The importance of scale to the psychology of space (perception, thinking, memory, behavior) is discussed. It is maintained that scale has an important influence on how humans treat spatial information and that several qualitatively distinct scale classes of space exist. Past systems of classification are reviewed and some novel terms and distinctions are introduced. Empirical evidence for the n...

The goal of this study is to improve our understanding of the interactive function of impervious and vegetation covers at different levels of the local and intra-urban spatial scales in relation to air temperatures in an urban environment. A multiple regression model was developed using impervious and vegetation fractions at different scales to predict maximum air temperature for the entire Pho...

Bifacial PV modules and systems deliver more energy than equivalent monofacial modules in the same orientation. However, bifacial performance models are not yet mature enough to predict bifacial gains for all system configurations. Field performance data is needed at a variety of different spatial scales in order to improve and validate these models. This paper reports on a number of bifacial f...

This chapter discusses an innovative approach to educational broadcasting developed in post-apartheid South Africa, in a broader context of media globalization, international policy transfer, and socio-economic and cultural transformation. I argue that the reorganization of the spatial scales at which media economies and regulatory regimes operate requires the rethinking of established understa...

We derive a physiologically structured multiscale model for biofilm development. The model has components on two spatial scales, which induce different time scales into the problem. The macroscopic behavior of the system is modeled using growth-induced flow in a domain with a moving boundary. Cell-level processes are incorporated into the model using a so-called physiologically structured varia...

Understanding scale is fundamental in science education, but scale comprehension is difficult. One reason difficulties may arise is a disconnect between the linear scale of magnitude and how scale information is cognitively represented. An intervention was designed to foster a linear representation of magnitude, based on the theory that people represent magnitude information in a hierarchically...

ÐThis paper deals with a novel way for representing and computing image features encapsulated within different regions of scale-space. Employing a thermodynamical model for scale-space generation, the method derives features as those corresponding to ªentropy richº image regions where, within a given range of spatial scales, the entropy gradient remains constant. Different types of image featur...
