description: Sustainable development is an important part of school curricula and standards, particularly in agricultural education. However, the teaching and education devoted to it all too often boils down to a collection of information or to behaviours to follow. However, it is both more conceptual and more practical teaching that can give young people sufficient reflexivity on human practices and activities to consider them from a sustainability perspective. We formalize and test the richness of the notion of "conceptual field" to consider how it can meet the objectives of forming judgement and empowering learners in terms of sustainability.
description: Le développement durable est très présent dans les référentiels et les curricula scolaires, en particulier dans l’enseignement agricole. Pourtant, l’enseignement et l'éducation qui lui sont consacrés se résument trop souvent à un ensemble d’informations ou à des comportements à suivre. Or, c’est un enseignement tout à la fois plus conceptuel et plus pratique qui peut donner aux jeunes suffisamment de réflexivité sur les pratiques et les activités humaines afin de les envisager dans une perspective de durabilité. Nous formalisons et mettons ici à l’épreuve la richesse de la notion de "champ conceptuel" pour envisager en quoi celle-ci peut répondre aux objectifs de former au jugement et donner du pouvoir d’agir aux apprenants en termes de durabilité.

description: Food security extends beyond a population’s immediate nutritional intake. It is not only an essential pillar of the nation concept, but has far-reaching implications that extend beyond national borders in today’s globalized trading of agricultural commodities. The Global Hunger Index (GHI), an established metric for measuring food insecurity in developing countries, can be used to measure the overall impact of agricultural economic policies. Multiple regression and ANOVA tests were implemented to examine the significance a range of predictors had on determining GHI in India, Nigeria, and Brazil. Each country has a major impact on food security for their region, along with global economic policies. The predictors encompass a variety of factors including basic, political, economic, and infrastructural needs. The data for the research was acquired from The Food Agricultural Organization Food Security Report and the International Food Policy Research Institute for 1995-2011. The study finds that the GHI in India and Nigeria was significantly affected by gross domestic product per capita (GDPC) and water access, while only water was significant in determining Brazil’s GHI. With this research as a template, policy makers can better tailor aide programs to optimize the global decrease of the GHI and improve global food security.

description: Concerns about the general state of the environment have spurred growing consumer demands for food products that have sustainability attributes including information on the environmental impact of production processes. For New Zealand, assessing the role of the ‘Clean-Green’ brand in export market consumers purchase decisions is of crucial strategic importance. In a series of choice experiments concerning lamb and dairy product purchase decisions, this study estimates willingness to pay for environmental sustainability attributes in India and China alongside animal welfare and food safety. The research design identifies if values differ according to the country of origin. Results indicate that environmental sustainability attributes significantly influence consumers’ purchase decisions; however food safety and farm animal welfare are found to be valued more by both Indian and Chinese consumers. Respondents are more likely to purchase lamb and dairy products from New Zealand that have production processes enhancing biodiversity and minimising water pollution. These results support primary sector initiatives to improve environmental performance and aid stakeholders in identifying which elements of the ‘Clean-Green’ brand influence product choice.

description: This paper surveys the existing literature on diffusion of environmentally beneficial technology. Overall, it confirms many of the lessons of the larger literature on technology diffusion: diffusion often appears slow when viewed from the outside; the flow of information is an important factor in the diffusion process; networks and organisations can matter; behavioural factors such as values and cognitive biases also play a role. With respect to policy instruments, there is some evidence that the flexibility of market-based instruments can have a beneficial impact on technology diffusion, but there are also numerous cases in which regulations have forced the adoption of new technologies. There would be significant benefit to increased investment in studies that look at questions such as the role of information provision, networks and framing issues in households’ and firms’ adoption decisions.
Information Extraction Tool Text2ALM: From Narratives to Action Language System Descriptions

description: In this work we design a narrative understanding tool Text2ALM. This tool uses an action language ALM to perform inferences on complex interactions of events described in narratives. The methodology used to implement the Text2ALM system was originally outlined by Lierler, Inclezan, and Gelfond (2017) via a manual process of converting a narrative to an ALM model. It relies on a conglomeration of resources and techniques from two distinct fields of artificial intelligence, namely, natural language processing and knowledge representation and reasoning. The effectiveness of system Text2ALM is measured by its ability to correctly answer questions from the bAbI tasks published by Facebook Research in 2015. This tool matched or exceeded the performance of state-of-the-art machine learning methods in six of the seven tested tasks. We also illustrate that the Text2ALM approach generalizes to a broader spectrum of narratives.

