- Description: Two studies examined the potential for negative mood induction through participating in suicidal ideation questionnaire research. Items immediately preceding mood state measures were hypothesized to influence mood state in a negative or positive direction, depending on their emotional content. Study 1 involved 129 adolescents. Mood state decreased nonsignificantly following items on suicidal-type ideation and significantly improved following a series of positive affect items. Study 2 followed up 71 of the original participants 3 years later using a briefer version of the original questionnaire. Here no significant differences in mood state were found at any measurement point. In both studies, the salience of items preceding the mood measure explained a significant proportion of variance in mood state. We concluded that negative mood induction effects were minimal. Ethical implications are discussed. © 2010 Springer Publishing Company.

- Description: Objective: To investigate whether being an immigrant is increase risk for AMI and stroke. Design and setting: A retrospective analysis of Victorian hospital admissions in 1996/97 and 2001/02 was conducted. Participants: AMI and stroke were defined using primary cases of admission of ICD-9-CM:‘P410’,ICD-10-AM:‘121’,‘122’and stroke ICD-9-CM‘P433’,’P436’,ICD- 10-AM ‘163’,‘164’diagnostic codes. Main outcome measured: Rate ratio (RR) of AMI and stroke were calculated using 1996 and 2001 Australian census data. Results: Male immigrants from three ethnic groups: USSR/Baltic (RR 3.91 95%CI 3.22,4.71), Southern Asia (RR 1.56 95%CI 1.31,1.85) and Middle East (RR 1.34 95%CI 1.10,1.63), consistently displayed higher risk for AMI (both years) than the Australian born cohort; while Southeast Asians (RR 0.51 95%CI 0.42,0.62) and Northeast Asians (RR 0.35 95%CI 0.24,0.50) were at lower risk. The findings for females were less consistent. North East Asian male and female immigrants (RR 0.57 95% CI 0.41, 0.76, RR 0.56 95%CI 0.41, 0.74), were consistently at lower risk for stroke than Australian born counterparts. Female immigrants from the Pacific Islands were consistently at higher risk (RR 1.52 95%CI 1.25, 1.84, RR 1.22 95%CI 0.98, 1.51) of stroke than Australian born women. Conclusion: A number of Non-Australian born adult males currently residing in Victoria are identified at increased risk of AMI, whereas few groups are at decreased risk, compared to Australian born males. North East Asian males and females were consistently at a lower risk for AMI and stroke than their Australian-born counterparts. However, Asia male and female immigrants are generally at a lower risk of stroke.

- Description: Objective: Despite the popularity of cricket at the junior community level, few studies have described injuries for this level of play. This study describes the epidemiology of cricket injuries in junior club cricket across three playing seasons to identify priorities for prevention. Design: Prospective on-field injury data collection during match observation of acute injuries. Pre and post observational evaluation of mandatory helmet wearing. Setting: The Sutherland Shire Junior Cricket Association, New South Wales, Australia during the 2002-03, 2003-04 and 2004-05 playing seasons. Participants: All junior teams (Under 8 (U8)-U16). Intervention: Compulsory headgear introduced for all batters before the 2004-05 season. Main outcome measures: Frequency of injury according to age level, grade of play and playing position, and injury rates per 100 registered players. Results: 155 injuries were reported. No U8 player sustained an injury, and injury frequency increased with age. Traditional cricket was associated with more injuries than modified cricket. At each age level, the most skilled players had the lowest frequency of injury. Overall, batting accounted for 49% of all injuries and 29% occurred when fielding; contact with a moving ball was responsible for 55% of injuries. The most commonly injured body region was the face (20%), followed by the hand (14%). In batters, the frequency of head/neck/facial injuries fell from 62% in 2002/03 to 35% in 2003-04 to just 4% in 2004-05 after headgear use was compulsory. Conclusions: Injury rates in junior players are low, but increase with age and level of play. Use of protective headgear, particularly by batters, leads to a significant reduction in injuries.

