Objectives. To compare 12-month falls recall with falls reported prospectively on daily falls calendars in a clinical trial of women aged ≥70 years. Methods. 2,096 community-dwelling women at high risk of falls and/or fracture completed a daily falls calendar and standardised interviews when falls were recorded, for 12 months. Data were compared to a 12-month falls recall question that categorised falls status as “no falls,” “a few times,” “several,” and “regular” falls. Results. 898 (43%) participants reported a fall on daily falls calendars of whom 692 (77%) recalled fall(s) at 12 months. Participants who did not recall a fall were older (median 79.3 years versus 77.8 years, ). Smaller proportions of fallers who sustained an injury or accessed health care failed to recall a fall (all ). Among participants who recalled “no fall,” 85% reported zero falls on daily calendars. Few women selected falls categories of “several times” or “regular” (4.1% and 0.4%, resp.) and the sensitivity of these categories was low (30% to 33%). Simply categorising participants into fallers or nonfallers had 77% sensitivity and 94% specificity. Conclusion. For studies where intensive ascertainment of falls is not feasible, 12-month falls recall questions with fewer responses may be an acceptable alternative.

In this essay I discuss how a familiar costume element in Javanese court dance, a long piece of patterned cloth known as the sampur, functions poetically through the ways it is used by the dancer. I elaborate on eight categories of use of the sampur, primarily from the point of view of a Western dancer first encountering the techniques of working with the scarf. I draw on scholars and other commentators to discuss the many dimensions of meaning embodied by these uses. The sampur emerges as a dance element rich in virtuosic potential and nuance, and resonant with numerous dimensions of cultural values.

STUDY OBJECTIVE: Measurement of acetylcholinesterase (AChE) is recommended in the management of organophosphorus poisoning, which results in 200,000 deaths worldwide annually. The Test-mate ChE 400 is a portable field kit designed for detecting occupational organophosphorus exposure that measures RBC AChE and plasma cholinesterase (PChE) within 4 minutes. We evaluate Test-mate against a reference laboratory test in patients with acute organophosphorus self-poisoning. METHODS: This was a cross-sectional comparison study of 14 patients with acute organophosphorus poisoning between May 2007 and June 2008. RBC AChE and PChE were measured in 96 and 91 samples, respectively, with the Test-mate ChE field kit and compared with a reference laboratory, using the limits of agreement method (Bland and Altman), κ statistics, and Spearman's correlation coefficients. RESULTS: There was good agreement between the Test-mate ChE and the reference laboratory for RBC AChE. The mean difference (Test-mate-reference) was -0.62 U/g hemoglobin, 95% limits of agreement -10.84 to 9.59 U/g hemoglobin. Good agreement was also observed between the categories of mild, moderate, and severe RBC AChE inhibition (weighted κ 0.85; 95% confidence interval [CI] 0.83 to 0.87). Measurement of PChE also showed good agreement, with a mean difference (Test-mate-reference) of +0.06 U/mL blood, 95% limits of agreement -0.41 to 0.53 U/mL blood. Spearman's correlation coefficients were 0.87 (95% CI 0.81 to 0.91) for RBC AChE and 0.76 (95% CI 0.66 to 0.84) for PChE. Analysis for within-subject correlation of subjects did not change the limits of agreement. CONCLUSION: The Test-mate ChE field kit reliably provides rapid measurement of RBC AChE in acute organophosphorus poisoning.

CONTEXT: Accelerometer peak impact accelerations are being used to measure player physical demands in contact sports. However, their accuracy to do so has not been ascertained. PURPOSE: To compare peak-impact-acceleration data from an accelerometer contained in a wearable tracking device with a 3-dimensional motion-analysis (MA) system during tackling and bumping. METHODS: Twenty-five semielite rugby athletes wore a tracking device containing a 100-Hz triaxial accelerometer (MinimaxX S4, Catapult Innovations, Australia). A single retroreflective marker was attached to the device, with its position recorded by a 12-camera MA system during 3 physical-collision tasks (tackle bag, bump pad, and tackle drill; N = 625). The accuracy, effect size, agreement, precision, and relative errors for each comparison were obtained as measures of accelerometer validity. RESULTS: Physical-collision peak impact accelerations recorded by the accelerometer overestimated (mean bias 0.60 g) those recorded by the MA system (P < .01). Filtering the raw data at a 20-Hz cutoff improved the accelerometer's relationship with MA data (mean bias 0.01 g; P > .05). When considering the data in 9 magnitude bands, the strongest relationship with the MA system was found in the 3.0-g or less band, and the precision of the accelerometer tended to reduce as the magnitude of impact acceleration increased. Of the 3 movements performed, the tackle-bag task displayed the greatest validity with MA. CONCLUSIONS: The findings indicate that the MinimaxX S4 accelerometer can accurately measure physical-collision peak impact accelerations when data are filtered at a 20-Hz cutoff frequency. As a result, accelerometers may be useful to measure physical collisions in contact sports.

