subject: Clinical pharmacy and pharmacy practice

description: This thesis explores and describes the history of professional entry-level pharmacy education and its relationship to contemporary pharmacy practice in Queensland, in consequence of the transition from an Apprenticeship based training scheme to a university based Bachelor of Pharmacy Degree course in 1960. In so doing, particular reference is made to the development of pharmacy practice in Rockhampton, a major Central Queensland regional centre. The review program is undertaken within a broad historical background eliciting the changing role of pharmacy from historical arcane craft to complex science. Firstly, the evolution of pharmacy practice in Great Britain as the progenitor of Australian pharmacy is mapped; secondly, aspects of pre-degree pharmacy practice and education in Australia are explored; thirdly, the transition era spanning the advocacy, establishment, progression and consolidation of a pharmacy degree course at the University of Queensland is traversed by means of the retrospective perceptions of contemporary students in the light of their subsequent career path experiences. Influences on the replacement of an apprenticeship education in Queensland by a university degree are examined and the sometimes conflicting demands of contemporary education philosophies and professional practice realities are investigated. Refinements in educational philosophy and its implementation during the maturing phases of the degree course are charted and changes appraised during a time span over which the essential and recognisable elements of modern pharmaceutical practice and education strategy became manifest. The academic peaks and troughs of the new educational format in the context of contemporary practice are discussed and from them are derived conclusions for the further successful consolidation of multidisciplinary healthcare education and practice. The incursion of pharmacy practice into the domain of acute patient care in private hospitals - formerly the almost exclusive prerogative of medical and nursing personnel - is investigated through a regional case study. The local acceptance of clinical pharmacy by members of the health care team is evaluated and implications for practice are considered.

description: The thermoelectric properties and electronic band structures for Se-doped Co3SnInS2 were examined. The parent compound of this material (Co3Sn2S2) has two kinds of Sn sites (Sn1 and Sn2 sites). The density functional theory (DFT) calculations show that the indium substitution at the Sn2 site induces a metallic band structure, on the other hand, a semiconducting band structure is obtained from substitution at the Sn1 site. However, according to the previous reports, since the indium atom prefers to replace the tin atom at the Sn1 site rather than the Sn2 site, the resistivity of Co3SnInS2 shows semiconducting-like behavior. In this study we have demonstrated that metallic behavior and a decrease in resistivity for Se-doped Co3SnInS2 occurs without suppression of the Seebeck coefficient. From the DFT calculations, when the selenium content is above 0.5, the total crystallographic energy shows that a higher indium occupancy at Sn2 site is more stable. Therefore, it is suggested that the selenium doping suppress the site preference for indium substitution. This is one of the possible explanations for the metallic conductivity observed in Se-doped Co3SnInS2

description: Switching describes a composite set of related behaviours engaged in by customers when they replace or exchange a service provider. This behaviour is dynamic and muti-dimensional. In much of the previous switching research, these qualities have gone unrecognised. A sophisticated holistic account of customer service switching behaviour provides better insights into the management of customer/provider relationships, thereby providing a strategic opportunity for service businesses to increase their market share and profitability.

description: We revisit the framework of axion-like inflation in view of the possibility that the coupling of the inflaton to a non-Abelian topological charge density could lead to the generation of a rapidly thermalizing heat bath. Both dispersive (mass) and absorptive (friction) effects are included. For phenomenologically viable parameters, the system remains in a weak regime of warm inflation (thermal friction $\ll$ Hubble rate). For tensor perturbations we derive an interpolating formula that incorporates both vacuum and thermal production. The latter yields a model-independent frequency shape $\sim f_0^3$ in the LISA window, whose coefficient allows to measure the maximal shear viscosity of the thermal epoch. It is a challenge, however, to find models where the coefficient is large enough to be observable.

