description: Biographical data gathered in surveys are often stored in spell format, allowing for overlaps between spell states. On the one hand, these kind of data provide useful information for researchers. On the other hand, the data structure is often complex and not easy to handle. The newspell program offers a solution to the problem of spell-data management with three important features. First, it can rank spells and cut off overlaps according to the rank order. Second, newspell can combine overlapping parts of spells into new categories of spells, generating entirely new states. Third, it can detect gaps in the spell data that are not yet coded. It also includes subcommands for the management of complex spell data. Spell states can be merged and filled in with information from adjacent spells, and the data can be transformed to long or wide format. The command can be used to clean data, to combine two spell-data sources that have information on different kinds of states, or to deal with spell data that are complex by survey design. newspell is useful for users who are not familiar with complex spell data and have little experience in Stata programming or data management. For experienced users, newspell saves a lot of time and coding work.

RELATIONSHIP BETWEEN NIGERIAN STUDENTS' VALUES AND EDUCATIONAL GOALS IN SCIENCE AND NON-SCIENCE MAJORS WITHIN THE CONSORTIUM OF UNIVERSITIES OF WASHINGTON, D.C. METROPOLITAN AREA
Creators: name: Udoibe, Ndarake David
Publisher: name: American University
Year: 2023

description: This study was conducted to determine any relationship which may exist between Nigerian students' values and educational goals in science and non-science majors within the Consortium of Universities of Washington, D.C. Metropolitan area. Methodology. Nigerian Students' Values and Educational Goals Survey was administered to 485 Nigerian undergraduates in six institutions within the Consortium during the fall semester of 1982. A parallel survey was conducted among seventy randomly selected American undergraduate students at The American University, Washington, D.C. Sample populations for both groups consisted of all four classes of undergraduate students. The Nigerian student sample consisted of 166 Science and Non-Science majors drawn randomly from all survey respondents in the six institutions within the Consortium. The American students' sample consisted of fifty-six students out of seventy randomly selected domestic students. Survey responses were coded and analyzed through the application of percentage, frequency distribution, rank-order, Spearman rank correlation coefficient, and Chi Square test. All hypotheses were tested at 0.01 level of significance. Findings and Conclusions. All Nigerian students responding endorsed (1) being Ambitious, Honest and Intellectual as their principal instrumental values, (2) Vocational Training, Basic General Education, and Knowledge in Community Problems as the principal educational goals, and (3) Economic Security, Career, and Personal Identity as their principal life satisfactions. There was no sufficient evidence to conclude that Nigerian Science and Non-Science majors differed significantly on values, educational goals and life satisfactions. A considerable agreement was found for both groups in all three categories (values, educational goals and life satisfactions). Significant differences existed between Nigerian Freshmen and Seniors on instrumental values, educational goals and life satisfactions. Freshmen were more concerned than Seniors with Cleanliness, Honesty, Obedience, Politeness, Knowledge in Community Problems, Religion and Home Improvement. They were less concerned than Seniors with being Broadminded, Imaginative and Intellectual. They assigned lesser priorities than Seniors to Basic General Education and Art/Intellectual activities. The investigator postulated that these differences might have occurred because of some aspects of college life. American students like their Nigerian counterparts valued Economic Security, Career, and Personal Identity as their primary sources of life satisfactions. However, Career and Family were more popular among Domestic students.

description: Star clusters are ideal platforms for categorising X-ray emitting stars and to study X-ray emission as a function of stellar age and activity. We present a comprehensive study of an open star cluster, NGC2527, by combining data from XMM-UVOT-Gaia. Cluster membership of stars and their photometry are taken from Gaia and cross-matched with XMM and UVOT detections. We estimate the age of NGC2527 as ~630 Myr, reddening as E(B-V)=0.13 mag, and a distance of 642+/-30 pc using PARSEC isochrones. We detect 5 sub-subgiants and 5 bandgap stars, which defy single star evolution. We estimate the temperature, mass, radius, and luminosity of 53 single stars and 10 potential binary stars using a python code which fits single and composite Kurucz spectra to broad-band Spectral Energy Distribution. Among the 12 X-ray emitting members, we find 5 are potential RS CVn type binaries, 2 are potential FK Comae type of RGB stars, and 5 are main sequence (MS) stars with high coronal activity. Members with strong UV emission comprise of 1 RGB star, and several MS stars with UV excess suggestive of chromospheric activity. Based on comparison with other clusters, we tentatively suggest that X-ray luminosity of both RS CVn and contact binaries increases with age suggesting more active binaries are present in older clusters as compared to younger clusters. This study suggests the possible presence of W UMa and FK Comae type stars in younger (age~630 Myr) clusters.

