description: Issues of spatial distribution, allocation and access to resources prevail when establishing a long-term and viable e-community within the cultural sector. While e-communities have multiplied in commercial environments, cultural institutions are still challenged by appropriate ways to support collaboration, the nature of institutional messages and the technical infrastructure required. As a guide for institutions in the formation and maintenance of cultural e-communities, this paper introduces the field of Digital Cultural Communication, a new field which examines co-creative relationships between cultural institutions, communities and audiences. By focusing on institutional strategies, community programs and distribution strategies, Digital Cultural Communication can be used by institutions to structure the development of cultural e-communities by providing methods and tools for curators and designers to structure communication and build creative interactive artifacts. This research draws on two existing successful e-communities to illustrate the potential for cultural institutions to develop e-communities where co-created community content can be published in order to extend audience access and interaction.
Who is the corporate entrepreneur? Insights from opportunity discovery and creation theory

description: Recent research has begun to address and even compare nascent entrepreneurship and nascent corporate entrepreneurship. An opportunity based view holds great potential to integrate both streams of research, but also presents challenges in how we define corporate entrepreneurship. We extend (corporate) entrepreneurship literature to the opportunity identification phase by providing a framework to classify different types of corporate entrepreneurship. Through analysis of a large dataset on nascent (corporate) entrepreneurship (PSEDII) we show that these corporate entrepreneurs differ largely from each other in terms of human capital. Prior studies have indicated that independent and corporate entrepreneurs pursue different types of opportunities and utilize different strategies. Our findings from the opportunity identification phase challenge those differences and seem to indicate a difference between the opportunities corporate entrepreneurs identify versus the opportunities they exploit.

description: Many factors affect membrane composition in ectotherms, including allometry, temperature, toxins such as PCB-153, and osmotic stress. This thesis seeks to describe the relationship between membrane composition, size, and phylogeny in twelve species of cypriniform fish; to describe interactions between the homeoviscous responses to temperature and to PCB-153 in goldfish and rainbow trout; and to describe the membrane response to hypoosmotic stress in goldfish. Commonalities in these patterns provide insight into shared mechanisms of phospholipid modulation. In particular, such similarities indicate whether the membrane pacemaker theory of metabolism, which connects allometric relationships between body size, membrane phospholipids, and metabolic rate, can serve as a general framework for understanding membrane composition. Chapter 2 investigates how cypriniform membrane unsaturation decreases with mass through different fatty acid substitutions than in endotherms, but these fatty acids are in turn shown to be due to the species’ relatedness to one another rather than to purely physiological causes. In Chapter 3, PCB-153 is shown to increase cholesterol in liver and brain, while high temperature primarily reduces phospholipid unsaturation. In Chapter 4, these patterns are further explored in trout. As in goldfish, cholesterol modulation is the primary response to PCB-153, whereas temperature primarily reduces phospholipid unsaturation. Trout show more pervasive fatty acid changes than goldfish in all tissues except the liver, which does not respond to PCB exposure, suggesting that PCB-153 pushes trout’s homeoviscous response to a limit that similarly-exposed goldfish do not face. Chapter 5 shows that goldfish intestines decrease membrane saturation; kidneys decrease membrane cholesterol; gills decrease neither; and muscles decrease both in response to long-term exposure to hypoosmotic conditions. The intestine and kidney are both involved in recovering ions from body fluids, but gills suppress ion loss and muscle concentrates ions from the bloodstream. Temperature, osmotic stress, PCB-153, and increasing body size are all addressed via a similar set of membrane responses in fish, which fits with the membrane pacemaker theory’s predictions regarding membrane composition, metabolic rate, and size.
The energy absorption and blast resistance of singly curved sandwich shells
Creators: name: Shen, Jianhu
Publisher: name: Swinburne
Year: 2024

