Glucose modulates event-related potential components of recollection and familiarity in healthy adolescents.
Full text linkIntroduction Behavioural evidence supports the notion that oral glucose ingestion enhances recognition memory judgements based on recollection, but not familiarity. The present study sought to clarify and extend upon these behavioural findings by investigating the influence of glucose administration on event-related potential (ERP) components that are thought to be differentially mediated by recollection and familiarity processes in healthy adolescents. Methods In a within-subjects design, participants performed a recognition memory task, during which time electroencephalogram (EEG) was recorded, subsequent to ingestion of either (a) glucose or (b) placebo in a counterbalanced order. Results Response times during the recognition memory task were observed to be faster for the glucose condition, relative to a placebo control. Further, glucose ingestion was associated with an enhanced left parietal old/new ERP effect (a marker of recollection) and an enhanced mid-frontal old/new ERP effect (known to be mediated by familiarity). Discussion These findings (a) support the results of previous research that the ‘glucose memory facilitation effect’ can be extended to healthy adolescents, but (b) suggest that glucose enhances both the recollection and familiarity components of recognition memory. The observed ERP profile has important implications for the proposal that glucose specifically targets the hippocampus in modulating cognitive performance
Portfolio of recorded performances and exegesis: Messiaen’s musical language for the jazz pianist - an exploration through performance.
Full text linkMoving beyond Gunther Schuller’s Third Stream amalgamation of classical and jazz, this study explores whether the musical language of Olivier Messiaen can make a valid contribution to jazz piano performance. Initially, my project sought to answer such questions as: What elements of the musical language of Messiaen already exist in the jazz vocabulary? Am I able to extend this further? What are the timbral structures and pianistic effects within Messiaen’s musical language? What will be the most effective application of Messiaen’s musical language to jazz piano performance? Endeavouring to answer the final question led me to consider such aspects as whether the project should be limited to quoting Messiaen motifs, arranging Messiaen melodies, replacing jazz harmonic structures on standards with examples from Messiaen’s musical language or whether it would be better to approach the research conceptually. The work of Hubert Nuss provided encouraging reassurance that this was not an impossible task. In order to articulate this conception, the initial challenge was to decide how the classical and jazz worlds might meet in a ‘Messiaen’ technique. The approach adopted was similar to that used for undergraduate jazz study, namely, immersion in the piano scores and recordings of Messiaen’s music as well as by live performances. This was followed by the development and assessment of a contrived approach when specific techniques, such as tonal colourings or harmonic structures, were developed through prepared exercises and consciously included in my performance. It was then compared with an intuitive approach when no such precise parameters were established. This submission consists of CD recordings of two public recitals and an exegesis. It documents the development of this Messiaen technique and discusses its application in my performances. It also demonstrates the ways that Messiaen’s musical language can be used within jazz piano performance to provide a colour that distinguishes jazz piano performance in a competitive field.Thesis (M.Mus.) -- University of Adelaide, Elder Conservatorium of Music, 201
Understanding the text of teaching: Complexities of comprehension
Full text linkLearning to teach and learning to read have some similarities in the way the learning is enacted. Drawing on narratives constructed from semi-structured interviews with four Graduate Diploma of Education Primary pre-service teachers, a conceptual framework was developed. The framework included personal history, the technical skills of teaching, social aspects and reflection, to help shape a reading of the 'text' of teacher education. This reading revealed that, in this small group of pre-service teachers, reading the text was informed by what was happening in their lives, their personal history and their dispositions towards learning
The Scientific romances of Charles Howard Hinton : the fourth dimension as hyperspace, hyperrealism and protomodernism
Full text linkThis thesis examines the epistemological, socio-cultural and aesthetic impact of the hyperspace philosophy of Charles Howard Hinton, as expressed within his two-volume
collection of Scientific Romances (1884-1896). Hinton's hyperspace philosophy is founded on the belief that the fourth dimension exists as a transcendental yet material
space that is accessible to both the mind and the physical senses. Inspired by Immanuel Kant's discussion of space as an a priori intuition, Hinton's project is one of
consciousness expansion: he argues that 'a new era of thought' can be attained through the recognition of the fourth dimension. The thesis demonstrates that, in the Scientific Romances, Hinton seeks to engender the 'reality' of the fourth dimension within the reader's imagination through the collaboration of reader and author. Hinton's hyperspace philosophy is thus concerned with mediation, the ways in which the consciousness thinks and creates with and through the aesthetics of space. In addition to providing the most developed analysis of Hinton's writing to date, this thesis examines the work of Hinton's contemporaries
exploring the ways in which the discourse of the fourth dimension can offer new readings of familiar literary texts. A recurring explanatory device throughout
hyperspace philosophy is the dimensional analogy, and the thesis illustrates how this trope resonates across the work of contemporary writers including Lewis Carroll, H. G. Wells, HenryJames, Friedrich Nietzsche and William James

An instructional design framework for authentic learning environments
Full text linkThe instructional technology community is in the midst of a philosophical shift from a behaviorist to a constructivist framework, a move that may begin to address the growing rift between formal school learning and real-life learning. One theory of learning that has the capacity to promote authentic learning is that of situated learning. The purpose of this three part study was firstly, to identify critical characteristics of a situated learning environment from the extensive literature base on the subject; secondly, to operationalise the critical characteristics of a situated learning environment by designing a multimedia program which incorporated the identified characteristics; and thirdly, to investigate students’ perceptions of their experiences using an multimedia package based on a situated learning framework. The learning environment comprised a multimedia program for preservice teachers on assessment in mathematics, together with recommended implementation conditions in the classroom. Eight students were observed and interviewed to explore their perceptions of the situated learning environment. Findings suggest that the use of the situated learning framework appeared to provide effective instructional design guidelines for the design of an environment for the acquisition of advanced knowledge

The films of Chantal Akerman : a cinema of displacements
Full text linkThis thesis attempts to broaden the critical boundaries within which the films of
Chantal Akerman have been discussed. First, it extends analysis from Akerman's
70s to her 80s and 90s films. Second, it argues that as well as her gender and
aesthetic identities, Akerman's Belgian and Jewish identities should be
acknowledged. Finally, it suggests that each of these four identities: woman,
independent film-maker, Belgian and Jewish allow her a position of marginality,
figured in her films through the trope of 'displacement'.