- Description: This paper examines and offers a critique of the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR), underlying principles and assumptions, and the nature and consequences of its nosological framework. The reason for this critique is to look at the rationale for some of the diagnostic categories and also why some categories are retained, including some of the long-standing diagnostic groups, such as schizophrenia. It is not the intention here to rehearse the problems of biological psychiatric thinking, nor argue the strengths and weaknesses of the DSM-IV-TR in its definitions and descriptions of particular syndromes and illnesses. The ideas presented here derive from a range of previous research that argued that the DSM-IV-TR colludes in a system of psychiatric care in which all people, by virtue of characteristically human foibles and idiosyncrasies, are potentially classifiable into a variety of diagnostic mental health categories. In the present study, it was argued that because of resource constraints, professional dispute, and public concern, the major criterion for attracting a formal diagnosis is not classifiability according to the DSM-IV-TR, but rather, that of 'social risk', defined in terms of risk to oneself and/or others and embodying obvious social control functions. Here, we expand and develop some of these ideas, and relate them more specifically to insights offered by critical or deconstructive psychology and the development of the forthcoming the DSM-V. © 2011 The Authors.

- Description: Objectives: Higher levels of depression have been documented among older adults who reside in an assisted living facility, compared with those who remain in their own homes. The aims of the current study were to test whether the relationship between housing type and depressive symptoms was mediated by a sense of belonging and whether housing type and sense of belonging interact to influence the depressive symptoms among older adults (moderation model).Method: A sample of 257 older adults who lived in their own homes and 166 older adults who lived in an assisted living facility completed the psychological subscale of the Sense of Belonging Instrument and the Center for Epidemiologic Studies Depression Scale.Results: Results showed that a sense of belonging partially mediated the relationship between housing type and depressive symptoms, such that living in a nursing home was associated with lower levels of belonging, and lower levels of belonging were, in turn, associated with higher levels of depressive symptoms. Residing in an assisted living facility was associated with depressive symptoms at low and average levels of belonging.Conclusion: Results highlight the need for more research on the role of sense of belonging as an influencing factor on depressive symptoms among institutionalised older adults for both theoretical and treatment goals.

- Description: Social media, such as social network sites and blogs, are increasingly being used as core or ancillary components of educational research, from recruitment to observation and interaction with researchers. However, this article reveals complex ethical dilemmas surrounding consent, traceability, working with children, and illicit activity that we have faced as education researchers for which there is little specific guidance in the literature. We believe that ethical research committees cannot, and should not, be relied upon as our ethical compass as they also struggle to deal with emerging technologies and their implications. Consequently, we call for researchers to report on the ethical dilemmas in their practice to serve as a guide for those who follow. We also recommend considering research ethics as an ongoing dialogical process in which the researcher, participants, and ethics committee work together in identifying potential problems as well as finding ways forward.

- Description: Despite the health benefits associated with children's sport participation, the occurrence of injury in this context is common. The extent to which sport injuries impact children's ongoing involvement in sport is largely unknown. Surveys have been shown to be useful for collecting children's injury and sport participation data; however, there are currently no published instruments which investigate the impact of injury on children's sport participation. This study describes the processes undertaken to assess the validity of two survey instruments for collecting self-reported information about child cricket and netball related participation, injury history and injury risk perceptions, as well as the reliability of the cricket-specific version. Face and content validity were assessed through expert feedback from primary and secondary level teachers and from representatives of peak sporting bodies for cricket and netball. Test-retest reliability was measured using a sample of 59 child cricketers who completed the survey on two occasions, 3-4 weeks apart. Based on expert feedback relating to face and content validity, modification and/or deletion of some survey items was undertaken. Survey items with low test-retest reliability (κ≤ 0.40) were modified or deleted, items with moderate reliability (κ=0.41-0.60) were modified slightly and items with higher reliability (κ≥ 0.61) were retained, with some undergoing minor modifications. This is the first survey of its kind which has been successfully administered to cricketers aged 10-16 years to collect information about injury risk perceptions and intentions for continued sport participation. Implications for its generalisation to other child sport participants are discussed. © 2010 Sports Medicine Australia.

