Abstract
Purpose
Effective BIM application hinges on the development of appropriate strategies for its implementation. Though some strategies have been deployed to facilitate BIM implementation in China, their outcomes are not clear. The purpose of this paper is to provide recommendations regarding appropriate strategies for promoting the development and implementation of BIM in China based on lessons learned from advanced implementation experiences in other countries.
Design/methodology/approach
First, existing strategies are investigated and barriers to BIM implementation mentioned in previous studies are summarized. Then, the identified barriers are mapped to the strategy contents. Finally, a comparative analysis on different areas is conducted to propose suggestions for identified items of BIM implementation strategies that need to be improved.
Findings
Six unaddressed barriers to BIM implementation strategies in China were identified from the mapping results: insufficient government lead/direction, organizational issues, legal issues, high cost of application, resistance to change of thinking mode and insufficient external motivation.
Originality/value
The findings of this study can be used to facilitate the development of appropriate strategies within the public and private sectors for promoting BIM implementation in China and elsewhere.

Abstract
Purpose
This study aims to investigate the relationship between employee polychronicity and employee creativity. This study also explores the mediating role of employee resilience in the relationship between employee polychronicity and employee creativity.
Design/methodology/approach
This study was based on a quantitative research design, and a survey instrument was used to collect data from doctors and nurses. Ordinary least squares (OLS) regression and four-step Baron and Kenney (1986) approaches were used to check the impact of nurses’ polychronicity on creativity through resilience.
Findings
Results proved that employee polychronicity positively influences employee creativity. The finding indicates that employee resilience acts as a mediator in the relationship between employee polychronicity and employee creativity.
Originality/value
The worth of this study rests on the deeper understanding of the employee polychronicity–employee creativity link in the health-care sector. Moreover, by bringing to the fore employee resilience as a mediator of the polychronicity–creativity relationship, this study provided a new vantage point to explore the intricacies concerned with the relationships between polychronicity, resilience and creativity.

Abstract
Purpose
Recent research has recognised the importance of supply chains and ecosystems as key drivers of successful servitization strategies, especially in the context of inter-organisational relations (IOR). The body of knowledge has, however, become increasingly fragmented and diverse due to different disciplinary roots of both servitization and IOR research. The purpose of this paper is to take stock of current knowledge and to generate a set of future research directions for servitization-related supply chain and ecosystem research.
Design/methodology/approach
A systematic review methodology was applied. A thematic analysis was conducted on a sample of 34 papers in the period 2010–2021 to identify the key themes within the servitization-related supply chain and ecosystem literature.
Findings
The review revealed a limited, but expanding, knowledge base for servitization-related supply chain and ecosystem research. The findings provide insight into current trends across four thematic areas: theoretical orientation, methodological approaches, research context and research content. Within these themes, it was found that four main areas of research content have been studied (supplier relationships, risk perception and uncertainty, capability development and resource integration), with most research adopting case-based methodologies within three main industrial contexts: manufacturing, industrial and software. Finally, a broad range of theoretical orientations have led to an increasingly fragmented and diverse literature base.
Originality/value
This study is the first to review servitization-related supply chains and ecosystems. It contributes insights through an IOR lens to categorise and organise a core set of themes and concepts for servitization-related supply chain and ecosystems research. It identifies research gaps within the extant literature and presents a set of future research directions.

Abstract
Purpose
The purpose of this paper is to propose a control approach for small unmanned helicopters, and a novel swarm intelligence algorithm is used to optimize the parameters of the proposed controller.
Design/methodology/approach
Small unmanned helicopters have many advantages over other unmanned aerial vehicles. However, the manual operation process is difficult because the model is always instable and coupling. In this paper, a novel optimized active disturbance rejection control (ADRC) approach is presented for small unmanned helicopters. First, a linear attitude model is built in hovering condition according to small perturbation linearization. To realize decoupling, this model is divided into two parts, and each part is equipped with an ADRC controller. Finally, a novel Levy flight-based pigeon-inspired optimization (LFPIO) algorithm is developed to find the optimal ADRC parameters and enhance the performance of controller.
Findings
This paper applies ADRC method to the attitude control of small unmanned helicopters so that it can be implemented in practical flight under complex environments. Besides, a novel LFPIO algorithm is proposed to optimize the parameters of ADRC and is proved to be more efficient than other homogenous methods.
Research limitations/implications
The model of proposed controller is built in the hovering action, whereas it cannot be used in other flight modes.
Practical implications
The optimized ADRC method can be implemented in actual flight, and the proposed LFPIO algorithm can be developed in other practical optimization problems.
Originality/value
ADRC method can enhance the response and robustness of unmanned helicopters which make it valuable in actual environments. The proposed LFPIO algorithm is proved to be an effective swarm intelligence optimizer, and it is convenient and valuable to apply it in other optimized systems.

