I survived. Thanks to my daughter: a study of elderly women's experience in hospital
Creators: name: Freeman, Amy
Publisher: name: University of British Columbia
Year: 2009

description: This research examined how the needs of elderly women are being met in the hospital setting. Qualitative data were gathered through in-depth interviews with eleven women between the ages of 70 and 93 who had had a hospital stay in the previous year. Data analysis revealed that the system failed to attend to participants' age specific needs. This failure created gaps in care which were particularly troubling for elderly female patients whose frailty made them susceptible to additional health problems. Participants received inadequate care in such areas as bathing, walking assistance and help with eating. Hearing impairments and denture issues were at times overlooked. These gaps in care caused participants to view a hospital stay as a matter of survival. Participants developed strategies to cope with gaps in care which included lowering their expectations, developing support networks and relying on family members to meet their basic needs and advocate on their behalf. Recommendations for change include identifying elderly women as a vulnerable patient population and defining the problems they face as structural issues as opposed to individual problems.

description: Motivated by the very recent discovery of fully open-flavor exotic states $X_0(2900)$ and $X_1(2900)$ by the LHCb Collaboration, we study possible interpretations of these exotic states by QCD Sum Rules method. We have calculated mass and decay constant by traditional QCD Sum Rules analysis and Monte-Carlo based analysis. $X_0(2900)$ and $X_1(2900)$ are studied in molecular and diquark-antidiquark tetraquark pictures, respectively. Obtained mass results agree well with the masses observed in the experiment. We also made a Monte-Carlo based analysis within QCD Sum Rules for the mass and decay constant distributions to investigate the possible assignments for the structures of $X_0(2900)$ and $X_1(2900)$.

description: Mandatory livestock price reporting was implemented in April 2001. Empirical evidence indicates a significant change in volatility occurred in publicly reported fed cattle grid premiums and discounts after its policy reform was implementationed. Empirical analysis of grid premiums and discounts across the pre- and post -reform periods indicates that increased transparency is compatible with either an increase or a decrease in price volatility in the post- MPR period. Furthermore, it appears that the public price reporting system for weekly grid premiums and discounts failed to provide an adequate level of transparency prior to the implementation of price reporting policy reforms. Our methodology extends the literature on the use of volatility measures for investigating issues associated with market transparency. This extension can be applied to the development of volatility measures for monitoring the price reporting behavior of firms.

description: A p-local finite group consists of a finite p-group S, together with a pair of categories which encode ``conjugacy'' relations among subgroups of S, and which are modelled on the fusion in a Sylow p-subgroup of a finite group. It contains enough information to define a classifying space which has many of the same properties as p-completed classifying spaces of finite groups. In this paper, we study and classify extensions of p-local finite groups, and also compute the fundamental group of the classifying space of a p-local finite group.

description: Radical wool marketing changes are mooted by the Australian Wool Corporation. While these intentions include wide ranging increases in market power for this supreme marketing authority, the overall proposals in their entirety, are argued as necessary to operationalize newly available wool selling and handling innovations. Supporting empirical evidence on the gains from adopting these innovations relies on spatial equilibrium models not fully in accord with the economic theory on which they are based. This paper sets out the shortcomings of these back-up studies. Based on a reconsideration of the theoretical premises, counter policy measures are advanced for consideration.

description: In the Randall-Sundrum scenario, we analyse the dynamics of an AdS5 braneworld when conformal matter fields propagate in five dimensions. We show that conformal fields of weight -4 are associated with stable geometries which describe the dynamics of inhomogeneous dust, generalized dark radiation and homogeneous polytropic dark energy on a spherically symmetric 3-brane embedded in the compact AdS5 orbifold. We discuss aspects of the radion stability conditions and of the localization of gravity in the vicinity of the brane.

