Technologies of Humility: Citizen Participation in Governing Science   总被引:5,自引:0,他引:5  
Jasanoff  Sheila 《Minerva》2003,41(3):223-244
Building on recent theories ofscience in society, such as that provided bythe `Mode 2' framework, this paper argues thatgovernments should reconsider existingrelations among decision-makers, experts, andcitizens in the management of technology.Policy-makers need a set of `technologies ofhumility' for systematically assessing theunknown and the uncertain. Appropriate focalpoints for such modest assessments are framing,vulnerability, distribution, and learning.  相似文献

The study explored the role of second-screen use and binge-watching in moderating entertainment education (EE) effects. A pretest/posttest experiment of 273 viewers of East Los High measured the effects of exposure to three subplots, concerning alcohol abuse, abortion, and immigration. The effect of identification with characters on change in attitudes was significantly moderated by second-screen use and binge-watching. In particular, second-screening tended to enhance the positive impact of identification; whereas, among respondents who binge-watched the show, the effects of identification were weaker.  相似文献

Disparities in the technology practices, skills and knowledge of school students still exist, despite widespread investment, and use in schools. In order to understand why inequalities remain, we first need a more nuanced understanding of students’ technology practice, including understanding how their backgrounds, circumstances and experiences shape their perceptions of and engagement with technology. This paper proposes that research in the field of educational technology would benefit from a sociological framing in order to highlight how and why students use technology at school and in their everyday lives. The paper reports on a qualitative embedded case study of 13–16-year-old students in two Australian secondary schools. In-depth case studies of two selected students illustrate the complex nature of students’ technology practice. Bourdieu’s concepts of field, habitus and capital are used as a lens through which to view and understand inequalities in students’ technology practice. The findings demonstrate the utility of sociological theory in educational technology research by highlighting systems and structures of reproduction and transformation. Furthermore, the findings can inform an approach to teaching and learning that considers students’ varied experiences, knowledge, perspectives and backgrounds relating to technology.  相似文献

This study examined the skill involvements of three positional groups across a junior representative rugby league season. Data were collected from 45 rugby league players (mean ± SD; age = 16.5 ± 1.0 years) currently participating in the Harold Matthews and SG Ball Cup. Players were subdivided into hit-up forwards, adjustables and outside backs. The frequency (n · min?1) of offensive, defensive and overall involvements was coded for each group using a notation system and a practical coach skill analysis tool. Multivariate analysis of variance (MANOVA) revealed a significant effect of playing position on skill involvements (F = 9.06; P < 0.001; ES = 0.41). Hit-up forwards performed a significantly greater frequency of offensive (0.31 ± 0.10), defensive (0.42 ± 0.15) and overall involvements (0.74 ± 0.19) when compared to adjustables (0.20 ± 0.08, 0.28 ± 0.08 and 0.52 ± 0.15, respectively) and outside backs (0.20 ± 0.12, 0.11 ± 0.07 and ± 0.31 ± 0.17, respectively). Further, adjustables performed a significantly greater number of defensive (0.28 ± 0.08) and overall involvements (0.52 ± 0.15) when compared to outside backs (0.11 ± 0.07 and 0.31 ± 0.17, respectively). The findings of this study suggest that it is important to consider a junior player’s positional group when analysing their skill involvements. Information gained from this study could assist in the design of specific training methodologies for junior rugby league players in high-level talent development programmes.  相似文献

Despite a substantial body of research suggesting genetic influence on educationally relevant behavioural traits, it is not clear how the nature–nurture question is perceived by teachers. In order to answer this question, we surveyed 667 UK primary school teachers, and for comparison also surveyed 1,340 parents about their perceptions of genetic and environmental influence on personality, intelligence, behaviour problems, learning difficulties, and mental illness. For these five domains of behaviour, the percentages of teachers who reported that genetics were at least as important as environment were .87, .94, .43, .94, and .91, respectively. Results for parents were similar (.92, .93, .54, .86, and .89). We also found that 80% of teachers reported no coverage of genetics during teacher training.  相似文献

ABSTRACT

Cities in the United States and across the world have experienced gentrification at the same time as school choice policies have become more popular. This research examines the relationship between gentrification and charter schooling, seeking to understand how together they affect demographic composition of schools across Washington, DC. This study uses geographic information systems (GIS) mapping and statistical techniques to show that gentrified neighborhoods are more likely to have charter schools. Additionally, the demographic compositions of charter schools and traditional public schools differ depending on the gentrification classification of the census tract in which the schools are located. While a handful of diverse charter schools exist in gentrified neighborhoods and some diverse public schools exist in traditionally affluent neighborhoods, schools in Washington, DC remain racially and economically isolated overall.  相似文献

After defining UNESCO's place in the United Nations system, the author outlines the new situation that has arisen in recent years for the world's children. Although infant mortality rates continue to give concern, the major problem that international organisations have now to face is not the question of children's survival but their development. Research shows that the vital age for developmental inputs is early childhood, without which the chances of later learning achievement are severely diminished. The proposed ECD Programming Model attempts to take into account present research on early child development as well as the socio‐economic context of developing countries, where governments are increasingly unable to provide basic services.  相似文献

The effects of identical context on pattern recognition by pigeons for outline drawings of faces were investigated by training pigeons to identify (Experiment 1) and categorize (Experiment 2) these stimuli according to the orientation of the mouth—an upright U shape representing a smiling mouth or an inverted U shape representing a sad mouth. These target stimuli were presented alone (Pair 1), with three dots in a triangular orientation to represent a nose and eyes (Pair 2), and with the face pattern surrounded by an oval (Pair 3). In Experiment 1, the pigeons trained with Pair 1 were most accurate, those trained with Pair 2 were less so, and those trained with Pair 3 failed to acquire the discrimination within eighty 100-trial sessions. The same ordering was found in Experiment 2 for pigeons trained on the three pairs simultaneously. The authors suggest that a contrasting finding in humans, the face superiority effect, might be due to a gain in discriminability resulting from recognition of the pattern as a face. An exemplar model of information processing that excludes linguistic coding accounts for the present results.  相似文献
