Mapping the Liminal Experience of Eastern Europe in Selected American Works, 1965-2002

The purpose of this dissertation is to study literary representations of Eastern Europe in the works of celebrated and less-known American authors, who visited and narrated the region between the mid-1960s and early 2000s. The main critical body focuses on Eastern Europe before 1989 and encompasses three major voices of American literature: John Updike, Joyce Carol Oates, and Philip Roth. However, in the last chapter I also explore American literary perceptions of the area following the collapse of communism. Importantly, the term “Eastern Europe” as used in this dissertation is charged with significance. I approach it not only as a space on the map or the geopolitical construct which emerged in the aftermath of the Second World War, but rather as a conceptual category and a repository of meanings built out of fact and fantasy: specific historical, political and cultural realities interlaced with subjective worldviews, preconceptions, and mental images. The critical framework of this dissertation is twofold. I reach for the concept of liminality to elucidate the indeterminacy and malleability which lies at the heart of the object of study—the idea, image, and experience of Eastern Europe. Bearing in mind the nature of the works under analysis, all of which were inspired by actual visits behind the Iron Curtain, I propose to interpret these transatlantic literary journeys in terms of generative experience, where Eastern Europe is mapped as a liminal space of possibility; a contact zone between cultures and, potentially, the locus of self-discovery and individual transformation. If liminality is the metaphor or a lens that I employ in order to account for the nature of the analyzed works and the complex terrain they map, imagology, whose purpose is to study the processes of constructing selfhood and otherness in literature, provides me with the method and the critical vocabulary for analyzing selected literary representations. The dissertation is divided into six chapters, the last of which serves as coda to the previous discussion. The first two chapters constitute the critical foundation of this work. Then, in chapters 3, 4, and 5 I study American images of Eastern Europe in the works written by John Updike, Joyce Carol Oates, and Philip Roth, respectively. The last, sixth chapter of this dissertation is divided into two parts. In the first one, I discuss new critical perspectives and avenues of research in the study of Eastern Europe following the collapse of communism. Then, I carry out a joint analysis of four works written after 1989 by Eva Hoffman, Arthur Phillips, John Beckman, and Gary Shteyngart. The dissertation ends with conclusions in which I summarize my findings and reflections, and suggest implications for future research. As this dissertation seeks to demonstrate, Eastern Europe portrayed in the analyzed works oscillates between contradictory representations which are contingent upon a number of factors, most importantly who maps it and in what context. Even though each experience of Eastern Europe is distinct and fueled by the profiles, identities, and interests of the characters and their creators, I have found out that certain patterns of othering are present in all the works. Thus, my research seems to suggest that there is something of a recurrent literary image of Eastern Europe, which goes beyond the context of the Cold War. Accordingly, while this dissertation hopes to be a valid contribution to the study of literary and cultural mappings of Eastern Europe, it also generates new questions regarding the current, post-communist representation of the area and its relationship to the national tropes explored in my work.

Les grandes surfaces suivi de La logique du seuil ou la problématique de l’altérité dans Autoportraits de Marie Uguay et Nombreux seront nos ennemis de Geneviève Desrosiers

Les recueils de poésie Autoportraits de Marie Uguay et Nombreux seront nos ennemis de Geneviève Desrosiers appartiennent tous deux au genre de l’intimisme. Celui-ci est principalement caractérisé par une observation rapprochée du quotidien. Mon projet est constitué de deux volets : une recherche sur l’intimisme chez Uguay et Desrosiers, ainsi qu’un projet de création inspiré de leur poésie. Dans le volet recherche de mon mémoire, je me penche sur la logique du seuil et les rapports problématiques à l’altérité dans ces deux recueils. Dans Autoportraits et Nombreux seront nos ennemis, la position en retrait ou sur le seuil du « Je » permet d’observer ce qui l’entoure en conservant une perspective intime confortable où il ne se retrouve pas confronté à l’altérité. Les poèmes de la partie création de mon mémoire témoignent de l’inventivité dont le « Je » fait preuve afin d’échapper à son quotidien et sont empreints d’une perméabilité entre rêve et réalité. Le quotidien statique se présente comme un piège, un enfermement. La tension entre l’ici et l’ailleurs est exprimée dans les textes par une logique de l’attente; celle d’un nouveau départ et de la réalisation du rêve. Par cette pratique, je souhaite jouer avec les dangers de l’intimisme : ceux d’un narcissisme ou d’un sentimentalisme exacerbés.

