description: Depletion of groundwater resources is an international problem, and groundwater is probably the world’s most extracted raw material. The agriculture sector is one of the biggest users of groundwater resources for irrigation activities, and it plays an important role in the depletion of these resources. The estimation of demand function for groundwater resources is the first step toward any policy recommendation in this field of research. However, only scarce attention has been given to empirical studies of the demand structure of groundwater resources by the help of econometrics and considering the quality of the resources in the context of a single aquifer. Therefore, an empirical estimation of the demand function for individual users which considers water quality enhances further economic analysis and results in better policy recommendations. In this study, we have analysed the economic factors and the groundwater quality as influencing variables on derived demand function for irrigation water in the pistachio production of the Rafsanjan aquifer in the southeastern part of Iran. The field study was conducted from November 2008- February 2009. Translog cost function has been applied for the estimation of the derived demand function for groundwater in pistachio production and its shadow price. The spatial econometrics has been applied to correct the results. Results show that water pumping costs are much less than their shadow prices.

description: We investigate theoretically the non-equilibrium transport properties of carbon nanotube quantum dots. Owing to the two-dimensional band structure of graphene, a double orbital degeneracy plays the role of a pseudo-spin, which is entangled with the spin. Quantum fluctuations between these four degrees of freedom result in an SU(4) Kondo effect at low temperatures. This exotic Kondo effect manifests as a four-peak splitting in the non-linear conductance when an axial magnetic field is applied.

description: Robustness of a distributed computing system is defined as the ability to maintain its performance in the presence of uncertain parameters. Uncertainty is a key problem in heterogeneous (and even homogeneous) distributed computing systems that perturbs system robustness. Notably, the performance of these systems is perturbed by uncertainty in both task execution time and arrival. Accordingly, our goal is to make the system robust against these uncertainties. Considering task execution time as a random variable, we use probabilistic analysis to develop an autonomous proactive task dropping mechanism to attain our robustness goal. Specifically, we provide a mathematical model that identifies the optimality of a task dropping decision, so that the system robustness is maximized. Then, we leverage the mathematical model to develop a task dropping heuristic that achieves the system robustness within a feasible time complexity. Although the proposed model is generic and can be applied to any distributed system, we concentrate on heterogeneous computing (HC) systems that have a higher degree of exposure to uncertainty than homogeneous systems. Experimental results demonstrate that the autonomous proactive dropping mechanism can improve the system robustness by up to 20%.

description: The agricultural commodity crisis of 2006-8 and the recent evolution of commodity markets have reignited anxieties in Finland over fast-rising food prices and food security. Although the impact of farm commodity price shocks on the final consumer is mitigated by a large degree of processing as well as the complex structure of the food chain, little is known about the strength of the linkages between food markets and input markets. Using monthly series of price indices from 1995 to 2010, we estimate a vector error-correction (VEC) model in a co-integration framework in order to investigate the short-term and long-term dynamics of food price formation. The results indicate that a statistically significant long-run equilibrium relationship exists between the prices of food and those of the main variable inputs consumed by the food chain, namely agricultural commodities, labour, and energy. When judged by the magnitude of long-run pass-through rates, farm prices represent the main determinant of food prices, followed by wages in food retail and the price of energy. However, highly volatile energy prices are also important in explaining food price variability. The parsimonious VEC model suggests that the dynamics of food price formation is dominated by a relatively quick process of adjustment to the long-run equilibrium, the half life of the transitional dynamics being six to eight months following a shock.

description: In a study of the influence of ZrB2 additions on the irreversibility field, Birr and the upper critical field Bc2, bulk samples with 7.5 at. % ZrB2 additions were made by a powder milling and compaction technique. These samples were then heated to 700-900C for 0.5 hours. Resistive transitions were measured at 4.2 K and Birr and Bc2 values were determined. An increase in Bc2 from 20.5 T to 28.6 T and enhancement of Birr from 16 T to 24 T were observed in the ZrB2 doped sample as compared to the binary sample at 4.2 K. Critical field increases similar to those found with SiC doping were seen at 4.2 K. At higher temperatures, increases in Birr were also determined by M-H loop extrapolation and closure. Values of Birr which were enhanced with ZrB2 doping (as compared to the binary) were seen at temperatures up to 34 K, with Birr values larger than those for SiC doped samples at higher temperatures. The transition temperature, Tc, was then measured using DC susceptibility and a 2.5 K drop of the midpoint of Tc was observed. The critical current density was determined using magnetic measurements and was found to increase at all temperatures between 4.2 K and 35 K with ZrB2 doping.

