Auto-reflexividad, erografía y leitmotivs liminales en la producción narrativa de Mayra Santos-Febres (1995-2009)

La recherche, construction et révision de l’identité nationale ont très longtemps constitué les éléments propulseurs de la production littéraire et intellectuelle de Porto Rico. Pourtant vers le milieu des années 90, un nouveau consensus émerge entre les écrivains qui revendiquent massivement la fin de la littérature en tant que lieu d’où forger la conscience nationale et refuse le leadership intellectuel qui avait jusqu’alors définit le travail littéraire. Les auteurs qui commencent à se manifester à ce moment se désintéressent du nationalisme comme thème littéraire. Le militantisme politique et la volonté de confrontation, modes représentationnels caractéristiques de la génération antérieure, disparaissent pour laisser place à une écriture exploratoire, centrée sur ses propres procédés, et apparemment apolitique. Une telle perte d’ancrages nationaux et territoriaux est significative de la conscience exacerbée que possèdent ces écrivains de la complexité des dynamiques culturelles qui régissent le monde postmoderne et globalisé, ainsi que de la « valeur » et de la position « marginale » qu’on leur attribue dans l’écologie mass-médiatique culturelle actuelle. La production narrative de Mayra Santos-Febres est paradigmatique de ces changements. J’aborde dans son écriture une série de dispositifs métalittéraires, autoréflexifs, « érographiques », et historiographiques qui, bien qu’ils résistent à une catégorisation homogène, démontrent un même intérêt pour des phénomènes interstitiels. En me basant sur les concepts de liminalité, principalement depuis la perspective de Victor Turner et d’écriture auto-réflexive (Patricia Waugh, Linda Hutcheon), j’analyse le positionnement liminal qu’assume Santos-Febres dans la structure culturelle globalisée actuelle, et la façon dont sa prise de position, également liminale, c’est-à-dire, sa prise de parole et son engagement se traduisent par un rapprochement narcissique à l’exercice littéraire autant dans les formes qu’elle crée qu’au niveau sémantique, narratif et discursif. Le premier chapitre analyse les contes « Dilcia M. » et « Acto de Fe » (Pez de vidrio) comme témoignages de l’érosion du patriotisme et militantisme antérieur; « La escritora» (Pez de vidrio) qui marque pour l’auteure un passage vers une esthétique centrée sus ses propres procédés créatifs; et le roman Cualquier miércoles soy tuya qui dramatise le positionnement assumé par les écrivains dans la chaine culturelle globalisée actuelle. Le second chapitre aborde la configuration des corps, espaces urbains et de l’écriture dans El cuerpo correcto qui, à travers une exubérance sexuelle/textuelle, projette des variantes réactualisées de la traditionnelle dichotomie corps/écriture. Le troisième chapitre se penche sur la configuration du travesti dans Sirena Selena vestida de pena. J’y propose de voir le travestisme, le boléro et l’écriture comme un triple exercice métalittéraire. Le dernier chapitre aborde le procédé de re-signification littéraire des images sédimentées de subordination et d’infériorité de sujet « noir ». Nuestra Señora de la Noche se penche sur la re-signification de l’hyper-sexualisation et « exotisation » qui a cimenté la construction de « l’immoralité » de la femme noire. Fe en disfraz aborde le sadomasochisme comme espace de re-signification des schèmes de domination et soumission inscrits dans l’histoire esclavagiste de Porto Rico et du trauma qui origine, et subsiste, d’une telle hiérarchie.

Déterminer le lien entre l’hyperglycémie et/ou l’hypoinsulinémie et la dégradation clinique observée avant le diagnostic du Diabète Associé à la Fibrose Kystique.

