Summary After reviewing some applications and reports of evaluation of computer-based education (CBE) in higher education, this paper provides a discission of environmental, instructional, and managerial issues in development, implementation and maintenance of computer-based education processes and materials. A short list of guidelines for development is also provided. 相似文献

This paper argues that media and communications theory, as with cultural and creative industries analysis, can benefit from a deeper understanding of economic growth theory. Economic growth theory is elucidated in the context of both cultural and media studies and with respect to modern Chinese economic development. Economic growth is a complex evolutionary process that is tightly integrated with socio‐cultural and political processes. This paper seeks to explore this mechanism and to advance cultural theory from an erstwhile political‐economy perspective to one centred about the co‐evolutionary dynamics of economic and socio‐political systems. A generic model is presented in which economic and social systems co‐evolve through the origination, adoption and retention of new ideas, and in which the creative industries are a key part of this process. The paper concludes that digital media capabilities are a primary source of economic development. 相似文献

Abstract Objective: To assess students’ human papillomavirus (HPV) knowledge, attitudes, and behaviors. Participants/ Methods: Students (N = 1,282) at a large, public university in the Northeast United States completed a questionnaire during February 2008 assessing HPV knowledge, prevalence, transmission, cervical cancer risk and stigma; sexual behavior, vaccination status, as well as past and preferred sources of information about HPV and sexual health. Results: A majority of respondents know of HPV. However, understanding was insufficient in several important areas. Overwhelmingly, respondents heard about HPV via television commercials yet preferred to obtain sexual health information from physicians. Hearing about HPV on a TV commercial was associated with increased knowledge. More knowledge of HPV was associated with less stigma. Men exhibit a higher level of stigma and less knowledge than women. Conclusions: Publicly funded health campaigns aimed at increasing knowledge about HPV are overdue and necessary. This is especially true for efforts targeting young adults about this extremely common sexually transmitted infection (STI). 相似文献

A list of consequential developments in the field of statistics for the past quarter-century must include the creation and implementation of the Advanced Placement (AP) program in Statistics. This program has introduced millions of high school students to our discipline over the past 18 years, contributing to the large increase in the number of undergraduate students pursuing statistics as their major in college. ASA members and leaders have played a substantial role in shaping this program and furthering its success. 相似文献

We propose a generic randomization device (RD) for the estimation of mean of quantitative sensitive characteristic that make use of additive and multiplicative scrambled responses with blank card strategy. For this generic RD, we work with 12 choices and derive statistical properties of each model and give many immediate results in corollaries. It is interesting to note that various existing models can now be viewed as the special cases of this RD. Finally, various empirical studies have been done for each of these models to evaluate the efficiency performance. 相似文献

Extremely discordant (ED) and concordant (EC) sib pairs are recommended by Risch and Zhang ( 1995, 1996 ) and Zhang and Risch ( 1996 ) for the detection of linkage on the basis of power analysis. They did not, however, include both discordant and concordant sib pairs simultaneously in the test statistic. We construct a new test statistic including both types of sib pairs. The size of the sample needed to identify the sib pairs and parents, who will be genotyped, is reduced substantially by including a hybrid of discordant and concordant sib pairs in the analysis. This mixed design also provides a common parameter that simplifies meta-analysis of sib pair linkage studies. 相似文献

中国人民银行2019年发布的国民金融素养调查结果显示,我国国民金融素养整体有待提高.与此同时,随着互联网时代的到来,互联网已成为居民获取各类信息的重要途径.然而,相关文献却鲜有关注互联网使用对居民金融素养的影响.为此,利用CFPS2014调查数据,基于中介效应模型实证检验了互联网使用对居民金融素养的影响及其机制.结果表明:(1)互联网使用显著提高了居民金融素养,且对高级金融素养的提升作用更大,部分结论在CFPS2018调查样本中依然成立;(2)互联网使用对初中、高中及大专学历群体的金融素养产生了显著的正向影响,且对所有收入群体的金融素养也产生了显著的正向影响,但这种影响在不同学历群体之间存在显著差异,在不同收入群体之间则不存在显著差异;(3)互联网使用可以通过线上和线下社会互动两条途径影响居民的金融素养.上述结论表明,应通过大力提高居民互联网的使用率、积极开展金融知识专项教育培训、着力拓展线上和线下社会互动渠道等方式,推动居民金融素养的有效提升. 相似文献

读写萌发是幼儿早期阅读和书写自然发展的历程,幼儿的读写萌发始于家庭,家庭语言环境的营造直接影响日后幼儿对语言的认知和发展。文章在家庭的自然环境中,通过参与式观察和作品分析法对幼儿读写萌发现象进行个案研究,研究得出以下结论:幼儿阅读萌发形式多样,为幼儿阅读能力发展奠定基础;使用中文的幼儿在书写形式和原则上与使用英文的幼儿相比有所差异;幼儿阅读和书写萌发是平行发展且相互关联的。这些研究将为鼓励和促进幼儿读写能力发展提供重要指导。 相似文献

This research investigates the relationship between how a household receives financial information and the degree to which investment portfolios are diversified. Diversification is measured as allocation across asset classes and share of assets held in each asset class. Propensity score-based techniques incorporating stratification and weighting are employed to better isolate causal links, while also controlling for objective and subjective financial literacy and overconfidence. Results indicate that the use of financial planners and brokers is associated with an increase in asset class diversification. Households that consult with financial planners and bankers allocate their wealth systematically different from those who do not. These results highlight the role that financial professionals play in helping households make investment decisions. 相似文献
