Inovação pedagógica e ortodoxia curricular

A partir de uma conceção de currículo em sentido lato, e tendo como referência acontecimentos recentes ocorridos em Portugal, o artigo discute a impossibilidade de o currículo poder constituir-se em fonte de transgressão, assumindo-se, pelo contrário, como fonte de mesmice e de ortodoxia. Além disso, rejeita também a possibilidade de inovação curricular e inovação pedagógica serem expressões sinónimas e de que a operacionalização do currículo na escola através das práticas (docentes) de desenvolvimento curricular possa equivaler ou conduzir a inovação curricular. Em oposição, relaciona inovação pedagógica e heterodoxia, cuja probabilidade é muito maior fora do espaço colonizado pelo currículo da escola.

La crítica secular en la enseñanza de la literatura: un puente para conectar las letras con las experiencias humanas, las realidades sociales y las instituciones de poder

Recibido 05 de mayo de 2010 • Aceptado 24 de junio de 2010 • Corregido 05 de agosto de 2010      Resumen. Con base en el aporte del crítico literario y pensador palestino Said (1983), quien acuña el término “crítica secular,” este artículo analiza la posibilidad de aplicar dicho concepto a la enseñanza de la literatura, tanto en niveles de educación primaria y secundaria, como en niveles superiores. Por crítica secular se debe entender el modo de análisis textual que ve a la literatura inherentemente ligada a las experiencias humanas, a las realidades sociales de los contextos en que es producida y a las instituciones de poder que la propician o la reprimen. La principal propuesta será, entonces, el plantear una metodología para abordar, en el salón de clase, los textos literarios desde una perspectiva mundana; es decir, ligándolos al mundo exterior, al que está fuera de las aulas. En este sentido, y utilizando tanto ejemplos textuales primarios como teoría literaria, el artículo propondrá convertir el estudio de la literatura en una herramienta de análisis, cuestionamiento, desafío y cambio de las realidades que la producen.

The Experience of Adult Literacy as a Learning Process in the Formation of Future Educators

Learning is constructed when it is significant, therefore, promoting experiences that can make sense and joy, which constitutes a challenge in the formation of future educators. In this article, we share the considerations emanated from an investigation that gathers the experience of alphabetizing adults, carried out by college students as part of their formation. As a result, this creates a learning process that favors the respect to diversity and the value of reading and writing as the liberation of mankind. The work displays the learnings constructed, the ways of respecting diversity that emerge from the alphabetizing experience, and the value that the students give to reading and writing as a liberating way of expression.

Ad summum bonum iter: revisione testuale e commento di Seneca, Epistulae morales ad Lucilium XLVIII, CXI.

Questa tesi di dottorato “Ad summum bonum iter. Revisione testuale e commento di Seneca, Epistulae morales ad Lucilium XLVIII, CXI” (relatore Prof. F. Citti), si propone di fornire un commento scientifico al testo latino di alcune Epistulae morales ad Lucilium (48 e 111), corredato da traduzione, note esegetiche di carattere lessicale, stilistico-retorico e storico-letterario e discussione delle principali problematiche testuali (testo di riferimento l'edizione critica di Reynolds, Oxonii 1965). Scopo della ricerca è approfondire e completare lo studio delle lettere 48 e 111 del carteggio, esaminato solo episodicamente e non sistematicamente, soffermandosi sugli aspetti filosofici salienti e sui motivi conduttori più significativi, come la critica senecana alla nimia subtilitas (tema presente soprattutto nelle cosiddette epistole dialettiche, connesse alle diverse forme di sillogismi e alle modalità di contestazione degli stessi), con particolare riferimento alle ambiguità derivanti dall'uso di termini in senso proprio e metalinguistico riflessivo e non riflessivo; la ricerca si sofferma inoltre sul linguaggio colloquiale, vicino a quello della commedia e della satira, utilizzato da Seneca per ridicolizzare i sillogismi stoici; sul tema dell'amicizia; sull'uso di citazioni e/o allusioni poetiche (virgiliana e non virgiliana), decontestualizzate e risemantizzate in funzione educativa e psicagogica, piegate ad esprimere il personale messaggio etico; sull'uso del lessico specialistico, proveniente da diversi ambiti semantici (giuridico, economico, militare, medico), applicato da Seneca alla parenesi filosofica e, soprattutto, sul rapporto tra lessico filosofico latino e modelli greci. Infine, oltre ad approfondire il motivo delle egestas temporis e i riferimenti diatribici contenuti nelle epistole, sono stati individuati e approfonditi alcuni topoi presenti.

