This study investigated the relationships between university EFL teachers' perceived teaching support, teacher innovation, and teaching satisfaction in online teaching environments, especially the mediating role of teaching efficacy. The results of an online questionnaire survey with 473 university EFL teachers revealed that although online peer support did not directly make any difference to teacher innovation and teaching satisfaction, greater perceived support in the form of teaching resources and teaching autonomy improved university EFL teachers' online teaching satisfaction. Online teaching efficacy significantly mediated the relationships between teaching support and teacher innovation and satisfaction. The results offer significant implications for improving the effectiveness of EFL teaching and promoting university EFL teachers' innovation and satisfaction in online teaching environments.
In this paper, we introduce a military boxing learning system implemented by 3D motion capture, Web3D and 3D interactive technologies, which can support that users observe and learn the details of each action of the military boxing under different views and scales by translating, rotating and zooming the 3D human body models. Beside keyboards and mice, smartphones also can be used in the system, which can provide some natural interactive operations by voice and touch technologies. The system can be extended to tai chi boxing, radio gymnastic exercises and other routines actions.
Hepatic ischemia–reperfusion (IR) injury remains a common issue lacking effective strategy and validated pharmacological targets. Here, using an unbiased metabolomics screen, this study finds that following murine hepatic IR, liver 3‐hydroxyanthranilic acid (3‐HAA) and quinolinic acid (QA) decline while kynurenine and kynurenic acid (KYNA) increase. Kynurenine aminotransferases 2, functioning at the key branching point of the kynurenine pathway (KP), is markedly upregulated in hepatocytes during ischemia, shifting the kynurenine metabolic route from 3‐HAA and QA to KYNA synthesis. Defects in QA synthesis impair de novo nicotinamide adenine dinucleotide (NAD) biosynthesis, rendering the hepatocytes relying on the salvage pathway for maintenance of NAD and cellular antioxidant defense. Blocking the salvage pathway following IR by the nicotinamide phosphoribosyltransferase inhibitor FK866 exacerbates liver oxidative damage and enhanced IR susceptibility, which can be rescued by the lipid peroxidation inhibitor Liproxstatin‐1. Notably, nicotinamide mononucleotide administration once following IR effectively boosts NAD and attenuated IR‐induced oxidative stress, inflammation, and cell death in the murine model. Collectively, the findings reveal that metabolic rewiring of the KP partitions it away from NAD synthesis in hepatic IR pathophysiology, and provide proof of concept that NAD augmentation is a promising therapeutic measure for IR‐induced liver injury.
It is well-acknowledged that organizational sustainability largely depends on employees’ innovative behavior, which is the same case with higher education institutions. This study aimed to explore the characteristics of and relationships between faculty members’ mastery goals and innovative behavior under the framework of achievement goal theory in the research context. Results from an anonymous questionnaire survey of 621 Chinese faculty members revealed a four-dimensional structure of mastery goals (task-approach goals, task-avoidance goals, learning-approach goals, and learning-avoidance goals) and a five-dimensional structure of innovative research behavior (opportunity exploration, generativity, formative investigation, championing, and application). The faculty members reported a high level of mastery goals for research and a moderate level of innovative research behavior respectively. Male faculty scored higher on opportunity exploration, formative investigation, championing, and application than their female counterparts. Innovative research behavior showed significantly positive associations with task-approach goals, negative associations with learning-approach goals, and no significant association with mastery-avoidance goals except the positive link of learning-avoidance goals to championing. These results have implications for understanding faculty research motivations and behaviors and effectively stimulating their innovativeness in research for sustainable development of higher education institutions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
