In recent years, with the unremitting advancement of higher education reform, academics have been experiencing stress associated with conducting scientific research. In this study focusing on ...university teachers in China, we adopted a stepwise regression method and reviewed related literature to construct a mechanism of academic stress and occupational burnout. Specifically, we tested job satisfaction and relative deprivation as mediating and moderating variables and conducted empirical research on 1239 teachers from 15 universities in eastern, central, and western China. Our findings show that: (1) academic stress has a significant positive effect on occupational burnout; (2) job satisfaction has a partial role as the intermediary agent between academic stress and occupational burnout; and (3) relative deprivation positively moderates the relationship between academic stress and job satisfaction, indicating that teachers in universities and colleges are also affected by relative deprivation and the perception of inequity. These findings have significant value in the management of higher education and academic research.
This article introduces the new family of living radical polymerizations with germanium (Ge), tin (Sn), phosphorus (P), and nitrogen (N) catalysts which we recently developed. The polymerizations are ...based on a new reversible activation mechanism, Reversible chain Transfer (RT) catalysis. Low-polydispersity polymers are obtained in the homopolymerizations and random and block copolymerizations of styrene, methyl methacrylate, and functional methacrylates. The background, performance, and kinetic features of the polymerizations are described. Attractive features of the catalysts include their high reactivity, low toxicity (Ge, P, and N), low cost (P and N), and ease of handling (robustness).

Literary history and libraries’ progress are evident of women professionals’ contributions. Since the beginning, women professionals’ roles and responsibilities in different capacities have been ...quite phenomenal. The present study highlights the contributions published in the Journal of Documentation for the period 2015-2019. It attempts to study the variations existing in research output from a gender perspective and a brief review of women professionals’ journey and job-related aspects from traditional to contemporary times. The information is collected from the Journal of Documentation (JoD). The study focuses on the year-wise distribution of articles and authors, collaboration patterns among the gender, authorship pattern, geographical distribution, the annual growth rate of female contributors, and average productivity of male and female authors per article. The findings revealed that the annual growth rate of the female contributors was 28.6 in 2019. The male author’s average productivity per article is 1.23, and 1.12 is the female contributors’ average productivity per paper. The study is beneficial in understanding the women’s contributions in international journals, and it has also revealed that the publication gap is not huge. Still, it is minimal except in a few circumstances.
The corrosion and inhibition behaviors of mild steel in aerated sulphuric acid in the presence of propargyl alcohol (PA) and potassium iodide (KI) were investigated using electrochemical methods. It ...was found that the inhibition efficiency increased with PA concentration, but the potential of unpolarizability (
E
u), which indicates the commencement of desorption of adsorbed propargyl alcohol on the electrode, remained unchanged with increasing PA concentration. The addition of potassium iodide in the solution increased the value of
E
u. A synergistic effect was observed between KI and PA with an optimum mass ratio of PA/ KI=1/1. The experimental results suggest that the presence of iodide ions in the solutions stabilized the adsorption of PA molecules on the metal surfaces and, therefore, improved the inhibition efficiency of PA. In the solutions containing propargyl alcohol (PA), the
E
u values remained unchanged with increasing immersion times, indicating that there was less possibility of polymerization of PA molecules. An adsorption mechanism was favored for the inhibition of PA.
