Ronald Reagan Rain

RONALD REAGAN RAIN is a collection of poems that explore the wildness and terror lurking beneath the surface of contemporary suburban landscapes in a largely imagined America. Images of menacing policemen, bears, fast food restaurants, and dead film stars appear as substantive figures that embody loss and a preoccupation with aging, money woes, and a failed national confidence. Influenced by Russel Edson and Georg Trakl, poets whose work is characterized by Hermeticism and Expressionism, the poems in RONALD REAGAN RAIN suggest a similar dual need for autonomy and compromise in both highly charged poetic fragments and longer prose passages that examine issues of civil and personal estrangement as the outside world calls for constant introspection and reassessments of identity.

The Relationship of Culturally Responsive Instruction and the Reading Comprehension and Attitude of Struggling Urban Adolescent Readers

Culturally responsive instruction refers to the identification of relevant cultural aspects of students’ lives and infusion of these into the curriculum. This instructional approach assumes that a culturally appropriate curriculum can potentially motivate, engage, and lead students to higher rates of achievement. This quasi-experimental study (N=44) investigated the relationship of culturally responsive instruction and the reading comprehension and attitude of struggling urban adolescent readers. The study incorporated the use of culturally responsive instruction using culturally relevant literature (CRL), the Bluford Series Novels, as authentic texts of instruction. Participants were seventh grade reading students at a Title I middle school in South Florida. After a baseline period, two different classes were taught for 8 weeks using different methods. One class formed the experimental group (n=22) and the other class formed the comparison group (n=22). The CRI curriculum for the experimental group embraced the socio-cultural perspective through the use of small discussion groups in which students read and constructed meaning with peers through interaction with the Bluford Series Novels; gave written responses to multiple strategies according to SCRAP – Summarize, Connect, Reflect, Ask Questions, Predict; responded to literal and inferential questions, while at the same time validating their responses through evidence from the text. The Read XL (basal reader) curriculum of the comparison group utilized a traditional form of instruction which incorporated the reading of passages followed by responses to comprehension questions, and teacher-led whole group discussion. The main sources of data were collected from the Gates-MacGinitie Reading Tests, the Florida Assessments for Instruction in Reading (FAIR), and the Rhody Secondary Reading Attitude Assessment. Statistical analyses were performed using Repeated Measures ANOVAs. Findings from the study revealed that the experimental participants’ reading attitudes and FAIR comprehension scores increased when compared to the comparison group. Overall, the results from the study revealed that culturally responsive instruction can potentially foster reading comprehension and a more positive attitude towards reading. However, a replication of this study in other settings with a larger, more randomized sample size and a greater ethnic variation is needed in order to make full generalizations.

