Towards Consistency Management for a Business-Driven Development of SOA

The usage of the Service Oriented Architecture (SOA) along with the Business Process Management has emerged as a valuable solution for the complex (business process driven) system engineering. With a Model Driven Engineering where the business process models drive the supporting service component architectures, less effort is gone into the Business/IT alignment during the initial development activities, and the IT developers can rapidly proceed with the SOA implementation. However, the difference between the design principles of the emerging domainspecific languages imposes serious challenges in the following re-design phases. Moreover, enabling evolutions on the business process models while keeping them synchronized with the underlying software architecture models is of high relevance to the key elements of any Business Driven Development (BDD). Given a business process update, this paper introduces an incremental model transformation approach that propagates this update to the related service component configurations. It, therefore, supports the change propagation among heterogenous domainspecific languages, e.g., the BPMN and the SCA. As a major contribution, our approach makes model transformation more tractable to reconfigure system architecture without disrupting its structural consistency. We propose a synchronizer that provides the BPMN-to-SCA model synchronization with the help of the conditional graph rewriting

The effect of orthography on the recognition of pronunciation variants

published Online First October 24, 2019In conversational speech, it is very common for words’ segments to be reduced or deleted. However, previous research has consistently shown that during spoken word recognition, listeners prefer words’ canonical pronunciation over their reduced pronunciations (e.g., pretty pronounced [priti] vs. [priɾi]), even when the latter are far more frequent. This surprising effect violates most current accounts of spoken word recognition. The current study tests the possibility that words’ orthography may be 1 factor driving the advantage for canonical pronunciations during spoken word recognition. Participants learned new words presented in their reduced pronunciation (e.g., [trɒti]), paired with 1 of 3 spelling possibilities: (a) no accompanying spelling, (b) a spelling consistent with the reduced pronunciation (a reduced spelling, e.g., “troddy”), or (c) a spelling consistent with the canonical pronunciation (a canonical spelling, e.g., “trotty”). When listeners were presented with the new words’ canonical forms for the first time, they erroneously accepted them at a higher rate if the words had been learned with a canonical spelling. These results remained robust after a delay period of 48 hr, and after additional learning trials. Our findings suggest that orthography plays an important role in the recognition of spoken words and that it is a significant factor driving the canonical pronunciation advantage observed previously.This work was supported by the National Science Foundation Grant IBSS-1519908.

Introduction to Collaborative Technology for Coordinating Crisis Management (CT2CM) track

International audienceThis is the foreword introduction to the special Wetice Track about Coordination in Crisis Management and its support technology

Keynote : From group collaboration to large scale social collaboration

International audience25th years of evolution in collaborative technologies During the last 25th years, we have witnessed huge evolutions of technologies to support collaborative activities between people and between organisations. Since Doug Engelbart “Mother of all demos” in 1968, most of our dreams have come true regarding group support for collaboration, mobile and ubiquitous communication, and data sharing. We are now connected to anyone at anytime from almost anywhere and we can coordinate actions and share data to achieve common goals. In this talk, we will recall how a combination of advances in science and technologies, together with their appropriation by users, have created an exciting and unexpected landscape for collaboration. We will show how this landscape is still evolving under important tectonic forces driven by new discoveries, artefacts and usage. Although it is a risky exercise, we will try to draw some lines to the future to describe the evolution that is currently occurring in this area and how we expect to see them heading in the future : as an ubiquitous collaborative Web based platform where communities of people can collaborate confidently, as a system without central authority where they can meet, as a platform where they can share and coordinate their action to resolve the big issues of our time

O design de experiência como incentivo para despertar o engajamento à proteção animal

O presente trabalho consiste no desenvolvimento de um aplicativo voltado à proteção animal. A necessidade do desenvolvimento deste projeto surge a partir da identificação de que o mundo, com foco no Brasil, enfrenta um problema de superpopulação de animais abandonados, causando diversas problemáticas para a saúde pública. Este estudo tem como foco conscientizar a população geral em relação à causa animal e engajá-la a praticar essas mudanças. Para tanto, este trabalho propõe desenvolver um aplicativo que compreenda tanto conteúdos informativos, quanto ações que podem ser tomadas para apoiar ONGs e protetores independentes de animais. A primeira parte do trabalho aborda a introdução, justificativa do tema escolhido, seguido da definição dos objetivos geral e específicos. Após, é apresentada a fundamentação teórica acerca dos quatro principais assuntos que permeiam esse projeto: relação entre humanos e pets, proteção animal, colaboração e engajamento e design de experiência do usuário e interfaces. O desenvolvimento do trabalho baseia-se em uma metodologia adaptada a partir do Duplo Diamante da UK Design Council e de Unger e Chandler. Utilizando essa metodologia, o trabalho foi estruturado em quatro macro etapas: a etapa descobrir, etapa definir, etapa elaborar e por fim, a etapa entregar, onde foi desenvolvido um protótipo em alta fidelidade, assim como as conclusões realizadas do projeto.The present work consists of the development of an application aimed at animal protection. The relevance of this project comes from the fact that the world - with the focus around Brazil - is dealing with the overpopulation of abandoned animals, which is a problem in itself and causes even more problems for public health. This study is focused on bringing awareness to the general population, aiming for their engagement in practicing changes that will better serve the animal cause. Therefore, the proposition of this work is to develop an application that includes both informative content and actions that can be taken to support NGOs and independent animal protectors. The first part of the work deals with the introduction, justification of the chosen theme, followed by the definition of the general and specific objectives. Afterwards, the theoretical foundation on the four main subjects that permeate this project is presented: relationship between humans and pets, animal protection, collaboration and engagement, and user experience and interface design.The development of the work is based on a methodology adapted from the UK Design Council's Double Diamond and Unger and Chandler. Using this methodology, the work was structured into four macro stages: the discover stage, the define stage, the elaborate stage and finally, the deliver stage, where a high-fidelity prototype was developed, as well as the conclusions reached for the project

