Neuware - An empirical study was undertaken to (a) examine various determinants influencing (de-)centralisation in Trans-World, the largest producer of television programs in Taiwan, and (b) make normative recommendations as to how insights from organisational dynamics models can be used in practice. The research was based on a sample of 63 standardised personal interviews with all Trans-World employees. Scales were particularly developed for the purpose of this study. In-depth interviews, participant observer and archival data were combined with the survey data to test a model predicting uncertainty and interdependence as primary drivers of decentralisation. Results showed that despite high uncertainty and interdependence, Trans-World was highly centralised. This apparent paradox was explained by the overriding influence of two other factors not usually modelled, including both the owner-manager's desire to control and national culture. Reduced organisational effectiveness due to this partial 'misfit' was sustainable through the company's oligopolistic power based on personal relations. Managerial recommendations included the use of a 'company profile grid' to determine the optimal degree of decentralisation.

Taschenbuch. Zustand: Neu. Neuware - As distributed applications become more sophisticated, their implementation becomes more and more difficult. It is therefore important to study how to facilitate the implementation of efficient distributed applications. This thesis reviews the different classes of distributed languages and presents a new approach to develop efficient distributed programs using the Ada language. This approach is compared in detail with existing distributed programming languages, existing approaches to distributed Ada programs, and the Distributed Annex of the new revision of Ada language.

The construction of stone lines, dikes and dams has been proven a sustainable measure which is widely accepted by the rural population of northern Burkina Faso. The objective of a field study which was conducted in Bam Province from 1992 to 1994 was to investigate economic profitability of erosion control measures under farmers' conditions on household level and for different household sub-groups. Main aspects concerned yield changes in small farmers' staple food grain production of sorghum and millet as well as the competition of rock bund construction with other dry season activities. Based on farm surveys, assessment of impact on farmers' fields, investment calculations and risk considerations examined different types of costs: construction and maintenance costs, opportunity costs of dry season activities as well as subsidies offered by development organizations. Results show a high dependence of investment on opportunity costs of family labor and the competition of dry season activities to resource conservation. Farmers' perception of weather induced harvest failure and conservation induced harvest gains makes risk an important factor in rock bund construction. Women as one of the major household sub-groups have no rock bunds on their individual plots and only gain from resource conservation by family fields. So far, it can not be guaranteed that women's economic position is stabilized by resource conservation.
