摘要：
In this study, we use a dataset collected from eBay to analyze buyers' negative feedback ratings and associated textual comments. By using text mining and sentiment analysis, we identify seven key reasons why buyers post negative ratings: communication problems, shipping issues, product defects, payment refund problems, customer service issues, fraud, and product packaging. These seven reasons can be classified into three categories: (1) sellers' malicious fraudulence toward buyers, (2) factors likely under the control of sellers, and (3) factors not likely under the control of sellers. Drawing on these categories, we discuss how sellers can effectively reduce the likelihood that buyers post negative ratings. The most important things sellers can do to avoid negative ratings are to improve communications with buyers and to handle product shipping issues properly. In addition to posting the reasons for their negative ratings of sellers, the textual comments associated with negative feedback ratings may also include direct denouncements of sellers, such as buyers explicitly claiming a seller is a liar and warning other buyers to be cautious of the seller. We collectively call these actions buyers' denouncements against sellers. These denouncements have significant negative impacts on sellers' reputations. In this study, we use correlation analysis and logistic regression to investigate the factors that motivate buyers to denounce sellers. We find that, of the three categories of reasons why buyers post negative ratings, sellers' malicious fraudulence toward buyers and factors likely under the control of sellers are more likely to lead to buyers' denouncements of sellers, while factors not likely under the control of sellers are not likely to lead to buyers' denouncements of sellers. In addition, buyers' strong negative sentiment is also more likely to lead to their denouncement of sellers. Managerial implications of these findings are discussed.

摘要：
Rapid industrialization in recently industrialized countries (NICs) has exacerbated environmental degradation, raising urgent concerns about how energy consumption, gold prices, and fossil fuel prices contribute to this growing issue. This study aims to evaluate the asymmetric relationships between these factors and environmental degradation across 10 NICs, including Brazil, India, South Korea, Mexico, Indonesia, Turkey, Thailand, South Africa, Malaysia, and the Philippines, from 1995 to 2023. Using the CS-ARDL model, our study demonstrates that while energy costs and renewable energy consumption reduce environmental degradation, gold prices and fossil fuel consumption significantly increase ecological harm. Additionally, the study employs FGLS, CS-DL, AMG, and Driscoll-Kray to verify the robustness of these findings. Notably, the Environmental Kuznets Curve (EKC) hypothesis holds true in these economies. Key results show that a 1 % increase in renewable energy use decreases emissions by 0.7 %, while a 1 % rise in gold prices correlates with a 0.5 % increase in pollution levels. These findings underscore the need for NICs to implement green investments, promote renewable energy, and initiate structural reforms to ensure sustainable development.

摘要：
The "Internet Plus" era has established a closer connection between sports and individuals. This study used data from the 2018 China Family Panel Studies and focused on the middle- and younger-aged population aged 15 to 59 years. Employing a negative binomial regression model, this study empirically analyzed the impact of Internet use on physical exercise and its internal mechanisms among this population. The findings revealed that (1) Internet use significantly promoted physical exercise in the middle- and younger-aged population, with the frequency of physical exercise increasing to 1.549 times the original value; (2) The positive effects of the internet on physical exercise outweighed the negative effects, with online learning and entertainment enhancing physical exercise and online socialization limiting it. Specifically, online learning and entertainment increased the frequency of physical exercise among the middle- and younger-aged population by 0.063 and 0.018, respectively. Online socialization reduced the frequency by 0.023; and (3) The influence of internet use on physical exercise varies; significantly, it positively affects the exercise frequency among individuals over 35 years old and shows a positive correlation with employment status, including both employed individuals and those out of the labor market. The positive role of Internet use in encouraging physical exercise participation among the middle- and young-aged groups should be valued and enhanced.
摘要：
Whether children who inherit social advantages or those who exhibit motivated hard work are more likely to attain superior well-being over time remains a critical question, yet has received little empirical examination. This paper aims to provide new evidence from China on this issue by deploying a natural experiment research design. The empirical analysis explores the link between early-life experiences shaped by parental family background and children's long-term well-being outcome. Using household survey data from China, we find that children born with social advantages tend to complete more years of education in rural areas but fewer years in urban areas compared to their counterparts. Our results are robust to changing the cohort selection, outcome variables, and sources of the analytical sample.

However, there are still some realistic dilemmas in the cultivation of core competencies of college counselors, such as the need to strengthen the understanding of core competencies, the urgent need to improve the career development mechanism, and the need to further improve the level of political literacy. In order to accelerate the cultivation of core competencies of counselors, universities need to build communication platforms, improve the supporting evaluation and employment system, and strengthen theoretical learning, so as to promote the innovative development of ideological and political education in the new era.收起

摘要：
Based on the provincial panel data from 2010 to 2019, taking industrial robots as proxy variables, this paper analyzes the impact of industrial intelligence on industrial structure change through constructing the indicators of optimization, rationalization and synergy of industrial structure and agriculture upgrading, industry upgrading, and service upgrading. Results show that the industrial intelligence has significant effect on the quantity and quality of industrial structure upgrading and the industrial elements synergy, but has no positive effect on the rationalization of industrial structure. Within the industry, it has significantly promoted the upgrading of the automobile industry and the traditional manufacturing industry. It has significantly promoted the transformation of producer services and consumer services, but has no significant impact on the upgrading of agriculture. Further mechanism tests confirm that productivity improvement, capital deepening, labor structure upgrading, industrial spillover and demand traction play mediating roles. Based on the research, policy suggestions are put forward to promote industrial transformation and upgrading.
