Subjects: Productivity Analysis

description: The relationship between the degree of competitive market pressure and the rate of productivity growth is empirically investigated with a case study of the Florida fresh winter vegetable industry. The results indicate that crops which faced considerable competitive pressure exhibited significant productivity growth while the crops that faced minimal competitive pressure generally exhibited little growth in productivity. Thus, the hypothesis that competitive pressure is positively related to productivity growth is supported.

description: A vector autoregression (VAR) model of corn, farm egg, and retail egg prices is estimated and shocked with a corn price increase. Impulse responses in egg prices, t-statistics for the impulse responses, and decompositions of forecast error variance are presented. Analyses of results provide insights on the corn/egg price transmission mechanism and on how corn price shocks pulsate through the egg-related economy.

description: This paper develops Engel relationships to identify the determinants of household expenditures on nursery products and specifies their impact on consumer purchases of these goods for subregions of the United States. Household income, the number of single family home construction starts, educational level attained, and age composition of the population were found in influence nursery product expenditures. The economic variables of income and construction starts appear to be key factors affecting nursery purchases. To maintain a competitive edge, industry participants should monitor these variables carefully and adjust their production and marketing plans to meet changing market conditions.

Publisher: name: Unknown
Year: 1990
Subjects: Food Consumption/Nutrition/Food Safety

description: To analyze fresh vegetable consumption using household survey data, the tobit model and a more flexible parameterization to the tobit model - the "double hurdle" model - were considered. Based on the likelihood ratio test, the tobit model was rejected against the "double hurdle" specification. Moreover, the results suggest that the tobit model underestimated the impact of the explanatory variables on fresh vegetable expenditures. Other results indicate that total food expenditures (proxy for income), age, household composition, sex, race, marital status, urbanization, region, and seasonality are all important determinants of fresh vegetable expenditures.

Demand and Price Analysis

description: Because so much agricultural policy analysis utilizes estimates of supply and demand elasticities, it is crucial to obtain the most reliable estimates possible. Where reliability cannot be adequately assessed, the sensitivity of elasticities to equally plausible a priori specifications should at least be ascertained. In this article, the sensitivity of U.S. output supply and input demand elasticities to choice of functional form. Considerable sensitivity is found to choice of functional form. Although most frequently used, the translog is generally the outlier and is the least preferred among the alternatives.

description: Conjoint analysis was used to estimate individual preference functions for food safety attributes. Consumer segments were constructed by using cluster analysis to form groups which were homogeneous with respect to preferences regarding food safety. Although substantial differences existed among the three distinct groups, consumers in all segments were willing to pay a moderate amount to ensure that apples met established safety standards. However, a policy which restricts pesticide use would likely result in substantial consumer dissatisfaction, unless it could be achieved with little impact on price or quality.

description: This article analyzes the dynamics effects of the farm subsidies in the United States. The subsidies a farmer receives are based upon historical plantings, also called based acreage. It is sometimes optimal for a farmer temporarily not to participate in a program in order to increase future subsidies. The farmer's optimal policy is the solution to a deterministic dynamic program. Farmers with low base acreage opt out of these programs, whereas those with high base acreage participate in them. The article examines aggregate data involving corn, cotton, rice, and wheat during 1987. It shows that these programs increase the output of each of these crops and represent an annual deadweight loss of more than $2 billion.

description: The angular dependence of the tensor Ayy and vector Ay analyzing powers in the inelastic scattering of deuterons with a momentum of 9.0 GeV/c on hydrogen and carbon have been measured. The range of measurements corresponds to the baryonic resonance excitation with masses 2.2--2.6 GeV/c^2. The Ayy data being in good agreement with the previous results demonstrate an approximate $t$ scaling up to -1.5 (GeV/c)^2. The large values of A_y show a significant role of the spin-dependent part of the elementary amplitude of the NN->NN* reaction. The results of the experiment are compared with model predictions of the plane-wave impulse approximation.

description: The principles of minimal sensitivity (PMS) criterion is applied to the perturbative free energy density, or pressure, of hot QCD, which include the $\sim g_s^6 \ln g_s$ and part of the $\sim g_s^6$ terms. Applications are made separately to the short- and long-distance parts of the pressure. Comparison with the lattice results, at low temperatures, shows that the resultant `` optimal'' approximants are substantially improved when compared to the $\bar{MS}$ results. In particular, for the realistic case of three quark flavors, the `` optimal'' approximants are comparable with the lattice results.

