description: Au bout d’une décennie de Nouvelle Politique Agricole, l’économie arachidière se trouve dans une situation de morosité sans précédent. Et comme l'a bien reconnu le rapport du Groupe de Reflexion Stratégique, qui a été mis sur pied par le ministre de l'agriculture, il faudra, pour relancer le secteur, rompre avec les approches productivistes, qui consistent à vouloir augmenter les surfaces et les productions sans trop se soucier de la rentabilité au niveau de tous les stades de la filière. Les politiques de prix et de commercialisation font partie des facteurs principaux qui affectent les niveau de rentabilité et de compétitivité au sein de la filière arachidière. La réforme de ces politiques devra donc nécessairement faire partie du débat sur la relance du secteur. Le présent papier se propose d'analyser les effets d'une éventuelle réforme de ces politiques sur les incitations à la production et la rentabilité dans le secteur de transformation. Les résultats indiquent qu'une libéralilsation des marchés, sans une réduction substantielle des coûts de commercialisation observés dans le secteur privé, pourrait avoir des conséquences sérieuses pour la compétitivité du secteur de transformation. D'où le besoin d'accorder suffisamment d'attention en cas de libéralisation à l'emergence d'un secteur privé de commercialisation competitif et efficient. Les résultats indiquent également qu'une libéralisation effective des politiques de prix et de commercialisation doit nécessairement aller de pair avec une amélioration de la productivité et une forte réduction des coûts unitaires de production dans le secteur de transformation. Force est donce de reconnaître que le problème de la filière est loin d'être uniquement un problème de prix et de système de commercialisation ou de production.

description: Purpose: Nowadays, most cases of pneumococcal community-acquired pneumonia (PCAP) are diagnosed by positive urinary antigen. Our aims were to analyse process of care in patients hospitalised with non-bacteremic PCAP (NB-PCAP) and identify factors associated with poor outcome (PO) in this population. Methods: We conducted a prospective study, including patients hospitalised for NB-PCAP (positive urinary antigen and negative blood culture) over a 15 year period. We performed multivariate analysis of predisposing factors for PO, defined as need for mechanical ventilation and/or shock and/or in-hospital death. Results: Of the 638 patients included, 4.1% died in hospital and 12.8% had PO. Host-related factors were similar in patients with and without PO, but patients with PO had higher illness severity on admission. Adjusted analysis revealed the following independent factors associated with PO: being a nursing home resident (OR: 6.156; 95% CI: 1.827–20.750; p = .003), respiratory rate ≥30 breaths/min (OR: 3.030; 95% CI: 1.554–5.910; p = .001), systolic blood pressure <90 mmHg (OR: 4.789; 95% CI: 1.967–11.660; p = .001), diastolic blood pressure <60 mmHg (OR: 2.820; 95% CI: 1.329–5.986; p = .007), pulse rate ≥125 beats/min (OR: 3.476; 95% CI: 1.607–7.518; p = .002), pH <7.35 (OR: 9.323; 95% CI: 3.680–23.622; p p p = .009). The area under the curve for predicting PO was 0.890 (95% CI: 0.851–0.929). Conclusions: Since patients with PO seem different and had worse in-hospital course, we identified eight independent risk factors for PO measurable on admission.

description: Trends for major fisheries products are evaluated for the past two decades, using aggregate annual data. Major changes have been propelled by income growth, changes in preferences and health concerns about meat in developed countries, leading to increased consumption of high-valued fisheries items such as shell and filet fish. Developing countries, especially East Asia, are rapidly increasing consumption of lower valued fishery items, and fish-culture is becoming an increasingly important source of food and exports. Developed countries accounted for 85 percent of net world fish imports in 1994, mostly at the high end of the value spectrum, from about twenty countries. In the ten years preceding 1993, the net value of fisheries exports from developing countries went from less than a third of net developing country exports of sugar, beverage crops and tropical specialty products combined, to a level exceeding that total. While real fish prices have remained relatively stable since 1970, real beef prices have declined by 300 percent, suggesting that a rally in meat prices would further accentuate the shift to fish. Current evidence suggests a 15 percent relative strengthening of fish prices to beef through 2020.

