张莉清  赵林林  路海 《北京体育大学学报》2017,40(9):105-111

摘要：运用文献资料法、专家访谈法、数理统计法、实地跟踪法和指标测试法，对我国优秀48 kg女子摔跤运动员孙亚楠备战里约奥运会期间的训练时间、训练阶段划分、训练内容和方法、训练负荷和部分生理生化指标进行分析和研究，结果显示:1)赛前训练时间为10周，强化9周,调整1周；训练内容主要为体能和技战术，体能课77次,占46.7%，技战术课88次，占53.3%；训练方法体能主要以重复和循环训练法，技战术主要以完整训练法和模拟比赛法；负荷安排节奏性强且呈波浪型趋势；CK、BUN与血乳酸最大浓度值均表明达到了赛前理想状态。2)孙亚楠赛前第2周、第3周和第4周前半段CK和BUN数值呈现出居高不下的态势，身体仍存在疲劳，未能适应周训练强度的安排。结论:1）孙亚楠赛前训练安排较为合理，完成了赛前既定的目标与任务；2）赛前第2周、第3周和第4周前半段实际训练效果不佳，机体未能适应训练强度安排，可能与赛前训练内容中有氧和无氧训练比例的安排、赛前训练方法中有氧和无氧能力训练强度的控制有关。  相似文献   

Kinship,Camaraderie and Contestation: Fāṭimid Relations with the Ashrāf in the Fourth/Tenth Century.     

Shainool Jiwa 《Al-Masaq: Islam & the Medieval Mediterranean》2016,28(3):242-264

The founding of the Fā?imid caliphate across the southern Mediterranean, and then in Egypt, Syria and the ?ijāz at the turn of the fourth/tenth century, necessitated its negotiation with the ashrāf, those who claimed lineal descent from the Prophet Mu?ammad, and who by this time had gained significant influence as a social class based on their charismatic descent. While other dynastic powers fostered relationships with various members of the ashrāf, the Fā?imid–ashrāf dynamics were distinctive in that the Fā?imids legitimised their rule as Ismā?īlī Shī?ī imām-caliphs, based on their claim of descent from the Prophet Mu?ammad, and as the sole successors to his authority and leadership over the Islamic world. Consequently, Fā?imid–ashrāf relations were permeated by fraternal camaraderie as well as by competing contestations based on their shared claim to Prophetic lineage.  相似文献   

Press Credentials and Hybrid Boundary Zones: The Case of WorldNetDaily and the Standing Committee of Correspondents     

Jordan M. Foley 《Journalism Practice》2020,14(8):933-953

ABSTRACT

Press credentialing practices are a vital, yet understudied site of scholarly research on journalistic norms and practices. Press credentialing not only structures internal professional hierarchies, but they also signify the boundaries of the journalistic field itself. This paper explores the legal and theoretical implications of press credentialing to cover the United States Congress, drawing on the concepts of boundary work and journalistic authority to demonstrate the material impact of the space between fields on professional legitimation in journalism. Using WorldNetDaily (WND) as a case study, I argue that the Standing Committee of Correspondents (SCC) occupies a hybrid boundary zone between the journalistic and political fields, generating a unique tension in First Amendment jurisprudence that places journalists in a paradoxical role as both the professional embodiments of free speech and its constitutional steward. The resulting jurisdictional conflict between the SCC and WND extends the relational model of journalistic authority by articulating how journalist-state relations can fundamentally augment the process of legitimation at its fuzzy boundaries. The relevance and implications for press credentialing practices in the digital age are discussed.  相似文献   

传导系统中TE/TM偏振模态的辨析     

董国艳  史祎诗  王雅丽 《中国科学院大学学报》2016,33(3):347-353

电磁波/光传输特性研究中常用TE/TM偏振描述波的传播模式.不同系统中对TE/TM偏振的定义却存在差别,有时还与s/p态混合使用,使研究者在理论和实验研究中产生概念混淆和结果矛盾的问题.本文从电磁理论出发,对传导系统中可能存在的偏振模式进行深入的推导和分析,解释TE/TM偏振态存在原因和可能状态,对其与s/p态的区别进行比较说明.针对空间偏振态的易混淆问题进行逐一解答.  相似文献

Mapping migrant vernacular discourses: Mestiza consciousness,nomad thought,and Latina/o/x migrant movement politics in the United States     

Michael Lechuga 《Journal of International and Intercultural Communication》2020,13(3):257-273

ABSTRACT

This essay reads the Latina/o/x migrant vernacular discourses that emerge out of pro-migrant activism. Anzaldúa’s notion of mestizaje – a logic of border consciousness – is put into conversation with Deleuze’s notion of nomad thought – a logic of movement – to inform a rhetorical strategy for reading the vernacular archive of social movement discourse. The “No Papers, No Fear” is one such social movement that demonstrate the logic of mestizaje/nomadism in their communication strategies. This study illuminates three tensions that define the ways Latina/o/x migrants in the US navigate the spaces of citizenship: tensions between movement/stasis, migrant identity/national identity, and fear/safety.  相似文献   

不同古典医学文化中的“运动是良医”思想     

李文川  刘春梅 《北京体育大学学报》2017,40(8):133-140

摘要：慢性疾病成为新世纪重要的致死风险因素，而身体活动不足成为引发慢性疾病的重要原因。2007年，由ACSM（American College of Sports Medicine）、AMA（American Medical Association）发起“运动是良医”的全球行动至今已有39个国家加入。主要采用文献资料法，梳理古典医学文化时期中“运动是良医”思想的源起。研究发现，早在公元前的古希腊、古代罗马、古代印度以及古代中国古典医学文化时期的医学典籍中就出现了“运动是良医”的思想和实践，Herodicus、Hippocrates、Galen、Susruta、华佗等对这一思想的发展做出了重要的贡献。虽然东西方医学与锻炼的结合具有同源异流、动静相宜等差异，但对于锻炼对疾病的预防和治疗的价值认识是一致的。甚至于早在古典医学文化时期就开始了身体锻炼与肥胖、糖尿病等疾病治疗的实践，并从自然、人体、锻炼、饮食等因素对疾病和健康有了整体的认识。文艺复兴后，由于医学技术的高速发展，“体”“医”开始分道扬镳，今天，体医结合重新受到医学和体育领域的重视，通过文献分析使我们对“运动是良医”这一古老的思想有更加深刻的认识。  相似文献
