1. 1. The institutionalisation of validation and the transformation of vocational knowledge : The case of admission into Vocational Teacher Education in Sweden

   Författare :Maria C. Johansson; Per Lindqvist; Lazaro Moreno Herrera; Linnéuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; agency; competence; institutional arrangements; institutional conditions; institutionalisation; validation; vocational knowledge; qualification framework; Pedagogics and Educational Sciences; Pedagogik och Utbildningsvetenskap;

   Sammanfattning : The aim of this thesis was to understand the validation of vocational knowledge prior to entry into vocational teacher education in Sweden with regard to conceptions and understandings of vocational knowledge, and also to understand how institutional conditions, such as ideas of how to organise validation, influence the content and form of the validation practice. From this aim the following research questions were developed: What ideas about the organisation of validation stand out in the policy and practice of validation? What conceptions and understandings of vocational knowledge is the organisation of validation built on and what do they entail? Who has the agency to describe and decide upon vocational knowledge in the policy and practice of validation? What institutional arrangements appear in the practice of validation?To conduct the studies in the thesis a multimethods approach was adopted, combining policy analysis and interviews. LÄS MER

3. 2. Improvements of the Bromodeoxyuridine-DNA Flow Cytometry Method for the Study of Cell Proliferation

   Författare :Maria C Johansson; Bröstcancer-genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; head and neck cancer; [3H]thymidine; energy transfer; cell cycle; xenografted tumours; cultured cells; potential doubling time; labelling index; DNA synthesis time; cell proliferation; growth kinetics; Bromodeoxyuridine; DNA flow cytometry; cancer; onkologi; Cytologi; cancerology; oncology; Cytology;

   Sammanfattning : Potential doubling time (Tpot), DNA synthesis time (TS), and labelling index (LI) are fundamental growth kinetics parameters in clinical and experimental cancer research, which may be of further practical importance regarding prognosis and treatment prediction of cancer. They can be measured by bromodeoxyuridine(BrdUrd)/flow cytometry (FCM) methods, where BrdUrd, an analogue of thymidine, is incorporated into DNA and quantified simultaneously with the DNA content.

5. 4. Packing effects in palladium(II) and platinum(II) compounds, X-ray crystallography

   Författare :Maria Johansson; Kemiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Platinum II ; Palladium II ; Half-normal probability plots; X-ray crystallography; Packing effects; Oorganisk kemi;

   Sammanfattning : This thesis focuses on i) the effect of packing on the molecular geometry ii) packing arrangements of neutral Pd(II) and Pt(II) complexes iii) the trans influence in Pt(II) complexes iv) the differences in bonding in corresponding Pd(II) and Pt(II) complexes and v) the geometry of Pd(II) complexes with potential catalytic properties. Detailed three-dimensional structural information at the atomic level can be obtained from X-ray crystallography. LÄS MER

7. 5. NMR Studies of Bacterial Albumin-Binding Modules

   Författare :Maria U Johansson; Biofysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Biotechnology; Bioteknik; Proteins; enzymology; Proteiner; enzymologi; Physical chemistry; three-helix bundle; protein structure; protein PAB; protein-protein interactions; protein G; protein dynamics; NMR; module shuffling; GA module; evolution; albumin-binding; bacterial surface proteins;

   Sammanfattning : Peptostreptococcus magnus and group C/G streptococci are Gram-positive cocci that are part of the normal flora and reside in more or less the same locations in the host. Protein G of group C/G streptococci was originally described as binding IgGFc of several species and later shown to also bind human serum albumin and albumins from various animal species. LÄS MER
