The worlds of the living and the dead might seem irrevocably cut off from one another. Nevertheless, an important strand of modern thought attempts to find some form of intelligibility emanating from the dead. Paul de Man's discussion of prosopopoeia suggests the possibility of giving voice to the dead, though this turns out to be a form of delusion inherent in language. Emmanuel Levinas, arguing against Heidegger, seeks to maintain a relationship with the other beyond death, and Giorgio Agamben tries to find meaning in the silent testimony of victims of the Holocaust. This article examines these various attempts to mediate with the dead and suggests that it may be impossible to eliminate the risk of imposing our own words on those who cannot speak. However, a readiness to be surprised by unanticipated meanings may be the necessary condition to finding signifying sources outside ourselves. 相似文献

This article addresses the question of whetherpersonal surveillance on the world wide web isdifferent in nature and intensity from that inthe offline world. The article presents aprofile of the ways in which privacy problemswere framed and addressed in the 1970s and1990s. Based on an analysis of privacy newsstories from 1999–2000, it then presents atypology of the kinds of surveillance practicesthat have emerged as a result of Internetcommunications. Five practices are discussedand illustrated: surveillance by glitch,surveillance by default, surveillance bydesign, surveillance by possession, andsurveillance by subject. The article offerssome tentative conclusions about theprogressive latency of tracking devices, aboutthe complexity created by multi-sourcing, aboutthe robustness of clickstream data, and aboutthe erosion of the distinction between themonitor and the monitored. These trendsemphasize the need to reject analysis thatframes our understanding of Internetsurveillance in terms of its impact onsociety. Rather the Internet should beregarded as a form of life whose evolvingstructure becomes embedded in humanconsciousness and social practice, and whosearchitecture embodies an inherent valence thatis gradually shifting away from the assumptionsof anonymity upon which the Internet wasoriginally designed. 相似文献

The production of anatomical teaching resources using three‐dimensional (3D) printing technology 下载免费PDF全文
Paul G. McMenamin Michelle R. Quayle Colin R. McHenry Justin W. Adams 《Anatomical sciences education》2014,7(6):479-486
The teaching of anatomy has consistently been the subject of societal controversy, especially in the context of employing cadaveric materials in professional medical and allied health professional training. The reduction in dissection‐based teaching in medical and allied health professional training programs has been in part due to the financial considerations involved in maintaining bequest programs, accessing human cadavers and concerns with health and safety considerations for students and staff exposed to formalin‐containing embalming fluids. This report details how additive manufacturing or three‐dimensional (3D) printing allows the creation of reproductions of prosected human cadaver and other anatomical specimens that obviates many of the above issues. These 3D prints are high resolution, accurate color reproductions of prosections based on data acquired by surface scanning or CT imaging. The application of 3D printing to produce models of negative spaces, contrast CT radiographic data using segmentation software is illustrated. The accuracy of printed specimens is compared with original specimens. This alternative approach to producing anatomically accurate reproductions offers many advantages over plastination as it allows rapid production of multiple copies of any dissected specimen, at any size scale and should be suitable for any teaching facility in any country, thereby avoiding some of the cultural and ethical issues associated with cadaver specimens either in an embalmed or plastinated form.

Absract Our understanding of the relationship between physical activity and health is constantly evolving. Therefore, the British Association of Sport and Exercise Sciences convened a panel of experts to review the literature and produce guidelines that health professionals might use. In the ABC of Physical Activity for Health, A is for All healthy adults, B is for Beginners, and C is for Conditioned individuals. All healthy adults aged 18–65 years should aim to take part in at least 150 min of moderate-intensity aerobic activity each week, or at least 75 min of vigorous-intensity aerobic activity per week, or equivalent combinations of moderate- and vigorous-intensity activities. Moderate-intensity activities are those in which heart rate and breathing are raised, but it is possible to speak comfortably. Vigorous-intensity activities are those in which heart rate is higher, breathing is heavier, and conversation is harder. Aerobic activities should be undertaken in bouts of at least 10 min and, ideally, should be performed on five or more days a week. All healthy adults should also perform muscle-strengthening activities on two or more days a week. Weight training, circuit classes, yoga, and other muscle-strengthening activities offer additional health benefits and may help older adults to maintain physical independence. Beginners should work steadily towards meeting the physical activity levels recommended for all healthy adults. Even small increases in activity will bring some health benefits in the early stages and it is important to set achievable goals that provide success, build confidence, and increase motivation. For example, a beginner might be asked to walk an extra 10 min every other day for several weeks to slowly reach the recommended levels of activity for all healthy adults. It is also critical that beginners find activities they enjoy and gain support in becoming more active from family and friends. Conditioned individuals who have met the physical activity levels recommended for all healthy adults for at least 6 months may obtain additional health benefits by engaging in 300 min or more of moderate-intensity aerobic activity per week, or 150 min or more of vigorous-intensity aerobic activity each week, or equivalent combinations of moderate- and vigorous-intensity aerobic activities. Adults who find it difficult to maintain a normal weight and adults with increased risk of cardiovascular disease or type 2 diabetes may in particular benefit from going beyond the levels of activity recommended for all healthy adults and gradually progressing towards meeting the recommendations for conditioned individuals. Physical activity is beneficial to health with or without weight loss, but adults who find it difficult to maintain a normal weight should probably be encouraged to reduce energy intake and minimize time spent in sedentary behaviours to prevent further weight gain. Children and young people aged 5–16 years should accumulate at least 60 min of moderate-to-vigorous-intensity aerobic activity per day, including vigorous-intensity aerobic activities that improve bone density and muscle strength. 相似文献

Abstract The aim of this study was to compare the incidence, nature, and cause of injuries sustained in rugby union played on artificial turf and grass. The study comprised a two-season investigation of match injuries sustained by six teams competing in Hong Kong's Division 1 and training injuries sustained by two teams in the English Premiership. Injury definitions and recording procedures were compliant with the international consensus statement on epidemiological studies of injuries in rugby union. There were no significant differences in the overall incidence (rate ratio = 1.42; P = 0.134) or severity (P = 0.620) of match injuries sustained on the two surfaces. The lower limb and joint (non-bone)/ligament injuries were the most common location and type of match injury on both surfaces; the incidence of anterior cruciate ligament injuries was nearly four times higher on artificial turf than grass but the difference was not statistically significant (rate ratio = 3.82; P = 0.222). There were no significant differences in the overall incidence (rate ratio = 1.36; P = 0.204) or severity (P = 0.302) of training injuries sustained on artificial turf and grass. The lower limb and muscle/tendon injuries were the most common location and type of training injury on both surfaces. The results indicate that the overall risks of injury on artificial turf are not significantly different from those experienced on grass; however, the difference in the incidence of anterior cruciate ligament injuries on the two surfaces is worthy of further study. 相似文献
