指南是依据流行病学和大规模随机临床试验的最佳证据而修订的.指南的要点是:从110/75mmHg开始,人群血压水平与心血管病发生危险呈连续相关;正常高值血压(120~139mmHg/80~89mmHg)应改善生活方式以预防高血压发生;2002年调查我国有1.6亿高血压患者,但知晓率、治疗年和控制率很低;降低高血压患者的血压水平是预防脑卒中及心脏事件的根本.  相似文献

To examine whether cultural differences exist in defining family, friend, relative, colleague and neighbour, non-student samples were drawn from Canada, China and India. The data generated several unexpected findings. (i) The means of the relationship definitions between the Chinese and Canadians were not significantly different. The means between the Chinese and Indians were significantly different. The means between the Canadians and Indians were significantly different. (ii) Females defined their relationships more interdependently than males in the Indian and Canadian samples but not in the Chinese sample. (iii) Definitions were target specific and the order of closeness differed from group to group. (iv) In the Indian and Chinese samples, participants' age was negatively correlated with closeness in defining friends, indicating that a person's perceived closeness with friends changes over the life span. Results of past research using student samples need to be interpreted with caution.  相似文献

在概述国内外有关问题发现研究的四种研究模式的基础上,从问题发现的影响因素方面对以往研究进行扩展,探讨了在不同领域里不同的材料呈现方式对儿童问题发现的影响。对262名小学三年级和五年级儿童的研究表明:儿童的问题发现有显著的领域差异,言语呈现可能比实物呈现更能促进儿童发现高质量问题,五年级儿童在问题质量的新颖性方面好于三年级儿童。  相似文献

我国婚姻法规定夫妻双方均有生育权,但事实上生育的最后支配权往往掌握在女性手中,导致近年来发生了许多有关夫妻生育权是否平等的争讼案件,受到了社会舆论和法律界的广泛关注。夫妻生育权的地位应重新审视,当因夫妻生育权的平等而发生侵权冲突时,必须在侵权法上进行适当解决,以维系各种社会关系的和谐发展。  相似文献

ABSTRACT— Integrating emotional cues from different senses is critical for adaptive behavior. Much of the evidence on cross-modal perception of emotions has come from studies of vision and audition. This research has shown that an emotion signaled by one sense modulates how the same emotion is perceived in another sense, especially when the input to the latter sense is ambiguous. We tested whether olfaction causes similar sensory modulation of emotion perception. In two experiments, the chemosignal of fearful sweat biased women toward interpreting ambiguous expressions as more fearful, but had no effect when the facial emotion was more discernible. Our findings provide direct behavioral evidence that social chemosignals can communicate emotions and demonstrate that fear-related chemosignals modulate humans' visual emotion perception in an emotion-specific way—an effect that has been hitherto unsuspected.  相似文献

政府对农村基层卫生服务投入机制的缺失和对村卫生机构的模糊定位,最终导致了农村基层卫生服务公益性主导地位的丧失.只有对村卫生机构尤其是村卫生室的性质、地位和功能加以科学的定位并以此来指导村卫生机构的兴办,才能真正实现农村基层卫生服务的公益化主导模式.  相似文献

熟练维-汉双语者第二语言的概念表征的特征   总被引:1,自引:1,他引:0  
以母语为维吾尔语,第二语言为汉语的的维吾尔族大学生为被试,使用语言内和语言间启动条件下的真假字判断任务,通过3个实验探讨了熟练的维汉双语者的第二语言的语义表征的特点,即他们的第二语言的语义表征是共同存储的还是独立存储的。结果发现,实验1语言内启动条件下,即启动刺激(维语)和目标刺激(维语)之间具有语义联想关系时,产生了显著的启动效应。实验2(启动刺激为维语,目标刺激为汉语)和实验3(启动刺激为汉语,目标刺激为维语)的跨语言启动条件下,都产生了显著的启动效应,说明被试的第二语言的语义表征是共同存储的。这些结果表明:被试的第二语言的概念表征是同第一语言的概念表征共同存储的,支持了共同存储理论。  相似文献

This study examined HIV/AIDS‐related stigma among Chinese service providers by comparing their personal attitudes toward people living with HIV/AIDS with their perception of social norms related to people living with HIV/AIDS. We randomly selected three provincial hospitals, four city/prefecture hospitals, 10 county hospitals, 18 township health clinics, and 54 village clinics from Yunnan, China. Doctors and nurses were randomly sampled proportionally to the doctor–nurse ratio of each hospital or clinic. Lab technicians were over‐sampled in order to include an adequate representation in the analysis. A total of 1,101 service providers participated in a voluntary, anonymous survey where demographic characteristics, individual attitude and perceived social norms toward people living with HIV/AIDS, discrimination intent at work, general prejudicial attitude and knowledge on HIV/AIDS were measured. A majority of the sample demonstrated a similarity between their personal views and what they thought most people in society believe. Multiple logistic regressions revealed that participants who were younger or reported personal contact with people living with HIV/AIDS were significantly more likely to report personal attitudes toward the population that were more liberal than their perceived social norms. Holding a more liberal personal attitude toward people living with HIV/AIDS than perceived social norms was significantly and negatively related to the level of discrimination intent at work, perceived discrimination at interpersonal level and the level of general prejudicial attitude toward people living with HIV/AIDS. Results underscored the importance of understanding social norms and personal attitudes in studying HIV‐related stigma and called for the incorporation of existing human capital into future HIV stigma reduction programs.  相似文献
