description: Like many countries in sub-Saharan Africa, Zimbabwe is experiencing rapid growth in wheat consumption and imports. Policy makers in Zimbabwe and elsewhere must decide whether increased domestic wheat production might reduce dependency on imports and at the same time contribute to economic efficiency and food security goals. The domestic resource cost framework was used to assess Zimbabwe's comparative advantage among six major irrigated crops and to measure the effects of current government policies on producer incentives. The results indicate that irrigated wheat production represents an efficient use of Zimbabwe's resources during times of abundant rainfall, but the nation enjoys a comparative advantage in tobacco, maize, and cotton production during times of water scarcity. Existing agricultural policies provide disincentives for commercial farmers, because private profitability is less than social profitability for the major irrigated crops. However, this tax occurs across all commodities with similar incidence, so that the private incentives among crops are not greatly distorted from their social pattern. Sensitivity analysis confirms the robustness of these findings under a range of possible future economic and political developments. The domestic resource cost approach used in this study provides an operational method for measuring comparative advantage and should be of interest to policy analysts throughout sub-Saharan Africa.
The Likelihood of Detecting Young Giant Planets with High Contrast Imaging and Interferometry

description: Giant planets are expected to form at orbital radii that are relatively large compared to transit and radial velocity detections (>1 AU). As a result, giant planet formation is best observed through direct imaging. By simulating the formation of giant (0.3-5$M_{J}$) planets by core accretion, we predict planet magnitude in the near infrared (2-4 $μ$m) and demonstrate that, once a planet reaches the runaway accretion phase, it is self-luminous and is bright enough to be detected in near infrared wavelengths. Using planet distribution models consistent with existing radial velocity and imaging constraints, we simulate a large sample of systems with the same stellar and disc properties to determine how many planets can be detected. We find that current large (8-10m) telescopes have, at most a 0.2% chance of detecting a core accretion giant planet in the L' band and 2% in the K band for a typical solar type star. Future instruments such as METIS and VIKiNG have higher sensitivity and are expected to detect exoplanets at a maximum rate of 2% and 8% respectively.

We present three main results: (1) The area distribution of simultaneously failing glue (bursts) follows a power law consistent with the theoretically expected exponent 2.5, (2) the maximum load and displacement before catastrophic failure scale as L^2 and L^0 respectively, where L is the linear size of the system, and (3) the area distribution of failed glue regions (clusters) is a power law with exponent -1.6 when the system fails catstrophically.

description: The relationship between U.S. and world sugar prices, and U.S. import demand for four categories of sugar-containing products is examined. Results from econometric estimation indicate that U.S. intervention in the sugar market has helped to increase U.S. imports of some sugarcontaining products, but that increased disposable income has played a more important role. Although some developing countries have benefitted from U.S. sugar policy by increasing their exports of sugar-containing products to the United States, U.S. sugar policy has helped imports from developed countries proportionately more than those from developing countries as a whole.

description: Interlayer magnetoconductance of the quasi-two dimensional organic metal (BEDT-TTF)8Hg4Cl12(C6H5Cl)2 has been investigated in pulsed magnetic fields extending up to 36 T and in the temperature range from 1.6 to 15 K. A complex oscillatory spectrum, built on linear combinations of three basic frequencies only is observed. These basic frequencies arise from the compensated closed hole and electron orbits and from the two orbits located in between. The field and temperature dependencies of the amplitude of the various oscillation series are studied within the framework of the coupled orbits model of Falicov and Stachowiak. This analysis reveals that these series result from the contribution of either conventional Shubnikov-de Haas effect (SdH) or quantum interference (QI), both of them being induced by magnetic breakthrough. Nevertheless, discrepancies between experimental and calculated parameters indicate that these phenomena alone cannot account for all of the data. Due to its low effective mass, one of the QI oscillation series - which corresponds to the whole first Brillouin zone area - is clearly observed up to 13 K.

