L'ansietat acadèmica i davant els exàmens com a fòbia específica de tipus situacional és un trastorn infantil i juvenil d'efectes pertorbadors i negatius que repercuteixen sobre la salut mental i emocional, el rendiment acadèmic i la integració social de l'estudiant que la pateix. En aquest treball s'especifiquen les seves característiques clíniques. Així mateix, s'inclou un cas clínic d'un adolescent de 14 anys que patia d'aquest trastorn fòbic escolar, acompanyat de baixa autoestima personal i dificultats d'adaptació amb el seu grup-classe. Se li va aplicar una avaluació i tractament de tall cognitiu-conductual que ha tingut com a finalitat la superació de la fòbia, i la millora del seu rendiment acadèmic i social. D'entre totes les eines terapèutiques utilitzades destaquen: l'exposició en viu, i l'aprenentatge i utilització de mecanismes de control de l'ansietat (la relaxació Jacobson i la reestructuració cognitiva). Finalment, assenyalar que aquesta intervenció terapèutica ha estat possible gràcies a la participació coordinada i cooperant de l'equip interdisciplinari.

Aplicación de un estudio de usabilidad en bibliotecas digitales : la Biblioteca Virtual de la UOC

The Open University of Catalonia (UOC) has conducted a study of operability of its user interfaces, creating for this purpose different work groups that have analyzed different casuistries. One of these groups focused on the study and analysis of the usability of the Virtual Library's website, with the objective of obtaining benefits for our users. As a result of this analysis, an important qualitative jump is occurring in the new implementation of the website of the UOC's Virtual Library, prioritizing the role of users from different points of view: ease of navigation, management of profiles and the services associated to these and the restructuring of the information architecture, with the final aim of facilitating access to the resources and the services offered from the Library, advocating in this way for their quality and improvement.

Contagion or Interdependence in the recent Global Financial Crisis? An application to the stock markets using unconditional cross-market correlations

We consider stock market contagion as a significant increase in cross-market linkages after a shock to one country or group of countries. Under this definition we study if contagion occurred from the U.S. Financial Crisis to the rest of the major stock markets in the world by using the adjusted (unconditional) correlation coefficient approach (Forbes and Rigobon, 2002) which consists of testing if average crossmarket correlations increase significantly during the relevant period of turmoil. We would not reject the null hypothesis of interdependence in favour of contagion if the increase in correlation only suggests a continuation of high linkages in all state of the world. Moreover, if contagion occurs, this would justify the intervention of the IMF and the suddenly portfolio restructuring during the period under study.

A Dethroned King? The Limits of State Infrastructural Power in France

Since the 1980s in Western Europe, centralized states' control over subnational territories has been deeply affected by processes of Europeanization and regionalization. These changes have raised the issue of state territorial restructuring in a particular fashion: what capacity have formerly centralized states retained to steer and control subnational territories? The article draws on Mann's concept of infrastructural power, which refers to the state's capacity to exercise control and implement political decisions over the national territory. The article applies the two main operationalizations of the concept, namely the capability of the state to exercise control and the weight of the state in the subnational territories. Empirically, the article focuses on the French state in two policy sectors (education and housing). Although France is a most likely case, this article challenges this expectation, and shows the limits of the French state's infrastructural power over the subnational territories since the late 1980s.

The distribution of tuberculosis in Porto Alegre: analysis of the magnitude and tuberculosis-HIV coinfection

Objective Analyzing the geographical distribution of the tuberculosis (TB), its incidence and prevalence and TB-HIV coinfection in the districts of Porto Alegre from 2007 to 2011. Method An ecological, descriptive study of time series that used descriptive and geoprocessing techniques. Results In total, were recorded 3,369 incident cases and 3,998 prevalent cases of pulmonary TB. In both contexts, there was predominance of cases in males and in Caucasians. Seventeen districts showed prevalence rates above 79.2 cases/100,000 inhabitants, considering that 15 of them had incidence rates above 73.7 cases/100,000 inhabitants. The TB-HIV coinfection rates reached 67% in some districts, which is above the city average value (30%). Conclusion The distribution analysis showed that the reformulation and restructuring of policies and health services in Porto Alegre are essential.


