RAISE Special Interest Groups (Early Career Researchers and Research & Evaluation) Collaboration: A Case Study

In the academic year 2022/23, the RAISE Special Interest Groups for Early Career Researchers and Research & Evaluation collaboratively developed a professional development programme for HE colleagues new to writing about student engagement. The diverse audience ranged from Early Career Researchers (ECRs) to colleagues new to academic writing including those interested in writing about Student Engagement. The programme featured three online events (alongside virtual on-demand support) covering themes around barriers and challenges to publication; enabling collaboration and co-creation across institutional/disciplinary contexts and the opportunity to participate in an academic writing workshop. This case study will present an account of the process and experiences of delivering these events looking into the barriers and challenges experienced by ECRs, the community-based, peer-learning approach adopted (CoPs) to address these with the aim to facilitate the publication process and make it more inclusive and accessible for (a diverse range of) participants. The example is framed and contextualised through relevant literature and a wider higher education backdrop of work-life balance, principles of staff-student partnership and a ‘publish or perish’ culture

Lived Experiences of a Hong Kong Physical Education Teacher: Ethnographical and Phenomenological Approaches

This study employed ethnographical and phenomenological methods to explore the lived experiences and career of a Hong Kong secondary school physical education (PE) teacher (Wharton) in order to embody his versatile roles through phenomenological description of a lived body itself and the lived world. The central research question is “How does a male secondary school PE teacher manage his work life and the embodiment of his professional roles?” Data collection techniques were in-depth interviewing, participant observation and field notes, participant’s reflection documentation and visual elicitation. Concepts of “play to learn,” “professional development” and “political empowerment” were used to examine Wharton’s lived experiences and career. Themes such as Static Gestalt, Dynamic Gestalt, Style Gestalt and Reversibility Gestalt were identified. This study may inform literature on sociological perspectives and the life histories of PE teachers and applicable to other teachers as they adapt to environmental changes in other settings

Physical literacy-based intervention for older adults:a cluster randomized controlled trial study protocol

The ageing population creates concerns and challenges worldwide. The large number of older adults (aged over 65) in Hong Kong continues to rise as people live longer. This may result in heavy burdens on public services and problems such as a shortage of medical resources. The purpose of this study is to implement a physical literacy-based intervention among older adults in Hong Kong in order to achieve the goal of health promotion. A two-arm cluster randomized controlled trial will be employed in this proposed study. Ten daycare centers for the older adults in Hong Kong will be invited to participate in this study. The intervention group will receive functional fitness training and mastering physical literacy class twice a week with buddy peer support, and they will be asked to keep a reflective writing journal on a daily basis for 12 weeks in total. Participants will be evaluated at baseline (week 0), post-intervention (week 12), and at 6-week follow-up (week 18). This will consist of objective and self-reported measures covering elements within physical literacy (i.e., physical competence, motivation and confidence, knowledge and understanding) and also physical activity levels on an individual basis. The study intends to introduce a conceptual framework of physical literacy for the older adults through an intervention that allows older people to develop daily behaviour habits, which should promote active ageing for the older adults and greater self-esteem in later life. After this study, participants may share their positive experiences, and encourage their peers in the community to become physically literate in the future. In the long run, due to the feasibility and sustainability of these potential programs, this proposed study has the potential to connect seniors through social engagement and contribute to healthy living.

Structures of EccB\u3csub\u3e1\u3c/sub\u3e and EccD\u3csub\u3e1\u3c/sub\u3e from the Core Complex of the Mycobacterial ESX-1 Type VII Secretion System

Background: The ESX-1 type VII secretion system is an important determinant of virulence in pathogenic mycobacteria, including Mycobacterium tuberculosis. This complicated molecular machine secretes folded proteins through the mycobacterial cell envelope to subvert the host immune response. Despite its important role in disease very little is known about the molecular architecture of the ESX-1 secretion system. Results: This study characterizes the structures of the soluble domains of two conserved core ESX-1 components – EccB1 and EccD1. The periplasmic domain of EccB1 consists of 4 repeat domains and a central domain, which together form a quasi 2-fold symmetrical structure. The repeat domains of EccB1 are structurally similar to a known peptidoglycan binding protein suggesting a role in anchoring the ESX-1 system within the periplasmic space. The cytoplasmic domain of EccD1has a ubiquitin-like fold and forms a dimer with a negatively charged groove. Conclusions: These structures represent a major step towards resolving the molecular architecture of the entire ESX-1 assembly and may contribute to ESX-1 targeted tuberculosis intervention strategies

