description: One of the means by which farm level productivity can be increased is through the introduction and dissemination of improved agricultural technologies to farmers. This is possible if and only if, information on the adoption and risk taking behaviour of farmers is known in advance. While some studies have attempted to assess the factors behind the adoption behaviour of farmers, they have either been limited in scope or they focused on few selected locations and/or commodities. The objective of this study is to identify the factors, which exert significant influence on the adoption behaviour of farmers and the intensity of adoption from a nation survey. A total of 1920 farm household heads drawn from four National Regional States were included in the survey. The result shows that younger farmers, famers with larger land size, farmer living closer to market, and farmers who had closer contact with the extension system are more likely to adopt new technology and use it more. The result underscores the need for research and extension programs to be sensitive to the needs of farmers when developing and disseminating technologies that are relevant to their agro‐ecologies

description: We consider a version of Palais' Principle of Symmetric Criticality (PSC) that is applicable to the Lie symmetry reduction of Lagrangian field theories. PSC asserts that, given a group action, for any group-invariant Lagrangian the equations obtained by restriction of Euler-Lagrange equations to group-invariant fields are equivalent to the Euler-Lagrange equations of a canonically defined, symmetry-reduced Lagrangian. We investigate the validity of PSC for local gravitational theories built from a metric. It is shown that there are two independent conditions which must be satisfied for PSC to be valid. One of these conditions, obtained previously in the context of transverse symmetry group actions, provides a generalization of the well-known unimodularity condition that arises in spatially homogeneous cosmological models. The other condition seems to be new. The conditions that determine the validity of PSC are equivalent to pointwise conditions on the group action alone. These results are illustrated with a variety of examples from general relativity. It is straightforward to generalize all of our results to any relativistic field theory.

description: ‘Interactions’ between and among moving objects occur across widely varying spatial and temporal scales and are an important component for understanding spatial behaviours such as mating, predation, and territoriality as well as phenomena resulting from these behaviours such as disease spread. ‘Dynamic interactions’ refer to interactions that are defined based on proximity in both space and time and while social network analysis can be applicable for studying interactions among human individuals as well as among animal individuals, a ‘dyad’ (comprised of two individuals) is more often used as the unit for studying interactions between animal individuals. The two main approaches of quantifying dynamic interactions between two individuals involve treating the locations as discrete points or examining the paths that are inferred as trajectories between subsequent points. In this research I present results that use a hybrid approach of quantifying interactions using spatiotemporal point proximity and comparing movement path parameters to infer interaction behaviors. This new method is applied to thirteen black-backed jackal dyads in Etosha National Park, Namibia.

description: Increases in foreign transfers and capital inflows helped spur Ethiopia’s economic growth in recent years, but also contributed to a real exchange rate appreciation that reduced incentives for production of tradable goods. Then, beginning in March 2008, following major external shocks, foreign exchange for imports was restricted to avoid excessive drawdown of reserves. This paper examines the implications of these shocks and policies using a Computable General Equilibrium (CGE) model of the Ethiopian economy. The results show that there are substantial costs to both foreign exchange rationing and real exchange rate appreciation in terms of economic efficiency and income distribution.

description: In this paper we investigate in the large-$N_c$ limit ($N_c$ is the number of colored quarks) the phase structure of a massless (1+1)-dimensional quark model with four-quark interaction and in the presence of baryon ($μ_B$), isospin ($μ_I$) and chiral isospin ($μ_{I5}$) chemical potentials as well as at nonzero temperature. It is established that chiral isospin chemical potential leads to the generation of charged pion condensation (PC) in dense (nonzero baryon density) and chiral asymmetric quark matter for a wide range of isospin densities. It is shown that there exists a duality correspondence between the chiral symmetry breaking and the charged PC phenomena at any values of temperature even for very hot quark gluon plasma. Moreover, it is shown that charged PC phase with nonzero baryon density can be induced in the model at comparatively high temperatures. This opens up new possible physical systems, where it can be of importance, such as heavy ion collisions, just born neutron stars (proto-neutron stars), supernovas as well as neutron star mergers.

description: We have studied the collective phenomena of multicomponent glasses at ultra low temperatures [Strehlow, et. al, Phys. Rev. Lett 80, 5361 (1998)] by taking into account the proper interaction between tunneling centers. We have considered both double and triple well potentials with different types of interactions. We show that a phase with coherent motion appears for a range of parameters when the path of tunneling is coursed by an interaction of the XY type, while the usual Ising like interaction does not lead to the expected collective phenomena. In the phase of coherent motion, the dipole moment and the low-energy levels oscillate with a frequency proportional to the number of tunneling centers in the system. Simultaneous level crossing occurs between the ground and first excited states. The effects of long-range interactions and also of random couplings have been also studied for a one- and two-dimensional array of tunneling centers. We find that long-range interactions do not affect the coherent motion, while a wide distribution of random couplings destroys the collective effects.

