description: This paper can only sketch some of the important research challenges in Agricultural Economics and the development of analytical approaches to the solution of these problems. The four volume Survey of Agricultural Economics Literature covers in detail the period from 1940 to 1980. The approach here is to distill from the Journal some of the major problems facing agriculture and rural America, and to present illustrations of the research response that led to the development of our present analytical and quantitative methods. Historically, agricultural economists have been problem—oriented. Contributions to theory and quantitative methods have come through attempts to get analytical or quantitative answers to important problems facing the economy. I trust this emphasis will continue, although one can sense the growing use of complicated theoretical constructs that cannot as yet be quantified. One can see the attraction of such efforts when faced with the grim realities of modeling with poor data sets!

description: We show that configuration space techniques can be used to efficiently calculate the complete Laurent series \eps-expansion of sunrise-type diagrams to any loop order in D-dimensional space-time for any external momentum and for arbitrary mass configurations. For negative powers of \eps the results are obtained in analytical form. For positive powers of \eps including the finite \eps^0 contribution the result is obtained numerically in terms of low-dimensional integrals. We present general features of the calculation and provide exemplary results up to five loop order which are compared to available results in the literature.

description: The present chapter reviews current neutron and x-ray scattering techniques employed to elucidate the magnetic structures and spin dynamics of magnetic materials. Both techniques provide measurements as a function of the energy and the momentum transferred from the spin system to the probe particles, in terms of five-dimensional data sets as a function of various thermodynamic fields at the control of the experimenter. These scattering techniques yield fundamental information about the equal-time correlations such the magnetic configuration and symmetry, as well as the dynamics that determine the exchange interactions for prototypical systems that behave as linear, planar, or three-dimensional systems. Historically, neutron scattering has been the magnetic scattering technique of choice for such investigations, but the extraordinary advances in resonant x-ray scattering techniques have enable new types of magnetic scattering measurements. The type of information obtained with the two techniques is largely complementary and depends on the interests of the investigators. We discuss these possibilities and provide numerous examples of the techniques applied to different classes of magnetic systems.

title: Haageocereus: Taxonomy for the Conservation of the Genus in Peru.
Creators: name: Moya-Mendez, Natalia Calderon
Publisher: name: The Open University
Year: 2006

description: The genus Haageocereus (Cactaceae) is mostly endemic o f Peru, occupying arid areas draining westwards o f Andes. In Peru, Haageocereus is found between 50 to 2800 m, from 79°54’W, 5°7’S (dept. Piura) to 70°52’W, 18°0’S (dept. Tacna).

 The understanding of this genus has been limited by several nomenclature problems such as multiple descriptions for relatively few species, and most of the types are very poor or absent, and cases of misapplication of names also exist. In terms of conservation, speed of habitat loss is worrying for most of the environments where Haageocereus occurs, especially because there are very few populations included in national protected areas.

 Extensive fieldwork, morphological studies, literature revision and study of types led to the delimitation of 9 species and 6 heterotypic subspecies recognized in this work. Descriptions and keys are accompanied by line drawings, photos and distribution maps. SEM photos were also produced for almost every taxon. Exsiccata prepared during this study constitute approximately the 79.2% of existing Haageocereus herbarium samples from wild origin.

 Conservation assessments based on the Red List IUCN categories (2001) determined 3 taxa as Critically Endangered, 8 taxa as Endangered and 5 taxa as Vulnerable in Peru. Five different types of habitat for Haageocereus have been identified, described and correlated to different kinds of threats in order to present a list of proposed protected areas and recommendations for the conservation of these taxa.

Habiro originally derived these formulas using the quantum group U_q sl_2. As an application, we give a formula for the colored Jones polynomial of twist knots, generalizing formulas of Habiro and Le for the trefoil and the figure eight knot.

description: The research was focused on the research training in undergraduate at the Sociocultural Studies Program at University of Pinar del Río "Hermanos Saíz Montes de Oca". The objective was to propose a pedagogical conception about this process, taking in to account the sociocultural management as holistic professional performance. For the study, we used methods like historic, document analyzes, scientific observation, survey and interview. In the results, we propose the research skills, ethical values and knowledge tha allow optimizing the vocational training. Finally, we conclude that it is necessary to introduce in the curriculum the sociocultural research contents as a transversal axis.

The large index contrast induces strong longitudinal electric field components that play an important role in the nonlinear conversion. We show that many different waveguide dimensions are suitable for efficient conversion of a fundamental quasi-TE pump mode around the 1550 nm telecommunication wavelength to a higher-order second harmonic mode.

