No Time of Day Modulation or Time Stamp on Multiple Memory Tasks in Rats

Various demonstrations of “time stamp” effects in the animal learning literature have reinforced the idea that circadian information is encoded as part of a combined internal/external representation of context and that this contextual information is utilized for complex retrieval processes supporting memory. The goal of the present series of experiments is to assess this idea by manipulating training/testing circadian times on a battery of learning and memory tasks commonly used in the rodent. The data obtained from five experiments using four different learning and memory paradigms provide no evidence for “time stamp” effects on place memory, context memory (aversive or appetitive), or S-R habit learning.     

A Latent Variable Framework for Power Estimation Within Intervention Contexts

This paper presents a latent growth SEM approach for the estimation of treatment effects, and power to detect such effects, within a true experimental design setting in which subjects are randomly assigned to treatment and control conditions. Power estimation is a critical component of intervention experiment design and the testing of their results. Although researchers have become increasingly sophisticated in applying tests for statistical significance in intervention contexts, few are aware of the power of these tests. The issues raised in this paper are not new; however, reminding researchers to consider these points is important. Exactly how the researcher handles these issues will depend on the questions asked and the resources available, as well as other considerations. Discussion underscores the relationship between the reliability of a study's measures and concomitant increases in power obtained within the SEM framework.     

临床医学与人文素质

遗传研究已经测定出人类基因序列,人的克降技术如此完备,克隆人呼之欲出。但是,人类并没有因为高科技而摆脱身心的负担,反而更为焦虑。人类受自身生物结构的限制,对世界的了解借科学的发展而发展,因而对世界的认识既受限制,又无止境,临床医学更加需要人文主义精神,要求医生把病人更多地看作是社会的人,有着非常复杂的心理需要,而不仅仅是生物学意义上的人。临床医生的人文素质培养和要求是当务之急。     

样例的子目标编码对新问题解决中原理通达的作用

通过 3个实验 ,分别研究了样例的不同编码对消除由于表面概貌和表面对应变化对原理通达带来的消极影响的作用以及样例学习中原例概化的形成阶段。实验结果表明 :样例解题步骤的子目标编码有助于消除由于表面内容变化对原理通达带来的消极影响 ;子目标学习使学习者在样例学习阶段就形成了关于原理的概化。     

Spiritual Development Across the Adult Life Course: Findings from a Longitudinal Study

Longitudinal data spanning early (30s) and older (late 60s/mid-70s) adulthood were used to study spiritual development across the adult life course in a sample of men and women belonging to a younger (born 1928/29) and an older (born 1920/21) age cohort. All participants, irrespective of gender and cohort, increased significantly in spirituality between late middle (mid-50s/early 60s) and older adulthood. Members of the younger cohort increased in spirituality throughout the adult life cycle. In the second half of adulthood, women increased more rapidly in spirituality than men. Spiritual involvement in older age was predicted by religious involvement and personality characteristics in early adulthood and subsequent experiences of negative life events.     

学习支持对儿童在多媒体语境中学习英语词汇的影响

该研究旨在考察中文翻译与主题提示两种学习支持对儿童在多媒体语境中学习英语词汇的作用,为此设计了三种学习条件：无支持条件、中文翻译条件和中文翻译 主题提示条件。对学龄初期儿童在上述三种学习条件下学习英语词汇的过程和结果进行的考察和分析表明：儿童在无支持条件下的学习效果较差;中文翻译可以明显促进儿童对语句的理解,但无法提高儿童对目标词的掌握;中文翻译 主题提示条件下儿童对单词语义的掌握最好,他们表现出了较多的跟读行为,并更倾向于认为学习任务较为容易。     

公共行政伦理价值定位与规范体系

加强公共行政伦理建设,是加强政风建设、建设廉洁勤政务实高故政府、建设高素质公务员队伍的基本途径。因此,必须对公共行政伦理进行价值定位,借鉴国外公共行政伦理建设的经验,建构中国当代公共行政伦理的规范体系。     

关于克隆人试验与伦理学的三原则

由于克隆人试验的对象是人的活细胞,不是人的胚胎;并且由于人只能有限地决定自己的未来,根本无法决定自己的出生;同时由于基因诊断和修复有助于新生儿的健康,因而克隆人试验既不会伤害任何人的生命体,也不会侵犯任何可能出现的克隆人的自主权和平等权,进而不会违反伦理学的三原则。     

对以边沁、密尔为代表的功利主义的分析批判

边沁的功利主义为苦乐原理、效果论和功利原则这样三个理论基点所构成。这是一个有着内在逻辑困境的三原理。苦乐原理由于没有进行内在的质的区分,为密尔所修正,但密尔的修正突出了苦乐原理与效果论的内在不一致;同时,密尔以自我牺牲来补充功利主义,又暴露了功利主义原则的内在矛盾。还有,密尔以平等权利来为功利主义的最大幸福原理辩护,恰恰表明功利原则并非是可以成为一个理论的基础性原则或终极原则。斯马特的行动功利主义则进一步暴露了功利主义的非正义性特性。功利主义的这样三个典范表明仅仅诉诸功利原则无从走出内在逻辑困境。布兰特援引认知理论以及道义论原则,笔认为这才使功利主义从其困境中走出。     

Science and Religion: Getting Ready for the Future

I explore three challenges for the current dialogue between science and religion: the challenges from hermeneutics, feminisms, and postmodernisms. Hermeneutics, defined as the practice and theory of interpretation and understanding, not only deals with questions of interpreting texts and data but also examines the role and use of language in religion and in science, but it should not stop there. Results of the post‐Kuhnian discussion are used to exemplify a wider range of hermeneutical issues, such as the ideological potential of scientific concepts, the dynamics of interdisciplinarity, and the significance of the socioeconomic situatedness of science and religion. Feminist research analyzes the consequences of the interplay of masculine, feminine, and gender typologies in religion and science. Examples from the history of science as well as current scientific conceptualizations indicate that beliefs in the inferiority of woman form part of our inherited scientific, religious, and metaphysical framework. It is argued that postmodernism in its most constructive form shares the best fruits of modernity, especially of the Enlightenment, while avoiding some of its most serious mistakes. In conclusion, reflecting on the three publics engaged in the dialogue between science and religion—academe, religious communities, and societies—I offer constructive suggestions and critical observations concerning the future of this dialogue.