description: We address the problem of finding optimal CPTP (completely positive, trace preserving) maps between a set of binary pure states and another set of binary generic mixed state in a two dimensional space. The necessary and sufficient conditions for the existence of such CPTP maps can be discussed within a simple geometrical picture. We exploit this analysis to show the existence of an optimal quantum repeater which is superior to the known repeating strategies for a set of coherent states sent through a lossy quantum channel. We also show that the geometrical formulation of the CPTP mapping conditions can be a simpler method to derive a state-dependent quantum (anti) cloning machine than the study so far based on the explicit solution of several constraints imposed by unitarity in an extended Hilbert space.

METROPOLITAN REGIONAL COUNCIL PERFORMANCE IN HOUSING ASSISTANCE POLICY: A TEST OF TWO MODELS OF ORGANIZATIONAL EFFECTIVENESS
Creators: name: Wrightson, Margaret Tucker
Publisher: name: American University
Year: 2023

description: The purpose of this dissertation is to evaluate which of two completing models--one from political science, the other from public administration--more effectively predicts regional council performance redistributing multifamily housing assistance in metropolitan areas since the passage of the Housing and Community Development Act of 1974. The Act sets forth a national policy of deconcentrating assisted housing and provides regional councils new opportunities to influence metropolitan allocation policy in that direction. Political science and public administration literature offer contrasting hypotheses about council performance. According to the latter, stronger organizations will be more effective. Political science does not discount the value of organizational strength, but predicts that without political power councils will be unable to perform effectively. A sample of thirty-six councils was surveyed about their organizational characteristics and involvement in housing assistance. Initial cross tabulations of twenty-two organizational variables and redistribution produced the following finding. Only council use of two nationally inspired intergovernmental policy instruments was related to redistribution. Council use was voluntary, however. Thus, to extend the analysis the effect of a third variable was tested. It was defined as "regional predisposition to accept the redistribution policy" and was measured by the following proxies: regional liberalism, economic balance, and racial homogeneity. Tests showed that while the relationship between council use of the instruments and redistribution was not spurious, it was contingent on regional predispositions. Only in the regions favoring the policy were councils effective. This suggests that councils are unlikely to make a difference in the critical issues troubling urban politics unless national, state, and local governments cede to them the requisite political power. Without it, they are likely to continue to reflect the policy positions of the governments upon whom they depend.

description: Recent trends in high-performance computing and deep learning have led to the proliferation of studies on large-scale deep neural network training. However, the frequent communication requirements among computation nodes drastically slows the overall training speeds, which causes bottlenecks in distributed training, particularly in clusters with limited network bandwidths. To mitigate the drawbacks of distributed communications, researchers have proposed various optimization strategies. In this paper, we provide a comprehensive survey of communication strategies from both an algorithm viewpoint and a computer network perspective. Algorithm optimizations focus on reducing the communication volumes used in distributed training, while network optimizations focus on accelerating the communications between distributed devices. At the algorithm level, we describe how to reduce the number of communication rounds and transmitted bits per round. In addition, we elucidate how to overlap computation and communication. At the network level, we discuss the effects caused by network infrastructures, including logical communication schemes and network protocols. Finally, we extrapolate the potential future challenges and new research directions to accelerate communications for distributed deep neural network training.

On the basis of the equations of fluid mechanics we present a quantitative derivation of the "maximum drag reduction (MDR) asymptote" which is the maximum drag reduction attained by polymers. Based on Newtonian information only we prove the existence of drag reduction, and with one experimental parameter we reach a quantitative agreement with the experimental measurements.

THE JOHN ADAMS PRESIDENCY: WAR CRISIS LEADERSHIP IN THE EARLY REPUBLIC
Creators: name: Holder, Jean S.
Publisher: name: American University
Year: 2023

