1. 21. Investigating Spatial Data Infrastructure Planning in Tanzania using System Modelling and Social Concepts

   Författare :Alex Lubida; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spatial Data Infrastructure; System Dynamics technique; Agent Based Modeling; Community of Practice; Multi- Objective Optimization; Land use planning;

   Sammanfattning : Spatial Data Infrastructure is one of the requirements for sustainable development and many countries worldwide are at different stages of implementation. Several researchers have shown that SDI has helped governments to recover funds due to reduction in duplication of efforts and also has increased efficiency in resource management and planning.

3. 22. Modelling phase separation in Fe-Cr alloys : A continuum approach

   Författare :Thomas Barkar; John Ågren; Nele Moelans; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase separation; spinodal decomposition; nucleation; diffusion; thermodynamics; kinetics; steel; ferritic;

   Sammanfattning : The formation of Cr-rich and Fe-rich domains upon ageing of an initially homogeneous Fe-Cr alloy at elevated temperatures (300-600 ºC) is commonly referred to as phase separation. The behaviour originates from a miscibility gap in the Fe-Cr phase diagram. LÄS MER

4. 23. Preventing Adolescent Alcohol Use: Processes and Outcomes of a Community-Based Intervention in Trelleborg

   Författare :Martin Stafström; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alcohol prevention; Community-based intervention; Public health; alcohol-related accidents alcohol-related violence; institutionalization; effect evaluation; process evaluation; epidemiology; Folkhälsa; epidemiologi; adolescents;

   Sammanfattning : The aim of this thesis is to investigate the potential of applying a community-based intervention, implemented in the Swedish city of Trelleborg 1999-2002, to reduce adolescent alcohol use. In order to do so, we had four specific aims. First, we studied the processes, both in terms of action and institu-tionalization, within the intervention. LÄS MER

5. 24. A Systems Tool for Prescriptive Policy Analysis : Labelled Causal Mapping Method for Policy-oriented Modelling, Simulation and Decision analysis

   Författare :Osama Ibrahim; Aron Larsson; David Sundgren; Maja Schlüter; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Public Policy; Systems analysis; Causal mapping; Policy modelling and simulation; Policy evaluation; Computer and Systems Sciences; data- och systemvetenskap;

   Sammanfattning : The elicitation and processing of relevant information is the core of any policy decision-making process. Modelling is about making sense of the available information. Models are able to incorporate the contextual influences on policy making (e.g. LÄS MER

7. 25. Petermann Glacier Ice Shelf in a warming world : Insights from 3-D numerical modelling of ice shelf-ocean interactions at Petermann Fjord, Northwest Greenland

   Författare :Abhay Prakash; Nina Kirchner; Qiong Zhang; Riko Noormets; Hans Burchard; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; Greenland; ice shelf-ocean interactions; numerical ocean modelling; naturgeografi; Physical Geography;

   Sammanfattning : The Greenland Ice Sheet (GrIS) is currently the largest contributor to global mean sea level rise, and contemporary mass loss rates are likely lower bounds for the rates to be observed in decades to come. At present, marine outlet glaciers along the northern GrIS margin, with an ice volume estimated at 400 cm mean global sea level rise equivalent, are still largely buttressed by ice shelves. LÄS MER
