The study of resilience within rural general practitioners
Creators: name: Aitken, P
Publisher: name: University Of Tasmania
Year: 2023

description: Australia is facing a dilemma with regard to sustaining a rural General Practitioner workforce. The higher workloads and longer hours associated with rural practice, combined with less hospital and specialist support in comparison to urban settings, discourage medical graduates from taking up rural practice. In order to gain an understanding of what contributes to the successful rural doctor experience, the present study explored the subjective experience of ten General Practitioners in rural North West Tasmania who have been peer-nominated as functioning in a resilient manner. The research investigated psychological wellbeing and wellness promotion practices through a mixed methodology of phenomenological qualitative research and psychological measures. The quantitative results conveyed that the participants were as resilient and mindful as the general population, with the qualitative data revealing a model of resilience incorporating the domains of positive belief systems, proactive behaviour, personality attributes, connectedness and positive affect. It was found that a superordinate paradigm of positivity provided a cohesive rationale for the complex interplay of positive attributes conveyed by all participants. Further research is suggested to explore the significance of positivity as a factor of resilience in rural medicine, particularly with regard to recruitment and retention of rural doctors.
The cityscape and landscape settings for the sculpture of Henry Moore
Creators: name: Wright, Carolyn Meredith
Publisher: name: University of British Columbia
Year: 2011

description: A writer may choose many points of view in considering works of art. Frequently the work of an artist is regarded purely for its own merit. Or it may be considered in relation to the work of other artists or periods. Here, the writer has chosen to consider certain sculptural works of the English artist Henry Moore in relation to the cityscape and landscape settings in which they have been placed. In order to more fully understand the works, how they relate or do not relate to their settings and what effects the settings have upon them, the thesis has been broken into several major sections which in turn have been further divided. A section dealing with Henry Moore as a man and an artist, the pattern of development which his work has taken, and a clarification of the meaning of his work is placed first in order that the reader may more fully understand the specific pieces when they are considered. This section is followed by a chapter devoted to a generalized discussion of the development of sculpture from earliest times to the present day and its various uses within cities and landscape both in the past and in the 20th century. Continuing the thesis, a number of Henry Moore's major works are discussed. The pieces are considered for their significance within the 'oeuvre' of Moore. They are also considered for their function in relationship to their setting -- cityscape or landscape. Certain of Moore's bronzes have been placed in both landscape and cityscape locations and in these cases it has been possible to consider the relative impact of the works within each type of setting. The pieces are not discussed in chronological order, but rather in the order which best suits both the subject and its setting. Those sculptures which have as their setting, the city, have been discussed first as it is in this environment that sculpture is most frequently found. Several of the pieces have both landscape and cityscape sites and thus provide the transition to the setting of pure natural landscape in which are placed other works of sculptor Henry Moore. Finally, a number of works having the exhibition space in the museum or gallery as their setting are given consideration. In a few cases the pieces are not permanently located. However, most of the works considered are in permanent collections and the landscape or cityscape settings in which they are found today are their permanent sites.
Beyond childhood cancer : Bringing primary carers into focus
Creators: name: Cox, TD
Publisher: name: University Of Tasmania
Year: 2023

description: Childhood cancer is no longer a universally fatal disease. Four out of five children diagnosed with cancer will now survive the disease due to advances in paediatric oncology in recent decades. Much social science research has focused on children and primary carers dealing with childhood cancer through the acute stages of diagnosis and treatment. Emerging data has also examined the long term health and social implications of children and young adult survivors of childhood cancer. However, primary carers of children whose cancer has abated have not been a focus of research attention. In this sociological thesis I investigate the everyday lived experiences of primary carers of children who have survived cancer in an Australian context. I look beyond the medical success story and beyond the ‚ÄövÑvªback to normal after cancer‚ÄövÑvº rhetoric by regarding childhood cancer as a significant disruption in carers‚ÄövÑvº lives. I paid particular attention to the ways in which carers constructed meaning and responded in the cancer aftermath by drawing on the symbolic interactionism perspective and a constructionist version of grounded theory. Qualitative data from 38 primary carers was conceptualised to represent a new normal. The findings illustrated how pre-cancer identities and taken-for-granted assumptions and expectations are no longer tenable. Carers responded by constructing a new sense of normality, characterised by insidious cancer memories and the knowledge that they had lost control of their child‚ÄövÑvºs life and well-being. With the abatement of cancer the carers gave new meanings to define their self and situation, and with particular front stages and back stages of interaction according to their insider or outsider audiences. They also developed new understandings of being a carer of a child in remission; by weaving together new meanings of hope and uncertainty with strategies of emphasising everyday life to mitigate the impact of cancer in their lives. The extent of child morbidities deriving from cancer treatment is the most pertinent constraint in shaping everyday life after cancer rather than cancer per se. By examining childhood cancer and its survival from the participants‚ÄövÑvº perspectives, the thesis offers understandings of health and illness as an ongoing social process that sits between the binaries of acute and chronic illness, cancer and survivorship and children and primary care. The findings offer ways to enhance current and future families impacted by childhood cancer, with policy direction to inform health and allied health professionals and cancer support services.