description: We show that B-model topological strings on local Calabi-Yau threefolds are large N duals of matrix models, which in the planar limit naturally give rise to special geometry. These matrix models directly compute F-terms in an associated N=1 supersymmetric gauge theory, obtained by deforming N=2 theories by a superpotential term that can be directly identified with the potential of the matrix model. Moreover by tuning some of the parameters of the geometry in a double scaling limit we recover (p,q) conformal minimal models coupled to 2d gravity, thereby relating non-critical string theories to type II superstrings on Calabi-Yau backgrounds.

description: We employ the Dynamical Cluster Approximation (DCA) in conjunction with the Fluctuation Exchange Approximation (FLEX) to study the Hubbard model. The DCA is a technique to systematically restore the momentum conservation at the internal vertices of Feynman diagrams relinquished in the Dynamical Mean Field Approximation (DMFA). FLEX is a perturbative diagrammatic approach in which classes of Feynman diagrams are summed over analytically using geometric series. The FLEX is used as a tool to investigate the complementarity of the DCA and the finite size lattice technique with periodic boundary conditions by comparing their results for the Hubbard model. We also study the microscopic theory underlying the DCA in terms of compact (skeletal) and non-compact diagrammatic contributions to the thermodynamic potential independent of a specific model. The significant advantages of the DCA implementation in momentum space suggests the development of the same formalism for the frequency space. However, we show that such a formalism for the Matsubara frequencies at finite temperatures leads to acausal results and is not viable. However, a real frequency approach is shown to be feasible.

description: This article assesses the political economy of the 2014 farm bill, which eliminated annual fixed direct payments but offers enhanced downside risk protection against low prices or declining revenue. The farm bill secured substantial bipartisan majorities in a politically contentious Congress. The countercyclical structure of U.S. support is reaffirmed and crop insurance is enhanced as a safety net pillar. Open policy issues include the distribution of benefits among crops, the design of multiple year support around moving-average revenue benchmarks versus fixed references prices, and questions related to crop insurance, including the overall level of premium subsidies. In an international context, we conclude the 2014 farm safety net likely would not have been enacted had multilateral agreement been reached on the 2008 Doha Round negotiating documents; conversely, the 2014 farm bill makes achieving those limits more difficult.

description: The steady flow of spherical particles in a rectangular bin is studied using the Discrete Element Method (DEM) for different flow rates of the particles from the bin, in the slow flow regime. The flow has two non-zero velocity components and is more complex than the widely studied unidirectional shear flows. The objective of the study is to characterize, in detail, the local rheology of the flowing material. The flow is shown to be nearly constant density, with a symmetric stress tensor and the principal directions of the stress and rate of strain tensors nearly colinear. The local rheology is analyzed using a coordinate transformation which enables direct computation of the viscosity and components of the pressure assuming the granular material to be a generalized Newtonian fluid. The scaled viscosity, fluctuation velocity and volume fraction are shown to follow power law relations with the inertial number, a scaled shear rate, and data for different flow rates collapse to a single curve in each case. Results for flow of the particles on an inclined surface, presented for comparison, are similar to those for the bin flow, but with a lower viscosity and a higher solid fraction due to layering of the particles. The in plane normal stresses are nearly equal and slightly larger than the third component. All three normal stresses correlate well with the corresponding fluctuation velocity components. Based on the empirical correlations obtained, a continuum model is presented for computation of granular flows.

description: This article compiles several sources of drug data to provide an analysis of supply and demand factor influencing the drug trade, including potential effects to agricultural production. All effects were found to be contemporaneously independent with the exception of coca production causing arrests in the U.S. Significant lagged effects were found linking agricultural production and coca production. Seizures and arrests were found to have a lagged deterrent effect on coca production. Seizures and arrests had lagged effects in explaining the variance of each other. It is likely that arrests increase intelligence information, resulting in more seizures and eventually more arrests.

