2. 11. Cascading extinctions in food webs : local and regional processes

   Author : Anna Eklöf; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cascading extinctions; complexity; connectance; dispersal; food web; local dynamics; regional dynamics; resistance; spatial structure; species loss;

   Abstract : Ecological communities all over the world are loosing biodiversity due to different kinds of human activities and there is an urgent need of understanding how those losses affect the function of the ecosystems on which we all depend. The community's response to species losses is likely to depend on both the structure of the local community as well as its interactions with surrounding communities. READ MORE

4. 12. Entropy, information theory and spatial input-output analysis

   Author : David F. Batten; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Commodity flows; dynamic analysis; entropy; information theory; input-output analysis; probability distributions; regional and interregional modelling;

   Abstract : Interindustry transactions recorded at a macro level are simply summations of commodity shipment decisions taken at a micro level. The resulting statistical problem is to obtain minimally biased estimates of commodity flow distributions at the disaggregated level, given various forms of aggregated information. READ MORE

5. 13. Systems Analysis for Eco-Industrial Development : Applied on Cement and Biogas Production Systems

   Author : Roozbeh Feiz; Mats Eklund; Jonas Ammenberg; Olli Salmi; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial ecology; eco-industrial development; multi-criteria analysis; life-cycle assessment; MCA; LCA; uncertainty management; systems analysis; industrial symbiosis; cement; biogas; cement production; biogas solutions;

   Abstract : Our industrial systems are not sustainable—a major challenge which demands several types of responses. Eco-industrial development can be seen as such a response, with the goal to establish industrial systems that are both ecological and economical. Industrial Ecology is another closely related response. READ MORE

6. 14. Firms and people in place : driving forces for regional growth

   Author : Wenjuan Li; Einar Holm; Urban Lindgren; Bo Malmberg; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; regional growth; endogenous factors; place attractiveness; population redistribution; vicinity; workplace; local area; hinterland; spatial model; Sweden; Human geography; economic geography; Kulturgeografi; ekonomisk geografi;

   Abstract : The aim of the thesis is to quantitatively study the driving forces and mechanisms for regional growth from an endogenous and exogenous perspective and reveal the most important factors contributing to regional growth, by focusing on three aspects: local labour market, the supply side and the demand side of the labour market. The thesis is designed to use Swedish micro register data to develop spatial models with higher spatial resolution. READ MORE

7. 15. Patterns and Drivers of Regional Crop Production in Chad

   Author : Erik Nilsson; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; agricultural systems; crop production; drivers; trend analysis; variability; regional analysis; Sahel;

   Abstract : Agriculture constitutes the largest economic sector and professional occupation in Chad, and is undergoing rapid changes due to processes of population increase, institutional reforms, conflicts in neighbouring countries, increasingly globalized trade networks, and environmental changes. But despite their importance for livelihoods and economic growth, the specific patterns and drivers of change in the agricultural sector are however poorly understood. READ MORE
