1. Graham, Elizabeth E. Host plant relationships and chemical communication in the cerambycidae.

Degree: PhD, 0324, 2010, University of Illinois – Urbana-Champaign

The beetle family Cerambycidae is one of the largest groups of insects. Commonly referred to as longhorned beetles, the larvae of cerambycids usually feed on the tissues of woody plants and can be important insect pests, damaging and even killing trees in managed and natural landscapes. In this dissertation, I revise a historical database on associations between the adult beetles and the plant species whose flowers they visited, and determine that beetles were commonly found on plants in the Asteraceae. However, the umbellifer Pastinaca sativa L. and the rose Aruncus dioicus (Walter) Fernald var. vulgaris (Maxim) were visited by the greatest number of beetle species. I conducted an experiment to explore the relationship between environmental stress of woody host plants and susceptibility to attack by cerambycid beetles, and found that the number of beetles completing development was positively associated with growth rate of the larval host tree. I also studied cross-attraction between beetles of different species and discovered that live male beetles in traps produced an aggregation pheromone that attracted adults of both sexes of a different cerambycid species. Finally, I conducted a field study that showed that the efficiency with which pheromone traps captured cerambycid beetles was greatly improved by treating trap surfaces with the polymer Fluon??. This information can be applied to improve methods for determining the geographic distribution and local abundance of species. Advisors/Committee Members: Hanks, Lawrence M.

2. Davis, Edward Rock. The PISA Phenomenon: Analysis of its Ascendancy in Media, Policymaker and Academic Discourses in Education .

Degree: University of Sydney

Since its initiation in 2000, the OECD Programme for International Student Assessment known as PISA has generated considerable attention in the media and public discussions, becoming an important international educational phenomenon. Much of the initial research into PISA focused on the performance of successful nations, including Finland and certain Asian countries, and analysed why these nations outperformed other countries. Countries which participated in PISA also conducted research on their national results. Limited research has examined the discourses surrounding PISA and discourse has tended to be analysed only at the national level. Few studies have compared PISA related discourse internationally or from a longitudinal perspective. This thesis used a range of methods to examine the discourses related to PISA over 15 years, at both an international comparative level, including Japan and South Korea with improving PISA performance and Finland and Australia with deteriorating PISA performance, and also at an Australian domestic level using both media discourse analyses and interview surveys of 30 education policymakers and academic researchers. Media discourse analysis was used to consider orientations in educational discourse in three ways: first, by examining the role of PISA in cross-national policy attraction and borrowing; second, by considering international discourses of ‘competition’; and third, by analysis of the depth and orientation of PISA media discourse on Australian Indigenous PISA performance. To complement the media analysis, senior Australian education policymakers and academic researchers were interviewed on their perspectives on the impact of PISA on Australian educational policy and research from 2000 to 2015. In relation to the international comparative discourse, the study showed a dominant discourse reflecting international attraction to Finnish educational culture which focuses on aspects of educational culture beyond what is measured in PISA. This discourse flourishes despite Finland’s strong but deteriorating performance in PISA. Analysis highlighted how some countries with improving performance (Japan and South Korea) had outward looking discourse with much cross-national attraction evident, while others with deteriorating performance (Australia and Finland) had a stronger inward, domestic focus. The competitive nature of PISA discourse led to analysis examining how this was reflected in different countries. Educational competitiveness and economic competitiveness are strong discourses in Japan and South Korea, while in Australia and Finland the focus is only on educational competitiveness, again reflecting the outward and inward looking trends. In relation to Australia’s discourse on PISA, although the large gap between Indigenous and non-Indigenous performance is perhaps the most outstanding feature of Australia’s PISA data, the analysis showed bias with a continued lack of media reporting on this issue and commensurate dearth of research attention. Interview data…
