正Arthrospira maxima (Spirulina) is a cyanobacterium which is considered a nutraceutical because it has antioxidant, anti-inflammatory, and cytoprotective properties in different renal disease models (RodriguezSánchez et al., 2012; Aziz et al., 2018; Memije-Lazaro et al., 2018).  相似文献

This systematic review aimed to identify the level of impact of educational strategies for teaching tooth carving on the carving ability of undergraduate dental students. The PubMed-NCBI, Cochrane-CENTRAL, LILACS, Ibecs, BBO, Web of Science, and Scopus databases were searched in May 2019, for randomized controlled trials (RCTs) and two-arm non-randomized studies of interventions (NRSI) addressing educational interventions toward the dental carving of undergraduate students. Studies from the year 2000 until the search date, written in English, Portuguese, and Spanish were included. Study screening and data extraction were performed in duplicate and blinded. The data were presented narratively, considering the dental carving ability of students the primary outcome. The risk of bias was assessed using the RoB tool 2.0 and ROBINS-I, and the level of evidence was determined with GRADE. Of 3,574 studies, 6 were included, with 3 RCTs and 3 NRSIs. Very low level of evidence was provided from the NRSIs that flipped classroom (1 study; n = 140) and a student-driven revised module (1 study; n = 264) improved the carving ability of students. Additionally, there was moderate evidence of online complementary material (1 RCT; n = 30) and reinforcement class improving the carving ability of students (1 RCT; n = 29). The replacement of traditional classes by an instructional DVD (1 RCT; n = 73) and assessment of carving projects through digital systems (1 NRSI; n = 79) did not enhance the carving ability of students. Study design, risk of bias, and imprecision downgraded the level of evidence. There was a very low to moderate evidence on the effectiveness of student-driven educational approaches and complementary classes of dental anatomy in improving the dental carving ability of students.  相似文献

This paper addresses the critical role leadership plays in the implementation and facilitation of knowledge management activities. Leadership is particularly important for organizations willing to ‘evolve’ their culture to a knowledge-supporting culture. Organizational culture has been identified as the main impediment to knowledge activities, and therefore leaders should model the proper behaviors causing culture to evolve in a way that enables and motivates knowledge workers to create, codify, transfer, and use and leverage knowledge. In the literature this leadership behavior is referred to as ‘leading through a knowledge lens’. Leading through a knowledge lens has some special characteristics since it is dealing with knowledge workers having specialized expertise. Leading them can be done only by intellectual power, conviction, persuasion, and interactive dialog. It requires skills that build confidence and engagement. Therefore, leaders should establish trust and commitment that will help the knowledge organization to achieve its knowledge and business goals.  相似文献

The Pathfinder algorithm is widely used to prune social networks. The pruning maintains the geodesic distances between nodes. It has shown itself to be very useful in the analysis of, amongst others, citations in BIS (bibliometrics, informetrics, and scientometrics). It has even been proposed for the online display of the search results in an information retrieval system. However, its great time and space complexity limits its use in real-time applications and in networks of any considerable size.The present work describes an improved algorithm with considerably reduced time and space complexity. Its lower execution costs thus increase its applicability both in real time and to large networks.  相似文献

The authors have created a software system called the CAVEman, for the visual integration and exploration of heterogeneous anatomical and biomedical data. The CAVEman can be applied for both education and research tasks. The main component of the system is a three‐dimensional digital atlas of the adult male human anatomy, structured according to the nomenclature of Terminologia Anatomica. The underlying data‐indexing mechanism uses standard ontologies to map a range of biomedical data types onto the atlas. The CAVEman system is now used to visualize genetic processes in the context of the human anatomy and to facilitate visual exploration of the data. Through the use of Java? software, the atlas‐based system is portable to virtually any computer environment, including personal computers and workstations. Existing Java tools for biomedical data analysis have been incorporated into the system. The affordability of virtual‐reality installations has increased dramatically over the last several years. This creates new opportunities for educational scenarios that model important processes in a patient's body, including gene expression patterns, metabolic activity, the effects of interventions such as drug treatments, and eventually surgical simulations.

There are few pedagogical resources that describe how counselor educators can prepare counseling students to advocate for social justice. This article highlights a constructivist approach to social justice advocacy training called the Liberation Model. The principles of the Liberation Model are discussed, and recommendations for implementing the model in graduate counseling courses are provided. The purpose of the model is to help students develop the knowledge, awareness, and skills necessary for social justice advocacy.  相似文献
