TL;DR: The most common known genetic cause of intellectual disability is Down syndrome (DS) as discussed by the authors, which affects ∼1 per 650-1000 live births and is the most common cause of disability.
Abstract: Background: Down syndrome (DS) affects ∼1 per 650-1000 live births and is the most common known genetic cause of intellectual disability. A highly significant change in the survival of people with DS has occurred during the last two generations, with life expectancy estimates increasing from 12 to nearly 60 years of age. Subjects and Methods: Detailed information on 1332 people in Western Australia with DS was abstracted from a specialist statewide database for the period 1953-2000 and electronically linked with three other state or national health and mortality data sources and the state Birth Defects Registry. Results: Over the last 25 years the percentage of women over 35 years giving birth increased from 4.8 to 18.6%, accompanied by an increase in the overall prevalence of DS from 1.1 to 2.9 per 1000 births. Four life stages of DS were identified: prenatal, childhood and early adulthood, adulthood, and senescence. Although pneumonia, or other types of respiratory infections, was the most common cause of death across the entire lifespan, ranging from 23% of deaths in adulthood to 40% in senescence, each life stage exhibited a particular profile of comorbidities. Congenital heart defects were common causes in childhood (13%) and adulthood (23%), whereas in senescence coronary artery disease (10%) and cardiac, renal, and respiratory failure (9%) were leading causes of mortality. Conclusions: A major re-appraisal in attitudes towards DS is required to ensure that the medical and social needs of people with the disorder are adequately met across their entire lifespan. In particular, specific recognition of the comorbidities that can arise at different ages is needed, accompanied by the provision of appropriate levels of care and management.

TL;DR: This paper considers game design for successful exergames and draws on established principles from sports science for the prescription of exercise programs to identify success factors to guide designers of exergaming systems.
Abstract: Exergaming is the use of video games in an exercise activity. In this paper we consider game design for successful exergames. To do this, we review the history of exergaming and the current state of research in this field. We find that there exists some research aimed at evaluating the physical and health characteristics of exergames, but research on how to design exercise games is still in the early stages. From an analysis of this information, and drawing on established principles from sports science for the prescription of exercise programs, we then attempt to identify success factors to guide designers of exergaming systems.

TL;DR: This unusual pattern of hydraulic regulation, referred to here as isohydrodynamic, is explained by a hydromechanical stomatal control model where plant hydraulic conductance is dependent on transpiration rate.
Abstract: Isohydric and anisohydric regulations of plant water status have been observed over several decades of field, glasshouse and laboratory studies, yet the functional significance and mechanism of both remain obscure. We studied the seasonal trends in plant water status and hydraulic properties in a natural stand of Eucalyptus gomphocephala through cycles of varying environmental moisture (rainfall, groundwater depth, evaporative demand) in order to test for isohydry and to provide physiological information for the mechanistic interpretation of seasonal trends in plant water status. Over a 16 month period of monitoring, spanning two summers, midday leaf water potential (Ψleaf) correlated with predawn Ψleaf, which was correlated with water table depth below ground level, which in turn was correlated with total monthly rainfall. Eucalyptus gomphocephala was therefore not seasonally isohydric. Despite strong stomatal down-regulation of transpiration rate in response to increasing evaporative demand, this was insufficient to prevent midday Ψleaf from falling to levels below −2 MPa in the driest month, well into the region likely to induce xylem air embolisms, based on xylem vulnerability curves obtained in the study. However, even though midday Ψleaf varied by over 1.2 MPa across seasons, the hydrodynamic (transpiration-induced) water potential gradient from roots to shoots (ΔΨplant), measured as the difference between predawn and midday Ψleaf, was relatively constant across seasons, averaging 0.67 MPa. This unusual pattern of hydraulic regulation, referred to here as isohydrodynamic, is explained by a hydromechanical stomatal control model where plant hydraulic conductance is dependent on transpiration rate.

TL;DR: In this paper, the authors argue that design-based research is feasible for doctoral students, and that candidates should be encouraged to engage in it more specifically, they describe the components of a dissertation proposal or prospectus that utilizes designbased research methods in the context of educational technology research.
