The article is concerned with the formal definition of a largely unnoticed factor in narrative structure. Based on the assumptions that (1) the semantics of a written text depend, among other factors, directly on its visual alignment in space, that (2) the formal structure of a text has to meet that of its spatial presentation and that (3) these assumptions hold true also for narrative texts (which, however, in modern times typically conceal their spatial dimensions by a low-key linear layout), it is argued that, how ever low-key, the expected material shape of a given narrative determines the configuration of its plot by its author. The ,implied book' thus denotes an author's historically assumable, not necessarily conscious idea of how his text, which is still in the process of creation, will be dimensionally presented and under these circumstances visually absorbed. Assuming that an author's knowledge of this later (potentially) substantiated material form influences the composition, the implied book is to be understood as a text-genetically determined, structuring moment of the text. Historically reconstructed, it thus serves the methodical analysis of structural characteristics of a completed text.

Background: The high missed occult small bowel injuries (SBI) associated with laparoscopy in trauma (LIT) is a major reason why some surgeons still preclude LIT today. No standardized laparoscopic examination for evaluation of the peritoneal cavity is described for trauma. The objective of this article is to verify if a systematic standardized laparoscopic approach could correctly identify SBI in the peritoneal cavity for penetrating abdominal trauma (PAT). Methods: Victims with PAT were evaluated in a prospective, nonrandomized study. A total of 75 hemodynamically stable patients with suspected abdominal injuries were operated by LIT and converted to laparotomy if criteria were met: SBI and lesions to blind spot zones-retroperitoneal hematoma, injuries to segments VI or VII of the liver, or injuries to the posterior area of the spleen. Inclusion criteria were equivocal evidence of abdominal injuries or peritonea] penetration; systolic blood pressure >90 mm Hg and <3 L of IV fluids in the first hour of admission; Glasgow Coma Scale score >12; and age >12 years. Exclusion criteria were back injuries; pregnancy; previous laparotomy; and chronic cardiorespiratory disease. Results: Sixty patients were males and there were 38 stab wounds and 37 gunshot wounds. No SBI was missed, but a pancreatic lesion was undiagnosed due to a retroperitoneal hematoma. Twenty patients (26.6%) were converted. Unnecessary laparotomies were avoided in 73.33%. Therapeutic LIT was possible in 22.7%. Accuracy was 98.66% with 97.61% sensitivity and 100% specificity. Conclusions: Standard systematic laparoscopic exploration was 100% effective to detect SBI in the peritoneal cavity. Conversion from LIT to laparotomy should be done if injuries to blind spot zones are found which are poorly evaluated by LIT. Therapeutic LIT is feasible in PAT.

Au Québec, la Loi sur les services de santé et les services sociaux, Chapitre S-4.2, à son article 233, demande à ce que chacun des établissements de santé, dispose d’un code d’éthique qui essentiellement demande de préciser les droits des usagers et de fixer les conduites attendues du personnel. Le législateur souhaitait améliorer les conduites du personnel dès le début des années 1990 et envisageait désigner un organisme de surveillance pour s’en assurer. Cette contrainte ne fut pas retenue et 20 ans plus tard, la volonté d’assurer des conduites attendues n’est toujours pas assujettie de contraintes ou de contrôles même si elle est toujours souhaitée. En 2003 toutefois, le Ministre a mis en place un processus de visites ministérielles dans les milieux d’hébergement et à ce jour quelques 150 établissements ont été visités. Ces équipes se sont préoccupées entre autre de la fonction du code d’éthique pour soutenir les directions de ces établissements. Elles ne réussissent pas à pouvoir s’appuyer sur le code d’éthique pour qu’il soit l’assise pour baser les décisions cliniques, organisationnelles et de gestion de chacune des organisations du réseau de la santé et des services sociaux du Québec. Il faut à ce moment-ci faire le constat que le code d’éthique, obligatoire, figure au nombre des nombreuses contraintes rencontrées par les organisations. Les établissements doivent passer un processus d’agrément aux trois ans et le code d’éthique n’est pas davantage un élément dynamique retenu à ce processus de validation de normes de qualité. De plus, une revue québécoise spécialisée en gestion de la santé a consacré un numéro complet de 15 articles sur « éthique et comportements » et le code d’éthique y est absent sauf pour deux articles qui s’y attardent spécifiquement. Est-ce une question d’éthique dont il est question par ce code, ou si ce n’est pas davantage de la déontologie, d’autant que le législateur veut avant tout s’assurer de comportements adéquats de la part des employés et des autres personnes qui exercent leur profession. Est-ce qu’un code de conduite ne serait pas plus approprié pour atteindre les fins visées? Cette question est répondue dans ce mémoire qui regarde les concepts d’éthique, de déontologie, de codes, de régulation des comportements. De plus, des analyses détaillées de 35 codes d’éthique actuels de divers établissements et de diverses régions du Québec iv sont présentées. La littérature nous donne les conditions de réussite pour un code et outre l’importance à accorder aux valeurs énoncées dans l’organisation, il est également question des sanctions à prévoir au non-respect de ces valeurs. Elles se doivent d’être claires et appliquées. Enfin, beaucoup d’organisations parlent maintenant de code de conduite et ce terme serait tout à fait approprié pour rejoindre le souhait du législateur qui veut assurer des conduites irréprochables des employés et autres personnes qui y travaillent. C’est la conclusion de ce travail, énoncée sous forme de recommandation.

