<正>一、精神问题精神的本质是自由。自由者有能力认知规范世界运行的普遍法则,有能力知道自己既是被规范的对象又是认知的主体。作为对象,自由者承认自由意味着对必然性的认识;作为主体,自由者不仅强调对必然性的认识已经蕴含着主体为世界立法,而且强调世界只有在精神里才能显现自己。精神知道  相似文献

<正>朱子学自12世纪创建以来,不仅极大地影响了中华民族的思想文化,而且先后风靡韩国、日本,逐渐成为东亚世界的主流思想。虽然朱子学自16世纪末17世纪初传入欧洲后有相当长一段时间未能作为一门独立学说获得长足发展①,在北美更是经历了相当长时间的沉寂期,但最终在当代(尤其是  相似文献

并发症概念的不明确,使得临床及司法实践中出现诸多问题,如部分医务人员注意力降低、医患矛盾升级,对医疗损害鉴定及判决产生了不利影响.应从疾病诊断和诊疗操作两方面理解并发症的内涵,明确并发症并不一定是医院的免责事由,并规范对这一概念的使用.  相似文献

National surveillance data indicate marked differences between Indigenous and other Australians in the prevalence of many sexually transmitted infections (STIs). Young Indigenous people bear a particularly high burden of these infections. A collaboration of university researchers, Indigenous health workers and young Indigenous people conducted 45 field interviews to examine how young Indigenous Australians keep themselves healthy and protected against STIs. Our findings emphasise the complexity of health behaviours, where individuals are rarely always ‘risky’ or always ‘safe’, as well as subtle gender differences in health practices. Preventive strategies employed by the young people were contingent on beliefs and knowledge about sexual partners, the type of relationship, the context of the sexual encounter and access to condoms. Tangible strengths such as young Indigenous people's commitments to condoms and STI screening should be celebrated and bolstered to enhance their ability to protect themselves against adverse health outcomes and enhance their resilience against STIs. Focusing on strengths helps to counter the deficit model of health commonly deployed in Indigenous health research and draws attention to health issues facing young Indigenous people and their communities, without reinforcing negative stereotypes or focusing solely on individual risk behaviour. We provide concrete recommendations for health promotion and education. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

We examine the differential signaling impact of two low pricing policies, Price Matching Guarantees and Everyday Low Prices, on consumers' trusting beliefs and purchase intentions. We demonstrate that both PMG and EDLP pricing policies signal stores' ability to offer lower prices. However, whether these sellers were perceived as benevolent, and—consequently—consumers' purchase intentions, varied critically depending upon price uncertainty. Perceived benevolence and purchase intentions were significantly higher [lower] for sellers offering PMG than EDLP when price dispersion was high [low]. Our findings offer insights into whether and under what conditions firms should adopt these low pricing policies.  相似文献

This study assumes that performing household labor is a method of maintaining the marital relationship and investigates whether higher marital commitment (personal, moral, and structural) is associated with more time spent on housework. Data taken from the second wave of the National Survey of Families and Households on 3,428 paired spouses in the United States were used to test research hypotheses. Results indicate that (a) husbands with higher moral commitment, or those married to a wife with lower moral commitment, do more routine housework, and (b) husbands with stronger personal commitment do less routine housework and their wives do more. The interplay of gender ideology and marital commitment as they pertain to housework performance for each gender is discussed.  相似文献

The social brain undergoes developmental change during adolescence, and pubertal hormones are hypothesized to contribute to this development. We used fMRI to explore how pubertal indicators (salivary concentrations of testosterone, oestradiol and DHEA; pubertal stage; menarcheal status) relate to brain activity during a social emotion task. Forty‐two females aged 11.1 to 13.7 years underwent fMRI scanning while reading scenarios pertaining either to social emotions, which require the representation of another person’s mental states, or to basic emotions, which do not. Pubertal stage and menarcheal status were used to assign girls to early or late puberty groups. Across the entire sample, the contrast between social versus basic emotion resulted in activity within the social brain network, including dorsomedial prefrontal cortex (DMPFC), the posterior superior temporal sulcus, and the anterior temporal cortex (ATC) in both hemispheres. Increased hormone levels (independent of age) were associated with higher left ATC activity during social emotion processing. More advanced age (independent of hormone levels) was associated with lower DMPFC activity during social emotion processing. Our results suggest functionally dissociable effects of pubertal hormones and age on the adolescent social brain.  相似文献
