论开展亲属活体供肾移植的风险与对策

肾脏移植是救治终末期肾功能衰竭的最佳手段。亲属活体捐献肾脏是扩大供肾来源的有效手段。当前国内开展亲属肾移植存在伦理、法律和健康风险,主要来自供体和医疗两方面。为防范风险,医务人员应严格审查供受者的血缘关系,签署完整规范的法律文书,进行全面细致的术前评估,制定完善的手术方案。     

住院放化疗肺癌患者生活质量影响因素分析

生活质量研究是近年来肿瘤治疗研究的热点之一。应用生存质量核心问卷（QLQ—C30）及卡氏功能量表,于治疗前、中、后进行问卷式调查,探讨60例经病理证实接受放、化疗的肺癌患者生活质量的影响因素,预测患者预后和远期生存状态,为住院放化疗肺癌的治疗方法提供一个较好的参考标准,对放化疗肺癌的治疗水平和改善生活质量起到了一定的推动作用。     

Bonus of rebate?: the impact of income framing on spending and saving

All income increases a person's absolute wealth, but consumption decisions may be based more heavily on perceived changes in wealth. Change is computed by comparing a current state with a former state, and we predicted that people would be more likely to spend income framed as a gain from a current wealth state than income framed as a return to a prior state. Four experiments confirmed this prediction on people's memory for spending of a government tax rebate (Experiment 1), on unobtrusive self‐report measures of spending an unexpected windfall (Experiments 2 and 3), and on actual spending on items for sale in a laboratory experiment (Experiment 4). These results can be explained, at least in part, by the reference points implied in the framing of income (follow‐ups to Experiments 1 and 4). Discussion focuses on implications for the consumption of other commodities, assessments of risk, and government tax policies. Copyright © 2006 John Wiley & Sons, Ltd.     

检验导出的等值新方法及其表现探讨

该文受Berkson将检验方法用于估计未知参数的启发,根据三个拟合优度统计量导出三种新的求取等值系数的方法,即:平方根等值方法(Square Root criterion,SQRTcrit)、对称相对熵等值方法(Symmetric Relative Entropy criterion,SREcrit)、加权等值方法(Weighted criterion,Wcrit),即Haebara准则的加权式。虽然在被检验的两个分布列很接近时,这三个多项拟合优度检验方法是渐近等价的,然而用它们求取等值系数时,Monte-Carlo模拟结果表明这三种新等值方法的行为表现存在差异。它们之间的差异和随机误差的大小有密切关系,即与项目参数估计的精度有关;还与等值系数A的范围有关。     

Suppose Freud had chosen Orestes instead

Abstract :  The paper argues that the story of Oedipus, however understood, conveys psychic truth of no greater or more central importance to human development than do the stories of many other myths. A distinction is made between sophisticated theories developed out of Freud's original concept of the Oedipus complex, and the adherence by some clinicians to his original sexual theory. The meaning of Sophocles' play Oedipus the King is found to lie in the clash between Oedipus' omnipotent narcissism ( hubris) and the power of the unconscious psyche, rather than in cross-generational sex. Emphasis is placed on the clinical usefulness of understanding all myths symbolically. The Oresteia by Aeschylus is offered as a story about pre-Oedipal (in the Freudian sense) psychic states. This trilogy shows symbolically the developing of an ego, the establishment of moral judgement and the integration of our shadow (the Furies). It also shows the parallel development of structures of law in society to replace instinctive blood feuds. It is suggested that had Freud chosen Orestes instead of Oedipus, the course of both psychoanalysis and of Western society would have had a different emphasis.     

时序信息和空间信息在工作记忆中的分离存储

采用相对新近性判断范式（judgments of relative recency）,通过三个实验探讨了工作记忆中时序信息和空间信息的存储方式及其关系。实验一比较了有无空间线索两种条件下时序信息的记忆绩效,结果发现,有无空间线索并不影响对时序信．E-的记忆。实验二和实验三通过控制刺激呈现的视野范围和减少呈现位置的不确定性来利化空间线索,结果表明,时序信息的记忆绩效也不受空间线索的影响。由此推论,工作记忆中的时序信息和空间信息是分离编码存储的,加入空间线索并不能提高时序信息的记忆绩效。     

Did the Market Depress Happiness in the US?

Robert Lane is a seasoned critic of American consumer society. His latest book summarizes many of the arguments brought up earlier and contributes new data about developments in income, companionship and happiness in the USA between 1972 and 1994. Lane notes a considerable rise in incomes over these years and claims that companionship and happiness have declined. He attributes this decline to market forces that emphasize money at the expense of intimate bonds, resulting in a weakened capacity to deal with stress.This review challenges two of the book's hypotheses. First, it shows that happiness did not decline in the USA in these years, but was actually quite stable. Second, it mitigates the assertion that companionship has dwindled and notes that money making and companionship are not necessarily antithetical.Still, Lane could be right. Possibly market forces did depress happiness and possibly that loss was offset by improvements in other fields, like increased freedom or better health care, such as better treatment for mental problems. If so, Lane's message is that Americans could have been happier than they ultimately were.     

人眼深度运动知觉的研究

人类的深度运动知觉,是通过检测二维平面内的相对运动而形成的。本文在心理物理学实验基础上,揭示该机制的数学与生理学实现形式。视觉系统中存在对视平面内的相对运动敏感的神经元,构成深度运动的检测机制,产生单眼深度运动知觉与双眼深度运动知觉。在心理学上,视觉利用物体视角变化及大小知觉的恒常性判断深度运动。文中还初步讨论了人类的深度运动知觉与蜜蜂,家蝇等昆虫的深度运动知觉的区别。     

Optimism and Revolt of the Oppressed: A Comparison of Two Polish Jewish Ghettos of World War II

One World War II Jewish ghetto that revolted, the Warsaw Ghetto, is compared to one that did not, the Lodz Ghetto, in order to examine the causes of violent resistance. This structured focused comparative method (George, 1979) illuminates problems with previous explanations for revolt and nonrevolt in Jewish ghettos and suggest psychological variables that might have led to or precluded organized violence. Specifically, it appears that these two ghettos differed in their perceptions about their future. The residents of the Warsaw Ghetto believed they had no hope of survival while residents of the Lodz Ghetto remained optimistic. These differing perceptions seem to have led to the different outcomes. Possible causes of these percetpions are also discussed.     

Short-component multiple schedules: effects of relative reinforcement duration

Pigeons were exposed to multiple variable-interval 2-min variable-interval 2-min schedules of food presentation in which relative duration of food presentation was manipulated. When components alternated every 5 sec and were scheduled on separate response keys, relative response rates closely matched relative reinforcement duration in three of four pigeons. On the other hand, relative response rates were insensitive to relative reinforcement duration when components scheduled on a single response key alternated every 5 sec, and when components scheduled on separate response keys alternated every 2 min. Thus, both rapid alternation and spatial separation of components were necessary to produce approximate matching of relative responding to relative reinforcement duration. This finding contrasts with previous findings that only rapid component alternation is necessary for matching when relative rate of reinforcement is manipulated.
