description: We investigate the production of the pentaquark $Θ^+$ baryon via the $γn\to K^-Θ^+$ and $γp\to \bar{K}^0 Θ^+$ processes, focusing on the parity of the $Θ^+$. Using the effective Lagrangians, we calculate the total and differential cross sections with the spin of the $Θ^+$ presumed to be 1/2. We employ the coupling constant of the $KNΘ$ vertex determined by assuming its mass and the decay width to be $1540 {\rm MeV}$ and $15 {\rm MeV}$. That of the $K^*NΘ$ is taken to be about a half of the $KNΘ$ coupling constant. We estimate the cutoff parameter by reproducing the total cross section of the $γp \to K^+ Λ$ reaction. It turns out that the total cross section for the $γn\to K^- Θ^+$ process is about four times larger than that of the $γp\to\bar{K}^0Θ^+$. We also find that the cross sections for the production of the positive-parity $Θ$ are about ten times as large as those for the negative-parity ones.

description: This study examined the effect of audit committee characteristics on audit report lag of listed consumer goods companies in Nigeria. Data for the study were derived from annual reports of ten consumer goods companies listed on the Nigerian Stock Exchange for the period 2012 to 2022. The data were analyzed using auto regressive distributive lag and the regression estimation results revealed that a positive and significant relationship exists between audit committee size, audit committee independence, audit committee expertise. Positive but insignificant relationship between audit committee meetings and audit report lag, positive and significant relationship exist between leverage and audit report lag, a negative and insignificant relationship between board size and audit report lag of listed consumer goods companies in Nigeria. The study concluded that audit committee size, independence and expertise affect audit report lag while audit committee meeting does not affect audit report lag. Therefore, the study recommends that membership of audit committee should possess some level of knowledge and experience in accounting profession to understand all aspects of accounting to be able to carry out their functions well. Government should make a policy that can categorically spell out the days allowed for reporting of audited financial statements of companies in order to reduce audit lag.

description: Since the 1960s, white working-class politics has been explained in terms of backlash: because of black civil rights gains, once "liberal" voters became conservative and abandoned the Democratic Party. But there was more continuity than change in postwar blue-collar political consciousness. Working whites were New Deal liberals only in the most limited sense: they valued New Deal promises of blue-collar economic security but suspected broader goals of social equality. This study of white working-class institutions, electoral politics, and community protest finds that blue-collar allegiance to the Democratic Party stemmed from a distinctive white working-class political consciousness rooted in the community rather than the workplace. This political consciousness emphasized community obligations and responsibilities over rights, although rights became increasingly important. In 1940s Baltimore, Democratic politicians upheld blue-collar institutions--industrial employment and white neighborhoods--while leaving racial exclusion unchallenged. Blue-collar anticommunism, shaped by local experience, redirected populist attacks away from business elites toward political and intellectual liberals. When, in the 1950s, residential and school desegregation grew threatening, working whites expressed their discontent in racial terms. This political language of "white rights" was, however, both indefensible and inaccurate. During the 1960s, as crime rates rose and public institutions increasingly seemed responsive to minorities and indifferent toward working whites, blue-collar discontent focused more on liberal elites who fostered social change than on blacks. Working whites' political consciousness remained rooted in the white community, but their political language now emphasized populist claims to the rights of "working" people--claims difficult to discredit on racist grounds. Most blue-collar Baltimore voters remained loyal to the Democratic party up to 1980, not because it was the party of liberalism but because they considered it the party of the blue-collar city. This vision likely weakened thereafter, but white working-class convictions regarding the value of majoritarian democracy and the inherent limits of political solutions remained to reshape the politics of the 1980s and 1990s.

description: When short-range attractions are combined with long-range repulsions in colloidal particle systems, complex microphases can emerge. Here, we study a system of isotropic particles which can form lamellar structures or a disordered fluid phase when temperature is varied. We show that at equilibrium the lamellar structure crystallizes, while out of equilibrium the system forms a variety of structures at different shear rates and temperatures above melting. The shear-induced ordering is analyzed by means of principal component analysis and artificial neural networks, which are applied to data of reduced dimensionality. Our results reveal the possibility of inducing ordering by shear, potentially providing a feasible route to the fabrication of ordered lamellar structures from isotropic particles.