description: In this paper, we obtain the necessary and sufficient condition that two knot projections are related by a finite sequence of the first and second flat Reidemeister moves (Theorem 1). We also consider an equivalence relation that is called weak (1, 3) homotopy. This equivalence relation occurs by the first flat Reidemeister move and one of the third flat Reidemeister moves. We introduce a map sending weak (1, 3) homotopy classes to knot isotopy classes (Sec. 3). Using the map, we determine which knot projections are trivialized under weak (1, 3) homotopy (Corollary 3).

description: The well-known Bean critical state equations in general are not sufficient to describe the critical state of type-II superconductors when the sample shape is not symmetric. We show how one can find the critical state in superconductors of arbitrary shape. Analyzing a simple example of nonsymmetry, we demonstrate that in the general case, a perturbation of the current distribution in the critical state propagates into the sample smoothly in a diffusive way. This is in contrast to the usual Bean critical state where the current distribution changes abruptly at a narrow front.

description: As a model of a novel superconductor Na_xCoO_2\cdotyH_2O, a single-band t-J model on a triangular lattice is studied, using a variational Monte Carlo method. We calculate the energies of various superconducting (SC) states, changing the doping rate δand sign of t for small J/|t|. Symmetries of s, d, and d+id (p+ip and f) waves are taken up as candidates for singlet (triplet) pairing. In addition, the possibility of Nagaoka ferromagnetism and inhomogeneous phases is considered. It is revealed that, among the SC states, the d+id wave always has the lowest energy, which result supports previous mean-field studies. There is no possibility of triplet pairing, although the f-wave state becomes stable against a normal state in a special case (δ=0.5 and t<0). For t<0, the complete ferromagnetic state is dominant in a wide range of δand J/|t|, which covers the realistic parameter region of superconductivity.

title: Foreign direct investment and South-South cooperation : negotiating space, place and power within Chinese FDI in South Africa
Creators: name: O'Brien, Liam M
Publisher: name: University of St Andrews
Year: 2019

description: Chinese Foreign Direct Investment (FDI) in South Africa is indicative of a two-fold transformation in the contemporary development landscape: the rise of South-South Cooperation (SSC) and a re-centering of economic growth as a driver of development. However, to attract investment, and accrue developmental opportunities, hosts must first offer an enabling environment. Where an enabling environment does not presently exist, it must be actively produced. This is undertaken by a range of actors and against multiple and contested priorities. FDI, therefore, cannot be understood without an appreciation of the intimate, yet understudied, negotiations over space and place. Through the use of semi-structured interviews, field observations, and documentary analysis at the location of three differing Chinese investments in South Africa – including a Chinese SOE within an economic zone, a mining partnership with a traditional rural community, and a ‘new city’ development led by a private Chinese investor – the thesis asks how space and place is produced to support investment, the location of agency, and the limits realities place upon the role of FDI in SSC. Findings show that, whilst space and place were often co-produced and actively negotiated between host and investors, motivations and priorities were aligned to a need to provide spaces of comparative and competitive difference within wider international political economy. The structural production of space and place in this way created new dependencies and further uneven development. This had implications for a host ability to develop in accordance with their own values and objectives. Conclusions suggest FDI in the development landscape limits the radical potential of SSC. The thesis applies geographic theory in a context not yet seen and, through bringing together Chinese and South African voices in a single study, contributes original empirical data from underrepresented voices in scholarship on China-Africa relations.

description: Microlending, where a bank lends to a small group of people without credit histories, began with the Grameen Bank in Bangladesh, and is widely seen as the creation of Muhammad Yunus, who received the Nobel Peace Prize in recognition of his largely successful efforts. Since that time the modeling of microlending has received a fair amount of academic attention. One of the issues not yet addressed in full detail, however, is the issue of the size of the group. Some attention has nevertheless been paid using an experimental and game theory approach. We, instead, take a mathematical approach to the issue of an optimal group size, where the goal is to minimize the probability of default of the group. To do this, one has to create a model with interacting forces, and to make precise the hypotheses of the model. We show that the original choice of Muhammad Yunus, of a group size of five people, is, under the right, and, we believe, reasonable hypotheses, either close to optimal, or even at times exactly optimal, i.e., the optimal group size is indeed five people.