We analyze the contributions of tbar-t-gamma production and radiative top quark decays to p-p, pbar-p -> gamma l^+/- nu bbar-b jj, assuming that both b-quarks are tagged. With 20~fb^{-1} at the Tevatron, the possibility that the ``top quark'' discovered in Run I is actually an exotic charge -4/3 quark can be ruled out at the 95% confidence level. At the LHC, it will be possible to determine the charge of the top quark with an accuracy of about 10%.

description: The global contribution of unresolved gamma-ray point sources to the extragalactic gamma-ray background has been recently measured down to gamma-ray fluxes lower than those reached with standard source detection techniques, and by employing the statistical properties of the observed gamma-ray counts. We investigate and exploit the complementarity of the information brought by the one-point statistics of photon counts (using more than 10 years of Fermi-LAT data) and by the recent measurement of the angular power spectrum of the unresolved gamma-ray background (based on 8 years of Fermi-LAT data). We determine, under the assumption that the source-count distribution of the brightest unresolved objects is dominated by blazars, their gamma-ray luminosity function and spectral energy distribution down to fluxes almost two orders of magnitude smaller than the threshold for detecting resolved sources. The different approaches provide consistent predictions for the gamma-ray luminosity function of blazars, and they show a significant complementarity.

description: Domestically funded (and performed) research and development (R&D) has historically been a major source of productivity gains in U.S. agriculture, and a principal source of R&D spillovers to the rest of the world. In the waning decades of the 20th century, U.S. policymakers opted to ratchet down the rate of growth in public support for food and agricultural R&D. As the 21st century unfolds, slowing growth gave way to real cutbacks, reversing the accumulation of U.S.- sourced public R&D capital over most of the previous century and more. The 2014 Farm Bill did little to reverse these long-run research funding trajectories—politicians apparently ignored economic evidence about the still substantial social payoffs to that research and the consequent slowdown in U.S. agricultural productivity growth associated with the spending slowdown. Meanwhile, R&D spending by other countries has been moving in different directions. We present new evidence that today’s middle-income countries—notably China, Brazil and India— are not only growing in relative importance as producers of agricultural innovations through investments in public R&D, they are also gaining considerable ground in terms of their share of privately performed research of relevance for agriculture. The changes in global public and private R&D investment trajectories are accelerating of late, and substantive. If history is any guide to the future, these changing R&D trajectories could have profound consequences for the competiveness of U.S. agriculture in the decades ahead.

description: A poor diet fostered by a rapid increase in the supply of affordable processed food has been mentioned as one of the major contributors to obesity and non-communicable diseases. Associated to increases in affordability are the promotions used by retailers. Their impact is controversial because promotions have been pointed to as a key factor in expanding the expenditure on caloric-rich processed foods, but they are also used by retailers for selling fruit and vegetables. This article focuses on the effect that retailers’ promotions have on the Scottish diet. In this respect, Scotland is an interesting case because it has one of the worst overweight and obesity records for both adults and children within the OECD countries. Most studies on the effects of promotions have been based on a single or reduced number of food products. Thus, the purpose of this paper is to analyse the overall effect of promotions on the Scottish food and drink purchases. This is achieved by analysing a representative scanner panel dataset for the period 2006-13. The methodology consists of exploring the impact of promotions on food expenditure and allocation, using for the latter an augmented with promotions linear AIDS model, while controlling by food access area, which was approximated by deprivation area. Results indicate that promotions seem to have differentiated effects by category and similar results for all the accessibility areas.

