description: Smallholder farmers in Nigeria with total farm holdings of less than 5 hectares constitute about 70 percent of the farming population and produce most of the food crops and thereby contribute to food security and poverty reduction. Inspite of their contributions, they still have the challenges of globalization and liberalization which require producers compete in the markets hence commercial agriculture has come to the rescue which theoretical terms is associated with market oriented production. The objective of this paper is to review the environmental impacts of commercial agriculture in Nigeria. It presents an overview of the Nigeria’s commercial agriculture, its prospects and opportunities. It also highlights the hidden (environmental, economic and indirect) costs of commercial agriculture. The appropriate policies and prospects that can enhance rapid development of commercial agriculture were also mentioned. The paper recommends that the Nigerian authority should create the enabling environment for favourable macroeconomic policies, competent government administration, adequate infrastructure, political stability and a strong human capital base to move the country from subsistence level to commercial agriculture.

description: In this work we compute the spectra, waveforms and total scalar energy radiated during the radial infall of a small test particle coupled to a scalar field into a $d$-dimensional Schwarzschild-anti-de Sitter black hole. We focus on $d=4, 5$ and 7, extending the analysis we have done for $d=3$. For small black holes, the spectra peaks strongly at a frequency $ω\sim d-1$, which is the lowest pure anti-de Sitter (AdS) mode. The waveform vanishes exponentially as $t \to \infty$, and this exponential decay is governed entirely by the lowest quasinormal frequency. This collision process is interesting from the point of view of the dynamics itself in relation to the possibility of manufacturing black holes at LHC within the brane world scenario, and from the point of view of the AdS/CFT conjecture, since the scalar field can represent the string theory dilaton, and 4, 5, 7 are dimensions of interest for the AdS/CFT correspondence.

description: Anisotropic Kepler problem is investigated by perturbation method in both classical and quantum mechanics. In classical mechanics, due to the singularity of the potential, global diffusion in phase space occurs at an arbitrarily small perturbation parameter. In quantum mechanics, the singularity induces a large transition amplitude between quasi degenerate eigen states, which generically decays as $\hbar$ in the semi-classical limit.

description: Irrigated agriculture commercialization is a necessary step towards realizing Nigeria’s goal of poverty reduction and rural development. Commercial irrigation farming in this paper is taken to mean producing above subsistence and utilizing farm resources efficiently. This paper is a case study in the Lower Anambra Irrigation Project South-Eastern Nigeria. A sample of 143 farmers in the scheme, was selected for interview with well structured questionnaire. A focus group discussion with key farmers and River basin development staff was also used to elicit information. Descriptive statistics were used to analyse the socio economic characteristics of the farmers, while a Cobb- Douglas production function analysis was used to ascertain productivity of resources used in the farm. The results show that given the farmer characteristics, and resource efficiencies, opportunity for commercialization of irrigated agriculture in the public sector irrigation scheme exists.

description: Manifest gauge-invariance requires that observable states in the standard-model are described by composite operators, which involve additional Higgs contributions beyond perturbation theory. This field-theoretical effect has been confirmed in lattice simulations. It should also be experimentally accessible at high enough precision. Here a few estimates for such signatures at current and future collider experiments will be discussed.

description: We study the problem of drawing samples from a logconcave distribution truncated on a polytope, motivated by computational challenges in Bayesian statistical models with indicator variables, such as probit regression. Building on interior point methods and the Dikin walk for sampling from uniform distributions, we analyze the mixing time of regularized Dikin walks. Our contributions are threefold. First, for a logconcave and log-smooth distribution with condition number $κ$, truncated on a polytope in $\mathbb{R}^n$ defined with $m$ linear constraints, we prove that the soft-threshold Dikin walk mixes in $\widetilde{O}((m+κ)n)$ iterations from a warm initialization. It improves upon prior work which required the polytope to be bounded and involved a bound dependent on the radius of the bounded region. Moreover, we introduce the regularized Dikin walk using Lewis weights for approximating the John ellipsoid. We show that it mixes in $\widetilde{O}((n^{2.5}+κn)$. Second, we extend the mixing time guarantees mentioned above to weakly log-concave distributions truncated on polytopes, provided that they have a finite covariance matrix. Third, going beyond worst-case mixing time analysis, we demonstrate that soft-threshold Dikin walk can mix significantly faster when only a limited number of constraints intersect the high-probability mass of the distribution, improving the $\widetilde{O}((m+κ)n)$ upper bound to $\widetilde{O}(m + κn)$. Additionally, per-iteration complexity of regularized Dikin walk and ways to generate a warm initialization are discussed to facilitate practical implementation.

