The Influence of the Division of Planning Coordination on Regional Council Development in Texas

Description: This study focuses on the role of the Texas Governor's Office in the development of regional councils of governments in Texas. The study, divided into six chapters, emphasizes three important points: first, that Governor Connally conceived the idea of a "Division of Planning Coordination" due to his desire to be a strong chief executive; second, that the staff he hired largely to fulfill this desire in turn convinced the Governor that regional councils of governments should be an element of the statewide planning and development system and should receive strong financial and policy support from the Governor; and third, that from January 1969 to January 1973, the statewide regional council network was completed and Texas became a recognized national leader in the use of the regional council concept.

The Effect of Religiosity Upon Anxiety

Description: A problem that has interested the writer is the effect of religion upon mental health. Are very religious people more or less healthy than not-so religious people? Could there be no relationship between degree of religiosity and mental well-being? Some of the reviewed literature seemed to show that religion may reduce anxiety (Cole & Spurgeon, 1960, Cooley & Hutton, 1965), other studies showed no relationship between them (Bradbury, 1967, Glass, 1955), while some experiments indicated that religious individuals showed poor mental health (Dunn, 1965, Rokeach, 1960). The study presented herein is an attempt to further delineate the effect of religion upon mental stability or, more specifically, anxiety. Religion may involve many dimensions rather than just one specific aspect. For the aforementioned reason, the present study considered the ideological, intellectual, experiential, ritualistic, and consequential aspects of religion. The relationship of anxiety to these variables was studied. Finally, the writer attempted to observe the effect of religious affiliation upon anxiety. The purpose of the present study was to (1) consider the empirical relationship of religiosity to anxiety among the low, medium, and high religious groups, and to (2) determine if different religious affiliations have a significant or non-significant relationship to anxiety scores. A questionnaire developed by Falkner and Jong (1963) was employed to measure religiosity. The Taylor Manifest Anxiety Scale was used to gauge anxiety.

Relationship of Leadership Importance Ratings and Leadership Competency Ratings Across Adjacent Management Levels

Description: Effective leadership can and does influence organizational performance. The Executive Success Profile, a multi-rater feedback instrument, was used to gather perception data on 51 executives and 310 senior managers of a large Fortune 500 electronics manufacturing company in regards to three critical leadership dimensions: visionary thinking, empowering others, and global perspective. Paired t-tests were run to compare the means of the two samples. Significant differences were found between executives and senior managers on the perceived importance of and ability to perform on the empowering others dimension. Additionally, correlational measures indicate a statistically significant relationship between importance and competence ratings on the empowering others and global perspective dimensions for executives, and on the empowering others dimension for senior managers.

Dramatizing Lynching and Labor Protest: Case Studies Examining How Theatre Reflected Minority Unrest in the 1920S and 30S

Description: Theatre is widely unrecognized for the compelling influence it has held in society throughout history. In this thesis, I specifically examine the implications surrounding the social protest theatre of black and Jewish American minority communities in the first half of the twentieth century. I discuss how their historical circumstance, culture, and idiosyncratic natures caused them to choose agitated propaganda theatre as an avenue for protest. I delve into the similarities in circumstance, but their theatre case studies separate the two communities in the end. I present case studies of each community, beginning with anti-lynching plays of the 1920s that were written by black American playwrights both in response to white supremacist propaganda theatre and to assert a dignified representation of the black community. However, their plays and protest movement never developed a larger popular following. My next minority theatre case study is an examination of 1930s Jewish labor drama created in protest of popular anti-Semitic theatre and poor labor conditions. The Jewish community differs from the black community in their case because the racist propaganda was produced by a man who was Jewish. Another difference is that their protest theatre was on the commercial stage by this point because of a rise in a Jewish middle class and improvement of circumstance. Both the Jewish protest theatre and labor reform movements were more successful. My conclusion is a summation of black and Jewish American theatre of the era with a case study of collaboration between the communities in George Gershwin’s operetta about black Americans, Porgy and Bess. I conclude that these two communities eventually departed from circumstance and therefore had differing theatrical, political, and social experiences in America during the 1930s.