SECURITY, PRIVACY AND APPLICATIONS IN VEHICULAR AD HOC NETWORKS

With wireless vehicular communications, Vehicular Ad Hoc Networks (VANETs) enable numerous applications to enhance traffic safety, traffic efficiency, and driving experience. However, VANETs also impose severe security and privacy challenges which need to be thoroughly investigated. In this dissertation, we enhance the security, privacy, and applications of VANETs, by 1) designing application-driven security and privacy solutions for VANETs, and 2) designing appealing VANET applications with proper security and privacy assurance. First, the security and privacy challenges of VANETs with most application significance are identified and thoroughly investigated. With both theoretical novelty and realistic considerations, these security and privacy schemes are especially appealing to VANETs. Specifically, multi-hop communications in VANETs suffer from packet dropping, packet tampering, and communication failures which have not been satisfyingly tackled in literature. Thus, a lightweight reliable and faithful data packet relaying framework (LEAPER) is proposed to ensure reliable and trustworthy multi-hop communications by enhancing the cooperation of neighboring nodes. Message verification, including both content and signature verification, generally is computation-extensive and incurs severe scalability issues to each node. The resource-aware message verification (RAMV) scheme is proposed to ensure resource-aware, secure, and application-friendly message verification in VANETs. On the other hand, to make VANETs acceptable to the privacy-sensitive users, the identity and location privacy of each node should be properly protected. To this end, a joint privacy and reputation assurance (JPRA) scheme is proposed to synergistically support privacy protection and reputation management by reconciling their inherent conflicting requirements. Besides, the privacy implications of short-time certificates are thoroughly investigated in a short-time certificates-based privacy protection (STCP2) scheme, to make privacy protection in VANETs feasible with short-time certificates. Secondly, three novel solutions, namely VANET-based ambient ad dissemination (VAAD), general-purpose automatic survey (GPAS), and VehicleView, are proposed to support the appealing value-added applications based on VANETs. These solutions all follow practical application models, and an incentive-centered architecture is proposed for each solution to balance the conflicting requirements of the involved entities. Besides, the critical security and privacy challenges of these applications are investigated and addressed with novel solutions. Thus, with proper security and privacy assurance, these solutions show great application significance and economic potentials to VANETs. Thus, by enhancing the security, privacy, and applications of VANETs, this dissertation fills the gap between the existing theoretic research and the realistic implementation of VANETs, facilitating the realistic deployment of VANETs.

‘You, my body, and my mind, one of these will go’: Madness as Disguise in Samuel Beckett's Murphy and Endgame

ithin the wide topic of disguise in literature, we could signal a subcurrent which can be found in a number of literary texts: the idea of madness as a disguise, i.e. the creation or invention of a ‘false self’ as a mask which is presented to the world and which conceals the real self. In The Divided Self (1960), R. D. Laing deals with the “personality, false self, mask, front or persona that (...) [schizophrenic] wear” (73). Using as a basis Laing’s theories on schizophrenia and the creation of a false-self system, we will analyze two works by Samuel Beckett: Murphy and Endgame, where we find the uses of madness as disguise in a series of ways: through the usage of ‘disguised’ language (what we could refer to as schizophrenese) which acts as a mask for real meaning; through odd ‘schizophrenic’ behaviour on the part of the characters (which screens real intentions), and, mainly, through the creation of a ‘false self’ which acts as a disguise and barrier between the inner self and the real world. These two works by Samuel Beckett, where real intentions and meanings are continuously concealed and disguised in a desperate attempt to preserve the inner self, lend themselves to an analysis of madness as disguise, precisely the one we attempt to carry out in our paper.

Entrepreneurship in project management systems: proposal of a model and preliminary empirical evidence

This study analyzes the manifestation of the dimensions of Entrepreneurial Orientation (EO) and Project Management Systems (PMS). We used a qualitative approach to conduct exploratory research through a study in literature and a pilot case in a software company. Data was collected from semi structured interviews, documents, and records on file, then triangulated and treated with content analysis. The model proposed for the relationship between the types of PMS (ad hoc, Classic PM, innovation, entrepreneurship/intrapreneurship) and the dimensions of EO (innovativeness, risk-taking, proactiveness, competitive aggressiveness, and autonomy), was partially corroborated by empirical studies. New studies are suggested to validate the applicability and setup of the model.

The impact of culture and corporate governance in dividend policy: evidence from emerging and developed countries

The present research aims to analyse the impact of corporate governance and cultural dimensions in dividend policy. The corporate governance and dividend policy have a close relationship, in that both are evidenced in literature to mitigate agency problems. Cultural factors are also related to agency problems. The existence of agency problems and their solutions differs across countries and it is related to the implementation of the mechanisms of governance. So, cultural factors may have influence on corporate governance and dividend policy. Our sample consists in 1 232 companies belonging to the main indices of 38 countries classified as emerging or developed. To measure the quality of firm level corporate governance, we use the ASSET4 Corporate Governance Performance Index, developed by Thomson Reuters, and as proxy of culture we use three cultural dimensions developed by Geert Hofstede, namely uncertainty avoidance, masculinity and indulgence. We obtained significant empirical evidence that firms with high quality of corporate governance pay higher dividends. With regard to cultural factors, we confirm that in countries with high levels of masculinity and uncertainty avoidance, the dividend payout ratio is lower. On the other hand, countries with high level of indulgence have higher dividend payout ratio. However, we verify that the impact of cultural effects is minimized when the firms have a high quality level of corporate governance. Additionally, we found that the impact of corporate governance and cultural factors in dividend policy differs when dealing with emerging or developed countries.

