Research has shown that English language proficiency (ELP) plays a crucial role in the psychological well-being of international students (e.g. Li et al., "Journal of International Students, "4(4), 301-313, 2014). However, few studies have reported positive correlations between their improved English skills and well-being. The present study examines how a new pedagogy called personalised autonomous (PA) model can induce a virtuous cycle in international PhD students to enhance their English language proficiency and consequently, their well-being. We collected both quantitative and qualitative data from two groups of students: those who experienced the PA model in a course entitled Personalised English Language Enhancement (PELE) and those who did not. We conducted surveys at the beginning and end of the term to compare entry and exit data. Comparison of the entry and exit survey data for PELE students showed significant improvements across almost all dependent variables including self-efficacy, well-being and a sense of belonging to the university community. In contrast, the non-PELE students did not significantly improve in any variable. In focus groups, students indicated how their improved communicative confidence sparked a virtuous cycle leading to greater well-being and a stronger sense of community. Our data strongly suggests that ELP extends beyond mere linguistic ability; it embodies a dynamic interplay between one's language skills and their self-confidence. Diminished confidence may trigger a vicious cycle of fear of communication, unwillingness to engage, unproductive research, and estranged relationships with supervisors. Therefore, it is imperative for educators and policymakers to critically review and enhance their approaches to supporting the ELP of international PhD students.

Summary: Fat and Dachsous are evolutionarily conserved atypical cadherins that regulate polarized cell behaviors. In the Drosophila wing, they interact heterophilically between neighboring cells, localize asymmetrically to opposite cell ends, and control wing shape by regulating oriented cell rearrangements and divisions. Fat and Dachsous have 34 and 27 cadherin repeats, respectively, and previous work has identified trans interactions between their first four cadherin repeats. Here, we identify a second heterophilic binding site in their C-terminal cadherin repeats and show the conservation of this binding site in human Fat4 and Dachsous1. We provide evidence that both N- and C-terminal binding sites regulate the stability of Fat-Dachsous binding interactions and show that the N-terminal binding sites are partly dispensable for Fat-Dachsous function in vivo. Finally, we provide in vivo confirmation that the N-terminal repeats interact in an anti-parallel manner. We propose that multiple binding sites promote the clustering of Fat and Dachsous into a lattice-like array.

Emergency food planning is an emerging field of study and practice evolving from lessons learned about the need to be prepared to respond to increased food insecurity in the face of emergency events. In this era of climate change, geo-political conflicts, and growing inequality, disruptions to the global food system are occurring more frequently. Many of these disruptions have the potential to impact food access on a large scale, a reality that communities need to be ready for through prepara­tion to mitigate impacts. Like other municipalities around the world, the city of Thunder Bay in Northwestern Ontario, Canada, and its surround­ing areas were caught unprepared by the impacts of the COVID-19 pandemic on food insecurity. Prior to the pandemic, there was no coordinated body to address a sudden increase in food insecurity, partic­ularly among already vulnerabilized populations. In late 2020, Thunder Bay + Area Food Strategy (TBAFS), the regional food policy council, led the coordination of emergency food response and researched the early emergency food response that occurred during the COVID-19 pandemic. Find­ings from this research identified the need for a collaborative Emergency Food Plan that brought together the municipality and a range of civil soci­ety organizations, institutions, and agencies. Acting on this research, the TBAFS coordinated the devel­opment of an Emergency Food Plan for the region, leveraging a group of primary partners who make up key components of civil society’s food access infrastructure. This article provides an over­view of this process in the context of existing research and literature along with lessons learned throughout the process.

