Many dune fields exhibit a downwind transition from forward-pointing barchan dunes to stabilized, backward-pointing parabolic dunes, accompanied by an increase in vegetation. A recent model predicts this pattern transition occurs when dune surface erosion/deposition rates decrease below a threshold of half the vegetation growth rate. We provide a direct test using a unique data set of repeat to...

Computer-assisted qualitative data analysis software (CAQDAS) is a well-known acronym in qualitative research. Nowadays, qualitative researchers are inclined to apply such software for various purposes. Critiques of the use of CAQDAS in qualitative research focus on the term “analysis”, claiming that that the tool does little to analyze data. According to these critiques, some users of CAQDAS a...

Use of the grounded theory research method (GTM) is increasing across many fields of inquiry. Understanding the GTM and how to apply it is therefore a key task for researchers examining the possibility of using this method in their research. Since its introduction by Glaser and Strauss in 1967, GTM has evolved into two major streams, and there has been a continual debate about the choice betwee...

Since the 1940s it has been proposed that landscape dissection into distinct valleys is limited by a threshold of channelization that sets a finite scale to the landscape. This threshold is equal to the hillslope length that is just shorter than that necessary to support a channel head. A field study supports this hypothesis by showing that an empirically defined topographic threshold associate...
