Abstract

Purpose

Prefabricated construction (PC) can benefit construction industry due to its high efficiency, energy saving, consumption reduction and safety. However, the high capital cost is a critical challenge hindering its development in China. The collaboration of PC stakeholders is conducive to improving cost management efficiency and optimizing resource allocation which has been ignored in previous studies. Therefore, this study aims to explore the collaboration paths of stakeholders in the process of solving critical cost influencing factors (CIFs) of PC to reduce costs.

Design/methodology/approach

Firstly, 25 CIFs and five main stakeholders that affect PC capital cost were identified through literature research and expert interviews. Then, questionnaires were used to investigate the relationship between stakeholders and CIFs from the perspectives of three stakeholder attributes of proximity, attitude and power, respectively. Finally, based on the survey data, three stakeholder-CIF networks from three attributes perspective and a comprehensive network were constructed and used for subsequent social network analysis.

Findings

(1) Stakeholders mainly show willingness and potential to collaborate on organization and management factors; (2) More stakeholders pay attention to incentive policies and the setting of prefabrication rates and assembly rates, while all stakeholders have the right to facilitate information and resource sharing in the PC supply chain; (3) The comprehensive network shows a core-periphery structure. As core stakeholders, contractor, designer and manufacturer are more likely to actively manage the 14 core CIFs.

Originality/value

This paper innovatively combined stakeholder and cost management in PC, and used two-mode network based on three stakeholder perspectives to reveal the collaboration potential and motivation of stakeholders in PC cost management. The findings not only provide guidance for stakeholders to find potential partners and optimize resource allocation in solving specific cost issues, but also facilitate stakeholders' sustainable collaboration to achieve PC's cost performance.

Abstract

Purpose

Research into older adults' use of social media remains limited. Driven by increasing digitalisation in China, the authors focus on Chinese older adults (aged 60–75)’ use of WeChat.

Design/methodology/approach

This study used a qualitative interpretive approach and interviewed Chinese older adults to uncover their social practices of WeChat use in everyday life.

Findings

By using social practice theory (SPT), the paper unfolds Chinese older adults' social practices of WeChat use in everyday life and reveals how they adopt and resist the drastic changes in Chinese society.

Originality/value

The study contributes to new understandings of SPT from technology use by emphasising the dynamic characteristics of its three elements. The authors synthesise both adoptions and resistance in SPT and highlight the importance of understanding three elements interdependently within specific contexts, which are conditioned by structure and agency.

Abstract

Purpose

As the debate over CEO duality’s impact on firm performance is still ongoing, the purpose of this study is to redefine CEO duality in Thai family firms and examine its impact on the relationship between earnings management and firm performance.

Design/methodology/approach

This study uses a sample of 1,360 firm-year observations from listed firms on the Stock Exchange of Thailand. A fixed effect regression is used to obtain the empirical results. The results of this study are further validated using two-stage least squares estimation, subsample regression and an alternative measure of family firms.

Findings

This study finds that firms with CEO duality are more likely to engage in REM, supporting Agency Theory. However, family-controlled firms with CEO duality engage less in REM in pursuit of firm performance. This study’s findings highlight the potential benefits of CEO duality in family firms as a mechanism to support Socioemotional Wealth of the controlling family. Therefore, the mandatory ban on CEO duality may have unintended consequences for family firms.

Originality/value

This paper provides further evidence on the impact of CEO duality on the relationship between earnings management and firm performance in Thailand’s family-dominated stock market. A new definition of CEO duality is proposed, including firms where the CEO is related to the chair of the board. This boarder definition provides more comprehensive measurement compared to the traditional definition which may fail to capture the full scope of influence exerted by controlling family, as they may obscure CEO duality by appointing individuals with kinship ties to the CEO as the chair of the board.

Abstract

Purpose

In large-scale environments, LIO-SAM (Tightly-coupled Lidar Inertial Odometry via Smoothing and Mapping) exhibits poor robustness due to the accumulation of errors caused by factors such as the prevalence of similar surroundings and the lack of features in certain open areas. Therefore, the purpose of this study is to optimize the loop detection module of LIO-SAM to reduce error accumulation and enhance mapping and localization performance.

Design/methodology/approach

Based on the LIO-SAM framework, the LinK3D (Linear Keypoints Representation for 3D LiDAR Point Cloud) feature extraction algorithm is integrated in the front end, while the BoW3D (Bag of Words for Real-Time Loop Closing in 3D LiDAR SLAM) loop detection algorithm is integrated in the back end. The features extracted by LinK3D serve as the range factors for the LiDAR, the BoW3D generates loop closure factors and these, along with inertial measurement unit (IMU) preintegration factors and global positioning system (GPS) factors, are added to the factor graph of LIO-SAM. This addition of constraints enhances the mapping and localization effects, optimizing the overall mapping and localization performance.

