Law enforcement is inherently stressful, and police officers are particularly vulnerable to mental and physical disorders. As such, researchers are currently assessing intervention strategies that may combat or manage these psychological, physical and mental issues. To review most recent information regarding anxiety, PTSD, and sleepiness and fatigue and identify the interventions and treatments proposed to overcome work related stressors and associated mental illnesses inflicting law enforcement officers. The EMBASE, OVID MEDLINE and PsycINFO databases were canvassed for articles investigating anxiety, post-traumatic stress disorder, sleepiness, and fatigue. Initial article selections were made based on title, whilst final inclusion was informed by a full critical appraisal with respect to the primary and secondary effects. The systematic search returned 363 records, of which 183 were unique. Following screening, 43 records were included in the final review. The included literature assessed the efficacy of several interventions, and provided a number of recommendations regarding interventions, and policy. Moreover, literature indicates that police officers benefit from interventions targeting work-related stress and potential psychological disorders, if these interventions are continuous. Furthermore, larger controlled studies are required to further elucidate the benefits of psychosocial intervention in law enforcement.

© 2018 World Stroke Organization. Background: Limited evidence exists to support very early intensive aphasia rehabilitation after stroke. VERSE is a PROBE trial designed to determine whether two types of intensive aphasia therapy, beginning within 14 days of acute stroke, provide greater therapeutic and cost-effectiveness than usual care. Objective: To publish the detailed statistical analysis plan for the VERSE trial prior to unblinding. This statistical analysis plan was based on the published and registered VERSE trial protocol and was developed by the blinded steering committee and management team, led by the trial statistician. This plan was developed using outcome measures and trial data collection forms. Results: The VERSE statistical analysis plan is consistent with reporting standards for clinical trials and provides for clear and open reporting. Conclusions: Publication of a statistical analysis plan serves to reduce potential trial reporting bias and outlines transparent pre-specified analyses. Australian New Zealand Clinical Trials Registry (ANZCTR) Registration number: ACTRN12613000776707; Universal Trial Number (UTN) is U1111-1145-4130.

The choice of technologies used to remediate contaminated environments are increasingly made via engagement with affected local residents. Despite this, little is known about how residents perceive remediation technology applications. Building on the findings of broader technology worry research, and drawing on data from a telephone survey of 2009 residents living near thirteen contaminated sites in Australia, regression analysis of closed-ended survey questions and coding analysis of open-ended survey questions are combined to identify the main predictors of worries concerning particular remediation technologies, and how worry affects them. This suggests respondents are more worried about the application of chemical remediation technologies than the application of physical and thermal technologies, which in turn caused more worry than the application of biotechnology. The paper suggests that these worries can be reduced via direct engagement with residents about remediation technologies, suggesting that such engagement can provide knowledge that improves remediation technology decisions.

In recent decades the diversity of remediation technologies has increased significantly, with the breadth of technologies ranging from dig and dump to emergent technologies like phytoremediation and nanoremediation. The benefits of these technologies to the environment and human health are believed to be substantial. However, they also potentially constitute risks. Whilst there is a growing body of knowledge about the risks and benefits of these technologies from the perspective of experts, little is known about how residents perceive the risks and benefits of the application of these technologies to address contaminants in their local environment. This absence of knowledge poses a challenge to remediation practitioners and policy makers who are increasingly seeking to engage these affected local residents in choosing technology applications. Building on broader research into the perceived benefits and risks of technologies, and data from a telephone survey of 2009 residents living near 13 contaminated sites in Australia, regression analysis of closed-ended survey questions and coding of open-ended questions are combined to identify the main predictors of resident's perceived levels of risk and benefit to resident's health and to their local environment from remediation technologies. This research identifies a range of factors associated with the residents' physical context, their engagement with institutions during remediation processes, and the technologies which are associated with residents' level of perceived risk and benefit for human health and the local environment. The analysis found that bioremediation technologies were perceived as less risky and more beneficial than chemical, thermal and physical technologies. The paper also supports broader technology research that reports an inverse correlation between levels of perceived risks and benefits. In addition, the paper reveals the types of risks and benefits to human health and the local environment that...

