description: The entrenched separation of primary care and public health in the United States has been damaging and self-perpetuating. As both sectors struggle to meet their own challenges, population health has deteriorated due to their failure to integrate. For the first time, The Practical Playbook offers professionals in primary care and public health a roadmap to integrating their work with the larger goals of population health. Drawing on the experiences of hundreds of public health and primary care professionals from across the US, this book explains: · Why is population health important? · What are the practical steps that clinicians and public health professionals can take to work together to meet the needs of their community? · What are the signs that you're on the right track, and how can progress be sustained? Comprising case studies, practical recommendations, data resources, and commentaries from national leaders on both sides, The Practical Playbook is the new benchmark for primary care and public health practitioners working to improve population health

description: As a first step towards a theory of differential equations involving para-Grassmann variables the linear equations with constant coefficients are discussed and solutions for equations of low order are given explicitly. A connection to n-generalized Fibonacci numbers is established. Several other classes of differential equations (systems of first order, equations with variable coefficients, nonlinear equations) are also considered and the analogies or differences to the usual (''bosonic'') differential equations discussed.

description: A state coupling between the hydrostatic (volumetric) and deviatoric parts of the free energy is introduced in a damage mechanics model relevant for the quasi-brittle materials. It is shown that it describes the large dilatancy of concrete under compression and the different localization angles and damage levels in tension and compression. A simple isotropic description is used, although similar ideas can be extended to anisotropic damage. The model is identified with respect to tensile and compression tests and validated on bi-compression and bi-tension. Fully written in three dimensions under the framework of thermodynamics of irreversible processes, it allows further developments within a finite element code.

description: In two dimensions a vortex lattice can melt by quantum fluctuations into a non-superfluid Quantum Vortex Liquid (QVL). To determine the melting conditions, we compute the bare vortex hopping rate by exact diagonalization of square clusters near half filling. Mapping our effective Hamiltonian to the Boson Coloumb Liquid simulated in Phys. Rev. Lett. 73, 826 (1994), we expect a QVL above a melting density of 0.0065 vortices per lattice site. We also compute the Hall conductivity using adiabatic curvatures. As a function of boson filling it reverses sign at half filling in a sharp transition accompanied by a vanishing temperature scale. At half filling, each vortex carries a spin half quantum number (`v-spin'), as a consequence of local non commuting SU(2) symmetries. Implications of these results could be realized in cold atoms, Josephson junction arrays and cuprate superconductors.

description: We match the Higgs sector of the most general flavour breaking and CP violating minimal supersymmetric standard model (MSSM) onto a generic two-Higgs-doublet model, paying special attention to the definition of tan beta in the effective theory. In particular no tan beta-enhanced loop corrections appear in the relation to tan beta defined in the DRbar scheme in the MSSM. The corrections to the Higgs-mediated flavour-changing amplitudes which result from this matching are especially relevant for the B_d and B_s mass differences dM_s,d for minimal flavour violation, where the superficially leading contribution vanishes. We give a symmetry argument to explain this cancellation and perform a systematic study of all Higgs-mediated effects, including Higgs loops. The corrections to dM_s are at most 7% for mu>0 and M_A < 600 if constraints from other observables are taken into account. For mu<0 they can be larger, but are always less than about 20%. Contrary to recent claims we do not find numerically large contributions here, nor do we find any tan beta-enhanced contributions from loop corrections to the Higgs potential in B^+ -> tau^+ nu or B -> X_s gamma. We further update supersymmetric loop corrections to the Yukawa couplings, where we include all possible CP-violating phases and correct errors in the literature. The possible presence of CP-violating phases generated by Higgs exchange diagrams is briefly discussed as well. Finally we provide improved values for the bag factors P^VLL_1, P^LR_2, and P^SLL_1 at the electroweak scale.

At the heart of the analysis is the proof of convergence under low regularity requirements. Numerical experiments demonstrate that the proposed method exhibits second-order convergence for smooth and robustness for rough problems.