Findings

Based on the electrically controlled car, experiments were conducted in the experimental scenario proposed in this paper. Compared to LIO-SAM, the method presented in this paper significantly reduces cumulative errors. While ensuring real-time performance, it demonstrates superior mapping and localization effects.

Originality/value

This paper proposes and validates a method that integrates LinK3D, BoW3D and LIO-SAM, named LB-LIOSAM, which enhances the accuracy of feature extraction, optimizes the loop detection module of LIO-SAM and improves its mapping and localization performance in specific environmental scenarios.

Abstract

Purpose

Drawing upon strengths-based inclusive work theory, this study explores how strengths-based leadership promotes employee career sustainability, particularly in the absence of protean career orientation (PCO), with career adaptability as a mediator.

Design/methodology/approach

A three-wave survey of 329 Chinese employees tested the moderated mediation model. Hypotheses were assessed using SPSS 26.0 and Mplus 8.3.

Findings

Strengths-based leadership positively influences career adaptability, leading to greater career sustainability. The effect is stronger when PCO is low, highlighting the compensatory role of strengths-based leadership.

Originality/value

The present paper extends the existing literature on strengths-based leadership and unveils that strength-based leadership can compensate for a lack of PCO. Also, it augments strengths-based inclusive work theory and provides meaningful insights to cultivate employee career sustainability.

Research limitations/implications

The cross-sectional design and self-reported data limit causal conclusions. Future research should use longitudinal methods and diverse cultural contexts to improve generalizability.

Abstract

Purpose

The purpose of this study is to evaluate the effect of graphene, basalt flakes and their synergy on the corrosion resistance of zinc-rich coatings. As the important heavy-duty anticorrosion coatings, zinc-rich coatings provided cathodic protection for the substrate. However, to ensure cathodic protection, a large number of zinc powder made the penetration resistance known as the weakness of zinc-rich coatings. Therefore, graphene and basalt flakes were introduced into zinc-rich coatings to coordinate its cathodic protection and shielding performance.

Design/methodology/approach

Three kinds of coatings were prepared; they were graphene modified zinc-rich coatings, basalt flakes modified zinc-rich coatings and graphene-basalt flakes modified zinc-rich coatings. The anticorrosion behavior of painted steel was studied by using the electrochemical impedance spectroscopy (EIS) technique in chloride solutions. The equivalent circuit methods were used for EIS analysis to obtain the electrode process structure of the coated steel system. Simultaneously, the corrosion resistance of the three coatings was evaluated by water resistance test, salt water resistance test and salt spray test.

Findings

The study found that the addition of a small amount of graphene and basalt flakes significantly improved the anticorrosion performance of coatings by enhancing their shielding ability against corrosive media and increasing the resistance of the electrochemical reaction. The modified coatings exhibited higher water resistance, salt water resistance and salt spray resistance. The graphene-basalt flakes modified zinc-rich coatings demonstrated the best anticorrosion effect. The presence of basalt scales and graphene oxide in the coatings significantly reduced the water content and slowed down the water penetration rate in the coatings, thus prolonging the coating life and improving anticorrosion effects. The modification of zinc-rich coatings with graphene and basalt flakes improved the utilization rate of zinc powder and the shielding property of coatings against corrosive media, thus strengthening the protective effect on steel structures and prolonging the service life of anticorrosion coatings.

Originality/value

The significance of developing graphene-basalt flakes modified zinc-rich coatings lies in their potential to offer superior performance in corrosive environments, leading to prolonged service life of metallic structures, reduced maintenance costs and a safer working environment. Furthermore, such coatings can be used in various industrial applications, including bridges, pipelines and offshore structures, among others.

Abstract

Purpose

This study aims to build on social comparison theory to develop a theoretical model of leader–member exchange (LMX) relationship to workplace ostracism through perceived organizational status by coworkers and envy. This study further proposes that warmth and competence may potentially moderate these two indirect effects.

Design/methodology/approach

This study tested the hypotheses in a battery manufacturing company located in South China by a survey of 216 employees organized in 55 work teams, using different sources. Additionally, the authors conduct two online vignette experiments to test this study’s mediation, proving the causality.

Findings

The authors found that high-level LMX leads to both envy and perceived organizational status by coworkers, which results in a mixed blessing on workplace ostracism toward the employee with high-level LMX. The focal employee’s warmth and competence moderate these indirect relationships.

Research limitations/implications

The authors use LMX to explore antecedents of workplace ostracism and explain how and when these focal employees suffer workplace ostracism from their coworkers. The authors extend the research on LMX by examining the interpersonal risk of being a focal employee. The authors discover two critical boundary conditions – warmth and competence.

