步入涅槃还是走向终结?——对当代医学困境的原点审视和深层反思

当代医学在享受基因时代“圣餐”的同时,也在步入一个危机频发的“问题时代”。从原点审视,造成其危机和困境的“本因”,是其核心价值系统及其动力体系的根本缺陷所致,其基本的生命观、疾病观陷入到诸多哲学困惑和认识误区,其治疗观的“对抗性思维”更是有违自然伦理的法度,这是当代医学走向更高理论平台的战略切入点。     

全社会共同努力,在发展中实现卫生公正

“公正”是科学发展观的重要内容,是卫生系统的主要价值取向,实现公正是医药卫生界的神圣职责。目前,在发展中实现卫生公正已经刻不容缓。我们必须以政府为主导,坚持以人为本和卫生公正,树立扶贫济困的社会风气,共同努力,采用多种措施实现卫生公正。     

RELIGION VERSUS SCIENCE: THE CONFLICT IN REFERENCE TO TRUTH VALUE,NOT CASH VALUE

Abstract. The rift between science and religion needs to be assessed not merely on pragmatic grounds, on the basis of the effect of scientific versus religious beliefs on people's behavior, as John Caiazza's essay does, but also and above all in regard to the cogency of the respective beliefs in reference to what we can reasonably assume is the true face of reality. About such truth value, the conflict is not irremediable; there are elements of belief regarding the nature of reality that are strikingly similar regardless of whether one arrived at them on the basis of faith in revealed knowledge or on the basis of knowledge acquired by reasoning from or in reference to experience. Two such items are selected here by way of example: belief that in certain states of mind and consciousness individuals can experience union with something larger or deeper than themselves, and belief that the universe we inhabit is the result of an original creative act.     

Group Attachment and the Reduction of Value-Driven Ambivalence

This article analyzes the effects of value-driven ambivalence and group attachment on response variability in public attitudes toward campaign finance reform. The analysis demonstrates that group attachment, when activated by affective cues, moderates the effects of ambivalence on response variability. By tipping the balance of considerations in one direction or the other, group attachments make it easier for ambivalent respondents to make tradeoffs between competing values during policy choices and, as a result, dampen response variability. Methodologically, the results offer an important cautionary note about the use of linear ambivalence scales by calling into question the assumption that indifference is an intermediate state between preference and ambivalence.     

谁更愿意购买绿色产品？认识绿色消费者

绿色消费虽然备受关注但消费者积极性却不高,这可能和个体差异性有关。为了考察绿色消费的积极性,本研究从个体差异的视角出发,引入购买时间距离这一变量,以揭示面对绿色产品的矛盾性消费者究竟更愿现在购买还是将来,决策模式是否会存在个体差异。研究发现,时间距离调节绿色消费观与产品购买意愿的关系,而产品价值感知部分中介了该调节作用。具体来说,绿色消费者不会受到时间框定的影响,而非绿色消费者则表现出时间框定效应即更倾向于在将来而不是现在购买绿色产品;这是因为绿色消费观以自上而下的方式影响绿色消费者动机加工,使绿色产品的价值感知较为稳定,而非绿色消费者的价值感知则根据购买时间距离的不同而变化。研究结果说明在生态文明建设日益紧迫的当下培育个体绿色消费观具有重要的意义。     

Can the West Save the East? Intrinsic Value and the Foundation of Chinese Environmental Ethics

Intrinsic value in nature is a key concept in professional environmental ethics literature in the West. Western scholars such as Holmes Rolston III and Paul Taylor argue that the philosophical foundation of environmental ethics should be based on the concept of intrinsic value in nature. Influenced by this concept, some influential Chinese environmental ethics scholars such as Yu Mouchang and Lu Feng argue that the foundation of environmental ethics in China should be based on the concept of intrinsic value in nature. This paper holds that the metaphysical, epistemological and ethical meaning of intrinsic value in nature is the legacy of Western philosophical traditions, which is in conflict with the Chinese philosophical traditions. Meanwile, the paper argues that the Daoist conception of living in harmony with nature can become the foundation for Chinese environmental ethics. The Daoist conception of living in harmony with nature is based on aesthetic appreciation of nature and people’s participation in the beauty of nature.     