description: In 1797 citizens of the new American republic looked to the first transition of government with foreboding, questioning the ability of any successor to maintain the public confidence that George Washington had enjoyed. Following the nation's greatest hero in office at a time of grave international crisis, as France began undeclared naval war on the United States, John Adams faced unique problems as the second American president. Elected by a narrow margin, having little patronage to dispense, opposed by a small but powerful clique within his own party, Adams served with an inherited cabinet whose three principal members worked to advance the interests of the president's intra-party adversary, Alexander Hamilton. Although bereft of even the minimal resources available to other early presidents for advancing the executive interest by bargaining and persuasion, Adams conducted a successful administration, an achievement that has been overlooked or downplayed by historians because of the second president's failure to win reelection. In his one term of office Adams established a Navy Department and rapidly expanded the country's embryonic navy. He implemented major foreign policy decisions, securing approachment with France through two diplomatic initiatives, the second effort a bold move made in defiance of Federalist party leaders loyal to Hamilton. By restoring balance to foreign policy and checking Hamilton's attempts to use the army as a vehicle of personal and national aggrandizement, Adams reassured Republican adversaries, defusing a conflict between political parties that held the potential for civil disruption. He left the nation at peace, its defenses secure, internal tranquility restored, thereby paving the way for a successful first transition of party government. Because of Adams's extremely limited resources as president, his administration provides a singular case study for evaluating two opposing interpretations of the basis of presidential power: constitutional authority vs. bargaining and persuasion, advanced by Richard M. Pious, The American Presidency (New York, 1979) and Richard Neustadt, Presidential Power: The Politics of Leadership (New York: 1960), respectively. Adams demonstrated that in the early period of the nation's history a resourceful chief executive could function effectively in office with little more than his constitutional authority to sustain him.

description: Jacob Bekenstein's identification of black hole event horizon area with entropy proved to be a landmark in theoretical physics. In this paper we trace the subsequent development of the resulting generalized second law of thermodynamics (GSL), especially its extension to incorporate cosmological event horizons. In spite of the fact that cosmological horizons do not generally have well-defined thermal properties, we find that the GSL is satisfied for a wide range of models. We explore in particular the case of an asymptotically de Sitter universe filled with a gas of small black holes as a means of casting light on the relative entropic 'worth' of black hole versus cosmological horizon area. We present some numerical solutions of the generalized total entropy as a function of time for certain cosmological models, in all cases confirming the validity of the GSL.

description: Amorphous solids lack long-range order. Therefore identifying structural defects -- akin to dislocations in crystalline solids -- that carry plastic flow in these systems remains a daunting challenge. By comparing many different structural indicators in computational models of glasses, under a variety of conditions we carefully assess which of these indicators are able to robustly identify the structural defects responsible for plastic flow in amorphous solids. We further demonstrate that the density of defects changes as a function of material preparation and strain in a manner that is highly correlated with the macroscopic material response. Our work represents an important step towards predicting how and when an amorphous solid will fail from its microscopic structure.

Quantum initial value representations using approximate Bohmian trajectories

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Quantum trajectories, originating from the de Broglie-Bohm (dBB) hydrodynamic description of quantum mechanics, are used to construct time-correlation functions in an initial value representation (IVR). The formulation is fully quantum mechanical and the resulting equations for the correlation functions are similar in form to their semi-classical analogs but do not require the computation of the stability or monodromy matrix or conjugate points. We then move to a {\em local} trajectory description by evolving the cumulants of the wave function along each individual path. The resulting equations of motion are an infinite hierarchy, which we truncate at a given order. We show that time-correlation functions computed using these approximate quantum trajectories can be used to accurately compute the eigenvalue spectrum for various potential systems.

description: We present a new algorithm for determining the satisfiability of conjunctions of non-linear polynomial constraints over the reals, which can be used as a theory solver for satisfiability modulo theory (SMT) solving for non-linear real arithmetic. The algorithm is a variant of Cylindrical Algebraic Decomposition (CAD) adapted for satisfiability, where solution candidates (sample points) are constructed incrementally, either until a satisfying sample is found or sufficient samples have been sampled to conclude unsatisfiability. The choice of samples is guided by the input constraints and previous conflicts. The key idea behind our new approach is to start with a partial sample; demonstrate that it cannot be extended to a full sample; and from the reasons for that rule out a larger space around the partial sample, which build up incrementally into a cylindrical algebraic covering of the space. There are similarities with the incremental variant of CAD, the NLSAT method of Jovanovic and de Moura, and the NuCAD algorithm of Brown; but we present worked examples and experimental results on a preliminary implementation to demonstrate the differences to these, and the benefits of the new approach.
A COMPARISON OF SOCIAL AND BEHAVIORAL PROBLEMS OF ELEMENTARY AND JUNIOR HIGH SCHOOL LEARNING DISABLED CHILDREN
Creators: name: Hertz, Carole Mathers
Publisher: name: American University
Year: 2023

