description: This dissertation presents a test of a Delaware model of prehistoric human subsistence and settlement patterns (Custer 1983a, 1984a) and a review of archeological models. The test was conducted by surveying a five percent stratified random quadrat sample of four environmental zones in the Saint Jones and Murderkill River watersheds, Kent County, Delaware. The problem which is addressed is the extent to which prehistoric human subsistence and settlement patterns and their resulting site locations can be predicted by using contemporary environmental variables and paleoenvironmental reconstructions. The research tested the following hypothesis: Assuming human adaptation to the changing environment, it is postulated that there will be concomitant changes in prehistoric subsistence and settlement patterns in the watersheds, and both these changes and the subsistence and settlement patterns can be correlated with contemporary environmental variables. Differences in numbers and locations of sites and correlations of site types with environmental variables, as predicted by a Delaware LANDSAT-generated model (Custer et al. 1986), are indicators of these changes. The null hypothesis is that: There is no correlation between prehistoric subsistence and settlement patterns and specific environmental variables as predicted by the Delaware model. The field survey tested high, medium and low probability predictions of archeological site locations based on the model. The model was determined to be 84% accurate, which is not possible by random chance. Therefore, the null hypothesis is rejected and the hypothesis is accepted. Environmental information was collected to identify any other influencing factors and recommend improvements in the model. Five recommendations for refinement of the Delaware model are offered. They are: (1) to better identify high probability areas related to marshes; (2) modify the model for the Delaware Bay Shore Zone for which the model had a low 33% accuracy rate; (3) closely analyze terraces with well drained soils as a possible predictive factor in future tests; (4) consider lower elevations (0-30 feet) as a possible predictor variable; and (5) adjust the logistical regression formula to enlarge the probability classes for high and medium probability, and reduce it for low probability.

description: In this paper, we use a case study approach to investigate the patterns of employment and income generation in cotton and rice value chains in Senegal and Benin. The purpose of the paper is to provide a comprehensive description of both value chains in both countries, emphasizing export potential and innovation entry points with the goal of assessing capacity to generate income, create jobs, and bring about food security. To this end, we have combined quantitative and qualitative data to identify direct and indirect value chains’ effects on employment and income, paying special attention to vulnerable groups such as youth, women, and informal employees. Surveys data as well as Social Accounting Matrix, have been used to assess the effects of these value chains on employment and income. Our results show strong relationships between value chains and jobs and income patterns.

description: Entropy bounds applied to a system of N species of light quantum fields in thermal equilibrium at temperature T are saturated in four dimensions at a maximal temperature T_max=M_Planck/N^1/2. We show that the correct setup for understanding the reason for the saturation is a cosmological setup, and that a possible explanation is the copious production of black holes at this maximal temperature. The proposed explanation implies, if correct, that N light fields cannot be in thermal equilibrium at temperatures T above T_max. However, we have been unable to identify a concrete mechanism that is efficient and quick enough to prevent the universe from exceeding this limiting temperature. The same issues can be studied in the framework of AdS/CFT by using a brane moving in a five dimensional AdS-Schwarzschild space to model a radiation dominated universe. In this case we show that T_max is the temperature at which the brane just reaches the horizon of the black hole, and that entropy bounds and the generalized second law of thermodynamics seem to be violated when the brane continues to fall into the black hole. We find, again, that the known physical mechanisms, including black hole production, are not efficient enough to prevent the brane from falling into the black hole. We propose several possible explanations for the apparent violation of entropy bounds, but none is a conclusive one.