On the Meaning and Inapplicability of the Zeldovich Relations of Magnetohydrodynamics

description: Considering a plasma with an initially weak large scale field subject to nonhelical turbulent stirring, Zeldovich (1957), for two-dimensions, followed by others for three dimensions, and Zeldovich et al. (1983) have presented formulae of the form $=f(R_M){Bbar}^2$. Such ``Zeldovich relations'' have sometimes been interpreted to provide steady-state relations between the energy associated with the fluctuating magnetic field and that associated with a large scale or mean field multiplied by a function $f$ that depends on spatial dimension and a magnetic Reynolds number $R_M$. Here we dissect the origin of these relations and pinpoint pitfalls that show why they are inapplicable to realistic, dynamical MHD turbulence and that they disagree with many numerical simulations. For 2-D, we show that when the total magnetic field is determined by a vector potential, the standard Zeldovich relation applies only transiently, characterizing a maximum possible value that the field energy can reach before necessarily decaying. in relation to a seed value $Bbar$. In 3-D, we show that the standard Zeldovich relations are derived by balancing subdominant terms. In contrast, balancing the dominant terms shows that the fluctuating field can grow to a value independent of $R_M$ and the initially imposed $Bbar$, as seen in numerical simulations. We also emphasize that these Zeldovich relations of nonhelical turbulence imply nothing about the amount mean field growth in a helical dynamo. In short, by re-analyzing the origin of the Zeldovich relations, we highlight that they are inapplicable to realistic steady-states of large $R_M$ MHD turbulence.

description: We present a comprehensive study of the chiral-index assignment of carbon nanotubes in aqueous suspensions by resonant Raman scattering of the radial breathing mode. We determine the energies of the first optical transition in metallic tubes and of the second optical transition in semiconducting tubes for more than 50 chiral indices. The assignment is unique and does not depend on empirical parameters. The systematics of the so-called branches in the Kataura plot are discussed; many properties of the tubes are similar for members of the same branch. We show how the radial breathing modes observed in a single Raman spectrum can be easily assigned based on these systematics. In addition, empirical fits provide the energies and radial breathing modes for all metallic and semiconducting nanotubes with diameters between 0.6 and 1.5 nm. We discuss the relation between the frequency of the radial breathing mode and tube diameter. Finally, from the Raman intensities we obtain information on the electron-phonon coupling.

description: The meson decays $B\to Dτν$ and $B\to D^* τν$ are sensitive probes of the $b\to cτν$ transition. In this work we present a complete framework to obtain the maximum information on the physics of $B\to D^{(*)}τν$ with polarized $τ$ leptons and unpolarized $D^{(*)}$ mesons. Focusing on the hadronic decays $τ\to πν$ and $τ\toρν$, we show how to extract seven $τ$ asymmetries from a fully differential analysis of the final-state kinematics. At Belle II with $50~\text{ab}^{-1}$ of data, these asymmetries could potentially be measured with percent level statistical uncertainty. This would open a new window into possible new physics contributions in $b\to cτν$ and would allow us to decipher its Lorentz and gauge structure.

description: We show through rigorous calculations that dielectric microspheres can be organized by an incident electromagnetic plane wave into stable cluster configurations, which we call photonic molecules. The long-range optical binding force arises from multiple scattering between the spheres. A photonic molecule can exhibit a multiplicity of distinct geometries, including quasicrystal-like configurations, with exotic dynamics. Linear stability analysis and dynamical simulations show that the equilibrium configurations can correspond with either stable or a type of quasi-stable states exhibiting periodic particle motion in the presence of frictional dissipation.

