description: A decomposition analysis of horticultural trade flows is carried out to identify the main sources of change in EC horticultural imports from different LDC regions. Sources of change are associated with each region's international competitiveness, the relative openness of the EC market, the degree of trade preference enjoyed by the region, and the EC global import growth. The main contribution to the LDC export growth of fruit and vegetables to EC between 1975-79 and 1985-89 is found to be attributable to the global import growth effect. However, it has been significantly counteracted by the negative effect of a declining share of non-EC suppliers as a group. Marked interregional differences in changes in regional preferences show a lack of a strong correlation between LDC export performance and the existence of preferential trade agreements with EC. While the potential for LDC export growth to EC is clear, the results seem to indicate that in general EC protection policies have adversely affected import growth from LDCs. Various factors influencing LDC export performance in horticultural products arc discussed. Apart from EC protection policies and changes in trade preferences, domestic supply factors arc of significance in explaining export growth, including a liberal trading environment, but also specific policies to promote exports of horticultural products. While non-price competition weakens the discriminatory effect of preferential tariffs, there is a pressing need for developing countries to adapt to the demands of the European distribution system relating to quality, grades, and regularity of supplies.

description: We show that in the SU(2) Georgi-Glashow model, 't Hooft-Polyakov monopoles are produced by a classical instability in magnetic fields above the Ambjorn-Olesen critical field, which coincides approximately with the field at which Schwinger pair production becomes unsuppressed. Below it, monopoles can be produced thermally, and we show that the rate is higher than for pointlike monopoles by calculating the sphaleron energy as a function of the magnetic field. The results can be applied to production of monopoles in heavy-ion collisions or in the early Universe.

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: Quantitative predictions are presented of a depletion-induced torque and force acting on a single colloidal hard rod immersed in a solvent of hard spheres close to a planar hard wall. This torque and force, which are entirely of entropic origin, may play an important role for the key-lock principle, where a biological macromolecule (the key) is only functional in a particular orientation with respect to a cavity (the lock).

description: Approximating kernel functions with random features (RFs)has been a successful application of random projections for nonparametric estimation. However, performing random projections presents computational challenges for large-scale problems. Recently, a new optical hardware called Optical Processing Unit (OPU) has been developed for fast and energy-efficient computation of large-scale RFs in the analog domain. More specifically, the OPU performs the multiplication of input vectors by a large random matrix with complex-valued i.i.d. Gaussian entries, followed by the application of an element-wise squared absolute value operation - this last nonlinearity being intrinsic to the sensing process. In this paper, we show that this operation results in a dot-product kernel that has connections to the polynomial kernel, and we extend this computation to arbitrary powers of the feature map. Experiments demonstrate that the OPU kernel and its RF approximation achieve competitive performance in applications using kernel ridge regression and transfer learning for image classification. Crucially, thanks to the use of the OPU, these results are obtained with time and energy savings.

description: This paper uses a flexible (translog) production function to estimate efficiency of 227 farms from West Bengal, India. We consider estimation of technical and allocative inefficiencies using a profit maximising framework which accommodates both endogenous and exogenous inputs. The maximum likelihood method of estimation developed in this paper is based on the production function and the first-order conditions of profit maximisation. Farm-specific technical and allocative inefficiencies are also estimated. Empirical results show that the mean level of technical efficiency is 75.46% while the best farm is 85.87% efficient (technically). So far as allocative efficiency is concerned the majority of the farms are found to be under-users of the endogenous inputs, viz., fertiliser, manure, human and bullock labour.

description: This deliverable analyses requirements from multiple areas of the project, such as the technical and operational requirements drawn from (i) the scientific community, (ii) objectives and constraints of the overall reference architecture, (iii) the governance, management and human resources, and (iv) the legal and ethical policies and regulations, to produce a comprehensive Data Management Plan (DMP) for the future SLICES research infrastructure (SLICES-RI). The DMP provides policies and protocols on how data is governed and managed and how it becomes accessible to other infrastructures and systems. Our approach includes decisions drawn from research and best practices in other infrastructures/systems and are often backed up by appropriate statistics. The deliverable also incorporates recommendations by external projects, such as EOSC and NGI, and adopts well-established principles, such as FAIR, to maximise interoperability and collaboration with external infrastructures/systems. To ensure interoperability, we placed particular emphasis on the design of metadata, since they are essential to enable reuse, facilitate interoperability and maximise impact. A number of well-known metadata schema standards that are applicable for the purposes of the project have been studied and evaluated, leading to the decision to adopt one of the predominant ones. This is further expanded to accommodate the unique characteristics and peculiarities of SLICES. The analysis presented in this deliverable also provides input to various parts of the project, such as the reference architecture and services provided, governance analysis, integration and interoperability with EOSC infrastructure and services and relations with international testbeds. This is the first version of the DMP, which will be updated by the end of the project to also reflect the data management policy in the future SLICES-RI project. Furthermore, the DMP will be aligned with deliverable D7.1, which will fully define the Ethical issues concerning data sharing and compliance with the General Data Protection Regulation (GDPR). Finally, we also present the Data Management Plan for SLICES-DS.

