This paper explores the "sporadic hyper-precarity" encountered by migrant domestic workers in Hong Kong when the city was hit by the Omicron outbreaks in early 2022. Migrant workers have long been suffering from job insecurity and structural vulnerability due to the contractization and flexibilization of work. The paper discusses how this structural vulnerability came to intersect with the health risks induced by the COVID pandemic. Adding to the debates of the structural precarity characterizing migrant work, we will further interrogate how workers are also susceptible to "sporadic hyper-precarity" – the kind of sporadic risks, uncertainty, vulnerabilities and stigmatization at times of crisis. The paper will elaborate on the "sanitized divide" and "care divide" between local families and domestic workers that has resulted in the unequal treatment of workers. [ABSTRACT FROM AUTHOR]

East Asian urbanization is characterized by complex processes of extensive densification. Fuelled by rapid economic growth, Asian cities’ size, scale, and physical dimensions remain incomparable to any Western setting. During the past thirty years alone, various concepts have attempted to define hyperdensity, layering, and intensity as core principles of Asian urban development. Although these concepts explore the physical properties of development, few examples provide insights into the behavioural and social dimensions of such complex morphological settings. This paper examines the effects of urban compaction and volumetric urbanism on liveability in East Asian cities. Hong Kong exemplifies an extreme scale and rate of densification. Podium developments – commercial plinths elevated above street level that connect large residential towers to commercial complexes – are one of the city’s most common development types. The hypothesis is that the combination of different types of podium development results in the interiorization of the urban realm, which compresses public services, social engagements, and behavioural conditions into diverse privatized and fragmented ‘public interiors’. To explore these conditions, this paper first outlines the conceptual premise of reading urban sett ings through the lens of volumetric urban compaction. This framework combines urban compaction and volumetric urbanism. Second, the paper discusses theories that deal with the links between spatial settings and behavioural traits. Privatization is of particular interest here, including those processes in which the private and the public become interchangeable conditions or where the temporary occupation of functions occurs. The different concepts – volumetric urban compaction and interiority – are studied within Olympian City, a podium development in Kowloon (Hong Kong). Through fieldwork, the case is investigated in terms of the elements that make up Olympian City’s spatial configuration and how different groups use space at different times of the day and week. The case study shows that Hong Kong’s development follows an economically driven model of volumetric urban compaction; it supports a larger privatization strategy that depends on the interiorization of the city to the extent that makes the overall structure highly exclusive, static, and controlled.

Borrower hardship, while a critical issue, is not often addressed by consumer protection frameworks across the Asia–Pacific. The widespread use of payment holidays during the COVID-19 crisis provides a significant case study on the importance of having borrower hardship provisions as a consumer protection tool. This paper compares the pre-pandemic availability of payment holidays in three Asia–Pacific jurisdictions: Australia, Singapore, and Hong Kong. It evaluates their existing legislative frameworks, as well as regulatory and industry guidelines on borrower hardship, and contrasts this with their use of payment holidays during the pandemic. Where there were existing industry guidelines on borrower hardship, lenders were able to spearhead an industry-wide approach towards payment relief without regulatory intervention by governments. Beyond the pandemic, the paper argues that self-regulation has potential for protecting borrower interests by standardising the scope of, and the procedure for, obtaining hardship relief. It argues that there is a need for a greater prevalence of industry codes of conducts governing lenders' approach towards borrower hardship across the Asia–Pacific. [ABSTRACT FROM AUTHOR]

There has been much confusion in property rights inquiry into real (immovable) property (i.e., land) between open access and common property, and between public property and common property because that is often also open access. This paper argues that the property rights and access control are two distinct dimensions of land resource management. Access control involves the exercise of exclusionary power relevant to the management of the immovable property (property management) for its optimal use. A review of the literature shows that definitions of property management tend to be too narrow but point towards the need to articulate issues within the property rights paradigm. As a contribution to sustainable resource use as a dimension of land planning, this paper points out and discusses the probable sources of the confusion between land property rights and property management. A "Land Property Rights and Management Matrix" (LPRMM) is developed as a theoretical tool for clarifying the confusion and the relationships amongst relevant concepts. The LPRMM is theoretically informed by Barzel's not entirely correct distinction between legal (de jure) and economic (de facto) rights and enriched by relevant literature on property rights and property management. Practical use of the LPRMM is illustrated by its application to analyze the issues pertaining to the actual resource-use phenomena in colonial military buildings erected on both private and public land in Hong Kong. The results show that heritage buildings on land under public ownership as private property can be neglected or intensively managed. The LPRMM is not only a useful theoretical tool for precisely assessing the actual affairs of resource use but also a practical tool for identifying issues of property management in its widest sense. The LPRMM offered is a proper interpretation of Barzel's distinction between legal and economic rights and contributes to systematically re-interpreting property management as town planning writ large in terms of de jure property rights and de facto access.

Purpose: This paper aims to make a systematic review of the manpower prediction model of the construction industry. It aims to determine the forecasting model's development trend, analyse the use limitations and applicable conditions of each forecasting model and then identify the impact indicators of the human resource forecasting model from an economic point of view. It is hoped that this study will provide insights into the selection of forecasting models for governments and groups that are dealing with human resource forecasts. Design/methodology/approach: The common search engine, Scopus, was used to retrieve construction manpower forecast-related articles for this review. Keywords such as "construction", "building", "labour", "manpower" were searched. Papers that not related to the manpower prediction model of the construction industry were excluded. A total of 27 articles were obtained and rated according to the publication time, author and organisation of the article. The prediction model used in the selected paper was analysed. Findings: The number of papers focussing on the prediction of manpower in the construction industry is on the rise. Hong Kong is the region with the largest number of published papers. Different methods have different requirements for the quality of historical data. Most forecasting methods are not suitable for sudden changes in the labour market. This paper also finds that the construction output is the economic indicator with the most significant influence on the forecasting model. Research limitations/implications: The research results discuss the problem that the prediction results are not accurate due to the sudden change of data in the current prediction model. Besides, the study results take stock of the published literature and can provide an overall understanding of the forecasting methods of human resources in the construction industry. Practical implications: Through this study, decision-makers can choose a reasonable prediction model according to their situation. Decision-makers can make clear plans for future construction projects specifically when there are changes in the labour market caused by emergencies. Also, this study can help decision-makers understand the current research trend of human resources forecasting models. Originality/value: Although the human resource prediction model's effectiveness in the construction industry is affected by the dynamic change of data, the research results show that it is expected to solve the problem using artificial intelligence. No one has researched this area, and it is expected to become the focus of research in the future. [ABSTRACT FROM AUTHOR]

