description: The rise of contract farming and vertical integration is one of the most important changes in modern agriculture. Yet the adoption and diffusion of these new forms of organization has varied widely across regions, commodities, or farm types, however. Transaction cost theories and the like are not fully effective at explaining the variation of adoption rates of different organizational forms, in part because of their inherent static nature. In order to explain the adoption, diffusion and evolution of organizational form, a more dynamic framework is required. This paper lays out such a framework for understanding the evolution of organizational practices in U.S. agriculture by drawing on existing theories of economic organization, the diffusion of technological innovation, and organizational complementarities. Using recent trends as stylized facts we argue that the agrifood sector is characterized by strong complementarities among its constituent features and that these complementarities help explain the stylized facts. We also discuss several testable hypotheses concerning changes in organizational form in agriculture.

description: Agricultural zoning and land use restrictions are long-standing approaches for controlling non-agricultural development. Agricultural landowners may contest agricultural zoning if they expect zoning to reduce land prices on restricted land. However, it is common to find agricultural landowners on both sides of this issue. A prevailing economic explanation for variation in landowner support is that the price effect of zoning varies across land parcels and therefore, zoning may increases the value of some lands zoned for agricultural use. In this paper, we provide an additional explanation for variation in agricultural landowner support. We use the concepts of net buyers and net sellers of land to suggest that the utility effect of changing land prices depends on an agricultural landowner's position in the agricultural land market. Hence, even in situations where all agricultural landowners expect zoning to reduce agricultural land prices, some subset of agricultural landowners - i.e., net buyers - may benefit. Survey data from agricultural landowners is used to model the probability that an agricultural landowner will support agricultural zoning. The empirical findings are consistent with our hypothesis that net buyers and net sellers of agricultural land will differ in their support for agricultural zoning.

description: Here can be seen a few items belonging to Lieutenant Arthur Henry Brown; at the time, he was a 24-year-old Second Lieutenant.

Arthur Henry Brown was born in Sussex, on the 27th of May 1894. His civilian occupiation was that of a bookseller assistant. He enlisted in the Territorial Force in 1911 for a four-year contract in the 5th Sussex Battery, Royal Field Artillery, aged 17, with the rank of Driver (Private - in the RFA, the one leading the horses pulling the gun). He had already been in the cadet corps of the Church Lads Brigade.

In 1914 he signed an agreement to be sent overseas for war purposes. He seems to have been stationed in England and India for most of the war. He was promoted Bombardier (Lance Corporal), then Corporal, then Orderly Room Sergeant (a temporary commission) and finally Sergeant in his final days in India. In 1917, bearing that latter rank, he re-enlisted after the end of his contract.

From June 1917 to February 1918, he served at home; but the reason for that is that the British army needing more officers due to the more experienced ones dying at the front. This experienced Sergeant was required to follow cadet officer training in Exeter, where he met his future wife.

Promoted to the rank of 2nd Lieutenant in February 1918, he was sent to France for the last - and vital - fights of the war. (That is the period concerned by those documents). He kept serving until September 1919, when he resigned his commission on medical grounds. Nonetheless, he had been promoted without his knowledge to the rank of 1st Lieutenant in August of that year, and was allowed to retain this rank.

He was awarded the Interallied Medal, the 1914-15 Star, the British War Medal and the Territorial Force War Medal.

description: GeAs is a layered material of the IV-V groups that is attracting growing attention for possible applications in electronic and optoelectronic devices. In this study, exfoliated multilayer GeAs nanoflakes are structurally characterized and used as the channel of back-gate field-effect transistors. It is shown that their gate-modulated p-type conduction is decreased by exposure to light or electron beam. Moreover, the observation of a field emission current demonstrates the suitability of GeAs nanoflakes as cold cathodes for electron emission and opens up new perspective applications of two-dimensional GeAs in vacuum electronics. Field emission occurs with a turn-on field of ~80 V/μm and attains a current density higher than 10 A/cm^2, following the general Fowler-Nordheim model with high reproducibility.

