description: The objective of the study is to identify the productive outcomes of agricultural rehabilitation program (ARP) at household level in Bangladesh. The study used latest Household Income and Expenditure Survey, 2010 and have applied PSM approach to analyse the impacts. The study has chosen 4286 households to include in probit model as control group from the households other than the treated group of 446 households. Propensity scores ranged from approximately zero to one with a mean of 0.102. Various indicators such as labor allocation, income generating activities, investment and shock`s coping strategies etc. were chosen to identify the productive outcomes. The ATE on the treated was significant for income generating activities (farm and non-farm), labor allocation (farm and non-farm, self-employment) and investment (agricultural assets, inputs). The farm activities increased by 0.40 units but non-farm activities declined by 0.73 units per household due to agriculture rehabilitation program. One of the areas of reduction of labor unit is day laborer in non-farm sector - moved from non-farm to on-farm activities. The results suggest that ARP is a promising means of safety net for the marginal and small farmers in Bangladesh. This type of safety net could contribute more to productive outcomes.

description: Cognitive biases are widespread in humans and animals alike, and can sometimes be reinforced by social interactions. One prime bias in judgment and decision-making is the human tendency to underestimate large quantities. Previous research on social influence in estimation tasks has generally focused on the impact of single estimates on individual and collective accuracy, showing that randomly sharing estimates does not reduce the underestimation bias. Here, we test a method of social information sharing that exploits the known relationship between the true value and the level of underestimation, and study if it can counteract the underestimation bias. We performed estimation experiments in which participants had to estimate a series of quantities twice, before and after receiving estimates from one or several group members. Our purpose was threefold: to study (i) whether restructuring the sharing of social information can reduce the underestimation bias, (ii) how the number of estimates received affects the sensitivity to social influence and estimation accuracy, and (iii) the mechanisms underlying the integration of multiple estimates. Our restructuring of social interactions successfully countered the underestimation bias. Moreover, we find that sharing more than one estimate also reduces the underestimation bias. Underlying our results are a human tendency to herd, to trust larger estimates than one's own more than smaller estimates, and to follow disparate social information less. Using a computational modelling approach, we demonstrate that these effects are indeed key to explain the experimental results. Overall, our results show that existing knowledge on biases can be used to dampen their negative effects and boost judgment accuracy, paving the way for combating other cognitive biases threatening collective systems.

description: Agriculture is a major source of livelihood and the main engine of economic growth in developing countries therefore the development of agricultural production is a public priority but most farmers are poor, hence there is gap in cash resources which blocks the adoption of new technologies innovation and credit is needed to fill the gap in Nigeria .Therefore, this study was carried out to assess anchor borrower s programme a central bank of Nigeria's intervention on rice production in Kwara State, Nigeria. Data for the data were sourced primarily from rice producers with the aid of a structured questionnaire. The findings reveal that 88.1% of the beneficiaries breached the agreement and refuse to deliver their produce to the Anchor Borrowers Programme due some reasons and their average estimated yield per hectare of paddy rice for all beneficiaries was 3.94 metric tons per hectare. Anchor Borrowers Programme had a positive effect on the income of the beneficiaries. Therefore the study recommended that the governments must intervene with subsidized lending (seeking no profit, amortizing high transaction costs, spreading the risk on a national basis),since most borrowers in rural areas are small farmers (i.e. poor), low cost credit responds to poverty alleviation considerations .

description: We establish a kind of "degree zero Freudenthal Gm-suspension theorem" in motivic homotopy theory. From this we deduce results about the conservativity of the P^1-stabilization functor. In order to establish these results, we show how to compute certain pullbacks in the cohomology of a strictly homotopy invariant sheaf in terms of the Rost--Schmid complex. This establishes the main conjecture of [BY18], which easily implies the aforementioned results.

description: This paper presents a flexible conceptual and methodological framework to model the dynamics of agricultural transition in the increasingly complex rural-urban interfaces of large cities. Our empirical analysis is based on data of a household survey conducted in the rural-urban interface of Bangalore, India. In our analysis we follow a polycentric perspective of urbanization introducing a two-dimensional variable measuring the effect of urbanization. Furthermore, we accommodate high input and crop diversity by applying a Structured Additive Regression (STAR) model. Our results show that satellite towns and road infrastructure are the main channels of urbanization to accelerate agricultural transition. The access to satellite towns seems to be even more important for smallholders to modernize their management systems than the access to the actual main city of Bangalore. Finally, our study implies that more flexible models are necessary to understand the dynamics of agricultural transition in the surroundings of fast-growing large towns, the kind of town expected to be dominating the urbanization trend in the coming decades.

