description: Two overburden dump sites were selected for vegetation study out of which one site was reclaimed one year back
and other site 18 year back. Tree species were planted at these sites with mostly regular distribution. Herbaceous
vegetation development on these sites were analysed along with tree layer to find out their development in term of extent
of presence and distribution. The initial pattern of herb species distribution is contagious. In subsequent years of
development of vegetation, the herb species found to follow random distribution. Development of tree canopy and
increase in shade on ground floor may be one of the dominant factors for the herb species to develop random distribution
characteristics along the course of succession. The species richness is similar at both the sites which indicate
contribution by local surrounding gene pool of the natural ecosystem of Sukinda valley.

description: Tropical Horticulture Enterprises (T.H.E) is a Ugandan initiative that works to add value to fruits, bananas and vegetables. The main out put of this initiative are processed dried fruits, fresh fruits, banana flour and fresh vegetables. T.H.E taps the 22% of banana and fruit loss at farm gate due to failure to access markets timely, besides poor handling knowledge and poor storage facilities in rural agricultural producing areas in the country. The initiative boasts of linkage with farmers and it has a bottom up network through which farmers have benefited in various trainings. The main objective of this initiative is to improve farmer’s incomes through providing an alternative avenue and market access to foods produced and ferried to markets without any value addition. This initiative adds value by way of preservation through sun drying of fruits and bananas. It also vacuum packs fresh fruits and vegetables. The dried bananas are milled into flour which provides an additional food variety to maize flour and rice on the market for the above crops. It promotes employment opportunities in the country due to multipliers effect, boosts nutrition values and maintain food security in the country and the region at large.

description: For a cloud service provider, delivering optimal system performance while fulfilling Quality of Service (QoS) obligations is critical for maintaining a viably profitable business. This goal is often hard to attain given the irregular nature of cloud computing jobs. These jobs expect high QoS on an on-demand fashion, that is on random arrival. To optimize the response to such client demands, cloud service providers organize the cloud computing environment as a multi-tier architecture. Each tier executes its designated tasks and passes the job to the next tier; in a fashion similar, but not identical, to the traditional job-shop environments. An optimization process must take place to schedule the appropriate tasks of the job on the resources of the tier, so as to meet the QoS expectations of the job. Existing approaches employ scheduling strategies that consider the performance optimization at the individual resource level and produce optimal single-tier driven schedules. Due to the sequential nature of the multi-tier environment, the impact of such schedules on the performance of other resources and tiers tend to be ignored, resulting in a less than optimal performance when measured at the multi-tier level. In this paper, we propose a multi-tier-oriented job scheduling and allocation technique. The scheduling and allocation process is formulated as a problem of assigning jobs to the resource queues of the cloud computing environment, where each resource of the environment employs a queue to hold the jobs assigned to it. The scheduling problem is NP-hard, as such a biologically inspired genetic algorithm is proposed. The computing resources across all tiers of the environment are virtualized in one resource by means of a single queue virtualization. A chromosome that mimics the sequencing and allocation of the tasks in the proposed virtual queue is proposed.

description: The objective of this paper is to propose an alternative measure of irrigation water efficiency based on the concept of input- specific technical efficiency, which contracts with measures previously used in the literature. The proposed methodology is applied to a randomly selected sample of 144 citrus growing farms located in Nabeul (Tunisia). A stochastic production frontier approach, based on Battese and Coelli’s (1995) inefficiency effect model, is used to obtain farm-specific estimates of technical and irrigation water efficiency. In addition, a second-stage regression approach is used to identify the factors influencing irrigation water efficiency differentials across citrus growing farms. Results indicate that technical efficiency ranges from a minimum of 12.9% to a maximum of 90.7% with an average estimate of 67.7%. This suggests that citrus producers may increase their production by as much as 32.3% through more efficient use of production inputs. Further, mean irrigation water efficiency is found to be 53%, which is much lower than technical efficiency and also exhibits greater variability ranging from 1.6% to 98.87%. The estimated mean irrigation water efficiency implies that the observed quantity of marketable citrus could have been maintained by using the observed values of other inputs while using 47.0% less of irrigation water. Moreover, the estimated mean irrigation water technical cost efficiency is found to be 70.81% indicating a potential decrease of 29.19% in total cost by adjusting irrigation water to its efficient level. In addition, the vast majority of farms have achieved irrigation water technical cost efficiency greater than 90% (71% of farms). Finally, the analysis of the sources of efficiency differentials among farmers showed that farmer’s age, farm’s size, education level, agricultural training, the share of productive trees and the water disposable perception tend to affect positively the degree of both technical and irrigation water efficiency.

