  2. 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.

  4. 2. Gravure vs. Web-offset! : a changing world in publication printing 1986-2006

    Author : Anders Bjurstedt; Nils Enlund; Robert Chung; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mass communication; Masskommunikation;

    Abstract : The European publication printing industry and its markets have undergone profound structural changes between 1986 and 2006. This thesis is an investigation of these changes and of how the publication industry has been affected, as well as of the balance between publication gravure and commercial heat-set web-offset.

  5. 3. Stellar kinematics in surveys and simulations

    Author : Daniel Mikkola; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Galactic dynamics; stellar dynamics; simulations; Gaia; Galactic dynamics; Stellar kinematics; Numerical simulations; Statistical methods; Solar neighborhood;

    Abstract : We study stellar motions in the Milky Way with N-body simulations and large astrometric samples from ESA's Gaia mission. We identify two kinematic populations for white dwarfs in the Solar neighbourhood. We also investigate the accreted halo and reveal two new structures. READ MORE

  6. 4. On the cost-efficiency of probability sampling based mail surveys with a web response option

    Author : Peter Werner; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : Web surveys - the collection of survey data by means of self-administered questionnaires on the Internet - are becoming increasingly popular, perhaps mostly because of advantageous cost factors. If e-mail contacts are used, the cost benefit of a Web survey, compared with a mail or telephone survey, could be major. READ MORE

  7. 5. Harm from others’ drinking : reported negative experiences and predictors in general population surveys

    Author : Erica Sundin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Alcohol consumption is among the top risk factors for ill health and premature death and can also lead to a range of problems in relation to other people such as family members, friends, co-workers, and among strangers in public places. Research into harm from other people’s drinking has increased substantially in the last decade and has developed into a separate research field. READ MORE
