This study employed aggregate data drawn from the World Bank database for 61 countries for the period 2000 to 2009 and quantitatively evaluated the impact of Information and Communication Technology (ICT) diffusion on health outcomes. The empirical methodology included a dynamic panel data (DPD) model and a fixed effect (FE) model. The results show that the diffusion of the Internet and fixed and mobile telephones was positively associated with life expectancy. The diffusion of fixed and mobile telephones was associated with a reduction in infant and under-five mortality rates. The diffusion of the Internet was associated with a higher prevalence of human immunodeficiency virus (HIV). The diffusion of mobile phones was associated with decreases in the incidence of tuberculosis. An important policy implication for governments worldwide is that investing in ICT infrastructures and educating the public the use of ICT can be an alternative policy to improve health.  相似文献

阅读发展相关的认知技能:汉语和英语的比较   总被引:9,自引:0,他引:9  
对英语和汉语阅读获得所需要的认知技能及发展性阅读障碍儿童认知缺陷的研究进行了回顾。分析表明阅读发展所需认知资源表现出了跨语言的一致性,都要求有充足的学习与记忆能力和正常的视觉正字法技能,语音和语义知识表征足够精细;阅读障碍儿童的主要认知缺陷也表现出了跨文字的一致性,都包括语音缺陷和一般的学习与记忆问题。然而儿童所面临的语言文字特性会影响到阅读技能获得的难易和发展性阅读障碍的表现  相似文献

心理行为干预对乳腺癌患者情绪反应及免疫功能的影响   总被引:29,自引:0,他引:29  
按随机和匹配原则,将40名乳腺癌放疗患者分入干预组和对照组。对干预组患者进行为期4周的心理行为干预,对照组仅接受相应的医药治疗。以肿瘤病人情绪适应问卷(MAC)和免疫测试法研究患者干预前后的情绪反应和免疫功能,探讨心理行为干预对乳腺癌患者情绪反应和免疫功能的影响。结果发现,心理行为干预有利于提高患者NK细胞活性(NKCA);并有助于维持放疗期间患者的白细胞水平。  相似文献

This paper introduces a method for finding the non‐dominated set in criterion space of an MOLP problem based on Fourier–Motzkin Elimination. The method incorporates a procedure that eliminates decision variables from constraints and transforms a feasible region from decision space to criterion space. While avoiding characterization of the efficient set in decision space, it finds the non‐dominated set in criterion space. After the decision maker's most preferred criterion vector has been identified, the corresponding efficient solutions can be found by backward substitution. The method was implemented in MATLAB using a tabular form and computational experiments were conducted. The results indicate that although the method performs well for relatively small problems, it can be computationally intensive for larger problems. Nonetheless, the method is intuitively appealing and it provides useful insights into the geometry and theory of MOLP. As such it makes it a valuable educational tool for students of multi‐criteria decision analysis. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

杂谈出家人     
去年阳春三月我去杭州,见香客蜂拥,更多于往年。交通堵塞,车行缓慢,不禁感慨系之。假如佛祖菩萨果然大慈大悲,而且法力无边,那么,就把幸福普遍赐予人们,又何必让大家辛苦奔波,非要到寺院进香不可呢!然而这大约只是我这样不信佛者的意见。在香客们看来,他们大约只有朝寺进香,亲自向佛祖菩萨礼拜之后,佛祖菩萨才能应允实现他们的愿望。信仰不同,想法各异,行动自然也就两样。我只是不知道他们中间多少是虔诚的信仰者,多少是临时抱佛脚的功利主义者。说到虔诚信仰,使我进一步想到了出家人。在中国,出家人是信仰宗教的代名词。其实,出家人固然是…  相似文献

The context of intergroup relations in Aotearoa/New Zealand was investigated using perceptions of history by Maori (Polynesian‐descended) and Pakeha (European‐descended) samples from university and the general public. There was strong consensus that the Treaty of Waitangi was the most important event in New Zealand's history, but only Maori, the subordinate ethnic group, showed in‐group favouritism in their judgments regarding the Treaty. Pakeha, the dominant group, showed outgroup favouritism, and distanced themselves from past injustices using linguistic strategies. Maori students showed interest in their ethnic origins (ontogeny), rating the distant past and Polynesian history higher, and free‐recalling more events prior to European arrival than other groups; Maori in the general population shared a more similar perception of history to Pakeha. Both in‐group favouritism and ontogeny were found in sentence‐completion choices. Historical perceptions were strongly related to positions on current political issues. Results are related to social identity theory, social representations theory, and social dominance theory. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

Two new methods to estimate the asymptotic covariance matrix for marginal maximum likelihood estimation of cognitive diagnosis models (CDMs), the inverse of the observed information matrix and the sandwich-type estimator, are introduced. Unlike several previous covariance matrix estimators, the new methods take into account both the item and structural parameters. The relationships between the observed information matrix, the empirical cross-product information matrix, the sandwich-type covariance matrix and the two approaches proposed by de la Torre (2009, J. Educ. Behav. Stat., 34, 115) are discussed. Simulation results show that, for a correctly specified CDM and Q-matrix or with a slightly misspecified probability model, the observed information matrix and the sandwich-type covariance matrix exhibit good performance with respect to providing consistent standard errors of item parameter estimates. However, with substantial model misspecification only the sandwich-type covariance matrix exhibits robust performance.  相似文献

Previous research on the relationship between collectivism and corruption has not investigated their co‐variation over time. In this study, we use Google Ngram Viewer to track the frequency of words related to collectivism and corruption in American books (1800–2000) and in Chinese Books (1970–2008). The results demonstrate that a positive association between the usage of these terms during the periods in both Chinese and American books, with changes in words related to collectivism preceding changes in words related to corruption in American books. The theoretical and practical implications are also discussed.  相似文献
