Memorial service and poem Abstract: Rosine Guiterman was born Rosine Lion in London in 1886 and died in 1960. She gained her BA in Arts from Sydney University in 1908. In 1911 she gained her M.A. degree in English, having won the University gold medal for English verse. While at Sydney University, she helped establish the Sydney University Settlement. She went on to be a social activist in Sydney in the areas of pre-World War II refugee settlement, Aboriginal rights and world peace. She was well known in Sydney theater, both as an actor and director. Throughout her life she worked as a English and history teacher, and continued to write and broadcast on radio. Description: This anonymous roneo-ed document was apparently produced for a memorial service at the time of her death, both to document her life and to record tributes paid to her by those who knew her. Attached to the document is a poem she wrote in 1953 which represented an impassioned attack on the Sydney Morning Herald in reaction to the paper’s headline: "The execution of the Rosenbergs will end a two years' legal battle".The papers where kindly donated by (Dr) Ron Witton.

Allied health professionals (therapists), in the disability sector, work within government and funded or charitable non-government agencies, schools, communities, and private practice. This article reports the findings of a qualitative study of therapist workforce and service delivery in the disability sector in rural and remote New South Wales (NSW), Australia. The aim was to investigate issues of importance to policy-makers, managers and therapists providing services to people with disabilities in rural and remote areas. Methods: The project gathered information via semi-structured interviews with individuals and small groups. Head office and regional office policy-makers, along with managers and senior therapists in western NSW were invited to participate. Participants included 12 policy-makers, 28 managers and 10 senior therapists from NSW government agencies and non-government organisations (NGOs) involved in providing services and support to people with disabilities in the region. Information was synthesised prior to using constant comparative analysis within and across data sets to identify issues.Results: Five broad themes resonated across participants’ roles, locations and service settings: (1) challenges to implementing policy in rural and remote NSW; (2) the impact of geographic distribution of workforce and clients; (3) workforce issues - recruitment, support, workloads, retention; (4) equity and access issues for rural clients; and (5) the important role of the NGO sector in rural service delivery and support. Conclusions: Although commitment to providing best practice services was universal, policy-related information transfer between organisations and employees was inconsistent. Participants raised some workforce and service delivery issues that are similar to those reported in the rural health literature but rarely in the context of allied health and disability services. Relatively recent innovations such as therapy assistants, information technology, and trans-disciplinary approaches, were raised as important service delivery considerations within the region. These and other innovations were expected to extend the coverage provided by therapists. Nongovernment organisations played a significant role in service delivery and support in the region. Participants recognised the need for therapists working for different organisations, in rural areas, to collaborate both in terms of peer support and service delivery to clients.

This is due partly to the ignorance of modelers, and more to the ability of existing statistical tests to detect specification errors. In practice, models are often calibrated by minimizing the sum of squared difference between the modelled and actual observations. It is challenging to disentangle model error from estimation error in the residual series. To circumvent the difficulty, we study an alternative way of estimating the model by exact calibration. We argue that standard time series tests based on the exact approach can better reveal model misspecifications than the error minimizing approach. In the context of option pricing, we illustrate the usefulness of exact calibration in detecting model misspecification. Under heteroskedastic observation error structure, our simulation results shows that the Black-Scholes model calibrated by exact approach delivers more accurate hedging performance than that calibrated by error minimization.

It is upon this new approach to identifying and preventing ill health and disease that this working paper focuses. While the digital health approach to the body and health spans the arc from patient care to public health surveillance techniques, the discussion here largely is directed at the implications for the digital health ‘revolution’ in relation to the practice of health promotion; or what I refer to as ‘digitized health promotion’. It is argued that despite concerted efforts on the part of those advocating for a less individualistic approach to health promotion since the 1970s and drawing attention to the social determinants of health, digital health technologies as they are advocated for promoting health represent a renewed focus on personal responsibility for health. In the discourses and practices of digitized health promotion, health risks have become increasingly individualized and viewed as manageable and controllable as long as lay people adopt the appropriate technologies to engage in self-monitoring and self-care. With the advent of the big data produced by digital technologies and the use of sophisticated algorithms to manipulate these data, it has become ever more convenient to focus attention on personal responsibility for health states. The digitalized health promotion phenomenon, therefore, operates as one dimension of the progressive withdrawal of the state in many developed countries from attempting to challenge the social and economic factors causing ill health and disease and efforts to promote social justice.

