Experimental mole fraction solubilities of several carboxylic acids (2-methoxybenzoic acid, 4-methoxybenzoic acid, 4-nitrobenzoic acid, 4-chloro-3-nitrobenzoic acid, 2-chloro-5-nitrobenzoic acid,2-methylbenzoic acid and ibuprofen) and 9-fluorenone, thianthrene and xanthene were measured in a wide range of solvents of varying polarity and hydrogen-bonding characteristics. Results of these measurements were used to calculate gas-to-organic solvent and water-to-organic solvent solubility ratios, which were then substituted into known Abraham process partitioning correlations. The molecular solute descriptors that were obtained as the result of these computations described the measured solubility data to within an average absolute deviation of 0.2 log units. The calculated solute descriptors also enable one to estimate many chemically, biologically and pharmaceutically important properties for the ten solutes studied using published mathematical correlations.

The purpose of this study was to determine whether working in the field of deaf education, as opposed to general education, results in a higher level of technology integration. A secondary goal was to determine if deaf educators who are deaf integrate technology at a higher level than their hearing counterparts. The instrument chosen for this study was the LoTi Technology Use Profile, a tool used to explore the role of technology in the classroom. A total of 92 participates were included in the study of which 48 were regular educators and 44 were deaf educators. The participants were selected from a population pool whereby teachers were presumably pre-disposed to using technology based upon their attendance at a technology training session in the form of a conference or a class. Deaf educators as a whole did not perform as well as general educators on the LoTi scales. Given the fact that the technology-minded general educators who comprised the sample population of this study scored exceptionally high on the LoTi scales, further research is needed to ensure comparability between the two groups. The findings of the current study do suggest, though, that deaf educators who are deaf have the potential to …

This thesis examines images of women shopping in the art of Kenneth Hayes Miller and Reginald Marsh during the 1920s and 1930s. New York City's Fourteenth Street served Kenneth Hayes Miller and Reginald Marsh, respectively, as a location generating the inspiration to study and visually represent its contemporaneity. Of particular interest to this thesis are relationships between developments in shopping and the images of women shopping in and around Fourteenth Street that populate the paintings of Miller and Marsh. Although, as Ellen Todd Wiley has shown, the emerging notion of the New Woman helped to shape female identity at this time, what remains unstudied are dimensions that geographically specific, historical developments in shopping contributed to the construction of female identity which, this thesis argues, Marsh and Miller related to, by locating in, the department store and bargain store.

This study examines the factors that have contributed to the success of some Central and Eastern European countries to improve their health care sector in the post communist period, while leaving others to its demise. While most literature has been focused on the political and economic transition of Eastern Europe, very little research has been done about the welfare aspects of the transition process, especially the health care sector. While the focus on political consequences and main macroeconomic reforms has shed light on many important processes, the lack of research of health care issues has lead to consequences on our ability to understand its impact on the future of the new democracies and their sustainability. This model looks at the impact of international (World Bank) and domestic institutions, corruption and public support and how they affect the ability of some countries to improve and reform their health care sector in the post-transition period.

This study employed a multivariate, multidimensional approach to understanding psychosocial and personality variables associated with institutional maladjustment and recidivism among youthful offenders. Participants included nine hundred serious and chronic male youthful offenders incarcerated in the Texas Youth Commission (TYC); sample sizes varied by analysis. Empirically-validated psychosocial factors (e.g., intelligence, home approval status), past criminal history variables, and two self-report personality measures of empathy and hostility were entered into hierarchical regression and structural equation modeling (SEM) analyses to predict institutional behavior and recidivism at one- and three-year intervals after release from the TYC. Confirmatory factor analysis of the personality measures revealed one underlying factor indicative of their theoretical constructs of empathy and hostility. Some differences were noted between youth in the specialized treatment programs; however, effect sizes were small to moderate. Overall, regression and SEM results indicated the variables accounted for a meaningful proportion of the variance in the outcomes. Specifically, although length of stay in the TYC was associated with institutional behavior, younger age of onset, higher hostility, and greater home disapproval also contributed significantly. Past criminal behavior was predictive of future reoffending, but lower empathy, greater home disapproval, and younger age of onset accounted for a substantial portion of …

