Analyzing the use of Facebook among university libraries in Hong Kong

In recent years, many academic libraries have started adopting social media by, for example, establishing their own Facebook pages. Our research investigates the current Facebook usage among seven university libraries in Hong Kong. Using a mixed-method research approach, we examined the characteristics of academic libraries Facebook usage and its effectiveness to engage with their patrons, based on online observations and Web content analysis from the publicly available data of the Facebook pages.Our results indicated that most libraries in Hong Kong adopted Facebook as a marketing tool, yet the user engagement level in these pages is low. In addition, we also discovered that communication-related posts and video-type posts can attract the most attention of patrons. Based on these outcomes, we provided some recommendations on the application of Facebook for academic libraries.     

Are success and failure experiences equally motivational? An investigation of regulatory focus and feedback

The present study extended regulatory focus theory (Idson & Higgins, 2000) to an educational setting and attempted to identify individuals with high motivation after both success and failure feedback. College students in Hong Kong (N = 180) participated in an experiment with a 2 promotion focus (high vs. low) × 2 prevention focus (high vs. low) × 2 feedback (success vs. failure) design. The results showed that after success feedback, the students with promotion focus were more motivated than their counterparts with prevention focus. This pattern was reversed after failure feedback. However, the results failed to show that students high in both regulatory focuses were motivated after success as well as failure feedback. The findings are discussed with reference to the literature on flexibility of regulatory focuses. Practical and theoretical implications of feedback are also discussed.     

Microfluidic immunoassay for detection of serological antibodies: A potential tool for rapid evaluation of immunity against SARS-CoV-2

In December 2019, coronavirus disease 2019 became a pandemic affecting more than 200 countries and territories. Millions of lives are still affected because of mandatory quarantines, which hamstring economies and induce panic. Immunology plays a major role in the modern field of medicine, especially against virulent infectious diseases. In this field, neutralizing antibodies are heavily studied because they reflect the level of infection and individuals'' immune status, which are essential when considering resumption of work, flight travel, and border entry control. More importantly, it also allows evaluating the antiviral vaccine efficacy as vaccines are still known for being the ultimate intervention method to inhibit the rapid spread of virulent infectious diseases. In this Review, we first introduce the host immune response after the infection of SARS-CoV-2 and discuss the latest results using conventional immunoassays. Next, as an enabling platform for detection with sufficient sensitivity while saving analysis time and sample size, the progress of microfluidic-based immunoassays is discussed and compared based on surface modification, microfluidic kinetics, signal output, signal amplification, sample matrix, and the detection of anti-SARS-CoV-2 antibodies. Based on the overall comparison, this Review concludes by proposing the future integration of visual quantitative signals on microfluidic devices as a more suitable approach for general use and large-scale surveillance.

Who Makes the Choice? Rethinking the Role of Autonomy and Relatedness in Chinese Children’s Motivation

The importance of autonomy for children's motivation in collectivistic cultures has been debated hotly. With the understanding that autonomy is not equivalent to freedom of choice, 4 studies addressed this debate by investigating how socioemotional relatedness, choice, and autonomy were related to Chinese children's motivation. Study 1 (N = 56, mean age = 10.77 years), Study 2 (N = 58, mean age = 10.59), and Study 3 (N = 48, mean age = 10.53) found consistently that freedom of choice mattered less if children were socioemotionally close to the adults who made choices for them. However, Study 4 (N = 99, mean age = 11.27) showed that autonomy mattered at every level of socioemotional relatedness. These results suggested that socioemotional relatedness might have facilitated internalization and that children who did not have choice might still feel autonomous.     

The moderating effect of experience on the intention to adopt mobile social network sites for pedagogical purposes: An extension of the technology acceptance model

With numerous benefits of utilising mobile social network sites (SNSs) for learning purposes, limited studies have been conducted to determine the factors that influence the adoption of mobile SNSs in facilitating learning. Accordingly, the main purpose of this study is to explore the determinants of students’ behavioural intention to use mobile SNSs for their pedagogical purposes by utilising an extended version of Technology Acceptance Model. Furthermore, the moderating effect of users’ experience on their behavioural intention was investigated. Using a structured questionnaire, data were collected from 600 students from top-five public universities of Malaysia. The results revealed perceived task-technology fit as the great predictor of users’ intention and perceived usefulness. Although the moderating impact of students’ experience on the model found to be positive, it was not supported in this study. The contributions of this study both to the literature and practice are discussed.     

Exploring the Sources and Relationships that Propel Organisational Learning: An Investigation of Some Western Australian Schools

In exploring intricate relationships among environmental factors, internal school conditions and contextual variables that facilitate organisational learning, 90% of staff in six Western Australian secondary schools provided data for this exploratory study. Findings from the study not only shed light on the decade-old debate about the basic momentum for organisational change, but they also help rank-order the sources which initiate change. Additional analyses reveal factors from external environmental and internal school conditions that interact in bringing about organisational learning processes and outcomes in different contextual situations.
