培养高职生责任意识的思考

人在社会实践中,无论是否意识到,每个人都要对自己、他人、集体和社会承担一定的责任,这种责任就形成了我们促进自身发展和社会进步的驱动力。从社会实质上看,责任意识反映的是人的价值问题即社会对个人的尊重和满足,以及个人对社会的职责和贡献,对任何个人来说都是不可推卸的,是一种自我约束的价值取向。近年来,高等职业院校培养了大批优秀技能型人才,但从德育上看,高等职业教育仍有其薄弱环节,尤其是高职学生责任意识培养方面还存在一些问题,导致部分高职学生缺乏责任意识。     

《诗经》无长篇史诗原因探究

由《诗经》中有无史诗引出为何无长篇史诗的关键问题,《诗经》没有长篇史诗的原因较复杂,影响它的因素很多,特别是周人单一神教、人神分离的宗教思想,具有明确政治目的的采诗制度以及q-国诗歌重抒情、言简意赅的特点影响了长篇史诗的形成。     

Feminist philosophy of science: ‘standpoint’ and knowledge

Feminist philosophy of science has been criticized on several counts. On the one hand, it is claimed that it results in relativism of the worst sort since the political commitment to feminism is prima facie incompatible with scientific objectivity. On the other hand, when critics acknowledge that there may be some value in work that feminists have done, they comment that there is nothing particularly feminist about their accounts. I argue that both criticisms can be addressed through a better understanding of the current work in feminist epistemology. I offer an examination of standpoint theory as an illustration. Harding and Wylie have suggested ways in which the objectivity question can be addressed. These two accounts together with a third approach, ‘model-based objectivity’, indicate there is a clear sense in which we can understand how a standpoint theory both contributes to a better understanding of scientific knowledge and can provide a feminist epistemology.

The role of scaling up research in designing for and evaluating robustness

One of the great strengths of Jim Kaput’s research program was his relentless drive towards scaling up his innovative approach to teaching the mathematics of change and variation. The SimCalc mission, “democratizing access to the mathematics of change,” was enacted by deliberate efforts to reach an increasing number of teachers and students each year. Further, Kaput asked: What can we learn from research at the next level of scale (e.g., beyond a few classrooms at a time) that we cannot learn from other sources? In this article, we develop an argument that scaling up research can contribute important new knowledge by focusing researchers’ attention on the robustness of an innovation when used by varied students, teachers, classrooms, schools, and regions. The concept of robustness requires additional discipline both in the design process and in the conduct of valid research. By examining a progression of three studies in the Scaling Up SimCalc program, we articulate how scaling up research can contribute to designing for and evaluating robustness.

秦汉时期人的社会文化素质探析

随着秦汉大一统局面的形成,后来影响中国千百年的经济、政治、文化制度及政策得以建立并逐步完善。另外,大一统局面的形成,促进了民族融合,为汉民族的形成创造了有利条件。秦汉时期文化教育发达,科学技术进步,人的活动区域扩大,实践能力提高,民主意识萌芽,以"孝"为代表的道德素质成为人的素质的鲜明特点,人的社会文化素质呈现上升态势。

准确测定含金废液中金含量的影响因素控制

镀金溶液中当金的含量降低到一定量以后,都将报废成为镀金废液。从废液中回收黄金的问题,不仅具有很高的经济价值更重要的是消除或减轻废液对环境的污染。因此,如何快速定量测出金的含量将为废液金的回收提供必要的数据参数。通过实验,筛选优化了NH4HF^2-碘量法准确测定金含量的最佳试验条件。对稳定剂HCl浓度、镀金液的消解条件、残余硝酸及Pb^2＋、Cu^2＋、Fe^2＋、Co^2＋、Sb^3＋等重金属离子,对测定结果的影响作了对比;试验表明该方法直接测定微量金的下限为6mg／L。为废液中金的准确测定提供实验依据。     

从变质量物体的运动谈起

牛顿运动定律以及由牛顿第二定律推导出的动量定理、动量矩定理、动能定理,只适用于宏观低速的情况下,而且在运动的过程中,物体的质量是恒定不变的。然而在宏观低速的情况下,我们会遇到许多变质量物体运动的问题,在此情况下,牛顿运动定律以及由此推导出的三条基本定理将要做一定的修改,其表达式是不一样的。     

中国古代文人画线条特征简析

中国传统绘画以线条为主要造型手段,文人画最充分地展示了笔墨情趣和线条美。本文认为,文人画的线条美表现在三个方面：神采飞扬、删繁就简和以书入画。文人画巩固了对线条美的追求,强化了中国画意象造型的传统,并促成了人们审美观念和审美趣味转向笔墨形式。
