    Abstract : Word-finding difficulties, or anomia, are a common symptom in various conditions affecting the brain, such as stroke, multiple sclerosis (MS) or Parkinson’s disease (PD). The aim of this thesis is twofold: (i) to increase our knowledge about the similarities and dissimilarities between the word-finding difficulties associated with different kinds of neurological conditions, and (ii) to evaluate treatment effects of anomia treatment using a method called semantic feature analysis (SFA).

    Abstract : This thesis contributes to the area of research based on large-scale educational assessments, focusing on the application of multilevel models. The role of sampling weights, plausible values (response variable imputed multiple times) and imputation methods are demonstrated by simulations and applications to TIMSS (Trends in International Mathematics and Science Study) and PISA (Programme for International Student Assessment) data.
