Identifying Finnish Children’s Impulsivity Trajectories From Kindergarten to Grade 4: Associations With Academic and Socioemotional Development
2015
Research Findings: The purpose of this study was to identify the developmental trajectories of impulsive behavior among 378 Finnish children who were followed from kindergarten to fourth grade. In addition to ratings of children’s impulsivity, the analyses included measures of motivation, cognitive skills, socio-emotional adjustment, and teacher–student relationship. Four latent groups were identified that differed in the level and change of the children’s impulsive behavior across time: first, a group with low impulsivity; second, a group with decreasing impulsivity; third, a group with moderate impulsivity; and, fourth, a small group with a contradictory trajectory showing an upward trend…
Gold catalyzed stereoselective tandem hydroamination–formal aza-Diels–Alder reaction of propargylic amino esters
2013
A gold-catalyzed tandem intramolecular hydroamination-formal aza-Diels-Alder reaction of propargylic amino esters is described. The overall process leads to the formation of a tetracyclic framework as a single diastereoisomer, with the creation of four bonds and five stereocenters.
Fast proton conduction in hydrogen bonded microheterogeneous systems: Bis(2-ethylhexyl)phosphoric acid/N-methyl formamide liquid mixtures
2009
Structural and dynamical properties of bis(2-ethylhexyl)phosphoric acid (HDEHP)/N-methyl formamide (NMF) liquid mixtures in the whole composition range have been investigated by Fourier Transform Infrared spectroscopy (FT-IR), X-rays Diffraction (XRD), and AC complex impedance spectroscopy. Driven by hydrogen bond interactions among HDEHP PO(4)H group and NMF CO and NH groups, and also by steric effects among the HDEHP alkyl chains, the system microstructure is mainly characterized by the coexistence of spatially separated hydrophilic and hydrophobic nanodomains showing local organization and short-range order. The evolution of this structural feature with system composition has been highli…
Unveiling the environment and faint features of the isolated galaxy CIG 96 with deep optical and HI observations
2018
Context. Asymmetries in atomic hydrogen (HI) in galaxies are often caused by the interaction with close companions, making isolated galaxies an ideal framework to study secular evolution. The AMIGA project has demonstrated that isolated galaxies show the lowest level of asymmetry in their HI integrated profiles compared to even field galaxies, yet some present significant asymmetries. CIG 96 (NGC 864) is a representative case reaching a 16% level. Aims. Our aim is to investigate the HI asymmetries of the spiral galaxy CIG 96 and what processes have triggered the star-forming regions observed in the XUV pseudo-ring. Methods. We performed deep optical observations at CAHA1.23m, CAHA2.2m and V…
The Perception of Causality in Light of Process Ontology
2015
Human perception has an important emotional dimension. Besides having a “presentational” element that dominates the high cognitive activities of human beings, there are certain “densities of feelings,” which are inextricably intertwined with the presentational contents of our perceptual states. This does not mean that human perception is just instinctive, irrational, or intrinsically subjective. The Whiteheadian scheme allows us to determine the nature of the “emotional background” of perception without falling into the traps of subjectivism, representationalism, or substantialism. The feeling which I call “the sense of physicality” is just one of the elements of this emotional dimension in…
ELINET-symposium kokosi yhteen lukutaitotoimijoita : kansainvälisestä yhteistyöstä intoa työhön
2018
ELINET-verkosto (European Literacy Policy Network) järjesti heinäkuun lopulla lukutaitosymposiumin Kölnissä, Saksassa. Symposiumiin kokoontui satakunta lukutaitotutkijaa, opettajaa ja kouluttajaa sekä lukutaidon parissa järjestötyötä tekevää asiantuntijaa lähes 20 maasta. Symposiumin teemoina olivat osallisuus, inkluusio ja tasa-arvo. nonPeerReviewed
Biased GraphWalks for RDF Graph Embeddings
2017
Knowledge Graphs have been recognized as a valuable source for background information in many data mining, information retrieval, natural language processing, and knowledge extraction tasks. However, obtaining a suitable feature vector representation from RDF graphs is a challenging task. In this paper, we extend the RDF2Vec approach, which leverages language modeling techniques for unsupervised feature extraction from sequences of entities. We generate sequences by exploiting local information from graph substructures, harvested by graph walks, and learn latent numerical representations of entities in RDF graphs. We extend the way we compute feature vector representations by comparing twel…

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…
IDS sistēmas ieviešana augstas veiktspējas tīklu drošības monitoringam ar atvērtā pirmkoda rīkiem un patēriņa aparatūru
2019
Darba mērķis ir izpētīt, kā izmantot atvērtā pirmkoda IDS sistēmas ar patēriņa aparatūru, lai monitorētu drošību augstas veiktspējas tīklos, kuros tīkla caurlaidība pārsniedz 10Gbit/s. Lai parādītu, kāds ir veiktspējas ieguvums no dažādām ar veiktspēju saistītam izmaiņām IDS sistēmā, mērķis ir veikt sistēmas ieviešanu, kur tiek veiktas izmaiņas pa posmiem un tiek iegūti rezultāti par izmaiņām veiktspējas rādītājos. Darbā tika pētīti ar IDS sistēmas veiktspējas uzlabošanu saistīti akadēmiskie darbi, lai apkopotu tajās izmantotās metodes, kas ir palīdzējušas sasniegt augstus IDS sistēmas veiktspējas rādītājus. Darba praktiskajā daļā tika ieviests pakešu ģenerators IDS sistēmas veiktspējas tes…