A case of career transitioning: From trade to teacher

Subjects: classificationCode: 390307
subject: Teacher education and professional development of educators

description: "This study investigated the lived experiences of a group of tradespersons who completed a teacher education program and career transitioned into secondary school teaching. Although specific trade entry pathways into initial secondary teacher education programs have been delivered by Australian Universities since the late 1990s, there has been limited research and data on graduates’ achievements as teachers and the roles they currently play within secondary schools. The 16 participants in this study were graduates from an Australian University, five to ten years post-graduation with dual qualifications to teach Technology and Vocational Education and Training (VET) programs in Secondary schools. The study identified the key motivations that impacted on their decision to become a technology teacher in secondary schools and the significant junctures throughout their transition that influenced the creation of their teacher identity. Descriptive, interpretative case study method was used for the study. Data were collected from the university’s archival student records. The primary source of evidence was interview. Thematic analysis was used to construct discursive interpretations of the meanings of participants’ career transitions. Through such analyses, trades to teacher discourses focussed on notions of identity and borderland discourse. The study found that career transition from trade to teacher is characterised by three borderland discourses: cracking the codes, street cred and fusing school and the real world. The significance of the findings is that these borderland discourses work in harmony throughout the experiences of career transition to create a hybrid technology teacher identity. This hybridity captures participants’ identities and experiences as they fused the worlds of trade and school through an initial teacher education program. The development of a strong personal pedagogy was an outcome of traversing the borderlands between a tradesperson and teacher. The findings have implications for the design and delivery of trade entry initial teacher education programs, and for the recruitment and retention of such teachers by employing authorities within the context of secondary schooling."--Abstract.
Socio-technical analysis of railway level crossing design for pedestrian use
Creators: name: Spiryagina, Mayya
Publisher: name: CQUniversity
Year: 2023
Subjects: classificationCode: 350505
subject: Occupational and workplace health and safety

description: Contemporary research acknowledges the negative contributions of human factors in rail accident statistics. A subset of that relates to the safety of pedestrians at level crossings. Traditionally, the improvement of new or existing pedestrian level crossings has been done based on different design solutions and operational techniques, the subsequent performance of which has then been confirmed or otherwise in post installation commissioning or subsequent operations. However, the focus of the evaluation often lacks any human factors design/engineering focus. There are human factors design issues as well as pedestrian errors and violations which need to be assessed to identify their associated risks, predict their likely outcomes and determine possible prevention measures to minimise their potential for harm. In this thesis, the modification of existing safety management systems by means of an application of three common economic techniques (risk cost- benefit analysis, return on investment and return on prevention investment) for four types of pedestrian railway crossings with the introduction of one human behaviour factor are described. Based on the results obtained from the investigation process with the developed methodology, the discussion has been performed and recommendations stated.

description: We present analytically exact results to show that, certain quasi one-dimensional lattices where the building blocks are arranged in a random fashion, can have an absolutely continuous part in the energy spectrum when special correlations are introduced among some of the parameters describing the corresponding Hamiltonians. We explicitly work out two prototype cases, one being a disordered array of a simple diamond network and isolated dots, and the other an array of triangular plaquettes and dots. In the latter case, a magnetic flux threading each plaquette plays a crucial role in converting the energy spectrum into an absolutely continuous one. A flux controlled enhancement in the electronic transport is an interesting observation in the triangle-dot system that may be useful while considering prospective devices. The analytical findings are comprehensively supported by extensive numerical calculations of the density of states and transmission coefficient in each case.

description: Numerical approaches to the correlated electron problem have achieved considerable success, yet are still constrained by several bottlenecks, including high order polynomial or exponential scaling in system size, long autocorrelation times, challenges in recognizing novel phases, and the Fermion sign problem. Methods in machine learning (ML), artificial intelligence, and data science promise to help address these limitations and open up a new frontier in strongly correlated quantum system simulations. In this paper, we review some of the progress in this area. We begin by examining these approaches in the context of classical models, where their underpinnings and application can be easily illustrated and benchmarked. We then discuss cases where ML methods have enabled scientific discovery. Finally, we will examine their applications in accelerating model solutions in state-of-the-art quantum many-body methods like quantum Monte Carlo and discuss potential future research directions.

description: This year marks 50 years since the launch of one of Australia’s first major conservation battles, waged against Queensland’s ultra-conservative, pro-development premier Joh Bjelke-Petersen. It was for a location few had ever heard of – Cooloola, an area that stretches from Noosa to Rainbow Beach, around 70 km north. The unlikely leader of this campaign was a wildflower painter named Kathleen McArthur, who led the Caloundra branch of an environmental group the Australian newspaper called “the most militant of conservation cells”. Kathleen, together with colleagues such as poet Judith Wright, pioneered and honed activist strategies that are still instructive today. She understood art’s ability to prompt human emotion and marshal the public support required to bring about change.