description: We investigate the 5d transition metal oxide BaOsO$_3$ within a combination of density functional theory (DFT) and dynamical mean-field theory (DMFT), using a matrix-product-state impurity solver. BaOsO$_3$ has 4 electrons in the t$_{2g}$ shell akin to ruthenates but stronger spin-orbit coupling (SOC) and is thus expected to reveal an interplay of Hund's metal behavior with SOC. We explore the paramagnetic phase diagram as a function of SOC and Hubbard interaction strengths, identifying metallic, band (van-Vleck) insulating and Mott insulating regions. At the physical values of the two couplings we find that BaOsO$_3$ is still situated inside the metallic region and has a moderate quasiparticle renormalization $m^*/m \approx 2$; consistent with specific heat measurements. SOC plays an important role in suppressing electronic correlations (found in the vanishing SOC case) through the splitting of a van-Hove singularity (vHs) close to the Fermi energy, but is insufficient to push the material into an insulating van-Vleck regime. In spite of the strong effect of SOC, BaOsO$_3$ can be best pictured as a moderately correlated Hund's metal.

Risk and Uncertainty

description: Risk is often perceived by farmers as being more formidable in new technologies emanating from agricultural research than in more traditional practices. Consequently risk may tend to act as an impediment to adoption of improved practices as well as a general friction on efficient use of resources. Research and extension workers in agriculture may thus wish to identify technologies that are not only "improved" (more productive and profitable on the average) but are also less risky in that they would be preferred by "risk-averse" farmers. The extent to which this identification can proceed in the absence of knowledge of farmers' individual attitudes to risk is explored here through application of the concepts of stochastic dominance.

description: Morphology is integral to body temperature regulation. Recent advances in understanding of thermal physiology suggest a role of the avian bill in thermoregulation. To explore the adaptive significance of bill size for thermoregulation we characterized relationships between bill size and climate extremes. Most previous studies focussed on climate means, ignoring frequencies of extremes, and do not reflect thermoregulatory costs experienced over shorter time scales. Using 79 species (9847 museum specimens), we explore how bill size variation is associated with temperature extremes in a large and diverse radiation of Australasian birds, Meliphagides, testing a series of predictions. Overall, across the continent, bill size variation was associated with both climate extremes and means and was most strongly associated with winter temperatures; associations at the level of climate zones differed from continent-wide associations and were complex, yet consistent with physiology and a thermoregulatory role for avian bills. Responses to high summer temperatures were nonlinear suggesting they may be difficult to detect in large scale continental analyses using previous methodologies. We provide strong evidence that climate extremes have contributed to the evolution of bill morphology in relation to thermoregulation and show the importance of including extremes to understand fine scale trait variation across space.
Higher Derivative Operators as Counterterms in Orbifold Compactifications

description: In the context of 5D N=1 supersymmetric models compactified on S_1/Z_2 or S_1/(Z_2 x Z_2') orbifolds and with brane-localised superpotential, higher derivative operators are generated radiatively as one-loop counterterms to the mass of the (brane or zero mode of the bulk) scalar field. It is shown that the presence of such operators which are brane-localised is not related to the mechanism of supersymmetry breaking considered (F-term, discrete or continuous Scherk-Schwarz breaking) and initial supersymmetry does not protect against the dynamical generation of such operators. Since in many realistic models the scalar field is commonly regarded as the Higgs field, and the higher derivative operators seem a generic presence in orbifold compactifications, we stress the importance of these operators for solving the hierarchy problem.

The analysis was done for spring wheat using the BRP-RCCP calculator, as developed by the National Corn Growers Association. Three representative counties (Hettinger, Ward and Cavalier) were chosen in North Dakota. Historic and projected data were used to analyze 2002 to 2010 crop years. A comparison of the BRP-RCCP programs to the current farm program was done. From 2002 to 2005, Ward County would have received nearly identical payments under the BRP-RCCP program and the current farm program. The Hettinger County farm would have received considerably more under the BRP-RCCP program - $76.87 per acre, compared with $38.99 under the existing farm program. This amounts to $9.22 per acre per year. For the Cavalier County farm, the advantage to the BRP-RCCP program was only $7.56 per acre for the four-year period.

description: Complications in preparing and preserving quantum correlations stimulate recycling of a single quantum resource in information processing and communication tasks multiple times. Here, we consider a scenario involving multiple independent pairs of observers acting with unbiased inputs on a single pair of spatially separated qubits sequentially. In this scenario, we address whether more than one pair of observers can demonstrate quantum advantage in some specific $2 \rightarrow 1$ and $3 \rightarrow 1$ random access codes. Interestingly, we not only address these in the affirmative, but also illustrate that unbounded pairs can exhibit quantum advantage. Furthermore, these results remain valid even when all observers perform suitable projective measurements and an appropriate separable state is initially shared.

