description: The introduction of measurement bias in parameter estimates into non-linear discrete choice models, as a result of using factor analysis, was identified by Train et al. (1987). They found that the inclusion of factor scores, used to represent relationships amongst like variables, into a subsequent discrete choice models introduced measurement bias as the measurement error associated with each factor score is excluded. This is an issue for non-market valuation given the increase in popularity of including psychometric data, such as primitive beliefs, attitudes and motivations, in willingness to pay estimates. This study explores the relationship between willingness to pay and primitive beliefs through a case study eliciting Perth community values for drinking recycled wastewater. The standard discrete decision model, with sequential inclusion of factor scores, is compared to an equivalent discrete decision model, which corrects for the measurement bias by simultaneously estimating the underlying latent variables using a measurement model. Previous research has focused on the issue of biased parameters. Here we also consider the implications for willingness to pay estimates.

description: Andrew Fearne, Professor of Food Marketing and Supply Chain Management and a Director of the dunnhumby Academy of Consumer Research at Kent University, UK, is a current Thinker in the Adelaide Thinkers in Residence (ATIR) program. Professor Fearne is the 14th person to undertake a Thinkers appointment. The residency theme, Food and Wine Value Chains: Prosperity through Collaboration, has provided a timely opportunity for partners, including wine companies, government agencies, universities, an industry association and a regional development board to review micro and macro strategies and policies from a value chain perspective. The residency was initiated to improve sustainable competitive advantage within South Australian food and wine value chains. Its timing has coincided with, and aligns with, community concern and national policy issues in grocery pricing, water policy, drought/climate change, health-wellbeing agendas, waste and food security; all converging and impacting on food and wine supply chains. The paper provides background about the Adelaide Thinkers in Residence program and partner objectives for the residency: it refers to other chain research involving Professor Fearne at dunnhumby and in Tasmania, where better insight to consumer behaviour is the basis for product and process adjustment, with the possibility of better outcomes for consumers and stakeholders; it outlines a major wine value chain analysis project in SA and identifies some main themes to emerge from this Thinker’s program. Professor Fearne will be reporting to the South Australian Government during 2009.

description: Starting from an exact relationship between news, threshold and price return distributions in the stationary state, I discuss the ability of the Ghoulmie-Cont-Nadal model of traders to produce fat-tailed price returns. Under normal conditions, this model is not able to transform Gaussian news into fat-tailed price returns. When the variance of the news so small that only the players with zero threshold can possibly react to news, this model produces Levy-distributed price returns with a -1 exponent. In the special case of super-linear price impact functions, fat-tailed returns are obtained from well-behaved news.

description: Two-photon and two-gluon annihilation rates of $η_c$, $η'_c$, $η_b$ and $η'_b$ are estimated in the relativistic Salpeter method. By solving the full Salpeter equation with a well defined relativistic wave function, we estimate $M_{η_c}=2.979\pm 0.432$ GeV, $M_{η'_c}=3.566\pm 0.437$ GeV, $M_{η_b}=9.364\pm 1.120$ GeV and $M_{η'_b}=9.941\pm 1.112$ GeV. We calculated the transition amplitude using the Mandelstam formalism and estimate the decay widths: $Γ(η_c \to 2γ)=7.14\pm 0.95$ KeV, $Γ(η'_c \to 2γ)=4.44\pm 0.48$ KeV, $Γ(η_b \to 2γ)=0.384\pm 0.047$ KeV and $Γ(η'_b \to 2γ)=0.191\pm 0.025$ KeV. We also give estimates of total widths by the two-gluon decay rates: $Γ_{tot}(η_c)=19.6\pm 2.6$ MeV, $Γ_{tot}(η'_c)=12.1\pm 1.3$ MeV, $Γ_{tot}(η_b)=6.98\pm 0.85$ MeV and $Γ_{tot}(η_b)=3.47\pm 0.45$ MeV.

description: This paper aims to clarify certain aspects of the connections between music and (word) language alluded to in various manuscript passages by Wittgenstein. Three points are emphasized: (1) Wittgenstein’s willingness to speak of music as a language; (2) the importance of context; (3) the possibility of distinguishing various ways of explaining our hearing certain sequences of sounds as expressive of gestures or states of mind etc. Several attempts at elucidating the idea of understanding music lead to the realization that, according to Wittgenstein, a prior grasp of his notion of a language-game is required to make headway in this area.

