Ultraviolet B radiation induced alterations in immune function of fish : in relation to habitat preference and disease resistance
2009
Runsas altistuminen auringolle on tunnetusti haitallista ihmisten ja eläinten hyvinvoinnille. Eveliina Markkula tutki väitöskirjatyössään, miten ultravioletti B (UVB) -säteilylle altistuminen vaikuttaa kalojen vastustuskykyyn ja tautialttiuteen.- Ilmakehän otsonikerroksen oheneminen viime vuosikymmenten aikana on johtanut UVB-säteilyn lisääntymiseen maan pinnalla. UVB-säteily tunkeutuu myös kirkkaisiin järvi- ja merivesiin ja voi näin aiheuttaa haittaa kaloille, Markkula kertoo.UVB-säteilyn on jo aiemmin todettu lisäävän kalojen varhaisten elinvaiheiden epämuodostumia ja kuolleisuutta. Kertaluonteinenkin altistuminen lampuilla tuotetulle UVB-säteilylle aiheuttaa muutoksia kalan immuunijärje…
Wzajemne oddziaływanie norm prawa upadłościowego i restrukturyzacyjnego oraz norm prawa podatkowego w procesie ich tworzenia i stosowania – wstęp do …
2021
Problematyka istnienia norm różnych dziedzin prawa, które wzajemnie na siebie oddziaływają, nie jest zjawiskiem nowym. Niemniej w przypadku gdy stosowanie jednych z nich wyklucza inne normy prawa bądź też prowadzi do osłabienia ich oddziaływania, jest to sytuacja niepożądana. Dotyczy to zarówno jednostki, jak i organów władzy publicznej. Normy prawa upadłościowego i restrukturyzacyjnego nie zawsze uwzględniają specyfikę prawa podatkowego – i odwrotnie. W rezultacie w trudnych z natury postępowaniach upadłościowych i restrukturyzacyjnych pojawiają się dodatkowo niełatwe zagadnienia podatkowe, co stwarza niepotrzebne ryzyko w działaniach stron, organów i sądów. Wymaga to dodatkowej wiedzy, cz…
Sensitivity of bipartite network analyses to incomplete sampling and taxonomic uncertainty
2023
Bipartite network analysis is a powerful tool to study the processes structuring interactions in ecological communities. In applying the method, it is assumed that the sampled interactions provide an accurate representation of the actual community. However, acquiring a representative sample may be difficult as not all species are equally abundant or easily identifiable. Two potential sampling issues can compromise the conclusions of bipartite network analyses: failure to capture the full range of interactions (sampling completeness) and use of a taxonomic level higher than species to evaluate the network (taxonomic resolution). We asked how commonly used descriptors of bipartite antagonisti…
Scaffolding teachers to foster inclusive pedagogy and presence through collaborative action research
2017
Teachers can be influential change agents in transforming their schools if they regularly reflect on their pedagogical practices, looking for improvements that will help all learners reach their fu...
Quality of educational dialogue and association with students’ academic performance
2018
The study used a mixed-methods approach to examine the associations between the quality of educational dialogue and students' academic performance and to analyse what kinds of dialogic teaching patterns of different levels of quality can be identified in classroom lessons. A total of 158 Grade 6 lessons were video-recorded, and the quality of the educational dialogue was assessed using the Classroom Assessment Scoring System-Secondary (CLASS-S) observational instrument. Multilevel modelling indicated that the quality of educational dialogue was positively associated with students’ academic performance (grades) in language arts and physics/chemistry. Qualitative analysis was subsequently use…
"Teachers teach so well that it's nice to learn" : a case-study on the role of teacher-to-student feedback in attitude-formation on L2 elementary Eng…
2015
Arviointi ja palautteenanto ovat oleellisia asioita opettajan jokapäiväisessä työssä. Lisäksi asenteiden tutkiminen on tällä hetkellä suosittu tutkimusala. Tässä tapaustutkimuksessa tutkittiin, millaista vuorovaikutuksellista palautetta opettaja antaa oppilailleen alakoulun englannin kielen tunneilla, ja millainen yhteys sillä on oppilaiden asenteisiin englannin kieltä kohtaan. Tutkimusaineisto koostui kolmesta opettajasta ja heidän oppilaistaan; yksi englannin kielen aineenopettaja ja hänen viidesluokkalainen ryhmänsä sekä kaksi luokanopettajaa ja heidän neljäs- ja viidesluokkalaisensa. Tutkimusaineisto koottiin metodisella triangulaatiolla. Aluksi oppilaille teetettiin kartoittava kysely …
The effect of perceived school climate and teacher efficacy in behavior management on job satisfaction and burnout: A longitudinal study
2016
Abstract This study investigated how perceived school climate affects teachers' job satisfaction and burnout and how self-efficacy and collective efficacy in behavior management mediate the effect of perceived school climate on job satisfaction and burnout. The questions were answered using longitudinal questionnaire data collected from 642 Finnish lower secondary school teachers. A structural equation model revealed that school climate had a positive effect, partly mediated by self-efficacy, on job satisfaction. Collective efficacy in student discipline did not explain either job satisfaction or burnout. Self-efficacy in managing behavior had a positive effect on job satisfaction and a neg…
Preservice teachers’ training through microteaching experience
2020
The efficient teaching and the reflexive one were long recognized as desirable purposes of teachers’ training programs. Several studies demonstrated that simulated experiences inside university paths are suitable means to achieve that aim to have prepared teachers to become efficient and reflexive teachers. One of the methods more common to provide experience for teachers in training is microteaching. The video-registration and the methodologies that use of it are increasingly used in the professional training of future teachers. The teacher's professionalism requests, in addition to theoretical or disciplinary knowledge, the ability to mobilize knowledge to organize effective responses to …
Teacher-student interaction and lower secondary school students’ situational engagement
2019
Background: Prior research has shown that engagement plays a significant role in students’ academic learning. Aims: The present study sought to expand the current understanding of students’ engagement by examining how situational engagement during a particular lesson is associated with the observed teacher–student classroom interactions (i.e., emotional support, instructional support, and classroom organization) in the same lesson. Sample: The participants were 709 Grade 7 students (47.7% girls) from 59 classrooms in 26 lower secondary schools and 51 teachers. Methods: The data consisted of 155 video‐recorded lessons (90 language arts and 65 mathematics lessons) coded using the Classroom As…
Transmission delay in technology-mediated interaction at work
2015
This paper investigates transmission delay in technology-mediated interaction from a participant’s perspective. The approach chosen here contrasts with previous studies of delay: only what is seen, heard and done at one end (i.e., what is available on screen) is considered in the analysis. It is argued that participants themselves lack access to the other sides of their interactions as they unfold at remote locations, and they thus cannot observe and deal with delay from an outside perspective. Analyzing single cases of delay-ininteraction within the framework of conversation analysis, the focus is on dispersed conversation partners’ resources to detect a problem, and to make visible and re…