description: Metallic sandwich panels with a cellular core, such as honeycomb or metal foam, can dissipate considerable energy through large plastic deformation under quasi-static or dynamic loading. The curved panels are generally substantially stronger and stiffer than other structural forms and perform better under various loadings. This is due to effectively supporting external loads by virtue of their spatial curvature. A better combination to leverage the advantages of shells and sandwich structures was expected and of great importance for its applications. Furthermore, recent research proved that the flat sandwich panels outperformed monolithic panels of an identical mass per area under blast and impact loadings. It is of great interests with a potential application to study the behaviour of curved sandwich structures under blast and impact loadings. To this end, the blast and impact response and energy absorbing performance of two types of cylindrical shells were investigated experimentally, numerically and analytically. Four different case studies to determine the energy absorption and blast and impact resistance performance of sandwich shells were conducted: (I) the lateral crushing of sandwich tubes compressed by two rigid plates; (II) radial crushing of sandwich tubes under inner blast loading, (III) indentation/penetration resistance of singly curved sandwich panels subjected to foam impact; and finally, (IV) mechanical response of singly curved sandwich panels subjected to blast loads. The deformation and failure patterns of sandwich shells were clarified under various loading conditions as well as the energy absorption mechanisms. Finite element models were developed and validated by these experiments, which provided more detailed deformation and failure information during the loading process. Importantly, these investigations found that: (I) the core crushing is an inherent deformation pattern for sandwich shells under various blast and impact loadings; (II) sandwich shell structures outperform their corresponding monolithic structures only in a certain range, determined by the intensity of blast and impact and the initial geometry features of the sandwich shells; (III) the glue effect between the core and face sheet plays an important role in curved sandwich structures and it is more important for curved sandwich structures with a thin face sheet than that with a thick face sheet; (IV) the strain rate or loading rate effect of the aluminium foam core is relatively small compared with other effects. Besides those findings, two analytical solutions were provided for sandwich tubes under lateral compression and inner blast loadings. Those solutions will enable designer to optimise the sandwich shell structures under blast and impact loadings, which will greatly enhance the blast and impact resistance of curved sandwich structures in various applications.
Unleashing the power of distributed CPU/GPU architectures: massive astronomical data analysis and visualization case study

description: Upcoming and future astronomy research facilities will systematically generate terabyte-sized data sets moving astronomy into the Petascale data era. While such facilities will provide astronomers with unprecedented levels of accuracy and coverage, the increases in dataset size and dimensionality will pose serious computational challenges for many current astronomy data analysis and visualization tools. With such data sizes, even simple data analysis tasks (e.g. calculating a histogram or computing data minimum/maximum) may not be achievable without access to a supercomputing facility. To effectively handle such dataset sizes, which exceed today's single machine memory and processing limits, we present a framework that exploits the distributed power of GPUs and many-core CPUs, with a goal of providing data analysis and visualizing tasks as a service for astronomers. By mixing shared and distributed memory architectures, our framework effectively utilizes the underlying hardware infrastructure handling both batched and real-time data analysis and visualization tasks. Offering such functionality as a service in a 'software as a service' manner will reduce the total cost of ownership, provide an easy to use tool to the wider astronomical community, and enable a more optimized utilization of the underlying hardware infrastructure.

description: Ethical hacking is one important information security risk management strategy business and academic organizations use to protect their information assets from the growing threat of hackers. Most published books on ethical hacking have focused on its technical applications in risk assessment practices. This thesis addressed a gap within the organizational communication literature on ethical hacking. Taking a qualitative exploratory case study approach, the thesis paired technoethical inquiry theory with Karl Weick’s sensemaking model to explore ethical hacking in a Canadian university. In-depth interviews with key stakeholder groups and a document review were conducted. Guided by the Technoethical Inquiry Decision-making Grid (TEI-DMG), a qualitative framework for use in technological assessment, findings pointed to the need to expand the communicative and social considerations involved in decision making about ethical hacking practices. Guided by Weick’s theory, findings pointed to security awareness training for increasing sensemaking opportunities and reducing equivocality in the information environment.

description: Accompanying the increasing interest on Vehicle Ad-hoc Network (VANET), there is a request for high quality and real-time video streaming on VANET, for safety and infotainment applications. Video Streaming on VANET faces extra issues, comparing to the Mobile Ad-hoc Network (MANET), like the high dynamic topology. However, there are also benefits in VANET, like large buffer and battery capacity, predictable motion of vehicles and powerful CPU and GPU. Video streaming on VANET can be highly improved by these features. However the poor performance of wireless networks is an critical issue for video streaming in VANET. The high packet loss probability of wireless networks significantly reduces the quality of the transmitted video. An error recovery process is proposed in our research for high quality and real-time video streaming in VANET, which is call Multi-path Error Recovery Video Streaming (MERVS). The performance improvement of wireless networks is also considered in our research. The cross layer technique is adopted in our research, in order to increase the accuracy on the network condition monitoring and to guarantee the fairness on network resource distribution. Cross layer protocols on both the Media Access Control (MAC) layer and the Network layer are proposed to improve the performance collaboratively. The contribution of my researches are: 1) I proposed a MERVS, which provides high quality and real-time video streaming; 2) several improvement techniques are also designed to improve the performance of MERVS; 3) simulation results verifies that MERVS can have a higher quality on transmitted video comparing to the existing protocols in an acceptable delay.

