Collection, as the first stage of the recycling process, and pre-processing to increase waste stream purity constitute key operations for achieving high recycling rates and a closed loop in the circular economy. For wastepaper recycling in Hong Kong, it is the semi-formal-informal recycling (SFIR) sector that plays a central role in both stages. This study analyses the so far little explored SFIR stakeholder network in Hong Kong and sheds light on value chains, recovered waste paper quantities and the impact of policies on the sector. The findings show that SFIR stakeholders reclaim 55.6 t/recycling station/month of wastepaper and thereby achieve about a 5.7 times higher reclaim rate than the formal-private recycling system. Critical to this achievement is the SFIR transaction network, which enables its stakeholders to develop a value chain and thereby generate an added value of around 1900 HKD (243.9 USD/t) for wastepaper. Given limited circular structures in Hong Kong, financial subsidies are critical to sustain the SFIR's operations over the short-term. However, over the long-term legalization and integration of its stakeholders are necessary to ensure an economically and socially sustainable wastepaper recovery system in Hong Kong. [Display omitted] • Qualitative & quantitative analysis of the semi-formal-informal recycling (SFIR) sector. • The SFIR's wastepaper value chain achieves a cumulative added value of 1900 HKD/t. • The SFIR recovered 5.7 times higher capacities than the formal system in 2021. • Financial support can enhance the SFIR sector's recovery capacities.

How did Chinese leaders Deng Xiaoping and Zhao Ziyang feel about Hong Kong? The existing literature has tended to see the Sino-British negotiations over the future of Hong Kong through the economic lens favoured by the British side and described the Chinese side as primarily motivated by nationalism. However, 'nationalism' remains a vague concept in need of further definition. This paper focuses on the Chinese side of the negotiation table. It unpacks what 'nationalism' meant to Deng and Zhao within the context of the negotiations by examining three interrelated components: history, identity and emotion. This paper then analyses how the Chinese side used history, identity and emotion strategically during the negotiations, focusing on the September 1982 leaders' meetings as a case study. Adopting a constructivist lens, this paper examines historical documents against frameworks and theories from the social sciences, producing an interdisciplinary analysis of Chinese negotiation tactics. It unravels how China's leaders used the country's past to broadcast the Party's stance to the people, bolster their leadership position and win the advantage over Britain in the Hong Kong negotiations.

The development of efficient and reliable online assessments has become increasingly important in the digital era. We developed a 10-min online word reading assessment of global English based on the existing paper-and-pencil version of our English silent word reading test. The test includes two parts, namely, random word recognition and contextual word reading. A total of 889 participants (437 children and 392 adults; 62.7% female) took part in the study. They were from various regions including mainland China, Hong Kong SAR, Macau SAR, Poland, the United States, and the Philippines. Reliability and validity analyses on various demographics samples (by age and country/region of origin) demonstrated that the WordSword Test is highly reliable and valid (e.g., the correlation of this test with other English reading measures were above.80). Education level was positively correlated with test performance, while the correlations between age and test performance were not consistent. Ninety-seven children participants also took the paper-and-pencil version of the WordSword Test. The correlation between performances on the online and paper-and-pencil versions of the test was.879, one year apart. With more children and adults taking the WordSword Test, we ultimately hope to establish norms by area, grade level, and age. [ABSTRACT FROM AUTHOR]

In the Hong Kong Chief Executive's 2020 Policy Address, the Hong Kong Special Administrative Region (HKSAR) Government implemented strategies to integrate arts and technology as a new trend in cultural development. With the co-existence of a governmental initiative in 'arts and technology' ('arts tech') development and the rapid advancement of new technologies, it is frequently seen that new technologies (e.g., virtual reality [VR] and augmented reality) have been widely adopted in interactive media art productions in Hong Kong. Drawing on ethnographic research on a commercial virtual event, and a VR theatre performance produced by a Hong Kong cross-media creative studio, this study unveils discrepancies existing between government officials, commercial marketers, and art creators, ranging from objectives to practices in applying technologies to virtual art production. The juxtaposition of a market-driven commercial virtual campaign and the Chinese nationalist agenda embodied in the government-funded arts tech project reflects how the socio-historical background and changing political situation in Hong Kong extends its postcolonial neoliberal nationalism (PNN) to the arts tech arena. The contribution of this paper is two-fold: first, by adopting 'China as method' as epistemological analysis, the mediation of PNN by arts tech explains a 'southbound imaginary' in Hong Kong's arts and cultural practices through a changing relationship between Hong Kong and mainland China. Second, in contrast to the current scholarship focusing on human governance in the formation of neoliberal nationalism, this paper underscores the 'power' of techno-cultural material in mediating the neoliberal nationalism of Hong Kong, after its reversion to China, through arts tech development.

A considerable body of work now exists on the role that identity plays in understanding teachers and teaching. Developing and sustaining teacher identities in higher education can, however, be challenging given the subordinate positioning of teaching in some educational contexts. Despite the growth of English for Academic Purposes (EAP) programmes in many parts of the world, recent research suggests that EAP practitioners are especially vulnerable to being assigned marginalized identities within the academy. Therefore, this paper reports the results of a study which used a short story approach to investigate the tensions and triumphs one EAP practitioner in Hong Kong experienced in constructing her language teacher identities (LTIs). Findings suggest that her identity tensions and struggles take place across space and time and play out at different scales, including classrooms, educational institutions, and within broader societal discourses. However, the short stories presented in this paper speak not only of tension and struggle, but also of determination and resilience to construct LTIs in the academy. Consequently, the results of this study can help to raise awareness amongst stakeholders, including policy makers, leaders of higher education institutions, and language teaching practitioners, of how they can support and sustain the construction of LTIs within the academy. Implications for professional learning for language teaching practitioners and suggestions for future research are considered. [ABSTRACT FROM AUTHOR]

