A persuasão em trabalhos de conclusão de curso do bacharelado em Geologia

Abstract

Resumo: O objetivo deste trabalho é indagar sobre a presença de elementos persuasivos em trabalhos de conclusão de curso do Bachar universidade pública argentina, a fim de determinar que papel é exercido pela argumentação retórica nestes escritos, considerando a classificação proposta por Padilla, Douglas e Lopez (2011) sobre as possibilidades de argumentação (demonstrativa, retórica e dialética). Para cumprir nosso propósito, utilizamos a classificação de recursos de impessoalidade e de personalização de García Negroni (2008) e a de "outros elementos de relação" de Hyland (2000), e contabilizamos em nosso corpus a presença de todos estes elementos, oferecendo, também, exemplos ilustrativos de cada categoria. Palavras-chave: Argumentação. Persuasão. Trabalho de conclusão de curso. Abstract:The main objective of this paper is to inquire abou persuasive elements in undergraduate final theses of Geology, in order to examine the role that rhetorical argumentation plays in these writing. To do so, I drew upon the scheme proposed by Padilla, Douglas and Lopez (2011) about academic argumentation, which includes the demonstrative, the rhetoric and the dialectical modes; the categorization about impersonalization and personalization resources proposed by García Negroni (2008);and Hyland's (2000) classification about "other relational markers". I have counted the incidence of these discursive elements in the corpus, offering illustrative examples of each category.

Comparative morphology of the oropharyngeal denticles in the order Rhinopristiformes and its functional implications (Chondrichthyes: Batoidea)

“…The oropharyngeal denticles morphology observed in Z. brevirostris is similar to that previously described in the literature (Rangel et al, 2016; Rangel, 2015), except for the number of cusps. Lateral distal projections of denticles were named as cusps herein in accordance with Cappetta (2012), differing from the works of Rangel (2015) and Rangel et al (2016).…”

“…All specimens examined in the present study had denticles in their oropharyngeal region, from the region closest to the mouth to the region immediately anterior to the esophagus. The presence of denticles in the oropharyngeal region seems to be exclusive for Rhinopristiformes within Batoidea, considering the available literature (Atkinson & Collin, 2012; Deynat, 2005; Rangel et al, 2016; Rangel, 2015), but their presence in potamotrygonines needs confirmation. Among the batoid taxa examined by Atkinson and Collin (2012), only guitarfishes presented oropharyngeal denticles, but no freshwater stingray was included.…”

“…The presence of keels on denticles could promote a decrease in hydrodynamic drag during the swimming of pelagic sharks (Atkinson & Collin, 2012; Mello et al, 2011; Raschi & Musick, 1984). In the same way, oropharyngeal denticles with keels could reduce the hydrodynamic drag in the pharyngeal tissue during the feeding and processing of prey (Rangel, 2015). On the other hand, denticles with no ornamentation may be ideal for protecting tissue against abrasion and damage caused by solid pieces of food (Atkinson & Collin, 2012; Raschi & Musick, 1984).…”

“…Nevertheless, given the low number of specimens examined, a larger sample size would be desirable to test these differences. When analyzing the images provided by Rangel (2015) and Rangel et al (2016), it is possible to notice that the dorsal surface of Z. brevirostris was not sampled in those works.…”

“…According to Atkinson and Collin (2012), these denticles are structures historically relevant for Chondrichthyes and, therefore, could be useful to identify species. Additionally, investigating the morphology of oropharyngeal denticles and their functional implications in the feeding and ventilation of batoids can provide data on the ecological and evolutionary aspects of such structures in Elasmobranchii (Rangel et al, 2016; Rangel, 2015).…”
