Itsejärjestäytyvä DNA-kultananopartikkeli-rakenne yhden elektronin transistorina
2012
Tässä tutkielmassa selvitettiin kultananopartikkelien ja itsejärjestäytyvän DNA-järjestelmän soveltuvuutta nanoteknologian komponenttina. Työssä yhdistetään funktionalisoituja kultapartikkeleita jo valmiiksi tutkittuun itsejärjestäytyvään DNA-rakenteeseen työnimeltään BAB. Se muodostuu kolmen TX-tiilen ketjusta, johon suunnittelin kandidaatin tutkinnossani kiinnityskohdat kultapartikkeleille. Yhdistämällä kultapartikkelit ja BAB-rakenne saadaan muodostettua kolmen partikkelin ketju, ja tällä rakenteella pyritään muodostamaan yhden elektronin transistori: Toiminta yhden elektronin transistorina pyrittiin havainnoimaan Coulombin saarron avulla mittaamalla differentiaalista konduktanssia sekä …

Participatory research methods with young children : a systematic literature review
2023
This systematic literature review aimed to ascertain what participatory methods for young children have been used in peer-reviewed empirical articles. A systematic literature search yielded 75 articles. Based on their methodology, the studies were divided into six categories: (1) multi-method and the Mosaic approach, (2) observation and ethnography, (3) language-based methods, (4) visual methods, (5) creative and playful methods, and (6) children as co-researchers. The participatory features of these methods were then analyzed. The articles foregrounded the importance of the reflective use of methods, ethically grounded research practices, and carefully considering young children’s particip…
Child–educator disagreements in Finnish early childhood education and care: young children’s possibilities for influence
2022
This study explores young children’s possibilities for influence in situations of child–educator disagreement in Finnish early childhood education and care (ECEC). Data were gathered from observations conducted in four ECEC groups of under three year-olds. A total of 112 child–educator disagreements were analysed qualitatively using reflexive thematic analysis. Children’s influence was rather limited in most disagreements, as these involved the established institutional order as manifested in the rules and norms of daily activities and educators’ control over children’s bodies and material resources. However, disagreements over social rules and the ongoing social situation often allowed chi…
Pienten lasten osallisuus vuorohoidon iltojen vuorovaikutustilanteissa
2021
Tutkimuksessa tarkastellaan, kuinka pienten lasten osallisuus toteutuu vuorohoidon iltojen vuorovaikutustilanteissa ja millaisia haasteita tähän liittyy. Aineisto kerättiin havainnoimalla 20–36 kk ikäisten lasten iltoja kahdessa erilaisessa vuoropäiväkodissa. Temaattisen analyysin perustana toimivat Lundyn (2007) kuvaamat, Yhdistyneiden Kansakuntien (YK) lapsen oikeuksien sopimuksen artiklaan 12 pohjautuvat lasten osallisuuden edellytykset. Huomion kohteena olivat erityisesti työntekijöiden toiminta ja sen lapsille luomat mahdollisuudet ilmaista mielipiteitään sekä tulla kuulluksi ja huomioiduksi. Muuttuva iltaryhmä sekä päiväkodin rutiinit ja säännöt rajoittivat toisinaan lasten osallisuud…
Changes in the Use Intention of Digital Wellness Technologies and Its Antecedents Over Time : The Use of Physical Activity Logger Applications Among …
2021
Physical inactivity has become a prevalent problem among elderly people. Although digital wellness technologies have been proposed as one promising solution to it, our understanding on the antecedents of the acceptance and use of these technologies among elderly people remains limited. In this study, our objective is to promote this understanding by examining the potential changes in the use intention of digital wellness technologies and its antecedents over time in the case of the young elderly segment and physical activity logger applications. We base this examination theoretically on UTAUT2 and empirically on survey data that is collected from 99 Finnish young elderly users of a physical…
A Follow-Up On The Changes in the Changes in the Use Intention of Digital Wellness Technologies and Its Antecedents Over Time : The Use of Physical A…
2021
This study aims to further promote the understanding of the antecedents of the acceptance and use of digital wellness technologies among elderly people through a follow-up to our two prior studies, one which examines the potential longer-term temporal changes in the use intention of digital wellness technologies and its antecedents in the case of the young elderly segment and physical activity logger applications. We base this examination theoretically on UTAUT2 and empirically on survey data that is collected from 92 Finnish young elderly users of a physical activity logger application in three subsequent time points and analysed with partial least squares structural equation modelling (PL…
Applying UTAUT2 to Explain the Use of Physical Activity Logger Applications Among Young Elderly
2020
Digital wellness technologies have been proposed as a promising way to promote the levels of physical activity and to solve the prevalent problem of physical inactivity among elderly people. In this study, we propose and test a research model for explaining the acceptance and use of these technologies in the case of the young elderly segment (people aged 60–75 years) and physical activity logger applications. The proposed model is theoretically founded on UTAUT2, and it is empirically tested by using the data collected from 115 Finnish young elderly users of a physical activity logger application and analysed with partial least squares based structural equation modelling (PLS-SEM). We find …
Physical activity change and stability patterns from adolescence to early adulthood : how activity domains and sedentary behaviour are associated wit…
2022
Background Longitudinal studies demonstrate that physical activity (PA) declines on average from adolescence to early adulthood. However, some subgroups of adolescents increase activity while others decrease or maintain high or low activity. Determinants of change or maintenance of (in)activity may differ between subgroups and are valuable information for targeted health promotion. The purpose of this study was to identify PA patterns from adolescence to early adulthood, and also to explore how different activity domains and Sedentary Behaviour (SB) are associated with PA patterns. Methods The data of this observational cohort study (collected in 2013/2014 and 2017/2018) consisted of 254 Fi…
Hierarkiat yläkoulun kaveriporukoissa : nuoren kokema sosiaalinen asema ja liikkuminen
2021
The low level of physical activity among young people has become a common societal concern. This study sought new information on the backgrounds of adolescents’ physical activity. The aim was to find out whether the adolescents’ subjective social status is related to physical activity. The data were collected as part of the follow-up research and evaluation of the Finnish Schools on the Move programme in 2012–2015. The data were collected through student surveys, measuring adolescents’ physical activity with accelerometers, and observing and interviewing secondary school students. The associations between adolescents’ subjective social status and physical activity, as well as the factors re…
