Institution ger 250 miljoner träffar på sökmotorn Google. I vilka sammanhang används detta slitstarka ord och vilka betydelser bär det på? I den här boken undersöks institutioner som platser, rum och organisationer samt begreppets vetenskapliga utveckling och användning. Institutioner representerar ofta socialt tvång, beständighet över tid och reglering av aktörers handlande.

Nationality originated along with development of the modern nation-State. However, growing global migration, travel and increasing communications have led to creation of multiple individual loyalties in addition to national identity. This is further facilitated by mobility of capital, foreign investment, and establishment of transnational corporations. Dismantling national borders and granting di

We derive explicit density evolution equations for protograph-based generalized LDPC codes on the binary erasure channel. They are obtained from an analysis of multi-dimensional input/output transfer functions of the component decoders. Belief propagation decoding with optimal component APP decoders is considered. Based on the resulting transfer functions, a threshold analysis is performed for som

Popular Abstract in Swedish Ta en titt på min hemsida för en kort sammanfattning av mitt arbete. Där finns dessutom kartor och foton m.m. Det kommer även att finnas en komplett nerladdningsbar version av avhandlingen. http://www.geol.lu.se/personal/FKH/shome.htmlThis thesis deals mainly with age-investigations of metasedimentary and magmatic rocks of Ny Friesland, located in the northeastern Svalbard. However, the provenance of quartz-porphyry clasts in a Devonian conglomerate have also been investigated in northwestern Svalbard. This information is important for reconstructions of plate movements in the high Arctic during the Caledonian orogeny and earli

The SCR technique is used (1998) in five Swedish wood fired CHP plants. These plants are among the first references in the world for SCR in combination with bio fuels. The experiences show some problems with the catalyst function because of deactivation and ash-plugging. The deactivation has been handled by seasonal washing of the catalyst. In this work the cause for and the extent of catalyst dea

Liberalisation and deregulation of public utility sectors has been introduced in several European countries. In 1994 Swedish municipalities were instructed to reorganise waste collection routines by enlarging the number of fractions to be able to reuse waste fractions in an environmental benign way. The public waste sector have to a considerable extent been diversified and deregulated. At the same

Sex allocation is an important field in evolutionary biology, both historically and currently. However, while sex allocation theory has successfully predicted sex ratio bias in some taxa, most notably parasitic wasps, vertebrates are notorious for their poor fit to theoretical models. We argue that this arises from the use of very complex model systems to test relatively simple theoretical models.
