description: The thesis aimed to examine the significance of psychosocial factors (culture, self-construal, psychological well-being, and personality) in predicting SNS usages. Three quantitative studies were conducted. The first study identified cross-cultural differences in SNS usages between Malaysia, South Korea and China, and found the significance of the self-construal in predicting SNS usages. The second study revealed the significance of the severity of depression and OCD symptoms in predicting pathological use of SNS. The final study revealed that different personality traits (Openness to Experience; Dark Triad) predicted SNS usages differently. These results supported the significance of psychosocial factors in predicting SNS usages.

subject: Employment equity and diversity

description: The purpose of this chapter is to explore the diversity, equity and inclusion issues experienced by skilled migrants. Many issues relate to obtaining employment in jobs aligned with their overseas acquired experience and qualifications and the challenges they face in establishing a career in the new host country. Experiences of subtle and direct racism, gender diversity within skilled migrant groups and feelings of marginalisation are explored. Conversely, shining a light on the positive contributions skilled migrants make in regional communities and DEI awareness initiatives allows regions and regional employers to better understand the challenges skilled migrants face. This enables these communities and employers to be better informed when building strategies to attract and retain skilled migrants and their families to regional communities. The chapter presents two case studies of research conducted with skilled migrants in Australia. Both cases provide theoretical perspectives, research designs and data collection methods applied in the field to explore the research questions posited.

description: The main objective of this study is to identify the Challenges and Opportunities of Implementing various Electronic-Payment Projects: taking CBE birr mobile payment system as a case study. To this end, the study employed quantitative and qualitative research approach; descriptive design to construct meaning from extracted data collected from primary and second sources through survey and document review. The primary data collected by using judgmental sampling method 20 respondents selected out of 55 targeted CBE Birr officers, 20 respondents selected from 68 CBE Birr agents and merchants, and 20 CBE Birr customers selected judgmentally. The generated data was analyzed using tables, frequency and percentage approaches. Accordingly, the study came up with the findings that the most challenging factor to the implementation of CBE Birr service is ambiguity on duty and responsibility, mal operation practice by agents, lack of employees' technical knowledge on CBE Birr & police clearance for agent recruit. Despite the above-mentioned and other challenges, the study showed that Growing acceptance of CBE Birr, ICT Infrastructure and NBE's policy direction that enforce banks to adopt technological innovation are some of the major opportunities identified by the study. Moreover, the study recommended that CBE should develop procedure and a guideline to eliminate ambiguity on duty and responsibility, to eliminate mal operation practice by agents the bank should improve the system to control the mal operation practice through calculating the commission of agents by percentage of the money transfer, the bank should be organized and established with skilled manpower to give support 24hrs a day and 7 days a week for CBE Birr services, the bank should decentralize creation of electronic money at least at district office, and finally for police clearance requirement of agent creation the bank should facilitate the process for e.g. by taking the Prospect agent thumb print for police clearance.

description: In this paper, we present a new approach to learning cascaded classifiers for use in computing environments that involve networks of heterogeneous and resource-constrained, low-power embedded compute and sensing nodes. We present a generalization of the classical linear detection cascade to the case of tree-structured cascades where different branches of the tree execute on different physical compute nodes in the network. Different nodes have access to different features, as well as access to potentially different computation and energy resources. We concentrate on the problem of jointly learning the parameters for all of the classifiers in the cascade given a fixed cascade architecture and a known set of costs required to carry out the computation at each node.To accomplish the objective of joint learning of all detectors, we propose a novel approach to combining classifier outputs during training that better matches the hard cascade setting in which the learned system will be deployed. This work is motivated by research in the area of mobile health where energy efficient real time detectors integrating information from multiple wireless on-body sensors and a smart phone are needed for real-time monitoring and delivering just- in-time adaptive interventions. We apply our framework to two activity recognition datasets as well as the problem of cigarette smoking detection from a combination of wrist-worn actigraphy data and respiration chest band data.