Demand and Price Analysis

description: The typical model of retail pricing for produce products assumes retailers set price equal to the farm price plus a certain markup. However, observations from scanner data indicate a large degree of price dispersion in the grocery retailing market. In addition to markup pricing behavior, we document three alternative leading pricing patterns: fixed (constant) pricing, periodic sale, and high-low pricing. Retail price variations under these alternative pricing regimes in general have little correlation with the farm price. How do retailers’ alternative pricing behaviors affect farmers’ welfare? Using markup pricing as the baseline case, we parameterize the model to reflect a prototypical fresh produce market and carry out a series of simulations under different pricing regimes. Our study shows that if harvest cost is sufficiently low, retail prices adjusting only partially, or not at all, to supply shocks tends to diminish farm income and exacerbate farm price volatility relative to the baseline case. However, we also find that if harvest cost is sufficiently large and the harvest-cost constraint places a lower bound on the farm price, increased farm price volatility induced by retailers’ alternative pricing strategies may result in higher farm income, compared to markup pricing. Our study is the first to evaluate the welfare implications for producers of the diversified pricing strategies that retailers utilize in practice and the resulting attenuation of the relationship between prices at retail and at the farm gate.

description: In the study of perturbations around black hole configurations, whether an external source can influence the perturbation behavior is an interesting topic to investigate. When the source acts as an initial pulse, it is intuitively acceptable that the existing quasinormal frequencies will remain unchanged. However, the confirmation of such an intuition is not trivial for the rotating black hole, since the eigenvalues in the radial and angular parts of the master equations are coupled. We show that for the rotating black holes, a moderate source term in the master equation in the Laplace s-domain does not modify the quasinormal modes. Furthermore, we generalize our discussions to the case where the external source serves as a driving force. Different from an initial pulse, an external source may further drive the system to experience new perturbation modes. To be specific, novel dissipative singularities might be brought into existence and enrich the pole structure. This is a physically relevant scenario, due to its possible implication in modified gravity. Our arguments are based on exploring the pole structure of the solution in the Laplace s-domain with the presence of the external source. The analytical analyses are verified numerically by solving the inhomogeneous differential equation and extracting the dominant complex frequencies by employing the Prony method.

description: If today a decidedly analytical interpretation of Wittgenstein’s thought seems to be dominant in many ways, there are, in my opinion, countless reasons that lead instead to reintroduce the possibility, and even the opportunity, of a different reading: a proper philosophical-aesthetic reading – where “philosophical” is equivalent to “transcendental” in the Kantian sense – which certainly seems to me more productive in theoretical terms.

Taylor-Couette instability of a Bingham fluid
Creators: name: Landry, Maria Paulina
Publisher: name: University of British Columbia
Year: 2009

description: Stability of a Bingham fluid in Taylor-Couette flow is studied. Of interest is to determine the critical values of the inner and outer cylinder angular velocities which cause the linear instability in the system. We introduce a perturbation into the basic flow, and examine the linearized Navier-Stokes equations for the perturbation. Assuming a normal mode solution for the perturbation, we obtain an eigenvalue problem which determines when the perturbation will grow or decay with time. In the case of a plug region at the outer cylinder wall, additional boundary conditions are applied at the yield surface. The marginal stability curve is generated numerically using a finite difference method. In addition to numerical analysis, heuristic arguments and energy methods are applied to find a lower bound for stability.

description: Exploding data volumes and velocities, new computational methods and platforms, and ubiquitous connectivity demand new approaches to computation in the sciences. These new approaches must enable computation to be mobile, so that, for example, it can occur near data, be triggered by events (e.g., arrival of new data), be offloaded to specialized accelerators, or run remotely where resources are available. They also require new design approaches in which monolithic applications can be decomposed into smaller components, that may in turn be executed separately and on the most suitable resources. To address these needs we present funcX---a distributed function as a service (FaaS) platform that enables flexible, scalable, and high performance remote function execution. funcX's endpoint software can transform existing clouds, clusters, and supercomputers into function serving systems, while funcX's cloud-hosted service provides transparent, secure, and reliable function execution across a federated ecosystem of endpoints. We motivate the need for funcX with several scientific case studies, present our prototype design and implementation, show optimizations that deliver throughput in excess of 1 million functions per second, and demonstrate, via experiments on two supercomputers, that funcX can scale to more than more than 130000 concurrent workers.

