description: A hedonic price model is applied to a cross-sectional time-series data set of Kansas wheat characteristics. Results indicate that prices received by wheat producers reflect the presence of conventional quality characteristics of wheat and also milling and dough characteristics. Furthermore, the results indicate that the alternative sets of characteristics exhibit quality information that is, to some degree, independent of one another. Important conclusions regarding the efficiency of current grading and pricing practices for wheat are drawn from this analysis.

description: We present high-precision photometry of the hypervelocity star SDSS J090745.0+024507 (HVS), which has a Galactic rest-frame radial velocity of v=709 km/s, and so has likely been ejected from the supermassive black hole in the Galactic center. Our data were obtained on two nights using the MMT 6.5m telescope, and is supplemented by lower precision photometry obtained on four nights using the FLWO 1.2m telescope. The high-precision photometry indicates that the HVS is a short-period, low-amplitude variable, with period P=0.2-2 days and amplitude A = 2-10%. Together with the known effective temperature of T_eff ~ 10,500 K (spectral type B9), this variability implies that the HVS is a member of the class of slowly pulsating B-type main sequence stars, thus resolving the previously-reported two-fold degeneracy in the luminosity and distance of the star. The HVS has a heliocentric distance of 71 kpc, and an age of ~0.35 Gyr. The time of ejection from the center of the Galaxy is < 100 Myr, and thus the existence of the OS constitutes observational evidence of a population of young stars in the proximity of the central supermassive black hole ~0.1 Gyr ago. It is possible that the HVS was a member of a binary that was tidally disrupted by the central black hole; we discuss constraints on the properties of the companion's orbit.

On the power of non-local boxes

description: A non-local box is a virtual device that has the following property: given that Alice inputs a bit at her end of the device and that Bob does likewise, it produces two bits, one at Alice's end and one at Bob's end, such that the XOR of the outputs is equal to the AND of the inputs. This box, inspired from the CHSH inequality, was first proposed by Popescu and Rohrlich to examine the question: given that a maximally entangled pair of qubits is non-local, why is it not maximally non-local? We believe that understanding the power of this box will yield insight into the non-locality of quantum mechanics. It was shown recently by Cerf, Gisin, Massar and Popescu, that this imaginary device is able to simulate correlations from any measurement on a singlet state. Here, we show that the non-local box can in fact do much more: through the simulation of the magic square pseudo-telepathy game and the Mermin-GHZ pseudo-telepathy game, we show that the non-local box can simulate quantum correlations that no entangled pair of qubits can in a bipartite scenario and even in a multi-party scenario. Finally we show that a single non-local box cannot simulate all quantum correlations and propose a generalization for a multi-party non-local box. In particular, we show quantum correlations whose simulation requires an exponential amount of non-local boxes, in the number of maximally entangled qubit pairs.

description: A new line list for hydronium (H$_3$$^{16}$O$^+$) is computed. The line list is based on a new ab initio dipole moment surface (CCSD(T)/aug-cc-pVQZ) and a new empirical potential energy surface (PES). The empirical PES of H$_3$O$^+$ was obtained by refining an ab initio surface through a global fit to the experimentally determined ro-vibrational energies collected from the literature covering the ground, $ν_1^{\pm}$, $ν_2^{\pm}$, $2ν_2^{\pm}$, $ν_3^{\pm}$ and $ν_4^{\pm}$ vibrational states. The line list covers the wavenumber range up to 10 000 cm$^{-1}$ (wavelengths $>1 μ$m) and should be complete for temperatures up to $T=1500$ K. This is the first comprehensive line list for H$_3$O$^+$ with extensive wavenumber coverage and accurate transitional probabilities. Prospects of detection of hydronium in spectra of solar system giant planets as well as exoplanets are discussed. The eXeL line list is publicly available from the ExoMol and CDS databases.
WHEN IS EXPENDITURE "EXOGENOUS" IN SEPARABLE DEMAND MODELS?

