On the continuous and discontinuous maximal operators

2018

Abstract In the first part of this paper we study the regularity properties of a wide class of maximal operators. These results are used to show that the spherical maximal operator is continuous W 1 , p ( R n ) ↦ W 1 , p ( R n ) , when p > n n − 1 . Other given applications include fractional maximal operators and maximal singular integrals. On the other hand, we show that the restricted Hardy–Littlewood maximal operator M λ , where the supremum is taken over the cubes with radii greater than λ > 0 , is bounded from L p ( R n ) to W 1 , p ( R n ) but discontinuous.

Country, Sex, and Parent Occupational Status: Moderators of the Continuity of Aggression from Childhood to Adulthood

2014

Using data from two American and one Finnish long-term longitudinal studies, we examined continuity of general aggression from age 8 to physical aggression in early adulthood (age 21–30) and whether continuity of aggression differed by country, sex, and parent occupational status. In all samples, childhood aggression was assessed via peer nominations and early adulthood aggression via self-reports. Multi-group structural equation models revealed significant continuity in aggression in the American samples but not in the Finnish sample. These relations did not differ by sex but did differ by parent occupational status: whereas there was no significant continuity among American children from …

Qui suis-je : Discontinuity as part of teacher identity in Canadian French immersion

2020

The scarcity of research on French immersion teachers’ professional identity contrasts with the increasing popularity of French immersion programs in Canada and the concomitant need for French immersion teachers. This study explores the professional identity negotiation of four French immersion teachers in Alberta, Canada, with a focus on discontinuity. Semi-structured interviews conducted face-to-face with the participants were analysed using dialogic narrative analysis. The findings highlight how discontinuity is occasioned by a change in knowledge about the French immersion teaching as a profession, encountering classroom realities, shifting one’s values concerning second language learni…

Intensity of Aggression in Childhood as a Predictor of Different Forms of Adult Aggression: A Two-Country (Finland and United States) Analysis

2009

This study examined the prediction of different forms of adult aggression in 2 countries from child and adolescent aggression. It was based on 2 longitudinal projects: the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS; N=196 boys and 173 girls) conducted in Finland and the Columbia County Longitudinal Study (CCLS; N=436 boys and 420 girls) conducted in the United States. The same peer‐nominated items for aggression were used in both studies at age 8; comparable measures of aggression were also available in adolescence (age 14 in the JYLS/19 in the CCLS) and adulthood (ages 36/30 and 42/48). Results showed that in both countries and in both genders, aggression in s…

The contribution of public relations to organisational decision making and autopoiesis of organisations : the perspective of the Luhmannian social sy…

2018

This doctoral dissertation investigates the contribution of public relations professionals to organisational decision-making processes and autopoiesis of organisations. The research approach utilises Niklas Luhmann’s functional method approach, regarded as an observational tool to create a distinction between problems and solutions. The research progresses through three parts: Part 1, the preliminary empirical work; Part 2, insights gained from academic articles and reports, and Part 3, empirical work on the perceptions of professionals. This qualitative, content-oriented, interpretive research approach concludes that public relations (PR) is a responsive, managing and adapting function in …

Children’s transitions in early childhood education and care : various combinations of dis-/continuities

2023

This longitudinal multiple case study explores children’s transitions within early childhood education and care (ECEC) in Finland. In ECEC children typically transition from one group or center to another. This study explores how physical, social and philosophical discontinuities and continuities constitute these transitions. Five focus children’s transitions were followed in and between separate ECEC centers. The data include interviews with parents and educators as well as observations noted. Fabian’s discontinuity division, which argues that transition consists of physical, social, and philosophical discontinuities, was used for content analysis of interviews as primary data. Interpretat…