La Fibrose kystique (FK) est une maladie génétique qui se traduit par une destruction progressive des poumons et éventuellement, à la mort. La principale complication secondaire est le diabète associé à la FK (DAFK). Une dégradation clinique (perte de poids et de la fonction pulmonaire) accélérée est observée avant le diagnostic. L’objectif principal de mon projet de doctorat est de déterminer, par l’intermédiaire du test d’hyperglycémie provoquée par voie orale (HGPO), s’il existe un lien entre l’hyperglycémie et/ou l’hypoinsulinémie et la dégradation clinique observée avant le diagnostic du DAFK. Nous allons ainsi évaluer l’importance des temps intermédiaires de l’HGPO afin de simplifier le diagnostic d’une dysglycémie ainsi que d’établir des nouveaux marqueurs indicateurs de patients à risque d’une détérioration clinique. L’HGPO est la méthode standard utilisée dans la FK pour le diagnostic du DAFK. Nous avons démontré que les valeurs de glycémie obtenues au temps 90-min de l’HGPO seraient suffisantes pour prédire la tolérance au glucose des patients adultes avec la FK, autrement établie à l’aide des valeurs à 2-h de l’HGPO. Nous proposons des glycémies à 90-min de l’HGPO supérieure à 9.3 mmol/L et supérieure à 11.5 mmol/L pour détecter l’intolérance au glucose et le DAFK, respectivement. Une cause importante du DAFK est un défaut de la sécrétion d’insuline. Les femmes atteintes de la FK ont un risque plus élevé de développer le DAFK que les hommes, nous avons donc exploré si leur sécrétion était altérée. Contrairement à notre hypothèse, nous avons observé que les femmes avec la FK avaient une sécrétion d’insuline totale plus élevée que les hommes avec la FK, mais à des niveaux comparables aux femmes en santé. Le groupe de tolérance au glucose récemment proposé et nommé indéterminé (INDET : 60-min HGPO > 11.0 mais 2h-HGPO <7.8mmol/L) est à risque élevé de développer le DAFK. Par contre, les caractéristiques cliniques de ce groupe chez les patients adultes avec la FK n’ont pas été établies. Nous avons observé que le groupe INDET a une fonction pulmonaire réduite et similaire au groupe DAFK de novo et aucun des paramètres glucidiques et insulinémiques expliqueraient cette observation. Dans une population pédiatrique de patients avec la FK, une association a été rapportée entre une glycémie élevée à 60-min de l’HGPO et une fonction pulmonaire diminuée. Dans notre groupe de patients adultes avec la FK, il existe une association négative entre la glycémie à 60-min de l’HGPO et la fonction pulmonaire et une corrélation positive entre l’insulinémie à 60-min de l’HGPO et l’indice de masse corporelle (IMC). De plus, les patients avec une glycémie à 60-min HGPO > 11.0 mmol/L ont une fonction pulmonaire diminuée et une sensibilité à l’insuline basse alors que ceux avec une insulinémie à 60-min HGPO < 43.4 μU/mL ont un IMC ainsi qu’une fonction pulmonaire diminués. En conclusion, nous sommes le premier groupe à démontrer que 1) le test d’HGPO peut être raccourci de 30 min sans compromettre la catégorisation de la tolérance au glucose, 2) les femmes avec la FK démontrent une préservation de leur sécrétion de l’insuline, 3) le groupe INDET présente des anomalies précoces de la fonction pulmonaire comparable au groupe DAFK de novo et 4) la glycémie et l’insuline à la première heure de l’HGPO sont associées aux deux éléments clefs de la dégradation clinique. Il est crucial d’élucider les mécanismes pathophysiologiques importants afin de mieux prévoir la survenue de la dégradation clinique précédant le DAFK.

Bionomics, cryopreservation of gametes and captive breeding behaviour of threatened hillstream cyprinid, garra surendranathanii(shaji, arun & easa, 1996)