Hawthorne's Use of Symbolism in Four Romances

Description: This thesis is a study of the four long romances, The Scarlet Letter, The House of the Seven Gables, The Blithedale Romance, and The Marble Faun, with emphasis upon Hawthorne's use of symbolism as a means of presenting the basic moral and spiritual truths of human life. The first chapter explains the nature of symbolism and the reasons why Hawthorne used it so extensively. In each of the last four chapters, the symbolism in a single romance is considered for the purpose of discovering the manner and effectiveness of its use in exemplifying the central theme of that particular story. Although Hawthorne's short stories are extremely rich in symbolism, it was not possible to include them in the present study.

Assessment of the Effects of Communication Training on the Adult Elderly and the Assisting Adult Child

Description: This study examined the effects of Systematic Training for Effective Parenting (STEP) on affection, communication, and relationship between elderly parents and their assisting adult children. Twenty-eight pairs of parents and children were randomly assigned to treatment or control groups. Subjects took Quinn's Family Life Questionnaire as pre-, post-, and follow-up tests. Parents and children in the treatment groups attended a four-session STEP workshop. No significant differences were found on the 2 x 2 analysis of variance for repeated measures for the parents or adult children. Quinn's affection and relationship variables approached significance for the parents over time. His variable affection approached significance for the children over time, irrespective of group. Agreement approached significance for children in the treatment group. The results for the parents regarding affection suggest that the study may have emphasized their feelings of trust. Although the data for relationship approached significance, it was negative, indicating that parents in the treatment group may have reduced their interaction with their assisting children perhaps because they were learning new communication skills. The data for the children regarding affection approached significance, but it was negative, suggesting they felt free to question their feelings about themselves and their parents. The results for children in the treatment group regarding agreement may suggest that the study increased their awareness of areas of agreement with their parents. When the data for parents and children were compared, communication approached significance for the parents; that is, they felt more comfortable with their communication with their children than did their children. The variables affection and perception showed significance. The elderly parents perceived their relationship with their children more positively than did their children. Absence of statistically significant data may be explained because Quinn's Family Life Questionnaire was not sensitive enough. Analysis of covariance might have identified significant findings. ...

The Light of Dark-Age Athens: Factors in the Survival of Athens after the Fall of Mycenaean Civilization

Description: When looking at Dark Age Greece, one of the most important sites to consider is Athens. The Dark Age was a transitional period between the fall of Mycenaean Greece of the Bronze Age, and Archaic Greece of the Iron Age. This period is called the Dark Age because the palaces that ruled the Mycenaean age collapsed, and with them fell civilization in mainland Greece. Writing, fine art, massive architecture, trade, and luxury goods disappear from mainland Greece. But Athens survived the fall of the Mycenaeans. In order to understand the reason why Athens survived one must look at what the causes of the fall of the Mycenaeans were. Theories range from raiders and invasion, to natural disasters, such as earthquakes, droughts, and plagues. One must also examine Greece itself. The landscape and climate of Greece have a large impact on the settlement of the Greeks. The land of Greece also affects what Greek communities were able to do economically, whether a city would be rich or poor. It is because Athens is located in Attica that it survived. Attica had the poorest soil in the Mycenaean world, and was the poorest of the major cities, therefore, when looking at the collapse of the Mycenaeans being caused by people, there would be no reason for said people to raid or invade Athens and Attica. It is because Athens survives that it is such an important site. Athens survived the fall of the Mycenaeans and in doing so acts as a refugee center and a jumping off point for the remaining Mycenaeans to flee east, to the Aegean islands and Anatolia. Athens also stayed occupied during the Dark Age and because of this it was able to make some advancements. In particular Athens was a leader in mainland Greece in the development ...

Unclean Slates: Stories

Description: Unclean Slates: Stories is a collection of seven short stories that comments on the nature of family ties, and how such ties help form a sense of identity. Each story focuses on a separate protagonist, all of whom strive for a new beginning or an escape from some aspect of their current lives. The short story cycle of this collection is held together not by place or characters, but ultimately by the theme of wishing for a new beginning: they share a desire to fix some dissatisfying element of their lives. Mostly from the point of view of blue-collar characters leading mundane middle-class lives, these stories provide commentary on what it means to run from the conditions that make up one's sense of identity. Most of the revelations formed throughout these stories lead to a sense of acceptance of these conditions, and an understanding that family and history make up part of human consciousness. While the specific locations presented in these stories are not necessarily the same, each story seeks to focus on a location that proves to be fundamental to the makeup of the protagonist. The cities and geographic locations themselves are not as important as the specifics: the schools, diners, lakes, and so forth where these characters find themselves contemplating their disillusionment about where their lives have brought them. Facing everything from postpartum depression to simply missing out on a career opportunity, these characters all experience a sense of loss that brings them together in a way that is recognizable to the reader as the collection progresses.