Bias in least squares regression.
Creators: name: Williams, Douglas Harold
Publisher: name: University of British Columbia
Year: 2011

description: Much of the data analysed by least squares regression methods violates the assumption that independent variables are known without error. Also, it has been demonstrated that parameter estimates based on minimum residual sums of squares have a high probability of being unsatisfactory if the independent variables are not orthogonal. Both situations are examined jointly by Monte Carlo simulation and bias in least squares estimate of regression coefficients and error sums of squares is demonstrated. Techniques for regression under these conditions are reviewed but the literature does not present a practical algorithm in either case.
Investigating the motivations for non-suicidal self-injury and interpersonal conflict in individuals with and without borderline characteristics
Creators: name: Jammet, J
Publisher: name: University Of Tasmania
Year: 2023

description: The aim of the study was to explore the differences in the psychophysiological and subjective responses to non-suicidal self-injury (NSSI) and interpersonal conflict (IC) of individuals with and without Borderline Personality Disorder (BPD) characteristics. Specifically, this study aimed to provide further evidence for a potential self-stimulatory function of NSSI and to extend the findings to interpersonal relationships for those with BPD. A personalised staged guided imagery methodology was used to investigate processes at the time of NSSI and IC. Contrary to expectations, the results indicated that interpersonal conflict was generally associated with higher arousal and more distress for both groups. However, and not as expected, only the BPD group reported significantly higher tension during the incident stage of IC than during NSSI. This finding is consistent with prior reports that individuals with borderline personalities have increased emotional reactivity to interpersonal distress. In contrast, subjective responses to NSSI revealed a significant tension reduction following the self-injurious act. This tension reduction model was only significantly evident for the BPD group, therefore and as not expected, providing further support for the affect regulatory function of NSSI in adults with borderline characteristics.
The effects of task complexity and response probability on response latency
Creators: name: Ryan, Mark William John
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of the investigation was to study the joint effects of response probability and task complexity on response latency in simple and choice reaction time tasks. Sixteen, volunteer, University of British Columbia Physical Education students performed all four experimental conditions, one simple reaction time task and three choice reaction time tasks. Response latencies for 800 trials were obtained from each subject. Analysis of variance for a repeated measures design was used to analyse the data, with Harter and Newman-Keuls post-hoc multiple comparisons performed to test for significant differences between conditions. The empirical findings were generally not in agreement with the predicted hypotheses. It was found that very fast response latencies were made to complex tasks combined with low probability of occurrence. Subjects were also better prepared to initiate a response to an easy task with a low response probability than an easy task with a high response probability. It appears that subjects adopted a defensive type of strategy and that low response probability has more effect than high response probability on response latencies of choice reaction time tasks of unequal complexity.

description: Measurements of the polar Kerr effect using a zero-area-loop Sagnac magnetometer on Pb/Ni and Al/(Co-Pd) proximity-effect bilayers show unambiguous evidence for the "inverse proximity effect," in which the ferromagnet (F) induces a finite magnetization in the superconducting (S) layer. To avoid probing the magnetic effects in the ferromagnet, the superconducting layer was prepared much thicker than the light's optical penetration depth. The sign and size of the effect, as well as its temperature dependence agree with recent predictions by Bergeret et al..

Besides the standard PoA and PoS, which are based on Nash equilibrium, we also take into account the strong Nash equilibrium, and several other new equilibria. For each equilibrium, the corresponding PoA and PoS are given, and the problems of computing an arbitrary equilibrium, as well as approximating the best one, are also considered.

description: We study estimation of a multivariate function $f:\mathbf{R}^d\to\mathbf{R}$ when the observations are available from the function $Af$, where $A$ is a known linear operator. Both the Gaussian white noise model and density estimation are studied. We define an $L_2$-empirical risk functional which is used to define a $δ$-net minimizer and a dense empirical risk minimizer. Upper bounds for the mean integrated squared error of the estimators are given. The upper bounds show how the difficulty of the estimation depends on the operator through the norm of the adjoint of the inverse of the operator and on the underlying function class through the entropy of the class. Corresponding lower bounds are also derived. As examples, we consider convolution operators and the Radon transform. In these examples, the estimators achieve the optimal rates of convergence. Furthermore, a new type of oracle inequality is given for inverse problems in additive models.

description: We investigate the spatially dependent relative phase evolution of an elongated two-component Bose-Einstein condensate. The pseudospin-1/2 system is comprised of the |F=1,m_F=-1> and |F=2,m_F=+1> hyperfine ground states of 87Rb, which we magnetically trap and interrogate with radio-frequency and microwave fields. We probe the relative phase evolution with Ramsey interferometry and observe a temporal decay of the interferometric contrast well described by a mean-field formalism. Inhomogeneity of the collective relative phase dominates the loss of interferometric contrast, rather than decoherence or phase diffusion. We demonstrate a technique to simultaneously image each state, yielding subpercent variations in the measured relative number while preserving the spatial mode of each component. In addition, we propose a spatially sensitive interferometric technique to image the relative phase.

