description: Poverty is one of the Nigeria’s policy challenges stalling all efforts to develop rural areas and transform agriculture. Although, poverty is an endemic problem in Nigeria, available evidence shows that rural areas in the country are the most affected. This study advocates off-farm employment for poverty reduction in the rural areas. An empirical investigation was carried out among farming households in Kwara State, Nigeria to analyze the potentials of off-farm employment in poverty reduction. Kwara state is among the six poorest states in Nigeria. A four-stage sampling technique was employed to select 200 farming households used as sample for the study. Three analytical tools including: descriptive statistics, regression analysis, and Foster, Greer and Thorbecke (FGT) classes of poverty measures were used for data analysis. The result of the study shows that a typical household comprised more than 10 persons with a male household head. The average age of the household heads was 45.5 years. 73.3% practiced farming with off-farm work. Poverty analysis was disaggregated into age, marital status, household size and primary occupation. Poverty incidence and severity are more among households with farming as the sole occupation. Households combining off-farm jobs with farming are non-poor. Age, literacy level, household size and occupation were the determinants of off-farm employment of the farming households. Policy options which will increase rural productivity, reduce rural poverty and encourage youth participation in rural economy were suggested.

description: What is the shape of space in a spacetime? One way of addressing this issue is to consider edgeless spacelike submanifolds of the spacetime. An alternative is to foliate the spacetime by timelike curves and consider the quotient obtained by identifying points on the same timelike curve. In this article we investigate each of these notions and obtain conditions such that it yields a meaningful shape of space. We also consider the relationship between these two notions and find conditions for the quotient space to be diffeomorphic to any edgeless spacelike hypersurface. In particular, we find conditions in which merely local behavior (being spacelike) combined with the correct behavior on the homotopy level guarantees that a putative shape of space really is precisely that.

description: This research work follows the recent trend in most African countries in introducing (or strengthening) price support programs for selected cereals. Under this background, this study examines the impact of a potential implementation of a minimum support price MSP) policy on cereals in Ethiopia. To that end, positive and negative productivity shocks were considered under alternative producer and consumer pricing policies backed-up by public storage services. The quantitative analysis show that the effectiveness of price policies and government intervention in the commodity market depends on the nature of the productivity changes. Producer price floors are effective only when there are productivity gains which would ultimately decrease producer prices, suggesting the productivity enhancing role of this policy option. Also, producer price support works against consumers as prices of target commodities could not fall anymore beyond the level dictated by the support program. On the other hand, price ceiling on commodities is effective only when there are productivity losses since consumer prices tend to increase. Consumer price support policies help urban households since they slightly dampen increases in consumer prices and declines in incomes to these households. However, rural households lose more welfare mainly due to further losses in incomes as the control in consumer prices limit the increase in producer prices for cereals. The price policy of keeping producers prices of cereals within a 5% floor does not effectively affect the economy since producer prices tend to increase significantly if productivity is falling by the simulated levels due to exogenous shocks, such as extreme weather conditions.

description: The objective of this study is to evaluate the effect of Farmer Field Schools (FFSs) on cocoa yield in the Centre and South-west regions in Cameroon. The evaluation of FFSs is important for improving cocoa production by agricultural research and extension. This evaluation is done by using the “Propensity Score Matching” technique and Rosenbaum bounds sensitivity analysis method to ensure robustness of results. The data comes from IITA surveys conducted in 2009 and concerned 201 cocoa farmers in the Centre and South -West Regions in Cameroon for the 2008/2009 cocoa season. The sample cocoa farmers contain participants and non participants to FFSs. Results show that participate to FFSs have a positive and significant effect on the cocoa yield per hectare. This effect is estimated at about 97 kilograms per hectare. This effect is statistically significant at 10%, only for the kernel matching but not for the five nearest neighbors matching. This weak significant of FFS impact could be lead to the fact that farmers who joined FFS are those who have low capacity in cocoa production compare with those who did not joined FFS. This can also lead to the poor quality of FFSs training. The first recommendation is to promote the FFSs in the area where there is no FFSs by highlighting agricultural extension service. The second recommendation is to improve the quality of training in Farmer Fields Schools in other to increase their impacts on cocoa yield. In the current context of agricultural intensification challenges in developing countries, this analytical framework is of interest for policy makers for identifying conditions of farmer participation to FFSs and designing effective motivation strategies.

