Cryotherapy and joint position sense in healthy participants: a systematic review

Objective: To (1) search the English-language literature for original research addressing the effect of cryotherapy on joint position sense (JPS) and (2) make recommendations regarding how soon healthy athletes can safely return to participation after cryotherapy. Data Sources: We performed an exhaustive search for original research using the AMED, CINAHL, MEDLINE, and SportDiscus databases from 1973 to 2009 to gather information on cryotherapy and JPS. Key words used were cryotherapy and proprioception, cryotherapy and joint position sense, cryotherapy, and proprioception. Study Selection: The inclusion criteria were (1) the literature was written in English, (2) participants were human, (3) an outcome measure included JPS, (4) participants were healthy, and (5) participants were tested immediately after a cryotherapy application to a joint. Data Extraction: The means and SDs of the JPS outcome measures were extracted and used to estimate the effect size (Cohen d) and associated 95% confidence intervals for comparisons of JPS before and after a cryotherapy treatment. The numbers, ages, and sexes of participants in all 7 selected studies were also extracted. Data Synthesis: The JPS was assessed in 3 joints: ankle (n 5 2), knee (n 5 3), and shoulder (n 5 2). The average effect size for the 7 included studies was modest, with effect sizes ranging from 20.08 to 1.17, with a positive number representing an increase in JPS error. The average methodologic score of the included studies was 5.4/10 (range, 5–6) on the Physiotherapy Evidence Database scale. Conclusions: Limited and equivocal evidence is available to address the effect of cryotherapy on proprioception in the form of JPS. Until further evidence is provided, clinicians should be cautious when returning individuals to tasks requiring components of proprioceptive input immediately after a cryotherapy treatment.

Evidence based practice

An integral part of teaching and a principle underpinning professional practice in the early years is the importance of reflecting on and researching our own practice. For example, in Australia, the Early Years Learning Framework: Belonging, Being and Becoming identifies “ongoing learning and reflective practice” (DEEWR, 2009, p. 13) as one of the five principles distilled from theories and research evidence that underpin professional practice in the early years. Recognising teaching as encompassing the role of researching pedagogical practice highlights that teaching is not simply practical or procedural but requires intellectual work. This chapter details evidence based practice (EBP) in early years education and highlights four questions: 1. What is evidence based practice?; 2. What evidence do I draw on?; 3. How might I discern relevant evidence?; and 4. What is my part in generating research evidence?

UK pre-pack reforms : pause for thought in Australia?

On 31 March 2011 the UK Government announced new measures to regulate the use of pre-packaged sales in administration. The legislation is not expected until later in 2011, but the announcement heralds a shift in regulatory attitudes towards pre-packs in the UK which should give all local pre-pack advocates pause for thought when considering the merits of embracing the procedure in Australia. In the Jan-March 2011 edition of the Australian Insolvency Journal, an interesting article by Nicholas Crouch and Shabnam Amirbeaggi extolled the virtues of pre-packs and called for “legislative reform to embrace pre-packs” in Australia. By way of reply (and in a spirit of constructive debate) this article respectfully contends that while pre-packs certainly have their place in preserving business value in certain circumstances, Australia should be careful not to sleepwalk into adopting a procedure which legitimises phoenixing at the expense of creditor confidence and participation in our insolvency regime.

A review of system safety failure probability objectives for Unmanned Aircraft Systems

Unmanned Aircraft Systems (UAS) are one of a number of emerging aviation sectors. Such new aviation concepts present a significant challenge to National Aviation Authorities (NAAs) charged with ensuring the safety of their operation within the existing airspace system. There is significant heritage in the existing body of aviation safety regulations for Conventionally Piloted Aircraft (CPA). It can be argued that the promulgation of these regulations has delivered a level of safety tolerable to society, thus justifying the “default position” of applying these same standards, regulations and regulatory structures to emerging aviation concepts such as UAS. An example of this is the proposed “1309” regulation for UAS, which is based on the 1309 regulation for CPA. However, the absence of a pilot on-board an unmanned aircraft creates a fundamentally different risk paradigm to that of CPA. An appreciation of these differences is essential to the justification of the “default position” and in turn, to ensure the development of effective safety standards and regulations for UAS. This paper explores the suitability of the proposed “1309” regulation for UAS. A detailed review of the proposed regulation is provided and a number of key assumptions are identified and discussed. A high-level model characterising the expected number of third party fatalities on the ground is then used to determine the impact of these assumptions. The results clearly show that the “one size fits all” approach to the definition of 1309 regulations for UAS, which mandates equipment design and installation requirements independent of where the UAS is to be operated, will not lead to an effective management of the risks.