The structure of the thesis is two-fold: it extends discussion of Akerman's cinema to
films not previously considered, and through this extension engages with
contemporary issues in film and cultural theory such as female authorship,
independent and national, and marginal cinemas. Chapter one `Woman' and chapter
two `Independent' extend the reading of gender and sexuality and formal and
aesthetic innovation in Akerman's cinema. In the first chapter this is done through
consideration of the films Golden Eighties (1986) and Nuit et jour (1990), while in
the second her short films, video work and work for television are examined.
My third and fourth chapters offer areas of Akerman's work which have not
previously been studied. Chapter three, `Belgian', considers the significance of
Akerman's nationality for her film-making while engaging with theories around
national cinema. It examines the possibility of a `Belgian national cinema' and the
intersections which arise between this and Akerman's cinema, especially around
Toute une nuit (1982). Finally, in my fourth chapter, `Jewish', I use Histoires
d'Amerigue (1989) and D'Est (1993) to argue that Akerman's is a `wandering'
cinema, in which she is constantly examining the homelessness and displacement
that her Jewishness engenders
Effects of EMFs from Undersea Power Cables on Elasmobranchs and Other Marine Species.
Full text linkAnthropogenic electromagnetic fields (EMFs) have been introduced into the marine environmentaround the world and from a wide variety of sources for well over a century. Despite this, littleis known about potential ecological impacts from EMFs. For decades, power transmissioncables have been installed across bays and river mouths, and connecting near-shore islands to themainland, with little consideration of possible effects to marine species from EMFs. At a time ofgreater environmental awareness, the US now faces the possibility of a new source of EMFs overa much greater extent of the seabed from offshore renewable energy facilities in coastal waters.This literature review synthesizes information on the types of power cables and models theexpected EMFs from representative cables. Available information on electro- and magnetosensitivityof marine organisms, including elasmobranchs (sharks and rays) and other fishspecies, marine mammals, sea turtles, and invertebrates is summarized and used in conjunctionwith the power cable modeling results to evaluate the level of confidence the existing state ofknowledge provides for impact assessment. Gaps in our knowledge of power cablecharacteristics and the biology needed to understand and predict impacts are summarized andform the basis of recommendations for future research priorities. Potential mitigationopportunities are described with a discussion of their potential secondary impacts as well assuggested methods for monitoring mitigation effectiveness. Finally, because interest in offshorerenewable energy has increased throughout US coastal waters, there is a concern that organismscould be exposed to multiple seabed power cables. Cumulative effects of this exposure are discussed
Wordsworth and death
No full textWordsworth is known as the poet of joy and hope, and to associate his name with death may seem at first strange. Yet, according to his own estimation, he was the poet not simply of joy but of “the very heart of man," of "human kind, and what we are”, of "men as they are men within themselves." Any vision of human nature which does not take into account the facts of mortality and bereavement is blinkered and inevitably inadequate and Wordsworth was committed to clarity of perception and the fullest insights of the Imagination. He did not shy away from the implications of “our mortal Nature”; throughout his career, he sought to portray in poetry the place of death in human life.
Two basic ways of understanding mortality are considered in this thesis: the first is death as disjunction, extinction, the end; the second is death as part of a larger continuity, a threshold, a stage. The conflict between these two visions was fundamental to Wordsworth's thought, and writing. Isolation and despair were the corollaries of the first vision, while the capacity for love and hope which was essential to the life of the human spirit was nurtured and made possible by the second. Wordsworth wrestled in his writings with the effects of these different visions of death on the complexities of human nature.
The thesis has been divided into three main parts. Section I - Death in Wordsworth's Time - seeks to place the poet into a historical context. Section II - Death in Wordsworth' Life - is concerned with Wordsworth's personal experiences of loss and feelings about his own mortality, And in Section III - Death in Wordsworth's Poetry - what he had to say about death is considered in relation to some of the other major themes in his poetry
