description: An elicitation format prevalently applied in DCE is to offer each respondent a sequence of choice tasks containing more than two choice options. However, empirical evidence indicates that repeated choice tasks influence choice behavior through institutional learning, fatigue, value learning, and strategic response. The study reported in this paper employs a split sample approach based on field surveys using a single binary elicitation format with a majority vote implementation as the baseline to expand the research on effects of sequential binary DCE formats. We provide evidence for effects caused by institutional learning and either strategic behavior or value learning after respondents answered repeated choice questions. However, we did not find any indications for strategic behavior caused by awareness of having multiple choices. The choice between a sequential and a single elicitation format may thus imply a trade-off between decreased choice accuracy and potentially increased strategic behavior due to an incentive incompatible mechanism. Further research is needed to explore strategic behavior induced by incentive incompatible elicitation formats using alternative approaches that are not compromised by a confounded baseline, that facilitate the differentiation between value learning and strategic behavior, and that allow the use of less restrictive model specifications. Such research should also investigate the effects of varying incentives induced by the order in which choice questions are presented to respondents.
Three Mechanisms for Bar Thickening

description: We present simulations of bar-unstable stellar discs in which the bars thicken into box/peanut shapes. Detailed analysis of the evolution of each model revealed three different mechanisms for thickening the bars. The first mechanism is the well-known buckling instability, the second is the vertical excitation of bar orbits by passage through the 2:1 vertical resonance, and the third is a gradually increasing fraction of bar orbits trapped into this resonance. Since bars in many galaxies may have formed and thickened long ago, we have examined the models for fossil evidence in the velocity distribution of stars in the bar, finding a diagnostic to discriminate between a bar that had buckled from the other two mechanisms.

description: A search for heavy resonances decaying into a $W$ or $Z$ boson and a Higgs boson produced in proton$-$proton collisions at the Large Hadron Collider at $\sqrt{s} = 13$ TeV is presented. The analysis utilizes the dominant $W \to q \bar{q}^\prime$ or $Z \to q \bar{q}$ and $H \to b \bar{b}$ decays with substructure techniques applied to large-radius jets. A sample corresponding to an integrated luminosity of 139 fb$^{-1}$ collected with the ATLAS detector is analyzed and no significant excess of data is observed over the background prediction. The results are interpreted in the context of the Heavy Vector Triplet model with spin-1 $W^\prime$ and $Z^\prime$ bosons. Upper limits on the cross section are set for resonances with mass between 1.5 and 5.0 TeV, ranging from 6.8 to 0.53 fb for $W^\prime \to WH$ and from 8.7 to 0.53 fb for $Z^\prime \to ZH$ at the 95 % confidence level.

description: Recent developments concerning localized-magnon eigenstates in strongly frustrated spin lattices and their effect on the low-temperature physics of these systems in high magnetic fields are reviewed. After illustrating the construction and the properties of localized-magnon states we describe the plateau and the jump in the magnetization process caused by these states. Considering appropriate lattice deformations fitting to the localized magnons we discuss a spin-Peierls instability in high magnetic fields related to these states. Last but not least we consider the degeneracy of the localized-magnon eigenstates and the related thermodynamics in high magnetic fields. In particular, we discuss the low-temperature maximum in the isothermal entropy versus field curve and the resulting enhanced magnetocaloric effect, which allows efficient magnetic cooling from quite large temperatures down to very low ones.

Validation of subclinical psychopathy via peer ratings and concrete behavior
Creators: name: Nathanson, Craig
Publisher: name: University of British Columbia
Year: 2009

description: Clinical psychopathy is characterized by cold affect, interpersonal manipulation, antisocial behavior, and impulsive thrill seeking. Recently, a similar but less extreme form of clinical psychopathy in 'normal' populations has been proposed — 'subclinical psychopathy.' Although initial work has provided some understanding of subclinical psychopathy, the construct has not been fully validated. To this end, two studies were conducted to further validate the subclinical psychopathy using peer-ratings and concrete behavior as criteria. Study 1 examined whether knowledgeable raters could identify subclinical psychopaths and distinguish them from other dark personalities. Results indicated that subclinical psychopathy emerged as a distinct construct. That is, individuals who scored high on a self-report measure of subclinical psychopathy are rated similarly by those who know them well. To bolster previous research using self-report measures, Study 2 used a concrete measure of misbehavior, namely, exam cheating. Results indicated that self-report subclinical psychopathy was a strong independent predictor of cheating independent of cognitive ability and other personality measures. Taken together, these findings suggest that subclinical psychopathy is a valid and viable construct.