description: We study the effect on leptogenesis due to $B-L$ cosmic strings of a $U(1)_{B-L}$ extension of the Standard Model. The disappearance of closed loops of $B-L$ cosmic strings can produce heavy right handed neutrinos, $N_R$'s, whose CP-asymmetric decay in out-of-thermal equilibrium condition can give rise to a net lepton ($L$) asymmetry which is then converted, due to sphaleron transitions, to a Baryon ($B$) asymmetry. This is studied by using the relevant Boltzmann equations and including the effects of both thermal and string generated non-thermal $N_R$'s. We explore the parameter region spanned by the effective light neutrino mass parameter $\tilde{m}_1$, the mass $M_1$ of the lightest of the heavy right-handed neutrinos (or equivalently the Yukawa coupling $h_1$) and the scale of $B-L$ symmetry breaking, $η_{B-L}$, and show that there exist ranges of values of these parameters, in particular with $η_{B-L} > 10^{11}\gev$ and $h_1\gsim 0.01$, for which the cosmic string generated non-thermal $N_R$'s can give the dominant contribution to, and indeed produce, the observed Baryon Asymmetry of the Universe when the purely thermal leptogenesis mechanism is not sufficient. We also discuss how, depending on the values of $η_{B-L}$, $\tilde{m}_1$ and $h_1$, our results lead to upper bounds on $\sinδ$, where $δ$ is the the CP violating phase that determines the CP asymmetry in the decay of the heavy right handed neutrino responsible for generating the $L$-asymmetry.

description: Modeling user preferences (long-term history) and user dynamics (short-term history) is of greatest importance to build efficient sequential recommender systems. The challenge lies in the successful combination of the whole user's history and his recent actions (sequential dynamics) to provide personalized recommendations. Existing methods capture the sequential dynamics of a user using fixed-order Markov chains (usually first order chains) regardless of the user, which limits both the impact of the past of the user on the recommendation and the ability to adapt its length to the user profile. In this article, we propose to use frequent sequences to identify the most relevant part of the user history for the recommendation. The most salient items are then used in a unified metric model that embeds items based on user preferences and sequential dynamics. Extensive experiments demonstrate that our method outperforms state-of-the-art, especially on sparse datasets. We show that considering sequences of varying lengths improves the recommendations and we also emphasize that these sequences provide explanations on the recommendation.

description: Cloud computing environments often have to deal with random-arrival computational workloads that vary in resource requirements and demand high Quality of Service (QoS) obligations. It is typical that a Service-Level-Agreement (SLA) is employed to govern the QoS obligations of the cloud computing service provider to the client. A typical challenge service-providers face every day is maintaining a balance between the limited resources available for computing and the high QoS requirements of varying random demands. Any imbalance in managing these conflicting objectives may result in either dissatisfied clients and potentially significant commercial penalties, or an over-resourced cloud computing environment that can be significantly costly to acquire and operate. Thus, scheduling the clients' workloads as they arrive at the environment to ensure their timely execution has been a central issue in cloud computing. Various approaches have been reported in the literature to address this problem: Shortest-Queue, Join-Idle-Queue, Round Robin, MinMin, MaxMin, and Least Connection, to name a few. However, optimization strategies of such approaches fail to capture QoS obligations and their associated commercial penalties. This paper presents an approach for service-level driven load scheduling and balancing in multi-tier environments. Joint scheduling and balancing operations are employed to distribute and schedule jobs among the resources, such that the total waiting time of client jobs is minimized, and thus the potential of a penalty to be incurred by the service provider is mitigated. A penalty model is used to quantify the penalty the service provider incurs as a function of the jobs' total waiting time. A Virtual-Queue abstraction is proposed to facilitate optimal job scheduling at the tier level. This problem is NP-complete, a genetic algorithm is proposed for computing job schedules.