description: Unsupervised domain adaptation~(UDA) aims at reducing the distribution discrepancy when transferring knowledge from a labeled source domain to an unlabeled target domain. Previous UDA methods assume that the source and target domains share an identical label space, which is unrealistic in practice since the label information of the target domain is agnostic. This paper focuses on a more realistic UDA scenario, i.e. partial domain adaptation (PDA), where the target label space is subsumed to the source label space. In the PDA scenario, the source outliers that are absent in the target domain may be wrongly matched to the target domain (technically named negative transfer), leading to performance degradation of UDA methods. This paper proposes a novel Target Domain Specific Classifier Learning-based Domain Adaptation (TSCDA) method. TSCDA presents a soft-weighed maximum mean discrepancy criterion to partially align feature distributions and alleviate negative transfer. Also, it learns a target-specific classifier for the target domain with pseudo-labels and multiple auxiliary classifiers, to further address classifier shift. A module named Peers Assisted Learning is used to minimize the prediction difference between multiple target-specific classifiers, which makes the classifiers more discriminant for the target domain. Extensive experiments conducted on three PDA benchmark datasets show that TSCDA outperforms other state-of-the-art methods with a large margin, e.g. $4\%$ and $5.6\%$ averagely on Office-31 and Office-Home, respectively.

description: We examine a strategy for using neutral current measurements in long-baseline neutrino oscillation experiments to put limits on the existence of more than three light, active neutrinos. We determine the relative contributions of statistics, cross section uncertainties, event misidentification and other systematic errors to the overall uncertainty of these measurements. As specific case studies, we make simulations of beams and detectors that are like the K2K, T2K, and MINOS experiments. We find that the neutral current cross section uncertainty and contamination of the neutral current signal by charge current events allow a sensitivity for determining the presence of sterile neutinos at the 0.10--0.15 level in probablility.

description: We constructed a model of neutrino masses using Froggatt-Nielsen mechanism with $U(1) \times Z_3 \times Z_2$ flavor symmetry. The model predicts that $(2/3)m_2/m_3 \sim \sqrt{2}\sinθ_{13}$ at lepton number violating scale $M_1$. It is shown that the small values for $m_2/m_3$ and $\sinθ_{13}$ are consequences of breaking discrete symmetries.

description: The objective of this paper was to verify the market power of the Argentinean, Brazilian and American exports of soymeal to the European Union, the main consumer market of this commodity. For that, the article is based on the methodology of residual demand. Using the methods Seemingly Unrelated Regression (SUR), Two-Stage Least Squares (2SLS) and Three-Stage Least Squares (3SLS), the results indicated that, though this segment is concentrated by Argentina, Brazil and the United States, none of these countries presented market power for soymeal exports. In other words, they are not able to change soymeal prices without to decrease the exports

description: We present a protocol to deterministically prepare the electromagnetic field in a large photon number state. The field starts in a coherent state and, through resonant interaction with one or few two-level systems, it evolves into a coherently displaced Fock state, without any post-selection. We show the feasibility of the scheme under realistic parameters. The presented method opens a door to reach Fock states with $n\sim100$ and optimal fidelities above $70$%, blurring the line between macroscopic and quantum states of the field.

description: The aim of this paper is to check if there is a relation between the wheat prices of the Argentinian and the International market, if these markets are integrated in space. For that, it was used as time reference the period from January, 1994 to April, 2009. Unit root tests, Granger causality, Johansen cointegration, estimation of the impulse response function, decomposition of error variation and estimation and analysis of the error correction model were used. The results indicated that variations in the international prices of wheat were almost completely transmitted for the run long. However, it is not possible to affirm that the Argentinian and the International markets are perfectly integrated even if they have a higher transmission of prices This is because the hypothesis of perfect integration between the markets is rejected when restrictions were imposed to the coefficients related to the long run. It was also noticed through the exogeneity test that the Argentinian wheat prices react to transient imbalances occurred in prices from the international market. Therefore, wheat prices in international markets affect the price levels in Argentina.