description: Policy makers aiming to get private landholders to provide non-marketed environmental services need to provide efficient economic incentives. Two ideas have been explored to achieve this: linking contract payments to environmental outcomes and putting the contracts up for tender. This paper investigates whether there are any gains to be had by combining the benefits of both approaches. Landholder risk aversion may offset incentive effects if the fall in participation outweighs any increases in individual effort. Using controlled lab experiments in two countries and across four subject groups, and systematically varying the rate at which payments are linked to uncertain outcomes, this paper clarifies the conditions under which incentives overcome risk-aversion – a parameter which was also measured. Results show that for risk averse landholders the most efficient approach is in general to tender contracts only moderately linked to environmental outcomes – that is, using a balanced combination of fixed input payments and of payments linked to uncertain outcomes. This paper also highlights how experiments can complement the inherent limitations of a purely theoretical analysis.

description: La0.4Pr0.3Ca0.1Sr0.2MnO3 has been investigated as a potential candidate for room temperature magnetic refrigeration. Results from X-ray powder diffraction reveal an orthorhombic structure with Pnma space group. The electronic and chemical properties have been confirmed by X-ray photoelectron spectroscopy and ion-beam analysis. A second-order paramagnetic to ferromagnetic transition was observed near room temperature (289 K), with a mean-field like critical behaviour at low field and a tricritical mean-field like behaviour at high field. The field induced crossover in critical behaviour is a consequence of the system being close to a first-order magnetic transition in combination with a magnetic field induced suppression of local lattice distortions. The lattice distortions consist of interconnected and weakly distorted pairs of Mn-ions, where each pair shares an electron and a hole, dispersed by large Jahn-Teller distortions at Mn3+ lattice sites. A comparatively high value of the isothermal entropy-change (3.08 J/kg-K at 2 T) is observed and the direct measurements of the adiabatic temperature change reveal a temperature change of 1.5 K for a magnetic field change of 1.9 T.

description: Due to the inevitable accumulation of the observed information in the direction of the line of sight, it is difficult to measure the local magnetic field of MHD turbulence. However, the correct understanding of the local magnetic field is a prerequisite for reconstructing the Galactic 3D magnetic field. We study how to reveal the local magnetic field direction and the eddy anisotropy on the basis of the statistics of synchrotron polarization derivative with respect to the squared wavelength $dP/dλ^2$. In the low frequency and strong Faraday rotation regime, we implement numerical simulations in the combination of multiple statistic techniques, such as structure function, quadrupole ratio modulus, spectral correlation function, correlation function anisotropy and spatial gradient techniques. We find that (1) statistic analysis of $dP/dλ^2$ indeed reveals the anisotropy of underlying MHD turbulence, the degree of which increases with the increase of the radiation frequency; (2) the synergy of both correlation function anisotropy and gradient calculation of $dP/dλ^2$ enables the measurement of the local magnetic field direction.

description: We analyze the effects of trade liberalization on environmental policies in a strategic setting when there is transboundary pollution. Trade liberalization can result in a race to the bottom in environmental taxes, which makes both countries worse. This is not due to the terms of trade motive, but rather the incentive, in a strategic setting, to reduce the incidence of transboundary pollution. With command and control policies (emission quotas), countries are unable to influence foreign emissions by strategic choice of domestic policy; hence, there is no race to the bottom. However, with internationally tradable quotas, unless pollution is a pure global public bad, there is a race to the bottom in environmental policy. Under free trade, internationally nontradable quotas result in the lowest pollution level and strictly welfare- dominate taxes. The ordering of internationally tradable quotas and pollution taxes depends, among other things, on the degree of international pollution spillovers

