Global Model Management in Eclipse GMT/AM3

International audienceWithin the GMT technology project (Generative Modeling Tools), an initial set of tools and artifacts for Global Model Management have recently been released under Eclipse. This paper presents the corresponding AM3 (ATLAS MegaModel Management) goals and contributions. AM3 is intended to provide support for modeling in the large, i.e. managing global resources in the field of MDE (Model-Driven Engineering). These global resources are usually heterogeneous and distributed. To access them without increasing the accidental complexity of MDE, we need to invent new ways to create, store, view, access, and modify the global entities that may be involved in developing a solution. To this intent, the notion of a megamodel (i.e. a model which elements are themselves models) is being used. This paper reports on the goals, the present state, and some future planned evolution of this Eclipse contribution

INRIA-ATLAS Response to the MDA Tool Capabilities OMG RFI

Proposition of answer from the INRIA-ATLAS team to the OMG Request For Information named "MDA Tool Capabilities"In the past years, the INRIA ATLAS Group has been building an MDA tool bench named AMMA (ATLAS Model Management Architecture). The present discusses the main characteristics and overall vision of this platform in the context of the OMG MDA Tool Capabilities RFI. In the following pages, we will provide an overall description of what MDA tool capabilities means for the ATLAS Group. We will show, within this response, how our overall Model-Driven Engineering (MDE) vision and implemented platform bring answers to the different RFI questions. We will also highlight the various MDA tool-specific needs and requirements we have already identified, even though some are not yet fully addressed by the current version of our platform.In a more organizational point of view, we have tried to follow as much as possible the logical sequence of the RFI proposed questions; however in many cases we have answered several questions at once. Our goal is not to answer exhaustively all the questions but more to cover all the different requirement areas

Validation of the Chinese version of the "Mood Disorder Questionnaire" for screening bipolar disorder among patients with a current depressive episode

<p>Abstract</p> <p>Background</p> <p>The Mood Disorder Questionnaire (MDQ) is a well-recognized screening tool for bipolar disorder, but its Chinese version needs further validation. This study aims to measure the accuracy of the Chinese version of the MDQ as a screening instrument for bipolar disorder (BPD) in a group of patients with a current major depressive episode.</p> <p>Methods</p> <p>142 consecutive patients with an initial DSM-IV-TR diagnosis of a major depressive episode were screened for BPD using the Chinese translation of the MDQ and followed up for one year. The final diagnosis, determined by a special committee consisting of three trained senior psychiatrists, was used as a 'gold standard' and ROC was plotted to evaluate the performance of the MDQ. The optimal cut-off was chosen by maximizing the Younden's index.</p> <p>Results</p> <p>Of the 142 patients, 122 (85.9%) finished the one year follow-up. On the basis of a semi-structured clinical interview 48.4% (59/122) received a diagnosis of unipolar depression (UPD), 36.9% (45/122) BPDII and 14.8% (18/122) BPDI. At the end of the one year follow-up,9 moved from UPD to BPD, 2 from BPDII to UPD, 1 from BPDII to BPDI, the overall rate of initial misdiagnosis was 16.4%. MDQ showed a good accuracy for BPD: the optimal cut-off was 4, with a sensitivity of 0.72 and a specificity of 0.73. When BPDII and BPDI were calculated independently, the optimal cut-off for BPDII was 4, with a sensitivity of 0.70 and a specificity of 0.73; while the optimal cut-off for BPDI was 5, with a sensitivity of 0.67 and a specificity of 0.86.</p> <p>Conclusions</p> <p>Our results show that the Chinese version of MDQ is a valid tool for screening BPD in a group of patients with current depressive episode on the Chinese mainland.</p
