Workplace injuries are a significant issue in the health care sector, where Allied Health professionals are an important and diverse sub‐set. Knowledge about Allied Health professionals’ workplace injuries varies by individual occupational group, and some groups, including Prosthetists/Orthotists have not previously been researched. This thesis aims to address this knowledge gap through five studies, with the overarching aim of identifying workplace hazards and injuries in the Australian Prosthetics/Orthotics workforce. Analysis of Australian Workers’ compensation and Labour force data for Allied Health Professionals identifying number, type and mechanism of injuries, found Prosthetists/Orthotists have the highest injury prevalence, with work‐related musculoskeletal disorders (WMSD) the most common injury type. A systematic review examining WMSD in the individual allied health professions found most research focused on Physiotherapy and Occupational Therapy. A wide range of WMSD prevalence was found across all AHP, but no research addressing the Prosthetics/Orthotics profession was identified. A qualitative exploration of the experience of work for Prosthetists/Orthotists in Australia identified a range of workplace factors reported to be hazardous, including concerns related to work design and workshop environments. A subsequent retrospective cohort study of Australian Prosthetists/Orthotists of prevalence and risk factors for WMSD found a prevalence of 80 percent of WMSD, and factors predicting these injuries including work hours and physical and psychosocial hazards. A single centre pilot study then explored physical environmental Prosthetist/Orthotist workshop exposures. While chemical exposures were negligible, noise levels were excessive and required workplace redesign and personal protective equipment to prevent related injuries and illnesses. The findings of this research demonstrate that Prosthetists/Orthotists in Australia work in environments that are likely to be hazardous. They have a high prevalence of WMSD and are exposed to a variety of unique workplace physical, psychosocial and environmental hazards which require specifically targeted prevention strategies. Further research is required to understand the causation of injuries and explore the development and implementation of appropriate controls.

description: Single-field slow-roll inflation predicts a nearly scale-free power spectrum of perturbations, as observed at the scales accessible to current cosmological experiments. This spectrum is slightly red, showing a tilt $(1-n_s)\sim 0.04$. A direct consequence of this tilt are nonvanishing runnings $α_s=\mathrm d n_s/\mathrm d\log k$, and $β_s=\mathrm dα_s/\mathrm d\log k$, which in the minimal inflationary scenario should reach absolute values of $10^{-3}$ and $10^{-5}$, respectively. In this work we calculate how well future surveys can measure these two runnings. We consider a Stage-4 (S4) CMB experiment and show that it will be able to detect significant deviations from the inflationary prediction for $α_s$, although not for $β_s$. Adding to the S4 CMB experiment the information from a WFIRST-like or a DESI-like survey improves the sensitivity to the runnings by $\sim$ 20\%, and 30\%, respectively. A spectroscopic survey with a billion objects, such as the SKA, will add enough information to the S4 measurements to allow a detection of $α_s=10^{-3}$, required to probe the single-field slow-roll inflationary paradigm. We show that only a very-futuristic interferometer targeting the dark ages will be capable of measuring the minimal inflationary prediction for $β_s$. The results of other probes, such as a stochastic background of gravitational waves observable by LIGO, the Ly-$α$ forest, and spectral distortions, are shown for comparison. Finally, we study the claims that large values of $β_s$, if extrapolated to the smallest scales, can produce primordial black holes of tens of solar masses, which we show to be easily testable by the S4 CMB experiment.

description: We carry out investigations of inverted crossover resonances in $π$-driven four-level systems where $ΔF$ can be zero. Through the use of sub-Doppler frequency modulation spectroscopy of the $(6s^{2})$ $^{1}S_{0}$ $-$ $(6s6p)$ $^{3}P_{1}$ transition in $^{171}$Yb the resonance becomes manifest. The centre-frequency is inherently insensitive to first-order Zeeman shifts and equates to the two-level resonance frequency in the absence of a magnetic field. A rate equation model is used to help validate the nature of the resonance. Optical frequency measurements of the $F'=1/2$ hyperfine line recorded over two months demonstrate a statistical uncertainty of $2\times10^{-11}$. The inverted crossover resonance found with the $F'=3/2$ line is used for 556 nm laser frequency stabilization, which is an alternative means when applied to magneto-optical trapping of $^{171}$Yb.

