description: This paper presents a Multi-Agent System (MAS) approach for designing an air pollution simulator. The aim is to simulate the concentration of air pollutants emitted from sources (e.g. factories) and to investigate the emergence of cooperation between the emission source managers and the impact this has on air quality. The emission sources are controlled by agents. The agents try to achieve their goals (i.e. increase production, which has the side effect of raising air pollution) and also cooperate with others agents by altering their emission rate according to the air quality. The agents play an adapted version of the evolutionary N-Person Prisoners' Dilemma game in a non-deterministic environment; they have two decisions: decrease or increase the emission. The rewards/penalties are influenced by the pollutant concentration which is, in turn, determined using climatic parameters. In order to give predictions about the Plume Dispersion) model and an ANN (Artificial Neural Network) prediction model. The prediction is calculated using the dispersal information and real data about climatic parameters (wind speed, humidity, temperature and rainfall). Every agent cooperates with its neighbours that emit the same pollutant, and it learns how to adapt its strategy to gain more reward. When the pollution level exceeds the maximum allowed level, agents are penalised according to their participation. The system has been tested using real data from the region of Annaba (North-East Algeria). It helped to investigate how the regulations enhance the cooperation and may help controlling the air quality. The designed system helps the environmental agencies to assess their air pollution controlling policies.

description: The electrosurgical technology category is used widely, with a diverse spectrum of devices designed for different surgical needs. Historically, hospitals are supplied with electrosurgical devices from several manufacturers, and those devices are often evaluated separately; it may be more efficient to evaluate the category holistically. This study assessed the health economic impact of adopting an electrosurgical device-category from a single manufacturer. A budget impact model was developed from a U.S. hospital perspective. The uptake of electrosurgical devices from EES (Ethicon Electrosurgery), including ultrasonic, advanced bipolar, smoke evacuators, and reusable dispersive electrodes were compared with similar MED (Medical Energy Devices) from multiple manufacturers. It was assumed that an average hospital performed 10,000 annual procedures 80% of which involved electrosurgery. Current utilization assumed 100% MED use, including advanced energy, conventional smoke mitigation options (e.g. ventilation, masks), and single-use disposable dispersive electrode devices. Future utilization assumed 100% EES use, including advanced energy devices, smoke evacuators (i.e. 80% uptake), and reusable dispersive electrodes. Surgical specialties included colorectal, bariatric, gynecology, thoracic and general surgery. Systematic reviews, network meta-analyses, and meta-regressions informed operating room (OR) time, hospital stay, and transfusion model inputs. Costs were assigned to model parameters, and price parity was assumed for advanced energy devices. The costs of disposables for dispersive electrodes and smoke-evacuators were included. The base-case analysis, which assessed the adoption of EES instead of MED for an average U.S. hospital predicted an annual savings of $824,760 ($101 per procedure). Savings were attributable to associated reductions with EES in OR time, days of hospital stay, and volume of disposable electrodes. Sensitivity analyses were consistent with these base-case findings. Category-wide adoption of electrosurgical devices from a single manufacturer demonstrated economic advantages compared with disaggregated product uptake. Future research should focus on informing comparisons of innovative electrosurgical devices.

description: We calculate the inclusive production of a polarized $Λ$ or $\barΛ$ hyperon from the single longitudinally polarized proton and proton ($pp$) collision at RHIC. By comparing the data reported by the STAR Collaboration, we find that this process is sensitive to the polarization of strange and antistrange quarks of the proton in the experimental range. By introducing asymmetric coefficients with the minimization of $χ^2$, we further identify the asymmetry of the polarized strange-antistrange quarks in the proton sea and find that the first moment is $Δs \approx -0.025\pm 0.019$ for strange quark and $Δ\bar s \approx -0.001\pm 0.012$ for antistrange quark, with central values agreeing with the light-cone meson-baryon fluctuation model prediction, the recent lattice QCD determination of strangeness polarization and results from a global QCD analysis given by the Jefferson Lab Angular Momentum (JAM) Collaboration.

description: Administrative agencies in the United States receive millions of comments each year concerning proposed agency actions during the eRulemaking process. These comments represent a diversity of arguments in support and opposition of the proposals. While agencies are required to identify and respond to substantive comments, they have struggled to keep pace with the volume of information. In this work we address the tasks of identifying argumentative text, classifying the type of argument claims employed, and determining the stance of the comment. First, we propose a taxonomy of argument claims based on an analysis of thousands of rules and millions of comments. Second, we collect and semi-automatically bootstrap annotations to create a dataset of millions of sentences with argument claim type annotation at the sentence level. Third, we build a system for automatically determining argumentative spans and claim type using our proposed taxonomy in a hierarchical classification model.

