Depuis qu’en 1977, en quatrième de couverture de Fils, Serge Doubrovsky employa le mot « autofiction » pour décrire son roman, les études doubrovskiennes ont eu tendance à se focaliser sur les questions génériques que sous-tendait ce néologisme. Ainsi on a écarté un autre aspect, tout aussi important, de l’œuvre de l’auteur : celui du lien avec le lecteur qui, en plus d’être mis en scène dans chacune des autofictions doubrovskiennes, est associé dès Fils au rapport complexe, inextricable et conflictuel entre les sexes. « J’écris mâle, me lis femelle », dit le narrateur-écrivain ‘Serge Doubrovsky’ – lui qui vivra sous nos yeux une série d’histoires passionnelles avec des compagnes qui sont également ses lectrices. Repris d’épisode en épisode, le rapport entre le héros doubrovskien et sa compagne du moment rappelle les hypothèses de Doubrovsky dans Corneille ou la dialectique du héros (1963), inspirées de la dialectique hégélienne du Maître et de l’Esclave. Cette thèse s’attache donc à analyser la relation dialectique auteur-lectrice telle que mise en scène et approfondie dans l’ensemble de l’édifice autofictionnel. Après présentation et étude des mécanismes dont se sert l’auteur pour construire son Lecteur Modèle (Première partie), les trois autres sections principales de la thèse sont consacrées à l’analyse de Fils et Un amour de soi (1977 et 1982 ; Deuxième partie) ; du Livre brisé et de l’Après-vivre (1989 et 1994 ; Troisième partie) ; et enfin de Laissé pour conte (1999 ; Quatrième partie). Il s’agira enfin de montrer la portée non seulement littéraire, mais également sociale (la réflexion s’élargit à chaque épisode pour aborder les questions de la réception contemporaine de l’œuvre littéraire) et historique (le motif Maître-Esclave s’inscrit dans l’Histoire de l’Europe du XXe siècle, plus précisément la Seconde Guerre mondiale et la Shoah) du thème dialectique doubrovskien.

Most panel unit root tests are designed to test the joint null hypothesis of a unit root for each individual series in a panel. After a rejection, it will often be of interest to identify which series can be deemed to be stationary and which series can be deemed nonstationary. Researchers will sometimes carry out this classification on the basis of n individual (univariate) unit root tests based on some ad hoc significance level. In this paper, we demonstrate how to use the false discovery rate (FDR) in evaluating I(1)=I(0) classifications based on individual unit root tests when the size of the cross section (n) and time series (T) dimensions are large. We report results from a simulation experiment and illustrate the methods on two data sets.

Dans un bassin versant, la connectivité hydrologique constitue un état hydrologique qui lie le versant à la zone riveraine. Ses impacts sur la production du débit et le transfert des éléments dissous vers le cours d’eau sont présumés substantiels. L’étude vise à 1) détecter les hydrotopes et les connexions hydrologiques à l’aide d’un réseau de puits qui permet la mesure des fluctuations de la nappe phréatique (NP); 2) identifier la variabilité spatio-temporelle et la signature géochimique des sources potentielles en eau à l’aide des éléments majeurs et traces et 3) examiner la contribution spatio-temporelle respective des sources en eau du bassin lors d’un événement de précipitation. L’étude s’effectue dans un bassin versant forestier du Bouclier canadien (l’Hermine). Nous démontrons l’existence de quatre hydrotopes représentant un gradient de convergence de l’eau, soulignant la diversité de comportement de NP. Les connexions hydrologiques se caractérisent par des coefficients de Spearman élevés des relations entre la profondeur de la NP et le débit, dans leur partie en aval, et s’enclenchent par le fill and spill. Le comportement de NP est influencé par la distance aux limites du bassin, l’horizonation du sol et la topographie souterraine. En somme, trois sources en eau se connectent à partir du versant vers la zone riveraine durant l’événement pluvial de manière chronologique: 1) les horizons B et la NP de l’ensemble du bassin (Sr); 2) les horizons LFH des zones de convergence (Ba et Zn) et 3) une dépression de sol humide sur le versant nord (Co et Mn).