Stratégies des entreprises chinoises dans le secteur extractif dans l’Arctique

Poussée par une croissance économique rapide ces trente dernières années, la demande chinoise en matières premières a considérablement augmenté au cours de cette période. Premier importateur mondial de nombreux minerais depuis le début du XXIe siècle, la Chine, qui n’est pas un État côtier de l’Arctique, semble attentive au potentiel économique de la région, et notamment en ce qui a trait à l’exploitation des gisements miniers. Avec l’ouverture relative des accès maritimes à travers les passages arctiques, les entreprises chinoises seraient en mesure d’effectuer des économies sur les coûts de transport et pourraient plus aisément accéder aux gisements miniers du Groenland et de l’Arctique canadien. La montée en puissance de l’économie chinoise, qui s’est concrétisée depuis le début du siècle, son affirmation politique sur la scène mondiale, et sa diplomatie des ressources perçue comme agressive a contribué à développer une perception négative de la Chine au sein des opinions publiques canadiennes, danoises, groenlandaises, et islandaises. Dans un contexte de débats et d’inquiétudes sur les questions de souveraineté dans l’Arctique, les presses canadiennes, groenlandaises et danoises ont contribué à construire, dans leurs opinions publiques respectives ces dernières années, une certaine sinophobie face aux investissements directs à l’étranger chinois, qui débutent réellement en 2005. Par exemple, un sondage mené en 2015 par l’Asia Pacific Foundation of Canada faisait ressortir que près de 76% de la population canadienne était hostile à l’acquisition d’entreprises canadiennes par des entreprises chinoises, tous secteurs confondus. Au Groenland, la perspective d’opérations minières dirigées par des entreprises chinoises a provoqué l’ire des médias danois et groenlandais. Alors que certains dénoncent une stratégie géopolitique chinoise plus large dans cette région du monde, d’autres mettent l’accent sur les implications de la venue de nombreux travailleurs chinois, de même que sur les questions d’une Chine cherchant à assurer un accès à long terme aux ressources de la région, prétextant que le Groenland serait une région d’investissement majeur pour les entreprises chinoises. La Chine, par l’entremise de ses entreprises, chercherait-elle à faire main basse sur les ressources minières de l’Arctique ? L’Arctique canadien, le Groenland et le Grand Nord québécois sont-ils des territoires d’investissements majeurs pour les entreprises chinoises ? Comment les facteurs qui déterminent les choix des entreprises chinoises se sont-ils traduits dans l’Arctique ? Dans le cadre de cette recherche, trente-six entreprises et organes du gouvernement ont été consultés. Les résultats de l’enquête soulignent que ces territoires ne sont pas des régions où les entreprises chinoises investissent d’importantes sommes, mais demeurent attractifs en raison de la stabilité politique et du climat compétitif des affaires qui y règnent, ainsi que pour la qualité des ressources physiques qu’on y retrouve. Cependant, les acteurs chinois soulignent d’importants défis tels que le déficit en matière d’infrastructures maritimes et de communication dans l’Arctique, le manque d’informations sur les opportunités d’affaires, c’est le cas des projets disponibles au Groenland notamment, et les acteurs chinois soulignent également leur manque d’expérience à l’international, de même que le coût et la disponibilité de la main-d’oeuvre comme des défis importants pour les entreprises chinoises. En somme, les investissements des entreprises chinoises dans des projets miniers dans l’Arctique canadien et au Groenland s’insèrent, certes, dans les stratégies globales des entreprises chinoises qui visent à diversifier et sécuriser leurs sources d’approvisionnements. En revanche, s’il apparaît que les territoires arctiques ne sont pas des régions d’investissements majeurs pour les entreprises chinoises dans le secteur extractif, les acteurs chinois sondés raisonnent, de manière générale, selon une logique de marché et recherchent donc, pour la plupart, à assurer la rentabilité de leur entreprise par la réalisation de gains. Outre les fluctuations des prix des matières premières sur les marchés mondiaux qui affectent grandement les opérations minières globales, de nombreux facteurs dans l’Arctique tels que l’éloignement, les conditions météorologiques extrêmes, et le manque d’infrastructures augmentent considérablement le coût de faire des affaires dans le secteur minier dans l’Arctique, qui demeure un marché niche.

«Horions», roman (extraits) ; suivi de Les fonctions extra-narratives dans "Trou de mémoire" d’Hubert Aquin

Ce mémoire de recherche-création porte sur les fonctions extra-narratives telles que définies par Gérard Genette, soit les fonctions de régie, testimoniale, de communication et idéologique, dans le contexte d’un récit à narrateurs multiples. Deux approches ont été privilégiées ici : l’écriture d’un roman comportant plusieurs instances de narration, et l’analyse d’un roman offrant un type comparable de structure narrative, soit Trou de mémoire d’Hubert Aquin. Ainsi, la partie création comprend des extraits d’Horions, roman hybride combinant les formes romanesque, poétique et dramatique, et dont ne figurent dans ce mémoire que des extraits des passages romanesques. Une instance narrative d’abord anonyme, puis nommée à la toute fin, retrace son passé en prêtant une voix à des êtres qui l’habitent, notamment un homme violent et un fils aphasique. Ces personnages-narrateurs exercent, outre la fonction narrative, d’autres fonctions qui justifient en quelque sorte leur présence : l’un est témoin de l’intrigue qu’il rapporte, l’autre communique avec un narrataire intra-diégétique, un troisième rend compte des émotions du protagoniste… Quant à la partie réflexion, elle se fonde sur les notions de narrateur, de narrataire et de situation narrative, mais se concentre sur les fonctions extra-narratives exercées par les diverses instances prenant la parole au fil du récit. Ces notions permettent de rendre compte de la structure narrative d’ensemble du roman Trou de mémoire d’Hubert Aquin, lequel juxtapose plusieurs voix, soit celles de Pierre X. Magnant, Rachel Ruskin, Olympe Ghezzo-Quénum et Charles-Édouard Mullahy. Un bref retour sur l’écriture d’Horions et sur les enjeux du récit à plusieurs narrateurs se prévalant des diverses fonctions extra-narratives complète la démarche.