To mitigate the climate change issue, the Government of the Hong Kong Special Administrative Region (HKSAR) proposed the "Hong Kong Climate Change Plan 2030+" with an ambitious goal of reducing the carbon intensity to 65%–70% below 2005 levels by 2030. To achieve this target, the HKSAR Government has developed two District Cooling Systems (DCS) to promote the use of district energy system, enhancing the overall energy efficiency for cooling purpose. One of the government-owned DCSs is located at the Hong Kong-Zhuhai-Macao Bridge Hong Kong Port (HZMB-HKP), producing a total design cooling capacity of 24.16 MW to passenger clearance building and ancillary buildings there. This paper demonstrates how the DCS at HZMB-HKP could enhance overall energy efficiency for cooling purpose, through proper chiller sequencing control, and reduce CO2 emission significantly. An optimal seasonal chiller operation mode is also suggested to be adopted at the DCS at HZMB-HKP from cost-effectiveness perspective. Practical application: District Cooling Systems are considered as a promising solution to alleviate the climate change issue. An optimized chiller sequencing control strategy of DCS can effectively reduce overall cooling energy consumption, so as to achieve carbon neutrality. This paper outlines a case study on a cost-effective operational control strategy of the DCS at HZMB-HKP. The analysis of both the theoretical and practical sequencing control strategy can be taken as a reference for DCS development in the future. [ABSTRACT FROM AUTHOR]

In response to the COVID-19 pandemic, modular construction has been adopted for rapidly delivering healthcare facilities, but few have systematically explored the impacts of the pandemic and the contributions of modular construction. This paper aims to evaluate modular construction for delivering healthcare facilities in response to COVID-19, through the exploration of the challenges, strategies, and performance of using modular construction for emergency healthcare building project delivery. The study was conducted using 12 real-life healthcare building projects in Hong Kong with both within- and cross-case analyses. The results of the within-case study reveal critical challenges such as tight program but limited resources available and the corresponding strategies such as implementation of smart technologies. The results of the cross-case analysis indicate 106% improved time efficiency and 203% enhanced cost efficiency of using modular construction compared with conventional practices. Based on the multi-case studies, the paper develops an innovative framework which illustrates the roles of stakeholders, goals, engineering challenges, and management principles of using modular construction. Practically, the paper should assist both policymakers and industry stakeholders in addressing the critical challenges of delivering healthcare facilities under COVID-19 in an efficient and collaborative manner. Theoretically, it should set an exemplar of linking the building construction industry with emergency management and healthcare service systems to facilitate efficient response to pandemics.

The outline of the development plan issued by CPC Central Committee and the State Council for the Guangdong Hong Kong Macao Bay Area clearly pointed out that the Guangdong-Hong Kong-Macao Bay Area should be built into a vibrant world-class urban agglomeration, an international science and technology innovation center, an important support for the construction of the "the Belt and Road," and a demonstration area for in-depth cooperation between the mainland and Hong Kong and Macao; and a high-quality life circle suitable for living, working, and traveling should be created to become a model of high-quality sustainable development. In order to develop the Guangdong-Hong Kong-Macao Bay Area, it is extremely important to enhance the regional business environment. This paper focuses on five influencing factors: policy support, talent guarantee, market supervision, financial support, and cultural promotion. Based on one-way ANOVA and Cobb Douglas function, this paper makes an empirical study on the two important node cities of Zhuhai and Macao. The results show that (1) different factors have different degrees of significant impact on the regional business environment, among which the industry type has the greatest impact, and the duration of enterprise registration has the least impact; (2) when the factors act alone, there is a significant positive correlation between the evaluation dimensions, but most of the correlation degrees are not much different. Finance and talents are the weaknesses of the business environment in the two cities. (3) When the factors are combined, different factors have significant differences in different regions. Zhuhai mainly benefits from policy support, while Macao mainly benefits from market supervision. (4) Regional integration can produce significant association relationship, among which cultural promotion is an important factor. These five important factors have been effectively identified, which have played a leading role in the further design and development direction of the Guangdong-Hong Kong-Macao Bay Area in the future and have an extremely important enlightenment for the study of the business environment in this region.

Tens of thousands of children living on Mainland China cross the border between Shenzhen and Hong Kong for a 'better education' every day. A well-oiled industry is in place to manage, facilitate and control this education mobility field. It involves schools, diverse businesses and nongovernmental organisations that, in articulation with the Chinese and Hong Kong states, stimulate and regulate the movement of people, materialities, ideas and practices. Drawing on our fieldwork and media analysis, this paper unpacks the transurban mobility industry to illustrate the role of the various players and how they work in conjunction to facilitate cross-border schooling, especially among the very young children. We map out and visualise with photos the workings of the schools, buses, escorts, tutoring centres, day care and boarding houses. We show how the mobility industry, intersecting with other business networks and mobility systems, links Shenzhen and Hong Kong, taking and making places in these cities, especially in the border region. Our paper illustrates the role of this mobility industry in the making of the political-economy and socio-culture of the border area, which constantly connects, divides and redefines the two cities and regions it bridges. We end with some reflections on the implications of the recent political challenges and COVID-I9 pandemic on this cross-border education mobility system. [ABSTRACT FROM AUTHOR]

International students are a critical source of income for UK universities, and yet reports indicate that their numbers have been in decline since academic year 2010-2011. Consequently, UK universities need to work harder to attract international students than ever before. This paper uses qualitative interviews with international office staff based at UK higher education institutions together with observational research at recruitment events which took place in Hong Kong in 20l7 to demonstrate how the urban has a critical role to play in the international student migration industry. The paper showcases three urban encounters in the recruitment process: the higher education recruitment fair; the connections universities draw between themselves and other urban locations; and by considering how predeparture events mobilise the urban landscape to communicate dynamic learning experiences. The retelling and analysis of these encounters demonstrate how universities, and the UK, create, foster and embed the geographical imaginary in their recruitment processes in order to entice and encourage brand loyalty from prospective students.

This paper examines how family atmosphere, parental self-efficacy, parenting methods and children's patterns of mobile device use result in negative outcomes for children's use of mobile devices. The hierarchical multiple regression analysis found that a stressful and conflictive family atmosphere and higher dependence on mobile devices promote negative outcomes. The self-efficacy of parents in helping their children to avoid the negative outcomes was also found to be positive associated the actual negative outcomes that their children had experienced in using mobile devices. Data were collected from a sample of 1561 students from 39 secondary schools in Hong Kong, including students studying at the Form one to Form five levels (equivalent to the seventh to eighth grade) and 1233 of their parents. Hierarchical linear regression analysis was applied to examine the magnitude of the associations between these variables. The paper highlights the importance of avoiding a tense atmosphere and conflicts between parents and children. For service providers, this paper provides a comprehensive reference to understand how parents and children think about family dynamics and relationships under the impact of technological development on individual families. Also, parents would be more advantageous if they were more efficacious about themselves in helping children to avoid the negative outcomes. This study can help service providers determine which intervention approaches can effectively support families in managing parent–child conflicts, developing cohesiveness, and facilitating children's proper use of new technologies.