description: The ATLAS detector at the LHC recorded 0.49nb$^{-1}$ of Pb+Pb collisions and 25pb$^{-1}$ of $pp$ collisions, both at the center-of-mass energy 5.02TeV per nucleon pair. Recently, ATLAS also recorded 3$μ$b$^{-1}$ of Xe+Xe collisions at the center-of-mass energy 5.44TeV, which provides a new opportunity to study the system-size dependence of the charged-hadron production in heavy-ion collisions. The large acceptance of the ATLAS detector allows to measure the spectra of charged hadrons in a wide range of pseudorapidity and transverse momentum. The nuclear modification factors $R_\mathrm{AA}$ are constructed as a ratio of the spectra measured in Pb+Pb or Xe+Xe collisions to that measured in $pp$ collisions. The $R_\mathrm{AA}$ obtained in the two systems are presented for different centrality intervals and the results are discussed.

description: The occurrence of haloacetic acids (HAAs) was studied in the drinking water samples from Gharbiya governorate water treatment plants and its water supply network that served more than 5 million people. Drinking water disinfection by-products are formed when a disinfectant reacts with natural organic matter and/or bromide/iodide present in a raw water source. Trihalomethanes and haloacetic acids are the two most prevalent classes of DBPs and are regulated by the US Environmental Protection Agency as well as being subject to World Health Organization guidelines due to their potential health risk. Drinking water samples were collected from 4 sites monthly over one year (2017-2018). The aims of the present study are to investigate the levels of HAAs in Gharbiya governorate (middle of Delta Egypt) drinking water. monochloroacetic acid ranged from 6.8 to 32.5 µg/L, dichloroacetic acid ranged from 9.8 to 43.7 µg/L, and the trichloroacetic acid ranged from 6.5 to 31.8 µg/L, the minimum values observed during winter 2018 and the maximum value observed during summer 2017., The HAAs species values were complying with the Egyptian standard (Ministerial Decree No.458/2007) and as well as WHO 2012) standards for drinking water

Productivity Analysis

description: This paper uses farm-level data collected from a sample of 500 households in Hunan province, China, to analyze the impact of hybrid rice on input demand and productivity. Based on regression analyses, it is found that, compared with conventional modern varieties, hybrid rice uses about 4% less labor inputs, 2% less draft animal services, and 6% more chemical fertilizers. The lesser requirements for labor and draft animal services probably arise from hybrid rice's lower seeding rate. Due to heterosis and high seed costs, the use of F1 seed is economized to about one-third to one-fourth that of conventional varieties. Therefore, less labor and animal power is needed for seed-bed preparation and transplanting. It is also found that, given the same level of inputs, the yield advantage of hybrid rice over the conventional modern varieties is about 19%. Because of the productivity potential, hybrid rice is a candidate for the second-generation "Green Revolution" in other parts of Asia.

description: It is well known that the building blocks for state sum models of quantum gravity are given by 6j and 10j symbols. In this work we study the asymptotics of these symbols by using their expressions as group integrals. We carefully describe the measure involved in terms of invariant variables and develop new technics in order to study their asymptotics. Using these technics we compute the asymptotics of the various Euclidean and Lorentzian 6j-symbols. Finally we compute the asymptotic expansion of the 10j symbol which is shown to be non-oscillating in agreement with a recent result of Baez et al. We discuss the physical origin of this behavior and a way to modify the Barrett-Crane model in order to cure this disease.

description: While vertically oriented metal oxide nanowires have been intensely researched for use as electron transport layers (ETLs) in halide perovskite solar cells (HPSCs), horizontal nanowires (oriented roughly parallel to the substrate) have received much less attention despite their higher photonic strength due to overlapping electric and magnetic dipolar Mie resonance modes. Herein, we demonstrate the fabrication of an assembly of horizontally aligned TiO2 nanorods (HATNRs) on FTO substrates via a facile hydrothermal route. The HATNRs are employed as the ETL to achieve 15.03% power conversion efficiency (PCE) in HPSCs which is higher than the PCE of compact TiO2 based devices (10.12%) by a factor of nearly 1.5. A mixed halide, mixed cation organometal perovskite FA0.83MA0.17Pb(Br0.17I0.83)3 with optimized composition is used as the active layer. The excellent refractive index matching between thE....