Garra surendranathanii is a hill stream cyprinid endemic to Kerala. According to IUCN based classification, G. surendranathanii is grouped under the threatened category. This endemic fish is having highly restricted and fragmented distribution and reported only from 5 river systems viz. Chalakudy, Periyar, Pamba, Achenkoil and Bharathapuzha. Categorization of this fish as a potential ornamental candidate can invariably add more pressure on the threat status of this particular species. Hence, this species is considered as one which requires foremost attention for conservation. Hitherto, no infomiation is available on the bionomics, resource characteristics and any conservation attempts of G. surendranathanii. Studies on detailed life history traits and development of captive breeding technique are indispensable for successful fishery management.The present study was undertaken with the following obj ectives: To study the Length-weight relationship and condition factor to ascertain the relationship between length and weight and general wellbeing ofthe fish To study the age and growth to understand the age composition of the exploited stock, age at first maturation and life span of the species. To study the reproductive biology of G. surendranathanii to gain insights in the process of gametogenesis, spawning, sex ratio, fecundity and other related aspects which are essential for developing captive breeding technology of this species. To develop captive breeding technology and cryopreservation ofgametes of G. surendranathanii for conservation

Community Participation in Ecotourism: An Inclusive Development Option for Kerala

The inferences obtained from the study are presented in coherent area-specific levels so as to understand the ecotourism and its sub-sector areas for the researchers and policy makers about the issues, importances and potentialities of the sector. An analysis of the tourism sector in Kerala has shown tremendous growth both in terms of tourist arrivals and in terms of revenue generation from direct and indirect sources. The foreign tourist visitors in Kerala in 2014 was 9,23,336 which shows 7.60 percent increase from the last year and the domestic tourist visitors were 1,16,95,411 which again shows 7.71 percent increase, is a clear evidence of its potential. In 2014 the industry contributed revenue of 24885.44 crores from direct and indirect sources giving rise to an increase of 12.11 percent from the last year. A dichotomy of tourists and ecotourists shows that tourists in the ecotourism destinations come to 42.6 percent of the total, shows the scope, significance and its potential. Correlation of zone-wise tourist arrivals based on the ecotourism destinations highlights the fact that with only 19 of the 64 destinations that come in the central zone are the most preferred centres (around 54 percent) for the domestic as well as foreign tourists. The north zone encompassing 6 districts with rich biodiversity shows that the tourists‟ arrival patterns exhibit less promising results. Though the north zone has 31 ecotourism destinations of the state receives only 6.19 percent of the foreign visitors. The ecotourism activities in the state are primarily managed by the Eco-Development Committees (EDCs) and the Vana Samrakshana Samithies (VSS) under the Forest Development Agency of Kerala. Social class-wise categorization of membership shows that 13142 families have membership in 190 EDCs with SC (28 percent), ST (33 percent) and other marginalised communities (39 percent). But this in the VSS shows that 400 VSS have 59085 members actively engaged in ecotourism activities and social category of the VSS makes clear that majority are from the other marginalized fringe households with 62 percent where as the participation of SC is 12 percent and ST is 26 percent. An evaluation of the socio-economic and demographic matrix of the community members involved in ecotourism activities brings out region specific differences. About 75.70 percent of the respondents are males and the rest are females. Majority of the respondents (about 60 percent) are in the age group of 20 to 40 years, followed by the age group of 40-50 (20 percent). The average age of respondents in the three zones is between 35 and 37 years. The majority of the respondents are married, a few are unmarried. Average family size is 4-5 members and differences are identified among zones. Average number of adults per household is 3 and child per household is 2. Majority have an education of 10th class and below i.e. about 60 percent of the sample have only basic school education like primary, secondary and high school (i.e. up to SSLC but not passed) level. About 18 percent are SSLC passed, 10 percent are undergraduates whereas 6 percent constitute respondents having qualification of graduation and above. Majority of the „graduates and above‟ are from south and central zone. Inter-zone differences in educational profile are also identified with lesser number of „graduates and above‟ are identified in the north zone compared to the other two zones. Investigating into the income and livelihood options of the respondents gives insight about the prominence of ecotourism as an employment and livelihood option for the community members, as more than 90 percent of the respondents have cited tourism sector as their main employment option. Most (49.30 percent) of respondents get 100 percent income from tourism related activities, followed by 37.30 percent of community members have income between 75-99 percent from tourism whereas the rest (13 percent) have less than 74 percent of their income from tourism and there exists difference between zones and percentage of income. Financial habit shows that about 49.7 percent hold active bank accounts, 61 percent have savings behaviour and 73.8 percent have indebtedness. Analysis about the ownership of house brings to light that 37 percent of respondents live in their own house followed by 25.7 percent in government funded/provided house and 21 percent in their parent‟s house and 3.5 percent in rented house. About 12 percent of the respondents have other kinds of accommodation facilities such as staff quarters, etc. But in the case of north zone majority i.e. 52 percent primarily depend on the government funded house indicating the effectiveness of government housing programme. Standard of living measured in SLI frameworks shows that majority of the respondents have medium SLI values (42.3 percent); the remaining 47.7 percent have low SLI and 10 percent have high SLI. The community members have been benefitted immensely from forest and its resources. Since the ecotourism destinations are located amidst the wildlife settings, majority of them depend on forest for their livelihood. The information on the tourist‟s demographic characteristics like age, sex, educational qualification and annual income show that the age category of domestic and foreign tourists falls below the age group of less than 35 years (about 65 percent), whereas only 16 percent of tourists are aged above 46 years. The age group below 25 years consists of more international tourists (31.3 percent) compared to the proportion of domestic tourists (12.5 percent). Male-female ratio shows that the males constitute 56 percent of the sample and females with 44 percent. The factors determining the impact of ecotourism programmes in the community was evaluated with the aid of a factor analysis with 12 selected statements. The worries and concerns of the community members about the impact of ecotourism on the environment are well understood from this analysis. It can be drawn that environment protection and the role of ecotourism in improving the income and livelihood options of the local communities is the most important factor concerning the community members.