Background:
Little is known regarding the symptoms of fatigue that maritime pilots experience during shift work. Moreover, the strategies these individuals use to cope with the onset of fatigue are also unknown. The current study explored the symptoms of fatigue and coping strategies experienced by maritime pilots when on-shift.

Material and methods:
Fifty maritime pilots were recruited via an advertisement in the national association’s quarterly newsletter (Mage = 51.42; SD = 9.81). Participants responded to a modified version of the questionnaire used with aviation pilots that assessed overall fatigue, and the symptoms pilots associated with fatigue on duty. Methods pilots used to cope with fatigue before shift and when on the bridge were also assessed.

Results:
There were significant effects for pilot vitality on 4 categories of fatigue: cognitive dysfunction; emotional disturbance; mean physical effects; and sleepiness. There were no significant effects for vitality on any of the self-reported coping strategy factors.

Conclusions:
The findings indicated that maritime pilots experience a variety of physical, behavioural, and cognitive fatigue symptoms when on shift. Some of these symptoms are similar to those reported by aviation pilots. However, unlike aviation pilots, maritime pilots reported utilising self-sufficient coping strategies to deal with the experience of fatigue.

In response to growing demand for ecosystem-level risk assessment in biodiversity conservation, and rapid proliferation of locally tailored protocols, the IUCN recently endorsed new Red List criteria as a global standard for ecosystem risk assessment. Four qualities were sought in the design of the IUCN criteria: generality; precision; realism; and simplicity. Drawing from extensive global consultation, we explore trade-offs among these qualities when dealing with key challenges, including ecosystem classification, measuring ecosystem dynamics, degradation and collapse, and setting decision thresholds to delimit ordinal categories of threat. Experience from countries with national lists of threatened ecosystems demonstrates well-balanced trade-offs in current and potential applications of Red Lists of Ecosystems in legislation, policy, environmental management and education. The IUCN Red List of Ecosystems should be judged by whether it achieves conservation ends and improves natural resource management, whether its limitations are outweighed by its benefits, and whether it performs better than alternative methods. Future development of the Red List of Ecosystems will benefit from the history of the Red List of Threatened Species which was trialed and adjusted iteratively over 50 years from rudimentary beginnings. We anticipate the Red List of Ecosystems will promote policy focus on conservation outcomes in situ across whole landscapes and seascapes.

OBJECTIVE: To examine Corporate Social Responsibility (CSR) tactics by identifying the key characteristics of CSR strategies as described in the corporate documents of selected 'Big Food' companies. METHODS: A mixed methods content analysis was used to analyse the information contained on Australian Big Food company websites. Data sources included company CSR reports and web-based content that related to CSR initiatives employed in Australia. RESULTS: A total of 256 CSR activities were identified across six organisations. Of these, the majority related to the categories of environment (30.5%), responsibility to consumers (25.0%) or community (19.5%). CONCLUSIONS: Big Food companies appear to be using CSR activities to: 1) build brand image through initiatives associated with the environment and responsibility to consumers; 2) target parents and children through community activities; and 3) align themselves with respected organisations and events in an effort to transfer their positive image attributes to their own brands. IMPLICATIONS: Results highlight the type of CSR strategies Big Food companies are employing. These findings serve as a guide to mapping and monitoring CSR as a specific form of marketing.

PURPOSE: Both moderate-to-vigorous physical activity (MVPA) and sedentary behavior can be associated with adult adiposity. Much of the relevant evidence is from cross-sectional studies or from prospective studies with relevant exposure measures at a single time point prior to weight gain or incident obesity. This study examined whether changes in MVPA and television (TV) viewing time are associated with subsequent changes in waist circumference, using data from three separate observation points in a large population-based prospective study of Australian adults. METHODS: Data were obtained from the Australian Diabetes, Obesity and Lifestyle study collected in 1999-2000 (baseline), 2004-05 (Wave 2), and 2011-12 (Wave 3). The study sample consisted of adults aged 25 to 74 years at baseline who also attended site measurement at three time points (n=3261). Multilevel linear regression analysis examined associations of initial five-year changes in MVPA and TV viewing time (from baseline to Wave 2) with 12-year change in waist circumference (from baseline to Wave 3), adjusting for well-known confounders. RESULTS: As categorical predictors, increases in MVPA significantly attenuated increases in waist circumference (p for trend< 0.001). TV viewing time change was not significantly associated with changes in waist circumference (p for trend =0.06). Combined categories of MVPA and TV viewing time changes were predictive of waist circumference increases; compared to those who increased MVPA and reduced TV viewing time, those who reduced MVPA and increased TV viewing time had a 2cm greater increase in waist circumference (p=0.001). CONCLUSION: Decreasing MVPA emerged as a significant predictor of increases in waist circumference. Increasing TV viewing time was also influential, but its impact was much weaker than MVPA.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

