2. 1. Understanding Individuals' Learning and Decision Processes in a Changing Environment by Using Panel Data

   Author : Nursitihazlin Ahmad Termida; Yusak Susilo; Joel Franklin; Kiron Chatterjee; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Behavioural responses; seasons; panel data; travel diary; activity-travel pattern; theory of planned behaviour; space-time constraint; changing environment; tram; Stockholm; Transportvetenskap; Transport Science;

   Abstract : When a new transport service is introduced, people have to learn and familiarize themselves with the new service before they decide to adopt it. These processes are developed over time, thus produce dynamics in individuals’ behavioural responses towards the service. This affects the demand of the new service, thus affect revenues. READ MORE

4. 2. A Changing Experience : communication and meaning-making in web-based teacher training

   Author : Linda Reneland-Forsman; Per Gerrevall; Monica E Nilsson; Elsebeth Korsgaard Sorensen; Växjö universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; course design; higher education pedagogy; mediated discourse analysis; meaning-making; mediation; teacher training; web-based learning; web-based teaching; widened participation; Education; Pedagogik; Pedagogik; Pedagogics;

   Abstract : This is a study of students’ meaning making in web-based higher education courses. Conditions for students meaning-making change when interaction technology is used to support educational practices. Widened Participation policy activities often use web-based programs to attract “new” groups of more experienced students. READ MORE

5. 3. Peatland Bryophytes in a Changing Environment : Ecophysiological Traits and Ecosystem Function

   Author : Gustaf Granath; Håkan Rydin; Joachim Strengbom; Steven K Rice; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; allometric scaling; chlorophyll fluorescence; competition; decomposition; flooding; mire; N concentration; nitrogen deposition; photosynthesis; succession; stoichiometry; Ecological Botany; Ekologisk botanik;

   Abstract : Peatlands are peat forming ecosystems in which not fully decomposed plant material builds up the soil. The sequestration of carbon into peat is mainly associated with the bryophyte genus Sphagnum (peat mosses), which dominate and literally form most peatlands. READ MORE

6. 4. Baltic Sea phytoplankton in a changing environment

   Author : Mireia Bertos-Fortis; Catherine Legrand; Ilana Berman-Frank; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; phytoplankton ecology; cyanobacteria; dynamics; environmental factors; successional patterns; interactions; life strategies; non-ribosomal peptides; diversity; nodularin; N. spumigena; Akvatisk ekologi; Aquatic Ecology;

   Abstract : Future climate scenarios in the Baltic Sea project increasing sea surface temperature, as well as increasing precipitation and river runoff resulting in decreased salinity. These changes can severely impact the dynamics and function of brackish water communities, specifically phytoplankton. READ MORE

7. 5. Life history decisions in a changing environment : A long-term study of a temperate barnacle goose population

   Author : Henk van der Jeugd; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Age at first reproduction; Barnacle goose; Branta leucopsis; Coloniality; Dispersal; Life-history; Mate choice; Population dynamics; Survival; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Animal Ecology; zooekologi;

   Abstract : This thesis shows that climate and increasing population density have profound effects on survival, age at first reproduction, and natal dispersal in a rapidly increasing temperate barnacle goose Branta leucopsis population on Gotland, Sweden.Colony size was found to be the most important fitness-determinant because of strong density-dependent effects on reproduction.
