An ethnomethodological clarification of Husserl's concepts of “regressive inquiry” and “Galilean physics” by means of discovering praxioms

This paper offers an ethnomethodological clarification of Husserl's concepts of Galilean physics and regressive inquiry. It employs the reader's textual-practical operationalization of these concepts. With the use of a simple optical prism as a perspicuous case of a scientific instrument, the reader will be asked and instructed to make a self-reflexive inquiry into the practical contingencies of the prismatic field of reflection. The reader will discover that the geometric structures of the reflective field of the prism is an achievement and formalization of the reader's own operatlonalizations. I named these discoverable discovering operationspraxioms or practical axioms — the pre-scientific contingencies of the geometric structures of prismatic reflection.I would like to thank Mike Lynch, Eric Livingston, George Psathas and Shelley Schweizer-Bjelic for their comments.     

认知操作和认知方式与生态文化因素的关系

采用认识测试、查阅人类学资料、现场调查和谈话等多种方法探讨了我国不同生产方式、不同地区和不同民族４６０名成人的分析综合的认知操作和认知方式及其与生态文化因素的关系．认知测试分数的８×２×３的ＡＮＯＶＡ协方差分析表明,在分析操作水平上存在着显著的组间差异、性别差异、年龄差异和协变量（现代化影响）的效应;在综合操作上,存在着显著的组间差异、年龄差异和协变量效应;在认知方式上,存在着显著的组间差异和协变量效应．Ｓｔｅ－ｐｗｉｓｅ方法的多重回归分析表明,生态环境艰难程度、生产方式所决定的食物贮存程度、社会结构的紧密性、社会化的倾向性和现代化影响是预测被试认知操作和认知方式的有效因素．研究结果与“中国人认知操作和认知方式与生态文化关系”的理论模式所提出的预测基本一致,即研究结果支持了该理论模式．     

外资企业员工群体间应激的比较

本研究采用测量和问卷调查的方法考察了广东外资企业中的三类员工 (即内地员工、港澳员工和本地员工 )共 2 2 7名被试和内地国营企业员工共96名被试的应激及其相关因素。被试应激水平的组间比较表明 :外资企业员工的应激水平均显著高于国营企业员工 ;外资企业各类员工之间在应激水平上均存在显著差异 ;外资企业员工的进厂时间与被试的应激水平呈倒 U型曲线关系 ,而员工的学业与应激水平呈 U型曲线关系。回归分析表明 :外资企业中各类员工的应激有共同的相关因素 ,也有各自特殊的相关因素。     

意志与意识对记忆的交互影响

运用加工分离程序,研究了编码和提取时不同意志和意识水平对部首补笔的影响。结果发现：除编码阶段和提取阶段的意志之间不存在交互作用之外,同一阶段和（或）不同阶段的意志和（或）意识之间均存在显著的或非常显著的交互作用。研究表明：意志和意识两个因素对记忆存在复杂影响,在记忆研究中应关注意志因素的作用。研究结果验证了记忆的状态依存性。     

A cellular analogue of operant conditioning.

Using the hippocampal-slice preparation, we attempted to model operant conditioning in vitro by reinforcing pyramidal cell bursting responses with local micropressure applications of transmitters and drugs. The same injections were administered independently of bursting to provide a "noncontingent" control for direct pharmacological stimulation or facilitation of firing. The results suggested that the bursting responses of individual CA1 pyramidal neurons may be reinforced in a dose-related manner by response-contingent (but not noncontingent) injections of dopamine and the selective dopamine D2 agonist, N-0923. N-0924, a stereoisomer of N-0923 that is largely devoid of D2-agonist activity, failed to reinforce CA1 bursting. Burst-contingent injections of the excitatory neurotransmitter glutamate also failed to reinforce CA1 bursting; indeed, the glutamate applications (whether contingent or random) reduced the likelihood of bursts while increasing the frequency of solitary spikes. Reinforcement delays exceeding 200 ms largely eliminated the reinforcing efficacy of the D2 agonist N-0437 in CA1 operant conditioning. The results are consistent with the suggestion that the behaviorally reinforcing effects of dopaminergic agents can be modeled in vitro in the hippocampal-slice preparation.     

