Weak Ties in Networked Communities     

Andrea L. Kavanaugh  Debbie Denise Reese  John M. Carroll  Mary Beth Rosson 《The Information Society》2005,21(2):119-131

Communities with high levels of social capital are likely to have a higher quality of life than communities with low social capital. This is due to the greater ability of such communities to organize and mobilize effectively for collective action because they have high levels of social trust, dense social networks, and well-established norms of mutuality (the major features of social capital). Communities with “bridging” social capital (weak ties across groups) as well as “bonding” social capital (strong ties within groups) are the most effective in organizing for collective action. People who belong to multiple groups act as bridging ties. When people with bridging ties use communication media, such as the Internet, they enhance their capability to educate community members and to organize, as needed, for collective action. This article summarizes evidence from stratified household survey data in Blacksburg, VA, showing that people with weak (bridging) ties across groups have higher levels of community involvement, civic interest, and collective efficacy than people without bridging ties among groups. Moreover, heavy Internet users with bridging ties have higher social engagement, use the Internet for social purposes, and have been attending more local meetings and events since going online than heavy Internet users with no bridging ties. These findings may suggest that the Internet—in the hands of bridging individuals-is a tool for enhancing social relations and information exchange, and for increasing face-to-face interaction, all of which help to build both bonding and bridging social capital in communities.  相似文献   

Using the Content of Online Privacy Notices to Inform Public Policy: A Longitudinal Analysis of the 1998-2001 U.S. Web Surveys     

George R. Milne  Mary J. Culnan 《The Information Society》2002,18(5):345-359

In the United States, Congress has had a long-standing interest in consumer privacy and the extent to which company practices are based on fair information practices. Previously, public policy was largely informed by anecdotal evidence about the effectiveness of industry self-regulatory programs. However, the Internet has made it possible to unobtrusively sample web sites and their privacy disclosures in a way that is not feasible in the offline world. Beginning in 1998, the Federal Trade Commission relied upon a series of three surveys of web sites to assess whether organizations post online privacy disclosures and whether these disclosures represent the U.S. definition of fair information practices. While each year's survey has provided an important snapshot of U.S. web-site practices, there has been no longitudinal analysis of the multiyear trends. This study compares a subset of equivalent individual-level web-site data for the 1998, 1999, 2000, and 2001 web surveys. Implications for using this type of research to inform public policy are discussed.  相似文献   

Environmental print and word reading     

Virginia Cronin  Denise Farrell  Mary Delaney 《Journal of Research in Reading》1999,22(3):271-282

The nature of the earliest stage of reading was examined by comparing two views about the importance of environmental print in children’s learning experiences. One theory holds that environmental print leads to the acquisition of reading through developing rudimentary representations of specific words and logos, while the second theory concerns assembled phonology and asserts that reading begins with knowing letters and their sounds. Supporters of this theory hold that knowledge of environmental print and logos is reading the environment and may not directly facilitate the acquisition of word reading. Two studies were conducted with non-reading preschool children in which environmental print knowledge was assessed and related to word recognition training. In the first session of each study children were presented with accurate representations of environmental print and logos such as ‘McDonalds’ and ‘Stop’ to find the ones they were able to identify and the ones they failed to identify. In the second session learning trials were conducted with those words from the logos that the children identified and also those that they failed to identify and with matching control words. Both studies found that the words from the known logos were more readily learned than the matching control words, but only in Study 1 were the known logo words learned more readily than the ones the children did not know. The results were discussed in terms of Gibson’s (1969) theory of perceptual learning, and supported the view that environment print and logo knowledge facilitated word reading.  相似文献   

Exercising a bounded autonomy: novice and experienced teachers’ adaptations to curriculum materials in an age of accountability     