description: Tracking and locating radio-tagged wildlife is a labor-intensive and time-consuming task necessary in wildlife conservation. In this article, we focus on the problem of achieving embedded autonomy for a resource-limited aerial robot for the task capable of avoiding undesirable disturbances to wildlife. We employ a lightweight sensor system capable of simultaneous (noisy) measurements of radio signal strength information from multiple tags for estimating object locations. We formulate a new lightweight task-based trajectory planning method-LAVAPilot-with a greedy evaluation strategy and a void functional formulation to achieve situational awareness to maintain a safe distance from objects of interest. Conceptually, we embed our intuition of moving closer to reduce the uncertainty of measurements into LAVAPilot instead of employing a computationally intensive information gain based planning strategy. We employ LAVAPilot and the sensor to build a lightweight aerial robot platform with fully embedded autonomy for jointly tracking and planning to track and locate multiple VHF radio collar tags used by conservation biologists. Using extensive Monte Carlo simulation-based experiments, implementations on a single board compute module, and field experiments using an aerial robot platform with multiple VHF radio collar tags, we evaluate our joint planning and tracking algorithms. Further, we compare our method with other information-based planning methods with and without situational awareness to demonstrate the effectiveness of our robot executing LAVAPilot. Our experiments demonstrate that LAVAPilot significantly reduces (by 98.5%) the computational cost of planning to enable real-time planning decisions whilst achieving similar localization accuracy of objects compared to information gain based planning methods, albeit taking a slightly longer time to complete a mission.

Probing anisotropies of gravitational-wave backgroundswith a space-based interferometer II: Perturbative reconstruction of a low-frequency skymap

description: We present a perturbative reconstruction method to make a skymap of gravitational-wave backgrounds (GWBs) observed via space-based interferometer. In the presence of anisotropies in GWBs, the cross-correlated signals of observed GWBs are inherently time-dependent due to the non-stationarity of the gravitational-wave detector. Since the cross-correlated signal is obtained through an all-sky integral of primary signals convolving with the antenna pattern function of gravitational-wave detectors, the non-stationarity of cross-correlated signals, together with full knowledge of antenna pattern functions, can be used to reconstruct an intensity map of the GWBs. Here, we give two simple methods to reconstruct a skymap of GWBs based on the perturbative expansion in low-frequency regime. The first one is based on harmonic-Fourier representation of data streams and the second is based on "direct" time-series data. The latter method enables us to create a skymap in a direct manner. The reconstruction technique is demonstrated in the case of the Galactic gravitational wave background observed via planned space interferometer, LISA. Although the angular resolution of low-frequency skymap is rather restricted, the methodology presented here would be helpful in discriminating the GWBs of galactic origins by those of the extragalactic and/or cosmological origins.

Geochemistry of selenium release from the Elk River Valley coal mines
Creators: name: Lussier, Christine
Publisher: name: University of British Columbia
Year: 2009

description: Elevated levels of selenium (Se) were detected downstream from the five open pit coal mines in the Elk River Valley, British Columbia. Se is an essential nutrient but, in excessive amounts, it may cause teratogenic deformities and reproductive failure in fish and birds. To provide mine operators in the Elk River Valley with the information needed to assess the risk of Se release from waste rock and plant refuse a study of Se's modes of occurrence in the strata disturbed by mining and the geochemical mechanisms of its release was conducted. The mineralogical associations of Se were studied in 16 samples representative of the different types of material at the sites. Methods used to characterize sample mineralogy include X-ray diffraction, scanning electron microscopy, sequential extractions and heavy liquid separation. Se had both organic and inorganic associations in all lithologies tested, but sulphides, in particular pyrite, were indicated as the main Se-bearing component in the studied lithologies. The amount of organic matter in the materials appeared to play a role in determining the degree of Se enrichment in sulphides, with materials high in organics containing sulphides with less Se substitution. Humidity cells were used to determine the rate of Se release from coal, interburden, foot wall, parting and coarse refuse. The rate of Se release was not proportional to the total amount of Se in the sample, suggesting that mineralogical factors, such as texture, pyrite liberation and porosity, determine the rate of Se oxidation. A strong positive correlation between the amount of Se and sulphate in leachate from the humidity cells, suggested that sulphide oxidation is likely the source of Se being released into tributaries of the Elk River.
Tricritical directed percolation in 2+1 dimensions

