Los Mapas de riesgo de inundaciones: representación de la vulnerabilidad y aportación de las innovaciones tecnológicas

Los mapas de riesgo de inundaciones deberían mostrar las inundaciones en relación con los impactos potenciales que éstas pueden llegar a producir en personas, bienes y actividades. Por ello, es preciso añadir el concepto de vulnerabilidad al mero estudio del fenómeno físico. Así pues, los mapas de riesgo de daños por inundación son los verdaderos mapas de riesgo, ya que se elaboran, por una parte, a partir de cartografía que localiza y caracteriza el fenómeno físico de las inundaciones, y, por la otra, a partir de cartografía que localiza y caracteriza los elementos expuestos. El uso de las llamadas «nuevas tecnologías», como los SIG, la percepción remota, los sensores hidrológicos o Internet, representa un potencial de gran valor para el desarrollo de los mapas de riesgo de inundaciones, que es, hoy por hoy, un campo abierto a la investigación

Le regard d'un psychiatre sur les écrits de la folie : la carrière de Hans Steck à l'Asile psychiatrique de Cery (1920-1960)

Quelles représentations de la schizophrénie les psychiatres vont-ils construire à travers l'étude des écrits asilaires des patients et des scientifiques dans la première moitié du XXème siècle? Le psychiatre helvétique Hans Steck (1891-1980), qui a travaillé à l'Asile psychiatrique de Cery de 1920 à 1960 et qui s'est fait connaître du public grâce à l'oeuvre d'Aloïse Corbaz, reconnue comme auteure d'art brut par Jean Dubuffet en 1945, constitue le fil rouge de la thèse. Dans le contexte des mouvements tels que Γ "art psychopathologique" et Γ "art brut", Steck étudie les théories de "la mentalité primitive et les peintures magiques des schizophrènes". En 1927, il se tourne vers les théories évolutionnistes de la régression et les premières études de Lévy-Bruhl pour avancer l'idée qu'il existe un "parallélisme schizo-primitif'. Puis il développe des explications de la pensée délirante, à partir des théories exposées lors du Premier Congrès International de Psychiatrie en 1950. Enfin, adoptant la perspective phénoménologique, il explique que "la fonction de l'art et la fonction du délire visent à reconstituer un monde viable pour le malade". En ce sens, l'expression artistique, bien que n'entrant pas dans le champ de la psychothérapie, fournit des indicateurs de l'état psychique du malade en même temps qu'elle contribue à son bien-être. Sont abordés les problèmes concernant la reconnaissance de Γ "auteur" interné, dont les oeuvres appartiennent soit aux archives médicales, soit au musée. La pérennité des critères qui définissent les oeuvres d'"art psychopathologique" ou d'"art brut" est également mise en question. Enfin, le rôle essentiel de l'écriture à l'hôpital, tant pour les patients que pour les soignants, fait l'objet de nombreux développements. - What representations of schizophrenia have psychiatrists been constructing when studying writings by patients and scientists in mental asylums in the first half of the 20th century? The Swiss psychiatrist Hans Steck (1891-1980) is the protagonist of this dissertation. From 1920 to 1960, he has been working at the "Asile psychiatrique de Cery" near Lausanne. Steck is known thanks to the paintings of Aloïse Corbaz, an artist recognized by Jean Dubuffet as belonging to the "art brut" movement in 1945. In the context of movements like "art psychopathologique" and "art brut," Steck studies theories of "primitive character and magic paintings of schizophrenics." In 1927, Steck engages with theories of regression and Lévy-Bruhl's early studies in order to push the idea of a "parallelism schizo-primitif." On the occasion of the First International Congress of psychiatry held in Paris in 1950, Steck develops explanations for the "pensée délirante." Finally, turning to a phenomenological point of view, he explains, "the function of art and the function of the delusion help the patient to reconstruct a viable environment for the sick person." In this way, artistic expression is not thought of as a psychotherapeutical means, but provides insight into the state of mind of a mentally sick person at the same time as contributing to his well-being. The dissertation discusses whether the "author's" work belongs in medical archives or museums. The continuity of "psychopathological art" and "art brut" criteria will be discussed. Finally, the essential role that writing played in the hospital for the patients as well as for the medical staff is presented.