description: We study the existence of densities for distributions of piecewise deterministic Markov processes. We also obtain relationships between invariant densities of the continuous time process and that of the process observed at jump times. In our approach we use functional-analytic methods and the theory of linear operator semigroups. By imposing general conditions on the characteristics of a given Markov process, we show the existence of a substochastic semigroup describing the evolution of densities for the process and we identify its generator. Our main tool is a new perturbation theorem for substochastic semigroups, where we perturb both the action of the generator and of its domain, allowing to treat general transport-type equations with non-local boundary conditions. A couple of particular examples illustrate our general results.

description: We theoretically study radiation pressure induced generation of the frequency components at the sum sideband in an optomechanical system containing an optical parametric amplifier (OPA). It is shown that an OPA inside a cavity can considerably enhance the amplitude of sum sideband even with low power input fields. We find a new matching condition for the upper sum sideband generation. The height and width of the new peak can be adjusted by the nonlinear gain of the OPA. Furthermore, the lower sum sideband generation can be enhanced with several orders of magnitude by tuning the nonlinear gain parameter and the phase of the field pumping the OPA. The enhanced sum sideband may have potential applications to the manipulation of light in a on-chip optomechanical device and the sensitively sensing for precision measurement in the weak optomechanical coupling regime.

The economic aspects of fertiliser distribution in East Java (Indonesia)
Creators: name: Sjafradji, Saleh
Publisher: name: The Australian National University
Year: 1976
Subjects: subject: Fertilizers Prices Indonesia Java
subject: Rice Indonesia Java

description: Self-sufficiency in rice production was set as a policy goal in the First Five Year Plan of Indonesia, 1969-1973 (REPELITA I). Incentives to increase rice production are not provided by increasing the price of rice, since the Indonesian Government believes that this would have a destabilising effect on the economy as a whole. Instead, farmers are encouraged to increase rice production through the subsidisation of input prices, particularly manufactured fertiliser prices, under the Bimas/Inmas scheme. However, the subsidised price for fertiliser distributed to Bimas/ Inmas farmers creates a dualistic market for fertiliser and results in leakages from the official network to private distribution channels. In turn, this reduces the quantity of fertiliser which rice farmers receive at the subsidised price. The low distribution margins for the official network also discourage distribution services and hence reduce the flow of fertiliser with respect to both amount and timing of delivery. Thus it would appear that official distribution faces conflict in objectives: efforts to reduce the costs of fertiliser for Bimas-Inmas farmers and distributors tend to reduce or delay the quantity of fertiliser reaching the participants in the intensification schemes. The advantage to Bimas farmers of credit subsidisation may also be offset by various inefficiencies of the official distribution network, particularly with respect to procedural difficulties encountered in obtaining credit. This study examines the nature and problems of fertiliser distribution through official and private networks and proposes various hypotheses which can be tested to judge and compare the efficiency of these networks. The information required to test such hypotheses will be collected following the final draft of this dissertation.

description: Applying a bio-economic whole farm model we assess the impact of price and weather risk as well as different risk management strategies on the variability of the income in Swiss suckler cow production. We consider different on-farm risk management strategies such as the flexible adjustment of herd size, fodder composition and feed stocks, as well as an income insurance. Our results show that without any risk-management income variability is rather high, with coefficient of variation (CV) of income ranging from 26% to 31%. Taking on-farm risk management strategies into account it is possible to reduce income variability significantly (CV 12-15%), but causes only low reductions of mean income levels. Our results also indicate that income insurance is not attractive for farmers Our results thus suggest that in particular promoting better access to markets for feed stuff provides an valuable opportunities for farmers to manage income risks.
Status of four-neutrino mass schemes: a global and unified approach to current neutrino oscillation data

description: We present a unified global analysis of neutrino oscillation data within the framework of the four-neutrino mass schemes (3+1) and (2+2). We include all data from solar and atmospheric neutrino experiments, as well as information from short-baseline experiments including LSND. If we combine only solar and atmospheric neutrino data, (3+1) schemes are clearly preferred, whereas short-baseline data in combination with atmospheric data prefers (2+2) models. When combining all data in a global analysis the (3+1) mass scheme gives a slightly better fit than the (2+2) case, though all four-neutrino schemes are presently acceptable. The LSND result disfavors the three-active neutrino scenario with only $Δm^2_{sol}$ and $Δm^2_{atm}$ at 99.9% CL with respect to the four-neutrino best fit model. We perform a detailed analysis of the goodness of fit to identify which sub-set of the data is in disagreement with the best fit solution in a given mass scheme.

