缺位与越位的思考——医疗保健体制改革的定位

政府的缺位和医院的越位是目前医疗体制改革的症结所在。政府将医院推向市场,意味着政府放弃医疗的社会保障职能。医院失去政府的约束和支持,逐利将成为其必然行为。平价医院只是缓和矛盾的一时之计,只要医院不退出市场,看病难、看病贵就难有灵丹妙药,医患关系也将难以和谐。

4~6岁汉语儿童正字法意识的萌芽与发展

研究旨在考察汉语学龄前儿童正字法意识的发展情况。在某中等城市一所幼儿园随机选择4岁、5岁、6岁三个年龄段的儿童各31、37、34名。实验一使用汉字、韩文和日文（平假名）作为实验材料探查学龄前儿童的汉字特异性意识;实验二使用上下结构、左右结构的真字、假字和非字考察学龄前儿童的部件位置意识。实验结果显示：（1）三组儿童都能区分日文和汉字,5岁左右儿童这种能力达到成熟。4岁儿童不能区分汉字和韩文,直到6岁,辨别汉字和韩文的能力也没有发展成熟。（2）三组儿童都能意识到假字符合正字法规则,但拒绝非字的能力在学前期尚未发展成熟,儿童在学前期不具备部件位置意识;6岁儿童更容易拒绝上下部件位置颠倒的非字。     

空间再定向任务中心理表征的多样性——来自虚拟现实实验的证据

成人和儿童完成空间再定向的具体过程与内在机制一直是研究者们关注的问题,在空间中是否形成了关于环境的整体表征是其中的一个关键。研究者们的观点并不一致,研究结果也提供了不同的证据。使用传统的空间再定向任务在此问题上难以得到明确的结论。本研究采用虚拟现实技术,让被试在虚拟现实环境中观察所在空间,然后直接向被试呈现空间的俯视视角并要求完成位置再认。通过对正确率和反应时的模式分析,发现被试反应可以划分为三种类型：整体的、独立于视角的心理表征（各方向均为高正确率低反应时）;整体的、依赖于方向的心理表征（正确率和反应时在不同方向上差异显著）和视角匹配的心理表征（各方向上均为低正确率）。三种不同的表征形式在人群中同时存在,并且在同一个体身上表现出不稳定性。     

藏-汉读者汉语歧义句加工的歧义效应及语境促进效应

采用眼动技术,通过两个实验,考察藏-汉读者阅读汉语歧义句时的歧义效应以及语境在句子歧义消解中的作用。结果发现:藏-汉读者在阅读汉语歧义句时存在歧义效应; 语境对歧义消解起促进作用,表现为,当语境置于歧义句之前或语境意义偏向歧义句主要意思时,藏-汉读者对歧义句的加工更容易。并且,歧义效应和语境促进效应贯穿于早期阶段到晚期阶段的整个句子加工过程。     

Historical and Philosophical Reflections on the Success of the Chinese Path

The success of the Chinese path is not an accidental “miracle,” but an inevitable result that conforms to the historical law. In practice, it is inseparable from the diligent and creative work of the Chinese people, the timely formulation of policies by the Communist Party of China and governments at all levels seeking truth from facts, and the change and improvement of policies according to the changes of the situation. In addition to these practical reasons, the success of the Chinese path has very farreaching historical and cultural reasons, which are the metaphysical basis of the Chinese path in a more philosophical sense. Unlike Western culture, which is in a sense a culture of ultimate entities, deep Chinese culture is based on a metaphysical reflection of the existence of a relational system, whereas European culture and Middle Eastern Muslim culture are based on the “origin” and “source” of a single entity or a single “God.” In the West, “God” is the creator of mankind; in China, “heaven” or “emperor” is actually binga symbol of a ruling relationship and has an interactive relationship with the people, which is a very subtle interdependent relationship. It is this concept of “relationship” about the world that endows the Chinese spiritual world with a special resilience on concept of time and historical behavior, because “relationship” can be adjusted and is constantly changing.     

On the nature of consonant/vowel differences in letter position coding: Evidence from developing and adult readers

In skilled adult readers, transposed‐letter effects (jugde ‐JUDGE ) are greater for consonant than for vowel transpositions. These differences are often attributed to phonological rather than orthographic processing. To examine this issue, we employed a scenario in which phonological involvement varies as a function of reading experience: A masked priming lexical decision task with 50‐ms primes in adult and developing readers. Indeed, masked phonological priming at this prime duration has been consistently reported in adults, but not in developing readers (Davis, Castles, & Iakovidis, 1998). Thus, if consonant/vowel asymmetries in letter position coding with adults are due to phonological influences, transposed‐letter priming should occur for both consonant and vowel transpositions in developing readers. Results with adults (Experiment 1) replicated the usual consonant/vowel asymmetry in transposed‐letter priming. In contrast, no signs of an asymmetry were found with developing readers (Experiments 2–3). However, Experiments 1–3 did not directly test the existence of phonological involvement. To study this question, Experiment 4 manipulated the phonological prime‐target relationship in developing readers. As expected, we found no signs of masked phonological priming. Thus, the present data favour an interpretation of the consonant/vowel dissociation in letter position coding as due to phonological rather than orthographic processing.     

The association for behavior analysis international position statement on restraint and seclusion

A task force authorized by the Executive Council of the Association for Behavior Analysis International (ABAI) generated the statement below concerning the techniques called restraint and seclusion. Members of the task force independently reviewed the scientific literature concerning restraint and seclusion and agreed unanimously to the content of the statement. The Executive Council accepted the statement, and it was subsequently approved by a two-thirds majority vote of the general membership. It now constitutes official ABAI policy. The position statement is posted on the ABAI Web site (www.abainternational.org/ABA/statements/RestraintSeclusion.asp). The purpose of the position statement is to provide guidance to behavior analysts and other professionals interested in the position of ABAI on these controversial topics. In extreme cases, abuses of procedures erroneously used in the name of behavior analysis are not defensible. On the other hand, behavior analysts acting ethically and in good faith are provided with guidelines for sound and acceptably safe practice. To the extent that behavior-analytic positions influence public policy and law, this statement can be presented to officials and lawmakers to guide informed decision making. At the conclusion of the document, a bibliography is provided of articles and presentations considered by one or more task force members in developing the position statement.     

Whom to help? Immediacy bias in judgments and decisions about humanitarian aid

People exhibit an immediacy bias when making judgments and decisions about humanitarian aid, perceiving as more deserving and donating disproportionately to humanitarian crises that happen to arouse immediate emotion. The immediacy bias produced different serial position effects, contingent on decision timing (Experiment 1). When making allocation decisions directly after viewing to four emotionally evocative films about four different humanitarian crises, participants donated disproportionately more to the final, immediate crisis, in contrast, when making donation decisions sequentially, after viewing each of the four crises, participants donated disproportionately to the immediate crisis. The immediacy bias was associated with “scope neglect,” causing people to take action against relatively less deadly crises (Experiments 2 and 3). The immediacy bias emerged even when participants were warned about emotional manipulation (Experiment 3). The immediacy bias diminished over time, as immediate emotions presumably subsided (Experiment 2). Implications for charitable giving, serial position effects, and the influence of emotion on choice are discussed.