description: During the last three decades, the significant increase in electricity demand, and its consequences, has appeared as a serious concern for the utility companies, but no major changes have been applied to the conventional power grid infrastructure. Recently, researchers have identified efficient control and power distribution mechanisms as the immediate challenges for conventional power grids. The next step for conventional power grid towards the Smart Grid is to provide energy efficiency management along with higher reliability via smart services, in which the application of Information and Communication Technology (ICT) is inevitable. ICT introduces powerful tools to comply with the smart grid requirements. Among various ICT properties, the telecommunication network plays a key role for providing a secure infrastructure. The two-way digital communication system provides an interaction between energy suppliers and consumers for managing, controlling and optimizing energy distribution. We can also define the smart grid as a two-way flow of energy and control information, where the electricity consumers can generate energy using green energy resources. The main objective of this thesis is to select an effective data communication infrastructure to support the smart grid services by considering a hybrid wireless and optical communication technologies. Radio-over-Fibre (RoF) networks are considered as a potential solution to provide a fast, reliable and efficient network backbone with the optical access network integration and the flexibility and mobility of the wireless network. Therefore, we adopt the integration of RoF to Passive Optical Network (PON) as a broadband access network to transmit smart grid data along with the Fiber to the Home/Building/Curb (FTTx) traffic through the shared fibre, and utilizing Wavelength Division Multiplexing (WDM). Finally, we present and analyze the simulation results for the aforementioned infrastructure based on our enhanced ROF-PON integration model.
How undergraduate students manage their money

description: Jointly funded research between the banking sector and academic institutions in Australian indicates the need for a deeper understanding of how students manage their money as they transition from a state of financial dependence to independence. This transitioning phase has been reported as a time of considerable stress and uncertainty for students with suggestions that coping behaviour adopted in youth may inform behaviour later in life. This research draws from students' personal experience to develop a dynamic systems model that shows the structure of student decision making highlighting a preference for focusing on present situations. This preference defines a student's living space and rationality, illustrating how they construct and reconstruct their perceptions and knowledge in light of dynamic influences to develop individualistic, strategic and opportunistic approaches that reflect their life style choices.
The role of cognitive load in modulating social looking: a mobile eye tracking study

description: The effect of cognitive load on social attention was examined across three experiments in a live pedestrian passing scenario (Experiments 1 and 2) and with the same scenario presented as a video (Experiment 3). In all three experiments, the load was manipulated using an auditory 2-back task. While the participant was wearing a mobile eye-tracker, the participant’s fixation behavior toward a confederate was recorded and analyzed based on temporal proximity from the confederate (near or far) and the specific regions of the confederate being observed (i.e., head or body). In Experiment 1 we demonstrated an effect of cognitive load such that there was a lower proportion of fixations and time spent fixating toward the confederate in the load condition. A similar pattern of results was found in Experiment 2 when a within-subject design was used. In Experiment 3, which employed a less authentic social situation (i.e., video), a similar effect of cognitive load was observed. Collectively, these results suggest attentional resources play a central role in social attentional behaviors in both authentic (real-world) and less authentic (video recorded) situations.

