Attachement à la mère et au père, intersubjectivité et utilisation d'informations publiques.

La théorie de l'attachement est une théorie dyadique, par essence. Même si le père peut être reconnu comme une réelle figure d'attachement, en ce sens qu'il est susceptible de procurer à l'enfant une expérience de sécurité, la théorie reste essentiellement dyadique. Redéfinir la théorie de l'attachement dans une perspective triadique n'est pas sans poser des difficultés théoriques. Ace propos, nous suggérons une perspective inspirée par un concept d'écologie comportementale, celui de l'utilisation adaptative par les organismes d'informations publiques fournies par inadvertance par d'autres organismes, concept que nous étendrons à cette fin aux expressions émotionnelles. Nous proposons alors l'idée que dans la triade, chaque partenaire utilise ce type d'informations, fournies à la fois par chacun des autres partenaires ainsi que par les interactions ellesmêmes entre ces partenaires. L'utilisation de ces informations aurait, dans cette perspective, une fonction adaptative pour le maintien de la triade comme une entité soudée par des échanges d'expériences émotionnelles. The theory of attachment is essentially a dyadic theory. Even though the father is recognised as a real figure of attachment in that he brings a feeling of security to the child, basically the theory remains dyadic. Redefining the theory of attachment in a triadic perspective is not without raising difficult theoretical problems. This leads us to suggest a perspective inspired by the concept of ecological behaviour : the adaptative use of public information acquired inadvertently through other organisms, a concept applied here to emotional expression. We propose that in the triad each partner uses this type of information brought by the other partner as well as those very interactions between both partners. The use of information to maintain the triad as an entity bound by exchanges of emotional experience would be an adaptative function.

Trade policy and regional inequalities

This paper aims to analyse the effects of trade policies in the pattern of regional inequalities within a country. Inspired firstly, by the debate concerning the role of protectionist policies in the settlement of a pattern of striking regional inequalities in the Spanish industrialisation process and secondly, by current evidence of an increase in these inequalities following the entry of Spain in the EU (1986), we set a model that shows that trade liberalisation increases regional inequalities.

Gériatrie aiguë: un modèle d'unité intégree de soins aux seniors [How to prevent functional decline: an acute care unit model for the elderly].

Hospitalization in older patients is frequently associated with functional decline. Hospital factors and inadapted process of care are factors leading to this decline. Acute care units specifically developed for older patients can prevent functional decline. These units usually include a comprehensive geriatric evaluation, an interdisciplinary meeting, protocols for the treatment of geriatric syndromes and specific teaching for the care team. Globally, patients' cares are organized to preserve and improve functional performances. This article presents a pilot unit inspired by this model.

The mechanism of Hsp70 chaperones: (entropic) pulling the models together.

Hsp70s are conserved molecular chaperones that can prevent protein aggregation, actively unfold, solubilize aggregates, pull translocating proteins across membranes and remodel native proteins complexes. Disparate mechanisms have been proposed for the various modes of Hsp70 action: passive prevention of aggregation by kinetic partitioning, peptide-bond isomerase, Brownian ratcheting or active power-stroke pulling. Recently, we put forward a unifying mechanism named 'entropic pulling', which proposed that Hsp70 uses the energy of ATP hydrolysis to recruit a force of entropic origin to locally unfold aggregates or pull proteins across membranes. The entropic pulling mechanism reproduces the expected phenomenology that inspired the other disparate mechanisms and is, moreover, simple.