Capturing Emergent Semantics from Social Annotation Systems

The ongoing growth of the World Wide Web, catalyzed by the increasing possibility of ubiquitous access via a variety of devices, continues to strengthen its role as our prevalent information and commmunication medium. However, although tools like search engines facilitate retrieval, the task of finally making sense of Web content is still often left to human interpretation. The vision of supporting both humans and machines in such knowledge-based activities led to the development of different systems which allow to structure Web resources by metadata annotations. Interestingly, two major approaches which gained a considerable amount of attention are addressing the problem from nearly opposite directions: On the one hand, the idea of the Semantic Web suggests to formalize the knowledge within a particular domain by means of the "top-down" approach of defining ontologies. On the other hand, Social Annotation Systems as part of the so-called Web 2.0 movement implement a "bottom-up" style of categorization using arbitrary keywords. Experience as well as research in the characteristics of both systems has shown that their strengths and weaknesses seem to be inverse: While Social Annotation suffers from problems like, e. g., ambiguity or lack or precision, ontologies were especially designed to eliminate those. On the contrary, the latter suffer from a knowledge acquisition bottleneck, which is successfully overcome by the large user populations of Social Annotation Systems. Instead of being regarded as competing paradigms, the obvious potential synergies from a combination of both motivated approaches to "bridge the gap" between them. These were fostered by the evidence of emergent semantics, i. e., the self-organized evolution of implicit conceptual structures, within Social Annotation data. While several techniques to exploit the emergent patterns were proposed, a systematic analysis - especially regarding paradigms from the field of ontology learning - is still largely missing. This also includes a deeper understanding of the circumstances which affect the evolution processes. This work aims to address this gap by providing an in-depth study of methods and influencing factors to capture emergent semantics from Social Annotation Systems. We focus hereby on the acquisition of lexical semantics from the underlying networks of keywords, users and resources. Structured along different ontology learning tasks, we use a methodology of semantic grounding to characterize and evaluate the semantic relations captured by different methods. In all cases, our studies are based on datasets from several Social Annotation Systems. Specifically, we first analyze semantic relatedness among keywords, and identify measures which detect different notions of relatedness. These constitute the input of concept learning algorithms, which focus then on the discovery of synonymous and ambiguous keywords. Hereby, we assess the usefulness of various clustering techniques. As a prerequisite to induce hierarchical relationships, our next step is to study measures which quantify the level of generality of a particular keyword. We find that comparatively simple measures can approximate the generality information encoded in reference taxonomies. These insights are used to inform the final task, namely the creation of concept hierarchies. For this purpose, generality-based algorithms exhibit advantages compared to clustering approaches. In order to complement the identification of suitable methods to capture semantic structures, we analyze as a next step several factors which influence their emergence. Empirical evidence is provided that the amount of available data plays a crucial role for determining keyword meanings. From a different perspective, we examine pragmatic aspects by considering different annotation patterns among users. Based on a broad distinction between "categorizers" and "describers", we find that the latter produce more accurate results. This suggests a causal link between pragmatic and semantic aspects of keyword annotation. As a special kind of usage pattern, we then have a look at system abuse and spam. While observing a mixed picture, we suggest that an individual decision should be taken instead of disregarding spammers as a matter of principle. Finally, we discuss a set of applications which operationalize the results of our studies for enhancing both Social Annotation and semantic systems. These comprise on the one hand tools which foster the emergence of semantics, and on the one hand applications which exploit the socially induced relations to improve, e. g., searching, browsing, or user profiling facilities. In summary, the contributions of this work highlight viable methods and crucial aspects for designing enhanced knowledge-based services of a Social Semantic Web.

