An exploration of the sources of teaching self-efficacy among a sample of early career teachers
No full textTheoretical thesis.Bibliography: pages 55-61.Chapter 1. Introduction -- Chapter 2. Literature review -- Chapter 3. Methodology -- Chapter 4. Results -- Chapter 5. Discussion -- References -- Appendices.In comparison with more experienced teachers, early career teachers report significantly lower levels of self-efficacy. Although the early years of teaching are a critical time for developing teacher self-efficacy, little is known about the sources of early career teacher self-efficacy judgements. Early career teachers (N=40) completed an online questionnaire assessing their self-efficacy. A smaller group (n=25) completed a reflective item which recorded the sources of their self-efficacy beliefs in the context of specific lessons they planned to deliver. Semi-structured interviews with early career teachers reporting low self-efficacy (n=3) and high self-efficacy, (n=4) probed the sources of self-efficacy in relation to the day to day experiences of early-career teaching. Consistent with the literature, participants reported lower teacher self-efficacy than the mean established by Tschannen-Moran and Woolfolk Hoy (2001). The main sources of their self-efficacy were relationships with students, perceptions of student engagement, and feedback and advice received from colleagues. The role of mastery and social persuasions as sources of early career teacher self-efficacy is discussed. Implications for the positive development of early career teacher self-efficacy are discussed.Mode of access: World wide web1 online resource (67 pages) : table
Examining diverse understandings of social justice in planning for sea level rise: a case study of Lake Macquarie, NSW
No full textTheoretical thesis.Bibliography: pages 67-78.Chapter 1. Introduction: planning for sea level rise in the Australian context -- Chapter 2. Review of literature that explores social justice, planning for sea level rise and resettlement -- Chapter 3. Methodology : a qualitative and explorative case study -- Chapter 4. Governance : uncertainty, shifting responsibilities and mistrust -- Chapter 5. Procedural justice : recognition, participation and power -- Chapter 6. Distributional justice : valued places, moral values and retreat -- Chapter 7. Conclusion : Principles for future planning -- Bibliography -- Appendices.How can planning for sea level rise and the option of planned retreat be undertaken in a socially just way? This research applied a social justice framework to examine planning for sea level rise in the densely populated Lake Macquarie area. The Lake Macquarie area has the highest number of dwellings vulnerable to sea level rise in NSW and local adaptation planning for sea level rise is already being undertaken. An in-depth case study was developed through document and media analysis, observations of a community planning workshop, and interviews with key informants and householders. Interviews included local and state government, community stakeholders, and people living in low-lying coastal areas which are likely to be affected by sea level rise, as well as those living in more elevated areas around Lake Macquarie. This qualitative data was analysed thematically through a social justice lens incorporating procedural and distributive justice concerns to identify: the range of understandings of what is just in planning for sea level rise; and key factors that influence perceptions of justice in planned retreat scenarios. The study concludes that there is a need for guiding principles to explicitly address social justice, these are: responsibility; beneficiary pays; redistribution and intergenerational equity.Mode of access: World wide web1 online resource (xi, 88 pages) colour illustrations, colour map
Metal-silicate-sulphide segregation within the Yaringie Hill meteorite
No full textTheoretical thesis."Macquarie Planetary Centre and Macquarie GeoAnalytical (MQGA)" -- title page.Bibliography: pages 47-50.1. Introduction -- 2. Aims and objectives -- 3. Methodology -- 4. Sample descriptions -- 5. Results -- 6. Discussion -- Conclusion -- References -- Appendix.The study of the Yaringie Hill meteorite offers a unique opportunity to investigate the early stages of the planetary building cycle, in particular, the mechanisms controlling core formation. This H5 ordinary chondrite features a crosscutting metal vein that has allowed investigation of metal-silicate-sulphide segregation mechanisms on the ordinary chondrite parent body. This study focused on trace element analysis of metals and sulphides using LA-ICP-MS and the establishment of textural relationships through optical and SEM analysis. The vein metal is depleted in HSE relative to matrix metal, and appears to be the result of injection rather than local partial melting. Comparative study against terrestrial and meteoric segregation mechanisms concludes the vein neither formed via shock metamorphism as previously interpreted, or a smelting process. The vein instead appears to be derived from vapour deposition resulting from impact vapourisation. HSE patterns and abundances relative to iron meteorites highlight the vein being transitional toward the IIIAB irons and pallasites, indicating processes like vapour deposition may contribute to final core composition. Further research in this area should focus on building a larger body of research around the mechanism of vapour deposition and its impact on planetary core formation.Mode of access: World wide web1 online resource (x, 58 pages) colour illustration
Intimate cinema: the proxemics of viewing space and a case study of contemporary queer screen texts and youth identity development narratives