description: For gradiometric three-Josephson-junction flux qubits, we perform a systematic study on the tuning of the minimal transition frequency, the so-called qubit gap. By replacing one of the qubit's Josephson junctions by a dc SQUID, the critical current of this SQUID and, in turn, the qubit gap can be tuned in situ by a control flux threading the SQUID loop. We present spectroscopic measurements demonstrating a well-defined controllability of the qubit gap between zero and more than 10 GHz. In the future, this enables one to tune the qubit into and out of resonance with other superconducting quantum circuits, while operating the qubit at its symmetry point with optimal dephasing properties. The experimental data agree very well with model calculations based on the full qubit Hamiltonian. From a numerical fit, we determine the Josephson coupling and the charging energies of the qubit junctions. The derived values agree well with those measured for other junctions fabricated on the same chip. We also demonstrate the biasing of gradiometric flux qubits near the symmetry point by trapping an odd number of flux quanta in the gradiometer loop. In this way, we study the effect of the significant kinetic inductance, thereby obtaining valuable information for the qubit design.

description: Multiple choice questions (MCQs) are widely used in digital learning systems, as they allow for automating the assessment process. However, due to the increased digital literacy of students and the advent of social media platforms, MCQ tests are widely shared online, and teachers are continuously challenged to create new questions, which is an expensive and time-consuming task. A particularly sensitive aspect of MCQ creation is to devise relevant distractors, i.e., wrong answers that are not easily identifiable as being wrong. This paper studies how a large existing set of manually created answers and distractors for questions over a variety of domains, subjects, and languages can be leveraged to help teachers in creating new MCQs, by the smart reuse of existing distractors. We built several data-driven models based on context-aware question and distractor representations, and compared them with static feature-based models. The proposed models are evaluated with automated metrics and in a realistic user test with teachers. Both automatic and human evaluations indicate that context-aware models consistently outperform a static feature-based approach. For our best-performing context-aware model, on average 3 distractors out of the 10 shown to teachers were rated as high-quality distractors. We create a performance benchmark, and make it public, to enable comparison between different approaches and to introduce a more standardized evaluation of the task. The benchmark contains a test of 298 educational questions covering multiple subjects & languages and a 77k multilingual pool of distractor vocabulary for future research.

description: We combine replica exchange (parallel tempering) with normalizing flows, a class of deep generative models. These two sampling strategies complement each other, resulting in an efficient strategy for sampling molecular systems characterized by rare events, which we call learned replica exchange (LREX). In LREX, a normalizing flow is trained to map the configurations of the fastest-mixing replica into configurations belonging to the target distribution, allowing direct exchanges between the two without the need to simulate intermediate replicas. This can significantly reduce the computational cost compared to standard replica exchange. The proposed method also offers several advantages with respect to Boltzmann generators that directly use normalizing flows to sample the target distribution. We apply LREX to some prototypical molecular dynamics systems, highlighting the improvements over previous methods.

description: The polarization states of lasers are crucial issues both for practical applications and fundamental research. In general, they depend in a combined manner on the properties of the gain material and on the structure of the electromagnetic modes. In this paper, we address this issue in the case of solid-state organic lasers, a technology which enables to vary independently gain and mode properties. Different kinds of resonators are investigated: in-plane micro-resonators with Fabry-Perot, square, pentagon, stadium, disk, and kite shapes, and external vertical resonators. The degree of polarization P is measured in each case. It is shown that although TE modes prevail generally (P>0), kite-shaped micro-laser generates negative values for P, i.e. a flip of the dominant polarization which becomes mostly TM polarized. We at last investigated two degrees of freedom that are available to tailor the polarization of organic lasers, in addition to the pump polarization and the resonator geometry: upon using resonant energy transfer (RET) or upon pumping the laser dye to an higher excited state. We then demonstrate that significantly lower P factors can be obtained.

description: We analyze both the early and late time radio and X-ray data of the tidal disruption event Swift J1644+57. The data at early times ($\lesssim 5$ days) necessitates separation of the radio and X-ray emission regions, either spatially or in velocity space. This leads us to suggest a two component jet model, in which the inner jet is initially relativistic with Lorentz factor $Γ\approx 15$, while the outer jet is trans-relativistic, with $Γ\lesssim 1.2$. This model enables a self-consistent interpretation of the late time radio data, both in terms of peak frequency and flux. We solve the dynamics, radiative cooling and expected radiation from both jet components. We show that while during the first month synchrotron emission from the outer jet dominates the radio emission, at later times radiation from ambient gas collected by the inner jet dominates. This provides a natural explanation to the observed re-brightening, without the need for late time inner engine activity. After 100 days, the radio emission peak is in the optically thick regime, leading to a decay of both the flux and peak frequency at later times. Our model's predictions for the evolution of radio emission in jetted tidal disruption events can be tested by future observations.

