Advanced monitoring and computational strategies for water quality assessment and CECs management
No full textContaminants of Emerging Concern or CECs encompass a wide range of natural and human-made substances, recently introduced into the environment or long-present but only recently recognized as widespread and potentially harmful. Detected at trace concentrations, they pose potential risks to the "One Health" triad: the environment, humans, and animals. To defuse the ticking ’timebomb’ of water pollution, it is essential to investigate the fate and transport of these contaminants in aquatic systems. This helps to unveil their potential reactivity and toxicity, and facilitates the development of new monitoring and
remediation strategies, that allow for continuous data collection and more effective risk management. In this context, the European Commission aims to protect the hydrosphere through continuous water monitoring and the digitalization of water
supply networks. The goal is to achieve a 30-50% reduction in the pollution of rivers and lakes by 2030. Starting from the premise that "Blue gold is not scarce, but the real problem is
our ability to use it", this dissertation aligns with the current objective, proposing two innovative electrochemical sensors: a "green" sensor for analyzing chemical oxygen demand (COD), a key parameter for assessing water quality, and another based on
methylene-blue gold nanoparticles, capable of detecting a class of CECs, namely per- and polyfluoroalkyl substances (PFAS) and anionic surfactants, at trace level concentrations. Current methods for detecting PFAS and CECs are based on liquid chromatography coupled with mass spectrometry. These methods are time-consuming and expensive; moreover, undesired adsorption of contaminants, specifically PFAS, to containers can lead to errors. The adsorption of PFAS to plastic containers suggests a higher interaction with nanoplastics and plastic debris in aquatic environments. To gain deeper insight into the behavior of these contaminants in water and to understand their "cocktail toxic effect", a new computational strategy was developed for elucidating the co-transport of PFAS and microplastics, another widespread class of CECs. Additionally, a chemical risk probabilistic model based on Bayesian statistic is proposed, which describes the risk exposure to PFAS along the wastewater treatment plant, thereby assisting in water management. Social implications, cost-benefit analysis, and the principles of the circular economy are integrated and evaluated in each aspect of this research
Electronic Dictionaries for Information Retrieval, Automatic Textual Analysis and Semantic-Based Data Mining Software applications
No full textToday Lexicon-Grammar (LG) remains one of the most consistent Natural Language Processing (NLP) approaches, especially for
Semantic-Based Data Mining (SBDM) and Semantic Web. Its main goal is to describe all mechanisms of word combinations closely related to the concrete use of lexical units and to sentence creation. Also, it gives an exhaustive description of lexical and syntactic structures of several languages. LG was set up by the French linguist Maurice Gross during the ‘60s, and subsequently developed for and applied to Italian by Annibale Elia, Emilio D’Agostino and Maurizio Martinelli. Its theoretical approach is prevalently based on Zelig Sabbettai Harris’ Operator-Argument Grammar, which assumes that each human language is a self-organizing system, and that the syntactic and semantic properties of a given word may be calculated on the basis of the relationships this word has with all other co-occurring words inside given sentence contexts. Simple sentences are the minimal linguistic meaning structures upon which LG founds its studies on natural language syntactic features. In the last twenty years, LG has also reached important results in the domain of automatic textual analysis and parsing with NLP-oriented software such as INTEX, UNITEX, and more recently NOOJ
L'arte del libro. Manuzio e il libro illustrato a Venezia tra Quattrocento e Cinquecento
No full textIl saggio indaga codici miniati e libri figurati veneziani del tempo di Aldo Manuzio, soffermandosi sull'importanza della miniatura e della xilografia come tramite di illustrazione di tematiche classiche. Vengono presi in considerazione codici del calligrafo Bartolomeo Sanvito che furono modelli per le aldine di Manuzio, miniati da artisti che seppero elaborare una versione tipicamente veneziana della cultura all'antica. L'indagine parte dai primi incunaboli miniati a Venezia da Girolamo da Cremona e si estende alla produzione più tarda in stile popolare e stile classico dove risultano protagonisti Benedetto Bordon e il Secondo Maestro del Grifo artisti ai quali è ricondotto il disegno delle xilografie dell'Hypnerotomachia Poliphili edita da Aldo nel 1499. L'intento è quello di osservare la continuità culturale formale e stilistica tra le opere veneziane del secondo quattrocento, manoscritte e a stampa, e la nuova proposta editoriale di Manuzio
A double-loop evaluation process for MOOC design and its pilot application in the university domain
No full textThe diffusion of Massive Open Online Courses (MOOCs) is significantly changing the way people learn and update their knowledge and competencies. Although the benefits characterizing MOOCs, which leverage on free and open access to know-how and digitized materials, there are some challenges which call for improving and enhancing the existing methods and approaches for MOOCs design. By combining theory and practice, this paper presents a process of MOOCs design based on a double-loop phase of evaluation. Specifically, the paper provides evidences on how to take advantage of the learners’ and teachers’ feedback to redesign or rethink the course’s architecture, and especially the storyboard and blueprint. A pilot application of the proposed approach has been made to design a course dealing with entrepreneurship domain, and in particular with crowdfunding. The results of the application are presented to validate the approach and provide teachers and course’s designers with some recommendations

paragraphs 3.1 and 4. Federica Marano is author of paragraphs 3.2 and 4.3. Johanna
Monti is author of sections 1 and 2. Antonella Napoli is author of paragraph 4.2.
2 In LG, a simple sentence is formed by a unique predicative element (a verb, but
also a name or an adjective) plus all the necessary arguments it selects to achieve
acceptability and grammaticality. The study of simple sentences is completed analyzing
the rules of co-occurrence and selection restriction, which are distributional and
transformational rules based on predicate syntactic-semantic properties.

CORONAE, STEPHANAI E DIADEMATA. MANUFATTI PER IL CAPO E SIMBOLI DEL POTERE FEMMINILE (DA LIVIA A ELIA ARIADNE)
No full textCoronae, stephanai e diademata sono gli attributi più evidenti nella ritrattistica femminile di età imperiale e si configurano non solo come gioielli, ma anche come veicolo di informazioni. Obiettivo del presente lavoro è dimostrare come tali manufatti siano significativi indizi del rango e della posizione delle donne della famiglia imperiale, poiché legati al titolo di Augusta e alla legittimazione del potere grazie al ruolo delle donne come madri. Attraverso lo studio di un campione di ritratti pertinenti alla statuaria, alla glittica e alla numismatica, si propone una tipologia degli attributi e si affronta la loro analisi in relazione ai singoli soggetti, alle diverse dinastie e ai contesti in cui sono utilizzati. La ricerca ha sviluppo diacronico e copre il periodo compreso fra Livia ed Elia Ariadne.Coronae, stephanai and diademata are the clearest feautures in Roman female portraiture and they emerge not only as jewels, but also as a way to convey information. Aim of this work is to demonstrate how these artifacts are substantial clues to understand roles and positions of the female part of Roman Imperial families, since they are connected to the title of Augusta and to the dynastic legitimacy, thanks to female role as mothers of emperors. A catalogue of portraits from statuary, glyptic and numismatic leads to a tipology of these objects and to their analysis regarding single persons, dynasties and backgrounds. The study goes from Livia to Aelia Ariadne