description: The purpose of this study was to describe and contrast the behaviors of twenty-six third grade and twenty-six seventh grade learning disabled students. The study included analyses related to length of time the student was mainstreamed in regular classes. The extent to which the subjects' behavior differs from that of their regular class peers was also measured. Subjects for the study were enrolled in grades three and seven during the school year 1981-1982. School records were studied to determine the subjects' length of time in the special class and length of time mainstreamed. Behavioral status was assessed by regular classroom teachers' rating of subjects and randomly-selected, same-sex classmates on the Peterson-Quay Behavior Problem Checklist. The differences between group means for behavior, length of time in placement and length of time mainstreamed were tested for significance using a two and three way analysis of variance. A significance level of .05 was used. Results of the analysis of contrasting 3rd and 7th grade behavior problems showed that 3rd grade LD students have a higher number of problems in Conduct, Personality and Inadequacy-Immaturity than 7th grade LD students. Both grade groups showed very few problems in the area of Socialized Delinquent or Psychotic Behavior. Testing of behavior problems based upon regular teacher ratings of LD subjects and their "regular" classroom peers, the LD subjects in both 3rd and 7th grade exhibited significantly more social and behavioral problems than their non-LD peers. Examination of the results of length of time in special class placement and length of time mainstreamed to determine the possible effect of those variables on the study subjects was inconclusive due to the statistical sameness of those variables. It can be concluded that regular education teachers perceived 3rd grade LD subjects as exhibiting more social and behavioral problems than 7th grade LD subjects and all LD subjects in both the 3rd and 7th grade as exhibiting more social and behavioral problems than their "regular" education classmates. Recommendations are made for further research and for improvements in preparation of school personnel for dealing with returning special class students.

description: Research background: A combination of technology and efficiency gains will drive future intensification programs aimed at fostering food and nutrition security in the developing world. Specifically, the adoption of improved varieties and use of quality seed alongside good agronomic practices will be critical. Purpose of the article: Given the space-time availability of technology, this study investigates how production efficiency (technical efficiency, technology gap, and meta technical efficiency) has changed over time and assesses the possibility of heterogeneous technology adoption in Ghana. Methods: The study constructs a rich nationally representative dataset of dry beans and groundnut farmers that constitutes 15 production seasons in Ghana. Using a sample of 10,518 farmers from 10,051 households, a Meta Stochastic Frontier (MSF) approach is used to access changes and determinants efficiency and technology adoption. Findings & Value added: We find that farms are operating under heterogeneous technologies along ecological lines and that the technology gap has been reducing over time. Improvements in meta technical efficiency could be driven by the gains in the technology gap ratio. Technical efficiency levels across the two legumes averaged about 61% and did not significantly improve between 1987 to 2017. The key determinants for the observed trends were farmer education, mechanization, access to agricultural extension services, and land ownership. Holding ecological technologies constant, legume farmers generally performed poorly because of technical inefficiency, implying that a general improvement in farmer managerial skills could substantially improve farm output. The study recommends policies/programs be formulated on a case-by-case basis; to ensure specificity and wider impacts, if production is to improve.

description: The purpose of this study was to describe and contrast the behaviors of twenty-six third grade and twenty-six seventh grade learning disabled students. The study included analyses related to length of time the student was mainstreamed in regular classes. The extent to which the subjects' behavior differs from that of their regular class peers was also measured. Subjects for the study were enrolled in grades three and seven during the school year 1981-1982. School records were studied to determine the subjects' length of time in the special class and length of time mainstreamed. Behavioral status was assessed by regular classroom teachers' rating of subjects and randomly-selected, same-sex classmates on the Peterson-Quay Behavior Problem Checklist. The differences between group means for behavior, length of time in placement and length of time mainstreamed were tested for significance using a two and three way analysis of variance. A significance level of .05 was used. Results of the analysis of contrasting 3rd and 7th grade behavior problems showed that 3rd grade LD students have a higher number of problems in Conduct, Personality and Inadequacy-Immaturity than 7th grade LD students. Both grade groups showed very few problems in the area of Socialized Delinquent or Psychotic Behavior. Testing of behavior problems based upon regular teacher ratings of LD subjects and their "regular" classroom peers, the LD subjects in both 3rd and 7th grade exhibited significantly more social and behavioral problems than their non-LD peers. Examination of the results of length of time in special class placement and length of time mainstreamed to determine the possible effect of those variables on the study subjects was inconclusive due to the statistical sameness of those variables. It can be concluded that regular education teachers perceived 3rd grade LD subjects as exhibiting more social and behavioral problems than 7th grade LD subjects and all LD subjects in both the 3rd and 7th grade as exhibiting more social and behavioral problems than their "regular" education classmates. Recommendations are made for further research and for improvements in preparation of school personnel for dealing with returning special class students.

