Procedure and reliability of conditioned respiratory suppression

Changes in respiration amplitude, respiration rate, and heart rate in response to a conditioned signal for shock were measured concurrently in kittens and adult cats. The data were analyzed with respect to qualitative and quantitative variability across trials and subjects; correlation among measures; skewness; and kurtosis. Suppression of respiration amplitude was the most reliable response across trials and subjects, with increases in respiration rate second and heart rate by far the least reliable. Correlations between each pair of measures were moderate. Respiration-amplitude responses were negatively skewed, but this deviation from normality was moderate and consistent across subjects. The measurement of conditioned respiratory suppression is a viable addition or alternative to the conditioned emotional response procedure in studies of classically conditioned fear.     

替考枪手的故事

尽管Brightly和Leitner这两个名字给人以光明闪耀的印象，但这里要讲的却是黑暗的故事。WaYne Brightly是纽约市以作曲家John Philio Sousa名字命名的中学的社会学教师，他成绩不良的记录十分惹眼，包括多次未通过教师资格认证考试。Rubin Leitner曾经是流浪汉，据报道还患有Asperger综合症，这是一种发育障碍，其特征是“过分专注于某些事物，人际关系差，存在沟通障碍”——根据本人2003年10月的《反重力思考》专栏中的介绍。     

复杂系统视角下的组织学习动态过程研究

组织是一个具有无尺度网络结构的复杂系统。组织学习作为组织获取核心竞争力和可持续发展能力的重要手段,是一个动态的过程:从组织学习发生的载体来看,主要有个人、团队和组织等三个层次;就组织学习发生的方式来看,包括单环学习、双环学习和三环学习等三种模式;而从组织学习过程本身来看,则分为直觉感知、解释说明、归纳整合和制度化等四个子过程。本文在系统回顾相关研究成果的基础上,从复杂系统的角度对组织学习过程进行了系统的模型整合和创新,对复杂系统环境下如何构建学习型组织的可能遇到的障碍进行了一系列的分析。     

Writing expository essays from social studies texts: a self-regulated strategy development study

Skills‐Based Training and Counseling Self‐Efficacy

The authors studied the effectiveness of the skilled counselor training model (SCTM). Counseling students who completed the SCTM demonstrated greater gains in skills acquisition and counseling self‐efficacy than counseling students who did not receive the training. At pretest, the counseling students in both groups, doing self‐appraisals, rated their performance of counseling skills significantly higher than trained raters assessed the students' performance of counseling skills. At posttest, members of the control group continued to overestimate their skills levels when compared with the ratings given by the trained raters, whereas, in comparison, students who received SCTM training underestimated their performance.     

Sharing Stories: Parents' Involvement in Reading with Inner-City Nursery Children

Recent research has underlined both the benefits of parents reading stories to their children before they start school and of parental involvement in the early reading stages. A one-year project was carried out in the nursery class of an inner-city primary school to set up a regular book borrowing service to enable and encourage parents to read regularly to their pre-reception class children. The level of parental and child interest was monitored throughout. An attempt to measure the effect of the input was made by testing the children involved in the project at the end of their reception class year. Although the results do not show any significant difference in the level of achievement between the experimental school and the two control schools, the project did reveal an unexpectedly high level of parental interest in orienting children towards literacy.     

Social Foundations of Education as an Unwelcome Counter-Narrative and as Educational Praxis

I am grateful for this opportunity to reflect on the field of Social Foundations of Education (SFE), in part because it affords an opportunity to advance an historical analysis of the trajectory of the field different from what we provided when my colleagues and I sent to press the Handbook of Research the Social Foundations of Education in 2009 (Tozer, Gallegos, Henry, 2011 Tozer, S. E., & Butts, R. F. (2011). The evolution of social foundations of education. In Tozer, S., Gallegos, B., & Henry, A., (Eds), Handbook of research in the social foundations of education (pp. 1–14). New York: Routledge. [Google Scholar]). I also welcome the opportunity to acknowledge a particular activist tradition established by earlier generations of Social Foundations scholars who have influenced my work. To quote Stuart Hall, these men and women engaged Social Foundations “as a practice which always thinks about its intervention in a world in which it would make some difference, in which it would have some effect” (in Tozer et?al., 2011 Tozer, S., Gallegos, B., & Henry, A. (2011). (Eds.). Handbook of research in the social foundations of education (p. 11). New York, NY: Routledge. [Google Scholar], p. 11). Finally, this occasion invites a perspective on the equity work in Chicago Public Schools that we have pursued since I introduced it in my AESA Presidential Address in 2006.