description: The title compound, [Ru(CO3)(η6-C 6H6){(C6H11)2P(CH 2-C10H7)}]-3CHCl3, was synthesized by carbonation of [RuCl2-(η6-C6H 6){(C6H11)2P(CH2C 10H7)}] with NaHCO3in methanol at room temperature. The RuIIatom is surrounded by a benzene ligand, a chelating carbonate group and a phosphane ligand in a piano-stool configuration. The crystal packing is consolidated by C-H⋯O and C-H⋯Cl hydrogen-bonding interactions between adjacent metal complexes and between the complexes and the solvent molecules. The asymmetric unit contains one metal complex and three chloroform solvent molecules of which only one was modelled. The estimated diffraction contributions of the other two strongly disordered chloroform solvent molecules were substracted from the observed diffraction data using the SQUEEZE procedure in PLATON.
title: Fertilizer Trials on Dryland Winter Wheat
Creators: name: Sampson, I. G.
Publisher: name: Utah State University
Year: 1951

description: Wheat is one of the major crops of Utah and for more than 50 years farmers have been raising wheat on the dry lands of the state. The system they use is known as the alternate cropping or crop-follow system and consists of one year of crop alternating with one year of clean cultivation known as fallow.
Wheat removes a considerable amount of the natural plant food elements from the soil each year. This is especially true of nitrogen. According to Bracken and Greaves (9) the original low supply of nitrogen in most Utah soils together with the depleting effects of alternate wheat and fallow has the possibility of making nitrogen rather than moisture the limiting factor of crop production in certain dry-farm areas.
The amount of nitrogen removed from the soil by the wheat crop is only a portion of the total supply. Such factors as leaching to a lower depth beyond the feeding range of the plant, erosion, denitrification, and volatilization through biological and possibly chemical action are thought to be responsible for the loss of nitrogen unaccounted for by crop removal. The results of several investigators indicate that this loss is approximately twice as much as was removed by the crop.
Since nitrogen is one of the major factors responsible for high yields and high quality of wheat, it naturally follows that any reduction of the amount of nitrogen in the soil produces a corresponding reduction in yield and quality of wheat. Recent reports show that this condition exists in Utah as well as in other areas. As a result of this reduction in yield and quality of wheat, processors are concerned about the problems. The seriousness of the problem cannot be over-emphasized. Ways and means of checking these losses and subsequently increasing the yield and quality are being studied.
Three possible procedures for increasing soil nitrogen have been suggested: 1. the use of legumes, especially alfalfa, in a rotation program; 2. non-symbiotic nitrogen fixation: and 3. the use of commercial fertilizers.
Since legumes have not been grown to any great extent, the only other natural source of nitrogen has been non-symbiotic fixation. Evidence in this field of investigation, however, indicates that this source is inadequate and that other sources must be bad. Also, the data indicate that no effective methods have been found which increase non-symbiotic fixation. Limited information suggests that further study is needed on the use of legumes for increasing the nitrogen and organic matter content of dry farm soils. This investigation is confined to the use of commercial fertilizers as one solution to the general problem.