Productivity Analysis

description: This paper traces the trajectories of successful commercial smallholders operating under differing sets of market institutions. Analysis focuses on maize, cotton and horticulture, three widely marketed crops with strikingly different market institutions. Maize receives intensive government input and marketing support. In contrast, cotton relies primarily on private contract farming schemes, while horticulture enjoys no large-scale institutional support from either the public or private sectors. Using a mix of quantitative and qualitative methods, the analysis aims to identify personal characteristics and institutional factors that enable smallholder transitions to high-productivity commercial agriculture. The study concludes that only a small minority of Zambian smallholder farmers succeed in transitioning to high-productivity, high-volume commercial agriculture. Only about 20% of cotton farmers and less than 5% of maize and horticulture farmers succeed as top-tier commercial growers. By tracing the long-term agricultural trajectories of successful commercial smallholders, the paper identifies two broad agricultural pathways out of poverty. The low road, exemplified by cotton production, involves a two-generation transition via low-value but with well-structured markets. The more restrictive high road, epitomized by horticulture production, offers a steeper ascent, enabling prosperity within a single generation, but requires commensurately higher levels of financing, management and risk.

description: The differential cross section for scattering of a Dirac particle in a black hole background is found. The result is the gravitational analog of the Mott formula for scattering in a Coulomb background. The equivalence principle is neatly embodied in the cross section, which depends only on the incident velocity, and not the particle mass. The low angle limit agrees with classical calculations based on the geodesic equation. The calculation employs a well-defined iterative scheme which can be extended to higher orders. Repeating the calculation in different gauges shows that our result for the cross section is gauge-invariant and highlights the issues involved in setting up a sensible iterative scheme.

description: L’informatrice est âgée de 33 ans, mère de deux enfants, et elle est professeur dans un lycée technique. Elle débute l’entretien en comparant ses deux grossesses qui se sont bien déroulées. Elle précise que son enfant est né quatre jours après la date prévue de la naissance. Ce fut un accouchement naturel sous péridurale, nommé PDA en allemand. Son mari l’a accompagné dans la salle d‘accouchement car il n’y avait pas de sage-femme disponible. Elle précise qu’on lui a posé sur le ventre l’enfant tout de suite après la naissance et que celui-ci a directement cherché le sein, et qu’il a bien tété une substance à ce moment là. Le placenta et le méconium de l’enfant sont évoqués. La prise en charge des premiers soins de l’enfant est expliquée (changement des couches, toilette). L’informatrice raconte les premiers jours de la vie de son enfant. Au sujet de l’allaitement, une sage-femme spécialisée est venue sensibiliser la mère sur le thème de l’allaitement et les bonnes positions à prendre lors des tétées. La montée de lait a eu lieu le deuxième jour après la naissance. L‘informatrice connaît les deux notions de premier lait ou de colostrum. Elle sait que le celui-ci est important pour l’enfant car il contient des substances immunitaires et précise que le colostrum était déjà visible durant ces derniers mois de grossesse, que son enfant l’a bien consommé et décrit le colostrum comme ayant un aspect jaunâtre et épais. Elle n’y a pas goûté ni au lait maternel d’ailleurs. Elle évoque ensuite son retour à domicile et le passage de la sage-femme pour le suivi. Concernant l’allaitement elle précise que le positionnement de l’enfant est très important pour éviter les douleurs aux seins et énumère ce qu’elle consomme pour favoriser la montée de lait et ce qu’elle évite. L’informatrice fait une comparaison entre l’allaitement de sa fille aîné et son deuxième enfant et dit que son expérience de tire-lait avec sa fille aînée n’avait pas été une réussite. L’allaitement maternel dans un lieu public est abordé. L’informatrice évoque son expérience de la maternité pour ses deux grossesses. A la fin de l’enquête, le thème de la mort subite du nourrisson est évoqué.