description: The revised Enskog approximation for a fluid of hard spheres which lose energy upon collision is discussed for the case that the energy is lost from the normal component of the velocity at collision but is otherwise arbitrary. Granular fluids with a velocity-dependent coefficient of restitution are an important special case covered by this model. A normal solution to the Enskog equation is developed using the Chapman-Enskog expansion. The lowest order solution describes the general homogeneous cooling state and a generating function formalism is introduced for the determination of the distribution function. The first order solution, evaluated in the lowest Sonine approximation, provides estimates for the transport coefficients for the Navier-Stokes hydrodynamic description. All calculations are performed in an arbitrary number of dimensions.

description: Several different transport processes, such as heat transport, momentum transport and charge transport, may take place at the same time in the quark-gluon plasma (QGP). The corresponding transport coefficients are heat conductivity, shear viscosity and electric conductivity respectively. In the present paper, we will study the color-electric conductivity of the QGP in presence of shear viscosity, which is focused on the connection between the charge transport and the momentum transport. To achieve that goal, we solve the viscous chromohydrodynamic equations which are obtained from the QGP kinetic theory associated with the distribution function modified by shear viscosity. According to the solved color fluctuations of hydrodynamic quantities we obtain the induced color current through which the color-electric conductivity is derived. Then we study viscous effects on the color-electric conductivity. In the viscous chromohydrodynamic approach, the conductivity properties of the QGP are mainly demonstrated by the longitudinal part of the color-electric conductivity. Shear viscosity has an appreciable impact on real and imaginary parts of the color-electric conductivity in some frequency region.

description: Work from home is a model or work agreement where employees get the flexibility to work in terms of place and time of work with the help of telecommunications technology, in other words, the activities of traveling to the office or workplace are replaced by telecommunications relations,conclude that in a pandemic like this, we must participate in social cooperation to stay at home if there is no urgent need, this can minimize the spread of viruses that can be infected if the community is crowded together. But it cannot be denied, people still need to work to meet the needs of their daily lives, therefore the government decided to carry out work from home where workers do all their work activities at home. Work from home is the solution to these problems, compared to if we continue to work in an office that can potentially expand the spread of the virus. Work from home is the best solution available today if we have to keep working in the pandemic, with work from home we have helped not to make the spread of COVID-19 more widespread. So, work from home is far better than work from office when viewed from the point of view when there is a pandemic.
Electroosmotic flow in small-scale channels induced by surface-acoustic waves

Year: 2020

description: Numerical simulations of the Navier-Stokes, Nernst-Planck, and the Poisson equations are employed to describe the transport processes in an aqueous electrolyte in a parallel-plate nanochannel, where surface-acoustic waves (SAWs) are standing or traveling along (piezo-active) channel walls. It is found that -- in addition to the conventional acoustic streaming flow -- a time-averaged electroosmotic flow is induced. Employing the stream function-vorticity formulation, it is shown that the Maxwell stress term causes an electroosmotic propulsion that is qualitatively identical to the one discussed in the context of alternating current (AC) electroosmosis (EOF). Differences arise mainly due to the high actuation frequencies of SAWs, which are in the MHz range rather than in the kHz regime typical for ACEOF. Moreover, the instantaneous spatial periodicity of the EOF in the travel direction of the SAW is intrinsically linked to the dispersion relation of the latter rather than a free geometric parameter. This leads to a specific frequency band where an EOF of sizable magnitude can be found. On the low frequency end, the ratio between the electric double layer (EDL) thickness and the SAW wavelength becomes extremely small so that the net force leading to a non-vanishing time-averaged flow becomes equally small. On the high frequency end, the RC time of the EDL is much larger than the inverse of the SAW frequency leading to a vanishing effective charge density of the EDL. For a parallel-plate channel, the EOF can be maximized by using two SAWs on both channel walls that have the same frequency but are phase-shifted by $180^\circ$. It appears that the SAW-EOF is the dominant pumping mechanism for such a scenario. The proposed actuation might be a viable alternative for driving liquid electrolytes through narrow ducts and channels, without the need for electric interconnects and electrodes.

