The effect of therapeutic and deterrent messages on Internet users attempting to access ‘barely legal’ pornography
No full textOnline child sexual abuse material (CSAM) is a growing problem. Prevention charities, such as Stop It Now! UK, use online messaging to dissuade users from viewing CSAM and to encourage them to consider anonymous therapeutic interventions. This experiment used a honeypot website that purported to contain barely legal pornography, which we treated as a proxy for CSAM. We examined whether warnings would dissuade males (18–30 years) from visiting the website. Participants (n = 474) who attempted to access the site were randomly allocated to one of four conditions. The control group went straight to the landing page (control; n = 100). The experimental groups encountered different warning messages: deterrence-themed with an image (D3; n = 117); therapeutic-themed (T1; n = 120); and therapeutic-themed with an image (T3; n = 137). We measured the click through to the site. Three quarters of the control group attempted to enter the pornography site, compared with 35 % to 47 % of the experimental groups. All messages were effective: D3 (odds ratio [OR] = 5.02), T1 (OR = 4.06) and T2 (OR = 3.05). Images did not enhance warning effectiveness. We argue that therapeutic and deterrent warnings are useful for CSAM-prevention
Unravelling large-scale patterns and drivers of biodiversity in dry rivers
No full textMore than half of the world’s rivers dry up periodically, but our understanding of the biological communities in dry riverbeds remains limited. Specifically, the roles of dispersal, environmental filtering and biotic interactions in driving biodiversity in dry rivers are poorly understood. Here, we conduct a large-scale coordinated survey of patterns and drivers of biodiversity in dry riverbeds. We focus on eight major taxa, including microorganisms, invertebrates and plants: Algae, Archaea, Bacteria, Fungi, Protozoa, Arthropods, Nematodes and Streptophyta. We use environmental DNA metabarcoding to assess biodiversity in dry sediments collected over a 1-year period from 84 non-perennial rivers across 19 countries on four continents. Both direct factors, such as nutrient and carbon availability, and indirect factors such as climate influence the local biodiversity of most taxa. Limited resource availability and prolonged dry phases favor oligotrophic microbial taxa. Co-variation among taxa, particularly Bacteria, Fungi, Algae and Protozoa, explain more spatial variation in community composition than dispersal or environmental gradients. This finding suggests that biotic interactions or unmeasured ecological and evolutionary factors may strongly influence communities during dry phases, altering biodiversity responses to global changes
Exploring the effects of a graduate level trauma-informed care education program for child welfare professionals
No full textThe national child welfare agency in Ireland identified the integration of trauma-informed practices as a service need, in the current significantly challenging practice climate. A promising program that meets the need of child welfare professionals to support need has been developed and is reported on in this paper. This study aimed to evaluate the effects of a newly developed post-graduate level trauma-informed care program for professionals in the national child welfare agency in Ireland. Study participants were 41 child welfare professionals that included front-line practitioners, supervisors, and senior managers. A pretest–posttest study design was used, data was collected over three-time points to measure the effects of the program on pre-defined outcomes of Trauma-informed Knowledge, Professional Self-efficacy, Professional Quality of Life, and Intention to Leave. Statistically significant positives effects were found in trauma-informed knowledge, professional confidence, burn-out and compassion fatigue/secondary traumatic stress, with effect sizes ranging from medium-large to large (η2=.133toη2=.721) across the intervention time period. The positive impacts arising from the program were sustained for 3 months post-intervention. The results of this initial evaluation are promising in supporting child welfare professionals’ capacity to integrate trauma-informed practices and addressing the need for trauma informed practitioners. The need for further research is highlighted
No- and low-alcohol beer and the sponsorship of sport in Australia: An audit of sponsorship partnerships and analysis of marketing tactics
