Does Grammatical Structure Accelerate Number Word Learning? Evidence from Learners of Dual and Non-Dual Dialects of Slovenian
Franc Marušič, Rok Žaucer, Vesna Plesničar, Tina Razboršek, Jessica Sullivan, David Barner, 2016, original scientific article

Abstract: How does linguistic structure affect children’s acquisition of early number word meanings? Previous studies have tested this question by comparing how children learning languages with different grammatical representations of number learn the meanings of labels for small numbers, like 1, 2, and 3. For example, children who acquire a language with singular-plural marking, like English, are faster to learn the word for 1 than children learning a language that lacks the singular-plural distinction, perhaps because the word for 1 is always used in singular contexts, highlighting its meaning. These studies are problematic, however, because reported differences in number word learning may be due to unmeasured cross-cultural differences rather than specific linguistic differences. To address this problem, we investigated number word learning in four groups of children from a single culture who spoke different dialects of the same language that differed chiefly with respect to how they grammatically mark number. We found that learning a dialect which features “dual” morphology (marking of pairs) accelerated children’s acquisition of the number word two relative to learning a “non-dual” dialect of the same language.

Primerjava metod večparametrskega odločanja pri izbiri tehnologije spajkanja
David Rejc, 2016, master's thesis

Abstract: V magistrskem delu obravnavamo večparametrske odločitvene metode, ki se med seboj razlikujejo po načinu vrednotenja parametrov. Primarni cilj magistrskega dela je medsebojno primerjati odločitvene modele, razvite z različnimi metodami večparametrskega modeliranja. Sekundarni cilj je bil z odločitvenimi modeli vrednotiti, rangirati in analizirati alternativne tehnologije spajkanja fleksibilnega vezja in izbirati najboljšo alternativo. V prvem delu magistrskega dela predstavljamo družbi Hidria AET d. o. o. in SiEVA d. o. o. Predstavili smo trende v avtomobilski industriji in zahteve po razvoju avtomobilskih dizelskih motorjev z manjšo porabo goriva in nižjim izpustom škodljivih emisij. Predstavili smo razvoj svečke s senzorjem tlaka, ki je ključni del regulacije delovanja teh motorjev. Raziskali in predstavili smo tehnološke zahteve za avtomatizacijo procesa spajkanja fleksibilnega vezja. Identificirali smo odločitveni problem pri izbiri ustrezne tehnologije spajkanja, zaželene in nezaželene posledice odločitve in določili zahteve, ki jih morajo izpolnjevati alternative. Predstavili smo vse tri alternative: tehnologijo spajkanja z vročo kladico, infrardečo svetlobo in laserskim žarkom. V drugem delu magistrskega dela smo predstavili področje podpore odločanju in večparametrske odločitvene metode: APIS, PMI, Abacon, Kepner-Tregoe, EVAMIX, AHP in DEX. Z vsemi metodami smo razvili odločitvene modele in z njimi ocenili in rangirali alternative. Rezultate vrednotenja smo analizirali s "kaj-če" analizo. Izdelali smo sintezo rezultatov vrednotenja alternativ in na njeni osnovi primerjali odločitvene modele. Ugotavljamo, da smo z vsemi odločitvenimi metodami najvišje ocenili in rangirali tehnologijo spajkanja z vročo kladico, zato bomo odločevalcem svetovali njeno izbiro.

