description: This report provides estimates of the contribution North Dakota's cooperatives make to the state economy. A survey was used to obtain information about cooperatives' expenditures to entities within the state during the year 2000; a total of 137 usable surveys were obtained. The North Dakota Input-Output Model was used to analyze the economic contribution of the cooperatives to the state. The results indicated that the cooperatives' direct in-state expenditures totaled $1.6 billion in 2000. The largest expenditure category was the household sector, which comprised payroll, patronage refunds, and stock retirement and accounted for 46 percent of total direct expenditures. Through the multiplier process, the initial $1.6 billion of direct impacts were estimated to lead to another $3.6 billion in secondary impacts, for a total economic contribution of $5.2 billion. Cooperative activities resulted in $1.9 billion of additional personal income and $1.2 billion of retail trade activity. These levels of economic activity were associated with more than $88 million in added state tax revenues. The cooperatives employed more than 9,000 full-time and 3,000 part-time workers, and the secondary economic effects resulting from their activities resulted in more than 42,000 secondary jobs in other sectors of the state economy.
Perceptions of literary opinion in Don Quijote de la Mancha
Creators: name: Louis, Harry
Publisher: name: University of British Columbia
Year: 2009

description: The thesis is based on the premise that an author who provides expressions of literary opinion by the characters in his fictional work will also include his own views among the others—explicitly, vicariously, or by demonstration. In Don Quixote, the purported attack on books of chivalry and the inclusion of poems and stories in variant styles provide justification for extensive commentaries on literary themes. To distinguish Cervantes' views among the diverse literary opinions expressed, such commentaries are evaluated on the basis of the information provided by the author as to the background and interests of the speakers— the characters, chronicler or narrator. Specific qualities carmended, condemned, or demonstrated are identified. Stories and serious poems inserted in the novel, and literary comment in Cervantes' Galatea and Viaje del Pamaso, are examined for corroboration or contradiction of the findings. Relevant opinions of several generations of twentieth-century critics are examined. Conclusions summarize—for Fiction, Poetry and Drama—the features which satisfy the stated requirement to "delight and instruct" and those to be avoided. A degree of ambivalence, between certain literary precepts which Cervantes promotes in Don Quixote and those demonstrated in his work, is identified. Special requirements for History are noted. Whether or not, under the respectable guise of an attack on books of chivalry, Cervantes sought to elevate the public taste in literature—an endeavour as quixotic as any undertaken by his protagonist—he claimed due recognition from the literary world for his perceptions of literary values and his competence as a writer.

description: The possibility that nuclear matter at a density relevant to the interior of massive neutron stars may be a quarkynoic matter has attracted considerable recent interest. In this work, we construct a field theoretical model to describe the quarkyonic matter, that would allow quantitative and systematic calculations of its various properties. This is implemented by synthesizing the Walecka model together with the quark-meson model, where both quark and nucleon degrees of freedom are present based on the quarkyonic scenario. With this model we compute at mean-field level the thermodynamic properties of the symmetric nuclear matter and calibrate model parameters through well-known nuclear physics measurements. We find this model gives a very good description of the symmetric nuclear matter from moderate to high baryon density and demonstrates a continuous transition from nucleon-dominance to quark-dominance for the system.
Dealing with Inaccurate and Incomplete Labels in Industrial Streaming Data