Year: 1991
Subjects: Demand and Price Analysis

description: The separability hypothesis and expenditure as an exogenous variable in a system of conditional demands are analyzed. Expenditure cannot be weakly exogenous in a system of conditional demands specified as functions of the prices of the separable goods and total expenditure on those goods. Furthermore, expenditure is uncorrelated with the residuals of the conditional demand equations only when severe restrictions are satisfied. Therefore, expenditure will seldom be strictly exogenous. Econometric methods are presented for the consistent and efficient estimation of the unknown parameters when expenditures is correlated with the residuals and when it is not.

description: One of the most important advantages of the semantic differentiatial tool developed by Osgood is that it makes it possible to highlight the unconscious determinants of social practices, by adopting an indirect method of investigation. Despite its limited use in the social sciences, it remains less used in psychology than in the fields of marketing and economics, but the importance of the results cannot be neglected and they are fully adaptable to sociology and other areas.This little-known tool deserves to be approached theoretically by explaining its origin and its development within the Osgood team in the 1950s. We will show how to use this tool, modify the method of questioning, presentation and interpretation results, and some of its applications in the field of motor skills.Its multiple possibilities of use in many fields give this tool a wide application which undoubtedly allows us to patiently explore the psychosocial aspects still hidden in the field of games and sport. Through this article, we will try to facilitate the understanding and explanation of the tool, while supporting it by mentioning some intercultural studies which were carried out by members of the JPL research team in Paris, under the direction of Professor Pierre Parlebas, whose current work is part of it. These studies aimed to determine the importance of certain sports and games and to study the possible relationship between their structures and the pleasure of action.

description: The ExoMol database (www.exomol.com) provides molecular data for spectroscopic studies of hot atmospheres. While the data is intended for studies of exoplanets and other astronomical bodies, the dataset is widely applicable. The basic form of the database is extensive line lists; these are supplemented with partition functions, state lifetimes, cooling functions, Landé g-factors, temperature-dependent cross sections, opacities, pressure broadening parameters, $k$-coefficients and dipoles. This paper presents the latest release of the database which has been expanded to consider 80 molecules and 190 isotopologues totaling over 700 billion transitions. While the spectroscopic data is concentrated at infrared and visible wavelengths, ultraviolet transitions are being increasingly considered in response to requests from observers. The core of the database comes from the ExoMol project which primarily uses theoretical methods, albeit usually fine-tuned to reproduce laboratory spectra, to generate very extensive line lists for studies of hot bodies. The data has recently been supplemented by line lists deriving from direct laboratory observations, albeit usually with the use of ab initio transition intensities. A major push in the new release is towards accurate characterisation of transition frequencies for use in high resolution studies of exoplanets and other bodies.

description: South Korea uses a quota and a tariff on beef imports to keep farm prices high. Part of the quota rents are used to support indirect benefits to producers. The welfare costs of these policies are analyzed. Following a suggestion of Hayami, a deficiency payment financed by tariff revenues from increased imports is considered as an alternative to the quota. As Anderson (1983) found for Japan, a deficiency payment is Pareto-superior only if indirect benefits from the quota revenue are ignored.

description: Interaction of the electron spin with local elastic twists due to transverse phonons has been studied. Universal dependence of the spin relaxation rate on the strength and direction of the magnetic field has been obtained in terms of the electron gyromagnetic tensor and macroscopic elastic constants of the solid. The theory contains no unknown parameters and it can be easily tested in experiment. At high magnetic field it provides parameter-free lower bound on the electron spin relaxation in quantum dots.

description: SDSS J0924+0219 is the most glaring example of a gravitational lens with anomalous flux ratios: optical broad-band photometry shows image D to be a factor of 12 fainter than expected for smooth lens potentials. We report spectroscopy showing that the anomaly is present in the broad emission line flux ratios as well. There are differences between the emission line and continuum flux ratios: the A/D ratio is 10 in the broad Lyman-alpha line and 19 in the associated continuum. Known variability argues for the presence of microlensing. We show that microlensing can account for both the continuum and emission line flux ratios, if the broad emission line region is comparable in size to the Einstein radii of the microlenses. Specifically, we need the half-light radius of the broad-line region to be R_BLR

description: Coherent two-dimensional spectroscopy in IR or visible region is very effective for studying correlations, energy relaxation/transfer pathways in complex multi-chromophore or multi-mode systems. However it is usually restricted up to two-quanta excitations and their properties. In this paper an arbitrary level of excitation is suggested as the utility to scan nonlinear potential surfaces of quantum systems up to a desired excitation degree. This can be achieved by a simple three-pulse laser spectroscopy approach. Accurate evaluation of high-level anharmonicities as well as transition amplitudes can be directly obtained. Additionally, questions regarding the quantum nature of the probed system can be addressed by studying absolute peak positions.

