Physiological correlates of performance in international-standard squash players
Tactical, technical and fitness factors are important for success in elite squash. While tactical and endurance fitness aspects have been explored, altered demands that have resulted from rule changes and absence of specific tests of high-intensity exercise capabilities have prevented identification of elements of fitness that correlate with performance in elite-standard players. Accordingly, the purpose of this study was to investigate relationships between test scores and player rank in such players. With institutional ethics approval, 31 players from the England Squash performance programme participated (11 women and 20 men, mean±SD body mass 62.4±5.5 kg and 73.1±7.5 kg respectively). After habituation, participants completed countermovement and drop-jump tests, squash-specific tests of change-of-direction speed and multiple-sprint ability and the multistage fitness test in one test session. Short recoveries were allowed between tests. World rank at the time of testing was obtained from the Professional Squash Association website. In men, change-of-direction speed (??=?0.59, p?=?0.02, n?=?14) multiple-sprint ability (??=?0.78, p<0.01, n?=?13) and fastest sprint from the multiple-sprint test (??=?0.86, p<0.01, n?=?13) correlated with world rank. In women, only fastest repetition from the multiple-sprint test correlated with world rank (??=?0.65, p?=?0.04, n?=?10). Measures of high-intensity exercise capability correlated with world rank in elite-standard men and women players. Endurance capability did not relate to rank in either the men or women. The results suggest that high-intensity, variable-direction exercise capabilities are important for success in elite squash
Two Tales of Entrepreneurship: Barbados, Jamaica, and the 1973 Oil Price Shock
From 1961 to 2011, Barbados’s GDP per capita grew roughly two times faster than Jamaica’s.
As a result, the income gap between Barbados and Jamaica is now more than three times larger than at the time of independence. Qualitative historical analysis, exploiting the interplay between public policy and entrepreneurship before and after the 1973 oil price shock, demonstrates that pro-entrepreneurial policies in Barbados versus anti-business policies in Jamaica explain in part the economic divergence of these two islands
Cooling SABER with a miniature pulse tube refrigerator
Utah State University/Space Dynamics Laboratory (USU/SDL), teaming with NASA Langley Research Center, is currently building the Sounding of the Atmosphere using Broadband Emission Radiometry(SABER) instrument. Stringent mass and power constraints, together with a greater than two year mission life, led to the selection of a TRW miniature pulse tube refrigerator to cool SABER\u27s infrared detectors to the required temperature of 75 K.
This paper provides an overview of the SABER thermal management plan and the challenges encountered in matching the refrigerator characteristics with instrument performance requirements under the broadly variant space environments expected for this mission. Innovative technologies were developed to keep heat loads within the limited cooling capacity of the miniature refrigerator, as well as mechanically isolating but thermally connecting the refrigerator cold block to the focal plane assembly (FPA). A passive radiator will maintain the SABER telescope at an average temperature of 230 K while a separate radiator will reject heat from the refrigerator and electronics at approximately 260 K.
Significant breadboard tests of various components of the SABER instrument have taken place and the details of one of these will be discussed. The test included attaching a miniature mechanical refrigerator, borrowed from the Air Force, to the SABER FPA. This opportunity gave the SABER team a significant head start in learning about integrating and testing issues related with the TRW miniature pulse tube refrigerator.
