description: The development of multicore architectures supporting parallel data processing has led to a paradigm shift, which affects communication systems significantly. This article provides a scalable parallel approach of an iterative LDPC decoder, presented in a tutorial-based style. It is suitable for decoding any irregular LDPC code without the limitation of the maximum node degree, and it includes a parallel calculation of the syndrome. This is the main difference from algorithms presented so far. The proposed approach can be implemented in applications supporting massive parallel computing, such as GPU or FPGA devices. The implementation of the LDPC decoder with the use the OpenCL and CUDA frameworks is discussed and the performance evaluation is given at the end of this contribution.

Liberal multiculturalism, as a political theory, has been developed to overcome the inadequacies of classical liberalism in doing justice to minority groups and their members in a liberal society. Contrary to more traditional forms of liberalism, the multicultural approach to citizenship recognizes citizens as members of distinct ethnic, religious and cultural communities and allows them to enjoy group-differentiated rights in addition to ordinary citizenship rights. It claims that group rights are consistent with liberal principles of individualism, toleration and equality. Kymlicka emphasizes the contribution that secure membership of a cultural community makes to the autonomy of individuals. Galston in his theory of liberal multiculturalism emphasizes the importance to individuals of having the freedom to express their ideas of the good through group membership and being able to live in a society that tolerates difference. From a political perspective, Lijphart advocates a theory of consociational power-sharing among groups as a means for overcoming conflict and oppression of minorities while ensuring that each community can maintain the traditions that member’s value. Liberal multicultural theories and consociationalism were designed to manage conflict and overcome disadvantages of minorities in the context of Western societies. In this thesis these theories are examined in the context of three non-Western countries: Bangladesh, India and Myanmar, with the purpose of determining whether they can be applied to these societies as a means for managing conflict and overcoming group oppression. I argue that the theories are not adequate to achieve these goals in the countries concerned. Kymlicka’s liberal multiculturalism is not tenable in these countries because the liberal values that he uses to justify multiculturalism are not widely held. Galston’s multiculturalism allows for the existence of non-liberal groups but it does not offer a political means of resolving conflicts. Consociationalism is not likely to provide a solution to conflict in countries where intolerance and sectarian violence is prevalent. I develop a theory of multiculturalism for these countries that does not depend on a commitment by their citizens to liberal values. Using Galston’s ideas about building mutuality and toleration and Lijphart’s consociational approach to conflict management I argue that peaceful and just relations between groups are possible in these countries.

description: The goal of this paper is to assess the utility of Reduced-Order Models (ROMs) developed from 3D physics-based models for predicting transient thermal power output for an enhanced geothermal reservoir while explicitly accounting for uncertainties in the subsurface system and site-specific details. Numerical simulations are performed based on Latin Hypercube Sampling (LHS) of model inputs drawn from uniform probability distributions. Key sensitive parameters are identified from these simulations, which are fracture zone permeability, well/skin factor, bottom hole pressure, and injection flow rate. The inputs for ROMs are based on these key sensitive parameters. The ROMs are then used to evaluate the influence of subsurface attributes on thermal power production curves. The resulting ROMs are compared with field-data and the detailed physics-based numerical simulations. We propose three different ROMs with different levels of model parsimony, each describing key and essential features of the power production curves. ROM-1 is able to accurately reproduce the power output of numerical simulations for low values of permeabilities and certain features of the field-scale data, and is relatively parsimonious. ROM-2 is a more complex model than ROM-1 but it accurately describes the field-data. At higher permeabilities, ROM-2 reproduces numerical results better than ROM-1, however, there is a considerable deviation at low fracture zone permeabilities. ROM-3 is developed by taking the best aspects of ROM-1 and ROM-2 and provides a middle ground for model parsimony. It is able to describe various features of numerical simulations and field-data. From the proposed workflow, we demonstrate that the proposed simple ROMs are able to capture various complex features of the power production curves of Fenton Hill HDR system. For typical EGS applications, ROM-2 and ROM-3 outperform ROM-1.

