Experimental investigation of catalytic and non-catalytic surface reactions on SiO2 thin films with shock heated oxygen gas

The present study is to investigate the interaction of strong shock heated oxygen on the surface of SiO2 thin film. The thermally excited oxygen undergoes a three-body recombination reaction on the surface of silicon dioxide film. The different oxidation states of silicon species on the surface of the shock-exposed SiO2 film are discussed based on X-ray Photoelectron Spectroscopy (XPS) results. The surface morphology of the shock wave induced damage at the cross section of SiO2 film and structure modification of these materials are analyzed using scanning electron microscopy and ion microscopy. Whether the surface reaction of oxygen on SiO2 film is catalytic or non-catalytic is discussed in this paper.

Angular dependence of domain wall resistivity in artificial magnetic domain structures.

We exploit the ability to precisely control the magnetic domain structure of perpendicularly magnetized Pt/Co/Pt trilayers to fabricate artificial domain wall arrays and study their transport properties. The scaling behavior of this model system confirms the intrinsic domain wall origin of the magnetoresistance, and systematic studies using domains patterned at various angles to the current flow are excellently described by an angular-dependent resistivity tensor containing perpendicular and parallel domain wall resistivities. We find that the latter are fully consistent with Levy-Zhang theory, which allows us to estimate the ratio of minority to majority spin carrier resistivities, rho downward arrow/rho upward arrow approximately 5.5, in good agreement with thin film band structure calculations.

Study on variable capacitance diode of (p)nc-Si : H/(n)c-Si heterojunction

Hydrogenated nanocrystalline silicon (nc-Si:H) layers of boron-doped increasing step by step was deposited on n-type crystalline silicon substrate using Plasma Enhanced Chemical Vapor Deposition (PECVD) system. After evaporating Ohm contact electrode on the side of substrate and on the side of nc-Si:H film, a structure of electrode/ (p)nc-Si:H/(n)c-Si/electrode was obtained. It is confirmed by electrical measurement such as I-V curve, C-V curve and DLTS that this is a variable capacitance diode. (C) 2003 Elsevier Science Ltd. All rights reserved.

Azione destabilizzante e impegno politico. Le figure femminili tra il giallo e il nero Italiani dal 1980 a oggi

My thesis analyses female figures in Italian crime fiction since 1980, from narratological, sociological and gender-studies perspectives. It considers the narrative structure of the giallo and the noir, taking into account the difficulties, particularly in Italy, of establishing what noir fiction is and if/how it is possible to frame it in a specific narrative scheme. This discourse connects to the extraordinary success of Italian giallo and noir fiction over the past fifteen-twenty years. In this scenario, I examine the place of female writers in relation to this phenomenon, especially since the 1980s: in terms of the level of visibility/acceptance of their work, in a narrative space traditionally considered as a male territory, and with regard to their writings, which introduce different narrative perspectives. Specifically, I consider selected texts by leading female Italian writers, in which female elements (writers/characters) become destabilizing factor both on the narrative level, by undermining the schemes of ‘formulaic’ fiction, and on the political one, through their implicit potential (as women) for disrupting the rigid models inherited from processes of social conditioning and from political structures. In terms of gender identities, such texts offer scope to question conventional social constructions of the subject: by empowering the female narrative voice and by embodying it in characters (investigators/killers) traditionally personified by male figures. These texts offer themselves as a critical space where, potentially, readers can rethink static gendered relationships and stereotypical symbolical categories.

The redemption of the gaze: the crisis of observation in the "fin de siècle" and the advent of cinema

The intention of this article is not to affirm, but rather to question wether it is possible to speak of a loss of the ability to gaze in the context of the nineteenth century and especially in the context of the fin de siècle, in the bosom of the epistemological crisis that beset the Turn of the Century. And very especially, this article tries to question about the impact this crisis had, perhaps, in the birth of cinema. Is in this context that arises the work of Marey and the advent of the cinematograph of the Lumière brothers in the fin de siècle Europe, both of them showing a deep faith in a mechanical apparatus that would allow the redemption of a battered gaze. And it seems to be a dream that continues over time through the tradition of shooting the everyday life.