description: The first measurements of the radioactive 135Cs and 134Cs isotopes were made on an accelerator mass spectrometer. The natural Ba interference was suppressed using an isobar separator for anions (ISA) in order to measure the less abundant isobaric 134Cs and 135Cs isotopes. It was found that the Ba interference could be suppressed by a factor of 2 × 10^5 while 25% of Cs was transmitted. Furthermore, through comparing the known natural abundance of Ba isotopes to the measured concentration in a sample it was shown that the ISA does not introduce significant mass dependant fractionation at the level of 0.8%. A slow sequential injection analysis technique was developed to measure 135Cs using 134Cs as a reference isotope. This technique also permitted the monitoring of Ba interference. The ionization efficiency of Cs when analyzed in the molecular anion form, CsF2^- , was on the order of 10^−7 while the total measurement efficiency was 1.7×10^−9. The abundance sensitivity of this system was found to be 135Cs/ 133Cs = (1.3 ± 1.7) × 10^−10 , corresponding to a 3σ detection limit of 132.5 pg of analyte per target. Lastly, using the developed AMS techniques, beta spectroscopy, gamma spectroscopy, and isotope production, a measurement of the half life of 135Cs was made. The two measurements of the half life of 135Cs were 0.72 ± 0.32 Ma and 0.99 ± 0.42 Ma.

description: International and European regulations permit the use of scrubbers to comply with the sulfur limits for marine fuel. Some scrubbers generate wastewater, which is discharged into the marine environment. The current environmental status of German coastal waters is moderate to poor. The contaminated wastewater adds a further stress factor for marine organisms in the North Sea and Baltic Sea as well as the adjacent catchment areas supporting shipping traffic. In principle, the use of clean liquid (diesel) and gas (⁠LNG⁠) fuels is preferable to an exhaust gas aftertreatment for the purpose of sulphur reduction. Based on legal and regulatory policy considerations, current knowledge indicates that imposing limitations of wastewater discharge generated by scrubbers is the best way to prevent the potential damage which results from their use.

description: Twenty-nine hippuricase positive Campylobacter strains were isolated from wild birds and river water. Previous characterization using atpA typing indicated that these strains were related to Campylobacter jejuni and Campylobacter coli but were most similar to three recently described hippuricase-positive Campylobacter species recovered from Zebra finches, i.e., C. aviculae, C. estrildidarum and C. taeniopygiae. Phylogenetic analyses using 330 core genes placed the 29 strains into a clade well separated from the other Campylobacter taxa, indicating that these strains represent a novel Campylobacter species. Pairwise digital DNA-DNA hybridization and average nucleotide identity values were below 70% and 95%, respectively, thus providing further supporting evidence of a novel taxon. Standard phenotypic testing was performed. All strains are microaerobic or anaerobic, motile, Gram-negative, spiral cells that are oxidase, catalase and nitrate reductase positive, but urease negative. Genomic analyses indicate that the 29 strains can potentially synthesize very few amino acids de novo and are auxotrophic for many amino acids and cofactors, similar to the species composing the Campylobacter lari group. In addition, these strains encode complete Entner-Doudoroff and Leloir pathways, suggesting that they may possess the ability to utilize both glucose and galactose; these pathways were also identified in the genomes of the Zebra finch-associated taxa. The data presented here show that these strains represent a novel species within Campylobacter, for which the name Campylobacter molothri sp. nov. (type strain RM10537T=LMG 32306T=CCUG 75331T) is proposed.

description: The discovery of the accelerating expansion of the Universe a decade ago established a new paradigm in Cosmology. The origin of the 'dark energy' which drives this acceleration is not yet understood. In this thesis, we analyzed the statistical distribution of matter mapped by a new, deep galaxy survey (The WiggleZ Dark Energy Survey) to test dark energy models using the formation and evolution of cosmic structure over the last 7 billion years. We find that the properties of dark energy are consistent with a uniform 'cosmological constant' matter-energy filling the Universe, rather than demanding a change to standard Gravity.

description: The increasing waiting times to access healthcare services are a major concern for pa-tients in hospitals. Due to the unpredictability of health issues, hospitals and clinical ser-vices are provided to patients even without prescheduled medical appointments. Unex-pected and random patient arrivals can result in high waiting times. Waiting occurs most-ly because of insufficient resources available compared to demanding service delivery requirements at a given time. Thus, appropriate management of resource scheduling over time can help reduce patient wait times. So far, simulation has mostly been used as a support for strategic decision making in healthcare environments. We are proposing a complementary approach, namely, real-time simulation, to support operational decision making rather than long-term strategic decision making. Real-time simulation is a technique used to get a timely prediction of the system status in a near future (e.g., a few hours). Hospitals can benefit from the capa-bilities of real-time simulations by predicting upcoming bottleneck occurrences in patient care processes and make effective decisions in the present time to avoid undesirable out-comes in the near future. This research presents real-time simulation capabilities for short-term operational decision making of patient care processes in hospitals and the possible ways to run alter-native scenarios and evaluate their results to come up with the most effective solution considering various factors. This thesis also provides tool support based on a leading simulation environment, namely Arena. The tool-supported methodology is evaluated through a realistic cardiac care process in an Ontario community hospital, with encourag-ing results.
Response of reinforced concrete beams with multiple web openings to static load