Abstract
Purpose
Microblogs are communication platforms for companies and consumers that challenge companies' brand marketing strategies. This paper provides a theoretical basis for expanding microblog applications and a practical basis for improving the effectiveness of brand marketing.
Design/methodology/approach
The authors use factor analysis to extract the factors of microblog user influence and construct a structural equation model to reveal the interaction mechanism of the influencing factors. Additionally, the authors clarify the promotion and enhancement effects of these factors.
Findings
Microblog user influence can be converted into richness, interaction and value factors. The richness factor significantly affects the latter two, whereas the interaction factor does not affect the value factor.
Research limitations/implications
First, the sample used is limited to media industry practitioners. To increase generalizability, diverse groups should be included in future studies. Second, this model's theoretical explanatory ability can be further developed by adding other meaningful factors beyond the existing ones.
Originality/value
This study analyzes the factors of microblog user influence in China and validates the relevant elements. As a result, it improves the influence research on social media users and benefits the practice of information recommendation and microblog marketing.

Abstract
Purpose
This research aims to examine the impact of friction stir processing (FSP) treatment on an aluminum alloy, especially the AD31T alloy derived from the Al-Fe-Mg-Si system. The aim is to assess the influence of different processing techniques on the microstructure and physical and mechanical characteristics of the material, with a specific focus on structural and bulk imperfections inside the stir zone (SZ).
Design/methodology/approach
The study demonstrates that augmenting the linear velocity of the tool within the 25–100 mm/min range results in significant enhancements. The enhancements include a decrease in the heat-affected zone (HAZ), a reduction in the extent of volume defects inside the SZ and a more uniform deformation. The microstructural analysis results are corroborated by data acquired from microhardness and electrical conductivity studies, confirming the beneficial influence of modifying the tool’s linear velocity on the material parameters.
Findings
This study provides significant observations on the changes in microstructure and the generation of flaws throughout the process of FSP of AD31T alloy. These results have practical implications for improving the characteristics of the alloy and optimizing the production conditions.
Originality/value
All samples exhibit a distinct reduction in electrical conductivity within the initial third of the sample, aligning with the transitional region between the base metal (BM) and the HAZ. This underscores the importance of understanding the transitional zones during FSP.

Abstract
Purpose
Despite the construction industry's significant impact on high energy use and a growing carbon footprint, technologies like Green BIM help to optimize natural resources, reduce pollution, use sustainable space and work on human comfort and health. But the trend in a holistic approach is minimal. Thus, the paper aimed to systematically investigate Green BIM research and implementation trends using a mixed-method and also show the prospects of holistic Green BIM implementation.
Design/methodology/approach
First, we conducted a Scientometrics analysis on the topic using the Scopus database for the time interval of (2013–present). Secondly, the Qualitative Content Review method asserted the Scientometrics analysis result. Lastly, exploratory research was done on secondary data to compare the AEC industry trend for a comprehensive view.
Findings
The merged findings confirmed the partial implementation of Green BIM and of which 43% of research focused only on energy analysis. Despite the potential of BIM and the interrelationship among green building parameters, the result showed other aspects of green building and sustainable design parameters as green material selection, sustainable site, waste management and water-use efficiency not comprised.
Originality/value
The authors propose a new conceptual framework for integrating green building parameters, BIM tools and green building assessment tools in a life cycle of a project that adds into the sustainability of the Architectural, Engineering and Construction sector. The study would help to provoke researchers, software developers and practitioners for further innovative effort in holistic Green BIM implementation.
