Online Teaching Resources     

Annis Lee Adams 《Public Services Quarterly》2020,16(3):172-178

Abstract

Because of the global COVID-19 pandemic during the spring of 2020, colleges and universities found themselves rapidly moving all courses to online modalities, a format that many instructors were not experienced in or comfortable with. Academic librarians were called upon to help support faculty in this sudden transition, as well as migrating their own library services and instruction online. For many, it felt like a mad scramble to find best practices for online teaching, or even just “good-enough” practices, as well as specific tools that instructional faculty and librarians could utilize to keep their students engaged and learning during such a trying time. At the time of this writing, some universities have announced that they will continue to hold most, if not all, courses online in the fall 2020 term. Resources to support online teaching are critical now, and they will continue to be important going forward even after the global pandemic subsides. The reviews in this column cover a variety of online instructional tools and instructional support sites. The resources reviewed range from providing best practices for online pedagogy, creating engaging formative assessment tools, developing video discussion boards, creating interactive images, using virtual bulletin boards for student collaboration, and ensuring online content meets accessibility requirements. These resources will be useful for librarians and instructional faculty as they continue to teach in the online environment.  相似文献   

Potent antiulcerogenic activity of ethanol extract of leaf ofPiper betle Linn by antioxidative mechanism     

Biswajit Majumdar  Susri Ray Chaudhuri  Arun Ray  Sandip K Bandyopadhyay 《Indian journal of clinical biochemistry : IJCB》2002,17(1):49-57

Pretreatment of an ethanolic extract of leaf ofPiper betle linn at a dose of 200mg/kg body weight, orally administered to rats for ten consecutive days, was found to possess a significant protective action against gastric lesions induced by indomethacin. The extract pretreatment resulted in significant increase in superoxide dismutase (SOD) and catalase (CAT) activity, increase in mucus, hexosamine and total thiol group content, but marked reduction in oxidatively damaged protein and peroxidised lipid levels as compared to untreated ulcerated control. The extract was also found to possess both superoxide and hydroxyl free radical scavenging action. The present observations establish the efficacy of the extract in prevention of experimentally induced peptic ulcer by indomethacin and antioxidant property appears to be predominantly responsible for such cytoprotective activity in the experimental model.  相似文献   

Serum oestradiol in women with carcinomas of the breast and uterine cervix

Endogenous oestrogens are thought to be involved in breast cancer, but few studies could show the direct relationship between hormones and pathological process of the disease. In the present study, oestradiol was estimated in the serum of pre-and postmenopausal breast cancer patients along with normal healthy controls and patients with carcinoma of the uterine cervix which is not dependent on oestrogens. Premenopausal patients with breast cancer showed higher levels of oestradiol as compared to premenopausal control women as well as cervical cancer patients. Whereas, no statistically significant differences were observed in serum oestradiol levels amongst postmenopausal groups of breast cancer, cervical cancer and normal women. The result of the study reflects the association of oestradiol as well as its difference in the pathological events of pre and postmenopausal breast cancer.  相似文献   

Scientific teams and institutional collaborations: Evidence from U.S. universities, 1981-1999     

James D. Adams  Grant C. Black  Paula E. Stephan 《Research Policy》2005,34(3):259-285

This paper explores recent trends in the size of scientific teams and in institutional collaborations. The data derive from 2.4 million scientific papers written in 110 top U.S. research universities over the period 1981-1999. The top 110 account for a large share of published basic research conducted in the U.S. during this time.We measure team size by the number of authors on a scientific paper. Using this measure we find that team size increases by 50% over the 19-year period. We supplement team size with measures of domestic and foreign institutional collaborations, which capture the geographic dispersion of team workers. The time series evidence suggests that the trend towards more geographically dispersed scientific teams accelerates beginning with papers published at the start of the 1990s. This acceleration suggests a sharp decline in the cost of collaboration. Our hypothesis is that the decline is due to the deployment of the National Science Foundation's NSFNET and its connection to networks in Europe and Japan after 1987.Using a panel of top university departments we also find that private universities and departments whose scientists have earned prestigious awards participate in larger teams, as do departments that have larger amounts of federal funding. Placement of former graduate students is a key determinant of institutional collaborations, especially collaborations with firms and with foreign scientific institutions. Finally, the evidence suggests that scientific output and influence increase with team size and that influence rises along with institutional collaborations. Since increasing team size implies an increase in the division of labor, these results suggest that scientific productivity increases with the scientific division of labor.  相似文献

Doing the right thing: infants' selection of actions to imitate from observed event sequences     

Brugger A  Lariviere LA  Mumme DL  Bushnell EW 《Child development》2007,78(3):806-824

Two studies were conducted to investigate how 14- to 16-month-old infants select actions to imitate from the stream of events. In each study, an experimenter demonstrated two actions leading to an interesting effect. Aspects of the first action were manipulated and whether infants performed this action when given the objects was observed. In both studies, infants were more likely to imitate the first action when it was physically necessary to generate the effect, and in Study 2 they were also more likely to imitate the action when it was socially cued. It seems that infants' own knowledge of space and causality as well as their sensitivity to others' social signals both contribute to their tendency to imitate actions.  相似文献
