Individual behaviour change is fast becoming a kind of ‘holy grail’ to tackle climate change, in environmental policy, the environmental movement and academic literature. This is contested by those who claim that social structures are the main problem and who advocate collective social action. The objective of the research presented in this paper is to better understand why environmentally concerned citizens choose one of these two types of engagement. Our focus is on the role of experiences of and/or convictions about power in shaping this choice. Within the framework of an explorative qualitative study, we engaged in in-depth interviews with 12 young environmentally concerned citizens. On this basis, five main findings are elaborated. Firstly, powerlessness is shown to be a crucial experience, whatever the respondents’ engagement. Secondly, ‘strategy scepticism’ seems to be a more important obstacle for engagement than ‘climate scepticism’. Thirdly, many respondents express significant resistance towards being ‘conditioned’ by awareness-raising campaigns. Fourthly, a ‘gap’ is observed between respondents’ analysis and their strategy proposals. Finally, we underscore another important gap between concrete and abstract levels in respondents’ discourses. All these findings disclose paradoxical aspects of the role of power in shaping the concerned citizens’ engaged choices. 相似文献

We propose an operationalization of the rural and urban analogy introduced in Becher and Trowler (2001). According to them, a specialism is rural if it is organized into many, smaller topics of research, with higher author mobility among them, lower rate of collaboration and productivity, lower competition for resources and citation recognitions compared to an urban specialism. It is assumed that most humanities specialisms are rural while science specialisms are in general urban: we set to test this hypothesis empirically. We first propose an operationalization of the theory in most of its quantifiable aspects. We then consider specialisms from history, literature, computer science, biology, astronomy. Our results show that specialisms in the humanities present a sensibly lower citation and textual connectivity, in agreement with their organization into more, smaller topics per specialism, as suggested by the analogy. We argue that the intellectual organization of rural specialisms might indeed be qualitative different from urban ones, discouraging the straightforward application of citation-based indicators commonly applied to urban specialisms without a dedicated re-design in acknowledgement of these differences. 相似文献

Over the past decades, science funding shows a shift from recurrent block funding towards project funding mechanisms. However, our knowledge of how project funding arrangements influence the organizational and epistemic properties of research is limited. To study this relation, a bridge between science policy studies and science studies is necessary. Recent studies have analyzed the relation between the affordances and constraints of project grants and the epistemic properties of research. However, the potentially very different affordances and constraints of funding arrangements such as awards, prizes and fellowships, have not yet been taken into account. Drawing on eight case studies of funding arrangements in high performing Dutch research groups, this study compares the institutional affordances and constraints of prizes with those of project grants and their effects on organizational and epistemic properties of research. We argue that the prize case studies diverge from project-funded research in three ways: 1) a more flexible use, and adaptation of use, of funds during the research process compared to project grants; 2) investments in the larger organization which have effects beyond the research project itself; and 3), closely related, greater deviation from epistemic and organizational standards. The increasing dominance of project funding arrangements in Western science systems is therefore argued to be problematic in light of epistemic and organizational innovation. Funding arrangements that offer funding without scholars having to submit a project-proposal remain crucial to support researchers and research groups to deviate from epistemic and organizational standards. 相似文献

Four experiments examined the utility of real-time text in supporting deaf students' learning from lectures in postsecondary (Experiments 1 and 2) and secondary classrooms (Experiments 3 and 4). Experiment 1 compared the effects on learning of sign language interpreting, real-time text (C-Print), and both. Real-time text alone led to significantly higher performance by deaf students than the other two conditions, but performance by deaf students in all conditions was significantly below that of hearing peers who saw lectures without any support services. Experiment 2 compared interpreting and two forms of real-time text, C-Print and Communication Access Real-Time Translation, at immediate testing and after a 1-week delay (with study notes). No significant differences among support services were obtained at either testing. Experiment 3 also failed to reveal significant effects at immediate or delayed testing in a comparison of real-time text, direct (signed) instruction, and both. Experiment 4 found no significant differences between interpreting and interpreting plus real-time text on the learning of either new words or the content of television programs. Alternative accounts of the observed pattern of results are considered, but it is concluded that neither sign language interpreting nor real-time text have any inherent, generalized advantage over the other in supporting deaf students in secondary or postsecondary settings. Providing deaf students with both services simultaneously does not appear to provide any generalized benefit, at least for the kinds of materials utilized here. 相似文献