Year: 2005
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We present detailed simulations of a generalization of the Domany-Kinzel model to 2+1 dimensions. It has two control parameters $p$ and $q$ which describe the probabilities $P_k$ of a site to be wetted, if exactly $k$ of its "upstream" neighbours are already wetted. If $P_k$ depends only weakly on $k$, the active/adsorbed phase transition is in the directed percolation (DP) universality class. If, however, $P_k$ increases fast with $k$ so that the formation of inactive holes surrounded by active sites is suppressed, the transition is first order. These two transition lines meet at a tricritical point. This point should be in the same universality class as a tricritical transition in the contact process studied recently by Lübeck. Critical exponents for it have been calculated previously by means of the field theoretic epsilon-expansion ($ε= 3-d$, with $d=2$ in the present case). Rather poor agreement is found with either.

description: This article reviews various models that may be used to explain optimal leverage choice for the proprietary farmer in a stochastic dynamic environment and develops a new model that highlights the risk of failure rather than the usual concept of risk as the variability of wealth.

description: Electromagnetic energy loss of tau leptons is an important ingredient for eventual tau neutrino detection from high energy astrophysical sources. Proposals have been made to use mountains as neutrino converters, in which the emerging tau decays in an air shower. We use a stochastic evaluation of both tau neutrino conversion to taus and of tau electromagnetic energy loss. We examine the effects of the propagation for mono-energetic incident tau neutrinos as well as for several neutrino power-law spectra. Our main result is a parameterization of the tau electromagnetic energy loss parameter beta. We compare our analytic expression for the tau flux using this beta with other parameterizations of beta.

description: We present a complete analysis of the Nernst signal due to superconducting fluctuations in a large variety of superconductors from conventional to unconventional ones. A closed analytical expression of the fluctuation contribution to the Nernst signal is obtained in a large range of temperature and magnetic field. We apply this expression directly to experimental measurements of the Nernst signal in Nb$_x$Si$_{1-x}$ thin films and a URu$_2$Si$_2$ superconductors. Both magnetic field and temperature dependence of the available data are fitted with very good accuracy using only two fitting parameters, the superconducting temperature $T_{\mathrm{c0}}$ and the upper critical field $H_{\mathrm{c2}}$. The obtained values agree very well with experimentally obtained values. We also extract the ghost lines (maximum of the Nernst signal for constant temperature or magnetic field) from the complete expression and also compare it to several experimentally obtained curves. Our approach predicts a linear temperature dependence for the ghost critical field well above $T_{\mathrm{c0}}$. Within the errors of the experimental data, this linearity is indeed observed in many superconductors far from $T_{\mathrm{c0}}$.

description: The popularity of media sharing platforms in recent decades has provided an abundance of open source data that remains underutilized by heritage scholars. By pairing geotagged internet photographs with machine learning and computer vision algorithms, we build upon the current theoretical discourse of anthropology associated with visuality and heritage tourism to identify travel patterns across a known archaeological heritage circuit, and quantify visual culture and experiences in Cuzco, Peru. Leveraging large-scale in-the-wild tourist photos, our goals are to (1) understand how the intensification of tourism intersects with heritage regulations and social media, aiding in the articulation of travel patterns across Cuzco's heritage landscape; and to (2) assess how aesthetic preferences and visuality become entangled with the rapidly evolving expectations of tourists, whose travel narratives are curated on social media and grounded in historic site representations.

