ABSTRACT
Total waste from human activities, including waste plastics, is huge in Hong Kong. In particular, as a result of the prevention and control measures implemented during the COVID-19 pandemic, take-away meals increased tremendously in Hong Kong, generating disposable plastic tableware (DPT). Although Hong Kong has a charging scheme for plastic bags, it does not have a scheme for plastic tableware. Therefore, this study aimed to understand the attitudes and behavior of people in Hong Kong toward DPT. Our study focused on undergraduate students in Hong Kong, given that they will play a significant role in the future of environmental sustainability. The attitudes and behavior of Hong Kong undergraduate students toward DPT were examined through an online survey with 385 respondents. A multiple stepwise regression was conducted to investigate whether cognitive attitude formation factors could explain the sustainable attitudes formed by undergraduate students in Hong Kong. The survey results revealed that most undergraduates considered DPT to be one of the major causes of environmental damage in Hong Kong;however, many of them, particularly those who strongly agreed with this statement, said that the problem of DPT did not affect their quality of life. The regression analysis showed that imposing a DPT charge would be the most significant driver to reduce its use. The research findings identified gaps between attitudes and behavior regarding the use of DPT and the factors influencing sustainable DPT consumption.
ABSTRACT
PurposeThe purpose of this research is to investigate the short-term capital markets' reactions to the public announcement first local detection of novel corona virus (COVID 19) cases in 12 major Asian capital markets.Design/methodology/approachUsing the constant mean return model and the market model, an event study methodology has been implied to determine the cumulative abnormal returns (CARs) of 10 pre and post-event trading days. The statistical significance of the data was assessed using both parametric and nonparametric test statistics.FindingsFirst discovery of local COVID 19 cases had a substantial impact on all 12 Asian markets on the event day, as shown by statistically significant negative average abnormal return (AAR) and cumulative average abnormal return (CAAR). The single factor ANOVA result has also demonstrated that there is no variability among 12 regional markets in terms of short-term market responses. Furthermore, there is little evidence that these major Asian stock market indices differ significantly from the FTSE All-World Index which might suggest possible spillover impact and co-integration among the major Asian capital markets. The study further discovers that market capitalization and liquidity did not have any significant impact on market reaction to announcement.Research limitations/implicationsThe study's contribution might have been compromised by the absence of socio-demographic, technical, financial and other significant policy factors from the analysis.Practical implicationsThese findings will be considerably helpful in tackling this unprecedented epidemic issue for personal and institutional investors, industrial and economic experts, government and policymakers in assessing the market in special circumstances, diversifying risk and developing financial and monetary policy proposals.Originality/valueThis paper is the first to examine the effects of local COVID 19 detection announcement on major Asian capital markets. This study will add to the literature by investigating unusual market returns generated by infectious illness outbreaks and the overall market efficiency and investors' behavioral pattern of major Asian capital markets.
ABSTRACT
COVID-19 vaccines against the earlier strains of SARS-CoV-2 are now available. However, breakthrough infections can still occur due to waning antibodies and immune escape by new variants. We assessed humoral immune responses to the mRNA (BNT162b2) and inactivated (CoronaVac) vaccines in our healthcare worker cohort (HCW). We recruited HCWs from public and private healthcare institutions across Hong Kong and collected blood samples at enrolment and every 6 months from June 2020 to June 2022. A subset of volunteers provided blood samples between 10 – 42 days after each dose of vaccine. Immune responses to vaccination were measured as SARS-CoV-2 binding antibodies detected by an enzyme-linked immunosorbent assay (ELISA) and SARS-CoV-2 neutralising antibodies by surrogate virus neutralization test (sVNT) and plaque reduction neutralization test (PRNT). Among the 1,736 HCWs enrolled in our cohort, 252 HCWs provided pre- and post-vaccination blood samples after each dose of either vaccine. Two doses of BNT162b2 generated levels of neutralizing antibodies (sVNT inhibition = 96.8%, range = 42.8%, 98.2%) comparable to those generated by natural infections in the first wave (sVNT inhibition = 84.0%, range = 32.9%, 93.8%). Similar levels were achieved with three doses of CoronaVac (sVNT inhibition = 95.3%, range = 64.7%, 98.3%) and heterologous vaccination with two doses of CoronaVac followed by a booster dose of BNT162b2 vaccine (sVNT inhibition = 97.0%, range = 85.8%, 97.7%). These antibody levels waned faster after second doses and slower after third doses for both vaccines. The BNT162b2 vaccine and CoronaVac vaccines can generate robust antibody responses comparable to natural infections. Three doses of the CoronaVac vaccine, or a heterologous boost with the BNT162b2 vaccine following two doses of the CoronaVac vaccine are required to achieve similar levels of neutralising antibodies in vaccinees who received two doses of the BNT162b2 vaccine.

