药价“虚高”:成因、结果分析与对策探讨

药品价格“虚高”已成为近年来药品市场中的一个突出问题。通过考量药价“虚高”的成因,并从实证的角度分析药价“虚高”的结果———“有效需求人数”和“消费者剩余”的减少,提出一些建议。     

医药代表现象与药品价格政策的改革

探讨医药代表所引出的药品价格政策等问题,通过分析医药代表发生阶段性错位的原因,引出对药品价格改革的思考.我国的药品价格虚高是导致医疗市场失控的根本原因,医药代表的错位只是一种表现.根除这种错位必须首先解决药品价格虚高的问题.

降低药费支出如何可能

政府人为压低医疗服务价格导致的"以药补医"机制赋予了医疗机构抬高药价、谋取售药利润的合法权力,而公立医疗机构在药品零售环节上的双向行政垄断地位使其具有足够的能力高价卖药以获得高额卖药收益,进销差价率管制则进一步诱导医院进销高价药,而单独定价政策加之宽松的新药审批制度为药厂提高药品批发价、医院购销高价药提供了便利.所有这些问题源于政府管制的失当."收支两条线"改革根本无助于实现控制药品费用并促进医院合理用药的目标.降低药费支出的根本措施是消除价格管制,实现医疗服务市场定价、消除"以药补医"体制,消除公立医疗机构对药品零售的垄断,最终实现医药分开.     

"医药分业"改革的经济学分析

目前,我国药品监督管理机构正在推行"渐进式的医药分业"政策,目标是将药品价格总体下降26%～30%,将每年469亿元～547亿元的药品毛利化作医疗服务收费标准的调整幅度,以后医疗服务收费标准按物价指数逐年调整.但在现有条件下执行这一政策,表面上医疗机构是直接的利益受损者,但事实上广大的药品消费者或支付者将为之埋单而成为利益受损者,药品生产者和流通渠道才是这一政策的真正受益者,政府也将面临提高医疗服务收费标准或增加医疗机构补偿的两难抉择.     

论从药品到毒品的"角色"转换

毒品与药品有着密不可分的联系,毒品来源于药品但又不同于药品.具有依赖性的药品一旦流入非管制渠道,用于非医疗目的,在社会上泛滥便成为毒品.因此,对有依赖性的药品需要严格管理并合理地使用.     

易道辩正

易道是易学思想的精髓或内在精神,其最根本的特征是所谓的“一阴一阳之道”。作为易学结构基元的易卦卦象符号,与阴阳观念具有先天性的亲和力,从而使得阴阳观念有了一个可以符号化表征的形式系统。在汉代,阴阳五行与易学成为一个统一的有机整体。两汉的象数理论试图将易道(天道)完全形式化努力的最终结果是“入于礻几祥”,成为一套牵强附会的繁琐哲学。魏晋以后,诸如“时”、“中”一类具有明显的个人独知默会、参悟修证意义的命题,逐渐成为一阴一阳、生生不息的“易道”最为生动的表征。道之真谛,若以易理言之,就是“自强不息”,“与时偕行”。     

"全球伦理"与"文明的冲突"

自美国9.11恐怖袭击事件后,塞缪尔.亨廷顿关于“文明冲突”的理论引起人们高度兴趣。以宗教为核心的文明之间的冲突真的难以化解吗?汉斯.昆的“全球伦理”观点对此提出挑战。本文将浅析一下“全球伦理”,及其化解“文明冲突”的可能性。     

方术迷信的"灵验"揭秘

方术作为中华神秘文化的一个重要的组成部分,是一种既不同于宗教又与宗教有联系的企图借助于“鬼神”等神秘力量来消灾免祸、延年益寿、添财加福的可操作性的东西,如八卦术、算命术、风水术、占梦术、测字术、巫术等。 方术尽管是唯心的不可相信的东西,在历代也遭到了一些人的攻击和批判,然而为何屡不绝迹,有时甚至风靡一时、影响很大,即使在今天仍然有其市场呢?其中一个重要的原因在于一些人认为方术“灵验”。 方术“灵验”的原因是什么?到底是哪些因素     

"Psychotherapy" versus "treatment"

Presents a comment on "Psychological treatments" by D. H. Barlow. Barlow proposed that we distinguish between the terms "treatment" and "psychotherapy." The author believes that not only is the distinction unnecessary, but that its implications could have negative consequences for the field of clinical psychology. It is the proposed distinguishing feature that treatments are "specifically tailored to the pathological process that is causing the impairment and distress" that is most problematic. Clinical psychology does not need a distinction that further exacerbates the split between researchers and practitioners.     

"Enmeshment" and "Fusion"

The paper examines two related concepts utilized by two different schools of family therapy. Any family seen to be "enmeshed" is also seen as "fused," and vice versa. The difference in the level of focus, on the "system containing the individuals" (structural) or the "individual in the system" (fusion), determines the difference in therapeutic approach of these two schools.     

"本体论"与"伦理学"--形而上学的两个向度

形而上学有两个密切相关的内在向度,就是本体论向度与伦理学向度.在哲学史上,哲学家们之所以在"追求形而上学"的同时,又总是"反形而上学",并非是人们的形上本性出了问题,而是因为人们总是将形而上学视为单纯的"一维性",总是用一个向度来取代或遮蔽另一个向度.而所谓的"后形而上学思想",也并不是消解了形而上学,而是指形而上学从"本体论向度"转向了"伦理学向度".     

“对的”与“好的”

什么是“对的”,和对它的证立,是道德哲学中具有争议性的核心问题,也是效用主义和道义论间的主要差异之所在。统合效用主义对于“好的就是对的”这个陈述有一套完整周延的说法。而道义论对这个问题的证立不够周延或没有足够的说服力。     

The development of children's understanding of "because" and "so"

Children's (5 years, 8 months to 8 years, 4 months) comprehension of "because" and "so" was assessed on both enactment and sentence completion tasks. The use of a within-subject design permitted performance on each task to be interpreted in terms of performance on the other. The pattern of results provided evidence against a componential model for the acquisition of causal connectives. This model holds that the two meaning components (cause, order) are acquired separately, with the order component being acquired several years later than the causal component. The results also were in accord with predictions derived from a contextual model of children's developing understanding of terms expressing logical relationships. This model posits that the understanding of relational terms is initially context dependent, such that children can understand relational terms when they express familiar relationships, but experience difficulty in forming representations of novel relationships solely on the basis of linguistic input. The lexical components of because and so are understood during the context-dependent stage, and the transition from context-dependent to context-independent understanding does not reflect further lexical development, but rather increasing facility in dealing with decontextualized linguistic input.     

Comparison of two theories of "ratio" and "difference" judgments

This article examines the hypothesis that judges compare stimuli by ratio and subtractive operations when instructed to judge" "ratios" and "differences." Rule and Curtis hold that magnitude estimations are a power function of subjective values, with an exponent between 1.1 and 2.1. Accordingly, the two-operation model tested assumes magnitude estimations of "ratios" are a comparable power function of subjective ratios. In contrast, Birnbaum and Veit theorize that judges compare two stimuli by subraction for both "ratio" and "difference" instructions and that magnitude estimations of "ratios" are approximately an exponential function of subjective differences. Three tests were used to compare the theory of one operation with the two-operation theory for the data of nine experiments. The results strongly favor the theory that observers use the same operation for both instructions.