Towards in silico IBV vaccine design: defining the role of polymorphism in viral attenuation

The gammacoronavirus, Infectious Bronchitis Virus (IBV), is a respiratory pathogen of chickens. IBV is a constant threat to poultry production as established vaccines are often ineffective against emerging strains. This requires constant and rapid vaccine production by a process of viral attenuation by egg passage, but the essential forces leading to attenuation in the virus have not yet been characterised. Knowledge of these factors will lead to the development of more effective, rationally attenuated, live vaccines and reduction of the mortality and morbidity caused by this pathogen. M41 CK strain was egg passaged four times many years ago at Houghton Poultry Research Station and stored as M41-CK EP4 (stock virus at The Pirbright Institute since 1992). It was the first egg passage to have its genome pyrosequenced and was therefore used as the baseline reference. The overall aim of this project was to analyse deep sequence data obtained from four IBV isolates (called A, A1, C and D) each originating from the common M41-CK EP4 (ep4) and independently passaged multiple times in embryonated chicken eggs (figure 1.1). Highly polymorphic encoding regions of the IBV genome were then identified which are likely involved in the attenuation process through the formation of independent SNPs and/or SNP clusters. This was then used to direct targeted investigation of SNPs during the attenuation process of the four IBV passages. A previously generated deep sequence dataset was used as a preliminary map of attenuation for one virulent strain of IBV. This investigation showed the nucleocapsid and spike as two highly polymorphic encoding regions within the IBV genome with the highest proportion of SNPs compared to encoding region size. This analysis then led to more focussed studies of the nucleocapsid and spike encoding region with the ultimate aim of mapping key attenuating regions and nucleotide positions. The 454 pyrosequencing data and further investigation of nucleocapsid and spike encoding regions have identified the SNPs present at the same nucleotide positions within analysed A, A1, C and D isolates. These SNPs probably play a crucial role in viral attenuation and universal vaccine production but it is not clear if independent SNPs are also involved in loss of virulence. The majority of SNPs accumulated at different nucleotide positions without further continuation in Sanger sequenced egg passages presenting S2 subunit (spike) and nucleocapsid as polymorphic encoding regions which in nature remain highly conserved.

La storia di Iefte (Jdc 10,6-12,7). Studi sul testo biblico e sulla sua ricezione nell'Antichità

La tesi tratta la storia veterotestamentaria di Iefte (Jdg 10,6-12,7). Il lavoro è diviso in due parti: la prima concerne la formazione del testo biblico e propone una nuova analisi critico-testuale del passo attraverso il confronto tra TM, LXX, Vg e altre fonti. Questo raffronto esamina i rapporti tra il TM e il modello ebraico dei LXX e le differenze tra le diverse recensioni dei LXX; inoltre, lo studio del lessico e dei temi in esso presenti porta alla formulazione di una nuova ipotesi sul tempo della composizione e sulla contestualizzazione storica e letteraria dell'episodio all'interno del corpus biblico. La seconda parte si concentra sulla storia delle interpretazioni del passo nel mondo latino e greco dal I secolo d.C. all'inizio del V secolo, e ha portato alla costituzione di un dossier di brani, esaminati nel loro contesto, che commentano o citano l'episodio. L'attenzione al contesto ha permesso di risolvere alcuni problemi che finora hanno impedito la ricostruzione del percorso esegetico del brano (attribuzione di alcuni frammenti catenari, datazione del De virginitate di Ambrogio, ecc.) Questo nuovo approccio di ricerca combina un'analisi completa dell'episodio biblico con uno studio approfondito della sua esegesi. Rivela così, da un lato, le scelte effettuate durante la composizione di un testo scritturistico problematico, e, dall'altro, i diversi meccanismi utilizzati dagli esegeti per spiegare il significato di una storia in cui la bontà di Dio, che ha tollerato il sacrificio umano, è messa in discussione.