Practical implications

This study suggests that it is important to balance the level of the differential LMX; appropriately endorsing other members is a good way to avoid eliciting envy and opposition. Meanwhile, person-oriented citizenship behaviors such as demonstrations of concern or help may shortly build up an employee’s warm impression on their coworkers.

Originality/value

By discovering the bright and dark sides of LMX, this paper has the potential to advance theories on LMX and workplace ostracism. Therefore, the authors believe the current research will have an important impact on relevant research in the future.

Abstract

Purpose

Video game streaming (VGS) is emerging as an extremely popular, highly interactive, inordinately subscribed and very dynamic form of digital media. Incorporated environmental elements, gratifications and user pre-existing attitudes in VGS, this paper presents the development of an extended model of uses and gratification theory (EUGT) for predicting users' behavior in novel technological context.

Design/methodology/approach

The proposed model was empirically tested in VGS context due to its popularity, interactivity and relevance. Data collected from 308 VGS users and structural equation modeling (SEM) was employed to assess the hypotheses. Multi-model comparison technique was used to assess the explanatory power of EUGT.

Findings

The findings confirmed three significant types elements in determining VGS viewers' engagement, including gratifications (e.g. involvement), environmental cues (e.g. medium appeal) and user predispositions (e.g. pre-existing attitudes). The results revealed that emerging technologies provide potential opportunities for new motives and gratifications, and highlighted the significant of pre-existing attitudes as a mediator in the gratification-uses link.

Originality/value

This study is one of its kind in tackling the criticism on UGT of considering media users too rational or active. The study achieved this objective by considering environmental impacts on user behavior which is largely ignored in recent UGT studies. Also, by incorporating users pre-existing attitudes into UGT framework, this study conceptualized and empirically verified the higher explanatory power of EUGT through a novel multi-modal approach in VGS. Compared to other rival models, EUGS provides a more robust explanation of users' behavior. The findings contribute to the literature of UGT, VGS and users' engagement.

Abstract

Purpose

This study reviews research applying Space Syntax, in conjunction with other methodologies, to explore walkability and socio-spatial relations in urban environments, with a particular emphasis on moderate- and low-density city centers.

Design/methodology/approach

A systematic literature review was conducted following PRISMA guidelines, reviewing English-language studies published from 2013 to 2023, involving introduction to research context, information sources and search strategy, screening process and application of eligibility and inclusion criteria to ensure a comprehensive evaluation of relevant papers.

Findings

This research highlights that the predominant focus in the literature has been on high-density city centers in existing Space Syntax studies, revealing a significant gap in understanding socio-spatial dynamics, particularly in moderate- and low-density city centers. Furthermore, this research found that technology-based tools were the most frequently used in past studies, with 454 instances, compared to participatory tools (191 instances) and observational tools (57 instances), when using Space Syntax as an integrated approach to explore socio-spatial relations in urban environments. Moreover, emerging technology-based tools remain the least used technological tools in the literature. Combining these approaches represents a recent trend that could offer valuable insights into pedestrian socio-spatial experiences in both broader urban contexts and smaller-scale city centers.

Originality/value

Unlike previous literature reviews on Space Syntax that neglected its use as an integrated approach, this study uniquely explores the correlation between spatial configurations and human experiences through a review of studies that combine space syntax with other methods, including observational, participatory and technology-based tools to pinpoint the gaps. The research recommends further exploration of pedestrians’ socio-spatial needs by integrating Space Syntax with trends and less-explored technology-based tools.

Abstract

The chapter constitutes a conceptual paper aimed at furnishing a roadmap for the implementation of a coopetition strategy within tourism destinations. This endeavour was prompted by numerous inquiries from industry practitioners seeking guidance on integrating coopetition into their operations. The roadmap delineates six sequential steps for establishing a robust coopetition network, complemented by a toolkit designed to oversee the implementation process and its ensuing outcomes. Key components of this toolkit include the Coopetition Value Proposition, Coopetition Players Mapping and the Coopetition Toolbox, each serving as indispensable resources for navigating the intricacies of coopetition strategy in the tourism sector. In amalgamating theoretical insights with practical applications, our approach not only deepens comprehension of coopetition within the context of strategic management but also equips stakeholders with the requisite tools to harness coopetition's potential for generating social, economic and environmental value. Furthermore, our methodology transcends the boundaries of the tourism industry, offering a versatile framework adaptable to diverse sectors. Through this concerted effort, we endeavour to facilitate the transition of tourism destinations towards the coopetitiveness paradigm, wherein collaboration and competition intertwine to propel sustainable growth and innovation. Ultimately, our chapter serves as a guiding beacon for tourism stakeholders, offering a structured pathway towards embracing coopetition as a cornerstone of strategic management, thus fostering prosperity and resilience amidst evolving market dynamics.
