    La tesi esplora i potenziali benefici e rischi dell’implementazione della tecnologia blockchain in vari settori del trasporto, tra cui la catena di approvvigionamento, la logistica, le autostrade, il trasporto marittimo, le città intelligenti e i sistemi di trasporto urbano pubblico. Questi settori stanno sempre più prendendo in considerazione la tecnologia blockchain per le sue caratteristiche di rete distribuita e decentralizzata, di crittografia avanzata, immutabilità dei dati e consenso decentralizzato. Una particolare attenzione è rivolta all'esaminare il potenziale della blockchain nei sistemi di riscossione dei pedaggi elettronici per le autostrade. Inoltre, lo studio mira a valutare l'impatto dell'espansione della rete autostradale e dell’introduzione di sistemi di pagamento basati su blockchain sulla crescita economica europea. In generale, la ricerca contribuisce a colmare il divario tra la conoscenza teorica della tecnologia blockchain e la sua implementazione pratica nel settore dei trasporti. I contributi di questa tesi sono presentati in tre capitoli distinti. Il Capitolo 2 rivede la letteratura sulla diffusione, i benefici e i rischi della tecnologia blockchain nel settore dei trasporti e sui potenziali ostacoli alla sua adozione diffusa. Il Capitolo 3 propone ed implementa un modello teorico della tecnologia blockchain di Bitcoin per i pagamenti integrati tra aziende che gestiscono diverse sezioni della stessa rete autostradale. Il Capitolo 4 sviluppa un modello macroeconomico che studia gli effetti delle autostrade e dell'infrastruttura dei pagamenti fornita dalla blockchain di Bitcoin sulla crescita economica utilizzando dati panel.The thesis explores the potential of implementing blockchain technology across various transportation sectors, including supply chain, logistics, motorways, shipping, smart cities, and public urban transport systems. These sectors are increasingly considering blockchain to leverage its features such as distributed networks, advanced cryptography, data immutability, and decentralized consensus. Special attention is given to examining blockchain's potential in electronic toll collection systems for highways. Additionally, the study aims to assess the impact of expanding the highway network and introducing blockchain-based payment systems on European economic growth. Overall, the research contributes to bridging the gap between theoretical knowledge of blockchain technology and its practical implementation in transportation. The contributions of this thesis are presented across three distinct chapters. Chapter 2 reviews the literature on the diffusion of blockchain technology in the transportation sector and potential barriers to its widespread adoption. Chapter 3 proposes and implements a theoretical model of Bitcoin blockchain technology for integrated payments among companies managing different sections of the same highway lane. Chapter 4 develops a macroeconomic model that studies the effects of highways and Bitcoin blockchain infrastructure on economic growth through panel data

    Background: Osmophobia, is common among primary headaches, with prevalence of migraine. The study aimed to evaluate prevalence and clinical characteristics of patients with osmophobia in a cohort of primary headache patients selected at a tertiary headache center. The second aim was to verify the possible predicting role of osmophobia in preventive treatment response in a sub cohort of migraine patients. Methods: This was an observational retrospective cohort study based on data collected in a tertiary headache center. We selected patients aged 18–65 years, diagnosed as migraine without aura (MO), migraine with aura (MA) or Chronic Migraine (CM), Tension-Type Headache (TTH); and Cluster Headache (CH). We also selected a sub-cohort of migraine patients who were prescribed preventive treatment, according to Italian Guidelines, visited after 3 months follow up. Patients were considered osmophobic, if reported this symptom in at least the 20% of headache episodes. Other considered variables were: headache frequeny, the migraine disability assessment (MIDAS), Allodynia Symptom Checklist, Self-rating Depression scale, Self-rating Anxiety scale, Pain intensity evaluated by Numerical Rating Scale-NRS- form 0 to 10. Results: The 37,9% of patients reported osmophobia (444 patients with osmophobia, 726 without osmophobia). Osmophobia prevailed in patients with the different migraine subtypes, and was absent in patients with episodic tension type headache and cluster headache (chi square 68.7 DF 7 p < 0.0001). Headache patients with osmophobia, presented with longer hedache duration (F 4.91 p 0.027; more severe anxiety (F 7.56 0.007), depression (F 5.3 p 0.019), allodynia (F 6 p 0.014), headache intensity (F 8.67 p 0.003). Tension type headache patients with osmophobia (n° 21), presented with more frequent headache and anxiety. A total of 711 migraine patients was visited after 3 months treatment. The change of main migraine features was similar between patients with and without osmophobia. Conclusions: While the present study confirmed prevalence of osmophobia in migraine patients, it also indicated its presence among chronic tension type headache cases, marking those with chronic headache and anxiety. Osmophobia was associated to symptoms of central sensitization, as allodynia. It was not relevant to predict migraine evolution after first line preventive approach

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.

