How Similarity Shapes Diagrams

Most diagrams communicate effectively despite the fact that diagrams as a group have a minium of conventions and a high tolerance for novelty. This paper proposes that the diversity and felicity of diagrammatic representation is based on three kinds of similarity between semantic propositions and spatial representations that allow people to interpret diagrams consistently with a minimum of effo...

In the absence of salient alternatives, a longer nonconsumption period results in stronger desire for the unconsumed good. However, in the presence of salient alternatives, ind...

Simulation of Climatic Conditions within the Caves Through a Controlled Laboratory Environment to Estimate the Annual Dissolution Rate of Karstic Shapes Inside Katale Khor and Saholan Caves

Aims & Backgrounds: Katlekhour Cave near Garmab (Zanjan) and Saholan Cave in southeast Mahabad, two Iranian tourist caves, attract a large number of tourists annually. Indiscriminate entry and higher number of tourists into the fragile and sensitive environment of the caves increase the concentration of carbon dioxide and disturb the chemical equilibrium inside the cave and it also has devastat...