New perspective on the study of the authority relationship: Integrating individual and societal level research.

The concept of authority crosses many social sciences, but there is a lack of common taxonomy and definitions on this topic. The aims of this review are: (1) to define the basic characteristics of the authority relationship, reaching a definition suitable for the different domains of social psychology and social sciences; (2) to bridge the gap between individual and societal levels of explanation concerning the authority relationship, by proposing an interpretation within the framework of social representations. The authority relationship can be conceived as a negotiation of meanings and it is closely linked to shared value orientation and the attribution of meanings negotiated within a society. We assume that the authority relationship is socially constructed and represents both a shared representation of society and a normative principle of social life. A multidisciplinary approach is adopted, crossing definitions and studies provided in sociology, political science, law and social psychology.

Perceptual and semantic contributions to repetition priming of environmental sounds.

Repetition of environmental sounds, like their visual counterparts, can facilitate behavior and modulate neural responses, exemplifying plasticity in how auditory objects are represented or accessed. It remains controversial whether such repetition priming/suppression involves solely plasticity based on acoustic features and/or also access to semantic features. To evaluate contributions of physical and semantic features in eliciting repetition-induced plasticity, the present functional magnetic resonance imaging (fMRI) study repeated either identical or different exemplars of the initially presented object; reasoning that identical exemplars share both physical and semantic features, whereas different exemplars share only semantic features. Participants performed a living/man-made categorization task while being scanned at 3T. Repeated stimuli of both types significantly facilitated reaction times versus initial presentations, demonstrating perceptual and semantic repetition priming. There was also repetition suppression of fMRI activity within overlapping temporal, premotor, and prefrontal regions of the auditory "what" pathway. Importantly, the magnitude of suppression effects was equivalent for both physically identical and semantically related exemplars. That the degree of repetition suppression was irrespective of whether or not both perceptual and semantic information was repeated is suggestive of a degree of acoustically independent semantic analysis in how object representations are maintained and retrieved.

Ler melhor através dos temas e mitos na literatura cabo-verdiana : uma análise comparativista

Esta dissertação teve como ponto de partida a pergunta “Como se comportaram alguns temas e mitos ao longo da história da literatura de Cabo Verde? Que caminho percorreram?” Para tentar dar-lhe resposta recorremos à metodologia comparativista, com o objetivo de analisar as evoluções e possíveis mudanças ocorridas ao longo dos tempos, a partir do cruzamento transversal entre temas e mitos em épocas diferentes. Foi assim necessário abordar a literatura cabo-verdiana, na sua relação profunda com a história do país, considerando os seus três grandes momentos: um tempo “ indefinido” que vai até 1936, um segundo que vai de 1936 até 1975 e, por último, o que vai desde essa data até à atualidade. Ao longo dessa análise, e a partir de um corpus textual necessariamente circunscrito, fomos detetando as variantes, as diferentes atualizações ocorridas nesta literatura, geralmente provocadas por fatores de ordem geográfica, pela evolução histórico-social, por fatores ideológicos que se prenderam sobretudo com a falta de liberdade vivida até 1975. Esta abordagem comparativista, a análise intertextual que lhe é inerente, proporcionou, não uma simples comparação, mas o desvendar de relações múltiplas existentes entre as obras, o corpus literário escolhido, e os tempos que lhes deram origem, permitindo assim conhecer as partes e, consequentemente o todo através do “desocultamento do oculto”. Constatou-se uma migração dos temas e dos mitos entre as literaturas dos três momentos. Em certos casos, alguns elementos permaneceram, mas com novas representações, noutros assumem significados radicalmente diferentes dados os atuais contextos da sua recepção. Relativamente aos mitos, observou-se a sua crescente dessacralização, em sintonia com o progresso que o país foi conhecendo após a independência nacional. A leitura que fomos fazendo conduziu-nos deste modo a uma viagem ao passado do país. Esta leitura transversal, alicerçada na história, dando conta das transformações ocorridas ao longo dos tempos, mostrou-nos ainda de forma cabal a necessidade de se introduzirem mudanças no ensino da literatura nas escolas cabo-verdianas. Uma mudança que deverá passar por uma abordagem comparativista, que privilegia as relações entre textos de diferentes épocas, a sua perspetivação interdisciplinar com outras formas de expressão, capaz de transformar o aluno-mero-receptor num leitor ativo, implicado numa realidade que lhe diz respeito.