description: The effect of subsidies on farm production has been a major topic in agricultural economics for several decades. We present a new approach for analyzing the effects of different types of coupled and decoupled subsidies on farm production with econometric methods. In contrast to most previous studies, our approach is entirely based on a theoretical microeconomic model, explicitly allows subsidies to have an impact on input use, and takes linkages between the farm and the farm household into account.

description: X-ray spectroscopy has been a key method to determine ground and excited state properties of quantum materials with atomic specificity. Now, new x-ray facilities are opening the door to the study of pump-probe x-ray spectroscopy - specifically time-resolved x-ray absorption (trXAS) and time-resolved resonant inelastic x-ray scattering (trRIXS). In this paper we will present simulations of each of these spectroscopies using a time-domain full atomic multiplet, charge transfer Hamiltonian, adapted to study the properties of a generalized cluster model including a central transition metal ion caged by ligand atoms in a planar geometry. The numerically evaluated trXAS and trRIXS cross-sections for representative electron configurations $3d^9$ and $3d^8$ demonstrate the insights that can be obtained from charge transfer pumping, and how this nonequilibrium process affects ground and excited state properties. The straightforward characterization of the excitations in these systems, based on our analysis of the simulations, can serve as a benchmark for future experiments, as access to these time-resolved spectroscopic techniques becomes more widely available.

description: The compound $Nb_{5-δ}Te_4$ ($δ=0.23$) with quasi-one-dimensional crystal structure undergoes a transition to superconductivity at $T_c$=0.6--0.9 K. Its electronic transport properties in the normal state are studied in the temperature range 1.3--270 K and in magnetic fields up to 11 T. The temperature variation of the resistivity is weak ($<2%$) in the investigated temperature range. Nonmonotonic behavior of the resistivity is observed which is characterized by two local maxima at $T\sim$2 K and $\sim$30 K. The temperature dependence of the resistivity is interpreted as an interplay of weak localization, weak antilocalization, and electron-electron interaction effects in the diffusion and the Cooper channel. The temperature dependence of the dephasing time $τ_ϕ$ extracted from the magnetoresistance data is determined by the electron-phonon interaction. The saturation of $τ_ϕ$ in the low-temperature limit correlates with $T_c$ of the individual crystal and is ascribed to the scattering on magnetic impurities.

description: The Greenhouse Gases from Agriculture Simulation Model (GreenAgSiM) presented in this paper aims to quantify emissions from agricultural activity on a global scale. The model takes emissions into account that are directly attributable to agricultural production, such as enteric fermentation (methane), manure management (methane and nitrous oxide), and agricultural soil management (nitrous oxide). Furthermore, carbon stock differences from land-use change (carbon dioxide) induced by agriculture are included in the model. The model will provide policy makers with information about the greenhouse gas implications of policy changes.

description: In recent decades, the potential contribution of agriculture to economic growth has been a subject of much controversy among development economists. While some contend that agricultural development is a precondition to industrialization, others strongly disagree and argue for a different path. Taking advantage of recent developments in time series econometric methods, this paper re-examines the question of whether agriculture could serve as an engine of growth. Results from the empirical analysis provide strong evidence indicating that agriculture is an engine of economic growth. Furthermore, we find that trade openness has a positive effect on GDP growth.

description: This paper examines the consequences of data error in data series used to construct aggregate indicators. Using the most popular indicator of country level economic development, the Human Development Index (HDI), we identify three separate sources of data error. We propose a simple statistical framework to investigate how data error may bias rank assignments and identify two striking consequences for the HDI. First, using the cutoff values used by the United Nations to assign a country as ‘low’, ‘medium’, or ‘high’ developed, we find that currently up to 45% of developing countries are misclassified. Moreover, by replicating prior development/macroeconomic studies, we find that key estimated parameters such as Gini coefficients and speed of convergence measures vary by up to 100% due to data error.

