qualitative data to construct theories ‘grounded’ in the data themselves...” (Charmaz 2006, p.2). According to Glaser and Strauss (1967) Grounded Theory Methods (GTM) represent a rigorous set of practices for exploring a new domain or a domain which lacks a dominant theory. However, Grounded Theory (GT) is not just a set of procedures to be followed in a study, but an approach which supports th...

In experience-based (or case-based) reasoning, new problems are solved by retrieving and adapting the solutions to similar problems encountered in the past. An important issue in experience-based reasoning is to identify diierent types of knowledge and reasoning useful for diierent classes of case-adaptation tasks. In this paper, we examine a class of non-routine case-adaptation tasks that invo...

Shear has been known to exist for many years in the topographic structure of the primary visual cortex, but has received little attention in the modeling literature. Although the topographic map of V1 is largely conformal (i.e. zero shear), several groups have observed topographic shear in the region of the V1/V2 border. Furthermore, shear has also been revealed by anisotropy of cortical magnif...

The diversity of organisms and complexity of ecosystems prevent through inventory and monitoring of protected areas, yet sound databases are needed to manage ecosystems for long-term persistence. One strategy is therefore to focus monitoring on indicator organisms, but guidelines are lacking for selecting appropriate species or groups. This paper presents a simple protocol based on ordination t...

Abstract. We examine the influence of incision thresholds on topographic and scaling properties landscapes that follow a landscape evolution model (LEM) with terms for stream-power incision, linear diffusion, uniform uplift. Our analysis uses three main tools. First, we graphical behavior theoretical relationships between curvature steepness index (which depends drainage area slope). These plot...
