Subjects: Demand and Price Analysis

description: This paper classifies methods for estimating agricultural output supply responses to price into two broad categories (1) programming and (2) econometric. The latter category is further subdivided into two-stage procedures, directly estimated supply systems and directly estimated single commodity models. In Part 1 the theoretical basis of these methods is considered, while Part 2 explores their strengths, weaknesses and potentials from an empirical standpoint.

description: We explore the effectiveness of variational quantum circuits in simulating the ground states of quantum many-body Hamiltonians. We show that generic high-depth circuits, performing a sequence of layer unitaries of the same form, can accurately approximate the desired states. We demonstrate their universal success by using two Hamiltonian systems with very different properties: the transverse field Ising model and the Sachdev-Ye-Kitaev model. The energy landscape of the high-depth circuits has a proper structure for the gradient-based optimization, i.e. the presence of local extrema -- near any random initial points -- reaching the ground level energy. We further test the circuit's capability of replicating random quantum states by minimizing the Euclidean distance.

description: We investigate refined algebraic quantisation of the constrained Hamiltonian system introduced by Boulware as a simplified version of the Ashtekar-Horowitz model. The dimension of the physical Hilbert space is finite and asymptotes in the semiclassical limit to 1/(2π\hbar) times the volume of the reduced phase space. The representation of the physical observable algebra is irreducible for generic potentials but decomposes into irreducible subrepresentations for certain special potentials. The superselection sectors are related to singularities in the reduced phase space and to the rate of divergence in the formal group averaging integral. There is no tunnelling into the classically forbidden region of the unreduced configuration space, but there can be tunnelling between disconnected components of the classically allowed region.

Experiencing freefall: a journey of pedagogical possibilities
Creators: name: Haskell, Johnna Gayle
Publisher: name: University of British Columbia
Year: 2009

description: Experiencing Freefall is an inquiry into outdoor experiencing. It focuses on both my experiences with a group of Grade 10 students in an outdoor adventure education program and my personal experiencing of the outdoors. I explore the awareness we embody within moments of unexpected happenings while negotiating Whitewater rapids or searching for a handhold while clinging to the side of a cliff face. Also in this thesis I explore the 'phenomena of experiencing' which emerges out of our actions and interactions within outdoor activities. The challenge of this dissertation is capturing in prose, the phenomena of experiencing and 'embodied awareness' arising through such unexpected instances. Hence, the thesis, in trying to articulate the complexity of experiencing in the outdoors, uses stories, poetry and the metaphor of life, breath, and mountaineering to invite the reader on a journey of inquiry. This thesis escorts the reader, like a true pedagogue, into an outdoor environment of experiencing that opens the reader to ponder pedagogical possibilities. I explore several themes in the thesis which include 'freefall,' community, 'turning points,' and 'embodied respect' using a methodology of 'enactive inquiry.' The thesis takes a journey through each theme by weaving students' stories from the study, my own personal stories of the unexpected, and the theory of enaction. The thesis creates an opportunity for readers to embrace their own struggles, fears, and inquiry. Through the use of outdoor stories to illustrate moments of freefall into the unfamiliar or unknown, we may imagine pedagogical possibilities. As an enactive inquiry, this research thesis embodies an "education" or way of being, living, experiencing that explores unexpected happenings. In articulating an ecological perspective of experiencing, the thesis juxtaposes encounters in the outdoors with enactive theory to move beyond traditional representationalist models of cognition. Specifically, I focus on the embodied awareness that arises through phenomena of experiencing and its relation to pedagogy. The thesis contributes to the theory of the enactive approach by bringing examples of human experience which unfold, not only our interactions within the ecological web of the outdoor world, but an emergent space of pedagogical possibilities. As such, this thesis is an experiential work through which the reader may realize their own interpreting of possible pedagogies for many educational contexts.