Much recent work on transport and the economy has focused on 'Wider Economic Impacts' (WEIs) of infrastructure investment, the impacts other than time savings benefiting those actually using the transport network. Differential effects of transportation infrastructure by mode such as urban rail and road are relatively well known. However, impacts of other mode such as walking are scarce. This paper estimates wider economic impacts related to productivity from full rail, road and walking transport networks in Hong Kong in 2016. To the best of our knowledge, this is the first paper that makes use of complex network science indicators with spatial cognition-weighted accessibility combining full urban rail network, road network, and pedestrian network in capturing wider economic impacts. We use an instrumental variable approach to identify the causal effect of transport network centralities on productivity measured by gross value added. Our identification strategy largely relies on the exogenous variations from historical planned and existing transport networks. A first specification confirms the significance of urban rail and road. Specification with pedestrian network shows that pedestrian and rail networks can statistically significantly increase productivity in Hong Kong while roads play a less significant but still meaningful role. Our findings are robust to a variety of sensitivity tests such as using night-time light intensity and residential wage as alternative measures for productivity. The research suggests a key planning policy implication: place-based policies in a dense city require improvement in pedestrian and rail network structure that impacts local and global transport accessibility.

With the deteriorating political situation in Hong Kong in recent years, some measures have been imposed on China by Britain, Australia, Canada, and New Zealand (CANZUK). These have included a joint statement to condemn China and providing a route for Hongkongers to emigrate. This paper takes Hong Kong as an example to explain how Britain can reconnect the Commonwealth by taking a leading role in defending democracy and freedom under the 'post-Brexit Global Britain' banner. This paper argues that CANZUK's actions on Hong Kong can be extended to the Commonwealth, as this is not without precedent. [ABSTRACT FROM AUTHOR]

Minoritised students with dis/abilities in Hong Kong may face aggregated challenges. As a minoritised student with dis/ability or impairment, they may be doubly marginalised or triply marginalised, as in the case of a female or poor minoritised student with dis/ability or impairment. Little is known, however, about these students or about the underpinning philosophies of existing support. Adopting an intersectionality approach and dis/ability critical race theory (DisCrit), this paper explores the educational provision and existing support measures for minoritised students with dis/abilities and the issues and challenges faced by them. It draws on various policy documents from related government departments and others. The paper presents three theoretical arguments: (1) that dis/ability discourse needs to be more inclusive; (2) that the medical model currently provides limited support for minoritised students with dis/abilities in Hong Kong; and (3) that a social model, rather than the current medical model would provide inclusive support.

This paper reports the initial findings of a study about the learning process of 17 pre-service kindergarten teachers in a higher diploma programme at a vocational training institute in Hong Kong. The existing literature regards experiential learning as a reflective process that allows student teachers to make new meaning from learning experiences gained during their training. However, these reflective processes lack commonality, and the findings are rarely situated in the context of vocational education. In this regard, empirical data were gathered as evidence of how student teachers develop their ideas of competence in a vocational training programme based on the perspective of Kolb's experiential learning model. This paper addresses the further implications for programme administrators, institutional fieldwork supervisors and researchers. [ABSTRACT FROM AUTHOR]

This paper takes the development of the British town planning movement as its starting point to explore a series of challenges for the discipline's historiography. The emergence of the professional field involved the circulation of ideas beyond the metropolitan core to colonial territories with spatial interventions that were deemed both physically and morally beneficial. The paper explores the role played by the discipline in developing spatialized forms of ethnic and racial differentiation within colonial territories. I conclude that British planning has largely ignored its own historiography, including the colonial legacy, enabling the discipline to assert its role as a socially progressive profession.

Social inclusion indicators inform policy advocacy and intervention. However, a critical piece of information is often missing: public opinion. Efforts to enhance social inclusion could backfire if they provoke opinion backlash or intergroup hostilities. In this paper, we explain the importance and nuances of inclusive attitudes and develop an easy-to-use survey instrument that tracks public opinion regarding different marginalized groups and support measures systematically. Using evidence from a representative telephone survey in Hong Kong (N = 1010), as well as a parallel online survey (N = 1000), we demonstrate the multidimensional nature of public attitudes toward social inclusion and our instrument's excellent psychometric properties and potential for use in various research settings. Although developed in the context of Hong Kong, the survey items can be decomposed and adapted to suit diverse urban societies. By highlighting the importance and complexity of public opinion, we hope to foster a more participatory approach to promoting social inclusion. [ABSTRACT FROM AUTHOR]

As most other sign languages, Hong Kong Sign Language (HKSL) makes use of verbal classifiers for the purpose of spatial predication. However, a thorough study of the Asian SignBank shows that these same classifier handshapes occur in 76% of all HKSL nouns. In this paper, I argue that these classifier handshapes embedded in nouns are in fact noun classifiers. Under the framework of Distributed Morphology, classifier handshapes are underspecified roots in root compounds which can be assigned the nominal category when merged with a nominal functional head in syntax. The function of these classifiers is to identify, and categorize a discourse referent, and they are full-fledged classifiers according to standards set by the general linguistic literature on classifiers. In addition to verbal and noun classifiers, I also briefly show how HKSL uses mensural numeral classifiers to intervene between mass nouns and numerals within the NP. Taken together, this means that HKSL employs three different types of classifiers: verbal, noun, and numeral classifiers. [ABSTRACT FROM AUTHOR]

Increased glycolysis is a key characteristic of malignant cells that contributes to their high proliferation rates and ability to develop drug resistance. The glycolysis rate-limiting enzyme hexokinase II (HK II) is overexpressed in most tumor cells and significantly affects tumor development. This paper examines the structure of HK II and the specific biological factors that influence its role in tumor development, as well as the potential of HK II inhibitors in antitumor therapy. Furthermore, we identify and discuss the inhibitors of HK II that have been reported in the literature. [ABSTRACT FROM AUTHOR]

Hong Kong was under the direct hit of Severe Typhoon Koinu (2314) on 8 and 9 October 2023, necessitating the issuance of the Increasing Gale or Storm Signal, No. 9. Koinu was a very challenging case for TC forecasting and warning services due to its compact size and erratic movement over the northern part of the South China Sea. This paper reviews the difficulties and challenges of the forecasting aspect of the severe typhoon. The predicted tropical cyclone track and intensity from both conventional models and emerging artificial intelligence models are examined, as well as local wind and rainfall forecast. Experience in this case study showed that while deterministic global models only performed moderately and were not able to adequately support early warning, a regional model and AI models could more effectively support decision making for an operational tropical cyclone warning service.

