Biometanazione della frazione organica di rifiuti solidi urbani da raccolta indifferenziata mediante codigestione con refluo zootecnico o addizione di solfuro di sodio

Il presente elaborato è stato finalizzato allo sviluppo di un processo di digestione anaerobica della frazione organica dei rifiuti solidi urbani (FORSU oppure, in lingua inglese OFMSW, Organic Fraction of Municipal Solid Waste) provenienti da raccolta indifferenziata e conseguente produzione di biogas da impiegarsi per il recupero energetico. Questo lavoro rientra nell’ambito di un progetto, cofinanziato dalla Regione Emilia Romagna attraverso il Programma Regionale per la Ricerca Industriale, l’Innovazione e il Trasferimento Tecnologico (PRRIITT), sviluppato dal Dipartimento di Chimica Applicata e Scienza dei Materiali (DICASM) dell’Università di Bologna in collaborazione con la Facoltà di Ingegneria dell’Università di Ferrara e con la società Recupera s.r.l. che applicherà il processo nell’impianto pilota realizzato presso il proprio sito di biostabilizzazione e compostaggio ad Ostellato (FE). L’obiettivo è stato la verifica della possibilità di impiegare la frazione organica dei rifiuti indifferenziati per la produzione di biogas, e in particolare di metano, attraverso un processo di digestione anaerobica previo trattamento chimico oppure in codigestione con altri substrati organici facilmente fermentabili. E’ stata inoltre studiata la possibilità di impiego di reattori con biomassa adesa per migliorare la produzione specifica di metano e diminuire la lag phase. Dalla sperimentazione si può concludere che è possibile giungere allo sviluppo di metano dalla purea codigerendola assieme a refluo zootecnico. Per ottenere però produzioni significative la quantità di solidi volatili apportati dal rifiuto non deve superare il 50% dei solidi volatili complessivi. Viceversa, l’addizione di solfuri alla sola purea si è dimostrata ininfluente nel tentativo di sottrarre gli agenti inibitori della metanogenesi. Inoltre, l’impiego di supporti di riempimento lavorando attraverso processi batch sequenziali permette di eliminare, nei cicli successivi al primo, la lag phase dei batteri metanogeni ed incrementare la produzione specifica di metano.

Dark humour as a culture specific phenomenon: a study in screen translation

The present study aims at analyzing how dark humour as a cinematic genre travels cross-culturally through a specific mode of audiovisual translation, i.e. dubbing. In particular, it takes into consideration the processes involved in dubbing humour from English into Italian as observed in the English- and Italian-language versions of ten British and American dark comedies from the 1940s to the 2000s. In an attempt to identify some of the main mechanisms of the dark humour genre, the humorous content of the films was analyzed in terms of the elements on which specific scenes are based, mainly the non-verbal and verbal components. In the cases in which verbal elements were involved, i.e. the examples of verbally expressed humour, the analysis was concerned with whether they were adapted into Italian and to what effect. Quantification of the different kinds of dark humour revealed that in the sample of dark comedies verbal dark humour had a higher frequency (85.3%) than non-verbal dark humour (14.7%), which partially disconfirmed the first part of the research hypothesis. However, the significance of contextual elements in the conveying of dark humour, both in the form of Nsp VEH (54.31%) and V-V (V+VE) (21.68%), provided support for the hypothesis that, even when expressed verbally, dark humour is more closely linked to context-based rather than purely linguistic humour (4.9%). The second part of the analysis was concerned with an investigation of the strategies adopted for the translation of verbal dark humour elements from the SL (English) into the TL (Italian) through the filter of dubbing. Four translational strategies were identified as far as the rendering of verbal dark humour is concerned: i) complete omission; ii) weakening; iii) close rendering; and iv) increased effect. Complete omission was found to be the most common among these strategies, with 80.9% of dark humour examples being transposed in a way that kept the ST’s function substantially intact. Weakening of darkly humorous lines was applied in 12% of cases, whereas increased effect accounted for 4.6% and complete omission for 2.5%. The fact that for most examples of Nsp VEH (84.9%) and V-AC (V+VE) (91.4%) a close rendering effect was observed and that 12 out of 21 examples of V-AC (PL) (a combined 57%) were either omitted or weakened seemed to confirm, on the one hand, the complexity of the translation process required by cases of V-AC (PL) and V-AC (CS). On the other hand, as suggested in the second part of the research hypothesis, the data might be interpreted as indicating that lesser effort on the translator/adaptor’s part is involved in the adaptation of V-AC (Nsp VEH) and V-V (V+VE). The issue of the possible censorial intervention undergone by examples of verbal dark humour in the sample still remains unclear.

