Production Economics

description: In this article, we present empirical evidence to show that a commonly held belief is likely false. Specifically, we examine the claim that three widely used dairy technologies and management practices complement the use of rbST in the sense that they increase the marginal return of rbST. Using the definition described in Milgrom and Roberts (1990) that the presence of supermodular profit or total output functions is evidence of complementarity, our results show that the use of a computerized feeding system or total mixed ration feed balance system is complementary with the use of rbST, but that this complementarity only exists for when considering the effects on feed costs per cow. We are unable to detect any complementary relationships for operating margins per hundredweight of milk, operating margins per cow, or feed costs per hundredweight of milk. These results show that having a TMR feed balance system, being a member in a DHIA, or using a computerized feed system do not necessarily increase the marginal productivity or profitability of using rbST. This paper is the first to our knowledge that uses the production function approach to estimate econometrically whether complementarities among dairy technologies exist.

description: We analyze the link between large and destructive floods and armed conflict in 117 countries between 1985 and 2009 employing flood-induced migration as a potential transmission channel. We use rainfall as an instrument for flood-induced migration and employ a two step procedure (Rivers and Vuong 1988) to estimate the model. We find that floods are likely to increase the risk of armed conflict through the channel of migration.

description: Local structure can have important effects on luminosity distance observations, which could for example affect the local estimation of the Hubble constant based on low red-shift type Ia supernovae. Using a spherically symmetric exact solution of the Eistein's equations and a more accurate expansion of the solution of the geodesic equations, we improve the low red-shift expansion of the monopole of the luminosity distance in terms of the curvature function. Based on this we derive the coordinate independent low red-shift expansion of the monopole of the luminosity distance in terms of the monopole of the density contrast. The advantage of this approach is that it relates the luminosity distance directly to density observations, without any dependency on the radial coordinate choice. We compute the effects of different inhomogeneities on the luminosity distance, and find that the formulae in terms of the density contrast are in good agreement with numerical calculations, in the non linear regime are more accurate than the results obtained using linear perturbation theory, and are also more accurate than the formulae in terms of the curvature function.

Renormalization Group Method Applied to Kinetic Equations: roles of initial values and time

description: The so-called renormalization group (RG) method is applied to derive kinetic and transport equations from the respective microscopic equations. The derived equations include Boltzmann equation in classical mechanics, Fokker-Planck equation, a rate equation in a quantum field theoretical model. Utilizing the formulation of the RG method which elucidates the important role played by the choice of the initial conditions, the general structure and the underlying assumptions in the derivation of kinetic equations in the RG method is clarified. It is shown that the present formulation naturally leads to the choice for the initial value of the microscopic distribution function at arbitrary time $t_0$ to be on the averaged distribution function to be determined. The averaged distribution function may be thought as an integral constant of the solution of microscopic evolution equation; the RG equation gives the slow dynamics of the would-be initial constant, which is actually the kinetic equation governing the averaged distribution function. It is further shown that the averaging as given above gives rise to a coarse-graining of the time-derivative which is expressed with the initial time $t_0$, thereby leads to time-irreversible equations even from a time-reversible equation. It is shown that a further reduction of Boltzmann equation to fluid dynamical equations and the adiabatic elimination of fast variables in Fokker-Planck equation are also performed in a unified way in the present method.

description: Motivated by results from an earlier Brownian Dynamics (BD) simulation for the collapse of a single, stiff polymer in a poor solvent [B. Schnurr, F. C. MacKintosh, and D. R. M. Williams, Europhys. Lett. 51 (3), 279 (2000)] we calculate the conformational energies of the intermediate (racquet) states suggested by the simulations. In the absence of thermal fluctuations (at zero temperature) the annealed shapes of these intermediates are well-defined in certain limits, with their major structural elements given by a particular case of Euler's elastica. In appropriate units, a diagram emerges which displays the relative stability of all states, tori and racquets. We conclude that, in marked contrast to the collapse of flexible polymers, the condensation of semiflexible or stiff polymers generically proceeds via a cascade through metastable intermediates, the racquets, towards a ground state, the torus or ring, as seen in the dynamical simulations.