Three essays on the indirect impacts of conditional cash transfer programs in Mexico and Nicaragua
Creators: name: Todd, Jessica Erin
Publisher: name: American University
Year: 2023

description: This dissertation contributes to the evaluation of Conditional Cash Transfer (CCT) programs by estimating indirect impacts of the Oportunidades and RPS programs in rural Mexico and Nicaragua, respectively, using experimentally designed data. The first essay estimates the impact of early nutrition intervention in the Oportunidades program on the probability of enrolling in primary school on time. Identification is achieved through a cross-sectional double difference estimator on observations from two cohorts of children. Although the results are not strongly significant, they do indicate that early nutritional interventions can have a positive impact on school outcomes and that care giver characteristics affect the magnitude of the impact. The results also highlight that a first difference estimate of the impact would be downwardly biased by unobserved differences in characteristics. The second essay examines the impact of the RPS program on an intermediate fertility outcome, birth spacing, using a stratified Cox proportional hazard model. Birth histories of female household heads and spouses are constructed from household roster information, and to deal with autocorrelation, the data are stratified by parity (the number of live births). The results indicate that the RPS program decreased the hazard of a birth, which resulted in an increase in the space between births of between 6 to 8 months. Further research is required to determine whether the impacts will persist in the long-run. The final essay explores whether the Oportunidades program relaxes liquidity constraints and can lead to increased agricultural production; this is explored by estimating the impact of the program on consumption of food from own production as well as on land use, livestock ownership and spending on agricultural crop production. Impacts estimated using first difference estimators are compared to those from weighted estimators in which the weights are constructed from propensity scores. The program is found to increase the value and variety of food consumed from own production; no differences in the two estimators are observed. In addition, small positive impacts on land use, livestock ownership and crop spending are observed. The implication of these findings is that part of the cash received is invested in agricultural production.

description: We study an example of higher-order field-theoretic model with an eighth-degree polynomial potential -- the $φ^8$ model. We show that for some certain ratios of constants of the potential, the problem of finding kink-type solutions in $(1+1)$-dimensional space-time reduces to solving algebraic equations. For two different ratios of the constants, which determine positions of the vacua, we obtained explicit formulas for kinks in all topological sectors. The properties of the obtained kinks are also studied -- their masses are calculated, and the excitation spectra which could be responsible for the appearance of resonance phenomena in kink-antikink scattering are found.

description: This paper explores diversification for land and labor by smallholder farmers in Southwest China in response to the rubber price declines. Panel data of some 600 smallholder rubber farmers in Xishuangbanna, Southwest China in 2012 and 2014 is employed. Livelihood diversification is expressed by calculating Shannon for land and labor. We developed Tobit panel models to identify the determinants of diversification, and OLS and Quantile regression models to analyze the correlation between diversification and income. We find that (i) household incomes are more diverse after the decline of rubber prices; (ii) diversification contributes to smoothing household income; (iii) households with higher incomes are more likely to diversify their portfolios of crop and employment; (iv) diversification contributes to decrease of income inequality. We conclude that a more diversification in labor is more effective in mitigating negative effects of shocks from rubber price decline. Land diversification is likely to be a more effective ex-ante shock alleviation strategy. Acknowledgement :

description: The X-ray source 1E 1207.4-5209 is a compact central object in the G296.5+10.0 supernova remnant. Its spin period of 424 ms, discovered with the Chandra X-ray Observatory, suggests that it is a neutron star. The X-ray spectrum of this radio-quiet pulsar shows at least two absorption lines, first spectral features discovered in radiation from an isolated neutron star. Here we report the results of timing analysis of Chandra and XMM-Newton observations of this source showing a non-monotonous behavior of its period. We discuss three hypotheses which may explain the observational result. The first one assumes that 1E 1207.$-5209 is a glitching pulsar, with frequency jumps of Δf > 5 \muHz occurring every 1-2 years. The second hypothesis explains the deviations from a steady spin-down as due to accretion, with accretion rate varying from \sim 10^{13} to >10^{16} g s^{-1}, from a disk possibly formed from ejecta produced in the supernova explosion. Finally, the period variations could be explained assuming that the pulsar is in a wide binary system with a long period, P_orb \sim 0.2-6 yr, and a low-mass companion, M_2 < 0.3 M_\odot.