description: Housing growth in Tennessee that incorporates spatial spillover and spatial heterogeneity at the level of census-block group is projected. A deterministic interpolation technique is adopted to create alternative neighborhood variables that captures spatial spillover of neighborhood effects on housing growth without multicollinearity. The maps drawn using the geographically weighted regression parameter estimates revealed that the local marginal effect of the housing price increases on housing growth gradually increases as one moves eastward. The population growth in the adjacent neighborhood-block group has about 10% of marginal effect of population growth in its own block group. The marginal effect of population growth is relatively higher in the approximate area of Cumberland Plateau while the local marginal effect of spatial spillover of population growth in adjacent neighbor is relatively higher in the East Tennessee and also the area South of Nashville.

description: The presence or absense of renormalon singularities in the Borel plane is shown to be determined by the analytic properties of the Gell-Mann - Low function β(g) and some other functions. A constructive criterion for the absense of singularities consists in the proper behavior of the βfunction and its Borel image B(z) at infinity, β(g)\sim g^αand B(z)\sim z^αwith α\le 1. This criterion is probably fulfilled for the ϕ^4 theory, QED and QCD, but is violated in the O(n)-symmetric sigma model with n\to\infty.

We employ our algorithm to sample the energy distribution for several spin-glasses and we demonstrate the superiority of our algorithm to the conventional MH algorithm in sampling and in annealing optimization.

Analytical results show that purity standards affect the equilibrium prices and quantities of both the GM and non-GM products as well as the welfare of the groups involved. A change in purity standards is shown to create winners and losers among the consumers as well as among the suppliers of the GM and conventional products.
The physics of dense hadronic matter and compact stars

Subjects: subject: Nuclear Theory (nucl-th)

description: This review describes the properties of hadronic phases of dense matter in compact stars. The theory is developed within the method of real-time Green's functions and is applied to study of baryonic matter at and above the saturation density. The non-relativistic and covariant theories based on continuum Green's functions and the T-matrix and related approximations to the self-energies are reviewed. The effects of symmetry energy, onset of hyperons and meson condensation on the properties of stellar configurations are demonstrated on specific examples. Neutrino interactions with baryonic matter are introduced within a kinetic theory. We concentrate on the classification, analysis and first principle derivation of neutrino radiation processes from unpaired and superfluid hadronic phases. We then demonstrate how neutrino radiation rates from various microscopic processes affect the macroscopic cooling of neutron stars and how the observed X-ray fluxes from pulsars constrain the properties of dense hadronic matter.

description: In this paper we present a continuous time optimal control analysis of resistance buildup in agricultural chemicals when the supplier is a monopolist. We compare the monopolistic, competitive and socially optimal solutions after establishing the stability of each equilibrium. The central finding is that with a monopolistic supplier, resistance buildup is lower than socially optimal. This directly opposes the standard result in the resistance literature. This implies that policies to manage resistance should vary with the age of the chemical, with no intervention during the lifetime of a patent and an optimal tax once the patent expires.

Considering the equations of motion of rodlike polymers in wall-bounded turbulent ensembles, we show that although the microscopic mechanism of attaining the MDR is very different, the macroscopic theory is isomorphic, rationalizing the interesting experimental observations.

description: The low-temperature behavior of the static magnetic susceptibility $χ(T)$ of exchange-disordered antiferromagnetic spin chains is investigated. It is shown that for a relatively small and even number of spins in the chain, two exchange distributions which are expected to occur in nanochains of P donors in silicon lead to qualitatively distinct behaviors of the low-temperature susceptibility. As a consequence, magnetic measurements might be useful to characterize whether a given sample meets the requirements compatible with Kane's original proposalfor the exchange gates in a silicon-based quantum computer hardware. We also explore the dependence of $χ(T)$ on the number of spins in the chain as it increases towards the thermodynamic limit, where any degree or distribution of disorder leads to the same low-temperature scaling behavior. We identify a crossover regime where the two distributions of disorder may not be clearly differentiated, but the characteristic scaling of the thermodynamic limit has not yet been reached.