Modular integrated construction (MiC) is an innovative construction method that is widely used in practice, but high transportation cost is an obstacle to its wider implementation. This paper is motivated by the real-world need for a scientific approach for MiC transport scheduling, and addresses the practical problem of how to achieve on-time door-to-door MiC delivery in an economical manner. An innovative integer programming model is formulated with the objective of minimising the total transportation costs, including trailer rental, fuel costs, and worker salaries. A case study based on Hong Kong data validates that the developed model can be efficiently solved for problems of practical size. The results also demonstrate that the derived MiC schedule plan can reduce transportation costs by 58.7% compared with a just-in-time (JIT) strategy, thus bringing great economic benefits to off-site construction practitioners. Useful managerial implications related to on-site MiC storage areas are derived through sensitivity analysis. Overall, this paper sets the ground for the application of mathematical programming methodology to the off-site construction field. Future research may be devoted to MiC transport scheduling under uncertainty. [ABSTRACT FROM AUTHOR]

Based on the view that community participation can be defined as the continuous trans-local mobility and localisation of not only organisations and individuals but also various nonhuman elements such as information and events, this paper explores how the community participation of Hong Kong in the conservation of Pokfulam Village is understood as socially extrospective and introspective processes. This paper is aimed to reveal how the knowledge of Treasure Hill in Taipei has been adapted (or not) to the community participation of Hong Kong's Pokfulam Village's heritage conservation. This provides insights into how the global flow of people, information, discourse, and technology has influenced the community participation in heritage conservation, especially across the Pacific Rim cities. Finally, the research discusses how local community can play a role in the dynamic local social structure of conserving their heritage, as well as 'whose heritage' in the mobility of global knowledge.

In the countryside, where intensive rural development and rising property values have been observed since the late 1970s, the preservation and meaning of traditional dwellings have emerged as crucial considerations in shaping Hong Kong's countryside conservation policy. The focus of this paper is on the conservation of temples, as we are drawn to these structures not only for their architectural merit but also for their role as public buildings within the countryside. Consequently, their cultural significance is heavily influenced by the stakeholders they are associated with, distinguishing them from other types of dwellings. This paper examines the coastal landscape of South Lantau, which includes several villages with distinct traditions that have undergone significant transformations since the 1960s. Located at the southwest edge of Hong Kong, Lantau Island had a rural lifestyle that was relatively undisturbed before WWII because of the difficulty in accessing the island. However, in response to the large people influx from China's mainland after 1949, the Hong Kong government introduced the Lantau Development Plan in 1953, mainly to open up new sources of freshwater resources for Hong Kong Island. The construction of South Lantau Road in 1955 and Shek Pik Reservoir in 1957 gradually led to the decline of agricultural activities in South Lantau and the population exodus of local villagers, resulting in a rupture to regional traditions. In multilineage communities such as the villages on South Lantau, worship of a common deity provides a vital source of social bonding, particularly for an area long beset by typhoons, piracy and banditry. Local people pray for safety and prosperity through collective rituals and celebratory activities. Therefore, temples are not only religious establishments but also embody the sense of social solidarity among villagers on South Lantau. Through the case study of three rural villages on South Lantau, this paper examines how temples play an important role in the continuity of the communal network amid repercussions from the postwar disruption of traditional rural life. Significantly, this pilot study also draws attention to the functions of temples in their historical context. It emphasises the importance of recognising and re-evaluating these buildings for cultural enhancement as part of community engagement. This study provides valuable insights for future conservation efforts for religious buildings in the countryside. [ABSTRACT FROM AUTHOR]

Rapid urbanization has resulted in the substantial population growth in metropolitan areas. However, existing research on population change of the cities predominantly draws on grid statistical data at the administrative level, overlooking the intra-urban variegation of population change. Particularly, there is a lack of attention given to the spatio-temporal change of population across different urban forms and functions. This paper therefore fills in the lacuna by clarifying the spatio-temporal characteristics of population growth in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) from 2000 to 2020 through the methods of local climate zone (LCZ) scheme and urban–rural gradients. The results showed that: (1) High population density was observed in the compact high-rise (LCZ 1) areas, with a noticeable decline along urban–rural gradients. (2) The city centers of GBA experienced the most significant population growth, while certain urban fringes and rural areas witnessed significant population shrinkage. (3) The rate of growth tended to slow down after 2010, but the uneven development of population-based urbanization was also noticeable, as urbanization and industrialization varied across different LCZ types and cities in GBA. This paper therefore contributes to a deeper understanding of population change and urbanization by clarifying their spatio-temporal contingences at landscape level. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic has exposed several chinks in the armour of public health infrastructure across the world. However, the impact of the pandemic has been assessed primarily from the perspective of the 'privileged' members of society. The experiences of the 'other' world inhabited by the marginalised communities, who have had their livelihoods crushed under the weight of the pandemic, have been scarcely documented. As thousands of migrant workers were more scared of death caused by hunger rather than the disease itself, the various steps taken by different countries to curb community transmission have unveiled the ugly side of these measures. For example, as several states such as the US, the UK, Singapore, Hong Kong, and India/Bharat imposed lockdowns, border closures, quarantines, inter alia, the most vulnerable section of the human population has been the migrant workers, especially those individuals who were employed in the unorganised sector. Thus, the global health crisis has unravelled deep-rooted deficiencies, racial biases, and an overall lack of concern and empathy for the lesser privileged, apart from the growing socio-economic divide between the rich and the poor. This research paper aims to explore the impact of the COVID-19 pandemic on migrant workers in the informal sector by exploring the measures imposed by the US, the UK, Singapore, Hong Kong, and India/Bharat and analyse how their fundamental rights, including the right to development, were compromised. Through this paper, the author provides a five-point strategic framework that can be adopted globally to prevent such instances in the future. [ABSTRACT FROM AUTHOR]

This paper contributes to the ongoing debate on the nature and characteristics of the volatility transmission channels of major crash events in international stock markets between 03 July 1997 and 09 March 2021. Using dynamic conditional correlations (DCC) for conditional correlations and volatility clustering, GARCH-BEKK for the direction of transmission of disturbances, and the Diebold-Yilmaz spillover index for the level of volatility contagion, the paper finds that the climbs in external shock transmissions have long-lasting impacts in domestic markets due to the contagion effect during crisis periods. The findings also reveal that the heavier magnitude of financial stress is transmitted between Asian countries via the Hong Kong stock market. Additionally, the degree of volatility spillovers between advanced and emerging equity markets is smaller compared to the pure spillovers between advanced markets or emerging markets, offering a window of opportunity for international market participants in terms of portfolio diversification and risk management applications. Furthermore, the study introduces a novel early warning system created by integrating DCC correlations with a state-of-the-art deep learning model to predict the global financial crisis and COVID-19 crisis. The experimental analysis of long short-term memory network finds evidence of contagion risk by verifying bursts in volatility spillovers and generating signals with high accuracy before the 12-month crisis period. This provides supplementary information that contributes to the decision-making process of practitioners, as well as offering indicative evidence that facilitates the assessment of market vulnerability for policymakers.