Due to the impacts of postcolonialism, social and cultural anthropology has been dealing intensively with the possibilities and limits of representing "other” human beings and their meaningful worlds. Scholars such as George Marcus, James Clifford or Clifford Geertz have discussed ways of improving anthropological methods of representation without, however, fully raising questions about the quality and validity of the objects represented and the very idea, that they could be “represented”. Thus, despite attempts to purify classical anthropological categories, substantialized presences (“Humans”, “Others”, “Pygmies” etc.), various forms of binary oppositions (us–them, culture–nature, human–animal) as well as certain epistemological modes/ logoi (representation, interpretation) have been rehearsed until today. The research aims to dissect and challenge the metaphysical outputs of the “anthropological machine” (Giorgio Agamben). I intended to solve these from their apparent familiarity as representable identities or differences in order to investigate their genealogy. In Derrida’s and Foucault’s understanding, genealogy becomes manifest mainly in the “blind spots” (Derrida) or “anomalies” (Foucault) between differences, at the borders of identities. As an analytical guideline, the research uses on one concrete metonym for the Derridean blind spot, one incorporation of a Foucauldian Other, namely pygmy narratives within early modern and 19th century imaginings. “Pygmies” have been part of both Western mythology and anthropological reflection since the antiquity and finally became “ethnographical facts” within an evolutionary anthropology in the 19th century during the European exploration of Africa. Throughout this veritable Odyssey, they were mostly precarious “category-jammers” (Timothy Beal), occupying the impossible middle grounds within (proto)anthropological classification. Thus, along with the early modern wild men, enfants sauvages or the apes of proto-primatology, the pygmies of the Homeric myth, as a catalyst for the negotiation of categories, played a decisive role in early modern and 19th century conceptions of the human. Through the precarious Pygmies, concrete socio-historical materializations of Identities (human, European), differences (human–animal etc.), as well as the accompanying logoi which vindicate these as pseudo-entities, appear evident. The research aims to read and write the history of early modern and 19th Century anthropology through one of its many classificatory constituting Others. It thus contributes to a discipline that for a long time has examined concrete systems of knowledge and the genealogy of classification in general. One might call it an “anthropologization” of anthropology.

