description: We investigate the nonlinear Meissner effect microscopically. Previous studies did not consider a certain type of interaction effect on the nonlinear phenomena. The scattering amplitude barely appears without being renormalized into the Fermi-liquid parameter. With this effect we can solve the outstanding issues (the quantitative problem, the temperature and angle dependences). The quantitative calculation is performed with use of the fluctuation-exchange approximation on the Hubbard model. It is also shown that the perturbation expansion on the supercurrent by the vector potential converges owing to the nonlocal effect.

description: The dissemination of information by extension agents on dairy management practices used to control mastitis and the reception and use of that information by producers are investigated. Producers are surveyed to determine current practices used. The relationship between milk yield, somatic cell count, management practices, and producer and production characteristics is estimated. Subjective probabilities are elicited from "expert," extension agents, and producers concerning the impact and cost of various management practices. Subjective marginal value products and marginal input costs are computed and compared for the respondent groups. Stochastic dominance is used to rank the relative importance of the practices as perceived by the respondents.

description: We present the results from the timing and spectral study of Mrk\,421 based mainly on the \emph{Swift} data in the X-ray energy range obtained during the time interval 2015\,December--2018\,April. The most extreme X-ray flaring activity on the long-term, daily and intraday timescales was observed during the 2-month period which started in 2017\,December when the 0.3--10\,keV flux exceeded a level of 5$\times$10$^{-9}$erg\,cm$^{-2}$s$^{-1}$, recorded only twice previously. While the TeV-band and X-ray variabilities mostly were correlated, the source often varied in a complex manner in the MeV--GeV and radio--UV energy ranges, indicating that the multifrequency emission of Mrk\,421 could not be always generated in a single zone. The longer-term flares at X-rays and $γ$-rays showed a lognormal character, possibly indicating a variability imprint of the accretion disk onto the jet. A vast majority of the 0.3--10\,keV spectra were consistent with the log-parabolic model, showing relatively low spectral curvature and correlations between the different spectral parameters, predicted in the case of the first and second-order Fermi processes. The position of the synchrotron spectral energy distribution (SED) peak showed an extreme variability on diverse timescales between the energies $E_{\rm p}$$$15\,keV, with 15\% of the spectra peaking at hard X-rays and was related to the peak height as $S_{\rm p}$$\varpropto$$E^α_{\rm p}$ with $α$$\sim$0.6, which is expected for the transition from Kraichnan-type turbulence into the \textquotedblleft hard-sphere\textquotedblright~ one. The 0.3--300\,GeV spectra showed the features of the hadronic contribution, jet-star interaction and upscatter in the Klein-Nishina regime in different time intervals.

description: The Langevin dynamics of a $d$-dimensional mean spherical model with competing interactions along $m\leq d$ directions of a hypercubic lattice is analysed. After a quench at high temperatures, the dynamical behaviour is characterized by two distinct time scales associated with stationary and aging regimes. The asymptotic expressions for the autocorrelation and response functions, in supercritical, critical, and subcritical cases, were calculated. Aging effects, which are known to be present in the ferromagnetic version of this model system, are not affected by the introduction of competing interactions.

description: An analysis of consumer preferences for seafood labeled with information about environmental production attributes is introduced into the food labeling literature. International seafood ecolabeling programs have proposed to create market-based incentives for fisheries managers to promote sustainable fisheries. We investigate differences in consumer preferences for ecolabeled seafood across the United States and Norway. Using a contingent-choice telephone survey of random households in each nation, a wide range of factors is found to influence consumers' likelihood of purchasing ecolabeled seafood. Consumer preferences differ by price premium, species, consumer group, and certifying agency. The effect of these factors often differs between the United States and Norway, suggesting heterogeneity in international reactions to seafood ecolabels.