Male beach workers and western female tourists : livelihood strategies in Kenya's south coast region

Recent years have seen an emerging knowledge base and increasing public interest and awareness of sexual-economic relationships between local men and Western women, in different touristic regions around the world. However, to date, Western perspectives on the phenomenon make up the bulk of the existent literature. Questioning the dominant discourse of 'romance tourism' and representations of male participants as 'victims-opportunists', this dissertation explores male beach workers' experiences with, and perspectives on sexual-economic relationships between Kenyan men and visiting Western women in Kenya's South Coast region. The men were not considered in isolation; their experiences and perspectives are situated in relation to their family ties, social networks and the political economy of beach tourism. The study shows that locally these relationships are clearly understood as livelihood strategies for the visited. Men seek to establish long-term intimate relationships with female tourists as a means to accessing life's basic necessities for themselves and for their families and overall to improve their standards of living. It is argued that these relationships are a response to the poverty and inequalities generated by socio-economic changes over time. They are also a response to local gender role prescriptions that hinge male social value on men's capacity to marry, procreate and provide intergenerational social and economic support. The men's parallel quest for non-sexual economically motivated friendships with visiting foreign tourists termed "family friends" is a salient finding, that serves to reinforce the finding that the sexual- economic relationships are above all livelihood strategies. Résumé Ces dernières années ont vu l'émergence d'une base de connaissance, ainsi que d'un intérêt et d'une prise de conscience accrue du public, à l'égard des relations économico-sexuelles entre hommes locaux et femmes occidentales, dans différentes régions touristiques du monde. Cependant, à ce jour, des perspectives occidentales sur ce phénomène constituent l'essentiel de la littérature existante. En remettant en question le discours dominant du «romance tourism» (tourisme sentimental) et les représentations qui conçoivent les hommes participants comme étant 'victimes-opportunistes', cette thèse explore les expériences, et les visions qu'ont les travailleurs de plage sur les relations économico-sexuelles entre hommes Kenyans et femmes Occidentales dans la région de la côte sud du Kenya. Les hommes n'ont pas été considérés de manière isolée; leurs expériences et leurs perspectives sont situées par rapport à leur liens familiaux, leur réseaux sociaux et aussi par rapport à l'économie politique du tourisme balnéaire. L'étude montre que sur place ces relations sont clairement conçues comme des stratégies de survie pour les participants hôtes. Les hommes cherchent à établir des relations de long durée avec des femmes touristes comme moyen d'accéder à des biens et des services qui constituent des nécessités de bases, pour eux et pour leur familles et globalement pour relever leur niveau de vie! L'étude fait valoir que ces relations sont une réponse à la pauvreté et aux inégalités sociales crées par des dynamiques socio-économiques au fil du temps. Elles sont aussi une réponse au prescriptions sociales locales par lesquelles la valeur sociale masculine est définie à travers la capacité des hommes à se marier, à procréer et d'assurer un soutien intergénérationnel social et économique. La quête, en parallèle, de relations d'amitiés non-sexuelles à motivation économique, dénommé « family friends », par des hommes, est un résultat saillant de cette étude qui vient renforcer l'observation que les relations économico-sexuelles relèvent avant tout des stratégies de survie.

Between Equity and Differentiation: An Analytical Schema of the Social Function of Education

The educational sphere has an internal function relatively agreed by social scientists. Nonetheless, the contribution that educational systems provide to the society (i.e., their social function) does not have the same degree of consensus. Taking into consideration such theoretical precedent, the current article raises an analytical schema to grasp the social function of education considering a sociological perspective. Starting from the assumption that there is an intrinsic relationship between the internal and social functions of social systems, we suggest there are particular stratification determinants modifying the internal pedagogical function of education, which impact on its social function by creating simultaneous conditions of equity and differentiation. Throughout the paper this social function is considered a paradoxical mechanism. We highlight how this paradoxical dynamic is deployed in different structural levels of the educational sphere. Additionally, we discuss eventual consequences of this paradoxical social function for the inclusion possibilities that educational systems offer to individuals.