This paper explores whether the introduction of unconventional monetary policy measures re-shapes the interactions between Hong Kong's housing market and global stock market and economic factors. It is found that, the interactions between Hong Kong's housing prices and global stock markets attenuated during the conventional monetary policy period (CMPP), especially after the Asian Financial Crisis. The level of interactions with global factors reached the lowest during the transitional period between CMPP and the unconventional monetary policy period (UMPP). By contrast, the co-movements with global stock market factors had played a bigger role in explaining Hong Kong's housing price variations during UMPP, especially at the time when the US, UK, EU, and Japan deployed QEs and/or negative interest rate policy. Nevertheless, such high level of integrations did not sustain as QE3 ended in the US. The findings yield important implications in view of recent central bank actions responding to the dim economic prospects due to the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

In this paper, we prove a weak form of the abc$abc$ conjecture generalised to algebraic number fields. Given integers satisfying a+b=c$a+b=c$, Stewart and Yu were able to give an exponential bound in terms of the radical over the integers (Stewart and Yu [Math. Ann. 291 (1991), 225–230], Stewart and Yu [Duke Math. J. 108 (2001), no. 1, 169–181]), whereas Győry was able to give an exponential bound in the algebraic number field case for the projective height HK(a,b,c)$H_{K}(a,\,b,\,c)$ in terms of the radical for algebraic numbers (Győry [Acta Arith. 133 (2008), 281–295]). We generalise Stewart and Yu's method to give an improvement on Győry's bound for algebraic integers over the Hilbert Class Field of the initial number field K. Given algebraic integers a,b,c$a,\,b,\,c$ in a number field K satisfying a+b=c$a+b=c$, we give an upper bound for the logarithm of the projective height HL(a,b,c)$H_{L}(a,\,b,\,c)$ in terms of norms of prime ideals dividing abcOL$abc \mathcal {O}_{L}$, where L is the Hilbert Class Field of K. In many cases, this allows us to give a bound in terms of the modified radical G:=G(a,b,c)$G:=G(a,\,b,\,c)$ as given by Masser (Proc. Amer. Math. Soc. 130 (2002), no. 11, 3141–3150). Furthermore, by employing a recent bound of Győry (Publ. Math. Debrecen 94 (2019), 507–526) on the solutions of S‐unit equations, our estimates imply the upper bound logHLa,b,c

Problem definition: A significant percentage of online consumers place consecutive orders within a short duration. To reduce the total order arrangement cost, an online retailer may consolidate consecutive orders from the same consumer. We investigate how long the retailer should hold the consumer's orders before sending them to a third-party logistics provider (3PL) for processing. In this order-holding problem, we optimize the holding time to balance the total order arrangement cost and the potential delay in delivery. Methodology/results: We model the order-holding problem as a Markov decision process. We show that the optimal order-holding decisions follow a threshold-type policy that is straightforward to implement: Hold any pending orders if the holding time is within a threshold or send them to the 3PL otherwise. Whenever the consumer places a new order, the holding time is reset, and the threshold is updated based on a cumulative set of the past consecutive orders in the consumer's shopping journey. Using a consumer's sequential decision model, we personalize the threshold by finding its closed-form expression in the consumer's order features. We determine the model's coefficients and evaluate the threshold-type policy using the data of the 2020 MSOM Data Driven Research Challenge. Extensive numerical experiments suggest that the personalized threshold-type policy outperforms two commonly used benchmarks by having fewer order arrangements or shorter holding times. Furthermore, personalizing the order-holding decisions is significantly more valuable for "enterprise" customers. Managerial implications: Our research suggests a higher threshold for consumers who are more likely to place consecutive orders within a short duration. The consumers' demographic information has a significant effect on the threshold. Specifically, the threshold is higher for "plus" consumers, female consumers, and consumers in the age group of 16–25 years. The threshold for tier 1 cities is lower than that for tier 2 to tier 4 cities but higher than that for tier 5 cities.

An appropriate urban density is a vital part of a sustainable urban fabric. However, when it comes to measuring the built urban fabric and how people walk through it and use, a difficulty has been observed in defining applicable measurement tools. With the intention of identifying the variables that will allow the best characterization of this fabric and movement, a multi-variable analysis methodology from the field of artificial intelligence (AI) is proposed. The main objective of this paper is to prove the capacity of AI as an evolving research method in urban morphology and specifically to evaluate the capacity of such a methodology to measure the way in which people travel through defined multi-levels of typologies of public urban space. The research uses the case of Hong Kong as a dense city that is three-dimensionally activated in terms of its public realm, not just at street level, but also via below ground subways and upper-level walkways, public and quasipublic spaces. This includes the three-dimensional volumetric assessment of public and quasi-public space typologies within a highly dense city. For the purpose of the study, a characterization and term definition of these spaces has been further developed: "Junctions", "Landmarks", "Intersections", "Districts", "Passages" and "Lobbies" (both outdoor and indoor) based on Lynch's 5 main key elements (District, landmark, path, edges, node). The results obtained using AI prove to be more robust and rational than those based on a more limited range of tools, evidencing that using AI can offer operational opportunities for better understanding of morphological and typological evolution within the vertical and volumetric built urban fabric.

In response to the rapid urban expansion and the burgeoning number of landfill sites, managing water infiltration in these areas has become a critical challenge, especially in cities like Shenzhen, Hong Kong, and Singapore where traditional cover materials such as silt, clayey gravel, and sand are scarce. A three-layer (silt/gravelly sand/clay) capillary barrier cover system has been proposed to address this issue in humid climates. As an alternative to scarce traditional materials, using local soils and construction waste (CW) for this system presents a viable solution. However, the real-world performance of this adapted three-layer system, constructed with local soils and CW under natural rainfall conditions, remains to be fully evaluated. This paper presents a field test evaluating the water infiltration behavior of a three-layer capillary barrier landfill cover system under natural conditions. The tri-layered system is comprised of a 0.6 m loose local unscreened soil layer, covered by a 0.4 m CW layer and topped by a 0.8 m heavily compacted local screened soil layer. Monitoring findings reveal that, during the wet season, infiltration through the top two layers was staved off until the third rainfall, after which these layers retained moisture until 15 September 2016. The fluctuation in pore water pressure in the topmost layers showed each rainfall was contingent not only on the day's precipitation but also the hydraulic state. Beyond the hydraulic state's influence, a deeper tensiometer showed resulted in a diminished correlation between the surge in pore water pressure and daily rainfall. This declining correlation with depth can be attributed to the capillary effect and the reduced permeability of the screened soil layer. Rainfall patterns significantly affect percolation, with the combination of a short-duration, intense rainfall and prolonged weak rainfall resulting in a marked increase in percolation. In the foundational screened soil layer, the pore water pressure remained relatively low, with the cumulative percolation over six months (June to December) registering approximately 10 mm. These findings suggest a promising performance of the three-layer capillary barrier cover system, integrating local soils and CW, in the year of the study conducted in a humid environment.