description: A split-valuation method is developed and implemented to elicit the willingness to pay to consume- or avoid consuming- a product of ambiguous quality. The split-valuation method uses experimental auction markets to separate and value the positive and negative attributes of the ambiguous good. The results show that the method can be used to successfully value a good ambiguous quality. Our application reveals that for a sample of students at a midwestern land-grant institution, the average respondent is willing to pay a premium for meat produced with the use of a genetically engineered growth enhancer that has 30% to 60% fewer calories and is 10% to 20% leaner.

description: In this work, the geometric relation between space time block code design for the coherent channel and its non-coherent counterpart is exploited to get an analogue of the information theoretic inequality $I(X;S)\le I((X,H);S)$ in terms of diversity. It provides a lower bound on the performance of non-coherent codes when used in coherent scenarios. This leads in turn to a code design decomposition result splitting coherent code design into two complexity reduced sub tasks. Moreover a geometrical criterion for high performance space time code design is derived.

description: Spherical accretion flows are simple enough for analytical study, by solution of the corresponding fluid dynamic equations. The solutions of stationary spherical flow are due to Bondi. The questions of the choice of a physical solution and of stability have been widely discussed. The answer to these questions is very dependent on the problem of boundary conditions, which vary according to whether the accretor is a compact object or a black hole. We introduce a particular, simple form of stationary spherical flow, namely, self-similar Bondi flow, as a case with physical interest in which analytic solutions for perturbations can be found. With suitable no matter-flux-perturbation boundary conditions, we will show that acoustic modes are stable in time and have no spatial instability at r=0. Furthermore, their evolution eventually becomes ergodic-like and shows no trace of instability or of acquiring any remarkable pattern.

description: A nationwide retail survey is used to estimate hedonic prices of fat characteristics in beef table cuts. Results show that consumers consistently place a negative value on external fat for all table cuts and on seam fat in chuck and round cuts, but do not consistently value intramuscular fat. These consumer preferences are not transmitted to cattle feeders through price signals, even though the current beef grading system can distinguish carcasses with undesirable fat characteristics.

description: The complementary fusion of light detection and ranging (LiDAR) data and image data is a promising but challenging task for generating high-precision and high-density point clouds. This study proposes an innovative LiDAR-guided stereo matching approach called LiDAR-guided stereo matching (LGSM), which considers the spatial consistency represented by continuous disparity or depth changes in the homogeneous region of an image. The LGSM first detects the homogeneous pixels of each LiDAR projection point based on their color or intensity similarity. Next, we propose a riverbed enhancement function to optimize the cost volume of the LiDAR projection points and their homogeneous pixels to improve the matching robustness. Our formulation expands the constraint scopes of sparse LiDAR projection points with the guidance of image information to optimize the cost volume of pixels as much as possible. We applied LGSM to semi-global matching and AD-Census on both simulated and real datasets. When the percentage of LiDAR points in the simulated datasets was 0.16%, the matching accuracy of our method achieved a subpixel level, while that of the original stereo matching algorithm was 3.4 pixels. The experimental results show that LGSM is suitable for indoor, street, aerial, and satellite image datasets and provides good transferability across semi-global matching and AD-Census. Furthermore, the qualitative and quantitative evaluations demonstrate that LGSM is superior to two state-of-the-art optimizing cost volume methods, especially in reducing mismatches in difficult matching areas and refining the boundaries of objects.

description: The dynamics of opinion formation in large groups of people is a complex non-linear phenomenon whose investigation is just at the beginning. Both collective behaviour and personal view play an important role in this mechanism. In the present work we mimic the dynamics of opinion formation of a group of agents, represented by two state $\pm 1$, as a stochastic response of each of them to the opinion of his/her neighbours in the social network and to feedback from the average opinion of the whole. In the light of recent studies, a scale-free Barabási-Albert network has been selected to simulate the topology of the interactions. A turbulent-like dynamics, characterized by an intermittent behaviour, is observed for a certain range of the model parameters. The problem of uncertainty in decision taking is also addressed both from a topological point of view, using random and targeted removal of agents from the network, and by implementing a three state model, where the third state, zero, is related to the information available to each agent. Finally, the results of the model are tested against the best known network of social interactions: the stock market. A time series of daily closures of the Dow Jones index has been used as an indicator of the possible applicability of our model in the financial context. Good qualitative agreement is found.

