On velocity-dependent dark matter annihilations in dwarf satellites
Mauro Valli, Piero Ullio, Mihael Petač, 2018, original scientific article

Abstract: Milky Way dwarf spheroidal satellites are a prime target for Dark Matter (DM) indirect searches. There have been recent reassessments of the expected DM gamma-ray signals in case of long-range interactions, commonly known as Sommerfeld enhancement. Since details of the underlying DM phase-space distribution function become critical, there are potentially large uncertainties in the final result. We provide here a first attempt towards a comprehensive investigation of these systematics, addressing the impact on the expected DM flux from Milky Way dwarfs via Bayesian inference on the available stellar kinematic datasets. After reconsidering the study case of ergodic systems, we investigate for the first time scenarios where DM particle orbits may have a radial or tangential bias. We consider both cuspy and cored parametric DM density profiles, together with the case of a non-parametric halo modelling directly connected to line-of-sight observable quantities. The main findings of our work highlight the relevance of the assumed phase-space distribution: Referring to a generalized J-factor, namely the line-of-sight convolution of the spatial part in case of velocity-dependent annihilation rate, an enhancement (suppression) with respect to the limit of isotropic phase-space distributions is obtained for the case of tangentially (radially) biased DM particle orbits. We provide new estimates for J-factors for the eight brightest Milky Way dwarfs also in the limit of velocity-independent DM annihilation, in good agreement with previous results in literature, and derive data-driven lower-bounds based on the non-parametric modelling of the halo density. The outcome of our broad study stands out as a representative of the state-of-the-art in the field, and falls within the interest of current and future experimental collaborations involved in DM indirect detection programs.

Identification of environmental stress conditions by comparative analysis of peroxidase activity in betulla pendula and pinus sp.
Kenan Kapetanović, Hena Zukić, Miroslav Štrbac, Darian Rampih, Katarina Erker, Nina Žvab-Pernat, Patrik Cingerli, 2021, treatise, preliminary study, study

Abstract: The study investigated the possibility of developing a biomarker to evaluate the stress level in trees. The analyses have been performed on tree samples appertaining to two different tree species and collected at two locations in Slovenia. The presence and the activity of the proteins – peroxidases was measured by the qualitative method of the agarose gel electrophoresis and the quantitative method of spectrometry. It was found out that by measuring the presence of the biomarkers and pigments in the tree samples we can determine the stress levels and thus the health status of trees.

Šolanje v šolah s slovenskim učnim jezikom v Italiji v času pouka na daljavo
Maja Melinc Mlekuž, 2021, published scientific conference contribution abstract

Abstract: Analiza polstrukturiranih globinskih intervjujev med učitelji in starši otrok, ki obiskujejo osnovno šolo s slovenskim učnim jezikom in slovensko-italijanskim dvojezičnim poukom v Italiji, prinaša vpogled v didaktično-metodične izzive pri poučevanju učencev na daljavo, katerih prvi ali primarni jezik ni slovenski, slovenščina pa tudi ni jezik okolja, v katerem živijo. V vzgojno-izobraževalnih ustanovah s slovenskim učnim jezikom, od vrtcev do drugostopenjskih srednjih šol, je namreč veliko otrok iz neslovensko govorečih družin, kar prinaša večje število potencialnih govorcev slovenščine, številčnejše razrede ter integracijo slovenske narodne manjšinez večinskim prebivalstvom, hkrati pa tudi metodične prilagoditve za doseganje temeljnih učnih ciljev za pouk slovenščine kot J1, pa čeprav je slovenščina za učence J2.

The theory of mind's role in pronoun acquisition
Greta Mazzaggio, 2016, original scientific article

Abstract: This study’s aim is to understand how children learn first- and second-person singular pronouns. Many researchers tried to find possible connection between Theory of Mind (ToM) and the acquisition of pronouns. The ability to produce and comprehend first- and second-person singular pronouns seems closely linked with the ability to appreciate other people’s mental states: a lack or non-mature development of ToM may thus affect their competence in using pronouns. To strengthen this hypothesis we focused on the phenomenon of pronoun reversal, which mainly consists in the substitution of I for you, and you for I, testing a group of 17 typically developing children - 38 to 70 months of age. Due to its pro-drop classification, Italian is the focus language of this study. The outcome showed a correlation between the phenomena of ToM and pronoun reversal. Further research should focus on the directionality of this correlation and better our understanding of its meaning.
