Parenting practices among low-income parents of achieving high school students
Creators: name: Tsakalas, Roanthi C.
Publisher: name: American University
Year: 2023

description: This study employed both quantitative and qualitative methodologies to investigate the parenting practices of low income parents of achieving high school students. The study researched a sample of parents from low socioeconomic backgrounds who had high school students with 80% or above averages. Low socioeconomic background was determined by their achieving students who qualified for free or reduced lunch. These students were in grades 9-11, and attended a U.S. city public high school. The researcher surveyed the parents by mail using Moos' (1986) Family Environment Scale (FES). The results of the FES revealed that the parents surveyed in this study created home environments supportive of academic achievement. The FES contains three dimensions (Relationship, Personal Growth, and System Maintenance) and within each dimension are subscale measurements. Parents completed the survey, and the sample of parents was compared in relative terms with Moos' norm sample (1986) to determine differences. The subscales, cohesion, expressiveness and conflict within the Relationship dimension were not statistically significant. Under the Personal Growth dimension, this survey group's scores for the subscales of independence, intellectual cultural orientation and active recreational orientation were not significantly different relative to the norm sample. In terms of achievement orientation, the parents in this study had significantly higher scores relative to the norm sample. The parents in this study also possess a significantly stronger moral religious emphasis in their homes relative to the norm sample. The System Maintenance dimension proved that parents in this study had significantly different home environments relative to the norm sample. The parents in this study maintained homes which were organized and had control over their children. For the qualitative aspect of this study, the researcher interviewed five students' parents over the telephone. The interviews revealed the following parenting practices: established homework habits for their children during their primary grades, kept in contact with teachers, attended school events, planned family activities, set curfews, maintained an open line of communication, discussed the importance of academic success and career goals, and set rewards for academic achievement. All parents interviewed reflected democratic parenting and authoritative parenting as described by Baumrind (1971).

description: The anisotropic Heisenberg two-spin-1/2 model in an inhomogeneous magnetic field with both antisymmetric Dzyaloshinsky-Moriya and symmetric Kaplan-Shekhtman-Entin-Wohlman-Aharony cross interactions is considered at thermal equilibrium. Using a group-theoretical approach, we find fifteen spin Hamiltonians and as many corresponding Gibbs density matrices (quantum states) whose eigenvalues are expressed only through square radicals. We also found local unitary transformations that connect nine of this fifteen state collection, and one of them is the X quantum state. Since such quantum correlations as quantum entanglement, quantum discord, one-way quantum work deficit, and others are known for the X state, this allows to get the quantum correlations for any member from the nine state family. Further, we show that the remaining six quantum states are separable, that they are also connected by local unitary transformations, but, however, now the case with known correlations beyond entanglement is generally not available.

description: We report ten ground states arising from strong correlations in the single-orbital Hubbard model on the decorated honeycomb lattice; including Dirac metals, flat-band ferromagnets, real-space Mott insulators, dimer and trimer Mott insulators, and a spin-$1$ Mott insulator. The rich phase diagram arises from structures within the unit cell. Hence, such states are absent on simpler lattices. We argue that such insulating phases are prevalent on decorated lattices. These are found in many materials and common in coordination polymers, providing a playground to explore this physics.

description: Assuming that cosmological dark matter consists of weakly interacting massive particles, we use the recent precise measurement of cosmological parameters to predict the guaranteed rates of production of such particles in association with photons at electron-positron colliders. Our approach is based on general physical principles such as detailed balancing and soft/collinear factorization. It leads to predictions that are valid across a broad range of models containing WIMPs, including supersymmetry, universal extra dimensions, and many others. We also discuss the discovery prospects for the predicted experimental signatures.

description: Sharing of notations and theories across an inheritance hierarchy of mathematical structures, e.g., groups and rings, is important for productivity when formalizing mathematics in proof assistants. The packed classes methodology is a generic design pattern to define and combine mathematical structures in a dependent type theory with records. When combined with mechanisms for implicit coercions and unification hints, packed classes enable automated structure inference and subtyping in hierarchies, e.g., that a ring can be used in place of a group. However, large hierarchies based on packed classes are challenging to implement and maintain. We identify two hierarchy invariants that ensure modularity of reasoning and predictability of inference with packed classes, and propose algorithms to check these invariants. We implement our algorithms as tools for the Coq proof assistant, and show that they significantly improve the development process of Mathematical Components, a library for formalized mathematics.