This study examined the home-based family literacy practices of one Hispanic family, especially focusing on the parents' memories of home-based and school-based literacy activities, current home-based literacy activities and functions, and the interface of home-based family literacy practices and school-based literacy expectations. Ethnographic data offered insight into the understanding that literacy acquisition begins in the home and is dependent and reflective of literacy experiences that are sociocultural based. These home-based family literacy activities and functions are broad in scope and are valuable forms of literacy. However, these activities of marginalized families are often regarded as unimportant and/or unrelated to school-based literacy expectations, and therefore inferior. In response to this perceived mismatch between home-based family literacy activities and school-based literacy expectations, educators approached families from a deficit perspective. This deficit assumption created a sense of devalue on the part of the parents, who assisted their children by culturally and socially relevant means. To meet the school-based literacy expectations familial relationships were jeopardized as the pressure, frustration, and guilt from educators can result in emotional and physical abuse from mother to her children.

Condemned prisoners in Texas and most other states are given an opportunity to make a final statement in the last moments before death. An anecdotal review by the author of this study over the last 15 years indicates that condemned prisoners use the opportunity for a variety of purposes. They ask forgiveness, explain themselves, lash out at accusers, rail at the system, read poems, say goodbyes to friends and family, praise God, curse fate - and assert their innocence with their last breaths. The final words also are typically heard by a select group of witnesses, which may include a prisoner's family and friends, victim's relatives, and one or more journalists. What the public knows about a particular condemned person's statement largely depends on what the journalists who witness the executions chose to include in their accounts of executions, the accuracy of their notes, and the completeness of the statements that are recorded on departments of correction websites or records. This paper will examine, through rhetorical and content analyses, the final words of the 355 prisoners who were executed in Texas between 1976 and 2005, identify those who made unequivocal claims of innocence in their final statements, and analyze news …

Twelve-tone music illustrates many characteristics relative with those of conventional tonal form, though works are based on a different composition method. The fundamental question of twelve-tone music arises in debate on terminology between tonal and atonal as well as methodology of musical analysis. Certain theorists try to approach twelve-tone music by traditional harmonic views rather than by pitch-class set theory. Conventional harmonic aspects arise from the fact that both tonal and twelve-tone music share similar narrative strategies. This point is explored in examining Anton Webern's Quartet for Violin, Clarinet, Tenor-Saxophone and Piano, Op. 22, which displays connection to tonal music. The present study seeks to examine certain features of the composer's working in pitch materials; i.e., the dispositions of pitch classes and the characteristics of the matching dyads, and thereby to disclose the connection between twelve-tone methods and conventional harmony.

The purpose of this study was to determine the relationship between principals' leadership styles and principals'/teachers' implementation of technology. The Leadership Effectiveness and Adaptability Description (LEAD) Self was used to identify the primary and secondary leadership styles of principals. The Level of Technology Implementation (LoTi) Questionnaire was used to identify the level of technology implementation (LoTi), personal computer use (PCU) and current instructional practice (CIP) scores for both teachers and principals. Data collected from 390 K-12 teachers and 22 principals of three large suburban districts in the Dallas-Fort Worth Metroplex was included in data analysis. The findings suggest that differing leadership styles do play a role in the LoTi, PCU, and CIP scores among teachers. Based on descriptive statistics it was determined that teachers with "participating" principals had higher mean LoTi and PCU scores than those with "telling" and "selling" principals. The difference in the mean PCU scores was statistically significant (p<.05) for teachers with "selling" and "participating" principals. Results also showed there was a statistical significance (p<.05) in the mean PCU and CIP scores of teachers working for principals with weak and high adaptability. Due to the low number of principals participating in this study, there is a need …

I present strategies and methods for teaching fundamentals of music theory in the context of the private music studio through a variety of techniques and research. Beginning with a background in educational psychology, examples of behaviorist and cognitive teaching models are presented, and how each applies to teaching music is explained. Two detailed examples of actual lessons are presented, coupled with musical examples, to describe both the process and the concepts that can be presented. A qualitative experiment based upon the learning styles of three music students and the effect of different teaching styles when teaching the same concept is presented and discussed in detail.