Rural Employment and the Quality of Life

Year: 1983
Subjects: Labor and Human Capital

description: The nature of a person's employment, or lack of it, represents a critical factor influencing the quality of his life. The importance of employment arises not only from the income which work provides for an individual, but also from a variety of other attributes. This paper seeks to draw attention to the broader range of benefits which employment can generate and to consider their significance in the context of some areas of rural policy. After a brief discussion of the non-financial benefits of employment, it is argued that, if current trends continue, the relative importance of these benefits may be expected to increase. This would reduce the relevance of policy studies which ignore these issues and influence the appropriate organisation of some forms of economic activity. Part-time employment in the rural sector is highlighted as an area where these trends have already had important effects. The paper concludes with a consideration of the implications for adjustment policy and alternative lifestyles.

REMARKS
Recent molecular data have shown that these two species are actually an assemblage of at least five distinct evolutionary lineages, representing a morphological continuum covering the variation of the Nais communis / variabilis complex (Envall et al. 2012). No morphological revision of this complex has been carried out so far, which prevents an identification of these cryptic species otherwise than with molecular data. Although morphologically very similar, N. communis and N. variabilis are said to be different in their ability to swim (N. variabilis) or not (N. communis), and in an abrupt or gradual dilatation of oesophagus from VII (N. variabilis and N. communis, respectively) (Piguet 1906). On preserved material, only this last character can be assessed. In spite of uncertainties about the exact nature of both species, we tentatively distinguish our taxa (Table 1) on the basis of this character, pending an assessment of its discriminatory value in the future.

description: A recent experiment [Sadoon AA, Wang Y. 2018 Phys. Rev. E 98, 042411] has revealed that nucleoid associated proteins (i.e., DNA-binding proteins) exhibit highly heterogeneous diffusion processes in bacteria where not only the diffusion constant but also the anomalous diffusion exponent fluctuates for the various proteins. The distribution of displacements of such proteins is observed to take a q-Gaussian form, which decays as a power law. Here, a statistical model is developed for the diffusive motion of the proteins within the bacterium, based on a superstatistics with two variables. This model hierarchically takes into account the joint fluctuations of both the anomalous diffusion exponents and the diffusion constants. A fractional Brownian motion is discussed as a possible local model. Good agreement with the experimental data is obtained.

Economic Growth, Comparative Advantage and Agricultural Trade of Pacific Rim Countries

Year: 1983
Subjects: International Relations/Trade

description: While agriculture's contribution to national output and employment tends to decline with economic growth, its contribution to exports need not. Neoclassical theory suggests that a country's comparative advantage in agriculture depends on its endowment of agricultural land relative to mineral resources and nonfarm capital, compared with endowment ratios in other countries. Over time, a country's agricultural comparative advantage will decline faster, the faster its mineral extraction, its growth in nonfarm capital per worker and its rates of nonfarm relative to farm technological change, again compared with other countries. Empirical support for this theory is provided by evidence from the diverse set of economies on the Pacific rim. The paper concludes with a discussion of likely future trends in comparative advantage and agricultural trade of Pacific rim countries, particularly Australia.

description: A mass paucity of compact objects in the range of $\sim 2-5 ~M_\odot$ has been suggested by X-ray binary observations, namely, the "lower mass gap". Gravitational wave detections have unlocked another mass measurement method, and aLIGO/Virgo has observed some candidates in the gap. We revisit the numerical simulations on the core-collapse supernovae (CCSNe) for $\sim 20-40~M_\odot$ progenitor stars with differently initial explosion energies. As a result, the lower explosion energy naturally causes more efficient fallback accretion for low-metallicity progenitors, and then the newborn black holes (BHs) in the center of the CCSNe can escape from the gap, but neutron stars cannot easily collapse into BHs in the gap; nevertheless, the final remnants of the solar-metallicity progenitors stick to the gap. If we consider that only drastic CCSNe can be observed and that those with lower explosion energies are universal, the lower mass gap can be reasonably built. The width and depth of the gap are mainly determined by the typical CCSN initial explosion energy and metallicity. One can expect that the future multi-messenger observations of compact objects delineate the shape of the gap, which might constrain the properties of the CCSNe and their progenitors.