description: The Bekenstein-Milgrom gravity theory with a modified Poisson equation is tested here for the existence of triaxial equilibrium solutions. Using the non-negative least square method, we show that self-consistent triaxial galaxies exist for baryonic models with a mild density cusp $ρ\sim {Σ\over r}$. Self-consistency is achieved for a wide range of central concentrations, $Σ\sim 10-1000\mathrm{M_{\odot}pc^{-2}}$, representing low-to-high surface brightness galaxies. Our results demonstrate for the first time that the orbit superposition technique is fruitful for constructing galaxy models beyond Newtonian gravity, and triaxial cuspy galaxies might exist without the help of Cold dark Matter.

description: The paper surveys articles examining the economic impacts of a livestock disease outbreak and focuses on modeling issues. One set of papers considers setting an import barrier when there is a livestock disease risk. They show that the level of a risk-based import barrier is sensitive to the impact of disease on economic welfare. The remaining articles focus on estimates of the economic impacts. An outbreak is modeled in a U.S. agricultural sector model and shows the importance of lost exports and consumer response to the magnitude of losses. The final paper argues for de-composition of the welfare impacts. Lessons for future research include improved links to epidemiological research, improved inclusion of trade, extension to non-agricultural sectors, and knowledge of consumer response.
Radiative Flow in a Luminous Disk

subject: FOS: Physical sciences

description: Radiatively-driven flow in a luminous disk is examined in the subrelativistic regime of $(v/c)^1$, taking account of radiation transfer. The flow is assumed to be vertical, and the gravity and gas pressure are ignored. When internal heating is dropped, for a given optical depth and radiation pressure at the flow base (disk ``inside''), where the flow speed is zero, the flow is analytically solved under the appropriate boundary condition at the flow top (disk ``surface''), where the optical depth is zero. The loaded mass and terminal speed of the flow are both determined by the initial conditions; the mass-loss rate increases as the initial radiation pressure increases, while the flow terminal speed increases as the initial radiation pressure and the loaded mass decrease. In particular, when heating is ignored, the radiative flux $F$ is constant, and the radiation pressure $P_0$ at the flow base with optical depth $τ_0$ is bound in the range of $2/3 < cP_0/F < 2/3 + τ_0$. In this case, in the limit of $cP_0/F = 2/3 + τ_0$, the loaded mass diverges and the flow terminal speed becomes zero, while, in the limit of $cP_0/F = 2/3$, the loaded mass becomes zero and the terminal speed approaches $(3/8)c$, which is the terminal speed above the luminous flat disk under an approximation of the order of $(v/c)^1$. We also examine the case where heating exists, and find that the flow properties are qualitatively similar to the case without heating.