Must Differences in Cognitive Value be Transparent?

Frege’s ‘differential dubitability’ test is a test for differences in cognitive value: if one can rationally believe that p while simultaneously doubting that q, then the contents p and q amount to different ‘cognitive values’. If subject S is rational, does her simultaneous adoption of different attitudes towards p and q require that the difference between p and q (as cognitive values) be transparent to her? It is natural to think so. But I argue that, if attitude anti-individualism is true, then rational differential dubitability does not presuppose that differences in cognitive value are transparent. The significance of this argument lies in what it tells us, both about the notion of cognitive value and its relation to the differential dubitability test, but also about the prospects for a Burge-type position which aims to combine attitude anti-individualism with a (qualified) reliance on the differential dubitability test.

中国城区青少年对广告价值的评价:前因和后果

通过对北京市7所中学366名学生的调查,探讨了青少年对广告价值的评价以及何种因素影响青少年对广告价值的评价,广告价值的评价是否会进一步影响其决策等问题。运用AMOS 4.0建立结构方程模型对研究假设进行检验,结果表明：（1）青少年对广告价值的评价直接影响到他们的决策意图;（2）在探讨广告价值的影响因素时发现,对广告的知觉因素（信息性和娱乐性）和青少年对广告以及广告商的社会认知（观看广告的社会动机和对广告劝服技巧的认识）对广告价值的影响作用也十分显著,信息性、娱乐性与社会动机都对广告价值产生积极影响,而对广告劝服技巧的认识则对广告价值产生显著的负面影响     

Toward a Mechanistic Understanding of Human Decision Making: Contributions of Functional Neuroimaging

ABSTRACT— This article considers the contribution of functional neuroimaging toward understanding the computational underpinnings of human decision making. We outline the main processes likely underlying the capacity to make simple choices and describe their associated neural substrates. Relevant processes include the ability to encode a representation of the expected value or utility associated with each option in a decision problem, to learn such expectations through experience, and to modify action selection in order to choose those actions leading to the greatest reward. We provide several examples of how functional neuroimaging data have helped to shape and inform theories of decision making over and above results available from traditional behavioral measures.     

不同条件下拟合指数的表现及临界值的选择

在本模拟研究中设计了6种样本容量,6种因子载荷,和4种评分等级,并考察了正态和非正态分布两种情况。采用的错误模型为参数误置（真模型中每个因子各由5个题目来测量,错误模型中则是第一个因子由6个题测量,另两个因子各由4个和5个题来测量,即有一个因子载荷被误置）模型。结果发现（1）样本量、载荷量、评分等级数和分布形态都对GOF的取值确有影响。其中分布形态的影响最大。NNFI、IFI在不同条件下的平均值是最稳定的,其次是CFI、RMSEA和SRMR。它们都算是值得推荐的GOF,尤其是NNFI和IFI。（2）在正态分布中,当样本量≥1000时,根据NNFI、IFI、CFI、RMSEA、SRMR对模型是否拟合做出判断时有很低的两类错误率,在样本量<1000时则不理想。在偏态条件下无论选择哪个GOF两类错误率都很高。（3）采用2指数策略在很多情况下也不能显著降低两类错误率。（4）由于在数据分布非正态,或正态但样本量<1000时是难判断模型是否拟合的。因此我们提出了2界值策略。即为每个GOF确定上下两个界值。低于下界值时可判断模型是不正确的,而高于上界值时则可判断模型是正确的。GOF取值处于上下界值之间时难以判断模型是否拟合,只能说越高拟合的可能性越大。这时就要通过跨样本验证和增加样本量来确定模型是否正确