description: This article examines the effects of different income and food spending adult equivalence scales on estimated expenditure elasticities, on the demographic characteristics of the rich and poor, and on the percentage of household income spent on food by various income quintiles. Empirical results are found to be heavily influenced by the choice of equivalence scales. For example, elasticities varied by over 300%, and the demographic characteristics of the poor varied greatly.

description: The feeder cattle futures contract specifications were changed in 1986 from physical delivery to cash settlement. The Chicago Mercantile Exchange expected this change to reduce basis variability and improve the ability of hedgers to predict basis. This study analyzes the basis for individual lots of feeder cattle before and after cash settlement. Basis equations were estimated by breed, sex, weight, grade, and season. These equations were used to predict basis. The results indicate basis variability was not reduced and hedger ability to forecast basis, in general, was not improved significantly under cash settlement compared to physical delivery.

description: We have many routes to success in agricultural economics: extension education, resident teaching, advising, research, and public service. In selecting problems to study we must be sensitive to needs of all our clientele. Several production economics concepts are relevant to allocating our own efforts. Noticing, recognizing, and experiencing surprise aid scientific discovery. We need to use heuristics, intuition, deduction, and induction, though consideration of science's ideal and real types shows that all these mental processes are fallible. We need special theories that have broad application. Replication deserves high priority. A few thoughts on the manuscript review process are presented.

description: We study microlensing of the faint images that form close to the centers of strong gravitational lens galaxies. These central images, which have finally begun to yield to observations, naturally appear in dense stellar fields and may be particularly sensitive to fine granularity in the mass distribution. The microlensing magnification maps for overfocussed (i.e., demagnified) images differ strikingly from those for magnified images. In particular, the familiar "fold" and "cusp" features of maps for magnified images are only present for certain values of the fraction, f, of the surface mass density contained in stars. For central images, the dispersion in microlensing magnifications is generally larger than for normal (minimum and saddle) images, especially when the source is comparable to or larger than the stellar Einstein radius. The dispersion depends in a complicated way on f; this behaviour may hold the key to using microlensing as a probe of the relative densities of stars and dark matter in the cores of distant galaxies. Quantitatively, we predict that the central image C in PMN J1632-0033 has a magnification dispersion of 0.6 magnitudes for Rsrc/Rein

description: We investigate how confinement may drastically change both the probability density of the first-encounter time and the related survival probability in the case of two diffusing particles. To obtain analytical insights into this problem, we focus on two one-dimensional settings: a half-line and an interval. We first consider the case with equal particle diffusivities, for which exact results can be obtained for the survival probability and the associated first-encounter time density over the full time domain. We also evaluate the moments of the first-encounter time when they exist. We then turn to the case when the diffusivities are not equal, and focus on the long-time behavior of the survival probability. Our results highlight the great impact of boundary effects in diffusion-controlled kinetics even for simple one-dimensional settings, as well as the difficulty of obtaining analytic results as soon as translational invariance of such systems is broken.

description: According to the monetary neutrality hypothesis, only the unanticipated money supply growth has impacts on real economic variables, and the anticipated money supply growth has no real impacts. The monetary neutrality hypothesis is tested on real farm output. The test procedure involves joint estimation of farm output and the money growth equation. The empirical results show that the anticipated money supply growth does have significant effects on farm output and, thus, do not support the monetary neutrality hypothesis.

description: In Light is a one-act monodrama in five scenes, scored for soprano, flute, guitar, percussion and electronics. The libretto was written by the composer, and is an adaptation of Peitho and the Night by Hannah Kenah. The work was premiered by Jaimie Lowe, Kenzie Slottow, Thomas Echols, Jordan Walsh, and Michael Zapruder at the B. Iden Payne Theater on April 18, 2019. Lighting design is integral to the full realization of In Light, and as such, the piece aims to present an attractive challenge to light artists for whom opportunities to share the foreground in theatrical works may be somewhat rare. In Light tells the story of Hilde, a young woman who spontaneously develops a quantum-accurate sense of light. Through this story, In Light aims to create a space in which the audience might experience light – natural scientific light – anew, as if for the first time. By creating a sonic, visual and narrative space in which quantum effects collide with the ordinary world, In Light explores stark differences between the discontinuous, indeterminate reality of light at the quantum level and the linear, narrative sense of self that humans experience. This paper traces the creation of In Light from initial concepts, through the creation of the story, libretto, and music; and it contains a musical analysis of the work.

