De série monde à série phénomène : analyse diégétique et de la réception de Xena la guerrière (1995-2001)

Ce mémoire propose d’analyser une série phénomène à travers le concept de série monde développé dans les études télévisuelles et cinématographiques. Notre objet d’analyse est Xena la guerrière (Syndication 1995-2001), une série des années 1990 connue à l’ère contemporaine pour son phénomène de fandom autour de la série et des personnages Xena et Gabrielle. Les séries de la fin des années 1990 s’inscrivent dans une ère de transition, où numérique et mutations narratives vont participer à la création d’objets denses et complexes. Nous tenterons d’établir un parallèle entre la structure d’une série télévisée et sa réception qui reposent toutes les deux sur une logique de densification, à observer sous différentes formes : l’extension, la continuité et la dérivation, ainsi que sur deux niveaux : le texte et le fandom. L’analyse diégétique de la série nous permettra d’établir une conception de la série comme une expérience dense et complexe qui invite et suggère une pluralité interprétative. Les spectateurs/fans investissent l’objet de différentes façons jusqu’à produire des lectures riches et variées. Définir un phénomène sériel reviendrait donc à s’intéresser à cette corrélation : producteurs, texte, fans et contextes, qui permet l’expansion de l’objet dans de multiples directions. L’analyse de Xena la guerrière autour d’une logique de densification nous permettrait de mieux comprendre certains phénomènes de fandom autour de séries contemporaines.This dissertation proposes an analysis of a series phenomenon through the concept of world series developed in television and film. Our object of analysis is Xena: Warrior Princess (Syndication 1995-2001), a television series from the 1990s known in the contemporary era for the phenomenon of fandom created around the series and characters Xena and Gabrielle. The series of the late 1990s are part of an era of transition, where digital and narratives mutations come together in the creation of dense and complex objects. We will try to draw a parallel between the structure of a television series and its reception, both of which are based on a logic of densification, to be observed in different forms: extension, continuity, and derivation, as well as on two levels: the text of Xena and the fandom of Xena. The diegetic analysis of the series will allow us to establish the conception and origins of the series as something dense and complex that invites and suggests a plurality of interpretations. Spectators/fans invest time and effort in the show in a variety of ways to produce rich and varied interpretations and fandom content. Defining a serial phenomenon would therefore take us back to examining the correlation of: producer, text, fans, and context, which allows this expansion of the series in multiple directions. The analysis of Xena: Warrior Princess around a logic of densification will allow us to better understand certain phenomena of fandom around contemporary series

The use of the eigenvectors of the spectral matrix. Seismic application

The spectral matrix filtering is a technique Chat enables separation of data obtained front an antenna into a signal part and a noise part . In certain circumstances it has been use for wave separation . The aim of the process is to build models of propagation at the antenna level . Using these models each wave is then estimated by a least-squares method . When this process is applied to seismic data, the spectral matrix has to he estimated in a special way . The estimation of models is particularly efficient using a time-domain representation of the eigenvectors of the spectral matrix . Two new separation processes are proposed, the matched model and the tapered model . The scalar product of the two différent waves is a parameter to be used when estimating the performance of the process . Application to four différent types of seismic data illustrates the efficiency of this type of filtering .La matrice spectrale est un outil utilisé pour séparer les signaux reçus sur une antenne en une partie signal et une partie bruit. Dans certains cas elle est utilisée pour séparer les ondes constituant la partie signal. La méthode consiste à estimer des modèles de propagation de ces ondes au niveau de l'antenne; les signaux sont alors obtenus par estimation aux moindres carrés. Appliquée à la sismique, cette méthode nécessite des opérations particulières d'estimation de la matrice spectrale. La détermination des modèles s'avère particulièrement efficace lorsque l'on utilise la représentation des vecteurs propres (de la matrice spectrale) dans le domaine temporel

Traitement de données vectorielles multicapteurs. Application à l'acoustique sous-marine

L'utilisation de données vectorielles multi-capteurs en acoustique sous-marine offre de nouvelles possibilités de séparation d'ondes. Nous proposons d'utiliser séquentiellement le traitement vectoriel (polarisation) puis le traitement multi-capteurs (antenne). Pour l'étude de la propagation marine, sismique et acoustique en Ultra Basses Fréquences (U.B.F., entre 1 et 50 Hz), une estimation de la contribution du sous-sol sur des données réelles basée sur ce traitement séquentiel illustre l'intérêt de cette méthode

Health services research into postnatal depression : results from a preliminary cross-cultural study

Background: Little is known about the availability and uptake of health and welfare services by women with postnatal depression in different countries. Aims: Within the context of a cross- cultural research study, to develop and test methods for undertaking quantitative health services research in postnatal depression. Method: Interviews with service planners and the collation of key health indicators were used to obtain a profile of service availability and provision. A service use questionnaire was developed and administered to a pilot sample in a number of European study centres. Results: Marked differences in service access and use were observed between the centres, including postnatal nursing care and contacts with primary care services.Rates of use of specialist services were generally low.Common barriers to access to care included perceived service quality and responsiveness. On the basis of the pilot work, a postnatal depression version of the Service Receipt Inventory was revised and finalised. Conclusions: This preliminary study demonstrated the methodological feasibility of describing and quantifying service use, highlighted the varied and often limited use of care in this population, and indicated the need for an improved understanding of the resource needs and implications of postnatal depression