Rationale: The efficacy of rehabilitation therapy for aphasia caused by stroke is uncertain.
Aims and hypothesis: The Very Early Rehabilitation of Speech (VERSE) trial aims to determine if intensive prescribed aphasia therapy (VERSE) is more effective and cost saving than non-prescribed, intensive (usual care-plus) and non-intensive usual care (UC) therapy when started within 15 days of stroke onset and continued daily over four weeks. We hypothesize that aphasia therapy when started very early after stroke and delivered daily could enhance recovery of communication compared with UC.
Sample size estimates: A total of 246 participants (82 per arm) will provide 80% power to detect a 4.4% improvement on aphasia quotient between VERSE and UC plus at a significance level of =0.05.
Setting: Acute-care hospitals and accompanying rehabilitation services throughout Australia, 2014–2017.
Design: Three-arm, prospective, randomized, parallel group, open-label, blinded endpoint assessment (PROBE) trial.
Participants: Acute stroke in previous 14 days and aphasia diagnosed by aphasia quotient (AQ) of the Western Aphasia Battery (WAB).
Randomization: Computer-generated blocked randomization procedure stratified by aphasia severity according to Western Aphasia Battery, to one of three arms.
Intervention: All participants receive UC—usual ward-based aphasia therapy. Arm 1: UC—no additional therapy; Arm 2: UC-plus usual ward-based therapy; Arm 3: VERSE therapy—a prescribed and structured aphasia therapy program. Arms 2 and 3 receive a total of 20 additional sessions (45–60min, provided daily) of aphasia therapy. The additional intervention must be provided before day 50 post stroke.
Study outcome measures: The aphasia quotient of Western Aphasia Battery at 12 weeks post stroke. Secondary outcomes include discourse measures, the Stroke and Aphasia Quality of Life Scale-39 and the Aphasia Depression Rating Scale at 12 and 26 weeks.
Economic evaluation: Incremental cost-effectiven...
Perrault, KA, Stefanuto, P-H, Stuart, BH, Rai, T, Focant, J-F & Forbes, SL 2015, 'Reducing variation in decomposition odour profiling using comprehensive two-dimensional gas chromatography.', Journal of Separation Science, vol. 38, no. 1, pp. 73-80.View/Download from: UTS OPUS or Publisher's site
Challenges in decomposition odour profiling have led to variation in the documented odour profile by different research groups worldwide. Background subtraction and use of controls are important considerations given the variation introduced by decomposition studies conducted in different geographical environments. The collection of volatile organic compounds (VOCs) from soil beneath decomposing remains is challenging due to the high levels of inherent soil VOCs, further confounded by the use of highly sensitive instrumentation. This study presents a method that provides suitable chromatographic resolution for profiling decomposition odour in soil by comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry using appropriate controls and field blanks. Logarithmic transformation and t-testing of compounds permitted the generation of a compound list of decomposition VOCs in soil. Principal component analysis demonstrated the improved discrimination between experimental and control soil, verifying the value of the data handling method. Data handling procedures have not been well documented in this field and standardisation would thereby reduce misidentification of VOCs present in the surrounding environment as decomposition byproducts. Uniformity of data handling and instrumental procedures will reduce analytical variation, increasing confidence in the future when investigating the effect of taphonomic variables on the decomposition VOC profile.

