Learning Slovak in new language learning environments
2017
The aim of this dissertation is to throw light on the development of teaching and learning Slovak in the new language learning environment. New developments in teaching led to the design of an experimental e-learning course in Slovak based on the philosophy of dynamic learning and using the metaphor of climbing a mountain for learning Slovak. The course was grounded in constructivist views of learning and teaching, which emphasize the importance of learning by doing and the process-like nature of learning. The teaching experiment included reflection-on-action research, with the goal of exploring learners' beliefs about themselves as e-learners before the course, and their perceptions and ex…
Transformative technologies, spatial changes : essays on mobile phones and the Internet
2009
Sakari Taipale tarkastelee väitöskirjassaan sitä, kuinka matkapuhelimen ja internetin käyttö vaikuttaa sosiaalisten tilojen muodostumiseen.Uudet informaatio- ja kommunikaatioteknologiat ovat monipuolistaneet sosiaalisen vuorovaikutuksen muotoja. Matkapuhelimen ja internetin avulla sosiaalisia tiloja, erilaisia toimijoiden yhteenliittymiä, voidaan luoda tietoverkoissa ilman toisten ihmisten fyysistä läsnäoloa. Tämän seurauksena sosiaalisen tilan kahden keskeisen osatekijän, rajojen ja tarkoituksen, välinen suhde on muuttunut. Rajat näyttävät menettäneen suhteellista merkitystään sosiaalisen tilan koossapysyvyyden kannalta, kun taas tilan tarkoituksen merkitys on vahvistunut.- Verkkoympäristö…
The Networked Utilisation of Satellite Images and Geospatial Technology in Journalism
2022
Satellite technology has become increasingly affordable and accessible in the past few decades. This has enabled many newsrooms to engage with genuinely remote journalism. This chapter explores the networked nature of satellite journalism and investigates its inclusion of experts and citizens outside newsrooms. Satellite journalism uses satellite-borne technology either as a (1) part of storytelling or (2) source of information. Academic research on the topic is scarce, so this chapter builds a base of knowledge on the contemporary practices, limitations and ethics—as well as directions of future development—of satellite journalism. By interviewing six journalists and one earth observation …
Dry stone buildings in Sicily. An environmental and territorial resource
2013
Dry stone constructions are widespread throughout many regions across the world, in a wide variety of forms, according to the environmental and socio-economic contexts, and constitute a valuable know-how which is today in danger of disappearing. In Sicily dry stone works have traditionally been used in the area of Val di Noto where they constitute a key character of the landscape, and in the Madonie Mounts in which some policies of enhancement have been recently initiated. In the framework of the Grundtvig programme “La préservation du patrimoine architectural bâti en pierre sèche”, an in-depth analysis of these architectures have been pursued, aiming to create a database inventory. This pa…
Kinetic evidence for the incorporation of the [(pentamethylcyclopentadienyl) (2,2′-bipyridyl)(aquo)rhodium(III)] complex into DPPC vesicles
2008
Abstract The binding of the [(pentamethylcyclopentadienyl) (2,2′-bipyridyl)(aquo)rhodium(III)] complex [Cp*RhIII(bpy)H2O]2+, to l -α-dipalmitoylphosphatidyl choline (DPPC) vesicles has been estimated by studying the kinetics of the electron transfer reaction between the rhodium(III) complex and formiate ions. Kinetic measurements carried out under anaerobic conditions in absence and presence of DPPC show that the total reaction is composed of two steps. The rate of the first reaction increases with the phospholipid concentration, while that of the second process is independent of the concentration of DPPC. This is consistent with a reaction, where the two reacting species are partitioned be…
Structure and dynamics in liquid bismuth and Bin clusters: A density functional study
2014
Density functional/molecular dynamics simulations with more than 500 atoms have been performed on liquid bismuth at 573, 773, 923, and 1023 K and on neutral Bi clusters with up to 14 atoms. There are similar structural patterns (coordination numbers, bond angles, and ring patterns) in the liquid and the clusters, with significant differences from the rhombohedral crystalline form. We study the details of the structure (structure factor, pair, and cavity distribution functions) and dynamical properties (vibration frequencies, diffusion constants, power spectra), and compare with experimental results where available. While the three short covalent bonds typical to pnictogens are characteristi…
Sustaining Attention for a Prolonged Duration Affects Dynamic Organizations of Frequency-Specific Functional Connectivity
2020
Sustained attention encompasses a cascade of fundamental functions. The human ability to implement a sustained attention task is supported by brain networks that dynamically formed and dissolved through oscillatory synchronization. The decrement of vigilance induced by prolonged task engagement affects sustained attention. However, little is known about which stage or combinations are affected by vigilance decrement. Here, we applied an analysis framework composed of weighted phase lag index (wPLI) and tensor component analysis (TCA) to an EEG dataset collected during 80 min sustained attention task to examine the electrophysiological basis of such effect. We aimed to characterize the phase…
Aktywność sołectw wspierających rozwój społeczny w ramach Programu Odnowy Wsi w latach 2013-2015
2018
Odnowa wsi jako metoda rozwoju stanowi jeden ze sposobów osiągania celów rozwojowych, rozumianych nie tylko w kontekście poprawy jakości infrastruktury, ale poprawy szeroko rozumianej jakości życia, której nie osiągniemy bez zaangażowania samych mieszkańców. Celem artykułu jest przedstawienie Programu Odnowy Wsi (na przykładzie województwa opolskiego) jako elementu przyczyniającego się do rozwoju kapitału społecznego, czego wyrazem może być liczba przedsięwzięć realizowanych przez poszczególne sołectwa. Zostały przeanalizowane sprawozdania sołectw (około 600 rocznie) z realizacji programu w latach 2013-2015. Podstawową metodą prezentacji wyników badań jest analiza opisowa z użyciem metod il…
Applying Axial Symmetries to Historical Silk Fabrics: SILKNOW’s Virtual Loom
2020
Symmetry is part of textile art in patterns and motifs that decorate fabrics, which are made by the interlacement of warp and wefts. Moreover, the 3D representation of fabrics have already been studied by some authors
Damping Provision by Different Virtual Synchronous Machine Schemes
2020
The adoption of virtual synchronous machine (VSM) schemes for the control of power converters is gaining more and more attention both in academia and industry. The VSM control strategies fall into the category of grid-forming converter controls, and they are intended for a range of different applications, providing specific services and different kinds of support to the grid. The paper investigates the possibility of damping provision to the system by VSM power converters. Different schemes are considered and compared, showing the opportunity of the investigated solutions through combined modal and time domain analyses. A specific modification of the power synchronization loop is recognized…