The discursive turn in policy analysis and the validation of policy stories

This paper is concerned with the language of policy documents in the field of health care, and how ‘readings’ of such documents might be validated in the context of a narrative analysis. The substantive focus is on a comparative study of UK health policy documents (N=20) as produced by the various assemblies, governments and executives of England, Scotland, Wales and Northern Ireland during the period 2000-2009. Following an identification of some key characteristics of narrative structure the authors indicate how text-mining strategies allied with features of semantic and network analysis can be used to unravel the basic elements of policy stories and to facilitate the presentation of data in such a way that readers can verify the strengths (and weaknesses) of any given analysis – with regard to claims concerning, say, the presence, absence, or relative importance of key ideas and concepts. Readers can also ‘see’ how the different components of any one story might fit together, and to get a sense of what has been excluded from the narrative as well as what has been included, and thereby assess the reliability and validity of interpretations that have been placed upon the data.

Reality status evaluations in mediated experiences /

This paper explores the cognitive functions of the Reality Status Evaluation (RSE) system in our experiences of narrative mediated messages (NMM) (fictional, narrative, audio-visual one-way input and moving picture messages), such as fictional TV programs and films. We regard reality in mediated experiences as a special mental and emotional construction and a multi-dimensional concept. We argue that viewers' reality sense in NMM is influenced by many factors with "real - on" as the default value. Some of these factors function as primary mental processes, including the content realism factors of those messages such as Factuality (F), Social Realism (SR), Life Relevance (LR), and Perceptual Realism - involvement (PR), which would have direct impacts on reality evaluations. Other factors, such as Narrative Meaning (NM), Emotional Responses, and personality trait Absorption (AB), will influence the reality evaluations directly or through the mediations of these main dimensions. I designed a questionnaire to study this theoretical construction. I developed items to form scales and sub-scales measuring viewers' subjective experiences of reality evaluations and these factors. Pertinent statistical techniques, such as internal consistency and factorial analysis, were employed to make revisions and improve the quality of the questionnaire. In the formal experiment, after viewing two short films, which were selected as high or low narrative structure messages from previous experiments, participants were required to answer the questionnaire, Absorption questionnaire, and SAM (Self-Assessment Manikin, measuring immediate emotional responses). Results were analyzed using the EQS, structural equation modeling (SEM), and discussed in terms oflatent relations among these subjective factors in mediated experience. The present results supported most of my theoretical hypotheses. In NMM, three main jactors, or dimensions, could be extracted in viewers' subjective reality evaluations: Social Realism (combining with Factuality), Life Relevance and Perceptual Realism. I designed two ways to assess viewers' understanding of na"ative meanings in mediated messages, questionnaire (NM-Q) and rating (NM-R) measurement, and its significant influences on reality evaluations was supported in the final EQS models. Particularly in high story stnlcture messages, the effect of Narrative Meaning (NM) can rarely be explained by only these dimensions of reality evaluations. Also, Empathy seems to playa more important role in RSE of low story structure messages. Also, I focused on two other factors that were pertinent to RSE in NMM, the personality trait Absorption, and Emotional Responses (including two dimensions: Valence and Intensity). Final model results partly supported my theoretical hypotheses about the relationships among Absorption (AB), Social Realism (SR) and Life Relevance (LR); and the immediate impact of Emotional Responses on Perceptual Realism cPR).

"Man of science, man of faith" : Lost, consumer agency and the fate/free will binary in the post-9/11 context

In 2004, Lost debuted on ABC and quickly became a cultural phenomenon. Its postmodem take on the classic Robinson Crusoe desert island scenario gestures to a variety of different issues circulating within the post-9II1 cultural consciousness, such as terrorism, leadership, anxieties involving air travel, torture, and globalization. Lost's complex interwoven flashback and flash-forward narrative structure encourages spectators to creatively hypothesize solutions to the central mysteries of the narrative, while also thematically addressing archetypal questions of freedom of choice versus fate. Through an examination of the narrative structure, the significance of technological shifts in television, and fan cultures in Lost, this thesis discusses the tenuous notion of consumer agency within the current cultural context. Furthermore, I also explore these issues in relation to the wider historical post-9/II context.

