description: Sheep and goat farming is a profitable and sustainable enterprise to different categories of rural households. The study was conducted in Karnataka state of India. The results revealed that majority of the sheep and goat farmers belonged to age group of above 40 years and were illiterate (50-52%) and maximum number of farmers were having income of less than Rs.1 lakh per annum, who belonged to backward class, scheduled caste and scheduled tribe. The results also revealed that the annual net returns per animal of goat farm was relatively higher (Rs.1980) compared to sheep (Rs.1507) farming. Among sheep herd size, the net returns was more in large (Rs.1772) herd size as compared to medium (Rs.1431) and small (Rs.1008) herd size. Similarly, net returns was higher (Rs.2138) in large flock size compared to medium (Rs.1962) and small (Rs.1513). The mean technical efficiency of goat farming (92%) was relatively higher compared to sheep farming (89%). Non availability of grazing land with high cost of feed, especially during summer, incidence of PPR, ET and FMD diseases were the major constraints in sheep and goat rearing as perceived by the farmer. Keywords: Sheep herd, Goat flock, net returns, Technical efficiency Acknowledgement : Authors sincerely thank Dr. Suresh S Patil, Dean(Agriculture), University of Agricultural Sciences, Raichur, for his guidance and valuable suggestions during the course of this study; and to Mr. Ravi, S.

Monetary shocks and nominal exchange rate dynamics. Monetary and exchange market pressure models: Evidence from Bulgaria
Creators: name: Assenov, Assen
Publisher: name: American University
Year: 2023

description: This dissertation is an empirical study of the role of monetary police in the exchange rate dynamics of a small country transitioning to an open market economy. In particular, this study analyzes the role of monetary policy in the process that led to collapse of the Bulgarian currency at the end of 1996 and beginning of 1997 and led to the introduction of currency board. First, this research uses a flexible price monetary approach model to estimate the role of the monetary policy in the dynamics of the exchange rate of the Bulgarian currency. Second, we use the VAR and SVAR specifications of the exchange-market-pressure model to investigate the stand of Bulgarian monetary policy and its effect on the exchange rate. The exchange-market-pressure model is a natural combination of the monetary approach to the balance of payment and the monetary approach to exchange rate determination. The model predicts that the flow of excess supply of money under flexible exchange rate will lead to an increase of exchange market pressure, which measures the exchange-rate depreciation and official exchange-market intervention. The main findings of the research suggest that the dynamic responses of exchange-market pressure to monetary policy shocks are consistent with standard monetary theory: domestic credit shocks provide additional liquidity to the banking system and increase the exchange-market pressure. Monetary policy shocks led to increased exchange market pressure and the collapse of the Bulgarian lev, and it resulted in the adoption of a currency board on July 1, 1997. The currency board restrained the expansionary monetary policy which in turn reduced the exchange-market pressure and, along with fiscal macroeconomic policy, restored the credibility of the national currency and stabilized the financial system. Bulgaria's unfortunate experience of a collapsed national currency is relevant to the choice of monetary policy for many countries in transition and emerging markets today.

description: The problems of agriculture affect mostly the smallholder farmers who have small fields in different places. Group-farming cooperatives serves as good alternative to boost food production as well as lifting people out of poverty. In this study we used a recent survey data in Nigeria to examine the effect of membership of group-farming cooperatives on food production and poverty status. Probit regression model estimate is used to analyse the decision to join group-farming cooperatives and the effect of membership of group-farming cooperatives on poverty status and ordinary least square is employed to examine the effect of membership of group-farming cooperatives on food production and productivity of farmers. We find that, group-farming cooperatives have positive and statistically significant effect on food proction at 5% level of significance; prevalence of poverty is higher among non-members of group-farming cooperatives. Being a member of other forms of cooperative also helps to reduce poverty among the farming households. Therefore, we recommend that both the government and non-governmental organization should develop strategies that will encourage participation in group-farming cooperatives and also create more awareness among farming households, which can motivate more farmers to partake in this form of farmers organizations.