description: Swarms of robots will revolutionize many industrial applications, from targeted material delivery to precision farming. However, several of the heterogeneous characteristics that make them ideal for certain future applications --- robot autonomy, decentralized control, collective emergent behavior, etc. --- hinder the evolution of the technology from academic institutions to real-world problems. Blockchain, an emerging technology originated in the Bitcoin field, demonstrates that by combining peer-to-peer networks with cryptographic algorithms a group of agents can reach an agreement on a particular state of affairs and record that agreement without the need for a controlling authority. The combination of blockchain with other distributed systems, such as robotic swarm systems, can provide the necessary capabilities to make robotic swarm operations more secure, autonomous, flexible and even profitable. This work explains how blockchain technology can provide innovative solutions to four emergent issues in the swarm robotics research field. New security, decision making, behavior differentiation and business models for swarm robotic systems are described by providing case scenarios and examples. Finally, limitations and possible future problems that arise from the combination of these two technologies are described.

description: We use the quantum unimodular theory of gravity to relate the value of the cosmological constant, $Λ$, and the energy scale for the emergence of cosmological classicality. The fact that $Λ$ and unimodular time are complementary quantum variables implies a perennially quantum Universe should $Λ$ be zero (or, indeed, fixed at any value). Likewise, the smallness of $Λ$ puts an upper bound on its uncertainty, and so a lower bound on the unimodular clock's uncertainty or the cosmic time for the emergence of classicality. Far from being the Planck scale, classicality arises at around $7 \times 10^{11}$ GeV for the observed $Λ$, and taking the region of classicality to be our Hubble volume. We confirm this argument with a direct evaluation of the wavefunction of the Universe in the connection representation for unimodular theory. Our argument is robust, with the only leeway being in the comoving volume of our cosmological classical patch, which should be bigger than that of the observed last scattering surface. Should it be taken to be the whole of a closed Universe, then the constraint depends weakly on $Ω_k$: for $-Ω_k < 10^{-3}$ classicality is reached at $ > 4 \times 10^{12}$ GeV. If it is infinite, then this energy scale is infinite, and the Universe is always classical within the minisuperspace approximation. It is a remarkable coincidence that the only way to render the Universe classical just below the Planck scale is to define the size of the classical patch as the scale of non-linearity for a red spectrum with the observed spectral index $n_s = 0.967(4)$ (about $10^{11}$ times the size of the current Hubble volume). In the context of holographic cosmology, we may interpret this size as the scale of confinement in the dual 3D quantum field theory, which may be probed (directly or indirectly) with future cosmological surveys.

description: The maximum mass of a nonrotating neutron star, $M_{\rm TOV}$, plays a very important role in deciphering the structure and composition of neutron stars and in revealing the equation of state (EOS) of nuclear matter. Although with a large-error bar, the recent mass estimate for the black-widow binary pulsar PSR J0952-0607, i.e. $M=2.35\pm0.17~M_\odot$, provides the strongest lower bound on $M_{\rm TOV}$ and suggests that neutron stars with very large masses can in principle be observed. Adopting an agnostic modelling of the EOS, we study the impact that large masses have on the neutron-star properties. In particular, we show that assuming $M_{\rm TOV}\gtrsim 2.35\,M_\odot$ constrains tightly the behaviour of the pressure as a function of the energy density and moves the lower bounds for the stellar radii to values that are significantly larger than those constrained by the NICER measurements, rendering the latter ineffective in constraining the EOS. We also provide updated analytic expressions for the lower bound on the binary tidal deformability in terms of the chirp mass and show how larger bounds on $M_{\rm TOV}$ lead to tighter constraints for this quantity. In addition, we point out a novel quasi-universal relation for the pressure profile inside neutron stars that is only weakly dependent from the EOS and the maximum-mass constraint. Finally, we study how the sound speed and the conformal anomaly are distributed inside neutron stars and show how these quantities depend on the imposed maximum-mass constraints.

