description: Enhancing agricultural productivity through the adoption of proven technologies presents a credible pathway to economic development and poverty reduction. The adoption of improved chickpea varieties in Ethiopia has the potential to contribute not only to food security but also to economic development as well as poverty reduction among the poor. We analyze the impacts of improved chickpea adoption on smallholder production and commercialization employing a triple hurdle (TH) model on a panel data of three rounds (2008, 2010, 2014), drawn from 614 households in potential chickpea areas in Ethiopia. The correlated random effect model coupled with the control function approach for non-linear panel models was employed to address heterogeneity and endogeneity. The adoption of improved chickpea varieties shows a significant positive effect on the commercialization of chickpea. This study therefore affirms the importance of improved chickpea varieties for commercialization and additionally provides support for policies targeting poverty alleviation in rural areas through targeting more novel farm technologies, improving extension services and increasing access to land especially by the young.

description: After many years of neglect, there is a renewed interest in agricultural mechanization in Africa. This paper analyzes an initiative of the company John Deere and its dealer AFGRI to promote smallholder mechanization in Zambia. The analysis focuses on the impact of this initiative on smallholder farmers who receive tractor services and on the demand for hired labor. The results of a Propensity Score Matching (PSM) analysis indicate that farmers who access tractor services for land preparation can almost double their income by cultivating a much larger share of the land that they own. The analysis also suggests that the increased income is used for children s education and for purchasing more food, but does not result in increased food diversity. The findings indicate that the demand for hired labor increases due to the expansion of the cultivated area and due to a shift from family labor, including that of children, to hired labor. Questions that require further investigation are identified, including strategies to increase the incentives of tractor owners to provide services to smallholders; and strategies to avoid new forms of dependency of agricultural laborers that may result from a shift in the timing of the labor demand.

description: We present the spectral analysis of bright steady states in an outburst of the transient neutron star low-mass X-ray binary (NS-LMXB) Swift J1858.6-0814 observed with NICER. We detected an ionized iron K absorption line (H-like Fe) at 6.97keV in the spectrum. We estimated the photoionization parameter using the ratio of the equivalent widths (EWs) of the FeXXVI (H-like) (17+\-5eV) and FeXXV (He-like) (<3eV) and discuss the origin of the iron absorption line. The irradiated gas producing the absorption line would locate within (3-6)*1E9cm from the X-ray source. We suggest that the observed H-like Fe absorption line originates from the highly-ionized gas in the inner accretion disk in Swift J1858.6-0814.

description: Pairing gaps for fermionic atoms in harmonic oscillator traps are calculated for a wide range of interaction strengths and particle number, and compared to pairing in nuclei. Especially systems, where the pairing gap exceeds the level spacing but is smaller than the shell splitting $\hbarω$, are studied which applies to most trapped Fermi atomic systems as well as to finite nuclei. When solving the gap equation for a large trap with such multi-level pairing, one finds that the matrix elements between nearby harmonic oscillator levels and the quasi-particle energies lead to a double logarithm of the gap, and a pronounced shell structure at magic numbers. It is argued that neutron and proton pairing in nuclei belongs to the class of multi-level pairing, that their shell structure follows naturally and that the gaps scale as $\sim A^{-1/3}$ - all in qualitative agreement with odd-even staggering of nuclear binding energies. Pairing in large systems are related to that in the bulk limit. For large nuclei the neutron and proton superfluid gaps approach the asymptotic value in infinite nuclear matter: $Δ\simeq 1.1$ MeV.

description: The parameterized post-Einsteinian formalism was developed to search for generic deviations from general relativity with gravitational waves. We here present constraints on this framework using Bayesian analysis of a set of binary pulsar observations. In particular, we use measurements of the Keplerian and post-Keplerian parameters of six different binary pulsar systems, and Markov-Chain Monte-Carlo exploration to calculate posteriors on the parameterized post-Einsteinian parameters and derive robust constraints. We find improvements of 1-2 orders of magnitude in the strength of constraints when combining all six observations, relative to what one can achieve when using only the double binary pulsar. We also find that the constraints are robust to covariances with the binary's component masses. The bounds on the parameterized post-Einsteinian framework derived here could be used as a prior in future Bayesian tests of general relativity with gravitational wave observations.