description: In this paper we report the results of a pilot study comparing the older and younger adults' interaction with an Android TV application which enables users to detect errors in video subtitles. Overall, the interaction with the TV-mediated crowdsourcing system relying on language profficiency was seen as intuitive, fun and accessible, but also cognitively demanding; more so for younger adults who focused on the task of detecting errors, than for older adults who concentrated more on the meaning and edutainment aspect of the videos. We also discuss participants' motivations and preliminary recommendations for the design of TV-enabled crowdsourcing tasks and subtitle QA systems.
title: Earthquake-Induced Landscape Dynamics (EILD) end-user and stakeholder tools engagement plan

Publisher: name: GNS Science
Year: 2021

description: The 14 November 2016 MW 7.8 Kaikōura Earthquake generated thousands of landslides, hundreds of significant landslide dams and damaged hillslopes that are now susceptible to failure during rainstorms and aftershocks. This debris, when further mobilised, will create new hazards, including further landslides, dams, rapid aggradation and formation of alluvial fans and floodplains, and increased river channel instability as the debris cascades from hillslope to sea. These hazards can persist for decades, requiring active management by the impacted communities and stakeholders. The ‘Earthquake-Induced Landslide Dynamics’ research programme (EILD) is funded from 2018 to 2023 to investigate the impacts of the Kaikōura event and integrate field, laboratory and numerical modelling to determine how the hillslopes and rivers will respond to future forcing events, focusing on: forecasting landslide severity at different magnitudes of ground shaking and rain; quantifying post-earthquake landslide triggering and reactivation thresholds from ground shaking, rain and time; evaluating landslide dam longevity; determining how far landslide debris volumes travel downslope, once triggered; modelling how sediment cascades from hillslope to sea; and assessing the performance of earthworks infrastructure subject to landslide. A set of tools will be developed from the research to inform landslide risk and residual risk-management methods and practices for stakeholders affected by the Kaikōura Earthquake and those that may be affected by future events. Engagement with identified partners, stakeholders and end-users of the EILD research programme will solicit input and encourage collaboration to develop useful, useable and used tools in mitigating against earthquake-induced landslide risks. In addition, the engagement will promulgate the results of the research as widely as possible to relevant end-users. The tools will evolve, along with end-users needs, and therefore the process will be iterative. Initial mapping of output and tools to stakeholders and end-users needs has been undertaken, and an engagement plan over the next three years (2021–2023) has been developed. Many engagement methods will be used, ranging from hui, advisory group meetings, regular programme meetings, specific invited workshops and training, special conference sessions, targeted road shows and surveys. Risks that may hinder or impact engagement and possible mitigations against these risks have been identified. (auth)

description: The United States - one of the world's largest coffee importers - imports coffee beans from a variety of different countries. These countries are aggregated into five groups representing five broadly defined types of coffee. Imports of the five coffees over time are examined to determine price, expenditure and substitution elasticities. These elasticities reflect preferences as well a technical relationships in the form of blending recipes. The lower the degree of substitutability between the different types of coffee, the more inelastic the demand from the United States facing groups of exporting countries. The results suggest rigidities in United States imports of coffee of different types. These rigidities are evidenced by substantial complementarity among the five coffee types. Preference patterns are very similar across a wide range of model specifications. There are differences in expenditure elasticities for different types of coffee in the United States.