Glancing and normal incidence CEMS study of hyperfine interactions in iron-57/gallium arsenide(110) single-crystal films
Creators: name: Wagner, Randall Paul
Publisher: name: American University
Year: 2023

description: CEMS spectra were gathered at room temperature for a series of Al overcoated $\sp{57}$Fe/GaAs(110) thin films (32-123 A) utilizing both normal and glancing incidence geometries. This research was conducted in order to investigate the effects which impurity diffusion, chemical reaction, and the Fe/substrate interface have on the hyperfine interactions within this system. All of the films were found to contain Fe nuclei with the same hyperfine field and isomer shift as is found in bulk Fe. Approximately 1-3 ML of paramagnetic Fe were also present, along with Fe atoms belonging to a solid mixture. None of the Mossbauer spectra of the bulk compounds FeAs, Fe$\sb2$As, or FeAs$\sb2$ were observed in the spectra of these films. Both the bulk-like Fe and mixture region were discovered to increase in thickness as the number of deposited Fe layers increased. In addition, the correlation between the average isomer shift and hyperfine field for part of the mixture in the thickest films was in good agreement with that found in dilute Fe-As alloys. This was not the case however, for the thinner films and that part of the mixture made up predominantly of Fe atoms which had lower hyperfine fields. Furthermore, the data revealed that the reduced magnetization previously measured in Fe/GaAs(110) thin films was not due exclusively to a decrease in the magnitude of the moment per Fe atom. Additional spectra were gathered for the 123 A film in applied magnetic fields with two different glancing geometries. The relative line intensities measured with the two geometries were compared at similar fields using a method which also incorporated the normal incidence results. From this comparison, it was discovered that 5.5% of the moment could be modeled oriented normal to the film plane with the rest confined to the film plane. Another model, which allowed for 16% of the moment to be randomly oriented while the remaining fraction was in-plane, also yielded better results than a model which assumed an entirely in-plane moment.

description: Hot cores and their precursors contain an integrated record of the physics of the collapse process in the chemistry of the ices deposited during that collapse. In this paper, we present results from a new model of the chemistry near high mass stars in which the desorption of each species in the ice mixture is described as indicated by new experimental results obtained under conditions similar to those hot cores. Our models show that provided there is a monotonic increase in the temperature of the gas and dust surrounding the protostar, the changes in the chemical evolution of each species due to differential desorption are important. The species H$_2$S, SO, SO$_2$, OCS, H$_2$CS, CS, NS, CH$_3$OH, HCOOCH$_3$, CH$_2$CO, C$_2$H$_5$OH show a strong time dependence that may be a useful signature of time evolution in the warm-up phase as the star moves on to the Main Sequence. This preliminary study demonstrates the consequences of incorporating reliable TPD data into chemical models.

Moments of the first passage time under external driving

Year: 2003
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: A general theory is derived for the moments of the first passage time of a one-dimensional Markov process in presence of a weak time-dependent forcing. The linear corrections to the moments can be expressed by quadratures of the potential and of the time-dependent probability density of the unperturbed system or equivalently by its Laplace transform. If none of the latter functions is known, the derived formulas may still be useful for specific cases including a slow driving or a driving with power at only small or large times. In the second part of the paper, explicite expressions for mean and variance of the first passage time are derived for the cases of a linear or a parabolic potential and an exponentially decaying driving force. The analytical results are found to be in excellent agreement with computer simulations of the respective first-passage processes. The particular examples furthermore demonstrate that already the effect of a simple exponential driving can be fairly involved implying a nontrivial nonmonotonous behavior of mean and variance as functions of the driving's time scale.

description: A correlational study was conducted to investigate the nature of personal standards in 101 students with a range of depressive symptoms and affect intensity. Three types of goals were measured: Personal standards as measured by a perfectionism scale, standards related to interpersonal interactions in various social settings, and standards of performance on a creative empathy task. When questionnaires were used to assess subjects' personal standards (e.g., the Personal Standards Subscale and the ICQ), there were no differences between the goals of subjects with higher or lower depressive symptoms. However, when an achievement task was used, one of the goal measures (minimal standards on the task) was predicted by the interaction of affect intensity and depressive symptoms: Subjects who were below the mean on both affect intensity and depressive symptoms set the lowest minimal standards.
On instanton contributions to anomalous dimensions in N=4 supersymmetric Yang-Mills theory
Creators: name: Kovacs, Stefano
Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Theory (hep-th)

