One particular type, the Personal Solicitation E-mail (PSE) mimics personal letters—modern perversions of ars dictaminis (the classical art of letter writing). In this article, I determine and discuss 19 appeals common to the PSE. These appeals were established first by conducting generative rhetorical analysis, then by volunteer coding, on 170 e-mails collected over a 12-month period. After defining these categories, I show how these letters are excellent twenty-first century teaching tools for pathos-based argumentation, logical appeals, the creation of ethos, and kairos in the development of perceived exigency. http://tc.eserver.org/30687.html http://tc.eserver.org/30687.html Arguments manifest in scientific visuals through graphic representation, content placement, and overall document structure. These arguments, designed to influence public perception, change over time in relation to sociopolitical climate. Analysis of a series of documents constructed deliberately to influence perception can help to determine patterns of argumentation and perceived exigencies. In this article, four self-guided tour brochures produced for distribution to visitors to the Glen Canyon Dam in 1977, 1984, 1990, and 1993 are analyzed in order to identify rhetorical strategies designed to influence public perceptions of the dam site, and examine how public perception of the dam, and related argumentation, is structured by sociopolitical climate.
