Waste generation and disposal have been a global issue for decades. The total global greenhouse gas (GHG) emissions in 2019 were 49,758 MtCO2e with waste disposal accounting for 3.2%. With rapid urbanization trends, municipal solid waste (MSW) has become a global challenge which needs to be addressed. A large fraction of MSW such as food wastes, e-waste among others still ends up with unregulated dumps or openly burned in low-income countries. As a response, China initiated the ‘zero-waste’ pilot program which has been running since 2019. To investigate the potential contribution of MSW management to GHG reductions, this study selected four ‘zero-waste’ cities in China, namely Shenzhen, Panjin, Xining and Tongling, as case studies to assess the impacts of different MSW management policies on GHG reductions from 2015 to 2019. Results demonstrated that Shenzhen city achieved progress in reducing GHGs, which decreased by more than 40% between 2015 and 2019. This study provides policy recommendations and waste management approaches and practices to optimize MSW management and reduction of GHGs.

To reduce the drug resistance of bacteria and enhance the antibacterial ability in bacterial infection therapy, we designed a new antibacterial nanoagent. In this system, a photosensitizer (indocyanine green, ICG) was loaded in bovine serum albumin (BSA) through hydrophobic-interaction-induced self-assembly to form stable BSA@ICG nanoparticles. Furthermore, a positively charged antibacterial peptide bacitracin (Bac) was physically immobilized onto the surface of BSA@ICG to generate a bacterial-targeted nanomedicine BSA@ICG@Bac through electrostatic interactions. Afterward, its photodynamic and photothermal activities were intensely evaluated. Moreover, its bactericidal efficiency was assessed

Pedestrian vehicle conflicts at non-signalized crosswalks are a world-wide safety concern. Although the "pedestrian priority" policy is applied in some regions to improve pedestrian safety, its effect needs further investigation. This study proposes the Lane-based Distance-Velocity model (LDV) to investigate pedestrian-vehicle interaction at non-signalized crosswalks. Compared with the DV model, the LDV model considers the lateral distance between vehicles and pedestrians. Therefore, the LDV model extends the application of the DV model by allowing it to be applied not only on one-lane streets to multi-lane streets. The conflict severities of pedestrian-vehicle interaction in the LDV model are classified into four categories: safe-passage, mild-interaction, potential-conflict and potential-collision. Based on that, pedestrian crossing decisions are graded as safe-crossing, risky-crossing, and dangerous-crossing. The experimental data are collected at a non-signalized crosswalk through drone footage collected in Xi'an City (China) with a Machine Vision Intelligent Algorithm. The model is tested through a case study to evaluate pedestrian crossing safety when interacting with private cars and taxis. Results from the case study suggest that the proposed model works well in the pedestrian-vehicle interaction analysis. Firstly, 87.9% of drivers are willing to provide right-of-way to pedestrians when they have enough time to react and yield. Then, both the DV model and LDV model have reached consistent conclusions: the deliberate violation rate (DVR) of taxi drivers is 22.64%, which is double that of private car drivers. Last, taxis commit a higher percentage of pedestrians' dangerous or risky crossing situations than private cars. Relevant government departments can utilize the results of this study to manage urban traffic better and improve pedestrian safety.

In the 21st century, technology and financial innovation are inseparable. The financial industry is undergoing a new change: the Internet, and the "green digital finance" which follows the pace of the world's "green finance" is also beginning to appear in front of the public.

The zero-fare tour is a common phenomenon in China that receives a great deal of attention from the popular press but little attention in the tourism literature. This qualitative study illuminates the previously unheard voice of the zero-fare group tour guides, examining their work attitudes and relationships with tourists, tour operators, and tourism administrators. A two-phase pre- and post-interview approach is used to examine the impacts of the 2013 tourism law on the tour guides. Findings indicate that tour guides struggle with conflicting feelings towards the zero-fare tour and their place within it. For instance, the informants describe themselves as scapegoats of the zero-fare tour mode, yet they also enjoy the freedom and opportunity it presents. The study concludes with a call for more thoughtful consideration of the policy and governance of the zero-fare tour.

Purpose – The study aims to explore the expectations and perceptions of corporate social responsibility (CSR) strategies among Chinese fast-food diners, and to investigate the relationships among CSR strategies, consumer satisfaction and customer loyalty behaviors. Chinese diners’ knowledge about a real world brand’s CSR activities was also investigated. Design/methodology/approach – Setting the research context on the fast food industry in China and selecting McDonald’s as the subject brand, a survey study was conducted in a Southern Chinese mid-scale city. A convenience sample of 320 was withdrawn, and the data were analyzed with SPSS 18.0. Findings – Results from the study show that the Chinese fast food diners expect restaurant companies to attach more importance to “(product) nutrition and well-being (of customers)” and “environment sustainability” to be considered socially responsible. CSR performance was found to be the most influential factor in the consumers’ loyalty behaviors compared to customer satisfaction with service, product and the total visit experience. The study also found that many of McDonald’s CSR activities were unknown to the Chinese respondents. Originality/value – China is an attractive market to most global companies including fast food chain companies. Understanding Chinese diners’ expectations and perceptions toward companies’ CSR strategies will contribute to the success rate of companies operating in China. In addition, by using a real-world brands as the research context, the study tries to avoid perception bias of respondents due to the different interpretations of CSR in different organizations and industries.

This study attempts to segment Chinese tourists visiting the US based on items representing motivations. A factor-cluster approach was used to analyze the data. Factor analysis resulted in six underlying motivation factors: Relaxation/Escape, Prestige, Knowledge, Job Fulfillment, Entertainment, and Novelty. Based on the six motivation factors, cluster analysis identified three homogeneous groups of respondents. The distinct groups were identified as High Brow Traveler, Enthusiastic Traveler, and Reluctant Traveler. Marketing implications were provided based on the findings.

The article focuses on the influence of acculturation on the dining-out behavior of Chinese people in the United States. A popular acculturation scale, Acculturation Rating Scale for Mexican Americans (ARSMA), was adapted and applied to the Chinese population in a college town in New England. Then, the sample was grouped into clusters based on the three types of assimilation (i.e., integration, identification, and acculturation) and their dining-out behavior was examined across the groups. The results showed that the type of assimilation and acculturation did have some impact on dining-out behavior.
