Field conversations as a data source in qualitative social research
2020
Sammendrag Denne artikkelen belyser feltsamtaler som forskningsverktøy. Feltsamtaler er ofte usynlige og underkommunisert i den vitenskapelige litteraturen. Samtalene lar seg vanskelig tallfeste og beskrive; de mangler tilsynelatende systematikk og framstår gjerne bare som hverdagslig prat. Med søkelys på konteksten for samtalen og samtalens rammer og regi setter artikkelen feltsamtalen inn et kvalitativt metodeunivers. Feltsamtalen plasserer vi i et kontinuum mellom det kvalitative intervjuet på den ene siden og alminnelig prat mellom forsker og informant på den andre. Ved hjelp av eksempler fra vår egen empiriske forskning diskuterer vi feltsamtalenes bidrag som datainnsamlingsverktøy. Vi…
Modeling of intracellular transport in realistic cell geometries
2018
The transport of molecules inside cells is a complex process, the characterization of which is important to gain full understanding of cellular processes. Understanding of intracellular transport is also important for medical applications, for example when analyzing transport of medicine inside cells. The intracellular environment is very complex, and at least the most crucial parts of this complexity must be accounted for to solve transport problems in cells. In this thesis the results of studies in modeling intracellular transport are presented. The aim of the work was to model intracellular transport of proteins and viral capsids in realistic cell environments. To this end, microscopic m…
Reproducibility of irritant patch test reactions to sodium lauryl sulfate in a double-blind placebo-controlled randomized study using clinical scorin…
1999
Reading of doubtful patch test reactions can be improved by comparing them to defined negative, allergic and irritant controls. For the latter, an irritant patch test is needed that gives sufficiently reproducible results. In our double-blind, placebo-controlled. randomized study, we have analysed the synchronous reproducibility of patch tests with 0%, 0.0625%, 0.125%, 0.25%, 0.5% and 1.0% sodium lauryl sulfate (SLS). Tests and readings were done according to ESCD guidelines. 139 patients (75 women, 64 men) 18 to 77 years old were tested. The % of positive patients as well as the % of reproducible positive reactions increased with rising concentrations of SLS to a maximum of approximately 9…
A Marching in Space and Time (MAST) solver of the shallow water equations. Part I: The 1D model
2007
A new approach is presented for the numerical solution of the complete 1D Saint-Venant equations. At each time step, the governing system of Partial Differential Equations (PDEs) is split, using a fractional time step methodology, into a convective prediction system and a diffusive correction system. Convective prediction system is further split into a convective prediction and a convective correction system, according to a specified approximated potential. If a scalar exact potential of the flow field exists, correction vanishes and the solution of the convective correction system is the same solution of the prediction system. Both convective prediction and correction systems are shown to …
Guaranteed error bounds for linear algebra problems and a class of Picard-Lindelöf iteration methods
2012
This study focuses on iteration methods based on the Banach fixed point theorem and a posteriori error estimates of Ostrowski. Their application for systems of linear simultaneous equations, bounded linear operators, as well as integral and differential equations is considered. The study presents a new version of the Picard–Lindelöf method for ordinary differential equations (ODEs) supplied with guaranteed and explicitly computable upper bounds of the approximation error. The estimates derived in the thesis take into account interpolation and integration errors and, therefore, provide objective information on the accuracy of computed approximations.

Integrating Self-Reports and Electrodermal Activity (EDA) Measurement in Studying Emotions in Professional Learning
2022
Studies on emotions in learning have been mostly conducted through self-reporting questionnaires and interviews conducted after the learning situation, which seldom focus on professional workplace learning. Meanwhile, workplace and professional learning research has been introduced with emerging methods to capture the learning processes at multiple levels. Previous research on emotions has suggested that self-reports should be supplemented with psychophysiological data. Challenged by this, this chapter aims to present and discuss the integration of self-reported and psychophysiological data in studying emotions and professional learning. The empirical research data are obtained from five Fi…
The role of daily autonomous and controlled educational goals in students’ academic emotion states: An experience sampling method approach
2018
The present study examines antecedents of university students' academic emotions (Pekrun, Goetz, Titz, & Perry, 2002) in the context of self-determination theory (SDT; Deci & Ryan, 1985; 2000), using realtime assessment and intra-individual analyses. We investigated whether daily autonomous and controlled-motivated educational goals predicted students' academic emotions. University students (N = 55) completed smartphone diaries over 14 consecutive days. The two-week intensive longitudinal data were organized in a hierarchical three-level structure, with situations (Level 1) nested within days (Level 2) nested within students (Level 3). Students' goal motivation was assessed in morning quest…
Iedomu valodas: H.F. Lavkrafta grāmatas “Kthulhu aicinājums” un tās latviskā tulkojuma analīze
2020
Izdomu valodas ir paredzētas būt par neatliekamu un visai svarīgu daļu izdomu pasaulēm daiļliteratūrā (un ne tikai), un ir bieži izgudrotas ar nolūku padarīt izdomu pasaules ticamākas. Daudzi slaveni rakstnieki jau senos laikos ir iepazīstinājuši daiļliteratūras lasītājus ar savām izdomu valodām. Šis maģistra darbs ir par Hovarda Filipsa Lavkrafta izdomu valodu “R’lje”, kura pastāv viņa pat izdomātā pasaulē ar nosaukumu “Cthulhu Mythos”. Šo valodu var sastapt vairākās grāmatās, filmā un arī videospēlē, bet šis maģistra darbs būs vairāk koncentrēts uz to valodu, kura sastopama tikai grāmatās un videospēlē. Šajā pētījumā es analizēju Lavkrafta grāmatu “Kthulhu aicinājums”, izvērtēju šīs grāma…
La economía social como enfoque metodológico, como objeto de estudio y como disciplina científica
1999
This article continues an article written by the same author and published by CIRIEC-España in 1997 (no. 25). It analyses social economy at three cognitive levels: first, as a social reality (Social Economy); second, as a scientific discipline which studies its previous reality (the science of Social Economy); third, as a methodological approach in social sciences (the approach of Social Economy). The author claims that, at these three levels, social economy becomes an alternative way of “making the economy”.