description: We propose a novel approach to capture risk and risk aversion for agricultural technology adoption by integrating second order stochastic dominance in a farm-level model based on real options. We employ an illustrative case study of perennial energy crop adoption. In our example, we found that risk aversion leads to smaller and earlier adoption of a new technology; in contrast, higher subjective riskiness increases expected scale and first slow down and then accelerate adoption. Those effects would have been obscured if technology adoption would have been considered as standing-alone or as now-or-never decision. Acknowledgement :

description: We present a model that gives a natural explanation to the charged lepton mass hierarchy and study the contributions to the electron and the muon $g-2$. In the model, we introduce lepton-flavor-dependent $U(1)_F$ symmetry and three additional Higgs doublets with $U(1)_F$ charges, to realize that each generation of charged leptons couples to one of the three additional Higgs doublets. The $U(1)_F$ symmetry is softly broken by $+1$ charges, and the smallness of the soft breaking naturally gives rise to the hierarchy of the Higgs VEVs, which then accounts for the charged lepton mass hierarchy. Since electron and muon couple to different scalar particles, each scalar contributes to the electron and the muon $g-2$ differently. We survey the space of parameters of the Higgs sector and find that there are sets of parameters that explain the muon $g-2$ discrepancy. On the other hand, we cannot find the parameter sets that can explain $g-2$ discrepancy within 2$σ$. Here the $U(1)_F$ symmetry suppresses charged lepton flavor violation.

description: Unregulated groundwater extraction has led to declining water tables and increasing water scarcity in the Indian subcontinent. Understanding how farmers respond to this scarcity is important from multiple perspectives - equity in access, livelihoods security and resource sustainability. We present a case from the rapidly urbanizing Arkavathy sub-basin near Bangalore city in Southern India where irrigation is fully groundwater dependent. Using cross-sectional data from a stratified random sample of 333 farmers from 15 villages, we investigated the factors that determine their choice of crops under conditions of water scarcity and urbanization. Binary logit analysis showed that the high land holding farmers respond by tapping deep groundwater using borewells. Multinomial logit analysis revealed that access to groundwater, variation in the proximity to the product market (city) and labour availability influence crop choice decisions. We observe that current responses indicate what has been characterized in literature as chasing strategies. These largely favour the well-off farmers and hence inequitable. While choice of water intensive crops and unregulated pumping have aggravated water stress, the uptake of water saving technologies among irrigated farmers has been low, showing that resource sustainability may not be a concern where non-farm diversification opportunities exist.

description: We study the effect of representation mixing in the SU(3) Skyme model by diagonalizing exactly the representation-dependent part. It is observed that even without the next-to-leading order symmetry breaking terms the low-lying baryon masses as well as the recently discovered $Θ+$ and $\Cascade_{\bar{10}}$ can be fairly well reproduced within 3% accuracy. It is also demonstrated that the mixing effect is not negligible in decay processes of $\{\bar{10}\}$. In particular the effect of mixing with $\{27\}$ is found to be quite large. These results are compatible with the second-order perturbation scheme. The decay widths are found to be sensitive to the mass values. The decay widths of $\{\bar{10}\}$ are estimated to be smaller than those of $\{10\}$ by an order of magnitude due to the destuctive interference between operators although the kinematic factors are comparable.

description: We address the generalized Nash equilibrium seeking problem in a partial-decision information scenario, where each agent can only exchange information with some neighbors, although its cost function possibly depends on the strategies of all agents. The few existing methods build on projected pseudo-gradient dynamics, and require either double-layer iterations or conservative conditions on the step sizes. To overcome both these flaws and improve efficiency, we design the first fully-distributed single-layer algorithms based on proximal best-response. Our schemes are fixed-step and allow for inexact updates, which is crucial for reducing the computational complexity. Under standard assumptions on the game primitives, we establish convergence to a variational equilibrium (with linear rate for games without coupling constraints) by recasting our algorithms as proximal-point methods, opportunely preconditioned to distribute the computation among the agents. Since our analysis hinges on a restricted monotonicity property, we also provide new general results that significantly extend the domain of applicability of proximal-point methods. Besides, the operator-theoretic approach favors the implementation of provably correct acceleration schemes that can further improve the convergence speed. Finally, the potential of our algorithms is demonstrated numerically, revealing much faster convergence with respect to projected pseudo-gradient methods and validating our theoretical findings.