Abstract: At first glance, design-based research may appear to be such a long-term and intensive approach to educational inquiry that doctoral students, most of whom expect to complete their PhD degree in 4-5 years, should not attempt to adopt this approach for their doctoral dissertations In this paper, we argue that design-based research is feasible for doctoral students, and that candidates should be encouraged to engage in it More specifically, we describe the components of a dissertation proposal or prospectus that utilizes design-based research methods in the context of educational technology research

TL;DR: In this paper, the authors argue that owner aspirations are integral to whether or not SMEs strategically plan, and that strategic planning may therefore have little value to owner-operators driven by such motivators.
Abstract: Considerable evidence shows that strategic planning leads to increased firm performance. Yet, the majority of SMEs do not plan and the reasons why are not well understood. This article questions the common approach to understanding this problem based on identifying business barriers to planning. For the majority of SME owneroperators, business performance often ranks far behind intangible goals such as autonomy, personal satisfaction and lifestyle. Strategic planning may therefore have little value to owner-operators driven by such motivators. This article presents an alternative perspective to the issue by arguing that owner aspirations are integral to whether or not SMEs strategically plan.

TL;DR: In this paper, the authors examine and analyse where and how information and communication technologies (ICT) are integrated in Singapore schools to engage students in higher-order thinking activities, taking the activity system as a unit of analysis.
Abstract: This paper examines and analyses where and how information and communication technologies (ICT) are integrated in Singapore schools to engage students in higher-order thinking activities. Taking the activity system as a unit of analysis, the study documents the actual processes and sociocultural elements that engage students in higher-order thinking. By employing methods such as observations, focus group discussions with students, and face-to-face interviews with teachers, ICT-coordinators and principals, an account of how the activity systems within and between classrooms, and the schools are generated. Based on the analysis of the data from 10 schools, issues in the learning environment are discussed: Necessary (classroom management and orienting activities) and sufficient conditions (scaffolding activities and supporting school policies) for effective ICT integration in the classroom. The account also highlights the constraints of time and lack of knowledge and experience in the contexts that the teachers are working under, and how these constraints are addressed by supporting school policies in the larger sociocultural setting of the school. This account provides a sample of pedagogical and sociocultural issues that are discussed over the course and at the end of the project. Like a good guidebook, the study sensitizes the audience to what is likely to happen given a particular objective, constraint, or design.

TL;DR: Evaluating the reliability of comparable TTE and TT treadmill running tests of high and moderately high exercise intensity in endurance-trained male distance runners found log-log modeling using the TTE test results reliably predicted actual TT performance.
Abstract: Both time-to-exhaustion (TTE) and time-trial (TT) exercise tests are commonly used to assess exercise performance, but no study has directly examined the reliability of comparable tests in the same subjects.
Purpose: To evaluate the reliability of comparable TTE and TT treadmill running tests of high and moderately high exercise intensity in endurance-trained male distance runners, and to validate Hinckson and Hopkins TT prediction methods using log-log modeling from TTE results.
Methods: After familiarization tests, eight endurance-trained male distance runners performed, in a randomized, counterbalanced order, eight trials consisting of two 5-km TT and two 1500-m TT, and four TTE tests run at a speed equivalent to the average speed attained during both the 5-km and 1500-m TT distances.
Results: Typical error of the estimate (TEE) expressed as a coefficient of variation for the 5-km TT, 5-km TTE, 1500-m TT, and 1500-m TTE were 2.0, 15.1, 3.3, and 13.2%, respectively. The standard error of the estimate for predicted TT running speed using log-log modeling from TTE results was 0.67%, and the predicted versus criterion reliability of this method revealed TEE values of 1.6% and 2.5% for the prediction of 5-km and 1500-m TT, respectively.
Conclusion: The variability of 5-km and 1500-m TT tests was significantly less than for similar TTE treadmill protocols. Despite the greater variability of the TTE tests, log-log modeling using the TTE test results reliably predicted actual TT performance.
