    Identifying endophenotypes of schizophrenia is of critical importance and has profound implications on clinical practice. Here we propose an innovative approach to clarify the mechanims through which temperament and character deviance relates to risk for schizophrenia and predict long-term treatment outcomes. We recruited 61 antipsychotic naïve subjects with chronic schizophrenia, 99 unaffected relatives, and 68 healthy controls from rural communities in the Central Andes. Diagnosis was ascertained with the Schedules of Clinical Assessment in Neuropsychiatry; parkinsonian motor impairment was measured with the Unified Parkinson’s Disease Rating Scale; mesencephalic parenchyma was evaluated with transcranial ultrasound; and personality traits were assessed using the Temperament and Character Inventory. Ten-year outcome data was available for ~40% of the index cases. Patients with schizophrenia had higher harm avoidance and self-transcendence (ST), and lower reward dependence (RD), cooperativeness (CO), and self-directedness (SD). Unaffected relatives had higher ST and lower CO and SD. Parkinsonism reliably predicted RD, CO, and SD after correcting for age and sex. The average duration of untreated psychosis (DUP) was over 5 years. Further, SD was anticorrelated with DUP and antipsychotic dosing at follow-up. Baseline DUP was related to antipsychotic dose-years. Further, ‘explosive/borderline’, ‘methodical/obsessive’, and ‘disorganized/schizotypal’ personality profiles were associated with increased risk of schizophrenia. Parkinsonism predicts core personality features and treatment outcomes in schizophrenia. Our study suggests that RD, CO, and SD are endophenotypes of the disease that may, in part, be mediated by dopaminergic function. Further, SD is an important determinant of treatment course and outcome

    El caso de José María Arguedas

    This article aims to reflect on the self-translation of the Peruvian author José María Arguedas, by analysing the poem "Jetman, Haylli / Oda al jet", written in Quechua and translated into Spanish by the same author and compiled in Katatay / Temblar (1972). Arguedas, considering self-translation as a tool to translate the social and cultural heterogeneity of America, tells the image of a continent that demands a non-hierarchical dialogue with 'the West'. Self-translation is a form of cultural resistance against the hierarchies of power and representation according to which the indigenous would lose their 'authenticity' by coming into contact with modernity

    Este artigo aborda um aspecto relevante do ritual das refeiçÔes na corte de D. JoĂŁo VI, no Rio de Janeiro: a prataria de mesa. Isto Ă©, objetos de luxo destinados a servir e a consumir os alimentos. Com base em um inventĂĄrio de bens de mesa enviados do Rio de Janeiro para Lisboa junto com o monarca em seu retorno a Portugal, em 1821, este artigo procura refletir sobre as funçÔes e possĂ­veis usos desses objetos, assim como sobre a importĂąncia desse universo material para o funcionamento, representação e celebração da Casa Real portuguesa na sua nova sede. O artigo argumenta que a presença e o uso de baixelas de prata de serviço, mas tambĂ©m de grande aparato, nas refeiçÔes pĂșblicas da famĂ­lia real pode contribuir para se repensar a imagem de uma corte pobre e sem brilho recorrentemente reforçada na historiografia do perĂ­odo joanino.This article discusses a specific issue of the royal dinner's rituals at the Court of Rio de Janeiro: the silver service: some luxury artifacts of different forms specially made to serve and consume food. Based on a inventory of these silver objects and also on a stock of table linen which were shipped to Lisbon, along with the royal family in 1821, The article intend to explore the functions and utilities of those objects at the table, as well as, analyze the importance of this material universe for the functioning, representation and celebration of the Portuguese Royal House in its new headquarters.The article argues that the use and even the exhibition of the banquet silver in public ceremonies may contribute to change a rather depreciative image of poverty the royal court in Brazil, which has being explored by the historiography for more than a hundred years

    Patents, technological inputs and spillovers among regions

    No full text
    This article analyses the importance of different technological inputs (R&D and human capital) and different spillovers in explaining the differences in patenting among Spanish regions in the period 1986 to 2003. The analysis is based on the estimation of a knowledge production function. A region's own R&D activities and human capital are observed to have a positive significant effect on innovation output, measured by the number of patents. R&D spillovers weighted by the distance and the volume of trade flows between regions cause positive effects on a region's patents. However, distance matters more than the intensity of trade flows and the R&D spillover effects between regions are bounded: spillovers from closer regions perform better than spillovers from distant regions. On the opposite side, human capital spillovers do not cause any effect outside the region itself.