description: The outer crust properties of cold non-accreting neutron stars are studied within the framework of the quark-meson coupling (QMC) model, which includes the effects of modifications of the quark structure inside individual nucleons when they are within a high-density nuclear medium. With a unique set of five well-constrained adjustable parameters, which have a clear physical basis, the QMC model gives predictions for the ground state observables of even-even nuclei which agree with experiment as well as traditional models. Furthermore, it gives improved theoretical values for nuclei thought to play a role in the outer crusts of neutron stars but for which experimental data is not available. Using the latest experimental data tables wherever possible but otherwise the predictions from the QMC model, we construct an equation of state for the outer crust which is then used within stellar model calculations to obtain an equilibrium sequence of crustal layers, each characterized by a particular neutron rich nuclei. Various properties of the layers are calculated for a range of neutron-star masses, and comparisons are made with alternative equations of state from the literature. This leads to the conclusion that the QMC model successfully predicts the outer crust properties and is fully comparable with the more traditional mass models, which all depend on a larger number of parameters.

description: Heterometallic molecular chromium wheels are fascinating new magnetic materials. We reexamine the available experimental susceptibility data on MCr7 wheels in terms of a simple isotropic Heisenberg Hamiltonian for M=Fe, Ni, Cu, and Zn and find in that FeCr7 needs to be described with an iron-chromium exchange that is different from all other cases. In a second step we model the behavior of the proton spin lattice relaxation rate as a function of applied magnetic field for low temperatures as it is measured in Nuclear Magnetic Resonance (NMR) experiments. It appears that CuCr7 and NiCr7 show an unexpectedly reduced relaxation rate at certain level crossings.

description: In 1996, Bt cotton became one of the first genetically engineered crops to be available commercially. This study focuses on the various sources and quality of information about Bt cotton profitability available to farmers in the Southeast and assesses the relative importance of such information in the farmers' adoption decisions. A model of the individual decision to adopt is developed to incorporate two recent theories of the role of information quality (the "effective information" hypothesis and the "popularity" hypothesis) as well as the effect of current technology depreciation. The data show some support for all three factors as determinants of adoption.

description: The "optimal cutting schedule" for alfalfa hay is described as a function of the trade-off between rising yield and falling quality of alfalfa over time and the local market prices being offered for different qualities of hay during the harvest season. Field test results quantify the yield/quality tradeoff for a California case study. A general decision rule is then derived to assist growers in making cutting decisions during a season. Finally, the optimal cutting schedule is shown to be the sum of sequential decisions for cuttings throughout the harvest season, with no schedule being best a priori.

A comparative study on the microstructure, rate-dependent compressive behavior, and ballistic performance of commercially available pressureless sintered boron carbide-titanium diboride (material Z) and hot-pressed boron carbide (material S) was conducted. Under quasi-static compression at rates of 1.4 to 1.6 x 10-4 s-1, the strength was found to be 3.07 ± 0.11 GPa for material Z and 4.72 ± 0.14 GPa for material S. At dynamic strain rates ranging from 185 to 1152 s-1, the compressive strength ranged from 3.56 to 4.07 GPa for material Z and 5.24 to 5.97 GPa for material S. Depth of penetration testing was performed using 7.62 mm AP M2 projectiles. The normalized ballistic efficiency of the two materials were found to be comparable at 932 m/s, while material S was superior to material Z at an impact velocity of 1078 m/s. Based on post-mortem SEM analysis of ballistic tile fragments, the inferior mechanical properties and ballistic performance of material Z are attributed to an uneven distribution of silicon impurities and a significant level of porosity.

description: This study explores two important issues in experimental economics: calibration and auction institution. Consumer willingness-to-pay bids for corn chips made with non-genetically modified ingredients are elicited in first- and second-price auctions. Results suggest that responses to scale-differential questions, elicited in a survey, accurately predicted consumer willingness-to-pay bids. While the second-price auction induced a greater percentage of marginal bidders to offer a positive bid compared to the first-price auction, average bid levels in the first- and second-price auctions were not statistically different from one other. In a small and unrepresentative sample, 70% of student participants were unwilling to pay to exchange a bag of chips made from genetically modified ingredients for a bag of chips made from nongenetically modified ingredients. However, 20% of respondents were willing to pay at least $0.25/oz. for the exchange.