Face à l'insoutenable. Vivre et se construire avec des souvenirs d'abus sexuels

L'objectif de cette recherche est d'explorer l'impact des abus sexuels tel que perçu par des personnes adultes ayant été victimes dans leur enfance. Une attention particulière est portée sur l'évolution de cette perception. A cette fin, deux groupes de personnes ont été sollicités : des patients suivis en thérapie de groupe dans un centre spécialisé et des personnes ayant terminé une thérapie centrée sur les abus sexuels depuis au moins cinq ans.Des entretiens semi-structurés ont été menés tous les six mois pendant deux ans avec six femmes en thérapie, ainsi qu'avec trois femmes et un homme ayant terminé leur travail thérapeutique à ce sujet.L'analyse qualitative, inspirée de l'IPA, a révélé huit thèmes. A la recherche de la normalité, Vie intime et sexualité, et Du secret à la reconnaissance sont trois des problématiques majeures présentées par les femmes aux premiers entretiens. L'analyse révèle l'évolution de ces thèmes au cours des deux ans et les « témoins de l'après-thérapie » donnent des pistes quant aux suites possibles. Les participants témoignent également de leurs diverses Démarches thérapeutiques. Question de survie est un thème faisant trait à la dissociation structurelle de la personnalité telle qu'elle apparaît dans le discours des participants et telle qu'ils la décrivent. De la réviviscence au souvenir, Attribution de sens et Vivre après amènent chacun des aspects spécifiques liés à la résilience et ultimement à l'épanouissement.Ces résultats font ressortir des thématiques qui se révèlent être particulièrement difficiles pour ces personnes ayant été abusées sexuellement dans leur enfance, tout en soulignant l'évolution possible au fil du temps et à l'aide des thérapies. Ils révèlent également les manières dont le traumatisme est peu à peu intégré par les participants dans leur histoire de vie.This study's aim is to explore how survivors perceive the impact on their adult life of child sexual abuse and how it changes over time. To this effect, two groups of people were solicited: patients involved in group therapy in a specialised treatment centre and people who had finished therapy focused on the trauma caused by the abuse at least five years prior to this study.Semi-structured interviews were conducted at 6-month intervals over two years with six women in therapy. Three women and one man who had finished therapy accepted to share their experience.Qualitative analysis inspired by IPA revealed eight themes. Searching for normality, Tuning feelings with sexual life, and From secrecy to acknowledgment are three of the main issues presented by the women at the initial interviews. The analysis reveals how these themes evolve over the two years, while the participants who have finished their therapy give insights of possible futures. Participants also reflected on their various Therapeutical experiences. A matter of survival relates to structural dissociation of the personality as it appears in the participants' discourse and as they describe it. Placing the memory in the past, Making meaning, and And life goes on each bring out specific aspects linked to resiliency and finally to thriving.These results highlight the issues that are particularly difficult in dealing with the aftermaths of child sexual abuse and underline their possible transformation with time and therapy. They also reveal the ways in which the trauma is gradually integrated by the participants into their life-history.

Coisotropic regularization of singular Lagrangians

We present an alternative approach to the usual treatments of singular Lagrangians. It is based on a Hamiltonian regularization scheme inspired on the coisotropic embedding of presymplectic systems. A Lagrangian regularization of a singular Lagrangian is a regular Lagrangian defined on an extended velocity phase space that reproduces the original theory when restricted to the initial configuration space. A Lagrangian regularization does not always exists, but a family of singular Lagrangians is studied for which such a regularization can be described explicitly. These regularizations turn out to be essentially unique and provide an alternative setting to quantize the corresponding physical systems. These ideas can be applied both in classical mechanics and field theories. Several examples are discussed in detail. 1995 American Institute of Physics.

C'est la plume qui fait le conte : "Die sechs Schwäne" des frères Grimm et "De vilde Svaner" de Hans Christian Andersen

Dans De vilde Svaner (Les cygnes sauvages), conte des Eventyr, fortalte for Børn (Contes, racontés aux enfants), H. C. Andersen raconte une histoire très proche de celle de Die sechs Schwäne (Les six cygnes), des Kinder- und Hausmärchen (Contes de l'enfance et du foyer) des Grimm. On peut fort justement se demander si l'auteur danois ne réécrit pas le Märchen de 1812 lorsqu'il publie son eventyr, en 1838. Mais l'étude de plusieurs récits d'enfants transformés en cygnes - de l'histoire du septième sage du Dolopathos de Jean de Haute-Seille, à la fin du xiie siècle, et Die sieben Schwäne, un Feen-Märchen de 1801, à De elleve Svaner de Winther, en 1823 - montre qu'Andersen réécrit vraisemblablement ce dernier texte danois et que le dialogue intertextuel avec les Grimm s'effectue sur un autre mode. L'auteur des Eventyr, fortalte for Børn se positionne par rapport aux Kinder- und Hausmärchen, développant ainsi une nouvelle conception du genre qui ressort de la comparaison des manières de raconter propres à chaque auteur, leur plume. It is the pen which makes the tale. the Grimm brothers' Die sechs Schwäne and Christian Andersen's De vilde Svaner In De vilde Svaner, a tale from Eventyr, fortale for Børn, H. C. Andersen tells a story that is very close to that of Die sechs Schwäne from the Grimms' Kinder- und Hausmärchen. One could legitimately wonder whether the Danish author was inspired by the 1812 Märchen when he published his own eventyr in 1838. The study of other narratives about children transformed into swans (including the story of the seventh wise man in Jean de Haute-Seille's Dolopathos at the end of the twelth century; Die sieben Schwäne, a Feen-Märchen from 1801; and Winther's 1823 De elleve Svaner) shows that Andersen rewrote this last Danish text and that the intertextual dialogue with the Grimms takes place at another level. Andersen distinguishes himself from the Grimms by developing a new conception of the genre, which becomes clear in his very different way of telling a tale.