Radiation therapy for non-small cell lung cancer : the role of combined molecular and anatomical imaging
Creators: name: Everitt, Sarah Jane
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: This thesis comprises a series of studies that focus on approaches for improving potentially curative radiation therapy (RT) administered to patients with lung cancer and the significant role of combined molecular and anatomical imaging technologies in this field. Radiation therapy is the primary modality utilised for treating locally advanced non-small cell lung cancer (NSCLC) and early stage disease in patients unsuitable for surgical intervention. Despite continual attempts to improve the administration of RT for lung tumours, our ability to enhance local tumour control and patient survival have barely improved in the last four decades. Tremendous scope therefore remains to enhance the effectiveness of treatment delivered to patients who are diagnosed with this sinister disease. […] The work described in this thesis indicates that timely treatment after diagnosis is essential for NSCLC as is customisation of radiation therapy treatment plans for individual patients. The concept of geographic miss introduced here was found to be useful to describe both the differences between treatment techniques and the variations in target coverage due to updated and improved imaging information. Together, the initiatives described in this thesis utilise anatomical and molecular imaging to characterise NSCLC in the pre and on-treatment phases of RT. Compared to the current standardised approach to RT delivery, these studies are aimed at delivering personalised regimes guided by the individual anatomical and functional characteristics of these tumours. It is hoped that the future application of these findings will achieve greater success, both in terms of tumour control and long term survival, for patients undergoing RT for the treatment of NSCLC.

description: This work provides formal safety guarantees for control systems with disturbance. A disturbance observer-based robust safety-critical controller is proposed, that estimates the effect of the disturbance on safety and utilizes this estimate with control barrier functions to attain provably safe dynamic behavior. The observer error bound - which consists of transient and steady-state parts - is quantified, and the system is endowed with robustness against this error via the proposed controller. An adaptive cruise control problem is used as illustrative example through simulations including real disturbance data.

description: The successful observation of M87 supermassive black hole by the Black Hole Event Horizon Telescope(EHT) provides a very good opportunity to study the theory of gravity. In this work, we obtain the exact solution for the short hair black hole (BH) in the rotation situation, and calculate in detail how hairs affect the BH shadow. For the exact solution part, using the Newman-Janis algorithm, we generalize the spherically symmetric short-hair black hole metric to the rotation case (space-time lie element (2.25)). For the BH shadow part, we study two hairy BH models. In model 1, the properties of scalar hair are determined by the parameters $α_{0}$ and $L$. In model 2, the scalar hair of the BH is short hair. In this model, the shape of the BH shadow is determined by scalar charge $Q_{m}$ and $k$. In general, various BH hairs have different effects on the shadows, such as non-monotonic properties and intersection phenomena mentioned in this work. Using these characteristics, it is possible to test the no-hair theorem in future EHT observations, so as to have a deeper understanding of the quantum effect of BHs. In future work, we will use numerical simulations to study the effects of various hairs on BHs and their observed properties.

Unavoidable Higgs coupling deviations in the $Z_2$-symmetric Georgi-Machacek model

description: The $Z_{2}$-symmetric version of the Georgi-Machacek model does not possess a decoupling limit in which all the new particles can be made arbitrarily heavy, opening the possibility that the model can be entirely excluded if experiments reveal no deviations from the Standard Model. We explore this model, focusing on the part of parameter space in which the vacuum expectation value of the triplets, $ν_χ$, is small. In the small-$ν_χ$ limit, the second custodial-singlet scalar field $S$ necessarily becomes very light and can contribute to the total width of the 125 GeV Higgs boson $h$ via $h \to SS$. We show that this process, together with LHC measurements of the $h \to γγ$ rate, entirely excludes masses $m_S < m_h/2$ and thereby severely constrains the parameter space, setting an experimental lower bound $ν_χ\gtrsim 12.5$ GeV on the vacuum expectation value of the triplets. This lower bound makes it impossible to avoid deviations from the Standard Model in the couplings of $h$ to fermion and vector boson pairs. We study the remaining parameter space after imposing constraints from direct searches for the additional Higgs bosons, and show that it is on the edge of being fully excluded at $95\%$ confidence level by LHC measurements of the 125 GeV Higgs boson's couplings. Measurements of these couplings at the future high-luminosity run of the LHC will have sufficient precision to entirely exclude the model at $5σ$ if no deviations from the Standard Model are observed.