Long-term cerebral plasticity-related gene expression : a study of the respective role of CBP and CRTC1 in CREB transcriptional activation

1.1 AbstractThe treatment of memory disorders and cognitive deficits in various forms of mental retardation may greatly benefit from a better understanding of the molecular and cellular mechanisms of memory formation. Different forms of memory have distinct molecular requirements.Short-term memory (STM) is thought to be mediated by covalent modifications of existing synaptic molecules, such as phosphorylation or dephosphorylation of enzymes, receptors or ion channels. In contrast, long-term memoiy (LTM) is thought to be mediated by growth of new synapses and restructuring of existing synapses. There is extensive evidence that changes in gene expression and de novo protein synthesis are key processes for LTM formation. In this context, the transcription factor CREB (cAMP-response element-binding protein) was shown to be crucial. Activation of CREB requires phosphorylation of a serine residue (Ser-133), and the subsequent recruitment of a coactivator called CREB-binding protein (CBP). Moreover, we have recently shown that another coactivator called CREB Regulated Transcription Coactivator 1 (CRTC1) functions as a calcium- and cAMP-sensitive coincidence detector in neurons, and is involved in hippocampal long-term synaptic plasticity. Given the importance of cAMP and calcium signaling for plasticity-related gene expression in neurons and in astrocytes, we sought to determine the respective involvement of the CREB coactivators CBP and CRTC1 in CREB-mediated transcription.We developed various strategies to selectively interfere with these CREB coactivators in mouse primary neurons and in astrocytes in vitro. However, despite several pieces of evidence implicating CBP and/or CRTC1 in the regulation of neuronal plasticity genes, we could not clearly determine the respective requirement of these coactivators for the activation of these genes. Nevertheless, we showed that calcineurin activity, which is important for CRTC1 nuclear translocation, is necessary for the expression of some CREB-regulated plasticity genes. We associated this phenomena to physiopathological conditions observed in Down's syndrome. In addition, we demonstrated that in astrocytes, noradrenaline stimulates CREB-target gene expression through β-adrenergic receptor activation, intracellular cAMP pathway activation, and CRTC-induced CREB transactivation.Defining the respective role of CREB and its coactivators CBP and CRTC1 in neuronal and astrocytic cultures in vitro sets the stage for future in vivo studies and for the possible development of new therapeutic strategies to improve the treatment of memoiy and cognitive disorders.1.2 RésuméUne meilleure connaissance des mécanismes moléculaires et cellulaires responsables de la formation de la mémoire pourrait grandement améliorer le traitement des troubles de la mémoire ainsi que des déficits cognitifs observés dans différentes formes de pathologies psychiatriques telles que le retard mental. Les différentes formes de mémoire dépendent de processus moléculaires différents.La mémoire à court terme (STM) semble prendre forme suite à des modifications covalentes de molécules synaptiques préexistantes, telles que la phosphorylation ou la déphosphorylation d'enzymes, de récepteurs ou de canaux ioniques. En revanche, la mémoire à long terme (LTM) semble être due à la génération de nouvelles synapses et à la restructuration des synapses existantes. De nombreuses études ont permis de démontrer que les changements dans l'expression des gènes et la synthèse de protéine de novo sont des processus clés pour la formation de la LTM. Dans ce contexte, le facteur de transcription CREB (cAMP-response element-binding protein) s'est avéré être un élément crucial. L'activation de CREB nécessite la phosphorylation d'un résidu sérine (Ser-133), et le recrutement d'un coactivateur nommé CBP (CREB binding protein). En outre, nous avons récemment démontré qu'un autre coactivateur de CREB nommé CRTC1 (CREB Regulated Transcription Coactivator 1) agit comme un détecteur de coïncidence de l'AMP cyclique (AMPc) et du calcium dans les neurones et qu'il est impliqué dans la formation de la plasticité synaptique à long terme dans l'hippocampe. Etant donné l'importance des voies de l'AMPc et du calcium dans l'expression des gènes impliqués dans la plasticité cérébrale, nous voulions déterminer le rôle respectif des coactivateurs de CREB, CBP et CRTC1.Nous avons développé diverses stratégies pour interférer de façon sélective avec les coactivateurs de CREB dans les neurones et dans les astrocytes chez la souris in vitro. Nos résultats indiquent que CBP et CRTC1 sont tous deux impliqués dans la transcription dépendante de CREB induite par l'AMPc et le calcium dans les neurones. Cependant, malgré plusieurs évidences impliquant CBP et/ou CRTC1 dans l'expression de gènes de plasticité neuronale, nous n'avons pas pu déterminer clairement leur nécessité respective pour l'activation de ces gènes. Toutefois, nous avons montré que l'activité de la calcineurine, dont dépend la translocation nucléaire de CRTC1, est nécessaire à l'expression de certains de ces gènes. Nous avons pu associer ce phénomène à une condition physiopathologique observée dans le syndrome de Down. Nous avons également montré que dans les astrocytes, la noradrénaline stimule l'expression de gènes cibles de CREB par une activation des récepteurs β- adrénergiques, l'activation de la voie de l'AMPc et la transactivation de CREB par les CRTCs.Définir le rôle respectif de CREB et de ses coactivateurs CBP et CRTC1 dans les neurones et dans les astrocytes in vitro permettra d'acquérir les connaissances nécessaires à de futures études in vivo et, à plus long terme d'éventuellement développer des stratégies thérapeutiques pour améliorer les traitements des troubles cognitifs.

