  1. 21. Constructing Consumer Knowledge in Market Research : An Ethnography of Epistemics

    Författare :Johan Nilsson; Claes-Fredrik Helgesson; Lotta Björklund Larsen; Franck Cochoy; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; market research; commissioned knowledge production; epistemics; Sweden; marketing; ESOMAR; ethnography; epistemography; epistemic culture.; marknadsundersökningar; uppdragsbaserad kunskapsproduktion; det epistemiska; marknadsföring; ESOMAR; etnografi; epistemografi; kunskapskultur;

    Sammanfattning : Market research pervades society. It is an endeavour that connects marketing practice with methods similar to social science. Further, market research results appear as knowledge produced to inform recipients towards making productive business decisions and as a commodity sold to commissioning clients. LÄS MER

  3. 22. Generalized anxiety disorder (GAD) and anxiety symptoms in older adults

    Författare :Johan Nilsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anxiety; Worry; GAD; Epidemiology;

    Sammanfattning : Anxiety is a broad concept, difficult to detect and recognize. Expression may shift over the lifetime further complicating identification. Generalized Anxiety Disorder (GAD) is one of the most common anxiety disorders in older adults; however, the true nature remains unclear. LÄS MER

  4. 23. Operando X-ray Absorption Spectroscopy Studies of Methane Oxidation Catalysts

    Författare :Johan Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; operando spectroscopy; XAS; palladium; heterogeneous catalysis; methane oxidation; XAFS;

    Sammanfattning : Operando spectroscopy is an experimental method in catalysis that combines measurements of catalytic activity and selectivity with simultaneous in situ spectroscopic characterization of the catalyst. Since the structure and composition of the catalyst are probed under reaction conditions, the method can provide valuable information to elucidate the mechanism of the studied reaction. LÄS MER

  5. 24. Studies on Oxidative Couplings in H-Phosphonate Chemistry

    Författare :Johan Nilsson; Jacek Stawinski; Esther Kuyl-Yeheskiely; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oxidative coupling; H-phosphonate; H-phosphonothioate; organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : In this thesis oxidative coupling of H-phosphonate and H phosphonothioate diesters with different alcohols and amines are presented. Since the reactions with alcohols previously have been particularly unfavourable due to competing side reactions, a modified protocol leading to high coupling yields of structurally diverse hydroxylic components was developed.

  7. 25. Spatial organization of retail activities

    Författare :Helena Nilsson; Johan Klaesson; Sven-Olov Daunfeldt; Özge Öner; Daniel Arribas-Bel; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis is a compilation of four independent papers that examine the spatial process of retail location. The central question I ask is how changes in access to consumer demand affects retail in terms of size and survival. LÄS MER