Cadaver-detection dogs are regularly used by police and emergency services to locate human remains. Because of ethical restrictions, the dogs are not trained using cadavers, but instead, on pseudo-scents or human tissues, such as blood, bone, and decomposition fluid. However, the accuracy of these training aids as substitutes for human remains is unknown. The aim of this study was to investigate the dogs' sensitivity to human decomposition fluid as a training aid and to determine whether their sensitivity increased with exposure.
This study investigated how teachers are using distinctive pedagogical features of mobile learning: collaboration, personalisation and authenticity. The researchers developed and validated a survey instrument based on these three established constructs (Kearney, Schuck, Burden, & Aubusson, 2012) and used it to interrogate current mobile learning practices in school and university education. This paper focuses on data from school teachers (n = 107). Findings indicated that teachers' perceptions of authenticity were high but aspects of online collaboration, networking and student agency were rated surprisingly lower than expected, given the rhetoric about enhanced connection and flexible learning opportunities afforded by mobile technologies. Device ownership was identified as one factor influencing adoption of these mobile pedagogies. Implications for effective use of handheld devices in teaching are addressed.

Very early aphasia rehabilitation studies have shown mixed results. Differences in therapy intensity and therapy type contribute significantly to the equivocal results. This work compares a standardised, prescribed very early aphasia therapy regimen to a historical usual care control group at therapy completion (4-5 weeks post-stroke) and again at follow-up (six months).

Purpose The aims of the current study were to describe the extrinsic and intrinsic factors affecting sleep in critically ill patients and to examine potential relationships with sleep quality. Materials and Methods Sleep was recorded using polysomnography (PSG) and self-reports collected in adult patients in intensive care. Sound and illuminance levels were recorded during sleep recording. Objective sleep quality was quantified using total sleep time divided by the number of sleep periods (PSG sleep period time ratio). A regression model was specified using the PSG sleep period time ratio as a dependent variable. Results Sleep was highly fragmented. Patients rated noise and light as the most sleep disruptive. Continuous equivalent sound levels were 56 dB (A). Median daytime illuminance level was 74 lux, and nighttime levels were 1 lux. The regression model explained 25% of the variance in sleep quality (P = .027); the presence of an artificial airway was the only statistically significant predictor in the model (P = .007). Conclusions The presence of an artificial airway during sleep monitoring was the only significant predictor in the regression model and may suggest that although potentially uncomfortable, an artificial airway may actually promote sleep. This requires further investigation.
This paper considers the risk of disclosure in linked databases when statistical analysis of micro-data is permitted. The risk of dis- closure needs to be balanced against the utility of the linked data. The current work specifically considers the disclosure risks in permit- ting regression analysis to be performed on linked data. A new attack based on partitioning of the database is presented.

Background:â Multimarker quantitative real-time polymerase chain reaction (qRT-PCR) represents an effective method for detecting circulating tumour cells in the peripheral blood of patients with melanoma. Objectives:â To investigate whether the phenotype of circulating melanoma cells represents a useful indicator of disease stage, recurrence and treatment efficacy. Methods:â Peripheral blood was collected from 230 patients with melanoma and 152 healthy controls over a period of 3 years and 9 months. Clinical data and blood samples were collected from patients with primary melanoma (early stages, 0âII, n = 154) and metastatic melanoma (late stages, IIIâIV, n = 76). Each specimen was examined by qRT-PCR analysis for the expression of five markers: MLANA, ABCB5, TGFÎ²2, PAX3d and MCAM. Results:â In total, 212 of the patients with melanoma (92%) expressed markers in their peripheral blood. Two markers, MLANA and ABCB5, had the greatest prognostic value, and were identified as statistically significant among patients who experienced disease recurrence within our study period, being expressed in 45% (MLANA) and 49% (ABCB5) of patients with recurrence (P = 0Â·001 and P = 0Â·031, respectively). For patients administered nonsurgical treatments, MCAM expression correlated with poor treatment outcome. Conclusions:â Circulating tumour cells were detectable at all stages of disease and long after surgical treatment, even when patients were considered disease free. Specifically, expression of ABCB5 and MLANA had significant prognostic value in inferring disease recurrence, while MCAM expression was associated with poor patient outcome after treatment, confirming multimarker qRT-PCR as a potential technique for monitoring disease status.

