Analysis of the context dependency of CODASYL find-statements with application to a database program conversion

AbstractMicrobes form multispecies communities that play essential roles in our environment and health. Not surprisingly, there is an increasing need for understanding if certain invader species will modify a given microbial community, producing either a desired or undesired change in the observed collection of resident species. However, the complex interactions that species can establish between each other and the diverse external factors underlying their dynamics have made constructing such understanding context-specific. Here we integrate tractable theoretical systems with tractable experimental systems to find general conditions under which non-resident species can change the collection of resident communities—game-changing species. We show that non-resident colonizers are more likely to be game-changers than transients, whereas game-changers are more likely to suppress than to promote resident species. Importantly, we find general heuristic rules for game-changers under controlled environments by integrating mutual invasibility theory with in vitro experimental systems, and general heuristic rules under changing environments by integrating structuralist theory with in vivo experimental systems. Despite the strong context-dependency of microbial communities, our work shows that under an appropriate integration of tractable theoretical and experimental systems, it is possible to unveil regularities that can then be potentially extended to understand the behavior of complex natural communities.

Parody as hybridic text: research report Parody can be seen as one of the techniques of selfreferentiality through which a consciousness of the context dependency of meaning is revealed in an aesthetic way. This article explores the theoretical background of parody as literary style against which the researcher challenged a group of teacher education students in a research programme to generate their own parodies. The task required that they choose a well-known fairy tale and use its structure to mock their own society. Students of another group were asked as the writers’ peers to read the stories in order to engage in a dialogue between encoder and decoder in the process of reception. The educational aim of the programme was to equip students to reflect critically and react creatively to social, political and economic issues that surround them. Furthermore, the researcher wanted to discover how these texts would generate a flexibility, fluency and hybridity in relationship with the students’ cultural identity and how they would project their own liminality in a no-man’s land between youth and adulthood. Analysis and interpretation of the parody texts revealed themes of late capitalism, materialism and consumerism, as well as typical student cultural manifestations of language usage and some of their existing attitudes toward the South African political society in post-apartheid. The students’ parodies have intertextual density with imitation and subversion of the original text contexts and values. The writers used a variety of stylistic techniques to generate double-voiced narratives as manifestation of literary creativity.
