对课程导师制在远程开放教育中运用的探讨

远程开放教育以全新的结构与视角冲击着传统的校园围墙教育。在这个冲击波中教师的角色定位有了全新的内涵。本文从开放教育课程导师制的定义、内容、作用和构建的必要性对建立课程导师制的可行性进行了探讨。     

价值论维度的科学精神和人文精神的统一

人类的实践活动只有做到既遵循真理原则,又遵循价值原则,才能保证实践的成功。正是基于实践的这一要求,人们逐渐形成了科学精神和人文精神,并形成了以二者统一作为实践的指导思想和行为规范的原则。从这个意义上讲,价值论是科学精神和人文精神统一的重要理论基础,离开价值论谈科学精神与人文精神的统一是片面的和不现实的。

Yangxueqingnao particles inhibit rat vascular smooth muscle cell proliferation induced by lysophosphatidic acid

Objective: To observe the effect of Yangxueqingnao particles on rat vascular smooth muscle cell (VSMC) proliferation induced by lysophosphatidic acid (LPA). Methods: The amount of3H-TdR (3H-thymidine) admixed in cultured rat VSMC was measured and mitogen-activated protein kinase (MAPK) activity and lipid peroxidation end product malondialdehyde (MDA)content of the VSMC were assayed. Results: 1×10-9, 1×10-8, 1×10-7 mol/L LPA in a concentration dependent manner, induced the amount of 3H-TdR admixed, MAP kinase activity, and MDA content of the cultured rat VSMC to increase. However, 5%, 10%,and 15% Yangxueqingnao serum preincubation resulted in a decrease of 23.0%, 42.0%, and 52.0% (P＜0.01) respectively in the amount of 3H-TdR admixed, a decline in VSMC MAP kinase activity of 13.9% (P＜0.05), 29.6% (P＜0.01), and 48.9% (P＜0.01)respectively, and also, a decrease in MDA content of VSMC of 19.4%, 24.7%, and 43.2% (P＜0.01) respectively, in the 1×10-7mol/L LPA-treated VSMC. Conclusions: LPA activates the proliferation and lipid peroxidation of VSMC in a concentration dependent manner. The LPA-induced VSMC proliferation is related to the activity of MAP kinases, enzymes involved in an intracellular signalling pathway. The results of the present study showed that Yangxueqingnao particles can effectively inhibit LPA-induced VSMC proliferation, MAP kinase activation, and reduce lipid peroxidative lesion.     

近10年国内工业旅游研究回顾与展望

工业旅游是近年来旅游研究的一个热点领域。运用比较分析法,从概念特征、旅游资源、旅游产品、客源市场等8个方面对近10年来工业旅游的研究内容进行了梳理,初步分析了国内工业旅游的研究方法。依据现有的研究文献,完整的理论体系还未构建起来,定性研究是我国工业旅游研究的主导范式。今后的研究主要可以从理论体系、研究领域、研究方法、产品设计、学术交流等5个方面加以深入。

How do people read the passages during a reading comprehension test? The effect of reading purpose on text processing behavior

In this study, we investigate the effect of reading purpose on students’ processing behavior during a reading comprehension test. In a repeated measures design, sixty undergraduates answered multiple-choice (MC) reading comprehension questions in a condition with no overarching goal for reading and in an alternate condition where the same students were first provided with the goal of summarizing the text before answering MC questions. Results from eye tracking analysis showed that when students read and answered questions without an overarching goal, they spent much less time reading the passages before answering the questions, more time re-reading the texts while answering the questions, and more time on parts of the text that were not necessary to answer the questions. We conclude that providing examinees without an explicit goal for reading may inadvertently encourage a “search for the answer” reading process, rather than on building a coherent mental model of text content.     

悲情政治的艺术解读--毛泽东诗词的悲剧精神

悲情政治是政治的基本形态和最高追求。悲情政治以对立为基本元素，以生存价值为动力，以独立意志为基石，以乐观主义为本质要求。毛泽东极具悲剧精神的诗词创作，艺术地再现了悲情政治的基本特征。

试论《商君书》关于选任官吏的思想

《商君书》蕴含有丰富的选官思想，对于官吏的起源、地位、作用、选拔和任用以及对官吏的控制、精简等等都有阐述。它在秦国历史上产生过重要的影响，起到了积极的、进步的历史作用，在深化人事体制改革的今天，为了记取历史的经验和教训，我们仍有必要对此进行研究和总结。