Credit derivatives in emerging markets

Credit Derivatives are securities that offer protection against credit or default risk ofbonds or loans. The credit derivatives emerging market has grown rapidly and creditderivatives are widely used. This paper describes the emerging credit derivativesmarket structure. The current market activity is analyzed through elementary pricingdynamics and the study of the term structure of default risk. Focusing on theperformance of credit derivatives in stress situation, including legal and market risks,we discuss the potential consequences of a debt restructuring in a large emergingmarket borrower. The contribution of credit derivatives to the risk sharing in emergingmarkets is also examined.

Cape Verdean Creole of São Vicente: Its genesis and Structure

Although the Santiago variety of Cape Verdean Creole (CVC) has been the subject of numerous linguistic works, the second major variety of the language, i.e. the São Vicente variety of CVC (CVSV), has hardly been described. Nevertheless this lack of studies and given its striking differences, on all linguistic levels, from the variety of Santiago (CVST), the implicit explanation for such divergences, echoed for decades in the literature on CVC, has been the presumably decreolized character of CVSV. First, this study provides a comprehensive fieldwork-based synchronic description of CVSV major morpho-syntactic categories in the intent to document the variety. Second, it aims to place the study of CVSV within a broader scope of contact linguistics in the quest to explain its structure. Based on analyses of historical documents and studies, it reconstructs the sociohistorical scenario of the emergence and development of CVSV in the period of 1797- 1975. From the comparison of the current structures of CVSV and CVST, the examination of linguistic data in historical texts and the analysis of sociohistorical facts it becomes clear that the contemporary structure of CVSV stems from the contact-induced changes that occurred during the intensive language and dialect contact on the island of São Vicente in the early days of its settlement in the late 18th and ensuing early 19th century development, rather than from modern day pressure of Portuguese. Although this dissertation argues for multiple explanations rather than a single theory, by showing that processes such as languages shift among the first Portuguese settlers, L2 acquisition, migration of the Barlavento speakers and subsequent dialect leveling as well as language borrowing at a later stage were at stake, it demonstrates the usefulness of partial-restructuring model proposed by Holm (2004).