Like Man, Like Woman: Roman Women, Gender Qualities and Conjugal Relationships at the Turn of the First Century

Modern scholarship often discusses Roman women in terms of their difference from their male counterparts, frequently defining them as 'other'. This book shows how Roman male writers at the turn of the first century actually described women as not so different from men: the same qualities and abilities pertaining to the domains of parenthood, intellect and morals are ascribed by writers to women as well as to men. There are two voices, however: a traditional, ideal voice and an individual, realistic voice. This creates a duality of representations of women, which recurs across literary genres and reflects a duality of mentality. How can we interpret the paradoxical information about Roman women given by the male-authored texts? How does this duality of mentality inform us about gender roles and gender hierarchy? This work analyses well-known, as well as overlooked, passages from the writings of Pliny the Younger, Tacitus, Suetonius, Quintilian, Statius, Martial and Juvenal and sheds new light on Roman views of women and their abilities, on the notions of private and public and on conjugal relationships. In the process, the famous sixth satire of Juvenal is revisited and its topic reassessed, providing further insights into the complex issues of gender roles, marriage and emotions. By contrasting representations of women across a broad spectrum of literary genres, this book provides consistent findings that have wide significance for the study of Latin literature and the social history of the late first and early second centuries.

Que promettent les styles d'interactions? Une approche sociologique de l'intimité conjugale

This article intends to grasp the stabilization process, deterioration or improvement of the conjugal intimacy over five years, based on a representative sample of couples living in Switzerland. The dynamics develop in different ways depending on the degree of autonomy of the partners, the gendering of household tasks, conjugal openess and the coping strategies of the couples.

Discovery of the faithfulness gene: a model of transmission and transformation of scientific information.

The purpose of this paper is to study the diffusion and transformation of scientific information in everyday discussions. Based on rumour models and social representations theory, the impact of interpersonal communication and pre-existing beliefs on transmission of the content of a scientific discovery was analysed. In three experiments, a communication chain was simulated to investigate how laypeople make sense of a genetic discovery first published in a scientific outlet, then reported in a mainstream newspaper and finally discussed in groups. Study 1 (N=40) demonstrated a transformation of information when the scientific discovery moved along the communication chain. During successive narratives, scientific expert terminology disappeared while scientific information associated with lay terminology persisted. Moreover, the idea of a discovery of a faithfulness gene emerged. Study 2 (N=70) revealed that transmission of the scientific message varied as a function of attitudes towards genetic explanations of behaviour (pro-genetics vs. anti-genetics). Pro-genetics employed more scientific terminology than anti-genetics. Study 3 (N=75) showed that endorsement of genetic explanations was related to descriptive accounts of the scientific information, whereas rejection of genetic explanations was related to evaluative accounts of the information.

Veus ignorades: representacions socials, subjectivitat i resiliència en persones grans amb pèrdua d’autonomia funcional

Els processos per a l’aprovació i la implementació de la Llei per a l’Autonomia personal i l’Atenció a les Persones en situació de Dependència (LAPAD) han donat lloc a un intens debat polític i social que, coincidint també amb les millores en la provisió de serveis i els avenços mèdics, ha contribuït a un procés de classificació i d’etiquetatge basats en els dèficits de les persones que es troben en aquestes circumstàncies. Aquesta visió anul·la el subjecte i la seva experiència singular i condiciona l’abordatge dels models d’atenció i de cura. L’estudi pretén fer una aproximació a les persones grans amb pèrdua d’autonomia funcional, fent emergir les seves veus, que expressen com perceben, interpreten, afronten i es reajusten a la nova situació. Partint d’un enfocament constructivista, basat en la subjectivitat, es fa un recorregut sobre els models de la discapacitat que han reeixit en l’activitat científica dels darrers anys, els mecanismes de regulació de les pèrdues que defensen les teories del cicle vital i les aportacions que s’han fet sobre el model de la resiliència aplicat a les persones que envelleixen. El resultats de l’estudi mostren com les representacions i els significats que les persones grans atribueixen a la seva experiència s’inscriuen en les seves trajectòries vitals, donant un sentit únic i singular a la forma de viure i de respondre a la pèrdua d’autonomia funcional i les seves conseqüències. Aquelles que expressen una vivència d’integritat respecte de la vida viscuda, amb predomini d’afectes positius envers un mateix i els altres, que conserven l’esperança i el desig de continuar vivint, s’ajusten a les pèrdues de manera més satisfactòria que aquelles que expressen desconfiança i una certa amargor respecte de la pròpia vida. D’això se’n deriva que els espais d’escolta i d’acompanyament poden ser un recurs vàlid i necessari en el qual, a través de la paraula i el testimoni narrat, el subjecte pugui repensar i resignificar les seves experiències.

