Restoring South African subtropical succulent thicket using Portulacaria afra: root growth of cuttings differs depending on the harvest site during a drought.

The restoration of succulent thicket (the semi-arid components of the Albany Subtropical Thicket biome endemic to South Africa) has largely focused on the reintroduction of Portulacaria afra L. Jacq-a leaf- and stem-succulent shrub-through the planting of unrooted cuttings directly into field sites. However, there has been inconsistent establishment and survival rates, with low rates potentially due to a range of factors (e.g., post-planting drought, frost or herbivory), including the poor condition of source material used. Here we test the effect of parent-plant and harvesting site on the root development of P. afra cuttings in a common garden experiment. Ten sites were selected along a ∼110 km transect, with cuttings harvested from five parent-plants per site. Leaf moisture content was determined for each parent-plant at the time of harvesting as a proxy for plant condition. Root development-percentage of rooted cuttings and mean root dry weight-was recorded for a subset of cuttings from each parent-plant after 35, 42, 48, 56, and 103 days after planting in a common garden setting. We found evidence for cutting root development (rooting percentage and root dry mass) to be strongly associated with harvesting site across all sampling days (p < 0.005 for all tests). These differences are likely a consequence of underlying physiological factors; this was supported by the significant but weak correlation (r 2 = 0.10-0.26) between the leaf moisture content of the parent-plant (at the time of harvesting) and dry root mass of the cuttings (at each of the sampling days). Our findings demonstrate that varying plant condition across sites can significantly influence root development during dry phases (i.e., intra- and inter-annual droughts) and that this may be a critical component that needs to be understood as part of any restoration programme. Further work is required to identify the environmental conditions that promote or impede root development in P. afra cuttings.

Teen Dating Violence Victimization: Associations Among Peer Justification, Attitudes Toward Gender Inequality, Sexual Activity, and Peer Victimization.

The current study, grounded in a social learning theoretical framework, examined attitudes and behaviors associated with verbal and physical teen dating violence (TDV) victimization. Because TDV varies by gender in both frequency and severity, these associations were examined first within the overall sample, and then by gender to further investigate these differences. A total of 1,884 adolescents (49.2% boys; 50.8% girls; average age 14.79 years; SD = .58) who reported ever dating someone were included in the analysis. Specifically, peers' justification of TDV, attitudes supporting gender inequality, sexual activity, and peer victimization were included to determine their cross-sectional association with verbal and physical TDV victimization. Data were analyzed separately for boys and girls. Results indicated that peers' justification of TDV, peer victimization, sexual activity, and attitudes supporting gender inequality were each associated with higher physical and verbal TDV victimization for girls and boys. Most of these factors remained significant when separated by gender, except for sexual activity and attitudes supporting gender inequality, which were not associated with physical TDV victimization for boys and girls, respectively. Implications for practice and research are discussed.

The injury workforce in Western Australia: Findings from a cross-sectional survey.

ISSUE ADDRESSED: Since 1986, injury prevention and control has been classified as a National Health Priority. However, no reviews into the injury prevention workforce have been conducted in Australia since 2011 and to date; none has focused specifically on the injury prevention and safety promotion sector in Western Australia (WA). This research sought to review the scope of the injury prevention and safety promotion workforce in WA to gain a greater understanding of sector characteristics, work and needs. METHODS: An online, cross-sectional survey was conducted between mid-January and mid-March 2018. Participants were required to be: (a) based in WA or have a program running within WA; and (b) working in injury prevention and safety promotion relating to programs, policy or legislation development, implementation and/or evaluation within intentional (eg interpersonal violence, suicide and self-harm) or unintentional injuries (eg transport, poisoning, falls, drowning, burns) or farm, child and community, occupational health and safety, sport and recreation and trauma. RESULTS: The research found that participants were predominantly female (82%), aged 40 years or older (66.1%) and were employed full time (55.6%). The majority of participants worked in falls prevention (38.5%), alcohol and other drugs (38.0%), injury in general (31.8%) and community safety (30.7%). CONCLUSIONS: Findings demonstrate significant heterogeneity with a core workforce supported by a range of non-core and indirect actors. Identifying characteristics and needs of the workforce supports coordinated capacity building to implement effective injury prevention and safety promotion initiatives. With this being the first review of the workforce in WA, this article highlights the need to more regularly audit the sector to determine its breadth and composition. SO WHAT?: In the light of the recent announcement by the Commonwealth for a new national Injury Prevention Strategy, this study provides timely insights into the injury prevention and safety promotion sector in WA.

What's wrong with John? a randomised controlled trial of Mental Health First Aid (MHFA) training with nursing students.