- Description: Pressure ulcers are a common but preventable problem in hospitals. Implementation of best practice guideline recommendations can prevent ulcers from occurring. This 9-year cohort study reports prevalence data from point prevalence surveys during the observation period, and three practice metrics to assess implementation of best practice guideline recommendations: (i) nurse compliance with use of a validated pressure ulcer risk assessment and intervention checklist; (ii) accuracy of risk assessment scoring in usual-care nurses and experienced injury prevention nurses; and (iii) use of pressure ulcer prevention strategies. The prevalence of hospital-acquired pressure ulcers decreased following implementation of an evidence-based prevention programme from 12 center dot 6% (2 years preprogramme implementation) to 2 center dot 6% (6 years postprogramme implementation) (P < 0 center dot 001). Audits between 2003 and 2011 of 4368 patient medical records identified compliance with pressure ulcer prevention documentation according to best practice guidelines was high (>84%). A sample of 270 patients formed the sample for the study of risk assessment scoring accuracy and use of prevention strategies. It was found usual-care nurses under-estimated patients' risk of pressure ulcer development and under-utilised prevention strategies compared with experienced injury prevention nurses. Despite a significant reduction in prevalence of hospital-acquired pressure ulcers and high documentation compliance, use of prevention strategies could further be improved to achieve better patient outcomes. Barriers to the use of prevention strategies by nurses in the acute hospital setting require further examination. This study provides important insights into the knowledge translation of pressure ulcer prevention best practice guideline recommendations at The Northern Hospital.

Data was collected from 394 older community dwellers in Victoria, Australia using a baseline survey, and 245 of these participated in a follow-up survey one year later. Survey domains were drawn from constructs of relevant health behavior models. Results showed that the proportion of respondents who were currently participating in exercises to prevent falls at follow-up was 12% higher than at baseline (Wilcoxon p value<0.001). Twenty-nine percent reported they had changed their perceptions about falls and their risk of falls, with comments focused on threat appraisal. Forty-four percent reported having taken strategies to reduce their risk of falling, with comments based on implementation of different preventive strategies. Respondents who held favorable views towards exercises for the prevention of falls appear to change their behaviors that might address falls when participating in observational studies.

- Description: This paper examines regulatory responses to the presence of previously undetected and unlabelled nanoparticles in the Australian food system. Until 2015, the Australian regulatory body Food Standards Australia New Zealand (FSANZ) denied that nanoparticles were present in Australian food. However, and despite repeated claims from Australia’s food regulator, research commissioned by civil society group Friends of the Earth has demonstrated that nanoparticles are deliberately included as ingredients in an array of food available for sale in Australia. This paper critically examines how nanoparticles have come to be integrated into Australia’s food system under the radar of Australia’s food regulator. Our case study of FSANZ—including its responses to the civil society-led science that determined the existence of nanoparticles in Australian food—raises a number of important questions about the governance of risk in relation to emerging technologies such as nanotechnology. In this paper, we argue that FSANZ’ response to the presence of nanotechnology in Australia’s food system is an example of ‘governing with ignorance’. This is demonstrated via the denial and dismissal of science claims as a basis for limited regulatory intervention. FSANZ’ response intersects with the centrality of commercial interests in shaping science research and commercialisation, alongside the ‘hands off’ approach to regulation that is characteristic of neoliberal governance approaches. We conclude by arguing that in the current food governance framework, and alongside a paucity of impact science, civil society plays a vital role in attempts to democratise the Australian food system. © 2017, Springer Science+Business Media B.V., part of Springer Nature.

- Description: This paper investigates events in which cyclists perceive a cycling crash is narrowly avoided (henceforth, a near miss). A cohort of 2038 adult transport and recreational cyclists from New South Wales (Australia) provided self-reported prospectively collected data from cycling diaries to allow the calculation of an exposure-based rate of near misses and investigation of near miss circumstances. During 25,971 days of cycling, 3437 near misses were reported. For a given time cycling, cyclists who rode mainly for transport (compared with those who rode mainly for recreation), and cyclists with less experience (compared to those with more experience) were more likely to report a near miss; older cyclists (60+ years) were less likely to report a near miss than younger cyclists (25-59 years). Where type of near miss was recorded, 72.0% involved motor vehicles, 10.9% involved pedestrians and 6.9% involved other cyclists. Results indicate some similarities between near misses and crashes reported by this cohort during the same reporting period. A bias toward reporting near misses with motor Vehicles was suggested, which likely reflects cyclists' perceptions that crashes involving motor vehicles are particularly serious, and highlights their impact on perceived safety. Given the relative rarity of crashes, and the limited breadth and depth of administrative data, collection of near miss data may contribute to our understanding of cycling safety by increasing the volume and detail of information available for analysis. Addressing the causes of near misses may offer an opportunity to improve both perceived and actual safety for cyclists. (C) 2017 Elsevier Ltd. All rights reserved.