The broad band (3-200 keV) spectrum of the source constructed from data of different observatories strongly supports the idea that the X-ray emission of Sgr B2 is Compton scattered and reprocessed radiation emitted in the past by the Sgr A* source. We conclude that 300-400 years ago Sgr A* was a low luminosity (L ~ 1.5e39 erg/s at 2-200 keV) AGN with a characteristic hard X-ray spectrum (photon index Gamma ~ 1.8). We estimate the mass and iron abundance of the Sgr B2 scattering gas at 2e6 Msun (r/10pc)^2 and 1.9 solar, respectively (where r is the radius of the cloud).

Global Synchronization of Pulse-Coupled Oscillator Networks Under Byzantine Attacks

Subjects: subject: Signal Processing (eess.SP)

description: Synchronization of pulse-coupled oscillators (PCOs) has gained significant attention recently due to their increased applications in sensor networks and wireless communications. Given the distributed and unattended nature of wireless sensor networks, it is imperative to enhance the resilience of PCO synchronization against malicious attacks. However, most existing results on attack-resilient pulse-based synchronization are obtained under assumptions of all-to-all coupling topologies or restricted initial phase distributions. In this paper, we propose a new pulse-based synchronization mechanism to improve the attack resilience of PCO synchronization that is applicable to non-all-to-all networks. Under the proposed synchronization mechanism, we prove that perfect synchronization of legitimate oscillators can be guaranteed in the presence of multiple Byzantine attackers who can emit attack pulses arbitrarily without any constraint except that practical bit rate constraint renders the number of pulses from an attacker to be finite. The new mechanism can guarantee synchronization even when the initial phases of all legitimate oscillators are arbitrarily distributed in the entire oscillation period, which is in distinct difference from most existing attack-resilient synchronization approaches (including the seminal paper from Lamport and Melliar-Smith [1]) that require a priori (almost) synchronization among legitimate oscillators. Numerical simulation results are given to confirm the theoretical results.

description: During these last years, Algeria, like some other developing countries is undergoing important institutional changes. The structural adjustment plan (1990s), and the association agreement signed with the European Union (2005) are some of political tools that guide these profound changes that have considerable impacts on the strategic behavior of local enterprises. Beyond these mutations at national level, important policy changes are observed at international level, like the recent reform of the European sugar policy that constitutes a considerable shifter on the behavior of enterprises operating in the Algerian sugar refining industry. The present research aims to measure the weight of the institutional criteria on the strategic decision of sugar refining companies in Algeria, by the application of the SWOT analysis. The ultimate purpose is to contribute to the analysis of interactions that exist between institutional changes induced by the globalization process and the strategic choices of local enterprises in an emergent economy.

description: The objective of this work is to analyse the relative importance of three groups of competitive advantage factors on firms’ results of the Spanish agro-food industry. Competitive advantage factors correspond to three aspects: agro-food firms internal sources called, in this study, Potential Resources (RP); agro-food firms relationships with other firms, which are called Specific Firms Relationships (RE); and, the market and industry characteristics plus the industrial localisation, which are included in the so called Market Structure and Industry Location (EMI). Seven hypotheses have been formulated to asses direct and indirect relationships between RP, RE, EMI and economic Results (R) specifying causality directions between explicative indicators for each competitive factor. The seven hypotheses have been combined in a hypothetical model with structural equations defining firms’ competitiveness. A sample of 294 firms has been used and 17 variables related to competitive advantages have been selected. Indicators related to Potential Resources refer to technological levels, development of new products as well as promotion and advertising activities. Agro-food firms’ relationships are taken into account introducing variables accounting for relationships with suppliers, distributors and other firms. The Market Structure and Industry are taken into account considering the concentration degree of the food distribution firms, entry of new firms into the market and product prices, among others. Results have been measured with indicators measuring investment over sales, added value and export intensity. Results indicate that Potential Resources and the Specific Firms Relationships explain better the variability of the Results with a strong relationship between those two groups of variables.