description: Future large liquid argon direct dark matter detectors can benefit greatly from an efficient surface background rejection technique. To aid the development of these large scale detectors a test stand, Argon-1, has been constructed at Carleton University, Ottawa, Canada, in the noble liquid detector development lab. It aims to test a novel surface background rejection technique using a thin layer of slow scintillating material at the surface of the vessel. Through pulse-shape discrimination of the slow light from the scintillating layer, events from the surface of the detector can be discriminated from liquid argon events. The detector will be implemented with high-granularity SiPMs for light detection which will be used to accurately identify surface events to characterize the proposed technique. An overview of the technique and the status of the experiment are discussed here.

Consumer/Household Economics

description: This paper uses a novel experimental approach to measure consumer willingness to pay for wine attributes in a hedonic framework. The research design allows us to deal with identification issues resulting from the interaction of demand and supply and to examine the effect of supply-side influences in price data. We employ information from observed wine choices and individual fixed effects to account for consumer heterogeneity and sorting. The effects of controlling for supply and addressing sorting and heterogeneity yield estimates of WTP for wine attributes markedly different than those found by past studies. The results demonstrate that consumer sorting is an important force in product markets and that consumer preferences for unobserved attributes drive valuation differences significantly. For instance, consumers in our sample display greater strength of preference over wine varieties than they do for appellations. It is therefore necessary to interpret results carefully when using valuation data that has been generated in controlled conditions.

description: We use newly constructed data to model and measure agricultural productivity growth and the returns to public agricultural research conducted in Uruguay over the period 1961–2010. We pay attention specifically to the role of levy-based funding under INIA, which was established in 1990. Our results indicate that the creation of INIA was associated with a revitalization of funding for agricultural R&D in Uruguay, which spurred sustained growth in agricultural productivity during the past two decades when productivity growth was stagnating in many other countries. The econometric results were somewhat sensitive to specification choices. The preferred model includes two other variables with common trends, a time-trend variable and a proxy for private research impacts, as well as a variable representing the stock of public agricultural knowledge that entailed a lag distribution with a peak impact at year 24 of the 25- year lag. It implies a marginal benefit-cost ratio of 48.2, using a real discount rate of 5 percent per annum and a modified internal rate of return of 24% per annum. The benefit-cost ratio varied significantly across models with different lag structures or that omitted the trend or the private research variable, but across the same models the modified internal rate of return was very stable, ranging from 23% per annum to 27% per annum. These results suggest that the revitalized investment in research spending under INIA has been very profitable for Uruguay, and that a greater rate of investment would have been justified.

description: Since 2000, the California Department of Food and Agriculture (CDFA), has spent approximately $40 million per year to contain and control the Glassy Winged Sharpshooter (GWSS), which spreads Pierce’s Disease (PD). Compliance with the program has cost the nursery industry approximately $7 million per year in recent years. Using a simulation model of the market for California winegrapes, we estimate PD costs winegrape growers and consumers $61 million annually, with the current program in place. If the PD Control Program ended, and the GWSS was distributed freely throughout California, the annual cost to the winegrape industry would increase by $261 million.

description: Already in the first edition of this book (Barone and Paterno, "Fundamentals and Physics and Applications of the Josephson Effect", Wiley 1982), a great number of interesting and important applications for Josephson junctions were discussed. In the decades that have passed since then, several new applications have emerged. This chapter treats one such new class of applications: quantum optics and quantum information processing (QIP) based on superconducting circuits with Josephson junctions. In this chapter, we aim to explain the basics of superconducting quantum circuits with Josephson junctions and demonstrate how these systems open up new prospects, both for QIP and for the study of quantum optics and atomic physics.