description: Inpainting focuses on filling missing or corrupted regions of an image to blend seamlessly with its surrounding content and style. While conditional diffusion models have proven effective for text-guided inpainting, we introduce the novel task of multi-mask inpainting, where multiple regions are simultaneously inpainted using distinct prompts. Furthermore, we design a fine-tuning procedure for multimodal LLMs, such as LLaVA, to generate multi-mask prompts automatically using corrupted images as inputs. These models can generate helpful and detailed prompt suggestions for filling the masked regions. The generated prompts are then fed to Stable Diffusion, which is fine-tuned for the multi-mask inpainting problem using rectified cross-attention, enforcing prompts onto their designated regions for filling. Experiments on digitized paintings from WikiArt and the Densely Captioned Images dataset demonstrate that our pipeline delivers creative and accurate inpainting results. Our code, data, and trained models are available at https://cilabuniba.github.io/i-dream-my-painting.

description: We present a numerical method for studying the normal modes of accretion flows around black holes. In this first paper, we focus on two-dimensional, viscous, hydrodynamic disks, for which the linear modes have been calculated analytically in previous investigations. We use pseudo-spectral methods and low storage Runge-Kutta methods to solve the continuity equation, the Navier-Stokes equation, and the energy equation. We devise a number of test problems to verify the implementation. These tests demonstrate the ability of spectral methods to handle accurately advection problems and to reproduce correctly the stability criteria for differentially rotating hydrodynamic flows. They also show that our implementation is able to handle sound wave correctly with non-reflective boundary conditions, to recover the standard solution for a viscous spreading ring, and produce correctly the Shakura-Sunyaev steady disk solution. Finally, we have applied our algorithm to the problem of a non-axisymmetric viscous spreading ring and verify that such configuration is unstable to non-antisymmetric perturbations.

description: The Cahn--Hilliard equation is one of the most common models to describe phase separation processes of a mixture of two materials. For a better description of short-range interactions between the material and the boundary, various dynamic boundary conditions for the Cahn--Hilliard equation have been proposed and investigated in recent times. Of particular interests are the model by Goldstein, Miranville and Schimperna (Physica D, 2011) and the model by Liu and Wu (Arch.~Ration.~Mech.~Anal., 2019). Both of these models satisfy similar physical properties but differ greatly in their mass conservation behaviour. In this paper we introduce a new model which interpolates between these previous models, and investigate analytical properties such as the existence of unique solutions and convergence to the previous models mentioned above in both the weak and the strong sense. For the strong convergences we also establish rates in terms of the interpolation parameter, which are supported by numerical simulations obtained from a fully discrete, unconditionally stable and convergent finite element scheme for the new interpolation model.

description: We analyze a lattice model closely related to the one-dimensional inelastic gas with periodic boundary condition. The one-dimensional inelastic gas tends to form high density clusters of particles with almost the same velocity, separated by regions of low density; plotted as a function of particle indices, the velocities of the gas particles exhibit sharp gradients, which we call shocks. Shocks and clusters are seen to form in the lattice model too, although no true positions of the particles are taken into account. The locations of the shocks in terms of the particle index show remarkable independence on the coefficient of restitution and the sequence of collisions used to update the system, but they do depend on the initial configuration of the particle velocities. We explain the microscopic origin of the shocks. We show that dynamics of the velocity profile inside a cluster satisfies a simple continuum equation, thereby allowing us to study cluster-cluster interactions at late times.

description: U.S.-based transnational corporations (TNCs) and single-nation corporations (SNCs) are shown to occupy two distinct sectors, core and periphery, in a dual economy. The sectors are differentiated by the competitive regimes characteristic of each. The TNC-core group is located predominantly in the technologically advanced, capital-intensive, rapidly growing industries, and invests more intensively than do SNCs in research and development, advertising and marketing, and new plant and equipment. In addition, the greater ability of TNCs to deploy international and inter-industry capital flows within the firm creates a tendency toward greater and more homogeneous profit and growth rates than is characteristic of SNCs. The empirical work presented here breaks new ground in several ways. The economic rate of return on assets is measured by adjusting the book value of assets to reflect replacement value; total return includes returns to both equity and finance, and is measured net of industry-specific economic depreciation instead of tax-based depreciation. Regression analysis on firm-level data incorporating the effects of international operations is new, since the few studies that have included international data have most often been performed on industry- or line of business-level data. No previous work has specifically tested for the impact of the different competitive regimes characteristic of the two groups on profit performance.