TL;DR: In this paper, the extent to which the environmental disclosures in annual reports of companies listed on the Kuala Lumpur Stock Exchange are associated with corporate characteristics was examined, and the findings suggested that environmental disclosure is negatively associated with company financial performance.
Abstract: Purpose – The purpose of this paper is to examine the extent to which the environmental disclosures in annual reports of companies listed on the Kuala Lumpur Stock Exchange are associated with corporate characteristics.Design/methodology/approach – A rating system for environmental disclosures was developed, based on a review of previous studies, embracing industry membership, financial performance, share price fluctuations, political cost proxies, dependence on debt and the capital market.Findings – The findings suggested that environmental disclosure is negatively associated with company financial performance. A significant inverse relationship between disclosure score and return on assets is apparent, suggesting that environmental disclosure in Malaysia has different priorities from disclosures elsewhere.Originality/value – This study is the first of its kind to be conducted in Malaysia, and its empirical findings complement the expectations of prior studies.
TL;DR: This study reviews the six 2D barcodes evaluated using eight criteria for standardization potential and uses an additional metric - a first-read rate - to quantitatively verify earlier results and better gauge reading reliability.
Abstract: In a previous study, we evaluated six 2D barcodes using eight criteria for standardization potential: omnidirectional symbol reading, support for low-resolution cameras, reading robustness under different lighting conditions, barcode reading distance, error correction capability, security, support for multiple character sets, and data capacity. We also considered the fidelity of the camera phone's captured image as a metric for gauging reading reliability. Here, we review the six 2D barcodes and then use an additional metric - a first-read rate - to quantitatively verify our earlier results and better gauge reading reliability.
TL;DR: It is concluded that the presence of marine-derived wrack plays a major role in subsidising production of macroinvertebrates on beaches of south-western Australia and suggests that marine subsidies can play a role in supporting terrestrial production, even in oligotrophic marine environments.
Abstract: Beach-cast wrack is a prominent feature of beaches of south-western Australia. We examined the fauna of these beaches to explore the generalisation [Polis, G.A., Hurd, S.D., 1995. Extraordinarily high spider densities on islands: flow of energy from the marine to terrestrial food webs and the absence of predation. Ecology 92, 4382–4386] that beach-cast wrack from highly productive marine ecosystems subsidises low productivity of terrestrial ecosystems, to establish whether this generalisation is relevant to oligotrophic marine systems. We sampled three beaches with high and three beaches with low volumes of beach-cast wrack to determine if: (1) the presence of wrack influences the abundance of macroinvertebrates; (2) wrack acts as a food source for beach macroinvertebrates; and (3) the influence of wrack varies between zones above the high water mark. We measured wrack volume and composition, sediment characteristics, the abundance of different epibenthic and infaunal macroinvertebrates taxa, and δ 13 C and δ 15 N of macrophytes and macroinvertebrates. The mean volume of wrack on high-wrack beaches was 0.27–1.07 m 3 wrack m −2 compared to 0.00–0.09 m 3 wrack m −2 on low-wrack beaches. There were no significant differences in sediment grain size, moisture content or loss on ignition between the two types of beaches or zones. Epibenthic fauna and infauna were consistently abundant on high-wrack beaches (20–291 and 0.5–3.5 individuals 0.64 m −2 , respectively), but either absent or extremely rare in low-wrack beaches (0–3 and 0–0.1 individuals 0.64 m −2 , respectively). Within high-wrack beaches, there were no significant differences in the abundance of epifauna or infauna among beaches or between zones. The δ 13 C values of macroinvertebrates at all sites were most similar to red and brown algae, with the exception of beetles from two beaches, which were closest to seagrasses. Mixing model (Isosource) results for mesograzing amphipods and dipteran flies suggested carbon was assimilated mostly from the seagrass Posidonia spp., the dune grass Spinifex longifolia and red algae for amphipods and from brown algae, red algae and dune vegetation for dipteran flies. We conclude that the presence of marine-derived wrack plays a major role in subsidising production of macroinvertebrates on beaches of south-western Australia. We suggest that marine subsidies can play a role in supporting terrestrial production, even in oligotrophic marine environments.
