The ethics of aesthetics: Stigma,information, and the politics of electronic ankle monitor design     

Lauren Kilgour 《The Information Society》2020,36(3):131-146

Abstract

At present, the politics of digital tools are predominantly discussed in terms of the data they collect, analyze, and circulate. Through my analysis of electronic ankle monitors’ visual characteristics, I widen the scope of investigation to consider how the visuality of digital tools’ form factor – the size and shape of computing hardware – also contributes to their politics. I discuss five major impacts the visuality of electronic ankle monitors’ physical form has upon their wearers’ lives: (1) lack of differentiation in the aesthetics of monitors across different types of wearers (spanning from criminal justice to immigration detention) leads wearers to be considered “dangerous criminals,” by default; (2) monitors limit wearers’ ability to “pass” in society; (3) monitors expand the set of surveillors beyond government officials to also include the public; (4) monitors compromise wearers’ privacy; (5) monitors associate wearers with older practices of visually marking people normative society has labeled dangerous. Based on this analysis, I argue two points. First, that the visuality of electronic ankle monitors’ form factor expands the harms wearers experience beyond those engendered by the device’s primary use as a remote geo-temporal tracking tool used by government organizations. Second, the case study of electronic ankle monitors evidences the need to develop laws and policies that seek to regulate the visual properties of digital tools as well as the data they generate.  相似文献

沙滩排球训练对运动员膝,踝关节肌群肌力影响的比较研究   总被引：1，自引：0，他引：1  

徐国红  葛春林  尹洪满 《体育学刊》2000,(6):42-45

为探讨沙滩排球训练对运动员膝、踝关节肌群肌力的影响,沙滩排球训练周期前后,对我国１２名兼职沙滩女排运动员的膝、踝关节肌群进行了ＢＩＯＤＥＸ肌力测试。结果表明,沙滩训练后,膝关节屈肌群快肌纤维的爆发力,伸肌群快肌纤维的最大力和爆发力,踝关节跖肌群慢、快肌纤维的最大肌力和爆发力增长有显性意义,这是沙滩训练后原地纵跳成绩提高的重的肌力原因。  相似文献   

What goes up must come down: Consequences of jump strategy modification on dance leap take-off biomechanics     

Danielle N. Jarvis  Kornelia Kulig 《Journal of sports sciences》2020,38(16):1836-1843

ABSTRACT

Chronic foot and ankle injuries are common in dancers; understanding how lower extremity loading changes in response to altered task goals can be beneficial for rehabilitation and injury prevention strategies. The purpose of this study was to examine mechanical demands during jump take-offs when the task goal was modified to focus on either increasing jump distance or increasing jump height. It was hypothesized that a jump strategy focused on height would result in decreased energetic demands on the foot and ankle joints. Thirty healthy, experienced female dancers performed saut de chat leaps while travelling as far as possible (FAR) or jumping as high as possible (UP). Ground reaction force (GRF) impulses and peak sagittal plane net joint moments and sagittal plane mechanical energy expenditure (MEE) of the metatarsophalangeal (MTP), ankle, knee, and hip joints were calculated. During take-off, vertical and horizontal braking GRF impulses were greater and horizontal propulsive GRF impulse was lower in the UP condition. MEE at the MTP, ankle, and hip joints was lower in UP, and MEE at the knee was higher in UP. These results suggest that a strategy focused on height may be helpful in unloading the ankle and MTP joints during dance leaps.  相似文献

局部肌肉疲劳对踝关节本体感觉的影响   总被引：1，自引：0，他引：1  

张秋霞  张林  王国祥 《体育科学》2011,31(3):68-73,80

目的:通过分析局部肌肉疲劳前、后踝关节在矢状面内运动的位置觉、肌肉力觉的变化,探讨局部肌肉疲劳对踝关节本体感觉的影响,为踝关节损伤防治和康复训练提供基础理论和实验依据。方法:选取14名无踝关节疾患的受试者为实验对象,踝关节位置觉采用对踝关节跖屈5°的被动定位、被动复位能力进行测试,肌肉力觉采用受试者踝关节对跖屈肌群25%最大等长峰值力矩值的复制能力进行测试;疲劳测试采用60最大等速向心运动模式;对于局部肌肉疲劳前、后踝关节本体感觉的对比,采用重复测量方差分析进行。结果:踝关节的位置觉(VEJPS和AEJPS)和肌肉力觉(RVEFS和RAEFS)在局部肌肉疲劳前、后的差异均有统计学意义(P<0.05)。结论:1)最大等速向心运动至局部肌肉疲劳后,踝关节的位置觉均较疲劳前下降;2)最大等速向心运动至局部肌肉疲劳后,踝关节的肌肉力觉均较疲劳前下降;3)踝关节最大等速向心运动至局部肌肉疲劳后,受试者的中枢控制策略发生改变。  相似文献