The Arab League. A comparative examination of voting mechanisms: Exploration of the unanimity rule of the Arab League's regulations and how the rule affects the organization's security function

Publisher: name: American University

description: This study in International Public Law examines the impact of the League of Arab States (LAS), in the context of the legal norms of the new international order. The study analyzes the weakening influence of the League in the international political system, regarding issues of territorial sovereignty and integrity, human rights, and Arab nationalism and solidarity. It is the argument of this study that the Arab League today lacks a strong role in the implementation and enforcement of international law. This lack of influence is primarily due to its internal divisions and members' disputes regarding the norms and standards of law. While the League has proposed conventions and issued declarations modeled on the United Nation's international legal forms, it is unable to implement them internally (on issues of human rights and territorial integrity) or externally (the Arab-Israeli conflict, the Occupied Territories, Iraq-Kuwait conflict, and the US invasion of Iraq). The study draws upon published documents related to the Arab League, the UN Security Council and the African Union, to conduct an examination and comparison of the League's voting mechanisms with these other organizations. The research shows that, while the League's unanimity clause in its voting system bears primary responsibility for the League's perceived ineffectiveness in the implementing and enforcing of international law in the Middle East, these international norms of law and diplomacy are ultimately grounded in political, economic and military realities, rather than a strict adherence to statutes, treaties or resolutions. Specifically, an examination of the relevant literature shows that the League's inability to influence international norms on the Palestine question and Iraq is actually part of a larger crisis in international law and the application of such laws and norms in a way that is not even-handed.

description: In many developing countries, supermarkets are increasingly replacing traditional markets as preferred points of food purchases in urban areas. This has welfare implications on smallholder farmers that supply supermarkets. While previous studies have analyzed the welfare effects of smallholder participation in supermarket channels, many have focused on economic effects alone. Very little is known about the effects on farm household diets. Besides, most existing studies that have looked at economic effects used cross-sectional data that are limited in controlling for time-invariant differences between supermarket and traditional channel farmers. This study uses panel data from vegetable farmers in Kenya to examine the effects of supermarket contracting on farm household income and diets. The results show that supplying supermarkets has increased household income by 66%, and is associated with 8% higher consumption of calories, as well as better dietary diversity, and higher levels of zinc consumption. Using these results for simple simulations suggests that wider participation of smallholders in supermarket channels could reduce the prevalence of undernourishment by 8% and the prevalence of zinc deficiency by 12%. Hence, enhancing smallholder market access could significantly contribute to reduction of undernourishment, micronutrient malnutrition and increased income of farm households.

description: This statistical compendium presents data on U.S. agricultural exports and imports with the developed Pacific Rim countries (Japan, Taiwan, South Korea, Hong Kong, Australia, New Zealand, and Canada) for 1968-88. Export and import data are presented by quantity and value for both fiscal and calendar years. Growth in U.S. agricultural exports to the developed Pacific Rim countries between 1968 and 1988 has exceeded growth in total U.S. agricultural exports. The share of U.S. agricultural exports going to these seven countries ranged from 28 to 35 percent between 1968 and 1979 and increased steadily in the eighties to reach almost 40 percent in 1988. Taiwan and South Korea have been the fastest growing markets for U.S. agricultural exports. Nearly a quarter of U.S. imports now come from these countries. One serious limitation: U.S. data substantially understate U.S. agricultural exports to Canada because of undocumented shipments.