description: The long-term reduction of hunger and poverty in Sub-Saharan Africa remains one of the great challenges for the International development community. Poverty in Africa is predominately rural, majority of the poor people live in rural areas and are dependent on food production through farming or livestock keeping for most of their livelihood. It is estimated that over two hundred million people in Sub-Saharan Africa live in extreme poverty and among these are the rural poor in Eastern and Southern Africa where the worlds highest concentration of poor people are found. Given Agriculture’s central role in the region’s economies, can agriculture play a major role in poverty alleviation? How can Africa’s role in poverty reduction be enhanced? What could be done to boost agricultural production, economic growth and the incomes of the rural poor to help achieve the Millennium Development Goals especially that of cutting poverty in half by 2015. These are some of the questions the author addresses in the paper - A roadmap that is considered extremely useful and timely.

description: We present genetIC, a new code for generating initial conditions for cosmological N-body simulations. The code allows precise, user-specified alterations to be made to arbitrary regions of the simulation (while maintaining consistency with the statistical ensemble). These "genetic modifications" allow, for example, the history, mass, or environment of a target halo to be altered in order to study the effect on their evolution. The code natively supports initial conditions with nested zoom regions at progressively increasing resolution. Modifications in the high-resolution region must propagate self-consistently onto the lower resolution grids; to enable this while maintaining a small memory footprint, we introduce a Fourier-space filtering approach to generating fields at variable resolution. Due to a close correspondence with modifications, constrained initial conditions can also be produced by genetIC (for example with the aim of matching structures in the local Universe). We test the accuracy of modifications performed within zoom initial conditions. The code achieves sub-percent precision, which is easily sufficient for current applications in galaxy formation.

description: The study was used by Plan International to formulate a common Nutrition Action Plan for its food and nutrition security interventions in developing countries. The aim was to get insight into the food and nutrition security as well as livelihoods status at the household and community level of the people of Sissala. Specifically the study focused on the contribution made by Plan interventions to improve livelihoods, the food and nutrition security of households and communities, the impact on gender and to identify indicators for monitoring and evaluation. The survey was carried out in three centrally placed communities selected to ensure an even coverage of Plan Ghana activities in the Sissala West District of Ghana. Data was collected at community and individual levels using Participatory Rapid Appraisal (PRA) procedures consisting of focus group discussions, seasonal calendars, preference ranking, and matrix scoring and ranking together with limited questionnaire administration, observation and photography. Results indicated the provision of health, education, economic, social and environmental conservation activities in the form of microfinance, awareness creation, collective services and structural placements. Found to be broad based, the services relate to and benefit women, men, the youth and children at household and community levels. The study revealed the need for the intensification of efforts, additional strategies and programmes, a wider area of coverage and recruitment of more hands to overcome the acute deprivations in Sissala
A conservative prior for bayesian hierarchical models in biostatistics
Creators: name: Hossain, Md. Shahadut
Publisher: name: University of British Columbia
Year: 2009

description: Hierarchical models are suitable and very natural to model many real life phenomena, where data arise in nested fashion. The use of Bayesian approach to hierarchical models has numerous advantages over the classical approach. Estimating a phenomenon with hierarchical model can be viewed as a smoothing problem, and hence while summarizing such a phenomenon via hierarchical model we do not want to undersmooth the phenomenon. That is, in most of the practical applications undersmoothing is more serious type of error than oversmoothing. So, we need an estimation approach which can guard against undersmoothing. If we can control the undersmoothing reasonably, we may get a better calibrated summary of the phenomenon we estimate. In this study, we have incorporated the aspect of smoothing in estimating the parameters of Bayesian hierarchical models. In doing so we have proposed a conservative prior for the variance component to achieve the adequate degree of smoothness while estimating the phenomenon under study. We have conducted simulation studies to decide about the appropriate values to be used for the hyperparameter while using the conservative prior to ensure the adequate degree of smoothness. We have investigated the performance of the proposed conservative prior in guarding against undersmoothing in simple normal-normal hierarchical models (random effects models for normal response) and in non-parametric regression curve estimation problem via simulation studies. We have also investigated the performance of the proposed prior compared to those of the uniform shrinkage prior and the Jeffreys' prior, with respect to both guarding against undersmoothing and the MSE of the estimated model parameters, through simulation studies.