description: Meeting confidentiality requirements in software systems is vital for organizations. Considering confidentiality in early development phases such as the architectural design phase is beneficial compared to late phases such as the implementation because fixing design issues is more cost-efficient in early phases. This tutorial introduces an approach for modeling and statically analyzing confidentiality in software architectures within the Palladio tool suite. Besides foundational knowledge, the tutorial provides a practical hands-on session using the tool. The goal is to show that it is already possible to consider confidentiality in the early design process and that this consideration can be integrated into existing architectural design tools.

description: Knowledge-based planning (KBP) is a method for automated radiotherapy treatment planning where appropriate optimization objectives for new patients are predicted based on a library of training plans. KBP can save time and improve organ at-risk sparing and inter-patient consistency compared to manual planning, but its performance depends on the quality of the training plans. We used another system for automated planning, which generates multi-criteria optimized (MCO) plans based on a wish list, to create training plans for the KBP model, to allow seamless integration of knowledge from a new system into clinical routine. Model performance was compared for KBP models trained with manually created and automatic MCO treatment plans. Two RapidPlan models with the same 30 locally advanced non-small cell lung cancer patients included were created, one containing manually created clinical plans (RP_CLIN) and one containing fully automatic multi-criteria optimized plans (RP_MCO). For 15 validation patients, model performance was compared in terms of dose-volume parameters and normal tissue complication probabilities, and an oncologist performed a blind comparison of the clinical (CLIN), RP_CLIN, and RP_MCO plans. The heart and esophagus doses were lower for RP_MCO compared to RP_CLIN, resulting in an average reduction in the risk of 2-year mortality by 0.9 percentage points and the risk of acute esophageal toxicity by 1.6 percentage points with RP_MCO. The oncologist preferred the RP_MCO plan for 8 patients and the CLIN plan for 7 patients, while the RP_CLIN plan was not preferred for any patients. RP_MCO improved OAR sparing compared to RP_CLIN and was selected for implementation in the clinic. Training a KBP model with clinical plans may lead to suboptimal output plans, and making an extra effort to optimize the library plans in the KBP model creation phase can improve the plan quality for many future patients.

description: Water and sanitation are basic human needs and essential for functional societies but are threatened by climate change. The Covid-19 pandemic has highlighted societal risks, uncertainties and inequalities, while also highlighting the critical role of access to safe water and sanitation services to ensure recovery and resilience. However, climate change is a threat to the delivery of sustainable water and sanitation services.
The water cycle is a primary way that climate change impacts society. According to the IPCC AR6 2021 report, “continued global warming is projected to further intensify the global water cycle, including its variability, global monsoon precipitation and the severity of wet and dry events.” These changes are already affecting water and sanitation services, such as disrupted water supply, and sewers and pit latrines overflowing, requiring increased attention to strengthen their climate resilience.
This brief was prepared by the SWA Research and Learning constituency in support of the 2022 Sector Ministers’ Meeting (SMM) ‘Building Forward Better for Recovery and Resilience.’ It seeks to make available the latest research evidence on climate change, resilience and water, sanitation and hygiene for the preparatory processes leading up to the SMM and to support evidence-based follow-up action.

Confidentiality

description: In our connected world, confidentiality is a central quality requirement. A commonly used mechanism to meet confidentiality requirements is access control. However, access control policies are usually not defined on the architectural abstraction level and are imprecise during design time due to the high degree of uncertainty. This impedes early considerations of confidentiality as implied by "Privacy by Design". We propose an approach to refine and verify access control policies while handling uncertainty that fills the gap between high-level confidentiality requirements and low-level access control.

description: The REACH Programme held a workshop entitled “Socio-economic aspects of flash floods, water and climate” on Wednesday 23rd February 2022 at the Cradle Tented Camp Lodwar, Turkana County. The risks around flash floods, water and climate are among the top worries among the poor population of Lodwar. These risks are experienced differently depending on multiple socio-economic factors. Several organisations have been enabling people’s survival while planning strategic and sustainable solutions to improve people’s lives. However, it is a process with many uncertainties, challenges, unexpected trajectories and undesirable consequences. This meeting aimed to discuss how water and flood risks relate to socio-economic inequalities. There were presentations on critical gender and intersectional considerations on what to think about at the time of interventions, socioeconomic aspects of flash flood risk evaluation and flooding and water insecurity in Lodwar.

description: Base4NFDI is a joint initiative within NFDI (National Research Data Infrastructure Germany), a bottom-up and cross-disciplinary effort to improve research data management and building on 26 communities organised in consortia. Base4NFDI creates a framework for a user-driven and quality-assured portfolio of basic services. It builds on existing solutions that are interoperable with the EOSC infrastructure and follow its guidelines.