The informational domain related to COVID-19 reflects the degree of uncertainty and pace of evolution of the pandemic. This places a burden on peoples' searches for information to guide their choices, importantly including for COVID-19 vaccines. Thus, it is important for health communications that support vaccination campaigns to attenuate vaccine hesitancy to be accessible, including in terms of readability, and adapted to the evolving pandemic. This paper aims to understand internet searches on COVID-19 vaccination, specifically the mix of sources and readability of the sources over a two-year period (2021–2023) in Singapore, Hong Kong, and the Philippines, for search results in English, as English is a main language for each of these locations. The sources accessed through online searches in June 2021 and May 2023 were categorized by type of source and whether they were from one of the focal locations or elsewhere. The readability of information from web-search results was assessed using a set of readability tests (Flesch–Kincaid Reading Ease, Flesch–Kincaid Grade Level, Gunning Fog Index, Coleman–Liau Index, and Simple Measure of Gobbledygook Grade level). Over the two-year period there was an increase in government sources and reduction in mass media sources with distinct local patterns. Local government sources increased in Singapore whereas foreign government and multi-lateral organization sources increased in Hong Kong, with the Philippines being an intermediate pattern. In contrast to the changing mix of sources, the readability tests indicate a low proportion of URLs scoring within recommended readability thresholds across locations and types of sources over the two years. Information on COVID-19 vaccine development and deployment is an important part of health communications that includes internet search. The paper contributes to understanding health communications during a pandemic, including mix of local and non-local sources and contingency on local social and health context.

Qianhai—an innovation park in Shenzhen—has the possibility of boosting innovation in Hong Kong, Shenzhen and in the wider region. This paper reviews the existing evidence about which policies have promoted profitable innovation in the Qianhai region (Hong Kong and Shenzhen) in the past. We also point to the importance of profitable innovation—rather than just innovation for its own sake. Profits attract and keep firms in an international financial centre. Yet, until we know exactly how much profitability these innovative firms require and how to promote such profitability, the advice given in the literature to Qianhai's and other policymakers will remain woefully inadequate.

While public consultation is a signature process of democratic policy formulation, many governments manoeuvre to refract citizen's opinions or conduct it perfunctorily. Using the case of a medium of instruction policy in Hong Kong, this article unveils the strategies that the state and citizens employ to put their opinion through to the final policy text, during a public consultation process. Recent literature has identified the mechanisms through which individual actors or organisations contribute to broad policy agenda-setting or policy programme development. However, yet to be investigated is how they – sometimes with conflicting interests – collectively negotiate a policy with the state via public consultations. This paper investigates this very phenomenon, building on previous work conducted in the public policy field, analysing 51 government-generated documents through both thematic content analysis and critical discourse analysis. The paper uncovers four strategies adopted by administrations (non-commitment, case closure, disengagement for irrelevance, and placation) to evade citizens' equity-oriented demands and stakeholders' three counter strategies (mobilising other stakeholders into a coalition, reopening the case pointing out a new problem, and appealing by affirming relevance). The state's discrete refusals and stakeholders' conjoint reengagement tactics draw our attention to the complexity and subtlety involved in negotiation via public consultations.

This essay explores how and why protestors from the 2019 anti-ELAB (Extradition Law Amendment Bill) movement turned to popular Chinese religious practice for political dissent, and simultaneously tracks the negotiation of emerging sociocultural identities of Hong Kongers in the face of political upheaval. Attempting to pressure the Hong Kong Special Administrative Region government into meeting their demands, protestors adopted a wide range of tactics that brought protest activities to previously unaffected residential districts. Although no less hectic than other months during the movement, August 2019 also produced indelible moments of nonviolent innovation that attracted international media coverage. One of the protest events from this fertile period, the Hong Kong–wide Night Assemblies for Freeing Spirits, Almsgiving, Prayers for Merit, and Removal of Evil 全港超幽佈施祈褔除惡晚會, was held on August 9, 2019, in the districts of Wong Tai Sin and Shatin and specifically centered religious practice as a creative and potent source of political expression. To better understand this intersection of religion, politics, and identity in Hong Kong, this article analyzes protestors' ritual utterances and interview responses from the protest event's proceedings.

Elsewhere in this issue I state 'Chiropractic is the diagnosis and management of the neuromusculoskeletal system of the human body' and discuss the emergent problem of an increasing shrinkage of the constitutional framework of the discipline where current arguments continue to remove reference to subluxation from the profession's lexicon, even flagitiously mandating against teaching the idea within its natural context. In this editorial I give some examples of the good work being done to carry our profession to greatness, and balance that with some examples of wackiness from Canada and the United States of America, and once again from the usual dismal suspects in Europe. I am starting to think that Australia is one of the better places in the world to practice Conventional Chiropractic, yet offer caution that this may be about to change. Above all I hold that a Chiropractor carries spontaneous unspoken trust in what they see and feel, and conclude with a marvellous video of a Philosophy discussion about how strongly we can 'know things' from our patient's testimony.