Family impact in intellectual disability, severe mental health disorders and mental health disorders in ID. A comparison

Family impact (or family burden) is a concept born in the field of mental health that has successfully been exported to the ambit of intellectual disability (ID). However, differences in family impact associated with severe mental health disorders (schizophrenia), to ID or to mental health problems in ID should be expected. Seventy-two adults with intellectual disability clients of the Carmen Pardo-Valcarce Foundation's sheltered workshops and vocational employment programmes in Madrid (Spain), 203 adults diagnosed with schizophrenia from four Spanish Community Mental Health Services (Barcelona, Madrid, Granada and Navarra) and 90 adults with mental health problems in ID (MH-ID) from the Parc Sanitari Sant Joan de Déu Health Care Site in Sant Boi de Llobregat, Barcelona (Spain) were asked to participate in the present study along with their main caregivers. Family impact experienced by caregivers was assessed with the ECFOS-II/SOFBI-II scale (Entrevista de Carga Familiar Objetiva y Subjetiva/Objective and Subjective Family Burden Interview). In global terms, results showed that the higher family impact was found between caregivers to people with MH-ID. The interaction of both conditions (ID and mental health problems) results in a higher degree of burden on families than when both conditions are presented separately. There was also an impact in caregivers to people with schizophrenia, this impact being higher than the one detected in caregivers to people with intellectual disability. Needs of caregivers to people with disability should be addressed specifically in order to effectively support families.

