伦理生态视阈中的医学伦理精神诠释与建构

基于本体思维的"原子式探讨"不能实现医学伦理精神的现代建构。由本体伦理思维到伦理生态思维的道德哲学范式转换为探讨医学伦理精神提供了新的思维向度和价值资源。伦理生态视阈中的医学伦理精神是一个多维、多层次的张力系统,其建构在于:重建伦理主体的自身精神生态、"医学伦理—卫生经济"政策生态、医学伦理—社会文化生态。     

我国公共卫生中的伦理学问题

在公共卫生研究中重点探讨了伦理审查、研究对象选择、知情同意、保护研究对象隐私、对研究对象的适当补偿等方面的伦理学问题;在公共卫生实践中重点探讨了传染病防治、疾病监测、计划免疫、疾病筛查及卫生资源配置领域中的伦理学问题。重视这些问题并参照一定的伦理学原则将有助于解决问题,更好地促进公共卫生事业的发展,促进人群健康。     

整体语境和局部语境对代词理解的影响

通过眼动实验,考察了语篇理解中整体语境和局部语境对代词理解的影响。实验一是预备实验,发现名词与动词词组之间关系的典型性不同,整合的速度也不一样。实验二发现,代词的理解不是一次完成的,代词理解的初期受整体语境的语义偏向影响,而不受局部语境的影响。在第二阶段主要受到局部语境的影响。代词的理解过程比较符合Cook（2004）所提出的两阶段模型     

工作记忆与汉语歧义句加工的眼动研究

以符合“VP+N1+的+N2”格式的述宾型歧义短语组成的句子为材料,采用2×2的混合设计,即2(工作记忆广度：高、低)×2(续接方式：偏正、述宾),采用眼动记录法,考察被试对歧义短语的语义加工过程。结果发现：（1）在无前语境的暂时句法歧义句中,不同的续接方式在句子的最初加工过程中的作用不显著,而在最终的理解过程中作用显著。（2）工作记忆高有利于句子的理解,但对歧义短语的两种意思的提取和保持的作用不显著。     

我国妇幼保健机构公共卫生属性淡化的机制研究

妇幼卫生是公共卫生体系的重要组成部分,妇幼保健机构是妇幼卫生工作的实现主体,为了促进我国妇幼保健机构的健康和可持续发展,提高妇女、儿童健康水平,通过对妇幼保健机构的社会功能、行为动因和行为特征的系统分析,构建出妇幼保健机构公共卫生属性淡化的作用机制模型.公共卫生的实质是公共政策,建议政府要实现市场机制与政府宏观调控的有机结合,促进妇幼保健事业健康发展.     

项目突显方式对视觉搜索策略的影响

搜索策略是将视觉注意导引到目标最可能出现位置的直接认知控制。本研究采用眼动跟踪技术与视觉搜索时间——鼠标点击时间的分离技术,探讨计算机视觉界面不同项目突显方式下的搜索策略问题。结果表明：（1）有无项目突显方式、不同的突显有效性水平,被试采用了导向式和序列式两种不同的搜索策略;（2）被试采用导向式搜索策略时,被试在第一个感兴趣区域首注视点百分比小于58.3％,在视觉搜索过程中的注视点数量明显较小、扫视轨迹长度和注视时间明显较少;（3）被试采用序列式搜索策略时,被试在第一个感兴趣区域首注视点百分比大于58.3％,在视觉搜索过程中的注视点数量明显较多、扫视轨迹长度和注视时间明显较长;（4）采用导向式的视觉搜索策略能显著减少被试的视觉搜索时间,提高视觉搜索的绩效,但不能显著减少被试的鼠标点击时间;（5）因为视觉界面上突显的设置改变了用户的搜索策略,所以提高了视觉搜索绩效。     

Social representations of organ donors and non‐donors

This paper illustrates the empirical investigation of social representations by means of photographs as stimulus material and the technique of correspondence analysis to study the resulting data. The research was part of a campaign carried out to promote organ donation in Malta. The study tries to find out whether a public communication campaign could change perceptions. Five focus groups were held before the campaign and another five, two months after the campaign. Part of the data collected through these focus groups was analysed using correspondence analysis. The results showed that before the campaign, donors were generally perceived to be either young or important people or public personalities. After the campaign, donors were perceived more to be ordinary family people, educated, generous and religious. On the other hand, before the campaign, non‐donors were seen as conservative, uncouth and uncaring, whereas after the campaign non‐donors were generally perceived to be older, uninformed and uneducated people.

自闭症幼儿自主性共同注意的实验研究

为探索和发现自闭症幼儿的自主性共同注意的特征,以6名自闭症幼儿,以及在心理年龄与之匹配的弱智和正常儿童各6名作为研究对象,以实验和准实验的方法,进行此研究。同时还以秒为单位对实验过程与结果进行编码分析。结果表明,自闭症幼儿的自主性视觉方向所及目标物多于人,而人的目标中叉更多地锁定同伴而非教师。自闭症幼儿在唤起他人共同注意时多以“拉”和“抱”来替代指点行为。自主性共同注意的发生率与情绪有密切关系。     

图画与中、英文词识别加工的眼动研究

以图画、中文词和英文词的一系列变式为实验材料,使用眼动技术采集被试在观察上述材料时的眼动参数。实验结果显示：人眼对图画、中文词和英文词三种材料识别加工的眼动模式不同。在注视时间方面,图画的注视时间最短,英文词的注视时间最长,中文词的注视时间居中;在眼跳距离方面,图画的眼跳距离最大,英文的眼跳距离次之,中文的眼跳距离最小。在反应时方面,人眼对图画的反应时最短,英文词最长,中文词居中。     

Image Events, the Public Sphere, and Argumentative Practice: The Case of Radical Environmental Groups

Operating from the assumption that a primary dynamic of contemporary public argument involves the use of visual images the authors explore the argumentative possibilities of the `image events' (staged protests designed for media dissemination) employed by radical ecology groups. In contextualizing their discussion, the authors offer an analysis of the contemporary conditions for argumentation by describing the character and operation of public communication, social problem creation, and public opinion formation in a mass-mediated public sphere. The authors argue that image events are a form of postmodern argumentative practice, a kind of oppositional argument that creates social controversy, and animates and widens possibilities for debate. They further suggest that image events are a postmodern form of argument involving acts of protest which deliver images as argumentative fragments. Employing the tools of traditional argument theory the authors describe how images are capable of offering unstated propositions and advancing indirect and incomplete claims in ways that function to block enthymemes and advance alternatives. In concluding, the authors discuss the implications of image events for our understanding of the public sphere and the possibilities for argumentation in a postmodern age.