TL;DR: In this paper, the authors investigated age and gender differences in initial motivations for starting a business and found that self-employment is a reactive rather than proactive decision for both older women and men; however, women were less in...
Abstract: Purpose – This paper aims to investigate age and gender differences in initial motivations for starting a business. What is not known, however, is whether the initial motivations for starting the business are different for older people and whether any gender differences exist. Historically, women were “pushed” rather than “pulled” into business ownership, but more recent studies have indicated that, overall, many women now actively choose self‐employment. However, age may be a new barrier for women and men.Design/methodology/approach – The study combined a self‐administered questionnaire which was used to collect data relating to general information about the respondent and their business, in addition to their start‐up motivations. In total 270 questionnaires were returned. About 15 in‐depth interviews were also conducted to verify the empirical findings.Findings – The results showed that self‐employment is a reactive rather than proactive decision for both older women and men; however, women were less in...
TL;DR: A review of the concept of whiteness and how the power and privilege of white privilege is reproduced within societies such as Australia and South Africa is presented in this paper, where the authors highlight and establish dialogue about how research on whiteness may contribute to decolonisation and work towards social justice.
Abstract: This article is a review of the concept of whiteness and how the power and privilege of whiteness is reproduced within societies such as Australia and South Africa. As well as providing a broad overview of whiteness, our aim is to highlight and establish dialogue about how research on whiteness may contribute to decolonisation and work towards social justice. The review begins by outlining the meanings and complexity of whiteness. having established some parameters for understanding whiteness the second part of the article focuses on how whiteness produces itself. Three different, but related, practices or mechanisms through which whiteness is reproduced have been identified in the literature. These have been labelled: knowledge and history construction; national identity and belonging; and anti-racism practice. In conclusion, we briefly discuss how we are investigating whiteness further in relation to pedagogy and applied research. While this article is not aimed at providing a complete review of whiteness, it does provide a background against which we can start thinking differently about racism, race relations, and anti-racism. These different ways of thinking include interrogating power and privilege in the analysis of racism, which in turn may lead to more effective and critical action addressing racism.
TL;DR: It is proposed that physical verisimilitude to real situations is of less importance in learning than “cognitive realism,” provided by immersing students in engaging and complex tasks.
Abstract: THE DEVELOPMENT of immersive learning technologies in the form of virtual reality and advanced computer applications has meant that realistic creations of simulated environments are now possible. Such simulations have been used to great effect in training in the military, air force, and in medical training. But how realistic do problems need to be in education for effective learning to occur? Some authors and researchers argue that problems should be real, or that simulations should have ultrarealistic physical similarity to an actual context. This paper proposes that physical verisimilitude to real situations is of less importance in learning than “cognitive realism,” provided by immersing students in engaging and complex tasks. The paper presents a description of the theory and research that provide the foundations for this approach. Examples of courses employing cognitive, rather than physical, realism are presented together with the views of teachers, authors and instructional designers. Finally, the implications of this approach are discussed.
TL;DR: Compared the power output values obtained from 4 different methods were compared to examine the relationships between these values and to understand the characteristics of each method and consider how power output should be measured during the hang power clean and the weighted jump squat.
Abstract: Measurement of power output during resistance training is becoming ubiquitous in strength and conditioning programs, but there is great variation in the methods used. The main purposes of this study were to compare the power output values obtained from 4 different methods and to examine the relationships between these values. Male semiprofessional Australian rules football players (n = 30) performed hang power clean and weighted jump squat while ground reaction force (GRF)-time data and barbell displacement-time data were sampled simultaneously using a force platform and a linear position transducer attached to the barbell. Peak and mean power applied to the barbell was obtained from barbell displacement-time data (method 1). Peak and mean power applied to the system (barbell + lifter) was obtained from 3 other methods: (a) using GRF-time data (method 2), (b) using barbell displacement-time data (method 3), and (c) using both barbell displacement-time data and GRF-time data (method 4). The peak power values (W) obtained from methods 1, 2, 3, and 4 were (mean +/- SD) 1,644 +/- 295, 3,079 +/- 638, 3,821 +/- 917, and 4,017 +/- 833 in hang power clean and 1,184 +/- 115, 3,866 +/- 451, 3,567 +/- 494, and 4,427 +/- 557 in weighted jump squat. There were significant differences between power output values obtained from method 1 vs. methods 2, 3, and 4, as well as method 2 vs. methods 3 and 4. The power output applied to the barbell and that applied to the system was significantly correlated (r = 0.65-0.81). As a practical application, it is important to understand the characteristics of each method and consider how power output should be measured during the hang power clean and the weighted jump squat.