description: In a previous paper [Phys. Rev. D 97, 104044 (2018)] we pointed out some shortcomings of the standard approach to chameleon theories consisting in treating the small bodies used to test the weak equivalence principle (WEP) as test particles, whose presence do not modify the chameleon field configuration. In that paper we developed an alternative method to determine the relevant field configuration which takes into account the influence of both test and source bodies, and computed the chamaleon mediated force. Relying on that analysis we showed that the effective acceleration of test bodies is composition dependent even when the model is based on universal couplings. In this paper, we improve our method by using a more suitable approximation for the effective chameleon potential in situations where the bodies are in the so-called "thick shell regime". We then find new and more restrictive bounds on the model' s parametres by confronting the new theoretical predictions with the empirical bounds on Eötvös parameter comming from the lunar laser ranging experiments.

Low-Temperature Long-Time Simulations of Ising Ferromagnets using the Monte Carlo with Absorbing Markov Chains method

description: The Monte Carlo with Absorbing Markov Chains (MCAMC) method is introduced. This method is a generalization of the rejection-free method known as the $n$-fold way. The MCAMC algorithm is applied to the study of the very low-temperature properties of the lifetime of the metastable state of Ising ferromagnets. This is done both for square-lattice and cubic-lattice nearest-neighbor models. Comparison is made with exact low-temperature predictions, in particular the low-temperature predictions that the metastable lifetime is discontinuous at particular values of the field. This discontinuity for the square lattice is not seen in finite-temperatures studies. For the cubic lattice, it is shown that these `exact predictions' are incorrect near the fields where there are discontinuities. The low-temperature formula must be modified and the corrected low-temperature predictions are not discontinuous in the energy of the nucleating droplet.

description: Food prices have steadily risen since the 1990s, and price were especially volatile in the years 2008 and 2010. This trend has also been reflected in the European grain market, which presents all European companies along the food value chain with new challenges. This paper focuses on the impacts of increased price volatility on the grain market. Furthermore, it describes and evaluates government interventions attempting to reduce this volatility. At the same time, it describes and assesses private management methods of dealing with price volatility. In this article, we provide an opportunity to understand how the European cereals market evolved to reach its present state and suggest future possible price assurance systems, such as insurance for the basic monetary security of cereal products for all of the parties involved.

description: TEM has shown that the strongly piezoelectric material Pb(Zr0.52Ti0.48)O3 separates into two phases at low temperatures. The majority phase is the monoclinic phase previously found by x-ray diffraction. The minority phase, with a nanoscale coherence length, is a slightly distorted variant of the first resulting from the anti-phase rotation of the oxygen octahedra about [111]. This work clears up a recent controversy about the origin of superlattice peaks in these materials, and supports recent theoretical results predicting the coexistence of ferroelectric and rotational instabilities.

description: In this paper we use weekly milling wheat price series for nine selected EU countries to evaluate levels and components of volatility in the period from July 2004 to April 2011 and to examine how sensitive the results can be to spatial aggregation of the price data. The prices were analyzed in levels and logarithmic rate of returns. To asses price risk, apart from basic measures of price variability, the price series were decomposed using multiplicative model in order to determine shares of seasonal and random components in the total variance of the prices. We also applied ARMAX model to separate the stochastic components of the price series to properly evaluate real price risk exposure and tested for ARCH and GARCH effects. We found considerable differences when comparing various price volatility measures calculated for the analyzed countries indicating that wheat price risk exposure may vary across the EU.

description: The electrosurgical technology category is used widely, with a diverse spectrum of devices designed for different surgical needs. Historically, hospitals are supplied with electrosurgical devices from several manufacturers, and those devices are often evaluated separately; it may be more efficient to evaluate the category holistically. This study assessed the health economic impact of adopting an electrosurgical device-category from a single manufacturer. A budget impact model was developed from a U.S. hospital perspective. The uptake of electrosurgical devices from EES (Ethicon Electrosurgery), including ultrasonic, advanced bipolar, smoke evacuators, and reusable -dispersive electrodes were compared with similar MED (Medical Energy Devices) from multiple manufacturers. It was assumed that an average hospital performed 10,000 annual procedures 80% of which involved electrosurgery. Current utilization assumed 100% MED use, including advanced energy, conventional smoke mitigation options (e.g., ventilation, masks), and single-use disposable dispersive electrode devices. Future utilization assumed 100% EES use, including advanced energy devices, smoke evacuators (i.e., 80% uptake), and reusable dispersive electrodes. Surgical specialties included colorectal, bariatric, gynecology, thoracic and general surgery. Systematic reviews, network meta-analyses, and meta-regressions informed operating room (OR) time, hospital stay, and transfusion model inputs. Costs were assigned to model parameters, and price parity was assumed for advanced energy devices. The costs of disposables for dispersive electrodes and smoke-evacuators were included. The base-case analysis, which assessed the adoption of EES instead of MED for an average U.S. hospital predicted an annual savings of $824,760 ($101 per procedure). Savings were attributable to associated reductions with EES in OR time, days of hospital stay, and volume of disposable electrodes. Sensitivity analyses were consistent with these base-case findings. Category-wide adoption of electrosurgical devices from a single manufacturer demonstrated economic advantages compared with disaggregated product uptake. Future research should focus on informing comparisons of innovative electrosurgical devices.