Publisher: name: Universität Bielefeld

Subjects: subject: 004

description: The pressure to increase the energetic eﬃciency of industrial facilities has led to a strong
increase in the number of installed measurement sensors. These collect large volumes
of data that need to be processed and analyzed. As manual data processing methods are
not appropriate due to the sheer amount of data, automated and intelligent solutions are
needed. Machine learning techniques are a viable option for processing large volumes
of data and are capable to capture complex relationships within it. However, obtaining
meaningfully annotated data is a real challenge and typically incurs large costs. Especially,
in an industrial setting where the generic data type is streaming data which is constantly
evolving. Thus, devising machine learning models which are able to perform a desired task
in industrial environments with few labelled data samples and drifting data features poses a
severe challenge. In this thesis, we will address two main technical challenges in the ﬁeld of
analyzing industrial streaming data: (1) how to eﬃciently train models with only partially
labeled data, and (2) how to train models when a sizable fraction of the label information
is not correct or is changing over time. We propose several strategies how to deal with
these questions and evaluate their performance on stationary and non-stationary benchmark
data sets, as well as real-world industrial application data. As one central aspect of the
approaches, we propose to use constrained embedding representations for the raw input
data. These representations are shown to be eﬃcient for dealing with limited annotated
data by analysis of the labeled and unlabeled data based on similarities in the embedding
space. They allow for robust semi-supervised training of deep neural networks in the
presence of label noise, and even gradually correct the mislabeled samples during training.
Similarly, connecting these latent representations to a network performing predeﬁned tasks
is shown to be useful for accurate concept drift detection. Another core aspect of these
approaches is their capability to handle sparsely labeled data in streaming environments.
By propagating the available labels to unlabeled samples, based on their proximity in the
embedding space and the time of arrival of the labels, we can successfully train accurate
models with incomplete and delayed labels in resource-constrained settings. Our work
shows that the proposed methods are very eﬀective for analyzing streaming data with sparse
and even incorrect or delayed labels, as well as concept drift. We apply our methods in
real-world industrial data in diﬀerent tasks, such as robust anomaly detection with few
labeled samples, predictive modeling of industrial machinery with presence of label noise
and delayed labels, and also semi-supervised concept drift detection.

description: Recovering a signal from auto-correlations or, equivalently, retrieving the phase linked to a given Fourier modulus, is a wide-spread problem in imaging. This problem has been tackled in a number of experimental situations, from optical microscopy to adaptive astronomy, making use of assumptions based on constraints and prior information about the recovered object. In a similar fashion, deconvolution is another common problem in imaging, in particular within the optical community, allowing high-resolution reconstruction of blurred images. Here we address the mixed problem of performing the auto-correlation inversion while, at the same time, deconvolving its current estimation. To this end, we propose an I-divergence optimization, driving our formalism into a widely used iterative scheme, inspired by Bayesian-based approaches. We demonstrate the method recovering the signal from blurred auto-correlations, further analysing the cases of blurred objects and band-limited Fourier measurements.

description: This study focuses on the possible impact of the MFA phase-out on the world economy. Starting from analyzing trends in world textile and apparel trade (T&A), the study found that the developing countries were a growing factor in world T&A trade in recent decades. Moreover, using trade data from 91 countries over 37 years, the empirically investigate of the study indicates a strong positive relationship between trade in textile and apparel and the standard of living. However, about 50 percent of industrial countries’ markets are not available for developing countries and intra-EU trade still accounts for half of total EU imports of T&A products. A more open and freer market in the industrial countries is an important condition for developing countries to maintain their growth momentum. The study further focuses on the possible impacts of the MFA phase-out on the world T&A trade using an intertemporal, global general equilibrium model. The study found that the MFA phase-out would enlarge world trade of T&A and developing countries will further gain market share in world total exports. Almost all countries, including both the developing countries restrained by the MFA quotas and free from the MFA quotas, and the industrial countries, gain in term of social welfare post- MFA in the model. Even though the developing countries currently free from the MFA quota restrains may lose their market shares, as world T&A prices are lowered by improving the efficiency of world T&A trade post-MFA, consumers are better off by consuming cheap commodities.