No full textTheoretical thesis.Bibliography: pages 92-99.Chapter One. An auto-ethnographic perspective on ‘networked’ youth & viewing habits -- Chapter Two. Introduction to proxemics -- Chapter Three. Proxemics across mediums -- Chapter Four. Intimate cinematography in contemporary youth-oriented queer screen texts -- Chapter Five. Conclusions -- References.Cinema has played an integral role in the formation of queer politics, community, and subjects. The spaces in which we engage with narratives on screen constitute our reception and relation to texts. Whilst the public movie theatre and queer film festivals have been of key importance in the past, the emergence of personal digital devices has shifted viewing spaces and complicated our definition of public/private spaces. This thesis utilises embodied approaches, and Edward T Hall’s theory of Proxemics, to examine the importance of spatial context in film cognition.Through a case study of contemporary queer screen texts, I explore the nuances of space in interaction between viewers and the screen text. LGBTQIA+ youth are now engaging with queer screen texts in intimate spaces. Safely cocooned in bed with their screens, these ‘Intimate Cinemas’ can be constructed by the individual user for specific purposes. This thesis attends to some possible consequences of these new spaces on queer youth identity development and wider queer politics. I have found that, as our understanding of public/private space has shifted, so too have the epistemologies of out/in upon which the closet and queer narrative scripts have been based.Mode of access: World wide web1 online resource (103 pages) colour illustration
Exploring information systems success and organisational big data analytics capabilities in International Financial Reporting Standard 9 adoption
No full textEmpirical thesis.Bibliography: pages 127-140.Chapter 1. Introduction --- Chapter 2. Literature review -- Chapter 3. Research methodology -- Chapter 4. Results -- Chapter 5. Discussion -- Chapter 6. Conclusion -- 8. Reference list -- Appendices.International Financial Reporting Standard (IFRS) 9 becomes mandatory in January 2018, replacing International Accounting Standard (IAS) 39. The standard introduces a revolutionary forward-looking credit loss model requiring affected entities to calculate and report expected credit losses associated with financial instruments. The new expected credit loss model necessitates entities to use a range of data assets and big data analytical approaches which have not previously been employed for IFRS reporting. Industry analysis has identified the new standard as a practical challenge which impacts data governance frameworks and information systems infrastructures. Extant IFRS, data governance and big data literature does not address the impact of IFRS standard evolution on the data governance frameworks and big data information system infrastructures of affected entities. Moreover, extant literature does not explore the influence of an entity’s capability to conduct big data analytics on their ability to comply with new standard requirements. To address these literature gaps, this study extended DeLone and McLean’s information systems success model with the concepts of organisational big data analytics capabilities and attitudes towards IFRS 9 compliance. The model was then tested by surveying industry professionals involved with international IFRS 9 implementation projects. To evaluate the research model, the results of the survey were analysed using structural equational modelling partial least squares. The primary finding of this study is that the capability of an entity to conduct big data analytics positively affects their employee’s intentions to use IFRS 9 analytics applications and their attitude towards the ability of their entity to comply with IFRS 9. Another key finding is that the quality of the output of information systems used to support IFRS 9 analytics applications positively impacts the intention of affected entity’s employees to use IFRS 9 analytics applications and their attitude towards the ability of the entity to comply with the standard. This study is the first to test an information systems success model in the context of IFRS 9 and is the first to introduce the concept of organisational big data analytics capabilities as an independent variable in information systems success. The study is also relevant to entities which are required to comply with IFRS as it provides empirical research which may help them to develop readiness and capabilities for future IFRS standards.Mode of access: World wide web1 online resource (xii, 195 pages) colour map
Synthesis of novel fluorescent labels for advanced imaging applications
No full textEmpirical thesis..Includes bibliographical references.Chapter 1. Introduction -- Chapter 2. Synthesis of novel amino-salicylaldehyde based fluorescent probes -- Chapter 3. Synthesis and spectroscopic studies of a dual-emitting GFP-analogue -- Chapter 4. Design and synthesis of novel difluoromethylene based fluorescent probes for specific enzyme studies -- Chapter 5. Appendices.A picture is worth a thousand words – they can make large and complex data sets interpretable. In the last six decades, use of fluorescent labelling techniques has extensively increased. Synthesis of fluorescent probes for real-time imaging has become a powerful tool for cell biology, systems biology, microbiology and chemical biology and has largely taken over from radioactive tracers. The accuracy and sensitivity of a fluorescent probe allows the monitoring of complex cellular processes such as enzyme activation, protein-protein interactions, cellular re-organisation and trafficking.This thesis describes the design and synthesis of novel fluorescent labels, studies of their basic photophysical properties, and proof-of-principle applications. Chapter 1 gives a brief introduction of the fluorescence process and fluorescent probes. Chapter 2 consists of the synthesis of novel amino-salicylaldehyde based fluorescent probes. This chapter isdivided into two parts. Firstly, the synthesis of novel pyrylium derivatives as turn-on irreversible protein stain for gel electrophoresis, protein labelling and imaging is described. The second part of the chapter includes the synthesis of novel boranil derivatives and their photophysical properties. Chapter 3 mainly focuses on the resynthesis of a GFP-chromophore analogue, its dual emission, photophysical properties and applications in bioanalytical chemistry. Chapter 4 illustrates the synthesis of a novel turnon, suicide substrates for selected enzymes based on difluoromethyl analogues of wellknown fluorophores. In this chapter, attempts are described towards the synthesis of new fluorogenic fluorescein and BODIPY based derivatives that could be used for the detection of specific enzymes in live cells. Appendices at the end of the thesis provide MS, NMR, U.V and fluorescence measurements.Mode of access: World wide web1 online resource (xiii, 301 pages) colour illustration
