description: Well-managed, agriculturally used peatlands play an important role for the storage of greenhouse gases. A new agri-environmental measure (AEM) was established in the European Common Agricultural Policy to incentivise a land management, which conserves climate functionality of peatlands through high water levels. To investigate which factors influence the willingness of farmers to participate in this measure, we carried out an empirical study applying a discrete choice experiment (DCE). The aim was to identify optimal contract designs that can also reduce transaction costs for farmers. Besides monetary compensation, measure characteristics such as contract length, assured purchase of the cut grass, support in the cooperation with neighbouring farmers, and administrative efforts are considered as decisive attributes. Results show that the average willingness to adopt the measure is set at 522 /ha*a. Moreover, we find that factors such as supporting cooperation among farmers and regional value chain approaches have a statistically significant and large positive influence on the adoption decision. Based on our results, the uptake and success of the new measure could therefore be increased by a more appropriate tailoring towards different farm types and their needs. Adjustments would increase the climate protection potential of the proposed measure.

description: Personal IoT data is a new economic asset that individuals can trade to generate revenue on the emerging data marketplaces. Typically, marketplaces are centralized systems that raise concerns of privacy, single point of failure, little transparency and involve trusted intermediaries to be fair. Furthermore, the battery-operated IoT devices limit the amount of IoT data to be traded in real-time that affects buyer/seller satisfaction and hence, impacting the sustainability and usability of such a marketplace. This work proposes to utilize blockchain technology to realize a trusted and transparent decentralized marketplace for contract compliance for trading IoT data streams generated by battery-operated IoT devices in real-time. The contribution of this paper is two-fold: (1) we propose an autonomous blockchain-based marketplace equipped with essential functionalities such as agreement framework, pricing model and rating mechanism to create an effective marketplace framework without involving a mediator, (2) we propose a mechanism for selection and allocation of buyers' demands on seller's devices under quality and battery constraints. We present a proof-of-concept implementation in Ethereum to demonstrate the feasibility of the framework. We investigated the impact of buyer's demand on the battery drainage of the IoT devices under different scenarios through extensive simulations. Our results show that this approach is viable and benefits the seller and buyer for creating a sustainable marketplace model for trading IoT data in real-time from battery-powered IoT devices.

description: We report for the first time Na and O abundances from high-resolution, high S/N echelle spectra of 20 red giants in NGC 2808, taken as part of the Science Verification program of the FLAMES multi-object spectrograph at the ESO VLT. In these stars, spanning about 3 mag from the red giant branch (RGB) tip, large variations are detected in the abundances of oxygen and sodium, anticorrelated with each other; this is a well known evidence of proton-capture reactions at high temperatures in the ON and NeNa cycles. One star appears super O-poor; if the extension of the Na-O anticorrelation is confirmed, NGC 2808 might reach O depletion levels as large as those of M 13. This result confirms our previous findings based on lower resolution spectra (Carretta et al. 2003) of a large star-to-star scatter in proton capture elements at all positions along the RGB in NGC 2808, with no significant evolutionary contribution. Finally, the average metallicity for NGC 2808 is [Fe/H]= -1.14 +/- 0.01 dex (rms=0.06) from 19 stars.

description: With the widespread growth of mobile phone coverage and adoption over the past decade, there has been considerable enthusiasm over the use the ICTs in agricultural initiatives, primarily to disseminate information to farmers. This paper assesses farmers willingness to pay (WTP) for a newly introduced digital nutrition-sensitive agricultural information service in Ghana, called Vodafone Farmers Club (VFC). Using both an experimental game and administrative data, we find that the share of farmers willing-to-pay for VFC service is high at low prices and then decreases rapidly as the price increases; at 1.0 GHC, 85% would register for the service; at 2.0 GHC 50% would register; and at 3.0 GHC, just 19% would still be willing to participate. We experimentally vary both the framing around the introduction of VFC to emphasize either the platform s nutrition and agriculture information or the agriculture information alone and the gender of the household member invited to play the game and find that women have statistically lower WTP than men, but the framing has no impact on WTP.

