Towards professionalisation? Restructuring of administrative work force in universities

This article examines the restructuring ofadministrative staff in universities throughempirically documenting such processes andproviding a theoretically foundedinterpretation and analysis of change. Theempirical material is drawn from a context ofNorwegian universities the last two decades.Two major changes can be observed in thisperiod. First, a period of steep growth inuniversity administration in early 1990sfollowed by a period of moderate growth and insome cases even decline. The second dominantdevelopment pattern in the 1980s and 1990s isthe change within administrative staff,which could be interpreted as a professionalisation of administrative staff.The article concludes by presenting possibleexplanations to the structuring of theadministrative work force in universities onthe basis of different theoretical approachesto organisational change.     

赵秉文书法略论

赵秉是金代名的书法家、理论家。长期以来，由于正统观念的桎梏，对于金代书法的研究不够深入，甚至对其评价有失公允。因而，在中国书法史上，赵秉的名字，或是片言支语，或是轻描淡写，这与事实上赵氏在书法及书论方面的成就是不相符的。本拾零考全，从家世、历官、书法、书论、艺术主张及影响等方面进行论述，以期人们对赵秉以及金代书法引起重视。     

固始鸡肌纤维生长发育规律研究

选择 2 0 0只固始鸡饲养在相同的环境条件下 ,分别于 0、2、4、6周龄各随机抽取 10只宰杀 ,对小腿肌 (腓肠机 )、大腿肌 (股胫外肌 )、胸肌 (肋提肌 )、翼肌 (臂二头肌 )肌纤维直径变化规律进行了研究 ,结果表明 :随着日龄的增加 ,不同部位纤维的直径均显著增加 (P <0 0 1) ;不同部位肌纤维直径在不同时期发育速度不同 ;肉质的改变与肌纤维的发育有关。     

Between the Academic Mathematics and the Mathematics Education Worlds

Change is always difficult, and there is no great doubt that teachers need time to come to terms with it. This fact is, however, too often forgotten. In the spirit of my earlier work, this paper is shaped by an action research perspective. It provides some insights into the learning experiences of a group of eleven experienced secondary mathematics teacher, who were enrolled in a Perspectives on Mathematics Education two semesters course, within the context of a Masters on Mathematics Teaching programme, held at a Department of Mathematics, in a Portuguese University. The first part of the paper highlights the conflicting pressures and stresses suffered, during the first semester course, by the participating teachers. Confrontation with new ideas about both mathematics and mathematics education, as well as work overload, had a damaging impact on the teachers’ self‐confidence and morale. The second part of the paper covers the second semester course by addressing three fundamental questions for teachers, which aimed at helping the students bridge the academic mathematics and the mathematics education worlds. Finally, brief scenarios of three participating teachers’ professional development throughout the course are discussed in order to illustrate the challenges they had to face and the possibilities the course (and the Masters programme) offered to promote individual change.