 Halecium tenellum Hincks, 1861b: 252, pl. 6, figs. 1–4.— Jones, 2002: 216.
 Type locality. UK: Devon, Salcombe Bay (Hincks 1961b).
 Voucher material. Jeff’s Reef off Fort Pierce, 27°32.8’N, 79°58.8’W, 80 m, 15.iv.1977, Johnson-Sea-Link, JSL 2184- A, diver lockout, one colony, 1.3 cm high, without gonophores, coll. F. Stanton, ROMIZ B1105.
 Remarks. The morphology of the hydroid examined here approaches accounts of Halecium delicatulum Coughtrey, 1876 (type locality: Upper Harbour, Dunedin, New Zealand) and H. mediterraneum Weismann, 1883 (type locality: Naples, Italy) in having typically long primary hydrophores. However, no pseudodiaphragm such as that often reported in both of those species (e.g., Schuchert 2005) was present in hydrophores of the colony from Florida. It was also small (1.3 cm high) and its hydrocaulus monosiphonic except at the base, as is typical of Halecium tenellum Hincks, 1861b.
 In the western North Atlantic, Fraser (1944) included distribution records of Halecium tenellum from Hudson Strait to the Caribbean Sea. At least some reports of the species from high latitudes have been based on misidentifications (Hamond 1957; Cornelius 1975; Calder 1991a; Schuchert 2005). The species is more likely restricted to temperate and tropical waters. An extensive list of literature pertaining to H. tenellum was given by Medel & Vervoort (2000).
 Reported distribution. Atlantic coast of Florida. Biscayne Bay (Jones 2002).
 Western Atlantic. Possibly from southern New England (Fraser 1944) to Argentina (Oliveira et al. submitted), including Bermuda (Calder 1991a), the Gulf of Mexico (Calder & Cairns 2009), and the Caribbean Sea (Galea 2010).
Elsewhere. Considered a cosmopolitan species by Medel & Vervoort (2000), but see Remarks above.

description: We study both experimentally and theoretically, considering bosonic atoms in a periodic potential, the influence of interactions in a Talbot interferometer. While interactions decrease the contrast of the revivals, we find that over a wide range of interactions the Talbot signal is still proportional to the phase coherence of the matter wave field. Our results confirm that Talbot interferometry can be a useful tool to study finite range phase correlations in an optical lattice even in the presence of interactions. The relative robustness of the Talbot signal is supported by the first demonstration of the three-dimensional Talbot effect.

description: Increasing price volatility of agricultural commodities over the last decade has focused a growing body of literature to identify the influencing factors of price variability. We analyze the effect of increasing wheat export from the Former Soviet Union (FSU) countries to the international wheat market and price volatility. The major wheat producer and exporter FSU countries, Russia, Ukraine and Kazakhstan have experienced increasing share on the international wheat market. An ordinary least square method is applied to estimate the influence of wheat export from Russia, Ukraine and Kazakhstan on the international wheat price volatility. We found evidence of positive relationship between international wheat price and the expanding net wheat export from FSU.
Scaling in a Nonconservative Earthquake Model of Self-Organised Criticality

description: We numerically investigate the Olami-Feder-Christensen model for earthquakes in order to characterise its scaling behaviour. We show that ordinary finite size scaling in the model is violated due to global, system wide events. Nevertheless we find that subsystems of linear dimension small compared to the overall system size obey finite (subsystem) size scaling, with universal critical coefficients, for the earthquake events localised within the subsystem. We provide evidence, moreover, that large earthquakes responsible for breaking finite size scaling are initiated predominantly near the boundary.