The method is based on the experimental investigation of vertical oscillations of a single particle in the sheath of a low-pressure radio-frequency discharge. It is shown that the oscillations become strongly nonlinear and secondary harmonics are generated as the amplitude increases. The theory of anharmonic oscillations provides a good qualitative description of the data and gives estimates for the first two anharmonic terms in an expansion of the sheath potential around the particle equilibrium.

description: Using structural equation models and data from three provinces in the Democratic Republic of Congo, we assess the factors affecting external linkages among rural producer organizations and determinants of performance in agricultural service provision in a post-conflict setting. Environmental risks, membership in umbrella organizations, external assistance during set-up, and membership size are significant factors affecting external linkages. Measures of external linkages, members’ financial contributions, management capacity, formal governance systems, and incidence of conflict events are statistically significant factors influencing performance. Results highlight the role of enabling environment for these grassroot organizations to thrive and benefit their communities.

description: To date there is limited knowledge on the role that post-harvest storage protectants, chemical or otherwise, play in a smallholder farmer’s decision to adopt of high-yielding improved maize varieties. This is a key issue because higher yielding varieties are often more susceptible to storage pests than lower yielding traditional varieties. We present novel evidence from Malawi which shows that access to storage chemicals has a positive and significant effect on both farmer adoption of improved seed and the area that households plant to improved maize. Results have important implications for input support programs because failing to account for small holder storage challenges may reduce a farmer’s incentive to adopt modern seed varieties that can enhance staple crop production and food security.

description: To make complementary GaN electronics more than a pipe dream, it is essential to understand the low mobility of 2D hole gases in III-Nitride heterostructures. This work derives both the acoustic and optical phonon spectra present in one of the most prominent p-channel heterostructures (the all-binary GaN/AlN stack) and computes the interactions of these spectra with the 2D hole gas, capturing the temperature dependence of its intrinsic mobility. Finally, the effects of strain on the electronic structure of the confined 2D hole gas are examined and a means is proposed to engineer the strain to improve the 2D hole mobility for enhanced p-channel device performance, with the goal of enabling wide-bandgap CMOS.

description: We present a generalisation of efficient numerical frameworks for modelling fluid-filament interactions via the discretisation of a recently-developed, non-local integral equation formulation to incorporate regularised Stokeslets with half-space boundary conditions, as motivated by the importance of confining geometries in many applications. We proceed to utilise this framework to examine the drag on slender inextensible filaments moving near a boundary, firstly with a relatively-simple example, evaluating the accuracy of resistive force theories near boundaries using regularised Stokeslet segments. This highlights that resistive force theories do not accurately quantify filament dynamics in a range of circumstances, even with analytical corrections for the boundary. However, there is the notable and important exception of movement in a plane parallel to the boundary, where accuracy is maintained. In particular, this justifies the judicious use of resistive force theories in examining the mechanics of filaments and monoflagellate microswimmers with planar flagellar patterns moving parallel to boundaries. We proceed to apply the numerical framework developed here to consider how filament elastohydrodynamics can impact drag near a boundary, analysing in detail the complex responses of a passive cantilevered filament to an oscillatory flow. In particular, we document the emergence of an asymmetric periodic beating in passive filaments in particular parameter regimes, which are remarkably similar to the power and reverse strokes exhibited by motile 9+2 cilia. Furthermore, these changes in the morphology of the filament beating, arising from the fluid-structure interactions, also induce a significant increase in the hydrodynamic drag of the filament.

description: The stability of physical systems depends on the existence of a state of least energy. In gravity, this is guaranteed by the positive energy theorem. For topological reasons this fails for nonsupersymmetric Kaluza-Klein compactifications, which can decay to arbitrarily negative energy. For related reasons, this also fails for the AdS soliton, a globally static, asymptotically toroidal $Λ<0$ spacetime with negative mass. Nonetheless, arguing from the AdS/CFT correspondence, Horowitz and Myers (hep-th/9808079) proposed a new positive energy conjecture, which asserts that the AdS soliton is the unique state of least energy in its asymptotic class. We give a new structure theorem for static $Λ<0$ spacetimes and use it to prove uniqueness of the AdS soliton. Our results offer significant support for the new positive energy conjecture and add to the body of rigorous results inspired by the AdS/CFT correspondence.

