Development of a long-term climatology of tropical 1 cyclones and depressions for the South Pacific 2 Ocean basin

- Description: Tropical cyclones (TCs) are one of the most destructive synoptic systems that can cause enormous loss of life and property damages in the South Pacific Island nations. The impact of tropical depressions (TDs, i.e., weaker systems that do not develop into TCs) can also be staggering in the region in terms of heavy flooding and landslides, but a lack of complete records (reliable data prior to 1950) often hinders research involving TD impacts. A methodology has been developed here to detect TDs in the ERA-5 (the fifth generation European Centre for Medium-Range Weather Forecasts-ECMWF atmospheric reanalysis of the global climate) and 20CR (the Twentieth Century Reanalysis) dataset using the Okubo–Weiss–Zeta parameter (OWZP) detection scheme. The new South Pacific Enhanced Archive for Tropical Cyclones dataset (SPEArTC), the Dvorak analysis of satellite-based cloud patterns over the South Pacific Ocean basin, rainfall dataset for various stations in the South Pacific and historical archives have been utilised to validate ERA5/20CR-derived TCs and TDs. Results indicate that the OWZP method shows substantial skill in capturing the realistic climatological distribution of TCs and TDs for the South Pacific Ocean in both reanalyses dataset. The 20CR-derived TCs and TDs resemble several key characteristics of the observational records, including spatial distribution of genesis locations and track shapes. This gives us confidence that the 20CR-derived long-term records of TCs and TDs can serve as an effective tool for examining historical changes in various characteristics of TCs and TDs, particularly in the context of anthropogenic climate change. Utilizing the reconstructed proxies of TCs and TDs, their climatic connections with the El Niño Southern Oscillation (ENSO), the Interdecadal Pacific Oscillation (IPO), and the combined ENSO-IPO phases have been examined. Results show clear spatial shifts in TC activity between La Niña and El Niño phases with activity in the region 1400-1700E (1700-2200E) occurring during La Niña (El Niño) events. However, when IPO is considered synergistically with ENSO phases, we found that the combination of El Niño and the positive phase of IPO (+IPO) substantially enhances TC numbers (may be artifact influence) in both domains, noting the modulation between the two phases themselves. Similarly, La Niña and the negative phase of the IPO (-IPO) is found to enhance TC numbers in 1400-1700E. It is shown for the first time that the combined phases of El Niño and +IPO account for increased TC activity, as opposed to the combined phase of La Niña and -IPO, in the eastern sub-region. Similarly, the combined phase of La Niña and +IPO, as opposed to the combined phase of El Niño and -IPO, account for increased TC activity in the western sub-region. However, unlike TCs, the patterns of ENSO variability seem to be reversed for TDs. Changes in large-scale environmental conditions, such as environmental vertical wind shear, low-level cyclonic relative vorticity, mid-tropospheric relative humidity and sea surface temperature are linked to the various modes of variability patterns and their synergistic relationships. Results can have substantial implications, particularly on the predictability of TCs and TDs associated with the two important modes of natural variability in the South Pacific.

Large dataset complexity reduction for classification: An optimization perspective
- Authors: Yatsko, Andrew

- Type: Text , Thesis , PhD
- Full Text:
- Description: Doctor of Philosophy
- Description: Computational complexity in data mining is attributed to algorithms but lies hugely with the data. Different algorithms may exist to solve the same problem, but the simplest is not always the best. At the same time, data of astronomical proportions is rather common, boosted by automation, and the fuller the data, the better resolution of the concept it projects. Paradoxically, it is the computing power that is lacking. Perhaps a fast algorithm can be run on the data, but not the optimal. Even then any modeling is much constrained, involving serial application of many algorithms. The only other way to relieve the computational load is via making the data lighter. Any representative subset has to preserve the data essence suiting, ideally, any algorithm. The reduction should minimize the error of approximation, while trading precision for performance. Data mining is a wide field. We concentrate on classification. In the literature review we present a variety of methods, emphasizing the effort of past decade. Two major objects of reduction are instances and attributes. The data can be also recast into a more economical format. We address sampling, noise reduction, class domain binarization, feature ranking, feature subset selection, feature extraction, and also discretization of continuous features. Achievements are tremendous, but so are possibilities. We improve an existing technique of data cleansing and suggest a way of data condensing as the extension. We also touch on noise reduction. Instance similarity, excepting the class mix, prompts a technique of feature selection. Additionally, we consider multivariate discretization, enabling a compact data representation without the size change. We compare proposed methods with alternative techniques which we introduce new, implement or use available.