We show that, in the absence of external forces, such a system phase-separates into high density and low density regions. We show that this separation is dependent on the inelasticity of collisions, and comment on the mechanism for this clustering behavior. Our results are compatible with the granular clustering seen in experiments and molecular dynamic simulations of inelastic hard disks.

description: A bosonic sector of the four-dimensional low-energy heterotic string theory with two Abelian gauge fields is considered in the stationary case. A new 4X4 unitary null-curvature matrix representation of the theory is derived and the corresponding formulation based on the use of a new 2X2 Ernst type matrix complex potential is developed. The group of hidden symmetries is described and classified in the matrix-valued quasi General Relativity form. A subgroup of charging symmetries is constructed and representation which transforms linearly under the action of this symmetry subgroup is established. Also the solution generation procedure based on the application of the total charging symmetry subgroup to the stationary Einstein-Maxwell theory is analyzed.

description: We present new diagnostic tools for distinguishing supernova remnants (SNRs) from HII regions. Up to now, sources with flux ratio [S II]/H$\rmα$ higher than 0.4 have been considered as SNRs. Here, we present the combinations of three or two line ratios as more effective tools for the separation of these two kinds of nebulae, depicting them as 3D surfaces or 2D lines. The diagnostics are based on photoionization and shock excitation models (MAPPINGS III) analysed with Support Vector Machine (SVM) models for classification. The line-ratio combination that gives the most efficient diagnostic is: [O I]/H$\rmα$ - [O II]/H$\rmβ$ - [O III]/H$\rmβ$. This method gives $98.95\% $ completeness in the SNR selection and $1.20\%$ contamination. We also define the [O I]/H$\rmα$ SNR selection criterion and we measure its efficiency in comparison to other selection criteria.

description: The Hilbert-Chapman-Enskog expansion of the kinetic equations in mean flight times is believed to be asymptotic rather than convergent. It is therefore inadvisable to use lower order results to simplify the current approximation as is done in the traditional Chapman-Enskog procedure, since that is an iterative method. By avoiding such recycling of lower order results, one obtains macroscopic equations that are asymptotically equivalent to the ones found in the Chapman-Enskog approach. The new equations contain higher order terms that are discarded in the Chapman-Enskog method. These make a significant impact on the results for such problems as ultrasound propagation. In this paper, it is shown that these results turn out well with relatively little complication when the expansions are carried to second order in the mean free time, for the example of the relaxation or BGK model of kinetic theory.

description: This paper examines whether developing countries, as a group, would be better off in the absence of agricultural protection in the industrial North and, if so, whether they should support reforms negotiated between the major players in the Uruguay Round. Results from the Tyers-Anderson GLS model of world food markets suggest that the net effect of industrial country agricultural protection is beneficial to developing countries, though by only a small margin, even if its removal were to stimulate accelerated technical change in developing countries. The same is found to be true of partial reforms which are more palatable politically, such as quotas to reduce oversupply in the EC. Of course, many developing countries, including those which are members of the Cairns Group, are badly hurt by protection in the North. Unfortunately, however, they and the other members of that group stand to gain comparatively little from the reduction of oversupply in the EC through quotas.

description: This paper presents a novel control protocol for robust distance-based formation control with prescribed performance in which agents are subjected to unknown external disturbances. Connectivity maintenance and collision avoidance among neighboring agents are also handled by the appropriate design of certain performance bounds that constrain the inter-agent distance errors. As an extension to the proposed scheme, distance-based formation centroid maneuvering is also studied for disturbance-free agents, in which the formation centroid tracks a desired time-varying velocity. The proposed control laws are decentralized, in the sense that each agent employs local relative information regarding its neighbors to calculate its control signal. Therefore, the control scheme is implementable on the agents' local coordinate frames. Using rigid graph theory, input-to-state stability, and Lyapunov based analysis, the results are established for minimally and infinitesimally rigid formations in 2-D or 3-D space. Furthermore, it is argued that the proposed approach increases formation robustness against shape distortions and can prevent formation convergence to incorrect shapes, which is likely to happen in conventional distance-based formation control methods. Finally, extensive simulation studies clarify and verify the proposed approach.

