AbstractPurpose -The purpose of this paper is to discover and better understand the efficiency of university mergers from the perspective of knowledge production, with the research capability as the point of contact. Design/methodology/approach -In total, 20 colleges and universities directly under the central ministries that merged in 2000 were taken as the research samples. Factor analysis methods are adopted to calculate the public factor scores, which were taken as the basis of the time series analysis and similar comparative analysis. Findings -The results indicated that, by the end of 2005, the reform of universities merger has a positive impact on the universities' knowledge production, but there was a "short-term prosperity" after the merger happened, especially in the aspect of scientific research funding efficiency and the transformation of knowledge production outcomes. Originality/value -Few if any mergers are painless and in the literature on mergers it is generally agreed that it can take up to ten years for the wounds to heal and for the new institution forged from previously autonomous identities to operate as a cohesive and well integrated whole.

PurposePrincipal leadership is an important external environmental factor that affects and alleviates teachers' job burnout. The purpose of this paper is to explore the deep internal mechanisms of the influence of principal transformational leadership on teacher job burnout in the context of Chinese teachers.Design/methodology/approachA cluster sampling method was used to conduct a questionnaire survey on 990 elementary school teachers in 14 primary schools in Beijing. This study uses a structural equation model to analyze the chain intermediary effect of social-emotional competence and the student-teacher relationship between transformational leadership and teachers' job burnout.FindingsThe results reveal that transformational leadership has a significant negative predictive effect on teachers' job burnout; this kind of leadership affects teachers' job burnout through a chain intermediary effect of social and emotional competence and student-teacher relationship.Originality/valueThis research has discovered that teacher burnout is the result of the interaction of external environmental and individual internal factors. Transformational leadership, as an external environmental factor, positively predicts the internal social-emotional competence of the teacher, and then the teacher's internal social-emotional competence positively predicts the external student-teacher relationship. Finally, the teacher-student relationship of the external environment negatively predicts the job burnout of internal individual teachers.

Diarrhea is a leading cause of death in piglets. XiaoJianZhong (XJZ) and Jingsananli-sepsis (JSS) were two traditional Chinese medicine (TCM) prescriptions to prevent and treat intestinal diseases, including diarrhea and inflammatory disease. Here, we investigated the effects of XJZ and JSS on diarrhea rate, growth performance, colonic inflammation, and caecum microbiota in piglets. A total of 18 piglets were selected and randomly divided into three groups. Control group was supplied with basal diets, while TCM1 and TCM2 groups were, respectively, supplied with XJZ and JSS in basal diets. Decreased diarrhea rate, colonic or caecal pH, and elevated apparent nutrient digestibility were observed in both TCM groups. Meanwhile, both prescriptions alleviated colonic inflammation by decreasing mRNA expression of proinflammatory cytokines and suppressing the TLR4/MyD88/NF-κB signaling pathway. Additionally, TCM1 and TCM2 prescriptions ameliorated caecum microbiota composition and increased the abundance of beneficial bacteria, together with regulations on several genes that are responsible for signaling pathways involved in cancers and metabolic diseases. Importantly, both TCM1 and TCM2 significantly promoted the average daily gain (ADG) and reduced the feed : gain (F : G) ratio. In conclusion, both TCM prescriptions effectively decreased diarrhea rate and increased growth performance by elevating apparent nutrient digestibility and gut health, via relieving colonic inflammation and ameliorating gut microbiota composition of piglets.
