The Harman single-factor test was employed to examine potential common method bias, which refers to the distortion of results due to using a single data source or measurement method. In our exploratory factor analysis, 12 eigenvalues exceeded 1, with the first factor explaining 23.63% of the variance, well below the 40% threshold that would indicate significant common method bias. Therefore, our analysis does not suffer from significant common method bias.

AbstractLet G be a finite group and G be a split extension of A by B, that is, G is a semidirect product: \(G=A\rtimes B\), where A and B are subgroups of G. Under the condition that B permutes with every maximal subgroup of Sylow subgroups of A, every maximal subgroup of A or every nontrivial normal subgroup of A, we prove that the supersolvable residual of G is the product of the supersolvable residuals of A and B.

This study analyzed 2088 college students from five universities between September, 2021 and May, 2023. We recruited college students who volunteered to participate in a survey. The survey included questions about participants’ basic demographics, exercise and eating habits, lifestyle, sleep quality, and mental health status [17]. The questionnaire was presented in Chinese, and the same language versions questionnaires applied uniformly on all participants.

Many studies have shown ESEM, rather than CFA, may often be more applicable when model testing for data fit [56]. Some researchers have argued that the ESEM model is better able to describe the data, and the results of the current study lend further support to this claim. This study examined the validity and reliability of the Chinese version of the DASS-21 in Chinese left-behind children.

AbstractThis paper presents a predator–prey fishery model with impulsive effects, which considers transient/nontransient pulse birth and introduces the harvesting and releasing of the prey fish population at different fixed moments of time. We prove that all solutions of the investigated system are uniformly ultimately bounded.
