Investigating applicability of ratings of indicators of the CLASS Pre-K instrument
2022
When classroom observations are increasingly used for accountability and evaluation purposes, a deeper understanding of the psychometric properties of such measurement tools is needed. The present study took a unique approach to examine the psychometric properties of a commonly used classroom observation measure by testing the reliability of indicators for higher-order constructs (i.e. dimensions). We investigated the reliability of indicator ratings of the Classroom Assessment Scoring System (CLASS) Pre-K instrument in Finnish kindergarten and first grade classrooms. Twenty-one observer pairs rated 838 segments identified from the 413 lessons of 48 teachers. Variance components models were…
Uutisia ranteessa? : älykellojen soveltuvuus journalismiin. Loppuraportti
2016
Tämän tutkimushankkeen päätarkoituksena oli selvittää älykellojen soveltuvuus journalismiin, sen uutena sisällönjulkaisupaikkana sekä työvälineenä. Keskeisinä tiedonhankinnan menetelminä olivat journalistisen ja tutkimuksellisen aineiston jatkuva monitorointi, asiantuntijahaastattelut (N=6) sekä älykellojen testaus koeryhmien avulla. Vähintään kuukauden mittaisen testijakson teki yhteensä yhdeksän testaajaa. Tutkimuksen keskeisenä tuloksena oli, että älykellot eivät ole ainakaan vielä vuonna 2016 nousseet uudeksi varteenotettavaksi viestinnän laitekategoriaksi eivätkä ne siten ole korvaamassa esimerkiksi älypuhelimia. Suurin hyöty älykelloista on breaking news -uutistilanteissa, jolloin uut…
Estimation of forest stand characteristics using individual tree detection, stochastic geometry and a sequential spatial point process model
2022
Airborne Laser Scanning (ALS) results in point-wise measurements of canopy height, which can further be used for Individual Tree Detection (ITD). However, ITD cannot find all trees because small trees can hide below larger tree crowns. Here we discuss methods where the plot totals and means of tree-level characteristics are estimated in such context. The starting point is a previously presented Horvitz–Thompson-like (HT-like) estimator, where the detectability is based on the larger tree crowns and a tuning parameter that models the detection condition. We propose a new method which is based on modeling the spatial pattern of hidden tree locations using a sequential spatial point process mo…
New β-decaying state in 214Bi
2021
A new β-decaying state in 214Bi has been identified at the ISOLDE Decay Station at the CERN-ISOLDE facility. A preferred Iπ = (8−) assignment was suggested for this state based on the β-decay feeding pattern to levels in 214Po and shell-model calculations. The half-life of the Iπ = (8−) state was deduced to be T1/2 = 9.39(10) min. The deexcitation of the levels populated in 214Po by the β decay of this state was investigated via γ -γ coincidences and a number of new levels and transitions was identified. Shell-model calculations for excited states in 214Bi and 214Po were performed using two different effective interactions: the H208 and the modified Kuo-Herling particle interaction. Both ca…
First β-decay spectroscopy of $^{135}$In and new $β$-decay branches of $^{134}$In
2021
International audience; The $\beta$ decay of the neutron-rich $^{134}$In and $^{135}$In was investigated experimentally in order to provide new insights into the nuclear structure of the tin isotopes with magic proton number $Z=50$ above the $N=82$ shell. The $\beta$-delayed $\gamma$-ray spectroscopy measurement was performed at the ISOLDE facility at CERN, where indium isotopes were selectively laser-ionized and on-line mass separated. Three $\beta$-decay branches of $^{134}$In were established, two of which were observed for the first time. Population of neutron-unbound states decaying via $\gamma$ rays was identified in the two daughter nuclei of $^{134}$In, $^{134}$Sn and $^{133}$Sn, at…
Inactivity is an independent health risk : objectively measured muscle activity and inactivity during normal daily life of ordinary people
2011
Pesola, Arto 2011. Inactivity is an independent health risk: objectively measured muscle activity and inactivity during normal daily life of ordinary people. Master’s thesis in exercise physiology. Department of Biology of Physical Activity, University of Jyväskylä. 96 pages. Today’s society promotes oversitting, and physical inactivity appears to be an independent health risk. The continuum from total inactivity to vigorous intensity training contains different physiological actions and objective measurements are needed to find out associations between physical activity, inactivity and health. The purpose of this study was to describe muscle activity and inactivity during normal daily life…
Validity of long-term and short-term recall of occupational sitting time in Finnish and Chinese office workers
2020
Background As sedentary behavior is a global health issue, there is a need for methods of self-reported sitting assessment. The accuracy and reliability of these methods should also be tested in various populations and different cultural contexts. This study examined the validity of long-term and short-term recall of occupational sitting time in Finnish and Chinese subgroups. Methods Two cohort groups of office-based workers (58.6% female, age range 22–67 years) participated: a Finnish group (FIN, n = 34) and a Chinese group (CHI, n = 36). Long-term (past 3-month sitting) and short-term (daily sitting assessed on 5 consecutive days) single-item measures were used to assess self-reported occ…
Company values guiding the recruitment of employees with a foreign background
2019
Purpose In this paper, the following research question is addressed: Why do business organisations recruit employees with a foreign background? This was examined in terms of the values that guide organisations and their management. The paper aims to discuss this issue. Design/methodology/approach The study focused on two businesses in Finland that are pioneers in the recruitment of immigrants. A case study approach was adopted. The research data consist of interviews and documentary data. The data were analysed using content analysis in accordance with grounded theory. Findings Companies can act as an enabling force in the integration of immigrants into the local labour market, especially …
