Differences between the sexes in the three-dimensional angular rotations of the lumbo-pelvic-hip complex during treadmill running

The aims of this experiment were to determine whether there are differences between the sexes in the three-dimensional angular rotations of the lumbo-pelvic-hip complex during running and, if such differences exist, to establish whether factors other than sex can explain the observed differences. A cohort of 44 non-injured runners (22 males, 22 females) who usually ran more than 20 km per week were voluntarily recruited. All trials were conducted on a treadmill at a running speed of 4.0 m x s(-1). Reflective markers were placed over specific anatomical landmarks of the thoraco-lumbar spine, pelvis and femur. Data were captured using a VICON motion analysis system. Females tended to display a greater peak-to-peak oscillation for most of the angular rotations. An offset was the main difference between the male and female group mean waveforms for pelvis anterior-posterior tilt. Forward stepwise regression analysis revealed that sex was the most common variable related to the amplitudes of the angular rotations. Given these results, sport scientists conducting future biomechanical studies using angular data to test hypotheses are advised to be extremely cautious about averaging across male and female participants.     

Work/training programs for international health science librarians in American medical school libraries

World understanding is more than a desirable goal today: it may be crucial to our survival. Many universities realize this and have in the past decade spent a great deal of time and money to ensure a steady flow of faculty and students between the U.S. and other countries. Librarians with faculty or academic status may benefit from promoting such relationships themselves. Job exchanges and training programs offer librarians in the United States the opportunity to become acquainted with their counterparts in other countries. Such programs enable librarians of various countries to become aware of one another's special needs and common problems, and allow them to share ideas and expertise. This paper presents an overview of international training programs for foreign librarians in the United States, focusing on programs for health sciences librarians in United States medical school libraries. Information is given on the availability and types of institutionally sponsored programs, as well as on MLA's Cunningham Fellowship Program. Some of the difficulties and the benefits of such programs are discussed.     

Access management: the overlooked but critical enabler

• Access management (AM) is a critical, but often overlooked, enabler for publishers looking to expand the appeal of their online resources.
• This article examines why publishers underinvest in AM, and provides practical examples of how this impacts productivity and growth across the organization.
• Three AM trends that offer new growth opportunities are also explored: (i) enabling a wider range of customer types and business models, (ii) supporting a more diverse range of access scenarios, and (iii) facilitating greater personalization through identity management.
• Publishers need to review their AM strategy in light of these opportunities. In particular, publishers that currently support AM in‐house should outsource to specialist vendors if they are not fully committed to investing the expertise and time needed to support this increasing sophistication.

     

Evolution of the Transfer Code of Practice

The Transfer Code of Practice was launched in 2008 as a set of best‐practice guidelines to be followed when a journal changes publisher, with the aim of ensuring uninterrupted access to content for subscribers. The Code has now been updated to reflect the continued evolution of the academic publishing process driven by new technologies, policies, and publishing practices.     

Knowledge of bout duration influences pacing strategies during small-sided games

This investigation examines pacing during intermittent team sports. Sixteen junior Rugby League players participated in eight different small-sided offside touch games. All games were 24 min, but bout durations differed in continuous (1 × 24 min) or repeated (2 × 12, 3 × 8, 4 × 6, 6 × 4, 8 × 3, 12 × 2 or 24 × 1 min) formats. Repeat bouts were interspersed by 2 min of passive rest, and participants were informed of the bout duration immediately prior to the game. Heart rates, ratings of perceived exertion and data gathered from global positioning system devices were used to investigate the pacing strategies employed within each game. No significant (P > 0.05) between-game differences were observed in total distance; however, during the 1-min bouts, high-speed movement was significantly (P < 0.05) increased, during the first and second quarters of the 24 × 1-min game compared to all other formats (effect size range: 0.75 ± 0.61–1.38 ± 0.47). Furthermore, the rate of decline in high-speed movement over-time was greatest during the 24 × 1-min game with large differences observed between the first and third quarters (effect size: 0.90 ± 0.58). Greater moderate-speed (effect size range: 0.62 ± 0.63–1.56 ± 0.40) and less low-speed (effect size range: 0.69 ± 0.62–1.54 ± 0.40) distances were also observed during the 1-min bouts, yet heart rates were higher during the continuous 1 × 24-min game. Pacing strategies during intermittent activities are influenced by the number and duration of exercise bouts. Practitioners should consider within-game bout durations when prescribing game-based activities to improve aerobic capacity.     

Between education and psychology: school staff perspectives

When discussing contributions from psychology in/to educational practices like school-based mental health promotion, it is peculiar that psychologists (of an educational or clinical kind) or education-oriented sociologists, both not often based in schools or classrooms, dominate the topic. It has been acknowledged that school staff have been over looked and underutilised in contributing to the discussion, particularly as this pertains to sharing perspectives on how they experience their role in relationship to education policy and practice. The study presented here looked to address this situation by seeking the perspectives of school staff on a range of concerns situated at the nexus between education and psychology. Contrary to the type of displaced assessment intimated above, this group of school staff generally accepts they perform a crucial task in supporting students, their main concern being to incisively question how they might negotiate existing role-related pressures to better current school-based practice.