description: Computable General Equilibrium (CGE) models are a class of economywide models that are widely used for policy analysis in developing countries. This paper provides a detailed documentation of an applied CGE model of Malawi  the first ever for Malawi  developed in the context of the project Collaborative Research and Capacity Strengthening for Multi-Sector Policy Analysis in Malawi and Southern Africa. The purpose of this paper is to serve as a source of background information for analysts using the model in the context of the current project and in the future. The model is built around a 1998 Social Accounting Matrix (SAM) for Malawi, which was developed in the context of the current project, is based on data from the 1998 Integrated Household Survey of Malawi. The main parts of the paper are a brief, self-contained summary of the model, and a detailed mathematical model statement, presented in a step-by-step fashion. The Appendices present a mathematical model statement in summary form and the 1998 Malawi SAM. The applied Malawi model can be used for analyses in a relatively wide range of areas, including agricultural, trade, and tax and subsidy policies. It is characterized by a detailed treatment of the labor market and households, permitting model simulations to generate information about the disaggregated impact of policies on household welfare. As part of the project research activities, the model is used to analyze the impact of external shocks and domestic policies aimed at poverty alleviation. This analysis is presented in a separate document.

description: The arboricity of a graph is the minimum number of forests required to cover all its edges. In this paper, we examine arboricity from a game-theoretic perspective and investigate cost-sharing in the minimum forest cover problem. We introduce the arboricity game as a cooperative cost game defined on a graph. The players are edges, and the cost of each coalition is the arboricity of the subgraph induced by the coalition. We study properties of the core and propose an efficient algorithm for computing the nucleolus when the core is not empty. In order to compute the nucleolus in the core, we introduce the prime partition which is built on the densest subgraph lattice. The prime partition decomposes the edge set of a graph into a partially ordered set defined from minimal densest minors and their invariant precedence relation. Moreover, edges from the same partition always have the same value in a core allocation. Consequently, when the core is not empty, the prime partition significantly reduces the number of variables and constraints required in the linear programs of Maschler's scheme and allows us to compute the nucleolus in polynomial time. Besides, the prime partition provides a graph decomposition analogous to the celebrated core decomposition and the density-friendly decomposition, which may be of independent interest.

description: We propose to develop a high-energy heavy-ion experimental database and make it accessible to the scientific community through an on-line interface. This database will be searchable and cross-indexed with relevant publications, including published detector descriptions. Since this database will be a community resource, it requires the high-energy nuclear physics community's financial and manpower support. This database should eventually contain all published data from Bevalac, AGS and SPS to RHIC and LHC energies, proton-proton to nucleus-nucleus collisions as well as other relevant systems, and all measured observables. Such a database would have tremendous scientific payoff as it makes systematic studies easier and allows simpler benchmarking of theoretical models to a broad range of old and new experiments. Furthermore, there is a growing need for compilations of high-energy nuclear data for applications including stockpile stewardship, technology development for inertial confinement fusion and target and source development for upcoming facilities such as the Next Linear Collider. To enhance the utility of this database, we propose periodically performing evaluations of the data and summarizing the results in topical reviews.

LESS POVERTY IN EGYPT? EXPLORATIONS OF ALTERNATIVE PASTS WITH LESSONS FOR THE FUTURE

Publisher: name: Unknown
Year: 2001
Subjects: Food Security and Poverty

description: In this paper, the impact of alternative development strategies on growth and poverty is assessed in an economywide framework, using Egypt as a case study. The analysis is guided by the following question: By pursuing a development strategy different from the one actually pursued since the late 1970s, could Egypt’s government significantly have improved the status of its poor? To address this question, a dynamic, recursive, Computable General Equilibrium (CGE) model is used to simulate Egypt’s economy for the period 1979-1997. The model is built around a Social Accounting Matrix (SAM) for 1979. The base scenario incorporates Egypt’s evolving policy regime and changes in Egypt’s external environment, including a gradual transition toward an economy with less government involvement. The other scenarios differ in terms of trade policies, domestic incentives, asset distribution, and the pattern of domestic productivity growth. The results indicate that pro-poor redistribution of land and human capital assets could have been a particularly effective tool had Egypt prioritized more strongly to improve the welfare of the poor and reduce inequalities. Such policies could have been implemented without any noticeable negative impact on growth or aggregate welfare. The results also suggest that, for Egypt, there was no contradiction between more rapid growth, largely a function of more rapid productivity growth, and improved welfare for the poor. The impact of more rapid reduction of price distortions, induced by taxes and subsidies, is small but positive in terms of aggregate growth. The effects of introducing biases in favor of specific sectors may be stronger and depend on the specific context, including the nature of economic linkages and, with regard to the policies analyzed in this paper, on the ease with which it is possible to raise productivity growth, reduce transactions costs, and get improved access to export markets. The present analysis confirms the finding of earlier analyses that, compared to pro-manufacturing policies, pro-agricultural policies have a more positive impact on household welfare in general and the poor in particular. There is a significant synergy between a pro-agricultural shift in productivity growth, improved market access for agricultural exports, and reduced transactions costs in foreign trade.
Suburban water flows
Creators: name: Labrie, Michel Rene
Publisher: name: University of British Columbia
Year: 2009

