In Between Cultures : Franco-American Encounters in the Work of Edith Wharton / Mellan kulturer : Fransk-Amerikanska möten i Edith Whartons verk

Strääf, Maria January 2008 (has links)
This thesis is a study of how the American author Edith Wharton (1862-1937) in a number of novels and short stories written between 1876 and 1937 depicts cultural encounters between Americans and Europeans, mostly Frenchmen. Chiefly concerned with Fast and Loose, “The Last Asset”, Madame de Treymes, “Les Metteurs en Scène”, The Custom of the Country and The Age of Innocence, each of which articulates ideas relevant to the theme investigated, the thesis also contains a supplementary discussion of The Reef, The Glimpses of the Moon, The Mother’s Recompense and The Buccaneers. Borrowing terms and theoretical perspectives from Pierre Bourdieu and postcolonial literary criticism, particularly Homi Bhabha’s theories about inbetweenness, mimicry and otherness, the study contends through detailed analyses of single works that Wharton’s descriptions of Franco-American encounters are dynamic processes through which the parties involved are made aware of their own and “the other’s” distinguishing qualities and, in some significant cases, reach a heightened state of consciousness resembling Bhabha’s inbetweenness. Wharton’s cultural encounters often involve people with different levels of education and different economic and social positions, which justifies the use of Bourdieu’s method of analyzing the relationship between educational and social status in terms of different kinds of capital. While in her early works Wharton merely intimates the contours of the cultural encounter, in mature works such as Madame de Treymes and The Age of Innocence she views it as a highly complex process the many stages of which are intimated through the use of subtle narratological techniques. Throughout her work Wharton makes intricate use of imagery and keywords, some of them testifying to her interest in anthropology, to suggest the manifold dimensions of the cultural encounter, which is seen as both tempting and repelling. Her accounts of the Franco-American encounter are complexly related to the different phases of the American political and social situation described in her novels. The American experience of the meeting of the ‘old society’ and the ‘new’ is rendered even more complex by being seen as the background against which Europeans and Americans negotiate transactions of symbolic and economic capital. In most of her works these lead to tragic or tragic-comic misunderstandings; only in her last, unfinished novel does she describe a full-fledged Euro-American identity, a successful fusion of American and European experiences. / Den här avhandlingen är en studie i hur den amerikanska författarinnan Edith Wharton (1862-1937) i ett antal romaner och noveller skrivna mellan 1876 and 1937 skildrar kulturella möten mellan amerikaner och européer, främst fransmän. Avhandlingen behandlar huvudsakligen verken Fast and Loose, “The Last Asset”, Madame de Treymes, ”Les Metteurs en Scène”, The Custom of the Country and The Age of Innocence, som alla uttrycker idéer om kulturmöten; den innehåller även en kompletterande diskussion av verken The Reef, The Glimpses of the Moon, The Mother’s Recompense and The Buccaneers. Med termer och perspektiv hämtade från Pierre Bourdieu och postkolonial litteraturforskning, främst Homi Bhabhas teorier om in-betweenness (”mellanskap”), mimicry och otherness hävdar studien genom detaljerade analyser av enskilda verk hur Whartons beskrivningar av fransmäns och amerikaners möten är dynamiska processer där i bästa fall båda parter blir medvetna om sin egen och ”den andres” särart, och i vissa fall även når ett intensifierat medvetande som påminner om Bhabhas in-betweenness. Whartons kulturmöten sker oftast mellan personer med olika bildning samt ekonomisk och social position, vilket gör att Bourdieus perspektiv för analys av relationen mellan utbildning och social status som styrd av olika sorters kapital kommer till användning. I sina tidiga berättelser antyder Wharton konturerna av det kulturella mötet, i mogna verk som Madame de Treymes and The Age of Innocence gestaltar hon det som en mycket komplex process vars många skeden antyds via hennes användning av subtil berättarteknik. Alltigenom sina verk tillämpar Wharton ett komplext bildspråk och nyckelord, varav vissa vittnar om hennes intresse för antropologi, som antyder kulturmötets många dimensioner, framställt som samtidigt lockande och frånstötande/avskräckande. Hennes redogörelser av det fransk-amerikanska mötet är komplext relaterat till de olika faser av den amerikanska politiska och sociala situation som beskrivs i hennes berättelser. Den amerikanska erfarenheten av mötet mellan den ”gamla sociala grupperingen” och den ”nya” skildras som mer komplext genom att ses som den bakgrund mot vilken européerna och amerikanerna förhandlar transaktioner av symboliskt och ekonomiskt kapital. I merparten av hennes verk leder dessa transaktioner till tragiska eller tragikomiska missförstånd; bara i hennes sista, ofullbordade roman beskriver hon en fullt utvecklad euroamerikansk identitet, en lyckad sammansmältning av amerikanska och europeiska erfarenheter.