description: This paper has examined the spatial integration, price dynamics, and pricing behavior of wheat markets in Ethiopia using 72 months retail price series (July 2001-June 2007) and cross-section data of structural determinants of spatial integration. Dynamic measures of spatial integration including long-run multipliers, speed of spatial price adjustment, and composite index were estimated to measure the magnitude, speed, and extent of spatial linkages and to identify the relative importance and pricing conduct in these markets. The common assertion that Addis Ababa is a central market dictating commodity price formation process in Ethiopia was disproved. Nazreth wheat market was found to be the center of price discovery in the country by dictating price formation in supply markets. The three hypothesized oligopolistic pricing behavior of wheat markets— spatial price discrimination, instantaneous and cooperative pricing, and perfect price matching — were tested. The two hypotheses that wheat markets exercise spatial price discrimination and cooperative pricing were rejected. However, the hypothesis of spatial price discrimination was accepted for some markets trading with Addis Ababa and Nazreth. This is verified to be the result of price discrimination exercised in Addis Ababa and the response of supply markets against the conduct in the destination markets. Supply markets with alternative market outlets were trying to establish short-run market independence depending on the pricing conduct prevalent in the destination markets while those without alternative market outlets were victims of the pricing behavior. This is an indication of inefficient pricing system prevalent in the wheat marketing system. Structural determinants of spatial market integration including inter-market road distance, road density, dissimilarity in per capita wheat production, and dissimilarity in population density were estimated and tested for their possible effect on the level, speed and extent of market integration to identify alternative market development interventions. Except for population density, all the selected factors of market integration were found to significantly determine market integration in Ethiopia. The spatial integration of Ethiopian wheat markets was found to be generally low in magnitude and sluggish in speed because of lack of flexibility and responsiveness of the marketing system.

description: An analysis of the Schwinger's action principle in Lagrangian quantum field theory is presented. A solution of a problem contained in it is proposed via a suitable definition of a derivative with respect to operator variables. This results in a preservation of Euler-Lagrange equations and a change in the operator structure of conserved quantities. Besides, it entails certain relation between the field operators and their variations (which is identically valid for some fields, e.g. for the free ones). The general theory is illustrated on a number of particular examples

description: Purpose: While flexible endoscopic evaluation of swallowing (FEES) is a common clinical procedure used in the head and neck cancer (HNC) population, extant outcome measures for FEES such as bolus-level penetration–aspiration and residue scores are not well suited as global patient-level endpoint measures of dysphagia severity in cooperative group trials or clinical outcomes research. The Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) was initially developed and validated for use during videofluoroscopic evaluations as a way to grade safety, efficiency, and overall pharyngeal swallowing impairment. The purpose of this study was to adapt and validate DIGEST for use with FEES.Method: A modified Delphi exercise was conducted for content validation, expert consensus, adaptation, and operationalization of DIGEST-FEES. Three blinded, expert raters then evaluated 100 de-identified post-HNC treatment FEES examinations. Intra- and interrater reliability were tested with quadratic weighted kappa. Criterion validity against the MD Anderson Dysphagia Inventory, Functional Oral Intake Scale, Secretion Severity Scale, and Yale Residue Rating Scale was assessed with Spearman correlation coefficients.Results: Interrater reliability was almost perfect for overall DIGEST-FEES grade (κw = 0.83) and safety grade (κw = 0.86) and substantial for efficiency grade (κw = 0.74). Intrarater reliability was excellent for all raters (0.9–0.91). Overall DIGEST-FEES grade correlated with MD Anderson Dysphagia Inventory (r = −.43, p < .0001), Functional Oral Intake Scale (r = −.43, p < .0001), Secretion Severity Scale (r = .47, p < .0001), Yale Vallecular Residue (r = .73, p < .0001), and Yale Pyriform Sinus Residue (r = .65, p < .0001).Conclusion: DIGEST-FEES is a valid and reliable scale to describe the severity of pharyngeal dysphagia in patients with HNC.

description: In this article we focus on the propagation of a beam of particles guided by a transversely confining potential. We consider different regimes. In the classical regime, we describe the beam by means of a set of hydrodynamic-like equations. We apply this formalism in order to investigate two practical ways for increasing the collision rate: by using a constriction or by tilting the guide. A high enough collision rate is indeed the most crucial prerequisite for reaching the quantum degenerate regime by means of evaporative cooling. In the quantum regime, we study the propagation of bosonic atoms through a constriction in two opposite regimes: the collision-less one and the Thomas-Fermi one.