La traduzione intralinguistica, interlinguistica e intercodica della trilogia marsigliese di Jean Claude Izzo

Il testo ripercorre le origini del romanzo poliziesco, la sua struttura, le tecniche narrative utilizzate e l’evoluzione del genere che ha condotto alla nascita del Noir francese e del Noir Mediterraneo. Arrivando ad osservare che per le sue caratteristiche, la letteratura noir in generale presenta specificità di tipo culturale, ambientale e linguistico, che risultano molto evidenti nell’opera di Izzo, si giunge a considerare come sia necessario per il traduttore porsi rispetto all’opera come un antropologo o un etnologo, di farsi cioè interprete di una “cultura”. Nella terza parte del lavoro vengono presentati la Trilogia di Izzo, la struttura narrativa e gli elementi socio-culturali presenti nell’opera. La quarta parte propone le teorie relative sia al problema della traduzione interlinguistica, sia a quello della traduzione intralinguistica e successivamente dopo una analisi della traduzione italiana dei testi, presenta, in appendice, una possibile traduzione del prologo di Total Khéops, inteso come sintesi delle caratteristiche narrative e culturali dell’autore. La parte conclusiva di questo lavoro riguarda la traduzione intercodica e, seguendo la linea di pensiero che ha governato l’analisi della Trilogia vengono presi in esame e messi a confronto col testo narrativo alcuni dialoghi significativi dell’adattamento per la televisione.

Estro linguistico e problemi traduttivi in Mr Alfred M. A. di George Friel

My work is focused on George Friel, a distinguished Scottish writer known for his witty style bristling with puns and more or less literary allusions. In particular I proposed an annotated translation of what can be considered his masterpiece “Mr Alfred M.A.” in which wordplay has a central role for its plot. In the first part of my thesis I outlined the fundamental features of Friel’s writing: the wide variety of registers and styles, the rhythm and irony. Additionally I pointed out the strategies that the translator has to face when translating this text. Finally I identified the number of problems which may arise while translating Friel’s “Mr Alfred M.A.” into Italian with particular concern on the strategies of supplementation and explicitation for wordplay.

L'attrazione sessuale: processi psichici e strumenti di indagine. L'adattamento italiano del Cuestionario de Atraccion sexual

The sexual attraction is a complex emotional event, with somatic modifications, that like all the emotions, belongs to the psychic dimension and that, too much simply, can be led back, from a explicative point of view, to biological and psychical causes. The sexual attraction represents a personal experience, that is difficult to record, but of which every adult is able to delineate a correspondence with own “lived”. In the within of biological sciences, many experimental studies were been conducted with the aim to know which chemistries substances and cerebral zones are involved in front of a stimulus assessed like sexually attractive. Contrarily, there are little researches conducted in psychological field, aimed to the understanding the psychical factors, often unconscious, tinged to the subjective processes of sexual attraction: the sexual attraction remains an unexplored psychological event and unprovided of adapted instruments of assessment. The present thesis is oriented in primis to examine the existing scientific literature, in order to provide an exhaustive picture of the sexual attraction and to analyze the instruments of survey available for the empirical assessment of it. Secondly, the thesis is oriented to introduce two studies: the first study is aimed to adapt the Cuestionario de Atracción Sexual - CAS (Fernández ET to, 2006a; 2006b; 2006c) to the Italian language; the second study is aimed to assess the attitudes towards the sexual attraction in a sample of university students, in order to establish if some differences or association with some psychological dimensions (attachment stiles and alexithymia) exist.