description: Typical suburban housing water cycle practices are polluting the natural water cycle and contributing to the degradation of watersheds. This thesis defines and applies a process that prioritises strategies for transformation of existing suburban housing water cycle into an ecologically sensitive on-site water cycle. An existing typical suburban block located in Brentwood Bay, British Columbia is used as a primary vehicle for this investigation. The process is composed of two distinct sections: assessment and transformation. The assessment section consists of two principal objectives: assessing existing conditions and prioritising strategies for transformation. The transformation section consists of four objectives prioritised as follows: first, eliminating on-site degradation; second, reducing the water demand; third, treating and using wastewater; and fourth, collecting and using rainwater. This thesis exclusively examines on-site flow management strategies in order to efficiently and appropriately transform the existing conditions. Social, political, and economic strategies are not studied in this thesis. This research acknowledges the importance of respecting on-site ecological requirements in order to avoid on-site degradation during suburban housing operation. This thesis suggests that it is possible to address the Brentwood Bay suburban housing water cycle on-site with no impact on the host watershed. Furthermore, it is possible to significantly densify the existing site conditions while avoiding degradation of the host watershed. Given the generic nature of the process, it can be readily applied to other climates, building types, and scales. The process can also be applied to both existing retrofit and new construction. The application of the thesis process facilitates the elimination of on-site degradation, the reduction of municipal loading and the increase of natural on-site water cycle carrying capacity.

description: Exploring exotic interface magnetism due to charge transfer and strong spin-orbit coupling has profound application in future development of spintronic memory. Here, the emergence, tuning and interpretation of hump-shape Hall Effect from a CaMnO3/CaIrO3/CaMnO3 trilayer structure are studied in detail. The hump signal can be recognized as Topological Hall Effect suggesting the presence of Skyrmion-like magnetic bubbles; but the debated alternative interpretation where the signal being an artefact between two cancelling Anomalous Hall Effect loops is also discussed. Firstly, by tilting the magnetic field direction, the evolution of Hall signal suggests transformation of the bubbles topology into a more trivial kind. Secondly, by varying the thickness of CaMnO3, the optimal thicknesses for the hump signal emergence are found, suggesting a tuning of charge transfer fraction. Using high-resolution transmission electron microscopy, a stacking fault is also identified, which distinguishes the top and bottom CaMnO3/CaIrO3 interfaces in terms of charge transfer fraction and possible interfacial Dzyaloshinskii-Moriya Interaction. Finally, a spin-transfer torque experiment revealed a low threshold current density of ~10^9 A/m^2 for initiating the motion of bubbles. This discovery opens a possible route for integrating Skyrmions with antiferromagnetic spintronics.

description: Les théories linguistiques de Nikolaj Marr ont profondément imprégné la vie intellectuelle soviétique jusque dans les années 1950. Ce succès s’explique à la fois par une série de facteurs conjoncturels et par la personnalité même du savant géorgien. En plus d’une chronologie périodisée de l’évolution du « marrisme », il est possible de distinguer des fils de trame invariants, qui depuis ses débuts sous-tendent son développement. L’étude des ethnonymes et des toponymes constituait pour Marr un terrain de prédilection, où ont germé bon nombre de ses idées en linguistique générale. Malgré l’abandon officiel de ses thèses et le discrédit qui subsiste toujours à leur sujet, il faut constater leur permanence dans les travaux de certains kartvélologues, singulièrement sur le plan de l’étymologie des ethno- et toponymes. Ce recours aux théories de Marr est scientifiquement critiquable, mais il importe surtout d’en comprendre les raisons afin d’éclairer le regard porté par ces chercheurs sur la place de la Géorgie dans le monde.