Single Subject Finger Somatotopy Mapping at 7T.

Introduction: The primary somatosensory cortex (SI) contains Brodmann areas (BA) 1, 2, 3a, and 3b. Research in non-human primates showed that BAs 3b, 1, and 2 each contain one full representation of the hand with separate representations for each finger. This research also showed that the finger representation in BA3b has larger and clearer finger somatotopy than BA1 and 2. Although several efforts to map finger somatotopy in SI by fMRI have been made at 1.5 and 3T these studies have yielded variable results and were not able to detect single subject finger somatotopy, probably due to the limited spatial extent of the cortical areas representing a digit (close to the resolution in most fMRI experiments), complications due to acquisition of consistent maps for individual subjects (Schweizer et al 2008), or inter-individual variability in sulcal anatomy impeding group studies. Here, we used 7T fMRI to investigate finger somatotopy in SI, some of its functional characteristics, and its reproducibility. Methods: Eight right-handed male subjects were scanned on a 7T scanner (Siemens Medical, Germany) with an 8-channel Tx/Rx rf-coil (Rapid Biomedical, Germany). 1.3x1.3x1.3mm3 resolution fMRI data were acquired using a sinusoidal readout EPI sequence (Speck et al, 2008) and FOV=210mm, TE/TR=27ms/2.5s, GRAPPA=2. Each volume contained 28 transverse slices covering SI. A single EPI volume with 64 slices was acquired to aid coregistration. 1x1x1mm3 anatomical data were acquire using the MP2RAGE sequence (Marques et al, 2009; TE/TR/TI1,2/TRmprage=2.63ms/7.2ms/0.9,3.2s/5s). Subjects were positioned supine in the scanner with their right arm comfortably against the magnet bore. An experimenter was positioned at the entrance of the bore where he could easily reach and stroke successively the two distal phalanxes of each digit. The order of stroked digit was D1 (thumb)-D3-D5-D2-D4, with 20s ON, 10s OFF alternated. This sequence was repeated four times per run and two functional runs were acquired per subject. Realignment, smoothing (FWHM 2 mm), coregistration of the anatomical to the fMRI data and calculation of t-statistics were done using SPM8. An SI mask was obtained via an F-contrast (p<0.001) over all digits. Within the mask, voxels were labeled with the number of the digit demonstrating the highest t-value for that particular voxel. Results: For all subjects, areas corresponding to the five digits were identified in contralateral SI. BA3b showed the most consistent somatotopic finger representation (see an example in Fig.1). The five digits were localized in a consecutive order in the cortex, with D1 most anterior, inferior and distal and D5, most posterior, superior and medial (mean distance between centres of mass of digit representations ±stderr: 4.2±0.7mm; see Fig. 2). The analysis of average beta values within each finger representation region revealed the specificity of the somatotopic region to the tactile input for each tested finger (except digit 4 and 5). Five of these subjects also presented an orderly and consecutive representation of the five digits in BA1 and 2. Conclusions: Our data reveal that the increased BOLD sensitivity at 7T and the high spatial resolution used in this study allow consistent somatotopic mapping using human touch as a stimulus and that human SI contains at least three separate regions that contain five separate representations of all single contralateral fingers. Moreover, adjacent fingers were represented at adjacent cortical regions across the three SI regions. The spatial organization of SI as reflected in individual subject topography corresponds well with previous electrophysiological data in non-human primates. The small distance between digit representations highlights the need for the high spatial resolution available at 7T.

