  1. 1. Leaving Home in a Peasant Society. Economic Fluctuations, Household Dynamics and Youth Migration in Southern Sweden, 1829-1866

    Author : Martin Dribe; Ekonomisk-historiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic history; historical demography; economic stress; migration; family strategy; longitudinal analysis; leaving home; event-history analysis; Ekonomisk och social historia;

    Abstract : This study deals with the process of children leaving home and its interactions with the household economy in preindustrial society. A theoretical model of leaving home is outlined and then analyzed multivariately, using a longitudinal micro-level dataset for a sample of parishes in western Scania, Sweden, for the period 1829-1866.

  2. 2. Optimal strategies and information in foraging theory

    Author : Emma Sernland; Högskolan i Skövde; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bayesian foraging; information use; public information; prior information; negative binomial distribution; group foraging; decision-making; information updating; leaving strategy; Ecology; Ekologi; NATURAL SCIENCES; NATURVETENSKAP; Other biology; Övrig biologi; Naturvetenskap; Natural sciences; information use;

    Abstract : In this thesis, I present both theoretical and empirical work where we have studied how humans and animals use information in situations where they need to continually update their information on the density of a resource. We have found that the amount of information, and the way the information is presented, are important factors for how well decisions are adapted to current circumstances. READ MORE

  3. 3. Clinical translation of a regeneration strategy for spinal cord injury

    Author : Arvid Frostell; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : The complex and vulnerable tissue of the spinal cord does not heal after injury, leaving patients with lifelong disability after spinal cord injury (SCI). Many milestones have been reached during the last century through specialized centers for SCI, greatly increasing life expectancy and quality of life by battling common medical problems such as urinary tract infections, pressure ulcers, spasticity, neurogenic pain, and sexual function as well as providing means of rehabilitation to a meaningful and productive life after SCI.

    Abstract : This thesis deals with the design of 18F- and 68Ga-labelled positron emission tomography (PET) tracers and the development of technologies that enable faster and simpler preparation with high specific radioactivity. Techniques like microwave heating and reducing the concentrations of the precursor were investigated with this perspective. READ MORE