description: The erroneous prediction of the speed of light in dispersive media has been looked upon historically as unequivocal proof that Newton's corpuscular theory is incorrect. Examination of his arguments shows that they were only directly applicable to the momentum of photons, however, leaving open the possibility that the cause of his mistake was the unavailability of a suitable mechanical theory to enable a correct light speed prediction, rather than his use of a particle model. It is shown that Hamilton's canonical equations of motion remove Newton's error quantitatively, and also lead to the most basic formulas of quantum mechanics without reference to any of the pioneering experiments of the late nineteenth century. An alternative formulation of the wave-particle duality principle is then suggested which allows the phenomena of interference and diffraction to be understood in terms of statistical distributions of large populations of photons or other particles.

description: Malawi is among the most poor and food insecure countries in the world according to UNDP’s Human Development Report (2004). Agriculture is the driving force of the economy of Malawi and the backbone to food security. The government of Malawi introduced a program called One Village One Product (OVOP) in 2003 whose major objective is poverty reduction by bringing economic independence into the communities. However, no effort had been made to evaluate the program and its activities hence creating an information gap. This study was therefore conducted in OVOP operation area of Bvumbwe in Thyolo district, Malawi to assess the impact of One Village One Product (OVOP) program on households’ farm income and its implications on food security. Primary data was collected from a total of 80 beneficiaries and non-beneficiaries of One Village One Product (OVOP) program. Out of the 52 beneficiaries, 40 were systematically selected and the other 40 was collected randomly from the non-beneficiaries in the area. The data were collected in April 2006 by the use of structured questionnaires and focus group discussion guide. Data was analyzed using descriptive statistics, chi – squares, t-test and the Ordinary Least Squared Technique of multiple regression method. A likert scaling technique was used to rate farmers’ perception of the effect of OVOP on farm activities. The results indicated that there was a significant difference in the levels of household farm income between beneficiaries and non beneficiaries of OVOP. The OVOP beneficiaries were found to be better off in terms of household food security through increased food basket, enterprise diversification and food access which was attained through higher farm income. However, farmers’ socio-economic characteristics did not adequately explain the disparity in household farm income. This implies that there are some other factors that are closely associated with agricultural production and participation in programs such as OVOP, which may require further investigation. Participation in OVOP and household size were found to be positively associated with household farm income. The study recommends expansion of the OVOP program to target the vulnerable groups and government intervention fast track infrastructural development in the area to facilitate value addition, processing and storage facilities.

description: This paper shares an experience of applying the barycentric subdivision method for designing andconstructing a rope-made steel-framed pavilion structure for Dubai Design Week 2018. Barycentricsubdivision subdivides a polygon into multiple triangles, and we used this geometric process iterativelywith each cell of a triangular grid that eventually resulted in a complex pattern resembling the Islamicpattern “mashrabiyas” that is frequently seen in the Arab region. This geometric outcome helped us todesign the mashrabiya pavilion targeted for 2018’s Dubai Design Week event which mainly exhibitssuch designs that display contemporary expressions rooted or emerged from regional traditions. Weapplied our barycentric-subdivision-based mashrabiya-like pattern to a hypar (hyperbolic paraboloid)structure for making the proposed pavilion structure. We used ropes for weaving the mashrabiyainspiredweb. We conducted structural analysis to ensure the structural feasibility and strength of thepavilion for the real-world installation. This paper outlines the structural analysis of the pavilion briefly.After a series of analysis, we constructed the pavilion at the University campus by the students as a partof their hands-on design workshop exercise, and finally moved and installed it at the main venue DubaiDesign District for the exhibition. The whole workflow of the design and construction process wasstrategically designed so that students can acquire studio-based learning as well as off-studio hands-onconstruction experience targeting for a prestigious exhibition.