description: We present an overview of the LOFAR Tied-Array All-Sky Survey (LOTAAS) for radio pulsars and fast transients. The survey uses the high-band antennas of the LOFAR Superterp, the dense inner part of the LOFAR core, to survey the northern sky (dec > 0 deg) at a central observing frequency of 135 MHz. A total of 219 tied-array beams (coherent summation of station signals, covering 12 square degrees), as well as three incoherent beams (covering 67 square degrees) are formed in each survey pointing. For each ofthe 222 beams, total intensity is recorded at 491.52 us time resolution. Each observation integrates for 1 hr and covers 2592 channels from 119 to 151 MHz. This instrumental setup allows LOTAAS to reach a detection threshold of 1 to 5 mJy for periodic emission. Thus far, the LOTAAS survey has resulted in the discovery of 73 radio pulsars. Among these are two mildly recycled binary millisecond pulsars (P = 13 and 33 ms), as well as the slowest-spinning radio pulsar currently known (P = 23.5 s). The survey has thus far detected 311 known pulsars, with spin periods ranging from 4 ms to 5.0 s and dispersion measures from 3.0 to 217 pc/cc. Known pulsars are detected at flux densities consistent with literature values. We find that the LOTAAS pulsar discoveries have, on average, longer spin periods than the known pulsar population. This may reflect different selection biases between LOTAAS and previous surveys, though it is also possible that slower-spinning pulsars preferentially have steeper radio spectra. LOTAAS is the deepest all-sky pulsar survey using a digital aperture array; we discuss some of the lessons learned that can inform the approach for similar surveys using future radio telescopes such as the Square Kilometre Array.

description: Sewage discharges from Combined Sewer Overflow (CSO) structures into receiving waters can prevent floods in urban areas but can also harm ecosystems and public health. In many countries there is a lack of reliable data on their operational frequency and pollution loads released. Assessing the impact of CSOs is challenging, emission-based rules that focus on the number of spills per year are insufficient to quantify environmental harm and lack of continuous information on the receiving water makes impact-based regulations hard to enforce. In this Policy in Brief we present the current status and some policy recomendations to address CSO spills.

description: The sensitivity achievable by a pair of VIRGO detectors to stochastic and isotropic gravitational wave backgrounds produced in pre-big-bang models is discussed in view of the development of a second VIRGO interferometer. We describe a semi-analytical technique allowing to compute the signal-to-noise ratio for (monotonic or non-monotonic) logarithmic energy spectra of relic gravitons of arbitrary slope. We apply our results to the case of two correlated and coaligned VIRGO detectors and we compute their achievable sensitivities. We perform our calculations both for the usual case of minimal string cosmological scenario and in the case of a non-minimal scenario where a long dilaton dominated phase is present prior to the onset of the ordinary radiation dominated phase. In this framework, we investigate possible improvements of the achievable sensitivities by selective reduction of the thermal contributions (pendulum and pendulum's internal modes) to the noise power spectra of the detectors. Since a reduction of the shot noise does not increase significantly the expected sensitivity of a VIRGO pair (in spite of the relative spatial location of the two detectors) our findings support the experimental efforts directed towards a substantial reduction of thermal noise.

description: This paper investigates the extent to which crop diversification affects farm productivity and production risk in the Niger basin of Benin. The paper relies on a moment-based approach, and estimates a stochastic production function which captures the effects of crop diversification on the mean, the variance, and the skewness by controlling for the unobservable heterogeneities related to institutional factors and village specific conditions. The findings reveal that diversification across crops affects positively the mean, the variance, and the skewness, with the effects being statistically significant only in the case of the mean. Thus, diversification is important in reducing the exposure to downside risk.

description: Schwinger-Dyson equations for propagators are solved for the scalar $Φ^3$ theory and massive Wick-Cutkosky model. With the help of integral representation the results are obtained directly in Minkowski space in and beyond bare vertex approximation. Various renormalization scheme are employed which differ by the finite strength field renormalization function $Z$ . The $S-$matrix is puzzled from the Green's function and the effect of truncation of the DSEs is studied. Independently on the approximation the numerical solution breaks down for certain critical value of the coupling constant, for which the on-shell renormalized propagator starts to develop the unphysical singularity at very high space-like square of momenta.

description: We theoretically investigate the scattering process of Bogoliubov excitations on a rotating photon-fluid. Using the language of Noether currents we demonstrate the occurrence of a resonant amplification phenomenon, which reduces to the standard superradiance in the hydrodynamic limit. We make use of a time-domain formulation where superradiance emerges as a transient effect encoded in the amplitudes and phases of propagating localised wavepackets. Our findings generalize previous studies in quantum fluids to the case of a non-negligible quantum pressure and can be readily applied also to other physical systems, in particular atomic Bose-Einstein condensates. Finally we discuss ongoing experiments to observe superradiance in photon fluids, and how our time domain analysis can be used to characterise superradiant scattering in non-ideal experimental conditions.