description: Web openings in beams occur quite often in practice to provide convenient passage of electrical and mechanical ducts. Shear failure may dominate in cases where web opening created or the flexural strength has been increased. In such cases, increasing the shear capacity can prevent catastrophic shear failure. In this paper, the investigation of the response of simply supported reinforced concrete T-beams with multiple web circular openings is presented. An experimental research program was conducted on the shear behavior of simply supported beams subjected to an incremental concentrated static load at mid span. Seven reinforced concrete T-beams were tested with two design parameters, including number of web circular openings (four or six) and the method which was used to strengthen the member at openings (using internal deformed steel bars as in the case of the openings are planned before casting the beams or using carbon fiber reinforced polymer (CFRP) fabric as in the case of the openings will be created in the existing beams). Test results indicated that the strengthening of beams at openings may compensate the decrease of the beam capacity due to the existence of the openings under static loading. The compensation of the beam capacity depends on the strengthening method which was adopted. The gain in shear capacity of the tested beams ranged between 27% and 92% which also represents about 86% to 114% of the reference solid beam capacity under static loading. A nonlinear finite element program, ANSYS 12.1 release, was used to validate the results of the tested beams. Comparisons between the finite element predictions and experimental results in terms of failure loads and load-deflection relationships are presented and showed good agreement.

description: Young people who are homeless experience adversity, but many are able to overcome the challenges of street life and transition back into housing. This exploratory, qualitative research draws on the narratives from interviews and focus groups with 35 young people who have experienced homelessness, as well as interviews and focus groups with 30 service providers working in youth shelters and a youth drop-in centre. Exploring themes of victimization, criminal offending, police involvement, and interactions with community services, this research highlights the capacities of young people to navigate around obstacles and negotiate to meet their needs. Integrating symbolic interactionism and social constructivist perspectives, this research explores the importance of micro-level interactions and perceptions, as well as the contexts that frame the decision-making processes of young people passing through homelessness. The implications of these perspectives are discussed within the framework of resilience discourse.

description: Background Recovery trajectories support early identification of delayed recovery and can inform personalized management or phenotyping of risk profiles in patients. The objective of this study was to investigate the trajectories in pain severity and functional interference following non-catastrophic musculoskeletal (MSK) trauma in an international, mixed injury sample. Methods A prospective longitudinal cohort (n = 241) was formed from patients identified within four weeks of trauma, from attendance at emergency or urgent care centres located in London, ON, Canada, or Chicago, IL, USA. Pain interference was measured via the Brief Pain Inventory (London cohort) or the Neck Disability Index (Chicago cohort). Pain severity was captured in both cohorts using the numeric pain rating scale. Growth mixture modeling and RM repeated measures ANOVA approaches identified distinct trajectories of recovery within pain interference and pain severity data. Results For pain interference, the three trajectories were labeled accordingly: Class 1 = Rapid recovery (lowest intercept, full or near full recovery by 3 months, 32.0% of the sample); Class 2 = Delayed recovery (higher intercept, recovery by 12 months, 26.7% of the sample); Class 3 = Minimal or no recovery (higher intercept, persistently high interference scores at 12 months, 41.3% of the sample). For pain severity, the two trajectories were labeled: Class 1 = Rapid recovery (lower intercept, recovery by 3 months, 81.3% of the sample); and Class 2 = Minimal or no recovery (higher intercept, flat curve, 18.7% of the sample). The “Minimal or No Recovery” trajectory could be predicted by female sex and axial (vs. peripheral) region of trauma with 74.3% accuracy across the 3 classes for the % Interference outcome. For the Pain Severity outcome, only region (axial trauma, 81.3% accuracy) predicted the “Minimal or No Recovery” trajectory. Conclusions These results suggest that three meaningful recovery trajectories can be identified in an international, mixed-injury sample when pain interference is the outcome, and two recovery trajectories emerge when pain severity is the outcome. Females in the sample or people who suffered axial injuries (head, neck, or low back) were more likely to be classed in poor outcome trajectories.

