Influence of the learning environment on the representational strategies of middle school music students: an intervention-based study
2015
The purpose of this study was to examine the effects of a hypermedia learning environment on middle school students' meta-representational competence (MRC) in the domain of music. Particularly, we aimed at determining whether an educational intervention influenced the accuracy with which middle school students matched sounds (sonic fragments) to symbols (graphic representations). The students were randomly allocated to the experimental condition. An intervention was set up so that the experimental group students (E) were provided with scaffolding aimed at enhancing their use of constructive resources to generate representations and their critical capabilities to judge them. On the other han…
Kriptogrāfisko valūtu ietekme uz starptautisko ekonomiku
2018
Mūsdienu pasaulē jau ir aptuveni tūkstotis dažādu kriptogrāfisko valūtu, no kurām populārākā ir bitkoins. Pieprasījums pēc šīs valūtas ir pieaudzis rekordlielā ātrumā un joprojām nav nokrities līdz tādiem skaitļiem, kādi bija pašā bitkoinu sākumā. Kriptogrāfiskās valūtas piesaista lielu uzmanību un lielākā daļa cilvēku mēģina izprast, kā tās darbojās. Pastāv daudzi viedokļi par kriptogrāfiskajām valūtām: 1. Kriptogrāfiskās valūtas noteikti mainīs pasauli. 2. Kriptogrāfiskajai valūtai piemīt burbuļa efekts un tuvākajā nākotnē tā pazudīs. 3. Kriptogrāfiskās valūtas ir jauns naudas veids, kurš sniedz dažādas priekšrocības tās lietotājiem. Gandrīz visas kriptogrāfiskās valūtas darbojās ar blokķ…
Stratēģijas skolēnu digitālās lasīšanas prasmju attīstīšanai angļu valodas stundās 7. klasē
2022
Lai lasītu digitālajā vidē ir jāattīsta īpašas digitālās lasītprasmes, piemēram, navigācijas prasmes un pašregulācija. Lasīšanas stratēģijas palīdz pielietot un attīstīt digitālās lasīšanas prasmes. Diplomdarba mērķis bija noteikt, kā lasīšanas stratēģiju īstenošana attīsta digitālās lasītprasmes angļu valodas stundās 7. klasē. Izvēlētā pētījuma metode bija gadījuma izpēte. Datu vākšanas metodes bija skolēnu aptauja, intervijas ar diviem skolotājiem, lasīšanas nodarbību novērojumi, skolēnu grafikas organizatori un mājas uzdevumi. Rezultāti liecina, ka skolotājiem un skolēniem ir pozitīva attieksme pret digitālo lasīšanu angļu valodas stundās. Tomēr studentiem ir nepieciešama papildu palīdzī…
Versions of Care Technology
2007
The importance of users for innovation has been increasingly emphasized in the literatures on design and management of technology. Less attention has been given to how people shape technology-in-use. This paper first provides a review of literature on technology use in the social and cultural studies of technology. It then moves to examine empirically how a novel alarm and monitoring appliance was appropriated in the work of home-care nurses and in the everyday living of elderly people. Analysis shows that even these technically unsavvy users shaped the technology considerably by various, even if mundane, acts of adapting it materially, as well as by attributing different meanings to it. Ho…
Monografie di Agathòn. Atti del Symposium East-West Artistic and Technological Contaminations/Oriente-Occidente. Contaminazioni Artistiche e Tecnolog…
2013
AgAthón, the Ph.D.’s journal collecting together the best of the works about the renovation and the enhancement of ancient contexts, has had increasing success among institutions and both Italian and foreign researchers. The choral pattern chosen in the four sectors, which alludes to the Greek city, has certainly contributed to create this appreciation: the Agorá, like the central space in the pólis, for guest contributions; the Stoá, the covered portico under which the philosopher Zeno used to teach his disciples, for the Ph.D. teachers’ contributions; the gymnásion, the place of endeavour for young Greeks training their bodies and minds, is the section meant for the doctoral candidates; l…
Finding a way to win: on competition, internationalization and MOOCs
2014
In the context of the ever growing use of technology through e-learning and open-courseware, my paper presents a project that is being carried out by a consortium of twelve partners and is coordinated by the University of Maastricht. This project sets out to examine the evolution of the innovative modes of higher education provision in teaching and learning across Europe, the motivations for their emergence as well as the ways in which higher education management and governance have responded and adapted to such new modes of provision. In the highly competitive sector of HE, while attempting to enhance the quality of teaching and learning, the increasing range of teaching and learning provi…
Optical Optimization of the TiO
2018
In this work, SiO2 nanoparticles (NPs) were integrated into the mesoporous TiO2 layer of a perovskite solar cell to investigate their effect on cell performance. Different concentrations of SiO2/ethanol have been combined in TiO2/ethanol to prepare pastes for the fabrication of the mesoporous layer with which perovskite solar cells have been fabricated. Addition of SiO2 NPs of 50 and 100 nm sizes produces an enhancement of cell performance mainly because of an improvement of the photocurrent. This increment is in good agreement with the theoretical predictions based on light scattering induced by dielectric SiO2 NPs. The samples using modified scaffolds with NPs also present a significant l…
Contributions to risk injury evaluation of human skin contact caused by welding technology in mechanical engineering a company
2017
Assembly by welding is a very important pollutant technological process, mainly of the atmosphere and soil. The formation of gas in welding process is the result of electrodes, fluxes burning, formation of fused bath and welded seam. A large number of human operators feels different adverse effects on health. Most problems appears in respiratory system and include bronchitis, respiratory irritation, fever caused by smoke, changes in lung function, decreased immunity to infection and a possible increase of lung cancer risk. Very little information are available about effects on the organism and skin after exposure to fumes from welding, therefore. In this order, this paper do a risk assessme…
Direct visualization of pyrrole reactivity by confined oxidation in a Cyclodextrin Metal‐Organic Framework
2019
Metal-organic frameworks can be used as porous templates to exert control over polymerization reactions. Shown here are the possibilities offered by these crystalline, porous nanoreactors to capture highly‐reactive intermediates for a better understanding of the mechanism of polymerization reactions. By using a cyclodextrin framework the polymerization of pyrrole is restricted, capturing the formation of terpyrrole cationic intermediates. Single‐crystal X‐ray diffraction is used to provide definite information on the supramolecular interactions that induce the formation and stabilization of a conductive array of cationic complexes.
