Depression and Violence in Adolescence and Young Adults: Findings From Three Longitudinal Cohorts
2017
Objective Despite recent research demonstrating associations between violence and depression in adults, links in adolescents are uncertain. This study aims to assess the longitudinal associations between young people’s depression and later violent outcomes. Method We used data from three cohorts with different measurements of depression exposures and subsequent violent outcomes. In a Dutch community cohort Research on Adolescent Development And Relationships (RADAR; N = 623) and a population-based British birth cohort Avon Longitudinal Study of Parents and Children (ALSPAC; N = 4,030), we examined the longitudinal links between adolescent depressive symptoms and violent behaviors from age 1…

Learning research in a laboratory classroom : a reflection on complementarity and commensurability among multiple analytical accounts
2022
With the myriad theories generated through research over the years, a continuing challenge for researchers is to navigate the multitude of theories in order to communicate their research, integrate empirical results, and make progress as a field by building upon empirical research. The Social Unit of Learning project was purposefully designed so that researchers from multiple disciplines with different theoretical perspectives could work together to examine the complexity of the mathematics classroom. In this paper, we reflect on the multiple analytical accounts generated from the project, drawing from the notions of complementarity and commensurability. Two parallel analyses, applying the …
Mathematics Learning through Arts and Collaborative Problem-Solving : The Princess and the Diamond-Problem
2016
In this paper, we examine a mathematics education course which focused on collaborative mathematical problem solving in art topics. The students of the course were Finnish primary school pre-service teachers. During the course students investigated tessellations, reflected on their experiences and designed workshops for pupils. The course meetings were video recorded. Students’ work contained elements of mathematical problem solving and gave them experiences of working collaboratively. The topic of tessellation was found suitable for this purpose. peerReviewed

Pētījumā izmantotas metodes: •teorētiskā metode - literatūras analīze, •empīriskās metodes - pedagoģiskā novērošana, statistiskā datu apstr…
Teacher Guidance in Mathematical Problem-Solving Lessons : Insights from Two Professional Development Programs
2019
When implementing a problem-solving lesson, the teacher needs to provide students appropriate guidance during problem solving. This demanding task requires understanding students’ work in progress and giving them necessary help without constraining their thinking. In this article, we share insights from two professional development programs on how teachers guided students’ problem solving and how they reflected on these instances. One of the programs included Finnish pre-service teachers, while the other program included US in-service teachers. We analyzed video-recorded problem-solving lessons from 16 Finnish and 2 US teachers in grades 6–9. We found two themes about teacher guidance of st…
What drives increases in hindsight impressions after the reception of biased media content?
2021
Prior research has shown that reading biased media content (e.g., Wikipedia articles) can increase recipients' hindsight bias. It remained unclear, however, which features of the biased texts led to such an increase. We examined this question in a longitudinal experimental study (N = 190). Specifically, we tested whether repeated exposure to already known information (H₁), a more coherent presentation of the information (H₂), or the presentation of novel information (H₃) affected readers' hindsight impressions of likelihood, inevitability, and foreseeability. To this end, participants initially learned about an event by reading several short news, and, 1 week later, received one of several …
Unawareness, Priors and Posteriors
2008
Abstract. This note contains first thoughts on awareness of unawareness in a simple dynamic context where a decision situation is repeated over time. The main consequence of increasing awareness is that the model the decision maker uses, and the prior which it contains, becomes richer over time. The decision maker is prepared to this change, and we show that if a projection-consistency axiom is satisfied unawareness does not affect the value of her estimate of a payoff-relevant conditional probability (although it may weaken confidence in such estimate). Probability-zero events however pose a challenge to this axiom, and if that fails, even estimate values will be different if the decision …
Analysis of a viscoelastic phase separation model
2020
A new model for viscoelastic phase separation is proposed, based on a systematically derived conservative two-fluid model. Dissipative effects are included by phenomenological viscoelastic terms. By construction, the model is consistent with the second law of thermodynamics, and we study well-posedness of the model, i.e., existence of weak solutions, a weak-strong uniqueness principle, and stability with respect to perturbations, which are proven by means of relative energy estimates. A good qualitative agreement with mesoscopic simulations is observed in numerical tests.