Development of thermo-analytical prediction and classification models for food in thermal devices using a multi sensor system and artificial neural networks

Die thermische Verarbeitung von Lebensmitteln beeinflusst deren Qualität und ernährungsphysiologischen Eigenschaften. Im Haushalt ist die Überwachung der Temperatur innerhalb des Lebensmittels sehr schwierig. Zudem ist das Wissen über optimale Temperatur- und Zeitparameter für die verschiedenen Speisen oft unzureichend. Die optimale Steuerung der thermischen Zubereitung ist maßgeblich abhängig von der Art des Lebensmittels und der äußeren und inneren Temperatureinwirkung während des Garvorgangs. Das Ziel der Arbeiten war die Entwicklung eines automatischen Backofens, der in der Lage ist, die Art des Lebensmittels zu erkennen und die Temperatur im Inneren des Lebensmittels während des Backens zu errechnen. Die für die Temperaturberechnung benötigten Daten wurden mit mehreren Sensoren erfasst. Hierzu kam ein Infrarotthermometer, ein Infrarotabstandssensor, eine Kamera, ein Temperatursensor und ein Lambdasonde innerhalb des Ofens zum Einsatz. Ferner wurden eine Wägezelle, ein Strom- sowie Spannungs-Sensor und ein Temperatursensor außerhalb des Ofens genutzt. Die während der Aufheizphase aufgenommen Datensätze ermöglichten das Training mehrerer künstlicher neuronaler Netze, die die verschiedenen Lebensmittel in die entsprechenden Kategorien einordnen konnten, um so das optimale Backprogram auszuwählen. Zur Abschätzung der thermische Diffusivität der Nahrung, die von der Zusammensetzung (Kohlenhydrate, Fett, Protein, Wasser) abhängt, wurden mehrere künstliche neuronale Netze trainiert. Mit Ausnahme des Fettanteils der Lebensmittel konnten alle Komponenten durch verschiedene KNNs mit einem Maximum von 8 versteckten Neuronen ausreichend genau abgeschätzt werden um auf deren Grundlage die Temperatur im inneren des Lebensmittels zu berechnen. Die durchgeführte Arbeit zeigt, dass mit Hilfe verschiedenster Sensoren zur direkten beziehungsweise indirekten Messung der äußeren Eigenschaften der Lebensmittel sowie KNNs für die Kategorisierung und Abschätzung der Lebensmittelzusammensetzung die automatische Erkennung und Berechnung der inneren Temperatur von verschiedensten Lebensmitteln möglich ist.

