Nuorten urheilupolut : tutkimus kilpaurheiluun sosiaalistumisen normeista, pääomista ja toimijuudesta
2016
Sport is a popular activity among Finnish children and adolescents. Junior sport encompasses various objectives, and one of its functions is to generate the prerequisites for competitive sport and an elite sports career. This study examines socialization into competitive sport. It approaches the socialization process as a sports path that denotes the sequence of states and events in sport as part of one’s life course. The study emphasizes experiences and through them the meaning-giving and lifeworld of the young athletes themselves. Hence, the aim of the study is to create a sociological interpretation of athlete development. The research data comprise a survey of 2,430 registered participa…
ICAnDoiT: the impact of computerised adaptive corrective feedback on L2 English learners
2016
The present dissertation examines the impact of (computerised) adaptive corrective feedback, that is, feedback dynamically adapting to learners’ abilities, in English as a second/foreign language (L2) and explores the ways to maximise this impact. The study was inspired by the sociocultural perspective on development, which had implications for the interpretation of the results, including those obtained through statistical data analyses. The dissertation comprises five articles and a synthesis. In the first article, a positive effect of adaptive corrective feedback on the learners’ ability to formulate L2 English wh-questions is established. The second article explores how learners’ beliefs…
EFL Teacher Education in Finland : Manifestations of Professional Agency in Teacher Educators’ Work
2020
English as a Foreign Language (EFL) teacher educators play a key role in the development of university-based teacher education and the preparation of preservice EFL teachers. However, the professional agency of EFL teacher educators in developing their work remains understudied. Employing a Vygotskian sociocultural theoretical perspective, this research considers the individual and collective professional agency of eight EFL teacher educators at two Finnish universities. Findings demonstrate that individual professional agency is enacted in the expression of professional identity and the development of professional relationships, and in offering and receiving professional assistance. Findin…
Organizational identity and competition : a study of US semiconductor industry
2017
Organisationaalinen identiteetti ja kilpailu : tutkielma puolijohdeteollisuudesta. Tutkimuksen tehtävänä on selvittää, miten kaksi samalla puolijohdesektorilla kilpailevaa yritystä, Intel Corporation ja Advanced Micro Devices, kuvailee itseänsä ja kenttäänsä suhteessa kilpailijoihinsa ja siten rakentaa ja ylläpitää organisationaalista identiteettiään. Tutkimuksen teoreettisena näkökulmana on tarkastella markkinoita sosiaalisesti rakentuneena kenttänä jota kilpailu ylläpitää. Analyysimenetelmänä on käytetty koneoppivaa tekstin mallinnusmenetelmää nimeltä Latentti Dirichlet Allokaatio (LDA), jolla …

The Industrial Applicability of PEA Space Charge Measurements, for Performance Optimization of HVDC Power Cables
2019
Cable manufacturing industries are constantly trying to improve the electrical performance of power cables. During the years, it was found that one of the most relevant degradation factors influencing the cable lifetime is the presence of space charge in the insulation layer. To detect the accumulated charge, the pulsed electro-acoustic (PEA) method is the most used technique. Despite the wide use of the PEA cell, several issues are still present. In particular, the PEA output signal is strongly disturbed by the acoustic waves reflections within the PEA cell. This causes the distortion of the output signal and therefore the misinterpretation of the charge profiles. This, in turn, may result…
Spazio e lingua nella 'costruzione' greca dell'identità etnica. Alcune osservazioni a partire da Erodoto
2018
The paper aims to offer an account of some representative opinions of ancient Greeks about the role of the space, conceived in its geographical/environmental value, in which a certain population lives, as well as of the language spoken by a population, in order to build historically the concept of Greek nation (to Hellenikón). The different positions expressed on these matters by Herodotus, Thucydides, Strabon and Pausanias are discussed, and the examination mostly concernes the ethnic and historical-linguistic aspects of the representation of the Dorians and Ionians.
SparseHC: A Memory-efficient Online Hierarchical Clustering Algorithm
2014
Computing a hierarchical clustering of objects from a pairwise distance matrix is an important algorithmic kernel in computational science. Since the storage of this matrix requires quadratic space with respect to the number of objects, the design of memory-efficient approaches is of high importance to this research area. In this paper, we address this problem by presenting a memory-efficient online hierarchical clustering algorithm called SparseHC. SparseHC scans a sorted and possibly sparse distance matrix chunk-by-chunk. Meanwhile, a dendrogram is built by merging cluster pairs as and when the distance between them is determined to be the smallest among all remaining cluster pairs. The k…
Predictive models in assessment of macroinvertebrates in boreal rivers
2009
Jukka Aroviita tutki väitöskirjassaan jokien ja purojen biologisen tilan mittaamismenetelmiä. Aroviita osoitti, että ihmistoiminnan aiheuttamat biologiset muutokset voivat jäädä havaitsematta, jos eliöyhteisöjen luonnollista taustavaihtelua ei oteta kunnolla huomioon.- Tällöin vesistöjen saatetaan arvioida olevan paremmassa kunnossa kuin ne todellisuudessa ovatkaan. Muutosten tunnistamistarkkuuden tulisi olla mahdollisimman hyvä, sillä tila-arvioilla on myös juridisesti määräytyviä yhteiskunnallisia ja taloudellisia seuraamuksia, Aroviita toteaa. Vielä 1990-luvulla järvien ja jokien tilaa arvioitiin suurelta osin ihmisen näkökulmasta ja veden kemian perusteella. Nykylainsäädäntö edellyttää …
Forme necessarie dell’abitare: il ruolo dello spazio pubblico nei contesti informali di Bogotá e Medellín
2015
Gli spazi collettivi rappresentano un beneficio per la comunità, specialmente in quei contesti urbani “informali”, manifestazione fisica del bisogno primordiale dell’abitare. La straordinaria e recente rigenerazione urbana e sociale conquistata dalle città colombiane di Bogotá e Medellín, è un notevole esempio di strategie politiche e progettuali innovative, risultato delle azioni congiunte di politici, professionisti e cittadinanza, che fondano le proprie radici sul riconoscimento del ruolo sociale ed urbano dello spazio pubblico, elemento ristrutturante il tessuto urbano ed umano. La progettazione di nuovi spazi collettivi nei contesti urbani più fragili, più marginali ed abbandonati dell…