description: Let $ϕ: \R^d \longrightarrow \C$ be a compactly supported function which satisfies a refinement equation of the form $ϕ(x) = \sum_{k\inΛ} c_k ϕ(Ax - k),\quad c_k\in\C$, where $Γ\subset\R^d$ is a lattice, $Λ$ is a finite subset of $Γ$, and $A$ is a dilation matrix. We prove, under the hypothesis of linear independence of the $Γ$-translates of $ϕ$, that there exists a correspondence between the vectors of the Jordan basis of a finite submatrix of $L=[c_{Ai-j}]_{i,j\inΓ}$ and a finite dimensional subspace $\mathcal H$ in the shift invariant space generated by $ϕ$. We provide a basis of $\mathcal H$ and show that its elements satisfy a property of homogeneity associated to the eigenvalues of $L$. If the function $ϕ$ has accuracy $κ$, this basis can be chosen to contain a basis for all the multivariate polynomials of degree less than $κ$. These latter functions are associated to eigenvalues that are powers of the eigenvalues of $A^{-1}$. Further we show that the dimension of $\mathcal H$ coincides with the local dimension of $ϕ$, and hence, every function in the shift invariant space generated by $ϕ$ can be written locally as a linear combination of translates of the homogeneous functions.

Induced Innovation in the High Rainfall Zone

Publisher: name: Unknown
Year: 1982
Subjects: Research and Development/Tech Change/Emerging Technologies

description: The induced innovation hypothesis states that the direction of technical change is determined by changes in relative input prices acting as a "spur to invention". To determine the validity of this hypothesis for the High Rainfall Zone of the Australian sheep industry, technical change biases for five input categories were measured using time series data for the period 1952-53 to 1976-77. These biases were then related to relative changes in the price of these input categories. The biases were measured by the application of a translog cost function model and suggested that, in general, technical change has been biased toward the saving of labour and land, the using of livestock, and neutral in regard to capital, and possibly materials and services. Comparison of the ranking of the measured biases with that of the relative price changes indicated that all results, except those for capital, were in general conformity with the induced innovation hypothesis. Finally, the deficiencies of the model and implications of the results are discussed.

description: We have studied the magnetic characteristics of a series of super-oxygenated La2-xSrxCuO4+y samples. As shown in previous work, these samples spontaneously phase separate into an oxygen rich superconducting phase with a TC near 40 K and an oxygen poor magnetic phase that also orders near 40 K. All samples studied are highly magnetically reversible even to low temperatures. Although the internal magnetic regions of these samples might be expected to act as pinning sites, our present study shows that they do not favor flux pinning. Flux pinning requires a matching condition between the defect and the superconducting coherence length. Thus, our results imply that the magnetic regions are too large to act as pinning centers. This also implies that the much greater flux pinning in typical La2-xSrxCuO4 materials is the result of nanoscale inhomogeneities that grow to become the large magnetic regions in the super-oxygenated materials. The superconducting regions of the phase separated materials are in that sense cleaner and more homogenous than in the typical cuprate superconductor.

description: Agricultural nitrogen losses are the major contributor to nitrogen loads in the Mississippi River, and consequently, to the existence of a hypoxic, or "dead", zone in the Gulf of Mexico. Focusing on two small agricultural watersheds in southeast Minnesota, simulation results from the Agricultural Drainage And Pesticide Management (ADAPT) model were combined with a linear-optimization model to evaluate the environmental and economic impact of alternative land-use policies for reducing nitrogen losses. Of particular importance was the study's explicit focus on agricultural subsurface (tile) drainage, which has been identified as the major pathway for agricultural nitrogen losses in the upper Midwest, and the use of drainage-focused abatement policies. Results indicate that tile-drained land plays a key role in nitrogen abatement, and that a combined policy of nutrient management on tile-drained land and retirement of non-drained land is a cost-effective means of achieving a 20- or 30-percent nitrogen-abatement goal. Results also indicate that although it is cost-effective to abate on tile-drained land, it is not cost-effective to undertake policies that plug or remove tile drains from the landscape, regardless of whether the land would be retired or kept in production. Therefore, results imply that although tile-drained land is a major source of nitrogen lost to waterways, it is not cost-effective to remove the land from production or to remove the drainage from the land. Because of its value to agricultural production, it is better to keep tile-drained land in production under nutrient management and focus retirement policies on relatively less-productive, non-drained acres.