description: We investigate neutrino mass generation scenarios where the lepton number breaking new physics couples only to the Standard Model (SM) right-handed charged lepton chirality. The lowest-order lepton number violating effective operator which describes this framework is a unique dimension nine operator involving SM gauge fields, $\mathcal{O}_9$. We find that there are two possible classes of new physics scenarios giving rise to this $\mathcal{O}_9$ operator. In these scenarios neutrino masses are induced radiatively via dark matter interactions, linking the dark matter to a natural explanation for the smallness of neutrino masses compared to the electroweak scale. We discuss the phenomenology and existing constraints in the different neutrino mass models within each class. In particular, we analyze the important interplay between neutrino mixing and neutrinoless double $β$-decay in order to predict characteristic signatures and disfavour certain scenarios.

An HST Search for Substellar Companions in the Young Cluster IC 348

description: We present the results of a HST WFPC2 search for substellar companions to members of the star-forming cluster IC 348. The detection limits for companions to low-mass stars and brown dwarfs in the PC images are dm_791=0, 2.5, and 5.5 at separations of 0.05", 0.1", and 0.3", respectively, which correspond to M_2/M_1=1, 0.3, and 0.1 at 15, 30, and 90 AU. Meanwhile, for heavily saturated solar-mass primaries in the WFC images, the limits are dm_791=0 and 6 (M_2/M_1=1 and 0.04) at 0.2" and 0.4". The sky limiting magnitude of m_791~26 at large separations from a primary corresponds to a mass of ~0.006 M_sun. For the two faintest candidate companions appearing in these data, we have obtained 0.8-2.5 um spectra with SpeX at the IRTF, which we classify as cluster members with spectral types near M6, corresponding to masses of ~0.1 M_sun. Thus, no probable substellar companions are detected in this survey. The frequencies of stellar and substellar companions within 0.4-5" (120-1600 AU) from low-mass stars in IC 348 agree with measurements in the field. The factor of ~3-10 deficiency in brown dwarfs relative to stars among companions at wide separations in IC 348 and across the much larger range of separations probed for field stars is equal within the uncertainties to the deficiency in brown dwarfs in measurements of mass functions of isolated objects. In other words, when defined relative to stars, the brown dwarf "desert" among companions is also present among isolated objects, which is expected if stellar and substellar companions form in the same manner as their free-floating counterparts. Meanwhile, among the 14 substellar primaries in our survey of IC 348, no companions are detected. This absence of wide binary brown dwarfs is statistically consistent with the frequency of wide binary stars in IC 348.

description: Two different methods of incorporating advertising effects into Almost Ideal Demand Systems (AIDS) are presented. Both advertising schemes are designed to allow theoretical restrictions to hold globally rather than at particular sample points. The models are estimated for California figs, prunes, and raisins. Empirical results indicate that generic advertising effects for these three dried fruits are generally weak when compared to price and total expenditure effects. Estimated cross-commodity effects also are relatively small except for the negative effect of raisin advertising on the quantity of prunes demanded.
Listening with the heart : learner and facilitator perspectives on intercultural training
Creators: name: Margolis, Rhonda L.
Publisher: name: University of British Columbia
Year: 2009