The magnetization reversal occurs in avalanches of spin flips, which are pinned by the topological constraints of the underlying graph. The hysteresis loop and avalanche sizes are analyzed and classified in terms of graph's connectivity and clustering. The results are relevant for magnets with a hierarchical spatial inhomogeneity and for design of nanoscale magnetic devices.

description: This study examines the factors that determine the export performance of three major agricultural exportable commodities of cocoa, rubber and palm-kernel in the context of liberalization. Using time series data covering thirty three years and to avoid spurious result, error correction model was applied in the analysis. The unit root test is in line with the a priori expectation that macroeconomic variables are not stationary at their level. Virtually all the variables tested were differenced once before attaining stationarity. Each of the three equations indicated that the dependent variables cointegrated with their arguments at 1 percent level. There is the existence of short term and long term equilibrium relationships between the dependent variables and their determinants. The results of the parsimonious error correction specifications showed that the previous year’s output and the net value of world trade negatively affect cocoa exports at 1 percent level while the previous year’s GDP positively contributes to cocoa exports at 5 percent. The lagged price ratio reduces rubber exports significantly at 5 percent but the real exchange rate significantly increases the export performance of rubber at 10 percent level. The previous year’s exports of palm kernel and the real GDP contributed positively to palm-kernel exports at 5 percent level while the lagged premium and palm kernel output negatively contributed to its export at 5 percent and 10 percent respectively. Promotion of agricultural exports is essential to reduce the burden of dependence on oil exports

description: Demonstrating the importance of the circumstantial writings by Paul Valéry, the present essay points out his very first “commission” on Leonardo da Vinci as emblematic of a new sensitive philosophical reflexiveness. In fact, Valéry kept returning to the great renaissance phenomenon of Leonardo, in his twisted Introduction à la Méthode de Léonard de Vinci (1894), rewritten some 25 years later with Note et digression (1919), as well in his staging of philosophers and artists in Léonard et les philosophes (1929). The dislocations taking place within these texts outline an emphasis on the sensible, which remained almost hidden in Valéry’s well-known promotion of the spirit in art.

description: The rules of local superfield Lagrangian quantization in reducible non-Abelian hypergauge functions are formulated for an arbitrary gauge theory. The generating functionals of standard and vertex Green's functions which depend on the Grassmann variable $η$ via super(anti)fields and sources are constructed. The difference between the local quantum and the gauge fixing actions determines an almost Hamiltonian system such that translations with respect to $η$ along the solutions of this system define the superfield BRST transformations. The Ward identities are derived and the gauge independence of the S-matrix is proved.

Image-based flow decomposition using empirical wavelet transform

Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We propose an image-based flow decomposition developed from the two-dimensional (2D) tensor empirical wavelet transform (EWT) (Gilles 2013). The idea is to decompose the instantaneous flow data, or its visualisation, adaptively according to the averaged Fourier supports for the identification of spatially localised structures. The resulting EWT modes stand for the decomposed flows, and each accounts for part of the spectrum, illustrating fluid physics with different scales superimposed in the original flow. With the proposed method, decomposition of an instantaneous 3D flow becomes feasible without resorting to its time series. Examples first focus on the interaction between a jet plume and 2D wake, where only experimental visualisations are available. The proposed method is capable of separating the jet/wake flows and their instabilities. Then the decomposition is applied to an early stage boundary layer transition, where direct numerical simulations provided a full data-set. The tested inputs are the 3D flow data and its visualisation using streamwise velocity & λ2 vortex identification criterion. With both types of inputs, EWT modes robustly extract the streamwise-elongated streaks, multiple secondary instabilities and helical vortex filaments. Results from bi-global stability analysis justify the EWT modes that represent the streak instabilities. In contrast to Proper Orthogonal Decomposition or Dynamic Modal Decomposition that extract spatial modes according to energy or frequency, EWT provides a new strategy as to decompose an instantaneous flow from its spatial scales.

description: When using Bayesian inference, one needs to choose a prior distribution for parameters. The well-known Jeffreys prior is based on the Riemann metric tensor on a statistical manifold. Takeuchi and Amari defined the $α$-parallel prior,, which generalized the Jeffreys prior by exploiting higher-order geometric object, known as Chentsov-Amari tensor. In this paper, we propose a new prior based on the Weyl structure on a statistical manifold. It turns out that our prior is a special case of the $α$-parallel prior with the parameter $α$ equals $-n$, where $n$ is the dimension of the underlying statistical manifold and the minus sign is a result of conventions used in the definition of $α$-connections. This makes the choice for the parameter $α$ more canonical. We calculated the Weyl prior for univariate Gaussian and multivariate Gaussian distribution. The Weyl prior of the univariate Gaussian turns out to be the uniform prior.