BACKGROUND: The prevalence of mental health problems have been found to be higher among university students compared to their non-student peers. Nursing students in particular face a range of additional stressors which may impact their undergraduate performance and their careers. Mental Health First Aid (MHFA) aims to increase mental health literacy and to reduce stigma and may positively impact on the student population. This paper describes a MHFA randomised controlled trial targeting nursing students at a large Australian university. This study aimed to measure the impact of the MHFA course on mental health literacy, mental health first aid intentions, confidence in helping someone with a mental health problem and stigmatising attitudes including social distance. METHODS: Participants were first year nursing students (n = 181) randomly allocated to the intervention (n = 92) or control (n = 89) group. Intervention group participants received the standardised MHFA course for nursing students. Online self-report questionnaires were completed at three time intervals: baseline (one week prior to the intervention: T1) (n = 140), post intervention (T2) (n = 120), and two months post intervention (T3) (n = 109). Measures included demographics, mental health knowledge, recognition of depression, confidence in helping, mental health first aid intentions and stigmatising attitudes including social distance. Repeated measures ANOVA was computed to measure if the impact of time (T1, T2, T3) and group (intervention and control) on the outcome variables. RESULTS: There was a significant improvement among intervention compared to control group participants across the three time periods for knowledge scores (p < 0.001), confidence in helping (p < 0.001), mental health first aid intentions (p < 0.001), total personal stigma (p < 0.05), personal dangerous/unpredictable stigma (p < 0.05) and social distance (p < 0.05) scores. CONCLUSION: MHFA is useful training to embed in university courses and has the potential to enhance mental health literacy and reduce stigmatising attitudes and social distance. While this course has particular salience for nursing and other health science students, there are broader benefits to the general university population that should be considered and opportunities accordingly explored for all students to complete the course.

Mental health first aid training for nursing students: a protocol for a pragmatic randomised controlled trial in a large university.

BACKGROUND: The impact of mental health problems and disorders in Australia is significant. Mental health problems often start early and disproportionately affect young people. Poor adolescent mental health can predict educational achievement at school and educational and occupational attainment in adulthood. Many young people attend higher education and have been found to experience a range of mental health issues. The university setting therefore presents a unique opportunity to trial interventions to reduce the burden of mental health problems. Mental Health First Aid (MHFA) aims to train participants to recognise symptoms of mental health problems and assist an individual who may be experiencing a mental health crisis. Training nursing students in MHFA may increase mental health literacy and decrease stigma in the student population. This paper presents a protocol for a trial to examine the efficacy of the MHFA training for students studying nursing at a large university in Perth, Western Australia. METHODS/DESIGN: This randomised controlled trial will follow the CONSORT guidelines. Participants will be randomly allocated to the intervention group (receiving a MHFA training course comprising two face to face 6.5 hour sessions run over two days during the intervention period) or a waitlisted control group (not receiving MHFA training during the study). The source population will be undergraduate nursing students at a large university located in Perth, Western Australia. Efficacy of the MHFA training will be assessed by following the intention-to-treat principle and repeated measures analysis. DISCUSSION: Given the known burden of mental health disorders among student populations, it is important universities consider effective strategies to address mental health issues. Providing MHFA training to students offers the advantage of increasing mental health literacy, among the student population. Further, students trained in MHFA are likely to utilise these skills in the broader community, when they graduate to the workforce. It is anticipated that this trial will demonstrate the scalability of MHFA in the university environment for pre-service nurses and that implementation of MHFA courses, with comprehensive evaluation, could yield positive improvements in the mental health literacy amongst this target group as well as other tertiary student groups.

Recreational Drowning Prevention Interventions for Adults, 1990-2012: A Review.

Drowning is a frequently occurring and preventable public health issue. Internationally, drowning literature has focussed on children under 5 years, however, evidence based interventions to prevent adult drowning are needed to reduce deaths on a global scale. The aim of this paper is to systematically identify and analyse the evidence for drowning interventions with an adult focus. A systematic search was undertaken for peer-reviewed articles which were published in English between 1990 and 2012, focused on adults and described a drowning intervention. After quality appraisal by expert reviewers using a purposively tailored checklist, a final total of six studies were included for review. The six studies were all conducted in high income countries. Four were drowning interventions, two were retrospective analyses. The drowning interventions duration ranged from 10 days to 5 years, the analysis studies from 6 to 21 years. Two of the studies reviewed used behaviour change theory to inform development, and two reported formative evaluation. Prevention strategies included education (n = 3), technology (n = 1) and environmental (n = 1). Positive short term effects and significant behaviour change in life jacket use was reported (n = 2). A mixed effect was observed in the six studies. The complexity of the issues surrounding drowning requires the collection of robust data and evaluation of preventative measures to support the development of targeted and tailored prevention interventions. This review reinforces the need for a genuine and sustained global approach to addressing adult drowning prevention. Drowning is a serious public health issue and should receive the same attention as other public health priorities .