description: The "Spot Check List" (SCL) approach is an important tool developed to help detect and deter fraud, waste, and abuse in the U.S. crop insurance program. This article carefully examines whether the SCL approach affects producers' claims filing behavior and provides insights with regards to the effectiveness of this program. Using proprietary county-level SCL data and panel data econometric procedures (which controls for both observable and unobservable confounding factors), we find evidence that counties with more than three producers included in the SCL tend to have better actuarial performance (i.e., less claims) after being informed about listing in the SCL. This indicates that the SCL procedure seem to be a promising tool for fraud mitigation in the Federal crop insurance program. Acknowledgement :

description: Child labor is a social problem with economic consequences for the growth and development of countries in the short and long term, affecting children's physical and mental development because it interferes with their future wages. In paper we seek to investigate how negative income shocks and economic assets are associated with child labor and school attendance in the Dominican Republic. This issue is particularly important in rural areas, where people are more prone to suffer exogenous shocks and have fewer tools to mitigate them. We used microdata from the Encuesta Nacional de Hogares de Prop sitos Multiples (ENHOGAR) for 2010. Our The empirical strategy was based on a bivariate probit for considering that the decision to allocate children's time to work and/or study are interdependent. The results show that assets positively affect the decision to allocate children towards schooling. On the other hand, negative household income shocks increase the probability of child labor. We also find evidence that in Dominican Republic, children's time does not seem to compete with his or her time in school and the presence of assets is not able to reduce the negative effects of the shocks.

description: We present the analysis of a very high-magnification ($A\sim 900$) microlensing event KMT-2019-BLG-1953. A single-lens single-source (1L1S) model appears to approximately delineate the observed light curve, but the residuals from the model exhibit small but obvious deviations in the peak region. A binary lens (2L1S) model with a mass ratio $q\sim 2\times 10^{-3}$ improves the fits by $Δχ^2=181.8$, indicating that the lens possesses a planetary companion. From additional modeling by introducing an extra planetary lens component (3L1S model) and an extra source companion (2L2S model), it is found that the residuals from the 2L1S model further diminish, but claiming these interpretations is difficult due to the weak signals with $Δχ^2=16.0$ and $13.5$ for the 3L1S and 2L2L models, respectively. From a Bayesian analysis, we estimate that the host of the planets has a mass of $M_{\rm host}=0.31^{+0.37}_{-0.17}~M_\odot$ and that the planetary system is located at a distance of $D_{\rm L}=7.04^{+1.10}_{-1.33}~{\rm kpc}$ toward the Galactic center. The mass of the securely detected planet is $M_{\rm p}=0.64^{+0.76}_{-0.35}~M_{\rm J}$. The signal of the potential second planet could have been confirmed if the peak of the light curve had been more densely observed by followup observations, and thus the event illustrates the need for intensive followup observations for very high-magnification events even in the current generation of high-cadence surveys.

description: The export tax rebate policy in Chinese fishery sector is under dispute, as it is claimed that it works as a subsidy for foreign consumers rather than domestic producers. This paper investigates the distribution of benefits of this policy in the fishery sector. We find that the effects of the export tax rebate on domestic producers depend on the relative magnitude of the export supply and import demand elasticities. After applying the best-bet parameter values, simulation results indicate that, although the export tax rebate does improve Chinese producers welfare, foreign consumers capture most of the welfare benefits of this policy (60%-75%). Furthermore, the results imply that the welfare gain for Chinese producers is overestimated if the vertical linkage between the retail and the farm markets is ignored.

We show that the asymmetric shot noise as function of frequency shows steps and becomes super-Poissonian. This provides experimental access to the quantum fluctuations of the current. We present an exact calculation for a single dot level and a perturbative evaluation of the noise in Born approximation (sequential tunneling regime but without Markov approximation) for the general case of many levels with charging interaction.

Both are expected to provide new supergravity duals of superconformal field theories.

description: We put forward the idea that classical blockchains and smart contracts are potentially useful primitives not only for classical cryptography, but for quantum cryptography as well. Abstractly, a smart contract is a functionality that allows parties to deposit funds, and release them upon fulfillment of algorithmically checkable conditions, and can thus be employed as a formal tool to enforce monetary incentives. In this work, we give the first example of the use of smart contracts in a quantum setting. We describe a simple hybrid classical-quantum payment system whose main ingredients are a classical blockchain capable of handling stateful smart contracts, and quantum lightning, a strengthening of public-key quantum money introduced by Zhandry (Eurocrypt'19). Our hybrid payment system employs quantum states as banknotes and a classical blockchain to settle disputes and to keep track of the valid serial numbers. It has several desirable properties: it is decentralized, requiring no trust in any single entity; payments are as quick as quantum communication, regardless of the total number of users; when a quantum banknote is damaged or lost, the rightful owner can recover the lost value.

