Abstract
Purpose
This paper critically analysed 195 articles with the objectives of providing a clear understanding of the current City Information Modelling (CIM) implementations, identifying the main challenges hampering the uptake of CIM and providing recommendations for the future development of CIM.
Design/methodology/approach
This paper adopts the PRISMA method in order to perform the systematic literature review.
Findings
The results identified nine domains of CIM implementation including (1) natural disaster management, (2) urban building energy modelling, (3) urban facility management, (4) urban infrastructure management, (5) land administration systems, (6) improvement of urban microclimates, (7) development of digital twin and smart cities, (8) improvement of social engagement and (9) urban landscaping design. Further, eight challenges were identified that hinder the widespread employment of CIM including (1) reluctance towards CIM application, (2) data quality, (3) computing resources and storage inefficiency, (4) data integration between BIM and GIS and interoperability, (5) establishing a standardised workflow for CIM implementation, (6) synergy between all parties involved, (7) cybersecurity and intellectual property and (8) data management.
Originality/value
This is the first paper of its kind that provides a holistic understanding of the current implementation of CIM. The outcomes will benefit multiple target groups. First, urban planners and designers will be supplied with a status-quo understanding of CIM implementations. Second, this research introduces possibilities of CIM deployment for the governance of cities; hence the outcomes can be useful for policymakers. Lastly, the scientific community can use the findings of this study as a reference point to gain a comprehensive understanding of the field and contribute to the future development of CIM.

Abstract
Purpose
Gifting is a typical monetization strategy for live streaming platforms to motivate providers’ live content contribution. However, research regarding the factors that affect individuals’ gifting intention is still at an infant stage. Therefore, this study aims to investigate the factors that affect individuals’ gifting intention during live streaming.
Design/methodology/approach
The authors build a model to uncover the factors that affect individuals’ gifting intention from a streamer–content perspective, and the hypotheses are largely validated by online survey data through structural equation model analysis.
Findings
Individuals’ perceived attractiveness of the streamers is significantly and positively associated with gifting intention for leisure-related live streaming, whereas individuals’ perceived similarity with the streamers is significantly and positively associated with gifting intention for leisure-related and non-leisure-related live streaming. For live content-related factors, the individuals’ perceived utilitarian value of content is significantly and positively associated with gifting intention for non-leisure-related live streaming, whereas the individuals’ perceived hedonic value is significantly positively associated with gifting intention for leisure-related live streaming. Perceived symbolic value is insignificantly associated with gifting intention for neither type of live streaming.
Originality/value
The research is an original work and significantly contributes to live streaming and PWYW literature, and the findings derived from this study can guide live streaming platforms to regulate individuals’ gifting intentions/behaviors better.

Abstract
Purpose
The present study focused on examining the effect of treated wastewater (TWW) on soil chemical properties. Also, efforts were made to compare the soil chemical properties under TWW irrigation with that under groundwater (GW).
Design/methodology/approach
During the years 2021 and 2022, surface and subsurface soil samples were randomly collected in triplicate by using an auger fortnightly at two depths (20 and 40 cm) from the selected spot areas to represent the different types of irrigation water sources: TWW and GW. Samples of the GW and the TWW were collected for analysis.
Findings
This study examines the impact of TWW on soil characteristics and the surrounding environment. TWW use enhances soil organic matter, nutrient availability and salt redistribution, while reducing calcium carbonate accumulation in the topsoil. However, it negatively affects soil pH, electrical conductivity and sodium adsorption ratio, although remaining within acceptable limits. Generally, irrigating with TWW improves most soil chemical properties compared to GW.
Originality/value
In general, almost all of the soil’s chemical properties were improved by irrigating with TWW rather than GW. Following that, wastewater is used to irrigate the soil. Additionally, the application of gypsum to control the K/Na and Ca/Na ratios should be considered under long-term TWW and GW usage in this study area in order to control the salt accumulation as well as prevent soil conversion to saline-sodic soil in the future. However, more research is needed to thoroughly investigate the long-term effects of using TWW on soil properties as well as heavy metal accumulation in soil.

