description: This study evaluates potential economic impacts on the region that may result from diversifying into vegetable crops. Five vegetables: okra, Southern peas, snap beans, summer squash, and sweet potatoes are evaluated. The evaluations entail analyses of potential regional economic impacts, using IMPLAN 3.0. The results exhibit strong multiplier effects and economic contributions in the region to output, employment, value-added, and income generation. The results also show that vegetable production can be important source of indirect and induced economic activities in the region. These indicate that vegetable production can have positive impacts and linkages in the region’s economy and may not be ignored in developing economic strategies for the region

Toward a Balance Between Strategic-Basic and Applied Agricultural Research

Year: 1996
Subjects: Research Methods/ Statistical Methods

description: Strategic-basic research refers to basic research conducted in strategically selected areas expected to be of social benefit. Recent literature on the processes of basic research and its linkages to applied research has not be widely discussed in relation to agricultural research. It is proposed that the literature may have important implications for the question of the optimal allocation of research resources between strategic-basic and applied research. The linkages are reviewed and combined into a framework for considering the allocation question. An illustrative numerical model based on this framework suggests that only a small number of the model's parameters substantially affect the optimal level of basic research, and that it is not important to identify the optimal solution very precisely, since the benefit function is extremely flat for a wide region around the optimum.

description: As has been previously proposed, a minimal modification of the standard $SU(3)\times SU(2)\times U(1)$ theory provides a viable dark matter candidate. Such a particle, a scalar gauge singlet, is naturally self-interacting---making it of particular interest given recent developments in astrophysics. We review this dark matter candidate, with reference to the parameter ranges currently under discussion.

description: Many small towns are adopting community-based economic development strategies, such as community-owned firms and community-oriented finance institutions, to promote development. On the plus side, such projects have created jobs, promoted a sense of local ownership, and retained much of the created revenue within the community. On the down side, the number of jobs created or saved has been modest, access to capital can be difficult, and managerial experience is often limited.
Vertex Operators in IIB Matrix Model

description: The vertex operators for the supergravity multiplet can be constructed through the Wilson lines in IIB matrix model. We investigate the structure of the vertex operators and the symmetry of their correlation functions. For this purpose, we perturb the theory by the Wilson lines dual to the supergravity multiplet. The structure of the Wilson lines can be determined by requiring $\cal{N}$=2 SUSY under the low energy approximation. We argue that the generating functional of the correlators is invariant under local SUSY transformations of IIB supergravity.

Logarithmic loop corrections, moduli stabilisation and de Sitter vacua in string theory

description: We study string loop corrections to the gravity kinetic terms in type IIB compactifications on Calabi-Yau threefolds or their orbifold limits, in the presence of $D7$-branes and orientifold planes. We show that they exhibit in general a logarithmic behaviour in the large volume limit transverse to the $D7$-branes, induced by a localised four-dimensional Einstein-Hilbert action that appears at a lower order in the closed string sector, found in the past. Here, we compute the coefficient of the logarithmic corrections and use them to provide an explicit realisation of a mechanism for Kähler moduli stabilisation that we have proposed recently, which does not rely on non-perturbative effects and lead to de Sitter vacua. Our result avoids no-go theorems of perturbative stabilisation due to runaway potentials, in a way similar to the Coleman-Weinberg mechanism, and provides a counter example to one of the swampland conjectures concerning de Sitter vacua in quantum gravity, once string loop effects are taken into account; it thus paves the way for embedding the Standard Model of particle physics and cosmology in string theory.