Gli assetti proprietari e di controllo nell'agroalimentare italiano

The recent default of important Italian agri-business companies provides a challenging issue to be investigated through an appropriate scientific approach. The events involving CIRIO, FERRUZZI or PARMALAT rise an important research question: what are the determinants of performance for Italian companies in the Italian agri – food sector? My aim is not to investigate all the factors that are relevant in explaining performance. Performance depends on a wide set of political, social, economic variables that are strongly interconnected and that are often very difficult to express by formal or mathematical tools. Rather, in my thesis I mainly focus on those aspects that are strictly related to the governance and ownership structure of agri – food companies representing a strand of research that has been quite neglected by previous scholars. The conceptual framework from which I move to justify the existence of a relationship between the ownership structure of a company, governance and performance is the model set up by Airoldi and Zattoni (2005). In particular the authors investigate the existence of complex relationships arising within the company and between the company and the environment that can bring different strategies and performances. They do not try to find the “best” ownership structure, rather they outline what variables are connected and how they could vary endogenously within the whole economic system. In spite of the fact that the Airoldi and Zattoni’s model highlights the existence of a relationship between ownership and structure that is crucial for the set up of the thesis the authors fail to apply quantitative analyses in order to verify the magnitude, sign and the causal direction of the impact. In order to fill this gap we start from the literature trying to investigate the determinants of performance. Even in this strand of research studies analysing the relationship between different forms of ownership and performance are still lacking. In this thesis, after a brief description of the Italian agri – food sector and after an introduction including a short explanation of the definitions of performance and ownership structure, I implement a model in which the performance level (interpreted here as Return on Investments and Return on Sales) is related to variables that have been previously identified by the literature as important such as the financial variables (cash and leverage indices), the firm location (North Italy, Centre Italy, South Italy), the power concentration (lower than 25%, between 25% and 50% and between 50% and 100% of ownership control) and the specific agri – food sector (agriculture, food and beverage). Moreover we add a categorical variable representing different forms of ownership structure (public limited company, limited liability company, cooperative) that is the core of our study. All those variables are fully analysed by a preliminary descriptive analysis. As in many previous contributions we apply a panel least squares analysis for 199 Italian firms in the period 1998 – 2007 with data taken from the Bureau Van Dijck Dataset. We apply two different models in which the dependant variables are respectively the Return on Investments (ROI) and the Return on Sales (ROS) indicators. Not surprisingly we find that companies located in the North Italy representing the richest area in Italy perform better than the ones located in the Centre and South of Italy. In contrast with the Modigliani - Miller theorem financial variables could be significant and the specific sector within the agri – food market could play a relevant role. As the power concentration, we find that a strong property control (higher than 50%) or a fragmented concentration (lower than 25%) perform better. This result apparently could suggest that “hybrid” forms of concentrations could create bad functioning in the decision process. As our key variables representing the ownership structure we find that public limited companies and limited liability companies perform better than cooperatives. This is easily explainable by the fact that law establishes that cooperatives are less profit – oriented. Beyond cooperatives public limited companies perform better than limited liability companies and show a more stable path over time. Results are quite consistent when we consider both ROI and ROS as dependant variables. These results should not lead us to claim that public limited company is the “best” among all possible governance structures. First, every governance solution should be considered according to specific situations. Second more robustness analyses are needed to confirm our results. At this stage we deem these findings, the model set up and our approach represent original contributions that could stimulate fruitful future studies aimed at investigating the intriguing issue concerning the effect of ownership structure on the performance levels.