Learning Commonsense Categorical Knowledge in a Thread Memory System

If we are to understand how we can build machines capable of broad purpose learning and reasoning, we must first aim to build systems that can represent, acquire, and reason about the kinds of commonsense knowledge that we humans have about the world. This endeavor suggests steps such as identifying the kinds of knowledge people commonly have about the world, constructing suitable knowledge representations, and exploring the mechanisms that people use to make judgments about the everyday world. In this work, I contribute to these goals by proposing an architecture for a system that can learn commonsense knowledge about the properties and behavior of objects in the world. The architecture described here augments previous machine learning systems in four ways: (1) it relies on a seven dimensional notion of context, built from information recently given to the system, to learn and reason about objects' properties; (2) it has multiple methods that it can use to reason about objects, so that when one method fails, it can fall back on others; (3) it illustrates the usefulness of reasoning about objects by thinking about their similarity to other, better known objects, and by inferring properties of objects from the categories that they belong to; and (4) it represents an attempt to build an autonomous learner and reasoner, that sets its own goals for learning about the world and deduces new facts by reflecting on its acquired knowledge. This thesis describes this architecture, as well as a first implementation, that can learn from sentences such as ``A blue bird flew to the tree'' and ``The small bird flew to the cage'' that birds can fly. One of the main contributions of this work lies in suggesting a further set of salient ideas about how we can build broader purpose commonsense artificial learners and reasoners.

A Note on Object Class Representation and Categorical Perception

We present a novel scheme ("Categorical Basis Functions", CBF) for object class representation in the brain and contrast it to the "Chorus of Prototypes" scheme recently proposed by Edelman. The power and flexibility of CBF is demonstrated in two examples. CBF is then applied to investigate the phenomenon of Categorical Perception, in particular the finding by Bulthoff et al. (1998) of categorization of faces by gender without corresponding Categorical Perception. Here, CBF makes predictions that can be tested in a psychophysical experiment. Finally, experiments are suggested to further test CBF.

Computational Models of Object Recognition in Cortex: A Review

Understanding how biological visual systems perform object recognition is one of the ultimate goals in computational neuroscience. Among the biological models of recognition the main distinctions are between feedforward and feedback and between object-centered and view-centered. From a computational viewpoint the different recognition tasks - for instance categorization and identification - are very similar, representing different trade-offs between specificity and invariance. Thus the different tasks do not strictly require different classes of models. The focus of the review is on feedforward, view-based models that are supported by psychophysical and physiological data.

Towards a knowledge economy

This paper provides a preliminary formulation of a new currency based on knowledge. Through a literature review of alternative currencies, various properties and benefits are selected that we hope will enable such a currency to be created. Nowadays not only money but also knowledge is necessary to do business. For instance, knowledge about markets and consumers is highly valuable but difficult to achieve, and even more difficult to store, transport or trade. The basic premise of this proposal is a knowledge measurement pattern that is formulated as a new alternative social currency. Therefore, it is an additional means of contributing to the worldwide evolution of a knowledge society. It is intended as a currency to facilitate the conservation and storage of knowledge, and its organization and categorization, but mainly its exploitation and transference

Impacto de un curso teórico de mamografía en la categorización de microcalcificaciones de acuerdo al BI-RADS 4ed

Introducción: Por medio del presente estudio se busca determinar el impacto de un curso teórico de mamografía en la categorización de microcalficaciones mamarias. Materiales y métodos: Se realizó un estudio doble ciego para evaluar la variación de los valores predictivos positivos (VPP) de los descriptores morfológicos y de distribución de calcificaciones del BI-RADS 4ed, luego de un curso teórico de mamografía de 6 horas distribuido en 12 charlas semanales de 30 minutos. Se utilizó la base de datos de un estudio previo, en el cual dos radiólogos clasificaron las calcificaciones presentes en 108 mamografías de pacientes con diagnóstico histológico. Se realizó una nueva categorización de las calcificaciones según los descriptores. Se calcularon además, los valores kappa ponderados de concordancia intra e inter-observador, la sensibilidad y especificidad. Resultados: Para las calcificaciones de alta probabilidad de malignidad (pleomórficas finas y lineales ramificadas en conjunto), se obtuvieron VPP de 41 y 40%, con aumento leve respecto a la lectura inicial. El índice kappa ponderado para el acuerdo inter-observador fue de 0,305 lo que indica concordancia débil, con discreto incremento respecto a la evaluación inicial 0,260. La concordancia intra-observador para el evaluador 1 dio un valor kappa 0,471, moderada; y para el evaluador 2 un valor kappa 0,400, débil. Discusión: Un módulo teórico corto permite mejorar ligeramente la concordancia inter-observador en la evaluación de microcalcificaciones mamarias mediante el BI-RADS 4ed, así como los valores predictivos positivos de microcalficaciones de alta probabilidad de malignidad.

