The article describes activities in Russia related to the Library of Congress’ Prokudin-Gorskii collection of early 20th century color photographs. The collection was digitized in 1999/2000 and is freely available on the Internet. Russian interest in the photographs has resulted in websites, blogs, documentary films, dissertations, exhibitions, and books about the collection and the photographer and his work.  相似文献

Theorists such as Gumport (2000) suggest thatdifferent conceptions of higher education mayhave important consequences for students andsociety. We explore this possibility byconsidering a specific research question: Dostudents who attend for-profit post-secondaryschools show lower levels of civic engagementthan students who attend non-profit communitycolleges, either at the beginning of theirstudy or two years later? Using longitudinal data from the U.S. NationalCenter for Education Statistics (NCES)National Post-secondary Student Aid Survey(NPSAS90) and Beginning Post-secondary Survey(BPS), we test the hypothesis that students whoattend for-profit, post-secondary vocationalschools will show lower levels of civicengagement on several measures than similarstudents in community colleges. Studentsattending the two types of schools are alike intheir levels of civic engagement at thebeginning of their post-secondary education,but different four years later. We considerwhether observed differences in civic behaviorare due to variations in who attends thedifferent types of schools or to identifiableexperiences students may have in theirprograms, such as interactions with faculty orother students. The effect of proprietary school attendance onseven out of the ten different types of civicengagement measured here appears to be direct,rather than being mediated by measurableeducational experiences. We reflect further onprocesses that might explain the differencesand consider the policy implications of thesefindings for educational decision-makers.  相似文献

Based on the need for, suggestions about the construction, and existing measures serving as models found in the literature both inside and outside of science education, the “Children's Science Curiosity Scale” has undergone six versions using four different samples of fifth graders. Respectable internal consistency (alpha) and test-retest reliabilities have been calculated. Concurrent validity has been demonstrated by significant positive correlations with another recognized curiosity measure, and by way of significant differences between students who were interested in science and students uncertain about interest in science. Somewhat weak predictive validity has been decided by way of significant positive correlations with students' semester science grades. Construct validity has been described and established by eight judges using six criteria, and supported through the use of factor analysis where four underlying factors were hypothesized as characteristics of science curiosity. Sex differences were also explored where significant differences were not found between the genders. Suggestions have been made concerning future attempts at instrument refinement, establishing conceptual validity, future research involving other variables, and classroom use in a variety of contexts.  相似文献

After acquisition avoidance training, rats were assigned on the basis of matched run speed to the following groups: (1) maintenance of avoidance training, (2) extinction procedures with the addition of a brief shock in the goalbox, and (3) regular extinction procedures. Each group was further divided into two minor groups which experienced either change or no change in goalbox color. The results indicated : (1) that self-punitive responding was increased by goal shock, (2) that self-punitive responding was reduced by goalbox color change, and (3) that generalization of goal shock to the startbox and runway areas is a factor in self-punitive responding.  相似文献