    Author in Essay by I. A. Goncharov “Pepiniere”

    No full text
    Features of the embodiment of the author’s position in the essay by I. A. Goncharov “Pepiniere” are considered. The relevance of the study is due to the poorly studied poetics of this work. A review of the scientific literature on relevant topics is performed. Methodological and theoretical definitions are given. The scientific novelty of the article is in the fact that for the first time attention is paid to artistic techniques that allow to identify the author's position in the specified literary text. The author of the article grounds her opinion from the fact that, despite the dominance of the subjective point of view, other characters’ views stand out in the work. It is concluded in the study that the text of the work represents a biographical author and author-creator. It was established that the position of the author-creator is expressed through the title, epigraphs, which are quotes, as well as through different points of view, including the author-character, the author-narrator, the characters of the work. The author of the article dwells in detail on different ways of expressing the points of view of the author-character and the author-narrator. It is proved that the point of view of the author-character and the author-narrator can intersect, they are interchanged. The author's development of the term comic “point of view” is presented in the article

    Espai i identitat en l'obra de Jordi Pere Cerdà. Una geografia literària cerdaniana

    No full text
    L'obra de l'autor nord-català Jordi Pere Cerdà (1920-2011) teixeix una cartografia literària que abasta tota dimensió espacial -real, imaginada i ficcional. Les prospeccions que assagen els seus texts es fonen en el medi natural i rural, canten a l'amor, als veïns i als éssers fantàstics del folklore català, es comprometen amb els refugiats encarant-se a tota frontera i, també, a tot abisme interior i exterior que oprimesca l'ésser. El mapatge cognitiu i literari que crea Cerdà sobrepassa qualsevol obstacle per construir espais oberts i possibles, en comunió amb l'altre. Partint d'una aproximació teòrica geocrítica, aquest treball d'investigació aprofundeix en diverses nocions sobre l'espacialitat lligades a un context convuls, ple de transformacions a nivell socioeconòmic, polític, cultural i lingüístic, el qual determinarà la vida d'un autor i d'un territori transfronterer com el de la Cerdanya i la Catalunya del Nord. En definitiva, la rica experiència vital de Jordi Pere Cerdà ens permet reflexionar sobre les relacions que vulguem establir entre els individus i amb el nostre hàbitat natural i cultural, a fi d'esdevenir membres actius que participen de la transformació dels espais que configuren les nostres identitats.The work of the North Catalan author Jordi Pere Cerdà (1920-2011) weaves a literary cartography which reaches all spatial dimensions -real, imagined and fictional. The prospections proved by their texts merge with the natural and rural environment, sing to love, neighbours and the fantastic beings of the Catalan folklore. Such prospections also commit themselves with the refugees facing every frontier and, also, facing all interior and exterior abyss that oppresses the being. The cognitive and literary mapping created by Cerdà overcomes any obstacle to construct opened and possible spaces, in communion with the other. Based on the theoretical approach called geocriticism, this research study delves into various notions about spatiality linked to a convulsive context, full of transformations at a socioeconomic, political, cultural and linguistic level; these transformations will determine the life of an author and a cross-border territory such as Cerdagne and Northern Catalonia. In short, the rich experience of Jordi Pere Cerdà allows us to reflect on the relationships we want to establish between individuals, as well as between human groups and our natural and cultural habitat, in order to become active members that participate in the transformation of the spaces that make up our identities.Programa de Doctorat en Llengües Aplicades, Literatura i Traducci

    Treball Final de Grau en Mestre o Mestra d'Educació Primària (Pla de 2018). Codi: MP1840. Curs acadèmic: 2021/2022El treball de fi de grau que aneu a veure a continuació, és un projecte que consisteix en com es poden treballar a les aules de primària els llibres de l’autora i il·lustradora Olga de Dios. Tractant de treballar el llibre com a objecte artístic a nivell elemental. A més, de presentar a l’autora i il·lustradora, donarla a conèixer i veure els valors que transmet, també llegiríem quatre de les seues obres a l’aula com són: “Leotolda”, “En familia”, “Rana de Tres Ojos”, i “Pájaro Amarillo”. Tot açò sumat a la realització d’un quadern de classe on es colorejaria alguns dels seus personatges de les obres seguint pautes a nivell curricular. Realitzaríem també una eixida a la biblioteca municipal, on a banda de rebre una educació no formal, ens facilitaria una mica el fet d’endinsar-nos al món de la il·lustració infantil, on allí dins, el professional encarregat ens guiarà pels llibres que hi haurà a la biblioteca. I, per a concloure, elaboraríem un llibre creat per l’alumnat on seguint unes pautes establertes per Olga de Dios al seu llibre “Leotolda” buscaríem fer una retroalimentació intentant contactar amb ella. D’aquesta manera tancaríem el cicle que vam començar donant-la a conèixer com a escriptora i il·lustradora, i exploraríem on està el límit de la creativitat del propi alumnat.The final degree project you are going to see below is a project that looks at how books by author and illustrator Olga de Dios can be worked on in primary school classrooms. Considering the book as an artistic object at an elementary level. Besides presenting the author and illustrator, introducing her, and seeing the values she transmits, we would also read four of her works in the classroom, such as: "Leotolda”, "In the family", "Three-Eyed Frog", and "Yellow Bird.". All this, in addition to the creation of a class notebook in which some of his characters from her work would be colored following guidelines at the curricular level. We would also go out to the local library, where in addition to receiving a non-formal education, it would make it a little easier for us to enter the world of children's illustration, where inside, the professional in charge will guide us through the books which will be in the library. And, to conclude, we would make a book created by the students, where following some guidelines established by Olga de Dios in her book "Leotolda" we would look for feedback by trying to contact her. In this way, we would close the cycle that we started by presenting her as an author and illustrator, and we would explore where the limit of creativity of the students themselves is

    The construction of Karen Karnak: The multi-author-function

    No full text
    This thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