TL;DR: The effects of eccentric exercise on muscle injury prevention and athletic performance are emerging areas of interest to researchers and of particular interest are the adaptations that occur after a single bout, or multiple bouts of eccentric Exercise.
Abstract: The effects of eccentric exercise on muscle injury prevention and athletic performance are emerging areas of interest to researchers. Of particular interest are the adaptations that occur after a single bout, or multiple bouts of eccentric exercise. It has been established that after certain types of eccentric exercise, the optimum length of tension development in muscle can be shifted to longer muscle lengths. Altering the length-tension relationship can have a profound influence on human movements. It is thought that the length-tension relationship is influenced by the structural makeup of muscle. However, the mechanism responsible for the shift in optimum length is not readily agreed upon. Despite the conflict, several studies have reported a shift in optimum length after eccentric exercise. Unfortunately, very few of these studies have been randomised, controlled training studies, and the duration of the shift has not yet been established. Nonetheless, this adaptation may result in greater structural stability at longer muscle lengths and consequently may have interesting implications for injury prevention and athletic performance. Both contentions remain relatively unexplored and provide the focus of this review.
TL;DR: It is suggested that changes in running form and compromised muscle function due to muscle damage contribute to the reduction in running economy for 3 days after downhill running.
Abstract: In this study, we examined the time course of changes in running economy following a 30-min downhill (-15%) run at 70% peak aerobic power (VO2peak). Ten young men performed level running at 65, 75, and 85% VO2peak (5 min for each intensity) before, immediately after, and 1 - 5 days after the downhill run, at which times oxygen consumption (VO2), minute ventilation, the respiratory exchange ratio (RER), heart rate, ratings of perceived exertion (RPE), and blood lactate concentration were measured. Stride length, stride frequency, and range of motion of the ankle, knee, and hip joints during the level runs were analysed using high-speed (120-Hz) video images. Downhill running induced reductions (7 - 21%, P < 0.05) in maximal isometric strength of the knee extensors, three- to six-fold increases in plasma creatine kinase activity and myoglobin concentration, and muscle soreness for 4 days after the downhill run. Oxygen consumption increased (4 - 7%, P < 0.05) immediately to 3 days after downhill running. There were also increases (P < 0.05) in heart rate, minute ventilation, RER, RPE, blood lactate concentration, and stride frequency, as well as reductions in stride length and range of motion of the ankle and knee. The results suggest that changes in running form and compromised muscle function due to muscle damage contribute to the reduction in running economy for 3 days after downhill running.
TL;DR: Tea drinking is associated with preservation of hip structure in elderly women, providing further evidence of the beneficial effects of tea consumption on the skeleton.
TL;DR: This paper presents an update of the WHO guide by the Task Force on Suicide in Prisons, created by the International Association for Suicide Prevention, and some international comparisons of suicide prevention services in correctional facilities.
Abstract: In 2000 the Department of Mental Health of the World Health Organization (WHO) published a guide named Preventing Suicide. A Resource for Prison Officers as part of the WHO worldwide initiative for the prevention of suicide. In 2007 there are new epidemiological data on prison suicide, a more detailed discussion of risk factors accounting for the generally higher rate of suicide in correctional settings in comparison to the general population, and several strategies for developing screening instruments. As a first step, this paper presents an update of the WHO guide by the Task Force on Suicide in Prisons, created by the International Association for Suicide Prevention. A second paper, by the same Task Force, will present some international comparisons of suicide prevention services in correctional facilities.