description: Instanton contributions to the anomalous dimensions of gauge-invariant composite operators in the N=4 supersymmetric SU(N) Yang-Mills theory are studied in the one-instanton sector. Independent sets of scalar operators of bare dimension 2, 3, 4 and 5 are constructed in all the allowed representations of the SU(4) R-symmetry group and their two-point functions are computed in the semiclassical approximation. Analysing the moduli space integrals the sectors in which the scaling dimensions receive non-perturbative contributions are identified. The requirement that the integrations over the fermionic collective coordinates which arise in the instanton background are saturated leads to non-renormalisation properties for a large class of operators. Instanton-induced corrections to the scaling dimensions are found only for dimension 4 SU(4) singlets and for dimension 5 operators in the representation [0,1,0] of SU(4). In many cases the non-renormalisation results are argued to be specific to operators of small dimension, but for some special sectors it is shown that they are valid for arbitrary dimension. Comments are also made on the implications of the results on the form of the instanton contributions to the dilation operator of the theory and on the possibility of realising its action on the instanton moduli space.

At planar one-loop level in SYM, by solving the thermodynamic limit of the Bethe ansatz equations for an integrable open spin chain, we find good agreement with string theory predictions for energies of both circular and folded two-spin solutions. A universal relation between the open and closed spinning strings is verified in the spin chain approach.

Attitudes toward death and belief in afterlife: An exploratory study of the mediating roles of denomination and gender among adults in the middle and later years
Creators: name: Heffernan, Margaret Mary
Publisher: name: American University
Year: 2023

description: This study attempted to more precisely define the multiple meanings--positive and negative--that death and afterlife hold for adult Christians in their middle and later years and the relationship of these meanings to four measures of religiosity. Moreover, the study was a first attempt to investigate how denomination might mediate adults' attitudes toward death and beliefs in afterlife. Of 302 questionnaires administered to men and women aged 40 to 88 years, 275 were returned across three religious groups: Roman Catholic, Mainline Protestant, and Pentecostal. Results lend strong support for the role of denomination and focal support for the roles of age group and gender as mediating factors in adult attitudes toward death and afterlife. As hypothesized, intensity of belief and/or intensity of experience of God was the most salient dimension in distinguishing among religious groups. Differences between middle aged and older adults' attitudes and beliefs are discussed in the light of Butler's notion of life review and Erikson's adult developmental stage of integrity vs. despair.

description: Deep learning-based object detection algorithms enable the simultaneous classification and localization of any number of objects in image data. Many of these algorithms are capable of operating in real-time on high resolution images, attributing to their widespread usage across many fields. We present an end-to-end object detection pipeline designed for real-time rare event searches for the Migdal effect, using high-resolution image data from a state-of-the-art scientific CMOS camera in the MIGDAL experiment. The Migdal effect in nuclear scattering, crucial for sub-GeV dark matter searches, has yet to be experimentally confirmed, making its detection a primary goal of the MIGDAL experiment. Our pipeline employs the YOLOv8 object detection algorithm and is trained on real data to enhance the detection efficiency of nuclear and electronic recoils, particularly those exhibiting overlapping tracks that are indicative of the Migdal effect. When deployed online on the MIGDAL readout PC, we demonstrate our pipeline to process and perform the rare event search on 2D image data faster than the peak 120 frame per second acquisition rate of the CMOS camera. Applying these same steps offline, we demonstrate that we can reduce a sample of 20 million camera frames to around 1000 frames while maintaining nearly all signal that YOLOv8 is able to detect, thereby transforming a rare search into a much more manageable search. Our studies highlight the potential of pipelines similar to ours significantly improving the detection capabilities of experiments requiring rapid and precise object identification in high-throughput data environments.

description: We use density functional molecular dynamics (DFT-MD) to study the effect of finite temperature exchange-correlation (xc) in Hydrogen. Using the Kohn-Sham approach, the xc energy of the system, $E_{xc}(r_{s})$ is replaced by the xc free energy $f_{xc}(r_{s},Θ)$ within the local density approximation (LDA) based on parametrized path integral Monte Carlo (PIMC) data for the uniform electron gas (UEG) at warm dense matter (WDM) conditions. We observe insignificant changes in the equation of state (EOS) at the region of metal-insulator transition compared to the regular LDA form, whereas significant changes are observed for T$>$10000 K, i.e., in the important WDM regime. Thus, our results further corroborate the need for temperature-dependent xc functionals for DFT simulations of WDM systems. Moreover, we present the first finite-temperature DFT results for the EOS of Hydrogen in the electron liquid regime up to $r_{s}=14$ and find a drastic impact (about $20\%$) of thermal xc effects, which manifests at lower temperatures compared to WDM. We expect our results to be important for many applications beyond DFT, like quantum hydrodynamics and astrophysical models.