This simulation showed the formation of a disk-like structure and the generation of a jet-like outflow inside the shock wave launched at the core bounce. We have found the jet is accelerated by the magnetic pressure and the centrifugal force and is collimated by the pinching force of the toroidal magnetic field amplified by the rotation and the effect of geometry of the poloidal magnetic field. The maximum velocity of the jet is mildly relativistic ($\sim$ 0.3 c).

Effective Field Theory for Noncommutative Spacetime: A Toy Model
Creators: name: Ghosh, Subir
Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A novel geometric model of a noncommutative plane has been constructed. We demonstrate that it can be construed as a toy model for describing and explaining the basic features of physics in a noncommutative spacetime from a field theory perspective. The noncommutativity is induced internally through constraints and does not require external interactions. We show that the noncommutative space-time is to be interpreted as having an {\it internal} angular momentum throughout. Subsequently, the elementary excitations - {\it i.e.} point particles - living on this plane are endowed with a {\it spin}. This is explicitly demonstrated for the zero-momentum Fourier mode. The study of these excitations reveals in a natural way various {\it stringy} signatures of a noncommutative quantum theory, such as dipolar nature of the basic excitations \cite{jab} and momentum dependent shifts in the interaction point \cite{big}. The observation \cite{sw} that noncommutative and ordinary field theories are alternative descriptions of the same underlying theory, is corroborated here by showing that they are gauge equivalent. Also, treating the present model as an explicit example, we show that, even classically, in the presence of additional constraints, (besides the usual ones due to reparameterization invariances), the equivalence between Nambu-Goto and Polyakov formulations is subtle.

description: Particle-based simulations of discontinuous shear thickening (DST) and shear jamming (SJ) suspensions are used to study the role of stress-activated constraints, with an emphasis on resistance to gear-like rolling. Rolling friction decreases the volume fraction required for DST and SJ, in quantitative agreement with real-life suspensions with adhesive surface chemistries and "rough" particle shapes. It sets a distinct structure of the frictional force network compared to only sliding friction, and from a dynamical perspective leads to an increase in the velocity correlation length, in part responsible for the increased viscosity. The physics of rolling friction is thus a key element in achieving a comprehensive understanding of strongly shear-thickening materials.

The moral judgment of attorneys: Employment in the public or the private sector and courses in legal ethics
Creators: name: Long, Virginia Anne
Publisher: name: American University
Year: 2023

description: The purpose of the study was to determine the level of moral judgment of a sample of attorneys, as assessed by the Defining Issues Test (DIT), and to ascertain differences, if any, in the level of moral judgment of these attorneys classified by each public versus private employment and number of ethics courses they completed. Hypotheses guiding the study posited that the mean DIT score (level of moral judgment) of the study sample of attorneys employed in the public sector would be significantly (p $\le$.05) higher than that of those employed in the private sector and that there would be a significant (p $\le$.05) positive relationship between the number of legal ethics courses completed and the level of moral judgment in the study sample of attorneys. Three hundred attorneys were selected for participation in the study: 150 were selected from a national directory of legal aid offices, and 150 were chosen from law firms that were listed as having the highest yearly gross revenues in the United States. Two instruments were employed to collect study data from the participants: the Defining Issues Test, a measure of moral judgment which presents hypothetical moral dilemmas, and the Socio-Demographic Questionnaire, an instrument which elicits biographical information. Useable study instruments from 119 subjects provided the data for statistical analysis. Study findings supported the conclusion that, in the study sample of attorneys, those working in the public sector had significantly higher moral judgment levels (i.e., mean P scores as measured by the DIT) than those working in the private sector. Study findings relating to legal ethics courses supported the conclusion that, for the study sample of attorneys, the number of legal ethics courses completed (one through four or more) had no significant effect on level of moral judgment, as measured by the DIT. Implications of the study include the necessity of reexamining the nature and number of ethics courses required by law schools and bar associations as well as investigating the moral factors which underlie employment circumstances among attorneys.