Intrinsic Structural Features of the Human IRE1α Transmembrane Domain Sense Membrane Lipid Saturation

Activation of inositol-requiring enzyme (IRE1α) is an indispensable step in remedying the cellular stress associated with lipid perturbation in the endoplasmic reticulum (ER) membrane. IRE1α is a single-spanning ER transmembrane protein possessing both kinase and endonuclease functions, and its activation can be fully achieved through the dimerization and/or oligomerization process. How IRE1α senses membrane lipid saturation remains largely unresolved. Using both computational and experimental tools, we systematically investigated the dimerization process of the transmembrane domain (TMD) of IRE1α and found that, with help of the serine 450 residue, the conserved tryptophan 457 residue buttresses the core dimerization interface of IRE1α-TMD. BiFC (bimolecular fluorescence complementation) experiments revealed that mutation on these residues abolished the saturated fatty acid-induced dimerization in the ER membrane and subsequently inactivated IRE1α activity in vivo. Therefore, our results suggest that the structural elements of IRE1α-TMD serve as a key sensor that detects membrane aberrancy

Attitude, acceptability and knowledge of HPV vaccination among local university students in Hong Kong

© 2016 by the authors; licensee MDPI, Basel, Switzerland. The Human Papillomavirus (HPV) vaccine has the great potential to prevent HPV-related infections for millions of women and men worldwide. However, the success of the vaccine is highly dependent on the vaccination rate. Factors influencing the attitudes of undergraduate students towards HPV vaccination should be studied. This is a cross-sectional survey that was conducted to estimate the HPV vaccination rate among undergraduate students in Hong Kong, and to identify the predictors of their attitude towards HPV vaccination. The results showed that the HPV vaccination rate was 13.3%. Factors related to knowledge of vaccination were the main predictors of the studentsâ attitude towards vaccination (there were seven predictors, with B = 1.36 to 2.30; p < 0.05), followed by gender (B =-1.40; p < 0.05), acceptable maximum price (B = 0.35; p < 0.05), and willingness to receive the HPV vaccine if it can protect against cervical/anal cancer and genital warts (B =-1.90; p < 0.001).Theregressionmodelthatwasdevelopedbasedonthepredictorshadamoderateeffect size (adj-R 2 = 0.33). To conclude, the HPV vaccination rate among undergraduate students in Hong Kong was low. They should be provided with more active education and activities to promote HPV vaccination to improve their knowledge on the subject.Link_to_subscribed_fulltex

Metaheuristic design of feedforward neural networks: a review of two decades of research

Over the past two decades, the feedforward neural network (FNN) optimization has been a key interest among the researchers and practitioners of multiple disciplines. The FNN optimization is often viewed from the various perspectives: the optimization of weights, network architecture, activation nodes, learning parameters, learning environment, etc. Researchers adopted such different viewpoints mainly to improve the FNN's generalization ability. The gradient-descent algorithm such as backpropagation has been widely applied to optimize the FNNs. Its success is evident from the FNN's application to numerous real-world problems. However, due to the limitations of the gradient-based optimization methods, the metaheuristic algorithms including the evolutionary algorithms, swarm intelligence, etc., are still being widely explored by the researchers aiming to obtain generalized FNN for a given problem. This article attempts to summarize a broad spectrum of FNN optimization methodologies including conventional and metaheuristic approaches. This article also tries to connect various research directions emerged out of the FNN optimization practices, such as evolving neural network (NN), cooperative coevolution NN, complex-valued NN, deep learning, extreme learning machine, quantum NN, etc. Additionally, it provides interesting research challenges for future research to cope-up with the present information processing era
