Theoretical and experimental aspects of numerosity and quantification in Lebanese Arabic
Ali Al Moussaoui, 2021, doktorska disertacija

Opis: A question that is receiving an increasing attention in linguistics research concerns the language components of counting. This topic is approached from syntactic, semantic and pragmatic points of view. While some accounts advocate for purely syntactic or semantic approaches of countability, other adopt hybrid accounts in which labor is divided between syntax and semantics. At the same time, research finds that there is a pragmatic component enriching the interpretation of countability and numerosity in language. This dissertation attempts to contribute into the lines of research concerned in the syntactic, semantic and pragmatic aspects of countability with a focus on Lebanese Arabic (Henceforth LA), a language that has received little attention in the literature of counting. In this dissertation, a broken agreement pattern in LA between the cardinal numerals and the post-numeral counted noun phrases is examined on the basis of a syntactic-semantic model of countability developed by Stepanov and Stateva (2018). We argue that the current existing model can be used to account for the countability broken agreement pattern in LA when necessary modifications are applied to it. The success of this model in accounting for the numeral-noun-phrase agreement in LA is added to its success in similar missions in countability in Russian (Stepanov and Stateva 2018) and previously in Japanese (Watanabe 2010). The pragmatic component of countability in LA is also examined from the angle of pragmatic strengthening. The traditional difference between singular nominals and plural nominals which makes a distinction between domains of atoms and domains of sums is seriously challenged by current semantic and pragmatic research. The plural is found to be more complex than a simplistic view of more than one, and its interpretation has a pragmatic component which involves enriching the meaning of plurality against singularity. In our dissertation, we intend to examine an enriching pragmatic process of plural against duality in LA, a language that still preserves special morphological marking for duality. So, our research investigates the pragmatic strengthening of the plural morphology in LA against the dual morphology which results in at-least-three meaning of the plural. On the assumption that pragmatic reasoning contributes to the interpretation of plural nominals, we extend our research to the area of bilingual LA speakers who can be an ideal environment to look into the cognitive processes involved in the interaction between two linguistic systems that have diverging features pertaining to a given linguistic phenomenon, which is countability in our study. We predict crosslinguistic variation in the interpretation of plural morphology. If languages like English associate plural with an at-least-two meaning as a result of pragmatic enrichment with an anti-singularity inference, then, in languages that morphologically differentiate among singular, plural and dual number, the morphological plural is predicted to correspond to an at-least-three meaning. In this study, we ask whether the predicted variation in the interpretation of plural morphology among the non-dual and dual-featuring languages is a locus of negative pragmatic transfer of features from LA as a mother tongue and English/ French as foreign languages.

Combined effects of early season leaf removal and climatic conditions on aroma precursors in ‘Sauvignon blanc’ grapes
Andreja Vanzo, Paolo SABBATINI, Klemen Lisjak, Marijan Bubola, Melita Sternad Lemut, Lorena Butinar, Branka Škvarč, Jose Carlos HERRERA, Rachele FALCHI, Paolo Sivilotti, 2017, izvirni znanstveni članek

Opis: Early leaf removal around the cluster zone is a common technique applied in cool climate viticulture, to regulate yield components and improve fruit quality. Despite the increasing amount of information on early leaf removal and its impact on total soluble solids, anthocyanins and polyphenols, less is known regarding aroma compounds. In order to verify the hypothesis that defoliation, applied before or after flowering, could impact the biosynthesis of thiol precursors, we performed a two year (2013 and 2014) experiment on Sauvignon blanc. We provided evidence that differential accumulation of thiols precursors in berries is affected by the timing of defoliation and this impact was related to modifications in biosynthetic pathway. Furthermore, the possible interaction between leaf removal treatment and seasonal weather conditions, and its effect on the biosynthesis of volatile precursors are discussed. Our results suggested that in Sauvignon blanc the relative proportion of 4-S-glutathionyl-4-methylpentan-2-one (G-4MSP) and 3-S-glutathionylhexan-1-ol (G-3SH) precursors can be affected by defoliation, and this could be related to the induction of two specific genes encoding glutathione-S-transferases (VvGST3 and VvGST5), while no significant effects on basic fruit chemical parameters, polyphenols and methoxypyrazines were ascertained under our experimental conditions.

Portrait of light
Marco Pelos Spagno, 2017, diplomsko delo

Opis: This work aims to research the basic structure of lighting in portraits in a controlled light situation. After providing a brief historical introduction to define where modern lighting comes from, I will describe and analyse the tools used to modify the light in a studio and the procedure to follow before a portrait session. I will present a series of images shot in a studio, and I will touch upon most possible basic lighting setups in a portrait session, from most simple ones to some more complex ones, describing the set of lights, the type of modifiers used, and the effects that the light can have on a viewer. My final aim is to build up a collection of light setups that can be helpful to anyone who wants to approach portrait photography and the studio workflow, not aiming to build a manual, but just providing a report on my personal research and study.

Physiological responses of garden cress (L. sativum) to different types of microplastics
Sara Pignattelli, Andrea Broccoli, Monia Renzi, 2020, izvirni znanstveni članek

Opis: In this study, for the first time, acute and chronic toxicity caused by four different kinds of microplastics: polypropylene (PP), polyethylene (PE), polyvinylchloride (PVC), and a commercial mixture (PE + PVC) on Lepidium sativum were evaluated. Parameters considered were: i) biometric parameters (e.g. percentage inhibition of seed germination, plant height, leaf number and fresh biomass productions); and ii) oxidative stress (e.g. levels of hydrogen peroxide, glutathione, and ascorbic acid). On plants exposed to chronic stress chlorophylls, carotenoids, aminolaevulinic acid, and proline productions were, also, evaluated. PVC resulted the most toxic than other plastic materials tested. This study represents the first paper highlighting microplastics are able to produce oxidative burst in tested plants and could represent an important starting point for future researches on biochemical effects of microplastic in terrestrial environments such as agroecosystems.
