Looking ahead, the quest for environmental sustainability may turn out to be the most important political challenge of the twenty-first century. Though consensus is growing about some of the policy objectives like climate stability, political attitudes to these issues remain highly contested. Political parties seem to differ on both ontological assessments (how severe are the problems) and remedia
It is argued that the capacity to focus attention is crucial for intentional communication. Intentional communication is goal-intended; directed at changing mental states and as a consequence behaviour; about a referential object common to sender and recipient; and about objects that may be context-and referent-independent. Three different kinds of attention is discerned: scanning, attention attra

Automation is increasingly important in producing and maintaining cartographic data sets. This thesis deals with automatic methods to propagate updates between cartographic data sets. The major idea is to update only the most detailed data set (master data set) and then propagate these updates automatically to less detailed data sets (target data sets). The approach used is firstly to formulate li
This paper presents a highly linear receiver frontend operating from 700 MHz to 3.7 GHz with 3rd order harmonic rejection. It consists of a complementary low noise transconductance amplifier with capacitive cross coupling and negative gm current sources, a six phase current-mode passive mixer, and baseband transimpedance amplifiers providing programmable gain. The circuit has been fabricated in 65
This thesis consists of five papers on the subject of statistical modeling of stochastic networks. The NG-model proposed in Paper I combines a block structure with parameters that capture the identities of vertices and thus the new approach stresses the concept of ego-nets, which describes the structure around identified vertices. The models proposed in Papers II-V are closely related to the NG-mo
