The purpose of this paper is to elaborate a conceptual scheme for assessing deliberative spaces within political parties that propose the direct input of citizens in policy-making as a possible solution for the crisis that representative democracy is facing. Building on existing dimensions, we used a qualitative research design with data from observation, interviews and document analysis to investigate...
The purpose of this paper is to explore the importance of Information Technology (IT) Governance models for public organizations and presenting an IT Governance model that can be adopted by both practitioners and researchers. A review of the literature in IT Governance has been initiated to shape the intended theoretical background of this study. The systematic literature review formalizes a richer...
In this paper, we propose a decentralized Self-Adaptive Aggregation Mechanism (SAAM) that adapts itself to the supporting network operational behavior by dynamically selecting the best aggregation approach to use. SAAM is based on (1) a fuzzy-based model that estimates the cost and performance of each aggregation scheme and (2) Multiple Attribute Decision Making (MADM) to make decisions on the best...
Perception of one's environment is the first level in Endsley's three-part situational awareness (SA) development process critical for effective decision making. However, technological advances allow decision makers removed from the environment upon which they base their decisions to be increasing dependent upon indirect observations, or cues, provided by complex system of systems. One aspect of indirect...
Elaborating the project status for large-scale software projects is a very important task of the project manager due to the high need of control of such projects. Depending on the strategy used for elaborating the project status, the project manager has more or less information that they can further use in their decision-making process. In this paper we propose a classification of project status accuracy...
While there have been many advances in intelligent monitoring, it is still difficult to understand complex environments without human assistance. Rather than focus on fully automated monitoring, this work advocates user-centered analysis. A standardized analysis environment for visual fusion and embedding of information is developed called CANVAS (Contextual Activity Notification Visualization Analysis...
This paper proposes a governance decision-making framework for public health care systems. It encompasses and integrates data about family homes in a new intelligent health care information system. In order to support end-user interactions, the framework has been built on the GINGA middleware developed for the Brazilian Digital TV, whose full access will be country-wide in 2015. Based on five governance...
In ubiquitous network environment, network and resources change frequently, the capabilities of devices are quite different. All these features lead to local characteristics of QoS (quality of service). In addition, the centralized service registry and service selection methods cannot adapt to ubiquitous network environment. Therefore, this paper presents a decentralized Web services selection algorithm...
Trust is often calculated based on evidence which may come from a set of diverse sources. Challenges in trust calculation include the lack of a standard way to access evidence sources, lack of a standard for presenting evidence, unreliable evidence sources and differences of opinion on how evidence should be interpreted. This work shows that there are aspects of trust calculation that can be abstracted...
Promoting students success requires the implementation of processes and mechanisms that allows the closely monitoring of the students academic activities. Although essential, the activities involved in this complex process do not take place in many higher education institutions due to the lack of appropriate practices and an adequate technological support that sustain these practices. To overcome...
The paper provides a study of situation awareness mechanisms in modern telecommunication networks on the essential basis of the actual Self-NET research Project effort. Since cognition has today become one of the key features of most systems, novel mechanisms for identification, comprehension and corresponding reaction to altering environmental conditions are continuously being developed. The necessity...
We present a decision-level data fusion technique for monitoring and reporting critical health conditions of a hypertensive patient at home. Variables associated to the patient (physiological and behavioral) and to the living environment are considered in the solution, contributing to improve the confidence on the system outputs. In the paper, we model the problem variables as fuzzy, aiming to capture...
