Although research and practice agree that visions are essential for organizations, the process of vision development remains elusive in academic literature. Presenting the “theory wave“, this paper proposes a knowledge-based theory for developing sustainable visions to guide the creation of measures and actions in the future. Central to the theory wave, we suggest three features that characteri...

An ordered labeled tree is a tree which nodes are labeled and in which the left-to-right order among siblings is significant. Given two ordered labeled trees P and T , the constrained tree inclusion problem is to determine whether it is possible to obtain P from T by deleting degree-one or degreetwo nodes. G. Valiente proposed a bottom up algorithm which solves the problem in O(|P ||T |) time a...

The visual system performs complicated operations such as visual grouping e*ciently on its natural input. To study this adaptation to natural stimuli we measure spatio-temporal interactions of orientations in scenes with natural temporal structure recorded using a camera mounted to a cat’s head. We -nd long range spatial and long lasting temporal correlations of orientations with collinear inte...

In this article, we propose a new ontology evolution approach that combines a top-down and a bottom-up approach. This means that the manual request for changes (top-down) by the ontology engineer is complemented with an automatic change detection mechanism (bottom-up). The approach is based on keeping track of the different versions of ontology concepts throughout their lifetime (called virtual...

The article discusses several issues relevant for the annotation of written and spoken corpus data with information structure. We discuss ways to identify focus top-down (via Questions under Discussion) or bottom-up (starting from pitch accents). We introduce a two-dimensional labelling scheme for information status and propose a way to distinguish between contrastive and noncontrastive informa...

This paper aims to shed some light on the difficulties we face in constructing a generally acceptable normative framework for thinking about public health. It argues that there are three factors which combine to make theorising about public health difficult, and which when taken together defeat simplistic top-down and

The transformation of the US Army to the Objective Force will rely heavily upon the use of modeling and simulation (M&S) for analysis, including assessment of our ability to fight in urban environments. Current model research for military operations in urban terrain (MOUT) is disjoint. Current models are judged to be insufficient as a foundation for simulation of urban operations. The Army Mode...