description: Organic conversion subsidies used in Europe are less likely to be politically acceptable in the United States, where organic agriculture development is market-driven. Persistent barriers to conversion in the United States include limited availability of and access to production and market information, training in management systems and cost of conversion-related investments. By determining whether these factors affect the requirement of a subsidy to convert, we can suggest whether U.S. policy makers need to provide subsidies to encourage conversion and identify policy variables consistent with market-based approaches that could stimulate conversion. A utility difference model is used with Swedish data to analyze factors that determine whether a subsidy is required to motivate organic conversion. The results show that farmers requiring subsidies manage larger less-diversified farms and are more concerned with organic inspection, quality, and adequacy of technical advice. Access to more market outlets and information sources substitutes for payment level in the farmer's utility function, indicating that services rather than subsidies may be used to encourage organic agriculture. To the extent that conditions are similar in the U.S. organic sector, market-based programs such as cost-sharing for conversion and market access improvement should stimulate growth of this industry. © 2000 Elsevier Science B.V.

description: One of the earliest quantum algorithms was discovered by Bernstein and Vazirani, for a problem called Recursive Fourier Sampling. This paper shows that the Bernstein-Vazirani algorithm is not far from optimal. The moral is that the need to "uncompute" garbage can impose a fundamental limit on efficient quantum computation. The proof introduces a new parameter of Boolean functions called the "nonparity coefficient," which might be of independent interest.

description: Understanding the ultrafast coupling and relaxation mechanisms between valleys in transition metal dichalcogenide semiconductors is of crucial interest for future valleytronic devices. Recent ultrafast pump-probe experiments showed an unintuitive significant bleaching at the excitonic $B$ transition after optical excitation of the energetically lower excitonic $A$ transition. Here, we present a possible microscopic explanation for this surprising effect. It is based on the joint action of exchange coupling and phonon-mediated thermalization into dark exciton states and does not involve a population of the B exciton. Our work demonstrates how intra- and intervalley coupling on a femtosecond timescale governs the optical valley response of 2D semiconductors.

REAL TIME COMPUTING
MATRIX FREE
ITERATIVE SOLVER

description: The Multiconjugate adaptive Optics Relay For ELT Observations (MORFEO) is one of the key Adaptive Optics (AO) systems on the ELT, aiming for a good wavefront correction over a large field of view. To compensate for the rapidly changing atmospheric distortions, a control algorithm computes in real-time the optimal shapes of the deformable mirrors from the wavefront sensor data. The control problem can be formulated in a matrix-based or a matrix-free way. In this paper we give an overview on existing AO real-time control algorithms and study the differences between matrix-based and matrix-free implementations via numerical simulations in COMPASS. For the numerical experiments we focus on the Finite Element Wavelet Hybrid Algorithm (FEWHA). Originally, this algorithm is formulated in a matrix-free and iterative way, however, FEWHA can be represented as a matrix-vector multiplication as well. We address whether the iterative approach affects the reconstruction quality in comparison to a direct one. Moreover, we study the computational performance of the matrix-free algorithm on a CPU vs. the matrix-based version on a GPU.

description: In this paper, the demand for beer, wine, spirits and soft drinks in Ontario is modeled in two parts: an equation is specified to endogenize group expenditures and a demand system is set up to allocate budgeted group expenditures across ,types of beverages. Advertising is allowed to influence both the level of group expenditures and its allocation. Three popular advertising specifications are compared using the ]-test and the likelihood dominance criterion. Even though all three specifications fitted well according to standard criteria, the calculated expenditure, price and advertising elasticities were sensitive to the manner with which advertising is specified. This clearly highlights the need to rely on a sound criterion to identify a dominant specification. From the identified dominant specification, we found that advertising has very subtle effects on expenditures on alcoholic beverages (group and individual beverages). Thus, advertising is not effective in enlarging markets and this suggests that firms (especially breweries) use advertising to compete in zero-sum market share games. From a public policy perspective, our results are comforting but future research should investigate whether the neutral effect of advertising on aggregated expenditures hide substantial offsetting changes in the drinking habits of individuals. © 2000 Elsevier Science B.V.