description: SmO thin film is a new Kondo system showing a resistivity upturn around 10 K and was theoretically proposed to have a topologically nontrivial band structure. We have performed hard x-ray and soft x-ray photoemission spectroscopy to elucidate the electronic structure of SmO. From the Sm 3$d$ core-level spectra, we have estimated the valence of Sm to be $\sim$2.96, proving that the Sm has a mixed valence. The valence-band photoemission spectra exhibit a clear Fermi edge originating from the Sm 5$d$-derived band. The present finding is consistent with the theory suggesting a possible topological state in SmO and show that rare-earth monoxides or their heterostructures can be a new playground for the interplay of strong electron correlation and spin-orbit coupling.

description: We have derived ages, metallicities and enhanced-element ratios [alpha/Fe] for a sample of 83 early-type galaxies essentially in groups, the field or isolated objects. The stellar population properties derived for each galaxy corresponds to the nuclear r_e/8 aperture extraction. The median age found for Es is 5.8 +- 0.6 Gyr and the average metallicity is +0.37 +- 0.03 dex. For S0s, the median age is 3.0 +- 0.6 Gyr and [Z/H] = 0.53 +- 0.04 dex. We compare the distribution of our galaxies in the Hbeta-[MgFe] diagram with Fornax galaxies. Our elliptical galaxies are 3-4 Gyr younger than Es in the Fornax cluster. We find that the galaxies lie in a plane defined by [Z/H] = 0.99 log sigma_0 - 0.46 log Age - 1.60. More massive (larger sigma_0) and older galaxies present, on average, large [alpha/Fe] values, and therefore, must have undergone shorter star-formation timescales. Comparing group against field/isolated galaxies, it is not clear that environment plays an important role in determining their stellar population history. In particular, our isolated galaxies show ages differing in more than 8 Gyr. Finally we explore our large spectral coverage to derive log(O/H) metallicity from the N2 indicator and compare it with model-dependent [Z/H]. We find that the O/H abundances are similar for all galaxies, and we can interpret it as if most chemical evolution has already finished in them.

description: We investigate the local and global dynamics of two 1-Dimensional (1D) Hamiltonian lattices whose inter-particle forces are derived from non-analytic potentials. In particular, we study the dynamics of a model governed by a "graphene-type" force law and one inspired by Hollomon's law describing "work-hardening" effects in certain elastic materials. Our main aim is to show that, although similarities with the analytic case exist, some of the local and global stability properties of non-analytic potentials are very different than those encountered in systems with polynomial interactions, as in the case of 1D Fermi-Pasta-Ulam-Tsingou (FPUT) lattices. Our approach is to study the motion in the neighborhood of simple periodic orbits representing continuations of normal modes of the corresponding linear system, as the number of particles $N$ and the total energy $E$ are increased. We find that the graphene-type model is remarkably stable up to escape energy levels where breakdown is expected, while the Hollomon lattice never breaks, yet is unstable at low energies and only attains stability at energies where the harmonic force becomes dominant. We suggest that, since our results hold for large $N$, it would be interesting to study analogous phenomena in the continuum limit where 1D lattices become strings.

description: Work from home is a model or work agreement where employees get the flexibility to work in terms of place and time of work with the help of telecommunications technology, in other words, the activities of traveling to the office or workplace are replaced by telecommunications relations,conclude that in a pandemic like this, we must participate in social cooperation to stay at home if there is no urgent need, this can minimize the spread of viruses that can be infected if the community is crowded together. But it cannot be denied, people still need to work to meet the needs of their daily lives, therefore the government decided to carry out work from home where workers do all their work activities at home. Work from home is the solution to these problems, compared to if we continue to work in an office that can potentially expand the spread of the virus. Work from home is the best solution available today if we have to keep working in the pandemic, with work from home we have helped not to make the spread of COVID-19 more widespread. So, work from home is far better than work from office when viewed from the point of view when there is a pandemic.