No full textIntroduction: Alcohol sponsorship of sport is associated with increased alcohol consumption. Little research to date has examined the sponsorship of sport by no- and low-alcohol (NoLo) beverage brands, despite concern that the marketing of these products might be harmful to young people. This study had dual aims: to identify sporting partnerships between NoLo beers and Australian sport, and examine marketing tactics used in social media advertising to promote these partnerships. Methods: Our sample included NoLo beers sold online from three large Australian alcohol retailers. First, we performed a qualitative content analysis of partnerships between NoLo beers and sport using publicly available online information. We then analysed the 118 social media posts of NoLo brands linked to these partnerships using a coding framework adapted from the alcohol literature. Results: Of 34 brands, 13 had sporting sponsorship partnerships across a range of spectator and participatory sports. Key marketing tactics identified on social media were activations, time-and event-specific drinking, influencer marketing, competitions, and corporate social responsibility. In particular, NoLo brands aim to disrupt the sports drink market by advertising their products as healthy recovery drinks, or ‘sports beers’, through activation events. Brands are also using influencer marketing and competitions, two tactics shown to be particularly persuasive for young people. Discussion and Conclusions: NoLo beer brands strategically align with Australian sports to promote NoLo consumption. As they are classified as soft drinks in Australia, NoLo beverages are not regulated like alcohol. Future discussions around sports sponsorship and advertising regulation must consider NoLo products
“I’m still in the lap of the gods… I don’t know whether I’m going to improve or not”: listening to people with dementia or cognitive impairment and their support people, talking about inpatient rehabilitation experiences
No full textAbstract:-Purpose:People with dementia often experience poor outcomes in hospital and prolonged lengths of stay. They are sometimes labelled as having “poor rehabilitation potential”. This study aimed to understand the inpatient rehabilitation experiences of people with dementia or cognitive impairment, and their support people, to inform future work to improve rehabilitation access and outcomes.Materials and methods:An exploratory qualitative study from an interpretivist perspective. Participants were inpatients of a geriatric rehabilitation unit in Australia, and their chosen support people. Semi-structured interviews were audio-recorded and transcribed. An analytical framework was developed and indexed to the dataset, followed by charting and thematic analysis.Results:Ten people with dementia or cognitive impairment and nine support people participated (n = 19). Four themes were identified representing an interpretation of the analysis intended to inform clinical practice: Support patients to engage in the rehabilitation process; create a hospitable environment; recognise and work with care partners; and ensure staff have adequate dementia knowledge.Conclusions:Practical, emotional, process-related, and dementia-specific factors may influence the experiences of people living with dementia or cognitive impairment when participating in inpatient rehabilitation. Future research could investigate whether improvements focused on these factors might enhance quality of care for people with dementia.</p

Evaluation of LAMP for Fasciola hepatica detection from faecal samples of experimentally and naturally infected cattle
No full textFasciola hepatica causes liver fluke disease in production animals and humans worldwide. Faecal egg counts (FEC) are the most common diagnostic tool for the diagnosis of liver fluke disease. However, FEC has low sensitivity and is often unreliable for the detection of patent infection. In this study, loop-mediated isothermal amplification (LAMP) was optimised and evaluated for the detection of Fasciola hepatica infection, with the aim of increased sensitivity and making it suitable for on-farm application. LAMP was initially conducted under laboratory conditions, optimised to enable visual detection using calcein dye. DNA extraction based on bead-beating was developed to enable on-farm application. LAMP results were compared to FEC and polymerase chain reaction (PCR). Under laboratory conditions, LAMP was conducted using two incubation methods: a conventional PCR thermocycler and a field-deployable LAMP instrument. When compared to a ‘rigorous’ FEC protocol consisting of multiple counts using a comparatively large volume of faeces and with infection confirmed post-mortem, LAMP was highly sensitive and specific (using silica membrane DNA extraction sensitivity 88 %, specificity 100 %; using sieving and beat-beating DNA extraction sensitivity 98.9 %, specificity 100 %). When applied on-farm, LAMP was compared to conventional FEC, which suggested high sensitivity but low specificity (sensitivity 97 %, specificity 37.5 %). However, further analysis, comparing field LAMP results to laboratory PCR, suggested that the low specificity was likely the outcome of the inability of conventional FEC to detect all true F. hepatica positive samples. Based on the high sensitivity and specificity of LAMP compared to a ‘rigorous’ FEC protocol and its ability to be used in field settings, the study demonstrates the potential of LAMP for diagnosing F. hepatica infection in agriculture.</p
