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…
From conceptualization to constructions in Finnish as an L2 : a case study
2017
AbstractThis study traces the individual learning trajectories of an adult beginner L2 Finnish learner in expressing the extralinguistic concept of evaluation from a dynamic usage-based perspective. Our results provide support for the view of learner language as a dynamic system in which patterns wax and wane and in which a change in one component has the potential to affect the whole system. In the early stages of learning there was a strong preference to use lexical verbs first, and then adjectives. The study also shows that variability plays a role. Finally, the study confirms that the learning of L2 constructions is in some cases item based. However, another highly frequent and superfic…
Anaerobisen kynnysharjoituksen päiväkohtainen vaihtelu ja kuntotason vaikutus vaihtelun määrään
2017
Johdanto. Kestävyyssuorituskykyyn vaikuttavat pääasiallisesti maksimaalinen hapenottokyky, pitkäaikainen aerobinen kestävyys, suorituksen taloudellisuus ja hermolihasjärjestelmän voimantuottokyky. Kestävyyssuorituskykyä mitattaessa pitää ymmärtää sen päiväkohtainen vaihtelu. Syke ja laktaatti ovat tyypillisiä muuttujia ja molemmissa on huomattu olevan vaihtelua suoritusten välillä. Myös kuntotasolla on katsottu olevan vaikutusta päiväkohtaiseen suorituskyvyn vaihteluun. Parempikuntoiset ovat tavallisesti toistettavampia. MLSS-vauhti on yksi tapa arvioida kestävyyssuorituskykyä. Menetelmät. Tutkimukseen osallistui 24 (11 miestä ja 13 naista) tutkittavaa vähintään vuoden kestävyysurheilutaust…
Accidents du travail dans l’UE-15 et méthodes d’apprentissage automatique
2020
Les méthodes d’apprentissage automatique ont été utilisées comme outil de prédiction dans denombreux domaines, mais leur utilisation en santé et sécurité au travail est relativement nouvelle.C’est la raison pour laquelle, il serait intéressant d’utiliser ces méthodes dans la prévision desaccidents du travail, sur les données d’enquêtes européennes sur les conditions de travail. L’objectifde ce travail est de tester les performances des techniques d’apprentissage automatique dans lamodélisation et la prédiction d’accidents du travail. A cette fin, nous utiliserons trois modèles :(les forêts aléatoires) (RF), Support Vector Machine (SVM), modèle logistique. Nous observonsque, la performance d…
Semi-natural habitats in boreal Europe: a rise of a social-ecological research agenda
2021
The European continent contains substantial areas of semi-natural habitats, mostly grasslands, which are among the most endangered habitats in Europe. Their continued existence depends on some form of human activity, for either production or conservation purposes, or both. We examined the share of semi-natural grasslands within the general grassland areas in boreal Europe. We reviewed research literature across the region to compile evidence on semi-natural grasslands and other semi-natural habitats, such as wooded pastures, in respect to a range of topics such as ecology, land-use change, socioeconomics, and production. We also explored drivers of the research agenda and outlined future re…
Modeling confidential data via modified hurdle mixed models

Working while studying: does it lead to greater attachment to the regional labour market?
2017
This chapter studies the link between working while studying and migration. Understanding this link is important because policy-makers are often calling for actions that would cut down the hours students spend on working to shorten the graduation time. The chapter’s analysis focuses on graduates from Finnish universities, polytechnics and vocational schools in 1991–2004. It uses rich register-based longitudinal microdata constructed by Statistics Finland, and find a negative relationship between working while studying and graduate migration. An increase in student employment can thus partly explain the decline in geographic mobility among Finnish graduates from higher education.
Problemløsning i matematikk : hvordan resonnerer elever på 9.trinn under arbeid med problemløsningsoppgaver i multiplikasjon?
2016
Masteroppgave matematikkdidaktikk – Universitetet i Agder 2016 This is a qualitative case study, which highlights students' reasoning in problem solving. The research question is: How do students in 9th grade reason while working with problem solving tasks in multiplication. The purpose of this study is to investigate how students in 9th grade reason while working with problem solving tasks. More knowledge about students' reasoning in problem solving, can contribute to appropriate use of this in teaching. I defined two sub-questions that is attempted to be answered in the discussion. The two sub-questions are: 1. How do students´ reason and which strategies do they use? 2. How do problem so…
Uniformly Path Connected Homogeneous Continua
2016
It is proven that every path connected homogeneous continuum is uniformly path connected, which answers a question of David P. Bellamy. From this result it follows that every path connected homogeneous continuum is continuously equivalent either to an arc, or to the Cantor fan.