This paper examines a new first-year EAP course in a Hong Kong university. It utilizes teacher and student reflections to understand the course's strengths and weaknesses, aiming to enhance its design and delivery. The study employed a qualitative approach whereby textual analysis was used to interpret the data collected in the form of written teacher reflections, written student reflections, and notes of teacher reflective dialogue. The thematic categories for coding the data were established based on the course's main learning outcomes: Effective Learning, Spoken Language, and Written Language. Findings reveal that teachers were more critical of the course compared to learners. Teachers expressed dissatisfaction with the pedagogical approach to Effective Learning unit, insufficient time provided in the course to teach solo speaking, and the inability to cover too many organizational and linguistic features in the writing unit. Students, however, did not have much to reflect on about Effective Learning, had mixed views about Spoken Language with some worried about reading from notes, and wrote extremely positively about their learning of Written Language. Nonetheless, their views provide valuable insights for course improvement. Consequently, the paper advocates for a reflective pedagogy approach to EAP that considers both teacher and student reflections to enhance teaching and learning outcomes. [ABSTRACT FROM AUTHOR]

Large-scale assessment of window views is demanded for precise housing valuation and quantified evidence for improving the built environment, especially in high-rise, high-density cities. However, the absence of a semantic segmentation dataset of window views forbids an accurate pixel-level assessment. This paper presents a City Information Model (CIM)-generated Window View (CIM-WV) dataset comprising 2,000 annotated images collected in the high-rise, high-density urban areas of Hong Kong. The CIM-WV includes seven semantic labels, i.e., building, sky, vegetation, road, waterbody, vehicle, and terrain. Experimental results of training a well-known deep learning (DL) model, DeepLab V3+ , on CIM-WV, achieved a high performance (per-class Intersection over Union (IoU) ≥ 86.23%) on segmenting major landscape elements, i.e., building, sky, vegetation, and waterbody, and consistently outperformed the transfer learning on a popular real-world street view dataset, Cityscapes. The DeepLab V3+ model trained on CIM-WV was robust (mIoU ≥ 72.09%) in Hong Kong Island and Kowloon Peninsula, and enhanced the semantic segmentation accuracy of real-world and Google Earth CIM-generated window view images. The contribution of this paper is three-fold. CIM-WV is the first public CIM-generated photorealistic window view dataset with rich semantics. Secondly, comparative analysis shows a more accurate window view assessment using DL from CIM-WV than deep transfer learning from ground-level views. Last, for urban researchers and practitioners, our publicly accessible DL models trained on CIM-WV enable novel multi-source window view-based urban applications including precise real estate valuation, improvement of built environment, and window view-related urban analytics.

This paper examines the role of standard block and modular dwelling designs in Hong Kong's public housing provision since the mid-1950s. It explores how standard types have evolved in relation to housing policies, demographic and socio-economic changes, and minimum space requirements. In contrast to other countries, Hong Kong lacks defined space or room standards. In the absence of space standards, Hong Kong relies on a living density standard. This paper studies the historical development of Hong Kong's public housing in terms of dwelling size as a measure of housing quality, questioning the effectiveness of standard block and dwelling designs as housing design controls and highlighting the contextual nature of dwelling usability and size. The analysis is based on public housing design projects, policies, and data implemented or presented by the Hong Kong government, particularly the Hong Kong Housing Authority. [ABSTRACT FROM AUTHOR]

Super Typhoon Saola (2309) skirted past south-southeast of Hong Kong within 40 km on the night of 1 September 2023, posing a significant storm surge threat to Hong Kong. Given the close proximity of Saola with a peak intensity of about 210 km/h within 300 km of Hong Kong, a close call of the "super typhoon direct-hit" scenario, this case provides valuable insights from a hindcast review of storm surge forecasts and warning operation using the Sea, Lake and Overland Surges from Hurricanes (SLOSH) model, which is the operational storm surge model adopted by the Hong Kong Observatory (HKO). The performance of the HKO's PRobabilistic Inundation Map Evaluation System (PRIMES) using both statistical and model ensemble approaches was also reviewed in this paper. Saola was a challenging case for operational forecasting of a compact TC structure with changes in storm size and intensity when it came close to Hong Kong. With major observations of storm structure using weather radar and dense automatic weather station, tide gauge and water level gauge networks, the high sensitivity of storm surge forecasts to the storm size parameter and the distance of closest approach was clearly revealed in the case of Saola. Even with a circularly symmetric TC parametric model like SLOSH, the hindcast review results illustrated that the model outputs were reasonably accurate during the closest approach of Saola given an accurate storm size and distance of closest approach were input, and using a highly computationally efficient storm surge model made it possible for the nowcasting of storm surges to handle compact and intense TC direct-hit cases in operational TC forecasting. Taking a nowcasting approach not only helps provide more reliable storm tide forecasts, but also facilitates the formulation of a better warning strategy when making final-call decisions in emergency response actions, based on the more frequent real-time analysis of TC position, intensity and storm size and the more accurate prediction of these parameters. A nowcasting workflow for storm surge operation was proposed in this paper. [ABSTRACT FROM AUTHOR]

Researchers' reflexivity usually focuses on the spatiality and sociality of their ethnographic fieldwork. As a result, the temporal context of their positionality, whereby their various identities interact with one another at different research phases, is often overlooked. This paper adopts an agentic intersectional approach and draws from our separate studies of Thai migrant women in Belgium and Hong Kong to unpack the temporality of the power dynamics between study participants and us (the researchers). Through this reflexive exercise, we identify three salient aspects: first, different identities of the researchers intersect at each phase of the study; second, researchers are dependent on gatekeepers and study participants, notably during the data-gathering phase; and third, the changing researcher–participant dynamics throughout the research process are embedded in broader relations of power that encompass social institutions and migrant/ethnic networks. Hence, researchers' self-discipline and constant awareness of positionality are of utmost importance for achieving well-situated knowledge (re)production. [ABSTRACT FROM AUTHOR]

'What do you do?' is a stereotypical networking question. How professionals answer acquaintancing questions like this when first meeting sheds light on how identity is construed. Using data from a naturally occurring networking event for elite professional services in Hong Kong, this paper uses a close study of interaction and follow-up interviews to identify and examine proximal networking mechanisms and processes. Consistently, participants used some amalgam of emblems, things that convey a social persona, from four different categories: industry (e.g., finance), professional role (e.g., FX trader), organizational affiliation (e.g., Morgan Stanley), and hierarchical position (e.g., associate). These generate evaluations of projected/absent instrumental gain, holistic eliteness, 'interestingness', and social proficiency (based on how they are deployed), resulting in symbolic capital transforming into (un)realized and projectible material outcomes. Theoretically, these findings contribute to our understanding of networking mechanisms. Practically, they can improve self-presentation, inform organizations of exclusionary effects, and enhance networking strategies. [ABSTRACT FROM AUTHOR]