The creation of a new Australian repertoire for the saxophone utilising multiphonics
Creators: name: Schr‚àö‚àÇder, F
Publisher: name: University Of Tasmania
Year: 2023

description: The principal aim of this project is to stimulate and facilitate the creation of a new Australian saxophone repertoire utilising multiphonics. This dissertation will begin by examining the theoretical context of multiphonics, discussing their nature, physics and history in the saxophone repertoire. Although there are different ways of producing multi phonics, this paper will focus on producing multiphonics using special fingerings. Next, prerequisites for the production of multiphonics and methods of utilising them will be addressed. The dissertation will then outline ways in which I collaborated with Australian composers in order to facilitate the composition of new works containing multiphonics. Finally, I will discuss the resultant works, examining how multiphonics were applied by Australian composers. The scores are included as appendices to this dissertation, together with recordings of the new works. The motivation for doing this project arises in part from a personal interest in multiphonics, since they have played an integral role in my own development as a saxophonist. I have found that acquiring the ability to use multiphonics greatly enhances a saxophonist's development and versatility, as multi phonic production draws upon multiple skills. The new works that are created through this project may provide a foundation for the teaching of multiphonics and, therefore, the acquisition of such skills.

description: An accurate description of the nuclear response functions for neutrino scattering in the Gev region is essential for the interpretation of present and future neutrino oscillation experiments. Due to the close similarity of electromagnetic and weak scattering processes, we will review the status of the scaling approach and of relativistic modeling for the inclusive electron scattering response functions in the quasielastic and $Δ$-resonance regions. In particular, recent studies have been focused on scaling violations and the degree to which these imply modifications of existing predictions for neutrino reactions. We will discuss sources and magnitude of such violations, emphasizing similarities and differences between electron and neutrino reactions.

description: Excerpts from the report: The outlook for world wheat production, not only for 1930 but for some years ahead, and many important facts should be considered by wheat producers in the United States in planning their production. Facts as to the trends of prices, acreage, production, and consumption of wheat, and the factors affecting these, are presented to show the basis for the conclusion presented in the outlook statement. Extensive adjustment in wheat growing, including substantial reduction in cost per bushel, must be made if wheat production is to be profitable to growers generally in the next 6 to 10 years. This is necessary to meet intensified competition in world markets, due to increasing production in this and other countries without a corresponding increase in effective demand.

description: This note deals with stiffness tensors measured from anisotropic linear elastic materials, whose symmetry is unknown. Their possible symmetries (exact or approximative) are revealed by a pole figure. An intrinsic function allows one to obtain a stiffness tensor which posses the chosen symmetry, the nearest from the measured tensor, and its associated natural symmetry basis. For each symmetry level, a distance between these tensors is given. The measurement of the stiffness tensor is done with an ultrasonic direct contact method. It is applied onto a 26 faces oak specimen.

Becoming Emblematic : lessons from a mediatized megaproject conflictin Chile
Creators: name: Mocatta, Marie-Gabrielle
Publisher: name: University Of Tasmania
Year: 2023