description: An option-value model is developed to analyze the impacts of output price uncertainty, high sunk costs of adoption, and site-specific conditions on the optimal timing of adoption of two interrelated site-specific technologies, soil testing and variable rate technology (VRT). The model incorporates the potential for adopting these two technologies jointly or sequentially. The implications of the pattern of adoption for nitrogen pollution and for the design of a cost-share subsidy policy to accelerate the adoption of these technologies to reduce nitrogen pollution are also analyzed. Ignoring the potential for sequential adoption would tend to underpredict the adoption so soil testing and overpredict the adoption of VRT. Cost-share subsidies to induce accelerated adoption of VRT would be most effective at reducing nitrogen pollution if targeted toward fields with relatively high spatial variability in soil quality or soil fertility, and either low average soil quality or low average soil fertility.

description: We introduce a new heterotic Standard Model which has precisely the spectrum of the Minimal Supersymmetric Standard Model (MSSM), with no exotic matter. The observable sector has gauge group SU(3) x SU(2) x U(1). Our model is obtained from a compactification of heterotic strings on a Calabi-Yau threefold with Z_2 fundamental group, coupled with an invariant SU(5) bundle. Depending on the region of moduli space in which the model lies, we obtain a spectrum consisting of the three generations of the Standard Model, augmented by 0, 1 or 2 Higgs doublet conjugate pairs. In particular, we get the first compactification involving a heterotic string vacuum (i.e. a {\it stable} bundle) yielding precisely the MSSM with a single pair of Higgs.

description: With the rise of neutrino astronomy using large-volume detector arrays, calibration improvements of optical media and photosensors have emerged as significant means to reduce detector systematics. To improve understanding of the detector volume and its instrumentation, we developed an absolutely-calibrated, self-monitoring, isotropic, nanosecond, high-intensity calibration light source called "Precision Optical Calibration Module" (POCAM). This now third iteration of the instrument was developed for an application in the IceCube Upgrade but, with a modular instrument communications and synchronization backend, can provide a calibration light source standard for any large-volume photodetector array. This work summarizes the functional principle of the POCAM and all related device characteristics as well as its precision calibration procedure. The latter provides fingerprint-characterized instruments with knowledge on absolute and relative behavior of the emitted light pulses as well as their temperature dependencies.

description: This study explores the growth in demand for fast food. A distinguishing characteristic of fast food is its convenience; in today's pervasive marketplace, consumers need not travel far to find a fast food outlet. This greater availability translates into a decrease in the full price of obtaining a meal, which contributes to greater consumption. Market-level data are used to estimate demand equations in two time periods, incorporating changes in availability as well as prices, income, and various demographic characteristics. Our findings show that greater availability has led to increased consumption. Failure to account for these types of marketplace changes could lead to incorrect inferences regarding the factors responsible for the industry growth.

description: We start by analysing the Lie algebra of Hermitian vector fields of a Hermitian line bundle. Then, we specify the base space of the above bundle by considering a Galilei, or an Einstein spacetime. Namely, in the first case, we consider, a fibred manifold over absolute time equipped with a spacelike Riemannian metric, a spacetime connection (preserving the time fibring and the spacelike metric) and an electromagnetic field. In the second case, we consider a spacetime equipped with a Lorentzian metric and an electromagnetic field. In both cases, we exhibit a natural Lie algebra of special phase functions and show that the Lie algebra of Hermitian vector fields turns out to be naturally isomorphic to the Lie algebra of special phase functions. Eventually, we compare the Galilei and Einstein cases.
Curriculum design for the high school credit program in Korean language at Sup sogŭi Hosu (Lake in the Woods), the Korean Language Village at Concordia Language Villages