description: We use a deformed QRPA formalism to describe simultaneously the energy distributions of the single beta Gamow-Teller strength and the two-neutrino double beta decay matrix elements. Calculations are performed in a series of double beta decay partners with A = 48, 76, 82, 96, 100, 116, 128, 130, 136 and 150, using deformed Woods-Saxon potentials and deformed Skyrme Hartree-Fock mean fields. The formalism includes a quasiparticle deformed basis and residual spin-isospin forces in the particle-hole and particle-particle channels. We discuss the sensitivity of the parent and daughter Gamow-Teller strength distributions in single beta decay, as well as the sensitivity of the double beta decay matrix elements to the deformed mean field and to the residual interactions. Nuclear deformation is found to be a mechanism of suppression of the two-neutrino double beta decay. The double beta decay matrix elements are found to have maximum values for about equal deformations of parent and daughter nuclei. They decrease rapidly when differences in deformations increase. We remark the importance of a proper simultaneous description of both double beta decay and single Gamow-Teller strength distributions. Finally, we conclude that for further progress in the field it would be useful to improve and complete the experimental information on the studied Gamow-Teller strengths and nuclear deformations.

description: A floor and trade policy in Renewable Identification Numbers (RINs) is the market mechanism by which U.S. biofuel consumption mandates are met. A conceptual model is developed to study the impact of RINs on stimulating investment in cellulosic biofuel refineries. In a two-period framework, we compare the first-period investment level (FIL) in three scenarios: (1) laissez-faire, (2) RINs under a nonwaivable mandate (NWM) policy, and (3) RINs under a waivable mandate (WM) policy. Results show that when firm-level marginal costs are constants, then RINs under WM policy do not stimulate FIL but they do increase the expected profit of more efficient investors. When firm-level marginal costs are not constants, however, RINs under WM policy stimulate FIL. RINs under NWM policy may or may not stimulate FIL, depending on the distribution of second-period cellulosic biofuel prices and on firm-level marginal costs.

description: So there are so many benefits that we can get by work from home when this pandemic. because we have to listen what the government says to in order to reduce the widespread spread of the COVID-19 outbreak, work is a necessity for everyone because if we don't work then we can't eat. With this we must find a solution so that we can continue to work and get a salary in a way that is working from home in order to reduce the spread of this virus. This makes work from home very helpful in reducing the spread of covid-19 virus and work from home is better than work from office

description: We discuss two properties making a deterministic algorithm suitable to generate a pseudo random sequence of numbers: high value of Kolmogorov-Sinai entropy and high-dimensionality. We propose the multi dimensional Anosov symplectic (cat) map as a Pseudo Random Number Generator. We show what chaotic features of this map are useful for generating Pseudo Random Numbers and investigate numerically which of them survive in the discrete version of the map. Testing and comparisons with other generators are performed.

description: We study the dynamical generation and storage of spin squeezed states, as well as more entangled states up to macroscopic superpositions, in a system composed of a few ultra-cold atoms trapped in a one-dimensional optical lattice. The system, initially in the superfluid phase with each atom in a superposition of two internal states, is first dynamically entangled by atom-atom interactions then adiabatically brought to the Mott-insulator phase with one atom per site where the quantum correlations are stored. Exact numerical diagonalization allows us to explore the structure of the stored states by looking at various correlation functions, on site and between different sites, both at zero temperature and at finite temperature, as it could be done in an experiment with a quantum-gas microscope.

description: We study the stability and structure of vortices emerging in two-dimensional quantum dots in high magnetic fields. Our results obtained with exact diagonalization and density-functional calculations show that vortex structures can be found in various confining potentials. In non-symmetric external potentials we find off-electron vortices that are localized giving rise to charge deficiency or holes in the electron density with rotating currents around them. We discuss the role of quantum fluctuations and show that vortex formation is observable in the energetics of the system. Our findings suggest that vortices can be used to characterize the solutions in high magnetic fields, giving insight into the underlying internal structure of the electronic wave function.