description: Despite its rapid growth and adaptability, Andropogon (Andropogon gayanus 12,465) was not preserved to address the severe feed deficit in the prolonged dry season in Ethiopia. Determining how the harvesting stage and additives (AD) affect the silage quality, animal preference, and digestibility of Andropogon was the objective of the current study. Three stages of harvesting (vegetative, boot, and full bloom) of the grass were used, and four AD (untreated (WO), with molasses (WM), with urea (WU), and with urea + molasses (WUM)) were factorially combined with a completely randomized design. With WO and molasses-based additives, the vegetative and boot-stage silage had a pleasant smell. The full-bloom silage scored lower than the other two stages for its odor, color, texture, and moldiness. The silage pH value with WM shows that it was lower in the vegetative (4.31) and boot (4.10) stages than in the full bloom (5.08) stages. At the boot stage, WM and WU showed higher silage crude protein (CP) content than WO silages. Based on dry matter (DM) intake, the Arab goat showed a higher preference for boot-stage silages with WM followed by WUM, while the lowest was with WO and WU. When compared to the other additives, goats fed WM and WU digested more DM, OM, and CP. The result also showed that the pH of the silage was strongly associated with texture. According to our findings, Andropogon, which was harvested at the boot stage and ensiled with WM has the potential to produce high-quality silage.

description: This is a more detailed version of our recent paper where we proposed, from first principles, a direct method for evaluating the exact fermion propagator in the presence of a general background field at finite temperature. This can, in turn, be used to determine the finite temperature effective action for the system. As applications, we discuss the complete one loop finite temperature effective actions for 0+1 dimensional QED as well as for the Schwinger model in detail. These effective actions, which are derived in the real time (closed time path) formalism, generate systematically all the Feynman amplitudes calculated in thermal perturbation theory and also show that the retarded (advanced) amplitudes vanish in these theories. Various other aspects of the problem are also discussed in detail.

description: Nonlinear pulse propagation inside highly nonlinear media requires accurate knowledge on the temporal response function of the materials used particular in the case of liquids. Here we study the impact of deuteration on the ultrafast dynamics of toluene and nitrobenzene via all optical Kerr gating, showing substantially different electronic and molecular contributions, which was quantified by fitting a multichannel decay model to the data points. Specifically we found that deuteration imposes the time-integrated nonlinearities to reduce particular for toluene which could be caused by both reduced electronic hyperpolarizabilities as well as weaker intermolecular interactions. The results achieved reveal that deuterated organic solvents represent promising materials for infrared photonics since they offer extended infrared transmission compared to their non-deuterated counterparts while maintained strong nonlinear responses.

description: In this paper we present new proofs of the non-embeddability of countably branching trees into Banach spaces satisfying property $(β_p)$ and of countably branching diamonds into Banach spaces which are $p$-AMUC for $p > 1$. These proofs are entirely metric in nature and are inspired by previous work of Jiří Matoušek. In addition, using this metric method, we succeed in extending these results to metric spaces satisfying certain curvature-like inequalities. Finally, we extend an embedding result of Tessera to give lower bounds on the compression for a class of Lipschitz embeddings of the countably branching trees into Banach spaces containing $\ell_p$-asymptotic models for $p \geq 1$.

title: Salt Effect on Water Requirements of Plants
Creators: name: Sallam, Abdel-Wahhab M. H.
Publisher: name: Utah State University
Year: 1963

description: Water requirement was defined by Briggs and Shantz in 1911 as the ratio of the weight of water absorbed by a plant during its growth to the weight of dry matter produced. Ballard (1933) and Williams (1935) defined water requirement as the ratio of the amount of water transpired to the amount of dry matter produced. Ballard (1933) and Williams (1935) defined water requirement as the ratio of the amount of water transpired to the amount of dry matter formed during the whole or any part of the life cycle of the plant. Miller (1938) and Kramer (1959) postulated that the water requirement is the ratio of water used to the dry matter produced, and therefore could more accurately be termed transpiration ratio because it is largely controlled by transpiration. Regardless of specific definition, the dry matter considered in such ratios is generally the amount harvested, including the entire plant except the roots. The amount of water measured is the amount lost during growth since the amount of water retained within the plant is insignificant when compared with either total water intake or the amount transpired. The water requirement thus constitutes a useful way to characterize the plant and soil-water conditions and plant growth.
The availability of soil water to a plant is one of the factors that vitally affects its water requirements. In turn, the availability of soil water is affected by soil moisture tension and the salt content of the soil. Thus it seems likely that a significant relationship may exist between a plant's water requirement and its degree of salt tolerance.
The relation between water requirement and salt tolerance could not be established based on the information found in the literature at this time. the study reported here was undertaken in an attempt to determine the effect of salt on the water requirement of plant species known to have different degrees of salt tolerance.

