Pirmsskolas vecuma bērnu māšu apzinātības saistība ar bērnu temperamentu un uzvedības problēmām
2021
Pētījuma mērķis bija atklāt, kādas saistības pastāv starp pirmsskolas vecuma bērnu māšu apzinātību, bērnu temperamentu un uzvedības problēmām, kā arī, cik lielā mērā mātes apzinātības līmenis un bērna temperamenta dimensijas izskaidro bērna internalizētās un eksternalizētās uzvedības problēmas. Pētījumā piedalījās 137 pirmsskolas vecuma bērnu mātes, kuras šobrīd audzina vienu vai vairākus bērnus vecumā no 5 līdz 6 gadiem (51,1% zēni; 48,9% meitenes). Pētījumā tika izmantotas Bērnu temperamenta aptauja (ļoti īsā forma), (Very Short Form of the Children’s Behavior Questionnaire), Pirmsskolas vecuma bērnu uzvedības novērtējuma anketas (1,5-5 gadi) vecāku forma (Child Behavior Checklist 1 ½ - 5…
FIB-FESEM and EMPA results on Antoninianus silver coins for manufacturing and corrosion processes
2018
[EN] A set of ancient Antoninianus silver coins, dating back between 249 and 274¿A.D. and minted in Rome, Galliae, Orient and Ticinum, have been characterized. We use, for the first time, a combination of nano-invasive (focused ion beam-field emission scanning electron microscopy-X-ray microanalysis (FIB-FESEM-EDX), voltammetry of microparticles (VIMP)) and destructive techniques (scanning electron microscopy (SEM-EDX) and electron microprobe analysis (EMPA)) along with non-invasive, i.e., micro-Raman spectroscopy. The results revealed that, contrary to the extended belief, a complex Ag-Cu-Pb-Sn alloy was used. The use of alloys was common in the flourishing years of the Roman Empire. In th…
Reading data from graphs: a study on the role of language.
2015
International audience; The work described in this paper is framed in a larger study focused on written argumentations produced by university students in tasks regarding graphs, conversions between graphs and their analytic properties and relations among different graphs. Using the functional linguistics framework, we analyse difficulties related to an examination task on functions and their derivatives. The use of colloquial and literate registers in mathematics problem solving is the lens through which we analyse and discuss the errors. We draw attention to the difficulties concerning the use of literate registers and how these difficulties influence the errors in the interpretations of t…
Problem Solving and Argumentative Skills in Multicultural Italian Classrooms.
2016
In the last decades the population in Italian classrooms has become increasing more multicultural. Even if the law guarantees to all students the access to school, the gap between Italian students and migrant ones is becoming more and more evident in the results of national surveys in Italian Language and Mathematics and in the high dropout rates. A preliminary investigation was carried out to highlight the main difficulties faced in mathematics by these students, particularly related to problem solving and argumentation. The research aimed therefore to the development and testing of an educational intervention that, taking into account cultural and linguistic differences, aims at strengthe…
Hydrophobic interactions between aroma compounds and beta-Lactoglobulin using a specific fluorescent probe and NMR
2008
International audience; Many aroma compounds are known to bind with proteins, and elucidating these bindind interactions is a key in a better knowledgment of flavour perception mechanisms (1). beta-Lactoglobulin (bLg), the major whey protein of milk, has been used as a model food protein in numerous studies. Previous work have shown different binding sites on bLg for aroma compounds as a function of their chemical class, and emphasized the importance of hydrophobic interactions (2). (...)
Ars amandi et reprobatio amoris : trois formules de l’amour médiéval
2000
Ars amatoria y su Reprobatio amoris, fueron fuente inagotable de innumerables textos medievales y renacentistas, pero sobre todo el que cualquier poeta los conociera al pie de la letra, y lo que es más curioso aún, que queden tantos ejemplares valiosos en toda Europa.

Uzvedības problēmu, mērījumu un intervenču analīze, plānojot ieviest Labās Uzvedības Spēli skolā
2020
Maģistra darba mērķis bija sistemātiski analizēt un apkopot pasaulē līdz šim veikto pētījumu metodes un rezultātus par klasē balstītas atbalsta programmas ietekmi pozitīvas uzvedības veicināšanai un nevēlamas uzvedības mazināšanai skolas vecuma bērniem. Vispirms darbā tiek apskatītas uzvedības problēmu izpausmes, pievēršot uzmanību uzvedības mērīšanai pētniecībā. Vēlāk tiek skaidrotas atbalsta programmas nevēlamai uzvedībai, akcentu liekot uz Labās Uzvedības Spēli (The Good Behavior Game, GBG). Šajā darbā aprakstītie pētījumi sniedz ieskatu Labās Uzvedības Spēles īstermiņa un ilgtermiņa efektivitātē. Tāpat arī tiek uzrunāti jautājumi, kuriem būtu jāpievērš uzmanība, plānojot ieviest jaunu u…
Succinobucol's New Coat - Conjugation with Steroids to Alter Its Drug Effect and Bioavailability
2011
Synthesis, detailed structural characterization (X-ray, NMR, MS, IR, elemental analysis), and studies of toxicity, antioxidant activity and bioavailability of unique potent anti-atherosclerotic succinobucol-steroid conjugates are reported. The conjugates consist of, on one side, the therapeutically important drug succinobucol ([4-{2,6-di-tert-butyl-4-[(1-{[3-tert-butyl-4-hydroxy-5-(propan-2-yl)phenyl]sulfanyl}ethyl)sulfanyl]phenoxy}-4-oxo-butanoic acid]) possessing an antioxidant and anti-inflammatory activity, and on the other side, plant stanol/sterols (stigmastanol, β-sitosterol and stigmasterol) possessing an ability to lower the blood cholesterol level. A cholesterol-succinobucol prodr…