description: In this work, we study the wave equations in 2D Euclidian space for a new non-central potential consisting of a Kratzer term and a dipole term. For Schrodinger equation, we obtain the analytical expressions of the energies and the wave functions of the system. For Klein-Gordon and Dirac equations, we do the study in both spin and pseudo-spin symmetries to get the eigenfunctions and the eingenvalues. Then we study the dependence of energies on the radial moment D_{r} and the angular moment D_{theta}. We find that the D_{theta} term tends to dissociate the system, and thus counteracts the Coulomb binding effect, and that the D_{r} term can either amplify or decrease this effect according to its sign.

description: Magnetic skyrmions are particle-like topological excitations that recently generated much interest as candidates for future spintronic devices based on skyrmion small size, enhanced topological stability, and/or mutual interaction. Here we examine the properties of isolated skyrmions in a frustrated chiral magnet with competing Dzyaloshinskii-Moriya and frustrated exchange interactions. We show that the skyrmion size drastically decreases even for small values of competing stabilization mechanisms. Skyrmion mutual interaction remains attracting as is inherent for frustrated skyrmions, but the value of the Dzyaloshinskii constant regulates the number of minima in the interaction potentials. Moreover, the constructed phase diagrams for a chiral helimagnet contain a distorted spiral state that can be considered as a buffer between the helicoidal and conical one-dimensional modulations. The formulated concepts may further enhance the functionalities of spintronic devices. In particular, the controlled instability of skyrmions with respect to the conical state allows to obtain bimeron-like structures. Moreover, our results provide physical insight into the chiral states in the magnetic systems, e.g., in MnSi$_{1-x}$Ge$_x$.

description: The MadGraph5 aMC@NLO framework aims to automate all types of leading- and next-to-leading-order-accurate simulations for any user-defined model that stems from a renormalisable Lagrangian. In this paper, we present all of the key ingredients of such models in the context of supersymmetric theories. In order to do so, we extend the FeynRules package by giving it the possibility of dealing with different renormalisation options that are relevant to supersymmetric models. We also show how to deal with the problem posed by the presence of narrow resonances, thus generalising the so-called on-shell subtraction approaches. We extensively compare our total rate results with those of both Prospino2 and Resummino, and present illustrative applications relevant to the 13 TeV LHC, both at the total-rate and differential levels. The computer programs that we have used to obtain the predictions presented here are all publicly available.

description: In the literature, the effect of contract farming on the productivity efficiency or profitability is rarely studied, especially in the crop sector. In this paper, we use a farm-level dataset (Agriculture and Resource Management Survey) to examine the effect of contract farming on the farmers' average return for the corn, soybean and wheat producers. The results of the matching estimation show that without matching, the effect of contract farming on the average returns of the corn and soybean producers might be underestimated, and contract farming might have a negligible (statistically insignificant) effect on the average return of the wheat producer.
On the Relation Between Unit Testing and Code Quality

description: Unit testing has been considered as having a key role in building high quality software, and therefore it has been widely used in practice. However, data on the relationship between unit testing and aspects of software quality remain scarce. A survey study with 235 survey responses from seven organizations was conducted in order to understand the correlation between practitioners' perception of code quality and unit testing practices. In addition, we conducted a case study in one of these organizations to investigate the correlation between unit test coverage and post-unit test defects. In both cases none or weak correlations were found. We recommend further research on the effectiveness of different testing practices in order to help practitioners to understand how to best allocate their resources to the testing chain.

description: A computer simulation model is used to study the density profile and flow of a miscible gaseous fluid mixture consisting of differing constituent masses ($m_A = m_B/3$) through an open matrix. The density profile is found to decay with the height $\propto \exp(-m_{A(B)}h)$, consistent with the barometric height law. The flux density shows a power-law increase $\propto {(p_c-p)}^μ$ with $μ\simeq 2.3$ at the porosity $1-p$ above the pore percolation threshold $1-p_c$

Land Economics/Use

description: We evaluate how land use change and the value ecosystem services affect the decision to invest in public land acquisitions. Our application is for the state of Minnesota, and we consider the acquisitions by Department of Natural Resources over the last two decades. We calculate a return on investment (ROI) in conservation showing the increase in the value of ecosystem goods and services from public lands per dollar spent on acquisition. A spatially-explicit modeling tool, the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST), quantifies how changes in land use and land cover (LULC) influence the provision and value of a suite of ecosystem services: carbon sequestration, timber production, water quality, habitat quality, and outdoor recreation. The present value of the difference in the value of ecosystem services from landscapes with and without acquisitions in 1992 and for the econometrically modeled future landscapes in 2022 and 2052 is the return from the investment in the acquisitions. We find a limited number of acquisitions have a ROI above one. Also, we observe the estimated return in the acquisitions is much more influenced by the economic value of ecosystem services than the projected development threat to the acquisitions.

