Do stiffness and asymmetries predict change of direction performance?

Change of direction speed (CODS) underpins performance in a wide range of sports but little is known about how stiffness and asymmetries affect CODS. Eighteen healthy males performed unilateral drop jumps to determine vertical, ankle, knee and hip stiffness, and a CODS test to evaluate left and right leg cutting performance during which ground reaction force data were sampled. A step-wise regression analysis was performed to ascertain the determinants of CODS time. A two-variable regression model explained 63% (R² = 0.63; P = 0.001) of CODS performance. The model included the mean vertical stiffness and jump height asymmetry determined during the drop jump. Faster athletes (n = 9) exhibited greater vertical stiffness (F = 12.40; P = 0.001) and less asymmetry in drop jump height (F = 6.02; P = 0.026) than slower athletes (n = 9); effect sizes were both “large” in magnitude. Results suggest that overall vertical stiffness and drop jump height asymmetry are the strongest predictors of CODS in a healthy, non-athletic population.     

Mental illness,late capitalism,and the socioeconomic “psychopath” in CBS’s Elementary

This article focuses on representations of mental illness on U.S. network television, particularly the “police procedural” Elementary. As a modern interpretation of the Sherlock Holmes character, Elementary is unique in emphasizing the detective’s struggles with drug addiction and mental illness, as well as a long road of recovery where intellectual labor is instrumental and “therapeutic” (rather than stressful and alienating). Despite its critical acclaim, Elementary’s progressive portrayals of symptoms of mental illness in Holmes are complicated by the series’s stereotypical depiction of villains that are “mad men,” “lunatics,” and “psychopaths” driven by financial gain and individual greed. The “acceptability” of mental illness in the series is measured by a character’s compliance with the dominant social order. While Elementary provides some positive messages about mental illness, its socioeconomic commentaries individualize “madness,” violence, and the pitfalls of late capitalism to support an increasingly problematic narrative of neoliberalism and mental health.     

Bandung Lautan Hardcore: territorialisation and deterritorialisation in an Indonesian hardcore punk scene

Abstract

This article explores the entangled and contradictory processes of territorialisation and deterritorialisation that have shaped the hardcore punk scene in Bandung, Indonesia, while questioning the binary model of globalisation and localisation. The formation of the Bandung scene has certainly involved processes of local adaptation, translation, and territorialisation, but these cannot be disentangled from the global styles, orientations, and networks associated with hardcore punk. Through their active participation in global hardcore, Bandung's punks adopt a standpoint of underground cosmopolitanism that goes beyond a merely mimetic relationship to Western scenes. Their valorisation of local “Do It Yourself” production and performance reflects the value practices of global hardcore punk, and the social relationships that constitute the local scene extend beyond any straightforwardly spatial definition of the “local.” At the same time, this global orientation takes on particular locally-inflected meanings in the specific cultural and political environment of Bandung, Indonesia.     

Prior workload has moderate effects on high-intensity match performance in elite-level professional football players when controlling for situational and contextual variables

ABSTRACT

This investigation examined the effect of prior workload on high-intensity football match performance. Player load variables were recorded using a global positioning system and converted into composite variables: rolling season accumulated load (AL), exponentially weighted moving average acute, chronic and acute:chronic workload ratio (A:C). Match-play high-intensity performance-per-minute: accelerations (ACC), sprints, high-speed running (HSR) and high metabolic load (HMLd) distances; and situational and contextual variables were recorded for all games. Partial least squares modelling, and backward stepwise selection determined the most parsimonious model for each performance variable. Quadratic relationships of small to moderate effect sizes were identified for sprint AL and sprint performance, HSR AL and HSR performance, acute HMLd and HMLd performance, acute sprint load and ACC performance and A:C sprint load and ACC performance. Match performance was typically greatest between the mean and +1SD. High chronic HMLd, and combined acceleration and deceleration (ACC+DEC) load exerted small beneficial effects on HMLd and HSR performance, whereas high acute load exerted trivial to moderate negative effects. High sprint A:C exerted a small beneficial effect on sprint performance and playing position exerted small effects on HSR and HMLd performance. Prior workload has trivial to moderate effects on high-intensity match performance in professional players.     

Incorporating a new bioinformatics component into genetics at a historically black college: outcomes and lessons

Many students at minority-serving institutions are underexposed to Internet resources such as the human genome project, PubMed, NCBI databases, and other Web-based technologies because of a lack of financial resources. To change this, we designed and implemented a new bioinformatics component to supplement the undergraduate Genetics course at Clark Atlanta University. The outcomes of the Bioinformatics course were assessed. During the first week of the semester, students were assigned the Felder-Soloman's Index of Learning Styles Inventory. The overwhelming majority of students were visual (82.1%) and sequential (75.0%) learners. Furthermore, pre- and postcourse surveys were administered during the first and the last week of the course to assess learning, confidence level, and mental activity. These indicated students increased the number of hours spent using computers and doing homework. Students reported confidence in using computers to study genetics increased, enabling them to better visualize and understand genetics. Furthermore, students were more mentally engaged in a more social learning environment. Although the students appreciated the value of the bioinformatics component, they reported the additional work load was substantial enough to receive additional course credit.     

Library Student Employee Expertise: Strategies for Maximizing Your Student Employee Contributions to the Library

The University of Baltimore Library was recently renovated. Part of the design in the newly renovated space was having one single service point, that we call the Information Desk. This desk serves as the public facing portal for what was previously three public facing service points to services by three separate departments, Academic Success, Access Services and Reference & Instruction.

This article describes in depth how our Information Desk Leadership Team encouraged and used our library student employees’ expertise and knowledge in the formation of policy and procedure manual, training documents, reference tools and resume lines for use at a single service point.     

Being ‘at’ university: the social topologies of distance students

This paper considers how online, distance students enact the space of ‘the university’, in the context of the rise of distance education within a traditional, ‘elite’ institution. Aiming to provide insight into how students translate into distance the space of a university which has traditionally had its basis in conventional on-campus education, it locates itself within the ‘new mobilities’ paradigm (Urry in Mobilities. Polity Press, Cambridge, 2007), drawing on four different kinds of social space delineated by Mol and Law (Soc Stud Sci 24(4):641–741, 1994) and Law and Mol (Environ Plan D 19:609–621, 2001) in order to analyse narrative and visual data generated with distance students at the University of Edinburgh. The paper shows that the material campus continues to be symbolically and materially significant for a group of students who may never physically attend that campus. Distance students, we find, need their own version of the ‘spatial certainties’ of bounded, campus space. Yet, in exploring the ‘new proximities’ of online distance education, we also argue that to define institutional and academic authenticity solely in terms of this bounded, ‘regional’ space is inadequate in the face of the other topologies which also come into play throughout distance students’ accounts of what it means to be ‘at’ university.