description: Using the standard Bardeen-Cooper-Schrieffer (BCS) theory, we revise microscopic derivation of the superconductor-insulator boundary conditions for the Ginzburg-Landau (GL) model. We obtain a negative contribution to free energy in the form of surface integral. Boundary conditions for the conventional superconductor have the form $\textbf{n} \cdot \nabla ψ= \text{const} ψ$. These are shown to follow from considering the order parameter reflected in the boundary. The boundary conditions are also derived for more general GL models with higher-order derivatives and pair-density-wave states. It shows that the boundary states with higher critical temperature and the boundary gap enhancement, found recently in BCS theory, are also present in microscopically-derived GL theory. In the case of an applied external field, we show that the third critical magnetic-field value $H_{c3}$ is higher than what follows from the de Gennes boundary conditions and is also significant in type-I regime.

description: Intrahousehold analyses provide new insights into how households make economic decisions. Much of the work in economics has traditionally treated the household as a single economic actor, but a number of studies are providing evidence that the dynamics among household members affect the outcomes of household economic decisions. This paper contributes to our understanding of such models by incorporating the variability of individual incomes into the analysis of intrahousehold resource allocations, using detailed household survey data from Ghana.

description: We give a formal algebraic description of Josephson-type quantum dynamical systems, i.e., Hamiltonian systems with a cos theta-like potential term. The two-boson Heisenberg algebra plays for such systems the role that the h(1) algebra does for the harmonic oscillator. A single Josephson junction is selected as a representative of Josephson systems. We construct both logical states (codewords) and logical (gate) operators in the superconductive regime. The codewords are the even and odd coherent states of the two-boson algebra: they are shift-resistant and robust, due to squeezing. The logical operators acting on the qubit codewords are expressed in terms of operators in the enveloping of the two-boson algebra. Such a scheme appears to be relevant for quantum information applications.

Two different types of vortex have been detected. The outward vortex first penetrates the particle near its centerline then, on exiting the particle, the flow-lines turn away from the centerline and enter a spiral trajectory. Outward vortexes are seen for the wavelengths shorter then the plasmon resonance. For the wavelengths longer that the plasmon resonance the vortex is inward: the power-flow lines pass around the sides of the particle before turning towards the centerline and entering the particle to begin their spiral trajectory.

description: We present the direct detection of the splashback feature using the sample of massive galaxy clusters from the Local Cluster Substructure Survey (LoCuSS). This feature is clearly detected (above $5σ$) in the stacked luminosity density profile obtained using the K-band magnitudes of spectroscopically confirmed cluster members. We obtained the best-fit model by means of Bayesian inference, which ranked models including the splashback feature as more descriptive of the data with respect to models that do not allow for this transition. In addition, we have assessed the impact of the cluster dynamical state on the occurrence of the splashback feature. We exploited the extensive multi-wavelength LoCuSS dataset to test a wide range of proxies for the cluster formation history, finding the most significant dependence of the splashback feature location and scale according to the presence or absence of X-ray emitting galaxy groups in the cluster infall regions. In particular, we report for the first time that clusters that do not show massive infalling groups present the splashback feature at a smaller clustercentric radius $ r_{\rm{sp}}/r_{\rm{200,m}} = 1.158 \pm 0.071$ than clusters that are actively accreting groups $r_{\rm{sp}}/r_{\rm{200,m}} = 1.291 \pm 0.062$. The difference between these two sub-samples is significant at $4.2σ$, suggesting a correlation between the properties of the cluster potential and its accretion rate and merger history. Similarly, clusters that are classified as old and dynamically inactive present stronger signatures of the splashback feature, with respect to younger, more active clusters. We are directly observing how fundamental dynamical properties of clusters reverberate across vastly different physical scales.

