The topic of teacher work satisfaction has long been a focus of educational study. This study examined the impact of school organizational support on teacher job satisfaction as mediated by teachers’ engagement in educational research, utilizing the findings of a survey on the academic quality of basic education students in Jiangsu Province in 2020 and analyzing the data of 21,154 primary and 16,585 secondary school teachers. In this work, the structural equation model is utilized. Significant favorable relationships are shown between school organization support, teachers’ participation in educational research, and teachers’ work happiness.

School organization support positively predicts teacher job satisfaction. The impact of school organization support on teachers’ participation in educational research and job satisfaction is greater at the primary level than at the junior secondary level

Specification of Sulfur Forms in Coal

Over a century of studies of the organic chemistry of coal has led to many accomplishments in coal chemistry. The recognition of the role that sulfur plays in coal makes the speciation of sulfur in coal one of the most important research goals. In this research solvent extraction, ultimate analysis, FTIR, TG-FTIR, sulfur methylation, and NMR techniques were employed to make quantitative and qualitative determinations of the organic sulfur in coal and its extracts. The data obtained from those methods are discussed with regard to the analytical and synthetic approaches used. Carbon-sulfur bond cleavage at room temperature was observed during this research and was verified using reactions of model compounds