Photon Exchange Between a Pair of Nonidentical Atoms with Two Forms of Interactions

Description: A pair of nonidentical two-level atoms, separated by a fixed distance R, interact through photon exchange. The system is described by a state vector which is assumed to be a superposition of four "essential states": (1) the first atom is excited, the second one is in the ground state, and no photon is present, (2) the first atom is in its ground state, the second one is excited, and no photon is present, (3) both atoms are in their ground states and a photon is present, and (4) both atoms are excited and a photon is also present. The system is initially in state (1). The probabilities of each atom being excited are calculated for both the minimally-coupled interaction and the multipolar interaction in the electric dipole approximation. For the minimally-coupled interaction Hamiltonian, the second atom has a probability of being instantaneously excited, so the interaction is not retarded. For the multipolar interaction Hamiltonian, the second atom is not excited before the retardation time, which agrees with special relativity. For the minimally-coupled interaction the nonphysical result occurs because the unperturbed Hamiltonian is not the energy operator in the Coulomb gauge. For the multipolar Hamiltonian in the electric dipole approximation the unperturbed Hamiltonian is the energy operator. An active view of unitary transformations in nonrelativistic quantum electrodynamics is used to derive transformation laws for the potentials of the electromagnetic field and the static Coulomb potential. For a specific choice of unitary transformation the transformation laws for the potentials are used in the minimally-coupled second-quantized Hamiltonian to obtain the multipolar Hamiltonian, which is expressed in terms of the quantized electric and magnetic fields.

"Positive" and "Negative" Characters in Joseph Conrad's Fiction

Description: This thesis is an attempt to understand Joseph Conrad's own concept of the "moral law"; what is meant by the terms "positive" and "negative," often used to describe the forces so obviously influencing his characters; and the characters, the action, and the endings as proofs of Conrad's belief in such a law and such forces.

An Evaluation of the Approaches to the Social Studies

Description: This study involves the examination of the major approaches to the social sciences in order to discover whether they are so arranged as to insure democratic practices that are implied or expressed in the Declaration of Independence, the preamble to the Constitution, and the Constitution. It involves the study of the philosophy underlying American democracy of "the yesterdays" and today. A further exploration is made to determine whether the various approaches are based on what psychology has discovered as to the way in which effective learning takes place.

Manhood in Spain: Feminine Perspectives of Masculinity in the Seventeenth Century

Description: The question of decline in the historiography of seventeenth-century Spain originally included socio-economic analyses that determined the decline of Spain was an economic recession. Eventually, the historiographical debate shifted to include cultural elements of seventeenth-century Spanish society. Gender within the context of decline provides further insight into how the deterioration of the Spanish economy and the deterioration of Spanish political power in Europe affected Spanish self-perception. The prolific Spanish women writers, in addition, featured their points of view on manhood in their works and created a model of masculinity known as virtuous masculinity. They expected Spanish men to perform their masculine duties as protectors and providers both in public and in private. Seventeenth-century decline influenced how women viewed masculinity. Their new model of masculinity was based on ideas that male authors had developed, but went further by emphasizing men treating their wives well.

The Influence of in Vitro Gill and Liver Metabolism of Xenobiotics on Fish Bioconcentration

Description: This dissertation examines the ability of in vitro biotransformation assays to provide an indication of metabolic potential. The potential for xenobiotic compounds to bioconcentrate in aquatic organisms is expressed through the bioconcentration factor (BCF). The metabolic loss of ibuprofen, norethindrone and propranolol was measured using rainbow trout (Oncorhynchus mykiss) and channel catfish (Ictalurus punctatus) gill and liver S9 fractions, microsomes and cell suspensions. Metabolic transformation rates (kM) were extrapolated from in vitro intrinsic clearance of parent compound (CLm) and integrated into a refined BCF model. In general, CLm of test compounds was greater in liver S9 fractions and hepatocytes. However, the influence of hepatic metabolism on kM and BCF was limited by hepatic blood flow (20-25%) compared to gill blood flow (~100%). A significant difference was noted between BCF solely based on KOW and BCF including kM. These studies indicate that the inclusion of kM in BCF models can bring predicted bioconcentration estimates closer to in vivo values. Primary cell suspensions are preferred over subcellular fractions as cell suspensions possess both phase I and phase II enzyme activity. Further study was conducted on ibuprofen biotransformation pathways. As fish do not contain the same cytochrome P450 (CYP) 2C homologs known to metabolize ibuprofen in mammals, it cannot be assumed that piscine biotransformation is similar. Metabolite analysis found 2-hydroxy-ibuprofen as the major metabolite in S9 and microsomal fractions. Additional assays involving the induction and inhibition of specific CYP isozymes support CYP1A2 as an alternative metabolic pathway.