We estimate the possible flux in a way that does not depend on detailed assumptions about the density profiles of dark matter clumps. The result confirms that collisional annihilation is compatible with annihilation cross sections below the unitarity bounds for superheavy dark matter if the particles can form dense cores in dark matter substructure, and it provides estimates for core sizes and densities. The ensuing clumpy source distribution in the galactic halo will be tested within a few years of operation of the Pierre Auger observatory.

description: An important component of the current debate about agriculture trade negotiations is whether further liberalization of trade and agricultural policies may help or hinder food security in WTO member countries. These concerns were formulated first, in Article 20 of the Agreement on Agriculture negotiated during the Uruguay Round, which indicated that negotiations should take into consideration, among other things, "non trade concerns"; and in its preamble, which mentioned as examples of those concerns, "food security and the need to protect the environment". They were also reaffirmed in the Doha Declaration, which declares that "the long-term objective" is "to establish a fair and market-oriented trading system through a program of fundamental reform", and confirmed that special and differential treatment will be granted to developing countries "to effectively take account of their development needs, including food security and rural development". Although the issue of food security and agricultural negotiations within the WTO has been raised both by industrialized ("multifunctionality" of agriculture) and developing countries, the discussion in the case of developing countries has included important policy objectives such as elimination of poverty and hunger (as cause and consequence of food insecurity). Concerned with the effects that further negotiations would have on the attainment of those objectives in poor countries, several developing countries have proposed the creation of a "Development Box" or a "Food Security Box". To contribute to this debate, the paper surveys and discusses in greater detail three main aspects of trade liberalization and food security within the WTO: the adequacy of the current WTO classification of countries according to their food security situation; the policy perspectives in industrialized countries and in developing countries; and the legal issues faced by developing countries. The paper concludes that a better classification is needed within the WTO to target food insecure countries, that many food security concerns can be addressed with specific clarifications and changes in the current language of the AoA, and that although developing countries may not be legally constrained to invest in food security, they lack the financial, human, and institutional resources to do so.

description: This paper reviews the experience of the use of computable or applied general equilibrium (CGE or AGE) models to affect public policy. The range of issues on which CGE models have had an influence is quite wide, and includes structural adjustment policies, international trade, public finance, agriculture, income distribution, and energy and environmental policy. In the cases where CGE models have enlightened the policy debate, the reasons have to do with one or more of the following: (i) consistency between results from CGE models and other types of analysis (for instance in the debate on NAFTA); (ii) the fact that the CGE models captured particular features of the economy, such as some structural rigidities and institutional constraints, that rules of thumb, based on simpler analysis failed to capture; or (iii) CGE models provided a consistent framework to assess the linkages and tradeoffs among different policy packages. We also consider misuses of CGE models in policy debates. Most of these stem from: (i) pushing the model beyond its domain of applicability; (ii) violating the principle of Occam.s razor.use the simplest model suited to the task; (iii) the black box syndrome.results whose link with the policy change is opaque. In assessing the use of models in policy, it is important to distinguish between stylized and applied models. Both have been used in policy debates, but there are important differences in their uses, particularly in their domain of applicability. Stylized models tend to be small, narrowly focused, and emphasize a particular causal chain or policy. Applied models are usually larger, seek to capture important institutional characteristics of the economy being modeled, and encompass a wider spectrum of issues; but they are vulnerable to the black-box syndrome and violation of Occam.s razor. Complementary use of stylized and applied CGE models has enhanced the effectiveness of both in policy debates.