IDENTITÉ, PROJET, CHANGEMENT : DES REPRÉSENTATIONS SOCIALES AUX LEVIERS DE L'ACTION PUBLIQUE. POUR UN MODE DE GOUVERNANCE AXÉ SUR LE DÉVELOPPEMENT TERRITORIAL. ETUDE DE CAS : CANTON DU JURA (SUISSE)

Thirty years after the Canton of Jura entered sovereignty, it has to be admited that the creation of the newly canton did't fullfill the hopes of economic and demografic growth that many could have expected from political independance. Through a plurality of complementary approaches, the research suggest a closer look at, on one hand, the position of the Canton in its territorial context as well as its structure and dynamics and on the other hand, the representations of the territory and its evolution by the social actors. This in order to formulate a set of social demands (of debate, of openness and of overcoming cleavages) which augurs for a new territoriality regime and testify of a requirement of reflexivity toward the state institutions and actions. The analysis allowed to set in evidence the central role of the couple identity-project in the dynamics of change, and to identifiy three main periods in the recent past of the Canton: a period of territorialization, during which grew a strong collective identity, coupled with a major project of society (the creation of the canton of Jura); then followed a period of deterritorialization, with the fragmentation of the collective identity and the lack of a project of society. Then, the third period, with a paradoxical event, the failure in public vote of the the project Jura open Land (Jura Pays ouvert), which was meant to give a second wind to the Canton. We consider this turning point as the start of a new period (of reterritorialization), with an issue linked with the outlines of a renewed "jurassian" identity and the elaboration of a shared territory project.Trente ans après l'entrée en souveraineté, force est de constater que la création du canton du Jura n'a pas permis de répondre aux espérances de développement économique et démographique que l'indépendance politique devait entraîner dans son sillage. Cette recherche se propose, à travers une pluralité d'approches complémentaires, d'examiner d'une part la position du Canton dans son contexte territorial ainsi que sa structure et sa dynamique; d'autre part, les représentations que se font les acteurs du territoire et de son évolution, pour déboucher sur une série de demandes sociales (de débat, d'ouverture et de dépassement des clivages) qui augurent de la transition vers un nouveau régime de territorialité et témoignent d'une exigence de réflexivité envers les institutions et les actions de l'Etat. L'analyse a permis de mettre en évidence le rôle central du couple identité-projet dans la dynamique de changement et d'identifier trois temps forts dans l'évolution récente du Canton, une phase de territorialisation au cours de laquelle s'est constituée une identité forte doublée d'un projet de société majeur, suivie d'une phase de déterritorialisation avec une fragmentation de l'identité collective et l'absence de projet mobilisateur. Enfin, un moment paradoxal, l'échec du projet Jura Pays ouvert, censé redonner un second souffle au Canton, qui amorce une nouvelle étape (de reterritorialisation) avec un questionnement lié aux contours d'une identité jurassienne renouvelée et à l'élaboration d'un projet de territoire partagé.Les ressorts de la production du territoire et de son développement sont analysés à travers le rôle des représentations sociales dans la constitution identitaire et le projet territorial, à l'exemple du canton du Jura. La mise en évidence du rôle central du couple identité-projet dans la dynamique de changement a permis d'identifier trois temps forts dans l'évolution récente du Canton. Une première phase (la création du canton du Jura), au cours de laquelle s'est constituée une identité forte doublée d'un projet de société majeur, suivie d'une phase au cours de laquelle l'identité collective s'est fragmentée en l'absence de projet mobilisateur (la phase de « gestion » de l'Etat). Puis un moment de rupture (l'échec du projet Jura Pays ouvert) et l'amorce d'une transition vers une nouvelle étape, avec un questionnement lié aux contours d'une identité jurassienne renouvelée, à l'élaboration d'un projet de territoire partagé, et à l'action des pouvoirs publics dans un contexte de repositionnement du Canton.
