Daudzdimensionālas personības aptaujas izstrāde un validizācija Latvijas pieaugušo izlasē
2014
Promocijas darba: Daudzdimensionālas personības aptaujas izstrāde un validizācija Latvijas pieaugušo izlasē Anotācija Promocijas darba ietvaros triju empīrisko pētījumu rezultātā tika izstrādāts daudzdimensionāls personības mērījuma instruments - Latvijas Personības aptauja (LPA-v3). Ar tās palīdzību var novērtēt sešus plašus personības faktorus: neirotismu, ekstraversiju, apzinīgumu, labvēlīgumu, atvērtību pieredzei un godīgumu-pieticību un četras personības iezīmes katrā faktora ietvaros. LPA-v3 uzrāda augstu iekšējas saskaņotības un retesta ticamību personības faktoru līmenī un apmierinošu līdz labu ticamību – apakšskalu līmenī. Ir apstiprināta LPA-v3 validitāte, ieskaitot faktoriālo val…
A new picking algorithm based on the variance piecewise constant models
2022
AbstractIn this paper, we propose a novel picking algorithm for the automatic P- and S-waves onset time determination. Our algorithm is based on the variance piecewise constant models of the earthquake waveforms. The effectiveness and robustness of our picking algorithm are tested both on synthetic seismograms and real data. We simulate seismic events with different magnitudes (between 2 and 5) recorded at different epicentral distances (between 10 and 250 km). For the application to real data, we analyse waveforms from the seismic sequence of L’Aquila (Italy), in 2009. The obtained results are compared with those obtained by the application of the classic STA/LTA picking algorithm. Althoug…
Teenage Violence Toward Parents – in Search of the Theoretical Bases of a Research Tool
2020
The article contains an analysis of results of the available research on the phenomenon of children’s violence toward their parents. The main purpose of this interpretation is to search for the theoretical structure of a prepared research tool, initially called the Teen Violence Scale Toward Parents (TVSTP). The subject of the analyzes were works and research reports as well as police statistics containing information on the phenomenon of domestic violence, including teenage violence toward parents. As a result of the analysis, the theoretical function of the proposed research tool was distinguished, referring to types of violence possible to diagnose within this area. The proposed tool was…