description: The construction of megaprojects ‚Äö- large, landscape transforming infrastructure projects ‚Äö- is booming. Megaprojects are becoming more immense and more environmentally damaging. Requiring vast, often transnational investment, megaprojects have escaped the boundaries of the nation state, and are often enacted in transnational contexts. Research has shown that megaprojects almost always rely on a combination of overstated benefits and underestimated environmental impacts in order to be approved, attract investment, and be built. Megaprojects therefore typically rely on highly targeted strategic communications and attempts to steer public discourse, in order to emphasize their advantages and downplay risks. This leads to accusations that they are insufficiently transparent, even deceptive. However, in a hyper-connected world, megaprojects and their risks are now more visible than ever, and are increasingly contested in local, national and global public arenas. Megaprojects are constructed in discourse both by project developers and their supporters, and by protest groups, as well as through their representation in the media. During the protracted communicational sparring that often accompanies them, megaprojects can become conferred with symbolic meaning. This case study reveals the mediatized construction of a Chilean energy megaproject over eleven years from the project's inception, to its final dissolution. The proposed HidroAysen hydroelectric scheme for Patagonia was at first a largely invisible project, unknown outside the potentially affected region, until protest made the project visible. Presented by the developing company and by authorities as a nation building project to bring Chile energy independence, over time it garnered such vehement opposition that it sparked the largest protests that Chile had seen since its return to democracy. By analysing discourse in influential print and social media during the debate, using interviews with key actors, and strategic communications material from both sides, this study traces the discourse over the megaproject through several key stages. It shows what the symbolic communication of HidroAysen led the megaproject to represent, arguing that when a megaproject becomes layered with multiple symbolic meanings over time, it can become emblematic: a situation which is hard to shift. Though this study focuses on the case of one megaproject in Chile ‚Äö- and indeed shows how the nation was changed by the HidroAysen debate ‚Äö- it also draws wider lessons from the emblematic case of HidroAysen, enabling a better understanding of the communicational unfolding of transnational megaprojects, and the frequently transnational protests that oppose them.

description: We study the three-player Prisoner's Dilemma game under the effect of decoherence and correlated noise. It is seen that the quantum player is always better off over the classical players. It is also seen that the game's Nash equilibrium does not change in the presence of correlated noise in contradiction to the effect of decoherence in multiplayer case. Furthermore, it is shown that for maximum correlation the game does not behave as a noiseless game and the quantum player is still better off for all values of the decoherence parameter p which is not possible in the two-player case. In addition, the payoffs reduction due to decoherence is controlled by the correlated noise throughout the course of the game.

description: We investigate the constraints on Supersymmetry arising from available precision measurements using a global fit approach. When interpreted within minimal supergravity (mSUGRA), the data provide significant constraints on the masses of supersymmetric particles, which are predicted to be light enough for an early discovery at the Large Hadron Collider (LHC). We provide predicted mass spectra including, for the first time, full uncertainty bands. The most stringent constraint is from the measurement of the anomalous magnetic moment of the muon. Using the results of these fits, we investigate to which precision mSUGRA and more general MSSM parameters can be measured by the LHC experiments with three different integrated luminosities for a parameter point which approximately lies in the region preferred by current data. The impact of the already available measurements on these precisions, when combined with LHC data, is also studied. We develop a method to treat ambiguities arising from different interpretations of the data within one model and provide a way to differentiate between values of different digital parameters of a model. Finally, we show how measurements at a linear collider with up to 1 TeV centre-of-mass energy will help to improve precision by an order of magnitude.

The effect of proprioceptive feedback and delay interval on timing motor responses
Creators: name: Morrison, Winson Gilbert
Publisher: name: University of British Columbia
Year: 2011

description: The problem was to ascertain the effect of proprioceptive feedback developed from an initial movement; and the effect of time delay between the termination of the initial movement and the beginning of the following motor response on the temporal accuracy and consistency of that response. Thirty male Ss were randomly assigned, three to each of the ten experimental conditions composed of two levels of proprioceptive feedback (small and large) and five levels of time delay (0.3, 0.6, 1.0, 2.0 and 4.0 seconds). In the minimal proprioceptive feedback condition, the proprioceptive feedback was manipulated in the right index finger of the S by the press-release of a response-button whereas in the proprioceptive feedback condition, it was manipulated in the right arm of the S by a passively induced and consistent movement of that limb. Both, of these sources of proprioceptive feedback ended immediately prior to the beginning of the time delay interval. It was the task of the S to lift his left index finger from the response-button after the delay interval under which he was timing had elapsed. Each S was given 50 trials with knowledge of results (his exact response time in milliseconds) on each trial and with an intertrial interval of 30 seconds. The results of the analyses showed the following: one, that the Ss learned to time the motor response within the first ten trials under the influence of knowledge of results; two, that proprioceptive feedback had no effect on the accuracy and consistency of the timing of the motor response; and last, that the time delay interval had a highly significant effect on the accuracy and consistency of the timing of the motor response where the accuracy and consistency of the timing of the motor response appear to be similar power functions of the time delay interval.