- Description: Cricket was the first sport to publish recommended methods for injury surveillance in 2005. Since then, there have been changes to the nature of both cricket and injury surveillance. Researchers representing the major cricket playing nations met to propose changes to the previous recommendations, with an agreed voting block of 14. It was decided that 10 of 14 votes (70%) were required to add a new definition element and 11 of 14 (80%) were required to amend a previous definition. In addition to the previously agreed 'Match time-loss' injury, definitions of 'General time-loss', 'Medical presentation', 'Player-reported' and 'Imaging-abnormality' injuries are now provided. Further, new injury incidence units of match injuries per 1000 player days, and annual injuries per 100 players per year are recommended. There was a shift towards recommending a greater number of possible definitions, due to differing contexts and foci of cricket research (eg, professional vs amateur; injury surveillance systems vs specific injury category studies). It is recommended that researchers use and report as many of the definitions as possible to assist both comparisons between studies within cricket and with those from other sports.

- Description: Background Very limited research has been undertaken on sex workers' personal romantic relationships and the impact the nature of their work has on their relationships. This exploratory study aimed to explore the impact sex work has on women's personal romantic relationships and the use of mental separation as a coping mechanism to balance the two aspects of their lives. Fifty-five women working in the indoor sex industry in Melbourne, Australia, were recruited to complete a self-report questionnaire about various aspects of their work, including the impact of sex work on their personal relationships. Questionnaires were completed anonymously and included both closed and open-ended questions. A further six women were interviewed to 'member check' the accuracy of the questionnaire findings. Most women (78%) reported that, overall, sex work affected their personal romantic relationships in predominantly negative ways, mainly relating to issues stemming from lying, trust, guilt and jealousy. A small number of women reported positive impacts from sex work including improved sexual self-esteem and confidence. Just under half of women were in a relationship at the time of the study and, of these, 51% reported their partner was aware of the nature of their work. Seventy-seven percent of single women chose to remain single due to the nature of their work. Many women used mental separation as a coping mechanism to manage the tensions between sex work and their personal relationships. Member checking validated the accuracy of the questionnaire data. This exploratory study identified a number of ways in which sex work impacts negatively on women's personal romantic relationships. The findings of this study support the need for further studies to be undertaken to determine if the findings are reflected in a larger, more representative sample of Australian sex workers and should be considered in the context of any future intervention and support programs aimed at addressing the tensions sex workers experience between their work and personal relationships. Greater public awareness and education programs aimed at addressing the negative stigma associated with the sex industry may go some way towards easing the issues faced by women in their personal relationships.

Our review has two main purposes. First, estimate the prevalence of postpartum depressive symptoms in Chinese immigrant women, and then determine risk factors for postpartum depressive symptoms among these women. Methods: The following databases: MEDLINE, Embase, Scopus, Web of Science, PsycINFO and PubMed were used in literature search from their commencements until November 21st 2017. The Joanna Briggs Institute (JBI) Critical Appraisal instruments were used to evaluate the quality of the article. Four studies met the inclusion criteria, contributed to our review and meta-analysis. Result: The prevalence of postpartum depression is high in Chinese immigrant women. Risk factors for postpartum depression in Chinese immigrant women were defined as lack of social support, unstable economic status, and acculturation. Conclusion: There have been few studies on postpartum depression among Chinese immigrant women. Existing studies have shown a high prevalence of postpartum depression in Chinese immigrant women. Moreover, there is an urgent need for studies on postpartum depression among Chinese immigrant women informing better understanding, programs of care and improving the perinatal health status of Chinese immigrant women.

- Description: It is estimated that as of 2017 around 120 nations around the globe had legislation to protect personal data with at least another 30 in train. Many of the early regimes (dating back to the 1980s and 90s) reflect the OECD Guidelines on the Protection of Privacy and Transborder Flows of Personal Data (1980, updated 2013). However, there are also increasing concerns that these guidelines may no longer be fit for purpose with recent issues regarding breaches of data security and privacy. The EU's General Data Protection Regulation (GDPR) (2016) implements a reformed data privacy regime. Tellingly, some of the new and pending privacy regulations elsewhere reflect the GDPR, a characteristic that suggests much about the impact of international trade. Two questions arise: first, how is the GDPR likely to affect and influence governance of organisations, not only those domiciled in the EU, but also those trading with the Union or having a presence there? Second, compared to the GDPR, what gaps are there in other existing privacy regimes and what are the implications for the governance of those organisations and their risk management strategies? This paper compares the GDPR with privacy regimes in place in New Zealand and Australia (the first of which has GDPR “approved country status” for receipt of data) and attempts to answer the questions above, thus providing a focus for empirical research. As such, the paper provides insight into the impact of the data privacy and security legislative reform, on corporate governance, strategy and risk management beyond the EU in its reach to far distant regions. © The Authors, 2018.