description: Electron-phonon coupling, being one of the most important parameters governing the material evolution after ultrafast energy deposition, yet remains the most unexplored one. In this work, we applied the dynamical coupling approach to calculate the nonadiabatic electron-ion energy exchange in nonequilibrium solids with the electronic temperature high above the atomic one. It was implemented into the tight-binding molecular dynamics code, and used to study electron-phonon coupling in various elemental metals. The developed approach is a universal scheme applicable to electronic temperatures up to a few electron-Volts, and to arbitrary atomic configuration and dynamics. We demonstrate that the calculated electron-ion (electron-phonon) coupling parameter agrees well with the available experimental data in high-electronic-temperature regime, validating the model. The following materials are studied here - fcc metals: Al, Ca, Ni, Cu, Sr, Y, Zr, Rh, Pd, Ag, Ir, Pt, Au, Pb; hcp metals: Mg, Sc, Ti, Co, Zn, Tc, Ru, Cd, Hf, Re, Os; bcc metals: V, Cr, Fe, Nb, Mo, Ba, Ta, W; diamond cubic lattice metals: Sn; specific cases of Ga, In, Mn, Te and Se; and additionally semimetal graphite and semiconductors Si and Ge. For many materials, we provide the first and so far the only estimation of the electron-phonon coupling at elevated electron temperatures, which can be used in various models simulating ultrafast energy deposition in matter. We also discuss the dependence of the coupling parameter on the atomic mass, temperature and density.

description: We consider the baby-Skyrme model in the regime close to the so-called restricted baby-Skyrme model, which is a BPS model with area-preserving diffeomorphism invariance. The perturbation takes the form of the standard kinetic Dirichlet term with a small coefficient $ε$. Classical solutions of this model, to leading order in $ε$, are called restricted harmonic maps. In the BPS limit ($ε\to 0$) of the model with the potential being the standard pion-mass term, the solution with unit topological charge is a compacton. Using analytical and numerical arguments we obtain solutions to the problem for topological sectors greater than one. We develop a perturbative scheme in $ε$ with which we can calculate the corrections to the BPS mass. The leading order ($\mathcal{O}(ε^1)$) corrections show that the baby Skyrmion with topological charge two is energetically preferred. The binding energy requires us to go to the third order in $ε$ to capture the relevant terms in perturbation theory, however, the binding energy contributes to the total energy at order $ε^2$. We find that the baby Skyrmions - in the near-BPS regime - are compactons of topological charge two, that touch each other on their periphery at a single point and with orientations in the attractive channel.

description: Water quality index is an essential part of the water resources management system that is used as a numerical scale for evaluating and classifying water quality for various uses. The present study focuses on the application of the Canadian Water Quality Index (CCME WQI) to assess the water quality of the Bashar River for drinking, agricultural, aquaculture, recreational and recreational purposes, livestock, as well as the use of the Schuler diagram to assess the quality of drinking water in this river. In this study, 3 sampling sites along Bashar River and in different seasons of 1398, 4 samples were taken from each site and examined. The results showed that Bashar's river's water quality for drinking is high and medium, and in terms of aquaculture and recreation and recreation is high and good in terms of agriculture and livestock consumption. Also analysis of Schuler plots showed that the quality of the water of Bashar River in terms of drinking is in the good and medium range.

description: Studies have suggested that there is farming potential in residential buildings. However, these studies are limited in scope, require field visits and time-consuming measurements. Furthermore, they have not suggested ways to identify suitable sites on a larger scale let alone means of surveying numerous micro-locations across the same building. Using a case study area focused on high-rise buildings in Singapore, this paper examines a novel application of 3D city models to identify suitable farming micro-locations in buildings. We specifically investigate whether the vertical spaces of these buildings comprising outdoor corridors, façades and windows receive sufficient photosynthetically active radiation (PAR) for growing food crops and do so at a high resolution. We also analyze the spatio-temporal characteristics of PAR, and the impact of shadows and different weather conditions on PAR in the building. Environmental simulations on the 3D model of the study area indicated that the cumulative daily PAR or Daily Light Integral (DLI) at a location in the building was dependent on its orientation and shape, sun's diurnal and annual motion, weather conditions, and shadowing effects of the building's façades and surrounding buildings. The DLI in the study area generally increased with building's levels and, depending on the particular micro-location, was found suitable for growing moderately light-demanding crops such as lettuce and sweet pepper. These variations in DLI at different locations of the same building affirmed the need for such simulations. The simulations were validated with field measurements of PAR, and correlation coefficients between them exceeded 0.5 in most cases thus, making a case that 3D city models offer a promising practical solution to identifying suitable farming locations in residential buildings, and have the potential for urban-scale applications.

