What makes John move? Outdoor play physical environmental factors changing a child’s activity from sedentary to physically active: longitudinal mixed…
2021
Children’s low physical activity levels call for an investigation of what can promote activity for excessively sedentary children. The purpose of this longitudinal mixed-method case study in an early childhood education (ECE) environment was to observe one sedentary child’s free outdoor playtime in four seasons and determine the physical environmental factors changing his activity from sedentary to physically active. Systematic observation of video material and quantitative analysis were used to identify the most sedentary individual of the one ECE group. The child was named “John”. Qualitative analysis of John’s video material showed that during the four seasons he spent an average of 25% …

Obstacles to dialogic encounters between parents and staff in pre-primary school
2020
This study investigate dobstacles to encounters with staff as experienced by parents in the context of institutional pre-primary education in Finland. The study contributes to education research by exploring parents’ perceptions and experiences of encounters with staff from the perspectives of Buber’s (1923/1987; 1947/2002) dialogic philosophy and Giorgi`s (1994) phenomenological psychology. The parent volunteers (n = 15) who participated in planning the local pre-primary education curriculum based on The National Core curriculum for Pre-primary Education 2014 (Finnish National Board of Education 2016) met three times during the 2015–2016 school year in a city in northern Finland. In the la…
Adolf von Beckerin identtiset Ateljeessa-maalaukset – aitoja, kopioita vai väärennöksiä?
2021
Artikkelissa esittelemme kahden Adolf von Beckerin nimiin signeeratun Ateljeessa-teoksen tutkimusta taidehistorian, maalaustekniikan ja materiaalitutkimuksen näkökulmista. Samalla pyrimme tuomaan esiin mitä uutta moniammatillinen yhteistyö ja luonnontieteessä käytetyt menetelmät on tuoneet taideteosten tutkimukseen. Tutkimuksessa voitiin osoittaa, että toinen teoksista on alkuperäinen ja toinen on kopio siitä. Kopion maalaajaksi osoittautui Hilda Granstedt. Tutkimusmenetelminä käytettiin perinteisen arkistotutkimuksen lisäksi erilaisia sähkömagneettista säteilyä tallentavia kuvantamismenetelmiä, kuten röntgen-, ultravioletti- ja infrapunareflektiokuvausta, sekä materiaalianalyyttisiin menet…
I mulini ad acqua: dalla conservazione statica alla pratica sistemica
2013
I mulini di Polizzi: dalla conservazione statica alla pratica sistemica. Il sistema tradizionale di molitura con macine azionate dall'energia idraulica, diffuso in tutto il Mediterraneo, è presente molti Comuni della provincia di Palermo, ed è rimasto in uso fino al secondo dopoguerra. Si tratta di strutture produttive a ruota orizzontale; In genere diversi mulini sorgono in successione lungo lo stesso corso d'acqua, costituendo così un sistema. Sono queste le caratteristiche peculiari della “flomaria molendinorum” nel territorio di Polizzi Generosa: una vera e propria scalinata di impianti idraulici ancora visibili nel paesaggio odierno, concentrazioni testimoniate fin dal XII secolo. All'…
Synergistic effect of W incorporation and pulsed current mode on wear and tribocorrosion resistance of coatings grown by plasma electrolytic oxidatio…
2019
Ceramic coatings were grown by plasma electrolytic oxidation on 7075 Al alloy using unipolar and bipolar pulsed current waveforms with 20 and 40% cathodic duty cycles, from a silicate-based bath without and with the addition of Na2WO4. Pancake-like morphology was dominant on the coatings grown by unipolar waveform, while the bipolar waveforms promoted volcano-like morphology, increased the roughness of the coating surface and the formation of more compact layers. The coatings produced using the bipolar waveforms provided higher resistances toward both tribocorrosion and dry sliding conditions, while further improvement was achieved by the presence of tungsten. The coatings produced in tungs…
Characterization of three-dimensional microstructure of composite materials by X-ray tomography
2016
Analysis methods for X-ray microtomographic images of short fibre composite materials were developed. The methods enable estimation of microstructural properties of the material, e.g., aspect ratio and orientation of fibres. Being based on X-ray microtomography and image analysis, the methods are nondestructive and do not require user intervention. In particular, a method for determination of the aspect ratio of fibres was first developed. The method contains an assumption about similarity of the shape of the fibres. The assumption was relaxed in an improved method that can estimate cross-sectional properties of fibres, too, e.g., cross-sectional area. Additionally, the effect of finite ima…
