Usually, in monocentric city models, the spatial patterns of segregated ethnic groups are assumed to be ring-shaped, whereas in the 1930ies Hoyt showed that empirically wedge-shaped areas predominate. In contrast to Rose-Ackerman.s discussion of the in.uence within a ring-shaped pattern which the aversion which different households in the context of racism have, Yinger showed that, depending on the population mix, a wedge-shaped pattern may arise if it is border length which causes the spatial pattern. In this contribution, a simulation based on a monocentric city model with two or more different household groups is used to derive spatial patterns. Wedge-shaped segregation is shown to be the result of positive externalities among similar households. Differences between households only lead to ring-shaped patterns if the e¤ect of a city center on spatial structure dominates neighborhood e¤ects. If more than two groups of households are being considered, mixed patterns of concentric and wedge-shaped areas arise.
In Organisationen mit mehreren hundert oder mehr Mitarbeitern ist es kaum möglich, einen Überblick über die Kompetenzen und Spezialkenntnisse von Beschäftigten zu behalten. Die Suche nach Fachleuten gestaltet sich dann oft schwierig, zum Beispiel wenn ein Projektteam zusammengestellt werden soll. Hilfe versprechen Skill- Management-Systeme, vorausgesetzt, ihre Datenbank wurde sinnvoll eingerichtet und wird laufend aktualisiert. Die Autoren beschreiben Aufbau und Struktur derartiger Systeme, fragen nach ihren kosten und nennen Kriterien für professionelle Lösungen.
Skill management catalogues built via KMDL : integrating knowledge and business process modelling
(2004)
The efficient use of human capital is one of the most important factors in todays' business competition. Competition is strongly influenced by qualified staff. In order to aid the human resources department to keep up with strategic decisions various skill management systems have been created that make the development of human resources easier and more precise. Skill management systems are only as good as the information that they are based on. The mostly used basic information is the skill catalogue which shows the gaps of each employee or division within the company. But there are nearly no applicable methods yet to create such a catalogue thoroughly. This paper introduces a reasonable approach to create such a catalogue with the description language for knowledge-intensive processes KMDL. The skill catalogue built for skill management systems is one of the most important but still most neglected factors when introducing skill management.
Revisiting public investment
(2004)
The consumption equivalence method is the theoretical basis of public cost-benefit analysis. Consumption equivalence public capital prices are explicitly introduces in order to sufficiently care for the opportunity cost of public expenditure. This can solve the dispute about the social rate of discount within public cost-benefit analysis witch was generated on a criterion looking similar to the capital value formula, known as Lind’s approach. The social rate of discount is liberated from opportunity costs considerations and the discounting away of the effects for future welfare vanishes. The corresponding question whether one should accept a positive value of the pure rate of social time preference is an old issue. Its current state between the prescriptive and descriptive view can also be interpreted as a consequence of the oversimplification of standard cost– benefit analysis. But apart from an economic self-process the pure rate of social time preference is also defined as a business-as-usual value of social distance discounting. Hence, a political choice has to be made about this rate which is free in principal.
Knowledge is more and more a key factor within companies [10]. Nearly 40 percent of all employees are so called 'knowledge workers'. Distribution and inquest of knowledge within companies are supported by skill management systems. Although not all aspects and potentials of this instrument are yet utilized skill management systems have spread widely within business organizations. This paper summarizes the requirements, scopes and problems for skill management system within the company.

Optimal spatial patterns of two, three and four segregated household groups in a monocentric city
(2004)
Usually, in monocentric city models the spatial patterns of segregated household groups are assumed to be ring-shaped, while early in the 1930ies Hoyt showed that wedge-shaped areas empirically predominate. This contribution presents a monocentric city model with different household groups generating positive externalities within the groups. At first, border length is founded as a criterion of optimality. Secondly, it is shown that mixed patterns of concentric and wedge-shaped areas represent multiple equilibria if more than two groups of households are being considered. The welfare optimal segregated pattern depends on the relative purchasing power of different household groups.
Die Ressource Wissen als Bestandteil der unternehmerischen Wertschöpfung hat in den letzten Jahren stark an Bedeutung gewonnen. Besonders davon beeinflusst sind Branchen und Geschäftsmodelle, deren Wertschöpfung zu einem Großteil auf Erwerb, Erzeugung und Nutzung von Wissen basiert. Bekannte Werkzeuge für die Geschäftsprozessmodellierung berücksichtigen in der Regel nur explizites Wissen, welches in statischer Form abgebildet wird. Dabei gerät die Betrachtung von personenbezogenem Wissen, welches nicht unmittelbar zur Erzeugung von Informationen benötigt wird, aus dem Blickfeld. In diesem Beitrag werden klassische Verfahren der Modellierung von Geschäftsprozessen auf ihre Eignung zur Darstellung wissensintensiver Geschäftsprozesse untersucht. Basierend auf den vorgefundenen Defiziten wird der Modellierungsansatz KMDL (Knowledge Modeling Description Language) vorgestellt.
The Knowledge Modeler Description Language KMDL is able to represent the creation, use and necessity of knowledge along common business processes. So KMDL can be used to formalize knowledge-intensive processes with a focus on certain knowledge-specific characteristics and to identify weak points in these processes. For a computer-aided modeling and analyzing the tool K-Modeler is introduced.