description: While children’s experiences of online risks and harm is a growing area of research in New Zealand, public discussion on the matter has largely been informed by mainstream media’s fixation on the dangers of technology. At best, debate on risks online has relied on overseas evidence. However, insights reflecting the New Zealand context and based on representative data are still needed to guide policy discussion, create awareness, and inform the implementation of prevention and support programmes for children. This research report presents findings from a quantitative study regarding different aspects related to risks and online safety. It looks at the online experiences that children find bothersome and upsetting and explores the hurtful behaviours they encounter or engage in, both online and in person. Evidence regarding exposure to different types of potentially harmful online content is also presented. Another relevant contribution is the insights related to excessive internet use.The findings presented in this report are based on data from 2,061 New Zealand children aged 9-17. We hope the findings will contribute to the development of policies, practices and services designed to support New Zealand children to safely take advantage of the opportunities available to them online.

description: We study trace theoretic concurrent systems. This setting encompasses safe (1-bounded) Petri nets. We introduce a notion of irreducible concurrent system and we prove the equivalence between irreducibility and a "spectral property". The spectral property states a strict inequality between radii of convergence of certain growth series associated with the system. The proof that we present relies on analytic combinatorics techniques. The spectral property is the cornerstone of our theory, in a framework where the Perron-Frobenius theory does not apply directly. This restriction is an inherent difficulty in the study of concurrent systems. We apply the spectral property to the probabilistic theory of concurrent systems. We prove on the one hand the uniqueness of the uniform measure, a question left open in a previous paper. On the other hand, we prove that this uniform measure can be realized as a Markov chain of states-and-cliques on a state space that can be precisely characterized.

The moral judgment of attorneys: Employment in the public or the private sector and courses in legal ethics

subject: FOS: Psychology

description: The purpose of the study was to determine the level of moral judgment of a sample of attorneys, as assessed by the Defining Issues Test (DIT), and to ascertain differences, if any, in the level of moral judgment of these attorneys classified by each public versus private employment and number of ethics courses they completed. Hypotheses guiding the study posited that the mean DIT score (level of moral judgment) of the study sample of attorneys employed in the public sector would be significantly (p $\le$.05) higher than that of those employed in the private sector and that there would be a significant (p $\le$.05) positive relationship between the number of legal ethics courses completed and the level of moral judgment in the study sample of attorneys. Three hundred attorneys were selected for participation in the study: 150 were selected from a national directory of legal aid offices, and 150 were chosen from law firms that were listed as having the highest yearly gross revenues in the United States. Two instruments were employed to collect study data from the participants: the Defining Issues Test, a measure of moral judgment which presents hypothetical moral dilemmas, and the Socio-Demographic Questionnaire, an instrument which elicits biographical information. Useable study instruments from 119 subjects provided the data for statistical analysis. Study findings supported the conclusion that, in the study sample of attorneys, those working in the public sector had significantly higher moral judgment levels (i.e., mean P scores as measured by the DIT) than those working in the private sector. Study findings relating to legal ethics courses supported the conclusion that, for the study sample of attorneys, the number of legal ethics courses completed (one through four or more) had no significant effect on level of moral judgment, as measured by the DIT. Implications of the study include the necessity of reexamining the nature and number of ethics courses required by law schools and bar associations as well as investigating the moral factors which underlie employment circumstances among attorneys.