As a result, proteins found in the centre of the lens (the nucleus) are present for a lifetime. This tissue can therefore be used to examine major posttranslational events that take place in long-lived proteins. Age-dependent deterioration of long-lived proteins in humans may have wide-ranging effects on health, fitness and diseases of the elderly [1]. To a large extent, denaturation of old proteins appears to result from the intrinsic instability of certain amino acids, however these reactions are incompletely understood. In this thesis, to understand more about these reactions, the breakdown of peptides was studied under controlled conditions, typically at physiologically relevant pHs and with elevated temperatures used to promote the reaction. Significant truncation of long-lived proteins has been shown to occur in the aged human lens. In the case of α-crystallin, one notable feature of the sequences of two of the most abundant truncations (αA 67-80 and αB 1-18) was that sites of cleavage were adjacent to Ser residues. While the truncation of proteins at Asp/Asn residues via the formation of a succinimide ring has been well characterised, our understanding of the processes that enable truncation at Ser is incomplete. The first part of this thesis aimed at understanding the mechanisms behind this truncation. A secondary aim was to understand the mechanism behind the age-related racemisation of Ser residues seen in the lens, and determine if it occurs via a mechanism analogous to that seen with Asp residues. Model peptides based on the sequence of known Ser truncation sites in human α-crystallin were exposed to elevated temperatures at physiological pH. Non-enzymatic truncation at the N-terminus of Ser, similar to that seen in the aged-lens was demonstrated. A range of additional factors were also examined for their ability to promote truncation. The role of the Ser hydroxyl group was investigated and found to play an important role in truncation at Ser. Interestingly Ser racemisation was also observed under these conditions, and it occurred regardless of the presence of a free or blocked Ser hydroxyl group. This was at odds with our initial hypothesis that both racemisation of Ser and truncation the N-terminal side of Ser might be a linked process, occurring via formation of a cyclic tetrahedral intermediate. Another possible source of Ser racemisation was investigated by examining the potential of phosphoser (pSer) residues to form dehydroalanine (DHA) via beta elimination. While DHA was generated from a model peptide at physiological pH, the results in this thesis did not find any evidence of water adding to the double bond, thus ruling it out as a possible explanation for Ser racemisation in the lens. However the observed formation of DHA at physiological pH does provide a potential explanation for the extensive non-covalent cross linking seen in aged lens proteins. The second part of this thesis examined a range of modifications that can occur at a peptide N-terminus. Approximately 70% of soluble proteins in eukaryotic cells have an acetylated α amino group. One proposed role of this is that it protects the protein from a range of N-terminal modifications. However following age-related internal truncations, such as those observed at the N-terminus of Ser and other known truncations, the resulting protein fragments (with free amino groups) could then be subject to N-terminal degradation. Using model peptides based on human lens crystallin sequences, facile racemisation of N-terminal residues incubated under physiological conditions was demonstrated. It was shown to occur across a range of N-terminal residues, buffers and temperatures. Unexpectedly the racemisation rate of L-residues was almost twice that of D-residues but the reasons for this are as yet unclear. A novel mechanism to explain these findings, involving the formation of a Schiff base has been proposed. Racemisation of the N-terminal residue was also shown to render the peptides resistant to amino peptidase degradation, suggesting a protective role could be provided by this modification. The prevalence of this modification in the humans lens was then demonstrated using the integral membrane protein Aquaporin 0 (AQP0). By the age of 68, 13% of the N-terminal Met residue of AQP0 had racemised in the cortex, increasing to 28% in the nucleus which is the oldest part of the lens. Other N-terminal modifications studied included the degradation of model peptides via sequential loss of their N-terminal residues. Again it was shown to occur at physiological conditions using model peptides based on crystallin sequences, however further investigation revealed that it was more prominent in phosphate buffer. One potential mechanism involves phosphate buffer acting as a nucleophile. It is worth noting that phosphate buffer is present in the human lens and that this may still be a biologically relevant degradation process. Aged proteins demonstrating sequential loss of amino acid residues or “laddering” have been described in the literature [2]. The potential for proteins to degrade via loss of two amino acids at a time through a cyclic diketopiperazine (dkp) from the N-terminus was also investigated. A range of factors were considered and it was shown to be another potential degradation pathway for long-lived proteins which have a free amino termini. Peptides that have a penultimate Pro residue were particularly prone, with significant dkp formation occurring even at physiological temperatures. For peptides without a penultimate Pro, dkp formation was still observed for a range of peptides, but elevated temperatures were required. The final part of this thesis detailed the isolation and characterisation of a novel UV filter found in the lens of the thirteen-lined ground squirrel. The structure of this UV filter is of interest due to the lens of the thirteen-ground squirrel having a similar UV filter profile to that of the human lens. Characterisation by mass spectrometry and NMR spectroscopy revealed the likely structure to be an N-acetylated 3OH Kynurenine adduct with the incorporation of a proline. A potential structure has been proposed involving the formation of an imine bond between the proline and the 3OH Kynurenine.