description: This thesis concerns curriculum design for the high school credit program in Korean Language at Sup sogiii Hosu (Lake in the Woods), the Korean Language Village (KLV) at Concordia Language Villages (CLV). It reviews the main features and principles of the draft curriculum for the Korean Language Village 4-week high school credit program, evaluates the design based on the classroom results of the inaugural credit session, discusses the feasibility of a total immersion approach in Korean learning for speakers of English, and suggests further directions for Korean immersion curriculum development using WebCT tools. The entire draft curriculum, covering two years of high school curriculum, is presented as an appendix. Along with a general review of immersion, this study also contains a general review of CLV's educational philosophy and its actual program features, and suggests the critical role that KLV can play in facilitating Korean education in the U.S., where the need for more effective Korean language education is rapidly increased. The thesis also discusses the importance of Korean language education for the Korean adoptees who make up a significant portion of the KLV population, and calls for the reform of existing Korean education programs targeted mainly at 2n d generation Koreans in the U.S.

description: The influence of vacancies in the $C$ sub-lattice of $MgCNi_{3}$, on its structural, electronic and magnetic properties are studied by means of the density-functional based Korringa-Kohn-Rostoker Green's function method formulated in the atomic sphere approximation. Disorder is taken into account by means of coherent-potential approximation. Characterizations representing the change in the lattice properties include the variation in the equilibrium lattice constants, bulk modulus and pressure derivative of the bulk modulus, and that of electronic structure include the changes in the, total, partial and $\mathbf{k}$-resolved density of states. The incipient magnetic properties are studied by means of fixed-spin moment method of alloy theory, together in conjunction with the phenomenological Ginzburg-Landau equation for magnetic phase transition. The first-principles calculations reveal that due to the breaking of the $C$-$Ni$ bonds, some of the $Ni$ 3d states, which were lowered in energy due to strong hybridization, are transfered back to higher energies thereby increasing the itinerant character in the material. The Bloch spectral densities evaluated at the high symmetry points however reveal that the charge redistribution is not uniform over the cubic Brillouin zone, as new states are seen to be created at the $Γ$ point, while a shift in the states on the energy scale are seen at other high symmetry points.

description: This study estimates wholesale demand for pork, chicken, and quality differentiated beef. We estimate meat retailer own- and cross-price demand elasticities for USDA Choice and Select boxed beef. Results indicate that meat retailers have more elastic demand for lower quality graded beef. Retail beef price has a strong positive relationship with Choice and Select boxed beef demand, and a strong negative relationship with wholesale pork and chicken demand. Seasonal analysis reveals demand for both beef quality grades becomes highly price inelastic during the summer months. The two beef quality grades are substitutes during the winter; however, Select beef is not a substitute for Choice beef in the spring and summer.

description: The mechanism of wavefront reconstruction by a geometric-optical reflection of reconstructing light from surfaces with constant phase differences between the object and reference waves used to record the interference fringe structure in the medium bulk is analyzed. This mechanism is compared with the holographic one. Experiments in volume medium and in planar optical waveguide were carried out. Several types of achromatic optical elements are proposed. The optoacoustic focusing element, which can create a great local stress in a special shaped area inside the matter, is discussed. The possibility of the ultrashort pulse temporal reconstruction is demonstrated.

description: To understand how food stamps affect food spending, nonexperimental research typically requires some source of independent variation in food stamp benefits. Three promising sources are examined: (a) variation in household size, (b) variation in deductions from gross income, and (c) receipt of minimum or maximum food stamp benefits. Based on results of a linear regression model with nationally representative data, 90% of the total variation in food stamp benefits is explained by gross cash income, and household size variables alone. This finding raises concern about popular regression approaches to studying the Food Stamp Program.

