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

AbstractThe 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

ABSTRACTIn 1974, the Brazilian sports official João Havelange was elected FIFA’s president in a two-round election, defeating the incumbent Stanley Rous. The upset, often attributed to a successful alliance with Asia, the Middle East and Africa, what at the time was referred to as the Third World – surprised observers everywhere. Here, the election can be analysed as a historically relevant event of social significance. It can be thought of as a political window by means of which the international dynamic of a specific moment in the Cold War can be perceived, especially the limitations and potentialities of the agency available to periphery countries at that time. In this article, I intend to discuss the narratives that forged the history of FIFA, which take this political ‘event’ as a key in the institution’s own historical transformation. The sources analysed will be mainly FIFA official histories, such as the FIFA News, FIFA historical books and movies about the history of FIFA. 相似文献

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

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.

Many studies have concentrated on investigating educational expenditure and pupil–teacher ratio to see how these two factors can influence the quality of education. This study chooses to examine these two educational factors from a different perspective. If educational expenditure and pupil–teacher ratio really have a significant impact on the quality of education as many studies have claimed, it is important to step back and understand why some regions choose to have high/low educational expenditure and high/low pupil–teacher ratios. This study found that culture has an important impact on these two educational factors. Hofstede's cultural dimensions, namely Power Distance and Individualism, were applied and results showed that these two cultural dimensions, when applied to 43 regions around the world, demonstrated a significant impact on educational expenditure and pupil–teacher ratio. 相似文献