Rapid sediment deposition and fine-scale strata formation in the Hudson estuary

Author Posting. © American Geophysical Union, 2004. This article is posted here by permission of American Geophysical Union for personal use, not for redistribution. The definitive version was published in Journal of Geophysical Research 109 (2004): F02004, doi:10.1029/2003JF000096.A 9 month time series of tripod-mounted optical and acoustic measurements of sediment concentration and bed elevation was used to examine depositional processes in relationship to hydrodynamic variables in the Hudson River estuary. A series of cores was also taken directly under and adjacent to the acoustic measurements to examine the relation between the depositional processes and the resulting fine-scale stratigraphy. The measurements reveal that deposition occurs as a result of sediment flux convergence behind a salinity front and that the accumulation rates are sufficient to deposit up to 25 cm of new high-porosity sediment in a single ebb-tidal phase. Subsequent dewatering and erosion reduces the thickness of the initial deposit to several centimeters. These depositional events were only observed on spring tides. Ten depositional events during two spring tidal cycles produced a seasonal deposit of 18 cm, consistent with estimates of seasonal deposition from cores. A proxy for near-bed suspended grain size variations was estimated from the combined acoustic and optical measurements, implying that the erosional processes resuspend only the finer-grained sediments, thus leaving behind silt and very fine grained sand beds. The thickness of the deposited homogenous clayey silt beds, and the vertical separation between beds interlaminated with silt and very fine sand, are roughly consistent with the acoustic measurements of changes in bed elevations during deposition and erosion. The variability in individual bed thickness is the result of variations of processes over an individual tidal cycle and is not a product of variations over the spring neap fortnightly timescale.The authors would like to acknowledge the Hudson River Foundation, who provided funding for this work under grant 009/00A

Inpatient mother-and-child postpartum psychiatric care: factors associated with improvement in maternal mental health.

International audiencePURPOSE: This study assessed the underexplored factors associated with significant improvement in mothers' mental health during postpartum inpatient psychiatric care. METHODS: This study analyzed clinical improvement in a prospective cohort of 869 women jointly admitted with their infant to 13 psychiatric Mother-Baby Units (MBUs) in France between 2001 and 2007. Predictive variables tested were: maternal mental illness (ICD-10), sociodemographic characteristics, mental illness and childhood abuse history, acute or chronic disorder, pregnancy and birth data, characteristics and mental health of the mother's partner, and MBU characteristics. RESULTS: Two thirds of the women improved significantly by discharge. Admission for 25% was for a first acute episode very early after childbirth. Independent factors associated with marked improvement at discharge were bipolar or depressive disorder, a first acute episode or relapse of such an episode. Schizophrenia, a personality disorder, and poor social integration (as measured by occupational status) were all related to poor clinical outcomes. DISCUSSION: Most women improved significantly while under care in MBUs. Our results emphasize the importance of the type of disease but also its chronicity and the social integration when providing postpartum psychiatric care

Men's experiences of having a partner who requires Mother and Baby Unit admission for first episode postpartum psychosis

Aims The aim of this study was to explore the experiences of men during their partner's admission to a Mother and Baby Unit for first episode postpartum psychosis. Background Postpartum psychosis can be life-changing for women, however little is known about the impact on their partners or their partners' needs. Design An Interpretative Phenomenological Analysis approach was used to analyse interview transcripts. Methods Semi-structured interviews were conducted with seven participants. Interviews were conducted in 2014–2015. Findings Two main themes were identified: ‘What the f*** is going on?’ and ‘Time to figure out how your family works’. Partners experienced shock and confusion during postpartum psychosis onset. Most felt hospital admission was beneficial, although there were barriers to accessing help and involvement in their partner's care. A process of understanding changes to roles, relationships and family identity was described. Loss was a common experience, with a potentially lasting impact. Conclusions Men reported a range of challenging and positive experiences associated with their partner's postpartum psychosis. Improvements are needed in awareness of postpartum psychosis, access to appropriate services and support of partners

Dose-Dependent Effect of Rosuvastatin on VLDL–Apolipoprotein C-III Kinetics in the Metabolic Syndrome

OBJECTIVE—Dysregulated apolipoprotein (apo)C-III metabolism may account for hypertriglyceridemia and increased cardiovascular risk in the metabolic syndrome. This study investigated the dose-dependent effect of rosuvastatin on VLDL apoC-III transport in men with the metabolic syndrome

Postnatal depression across countries and cultures : a qualitative study

Background: Postnatal depression seems to be a universal condition with similar rates in different countries. However, anthropologists question the cross-cultural equivalence of depression, particularly at a life stage so influenced by cultural factors. Aims: To develop a qualitative method to explore whether postnatal depression is universally recognised, attributed and described and to enquire into people’s perceptions of remedies and services for morbid states of unhappiness within the context of local services. Method: The study took place in 15 centres in 11 countries and drew on three groups of informants: focus groups with new mothers, interviews with fathers and grandmothers, and interviews with health professionals.Textual analysis of these three groups was conducted separately in each centre and emergent themes compared across centres. Results: All centres described morbid unhappiness after childbirth comparable to postnatal depression but not all saw this as an illness remediable by health interventions. Conclusions: Although the findings of this study support the universality of a morbid state of unhappiness following childbirth, they also support concerns about the cross-cultural equivalence of postnatal depression as an illness requiring the intervention of health professionals; this has implications for future research