Do United States multinationals engage in sequential choice? Evidence from new manufacturing operations in Europe and Asia-Pacific

Publisher: name: American University
Year: 2023

description: Despite an extensive literature on the determinants of the foreign location choices by multinational companies, researchers have only recently begun to systematically examine how these companies form their location consideration sets. When considering new foreign locations, do firms evaluate the attributes of the alternatives at the national level, the sub-national regional level, at some other level of geographical aggregation, or using some combination of these? This study employs discrete choice models to examine how U.S. multinational companies form their location consideration sets and to identify some of the relevant location attributes. The data set covers new manufacturing investments by U.S. companies in selected countries in Europe and Asia-Pacific over the period 1989-2003. The results indicate that U.S. firms tend to employ a sequential, or hierarchical, choice process in which a host country is first chosen based on one set of attributes and then a region within that country is chosen based on another set of attributes. Location attributes related to industrial agglomeration (such as the proximity to customers, suppliers, workers with the necessary skills, and transportation infrastructure) appear to dominate location attributes related to factor prices (such as the availability of cheap land and low-wage labor).

description: Cosmic strings arising from breaking of the $U(1)_{B-L}$ gauge symmetry that occurs in a wide variety of unified models can carry zero modes of heavy Majorana neutrinos. Decaying and/or repeatedly self-interacting closed loops of these ``$B-L$'' cosmic strings can be a non-thermal source of heavy right-handed Majorana neutrinos whose decay can contribute to the observed baryon asymmetry of the Universe (BAU) via the leptogenesis route. The $B-L$ cosmic strings are expected in GUT models such as SO(10), where they can be formed at an intermediate stage of symmetry breaking well below the GUT scale $\sim 10^{16}$ GeV; such light strings are not excluded by the CMB anisotropy data and may well exist. We estimate the contribution of $B-L$ cosmic string loops to the baryon-to-photon ratio of the Universe in the light of current knowledge on neutrino masses and mixings implied by atmospheric and solar neutrino measurements. We find that $B-L$ cosmic string loops can contribute significantly to the BAU for $U(1)_{B-L}$ symmetry breaking scale $η_{B-L}\gsim 1.7\times 10^{11}\gev$. At the same time, in order for the contribution of decaying $B-L$ cosmic string loops not to exceed the observed baryon-to-photon ratio inferred from the recent WMAP results, the lightest heavy right-handed Majorana neutrino mass $M_1$ must satisfy the constraint $M_1 \leq 2.4 \times 10^{12}(η_{B-L}/10^{13}\gev)^{1/2}\gev$. This may have interesting implications for the associated Yukawa couplings in the heavy neutrino sector and consequently for the light neutrino masses generated through see-saw mechanism.

description: During the last several years, a series of important policy changes affecting genetic resource conservation, use, and exchange have entered into force. These policy changes will likely affect investment choices made by the international research-for-development community - choices that influence scientific collaboration and cooperation nationally, regionally and internationally. Specifically, these policy changes may introduce new institutional constraints on the use of genetic resources, with potentially long-lasting influence on research priority-setting and collaboration strategies. This paper provides a novel characterization of the changing landscape governing international germplasm exchanges. Emphasis is placed on culling evidence from historical trends, networks, and econometric analysis to better understand how national regulatory changes associated with the Convention on Biological Diversity (CBD) of 1993 and the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) of 2004 affected the movement of genetic resources and lessons to be drawn to understand the potential effects of the Nagoya Protocol which entered into force beginning 2014.

description: The increasing numbers of Mexican heritage individuals residing in the U.S. combined with the educational attainment disparity between Mexican heritage and White individuals illustrate a need for research on factors associated with the high educational attainment of some immigrant and first-generation students of Mexican descent. Using one hundred and fifteen (115) autobiographical term papers written by Mexican heritage students enrolled at the University of California at Los Angeles (UCLA), thirty-three (33) Student interviews, and eight (8) family interviews as data sources, there were seven themes that emerged from this qualitative study. These include evidence of (1) Assimilation; (2) Acculturation; (3) Social capital; (4) Resilience; (5) Exposure to majority White schools/communities; (6) Exposure to minority schools/communities; and (7) A willingness to honor parental struggle and sacrifice with academic achievement---Ganas. The implications of these findings and recommendations for further research are discussed.