description: We employ a combination of machine learning and first-principles calculations to predict magnetic properties of rare-earth lean magnets. For this purpose, based on training set constructed out of experimental data, the machine is trained to make predictions on magnetic transition temperature (Tc), largeness of saturation magnetization (μ0Ms), and nature of the magnetocrystalline anisotropy (Ku). Subsequently, the quantitative values of μ0Ms and Ku of the yet-to-be synthesized compounds, screened by machine learning, are calculated by first-principles density functional theory. The applicability of the proposed technique of combined machine learning and first-principles calculations is demonstrated on 2-17-X magnets, Ce2Fe17-xCoxCN. Further to this study, we explore stability of the proposed compounds by calculating vacancy formation energy of small atom interstitials (N/C). Our study indicates a number of compounds in the proposed family, offers the possibility to become solution of cheap, and efficient permanent magnet.

description: We show that the problem of finding the primary and secondary characteristic directions of a linear lossless optical element can be reformulated in terms of an eigenvalue problem related to the unimodular factor of the transfer matrix of the optical device. This formulation makes any actual computation of the characteristic directions amenable to pre-implemented numerical routines, thereby facilitating the decomposition of the transfer matrix into equivalent linear retarders and rotators according to the related Poincare equivalence theorem. The method is expected to be useful whenever the inverse problem of reconstruction of the internal state of a transparent medium from optical data obtained by tomographical methods is an issue.

description: We simulate the scientific performance of the Wide-Field Infrared Survey Telescope (WFIRST) High Latitude Survey (HLS) on dark energy and modified gravity. The 1.6 year HLS Reference survey is currently envisioned to image 2000 deg$^2$ in multiple bands to a depth of $\sim$26.5 in Y, J, H and to cover the same area with slit-less spectroscopy beyond z=3. The combination of deep, multi-band photometry and deep spectroscopy will allow scientists to measure the growth and geometry of the Universe through a variety of cosmological probes (e.g., weak lensing, galaxy clusters, galaxy clustering, BAO, Type Ia supernova) and, equally, it will allow an exquisite control of observational and astrophysical systematic effects. In this paper we explore multi-probe strategies that can be implemented given WFIRST's instrument capabilities. We model cosmological probes individually and jointly and account for correlated systematics and statistical uncertainties due to the higher order moments of the density field. We explore different levels of observational systematics for the WFIRST survey (photo-z and shear calibration) and ultimately run a joint likelihood analysis in N-dim parameter space. We find that the WFIRST reference survey alone (no external data sets) can achieve a standard dark energy FoM of >300 when including all probes. This assumes no information from external data sets and realistic assumptions for systematics. Our study of the HLS reference survey should be seen as part of a future community driven effort to simulate and optimize the science return of WFIRST.

description: Australian governments spend millions of dollars each year on pre border, border and post border biosecurity programs. While the resourcing of some of these programs is determined by existing deeds of agreement, others, particularly in relation to environmental and social pests and diseases, fall outside of existing decision frameworks. This paper presents a new biosecurity investment decision framework based on economic principles that aims to produce more objectively determined decisions. It determines whether a role for government exists in relation to a specific problem through the application of market failure tests and then guides the user to the most efficient cost recovery mechanism. The framework is presently under active consideration for use by Industry & Investment NSW and would be suitable for wider application.