description: Within the framework of an eternal inflationary scenario, a natural question regarding the production of eternal bubbles is the essential condition requires to have a universe capable of generating life. In either an open or a closed universe, we find an anthropic lower bound on the amount of e-folding in the order of $60$ for the inflationary epoch, which results in the formation of large-scale structures in both linear and non-linear regimes. We extend the question of the initial condition of the universe to the sufficient condition in which we have enough initial dark matter and baryonic matter asymmetry in the early universe for the formation of galactic halos, stars, planets and consequently life. We show that the probability of a habitable universe is proportional to the asymmetry of dark matter and baryonic matter, while the cosmic budget of baryonic matter is limited by the astrophysical constrains.

description: We explore data reduction and correction steps and processed data reproducibility in the emerging single crystal total scattering based technique of three-dimensional differential atomic pair distribution function (3D-$Δ$PDF) analysis. All steps from sample measurement to data-processing are outlined in detail using a CuIr$_2$S$_4$ example crystal studied in a setup equipped with a high-energy x-ray beam and a flat panel area detector. Computational overhead as it pertains to data-sampling and the associated data processing steps is also discussed. Various aspects of the final 3D-$Δ$PDF reproducibility are explicitly tested by varying data-processing order and included steps, and by carrying out a crystal-to-crystal data comparison. We identify situations in which the 3D-$Δ$PDF is robust, and caution against a few particular cases which can lead to inconsistent 3D-$Δ$PDFs. Although not all the approaches applied here-in will be valid across all systems, and a more in-depth analysis of some of the effects of the data processing steps may still needed, the methods collected here-in represent the start of a more systematic discussion about data processing and corrections in this field.

As a mild extension of previous results we present existence statements on periodic Reeb orbits on contact manifolds with suitable supporting open books.

description: The study evaluated the challenges and benefits in the adoption and development of E-banking technology in the Commercial Bank of Ethiopia. Population of the study consist of employees of 4 branches of the CBE. The study was conducted based on the data gathered from 4 CBE branches. The stratified sampling technique and simple random sampling technique simultaneously had been used to draw the sample from the population. The stratified sampling technique was used to categorize by district. Then by simple random sampling technique 4 branches were selected from those districts. A mixed research approach was employed to answer the research questions that emerged through the review of existing literature in respect of the E-banking technology in Commercial Bank of Ethiopia. The study statistically analyzed data obtained from the survey questionnaire. To acquire the intended information the researcher used different data collection instruments like distributing questionnaire & conducting interview. The questionnaire included both open-ended and close-ended questions. And also the research framework was developed based on organization-environment –technology framework to guide the study. The result of the study indicated that, the major challenges that the Commercial Bank of Ethiopia faces in the adoption and development of E-banking technology are: high cost of implementation of E-banking, lack of customer awareness, limitation in network infrastructure and internet related support services, low levels of computer literacy, low level of ICT infrastructure and lack of trust. The study identified operational and services benefits from adopting and developing of E-banking technology such as increase productivity, reduces paper work, reduce transaction cost, generate foreign currency, increase reliability and reducing errors as operational benefits it improves customer service, reduce long queues in banking halls, increase accessibility of the bank services, create good relation between the bank and clients and encourages price transparency as services benefits. The study recommended the bank to facilitate proper and continuous training for their employees, increasing security for E-banking products, create deep awareness about E-banking technology to the community while the government should support banking sector by facilitating sufficient ICT infrastructure development in Ethiopia