The economics of ethical behaviour and environmental management

Subjects: Environmental Economics and Policy

description: Ethics and economics have long been viewed, if not as being incompatible, at least as being at odds with each other. This has often translated in the field of environmental policy and management into radical opposition between supporters of economic performance and environmentalists. It has seemed that the ethics of economics and that of environmental preservation were themselves at odds. The discussion has opposed utilitarian and duty-based philosophies. Ultimately, the firm manager, especially when under financial pressure, must decide between keeping the firm in business and doing the right thing for the environment. This view of things is now itself at odds with reality. One needs to explain why an increasing number of firms, both big and small, are setting up environmental management systems, making environmental investments and reducing risks over and beyond legal requirements, even when the benefits are not at all obvious, even in the long run. Is it that economics and ethics have not only become compatible, but lend support to each other? If so, how is this possible? What are the social processes at work? And can we come up with a theoretical framework that can describe this new reality? Even at the philosophical level, are utility based and duty based ethics as contradictory as they seem? This paper investigates these questions and shows how, philosophically, the two ethics may be efficiently combined and how an analytical framework may be devised to explain society’s new ‘ethical incentives’ and self-moralising processes. A new role for government emerges.

Status of a Supersymmetric Flavour Violating Solution to the Solar Neutrino Puzzle with Three Generations
Creators: name: Dreiner, H. K.
name: Moreau, G.
Publisher: name: arXiv
Year: 2002
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We present a general study of a three neutrino flavour transition model based on the supersymmetric interactions which violate R-parity. These interactions induce flavour violating scattering reactions between solar matter and neutrinos. The model does not contain any vacuum mass or mixing angle for the first generation neutrino. Instead, the effective mixing in the first generation is induced via the new interactions. The model provides a natural interpretation of the atmospheric neutrino anomaly, and is consistent with reactor experiments. We determine all R-parity violating couplings which can contribute to the effective neutrino oscillations, and summarize the present laboratory bounds. Independent of the specific nature of the (supersymmetric) flavour violating model, the experimental data on the solar neutrino rates and the recoil electron energy spectrum are inconsistent with the theoretical predictions. The confidence level of the $χ^2$-analysis ranges between $\sim 10^{-4}$ and $\sim 10^{-3}$. The incompatibility, is due to the new SNO results, and excludes the present model. We conclude that a non-vanishing vacuum mixing angle for the first generation neutrino is necessary in our model. We expect this also to apply to the solutions based on other flavour violating interactions having constraints of the same order of magnitude.

description: Abstract Although, dairying is the most ancient occupation established in the rural setting of Bangladesh, its development is unsatisfactory due to several problems. The main problems concern breeding, feeding, management, diseases and marketing. The dairy sector has also not received adequate attention in respect of information and research with present policies and issues. National milk production can only meet 13% of the current milk consumption. The demand for milk is growing at a faster rate than supply because of the rapid increase in population, creating a widening imbalance between demand and supply. There is a need to have knowledge of the existing demand, its growth over time, and the existing supply possibilities. There are also many types of information needed for proper functioning of markets. In the light of such knowledge it would be necessary to take policy measures for providing strong institutional support to increase domestic production and reduce the imbalance between supply and demand. To address the industry’s problems effectively, sources of market failures and of government policies in contributing to its poor performance are discussed in this paper.
An Empirical Assessment of the ‘International Competitiveness’ of the Australian Processed Food Industry

description: This paper examines the competitiveness of the Australian processed food industry using trade pattern measures and constant market share (CMS) model. The trade orientation criterion adopted in the study revealed that the industry has evolved over the years with an export focus and capable of competing with foreign suppliers in the domestic market. But an important empirical finding is that the industry’s competitive position in foreign markets as a whole has deteriorated over the period between 1980 and 1996 although different sub groups within the industry have shown mixed performance.
Theory of deeply virtual Compton scattering on the nucleon

description: We compute the cross section for leptoproduction of the real photon off the nucleon, which is sensitive to the deeply virtual Compton scattering amplitude with power accuracy. Our considerations go beyond the leading twist and involve the complete analysis in the twist-three approximation. We discuss consequences of the target and lepton beam polarizations for accessing the generalized parton distributions from experimental measurements of the azimuthal angular dependence of the final state photon or nucleon. We introduce several sets of asymmetries, defined as Fourier moments with respect to the azimuthal angle, which allow for a clear separation of the twist-two and -three sectors. Relying on a simple ansatz for the generalized parton distributions, we give quantitative estimates for azimuthal and spin asymmetries, discuss the uncertainties of these predictions brought in by radiative corrections, and compare them with experimental data as well as other theoretical expectations. Furthermore, we derive a general parametrization of the DVCS amplitudes in the region of small Bjorken variable.
