Streaming the Web: Reasoning over dynamic data.

In the last few years a new research area, called stream reasoning, emerged to bridge the gap between reasoning and stream processing. While current reasoning approaches are designed to work on mainly static data, the Web is, on the other hand, extremely dynamic: information is frequently changed and updated, and new data is continuously generated from a huge number of sources, often at high rate. In other words, fresh information is constantly made available in the form of streams of new data and updates. Despite some promising investigations in the area, stream reasoning is still in its infancy, both from the perspective of models and theories development, and from the perspective of systems and tools design and implementation. The aim of this paper is threefold: (i) we identify the requirements coming from different application scenarios, and we isolate the problems they pose; (ii) we survey existing approaches and proposals in the area of stream reasoning, highlighting their strengths and limitations; (iii) we draw a research agenda to guide the future research and development of stream reasoning. In doing so, we also analyze related research fields to extract algorithms, models, techniques, and solutions that could be useful in the area of stream reasoning. © 2014 Elsevier B.V.

A survey on competitive intelligence practices for strategic decisions

Doutoramento em GestãoThis thesis aims to measure the frequency use of competitive intelligence as a support tool to the strategic decision-making in Portuguese organizations. Likewise, the thesis aims to measure the satisfaction level of the decision-maker when making decisions based on competitive intelligence. Based on an extensive literature review, some hypotheses appear to support a survey addressing competitive intelligence issues. Considering a convenient sample, the conclusions drawn about the use and satisfaction level based on competitive intelligence are as expected, as what lies beneath strategic decisions is also answered.Esta tese tem o objectivo de medir a frequência do uso de competitive intelligence como ferramenta de suporte à tomada de decisão estratégica nas empresas Portuguesas. De igual modo, tem o objectivo de medir o grau de satisfação dos decisores quando tomam decisões baseadas em competitive intelligence. Com base numa extensa revisão de literatura, surgem algumas hipóteses que suportam um inquérito sobre competitive intelligence. Considerando uma amostra de conveniência, as conclusões tiradas são as esperadas, e obtém-se a resposta para o que está por detrás da decisão estratégica.info:eu-repo/semantics/publishedVersio

Aligning Performance Management Systems for Lasting Outcomes in Humanitarian Operations

Logistics is dynamic, expansive, and critical to organizational success. While it is generally believed that effective logistics management is associated with positive performance outcomes, the links between organizational practice and performance are understudied. This dissertation leverages resource-based theory and organizational learning theory to examine organizational practice and performance in non-traditional logistics settings, with particular focus on military organizations and humanitarian operational settings. First, a meta-analytical study establishes generalizable associations between various operations management practices and performance outcomes. Then, this is applied to dynamic humanitarian logistics settings, exploring how practitioners perceive practice and performance, and how this is reported and documented for organizational performance improvement. A cumulative case study provides actionable recommendations for humanitarian practitioners and insights into an understudied area of performance management and organizational learning, which are then examined in-depth in a humanitarian field exercise. This dissertation demonstrates the importance of deliberate resource alignment, collaboration and learning for lasting logistics operations management success
