恩格斯《自然辩证法》科学方法论及其当代意蕴

恩格斯《自然辩证法》是一部马克思主义经典著作,以辩证唯物主义认识论为指导,对自然科学发展情况进行了全面考查,系统地论述了科学方法论,总结了科学方法论的理论特征,对科学方法论的运用、创立和发展作出了重大贡献。今天我们学习和研究自然辩证法,掌握科学方法论,对于推动社会进步、促进科技发展、贯彻新的发展理念和提高科学素养具有重要意义。     

Mechanisms,the interventionist theory,and the ability to use causal relationships

In the area of social science, in particular, although we have developed methods for reliably discovering the existence of causal relationships, we are not very good at using these to design effective social policy. Cartwright argues that in order to improve our ability to use causal relationships, it is essential to develop a theory of causation that makes explicit the connections between the nature of causation, our best methods for discovering causal relationships, and the uses to which these are put. I argue that Woodward's interventionist theory of causation is uniquely suited to meet Cartwright's challenge. More specifically, interventionist mechanisms can provide the bridge from ‘hunting causes’ to ‘using them’, if interventionists (i) tell us more about the nature of these mechanisms, and (ii) endorse the claim that it is these mechanisms—or whatever constitutes them—that make causal claims true. I illustrate how having an understanding of interventionist mechanisms can allow us to put causal knowledge to use via a detailed example from organic chemistry.

高师化学实验绿色化问题的研究

化学实验教学中使用的药品种类繁多、性能复杂,常常给环境带来负面作用.已经查明现行高师化学教学实验存在一系列的环境污染问题,对此遵循绿色化学的提出12项基本原则分别对环境友好实验材料的使用、防止有毒物质的泄露等问题等进行了研究和实践,通过化学实验课程绿色化问题的研究性学习取得了绿色化学实验和绿色化学教育的双赢.     

无机化学实验教学中过程与方法目标的实施

实验是化学、生物等理科学科的重要组成部分,实验教学是提高学生科学素养与综合能力的最佳途径。本文介绍了在无机化学实验教学中实施过程与方法目标的分解与细化,使相对粗放的实验教学转化为量化教学的改革探讨。     

论邓小平社会主义本质论的理论创新

邓小平的社会主义本质论是中国特色社会主义理论的一项重大的理论创新。其真实理论意蕴和理论创新在于：在坚持社会主义制度的前提下追问社会主义社会的二级本质,用唯物史观的哲学原理深刻地揭示了社会主义制度的功能性本质,在更深层次上回答了＂什么是社会主义,怎样建设社会主义＂这一根本问题,把对社会主义的认识提高到新的科学水平,构筑了当代社会主义理论的重要基石。     

萘及其1-卤素取代化合物的荧光光谱的量子化学研究

萘及其化合物一般具有较大的共轭体系,是一类良好的电致发光材料.对萘及其卤代化合物的荧光光谱进行了理论研究.在B3LYP/6-31G水平下优化了4种化合物的几何构型.在振动分析中,均未出现虚频率.基于此,在B3LYP/6-31G的水平下计算了该类化合物的荧光光谱,所有计算结果与实验值基本吻合.     

Synthesis of a novel multi-SO3H functionalized strong Brønsted acidic ionic liquid and its catalytic activities for acetalization

The novel multi-SO3H functionalized strong Bronsted acidic ionic liquid has been prepared and its catalytic activities were investigated through the acetalization. The results showed that the novel catalyst was very efficient for the reaction with the average yield over 90% under solvent-free condition at room temperature. Operational simplicity, without need of any solvent, a small amount of usage, low cost of the catalyst used, high yields, applicability to large-scale reactions and reusability are the key features of this methodology. The novel catalyst also has great potential for the green process.
