The rapid development of climate policies and the need to understand the dynamics of climate change have highlighted and shaped the role of land use, land-use change and forestry dynamics (LULUCF), making it an issue of global importance. As a consequence, LULUCF has become a central topic in economic theory and in environmental sciences. The attention is focused on creating and expanding compr...

This paper explores how the dynamics of complex biological processes can be modeled as an organisation of multiple agents. This modelling perspective identifies organisational structure occurring in complex decentralised processes and handles complexity of the analysis of the dynamics by structuring these dynamics according to an organisational structure. More specifically, dynamic properties a...

Despite offering several promising concepts, the Language/Action Perspective (LAP) is still not in the mainstream of Information Systems Development (ISD). With use of a comparative evaluation of LAP theory and DEMO theory, the implication of DEMO’s reflection upon LAP is determined. The paper concludes by outlining an agenda for further research if LAP is to improve its footprint in the field.

Through the Blueprints for Violence Prevention Initiative, OJJDP provides information to communities on a broad array of violence prevention and intervention programs that have been proven to be effective. This Bulletin describes the demanding criteria established by the Center for the Study and Prevention of Violence to designate model Blueprints programs and the activities of the 11 programs ...

In this special section we report on the workshop Standards in Emotion Modeling held in August 2011, Leiden, The Netherlands. An important goal of this workshop was to identify challenges related to the development and evaluation of computational models of affective processes. These challenges were approached from a psychological and a computational modeling perspective. In this introduction we...

A growing number of collaborative networked organizations can be found in industry, services, and research. However, the lack of a reference model that could synthesize and formalize the base concepts, principles, and recommended practices, is an obstacle for an easier and more consistent development of the area. Therefore a reference modeling approach is proposed considering multiple modeling ...

Communicative action concerns achieving and maintaining mutual understanding among all those who are involved in a coordinated (organizational) situation. Communicative action is embedded in a social context. Current approaches in the Language/Action Perspective have focused mainly on the dynamic aspect of language, that is, on (business) conversation. In this paper, we develop a new model of c...

We propose a real-time and accurate solution to the Perspective-n-Point (PnP) problem –estimating the pose of a calibrated camera from n 3D-to-2D point correspondences– that exploits the fact that in practice the 2D position of not all 2D features is estimated with the same accuracy. Assuming a model of such feature uncertainties is known in advance, we reformulate the PnP problem as a maximum ...

A Data Warehouse (DW) is a data repository that integrates data from multiple sources and organizes the data according to a set of data structures called dimensions. Each dimension provides a perspective upon which the data can be viewed. In order to support an efficient processing of queries, a dimension is usually required to satisfy different classes of integrity constraints. In this paper, ...
