  1. 1. Uniformella förhandlingar : Hierarkier och genusrelationer i Postens kläder 1636-2008

    Författare :Marianne Larsson; Birgitta Svensson; Lisa Öberg; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; civilian uniform; steering mechanisms; hierarchy; classification; gender; identity; masculinity; negotiations; disciplinary power; cultural history; clothes; Post Office; Ethnology; Etnologi; Ethnology; etnologi;

    Sammanfattning : The postal uniform represents a state authority while simultaneously clothing the body of an individual. Via discussions about breakpoints, events, and negotiations, the study highlights cultural and social patterns in civilian uniform practice. A basic theme is how society classifies and hierarchizes people, above all, masculinity, via uniform. LÄS MER

  3. 2. Exploring mechanisms of peer effects in education : Frame factor analyses of classroom instruction

    Författare :Pontus Bäckström; Jesper Boesen; Charlotta Mellander; Jan-Eric Gustafsson; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Despite a vast international literature, previous research into compositional effects and peer effects in education has remarked on the lack of consensus within the field. To date, peer effects in education and students’ different opportunities to learn in school have been studied separately. LÄS MER

  4. 3. Neural mechanisms for the control of posture, locomotion and steering : a behavioral, electrophysiological and modeling study in lamprey

    Författare :Patriq Fagerstedt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :reticulospinal; vestibular system; spinal cord; central pattern generator; reciprocal inhibition; fictive locomotion; fictive turning; electron microscopy; computer simulation; lamprey; dorsal fin;

    Sammanfattning : When animals move around interacting with the environment, the nervous system has to solve several tasks simultaneously in order to produce and control the movements - notably propulsion, posture, balance, and associated movements. Basic motor tasks are controlled by neuronal networks organized into central pattern generators (CPGs) and reflexes, located in the spinal cord and brainstem. LÄS MER

  5. 4. Molecular mechanisms of human mitochondrial dynamics : inspiration and challenge

    Författare :Rong Yu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mitochondria are highly dynamic organelles in cells. They frequently change the morphology via continuous fission and fusion events, referred to as mitochondrial dynamics, which includes the shape, size and number of mitochondria in the cell, as well as mitochondrial subcellular distribution and mitochondrial quality control.

  7. 5. Neural mechanisms for the visual control of spatial orientation and locomotion : electrophysiological and behavioural studies of the supraspinal control of posture and steering in the lamprey central nervous system, with reference to visuo-motor mechanisms

    Författare :Fredrik Ullén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neural mechanisms for the supraspinal control of posture and steering, in particular visuo-motor control and visuo-vestibular interaction in postural control, were investigated, using the lamprey as a model system. Behavioural experiments on intact and chronically lesioned animals, intra- and extracellular recordings in vitro and retrograde staining of neurons with horseradish peroxidase were utilized. LÄS MER