Existing research on ethnic minority students in Hong Kong (HK) has documented their struggles in learning Chinese-as-an-Additional-Language (CAL) and the linguistic challenges for ethnic minority students to learn CAL at school can be the source of their anxiety, which may prevent them from integrating into HK society. The paper aims to explore ethnic minority students’ perceptions of how their Foreign Language Anxiety (FLA) affect their learning of CAL. The data, from semi-structured interviews with ethnic minority students of varying CAL anxiety levels and fieldnotes from classroom observations and informal teacher interviews, were analysed using Interpretative Phenomenological Analysis. The findings illustrate that while FLA can certainly influence students’ CAL learning experiences, other personal and sociocultural factors, such as students’ motivation to learn CAL, the prevalence of English-as-a-Lingua-Franca in society, and the impact of examination policies, also contribute significantly. This paper argued that the perceived relevance and importance of CAL in students’ lives are closely linked to FLA and can contribute to the lack of motivation observed in students with high or mid-level FLA. Thus, there is a need for teachers to attend to the interplay between other sociocultural factors and FLA when understanding ethnic minority students’ CAL learning behaviours. [ABSTRACT FROM AUTHOR]

Hotel booking websites to collect information about hospitality products/services are becoming more popular in the hotel industry. As a result, the importance of these websites for tourism firms marketing their services and products through electronic word of mouth (eWOM) on these hotel booking websites continues to grow. Despite its importance, there has been little research on how guests interact with information to increase eWOM. This paper creates a new scale for assessing guest interaction with Meituan.com information to fill this void. To this end, a three-step mixed-methods approach using open-ended surveys and published relevant research is used. Data were gathered from 440 hotel guests in Taiwan, China, and Hong Kong. Using SmartPLS 4, confirmatory factor analysis revealed 33 final items for the new scale. This paper significantly contributes to potential guest behavior by creating and confirming this new scale in the hospitality context. [ABSTRACT FROM AUTHOR]

In recent years, AI technologies have been developed to promote students' self‐regulated learning (SRL) and proactive learning in digital learning environments. This paper discusses a comparative study between generative AI‐based (SRLbot) and rule‐based AI chatbots (Nemobot) in a 3‐week science learning experience with 74 Secondary 4 students in Hong Kong. The experimental group used SRLbot to maintain a regular study habit and facilitate their SRL, while the control group utilized rule‐based AI chatbots. Results showed that SRLbot effectively enhanced students' science knowledge, behavioural engagement and motivation. Quantile regression analysis indicated that the number of interactions significantly predicted variations in SRL. Students appreciated the personalized recommendations and flexibility of SRLbot, which adjusted responses based on their specific learning and SRL scenarios. The ChatGPT‐enhanced instructional design reduced learning anxiety and promoted learning performance, motivation and sustained learning habits. Students' feedback on learning challenges, psychological support and self‐regulation behaviours provided insights into their progress and experience with this technology. SRLbot's adaptability and personalized approach distinguished it from rule‐based chatbots. The findings offer valuable evidence for AI developers and educators to consider generative AI settings and chatbot design, facilitating greater success in online science learning. Practitioner notesWhat is already known about this topic AI technologies have been used to support student self‐regulated learning (SRL) across subjects.SRL has been identified as an important aspect of student learning that can be developed through technological support.Generative AI technologies like ChatGPT have shown potential for enhancing student learning by providing personalized guidance and feedback.What this paper adds This paper reports on a case study that specifically examines the effectiveness of ChatGPT in promoting SRL among secondary students.The study provides evidence that ChatGPT can enhance students' science knowledge, motivation and SRL compared to a rule‐based AI chatbot.The study offers insights into how ChatGPT can be used as a tool to facilitate SRL and promote sustained learning habits.Implications for practice and/or policy The findings of this study suggest that educators should consider the potential of ChatGPT and other generative AI technologies to support student learning and SRL.Educators and students should be aware of the limitations of AI technologies and ensure that they are used appropriately to generate desired responses.It is also important to equip teachers and students with AI competencies to enable them to use AI for learning and teaching.

Purpose: This paper investigates how individuals' decision-making approach and perceptions of a game's cognitive realism affect the performance of virtual businesses in a web-based simulation game. Design/methodology/approach: Survey data are collected from 274 business simulation game users and is analysed using the fsQCA technique. Findings: The study identifies three alternative pathways to high and low performance in a business simulation game. Results indicate that a flexible decision-making approach exists in all high performance pathway solutions. Where a game is perceived to be realistic, a more focused decision-making approach is associated with high performance. However, where perceived cognitive realism is absent, a less focused experimental decision-making approach is employed, which increases the chances to achieve low performance. Finally, perceived cognitive realism and an experimental decision-making approach are found to be mutually exclusive for achieving high performance. Originality/value: Whilst the learning benefits of web-based simulation games are widely acknowledged, the complex interplay amongst factors affecting performance in games is under-researched. Limited research exists on how perceptions of a game's cognitive realism interact with user decision-making approaches to affect performance. [ABSTRACT FROM AUTHOR]

Caught between its Chinese and British colonial history, Hong Kong’s path to self-actualization is unsure without preserving its tangible and intangible heritage. This paper examines the region’s several layers of heritage through the movement to preserve the Star and the Queen piers in 2007, using two theoretical frameworks, Abbas’ culture of disappearance and Tunbridge’s dissonant heritage. Despite the piers’ demolition, their role is vital in understanding conflicting histories and decolonizing the region’s identity. [ABSTRACT FROM AUTHOR]

The pursuit of equitable education is key to a government's regulation and allocation of lifechances, which enables social integration. Yet, evidence of the diminishing returns of degrees and of the "skills mismatch" between higher education training and labour market requirements casts doubts on the role of higher educational institutions in facilitating social mobility. This paper draws upon the findings of 40 qualitative interviews with young people conducted in 2018 in Hong Kong to shed light on the micro-level processes in which higher education training is translated into graduate employment outcomes. Findings comparing two sets of higher education graduates' interview narratives are presented. Assumptions of the logic of human capital theory are questioned from the "positional" and the "processual" perspectives on graduate employability. The discussion unpacks the meanings of "skills mismatch" and "graduate employability," and foregrounds the assumptions of the differential values assigned to skills and knowledges of different kinds in the local higher education system. With the insights drawn, this paper concludes with a reflection on the relevance of higher education to our understanding of social mobility and social integration in post-Covid-19 Hong Kong.

