Recruitment into the scientific community is one oft-stated goal of science education--in the post-Sputnik United States, for example--but this obscures the fact that science textbooks are often read by people who will never be scientists. It cannot be presupposed that science textbooks for younger audiences, students in primary and secondary schools, function in this way. For this reason, precollegiate-level science textbooks are sometimes discussed as a subset of literature popularizing science. The high school science classroom and the textbook are forums for exposing the public to science. The role of governments and educational institutions in regulating the consumption of these texts not only determines which books are used; it influences how they are written, read, and deemed authoritative. Therefore such science textbooks should not be seen as (at best) the disjunction of texts-for-training and books-for-popularization. A changing sense of what "textbooks" are compels a different understanding of their use in the history of science.  相似文献

People from Generation Y, given their number and stage in the family life-cycle, represent a key emerging audience for major sports. The study focussed on the effect of friends and half time enhancements on likely attendance at matches. The sport domain was the Australian Football League (AFL), the elite Australian rules football competition. The enhancements being tested were half-time entertainments based on performers from well-known television talent shows, Australian Idol and It Takes Two. Scenarios with and without interactive participation, based on short messaging service (SMS) messages, were tested. The study used a general population sample of 909 Generation Y people in a traditional AFL market and one where AFL is not the major winter competition. Previous attendance and sport orientation were the major influences on attendance at major sports, including the AFL. Friends influenced likely attendance at a game, but no effects were found for half-time entertainments. People who attended matches with friends typically had social activities before and after the game. This suggested that one promotional strategy to expand existing markets was to find and engage the social networks of existing fans, making sport attendance a broader part of an overall social event.  相似文献

The demand for greater public accountability is changing the nature of ex ante peer review at public science agencies worldwide. Based on a four year research project, this essay examines these changes through an analysis of the process of grant proposal review at two US public science agencies, the National Institutes of Health (NIH) and the National Science Foundation (NSF). Weaving historical and conceptual narratives with analytical accounts, we describe the ways in which these two agencies struggle with the question of incorporating considerations of societal impact into the process of peer review. We use this comparative analysis to draw two main conclusions. First, evaluation of broader societal impacts is not different in kind from evaluation of intellectual merit. Second, the scientific community may actually bolster its autonomy by taking a broader range of considerations into its peer review processes.  相似文献

We present a new method for analyzing a student's learning over time for a specific skill: analysis of the graph of the student's moment-by-moment learning over time. Moment-by-moment learning is calculated using a data-mined model that assesses the probability that a student learned a skill or concept at a specific time during learning (Baker, Goldstein, & Heffernan, 2010 Baker, R. S. J. d., Goldstein, A. B. and Heffernan, N. T. 2010. “Detecting the moment of learning”. In Proceedings of the 10th Annual Conference on Intelligent Tutoring Systems 2534. In V. Aleven, J. Kay, & J. Mostow (Eds.),pp.Heidelberg, Germany: Springer.[Crossref] [Google Scholar], 2011). Two coders labeled data from students who used an intelligent tutoring system for college genetics. They coded in terms of 7 forms that the moment-by-moment learning curve can take. These labels are correlated to test data on the robustness of students’ learning. We find that different visual forms are correlated with very different learning outcomes. This work suggests that analysis of moment-by-moment learning curves may be able to shed light on the implications of students’ different patterns of learning over time.  相似文献

This essay explores the relations between T. S. Eliot's concept of tradition and the ‘modern materialism’ of Walter Benjamin, Jacques Lacan and Louis Althusser, and considers the implications of this resonance for both Eliot's critical legacy and the Marxist tradition. Initially surveying the critical controversy surrounding the canonical figure of Eliot and recent attempts to reconcile his avant-garde poetics with his reactionary social thought, the essay traces the roots of Eliot's tradition in a Nietzschean critique of historicism and its development into a theory of culture. Eliot's persistent drive towards impersonality echoes (and problematises) the efforts of Benjamin, Lacan and Althusser to construct a model of the social process that incorporates the unconscious. Rather than ultimately determining a set of political positions, the ‘missed encounter’ between Eliot's tradition and ‘modern materialism’ draws to light the Hegelian historicisms that haunt materialist theories of culture.  相似文献

ABSTRACT

The effectiveness of 8-week force-velocity optimised training was assessed in highly trained professional rugby league athletes. Players (age 24 ± 3 years; body mass 94.9 ± 21.6 kg; height 181.3 ± 6.0 cm) were strength-matched and assigned to a force-velocity optimised group (OP; n = 15) or a general strength-power group (GP; n = 14). Tests included 10-m, 20-m sprints, 3 repetition-maximum squat and squat jumps over five load conditions to ascertain vertical force-velocity relationship. ANCOVA revealed there was a group effect for force-velocity deficit (P < 0.001), with the OP two-fold greater than the GP group (OP pre: 51.13 ± 31.42%, post: 62.26 ± 31.45%, GP pre: 33.00 ± 19.60%, post: 31.14 ± 31.45%, P < 0.001). There were further group effects for 3RM squat (OP pre: 151.17 ± 22.95 kg, post: 162.17 ± 24.16 kg, GP pre: 156.43 ± 25.07 kg, post: 163.39 ± 25.39 kg, P < 0.001), peak power (OP pre: 3195 ± 949 W, post: 3552 ± 1033 W, GP pre: 3468 ± 911 W, post: 3591 ± 936 W, P < 0.001), and SJ (OP pre: 39.79 ± 7.80 cm, post: 42.69 ± 7.83 cm, GP pre: 40.44 ± 6.23 cm, post: 41.14 ± 5.66 cm, P < 0.001). Prescribing F-V deficit training is superior for improving physical performance within highly trained RL players.  相似文献

In this article, I do two things. First, I describe and evaluate progress that has been made to date on implementing five recommendations made by the author to the leadership of Elliot Lake Public Library in 2014, intended to assist in disaster recovery efforts following the destruction of the library in an anthropogenic disaster in 2012. Second, I provide three revised recommendations, this time intended to assist library leadership address some continuing challenges that are preventing the complete recovery of the library, and ultimately, negatively impacting the effectiveness of the library within the community.  相似文献

This study examined factors that might affect researchers' willingness to collaborate with a specific researcher and the priorities given to those factors. In addition, it investigated how researchers determined the ownership of collaborative project data and how they determined the order of authorship on collaborative publications in condensed matter physics. In general, researchers rated their intrinsic motivations the highest, such as the quality of ideas a potential collaborator might have and their satisfaction with a past collaboration, followed by their extrinsic motivations, such as the complementary knowledge, skills, or resources the collaborator could provide. In addition, researchers who had a greater number of collaborative projects and researchers who had served as a project PI or co-PI valued the deep-level, personality-related characteristics of a collaborator higher than did those who had not. Younger researchers were more risk averse and more concerned with a collaborator's reputation and the possible cost of a collaboration decision. Additionally, younger researchers indicated more often than older researchers that they did not know whether their project teams followed any rules or norms or engaged in negotiation to determine the order of authorship on collaborative publications.  相似文献