Efficient betweenness Centrality Computations on Hybrid CPU-GPU Systems

Mishra, Ashirbad January 2016 (has links) (PDF)
Analysis of networks is quite interesting, because they can be interpreted for several purposes. Various features require different metrics to measure and interpret them. Measuring the relative importance of each vertex in a network is one of the most fundamental building blocks in network analysis. Between’s Centrality (BC) is one such metric that plays a key role in many real world applications. BC is an important graph analytics application for large-scale graphs. However it is one of the most computationally intensive kernels to execute, and measuring centrality in billion-scale graphs is quite challenging. While there are several existing e orts towards parallelizing BC algorithms on multi-core CPUs and many-core GPUs, in this work, we propose a novel ne-grained CPU-GPU hybrid algorithm that partitions a graph into two partitions, one each for CPU and GPU. Our method performs BC computations for the graph on both the CPU and GPU resources simultaneously, resulting in a very small number of CPU-GPU synchronizations, hence taking less time for communications. The BC algorithm consists of two phases, the forward phase and the backward phase. In the forward phase, we initially and the paths that are needed by either partitions, after which each partition is executed on each processor in an asynchronous manner. We initially compute border matrices for each partition which stores the relative distances between each pair of border vertex in a partition. The matrices are used in the forward phase calculations of all the sources. In this way, our hybrid BC algorithm leverages the multi-source property inherent in the BC problem. We present proof of correctness and the bounds for the number of iterations for each source. We also perform a novel hybrid and asynchronous backward phase, in which each partition communicates with the other only when there is a path that crosses the partition, hence it performs minimal CPU-GPU synchronizations. We use a variety of implementations for our work, like node-based and edge based parallelism, which includes data-driven and topology based techniques. In the implementation we show that our method also works using variable partitioning technique. The technique partitions the graph into unequal parts accounting for the processing power of each processor. Our implementations achieve almost equal percentage of utilization on both the processors due to the technique. For large scale graphs, the size of the border matrix also becomes large, hence to accommodate the matrix we present various techniques. The techniques use the properties inherent in the shortest path problem for reduction. We mention the drawbacks of performing shortest path computations on a large scale and also provide various solutions to it. Evaluations using a large number of graphs with different characteristics show that our hybrid approach without variable partitioning and border matrix reduction gives 67% improvement in performance, and 64-98.5% less CPU-GPU communications than the state of art hybrid algorithm based on the popular Bulk Synchronous Paradigm (BSP) approach implemented in TOTEM. This shows our algorithm's strength which reduces the need for larger synchronizations. Implementing variable partitioning, border matrix reduction and backward phase optimizations on our hybrid algorithm provides up to 10x speedup. We compare our optimized implementation, with CPU and GPU standalone codes based on our forward phase and backward phase kernels, and show around 2-8x speedup over the CPU-only code and can accommodate large graphs that cannot be accommodated in the GPU-only code. We also show that our method`s performance is competitive to the state of art multi-core CPU and performs 40-52% better than GPU implementations, on large graphs. We show the drawbacks of CPU and GPU only implementations and try to motivate the reader about the challenges that graph algorithms face in large scale computing, suggesting that a hybrid or distributed way of approaching the problem is a better way of overcoming the hurdles.