Background and Aim: The effects of very early aphasia therapy on recovery are equivocal. This article examines predictors of very early aphasia recovery through statistical modeling. Methods: This study involved a secondary analysis of merged data from two randomized, single-blind trials conducted in Australian acute and subacute hospitals. Study 1 (n = 59) compared daily therapy to usual ward care for up to 4 weeks poststroke in patients with moderate to severe aphasia. Study 2 (n = 20) compared daily group therapy to daily individual therapy for 20 1-hour sessions over 5 weeks, in patients with mild to severe aphasia. The primary outcome measure was the Western Aphasia Battery Aphasia Quotient (AQ) at therapy completion. This analysis used regression modeling to examine the effects of age, baseline AQ and baseline modified Rankin Scale (mRS), average therapy amount, therapy intensity, and number of therapy sessions on aphasia recovery. Results: Baseline AQ (p = 0.047), average therapy amount (p = 0.030), and baseline mRS (p = 0.043) were significant predictors in the final regression model, which explained 30% (p < 0.001) of variance in aphasia recovery. Conclusion: The amount of very early aphasia therapy could significantly affect communication outcomes at 4 to 5 weeks poststroke. Further studies should include amount of therapy provided to enhance reliability of prognostic modeling in aphasia recovery.

Objective the ongoing attrition of the midwifery workforce frustrates future workforce planning and the provision of maternity services in Western Australia. This project determined factors contributing to the intention of the midwives to move jobs and/or leave the profession. Design a cross-sectional survey approach was taken for this descriptive research utilising a self-administered questionnaire developed by the Nursing and Midwifery Office, Department of Health, Western Australia. Setting public and private health sectors in Western Australia, AprilMay 2010. Participants 1,600 midwives employed in the public and private health sectors throughout Western Australia were invited to participate: 712 responded (44.5%), one-fifth of the state's registered midwives. Findings most midwives worked part-time in a clinical role in public hospitals. Almost half intended moving jobs within 5 years and/or leaving midwifery. Excluding midwives of retirement age, the most common reasons for intending to move jobs were family commitments, working conditions and role dissatisfaction. Those intending to leave midwifery cited work-life balance, career change and family commitments. Midwives thought addressing the following issues would improve midwifery retention: flexible work arrangements, remuneration, staffing and caseload, workplace culture, professional development and models of care.

Background and purpose Early stroke rehabilitation has shown benefits over spontaneous recovery. Insufficient evidence exists to determine the benefits of early aphasia intervention. We hypothesized that daily aphasia therapy would show better communication outcomes than usual care (UC) in early poststroke recovery. Method This prospective, randomized, single-blinded, controlled trial was conducted in three acute-care hospitals in Perth, Australia, each with over 200 stroke admissions annually. Patients with acute stroke causing moderate to severe aphasia were recruited at a median of three-days (range: 0-10 days) to receive daily aphasia therapy or usual care therapy. Individually tailored, impairment-based intervention was provided for the acute hospital stay or intervention phase (median: 19 days; range: 5-76). Primary outcome measures were the aphasia quotient and functional communication profile at acute hospital discharge or four-weeks poststroke, whichever came first. A random-number generator and sealed envelopes were used to randomize participants. Assessments were completed by a blinded assessor. Results Fifty-nine participants were recruited, with six withdrawals (10%) and seven deaths (12%) at six-months. Ninety percent had ischemic strokes, with 56.5% experiencing a total anterior circulation stroke. The group mean (Â±SD) age was 69.1 (Â±13.9) years. Six participants (18.75%) in the daily aphasia therapy group did not complete the minimum (150 min) therapy required for this study. The daily aphasia therapy intervention phase mean therapy session time was 45 min (range: 30-80) and the total mean amount of therapy for the daily aphasia therapy participants was 331 min (range: 30-1415). Four (15%) participants in the usual care group received therapy. The collective total therapy provided to these participants was 295 min over seven sessions. Usual care participants received an average of 10.5 min of therapy per week during the intervention phase. At th...