description: We report an increase of up to 60% on the count rates of the rare $^{81}\mathrm{Kr}$ and $^{85}\mathrm{Kr}$ isotopes in the Atom Trap Trace Analysis method by enhancing the production of metastable atoms in the discharge source. Additional atoms in the metastable $ 1s_5 $ level (Paschen notation) are obtained via optically pumping the $1s_4-2p_6$ transition at 819 nm. By solving the master equation for the system, we identify this transition to be the most suitable one and can describe the measured increase in metastable population as a function of the 819-nm laser power. We calculate the previously unknown isotope shifts and hyperfine splittings of the $1s_4-2p_6$ transition in $^{81}\mathrm{Kr}$ and $^{85}\mathrm{Kr}$, and verify the results with count rate measurements. The demonstrated count-rate increase enables a corresponding decrease in the required sample sizes for $^{81}\mathrm{Kr}$ and $^{85}\mathrm{Kr}$ dating, a significant improvement for applications such as dating of ocean water and deep ice cores.

description: The objective of this paper is to evaluate the impact of government spending with the Interest Rates Equalization (IRE) policy on the economic growth of Brazilian regions. Additionally, it aims to measure the opportunity cost of the subsidy in relation to an alternative application in the transportation sector. The model, database, and software from the General Equilibrium Analysis Project of the Brazilian Economy (PAEG) are applied to the simulations. The result shows that the IRE policy provides economic growth in the Midwestern, Northeastern and Southern regions above the cost of the policy. Besides, in the Northern and Southeastern regions, there is a decrease in the GDP. For Brazil, the policy is cost-effective and offers a 34% rate of return. Furthermore, all regions benefit in terms of welfare. For the country, in terms of GDP or welfare, spending on the IRE has negative alternative rate of return when applied to the transportation sector. The IRE policy is efficient and contributes to reduce regional disparities.
Evidence in moral theory and the grounding of reflective equilbrium
Creators: name: Craimer, Avi
Publisher: name: University of British Columbia
Year: 2009

description: This work articulates and defends an evidence based account of moral epistemology called Case Evidentialism. From this account, we can explain and justify the bidirectional revision of moral judgments and moral principles that is advocated by the promising methodological doctrine called Reflective Equilibrium. The thesis begins with a survey of meta-ethics in order to find compelling views to represent the meta-ethical camps of realism, subjectivism, and non-cognitivism. I then argue that these three meta-ethical viewpoints imply a common account of moral evidence called Case Evidentialism. In this account, the contents of our moral judgments are evidentially supported without inference from another claim. In contrast, moral principles are only supported as generalizations inferred from the contents of our moral judgments. Inference from well supported moral generalizations may overrule moral judgments. Therefore, the bidirectional revision of moral principles and moral judgments advocated by Reflective Equilibrium can be grounded in Case Evidentialism. In the third chapter, I address a series of challenges to the use of moral judgments in moral theorizing which originates in the work of R.M. Hare. I argue that Case Evidentialism has a powerful response to each challenge. In Chapter 4, I look at the doctrines associated with moral particularism. Some of these doctrines imply a scepticism about moral principles that is at odds with Reflective Equilibrium and Case Evidentialism. I explain and criticize the particularist's arguments against moral principles, concluding that particularist scepticism about moral principles is unsustainable. I also show that there may nevertheless be moral theoretic insight within the particularisms arguments. Finally, in Chapter 5, I consider whether Case Evidentialism would be acceptable to advocates of Reflective Equilibrium. Although there are some differences between the methodological implications of Case Evidentialism and those of classic Reflective Equilibrium, I argue that Case Evidentialism does a better job explaining most of Reflective Equilibrium's methodological precepts than the standard interpretation. Further, those elements of Reflective Equilibrium which are not captured by Case Evidentialism are epistemologically unattractive.