Separability in farm-household economics: an experiment with linear programming

Year: 1994

description: The assumption of separability between farm-household production and consumption facilitates analysis, but entails several important restrictions. The implications of assuming separability are discussed here in relation to the modelling of a representative Tongan farm-household. Econometric estimation of household demand is coupled with a linear programming (LP) model of farm-household production. When analysing consumer demand, separable farm-household economics is undoubtedly preferable to ignoring the production/ consumption linkages entirely. However, the restrictions which must be imposed on the production side of the separable model are such that a realistic LP solution is unlikely to be obtained. This is likely to be a major deterrent to adopting the separable approach for studies in which the main focus is on production rather than consumption.

description: This article examines the characteristics of and choice among two production technologies in Ethiopian agriculture, one with fertilizer and the other without, using 1989-90 farm-level data. For northwest and central Ethiopia, fertilizer usage determinants are estimated simultaneously with technology-specific production functions. For southern Ethiopia, where fertilizer is rarely used, a single production function is estimated. Three conclusions emerge. First, fertilizer use is not significantly affected by a farm's stocks of capital or land. This is consistent with the fact that fertilizer allocation decisions under the deposed Mengistu regime were politicized to the point where farmers had little control over use. Second, fertilizer is associated with a smaller factor share for cattle and a larger share for land, meaning that those who control land may gain relative to the individual farmers who own cattle as the country develops agriculturally. Third, farms without fertilizer in northwest and central Ethiopia tend to be too small, a problem due to population pressures on the land and communal methods of land allocation. This suggests that land allocation institutions should adjust by distributing land to a smaller but more economically viable number of farmers.

At high temperatures the specific heat and the susceptibility show power law dependence. For $h \to 0$ and at temperatures below the Kondo temperature $T_K$ a two-channel Kondo effect develops characterized by a Wilson ratio 8/3, and a logarithmic divergence of the susceptibility and the linear specific heat coefficient. Finite magnetic field, $h>0$ drives the system to a Fermi liquid fixed point with an unusual Wilson ratio which depends sensitively on $h$.

description: Extensification of agriculture is one of the major factors contributing to the destruction of forests in Africa. In Sudan, such horizontal expansion comes at the expense of land devoted to trees and other vegetation, thereby inducing conditions that are inimical to sustainable agricultural production. Different factors have contributed to extensification. Although high economic returns from crop (mainly sorghum) production was an important factor encouraging extensification of rainfed mechanized farming, other factors outside agriculture have also contributed to that expansion. This paper uses data from eastern Sudan and an acreage response model, to identify the most important factors influencing acreage expansion. Different measures and forms of risk were used in the acreage response model. The paper shows how policies in the energy sector can indirectly influence acreage expansion in the agricultural sector.

description: Aqueous suspensions of cellulose nanocrystals were blended with Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) [PEDOT:PSS], and cast into thin films. The morphology, structure and electrical properties of the resulting nanocomposite thin films were thoroughly characterized. We found that the CNC–PEDOT:PSS blends self-organize into a layered vertical stack with a pitch of 100–200 nm while retaining a continuous percolation network for PEDOT. Atomic force microscopy, dynamic light scattering and multi-angle light scattering measurements confirmed the wrapping of polymer chains around the rod-like CNCs. The blended films exhibited improved molecular ordering of the PEDOT chains with concomitant improvement in the carrier mobility. The remarkable self-organization and enhanced structural order enabled the CNC–PEDOT:PSS blends to exhibit a high conductivity typical of PEDOT …

description: Scintillation light from liquid noble gas in a neutrino or dark matter experiment lies typically within the vacuum ultraviolet (VUV) region and might be strongly absorbed by surrounding materials such as light guides or photomultiplier. Tetraphenyl butadiene (TPB) is a fluorescent material and acts as a wavelength shifter (WLS) which can turn the UV light to the visible light around a peak wavelength of 425 nm, enabling the light signals to be detected easily for physics study. Compared with a traditional TPB coating method using vapor deposition, we propose an alternative technique with a spin coating procedure in order to facilitate the development of neutrino and dark matter detectors. This article introduces how to fabricate the TPB film on acrylics using the spin coating method, reports measurement of sample film thickness and roughness, shows the reemission spectrum, and quantifies the wavelength shifting efficiency (WLSE).