description: We present an analysis of the first far-ultraviolet observations of the SW Sextantis-type cataclysmic variable DW Ursae Majoris, obtained in November 2001 with the Far Ultraviolet Spectroscopic Explorer. The time-averaged spectrum of DW UMa shows a rich assortment of emission lines (plus some contamination from interstellar absorption lines including molecular hydrogen). Accretion disk model spectra do not provide an adequate fit to the far-ultraviolet spectrum of DW UMa. We constructed a light curve by summing far-ultraviolet spectra extracted in 60-sec bins; this shows a modulation on the orbital period, with a maximum near photometric phase 0.93 and a minimum half an orbit later. No other periodic variability was found in the light curve data. We also extracted spectra in bins spanning 0.1 in orbital phase; these show substantial variation in the profile shapes and velocity shifts of the emission lines during an orbital cycle of DW UMa. Finally, we discuss possible physical models that can qualitatively account for the observed far-ultraviolet behavior of DW UMa, in the context of recent observational evidence for the presence of a self-occulting disk in DW UMa and the possibility that the SW Sex stars may be the intermediate polars with the highest mass transfer rates and/or weakest magnetic fields.

Performance deficits in a water maze: Effect of REM sleep deprivation or cold stress?

description: The current study aims to determine the relation between memory consolidation and rapid eye movement (REM) sleep by measuring performance deficits in a behavioral task after periods of sleep deprivation. As in many prior studies, REM sleep deprivation is to be arranged by placing rats on a small platform surrounded by water. This relatively simple procedure for inducing REM sleep deprivation has been described previously as the "flower pot" technique. By using this technique, rats entering sleep lose muscle tone and fall into the water thereby preventing REM sleep. However, since no previous attempts have been made to heat the water used in the flower pot technique, animals have necessarily been exposed to cold stress as well as sleep deprivation. Therefore, a second goal of this work is to examine whether any previously observed deficits on spatial memory tasks are truly the result of REM sleep deprivation instead of the product of cold stress induced during prolonged exposures to the cool water used in the sleep deprivation apparatus.

description: We study the accuracy with which weak lensing measurements could be made from a future space-based survey, predicting the subsequent precisions of 3-dimensional dark matter maps, projected 2-dimensional dark matter maps, and mass-selected cluster catalogues. As a baseline, we use the instrumental specifications of the Supernova/Acceleration Probe (SNAP) satellite. We first compute its sensitivity to weak lensing shear as a function of survey depth. Our predictions are based on detailed image simulations created using `shapelets', a complete and orthogonal parameterization of galaxy morphologies. We incorporate a realistic redshift distribution of source galaxies, and calculate the average precision of photometric redshift recovery using the SNAP filter set to be Delta z=0.034. The high density of background galaxies resolved in a wide space-based survey allows projected dark matter maps with a rms sensitivity of 3% shear in 1 square arcminute cells. This will be further improved using a proposed deep space-based survey, which will be able to detect isolated clusters using a 3D lensing inversion techniques with a 1 sigma mass sensitivity of approximately 10^13 solar masses at z~0.25. Weak lensing measurements from space will thus be able to capture non-Gaussian features arising from gravitational instability and map out dark matter in the universe with unprecedented resolution.

description: The Economic Research Service (ERS) published bST and the Dairy Industry: A National, Regional, and Farm-level Analysis in 1987. In 1989, ERS was requested to update and extend the study. The following findings of the earlier study remain valid: effects of bST on the dairy industry would not be as dramatic as originally projected; changes underway in the industry would be reinforced but not significantly changed with bST adoption; and industry effects of bST ultimately depend on the flexibility of the dairy price support program. Current international dairy market conditions are different than those of the 1987 study. Attitudes toward bST in other milkproducing countries have been generally unfavorable. Liberalized agricultural trade could lead to greater participation by the United States in international dairy trade but whether international buyers would purchase products containing milk from bST-treated animals is unknown.

description: This study examines the behavior of public agents creating and administering policies to transfer rent among domestic economic interest groups. After a brief survey of endogenous tariff theory and attempts to apply it to agricultural policy, the study develops a model synthesizing the economic theory of regulation and the theory of optimal taxation to generate hypotheses regarding the relation between economic development and the bias of agricultural and food policy. The analysis sustains the proposition that the bias of agricultural policy shifts from pro-consumer to pro-producer and from fiscal surplus to fiscal deficit with the industrialization and diversification of the national economy. The model also provides predictions of the onset of agricultural protectionism in middle-income countries.