description: Current text visualization techniques typically provide overviews of document content and structure using intrinsic properties such as term frequencies, co-occurrences, and sentence structures. Such visualizations lack conceptual overviews incorporating domain-relevant knowledge, needed when examining documents such as research articles or technical reports. To address this shortcoming, we present ConceptScope, a technique that utilizes a domain ontology to represent the conceptual relationships in a document in the form of a Bubble Treemap visualization. Multiple coordinated views of document structure and concept hierarchy with text overviews further aid document analysis. ConceptScope facilitates exploration and comparison of single and multiple documents respectively. We demonstrate ConceptScope by visualizing research articles and transcripts of technical presentations in computer science. In a comparative study with DocuBurst, a popular document visualization tool, ConceptScope was found to be more informative in exploring and comparing domain-specific documents, but less so when it came to documents that spanned multiple disciplines.

description: Practical and theoretical approaches employed by the public administration community to understand and improve civil service performance have failed to adequately address the utility of exploiting nonmonetary motivations. Reformers too often view civil servants as self-interested rational utility maximizers motivated primarily, if not solely, by the need for economic rewards in the form of pay, job security, promotions, and benefit packages. This study attempts to balance this bias by exploring extra-rational interests in the form of helping others and accomplishing something worthwhile for society. These interests define the public service ethic. The premise of this inquiry is that a strong public service ethic is not only a valuable and underappreciated resource, it is a necessary condition for good government. The theoretical rationale for a public service ethic is based on organizational theory, principal-agent models, and political control. This study uses data from Federal Employee Attitude Surveys, General Social Surveys, and a survey conducted for the Institute of Electronics and Electrical Engineers to estimate, evaluate, and compare public and private sector employee reward orientations. Bivariate and multivariate statistical techniques estimate differences between sectors, control for the impact of individual characteristics on reward orientations, and provide insight into the effects of incongruence between individual and agency reward orientations on job commitment and work effort. The empirical evidence supports the conclusion that public sector employees place greater value in service interests than private sector employees, with individual characteristics such as pay, administrative position, and professional status having a positive effect on service orientations. In the public sector, economic oriented employees are less committed to the organization and more likely to limit individual work effort. The practical implication of these results is that the match between individual reward expectations and those shared by agency peers has a significant and positive impact on job commitment and work effort. This study concludes that the public sector workforce is not representative of the general public when approached from the perspective of reward preferences. The practical implication of this conclusion is that a public service ethic is an important consideration in recruiting, retaining, and motivating public employees.

The public service ethic
Creators: name: Crewson, Philip Edwin
Publisher: name: American University
Year: 2023

description: Practical and theoretical approaches employed by the public administration community to understand and improve civil service performance have failed to adequately address the utility of exploiting nonmonetary motivations. Reformers too often view civil servants as self-interested rational utility maximizers motivated primarily, if not solely, by the need for economic rewards in the form of pay, job security, promotions, and benefit packages. This study attempts to balance this bias by exploring extra-rational interests in the form of helping others and accomplishing something worthwhile for society. These interests define the public service ethic. The premise of this inquiry is that a strong public service ethic is not only a valuable and underappreciated resource, it is a necessary condition for good government. The theoretical rationale for a public service ethic is based on organizational theory, principal-agent models, and political control. This study uses data from Federal Employee Attitude Surveys, General Social Surveys, and a survey conducted for the Institute of Electronics and Electrical Engineers to estimate, evaluate, and compare public and private sector employee reward orientations. Bivariate and multivariate statistical techniques estimate differences between sectors, control for the impact of individual characteristics on reward orientations, and provide insight into the effects of incongruence between individual and agency reward orientations on job commitment and work effort. The empirical evidence supports the conclusion that public sector employees place greater value in service interests than private sector employees, with individual characteristics such as pay, administrative position, and professional status having a positive effect on service orientations. In the public sector, economic oriented employees are less committed to the organization and more likely to limit individual work effort. The practical implication of these results is that the match between individual reward expectations and those shared by agency peers has a significant and positive impact on job commitment and work effort. This study concludes that the public sector workforce is not representative of the general public when approached from the perspective of reward preferences. The practical implication of this conclusion is that a public service ethic is an important consideration in recruiting, retaining, and motivating public employees.
Converting America: Three community efforts to end the Cold War, 1956-1973
Creators: name: Smith, Allen
Publisher: name: American University
Year: 2023