description: Interpreting spectropolarimetric observations of the solar atmosphere takes much longer than the acquiring the data. The most important reason for this is that the model fitting, or "inversion", used to infer physical quantities from the observations is extremely slow, because the underlying models are numerically demanding. We aim to improve the speed of the inference by using a neural network that relates input polarized spectra to the output physical parameters. We first select a subset of the data to be interpreted and infer physical quantities from corresponding spectra using a standard minimization-based inversion code. Taking these results as reliable and representative of the whole data set, we train a convolutional neural network to connect the input polarized spectra to the output physical parameters (nodes, in context of spectropolarimetric inversion). We then apply the neural network to the various other data, previously unseen to the network. As a check, we apply the referent inversion code to the unseen data and compare the fit quality and the maps of the inferred parameters between the two inversions. The physical parameters inferred by the neural network show excellent agreement with the results from the inversion, and are obtained in a factor of $10^5$ less time. Additionally, substituting the results of the neural network back in the forward model, shows excellent agreement between inferred and original spectra. The method we present here is very simple for implementation and extremely fast. It only requires a training data set, which can be obtained by inverting a representative subset of the observed data. Applying these (and similar) machine learning techniques will yield orders of magnitude acceleration in the routine interpretation of spectropolarimetric data.

We specifically address the question of how to combine the approach which sums all leading logarithms in Q/Q_0 (where Q is the jet transverse momentum) with the BFKL approach, in which leading logarithms of the scattering energy are summed. Using an "all orders" matching, we obtain results for the cross section which correctly reproduce the two approaches in the appropriate limits.

description: There is widespread agreement on the need for land reform in Zimbabwe as a means of reducing poverty. This paper assesses the potential consequences of a land-reform scheme that draws on proposals from Zimbabwe’s government in 1998 and 1999. We analyze the impact of the reform on resettled farm households and as a development project for which we conduct cost-benefit analysis. The analysis, which considers costs and benefits during a 15-year period, relies on a set of models of family farms that are typical of those that would benefit from land redistribution. The cost-benefit analysis is more comprehensive, also considering the different costs and benefits that affect the government. The results of our analysis indicate that a government-supported land reform could be economically viable under what we consider as realistic assumptions regarding the performance of the beneficiaries and the costs that will be faced by the government and other stakeholders. Land reform can generate sustainable livelihoods for the beneficiaries. If viewed as a project, the NPV of the reform is positive for a discount rate that is as high as 20%. The project can also increase employment in the agricultural sector. The analysis takes a long-run perspective, covering a 15-year period. During the first resettlement years, some disruption of agricultural production should be expected. These results are preliminary and based on a partial equilibrium perspective. They are driven by the assumption that the land reform is carried out in a manner that allows farmers on the resettled lands to achieve their productive potential. Such an outcome depends critically on the assumption that the farmers are able to operate in an enabling environment, including critical government support, especially during years 1-5.

description: In this paper, a susceptible-infected-removed (SIR) model has been used to track the evolution of the spread of the COVID-19 virus in four countries of interest. In particular, the epidemic model, that depends on some basic characteristics, has been applied to model the time evolution of the disease in Italy, India, South Korea and Iran. The economic, social and health consequences of the spread of the virus have been cataclysmic. Hence, it is essential that available mathematical models can be developed and used for the comparison to be made between published data sets and model predictions. The predictions estimated from the SIR model here, can be used in both the qualitative and quantitative analysis of the spread. It gives an insight into the spread of the virus that the published data alone cannot do by updating them and the model on a daily basis. For example, it is possible to detect the early onset of a spike in infections or the development of a second wave using our modeling approach. We considered data from March to June, 2020, when different communities are severely affected. We demonstrate predictions depending on the model's parameters related to the spread of COVID-19 until September 2020. By comparing the published data and model results, we conclude that in this way, it may be possible to better reflect the success or failure of the adequate measures implemented by governments and individuals to mitigate and control the current pandemic.