Development of numerical methodologies to predict the liquid fuel sprays - wall interaction to optimize the mixing process of direct injection spark ignition engines

Nowadays the development of new Internal Combustion Engines is mainly driven by the need to reduce tailpipe emissions of pollutants, Green-House Gases and avoid the fossil fuels wasting. The design of dimension and shape of the combustion chamber together with the implementation of different injection strategies e.g., injection timing, spray targeting, higher injection pressure, play a key role in the accomplishment of the aforementioned targets. As far as the match between the fuel injection and evaporation and the combustion chamber shape is concerned, the assessment of the interaction between the liquid fuel spray and the engine walls in gasoline direct injection engines is crucial. The use of numerical simulations is an acknowledged technique to support the study of new technological solutions such as the design of new gasoline blends and of tailored injection strategies to pursue the target mixture formation. The current simulation framework lacks a well-defined best practice for the liquid fuel spray interaction simulation, which is a complex multi-physics problem. This thesis deals with the development of robust methodologies to approach the numerical simulation of the liquid fuel spray interaction with walls and lubricants. The accomplishment of this task was divided into three tasks: i) setup and validation of spray-wall impingement three-dimensional CFD spray simulations; ii) development of a one-dimensional model describing the liquid fuel – lubricant oil interaction; iii) development of a machine learning based algorithm aimed to define which mixture of known pure components mimics the physical behaviour of the real gasoline for the simulation of the liquid fuel spray interaction.

Transcreation: teoria e pratica dell’adattamento di campagne pubblicitarie globali

This dissertation explores the practice of transcreation as a consulting service aimed at companies wishing to enter the global market. Since a universally accepted definition of such term does not exist, different players use it to refer to different activities. In an attempt to investigate the meaning and scope of transcreation, as well as the skillset it requires, this dissertation consists of a theoretical part (Chapters 1 and 2) and a practical part (Chapter 3). The first chapter presents the opinions of academics, language services providers (LSPs) and transcreation experts. The different positions collected in this section are compared and discussed in order to better define transcreation and avoid any further misunderstanding about the practice. Lastly, the first chapter analyses the role of the transcreation expert by explaining in detail the four main skills it requires and the reasons for its increasing importance in the global market. The second chapter examines advertising and promotional materials, i.e. the kinds of texts to which transcreation applies. Not only does it illustrate the difference between above-the-line and below-the-line communications, but it also covers the different media used in advertising. In addition, the analysis of a billboard and two web pages in their Italian transcreation will help to further clarify the difference between translation and transcreation, both in the approach to a text and in the actual workflow followed. The third and final chapter of the dissertation, which entails the English to Italian transcreation of five different print ads performed by this author, aims to show how transcreation works in practice. By highlighting the main strategies used and difficulties encountered, it will also contribute to the notion of transcreation as a hybrid practice – something halfway between translation and copywriting, performed by professionals who possess the skills of both translators and copywriters.

Sviluppo di un sistema di Realta Aumentata applicato a un modello 3D della prostata, sviluppato a partire da immagini RM, al fine di facilitare la dissezione del tumore e la conservazione dei fasci neuro vascolari durante l'intervento chirurgico di prostatectomia radicale robot-assistita

