  1. 1. Two Topics in Survey Methodology : Inference from Nonprobability Samples Using the Double Samples Setup

    Author : Boris Lorenc; Daniel Thorburn; Lars Lyberg; Gösta Forsman; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; response process; establishment surveys; socially distributed cognition; response burden; measurement error; nonprobability samples; web surveys; double samples; propensity scores; model-based estimation; imputation; nonparametric imputation; weighting; Surveying; Lantmäteri;

    Abstract : Modelling the response process in establishment surveys proceeded thus far by adding steps of operational character to the core cognitive steps of the individual cognitive model. Here (Paper 1) a larger unit of the cognitive analysis is posited: that part of the enterprise that is engaged in responding to a survey, consisting of one or more employees, the tools they use and the established practices of record keeping and survey responding.

  2. 2. Surviving Birth and Thriving : Identifying infants at risk of death and disability in low- and middle-income countries

    Author : Antti Kukka; Ashish KC; Helena Litorp; Nick Brown; Thorkild Tylleskär; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pediatrics; neonatology; physiology; neonatal encephalopathy; hypoxia-ischemia; heart rate; neonatal resuscitation; neonatal follow-up; disabiltiy; cerebral palsy; general movements assessment; global health; low- and middle-income countries; pilot projects; telemedicine; qualitative research; Pediatrik; Pediatrics;

    Abstract : Background: Ending preventable newborn deaths is an unfinished global health agenda. Infants surviving birth have a right to thrive and to reach their full developmental potential. READ MORE

  3. 3. Rock Mechanical Consequences of Refrigeration. A Study Based on a Pilot Scale Rock Cavern

    Author : Lars-Olof Dahlström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; temperature decrease; tensile strength; thermomechanical loading; compressive strength; Poisson s ratio; thermal contraction; rock caverns; rock mass deformation; Young s modulus;

    Abstract : The deformation of a rock mass due to temperature decrease below freezing is very complex, since many factors are involved; thermal strain, strain due to stress change, stress re-distribution, ice formation and the temperature dependency of rock mechanical and thermo-physical properties. The objective of this study was to achieve a better understanding of the rock mass response to thermo-mechanical loading when storing low temperature products in rock caverns excavated in hard crystalline rock masses.

  4. 4. 3D Time-lapse Analysis of Seismic Reflection Data to Characterize the Reservoir at the Ketzin CO2 Storage Pilot Site

    Author : Fei Huang; Christopher Juhlin; Alireza Malehmir; Ari Tryggvason; Andy Chadwick; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2 storage; 3D Time-lapse 4D ; Reservoir characterization; Seismic simulation; Spectral decomposition; Wavelet phase; Tuning frequency; Thin-layer thickness; Seismic monitoring; Seismic processing; Quantitative interpretation; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : 3D time-lapse seismics, also known as 4D seismics, have great potential for monitoring the migration of CO2 at underground storage sites. This thesis focuses on time-lapse analysis of 3D seismic reflection data acquired at the Ketzin CO2 geological storage site in order to improve understanding of the reservoir and how CO2 migrates within it.

  5. 5. Att läsa : -ett behov, -ett krav, -en nödvändighet : en analys av den första internationellt jämförande studien av vuxnas förmåga att förstå och använda skriftlig information :  International Adult Literacy Survey = [Reading] : [-a need, a requirement, a necessity]

    Author : Anna-Lena Eriksson-Gustavsson; Linköpings universitet; []
    Keywords : IALS; international comparative study; adults reading ability; adults reading habits; education; reading diaries; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : This is a presentation and an analysis of the International Adult Literacy Survey, IALS, the first international comparative study of reading ability and reading habits among adults. The study was carried out in seven countries in Europe and North America during 1994 och 1995. READ MORE