TL;DR: Effects of video modeling on generalized independent toy play of two boys with autism produced increases in appropriate play and decreases in repetitive play, but generalized play was observed only with the related toys.
Abstract: The present study examined effects of video modeling on generalized independent toy play of two boys with autism. Appropriate and repetitive verbal and motor play were measured, and intermeasure relationships were examined. Two single-participant experiments with multiple baselines and withdrawals across toy play were used. One boy was presented with three physically unrelated toys, whereas the other was presented with three related toys. Video modeling produced increases in appropriate play and decreases in repetitive play, but generalized play was observed only with the related toys. Generalization may have resulted from variables including the toys' common physical characteristics and natural reinforcing properties and the increased correspondence between verbal and motor play.
TL;DR: In this paper, the authors present an introduction to a new body of work on the physical and biological dynamics of the Leeuwin Current and its eddies, collected in this Special Issue of Deep-Sea Research II, including several modelling efforts aimed at understanding LC dynamics and eddy generation, and the first detailed field investigations of the biological oceanography of LC mesoscale eddies.
Abstract: The Leeuwin Current (LC) is an anomalous poleward-flowing eastern boundary current that carries warm, low-salinity water southward along the coast of Western Australia. We present an introduction to a new body of work on the physical and biological dynamics of the LC and its eddies, collected in this Special Issue of Deep-Sea Research II, including (1) several modelling efforts aimed at understanding LC dynamics and eddy generation, (2) papers from regional surveys of primary productivity and nitrogen uptake patterns in the LC, and (3) the first detailed field investigations of the biological oceanography of LC mesoscale eddies. Key results in papers collected here include insight into the source regions of the LC and the Leeuwin Undercurrent (LUC), the energetic interactions of the LC and LUC, and their roles in the generation of warm-core (WC) and cold-core (CC) eddies, respectively. In near-shore waters, the dynamics of upwelling were found to control the spatio-temporal variability of primary production, and important latitudinal differences were found in the fraction of production driven by nitrate (the f-ratio). The ubiquitous deep chlorophyll maximum within LC was found to be a significant contributor to total water column production within the region. WC eddies including a single large eddy studied in 2000 contained relatively elevated chlorophyll a concentrations thought to originate at least in part from the continental shelf/shelf break region and to have been incorporated during eddy formation. During the Eddies 2003 voyage, a more detailed study comparing the WC and CC eddies illuminated more mechanistic details of the unusual dynamics and ecology of the eddies. Food web analysis suggested that the WC eddy had an enhanced "classic" food web, with more concentrated mesozooplankton and larger diatom populations than in the CC eddy. Finally, implications for fisheries management are addressed.
TL;DR: Three recommendations for moving beyond the paradox are discussed—the provision of improved grief education for service providers, the bereaved, and the wider community; the conduct of research that emphasizes the context of grief and is relevant to service provision; and the examination of current grief interventions.
Abstract: A key theme in the bereavement literature is the recognition that every grief experience is unique and dependent on many variables, such as the circumstances of the death, characteristics of the bereaved individual, their relationship with the deceased, the provision and availability of support, and a myriad of sociocultural factors. Concurrently, there are corresponding efforts to define "normal" grief and delineate it from "complicated" grief experiences. The discord between these two potentially opposing statements remains a paradox evident within the three major tensions within the thanatological literature--the dominance of grief theories, the medicalization of grief, and the efficacy of grief interventions. Three recommendations for moving beyond the paradox are discussed--the provision of improved grief education for service providers, the bereaved, and the wider community; the conduct of research that emphasizes the context of grief and is relevant to service provision; and the examination of current grief interventions.
TL;DR: Thesession RPE method appears to be effective in monitoring different types of resistance training, and session RPE after 30 min was a better indicator of the overall resistance sessions than average RPE.