One hundred and eight leaders participated in collaborative qualitative research aiming to help the organisation improve professional practice in the development of healthy and effective leaders. Structured conversations, storytelling and other participatory techniques were used to elicit the leaders’ own tacit knowledge to better understand the systemic health issues that they face. Viewing the organisation through complex living systems was found to be a useful framework to explore four cycles of action research inquiry. An aspirational state of ‘optimal functioning’ was identified to assist a shift in leadership practice that emphasises the salutogenic (focus on health and wellness) rather than merely responding to the pathogenic (focus on disease and disorder). Participants co-generated their own theories of transformation, making tacit knowledge explicit through the development of six mapping tools that were designed to share newly found knowledge throughout the organisation. PAR effectively influenced both learning and change, contributing to the launch of three system-wide action interventions: (1) The Centre for Wellness, (2) The Leaders Care Network and (3) Mentoring Training. The result is a holistic approach to leadership development designed to improve the health and effectiveness of leaders across the organisation.

Raykar, Duraiswami and Yegnanarayana (2005) raise several prevalent methods of achieving spatialzation for digital audio, inclusive of HRTF measurement, database matching, numerical modelling and frequency scaling to attempt to match non-individualised HRTFs to an individual. Spatialization of audio developed for headphones is applicable to many purposes – the growing penetration of virtual reality technology, video game environments and application to physical artistic installations, as well as teleconferences demonstrate the variety of environments that this technology could benefit. This project aims to simplify the spatial cues driven by the structure of the human pinna for application to teleconferencing.

The distance, velocity of the source movement and speed of sound in medium determines the how the frequency changes.Doppler shift can be reproduced using programming languages like "Matlab". But usually the reproduction quality of the Doppler shift which is produced using the programming language is not anything similar to the Doppler shift experienced in the real life. This is mainly because there are number factors which are ignored while programming the Doppler shift reproduction program. This review focuses on how to reproduce virtual moving source causing Doppler shift more accurately as heard in the natural world.

Informal conversation about teaching within university departmental contexts represents one way academics learn about university teaching. Such conversations also have the potential to more effectively link learning on formal professional development programs with teaching. As professional development of teaching is usually focused on formal courses, workshops and projects, informal conversation has not been investigated as a professional development strategy. The lack of substantial exploration of conversation as a professional development strategy was the impetus for the current study. This study investigated academics’ experience of informal conversation about teaching within their departments. Thirty academic staff working in different departments at an Australian research-intensive university were interviewed and the transcripts were analysed using grounded theory (Glaser & Strauss, 1967). The analysis revealed that academics were learning about many aspects of teaching from informal conversation with their departmental colleagues. Four elements of informal conversation were explored: the content of conversation, the purpose for which academics used conversation, the context which influenced conversation and the relationship between conversation and formal (course-based) professional development. In summary, academics’ conversations were about topics that included students, assessment, curriculum and evaluation, with their purposes ranging from venting their frustrations, and reassuring themselves, to managing, improving and evolving their teaching. The investigation of the role of contextual influences on informal conversation about teaching yielded a theory for the nature of conversation, based on ‘commonality’. In a context which provides variable support for teaching, increases in commonality between academic colleagues are associated with increases in frequency and usefulness of their informal conversation. The theory of commonality and the description of the nature of informal conversation derived from this study are used to show how informal conversation can enhance professional development.

