Transporta plūsmu kustības ātruma un strukturālo izmaiņu modelēšana Valdemāra ielas kanjona posmos
2015
Bakalaura darba ietvaros pētīta autotransporta radītā atmosfēras piesārņojuma izplatība Rīgā, Valdemāra ielas kanjonā. Kā indikators ietekmes novērtēšanai izmantotas slāpekļa dioksīda koncentrācijas, kuras cieši korelē ar transporta līdzekļu plūsmas intensitāti; bez tam regulāri tiek pārsniegti slāpekļa dioksīdam noteiktie stundas un gada normatīvi. Piesārņojuma izplatība novērtēta izmantojot matemātisko modelis OSPM, kurš speciāli izstrādāts transporta radītā piesārņojuma dispersijai un raksturošanai. Darbā aprakstīta transporta plūsmas dinamika dažādiem dienu profiliem un izveidota datu bāze modelēšanai, raksturota piesārņojuma problemātika ielu kanjonos, modelēšanas ceļā novērtēta apbūve…
Modeling the Sustainable Educational Process for Pupils from Vulnerable Groups in Critical Situations: COVID-19 Context in Lithuania, Latvia, and Est…
2022
The critical situation in education caused by COVID-19 has significantly reduced the involvement of pupils from vulnerable groups, particularly those with low learning achievements. The aim of this study is to reveal the modeling of the sustainable educational process and the factors that ensure optimal learning achievements of pupils from vulnerable groups in general education schools in critical educational transformation situations. To reveal the factors ensuring the sustainability of educational processes, this study was conducted in three Baltic countries (Lithuania, Latvia, and Estonia) involving 1432 subject teachers from public education schools. The results of the study highlight t…
Trust and team identification at multicultural workplaces : perceptions of Finnish HR professionals
2017
Growing global mobility has rapidly diversified workplace demographics across the world. Finland that has traditionally been considered a relatively uniform nation in terms of cultural and ethnic diversity has also experienced a shift in its population in recent decades. Despite the growing multiculturalism, established diversity management practices are yet to be developed in many Finnish organizations, and the subject has not gained much academic attention either. Still, competent intercultural leaders are often vital for both successful business results and for the well-being of their multicultural teams. The aim of this thesis is to shed light on the current state of international human…
In pursuit of beginning teachers'competence in promoting reading motivation: a mixed-methods study into the impact of a contunuing professional devel…
2020
As teachers’ reading motivation and self-efficacy for promoting reading motivation can be considered vital for their reading-oriented promotive teaching practices and students’ reading motivation, this study evaluated the impact of a year-long CPD program for beginning primary school teachers. A convergent parallel mixed-methods design with repeated measures was established, including a comparison and two CPD conditions (group vs. individually-oriented). Based on the quantitative results only no clear impact of and differences between the conditions could be observed. The qualitative analysis, however, showed growth in teachers’ reading motivation and self-efficacy at a different pace and l…
Resting State EEG Directed Functional Connectivity Unveils Changes in Motor Network Organization in Subacute Stroke Patients After Rehabilitation
2022
Brain plasticity and functional reorganization are mechanisms behind functional motor recovery of patients after an ischemic stroke. The study of resting-state motor network functional connectivity by means of EEG proved to be useful in investigating changes occurring in the information flow and find correlation with motor function recovery. In the literature, most studies applying EEG to post-stroke patients investigated the undirected functional connectivity of interacting brain regions. Quite recently, works started to investigate the directionality of the connections and many approaches or features have been proposed, each of them being more suitable to describe different aspects, e.g.,…
Sustainability Development in Mathematics Education : A Case Study of What Kind of Meanings Do Prospective Class Teachers Find for the Mathematical S…
2019
In this article, our focus is on sustainable development in mathematics education from the point of view of teacher training. The aim was to develop prospective teachers’ content knowledge and pedagogical content knowledge of school mathematics. As a case study, we chose the mathematical symbol “a/b”, and examined how prospective class teachers in Finland connect it to the concepts of fraction, ratio, division, rational number or probability. Mathematics textbooks often have a central role in lessons, and they affect strongly how pupils understand concepts and the relationships between them. We chose languaging as a multi-semiotic approach to interpreting what kind of meanings the prospecti…
"What is the color of English?" : representation of English in the language portraits of Sámi children
2010
Tutkimus on osa Jyväskylän yliopiston kielten laitoksen Pohjoinen monikielisyys - hanketta, jonka tavoitteena on tutkia monikielisyyttä Pohjoiskalotin alueella. Projektissa hyödynnetään sosiolingvistiikkaa, kriittistä diskurs-sintutkimusta ja etnografiaa. Tässä tutkimuksessa esiin nousevat mm. kielentäminen, heteroglossia ja kieli-politiikka. Lähtökohtana ovat henkilökohtaiset kielikokemukset, resurssit ja repertuaarit, ja niiden tutkiminen multimodaalisen aineiston avulla. Erityisen kiinnostuksen kohteena on yksittäisen kielen, englannin, esiin-tyminen aineistossa. Vastaavaa näkökulmaa samantyyppiseen aineistoon ei ole aiemmin hyödynnetty. Tutkimuksen aineisto koostuu neljäntoista 6-12 vuo…
Media landscapes in school and in free time – two paralel realities?
2008
This article is based on an extensive research project (Towards Future Literacy Pedagogies, ToLP1 ) that deals with the literacy practices of Finnish and immigrant pupils, mother tongue (MT) and foreign language (FL) teachers. The overall aim of the project is to explore and interpret literacy practices both in school and out-of-school contexts by employing large-scale quantitative research approaches as well as qualitative classroom observations and teacher and pupil interviews. In this article, we will report findings of the comprehensive survey, our specific focus being on the materials and media the teachers and pupils use in school and in their free time. We are interested in exploring…
Calibration of the underground muon detector of the Pierre Auger Observatory
2021
To obtain direct measurements of the muon content of extensive air showers with energy above $10^{16.5}$ eV, the Pierre Auger Observatory is currently being equipped with an underground muon detector (UMD), consisting of 219 10 $\mathrm{m^2}$-modules, each segmented into 64 scintillators coupled to silicon photomultipliers (SiPMs). Direct access to the shower muon content allows for the study of both of the composition of primary cosmic rays and of high-energy hadronic interactions in the forward direction. As the muon density can vary between tens of muons per m$^2$ close to the intersection of the shower axis with the ground to much less than one per m$^2$ when far away, the necessary bro…