description: The current ACIAR (Australian Centre for International Agricultural Research) guidelines for impact assessment of agricultural development projects see impact assessment as being useful for both accountability to stakeholders and as a learning tool to find out what works, what doesn’t work and why. The methodology involves the use of conventional economic evaluation and the estimation of a money metric based on measuring outcomes in terms of economic surplus changes attributable to directed actions and activities. On the question of accountability to stakeholders, this paper suggests that the money metric may not be the best outcomes-based measure of performance against development goals and that other performance indicators ought to be considered. The paper also suggests exploring other approaches to assess accountability including qualitative (narrative) methods as well as process-based accountability. On the question of using impact assessment as a learning tool, the paper suggests this might be quite useful for more traditional non-adaptive research, but is less useful for adaptive research projects involving participatory action research (PAR). With PAR projects, learning about what works, what doesn’t work and why already occurs as an integral part of the research process. The paper concludes with some thoughts about project evaluation of an ACIAR-funded project with which the authors are involved in northwest Cambodia focusing on upland crop production and marketing.

We show that there are no anomalies in the fermionic OPE's and the complete set of compensator's equations is derived from the energy-momentum tensor. The equations of motion describe a hypertensorial and vectorial multiplet coupled to a U(1)\times U(1) N=2 Poincarè Supergravity.

Looking at Annibale Carracci’s "The Butcher Shop"
Creators: name: Campbell, Paloma Stasia
Publisher: name: University of British Columbia
Year: 2009

description: An enormous painting produced by Annibale Carracci around 1583 teems with the visceral. The assemblage of bodies represented within the enclosed space of "The Butcher Shop" proliferates in both human and animal form. I will be looking at how a multitude of spatial, bodily, and temporal transitions and displacements are produced by the intermingling of living and dead bodies that surround the wooden table displaying pieces of meat. In spite of the proliferation of flayed and hanging carcasses within the painting and the representation of labour in an apparently uninterrupted sequence of time, there is an emphatic absence of blood. This disjunction may have something to do with the fact that the painting was produced at a time when the marketplace was becoming more regulated by sanitary laws. But I will argue that while the dripping and staining of blood is not present in the painting, it is suggested in more insidious ways. Red paint figures predominantly throughout in the form of clothing and the act of vision takes on the role of blood as it infiltrates, animates, and contaminates the bodies within the representation. "The Butcher Shop" has been considered an anomaly in the work of Carracci. The size of the painting and what it represents have made it difficult to classify. All attempts to categorize it as genre confront the problem of its scale, which suggests a subject other than labour. As my thesis will show, this is not the only disjunction the painting presents. There are, in fact, a number of displacements within the painting that undermine attempts to come up with a single or stable reading of the image and what it represents. This project will consider the ways in which bodies are transformed through labour and vision. What happens when the act of butchery has been replaced by the act of painting? My contention is that paint can be seen as flesh and that its very application unsettles the clear demarcation of bodies and attempts to return them to readability. It is the paint itself that makes the bodies and activities represented indiscernible.

description: The initial $P$-invariance of the electroweak interaction Lagrangian together with the low-energy results of the Weinberg-Salam model is provided by a local secondary symmetry. Among the transformation parameters of this symmetry there are both scalars, and pseudo-scalars with respect to the orthochronous Lorentz group. Such symmetry does admissible existence of a light (massless) axial gauge boson and its possible nonuniversal interaction with the leptons of various types.

description: The electronic density of states (DOS) quantifies the distribution of the energy levels that can be occupied by electrons in a quasiparticle picture, and is central to modern electronic structure theory. It also underpins the computation and interpretation of experimentally observable material properties such as optical absorption and electrical conductivity. We discuss the challenges inherent in the construction of a machine-learning (ML) framework aimed at predicting the DOS as a combination of local contributions that depend in turn on the geometric configuration of neighbours around each atom, using quasiparticle energy levels from density functional theory as training data. We present a challenging case study that includes configurations of silicon spanning a broad set of thermodynamic conditions, ranging from bulk structures to clusters, and from semiconducting to metallic behavior. We compare different approaches to represent the DOS, and the accuracy of predicting quantities such as the Fermi level, the DOS at the Fermi level, or the band energy, either directly or as a side-product of the evaluation of the DOS. The performance of the model depends crucially on the smoothening of the DOS, and there is a tradeoff to be made between the systematic error associated with the smoothening and the error in the ML model for a specific structure. We demonstrate the usefulness of this approach by computing the density of states of a large amorphous silicon sample, for which it would be prohibitively expensive to compute the DOS by direct electronic structure calculations, and show how the atom-centred decomposition of the DOS that is obtained through our model can be used to extract physical insights into the connections between structural and electronic features.