This paper describes the peer observation model used in the tutor development program in the Faculty of Economics and Business at the University of Sydney, and reports on the effectiveness of this exercise using quantitative and qualitative data from five sources. Results from 32 peer observations reveal both the common strengths and the areas in which tutors need to develop their teaching practice. Ninety four percent of participants found the exercise valuable and 88% said that they would change their teaching as a result of the exercise. This model can be applied in academic development programs in any discipline and suggestions for augmentation and improvement are provided.

MHC class I and class II genes encode cell-surface molecules that are involved in antigen presentation to T cells. This thesis describes the characterization of the MHC in the Tasmanian devil (Sarcophilus harrisii), the largest remaining carnivorous marsupial in the world which is currently under threat of extinction due to a contagious cancer – devil facial tumor disease (DFTD). In order to provide a better understanding of the devil immune system, the genomic organization, gene content, and genetic variation within the devil MHC, particularly within the class I and II regions, were investigated in this project. Four genomic regions containing devil MHC class I and II genes were assembled and annotated using bacterial artificial chromosome (BAC) contigs. All these regions were physically mapped to the same area on the long arm of devil chromosome 4, indicating the genomic location of the devil MHC. Thirty-four genes and pseudogenes were identified, including five class I and four class II (one ɑ chain and three β chain) loci. Comparison between two haplotypes from two individuals revealed three genomic copy number variants within the class I gene region, causing differences in the number of functional class I genes among individuals. Eleven microsatellite markers located adjacent to class I or II genes were developed to facilitate MHC typing in devils. The level of genetic variability within the devil MHC is low. In 60 individuals from across Tasmania, only three, six and three alleles were found at the three class II β chain loci Saha-DAB1, 2 and 3, respectively, exhibiting very limited polymorphisms in the peptide-binding regions. The sole class II α chain gene (Saha-DAA) appeared to be monomorphic. In contrast to other examined marsupials, the devil has only one functional class II gene family, which further restricts its class II diversity. The low MHC variability may have led to increased vulnerability of the devil to evolving pathogens, emerging infectious diseases and environmental changes. For the long-term survival of this iconic species, it is crucial to ensure that further losses of MHC allelic diversity do not occur. Skin graft experiments showed that low MHC diversity may have contributed to delayed allorejection in the devil. However, it was also found that all skin allografts were rejected by Day 21 after transplantation even between MHC-identical individuals, suggesting that allorecognition in the devil likely involves not only major but also minor histocompatibility antigens. These results indicate that low MHC diversity alone does not fully explain the transmission of DFTD across the devil population, and that the tumor is likely to be actively evading the host immunosurveillance. The fundamental work on MHC characterization presented in this thesis has improved our knowledge on devil MHC genes at the genetic, genomic and functional levels, and represents an important step in understanding the role that the MHC has played in the spread of DFTD Sun, 01 Jan 2012 00:00:00 GMT http://hdl.handle.net/2123/9162 2012-01-01T00:00:00Z http://hdl.handle.net/2123/9161 Title: Multi-Effects in MATLAB Authors: Manoleskos, Michael Fri, 07 Jun 2013 00:00:00 GMT http://hdl.handle.net/2123/9161 2013-06-07T00:00:00Z http://hdl.handle.net/2123/9160 Title: Stereo Spreader Authors: Fernandez, Arturo Abstract: The spreader_mod function spreads a mono audio signal though the stereo image summing the dry original signal with a combination of delay and pitch shift which are independently applied to the left and right channels.