description: In this paper the heterogeneous firms and trade literature is extended by integrating quality of inputs and outputs in a food and agricultural setting. Recently, Sexton (2013) has suggested that intermediate agricultural input quality is critical in food processing firms’ output quality and pricing decisions. The results presented in this paper indicate that intermediate agricultural input quality, when combined with the quality of other food processing inputs, is important in analyzing the production decision-making of firms. Extending the model of Kugler and Verhoogen (2012), the quality of food processing inputs is integrated into the analysis in two ways: first, it affects the production of the final good, in that higher quality food processing inputs lower the marginal cost of producing the final good; and, second, food processing input quality is complementary to intermediate input quality in determining quality of the final good. By choosing these elements, firms become differentiated on a vertical (quality) level not only because of their capability draw and intermediate input quality choice, but also because of their choice of food processing inputs. Three key results are developed in the paper: first, larger firms, measured by revenue, charge a higher price for their final good, pay a higher price for their inputs, and produce a higher quality final good. Second, firms that produce for export destinations with a higher preference for quality, choose higher-quality inputs. Third, if preference for quality increases in export-destinations new firms enter the export market, while less capable firms are forced to exit.

They can be composed in order to add or remove static and dynamic observations. A second-order circumscription operator then enables nonmonotonic reasoning on the changes implied by a formula. We introduce deduction rules that produce formulas which are, up to equivalence, in a first-order fragment with decidable satisfiability and validity. Importantly, the rules can produce circumscribed formulas.

description: Universal access to modern energy services, in terms of access to electricity and to modern cooking facilities, has been recognized as fundamental challenge for development and is likely to be included in the post-2015 Sustainable Development Goals. Despite a strong praise for action and several programs at both national and international level, very few impact evaluation studies try to shed light on the causal relationship between access to energy and development, by also allowing decision makers to rigorously assess cost-effectiveness and efficiency of policies and programs. This work attempts to review the literature on existing impact evaluation of access to electricity and modern cooking facilities. For access to electricity we consider as outcomes labour markets, time allocation, household welfare (consumption, income, schooling and health) and business. For access to improved cookstoves, we assess impacts on household welfare. The reviewed literature highlights a significant causal impact of electricity access on important metrics of wellbeing, but more mixed evidence regarding clean cookstove. Finally, we also review the barriers and drivers of access to modern energy services identified by most recent impact evaluation studies.

description: Designers and artists world-wide rely on vector graphics to design and edit 2D artwork, illustrations and typographic content. There is a recent trend of vector graphic applications moving to mobile platforms such as iPads, iPhone and mobile phones and with that there is new interest in optimised techniques of rendering vector graphics on these devices. These vector applications are not read only but also requires real time vector editing experience. Our solution builds upon standard 'stencil then cover' paradigm and develops an algorithm targeted for GPUs based on tile based deferred rendering architecture. Our technique provides an efficient way to use signed distance based anti-aliasing techniques with 'stencil then cover' paradigm by employing a state machine during the fragment shader stage of graphics pipeline.

Heavy and Light Quarks with Lattice Chiral Fermions

Year: 2002
Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: The feasibility of using lattice chiral fermions which are free of $O(a)$ errors for both the heavy and light quarks is examined. The fact that the effective quark propagators in these fermions have the same form as that in the continuum with the quark mass being only an additive parameter to a chirally symmetric antihermitian Dirac operator is highlighted. This implies that there is no distinction between the heavy and light quarks and no mass dependent tuning of the action or operators as long as the discretization error $O(m^2 a^2)$ is negligible. Using the overlap fermion, we find that the $O(m^2a^2)$ (and $O(ma^2)$) errors in the dispersion relations of the pseudoscalar and vector mesons and the renormalization of the axial-vector current and scalar density are small. This suggests that the applicable range of $ma$ may be extended to $\sim 0.56$ with only 5% error, which is a factor of $\sim 2.4$ larger than that of the improved Wilson action. We show that the generalized Gell-Mann-Oakes-Renner relation with unequal masses can be utilized to determine the finite $ma$ errors in the renormalization of the matrix elements for the heavy-light decay constants and semileptonic decay constants of the B/D meson.

 Type information: Holotype M, TURKEY: Mersin, Mut, Sertavul Geçidi, 1600 m, 21.9.1995 (B. Çıplak) (NHM); Paratype 1F, same data as holotype (AUZM).