Abstract: Purpose: To evaluate the effectiveness of session rating of perceived exertion (RPE) to measure effort during different types of resistance training. Method: Fifteen male subjects (age 26.7 ± 4.3 years) performed 3 protocols. All protocols consisted of same 5 exercises but with different intensities, rest periods, and numbers of repetitions. One-repetition maximum (1-RM) was defined as the maximal amount of weight that an individual could lift 1 time without support. The strength protocol included 3 sets of 5 repetitions at 90% of 1-RM with 3 minutes rest between. The hypertrophy session included 3 sets of 10 repetitions at 70% with 1 minute of rest, and the power session included 3 sets of 5 repetitions at 50% with 3 minutes of rest. Session RPE is a modification of the standard RPE scale. Session and standard RPE were measured after the completion of each set and 30 minutes postexercise, respectively. Results: Results showed a difference between both the 2 RPE values of the strength and hypertrophy prot...
TL;DR: Common morphological and physiological ADT-related side effects or ‘Androgen Deprivation and Sarcopenia-Related Disorders’ are discussed and the existing clinical trials incorporating physical exercise in prostate cancer patients receiving active therapy are discussed.
Abstract: Side effects accompanying androgen deprivation therapy (ADT), including sarcopenia, loss of bone mass and reduction in muscle strength, can compromise physical function, particularly in older patients. Exercise, specifically resistance training, may be an effective and cost-efficient strategy to limit or even reverse some of these adverse effects during and following therapy. In this review, we discuss common morphological and physiological ADT-related side effects or 'Androgen Deprivation and Sarcopenia-Related Disorders' and the existing clinical trials incorporating physical exercise in prostate cancer patients receiving active therapy. Further, training concepts and guidelines are provided for prescribing resistance exercise programs for this population.
TL;DR: In this paper, a comparison of tourism growth, country risk returns and their associated volatilities (or uncertainty) for two small island tourism economies (SITEs) namely Cyprus and Malta is provided.
TL;DR: The main purpose of this paper is to understand public‐sector outsourcing in Australia, to examine the linkage between IS/IT outsourcing and the use of evaluation methodologies, and to identify issues that are critical in evaluating and managing IS/ IT outsourcing contracts in public‐ sector organizations.
Abstract: Purpose – The main purpose of this paper is threefold: to understand public‐sector outsourcing in Australia; to examine the linkage between IS/IT outsourcing and the use of evaluation methodologies; and to identify issues that are critical in evaluating and managing IS/IT outsourcing contracts in public‐sector organizations.Design/methodology/approach – A survey of the top 500 Australian organizations and two in‐depth case studies of two Australian public‐sector organizations were conducted.Findings – Several key issues for IS/IT outsourcing were identified – problems in evaluating outsourcing contracts, embedded contract mentality, ability to manage contracts, and staff transition management.Practical implications – Outsourcing organizations need to implement changes carefully and assess their in‐house capabilities. They also need to fully understand and apply the IS/IT investment evaluation and benefits realization processes. In order to reach the magnitude of improvements ascribed to IS/IT outsourcing ...
TL;DR: It is indicated that peak power and the timing of power output in the jump squat varies according to the measurement technique utilized, and the 1-LPT methodology is not a valid means of determining powerOutput in thejump squat.
Abstract: The purpose of this study was to investigate the validity of power measurement techniques during the jump squat (JS) utilizing various combinations of a force plate and linear position transducer (LPT) devices. Nine men with at least 6 months of prior resistance training experience participated in this acute investigation. One repetition maximums (1RM) in the squat were determined, followed by JS testing under 2 loading conditions (30% of 1RM [JS30] and 90% of 1RM [JS90]). Three different techniques were used simultaneously in data collection: (a) 1 linear position transducer (1-LPT); (b) 1 linear position transducer and a force plate (1-LPT + FP); and (c) 2 linear position transducers and a force place (2-LPT + FP). Vertical velocity-, force-, and power-time curves were calculated for each lift using these methodologies and were compared. Peak force and peak power were overestimated by 1-LPT in both JS30 and JS90 compared with 2-LPT + FP and 1-LPT + FP (p
