Workplace ostracism is an essential predictor of knowledge-sharing behaviors, but few studies have explored the influence of this mechanism in higher education. According to the conservation of resources theory, this study elucidated the roles of job burnout and job satisfaction as sequential mediators of the link between workplace ostracism and knowledge-sharing behaviors in a sample of 388 university teachers. The results of the study were analyzed via structural equation modeling (SEM). Higher knowledge-sharing behaviors were associated with lower workplace ostracism, lower job burnout, and more job satisfaction. Furthermore, increased workplace ostracism was associated with more job burnout, but job satisfaction was not related to workplace ostracism. The relationship between workplace ostracism and knowledge-sharing behaviors was mediated by job burnout and was sequentially mediated by job burnout and job satisfaction. These findings help to clarify the mechanisms underlying the association between workplace ostracism and knowledge-sharing behaviors in university teachers. The theoretical and practical implications of the findings are discussed.

Teachers’ voice behaviour has attracted growing attention in universities due to its positive outcomes for institutional reform and improvement. This study investigated how and under what conditions university leaders’ transformational leadership is beneficial to teachers’ voice behaviour using data collected from 434 teachers from universities in China. As a result, we proposed a moderated mediation model of the association between transformational leadership and teachers’ voice behaviour in which group voice climate was used as the mediator and team psychological safety as the moderator. The results revealed evidence of an indirect effect of transformational leadership on teachers’ voice behaviour through the significant mediating role of group voice climate. Moreover, we found evidence that team psychological safety acts as a significant moderator of group voice climate and teachers’ voice behaviour and strengthens the effect of the entire mediating mechanism. Specifically, the mediation effect of group voice climate was significant when team psychological safety levels were at medium or high rather than low levels. Our findings provide a deeper understanding of the benefits and effective mechanism of the impact of transformational leadership on teachers’ voice behaviour in the Chinese university context and offer practical suggestions for facilitating teachers’ voice behaviour in institutions.

BackgroundDelirium is an acute brain dysfunction associated with increased length of hospitalization, mortality, and high healthcare costs especially in patients admitted to the pediatric intensive care unit (PICU). The Cornell Assessment of Pediatric Delirium (CAPD) is a screening tool for evaluating delirium in pediatric patients. This tool has already been used and validated in other languages but not in Italian.ObjectivesTo test the reliability of the Italian version of the CAPD to screen PICU patients for delirium and to assess the agreement between CAPD score and PICU physician clinical evaluation of delirium.MethodsProspective double-blinded observational cohort study of patients admitted to a tertiary academic center PICU for at least 48 h from January 2020 to August 2021. We evaluated intra- and inter-rater agreement using the Intraclass Correlation Coefficient (ICC). The ability of the scale to detect delirium was evaluated by comparing the nurses’ CAPD assessments with the clinical evaluation of a PICU physician with expertise in analgosedation using the area under the ROC curve (AUC).Measurements and Main ResultsSeventy patients were included in the study. The prevalence of pediatric delirium was 54% (38/70) when reported by a positive CAPD score and 21% (15/70) when diagnosed by the PICU physician. The CAPD showed high agreement levels both for the intra-rater (ICC 1 0.98, 95% CI: 0.97–0.99) and the inter-rater (ICC 2 0.93, 95% CI: 0.89–0.96) assessments. In patients with suspected delirium according to the CAPD scale, the observed sensitivity and specificity of the scale were 0.93 (95% CI: 0.68–1.00) and 0.56 (95% CI: 0.42–0.70), respectively. The AUC observed was 0.75 (95% CI: 0.66–0.8490).ConclusionThe Italian version of the CAPD seems a reliable tool for the identification of patients at high risk of developing delirium in pediatric critical care settings. Compared to the clinical evaluation of the PICU physician, the use of the CAPD scale avoids a possible underestimation of delirium in the pediatric population.