description: In this work, we discuss how the use of the symmetries well motivated in physics beyond the Standard model (BSM) can guarantee the high quality axions. We avoid to introduce symmetries only useful for addressing the axion quality problem. Rather, we rely on symmetries well motivated by other issues in BSM: supersymmetry, $U(1)_{\rm B-L}$ and the discrete R-symmetry $Z_{NR}$. We show that the interplay among these guarantees the high quality of the axion even for the gravitino mass and axion decay constant as large as $m_{3/2}=\mathcal{O}(10){\rm TeV}$ and $F_{a}=\mathcal{O}(10^{15}){\rm GeV}$ respectively. The key point of this work relies on the observation that the MSSM contribution to the mixed anomalies $Z_{NR}-[SU(2)_{L}]^{2}$ and $Z_{NR}-[SU(3)_{c}]^{2}$ is not enough for gauging $Z_{NR}$ for $N\neq6$, which necessitates the introduction of new matter fields. We make the introduction to achieve zero mixed anomalies, which logically supports a desired large enough $N$ for $Z_{NR}$. This mechanism effectively makes $Z_{NR}$ equal to $U(1)_{R}$ and thus offers a logically complete solution to the axion quality problem.

Hyperglycaemia is Associated with Male Infertility and Activin Dysregulation in Type 1 Diabetes
Creators: name: Maresch, Constanze Christin
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Type 1 diabetes mellitus is a chronic, lifelong condition with worldwide increasing incidence. Furthermore, it affects a growing number of men of reproductive age since 90 % of these patients are diagnosed before the age of 30. Numerous studies have indicated that diabetes mellitus disrupts fertility at various levels including altered spermatogenesis, degenerative and apoptotic changes in testes, and altered glucose metabolism in Sertoli cells, but little is known about the underlying mechanisms. In the present work, the mev-1 mutant of the nematode Caenorhabditis elegans, the Ins2Akita+/- mouse model, as well as cultured Sertoli cells were used to investigate whether hyperglycaemia alters the secretory patterns and actions of the activin family of proteins.

 It was found that glucose at a concentration of 100 mM significantly reduced brood size in mev-1 nematodes. Most interestingly, diabetic Ins2Akita+/- mice showed progressive testicular disturbance, with a 30 % reduction in testis weight at 24 weeks of age, which correlated with blood glucose and HbA1c values. Diabetic mice showed significantly reduced seminiferous tubule diameters and increased spermatogenic disruption, although testes morphology appeared grossly normal. Serum LH and testosterone were similar in all groups. All Ins2Akita+/- mice showed elevation of the testicular inflammatory cytokines activin A and IL-6 at 12 and 24 weeks of age, while other key inflammatory cytokines were unaffected. Conversely, intratesticular activin B was downregulated at both time-points, while the activin regulatory proteins, follistatin and inhibin, were unchanged. At 24 weeks, activin type 2 receptor subunit expression was reduced in the diabetic mice, but Smad signalling was enhanced. Finally, investigations on in vitro cultured Sertoli cells did not show an effect of hyperglycaemia on activin A regulation or the formation of tight junctions.

 In conclusion the present work demonstrates that hyperglycaemia disrupts fertility in both mev-1 nematodes and the Ins2Akita+/- mouse model. Moreover, it was shown that prolonged exposure to elevated blood glucose in the Ins2Akita+/- mice leads to progressive testicular disruption, which may be exacerbated by dysregulation of testicular activin activity rather than by dysregulation of the hypogonadal pituitary

description: This article reviews our current understanding of how the internal quark structure of a nucleon bound in nuclei differs from that of a free nucleon. We focus on the interpretation of measurements of the EMC effect for valence quarks, a reduction in the Deep Inelastic Scattering (DIS) cross-section ratios for nuclei relative to deuterium, and its possible connection to nucleon-nucleon Short-Range Correlations (SRC) in nuclei. Our review and new analysis (involving the amplitudes of non-nucleonic configurations in the nucleus) of the available experimental and theoretical evidence shows that there is a phenomenological relation between the EMC effect and the effects of SRC that is not an accident. The influence of strongly correlated neutron-proton pairs involving highly virtual nucleons is responsible for both effects. These correlated pairs are temporary high-density fluctuations in the nucleus in which the internal structure of the nucleons is briefly modified. This conclusion needs to be solidified by the future experiments and improved theoretical analyses that are discussed herein.