Fiscal deficit, the parallel market for foreign exchange and money supply endogeneity in Nigeria
Creators: name: Fahm, Iyabode Adetoun Jumoke
Publisher: name: American University
Year: 2023

description: The main purpose of this dissertation is develop a model of inflation and monetary financing of fiscal deficits emphasizing the role of the parallel exchange rate, which is tested using data from Nigeria. The main point of departure from existing theoretical models, which emphasize an asset motive for holding parallel foreign currency, is the specification of a transaction demand for parallel currency arising from the demand for unofficial imports. The inclusion of a transaction motive in the model of the parallel market for foreign exchange results in the possibility of a stable steady state, in addition to the saddle path equilibrium that results in a model with only an asset motive. In addition, comparative static exercises show that the effects of devaluation policy, reserve policy, and fiscal policy on the parallel exchange rate premium depend on the relative strength of the asset and transaction motives in the demand for parallel currency. For exogenous changes in the price of exports, the effect on the parallel market premium is definitely negative regardless of the relative strength of the two motives for holding foreign currency. A structural econometric model uses two-stage least squares instrumental variables to estimate the equations for the parallel exchange rate and the inflation rate using annual data for Nigeria. Transaction motive variables are somewhat stronger and more significant than asset motive variables in the reduced form equation for the parallel market exchange rate. For the inflation rate the structuralist model provided stronger results than the monetarist model. The approximation of the money stock identity around the sample means shows that domestic credit to the government and the private sector were roughly equal components of the increase in the money supply. A Vector Autoregression model was estimated using quarterly data for the parallel market exchange rate, the stock of money and the price level series, all measured in differences of the natural logarithms for reasons of stationarity. The parallel market exchange rate and prices, and to a lesser extent, money and prices have two-way causal relationships. No causality is found between money and the parallel market exchange rate.

description: The purpose of this study was to explore the effects of the use of the Texas Instrument Graphing Calculator (TI-82) on the achievement and attitude of learning disabled students in a university finite mathematics class. The exploratory study investigates the following issues: (1) Do learning disabled students in the study have preferences for various representations, in a graphing calculator-based instructional environment in a finite mathematics course? (2) To what extent are preferences contextually related as measured by a researcher-designed representations of functions test? (3) Did the use of the graphing calculator result in more positive attitudes of the subjects about mathematics as measured by the Aiken's Revised Mathematics Attitude Scale? (4) Were the learning disabled students who used the graphing calculator in finite mathematics more likely to enroll in more advanced mathematics courses?; A significant result of this exploratory investigation indicates that one of the learning disabled students in the study did have preferences regarding representations of functions. More research needs to be done to determine whether learning disabled students' preferences of representations of functions in contextual and noncontextual settings are similar for students in a graphing calculator-based environment as for traditional students. Moreover, to what extent the presence and use of the calculator affects these preferences needs additional study. Recommendations for further research are outlined.

Strangers in a middle land: Italian immigrants and race relations in Baltimore, 1890-1920
Creators: name: Shufelt, Gordon H.
Publisher: name: American University
Year: 2023

description: This dissertation examines relations between African-Americans and Italian immigrants during the early development of the Italian-immigrant community in Baltimore. The first part includes a summary of the social, political, and economic circumstances in which interactions between African-Americans and Italian immigrants occurred at the end of the nineteenth century. The second part traces the development of relations between these two groups as the people of Baltimore lived through a series of crises, including a major fire in the central business district, two attempts to disfranchise African-Americans, and a series of ordinances intended to exclude African-Americans from living in predominantly white neighborhoods. The crises that occurred in the early twentieth century presented bases for cooperation as well as conflict between African-Americans and Italian immigrants. Both groups faced difficulties as a result of lost jobs following the fire. In the disfranchisement campaigns of 1905 and 1909, African-Americans and Italian immigrants faced similar political concerns, as the disfranchisement plans jeopardized the voting rights of all persons not descended from a person who had been eligible to vote in 1869--a category that included recent immigrants as well as African-Americans. Housing segregation ordinances directed against African-Americans raised the possibility that similar ordinances might be used against immigrants. On the other hand, African-Americans and Italian immigrants had similar employment skills and competed for jobs and housing. Despite the potential for both cooperation and conflict, Italian immigrants in Baltimore developed attitudes about race relations that discouraged cooperation with African-Americans, even in circumstances in which African Americans and Italian immigrants had common interests. The cultural adjustment of Italian immigrants to a racially and ethnically diverse society in Baltimore was the product of interactions with not only African-Americans, but also Baltimore's many other ethnic communities. Through these interactions, Italian immigrants learned that in America, African-Americans were defined as permanent outsiders, and for newcomers, such as Italian immigrants, it was important to separate themselves African-Americans.