This study adopts Ostrom’s Social-Ecological Systems (SES) framework in empirical fieldwork to explain how local forestry institutions affect forest ecosystems and social equity in the community of Mawlyngbna in North-East India. Data was collected through 26 semi-structured interviews, participatory timeline development, policy documents, direct observation, periodicals, transect walks, and a concurrent forest-ecological study in the village. Results show that Mawlyngbna's forests provide important sources of livelihood benefits for the villagers. However, ecological disturbance and diversity varies among the different forest ownership types and forest-based livelihood benefits are inequitably distributed. Based on a bounded rationality approach, our analysis proposes a set of causal mechanisms that trace these observed social-ecological outcomes to the attributes of the resource system, resource units, actors and governance system. We analyse opportunities and constraints of interactions between the village, regional, and state levels. We discuss how Ostrom’s design principles for community-based resource governance inform the explanation of robustness but have a blind spot in explaining social equity. We report experiences made using the SES framework in empirical fieldwork. We conclude that mapping cross-level interactions in the SES framework needs conceptual refinement and that explaining social equity of forest governance needs theoretical advances.

The Shopping centre is a long term investment in which Greenfield development decisions are often taken based on risks analysis regarding construction costs, location, competition, market and an expected DCF. Furthermore, integration between the building design, project planning, operational costs and investment analysis is not entirely considered by the investor at the decision making stage. The absence of such information tends to produce certain negative impacts on the future running costs and annual maintenance of the building, especially on energy demand and other occupancy expenses paid by the tenants to the landlord. From the investor´s point of view, this blind spot in strategy development will possibly decrease their profit margin as changes in the occupancy expenses[ ] have a direct outcome on the profit margin. In order to try to reduce some higher operating cost components such as energy use and other utility savings as well as their CO2 emissions, quite a few income properties worldwide have some type of environmental label such as BREEAM and LEED. The drawback identified in this labelling is that usually the investments required to get an ecolabel are high and the investor finds no direct evidence that it increases market value. However there is research on certified commercial properties (especially offices) that shows better performance in terms of occupancy rate and rental cost (Warren-Myers, 2012). Additionally, Sayce (2013) says that the certification only provides a quick reference point i.e. the lack of a certificate does not indicate that a building is not sustainable or efficient. Based on the issues described above, this research compares important components of the development stages such as investments costs, concept/ strategy development as well as the current investor income and property value. The subjects for this analysis are a shopping centre designed with passive cooling/bioclimatic strategies evaluated at the decision making stage, a certified regional shopping centre and a non-certified standard regional shopping centre. Moreover, the proposal intends to provide decision makers with some tools for linking green design features to the investment analysis in order to optimize the decision making process when looking into cost savings and design quality.

Human area V1 offers an excellent opportunity to study, using functional MRI, a range of properties in a specific cortical visual area, whose borders are defined objectively and convergently by retinotopic criteria. The retinotopy in V1 (also known as primary visual cortex, striate cortex, or Brodmann’s area 17) was defined in each subject by using both stationary and phase-encoded polar coordinate stimuli. Data from V1 and neighboring retinotopic areas were displayed on flattened cortical maps. In additional tests we revealed the paired cortical representations of the monocular “blind spot.” We also activated area V1 preferentially (relative to other extrastriate areas) by presenting radial gratings alternating between 6% and 100% contrast. Finally, we showed evidence for orientation selectivity in V1 by measuring transient functional MRI increases produced at the change in response to gratings of differing orientations. By systematically varying the orientations presented, we were able to measure the bandwidth of the orientation “transients” (45°).