description: We report a unipolar, nonvolatile resistive switching in polycrystalline YMnO3 thin films grown by pulsed laser deposition and sandwiched between Au top and Ti/Pt bottom electrodes. The ratio of the resistance in the OFF and ON state is larger than 103. The observed phenomena can be attributed to the formation and rupture of conductive filaments within the multiferroic YMnO3 film. The generation of conductive paths under applied electric field is discussed in terms of the presence of grain boundaries and charged domain walls inherently formed in hexagonal YMnO3. Our findings suggest that engineering of the ferroelectric domains might be a promising route for designing and fabrication of novel resistive switching devices.

description: Cerium-doped manganite thin films were grown epitaxially by pulsed laser deposition at $720 ^\circ$C and oxygen pressure $p_{O_2}=1-25 $Pa and were subjected to different annealing steps. According to x-ray diffraction (XRD) data, the formation of CeO$_2$ as a secondary phase could be avoided for $p_{O_2}\ge 8 $Pa. However, transmission electron microscopy shows the presence of CeO$_2$ nanoclusters, even in those films which appear to be single phase in XRD. With O$_2$ annealing, the metal-to-insulator transition temperature increases, while the saturation magnetization decreases and stays well below the theoretical value for electron-doped La$_{0.7}$Ce$_{0.3}$MnO$_3$ with mixed Mn$^{3+}$/Mn$^{2+}$ valences. The same trend is observed with decreasing film thickness from 100 to 20 nm, indicating a higher oxygen content for thinner films. Hall measurements on a film which shows a metal-to-insulator transition clearly reveal holes as dominating charge carriers. Combining data from x-ray photoemission spectroscopy, for determination of the oxygen content, and x-ray absorption spectroscopy (XAS), for determination of the hole concentration and cation valences, we find that with increasing oxygen content the hole concentration increases and Mn valences are shifted from 2+ to 4+. The dominating Mn valences in the films are Mn$^{3+}$ and Mn$^{4+}$, and only a small amount of Mn$^{2+}$ ions can be observed by XAS. Mn$^{2+}$ and Ce$^{4+}$ XAS signals obtained in surface-sensitive total electron yield mode are strongly reduced in the bulk-sensitive fluorescence mode, which indicates hole-doping in the bulk for those films which do show a metal-to-insulator transition.

We use one-dimensional density-functional theory with a local-density approximation (LDA) on the same system and calculate densities and energies, which are compared with the `exact' ones. The `interacting-LDA system' corresponding to the LDA density is then found and its potential compared with the original one. Finally we calculate and compare the spatial entanglement of the electronic systems corresponding to the interacting-LDA and original interacting system.

description: Serving deep learning (DL) models on relational data has become a critical requirement across diverse commercial and scientific domains, sparking growing interest recently. In this visionary paper, we embark on a comprehensive exploration of representative architectures to address the requirement. We highlight three pivotal paradigms: The state-of-the-art DL-centric architecture offloads DL computations to dedicated DL frameworks. The potential UDF-centric architecture encapsulates one or more tensor computations into User Defined Functions (UDFs) within the relational database management system (RDBMS). The potential relation-centric architecture aims to represent a large-scale tensor computation through relational operators. While each of these architectures demonstrates promise in specific use scenarios, we identify urgent requirements for seamless integration of these architectures and the middle ground in-between these architectures. We delve into the gaps that impede the integration and explore innovative strategies to close them. We present a pathway to establish a novel RDBMS for enabling a broad class of data-intensive DL inference applications.

