    • Föreliggande studie undersöker vilka format för kartläggning och sammanställning av forskning som tillämpas i Norden. Vidare utforskas formatens relevans för Skolforskningsinstitutets uppdrag. Sammantaget har kartläggningar och sammanställningar från sex mäklarorganisationer inom utbildning, socialt arbete, samt medicin- och hälsoområdet studerats. Resultaten visar att de identifierade formaten i huvudsak bygger på en aggregativ metodik vilken i första hand är tillämpbar på frågor om hur väl olika arbetssätt och metoder fungerar. Denna inriktning utesluter stora delar av den forskning som bedrivs inom det utbildningsvetenskapliga fältet och bedöms därmed ha begränsad relevans för Skolforskningsinstitutets uppdrag. Utgångspunkten har varit att det krävs forskning från flera olika discipliner och områden för att kunna ge lärare goda förutsättningar att planera, genomföra och utvärdera verksamheten i skolan och förskolan. En viktig slutsats är därmed att Skolforskningsinstitutet behöver utveckla format för kartläggning och sammanställning som är anpassade till såväl utbildningsvetenskaplig forskning som praktik inom skolans och förskolans område.

  • Digitization of Schools and Education. The case of Sweden
  • 2019
  • Ingår i: Understanding Media and Information Literacy (MIL) in the Digital Age A Question of Democracy. - Göteborg : Department of Journalism, Media and Communication (JMG) University of Gothenburg. - 9789188212870 ; , s. 127-132
  • Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
    • In the studies presented here, digitalization of schools and education is viewed as an integral part of educational governance, situated in and related to the larger society. In this context, it can be shown that educational (digital) technology per se does not provide the solution to educational problems, nor does it have the potential to transform education culture and make teaching and learning more effective and innovative. Political decisions, together with the teacher’s educational mission, are more important in the structuring of education. This is also considered in relation to the fact that digitalization is an expanding area of education policy situated within the larger political/economic changes in societies in Western countries that have led to a fundamental reshaping of public education systems toward markets and economic competitiveness. As a consequence, educational policy, at least when it comes to digitalization, is driven by business ideas rather than broader ideas about what we want education to be for the individual and for society as a whole.

  • The effects of indexing strategy-query term combination on retrieval effectiveness in a Swedish full text database
  • 2004
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This thesis deals with Swedish full text retrieval and the problem of morphological variation of query terms in the document database. The study is an information retrieval experiment with a test collection. While no Swedish test collection was available, such a collection was constructed. It consists of a document database containing 161,336 news articles, and 52 topics with four-graded (0, 1, 2, 3) relevance assessments. The effects of indexing strategy-query term combination on retrieval effectiveness were studied. Three of five tested methods involved indexing strategies that used conflation, in the form of normalization. Further, two of these three combinations used indexing strategies that employed compound splitting. Normalization and compound splitting were performed by SWETWOL, a morphological analyzer for the Swedish language. A fourth combination attempted to group related terms by right hand truncation of query terms. A search expert performed the truncation. The four combinations were compared to each other and to a baseline combination, where no attempt was made to counteract the problem of morphological variation of query terms in the document database. Two situations were examined in the evaluation: the binary relevance situation and the multiple degree relevance situation. With regard to the binary relevance situation, where the three (positive) relevance degrees (1, 2, 3) were merged into one, and where precision was used as evaluation measure, the four alternative combinations outperformed the baseline. The best performing combination was the combination that used truncation. This combination performed better than or equal to a median precision value for 41 of the 52 topics. One reason for the relatively good performance of the truncation combination was the capacity of its queries to retrieve different parts of speech. In the multiple degree relevance situation, where the three (positive) relevance degrees were retained, retrieval effectiveness was taken to be the accumulated gain the user receives by examining the retrieval result up to given positions. The evaluation measure used was nDCG (normalized cumulated gain with discount). This measure credits retrieval methods that (1) rank highly relevant documents higher than less relevant ones, and (2) rank relevant (of any degree) documents high. With respect to (2), nDCG involves a discount component: a discount with regard to the relevance score of a relevant (of any degree) document is performed, and this discount is greater and greater, the higher position the document has in the ranked list of retrieved documents. In the multiple degree relevance situation, the five combinations were evaluated under four different user scenarios, where each scenario simulated a certain user type. Again, the four alternative combinations outperformed the baseline, for each user scenario. The truncation combination had the best performance under each user scenario. This outcome agreed with the performance result in the binary relevance situation. However, there were also differences between the two relevance situations. For 25 percent of the topics and with regard to one of the four user scenarios, the set of best performing combinations in the binary relevance situation was disjunct from the set of best performing combinations in the multiple degree relevance situation. The user scenario in question was such that almost all importance was placed on highly relevant documents, and the discount was sharp. The main conclusion of the thesis is that normalization and right hand truncation (performed by a search expert) enhanced retrieval effectiveness in comparison to the baseline, irrespective of which of the two relevance situations we consider. Further, the three indexing strategy-query term combinations based on normalization were almost as good as the combination that involves truncation. This holds for both relevance situations.

  • Nätverkspolitik - Organisering, öppenhet och kontroll i Göteborgs Sociala Forumprocess 2003 - 2005
  • 2008
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Abstract Ph.D Dissertation at Göteborg University, Sweden, 2008 Title: Nätverkspolitik. Organisering, öppenhet och kontroll i Göteborgs Sociala Forumprocess 2003 – 2005. Title: Network Politics. Organizing, openness and control in Gothenburg Social Forumprocess 2003 – 2005. Author: Niklas Hansson Language: Swedish, with an English Summary Department: Department of Ethnology, Göteborg University, Box 200, SE-405 30 Göteborg The purpose of the thesis is to analyze the production of network politics, using the Gothenburg Social Forumprocess as an example. Concepts collected from theories of social movements; the resource mobilization theory and the new social movements-theory, are brought together within the conceptual framework of assemblage theory. Assemblage theory is a theory of society reconstructed by distinguished philosopher Manuel DeLanda’s from out of late French philosopher Gilles Deleuze’s concept of assemblage, a concept describing social entities as the non-stable result of historical processes. The analysis highlights the internal dynamics of network politics, with a focus on process before stable product, putting an extra effort into explaining everyday political organizing as something highly un-predictable, as organized outcomes (network organization) cannot start with a notion of networks as a collective or community acting in unison. The study rests on solid ethnological and ethnographic ground, and is based on a long-term participant observation within the local Gothenburg Social Forumprocess, e-mailing list material, interviews with social forum-organizers, websites, and alternative media press. The empirical focus of the study is mainly on the period 2003 – 2005. Throughout the empirical chapters the local social forumprocess is analyzed via its links to other levels within the World Social Forumprocess. The World Social Forumprocess is described as a self-organizing system with constantly interacting local, regional, national, and global levels, and as an emerging network of social forum-organizations interacting via feedback processes resonating through the system. The empirical chapters highlights different parts of the production of network politics and the local social forumprocess: diffusion of the forum-model as a successful organizing format within the global justice movement, decision-making and consensus building, ground rules for interaction between political organizations, forum-organizers, individual activists and groups, the role of the Internet within network politics, selection of social categories as temporary points of convergence between different political actors (organizations), the method called merger process which reflects the forum-organization as a broker-device between organizations, power-relations within network politics, and finally, a résumé-like chapter presenting glimpses from within a local social forum-event. In the conclusion I state how the social forums could be examined as political meeting-places within a “leaderless social movement”. Keywords: social forum, networks, assemblage, territorialization, coding, social movements