description: This paper examines the economics of farm decisions to prevent and control infectious livestock disease. In the case of diseases with costly control tolerating some level of disease is often rational to the producer. Public policy intervention is based on future value and public good aspects of disease control which can lead to a discrepancy between private and public action thresholds. Producer incentives for disease management can be changed through new technologies that lower the cost of prevention or control, subsidies or cost sharing of control measures, or on the consumer side, a change in public desire for disease risk-free products that changes relative prices. Economists can incorporate appropriate epidemiology of a given disease in economic models to inform policy-makers on optimal value or method of subsidies that would prove most effective to make private incentives compatible with public policy goals.
Clinical teacher perceptions of power in the student/teacher relationship within the transformative curriculum
Creators: name: Groening, Marlee Rose
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this grounded theory study was to explore the perceptions of clinical teachers concerning power in the clinical teacher/student relationship within the Transformative Curriculum. The findings of this study reflect the perceptions of 10 clinical teachers who teach within several identified Transformative Nursing Curriculum within the Lower Mainland of British Columbia. The teachers were contacted using two sampling methods, the snowball method and theoretical sampling. The findings of this study indicate that these clinical teachers were generally quite committed to the transformative philosophy and minimizing power differentials between students and clinical teachers. Their philosophies were often revealed through the language and metaphors they used when discussing their perceptions about teacher and student roles and their perspectives on power. The seasoned clinical teacher beliefs and philosophies appeared to be well established prior to their employment with a Transformative nursing curriculum. In contrast, the new clinical teacher philosophies seemed to be a bit more malleable and were influenced by the curriculum. Most teachers used a variety of approaches to equalize power in the clinical settings. This was apparent in their approaches to learning experiences in the clinical setting, such as student involvement in patient assignments, engaging students in the learning process, and negotiation. Teachers also attempted to equalize power by developing relationships with students. Some approaches teachers used were to 'get to know the student', focusing on the positive, respecting the student and demonstrating teacher vulnerability and humanness. At times, the teachers experienced notable tensions between the curriculum philosophy of egalitarian relationships, and the professional mandate of the clinical teacher role. These tensions typically occurred when the realities of clinical teaching conflicted with the transformative ideals, such as when acknowledging patient safety, working with the struggling student, and in the promotion of and accounting for student learning. Tensions were also evident between the complex clinical context and clinical teacher pursuits toward egalitarian relationships with students. Examples of these included short clinical rotations, school or agency policies around incident reports as well as differing teacher philosophies. Compounding these tensions, were high teacher workload, high patient acuity, weak students and teacher fatigue. These factors consumed teacher energy, which was identified as necessary in pursuing equal relationships with students.

description: Light rings (LRs) play an important role in gravitational wave observations and black hole photographs. In this paper, we investigate general features of LRs in stationary, axisymmetric, asymptotically flat spacetimes with or without horizons. For a nonextremal black hole, we show explicitly that there always exist at least two LRs propagating in opposite directions, where the outermost one is radially unstable. For an extremal black hole, we show that there exists at least one retrograde LR. We find that there is at least one LR which is angularly stable. The stability analysis does not involve any energy condition. Our method also applies to horizonless spacetimes and we prove that LRs always appear in pairs. Only some natural and generic assumptions are used in our proof. The results are applicable to general relativity as well as most modified theories of gravity. In contrast to previous works on this issue, we obtain much stronger results with a much more straightforward approach.

description: Vortex dynamics in a bilayer thin film superconductor are studied through a Josephson-coupled double layer XY model. A renormalization group analysis shows that there are three possible states associated with the relative phase of the layers: a free vortex phase, a logarithmically confined vortex-antivortex pair phase, and a linearly confined phase. The phases may be distinguished by measuring the resistance to counterflow current. For a geometry in which current is injected and removed from the two layers at the same edge by an ideal (dissipationless) lead, we argue that the three phases yield distinct behaviors: metallic conductivity in the free vortex phase, a power law I-V in the logarithmically confined phase, and true dissipationless superconductivity in the linearly confined phase. Numerical simulations of a resistively shunted Josephson junction model reveal size dependences for the resistance of this system that support these expectations.

I argue that the coexistence of the large Nernst signal and the insulating-like in-plane resistivity in underdoped cuprates rules out the vortex scenario, but agrees remarkably well with our theory.

description: The temperature dependence of the magnetic specific heat has been studied experimentally and theoretically in the semimagnetic semiconductor Pb_{1-x}Eu_{x}Te for x=0.027 and x=0.073, over the temperature range from 0.5 K to 10 K, in magnetic fields up to 2 T. There was a maximum in the magnetic specific heat between 1 and 3 K even in zero and low magnetic fields; this maximum shifted toward higher temperatures with increasing magnetic field. The experimental data have been analyzed in the framework of a model in which we assume that the ground states of europium ions are split even without an external magnetic field. We present arguments which support this assumption and we show that it is possible to find a physical mechanism leading to the splitting which can explain the experimental results.

description: A simplified method to compute $R_t$, the Effective Reproduction Number, is presented. The method relates the value of $R_t$ to the estimation of the doubling time performed with a local exponential fit. The condition $R_t = 1$ corresponds to a growth rate equal to zero or equivalently an infinite doubling time. Different assumptions on the probability distribution of the generation time are considered. A simple analytical solution is presented in case the generation time follows a gamma distribution.

description: There has been a rapid increase in recent years in invasive species and animal management economic research. Expanded interest in the topic has been partially driven by the practical importance of public policy to deal effectively with invasive species, given its public good aspects. This paper shows that the basic criteria of public goods: non-rivalry and non-excludability, apply directly to animal disease border measures and eradication services, with some caveats. It is also argued that public policy should assess disease control and eradication on grounds of biology, national economic interests, and international cooperation. Specific regulations and programs must be evaluated on the basis of cost benefit principles.

