Since the theory of planned behavior (TPB) was proposed by Ajzen in 1985, it has attracted extensive interest and been widely applied worldwide. Although an increasing number of studies have employed the TPB in the domain of environmental science, there have been no attempts to retrospectively analyze existing articles. The current study aimed to holistically understand the application status of the TPB in environmental science from a knowledge domain visualization perspective. A total of 531 journal articles were obtained through the Scopus database to perform a bibliometric analysis and content analysis. The results showed that waste management, green consumption, climate and environment, saving and conservation, and sustainable transportation are the primary research topics; the United States (U.S.), Mainland China, the United Kingdom (UK), and Malaysia are the most productive countries/regions. Moreover, the cross-disciplinary situations, main source journals, and key articles were revealed. Furthermore, the extended factors, integrated theories, major methods, specific groups, and control variables of environmental science research using the TPB were elaborated and integrated into a comprehensive application framework. Constructive criticisms were ultimately discussed. The findings contribute in several ways to help relevant researchers learn about the application of TPB to environmental science and provide new insights and holistic references for further research on environment-related behavior.

In China, dockless bike-sharing programs (DBSPs) play a significant role in promoting the goals of sustainable urban travel and carbon emissions reduction. However, the sustainability of DBSPs is increasingly being challenged as various issues associated with different stakeholders emerge. While numerous studies have focused on the barriers to traditional bike-sharing programs, the sustainability performance of new-generation DBSPs is largely overlooked. It is accordingly imperative to understand the primary challenges that impede the sustainability of DBSPs and to consider what stimulative measures can be taken. In this study, we investigate the factors that are critical to DBSPs' sustainability from a network perspective. Stakeholder-associated factors and their interrelations were identified via literature analysis and interviews, and the social network analysis (SNA) method was employed to recognize the critical factors and links in DBSPs. As a result, 10 critical factors and 10 major interactions were identified and further classified into six challenges. Sharing transport schemes, legislative perfection, public private partnership (PPP), and product lifecycle management (PLM) were proposed to govern these challenges. This paper contributes to the existing body of knowledge of bike-sharing programs via a network approach that integrates the key influencing factors with those factors' associated stakeholders. Furthermore, these findings provide the government and operators with implications for mitigating the tough challenges and facilitating the sustainability of DBSPs.uncontrolled parking and waste accumulation are gradually surfacing. These issues are increasingly impeding the future development of DBSPs. Local governments in Beijing, Shanghai and other Chinese cities have forced operators to discontinue the bike-sharing supply programs. In this context, the promise of DBSPs being a means to facilitate sustainable urban travel and reduce carbon emissions is seen as a paradox [5]. How to address these problems is critical to achieve dockless bike-sharing sustainability.In order to address the market failure of DBSPs, the central government of China launched a policy in August 2017. The aim of the policy is to strengthen bicycle-parking management (e.g., the construction of bike lanes and parking spots), implement the real-name system for users registration, and encourage social supervision and public opinion, thus forming a coordinated governance situation among governments, operators, social organizations and the public [6]. Social media and experts have repeatedly called on DBSPs operators to address the bike-sharing issues of waste recycling, deposit refunds and so on. Nevertheless, because dockless bike-sharing programs involve a complex social network, a variety of stakeholders have been influenced, and the interrelationships between them are also complex [7,8]. At this time, there are still no effective measures in place to make the development of DBSPs more sustainable [4].Numerous studies have inves...

With the rapid growth of urban economy and population in China, the output of municipal solid waste (MSW) has dramatically increased becoming a constant threat to residents’ living environment and health. The classification intention of residents plays a pivotal role in solving the problem of MSW disposal. While numerous studies have examined the classification behavior of MSW from the perspective of ordinary residents and households, few studies have attempted to understand young people’s sorting intention. The novelty of this research is to explore the determinants that affect young people’s intention toward municipal solid waste sorting (MSWS) by extending the predictive factors of environmental concern and personal moral obligation into the theory of planned behavior (TPB). A sample of 524 young respondents from Hebei Province in China were used to conduct a structural equation model (SEM) validation. The empirical results revealed that, according to the rankings of significance, personal moral obligation, perceived behavioral control, and subjective norm had positive influences on young people’s intention toward MSWS, while attitude and environmental concern did not. Furthermore, the multi-group comparison showed that, compared with the male and rural group, the intention of female and urban respondents to classify MSW was not affected by subjective norms. Some targeted managerial implications were ultimately proposed to promote young people’s intention toward MSWS. This study contributes to the existing knowledge system of MSWS by revealing the classification intention of young people as a group. The findings and implications provide the government with useful insights for encouraging young people to actively participate in MSWS.

Building information modelling (BIM) is a set of technologies that aim to increase interorganisational and cross-disciplinary collaboration in the architecture, engineering, and construction (AEC) industries to promote productivity and the quality of design, construction, and maintenance stages of a building. Studies on BIM adoption in small and medium-sized enterprises (SMEs) have remained an under-represented area. It is necessary to understand the main challenges hindering the adoption of BIM in SMEs and to consider corresponding strategies that can be applied in order to obtain further understanding of BIM in SMEs. On the basis of literature review and interview, stakeholder-associated factors were identified from a network perspective, and the social network analysis (SNA) method was applied to determine the interconnections between the influencing factors and links in BIM adoption in SMEs. Eventually, 10 critical factors and 10 crucial links were selected and divided into six challenges. Corresponding strategies, including cultivating the BIM perception of SMEs, integrated project delivery, strengthening the legal environment for BIM adoption in SMEs, and developing native software and standards and cloud-based technology, were proposed to mitigate these challenges. The strategies may help practitioners gain an in-depth understanding of BIM adoption in SMEs from a stakeholder-oriented perspective.

In past decades, the massive generation of construction and demolition waste (CDW) was increasingly threatening the public environment and humanity health worldwide. A large amount of research has been devoted to the CDW from difference perspectives. However, few scholars have attempted to summarize and review the extant studies, especially in the managerial areas of CDW (MA-CDW). This paper fills this gap via a systematic and quantitative review in the CDW management field. Employing the scientometric analysis method, a total of 261 articles published from 2006 to 2018 were collected to construct the knowledge map and comprehensive framework for MA-CDW. Results show that the overall evolutionary trend of MA-CDW was from basic management concepts to internal and external challenges analysis, to organizational strategy and innovative management practices. The major MA-CDW knowledge domains were identified and summarized into four pillars, namely: (1) factor and challenge; (2) composition and quantification; (3) assessment and comparison; and (4) technology and method. Based on the trend, knowledge gaps and future research directions were found out and discussed. This study contributes to the existing MA-CDW knowledge by presenting a comprehensive knowledge framework. Furthermore, these findings can provide the researchers and practitioners with an in-depth understanding for the sustainable governance of CDW.

Highlights People’s mask-saving intention in the post-COVID-19 period is first revealed. Integrating TPB and NAM to construct a new and comprehensive theoretical model. Information publicity, environmental concern, subjective norms, person norms, and perceived behavioral control are key drivers. The optimism performance of the mask market and supply chain has not significantly affected people’s saving intention. The publicity for COVID-19 should be effective and appropriate to avoid panic caused by excessive publicity.
