  • I främsta rummet planerandet av en högskolebiblioteksbyggnad med studenters arbete i fokus
  • 2009
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • The purpose of the thesis is to investigate planning processes for academic library buildings and the outcomes of such processes. This is accomplished through a case study utilising discourse analysis. The main question is: How is a vision of an academic library implemented in and through a building? The case study is retrospective and focused on the building of a new library at Kalmar University, Sweden, at the end of the 1990s. During this period, technological and educational developments and general societal change transformed the context of library planning and made way for renegotiations of the librarian profession. A critical realist approach characterises the study of visions, processes and the analysis of the various functions of the building. Results reveal the proactive nature of the activities of the library director in Kalmar. Early in the process he formulated a vision in which he presents the library as an information resource, a meeting place between different user groups and a workplace intended to promote learning and knowledge. From a professional point of view, the vision implied a dehierarchisation of relations both within the library staff and between library staff and visitors. The vision was based on an interpretation of Swedish national educational policy, and architecturally manifested by an ambition to reduce the physical and psychological boundaries between library staff and visitors. The early formulation of the vision together with the clients’ use of architectural expertise facilitated the choice of architects. However during the process a need arose to anchor the decision in the library field. Efforts were made to address library expertise and to collect user comments from a broader academic field. Discourses concerning the university library as a workplace and a meeting place were especially evident in the strategies of the leading agents. The discourses uncovered in the study correspond to more general discourses which became prominent in society and higher education during the period in question. The library itself has met growing appreciation by users both from within and outside the university. The proactive leadership demonstrated by the library director in Kalmar was based on hegemony rather than coercion. This corresponds to contemporary tendencies. Hegemonic consent may persist even after changes in leadership. In Kalmar however, architectural solutions with insufficient support from the library staff have been reconstructed after changes in leadership. Future research on architectural planning processes may pay further attention to different discursive resources, social fields and the positions within them.

  • The effects of indexing strategy-query term combination on retrieval effectiveness in a Swedish full text database
  • 2004
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • This thesis deals with Swedish full text retrieval and the problem of morphological variation of query terms in thedocument database. The study is an information retrieval experiment with a test collection. While no Swedish testcollection was available, such a collection was constructed. It consists of a document database containing 161,336news 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 testedmethods involved indexing strategies that used conflation, in the form of normalization. Further, two of these threecombinations used indexing strategies that employed compound splitting. Normalization and compound splittingwere performed by SWETWOL, a morphological analyzer for the Swedish language. A fourth combinationattempted 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 tocounteract 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 relevancesituation. With regard to the binary relevance situation, where the three (positive) relevance degrees (1, 2, 3) weremerged into one, and where precision was used as evaluation measure, the four alternative combinationsoutperformed the baseline. The best performing combination was the combination that used truncation. Thiscombination performed better than or equal to a median precision value for 41 of the 52 topics. One reason for therelatively good performance of the truncation combination was the capacity of its queries to retrieve different partsof speech.In the multiple degree relevance situation, where the three (positive) relevance degrees were retained, retrievaleffectiveness was taken to be the accumulated gain the user receives by examining the retrieval result up to givenpositions. The evaluation measure used was nDCG (normalized cumulated gain with discount). This measurecredits retrieval methods that (1) rank highly relevant documents higher than less relevant ones, and (2) rankrelevant (of any degree) documents high. With respect to (2), nDCG involves a discount component: a discount withregard to the relevance score of a relevant (of any degree) document is performed, and this discount is greater andgreater, 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 thebaseline, 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 alsodifferences between the two relevance situations. For 25 percent of the topics and with regard to one of the four userscenarios, the set of best performing combinations in the binary relevance situation was disjunct from the set of bestperforming combinations in the multiple degree relevance situation. The user scenario in question was such thatalmost 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 situationswe consider. Further, the three indexing strategy-query term combinations based on normalization were almost asgood as the combination that involves truncation. This holds for both relevance situations.