 Distribution: This species is restricted to the western part of Mersin province in Eastern Mediterranean Turkey.
 Remarks: Ünal (2006) reported that E. femorata may be a synonym of E. unimacula. This conclusion was mainly based on the probability of the presence of styli at the hind margin of the subgenital plate in the holotype of E. unimacula, since presence/absence of styli was considered to be one of the diagnostic characters of these species by Çıplak (1999). During this study, type material and new specimens of these two species were examined. Although both species share numerous similarities and there is a possibility of loosing of styli in E. unimacula, there are further diagnostic characters that support the assumption that each is an independent evolutionary unit. Especially, the long unfused part of apical arms of the titillators (longer than fused part) and the shallow incision of the female subgenital plate (less than half the medial length) in E. femorata separates it distinctly from E. unimacula, in which the unfused parts of the apical arms are shorter than the fused part and the incision of the female subgenital plate is deeper than half the medial length (compare Figures 226, 227). Thus, each of them was considered to be a separate taxon.

description: In the paper we provide an explanation of the persistence of the commodity titles in US farm bills that is grounded in core theories of the policy process from the political science literature. The political science literature explains policy continuity and policy change from a number of different perspectives and we use these to explain why the commodity titles of farm bills have persisted in the face of considerable opposition and how in response the Agriculture Committees have introduced incremental change to the content of farm bills to facilitate each bill’s passage. Unlike the standard approach of agricultural economists which focuses on the broader national economic efficiency impacts of farm programs, we concentrate on, narrower local political forces that affect individual Members of the Congress, and on the legislative process that created each farm bill.

description: Im Rahmen dieser explorativen Fallstudie wurde untersucht, was die Erwartungen an eine digitale nutzerorientierte Compliance und Bedürfnisse kleinerer und mittlerer Organisationen, insbesondere KMUs (kleinere und mittlere Unternehmen) sowie der mit ihnen verbundenen Stakeholder resp. Stakeholdergruppen sind. Denn die Digitalisierung erlaubt es, Compliance-Inhalte zu personalisieren und in Bezug auf die jeweiligen Bedürfnisse und Anforderungen der jeweiligen NutzerInnen verfügbar zu machen. Die Daten der Studie wurden im Rahmen von Interviews sowie einem Design-Thinking-Workshop mit ausgewählten Compliance-ExpertInnen, Verantwortlichen und -NutzerInnen gewonnen. Alle Daten wurden vertraulich behandelt und alle in dieser Studie zitierten Studienteilnehmenden haben der Zitierung ausdrücklich zugestimmt. Sie geben hier nur ihre persönliche Sicht wieder.
Aus den Interviews wurden fünf Prototypen, sogenannte Personas, abgeleitet, für eine Gruppe von NutzerInnen mit konkret ausgeprägten Eigenschaften und einem konkreten Nutzungsverhalten, welche die Bedürfnisse und Anforderungen an die Compliance darstellen. Im Rahmen des Workshops und in Bezugnahme auf die aus den Interviews hervorgegangenen Personas wurden vier Compliance-Systeme für digitale Compliance-Lösungen entwickelt. Die aus den beiden Prozessen abgeleiteten Erkenntnisse wurden schliesslich zusammengefasst, woraus nicht nur erste Hypothesen abgeleitet werden konnten, sondern es wurde auch möglich, drei Lösungsebenen für digitale Compliance-Inhalte abzuleiten. Während die Hypothese in nun folgenden Studien weiter zu vertiefen wäre, können die abgeleiteten Lösungsebenen als Basis dienen für die Entwicklung entsprechender digitaler Compliance-Systeme, die die Bedürfnisse von Organisationen und der mit ihnen verbundenen Stakeholder resp. Stakeholdergruppen erfüllen.

description: The three flavor soliton approach for baryons is utilized to discuss effects of flavor symmetry breaking in the baryon wave--functions on axial current matrix elements. The flavor content of the singlet axial current matrix elements, that parameterizes the quark spin contribution to the total angular momentum, is disentangled and studied as a function of the effective flavor symmetry breaking. Here the nucleon and the Lambda--hyperon are considered.