Mary A. Burkhauser  Nonie K. Lesaux 《课程研究杂志》2017,49(3):291-312

This study explores teachers’ first enactments of a set of theory-based curriculum materials designed to support academic language instruction. Specifically, this multiple case study looks at how six middle school English teachers in three US schools adapted the materials; each case includes a pair of teachers, one novice and one more experienced. All schools were located in the same district where a school performance measurement system was being used to publicly rank schools’ academic performance and growth. Multiple measures were used to look for evidence of adaptations and why teachers made adaptations. We found that all teachers adapted the curriculum, most often in response to either perceived student needs or district reform pressures. In two cases, patterns of adaptation differed by teacher experience; experienced teachers appeared better able to adapt curriculum materials to meet instructional goals. This pattern did not hold up at the third school, where teachers faced greater reform pressures. Taken together, these findings suggest that researchers should pay more attention to the role of school and district policy on teachers’ enactments of theory-based reforms. We conclude with guidance to researchers, instructional leaders and others interested in the potential of theory-based curricula as a lever for improving classroom instruction.  相似文献   

So You Want to Be a Mentor? An Analysis of Mentor Competencies     

Dwuena C. Wyre  Cyndi H. Gaudet  Mary Nell McNeese 《Mentoring & Tutoring: Partnership in Learning》2016,24(1):73-88

As the need for mentors continues to expand in order to meet organizational and programmatic needs, so does the need for quality mentoring. Although sometimes an immediate need for quantity may foreshadow quality, this should not be the case when utilizing mentoring to achieve goals. Faculty mentor competencies are analyzed to demonstrate the importance and need for competent mentors in formal mentoring programs, specifically those in higher education. Correlation analysis is used to assess the relationship between research-based mentor competencies and Ronald E. McNair Program goals. Findings support the need for mentor competency assessment, usage of competent mentors, additional development of mentor competency models, and further study.  相似文献   

A GLIMPSE INTO THE FUTURE: PROFESSIONAL DEVELOPMENT IN THE 21ST CENTURY     

Peter James Murphy  Mary Nixon 《Higher Education in Europe》1993,18(4):99-112

Various experiments in distance continuing professional education via satellite in the Canadian province of British Columbia are described. The great distances separating the small scattered communities of the province make such a means of educational delivery’ essential; however, many professional educators have expressed doubts as to the real effectiveness of distance education programmes. The conclusion of the authors is that distance education degree programmes, backed by the latest communication technologies, are pedagogically effective and a major means to democratize access to higher education in difficult environments. These programmes definitely represent the wave of the future.  相似文献   

The role of collectivism among Latino American college students     

Irving Arevalo  Dominicus So  Mary McNaughton-Cassill 《Journal of Latinos & Education》2016,15(1):3-11

In an attempt to explain the lower Latino college graduation rate, the current study focuses on collectivism in kin and nonkin helping situations. The sample comprised 60 students at a 4-year college in the southwestern United States. Results revealed significance between ethnicity and nonkin collectivism: Latino American college students were significantly more collectivistic toward nonkin groups compared to their non–Latino American counterparts. The use of various support systems may shed some light on the necessary remedy for Latinos’ lower college graduation rate. Implications are discussed for cultural sensitivity training and program development to foster the experience and success of Latino American college students.  相似文献   

Child abuse potential inventory and parenting behavior: Relationships with high-risk correlates     

Mary E. Haskett  Susan Smith Scott  Kellie D. Fann 《Child abuse & neglect》1995,19(12)

The primary purpose of this research was to examine the construct validity of the Child Abuse Potential Inventory by comparing maltreating and high-risk parents' CAP Inventory abuse scores to their behavior during interactions with their children. A second purpose was to determine the degree to which CAP Inventory scores and parenting behavior were related to several known correlates of abuse, as measured by parent and teacher reports. Participants (n = 41) included abusive and high-risk parents and their children referred to a treatment group. Correlational analyses revealed that CAP Inventory scores and observed parenting style yielded highly related findings, supporting construct validity of the CAP Inventory. However, the CAP Inventory and observed behavior index showed a different pattern of relationships to the risk correlates. Implications for assessment of risk status are discussed and recommendations are provided for continued research.  相似文献   

Waiting to inhale: how to unhurry the moment of birth     

Malloy ME 《The Journal of perinatal education》2011,20(1):8-13

A doula and expectant mother's view of birth is forever changed when she sees a midwife simply place a newly born child below her mother at the moment of birth. The pause that the mother experiences in this moment as she studies, touches, and claims her child prompts the author to reflect in this guest editorial on ways we might be disturbing the natural sequence of birth as we deliver babies directly to their mothers' chests.  相似文献
