The digital era has in many ways transformed the role of the public library. Today it is possible for the public to access e-media without entering a physical library building. In that context, the aim with this study is to examine the access and supply of e-media at public libraries in 76 different counties in southwestern Sweden and if librarians think it is possible for a national library service that distributes e-media to increase access to the format. In this study Buckland's theory of access and quantitative methods were used. The official statistics from the Royal library in Sweden were used as secondary data to show the exact number of e-audiobooks, e-books and databases available at the public library in every county. A survey was used to collect primary data about librarians' opinions about e-media and a national library service regarding e-media. The survey was distributed to the main libraries in the 76 counties. The results demonstrate that the access and supply of e-media differ depending on which county you live in, which can increase the knowledge gap and the social divide. It was especially Buckland's fourth aspect: the cost of the provider that influenced the public libraries supply of e-media. The survey showed that a majority of the librarians were optimistic about a national library service for distributing e-media and 91 percent thought it could increase access to the format. This study also concludes that the Swedish library law does not seem to apply to e-media.

The U.S. Southwest is a semi-arid region affected by numerous environmental problems. Chicana/o communities have been directly affected by such problems, especially ever since the region was annexed from Mexico by the United States in the mid-nineteenth century. From this moment onwards they lost their environmental sovereignty, mostly through their dispossession of the natural resources.   This environmental humanities dissertation focuses on the ethics, politics, and practices around water (management), for water is a key natural resource and a central element of Chicana/o cultural identity. It explores the ways in which Chicana/o culture is interconnected with environmental practices and sites in subaltern literary works about the Chicana/o experience. It investigates how the hegemonic Anglo-American environmental, political, and economic practices have challenged and undermined Chicana/o culture, identity, and wellbeing, and how this has been addressed in fiction; and it questions whether establishing such a connection adds any useful insights to the larger discussion on the global socio-environmental crisis. This dissertation also analyzes the writer activist character of the subaltern narratives of the corpus, with attention to the relevance of rhetoric in subverting and constructing environmental discourses and ethics.   By examining regional and border narratives, as well as fiction and non-fiction narratives about the socio-environmental struggles of other ethnic minorities in the Southwest and in other parts of the world, this dissertation puts literature about the Chicana/o experience in a regional, national, and transnational context. It moreover explores the pivotal role of literature in reclaiming environmental sovereignty, in asserting cultural identities, and in countering the environmental crisis by imagining alternative managerial practices and socio-environmental relations, as much as in challenging cultural hegemonies. / <p>QC 20170508</p>

If mitigation measures are not made to prevent global warming the consequences of a continued global climate change, caused by the use of fossil fuels, may be severe. Carbon Capture and Storage (CCS) has been suggested as a way of decreasing the global atmospheric emission of CO2. In the realms of MUSTANG, a four year (2009-2013) large-scale integrating European project funded by the EU FP7, the objective is to gain understanding of the performance as well as to develop improved methods and models for characterizing so- called saline aquifers for geological storage of CO2. In this context a number of sites of different geological settings and geographical locations in Europe are also analyzed and modeled in order to gain a wide understanding of CO2 storage relevant site characteristics. The south Scania site is included into the study as one example site with data coming from previous geothermal and other investigations. The objective of the Master's thesis work presented herein was to construct a 3D model for the south Scania site by using modeling/simulation software Petrel, evaluate well log data as well as carry out stochastic simulations by using different geostatistical algorithms and evaluate the benefits in this. The aim was to produce a 3D model to be used for CO2 injection simulation purposes in the continuing work of the MUSTANG project. The sequential Gaussian simulation algorithm was used in the porosity modeling process of the Arnager greensand aquifer with porosity data determined from neutron and gamma ray measurements. Five hundred realizations were averaged and an increasing porosity with depth was observed.   Two different algorithms were used for the facies modeling of the alternative multilayered trap, the truncated Gaussian simulation algorithm and the sequential indicator simulation algorithm. It was seen that realistic geological models were given when the truncated Gaussian simulation algorithm was used with a low-nugget variogram and a relatively large range. / Den antropogena globala uppvärmningen orsakad av användandet av fossila bränslen kan få förödande konsekvenser om ingenting görs. Koldioxidavskiljning och lagring är en åtgärd som föreslagits för att minska de globala CO2-utsläppen. Inom ramarna för MUSTANG, ett fyra år långt (2009-2013) integrerande projekt finansierat av EU FP7 (www.co2mustang.eu), utvecklas metoder, modeller och förståelse angående så kallade saltvattenakviferers lämplighet för geologisk koldioxidlagring. En del av projektet är att analysera ett antal representativa formationer i olika delar av Europa för att få kunskap angående förekommande koldioxidlagringsspecifika egenskaper hos saltvattenakviferer. Ett av områdena som har inkluderats är i sydvästra Skåne. Syftet med detta examensarbete var att konstruera en 3D modell över detta område med hjälp av modellerings/simuleringsprogrammet Petrel, utvärdera borrhålsdata samt genomföra stokastiska simuleringar med olika geostatistiska algoritmer och utvärdera dem. Målsättningen var att konstruera en modell för CO2 injiceringssimuleringar i det forstsatta arbetet inom MUSTANG-projektet. En algoritm av sekventiell Gaussisk typ användes vid porositetsmodelleringen av Arnager Grönsandsakviferen med porositetsdata erhållen från neutron- och gammastrålningsmätningar. Ett genomsnitt av femhundra realisationer gjordes och en porositetstrend som visade en ökning med djupet kunde åskådligöras. Två olika algoritmer användes vid faciesmodelleringen av den alternativa flerlagrade fällan: en algoritm av trunkerade Gaussisk typ och en sekventiell indikatorsimuleringsalgoritm. Resultaten tyder på att en realistisk geologisk modell kan erhållas vid användandet av den trunkerande algoritmen med ett låg-nugget variogram samt en förhållandevis lång range.