- Description: The Android platform is the fastest growing smartphone operating system to date. Consequently, malware on Android OS has been increasing at an alarming rate. Similar to Windows-based malware, Android malware also have different families which are responsible for different malicious activities. In this thesis, we focused on one particular group of Android malware which is designed to target banks and financial institutions. These banking malware use different techniques to attack bank clients and banking servers. A coherent framework to analyse the behaviour of these malware needs to be developed, so the impact of theirs attacks could be minimised. This thesis investigates a systematic analysis to understand these malware’s behaviour and distribution method. From public and private sources, 37 samples of banking malware have been collected which represent eight major Android Banking malware families. In addition, we also analysed malware source code by reverse engineering all malware samples. As a result of analysis, a clear overview and better understanding of mobile banking malware on Android OS was established. The results indicated that Android banking malware is evolving in technique and will become more difficult to analyse in the future.

- Type: Text , Thesis , PhD
- Full Text:
- Description: Text Classification is the task of mapping a document into one or more classes based on the presence or absence of words (or features) in the document. It is intensively being studied and different classification techniques and algorithms have been developed. This thesis focuses on classification of online documents that has become more critical with the development of World Wide Web. The WWW vastly increases the availability of on-line documents in digital format and has highlighted the need to classify them. From this background, we have noted the emergence of “automatic Web Classification”. These mainly concentrate on classifying HTML-like documents into classes or categories by not only using the methods that are inherited from the traditional Text Classification process, but also utilizing the extra information provided only by Web pages. Our work is based on the fact that, Web documents, contain not only ordinary features (words) but also extra information, such as meta-data and hyperlinks that can be used to advantage the classification process. The aim of this research is to study various ways of using the extra information, in particularly, hyperlink information provided by HTML-documents (Web pages). The merit of the approach, developed in this thesis, is its simplicity, compared with existing approaches. We present different approaches of using hyperlink information to improve the effectiveness of web classification. Unlike other work in this area, we will only use the mappings between linked documents and their own class or classes. In this case, we only need to add a few features called linked-class features into the datasets, and then apply classifiers on them for classification. In the numerical experiments we adopted two wellknown Text Classification algorithms, Support Vector Machines and BoosTexter. The results obtained show that classification accuracy can be improved by using mixtures of ordinary and linked-class features. Moreover, out-links usually work better than in-links in classification. We also analyse and discuss the reasons behind this improvement.

What is the perceived effectiveness of fully on-the-job training for carpentry apprenticeships?
- Authors: Wright, Barry
- Date: 2018
- Type: Text , Thesis , Masters
- Full Text:
- Description: This study examined the training experiences of apprentices and employers who were involved in fully on-the-job training in the building and construction trades, specifically in carpentry. Fully on-the-job training, in apprenticeship, means that all training is delivered at the workplace rather than in an institution or training centre and must include structured training arrangements. The apprentice acquires competence through the performance of normal work duties, with some self-managed or facilitated training, as well as receiving support from the appointed Registered Training Organisation (RTO) trainer or trainers, which is all undertaken on the worksite. In the building and construction trades, carpentry apprentices in Australia must gain skills and knowledge over an extensive range of competencies to achieve their qualification. Traditional construction trade jobs have become more specialised over the past 20 years, which could limit the learning activities in terms of tasks and knowledge, resulting in a restricted range of skills. The project investigates this issue and other possible challenges of this delivery model. This qualitative research project involved individual apprentice and employer interviews together with key stakeholder focus group sessions. The research question was: What is the perceived effectiveness of fully on-the-job training for carpentry apprenticeships? Findings included people’s views regarding the advantages, disadvantages, the learning impacts and the outcomes of fully on-the-job training and ways of compensating for limited job roles.

