Education, as a key factor in promoting human capital accumulation and social development, has a significant impact on entrepreneurs’ well-being. Based on human capital theory, status attainment theory, and social capital theory, this study utilizes cross-sectional data from the 2021 Chinese General Social Survey (CGSS) to deeply explore the mechanism of how educational attainment affects entrepreneurs’ well-being. The results show that educational level can significantly and directly enhance entrepreneurs’ well-being. Further analysis reveals that educational level influences entrepreneurs’ well-being through three mediating variables: income, perceived social status, and social interaction. Among these, income has a negative impact on entrepreneurs’ well-being, while perceived social status and social interaction have a positive impact. Additionally, the study finds significant differences in the impact of educational attainment on entrepreneurs’ well-being across different age groups, household registration status, and entrepreneurial motivations. These conclusions provide a strong basis for universities to carry out targeted entrepreneurship education and for the government to formulate refined entrepreneurship policies.

Aviation service art and management is a newly added undergraduate major of the Ministry of Education in 2019 which is still in the initial exploration stage. However, the major construction level is related to the quality of talent training and whether it can provide talent support for the high-quality development of China's civil aviation industry. Based on comparative analysis, this paper takes 38 colleges and universities with aviation management major as research objects, reviews the development process of aviation service art and management from two stages, and points out that the lack of national teaching quality standards leads to problems in training objectives, curriculum system and teacher team construction of aviation management. In view of this, this paper puts forward the following suggestions: （1） Appeal to the Ministry of Education to issue the national standards of undergraduate teaching quality suitable for aviation management as soon as possible; （2） According to the adjustment principle of ‘increasing and decreasing’, we should adjust the basic courses of subjects, and continuously strengthen the construction of innovation, advanced and challenging degree of courses; （3） Advocate that school teachers, enterprise teachers, teachers with high academic qualifications and excellent management talents in the industry build a teacher team together; （4） Point out that school-enterprise cooperation can advance to deeper cooperation from three aspects: teaching team building, practice base building and establishment of aviation management committee.

With the continuous improvement of the capital market governance system, it is common for Chinese enterprise managers to use more hidden real earnings management to manipulate earnings, which seriously damages the interests of enterprises and their stakeholders. This paper empirically examines the impact of ESG rating on firms' real earnings management by using Shanghai and Shenzhen A-share listed firms from 2012 to 2023. The results of the study indicate that the ESG rating is negatively correlated with firms' real earnings management, the better the ESG rating of a company, the lower the level of true surplus management. The mechanism analysis shows that ESG can inhibit firms' true surplus management activities by reducing both agency cost and increasing the effect of analyst focus. The research has important reference value for deeply understanding how ESG rating affects the real earnings management behavior of enterprises and promoting the ESG construction of Chinese enterprises.

In order to solve the problem that PCB bare boards were likely to have missed detections and false detections during the small target defect detection process, a PCB bare board defect detection algorithm based on improved YOLOv7, called YOLO-BCN, was proposed. First, the BRA attention mechanism was introduced into the original YOLOv7 backbone network to achieve more flexible computing allocation and content awareness, so that the network had dynamic query-aware sparsity. Then the CARAFE upsampling operator was replaced to extract more shallow features, thereby effectively improving the detection performance of the model for small targets. Finally, the NWD loss function was introduced and combined with IoU to optimize the regression loss function and reduce the sensitivity to small target position deviations. Experimental results show that the mAP@0.5 value and mAP@0.5:0.9 value of the improved YOLOv7 are increased by 3.28% and 2.74% respectively, compared with the original model, the F1 factor is increased by 3.91%, and the detection rate is 46.84 FPS, which effectively improves the accuracy of PCB small target defect detection.

This paper is to develop a novel method for the retrofit of heat exchanger networks by using Heat Exchanger Load Diagram (HELD) after determining energy target and modified path based on Energy Transfer Diagram (ETD) and Bridge Analysis (BA). The aim of the new method is to systematically generate multiple retrofit Heat Exchanger Networks (HENs) of the same quality as far as the minimum energy consumption and the minimum number of heat exchangers are concerned. The concept of cutting point is first proposed and the redistribution of heat load in HENs is realized by moving the stream curve vertically. Combining with heuristics, the number of heat exchangers required in the retrofit HEN is minimized. The HELD of existing HEN is constructed to determine the stream to be moved and the feasible cutting points are selected, and multiple retrofit HENs can be obtained according to the HELD generated by each cutting point, and these solutions are preliminarily compared for further evaluation. In this paper, a milk pasteurization plant is adopted as an example to demonstrate the effectiveness of the proposed method. Four Maximum Energy Recovery (MER) networks with the minimum number of units are obtained, and 395 kW of both hot and cold utility consumption, that is, 26% of cold utility consumption, are saved. Comparing with those reported ones in literature, two new solutions of the same quality are found, and the effectiveness of them is verified.