Mathematical reasoning has been emphasised as one of the key proficiencies for mathematics in the Australian curriculum since 2011 and in the Canadian curriculum since 2007. This study explores primary teachers’ perceptions of mathematical reasoning at a time of further curriculum change. Twenty-four primary teachers from Canada and Australia were interviewed after engagement in the first stage of the Mathematical Reasoning Professional Learning Program incorporating demonstration lessons focused on reasoning conducted in their schools. Phenomenographic analysis of interview transcripts exploring variation in the perceptions of mathematical reasoning held by these teachers revealed seven categories of description based on four dimensions of variation. The categories delineate the different perceptions of mathematical reasoning expressed by the participants of this study. The resulting outcome space establishes a framework that facilitates tracking of growth in primary teachers’ awareness of aspects of mathematical reasoning.

Purpose: To review the literature relating to use of social media by people with a traumatic brain injury (TBI), specifically its use for social engagement, information exchange or rehabilitation.

Method: A systematic review with a qualitative meta-synthesis of content themes was conducted. In June 2014, 10 databases were searched for relevant, peer-reviewed research studies in English that related to both TBI and social media.

Results
: Sixteen studies met the inclusion criteria, with Facebook™ and Twitter™ being the most common social media represented in the included studies. Content analysis identified three major categories of meaning in relation to social media and TBI: (1) risks and benefits; (2) barriers and facilitators; and (3) purposes of use of social media. A greater emphasis was evident regarding potential risks and apparent barriers to social media use, with little focus on facilitators of successful use by people with TBI.

Conclusions:
Research to date reveals a range of benefits to the use of social media by people with TBI however there is little empirical research investigating its use. Further research focusing on ways to remove the barriers and increase facilitators for the use of social media by people with TBI is needed. Implications for Rehabilitation: Communication disabilities following traumatic brain injury (TBI) can be wide-ranging in scope and social isolation with loss of friendships after TBI is common. For many people, social media is rapidly becoming a usual part of everyday communication and its use has the potential to increase communication and social participation for people with TBI.There is emerging evidence and commentary regarding the perceived benefits and risks, barriers and facilitators and purposes of use of social media within the TBI population.Risks associated with using social media, and low accessibility of social media sites, form barriers to its use. Facilitators for social media use in people with TBI include training the person with TBI and their communication partners in ways to enjoy and use social media safely.There is minimal rigorous evaluation of social media use by people with TBI and scant information regarding social media use by people with communication disabilities after TBI. Further investigation is needed into the potential benefits of social media use on communication, social participation and social support with the aim of reducing social isolation in people with TBI.

Purpose – The focus of this paper is on the benefits that may eventuate through new mechanisms of production and distribution. As we enter the twenty-first century, the nature of the book and the structure of the industry which produces it are undergoing radical transformation, as developments in information technology offer new mechanisms for production and distribution. Most of the discussion of these changes is conducted from the perspective of what has been lost through these changes. Design/methodology/approach – This paper reviews the history of the book from the perspective of the disruptive effects of the changes in production technology and impact on the roles involved in production, distribution and reading of books. Darnton’s Communication Circuit is updated to predict future limiting factors and opportunities for participation. Findings – The evolution of the book has seen successive categories of workers involved in book production supplanted by the adoption of new technology. The updated Darnton’s model suggests that the roles involved in the production and distribution of the book will, however, be supplanted in favour of authors and readers of the book in the future. Social implications – The predicted changes will alter the roles of authors and book users. Originality/value – This paper suggests a novel approach to the discussion of the future of book publication and suggests future developments.