description: Objective: Bronchial hyperresponsiveness (BHR) is a representative feature of asthma. Although methacholine and mannitol are commonly used for bronchial challenge tests, the optimal roles of the two agents for assessing BHR remain unclear. We compared the diagnostic performance of methacholine and mannitol in bronchial challenge tests. Methods: A systematic literature search was performed using MEDLINE, EMBASE, and the Cochrane Central Register. The sensitivity, specificity, diagnostic odds ratio (DOR), and a hierarchical summary of the receiver-operating characteristic curve (HSROC) of the two agents for detecting BHR in asthma were pooled using meta-analysis. A meta-regression analysis was used to identify potential sources of heterogeneity within the selected studies. Results: We identified six studies comprising 565 patients. The pooled sensitivity, specificity, and DOR of methacholine were 0.61 (95%CI, 0.44-0.76), 0.93 (95%CI, 0.70–0.99), and 23.47 (95% CI, 2.51–219.89), respectively. The pooled sensitivity, specificity, and diagnostic odds ratio of mannitol were 0.50 (95%CI, 0.28–0.73), 0.97 (95% CI, 0.94–0.99), and 35.22 (95% CI, 8.82–140.62), respectively. The area under the HSROC for mannitol was higher than that for methacholine (0.97 vs. 0.81, p Conclusion: Although mannitol showed better diagnostic performance than methacholine for identifying BHR in asthma, substantial between-study heterogeneity necessitates caution when interpreting the data.

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Deep JHKs photometry was obtained towards eight dense molecular cores and J-H vs. H-Ks color-color plots are presented. Our photometry, sensitive to the detection of a 1 solar mass, 1 X 10^6 year old star through approx. 35 - 50 magnitudes of visual extinction, shows no indication of the presence of star/disk systems based on J-H vs. H-Ks colors of detected objects. The stars detected towards the cores are generally spatially anti-correlated with core centers suggesting a background origin, although we cannot preclude the possibility that some stars detected at H and Ks alone, or Ks alone, are not low mass stars or brown dwarfs (< 0.3 Solar Masses) behind substantial amounts of visual extinction (e.g. 53 magnitudes for L183B). Lower limits to optical extinctions are estimated for the detected background stars, with high extinctions being encountered, in the extreme case ranging up to at least Av = 46, and probably higher. The extinction data are used to estimate cloud masses and densities which are comparable to those determined from molecular line studies. Variations in cloud extinctions are consistent with a systematic nature to cloud density distributions and column density variations and extinctions are found to be consistent with submillimeter wave continuum studies of similar regions. The results suggest that some cores have achieved significant column density contrasts (approx. 30) on sub-core scales (approx. 0.05 pc) without having formed known stars.

description: As known from Einstein's theory of general relativity, the propagation of light in the presence of a massive object is affected by gravity. In this work, we discuss whether the effect of gravitational light bending can be observed in Earth-based experiments, using high-finesse optical cavities. In order to do this, we theoretically investigate the dynamics of electromagnetic waves in the spacetime of a homogeneous gravitational field and give an analytical expression for the resulting modifications to Gaussian beam propagation. This theoretical framework is used to calculate the intensity profile at the output of a Fabry-Pérot cavity and to estimate the imprints of Earth's gravity on the cavity output signal. In particular, we found that gravity causes an asymmetry of the output intensity profile. Based on that, we discuss a measurement scheme, that could be realized in facilities like the GEO600 gravitational wave detector and the AEI 10 m detector prototype.

description: It is widely accepted that China's agrarian economy is experiencing a profound capitalization/modernization transformation. Peasants in Houjiaying village, where I conducted my field research,however, have been excluded from this great transition and instead are experiencing unstable development. At the same time, peasants in Jingerzhuang village, only two kilometers away, are getting rich by planting vegetables and have successfully achieved the transition from "old farming" to "new agriculture." Why are people who live only two kilometers apart experiencing totally different development paths? This article intended to answer the above question and explore the formation and development process of China's "new agriculture"(both labor and capital intensive) based on the micro experiences of four villages since 1936 until 2015 in eastern Hebei Province (North China). In addition to the Manchuria Railway Materials of North China (1936-1941), local archives (including soil and water records) and statistics since 1949 are used. By using grounded theory analysis and process tracking methods, and the GIS software, we draw the conclusion that the changing natural environmental constraints (soil types and irrigation condition) and village governance structure were playing an important role during this great transition.

description: We investigate the wealth evolution in a system of agents that exchange wealth through a disordered network in presence of an additive stochastic Gaussian noise. We show that the resulting wealth distribution is shaped by the degree distribution of the underlying network and in particular we verify that scale free networks generate distributions with power-law tails in the high-income region. Numerical simulations of wealth exchanges performed on two different kind of networks show the inner relation between the wealth distribution and the network properties and confirm the agreement with a self-consistent solution. We show that empirical data for the income distribution in Australia are qualitatively well described by our theoretical predictions.

