Abstract: This study seeks to assess the health, social and economic outcomes associated with rough sleeping among women and compare those outcomes with those of (1) men sleeping rough, and (2) women experiencing other forms of homelessness (such as being housed in temporary supported accommodation due to family and domestic violence). The paper analyses survey data using the Vulnerability Index-Service Prioritization Decision Analysis Tool (VI-SPDAT) collected from 2735 women experiencing homelessness and 3124 men sleeping rough in Australian cities from 2010 to 2017. We find that women sleeping rough report poorer physical and mental health outcomes and greater problematic drug and or alcohol use relative to both men sleeping rough and women experiencing other types of homelessness (all p < 0.5). Women sleeping rough report significantly higher levels of crisis service utilisation (Β = 17.9, SE = 3.9, p < 0.001) and interactions with police in the previous 6 months (Β = 1.9, SE = 0.3, p < 0.001) than women experiencing homelessness not sleeping rough. Women sleeping rough also report greater healthcare utilisation, and, therefore, healthcare costs, than women experiencing homelessness not sleeping rough and men sleeping rough (all p < 0.05). From a policy perspective, the evidence presented in this paper supports a social determinants approach that moves from addressing symptoms of poor health outcomes associated with homelessness to preventing and ending homelessness with a particular focus on the life trajectories of women. Integrated services and homelessness strategies need to be developed through a gender lens, providing women sleeping rough with tailored permanent housing with wrap-around supportive housing to address poor health outcomes.

Abstract: This study aimed to determine and compare Radiation Therapists' (RTs') and Radiation Oncology Medical Physicists' (ROMPs') perspectives about their profession and workplace, satisfaction with career progression opportunities, and leaving the current workplace. RTs and ROMPs who were currently or had previously worked in Australia were invited to complete an online survey. Univariate and multivariate methods were used for analysis. Participants were 342 RTs and 112 ROMPs with estimated response rates of 14% and 26% respectively. Both professions rated workload poorly and identified the need for improvement in: communication between professions' members, support for junior staff/new graduates, staff morale, on-site training and multidisciplinary communication. RTs, more than ROMPs, perceived their profession was recognised and respected, but RTs were less likely to be satisfied with career progression/advancement, job promotion prospects and opportunities to specialise. At least 20% of RTs and ROMPs were thinking about leaving their workplace and 13% of RTs and 8% of ROMPs were thinking about leaving their profession. Different factors contributed to workforce satisfaction and retention within each profession. Staff satisfaction and career progression are critical to retain RTs and ROMPs. Further research is required to explore strategies to address workplace dissatisfaction, recruitment and retention.

Abstract: Physical activity reduces cardiovascular risk, partly via direct effects on the arterial wall. We hypothesized that vascular function responses would be modality-specific, sex-dependent, and express a high degree of heritability. We recruited 90 same-sex twins (31 monozygotic, 14 dizygotic dizygotic pairs 25.8±6.0 years) and randomized 70 (25 monozygotic, 10 dizygotic) to complete, as pairs, 3 months each of resistance and endurance training, separated by a 3-month washout. Brachial artery flow-mediated (FMD%) and glyceryl-trinitrate induced dilation (GTN%) both increased following endurance (FMD%: ∆1.46%, P .001 GTN%: ∆1.76%, P =0.004) and resistance (FMD%: ∆1.73%, P .001 GTN%: ∆1.68%, P =0.045). About one-third of participants failed to respond to one or other mode 10% failed to respond to both for FMD% (17% for GTN%). FMD% and GTN% increased significantly in response to both resistance and endurance in females ( P .05), but not males. Twin analysis revealed that responses to both FMD% and GTN% with exercise training for both modalities were dependent on factors shared by monozygotic pairs and that a large contribution from genetic effects is unlikely. Our findings indicate that both endurance and resistance can enhance vascular function and that responses in females were more marked. Most in iduals respond to one or other form of training, with few unresponsive to both a finding that has implications for optimizing exercise-based approaches for in idualized benefit. Focusing on characteristics of exercise prescription may be more important than the impact of distinct candidate genes when considering exercise as a form of vascular medicine.

Abstract: There has been a growing interest in computational electroencephalogram (EEG) signal processing in a erse set of domains, such as cortical excitability analysis, event-related synchronization, or desynchronization analysis. In recent years, several inconsistencies were found across different EEG studies, which authors often attributed to methodological differences. However, the assessment of such discrepancies is deeply underexplored. It is currently unknown if methodological differences can fully explain emerging differences and the nature of these differences. This study aims to contrast widely used methodological approaches in EEG processing and compare their effects on the outcome variables. To this end, two publicly available datasets were collected, each having unique traits so as to validate the results in two different EEG territories. The first dataset included signals with event-related potentials (visual stimulation) from 45 subjects. The second dataset included resting state EEG signals from 16 subjects. Five EEG processing steps, involved in the computation of power and phase quantities of EEG frequency bands, were explored in this study: artifact removal choices (with and without artifact removal), EEG signal transformation choices (raw EEG channels, Hjorth transformed channels, and averaged channels across primary motor cortex), filtering algorithms (Butterworth filter and Blackman–Harris window), EEG time window choices (−750 ms to 0 ms and −250 ms to 0 ms), and power spectral density (PSD) estimation algorithms (Welch’s method, Fast Fourier Transform, and Burg’s method). Powers and phases estimated by carrying out variations of these five methods were analyzed statistically for all subjects. The results indicated that the choices in EEG transformation and time-window can strongly affect the PSD quantities in a variety of ways. Additionally, EEG transformation and filter choices can influence phase quantities significantly. These results raise the need for a consistent and standard EEG processing pipeline for computational EEG studies. Consistency of signal processing methods cannot only help produce comparable results and reproducible research, but also pave the way for federated machine learning methods, e.g., where model parameters rather than data are shared.

Abstract: To investigate: (1) whether TV watching habits throughout childhood and adolescence, a proxy of sedentary behaviour, impacted cardiorespiratory fitness (CRF) in adulthood, and (2) whether any potential impact of TV watching in childhood and adolescence on CRF in adulthood was changed by adult physical activity (PA) levels. A longitudinal study with questionnaire data available regarding TV watching collected at ages 5, 8, 10, 14, 17 and 20 yrs, allowed trajectories of TV watching to be developed. At age 28 yrs, participants completed a V̇O