"As if they're daring you to desire them" : En studie av de antika skulpturernas roll i filmen "Call me by your name"

Svärd, Fanny January 2018 (has links)
This Bachelor’s thesis examines the use of ancient bronze statues in the 2017 film Call me by your name by director Luca Guadagnino. Various scenes which feature ancient statues are examined individually using semiotic analysis. The scenes are examined individually, first described on a denotative level, then analyzed on a connotative level. The theoretical stand point is based on the studies of art works in film. Key theoretical concepts used are ”in between-ness” which is a state in which change in narrative is made possible through looking at art, and ”parallels”, a means of which to make art represent the characters in the film. The thesis finds the sculptures in Call me by your name to play a part in affecting the narrative of the film, mainly in regard to the love story between the two lead characters, two men named Elio and Oliver. The acts of looking, examining, and touching the statues in this film help the narrative turn in favor of the lead characters romantic relationship. The thesis argues that the nude bronze sculptures of men from ancient Greece are used in this film as signifiers of desire, timelessness and homoerotic lust.

Novel measures on directed graphs and applications to large-scale within-network classification

Mantrach, Amin 25 October 2010 (has links)
Ces dernières années, les réseaux sont devenus une source importante d’informations dans différents domaines aussi variés que les sciences sociales, la physique ou les mathématiques. De plus, la taille de ces réseaux n’a cessé de grandir de manière conséquente. Ce constat a vu émerger de nouveaux défis, comme le besoin de mesures précises et intuitives pour caractériser et analyser ces réseaux de grandes tailles en un temps raisonnable.<p>La première partie de cette thèse introduit une nouvelle mesure de similarité entre deux noeuds d’un réseau dirigé et pondéré :la covariance “sum-over-paths”. Celle-ci a une interprétation claire et précise :en dénombrant tous les chemins possibles deux noeuds sont considérés comme fortement corrélés s’ils apparaissent souvent sur un même chemin – de préférence court. Cette mesure dépend d’une distribution de probabilités, définie sur l’ensemble infini dénombrable des chemins dans le graphe, obtenue en minimisant l'espérance du coût total entre toutes les paires de noeuds du graphe sachant que l'entropie relative totale injectée dans le réseau est fixée à priori. Le paramètre d’entropie permet de biaiser la distribution de probabilité sur un large spectre :allant de marches aléatoires naturelles où tous les chemins sont équiprobables à des marches biaisées en faveur des plus courts chemins. Cette mesure est alors appliquée à des problèmes de classification semi-supervisée sur des réseaux de taille moyennes et comparée à l’état de l’art.<p>La seconde partie de la thèse introduit trois nouveaux algorithmes de classification de noeuds en sein d’un large réseau dont les noeuds sont partiellement étiquetés. Ces algorithmes ont un temps de calcul linéaire en le nombre de noeuds, de classes et d’itérations, et peuvent dés lors être appliqués sur de larges réseaux. Ceux-ci ont obtenus des résultats compétitifs en comparaison à l’état de l’art sur le large réseaux de citations de brevets américains et sur huit autres jeux de données. De plus, durant la thèse, nous avons collecté un nouveau jeu de données, déjà mentionné :le réseau de citations de brevets américains. Ce jeu de données est maintenant disponible pour la communauté pour la réalisation de tests comparatifs.<p>La partie finale de cette thèse concerne la combinaison d’un graphe de citations avec les informations présentes sur ses noeuds. De manière empirique, nous avons montré que des données basées sur des citations fournissent de meilleurs résultats de classification que des données basées sur des contenus textuels. Toujours de manière empirique, nous avons également montré que combiner les différentes sources d’informations (contenu et citations) doit être considéré lors d’une tâche de classification de textes. Par exemple, lorsqu’il s’agit de catégoriser des articles de revues, s’aider d’un graphe de citations extrait au préalable peut améliorer considérablement les performances. Par contre, dans un autre contexte, quand il s’agit de directement classer les noeuds du réseau de citations, s’aider des informations présentes sur les noeuds n’améliora pas nécessairement les performances.<p>La théorie, les algorithmes et les applications présentés dans cette thèse fournissent des perspectives intéressantes dans différents domaines.<p><p><p>In recent years, networks have become a major data source in various fields ranging from social sciences to mathematical and physical sciences. Moreover, the size of available networks has grow substantially as well. This has brought with it a number of new challenges, like the need for precise and intuitive measures to characterize and analyze large scale networks in a reasonable time. <p>The first part of this thesis introduces a novel measure between two nodes of a weighted directed graph: The sum-over-paths covariance. It has a clear and intuitive interpretation: two nodes are considered as highly correlated if they often co-occur on the same -- preferably short -- paths. This measure depends on a probability distribution over the (usually infinite) countable set of paths through the graph which is obtained by minimizing the total expected cost between all pairs of nodes while fixing the total relative entropy spread in the graph. The entropy parameter allows to bias the probability distribution over a wide spectrum: going from natural random walks (where all paths are equiprobable) to walks biased towards shortest-paths. This measure is then applied to semi-supervised classification problems on medium-size networks and compared to state-of-the-art techniques.<p>The second part introduces three novel algorithms for within-network classification in large-scale networks, i.e. classification of nodes in partially labeled graphs. The algorithms have a linear computing time in the number of edges, classes and steps and hence can be applied to large scale networks. They obtained competitive results in comparison to state-of-the-art technics on the large scale U.S.~patents citation network and on eight other data sets. Furthermore, during the thesis, we collected a novel benchmark data set: the U.S.~patents citation network. This data set is now available to the community for benchmarks purposes. <p>The final part of the thesis concerns the combination of a citation graph with information on its nodes. We show that citation-based data provide better results for classification than content-based data. We also show empirically that combining both sources of information (content-based and citation-based) should be considered when facing a text categorization problem. For instance, while classifying journal papers, considering to extract an external citation graph may considerably boost the performance. However, in another context, when we have to directly classify the network citation nodes, then the help of features on nodes will not improve the results.<p>The theory, algorithms and applications presented in this thesis provide interesting perspectives in various fields.<p> / Doctorat en Sciences / info:eu-repo/semantics/nonPublished