On the Work of Madhu Sudan: the 2002 Nevalinna Prize Winner
Creators: name: Goldwasser, Shafi
Publisher: name: arXiv
Year: 2002
Subjects: subject: Computational Complexity (cs.CC)
subject: FOS: Computer and information sciences

description: Madhu Sudan's work spans many areas of computer science theory including computational complexity theory, the design of efficient algorithms, algorithmic coding theory, and the theory of program checking and correcting. Two results of Sudan stand out in the impact they have had on the mathematics of computation. The first work shows a probabilistic characterization of the class NP -- those sets for which short and easily checkable proofs of membership exist, and demonstrates consequences of this characterization to classifying the complexity of approximation problems. The second work shows a polynomial time algorithm for list decoding the Reed Solomon error correcting codes. This short note will be devoted to describing Sudan's work on probabilistically checkable proofs -- the so called {\it PCP theorem} and its implications.

description: In November of 1970 the U.S. National Marine Fisheries Service, its Division of Economic Research, held a subject workshop which was attended by 60 persons from broad research backgrounds, including representatives from the British Whitefish Authority, the ORganization fro Economic Co-operation and Development, and Food and Agricultural Fisheries and Forestry, as well as representatives of U.S. government agencies and universities. Research topics ranged from production economics and bio-economic models to general discussions of management for both conservation and economic purposes, the political framework involved. This paper summarizes the key issues in the 16 papers presented at that Workshop and the discussions that resulted. The highlights of these issues are presented to this symposium in the form of suggested critical problems which must urgently be faced by the professionals gathered here.

description: We reconsider the origin of CP violation in fundamental theory. Existing string models of spontaneous CP violation make ambiguous predictions, due to the arbitrariness of CP transformation and the apparent non-invariance of the results under duality. We find an unambiguous modular CP invariance condition, applicable to predictive models of spontaneous CP violation, which circumvents these problems; it strongly constrains CP violation by heterotic string moduli. The dilaton is also evaluated as a source of CP violation, but is likely experimentally excluded. We consider the prospects for explaining CP violation in strongly-coupled strings and brane worlds.

Feasibility study of a compact Neutron Resonance Transmission Analysis instrument

description: Neutron Resonance Transmission Analysis (NRTA) uses resonant absorption of neutrons to infer the absolute isotopic composition of a target object, enabling applications in a broad range of fields such as archaeology, materials analysis of nuclear fuel, and arms control treaty verification. In the past, NRTA involved large user facilities and complex detector systems. However, recent advances in the intensity of compact neutron sources have made compact neutron imaging designs increasingly feasible. This work describes the Monte Carlo (MC) based design of a compact epithermal NRTA radiographic instrument which uses a moderated, compact deuterium-tritium (DT) neutron source and an epithermal neutron detector. Such an instrument would have a wide range of applications, and would be especially impactful for such scenarios as nuclear inspection and arms control verification exercises, where system cost and mobility may be of critical importance. The MC simulations presented in this work demonstrate accurate time-of-flight (TOF) reconstructions for transmitted neutron energies, capable of differentiating isotopic compositions of nuclear material with high levels of accuracy. A new generation of miniaturized and increasingly more intense neutron sources will allow this technique to achieve measurements with greater precision and speed, with significant impact on a variety of engineering and societal problems.

Two-gluon form factor of the nucleon and $J/ψ$ photoproduction
Creators: name: Frankfurt, Leonid

Publisher: name: arXiv
Year: 2002
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We argue that the t-dependence of the two-gluon form factor of the nucleon should be given by $Γ(t)=(1-t/m_{2g}^2)^{-2}$ with $m_{2g}^2\approx 1 GeV^2$. We demonstrate that this form provides a good description of the t-dependence of the cross section of the elastic photoproduction of $J/ψ$-mesons between the threshold region of $E_γ=11 GeV$ (Cornell), $E_γ=19 GeV$ (SLAC) and $E_γ=100 GeV$ (FNAL) including the strong energy dependence of the t-slope. It is also well matched with the recent HERA data. The same assumption explains also the t-dependence of $ϕ$-meson electroproduction near threshold at $W=2.3 GeV, Q^2=1.0 GeV^2$.

