This article reports the results and conclusions of a mixed-methods research strategy designed to assess the potential of community networking in rural Tamil Nadu, India. The data reported and analyzed in this article include socioeconomic and household spending, agricultural marketing and price search, availability and use of information on agricultural problems, and communication media use. We use these data to define a framework of existing sources of information for various community agents, with a special emphasis on farmers. We analyze the methods and costs at which these agents obtain information, and identify information and communication gaps that information and communication technologies (ICTs) may help alleviate. This study allows us to demonstrate opportunities for socioeconomic development through ICT-enabled information access. The article concludes by stating the importance of basic communication technologies and contextually relevant information services, and suggesting recommendations for future research in this area. 相似文献

Spatial injustices, especially the disproportionate exposure of disadvantaged communities to environmental risks, stem from an inability to appreciate the lived experience of risk and, instead, a reliance on technical frameworks for regulating it. We review Noddings’ ideas about the caring attitude, in particular, that of caring for and, to some degree, caring about, and apply this to the issue of knowing about the experience of vulnerability and crafting effective and affective responses to it. We apply this lens to the case study of Southeast Los Angeles, where a profusion of small sources of air toxics creates zones of inordinate risk, and ask: How should the state and community have responded in a more caring way? How could the teachers and schoolchildren, themselves, have been empowered to speak for themselves? We draw lessons from it that speak to how we can begin reforming the regulatory state. 相似文献

The aim of this study was to examine the performance characteristics of male and female finalists in the 100-m distance at the 2016 European Championships in swimming (long-course-metre). The performances of all 64 (32-males and 32-females) were analysed (8 swimmers per event; Freestyle, Backstroke, Breaststroke and Butterfly). A set of start and turn parameters were analysed. In the start main outcome, male swimmers were faster in Butterfly (5.71 ± 0.14s) and females in Freestyle (6.68 ± 0.28s). In the turn main outcome, male and female swimmers were faster in Freestyle (males: 9.55 ± 0.13s; females: 10.78 ± 0.28s). A significant and strong stroke effect was noted in the start and turn main outcome, in both sexes. In the start plus the turn combined, males and females were faster in Freestyle (males: 15.40 ± 0.20s; females: 17.45 ± 0.54s). The start and the turn combined accounted almost one-third of the total race time in all events, and non-significant differences (p > 0.05) were noted across the four swim strokes. Once this research made evident the high relevance of start and turns, it is suggested that coaches and swimmers should dedicate an expressive portion of the training perfecting these actions. 相似文献

The paper presents a stochastic calculations algorithm that mimics the photon polarization experiments of quantum mechanics. This experiment is usually used to introduce the quantum computing approach. Stochastic filters that operate on stochastic numbers in a mode similar to that of polarized filter operation on random polarized photons are introduced. 相似文献

User acceptance of a digital library system in developing countries: An application of the Technology Acceptance Model 总被引：1，自引：0，他引：1

This study examines the factors that influence people's adoption and use of a digital library system and tests the applicability of the Technology Acceptance Model (TAM) in the context of developing countries. Using data from a survey of 16 institutions in Africa, Asia, and Central/Latin America (N = 1082), a path analysis revealed that perceived ease of use of the library system had a significant impact on perceived usefulness, which ultimately led to behavioral intention to use. In addition, the study examined the similarities and differences in the significant predictors of the digital library acceptance across countries and continents. Further, the current study suggests that external variables that affect perceived ease of use and usefulness need to be considered as important factors in the process of designing, implementing, and operating digital library systems. Such consideration will help decrease the mismatch between system design and local users’ realities, and further facilitate the successful adoption of digital library systems in developing countries. 相似文献

Assuming that, given the processes of technology diffusion, adolescent behavior forecasts future consumption of digital information, it would seem pertinent to study the characteristics of teenager technology use. This research asks: What are the key patterns regarding the use of technology platforms by teenagers? Is technology usage among teenagers shaped by schools' disparate teaching philosophies and cultures? How is technology usage impacting the consumption of traditional print media? A survey designed to determine how high school students use technology was administered at a private boarding school in New Hampshire and a public school in New York. The research concluded that individuals' residing environment and context shape ICT adoption. School culture and geographic context drive behavioral technology usage patterns. Furthermore, consumption of information appears to be guided by a principle of complementarity. However, technology substitution should not be discarded. Finally, school culture incorporating and promoting technology use may contribute positively to knowledge acquisition, although technology adoption without controls could negatively impact the teaching experience. While directionally valid, the study results need to be validated by statistical research and case studies. 相似文献

The menstrual cycle (MC) phases carry to several psychophysiological alterations; however, no study has investigated the impact of MC phases on training load or technical training. In the present study, we investigated the effect of the follicular phase (FP), ovulatory phase (OP), and luteal phase (LP) on training load and technical training in young athletes. Twelve female athletes performed regular daily training sessions with the rating of perceived exertion (RPE) and duration being registered every session. Training impulse (TRIMP), monotony and strain were calculated. MC symptoms, RPE, and duration were also measured during technical training, which was carried out on a specific day during each phase. The TRIMP was not affected by MC phases during regular training (p > .05), but training monotony and strain were higher in FP compared to OP (p < .05). During the technical training, MC phases did not affect RPE (p > .05), but the session was longer in both FP and LP, compared to OP (p < .05). MC symptoms were exacerbated in FP compared to both OP and LP (p < .05). These findings suggest that MC disorders were elevated during FP, which indicate that monitoring MC phases might provide important feedbacks for programming training and expected results during competitions. 相似文献