description: We assess the potentiality of several geometries of metallic nanodimers (one of the simplest thermoplasmonic systems) as candidates for active particles (nanoswimmers) propelled and controlled by light (phototaxis). The studied nanodimers are formed by two spherical nanoparticles of gold, silver, or copper with radii ranging from 20 to 100 nm. Contrary to most proposals, which assume the asymmetry of the systems as a requirement for self-propulsion, our results show that nanodimers made of identical nanoparticles are excellent candidates for phototactic self-thermophoretic systems. Nonsymmetrical nanodimers, although having a tunable effective diffusion, possess much lower or zero average thermophoretic forces. We show that the effective diffusion and the net thermophoretic force in both types of systems depend strongly on the wavelength of the incident light, which makes these properties highly tunable. Our study may be useful for the design of simple-to-make but controllable self-propelled nanoparticles. This can find numerous applications ranging from autonomous drug-carrying to controlling the self-assembly of complex nanomaterials.

Using our commutation technique for interacting close-to-boson particles, we here calculate the hamiltonian expectation value in the $N$-ground-state-exciton state.Coulomb interaction enters this quantity at first order only by construction ; nevertheless, due to Pauli exclusion, subtle many-body effects take place, which give rise to terms in $(Na_x^3/\mathcal{V})^n$ with $n\geq2$ >. An \emph{exact} procedure to get these density dependent terms is given.

description: As part of the mm-Wave Interferometric Survey of Dark Object Masses (WISDOM), we present a measurement of the mass of the supermassive black hole (SMBH) in the nearby early-type galaxy NGC 0383 (radio source 3C 031). This measurement is based on Atacama Large Millimeter/sub-milimeter Array (ALMA) cycle 4 and 5 observations of the 12CO(2-1) emission line with a spatial resolution of 58x32pc2 (0."18x0."1). This resolution, combined with a channel width of 10 km/s, allows us to well resolve the radius of the black hole sphere of influence (measured as R_SOI = 316pc = 0."98), where we detect a clear Keplerian increase of the rotation velocities. NGC 0383 has a kinematically-relaxed, smooth nuclear molecular gas disc with weak ring/spiral features. We forward-model the ALMA data cube with the Kinematic Molecular Simulation (KinMS) tool and a Bayesian Markov Chain Monte Carlo method to measure a SMBH mass of (4.2+/-0.7)x10^9 Msun, a F160W-band stellar mass-to-light ratio that varies from 2.8+/-0.6 Msun/Lsun in the centre to 2.4+/-0.3 Msun/Lsun at the outer edge of the disc and a molecular gas velocity dispersion of 8.3+/-2.1 km/s (all 3-sigma uncertainties). We also detect unresolved continuum emission across the full bandwidth, consistent with synchrotron emission from an active galactic nucleus. This work demonstrates that low-J CO emission can resolve gas very close to the SMBH (~140,000 Schwarzschild radii) and hence that the molecular gas method is highly complimentary to megamaser observations as it can probe the same emitting material.

description: A double hurdle model of off-farm work participation and off-farm labour income was derived and estimated consistent with a farm household model. It was found that rationing and unexpected transaction costs inhibit farm households from participating in off-farm work. The 1992 and the Agenda 2000 CAP reforms are most likely to increase the off-farm employment of arable farm households, but its full effect cannot be realised because of inhibitions to enter off-farm activities. Household and farm characteristics have different impacts on off-farm work participation and on the level of off-farm labour income. © 2000 Elsevier Science B.V. All rights reserved.
Holstein polarons in a strong electric field: delocalized and stretched states