Once a potential basic service has passed the formal acceptance criteria, it enters the initialisation phase. Several steps need to be taken and documented to complete this phase.

This document provides practical guidlines to complete the required documentation during the initialisation phase and complements the more formal requirements for completion of the initialisation phase.

description: Subsurface applications including geothermal, geological carbon sequestration, oil and gas, etc., typically involve maximizing either the extraction of energy or the storage of fluids. Characterizing the subsurface is extremely complex due to heterogeneity and anisotropy. Due to this complexity, there are uncertainties in the subsurface parameters, which need to be estimated from multiple diverse as well as fragmented data streams. In this paper, we present a non-intrusive sequential inversion framework, for integrating data from geophysical and flow sources to constraint subsurface Discrete Fracture Networks (DFN). In this approach, we first estimate bounds on the statistics for the DFN fracture orientations using microseismic data. These bounds are estimated through a combination of a focal mechanism (physics-based approach) and clustering analysis (statistical approach) of seismic data. Then, the fracture lengths are constrained based on the flow data. The efficacy of this multi-physics based sequential inversion is demonstrated through a representative synthetic example.

description: Onset detection is an important step for music transcription and other tasks frequently encountered in music processing. Although several approaches have been developed for this task, neither of them works well under all circumstances. In Bauer et al. (2012) we investigated the influence of several factors like instrumentation on the accuracy of onset detection. In this work, this investigation is extended by a computational model of the human auditory periphery. Instead of the original signal the output of the simulated auditory nerve fibers is used. The main challenge here is combining the outputs of all auditory nerve fibers to one feature for onset detection. Different approaches are presented and compared. Our investigation shows that using the auditory model output leads to essential improvements of the onset detection rate for some instruments compared to previous results.

description: A supersymmetric extension of the Skyrme model was obtained recently, which consists of only the Skyrme term in the Nambu-Goldstone (pion) sector complemented by the same number of quasi-Nambu-Goldstone bosons. Scherk-Schwarz dimensional reduction yields a kinetic term in three or lower dimensions and a potential term in two dimensions, preserving supersymmetry. Euclidean solitons (instantons) are constructed in the supersymmetric Skyrme model. In four dimensions, the soliton is an instanton first found by Speight. Scherk-Schwarz dimensional reduction is then performed once to get a 3-dimensional theory in which a 3d Skyrmion-instanton is found and then once more to get a 2d theory in which a 2d vortex-instanton is obtained. Although the last one is a global vortex it has finite action in contrast to conventional theory. All of them are non-BPS states breaking all supersymmetries.

The effect of business-like behaviour on values, norms and operations of student unions: rhetorics, actors and accountability

Year: 2023

description: Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy to the Department of Accounting, La Trobe Business School, Faculty of Business, Economics and Law, La Trobe University, Bundoora.

This thesis examines the effects of business-like behaviours on the values, norms and operations of student unions. It seeks to identify how the corporatisation of the higher education sector has changed the values,norms and how these organisations operate. It also examines how powerful actors in this interplay use language to influence these transformations. This study investigates how accountability is socially constructed within student unions and how accounting is used as a technology or language for change. A qualitative case study approach was adopted and 6 organisations (3 student unions and 3 national bodies, i.e. the National Union of Students, the National Tertiary Education Union, and Council of Australian Postgraduate Associations were involved in this research. This garnered a total of 54 participants who were interviewed face-to-face. Interviews ranged from 30-90 minutes in duration. Observations, primary documents together with interviews were then analysed using document and discourse analysis. These findings will be seen through the lens of Rhetorical Theory of Diffusion (Green,2004) and Orders of Worth (Boltanski and Thevnot, 1999). This thesis contributes a theoretical perspective by bringing together Orders of Worth into Rhetorical Theory of Diffusion, the aim being to better explain the research issues presented here. It also contributes an accounting perspective to existing literature on student unions and adds to accounting studies on higher education reforms by providing a micro-view of corporatisation’s impact on organisations within universities.