 Notes. Oryzaephilus gibbosus is widespread in Africa but has not previously been recorded from Socotra. In the past it was found on East African coconuts and coconut shell (AITKEN 1965) imported to the United Kingdom. It has also been found on other oilseeds, sifted from compost, and caught in a soil trap (HALSTEAD 1980). Some notes on characters for distinguishing O. gibbosus and O. socotraensis sp. nov. are included in the differential diagnosis for the latter species. In addition, O. gibbosus males have a spine on the metafemora, as well as the other secondary sexual characters of the hind legs. The typical form of the parameres and median lobe of this species is illustrated in Fig. 7. For additional line illustrations of O. gibbosus and its genitalia, see HALSTEAD (1980, 1993).

description: Coronal mass ejections (CMEs) are tightly related to filament eruptions and usually are their continuation in the upper solar corona. It is common practice to divide all observed CMEs into fast and slow ones. Fast CMEs usually follow eruptive events in active regions near big sunspot groups and associated with major solar flares. Slow CMEs are more related to eruptions of quiescent prominences located far from active regions. We analyze ten eruptive events with particular attention to the events on 2013 September 29 and on 2016 January 26, one of which was associated with a fast CME, while another was followed by a slow CME. We estimated the initial store of free magnetic energy in the two regions and show the resemblance of pre-eruptive situations. The difference of late behaviour of the two eruptive prominences is a consequence of the different structure of magnetic field above the filaments. We estimated this structure on the basis of potential magnetic field calculations. Analysis of other eight events confirmed that all fast CMEs originate in regions with rapidly changing with height value and direction of coronal magnetic field.

description: Global Positioning System (GPS) technology has changed the world. We now rely on it to navigate our vehicles, source real-time information about chosen locations and to track our movements. GPS is, however, principally limited to receiving signals outdoors and therefore not able to provide reliable information about indoor movements. This paper examines patterns of indoor physical activity and sedentary behaviour using a combination of lifelogging and GPS movement data to develop an index for capturing activity changes. In our preliminary analysis, we explore possible associations between people’s indoor physical activity levels and their socio-demographic characteristics.

description: The goal of transfer learning is to improve the performance of target learning task by leveraging information (or transferring knowledge) from other related tasks. In this paper, we examine the problem of transfer distance metric learning (DML), which usually aims to mitigate the label information deficiency issue in the target DML. Most of the current Transfer DML (TDML) methods are not applicable to the scenario where data are drawn from heterogeneous domains. Some existing heterogeneous transfer learning (HTL) approaches can learn target distance metric by usually transforming the samples of source and target domain into a common subspace. However, these approaches lack flexibility in real-world applications, and the learned transformations are often restricted to be linear. This motivates us to develop a general flexible heterogeneous TDML (HTDML) framework. In particular, any (linear/nonlinear) DML algorithms can be employed to learn the source metric beforehand. Then the pre-learned source metric is represented as a set of knowledge fragments to help target metric learning. We show how generalization error in the target domain could be reduced using the proposed transfer strategy, and develop novel algorithm to learn either linear or nonlinear target metric. Extensive experiments on various applications demonstrate the effectiveness of the proposed method.

 Diagnosis. Members of this genus are distinguished by the elongate-oval body form; the large rounded head, with coarsely faceted, holoptic or nearly holoptic eyes that are often contiguous or separated at the midline in frontal view by no more than the diameter of an ocellus; broad frons; the four to six bristlelike setae on the hind margin of each eye; protruding genae forming wide “cheeks”; long labium extending to middle of abdomen or beyond; short barrel-shaped segment I, and cylindrical antennal segment II, slightly thicker and more pubescent in males than females, and the short, slender, fusiform segments III and IV; usually punctate, trapeziform pronotum with indistinct calli, carinate lateral margins, and a sinuate posterior margin; broadly exposed mesoscutum; equilateral scutellum; entire, moderately laterally convex hemelytra, ranging from uniformly ttranslucent white to dark brown or black, often with white markings; and saltatorial hind femora.
 Male genitalia are minimally useful for distinguishing most species of Isometopinae. In Myiomma, the parameres (Figs. 21–23) are relatively simple; the left paramere is largest, C-shaped, bulbous basally, and slender distally; the right paramere is smaller, more slender, distally acute, and somewhat sword-shaped. The vesica is membranous, lacking sclerotized structures, and has only a simple gonoporal opening. As a consequence, we have refrained from dissecting unique holotypes for this study until more material can be obtained.
 Discussion. Previously, 59 species of Myiomma were known worldwide (Schuh 1995; Herczek 1993; Akingbohungbe 1996, 2003), including 10 from the Western Hemisphere (Henry 1979, 1984). With the description of seven new species in this paper, 17 New World Myiomma are now known.

