We live in a world increasingly photographed from satellites, planes, and drones. Many scholars have viewed aerial imagery through a dystopian lens, largely due to its use by the state and its legacy of military applications. While problematic uses of aerial images persist, this paper theorizes rhetorical potentialities of aerial imagery. We posit how aerial imagery creates these potentialities through strategies related to questions of visibility, scale, and aesthetics. Using case studies that illuminate these strategies, we demonstrate how they can be used to resist state and corporate interests, constitute new social movements, and invite contemplation of otherwise repellent political subject matter. Ultimately, we argue that with increased technological access and the ability to reconfigure norms of expertise, the aerial view presents both opportunities for civic engagement and counter-hegemonic potential. 相似文献

This study demonstrates how academicians and practitioners can work together on an important topic that matters to organizational performance: the pivotal role played by salespeople during new product launches. In particular, the authors present three potential interventions that training and sales managers may use to sell a new product to salespeople. The results legitimatize the critical contribution of sales training to new product sales performance and highlight the value of the partnership between training professionals and sales managers. 相似文献

后现代文化视野中的道德教育之审美维度 总被引:2,自引:0,他引:2
网络,也称互联网,它自1969年在美国问世以来,经过三十多年的发展,波及全球,渗透到人类政治、经济、文化等各大领域,迅速地改变了人们的学习、生活工作和思维方式。网络社会,各种思想意识形态冲破了时间、空间、国界的限制,以一种新的传播方式深刻地影响着人们的思想观念、道德风貌和价值取向。中国互联网络信息中心(CNNIC)2004年7月的《中国互联网络发展状况统计报告》显示,中国网民中18至30岁的网民数量占总数的53.2%,大专和本科文化层次的占54.2%。网络对大学生影响较大。积极方面:它有利于大学生效率观念、平权意识和全球眼光的形成;有利于大学生现代生活方式的形成; 相似文献

Exercise testing on motorised treadmills provides valuable information about running performance and metabolism; however, the impact of treadmill type on these tests has not been investigated. This study compared the energy demand of running on two laboratory treadmills: an HP Cosmos (C) and a Quinton (Q) model, with the latter having a 4.5 times stiffer running platform. Twelve experienced runners ran identical bouts on these treadmills at a range of four submaximal velocities (reported data is for the velocity that approximated 75–81% VO2max). The stiffer treadmill elicited higher oxygen consumption (C: 46.7 ± 3.8; Q: 50.1 ± 4.3 ml·kg?1 · min?1), energy expenditure (C: 16.0 ± 2.5; Q: 17.7 ± 2.9 kcal · min?1), carbohydrate oxidation (C: 9.6 ± 3.1; Q: 13.0 ± 3.9 kcal · min?1), heart rate (C: 155 ± 16; Q: 163 ± 16 beats · min?1) and rating of perceived exertion (C: 13.8 ± 1.2; Q: 14.7 ± 1.2), but lower fat oxidation (C: 6.4 ± 2.3; Q: 4.6 ± 2.5 kcal · min?1) (all analysis of variance treadmill comparisons P < 0.01). This study confirms that caution is required when comparing performance and metabolic results between different treadmills and suggests that treadmills will vary in their comparability to over-ground running depending on the running platform stiffness. 相似文献

My vision of Jewish education assumes the critical importance of finding not only better methodologies and curricula but also more highly motivated and better-trained staff. Yet, even with such an assumption, the ultimate need is for religious schools to “connect” in the deepest sense: to connect with the family as much as with the student; to connect with the students' perceptions of the world they know, so that Jewish learning does not seem to be totally alien to their lives; and to connect with a sense of the overall vibrancy of the synagogue as the center of Jewish life. 相似文献

This article explores how innovations in the funeral industry borrow from the technological affordances, commercial logics, cultural norms, and affective registers of social media platforms. Based on ethnographic research of funeral industry conventions, we analyze examples of funeral planning tools, funeral service mediation, and digital memorialization products. We consider how these products aim to capture forms of data, affect, and value as part of the funeral industry’s efforts to shore up their historically intermediary relevance in the face of potential “disruption” from technological innovation, and threats of marginalization posed by shifting norms of networked grieving and commemoration in digital culture 相似文献

The lives of Puerto Ricans in the neighborhood of Humboldt Park, Chicago, are often situated in a complex social field shaped by transnational cultural and political border crossing. We argue that artistic practices in this neighborhood are integral to building community and individual identities grounded in local meanings of the Puerto Rican diaspora experience. Interviews with three adolescent community residents and a high school art teacher indexed themes that exemplify community residents’ purposes for artistic practice: (1) self-expression within practices of collective identity building; (2) cultural reclamation; and (3) political reimagining. We also discuss how such work invites new tensions for identity making, including who can participate, who is represented, and what forms those representations take. These tensions point backward in time, forward to the future, and across geopolitical space. Finally, we suggest implications for learning in schools. 相似文献

Tin(Sn)-based perovskite solar cells(PSCs) have received increasing attention in the domain of photovoltaics due to their environmentally friendly nature.In this paper,numerical modeling and simulation of hole transport material(HTM)-free PSC based on methyl ammonium tin triiodide(CH3NH3SnI3) was performed using a one-dimensional solar cell capacitance simulator(SCAPS-1D) software.The effect of perovskite thickness,interface defect density,temperature,and electro... 相似文献