- Description: Patellar tendinopathy (PT) is a leading cause of morbidity in jump-landing athletes. Landing mechanics are identified as a factor associated with PT and/or patellar tendon abnormality. This study aimed to identify key jump-landing variables associated with PT. Thirty-six junior elite basketball players (men n = 18, women n = 18) were recruited from a Basketball Australia development camp. Three-dimensional (3D) kinematic and ground reaction force (GRF) data during a stop-jump task were collected as well as ultrasound scans of the patellar tendons and recall history of training load data. Mixed-model factorial analyses of variance were used to determine any significant between-group differences. Of the 23 participants included for statistical analyses, 11 had normal bilateral patellar tendons (controls) and eight reported PT (currently symptomatic); however, the four participants categorized as asymptomatic with patellar tendon abnormality on diagnostic imaging were excluded from statistical analyses due to their small sample size. Athletes with PT displayed a similar knee flexion angle at initial foot-ground contact (IC) and hip extension strategy during a stop-jump horizontal landing. Despite a similar kinematic technique, athletes with PT utilized a strategy of a longer stance duration phase from IC to peak force. This strategy did not lead to those athletes with PT decreasing their peak vertical GRF nor patellar tendon force during landing but enabled these athletes to land with a lower rate of loading (control 59.2 +/- 39.3 vs. PT 29.4 +/- 33.7 BW.s-1). Athletes with PT still reported significantly reduced training volume (control 4.9 +/- 1.8 vs PT 1.8 +/- 1.1 sessions/wk; total training time/wk control 2.4 +/- 1.0 vs PT 1.4 +/- 1.1 h/wk).

- Description: Drowning risk factors may be identified by comparing drowning incidence rates for comparable at-risk populations but precise methods are lacking. To address this knowledge gap, an ecological study extrapolated crude time-duration exposure to water for a specified at-risk sample of surf bathers to estimate the bather population for all wave-dominated beaches in Victoria, Australia, over a four-year summer season period. An incidence rate was calculated using surf bather drowning deaths frequencies matched for time and location. For the sample, 47,341 hours of surf bathing were estimated from 177,528 bathing episodes. Generalising these results to Victoria, the crude drowning deaths incidence rate in the summer season was 0.41 per 1,000,000 person-hours of surf bathing (95% CI 0.37–0.45). Further application of the method, particularly in open water settings, may be used to identify candidate drowning risk factors to advance drowning prevention strategies.

- Description: ObjectiveLevels of suicidal behavior among gay men are a significant concern. The Interpersonal Theory of Suicide proposes that being unpartnered is a risk factor for suicidal behavior due to thwarted belongingness; however, this has yet to be tested empirically. Recent studies also indicate that the two components of hope, agency and pathways, may be protective against suicidal behavior. The first aim of the current study was to investigate whether thwarted belongingness mediates the relationship between relationship status and suicidal behavior in gay men. The study also examined whether agency and pathways weaken the association between relationship status and thwarted belongingness, and whether agency weakens the relation between thwarted belongingness and suicidal behavior. MethodA sample of 370 self-identified gay men aged from 18 to 66 years old (M = 26.13, SD = 8.02) completed the Suicidal Behaviors Questionnaire-Revised, the Interpersonal Needs Questionnaire-Revised, and the Adult Dispositional Hope Scale.

- Description: In Australia, international students have not only made an enormous economic contribution to the educational sector, but also enriched the cultural diversity of Australian institutions and societies. When international students become a part of the Australian community, issues related to their personal safety are significant, not only to relevant authorities but also to the broader community. This study aimed to investigate the safety of international students at a regional campus and surrounding environment. Semi-structured interviews were conducted with 25 international students aimed at exploring the current concerns and needs regarding their safety on and off campus. In addition, a focus group discussion was conducted with five stakeholders to investigate ways to improve the safety of international students in the current context. Four main themes emerged from the data, including safety concerns, safety risks, preventative safety strategies, and safety needs. One of the most frequent suggestions was to increase the reach of surveillance, greater support from the responsible authorities, particularly as related to environments beyond the confines of the university campus. The findings of this study have offered practical implications associated with the enhancement of the safety of international students in regional Australia.