description: Wittgenstein’s distinction between saying and showing and the associated thesis, what can be shown cannot be said, were crucial to his first philosophy, persisted throughout the evolution of his whole thought and played a key role in his views on aesthetics. The objective of art is access to the mystical, forcing us to become aware of the uniqueness of our own experience and life. When art is good is a perfect expression and the work of art becomes like a tautology. An important consequence of this understanding of art is the irreducibility of the aesthetic to the scientific perspective.

description: The following contribution describes a product development case study for an isotonic organic sport drink in which the value factors of GfK Sinus Milieus have been applied. The underlying research question is, if the prescribed values are a viable tool to differentiate buyers and nonbuyers of organic food in respect to purchase intention in the case of sport beverages. The authors furthermore investigate the importance of “organic” or other product features for fitness oriented consumers. The paper draws on data from a survey in Austrian and German fitness centres with a total of 400 respondents. Purchase intention was indirectly measured with a Conjoint analysis, for the influence of values and factors on the purchase intention an analysis of variance was applied. Results illustrate, that the GfK values and attitudes factors are a viable tool to differentiate between shoppers and non-shoppers of organic food. Our study has shown that the necessary factors to differentiate purchase intentions are varying over product categories. Furthermore a use of single factors is not recommended, only a combination of them is able to differentiate consumers in respect to their purchase intention. Further research would be required to facilitate full understanding of the complex decision making process with regard to different product categories of organic food products. This research indicates that a combination of attitudes and values at the same time influence purchase intention. Furthermore values and attitudes differ among product categories and buying situation.

description: Light field (LF) cameras can record scenes from multiple perspectives, and thus introduce beneficial angular information for image super-resolution (SR). However, it is challenging to incorporate angular information due to disparities among LF images. In this paper, we propose a deformable convolution network (i.e., LF-DFnet) to handle the disparity problem for LF image SR. Specifically, we design an angular deformable alignment module (ADAM) for feature-level alignment. Based on ADAM, we further propose a collect-and-distribute approach to perform bidirectional alignment between the center-view feature and each side-view feature. Using our approach, angular information can be well incorporated and encoded into features of each view, which benefits the SR reconstruction of all LF images. Moreover, we develop a baseline-adjustable LF dataset to evaluate SR performance under different disparity variations. Experiments on both public and our self-developed datasets have demonstrated the superiority of our method. Our LF-DFnet can generate high-resolution images with more faithful details and achieve state-of-the-art reconstruction accuracy. Besides, our LF-DFnet is more robust to disparity variations, which has not been well addressed in literature.

description: Abstract A framework for reconciling data in U.S. notifications of domestic support to the World Trade Organization (WTO) with data from numerous U.S. sources is presented. The framework also allows projections of possible data in the future U.S. notifications. A country’s calculation of the value of production (VOP) for individual agricultural products and the total value of production are important for the analysis of domestic support constraints under the WTO Agreement on Agriculture and in the Doha negotiations. The framework consists of 65 linked spreadsheets, grouped into 54 data and 11 result tables. Information flows from the data tables to the result tables based on procedures deduced from the analysis of U.S. notifications. The results suggest that the U.S. total value of agricultural production for WTO notifications may increase by 65 percent between 2003 and 2018. As a result, de minimis allowances could increase to US$36 billion by 2018. The VOP of corn would average US$48 billion from 2009 to 2018, making corn the main component of the total value of U.S. agricultural production. The framework was also able to detect several anomalies in the VOP calculations in existing U.S. WTO notifications, confirming that it is a good tool for analyzing these notifications in the context of existing and possible future WTO rules.

description: To promote multifunctional activity, it is crucial to clarify how jointness is formed in connection with farm structure. This paper examines the relationship between multifunctional activity and farm structure by focusing on the educational function of dairy farming, i.e., farming experience services, in Japan. The main findings were as follows. First, from our conceptual consideration we can say that the educational function is determined by technical and institutional jointness and there is a U-shaped relationship between farm diversification and provision of farming experience services. In addition, the national program aimed at promoting this educational function was effective in enhancing this function. Second, however, from the empirical evaluation farmers only partially internalize educational externalities by treating them as supplementary services combined with processed products. Therefore, appropriate integrated management of these newly emerging educational services to become a viable market should be fully addressed in the future, especially for family farms.