description: Recent investigations by Bender and Boettcher (Phys. Rev. Lett 80, 5243 (1998)) and Mezincescu (J. Phys. A. 33, 4911 (2000)) have argued that the discrete spectrum of the non-hermitian potential $V(x) = -ix^3$ should be real. We give further evidence for this through a novel formulation which transforms the general one dimensional Schrodinger equation (with complex potential) into a fourth order linear differential equation for $|Ψ(x)|^2$. This permits the application of the Eigenvalue Moment Method, developed by Handy, Bessis, and coworkers (Phys. Rev. Lett. 55, 931 (1985);60, 253 (1988a,b)), yielding rapidly converging lower and upper bounds to the low lying discrete state energies. We adapt this formalism to the pure imaginary cubic potential, generating tight bounds for the first five discrete state energy levels.

The analysis covered the period from 2008 to 2012, including the global crisis and post-crisis situation in Poland, which accompanied it. The conducted research shows that the processes of adjustment of supply to market demand include: changes in the profi le of manufacturing enterprises, rationalisation of behaviour in the sphere of production and resource management. For the research two branches: fat and dairy products, which are diverse in terms of supply and demand and concentration of production. This paper focuses on the production and revenue concentration in the branches of the food industry selected for the study. The study used a rich empirical material based on both the author’s own research and secondary sources.

description: Growth rates of State Domestic products from agriculture were high for many states during the 1990’s. However, growth decelerated in all the states except Madhya Pradesh during the period 2000’s. The deceleration is the highest in the states with greater proportion of rain-fed areas (Gujarat, Rajasthan, M.P., Karnataka and Maharashtra). Recent experience, however, shows that Gujarat recorded the highest growth of around 9 per cent during 2000/01 to 2007/08. During this period, six states viz., Gujarat, Rajasthan, Himachal Pradesh, Andhra Pradesh, Chhattisgarh and Bihar recoded more than 4 per cent growth per annum. Public investment in infrastructure like irrigation, power, roads, watersheds, check dams,technology like BT cotton and diversification in agriculture played crucial roles in raising agricultural growth in Gujarat. Other states can learn from the experience of Gujarat. There is a need to shift rice cultivation to Eastern region from Punjab and Haryana for growth, equity and environment reasons. In order to encourage the States to invest more towards agriculture and allied sectors and to achieve 4 per cent growth in agriculture, the government launched the Rashtriya Krishi Vikas Yojana (RKVY) in 2007-08 with an outlay of Rs.25, 000 crores for the 11th Five Year Plan. The scheme requires the States to prepare District agriculture plans and provides adequate flexibility and autonomy to State governments. The States should make use of this scheme to improve the agriculture sector.

description: In 1973, E. T. Newman considered the holomorphic extension \tilde E(x+iy) of the Coulomb field E(x) in R^3. By analyzing its multipole expansion, he showed that the real and imaginary parts of \tilde E(x+iy), viewed as functions of x for fixed y, are the electric and magnetic fields generated by a spinning ring of charge R. This represents the electromagnetic part of the Kerr-Newman solution to the Einstein-Maxwell equations. As already pointed out by Newman and Janis in 1965, this interpretation is somewhat problematic since the fields are double-valued. To make them single-valued, a branch cut must be introduced so that R is replaced by a charged disk D having R as its boundary. In the context of curved spacetime, D becomes a spinning disk of charge and mass representing the singularity of the Kerr-Newman solution. Here we confirm the above interpretation of the real and imaginary parts of \tilde E(x+iy) by computing the charge- and current densities directly as distributions in R^3 supported in the source disk D. This shows in particular that D spins rigidly at the critical rate, so that its rim R moves at the speed of light. It is a pleasure to thank Ted Newman, Andrzej Trautman and Iwo Bialinicki-Birula for many instructive discussions, particularly in Warsaw and during a visit to Pittsburgh.