description: Excerpts from the report: How much water will the farmer in the West have for his crops? How much will be available for industry and for power? Will floods be a problem? Answers to these questions come from measuring the snow on the watersheds. In the West much of the streamflow comes from melting snow on the high mountainous watersheds. The best way to forecast the amount is to measure the snow. Since it is not practical to measure all the snow in a watershed, snow surveyors take a series of samples at key locations to measure the depth and water content of the snow.

description: We investigated the non-thermal hard X-ray emission in the Ophiuchus cluster of galaxies. Our aim was to characterise the physical properties of the non-thermal component and its interaction with the cosmic microwave background. We performed spatially resolved spectroscopy and imaging using XMM-Newton data to model the thermal emission. Combining this with INTEGRAL ISGRI data, we modeled the 0.6-140 keV band total emission in the central 7 arcmin region. The models that best describe both PN and ISGRI data contain a power-law component with a photon index in a range 2.2-2.5. This component produces ~10% of the total flux in the 1-10 keV band. The pressure of the non-thermal electrons is ~1% of that of the thermal electrons. Our results support the scenario whereby a relativistic electron population, which produces the recently detected radio mini-halo in Ophiuchus, also produces the hard X-rays via inverse compton scattering of the CMB photons. The best-fit models imply a differential momentum spectrum of the relativistic electrons with a slope of 3.4-4.0 and a magnetic field strength B=0.05-0.15 microG. The lack of evidence for a recent major merger in the Ophiuchus center allows the possibility that the relativistic electrons are produced by turbulence or hadronic collisions.

description: We study (bi)simulation-like preorder/equivalence checking on the class of visibly pushdown automata and its natural subclasses visibly BPA (Basic Process Algebra) and visibly one-counter automata. We describe generic methods for proving complexity upper and lower bounds for a number of studied preorders and equivalences like simulation, completed simulation, ready simulation, 2-nested simulation preorders/equivalences and bisimulation equivalence. Our main results are that all the mentioned equivalences and preorders are EXPTIME-complete on visibly pushdown automata, PSPACE-complete on visibly one-counter automata and P-complete on visibly BPA. Our PSPACE lower bound for visibly one-counter automata improves also the previously known DP-hardness results for ordinary one-counter automata and one-counter nets. Finally, we study regularity checking problems for visibly pushdown automata and show that they can be decided in polynomial time.

description: We present a bijection between some quadrangular dissections of an hexagon and unrooted binary trees, with interesting consequences for enumeration, mesh compression and graph sampling. Our bijection yields an efficient uniform random sampler for 3-connected planar graphs, which turns out to be determinant for the quadratic complexity of the current best known uniform random sampler for labelled planar graphs [{\bf Fusy, Analysis of Algorithms 2005}]. It also provides an encoding for the set $\mathcal{P}(n)$ of $n$-edge 3-connected planar graphs that matches the entropy bound $\frac1n\log_2|\mathcal{P}(n)|=2+o(1)$ bits per edge (bpe). This solves a theoretical problem recently raised in mesh compression, as these graphs abstract the combinatorial part of meshes with spherical topology. We also achieve the {optimal parametric rate} $\frac1n\log_2|\mathcal{P}(n,i,j)|$ bpe for graphs of $\mathcal{P}(n)$ with $i$ vertices and $j$ faces, matching in particular the optimal rate for triangulations. Our encoding relies on a linear time algorithm to compute an orientation associated to the minimal Schnyder wood of a 3-connected planar map. This algorithm is of independent interest, and it is for instance a key ingredient in a recent straight line drawing algorithm for 3-connected planar graphs [\bf Bonichon et al., Graph Drawing 2005].

description: We introduce an analytically solvable model of two-dimensional continuous attractor neural networks (CANNs). The synaptic input and the neuronal response form Gaussian bumps in the absence of external stimuli, and enable the network to track external stimuli by its translational displacement in the two-dimensional space. Basis functions of the two-dimensional quantum harmonic oscillator in polar coordinates are introduced to describe the distortion modes of the Gaussian bump. The perturbative method is applied to analyze its dynamics. Testing the method by considering the network behavior when the external stimulus abruptly changes its position, we obtain results of the reaction time and the amplitudes of various distortion modes, with excellent agreement with simulation results.

