1. 1. Testing for Periodicity and Trend in Long-Memory Processes

   Författare :Abdullah Almasri; Statistiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; temperature data.; sunspots data; wind speed data; varve data; Siegel’s test; Fisher’s test; periodogram; Fractional difference process; Discrete wavelet transform; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik; Wavelets; Statistik;

   Sammanfattning : This thesis presents methods of testing the periodicity and trend for the time series, which exhibit dependence over long periods of time. Many such processes can be modeled by a class of models called fractionally differenced processes. LÄS MER

4. 3. Long-term impact of exposure to sulfur mustard on mental health, quality of life, and lung function

   Författare :Faraidoun Moradi; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemical Warfare Agent; Sulfur Mustard; Halabja; Quality of life; Mental health; Small airways dysfunction;

   Sammanfattning : Sulfur mustard is a highly harmful blistering chemical warfare agent with an alkylation ability that can affect multiple organs (skin, eyes and lungs) in the short and long term. Sulfur mustard’s long-term biopsychosocial effects have not been sufficiently studied. LÄS MER

5. 4. Social-ecological dynamics in a highly regulated fisheries system - Sources of resilience and limits to command-and-control management

   Författare :Jonas Hentati-Sundberg; Henrik Österblom; Margit Eero; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; resilience; social-ecological system; feed-backs;

   Sammanfattning : Sustainable governance of natural resources is challenged by the poor understanding of complex human-nature couplings. Major advancements in resilience theory, acknowledging the importance of social-ecological linkages and the self-organizing capacity of social-ecological systems, provides a new perspective on research in sustainability science.

7. 5. The movement towards birth : A study of women's childbirth self-efficacy and early labour

   Författare :Ing-Marie Carlsson; Eva Nissen; Kristina Ziegert; Ann-Kristin Sandin Bojö; Högskolan i Halmstad; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Childbirth self-efficacy; early labour; factor analysis; grounded theory; logistics regression; pregnancy; well-being;

   Sammanfattning : Aim: The overall aim of this thesis was to increase the understanding of early labour, the latency phase of labour, based on women’s experiences and ability to handle the situation. Furthermore, the aim was to perform a psychometric testing of an instrument measuring childbirth self-efficacy and to explore the relationships to women´s well-being and number of obstetric interventions and birth outcomes.
