First generation college students face some unique challenges in the pursuit of higher education. Aside from academic stressors, there are stressors related to social and cultural transitions which may exacerbate pre-existing emotional or psychological distress. Research suggests that acculturation influences psychological well-being and development. The current study examined the relationships between acculturation, acculturative stress, socio-economic status, and symptoms of anxiety among first-generation college students of Hispanic origin. Participants (N = 125) included those who were first in their family to attend college and were primarily female, of traditional college age, and of Mexican heritage. All measures were self-report and were completed online. Overall, this study was inconclusive as most analyses were underpowered. The present study failed to support a relationship between style of acculturation and symptoms of anxiety, although, experiencing Anglo marginality was related to high levels of acculturative stress and anxiety. Finally, regression analysis revealed that acculturative stress, age, and Anglo marginalization were significant predictors of anxiety and accounted for 31% of variance in anxiety. Implications of the present study were discussed. Further study with adequate power is highly recommended.

This research is a descriptive analysis answering the question, what measures are currently taken by the leadership―boards of trustees and superintendents of schools―of Texas school districts to prevent embezzlement? The research perspective utilized was quantitative with a descriptive, cross-sectional design. Data collection was accomplished through a survey with questions constructed from the most commonly recommended strategies discovered through the review of literature. The survey was distributed to the 1031 superintendents of school districts in Texas via email. The response rate was 33% or 339 returned surveys. The data set created concentrates on the four most common preventive measures: policy and procedure, management, auditing, and ethics. These measures are considered as they function to interrupt the principles of the fraud triangle. Comparisons were completed regarding region, district size, superintendent tenure and superintendent experience. Policy adoption was found to be extremely widespread. Procedures written to fully implement policy were less prevalent. Review of management practices found problems concerning credit cards, personnel evaluations, and password access to multiple computer finance recordkeeping systems concentrated in one employee. External auditing programs were universal due to statutory mandate but internal auditors and internal audit committees were few. Ethics training for business office personnel existed but with …

Mahler's Ninth Symphony, since its premier in 1912, has sparked much debate about its programmatic meaning. This thesis provides an in-depth analysis of the Adagio and an examination of the controversy of the farewell story. In the process of the analysis I have compared my findings to some of the important authors in Mahler's field such as Vera Micznik, Henry-Louis de La Grange, and Christopher Orlo Lewis. Some of the conclusions are that a closer investigation of the music is necessary and that the programmatic reading of the farewell story can be appropriate.

Alfredo Casella's Serenata, op. 46 for clarinet, bassoon, trumpet, violin and cello is a composition that received great acclaim at the time of its conception, it is all but unknown to modern audiences and performers. The Serenata has several historical influences from the French and Italian Baroque and Classical periods. At present, there is limited scholarship regarding the Serenata op. 46. The first section of this study presents a survey of historical information, current literature and methods of examination. The second section compares movements of the Serenata op. 46 to other historical forms of similar design. The third section provides a performance guide for the trumpeter and ensemble. Implications and suggestions for performance of the composition are provided for the trumpeter. This performance guide provides the trumpeter and ensemble with performance information to help facilitate an informed performance.

Let G be a Polish group. We say that G is an algebraically determined Polish group if given any Polish group L and any algebraic isomorphism from L to G, then the algebraic isomorphism is a topological isomorphism. We will prove a general theorem that gives useful sufficient conditions for a semidirect product of two Polish groups to be algebraically determined. This will smooth the way for the proofs for some special groups. For example, let H be a separable Hilbert space and let G be a subset of the unitary group U(H) acting transitively on the unit sphere. Assume that -I in G and G is a Polish topological group in some topology such that H x G to H, (x,U) to U(x) is continuous, then H x G is a Polish topological group. Hence H x G is an algebraically determined Polish group. In addition, we apply the above the above result on the unitary group U(A) of a separable irreducible C*-algebra A with identity acting transitively on the unit sphere in a separable Hilbert space H and proved that the natural semidirect product H x U(A) is an algebraically determined Polish group. A similar theorem is true …

Four Rotations Pour Marimba (1996) by Eric Sammut has become one of the most important marimba compositions in serious concert solo marimba literature. Four Rotations Pour Marimba is a suite of four short pieces; each of them demonstrates a different musical character while incorporating similar compositional components and techniques. The goal of this thesis project is to create a stylistic analysis for providing the concert marimbist with insight into the interpretation of these four pieces and also giving composers a more in-depth understanding of Sammut's compositional method. This thesis includes a formal analysis and comparisons of compositional elements used in Four Rotations. A brief biography of Sammut and historical significance of Four Rotations Pour Marimba are also included.