description: We report on the results of a multiwavelength monitoring campaign of the bright, nearby Seyfert galaxy, Ark 120 using a ~50-day observing programme with Swift and a ~4-month co-ordinated ground-based observing campaign, predominantly using the Skynet Robotic Telescope Network. We find Ark 120 to be variable at all optical, UV, and X-ray wavelengths, with the variability observed to be well-correlated between wavelength bands on short timescales. We perform cross-correlation analysis across all available wavelength bands, detecting time delays between emission in the X-ray band and the Swift V, B and UVW1 bands. In each case, we find that the longer-wavelength emission is delayed with respect to the shorter-wavelength emission. Within our measurement uncertainties, the time delays are consistent with the τ~ λ^{4/3} relation, as predicted by a disc reprocessing scenario. The measured lag centroids are τ_{cent} = 11.90 +/- 7.33, 10.80 +/- 4.08, and 10.60 +/- 2.87 days between the X-ray and V, B, and UVW1 bands, respectively. These time delays are longer than those expected from standard accretion theory and, as such, Ark 120 may be another example of an active galaxy whose accretion disc appears to exist on a larger scale than predicted by the standard thin-disc model. Additionally, we detect further inter-band time delays: most notably between the ground-based I and B bands (τ_{cent} = 3.46 +/- 0.86 days), and between both the Swift XRT and UVW1 bands and the I band (τ_{cent} = 12.34 +/- 4.83 and 2.69 +/- 2.05 days, respectively), highlighting the importance of co-ordinated ground-based optical observations.

A Delphi study: Identifying administrative problems faced by elementary school principals in providing services for gifted and talented students
Creators: name: Garner-Gilchrist, Cathine
Publisher: name: American University
Year: 2023

description: The purpose of this study was to identify through the Delphi Technique the major problems that elementary school principals face in providing services for gifted students and to determine the specific strategies principals used to resolve these problems. Procedures. Data was collected through the Delphi Technique using 170 elementary school principals from the official list of the Office for Education Research and Information, Washington, D.C. The Delphi Technique used three rounds of questionnaires. The first questionnaire was open-ended. It allowed principals to use their own creativity in listing the problems they face in providing services for gifted students. The second questionnaire asked principals to rate the problems that had been listed on a scale of "1" to "4," with "1" being "least" and "4" being "most" important. The third questionnaire asked principals to agree or disagree with the eight "most" and "least" important problems and to provide solutions to these problems. Findings. An analysis of the data generated the following results. (1) There were 38 issues that evolved from Questionnaire I. (2) Questionnaire II generated eight "most" and "least" important issues and (3) Questionnaire II generated a consensus of agreement on six of the "most" and eight of the "least" important issues, and generated solutions to the"most" important issues. Conclusions. Elementary school principals do face many problems in providing services to gifted students, but they have specific ways of resolving these issues.

description: Background: Youth binge drinking is a major issue within the United States with consequences including drinking and driving, risky sexual behavior, victimization defined as being physically or verbally victimized at school or home and adverse hormonal function. The objective of this study was to assess the change in adolescent binge drinking between 2007 and 2017.  Methods: The Youth Risk Behavior Survey (YRBS) is a cross-sectional questionnaire conducted annually to examine self-reported youth risk behaviors. The current study focuses on risk factors for binge drinking as well as change in youth binge drinking between the 2007 and 2017 YRBS surveys. The YRBS is administered to all students within YRBS preselected districts and to standardize variation in Race and Ethnicity, gender, and grade between the 62 high school districts. The primary research outcome was binge drinking classified as a respondent who answered yes to Have you had more than 5 drinks during one drinking session in the past 30 days. The 10 year difference in frequency of demographic and risk behavior questions including alcohol consumption, physical activity, <5 hours sleep, trying cigarettes, trying various drugs and feeling sad or hopeless were calculated for total survey respondents and respondents who self-classified as binge drinkers in each year. A chi-squared analysis was used to assess the probability of association between binge drinking and demographic groups or survey questions within a the YRBS sampled population. Finally, an adjusted logistic regression was used to model whether binge drinking was statistically associated with year surveyed. Results: The difference in frequency of binge drinking within the past 30 days was 26% in 2007 versus 13.5% among 2017 survey respondents, which represents a >48% decrease between samples. The survey results showed a 33% reduction in students who reported trying alcohol and a 20% reduction in trying alcohol before age 13. A univariate analysis of other risk behavior questions with a statistically significant change over 10 years included a decrease in the use of cigarettes, cocaine, heroin, and other drugs surveyed. There has also been a 33% increase in feelings of sadness or hopelessness between the surveyed populations. Discussion: The current study supports research demonstrating a reduction in binge drinking among U.S. youth. Overall, high school students reported to be engaging less in drug and alcohol-related risk factors. The hypothesized reasons for this reduction include better legal enforcement of vendors and venues, rise of new technology of the internet and social media that provide alternative sources of entertainment, a decreased glamorization of alcohol consumption and the development of other ways to spent time.
Generalized Manna sandpile model with height restrictions