The Trends in International Mathematics and Science Study 2019 assessment results show a drop in mathematics achievement among Hong Kongese students. While several predictors associated with Hong Kongese students' declining mathematics outcomes in recent years have been explored, only a few of them have interrogated the relationship of teacher-background factors on students' mathematics scores. This paper analyzed the association between teacher characteristics and eighth-grade Hong Kongese students' mathematics scores using the ordinary least squares regression. Findings revealed a statistically significant association between predictors and the dependent variable. Findings suggest that school administrators, educators, policymakers, and researchers attend to teacher-background variables as critical indicators associated with students' mathematics performance among eighth-grade Hong Kongese students and students in similar other country contexts and/or education systems.

The use of infrared thermography (IRT) technique combining other remoting sensing techniques such as photogrammetry and unmanned aerial vehicle (UAV) platforms to perform geotechnical studies has been attempted by several previous researchers and encouraging results were obtained. However, studies using time-lapse IRT survey via a UAV equipped with a thermal camera are limited. Given the unique setting of Hong Kong, which has a high population living in largely hilly terrain with little natural flat land, steep man-made slopes and natural hillsides have caused significant geotechnical problems which pose hazards to life and facilities. This paper presents the adoption of a time-lapse IRT survey using a UAV in such challenging geotechnical conditions. Snapshot and time-lapse IRT studies of a selected site in Hong Kong, where landslides had occurred were carried out, and visual inspection, photogrammetry, and IRT techniques were also conducted. 3D terrain models of the selected sites were created by using data collected from the photogrammetry and single (snapshot) and continuous monitoring (time-lapse) infrared imaging methods applied in this study. The results have successfully identified various thermal infrared signatures attributed to the existence of moisture patches, seepage, cracks/discontinuities, vegetation, and man-made structures. Open cracks/discontinuities, moisture, vegetation, and rock surfaces with staining can be identified in snapshot thermal image, while the gradient of temperature decay plotted in ln(T) vs. ln(t) enables quantifiable identifications of the above materials via time-lapse thermography and analysis.

Aims: Limited research has explored the stressors experienced by veterinarians in East Asia. Metropolitan cities like Hong Kong may have overlooked factors that significantly contribute to veterinarians' stress. This paper examines how clientrelated stressors and contextual factors contribute to the stress levels of Hong Kong-based veterinarians. Methods: Veterinarians from small domestic animal practices in Hong Kong were recruited using purposive and targeted snowball samplings until thematic saturation was achieved. Semi-structured in-depth interviews were conducted, audio-recorded, transcribed, coded, and analysed using reflexive thematic analysis with an interpretivist paradigm based on Heidegger's phenomenological approach. Results: A total of 18 participating veterinarians described the expectations of and communication with the animal-health enthusiast (AHE) community, including clients, pet owners, and animal lovers, as their primary source of stress. Discrepant expectations and miscommunication between the AHE and veterinary communities, along with contextual factors, such as convenience in clinic switching, negative online reviews, and the relatively short history of the veterinary profession in the multilingual city, were identified as contributing factors to their stress. Recent socio-political events and the pandemic further intensified societal emotions, leading some clients to project frustrations onto perceived authority figures, including health professionals. Conclusion: The study highlights that client-related stress extends beyond the health of animal patients, encompassing the expectations of the AHE community, which requires professional-level communication skills to build a mutually respectful three-party relationship. Besides, Hong Kong's unique contextual and historical factors subtly but chronically impact veterinary practices, which can be easily overlooked. Recognising these influences and how they interact is crucial for collaboration, within and beyond the profession, at the policy level to improve veterinary training and practices. Implications: Our findings highlight the importance of expectation management and improving communication quality to foster healthy relationships among animals, the AHE community, and veterinary professionals. These efforts are believed to alleviate veterinarians' stress and enhance the well-being of all parties involved. We recommend incorporating effective communication and self-care discussions into the veterinary curriculum and advocating ongoing training for practising veterinarians. At the community level, encouraging open dialogues between animal caregivers and veterinary professionals can help address expectation discrepancies. [ABSTRACT FROM AUTHOR]

Accurate positioning in urban canyons remains a challenging problem. To facilitate the research and development of reliable and precise positioning methods using multiple sensors in urban canyons, we built a multisensory dataset, UrbanNav, collected in diverse, challenging urban scenarios in Hong Kong. The dataset provides multi-sensor data, including data from multi-frequency global navigation satellite system (GNSS) receivers, an inertial measurement unit (IMU), multiple light detection and ranging (lidar) units, and cameras. Meanwhile, the ground truth of the positioning (with centimeter-level accuracy) is postprocessed by commercial software from NovAtel using an integrated GNSS real-time kinematic and fiber optics gyroscope inertial system. In this paper, the sensor systems, spatial and temporal calibration, data formats, and scenario descriptions are presented in detail. Meanwhile, the benchmark performance of several existing positioning methods is provided as a baseline. Based on the evaluations, we conclude that GNSS can provide satisfactory results in a middle-class urban canyon if an appropriate receiver and algorithms are applied. Both visual and lidar odometry are satisfactory in deep urban canyons, whereas tunnels are still a major challenge. Multisensory integration with the aid of an IMU is a promising solution for achieving seamless positioning in cities. The dataset in its entirety can be found on GitHub at https://github.com/ IPNL-POLYU/UrbanNavDataset. [ABSTRACT FROM AUTHOR]

Background: Since the outbreak of COVID‐19, universities in Hong Kong have implemented online and hybrid teaching modes, making computer‐assisted language learning (CALL) a primary way for English learning. Research on English learning motivation and self‐regulation has seldom considered learners' emotions (satisfaction and preparedness) and the synchronic online courses in a CALL context. Objectives: This study analyses the relationship between Hong Kong university students' motivation and self‐regulation by considering their emotions in computer‐assisted synchronic online English courses. Methods: 311 Hong Kong university students were invited to complete two questionnaires that investigated students' motivation and self‐regulation in computer‐assisted online English courses. SPSS 26 was employed for exploratory factor analysis (EFA) to extract factors and exclude unsuitable items, and confirmatory factor analysis (CFA) was performed to verify the results of EFA. One‐way ANOVA was conducted to detect the impact of personal emotion on motivation and self‐regulation. AMOS 26 was adopted to construct a structural equation model (SEM) to explore the relationship between motivation and self‐regulation in the CALL context. Results and Conclusions: The results show that satisfaction and preparedness positively correlate with online English learning motivation and self‐regulation. Instrumentality‐attitude significantly predicts all factors of self‐regulation via SEM and goal setting significantly predicts all factors of motivation. With feasible English learning goals, Hong Kong university students are more proactive in learning English online where they actively interact with teachers and peers. Implications: Based on the L2 self‐system (Dörnyei, The psychology of the language learner: Individual differences in second language acquisition, 2005) and self‐determination theory (Barnard et al., Internet and Higher Education, 2009, 12, 1–6), this study clarifies the relationship between motivation and self‐regulation in the CALL context, expanding the application scope of the two theories. COVID‐19 has changed the teaching mode greatly, calling for a revolution in language education and learning. This study provides significant pedagogical implications that benefit both learners and teachers in CALL post‐COVID‐19. Lay Description: What is currently known about this topic: Motivation and self‐regulation greatly affect learners' performance in online English learning.There is a correlation between L2 learners' motivation and self‐regulation.Preparedness and satisfaction are related to learners' learning anxiety and motivation and directly affect learners' online learning achievement. What this paper adds: Satisfaction and preparedness positively correlate with online English learning motivation and self‐regulation.Instrumentality‐attitude significantly predicts all factors of self‐regulation via SEM and goal setting significantly predicts all factors of motivation.With feasible English learning goals, Hong Kong university students are more proactive in learning English online where they actively interact with teachers and peers. What are the implications of our topic for practitioners?: Learners and teachers must highlight the importance of satisfaction and preparedness in online English courses.Learners and teachers should attach great importance to the instrumentality‐attitude in the CALL context, and teachers can appropriately reduce the difficulty of English learning and design study content according to the needs of different students.Teachers should assist Hong Kong university students in formulating reasonable and feasible short‐term and long‐term learning goals at the beginning of online English courses.

