Drylands is an extension of the four-day workshop on sustainable use of rangelands and desertification control held in Jeddah in November 1996.

Examining communities in all their meanings, the paper locates User- Centred Design (UCD) in the amplified scope of approaches to Information Systems Design (ISD). Culture in communities is explained in structurational terms, in which human action and social structure (including ICT) interact to produce and reproduce the social patterning that both supports and constrains action. The widening of t

In this paper we present an observer-based adaptive control scheme for robot manipulators, for which we have both unmeasured velocity and uncertain parameters. Using the observer back-stepping method, a reduced-order adaptive velocity observer can be designed independently from the state-feedback controller, which uses damping terms to compensate the presence of the estimation error in the trackin

All available literature, dealing with optical model calculations, has been reviewed to aid in assessing suitable well parameters and to indicate when the model has been successful in predicting various nuclear data. The material investigated has been indexed according to nuclide, and short abstracts have been prepared to provide a concise summary of the contents and main results. 342 references w

My paper is the introduction to my next book in the series 'The humanist as Engineer'. In my work, I have been deeply influenced by Don Ihde and his postphenomenological approach to the philosophy of technology. As Ihde’s postphenomenology, my approach is historical and differs strongly from the 'pure' phenomenological approach in spite of being connected with it through many common references. In

This book demonstrates the importance of ontology for a central debate in philosophy of mind. Mental causation seems an obvious aspect of the world. But it is hard to understand how it can happen unless we get clear about what the entities involved in the process are. An international team of contributors presents new work on this problem. In particular, they examine the nature of causes and effec

Popular Abstract in Swedish Hur är det möjligt att planera om en kommun från arbetarstad till kunskapsstad? Idag har en rad svenska och europeiska kommunledningar ambitionen att återuppfinna städer genom att tvätta bort industristaden och ersätta den med en kunskaps-, informations-, kultur-, och/eller evenemangstad. Den här formen av kommunal utvecklingsplanering har genererat en rad olika frågor What are the discursive pre-conditions for planning? In this dissertation the author analyzes and critically assesses the assumptions which underlie our thinking about planning. This is done in an analysis of firstly, how planning is legitimized, and secondly, what consequences these forms of legitimation have for planning theory as well as for planning as a political practice. The author descri

With the assumed digitalisation happening on the end-user side, progressive systems integrators stress the importance of changing the business concept from being installers to being service and solution providers. However, less is known about the details of this process on the end-user side. Based on an online survey of loss prevention managers it can be stated that security digitalisation and fur

In recent years, a number of planetary systems have been proposed to orbit-evolved binary star systems. The presence of planets is invoked to explain observed variations in the timing of mutual eclipses between the primary and secondary components of the binary star system. The planets recently proposed orbiting the cataclysmic variable system QS Virginis are the latest in this ongoing series of `

Det är ett självklart mål att myndighetsbeslut och domstolsavgöranden i skattefrågor ska vara objektiva. Det är inte möjligt att mäta graden av faktisk objektivitet. Istället hävdas i artikeln att myndigheters och domstolars organisation kan bidra till stärkande av rättssäkerhet när det gäller skattebeslut och skatteprocesser. Skatteområdet har särskilda utmaningar. Det är viktigt ur samhällssynpu
