Using the Questionnaire on Experience and Assessment of Work with the Italian Population
2010
The assessment of work-related stress has been an issue that has attracted attention of Italian psychologists for a long time, but only in recent years it has been remarked in the laws protecting workers. In fact, it has just been recalled the need, in a legislative decree, to place special emphasis on psychological well-being of the worker and not just on his security. The Italian professionals (Work, Organizational or Personnel Psychologists) who worked on the assessment of psychological risks of work-related stress, used instruments to assess the organizational climate primarily, by integrating qualitative m ethodologies (such as focus group) with quantitative instruments. These instrume…
Taking the acid test: Mediterranean limpets face up to climate change
2014
Impacts of climate change involve the interactions of multiple stressors on intertidal organisms, but rarely are the impacts of these stressors examined together. Many tests are also conducted in artificial, controlled laboratory conditions, without making use of natural opportunities to test performance of organisms under different environmental stressors. Given its small tidal range, the Mediterranean Sea provides such an opportunity, with a very fine scale environmental gradient and species living very close to each other over the tidal gradient. The vertical distribution of the limpets, Patella rustica and P. caerulea overlap in Palermo, Sicily, but despite this they have different ther…
Volatile oil content of Scots Pine needles (Pinus sylvestris L.)
2016
Badania dotyczą zmienności zawartości olejku eterycznego w igliwiu sosny zwyczajnej w zależności od wieku drzew, garnituru igieł oraz jego usytuowania w koronie. Materiał do badań stanowiło igliwie zebrane z drzewostanów sosnowych w wieku 15, 44 i 89 lat. W przeprowadzonych badaniach średnia zawartość olejków wzrastała wraz z wiekiem drzew. W igliwiu pochodzącym z 15-letniego młodnika zawartość olejku wynosiła średnio 0,46%, a w igliwiu drzewostanów 44- i 89-letnich odpowiednio 0,55 i 0,61%. Średnia zawartość olejku maleje wraz z wiekiem igliwia. Najwięcej olejku zawiera igliwie jednoroczne - 0,56%, najmniej igliwie trzyletnie - 0.48%. W drzewostanie 15-letnim stwierdzono wyraźny wzrost wyd…
WRKY gene family drives dormancy release in onion bulbs
2022
Onion (Allium cepa L.) is an important bulb crop grown worldwide. Dormancy in bulbous plants is an important physiological state mainly regulated by a complex gene network that determines a stop of vegetative growth during unfavorable seasons. Limited knowledge on the molecular mechanisms that regulate dormancy in onion were available until now. Here, a comparison between uninfected and onion yellow dwarf virus (OYDV)-infected onion bulbs highlighted an altered dormancy in the virus-infected plants, causing several symptoms, such as leaf striping, growth reduction, early bulb sprouting and rooting, as well as a lower abscisic acid (ABA) level at the start of dormancy. Furthermore, by compar…
Opetusryhmän rakenteeseen ja opettajaan liittyvien tekijöiden yhteydet opettajan ohjauskäytäntöihin

Kasvatustieteen pro gradu -tutkielma. 85 sivua. Tutkimuksen tavoitteena oli analysoida 1. luokan opetusryhmissä havainnoitujen ohjauskäytäntöjen laatua sekä selvittää opetusryhmän rakenteeseen (lasten ja aikuisten sekä avustajien lukumäärä luokassa) ja opettajaan liittyvien tekijöiden (koulutus, työkokemus ja kuormitus) mahdollisia yhteyksiä ohjauskäytäntöjen laatuun. Tutkimus on osa Alkuportaat -seurantatutkimusta (Lapset, vanhemmat ja opettajat koulutien alkupolulla), jossa lapsia seurataan esiopetusvuodesta n…
Academic achievement and self-concept of deaf and hard-of-hearing and hearing students transitioning from the first to second cycle of primary school…
2018
ABSTRACTThis study was done to examine the transition of deaf and hard-of-hearing (DHH) and hearing students from the first cycle (Grade 4) to the second cycle (Grade 5) of primary education in Ethiopia. Academic achievement and self-concept were measured longitudinally with 103 DHH and hearing students. Participants were selected from three different settings (special schools, special classes and regular schools). Self-Description Questionnaire I (Marsh, H. W. 1990. Self-Description Questionnaire – I (SDQ I). Manual. MacArthur, NSW, Australia: University of Western Sydney) was used to measure the children’s self-concept. The results showed a decrease in the academic achievement and academi…
Behavioural and emotional strengths of sociometrically popular, rejected, controversial, neglected, and average children
2019
Many behavioural and emotional characteristics are associated with children’s peer relationships. The purpose of this study is to examine behavioural and emotional strengths of sociometrically popular, rejected, controversial, neglected, and average children. 773 third-grade children (51% girls) are assessed with a sociometric questionnaire and self-evaluations of their behavioural and emotional strengths and difficulties. Teacher evaluations are also used to assess the children’s academic competencies and behaviour. Univariate analysis of variance (ANOVA) is used to analyse the data. Results indicate that children in the popular status group assess their behavioural and emotional strengths…

Teachers' physiological and self-reported stress, teaching practices and students' learning outcomes in Grade 1.
2022
Background Teachers' self-reported stress is related to the quality of teacher–student interactions and students' learning outcomes. However, it is unclear if teachers' physiological stress is related to child-centred teaching practices in the classroom and whether teaching practices mediate the link between teachers' stress and students' learning outcomes. Aims We studied the effect of teachers' physiological stress and self-reported stress on their teaching practices and thereby on students' learning outcomes in math. Sample A total of 53 classroom teachers and 866 Grade 1 students participated in the study. Methods Salivary cortisol in the middle of the school day and cortisol slope from…
Critical Exploration of Flexible Delivery
2020
This work-in-progress research article presents an introductory qualitative study on students' perceptions of a flexibly delivered, modular computer science course. Many contemporary approaches to education rely in various ways on flexible delivery of course content. This is often done to capitalize on modern technology and the web, and to put the student ‘in the center.' However, it is becoming manifest that these approaches may challenge both the students and the equity between them, making it important to understand the effects of flexible delivery in terms of the students. In the voice of our students, flexible delivery was seen as a largely positive approach, reducing stress, promoting…
