Ethical control of innovation in a globalized and liberal world: Is good science still science?

The independence of science was long seen as of prime importance. This position has become less common today. The perception of scientific research as a public service has led to the opinion that it must be accountable to citizens and produce knowledge and innovation that meet their expectations. Numerous authors have voiced the need for anticipatory ethical control of innovation focusing on the scientific research process. This control is considered as the must-have guarantee for “good science.” The current article attempts to trace the ideological origins of the ethical control of innovation, examines its effectiveness against the challenge of globalization and technology-derived major threats and its compatibility with scientific methodology. It also suggests ways to both regulate the innovation process and preserve the independence of science. On the whole, we conclude that truly effective ethical regulation of innovation, i.e. one that protects the greatest number from its adverse effects, is achieved first and foremost by questioning our liberal economic model and the place given to science in our societies.

近50年秋季全球旱涝年的分布特征及其与海温和ENSO的关系

该文用Chen等(2001)最新创建的全球陆地月降水资料(PREC/L),划分并检验了1948年～2001年全球9月～11月的旱涝年.结果表明,冷事件大多对应涝年,暖事件大多对应旱年.全球9月～11月降水有明显的年代际变化,涝年大多在80年代以前,早年大多从80年代开始.其中,1987年～1997年全球9月～11月的连续早年,是一个非常特殊的时段.指出,印度季风区域、东南亚地区、热带太平洋岛屿、我国的东南沿海及日本一带、西非季风区及墨西哥湾区域,是旱涝年的平均降水差异较大的区域.并指出,东太平洋和西南太平洋3月～5月海温的变化对于9月～11月全球陆地降水的趋势变化有很好的预报意义.划分并检验了南、北半球9月～11月的旱涝年.指出,北半球旱涝年的分布和全球的是基本一致的,南半球与北半球的旱涝年的分布具有明显的正相关.     

Understanding student evaluations of teaching in online learning

In this paper, we have developed a classification model for online learning environments that relates the Instructors Overall Performance (IOP) rating (according to students’ perceptions) with the course characteristics, students’ demographics and the effectiveness of the instructor in his/her teaching roles. To that end, a comprehensive Student Evaluation of Teaching (SET) instrument is proposed, which includes not only conventional teaching elements, but also items that encourage twenty-first century skills. The goal of the study is twofold: (i) to quantify the extent to which the selected variables explain the IOP rating, and (ii) determine which teaching and non-teaching variables most affect the IOP rating. The best performing classifier achieved a competitive accuracy, highlighting that the selected variables mainly determine the IOP values. Other important findings include: (i) the IOP value is mainly influenced by the effectiveness of the instructor in his/her teaching roles; (ii) teaching strategies that involve the cooperation between the technical and pedagogical roles should be promoted; (iii) the pedagogical role has the highest impact on the final IOP value; and (iv) the most influential demographic variable is the student’s status (working commitments and family responsibilities).

论社会资本的运作空间

在竞争空前激烈、信息爆炸的现代社会，社会资本的运作空间非常之大，因而使作为一种事实存在的社会资本运作空间被学术界所忽视，但作为一种理论工具的社会资本运作空间的存在是不能被忽视的，因为它是一个非常有解释能力的概念工具，本文在对社会资本的本质特征分析的基础上，提出了社会资本运作空间这一概念，并针对社会资本功能发挥和工具性使用的特点，构建了社会资本运作的空间模型，最后，文章运用社会资本的运作空间这一理论工具分析了当前中国社会的就业机制。     

A family of quasi-cubic blended splines and applications

INTRODUCTION Bézier curves and uniform B-spline curves are powerful tools for constructing free form curves and surfaces (FFC/FFS). But they cannot represent the arcs, hyperbola, sphere, cylinders and other transcendental curves and surfaces exactly. In order to avoid the in- conveniences, many bases are presented in other new spaces (Zhang, 1996; Pe?a, 1997; Walz, 1997; Sánchez-Reyes, 1998; Mainar et al., 2001). Note that, these existing methods can deal with both polynomial curve…
