3. 2. Investigating and Validating Spoken Interactional Competence: Rater Perspectives on a Swedish National Test of English

   Författare :Linda Borger; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; interactional competence; Swedish national test of English; paired speaking test; Common European Framework of Reference for Languages CEFR ; socio-cognitive validation framework;

   Sammanfattning : This thesis aims to explore different aspects of validity evidence from the raters’ perspective in relation to a paired speaking test, part of a high-stakes national test of English as a Foreign Language (EFL) in the Swedish upper secondary school. Three empirical studies were undertaken with the purpose of highlighting (1) the scoring process, (2) the construct underlying the test format, and (3) the setting and test administration. LÄS MER

4. 3. On Rank-invariant Methods for Ordinal Data

   Författare :Yishen Yang; Sune Karlsson; Elisabeth Svensson; Rolf Larsson; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ordinal data; rank-invariance; systematic change; agreement; association; inter-rater reliability; ranking; Spearman; multi-item scale; Statistik; Statistics;

   Sammanfattning : Data from rating scale assessments have rank-invariant properties only, which means that the data represent an ordering, but lack of standardized magnitude, inter-categorical distances, and linearity. Even though the judgments often are coded by natural numbers they are not really metric. LÄS MER

5. 4. Quantifying neurodegeneration from medical images with machine learning and graph theory

   Författare :Gustav Mårtensson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Neurodegeneration (or brain atrophy) is part of the pathological cascade of Alzheimer’s disease (AD) and is strongly associated with cognitive decline. In clinics, atrophy is measured through visual assessments of specific brain regions on medical images according to established rating scales. LÄS MER

7. 5. Dermal exposure determinants : a pesticide exposure assessment approach for developing countries

   Författare :Luis E Blanco Romero; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Dermal exposure; pesticides; determinants of dermal exposure to pesticides; subsistence farmers; fluorescent tracer; visual scoring system;

   Sammanfattning : Background: We know little about the levels of exposure to pesticide in subsistence farmers mainly because of lack of easy to use and low cost pesticide exposure assessment methods. Aim: This thesis aimed to develop a semi-quantitative approach to assess dermal exposure to pesticides relevant for conditions in developing countries. LÄS MER
