1. 1. Pedagogisk forskning i Sverige 1948-1971 : en explorativ studie av inom- och utomvetenskapliga faktorer

   Författare :Gerd Lindberg; Leif Lindberg; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; History of behavioral sciences; history of educational research; paradigm analysis; science and society;

   Sammanfattning : The purpose of this work has been to shed light on the science of education, primarily in the period 1948-1971. The work also consists of the establishment of education as an academic discipline (1910-1948). The theoretical frame of reference is Kuhn's theory about the structure of scientific revolutions.

3. 2. Stress Coping Strategies in Brown Trout (Salmo Trutta): Ecological Significance and Effects of Sea-Ranching

   Författare :Daniel Brelin; Svante Winberg; Erik Petersson; Jörgen Johnsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoophysiology; Stress-coping-strategies; Animal-personalities; Behavioral-syndromes; Brown trout; Salmo trutta; Catecholamines; Sexual maturation; Hatchery; Phenotype; Learning; Zoofysiologi; Biology; Biologi;

   Sammanfattning : Two distinct stress coping strategies, proactive and reactive, have been stated in various animal studies, each associated with a set of behavioural and physiological characteristics. In a given challenging situation, proactive animals show more aggression, a higher general activity and a predominant sympathetic reaction. LÄS MER

4. 3. Species Limits, and Evolutionary History of Glassfrogs

   Författare :Santiago Castroviejo-Fisher; Carles Vilà; Jennifer A. Leonard; Miguel Vences; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amphibia; Anura; Biogeography; Centrolenidae; Diversification; Frogs; Molecular Phylogenetics; Neotropics; Pristimantis; Speciation; Species; Systematics; Taxonomy; Systematics and phylogenetics; Systematik och fylogeni; systematisk zoologi; Systematic Zoology;

   Sammanfattning : Recognizing the mechanisms of speciation and the limits of species is essential to understand the origin of biodiversity and how to conserve it. The general aims of my investigations during my doctoral studies were two-fold: to study evolutionary patterns and processes, and to provide specific and superspecific taxonomic classifications that try to reflect evolutionary history.

5. 4. LIVING WITH PARASITES: AVIAN MALARIA, TELOMERE LENGTH AND LIFE HISTORY TRADE-OFFS

   Författare :Asghar Muhammad; MEMEG; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Avian malaria; Plasmodium; qPCR; parasitemia; life history; reproduction; survival; feather growth; MHC; telomere length; heritability; telomere loss; fitness; wild population; Acrocephalus arundinaceus; Delichon urbica;

   Sammanfattning : Haemosporidia is a well-studied group of parasites, which infect mammals, reptiles and birds and use blood sucking vectors for their transmission. By conducting natural population studies and experimental infections, We have been able to detect and quantify Haemosporidia from avian blood to investigate how these pathogens affect their avian hosts.

7. 5. Insomnia: psychological mechanisms and early intervention : a cognitive-behavioral perspective

   Författare :Markus Jansson; Steven J. Linton; Lars-Gunnar Lundh; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; insomnia; development; distress; worry; early intervention; cognitive-behavioral therapy; dysfunctional beliefs and attitudes about sleep; Psykologi; Psychology; Psykologi; Psychology; Psykologi;

   Sammanfattning : This dissertation focused on the role of psychological mechanisms in the development of insomnia and the effectiveness of an early cognitive-behavioral intervention for insomnia. The first aim was to examine whether distress, worry, and dysfunctional beliefs and attitudes about sleep were related to the development of insomnia. LÄS MER
