Organizational Climate: Its Appearance and Hierarchical Relationship——A Perspective from the Body-Emotion Theory of Hermann Schmitz’s New Phenomenology

摘要 谈起组织氛围，每个人都不会陌生，人们在不同的环境中会体验到不同的氛围，从这个角度看，组织氛围有其客观存在性；然而组织氛围往往要通过组织成员的主观感受表达出来，从这个角度看，组织氛围又有其主观内在性。通过以往的研究文献回顾，我们发现：经过将近八十年的关于组织氛围的研究，学界依然没有就组织氛围是什么，如何形成等方面达成一致。在以往的研究过程里始终没有把组织氛围的客观存在性和主观感受性很好地统一起来。主流认知学派多将组织氛围当作是组织成员对客观环境的认知结果，但是没有进一步发现组织中的统一的认知、情感和行为是如何形成的。 本文将以德国现象学家施密茨的身体情感现象学视角来解读组织氛围的形...Abstract Study of organizational climate has a very long history in management, but what is organizational climate and how it forms remains unknown. As the researches in this field are restricted to traditional cognition psychology. The phenomenon of organizational climate features with dual attributes, namely internal subjectivity and external objectivity, and therefore can’t be thoroughly revea...学位：管理学硕士院系专业：管理学院_企业管理学号：1762013115129

Detection of incoherent broadband terahertz light using antenna-coupled high-electron-mobility field-effect transistors

The sensitivity of direct terahertz detectors based on self-mixing of terahertz electromagnetic wave in field-effect transistors is being improved with noise-equivalent power close to that of Schottky-barrier-diode detectors. Here we report such detectors based on AlGaN/GaN two-dimensional electron gas at 77~K are able to sense broadband and incoherent terahertz radiation. The measured photocurrent as a function of the gate voltage agrees well with the self-mixing model and the spectral response is mainly determined by the antenna. A Fourier-transform spectrometer equipped with detectors designed for 340, 650 and 900~GHz bands allows for terahertz spectroscopy in a frequency range from 0.1 to 2.0~THz. The 900~GHz detector at 77~K offers an optical sensitivity about $1~\mathrm{pW/\sqrt{Hz}}$ being comparable to a commercial silicon bolometer at 4.2~K. By further improving the sensitivity, room-temperature detectors would find applications in active/passive terahertz imaging and terahertz spectroscopy.Comment: 4.5 pages, 5 figure

Design of Teaching Activities in Universities based on Network Platform and Information Technology

随着计算机、手机和平板电脑的迅速发展,网络平台的运用和涉及的范围越来越广泛,信息技术应用于现代教学中是-种必然的趋势.文章讨论网络平台和信息技术在现代教学中的运用,以“慕课”和课堂教学混合模式为例,展开讨论网络平台和信息技术在国内高校课堂教育中发挥的作用,对比慕课在线课程和传统课堂优劣,探究如何有效运用慕课在线学习平台和信息技术进行教学活动设计,开展混合教学,提高课堂教学质量.With the rapid development of computer, mobile phone and tablet PCs, the use and the cov-erage scope of network platform are becoming more and more widely. It becomes an inevitable trend to apply the computer information technology into the modem teaching. This paper discusses the application of network platform and information technology in teaching and takes the blended mode of MOOC （Massive Open Online Course） and traditional teaching as an example to discuss the role of the network platform and information technology played in the classroom education of domestic universities. Comparing the advantages and disadvan-tages of MOOC online courses and traditional classroom teaching, we explore how to use the MOOC online learning platform and information technology effectively to design teaching activities and carry out blended teaching to improve the quality of classroom teaching.厦门大学示范性网络课程建设项目“生物化工、微生物学实验、食品安全与健康饮食、出国留学指导”

Direct secretory expression of active microbial transglutaminase in Pichia pastoris

使用异源表达系统直接分泌表达具有活性的微生物谷氨酰胺转氨酶(MICrObIAl TrAnSgluTAMInASE,MTg)是目前最具前景的MTg生产方法之一,但由于产量较低无法实现工业化生产。毕赤酵母是近年来发展出的高效蛋白表达系统。通过采用PrO序列与成熟MTg基因共表达的策略,成功地实现了用重组毕赤酵母分泌表达具有活性的茂原链霉菌STrEPTOMyCES MObArAEnSE MTg。进一步通过对PrO序列和MTg基因拷贝数以及重组酵母培养条件的优化,最终使得MTg在1 l发酵罐中高密度发酵的酶活达到7.3 u/Ml,为MTg的工业化生产奠定了基础。Direct secretory expression of active microbial transglutaminase(MTG) using heterologous hosts is a promising strategy,although its production level still needs to be improved for industrial production.Pichia pastoris is one of the most efficient expression systems developed in recent years.In this study,secretory expression of active MTG was successfully achieved by co-expressing the pro sequence and mature MTG genes in P.pastoris.Furthermore,we optimized the copy number of pro/MTG expression cassettes and the fermentation conditions.MTG production level reached 7.3 U/mL in 1-liter fermentor through high density fermentation,providing the feasiblity for industrial scale preparation of MTG.国家自然科学基金(No.31000026); 中国科学院“知识创新”工程重要方向项目(No.KSCX2-EW-G-15-03)资助~