description: We present a general strategy for the inverse design of metasurfaces composed of elementary shapes. We use it to design a structure that collects and collimates light from nitrogen-vacancy centers in diamond. Such metasurfaces constitute scalable optical interfaces for solid-state qubits, enabling efficient photon coupling into optical fibers and eliminating free-space collection optics. The many-body shape optimization strategy is a practical alternative to topology optimization that explicitly enforces material and fabrication constraints throughout the optimization, while still achieving high performance. The metasurface is easily adaptable to other solid-state qubits, and the optimization method is broadly applicable to fabrication-constrained photonic design problems.

description: Quantum technology can enable secure communication for cryptography purposes using quantum key distribution. Quantum key distribution protocols provide a secret key between two users with security guaranteed by the laws of quantum mechanics. To define the proper implementation of a quantum key distribution system using a particular cryptography protocol, it is crucial to critically and meticulously assess the device's performance due to technological limitations in the components used. We perform simulations on the ANSYS Interconnect platform to characterise the practical implementation of these devices using distributed-phase-reference protocols differential-phase-shift and coherent-one-way quantum key distribution. Further, we briefly describe and simulate some possible eavesdropping attempts, backflash attack, trojan-horse attack and detector-blinding attack exploiting the device imperfections.

Measurement of low mass dielectron continuum in sqrt(s_NN)=200GeV Au+Au collisions with the PHENIX experiment at RHIC

Publisher: name: arXiv
Year: 2005
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: Electromagnetic probes are ideally suited to investigate hot and dense matter produced in high energy heavy ion collisions. They do not undergo strong interactions and thus probe the time evolution of the collision. The dielectron continuum is rich in physics. Dalitz decays of light hadrons and direct decays of vector mesons, which might be modified in the medium, and correlated charm decays contribute to the spectrum. Furthermore, exotic states, e.g quasi-particles predicted to exist in the medium only beyond the phase transition, might leave their footprint in the continuum. Although correlated e+e- pairs are rare, the 0.24 nb^-1 collected by PHENIX for Au+Au collisions at sqrt(s_NN)= 200 GeV in 2004 provides a significant sample to investigate the dilepton continuum. The continuum and its resonances are separated from the combinatorial background via an event mixing technique. Mass spectra are presented and compared with the expectations from decays of hadronic sources.

description: A recursive method is developed to treat electrons coupled to phonons. It is applied to small systems with $E\otimesβ$ Jahn-Teller coupling. Two cases are considered, a model with one electron and two orbitals on a single site (related to the Rabi Hamiltonian) and a model with two electrons on two sites. The corresponding Green's functions are represented by rational functions. It is found that the spectra change substantially when one phonon couples to the electron but are relatively robust under an increasing number of phonons.

description: Hexagonal oxide perovskites, in contrast to the more familiar perovskites, allow for face-sharing of metal-oxygen octahedra or trigonal prisms within their structural frameworks. This results in dimers, trimers, tetramers, or longer fragments of chains of face-sharing octahedra in the crystal structures, and consequently in much shorter metal-metal distances and lower metal-oxygen-metal bond angles than are seen in the more familiar perovskites. The presence of the face-sharing octahedra can have a dramatic impact on magnetic properties of these compounds, and dimer-based materials, in particular, have been the subjects of many quantum-materials-directed studies in materials physics. Hexagonal oxide perovskites are of contemporary interest due to their potential for geometrical frustration of the ordering of magnetic moments or orbital occupancies at low temperatures, which is especially relevant to their significance as quantum materials. As such, several hexagonal oxide perovskites have been identified as potential candidates for hosting the quantum spin liquid state at low temperatures. In our view, hexagonal oxide perovskites are fertile ground for finding new quantum materials. This review briefly describes the solid state chemistry of many of these materials.

