Hölder regularity for stochastic processes with bounded and measurable increments
2022
We obtain an asymptotic Hölder estimate for expectations of a quite general class of discrete stochastic processes. Such expectations can also be described as solutions to a dynamic programming principle or as solutions to discretized PDEs. The result, which is also generalized to functions satisfying Pucci-type inequalities for discrete extremal operators, is a counterpart to the Krylov-Safonov regularity result in PDEs. However, the discrete step size $\varepsilon$ has some crucial effects compared to the PDE setting. The proof combines analytic and probabilistic arguments.
Improving the operation of an emergency department by using a simulation model
2007
FL Toni Ruohonen on tutkinut väitöskirjassaan monia suomalaisia koskettavaa ongelmaa: terveydenhuollon päivystysjärjestelmän tehottomuutta. Tietokonesimulointia apuna käyttäen Ruohonen kehitti päivystyspoliklinikan uuden toimintamallin, jolla päivystykseen tulevan potilaan hoitoprosessia voidaan nopeuttaa jopa 40 %. – Terveydenhuollon yksiköt ovat hyvin monimutkaisia kokonaisuuksia, ja niillä on paljon satunnaisia piirteitä. Uusien teoreettisten ratkaisumallien kehittäminen ongelmiin on ollut melko helppoa, mutta niiden toimivuus on voitu osoittaa vasta käytännön kokeilun jälkeen, Ruohonen toteaa.Tutkimuksessa Ruohonen loi aluksi tietokoneella mallin oikeasta poliklinikasta sairaalan henkil…
Method and Practical Guidelines for Overcoming Enterprise Architecture Adoption Challenges
2017
During the last few years, interest towards Enterprise Architecture (EA) has increased, not least due to anticipated benefits resulting from adopting it. For instance, EA has been argued to provide cost reduction, technology standardisation, process improvement, and strategic differentiation. Despite these benefits, the EA adoption rate and maturity are still low. Consequently, EA benefits are not realised. A major reason hindering the adoption is that EA is not understood correctly. This paper aims for minimising the effect of the lack of understanding EA to adopting EA. Based on the research conducted in Finnish public sector, we propose an improved Enterprise Architecture Adoption Method…
Measuring syntactic complexity in learner Finnish
2020
In the study of complexity, accuracy and fluency (CAF), syntactic complexity can be measured by a multitude of measures. Traditionally, the measures are quantitative and they use production units such as words, clauses, T -units, and sentences. Despite the vast number o f measures available, many studies have used only one or two of them, or parallel ones tapping the same component of complexity. The present study explores syntactic complexity using seven frequently used quantitative complexity measures to gauge different facets of complexity in written learner Finnish. The data of the study consist of texts written by adult and adolescent language learners, and they cover proficiency level…
Dynamic Usage-based Principles in the Development of L2 Finnish Evaluative Constructions
2021
Abstract This study investigates the formal verbalizations of evaluation used by four beginning L2 learners of Finnish from a dynamic usage-based perspective. Longitudinal data collected weekly were used to investigate what kind of constructions learners use to express evaluation and how these interact and develop over time. The results show that when a new construction is acquired in the L2, another related construction might regress. The results also point to increased variability in the construction during a phase of rapid development and reduced variability in the phases of regression or slower progress. These findings add to our understanding of a developing L2 as a system in which cha…
Words, clauses, sentences, and T-units in learner language: Precise and objective units of measure?
2020
In research on learner language complexity, accuracy and fluency (CAF), syntactic complexity is often studied with quantitative measures based on words, clauses, sentences, and T-units. The findings have been mixed, but segmenting learner language into these units of measure has seldom been problematised, even if the need for accurate coding is well known. The present study explores words, clauses, sentences, and T-units as production units in written learner language using a corpus of 352 L2 Finnish texts (28,813 words). The results illustrate how written learner language can be hard to fit into the production unit categories, which are essential for the most frequently used quantitative m…
Guiding and assessing development of L2 writing process : the role of peer collaboration
2022
This study, informed by Vygotskian notion of mediation and reporting on a partnership between a researcher (the first author) and a teacher (the second author), aims at exploring how peers’ comments can inform teacher assessment and guidance of learners’ L2 (second/foreign language) writing. The participants were 19 L2 English learners in an upper secondary school in Finland. We largely focus on the notes that one pair of learners made on each other’s essays and how they responded to peer assistance. Triangulating these data with classroom observation and a questionnaire, we traced how learners co-constructed their understanding of how their texts can be developed. The foci and how the iden…
Mehrsprachigkeit von Lernern mit Migrationshintergrund im finnischen Fremdsprachenunterricht : Perspektiven der Lerner, Lehrpersonen und Erziehungsbe…
2016
The goal of this study is to examine how the relatively new phenomenon of multilingualism in the Finnish education system is presently managed in foreign language classes in the Finnish comprehensive school. The focus is on how bi- and multilingual learners with migration background can benefit from their previous individual language experiences, language learning experiences and language awareness processes, and how these function as a resource for their further (foreign) language learning process. Until now migration research in the Finnish context concentrating on language learning mainly consists of second language acquisition. This study, however, focusses on foreign language learning …

Confocal laser scanning microscopy for the study of the morphological changes of the postextraction sites
2012
A better understanding of the remodeling process of postextraction sockets is essential in dental treatment planning. The aim of this study was to evaluate whether confocal laser scanning microscopy (CLSM) can be applied to imaging contour changes of postextraction sites, as well as to its quantification with image analysis of obtained three-dimensional images. This work describes a new application of the CLSM technique. The system used was the OLS3100-USS, LEXT model (Olympus((R))). CLSM was used for the surface analysis of the extraction site. The measurements taken with CLSM were: (1) mesio-distal distance, (2) alveolar ridge thickness, and (3) vestibular and lingual alveolar ridge heigh…
