Demystifying the publication process – a structured writing program to facilitate dissemination of teaching and learning scholarship     

Debbi Weaver  Diane Robbie  Alex Radloff 《International Journal for Academic Development》2013,18(3):212-225

This paper reports on a writing program to support academic staff to publish in peer-refereed journals. Nine participants completed a 12-week program, which involved regular meetings, set writing tasks, and peer feedback on drafts. A pre- and post-survey and follow-up interviews were used to gather feedback. Participants especially valued the discipline of weekly sessions and peer feedback. They reported increased skills and confidence in their writing, greater knowledge of the publication process, and intention to continue writing. Although five papers were published, a 12-month follow-up revealed that original writing intentions were not sustained. Thus, while a structured writing program can be effective, the pressures academic staff experience trying to meet conflicting requirements of teaching, administration, and research, must also be addressed.  相似文献

Association between knee-to-hip flexion ratio during single-leg vertical landings,and strength and range of motion in professional soccer players

Abstract

The aim of this study was to test the correlation between knee-to-hip flexion ratio during a single leg landing task and hip and knee strength, and ankle range of motion. Twenty-four male participants from a professional soccer team performed a continuous single leg jump-landing test during 10s, while lower limb kinematics data were collected using a motion analysis system. After biomechanical testing, maximal isometric hip (abduction, extension, external rotation), knee extension and flexion strength were measured. Maximum ankle dorsiflexion range of motion was assessed statically using the weight bearing lunge test. Pearson correlation coefficients were calculated to determine the associations between the predictor variables (knee and hip strength, and ankle ROM) and the main outcome measure (knee-to-hip flexion ratio). Correlation between knee-to-hip flexion ratio and hip abductors strength was significant (r = ?0.47; p = 0.019). No other significant correlations were observed among the variables (p > 0.05). These results demonstrated that a lower hip abductors strength in male soccer players was correlated with a high knee-to-hip flexion ratio during landing from a single leg jump, potentially increasing knee overload by decreasing energy absorption at the hip. The results provide a novel proposal for the functioning of hip muscles to control knee overload.  相似文献   

The kinematic differences between accurate and inaccurate squash forehand drives for athletes of different skill levels

ABSTRACT

To maintain the accuracy of squash shots under varying conditions, such as the oncoming ball’s velocity and trajectory, players must adjust their technique. Although differences in technique between skilled and less-skilled players have been studied, it is not yet understood how players vary their technique in a functional manner to maintain accuracy under varying conditions. This study compared 3-dimensional joint and racket kinematics and their variability between accurate and inaccurate squash forehand drives of 9 highly skilled and 9 less-skilled male athletes. During inaccurate shots, less-skilled players hit the ball with a more open racket, demonstrating a difference in this task-relevant parameter. No joint kinematic differences were found for accuracy for either group. Coordinated joint rotations at the elbow and wrist both displayed a “zeroing-in” effect, whereby movement variability was reduced from the initiation of propulsive joint rotation to a higher consistency at ball-impact; potentially highlighting the “functionality” of the variability prior to the impact that enabled consistent task-relevant parameters (racket orientation and velocity) under varying conditions. Further, highly skilled players demonstrated greater consistency of task-relevant parameters at impact than less-skilled players. These findings highlight the superior ability of highly skilled players to adjust their technique to achieve consistent task-relevant parameters and a successful shot.  相似文献

Weeding with Wisdom: Tuning Deselection of Print Monographs in Book-Reliant Disciplines     

Alex D. McAllister  Allan Scherlen 《资料收集管理》2017,42(2):76-91

As university libraries transition to digital collections and new services, their book deselection projects often lead to the adoption of cross-discipline quantitative weeding criteria (such as age and low circulation) in the interest of speed and presumed fairness. Cross-discipline quantitative rubrics, however, can have unintended negative consequences when applied to disciplines such as history and literature that rely on older books with low circulation statistics. The authors argue for a discipline-differentiated approach to weeding academic library collections that can employ quantitative criteria for disciplines, such as in the sciences, that are more reliant on current materials and qualitative criteria for disciplines, such as in the humanities, whose scholars benefit from ready access to older and low-use books.  相似文献   

Closing the PDF gap: ReadCube’s experiments in reader‐focused design          下载免费PDF全文

Alex Hodgson  Lucas Schlager 《Learned Publishing》2017,30(1):65-69

Key points

• Twenty years ago, a fraction of articles were paired with supplements; now, one in five research stories go beyond PDF.
• Why has the evolution of research content's delivery vehicles lagged behind the evolution of the research story?
• Hyperlinked in‐line references are the most used feature of the Enhanced PDF – exposing faster, easier ways to follow the path of research.
• Discovery need not start and end with the search engine – it can start within the PDF itself.
• Discovery is not a solitary process; therefore, content platforms must support collaboration to drive readership.

Journey around Leadership     

Amanda Sinclair 《Discourse: Studies in the Cultural Politics of Education》2004,25(1):7-19

Ideas about leadership in education, as in other areas of professional practice, increasingly borrow from management and business thinking. In this article I provide a commentary and critique of contemporary leadership in the form of a narrative of my own experience as an educator in a business school. My experience as a woman teacher of largely male, adult management students has underscored my learning about and critique of leadership theory and my own aspirations as teacher and leader. Personal experience is interwoven with theoretical commentary to highlight the limitations of leadership discourses—too often disembodied, de‐gendered and de‐sexualized. By inserting my responses and feelings I also seek to subvert, or at least to add some different dimensions to, intellectualized and inert critiques of leadership. Learning about leadership, including engagement, reaction and contestation, is not just a cerebral undertaking, but emotion laden and thoroughly embodied. I sought to reflect these qualities in this article.  相似文献