description: Artificial intelligence (AI) has huge potential to improve the health and well-being of people, but adoption in clinical practice is still limited. Lack of transparency is identified as one of the main barriers to implementation, as clinicians should be confident the AI system can be trusted. Explainable AI has the potential to overcome this issue and can be a step towards trustworthy AI. In this paper we review the recent literature to provide guidance to researchers and practitioners on the design of explainable AI systems for the health-care domain and contribute to formalization of the field of explainable AI. We argue the reason to demand explainability determines what should be explained as this determines the relative importance of the properties of explainability (i.e. interpretability and fidelity). Based on this, we propose a framework to guide the choice between classes of explainable AI methods (explainable modelling versus post-hoc explanation; model-based, attribution-based, or example-based explanations; global and local explanations). Furthermore, we find that quantitative evaluation metrics, which are important for objective standardized evaluation, are still lacking for some properties (e.g. clarity) and types of explanations (e.g. example-based methods). We conclude that explainable modelling can contribute to trustworthy AI, but the benefits of explainability still need to be proven in practice and complementary measures might be needed to create trustworthy AI in health care (e.g. reporting data quality, performing extensive (external) validation, and regulation).
A method of effective potentials for calculating the frequency spectrum of eccentrically layered spherical cavity resonators

description: A novel method for the calculation of eigenfrequencies of non-uniformly filled spherical cavity resonators is developed. The impact of the system symmetry on the electromagnetic field distribution as well as on its degrees of freedom (the set of resonant modes) is examined. It is shown that in the case of angularly symmetric cavity, regardless of its radial non-uniformity, the set of resonator modes is, as anticipated, a superposition of TE and TM oscillations which can be described in terms of a single scalar function independently of each other. The spectrum is basically determined through the introduction of effective ``dynamic'' potentials which encode the infill inhomogeneity. The violation of polar symmetry in the infill dielectric properties, the azimuthal symmetry being simultaneously preserved, suppresses all azimuthally non-uniform modes of electric-type (TM) oscillations. In the absence of angular symmetry of both electric and magnetic properties of the resonator infill, only azimuthally uniform distribution of both TM and TE fields is expected to occur in the resonator. The comparison is made of the results obtained through the proposed method and of the test problem solution obtained with use of commercial solvers. The method appears to be efficient for computational complex algorithms for solving spectral problems, including those for studying the chaotic properties of electrodynamic systems' spectra.

description: The Fitzroy Basin is one of the largest catchment areas in Australia covering 143,000 km² and is the largest catchment for the Great Barrier Reef (GBR) lagoon. Recent research has identified that poor water quality is having negative impacts on the GBR. Grazing beef cattle is the dominant land use in the Fitzroy Basin (90% by area) and has been identified as the major contributor of sediment (~%90) and organic nutrient loads to the GBR lagoon. A bioeconomic model has been developed which determines the cost ($/tonne of sediment) incurred by graziers in implementing strategies that increase ground cover and land condition. The results demonstrate the implications of land type, grazing pressure, tree basal area and enterprise operation on optimal grazing pressure for profit and for sediment reduction. The type of enterprise operation and initial start condition have a large impact on the profit made and sediment exported. This allows the tradeoffs between beef production and sediment reduction to be explored and is a useful tool in the design of natural resource management policy and change programs. It was concluded that land initially in poor condition with a reduced grazing pressure provides the cheapest reduction in sediment export if incentive payments are the chosen policy method. However graziers who are utilizing pasture past the optimal rate will require extension actives through education to reduce grazing pressure and sediment run‐off.

description: The photo-emission of two protons from the $^{12}$C, $^{16}$O and $^{40}$Ca nuclei is investigated. Aim of the work is the study of the possibilities offered by this probe to obtain information about the characteristics of the short-range correlations. We have also evaluated the effects of the two-body $Δ$-currents which, in this processes, compete with those produced by the short-range correlations. Our results show that ($γ$,pp) processes could be more useful than (e,e'pp) for the study of the short-range correlations.