description: Dicke's original thought experiment with two spins coupled to a photon mode has recently been experimentally realized. We propose extending this experiment to N spins and show that it naturally gives rise to highly entangled states. In particular, it gives rise to dark states which have resonating valence bond (RVB) character. We first consider a system of N two level spins in a cavity with only one spin in the excited state. This initial state is a linear combination of a dark state and a bright state. We point out the dark state is a coherent superposition of singlets with resonating valence bond character. We show that the coupling to the photon mode takes the spin system into a mixed state with an entangled density matrix. We next consider an initial state with half of the spins in the excited state. We show that there is a non-zero probability for this to collapse into a dark state with RVB character. In the lossy cavity limit, if no photon is detected within several decay time periods, we may deduce that the spin system has collapsed onto the dark RVB state. We show that the probability for this scales as 2/N, making it possible to generate RVB states of 20 spins or more.

description: To investigate the subchronic effect of cadmium intoxication on lipid metabolism and the inflammatory responses accompanying it, rats were administered 50 and 100 ppm cadmium through their drinking water for 7 weeks. At both concentrations, cadmium exposure resulted in significant elevation (p < 0.05) of total cholesterol and gave rise to hypertriglyceridemia in the plasma of the animals. The proinflammatory cytokines, IL-2, IL-6 and TNF-α, were highly expressed in the animals. At the 50 ppm dose level, plasma IL-2, IL-6 and TNF-α levels were increased by 20 %, 87 % and 336 % respectively, while the 100 ppm dose yielded 32 %, 57 % and 470 % increases, respectively. A drastic build-up of MDA in the liver elicited by the metal led to an 85 % increase in lipid peroxidation at high dose. A 3-fold increase of lipid hydroperoxidation (LOOH) products was obtained on exposure to cadmium at 100 ppm. Cadmium caused more than a 2-fold increase in oxLDL levels at both doses tested. Paraoxonase activity was also significantly repressed, culminating in a 43 % reduction in activity at 100 ppm dose. Disruption of lipid metabolism, increased lipid peroxidation as well as imbalance in proinflammatory cytokine levels may thus, be means by which cadmium induces its toxicity.

description: The goal of this case study was to evaluate the effectiveness a 275 m regenerative stream restoration design to mitigate stormwater runoff in a highly urbanized watershed. The restoration resulted in a wide, wetland-like floodplain, comprised of a rock base that was overtopped with a filtration media (approximately 30% woodchips and 70% topsoil). The creation of the floodplain-wetland complex in tandem with filtration media lead to increased storage capacity and an increase in hyporheic exchange within the system. Significant reductions were found for the storm hydrograph parameters volume, peak discharge, and time to peak. Reductions in baseflows were also noted for summer and fall months. Riparian (and in-channel) vegetation played a significant role in storm hydrograph and baseflow changes, likely the result of increased evapotranspiration rates and channel roughness. While water quality was assessed in a limited capacity, preliminary results are positive and are suggestive that the design promotes denitrification.

A cross-cultural comparative study of Japanese and Western perceptions on media systems assessing the validity, or otherwise, of Western criticisms against the Japanese press club media system, and the potential repercussions of new media in Japan, using the Fukushima nuclear disaster as a case in point

description: Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Master of Arts to the School of Social Sciences and Communications, Faculty of Humanities and Social Sciences, La Trobe University, Bundoora.

Western academia is often critical of the Japanese media. The criticisms frequently centre on traits such as extreme exclusivity and a culture of relatively less independent investigative journalism, which are argued to dilute Western ideals of a democratic free press. These traits, however, appear to reflect socio-cultural factors such as collectivist notions of conformity, social harmony, and social deference. This pilot study tests the validity of critics through a comparative analysis of Japanese and Western public opinion, focusing on the Japanese and Western press coverage of the Fukushima nuclear power plant disaster in 2011. Perceptions of new media are also examined to investigate how differences in Japanese and Western dispositions are reflected in the development of new media in Japan and any evidence of potential impacts on the Japanese press club system. The study found high levels of Japanese satisfaction and support for their domestic media system. Compared to Western respondents, Japanese respondents expressed greater support for collectivist thought and less skepticism about powerful social institutions, and low levels of support for civil disobedience. The study also found high levels of support for specific media characteristics which reflect collectivist thought. These include a preference on the part of Japanese media consumers for moderate reporting, the regulation and control of information, and relatively less investigative or ‘watchdog’ journalism. These findings complicate Western criticisms of the Japanese press club media system, since they suggest that the media in Japan — much like their Western counterparts — reflect prevailing cultural customs. The study also reveals higher levels of usage, and more favorable opinions of new media among Western respondents compared to Japanese respondents. This suggests that Japanese society is more resistant to new media. This may be because new media is associated with traits of individualism, evidenced through personalized commentary and opinion, and values of nonconformity through anti-establishment critique.