description: This article reviews the current literature on USDA farm-level data reports and looks at the impact of information contained in the USDA Crop Production report on U.S., Iowa, Illinois, Nebraska, North Carolina, and Wisconsin corn prices. A hypothesis is tested concerning the significance of the reaction to the corn basis from the report. The hypothesis is tested using maximum-likelihood parameter estimates of the effect of stocks data, previous year's production number, and separate dummy variables for the August, September, October, and November release of the USDA Crop Production report on the absolute percent change of the corn basis from the month before the report is released to the month in which the report is released. Evidence is found that supports the hypothesis that USDA reports significantly affect the corn market at the national level and in Illinois, Iowa, and Nebraska. August and October are found to be the most significant month for market reactions to the report for the states affected. No evidence is found of a price reaction in the North Carolina and Wisconsin corn markets. The study period is 1949-2011.
Elastic turbulence in a polymer solution flow

description: Turbulence is one of the most fascinating phenomena in nature and one of the biggest challenges for modern physics. It is common knowledge that a flow of a simple, Newtonian fluid is likely to be turbulent, when velocity is high, viscosity is low and size of the tank is large\cite{Landau,Tritt}. Solutions of flexible long-chain polymers are known as visco-elastic fluids\cite{bird}. In our experiments we show, that flow of a polymer solution with large enough elasticity can become quite irregular even at low velocity, high viscosity and in a small tank. The fluid motion is excited in a broad range of spatial and temporal scales. The flow resistance increases by a factor of about twenty. So, while the Reynolds number, $\boldmath{Re}$, may be arbitrary low, the observed flow has all main features of developed turbulence, and can be compared to turbulent flow in a pipe at $\bf {Re\simeq 10^5}$\cite{Landau,Tritt}. This {\it elastic turbulence} is accompanied by significant stretching of the polymer molecules, and the resulting increase of the elastic stresses can reach two orders of magnitude.

description: We consider an expanding flow of smooth, closed, uniformly convex hypersurfaces in (n+1)-dimensional Euclidean space with speed fu^{alpha}{sigma}_k^{beta}, where u is the support function of the hypersurface, alpha, beta are two constants, and beta>0, sigma_k is the k-th symmetric polynomial of the principle curvature radii of the hypersurface, k is an integer and 1<= k<= n. We prove that the flow has a unique smooth and uniformly convex solution for all time, and converges smoothly after normalisation, to a soliton which is a solution of a elliptic equation, when the constants alpha, beta belong to a suitable range, and the function f satisfies a strictly spherical convexity condition. When beta=1, the soliton equation is just the equation of Lp Christoffel-Minkowski problem. Thus our argument provides a proof to the well-known L_p Christoffel-Minkowski problem for the case p>= k+1 where p=2-alpha, which is identify with Ivaki's recent result.

description: We study possible effects of CP violation in the Higgs sector on $t\bar t$ production at a $γγ$-collider. These studies are performed in a model-independent way in terms of six form-factors $\{\Re(S_γ), \Im(S_γ), \Re(P_γ), \Im(P_γ), S_t, P_t\}$ which parametrize the CP mixing in the Higgs sector, and a strategy for their determination is developed. We observe that the angular distribution of the decay lepton from $t/\bar t$ produced in this process is independent of any CP violation in the $tbW$ vertex and hence best suited for studying CP mixing in the Higgs sector. Analytical expressions are obtained for the angular distribution of leptons in the c.m. frame of the two colliding photons for a general polarization state of the incoming photons. We construct combined asymmetries in the initial state lepton (photon) polarization and the final state lepton charge. They involve CP even ($x$'s) and odd ($y$'s) combinations of the mixing parameters. We study limits up to which the values of $x$ and $y$, with only two of them allowed to vary at a time, can be probed by measurements of these asymmetries, using circularly polarized photons. We use the numerical values of the asymmetries predicted by various models to discriminate among them. We show that this method can be sensitive to the loop-induced CP violation in the Higgs sector in the MSSM.
