Lifelong physical activity and long-term labor market outcomes
2018
This thesis examines the longitudinal associations between leisure-time physical activity, educational attainment, and labor market outcomes. Data are drawn from the ongoing longitudinal Cardiovascular Risk in Young Finns Study, which is combined with register-based data from Statistics Finland. The thesis consists of four empirical studies organized in separate chapters. The study chapters are preceded by an introductory chapter presenting the background literature and an overview of the thesis, including the research questions, data, and main results. Chapter 2 analyzes the role of childhood physical activity in academic achievement and subsequent educational attainment. We find that phys…
Disrupting neural activity related to awake-state sharp wave-ripple complexes prevents hippocampal learning
2012
Oscillations in hippocampal local-field potentials (LFPs) reflect the crucial involvement of the hippocampus in memory trace formation: theta (4–8 Hz) oscillations and ripples (~200 Hz) occurring during sharp waves are thought to mediate encoding and consolidation, respectively. During sharp wave-ripple complexes (SPW-Rs), hippocampal cell firing closely follows the pattern that took place during the initial experience, most likely reflecting replay of that event. Disrupting hippocampal ripples using electrical stimulation either during training in awake animals or during sleep after training retards spatial learning. Here, adult rabbits were trained in trace eyeblink conditioning, a hippoc…
Individual Creativity and Career Choices of Pre-teens in the Context of a Math-Art Learning Event
2021
A sample of 392 students (aged 12-13 years, M± SD: 12. 52% girls) completed a learning module integrating informal hands-on mathematics and arts activity (extending STEM to STEAM). Within a 140 minute workshop period participants worked with commercially available ‘4Dframe’ Math and STEAM learning toolkits to design and create original, personal and individual geometrical structures. Two science pedagogues acted as tutors supervising the process and intervened only when needed. A pre-/post-test design monitored individual creativity, relative autonomy, and career choice preference. Path analysis elaborated the role of creativity (measured with two subscales: act and flow), and it showed tha…
Lähijohtaminen kestävän oppimisen edistäjänä työelämässä (JoKo): Tutkimushankkeen loppuraportti
2023
Luet Työsuojelurahaston rahoittaman JoKo-hankkeen (Lähijohtaminen kestävän oppimisen edistäjänä työelämässä) loppuraporttia. Tuomme tässä raportissa esille havaintojamme hankkeen aikana kerätyn haastatteluaineiston annista ja toteutetun ryhmävalmennuksen kokemuksista ja luomme niiden pohjalta syvempää ymmärrystä oppimisen kestävyydestä työssä. Suomalaisessa työelämässä painotetaan osaamisen ja jatkuvan oppimisen merkitystä erityisesti asiantuntijatyössä, mutta ymmärrystä oppimisen kestävyydestä meillä on vielä hyvin vähän. Tutkimusta hyvinvointia lisäävän eli kestävän oppimisen tukemisesta ja johtamisesta meillä on vielä vähemmän. Tällainen ymmärrys on kuitenkin ensiarvoisen tärkeää huomioi…
Physical activity measured by accelerometry among adolescents participating in sports clubs and non-participating peers
2022
The purpose of this descriptive cross-sectional study is to describe the amount and intensity of physical activity (PA) measured by accelerometry among adolescents participating in organized sports (SCP) and age-matched non-participating peers (NP). SCPs (332) and NPs (139) wore an accelerometer on the hip for seven days. PA was reported using the 1-min exponential moving average. The current moderate-to-vigorous physical activity (MVPA) recommendation of at least an average of 60 min of MVPA daily was reached by 85% of SCPs and 45% of NPs (p < .001). During training days, the MVPA times among SCPs ranged from 153 ± 39 min in males and 109 ± 35 min in females participating in basketball to …
Leisure-time physical activity and participation in organized sports : changes from 1985-2014 in Finland and Norway
2019
Participation in organized sports is a popular and important part of the lives of children and adolescents and is associated with improved psychological and social health, as well as an increased likelihood of meeting physical activity (PA) recommendations. Changes in modern society, including increased car ownership and use of technology and electronic media, have led to an additional focus on the importance of health‐enhancing PA among children and adolescents. The aim of this article was to study the secular changes in self‐reports of participation in organized sports clubs and leisure‐time vigorous physical activity (LVPA), and whether the relationship between participation in organized…
Kavereiden tuen yhteys lasten ja nuorten liikunta-aktiivisuuteen ja seuraharrastamiseen
2017
Tämän pro gradu -tutkielman tarkoituksena oli selvittää kavereiden yhteyttä lasten ja nuorten liikunta-aktiivisuuteen ja urheiluseurassa harrastamiseen. Tutkielmassa tarkasteltiin viides-, seitsemäs- ja yhdeksäsluokkalaisten lasten ja nuorten liikuntakäyttäytymistä sekä sitä, millainen yhteys heidän kavereillaan siihen oli. Tutkimus perustui maaliskuussa 2016 kerättyyn valtakunnallisen LIITU-tutkimuksen aineistoon. LIITU-tutkimuksen aineisto kerättiin sähköisellä kyselylomakkeella ja vastaajia oli yhteensä 5586. Vastaajista 1989 oli viidesluokkalaisia, 1948 seitsemäsluokkalaisia ja 1649 yhdeksäsluokkalaisia. Aineisto analysoitiin ristiintaulukoinnilla, khiin neliötestillä (χ²) sekä yksisuun…

Outdoor activities and motor development in 2–7-year-old boys and girls
2021
Problem Statement: Parents of young children favor indoor activities for their children, because staying inside supports comfortable daily routines in the family timetable, safety issues and clothing. However, playing outdoors supports children’s development, offering multiple challenges to overcome and the possibility to learn new skills. Approach: Based on Gibson’s theory of affordances (1977), outdoors can be seen as an excellent learning environment for children to reach the zone of proximal development (Vygotsky, 1987). Purpose: This paper describes Finnish nature and four seasons as an environment to support children’s motor development and inspire outdoor playing. The Skilled kids pa…
Synthesis of Amino-1,2,4-triazoles by Reductive ANRORC Rearrangements of 1,2,4-Oxadiazoles
2010
The reaction of various 1,2,4-oxadiazoles with an excess of hydrazine in DMF has been investigated. 3-Amino- 1,2,4-triazoles are produced through a reductive ANRORC pathway consisting of the addition of hydrazine to the 1,2,4-oxadiazole followed by ring-opening, ring-closure, and final reduction of the 3-hydroxylamino-1,2,4-triazole intermediate. The general applicability of 1,2,4-oxadiazoles ANRORC reactivity is demonstrated also in the absence of C(5)-linked electron-withdrawing groups.