description: In the North-Central Mexico, the main production area of beans in the country, a study was conducted during 2008-2009, whose objectives were to characterize the producers, determine the extent of adoption and to assess the impact of using the bean variety “Pinto Saltillo”, generated by INIFAP. The methodological approach was based on a formal interview to a sample of farmers, who were randomly selected from a population of 45,000 registered producers in the pattern of SAGARPA. The sample size was 496 elements. The questionnaire included closed and open questions by analyzing each of the responses through Frequency Analysis. Official sources were consulted for information as well as cooperatives, integrating and marketing of beans. The economic impact analysis of the use of Pinto Saltillo was made considering the increase in performance and / or sale price, and the number of hectares planted. The results indicated that 65.9% of farmers used the variety Pinto Saltillo and that there are different degrees of adoption by state: while in Durango and Chihuahua has been widespread use with rates of 93.3% and 82.8% respectively, Zacatecas recorded use of only 13.3%. The economic benefit generated by this variety released by INIFAP in northern central Mexico with 2008 prices, is approximately 934'000, 000 pesos. The adoption of Pinto Saltillo was a success in production and trade that benefits producers, traders, industrialists and consumers of beans.

description: AbstractWhen designing an effective enterprise data strategy, organizations often choose between a top-down and a bottom-up approach. Each method has its unique advantages and is suitable for various scenarios. The top-down approach begins with a high-level view of the business needs and strategic objectives, then gradually breaks down this view into detailed data structures and components. The bottom-up method, on the other hand, starts with existing data sources and systems, concentrating on specific details and progressively developing into a complete data model. Aligning the choice of approach with the organization’s strategic goals, data management needs, and existing infrastructure is paramount. In some situations, a hybrid approach that integrates both styles may be the most effective solution. Determining the right approach will be based on the unique circumstances and requirements of the organization. Combining overall strategic alignment with specific, actionable insights allows companies to develop strong, flexible, practical data frameworks that enhance decision-making and operational effectiveness.

We present efficient (size poly(n,d,log(1/ε)) for accuracy ε) quantum circuits for the Schur transform, which is the change of basis between the computational and the Schur bases. These circuits are based on efficient circuits for the Clebsch-Gordan transformation. We also present an efficient circuit for a limited version of the Schur transform in which one needs only to project onto different Schur subspaces. This second circuit is based on a generalization of phase estimation to any nonabelian finite group for which there exists a fast quantum Fourier transform.

description: This paper assesses consumers’ acceptance of nutritionally enhanced vegetables using a series of auction experiments administered to a random sample of adult consumers. Evidence suggests that consumers are willing to pay significantly more for fresh produce with labels signaling enhanced levels of antioxidants and vitamin C achieved by moving genes from within the species, as opposed to across species. However, this premium is significantly affected by diverse information treatments injected into the experiments.

description: Grain marketing arrangements in Australia have been controversial for many years. Following an account of the historical background to grain marketing, this article concentrates on more recent debates. The most interesting technical economic argument concerns the validity of claims that statutory marketing authorities with export monopoly powers can obtain higher prices. The article also discusses how marketing in Australia has been affected by Commonwealth and State Government policies with respect to microeconomic reform and privatization. Although major changes appear to have been made in grain marketing and its institutions, there are inherent economic problems with the current approach to deregulation.

description: I test the level of information regarding possible groundwater contamination in the residential real estate market in Washington County, Minnesota. An approximately seven square-mile trichloroethylene plume has affected hundreds of households’ water supplies since at least 1988 in the region. I find that homeowners were initially well-informed by market forces, but were later somewhat misinformed by government actions regarding the potential of water contamination from the plume. A disclosure law passed in 2003 may have added new, low-cost, and imperfect information to the market that could explain the change in informational awareness.

description: Randall (1994) argued that the Travel Cost Method (TCM) cannot generate monetary measures of recreation site benefits for use in Cost Benefit Analysis. Randall argues that what is relevant to recreational decision‐making is the subjective, and unobservable, price of travel, whereas TCM uses the observer‐assessed cost of travel. Hence, TCM can at best give ordinally measurable welfare estimates. ‘Randall’s Difficulty’ is formulated as an estimation problem and results are derived for that problem. The meaning of, prospects for, and usefulness of ordinal measurement are explored, and the existence of a solution to Randall’s Difficulty is considered.

