食管癌研究的历史回顾和哲学思考 总被引:7,自引:3,他引:4
食管癌研究可分为病因学、发病机制和防治三个部分,涵盖了流行病学、生物化学、病理学、肿瘤学、分子生物学等多个学科。尽管两千多年前,我国学者以开始记载和描述食管癌,但直到近代特别是现代科学技术的进步才对食管癌有了系统的认识。回顾食管癌的研究史,不难看出,正确的研究方法和科学思路在揭示食管癌发病机制和控制食管癌发病率和死亡率中起关键的作用。辨证地剖析机体内部和外界环境之间的关系,人群研究和实验室研究,个体化局部治疗和全身综合治疗,基础和临床研究,传统方法和现代高科技的有机结合,国内外合作研究与小范围研究,研究者与食管癌患者之间的关系等方面的关系,是指导食管癌 研究的重要环节。 相似文献

The sibling relationship has recently become the focus of much research in developmental psychology. The family system perspective implies the presence of a sibling with mental retardation will impact on the psychological development and functioning of their typically developing siblings. Past reviews of the literature have found this impact to be negative but there is the suggestion of positive consequences to having a sibling with mental retardation. The present meta-analysis sought to quantitatively integrate 25 studies and 79 effect sizes from the literature on the siblings of individuals with mental retardation. A small negative effect for having a sibling with mental retardation was discovered that could not be attributed to a publication bias or some other artifact. This negative effect was greatest for direct observation measures, measures of psychological functioning, especially depression, and for children. Limitations to this meta-analysis and directions for future research are discussed. 相似文献

A critical developmental task of midlife involves reviewing one's past as well as preparing for one's future. The ability to identify past choices, task responsibility for them, and utilize developing patterns in future decision making is seen as a critical component of continued adult development. The Choicemap offers a structured clinical tool to guide such a midlife review. Engaging in this process assists adults in developing choicemaking skills, and provides a powerful clinical intervention. 相似文献

Adolescents in rural areas use substances at rates comparable to urban adolescents; understanding causes of rural adolescent substance use is critical if prevention efforts are to succeed. The present review has three primary goals: (1) to define rural, (2) to evaluate the empirical evidence regarding correlates and causes of rural adolescent substance use from a social contextual framework (L. V. Scaramella, R. D. Conger, R. Spoth, & R. L. Simons, in press), and (3) to discuss the malleability of theoretically based risk or protective factors in rural settings. The review concludes with a discussion of the difficulties and challenges of implementing prevention programs in rural areas. 相似文献

We investigated the perceived distance of targets in convex and plane mirrors. In Experiment 1, 20 subjects matched the distance of targets in a real scene to the distance of a virtual target in different mirrors. The matched distances were much larger for convex mirrors than for a plane mirror. In Experiment 2, 20 subjects viewed two targets in a mirror and adjusted their own positions so that the distance to the closer target was perceived to equal the distance between the targets. The mean distance to the closer target was smaller for the convex mirrors than for the plane mirror. In Experiment 3, 20 subjects adjusted the position of a target so that the distance to it in a mirror was perceived to equal the distance designated by the experimenter. The best-fitting power functions showed that the scaling factors were larger for the convex mirrors than for the plane mirror, but the exponents were smaller for the convex mirrors than for the plane mirror. It is suggested that distance in the convex mirrors was perceived to be larger than in the plane mirror, and that the growth of perceived distance in the convex mirrors was slower than in the plane mirror. 相似文献

Discussions on the congruence, compatibility, and contradictions between science and religion have been going on since the rise of modern science. In our own times, there are many efforts to build bridges of harmony between the two. Most of these are anchored to particular religious traditions or denominations and also (often) to specific disciplines, notably cosmology, physics, and biology. Though these discussions serve commendable purposes for members of specific faiths and/or disciplines, they are also, for precisely this reason, of restricted appeal. There are not too many discussions of the topic that consider science and religion from a global perspective. It will therefore be useful to define science and religion in terms of their unique characteristics, draw the line of demarcation between them, and show where they overlap. This is what this paper attempts to do. 相似文献

Forgiveness: Who Does It and How Do They Do It? 总被引:5,自引:0,他引:5
Michael E. McCullough 《Current directions in psychological science》2001,10(6):194-197
Forgiveness is a suite of prosocial motivational changes that occurs after a person has incurred a transgression. People who are inclined to forgive their transgressors tend to be more agreeable, more emotionally stable, and, some research suggests, more spiritually or religiously inclined than people who do not tend to forgive their transgressors. Several psychological processes appear to foster or inhibit forgiveness. These processes include empathy for the transgressor, generous attributions and appraisals regarding the transgression and transgressor, and rumination about the transgression. Interpreting these findings in light of modern trait theory would help to create a more unified understanding of how personality might influence forgiveness. 相似文献

This article provides a construct-by-construct review of the effectiveness of sexual asault prevention programs in modifying sexual assault-related attitudes, cognitions, emotions, and behaviors. This article also discusses variables that may moderate program effectiveness, variables that may mediate program effectiveness, methodological issues, programs for special populations, and iatrogenic effects. In general, sexual assault prevention programs have been shown to be effective in producing short-term reductions in rape-supportive attitudes. There is insufficient evidence, however, to conclude that such programs are effective in reducing the incidence of sexual assault. 相似文献