Efecto de la glicemia materna en la monitoría electrónica fetal

Introducción: Después del ingreso de la monitoría fetal electrónica como estudio de bienestar fetal, se ha considerado por décadas que un aporte de carbohidratos a la gestante antes de la realización de la monitoría fetal influye en el reporte pero existen estudios que consideran que los niveles de glicemia materna no afecta la variabilidad de la monitoría fetal. Metodología: Se realizó un estudio de corte transversal, para evaluar el efecto de la glicemia materna en la monitoría fetal electrónica comparando los valores de glicemia materna con su resultado, según la categorización del ACOG. Las principales variables fueron las horas de ayuno, valores de glicemia, variabilidad de la monitoría fetal y presencia de aceleraciones. Resultados: Se incluyeron un total de 60 pacientes, que ingresaron al servicio de obstetricia y ginecología del Hospital Universitario Mayor Méderi en el periodo de estudio. No se encontraron diferencias estadísticamente significativas entre los resultados de monitoría fetal y los valores de glicemia materna. Ninguna paciente presentó monitoría categoría III (según categorización de la ACOG). Discusión Se requieren estudios analíticos más amplios para evaluar el papel de la glicemia en el resultado de la monitoría, pero el presente estudio sugiere que no existe relación entre la glicemia materna y el resultado de la monitoría fetal electrónica en la categorización del Colegio Americano De Ginecología Y Obstetricia (ACOG).

La necesidad de establecer una condición jurídica para quienes deben migrar por causa de los desastres naturales : una realidad que atender desde la perspectiva de los derechos humanos

El incremento desmedido en el número de desastres naturales, sumado a la frecuencia con que estos ocurren a lo largo del mundo entero, ha evidenciado una de las mayores preocupaciones de los Estados: el desplazamiento forzado de la población por esta causa y la delicada situación de derechos humanos que esto implica, por lo cual los Organismos Internacionales han instado en reiteradas oportunidades a los Estados para actuar conjunta y prontamente para evitar que esta siga siendo una de las causas más altas de desplazamiento. Esta migración forzada pone de presente una problemática al no existir una posición universalmente aceptada sobre cuál es la condición jurídica de las personas que, por causa de los desastres naturales, deben dejarlo todo; la ausencia de esta categorización conlleva a la inexistencia de un marco legal internacional aplicable y con ello, a un vacío en la regulación interna de los Estados. Esta investigación pretende analizar los conceptos de migración existentes en el derecho internacional y establecer si la condición jurídica de quienes deben dejarlo todo por causa de los desastres naturales encaja dentro de alguna de estas categorías o si se hace necesario crear una nueva categoría que atienda las particularidades del contexto de este fenómeno migratorio, desde una perspectiva de derechos humanos. Para esto, se realizan reflexiones sobre tales conceptos así como un análisis de algunos casos de referencia, incluyendo la situación vivida en Colombia con la Ola Invernal de 2010, buscando realizar algunas propuestas de posibles soluciones jurídicamente viables.

Metacognitive knowledge and self-regulation: A qualitative lecture of students functioning in writing

This research emerges from the world-wide problematic concerning student's failure. It particularly analyzes the meta-cognitive competences in the writing process of this population. Based on Flavell's (1992) viewpoint about meta-cognition and the socio-cognitive approach of self-regulation, two variables were measured: meta-cognitive knowledge and self-regulation strategies. A qualitative study was conducted on a sample of 12 French students at first year university. This study uses a specific technique of interview known as "explicitation interview". The data analysis included the categorization, codification and quantification of the information obtained with the interviews. In conclusion, even though the students had metacognitive knowledge related to the written tasks, they did not show strategies that could help to go beyond the descriptive modality of written discourses by taking into account the readers' expectations. Their writing processes focused on transcription of ideas with little control on the planning and revision phases.