description: Sandpile models with conserved number of particles (also called fixed energy sandpiles) may undergo phase transitions between active and absorbing states. We generalize the Manna sandpile model with fixed number of particles, introducing a parameter $-1 \leq λ\leq 1$ related to the toppling of particles from active sites to its first neighbors. In particular, we discuss a model with height restrictions, allowing for at most two particles on a site. Sites with double occupancy are active, and their particles may be transfered to first neighbor sites, if the height restriction do allow the change. For $λ=0$ each one of the two particles is independently assigned to one of the two first neighbors and the original stochastic sandpile model is recovered. For $λ=1$ exactly one particle will be placed on each first neighbor and thus a deterministic (BTW) sandpile model is obtained. When $λ=-1$ two particles are moved to one of the first neighbors, and this implies that the density of active sites is conserved in the evolution of the system, and no phase transition is observed. Through simulations of the stationary state, we estimate the critical density of particles and the critical exponents as functions of $λ$.

description: We study various aspects of orientifold projections of Type IIB closed string theory on Gepner points in different dimensions. The open string sector is introduced, in the usual constructive way, in order to cancel RR charges carried by orientifold planes. Moddings by cyclic permutations of the internal N=2 superconformal blocks as well as by discrete phase symmetries are implemented. Reduction in the number of generations, breaking or enhancements of gauge symmetries and topology changes are shown to be induced by such moddings. Antibranes sector is also considered; in particular we show how non supersymmetric models with antibranes and free of closed and open tachyons do appear in this context. A systematic study of consistent models in D=8 dimensions and some illustrative examples in D=6 and D=4 dimensions are presented.

The relationship between nursing students' beliefs about mental illness and their anxiety prior to a clinical experience in psychiatric nursing
Creators: name: Keidel, Gladys Calkins
Publisher: name: American University
Year: 2023

description: This descriptive study examined nursing students' beliefs about mental illness related to their anxieties prior to entering their first clinical experience in nursing. The purposes were, first, to determine if there was a significant difference in anticipatory anxiety between nursing students immediately prior to their clinical experience in psychiatric nursing and those entering other clinical areas of nursing; second, to determine the relationship between nursing students' beliefs about mental illness and their anxiety prior to entry into the psychiatric nursing experience; third, to draw implications from the findings that may be useful to nurse educators in addressing student anxiety prior to clinical experience. The subjects were 160 junior nursing students enrolled in three collegiate nursing programs in the fall of 1987. Subjects were voluntary and anonymous. Data were collected from two groups: students prior to a clinical experience in psychiatric nursing and students prior to other clinical experiences, including medical-surgical, pediatric, and maternity nursing. Data were collected through the State-Trait Anxiety Inventory (STAI), developed by Spielberg; the Opinions About Mental Illness Questionnaire (OMI), developed by Cohen and Struening; and the Background Data Questionnaire (BDQ), developed by the author. The results of a t-test analysis of the mean of students' state anxiety scores prior to clinical experience in psychiatric nursing and other clinical experiences indicated no significant differences between the groups. Psychiatric nursing instructors, therefore, need not have a special concern about anticipatory state anxiety for their groups of nursing students. The F-test results of Pearson Product Moment Correlations varied by clinical and school groups, so solid inferences cannot be made about the associations between trait-state anxiety and the five beliefs about mental illness identified by the OMI. However, attitude orientations of authoritarianism did appear to be significantly correlated with trait and state anxiety. This correlation was particularly true of students over age 25. Nursing students prior to a clinical experience in psychiatric nursing who are made aware of the correlation between high state or trait anxiety and authoritarian attitude might want to work with their clinical instructor to further their own growth and learning about mental illness.