ABSTRACT
The study compares the effectiveness, popularity, and ease of applicability of different learning tools in virtual classrooms among university teachers and students concerning the users' technological literacy and training, as well as equipment support offered by the universities during the pandemic. Comparisons between face-to-face teaching in classrooms and online virtual classrooms will be drawn concerning limitations, incentives, motivation, and effectiveness toward learning. This study also leads to the question of future course development by exploring the possibility of course design and assessment restructuring with a switch to online education with the new mode of technology as the trend.
ABSTRACT
China has two repressive systems that exist simultaneously: the highly coercive and surveilled system in Xinjiang, and the trust-based model of everyday repression prevalent throughout the rest of the country. The trust-based model has undergirded grassroots governance in China and facilitated the routine implementation of Zero-Covid. Drawing on a protest event dataset, I analyze the key characteristics of the covid protests erupted in November and December of 2022, before situating them in the larger context of China's political future under Xi Jinping's rule. The Chinese Communist Party (CCP) has responded to the protests with a combination of concession and repression. But neither the carrot nor the stick is able to fundamentally address the deep-rooted social problems or halt the tide of dissent. Coupled with structural economic challenges, these protests could be the harbinger of a new era of contentious state-society relations in China, the seeds of which were sown years ago–only precipitated and underscored by the CCP's covid debacle.
ABSTRACT
The Zoom format was not only expedient, but also essential to The Plague: it enabled Wang to foster international solidarity while at the same time threatened to turn the production into a performance of precarity, which echoed our shared struggle in a global pandemic. The daring experiment of staging a live performance across five time zones also came at a cost: minor technical glitches, freezes, and time lags transpired in the performance that I saw. [...]eating the food that they prepared at the beginning of the performance, they revisited the moment when the everyday and the theatrical overlapped and bade goodbye to audience members who bore witness to the fight together.

ABSTRACT
Background: Since the start of the COVID-19 epidemic in late 2019, there have been more than 152 affected regions and countries with over 110,000 confirmed cases outside mainland China. Methods: We analysed COVID-19 cases among travellers from mainland China to different regions and countries, comparing the region- and country-specific rates of detected and confirmed cases per flight volume to estimate the relative sensitivity of surveillance in different regions and countries. Results: Although travel restrictions from Wuhan City and other cities across China may have reduced the absolute number of travellers to and from China, we estimated that more than two thirds (70%, 95% CI: 54% - 80%, compared to Singapore;75%, 95% CI: 66% - 82%, compared to multiple countries) of cases exported from mainland China have remained undetected. Conclusions: These undetected cases potentially resulted in multiple chains of human-to-human transmission outside mainland China.
ABSTRACT
Another point of view from Dr. Hoshi from the Stanford Online High School demonstrated that current situation compels people to learn more about online education than ever before while at the same time arouses a new round of skepticism toward it. [...]this ineffectiveness, in turn, is going to promote the development of online education faster and better with the really good remaining methods and approaches. In the long run, the main problem would transfer to the professional development of teachers and students and the technical capacity building of institutions. "Because people in higher education systems should try and explore numbers of tools, more importantly, to make sense of teaching and learning in support of technologies,” as several participating scholars have echoed. [...]there were many universities already providing online programs for students, and these programs were assumed to have no essential difference between face-to-face teaching and online teaching. [...]some participants suggested that faculties would ideally like to use one comprehensive tool for online teaching instead of combining multiple different technologies.
ABSTRACT
PurposeThis research studies the influence of the COVID-19 pandemic on the operation management of Hong Kong academic libraries for understanding the difficulties and challenges for librarians to adapt to the special arrangements during the pandemic.Design/methodology/approachQualitative semi-structured interviews were conducted with librarians in major universities and higher education institutions of Hong Kong. Participants were interviewed either in the face-to-face format or text-based format.FindingsParticipants provided a broad scope about the actual library management and operation changes during the COVID-19. According to the respondents, the most challenging problem for librarians during COVID-19 was to strike a balance between concerns of library staff and users. While they described how these arrangements and changes affected the service quality of academic libraries from different perspectives, the pandemic situation also brought some opportunities, such as pushing the digitalization of all collections and using online resources for future development. A hybrid model for library service would be more common in the future with more demands toward online resources and digital collection, in which academic libraries should be prepared after the pandemic.Originality/valueThis paper provided broad insights into library management and the future development of academic libraries for the post-COVID-19 period. There are scant studies of this topic, especially in an Asian metropolis context with dense population, small campus and limited library physical spaces.
