Unsustainable Growth,Hyper-Competition,and Worth in Life Science Research: Narrowing Evaluative Repertoires in Doctoral and Postdoctoral Scientists’ Work and Lives

There is a crisis of valuation practices in the current academic life sciences, triggered by unsustainable growth and “hyper-competition.” Quantitative metrics in evaluating researchers are seen as replacing deeper considerations of the quality and novelty of work, as well as substantive care for the societal implications of research. Junior researchers are frequently mentioned as those most strongly affected by these dynamics. However, their own perceptions of these issues are much less frequently considered. This paper aims at contributing to a better understanding of the interplay between how research is valued and how young researchers learn to live, work and produce knowledge within academia. We thus analyze how PhD students and postdocs in the Austrian life sciences ascribe worth to people, objects and practices as they talk about their own present and future lives in research. We draw on literature from the field of valuation studies and its interest in how actors refer to different forms of valuation to account for their actions. We explore how young researchers are socialized into different valuation practices in different stages of their growing into science. Introducing the concept of “regimes of valuation” we show that PhD students relate to a wider evaluative repertoire while postdocs base their decisions on one dominant regime of valuing research. In conclusion, we discuss the implications of these findings for the epistemic and social development of the life sciences, and for other scientific fields.     

论蔡元培"教授治校"的民主管理思想

蔡元培先生在北京大学开创了我国"教授治校"的先河,其实质是通过分权来保障学术自由和大学自治.文章在分析"教授治校"民主管理思想的产生与实践的基础上,阐释了"教授治校"的内涵,提出了对现代大学内部进行管理体制改革的构想:进一步明确划分了管理的权限;改革治理机构;现实管理主体的多元化;坚持以人为本,通过人本管理来唤醒管理者的主体意识.     

A learning-based method to detect and segment text from scene images

This paper proposes a learning-based method for text detection and text segmentation in natural scene images. First, the input image is decomposed into multiple connected-components (CCs) by Niblack clustering algorithm. Then all the CCs including text CCs and non-text CCs are verified on their text features by a 2-stage classification module, where most non-text CCs are discarded by an attentional cascade classifier and remaining CCs are further verified by an SVM. All the accepted CCs are output to result in text only binary image. Experiments with many images in different scenes showed satisfactory performance of our proposed method.

如何提高学生学习信息技术课的兴趣

中小学生信息技术教育是我国教育信息化建设的重要组成部分.在当前,基于信息技术教育方面的课程整合、校园网、校校通、网络教育资源库,以及基于网络的研究性学习等焦点、热点问题层出不穷,此可谓"热".然而,"学生喜欢玩电脑,但最不喜欢上信息技术教育课"却几乎成了普通现象,此又可谓"冷".看来,要将社会的期望转化为学生的心愿,要真正使学生学好这门课程,去适应社会日益信息化的趋势,还需要从提高学生学习信息技术教育课的兴趣入手.