Deterritorialized male subjectivity : liminality, in-betweenness, and becoming in migrant literary and cultural contexts

Zamanpour, Ali 12 1900 (has links)
Cette thèse résulte de la recherche d’un sujet dépourvu de tout repère à ses liens relationnels. Elle rompt les territorialités de la narration et va au-delà des seuils du sujet, à travers des mouvements rhizomiques et en suivant les lignes littéraires et culturelles qui permettent d’échapper aux forces emprisonnantes d’assujettissement. Cette étude trait des sites marginalisés de la transformation et de la dislocation, en passant par les sites de la résistance et de la décolonisation. Ma lecture de la littérature migrante et, des littératures indigènes, la déterritorialisation et la décolonisation s’entrelacent en trois sites majeurs au sein: la liminalité, l’intermédiaritéé et le devenir. Ces sites ne représentent pas seulement les formes esthétiques innovantes qui traversent les seuils de l’identité dans notre culture contemporaine, mais ils assistent aussi ce projet à son but ultime de réinventer et de réarranger la relation entre le soi et l’autre vers de nouveaux débuts. Cette nouvelle perspective munie de l’éthique de s’engager dans la situation, s’abstient d’émettre un jugement et entend prévoir des possibilités d’une transformation révolutionnaire aux niveaux politique, social et économique. Dans ce projet, les mouvements de déterritorialisation émergent dans les écrits et les productions artistiques de Richard Mosse, Chris Abani, Rawi Hage, Leslie Marmon Silko et Thomas King et fournissent les possibilités d’une certaine réflexion sur les seuils de différents sujets masculins en crise. Ce projet s’adresse, en premier lieu, à la Chose sous-jacente qui se déplace entre-deux territoires et perturbe le désire de capturer son essence; en revanche, suivant Deleuze et Guattari, elle se déplace avec les mouvements nomadiques des sujets masculins qui deviennent des simulacres assujettis dans divers sites de désapprentissage. À titre d’exemple, ces sites de désapprentissages illustrés dans Incoming et The Castle de Richard Mosse dissocient la matérialité du déplacé de son image et informe le discours sur les façons à travers lesquelles l’existence est mise en danger, limitée et violée par la représentation. À travers GraceLand d’Abani, ce projet examine des modes de liminalité et des cérémonies d’initiation et reconnaît les expériences vécues des sujets masculins dans des structures culturelles différentes. Dans les romans de Rawi Hage, j’explore les façons à travers lesquelles la masculinité s’arrange ou se réarrange, de façon créative, dans des actes de performance. Cette thèse revient sur le sujet de la liminalité par le biais de Ceremony de Silko et de la narration post-apocalyptique de l’identité de Thomas King. L’analyse aborde certain des enjeux que les hommes indigènes et ceux qui affirment les identités masculines doivent affronter. Ainsi, dans le dernier chapitre, la convergence harmonieuse des voix indigènes et des littératures indigènes et migrantes situe ces lignes de fuite qui pourraient se rejoindre ou refuser de se croiser, ou se désintégrer dans le flot de la violence. / This dissertation stems from the search for a subject without reference to the webs of relations that hold it. Through rhizomatic movements, it breaks territorialities of narrative and moves beyond the subject’s thresholds by following literary and cultural lines of escape away from imprisoning forces of subjugation. The investigation flows along marginalized sites of transformation and displacement and through sites of resistance and decolonization. In my readings of migrant and Indigenous literatures, deterritorialization and decolonization intertwine at three major sites: liminality, in-betweenness, and becoming. These sites are not only innovative aesthetic forms that cross the threshold of identity in our contemporary culture; they also participate in the project of reinventing and rearranging the relation of self and other toward new beginnings. The new perspectives that are offered engage ethically, avoid judgment, and foresee the possibilities for revolutionary political, social, and economic transformation. The movements of deterritorialization that emerge within the writings and artistic production of Richard Mosse, Chris Abani, Leslie Marmon Silko, Thomas King and Rawi Hage provide possibilities for reflection at the thresholds of different male subjects in crisis. This project first addresses the underlying Thing that moves in between territories and confounds the desire to capture its essence; instead, following Deleuze and Guattari, it moves along with the male subjects’ nomadic movements as they become desubjectified simulacra in various sites of unlearning. In Richard Mosse’s Incoming and The Castle, for example, such a site of unlearning separates the materiality of the displaced from its image and informs discourse about the ways in which representation endangers, limits and violates existence. Through Abani’s GraceLand, this project further investigates modes of liminality and initiation ceremonies and acknowledges the lived experiences of male subjects in different cultural structures. In Rawi Hage’s novels, I explore the ways masculinity arranges or rearranges itself creatively in acts of performance. The dissertation also again turns to liminality by way of Leslie Marmon Silko’s Ceremony, and Thomas King’s post-apocalyptic narrative of identity. In this way, the harmonious conjunction of Indigenous voices and Indigenous and migrant literatures attempts to locate where these lines of escape might come together, refuse to cross, or crumble back upon themselves in flows of violence.

