Scientists are users of science journals in two senses—to enter their own work and to learn of others—but are rarely the direct purchaser of them. The health of research is inextricably bound up with the learned journal. Muck is contributed by scientists to their journals in invisible ways, such as refereeing and editing. The creation of an archive of information is the primary service the journal supplies. Libraries pay for its entry into the system; research organizations and university faculties must recognize that this cost has to be met. The views expressed here are those of a publisher as well as of a user. 相似文献

A great challenge in education research involves the difficulty of differentiating between studies that apply commonly understood
theoretical perspectives and recognizing studies that merely rename old theoretical frameworks. This conflict between intellectual
innovation and intellectual retrofitting emerges as central to Basu, Calabrese-Barton, Clairmont, and Lock’s exploration of
the relationship between critical agency and student identity development in science.

The game of hurling is ranked as one of the fastest and most skilful field games in the world. It is played by a stick, hurley, made of ash wood and a ball, sliotar, made of a cork core or similar viscoelastic materials. Better standardisation of the game equipment requires analysing impacts to quantify precisely the effect of variations in equipment design on the resultant impact force at low and high striking speeds. Therefore, the purpose of the present study was to use a high-speed camera to (1) characterise the impact dynamics in term of impact force magnitude and duration, and (2) investigate whether a relationship exists between the game equipment and the magnitude of the impact force. An air cannon unit (ACU) test rig was set up to cause the sliotar to strike the hurley at predetermined speeds. A high-speed camera operating at 12,500 frames per second (fps) was used to capture 32 experimental impacts covering a range of sliotar and hurley brands, impact locations and impact speeds. The factor ??sliotar brand?? was identified as the most significant factor for the impact force among other main factors and two-factor interactions at a constant speed and it had a significant effect with up to 27?% difference between sliotar brands. It was demonstrated that, at higher impact speeds, the force?Cdeformation curves of the sliotar brands varied significantly, even though similar force?Cdeformation curves have been reported at quasi-static compression and similar COR values at low impact speeds using the standard free-drop test. This is the first known study to characterise the unique, highly non-linear and anisotropic sliotar?Churley impact using high-speed camera technology. It highlights the need for a tighter standard for sliotar materials and manufacturing to increase uniformity between different brands and strongly suggests that the standard free-drop test is not sufficient to characterise and compare game equipment. 相似文献

In this paper, we employ Critical Race Theory theoretically and methodologically to examine the racialized experiences of students of color in higher education and student affairs (HESA) graduate preparation programs. We employ counter-storytelling as a method for constructing narratives that disrupt the master narrative found within HESA graduate preparation programs, which often boast an espoused commitment to diversity and social justice. Based on a study of 29 graduate students of color in 21 master’s programs across the United States, the counter-stories reflect the endemic nature of racism in graduate education including the classroom, academic program, and campus. Students expressed experiences of tokenization, disappointment, feelings of frustration, anger, and racial battle fatigue. Implications for improving racial climates in graduate education are also shared. 相似文献

ABSTRACT This paper describes a small scale research project to pilot the loan of portable computers to students and staff for use on or off‐campus. The purpose of the research is to identify organisational procedures and associated problems, find out how these portable computers are used, and whether or not they are an effective and efficient use of resources. Take‐up of the scheme in its first phase indicates popularity with students and positive outcomes. Very high use was recorded and many students report that use in their own time and in the atmosphere of their own surroundings encourages greater self‐confidence in information technology. They also consider that access to the portables has proved significant, with the quality of their work enriched. Such experiences raise important questions about the organisation of computing facilities and focus issues beyond the viability and economics of portable computer loan schemes. Within the outcomes of the project, there should be useful data pointing to the need to develop imaginative policies and funding models whereby each student can own or have ready access to their own personal computer. An important outcome of this could be the increased use of information technology by initial teacher education students, resulting in a corresponding increase in the transference of confidence, and use of information technology by children and other teachers in school. 相似文献

To optimize students’ learning outcomes, educators are increasingly expected to use instructional practices shown to be effective by credible research. To help make this possible, organizations and scholars are producing resources that summarize research related to various instructional practices. However, as the collection of resources grows in size and complexity, it can be difficult and frustrating for practitioners to locate and utilize this information. In this article, we describe the 6S Pyramid (DiCenso, Bayley, & Haynes, 2009), a framework for efficiently and accurately prioritizing different types of research evidence. We also identify and briefly summarize Internet resources corresponding with each level of the Pyramid that can be used to identify research‐based practices for students with learning disabilities. To illustrate how the 6S Pyramid can be used in school and classroom settings, we begin and end the article with vignettes featuring a pair of co‐teachers seeking to improve instruction for their students who struggle with reading. 相似文献

Bryan R. Warnick 《Educational theory》2016,66(5):581-598
In this essay Bryan Warnick examines two recent analyses of the practice of paying students for grades, with a focus on educational justice. Philosopher Derrick Darby argues against cash‐for‐grades programs on the grounds that such programs leave educational inequality intact. Warnick contends that Darby's arguments are incomplete. Increasing levels of educational “adequacy” is morally desirable, Warnick argues, even if inequality remains unchanged. There is also an obligation to engage in “localized practice reforms” that benefit small groups of disadvantaged students, even if such reforms do not change the structural problems that lead to inequality. At the same time, engaging in a close analysis of “cash” as an incentive does reveal specific reasons why the inequality that persists under cash‐for‐grades might be particularly troublesome. In contrast to Darby, Alexander Sidorkin argues that paying students for learning is not only allowed, but ethically obligatory. Schooling, for Sidorkin, is a form of labor and labor demands fair compensation. Warnick challenges the idea that schooling is a form of exploited labor by looking across a range of issues, including the nonpecuniary benefits of schooling. At the same time, it seems that schooling could become a form of exploited labor, given current trends. Overall, the justice of cash incentive programs remains an open question. The essay concludes with a discussion about how we can move forward with a philosophical analysis of cash‐for‐grades programs. 相似文献

Ensuring quick and consistent access to large collections of unstructured documents is one of the biggest challenges facing knowledge-intensive organizations. Designing specific vocabularies to index and retrieve documents is often deemed too expensive, full-text search being preferred despite its known limitations. However, the process of creating controlled vocabularies can be partly automated thanks to natural language processing and machine learning techniques. With a case study from the biopharmaceutical industry, we demonstrate how small organizations can use an automated workflow in order to create a controlled vocabulary to index unstructured documents in a semantically meaningful way. 相似文献