description: Convergence processes are based on the activity of distinct industry sectors showing cross-industry collaborations. The aim of this paper is to analyze cross-industry collaborations between the food and pharmaceutical sectors in the convergence area of functional foods. Selected companies from food (Nestlé/Danone) and pharmaceutical (Martek/Bayer HealthCare) sectors are analyzed using the determinants of motivation and industrial scope. The analysis shows that food companies are more active in cross-industry collaborations than pharmaceutical companies. The latter are more active at the front-end of the value chain focusing on research and development, and delivering their ingredients to food companies that due to their higher expertise in consumer marketing launch the products. While the first cross-industry collaborations were based on an exploration motivation, those that follow focus on exploitation. Acquisitions and licensing agreements are dominant in inside-out and outside-in processes, whereas strategic alliances and joint ventures are based on a coupled process between the food and pharmaceutical sectors.

description: A 3D copepod trajectory is recorded in the laboratory, using 2 digital cameras. The copepod undergoes a very structured type of trajectory, with successive moves displaying intermittent amplitudes. We perform a statistical analysis of this 3D trajectory using statistical tools developed in the field of turbulence and anomalous diffusion. We show that the walk belongs to "multifractal random walks", characterized by a nonlinear moment scaling function for the distance versus time. To our knowledge, this is the first experimental study of multifractal anomalous diffusion. We then propose a new type of stochastic process reproducing these multifractal scaling properties. This can be directly used for stochastic numerical simulations, and is thus of important potential applications in the field of animal movement study, and more generally of anomalous diffusion studies.

description: Combinatorics is a fundamental mathematical discipline as well as an essential component of many mathematical areas, and its study has experienced an impressive growth in recent years. One of the main reasons for this growth is the tight connection between Discrete Mathematics and Theoretical Computer Science, and the rapid development of the latter. While in the past many of the basic combinatorial results were obtained mainly by ingenuity and detailed reasoning, the modern theory has grown out of this early stage, and often relies on deep, well developed tools. This is a survey of two of the main general techniques that played a crucial role in the development of modern combinatorics; algebraic methods and probabilistic methods. Both will be illustrated by examples, focusing on the basic ideas and the connection to other areas.

description: Health-related quality of life (HRQoL) is a health indicator that indicates the individual’s overall perception of physical, psychological, and social well-being. Air pollution potentially affects the individual’s HRQoL. However, the evidence about the effects of air pollution on HRQoL, particularly in adolescents, remains limited. This study explored the effects of air pollution exposure on adolescents’ HRQoL. Data were collected from a population-based cross-sectional survey conducted in Shandong Province of China. The Tobit regression model (Tobit-CF) combined with the control function (CF) based on instrumental variables was used as the main regression model, and causal mediation analysis was conducted to explore the mechanism with the time spent on outdoor activity (OA) as the mediator. The final analysis included a total of 266,138 adolescents with an average age of 13 years. This study found that long-term exposure to air pollution would impair the adolescent’s HRQoL, with the decrease in outdoor activities potentially serving as a mediator. Compared to males and older adolescents, females, and younger adolescents are more susceptible to experiencing HRQoL impairment induced by air pollution exposure. The empirical strategy used in this study also provides the reference and insight for future environmental health research to infer causality using cross-sectional data.

Using structural equation modeling, we examined the role of entrepreneurial and market orientation on the effectiveness of new product sales and the utilization of marketing channels among farm-based businesses in Ontario, Canada. We also investigated the relationship between perceived environmental turbulence and the use of strategic resources. Findings show that Ontario agri-businesses who are entrepreneurial and market oriented are more likely to adopt new and/or significantly improved products and services while using multiple marketing channels. Furthermore, it was shown that environmental turbulence increases the degree of entrepreneurial and market orientation in these firms.

We point out a mechanism by which string scale unification may occur while producing a (lower) virtual unification scale independent of the location of the intermediate scale and the value of the string coupling. The apparent unification obtained by extrapolating low energy gauge couplings is not accidental when this mechanism is invoked; virtual unification is robust.

The attributes examined are: an online marketplace, social media advertisement of farms, different operators of the marketing platforms, an online directory, and monthly fee levels. The results in this study indicate heterogeneity in producers’ preferences. Specifically, farmers can be divided into two distinct groups: producers interested in electronic food trading platforms, and producers who are not interested in them. Producers in the first group are willing to pay $70 per month for an online marketplace and $152 per month for the service. Lastly, farmers have a slight preference for a for-profit operator when compared to a not-for-profit operator.

