With the gradual deterioration of today's ecological environment, there is an urgent need to improve the quality of environmental education. The current environmental education has grown somewhat with the increase in government investment. However older teaching methods seem inadequate to deal with the current situation. The integration of music teaching into environmental education, as explored in this paper, can be a good solution to this problem. This fun and educational approach is a good way to enhance students' interest in learning. After the corresponding discussion on the value of integration, the article used hierarchical analysis to conduct a fuzzy comprehensive evaluation of the combined utility. After stratifying the corresponding influencing factors, the weights were assigned and satisfactory evaluation results were obtained. An example was used for the analysis in this paper. The results showed that third graders with appropriate education got a significant improvement in their scores than sixth graders with no education. Both their median and mean scores improved from 66 and 60 to 70, respectively. More students are also concentrated in the high-score segment. In terms of the direction of focus, the percentages of the four areas of saving food, saving water, saving electricity, and separating garbage all changed. The values of the corresponding numbers for the third and sixth grades are 29%, 20%, 23%, 28% and 29%, 15%, 21%, 35%, respectively.

Probability assessment via expert elicitation or statistical analysis is a critical step in the decision-analysis process. In many actual applications, the number of uncertainties and the corresponding number of assessments can be quite large. In these cases, the analyst may seek guidance in focusing the assessment on the most important uncertainties. In this paper, we develop a novel heuristic that we call the sparse probability assessment heuristic (SPAH). SPAH, which is based on a well-known method in machine learning known as orthogonal matching pursuit, seeks to identify the preferred alternative while conducting the fewest number of assessments. We test SPAH under a variety of conditions and compare its performance to standard practice. In so doing, we show that SPAH is able to identify the optimal alternative while requiring substantially fewer assessments than standard practice.

Abstract
This paper investigates the relation between medical insurance contribution and firm-level total factor productivity in China. Using a sample of Chinese A-share companies from 2007 to 2022, we find robust evidence that firms exhibit lower total factor productivity when medical insurance contribution is increasing. Specifically, we also show that this negative effect is more profound for state-owned enterprises, enterprises with lower employee compensation, and labor-intensive enterprises. Meanwhile, our findings remain valid after a series of robustness tests and controlling for endogeneity. Finally, we propose that the decreasing employees' disposable income is plausible channel through which medical insurance contribution discourages firm-level total factor productivity in China. Overall, these results shed light on the real effects of medical insurance contribution and the determinants of firm-level total factor productivity.
