Samuel Beckett and the Writers of Port-Royal
No full textIt has been observed that ‘the literary influences on Beckett have been far more important than has been acknowledged, and more important indeed, than the philosophical influences’ (Smith 2002: 3). The truth of this statement is evidenced by the description that scholars have given of Samuel Beckett’s relationship to seventeenth century French classicism. To date, critical interest has been limited for the most part to the figure of the philosopher René Descartes on the (fragile) grounds that Beckett was exclusively concerned with the Cartesian imperative of clarity and order, the fundamental dualism between body and mind, and Nominalism.
Together with the assumption that Beckett’s vision was essentially Cartesian, his literary filiation with Pascal was suggested by critics, but only in terms of Beckett’s formal approach to the theatre. In his short article on En attendant Godot in 1953, the playwright Jean Anouilh was among the first reviewers to suggest that Beckett’s drama synthesizes the encounter between ‘classicism’ and a ‘modern’ form of art. It is well known that Beckett retained a lifelong admiration for Pascal – indeed, Pascal was one of his ‘old chestnuts’ (Knowlson 1997: 653). Little attention has been paid, however, to the originality of Pascal’s thought, the specific nature of his prose, and the impact these might have had upon Beckett’s mature work, especially the trilogy and the subsequent short prose. Yet, in the literary and philosophical context of post-war France, Beckett’s filiation with Pascal, their corresponding preoccupations, were evident to his contemporaries, who identified Pascal as an underlying presence in his works
Irony and Mockery in the Religious Work of Blaise Pascal
No full text85 p.A brilliant mathematician and scientist, Blaise Pascal is also famous for his works of religious philosophy. The author discuses how he used irony and mockery in his discussion of Christian faith
Ironie et Raillerie dans l'Oeuvre Religieuse de Blaise Pascal
No full text85 p.Blaise Pascal stands as one of the leading voices in both religion and literature in the Seventeenth Century. The author considers whether the tone of mockery and irony in the Provincial Letters is appropriate to Pascal’s overall intent and to the Christian context of his work. The author compares Pascal’s writing to Biblical passages that employ mockery and to similar themes found in Plato. Text in French
Jonathan’s Rust Adventures and the Quest for the Numerically Stable Soft-Sphere Integrator
No full textIn this thesis I will implement a numerically stable soft-sphere collision model using Hooke’s Law as the restoring force. This model allows choosing a desired coefficient of restitution and maximum penetration depth in order to generate appropriate values for the spring constant and damping. Then I will explore the applicability of various languages to the field of kD-tree based N-body simulations, concluding that Rust is competitive in both the time and memory usage to C/C++, which are the languages traditionally used for high-performance applications. Additionally, I found that the usage of higher-level languages like Java come at significant time or memory usage costs, making them of little value in the field of large astrophysics simulations. Lastly, as soft-sphere simulations require much smaller time steps for integration compared to hard-spheres, I implemented and benchmarked a priority-queue based adaptive time step system to only take the small time steps when needed. The benchmarks showed a significant speedup compared soft-sphere simulations without this adaptive time step method at roughly 8x faster. In direct particle-particle testing, the adaptive time step showed that with as little as 15 steps during a collision, which the adaptive time step method allows me to set, stable collision handling can be achieved across a spectrum of impact speeds and particle size ratios
Using Fiber Bragg Grating Sensors to Quantify Temperature Non-Uniformities in Plasmonic Catalyst Beds under Illumination
No full textDistinguishing between photothermal and non-thermal contributions is essential in plasmon catalysis. Use of a tailored optical temperature sensor based on fiber Bragg gratings enabled us to obtain an accurate temperature map of an illuminated plasmonic catalyst bed with high spatiotemporal resolution. Its importance for quantification of the photothermal and non-thermal contributions to plasmon catalysis is demonstrated using a Ru/Al2O3 catalyst. Upon illumination with LEDs, we measured temperature differences exceeding 50 °C in the top 0.5 mm of the catalyst bed. Furthermore, we discovered differences between the surface temperature and the temperature obtained via conventional thermocouple measurements underneath the catalyst bed exceeding 200 °C at 2.6 W cm−2 light intensity. This demonstrates that accurate multi-point temperature measurements are a prerequisite for a correct interpretation of catalysis results of light-powered chemical reactions obtained with plasmonic catalysts.ImPhys/Optic
Semi-Supervised Image Classification based on a Multi-Feature Image Query Language
No full textThe area of Content-Based Image Retrieval (CBIR) deals with a wide range of research disciplines. Being closely related to text retrieval and pattern recognition, the probably most serious issue to be solved is the so-called \semantic gap". Except for very restricted use-cases, machines are not able to recognize the semantic content of digital images as well as humans.