Phytocapping of municipal landfills: Evaluating the performance of 21 tree species and two soil depths

description: "Capping is a mandatory landfill closure procedure to isolate the waste from outside environment, mainly rain water. Clay caps are mostly expensive and often fail to limit entry of water into the waste by developing cracks due to desiccation. To reduce capping costs and to increase environmental benefits, an alternate capping system called ‘Phytocapping’ was trialled at Lakes Creek Road Landfill, Rockhampton, Australia. This system consists of a soil cover and vegetation. Soil cover stores water during rainfall events and the vegetation removes the stored water via transpiration. Trees also act as ‘rain interceptors’ by trapping certain proportion of the rainfall in their canopy. Soil and plants also contribute to reduced methane emission by supporting methanotrophs in their root zone."

description: This paper presents a novel synthesis method for designing an optimal and robust guidance law for a non-throttleable upper stage of a launch vehicle, using a convex approach. In the unperturbed scenario, a combination of lossless and successive convexification techniques is employed to formulate the guidance problem as a sequence of convex problems that yields the optimal trajectory, to be used as a reference for the design of a feedback controller, with little computational effort. Then, based on the reference state and control, a stochastic optimal control problem is defined to find a closed-loop control law that rejects random in-flight disturbance. The control is parameterized as a multiplicative feedback law; thus, only the control direction is regulated, while the magnitude corresponds to the nominal one, enabling its use for solid rocket motors. The objective of the optimization is to minimize the splash-down dispersion to ensure that the spent stage falls as close as possible to the nominal point. Thanks to an original convexification strategy, the stochastic optimal control problem can be solved in polynomial time since it reduces to a semidefinite programming problem. Numerical results assess the robustness of the stochastic controller and compare its performance with a model predictive control algorithm via extensive Monte Carlo campaigns.

description: This research looks at the controversial issue of foreign direct investment (FDI) in Libya. Global FDI usually flows from capital surplus countries towards capital deficit countries. However, Libya is a capital surplus country, yet is still requires foreign investments. Therefore, an empirical question arises: why does Libya, as a capital surplus country, have to allow FDI? This research examines this question, as well as the distribution of FDI in Libya. It considers why most FDI in Libya is concentrated on the petroleum sector, while other sectors such as education, health, transport, manufacturing, technology and trade are ignored. The complex empirical field for this study requires close examination of the economic policies of FDI that are issued by the Libyan government. This study also examines the pattern and distribution of FDI in Libya during the international economic sanctions and following the recent removal of these sanctions, from 1992 to 2010.

description: We generalize Einstein's General Relativity (GR) by assuming that all matter (including macro-objects) has quantum effects. An appropriate theory to fulfill this task is Gauge Theory Gravity (GTG) developed by the Cambridge group. GTG is a ``spin-torsion" theory, according to which, gravitational effects are described by a pair of gauge fields defined over a flat Minkowski background spacetime. The matter content is completely described by the Dirac spinor field, and the quantum effects of matter are identified as the spin tensor derived from the spinor field. The existence of the spin of matter results in the torsion field defined over spacetime. Torsion field plays the role of Bohmian quantum potential which turns out to be a kind of repulsive force as opposed to the gravitational potential which is attractive. The equivalence principle remains and essential in this theory so that GR is relegated to a locally approximate theory wherein the quantum effects (torsion) are negligible. As a toy model, we assume that the macro matter content can be described by the covariant Dirac equation and apply this theory to the simplest radially symmetric and static gravitational systems. Consequently, by virtue of the cosmological principle, we are led to a static universe model in which the Hubble redshifts arise from the torsion fields.

description: Masses of the ground and excited (1P, 2S, 1D, 2P, 3S) states of the fully-heavy tetraquarks, composed of charm ($c$) and bottom ($b$) quarks and antiquarks, are calculated in the diquark-antidiquark picture within the relativistic quark model based on the quasipotential approach and quantum chromodynamics. The quasipotentials of the quark-quark and diquark-antidiquark interactions are constructed similarly to the previous consideration of mesons and baryons. Relativistic effects are consistently taken into account. A tetraquark is considered as a bound state of a diquark and an antidiquark. The finite size of the diquark is taken into account, using the form factors of the diquark-gluon interaction. It is shown that most of the investigated states of tetraquarks lie above the decay thresholds into a meson pair, as a result they can be observed only as broad resonances. The narrow state X(6900) recently discovered in the di-$J/ψ$ production spectrum by the LHCb, CMS and ATLAS Collaborations corresponds to an excited state of the fully-charmed tetraquark. Other recently discovered exotic heavy resonances X(6200), X(6400), X(6600), X(7200), X(7300) can also be interpreted as the different excitations of the fully-charmed tetraquark.