From the diverging parts of the diagrams, we obtain the renormalization constant of the vacuum Z_v which also contains information on the critical exponent alpha of the specific heat. As a side result, we use an earlier two-loop calculation of the effective potential (H.K. and B.VdB., Phys.Rev.

This anomaly is not associated to a dynamical chiral fermion degree of freedom, but rather should be regarded as an explicit flux-induced anomalous term (Wess-Zumino term) in the action. The anomaly is cancelled by an inflow mechanism, which exploits the fact that fluxes can act as sources of RR fields. We discuss several applications of this flux-induced anomaly; among others, its role in understanding anomaly cancellation in compactifications with D-branes and fluxes, and the possibility of phase transitions where a chiral fermion disappears from the D-brane world-volume spectrum, being replaced by an explicit Wess-Zumino term. We comment on the relation among different mechanisms to obtain four-dimensional chirality in string theory.

description: We present a first, consistent combination of measurements from top-quark and $B$ physics to constrain top-quark properties within the Standard Model Effective Field Theory (SMEFT). We demonstrate the feasibility and benefits of this approach and detail the ingredients required for a proper combination of observables from different energy scales. Specifically, we employ measurements of the $t\bar tγ$ cross section together with measurements of the $\bar B\rightarrow X_sγ$ branching fraction to test the Standard Model and look for new physics contributions to the couplings of the top quark to the gauge bosons within SMEFT. We perform fits of three Wilson coefficients of dimension-six operators considering only the individual observables as well as their combination to demonstrate how the complementarity between top-quark and $B$ physics observables allows to resolve ambiguities and significantly improves the constraints on the Wilson coefficients. No significant deviation from the Standard Model is found with present data.

description: Differential complexes such as the de Rham complex have recently come to play an important role in the design and analysis of numerical methods for partial differential equations. The design of stable discretizations of systems of partial differential equations often hinges on capturing subtle aspects of the structure of the system in the discretization. In many cases the differential geometric structure captured by a differential complex has proven to be a key element, and a discrete differential complex which is appropriately related to the original complex is essential. This new geometric viewpoint has provided a unifying understanding of a variety of innovative numerical methods developed over recent decades and pointed the way to stable discretizations of problems for which none were previously known, and it appears likely to play an important role in attacking some currently intractable problems in numerical PDE.

description: O discurso ocidental, tão difundido enquanto ápice da modernidade pautada na racionalidade iluminista e na perspectiva universalista de civilização e etnocêntrico e excludente. É na resistência político-cultural a colonialidade imposta pela modernidade por meio da racionalidade e epistemologia que o intelectual mexicano Leopoldo Zea (1912-2004) se insere no debate intelectual latino-americano. O eurocentrismo enquanto, ideologia e processo histórico são interpretados à luz da realidade e da “concepção histórico-filosófica periférica” latino-americana e do eixo sul global. Busca-se, desta maneira, perceber a construção narrativa de uma filosofia própria para a América Latina no século XX, através do discurso de Zea, que leve em consideração à relação com regiões do mundo exploradas pelo colonialismo e o capitalismo. A metodologia utilizada será a leitura estrutural e analítica dos textos originais do filósofo em questão, e sua confrontação com os trabalhos desenvolvidos pelo grupo colonialidade decolonialidade. Os conceitos selecionados ao longo da argumentação Zeana buscarão responder e evidenciar quais as problemáticas discutidas em torno da modernidade, eurocentrismo e seu impacto na filosofia latino-americana.
Thermal history modeling of the L chondrite parent body