SABER is scheduled to be launched in January 2000 as the primary instrument of NASA\u27s TIMED (Thermosphere-lonosphere-Mesosphere Energetics and Dynamics) spacecraft. The TIMED program is being managed by the Applied Physics Laboratory at Johns Hopkins University
Facilitation Differentially Affects Competitive Responses of Aspen and Subalpine Fir Through Stages of Stand Development
Spatial interactions between trees influence forest community succession. The objective of this study was to investigate how shifts in forest composition and proximity between tree species affect stand development over time in mixed forest systems. At six locations across the Fishlake National Forest, Utah, USA, in stands where facilitation has been documented previously, tree-ring samples were collected from aspen and subalpine fir trees. Basal area increment was calculated to characterize the effects of the proximity of overstory trees on multidecadal growth responses of aspen and subalpine fir in aspen-dominant and mixed aspen–conifer stands. Subalpine fir seedlings were established next to aspen (within 10 cm) when aspen was between 15 and 120 years old with a mean age of 60 years. Aspen and subalpine fir growth rates were reduced with increasing conifer abundance. Aspen trees growing next to a proximate subalpine fir tree had slower growth rates over time than aspen trees growing independently. Growth rates of subalpine fir in aspen-dominated stands were similar when growing independently or near aspen trees. However, subalpine fir in conifer-dominated stands maintained higher growth rates when growing next to an aspen tree than when growing independently. The data suggest that as stand competition increases with conifer abundance, the proximity of overstory trees increases competitive exclusion of aspen while having a beneficial growth effect on subalpine fir. These results underscore the importance of maintaining natural fire regimes in forest systems that keep competitive interactions in balance
Motor control in musculsoskeletal physiotherapy: a concept analysis
Background research and clinical practice however the meaning of the term is unclear. A review of the literature revealed variation in the use of the concept of motor control within and between the specialties of the physiotherapy profession. In addition, the literature identi interchangeably with terms such as neuromotor control and neuromuscular control. The ambiguity of the term may cause miscommunication and misunderstanding in physiotherapy education, research and clinical practice.: The term motor control is used commonly in physiotherapyfied that motor control is used Purpose (MSK) physiotherapy practice.: To clarify the concept of motor control and its use in musculoskeletal Methods investigate the socially constructed concept of motor control. Literature between 2009 to 2014 was selected from CINAHL, AMED and Medline databases to provide contemporary, peer reviewed and relevant data on the concept. Two hundred and ten abstracts were reviewed from which 50 studies were included in the analysis due to their relevance to physiotherapy practice. An inductive process of analysis was used to collect the attributes, antecedents, consequences and related terms of the concept of motor control.: The evolutionary method of concept analysis was used to Results the literature that included musculoskeletal, neurological and paediatric physiotherapy specialty areas. The highest number of research articles that used motor control was within the musculoskeletal literature (n The term motor control was used interchangeably with neuromuscular control, neuromotor control and core stability.

Defining Success in Perioperative Care Pathways for Hip Fracture Patients
PURPOSE: Hip fracture is an increasingly common cause of morbidity and mortality in the aging U.S. population. Multiple studies have shown that patients who undergo surgical repair within 48 hours of the initial injury have better outcomes. The use of a perioperative care pathway (PCP) for hip fracture patients combines prompt surgical repair with dedicated medical services tailored to patients’ specific comorbidities.
METHODS: Our level 1 trauma center implemented a PCP in October 2015, requiring only anesthesia (not hospital medicine) clearance prior to surgery. We identified all hip fracture patients who presented to our level 1 hospital for one year prior to, and one year following, implementation of the pathway. We then performed a comprehensive clinical chart review to collect demographic data, past medical history, and perioperative factors. We performed statistical analyses to evaluate whether using the pathway improved patient outcomes.
RESULTS: Preliminary analyses were performed on a series of patients pre- (n=96) and post-pathway (n=100). We summarized patient characteristics and reported these according to participation in the pathway. Distributions were evaluated for normality and to evaluate for outliers. Proportions were reported for categorical variables and assessed for differences using the chi-square test, and continuous data were summarized by means and standard deviations and assessed for differences using the t-test. We found that patients in the pathway worked with physical therapy (PT) an average of 16.8 hours earlier (p=0.013).
CONCLUSION: The use of PCPs represents an emerging approach to hip fracture management, but a widely generalizable PCP has yet to be definitively described. Our patients’ decrease in time to PT may be attributable to better postoperative optimization by hospitalist medicine. We anticipate that multivariate analyses will reveal additional gains. Ultimately, our experience may yield implications for the safe, cost- and time-effective surgical care of hip fracture patients nationally