description: Non-uniform blur, mainly caused by camera shake and motions of multiple objects, is one of the most common causes of image quality degradation. However, the traditional blind deblurring methods based on blur kernel estimation do not perform well on complicated non-uniform motion blurs. Recent studies show that GAN-based approaches achieve impressive performance on deblurring tasks. In this letter, to further improve the performance of GAN-based methods on deblurring tasks, we propose an edge heuristic multi-scale generative adversarial network(GAN), which uses the "coarse-to-fine" scheme to restore clear images in an end-to-end manner. In particular, an edge-enhanced network is designed to generate sharp edges as auxiliary information to guide the deblurring process. Furthermore, We propose a hierarchical content loss function for deblurring tasks. Extensive experiments on different datasets show that our method achieves state-of-the-art performance in dynamic scene deblurring.

description: We have performed an all-electron fully relativistic density functional calculation to study the magnetic properties of FeBr2. We show for the first time that the correlation effect enhances the contribution from orbital degrees of freedom of $d$ electrons to the total magnetic moment on Fe$^{2+}$ as opposed to common notion of nearly total quenching of the orbital moment on Fe$^{2+}$ site. The insulating nature of the system is correctly predicted when the Hubbard parameter U is included. Energy bands around the gap are very narrow in width and originate from the localized Fe-3$d$ orbitals, which indicates that FeBr2 is a typical example of the Mott insulator.

description: The diamond and zinc-blende semiconductors are well-known and have been widely studied for decades. Yet, their electronic structure still surprises with unexpected topological properties of the valence bands. In this joint theoretical and experimental investigation we demonstrate for the benchmark compounds InSb and GaAs that the electronic structure features topological surface states below the Fermi energy. Our parity analysis shows that the spin-orbit split-off band near the valence band maximum exhibits a strong topologically non-trivial behavior characterized by the $\mathcal{Z}_2$ invariants $(1;000)$. The non-trivial character emerges instantaneously with non-zero spin-orbit coupling, in contrast to the conventional topological phase transition mechanism. \textit{Ab initio}-based tight-binding calculations resolve topological surface states in the occupied electronic structure of InSb and GaAs, further confirmed experimentally by soft X-ray angle-resolved photoemission from both materials. Our findings are valid for all other materials whose valence bands are adiabatically linked to those of InSb, i.e., many diamond and zinc-blende semiconductors, as well as other related materials, such as half-Heusler compounds.

description: We present a detailed description of techniques developed to combine 3D numerical simulations and, subsequently, a single black hole close-limit approximation. This method has made it possible to compute the first complete waveforms covering the post-orbital dynamics of a binary black hole system with the numerical simulation covering the essential non-linear interaction before the close limit becomes applicable for the late time dynamics. To determine when close-limit perturbation theory is applicable we apply a combination of invariant a priori estimates and a posteriori consistency checks of the robustness of our results against exchange of linear and non-linear treatments near the interface. Once the numerically modeled binary system reaches a regime that can be treated as perturbations of the Kerr spacetime, we must approximately relate the numerical coordinates to the perturbative background coordinates. We also perform a rotation of a numerically defined tetrad to asymptotically reproduce the tetrad required in the perturbative treatment. We can then produce numerical Cauchy data for the close-limit evolution in the form of the Weyl scalar $ψ_4$ and its time derivative $\partial_tψ_4$ with both objects being first order coordinate and tetrad invariant. The Teukolsky equation in Boyer-Lindquist coordinates is adopted to further continue the evolution. To illustrate the application of these techniques we evolve a single Kerr hole and compute the spurious radiation as a measure of the error of the whole procedure. We also briefly discuss the extension of the project to make use of improved full numerical evolutions and outline the approach to a full understanding of astrophysical black hole binary systems which we can now pursue.

description: The Hamiltonian formulation of the teleparallel equivalent of general relativity is considered. Definitions of energy, momentum and angular momentum of the gravitational field arise from the integral form of the constraint equations of the theory. In particular, the gravitational energy-momentum is given by the integral of scalar densities over a three-dimensional spacelike hypersurface. The definition for the gravitational energy is investigated in the context of the Kerr black hole. In the evaluation of the energy contained within the external event horizon of the Kerr black hole we obtain a value strikingly close to the irreducible mass of the latter. The gravitational angular momentum is evaluated for the gravitational field of a thin, slowly rotating mass shell.