description: Bars in galaxies are mainly supported by particles trapped around closed periodic orbits. These orbits respond to the bar's forcing frequency only and lack free oscillations. We show that a similar situation takes place in double bars: particles get trapped around orbits which only respond to the forcing from the two bars and lack free oscillations. We find that writing the successive positions of a particle on such an orbit every time the bars align generates a closed curve, which we call a loop. Loops allow us to verify consistency of the potential. As maps of doubly periodic orbits, loops can be used to search the phase-space in double bars in order to determine the fraction occupied by ordered motions.

description: We present a new mechanism for thermally produced dark matter, based on a semi-annihilation-like process, $χ+ χ+\text{SM} \rightarrow χ+ \text{SM}$, with intriguing consequences for the properties of dark matter. First, its mass is low, $\lesssim 1$ GeV (but $\gtrsim 5$ keV to avoid structure-formation constraints). Second, it is strongly interacting, leading to kinetic equilibrium between the dark and visible sectors, avoiding the structure-formation problems of $χ+ χ+ χ\rightarrow χ+ χ$ models. Third, in the $3 \rightarrow 2$ process, one dark matter particle is consumed, giving the standard-model particle a monoenergetic recoil. We show that this new scenario is presently allowed, which is surprising (perhaps a "minor miracle"). However, it can be systematically tested by novel analyses in present and near-term experiments. In particular, the Co-SIMP model for thermal-relic dark matter can explain the XENON1T excess.

description: This report presents State-level corn production cost and return estimates for 1986-88. Corn is the leading U.S. grain commodity for total value and volume of production. Total corn production decreased during 1986-88, resulting in an 80-percent increase in corn prices over the 3-year period. Even with the decrease in production, total value of production was over $11 billion, representing about 40 percent of the total value of all grain crops sold and approximately 20 percent of the total value of production of all harvested cropland. Per-acre costs, per-bushel costs, and corn yields varied significantly among years and among regions and States within a given year.

description: First, we consider the problem of hedging in complete binomial models. Using the discrete-time Föllmer-Schweizer decomposition, we demonstrate the equivalence of the backward induction and sequential regression approaches. Second, in incomplete trinomial models, we examine the extension of the sequential regression approach for approximation of contingent claims. Then, on a finite probability space, we investigate stability of the discrete-time Föllmer-Schweizer decomposition with respect to perturbations of the stock price dynamics and, finally, perform its asymptotic analysis under simultaneous perturbations of the drift and volatility of the underlying discounted stock price process, where we prove stability and obtain explicit formulas for the leading order correction terms.

description: This report presents State-level barley production cost and return estimates for 1986-88. Barley ranks sixth among U.S. grain commodities in total planted acreage. Per-planted-acre yield of barley in 1987, at 47.9 bushels, was average for barley during the 1980's. Barley production was highly localized in 1987, with 60 percent of national production occurring in the Northern Plains region, while 20 percent was produced in the Northwest region. Per-acre costs among farmers are highly variable due to differences in production practices, inputs, and type and size of machinery use. Barley yields and per-bushel costs varied significantly among years and among regions and States within a given year.
Vector opinion dynamics in a model for social influence

description: We present numerical simulations of a model of social influence, where the opinion of each agent is represented by a binary vector. Agents adjust their opinions as a result of random encounters, whenever the difference between opinions is below a given threshold. Evolution leads to a steady state, which highly depends on the threshold and a convergence parameter of the model. We analyze the transition between clustered and homogeneous steady states. Results of the cases of complete mixing and small-world networks are compared.

Factors that contribute to the academic success of immigrant and first-generation UCLA students of Mexican heritage
Creators: name: Easley, Nate
Publisher: name: American University

description: The increasing numbers of Mexican heritage individuals residing in the U.S. combined with the educational attainment disparity between Mexican heritage and White individuals illustrate a need for research on factors associated with the high educational attainment of some immigrant and first-generation students of Mexican descent. Using one hundred and fifteen (115) autobiographical term papers written by Mexican heritage students enrolled at the University of California at Los Angeles (UCLA), thirty-three (33) Student interviews, and eight (8) family interviews as data sources, there were seven themes that emerged from this qualitative study. These include evidence of (1) Assimilation; (2) Acculturation; (3) Social capital; (4) Resilience; (5) Exposure to majority White schools/communities; (6) Exposure to minority schools/communities; and (7) A willingness to honor parental struggle and sacrifice with academic achievement---Ganas. The implications of these findings and recommendations for further research are discussed.