description: Park et al. [Phys. Rev. A 106, L031504 (2022)] showed that the Shannon entropy of the probability distribution of a single random variable for far-field profiles (FFPs) in deformed microcavity lasers can efficiently measure the directionality of deformed microcavity lasers. In this study, we instead consider two random variables of FFPs with joint probability distributions and introduce the decomposed (Shannon) entropy for the peak intensity of directional emissions. This provides a new foundation such that the decomposed entropy can estimate the degree of the output power at given FFPs without any further information.

description: Edge engineering is important for both fundamental research and applications as the device size decreases to nanometer scale. This is especially the case for graphene because a graphene edge shows totally different electronic properties depending on the atomic structure and the termination. It has recently been shown that an atomically precise zigzag edge can be obtained by etching graphene and graphite using hydrogen (H) plasma. However, edge termination had not been studied directly. In this study, termination of edges created by H-plasma is studied by high-resolution electron energy loss spectroscopy (HREELS) to show that the edge is $\mathrm{sp}^{2}$ bonded and the edge carbon atom is terminated by only one H atom. This suggests that an ideal zigzag edge, which is not only atomically precise but also $\mathrm{sp}^{2}$ bonding, can be obtained by H-plasma etching. Etching of the graphite surface with plasma of a different isotope, deuterium (D), is also studied by scanning tunneling microscopy (STM) to show that D-plasma anisotropically etches graphite less efficiently, although it can make defects more efficiently, than H-plasma.

description: In this research, by responding to users' utterances with multiple replies to create a group chat atmosphere, we alleviate the problem that Natural Language Generation chatbots might reply with inappropriate content, thus causing a bad user experience. Because according to our findings, users tend to pay attention to appropriate replies and ignore inappropriate replies. We conducted a 2 (single reply vs. five replies) x 2 (anonymous avatar vs. anime avatar) repeated measures experiment to compare the chatting experience in different conditions. The result shows that users will have a better chatting experience when receiving multiple replies at once from the NLG model compared to the single reply. Furthermore, according to the effect size of our result, to improve the chatting experience for NLG chatbots which is single reply and anonymous avatar, providing five replies will have more benefits than setting an anime avatar.

subject: Aquaculture

description: This thesis concerns a strategy to assure the future viability of the frog farming industry in Tien Giang province and Ho Chi Minh City, Vietnam. Privately operated frog farms are a relatively recent phenomenon in Vietnam with the potential to make a significant contribution to the Vietnamese economy and poverty reduction. Frog meat export (especially to China) is a potential growth export industry for Vietnam. However, frog farmers in Tien Giang province and Ho Chi Minh City, Vietnam, face various risks but lack frog farming quality standards and risk management strategies to overcome these. This thesis identifies the production, market, political risks and environmental risks facing Vietnamese frog farmers. These are sub-categorized according to eight key issues for research: site location, species farmed, brood stock, farming techniques, disease, price fluctuations and government regulation. The thesis employs qualitative research founded on a constructivist interpretivist paradigm. The context of the research is Tien Giang Province and Ho Chi Minh City in southern Vietnam. An evaluative framework is established to conduct interviews a sample of eighteen frog farmers, four frog dealers, seven government officials and four agricultural university academics in the selected locale. The research outcomes reveal that frog farming of the sample researched in the main is typified by ad hoc site selection, poor quality species selection and brood stock, ill-informed farming techniques and disease management, environmental pollution, uncoordinated and corrupt market practices, and risk to consumer health and safety. In short, there is minimal government control or regulation of the frog farming industry investigated. The research elicits forty-eight risks facing frog farming in the research sample. These risks are structured into quality standards and a risk management strategy towards the adoption of industry certification ecolabelling as defined by the Fisheries and Aquaculture Organization of the United Nations in order to assure the future viability of frog farming in Tien Giang province and Ho Chi Minh City, Vietnam.