description: We propose a concept for evaluating signal transformations for music signals with respect to an individual hearing deficit by using an auditory model. This deficit is simulated in the model by changing specific model parameters. Our idea is extracting the musical attributes rhythm, pitch, loudness and timbre and comparing the modified model output to the original one. While rhythm, pitch, and loudness estimation are studied in previous works the focus in this paper concentrates on timbre estimation. Results are shown for the original auditory model and three models, each simulating a specific hearing loss.

description: We investigate the power of the CUSUM test and the Wilcoxon change-point tests for a shift in the mean of a process with long-range dependent noise. We derive analytic formulas for the power of these tests under local alternatives. These results enable us to calculate the asymptotic relative efficiency (ARE) of the CUSUM test and the Wilcoxon change point test. We obtain the surprising result that for Gaussian data, the ARE of these two tests equals 1, in contrast to the case of i.i.d. noise when the ARE is known to be 3/Pi.

description: A high-performance chelation ion chromatography (HPCIC) system using chelating dye impregnated resins for the determination of trace metals in various complex matrices is described. The parameters involved in the production of dye impregnated chelating columns have been identified and optimised, A range of chelating dyes have been impregnated successfully into high-performance substrates, producing a number of chelating columns capable of both metal preconcentration and separations. Each of the chelating columns produced exhibited unique chelating properties. These columns have been classified in terms of metal retention characteristics, separation capability and efficiency, dye loading and column capacities. A number of the above dye impregnated chelating columns have been employed successfully for the determination of trace metals in various sample types. This includes the determination of transition and heavy metals in seawater at low ug dm'^ levels, the determination of aluminium in seawater, the determination of alkaline earth metals in oil-well brines and the determination of barium and strontium in calcium containing matrices such as mineral waters and milk powder.

description: We present physical properties [redshifts (z), star-formation rates (SFRs) and stellar masses (Mstar)] of bright (S850>4mJy) submm galaxies in the ~2deg2 COSMOS and UDS fields selected with SCUBA-2/JCMT. We complete the galaxy identification process for all (~2000) S/N>3.5 850-um sources, but focus our scientific analysis on a high-quality sub-sample of 651 S/N>4 sources with complete multi-wavelength coverage including 1.1-mm imaging. We check the reliability of our identifications, and the robustness of the SCUBA-2 fluxes by revisiting the recent ALMA follow-up of 29 sources in our sample. Considering >4mJy ALMA sources, our identification method has a completeness of ~86 per cent with a reliability of ~92 per cent, and only ~15-20 per cent of sources are significantly affected by multiplicity (when a secondary component contributes >1/3 of the primary source flux). The impact of source blending on the 850-um source counts as determined with SCUBA-2 is modest; scaling the single-dish fluxes by ~0.9 reproduces the ALMA source counts. For our final SCUBA-2 sample we find median z=2.40+0.10-0.04, SFR=287+-6Moyr-1, and log(Mstar/Mo)=11.12+-0.02 (the latter for 349/651 sources with optical identifications). These properties clearly locate bright submm galaxies on the high-mass end of the 'main sequence' of star-forming galaxies out to z~6, suggesting that major mergers are not a dominant driver of the high-redshift submm-selected population. Their number densities are also consistent with the evolving galaxy stellar mass function. Hence, the submm galaxy population is as expected, albeit reproducing the evolution of the main sequence of star-forming galaxies remains a challenge for theoretical models/simulations.

Spousal roles, conflict resolution strategies and life-cycle effects in family consumer decision-making: a study of Saudi husbands
Creators: name: Alghamdi, Abdulaziz Youssef
Publisher: name: La Trobe
Year: 2023

description: Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy to the Business School, Faculty of Business, Economics and Law, La Trobe University, Bundoora.