description: A planetary atmosphere is the outer gas layer of a planet. Besides its scientific significance among the first and most accessible planetary layers observed from space, it is closely connected with planetary formation and evolution, surface and interior processes, and habitability of planets. Current theories of the planetary atmosphere were primarily obtained through the studies of eight large planets, Pluto and three large moons (Io, Titan, and Triton) in the Solar System. Outside the Solar System, more than four thousand extra-solar planets (exoplanets) and two thousand brown dwarfs have been confirmed in our galaxy, and their population is rapidly growing. The rich information from these exotic bodies offers a database to test, in a statistical sense, the fundamental theories of planetary climates. Here we review the current knowledge of atmospheres of exoplanets and brown dwarfs from recent observations and theories. This review highlights important regimes and statistical trends in an ensemble of atmospheres as an initial step towards fully characterizing diverse substellar atmospheres, that illustrates the underlying principles and critical problems. Insights are obtained through analysis of the dependence of atmospheric characteristics on basic planetary parameters. Dominant processes that influence atmospheric stability, energy transport, temperature, composition, and flow pattern are discussed and elaborated with simple scaling laws. We dedicate this review to Dr. Adam P. Showman (1968-2020) in recognition of his fundamental contribution to the understanding of atmospheric dynamics on giant planets, exoplanets, and brown dwarfs.

Share and share alike? : The value of pooling demand data across retail locations
Creators: name: Colby, Sarah M.
Publisher: name: University of British Columbia

description: We consider the value of pooling demand data across multiple retail outlets in a multiple-period newsvendor problem. In particular, our setting consists of a single firm with two newsvendor retail locations. The retailers each face normally distributed, stationary demand for a product. The variance of demand is known, but the mean is unknown and estimated. This estimate is updated as consumer demand at the retail locations is observed. We contrast the situation in which a central agent pools the retailers' demand data when updating the demand forecast with that when the retailers act with local data only. In a numerical study, we investigate the effects of the following factors on the value of pooling: (1) the relative size of the retailers' markets; (2) whether the product is a high-profit or a low-profit product; (3) the number of periods in the horizon; and (4) the forecast updating method. Further, we study the effects of these factors under a number of different scenarios characterized by the a priori beliefs about mean demand. Specifically, these scenarios represent initial beliefs about mean demand which are either overconfident, underconfident or reasonable. In our numerical study we find that the effect of the relative size of the retailers' markets on the value of pooling is not interesting. The value of pooling is greater for low-profit products than for high-profit products. As expected, pooling is more valuable when the a priori beliefs about mean demand are overconfident or underconfident than when they are reasonable. The effect of the forecast updating method on the value of pooling depends on the initial beliefs about mean demand. Likewise, the effect of the horizon length depends on the forecast updating method, as well as the initial beliefs about mean demand.

description: Firms selling products overseas may do so in a wide variety of ways, such a s through trading companies, foreign distributors, brokers, direct sales, license arrangements, and foreign direct investment. Many firms employ a portfolio of arrangements for each of their products. Using a share equation model, we examine the factors influencing food processing cooperatives' foreign business arrangements. Particularly important are the cooperative's financial resources and structure, risk exposure and risk preferences, information resources, and product types. Compared to investor-owned firms, we find that cooperatives have distinct disadvantages in investing or selling directly abroad, although the disadvantages are tempered by some equalizing considerations.
Precision Top Quark Mass Measurement in the Lepton + Jets Topology in ppbar Collisions at sqrt(s) = 1.96 TeV

description: We report two measurements of the top quark mass M_top using the CDF II detector at the Fermilab Tevatron in a 318 pb^-1 data sample observed in the lepton + jets final state. One method uses an event-based likelihood technique resulting in M_top = 173.2 +2.6/-2.4 (stat.) +/- 3.2 (syst.) GeV/c^2 or 173.2 +4.1/-4.0 GeV/c^2. The second method reconstructs a top quark mass in each event using the measured invariant mass of the hadronically decaying W boson to constrain the jet energy scale to obtain a value for M_top of 173.5 +3.7/-3.6 (stat.) +/- 1.3 (syst.) GeV/c^2 or 173.5 +3.9/-3.8 GeV/c^2. We take the latter, which is more precise, as our result.

Using quasar spectra from HST/COS and from Keck/HIRES or VLT/UVES we measure column densities of, or determine limits on, CGM absorption lines. We use a Markov chain Monte Carlo approach with Cloudy to estimate metallicities of cool ($T\sim10^4$K) CGM gas within groups and compare them to CGM metallicities of 47 isolated galaxies. Both group and isolated CGM metallicities span a wide range ($-2