description: The Syracuse Peace Council (SPC), the New Jersey Committee for a SANE Nuclear Policy (NJSANE), and the St. Louis Committee for Nuclear Information (CNI) were three of the most important peace groups in Cold War America. Far more than just local groups, the SPC, NJSANE, and CNI also belonged to three distinct national political communities committed respectively, to religious witness, socialist principles, and scientific ideals. The study of those three communities through the lens of their strongest local affiliates reveals a broader, more radical, and more enduring peace movement. This more complex social movement belies accounts that have emphasized the importance of radioactive fallout in generating a renewed peace movement. Although all peace activists believed fallout was a serious health hazard, most concerned themselves with the issue of nuclear testing primarily to communicate their ideas about altering international relations and transforming American society, in effect, ending the Cold War at home and abroad. This campaign assailed the bipartisan consensus of the Republican and Democratic Parties and linked peace and social change in an optimistic fashion absent since the 1930s. This study also contests the view that male pacifists dominated the peace movement. Many peace activists came from the Communist Party. Their continued activism must be included in any account of the Old Left. In addition, the presence of a large number of female peace activists in an era that trumpeted domestic female roles indicates the need to continue rethinking women's roles during the Cold War. All three groups began before, and survived after, the 1960s, a fact that refutes efforts to isolate radicalism to a single decade. The enduring efforts of older peace activists to oppose the Cold War challenges the notion the 1960s student movement spawned the New Left. Social change started earlier within a far wider segment of American society. The continued activism of the SPC, NJSANE, and CNI into the 1970s also extends the legacy of this broader New Left. The peace movement, while never successfully creating a sustained mass constituency for an alternative to the Cold War, did alter American society in important ways.

description: We survey the underlying theory behind the large-scale and linear scaling DFT code, Conquest, which shows excellent parallel scaling and can be applied to thousands of atoms with exact solutions, and millions of atoms with linear scaling. We give details of the representation of the density matrix and the approach to finding the electronic ground state, and discuss the implementation of molecular dynamics with linear scaling. We give an overview of the performance of the code, focussing in particular on the parallel scaling, and provide examples of recent developments and applications.

You Can Take it with You! The Returns to Foreign Human Capital of Male Temporary Foreign Workers

description: The research on immigration has found falling labor market outcomes of immigrants in many Western countries. In Canada, one of the major causes has been the decline in the returns to foreign work experience. Using the 1991, 1996 and 2001 Canadian Census Master Datafiles and applying both parametric and semiparametric techniques, it is found that unlike recently landed male immigrants, temporary foreign workers have no difficulty transferring their human capital to the Canadian labor market and in particular, they obtain very high returns to their foreign work experience. This is even true for temporary foreign workers from non-traditional backgrounds, a group that has had particular difficulty receiving returns to their foreign work experience for recent immigrant cohorts and now composes the majority of Canada’s immigration. It is likely that this premium can be partially attributed to the different selection process that temporary foreign workers and immigrants enter Canada under. While immigrants for the most part are selected by the government, the selection process for temporary foreign workers is driven by employers and employers may be better able to assess the transferability of the worker’s foreign human capital.

description: Jagannathan andWang (1996) derive the asymptotic distribution of the Hansen-Jagannathan distance (HJ-distance) proposed by Hansen and Jagannathan (1997), and develop a specification test of asset pricing models based on the HJ-distance. While the HJ-distance has several desirable properties, Ahn and Gadarowski (2004) find that the specification test based on the HJ-distance overrejects correct models too severely in commonly used sample size to provide a valid test. This paper proposes to improve the finite sample properties of the HJ-distance test by applying the shrinkage method (Ledoit and Wolf, 2003) to compute its weighting matrix. The proposed method improves the finite sample performance of the HJ-distance test significantly.

description: This paper surveys bootstrap and Monte Carlo methods for testing hypotheses in econometrics. Several different ways of computing bootstrap P values are discussed, including the double bootstrap and the fast double bootstrap. It is emphasized that there are many different procedures for generating bootstrap samples for regression models and other types of model. As an illustration, a simulation experiment examines the performance of several methods of bootstrapping the supF test for structural change with an unknown break point.
