Those who study social networks encounter an all-too-often conundrum in academia: the richness of data sets coupled with methodological complications. This article highlights three of the most salient issues facing social network scholars and potential ways of overcoming them. By discussing the quantitative measurement of the network in question, the specific variables under examination, and the overall goal(s) of the research project, readers will understand both the costs and rewards associated with an area of communication, psychology, and sociology scholarship that has existed and thrived for more than a half century. 相似文献

ABSTRACT How do educators capitalize on students’ comfort with ubiquitous communications in order to develop information literacy skills required in the 21st century? A curriculum materials librarian and a professor in the School of Education present an approach that uses library instruction, online research scaffolds, and peer evaluation within a class wiki to enhance student research practices and academic achievement. The explosion of information sources and access to networked technologies has provided the opportunity to “ratchet up” the expectations for student research in higher education. The Association of College & Research Libraries's information literacy standards for higher education provide a framework for setting these expectations. The authors describe features of an introductory education course that seeks to enhance honors freshman students’ knowledge of library research resources, efficient research skills, and scholarly writing, as described in these standards. 相似文献

The research reported here focuses on grade 7 (12‐year‐old) students’ epistomological views prior to and after exposure to a teaching unit especially developed to introduce the constructivist view of science. A clinical interview was used to assess students’ understanding about the nature of scientific knowledge and inquiry. Students’ initial epistemological stance is that scientific knowledge is a passively acquired, faithful copy of the world, and that scientific inquiry is limited solely to observing rather than constructing explanations about nature. We found that it is possible to move students beyond this initial view. 相似文献

Plant Growth Promoting Rhizobacteria 总被引:1,自引:0,他引:1

Plant Growth Promoting Rhizobacteria (PGPR) are a group of bacteria that enhances plant growth and yield via various plant growth promoting substances as well as biofertilizers. Given the negative environmental impact of artificial fertilizers and their increasing costs, the use of beneficial soil microorganisms such as PGPR for sustainable and safe agriculture has increased globally during the last couple of decades. PGPR as biofertilizers are well recognized as efficient soil microbes for sustainable agriculture and hold great promise in the improvement of agriculture yields. 相似文献

Knowledge management has an important role to play in both organizational and national cultures. In order to have a paradigm shift from a knowledge hoarding to a more knowledge-sharing culture, knowledge management should be used as part of the human capital strategy for the organization. The impact of culture on knowledge management has been studied widely, but little has been written on how knowledge management can affect organizational culture. This paper provides a thought-piece on addressing this overlooked area. 相似文献

The study purposes were to examine: (a) the determinants of exercise intention and past exercise behavior (PEB) using the theories of reasoned action and planned behavior, and (b) the moderating influences of sex and exercise group (meeting or not meeting exercise guidelines). Participants (n = 676 adolescents) completed self-reported measures of their exercise attitude, subjective norm, perceived behavioral control (PBC), intention, and PEB. We found that attitude, subjective norm, and PBC explained 55% of the variance in intention, and intention and PBC explained 51% of the variance in PEB. While we found sex and exercise group differences across the study measures, we did not find evidence of significant moderation. Thus, the theory constructs predicted intention and PEB similarly across sex and exercise groups. 相似文献

Research has shown that holding conflicted attitudes (ambivalence) about political decisions may lead people to act as ideal citizens. One example of this normatively ideal behavior is seen in research linking ambivalence to information seeking. To expand on this line of inquiry, this study examines the over-time relationship between ambivalence and information seeking. We use three-wave panel data collected during the 2012 election to determine whether over-time relationships exist between these variables and test the causal direction of these relationships. We find that use of counterattitudinal information increases ambivalence, which leads people to seek out more counterattitudinal information. We also find that use of pro-attitudinal media decreases levels of ambivalence. 相似文献
