Production cross section and decay study of $^{243}$Es and $^{249}$Md
2019
In the study of the odd-$Z$, even-$N$ nuclei $^{243}$Es and $^{249}$Md, performed at the University of Jyv\"askyl\"a, the fusion-evaporation reactions $^{197}$Au($^{48}$Ca,2$n$)$^{243}$Es and $^{203}$Tl($^{48}$Ca,2$n$)$^{249}$Md have been used for the first time. Fusion-evaporation residues were selected and detected using the RITU gas-filled separator coupled with the focal-plane spectrometer GREAT. For $^{243}$Es, the recoil decay correlation analysis yielded a half-life of $24 \pm 3$s, and a maximum production cross section of $37 \pm 10$ nb. In the same way, a half-life of $26 \pm 1$ s, an $\alpha$ branching ratio of 75 $\pm$ 5%, and a maximum production cross section of 300 $\pm$ 80 nb…
Transfer reactions in 206Pb+118Sn: From quasielastic to deep-inelastic processes
2023
We measured multinucleon transfer reactions for the 206Pb+118Sn system at Elab=1200 MeV by employing the large solid angle magnetic spectrometer PRISMA. Differential and total cross sections and Q-value distributions have been obtained for a variety of neutron and proton pick-up and stripping channels. The Q-value distributions show how the quasielastic and deep inelastic processes depend on the mass and charge of the transfer products. The corresponding cross sections have been compared with calculations performed with the grazing code. An overall good agreement is found for most of the few nucleon transfer channels. The underestimation of the data for channels involving a large number of …

Exploring the collaborative synthesis of information during online reading
2019
Abstract This descriptive study sought to understand the complexities of integrative processing during collaborative online reading. Student pairs constructed a collaborative understanding while reading online information about a controversial issue by connecting, combining and organizing information that originated from prior knowledge, self-selected online texts, and discussions during an online inquiry task. Thirty-eight students from an upper secondary school in Finland worked in pairs to read online information and write an essay with the help of an argument graph tool. Primary data sources consisted of: prior knowledge; discussions; notes recorded with a graphic representational tool;…
Factors behind Leisure-Time Physical Activity Behavior Based on Finnish Twin Studies: The Role of Genetic and Environmental Influences and the Role o…
2014
Different approaches are being taken to clarify the role of various factors in the development of physical activity behaviors. Genetic studies are a new area of physical activity research and also the motives for physical activity have been widely studied. The purpose of this paper is to review the findings emerging from the longitudinal genetic studies on leisure-time physical activity and to evaluate the associations between motivational factors and leisure-time physical activity. The focus is to review recent findings of longitudinal Finnish twin studies. The results of the latest longitudinal Finnish twin studies point to the existence of age-specific genetic and environmental influence…
Developmental dynamics between young adults’ life satisfaction and engagement with studies and work
2017
The present five-wave longitudinal study investigated the cross-lagged associations between young adults’ life satisfaction and study/work engagement over the transition from post-comprehensive studies to higher education or work during the second and third decades of life. Gender, educational track, academic performance and family socioeconomic status were also examined. The study is part of the longitudinal Finnish Educational Transitions (FinEdu) study, and used data from secondary education onwards, following 821 participants from age 17 to 25. The developmental dynamics showed that, in particular, young adults’ life satisfaction predicted their study/work engagement both during their p…
Postawy wobec globalizacji a satysfakcja z życia. Mediacyjna rola procesów tożsamościowych
2019
The aim of the research was to describe the relationship between attitudes toward globalization and life satisfaction and identity processes in the group of young adults. The sample included of 403 people at the age of 19–35 (M = 22.84, SD = 2.81), 219 women (54.3%) and 184 men. The relations were measured with the use of three questionnaires: Questionnaire of Attitudes Toward Globalization (Senejko, Łoś, 2016), Questionnaire of Identity Formation by A. Oleszkowicz, A. Słowińska (referring to the Dual-Cycle Model of Identity Formation by Luyckx et al., 2006) and SWLS Questionnaire (Diener et. al., 1985). Data analysis was based on structural equation modeling. The research results indicate …
Triggering sustainability communication in a B2B context: combining action research and sensemaking
2021
PurposeThe paper explores processes associated with the adoption of corporate sustainability communication in a B2B context. It employs a combined action research and sensemaking approach to document moments that precede the initiation of external sustainability communication.Design/methodology/approachThe paper is the outcome of an action research project, where we examine the case of one industrial company that was silent on its multiple sustainability-related practices, but recently decided to become more transparent to the outside world. A processual approach to sensemaking is adopted to show how organisational and non-organisational members actively participated in meaning co-construct…