description: This research embarked upon evaluating the contribution of project life cycle management practices on the overall success of projects. The research analyzed project success from the perspective of cost, time, and quality performance, as traditionally known as the Iron Tringle; and added another project success criteria, key stakeholder's satisfaction to advance the success measurement model. The research categorized these project success measures into two groups; the first three performance measure criteria, cost, time and quality, were treated as project management success while the stakeholder's satisfaction performance was treated as project's product success. The researcher surveyed 20 projects that have been completed over the past 10 years to understand project management practices that have significantly impact on the success of projects and to investigate strategies that were adopted by Total Ethiopia S.C, the case company. The research used inferential analysis to identify significant correlation between project life cycle management stages (project initiation, planning, execution and closure) with the aforementioned project success measures. The research survey data was analyzed using IBM's SPSS 24 software where the internal validity of the questionnaire was tested using Cronbach's alpha to determine the reliability of data instruments. The researcher used ANOVA, Pearson's Correlation Coefficient and regression analysis to test the relationship between variables and to suggest alternative hypothesis. The researcher, during the course of the research had gained an understanding on the need to deepen the level of details in each of the project life cycle phases and to thoroughly understand success factors arising from the project management practices. The research concluded the project report by providing valuable recommendations to the case company and for future researchers

description: The analysis of record-breaking events is of interest in fields such as climatology, hydrology or anthropology. In connection with the record occurrence, we propose three distribution-free statistics for the changepoint detection problem. They are CUSUM-type statistics based on the upper and/or lower record indicators observed in a series. Using a version of the functional central limit theorem, we show that the CUSUM-type statistics are asymptotically Kolmogorov distributed. The main results under the null hypothesis are based on series of independent and identically distributed random variables, but a statistic to deal with series with seasonal component and serial correlation is also proposed. A Monte Carlo study of size, power and changepoint estimate has been performed. Finally, the methods are illustrated by analyzing the time series of temperatures at Madrid, Spain. The R package $\texttt{RecordTest}$ publicly available on CRAN implements the proposed methods.

The Eastern European communist and post-communist experience through the films of Bela Tarr
Creators: name: Harsan, Olivia Maria
Publisher: name: La Trobe
Year: 2023

description: This thesis argues that there is a film cycle within Hungarian filmmaker Béla Tarr’s second period films, which I have coined the ‘Communist Cycle’, that are vital portraits of communism and post-communism in Hungary, informed by Tarr’s generation’s experience during and after communism. The thesis undertakes several case studies of Tarr’s Communist Cycle in order to reveal his perception of communist and post-communist Hungary conjuring bleak imagery – deprived, gloomy characters and decaying environments plagued with perpetual rain and harsh wind. This parable of the socio-political mess that followed after the collapse of the communist regime is explored throughout Tarr’s Communist Cycle. This thesis has been structured in accordance to the progression of communism into postcommunism hence it does not discuss Tarr’s films in chronological order, instead beginning with a relentless portrait of the final years of communism in Damnation (1988) and ending with a completely deteriorated social structure in The Turin Horse (2011). Damnation portrays the apprehension of the imminent change of political administration sensed in the late 1980s. Werckmeister Harmonies (2000) depicts the transition between communism to post-communism through a collective anxiety that leads to disastrous outcomes, fuelled by fear and uncertainty of this imminent change. Satantango (1994) represents a collapsed socio-political structure in postcommunist Hungary and the deprivation that followed. The Turin Horse, the final film in the cycle, concludes Tarr’s personal narrative about the post-communist experience and, is fittingly, his last feature film. This thesis contextualizes Tarr’s Communist Cycle within the framework of an Eastern European film discourse that examines the ambiguity of the post-communist milieu as communist perspectives and attitudes from the past persisted. The central arguments of this thesis draw on the ideas of Hungarian-Romanian film scholar Ágnes Pethő, among others, specifically her identification of a characteristic in Eastern European cinema: the “present presented as past”. This thesis is also informed by personal experience through the memories of my Romanian family members who lived through communism and post-communism, so the approach of this thesis combines the personal, the critical and the analytical.