The internal dynamics of terrorist cells: a social network analysis of terrorist cells in an Australian context

Koschade, Stuart Andrew January 2007 (has links)
The rise of the 21st Century Islamic extremist movement, which was mobilised by the al-Qaeda attacks of and responses to September 11, 2001, heralds a new period in the history of terrorism. The increased frequency and intensity of this type of terrorism affects every nation in the world, not least Australia. Rising to meet the challenges posed by terrorism is the field of terrorism studies, the field which aims at understanding, explaining, and countering terrorism. Despite the importance of the field, it has been beleaguered with criticisms since its inception as a response to the rise of international terrorism. These criticisms specifically aim at the field's lack of objectivity, abstraction, levels of research, and levels of analysis. These criticisms were the impetus behind the adoption of the methodology of this thesis, which offers the distinct ability to understand, explain, and forecast the way in which terrorists interact within covert cells. Through social network analysis, this thesis examines four terrorist cells that have operated in or against Australia. These cells are from the groups Hrvatsko Revolucionarno Bratstvo (Croatian Revolutionary Brotherhood), Aum Shinrikyo (Supreme Truth), Lashkar-e-Taiba (Army of the Pure), and Jemaah Islamiyah (Islamic Community) and operated between 1963 and 2003. Essentially, this methodology attempts to discover, map, and analyse the interaction within the cells during the covert stage of their respective operations. Following this, the results are analysed through the traditional social network analysis frameworks to discover the internal dynamics of the cell and identify the critical nodes (leaders) within the cells. Destabilisation techniques are subsequently employed, targeting these critical nodes to establish the most effective disruption techniques from a counter-terrorism point of view. The major findings of this thesis are: (1) that cells with a focus on efficiency rather than covertness were more successful in completing their objectives (contrary to popular belief); and (2) betweenness centrality (control over the flow of communication) is a critical factor in identifying leaders within terrorist cells. The analysis also offered significant insight into how a Jemaah Islamiyah cell might operate effectively in Australia, as well as the importance of local contacts to terrorist operations and the significance of international counter-terrorism cooperation and coordination.