The consolidation of Hong Kong marine deposits (HKMDs), a typical soft clayey soil in Hong Kong, is a serious concern in engineering practices, such as coastal embankment construction and marine reclamations. Previous research works illustrate that high temperatures could accelerate the rate of consolidation of soft clayey soils, which has a great potential in future applications. Therefore, studies on the consolidation and stress–strain behaviors of clayey soils under various thermal conditions are necessary. In this paper, a modified temperature-controlled oedometer has been developed and employed to investigate the effects of vertical stress and temperature on the consolidation and creep behavior of remolded HKMD with a temperature range of 20°C–60°C. Scanning electrical microscope (SEM) tests were performed to observe the microstructure of HKMD specimens after oedometer tests under different temperatures. The results show that compression index Cc is nearly independent of temperature, while swelling index Cs is slightly affected by the thermal and stress paths. As temperature increases, both permeability and coefficient of consolidation increase, and the duration to the end of primary consolidation is shortened. It has also been found that with an increase of temperature, the preconsolidation pressure decreases, and there is a reduction in linear creep rate and creep strain limit. Both linear and nonlinear creep functions are adopted to analyze the creep behavior. [ABSTRACT FROM AUTHOR]

As social media becomes a major channel of news access, emotions have emerged as a significant factor of news distribution. However, the influence of cultural differences on the relationship between emotions and news sharing remains understudied. This paper investigates the impact of cultural disparities on emotional responses to political news in Hong Kong. We introduce the notion of "emotional profile" to capture cultural differences in the level and structure of audiences' emotional responses to political topics on Facebook news pages. The study was conducted at a highly significant political moment in the former British colony when the National Security Law (NSL) was passed. The study found that readers of China-critical news pages on Facebook express the highest emotional intensity while readers of China's media in Hong Kong express the lowest emotional intensity, and readers of China-supporting media fall in between. Readers of China-critical Facebook news pages express the most anger, but their political news sharing is correlated the most with "wow" and "sad" reactions. In contrast, readers of Facebook pages of China's media in Hong Kong are more likely to react with "love", which is also the emotion most associated with their political news sharing. The notion of "emotional profile" helps discover similarities within and differences across political boundaries of the news ecosystem. We interpret the results with the help of recent scholarly understanding of emotional expression on social media within Hong Kong's political context. [ABSTRACT FROM AUTHOR]

Soil is commonly collected from an outdoor crime scene, and thus it is helpful in linking a suspect and a victim to a crime scene. The chemical profiles of soils can be acquired via chemical instruments such as Ultra-Performance Liquid Chromatography (UPLC). However, the UPLC chromatogram often interferes with an unstable baseline. In this paper, we compared the performance of five baseline correction (BC) algorithms, i.e. asymmetric least squares (AsLS), fill peak, iterative restricted least squares, median window (MW), and modified polynomial fitting, in discriminating 30 chromatograms of brownish soils by five locations of origin, i.e. PP, HK, KU, BL, and KB. The performances of the preprocessed sub-datasets were first visually inspected through the mean chromatograms and then further explored via scores plots of principal component analysis (PCA). Eventually, the predictive performances of the partial least squares-discriminant analysis (PLS-DA) models estimated from 1 000 pairs of training and testing samples (i.e. prepared via iterative random resampling split at 75:25) were studied to identify the best BC method. Mean raw chromatograms of the 10 soil samples were different from each other, with evident fluctuated baselines. AsLS and MW corrected chromatograms demonstrated the most significant improvement compared with the raw counterpart. Meanwhile, the scores plot of PCA revealed that most of the sub-datasets produced three separate clusters. Then, the sub-datasets were modelled via the PLS-DA technique. MW emerged as the excellent BC method based on the mean prediction accuracy estimated using 1 000 pairs of training and testing samples. In conclusion, MW outperformed the other BC methods in correcting the UPLC data of soil. Key points UPLC data of soil interfere with baseline drifts. BC can improve the quality of the pixel-level UPLC data. MW emerges as the most desired algorithm in improving the quality of UPLC data of soil. [ABSTRACT FROM AUTHOR]

Air pollution is a rising environmental concern that has detrimental effects on human health and the environment. Building environment and urban green space features play a crucial role in the dispersion and accumulation of air pollutants. This study examines the impacts of building environment and urban green space on air pollution levels in the highly urbanized city of Hong Kong, focusing on their interaction effects and potential nonlinearity. For the analysis, this paper investigates how building density, building height, building types, urban green space size, and number of urban green space clusters, as well as their interplays, impact PM2.5 concentrations using high-resolution, satellite-based PM2.5 grids coupled with spatial analysis techniques. The findings reveal that a unit increase in the size of urban green space and the standard deviation of building height contribute to a 0.0004 and a 0.0154 reduction in PM levels, respectively. In contrast, air pollution levels are found to be positively associated with building density (0.1117), scatteredness of urban green space (0.0003), and share of commercial buildings (1.0158). Moreover, it has been found that building height presents a U-shape relationship with PM2.5 concentrations. Finally, the negative association between the size of urban green space and air pollution levels tends to be enlarged in districts with more low-rise buildings. This study conveys important building environment and urban green space planning implications. [ABSTRACT FROM AUTHOR]

We show that managerial learning from stock prices can lead to feedback loop vulnerability: corrective actions based on perceived negative market signals reduce the sensitivity of asset payoffs to stock market information. Less sensitivity discourages liquidity provision and increases the price impact of liquidity shocks. Interestingly, overconfident managers who disregard stock price information may be less vulnerable to the adverse price impact of nonfundamental liquidity shocks. Our empirical evidence strongly supports the model's underlying premises and predictions: First, investment decisions of overconfident CEOs are significantly less responsive to stock price fluctuations. Second, the price impact of liquidity shocks, for example, mutual fund fire sales, is substantially smaller for firms with overconfident CEOs. This paper was accepted by Gustavo Manso, finance.