description: The radius of the L chondrite parent body, its formation time, and its evolution history are determined by fitting theoretical models to empirical data of radioisotopic chronometers for L chondrites. A simplified evolution model for the L chondrite parent body is constructed considering sintering of the initially porous material, temperature dependent heat conductivity, and an insulating regolith layer. Such models are fitted to thermochronological data of five meteorites for which precise data for the Hf-W and U-Pb-Pb thermochronometers have been published. A set of parameters for the L chondrite parent body is found that yields excellent agreement (within error bounds) between a thermal evolution model and thermochonological data. Empirical cooling rate data also agree with the model results within error bounds such that there is no conflict between cooling rate data and the onion-shell model. Two models are found to be compatible with the presently available empirical data: One model with a radius of 115 km and a formation time of 1.89 Ma after CAI formation, another model with 160 km radius and formation time of 1.835 Ma. The central temperature of the smaller body remains well below the Ni,Fe-FeS eutectic melting temperature and is consistent with the apparent non-existence of primitive achondrites related to the L chondrites. For the bigger model incipient melting in the central core region is predicted which opens the possibility that primitive achondrites related to L chondrites could be found.

description: In recent years, public and private food safety standards in the EU have proliferated and grown stricter while food prices and demand in these markets have been stagnating. The opposite is true for many emerging and transitional countries that are experiencing an increase in purchasing power and demand. However, these countries often have lower food safety standards than in the EU. In response to current trends in international food trade, this study seeks to determine whether traders in developing–transitioning countries and in industrialized European countries (especially Germany), are experiencing changes in trade flows in the international fresh-fruit trade and also identify the role of private standards in connection with relevant situational factors driving these changes. Underlying assumptions are derived from the concepts of the contingency approach. To obtain qualitative data, a series of semi-structured telephone interviews were conducted with industry experts from fourteen import countries and twenty-two export companies. Based on the results of a structured content analysis of these interviews, appropriate political, managerial and research implications are developed promoting the liberalization and harmonization of public and private maximum residue levels for fruits within the EU.

description: Arsenic is a natural element in soil, but concentrations may be increased through anthropogenic sources. Exposure to elevated arsenic concentrations may cause adverse effects and multiple internal organ cancers. Soil properties can profoundly impact the bioavailability of arsenic and subsequent risk to human health. Agricultural lands in Miami-Dade County, Florida, USA (MDC) are comprised of calcareous soil, and it was hypothesized that the soil chemistry of South Florida soil may reduce arsenic bioavailability. The purpose of this study was to determine whether soil properties can be used as a quick and cost-effective surrogate to accurately predict the oral bioavailability of arsenic in soils. This study utilized samples taken throughout MDC. Relationships to predicted bioavailability were evaluated by pH, soil type, soil classification, and sampling location. Significant differences in mean predicted relative bioavailability (RBA) were noted based on soil type and location in MDC (p < 0.05). Although statistical differences were noted in predicted RBA, the variability within each category suggests none of the soil properties evaluated are appropriate surrogates for predicting oral bioavailability for MDC soils. In the absence of a practical surrogate, a site-specific predicted RBA for arsenic in MDC soils should be obtained when total arsenic concentrations exceed cleanup levels.

description: Increased interest by consumers and producers in grass-fed beef has led to recent expansions in this segment of the beef industry. A mailed survey was used to determine the “what, where and how” of grass-fed, beef marketing in the United States. The most important factors in farmers’ decisions on when to harvest and sell cattle are animal weight and consumer demand. Most farmers use multiple venues for advertising and marketing their beef. Direct sale to consumer is the most commonly used marketing channel. Farm experience, diversification, farm size, production system, and production region impact marketing channel choice.

Comparative simulation study of colloidal gels and glasses

description: Using computer simulations, we identify the mechanisms causing aggregation and structural arrest of colloidal suspensions interacting with a short-ranged attraction at moderate and high densities. Two different non-ergodicity transitions are observed. As the density is increased, a glass transition takes place, driven by excluded volume effects. In contrast, at moderate densities, gelation is approached as the strength of the attraction increases. At high density and interaction strength, both transitions merge, and a logarithmic decay in the correlation function is observed. All of these features are correctly predicted by mode coupling theory.