description: We present observations of the star formation region NGC 7129 taken with the Multiband Imaging Photometer for Spitzer (MIPS). A significant population of sources, likely pre-main sequence members of the young stellar cluster, is revealed outside the central photoionization region. Combining with Infrared Array Camera (IRAC) and ground-based near-infrared images, we have obtained colors and spectral energy distributions for some 60 objects. The [3.6]-[4.5] vs. [8]-[24] color-color plane shows sources clustered at several different loci, which roughly correspond to the archetypal evolutionary sequence Class 0, I, II, and III. We obtain preliminary classifications for 36 objects, and find significant numbers of both Class I and II objects. Most of the pre-main sequence candidates are associated with the densest part of the molecular cloud surrounding the photoionization region, indicating active star formation over a broad area outside the central cluster. We discuss three Class II candidates that exhibit evidence of inner disk clearing, which would be some of the youngest known examples of a transition from accretion to optically thin quiescent disks.

description: This investigation examined the relationship between the ability to identify and interpret emotional stimuli and the symptoms of violence and aggression. A group of violent and non-violent male offenders completed the Comprehensive Affect Battery (CAB), a compendium of tests designed to assess various aspects of emotion perception including: facial expression, body posture, auditory cues of emotion, and social-situational cues. Each subject also completed three measures designed to measure personality characteristics and empathic ability. Information regarding each subject's medical, psychological, and offense history was obtained in order to illuminate the potential impact of such factors on test performance. Subjects completed a neuropsychological screening as a general measure of cognitive-intellectual functioning. Results indicated that there were no significant differences between the violent and non-violent offenders in their ability to identify and interpret emotional cues. Furthermore, the groups did not differ on their capacity to empathize with the emotional experience of others. An explanation for these findings is provided and implications for future research are discussed.

We compare this tensor to the polarization tensor of eventual surface mode (which is a $2+1$ dimensional Dirac fermion) and find essential differences in the conductivities in both Hall and normal sectors. Thus, the interaction with electromagnetic field near the boundary differs significantly in the full model and in the effective theory for the surface mode.

description: We present a systematic phase curve analysis of known transiting systems observed by the Transiting Exoplanet Survey Satellite (TESS) during year one of the primary mission. Using theoretical predictions for the amplitude of the planetary longitudinal atmospheric brightness modulation, stellar ellipsoidal distortion and Doppler boosting, as well as brightness considerations to select targets with likely detectable signals, we applied a uniform data processing and light-curve modeling framework to fit the full-orbit phase curves of 22 transiting systems with planet-mass or brown dwarf companions, including previously published systems. Statistically significant secondary eclipse depths and/or atmospheric brightness modulation amplitudes were measured for HIP 65A, WASP-18, WASP-19, WASP-72, WASP-100, WASP-111, WASP-121, and WASP-122/KELT-14. For WASP-100b, we found marginal evidence that the brightest region of the atmosphere is shifted eastward away from the substellar point. We detected significant ellipsoidal distortion signals in the light curves of HIP 65A, TOI-503, WASP-18, and WASP-30, with HIP 65A, TOI-503 and WASP-18 also exhibiting Doppler boosting. The measured amplitudes of these signals agree with the predictions of theoretical models. Combining the optical secondary eclipse depths with previously published Spitzer 3.6 and 4.5 $μ$m measurements, we derived dayside brightness temperatures and visible-light geometric albedos for a subset of the analyzed systems. We also calculated updated transit ephemerides combining the transit timings from the TESS light curves with previous literature values.

The impact of writing assignments in mathematics classes on language minority students' performance
Creators: name: Abu Diab, Tawfiq M.
Publisher: name: American University
Year: 2023

description: The purpose of this study was to determine the effect of writing assignments on language minority students' performance in mathematics classes. There were 120 participants in this study; the participants were thirty-two language minority students and eighty-eight native English-speaking students chosen from the finite mathematics and the basic statistics classes at the American University in Washington DC. The experiment was conducted in the fall semester of 1997. The treatment of the study was composed of writing assignments designed by the researcher given to the students in every class session except whenever they had to take an exam. The assignments were designed to conform to mathematical concepts covered in the respective course during the semester. The writing assignments were intended to enhance the students' understanding of the mathematical concepts and to improve the students' analytical skills and problem-solving techniques. A pretest exam, two in-class exams, a final exam, an attitude questionnaire, and personal interviews were used to collect data about the participants. The scores of the pretest exam were used to determine mathematical preparation level of the participants prior to the treatment. The two in-class exam scores and the final exam score were compared to the pretest to evaluate whether the writing assignments had any effect on the language minority students' mathematical performance. An attitude questionnaire and interview protocol were designed by the researcher to determine the effect of the treatment on the students' attitude toward mathematics and toward using writing to learn mathematics. Comparisons were made between the scores of the language minority students and the native English-speaking students in the control group, as well as the experimental group. The results of the comparisons illustrated that the treatment did not have a significant effect on the language minority students' performance. There was not enough evidence to suggest the language minority students benefited more than the native English-speaking students as a result of the treatment.

