Managing a software development project is a challenging task; time and effort is required to monitor the project's health and progress. In this context, organizations look for proposals that would assist them in this task. Recently a new and light alternative was introduced: ALPHAs, which are central elements of ESSENCE - Kernel and Language for Software Engineering Methods OMG standard. This paper...
The aim of this paper is to analyze available maturity models in the context of assessment of the maturity of IT systems that support communication processes in HCM. The paper presents theoretical issues connected with the evolution of information systems in context of support Human Capital Management (HCM) in a modern organization. Selected problems connected with assessment of maturity were presented,...
Global Software Development (GSD) poses inherent risks to projects success. Project managers are now faced with new challenges related to the geographical, temporal and socio-cultural distances between stakeholders. The objective of this research is to identify challenges associated with Software Project Management (SPM) activities in a GSD context and present an integrative framework encompassing...
Medical tourism is a domain rich of data that are stored in many hundreds of data sources. Many of these sources should be used during the development of tourism information systems. That is why, it is very important to create a referential model that represents the medical tourism in Tunisia. The e-tourism ontology provides a way to achieve integration and interoperability through the use of shared...
Time-memory trade-off methods provide means to invert one way functions. Such attacks offer a flexible trade-off between running time and memory cost in accordance to users' computational resources. In particular, they can be applied to hash values of passwords in order to recover the plaintext. They were introduced by Martin Hellman and later improved by Philippe Oechslin with the introduction of...
To maintain competitive advantage, today organizations need to be able to innovate - not just occasionally, but consistently. Mastering the process of innovation requires identifying the factors that support or hamper the achievement of innovations. The success of such process usually depends on the quality of the best opportunity identified, which is not enough. So, a systematic research and delivery...
This paper presents a method for the Weak Soundness verification of interorganizational workflow processes. The proposed method considers the Interorganizational WorkFlow nets theory and is based on the analysis of Linear Logic proof trees. To verify the Weak Soundness criterion, a Linear Logic proof tree is built for each different scenario of an unfolded Interorganizational WorkFlow net. These proof...
The identification of normative conflicts is an essential task in Multi-Agent Systems that are governed by multiple norms. Two norms are in conflict if they contradict each other, that is, when it is impossible to comply with both norms without a violation. Our work aims to present a means to detect normative conflicts that can only be detected when relationships among elements of different norms...
English has undoubtedly become the science and research lingua franca in the world in both oral and written communication. The capacity of English of scientists significantly affects the quality of research papers and presentations much more seriously than before. The global advancement of scientific research demands scientists to conduct oral presentations and write presentation slides by themselves...
This paper explores domain arguments—arguments about why techniques, processes, and designs possess properties as believed by their domain experts. An elicitation technique for their recovery from domain documents is presented. This is followed by demonstrated application of the technique to several domain artifacts from aviation engineering. The elicited arguments are presented and analyzed for their...
The effort to well define requirements early in a life cycle is one of the major challenges in engineering programs. Studies have shown that both technical and managerial factors influence requirements quality. However, despite the numerous requirements engineering techniques and methods, there is little knowledge of how to integrate them into a systematic requirements process that considers technical...
Engineers and information technology professionals often work in international settings or teams, as well as across diverse cultures in today's global economy. Ever expanding globalized society has required updates in organizational procedures and practices, especially for engineering and information technology organizations, to keep up with increasingly competitive and technology-oriented markets...
Formulation problem of algorithmization process of risk management using a conceptual model of risk management, reflecting the basic concepts of the semantic domain.
At many universities across the United States, the students' ideas resulting from course-associated work may not be their own, especially if they make "significant use" of university equipment or resources. But what does "significant use" mean for an undergraduate who is required to complete a unique design, in a team, for a grade? Is the design patentable? Licensable? Protected?...
There is little understanding of how and on what grounds people perceive or group Social Media Platforms (services) in which they participate into categories that can explain or predict their patterns of use. Some models are discussed and the possibilities of an ecological model are highlighted. This study examined how active users grouped social media platforms. 59 respondents completed an open card...
In the collaborative systems, in order to establish successful and protected collaboration, the trust management is first established between the participating entities and the trust score of each entity is calculated. This score is obtained based on the three trust criteria (satisfaction, reputation and recommendation) that are redefined and reused in our model: Tr-OrBAC. The evaluation of these...
The extensive diffusion of social media innovation has dramatically transformed traditional media content creation and dissemination with the effect of creating more user awareness. Citizens are increasingly becoming integral part of media content creation and dissemination and thus empowering citizens in the exercise of their informational self-determination. Ironically, in spite of the progress...
Researchers have shown that human decision making in complex environments like cyber is a significant risk factor. Unfortunately, much work on cyber situational awareness has been technology-focused, despite the ultimate importance of human decisions, especially in crisis situations like real-time cyber-attacks and data breaches. Cybersecurity practitioners and leaders require an appropriate framework...
In multi-agent systems, norms are being used to regulate the behavior of the autonomous agents. Norms describe the actions that can be performed, must be performed, and cannot be performed in the system. One of the main challenges on developing normative systems is that norms may conflict with each other. Norms are in conflict when the fulfillment of one norm violates the other and vice-versa. In...
Supporting group decision-making is a complex process, especially when decision-makers have no opportunity to gather at the same place and at the same time. Besides that, finding solutions may be difficult in case agents representing decision-makers are not able to understand the process and support them accordingly. In this work we present some topics of information that can be reported to decision-makers...