This dissertation: (a) investigated the degree to which the squared canonical correlation coefficient is biased in multivariate nonnormal distributions and (b) identified formulae that adjust the squared canonical correlation coefficient (Rc2) such that it most closely approximates the true population effect under normal and nonnormal data conditions. Five conditions were manipulated in a fully-crossed design to determine the degree of bias associated with Rc2: distribution shape, variable sets, sample size to variable ratios, and within- and between-set correlations. Very few of the condition combinations produced acceptable amounts of bias in Rc2, but those that did were all found with first function results. The sample size to variable ratio (n:v)was determined to have the greatest impact on the bias associated with the Rc2 for the first, second, and third functions. The variable set condition also affected the accuracy of Rc2, but for the second and third functions only. The kurtosis levels of the marginal distributions (b2), and the between- and within-set correlations demonstrated little or no impact on the bias associated with Rc2. Therefore, it is recommended that researchers use n:v ratios of at least 10:1 in canonical analyses, although greater n:v ratios have the potential to produce even less bias. …

The purpose of this research is to empirically investigate consumers' health care decision choices in a dynamic market setting. The unprecedented demands on the U.S. health care system coupled with the mounting controversies surrounding health care reform suggest that consumers' health care decisions warrant empirical research attention. Toward this end, this dissertation empirically explored (1) the characteristics of consumers who possess a willingness to use non-conventional treatments over conventional treatments, (2) the characteristics of consumers who elect self-medication in lieu of health care practitioner-directed medication, and (3) the salient dimensions of consumers' channel choice for the procurement of health care products. Each of these decision choice factors were tested across two U.S. generational segments to assess whether differences existed across Baby Boomers' and Gen Yers' health care decision choices. The conceptual framework for empirical assessment is Bandura's (1986) social cognitive theory. From Bandura's social cognitive theory, a general model of healthcare decision choice is proposed to assess consumers' states of mind, states of being and states of action (decision choice). Results indicate that social cognitive factors (e.g., self-efficacy, objectivism) play an important role in each of the decision domains explored in this dissertation. Moreover, health value was found to be …

This study examined the distinct effects of partner violence and psychological abuse on women's mental health over time. Latent growth modeling was used to examine stability and change over time, evaluating the course and consequences of each form of abuse. The size of women's social support network was examined as a mediator. The sample consisted of 835 African American, Euro-American, and Mexican American low-income women. Participants who completed Waves 1, 2, 3, and 5 were included in the study (n = 585). In general, partner violence decreased over time for all groups, while psychological abuse decreased over time for only Euro-American women. Whereas initial and prolonged exposure to psychological abuse was related to and directly impacted women's mental health, partner violence was only related to initial levels of mental health. Surprisingly, social support was only related to initial violence and distress and had no impact on the rate of change over time. These results have important implications for researchers and health care professionals. First, differences in the pattern of results were found for each ethnic group, reaffirming the notion that counselors and researchers must be sensitive to multicultural concerns in both assessment and intervention. For example, psychological abuse had a …

Historians of the prohibition movement in Texas have assumed that the state's main ethnic minorities-Germans, Mexican Americans and African Americans-strongly opposed restrictions on the production, sale, and transportation of alcoholic beverages. This study focuses on the voting patterns in fifteen counties chosen to represent varying percentages of these ethnic minorities in their populations during three statewide anti-alcohol elections (1997, 1911, and 1919) in an effort to determine exactly the extent of opposition to prohibition on the part of ethnic minorities in Texas. It also examines the actions of the prohibitionists and anti-prohibitionists in courting the vote of ethnic minority groups. This analysis and comparison of election results in fifteen counties confirms overwhelming opposition to prohibition on the part of all three of Texas's ethnic minorities.

