In this study, a system dynamics (SD) model is developed to guide the subsidy policies to promote the diffusion of green supply chain management (GSCM) in China. The relationships of stakeholders ...such as government, enterprises and consumers are analyzed through evolutionary game theory. Finally, the GSCM diffusion process is simulated by the model with a case study on Chinese automotive manufacturing industry. The results show that the subsidies for manufacturers are better than that for consumers to promote GSCM diffusion, and the environmental awareness is another influential key factor.
Green Public Procurement (GPP) is an increasingly debated “demand side” environmental policy instrument. The aim of this paper is to take stock of the related literature, with the twofold aim of ...developing a conceptual model of the relevant phases of GPP and to identify the related research gaps in detail. The literature analyzed here comprises English language papers, which are focused on GPP during the time period from 2000 to 2016. By means of a systematic literature review and content analysis, we provide both a quantitative and qualitative viewpoint. As our analysis reveals, GPP discussion has mostly focused so far on the specific impacts of GPP implementation, while the discussion on GPP as compared to other environmental policy tools, in terms of efficiency and innovation, is still lagging behind; this is coupled with a limited geographical coverage. Finally, by disaggregating the 17 years period under scrutiny into four sub-periods allows us to outline the changes in research trends over time.
•We develop an innovative critical review on Green Public Procurement.•We focus on the period 2000–2016, and adopt a content analysis method.•The literature is increasingly focused on environmental performances.•The field of GPP is under-theorized in terms of its efficiency properties.•More attention on the link between GPP and eco-innovation is needed.
Corporate social responsibility (CSR) in supply chain management (SCM) has gained an increasing research attention in recent years. Extant studies have discussed stakeholder interests, performance ...evaluation, ethical sourcing, and sustainable production. The purpose of this paper is to develop a systematic study quantitatively depicting the knowledge structure and the intellectual progress of CSR for SCM. This research adopts bibliometric analysis in conjunction with network analysis to systematically evaluate the CSR-related publications for SCM. The analysis involves 628 peer-reviewed articles identified with careful selection of influential work. Data analytic techniques including citation analysis, co-citation analysis and co-word analysis are used. Key findings for researchers include (1) an analytical discussion of the five sub-fields that constitute the intellectual structure of CSR for SCM; (2) Theoretical and conceptual research significantly dominate in this field; (3) The topics of sustainable development and economic and social effects are more frequently discussed among scholars; (4) Key research gaps include lacking of practical and normative modeling research, and considering from the supplier perspectives in emerging economies. The findings suggest that future research would emerge a greater depth of practical and modeling analysis to enrich the theories.
•We review 548 papers in the field of corporate social responsibility (CSR) for supply chain management (SCM).•The sub-fields and their relationships constituting the intellectual structure of CSR for SCM is delineated.•Pivotal works in establishing foothold in the domain are identified.•Maps to illustrate the different topic areas of current interests are depicted.•Future research directions encompassing practical and research fields are proposed.
Green supply chain management (GSCM) has gained increasing attention within both academia and industry. As the literature grows, finding new directions by critically evaluating the research and ...identifying future directions becomes important in advancing knowledge for the field. Using organizational theories to help categorize the literature provides opportunities to address both the objectives of understanding where the field currently stands and identifying research opportunities and directions. After providing a background discussion on GSCM, we categorize and review recent GSCM literature under nine broad organizational theories, with a special emphasis on investigation of adoption, diffusion and outcomes of GSCM practices. Within this review framework, we also identify GSCM research questions that are worthy of investigation. Additional organizational theories which are considered valuable for future GSCM research are also identified with a conclusion for this review.
Purpose - The rapid development of Web 2.0 and social media enables the rise of crowdsourcing. Crowdsourcing contest is a typical case of crowdsourcing and has been adopted by many organisations for ...business solution and decision making. From a participant's perspective, it is interesting to explore what motivates people to participate in crowdsourcing contest. The purpose of this paper is to investigate the category of motivation based on self-determination theory and synthesises various motivation factors in crowdsourcing contest. Meanwhile, perceived motivational affordances and task granularity are also examined as the moderate constructs. Design/methodology/approach - The paper builds a conceptual model to illustrate the relationships between various motivations (extrinsic and intrinsic) and participation effort under the moderating of perceived motivational affordances and task granularity. An empirical study is conducted to test the research model by surveying the Chinese participants of crowdsourcing contest. Findings - The results show that various motivations might play different roles in relating to participation effort expended in the crowdsourcing contest. Moreover, task granularity may positively moderate the relationship between external motivation and participation effort. The results also show that supporting of a participant's perceived motivational affordances might strengthen the relationship between the individual's motivation with an internal focus (intrinsic, integrated, identified and introjected motivation) and participation effort. Originality/value - Overall, the research has some conceptual and theoretical implications to the literature. This study synthesises various motivation factors identified by previous studies in crowdsourcing projects or communities as a form of motivation spectrum, namely external, introjected, identified, integrated and intrinsic motivation, which contributes to the motivation literatures. Meanwhile, the findings indicate that various motivations might play different roles in relating to participation effort expended in the crowdsourcing contest. Also, the study theoretically extends the crowdsourcing participation research to incorporate the effects of perceived motivational affordances in crowdsourcing contest. In addition, the study may yield some practical implications for sponsors, managers and designers in crowdsourcing contest.