This paper investigates problems of space in Hong Kong kindergartens. It reports survey findings of a policy study relating to the Kindergarten Education Scheme (KES). KES emphasizes holistic development and child-centred pedagogy, which require larger and more flexible spaces than traditional desk-based learning. The study aimed to explore kindergartens' responses to the resulting challenges around providing adequate space within Hong Kong's high density urban environment. Questionnaires were sent to principals of 751 KES kindergartens. 325 valid questionnaires were collected (response rate: 43.5%). Analysis comprised descriptive statistics, inferential tests of relationships between operation mode and other variables, and coding of open-ended question responses. The paper highlights three key findings: (i) kindergartens reported a wide range of challenges relating to space; (ii) most augment their provision by using public spaces outside the premises, but these spaces come with their own challenges; and (iii) there were significant differences in the extent of reported problems between kindergartens operating in different modes, with long-whole-day kindergartens experiencing greater difficulty and disparity. Situating these findings in the historical context of Hong Kong's uneven urban development, we argue that policy improvement of spatial provision will require reducing pressures on kindergarten spaces, rather than merely setting out spatial standards.

Background: Given students' lack of self‐directed learning skills and the growing concern about implementing massive online open courses (MOOCs) in K12 education, learning strategies are needed to facilitate MOOC learning. Many studies have provided different strategies for effective learning in MOOCs. However, there is still limited research to confirm whether these strategies effectively support MOOC learning when deployed by secondary schools, which are not MOOC developers. Objectives: This mixed‐method study examines the provision of different learning strategies, including a learning guide, an academic mentoring programme, a training workshop, and a reimbursement scheme, and investigates the impact of these strategies on student learning in MOOCs. Methods: The study uses two data sources: (1) surveys with 40 participants and (2) semi‐structured interviews with 12 participants. The quantitative data were analysed with descriptive statistics and Fisher's exact test, and the qualitative data were analysed with thematic analysis. Results and Conclusion: The findings indicate that MOOC learners had positive attitudes towards the overall school support, with mentoring enjoying great popularity amongst the students. In terms of the effectiveness of the school support, the mentoring programme and reimbursement scheme were more effective than the university training and learning guide. The paper discusses the implications for researchers and educators. Lay Description: What is already known about this topic: There are a large number of K12 MOOC implementations, which are (i) STEM‐related and computer science courses, and (ii) from Europe and the USA.Limited studies provided different learning strategies for MOOC learning from the perspective of K12 schools, which are not MOOC developers.There is a need to explore MOOC initiatives encompassing a wide variety of subjects, including computer science MOOCs and non‐computer science MOOCs, in regions beyond Europe and the USA.There is also a need for further scrutiny of the effectiveness of learning strategies provided by the K12 school. What this paper adds: Our study launched the first MOOC implementation in K12, encompassing several subject areas beyond computer science in the region of Asia.Our study provided different learning strategies adopted by the K12 school, and the analysis revealed that MOOC learners took positive attitudes towards overall school support with mentoring enjoying great popularity with these students.Our study examined the effectiveness of school support and identified that mentoring and reimbursement are more effective than university training and the learning guide. Implications for practitioners: The insights gained from the study enable other K12 schools and educators to implement MOOC into existing school infrastructures successfully.These strategies provided in the MOOC implementation program can be helpful in many different online learning contexts.

Purpose: This research aims to understand employers' views and preferences on the assessment of holistic competencies (HCs) in graduates, a topic with existing gaps in literature. With the disparities between higher education practices and employer expectations concerning HC assessment, the study focuses on what employers wish to see in graduates' resumes. As resumes play a pivotal role in recruitment, influencing who gets shortlisted, this research seeks to discern how graduates can optimally make a good first impression. In essence, the study endeavours to enhance knowledge on employers' inferences about a candidate's HCs and employability skills based on resume content. Design/methodology/approach: A comprehensive 12-item survey was devised to collect employers' perceptions and expectations of holistic competencies (HCs) assessment. The survey was informed by a synthesis of discussions with employers, teachers and a critical review paper. It aimed to understand employers' HC assessment expectations and bridge the teachers' understanding gap of students' HC achievements. Questions included demographic data, and specifics about employers' perceptions of graduates' resumes. The survey was hosted on Qualtrics and disseminated via the authors' networks, social media and university departments in Hong Kong, with responses gathered from April to June 2021. Findings: This study reveals that employers value holistic competencies (HCs), especially those developed through work placements and extracurricular activities, as indicators of job readiness in graduates. It is imperative for students to highlight these competencies in their resumes, potentially also demonstrating them through digital portfolios. The research underscores the need for higher education institutions to systematically document and report students' HC attainments. They can support students by informing them about employer expectations, offering writing workshops and resume samples. Integrating experience-based opportunities into the curriculum can also enhance HC development, preparing students for job market competitiveness and readiness. Research limitations/implications: The research limitations include the lack of a widely accepted, standardized method to document and evidence students' holistic competencies (HCs). The implications, however, stress the necessity for students to effectively communicate their HCs to employers, requiring awareness of expectations and adaptability to evolving technologies. Educators and higher education institutions must provide resources and opportunities to students to develop, demonstrate and document these HCs. In the absence of a standardised method for HC reporting, alternative solutions like e-portfolios and platforms like YOCLE can help students gather feedback and present evidence of competencies to prospective employers. Practical implications: The study's practical implications revolve around enhancing job readiness in graduates. Universities need to bolster their support, helping students understand employer expectations, offering writing workshops, resume templates and resources. Incorporation of platforms like YOCLE can help gather and retain evaluations, while promoting internships and extracurricular activities enhances HC development. Graduates must include work experiences, HC achievements and extracurricular activities in their resumes, even exploring digital portfolios for broader evidence presentation. They should also prepare for digital interactions like Zoom calls or video resumes, adapting to the technological advancements propelled by recent global disruptions. Originality/value: This research provides original insights into employer preferences regarding job candidates' holistic competencies (HCs) in resumes, an area not deeply explored in past literature. Focusing on how resumes can best demonstrate HC attainments, it offers practical guidance for higher education institutions preparing students for the job market. Although the study's scope is limited by geographical and industry-specific sampling, it provides a foundational understanding of employers' recruitment expectations influenced by resumes. Its value lies in its potential to spur further research into varying contexts and industries, leading to broader implications for graduate employability and resume building practices worldwide.

