Temperature measurements with the relativistic Sunyaev-Zel’dovich effect
No full textAt temperatures above ∼5 keV, the non-relativistic approximation used to derive the classical thermal Sunyaev-Zel’dovich effect spectrum begins to fail. When relativistic effects are included, the spectrum becomes temperature-dependent. This leads to both a problem and an opportunity: a problem, because when the temperature dependence is not accounted for the Compton-y estimate is biased; and an opportunity, because it represents a new way to measure the temperature of the intracluster medium independently of X-ray observations. This work presents current results from investigating the impact of relativistic effects on Planck cluster observations, and projections for future measurements of cluster temperatures using the Atacama Large Aperture Sub-millimetre Telescope
Investigating the Source of Planck-Detected AME: High-Resolution Observations at 15 GHz
No full textThe Planck 28.5 GHz maps were searched for potential Anomalous Microwave Emission (AME) regions on the scale of ~3° or smaller, and several new regions of interest were selected. Ancillary data at both lower and higher frequencies were used to construct spectral energy distributions (SEDs), which seem to confirm an excess consistent with spinning dust models. Here we present higher resolution observations of two of these new regions with the Arcminute Microkelvin Imager Small Array (AMI SA) between 14 and 18 GHz to test for the presence of a compact (~10 arcmin or smaller) component. For AME-G107.1+5.2, dominated by the Hii region S140, we find evidence for the characteristic rising spectrum associated with either the spinning dust mechanism for AME or an ultra- /hypercompact Hii region across the AMI frequency band; however, for AME-G173.6+208 we find no evidence for AME on scales of ~2–10 arcmin
The language of risk and the risk of language
No full textThis mini-dissertation is written towards an MA in Linguistics. As such, it falls within the domain of Humanities. However, its author is a doctor and the subject matter is medical, which falls within the domain of Science. The mini-dissertation thus bridges these different domains, and the references and background reading as well as the application of the research reflect this hybrid nature. A glossary of medical terms and acronyms is thus given. In addition to being a doctor, the author is also a mother of two children. Thus the subject matter of pregnancy and its unknowns is close to her professional and personal realms of experience. For this reason, although the author has tried to be objective, she cannot pretend that true objectivity is always achieved
A statistical multiresolution approach for face recognition using structural hidden Markov models
No full textThis paper introduces a novel methodology that combines the multiresolution feature of the discrete wavelet transform (DWT) with the local interactions of the facial structures expressed through the structural hidden Markov model (SHMM). A range of wavelet filters such as Haar, biorthogonal 9/7, and Coiflet, as well as Gabor, have been implemented in order to search for the best performance. SHMMs perform a thorough probabilistic analysis of any sequential pattern by revealing both its inner and outer structures simultaneously. Unlike traditional HMMs, the SHMMs do not perform the state conditional independence of the visible observation sequence assumption. This is achieved via the concept of local structures introduced by the SHMMs. Therefore, the long-range dependency problem inherent to traditional HMMs has been drastically reduced. SHMMs have not previously been applied to the problem of face identification. The results reported in this application have shown that SHMM outperforms the traditional hidden Markov model with a 73% increase in accuracy
'Te Kawau Mārō' The Role of Media in Revitalising Te Reo Māori
No full textThe intent of this thesis is to investigate the role media plays in relation to the revitalisation of te reo Māori in Aotearoa/New Zealand society. This is essential as the media's latent potential is often underestimated and therefore underutilised.
For Māori and inevitably te reo Māori, media has been a topic of heated contestation for over a century. It is postulated that throughout this troubled history, media's influence has contributed to an erosion of te reo Māori and then conversely, since the late 20th century, its attempted revival. The journey of te reo Māori from past to present may be likened to a voyage of a traditional 'waka hourua' (voyaging or double hulled canoe). 'Nga ngaru e toru' ('three waves') illustrates the three stages that I have defined as catalysts significantly impacting te reo Māori.
Grounded firmly in a Kaupapa Māori methodological and theoretical framework based on careful research and intimate cultural knowledge, my innovative approaches to language revitalisation entitled the Tapatoru (triangle) Model 1 and Tapatoru Model 2 will be introduced and explained. These distinct language revitalisation paradigms illustrate the core ingredients needed in effective language revival and illustrate the positioning and function of the media within these strategic models
Experimental animation and the neosurrealist remediation of popular music video
No full textOnce appearing to function primarily as a commercial tool for popular entertainment, the popular form of music video has recently been exposed by scholars as formally and functionally diverse, with a rich history stretching back decades before the advent of MTV. Animated music videos owe much to centuries old traditions spanning the visual, musical and performing arts, providing performative and material models that inspire contemporary video directors. Experimental animation, surrealism and music video form a matrix of historical and contemporary significance; however, few scholars have undertaken close examinations of the relations between them. John Richardson and Mathias Korsgaard show how music video directors have employed surrealist compositional strategies together with experimental animation methods, thus giving rise to challenging new forms that traverse disparate approaches to art and culture. Building upon their contributions, this article explores the continuity between experimental animation, surrealism and music video, with a view to discovering the subversive potential of this matrix. In order to probe this potential, the author examines how music video directors experiment with animation technique as a means of subversion and enrichment of popular music video. Through close analysis of music videos directed by Adam Jones, Stephen Johnson, Floria Sigismondi and Chris Hopewell, this article charts the continuity of surrealist strategy across culturally specific moments in history, thus provoking questions around the perceived functions of animated media and popular music video
The New Zealand Wars Documentary Series: Discursive Struggle and Cultural Memory.
No full textThe 1998 television broadcast of The New Zealand Wars documentary series was a significant public event, which had a major impact on a broad range of communities and individuals in Aotearoa New Zealand. This popular television history engaged with issues of historical veracity, race, culture and nationhood and challenged previously dominant discourses associated with these concepts. In doing so, it provoked heated debate, and a re-imagining of 'nation', and also opened up spaces for alternative ways of engaging with historical narrative.
Informed by post-colonialism, cultural studies and cultural memory, this thesis explores the discursive and affective role of The New Zealand Wars, as it has operated within the turbulent climate of 1990s New Zealand cultural relations. This catalytic function is described in this thesis as a phenomenon of a television series shaped by, whilst also intervening in, processes of cultural colonisation and decolonisation.
While both of these processes involve the transmission of discourse via cultural forms, the act of cultural decolonisation requires, in addition, the convergence of a number of agents (people and communities, discursive and memory resources) and circumstances, within particular contextual conditions. Such a convergence provided the conditions for the discursive synthesis, which shaped the production, construction and reception of this series.
The role of audio-visual media (and specifically television documentary) in transmitting cultural memory is significant as it enables the flow of memory through channels or forms (such as visual, oral and aural traditions) that can bring about new perspectives and critical reflections upon colonial discourse and dominant concepts of nation and culture. In addition to these social and intellectual processes of audience engagement, this thesis argues that experiential and affective dimensions of cultural memory can (in these specific circumstances) open up radical spaces, offering the potential for generating awareness and sparking political action.
These issues are explored through a tripartite analysis of the production context, construction and reception of The New Zealand Wars series. The integration of these three phases of analysis has generated a number of insights into the potential of audio-visual forms, including their producers and audiences, to participate in the negotiation of, and resistance to, colonial discourse. Such insights serve to challenge taken-for-granted constructions of nation and history, and suggest the increasing relevance of alternative concepts such as community-building and cultural memory. Ultimately, this thesis argues that television documentary can serve as a prime site for the articulation of these concepts. The New Zealand Wars serves as a case study, which demonstrates both the potential of this site, and the significance of the social-historical and cultural context in framing this series