Year: 2020
Subjects: subject: Dynamical Systems (math.DS)

description: We introduce a generalized numerical algorithm to construct the solution landscape, which is a pathway map consisting of all stationary points and their connections. Based on the high-index optimization-based shrinking dimer (HiOSD) method for gradient systems, a generalized high-index saddle dynamics (GHiSD) is proposed to compute any-index saddles of dynamical systems. Linear stability of the index-$k$ saddle point can be proved for the GHiSD system. A combination of the downward search algorithm and the upward search algorithm is applied to systematically construct the solution landscape, which not only provides a powerful and efficient way to compute multiple solutions without tuning initial guesses, but also reveals the relationships between different solutions. Numerical examples, including a three-dimensional example and the phase field model, demonstrate the novel concept of the solution landscape by showing the connected pathway maps.

description: Determinant factors of high performing agricultural regions. One indicator of agricultural performance is the agricultural labour productivity, as measured by the gross value added per annual working unit. Econometric approaches have been used to evaluate factors contributing to such productivity. However, these estimates require detailed data that often are not available at the regional level. We propose an alternative approach to disentangle the contribution of different drivers that lead to high productivity in EU regions, defined at NUTS 2 level. The fuzzy set Qualitative Comparative Analysis (fsQCA) provides a framework to identify combinations of attributes present in the most productive EU regions, by revealing pathways or sets of sufficient drivers present in such cases. We selected drivers based on previous research, and our findings show that there is not a unique pathway to reach high agricultural productivity. However, some drivers as strong farm structure and relevant public support appear in most of the pathways. Other dimensions related to research, development and innovation, and to natural conditions, seem also relevant.

description: Despite economic transformations and urbanization, declining shares of the workforce employed in the agricultural sector, production costs in the agricultural sector and food prices remain high in Nigeria relative to those in some of the other developing countries. Understanding how the adoption of mechanical technologies is related to agricultural productivity is therefore important for countries like Nigeria. Using farm household data from northern Nigeria as well as various spatial agroclimatic data, this study shows that the adoption of key mechanical technologies in Nigerian agriculture (animal traction, tractors, or both) has been high in areas that are more agroclimatically similar to the locations of agricultural research and development (R&D) stations, and this effect is heterogeneous, being particularly strong among relatively larger farms. Furthermore, such effects are likely to have been driven by the rise in returns on scale in the underlying production function caused by the adoption of these mechanical technologies. Agricultural mechanization, represented here as the switch from manual labor to animal traction and tractors, has been not only raising the average return on scale but also potentially magnifying the effects of productivity-enhancing public-sector R&D on spatial variations in agricultural productivity in countries like Nigeria.

description: ABRIDGED: To compare the chemistries of stars in the Milky Way dSph galaxies with stars in the Galaxy, we have compiled a large sample of Galactic stellar abundances from the literature. As found in previous studies, the [alpha/Fe] ratios of most stars in the dSph galaxies are generally lower than similar metallicity Galactic stars in this extended sample. Our kinematically selected stars confirm that this is true for all major stellar components of the Galaxy, including the halo, thin disk, and thick disk. There is marginal overlap in the low [alpha/Fe] ratios between dSph stars and Galactic halo stars on extreme retrograde orbits, but this is not supported by other element ratios, like [Ba/Y]. Thus, the full chemical signature of most of the dSph stars are distinct from the main components of the Galaxy. This result rules out continuous merging of low mass galaxies similar to these dSph satellites during the formation of the Galaxy, which is discuss further. The new environments offered by the dSph galaxies also allow us to examine fundamental assumptions related to nucleosynthesis. The metal-poor stars ([Fe/H] < -1.8) in the dSph galaxies have [alpha/Fe] ratio that are consistent with predictions from the alpha-process (alpha-rich freeze out). This may also explain the very low Y abundances, and could suggest a separate r-process site for this light (first peak r-process) element. In stars with higher metallicities ([Fe/H] > -1.8), contributions from the s-process are expected; [Ba/Y] is still much higher in the dSph stars than similar metallicity Galactic stars though, consistent with s-process contributions from only the low metallicity AGB stars in dSph galaxies. Finally, the Na-Ni trend in Galactic halo stars is confirmed, but discuss this in terms of nucleosynthesis, and not the accretion of dSphs.