This thesis identifies the requirements for a crucial part of CBIR user interfaces, a multimedia-enabled query language. Such a language must be able to capture the user's
intentions and translate them into a machine-understandable format. An approach to tackle this translation problem is to express high-level semantics by merging low-level image features. Two related methods are improved for either fast (retrieval) or accurate(categorization) merging.
A query language has previously been developed by the author of this thesis. It allows the formation of nested Boolean queries. Each query term may be text- or content-based and the system merges them into a single result set. The language is extensible by arbitrary new feature vector plug-ins and thus use-case independent.
This query language should be capable of mapping semantics to features by applying machine learning techniques; this capability is explored. A supervised learning algorithm based on decision trees is used to build category descriptors from a training set. Each resulting \query descriptor" is a feature-based description of a concept which is comprehensible and modifiable. These descriptors could be used as a normal query and return a result set with a high CBIR based precision/recall of the desired category. Additionally, a method for normalizing the similarity profiles of feature vectors has been
developed which is essential to perform categorization tasks.
To prove the capabilities of such queries, the outcome of a semi-supervised training session with \leave-one-object-out" cross validation is compared to a reference system. Recent work indicates that the discriminative power of the query-based descriptors is similar and is likely to be improved further by implementing more recent feature vectors
RAMÓN Society Ltd. Consumption and creation in the aesthetics of Ramón Gómez de la Serna.
No full textThis article will study the creative process of Ramón Gómez de la Serna taking into account the intertwining of the practices of consumption and production of the capitalist system and the literary practices and aesthetic conceptions of this author. Our analysis proposes how Gómez de la Serna understands the mechanisms at play in the marxists analysis of the fetishism of the commodity as aesthetic tools for the creation of literary images. As an extension of this approach and taking as a departing point the analysis of the two editions of El rastro (1914 and 1931), our exploration will cover the creative role of Gómez de la Serna’s own understanding of the nature of his books as commodities.Peer reviewe

Reading acts of narrative appropriation: four instances of fraudulent memoir
No full textPhDThis thesis examines acts of narrative appropriation, the telling of purportedly‘authentic’ life stories by those for whom the stories are not theirs to tell. This
misuse or subversion of genre - the discipline of historical writing and the category
of autobiography - becomes a means for cultural, social and political dissimulation,
and the analysis focuses both on the act: the event, trespass, or ‘theft’ of another’s
life story, and on the cultural meaning that this event reveals. These narrative acts
are approached theoretically through discussions of what it means to be an author, a
reader, and through the consideration of literary and social genre, category and form.
In exploring identities at particular risk of appropriation, this thesis shows how
fraudulent appropriated narratives affect our reading of the world, and in turn
influence our perception of already marginalized social groups. My primary
examples include prostitution ‘narratives’, Native North American ‘memoir,’ and
fraudulent Holocaust survivor ‘testimony,’ with each text providing decoded
evidence of ‘genre-bending’ exhibiting a social and political intent. These works
seek to be read as authentic personal narratives, as autobiography, and that is how
they have been presented to the reader. However, they are imposters – fictional tales
desiring the elevated status of historical authenticity and willing to bend the rules
and contracts of genre to achieve their end. Here the appearance of authenticity is
achieved through the use of cultural and social ‘myth,’ or perceptions of cultural
identity, and as such its fraudulent construction is first and foremost a social act,
with a social and economic motivation. As this thesis concludes, these texts are
most successful when their own political and social ideologies echo and confirm that
of the readership; when their subjects, the fraudulent ‘I’ at the center of the text is
also a performative elaboration of cultural belief
Attitudes and Performance: An Analysis of Russian Workers
No full textThis paper investigates the relationship between locus of control and performance among Russian employees, using survey data collected at 28 workplaces in 2002 in Taganrog and at 47 workplaces in 2003 in Ekaterinburg. We develop a measure that allows us to categorize the Russian employees participating in our survey as exhibiting an internal or external locus of control. We then assess the extent to which there are significant differences between “internals” and “externals” in work-related attitudes that may affect performance. In particular, we focus on (1) attitudes about outcomes associated with hard work, (2) level of job satisfaction, (3) expectation of receiving a desired reward, and (4) loyalty to and involvement with one’s organization. In each case we identify where gender and generational differences emerge. Our main objective is to determine whether Russian employees who exhibit an internal locus of control perform better than employees with an external locus of control. Our performance measures include earnings, expected promotions, and assessments of the quantity and quality of work in comparison to others at the same organization doing a similar job. Controlling for a variety of worker characteristics, we find that (1) individuals who exhibit an internal locus of control perform better, but this result is not always statistically significant; (2) even among “internals,” women earn significantly less than men and have a much lower expectation of promotion; (3) even among “internals,” experience with unemployment has a negative influence on performance.locus of control, Russia, motivation, performance, gender
