  2. 1. Cost efficency of nonresponse rate reduction efforts : an evaluation approach

    Author : Sara Westling; Bengt Swensson; Risto Lehtonen; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonresponse bias; follow-ups; response distribution; resource allocation; cost efficiency; evaluation; nonresponse error; Monte Carlo simulations; Statistics; Statistik; Statistics; Statistik;

    Abstract : Nonresponse, the failure to obtain complete measurement on all sample elements, is an increasing problem in sample surveys. Efforts to reduce the nonresponse rate are expensive and their effect may not be as desired. READ MORE

  4. 2. Methodological aspects on excess cancer riskafter exposure to ionizing radiation

    Author : Erik Holmberg; Göteborgs universitet; []
    Keywords : ionizing radiation; skin haemangioma; breast cancer; parathyroid adenoma; excess cancer risk; bias; confounding; risk models; pooled analysis.;

    Abstract : Aims. The aims of this study were to establish a cohort of persons treated with radiotherapy for skin haemangioma in childhood and study the excess risk of cancer after exposure to ionizing radiation. READ MORE

  5. 3. Processing affective information after sleep loss

    Author : Andreas Gerhardsson; Håkan Fischer; Johanna Schwarz; Daniel Lundqvist; Philippe Peigneux; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sleep deprivation; sleep restriction; affective bias; emotional working memory; positivity effect; sömnbrist; sömnrestriktion; emotionellt bias; arbetsminne; positivitetseffekten; psykologi; Psychology;

    Abstract : It is not fully understood why we need to sleep, although it is evident that sleep loss has consequences for many emotional and cognitive functions. The last couple of decades, sleep researchers have been increasingly devoted to better understand the relationship between sleep and affect. READ MORE

  6. 4. Enhanced Dielectric Response Methods for the Characterization of Dielectric Materials

    Author : Jing Hao; Nathaniel Taylor; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FDS; non-contact; dielectric response; combined AC and DC; space-charge polarization;

    Abstract : Dielectric response measurement is widely used for condition assessment of high voltage equipment and for characterizing candidate materials. Measurement with high accuracy and reliability is important in all stages of the lifetime of high voltage equipment, from manufacture to replacement decision. READ MORE

  7. 5. Development of functional asymmetries in young infants : A sensory-motor approach

    Author : Erik Domellöf; Louise Rönnqvist; Jacqueline Fagard; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Laterality; development; handedness; human infant; stepping response; placing response; head turning; arm movement; reaching; kinematic parameters; intralimb coordination; Psychology; Psykologi;

    Abstract : Human functional laterality, typically involving a right-sided preference in most sensory-motor activities, is still a poorly understood issue. This is perhaps particularly true in terms of what underlying mechanisms that may govern lateral biases, as well as the developmental origins and course of events. READ MORE