Three Essays on Unconventional Monetary Policy at the Zero Lower Bound

Subjects: unconventional monetary policy
zero lower bound

description: In the first chapter “Impact of Quantitative Easing at the Zero Lower Bound (with J. Dorich, R. Mendes)”, we introduce imperfect asset substitution and segmented asset markets, along the lines of Andres et al. (2004), in an otherwise standard small open-economy model with nominal rigidities. We estimate the model using Canadian data. We use the model to provide a quantitative assessment of the macroeconomic impact of quantitative easing (QE) when the policy rate is at its effective lower bound. In the second chapter “Impact of Forward Guidance at the Zero Lower Bound”, I consider alternative monetary policy rules under commitment in a calibrated three-equation New Keynesian model and examine the extent to which forward guidance helps to mitigate the negative real impact of the zero lower bound. The simulation results suggest that the conditional statement policy prolongs the zero lower bound duration for an additional 4 quarters and reverses half of the decline in inflation associated with the lower bound. It even generates a period of overshooting in inflation three quarters after the initial negative demand shock. Alternatively, the effect of price-level targeting as a forward guidance policy at the zero lower bound is slightly different. In the third chapter “Impact of Quantitative Easing on Household Deleveraging”, I extend the DSGE model in the first chapter with some financial frictions to explore the effects of QE on asset prices and household balance sheet. There are two effects of QE on aggregate output originated from the model. First, QE leads to a decline in term premium, which increases current consumption relative to future consumption. Second, it leads to a lower loan to collateral value ratio and a decline in external finance premium. Favorable financing condition encourages further accumulation of household debt at cheaper rates, in turn, leads to an immediate higher household debt to income ratio. In the consideration of the future withdrawal of any stimulus provided from QE, this would pose greater challenges as it implies much intensive household deleveraging process. I provide some sensitivity analysis around key parameters of the model.

description: This dissertation investigates discourses of anti-violence strategies in the context of international development. While violence against women is, of course, an urgent problem, this dissertation explores how the urgency to end violence against women is socially, culturally, economically, and politically constructed. I consider the manufacturing of urgency in three case studies of contemporary anti-violence initiatives: i) American foreign policy including what has been branded as “The Hillary Doctrine” and proposed International Violence Against Women Act; ii) the World Bank’s report entitled The Cost of Violence; and iii) the United Nation’s UNiTE To End Violence Against Women and Say NO campaigns. In doing so, I argue that World Bank, the United Nations, and American foreign policies are too often technocratic, narrow, depoliticized, and are executed in an urgent manner in the interest of neoliberal economic growth, security concerns, and “feel good” aid at the expense of more holistic, effective and accountable responses to global violence against women.

description: Recently, young children’s educational behavior has become a popular topic for researchers seeking to help develop their skills and abilities in a pleasurable manner. Lately, we have seen the emergence of several communicational units that include powerful and advanced technologies, such as mobile devices. In fact, according to a CISCO report, ‘in 2012 the numbers of mobile-connected devices in circulation are greater than the number of people on earth. By 2016 there will be 1.4 mobile devices per capita, and there will be over 10 billion mobile-connected devices, including (M2M) modules, exceeding the world's population at that time (7.3 billion)’ [1]. In this thesis, we introduce a mobile-based edutainment system called ‘Tap and Learn’ that targets young children and aim to assist them in developing their learning abilities and social communication skills. The Tap and Learn system allows children to learn about new objects and entities in their environments by simply tapping over them with a RFID-mounted smart phone which responds by producing a set of multimedia feedback that aims to foster their learning skills in an entertaining manner. The M-learning system does not require y special tools or environments to be operated and required minimal literacy levels. In addition,, the system enable the parents to participate in their children's learning by allowing them to personalize the learning material and the media content of the games so they suit their children's cognitive level and their learning wants.
Fairness and equality in electoral redistributions in Australia
Creators: name: Newton-Farrelly, Jenni
Publisher: name: Swinburne
Year: 2024

description: The thesis reviewed the way that election districts are drawn for Australia's federal, state and territory elections. It found that the system falls short of providing the equal districts and fair competition that our parliaments intended. Its second task was to provide the methodology required to draw districts which will respond when voters change their support and will give none of the parties an inbuilt advantage. The thesis is the first thorough analysis of Australia's redistribution process and has already helped South Australia's Electoral Districts Boundaries Commission.