description: Purpose: Intra- and intercellular redox-signaling processes where found responsible in various physiological and pathological processes with cellular thiol groups as important signal transducers. Using cold atmospheric plasma (CAP), a similar oxidation pattern of thiol groups can be achieved. Hence, it must be clarified which role extracellular thiol groups play in mediating CAP effects and whether or not the effects of short-lived reactive species can be preserved in a molecule like cysteine. Methods: Physiological buffer solutions containing the amino acid cysteine were treated by an MHz argon plasma jet with molecular gas admixtures (kINPen) and transferred to cultured human keratinocytes. Cell proliferation, migratory activity, and metabolism were investigated. High-resolution mass spectrometry was used to estimate the impact of plasma generated species on thiol groups. Results: While treated physiologic cysteine concentrations showed no impact on cell behavior, artificially high concentrations decreased proliferation, migration and lactate secretion. GSH levels inside cells were stabilized. Conclusion: Extracellular thiol groups scavenge plasma-generated species and form a multitude of covalent modifications. Unexpectedly, human keratinocytes show only small functional consequences for treated physiologic cysteine concentrations. Results for high concentrated cysteine solutions indicate an improved cytostatic/cytotoxic impact by plasma treatment suggesting a potential application as a “preserving agent” of the chemical energy of plasma-derived species. © 2019 The Authors

description: Here, an artificial spin ice lattice is introduced that exhibits unique Ising and non-Ising behavior under specific field switching protocols because of the inclusion of coupled nanomagnets into the unit cell. In the Ising regime, a magnetic switching mechanism that generates a uni- or bimodal distribution of states dependent on the alignment of the field is demonstrated with respect to the lattice unit cell. In addition, a method for generating a plethora of randomly distributed energy states across the lattice, consisting of Ising and Landau states, is investigated through magnetic force microscopy and micromagnetic modeling. It is demonstrated that the dispersed energy distribution across the lattice is a result of the intrinsic design and can be finely tuned through control of the incident angle of a critical field. The present manuscript explores a complex frustrated environment beyond the 16-vertex Ising model for the development of novel logic-based technologies. © 2020 The Authors.

description: The loss of amorphous hydrogenated silicon nitride (a-SiN$_{x}$:H) is measured at 30 mK and 5 GHz using a superconducting LC resonator down to energies where a single-photon is stored, and analyzed with an independent two-level system (TLS) defect model. Each a-SiN$_{x}$:H film was deposited with different concentrations of hydrogen impurities. We find that quantum-regime dielectric loss tangent $\tanδ_{0}$ in a-SiN$_{x}$:H is strongly correlated with N-H impurities, including NH$_{2}$. By slightly reducing $x$ we are able to reduce $\tanδ_0$ by approximately a factor of 50, where the best films show $\tanδ_0$ $\simeq$ 3 $\times$ 10$^{-5}$.

description: The orbital symmetries of electron doped iron-arsenide superconductors Ba(Fe1-xCox)2As2 have been measured with x-ray absorption spectroscopy. The data reveal signatures of Fe d electron itinerancy, weak electronic correlations, and a high degree of Fe-As hybridization related to the bonding topology of the Fe dxz+yz states, which are found to contribute substantially at the Fermi level. The energies and detailed orbital character of Fe and As derived unoccupied s and d states are found to be in remarkably good agreement with the predictions of standard density functional theory.

description: We report interesting observations in 1.2 MeV Ar8+ ion irradiated ZnO which, to the best of our knowledge, have not been published earlier and will be useful for the scientific community engaged in research on ZnO. Irradiation with the initial fluence 1 X 10^15 ions/cm^2 changes the colour of the sample from white to orange while the highest irradiation fluence makes it dark reddish brown that appears as black. Such changes in colour can be correlated with the oxygen vacancy type defects. No significant change in the grain size of the irradiated samples, as revealed from the x-ray diffraction (XRD) line width broadening, has been observed. Increase of surface roughness due to sputtering is clearly visible in scanning electron micrographs (SEM) with highest fluence of irradiation. Room temperature Photoluminescence (PL) spectrum of the unirradiated sample shows intense ultra-violet (UV) emission (~ 3.27 eV) and less prominent defect level emissions (2-3 eV). The overall emission is largely quenched due to initial irradiation fluence. But with increasing fluence UV emission is enhanced along with prominent defect level emissions. Remarkably, the resistivity of the irradiated sample with highest fluence is reduced by four orders of magnitude compared to that of the unirradiated sample. This indicates increase of donor concentration as well as their mobility due to irradiation. Oxygen vacancies are deep donors in ZnO, but surely they influence the stability of the shallow donors (presumably zinc interstitial related) and vice versa. This is in conformity with recent theoretical calculations.