description: The coherent dynamics of a Holstein polaron in strong electric fields is considered under different regimes. Using analytical and numerical analysis, we show that even for small hopping constant and weak electron-phonon interaction, the original discrete Wannier-Stark (WS) ladder electronic states are each replaced by a semi-continuous band if a resonance condition is satisfied between the phonon frequency and the ladder spacing. In this regime, the original localized WS states can become {\em delocalized}, yielding both `tunneling' and `stretched' polarons. The transport properties of such a system would exhibit a modulation of the phonon replicas in typical tunneling experiments. The modulation will reflect the complex spectra with nearly-fractal structure of the semi-continuous band. In the off-resonance regime, the WS ladder is strongly deformed, although the states are still localized to a degree which depends on the detuning: Both the spacing between the levels in the deformed ladder and the localization length of the resulting eigenfunctions can be adjusted by the applied electric field. We also discuss the regime beyond small hopping constant and weak coupling, and find an interesting mapping to that limit via the Lang-Firsov transformation, which allows one to extend the region of validity of the analysis.

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

description: The decision of how much time to allocate to meal preparation is an endogenous variable to be determined by the opportunity cost of time, preference between market and nonmarket goods and leisure, and household production technology. Using consumer survey data collected in Bulgaria in 1997, this study measured the effect of household income on the amount of time allocated to meal preparation after controlling the effects of demographic, socio-economic and other characteristics of households. We used the first-hurdle dominance model to distinguish non-meal preparers from meal preparers. Since the overall pattern of allocating time between market work, household activity and leisure in a particular country is likely to be conditional on the stage of its economic development, this study presents a unique opportunity to assess the rationality of the time allocation behavior of consumers in an economy in transition from a centrally-planned to a market-oriented system. Results showed that household income did not influence the decision of how much time to allocate to meal preparation. While the insignificant linkage between income and time allocation to meal preparation could be due to the differences in preference and household production technology. It can be also attributed to the legacy of four decades of a central-planning system and underdeveloped food manufacturing and service industries. © 2000 Elsevier Science B.V. All rights reserved.
Generation of the bosonic string theory solutions from the stationary Einstein fields via projection symmetry

Year: 2001
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: A new formalism for generation of solutions in the consistently truncated low-energy bosonic string theory is developed. This formalism gives a correspondence of the projection type between the theories toroidally compactified from the diverse to three dimensions. Taking the stationary Einstein-dilaton gravity as the theory with a lower dimension, we generate its bosonic string theory extension and calculate the bosonic string theory solution corresponding to the Kerr-NUT one modified by the presence of the charged dilaton field.

description: This paper assesses the recent changes in rural employment in the OECD countries, highlighting the growing role of employment in services and, in some cases, manufacturing activity. In many, but not all, rural areas the secular decline in agricultural employment has been more than counterbalanced by growing employment in these other sectors. However, the diversity of employment growth within and between rural areas is stressed, as are the implications of this diversity for policy. A range of explanations for the relative economic success of some rural areas is explored. These include the impacts of globalisation; restructuring of the labour market; new 'consumption' demands on the rural areas; and human mobility. The paper concludes that traditional theories do not explain the diversity of outcomes in rural areas. New approaches are needed. Recent analyses under the banner of 'the new economic geography' has advanced our understanding of the pre-conditions for rural development to occur, but understanding the diverse pattern of rural employment outcomes within the same kind of geography remains a challenge which needs to be addressed by inter-disciplinary approaches and methods. © 2000 Elsevier Science B.V.

description: Die Liturgiewissenschaft versteht sich als „Grenzgängerin“ (B. Kranemann) in der
Theologie, hat aber auch selbst Grenzbereiche, die in den Curricula kaum oder
gar nicht Berücksichtigung finden, obwohl diese in der Pastoral präsenter werden.
Vorliegender Beitrag möchte anhand eines an der Universität Wien durchgeführten
Seminars zu den drei exemplarischen Feldern Gehörlosigkeit, Tod und
Demenz ein Lehrprojekt reflektieren, dessen Grundidee wesentlich auf der Verbindung
von Fachdidaktik und Religionsdidaktik beruhte und so eine produktive
und erfahrungsintensive Lernmodellierung ermöglichte.