description: Rotational mixing, the key process in stellar evolution, transports angular momentum and chemical elements in stellar radiative zones. In the past two decades, an emphasis has been placed on the turbulent transport induced by the vertical shear instability. However, instabilities arising from horizontal shear and the strength of the anisotropic turbulent transport that they may trigger remain relatively unexplored. This paper investigates the combined effects of stable stratification, rotation, and thermal diffusion on the horizontal shear instabilities in the context of stellar radiative zones. The eigenvalue problem describing linear instabilities of a flow with a hyperbolic-tangent horizontal shear profile was solved numerically for a wide range of parameters. As a first step, we consider a polar $f$-plane where the gravity and rotation vector are aligned. Two types of instabilities are identified: the inflectional and inertial instabilities. The inflectional instability that arises from the inflection point is the most unstable when at a zero vertical wavenumber and a finite wavenumber in the streamwise direction along the imposed-flow direction. The three-dimensional inflectional instability is destabilized by stratification, while it is stabilized by thermal diffusion. The inertial instability is rotationally driven, and a WKBJ analysis reveals that its growth rate reaches the maximum $\sqrt{f(1-f)}$ in the inviscid limit as the vertical wavenumber goes to infinity, where $f$ is the dimensionless Coriolis parameter. The inertial instability for a finite vertical wavenumber is stabilized as the stratification increases, whereas it is destabilized by the thermal diffusion. Furthermore, we found a self-similarity in both the inflectional and inertial instabilities based on the rescaled parameter $PeN^2$ with the Péclet number $Pe$ and the Brunt-Väisälä frequency $N$.

description: We study the effect of quenched random field disorder on a driven elastic interface close to the depinning transition at the upper critical dimension d_{c}=4 using the functional renormalization group. We have found that the displacement correlation function behaves with distance x as ln(x)^{2/3} for large x. Slightly above the depinning transition the force-velocity characteristics is described by the equation v ~ f |ln(f)|^{2/9}, while the correlation length behaves as L_{v} ~ f^{-1/2}|ln(f)|^{1/6}, where f=F/F_{c}-1 is the reduced driving force.

Optical Kerr effect in vacuum

description: From an effective field theory of electromagnetism in vacuum including all lowest-order nonlinear terms consistent with Lorentz invariance and locality of photon/photon interactions, we derive an effective medium description of strong background fields as regards their influence on a weak probe. We mainly consider as background a pump beam with well-defined wave vector and polarization. This leads us to define a nonlinear index of vacuum which, in the Euler-Heisenberg model derived from QED, has an optimal value of $1.555 \times 10^{-33} \, {\rm cm}^{2}/{\rm W}$ for a linearly polarized pump as seen by a counter-propagating, orthogonally polarized probe. We further generalize the model to include coupling to an axion field. In the limit where the axion mass is much smaller than the typical photon energy, this yields dispersive corrections, and the axionic signature is found to be greatly enhanced for a circularly polarized pump as compared to a linearly polarized one. The formalism here presented points to a simplification of the DeLLight experiment [X. Sarazin et al., Eur. Phys. J. D 70, 13 (2016)] aiming to measure the deflection of a probe by a tightly focused laser pulse.

description: Intestinal metaplasia (IM) is a pre-malignant condition of the gastric mucosa associated with increased gastric cancer (GC) risk. Analyzing 1,256 gastric samples (1,152 IMs) across 692 subjects from a prospective 10-year study ,we identify 26 IM driver genes in diverse pathways including chromatin regulation (ARID1A) and intestinal homeostasis (SOX9). Single-cell and spatial profiles highlight changes in tissue ecology and IM lineage heterogeneity, including an intestinal stem-cell dominant cellular compartment linked to early malignancy. Expanded transcriptome profiling reveals expression-based molecular subtypes of IM associated with incomplete histology, antral/intestinal cell types, ARID1A mutations, inflammation, and microbial communities normally associated with the healthy oral tract. We demonstrate that combined clinical-genomic models outperform clinical-only models in predicting IMs likely to transform to GC. By highlighting strategies for accurately identifying IM patients at high GC risk and a role for microbial dysbiosis in IM progression, our results raise opportunities for GC precision prevention and interception.