Quintessence as a run-away dilaton

description: We consider a late-time cosmological model based on a recent proposal that the infinite-bare-coupling limit of superstring/M-theory exists and has good phenomenological properties, including a vanishing cosmological constant, and a massless, decoupled dilaton. As it runs away to $+ \infty$, the dilaton can play the role of the quintessence field recently advocated to drive the late-time accelerated expansion of the Universe. If, as suggested by some string theory examples, appreciable deviations from General Relativity persist even today in the dark matter sector, the Universe may smoothly evolve from an initial "focusing" stage, lasting untill radiation--matter equality, to a "dragging" regime, which eventually gives rise to an accelerated expansion with frozen $Ω(\rm{dark energy})/Ω(\rm{dark matter})$.

description: Sample-selection issues are common problems in empirical studies of labor economics and other applied microeconomics. A common estimation method is maximum likelihood estimation under the assumption of joint normality. It is well known, however, that the violation of distributional assumptions leads to inconsistency of a maximum likelihood estimator. Early work on sample-selection models that relaxes the normality assumption was done by Lee (1983, 1984). His approach was to transform nonnormal disturbances in the models into normal variates that are then assumed to be jointly normally distributed. As we will see, this is a special case of the copula approach that Smith (2003) applies to sample-selection models. The copula approach adds more flexibility to model specifications. In this article, I discuss the maximum likelihood estimation of sample-selection models with the copula approach to relax the assumption of joint normality. Although there are several types of sample-selection models, I discuss two in particular: a bivariate sample-selection model and an endogenous switching regression model. I also introduce the Stata commands heckmancopula and switchcopula, which implement the estimation of each model, respectively.

 DISTRIBUTION: I have examined specimens of Coendou vestitus from only two definitely identifiable localities, both of which are in the western foothills of the eastern Andean cordillera in the Colombian department of Cundinamarca. However, Alberico et al. (1999) report a specimen from Villavicencio, on the eastern side of the Andes in the department of Meta.
 REMARKS: This species may be closely related to Coendou ichillus, C. pruinosus, and C. roosmalenorum, all of which also have bristle-quills in addition to ordinary defensive quills and soft fur in their dorsal pelage (Voss and da Silva, 2001). Diagnostic comparisons with those species were provided by Voss and da Silva (2001), whose text should also be consulted for a detailed description of the skin and skull of C. vestitus.

description: We explore memory effects associated to both Abelian and non-Abelian radiation getting to null infinity, in arbitrary even spacetime dimensions. Together with classical memories, linear and non-linear, amounting to permanent kicks in the velocity of the probes, we also discuss the higher-dimensional counterparts of quantum memory effects, manifesting themselves in modifications of the relative phases describing a configuration of several probes. In addition, we analyse the structure of the asymptotic symmetries of Maxwell's theory in any dimension, both even and odd, in the Lorenz gauge.

description: In this article, we describe a new individual patient data meta-analysis postestimation command, ipdforest. The command produces a forest plot following a one-stage meta-analysis with xtmixed or xtmelogit. (These commands have been renamed in Stata 13 to mixed and meqrlogit, respectively; ipdforest is currently not compatible with the new names.) The overall effect is obtained from the preceding mixed-effects regression and the study effects from linear or logistic regressions on each study, which are executed within ipdforest.
QCD Evolution of Transversity in Leading and Next-to-Leading Order

description: I shall present a rather pedagogical discussion of the transversity distributions in the quark-parton model and, in particular, the role of perturbative QCD corrections. Among the topics I shall discuss are: LO and NLO evolution, the Soffer bound and so-called K factors in the Drell-Yan process. The main conclusion will be that, compared to unpolarised or even longitudinally polarised hadron scattering, the case of transverse spin should actually provide a far clearer window onto the workings of QCD and the interplay with the quark-parton model.

description: In this article, we consider two recently proposed semiparametric estimators for distribution-free binary response models under a conditional median restriction. We show that these estimators can be implemented in Stata by using the nl command through simple modifications to the nonlinear least-squares probit criterion function. We then introduce dfbr, a new Stata command that implements these estimators, and provide several examples of its usage. Although it is straightforward to carry out the estimation with nl, the dfbr implementation uses Mata for improved performance and robustness.

description: Pesticides contamination is a global environmental and public health concern due to their carcinogenic and highly toxic nature for all kind of living organisms including plants, animals and humans. Pakistan as an agriculture-based country, annually use a huge amount of organochlorine pesticides (OC) to control insect pests and different diseases of crops, resulting in environmental contaminations and their subsequent exposure to humans. Unfortunately, more than half million people are endured annually from OC pesticides and other agro-chemicals poisoning in Pakistan. However, recent data on the uses, contamination and exposure of pesticides in Pakistan are largely unavailable. This review summarizes the recent information and provides data on consumption and contamination of pesticides with a particular focus on their exposure to humans in Pakistan. Studies must be conducted to precisely determine the current use, contamination level and exposure of pesticides in Pakistan.