Recreational travel as a function of urbanization and accessibility
Creators: name: Wyne, Harold Murray
Publisher: name: University of British Columbia

description: The hypothesis for this study is that recreational automobile tourist patterns are urban-oriented and are a function of accessibility. British Columbia was chosen as a case study area in which this hypothesis could be tested. British Columbia was examined in terms of its accessibility by automobile from the rest of North America. Its internal characteristics were considered in relationship to its primary highway system. Tourist travel was analyzed in terms of American travel, regional points-of-origin of American and Canadian travellers, points-of-entry to British Columbia and regional distribution of traffic, regional distribution of tourist accommodation facilities and average traffic patterns. Published and unpublished studies conducted by the Federal and Provincial Governments were reviewed and pertinent data was extrapolated. The points-of-origin of most non-resident automobile tourists are the urbanized portions of the Pacific Coast of the United States and the province of Alberta. It is felt that these factors shall probably continue in the future, but that the demand for automobile recreational travel will continue to grow. Most automobile tourists visit British Columbia during the months of July and August. A relationship exists between ports-of-entry and time spent in the province which might, or might not, have a bearing on the propensity of tourists to travel deep into the province. It is felt that more convenient access to the Trans-Canada Highway, and to more northern points in the province from the southern interior, would increase the tendency of visitors to these areas, to travel north-wards. It was found that an increase in tourists entering the province at Prince Rupert occured in 1966. It is felt that this increase is largely attributable to improved access - the introduction of the Prince Rupert-Kelsey Bay ferry system in 1966, integrated with the already existing system joining the continental United States to Alaska. The loop tours made possible by recent improvements in the northern road system were found to coincide with a marked increase in travel to those regions. Recreational travel patterns in British Columbia were found to be urban-oriented and a function of accessibility, which agreed with the hypothesis of this paper and verified it. In view of this it is suggested that the Province of British Columbia might undertake the construction of a rationally conceived loop system of highways to serve tourism. It is felt that the role of accessibility, road geometries and split modes of travel (automobile and ferry) is worthy of more intense research.

description: The cytotoxicity of two different types of Multi-walled Carbon Nanotubes (MWCNTs)in A549 lung epithelial cells and HepG2 hepatocytes was investigated. One MWCNT still contained iron that was used as a catalyst during production, while the other one had all iron removed in a post-production heat treatment resulting in significantly fewer surface defects. The WST-8 assay was applied to test cell viability. To check the integrity of the cell membrane, we performed the lactate dehydrogenases assay (LDH)and measured the cellular production of reactive oxygen species (ROS). Finally, to examine cell proliferation, we conducted a cell cycle analysis. The results showed a dose- and time-dependent decrease in cell viability for both MWCNTs in both cell types. Moreover, a dose- and time-dependent increase in LDH leakage was detected, thereby indicating a decreased membrane integrity. The production of ROS was significantly increased in the case of the heat-treated MWCNTs. The heat-treated MWCNTs showed significantly stronger adverse effects when compared to the non-treated MWCNTs. Additionally, the heat-treated MWCNTs induced a dose-dependent cell cycle arrest in A549 cells. Both MWCNTs induced a significant cytotoxicity, whereby the heat treatment, leading to a decrease in surface defects, further increased the indicated adverse effects. © 2019 The Authors

description: The drag-free satellites of LISA will maintain the test masses in geodesic motion over many years with residual accelerations at unprecedented small levels and time delay interferometry (TDI) will keep track of their differential positions at level of picometers. This may allow investigations of fine details of the gravitational field in the Solar System previously inaccessible. In this spirit, we present the concept of a method to measure directly the gravitational effect of the density of diffuse Local Dark Matter (LDM) with a constellation of a few drag-free satellites, by exploiting how peculiarly it would affect their relative motion. Using as test bed an idealized LISA with rigid arms, we find that the separation in time between the test masses is uniquely perturbed by the LDM, so that they acquire a differential breathing mode. Such a LDM signal is related to the LDM density within the orbits and has characteristic spectral components, with amplitudes increasing in time, at various frequencies of the dynamics of the constellation. This is the relevant result, in that the LDM signal is brought to non-zero frequencies.