ABSTRACT
PurposeDuring the coronavirus disease 2019 (COVID-19) pandemic, museums, as public gathering places for citizens, have encountered unprecedented difficulties due to limitations to operate as usual for their traditional exhibitions and curations. Thus, museums made corresponding emergency attempts to accelerate digital resource and service platform constructions. Such difficulties aroused many potential problems with the applicability of electronic resources and the mismatch between user expectations and museum services. This study investigates the challenges faced by Hong Kong museums under COVID-19, emergency responses and deliberate practices of Hong Kong museums from the perspective of both museum staff and visitors, and COVID-19's influence on the roles and functions of Hong Kong museums.Design/methodology/approachQualitative interviews with museum staff and visitors were conducted to collect opinions and experiences in the construction and maintenance of museums during the pandemic. Further thematic analyses of museum websites, evaluations, and suggestions were formulated guided by the PEST (Political, Economic, Social, Technological) and AIDA (Attention, Interest, Desire, Action) models.FindingsFindings revealed many online interactions and offline renovations, but the perceptions of visitors and staff differed considerably. While online resources and virtual museums were expanded and well received, long-term prohibitions and repressions drove physical visit desire. Participants emphasized finding a balance between user expectations and realistic practices.Originality/valueScant studies focus on the impact of COVID-19 on the cultural industry, especially in East Asia. This study also highlights new practices of digitalization and the challenges of functional transformation. The authors' findings and suggestions provide hints to optimize the curation of information resources and improve museum service quality in the new digital era. This study also serves as a reliable and meaningful record of COVID-19 impacts on Hong Kong museums.
ABSTRACT
This article examines the link between the mandatory live-in policy and the unsafe working and living conditions of women migrant domestic workers. This policy has been rationalised on the principles of the inviolability of the private home and challenges around regulating and enforcing labour protections in the homeworkplace but has, in practice, increased migrant domestic workers' precarity and exploitation. Drawing on empirical research in Singapore and Hong Kong, the article demonstrates how the live-in policy operates in tandem with inadequate labour and migration regulations to produce a situation where poor working and living conditions are an enduring part of workers' employment and everyday lives. It contributes to research that has highlighted the gendered dynamics and exclusionary bordering practices that shape waged domestic labour, and considers the implications this may have for the well-being and security of women migrant domestic workers.
ABSTRACT
Powerful, imaginative, and long-lasting, the half-year mobilisation and its iconography are hard to forget, and the ongoing political crackdown keeps our memory alive with constant republications of photographs and video clips of the events. Since the outbreak of the Covid-19 pandemic and the proclamation of the National Security Law (NSL) on 30 June 2020, protests have, however, almost disappeared from Hong Kong's public spaces. [...]many films, books, and artworks have vanished from screening venues, shops, and libraries. Soon after the end of the movement, two anonymous books documented these ephemeral displays challenging authorities and urban order (Abaddon 2020;Guardian of Hong Kong 2020). [...]in October 2021, the Film Censorship Ordinance was amended to align with the NSL (Ho 2021b).
ABSTRACT
First example of how to use the expression ‘安分守己' (‘remain in one's proper sphere') on the Baidu Chinese–English translation site (emphasis in the original) (Image 1) A meme that circulated on WeChat during the 2022 Omicron outbreak in Shenzhen. Considering Shanghai's zero-Covid crisis, which began just as Shenzhen reopened, the latter's success (on its own terms) has provided a robust model of how the government used rational, scientific principles to achieve public health goals. [...]it has served to mute accounts of policy failure in other cities, especially Shanghai. [...]during the outbreak, social media discussions of and frequent debate about out-of-place mobilities and policy breakdowns showed the implicit social contract between the CCP and the people, making visible Shenzhen's implicit moral geography.