description: Gravitational lensing effects arise from the light ray deflection by all of the mass distribution along the line of sight. It is then expected that weak lensing cluster surveys can provide us true mass-selected cluster samples. With numerical simulations, we analyze the correspondence between peaks in the lensing convergence $κ$-map and dark matter halos. Particularly we emphasize the difference between the peak $κ$ value expected from a dark matter halo modeled as an isolated and spherical one, which exhibits a one-to-one correspondence with the halo mass at a given redshift, and that of the associated $κ$-peak from simulations. For halos with the same expected $κ$, their corresponding peak signals in the $κ$-map present a wide dispersion. At an angular smoothing scale of $θ_G=1\hbox{arcmin}$, our study shows that for relatively large clusters, the complex mass distribution of individual clusters is the main reason for the dispersion. The projection effect of uncorrelated structures does not play significant roles. The triaxiality of dark matter halos accounts for a large part of the dispersion, especially for the tail at high $κ$ side. Thus lensing-selected clusters are not really mass-selected. (abridged)

description: The objective of this paper is to explore commercial bank participation in the farm real estate loan market. We do that primarily through a review and analysis of recent bank survey and secondary data. We briefly consider some of the changes in economic conditions (e.g., farm income levels, interest rates and land values) which influence the demand for farm real estate loans. This leads to a consideration of some hypotheses about the importance of competitiveness and customer loyalty at commercial banks in shaping how banks compete. In the subsequent sections we discuss the bank survey results and our analysis of that data from the perspective of bank competitiveness and customer loyalty as explanations for the observed trend in farm real estate market shares.

description: We study the quasi--elastic contribution to the inclusive $(ν_l,ν_l N)$, $(ν_l,l^- N)$, $({\bar ν}_l,{\bar ν}_l N)$ and $({\bar ν}_l,l^+ N)$ reactions in nuclei using a Monte Carlo simulation method to account for the rescattering of the outgoing nucleon. As input, we take the reaction probability from the microscopical many body framework developed in Phys. Rev. {\bf C70} (2004) 055503 for charged-current induced reactions, while for neutral currents we use results from a natural extension of the model described in that reference. The nucleon emission process studied here is a clear signal for neutral--current neutrino driven reactions, that can be used in the analysis of future neutrino experiments.

Superconductivity at 17 K in Yttrium Metal under Nearly Hydrostatic Pressures to 89 GPa

description: In an experiment in a diamond anvil cell utilizing helium pressure medium, yttrium metal displays a superconducting transition temperature which increases monotonically from Tc ? 3.5 K at 30 GPa to 17 K at 89.3 GPa, one of the highest transition temperatures for any elemental superconductor. The pressure dependence of Tc differs substantially from that observed in previous studies under quasihydrostatic pressure to 30 GPa. Remarkably, the dependence of Tc on relative volume V/Vo is linear over the entire pressure range above 33 GPa, implying that higher values of Tc are likely at higher pressures. For the trivalent metals Sc, Y, La, Lu there appears to be some correlation between Tc and the ratio of the Wigner-Seitz radius to the ion core radius.

description: We study metric-affine gravity (MAG) inspired cosmological models. Those models were statistically estimated using the SNIa data. We also use the cosmic microwave background observations and the big-bang nucleosynthesis analysis to constrain the density parameter $Ω_{ψ,0}$ which is related to the non-Riemannian structure of the underlying spacetime. We argue that while the models are statistically admissible from the SNIa analysis, complementary stricter limits obtained from the CMB and BBN indicate that the models with density parameters with a $a^{-6}$ scaling behaviour are virtually ruled out. If we assume the validity of the particular MAG based cosmological model throughout all stages of the Universe, the parameter estimates from the CMB and BBN put a stronger limit, in comparison to the SNIa data, on the presence of non-Riemannian structures at low redshifts.