description: The objectives of this study were to: (a) quantify differences in liquidity costs between Kansas City and Chicago wheat futures contracts, and (b) identify the factors which influence liquidity in these two markets. Regression results suggest that there are significant differences in liquidity costs between Chicago and Kansas City which are in part due to the lower trading volume at Kansas City. However, there appears to be a significantly higher cost of doing business at Kansas City which is independent of trading volume. The implications of these findings to traders is that transacting is more expensive in Kansas City than in Chicago.

description: In the spirit of Leamer's commitment to sensitivity analysis, we employ Farrell's nonparametric efficiency methodology and compare our results with those of Sexton, Wilson, and Wann. Testing the implicit assumption of technical efficiency in the methodology employed by Sexton, Wilson, and Wann, we find that the lack of technical efficiency is the cotton gins' main cause of overall inefficiency. We extend the nonparametric methodology by subjecting the shadow prices of technical efficiency to nonparametric statistical tests to draw stronger conclusions. In addition, the nonparametric methodology permits us to make gin-specific recommendations to improve the performance of the gins.

description: This paper contains sharp estimates about the distribution of multiple random integrals of functions of several variables with respect to a normalized empirical measure, about the distribution of U-statistics and multiple Wiener-Ito integrals with respect to a white noise. It also contains good estimates about the supremum of appropriate classes of such integrals or U-statistics. The proof of most results is omitted, I have concentrated on the explanation of their content and the picture behind them. I also tried to explain the reason for the investigation of such questions. My goal was to yield such a presentation of the results which a non-expert also can understand, and not only on a formal level.

description: We demonstrate phase lock of two >1.6W Titanium:sapphire lasers with a phase noise of -138dBc/Hz at 1MHz from the carrier, using an intra-cavity electro-optic phase modulator. The residual phase variance is 2.5 10^(-8)rad^2 integrated from 1Hz to 10kHz. Instantaneous offset frequency steps of up to 4MHz are achieved within 200ns. Simultaneous atom interferometers can make full use of this ultra-low phase noise in differential measurements by suppressing common influences from vibration of optics.

description: The Lie algebra of the group SU(2) is constructed from two deformed oscillator algebras for which the deformation parameter is a root of unity. This leads to an unusual quantization scheme, the {J2,Ur} scheme, an alternative to the familiar {J2,Jz} quantization scheme corresponding to common eigenvectors of the Casimir operator J2 and the Cartan operator Jz. A connection is established between the eigenvectors of the complete set of commuting operators {J2,Ur} and mutually unbiased bases in spaces of constant angular momentum.

Resistance des abattoirs locaux en zone de montagne et filieres de qualite

description: In Switzerland, the number of abattoirs has dramatically decreased in the last ten years (-24,2 %). This is especially true for small structures (- 25,7 %). The modifications of the legislation after the various meat scandals are partially responsible for this decrease. As a matter of fact, the measures with regard to ensure a high quality in meat and to reassure consumers lead to investments that can only be met with difficulty by small abattoirs. In mountainous areas we observe that the required renovation of small abattoirs and, in certain cases, even new premises are financed by the communities. The reason for this support is an effort to keep agriculture in those regions. In interviews with professionals of the meat sector, three factors for this extraordinary support for abattoirs were highlighted. First, a local abattoir provides the meat producers with nearby slaughtering facilities for urgent slaughtering, and the transporting of the animals can be kept short. Second, consumer-proximity and directed ways of distribution and sale is assured. Finally, there is a will to maintain small local abattoirs to develop and improve the supply chains of quality products. Preserving small local abattoirs is essential for their impact in terms of agricultural dynamism in mountainous areas, of value creation, and of externalities. A comprehensive understanding of these different interacting mechanisms should allow the state and the professionals of the meat sector to find common solutions.
