Studying Gamow-Teller transitions and the assignment of isomeric and ground states at $N=50$
2022
Direct mass measurements of neutron-deficient nuclides around the N=50 shell closure below $^{100}$Sn were performed at the FRS Ion Catcher (FRS-IC) at GSI, Germany. The nuclei were produced by projectile fragmentation of $^{124}$Xe, separated in the fragment separator FRS and delivered to the FRS-IC. The masses of 14 ground states and two isomers were measured with relative mass uncertainties down to 1×10−7 using the multiple-reflection time-of-flight mass spectrometer of the FRS-IC, including the first direct mass measurements of $^{98}$Cd and $^{97}$Rh. A new QEC=5437±67 keV was obtained for $^{98}$Cd, resulting in a summed Gamow-Teller (GT) strength for the five observed transitions (0+…
Direct measurement of the mass difference of $^{72}$As-$^{72}$Ge rules out $^{72}$As as a promising $\beta$-decay candidate to determine the neutrino…
2021
We report the first direct determination of the ground-state to ground-state electron-capture $Q$-value for the $^{72}$As to $^{72}$Ge decay by measuring their atomic mass difference utilizing the double Penning trap mass spectrometer, JYFLTRAP. The $Q$-value was measured to be 4343.596(75)~keV, which is more than a 50-fold improvement in precision compared to the value in the most recent Atomic Mass Evaluation 2020. Furthermore, the new $Q$-value was found to be 12.4(40)~keV (3.1 $\sigma$) lower. With the significant reduction of the uncertainty of the ground-state to ground-state $Q$-value value combined with the level scheme of $^{72}$Ge from $\gamma$-ray spectroscopy, we confirm that th…
Real-Time Processes of Career Goal Construction : A Study Case Approach with Implications for the Development of Adolescents’ Identity
2022
The study aimed at investigating how different young people going through the post-high school transition set, monitor, pursue, and renegotiate career goals in real-time and in everyday life circumstances. A theoretically driven proposition supported the conceptualization of career goals as complex dynamic systems and guided the examination and description of the moment-to-moment processes shaping the (re)construction of career goals. The study adopted an exploratory research approach and was based on a longitudinal case study design. Diary reports were collected for 39 weeks. Participants were four young people (three females, one male) who at the onset of the study were 18 years of age an…
Preparing for working life : effects of group counseling on adolescents' career development and mental health

The role of mothers' beliefs in students' self-concept of ability development
2018
The aim of this study was to investigate whether the child-related competence beliefs of mothers are associated with the development of Finnish adolescents' self-concept of mathematics and literacy ability during their transition from primary to lower secondary school and whether these associations depend on adolescents' level of performance. The results showed that, first, adolescents' self-concept of mathematics and literacy ability decreased over time. The impact of maternal beliefs on the linear trend of the self-concept of mathematics and literacy ability was dependent on the level of students' performance. Mothers' high beliefs buffered against the decrease in adolescents' self-concep…
New Metropolitan Perspectives Transition with Resilience for Evolutionary Development
2023
This open access book conveys attention to the theme of transition towards resilience and sustainability and its evolutionary perspective that emphasizes the complexity and uncertainty that governments and society are called to address in response to the ongoing challenges. "New Metropolitan Perspective Post COVID Dynamics: Green and Digital Transition, between Metropolitan and Return to Villages’ Perspectives”, 25–27 May 2022, Reggio Calabria, Italy. The papers included in the book are grouped around the following main topics: the envisaged transition towards resilience and sustainability; the relevance of the planning dimension for defining sustainable development pathways and managing co…
Sedentary Patterns and Sit-to-Stand Transitions in Open Learning Spaces and Conventional Classrooms among Primary School Students
2022
Educational reforms worldwide have resulted in schools increasingly incorporating open and flexible classroom designs that may provide possibilities to reduce sedentary behavior among students during lessons. Cross-sectional associations of classroom type on accelerometry assessed sedentary bout durations and sit-to-stand transitions were investigated in 191 third and fifth grade students recruited from one school with open learning spaces and two schools with conventional classrooms. A three-way ANOVA for classroom type, gender and grade level indicated that students in open learning spaces had more 1-to-4-min sedentary bouts (mean difference 1.8 bouts/h, p 10-min sedentary bouts (median 0…
Development of Participation in and Identification With School: Associations With Truancy
2020
This longitudinal study covering two educational transitions examined 1,821 Finnish students’ participation in and identification with school and their associations with students’ academic achievement and truancy. The students were surveyed (a) at the end of primary school, (b) at the beginning of lower secondary school, (c) at the end of lower secondary school, and (d) in the first year of upper secondary education. In alignment with the participation-identification model, higher levels of participation in school activities at the end of primary school predicted higher levels of identification (i.e., feelings of belonging and valuing school) at the end of lower secondary school. This asso…
Externalizing behaviour and academic performance – the cross-lagged relationship during school transition
2017
The current study examined the over-time association between externalizing behaviour problems and academic performance during school transition in a cross-lagged design. The main focus was to revea...
Students' Positive Expectations and Concerns Prior to the School Transition to Lower Secondary School
2020
This mixed-method study examines students' expectations and concerns before transitioning from primary to lower secondary school and the role of students' school-related wellbeing and self-esteem in their concerns. Students reported their beliefs about the forthcoming school transition and filled in a questionnaire assessing school burnout and self-esteem. The results showed that the students had positive expectations comprising comfort, friendships, learning, school environment, increased freedom and teacher -student relations. The students' concerns were mainly related to friendships. Furthermore, results indicated that students who reported concerns about peer relations were likely to ex…