Engineering Hyperechogenic Colloids with Clot-Targeting Capabilities from Platelet-Derived Membranes
No full textThrombosis-related cardiovascular diseases remain the leading global cause of mortality and morbidity. In this study, we present a pioneering approach in the field of nanobiotechnology, with a focus on clinical translation, aimed at advancing early diagnosis and enhancing treatment options for thrombotic disorders. We introduce the fabrication of Platelet Membrane-Derived Bubbles (PMBs), which exhibit distinctive characteristics compared to conventional nanoparticles. These PMBs possess an average diameter of 700 nm and a negative ζ-potential, mirroring the attributes of parent platelet membranes. Utilizing diagnostic ultrasound imaging, we demonstrated the ability to visualize PMBs as hyperechogenic entities in agarose phantoms in vitro and in live mice in vivo. Furthermore, through confocal laser microscopy, we verified the retention of crucial transmembrane proteins, such as CD41 (GPIIb) and CD42 (GPIb), pivotal in conferring platelet-specific targeting functions. Importantly, our platelet aggregation studies confirmed that PMBs do not induce platelet aggregation but instead adhere to preformed platelet-rich in vitro thrombi. Overall, our work showcases the safe and precise utilization of PMBs to directly target acute thrombosis induced by laser injury in murine mesenteric veins in vivo, as visualized through intravital microscopy. In conclusion, we have successfully developed a rapid method for generating PMBs with unique ultrasound-directed and thrombus-targeting properties. These exceptional attributes of PMBs hold significant promise for advancing the field of ultrasound diagnostic thrombus imaging and clot-targeted therapy in the clinical context.</p
Unravelling the wellbeing needs of Australian teachers: a qualitative inquiry
No full textThe declining wellbeing of Australian teachers is a longstanding problem, with much attention on retention, stress, burnout, and poor resourcing and conditions that impact wellbeing. Additionally, the COVID-19 pandemic has further illuminated these challenges. This qualitative study aimed to explore Australian teachers’ perceptions of their wellbeing needs with a focus on asking the questions that are often not asked—what is working, what are we learning, and how can we move forward to support teacher wellbeing? The voices of teachers revealed findings that support a much-needed shift in teacher wellbeing rhetoric in Australia. We illuminate five key areas that influence teacher and sector perceptions of wellbeing: (1) school leadership, (2) professional development, (3) workload and work-life balance, (4) relationships, and (5) stress, positive emotions, and accomplishment. These findings contribute to the need for a change in how teacher wellbeing is approached and highlight the possible implications of what is working, needs, barriers, and insights for preservice teacher education and professional development of teachers
Insights into a collective impact partnership to promote consumption of healthy drinks in North East Melbourne: A qualitative case study
No full textIssue Addressed: To explore insights and perspectives of a collective impact (CI) partnership taking on a new project that aimed to reduce sugary drink consumption and promote water as the drink of choice across North East Melbourne. Methods: A qualitative case study was undertaken. Semi-structured interviews were conducted with key stakeholders in the partnership. Data were analysed using thematic analysis. Results: Fourteen organisations participated in the North East Healthy Drinks Alliance. The data demonstrated that investing in developing a common agenda supported the establishment of a CI approach. The backbone organisation was found to have played a crucial role in coordinating the activities of the Alliance. This coordination was found to be particularly important in terms of ensuring that organisations were able to work on mutually reinforcing activities at their own pace. Program planning and reporting was managed through open continuous communication by the backbone organisation. The data collected pertains to the activities of the Alliance in its first 2 years, prior to the development of a shared measurement strategy, thus no data was collected on this aspect of the collective impact framework. Although some participants were found to have limited knowledge of CI, this did not seem to hinder their participation in the Alliance. Conclusion: Selecting a relevant and accessible focus area and investing in developing a common agenda supported the establishment of a CI approach. </p