This paper takes the freezing project of the North Arch Tunnel of the Hong Kong–Zhuhai–Macao Bridge as an example. Based on Darcy's law and the theory of heat transfer in porous media, using the coupled module of the temperature field and seepage field in the COMSOL Multiphysics software, numerical simulations of the freezing reinforcement of the new pipe curtain freezing method are conducted to study the influence of different factors on this method under seepage conditions. The research shows that an increase in the groundwater flow velocity will affect the development of frozen soil curtains, prolonging the formation time of frozen soil curtains. A rise in the initial ground temperature will increase the time required for the formation of frozen soil curtains during the freezing process, resulting in a slight increase in the temperature of the final frozen soil curtains. With an increase in the salinity of the groundwater, the temperature at the temperature measurement point upstream of the freezing pipe increases, while the temperature at the temperature measurement point downstream of the freezing pipe decreases. The average temperature of the frozen soil curtain also increases with an increase in the salinity of the groundwater. This study is expected to provide a valuable reference for similar projects in the future. [ABSTRACT FROM AUTHOR]

A novel insulated gate bipolar transistor with Semi-Insulated POly Silicon (SIPOS) is presented in this paper and analyzed through TCAD simulation. In the off state, the SIPOS-IGBT can obtain a uniform electric field distribution, which enables a thinner drift region under the same breakdown voltage. In the on state, an electron accumulation layer is formed along the SIPOS, which can increase the injection level of the "PiN region" in the device, and the carrier concentration in the drift region is also increased due to the charge balance effect. Moreover, the SIPOS-IGBT can achieve a quick and thorough depletion in the drift region during the turn-off transient, which can greatly reduce the turn-off loss of the SIPOS-IGBT. These advantages improve the tradeoff between the conduction and switching losses. According to the simulation results, the SIPOS-IGBT obtained a 58% lower turn loss than that of a field-stop (FS) IGBT and 30% lower than an HK-IGBT with the same on-state voltage.

Slot allocation in a single airport aims to maximize the utilization of airport-declared capacity under operational and regulation constraints, while that in a multi-airport system (MAS) has to take airspace capacity into account. This is due to the fact that the conflict of using the limited capacity of certain departure/arrival fixes in the terminal airspace could induce unnecessary flight delays. The uncertainty of flying times between the airport and congested fixes makes it even more complicated for slot allocation in a MAS. Traffic flow may exceed capacity when the flying times of flights change. In this paper, the authors propose an uncertainty slot allocation model for a MAS (USAM). The objective of the model is to minimize the total displacement of slot requests in the MAS while considering all of the capacity constraints, as well as the uncertainty of flying time. The constraints of departure/arrival fixes are formulated as chance constraints, and then the Lyapunov theorem is applied for reformulation. The USAM is applied in the MAS of the Guangdong-Hong Kong-Macao Greater Bay Area (GBA). Specifically, the impact of the uncertainty of flying times from five airports to airspace fix YIN is investigated. Results show that the total displacement would increase if the uncertainty of flying time was considered. The optimized schedule using the USAM, however, is more robust and can satisfy capacity constraints under various scenarios. [ABSTRACT FROM AUTHOR]

Insurance premium trust is a hybrid model that combines insurance and trust services. In recent years, with the gradual improvement of China's economy, there has been a heightened awareness of wealth management among people. To meet this growing demand, the insurance market has expanded greatly, resulting in the emergence of various new insurance products, including insurance premium trust products. Based on the status of the domestic insurance market and Hong Kong insurance market in recent years, this paper summarizes the advantages and disadvantages of insurance premium trust products launched by the Hong Kong insurance industry. Furthermore, it discusses the prospects and development of the Hong Kong insurance premium trust model against the background of the establishment of the Guangdong-Hong Kong-Macao Greater Bay Area (GBA).

Because of a growing population and shrinking arable land, the world is facing a global food crisis. One important solution could be to subsidize farmers to sustain their production so that they can produce more food for consumers and earn more money for themselves. An efficient subsidy program should also aim to reduce income inequality among farmers, as measured by the Gini coefficient of farmers' income. In this paper, we examine and compare the effects of input and output farm subsidy programs. The input subsidy reduces the farmers' input purchasing costs, whereas the output subsidy reduces the farmers' output processing costs. By considering a continuum of infinitesimal price-taking farmers who are heterogeneous in their average yield rates, our equilibrium analysis of a game-theoretical model yields three results. First, both subsidy schemes reduce the aggregate income inequality measured by the Gini coefficient. However, they create the following "opposite" effects: the input subsidy decreases the income gap among farmers (under mild conditions), whereas the output subsidy increases it. Second, farmers with low yield rates prefer the input subsidy, whereas farmers with high yield rates prefer the output subsidy. Third, the output subsidy scheme is more effective in improving the total farmer income than the input subsidy scheme, whereas the input subsidy scheme is more effective in reducing income disparities and improving consumer surplus than the output subsidy scheme. Our results provide new insights for policymakers who are crafting subsidy schemes. This paper was accepted by Jayashankar Swaminathan, operations management.

This paper studies a dynamic principal–agent setting in which the principal needs to dynamically schedule an agent to work or be suspended. When the agent is directed to work and exert effort, the arrival rate of a Poisson process is increased, which increases the principal's payoff. Suspension, on the other hand, serves as a threat to the agent by delaying future payments. A key feature of our setting is a switching cost whenever the suspension stops and the work starts again. We formulate the problem as an optimal control model with switching and fully characterize the optimal control policies/contract structures under different parameter settings. Our analysis shows that, when the switching cost is not too high, the optimal contract demonstrates a generalized control-band structure. The length of each suspension episode, on the other hand, is fixed. Overall, the optimal contract is easy to describe, compute, and implement.

