Estuaries are areas which, from their structure, their fonctioning, and their localisation, are subject to significant contribution of nutrients. One of the objectif of the RNO, the French network for coastal water quality monitoring, is to assess the levels and trends of nutrient concentrations in estuaries. A linear model was used in order to describe and to explain the total dissolved nitrogen concentration evolution in the three most important estuaries on the Chanel-Atlantic front (Seine, Loire and Gironde). As a first step, the selection of a reliable data set was performed. Then total dissolved nitrogen evolution schemes in estuary environment were graphically studied, and allowed a resonable choice of covariables. The salinity played a major role in explaining nitrogen concentration variability in estuary, and dilution lines were proved to be a useful tool to detect outlying observations and to model the nitrogenlsalinity relation. Increasing trends were detected by the model, with a high magnitude in Seine, intermediate in Loire, and lower in Gironde. The non linear trend estimated in Loire and Seine estuaries could be due to important interannual variations as suggest in graphics. In the objective of the QUADRIGE database valorisation, a discussion on the statistical model, and on the RNO hydrological data sampling strategy, allowed to formulate suggestions towards a better exploitation of nutrient data.

This dissertation explores how two American storytellers, considered by many in their to be exemplary in their craft, rely on narrative strategies to communicate to their audiences on divisive political topics in a way that both invokes feelings of pleasure and connection and transcends party identification and ideological divides. Anna Quindlen, through her political columns and op-eds, and Aaron Sorkin, through his television show The West Wing, have won over a politically diverse fan base in spite of the fact that their writing espouses liberal political viewpoints. By telling stories that entertain, first and foremost, Quindlen and Sorkin are able to have a material impact on their audiences on both dry and controversial topics, accomplishing that which 19th Century writer and activist Harriet Farley made her practice: writing in such a way to gain the access necessary to “do good by stealth.” This dissertation will argue that it is their skilled use of storytelling elements, which capitalize on the cultural relationship humans have with storytelling, that enables Quindlen and Sorkin to achieve this. The dissertation asks: How do stories shape the beliefs, perspectives, and cognitive functions of humans? How do stories construct culture and interact with cultural values? What is the media’s role in shaping society? What gives stories their power to unite as a medium? What is the significance of the experience of reading or hearing a well-told story, of how it feels? What are the effects of Quindlen’s and Sorkin’s writing on audience members and the political world at large? What is lost when a simplistic narrative structure is followed? Who is left out and what is overlooked? The literature that informs the answers to these questions will cross over and through several academic disciplines: American Studies, British Cultural Studies, Communication, Folklore, Journalism, Literature, Media Studies, Popular Culture, and Social Psychology. The chapters will also explore scholarship on the subjects of narratology and schema theory.

Der vorliegende Aufsatz beschäftigt sich mit der Konzeption von Lern-Informationssystemen (LIS) unter besonderer Berücksichtigung der Verknüpfung von systematischem und fallorientiertem Lernen. Lern-Informationssysteme heben sich strukturell und funktional deutlich von den Lern-Managementsystemen (LMS) ab. Während ein LMS die administrativen Funktionalitäten stark betont, sehen die LIS ihren Schwerpunkt in der flexiblen und größtenteils dynamischen Bereitstellung von unterschiedlichen Anwendungsszenarien für den Lernenden. Erreicht wird die Dynamik und Flexibilität durch die Grundkonstrukte des LIS, die so genannten Module. Module enthalten neben dem zu vermittelnden Wissen Vor- und Nachbedingungen als logische Beschreibungen ihrer Inhalte bzw. der Voraussetzung ihrer Anwendbarkeit. Der Aufbau eines LIS wird anhand eines bestehenden und eingesetzten Lernsystems zum Thema der koronaren Herzkrankheit erklärt. Neben einer kurzen Einführung in die Theorie der LIS werden Anwendungsszenarien für systematisches Lernen und die Darstellung von Fällen und deren Verbindung zu Wissenseinheiten dargestellt. Für die Repräsentation der Daten eines Falles wird zurück gegriffen auf das an der Universität Regensburg entwickelte Fall-Schema MedicCaseML.(DIPF/Orig.)