La pertinence en science forensique. Une (en)quête épistémologique et empirique

A criminal investigation requires to search and to interpret vestiges of a criminal act that happened in a past time. The forensic investigator arises in this context as a critical reader of the investigation scene, in search of physical traces that should enable her to tell a story of the offence/crime which allegedly occurred. The challenge of any investigator is to detect and recognise relevant physical traces in order to provide forensic clues for investigation and intelligence purposes. Inspired by this obser- vation, the current research focuses on the following questions : What is a relevant physical trace? And, how does the forensic investigator know she is facing one ? The interest of such questions is to provide a definition of a dimension often used in forensic science but never studied in its implications and operations. This doctoral research investigates scientific paths that are not often explored in forensic science, by using semiotic and sociological tools combined with statistical data analysis. The results are shown following a semiotic path, strongly influenced by Peir- ce's studies, and a second track, called empirical, where investigations data were analysed and forensic investigators interviewed about their work practices in the field. By the semiotic track, a macroscopic view is given of a signification process running from the discove- red physical trace at the scene to what is evaluated as being relevant for the investigator. The physical trace is perceived in the form of several signs, whose meaning is culturally codified. The reasoning should consist of three main steps : 1- What kind of source does the discovered physical trace refer to ? 2- What cause/activity is at the origin of this source in the specific context of the case ? 3- What story can be told from these observations ? The stage 3 requires to reason in creating hypotheses that should explain the presence of the discovered trace coming from an activity ; the specific activity that is related to the investigated case. To validate this assumption, it would depend on their ability to respond to a rule of relevancy. The last step is the symbolisation of the relevancy. The rule would consist of two points : the recognition of the factual/circumstantial relevancy (Is the link between the trace and the case recognised with the formulated hypothesis ? ) and appropriate relevancy (What investment is required to collect and analyse the discovered trace considering the expected outcome at the investigation/intelligence level?). This process of meaning is based on observations and a conjectural reasoning subject to many influences. In this study, relevancy in forensic science is presented as a conventional dimension that is symbolised and conditioned by the context, the forensic investigator's practice and her workplace environment (culture of the place). In short, the current research states relevancy results of the interactions between parameters from situational, structural (or organisational) and individual orders. The detection, collection and analysis of relevant physical traces at scenes depends on the knowledge and culture mastered by the forensic investigator. In the study of the relation relevant trace-forensic investigator, this research introduces the KEE model as a conceptual map that illustrates three major areas of forensic knowledge and culture acquisition, involved in the research and evaluation of the relevant physical trace. Through the analysis of the investigation data and interviews, the relationship between those three parameters and the relevancy was highlighted. K, for knowing, embodies a rela- tionship to the immediate knowledge allowing to give an overview of the reality at a specific moment ; an important point since relevancy is signified in a context. E, for education, is considered through its relationship with relevancy via a culture that tends to become institutionalised ; it represents the theoretical knowledge. As for the parameter E, for experience, it exists in its relation to relevancy in the adjustments of the strategies of intervention (i.e a practical knowledge) of each practitioner having modulated her work in the light of success and setbacks case after case. The two E parameters constitute the library resources for the semiotic recognition process and the K parameter ensures the contextualisation required to set up the reasoning and to formulate explanatory hypotheses for the discovered physical traces, questioned in their relevancy. This research demonstrates that the relevancy is not absolute. It is temporal and contextual; it is a conventional and relative dimension that must be discussed. This is where the whole issue of the meaning of what is relevant to each stakeholder of the investigation process rests. By proposing a step by step approach to the meaning process from the physical trace to the forensic clue, this study aims to provide a more advanced understanding of the reasoning and its operation, in order to streng- then forensic investigators' training. This doctoral research presents a set of tools critical to both pedagogical and practical aspects for crime scene management while identifying key-influences with individual, structural and situational dimensions. - Une enquête criminelle consiste à rechercher et à faire parler les vestiges d'un acte incriminé passé. L'investigateur forensique se pose dans ce cadre comme un lecteur critique des lieux à la recherche de traces devant lui permettre de former son récit, soit l'histoire du délit/crime censé s'être produit. Le challenge de tout investigateur est de pouvoir détecter et reconnaître les traces dites pertinentes pour fournir des indices forensiques à buts d'enquête et de renseignement. Inspirée par un tel constat, la présente recherche pose au coeur de ses réflexions les questions suivantes : Qu'est-ce qu'une trace pertinente ? Et, comment fait le forensicien pour déterminer qu'il y fait face ? L'intérêt de tels questionnements se comprend dans la volonté de définir une dimension souvent utili- sée en science forensique, mais encore jamais étudiée dans ses implications et fonctionnements. Cette recherche se lance dans des voies d'étude encore peu explorées en usant d'outils sémiotiques et des pratiques d'enquêtes sociologiques combinés à des traitements statistiques de données. Les résultats sont représentés en suivant une piste sémiotique fortement influencée par les écrits de Peirce et une seconde piste dite empirique où des données d'interventions ont été analysées et des investigateurs forensiques interviewés sur leurs pratiques de travail sur le terrain. Par la piste sémiotique, une vision macroscopique du processus de signification de la trace en élément pertinent est représentée. La trace est perçue sous la forme de plusieurs signes dont la signification est codifiée culturellement. Le raisonnement se formaliserait en trois principales étapes : 1- Quel type de source évoque la trace détectée? 2- Quelle cause/activité est à l'origine de cette source dans le contexte précis du cas ? 3- Quelle histoire peut être racontée à partir de ces observations ? Cette dernière étape consiste à raisonner en créant des hypothèses devant expliquer la présence de la trace détectée suite à une activité posée comme étant en lien avec le cas investigué. Pour valider ces hypothèses, cela dépendrait de leur capacité à répondre à une règle, celle de la pertinence. Cette dernière étape consiste en la symbolisation de la pertinence. La règle se composerait de deux points : la reconnaissance de la pertinence factuelle (le lien entre la trace et le cas est-il reconnu dans l'hypothèse fournie?) et la pertinence appropriée (quel est l'investissement à fournir dans la collecte et l'exploitation de la trace pour le bénéfice attendu au niveau de l'investigation/renseignement?). Tout ce processus de signification se base sur des observations et un raisonnement conjectural soumis à de nombreuses influences. Dans cette étude, la pertinence en science forensique se formalise sous les traits d'une dimension conventionnelle, symbolisée, conditionnée par le contexte, la pratique de l'investigateur forensique et la culture du milieu ; en somme cette recherche avance que la pertinence est le fruit d'une interaction entre des paramètres d'ordre situationnel, structurel (ou organisationnel) et individuel. Garantir la détection, la collecte et l'exploitation des traces pertinentes sur les lieux dépend de la connaissance et d'une culture maîtrisées par le forensicien. Dans l'étude du rapport trace pertinente-investigateur forensique, la présente recherche pose le modèle SFE comme une carte conceptuelle illustrant trois grands axes d'acquisition de la connaissance et de la culture forensiques intervenant dans la recherche et l'évaluation de la trace pertinente. Par l'analyse des données d'in- terventions et des entretiens, le rapport entre ces trois paramètres et la pertinence a été mis en évidence. S, pour savoir, incarne un rapport à la connaissance immédiate pour se faire une représentation d'une réalité à un instant donné, un point important pour une pertinence qui se comprend dans un contexte. F, pour formation, se conçoit dans son rapport à la pertinence via cette culture qui tend à s'institutionnaliser (soit une connaissance théorique). Quant au paramètre E, pour expérience, il se comprend dans son rapport à la pertinence dans cet ajustement des stratégies d'intervention (soit une connaissance pratique) de chaque praticien ayant modulé leur travail au regard des succès et échecs enregistrés cas après cas. F et E formeraient la bibliothèque de ressources permettant le processus de reconnaissance sémiotique et S assurerait la contextualisation nécessaire pour poser le raisonnement et formuler les hypothèses explicatives pour les traces détectées et questionnées dans leur pertinence. Ce travail démontre que la pertinence n'est pas absolue. Elle est temporelle et contextuelle, c'est une dimension conventionnelle relative et interprétée qui se doit d'être discutée. C'est là que repose toute la problématique de la signification de ce qui est pertinent pour chaque participant du processus d'investigation. En proposant une lecture par étapes du processus de signification depuis la trace à l'indice, l'étude vise à offrir une compréhension plus poussée du raisonnement et de son fonctionnement pour renforcer la formation des intervenants forensiques. Cette recherche présente ainsi un ensemble d'outils critiques à portée tant pédagogiques que pratiques pour la gestion des lieux tout en identifiant des influences-clé jouées par des dimensions individuelles, structurelles et situationnelles.

