    Sammanfattning : In this thesis, I used the color polymorphic pygmy grasshopper, Tetrix subulata, as a model system in order to investigate the degree of niche differentiation between alternative color morphs that are present within a single population. First, I hypothesized that individuals belonging to different color morphs differ in their innate food preference due to somewhat dissimilar physiology, and in their actual food consumption due in part to differential habitat use.

    Sammanfattning : Research regarding the aesthetic features of wood and people's preferences for different appearances of wood has to date been rather limited. Today it is common to use computers to show how a room or product will look when or if it is produced. LÄS MER

  4. 3. Psychosocially supportive design in the indoor environment

    Författare :Geza Fischl; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Psychology; Teknisk psykologi;

    Sammanfattning : A built environment is psychosocially supportive, when its quality can strengthen or sustain the ability of an individual to perform his/her role, conduct him-/herself in society, and communicate or interact with others in accordance to his/her values, interest, and self-concept. The aim of this thesis was to investigate potential methods in design and re-design for identification, visualization, and evaluation of such environmental qualities. LÄS MER