Genetic structure and variation in Negrito, Senoi and Proto-Malay ethnic groups in Malaysia

Year: 2017

description: The indigenous populations of Peninsular Malaysia also known as “Orang Asli” or “original people” are putative isolated populations which comprise approximately 0.6 percent of Malaysia. Orang Aslis are categorized based on their demographic, linguistic and phonotypical characteristics in three subgroups namely Negrito, Senoi and Proto-Malay. The objective of this project was to study genetic structure in Orang Aslis through High-density SNP genotyping and Whole Genome Sequencing (WGS) technologies, and compare them to other population Southeast Asia. The results of our study showed that Malaysian Negritos are genetically distinct from other populations in East and Southeast Asia while other Orang Asli groups such as Senoi and Proto-Malay seemed to be admixed between Negritos and East Asians. We identified a genetic affinity between Andamanese and Malaysian Negritos which may suggest an ancient link between these two groups. Our results also showed gene flow between Austro-Asiatic speaking Orang Aslis and East Asian populations. The existence gene flow between these two major genetic components provided further evidences in support of an “Early Train” hypothesis, which suggests an early migration from Indochina or southern China to mainland Southeast Asia before the “Austronesian Expansion” and after “Out of Africa’ for human dispersal in Asia. Many novel genomic variants have also been discovered from whole-genome sequencing. We also found that Negrito, MahMeri, Seletar and Jakun communities are genetically isolated making them valuable resources for medical genetics researches. Our study also suggests that conventional categorization of Orang Aslis based on linguistics and anthropological characteristics may be incorrect.

description: Efficient ordinary differential equation solvers for chemical kinetics must take into account the available thread and instruction-level parallelism of the underlying hardware, especially on many-core coprocessors, as well as the numerical efficiency. A stiff Rosenbrock and nonstiff Runge-Kutta solver are implemented using the single instruction, multiple thread (SIMT) and single instruction, multiple data (SIMD) paradigms with OpenCL. The performances of these parallel implementations were measured with three chemical kinetic models across several multicore and many-core platforms. Two runtime benchmarks were conducted to clearly determine any performance advantage offered by either method: evaluating the right-hand-side source terms in parallel, and integrating a series of constant-pressure homogeneous reactors using the Rosenbrock and Runge-Kutta solvers. The right-hand-side evaluations with SIMD parallelism on the host multicore Xeon CPU and many-core Xeon Phi co-processor performed approximately three times faster than the baseline multithreaded code. The SIMT model on the host and Phi was 13-35% slower than the baseline while the SIMT model on the GPU provided approximately the same performance as the SIMD model on the Phi. The runtimes for both ODE solvers decreased 2.5-2.7x with the SIMD implementations on the host CPU and 4.7-4.9x with the Xeon Phi coprocessor compared to the baseline parallel code. The SIMT implementations on the GPU ran 1.4-1.6 times faster than the baseline multithreaded CPU code; however, this was significantly slower than the SIMD versions on the host CPU or the Xeon Phi. The performance difference between the three platforms was attributed to thread divergence caused by the adaptive step-sizes within the ODE integrators. Analysis showed that the wider vector width of the GPU incurs a higher level of divergence than the narrower Sandy Bridge or Xeon Phi.

description: The flow of charge and entropy in solids usually depends on collisions decaying quasiparticle momentum. Hydrodynamic corrections can emerge, however, if most collisions among quasiparticles conserve momentum and the mean-free-path approaches the sample dimensions. Here, through a study of electrical and thermal transport in antimony (Sb) crystals of various sizes, we document the emergence of a two-component fluid of electrons and phonons. Lattice thermal conductivity is dominated by electron scattering down to 0.1 K and displays prominent quantum oscillations. The Dingle mobility does not vary despite an order-of-magnitude change in transport mobility. The Bloch-Grüneisen behavior of electrical resistivity is suddenly aborted below 15 K and replaced by a quadratic temperature dependence. At Kelvin temperature range, the phonon scattering time and the electron-electron scattering time display a similar amplitude and temperature dependence. Taken together, the results draw a consistent picture of a bi-fluid where frequent momentum-conserving collisions between electrons and phonons dominate the transport properties.

