Enhancing Digital Skills of Early Childhood Teachers Through Online Science, Technology, Engineering, Art, Math Training Programs in Estonia
2022
Teacher professional development programs, including mid- and long-term Science, Technology, Engineering, Art, Math (STEAM) courses, have recently moved from in person learning at university premises to an online environment. Whether it is a temporary change in learning methods caused by the COVID-19 restrictions or whether it will become a new normal is currently under discussion in many teacher training institutions around the world. The aim of this study was to design and implement time- and money-saving synchronous online teacher training format for conducting co-design courses for early childhood teachers in the theme of STEAM integrated learning activities. Based on Tallinn University…
SWOT-analyysin soveltaminen yrityksen kyberturvallisuuden tilannekuvan muodostamiseen : Cyber Trust/CIRP-raportti : tutkimusmenetelmän kuvaus 2017
2018
Modernin yhteiskunnan toiminta perustuu useiden kriittisten infrastruktuurien yhteistoimintaan. Niiden keskinäinen toimintakyky riippuu yhä enemmän luottamuksesta infrastruktuuriin kuuluvien organisaatioiden toimintakykyyn kybertoimintaympäristössä, jonka riskejä digitaalisen maailman uhkakuvat jatkuvasti kasvattavat. SWOT-analyysi on tärkeä väline analysoitaessa organisaation toimintakykyä ja sen toimintaympäristöä kokonaisuutena. Se on nelikenttämenetelmä, jota käytetään yleisesti tilannekuvan muodostamiseen laadittaessa yrityksen strategioita, sekä oppimisen tai ongelmien tunnistamisessa, arvioinnissa ja toimintaprosessien kehittämisessä. SWOTanalyysin kohteena voi olla jonkin yrityksen …
Päätöspuiden käyttö koneoppimisessa
2017
Päätöspuihin perustuvia menetelmiä ollaan käytetty laajasti koneoppimisen eri tehtävissä. Tämä tutkielma kokoaa tietoa siitä miten ja mihin näitä menetelmiä ollaan käytetty. Käydään läpi yksittäisen päätöspuun luominen datasta ja tämän pohjalta tutustutaan kokoonpanomenetelmiin, joissa kootaan useita päätöspuita. Lopulta tutustutaan vielä joihinkin esiteltyjen menetelmien sovelluksiin. Methods based on decision trees have been utilized widely in different tasks of machine learning. This study compiles information on how and for what purposes have these methods been used. Construction of a decision tree based on data is explained and with that as a basis ensemble methods, which comprise many…
The development of secondary students’ feedback literacy: Peer assessment as an intervention
2020
A growing body of research has recognized the importance of students’ having active roles in feedback processes. Feedback literacy refers to students’ understandings of and participation in feedback processes, and research on students’ feedback literacy has so far focused on higher education; secondary schools have not received attention. This case study investigates secondary students’ feedback literacy and its development in the context of formative peer assessment. From various data sources, three categories of students’ feedback literacy were identified, and criteria for the levels of literacy in each category were created. The criteria were used in the coding of seventh- and eighth-gra…
Rasch Analysis of the Japanese Version of Teacher Efficacy for Inclusive Practices Scale: Scale Unidimensionality
2020
This study aimed to examine the construct validity of the Japanese version of the Teacher Efficacy for Inclusive Practices (TEIP) scale. The sample consisted of 250 teachers in Japan. Rasch analysis was used to examine the psychometric properties of the scale. Results did not support the 18-item Japanese version of the TEIP scale as a unidimensional scale for measuring TEIP. However, they do support the final 14-item Japanese version of the TEIP scale as a unidimensional scale for measuring TEIP. Four items were removed from the original 18-item scale (items 12, 8, 5, and 3) for violation of the local independency assumption. No item with differential item functioning (DIF) was detected. On…
Frame analysis of psychotherapists’ perspectives on the development of psychological disorders
2021
AbstractThe development of psychological disorders has been explained by several psychological theories and remains under debate. Psychotherapists, however, have insights into the emergence and development of psychological disorders that stem from both theory and practice. The constantly evolving field of psychotherapy prompts reconsideration, specifically when psychotherapists’ views on the development of disorders impacts their treatment approach. In addition, theoretical orientation and years of clinical experience, while known to influence psychotherapists’ viewpoints also merit further study. Applying Erving Goffman’s frame analysis, semi structured interviews with psychotherapists wer…
Disentangling conditional effects of multiple regime shifts on Atlantic cod productivity
2020
AbstractRegime shifts are increasingly prevalent in the ecological literature. However, definitions vary, and many detection methods are subjective. Here, we employ an operationally objective means of identifying regime shifts, using a Bayesian online change-point detection algorithm able to simultaneously identify shifts in the mean and(or) variance of time series data. We detected multiple regime shifts in long-term (59-154 years) patterns of coastal Norwegian Atlantic cod (>70% decline) and putative drivers of cod productivity: North Atlantic Oscillation (NAO); sea-surface temperature; zooplankton abundance; fishing mortality (F). The consequences of an environmental or climate-relate…
Effect of macro and micro nutrients addition during anaerobic mono-digestion of grass silage in leach-bed reactors
2019
The effect of macro- (NH4Cl) (set I) and micro-nutrients (Fe, Ni, Co and Mo) (set II) addition on chemical oxygen demand (COD) solubilisation during anaerobic mono-digestion of grass silage was investigated in two sets of leach bed reactor experiments at 35°C. Results showed that addition of NH4Cl and micro-nutrients improved COD solubilisation by 18% (0.56 g SCOD g−1 volatile solids) and 7% (0.45 g SCOD g−1 VS), respectively than control. About 20–50% of the added micro-nutrients were bioavailable in the produced leachates, while the rest (50–80%) were adsorbed onto the grass silage. Results of biological methane potential assays showed that, specific methane yields of grass silage were im…
Radiation Hardness Assurance Through System-Level Testing: Risk Acceptance, Facility Requirements, Test Methodology, and Data Exploitation
2021
International audience; Functional verification schemes at a level different from component-level testing are emerging as a cost-effective tool for those space systems for which the risk associated with a lower level of assurance can be accepted. Despite the promising potential, system-level radiation testing can be applied to the functional verification of systems under restricted intrinsic boundaries. Most of them are related to the use of hadrons as opposed to heavy ions. Hadrons are preferred for the irradiation of any bulky system, in general, because of their deeper penetration capabilities. General guidelines about the test preparation and procedure for a high-level radiation test ar…
Predictors of school students’ leisure-time physical activity : An extended trans-contextual model using Bayesian path analysis
2021
Abstract Background:The trans-contextual model (TCM) has been applied to identify the determinants of leisure-time physical activity participation in secondary school students. In the current study, the TCM was extended to include additional constructs that represent non-conscious, implicit processes that lead to leisure-time physical activity participation alongside the motivational and social cognition constructs from the TCM. The current study used baseline and follow-up data from an intervention study to test the extended TCM.Methods:The current study adopted a two-wave prospective design. Secondary-school students (N = 502) completed measures of perceived autonomy support from physical…