Esta tese buscou estudar a integração entre a prospecção do futuro e projetos dentro do escopo da estratégia. Decisões envolvendo projetos no âmbito da estratégia das organizações são para horizontes de tempo de médio ou longo prazo. Nessa situação, gestores precisam lidar com incertezas de futuro, e para isso podem recorrer às metodologias de prospecção do futuro. O estudo do futuro é atividade complexa, pela abrangência de temas a serem considerados, contudo, é provável que gestores pratiquem essa atividade devido à responsabilidade assumida por suas decisões. A prática de metodologia prospectiva gera resultados, e estes podem contribuir nas decisões em projetos estratégicos. A literatura de estudos do futuro contém recomendações sobre como praticar metodologia prospectiva, porém aborda menos a utilização dos resultados de estudos prospectivos e a sua contribuição para a estratégia empresarial. Ela se concentra mais nos processos de desenvolvimento dos projetos de prospecção para se chegar aos resultados. Dessa forma, esta tese visou ao estudo da utilização dos resultados da prospecção nas decisões de projetos no âmbito da estratégia empresarial. Os fenômenos estudados envolvem a transição entre a prática da prospecção do futuro, a consequente disponibilidade de seus resultados e a contribuição dos mesmos nos processos de análise prospectiva para suporte a decisões. O objetivo geral da tese é a proposta de um modelo que contribua nessa transição. A metodologia utilizada foi mista - quantitativa e qualitativa - desenvolvida por meio de survey e entrevistas, e a abordagem utilizada foi exploratória e descritiva. Os resultados indicam haver limitações na integração entre prospecção do futuro e estratégia empresarial. Foi identificado que a prospecção do futuro é considerada importante pelos gestores participantes da pesquisa. Em contraste, a transição para a sua prática, passando pela disponibilidade de seus resultados, e a posterior utilização deles em processos de suporte à tomada de decisões em projetos estratégicos, apresenta limitações. Os resultados indicam que, apesar da importância da atividade de prospecção, gestores avaliam que ela é praticada em um nível mais baixo, e ao final a contribuição de seus resultados é avaliada em nível ainda mais baixo. Isso é mais evidente nas empresas de menor quantidade de funcionários, menor faturamento, de capital fechado ou limitado, sendo que nessas empresas a prospecção é para horizonte de tempo mais curto. Já gestores de empresas com maior quantidade de funcionários, maior faturamento e de capital aberto lidam melhor com a prospecção do futuro, sendo que estudam seus projetos estratégicos em horizonte de tempo mais longo. Observou-se que as principais limitações identificadas estão relacionadas com o conhecimento das metodologias de prospecção do futuro, e isso limita principalmente a identificação de temas importantes a serem estudados e monitorados acerca do futuro, configurando-se como lacunas de análise prospectiva ou pontos cegos. Por decorrência disso, a contribuição da prospecção na estratégia empresarial sofre limitações. Conclui-se, portanto, que a integração entre prospecção do futuro e a estratégia empresarial poderia ser facilitada por meio do uso de um modelo de suporte, voltado para: (1) reduzir a possibilidade de lacunas de análise prospectiva; e (2) suportar a avaliação: da prática da prospecção do futuro, do uso dos seus resultados nas decisões, e finalmente da aplicação da expertise sobre prospecção do futuro na empresa. Os resultados confirmam que o modelo proposto contribuiria na integração da prospecção do futuro com a estratégia empresarial.

This paper theorizes about the convergence of international organizations in global health governance, a field of international cooperation that is commonly portrayed as particularly hit by institutional fragmentation. Unlike existing theories on interorganizationalism that have mainly looked to intra- and extraorganizational factors in order to explain why international organizations cooperate with each other in the first place, the paper is interested in the link between causes and systemic effects of interorganizational convergence. The paper begins by defining interorganizational convergence. It then proceeds to discuss why conventional theories on interorganizational- ism fail to explain the aggregate effects of convergence between IOs in global (health) governance which tend to worsen rather than cushion fragmentation — so-called "hypercollective action" (Severino & Ray 2010). In order to remedy this explanatory blind-spot the paper formulates an alternative sociological institutionalist theory on interorganizational convergence that makes two core theoretical propositions: first that emerging norms of metagovernance are a powerful driver behind interorganizational convergence in global health governance, and secondly that IOs are engaged in a fierce meaning-struggle over these norms which results in hypercollective action. In its empirical part, the paper’s core theoretical propositions are corroborated by analyzing discourses and practices of interorganizational convergence in global health. The empirical analysis allows drawing two far-reaching conclusions. On the one hand, interorganizational harmonization has emerged as a largely undisputed norm in global health which has been translated into ever more institutionalized forms of interorganizational cooperation. On the other, discourses and practices of interorganizational harmonization exhibit conflicts over the ordering principles according to which the policies and actions of international organizations with overlapping mandates and missions should be harmonized. In combination, these two empirical findings explain why interorganizational convergence has so far failed to strengthen the global health architecture.