The social landscape is filled with an intricate web of species-specific desired objects and course of actions. Humans are highly social animals and, as they navigate this landscape, they need to produce adapted decision-making behaviour. Traditionally social and non-social neural mechanisms affecting choice have been investigated using different approaches. Recently, in an effort to unite these findings, two main theories have been proposed to explain how the brain might encode social and non-social motivational decision-making: the extended common currency and the social valuation specific schema (Ruff & Fehr 2014). One way to test these theories is to directly compare neural activity related to social and non-social decision outcomes within the same experimental setting. Here we address this issue by focusing on the neural substrates of social and non-social forms of uncertainty. Using functional magnetic resonance imaging (fMRI) we directly compared the neural representations of reward and risk prediction and errors (RePE and RiPE) in social and non- social situations using gambling games. We used a trust betting game to vary uncertainty along a social dimension (trustworthiness), and a card game (Preuschoff et al. 2006) to vary uncertainty along a non-social dimension (pure risk). The trust game was designed to maintain the same structure of the card game. In a first study, we exposed a divide between subcortical and cortical regions when comparing the way these regions process social and non-social forms of uncertainty during outcome anticipation. Activity in subcortical regions reflected social and non-social RePE, while activity in cortical regions correlated with social RePE and non-social RiPE. The second study focused on outcome delivery and integrated the concept of RiPE in non-social settings with that of fairness and monetary utility maximisation in social settings. In particular these results corroborate recent models of anterior insula function (Singer et al. 2009; Seth 2013), and expose a possible neural mechanism that weights fairness and uncertainty but not monetary utility. The third study focused on functionally defined regions of the early visual cortex (V1) showing how activity in these areas, traditionally considered only visual, might reflect motivational prediction errors in addition to known perceptual prediction mechanisms (den Ouden et al 2012). On the whole, while our results do not support unilaterally one or the other theory modeling the underlying neural dynamics of social and non-social forms of decision making, they provide a working framework where both general mechanisms might coexist.

LGB teens’ feelings, desires, and physical attractions run contrary to the heteronormative standards of American society. As such, LGB youth often experience feelings of sadness and dejection that can lead to depression and suicidal tendencies (Russell & Joyner, 2001). Evaluating the factors that could possibly influence the emotional well-being of LGB youth would be an important undertaking given the hindrances LGB adolescents face during sexual socialization. The purpose of this dissertation was to study the portrayal of sexuality in media popular with LGB adolescents and to assess the relationship between media exposure and emotional well-being among LGB teens. In particular, this dissertation distinguished between mainstream media and gay- and lesbian-oriented (GLO) media. GLO media were defined as any media outlet specifically designed, produced, and marketed for gay and lesbian audiences. Two studies were conducted to serve as the initial investigation in a program of research that will be designed to better understand the role of media in the lives of LGB individuals. The first study of this dissertation was a content analysis of the television programs, films, songs, and magazines most popular with LGB teens as determined by self-reports of media consumption in a survey of media use. A total of 96 media vehicles composed the content analysis sample, including 48 television programs, 22 films, 25 musical artists, and 6 magazines. Using a coding scheme that was adapted from previous media sex research, Study 1 measured the frequency of sexual instances as well as the type, nature, and source characteristics for each sexual instance. Results of the content analysis suggest that heterosexuality reigns supreme in mainstream media. When LGB sexuality is depicted in mainstream media, it is often sanitized. LGB sexual talk is rarely sexual; rather it is primarily about the social or cultural components of being lesbian, gay, or bisexual. LGB sexual behavior is also rare in mainstream media, which tend to depict LGB individuals as non-sexually as possible. LGB sexuality in mainstream media exists, but is more about proclaiming LGB identity than actually living it. GLO media depicted LGB sexuality more frequently than mainstream media did. GLO media often depict LGB sexuality in a more realistic manner. LGB sexual talk is about LGB identity, as well as the relational and sexual aspects of being a sexual minority. LGB sexual behavior is commonplace in GLO media, depicting LGB individuals as sexual beings. LGB sexuality in GLO media is prevalent and relatively authentic. The second study was a survey that assessed the relationship between media exposure (both mainstream media and GLO media) and LGB teens’ emotional well-being, considering self-discrepancy as an important mediating variable in that relationship. Study 2 also considered age, sex, and sexual identity commitment as possible moderating variables in the relationship between media exposure and emotional well-being. In Study 2, emotional well-being was defined as lower levels of dejection-related emotions. LGB adolescents (N = 573) completed a questionnaire that was used to investigate the relationships between media exposure and emotional well-being. Results of the survey indicated that mainstream media exposure was not significantly associated with dejection-related emotions. In contrast, GLO media exposure was negatively related to feelings of dejection even when controlling for age, sex, race, perceived social support, school climate, religiosity, geographical location, sexuality of peers, and motivation for viewing LGB inclusive media content. Neither age nor sex moderated the relationships between media exposure variables and dejection, but sexual identity commitment did act as a moderator in the relationship between GLO media exposure and dejection. The negative relationship between GLO media exposure and dejection was stronger for participants lower in sexual identity commitment than for participants higher in sexual identity commitment. In addition, the magnitude of discrepancies between the actual self and the ideal self mediated the relationship between GLO media exposure and dejection for LGB adolescents low in sexual identity commitment. However, self-discrepancy did not mediate the relationship between GLO media exposure and dejection for LGB teens highly committed to their sexual identities. Results of both the content analysis and the survey are discussed in terms of implications for theory and method. Practical implications of this dissertation’s findings are also discussed, as well as directions for future research.