  • Att vara invandrare och patient i Sverige Ett individorienterat perspektiv
  • 2008
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • This thesis focuses on immigrants in Sweden. What experiences from the meeting with Swedish society do immigrants have and what meaning does the immigrant background have when they have been patients within the Swedish health and medical service? Former research about patients with an immigrant background can be divided into two perspectives. One which illuminates ethnically demarcated immigrant groups and specific needs. The other perspective has an individually adopted approach independently of the patients’ ethnical background. Here it is mainly the communication problems that are stressed, since these make it hard to understand the individual’s needs.The two empirical studies of the thesis start from an individualised perspective, a life world perspective. Research data have been collected through open interviews.The overall purpose was to develop a deepened understanding of what it means to live as an immigrant in Sweden and receive care. The aim of the pre-study was to examine immigrants’ experiences of participation in municipal home care. In the main study the overall purpose was used and two research questions were asked: What do persons with an immigrant background have to tell us about their situation in Swedish society? How does the situation as an immigrant in Sweden influence the experience of being a patient in Swedish health and medical care?The pre-study shows that participation means making demands and meeting caregivers who view the patient as an actor with the right to make his or her own decisions. One important postulate seems to be access to a good interpreter. To refrain from participation seems to be about adopting a passive attitude as a patient. It seems as if it is the caregivers who are the active ones and the ones setting the standards for the contents of the care. To experience not being invited to participation mainly seems to originate from the fact that the interviewees could neither understand nor make themselves understood. One consequence is that patients are just looked upon as carriers of a symptom.The main study shows that the interviewees’ existential existence as patients involves the whole life situation. Different forms of unsurmountable difficulties might reinforce each other. The ambition to establish oneself in a new home country might therefore be passivised. For patients with immigrant background earlier experiences from exposed situations seem to influence how the patients feel about their treatment. The additional knowledge is that problems seem to reinforce each other. Patients with an immigrant background must be treated as individuals. Every individual’s story has to be made visible.The thesis shows that caregivers ought to endeavour to understand the individual. To encourage dialogue, despite language problems, is of importance for the patient to be able to express his or her needs. The use of an interpreter may have a positive influence on these patients’ possibilities to exert an influence. This means that caregivers who consult an interpreter should build up their competence to communicate through an interpreter.

  • Bibliotekarien om yrkets tidiga innehåll och utveckling
  • 2010
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • This thesis is about librarians and librarianship. Questions asked in the thesis are how the librarianship developed between 1475 and 1780 and what the core and the main tasks of the profession were. There is also the question whether the profession is built on a common basis to rely on and if it is characterized by unique knowledge. The history of the librarian is divided in three parallel ongoing parts, the practical, the visionary and finally the personal, the librarians own attitudes. The practical area is characterized by the practical work, as cataloguing, classification, care of books, shelving and protecting the documents in different ways from several possible threats. The work is dictated by the employer. The visionary part complements and develops the methods of library work being established in the practical area, the librarians themselves formulate their thoughts of libraries and librarianship, defines the roles of libraries in society, in education and research. The librarians think about the content of the work and the future of libraries. These two areas done, another dimension is born. That is the ethics of the librarianship, how to behave and how to act towards library users and this dimension puts the librarian in the centre. There have been signs of this before but the completion is done in 1780 by Cotton des Houssayes. His speech opens the future for the librarians to come. The time period covers 305 years from 1475 until 1780. Starting point for this research about the librarian is 1475 because in that year pope Sixtus IV appointed Bartolomeus Platina as librarian of the Vatican library. The bull of 1475 is an official document that describes the librarian as a librarian and that he is told what to do, where to do it, how to do it and why. Jean-Baptiste Cotton des Houssayes, appointed in 1780, sets an end to this period with his speech to the General Assembly of the Sorbonne university in Paris. His speech completes the creation of the librarian. It is also the starting point of something new in librarianship. The common tasks of the librarians investigated, reveal what can be regarded as the essence of librarianship. From the practical area, the employers gave the librarians their tasks, executed at different places in different kinds of libraries. From the area of visions, the librarians built their visions as a continuum of the experiences from the practical work. New areas like the role of the librarian, the goals for the library itself and the librarians as the executors and pathfinders for the future. More of theory became a natural part of the librarianship. The last area of the development of the librarian is to adopt ethical aspects of their profession. This dimension is a self-reflecting attitude important to the librarians themselves.

