1. 1. The Heterogeneity of Behavior in Operations Processes : Empirical Evidence

   Författare :Neslihan Özlü; Fredrik Eng Larsson; Thomas Hartman; Olov Isaksson; Kai Hoberg; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; behavioral operations; empirical operations; heterogeneity; experience effects; ordering decisions; choice models; judgmental forecasting; operations processes; Business Administration; företagsekonomi;

   Sammanfattning : Behavioral science research has established that observed human behavior may deviate considerably from model suggestions. In addition to the realization that there is no such thing as standardized human behavior, there are also substantial differences in how people deviate from the model: Different individuals make dissimilar decisions in the same situation when using the same information.

3. 2. Quality Management in Hospital Departments : Empirical Studies of Organisational Models

   Författare :Stefan Kunkel; Ragnar Westerling; Urban Rosenqvist; Lars Borgquist; Uppsala universitet; []
   Nyckelord :Social medicine; Quality Management; Organisational Models; Hospital Departments; Socialmedicin;

   Sammanfattning : The general aim of this thesis was to empirically explore the organisational characteristics of quality systems of hospital departments, to develop and empirically test models for the organisation and implementation of quality systems, and to discuss the clinical implications of the findings. Data were collected from hospital departments through interviews (n=19) and a nation-wide survey (n=386). LÄS MER

4. 3. Models and meaning : on management models and systems of meaning when implementing change

   Författare :Jacob Hallencreutz; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

   Sammanfattning : Change has become a vital business partner for many organizations. Survival of most organizations depends on their ability to implement adequate changes to support the organization. This thesis deals with questions about measurement systems, process based system models and organizational change with a specific focus on implementation challenges. LÄS MER

5. 4. Latent variable models for longitudinal twin data

   Författare :Annica Dominicus; Juni Palmgren; Nancy L. Pedersen; Michael G. Kenward; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Latent variable models; twin models; variance components; change point models; non-ignorable nonresponse; likelihood ratio tests; Mathematical statistics; Matematisk statistik;

   Sammanfattning : Longitudinal twin data provide important information for exploring sources of variation in human traits. In statistical models for twin data, unobserved genetic and environmental factors influencing the trait are represented by latent variables. In this way, trait variation can be decomposed into genetic and environmental components. LÄS MER

7. 5. Probabilistic Sequence Models with Speech and Language Applications

   Författare :Gustav Eje Henter; W. Bastiaan Kleijn; Arne Leijon; Gernot Kubin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time series; acoustic modelling; speech synthesis; stochastic processes; causal-state splitting reconstruction; robust causal states; pattern discovery; Markov models; HMMs; nonparametric models; Gaussian processes; Gaussian process dynamical models; nonlinear Kalman filters; information theory; minimum entropy rate simplification; kernel density estimation; time-series bootstrap;

   Sammanfattning : Series data, sequences of measured values, are ubiquitous. Whenever observations are made along a path in space or time, a data sequence results. To comprehend nature and shape it to our will, or to make informed decisions based on what we know, we need methods to make sense of such data. LÄS MER