Isospin fractionation in the nucleon emissions and fragment emissions in the intermediate energy heavy ion collisions

description: The degree of isospin fractionation is measured by $(N/Z)_{n}$ / $(N/Z)_{N_{imf}}$, where $(N/Z)_{n}$ and $(N/Z)_{N_{imf}}$ are the saturated neutron-proton ratio of nucleon emissions (gas phase) and that of fragment emissions (liquid phase) in heavy ion collision at intermediate energy . The calculated results by using the isospin-dependent quantum molecular dynamics model show that the degree of isospin fractionation is sensitive to the neutron-proton ratio of colliding system but insensitive to the difference between the neutron-proton ratio of target and that of projectile. In particular, the degree of isospin fractionation sensitively depends on the symmetry potential. However its dependences on the isospin dependent in-medium nucleon-nucleon cross section and momentum dependent interaction are rather weak. The nucleon emission (gas phase) mainly determines the dynamical behavior of the degree of isospin fractionation in the isospin fractionation process, compared to the effect of fragment emission. In this case, we propose that $(N/Z)_{n}$ / $(N/Z)_{N_{imf}}$ or $(N/Z)_{n}$ can be directly compared with the experimental data so that the information about symmetry potential can be obtained

description: Climate change is predicted to increase the number and severity of extreme rainfall events, especially in Sub-Saharan Africa. In response, development agencies are encouraging the adoption of `climate-smart' agricultural techniques, such as conservation agriculture (CA). However, little rigorous evidence exists to demonstrates the effect of CA on production or climate resilience, and what evidence there is, is hampered by selection bias. Using panel data from Zimbabwe, we test how CA performs during extreme rainfall events - both shortfalls and surpluses. We control for the endogenous adoption decision and find that while CA has little, or if anything, a negative effect on yields during periods of average rainfall, it is effective in mitigating the negative impacts of rainfall shocks. Households that practice CA tend to receive higher yields compared to households using conventional methods in years of both low and high rainfall. We conclude that the lower yields during normal rainfall seasons may be a proximate factor in low uptake of CA. Policy should focus promotion of CA on these climate resiliency benefits.

description: In this report. A 1989 U.S. Department of Agriculture (USDA) survey of cotton producers reveals that 82 percent of cotton acreage was fertilized with nitrogen, 93 percent was treated with herbicides, and 67 percent was treated with insecticides. The survey also found cotton producers were using nonchemical pest management practices, including cultivation on 97 percent of planted acreage and pest scouting programs on 56 percent of planted acreage. Soil conservation was not as widely adopted, partly due to climate and topography in cotton-growing regions. About 60 percent of the surveyed acreage contained a well on the operation, but not many respondents knew if the well contained pesticides or nitrates

description: This paper reviews broad literature on political economy as related to agricultural trade. A framework for the analysis of policy in markets subject to extensive government interventions is developed. Literature is reviewed that addresses domestic policy formation in the political arena and the linkages between domestic political choices and their ramifications in international markets. The literature is characterized by a wide variety of models and quantitative techniques. There appears to be no convergence to a general model for endogenizing government behavior as results are often conflicting. One recurring theme is that the problem should dictate the model.

description: The worldwide advanced gravitational-wave (GW) detector network has so far primarily consisted of the two Advanced LIGO observatories at Hanford and Livingston, with Advanced Virgo joining the 2016-7 O2 observation run at a relatively late stage. However Virgo has been observing alongside the LIGO detectors since the start of the O3 run; in the near future, the KAGRA detector will join the global network and a further LIGO detector in India is under construction. Gravitational-wave search methods would therefore benefit from the ability to analyse data from an arbitrary network of detectors. In this paper, we extend the PyCBC offline compact binary coalescence (CBC) search analysis to three or more detectors, and describe resulting updates to the coincident search and event ranking statistic. For a three-detector network, our improved multi-detector search finds 23% more simulated signals at fixed false alarm rate in idealized colored Gaussian noise, and up to 40% more in real data, compared to the two-detector analysis previously used during O2.

description: State per capita incomes diverged beginning in 1979, reversing a 50-year trend.. By 1989, State per capita income inequality, as measured by the coefficient of variation, had increased 41 percent from its 1979 value to its highest level in over 20 years. States in which real per capita income was greater than the national mean in 1979 and grew faster than the national mean accounted for most of the increase. Atlantic Coast States accounted for a large portion of the increase, as did States in which producer services accounted for a large share of total earnings. States dependent on hightechnology manufacturing, energy, farm, and traditional manufacturing accounted for less of the increase. Projections of future levels of inequality, based on alternative assumptions about per capita income growth, yield mixed results, ranging from a 10-percent decrease to a 56-percent increase in the coefficient of variation from 1989 to 1995.
