N=1 domain wall solutions of massive type II supergravity and the issue of mirror symmetry

We report on Domain Wall solution of Calabi-Yau compactifications with general fluxes and their application to the study of mirror symmetry in generalized backgrounds. We address, in particular, to the issue of magnetic NSNS fluxes. We show that the Domain Wall gradient flow equations can be interpreted as a set of generalized Hitchin's flow equations of a manifold with SU(3)x SU(3) structure fibered along the direction transverse to the Domain wall.Comment: To appear in the proceedings of 2nd RTN Network Workshop and Midterm Meeting: Constituents, Fundamental Forces and Symmetries of the Universe, Naples, Italy, 9-13 Oct 200

localisation à l'étranger des entreprises multinationales.

La décision de localisation d'une entreprise multinationale peut être décrite comme une séquence de choix géographiques dans laquelle l'entreprise choisit d'abord un pays puis une région à l'intérieur de ce pays. Cette séquence de choix est confirmée par l'analyse du comportement des entreprises japonaises en Europe. La structure géographique du choix est prise en compte en séparant les déterminants du choix national et ceux du choix infra-national. Les entreprises multinationales ont tendance à se localiser dans les mêmes pays et dans les mêmes régions que leurs concurrentes. Cette tendance est plus forte à l'échelon régional qu'à l'échelon national. L'analyse des effets d'agglomération serait donc plus pertinente à une échelle géographique « fine ». L'influence des coûts du travail sur la décision de localisation est plus marquée au niveau régional. De plus, la concurrence entre les régions sur le plan des salaires joue plus à l'intérieur des pays qu'entre régions de pays différents.

How do firms agglomerate? A study of FDI in france

This paper studies the determinants of location choice by foreign investors in France using a sample of almost 4000 foreign investments over 10 years and 92 locations. Concerning agglomeration effects, we find very strong evidence of positive spillovers between firms, and identify detailed patterns of clustering, assessing, for instance, the countries of origin and the industries for which those spillovers are the most substantial. Concerning regional policies, we find very little evidence of any positive impact. Finally, we identify a 'learning process' of FDI, the location decisions becoming more remote from the country of origin during the period we study

Towards a linked information architecture for integrated law enforcement

Ponència presentada al Workshop on Linked Democracy: Artificial Intelligence for Democratic Innovation co-located with the 26th International Joint Conference on Artificial Intelligence (IJCAI 2017) celebrat el 19 d'agost de 2017 a Melbourne, AustraliaLaw enforcement agencies are facing an ever-increasing flood of data to be acquired, stored, assessed and used. Automation and advanced data analy-sis capabilities are required to supersede traditional manual work processes and legacy information silos by automatically acquiring information from a range of sources, analyzing it in the context of on-going investigations, and linking it to other pieces of knowledge pertaining to the investigation. This paper outlines a modular architecture for management of linked data in the law enforcement domain and discusses legal and policy issues related to workflows and infor-mation sharing in this context

Analysis of methods

Information is one of an organization's most important assets. For this reason the development and maintenance of an integrated information system environment is one of the most important functions within a large organization. The Integrated Information Systems Evolution Environment (IISEE) project has as one of its primary goals a computerized solution to the difficulties involved in the development of integrated information systems. To develop such an environment a thorough understanding of the enterprise's information needs and requirements is of paramount importance. This document is the current release of the research performed by the Integrated Development Support Environment (IDSE) Research Team in support of the IISEE project. Research indicates that an integral part of any information system environment would be multiple modeling methods to support the management of the organization's information. Automated tool support for these methods is necessary to facilitate their use in an integrated environment. An integrated environment makes it necessary to maintain an integrated database which contains the different kinds of models developed under the various methodologies. In addition, to speed the process of development of models, a procedure or technique is needed to allow automatic translation from one methodology's representation to another while maintaining the integrity of both. The purpose for the analysis of the modeling methods included in this document is to examine these methods with the goal being to include them in an integrated development support environment. To accomplish this and to develop a method for allowing intra-methodology and inter-methodology model element reuse, a thorough understanding of multiple modeling methodologies is necessary. Currently the IDSE Research Team is investigating the family of Integrated Computer Aided Manufacturing (ICAM) DEFinition (IDEF) languages IDEF(0), IDEF(1), and IDEF(1x), as well as ENALIM, Entity Relationship, Data Flow Diagrams, and Structure Charts, for inclusion in an integrated development support environment

Spent convictions and the architecture for establishing legal semantic workflows

This research was partially funded by the Data to Decisions Cooperative Research Centre (D2D CRC, Australia), and Meta-Rule of Law (DER2016- 78108-P, Spain)Operating within the Data to Decision Cooperative Research Centre (D2D CRC), the authors are currently involved in the Integrated Law Enforcement program and the Compliance through Design project. These have the goal of developing a federated data platform for law enforcement agencies that will enable the execution of integrated analytics on data accessed from different external and internal sources, thereby providing effective support to an investigator or analyst working to evaluate evidence and manage lines of inquiries in an investigation. Technical solutions should also operate ethically, in compliance with the law and subject to good governance principles. This paper is focused on the Australian spent convictions scheme, which provide use cases to test the platform