The landscape of my life
- Authors: Woodfield, Linda
- Date: 2007
- Type: Text , Thesis , Masters
- Full Text:
- Description: The investigations surrounding the topic ‘The Landscape of My Life’ questions whether it is possible for a landscape to delineate the way in which we live our lives. For a period of thirty-two years my home has been a historic rural property comprising a dwelling and outbuildings on twenty acres of undulating countryside at Carngham. The work conveys the story of my life at this locale and pursues the motives behind the purchase of the country property, the experiences and remembrances that exist from this period of time and reflects upon the implications of a way of life over the last three decades. While considering the impact that a landscape can have on individual lives, it became important to consolidate the insights that surfaced for me with respect to my own life and works and compare it with that of other selected landscape artists. This comparison took into account personal and family backgrounds, artistic techniques, relationships with the land and the motivations that resulted in the depiction of particular landscapes. The result of these observations led to a consideration that not only can a landscape define the way in which we live our lives but, also identifies an affinity between human beings and the environment.

Positive attitude change to school - Narrative inquiry into adolescent students' lived experiences
- Authors: Wojtaszek, Sylwia
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis reports on a qualitative research study that investigated adolescent students‟ experiences of positive attitude change to school. The literature review situates the research of students‟ attitude changes to school within the affective component of the multidimensional construct of student engagement and identifies this field and the phenomenon of positive attitude change to school as underresearched and under-theorised. Narrative inquiry methodology was applied in order to provide a detailed description of students‟ lived experiences and generate knowledge to fill the existing gap of how such an experience manifests itself. Eight students, who self-reported to have experienced positive attitude change to school, shared stories through in-depth semi-structured interviews of how the attitude change came about, who or what influenced it, and what meaning they attached to it in relation to its impact on their engagement and wellbeing. Students‟ attitudes to school are predominantly examined through quantitative research, whereas this study provided a unique and nuanced insight into attitude change based on the qualitative paradigm and a social constructionist view of the experience from the students‟ vantage point. Students‟ narrative accounts are compared and contrasted with each other to identify five resonant threads associated with the experience of positive attitude change to school. Data analysis suggests that positive attitude change to school has a significant impact on student engagement in learning and student wellbeing through its embodiment of perceived positive emotions associated with being at school. It consequently illustrates the relevance of broadening the understanding of such an experience to address the critical issue of disengagement in adolescent students. Key findings indicate that students develop a negative attitude to school when personal problems remain unresolved or have been insufficiently addressed within the school environment; no “helping hand” was there to assist these ambitious students who were struggling to engage in learning due to their experience of negative emotions at school. This research study has revealed that a negative attitude to school does not necessarily equate to a negative attitude to learning. Students‟ perception of the available support, both from the teachers and the services offered at school, is a critical factor in the transformation of their attitudes to school. Further, the students who participated in this study did not themselves feel that they were equipped with the required knowledge and skills to manage their personal problems effectively in order to maintain their engagement in learning. Only after having “hit rock bottom” and having sought help from outside the school environment were the students able to apply a different perspective to their circumstances that was associated with positive attitude change to school. From this research study it can be concluded that a student‟s positive attitude to school is a requirement for successful social and academic outcomes, and it is an educational goal in itself regarding the notion of developing lifelong learners. Personal problems and their impact on student engagement and wellbeing need to be acknowledged and catered for within the school environment. School support services must proactively extend a helping hand to students who have a negative attitude to school. Further, students need to develop selfefficacy regarding their personal wellbeing so that they become confident to act autonomously in solving their situations at school that are characterised by the difficult negative emotions that they are experiencing. Students‟ attitudes to school and the complexity of the multidimensional construct of student engagement need to be considered in the development of initiatives to address adolescent student disengagement and in the development of student wellbeing frameworks.

