The paper contains a new prof for the sufficiency in Joel H. Shapiro’s recent characterization of inner functions saying that an analytic selfmap φ of the open unit disk is an inner function if and only if the essential norm of the composition operator of symbol φ is equal to √ 1+|φ(0)| 1−|φ(0)| . The main ingredient in the proof is a formula for the essential norm of a composition operator in ...

To understand what it means to design ‘persuasive technology’, one probably needs to understand it in relation to design in general. Using examples from a variety of areas of design discourse, the first part of the paper presents the idea that design is inherently persuasive. Following a discussion of what this might imply to the identification of ‘persuasive design’ as an emerging research are...

An assessment of Herman and Chomsky’s 1988 five-filter propaganda model suggests it is mainly valuable for identifying areas in which researchers should look for evidence of collaboration (whether intentional or otherwise) between mainstream media and the propaganda aims of the ruling establishment. The model does not identify methodologies for determining the relative weight of independent fil...

During the War of Resistance against Japan (1937–1945), children were a major subject of propaganda images. Children had become significant figures in China when May Fourth intellectuals, influenced by evolutionary thinking, deemed “the child” as a central figure for the modernization of the country. Consequently, during the war, cartoonists employed alreadyestablished representations of childr...

The Janzen-Connell hypothesis proposes that plant interactions with host-specific antagonists can impair the fitness of locally abundant species and thereby facilitate coexistence. However, insects and pathogens that associate with multiple hosts may mediate exclusion rather than coexistence. We employ a simulation model to examine the effect of enemy host breadth on plant species richness and ...