The scores of the pretest exam were used to determine mathematical preparation level of the participants prior to the treatment. The two in-class exam scores and the final exam score were compared to the pretest to evaluate whether the writing assignments had any effect on the language minority students' mathematical performance. An attitude questionnaire and interview protocol were designed by the researcher to determine the effect of the treatment on the students' attitude toward mathematics and toward using writing to learn mathematics. Comparisons were made between the scores of the language minority students and the native English-speaking students in the control group, as well as the experimental group. The results of the comparisons illustrated that the treatment did not have a significant effect on the language minority students' performance. There was not enough evidence to suggest the language minority students benefited more than the native English-speaking students as a result of the treatment.
The involvement and participation of African-American women college presidents in out-of-class activities during their collegiate experience: A descriptive study
Creators: name: Beck, Anna Edwards
Publisher: name: American University
Year: 2023

description: This descriptive study describes the involvement and participation of African American women college presidents in out-of-class activities during their collegiate years and ascertains their perceptions of the influence of participation on their leadership development. Out-of-class activities in this study extends Kuh's (1994) definition of out-of-class activities beyond co-curricular experiences to include extracurricular activities (e.g. sorority, student government, part-time or full-time employment); community service activities (e.g., tutoring, fund-raising for charitable organizations, elder care); and, religious activities (e.g., attending religious services, teaching Sunday school, choir membership). Data were collected from 28 African American women college presidents who participated in this study. They represent 61% of the total population of 46 African American women college presidents in 1996. The presidents completed the Extracurricular Involvement Inventory (EII) which was modified to gather information on the numbers and types of out-of-class activities in which the presidents participated, offices held in the activities and the intensity of their involvement in out-of-class activities. The areas covered by the mail survey were undergraduate data, role models and mentors, and out-of-class activities. Additionally, ten of the presidents participated in follow-up telephone interviews. The data were analyzed using qualitative analysis techniques. Conclusions from this study are: (a) African American women college presidents actively participated in a variety of out-of-class activities including performing groups, social sororities, and part-time and full-time work experiences; (b) they experienced gains in self-confidence, communication skills, public relations skills, team building skills, and networking skills; (c) undergraduate factors such as year of degree, place of residence, type of institution, and major field were not perceived as obstacles to participation in out-of-class activities; and (d) role models and mentors on-campus as well as off-campus were considered important influences on leadership development. The results indicated that African American women college presidents shared many common out-of-class experiences as undergraduates. The findings suggest that student affairs personnel can play a key role in assisting aspiring black women leaders in recognizing the potential value of involvement in out-of-class activities during their undergraduate experiences. Additional topics for further study and research are suggested.
Angular momentum I ground state probabilities of boson systems interacting by random interactions

description: In this paper we report our systematic calculations of angular momentum $I$ ground state probabilities ($P(I)$) of boson systems with spin $l$ in the presence of random two-body interactions. It is found that the P(0) dominance is usually not true for a system with an odd number of bosons, while it is valid for an even number of bosons, which indicates that the P(0) dominance is partly connected to the even number of identical particles. It is also noticed that the $P(I_{max})$'s of bosons with spin $l$ do not follow the 1/N ($N=l+1$, referring to the number of independent two-body matrix elements) relation. The properties of the $P(I)$'s obtained in boson systems with spin $l$ are discussed.

description: Methanol is the simplest of a long series of organic compounds called alcohols, consisting of a methyl group linked with a hydroxy group. The modern method of preparing methanol is based on the direct combination of carbon monoxide gas and hydrogen in the presence of a catalyst. Pure methanol is an important material in chemical synthesis. Chemical synthesis is the construction of complex chemical compounds from simpler ones. It is applied to all types of chemical compounds, but most syntheses are of organic molecules. Methanol forms explosive mixtures with air and burns with a nonluminous flame. Methanol is completely miscible in water.