C. halicacabum (Sapindaceae) is an invasive plant that is considered a nuisance species in Texas riparian environments. Little is known of the tolerance of C. halicacabum to flooding and drought; however, this information may provide insight into the characteristics that contribute to C. halicacabum purported invasiveness. C. halicacabum seedlings (n = 92) were exposed to one of four levels of water availability (flooded, saturated, intermediate and dry) over six weeks under greenhouse conditions. Plant performance was affected by water availability; however, there was no effect on survivorship. Flooded and saturated plants exhibited morphological adaptations; producing adventitious roots, hypertrophy, and aerenchyma tissue. Morphological measures, anatomical responses, and patterns of biomass allocation all indicate that C. halicacabum is able to survive periodic inundation, perform in saturation, and establish and thrive on the drier end of a moisture gradient.

Alkali-silica reaction (ASR) in cement is a major contributor to failure of cement structures around the world, causing increased repair costs and possible rebuild expenses. Alkali levels are indicative of the potential for ASR and are therefore measured and quantified. A linear correlation relating cement alkali concentration measured by X-ray fluorescence spectroscopy (XRF) and peak ratio measured by Fourier transform infrared spectroscopy (FTIR) is developed. Regression analysis of plots correlating alkali content measured by FTIR absorption band (750 cm-1/923 cm-1) ratio versus equivalent alkali (Na2O)e (%Na2O + 0.658 % K2O) quantified by XRF show linear correlation coefficient, R2, of 0.97. Results of this investigation are discussed in terms of microstructural disorder coefficient Cd which is a reactivity criterion for ASR-susceptible aggregates proposed by Bachiorrini [31]. XRF is a popular technique for alkali quantification but FTIR is faster, safer, and less expensive technique compared to XRF. Portable instrumentation is available for both techniques but FTIR systems are less expensive.

Currently, only the TSI assesses complex traumatic reactions and patient response styles. However, its feigning scale, ATR, uses a flawed detection strategy and is potentially confounded by experiences of complex PTSD. As a consequence, clinicians using the TSI to evaluate severely traumatized patients have no useful method for discriminating genuine and feigned responding. Several detection strategies have demonstrated utility within evaluations of feigned trauma including the assessment of rare symptoms, symptom combinations, symptom selectivity, and symptom severity. The current study created scales on the TSI according to these strategies using a development sample of 107 severely traumatized patients. Validation of all TSI feigning scales was then performed with a second independent sample of 71 severely traumatized patients using a mixed simulation design. Results found support for each scale's convergent validity with SIRS primary scales (M rs = .52) and discriminant validity with measures of defensiveness on the SIRS (M rs = -.07) and TSI (M rs = -.19). Each scale also produced expectedly mild to moderate relationships with SADS-C clinical scales (M rs = .32) and the SCID-IV PTSD module (M rs = -.02). Support for their criterion validity was only moderate (M ds = .69) when comparing the scores …

In today’s fast paced world, as the number of stations of television programming offered is increasing rapidly, time accessible to watch them remains same or decreasing. Sports videos are typically lengthy and they appeal to a massive crowd. Though sports video is lengthy, most of the viewer’s desire to watch specific segments of the video which are fascinating, like a home-run in a baseball or goal in soccer i.e., users prefer to watch highlights to save time. When associated to the entire span of the video, these segments form only a minor share. Hence these videos need to be summarized for effective presentation and data management. This thesis explores the ability to extract highlights automatically using MPEG-7 features and hidden Markov model (HMM), so that viewing time can be reduced. Video is first segmented into scene shots, in which the detection of the shot is the fundamental task. After the video is segmented into shots, extraction of key frames allows a suitable representation of the whole shot. Feature extraction is crucial processing step in the classification, video indexing and retrieval system. Frame features such as color, motion, texture, edges are extracted from the key frames. A baseball highlight contains certain …

The most effective and useful way to diagnose and subtype depression has been a long debated topic which even now does not have a definite answer. The biopsychosocial approach to diagnosis may be a solution to this problem by linking various etiologies to symptom presentation. The biopsychosocial model, in regard to depression, takes into account biological risk factors/contributors, psychological or cognitive risk factors/contributors, and social risk factors/contributors to depression when making diagnosis and subtyping determinations. However, the most effective way to use this model in the assessment, diagnosis, and treatment of depression is not yet clear. In this study, the utility of the biopsychosocial model as an effective approach to conceptualizing and treating depression was assessed by testing hypotheses that showed that etiological contributors are related to the presence and differential presentation of depression, and that these etiologically-based subtypes of depression respond differently to different forms of treatment. These hypotheses were tested using data from the National Comorbidity Survey - Replication (NCS-R). Results showed that the biopsychosocial model can effectively predict the presence, severity and chronicity of depression, and may inform specific biopsychosocially-based subtypes. No conclusions could be drawn regarding success in treatment based on the biopsychosocial model. Future directions …