description: This study explores the effects of intercultural training from the perspectives of learners and facilitators. Three central questions are addressed: How does participation in an intercultural studies program affect the way learners approach intercultural interactions? How do learners engage learning between the educational and practice contexts? What are the implications for program planning? In-depth interviews were conducted with eleven learners and eight facilitators from a certificate program in intercultural studies at a Canadian university. The program is delivered through a combined on-site and online format. With its emphasis on practice-based learning, this program offered a unique opportunity to explore learner change and the application of learning in the workplace. This study was undertaken to inform program planning for intercultural training. The conceptual resources that guided the study are frameworks for program planning and transfer of learning. Perceived learner change as a result of training is explored through multiple lenses of transfer, including application (engaging and creating knowledge in practice) and diffusion (sharing ideas with others formally and informally in the workplace). Factors that contribute to engagement of learning between the practice and training contexts include the integration of theory and practice and the building of an online learning community. The study explores the concept of emotional safety, the impact of identity and representation on intercultural interactions within the training context, and the challenges of facilitating difficult dialogues related to race, power and identity. This study is situated within the larger context of the field of intercultural training. This is contested terrain comprised of two major streams: international and domestic training. Domestic training is represented by three frameworks: diversity, multicultural and anti-racism training. The study indicates that learning is influenced by the degree to which analyzing power or respecting differences is emphasized in the exploration of intercultural interactions. The study concludes with suggested reflective questions for planners of intercultural programs.

description: We present a first analysis of auction markets for specialty food products. We identify auction prices, trade volume and value for domestic and foreign origin specialty ham with geographical indications (GIs) which were actually sold in online auctions in Germany within a one-month period. Applying hedonic modeling, we examine potential factors that may influence online bidding behavior and final auction prices. We estimate positive auction price effects for weight, bidding activity, and auction length, that the domestic product is sold at a discount, that higher shipping cost have a negative impact on final prices, and that auctions ending on Fridays and Saturdays yield lower prices. The model may be used to estimate the value of GIs. In our example, we estimate relative price differences of 20-30% for the GIs of three specialty hams (Prosciutto di Parma, Jamon Serrano, Schwarzwalder).

description: Developing countries' small-scale farmers lack access to financial services. In the Eritrean Savings and Micro- Credit program (SMCP), solidarity groups are jointly responsible for individual members' loans; this reduces transaction costs, improves repayment and substitutes for collateral. Performance of SMCP (1996 to 2002) indicates low arrears and good repayment, but not satisfactory saving mobilization. SMCP service reached many people previously without access to financial services, thus materially improving individuals' economic self-confidence and independence, cash holdings and household living standards. It has had favourable social spin-offs; a well-designed village-banking model can help solve economic problems of the poor.

description: We use analytical methods to investigate a continuous vaccination strategy effects on the infectious disease dynamics in a closed population and a demographically open population. The methodology and key assumptions are based on Breda et al (2012). We show that the cumulative force of infection for the closed population and the endemic force of infection in the demographically open population can be reduced significantly by combining two factors: the vaccine effectiveness and the vaccination rate. The impact of these factors on the force of infection can transform an endemic steady state into a disease-free state.

description: The thermal behaviour of the 309-atom Lennard-Jones cluster, whose structure is a complete Mackay icosahedron, has been studied by parallel tempering Monte Carlo simulations. Surprisingly for a magic number cluster, the heat capacity shows a very pronounced peak before melting, which is attributed to several coincident structural transformation processes. The main transformation is somewhat akin to surface roughening, and involves a cooperative condensation of vacancies and adatoms that leads to the formation of pits and islands one or two layers thick on the Mackay icosahedron. The second transition in order of importance involves a whole scale transformation of the cluster structure, and leads to a diverse set of twinned structures that are assemblies of face-centred-cubic tetrahedra with 6 atoms along their edges, i.e., one atom more than the edges of the 20 tetrahedra that make up the 309-atom Mackay icosahedron. A surface reconstruction of the icosahedron from a Mackay to an anti-Mackay overlayer is also observed, but with a lower probability.

Subjects: Resource /Energy Economics and Policy

description: Drought is a recurring reality in many parts of the Sub-Saharan Africa, where agriculture continues to be a major sector of most economies, and being predominantly rain-fed, is highly prone to drought. Drought thus gives challenges to economic management at all levels, from households, to governments at all levels, other concerned agencies, local NGOs, external donors, and international organizations involved in disaster relief provision. Dealing with drought has long been a key element of policy making in SSA but the poor outcomes of drought experience in many situations mean that there is yet far to go in refining drought management to avoid the suffering from hunger and starvation. Much contemporary effort is being focused novel instruments that may enrich the policy agenda and mainstream drought preparedness in the broader development strategy. It is important to adopt a comprehensive drought risk management strategy, and shift from a crisis management mode to ex-ante strategic interventions.