Evaluating ERP Implementation Project: The Case of on ERP Implementation, at the United Nations Economic Commission for Africa
Creators: name: Kurabachew, Fetsum

Year: 2017

description: The purpose of this study was to evaluate Enterprise Resource Planning (ERP) implementation against selected critical success factors. The implementation of Umoja, an ERP adopted recently by the UN, at the United Nations Economic Commission for Africa was evaluated against three selected critical success factors. The research focused and discovered that effective project management, change management and training are critical factors that influence successful implementation of an ERP. To address this study, a case study was employed with both quantitative and qualitative approaches. Yamane sample calculating technique was used to calculate sample size. The total sample size engaged for this study is 133 which included transactional end users of the new ERP system, Umoja, at UNECA. Regression was used to analyze the quantitative data obtained through questionnaire. Qualitative data was also analyzed. Moreover, data validity and reliability tests were also made. The findings of the study indicate that ERP implementation success at the United Nations Economic Commission for Africa when evaluated against critical success factors was not adequate as measured by the process experts of the system in the organization. The study then concluded that organizations should identify and outline critical success factors applicable in their area of expertise for implementing ERP successfully. The study recommended improvements in the areas of project management, change management and training be made in the organization to continue the successful utilization of the ERP as well as for future related project implementations of Umoja. In addition, the study directed future works to be conducted on Critical Success Factors not covered in the study as well as ERP implementations in big organizations

description: Based on first-principles calculations, an antiferromagnetic Ising model on a triangular lattice has been proposed to interpret the order of Fe$(1)$-Ge pairs and the formation of $\sqrt{3}$ $\times $ $\sqrt{3}$ superstructures in the Fe$_5$GeTe$_2$ (F5GT), as well as to predict the existence of similar superstructures in Ni doped F5GT (Ni-F5GT). Our study suggests that F5GT systems may be considered as a structural realization of the well known antiferromagnetic Ising model on a triangular lattice. Based on the superstructures, a Heisenberg-Landau Hamiltonian, taking into account both Heisenberg interactions and longitudinal spin fluctuations, is implemented to describe magnetism in both F5GT and Ni-F5GT. We unveil that frustrated magnetic interactions associated with Fe(1), tuned by a tiny Ni doping ($x \leq 0.2 $), is responsible for the experimentally observed enhancement of the $T_c$ to 478 K in Ni-F5GT. Our calculations show that at low doping levels, monolayer Ni-F5GT has almost the same magnetic phase diagram as that of the bulk, which indicates a pervasive beyond room temperature ferromagnetism in this Ni doped two-dimensional system.

description: This thesis represents a series of papers that cover the spectrum of managing survivors of stroke after discharge into the community. Specifically, this research was aimed at determining the benefits of policy and practice options already existing in the Australian health care system for the long-term management of stroke. The major themes of this thesis include managing risk factors after a stroke, improving knowledge of prevention strategies in survivors, and managing unmet needs after a stroke. Evidence from this thesis could help inform policy and practice decisions on how to better support people with stroke in the community.

The fate of the critical endpoint at large $N_c$

description: The phase diagram of QCD is investigated by varying number of colors $N_c$ within a Polyakov loop quark-meson chiral model. In particular, our attention is focused on the critical point(s): the critical point present for $N_c=3$ moves toward the $μ_q$-axis and disappears as soon as the number of color is increased. Yet, a distinct critical point emerges along the temperature axis for $N_c = 53$ and moves toward finite density when increasing $N_c$ further. Thus, the phase diagram at large $N_c$ looks specular w.r.t. the $N_c = 3$ results, with the first order transition in the upper-left and crossover in the down-right regions of the the $(μ_q,T)$-plane. The pressure is also evaluated in dependence of $N_c$, showing a scaling with $N_c^0$ in the confined and chirally broken phase and with $N_c^2$ in the deconfined one. Moreover, the presence of a chirally symmetric but confined `quarkyonic phase' at large density and moderate temperature with a pressure proportional to $N_c$ is confirmed.

