1. 1. Toward a cyclical model of resource alteration

   Författare :Peter Altmann; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; fine-grained; cognitive theory; Resource; practice theory; resource alteration; resource understanding; micro-level;

   Sammanfattning : Strategy work is principally about resource alteration. As managers attempt to alter their organizational resources, they need to ask two questions: “What are our resources?” and “How can we use these resources?” Managers will probably have little difficulty answering these questions in the case of tangible resources, e.g. LÄS MER

3. 2. SCALING UP RENEWABLE ENERGY TECHNOLOGIES - The role of resource mobilisation in the growth of technological innovation systems

   Författare :Kersti Karltorp; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource mobilisation.; scaling up technologies; Wind power; technological innovation system; biorefineries;

   Sammanfattning : Rapid and large-scale diffusion of renewable energy technologies is needed to avoid severe climate changes that would dramatically affect the conditions for human life on Earth. To scale up these technologies involves technological development, but also the alteration of structures that are locked-in to established socio-technical systems. LÄS MER

4. 3. Modeling Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) responses to river habitat alteration

   Författare :Kristine Lund Bjørnås; John Piccolo; Olle Calles; Steven F. Railsback; Leif Asbjørn Vøllestad; Karlstads universitet; []

   Sammanfattning : Half the world’s river volume is affected by flow alterations and/or fragmentation, a figure that is likely to increase with the current global surge in hydropower development. At the same time, freshwater biodiversity is in rapid decline. LÄS MER

5. 4. Modelling the hydrokinetic energy resource for in-stream energy converters

   Författare :Emilia Lalander; Ole Gunnar Dahlhaug; Uppsala universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Hydrokinetic energy, referring to the energy contained in moving water, is a renewable energy source that has gained much attention the past years. The energy is found in all moving water masses, but is only economical to convert for water masses moving with high velocity, i.e. likely around 1 m/s and above. LÄS MER

7. 5. The Knowledge Arena : Approaching agroforestry and competing knowledge systems - a challenge for agricultural extension

   Författare :Per Hillbur; Institutionen för kulturgeografi och ekonomisk geografi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Tanzania; coevolution; arena perspective; agroforestry; natural resource management; agricultural extension; knowledge systems; Social geography; Socialgeografi;

   Sammanfattning : Agriculture in many African countries is characterised by large diversity in production and great variation in growing conditions, irrigation potential and access to markets. This variation has proved to be a difficult matter when adjusting national agricultural policies and development projects to local conditions. LÄS MER