This thesis presents an exploratory study of the family consumer decision-making (FCDM) process in the context of Saudi Arabia based on the perspectives of a sample of Saudi husbands. Existing studies into FCDM emanate predominantly from Western cultural settings, deploy questionnaire survey methods and offer insights into ‘who’ and ‘what’ questions. Less well developed are insights into the ‘how’ and ‘why’ questions pertaining to the process rather than the antecedents and outcomes of FCDM, especially from under-explored non-Western/Islamic contexts. This study thus investigates spousal roles and conflict resolution strategies in FCDM, and seeks to understand whether and how stage in the family life-cycle, generational and intergenerational influence shape that process. The study deploys an exploratory research design and a qualitative methodology. The sample comprises 14 Saudi men from seven nuclear Saudi families (all married, father-son pairs, resident in the city of Jeddah) identified using a purposive sampling strategy. Data were generated from 30 semi-structured interviews, 8 focus groups and 14 consumer diaries, analysed thematically. The study shows that while spouses play different roles in FCDM (with wives most typically reported as decision initiators and husbands decision gatekeepers), these roles vary according to levels of interest, involvement, product category and conflict. While Saudi spouses deploy a range of conflict resolution strategies, husbands will most typically use their control over household budget and delay/postpone decisions to solve conflict, and adopt passive approaches to conflict resolution. Notable changes in spousal roles, power/control and conflict resolution strategies are reported over the family life-cycle, and mutual intergenerational influence and generational differences are also in evidence in the findings. The primary contribution of the study is the advancement of FCDM theory in general and family power theory in particular by developing a multifaceted insight into the process of FCDM based on concepts previously unexamined in relation to one another. Furthermore, in presenting a context-specific form of knowledge from an under-researched setting, the study generates distinctive cultural insights into FCDM which pluralize the theoretical terrain. A notable limitation of the study is the exclusion of women’s voices from the project for cultural and religious reasons.
Addis Ababa’s water crisis: challenges and opportunities

description: Addis Ababa’s water supply is insufficient to meet current needs, leading to intermittent water supplies which are increasing inequalities in water access depending on access to household storage and finances to develop private wells. Proposals to expand surface water storage will not fully meet the growing demand from the population and expanding industries. Groundwater depletion, land for expanding reservoir storage, water quality and unreliable energy supplies limit opportunities for increasing water provision. Action is needed now to better monitor and manage groundwater use, and to improve the conjunctive use of surface and groundwater to support sustainability for Addis Ababa’s water supplies.

description: An increasing number of studies has demonstrated that learning to read and write influences the way spoken language is processed. While previous research on this field of study almost exclusively investigated orthographic effects on L1 spoken word processing, the present thesis is aimed at extending previous findings to L2 spoken word processing. In the first part of the thesis, a working model of bilingual word recognition is developed, which is able to explain orthographic and phonological interactions during L2 word processing. The architecture of the working model is based on previous outcomes of research on auditory and visual word recognition as well as current findings on orthographic influences during spoken auditory word recognition. In the second part of the thesis, the working model is tested in three psycholinguistic experiments on auditory word recognition (rhyme judgement, phoneme deletion and lexical decision). Special emphasis of the investigation lies on a cross-linguistic comparison between native and non-native speakers of English as well as between two groups of non-native speakers of English with different orthographic backgrounds, i.e. a shallow orthography (German) and a deep orthography (Danish). The results of the experiments show that orthographic information is activated during L2 auditory word processing. However, differences exist between L2 participants from a shallow and a deep L1 orthographic system. These results are discussed with reference to the working model of bilingual word recognition.

description: We investigate the Sommerfeld enhancement (SE) in the generalized scotogenic model with large electroweak multiplets. We focus on scalar dark matter (DM) candidate of the model and compare DM annihilation cross sections to $WW$, $ZZ$, $γγ$ and $γZ$ at present day in the galactic halo for scalar doublet and its immediate generalization, the quartet in their respective viable regions of parameter space. We find that larger multiplet has sizable Sommerfeld enhanced annihilation cross section compared to the doublet and because of that it is more likely to be constrained by the current H.E.S.S. results and future CTA sensitivity limits.