Prospects for Detecting a Neutrino Magnetic Moment with a Tritium Source and Beta-beams

description: We compare the prospects for detecting a neutrino magnetic moment by the measurement of neutrinos from a tritium source, reactors and low-energy beta-beams. In all cases the neutrinos or antineutrinos are detected by scattering of electrons. We find that a large (20 MCurie) tritium source could improve the limit on the neutrino magnetic moment significantly, down to the level of a few $\times 10^{-12}$ while low-energy beta-beams with sufficiently rapid production of ions could improve the limits to the level of a few $\times 10^{-11}$. The latter would require ion production at the rate of at least $10^{15}$ s$^{-1}$.

description: The thermodynamics of strongly anisotropic crystalline surfaces is analogous to that of a binary mixture exhibiting phase separation. On a metastable planar surface, formation of stable orientations requires a nucleation process, in which the energy associated with the presence of corners must be considered. In this context, a nucleation event corresponds to the formation of a critical shape for the crystalline surface before the system enters the growth regime. We first derive the Euler-Lagrange equation for crystal surface nucleation, in two dimensions, and show that the saddle-point condition corresponds to a vanishing chemical potential along this critical surface. We then perform numerical simulation of the equation of motion for the crystal surface and show that, as compared with saddle point nucleation, ridge crossing is dynamically favoured.

description: Generalized synchronization of chaos is a type of cooperative behavior in directionally-coupled oscillators that is characterized by existence of stable and persistent functional dependence of response trajectories from the chaotic trajectory of driving oscillator. In many practical cases this function is non-differentiable and has a very complex shape. The generalized synchrony in such cases seems to be undetectable, and only the cases, in which a differentiable synchronization function exists, are considered to make sense in practice. We show that this viewpoint is not always correct and the non-differentiable generalized synchrony can be revealed in many practical cases. Conditions for detection of generalized synchrony are derived analytically, and illustrated numerically with a simple example of non-differentiable generalized synchronization.

description: Ultra-short period (USP) planets are a class of exoplanets with periods shorter than one day. The origin of this sub-population of planets is still unclear, with different formation scenarios highly dependent on the composition of the USP planets. A better understanding of this class of exoplanets will, therefore, require an increase in the sample of such planets that have accurate and precise masses and radii, which also includes estimates of the level of irradiation and information about possible companions. Here we report a detailed characterization of a USP planet around the solar-type star HD 80653 $\equiv$ EP 251279430 using the K2 light curve and 108 precise radial velocities obtained with the HARPS-N spectrograph, installed on the Telescopio Nazionale Galileo. From the K2 C16 data, we found one super-Earth planet ($R_{b}=1.613\pm0.071 R_{\oplus}$) transiting the star on a short-period orbit ($P_{\rm b}=0.719573\pm0.000021$ d). From our radial velocity measurements, we constrained the mass of HD 80653 b to $M_{b}=5.60\pm0.43 M_{\oplus}$. We also detected a clear long-term trend in the radial velocity data. We derived the fundamental stellar parameters and determined a radius of $R_{\star}=1.22\pm0.01 R_{\odot}$ and mass of $M_{\star}=1.18\pm0.04 M_{\odot}$, suggesting that HD 80653, has an age of $2.7\pm1.2$ Gyr. The bulk density ($ρ_{b} = 7.4 \pm 1.1$ g cm$^{-3}$) of the planet is consistent with an Earth-like composition of rock and iron with no thick atmosphere. Our analysis of the K2 photometry also suggests hints of a shallow secondary eclipse with a depth of 8.1$\pm$3.7 ppm. Flux variations along the orbital phase are consistent with zero. The most important contribution might come from the day-side thermal emission from the surface of the planet at $T\sim3480$ K.

description: Organisms have evolved sensory mechanisms to extract pertinent information from their environment, enabling them to assess their situation and act accordingly. For social organisms travelling in groups, like the fish in a school or the birds in a flock, sharing information can further improve their situational awareness and reaction times. Data on the benefits and costs of social coordination, however, have largely allowed our understanding of why collective behaviours have evolved to outpace our mechanistic knowledge of how they arise. Recent studies have begun to correct this imbalance through fine-scale analyses of group movement data. One approach that has received renewed attention is the use of information theoretic (IT) tools like mutual information, transfer entropy and causation entropy, which can help identify causal interactions in the type of complex, dynamical patterns often on display when organisms act collectively. Yet, there is a communications gap between studies focused on the ecological constraints and solutions of collective action with those demonstrating the promise of IT tools in this arena. We attempt to bridge this divide through a series of ecologically motivated examples designed to illustrate the benefits and challenges of using IT tools to extract deeper insights into the interaction patterns governing group-level dynamics. We summarize some of the approaches taken thus far to circumvent existing challenges in this area and we conclude with an optimistic, yet cautionary perspective.