Vulnerable populations comprise a growing number of people living with HIV/AIDS and are at increased risk for poorer health outcomes. The purpose of this research was to approximate the effect of the Ryan White CARE Act on the health status of people living with HIV/AIDS who were receiving medical care in the United States. The vulnerable populations model was utilized to identify appropriate variables for analysis as well as to provide a sequencing for the testing of models. Data analyzed in this study came from the 1996 Baseline Survey of the HIV Cost and Services Utilization Study (HCSUS), a cooperative study between RAND and the Agency for Health Care Policy and Research (now known as the Agency for Health Care Quality and Research). Three analyses sequences, using different dependent variables, to estimate health status were conducted. In the first analysis, health status was measured by CD-4 count and stage of illness. In the second analysis, only CD-4 counts were used for health status. In the final analysis, health status was estimated based on AIDS diagnosis. Each of the three analyses included the same independent variables: race, gender, education, sexual orientation, income, insurance status, region of the country, receipt of case …

The purpose was to analyze Turkey's current music teacher training curriculum as situated in the centralized educational system, focusing on the extent to which the written document (1) reflects the core elements of the overall centralized educational system; (2) prescribes the nature of teaching materials and methods, assessment tools and other forms of evaluating and monitoring performance as teachers and musicians; and (3) acknowledges cultural diversity by addressing repertoire, musical activities and concepts according to geographic and cultural regions. Qualitative-descriptive and quantitative content analysis, including the methods of (a) Inverse document frequency and (b) relevance feedback model, were the analytic tools. Of the required 147 credit hours, 138 are the core. The music core consists of 87 (63%) and the non-music core of 51 credit hours (37%). On paper, there is a conceptual overlap in wording between the music core, the general core, and the teacher training core, suggesting curricular cohesion and consistency. Noticeably less cohesion exists between the document and three major policy papers on teacher competencies. By word count, preparing teachers for instruction in Turkish folk music and multicultural issues appears to hold a low priority in the curriculum. However, course descriptions, where they exist, speak to skills …

The purposes of the study were to: 1) identify the underlying dimensions of consumer shopping motivations and attitudes toward online auction behaviors; 2) examine the relationships between shopping motivations and online auction behaviors; and 3) examine the relationships between shopping attitudes and online auction behaviors. Students (N = 341) enrolled at the University of North Texas completed self-administered questionnaires measuring shopping motivations, attitudes, online auction behaviors, and demographic characteristics. Using multiple regression analyses to test the hypothesized relationships, shopping motivations and shopping attitudes were significantly related to online auction behaviors. Understanding the relationships is beneficial for companies that seek to retain customers and increase their sales through online auction.

With three homogenous caregiver groups (i.e., Alzheimer's caregivers, grandparents raising grandchildren, parents), caregiving styles were explored to determine their reliability and validity, their unique role in predicting caregiver outcomes, and their differences between groups of caregivers. A conceptual framework was adapted to determine the impact of contextual variables, caregiving styles, caregiver appraisal, and mediating variables on caregiving outcomes. A more concise version of the Caregiving Style Scale (CSS) was developed with 49 items yielding an internal consistency coefficient of .74. As expected, three caregiving styles emerged and were positively related to the parallel parenting styles. Across the caregiver samples, there were positive relationships among caregiving style dimensions within the same caregiving style, while those from opposing caregiving styles tended to have negative relationships indicating good convergent and discriminant validity. Authoritative caregiving style dimensions were generally associated with healthier functioning, while authoritarian and permissive caregiving style dimensions were correlated with less healthy functioning. Caregiving style dimensions were among the predictors of several outcome measures, highlighting the importance of their placement in the conceptual framework for caregiver stress and coping. Generally, an unexpected finding was that authoritative caregiving style dimensions tended to predict less adaptive caregiving outcomes, particularly for parents and grandparents, …

