Internal flow characteristics of radial rotating oscillating heat pipe filled with acetone or water
No full textThe study investigates the internal flow dynamics of radial rotating oscillating heat pipes (RaRo-OHPs) to assess their potential applications in rotations. It examines influences of heat flux and centrifugal acceleration on thermal conditions and internal flow in RaRo-OHPs. Results show that both Bo and Fr rise significantly with increased centrifugal acceleration and heat flux, emphasizing radial rotation's impact on internal flow. With increment of heat flux and centrifugal acceleration, flow pattern analysis reveals shifts from slug/annular flow to churn flow/separation of vapor-liquid phases; motion modes progress from pendulum oscillation to circulation, then oscillation or single/double-side boiling. Visualizations underscore the importance of maintaining vapor slugs and liquid plugs for effective circulation flow and heat transfer. It is noted that under radial rotation, slug flow and the circulation of chains of vapor slugs and liquid plugs were still observed, achieving Bo of 8.26 for acetone and 5.10 for water as the working fluid. Compared with the static state, radial rotation can promote the internal flow, the velocity increases by 228% and 185% for RaRo-OHPs filled with acetone and water, respectively. The study emphasizes the capillary effect's role in enhancing internal flow under radial rotations, crucial for improving thermal performance

Depression, anxiety, and life satisfaction in gay and bisexual men in Lebanon:A cross-sectional correlational study
No full textMinority stress theory postulates that exposure to distal and proximal stressors due to one’s sexual orientation can undermine mental health outcomes and identity process theory posits that mental health is undermined when these stressors result in identity threat (i.e., decreased levels of self-esteem, self-efficacy, continuity and positive distinctiveness). Drawing upon tenets of these theories, this study examines the unique contributions of intrapsychic and group-based factors to predicting depression, anxiety and life satisfaction in a sample of 241 gay and bisexual men in Lebanon. Cross-sectional correlational survey data were analyzed using hierarchical multiple regression. Life satisfaction was predicted by sexuality-related identity threat, sexuality deflection as a sexuality management strategy, and identity resilience. Depression was predicted by sexuality-related identity threat, homophobic school bullying, and identity resilience. Anxiety was predicted by sexuality-related identity threat, sexuality acceptance as a sexuality management strategy, and general outness. Consistent with minority stress theory and identity process theory, the results show the significance of identity threat in the onset of poor mental health and the general importance of intrapsychic factors, over and above group-based variables, as risk or protective factors for mental health in gay and bisexual men in Lebanon. Culturally tailored mental health promotion strategies should focus on reducing sexuality-related identity threat, addressing societal stigma, and fostering protective factors, such as identity resilience and family support
Upskilling the old, a quarter-century on:Media literacies, AI and older people in public policy discourses
No full textThis paper provides a critical, historically situated investigation of policy discourses surrounding the digital inclusion of older people over the past quarter of a century – from the e-society of the early 2000s to today’s AI policy visions. Drawing on data from the AGEAI research project (www.anyage.ai), we investigate emerging debates on AI literacy in Europe, focusing on the role of digital skills in the AI-driven economies of the future. Specifically, we examine the AI strategies of four European countries: Germany, Spain, Poland and the UK, through textual analysis. Our focus is on older people, a growing social demographic mostly associated with healthcare and social welfare solutions. We situate current iterations of AI literacy in their historical-technological context, spanning over two decades of media literacy and digital inclusion policies. Our analysis reveals that AI skills are predominantly conceptualised as user capabilities, and ‘users’ are addressed as members of homogenous groups, echoing earlier policy narratives in which media literacies were framed in binary terms. Individuals either ‘have’ or ‘have not’ developed their digital media skills and capabilities for internet access and use. Older people are frequently characterised using ageist tropes, such as deficiencies in learning, and vulnerabilities to technological exposure. At the same time, they are positioned at the centre of an expanding market for technological solutions. We identify a new set of challenges for research and policy, arising from the fact that AI systems do not always require the active involvement of the ‘users’ on whom they are deployed and can further exacerbate social and digital inequalities related to ag

Postdigital Citizen Research:Surviving – Resisting – Flourishing (Special Issue Editorial)
No full textIt is now more than 30 years since Bill Readings (1997: 171) wrote presciently in The University in Ruins that ‘[c]hange comes neither from within nor from without, but from the difficult space – neither inside nor outside – where one is’. Most would agree that the position of universities in most societies and researchers in most universities has only become more problematic in the intervening period. This Special Issue focuses on a form of research which has become more prevalent during this time, perhaps because it inhabits precisely the kind of hybrid space Readings (1997) identified: citizen science, social science, and humanities. Exploring these overlapping areas both individually and through the collective term citizen research, the papers in the Special Issue examine its practices and positions in relation to research led by universities or other research hubs. They do this via postdigital perspectives which are ideally placed to understand and extend the hybridity and methodological possibilities of citizen research and identify commonalties with postdigital research approaches more generally (Jandrić et al. 2023b, 2023c)
Capturing contested mobile space:speed and injustice at the axes and planes
No full textCoastal urban edges, defined by significant spaces of mobilities, create tensions in the oppositions of flows of the practices of vision and action. Photography captures moments and tells fragments of stories. A closer, longer look of photographic images allows for otherwise un-noticed details. We notice the gendered automobilities at play in the coastal roadways and street spaces of Brighton, UK and Havana, Cuba, both renowned for their celebration of speed from car racing and testing. This article analyses selected photographic images from two archives situated in Brighton and Havana. We consider the impact of pre-determined and applied axes and planes of the spaces, considering the intentions before, and the imaginary afterlife of the images. Our analysis adds to an understanding of speed and injustice at the coastal urban edge.<br/