Abstract
Purpose
This study is dedicated to investigate why Mainland Chinese students pursuing higher education in Hong Kong are more likely to return to first-tier cities in Mainland China rather than stay in Hong Kong after graduation, despite Hong Kong’s increasing efforts to retain them as talent. By identifying the rationale that leads them to make such a choice, a critical gap in talent retention strategies for emerging education hubs can thus be addressed.
Design/methodology/approach
Through semi-structured interviews among 20 Mainland Chinese students have recently graduated from Hong Kong institutions, this study analyzes the two-way push and pull factors between Hong Kong and first-tier cities in China, elucidating how international students are influenced by various factors and make the common decisions to go to first-tier cities rather than Hong Kong after graduation.
Findings
The study reveals that while Hong Kong’s favorable visa policies and sector-specific employment opportunities serve as significant pull factors, they are outweighed by the comparative advantages of first-tier cities in mainland China. The comparative advantages of first-tier cities in China, including stronger economic incentives, better social integration prospects and more attractive talent recruitment policies, ultimately determine students' destination choices.
Research limitations/implications
One major limitation lies in the relatively small and specific sample size, which may not fully capture the diversity of experiences among the targeted population. Moreover, the potential destinations of graduates are not limited to Hong Kong or the first-tier cities in China.
Originality/value
This research extends the traditional two-way push-pull theory by integrating comparative advantage analysis, offering a nuanced framework to evaluate international student mobility and talent retention dynamics. The research simultaneously provide insights for policymakers and higher education institutions to refine talent retention strategies, enhance the appeal of emerging education hubs and better align policies with global student mobility trends.

Abstract
Purpose
The purpose of this paper is to review the recent studies on opinion polarization and disagreement.
Design/methodology/approach
In this work, recent advances in opinion polarization and disagreement and pay attention to how they are evaluated and controlled are reviewed.
Findings
In literature, three metrics: polarization, disagreement and polarization-disagreement index are usually adopted and there is a tradeoff between polarization and disagreement. Different strategies have been proposed in literature which can significantly control opinion polarization and disagreement based on these metrics.
Originality/value
This review is of crucial importance to summarize works on opinion polarization and disagreement and to the better understanding and control of them.

This study examines the impact of debt maturity structure on stock price crash risk (SPCR) in Asian economies and the moderating effect of firm age on this relationship.
Abstract
Purpose
This study examines the impact of debt maturity structure on stock price crash risk (SPCR) in Asian economies and the moderating effect of firm age on this relationship.
Design/methodology/approach
The study utilized annual data from 432 nonfinancial firms publicly listed in six Asian countries: China, Hong Kong, Japan, Singapore, Pakistan and India. The observation period covers 14 years, from 2007 to 2020. The sample was categorized into three groups: the entire sample and one group each for developing and developed Asian economies. A generalized least squares panel regression method was employed to test the research hypotheses.
Findings
The results suggest that long-term debt has a significant negative influence on SPCR in Asian economies, indicating that firms with high long-term debt experience lower future SPCR. Moreover, firm age negatively moderates this relationship, implying that older firms may experience a more pronounced reduction in SPCR due to high long-term debt. Finally, firms in developed Asian economies with high long-term debt are more effective in mitigating the risk of a significant drop in their stock prices than firms in developing Asian economies.
Originality/value
This study contributes to the literature in several ways. To the best of the researcher’s knowledge, this is the first of such efforts to investigate the relationship between debt maturity structure and crash risk in Asia. Additionally, it reveals that long-term debt influences SPCR directly and indirectly in Asia through the moderating role of firm age. Lastly, it is likely one of the first studies by a research team in Asia to compare the nonfinancial markets of developed and developing Asian countries.