Self-supervised information retrieval: a novel approach based on Deep Metric Learning and Neural Language Models

Most of the existing open-source search engines, utilize keyword or tf-idf based techniques to find relevant documents and web pages relative to an input query. Although these methods, with the help of a page rank or knowledge graphs, proved to be effective in some cases, they often fail to retrieve relevant instances for more complicated queries that would require a semantic understanding to be exploited. In this Thesis, a self-supervised information retrieval system based on transformers is employed to build a semantic search engine over the library of Gruppo Maggioli company. Semantic search or search with meaning can refer to an understanding of the query, instead of simply finding words matches and, in general, it represents knowledge in a way suitable for retrieval. We chose to investigate a new self-supervised strategy to handle the training of unlabeled data based on the creation of pairs of ’artificial’ queries and the respective positive passages. We claim that by removing the reliance on labeled data, we may use the large volume of unlabeled material on the web without being limited to languages or domains where labeled data is abundant.

Plutarch's chemistry of stones and metals: conceptions and explanations. With an appendix on the TheSu XML annotation scheme

This dissertation presents a systematic and analytic overview of most of the information related to stones, minerals, and stone masonry which is found in the corpus of Plutarch of Chaeronea, combined with most of the information on metals and metalworking which is connected to the former. This survey is intended as a first step in the reconstruction of the full landscape of ‘chemical’ ideas occurring in Plutarch’s writings; accordingly, the exposition of the relevant passages, the assessment of their possible interpretations, the discussion on their implications, and their contextualization in the ancient traditions have been conducted with a special interest in the ‘mineralogical’ and ‘metallurgic’ themes developed in the frame of natural philosophy and meteorology. Although in this perspective physical etiology could have come to acquire central prominence, non-etiological information on Plutarch’s ideas on the nature and behaviour of stones and metals has been treated as equally relevant to reach a fuller understanding of how Plutarch conceptualized and visualized them in general, in- and outside the frame of philosophical explanation. Such extensive outline of Plutarch’s ideas on stones and metals is a prerequisite for an accurate inquiry into his use of the two in analogies, metaphors, and symbols: to predispose this kind of research was another aim of the present survey, and this aim has contributed to shape it; moreover, a special attention has been paid to the analysis of analogical and figurative speaking due to the nature itself of a large part of Plutarch’s references to stones and metals, which are either metaphorical, presented in close association with metaphors, or framed in analogies. Much of the information used for the present overview has been extracted —always with supporting argumentation— from the implications of such metaphors and analogies.

The conceptualisation of music in ancient Greek thought (V century B.C. – II century B.C.)

The focus of this dissertation is the analysis of the music-related philosophical passages from the 5th century B.C. to the 2nd century B.C. It aims to provide a multifaceted view towards music as a cultural phenomenon, which is based primarily on the philological and culturological explorations instead of the technical-musicological approach. The texts from our selected period attest that mousikē had an extremely broad conceptualisation which led to the attribution of the different, sometimes completely opposite value: from an insignificant performative practice to an activity which corresponds to the divine laws and directly affects the human soul. The discussed testimonia provide evidence of defining music both as an exclusively acoustic phenomenon and as a philosophically significant concept that oversteps the sonic definition. Our sources clearly demonstrate that mousikē was a polysemous term: it was understood as an interdisciplinary form of art (as the arts of the Muses), though it was also used to indicate the exclusively instrumental music or a philosophical concept, which does not necessarily define sound as its essential quality. The aim of this dissertation is to clarify the arguments behind each of these positions, to analyse whether such different modes of conceptualisation are compatible among themselves, and to see how they fit together into explaining what was understood as music in Antiquity. In this thesis we explore the conceptual framework of mousikē and analyse what enabled the musical thought to be worthy of the attention of the greatest philosophical minds. We will demonstrate that it was not the sound or the artistic practices that were central in the philosophical thought on music, but instead the embedded structural qualities that have correspondence to the universal proportions of the cosmic world and which are perceptible to the listeners through the medium of sound.

Analysis of urban infrastructure for sustainable mobility through instrumented bicycles for students

In Europe almost 80% of the continent's population lives in cities. It is estimated that by 2030 most regions in Europe which contain major cities will have even more inhabitants on 35–60% more than now. This process generates a consequent elevate human pressure on the natural environment, especially around large urban agglomerations. Cities could be seen as an ecosystem, represented by the dominance of humans that re-distribute organisms and fluxes and represent the result of co-evolving human and natural systems, emerging from the interactions between humans, natural and infrastructures. Roads have a relevant role in building links between urban components, creating the basis on which it is founded the urban ecosystem itself. This thesis is focused on the research for a comprehensive model, framed in European urban health & wellbeing programme, aimed to evaluate the determinants of health in urban populations. Through bicycles, GPS and sensor kits, specially developed and produced by University of Bologna for this purpose, it has been possible to conduct on Bologna different direct observations that oriented the novelty of the research: the categorization of university students cyclists, connection among environmental data awareness and level of cycling, and an early identification of urban attributes able to impact on road air quality and level of cycling. The categorization of university students’ cyclist has been defined through GPS analysis and focused survey, that both permit to identify behavioural and technical variables and attitudes towards urban cycling. The statistic relationship between level of cycling, seen as number of bicycles passages per lane and pollutants level, has been investigated through an inverse regression model, defined and tested through SPSS software on the basis of the data harvest. The research project that represents a sort of dynamic mobility laboratory on two wheels, that permits to harvest and study detected parameters.