加压素对记忆巩固过程作用的研究 Ⅰ.精氨酸加压素(AVP)对大鼠记忆巩固过程的易化作用及脑内游离氨基酸含量的变化

本文研究了精氨酸加压素易化记忆巩固过程的作用,测定了这一作用过程中脑内15种游离氨基酸含量的变化。 1.第三天建立实验前1小时皮下注射AVP(2μg/只)显著地延缓了大鼠主动逃避条件反应的消退过程。 2.给予AVP的动物在建立期皮层视区和海马两脑区的GABA(γ-氨基丁酸)含量及海马的异亮氨酸含量下降。在保持期两脑区的苏氨酸含量下降,赖氨酸含量上升,海马的谷氨酸含量下降,但两脑区的GABA含量都没有显著变化。 3.电击应激反应的实验结果表明,给予AVP的动物海马的GABA含量及皮层视区苯丙氨酸含量下降。单独注射AVP后1小时,两脑区的天冬氨酸含量下降。AVP注射后48小时,脑内各种氨基酸含量都没有明显变化。     

Lebenswelt structures of Galilean physics: The case of Galileo's pendulum

The aim of this paper is to give a self-reflective account of the building of Galileo's pendulum in order to discover what were the practical contingencies of building and using the pendulum for demonstrating the law of isochronism. In doing this, the unique Lebenswelt structures of Galilean physics are explicated through the ethnomethodological concepts developed by Harold Garfinkel. The presupposition is that the practical logic of Galilean physics is embedded in the instruments themselves. In building the pendulum and recovering its original use, Galilean physics becomes for ethnomethodologists a first-hand practical discovery. This is not a reconstruction of the mind of the historical Galileo but, rather, an explication of Galileo's practical perspective on the instrument as an intersubjective and interchangeable standpoint available for ethnomethodological analysis. This enables us to study historical facts from the standpoint of the practical logic of the original practice with a pedagogical eye for the instructive reproducibility of science.I would like to thank Mike Lynch, Eric Livingston, Jim MacLachlan, and Shelley Schweizer-Bjelic for their comments     

成熟对青春期型反社会行为的影响

Moffitt的反社会行为发展理论将反社会行为分为两种类型, 即终身型和青春期型, 其中, 青春期型反社会行为在青少年群体中发生的频率更高, 它一般在青春期早期产生, 在青春期晚期或成年期早期结束, 青春期个体的发育成熟会对青春期型反社会行为产生影响。成熟包括生理成熟和心理成熟两方面, 生理成熟或心理成熟的单独影响和共同影响均从不同角度解释了青春期型反社会行为的产生、发展和停止：生理成熟对青春期型反社会行为具有发展和强化作用; 心理成熟对青春期型反社会行为具有减缓和削弱作用; 生理成熟与心理成熟的交互作用减弱或强化了青春期型反社会行为; 生理成熟与心理成熟之间的成熟差距抑制了青春期型反社会行为。未来的研究还需就拓展不同类型成熟的研究、改进成熟度的计算方法、结合青少年成熟特点进行有针对性干预等方面进行更多的尝试和探索。

Measurement bias and error correction in a two-stage estimation for multilevel IRT models

Among current state-of-the-art estimation methods for multilevel IRT models, the two-stage divide-and-conquer strategy has practical advantages, such as clearer definition of factors, convenience for secondary data analysis, convenience for model calibration and fit evaluation, and avoidance of improper solutions. However, various studies have shown that, under the two-stage framework, ignoring measurement error in the dependent variable in stage II leads to incorrect statistical inferences. To this end, we proposed a novel method to correct both measurement bias and measurement error of latent trait estimates from stage I in the stage II estimation. In this paper, the HO-IRT model is considered as the measurement model, and a linear mixed effects model on overall (i.e., higher-order) abilities is considered as the structural model. The performance of the proposed correction method is illustrated and compared via a simulation study and a real data example using the National Educational Longitudinal Survey data (NELS 88). Results indicate that structural parameters can be recovered better after correcting measurement biases and errors.
