Deltagerorienteringen i undervisningen af MPA studerende – refleksioner og praksis

Praksisrelation er en vigtig bestanddel af pædagogikken på Copenhagen Business School (CBS).PÅ MPA uddannelsen er vi privilegerede i denne sammenhæng, fordi vore deltagere med en gennemsnitsalder på over 40 år selv møder op med megen erfaring. Vores opgave som undervisere og designere af uddannelsen er at skabe rammerne for, at deltagernes erfaringer kan bringes i spil ud fra mottoet »fra nærhed til distance – og tilbage igen«. Forfatteren gengiver både de mere overordnede overvejelser, man har gjort sig på uddannelsen, og en række af de mere praktiske tiltag, der har været sat i værk

A QCD Analysis of the Mass Structure of the Nucleon

{}From the deep-inelastic momentum sum rule and the trace anomaly of the energy-momentum tensor, I derive a separation of the nucleon mass into the contributions of the quark and gluon kinetic and potential energies, the quark masses, and the trace anomaly.Comment: 9 pages, MIT-CTP #2368, revtex with 1 tabl

"feelings are the motive power, reason is the rudder"

In this essay we will demonstrate that the role of project management in organisational change processes is a mixture of rational and non-rational features. It is also colourful, difficult, interesting, and messy. We have named the paper "An Essay on". An essay means treating a topic freely from different angles, although not forgetting the sources you used. The implication of this is that we are not able or willing to make an encompassing study of the literature on project management3. We thus know that many angles will not be covered. Furthermore we do not intend a make a negative delineation, indicating what we are not dealing with. We prefer to make a positive delineation, emphasising what we are going to take up in our essay. Positively phrased we are inspired by 3 sources that will make the foundation for our different angles: 1. Decision making theory (Enderud,1976)4. One of the authors has previously with success applied decision-making theory as an approach for analysing organisation change processes 5. Both authors have followed the same line in analysing organisational changes in the Danish public sector6. That success has inspired us to re-use the distinction between rational, political and anarchic processes in this essay 7. Enderud (1976:21-22) excludes explicitly the role of the actors’ participation in his presentation of decision models. We find, however this aspect so important that we have decided to include it 2. Buchanan and Boddy´s analysis of the character of change8: The authors characterise the change project in to dimensions. One pertains to the activities concerned: Are we dealing with peripheral or core activities of the organisation. The second dimension deals with the magnitude of the change. Buchanan and Boddy use the scale: incremental - radical9. Furthermore Buchanan and Boddy makes a useful distinction between "public performance" (on stage) of rationally considered and logically phased and visibly participative change and "backstage activity" in the recruitment and maintenance of support and in seeking and blocking resistance (ibid p.27) 3. We will apply data from our own case studies. We will use a format that we call an illustration, thereby indicating that we "only" illustrate a point. We do not prove it10. Our cases are almost all from the public sector or from trade unions. Most of them have been published elsewhere

Single-channel transmission in gold one-atom contacts and chains

We induce superconductivity by proximity effect in thin layers of gold and study the number of conduction channels which contribute to the current in one-atom contacts and atomic wires. The atomic contacts and wires are fabricated with a Scanning Tunneling Microscope. The set of transmission probabilities of the conduction channels is obtained from the analysis of the $I(V)$ characteristic curve which is highly non-linear due to multiple Andreev reflections. In agreement with theoretical calculations we find that there is only one channel which is almost completely open.Comment: 4 pages, 2 figures. To be published in Phys. Rev.