Thinking, perceiving and regulating feeling: an investigation of neurocognition, social cognition andemotion regulation in bipolar disorder
Creators: name: Van Rheenen, Tamsyn
Publisher: name: Swinburne
Year: 2024

description: This research comprehensively explored neurocognitive, social cognitive and emotion regulation features of bipolar disorder. It better characterised the profiles of these domains of function and provided an improved understanding of the intricate processes within them, as well as an understanding of their genetic aetiology, shared relationships, and their psychosocial consequences. The findings of this research support assertions that people with the disorder experience cognitive and emotion regulation deficits that meaningfully contribute to psychosocial dysfunction. They also suggest that there may be inherent overlap in brain processes underlying neurocognition and social cognition. Overall, this research has advanced the understanding of bipolar disorder, and it will ultimately contribute to better outcomes for people who experience it by increasing scientific knowledge in the field.
Plato Exits the Pharmacy: An Answer to the Derridean Critique of the Phaedrus and Timaeus

Subjects: Plato

Platonism

description: By framing his deconstruction of Plato’s Phaedrus and Timaeus as a response to Platonism, Jacques Derrida overlooks the possibility of a Platonic philosophy beyond dogma and doctrine. This thesis argues that Derrida’s deconstructions target a particularly Platonist abstraction of the dialogues, and thus, his critique relies on the underlying assumption that Plato defends the metaphysics of presence. Derrida attempts to show how the thesis that Being is presence undermines itself in both dialogues through hints of différance like pharmakon and khôra. To answer the Derridean critique, I analyze the hermeneutics of Derrida’s deconstruction of Plato and identify what in the dialogues lies beyond the limits Derrida’s reading, for example Derrida’s notable exclusion of ἔρως.
Design thinking: expanding the frame of reference - a study of concepts, ideas and thinking tools developed by Edward de Bono that have potential for application within a design process and design thinking framework
Creators: name: Austin, Craig
Publisher: name: Swinburne
Year: 2024

description: This research project focuses on design's ability to bring imaginable worlds out of non-existence into existence and investigates thinking behaviors referred to as design thinking. Underpinning the research is a biological model for the way the brain functions developed by Edward de Bono and the research question asks: can design thinking be enriched with some of de Bono's ideas in order to make the thinking and the process more effective and can some of these ideas be diagrammatically represented? An outcome of the project is the development of a graphic visualisation of a four-stage design process and design thinking schema.

description: Distributed Denial of Service (DDoS) attacks are malicious attacks that aim to disrupt the normal flow of traffic to the targeted server or network by manipulating the server’s infrastructure with overflowing internet traffic. This study aims to investigate several artificial intelligence (AI) models and utilise them in the DDoS detection system. The paper examines how AI is being used to detect DDoS attacks in real-time to find the most accurate methods to improve network security. The machine learning models identified and discussed in this research include random forest, decision tree (DT), convolutional neural network (CNN), NGBoosT classifier, and stochastic gradient descent (SGD). The research findings demonstrate the effectiveness of these models in detecting DDoS attacks. The study highlights the potential for future enhancement of these technologies to enhance the security and privacy of data servers and networks in real-time. Using the qualitative research method and comparing several AI models, research results reveal that the random forest model offers the best detection accuracy (99.9974%). This finding holds significant implications for the enhancement of future DDoS detection systems.

description: Extracellular vesicles (EVs) play a key role in the communication between cancer cells and stromal components of the tumor microenvironment (TME). In this context, cancer cell-derived EVs can regulate the activation of a CAF phenotype in TME cells, which can be mediated by several EV cargos (e.g., miRNA, proteins, mRNA and lncRNAs). On the other hand, CAF-derived EVs can mediate several processes during tumorigenesis, including tumor growth, invasion, metastasis, and therapy resistance. This review aimed to discuss the molecular aspects of EV-based cross-talk between CAFs and cancer cells during tumorigenesis, in addition to assessing the roles of EV cargo in therapy resistance and pre-metastatic niche formation.