We find that the small-world OFC model exhibits self-organized criticality. Indeed, in this case we observe power law behavior of earthquakes size distribution with finite size scaling for the cut-off region. In the scale-free OFC model, instead, the strength of disorder hinders synchronization and does not allow to reach a critical state.

description: We compute the $β$-decay $ft$-values within the frameworks of the energy density functional (EDF) and the interacting boson model (IBM). Based on the constrained mean-field calculation with the Gogny-D1M EDF, the IBM Hamiltonian for an even-even nucleus and essential ingredients of the interacting boson-fermion-fermion model (IBFFM) for describing the neighboring odd-odd nucleus are determined in a microscopic way. Only the boson-fermion and residual neutron-proton interaction strengths are determined empirically. The Gamow-Teller (GT) and Fermi (F) transition rates needed to compute the $β$-decay $ft$-values are obtained without any additional parameter or quenching of the $g_A$ factor. The observed $\ft$ values for the $β^+$ decays of the even-even Ba into odd-odd Cs nuclei, and of the odd-odd Cs to the even-even Xe nuclei, with mass $A\approx 130$ are reasonably well described. The predicted GT and F transition rates represent a sensitive test of the quality of the IBM and IBFFM wave functions.

The relationship between levels of mathematics anxiety in elementary classroom teachers, selected teacher variables, and student achievement in grades two through six
Creators: name: Brown, Martha A.
Publisher: name: American University
Year: 2023

description: Several research studies have indicated that mathematics anxiety is a phenomenon that is fairly widespread among elementary education majors. Other studies suggest that levels of this anxiety increase with age. As one school district moves toward making the course entitled Algebra I the expected course for the majority of ninth grade students, it becomes necessary to consider the preparation students receive in the earlier grades. Specifically, mathematics instruction in the elementary school must be of the kind that allows most students to exit an arithmetic-based program by the end of grade six. The purpose of this study is to determine what factors related to teacher preparation, age, gender, grade level teaching assignment, attitudes toward mathematics and problem solving, and assignment to a magnet or comprehensive program impact on levels of mathematics anxiety and to what extent mathematics anxiety impacts student achievement. Teachers participating in this study completed an 85-item questionnaire. Multiple regressions were used to identify which of twenty-two factors most heavily impacted each of three dimensions of mathematics anxiety and the cumulative anxiety, and which dimension(s) of anxiety had the most influence on student achievement. A correlation matrix established the relationship between all pairs of factors. The results indicate that levels of mathematics anxiety are most influenced by age, experience, the highest level college mathematics content course, and attitudes toward mathematics and problem solving. Student achievement is most influenced by the grade level of instruction, and the number of college mathematics content courses the teacher has taken. Additional findings suggest that upper grade elementary teachers have had higher levels of high school mathematics and have more positive attitudes toward mathematics but less positive attitudes toward problem solving; that the more college mathematics a teacher has, the more positive that teacher's attitude toward problem solving; that teachers in magnet programs report less anxiety and better preparation; that student achievement in magnet programs does not differ significantly from student achievement in comprehensive programs; and, that students in the upper elementary grades do not experience as high a level of achievement as their counterparts in the primary grades.

description: We study the existence problem for Novikov algebra structures on finite-dimensional Lie algebras. We show that a Lie algebra admitting a Novikov algebra is necessarily solvable. Conversely we present a $2$-step solvable Lie algebra without any Novikov structure. We use extensions and classical $r$-matrices to construct Novikov structures on certain classes of solvable Lie algebras.

Mitigating decoherence in hot electron interferometry

description: Due to their high energy, hot electrons in quantum Hall edge states can be considered as single particles that have the potential to be used for quantum optics-like experiments. Unlike photons, however, electrons typically undergo scattering processes in transport, which results in a loss of coherence and limits their ability to show quantum-coherent behaviour. Here we study theoretically the decoherence mechanisms of hot electrons in a Mach-Zehnder interferometer, and highlight the role played by both acoustic and optical phonon emission. We discuss optimal choices of experimental parameters and show that high visibilities of $\gtrsim 85\%$ are achievable in hot-electron devices over relatively long distances of 10 $μ$m. We also discuss energy filtration techniques to remove decoherent electrons and show that this can increase visibilities to over $95\%$. This represents an improvement over Fermi-level electron quantum optics, and suggests hot-electron charge pumps as a platform for realising quantum-coherent nanoelectronic devices.

