On the thermal instability in a horizontal rectangular porous channel heated from below by a constant flux
(Journal article; Peer reviewed, 2014)The onset of thermoconvective instability in a rectangular horizontal channel filled with a fluid-saturated porous medium is studied. The channel is heated from below with a constant flux. The top wall is maintained at a ... -
Online mathematics teaching and learning during the COVID-19 pandemic: The perspective of lecturers and students
(Peer reviewed; Journal article, 2021)The global spread of the novel coronavirus, Covid-19, reached Norway at the end of February 2020. MatRIC, Centre for Research, Innovation and Coordination of Mathematics Teaching conducted a national survey in Norwegian ... -
Onset of convection in a porous rectangular channel with external heat transfer to upper and lower fluid environments
(Journal article; Peer reviewed, 2012)The conditions for the onset of convection in a horizontal rectangular channel filled with a fluid saturated porous medium are studied. The vertical sidewalls are assumed to be impermeable and adiabatic. The horizontal ... -
Onset of Convection in an Inclined Anisotropic Porous Layer with Internal Heat Generation
(Peer reviewed; Journal article, 2019)The onset of convection in an inclined porous layer which is heated internally by a uniform distribution of heat sources is considered. We investigate the combined effects of inclination, anisotropy and internal heat ... -
Oscillation criteria for even-order neutral differential equations

Oscillation of fourth-order quasilinear differential equations
(Journal article; Peer reviewed, 2015) -
Oscillation of second-order neutral differential equations
(Journal article; Peer reviewed, 2013)We study oscillatory behavior of a class of second-order neutral differential equations relating oscillation of these equations to existence of positive solutions to associated first-order functional differential inequalities. ... -
Oscillation results for second-order nonlinear neutral differential equations
(Journal article; Peer reviewed, 2013)We obtain several oscillation criteria for a class of second-order nonlinear neutral differential equations. New theorems extend a number of related results reported in the literature and can be used in cases where known ... -
Oscillation theorems for second-order nonlinear neutral delay differential equations
(Journal article; Peer reviewed, 2014)We analyze the oscillatory behavior of solutions to a class of second-order nonlinear neutral delay differential equations. Our theorems improve a number of related results reported in the literature. -
Oscillatory behavior of second-order nonlinear neutral differential equations
(Journal article; Peer reviewed, 2014)We study oscillatory behavior of solutions to a class of second-order nonlinear neutral differential equations under the assumptions that allow applications to differential equations with delayed and advanced arguments. ... -
Pedagogical criteria for successful use of wikis as collaborative writing tools in teacher education
(Journal article; Peer reviewed, 2012)Wiki is a Web 2.0 technology that potentially promotes collaborative writing, group discussion and interaction. However, little research has been done as to which criteria are suitable to address pedagogical issues that ... -
Persecution and Patronage: Oscar Buneman’s years in Britain

Perspectives and reflections on teaching linear algebra
(Peer reviewed; Journal article, 2020)This paper presents ‘expert opinions’ on what should be taught in a first-year linear algebra course at university; the aim is to gain a generic picture and general guiding principles for such a course. Drawing on a Delphi ... -

(Journal article; Peer reviewed, 2018) -
Pre-Service Teachers’ Self-efficacy as Future Mathematics Teachers in a Second Language Classroom
(Journal article; Peer reviewed, 2023)This study contributes to the field of research on teacher self-efficacy by investigating a group of multilingual pre-service teachers’ perceptions of self-efficacy in Norwegian mathematics classrooms. In recent years, ... -
Premeditated automaticity: the role of explicit cognition in the development of obsessive smoking
(Journal article, 2010)Abstract The purpose of the present study was to examine the role of explicit cognitions in relation to the development of obsessive smoking passion. Data derives from a longitudinal internet survey conducted among 939 ... -
Professional mathematics teacher identity: analysis of reflective narratives from discourses and activities
(Journal article; Peer reviewed, 2012)This article focuses on the methodological use of reflective narratives from discourses and activities of an experienced primary teacher as evidence of her professional identity. The teacher’s reflective narratives emerge ... -
Project-based learning in a computer modelling course
(Peer reviewed; Journal article, 2021) -
Proof by induction – the role of the induction basis
(Journal article; Peer reviewed, 2018) -
Prospective mathematics teachers? self-referential metaphors as indicators of the emerging professional identity
(Peer reviewed; Journal article, 2019)Ideals play a key role in a student teachers’ identity work. They form targets to strive for and a mirror for reflection. In this paper, we examine Finnish mathematics student teachers’ metaphors for the teacher’s role ...
