Regionalisering och regionalism : idé, ideologi och politisk verklighet (Rapport i projektet Regionalisering och flernivådemokrati)

Under de senaste 20 åren har ordet region gjort ett minst sagt stormande intåg i det politiska språket ute i Europa, och under det senaste decenniet så även i Sverige. I det Europa som håller på att växa fram förmodas just regionen spela en alltmer central roll som ett politisk självstyrande område mellan den centrala och den lokala nivån. Vilka idéer och tankegångar är det egentligen som driver d

Lab Scale Simulation of a Leak in a Landfill Cover

Many Swedish landfills are currently applied with a final cover. To minimise costs and the use of natural resources, waste materials can be a suitable substitute in landfill covers. Depending on the wastes’ contents, their mobility and in which layer of the final cover they are used, they could potentially contribute to the emission potential of the landfill. In this study the impact on landfill l

Characterization of process streams in TMP and CTMP pulp mills

Samples of process streams were withdrawn at various positions at one groundwood, four thermomechanical (TMP) and two chemical thermomechanical (CTMP) lines in four different pulp mills. Samples were divided in fractions by size exclusion chromatography (SEC). Concentration of sugars in each fraction was determined by high-performance anion exchange chromatography. The separate, but close response

Why internal validity is not prior to external validity: Paper presented at PSA 2012

In Persson & Wallin (2012) we show that the common claim that internal validity should be understood as prior to external validity has, at least, three epistemologically problematic aspects: experimental artefacts, the implications of causal relations, and how the mechanism is measured. Each aspect demonstrates how important external validity is for the internal validity of the experimental re