description: The 23 former socialist countries in Central and Eastern Europe (CEE) and the Commonwealth of Independent States (CIS) started the transition in 1989-1990 from a common institutional and organizational heritage, represented by the Soviet agricultural model. Despite the common heritage in agriculture, the reform policies in CEE and CIS diverged from the start, as significant differences emerged between the two groups of countries in legal attitudes to private land ownership, transferability of land, the extent of agricultural privatization and individualization, and restructuring of farms. This divergence in the implementation of agricultural reform has led to divergence in standard development measures: the CEE countries are outpe1forming the CIS countries by growth in GDP and agricultural product since 1992; the productivity of agricultural labor in CEE is generally increasing, and in CIS it is decreasing. While the CIS countries at best can be characterized as reluctant reformers, the CEE countries have achieved significantly higher levels of economic and institutional reform. Better performance in CEE is associated with greater readiness of the governments in these countries to implement a comprehensive package of economic and social reform policies, including more radical land reform and deeper individualization and restructuring of agriculture.© 2001 Elsevier Science B.V.

description: A Berry phase can be added to the wavefunction of an isolated quantum dot by adiabatically modulating a nonuniform electric field along a time-cycle. The dot is tuned close to a three-level degeneracy, which provides a wide range of possibilities of control. We propose to detect the accumulated phase by capacitively coupling the dot to a double-path inteferometer. The effective Hamiltonian for the phase-sensitive coupling is discussed in detail.

description: Seepage under dams can result in high uplift pressure experienced usually under the downstream of the dam which may lead to instability and potentially the failure of the dam. Cut-off walls are the primary solution to minimise the effects caused by the flow of water, as they extend the flow path which results in decreasing seepage, as well as uplift pressure and exit gradient. (Rice & Duncan, 2010) This study aims to research how designing a cut-off wall at an angle under a concrete dam increases its efficiency. The angles will vary from 0° to 180°, progressively increasing at an interval of 30°. Following that, two walls will be designed originating from the same point at the nose of the dam, as well as another design where the walls are under both ends of the structure. The modal analysis will be completed using the finite element geotechnical software – PLAXIS 2D, as it has proved to be extremely precise in discharge analysis specifically (Galavi, 2010). A typical impervious concrete dam will be designed in the program in a uniform soil profile with the only variable being the angle of the cut-off wall and its originating point. This is done to put the attention simply on the discharge value that is obtained from the software. The feasibility of the construction will always be taken into account, as this study intends to complete research by taking a realistic and economic approach. The results show that seepage is smallest when the cut-off wall is positioned at a 60° angle, as in this position water has to travel the furthest distance compared to the other configurations. In terms of uplift pressure, the dam experienced the least pressure when the wall is at 120°. As seepage and uplift pressure are the two main factors playing significant roles in the stability of dams – two combined configurations were introduced into the model in order to minimise both values; one being the addition of the 60° and 120° angle walls originating at both ends of the dam, and the other where the two formerly mentioned walls originated from the same point (the heel of the dam). The configuration where the two walls are constructed under the heel and the toe show a significant decrease in seepage, as well as uplift pressure at the toe. When the two walls are both constructed originating from the same point (heel) – seepage is determined to be lower compared to when only one wall is considered, however a significant reduction in uplift pressure is not present. When taking all data into account, the most feasible, economical and practical solution to decreasing seepage and uplift pressure considerably appears to be the arrangement where a 60° cut-off wall is constructed at the heel of the dam and 120 ° wall at the toe of the dam.