The diode turn-on voltage is shown to be highly sensitive to the arylamine/metal charge-transfer interfaces and thus can serve as a probe in detecting such organic/metal interfaces. We show that the diode electrical performance could be tuned through engineering the arylamine/metal interfaces via controlling the factors of anode work function, arylamine substitute groups, and active layer surface morphology etc. The conduction mechanism of the diodes is shown to be injection limited, which could be well described with Richardson-Schottky thermonic emission model. Our work may provide some insight into the use of single-layer organic diode and interfacial engineering method to rapidly probe the organic/metal and even organic/organic charge-transfer interfaces.

description: Utilizing an original data set, we use regression analysis to estimate the impact of various factors on the earnings and the gender wage gap of the agribusiness graduates. Findings indicate that factors such as education, experience, gender, job sector, status and specialty, etc., are important factors in determining earnings. In particular, characteristics such as experience through a foreign internship during college, marketing, accounting and finance specialties are associated with a relatively high market value. Despite progress in recent years, results suggest that a 19 % wage gap still exists between men and women due to differences in human capital characteristics, differences in labor force participation behavior and individual lifestyle choices.

description: We compute the nonplanar contribution to the universal anomalous dimension of the SU(4)-singlet twist-two operators in N=4 supersymmetric Yang-Mills theory at four loops through Lorentz spin 18. From this, we numerically evaluate the nonplanar contribution to the four-loop lightlike cusp anomalous dimension and derive the transcendental $ζ_3$ and $ζ_5$ parts of the universal anomalous dimension for arbitrary Lorentz spin in analytic form. As for the lightlike cusp anomalous dimension and the $ζ_5$ part of the universal anomalous dimension, we confirm previous results.

description: It is widely acknowledged that competition is no longer between individual firms, but between supply chains. A number of studies have indicated that supply chain integration and quality management have become essential to obtain competitive advantage. The present study tests the relationships among supply chain integration, quality management practices and firm performance in 229 Chinese pork slaughterhouses and processors using structural equation modeling. The most important results are that quality management is positively linked with firm performance. As managers put it "Quality is the life of the enterprise". Pork processing managers that wish to improve their performance are therefore advised to invest in quality management. Equally interesting is the indirect link of supply chain integration through quality management with firm performance. To improve quality of their products and reduce uncertainty in hog supply chains, companies are advised to develop more integrated relationships with their suppliers. However, in contrast to earlier studies, the direct link of supply chain integration and firm performance was not significant. This result may indicate that the Chinese pork processing industry is still in an early stage of SC integration.
Radiative Flow in a Luminous Disk II

description: Radiatively-driven transfer flow perpendicular to a luminous disk is examined in the subrelativistic regime of $(v/c)^1$, taking into account the gravity of the central object. The flow is assumed to be vertical, and the gas pressure is ignored, while internal heating is assumed to be proportional to the gas density. The basic equations were numerically solved as a function of the optical depth, and the flow velocity, the height, the radiative flux, and the radiation pressure were obtained for a given radius, an initial optical depth, and initial conditions at the flow base (disk ``inside''), whereas the mass-loss rate was determined as an eigenvalue of the boundary condition at the flow top (disk ``surface''). For sufficiently luminous cases, the flow resembles the case without gravity. For less-luminous cases, however, the flow velocity decreases, and the flow would be impossible due to the existence of gravity in the case that the radiative flux is sufficiently small. Application to a supercritical accretion disk with mass loss is briefly discussed.