The present study deals with a general introduction which outlines the objective of the study providing an exhaustive review of works on crabs with particular reference to deep-sea forms. In the first section, Taxonomy and Geographical disribution of the crab are dealt with. The species is described in detail based on several male and female specimens obtained from the pelagic and bottom collections, and its identity in Indian waters is established. It is also distinguished from a closely allied species so far not reported from Indian waters. The second section comprises the biology of the species and it is dealt with under four subheading, namely Habit and Habitats, Reproduction, Food and feeding and Proximate composition. The different habitats occupied by juveniles, subadults and adults of the species have been described and discussed in the light of available information on differential distribution of other related species. The reproductive biology is described in various details touching on gross anatomy and histology of the reproductive systems, spermatogenesis, oogenesis, size at maturity, ovarian maturation process, fecundity, egg carriage and breeding. The food and feeding habits of the species have been studied with reference to the different life stages such as juveniles, subadults and adults during the different phases of life based on stomach content analysis. The percentage of meat recovery and protein, carbohydrate and lipid content of meat have been described in the section dealing with proximate composition. In section three the distribution and abundance of the crab for the entire Indian EEZ and some contiguous ares have been described and illustrated in detail separately for pelagic and benthic realms. The size frequency disrtibution, sex ratios, length weight relationship and relative abundance of breeding population in the experimental catches have been dealt with in detail and discussed.

Optical properties of free and substituted porphyrins (PP) doped borate glass matrix are reported for the first time. Absorption spectral measurements of H2TPP, CdTPP, MgTPP and ZnTPP doped borate glass matrix have been made in the 200–1100 nm region and the spectra obtained are analyzed to obtain the optical bandgap (Eg) and other important spectral parameters viz. oscillator strength (f), molar extinction coefficient (ε), electric dipole strength (q2), absorption cross-section (σa) and molecular concentration (N). Intense fluorescence was observed in the region 668–685 nm for CdTPP, ZnTPP and MgTPP doped matrices, whereas no such fluorescence was observed in H2TPP doped matrix. Fluorescence intensity was observed to be almost similar in all the metallated porphyrine matrices. Fluorescence bandwidth (Δλ), decay time (τ), stimulated emission cross-section (σ) and optical gain (G) of the principal fluorescence transitions corresponding to the Q-band excitation were also evaluated and discussed.

El Lago Chad ha sido durante varias décadas, una fuente de supervivencia económica para millones de personas que habitan en cuatro Estados a saber; Nigeria, Níger, Chad y Camerún. No obstante, el cambio climático, el aumento acelerado de la población, la explotación insostenible y la mala regulación de los Estados ribereños han sido los principales factores que han dado lugar, en la última década, a la dramática reducción del nivel del Lago Chad. Teniendo en cuenta que los Estados aledaños al Lago, se encuentran inmersos en una Interdependencia Compleja, este nuevo contexto, ha tenido un impacto directo en la región, debido a que ha agravado otras variables económicas, sociales, ambientales y políticas, dejando un ambiente de inseguridad regional. De esta manera, la reducción de la Cuenca del Lago Chad representa una amenaza compartida que vincula estrechamente a Nigeria, Níger, Chad y Camerún, lo que permite vislumbrar la existencia de un Subcomplejo de Seguridad Regional.

As transformações na dinâmica demográfica ocorrida nas últimas décadas nos espaços urbanos passam, em grande medida, pela reconfiguração territorial, econômica e social das áreas metropolitanas, na qual os movimentos das pessoas exercem influência fundamental. Para este trabalho, propomos uma abordagem sobre o movimento migratório intra-metropolitano em 14 áreas metropolitanas brasileiras, quais sejam: Belém, Belo Horizonte, Brasília, Campinas, Curitiba, Florianópolis, Fortaleza, Goiânia, Porto Alegre, Recife, Rio de Janeiro, Salvador, São Paulo e Vitória; questionamos se este fenômeno estaria alterando a histórica “pressão pelas áreas centrais metropolitanas” ou se essa população está mudando de residência, mas continua trabalhando no núcleo. Pensando sobre os movimentos da população ocupada nas regiões metropolitanas, buscamos ainda considerar os tipos de movimentos realizados (núcleo-periferia; periferia-núcleo e periferia-periferia) com uma caracterização desta população. Portanto, nossa reflexão está relacionada às diferentes lógicas que operam sobre o lugar de moradia das pessoas e os lugares de outros fazeres que determinam a vida urbana, especialmente o lugar de trabalho. A localização dos postos de trabalho em áreas mais “centrais” e a quantidade considerável de pessoas que se deslocam para estes municípios também são fenômenos expressivos ainda. Será que os movimentos cotidianos podem se apresentar como uma alternativa para a residência em outras áreas da metrópole e o trabalho nas áreas centrais? Nossa proposta é a de que esses processos precisam ser analisados cada vez mais em conjunto com a migração intra-metropolitana.

