We examined how relationships among intrapersonal (i.e., attitudes and beliefs about smoking) and ecodevelopmental (i.e., family, school, and peer) factors influence risk for lifetime smoking in immigrant Hispanic adolescents. Our sample was comprised of 223 immigrant Hispanic adolescents and their families and was drawn from 3 middle schools in a single school district. Data collected is a result of adolescent and parent completed questionnaires as well as county school data (i.e., GPA, teacher reported effort and conduct, absences). Results indicated only poor school functioning, peer smoking, and lack of perceived harm concerning smoking were directly related to adolescent lifetime smoking. Poor school functioning and peer smoking mediated the relationship between family functioning and adolescent smoking. Implications of these results for the design of smoking preventive interventions for immigrant Hispanic adolescents are discussed.  相似文献

After Neo-Confucianism, the study of contemporary Confucianism became more diverse. Its original uniformity was replaced by diversity. During this time, however, Post-Confucianism became increasingly prominent. Post-Confucianism comes from a post-modernist context and was influenced by a post-modernist ideological mode, and so its appearance was inevitable. It was also closely linked to significant philosophical issues after the change in times, and therefore questioned and challenged Neo-Confucianism which was based on a pattern of modernity. Post-Confucianism represents a new trend in the contemporary development of Confucianism. From a cultural point of view, this essay systematically investigates three internationally renowned schools of Post-Confucianism and their backgrounds, noting their similarities and differences, examining their significance, and determining their meaning. By doing so, it intends to outline an intelligible framework for this academic trend and highlight the significance of Post-Confucianism for the development of contemporary Confucianism.  相似文献

Jaeger is supportive of our experiment and the claims we make, arguing that the weight of current evidence shows the brain making a distinction between regular and irregular inflectional morphology. Seidenberg & Arnoldussen are unsupportive, criticizing our work on theoretical and methodological grounds. Seidenberg & Arnoldussen’s major worries—that we have misunderstood connectionist theory’s predictions and have committed a “Difficulty Matching Error” in testing them—are important to consider but turn out to be groundless. At bottom, Seidenberg & Arnoldussen fail to recognize the consequences of our choice of German words, rather than English, as stimuli. Once the concept of “difficulty” is given substance in this context, it appears that in German, the brain activates more extensively when dealing with what in the connectionist universe should be, if anything, the easier stimuli, not the harder ones as suggested by Seidenberg & Arnoldussen. Thus regularity cannot be reduced to difficulty.  相似文献

采用ASL—4200R型眼动仪,对28名小学五年级学生阅读图文课文的眼动过程进行考察,结果表明:(1)不同呈现方式课文的阅读成绩具有非常显著差异,图文课文化于文字课文;(2)不同呈现方式课文的注视次数、注视频率、眼跳距离和回视次数存在显著差异,图文课文显著少于或低于文字课文,而注视点持续时间则相反;(3)不同难度课文的眼动指标,文字课文只有注视次数一项眼动指标具有显著差异,而图文课文有注视频率和回视次数二项眼动指标具有显著差异。  相似文献

Behavior based safety approaches have proven effective in reducing accidents in industrial settings, but cannot easily be extended to commercial driving. For considerable periods of working time, truck drivers are alone, and do not interact with peers. It might be possible to use data gathered by new in-vehicle technology to provide real-time and post-shift feedback to drivers about their driving behavior. This paper reports the results of focus group interviews conducted with subject matter experts from the trucking industry (truck drivers, supervisors, managers, and other involved persons, such as insurance industry safety professionals). The focus groups discussed safety critical behaviors in commercial driving, the best way to provide feedback to truck drivers, and benefits of feedback by technology as well as concerns drivers and operators may have regarding monitoring and feedback systems. The focus group discussions showed that, in general, drivers would like to receive more feedback and that feedback by technology is acceptable, if designed and implemented properly. In addition, the participants had many suggestions on how to properly design and implement such systems.  相似文献

本研究采用文献研究法,查阅了2000年以来中学语文和历史教案共303篇,对教案中教学目标的相关信息作点计数据处理,并进行卡方检验,结果表明:⒈近几年来我国中学语文和历史教学绝大多数采用布卢姆的教育目标分类取向;⒉两者的教学目标侧重于认知领域;⒊两者在认知和情感领域的目标要求学生达到的水平偏低,在动作技能领域的目标要求学生达到的水平偏高;⒋中学历史教学目标中对动作技能领域的理解有偏差;⒌两者在认知和情感领域的教学目标陈述时用词单一或含糊,而动作技能领域教学目标的陈述较清晰。研究结果提示,提高广大一线教师有关教学目标的分类理论及科学地运用教学目标的陈述技术仍有很长的路要走。  相似文献
