The Rhetoric of War and Remembrance: An Analysis of President Bill Clinton's 1994 D-Day Discourses

This close textual analysis of President Clinton's discourses in ceremonies commemorating the fiftieth anniversary of D-Day, held on June 6, 1994, considers the rhetorical context and discursive strategies of the president on an international stage. It argues that Clinton employed generational comparisons to emphasize the gifts bequeathed by an older generation and the obligation to advance the goals of democracy in a new era. The four speeches analyzed provide evidence of the force of prudential reasoning in commemorative situations.     

跑台运动通过p38信号上调FNDC5激活Akt改善Ⅱ型糖尿病小鼠认知功能障碍

目的:探讨8周跑台运动对db/dbT2DM小鼠认知功能的影响及其分子机制。方法:24只8周龄db/dbT2DM小鼠和8只同龄对照m/m小鼠,将db/db小鼠随机分为:模型组(db/db)、运动干预组(db+Exe)、运动联合p38抑制剂组(db+Exe+SB203580)。db+Exe组进行8周跑台训练,db+Exe+SB203580组进行8周跑台运动联合SB203580抑制剂灌胃处理(5mg/kg,3d/W,8W)。每周定时检测小鼠的体重和空腹血糖;干预结束后,取全脑及海马组织,免疫组织化学染色观察海马不同区域的神经元损伤状态;Western Blot检测海马组织中AD样病理、神经炎症、突触可塑性、过氧化物酶体增殖物激活受体γ辅激活因子1α(PGC-1α)/Ⅲ型纤连蛋白组件包含蛋白5(FNDC5)、Akt激酶等蛋白的表达。结果显示:(1)跑台运动可明显改善db/db小鼠的认知功能障碍。(2)减轻db/db小鼠的海马神经元损伤。(3)降低海马内AD样病理、神经炎症蛋白的表达,增加突触蛋白的表达水平。(4)通过p38信号上调PGC-1α/FNDC5的表达。(5)跑台运动可激活Akt激酶,而p38抑制剂可降低跑台运动对Akt激酶的激活作用。结论:8周跑台运动可明显改善db/db小鼠的认知功能障碍,其机制可能是通过p38上调PGC-1α/FNDC5,激活Akt激酶,减弱AD病理进程,降低炎性反应,增加突触可塑性,改善其空间学习记忆能力。     

An Experimental Study of the Effect of Educational Guidance on a Selected Group of High School Sophomores

The question of an interaction over time between ability grouping and personality variables was the focus of the present study which examined pertinent data from 260 female high school students. Two standardized personality instruments, in addition to several scales designed by the E’s, were administered to students of the upper and lower ability tracks in a Catholic high school, grades 9 and 12. Ss in the lower track were found to have a lower need for achievement, a higher need to avoid failure, and a higher average score of test anxiety than Ss in the upper track. The effects of ability grouping did interact with grade level for a correlate of personality, level of aspiration. Relative to Ss in the upper track, the lower track Ss experienced a reduction in level of aspiration over time. Both future directions of associated research and educational practices were discussed within the context of the present findings.     

Defining and Applying Idea Technologies

Abstract

In this paper we define and explain idea technologies, illustrate how they operate in learning environments, then present and explore the pedagogical advantages of using our three-tiered, idea-technology classification system. We believe it will serve as an introductory primer, or conceptual framework, for university professors, educational technologists, teacher educators, and university administrators. Like any sound grammar, we believe our conceptual framework not only provides structure, economy, and flexibility, but also possesses the added benefit of never “crashing” as it improves teaching and learning.     

WebCT and Its Growth as a Type II Application

Abstract

Maddux, Johnson, and Willis mentioned in 1992 some “yet-to-be-developed types” that “have the potential to be Type II software if they are used in such a way that the user is given the ability to learn in new and better ways.” The authors of this paper will frame the discussion of learning management systems (LMS) around the concept of Type I and Type II applications of computers in education. We suggest that with the new trends of interoperability within WebCT, more researchers will accept WebCT as a potential Type II application. As more interactive learning objects are developed and shared on the WebCT format, it should be easier for instructors to create and teach courses that reflect the value systems expressed in the concept of Type II learning.     

太极拳对中老年人血脂及肥胖II型糖尿病的调节作用

目前全世界不管是发达国家、发展中国家还是落后的国家中,都有相当一部分中老年人是高血脂、肥胖II型糖尿病人。为探索太极拳运动对这些人健身防病的作用,检测长期坚持太极拳运动对中老年人锻炼与非锻炼的血脂,脂蛋白代谢及肥胖II型糖尿病患者各项指标的变化情况,结果显示经常坚持太极拳运动可降低血脂,调节脂类代谢,特别对改善肥胖II型糖尿病患者代谢紊乱起到重要作用。

The Joint Establishment of the World Federation of Scientific Workers and of UNESCO After World War II

The World Federation of Scientific Workers (WFScW) and UNESCO share roots in the Social Relations of Science (SRS) movements and in the Franco-British scientific relations which developed in the 1930s. In this historical context (the Great Depression, the rise of Fascism and the Nazi use of science, the social and intellectual fascination for the USSR), a new model of scientific internationalism emerged, where science and politics mixed. Many progressive scientists were involved in the war efforts against Nazism, and tried to prolong their international commitments into peacetime. They contributed to the establishment of the WFScW and of UNESCO in 1945–1946. Neither the WFScW nor UNESCO succeeded in achieving their initial aims. Another world emerged from the immediate post-war years, but it was not the world fancied by the progressive scientists from the mould of scientific internationalism. The aim of this article is to follow the path from the Franco-British networks towards the establishment of the WFScW and UNESCO; from an ideological scientific internationalism towards practical projects. It is to understand how these two bodies came to embody two different scientific internationalisms during the Cold War.
