高校女子400m跨栏运动员栏间节奏的探讨     

庄明谦  杨磊 《体育科技》2001,22(1):21-23

400m栏比赛的全程是由各个不同技术特征的若干段落所组成,通常把400m栏划分为五个阶段出发段、前程跨栏跑段、中程跨栏跑段、后程跨栏跑段和终点冲刺段.400m栏是人体极限运动项目之一,400m栏的关键是每一个栏周期的平均速度的平稳性,全程的速度分配、各栏间速度的发挥和利用程度,而保持速度的关键是栏间跑节奏的掌握.栏间步数、步长和节奏在400m栏中显得非常重要.  相似文献

Disciplinary containment: whiteness and the academic scarcity narrative     

Lisa A. Flores  Logan Rae Gomez 《传播与批判/文化研究》2020,17(2):236-242

ABSTRACT

Amid rising controversy around the alleged distinctions between merit and excellence lies a familiar refrain, scarcity. The narrative of academic scarcity, proclaiming the insufficient numbers of scholars and academics of color, permeates conversations in higher education. We suggest that the academic scarcity narrative, a remnant of stagnant logics of diversity, circulates as a contemporary mechanism of what we name disciplinary containment. Extending disciplinary conversations around rhetorical containment, we argue that disciplinary containment perpetuates whiteness.  相似文献   

On the elephant in the room: toward a generative politics of place on race in academic discourse     

Baudelaire Ulysse  Theodorea Regina Berry 《International journal of qualitative studies in education》2016,29(8):989-1001

Abstract

In our conceptual essay, we draw on an exchange between a White scholar and a group of panelists on Critical Race Theory at an international conference. Taking up this exchange as our point of departure, we work in dialectical and multidimensional ways between the essentialized politics of place on race and critical anti-essentializing foundations in recent Critical Race Feminism and Critical White Studies’ literatures. Working the dialectics and multidimensionality of the place that race makes in academic discourse, we recognize and ethically work through the essentialized politics of place in advancing anti-essentializing understandings of race. In articulating these anti-essentializing understandings, our conceptual essay drives at the notion of a generative politics of place on race in academic discourse. A generative politics of place holds essentialized realities and anti-essentializing foundations of race in dialectical and multidimensional tension for teaching, learning, and discussing race in local, national, and international contexts.  相似文献

#OscarsSoWhite: how Stuart Hall explains why nothing changes in Hollywood and everything is changing     

Isabel Molina-Guzmán 《Critical Studies in Media Communication》2016,33(5):438-454

ABSTRACT

Stuart Hall’s work on culture, representation, ideology and hegemony positions Hollywood as a cultural institution informed by and informative of US social values and norms. Thus contemporary debates over Hollywood's diversity are indicative of broader social conflicts. Empirically the article examines 2014–2015 news coverage of Hollywood to question the Hollywood paradox—the lack of diversity in film/TV production yet TV’s increasing shift towards on-screen diversity. It maps three discursive frames: Hollywood exceptionalism, economic imperatives, and institutionalized racism and sexism. The article concludes by using Hulu’s East Los High to reflect on TV’s digital turn and innovative models in production and representation.  相似文献   

The legend of Texas Western: journalism and the epic sports spectacle that wasn’t     

Phillip Hutchison 《Critical Studies in Media Communication》2016,33(2):154-167

This essay interrogates journalistic accounts of Texas Western College’s 1966 college basketball championship, a game in which an all-Black team defeated an all-White team. The analysis traces the evolving portrayals of the game over 45 years. In 1966 American journalists did not emphasize the racial aspects of the game and it was largely forgotten. Twenty-five years later, however, journalists reconstructed the game as a racialized legend, and this account evolved into an epic American narrative. The author argues that the epic portrayals, although aesthetically appealing, reflect problems with accuracy, appropriation, and commercial exploitation. The latter factor led to the legend’s motion picture adaptation as part of a troublesome “White Savior” cinema genre.  相似文献

Voices of teacher candidates of color on white race evasion: ‘I worried about my safety!’     

Yukari Takimoto Amos 《International journal of qualitative studies in education》2016,29(8):1002-1015

Abstract

This qualitative study investigated the negative impacts minority teacher candidates receive from white teacher candidates in a required multicultural education class. The findings reveal that four teacher candidates of color had difficulty positioning themselves among the overwhelming silencing power of whiteness in the class. The white students were tactful at evading power and race and flattening the existing hierarchical power relations through the discourses of colorblindness and by preying on the minority instructor. Their understanding of diversity was also shallow. On the other hand, the teacher candidates of color were afraid that they might be labeled as the ones who spoke up against the white students and fearful of the possibility of retaliation and ostracism from the white peers. It seems that the teacher education program’s structure allowed the white candidates to impose strong negative peer pressure on the teacher candidates of color.  相似文献
