医学科研与医学科研伦理的辩证思考

医学科研中出现许多伦理问题。其必然性在于科学与伦理的不同：即属性不同、评价标准不同、变革速度不同。医学伦理可以告诉人们什么样的医学科研活动是善的,什么样的科研行为是应该做的。医学科研中要把握医学伦理观,体现医学科技观,富有医学创新观。     

How do shy people expand their social networks? Using social surrogates as a strategy to expand one's network

The authors examined the use of social surrogates by shy people to expand their social network when entering a new environment, following Bradshaw's social surrogate hypothesis. The authors conducted a panel survey of 70 friendship pairs of students 7 months after they entered university. The results revealed that when a friend acted as a surrogate, the shy students extended their joint networks more. In contrast, not-shy students extended their networks regardless of whether a friend acted as a surrogate. These results indicate that even shy people can adjust indirectly to new social circumstances because they can expand their social networks by using a close friend as a surrogate.     

我国当代青少年情感素质现状调查

本研究在青少年情感素质理论和发展的情感分类思想指导下, 在理论构想与实践探索相结合的基础上, 编制了富有原创性的内含6个分问卷、可测查青少年2层次6大类29种情感发展状况的调查工具——《青少年情感素质问卷》, 并以此对我国3类地区9大城市及其郊县的117所学校的25485名青少年学生进行首次大规模情感素质测查。结果发现: 我国青少年情感素质整体上处于积极正向状态, 但亟待提高; 男女生情感素质主要存在结构性差异; 情感素质未随学段升高而提高, 反有下降趋势, 其中乐学感和自信感下降达显著水平; 情感素质与学习成绩的自我评价、父母受教育程度呈正相关; 师生关系良好、教师有情施教对青少年学生各方面情感素质发展具有重要而直接的促进作用。

腹内脂肪与胰岛素抵抗的关系密切,它在形态、脂解等方面不同于皮下脂肪。脂肪细胞分泌的细胞因子在胰岛素抵抗的发生发展中有着重要的作用。明确腹内脂肪致胰岛素抵抗的机制有益于代谢综合征的防治。     

儿童青少年大脑认知功能事件相关电位P_（300）的年龄特征

从发展心理学的角度．对幼儿到大学六个年龄组的儿童青少年进行了事件相关电位Ｐ_（３００）测定．结果发现：反映大脑认知功能的事件相关电位Ｐ_（３００）各成分随着年龄增长而发展的趋势十分明显,从而进一步说明了认知发展的特点与大脑高级神经系统活动功能发展特点的密切关系。     

浅谈《管子》中环境哲学思想

面对着日益严重的环境危机,今天的人们已经逐渐意识到问题的重要性和迫切性。然而,人们对环境问题的认识仍然存在着严重的局限考虑——自然环境。这种片面的认识是不利于环境问题的根本解决。面对今天复杂、多向的环境问题,《管子》可以提供我们一些有益的启示：以＂道＂为核心的有机整体主义自然观和具体的一些自然资源保护措施;包含着经济正义、法律正义等的社会环境思想;心灵和谐的人文环境思想;自然、社会、人文整体主义的＂一体之治＂思想等。

Eye contact does not facilitate detection in children with autism

Eye contact is crucial in achieving social communication. Deviant patterns of eye contact behavior are found in individuals with autism, who suffer from severe social and communicative deficits. This study used a visual oddball paradigm to investigate whether children with high functioning autism have difficulty in detecting mutual gaze under experimental conditions. The results revealed that children with autism were no better at detecting direct gaze than at detecting averted gaze, which is unlike normal children. This suggests that whereas typically developing children have the ability to detect direct gaze, children with autism do not. This might result in altered eye-contact behavior, which hampers subsequent development of social and communicative skills.     

Transformational leadership and customer service: A moderated mediation model of negative affectivity and emotion regulation

Integrating theories from leadership, emotion management, affectivity, and customer service, this study examines how transformational leadership leads to favourable customer intentions via the mediation of service employees' emotion regulation, job satisfaction, and their service performance and via the moderation of employee negative affectivity. Results obtained from data of 204 matched sets of managers, service employees, and customers show that the effect of transformational leadership on amplification of pleasant emotions was conditioned on service employees' negative affectivity. Employee service performance partially mediated the effect of job satisfaction on customer outcomes. Finally, overall results reveal that transformational leadership and amplification of pleasant emotions were more strongly related to the customer outcomes, as mediated through the intervening variables in the model, when negative affectivity was high than when negative affectivity was low. Results have implications for how service workers with negative affectivity can manage their emotions to achieve effective service outcomes through interactions with a leader, how the effect of transformational leadership can be bounded, and how transformational leadership and emotion regulation are relevant to customer service.
