    JAS-mine: A new platform for microsimulation and agent-based modelling

    Get PDF
    We introduce JAS-mine, a new Java-based computational platform that features tools to support the development of large-scale, data-driven, discrete-event simulations. JAS-mine is specifically designed for both agent-based and microsimulation modelling, anticipating a convergence between the two approaches. An embedded relational database management system provides tools for sophisticated input-output communications and data storage, allowing the power of relational databases to be used within an object-oriented framework. The JAS-mine philosophy encourages the separation of distinct concepts, objects and functionalities of the simulation model, and advocates and supports transparency, flexibility and modularity in model design. For instance, JAS-mine allows to store the list of regressors and their estimated coefficients externally to code, making it easy to change the specification of regression models used in the simulation and achieving a complete parallelisation between the tasks of the econometricians and those of the programmers. Moreover, tools for uncertainty analysis and search over the parameter space are also built in

    This article aims to problematize the micropolitical relationships produced in the Psychosocial Care Center (caps), Alegrete-RS, focusing on ethical principles in relation with customers and teamwork, identifying similarities and differences with the propositions of psychosocial care. This study follows a qualitative, descriptive and analytical approach. Interviews were conducted with users and workers, as well as participant observation. Aspects of subjective mobilization, innovation and the creation of relationships that produce ruptures in institutional practices were found, increasing subjectivation, negotiation, agency, resistance, and invention of various relationship and interaction devices in society, producing existential territories in the psychosocial care perspective. Micropolitical relations serve as agents for the production of meaning and the valorization of knowledges and enhancement of knowledge meaning, featuring an ethical stance regarding relationsEl artículo tiene como objetivo problematizar las relaciones micropolíticas producidas en el Centro de Atención Psicosocial (caps) de Alegrete-RS, enfoncando los principios éticos de las relaciones de los trabajadores con la clientela y en el trabajo en equipo, identificando las aproximaciones y los distanciamientos con las propuestas de atención psicosocial. Se trata de un estudio de abordaje cualitativo, descriptivo y analítico. Se realizaron entrevistas con los usuarios y trabajadores, y observación participante. Se encontraron aspectos de movilización subjetiva, innovación y creación de relaciones que producen rupturas en las prácticas institucionales, potencializando la subjetivación, los agenciamientos, las resistencias y la invención de diversos dispositivos de relación e interacción en la sociedad, produciendo territorios existenciales en la perspectiva de la atención psicosocial.

    Pure seminoma: A review and update

    Get PDF
    Pure seminoma is a rare pathology of the young adult, often discovered in the early stages. Its prognosis is generally excellent and many therapeutic options are available, especially in stage I tumors. High cure rates can be achieved in several ways: standard treatment with radiotherapy is challenged by surveillance and chemotherapy. Toxicity issues and the patients' preferences should be considered when management decisions are made. This paper describes firstly the management of primary seminoma and its nodal involvement and, secondly, the various therapeutic options according to stage

    Mining the human phenome using allelic scores that index biological intermediates

    J. Kaprio ja M-L. Lokki työryhmien jäseniä.It is common practice in genome-wide association studies (GWAS) to focus on the relationship between disease risk and genetic variants one marker at a time. When relevant genes are identified it is often possible to implicate biological intermediates and pathways likely to be involved in disease aetiology. However, single genetic variants typically explain small amounts of disease risk. Our idea is to construct allelic scores that explain greater proportions of the variance in biological intermediates, and subsequently use these scores to data mine GWAS. To investigate the approach's properties, we indexed three biological intermediates where the results of large GWAS meta-analyses were available: body mass index, C-reactive protein and low density lipoprotein levels. We generated allelic scores in the Avon Longitudinal Study of Parents and Children, and in publicly available data from the first Wellcome Trust Case Control Consortium. We compared the explanatory ability of allelic scores in terms of their capacity to proxy for the intermediate of interest, and the extent to which they associated with disease. We found that allelic scores derived from known variants and allelic scores derived from hundreds of thousands of genetic markers explained significant portions of the variance in biological intermediates of interest, and many of these scores showed expected correlations with disease. Genome-wide allelic scores however tended to lack specificity suggesting that they should be used with caution and perhaps only to proxy biological intermediates for which there are no known individual variants. Power calculations confirm the feasibility of extending our strategy to the analysis of tens of thousands of molecular phenotypes in large genome-wide meta-analyses. We conclude that our method represents a simple way in which potentially tens of thousands of molecular phenotypes could be screened for causal relationships with disease without having to expensively measure these variables in individual disease collections.Peer reviewe

    The drivers of inequality in rich countries

    No full text
    Rising income inequality has recently come centre-stage as a core societal concern for rich countries. The diagnosis of the forces driving inequality upwards and their relative importance remain hotly contested, notably with respect to the roles of globalization versus technology and of market forces versus institutions and policy choices. This survey provides a critical review and synthesis of recent research. The focus is on income inequality across the entire distribution, rather than only on what has been happening at the very top. We pay particular attention to include what has been learned from the analysis of micro-data, to ensure that the coverage is not unduly US-centric and to analyses of the interrelations between the different drivers of inequality. The marked differences in inequality trends across countries and time periods reflect how global economic forces such as globalization and technological change have interacted with differing national contexts and institutions. Major analytical challenges stand in the way of a consensus emerging on the relative importance of different drivers in how income inequality has evolved in recent decades

    A family-based study does not confirm the association of MYO9B with celiac disease in the Italian population

    Association between Myosin IXB (MYO9B) gene polymorphisms and celiac disease (CD) was recently detected by a case-control association study in the Dutch, but not confirmed in the British and Swedish/Norwegian populations. We tested the association between CD and the three most associated single nucleotide polymorphisms (SNPs) in the Dutch study by the transmission disequilibrium test in the Italian population. A total of 252 pediatric patients and 504 parents were genotyped. No transmission distortion was detected either for the single SNPs or for their haplotypic combinations. Control allele frequencies, calculated from untransmitted alleles, were significantly different from those of the Dutch control population. Conversely, allele frequencies were very similar in Italian, British, Swedish/Norwegian and Dutch patients. In conclusion, MYO9B is not involved in CD susceptibility in the Italian population. The difference with the Dutch result might be explained by an imperfect selection of the Dutch controls