Topographical analysis of reinforcement produced variability: Generalizations across settings and contingencies.

Description: This study evaluated the effects of programming a variability contingency on one object and the generalization of variability across other objects and contingencies when the defining features of the variable responses were topographical differences. A dog's interactions with five different objects were measured under both ANY (where any physical contact with the object would be reinforced on a fixed ratio schedule) and the VAR contingencies (where only the novel responses per trial would be reinforced). The ANY contingency produced stereotyped responding of behavior with all objects. When one of the dog-object interactions was changed to the VAR contingency, a marked decrease in stereotypic behavior and an increase in novel responses in the form of topographical combinations were observed across both contingencies.

Correlates of Texas Standard AP Charter Campuses and How They Compare with Standard AP Traditional Public Campuses

Description: The research sought to objectively evaluate the effectiveness of Texas standard AP open-enrollment charter school campuses and to discover independent variables that may be utilized to predict effective charter school campuses. The literature review was designed to enhance the current understanding of charter schools and therefore facilitate a more effective evaluation of them. A basic knowledge and understanding of the origins, characteristics and purposes of charters allow for a more objective analysis. The literature review covered the history of charters including their founders, characteristics, and growth patterns. The data items used in the analyses were downloaded from the 2007-2008 Academic Excellence Indicator System (AEIS), which contains a variety of data from all Texas public schools. Multiple statistical analyses were utilized including chi-square, ANOVA, multiple regression and discriminate analysis. In order to evaluate Texas standard AP open enrollment charter campuses, their accountability ratings were compared with those of standard AP traditional public school campuses. The research evaluated twelve independent variables for charter schools to determine their relationship to accountability ratings, thereby providing charter operators indicators or predictors of accountability ratings to facilitate better academic quality. By analyzing the same variables for traditional public schools as charter schools, a baseline model was developed to compare the similarities and differences with the results of the charter school analyses.

Culture and Mental Health Help-Seeking Attitudes in Mexico.

Description: This study was designed to investigate 1) the cultural factors involved with Mexican citizens' attitudes toward seeking professional psychological help and 2) Mexican citizens' explanatory models of mental distress. Questionnaire data from 110 Mexican college students indicate that those who report a higher tolerance for stigma report lower endorsement of both the construct of personalismo and the machismo. Respondents who reported more interpersonal openness also reported a lower endorsement of the machismo construct. Participants from a large city reported significantly more stigma tolerance than those from a small city. Regression analyses reveal machismo as a significant predictor of stigma tolerance. Qualitative data was collected to provide additional in-depth information. Study results could be used to provide culturally appropriate mental health services.

Simulating the Spread of Infectious Diseases in Heterogeneous Populations with Diverse Interactions Characteristics

Description: The spread of infectious diseases has been a public concern throughout human history. Historic recorded data has reported the severity of infectious disease epidemics in different ages. Ancient Greek physician Hippocrates was the first to analyze the correlation between diseases and their environment. Nowadays, health authorities are in charge of planning strategies that guarantee the welfare of citizens. The simulation of contagion scenarios contributes to the understanding of the epidemic behavior of diseases. Computational models facilitate the study of epidemics by integrating disease and population data to the simulation. The use of detailed demographic and geographic characteristics allows researchers to construct complex models that better resemble reality and the integration of these attributes permits us to understand the rules of interaction. The interaction of individuals with similar characteristics forms synthetic structures that depict clusters of interaction. The synthetic environments facilitate the study of the spread of infectious diseases in diverse scenarios. The characteristics of the population and the disease concurrently affect the local and global epidemic progression. Every cluster’ epidemic behavior constitutes the global epidemic for a clustered population. By understanding the correlation between structured populations and the spread of a disease, current dissertation research makes possible to identify risk groups of specific characteristics and devise containment strategies that facilitate health authorities to improve mitigation strategies.
