11. Classification along genre dimensions : exploring a multidisciplinary problem
Sammanfattning : This thesis treats the sociotechnical notion of genre as a conflation of a communicative situation and a community of practices involved in producing and using documents. It explores the ways in which documents may be mapped to the sociocultural contexts from which they emanate. LÄS MER
12. Arctic Ocean benthic foraminifera preservation and Mg/Ca ratios : Implications for bottom water palaeothermometry
Sammanfattning : Reconstructions of Arctic Ocean palaeotemperatures are needed to disentangle natural variability from anthropogenic changes and understand the role of ocean heat transport in forcing or providing feedbacks on Arctic climate change. Despite known complications with calcareous microfossil preservation in Arctic Ocean sediments, calcareous benthic foraminifera can be common in interglacial sequences. LÄS MER
13. Towards a Scenario-based Spatial Dynamic Modeling for Predicting Urban Land Use Change : Planning Tools and Comparative Analysis
Sammanfattning : As global urbanization progresses, cities worldwide are growing in size, which leads to many economic, environmental, and management challenges. Recent advancements in spatial data analysis and algorithmic geography have also led to the development of various urban model-based planning support systems (PSS) for urban planning. LÄS MER
14. Primary Production in African Drylands : Quantifying Supply and Demand Using Earth Observation and Socio-ecological Data
Sammanfattning : The human-environment connection in the mostly rural drylands of sub-Saharan Africa forms a complex, interlinked system that provides ecosystem services. This system is susceptible to climatic variability that impacts the supply of its products, and high population growth, which impacts the demand for these products. LÄS MER
15. Reconstruction of the Southeast Asian hydro-climate using biomarkers and their hydrogen isotopic composition
Sammanfattning : Southeast Asia is characterized by a monsoonal climate, with distinct wet and dry seasons. This has great impact on societies, agriculture and infrastructures. LÄS MER