Solvable models of strings in homogeneous plane wave backgrounds

description: We solve closed string theory in all regular homogeneous plane-wave backgrounds with homogeneous NS three-form field strength and a dilaton. The parameters of the model are constant symmetric and anti-symmetric matrices k_{ij} and f_{ij} associated with the metric, and a constant anti-symmetric matrix h_{ij} associated with the NS field strength. In the light-cone gauge the rotation parameters f_{ij} have a natural interpretation as a constant magnetic field. This is a generalisation of the standard Landau problem with oscillator energies now being non-trivial functions of the parameters f_{ij} and k_{ij}. We develop a general procedure for solving linear but non-diagonal equations for string coordinates, and determine the corresponding oscillator frequencies, the light-cone Hamiltonian and level matching condition. We investigate the resulting string spectrum in detail in the four-dimensional case and compare the results with previously studied examples. Throughout we will find that the presence of the rotation parameter f_{ij} can lead to certain unusual and unexpected features of the string spectrum like new massless states at non-zero string levels, stabilisation of otherwise unstable (tachyonic) modes, and discrete but not positive definite string oscillator spectra.

description: We present the results of an extensive lattice calculation of the renormalization constants of bilinear and four-quark operators for the non-perturbatively O(a)-improved Wilson action. The results are obtained in the quenched approximation at four values of the lattice coupling by using the non-perturbative RI/MOM renormalization method. Several sources of systematic uncertainties, including discretization errors and final volume effects, are examined. The contribution of the Goldstone pole, which in some cases may affect the extrapolation of the renormalization constants to the chiral limit, is non-perturbatively subtracted. The scale independent renormalization constants of bilinear quark operators have been also computed by using the lattice chiral Ward identities approach and compared with those obtained with the RI-MOM method. For those renormalization constants the non-perturbative estimates of which have been already presented in the literature we find an agreement which is typically at the level of 1%.

Demand and Price Analysis

description: An ambitious survey of households in the Northeastern United States ' conducted during July of 1989 allows an unusual opportunity to make an empirical assessment of the effects upon individual resource valuations of different categories of demand for fresh-water recreational resources. The theoretical and empirical literature using contingent valuation methods to measure the demand for nonmarket goods typically emphasizes user demands only. By neglecting the magnitude of option and existence demands, the total social value of these resources (or changes in them) can be systematically understated. We are careful to address the simultaneity between demand status and individual environmental values, employing ordered probit models, censored normal regression models, and a generalization of selectivity correction models in an effort to uncover the true contribution of demand status to the explanation of resource values.
The relationship between levels of mathematics anxiety in elementary classroom teachers, selected teacher variables, and student achievement in grades two through six

description: Several research studies have indicated that mathematics anxiety is a phenomenon that is fairly widespread among elementary education majors. Other studies suggest that levels of this anxiety increase with age. As one school district moves toward making the course entitled Algebra I the expected course for the majority of ninth grade students, it becomes necessary to consider the preparation students receive in the earlier grades. Specifically, mathematics instruction in the elementary school must be of the kind that allows most students to exit an arithmetic-based program by the end of grade six. The purpose of this study is to determine what factors related to teacher preparation, age, gender, grade level teaching assignment, attitudes toward mathematics and problem solving, and assignment to a magnet or comprehensive program impact on levels of mathematics anxiety and to what extent mathematics anxiety impacts student achievement. Teachers participating in this study completed an 85-item questionnaire. Multiple regressions were used to identify which of twenty-two factors most heavily impacted each of three dimensions of mathematics anxiety and the cumulative anxiety, and which dimension(s) of anxiety had the most influence on student achievement. A correlation matrix established the relationship between all pairs of factors. The results indicate that levels of mathematics anxiety are most influenced by age, experience, the highest level college mathematics content course, and attitudes toward mathematics and problem solving. Student achievement is most influenced by the grade level of instruction, and the number of college mathematics content courses the teacher has taken. Additional findings suggest that upper grade elementary teachers have had higher levels of high school mathematics and have more positive attitudes toward mathematics but less positive attitudes toward problem solving; that the more college mathematics a teacher has, the more positive that teacher's attitude toward problem solving; that teachers in magnet programs report less anxiety and better preparation; that student achievement in magnet programs does not differ significantly from student achievement in comprehensive programs; and, that students in the upper elementary grades do not experience as high a level of achievement as their counterparts in the primary grades.