Teachers’ beliefs are crucial to the success of inclusion programmes and reform efforts for children with special educational needs (SEN). Based on this evidence, one hundred and thirty‐nine primary pre‐service teachers from one training institution in the Netherlands completed an adapted version of a measure of beliefs towards inclusive education. In contrast to previous studies on pre‐service teachers, results of this study showed participants held neutral or negative beliefs towards this matter. In addition, limited time for pupils received the highest rating as a barrier to inclusion, whereas direct teaching experience was the most preferred method of inclusion. The implications of this study for practice and indications for future research are discussed. 相似文献

The aim of this study was to assess the effect of manipulating stroke rate on the distribution of mechanical power in rowing. Two causes of inefficient mechanical energy expenditure were identified in rowing. The ratio between power not lost at the blades and generated mechanical power (P(rower)) and the ratio between power not lost to velocity fluctuations and P(rower) were used to quantify efficiency (e(propelling) and e(velocity) respectively). Subsequently, the fraction of P(rower) that contributes to the average velocity (chi(boat)) was calculated (e(net)). For nine participants, stroke rate was manipulated between 20 and 36 strokes per minute to examine the effect on the power flow. The data were analysed using a repeated-measures analysis of variance. Results indicated that at higher stroke rates, P(rower), chi(boat), e(propelling), and e(net) increase, whereas e(velocity) decreases (P < 0.0001). The decrease in e(velocity) can be explained by a larger impulse exchange between rower and boat. The increase in e(propelling) can be explained because the work at the blades decreases, which in turn can be explained by a change in blade kinematics. The increase in e(net) results because the increase in e(propelling) is higher than the decrease in e(velocity). Our results show that the power equation is an adequate conceptual model with which to analyse rowing performance. 相似文献

This paper examines how network relations between firms influence firm survival by explicitly addressing the moderating role of changing technological regimes. Using longitudinal data on 1385 developers and 190 publishers of video games in the global video game industry between 1972 and 2007, the analyses show that the effect of network ties between developers and publishers on the survival probability of developers is moderated by the level of technological turbulence in the industry. The results show that the effect of network partner failure on firm survival is dependent on the strength of ties. The failure of strongly tied network partners harms developers in stable periods and benefits them in turbulent eras, while no such relation is found for weakly tied network partners. Network partner diversity positively affects firm performance in epochs of technological turbulence, while the effect plays no significant role for firm survival in stable settings. The results indicate that the relation between interfirm network relations and firm survival are moderated by sequences of technological renewal in the video game industry which causes the industry to go through an evolution that deviates from the typical S-shaped trajectory found in industries that are characterized by strong path-dependent processes. 相似文献

Rowers need to combine high sprint and endurance capacities. Muscle morphology largely explains muscle power generating capacity, however, little is known on how muscle morphology relates to rowing performance measures. The aim was to determine how muscle morphology of the vastus lateralis relates to rowing ergometer performance, sprint and endurance capacity of Olympic rowers. Eighteen rowers (12♂, 6♀, who competed at 2016 Olympics) performed an incremental rowing test to obtain maximal oxygen consumption, reflecting endurance capacity. Sprint capacity was assessed by Wingate cycling peak power. M. vastus lateralis morphology (volume, physiological cross-sectional area, fascicle length and pennation angle) was derived from 3-dimensional ultrasound imaging. Thirteen rowers (7♂, 6♀) completed a 2000-m rowing ergometer time trial. Muscle volume largely explained variance in 2000-m rowing performance (R2 = 0.85), maximal oxygen consumption (R2 = 0.65), and Wingate peak power (R2 = 0.82). When normalized for differences in body size, maximal oxygen consumption and Wingate peak power were negatively related in males (r = ?0.94). Fascicle length, not physiological cross-sectional area, attributed to normalized peak power. In conclusion, vastus lateralis volume largely explains variance in rowing ergometer performance, sprint and endurance capacity. For a high normalized sprint capacity, athletes may benefit from long fascicles rather than a large physiological cross-sectional area. 相似文献

As the number of globally mobile students has expanded, governments are assumed to be consistently and intentionally competing for talent, in what has been called a “great brain race”. While the notion of competition has become dominant, there is little evidence on long-term policy dynamics in this field, not only across jurisdictions but also over time. We seek to address this gap in this paper through a longitudinal analysis of the politics and public policies impacting international students in four major recruiting countries—Australia, Canada, England and the USA. Through this comparative analysis of the period 2000 to 2016, we demonstrate that international student numbers across the jurisdictions have grown steadily but that this appears to be decoupled from political and policy changes. We also discuss how “internationalization” initiatives provide an insufficient policy umbrella for policy action on the recruitment and retention of international students. Public policy impacting international students spans multiple government agencies or ministries, encompassing different policy fields. This requires greater policy coordination, which remains elusive for the most part. 相似文献