Epigenetic modifications in essential hypertension
- Authors: Wise, Ingrid
- Date: 2018
- Type: Text , Thesis , PhD
- Full Text:
- Description: Background: Hypertension (HTN) is a complex, multifactorial, quantitative trait under polygenic control that affects more than one billion people globally. Despite advances in our understanding of the pathophysiology of HTN and the implementation of more effective treatment and prevention strategies, HTN remains one of the world’s great public health problems. The accepted inference from genome-wide association studies (GWAS) is that the genetic code lays the foundation for transcriptomic changes and in turn physiological change. On the other side of the coin, environmental factors (smoking, diet, chemical exposure) can in turn affect DNA itself in genes relevant to blood pressure (BP). Variation in epigenetic forms of modification may thus explain additional phenotypic variation in BP and provide new clues to the physiological processes influencing its regulation. DNA methylation is one of these epigenetic mechanisms responsible for changes to gene expression, activated by interaction with environmental triggers. DNA methylation is a reversible epigenetic modifier of specific dinucleotide sites called CpGs, which consists of a transfer of a methyl group derived from S-adenosyl-L-methionine to position five of a cytosine ring, forming 5mC. Pathophysiologically, the kidney is known as the key organ of BP regulation and one of the most important contributors to HTN. According to the hypothesis put forward by Guyton, over 40 years ago, the control of BP in the steady-state and longer-term is critically dependent on renal mechanisms. In fact, almost all monogenic forms of HTN are driven by rare mutations in genes involved in salt handling in the distal nephron. It is therefore crucial to understand kidney DNA methylation changes that may drive gene expression in kidney and lead to HTN. Hypothesis: The central hypothesis underpinning this PhD thesis is that alterations in kidney specific DNA methylation plays a fundamental role in modulating gene expression changes involved in the regulation of BP and pathophysiology of EH. Aims: This PhD thesis focuses on characterising the role of DNA methylation in the hypertensive kidney using array and RNA-sequencing methods. Three major aims are addressed: • Aim 1: To characterise blood and kidney global DNA methylation dynamics and its functional role in the hypertensive population (Chapter 3). • Aim 2: To determine the role of genome-wide, loci specific DNA methylation in the hypertensive human kidney (Chapter 4). • Aim 3: To understand the relationship between DNA methylation and differential expression of genes associated with BP and HTN in the human kidney (Chapter 5). Results: In Aim 1 global DNA methylation changes were characterised in peripheral blood leukocyte and kidney DNA of the hypertensive (HT) population using he ELISA method. We found no association between HTN diagnosis and global methylation percentage in either peripheral blood leukocytes or kidney DNA. However, a negative correlation was found between global methylation and diastolic blood pressure (DBP), yet this relationship was not evident after adjustment for the effect of antihypertensive medication. Furthermore, we investigated the sensitivity of ELISA-based global methylation detection by calculating the percentage of global methylation in kidney using array based methods; the results were similar, demonstrating no association between HTN diagnosis and median kidney methylation

- Description: Background: Hypertension (HTN) is a complex, multifactorial, quantitative trait under polygenic control that affects more than one billion people globally. Despite advances in our understanding of the pathophysiology of HTN and the implementation of more effective treatment and prevention strategies, HTN remains one of the world’s great public health problems. The accepted inference from genome-wide association studies (GWAS) is that the genetic code lays the foundation for transcriptomic changes and in turn physiological change. On the other side of the coin, environmental factors (smoking, diet, chemical exposure) can in turn affect DNA itself in genes relevant to blood pressure (BP). Variation in epigenetic forms of modification may thus explain additional phenotypic variation in BP and provide new clues to the physiological processes influencing its regulation. DNA methylation is one of these epigenetic mechanisms responsible for changes to gene expression, activated by interaction with environmental triggers. DNA methylation is a reversible epigenetic modifier of specific dinucleotide sites called CpGs, which consists of a transfer of a methyl group derived from S-adenosyl-L-methionine to position five of a cytosine ring, forming 5mC. Pathophysiologically, the kidney is known as the key organ of BP regulation and one of the most important contributors to HTN. According to the hypothesis put forward by Guyton, over 40 years ago, the control of BP in the steady-state and longer-term is critically dependent on renal mechanisms. In fact, almost all monogenic forms of HTN are driven by rare mutations in genes involved in salt handling in the distal nephron. It is therefore crucial to understand kidney DNA methylation changes that may drive gene expression in kidney and lead to HTN. Hypothesis: The central hypothesis underpinning this PhD thesis is that alterations in kidney specific DNA methylation plays a fundamental role in modulating gene expression changes involved in the regulation of BP and pathophysiology of EH. Aims: This PhD thesis focuses on characterising the role of DNA methylation in the hypertensive kidney using array and RNA-sequencing methods. Three major aims are addressed: • Aim 1: To characterise blood and kidney global DNA methylation dynamics and its functional role in the hypertensive population (Chapter 3). • Aim 2: To determine the role of genome-wide, loci specific DNA methylation in the hypertensive human kidney (Chapter 4). • Aim 3: To understand the relationship between DNA methylation and differential expression of genes associated with BP and HTN in the human kidney (Chapter 5).