description: The objective of this study is to evaluate pesticide use as an important factor affecting potential adoption and farm level impact of genetically modified (GM) vegetable varieties in Ghana. Tomato is the most consumed vegetable and a food security crop. Cabbage is a vegetable of growing importance but limited cultivation and is produced in urban areas. Garden egg is a native African crop of wide consumption and importance for rural economies. Farm level information was collected in randomly selected sites in southern and central regions of Ghana. Partial budget analysis shows that investments in pesticides are rather low, especially for tomato and garden egg. Analysis of production using an abatement framework shows that insecticide amounts are significant in determining cabbage output levels only. Rate of returns of GM seeds however can still be high. GM varieties would need to show not only a high abatement rate and a high yield potential but mainly an affordable price, to reduce total costs and induce adoption.

description: The time analysis of the signal induced by the drift of charge carriers in high purity germanium detectors provides information on the event topology. Millions of charge carriers are produced in a typical event. Their initial distribution, stochastic diffusion and Coulomb self-repulsion affect the time structure of the signal. We present a comprehensive study of these effects and evaluate their impact on the event discrimination capabilities for the three geometries which will be used in the Legend experiment for neutrinoless double-beta decay.

description: In recent years, employees have been encouraged to engage in innovative behaviors within the framework of the concept of servant leadership based on ethical values in private enterprises and public institutions in different cultures. In this study, the relationship between servant leadership and innovative behavior is examined with 415 data obtained by convenience sampling method in banks operating in Adana province. Correlation and regression analyses show that there is a positive relationship between servant leadership and innovative behavior, and servant leadership significantly affects innovative behavior.
Valéry: une poetique du sensible

description: Contrary to the prevailing view, there is not one, but at least two poetic theories in Paul Valéry: the intellectual, formalist and technical poetics Valéry is usually associated to conflicts with another poetics, which highlights sensitivity, lyricism and subjectivity. The constitutive duplicity of Valéry’s literary theory has probably something to do with the ambiguity of his relationship with Stéphane Mallarmé.

description: We use direct numerical simulation to study the temporal evolution of a perturbation localized on the turbulent layer that typically separates a cloud from the surrounding clear air. Across this shearless layer, a turbulent kinetic energy gradient naturally forms. Here, a finite perturbation in the form of a local initial temperature fluctuation is applied to simulate a hydrodynamic instability inside the background turbulent air flow. A numerical initial value problem for two diametrically opposite types of drop population distributions is then solved. Specifically, we consider a mono-disperse population of droplets of 15 $μ$m of radius and a poly-disperse distribution with radii in the range 0.6 - 30 $μ$m. For both distributions, it is observed that the evaporation and condensation have a dramatically different weight inside the homogeneous cloudy region and the interfacial anisotropic mixing region. It is observed that the dynamics of drop collisions is highly effected by the turbulence structure of the host region. The two populations show a common aspect during their energy decay transient. That is the increased probability of collisions in the interfacial layer hat houses intense anisotropic velocity fluctuations. This layer, in fact, induces an enhanced differentiation on droplets kinetic energy and sizes. Both polydisperse and monodisperse initial particle distributions contain $10^7$ droplets, matching an initial liquid water content of $0.8 g/m^3$. An estimate of the turbulent collision kernel for geometric collisions used in the population balance equations is given. A preliminary discussion is presented on the structure of the two unsteady non ergodic collision kernels obtained inside the cloud interface region.

Land Reform and Farm-Household Income Inequality: The Case of Georgia

description: The income inequality implications of land reform are examined for the case of Georgia using regression-based inequality decomposition techniques. An egalitarian land redistribution is likely to equalize per-capita income among farm households, implying that continuing the land reform process in Georgia is likely to benefit poorer households, relatively speaking. However, land fragmentation was found to be disequalizing, and therefore land market developments that enable plot consolidation are not less important for inequality than the land redistribution itself. Both landholdings and farm assets have favorable inequality implications not only through farm income but also through non-farm income, implying that these productive assets increase the economic opportunities of rural households in the non-farm sector as well, perhaps by easing borrowing constraints.
