Philip A. E. Brey 《Ethics and Information Technology》2012,14(4):305-317
In this essay, a new approach to the ethics of emerging information technology will be presented, called anticipatory technology ethics (ATE). The ethics of emerging technology is the study of ethical issues at the R&D and introduction stage of technology development through anticipation of possible future devices, applications, and social consequences. In the essay, I will first locate emerging technology in the technology development cycle, after which I will consider ethical approaches to emerging technologies, as well as obstacles in developing such approaches. I will argue that any sound approach must centrally include futures studies of technology. I then present ATE and some applications of it to emerging information technologies. In ATE, ethical analysis is performed at three levels, the technology, artifact and application levels, and at each levels distinct types of ethical questions are asked. ATE analyses result in the identification and evaluation of a broad range of ethical issues that can be anticipated in relation to an emerging information technology. This ethical analysis can then be used for ethical recommendations for design or governance. 相似文献

Automatic measurement of key ski jumping phases and temporal events with a wearable system 总被引:1,自引:0,他引:1

We propose a new method, based on inertial sensors, to automatically measure at high frequency the durations of the main phases of ski jumping (i.e. take-off release, take-off, and early flight). The kinematics of the ski jumping movement were recorded by four inertial sensors, attached to the thigh and shank of junior athletes, for 40 jumps performed during indoor conditions and 36 jumps in field conditions. An algorithm was designed to detect temporal events from the recorded signals and to estimate the duration of each phase. These durations were evaluated against a reference camera-based motion capture system and by trainers conducting video observations. The precision for the take-off release and take-off durations (indoor < 39 ms, outdoor = 27 ms) can be considered technically valid for performance assessment. The errors for early flight duration (indoor = 22 ms, outdoor = 119 ms) were comparable to the trainers' variability and should be interpreted with caution. No significant changes in the error were noted between indoor and outdoor conditions, and individual jumping technique did not influence the error of take-off release and take-off. Therefore, the proposed system can provide valuable information for performance evaluation of ski jumpers during training sessions. 相似文献

Abstract To investigate the effects of ageing on the neural control strategies governing sprint cycling on a friction-loaded cycle-ergometer, 10 older (aged 70-83yr) and 8 young (aged 19-35yr) healthy women completed seven 6-s all-out cycling trials against varying loads. Root mean square (RMS), median frequency and muscle fibre conduction velocity were determined from the vastus lateralis of the dominant limb during each pedal stroke. Peak power was 43% lower in the older group compared to the younger (p?0.001) and was accompanied by a significantly lower RMS (p?0.05). No differences were observed in the other electromyography (EMG) parameters between the groups (p?>?0.05). ΔRMS from the first to the sixth second during each trial was found to increase significantly with the development of power output in both groups (p?0.05). For the first time during an all-out 6-s cycle trial, it has been demonstrated that older women's lower mechanical power output was accompanied by a significantly lower RMS, which indicates a decline in either the number of active of motor units or a reduced discharge rate. Hence, changes in motor units can be regarded as a contributory factor to the decline of muscle power with advancing age. Overall, though, similar neural strategies are adopted in both younger and older populations. 相似文献

Recently Australia has witnessed a revival of concern about the place of Australian literature within the school curriculum. This has occurred within a policy environment where there is increasing emphasis on Australia’s place in a world economy, and on the need to encourage young people to think of themselves in a global context. These dimensions are reflected in the recently published Australian Curriculum: English, which requires students to read texts of ‘enduring artistic and cultural value’ that are drawn from ‘world and Australian literature’. No indication, however, is given as to how the reading and literary interpretation that students do might meaningfully be framed by such categories. This essay asks: what saliences do the categories of the ‘local’, the ‘national’ and the ‘global’ have when young people engage with literary texts? How does this impact on teachers’ and students’ interpretative approaches to literature? What place does a ‘literary’ education, whether conceived in ‘local’, ‘national’ or ‘global’ terms, have in the twenty-first century? 相似文献

This paper discusses a strategy for accelerating the development of a regionally grounded knowledge base on educational leadership and management in East Asia. The study reviews data on patterns of knowledge production in East Asia, and employs the findings in the development of a strategy for increasing knowledge production. The study concludes that a suitable coordination strategy for the region should incorporate formal and informal strategies, be intermediate in scale and organised around a common research agenda. The authors propose that the substantive findings and the method of strategy analysis may also be relevant for academic leaders in other developing regions of the world. 相似文献