Purpose– Acknowledgement of the social impact created by organisations has become an increasingly frequent discussion among practitioners. The importance of such value creation cannot be understated, yet in an increasingly competitive funding environment, the need to articulate “true” value is paramount. The purpose of this paper is to examine how Australian and US managers of non-profit organisations (NPOs) and foundations view the measurement of the social impact of NPOs.Design/methodology/approach– The paper includes 19 in-depth interviews of non-profit professionals in the USA and Australia. Respondents included non-profit managers, foundation managers and consultants in both countries.Findings– The in-depth interviews found that in both countries respondents generally agreed that objective measures of impact are desirable, but recognised the difficulties in developing objective assessment frameworks enabling comparisons across the non-profit sector. These difficulties, as well as the implications for developing assessments of social value for NPOs, are discussed. This paper demonstrates that there is an opportunity to reposition reporting expectations. The NPO sector can pool together and build on each other’s strengths and market their outcomes as a collective entity. A sector-wide approach provides potential for much needed within-sector mentoring and will showcase the rich and varied outcomes generated by NPOs.Originality/value– This research compares viewpoints in two Western countries, thus offering at least an exploratory examination of social impact assessment from an international perspective. Additionally, this research shows commonalities in terms of what is valued and what is most difficult for non-profits when determining social impact.

We outline possible actions to be adopted by the European Union to ensure a better share of total coffee revenues to producers in developing countries. The way to this translates, ultimately, in producers receiving a fair price for the commodity they supply, i.e., a market price that results from fair market conditions in the whole coffee producing chain. We plead for proposals to take place in the consuming countries, as market conditions in the consuming-countries side of the coffee producing chain are not fair; market failures and ingenious distortions are responsible for the enormous asymmetry of gains in the two sides. The first of three proposals for consumer government supported actions is to help in the creation of domestic trading companies for achieving higher export volumes. These tradings would be associated to roasters that, depending on the final product envisaged, could perform the roasting in the country and export the roasted – and sometimes ground – coffee, breaking the increasing importers-exporters verticalisation. Another measure would be the systematic provision of basic intelligence on the consuming markets. Statistics of the quantities sold according to mode of consumption, by broad “categories of coffee” and point of sale, could be produced for each country. They should be matched to the exports/imports data and complemented by (aggregate) country statistics on the roasting sector. This would extremely help producing countries design their own market and producing strategies. Finally, a fund, backed by a common EU tax on roasted coffee – created within the single market tax harmonisation programme, is suggested. This European Coffee Fund would have two main projects. Together with the ICO, it would launch an advertising campaign on coffee in general, aimed at counterbalancing the increasing “brandification” of coffee. Basic information on the characteristics of the plant and the drink would be passed, and the effort could be extended to the future Eastern European members of the Union, as a further assurance that EU processors would not have a too privileged access to these new markets. A quality label for every coffee sold in the Union could complement this initiative, helping to create a level playing field for products from outside the EU. A second project would consist in a careful diversification effort, to take place in selected producing countries.

O estudo teve por objetivo identificar quais os fatores que provocam a motivação dos Peritos Criminais Federais das Unidades Técnico-Científicas da Polícia Federal na Bahia no desenvolvimento de suas atividades. Para isso, efetuou-se uma pesquisa descritiva, explicativa, bibliográfica e de campo. Foram realizadas entrevistas individuais e semiabertas, assim como aplicada a técnica de construção de desenhos, com todos os Peritos Criminais Federais lotados na Bahia, o que totaliza 35 servidores. Utilizando-se o método de análise de conteúdo, foram identificados 20 fatores que influenciam a motivação dos servidores pesquisados, sendo o “salário” o que mais incentivou na escolha do concurso para ingresso na instituição. Além do “salário”, o “trabalho em si”, o “desafio”, o “ambiente de trabalho” e o “aperfeiçoamento profissional” são os fatores que mais afetam positivamente a motivação desses Peritos Criminais na Polícia Federal. O “reconhecimento / valorização”, o “feedback / resultado do trabalho”, a “autonomia” e o “crescimento na carreira” foram considerados importantes para a motivação, porém, são fatores que para muitos dos entrevistados não estão presentes ou precisam melhorar na Polícia Federal. Os fatores que mais exercem influência negativa na motivação dos Peritos Criminais no órgão são a falta de “planejamento, organização”, a “burocracia, hierarquia rígida, estrutura fechada, excesso de controle”, a falta de “justiça” e a falta de “integração com outros componentes da Polícia Federal”. Completando a lista dos 20 fatores que se destacaram no estudo estão “meios e condições de trabalho”, “objetivos / metas a atingir”, “benefícios”, “prestígio / status / importância do órgão Polícia Federal”, “senso de responsabilidade”, “relacionamento com chefia” e “questões pessoais / família”. Sugere-se que pesquisa semelhante seja realizada com Peritos Criminais Federais lotados em outros estados e também com as demais categorias de servidores do órgão.