Background
Diabetes has become one of the most prevalent chronic diseases, and many people living with diabetes use social media to seek health information. Recently, an emerging social media app, ...TikTok, has received much interest owing to its popularity among general health consumers. We notice that there are many videos about diabetes on TikTok. However, it remains unclear whether the information in these videos is of satisfactory quality.
Objective
This study aimed to assess the quality of the information in diabetes-related videos on TikTok.
Methods
We collected a sample of 199 diabetes-related videos in Chinese. The basic information presented in the videos was coded and analyzed. First, we identified the source of each video. Next, 2 independent raters assessed each video in terms of the completeness of six types of content (the definition of the disease, symptoms, risk factors, evaluation, management, and outcomes). Then, the 2 raters independently assessed the quality of information in the videos, using the DISCERN instrument.
Results
In regard to the sources of the videos, we found 6 distinct types of uploaders; these included 3 kinds of individual users (ie, health professionals, general users, and science communicators) and 3 types of organizational users (ie, news agencies, nonprofit organizations, and for-profit organizations). Regarding content, our results show that the videos were primarily about diabetes management and contained limited information on the definition of the disease, symptoms, risk factors, evaluation, and outcomes. The overall quality of the videos was acceptable, on average, although the quality of the information varied, depending on the sources. The videos created by nonprofit organizations had the highest information quality, while the videos contributed by for-profit organizations had the lowest information quality.
Conclusions
Although the overall quality of the information in the diabetes videos on TikTok is acceptable, TikTok might not fully meet the health information needs of patients with diabetes, and they should exercise caution when using TikTok as a source of diabetes-related information.
Accounting for 7% of energy consumption from all industrial sectors and 15% of total greenhouse gas (GHG) emissions in China in 2009, the cement industry should be one of the main sectors to ...implement low carbon development. However, a detailed study on presenting its GHG emission trajectory and identifying the key driving factors has yet to be done. Under such a circumstance, this paper first presents a GHG emission inventory of the cement industry in China and then identifies the main driving factors that influence changes of GHG emissions in the cement industry by adopting LMDI method. Our results show that the total GHG emission in 2009 was 1095.1 Mt carbon dioxide equivalent (CO2e), of which 592.8 Mt CO2e was process-related and 502.3 Mt CO2e was energy-related. The major factors responsible for the increase of GHG emissions during 2005–2009 include cement production activity effect and clinker production activity effect, while energy intensity effect played a positive role to offset total GHG emissions. Finally, we present our policy implications and provide possible technical solutions for reducing GHG emissions of the cement industry in China.
•The cement industry is one key sector to implement low carbon development in China.•LMDI method was used to quantify the main driving factors on GHG emissions in the cement industry.•Process-related GHG emission is 592.9 Mt CO2e and energy-related GHG emission is 501.5 Mt CO2e.•Cement production activity effect and clinker production activity effect are the key driving forces.
Chronic obstructive pulmonary disease (COPD) has become one of the most critical public health problems worldwide. Because many COPD patients are using video-based social media to search for health ...information, there is an urgent need to assess the information quality of COPD videos on social media. Recently, the short-video app TikTok has demonstrated huge potential in disseminating health information and there are currently many COPD videos available on TikTok; however, the information quality of these videos remains unknown.
The aim of this study was to investigate the information quality of COPD videos on TikTok.
In December 2020, we retrieved and screened 300 videos from TikTok and collected a sample of 199 COPD-related videos in Chinese for data extraction. We extracted the basic video information, coded the content, and identified the video sources. Two independent raters assessed the information quality of each video using the DISCERN instrument.
COPD videos on TikTok came mainly from two types of sources: individual users (n=168) and organizational users (n=31). The individual users included health professionals, individual science communicators, and general TikTok users, whereas the organizational users consisted of for-profit organizations, nonprofit organizations, and news agencies. For the 199 videos, the mean scores of the DISCERN items ranged from 3.42 to 4.46, with a total mean score of 3.75. Publication reliability (P=.04) and overall quality (P=.02) showed significant differences across the six types of sources, whereas the quality of treatment choices showed only a marginally significant difference (P=.053) across the different sources.
The overall information quality of COPD videos on TikTok is satisfactory, although the quality varies across different sources and according to specific quality dimensions. Patients should be selective and cautious when watching COPD videos on TikTok.
The rapidly growing industrial activities in emerging economies such as China have been causing resource depletion and pollution problems. This reality requires China to adopt an integrated ...management approach to resolve the conflict between industrial development and environmental protection, and the concept of circular economy (CE) serves this purpose. In this paper, we examine if different types of manufacturing enterprises on environmental-oriented supply chain cooperation (ESCC) exist. We also determine if the Chinese manufacturer types varying in ESCC differ in their implementation of the CE practices towards achieving the CE-targeted goals on improving both environmental and economic performance. Our cluster analytic results with multivariate analysis of variance (MANOVA) among the four identified types of Chinese manufacturers varying in environmental-oriented supply chain cooperation highlight the importance to intensify the cooperation with upstream and downstream supply chain partners for a CE initiative to succeed.