Este estudo propôs-se investigar, como os Esquemas Iniciais Desadaptativos (EIDs) concebidos pelo indivíduo e a sua representação dos Estilos Parentais (EPs), influenciam na escolha amorosa da vida adulta considerando os relacionamentos amorosos de reparação narcísica: Submisso-Idealizador, Eufórico-Idealizante e Evitante-Desnarcisante. A amostra constituiu-se por 225 (jovens) adultos/as portugueses/as, entre os 23 e 63 anos, que tivessem tido ou possuíssem na altura do estudo uma relação amorosa. A investigação de natureza quantitativa utilizou como instrumentos o: Inventário de Tipos de Relacionamento Amoroso (ITRA), Questionário de Esquemas (QE) e Questionário de Estilos Parentais (QEP). Segundo os resultados, evidenciou-se a associação de EIDs0F 1 e EPs1F 2 mais precoces e rígidos (incondicionais) aos três tipos de relacionamento amoroso, verificou-se uma herança psíquica trans-geracional com conteúdos individuais e relacionais mantidos e apurou-se a necessidade de o sujeito procurar relações fornecedoras de uma imagem mais completa do seu self desestruturado, concluindo-se que houve uma continuidade de relações falhadas; Abstract: A lifetime of failed relationships: continuity or change? Study about the psychic heritage and narcissistic unlove in adulthood. This study proposes to investigate, how the Early Maladaptive Schemas (EIDs) conceived by the individual and, their representation about the Parental Styles (EPs), influence the choice of adulthood loving relationships considering the romantic relationships of narcissistic repair: Submissive-Idealizer, Euphoric-Idealizing and Avoidant-Devaluate. The sample consisted of 225 Portuguese (young) adults, between 23 and 63 years old, who have had or maintained at the time of the study a loving relationship. The quantitative research used as instruments the: Inventory Types of Loving Relationship (ITRA), Schema Questionnaire (QE) and Parental Styles Questionnaire (QEP). According to the results, it showed the association of more early and rigid (unconditional) EIDs2F 3 and EPs3F 4 with the three types of love relationship, it was found a trans-generational psychic inheritance with individual and relational content maintained and found out the need for the subject pursuit for supplier relations of a more complete image of your self unstructured, concluding that there was a continuity of failed relationships.

