Personas datu aizsardzības regulējums ES, tā nepilnības, nākotnes izmaiņas un to ietekme uz datu aizsardzības regulējumu ES un Latvijā
2015
Mūsdienu informācijas tehnoloģiju laikmetā, kad interneta lietotāju skaits ir lielāks kā jebkad un tiešsaistē piedāvātie pakalpojumi tiek izmantoti līdz šim nepieredzētā apjomā, arī personas datu ievākšanas, apstrādes un uzglabāšanas procesi noris neiedomājamā mērogā. Šī iemesla dēļ par ļoti aktuālu ir kļuvis jautājums, vai Eiropas Savienība ir pienācīgi novērtējusi nepieciešamību pēc kvalitatīva personas datu aizsardzības tiesiskā regulējuma un vai pašreizējais regulējums nodrošina pietiekami augstu personas datu aizsardzības līmeni. Darba mērķis ir analizēt, kā un kādā mērā ES tiesību akti aizsargā personas tiesības uz savu datu aizsardzību, kā arī aplūkot un analizēt Eiropas Komisijas ie…
Public policies for the elderly from a human rights based approach
2021
El presente trabajo parte de la premisa de que el envejecimiento de la población es un fenómeno que hay que abordar desde las políticas públicas puesto que interroga a la sociedad en su conjunto y exige la responsabilidad de los Estados como garantes de los derechos de las personas mayores. Tales políticas deberán guiarse por los estándares y principios marcados por Naciones Unidas, el Consejo de Europa y la Unión Europea, que reclaman adoptar un enfoque basado en derechos Humanos y una atención integral centrada en la persona, como canales para articular un tratamiento adecuado de los derechos de las personas mayores, sin olvidar el compromiso ético de todos los agentes implicados en dar r…
Reflektoiva oppilas suomalaisessa perusopetuksen opetussuunnitelmallisessa arviointidiskurssissa
2023
Oppilaan itsearvioinnista on muotoutunut keskeinen osa arviointia suomalaisessa perusopetuksessa viime vuosikymmeninä, mutta oppilaalta on odotettu itsearviointia paljon tätä pidempään. Artikkelissa analysoidaan oppilaan itsearvioinnin historiaa suomalaisessa opetussuunnitelmapolitiikkadiskurssissa ja erityisesti sitä, miten itsearviointi on problematisoitunut eri tavoin ajan kuluessa. Tutkimuksessa hyödynnetään Carol Bacchin poststrukturalistiseen perinteeseen sijoittuvaa politiikkaongelmien rakentumista tarkastelevaa tutkimusstrategiaa ja analysoidaan suomalaisia oppivelvollisuuskoulun opetussuunnitelmia. Siinä missä kansakoulun aikana itsearviointi rakentui ratkaisuksi kriittisesti ajatt…
Il corpo, le emozioni e il riconoscimento reciproco
2019
This essay describes a phenomenology of the body and his language, the emotions. The main purpose is to highlight their referential scope. Emotions enable us to comprehend individual aspects partecipating in our lifeworlds. This perspective challanges today's dominant culture, where emotions are understood as mere self-expressions. Seen as favourable reactions to meeting the other, emotions appaear to us as forms of love and produce knowledge by dilection for the other's inner world. A reflection on the emotions, particulary empathy, highlights their impotance for the moral education to a correct sensibility.
SrP3N5O: a highly condensed layer phosphate structure solved from a nanocrystal by automated electron diffraction tomography.
2011
The oxonitridophosphate SrP(3)N(5)O has been synthesized by heating a multicomponent reactant mixture that consisted of phosphoryl triamide OP(NH(2))(3), thiophosphoryl triamide SP(NH(2))(3), SrS, and NH(4)Cl enclosed in evacuated and sealed silica-glass ampoules up to 750 °C. The compound was obtained as nanocrystalline powder with needle-shaped crystallites. The crystal structure was solved ab initio on the basis of electron diffraction data by means of automated electron diffraction tomography (ADT) and verified by Rietveld refinement with X-ray powder diffraction data. SrP(3)N(5)O crystallizes in the orthorhombic space group Pnma (no. 62) with unit-cell data of a=18.331(2), b=8.086(1), …
Surfactant-Mediated Morphology and Photocatalytic Activity of α‑Ag2WO4 Material
2018
In the present work, the morphology (hexagonal rod-like vs cuboid-like) of an α-Ag2WO4 solid-state material is manipulated by a simple controlled-precipitation method, with and without the presence of the anionic surfactant sodium dodecyl sulfate (SDS), respectively, over short reaction times. Characterization techniques, such as X-ray diffraction analysis, Rietveld refinement analysis, Fourier-transform (FT) infrared spectroscopy, FT Raman spectroscopy, UV–vis spectroscopy, transmission electron microscopy (TEM), high-resolution TEM, selected area electron diffraction, energy-dispersive X-ray spectroscopy, field emission-scanning electron microscopy (FE-SEM), and photoluminescence emission…
Children in the visual coverage of the European refugee crisis: A case study of the World Press Photo 2016
2018
Shifts in the visual coverage of refugees arriving in Europe and prominent compassion fatigue emphasize the need to examine visual strategies utilized to report on the crisis. This study focuses on representations of refugee children using a case of the World Press Photo (WPP) 2016. The material was interpreted with a model for visual rhetorical interpretation of journalistic photographs. Findings indicate the main visual elements involved in representing refugee children: visual trope of the migrant father, relation between children and barriers, visual oxymoron (juxtaposition of contradictory elements) and atmosphere in photographs. Findings suggest that photographs address polemics speci…
Photocatalytic H2 evolution from aqueous solutions of oxygenated organic compounds in the presence of C3N4/reduced graphene oxide based photocatalysts
2022
Composites of C3N4/reduced graphene oxide have been used as a cheap and promising photocatalysts for triethanolamine and ethanol photo-reforming with H2 generation in aqueous solution. The rate of H2 production over the best performing photocatalysts reached 1,415 μmol·h-1·g-1 which increases up to 57,306 in the presence of 1% of Pt. The apparent quantum efficiency of the optimal material was 7 % by using both LED and natural sunlight irradiation
Photocatalytic Generation of H2 by Photoreforming of Organics in Aqueous Suspension of Nb2o5/C3n4 Composites
2023
Bare and composite materials based on C3N4 and Nb2O5 have been used as photocatalysts for the photoreforming of aqueous solutions of oxygenated compounds. Both Nb2O5 and Nb2O5/C3N4 composites have been prepared by hydrothermal synthesis and all of them were physical-chemically characterized. In this work two different carbon nitride species i.e. graphitic (g-C3N4) or thermo-etched (TE-C3N4) were used both alone or coupled with Nb2O5. The photo-reforming activity has been measured under UV irradiation by using the semiconductors in the presence of Pt as co-catalysts and, in the case of the best material, it was, for the first time, measured and compared also under natural solar irradiation. …
Problem-Based Learning in Professional Studies from the Physiotherapy Students’ Perspective
2018
The aim of the study was to investigate how physiotherapy students using a problem-based learning approach develop into experts during higher education, and answers the question: How do physiotherapy students at bachelor’s level understand the problem-based learning approach while learning to become professionals? PBL is examined using interpretative phenomenological analysis (IPA) of longitudinal data written by 15 voluntary students from two different higher education institutions and collected during 3.5 years. The main results on the new way of learning strengthen earlier conceptions of the importance of reflection in the learning process. The PBL method activates a reflection process b…