Estimations of educational production functions and technical efficiency of public primary schools in Tasmania

description: The study here examines the performance of Tasmanian public primary schools over the period of 2000 to 2007. The three principal objectives of the study are (i) to investigate the effects of school resources on students' academic achievement; (ii) evaluate schools' technical efficiency; and (iii) to identify the factors that affect the schools' technical efficiency. To explore the first objective, an educational production function is estimated. The second and the third objectives are examined by employing two techniques, namely, Stochastic Production Frontier (SPF) and Data Envelopment Analysis (DEA). On the basis of the estimation of a Fixed Effects model of a Tasmanian educational production function, a one per cent increase in educational expenditure per student is associated with an increase in the reading, writing and numeracy scores of 0.38%, 0.36% and 0.43%, ceteris paribus. Male students' performance was on average lower than female students. Evidence of relatively lower performance by indigenous students was found. Students' performance was also negatively affected by their level of absenteeism. Positive effects of parental education on Tasmanian students' academic achievement were found but the effects of parental occupation were not statistically significant. The SPF estimates suggest that Tasmanian public primary schools are almost technically efficient with the average technical efficiency score constant at 97% from 2003 to 2007. No technical efficiency change in the public primary educational sector in Tasmania over the period could be detected. The schools' technical inefficiency scores iii were positively associated with students' suspension rates. Mothers' occupational status had a significant negative effect on technical inefficiency. The average technical efficiency obtained under the DEA (assuming variable returns to scale) was constant at 95% over the study period (implying no technical efficiency change). On the basis of Tobit regression results, positive effects of parental occupation on technical efficiency were also found. The number of Aboriginal and Torres Strait Islander students; students who had English as a second language; the number of disability students; students' absenteeism rate and that a school was classified as rural all had a negative effect on technical efficiency. Urban schools were found to be more scale efficient than rural schools. Lower scale efficiency for rural schools was due to non-optimal school size (due to remote location and low population density). The efficiency rankings of schools based on the SPF and DEA methods vary due to (i) the different ways the SPF and DEA discriminate between schools in the construction of the production frontiers, and (ii) the different methodologies SPF and DEA apply to control for environmental factors.

description: We present a divergence-free and $H(div)$-conforming hybridized discontinuous Galerkin (HDG) method and a computationally efficient variant called embedded-HDG (E-HDG) for solving stationary incompressible viso-resistive magnetohydrodynamic (MHD) equations. The proposed E-HDG approach uses continuous facet unknowns for the vector-valued solutions (velocity and magnetic fields) while it uses discontinuous facet unknowns for the scalar variable (pressure and magnetic pressure). This choice of function spaces makes E-HDG computationally far more advantageous, due to the much smaller number of degrees of freedom, compared to the HDG counterpart. The benefit is even more significant for three-dimensional/high-order/fine mesh scenarios. On simplicial meshes, the proposed methods with a specific choice of approximation spaces are well-posed for linear(ized) MHD equations. For nonlinear MHD problems, we present a simple approach exploiting the proposed linear discretizations by using a Picard iteration. The beauty of this approach is that the divergence-free and $H(div)$-conforming properties of the velocity and magnetic fields are automatically carried over for nonlinear MHD equations. We study the accuracy and convergence of our E-HDG method for both linear and nonlinear MHD cases through various numerical experiments, including two- and three-dimensional problems with smooth and singular solutions. The numerical examples show that the proposed methods are pressure robust, and the divergence of the resulting velocity and magnetic fields is machine zero for both smooth and singular problems.

description: Despite increasing knowledge gained based on multidisciplinary research, plasma medicine still raises various questions regarding specific effects as well as potential risks. With regard to significant statements about in vivo applicability that cannot be prognosticated exclusively based on in vitro data, there is still a deficit of clinical data. This study included a clinical follow-up of five probands who had participated five years previously in a study on the influence of cold atmospheric pressure plasma (CAP) on the wound healing of CO2 laser-induced skin lesions. The follow-up included a complex imaging diagnostic involving dermatoscopy, confocal laser scanning microscopy (CLSM) and hyperspectral imaging (HSI). Hyperspectral analysis showed no relevant microcirculatory differences between plasma-treated and non-plasma-treated areas. In summary of all the findings, no malignant changes, inflammatory reactions or pathological changes in cell architecture could be detected in the plasma-treated areas. These unique in vivo long-term data contribute to a further increase in knowledge about important safety aspects in regenerative plasma medicine. However, to confirm these findings and secure indication-specific dose recommendations, further clinical studies are required. © 2020 by the authors.