description: RV variable stars are important in astrophysics. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) spectroscopic survey has provided ~ 6.5 million stellar spectra in its Data Release 4 (DR4). During the survey, ~ 4.7 million unique sources were targeted and ~ 1 million stars observed repeatedly. The probabilities of stars being RV variables are estimated by comparing the observed radial velocity variations with the simulated ones. We build a catalog of 80,702 RV variable candidates with probability greater than 0.60 by analyzing the duplicate-observed multi-epoch sources covered by the LAMOST DR4. Simulations and cross-identifications show that the purity of the catalog is higher than 80%. The catalog consists of 77% binary systems and 7% pulsating stars as well as 16% pollution by single stars. 3,138 RV variables are classified through cross-identifications with published results in literatures. By using the 3,138 sources common to both LAMOST and a collection of published RV variable catalogs we are able to analyze LAMOST's RV variable detection rate. The efficiency of the method adopted in this work relies not only on the sampling frequency of observations but also periods and amplitudes of RV variables. With the progress of LAMOST, Gaia and other surveys, more and more RV variables would will be confirmed and classified. This catalog is valuable for other large-scale surveys, especially for RV variable searches. The catalog will be released according to the LAMOST Data Policy via http://dr4.lamost.org.

description: This analysis examines the implications of WTO accession for China’s domestic policies and institutions by identifying some of Chinese agricultural policies and institutional arrangements that may generate conflicts with WTO requirements and analyzing the nature and extent of the conflict that may be introduced by WTO accession. We differentiate three alternative ways that China’s current domestic policy or institutions may conflict with or be incompatible with WTO accession: (1) the domestic policy or institution is expressly prohibited by WTO rules and principles; (2) the changes required by WTO accession impose additional costs on the government such that the existing policy or institutions are difficult to sustain; and (3) the changes required for WTO accession reduce the effectiveness of the policies or institutions. Based only on the incomplete information currently available on China’s WTO commitments, we suggest that the greatest conflicts center on China’s policies that manage agricultural supply, distribution, and trade of major commodities. First, China’s state trading enterprises will no longer have a monopoly on trade. This is likely to reduce the government’s ability to use STE as a policy instrument to limit imports in order to support domestic production. Second, the most important conflict with China’s WTO commitment is likely to be China’s use of a state-run monopoly procurement system for grains and cotton. This change will diminish the government’s current policy goal of managing supply and distribution of key agricultural commodities. The impact on farmers, however, is likely to be mixed and will be influenced by general agricultural supply and demand conditions. Third, the change in China’s import tariff duties is not expected to have a significant impact on either domestic policy or on government revenues. However, in terms of domestic support, China will face a conflict in the operation of its grain stockholding policy, while the large number of government programs that meet the WTO “Green Box” criteria will be increasingly important to China’s agriculture. In this way, China’s farmers will hopefully be able to reduce costs, increase yields, and improve their competitiveness.

description: Recently, a series of dedicated inverse-kinematics experiments performed at GSI, Darmstadt, has brought an important progress in our understanding of proton and heavy-ion induced reactions at relativistic energies. The nuclear reaction code ABRABLA that has been developed and benchmarked against the results of these experiments has been used to calculate nuclide production cross sections at different energies and with different targets and beams. These calculations are used to estimate nuclide production rates by protons in thick targets, taking into account the energy loss and the attenuation of the proton beam in the target, as well as the low-energy fission induced by the secondary neutrons. The results are compared to the yields of isotopes of various elements obtained from different targets at CERN-ISOLDE with 600 MeV protons, and the overall extraction efficiencies are deduced. The dependence of these extraction efficiencies on the nuclide half-life is found to follow a simple pattern in many different cases. A simple function is proposed to parameterize this behavior in a way that quantifies the essential properties of the extraction efficiency for the element and the target - ion-source system in question.