ABSTRACT
[...]as there is no need to rent shop space and the seller purchases products only after an order has been paid, it is a business that requires no advanced capital and thus is easily accessible to young and poor people. [...]it involves an almost exclusively one-way flow of Taiwan-made commodities to Hong Kong and a flow of cash in the opposite direction. Taiwanese snacks, fruit, and creative cultural products are also increasingly popular in the city, partly for political reasons. Since the 2014 Umbrella Movement, Taiwan's government and civil society organisations have stood behind Hongkongers' struggle for democracy, incurring criticism from the Chinese authorities. According to the explanation provided on RS International's website, the initials ‘RS' refer to ‘Radical Solider' and ‘Rebuild System', indicating their radical motivations.
ABSTRACT
To test for arbitrage opportunities and market efficiency in the Hong Kong money, stock, and real estate markets, we find that the money market stochastically dominates both the stock and real estate markets. Furthermore, the real estate market dominates the stock market, the money market dominates nearly all the efficient frontier portfolios, none of the efficient portfolios dominates the money market, and the money market also dominates the equal-weighting portfolio. This infers that in some cases investors could achieve higher expected ex-ante utility by investing in an individual asset rather than a portfolio. Our conclusions drawn from the pre-COVID-19 period are the same as those drawn from the entire period and the conclusions drawn from the COVID-19 period are the same as those drawn from the entire period except that the money market only stochastically dominates some of the efficient frontier portfolios. Our findings question diversification benefits in the Hong Kong capital market during our sample period, including both the pre-COVID-19 and COVID-19 periods.
ABSTRACT
PurposeCOVID-19 pandemic has exposed that even the best of the developed nations have surrendered to the devastations imposed on the global supply chains. The purpose of this study is to explore how COVID-19 has exaggerated the supply chain of production and distribution of Taiwan-based face masks and also investigate the conscientious factors and subfactors for it.Design/methodology/approachIn this study, an analytical hierarchy processes (AHP)-based approach has been used to assign the criterion weights and to prioritize the responsible factors. Initially, based on 26 decision-makers, successful factors were categorized into five main categories, and then main categories and their subcategories factors were prioritized through individual and group decision-maker's contexts by using the AHP approach.FindingsThe results of this AHP model suggest that "Safety” is the most important and top-ranked factor, followed by production, price, work environment and distribution. The key informers in this study are stakeholders which consist of managers, volunteers, associations and non-governmental organizations. The results showed that good behavior of the employees under the "Safety” category is the top positioned responsible factor for successful production and distribution of face masks to the other countries with the highest global percentage of 15.7% and using sanitizers to protect health is the second most successful factor with the global percentage of 11.7%.Research limitations/implicationsThe limitations faced in this study were limited to only Taiwan-based mask manufacturing companies, and it was dependent on the decisions of the limited company's decision-makers.Originality/valueThe novelty of this study is that the empirical analysis of this study has been based on a successful Taiwan masks manufacturing company and evaluates the responsible factors for the production and distribution of Taiwan masks to other countries during COVID-19.
ABSTRACT
Purpose: The purpose of this paper is to study the interlinkages between the cryptocurrency and stock market by characterizing their connectedness starting from January 1, 2018 to December 31, 2021. Design/methodology/approach: The author employs a time-varying parameter vector autoregression (TVP-VAR) in combination with an extended joint connectedness approach. Findings: The pandemic shocks appear to have influences on the system-wide dynamic connectedness, which reaches a peak during the COVID-19 pandemic. Net total directional connectedness suggests that each cryptocurrency and stock have a heterogeneous role, conditional on their internal characteristics and external shocks. In particular, Bitcoin and Binance Coin are reported as the net receiver of shocks, while the role of Ethereum shifts from receivers to transmitters. As for the stock market, the US stock market stays persistent as net transmitters of shocks, while the Asian stock market (including Hong Kong and Shanghai) are the two consistent net receivers. During the COVID-19 pandemic shock, pairwise connectedness reveals that cryptocurrencies can explain the volatility of the stock markets with the impact most severe at the beginning of 2020. Practical implications: Insightful knowledge about key antecedents of contagion among these markets also help policymakers design adequate policies to reduce these markets' vulnerabilities and minimize the spread of risk or uncertainty across these markets. Originality/value: The author is the first to investigate the interlinkages between the cryptocurrency and the stock market and assess the influences of uncertain events like the COVID-19 health crisis on the dynamic interlinkages among these two markets. The author employs the TVP-VAR combined with an extended joint connectedness approach.
