    Sammanfattning : This thesis consists of four research papers presenting a microdata analysis approach to assess and evaluate the Parkinson’s disease (PD) motor symptoms using smartphone-based systems. PD is a progressive neurological disorder that is characterized by motor symptoms. LÄS MER

  5. 4. The physical classroom environment : roles, conceptions, and preferences

    Författare :Magnus Fahlström; Högskolan Dalarna; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys; Mikrodataanalys; Microdata Analysis;

    Sammanfattning : The problem addressed in this thesis is that a considerable proportion of students around the world attend school in inadequate facilities, which is detrimental for the students’ learning outcome. The overall objective in this thesis is to develop a methodology, with a novel approach to involve teachers, to generate a valuable basis for decisions regarding design and improvement of physical school environment, based on the expressed needs for a specific school, municipality, or district as well as evidence from existing research.

  7. 5. Nonresponse issues when analysing business survey data

    Författare :Åsa Grek; Mark Dougherty; Martin Johanson; Fredrik Hartwig; Lars Hultkrantz; Högskolan Dalarna; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys; Mikrodataanalys; Microdata Analysis;

    Sammanfattning : Data issues due to nonresponse or missing data arises often in company surveys or in firm data. Missing data and nonresponse causes bias. Another problem that causes bias is omitted variables. Accordingly, it will lead to wrong conclusions. LÄS MER