description: PtSe$_2$ ultrathin films are used as the channel of back-gated field-effect transistors (FETs) that are investigated at different temperatures and under super-continuous white laser irradiation. The temperature-dependent behavior confirms the semiconducting nature of multilayer PtSe$_2$, with p-type conduction, a hole field-effect mobility up to 40 cm2/(Vs) and significant gate modulation. Electrical conduction measured along different directions shows isotropic transport. A reduction of PtSe$_2$ channel conductance is observed under exposure to light. Such negative photoconductivity is explained by a photogating effect caused by photo-charge accumulation in SiO$_2$ and at the Si/SiO$_2$ interface.

description: Since processed foods are the fastest growing segment of U.S. agricultural exports, it is imperative to understand the underlying factors behind this growth. The overall objective of this research is to examine demand for processed foods by low and middle-income countries, seeking to assess demand determinants and potential import growth. In order to achieve this objective, we estimated a "modified gravity model" for U.S. exports of processed foods to 10 low and middle-income countries from 1980-2002, using both classical linear regression and fixed effects approaches. Empirical results from the classical model indicate that, as hypothesized, population, income, level of urbanization and an open trade regime have a positive effect on demand for processed foods by low and middle-income countries. As expected, exchange rates and distance have an inverse relationship with imports. Empirical results from the fixed-effects model are similar, with the exception of population. A cross-country comparative analysis of leading potential markets for U.S. processed food exports over the years 2003-2012 concluded that Mexico, China and Brazil, in that order, are likely to be the three largest future markets for U.S. processed foods among these 10 emerging countries.

Abell 43, a "hybrid-PG 1159" type star, is the second pulsator of this class, after HS 2324+3944. From the limited data set aquired, we find that Abell 43 exhibits at least two periods of 2600s and 3035s, the longest ones observed up to now in PG 1159 and "hybrid-PG 1159" pulsators. This strongly suggests that the variations are due to non-radial g-mode pulsations and cannot be a consequence of binarity. This discovery raises puzzling questions regarding the exitation mechanism in this H rich, C and O poor "hybrid-PG 1159" since the C and O abundances are too low to trigger the instability through the $κ$-mechanism invoked to explain the instability in the PG 1159 stars and in the previously known "hybrid-PG 1159" pulsator HS 2324+3944.

description: This paper develops an extended general equilibrium model of international trade in order to analyze the welfare effects of agricultural trade liberalization if a large country influences its terms of trade by means of environmental policy. We derive globally optimal first-best and second-best environmental and trade policy combinations as a benchmark for assessing the trade-distorting character of strategically motivated environmental policies and demonstrate that if second-best rather than first-best policies are chosen as a benchmark the conclusions may differ not only in magnitude but also in direction. We further demonstrate that if a Pigouvian instrument is transformed into a strategic environmental policy, following trade liberalization, the global welfare effect is unambiguously positive. We thereby prove that the distorting effect of an optimal tariff is generally greater than that of a strategically motivated environmental policy.

description: The quasi-option value (QOV) literature originated by Arrow and Fisher (1974) and by Henry (1974) is largely concerned with the analysis of two-period models of land development. Our paper extends this literature by analyzing two scenarios in which the decision to develop land is made in a multi-period and stochastic framework. In the first scenario, the development decision is indivisible. In contrast, in the second scenario, the development decision is divisible. Specifically, we study the properties of the indivisible development decision when there is a time constraint on when land is to be developed. We then analyze the ways in which the divisible land development decision depends on the extent of a landowner's landholding and on the number of development opportunities awaiting this landowner.