Homeownership, well-being, class and politics: Perceptions of American homeowners and renters
Creators: name: Vitt, Lois A.
Publisher: name: American University
Year: 2023

description: This research brings into focus the social psychological dimensions of housing and extends the scholarship on homeownership and housing theory in the United States. It has examined certain widespread assumptions made popular by the "get ahead" theories inherent in the American Dream. GSS survey data for the years 1985 through 1991 are employed to detect differences in the perceptions of homeowners and renters using a quality of life (QOL) approach to measure subjective well-being; a subjective social class measure to test for feelings of being "middle class" and various measures to determine whether homeowners are more "conservative" than renters. The conventional wisdom about homeownership and increased well-being is supported by the results. Homeowners experience significantly higher feelings of family satisfaction than renters; they are more satisfied with leisure time activities; and they are more satisfied than renters with their financial condition. Homeowners, in general, feel significantly happier than renters. The belief that homeownership enhances feelings of social status is also supported. Homeowners see themselves as "middle class" more often than renters, signifying their feelings of enhanced social status. The effect of homeownership remains significant, although modest, for workers when tested for differences using an objective class measure. Homeowners perceive themselves as "conservative" more often than renters, but tests on additional measures of left-right political attitudes failed to uncover any further differences between the political views of homeowners and renters. The conceptualization of a new housing theory emerged from the research and is presented to provide a reframed and expanded way of looking at housing and homeownership. In the U.S., symbolic concepts of home and ownership are linked. They were intensified by political and business interests through explicit housing policy that benefited a growing population and formed housing norms that now permeate American culture. Policymakers now hold the key to the ability of private housing markets to innovate and to the future housing tenure choices of Americans. In light of the research results, housing policy should seek to reverse the nation's falling homeownership rate and to enable more renting Americans to become homeowners.
Searching for massive clusters in weak lensing surveys

description: We explore the ability of weak lensing surveys to locate massive clusters. We use both analytic models of dark matter halos and mock weak lensing surveys generated from a large cosmological N-body simulation. The analytic models describe average properties of weak lensing halos and predict the number counts, enabling us to compute an effective survey selection function. We test the model prediction for the peak number counts in weak lensing mass maps against the mock numerical data, and find that the noise due to intrinsic galaxy ellipticities causes a systematic effect which increases the peak counts. We develop a correction scheme for the systematic effect in an empirical manner, and show that, after the correction, the model prediction agrees well with the mock data. The mock data is also used to examine the completeness and efficiency of the weak lensing halo search with fully taking into account the noise and the projection effect by large-scale structures. We show that the detection threshold of S/N=4-5 gives an optimal balance between completeness and efficiency. Our results suggest that, for a weak lensing survey with a galaxy number density of ng=30/arcmin^2 with a mean redshift z=1, the mean number of peaks in the 10sq deg area is N_peak=62 for a detection threshold S/N=4. The contamination rate is 42%, and thus, on average, 36 out of 62 peaks (at least) are signals from real halos. Weak lensing surveys thus provide a reasonably efficient way to searching for massive clusters.

description: In this work, the mode I fracture toughness of dissimilar metal-composite adhesive joints is experimentally investigated using the double cantilever beam (DCB) test. The particular joint under study is resulted by the adhesive joining of a thin titanium sheet with a thin carbon fiber reinforced plastic (CFRP) laminate and is envisioned to be implemented in the hybrid laminar flow control system of future aircraft. Four different industrial technologies for the joining of the titanium and CFRP adherents are evaluated/compared; co-bonding with and without adhesive and secondary bonding using either thermoset or thermoplastic CFRP. The vacuum-assisted resin transfer molding (VARTM) technique is employed for the manufacturing of the panels. After manufacturing, the panels are cut into test specimens that, because they are too thin (approximately 2.4 mm thick), needed to be stiffened from both titanium and composite sides with two aluminum backing beams to ensure the non-yielding of the titanium during the subsequent DCB tests. Towards the determination of the fracture toughness of the joint from the experimental data, an analytical model recently developed by the authors, that considers the bending-extension coupling of both sub-laminates constituting the test specimen as well as the manufacturing-induced residual thermal stresses, is applied. For the four manufacturing options (MO) investigated, the load-displacement behaviors, failure patterns, and fracture toughness performances are presented and compared.