We also comment on the tensor triangular geometry of compact cellular motivic spectra, producing in particular novel field spectra in this category. We conclude with a list of questions about the structure of the tensor triangular spectrum of the stable motivic homotopy category.

description: Background: Neighborhood watch (also known as block watch, apartment watch, home watch and community watch) grew out of a movement in the US during the late 1960s that promoted greater involvement of citizens in the prevention of crime. Since then, interest in neighborhood watch has grown considerably and recent estimates suggest that over a quarter of the UK population and over forty per cent of the US population live in areas covered by neighborhood watch schemes. Objectives: The primary aim of this review is to assess the effectiveness of neighborhood watch in reducing crime.

description: Every convex homogeneous polynomial (or form) is nonnegative. Blekherman has shown that there exist convex forms that are not sums of squares via a nonconstructive argument. We provide an explicit example of a convex form of degree four in 272 variables that is not a sum of squares. The form is related to the Cauchy-Schwarz inequality over the octonions. The proof uses symmetry reduction together with the fact (due to Blekherman) that forms of even degree, that are near-constant on the unit sphere, are convex. Using this same connection, we obtain improved bounds on the approximation quality achieved by the basic sum-of-squares relaxation for optimizing quaternary quartic forms on the sphere.

description: Using conservation of energy - a fundamental property of closed classical and quantum mechanical systems - we develop an efficient gradient-domain machine learning (GDML) approach to construct accurate molecular force fields using a restricted number of samples from ab initio molecular dynamics (AIMD) trajectories. The GDML implementation is able to reproduce global potential energy surfaces of intermediate-sized molecules with an accuracy of 0.3 kcal $\text{mol}^{-1}$ for energies and 1 kcal $\text{mol}^{-1}$ $\textÅ^{-1}$ for atomic forces using only 1000 conformational geometries for training. We demonstrate this accuracy for AIMD trajectories of molecules, including benzene, toluene, naphthalene, ethanol, uracil, and aspirin. The challenge of constructing conservative force fields is accomplished in our work by learning in a Hilbert space of vector-valued functions that obey the law of energy conservation. The GDML approach enables quantitative molecular dynamics simulations for molecules at a fraction of cost of explicit AIMD calculations, thereby allowing the construction of efficient force fields with the accuracy and transferability of high-level ab initio methods.

description: Iris is an established modality in biometric recognition applications including consumer electronics, e-commerce, border security, forensics, and de-duplication of identity at a national scale. In light of the expanding usage of biometric recognition, identity clash (when templates from two different people match) is an imperative factor of consideration for a system's deployment. This study explores system capacity estimation by empirically estimating the constrained capacity of an end-to-end iris recognition system (NIR systems with Daugman-based feature extraction) operating at an acceptable error rate i.e. the number of subjects a system can resolve before encountering an error. We study the impact of six system parameters on an iris recognition system's constrained capacity -- number of enrolled identities, image quality, template dimension, random feature elimination, filter resolution, and system operating point. In our assessment, we analyzed 13.2 million comparisons from 5158 unique identities for each of 24 different system configurations. This work provides a framework to better understand iris recognition system capacity as a function of biometric system configurations beyond the operating point, for large-scale applications.
Assessing Project Management Practices Of Prepaid Energy Metering Project In Ethiopian Electric Utility: The Case Of Addis Ababa

description: Project management systems are considered dynamic systems, similar to those in nature, which means they change over time and are hard to predict. Project management provides a framework to help accomplish goals, reduce operational costs and ensure timely delivery of projects. Therefore, this study aimed to assess the project management practices of project initiation, planning, execution & closure phases of prepaid energy metering project in Ethiopian Electric Utility. The research approach was mixed research approach. The study adopted a descriptive survey design, and questionnaire and interview were used to collect information from 34 project engineers and interview from Ethiopian electric utility management. The data wasanalyzed by obtaining the means and standard deviations. Accordingly, the results showed a moderate level of project initiation& planning practice. However, the findings indicatedthat there is a low practice of change, risk and quality management plan. Moreover, the overall project execution practice indicated moderate level but the result also revealed low practices of acceptance, risk, change and quality management. Regarding the practice of project closure, the findings indicated that projects were not evaluated after closure and lessons learned from the projects were not disseminated. As a result, the project closure revealed low level of practice. From the findings, the study concludes that there is an inefficiency of project management practices followed within prepaid energy metering project, and these practices could be graded as moderate with respect to best practices. Therefore, the findings strongly sustain that there is a need to reinforce and develop the project management practices of prepaid energy metering projects by filling the gap between the real practices in the project and the theory.