This paper is based on findings of a study that examined challenges to innovation and the greening of economies identified by businesses, TVET institutions, and other organisations with the aim to formulate options for strategic actions to increase 'sustainable competitiveness' of Hong Kong SAR, China as measured by The Global Sustainable Competitiveness Index (GSCI). This article focuses on Hong Kong but refers to Denmark (one of the Nordic countries participated in the study) as it scores much higher than China on the GSCI. The assumption of this study is that Denmark's experience can help formulate policies and the strategic actions required for building sustainable development (SD) solutions for economic green growth through innovation and skills development in Hong Kong. The study used a qualitative methodology. Data was collected through desk-top research and interviews with stakeholders from both settings. The results identified a clear distinction between innovation and greening in terms of education and skills, the business sectors involved, support modalities (policies), investment, as well as culture in both Denmark and Hong Kong SAR. Despite the very different approaches to innovation and variations in both industry structure and the environment for training and skills development, the challenges to industry and their implications for TVET in terms of greening and innovation were found to be very similar in the two contexts. Thus, contrary to the study's assumptions, this article discusses the similar policy responses to these 'green' challenges for both contexts, as well as recommended policy goals and strategic actions with implications for TVET that can support green innovation in both settings.

As one of the four major bay areas in the world, the Guangdong–Hong Kong–Macao Greater Bay Area (GBA) is a highly integrated mega urban agglomeration and its unparalleled urbanization has induced prominent land contradictions between humans and nature, which hinders its sustainability and has become the primary concern in this region. In this paper, we probed the historical characteristics of land use and land cover change (LUCC) in the GBA from 2005 to 2015, and forecasted its future land use pattern for 2030, 2050, and 2070, using a cellular automata–Markov (CA–Markov) model, under three typical tailored scenarios, i.e., urban development (UD), cropland protection (CP), and ecology security (ES), for land use optimization. The major findings are as follows: (1) The encroachments of build-up land on the other land uses under rapid urbanization accounted for the leading forces of LUCCs in the past decade. Accordingly, the urban sprawl was up to 1441.73 km2 (23.47%), with cropland, forest land, and water areas reduced by 570.77 km2 (4.38%), 526.05 km2 (1.76%), and 429.89 km2 (10.88%), respectively. (2) Based on the validated CA–Markov model, significant differences are found in future land use patterns under multiple scenarios, with the discrepancy magnified over time and driven by different orientations. (3) Through comprehensive comparisons and tradeoffs, the ES scenario mode seems optimal for the GBA in the next decades, which optimizes the balance between socio-economic development and ecological protection. These results serve as an early warning for future land problems and can be applied to land use management and policy formulation to promote the sustainable development of the GBA.

Chlorophyll-a (Chl-a) concentration monitoring is very important for managing water resources and ensuring the stability of marine ecosystems. Due to their high operating efficiency and high prediction accuracy, backpropagation (BP) neural networks are widely used in Chl-a concentration inversion. However, BP neural networks tend to become stuck in local optima, and their prediction accuracy fluctuates significantly, thus posing restrictions to their accuracy and stability in the inversion process. Studies have found that metaheuristic optimization algorithms can significantly improve these shortcomings by optimizing the initial parameters (weights and biases) of BP neural networks. In this paper, the adaptive nonlinear weight coefficient, the path search strategy "Levy flight" and the dynamic crossover mechanism are introduced to optimize the three main steps of the Artificial Ecosystem Optimization (AEO) algorithm to overcome the algorithm's limitation in solving complex problems, improve its global search capability, and thereby improve its performance in optimizing BP neural networks. Relying on Google Earth Engine and Google Colaboratory (Colab), a model for the inversion of Chl-a concentration in the coastal waters of Hong Kong was built to verify the performance of the improved AEO algorithm in optimizing BP neural networks, and the improved AEO algorithm proposed herein was compared with 17 different metaheuristic optimization algorithms. The results show that the Chl-a concentration inversion model based on a BP neural network optimized using the improved AEO algorithm is significantly superior to other models in terms of prediction accuracy and stability, and the results obtained via the model through inversion with respect to Chl-a concentration in the coastal waters of Hong Kong during heavy precipitation events and red tides are highly consistent with the measured values of Chl-a concentration in both time and space domains. These conclusions can provide a new method for Chl-a concentration monitoring and water quality management for coastal waters. [ABSTRACT FROM AUTHOR]

Background: Health communication in the COVID-19 pandemic can be effectively implemented if all members of the populations, including marginalized population such as migrant domestic workers (MDWs), have good eHealth literacy. Lessons learned during this critical period may help improve planning and mitigation of the impacts of future health crises. Methods: This study aimed to examine and explore the eHealth literacy levels of the MDWs in Hong Kong during the COVID-19 pandemic by using a convergent mixed methods research design. A total of 1156 Hong Kong MDWs participated in a paper-based survey using a multistage cluster random sampling design for the quantitative component. eHealth literacy was measured using an eHealth literacy Scale (eHEALS). For the qualitative component, a purposive sampling of 19 MDWs participated in face-to-face, semi-structured, in-depth interviews. Descriptive statistics and multiple regression analyses were used to carry out the quantitative analysis, while thematic analysis was used for the qualitative analysis. Both quantitative and qualitative data were merged and integrated for mixed-methods analysis. Results: The meta-inferences of the quantitative and qualitative results mainly confirmed that MDWs in Hong Kong had good levels of eHealth literacy. The use of Instagram, YouTube and WhatsApp as the COVID-19 information sources, in addition to having an interest in the topic of the current spread of COVID-19 together with the Hong Kong government's policies related to COVID-19, were found to be associated with eHealth literacy. Conclusions: The eHealth literacy level of MDWs in Hong Kong was shown to be good and it was influenced by the use of popular social media platforms including Instagram, YouTube, and WhatsApp. It is realistic to suggest that such platforms should be harnessed for health communication during the pandemic. Yet, regulations to combat false information on these media are also urgently needed. [ABSTRACT FROM AUTHOR]