Jurczak {\it et al}, Phys. Rev. Lett. {\bf 77}, 1727 (1996)), we study whether the Rayleigh resonance originates from the diffraction on a density grating, and is therefore a probe of transport of atoms in optical lattices. It turns out that this is not the case: the Rayleigh line is instead a measure of the cooling rate, while spatial diffusion contributes to the scattering spectrum with a much broader resonance.

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.

Coupling functions in climate

description: We examine how coupling functions in the theory of dynamical systems provide a quantitative window into climate dynamics. Previously we have shown that a one-dimensional periodic non-autonomous stochastic dynamical system can simulate the monthly statistics of surface air temperature data. Here we expand this approach to two-dimensional dynamical systems to include interactions between two sub-systems of the climate. The relevant coupling functions are constructed from the covariance of the data from the two sub-systems. We demonstrate the method on two tropical climate indices; The El-Niño--Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD), to interpret the mutual interactions between these two air-sea interaction phenomena in the Pacific and Indian Oceans. The coupling function reveals that ENSO mainly controls the seasonal variability of the IOD during its mature phase. This demonstrates the plausibility of constructing a network model for the seasonal variability of climate systems based on such coupling functions.

Axially symmetric Einstein-Straus models

description: The existence of static and axially symmetric regions in a Friedman-Lemaitre cosmology is investigated under the only assumption that the cosmic time and the static time match properly on the boundary hypersurface. It turns out that the most general form for the static region is a two-sphere with arbitrarily changing radius which moves along the axis of symmetry in a determined way. The geometry of the interior region is completely determined in terms of background objects. When any of the most widely used energy-momentum contents for the interior region is imposed, both the interior geometry and the shape of the static region must become exactly spherically symmetric. This shows that the Einstein-Straus model, which is the generally accepted answer for the null influence of the cosmic expansion on the local physics, is not a robust model and it is rather an exceptional and isolated situation. Hence, its suitability for solving the interplay between cosmic expansion and local physics is doubtful and more adequate models should be investigated.

Families of line-graphs and their quantization

description: Any directed graph G with N vertices and J edges has an associated line-graph L(G) where the J edges form the vertices of L(G). We show that the non-zero eigenvalues of the adjacency matrices are the same for all graphs of such a family L^n(G). We give necessary and sufficient conditions for a line-graph to be quantisable and demonstrate that the spectra of associated quantum propagators follow the predictions of random matrices under very general conditions. Line-graphs may therefore serve as models to study the semiclassical limit (of large matrix size) of a quantum dynamics on graphs with fixed classical behaviour.

Structural properties of the geometrically frustrated pyrochlore Tb2Ti2O7

description: Although materials that exhibit nearest-neighbor-only antiferromagnetic interactions and geometrical frustration theoretically should not magnetically order in the absence of disorder, few such systems have been observed experimentally. One such system appears to be the pyrochlore Tb2Ti2O7. However, previous structural studies indicated that Tb2Ti2O7 is an imperfect pyrochlore. To clarify the situation, we performed neutron powder diffraction (NPD) and x-ray absorption fine structure (XAFS) measurements on samples that were prepared identically to those that show no magnetic order. The NPD measurements show that the long-range structure of Tb2Ti2O7 is well ordered with no structural transitions between 4.5 and 600 K. In articular, mean-squared displacements (u^2's) for each site follow a Debye model with no offsets. No evidence for Tb/Ti site interchange was observed within an upper limit of 2%. Likewise, no excess or deficiency in the oxygen stoichiometry was observed, within an upper limit of 2% of the nominal pyrochlore value. Tb L3- and Ti K-edge XAFS measurements from 20-300 K similarly indicate a well-ordered local structure. Other aspects of the structure are considered. We conclude that Tb2Ti2O7 has, within experimental error, an ideal, disorder-free pyrochlore lattice, thereby allowing the system to remain in a dynamic, frustrated spin state to the lowest observed temperatures.