description: We study Wilson-'t Hooft loop operators in a class of N=2 superconformal field theories recently introduced by Gaiotto. In the case that the gauge group is a product of SU(2) groups, we classify all possible loop operators in terms of their electric and magnetic charges subject to the Dirac quantization condition. We then show that this precisely matches Dehn's classification of homotopy classes of non-self-intersecting curves on an associated Riemann surface--the same surface which characterizes the gauge theory. Our analysis provides an explicit prediction for the action of S-duality on loop operators in these theories which we check against the known duality transformation in several examples.

description: The COVID-19 pandemic has changed consumer grocery shopping choices and patterns. As consumers have looked for products that might boost their immune system, OJ has been seen as a convenient option to achieve this. By exploring both Nielsen grocery scanner data and a monthly consumer survey from April 2020 to March 2021, we provide a visual description of the dynamic changes in OJ consumers within the year of the pandemic.
Impacting Software Quality and Process Through the Extreme-Scale Scientific Software Stack (E4S) and Software Development Kit (SDK) Projects

Subjects: subject: Computer Software
subject: FOS: Computer and information sciences

description: The E4S and SDK projects improve quality and efficiency within the scientific software ecosystem through containerization, build caches, continuous integration (CI) testing, improving interoperability between packages, and community policies. The E4S containerization effort delivers solutions that raise productivity by providing a tested environment for development and delivering tutorials. The E4S build cache increases productivity, providing thousands of pre-built binaries for a variety of platforms. The containers and build cache also enhance the reproducibility of configurations and errors. E4S promotes the sustainability of the scientific software ecosystem through a multi-platform CI testing infrastructure. Covering many areas including development tools, math libraries, and data and visualization, individual SDKs enhance the productivity of application developers in a variety of ways, including increasing the interoperability and portability of software within the SDK, and providing an additional, complimentary layer of CI testing. Community policies at the E4S level, and SDK-specific policies promote long-term sustainability through minimal software standards in a variety of areas, including building, testing, documentation, and error handling. This talk will introduce many ways in which E4S and the SDK projects are increasing productivity, and improving sustainability and reproducibility, as well as touch on future efforts in these areas.

A talk presented at the SIAM PP22 conference, MS5+MS21: Research Challenges and Opportunities within Software Productivity, Sustainability, and Reproducibility.

description: In the Cohen-Glashow Very Special Relativity we exhibit possible modifications to the Maxwell theory and to the quantum electrodynamics Lagrangian in some generality, and discuss characteristic features depending on the modifications. Modified gauge transformations in SIM(2)-invariant theories are introduced, and in these theories gauge fields with two polarization states can have nonzero mass. Also considered are SIM(2)-covariant modifications to the Proca-type field equations for a massive spin-1 particle.

Comparative analysis of the information processing rate of the decision mechanism of retardates and normals
Creators: name: Lindsay, Janis Elaine
Publisher: name: University of British Columbia
Year: 2011

description: Eight male retarded Ss and eight male normal Ss took part in a choice reaction time experiment involving four levels of information load. The experiment required Ss to choose between two, four and six alternatives, depending on the condition being tested, and to respond by pressing the correct response button for each trial. Simple reaction time of both groups was also tested. The results obtained from the choice conditions of the experiment were tested by an analysis of variance test and a t-test was used to test the difference in simple reaction time between the two groups. The results indicated that there was a significant difference between the simple reaction of the two groups and that as information load was increased there was a significant increase in the difference in reaction time between the two groups. Also differences were found between the group variability and intra-individual variability of the two groups. The results were discussed in relation to information theory and other studies which have dealt with the reaction time differences of normals and retardates. It was concluded that retarded Ss have a slower simple reaction time than normal Ss, and that retardates process information in their decision mechanism, at a slower rate than normals. The decision mechanism of retarded Ss was cited a partial source of the delay in reaction time of retarded Ss. It was felt that further investigation is necessary to determine to what degree the decision mechanism is responsible for the slower than normal reaction times of retarded Ss.