Helping Those Who Venture: Iowa's Rural Economic Development Measures

Subjects: subject: Agricultural and Food Policy

description: Iowa's State government has assumed a major role in rural economic development. Eighty-two rural development measures have been identified by State agency heads and State budget officers. Together, these measures encompass a quarter of the State budget. A majority of the measures are aimed at community and business development. In recent years, State and local economic development efforts have increased in response to a declining Federal effort. Given limited State resources, the result has been a neglect of communities that have not been as aggressive and consistent in seeking economic development.
Relationship between community events and activities on campus and student stress

description: In our present study, we investigated whether frequency of engagement in community events and activities on the UBC campus influence student’s stress levels on campus. In order to find the correlation between year-level & stress level of students with frequency of engagement in annual campus events and activities, we conducted a self-report online survey where participants were asked to provide answers to the questions regarding their perceived stress level and frequency of engagement with community events on campus. We have found that there is no correlation between the year-level & stress level with the frequency of engagement. We have obtained the result by calculating the Pearson’s correlation coefficient and the value r=-0.0011 indicated that there is no significant correlation. Moreover, the means of stress level for Freshmen and Seniors were relatively similar (M=23.21 for freshmen and M=22.72 for seniors) indicating that perceived stress plateaus throughout university experience regardless of their engagement in community events.

What Can We Learn by Combining the Skew Spectrum and the Power Spectrum?

description: Clustering of the large scale structure provides complementary information to the measurements of the cosmic microwave background anisotropies through power spectrum and bispectrum of density perturbations. Extracting the bispectrum information, however, is more challenging than it is from the power spectrum due to the complex models and the computational cost to measure the signal and its covariance. To overcome these problems, we adopt a proxy statistic, skew spectrum which is a cross-spectrum of the density field and its quadratic field. By applying a large smoothing filter to the density field, we show the theory fits the simulations very well. With the spectra and their full covariance estimated from $N$-body simulations as our "mock" Universe, we perform a global fits for the cosmological parameters. The results show that adding skew spectrum to power spectrum the $1σ$ marginalized errors for parameters $ b_1^2A_s, n_s$ and $f_{\rm NL}^{\rm loc}$ are reduced by $31\%, 22\%, 44\%$, respectively. This is the answer to the question posed in the title and indicates that the skew spectrum will be a fast and effective method to access complementary information to that enclosed in the power spectrum measurements, especially for the forthcoming generation of wide-field galaxy surveys.

description: The number of devices in the Internet of Things (IoT) immensely grew in recent years. A frequent challenge in the assurance of the dependability of IoT systems is that components of the system appear as a black box. This paper presents a semi-automatic testing methodology for black-box systems that combines automata learning and fuzz testing. Our testing technique uses stateful fuzzing based on a model that is automatically inferred by automata learning. Applying this technique, we can simultaneously test multiple implementations for unexpected behavior and possible security vulnerabilities.
 We show the effectiveness of our learning-based fuzzing technique in a case study on the MQTT protocol. MQTT is a widely used publish/subscribe protocol in the IoT. Our case study reveals several inconsistencies between five different MQTT brokers. The found inconsistencies expose possible security vulnerabilities and violations of the MQTT specification.

description: This paper documents the basic Computable General Equilibrium (CGE) model of the U.S. economy developed at the Economic Research Service (ERS), USDA. The paper both describes the model equations in detail and how the model is "benchmarked" to a base data set. The paper also lists the computer program used to implement the model. The objective of the CGE work program at ERS is to provide a multisectoral framework for analyzing the effect of changes in agricultural policies and exogenous shocks on the farm sector, on the rural economy, on related nonagricultural sectors, and on the rest of the economy. The basic model has provided a starting point for a variety of extensions and applications exploring a number of policy issues. To date, work has largely focused on issues of agricultural trade policy and the effect of alternative domestic policies.

Bell's inequality and the coincidence-time loophole
Creators: name: Larsson, Jan-Åke
name: Gill, Richard
Publisher: name: arXiv
Year: 2003
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: This paper analyzes effects of time-dependence in the Bell inequality. A generalized inequality is derived for the case when coincidence and non-coincidence [and hence whether or not a pair contributes to the actual data] is controlled by timing that depends on the detector settings. Needless to say, this inequality is violated by quantum mechanics and could be violated by experimental data provided that the loss of measurement pairs through failure of coincidence is small enough, but the quantitative bound is more restrictive in this case than in the previously analyzed "efficiency loophole."