description: The former Soviet republic of Georgia is reputedly the cradle of wine and has enjoyed at least 8000 vintages. It has also been a major supplier of wine to Russia for at least 200 years, but to few other countries. In 2006, however, Russia imposed a ban on beverage imports from Georgia. Since then this relatively poor country, in which nearly half the population is rural and most farmers (average holding 1.2 ha) have a vineyard, has been seeking to develop new export markets for its wine. This paper assesses the potential for growth in Georgia’s wine production and exports. It then outlines ways to addresses the challenges involved in trying to realize that potential, drawing on the experience of other countries that have expanded their wine exports in the past two decades. Implications for policy are drawn out in the final section.

description: The transferred-electron oscillator (TEO) is a device used in microwave applications that utilizes the negative differential mobility (NDM) effect to generate continuous oscillations. Recently, NDM was observed in intrinsic single-crystalline chemical vapor deposition (SC-CVD) diamond. The occurrence was explained by the electron repopulation between its different conduction band valleys. This paper presents the results of constructing a diamond TEO based on the NDM effect. A series of experiments has been performed for varying voltages, temperatures and resonator parameters on three SC-CVD diamond samples of different thicknesses. For the temperature range 90-300 K, we observe transferred-electron oscillations in diamond.

description: How much has food abundance, attributable to U.S. public agricultural R&D, contributed to the high and rising U.S. obesity rates? In this paper we investigate the effects of public investment in agricultural R&D on food prices, per capita calorie consumption, adult body weight, obesity, public health-care expenditures related to obesity, and social welfare. First we use an econometric model to estimate the average effect of an incremental investment in agricultural R&D on the farm prices of ten categories of farm commodities. Next, we use the econometric results in a simulation model to estimate the implied changes in prices and quantities consumed of nine categories of food for given changes in research expenditures. Finally, we estimate the corresponding changes in social welfare, including both the traditional measures of changes in economic surplus in markets for food and farm commodities, and changes in public health-care expenditures associated with the predicted changes in food consumption and hence obesity. We find that a 10 percent increase in the stream of annual U.S. public investment in agricultural R&D in the latter half of the 20th century would have caused a modest increase in average daily calorie consumption of American adults, resulting in small increases in social costs of obesity. On the other hand, such an increase in spending would have generated very substantial net national benefits given the very large benefit-cost ratios for agricultural R&D.

description: Historically, the onset of green revolution that led to the introduction of high-yielding varieties (HYV) seeds rewrote the growth story of Indian agriculture. In the long term side effects of intensive farming were realized. In the meanwhile this success led to introduction of Bacillus Thuringiensis (Bt) cotton in India. Since then various divergent voices are being raised to protect traditional seed holding rights of the farmers. The policy paralysis due to elusive fear of patent rights has contributed to stalemate in embracing Genetically Modified (GM) crops. The study finds that the heightened scrutiny due to those fears brought new evidence about non-viability of such crops for Indian conditions. The agriculture sector has overcome the stalemate and is silently evolving to embrace its vast cultural knowledge and biodiversity along with non GM technology. The study is centered on the role of trade related aspects of intellectual property rights (TRIPS) and its impact on agricultural innovation lead by traditional knowledge and biotechnology. The data extracted from RBI, FAO and UNCOMTRADE WITS suggests that the share of primary products in the total exports is on decline. Similarly, the yield of Bt Cotton has become stagnant after an initial increase till 2004. After critically analyzing the reasons for current decline, the study suggests a relook at innovation by increasing the research and development (R&D) expenditure in traditional knowledge (TK) and biotechnology by both public and private stakeholders.
