The discourse of biology lectures : aspects of its mode and text structure

The present thesis investigates mode related aspects in biology lecture discourse and attempts to identify the position of this variety along the spontaneous spoken versus planned written language continuum. Nine lectures (of 43,000 words) consisting of three sets of three lectures each, given by the three lecturers at Aston University, make up the corpus. The indeterminacy of the results obtained from the investigation of grammatical complexity as measured in subordination motivates the need to take the analysis beyond sentence level to the study of mode related aspects in the use of sentence-initial connectives, sub-topic shifting and paraphrase. It is found that biology lecture discourse combines features typical of speech and writing at sentence as well as discourse level: thus, subordination is more used than co-ordination, but one degree complexity sentence is favoured; some sentence initial connectives are only found in uses typical of spoken language but sub-topic shift signalling (generally introduced by a connective) typical of planned written language is a major feature of the lectures; syntactic and lexical revision and repetition, interrupted structures are found in the sub-topic shift signalling utterance and paraphrase, but the text is also amenable to analysis into sentence like units. On the other hand, it is also found that: (1) while there are some differences in the use of a given feature, inter-speaker variation is on the whole not significant; (2) mode related aspects are often motivated by the didactic function of the variety; and (3) the structuring of the text follows a sequencing whose boundaries are marked by sub-topic shifting and the summary paraphrase. This study enables us to draw four theoretical conclusions: (1) mode related aspects cannot be approached as a simple dichotomy since a combination of aspects of both speech and writing are found in a given feature. It is necessary to go to the level of textual features to identify mode related aspects; (2) homogeneity is dominant in this sample of lectures which suggests that there is a high level of standardization in this variety; (3) the didactic function of the variety is manifested in some mode related aspects; (4) the features studied play a role in the structuring of the text.

Closing Pandora's box: a defence of Alvin Plantinga's epistemology of religious belief

I argue (1) that Alvin Plantinga’s theory of warrant is plausible and (2) that, contrary to the Pandora’s Box objection, there are certain serious world religions that cannot successfully use Plantinga’s epistemology to demonstrate that their beliefs could be warranted in the same way that Christian belief can be warranted. In arguing for (1), I deploy Ernest Sosa’s Swampman case to show that Plantinga’s proper function condition is a necessary condition for warrant. I then engage three objections to Plantinga’s theory of warrant, each of which attempts to demonstrate that his conditions for warrant are neither necessary nor sufficient. Having defended the plausibility of Plantinga’s theory of warrant, I present and expand his key arguments to the effect that naturalism cannot make use of it. These arguments provide the conceptual tools that are needed to argue for (2): that there are certain world religions that cannot legitimately use Plantinga’s theory of warrant to demonstrate that their beliefs could be warranted in the same way that Christian belief can be warranted.

Comparison of biology between Helicoverpa zea and Helicoverpa armigera (Lepidoptera: Noctuidae) reared on artificial diets.

The objective of this study was to compare growth and development of Helicoverpa zea Boddie and Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) larvae that were feeding on an artificial diet. Neonate larvae of H. zea and H. armigera were collected in maize fields cultivated at the Brazilian Agricultural Research Corporation, Embrapa Maize & Sorghum, in Sete Lagoas (Minas Gerais) and in farmers? cotton fields in Luís Eduardo Magalhães (Bahia), respectively. Bioassays were conducted in the laboratory using individual larvae in 50 mL plastic cups fed a white bean?based artificial diet and maintained at a temperature of 26 ± 2 °C and a relative humidity of 47 ± 10%. The following larval biological parameters were evaluated: number and duration of instars, survival of larval instars and pupae, larval biomass, larval head capsule size, and larval length. An adaptation index was computed for comparison of development of the 2 species. Significant differences were observed between the species for all variables except for the number of instars and pupal survival. Although H. armigera larvae developed faster and were smaller than H. zea larvae, the diet tested can be considered adequate for rearing both species in the laboratory.