ECOLOGICAL STUDIES OF EPIKARST COMMUNITIES IN ALPINE AND PRE-ALPINE CAVES
Federica Papi, 2016, doctoral dissertation

Abstract: The karst ecosystem shows heterogeneity and variability of geology, hydrology, morphology and ecology in space and time. Chemical composition of water in karst plays a crucial role not only in dissolution of karst rocks and deposition but also in ecological processes. The heterogeneous nature of karst aquifers leads to difficulties in predicting groundwater flow and contaminant transport direction and travel times. For its position at the top of karst, epikarst represents the interface between surface and underground. Epikarst ecology, biodiversity and fauna have rarely been systematically studied. The typical absence of enterable passages makes necessary an indirect approach. In this research, epikarst biodiversity in relation to environmental conditions was studied in seven Alpine and Pre-Alpine caves, located at different altitudes, in Slovenia and in Italy: Snežna jama na planini Arto (1556 m a.s.l.), Jama pod Babjim zobom (860 m a.s.l.), Zadlaška jama (300 m a.s.l.) and Pološka jama (500 m a.s.l.), in Slovenian Alps and Pre-alps, and Grotta A del Ponte di Veja (600 m a.s.l.), Covolo della Croce (875 m a.s.l.) and Grotta di Roverè Mille (1005 m a.s.l.) in Lessinian Massif. In these caves, percolating water was monthly monitored for fauna in the period of one year. Temperature, discharge, conductivity and pH were measured at the same time, and water samples for the laboratory analyses of total hardness, concentrations of various ions (calcium, chlorine, nitrate, sulphate and phosphate) and dissolved organic carbon were taken. 66 aquatic and terrestrial, mostly hypogean, species were found. Aquatic fauna was dominant in all caves, with the exception of Covolo della Croce. Caves located at higher elevations harbour less diverse communities. No animals were found when discharge was very low and in correspondence of moonmilk formations. The most abundant and diverse group was Copepoda, with thirteen different species and 776 individuals at different maturity stadia, totally representing 61% of the community (between two and three copepod species per cave in Slovenia and between one and six per cave in Italy). The 62% of copepod species were stygobionts. Some copepod species (e.g. Speocyclops infernus) have wide ecological tolerance to environmental variables, other have more restricted tolerances (e.g. Lessinocamptus insoletus). With regard of copepods, there was a good agreement between the number of observed species and the total number of predicted species, confirming that the sampling method was appropriate and sampling complete. Correlations between the copepod community structure and measured parameters, obtained with Pearson correlation coefficient and principal component analysis (PCA) show different patterns. Presence of copepods was positively correlated with conductivity and dissolved organic carbon in Grotta di Roverè Mille, and with carbonate and nitrate in Pološka jama. In other caves not so high correlations were found between copepod species and measured parameters and between pairs of species. Investigations of the Alpine and Pre-alpine epikarst fauna can help to understand better the ecology of the epikarst fauna and its roles within the large range of different shallow subterranean habitats.

Hexagonal lattice model of the patterns formed by hydrogen-bonded molecules on the surface
Sara Fortuna, David L. Cheung, Alessandro Troisi, 2010, original scientific article

Abstract: We model the two-dimensional self-assembly of planar molecules capable of complementary interactions (like hydrogen bonding) as a set of hexagonal tiles on a hexagonal lattice. We use Monte Carlo simulations to study the phase diagrams of three model systems. The phases are characterized using a variety of order parameters, and they are studied as a function of the strength of the complementary interaction energy. This simplified model is proven to be capable of reproducing the phases encountered in real systems, unifying within the same framework most of the structures encountered experimentally.

Polymer Vesicles with a Colloidal Armor of Nanoparticles
Rong Chen, Daniel J. G. Pearce, Sara Fortuna, David L. Cheung, Stefan A. F. Bon, 2011, original scientific article

Abstract: The fabrication of polymer vesicles with a colloidal armor made from a variety of nanoparticles is demonstrated. In addition, it is shown that the armored supracolloidal structure can be postmodified through film-formation of soft polymer latex particles on the surface of the polymersome, hereby effectively wrapping the polymersome in a plastic bag, as well as through formation of a hydrogel by disintegrating an assembled polymer latex made from poly(ethyl acrylate-co-methacrylic acid) upon increasing the pH. Furthermore, ordering and packing patterns are briefly addressed with the aid of Monte Carlo simulations, including patterns observed when polymersomes are exposed to a binary mixture of colloids of different size.