The effects of cranial electrotherapy stimulation (CES) on human EEG and brain current density were evaluated by quantitative electroencephalography (qEEG) and low resolution brain electromagnetic tomography (LORETA). A total of 72 research subjects were provided with a single session of CES, 38 were provided with 0.5 Hz CES while 34 were provided with 100 Hz CES. The qEEG paired t-tests revealed that in both frequencies of CES there was a significant (.05) increase in alpha relative power with concomitant decreases in delta and beta relative power. The 0.5 Hz CES decreased a wider frequency range of delta activity, while the 100 Hz CES decreased a wider frequency range of beta activity; suggesting some difference may exist in the EEG response to different frequencies of CES. The changes found in qEEG relative power were consistent with the affective and cognitive effects of CES reported in the literature, such as increased relaxation and decreased anxiety. Statistically significant changes for qEEG values other than relative power, such as coherence, amplitude asymmetry, phase lag and power ratios were also found. The LORETA paired t-tests found statistically significant (.05) increases in cortical and subcortical theta and alpha frequency current density with concomitant decreases in delta …

The current study investigates whether there are there ethnic differences between Caucasian, African American, and Hispanic women in (a) weight bias, (b) body ideals, (c) social awareness and internalization of appearance standards and (d) physical activity in relation to these constructs. Participants included 130 Caucasian, 103 African American, and 52 Hispanic undergraduate female students. Participants completed a demographic survey, the Antifat Attitudes Test, the Figure Rating Scale, the Sociocultural Attitudes toward Appearance Questionnaire, and the Multiethnic Identity Measure questionnaire. No significant ethnic group differences in weight bias emerged. Differences were found for participants' perceptions of the culturally ideal female body shape, as well as awareness and internalization. No relationship was found between physical activity and weight bias, body ideals, and appearance standards. Future researchers should use health weight classifications, in addition to ethnicity, to examine weight bias, body ideals, and physical activity.

This study examined, via a meta-analysis, the relations among stressors, social support, and stress reactions. Unexpectedly, small to medium negative, but robust effect sizes were found for the stressors-social support relation. As expected the stressor-stress reaction relation was positive, and the social support-stress reaction relation was negative. Both relations had small to medium effect sizes that ranged from weak to very robust. The direct effect of social support on the stressor-stress reaction was generally supported, whereas the suppressor and mediating models were not supported. Furthermore, the findings were inconclusive for the moderator effect of social support. Non-interpersonal traumas appear different in the stressor-social support and social support-stress reaction relations compared to other trauma types. These findings have important clinical implications.

Many critics consider Mariama Bâ as a feminist writer, but the reader of her two novels might wonder what characterizes her work as such. Therefore, the aim of each chapter, in order of appearance, is to analyze first the genres, then the elements of African tradition and Western modernity, the characters of both works and the themes of the novels, with the intention of defining the author's feminism, which takes its source in dichotomies, paradoxes and contradictions. In order to expose the author's point of view on the condition of women, it appears important to situate the diegesis in its context. Also, the study is supported by references on the Senegalese culture, by genres, narrative and feminist theories and by critiques on the work itself.

Public school per pupil costs and demands for better performance have increased over the past several decades. While the overall per pupil expenditures have increased, the percent of the educational dollar directed toward instructional activities has remained at approximately 60%. A grass-roots movement known as the "65% Solution" caught national attention by claiming that schools are not efficiently allocating resources into areas that have the greatest link to student achievement, such as instruction. Proponents of the 65% Solution claim that per pupil expenditures can be increased by shifting funds from areas considered non-instructional to areas that directly impact student instruction, such as teachers and instructional materials. The purpose of this study was to determine the relationship between district Panel Recommended and Commended Performance TAKS Reading/ELA and Math results and three measurements of instructional expenditures, Instructional Staff Percent; TEA Instructional Expenditure Ratio; and the NCES Instructional Expenditure Ratio (65% Solution), in Texas public schools. Data was collected from the 2003-2004 AEIS report. Multiple regression was used to conduct the analyses. In most instances, there was little, if any, relationship between TAKS Reading/ELA and TAKS Math, and the Instructional Staff Percent (ISP), TEA Instructional Expenditure Ratio (TIER), and NCES Instructional Expenditure Ratio …