description: This paper attempts to improve our understanding of the effects of market prices on cattle marketing decisions, using futures prices as measures of unobserved price expectations. This approach has been used successfully in explaining feeder cattle placements, but not in marketings. Our aim is to provide empirical evidence on an unresolved issue in cattle marketing, the differential effects of the current price and near-term price expectations. When the cash price of fed cattle rises, the higher returns from current sales encourage increased marketings; yet, if the price is expected to remain high it may pay to feed cattle longer, holding them back from current marketing. By estimating marketings as a function of cash and futures prices simultaneously we hope to separate these two effects.

description: We present a new calculation for the production of isolated photon pairs at the LHC with NNLL$'_{\mathcal{T}_0}$+NNLO accuracy. This is the first implementation within the GENEVA Monte Carlo framework of a process with a nontrivial Born-level definition which suffers from QED singularities. Throughout the computation we use a smooth-cone isolation algorithm to remove such divergences. The higher-order resummation of the 0-jettiness resolution variable $\mathcal{T}_0$ is based on a factorisation formula derived within Soft-Collinear Effective Theory which predicts all of the singular, virtual and real NNLO corrections. Starting from this precise parton-level prediction and by employing the GENEVA method, we provide fully showered and hadronised events using PYTHIA8, while retaining the NNLO QCD accuracy for observables which are inclusive over the additional radiation. We compare our final predictions to LHC data at 7 TeV and find good agreement.

description: In the spacetime of n-dimensional static charged black hole we examine the mechanism by which the self-interacting scalar hair decay. It is turned out that the intermediate asymptotic behaviour of the self-interacting scalar field is determined by an oscilatory inverse power law. We confirm our results by numerical calculations.

description: We study the resummation of large logarithmic QCD corrections for the process pp ->H+ X when the Higgs boson H is produced at high transverse momentum. The corrections arise near the threshold for partonic reaction and originate from soft gluon emission. We perform the all-order resummation at next-to-leading logarithmic accuracy and match the resummed result with the next-to-leading order perturbative predictions. The effect of resummation on the Higgs transverse momentum distribution at the LHC is discussed.

description: We present results for the 2-jettiness differential distribution for boosted top quark pairs produced in $e^+e^-$ collisions in the peak region accounting for QCD large-logarithm resummation at next-to-next-to-next-to-leading logarithmic (N$^3$LL) order and fixed-order corrections to matrix elements at next-to-next-to-leading order (NNLO) calculated in the framework of soft-collinear effective theory and boosted heavy quark effective theory. Electroweak and finite-width effects are included at leading order. We study the perturbative convergence of the cross section in the pole and MSR mass schemes, with and without soft gap subtractions. We find that there is a partial cancellation between the pole mass and soft function renormalons. When renormalon subtractions concerning the top mass and the soft function are implemented, the perturbative uncertainties are, however, systematically smaller and an improvement in the stability of the peak position is observed. We find that the top MSR mass may be determined with perturbative uncertainties well below $100$\,MeV from the peak position of the 2-jettiness distribution. This result has important applications for Monte Carlo top quark mass calibrations.

description: The dynamics of spin-lattice relaxation of the Mn-ions in (Zn,Mn)Se-based diluted-magnetic-semiconductor quantum wells is studied by time-resolved photoluminescence. The spin-lattice relaxation time varies by five orders of magnitude from 10-3 down to 10-8 s, when the Mn content increases from 0.4 up to 11%. Free carriers play an important role in this dynamics. Hot carriers with excess kinetic energy contribute to heating of the Mn system, while cooling of the Mn system occurs in the presence of cold background carriers provided by modulation doping. In a Zn0.89Mn0.11Se quantum well structure, where the spin-lattice relaxation process is considerably shorter than the characteristic lifetime of nonequilibrium phonons, also the phonon dynamics and its contribution to heating of the Mn system are investigated.