The ℓ 0 trend filtering ( ℓ 0 -TF) is a new effective tool for nonparametric regression with the power of automatic knot detection in function values or derivatives. It overcomes the drawback of ℓ 1 -TF that is known to have bias issues. To solve the ℓ 0 -TF problem, we propose an alternating minimization induced active set (AMIAS) search method based on the necessary optimality conditions derived from an augmented Lagrangian framework. The proposed method takes full advantage of the primal and dual variables with complementary supports, and decouples the high-dimensional problem into two subsystems on the active and inactive sets, respectively. A sequential AMIAS algorithm with warm start initialization is developed for efficient determination of the cardinality parameter, along with the output of solution paths. Theoretically, the oracle estimator of ℓ 0 -TF is justified to behave like regression splines under the continuous time setting with mild conditions. Our numerical experiments include simulation studies for comparing ℓ 0 -TF to ℓ 1 -TF and free-knot splines on several synthetic examples, and a real data application of time series segmentation on Hong Kong PM2.5 indexes.

Train distance estimation in a turnout area is an important task for the autonomous driving of urban railway transit, since this function can assist trains in sensing the positions of other trains within the turnout area and prevent potential collision accidents. However, because of large incident angles on object surfaces and far distances, Lidar or stereo vision cannot provide satisfactory precision for such scenarios. In this paper, we propose a method for train distance estimation in a turnout area based on monocular vision: firstly, the side windows of trains in turnout areas are detected by instance segmentation based on YOLOv8; secondly, the vertical directions, the upper edges and lower edges of side windows of the train are extracted by feature extraction; finally, the distance to the target train is calculated with an appropriated pinhole camera model. The proposed method is validated by practical data captured from Hong Kong Metro Tsuen Wan Line. A dataset of 2477 images is built to train the instance segmentation neural network, and the network is able to attain an MIoU of 92.43% and a MPA of 97.47% for segmentation. The accuracy of train distance estimation is then evaluated in four typical turnout area scenarios with ground truth data from on-board Lidar. The experiment results indicate that the proposed method achieves a mean RMSE of 0.9523 m for train distance estimation in four typical turnout area scenarios, which is sufficient for determining the occupancy of crossover in turnout areas.

Many warehouses involved in e-commerce order fulfillment use robotic mobile fulfillment systems. Because demand and variability can be high, scheduling orders, robots, and storage pods in interaction with manual workstations are critical to obtaining high performance. Simultaneously, the scheduling problem is extremely complicated because of interactions between decisions, many of which must be taken timely because of short planning horizons and a constantly changing environment. This paper models all such scheduling decisions in combination to minimize order fulfillment time. We propose two decision methods for the above scheduling problem. The models batch the orders using different batching methods and assign orders and batches to pods and workstations in sequence and robots to jobs. Order picking and stock replenishment operations are included in the models. We conduct numerical experiments based on a real-world case to validate the efficacy and efficiency of the model and algorithm. Instances with 14 workstations, 400 orders, 300 stock-keeping units (SKUs), 160 pods, and 160 robots can be solved to near optimality within four minutes. Our methods can be applied to large instances, for example, using a rolling horizon. Because our model can be solved relatively fast, it can be used to take managerial decisions and obtain executive insights. Our results show that making integrated decisions, even when done heuristically, is more beneficial than sequential, isolated optimization. We also find that positioning pick stations close together along one of the system's long sides is efficient. The replenishment stations can be grouped along another side. Another finding is that SKU diversity per pod and SKU dispersion over pods have strong and positive impacts on the total completion time of handling order batches.

This paper explores how parents in Hong Kong perceive the impact of the COVID-19 pandemic on the use of academic and non-academic private tutoring (PT) for their children, using a thematic analysis of interviews with 80 parents from diverse ethnic and socioeconomic backgrounds. We seek to understand the role of PT in parents' thinking about their children's learning and developmental needs in uncertain times, which foregrounds parents' temporalities in the face of disruption. We find that maintaining pre-pandemic PT levels was the most common attitude for almost half of the sample, followed by roughly similar groups of parents who increased or decreased their use of PT. Parental perceptions of the functions of PT converged on three main uses: mitigating the effects of schooling disruptions, making productive use of newfound free time and providing a sense of normality. Using a timescapes lens, we identify temporal elements in how PT factored into parents' experiences and perceptions of managing 'gained' and 'lost' time, adapting to remote learning, avoiding health risks and reflecting on inequalities during the COVID-19 pandemic.

On 4 May 2023, the Hong Kong Court of Final Appeal (CFA) delivered a groundbreaking judgment in Re Guy Kwok-Hung Lam [2023] HKCFA 9, in relation to whether a foreign exclusive jurisdiction clause (EJC) should be upheld in insolvency cases.The CFA decided that in an ordinary case where there is an EJC, absent any countervailing factors such as the risk of insolvency affecting third parties and a dispute that borders on the frivolous or abuse of process, the petitioner and debtor out to be held to their contract (‘the Guy Lam Principle’). Following the judgment, two cases have appeared before the Hong Kong Court of First Instance where the court has been asked to consider whether the Guy Lam Principle also applies to arbitration clauses.The Honourable Madam Justice Linda Chan and the Honourable Mr Justice Jonathan Harris have handed down what appear to be diverging judgments on this issue in Re Simplicity &Vogue Retailing (HK) Co Ltd [2023] HKCFI 1443 and Re Shandong Chenming Paper Holdings Ltd [2023] HKCFI 2065, respectively.

Problem description: In many markets with demand uncertainties, competing retailers may share inventories for common products that they offer consumers. This paper examines how competitors' product sharing affects their inventory and service-quality decisions. The existing literature has mainly focused on inventory sharing among independent retailers who do not compete with each other. Our research aims to fill the gap in this literature by investigating the tradeoffs of inventory sharing between retailers who directly compete for customers based on service quality. Methodology/results: We develop a game-theoretical model in which two retailers selling a common product from the same manufacturer compete for customers by offering differentiated services together with the product. Each retailer faces stochastic demand that increases in its service quality and decreases in the competitor's service quality. When a retailer runs out of stock of the product, it may replenish its inventory directly from the manufacturer and/or request the competitor's excess inventory if they have an inventory-sharing agreement. We find that inventory sharing may soften or intensify service competition, depending on the transfer price for the shared inventory. Specifically, when retailers agree to share inventory, their service levels decrease in the transfer price if their preseason inventory levels are exogenous, but are nonmonotone in the transfer price if the retailers endogenously choose inventory levels. Moreover, our analysis reveals that the retailers' equilibrium inventory levels will increase in the transfer price and can be higher or lower than their levels in the case without inventory sharing. We also find that with exogenous inventory, the retailers prefer to share inventory at the highest nonmoot transfer price, whereas with endogenous inventory, the retailers may prefer not to share inventory, even at the optimal transfer price, when the level of competition and the preorder cost are high. Finally, we show that with service competition, inventory sharing cannot achieve full coordination under any transfer price. Managerial implications: When deciding whether to share inventory with competitors, managers should consider not only the benefits of inventory pooling, but also the strategic effect of sharing on the firms' inventory choices and service levels.