description: A regression model was used to investigate the determinants of soil nutrient depletion in Uganda. The major determinants of soil nutrient balances are household endowments, access to markets, and extension services, non-farm activities and agricultural potential. The results suggest the need to address soil nutrient depletion using multi-sectoral approaches.
Scalar field unification of interacting viscous dark fluid from a geometrical scalar-tensor theory of gravity

description: We investigate, in the framework of a recently introduced new class of invariant geometrical scalar-tensor theory of gravity, the possibility that a viscous dark fluid can be described in a unified manner by a single scalar field. Thus we developed a model in which both the metric tensor and the scalar field have geometrical origin. The scalar field is characterized by a non-canonical kinetic term and the scalar viscosity of the dark fluid appears as soon the kinetic energy of the scalar field is no longer canonical. The scalar viscosity is considered as a function of the Hubble and the deceleration parameters. To illustrate the formalism we have considered two cases: a constant and a thermodynamic equation of state parameters. In the both cases we obtain analytic representations for the scalar field and their respective potentials. We delimit free parameters by comparing with some Planck 2018 results.

Non-global logarithms up to four loops at finite-N$_c$ for V/H+jet processes at hadron colliders

description: We extend our previous work [1] on calculating non-global logarithms in $e^+ e^-$ annihilation to Higgs/vector boson production in association with a single hard jet at hadron colliders. We analytically compute non-global coefficients in the jet mass distribution up to four loops using the anti-k$_t$ jet algorithm. Our calculations are performed in the eikonal approximation, assuming strong energy ordering for the emitted gluons, thus capturing only the leading logarithms of the distribution. We compare our analytical results with the all-orders large-N$_c$ numerical solution. In general, the gross features of the non-global logarithm distribution observed in the $e^+ e^-$ case remain valid for the V/H+jet processes.

Including the excluded : a minority conception of standing
Creators: name: Binch, Russell John
Publisher: name: University of British Columbia

description: In 1986, the Supreme Court of Canada cogently summarized various judicial concerns relating to the expansion of public interest standing. In doing so, the Supreme Court invited judges to engage in a purposive and functional enquiry in exercising their discretion to grant access to public interest litigants. That enquiry should take account of the broad social, political and legal factors that provide the backdrop to the constitutional claim. However, both judges and commentators alike have failed to meet this challenge. Instead, they have applied the principles of standing in an increasingly categorical and abstract manner. To this end, they have employed the abstractly defined, directly affected individual without considering who he or she is in the particular circumstances, or what benefits he or she would bring to the litigation process. This is of particular concern when our context is inequality. The increasing abstraction of public interest standing jars discordantly with the purposive interpretation of section 15(1) of the Charter, so that while equality is determined in a contextual fashion, equal access is still conceived of in an abstract fashion. In abstracting the directly affected individual out of relations of radical inequality, there has been a presumption that we all, as individuals, have an equal opportunity (and equal resources) to raise our constitutional concerns in the courts. This presumption cannot be accepted. We need to inject some context into standing. To do so, we must appreciate that inequality is a product of the distribution of power in society, and that equality is to be furthered through multi-dimensionality and respect for diversity. Armed with these insights, we must revisit the judicial concerns that underpin the development of the public interest standing doctrine, and unpack their meaning in a purposive fashion. When we do so, we will begin to appreciate that the traditional resolution of these concerns actually serves to exclude disadvantaged persons from enforcing their Charter rights and obscures the diffuse causality characteristics of disadvantage. From the contextual perspective of social-inequality-as-power, the concerns underpinning public interest standing actually promote judicial access for the public interest organization that represents disadvantaged persons.

Testing a theoretical prediction for bar formation in galaxies with bulges

description: Earlier studies have shown that massive bulges impede bar formation in disk galaxies. Recent N-body simulations have derived a bar formation criterion that depends on the radial bulge force in a galaxy disk. We use those simulations to show that bars can form only when the force constant FB < 0.13, where FB depends on the ratio of the bulge force to the total force of the galaxy at twice the disk scale length 2R d . In this article, we test this theoretical prediction using observational data obtained from the literature. Our sample consists of 63 barred galaxies with a wide range of Hubble classes from the S 4 G catalogue for which bulge, disk and bar decomposition has been done. We find that 92 % of our sample galaxies satisfy the condition FB < 0.13 for bar formation in galaxies and hence agree with the bar formation criterion given by the simulations.