Enabling innovation and facilitating learning in kifs: the role of HRM practices

The aim of this paper is to contribute to our understanding of the link between HR practices, learning orientation and types of innovation in knowledge-intensive firms (KIFs). To this end, we first compiled a comprehensive overview of the existing literature on HR practices aimed at supporting innovation. On the basis of this literature, we then collected and analyzed data from a qualitative study of 19 Danish KIFs recognized for their innovation performance, focusing on links between the HR practices they use to support exploratory and exploitive learning behaviors to enhance incremental and/or radical innovation. The findings from this study demonstrate that KIFs utilize a range of HR practices that enable different learning orientations, based on the type of innovation compatible with their organizational goals.

Early years activities for NLNW 2012 - Pearl Barley & Charlie Parsley

This Early Years unit is designed to engage students in a sequence of activities that use a range of literacies which explore feelings, friendships and personality traits. The text, Pearl Barley and Charlie Parsley, is the focus of this unit. Suggested activities promote participation through simple and effective strategies, using technology, process drama, graphic ogranisers and critical literacy. This unit allows for flexibility so teachers can select activities that best suit time, resources and students' needs and interests. Students are asked to make connections between the text and their own friendships, understanding that the best of friends can be different in almost every way.

Brand loyalty in the Australian wine industry

Consumers are increasingly exposed to a wider range of wine brands as the industry is becoming vastly competitive. Using data from Australian wine consumers, the authors empirically test a model of antecedents of wine brand loyalty. The findings of this study show that wine knowledge and wine experience influence wine brand loyalty indirectly through wine brand trust and wine brand satisfaction. In addition, it is demonstrated that consumer satisfaction with a wine brand is the strongest driver of wine brand loyalty.

When non-significance may be significant : lessons learned from a study of the development, implementation and evaluation of a fleet risk assessment tool

This paper reports on the development and implementation of a self-report risk assessment tool that was developed in an attempt to increase the efficacy of crash prediction within Australian fleet settings. This study forms a part of a broader program of research into work related road safety and identification of driving risk. The first phase of the study involved a series of focus groups being conducted with 217 professional drivers which revealed that the following factors were proposed to influence driving performance: Fatigue, Knowledge of risk, Mood, Impatience and frustration, Speed limits, Experience, Other road users, Passengers, Health, and Culture. The second phase of the study involved piloting the newly developed 38 item Driving Risk Assessment Scale - Work Version (DRAS-WV) with 546 professional drivers. Factor analytic techniques identified a 9 factor solution that was comprised of speeding, aggression, time pressure, distraction, casualness, awareness, maintenance, fatigue and minor damage. Speeding and aggressive driving manoeuvres were identified to be the most frequent aberrant driving behaviours engaged in by the sample. However, a series of logistic regression analyses undertaken to determine the DRAS-WV scale’s ability to predict self-reported crashes revealed limited predictive efficacy e.g., 10% of crashes. This paper outlines proposed reasons for this limited predictive ability of the DRAS-WV as well as provides suggestions regarding the future of research that aims to develop methods to identify “at risk” drivers.

Fatalism and its implications for risky road use and receptiveness to safety messages : a qualitative investigation in Pakistan

Given the increasing vehicle numbers and expanding road construction in developing countries, the importance of safe road user behaviour is critical. Road traffic crashes (RTC) are a significant problem in Pakistan, however the factors that contribute to RTC in Pakistan are not well-researched. Fatalistic beliefs are a potential barrier to the enhancement of road safety, especially participation in health-promoting and injury prevention behaviours, and also contribute to risk-taking. Fatalistic beliefs relating to road safety have been found in some developing countries, although again research is scarce and indicates that the nature and extent of fatalism differs in each country. Qualitative research was undertaken with a range of drivers, religious orators, police and policy makers to explore associations between fatalism, risky road use and associated issues. Findings indicate that fatalistic beliefs are pervasive in Pakistan, are strongly linked with religion, present a likely barrier to road safety messages and contribute to risky road use. Fatalism appears to be a default attribution of RTC and the intensity of belief in fate surpasses the kinds of fatalism noted in the limited existing literature. These findings have importance to developing road safety countermeasures in countries where fatalistic beliefs are strong.

Provincialising Perth? : Satellite television and the Chinese in Perth

Relocated people habitually seek the familiar within their new social milieus as a means of easing their transition into ways strange and alien. However, from networks and food to everyday customs, efforts to hold on to such home comforts are often viewed with a measure of hostile disdain and regarded as preludes to the formation of ethnic enclaves. Through a pilot study on the access of satellite television by mainland Chinese migrants in Perth, Western Australia, this chapter seeks to shed some light on how migrants understand and employ these comforting strategies and how Chinese-Australians are using technology to achieve a sense of sanctuary from the views and habits of Australians while (re)constructing and articulating multiple belongings in their new homes.