While many countries now prioritise accepting skilled migrants to meet labour demand in a globalised economy, retaining them has been a challenge. Low retention is often attributed to immigration policy failures and/or skill mismatches in the labour market. This paper argues that besides career issues, skilled migrants' cultural aspirations and their sense of 'civic belonging' are significant factors when evaluating migration outcomes and the prospect of staying. This paper is based on 44 in-depth interviews with Taiwanese college-educated migrants working in Hong Kong and Tokyo, two major Asian global cities known for attracting foreign talent. The paper found that ambivalence towards staying prevails, due to unfulfilled aspirations for cosmopolitanism—in the case of Tokyo—and frustrations with a limited 'social contract'—in the case of Hong Kong. The implications of these findings could extend the scope of factors to be considered in investigating what shapes migrants' settlement decisions in demographic research. [ABSTRACT FROM AUTHOR]

A systematic literature review revealed that there are few validated youth prevention and positive youth development programs in different Chinese societies. To promote the holistic development of young people in Hong Kong, we developed, implemented, and evaluated the P.A.T.H.S. Project in Hong Kong. Based on the successful experience of the P.AT.H.S. Project in Hong Kong, Tin Ka Ping Foundation supported the development of Tin Ka Ping P.A.T.H.S. Project in mainland China based on the original P.A.T.H.S. programs. Besides adapting the programs to fit the socio-cultural context of mainland China, we also trained teachers, supported the implementation, and evaluated the developed programs. Besides the junior high school programs, we also voluntarily deployed additional financial and manpower resources to develop senior high school programs. To help colleagues understand the project details, we have documented the project, including curriculum manuals, book chapters, journal articles, and conference papers. In this paper, we present the publications arising from Tin Ka Ping Project in mainland China. [ABSTRACT FROM AUTHOR]

Purpose: Consumer studies drawing on interpretative approaches have tended to rely on sedentary interviews, which the authors argue are ill-equipped to capture the embodied, tacit and pre-reflexive knowledge that conditions routinized practices. This paper aims to provide practical and theoretical framing of the walking-with technique, in particular, with reference to practice theories. Specifically, this paper draws on Bourdieu's concept of the "habitus" to illustrate the "workings" of the habituated body in performing routine consumption. Design/methodology/approach: This paper used the walking-with technique to elicit "mobile stories" with senior executives in Hong Kong. This paper explored how walking to and from work/lunch/dinner can open up culturally and historically embodied narratives that reflect evolving consumption practices throughout participants' professional trajectories. Findings: This paper demonstrates the uses of the walking-with technique by illustrating how embodied narratives foreground the pre-reflexive practices of mundane consumption. This paper illustrates how walking as a "mobile mundane practice" can expand a researcher's horizon of understanding, enabling them to "fall into the routines of participants' life", "get into grips with participant's temporal (time travel portal) and cultural conditioning" and "co-experience and empathise with participants through bodily knowing". The authors argue that walking-with necessarily implies an inter-subjective sharing of intermundane space between the researchers and the participants. Such a method is therefore conducive to engendering co-created embodied understanding-in-practice, which the authors argue is accomplished when there is a fusion-of-habituses. Future applications in other consumer contexts are also discussed. Practical implications: The walking-with technique embeds data collection in the day-to-day routes taken by participants. This does not only ease the accessibility issue but also render real-life settings relevant to participants' daily life. Originality/value: Despite receiving growing attention in social science studies, the walking-with technique is under-used in consumer research. This paper calls for the need to mobilise walking-with as a method to uncover practical and theoretical consumer insights in a way that allows for embodied and performative knowledge (know-how) to emerge.

Set against a background of societal pressure and preference for English language education in Hong Kong, this paper explores the policy and practice of English medium instruction (EMI) from the perspective of one group of content subject teachers. Grounded in Bakhtin's dialogism, the paper reports the results of a qualitative study that used in-depth interviews to explore the perspectives and experiences of these teachers as they implement EMI policy in Hong Kong schools. The results reveal the existence of several discourses of EMI in Hong Kong that position the teachers at community, institutional, and professional levels. The results also suggest that the interplay of EMI discourses can offer content subject teachers positions which they regard as undesirable. Suggestions for ensuring that the voices of these teachers are heard within the context of teacher professional development opportunities in EMI settings are considered and implications for future research are discussed.

Bilingual education programmes are characterised by the use of students' second/foreign/additional language (L2) as the medium of instruction for content subjects. In many educational contexts, such programmes are implemented by content subject specialists who have not received sufficient training in helping students master content and L2 simultaneously. Professional development is therefore necessary for this group of teachers. One potential professional development model is promoting collaboration between content and L2 teachers in the same school. Previous studies have explored different forms of cross-curricular collaboration, teachers' attitudes and factors affecting its effectiveness. This paper seeks to extend the current discussion by investigating different models of teacher collaboration, based on a multi-case study of secondary schools adopting English (L2) as the medium of instruction for some or all subjects in Hong Kong. With various sources of data and cross-case comparison, this paper conceptualises a continuum of teacher collaboration in bilingual education programmes. [ABSTRACT FROM AUTHOR]

The emergence of "translanguaging" as a concept referring to bilingual practices has challenged the appropriateness of "code-switching" – the term that has been most influential in studies of bilingualism and language mixing. Reassessing the literature on Cantonese-English mixing in Hong Kong, this paper suggests that the kind of spontaneous code-switching in peer talk, largely intra-sentential (or intra-clausal) and intra-turn, can indeed be recast as translanguaging, where speakers transcend language boundaries between Cantonese and English for the purpose of meaning-making. Nevertheless, Hong Kong speakers do constantly draw language boundaries by marking words as English or Cantonese, both in metalinguistic judgment and in real-time language production. Revisiting an unpublished dataset of radio talk, this paper further illustrates a number of sequences in which Cantonese speakers may "languagise" the code-switched words or expressions as "English". It is concluded that, in a Conversation-Analytic understanding, the difference between "translanguaging" and "code-switching" boils down to "languagising", and the contrast between the two notions may have been overstated.