Abstract Background Existing traditional cognitive screening tools for dementia have various limitations, including overreliance on tests assessing verbal memory and, to a lesser extent, on some aspects of executive functioning. Comprehensive neuropsychological assessment is sensitive to impairment but time-intensive and expensive. Virtual reality may provide a dynamic and unique understanding of cognitive performance and increase the ecological validity of cognitive assessment. The use of virtual reality in screening for cognitive function in older persons is promising, but evidence for its use remains sparse. Objective Our primary aim was to examine the feasibility and acceptability of a newly developed, virtual reality assessment module, ‘Leaf Café’, a computer-based program that assesses cognition in an engaging, efficient, and ecologically relevant way. The secondary aim was to assess the ability of the module to discriminate between performances of younger and older adults. Methods A cross-sectional study was carried out in Sydney, Australia, targeting adults aged 18 years and above. Participants completed a traditional cognitive screening tool (Telephone Interview for Cognitive Status-Modified, TICS-M) and Leaf Café, a low-immersive virtual reality module designed to evaluate learning and memory, perceptual-motor function, and executive functioning. The total performance score for each participant, ranging from 0 to 180, was correlated with their cognitive performance assessed by TICS-M, using Pearson’s correlation coefficient. Following module completion, participants were presented with an open and closed-question survey to capture their perceptions, attitudes, and feedback on the module, encompassing practicality, acceptability, and enjoyment. Both descriptive and content analyses were employed to interpret the obtained data. Results A sample of 131 participants (mean age 54.9 years, SD = 20.8, range 20–85) took part. The majority were female (71.8%) and born in an English-speaking country (75.8%). The mean amount of time spent in the module was 32.8 min (SD = 13.3) with a mean module score of 107.6 (SD = 38.7). Most participants completed the highest level (5; 80.5%). There was a significant correlation between Leaf Café total scores with TICS-M cognitive scores overall, and for both younger (aged 18–64 years) and older adult (aged 65 + years) groups. No significant difference was found on performance between age groups on TICS-M performance, however, younger adults had significantly better performance on the Leaf Café module than older adults (M = 124.1 vs 95.9; p

Abstract Background An informed understanding of older adults’ perceptions of the impact (positive or negative) of recurrent COVID-19 long lockdowns is important for the development of targeted interventions and resources for future restrictions. This study aimed to understand self-reported impacts of COVID-19 recurrent restrictions on older adults and how technology has been used to mitigate these. Methods A cross-sectional national study of 257 community-dwelling older Australians based in Victoria (mean age = 67.6 years [SD = 7.2]; 20.6% male) completed an online or postal survey as part of a larger study examining the physical and mental health impacts of a second extended COVID-19 lockdown period. This secondary analysis reports on the findings from free-text responses to two open-ended questions included in that survey that asked participants to comment on the greatest impacts of the COVID-19 lockdowns (positive or negative) and the role of technology in supporting their wellbeing during this time. Responses were collected between July and September 2020. Data were analysed using content (COVID-19 impacts) and thematic (role of technology) analysis. Results Respondents gave more negative responses (75.5%) than mixed (15.2%) and positive responses (6.2%) in reporting on the biggest impact of COVID-19 lockdowns. Inductive content analysis revealed two first-order main categories (Positive impacts and Negative impacts). Axial coding of main categories showed five second-order categories (Environmental, Physical Health, Social, Mental Health, and Personal) for both negative and positive main categories (totalling 10 second-order categories). Overall, respondents highlighted social loss as the key negative experience (70%), with acute feelings of social isolation contributing to negative impacts on mental wellbeing. The most commonly reported positive impact reported (11%) was having more time for relationships, relaxation, and new hobbies. Technology was primarily used to sustain socialisation and provide access to essential resources, services, and goods, which respondents perceived to contribute to maintaining their wellbeing. Conclusions Findings suggest a critical need for interventions that address the social loss experienced by older adults during COVID-19 recurrent lockdowns, particularly to alleviate the associated negative impact on mental wellbeing. Recognising the positive aspect of increased time for relationships and leisure activities indicates potential areas for resilience-building strategies. The pivotal role of technology in mitigating adverse effects highlights its significance in building social connections and supporting overall wellbeing during challenging times. These implications can guide future efforts to enhance older adults’ resilience, mental health, and holistic wellbeing in future public health crises.