description: Over the past 25 years, growth in agricultural imports in Japan, Korea, Taiwan, and Hong Kong has been significant. Growth in imports of high-value products (HVP's) generally exceeded growth in imports of low-value products (LVP's) and often exceeded growth in gross domestic product. The United States was the leading provider of both HVP's and LVP's to those East Asian countries between 1962 and 1986. The bulk of the East Asian countries' imports from the United States have been LVP's, although the share of HVP's in total imports has been rising. The East Asian countries will remain important markets for agricultural imports in the nineties as a result of continued strong economic growth and trade liberalization, both of which will especially benefit HVP imports.
Quantum circuit-like learning: A fast and scalable classical machine-learning algorithm with similar performance to quantum circuit learning

description: The application of near-term quantum devices to machine learning (ML) has attracted much attention. In one such attempt, Mitarai et al. (2018) proposed a framework to use a quantum circuit for supervised ML tasks, which is called quantum circuit learning (QCL). Due to the use of a quantum circuit, QCL can employ an exponentially high-dimensional Hilbert space as its feature space. However, its efficiency compared to classical algorithms remains unexplored. In this study, using a statistical technique called count sketch, we propose a classical ML algorithm that uses the same Hilbert space. In numerical simulations, our proposed algorithm demonstrates similar performance to QCL for several ML tasks. This provides a new perspective with which to consider the computational and memory efficiency of quantum ML algorithms.

Evaluative concerns perfectionism: Perfectionism cognitions and neuroticism
Creators: name: Klein, Stephanie M.
Publisher: name: American University
Year: 2023

description: The current study addressed two major questions. First, the relationship between evaluative concerns perfectionism and coping strategies and positive and negative affect was explored; whether perfectionism cognitions mediate these relationships was also addressed. The second question assessed whether evaluative concerns perfectionism added to the prediction of emotional reactivity and negative affect when controlling for neuroticism. It was expected that perfectionism cognitions (a type of automatic thought process) would mediate the relationship between evaluative concerns perfectionism and coping strategies (in particular, distraction and emotion expression) and negative affect. It was also expected that evaluative concerns perfectionism would significantly predict perfectionism cognitions when controlling for neuroticism. One hundred twenty-one male and female participants were drawn from a mid-sized private university, and completed initial measures of perfectionism and neuroticism. Using a web-based survey, participants then completed twice daily assessments of perfectionism cognitions, coping, and positive and negative affect. Evaluative concerns perfectionism was found to be related to seeking reassurance, emotion expression, distraction, and negative affect. Further, perfectionism cognitions were found to mediate the relationship between evaluative concerns perfectionism and seeking reassurance, and evaluative concerns perfectionism and emotion expression. Perfectionism cognitions also partially mediated the relationship between evaluative concerns perfectionism and negative affect. However, evaluative concerns perfectionism, but not perfectionism cognitions, had a direct effect on the use of distraction. Evaluative concerns perfectionism and neuroticism were not significantly related to emotional reactivity; however, evaluative concerns perfectionism continued to have a direct impact on negative affect when controlling for neuroticism. The present study provides support for the incremental predictive validity of evaluative concerns perfectionism above neuroticism, and provides evidence for perfectionism cognitions as a mediator of daily stress and coping.
Exact joint density-current probability function for the asymmetric exclusion process

description: We study the asymmetric exclusion process with open boundaries and derive the exact form of the joint probability function for the occupation number and the current through the system. We further consider the thermodynamic limit, showing that the resulting distribution is non-Gaussian and that the density fluctuations have a discontinuity at the continuous phase transition, while the current fluctuations are continuous. The derivations are performed by using the standard operator algebraic approach, and by the introduction of new operators satisfying a modified version of the original algebra.
