在全国上下都高度重视安全生产的形势下,在企业都把安全管理放在一切工作首位的情况下,企业为什么还时有事故发生呢？现就企业如何预防和减少事故发生,努力杜绝事故发生做一些肤浅的探讨。举贤任能人,隐患无处藏企业中任何事故的发生,都有其深层次原因。安全知识告诉我们,人的不安全行为、物（设备）的不安全状态、环境的不安全因素。是企业事故发生的主要原因。 相似文献

德国的亚琛大剧院徐徐拉开了帷幕：
细雨霏霏,溪流汩汩。身着土染对襟布衫、头戴斗笠的“妻”跪蹲水边洗衣。捶,搓,绞。她甩几下水淋淋的木杵放入竹篮,沿石阶回篱合茅屋……在一束惨淡的顶光照射下,她美丽的脸埋在阴影里。水墨画般朦胧的乡村,沉郁的氖围,幽怨的音乐。甬剧《典妻》戏开场,就给了观众一种视觉的震撼。 相似文献

Restoring the spans of a historic bridge requires installing tensors to ensure the structural and mechanical stability of the rows of stones that form the resistant body of the bridge. Once the positions where the structure-crossing tensors should be installed have been determined, the entry and exit points of each drill hole must be marked on both sides of the bridge. However, the exit point of each drill hole is not visible from the entry point, making it impossible to drill precisely. Here, we present a method based on a calibrated system that combines precision topography with laser technology. Using this method, drill holes longer than 12 m can be achieved with centimetric precision. 相似文献

Abstract There are two starting points from which this paper is constructed: first, Virilio’s observation that the wealth of societies is founded on their dromocratic condition, that the faster societies accelerate their citizens, commercial goods and communication the more political and economic power they have and, second, the links that he traces between technologies of speed and acceleration and the accident. We suggest that Virilio’s ideas on this invite and deserve a closer ethnographic scrutiny than they have so far received, scrutiny that highlights the varied ways in which speed, acceleration and the accident are articulated in different cultural contexts. To this end we offer an investigation into the dromocratic condition, the violence of speed and the uses of accidents in Iceland. 相似文献

Abstract This study examines the contested space of environmental inequity and demonstrates how engaged intercultural communication research can be used to put forth seldom heard cultural environmental meaning systems. In an attempt to bridge ecojustice–environmentalist divides, we use Latino Critical Race Theory (LatCrit) to understand and promote practices of Hispanic communities enacting environmental justice and cultural activism. We also exemplify the value of an explicit focus on the role of race in environmental issues for communication scholarship. 相似文献

The Fukushima accident was a crisis in Japan, and a crisis elsewhere. In Europe, the aftermath of Fukushima was a period of intense questioning, about how to ensure the safety of nuclear reactors, and how, at the same time, ensure the ability of the European Union to act as a consistent political actor in the face of potentially catastrophic risks. Using empirical material related to the post-Fukushima stress tests and the subsequent discussions about the European regulatory framework for nuclear safety, this paper shows that stress tests have provided a peculiar form of European intervention, restabilizing regulatory boundaries while extending the European gaze. It describes the overall operation thereby performed as the “normalization of the crisis” whereby the exceptional situation enters the realm of the normal functioning of the public administrations, and where the actions undertaken take the form of the legal norm.

This essay charts the evolution of colportage in Walter Benjamin's body of writing. Originally referring to a form of popular literature peddled by travelling salesmen, Benjamin morphed the term into the ‘colportage phenomenon of space’, where he endowed it with a more abstract connotation referring to a form of embodied perception that could bridge distinctions between near and far and past and present, giving one access to ‘the whole of world history’. By holding a magnifying glass to this term, this essay elucidates the relevance of colportage in its historical context and unpacks its manifestations in Benjamin's essays, with iterations that often confuse boundaries between the material and the phenomenological. This essay further clarifies how Benjamin's handling of colportage exists alongside his studies of surrealism and his explorations into experience in modernity. 相似文献

The ambiguous material identity of nanotechnology is a minor mystery of the history of contemporary science. This paper argues that nanotechnology functioned primarily in discourses of social, not physical or biological science, the problematic knowledge at stake concerning the economic value of state-supported basic science. The politics of taxonomy in the United States Department of Energy’s Office of Basic Energy Sciences in the 1990s reveals how scientists invoked the term as one of several competing and equally valid candidates for reframing materials sciences in ways believed consonant with the political tenor of the time. The resulting loss of conceptual clarity in the sociology of science traces ultimately to the struggle to bridge the disjunction between the promissory economy of federal basic science and the industrial economy, manifested in attempts to reconcile the precepts of linearity and interdisciplinarity in changing socio-economic conditions over a half century. 相似文献