description: DDue to new technologies, providers of digital goods and services collect an ever-increasing amount of personal data. Although the GDPR mandates that providers must inform their customers about the handling of their data, past privacy scandals have shown that customers lack information. In this study, we adopt a qualitative-exploratory approach to develop a rich understanding of the practices about which customers are not fully informed. We rely on agency theory to understand hidden actions as an informational advantage of providers. By conducting focus groups, we identify perceptions of three key hidden actions of smart product customers in B2C service ecosystems. Building on the hidden actions, we understand the relationship between customer and provider in smart service ecosystems characterized by information asymmetries. With our research, we provide the first steps towards understanding the nature and role of hidden actions in the context of smart service ecosystems. For practitioners, we provide guidance on how to effectively reduce information asymmetries.

description: We present spectropolarimetric observations of the FK Com star HD 199178 obtained between 1998 December and 2003 August at the Telescope Bernard Lyot (Observatoire du Pic du Midi, France). We report the detection of a photospheric magnetic field and reconstruct its distribution by means of Zeeman-Doppler Imaging. We observe large regions where the magnetic field is mainly azimuthal, suggesting that the dynamo processes generating the magnetic activity of HD 199178 may be active very close to the stellar surface. We investigate the rapid evolution of surface brightness and magnetic structures from a continuous monitoring of the star over several weeks in 2002 and 2003. We report that significant changes occur in the distribution of cool spots and magnetic regions on typical timescales of the order of 2 weeks. Our spectropolarimetric observations also suggest that the surface of HD 199178 is sheared by differential rotation, with a difference in rotation rate between equatorial and polar regions of the order of 1.5 times that of the Sun.

description: Optical frequency combs are revolutionising modern time and frequency metrology. In the past years, their range of applications has increased substantially, driven by their miniaturisation through microresonator-based solutions. The combs in such devices are typically generated using the third-order $χ^{(3)}$-nonlinearity of the resonator material. An alternative approach is making use of second-order $χ^{(2)}$-nonlinearities. While the idea of generating combs this way has been around for almost two decades, so far only few demonstrations are known, based either on bulky bow-tie cavities or on relatively low-$Q$ waveguide resonators. Here, we present the first such comb that is based on a millimetre-sized microresonator made of lithium niobate, that allows for cascaded second-order nonlinearities. This proof-of-concept device comes already with pump thresholds as small as 2 mW, generating repetition-rate-locked combs around 1064 nm and 532 nm. From the nonlinear dynamics point of view, the observed combs correspond to the Turing roll patterns.

description: 1T-TiSe2 is one of the most studied charge density wave (CDW) systems, not only because of its peculiar properties related to the CDW transition, but also due to its status as a promising candidate of exciton insulator signaled by the proposed plasmon softening at the CDW wave vector. Using high-resolution electron energy loss spectroscopy, we report a systematic study of the temperature-dependent plasmon behaviors of 1T-TiSe2. We unambiguously resolve the plasmon from phonon modes, revealing the existence of Landau damping to the plasmon at finite momentums, which does not support the plasmon softening picture for exciton condensation. Moreover, we discover that the plasmon lifetime at zero momentum responds dramatically to the bandgap evolution associated with the CDW transition. The interband transitions near the Fermi energy in the normal phase is demonstrated serving as a strong damping channel of plasmons, while such a channel in the CDW phase is suppressed due to the CDW gap opening, which results in the dramatic tunability of the plasmon in semimetals or small-gap semiconductors.

description: We study dynamical self-localization of gauge theories in higher dimensions. Specifically, we consider a 5D $U(1)$ gauge theory in the linear dilaton (clockwork) background, with anisotropic gauge couplings along the transverse (fifth) direction and the longitudinal (four-dimensional) directions. By using lattice techniques, we calculate the space plaquettes and the helicity moduli and we determine the phase diagram of the model. We find strong evidence that the model exhibits a new phase, a layer phase, where the four-dimensional physics decouples from the five-dimensional dynamics. The layer phase corresponds to a strong force along the fifth direction and a Coulomb phase along the four-dimensional longitudinal directions. This is in accordance with the clockwork mechanism where light particles with exponentially suppressed interactions are generated in theories with no fundamental small parameters.