  • On axioms and images in the history of Mathematics
  • 2007
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • This dissertation deals with aspects of axiomatization, intuition and visualization in the history of mathematics. Particular focus is put on the end of the 19th century, before David Hilbert's (1862–1943) work on the axiomatization of Euclidean geometry. The thesis consists of three papers. In the first paper the Swedish mathematician Torsten Brodén (1857–1931) and his work on the foundations of Euclidean geometry from 1890 and 1912, is studied. A thorough analysis of his foundational work is made as well as an investigation into his general view on science and mathematics. Furthermore, his thoughts on geometry and its nature and what consequences his view has for how he proceeds in developing the axiomatic system, is studied. In the second paper different aspects of visualizations in mathematics are investigated. In particular, it is argued that the meaning of a visualization is not revealed by the visualization and that a visualization can be problematic to a person if this person, due to a limited knowledge or limited experience, has a simplified view of what the picture represents. A historical study considers the discussion on the role of intuition in mathematics which followed in the wake of Karl Weierstrass' (1815–1897) construction of a nowhere differentiable function in 1872. In the third paper certain aspects of the thinking of the two scientists Felix Klein (1849–1925) and Heinrich Hertz (1857–1894) are studied. It is investigated how Klein and Hertz related to the idea of naïve images and visual thinking shortly before the development of modern axiomatics. Klein in several of his writings emphasized his belief that intuition plays an important part in mathematics. Hertz argued that we form images in our mind when we experience the world, but these images may contain elements that do not exist in nature.

  • Evaluation of various strategies to improve outcome after out-of-hospital cardiac arrest with particular focus on mechanical chest compressions
  • 2010
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • Cardiopulmonary resuscitation (CPR) skills vary among health care professionals. A previous study revealed that chest compressions were only performed half the time in out-of-hospital cardiac arrest (OHCA). Field conditions and fatigue could be possible explanations. The aim of this thesis was to study the impact of the introduction of mechanical chest compression in OHCA according to survival and its usability and b) passive leg raising (PLR), to augment the artificial circulation, during CPR. ... mer Methods: This thesis is based on a pilot study conducted in the Gothenburg/Mölndal and Södertälje Emergency Medical Service systems in 2003-2005. Witnessed OHCA (adult >18 years) received either mechanical (n=159) or manual (n=169) chest compressions. The pressure of end-tidal carbon dioxide (PETCO2) has been shown to correlate with cardiac output (CO) during CPR. To compare the effect of the different strategies, the PETCO2 was measured, during CPR, with standardised ventilation. Result: PLR during CPR increased the PETCO2 value within 30 seconds. Mechanical active compression-decompression (ACD) CPR, compared with manual compressions, produced the highest mean of initial, minimum and average values of PETCO2. However, mechanical chest compressions did not appear to result in improved survival. Clinical circumstances such as unidentified cardiac arrests (CAs) resulted in a large drop-out in the intervention group or a late start to the intervention in relation to CA. The late start meant that the intervention targeted a high-risk population with a low chance of survival. The majority of identified CAs were coded by the Rescue Co-ordination Centre (RCC) according to symptoms (usually unconsciousness), while the minority were coded according to the diagnosis of CA. Patients coded according to the diagnosis of CA had an earlier start of CPR, a higher rate of bystander CPR and a tendency toward higher survival rates. Conclusion: Since PLR during CPR appears to improve circulation after OHCA, larger studies are needed to evaluate its potential effects on survival. Compared with manual compressions, mechanical ACD CPR produces probably the most effective CPR. However, different clinical circumstances make the device difficult to study outside hospital. Coding a CA according to diagnosis rather than symptoms appears to improve the out-of-hospital care.

  • Changing practice by reform the recontextualisation of the Bologna process in teacher education
  • 2013
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • The purpose of the thesis is to investigate a specific case of curriculum change; that of organizing teacher training courses around learner outcomes in line with the Bologna process. The investigation is an example of a practitioner research case study and looks at how official Bologna policy messages are re-interpreted and recontextualised at the local micro level. A variety of methods are used to collect and analyse the data produced. A form of discourse analysis, as well as a survey of research literature, is used to identify policy discourses connected with the Bologna process. At the local micro level, local documentation as well as teacher talk in planning meetings are analysed to throw light on how the Bologna process was implemented. A number of discourses were found in policy documents; including the need to modernize higher education and to move towards a more student centred approach to learning. The thesis shows that these discourses were mediated locally by a regulative discourse portraying teachers as role models who have the task of passing on knowledge that is essential for the students to obtain before entering the profession. Instead of challenging the pedagogic identities for teachers and students, the introduction of learning outcomes acted to strengthen the fundamental vertical relations between teachers and students, cementing and confirming the level of control that teachers had over all aspects of the curriculum. Changes made in connection with the introduction of learning outcomes had a minimal influence on practice and were contested by some teacher educators. Teacher educators resisted and mediated the changes made by continuing to use their traditional practices.
