HomeNetToo is a longitudinal field study designed to examine the antecedents and consequences of home Internet use in low-income families (http://www.HomeNetToo.org). The study was done between December 2000 and June 2002. Among the consequences considered was children's academic performance. Participants were 140 children, mostly African American (83%), mostly boys (58%), and most living in single-parent households (75%) in which the median annual income was 15,000 (U.S. dollars) or less. Average age was 13.8 years. Ages ranged between 10 and 18 years, Internet use was continuously recorded, and multiple measures of academic performance were obtained during the 16-month trial. Findings indicated that children who used the Internet more had higher scores on standardized tests of reading achievement and higher grade point averages 6 months, 1 year, and 16 months later than did children who used it less. Older children used the Internet more than did younger children, but age had no effect on the nature or the academic performance benefits of Internet use. Implications for the digital "use" divide are discussed. 相似文献

The big five personality dimensions and entrepreneurial status: a meta-analytical review 总被引:3,自引:0,他引:3
In this study, the authors used meta-analytical techniques to examine the relationship between personality and entrepreneurial status. Personality variables used in previous studies were categorized according to the five-factor model of personality. Results indicate significant differences between entrepreneurs and managers on 4 personality dimensions such that entrepreneurs scored higher on Conscientiousness and Openness to Experience and lower on Neuroticism and Agreeableness. No difference was found for Extraversion. Effect sizes for each personality dimension were small, although the multivariate relationship for the full set of personality variables was moderate (R = .37). Considerable heterogeneity existed for all of the personality variables except Agreeableness, suggesting that future research should explore possible moderators of the personality-entrepreneurial status relationship. 相似文献

A Web-based interface has been developed to facilitate researchers in collecting language history information online. Most
researchers use their own versions of language history questionnaires for specific studies in second language acquisition.
Although these versions of questionnaires all differ from one another in some respects, there is a significant amount of overlap
between them. Here we identify the crucial dimensions that most investigators consider important to include in such a questionnaire.
We have examined the most commonly asked questions in 41 published questionnaires, and on the basis of our analyses we propose
a general L2 language history questionnaire. Subjects can enter some or all of the information on the Web, and the results
are automatically generated as an RTF output file on the user’s desktop. 相似文献

This study aimed at examining the role of social support and self-esteem in the relationship between shyness and loneliness. The sample consisted of 399 college students, ranging in age from 18 to 30. Cheek and Buss shyness scale, multi-dimensional scale of perceived social support, Rosenberg self-esteem scale and emotional and social loneliness scale were used for data collection. Structural equation modeling showed partial mediation effects of social support and self-esteem between shyness and loneliness. Furthermore, a multi-group analysis found that shy male college students tend to have a more negative self-evaluation compared to their female counterparts. The results are discussed in terms of the conceptional context. 相似文献

In this study, dot probe tasks were employed to present performance-related or interpersonal-related words paired with neutral words, we examined the attentional bias of narcissists as well as its mechanism. Results showed that the narcissistic individuals demonstrated significant attentional bias for performance words. Specifically, they were highly vigilant to failure words and had difficulty disengaging from success words, and there was no such bias for the category of interpersonal ones. Non-narcissists, on the other hand, exhibited significant difficulty disengaging from negative words, including failure words and rejection words. From this data, it would appear that attentional bias may be a built-in cognitive attribute of narcissism. The limitations of the present study and future research directions are also discussed. 相似文献

It has been suggested by researchers that educational television programmes may support the language and literacy development for children, especially those in immigrant families. In an immigrant family, many family characteristics appear to be related to educational television programme viewing of children at home, for example, parental acculturation (the process of adapting to the new culture) and parental mediation (supervision and guidance) of television viewing. In the present work, the parental influence on children during educational television viewing was studied quantitatively, based on a sample (n = 171) of immigrant families with children aged 3–6 years collected across the U.S. The results have revealed that significant differences existed between Asian and Hispanic groups in coviewing mediation and in their children's educational television viewing. Furthermore, language in parental acculturation significantly predicted instructive and restrictive parental mediation, and parental occupation significantly predicted language in parental acculturation. This study initiates the attention to the topic of educational television viewing in immigrant families, which warrants further investigations in the future as the Asian and Hispanic immigrant population increases rapidly in the U.S. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献
