Librarians offer a unique perspective on e-books: on one hand they collect these resources and train users as part of their jobs, while on the other hand, they may be users of e-books themselves. With recent increases in research expectations for Canadian academic librarians, this study aimed to discover: when librarians do research, do they use e-books and how often are they using them? This study examines the results of a survey of 392 academic librarians from across Canada. The survey generated data on librarians' use of, and attitudes towards, e-books. While a number of studies examine the use and opinions of e-books among other user groups, this study examines how librarians search for or use e-books differently than other user groups. Results will help librarians to improve their liaison work and make more informed collection development decisions at their own institutions. 相似文献

In 1994, the New South Wales Board of Studies, Australia, introduced three high level Distinction Courses for gifted and talented students: comparative literature, cosmology, and philosophy. All are offered by distance education but the cosmology course employs an interactive design model and an extensive communication system that differentiates it from the other two. This article explains the model and the way it is used in practice to organize, sequence and deliver the course. Discussion addresses ways in which the model might be used to design a wider range of courses for gifted and talented students. 相似文献

Currently, all elite high jumpers use the Fosbury Flop technique with a curved approach. This suggests that the curved approach presents some clear advantage, although there is no general agreement upon the mechanism or the mechanics. This study aimed to determine the characteristics of the approach curve and to investigate how it contributes to the generation of somersault rotation. A simple theoretical model was used to demonstrate that a tightening approach curve would change the inward lean towards the centre of the curve into outwards lean. Three-dimensional video analysis was used to record the performances of two elite male high jumpers in competition. It was found that in each case the radius of the approach curve and the inward lean angle both decreased towards the end of the approach. The amount of outward lean angular velocity generated was shown to be a major proportion of the required somersault angular velocity for a jump. It was concluded that the main advantage of a curved approach was that it resulted in the generation of somersault velocity providing the curve tightened towards the end of the approach. 相似文献

Extending an important rhetorical tradition of investigating women's positioning/positionalities in the national imaginary, in society, and in the law, this essay examines how non-US citizen women and their experiences are deployed toward objectives of the US state. Specifically, I analyze the rhetorical significance of two precedent-setting gender-based asylum cases, those of Fauziya Kassindja and Rody Alvarado, to understand the different ways non-US women are positioned by the state. These cases reveal that women claimants, depending on the nuances of their claims, are incorporated into the state as “good” women, pushed to the margins because their rhetoric is “threatening,” or appropriated by the state because their “otherness” provides an image that the United States can deploy in demonstrating itself as the “good” state that protects and supports women. 相似文献

This paper presents comparative questionnaire data from three different samples of Australian high school students in an attempt to see if anything has changed in relation to how they perceive the science they experience in the compulsory years of secondary school (grades 7–10). Questionnaire data were obtained from 1,585 high school students in 2011 and 2,016 students in 2005 and findings are compared with those reported in a national report (Goodrum et al. 2001). Results show significant increases in the frequency with which students report that their science teacher takes notice of their ideas and in the use of computers and the Internet. There have also been changes regarding the rapid provision of feedback, the use of understandable language by teachers and the contextualisation of the new work in terms of work already covered. Little appears to have changed, however, in relation to the teacher-directed pedagogies employed to teach science where there appears to be a higher incidence of copying notes and fewer opportunities for students to investigate topics in which they are interested. The findings suggest that while there have been some positive changes, there are still many students who indicate that the science they experience in secondary school is irrelevant to their everyday life and to their future. It seems that the curiosity and wonder one would hope is associated with studying science is missing for a large proportion of students. It is clear that further actions need to be undertaken to transform this continuing situation. 相似文献

In the mid-1990s, US immigration courts were introduced to a group of Iranian women who claimed that they feared persecution because of their “pro-Western and feminist” political opinions and because of the way they performed gender on their bodies. The claims were, in total, unsuccessful bids to asylum. Analyzing these cases set against the geopolitical background of US–Iranian history and contemporary relations, I argue that their denials illustrate three important dynamics. First, building on rhetorical theorizing of voice and body, this essay demonstrates the uneasy reception in US law and politics of willful noncitizen women of color with explicit political voices and bodies, and second, the consequential racialization of these subjects as willful, unorderable migrant subjects too akin in their sovereignty to their state of birth. Third, this analysis adds to the field's attentiveness to geopolitics by consequently demonstrating US necropolitical desires toward Iran in the state's engagement with these cases. I argue that for the United States to recognize these claimants as having political voices contrary to their state would be to recognize the presence and legitimacy of that state—a sovereign that challenges US power and modernity on the global stage. 相似文献