Diversity and Stability in Food Webs : Impacts of Non-Equilibrium Dynamics, Topology and Variation

With progressive climate change, the preservation of biodiversity is becoming increasingly important. Only if the gene pool is large enough and requirements of species are diverse, there will be species that can adapt to the changing circumstances. To maintain biodiversity, we must understand the consequences of the various strategies. Mathematical models of population dynamics could provide prognoses. However, a model that would reproduce and explain the mechanisms behind the diversity of species that we observe experimentally and in nature is still needed. A combination of theoretical models with detailed experiments is needed to test biological processes in models and compare predictions with outcomes in reality. In this thesis, several food webs are modeled and analyzed. Among others, models are formulated of laboratory experiments performed in the Zoological Institute of the University of Cologne. Numerical data of the simulations is in good agreement with the real experimental results. Via numerical simulations it can be demonstrated that few assumptions are necessary to reproduce in a model the sustained oscillations of the population size that experiments show. However, analysis indicates that species "thrown together by chance" are not very likely to survive together over long periods. Even larger food nets do not show significantly different outcomes and prove how extraordinary and complicated natural diversity is. In order to produce such a coexistence of randomly selected species—as the experiment does—models require additional information about biological processes or restrictions on the assumptions. Another explanation for the observed coexistence is a slow extinction that takes longer than the observation time. Simulated species survive a comparable period of time before they die out eventually. Interestingly, it can be stated that the same models allow the survival of several species in equilibrium and thus do not follow the so-called competitive exclusion principle. This state of equilibrium is more fragile, however, to changes in nutrient supply than the oscillating coexistence. Overall, the studies show, that having a diverse system means that population numbers are probably oscillating, and on the other hand oscillating population numbers stabilize a food web both against demographic noise as well as against changes of the habitat. Model predictions can certainly not be converted at their face value into policies for real ecosystems. But the stabilizing character of fluctuations should be considered in the regulations of animal populations.

Contexts and Factors Associated with Bullying

Introduction: School violence discloses a phenomenon that has acquired a marked visibility in today's society, becoming a reality in all schools. With these aggressive behaviors comes a new conception, which increasingly reveals a concern for the community, the bullying (Eiras, 2009). Objectives: Tidentify bullying as a health need in schools; identify the factors associated with bullying. Methods: Integrative Literature Review, and were analyzed 7 articles published in MEDLINE, Scientific Electronic Library Online (SciELO), the Online Knowledge Library (B -on) and the Repositório Científico de Acesso Aberto de Portugal (RCAAP), whereas inclusion criteria were established the Portuguese, English and Spanish and the interval 2011-2016. Results: After analyzing the articles selected for the preparation of this monograph, we identified the following contexts and factors associated with bullying. Conclusions: age with higher prevalence, where this phenomenon was found is between 12 and 13 years; gender, where there is no consensus on the influence of the same in bullying behaviors; family and socio-demographic context in which a family environment marked by cohesion and support promotes attitudes of non-violence and socioeconomic status are not directly related to find this type of episode; bullying characteristics, wherein said type of behavior is more verbal bullying; substance use and knowledge.

Relevant Aspects on Teaching Probability and Statistics in Basic General Education

Probability and Statistics were included in the Basic General Education curricula by the Ministry of Public Education (Costa Rica), since 1995. To analyze the teaching reality in these fields, a research was conducted in two educational regions of the country: Heredia and Pérez Zeledón. The survey included university training and updating processes of teachers teaching Statistics and Probability in the schools. The research demonstrated the limited university training in these fields, the dissatisfaction of teachers about it, and the poor support of training institutions to their professional exercise.

Experimental Project on the Safety and the Optimization of the Use of Glyphosate-Based Herbicides in the Grain Sector.

