Algorithms for restricted least absolute value estimation

We present a concise summary of recent progress in developing algorithms for restricted least absolute value (LAV) estimation (i. e. ?₁ approximation subject to linear constraints). The emphasis is on our own new algorithm, and we provide some numerical results obtained with it.

Der Change Explorer — ein Instrumentarium zur Exploration und Beratung von Veränderungen in Organisationen

The Change Explorer is a multimethod tool for the evaluation of and improvement in the change management process. It has been developed based on an integrative systemic change management theory. The contribution describes the theoretical background and different modules, like the interview with card and structure analysis techniques, questionnaires, and results workshop, performed with the key persons involved in the changes. Flexible application possibilities, high practice acceptance and typical results are shown by three project examples. The first is a scientific research study on changes at the police; the second is an applied evaluation and improvement project of the change management at all important changes of a group of companies, and the third is an explorative study of change management in bicultural teams. The tool promotes common self-reflection under consideration of the different perspectives of the key persons involved. This allows developing improvements in the change management in a workshop of the interview partners, better supported by common experience. Important is here particularly the recording of concrete qualitative information on evaluation criteria and success factors by the interviews besides the assessment of quantitative data.     

Begleiterscheinungen projektförmig organisierter Mediationsverfahren

In large scale environmental mediations research instituts often had an important role. Frequently they took the initiative, operated as projekt managers, as mediators and analysed the processes and the results of the mediation. The management of mediations by research instituts has various effects on the procedural process and the evaluation of the results. The interaction of science and practice can cause constructive synergy effects as well as mutual obstructions. Subject of this aricle are in particular the related problems, which can be generated if a mediation is organised as a research projekct.     

Der Masterplan und sein Weg durch die Organisation

Organizations in the public sector, like the German police, are under increasing pressure to change in the face of new challenges. We discuss the complexity of change projects based on qualitative interviews with future top managers in the police. It emerges that employees do not faithfully implement top down change plans. Instead, they subject change plans to various adaptations based on their active sense-making which is influenced by cognitive and behavioral patterns of the organizational members. These micro processes of change severely restrict the plan-ability of change projects. Flexible and reflective procedures are required to successfully manage change, as plans are more often adapted as their champions ever intended.
