Open access megajournals: The publisher perspective (Part 1: Motivations)

This paper is the first of two Learned Publishing articles in which we report the results of a series of interviews with senior publishers and editors exploring open access megajournals (OAMJs). Megajournals (of which PLoS One is the best known example) represent a relatively new approach to scholarly communication and can be characterized as large, broad‐scope, open access journals that take an innovative approach to peer review, basing acceptance decisions solely on the technical or scientific soundness of the article. This model is often said to support the broader goals of the open science movement. Based on in‐depth interviews with 31 publishers and editors representing 16 different organizations (10 of which publish a megajournal), this paper reports how the term ‘megajournal’ is understood and publishers’ rationale and motivations for launching (or not launching) an OAMJ. We find that while there is general agreement on the common characteristics of megajournals, there is not yet a consensus on their relative importance. We also find seven motivating factors that were said to drive the launch of an OAMJ and link each of these factors to potential societal and business benefits. These results suggest that the often polarized debate surrounding OAMJs is a consequence of the extent to which observers perceive publishers to be motivated by these societal or business benefits.     

Active recovery of the finger flexors enhances intermittent handgrip performance in rock climbers

This study aimed to (1) evaluate the effect of hand shaking during recovery phases of intermittent testing on the time–force characteristics of performance and muscle oxygenation, and (2) assess inter-individual variability in the time to achieve the target force during intermittent testing in rock climbers. Twenty-two participants undertook three finger flexor endurance tests at 60% of their maximal voluntary contraction until failure. Performances of a sustained contraction and two intermittent contractions, each with different recovery strategies, were analysed by time–force parameters and near-infrared spectroscopy. Recovery with shaking of the forearm beside the body led to a significantly greater intermittent test time (↑ 22%, P?P?P?相似文献   

Evaluating the Effectiveness of Physlet-Based Materials in Supporting Conceptual Learning About Electricity

To provide a good understanding of many abstract concepts in the field of electricity above that of their students is often a major challenge for secondary school teachers. Many educational researchers promote conceptual learning as a teaching approach that can help teachers to achieve this goal. In this paper, we present Physlet-based materials for supporting conceptual learning about electricity. To conduct research into the effectiveness of these materials, we designed two different physics courses: one group of students, the experimental group, was taught using Physlet-based materials and the second group of students, the control group, was taught using expository instruction without using Physlets. After completion of the teaching, we assessed students’ thinking skills and analysed the materials with an independent t test, multiple regression analyses and one-way analysis of covariance. The test scores were significantly higher in the experimental group than in the control group (p < 0.05). The results of this study confirmed the effectiveness of conceptual learning about electricity with the help of Physlet-based materials.     

Toward a constructivist perspective: The impact of a mathematics teacher inservice program on students

A constructivist-oriented inservice program provided teachers of mathematics (K-12) with intensive two-week summer institutes and weekly classroom follow-up. Pre- and post-program data on student outcomes indicate that, along with transformations in the nature and quality of mathematics activity in the classroom, students' beliefs about learning mathematics changed and elementary students' attitudes toward mathematics improved. Although the instruction they now received focused more on conceptual understanding and less on computational skill, students' scores on standardized tests assessing routine knowledge were maintained.An earlier version of this paper appeared in R. Underhill (ed.),Proceedings of the Thirteenth Annual Meeting of the North American Chapter of the International Group for the Psychology of Mathematics Education 1, 43–49, Backsburg, VI.     

Using stroke removal to investigate Chinese character identification during reading: evidence from eye movements

We explored the effect of stroke removal from Chinese characters on eye movements during reading to examine the role of stroke encoding in character identification. Experimental sentences were comprised of characters with different proportions of strokes removed (15, 30, and 50%), and different types of strokes removed (beginning, ending, and strokes that ensured the configuration of the character was retained). Reading times, number of fixations and regression measures all showed that Chinese characters with 15% of strokes removed were as easy to read as Chinese characters without any strokes removed. However, when 30%, or more of a character’s strokes were removed, reading characters with their configuration retained was easiest, characters with ending strokes removed were more difficult, whilst characters with beginning strokes removed were most difficult to read. The results strongly suggest that not all strokes within a character have equal status during character identification, and a flexible stroke encoding system must underlie successful character identification during Chinese reading.

Higher education in East Asia and Singapore: rise of the Confucian Model

The paper reviews Asia–Pacific higher education and university research, focusing principally on the “Confucian” education nations Japan, Korea, China, Hong Kong China, Taiwan, Singapore and Vietnam. Except for Vietnam, these systems exhibit a special developmental dynamism—still playing out everywhere except Japan—and have created a distinctive model of higher education more effective in some respects than systems in North America, the English-speaking world and Europe where the modern university was incubated. The Confucian Model rests on four interdependent elements: (1) strong nation-state shaping of structures, funding and priorities; (2) a tendency to universal tertiary participation, partly financed by growing levels of household funding of tuition, sustained by a private duty, grounded in Confucian values, to invest in education; (3) “one chance” national examinations that mediate social competition and university hierarchy and focus family commitments to education; (4) accelerated public investment in research and “world-class’ universities. The Model has downsides for social equity in participation, and in the potential for state interference in executive autonomy and academic creativity. But together with economic growth amid low tax regimes, the Confucian Model enables these systems to move forward rapidly and simultaneously in relation to each and all of mass tertiary participation, university quality, and research quantity and quality.     

全球化背景下高等教育公私属性的思考

用萨缪尔森的产品概念来界定高等教育产品的公私属性,并以此来分析高等教育的全球性、浮现的世界市场和全球公共产品,那么以是否国有来界定高等教育产品的属性就行不通了.若从社会特性来区分产品的公私属性,那么全球的高等教育产品只能分为非排他性和非竞争性两类.由于公共产品往往在市场上生产不足,所以,充分认识高等教育私有产品在世界市场上的内在属性有现实意义.     

The Effects of Late Arts Education on Adults with Early Visual Disabilities

In this study, non-participant observations of visually disabled adult students in extra mural arts education are analysed through Walter Doyle’s theory of ambiguity and risk in classroom tasks. This study finds these students attempted to avoid activity, or re-negotiate lecturers’ expectations, when their performance became especially threatening to their self-esteem. Additionally, it was found that lecturers were often reluctant to push their students as soon as they realised this risk to them. These results appear to show a phenomenon similar to learned helplessness.
