An examination of the internal consistency and structure of the Statistical Anxiety Rating Scale (STARS).

The purpose of the current study was to examine the internal consistency and structure of the English version of the Statistical Anxiety Rating Scale (STARS). Participants were 202 (79% females) psychology undergraduates was recruited from James Cook University's Singapore (71%) and Australia (29%) campuses. Acceptable internal consistency reliabilities, ranging from .81 to .94, were found in this sample. Approximate fit indices suggest that a correlated six first-order factor model best describes the data in contrast to theoretical considerations suggesting that a six factor model with two correlated superordinate factors (i.e., statistics anxiety and attitudes toward statistics) best describes the data. Researchers are recommended to use part one of the STARS to assess statistics anxiety and part two to assess attitudes toward statistics.

Transferring an Analytical Technique from Ecology to the Sport Sciences.

BACKGROUND: Learning transfer is defined as an individual's capability to apply prior learnt perceptual, motor, or conceptual skills to a novel task or performance environment. In the sport sciences, learning transfers have been investigated from an athlete-specific perspective. However, sport scientists should also consider the benefits of cross-disciplinary learning to aid critical thinking and metacognitive skill gained through the interaction with similar quantitative scientific disciplines. OBJECTIVE: Using team sports performance analysis as an example, this study aimed to demonstrate the utility of a common analytical technique in ecology in the sports sciences, namely, nonmetric multidimensional scaling. METHODS: To achieve this aim, three novel research examples using this technique are presented, each of which enables the analysis and visualization of athlete (organism), team (aggregation of organisms), and competition (ecosystem) behaviors. RESULTS: The first example reveals the technical behaviors of Australian Football League Brownlow medalists from the 2001 to 2016 seasons. The second example delineates dissimilarity in higher and lower ranked National Rugby League teams within the 2016 season. Lastly, the third example shows the evolution of game play in the basketball tournaments between the 2004 and 2016 Olympic Games. CONCLUSIONS: In addition to the novel findings of each example, the collective results demonstrate that, by embracing cross-disciplinary learning and drawing upon an analytical technique common to ecology, novel solutions to pertinent research questions within sports performance analysis could be addressed in a practically meaningful way. Cross-disciplinary learning may subsequently assist sport scientists in the analysis and visualization of multivariate datasets.

Effect of portable non-invasive ventilation & environmental conditions on everyday activities.

The current study examined the effect of non-invasive ventilation (NIV) within environments of differing temperature and humidity on several physiological and perceptual responses while performing six activities of daily living (i.e. putting on shirt/shoes/trousers, vacuuming, hanging towels, and walking on a treadmill). Sixteen healthy participants completed the activities of varying difficulty within four experimental conditions: with and without NIV; and in temperate (22°C, 40% relative humidity) and hot-humid environments (32°C, 70% relative humidity). Comparisons of physiological responses between conditions were examined via repeated measures ANOVAs. Overall, NIV resulted in similar physiological and perceptual responses within all environmental conditions for healthy participants. Further, NIV use increased heart rate during the most strenuous task (29.5±12.7 vs. 22.8±12.0bpm, p=0.008) indicating NIV use may stress cardiovascular functioning during moderate-high intensity activities. Tropical conditions did not alter physiological or perceptual responses during everyday tasks with NIV use by healthy adults. Future investigations examining the independent and combined impacts of task intensity, extreme environments and NIV use will clarify the benefits of NIV for healthy and clinical populations.

Health advice obtained by tourists travelling to Magnetic Island: a risk area for 'Irukandji' jellyfish in North Queensland, Australia.

BACKGROUND: Little is known about the travel health advice obtained by tourists travelling to Magnetic Island, which is a known risk area for the potentially fatal 'Irukandji' jellyfish on the Great Barrier Reef coast of north Queensland, Australia. METHODS: Structured interviews were conducted with 208 ferry passengers (93% response) travelling between Townsville (Latitude 19 degrees S) and Magnetic Island. RESULTS: Less than half of the international tourists (21, 46%) had obtained travel health advice before coming to north Queensland, although they were significantly more likely to have done so than domestic tourists (p<0.001). Travel health advice obtained by international tourists was sourced mainly from their general practitioner (8, 50%) or from a guidebook (6, 38%). Eighty-eight percent of north Queensland residents, 70% of domestic tourists, and 34% of international tourists knew what an Irukandji jellyfish was (p<0.001), although this was not associated with having obtained travel health advice. For those passengers returning from the Island, 8 (44%) domestic tourists and 4 (35%) international tourists recalled seeing some information on the Island that improved their knowledge about Irukandji jellyfish. Most of the international tourists travelled to north Queensland by bus (30, 65%), while most domestic tourists arrived by private car (12, 40%) or plane (10, 33%). CONCLUSIONS: Only a small proportion of international tourists knew about Irukandji jellyfish and most tourists had not received travel health advice. The majority of tourists had not received further information about Irukandji jellyfish risk whilst on the island. All travellers to popular north Queensland tourist areas need travel health advice, which includes advice on avoiding contact with Irukandji and Chironex box jellyfish. Health promotion campaigns directed at providing this advice need to be aware that most tourists to north Queensland arrive by bus or car and the only 'shared' vehicle, at least to Magnetic Island, is the passenger ferry.

Reported knowledge, perceptions, and behavior of tourists and North Queensland residents at risk of contact with jellyfish that cause the "Irukandji syndrome".

OBJECTIVE: To determine the knowledge, beliefs, and behavior of local residents and visitors to North Queensland who may be at risk of contact with "Irukandji" jellyfish. METHODS: Structured interviews were conducted with 208 ferry passengers (92.9% response) traveling between Magnetic Island and Townsville (19 degrees S). RESULTS: A total of 88.1% of the locals, 69.8% of the domestic tourists, and 34% of the international tourists knew what an Irukandji was (P < .001). Half of the international tourists, 20% of the domestic tourists, and 3.9% of the locals with this knowledge incorrectly assumed it was safe to swim inside stinger-resistant enclosures or were unsure (P < .001). Visitors to Magnetic Island who had swum or intended to swim in the sea (47%) knew less about Irukandji than other visitors (P = .05). Only 42.3% of the respondents realized that Irukandji posed a risk to swimmers on the outer reefs, and only 33.1% knew that Irukandji were also found outside North Queensland. CONCLUSIONS: International tourists had little knowledge about Irukandji. Thus, accurate educational messages may need to be targeted at this group. Offshore water sport and reef tour operators should be encouraged to provide clients with protective clothing to minimize the risk of stings. A coordinated educational response across northern Australia may be necessary to inform the public about both the box jellyfish (Chironex fleckeri) and Irukandji.
