The urgency to preserve tropical forest remnants has encouraged the development of remote sensing tools and techniques monitor diverse attributes for management conservation. State-of-the-art methodologies mapping tracking these usually achieve accuracies greater than 0.8 cover monitoring; r-square values ~0.5–0.7 plant diversity, vegetation structure, functional trait mapping, overall ~0.8 cat...

The potential of agent-based modeling (ABM) has been demonstrated in various research fields. However, three major concerns limit the full exploitation of ABM; (i) agents are too simple and behave unrealistically without any empirical basis, (ii) 'proof of concept' applications are too theoretical and (iii) too much value placed on operational validity instead of conceptual validity. This paper...

We compare and critique two measures of risk perception. We suggest that a single question — “How risky is the situation?” — captures the concept of risk perception more accurately than the multiple-item measure used by Sitkin and Weingart (1995). In fact, this latter measure inadvertently captures notions of attractiveness or expected return, rather than risk perception. We further propose tha...

The study of human variation is central to both social and biomedical sciences, but social and biomedical scientists diverge in how variation is theorized and operationalized. Race is especially problematic because it is a cultural concept that contains implicit and explicit understandings of how collective bodies differ. In this article, we propose an operationalization of race that addresses ...

The objective of this technical report is twofold. It gives an introduction to the notions and operationalization of time and temporal data in the context of data modeling and databases. The more philosophical aspects and conceptions of time is not discussed herein. Secondly, we introduce the previously presented time and temporal concepts in the realm of Geographic Information Systems (GIS), o...

This work is focused on norm operationalization in aviation domain. The investigated paradigm can be described as: from legal norms to technical rules in the artifact. Normative requirements (norms) for the aircraft trajectories are extracted from the flight rules and airport procedures, and operationalized in a decision support system (DSS). The decision support is based on evaluation of risk ...
