1. 1. Dialogues on the Net - Power structures in asynchronous discussions in the context of a web based teacher training course

   Författare :Annette Johnsson; Utbildningsvetenskap; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; minority; cultural background; sex; ethnicity; gender; age; socio-economic; dialogicity; web based; computer based; CMC; net based; asynchronous; CSCL; teacher education; power structures; dialogues; Group work; team work; symbolic capital; group work;

   Sammanfattning : The general aim of this thesis is to investigate the interaction processes that occur in group dialogues when teacher students work in small groups, using net based asynchronous dialogues to solve a problem in the area of environmental sustainability. More specifically, the interest is to determine whether students’ net based dialogues give rise to patterns of dominance/subordination similar to those observed in face-to-face situations. LÄS MER

3. 2. Subjective Well-being in an Adult Swedish Population : Findings from a Population-based Study

   Sammanfattning : This doctoral thesis examines various factors associated with subjective well-being (SWB) in an adult Swedish population, aged 20-64 years, using cross-sectional and longitudinal data. The thesis includes four studies based on the PART study, a current population-based study on mental health, work, and relations in Stockholm County, Sweden. LÄS MER

4. 3. Technology-based self-service and its impact on service firm performance : a resource-based perspective

   Författare :Jinhui Wang; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Industriell marknadsföring; Industrial Marketing;

   Sammanfattning : Improving productivity is crucial for service firms to be competitive. To have customers perform certain tasks normally undertaken by employees is an important means to achieving this objective. With the aid of technology, the scale and scope of self-service has significantly increased in recent years. LÄS MER

5. 4. Fungi-Based Biorefinery : Valorization of industrial residuals and techno-economic evaluation

   Författare :Gülru Bulkan; Mohammad J Taherzadeh; Mats Galbe; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Techno-economic analysis; Organosolv; bioethanol; filamentous fungi; food; lignin; fruit; bioactive compounds; Resource Recovery; Resursåtervinning;

   Sammanfattning : Sustainable development of society and industry is necessary for a safer future that is being challenged by environmental pollution, climate change, and scarcity of food and nutrition. Materials considered as waste can be converted into value-added products and energy, hence regained to the economy. LÄS MER

7. 5. Multilayer Structures for Biomaterial Applications : Biomacromolecule-based Coatings

   Författare :Tobias Halthur; Per M. Claesson; Bjørn Stokke; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multilayer; layer-by-layer deposition; physical chemistry; surface chemistry; adsorption; ellipsometry; QCM-D; DPI; protein adsorption; polypeptides; biomaterials; biosurfaces; amelogenin; solid liquid interface; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : The cellular response to a biomaterial, such as a dental implant, is mainly governed by the surface properties, and can thus be altered by the introduction of a surface coating. In this thesis the buildup of a biomacromolecule-based coating formed by layerby-layer (LbL) deposition of the charged polypeptides poly(L-lysine) (PLL) and poly(L-glutamic acid) (PGA) has been studied.