description: The cosmological lithium problem, that is, the discrepancy between the lithium abundance predicted by the Big Bang nucleosynthesis and the one observed for the stars of the 'Spite plateau', is one of the long standing problems of modern astrophysics. Recent hints for a possible solution involve lithium burning induced by protostellar mass accretion on Spite plateau stars. The purpose of this paper is to analyze the effect of protostellar accretion on low metallicity low-mass stars with a focus on PMS lithium evolution. We computed the evolution from the protostar to the MS phase of accreting models with final masses of 0.7 and 0.8 M$_\odot$, and three metallicities Z=0.0001, Z=0.0010, and Z=0.0050. The effects of changing the main parameters affecting accreting models, that is the accretion energy (cold versus hot accretion), the initial seed mass $M_{seed}$ and radius $R_{seed}$, and the mass accretion rate $\dot{m}$, have been investigated in detail. As for the main stellar properties and the surface $^7 Li$ abundance, hot accretion models converge to standard non-accreting ones within 1 Myr, regardless of the actual value of $M_{seed}$, $R_{seed}$, and $\dot{m}$. Also, cold accretion models with a relatively large $M_{seed}$ ($\gtrsim 10~M_{jup}$) or $R_{seed}$ ($\gtrsim 1~R_\odot$) converge to standard non-accreting ones in less than about 10-20~Myr. A drastically different evolution occurs whenever a cold protostellar accretion process starts from small values of $M_{seed}$ and $R_{seed}$ ($M_{seed}\sim 1~M_{jup}$, $R_{seed} \lesssim 1~R_\odot$). These models almost entirely skip the standard Hayashi track evolution and deplete Li before the end of the accretion phase. The exact amount of depletion depends on the actual combination of the accretion parameters ($\dot{m}$, $M_{seed}$, and $R_{seed}$), achieving in some cases the complete exhaustion of Li in the whole star.

description: We present a realization of quantized charge pumping. A lateral quantum dot is defined by metallic split gates in a GaAs/AlGaAs heterostructure. A surface acoustic wave whose wavelength is twice the dot length is used to pump single electrons through the dot at a frequency f=3GHz. The pumped current shows a regular pattern of quantization at values I=nef over a range of gate voltage and wave amplitude settings. The observed values of n, the number of electrons transported per wave cycle, are determined by the number of electronic states in the quantum dot brought into resonance with the fermi level of the electron reservoirs during the pumping cycle.

description: When data on treatment assignment, outcomes, and covariates from a randomized trial are available, a question of interest is to what extent covariates can be used to optimize treatment decisions. Statistical hypothesis testing of covariate-by-treatment interaction is ill-suited for this purpose. The application of decision theory results in treatment rules that compare the expected benefit of treatment given the patient's covariates against a treatment threshold. However, determining treatment threshold is often context-specific, and any given threshold might seem arbitrary when the overall capacity towards predicting treatment benefit is of concern. We propose the Concentration of Benefit index (Cb), a threshold-free metric that quantifies the combined performance of covariates towards finding individuals who will benefit the most from treatment. The construct of the proposed index is comparing expected treatment outcomes with and without knowledge of covariates when one of a two randomly selected patients are to be treated. We show that the resulting index can also be expressed in terms of the integrated efficiency of individualized treatment decision over the entire range of treatment thresholds. We propose parametric and semi-parametric estimators, the latter being suitable for out-of-sample validation and correction for optimism. We used data from a clinical trial to demonstrate the calculations in a step-by-step fashion, and have provided the R code for implementation (https://github.com/msadatsafavi/txBenefit). The proposed index has intuitive and theoretically sound interpretation and can be estimated with relative ease for a wide class of regression models. Beyond the conceptual developments, various aspects of estimation and inference for such a metric need to be pursued in future research.

1982 Food Price Update

Year: 1982
Subjects: Food Consumption/Nutrition/Food Safety

description: Retail food prices this year are expected to average 5 to 6 percent higher than last year's prices. This would be below 1981 's price increase of 7 .9 percent, and would continue a slowdown of annual food price increases that began in 1980. Also, 1982 could be the fourth consecutive year that food prices rise less than nonfood prices. As in 1981, higher food marketing costs will be the major contributor to the food price increase. However, because of the recession and the lower general inflation rate, marketing costs may rise less than they have in recent years. The farm-to-retail price spread, expected to increase 6 to 7 percent above the 1981 spread, may cause about two-thirds of the retail food price increase. The farm value of foods is expected to be up 2 to 4 percent, contributing about one sixth of the food price rise. The balance of the food price increase will reflect an expected 4- to 6-percent increase in retail prices for imported foods and fish.

description: We demonstrate the possibility of a good description of the processes $ϕ(1020)\to γππ$ and $ϕ(1020)\to γf_0(980)$ within the framework of non-relativistic quark model assuming $f_0(980)$ to be dominantly quark--antiquark system. Different mechanisms of the radiative decay, that is, the emission of photon by the constituent quark (additive quark model) and charge-exchange current, are considered. We also discuss the status of the threshold theorem applied to the studied reactions, namely, the behaviour of the decay amplitude at $M_{ππ} \to m_ϕ$ and $m_{f_0}\to m_ϕ$. In conclusion the arguments favouring the $q\bar q$ origin of $f_0(980)$ are listed.