description: Population pressures and the need to optimize the use of limited available land has led to increasing cropping affluence levels within the maize agro-ecologies in Kenya, and a shift from large to smallholder intensification and multiple cropping patterns. Using a geographic information system, this study relates cropping patterns, by area share, maize productivity and household incomes across maize agro-ecologies, with the purpose to establish a decision support system for optimizing land allocation and in priority setting for introduction of new technologies such as Bt maize varieties. Results show that land use patterns and maize productivity in maize farming systems differ between agroecological zones. The high potential areas experience high maize yields, with maize grown alongside major cash crops such as tea and coffee. In contrast, lowland coastal strip and lake Victoria region tend to grow drought tolerant tuber crops (such as cassava and sweet potatoes) alongside maize in appreciable land sizes. Similarly the dry areas grow drought tolerant legumes such as pigeon pea alongside maize. These low potential areas thus concentrate on meeting their subsistence food self-sufficiency needs, pointing at risk management strategies against drought and pests such as stem borer, unlike high potential areas with high value cash crops. Maize breeders should therefore consider insertion of Bt- genes in maize varieties that would achieve high production and which are also capable of safely growing side by side with crops that meet different food security conditions in different agro-ecological zones in Kenya.
Consistent ADD scenario with stabilized extra dimension

description: A model with one compact extra dimension and a scalar field of Brans-Dicke type in the bulk is discussed. It describes two branes with non-zero tension embedded into the space-time with flat background. This setup allows one to use a very simple method for stabilization of the size of extra dimension. It appears that the four-dimensional Planck mass is expressed only through parameters of the scalar field potentials on the branes.

Giant nonlinear photocurrent in $\mathcal{PT}$-symmetric magnetic topological quantum materials

description: Nonlinear photocurrent in time-reversal invariant noncentrosymmetric systems have attracted substantial interest. Here we propose two new types of second-order nonlinear direct photocurrent as the counterpart of normal shift photocurrent (NSC) and normal injection photocurrent (NIC), namely magnetic shift photocurrent (MSC) and magnetic injection photocurrent (MIC) in time-reversal symmetry and inversion symmetry broken system. We show that MSC is mainly governed by shift vector and interband Berry curvature, and MIC is dominated by absorption strength and asymmetry of the group velocity difference at time-reversed $\pm$$\textbf{k}$ points. MSC and MIC can be induced by circularly and linearly polarized light, respectively, in $\mathcal{PT}$-symmetric systems with $\mathcal{P}$ and $\mathcal{T}$ being individually broken. Taking $\mathcal{PT}$-symmetric magnetic topological quantum material bilayer antiferromagnetic (AFM) MnBi$_2$Te$_4$ as an example, we predict the presence of large MIC in the terahertz frequency regime which can be magnetically switched between two AFM states with time-reversed spin orderings. While NSC vanishes in $\mathcal{T}$-symmetric systems, external electric field breaks $\mathcal{PT}$ symmetry and enables large NSC response which can be electrically switched. MIC and NSC are perpendicular to each other upon linearly $x$/$y$-polarized light, and are highly tunable under electric field, resulting in giant nonlinear photocurrent response down to a few THz regime. It suggests bilayer AFM MnBi$_2$Te$_4$ as a tunable platform with rich THz and magneto-optoelectronic applications. The present work reveals that nonlinear photocurrent provides a powerful tool for deciphering magnetic structures and interactions, particularly fruitful for probing and understanding magnetic topological quantum materials.

description: A description and analysis of China's Farmer Specialized Cooperatives is presented. Data is presented regarding the historical development of farmer cooperatives in China, the membership composition of a sample of 66 farmer cooperatives in the Zhejiang province, and the various attributes (governance, quality control system, and strategy) of a watermelon cooperative in this province. Many cooperatives are being transformed in organizations with a market orientation. These cooperatives exhibit substantial heterogeneity, in terms of farmers being member and skewness in the distribution of control rights. Human asset specificity in terms of establishing and maintaining relations and access to markets seems to be more important than physical asset specificity in accounting for governance structure choice in the current institutional setting.