De llibertat, autoritat i in/dependències (a la vida i l'obra de Maria-Mercè Marçal)

This article pays attention to two moments in the life and work (inseparably united) of Maria-Mercè Marçal. The first refers to a search of small objects presided by the moon. Taking this search as a motif, the freedom which the poet confers to the nocturnal light ¿mythical and magical symbol of femaleness- and, therefore, to that which symbolises the heavenly body, is revealed. The second moment revolves around the reflection of Marçal on the ¿female authority¿, a concept which this author, inspired by the philosophical community of Diotima, distinguishes from power. Throughout history, Maria-Mercè Marçal remarked, many women have gained strength from the free atribution of authority to other women, to their texts, to their experiences.

Totally implantable robot to treat chronic atrial fibrillation

Chronic atrial fibrillation affects millions of people worldwide. Its surgical treatment often fails to restore the transport function of the atrium. This study first introduces the concept of an atrial assist device (AAD) to restore the pump function of the atrium. The AAD is developed to be totally implantable in the human body with a transcutaneous energy transfer system to recharge the implanted battery. The ADD consists of a motorless pump based on artificial muscle technology, positioned on the external surface of the atrium to compress it and restore its muscular activity. A bench model reproduces the function of a fibrillating atrium to assess the circulatory support that this pump can provide. Atripump (Nanopowers SA, Switzerland) is a dome-shaped silicone-coated nitinol actuator 5 mm high, sutured on the external surface of the atrium. A pacemaker-like control unit drives the actuator that compresses the atrium, providing the mechanical support to the blood circulation. Electrical characteristics: the system is composed of one actuator that needs a minimal tension of 15 V and has a maximum current of 1.5 A with a 50% duty cycle. The implantable rechargeable battery is made of a cell having the following specifications: nominal tension of a cell: 4.1 V, tension after 90% of discharge: 3.5 V, nominal capacity of a cell: 163 mA h. The bench model consists of an open circuit made of latex bladder 60 mm in diameter filled with water. The bladder is connected to a vertically positioned tube that is filled to different levels, reproducing changes in cardiac preload. The Atripump is placed on the outer surface of the bladder. Pressure, volume and temperature changes were recorded. The contraction rate was 1 Hz with a power supply of 12 V, 400 mA for 200 ms. Preload ranged from 15 to 21 cm H(2)O. Maximal silicone membrane temperature was 55 degrees C and maximal temperature of the liquid environment was 35 degrees C. The pump produced a maximal work of 16 x 10(-3) J. Maximal volume pumped was 492 ml min(-1). This artificial muscle pump is compact, follows the Starling law and reproduces the hemodynamic performances of a normal atrium. It could represent a new tool to restore the atrial kick in persistent atrial fibrillation.

Gibbard's expressivism: an interdisciplinary critical analysis

This paper examines key aspects of Allan Gibbard's psychological account of moral activity. Inspired by evolutionary theory, Gibbard paints a naturalistic picture of morality mainly based on two specific types of emotion: guilt and anger. His sentimentalist and expressivist analysis is also based on a particular conception of rationality. I begin by introducing Gibbard's theory before testing some key assumptions underlying his system against recent empirical data and theories. The results cast doubt on some crucial aspects of Gibbard's philosophical theory, namely his reduction of morality to anger and guilt, and his theory of 'normative governance'. Gibbard's particular version of expressivism may be undermined by these doubts.