Organic matter dynamics in willow and eucalypt lined central Victorian streams

- Description: The spread of exotic willows (Salix spp.) in SE Australia, New Zealand and South Africa has provoked widespread debate in scientific, management and broader communities. In Australia, the extent of spread is unknown, but at least 30000 km of river frontage in Victoria are lined by willows. Management and research literature has identified the poor knowledge of willow impacts on Southern Hemisphere aquatic ecosystems. It has been speculated that the major distinction between deciduous willows and evergreen native vegetation will be the timing and quality of litterfall. This would have flow-on consequences for metabolic processes, stream biota and water quality at reach, stream and catchment scales. These two vegetation types were studied through the preparation of partial organic matter budgets for native and willow lined reaches in a central Victorian catchment. Organic matter inputs from litter, groundwater and gross primary production (GPP), organic matter standing crop . and respiratory output were quantified. Total inputs to willow and native reaches were similar (735 and 764 g ash free dry weight m•' yl, respectively). Inputs were dominated by litterfall (-60%) and there were no significant differences in annual litterfall between sites. GPP contributed -20% of total inputs and estimates suggested there were few significant differences in annual GPP, 24 h community respiration, ratio of GPP to community respiration (PIR) or net daily metabolism (NDM) between sites. Groundwater contributed -20% of total inputs with one third of the dissolved organic matter sourced during short flow paths through riparian sediments. Aggradation at willow sites appeared to increase the riparian flow path. Willow and native sites were heterotrophic and similarly dependent on allochthonous organic matter (P/R=O.2, NDM= -.6, and ratio of net primary production to total inputs -0.1). Willow research and management should also focus on retention capacity, including the recruitment and role of LWD and the structure and function of root systems. Removal of willows potentially facilitates native vegetation establishment but simultaneously decreases retention capacity and metabolic control by the canopy. Establishing native vegetation to fulfil broader biodiversity objectives whilst retaining willows for their potentially positive roles is a management challenge. In principle, establishing native species on the upland-sides of fringing willows and under willow canopies will direct succession toward a preferred outcome without destructive disturbance. Understanding of when benefits of willows outweigh their costs is a notable gap.

What is the value of meaning created through social learning in informal virtual communities?
- Authors: Wilmott, Deirdre

- Type: Text , Thesis , PhD
- Full Text:
- Description: This study asks the question ‘What is the value of meaning created through social learning in informal virtual communities?’. By researching how people learn in two virtual communities of practice, based around forums, it endeavours to explore learning in online environments that are unconnected to workplace or educational institutions. Both communities studied in this project are meeting places for peers who pursue a domain of personal interest, hence neither community defines itself as a learning environment but as a social meeting place for people to share similar pursuits. The rationale of this study was to explore in-depth the plethora of resources that forum-based communities offer researchers of learning outside the academy, in order to understand the intricacies of un-facilitated social learning. A research strategy for this study was developed from Crotty's (1998) platform which defines: research methods; a methodology; a theoretical perspective; and an epistemology. Triangulated research methods of interview, observation, and personal participation form the basis of data collection. Ethnography, which incorporates auto-ethnography, was the chosen methodology, and the study is centred on a constructivist epistemology. This study employs an interpretivist theoretical perspective, relying on the approaches of two theorists to analyse the data. Both communities were explored by developing four specific propositions from an in-depth analysis of the available literature on informal learning, virtual environments and communities, together with the theoretical understandings of Wenger (1998) regarding Communities of Practice, and Candy (1991) relating to autodidactic and constructed learning. Two viewpoints were chosen because whilst there are a number of theoretical perspectives that can be applied to informal learning in a virtual environment, there is no one agreed theory which comprehensively explains the complexities of individual and social learning in virtual communities. Despite recognition of the Internet as a major source of many people’s informal learning, there is still comparatively limited research undertaken on how this happens. This study is intended to assist in the reduction of this gap by examining aspects of learning including: the connection between autonomous learners and virtual communities; the effect of the written format of the communities observed on dispersing meaning; and the impact of the virtuality of the community on the process of learning and creation of meaning. By undertaking an ethnographical examination of the nature of learning in two informal virtual communities based around written asynchronous forums, this study is intended to contribute to understanding the worth of informal learning in virtual communities where learning occurs between peers. This study contributes to knowledge through its exploration of the way learning occurs in un-facilitated environments and the legitimacy of the outcomes of that learning. Through this exploration, it fosters an appreciation of the value of meaning created in these social environments, as well as their role in validation of communal and individual meaning. It is able to do this by circumnavigating the difficulties earlier researchers have had in developing in-depth studies of the topic because it does not rely implicitly on the perspectives of those participating, or limited-time observations. The study concludes that for both communities their virtuality greatly influences the way their practice develops, as well as how this practice shapes the way in which their members learn in informal environments. It also concludes that learning in these environments is a very complex, often sophisticated, and sometimes contradictory process that is governed by many different, and occasionally competing, aims of individuals and communities. This study also resolved that because of the very complexity of this learning, these two communities produce some very deep and meaningful contributions to their respective domains. As individuals connected within these communities in order to explore their interest in their respective domains, the communities became: repositories of ideas and resources; places to engage in negotiating and renegotiating meaning; and places to validate personal meaning through testing against established community understandings and peer views. Thus after extensive ethnographical research on both communities of this study, it is considered that this work advances the knowledge of learning outside the academy by providing evidence that people do learn effectively in informal virtual communities

