RESUMEN
Residents of the United States and China have responded very differently to the implementation of COVID-19 preventive measures. This study introduces the uncertainty reduction theory and the need for cognitive closure (NFC) framework into the context of a public health crisis and compares models across the United States and China. Specifically, we collected survey data to examine how NFC, trust in government, and attitudes toward preventive measures predicted pandemic compliance behaviors, depressive symptoms, and life satisfaction among 745 college students (399 from China and 346 from the United States). Chinese participants trusted their government more, believed COVID preventive measures to be more beneficial, and reported more pandemic compliance and fewer depressive symptoms than U.S. PARTICIPANTS: Trust in government and attitudes towards preventive measures mediated the relationships between NFC and pandemic compliance behaviors among Chinese participants but not U.S. PARTICIPANTS: NFC predicted better mental health outcomes among participants in China compared to U.S. PARTICIPANTS: Trust in government mediated NFC and mental health outcomes among Chinese participants. Trust in government predicted better mental health (fewer depressive symptoms and more life satisfaction) in both the United States and China. Theoretical and practical implications of these findings for promoting mental health and pandemic compliance behavior during the COVID-19 pandemic are discussed.
RESUMEN
Taking both individual and team levels into consideration has been called for years in terms of research on leadership. Inclusive leadership, a trending leadership style emerging from the global needs of managing the increasingly diversified workplace nowadays, has yet been rarely studied at both levels. To answer these calls, we specifically analyzed the relationship between inclusive leadership, team psychological safety, and innovative performance via a multilevel analysis. The results are based on a study of 356 employees from 90 working teams. Individual perceptions of inclusive leadership are positively related to the individual innovative performance through the mediation of individual psychological safety. Team perceptions of inclusive leadership are positively related to the team innovative performance through the mediation of team psychological safety. Moreover, team perceptions of inclusive leadership are positively related to the individual innovative performance through the cross-level mediation of individual psychological safety. Implications for both theory and practice are discussed.
RESUMEN
Background: An increasing number of geriatric patients are suffering from degenerative lumbar spondylolisthesis (DLS) and need a lumbar interbody fusion (LIF) operation to alleviate the symptoms. Our study was performed aiming to determine the predictors that contributed to unfavorable clinical efficacy among patients with DLS after LIF according to the support vector machine (SVM) algorithm. Methods: A total of 157 patients with single-segment DLS were recruited and performed LIF in our hospital from January 1, 2015 to October 1, 2020. Postoperative functional evaluation, including ODI and VAS were, performed, and endpoint events were defined as significant relief of symptom in the short term (2 weeks postoperatively) and long term (1 year postoperatively). General patient information and radiological data were selected and analyzed for statistical relationships with the endpoint events. The SVM method was used to establish the predictive model. Results: Among the 157 consecutive patients, a postoperative unfavorable clinical outcome was reported in 26 patients (16.6%) for a short-term cohort and nine patients (5.7%) for a long-term cohort. Based on univariate and multivariate regression analysis, increased disc height (DH), enlarged facet angle (FA), and raised lateral listhesis (LLS) grade were confirmed as the risk factors that hindered patients' short-term functional recovery. Furthermore, long-term functional recovery was significantly associated with DH alone. In combination with the SVM method, a prediction model with consistent and superior predictive performance was achieved with average and maximum areas under the receiver operating characteristic curve (AUC) of 0.88 and 0.96 in the short-term cohort, and 0.78 and 0.82 in the long-term cohort. The classification results of the discriminant analysis were demonstrated by the confusion matrix. Conclusions: The proposed SVM model indicated that DH, FA, and LLS were statistically associated with a clinical outcome of DLS. These results may provide optimized clinical strategy for treatment of DLS.
