Tweeting biomedicine: an analysis of tweets and citations in the biomedical literature

Data collected by social media platforms have recently been introduced as a new source for indicators to help measure the impact of scholarly research in ways that are complementary to traditional citation-based indicators. Data generated from social media activities related to scholarly content can be used to reflect broad types of impact. This paper aims to provide systematic evidence regarding how often Twitter is used to diffuse journal articles in the biomedical and life sciences. The analysis is based on a set of 1.4 million documents covered by both PubMed and Web of Science (WoS) and published between 2010 and 2012. The number of tweets containing links to these documents was analyzed to evaluate the degree to which certain journals, disciplines, and specialties were represented on Twitter. It is shown that, with less than 10% of PubMed articles mentioned on Twitter, its uptake is low in general. The relationship between tweets and WoS citations was examined for each document at the level of journals and specialties. The results show that tweeting behavior varies between journals and specialties and correlations between tweets and citations are low, implying that impact metrics based on tweets are different from those based on citations. A framework utilizing the coverage of articles and the correlation between Twitter mentions and citations is proposed to facilitate the evaluation of novel social-media based metrics and to shed light on the question in how far the number of tweets is a valid metric to measure research impact.Comment: 22 pages, 4 figures, 5 table

Contribution of Trunk Rotation and Abdominal Muscles to Sprint Kayak Performance.

Over the past two decades the importance of trunk contribution to sporting performance has been highlighted through the expanse of literature concerning core stability and strength. However, the role of trunk motion and the abdominal muscles are yet to be established during sprint kayak performance. The purpose of this study was to determine the associations among trunk rotation, kayak velocity, and abdominal muscle activity during on-water sprint kayaking. Eight international paddlers completed five 150 m sprint trials. During each trial peak muscle activation (peak root-mean-squared electromyogram) of the latissimus dorsi, rectus abdominus, external obliques and rectus femoris for ipsilateral (stroke side) and contralateral (opposite side) were recorded as the paddler passed through a 5-m calibrated volume, in conjunction with upper and lower trunk rotation and kayak velocity. Results indicated a significant strong negative relationship between lower trunk rotation and peak velocity (r = -0.684, p < 0.05). Furthermore, a significant strong positive relationship (p < 0.05) with mean velocity was identified for the contralateral rectus abdominus and multiple significant associations between the rectus femoris, rectus abdominus and external obliques during the paddle stroke. Findings indicate that limiting the rotation of the lower trunk will increase both the peak and the mean velocity, with the rectus abdominus, external oblique and rectus femoris combining to assist in this process. Training should therefore focus on developing the strength of these muscle groups to enhance performance. [Abstract copyright: Copyright: © Academy of Physical Education in Katowice.

Do mountain tourists demand ecotourism? Examining moderating influences in an Alpine tourism context

Ecotourists appreciate nature and are willing to learn about nature and ecology. Therefore ecotourism is often seen as a product package that supports sustainable tourism development. This study contributes to existing research in the field of ecotourism as it investigates how travel motives and environmental concern of mountain tourists influences their actual demand for ecotourism. A survey of mountain tourists in the Austrian Alps was conducted and reveals a positive relationship between environmental concern and ecotourism demand. The study measured travel motives, which are compatible and incompatible with ecotourism and showed how these motives influence actual demand of ecotourism. Furthermore it is postulated that education, income and the intention to revisit the destination moderate the relationship between environmental concern, mountain tourists’ motives and the tourists’ demand for ecotourism. For destination marketing it can be stated that higher educated mountain tourists with a high disposable income are a vital market segment, which should be targeted for ecotourism in the mountains. Research recommendations are highlighted and focus on loyal visitors, as it remains unclear whether loyalty with an ecotourism destination strengthens the demand for ecotourism

QUANTIFYING THE GRADIENTS EXPOSED TO A PROFESSIONAL GOLFER DURING A ROUND OF GOLF

Research has suggested that that when performing a tee shot a gradient slope of 4.4% (2.25°) and above it is noticeable to the golfer and may cause an adjustment to their normal stance (Linde, 2005). To quantify what gradients were exposed to a golfer during a round of golf an inclinometer was utilised to measure the gradient of shots in open play from around 16 golf courses across the UK. Twenty two right handed male professional golfers were recruited and the inclinometer was placed between the inside of the feet and the ball. The results showed that over 50% of shots where performed on an incline greater than 2.25° mainly ranging from 0 to (+/-) 10°. These results suggest that future research is required to investigate the effects of gradient on the mechanics of the golf swing

Empirical insights into innovation practices as crises response of ski destinations after the first lockdown of the COVID-19 pandemic

The tourism industry is very vulnerable and is strongly affected by the pandemic. Thus, it requires innovative solutions to cope with and recover from the crisis. The study aims at gaining empirical insights into innovation behavior as means to crisis response of ski destinations. For this purpose, we conducted 20 semi-structured interviews with key stakeholders of ski destinations during the re-start of tourism after the first lockdown in Austria. We further explore how ski destinations develop and implement various types of innovations as a response to the COVID-19 pandemic and reveal that the COVID-19 crisis improves coopetition among stakeholders. The research suggests that the COVID-19 crisis has reinforced innovation activities and the interviews demonstrate that the role of DMOs has become even more important for destination recovery

THE EFFECTS OF COMPRESSION SHORTS ON MUSCLE OSCILLATION AND LONG JUMP PERFROMANCE

Compression garments were used to explore their effect on athletic performance and muscle oscillation during a 3-step long jump task. The study consisted of a 3 dimensional kinematic analysis (Vicon Motus 9.2) with force data collected by a Kistler force platform. Ten male subjects performed 6 jumps under 2 conditions, bare leg (control condition) and with the compression shorts. Two-tailed paired samples T-test were conducted to discover significant changes in the measures of Muscle Oscillation (MO), Peak Vertical Ground Reaction Force (PVGRF), Peak Horizontal Ground Reaction Force (PHGRF) and Jump Length. The findings of the study suggest that long jump performance can be increased (.18m) while wearing compression shorts, although the legs ability to disperse force may be reduced by the garment