description: This paper describes an econometric assessment of wine market prices for 21 of the Crus Classes chateaux in the Bordeaux region of France. The model developed in the analysis attempts to define the relationship between factors that influence wine quality and those that influence wine prices. Characteristics of the models are: (1) climate influences on grape composition (acid and sugar levels), (2) grape composition influences on market prices, (3) subjective quality evaluations (Parker-points) on market prices, and ( 4) the effects of age of the wine on market prices. The results indicate that composition levels ofMerlot-dominated wines are more climate sensitive than those from Cabernet Sauvignon-dominated wines. Overall, warm, dry summers result in high sugar and low acid levels at harvest which in turn lead to higher quality wines. Wine market price sensitivity to Parker-point ratings indicates that properties with high Cabernet Sauvignon-dominated wines are highly dependent on the external ratings while Merlot-dominated wines have a decreased rating sensitivity. Smaller properties tend to gain over proportionally from high ratings indicating great jumps in price from year to year. Additionally, chateaux that have experienced high ratings for past vintages exhibit great sensitivity to point steps in ratings for current vintages. Aging has a positive effect on Bordeaux wine pricing. This is due to the increasing maturity as well as the increasing absolute scarcity. Absolute scarcity of product is expressed by the size of the property, with small properties producing less per vintage and therefore having less in the market. Additionally, Merlot-dorninated wines exhibit more maturing potential and profit more from aging than Cabernet Sauvignon-dominated wines. Average per chateau real annual profit ranges from 1 to 10%. High levels of grape ripeness, absolute scarcity, and smaller properties that are dominated by Merlot in their blend lead to the highest profits. Forecasts for a vintage not yet on the market indicates that 1995 is better than 1994 for both Cabernet Sauvignon and Merlot-dominated wines, but that 1996 and 1997 are not as good as 1995, especially for Merlot-dominated wines.© 2001 Elsevier Science B.V.

description: The existence of $^{12}{\rm C} + {}^{16}{\rm O}$ molecular resonances at sub-barrier energy has been a significant problem in nuclear astrophysics because they strongly affect the $^{12}{\rm C} + {}^{16}{\rm O}$ fusion reaction rate in type Ia supernovae and heavy stars. However, experimental surveys have been limited to 4~MeV and cannot access the deep sub-barrier energy due to a very small fusion cross section. Here we predict a couple of resonances with $J^π=0^+$, $2^+$, and $4^+$ in the deep sub-barrier energy based on the antisymmetrized molecular dynamics calculation that reproduces the known resonances and low-lying spectrum of $^{28}{\rm Si}$.

description: Within the framework of Ginzburg-Landau theory we study the rich variety of interfacial phase transitions in twinning-plane superconductors. We show that the phase behaviour strongly depends on the transparency of the twinning plane for electrons measured by means of the coupling parameter α_TP. By analyzing the solutions of the Ginzburg-Landau equations in the limit of perfectly transparent twinning planes, we predict a first-order interface delocalization transition for all type-I materials. We further perform a detailed study of the other limit in which the twinning plane is opaque. The phase diagram proves to be very rich and fundamentally different from the transparent case, recovering many of the results for a system with an external surface. In particular both first-order and critical delocalization transitions are found to be possible, accompanied by a first-order depinning transition. We provide a comparison with experimental results and discuss the relevance of our findings for type-II materials.

description: On-chip microlaser sources in the blue constitute an important building block for complex integrated photonic circuits on silicon. We have developed photonic circuits operating in the blue spectral range based on microdisks and bus waveguides in III-nitride on silicon. We report on the interplay between microdisk-waveguide coupling and its optical properties. We observe critical coupling and phase matching, i.e. the most efficient energy transfer scheme, for very short gap sizes and thin waveguides (g = 45 nm and w = 170 nm) in the spontaneous emission regime. Whispering gallery mode lasing is demonstrated for a wide range of parameters with a strong dependence of the threshold on the loaded quality factor. We show the dependence and high sensitivity of the output signal on the coupling. Lastly, we observe the impact of processing on the tuning of mode resonances due to the very short coupling distances. Such small footprint on-chip integrated microlasers providing maximum energy transfer into a photonic circuit have important potential applications for visible-light communication and lab-on-chip bio-sensors.

description: Single‐atom catalysts (SACs) aim at bridging the gap between homogeneous and heterogeneous catalysis. The challenge is the development of materials with ligands enabling coordination of metal atoms in different valence states, and preventing leaching or nanoparticle formation. Graphene functionalized with nitrile groups (cyanographene) is herein employed for the robust coordination of Cu(II) ions, which are partially reduced to Cu(I) due to graphene‐induced charge transfer. Inspired by nature's selection of Cu(I) in enzymes for oxygen activation, this 2D mixed‐valence SAC performs flawlessly in two O2‐mediated reactions: the oxidative coupling of amines and the oxidation of benzylic CH bonds toward high‐value pharmaceutical synthons. High conversions (up to 98%), selectivities (up to 99%), and recyclability are attained with very low metal loadings in the reaction. The synergistic effect of Cu(II) and Cu(I) is the essential part in the reaction mechanism. The developed strategy opens the door to a broad portfolio of other SACs via their coordination to various functional groups of graphene, as demonstrated by successful entrapment of FeIII/FeII single atoms to carboxy‐graphene.
