   Author : Tomasz Pol; Ingmar Persson; Uppsala universitet; []
   Keywords : HUMANIORA; HUMANITIES; Philosophy; moral concepts; the Reconciliation Problem; ethical rationalism; rational requirements; reflective agency; the Aristokantian proposal; generic deontic rules; Filosofi; Philosophy subjects; Filosofiämnen; Practical Philosophy; praktisk filosofi;

   Abstract : The aim of this thesis is to provide an adequate view of moral concepts. The major obstacle that stands in the way of providing such a view is the problem of combining two general features of moral judgments that seem to be constitutive of their meaning, namely objectivity and practical significance.

4. 2. 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

5. 3. There and Back Again - nocturnal migratory behaviour of birds during spring and autumn

   Author : Håkan Karlsson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; migration; seasons; flight; orientation; navigation; behaviour; strategies; birds; nocturnal;

   Abstract : This dissertation explores the migratory behaviour of nocturnally migrating passerines and common swifts (Apus apus). Birds passing Lund (southern Sweden) and Abisko (northernmost Scandinavia) where sampled using tracking radar. The aim has been to investigate potential diverging strategies between spring and autumn migration. READ MORE

6. 4. Evolution of Plants : a mathematical perspective

   Abstract : The Earth harbors around 300 000 plant species. The rich and complex environment provided by plants is considered a key factor for the extraordinary diversity of the terrestrial fauna by, for example, providing food and shelter. READ MORE

7. 5. Avian thermoregulation across age and seasons

   Author : Fredrik Andreasson; Evolutionär ekologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ambient temperature; body temperature; Cyanistes caeruleus; energy expenditure; hypothermia; life-history theory; metabolic rate; Parus major; thermoregulation; trade-off; winter ecology;

   Abstract : Animals constantly need to relate to prevailing environmental conditions and regulate their body temperature accordingly. Body temperature regulation in birds and mammals is inherently linked to energy expenditure and, thus, thermoregulation is a physiological mechanism that could trade-off with other costly processes, with potential long-term fitness consequences.