Metabolic and Proteomic Profiling of Diapause in the Aphid Parasitoid Praon volucre

Background: Diapause, a condition of developmental arrest and metabolic depression exhibited by a wide range of animals is accompanied by complex physiological and biochemical changes that generally enhance environmental stress tolerance and synchronize reproduction. Even though some aspects of diapause have been well characterized, very little is known about the full range of molecular and biochemical modifications underlying diapause in non-model organisms. Methodology/Principal Findings: In this study we focused on the parasitic wasp, Praon volucre that exhibits a pupal diapause in response to environmental signals. System-wide metabolic changes occurring during diapause were investigated using GC-MS metabolic fingerprinting. Moreover, proteomic changes were studied in diapausing versus nondiapausing phenotypes using a combination of two-dimensional differential gel electrophoresis (2D-DIGE) and mass spectrometry. We found a reduction of Krebs cycle intermediates which most likely resulted from the metabolic depression. Glycolysis was galvanized, probably to favor polyols biosynthesis. Diapausing parasitoids accumulated high levels of cryoprotective polyols, especially sorbitol. A large set of proteins were modulated during diapause and these were involved in various functions such as remodeling of cytoskeleton and cuticle, stress tolerance, protein turnover, lipid metabolism and various metabolic enzymes. Conclusions/Significance: The results presented here provide some first clues about the molecular and biochemical events that characterize the diapause syndrome in aphid parasitoids. These data are useful for probing potential commonality of parasitoids diapause with other taxa and they will help creating a general understanding of diapause underpinnings and a background for future interpretations

Human-Centric Process-Aware Information Systems (HC-PAIS)

Process-Aware Information Systems (PAIS) support organizations in managing and automating their processes. A full automation of processes is in particular industries, such as service-oriented markets, not practicable. The integration of humans in PAIS is necessary to manage and perform processes that require human capabilities, judgments and decisions. A challenge of interdisciplinary PAIS research is to provide concepts and solutions that support human integration in PAIS and human orientation of PAIS in a way that provably increase the PAIS users' satisfaction and motivation with working with the Human-Centric Process Aware Information System (HC-PAIS) and consequently influence users' performance of tasks. This work is an initial step of research that aims at providing a definition of Human-Centric Process Aware Information Systems (HC-PAIS) and future research challenges of HC-PAIS. Results of focus group research are presented.Comment: 8 page

Task Delegation Based Access Control Models for Workflow Systems

International audiencee-Government organisations are facilitated and conducted using workflow management systems. Role-based access control (RBAC) is recognised as an efficient access control model for large organisations. The application of RBAC in workflow systems cannot, however, grant permissions to users dynamically while business processes are being executed. We currently observe a move away from predefined strict workflow modelling towards approaches supporting flexibility on the organisational level. One specific approach is that of task delegation. Task delegation is a mechanism that supports organisational flexibility, and ensures delegation of authority in access control systems. In this paper, we propose a Task-oriented Access Control (TAC) model based on RBAC to address these requirements. We aim to reason about task from organisational perspectives and resources perspectives to analyse and specify authorisation constraints. Moreover, we present a fine grained access control protocol to support delegation based on the TAC model

Coordination of Distributed Collaborative Activities for Disaster Management

International audienceIt is very challenging for different organizations to coordinate together in dynamic situations like a disaster response. Each organization is autonomous and considers the situation from their point of view. There is no central authority to coordinate all operations. To coordinate their actions, organizations need to exchange information on what they are doing. However, they cannot share everything with everybody due to privacy, regulatory or strategic reasons. Currently, they only use e-mail, telephone or fax to exchange information. Thus, it is very difficult for them to detect and handle differences on their perception of the situation. We propose an approach for inter-organizational process management suited to these dynamic scenarios. It allows different organizations to share selected activities by replicating them optimistically in each other workspaces. The underlying system propagate the state changes to all workspace eventually. We explain detecting and handling of two different types of conflicts that can occur in this setting. We provide an implementation and explain how we have derived a first evaluation of the syste

Design of a Collaborative Disaster Response Process Management System

International audienceWe describe in this article a framework for disaster response process management. This framework can be used to develop information systems sup- porting those processes. It is grounded in several research approaches: literature research, case studies, end user interviews and workshops. We compare disaster response process management with business process management and argue why it is substantial different to it. Another main result of this comparison is that busi- ness process management technology, such as flexible workflow systems, are not suitable for disaster response processes. We propose an information system sup- porting disaster response processes based on our developed framework. Finally we present validation of the information system design and give outlook on our future research