NB-IoT via non terrestrial networks

Massive Internet of Things is expected to play a crucial role in Beyond 5G (B5G) wireless communication systems, offering seamless connectivity among heterogeneous devices without human intervention. However, the exponential proliferation of smart devices and IoT networks, relying solely on terrestrial networks, may not fully meet the demanding IoT requirements in terms of bandwidth and connectivity, especially in areas where terrestrial infrastructures are not economically viable. To unleash the full potential of 5G and B5G networks and enable seamless connectivity everywhere, the 3GPP envisions the integration of Non-Terrestrial Networks (NTNs) into the terrestrial ones starting from Release 17. However, this integration process requires modifications to the 5G standard to ensure reliable communications despite typical satellite channel impairments. In this framework, this thesis aims at proposing techniques at the Physical and Medium Access Control layers that require minimal adaptations in the current NB-IoT standard via NTN. Thus, firstly the satellite impairments are evaluated and, then, a detailed link budget analysis is provided. Following, analyses at the link and the system levels are conducted. In the former case, a novel algorithm leveraging time-frequency analysis is proposed to detect orthogonal preambles and estimate the signals’ arrival time. Besides, the effects of collisions on the detection probability and Bit Error Rate are investigated and Non-Orthogonal Multiple Access approaches are proposed in the random access and data phases. The system analysis evaluates the performance of random access in case of congestion. Various access parameters are tested in different satellite scenarios, and the performance is measured in terms of access probability and time required to complete the procedure. Finally, a heuristic algorithm is proposed to jointly design the access and data phases, determining the number of satellite passages, the Random Access Periodicity, and the number of uplink repetitions that maximize the system's spectral efficiency.

Le radici del monoteismo israelitico come riflesso dell'idea di regalita divina in epoca pre-esilica

Questa tesi è un contributo al dibattito meta-terminologico sull'uso scientifico del termine "monoteismo" in relazione alla religione dell'Israele antico. L'attenzione è rivolta principalmente a un tema specifico: l'esplorazione della nozione teistica di "esistenza" divina (implicita nell'uso di "monoteismo" come lente di osservazione) e il problema della sua applicazione alle concettualizzazioni della divinità che emergono nella Bibbia ebraica. In primo luogo, il "monoteismo" come termine e concetto viene ricondotto alle sue origini storiche nell'ambiente intellettuale del platonismo di Cambridge nell'Inghilterra del XVII secolo. Poi, si affronta il dibattito contemporaneo sull'uso del termine "monoteismo" in relazione alla religione dell'Israele antico e si evidenzia il ruolo dell'"esistenza" teistica come lente distorcente nella lettura dei testi biblici. La maggior parte della tesi sostiene questo assunto con una lettura esegetica dettagliata di tre passi biblici scelti come casi di studio: Sal 82; 1Re 18,20-40* e Zc 14,9. Queste analisi mostrano come la nozione teistica di un'esistenza divina astratta non sia in grado di spiegare la rappresentazione del divino che emerge da questi testi. Allo stesso tempo, il potere divino come categoria euristica viene proposto come un'alternativa più adatta a spiegare queste concettualizzazioni della divinità. L'ultima sezione elabora ulteriormente questi risultati. Qui la regalità di YHWH, come immagine metaforica del suo potere, viene utilizzata per descrivere i cambiamenti nella concettualizzazione di questa divinità. L'argomentazione finale è che in nessuna parte del materiale biblico affrontato in questa tesi si trova una nozione simile a quella di esistenza divina astratta. Poiché tale nozione è implicita nell'uso del termine "monoteismo", questi risultati richiedono una considerazione ancora più attenta del suo uso nel dibattito scientifico.