The Melbourne art scene and the Victorian artists’ society 1870-2020
- Authors: Williams, Graeme
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis is a socio-cultural history, utilising the Victorian Artists’ Society as a longitudinal case study to look at the extent to which it has serviced the professional needs of artists. The Victorian Artists’ Society, formed in 1870, is the oldest organisation representing the visual arts in Victoria and, as such, is an appropriate vehicle to examine the discourse between history and the construction of cultural values in the visual arts in Melbourne. The Melbourne ‘art scene’ has existed since Victoria’s proclamation as a separate colony in 1851. During the greater part of this time, the Victorian Artists’ Society functioned as a meeting and an exhibition space for visual artists. Although it is Australia’s second oldest continuous organisation representing visual artists, the Society has been uncontroversial and largely ignored by academics as a focus of research in its own right. Notwithstanding, the two groups subject of the most academic attention and research, namely the Australian Academy of Art and the Contemporary Art Society, were announced and formed within its walls, with many of their key proponents members of the Society. Researching extensive archival records, this thesis explores the relationship that existed between the Society and Melbourne’s art community throughout its 150-year history. It historically interrogates to what extent the Society has been a harbinger for change. Through a study of organisations and events impacting the Melbourne art scene, the thesis argues the relevance of the Society to professional and amateur artists today. It reviews how societies, and clubs in general, once servicing the needs of all artists, have evolved into a more general function, and what role the emergence of the commercial gallery system played as the main platform for the success of the artist. Finally, it examines what sustains, inspires, and informs contemporary professional artists working in Melbourne today.

Unnatural alliances : Immanent reading and the speculative sensations of life
- Authors: Williams, Dominic
- Date: 2018
- Type: Text , Thesis , Doctor of Philosophy
- Full Text:
- Description: It is my claim that Gilles Deleuze’s expressionism allows for a new theory and praxis of reading called Immanent Reading, different from both his own Schizoanalytic praxis and the referential and ontological theories informing Literary Theory. Immanent reading, I propose, following Colebrook’s readings of Deleuze, offers an ethics of reading emphasising the pure immediacy of relations, including those expressed by life. It is upon this primary vector that this thesis progresses: the broad articulation and creation of a theory of Immanent Reading. To achieve this, I claim that the expressionist metaphysics exposed by Deleuze in Spinoza and Leibniz is altered by Deleuze in his own conceptual creations (as with becoming and immanence) and persists as a properly Deleuzian expressionism. The degrees of expression I propose belong to immanent reading are, without necessary order, the written-body, the reader-body, and a milieu of becoming that composes them together and transforms their affective and perceptive compositions. The written-body distinguishes itself as a creation of percepts and affects in writing, the reader-body through its involvement of pliable perceptions and affections, and becoming through its transformative capacity on these affective and perceptive complexes. The concept of immanence subtends this expressive composition, drawing reading into pure immediacy while articulating it as a process of unnatural encounters for “a Life”. To avoid representations of life in demonstrating the praxis, this thesis engages with speculative literature. Deleuze has made use of speculative writers, such as Lovecraft and Asimov, to create his (with and without Guattari and Parnet) concept of becoming. Here I engage with Le Guin, McCarthy, and Stanley Robinson amongst others. The consequence of composing an encounter with speculative literature for immanent reading is multi-fold, with this thesis theorising an expressionist logic in the creation of speculative sensations and the becomings they herald.