Le mouvement derridien de la différance marque la rupture avec l'affirmation de la métaphysique de la présence, avec l'autorité du signifié transcendantal. Dans cet univers mouvant de signifiants qui se renvoient perpétuellement les uns aux autres, la logique d'univocité se disloque. La "présence" n'est que fantomatique, s'esquissant au sein d'une chaîne ininterrompue de signifiants et se laissant toujours creuser par la marque d'un irréductible manque. Face au logocentrisme, corollaire de l'affirmation de la présence, l'écriture se veut siège et articulation de la trace, d'une origine qui ne peut être que raturée, véhicule d'une irrémédiable fêlure. La volet littéraire de la déconstruction a pour but de mettre en évidence le fonctionnement de l'"indécidabilité" du discours, soit une certaine ambivalence dans la signification qui caractérise tout texte. L'objectif principal de la présente recherche est de fournir une compréhension plus approfondie de la déconstruction en insistant sur l'ancrage langagier de tout texte. Le discours philosophique n'échappe ainsi pas au mécanisme différentiel du langage et de la dérive métaphorique. La parenté entre la perspective déconstructiviste derridienne et la conception mallarméenne du langage poétique semble frappante. La mise en oeuvre, par Mallarmé, d'une dislocation de l'espace textuel, son minutieux "creusement" du vers après renoncement à toute quête d'"Idéal", la mise en relief du leurre de l'appropriation langagière, voilà qui trouve un écho particulier dans les thèses derridiennes. La "mimésis" platonicienne se voit au travers du prisme de la "mimique" mallarméenne. La déconstruction poursuit son travail de "luxation" de l'oreille philosophique, insérant les philosophèmes dans la matrice langagière, les livrant ainsi au hasard du cheminement textuel et les confrontant à l'aporie. La philosophie n'a alors d'autre choix que d'abandonner ses prétentions transcendantales. La marche de la "différance" instaure une inexorable distance qui prive le sujet de tout rapport direct avec une origine assurée et lui ôte toute possibilité de maîtrise sur le monde. Au travers de la langue, se profile la question de l'altérité, de la relation dissymétrique qui nous lie à cet "autre", ce "tout-autre" qui nous fonde et nous constitue. L'accueil inconditionnel de cette altérité nous mènera à l'étude de la "religion", la déconstruction se tournant vers le "religieux" tout en effectuant un "retournement" habile de tout credo essentialiste.

The main contribution of this special issue is to present evaluation studies involving large-scale experiences of implementation of positive parenting programs delivered through home, group-based, and on-line formats in Spain. Two research questions were addressed: (1) what factors affect implementation; and (2) for whom and under which implementation conditions the programs lead to positive outcomes. Target populations were mainly families from low and middle socioeconomic backgrounds, and parents at psychosocial risk attending family support services in need of improving their parenting skills. All the programs fall under the umbrella of the positive parenting initiative launched by the Council of Europe, are evidence-based, follow a collaborative schema with national, regional, or local authorities, have multi-site implementation, and are supported by highly experienced researchers from Spanish universities. Special attention is given to the program adaptations to different contexts, the profile of parents who benefited most from the programs, analyses of the implementation process, and the assessment of parenting programs in the community. The information provided will help to increase our knowledge of evidence-based parenting programs in Spain, their implementation processes and results, and the future challenges that need to be addressed to continue the current expansion of evidence-based parenting programs.

Designed as a quick and easy tool to help assess the essential traits of the social and therapeutic atmosphere in forensic psychiatric settings (subsequently expanded for use in correctional facilities), the Essen Climate Evaluation Schema (EssenCES) was originally developed and first published in Germany. It has since been translated into a number of other languages and been included in a considerable number of studies, among them a broad validation study in the UK. Following this study andthe UK Commissioning for Quality and Innovation (CQUIN) initiating the regular use of the scale in forensic psychiatric services in the UK, we have received a large number of enquiries regarding support in using the scale and interpreting its findings. In particular, many researchers and clinicians have requested reference norms that would allow them to compare the EssenCES scores obtained in their particular unit/service with the scores obtained in other settings. This manual aims to respond to these enquiries. It outlines the background and the concept of the instrument and discusses the variety of ways in which the EssenCES might be used to support research and practice within forensic services.It also includes considerations regarding the limitations of previous studies that have utilised the concept of social climate and a discussion of how the contribution of climate evaluations might be further improved in the future.