Operads and embeddings
No full textTheoretical thesis.Bibliography: pages 45-46.1. Introduction -- 2. Presentation of the existing results -- 3. Introduction to classifiers -- 4. New proof of delooping theoremsIn this thesis, our objective is to present a strategy of a new proof of the weak equivalence Emb(R1, Rm) ∼ Ω2MapOp(D1,Dm), where Emb(R1, Rm) is the space of tangentially straightened long knots in Rm (see [1]) and MapOp(D1,Dm) is the space of operadic morphisms from the little 1-disk operad to the little m-disk operad. The existing proofs of Turchin [2] and Dwyer-Hess [1] are based on homotomy theory. We develop a more categorical proof which uses the theory of internal algebra classifiers [3] and explains conceptually the 'raison d'etre' of such a delooping. It also allows us to employ powerfu categorical/combinatorial techniques developed in [3] for proving and generalising of this sort of results. Our proof should admit a generalisation to higher dimensions, known as Dwyer-Hess conjecture.1 online resource (x, 46 pages
Binary segmentation methods for identifying boundaries of spatial domains
No full textTheoretical thesis.Bibliography: pages 63-67.1 Introduction --2 Methodology -- 3 Numerical results -- 4 Discussion and future directions.Spatial clustering is an important component of spatial data analysis. The aim is to identify the boundaries of domains and their number. It is commonly used in disease surveillance, spatial epidemiology, population genetics, landscape ecology, crime analysis and many other fields. We focus on identifying homogenous sub-regions in an ecology data set. We use binary data indicating the presence or absence of a certain plant species which are observed over a two-dimensional lattice. The problem of finding regional homogenous domains is known as segmentation, partitioning or clustering. To solve this problem we propose to use change-point methodology. We develop new methods based on a binary segmentation algorithm which is a well-known multiple change-point detection method. The proposed algorithms are applied to artificially generated data to illustrate their usefulness. Our results show that the proposed methodologies are effective in identifying multiple domains and their boundaries in two dimensional spatial data.1 online resource (viii, 67 pages : illustrations
Challenges to Nationhood in Postcolonial States: The Case of Pakistan
No full textTheoretical thesis.Bibliography: pages 62-68Abstract -- Statement of Originality -- Introduction -- Chapter 1: The Significance of Islam and Religious Policy Development in Pakistan -- Chapter 2: The Significance of Urdu and Language Policy Development in Pakistan -- Chapter 3: The Significance of ‘Internal Colonialism’ in Pakistan -- Conclusion -- References.Popularly known as an Islamic state, Pakistan is a post-colonial state composed of diverse nations that have distinct languages and associate with different faiths. In heterogenous states, political institutions play an important part in the forging of ethnic ties, as Weber would argue. Pakistan, however, has inherited a colonial legacy and has, thus, adopted a centralised state structure that exploited religion and language to maintain power over its citizens. While other states such as USA, India and Switzerland have managed diversity to the extent that national identity supersedes any other identity, the policy of internal colonialism in Pakistan encouraged communalism, separatism and secession. Even after having suffered the consequences of state centralisation in the case of Bangladesh, the state did not amend its policies to incorporate diversity. Rather, post-1971 Pakistan aggressively exercised control which has challenged the sense of national identity in Pakistan. The aim of this thesis is to identify and explore the challenges to establishing a sense of unified national identity in Pakistan, which is essential for the state to operate in a coherent fashion. It is important to recognise the challenges that a post-colonial state encounters in creating a sense of nationhood for the security and the prosperity of the state.1 online resource ( 68 pages
Podcasting personas in the creative knowledge industries
No full textTheoretical thesis.Includes bibliographical references.Introduction -- 1. Podcasts, participation and personal branding -- 2. When high hopes become high stakes -- 3. Promises, promises -- 4. Potentials in persona studies -- ConclusionUsing digitally networked media to garner attention and build an online reputation has become a popular practice in the information and technology industries (Marwick, 2013). This phenomenon is often subsumed under the rhetoric of individual empowerment that celebrates ideals such as self-expression and entrepreneurialism (Gandini, 2016), and the promising potentials of participation. This thesis investigates how a selection of Australian creative knowledge workers use podcasting to construct networked identities that serve to increase their professional opportunities and build their reputations, yet may simultaneously contribute to experiences of precariousness through the blurring of public and private lives. To understand this tension, I draw on a range of discourses including participatory media studies, affect theory and Persona Studies. The research places early theories of media participation in dialogue with Persona Studies, and proposes that the study of persona may offer a more nuanced understanding of participatory media use in the contemporary moment.1 online resource (77 pages