description: International Financial Reporting Standard (IFRS) are set of accounting standard developed by IASB that is becoming the global standard for the preparation of public company financial statements. The aim of this study was to examine Factors Influencing Successful Implementation of IFRS Project in Commercial Bank of Ethiopia. These researches sought to achieve five specific objectives with the key variables examined being the dependent variable successful implementation of IFRS project in CBE and independent variables of top management support, organization structure, communication system, team building and Monitoring and Evaluation. To answer research questions and test the hypothesis the researcher adopted primary and secondary source of data. The primary data were collected through questionnaires and interview. Whereas, the secondary source of data was collected from publication, Previous research and consultant printed document. The researcher implemented both qualitative and quantitative (mixed) research approach. The questionnaire data were analysed using descriptive statistics, correlations, and multiple linear regression analysis and data from interview was triangulated with the descriptive part of analysis. The results have shown that with Pearson correlation result of 0.383, 0.387, 0.327 and 0.418 for the independent variable of Top Management Support, Organizational Structure, Communication System and Team building respectively have weak positive association with the dependent variable of Successful implementation of IFRS project in CBE. While monitoring and evaluation has strong positive relationship with dependent variable with Pearson Correlation of 0.678. The results of multiple regressions revealed that Top Management Support, Organizational Structure, Communication System and Team Building have insignificant effect on successful implementation of IFRS project. However, Effective Monitoring and Evaluation has a positive and significant effect on successful implementation of IFRS project in CBE. Finally, the researcher provides related recommendations which were associated with the study findings and suggest further study on the issue.
A reverse genetics approach for the analysis of tetraspanin CD82

Subjects: subject: 110799 Immunology not elsewhere classified
subject: FOS: Clinical medicine

description: CD82 is a protein found on the surface of most cells in the body, including cells of the immune system. CD82 is well known from cancer studies, as it controls how cancer cells migrate from one part of the body to another, but what CD82 does normally in the immune system is poorly understood. I discovered that CD82 is critical for a healthy immune system as it controls inflammation and is needed to start an immune response. In the future CD82 may be a target to help treat not only cancer but diseases of the immune system such as inflammation.
Mixed methods research approaches to measuring organisational culture

subject: Organisational behaviour

description: The focus of this chapter is the use of MMR in measuring organisational culture. Firstly, we look at the many definitions that have developed over the last two decades as to what MMR is and what it is not. We then overview the methodological continuum which assists in contextualising methodological approaches in a range that at one end of the continuum are mono methods, followed by variations of multi-methods, then mixed methods and mixed models at the opposite end of the continuum. The purposes of utilising MMR approaches is presented before exploring the use of MMR across a variety of management disciplines and sub disciplines. The suitability of MMR to studies investigating aspects of organisational culture is also discussed before applying dimensions of a set of quality criteria to the good reporting of MMR studies to a selection of six published articles which utilise MMR approaches to the study of organisational culture.
Anderson-Mott transition in a disordered Hubbard model with correlated hopping

description: We study the ground state phase diagram of the Anderson-Hubbard model with correlated hopping at half filling in one-dimension. The Hamiltonian has a local Coulomb repulsion $U$ and a disorder potential with local energies randomly distributed in the interval $(-W,+W)$ with equal probability, acting on the singly occupied sites. The hopping process which modifies the number of doubly occupied sites is forbidden. The hopping between nearest-neighbor singly occupied and empty sites or between singly occupied and doubly occupied sites have the same amplitude $t$. We identify three different phases as functions of the disorder amplitude $W$ and Coulomb interaction strength $U>0$. When $U<4t$ the system shows a metallic phase (i) only when no disorder is present $W=0$ or an Anderson-localized phase (ii) when disorder is introduced $W\neq 0$. When $U>4t$ the Anderson-localized phase survives as long as disorder effects dominates on the interaction effects, otherwise a Mott insulator phase (iii) arises. The phases (i) and (ii) are characterized by a finite density of doublons and a vanishing charge gap between the ground state and the excited states. The phase (iii) is characterized by vanishing density of doublons and a finite gap for the charge excitations.

description: The low-temperature quasi-universal behavior of amorphous solids has been attributed to the existence of spatially-localized tunneling defects found in the low-energy regions of the potential energy landscape. Computational models of glasses can be studied to elucidate the microscopic nature of these defects. Recent simulation work has demonstrated the means of generating stable glassy configurations for models that mimic metallic glasses using the swap Monte Carlo algorithm. Building on these studies, we present an extensive exploration of the glassy metabasins of the potential energy landscape of a variant of the most widely used model of metallic glasses. We carefully identify tunneling defects and reveal their depletion with increased glass stability. The density of tunneling defects near the experimental glass transition temperature appears to be in good agreement with experimental measurements.