The idea of meta-cognitive learning has enriched the landscape of evolving systems, because it emulates three fundamental aspects of human learning: what-to-learn; how-to-learn; and when-to-learn. However, existing meta-cognitive algorithms still exclude Scaffolding theory, which can realize a plug-and-play classifier. Consequently, these algorithms require laborious pre- and/or post-training processes to be carried out in addition to the main training process. This paper introduces a novel meta-cognitive algorithm termed GENERIC-Classifier (gClass), where the how-to-learn part constitutes a synergy of Scaffolding Theory - a tutoring theory that fosters the ability to sort out complex learning tasks, and Schema Theory - a learning theory of knowledge acquisition by humans. The what-to-learn aspect adopts an online active learning concept by virtue of an extended conflict and ignorance method, making gClass an incremental semi-supervised classifier, whereas the when-to-learn component makes use of the standard sample reserved strategy. A generalized version of the Takagi-Sugeno Kang (TSK) fuzzy system is devised to serve as the cognitive constituent. That is, the rule premise is underpinned by multivariate Gaussian functions, while the rule consequent employs a subset of the non-linear Chebyshev polynomial. Thorough empirical studies, confirmed by their corresponding statistical tests, have numerically validated the efficacy of gClass, which delivers better classification rates than state-of-the-art classifiers while having less complexity.

The importance of mobile application specific testing techniques and methods has been attracting much attention of software engineers over the past few years. This is due to the fact that mobile applications are different than traditional web and desktop applications, and more and more they are moving to being used in critical domains. Mobile applications require a different approach to application quality and dependability and require an effective testing approach to build high quality and more reliable software. We performed a systematic mapping study to categorize and to structure the research evidence that has been published in the area of mobile application testing techniques and challenges that they have reported. Seventy nine (79) empirical studies are mapped to a classification schema. Several research gaps are identified and specific key testing issues for practitioners are identified: there is a need for eliciting testing requirements early during development process; the need to conduct research in real-world development environments; specific testing techniques targeting application life-cycle conformance and mobile services testing; and comparative studies for security and usability testing.

Scientific workflow is a complicated data intensive application. How to achieve an effective data placement schema in hybrid cloud environment has become a crucial issue nowadays, especially with the new challenges brought by the security issues. Traditional data placement strategies usually adopt load balancing-based partition model to allocate datasets. Although these data placement schemas can have good performance in load balancing, their data transfer time may not be optimal. In contrast to traditional strategies, this paper focuses on the hybrid cloud environment and proposes a data dependency destruction-based partition model to achieve the minimal data dependency destruction partition. In addition, it presents a novel datacenter-oriented data placement strategy. This strategy allocates high dependency datasets to one datacenter according to the new partition model and thus significantly reduces data transfer time between datacenters. Experimental results show that the proposed strategy can effectively reduce data transfer time during workflow's execution.

L’émergence du postmodernisme aux Etats-unis, mouvement esthétique rejetant les dogmes modernistes, date des années 1960. En s’imposant, durant les dernières décennies du 20ème siècle, comme le paradigme esthétique de l’architecture, des arts et de la littérature, le postmodernisme a également créé les conditions propres à une renaissance du roman historique. Cependant, la fiction historique postmoderne constitue maintenant une nouvelle forme du genre basée sur la parodie, l’ironie et le scepticisme envers les discours dominants. Cette nouvelle forme ne se limite plus à la présentation des récits dans un cadre historique réaliste. Elle remet plutôt en question la validité et par conséquent la nature même du discours historique, problématisant et mettant ainsi à l’avant le processus d’interprétation et de reconstruction du passé. Dans cette optique, la fiction historique contemporaine reflète les débats actuels sur les formes de l’historiographie, débats lancés par Hayden White. Dans les années 1980, la fiction historique a de nouveau fleuri dans l'espace culturel allemand tout comme ailleurs. Le présent mémoire analyse des formes postmodernes de la fiction historique en se basant sur trois romans historiques de langue allemande parus entre 1981 et 2005: Die Schrecken des Eises und der Finsternis de Christoph Ransmayr, Die Vermessung der Welt de Daniel Kehlmann et Marbot : Eine Biographie de Wolfgang Hildesheimer. L’analyse s'appuie sur divers modèles de la fiction postmoderne, en particulier sur le schéma de catégorisation du roman historique élaboré par Ansgar Nünning. Le mémoire montre dans quelle mesure ces romans appliquent des moyens stylistiques typiques pour le postmodernisme et portent un regard critique ou comique sur l’histoire et la culture allemande et autrichienne.