A fundamental principle of democracy is citizenship freedom. We suggest that a fair electoral contest is possible if a relationship between free will, electoral preferences and respect to the public institutions (constitutionalism) (section 1) exists. We focus on three illiberal practices that perturb the voter's decision: political clientelism and political markets (sections 2 to 4), media influence (which feeds on the voter's limited rationality and limited information) (section 5), and the suppression of opposition options (section 6). Later (section 8), we provide a brief balance and, additionally, we show how in Colombia the political system has missed opportunities to expand the voters' freedom. Our interpretation of the electoral process in Colombia is an appeal, supported on theoretical arguments and empirical evidence, to doubt about the voters' freedom. Also we make a call for more etudies.

In the midst of health care reform, Colombia has succeeded in increasing health insurance coverage and the quality of health care. In spite of this, efficiency continues to be a matter of concern, and small-area variations in health care are one of the plausible causes of such inefficiencies. In order to understand this issue, we use individual data of all births from a Contributory-Regimen insurer in Colombia. We perform two different specifications of a multilevel logistic regression model. Our results reveal that hospitals account for 20% of variation on the probability of performing cesarean sections. Geographic area only explains 1/3 of the variance attributable to the hospital. Furthermore, some variables from both demand and supply sides are found to be also relevant on the probability of undergoing cesarean sections. This paper contributes to previous research by using a hierarchical model and by defining hospitals as cluster. Moreover, we also include clinical and supply induced demand variables.

Les anàlisis realitzades en cent deu poblacions de truita comuna (Salmo trutta) que abarquen el seu rang natural de distribució indiquen que el patró filogenètic es relaciona amb les tres grans vessants on es troba distribuïda l'espècie: ponto-càspia, atlàntica i mediterrània. Aquesta diferenciació estaria associada a l'aïllament de les vessants durant el Quaternari. L'origen de l'espècie es relaciona amb la vessant ponto-càspia, d'acord amb els models biogeogràfics que postulen l'origen asiàtic de la ictiofauna europea. S'ha detectat també un segon nivell de divergència dins de cada vessant que dóna com a resultat l'existència de sis llinatges evolutius: Atlàntic i Duero a la vessant atlàntica, els llinatges Adriàtic, Mediterrani i Marmoratus als rius mediterranis, i el llinatge Danubi a la zona ponto-càspia. Les glaciacions del Pleistocè han modificat profundament el rang de distribució de la truita comuna, especialment a la vessant atlàntica, on s'han proposat quatre grans refugis glacials: a l'est de la capa de gel, a Europa central, a l'entorn del canal de la Mànega i a l'entorn del golf de Biscaia; tot i que només els tres primers haurien participat en la recolonització del nord d'Europa al final de l'última glaciació. El quart refugi, que inclou el sud de França i el Cantàbric hauria estat l'origen de l'expansió cap al sud durant el Pleistocè Superior d'un grup de poblacions distribuïdes actualment a la vessant atlàntica ibèrica, i també hauria servit de base per a l'expansió cap al nord d'altres grups de truita durant interglacials anteriors. A la vessant atlàntica de la peninsula Ibèrica, l'estructura poblacional es troba associada a la xarxa hidrogràfica i es determinen fins a cinc unitats poblacionals: les truites dels rius Cantàbrics, les del Miño, les del Duero, les del Tajo i les del Guadalquivir. Les poblacions del Guadalquivir pertanyerien a un grup d'influència mediterrània. Els marcadors d'al·lozims i de DNA mitocondrial es troben fortament correlacionats en aquesta vessant, on apunten cap als mateixos grups de poblacions. Per contra, els rius de la vessant mediterrània haurien estat colonitzats pels llinatges Adriàtic i Mediterrani i s'hauria produït una intensa intergradació secundària entre aquests llinatges durant els períodes glacials a partir de l'expansió de les poblacions retingudes a les capçaleres durant els interglacials. Els grups de hibridació, l'aïllament i la deriva en el període interglacial fa que els grups de poblacions identificats pels marcadors d'al·lozims i de DNA mitocondrial no coincideixin.

This contribution addresses the implications of the boundary demarcation on basin of Orinoco and Amazon, during the second half of the 18th Century, beginning with the study of the expedition of the boundary between Spain and Portugal. This enterprise ended up in a surprise of games of omission, unfortunate and personal confrontations. The undesired task for the Spanish Guayana, however, marked a radically change in the geostrategic valuing and paved way to a latter colonial modernity thanks to the initiative of its commissioners. In this way, an important part of the territorial integrity was preserved against the geographical desires of lustanas and stopped the trafficking of indigenous salves towards the Amazon region.
