  • Analysis and recommendations for energy conservation and carbon emission reduction in industry boosted by digital energy management systems

    Subjects: Statistics >> Social Statistics submitted time 2024-03-27 Cooperative journals: 《中国科学院院刊》

    Abstract: Energy consumption during production processes in the industry is a main source of carbon dioxide emissions. Therefore, for China’s dual-carbon goals, industrial enterprises need to focus on reducing energy waste to achieve energy-efficient production, thereby effectively reducing carbon emissions in industrial production. In recent years, with the continuous development and popularization of digital technology, digital energy management systems have played a crucial role in energy saving by visualizing invisible energy in the industry. In this context, this study first analyses the current status of digital energy management system applications in the UK, the US, Germany, and Sweden, summarizes their characteristics and conditions, and compares the differences between China’s energy management system development and other countries’. Furthermore, this study explores the challenges faced by the government, technology, and enterprises in promoting the deployment of energy management systems in Chinese industrial enterprises. Next, the study proposes to analyse energy consumption from the perspective of product rather than factory, production lines, or machines. The concept of “unit product energy consumption label based on production steps” is defined, and a methodological framework for digital energy consumption data analysis based on this label is constructed. This study further discusses the roles of the major stakeholders, including governments, enterprises, digital energy management system technology providers, certification bodies, etc., in achieving standardization and unified analysis of energy consumption labels and puts forward suggestions for the government to develop digital energy management systems in the industry to reduce carbon emissions. The suggestions include: continuing to promote the construction of energy management systems in enterprises; continuously supporting the cooperative development among various stakeholders; gradually determining energy consumption benchmarks by product and production steps; and actively leading enterprises to benchmark industry best practices.

  • The Impact of Conflicting Health Information in Consumers’ Health Information Seeking: An Investigation of Uncertainty

    Subjects: Library Science,Information Science >> Information Science submitted time 2023-04-01 Cooperative journals: 《图书情报工作》

    Abstract: [Purpose/significance] Recently, health information has become prevalent on the Internet. The extensive information volume and heterogeneity in information quality increased the probability of encountering conflicting information in users’ health information seeking. However, it has been insufficiently explored how conflicting health information may impact users. This study departs from the relationship between information seeking and uncertainty reduction, as indicated by many classic information behavior theories. We raised a research question of whether the hypothesized relationship still stands in conflicting health information contexts. [Method/process] By employing the experimental approach and one-way analysis of variance (ANOVA), we examine the effects of conflicting health information on individuals regarding knowledge states, confusion, and health beliefs. [Result/conclusion] The results suggested that conflicting health information blurred knowledge states, increased confusion, and decreased health belief. Thus, we inferred that uncertainty increased when they encountered conflicting health information. Based on the results, several theoretical and practical implications were discussed.

  • Research on Influencing Factors of Online Surrogate Health Information Seeking: Based on the Health Belief Model and Social Support Theory

    Subjects: Library Science,Information Science >> Information Science submitted time 2023-04-01 Cooperative journals: 《图书情报工作》

    Abstract: [Purpose/significance] Online surrogate health information seeking is an everyday life information practice mode based on interpersonal cooperation. It is of great significance of deeply understanding the information behaviors to explore the influencing factors and mechanisms of this behavior based on the classical theories. [Method/process] Based on the health belief model and social support theory, this paper constructed the influencing factors model of surrogate health information seeking and put forward 12 research hypotheses. 475 valid data were collected through questionnaire survey and analyzed by SmartPLS. [Result/conclusion] The results show that empathy, information support intention, perceived severity and perceived benefits have positive impact on online surrogate health information seeking intention (OSHISI), while perceived barriers have a negative impact on OSHISI. Perceived susceptibility and self-efficacy have no direct relationship with OSHISI. The mediating effect analysis showed that the relationship between perceived susceptibility and OSHISI is completely mediated by empathy. Empathy plays a partial mediating role in the relationship between perceived severity and OSHISI. The relationship between self-efficacy and OSHISI is partially mediated by information support intention. The results of this study provide a reference for further motivating, managing and intervening online surrogate health information seeking practices.