description: Much of our knowledge about dynamics and functionality of molecular systems has been achieved with femtosecond time-resolved spectroscopy. Despite extensive technical developments over the past decades, some classes of systems have eluded dynamical studies so far. Here, we demonstrate that superfluid helium nanodroplets, acting as thermal bath of 0.4 K temperature to stabilize weakly bound or reactive systems, are well suited for time-resolved studies of single molecules solvated in the droplet interior. By observing vibrational wavepacket motion of indium dimers (In$_2$) for over 50 ps, we demonstrate that the perturbation imposed by this quantum liquid can be lower by a factor of 10-100 compared to any other solvent, which uniquely allows to study processes depending on long nuclear coherence in a dissipative environment. Furthermore, tailor-made microsolvation environments inside droplets will enable to investigate the solvent influence on intramolecular dynamics in a wide tuning range from molecular isolation to strong molecule-solvent coupling.

description: In several familiar subcategories of the category ${\mathbb T}$ of topological spaces and continuous maps, embeddings are not pushout-stable. But, an interesting feature, capturable in many categories, namely in categories $\mathcal{B}$ of topological spaces, is the following: For $\mathcal{M}$ the class of all embeddings, the subclass of all pushout-stable $\mathcal{M}$-morphisms (that is, of those $\mathcal{M}$-morphisms whose pushout along an arbitrary morphism always belongs to $\mathcal{M}$) is of the form $A^{Inj}$ for some space $A$, where $A^{Inj}$ consists of all morphisms $m:X \to Y$ such that the map $Hom(m,A): Hom(Y,A) \to Hom(X,A)$ is surjective. We study this phenomenon. We show that, under mild assumptions, the reflective hull of such a space $A$ is the smallest $\mathcal{M}$-reflective subcategory of $\mathcal{B}$; furthermore, the opposite category of this reflective hull is equivalent to a reflective subcategory of the Eilenberg-Moore category $Set^{\mathbb T}, where ${\mathbb T}$ is the monad induced by the right adjoint $Hom(-,A): {\mathbb T}^{op} \to Set$. We also find conditions on a category $\mathcal{B}$ under which the pushout-stable $\mathcal{M}$-morphisms are of the form $\mathcal{A}^{Inj}$ for some category $\mathcal{A}$.

description: The main goal of this paper was to identify the process of sales and organisation of transport of farm products, including a division into product groups in farms in Wielkopolskie voivodeship. The research on a group of 184 farms led to the following conclusions: wheat was the most frequent product sold by farms in the plant production category; more than 70% of the farms used their own transport to deliver agricultural products to their consignees, third party transport was mostly used to deliver pork and beef livestock; there was diversity in the distance from farms to buying stations, depending on individual products sold

description: The local structure of (Al_0.06V_0.94)_2O_3 in the paramagnetic insulating (PI) and antiferromagnetically ordered insulating (AFI) phase has been investigated using hard and soft x-ray absorption techniques. It is shown that: 1) on a local scale, the symmetry of the vanadium sites in both the PI and the AFI phase is the same; and 2) the vanadium 3d - oxygen 2p hybridization, as gauged by the oxygen 1s absorption edge, is the same for both phases, but distinctly different from the paramagnetic metallic phase of pure V_2O_3. These findings can be understood in the context of a recently proposed model which relates the long range monoclinic distortion of the antiferromagnetically ordered state to orbital ordering, if orbital short range order in the PI phase is assumed. The measured anisotropy of the x-ray absorption spectra is discussed in relation to spin-polarized density functional calculations.

description: The food industry is one of the traditional areas of management, the so-called low-tech. For this reason, technological and spatial proximity may be the key to create new solutions in the Polish food industry. The main objective of the study was an attempt to seek infl uence of relationships with suppliers on innovation activities of enterprises in the food industry in Poland. As a consequence, this would allow to determine the boundary conditions for the model structure of innovation networks within producers of food and beverages, with special reference to the Polish economy. The study was conducted on a group of 631 companies food industry companies located in Poland. Methodical part of the analysis was based on probit regression (probability theory).

description: We present a study of the magnetic properties of YNiO$_{3}$ in the paramagnetic range, above and below the metal-insulator (MI) transition. The dc susceptibility, $χ_{dc}$ (measured up to 1000 K) is a decreasing function of T for $T >$150 K (the Néel temperature) and we observe two different Curie-Weiss regimes corresponding to the metallic and insulator phases. In the metallic phase, this behaviour seems to be associated with the small ionic radius of Y% $^{3+}$. The value of the Curie constant for T$