description: In this article, we provide a comparative analysis of the industry, communication, and research infrastructure among the GCC member states as measured by the United Nations sustainable development goal 9. SDG 9 provides a clear framework for measuring the performance of nations in achieving sustainable industrialization. Three pillars of this goal are defined as quality logistics and efficient transportation, availability of mobile-cellular network with high-speed internet access, and quality research output. Based on the data from both the United Nations' SDG database and the Bertelsmann Stiftung SDG-index, our results suggest that while most of the sub-goals in SDG 9 are achieved, significant challenges remain ahead. Notably, the research output of the GCC member states is not in par with that of the developed world. We suggest the GCC decisionmakers initiate national and supranational research schemes in order to boost research and development in the region.

description: It is important to understand tradeoffs in preferences for natural and constructed green space in semi-arid urban areas because these lands compete for scarce water resources. We perform a hedonic study using high resolution, remotely-sensed vegetation indices and house sales records. We find that homebuyers in the study area prefer greener lots, greener neighborhoods, and greener nearby riparian corridors, and they pay premiums for proximity to green space amenities. The findings have fundamental implications for the efficient allocation of limited water supplies between different types of green space and for native vegetation conservation in semi-arid metropolitan areas.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Associating gamma-ray sources to their low-energy counterparts is one of the major challenges of modern gamma-ray astronomy. In the context of the Fourth Fermi Large Area Telescope Source Catalog (4FGL), the associations rely mainly on parameters as apparent magnitude, integrated flux, and angular separation between the gamma-ray source and its low-energy candidate counterpart. In this work we propose a new use of likelihood ratio and a complementary supervised learning technique to associate gamma-ray blazars in 4FGL, based only on spectral parameters as gamma-ray photon index, mid-infrared colors and radio-loudness. In the likelihood ratio approach, we crossmatch the WISE Blazar-Like Radio-Loud Sources catalog with 4FGL and compare the resulting candidate counterparts with the sources listed in the gamma-ray blazar locus to compute an association probability for 1138 counterparts. In the supervised learning approach, we train a random forest algorithm with 869 high confidence blazar associations and 711 fake associations, and then compute an association probability for 1311 candidate counterparts. A list with all 4FGL blazar candidates of uncertain type associated by our method is provided to guide future optical spectroscopic follow up observations.

description: Private R&D is a major source of innovation and productivity growth in agriculture worldwide. This paper examines trends and determinants of agricultural R&D in China. Results show that while the public sector monopolized agricultural research until recently, private agricultural R&D has grown rapidly since 2000, driven largely by agribusiness privatization. Public-sector R&D investments in basic research also encouraged private R&D research, but public investments in technology development crowded out private R&D investment. China’s private R&D investment would grow more rapidly if the government shifted public resources from technology development to basic research.

description: The identification of the constrained dynamics of mechanical systems is often challenging. Learning methods promise to ease an analytical analysis, but require considerable amounts of data for training. We propose to combine insights from analytical mechanics with Gaussian process regression to improve the model's data efficiency and constraint integrity. The result is a Gaussian process model that incorporates a priori constraint knowledge such that its predictions adhere to Gauss' principle of least constraint. In return, predictions of the system's acceleration naturally respect potentially non-ideal (non-)holonomic equality constraints. As corollary results, our model enables to infer the acceleration of the unconstrained system from data of the constrained system and enables knowledge transfer between differing constraint configurations.

description: This paper proposes a consideration on an experience of access to land developed in Zona da Mata region, Minas Gerais state, since the 80’s by familiar farmers, a Labor Union of Farmers and a Non-Governmental Organization that were acting in the area. The research used qualitative methodology and it was developed in three stages that allowed the reconstruction of the experience trajectory by means of documents and interviews with technicians, farmers, agriculture workers, and also with some people that did not participate, but followed the process at distance. The experience, named “Conquest of lands”, made possible to farmers and agriculture workers the acquirement of a piece of land by using loans made among the farmers and also from a rotational fund (created in the 90’s) with this purpose. The idea of accesses does not restrict itself to property, but also includes the development of alternative forms of production (agroecology), strengthening of farmers and agriculture workers organization, the valuation of agriculture workers know-how, and the active insertion of them in the market and in local politics. The experience involved directly until 2006 110 families that had access to 489 ha of land. In the “conquest of lands”, the fight is not only for the acquirement of a piece of land, but for the search for creation and consolidation of dignified conditions of life from the land exploring according to alternative practices of production and organization.
