Field research limits the possibility of clarifying the current food waste situation in China. Material flow analysis was used to assess the magnitude and characteristics of waste in five stages from 2010–2019 by seven selected types. Wheat was wasted the most at 38%, while milk was wasted the least at 4%. During post-harvest handling and storage, processing and packaging, and consumption, wheat was wasted the most (56%, 36%, and 48%), while during production and marketing, tomatoes were wasted the most (28% and 25%). Wheat, apples, tomatoes, pork, and milk were wasted the most in consumption, while soybeans were wasted the most in processing and packaging, and freshwater fish were wasted the most in production. A scenarios hypothesis proved that a 5% reduction in each stage would reduce import demand for soybeans by 7%. This study provides a data reference and theoretical basis for food waste intervention and food security strategies.

A personal norms intervention strategy is an effective way to reduce food waste behavior. However, the mechanism controlling how personal norms affect food waste behavior needs to be further investigated. In addition, previous studies have reported that weight control is part of this mechanism, but few studies have focused on how internal (personal norms) and external beauty (weight control) act simultaneously on individuals. This study constructed an analytical framework with personal norms as the independent variable, emotions as the mediating variable, and weight control as the moderating variable from a cognitive perspective. A stratified regression approach was used to analyze 835 validated questionnaires on food waste at the consumption level (outside the home) that were collected from across China. The results showed that (1) Chinese consumer personal norms about eating at restaurants and outside the home exacerbated food waste behavior; (2) consumer emotions mediated the effect of personal norms on food waste behavior; and (3) weight control moderated both paths associated with the mediating effect of emotions, and its cubic term had a more significant moderating effect. Policy recommendations are proposed based on the conclusions of this study that will effectively reduce food waste behavior.

Protecting labor safety and health and actively carrying out occupational safety and health management (OSHM) is a common need worldwide, and it is also one of the important efforts of Chinese enterprises under the background of promoting the implementation of the Healthy China strategy. Based on in-depth thinking on the current stage of OHSM, this study incorporated “management framework, management process, management effectiveness” (FPE) into an integrated framework and constructed an FPE evaluation system for enterprise OHSM. This study innovatively collected and refined FPE information from the perspective of information disclosure and used the combined weight cloud model to evaluate the occupational health and safety management level (OHSML) of 69 listed companies in China’s energy industry from 2009–2019. The results showed the following. (1) The OHSML of most listed companies in China’s energy industry was still at a low-end level. Among the companies that have issued relevant information reports, only 5.58% (S = 30) of the sample companies’ OHSML were at an acceptable level (Level IV) or declarable level (Level V). The OHSML comprehensive evaluation level of 92.56% (S = 498) of the sample companies was between the transitional level (Level III) and the improved level (Level II). (2) During 2009–2019, although the annual OHSML of listed companies in China’s energy industry showed an upward trend, the growth rate was low, and even the OHSML of some listed companies in the energy industry showed the characteristics of reduced fluctuations. (3) From the perspective of the PFT three-dimensional subsystem level of OHSM, the evaluation level of the governance framework subsystem was the highest, whereas the evaluation level of the management process subsystem and the management effectiveness subsystem were relatively low. Finally, according to the relevant results, some suggestions were proposed to improve the OHSML of listed companies in China’s energy industry. These findings can provide guidance for companies to improve their OSHM performance.

This paper presents high school students’ sense-making of Artificial Intelligence (AI) and Machine Learning (ML) before and after they participated in a three-week technology-enhanced AI curriculum experience. We analyzed students’ pre-and-post assessment responses, responses to activity-specific questions, and classroom video recordings to explore their understanding of AI and ML. Our analysis revealed that students’ AI and ML conceptions shifted from media-informed concepts and presuppositions to more structured and process-oriented understandings after they completed AI curriculum modules. Our ongoing and future work aims to develop a deeper understanding of how students’ sense-making of AI and ML is influenced by their prior knowledge, experiences, and perspectives as well as the curriculum activities, tasks, and resources.

Non-green labor patterns have a negative impact on health and organizational sustainable development. This research proposes a green labor style that takes the sustainable development of employees themselves as the premise, with the protection of their physical and mental health as a long-term goal, that is not only concerned with how to build a reasonable mechanism to guarantee the physical and mental health of employees, but also with the labor protection mechanism of the whole process, from production to output. On the basis of social cognitive theory and the job demands-resources (JD-R) model, this study recruited a sample of 884 Chinese employees to explore the mechanism of their willingness to conduct green labor, including factors such as institutional constraints, boundary management, and organization-based self-esteem (OBSE). The results show that high levels of institutional constraints curbed employee demand for green labor and, in employees, good boundary-management skills acted as a mechanism of resistance against negative constraints. Furthermore, individual OBSE, as a positive psychological resource, could buffer the negative impacts of the organizational scenarios on outcomes.