La realtà aumentata (AR) è una nuova tecnologia adottata in chirurgia prostatica con l'obiettivo di migliorare la conservazione dei fasci neurovascolari (NVB) ed evitare i margini chirurgici positivi (PSM). Abbiamo arruolato prospetticamente pazienti con diagnosi di cancro alla prostata (PCa) sul base di biopsia di fusione mirata con mpMRI positiva. Prima dell'intervento, i pazienti arruolati sono stati indirizzati a sottoporsi a ricostruzione del modello virtuale 3D basato su mpMRI preoperatoria immagini. Infine, il chirurgo ha eseguito la RARP con l'ausilio del modello 3D proiettato in AR all'interno della console robotica (RARP guidata AR-3D). I pazienti sottoposti a AR RARP sono stati confrontati con quelli sottoposti a "RARP standard" nello stesso periodo. Nel complesso, i tassi di PSM erano comparabili tra i due gruppi; I PSM a livello della lesione indice erano significativamente più bassi nei pazienti riferiti al gruppo AR-3D (5%) rispetto a quelli nel gruppo di controllo (20%; p = 0,01). La nuova tecnica di guida AR-3D per l'analisi IFS può consentono di ridurre i PSM a livello della lesione dell'indice

Data sensitivity detection in chat interactions for privacy protection

In recent years, there has been exponential growth in using virtual spaces, including dialogue systems, that handle personal information. The concept of personal privacy in the literature is discussed and controversial, whereas, in the technological field, it directly influences the degree of reliability perceived in the information system (privacy ‘as trust’). This work aims to protect the right to privacy on personal data (GDPR, 2018) and avoid the loss of sensitive content by exploring sensitive information detection (SID) task. It is grounded on the following research questions: (RQ1) What does sensitive data mean? How to define a personal sensitive information domain? (RQ2) How to create a state-of-the-art model for SID?(RQ3) How to evaluate the model? RQ1 theoretically investigates the concepts of privacy and the ontological state-of-the-art representation of personal information. The Data Privacy Vocabulary (DPV) is the taxonomic resource taken as an authoritative reference for the definition of the knowledge domain. Concerning RQ2, we investigate two approaches to classify sensitive data: the first - bottom-up - explores automatic learning methods based on transformer networks, the second - top-down - proposes logical-symbolic methods with the construction of privaframe, a knowledge graph of compositional frames representing personal data categories. Both approaches are tested. For the evaluation - RQ3 – we create SPeDaC, a sentence-level labeled resource. This can be used as a benchmark or training in the SID task, filling the gap of a shared resource in this field. If the approach based on artificial neural networks confirms the validity of the direction adopted in the most recent studies on SID, the logical-symbolic approach emerges as the preferred way for the classification of fine-grained personal data categories, thanks to the semantic-grounded tailor modeling it allows. At the same time, the results highlight the strong potential of hybrid architectures in solving automatic tasks.

Trajectory Planning in UAV-Aided Wireless Networks Via Reinforcement Learning

This thesis is focused on the design of a flexible, dynamic and innovative telecommunication's system for future 6G applications on vehicular communications. The system is based on the development of drones acting as mobile base stations in an urban scenario to cope with the increasing traffic demand and avoid network's congestion conditions. In particular, the exploitation of Reinforcement Learning algorithms is used to let the drone learn autonomously how to behave in a scenario full of obstacles with the goal of tracking and serve the maximum number of moving vehicles, by at the same time, minimizing the energy consumed to perform its tasks. This project is an extraordinary opportunity to open the doors to a new way of applying and develop telecommunications in an urban scenario by mixing it to the rising world of the Artificial Intelligence.

Do Larvae and Ovipositing Chironomus riparius (Diptera: Chironomidae) Females Avoid Copper-Contaminated Environments?

Studies on the avoidance behavior of aquatic organisms to contaminants have confirmed that such behavior can be relevant in field situations. However, almost all toxicity tests involve the forced exposure of organisms to toxicants. In particular, despite the importance of Chironomus riparius Meigen larvae in sediment toxicity testing, only a few studies on avoidance behavior have been performed. This study investigated the ability of different life stages of C. riparius, including ovipositing females, first-, second-, and fourth-instar larvae, to avoid copper-contaminated environments. Ovipositing females were given a choice between a control and copper solution (1.3 mg Cu l(-1)). First-instar larvae were provided with a choice between a control and a copper (2.0 mg Cu l(-1))-spiked sediment. Both second- and fourth-instars were exposed to a copper gradient (0.38-3.4 mg Cu l(-1)) in a flow-through system. None of the life stages avoided copper, even though the highest concentrations caused lethal effects on midges. The avoidance behavior of C. riparius is not a sensitive endpoint to assess copper sublethal toxicity.