INTRODUCTION: Glyphosate is the most widely applied pesticide worldwide and it is an active ingredient of all glyphosate-based herbicides (GBHs), including in the formulation “Roundup” . It is unclear if the glyphosate present in ground water can be absorbed and translocated in different parts of the pants, particularly wheat plants. This indeed represents an important aspect for productivity (being this a powerful herbicide) and organic certification of the products (the use of glyphosate is not admitted in organic farming and the ubiquitous contamination of glyphosate in water might in theory affect the level of glyphosate in the plants). Overall, epidemiological, in vivo and in vitro studies available in literature present conflicting findings on the safety of glyphosate. METHODS: The work performed for this PhD thesis aimed to experimentally test the root absorption and the eventual translocation of the glyphosate herbicide in the different parts of the wheat plant (Triticum durum) starting from ground water. Furthermore we aimed to experimentally test the effects of the exposure to GBHs at doses of glyphosate considered to be “safe”, the US ADI of 1.75 mg/kg bw/day, defined as the chronic Reference Dose (cRfD) determined by the US EPA, in in vivo models (Sprague-Dawley rats) and in vitro models (Caco2 and L929). RESULTS: All the experimental absorption studies on wheat plants performed have given negative results in terms of the presence of glyphosate or AMPA in the grain of durum wheat. On the other hand the experimental safety studies on in vitro and in vivo models highlighted different effects at doses currently considered safe for humans and with no effects in animals. CONCLUSION: Overall the integration of the findings from absorption in plants and safety studies will serve as solid evidence-base for risk assessment and productive strategies for agriculture.

Dietro le quinte della satira. Rapporti tra cittadini e contadini nel basso Medioevo italiano

Questa tesi indaga la relazione tra la letteratura anticontadina, fiorente in Italia a partire dalla metà del Trecento, e la realtà dei rapporti tra cittadini e contadini nel basso Medioevo italiano, con un’attenzione particolare all’area padana. Al centro dell’analisi vi sono due stereotipi satirici: il rustico ladro nei campi, che attirava su di sé l’odio feroce della classe padronale, e il villano rozzo, che mangiava alimenti poveri e del tutto estranei alla raffinata cultura alimentare cittadina. L’esame delle fonti giudiziarie, soprattutto bolognesi, conferma che l’immagine del rustico ladro aveva un saldo appiglio nella realtà, ma lo avevano anche i lamenti letterari dei contadini, riguardanti la disonestà dei padroni: vi sono infatti processi in cui i rustici riuscirono a dimostrarsi innocenti da accuse rivelatesi infondate o addirittura false. Inoltre, alcuni processi per ingiurie contro i campagnoli, insieme a episodici riferimenti in epistolari governativi e fonti normative, mostrano come il disprezzo per i villani fosse ben radicato a tutti i livelli della società cittadina. Per quanto riguarda la seconda figura – il rustico rozzo – l’esame dei libri di cucina italiani, unitamente alle descrizioni dei grandi banchetti, mostra chiaramente che non solo i prodotti, ma anche intere ricette associate in letteratura al mondo contadino rientravano nell’alimentazione delle élites: non vi era pertanto una rigida separazione tra l’ambito alimentare cittadino e quello campagnolo. La satira aveva dunque un profondo legame con la realtà, in quanto partiva sempre da un dato reale ed esprimeva un sentimento provato da una larga fascia della cittadinanza. Se ne discostava, tuttavia, quando esasperava la subalternità sociale e culturale dei contadini, negando gli evidenti aspetti di complementarità e integrazione di quel rapporto città-campagna che vedeva la prima in posizione dominante, ma la seconda tutt’altro che passiva o inerme.

Sleep disorders in Multiple System Atrophy: a longitudinal study

Introduction: A higher frequency of sleep and breathing disorders in Multiple System Atrophy (MSA) populations is documented in literature. The analysis of disease progression and prognosis in patients with sleep and breathing disorders could shed light on specific neuropathology and pathophysiology of MSA. Objective: To characterize sleep disorders and their longitudinal modifications during disease course in MSA patients, and to determine their prognostic value. Methods: This is a retrospective and prospective cohort study including 182 MSA patients (58.8% males). Type of onset was defined by the first reported motor or autonomic symptom/sign related to MSA. The occurrence of symptoms/signs and milestones of disease progression and their latency were collected. REM sleep behaviour disorder (RBD) and stridor were video-polysomnography (VPSG)-confirmed. VPSG recordings were analysed in a standardized fashion during the disease course. Survival data were based on time to death from the first symptom of disease. Results: Isolated RBD represented the first MSA symptom in 30% of patients, preceding disease onset according to international criteria with a median of 3(1–5) years. Patients developing early stridor or presenting with RBD at disease onset showed a more rapid and severe disease progression. These features had independent negative prognostic value for survival. Sleep architecture was characterized by peculiar features which could represent negative markers in MSA prognosis. Patients with stridor treated with tracheostomy showed a reduced risk of death. Conclusions: This is one of the first studies focusing on longitudinal progression of sleep in MSA. Sleep disorders are key features of disease, playing a role in presentation, prognosis and progression. In our MSA cohort, RBD represented the most frequent mode of disease presentation. Moreover, some specific clinical and instrumental sleep features could represent a hallmark of MSA and could be involved in prognosis and, in particular, in sudden death and death during sleep.