En marge du surréalisme: poétique du rêve chez Leiris et Queneau

Résumé: Ce mémoire consiste en une étude du récit de rêve chez deux auteurs qui ont fait partie du mouvement surréaliste dans leur jeunesse littéraire : Michel Leiris et Raymond Queneau. Dans ce travail, on tente d’une part de décrire la poétique du rêve chez Leiris et Queneau, par diverses analyses qui empruntent surtout à la narratologie et à la linguistique textuelle. D’autre part, nous mesurons la part d’influence du surréalisme dans la conception du rêve de chacun des deux auteurs. Le premier chapitre présente la conception surréaliste du rêve, plus particulièrement celle d’André Breton, telle qu’elle est exposée dans le premier Manifeste du surréalisme et dans les Vases communicants. Cette synthèse est suivie de l’analyse de quelques récits de rêve de Breton issus du recueil Clair de terre, et du périodique la Révolution surréaliste. Les deuxième et troisième chapitres abordent l’écriture du rêve chez Leiris et Queneau. On étudie d’abord les récits de rêve écrits alors que ces auteurs appartenaient au mouvement surréaliste (1924-1929). Ces textes se trouvent dans leurs journaux intimes et dans la revue la Révolution surréaliste. Sont ensuite étudiées certaines œuvres écrites après la période surréaliste qui contiennent des récits de rêve ou qui exploitent le rêve comme structure narrative. Par ces analyses, ce mémoire tente de montrer la contribution du travail sur le rêve à l’élaboration de la poétique personnelle des auteurs Leiris et Queneau. Mots clefs : récit de rêve, Michel Leiris, Raymond Queneau, surréalisme, littérature française.

Le miroir brisé : le délire à l’œuvre dans Trou de mémoire et L’Antiphonaire d’Hubert Aquin

Ce mémoire aborde la question de la folie dans l’œuvre d’Hubert Aquin, en particulier dans deux romans : Trou de mémoire et L’Antiphonaire. Deux types de désordre de la personnalité font l’objet de l’étude : le délire psychotique dans le cas de Trou de mémoire, et l’épilepsie pour ce qui est de L’Antiphonaire. La question de la maladie mentale ou neurologique est envisagée tant du point de vue thématique que du point de vue structurel. Bien que l’aspect thématique occupe la majeure partie du mémoire, l’analyse de la structure du récit y tient une place importante, l’une des hypothèses de départ étant que le désordre mental affecte la composition narrative des deux romans d’Aquin. Plusieurs sources non littéraires sont utilisées pour apporter des éléments d’analyse susceptibles de confirmer les hypothèses proposées. En plus de faire appel à des sources médicales et à des textes relevant de la psychologie, cette recherche trace un historique de l’épilepsie, en faisant ressortir les différences entre la conception qu’on en avait à l’époque de la Renaissance et celle qui prévaut aujourd’hui. Tout en empruntant à des domaines divers du savoir, cette étude s’intéresse à une question peu traitée par la critique ayant abordé le thème de la folie chez Aquin : celle de ses répercussions sur la structure du récit.

La mise en scène du savoir-faire musical au cinéma

Ce mémoire de recherche-création vise d’abord à inventorier et à analyser les processus et procédés narratifs, rhétoriques et formels grâce auxquels trois films mettent en scène le savoir-faire musical, et particulièrement la situation d’apprentissage de la musique et la relation maître-élève. Ces trois films sont : All That Jazz, de Bob Fosse (1979), Bird, de Clint Eastwood (1988) et Tous les matins du monde, d’Alain Corneau (1991). Au terme de cet inventaire et de cette analyse, nous aurons repéré une dominante thématique : dans ces films, et peut-être au cinéma en général, la musique et l’enseignement de la musique sont représentés sous des traits socio-psychologiques particuliers : d’une part, la possession de l’autre, la soumission, le sacrifice et la perpétuelle insatisfaction. Mais aussi les multiples gratifications dont l’éducation et la formation du corps et de l’esprit sont gages. Il conviendra alors de vérifier une hypothèse : Est-ce que certains modes d’expression cinématographiques — ayant à voir avec certaines pratiques de cadrage, certaines figures du champ- contrechamp, etc. —, et certains modes de narration filmiques n’expliqueraient pas cette capacité du cinéma à mettre en scène les menaces affectives et sociales qui pèsent sur le maître de musique et l’apprenti musicien ? Ce sont ces mêmes processus et procédés, ce même thème et cette même hypothèse, qui seront explorés dans un scénario de long métrage, en faisant cette fois-ci confiance à la capacité de problématisation de l’écriture poétique.