Two dimensional Ising model with long-range competing interactions

description: The two-dimensional Ising model with competing short range ferromagnetic interactions and long range antiferromagnetic interactions is perhaps the most simple one containing the minimal microscopic ingredients necessary for an appropriate description of the macroscopic properties of ultrathin films and quasi--two--dimensional magnetic materials. Despite such relative simplicity, the frustration introduced by the competition between interactions generates complex behaviors that have eluded, up to now, a complete understanding of its general properties. In this work we review recent advances in the understanding of both equilibrium and non-equilibrium properties of the model. This includes a detailed description of several known properties of the thermodynamical phase diagram, as well as the existence of several types of metastable states and their influence in the low temperature dynamics.

Can competition between crystal field and Kondo effect cause non-Fermi liquid like behavior?

description: The recently reported unusual behavior of the static and dynamical magnetic susceptibility as well as the specific heat in Ce$_{1-x}$La$_{x}$Ni$_{9}$Ge$_4$ has raised the question of a possible non-Fermi liquid ground state in this material. We argue that for a consistent physical picture the crystal field splitting of two low lying magnetic doublets of the Ce $4f$-shell must be taken into account. Furthermore, we show that for a splitting of the order of the low temperature scale $T^*$ of the system a crossover behavior between an SU(4) and an SU(2) Kondo effect is found. The screening of the two doublets occurs on different temperature scales leading to a different behavior of the magnetic susceptibility and the specific heat at low temperatures. The experimentally accessible temperature regime down to 50mK still lies in the extended crossover regime into a strong coupling Fermi-liquid fixed point.

description: We present a code to compute the relic density of dark matter in the Next-to-Minimal Supersymmetric Standard Model (NMSSM). Dominant corrections to the Higgs masses are calculated with NMHDECAY as well as theoretical and collider constraints. All neutralino annihilation and coannihilation processes are then computed with an extended version of micrOMEGAs, taking into acount higher order corrections to Higgs vertices. We explore the parameter space of the NMSSM and consider in particular the case of a bino LSP, of a mixed bino-higgsino LSP and of a singlino LSP. As compared to the MSSM, neutralino annihilation is often more efficient as it can take place via (additional) Higgs resonances as well as annihilation into light Higgs states. Models with a large singlino component can be compatible with WMAP constraints.

description: (Abridged) Classification schemes for YSOs are based on evaluating the degree of dissipation of the surrounding envelope, whose main effects are the extinction of the optical radiation from the central YSO and re-emission in the far-infrared. Since extinction is a property of column density along the line of sight, the presence of a protoplanetary disk may lead to a misclassification when the system is viewed edge-on. We performed radiative transfer calculations, using the axysimmetric 3D radiative transfer codes RADMC and RADICAL, to show the effects of different geometries on the main indicators of YSO evolutionary stage, like the slope of the flux between 2 and 24mum, the bolometric temperature and the optical depth of silicates and ices. We show that for systems viewed at intermediate angles the 'classical' indicators of evolution accurately trace the envelope column density, and they all agree with each other. On the other hand, edge-on system are misclassified for inclinations larger than ~65deg. In particular, silicate emission, typical of pre-main sequence stars with disks, turns into absorption when the disk column density reaches 1e22cm-2, corresponding e.g. to a 5e-3 Msun flaring disk viewed at 64deg. A similar effect is noticed in all the other classification indicators studied alpha, Tbol, and the H2O and CO2 ices absorption strengths. This misclassification has a big impact on the nature of the flat-spectrum sources (alpha ~0), whose number can be explained by simple geometrical arguments without invoking evolution. A reliable classification scheme using a minimal number of observations is constituted by observations of the mm-flux with both a single dish and an interferometer.

description: The overwhelming challenge of depleting fossil fuels and anthropogenic carbon emissions has driven research into alternative clean sources of energy. To achieve the goal of a carbon neutral economy, the harvesting of sunlight by using photocatalysts to split water into hydrogen and oxygen is an expedient approach to fulfill the energy demand in a sustainable way along with reducing the emission of greenhouse gases. Even though the past few decades have witnessed intensive research into inorganic semiconductor photocatalysts, their quantum efficiencies for hydrogen production from visible photons remain too low for the large scale deployment of this technology.