description: In this paper we have investigated a bulk viscous universe in $f(R,T)$ gravity where $R$ and $T$ are the Ricci scalar and trace of energy momentum tensor respectively. We have obtained explicit solutions of field equations in modified gravity by considering the power law form of scale factor. The Hubble parameter and deceleration parameter are derived in terms of cosmic time and redshift both. We have estimated the present values of these parameters with observational Hubble data and SN Ia data sets. At 1$σ$ level, the estimated values of $q_{0}$ and $m$ are obtained as $q_{0}=-0.30 \pm 0.05$ \& $ m = 0.70 \pm 0.02 $ where $q_{0}$ is the present value of deceleration parameter and $m$ is the model parameter. The energy conditions and Om(z) analysis for the anisotropic LRS Bianchi type I model are also discussed.

description: We study the low-energy properties of a sawtooth chain with spin-1's at the bases of the triangles and spin-1/2's at the vertices of the triangles. The spins have Heisenberg antiferromagnetic interactions between nearest neighbors, with a coupling J_2 between a spin-1 and a spin-1/2, and a coupling J_1 = 1 between two spin-1's. Analysis of the exact diagonalization data for periodic chains containing up to N=12 unit cells shows that the ground state is a singlet for exchange couplings up to approximately J_2 = 3.8, whereas for larger J_2, the system exhibits a ferrimagnetic ground state characterized by a net ferromagnetic moment per unit cell of 1/2. In the region of small interactions J_2, the mixed spin sawtooth chain maps on to an effective isotropic spin model representing two weakly interacting and frustrated spin-1/2 Heisenberg chains composed of spin-1/2 sites at odd and even vertices respectively. Finally, we study the phenomenon of a macroscopic magnetization jump which occurs if a magnetic field is applied with a value close to the saturation field for J_2 = 2.

description: Property FW is a natural combinatorial weakening of Kazhdan's Property T. We prove that the group of piecewise homographic self-transformations of the real projective line, has "few" infinite subgroups with Property FW. In particular, no such subgroup is amenable or has Kazhdan's Property T. These results are extracted from a longer paper. We provide a complete proof, whose main tools are the use of the notion of partial action and of one-dimensional geometric structures.

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: We examine properties of ttbar candidates events in lepton+jets final states to establish the helicities of the W bosons in t->W+b decays. Our analysis is based on a direct calculation of a probability that each event corresponds to a ttbar final state, as a function of the helicity of the W boson. We use the 125 events/pb sample of data collected by the DO experiment during Run I of the Fermilab Tevatron collider at sqrt{s}=1.8 TeV, and obtain a longitudinal helicity fraction of F_0=0.56+/-0.31, which is consistent with the prediction of F_0=0.70 from the standard model.

description: The object relations of three groups of unwed adolescent women were examined and compared: primiparas who sought abortion, primiparas who opted for teleo-cyesis and never-pregnant sexually active girls. The difference in the perception of early love objects and relation to age appropriate objects was examined. A difference between the Teleo-cyesis and Never-Pregnant groups was predicted. Subjects were 45 white, non-Catholic, middle-to-upper class adolescents, 15 to 18 years of age. They were given: (1) a structured interview; (2) the Parent-Child Interaction Rating Scale-Nurturance; (3) The Parent-Child Interaction Rating Scale-Autonomy; and (4) the Affectional Orientation Questionnaire (Parents vs. Peers). The one-way ANOVA and Student's t-test for comparisons were used at p < .05 level of significance. The results indicated: (1) All adolescents had reached age appropriate object relations and perceived them to be of good quality. (2) The Never-Pregnant group perceived receiving more security from their mother then the other two groups. (3) All adolescents perceived themselves as autonomous and independent. (4) All adolescents felt closer to their friends than to their parents. In addition, the Never-Pregnant group felt closer to their fathers than to their mothers (F = 5.58, p < .05). (5) All adolescents considered themselves as the significant decision-makers for everyday life situations. The structured interview indicated that: The majority of the Teleo-cyesis and Abortion group adolescents decided on their own to abort or to carry to term. The majority of the Never-Pregnant group were influenced by a girlfriend to use birth control. There were more object losses through divorce for the Teleo-cyesis group. The parents of the latter group had a lower educational level and the adolescents' scholastic performance was lower than that of the Never-Pregnant group.
