自然分娩与剖宫产的比较研究 总被引:1,自引:0,他引:1
剖宫产不是一种分娩方式,而是解决难产的手段。日益增高的剖宫产率成为人们关注的热点话题,自然分娩和剖宫产对母婴的健康和卫生资源的影响,有很多的研究和争议,对于没有医学指征要求剖宫产目前倾向于在知情同意的情况下尊重患者的自主权和选择权,但控制剖宫产率在一个理性的范围之内,是一个系统工程,值得全社会的关注。 相似文献

Inhibition is a widely used notion proposed to account for data obtained in choice reaction time (RT) tasks. However, this concept is weakly supported by empirical facts. In this paper, we review a series of experiments using Hoffman reflex, transcranial magnetic stimulation and electroencephalography to study inhibition in choice RT tasks. We provide empirical support for the idea that inhibition does occur during choice RT, and the implications of those findings for various classes of choice RT models are discussed. 相似文献

In two studies, one employing Spanish students and the other English students, questionnaire measures of Sensation Seeking and Openness to Experience were correlated with liking for major music types, several short music excerpts, and eight categories of painting (presented as slides). Inter‐correlations between music preference measures, painting preference, and personality are reported. In both samples, the Sensation Seeking Scale (Form V) and, particularly, the Experience Seeking sub‐scale were associated with a factor contrasting liking for ‘hard rock’ music and ‘violent–abstract’ art with liking for ‘neutral–realistic’ art and ‘easy listening’ music. Several substantial relationships between aesthetics measures and Openness to Experience (from the NEO‐PI‐R) were also found, though mostly in the English sample. The results reinforce the view that personality dimensions such as Sensation Seeking and Openness are important influences on aesthetic judgment. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

Many proposals from the analysis of social networks focused on the study of scientific collaboration have been made recently. The Small Worlds theory seems to be the most efficient to study the inner features of the scientific community. Those researches have demonstrated that small communities are based on some key individuals who connect some groups which, on the contrary, would be disconnected. One of the disadvantages from the perspective of the analysis of networks is the lack of researches of particular nodes. With the implementation of a pseudocode algorithm of Floyd, we try to avoid this. To study how a small community is formed and, as a research of one case, we observe the invisible college which is formed when connecting the fifteen most productive authors of the Journal of Personality and Social Psychology . 相似文献

Exploring the role of national culture on knowledge practices: a comparison between Spain and the UK
Cegarra-Navarro JG Sánchez Vidal ME Cegarra-Leiva D 《The Spanish journal of psychology》2011,14(2):808-819
In the context of a competitive knowledge-based economy, the knowledge provided by a firm's founders is one of the most important measures of success. This paper aims to identify the role of national culture on a founder's knowledge practices in a modern organisation. Using data collected from 258 Small to Medium sized Enterprises (SME(S)) in the Spanish and UK telecommunication industries (130 from Spain and 128 from the UK), we propose three knowledge management practices to be analysed; namely transfer, transformation and open-mindedness. This paper provides evidence that while Spanish SME(S) are more positively associated with higher levels of transfer and transformation of knowledge, UK SME(S) are more positively associated with higher levels of open-mindedness. Hence, this study serves as an important contribution to the small amount of literature currently available in this field by examining different practices that can be explained by the cultural characteristics of both countries. 相似文献

62 Caucasian, 61 Hispanic, and 44 Asian female undergraduates completed the Index of Homophobia by Hudson and Ricketts, seven items from the Attitudes Toward Lesbians and Gay Men Scale by Herek, and three questions on Affectional Orientation toward homosexuals from D'Augelli and Rose. Overall, familiarity with homosexuals as measured by self-reported number of homosexual friends correlated negatively with scores on the homophobia measures, but there were no significant differences among the groups' reported number of homosexual friends. Asian students scored significantly higher on the homophobia measures than Caucasian students. Both Asian and Hispanic students endorsed the statement significantly more often than Caucasian students that the university would be better if only heterosexuals attended. No significant differences in scores were found regarding attitudes toward lesbians versus gay men. 相似文献

The lightness hangover illusion is an unusually robust, long-lasting, prior-experience-based lightness effect. The effect occurs in the Mondrian world, a miniature chamber with interior walls covered with dark gray to black patches. The lightest patch in this scene, physically dark gray, looks white. When real whites and light grays are added to the scene, all the patches darken, but at an unusually slow rate. For several seconds, the white patches look self-luminous and the other patches continue to look very light. The luminosity fades and the other patches darken only after 2 min. We tested three possible explanations for this illusion: retinal adaptation, lightness persistence, and anchor persistence. The results clearly support anchor persistence, which is caused by the presence of steady patches, surfaces that retain their luminance values across scenes. The data also show that the size of the illusion varies directly with the number of these steady patches. 相似文献