Morphostructural characterization of soil conventionally tilled with mechanized and animal traction with and without cover crop

The structural stability and restructuring ability of a soil are related to the methods of crop management and soil preparation. A recommended strategy to reduce the effects of soil preparation is to use crop rotation and cover crops that help conserve and restore the soil structure. The aim of this study was to evaluate and quantify the homogeneous morphological units in soil under conventional mechanized tillage and animal traction, as well as to assess the effect on the soil structure of intercropping with jack bean (Canavalia ensiformis L.). Profiles were analyzed in April of 2006, in five counties in the Southern-Central region of Paraná State (Brazil), on family farms producing maize (Zea mays L.), sometimes intercropped with jack bean. The current structures in the crop profile were analyzed using Geographic Information Systems (GIS) and subsequently principal component analysis (PCA) to generate statistics. Morphostructural soil analysis showed a predominance of compact units in areas of high-intensity cultivation under mechanized traction. The cover crop did not improve the structure of the soil with low porosity and compact units that hamper the root system growth. In areas exposed to animal traction, a predominance of cracked units was observed, where roots grew around the clods and along the gaps between them.

ICD-11 for quality and safety: overview of the who quality and safety topic advisory group.

This paper outlines the approach that the WHO's Family of International Classifications (WHO-FIC) network is undertaking to create ICD-11. We also outline the more focused work of the Quality and Safety Topic Advisory Group, whose activities include the following: (i) cataloguing existing ICD-9 and ICD-10 quality and safety indicators; (ii) reviewing ICD morbidity coding rules for main condition, diagnosis timing, numbers of diagnosis fields and diagnosis clustering; (iii) substantial restructuring of the health-care related injury concepts coded in the ICD-10 chapters 19/20, (iv) mapping of ICD-11 quality and safety concepts to the information model of the WHO's International Classification for Patient Safety and the AHRQ Common Formats; (v) the review of vertical chapter content in all chapters of the ICD-11 beta version and (vi) downstream field testing of ICD-11 prior to its official 2015 release. The transition from ICD-10 to ICD-11 promises to produce an enhanced classification that will have better potential to capture important concepts relevant to measuring health system safety and quality-an important use case for the classification.

A global marine sedimentary response to the end-Permian mass extinction: Examples from southern Turkey and the western United States

The end-Permian mass extinction greatly diminished marine diversity and brought about a whole-scale restructuring of marine ecosystems; these ecosystem changes also profoundly affected the sedimentary record. Data presented here, attained through facies analyses of strata deposited during the immediate aftermath of the end-Permian mass extinction (southern Turkey) and at the close of the Early Triassic (southwestern United States), in combination with a literature review, show that sedimentary systems were profoundly affected by: (1) a reduction in biotic diversity and abundance and (2) long-term environmental fluctuations that resulted from the end-Permian crisis. Lower Triassic strata display widespread microbialite and carbonate seafloor fan development and contain indicators of suppressed infaunal bioturbation such as flat-pebble conglomerates and wrinkle structures (facies considered unusual in post-Cambrian subtidal deposits). Our observations suggest that depositional systems, too, respond to biotic crises, and that certain facies may act as barometers of ecologic and environmental change independent of fossil assemblage analyses. Close investigation of facies changes during other critical times in Earth history may serve as an important tool in interpreting the ecology of metazoans and their environment.

Gorilla genome structural variation reveals evolutionary parallelisms with chimpanzee

Structural variation has played an important role in the evolutionary restructuring of human and great ape genomes. Recent analyses have suggested that the genomes of chimpanzee and human have been particularly enriched for this form of genetic variation. Here, we set out to assess the extent of structural variation in the gorilla lineage by generating 10-fold genomic sequence coverage from a western lowland gorilla and integrating these data into a physical and cytogenetic framework of structural variation. We discovered and validated over 7665 structural changes within the gorilla lineage, including sequence resolution of inversions, deletions, duplications, and mobile element insertions. A comparison with human and other ape genomes shows that the gorilla genome has been subjected to the highest rate of segmental duplication. We show that both the gorilla and chimpanzee genomes have experienced independent yet convergent patterns of structural mutation that have not occurred in humans, including the formation of subtelomeric heterochromatic caps, the hyperexpansion of segmental duplications, and bursts of retroviral integrations. Our analysis suggests that the chimpanzee and gorilla genomes are structurally more derived than either orangutan or human genomes.