description: Toroidal flow alone is generally thought to have important influence on tokamak edge pedestal stability, even though theory analysis often predicts merely a weak stabilizing effect of toroidal flow on the edge localized modes (ELMs) in experimental parameter regimes. For the first time, we find from two-fluid MHD calculations that such a stabilization, however, can be significantly enhanced by increasing the edge plasma density. Our finding resolves a long-standing mystery whether or how toroidal rotation can indeed have effective influence on ELMs, and explains why the ELM mitigation and suppression by toroidal rotation are more favorably achieved in higher collisionality regime in recent experiments. The finding suggests a new control scheme on modulating toroidal flow stabilization of ELMs with plasma density, along with a new additional constraint on the optimal level of plasma density for the desired edge plasma conditions.

description: This is the first of two papers devoted to the asymptotic structure of space-time in the presence of a non-negative cosmological constant $Λ$. This first paper is concerned with the case of $Λ=0$. Our approach is fully based on the tidal nature of the gravitational field and therefore on the `tidal energies' built with the Weyl curvature. In particular, we use the (radiant) asymptotic supermomenta computed from the rescaled Weyl tensor at infinity to provide a novel characterisation of radiation escaping from, or entering into, the space-time. Our new criterion is easy to implement and shown to be fully equivalent to the classical one based on the news tensor. One of its virtues is that its formulation can be easily adapted to the case with $Λ>0$ covered in the second paper. We derive the general energy-momentum-loss formulae including the matter terms and all factors associated to the choices of arbitrary foliation and of super-translation. We also revisit and present a full reformulation of the traditional peeling behaviour with a neat geometrical construction that leads, in particular, to an asymptotic alignment of the supermomenta in accordance with the radiation criterion.

description: This is the second of two papers that study the asymptotic structure of space-times with a non-negative cosmological constant $Λ$. This paper deals with the case $Λ>0$. Our approach is founded on the `tidal energies' built with the Weyl curvature and, specifically, we use the asymptotic super-Poynting vector computed from the rescaled Bel-Robinson tensor at infinity to provide a covariant, gauge-invariant, criterion for the existence, or absence, of gravitational radiation at infinity. The fundamental idea we put forward is that the physical asymptotic properties are encoded in $(\scri,h_{ab},D_{ab})$, where the first element of the triplet is a 3-dimensional manifold, the second is a representative of a conformal class of Riemannian metrics on $\scri$, and the third element is a traceless symmetric tensor field on $\scri$. We similarly propose a no-incoming radiation criterion based also on the triplet $(\scri,h_{ab},D_{ab})$ and on radiant supermomenta deduced from the rescaled Bel-Robinson tensor too. We search for news tensors and argue that any news-like object must be associated to, and depends on, 2-dimensional cross-sections of $\scri$. We identify one component of news for every such cross-section and present a general strategy to find the second component. We also introduce the concept of equipped $\scri$, consider the limit $Λ\rightarrow 0$ and apply all our results to selected exact solutions of Einstein Field Equations. The full-length abstract is available in the paper.

description: We report on the nonequilibrium dynamics of the electronic structure of the layered semiconductor Ta$_2$NiSe$_5$ investigated by time- and angle-resolved photoelectron spectroscopy. We show that below the critical excitation density of $F_{C} = 0.2$ mJ cm$^{-2}$, the band gap $narrows$ transiently, while it is $enhanced$ above $F_{C}$. Hartree-Fock calculations reveal that this effect can be explained by the presence of the low-temperature excitonic insulator phase of Ta$_2$NiSe$_5$, whose order parameter is connected to the gap size. This work demonstrates the ability to manipulate the band gap of Ta$_2$NiSe$_5$ with light on the femtosecond time scale.