Creators: name: ATLAS Collaboration
Publisher: name: HEPData
Year: 2014

description: Link to dijet_statcov.tgz file containing statistical covariance matrices
description: CERN-LHC. Double-differential dijet cross sections measured in pp collisions at the LHC with a 7 TeV centre-of-mass energy are presented as functions of dijet mass and rapidity separation of the two highest-pT jets. These measurements are obtained using data corresponding to an integrated luminosity of 4.5 fb^-1, recorded by the ATLAS detector in 2011. The data are corrected for detector effects so that cross sections are presented at the particle level. Cross sections are measured up to 5 TeV dijet mass using jets reconstructed with the anti-kt algorithm for values of the jet radius parameter of 0.4 and 0.6. UPDATE (15 JUL 2014): Tables 1-12 updated with complete breakdown of systematic uncertainties and two extra columns added corresponding to stronger or weaker assumptions on the correlations between the jet energy scale uncertainty components, link to statistical covariance matrices added, link to 10000 replicas added which can be used with replicas from other ATLAS results to derive the statistical correlations between measurements.
High brightness temperatures and circular polarisation in extra-galactic radio sources

description: Some rapidly variable extra-galactic radio sources show very high brightness temperatures T_B>10^{12}K and high degrees of circular polarisation (1%). Standard synchrotron models that assume a power-law electron distribution cannot produce such high temperatures and have much lower degrees of intrinsic circular polarisation. We examine the synchrotron and inverse Compton radiation from a monoenergetic electron distribution using standard synchrotron theory. Constraints on the source parameters are found by formulating the results as functions of the source size, Doppler boosting factor, optical depth to synchrotron self-absorption, maximum frequency of synchrotron emission, and the strength of the inverse Compton radiation. The model gives brightness temperatures T_B=10^{13}K to 10^{14}K for moderate (<10) Doppler boosting factors and intrinsic degrees of circular polarisation at the percent level. It predicts a spectrum I_ν\proptoν^{1/3} between the radio and the infra-red as well as emission in the MeV to GeV range. We find the conditions under which electrons do not cool within the source, enabling the GHz emission to emerge without absorption and the potentially catastrophic energy losses by inverse Compton scattering to be avoided. We suggest that sources such as PKS 1519 -273, PKS 0405 -385 and J 1819 +3845 can be understood within this scenario without invoking high Doppler boosting factors, coherent emission mechanisms, or the dominance of proton synchrotron radiation.

description: From the spread of pollutants in the atmosphere to the transmission of nutrients across cell membranes, anomalous diffusion processes are ubiquitous in natural systems. The ability to understand and control the mechanisms guiding such processes across various scales has important application to research in materials science, finance, medicine, and energetics. Here we present a numerical study of anomalous diffusion of light through a semi-crystalline polymer structure where transport is guided by random disorder and nonlocal interactions. The numerical technique examines diffusion properties in one-dimensional (1D) space via the spectrum of an Anderson-type Hamiltonian with a discrete fractional Laplacian operator (-Δ)^s, 01 (sub-diffusion) for most examined cases. An important finding of the present study is that transport can be enhanced at key spatial scales in the sub-diffusive case, where all states are normally expected to be localized for a (1D) disordered system.
The Lorenz number in the optimally doped and underdoped Eu-123 superconductor

description: The temperature dependences of the Hall-Lorenz numbers (Lxy) in a EuBa2Cu3Oy (Eu-123) single crystal before and after oxygen reduction are reported. The study is based on data on the normal state longitudinal and transversal transport coefficients. Namely, the temperature dependences of the electrical resistivity, Hall coefficient, longitudinal thermal conductivity, and transverse thermal conductivity are presented. The set of measurements was performed for an optimally doped sample (y = 7), then the oxygen content in the the same crystal was reduced to y = 6.65, and the measurements were repeated. For both cases Lxy's are about two times larger than the Sommerfeld's value of the Lorenz number and depend weakly on temperature in a range 300 - 160 K. Below T = 160 K the Hall-Lorenz number for the optimally doped sample slowly drops, while the value of Lxy for the oxygen reduced sample begins to rise. Such results suggest that the electronic system in the investigated compound may be considered as a metallic one with pseudo-gaps that open at the Fermi level.