Tissue engineering merges the disciplines of study like cell biology, materials science, engineering and surgery to enable growth of new living tissues on scaffolding constructed from implanted polymeric materials. One of the most important aspects of tissue engineering related to material science is design of the polymer scaffolds. The polymer scaffolds needs to have some specific mechanical strength over certain period of time. In this work bioresorbable aliphatic polymers (PCL and PLLA) were blended using extrusion and solution methods. These blends were then extruded and electrospun into fibers. The fibers were then subjected to FDA standard in vitro immersion degradation tests where its mechanical strength, water absorption, weight loss were observed during the eight weeks. The results indicate that the mechanical strength and rate of degradation can be tailored by changing the ratio of PCL and PLLA in the blend. Processing influences these parameters, with the loss of mechanical strength and rate of degradation being higher in electrospun fibers compared to those extruded. A second effort in this thesis addressed the potential separation of the scaffold from the tissue (loss of apposition) due to the differences in their low strain responses. This hypothesis that using knit with low tension will …

This documentary film explores the damages produced by the illegal dumping of toxic waste in the environment and the rise in health concerns specific to the Campania region in Southern Italy. The management of waste material in the region is in the hands of the Camorra - a mafia organization with vast economic and political power. Through the narration of personal stories, the documentary reveals the broken emotional and cultural balance between the people from the region and their land.

Translation and subtitling has always been a complicated dimension of the motion picture industry for years. The problem of dealing with linguistic elements in films and conveying them to audiences of different languages across the globe encompasses many difficulties regarding forms and structures of other languages. One of the more highly researched topics in French linguistic studies has been the use of address pronouns and a range of aspects related to their use and interpretation. Many studies have been conducted over the last sixty years in order to determine and understand these variables. An analysis of several of these studies reveals the many complexities involved in second-person pronoun choice in the French language and the development of the idea of pronoun choice as an act of social identity. The focus of this study is to provide an analysis of the use of formal and informal address pronoun use in the French subtitling and dubbing of an American film, Maid in Manhattan, in order to add, on a broader level, a way to differentially examine perceived norms in a variety of contexts within this medium.

State officials, between 1882 and 1888, exchanged three million acres of Texas Panhandle property for construction of the monumental Capitol that continues to house Texas government today. The project and the land went to a Chicago syndicate led by men influential in business and politics. The red granite Austin State House is a recognizable symbol of Texas around the world. So too, the massive tract given in exchange for the building, what became the "fabulous" XIT Ranch, also has come to symbolize the height of the nineteenth century cattle industry. That eastern and foreign capital dominated the cattle business during this period is lesser known, absorbed by the mythology built around the Texas cattle-trail period - all but at an end in 1885. This study examines the interaction of Illinois Republicans and Texas Democrats in their actions and efforts to create what have become two of Texas's most treasured symbols.

Predictive methods have been employed to characterize chemical separation mediums including solvents and absorbents. These studies included creating Abraham solvation parameter models for room-temperature ionic liquids (RTILs) utilizing novel ion-specific and group contribution methodologies, polydimethyl siloxane (PDMS) utilizing standard methodology, and the micelles cetyltrimethylammonium bromide (CTAB) and sodium dodecylsulfate (SDS) utilizing a combined experimental setup methodology with indicator variables. These predictive models allows for the characterization of both standard and new chemicals for use in chemical separations including gas chromatography (GC), solid phase microextraction (SPME), and micellar electrokinetic chromatography (MEKC). Gas-to-RTIL and water-to-RTIL predictive models were created with a standard deviation of 0.112 and 0.139 log units, respectively, for the ion-specific model and with a standard deviation of 0.155 and 0.177 log units, respectively, for the group contribution fragment method. Enthalpy of solvation for solutes dissolved into ionic liquids predictive models were created with ion-specific coefficients to within standard deviations of 1.7 kJ/mol. These models allow for the characterization of studied ionic liquids as well as prediction of solute-solvent properties of previously unstudied ionic liquids. Predictive models were created for the logarithm of solute's gas-to-fiber sorption and water-to-fiber sorption coefficient for polydimethyl siloxane for wet and dry conditions. These models …

In the last decade emerging contaminants research has intensified in a bid to answer questions about fate, transport, and effects as these chemicals as they get released into the environment. The chemicals of interest were the antimicrobials; triclocarban (TCC) and triclosan (TCS), and a metabolite of triclosan, methyl triclosan (MTCS). This research was designed to answer the question: what is the fate of these chemicals once they are released from the waste water treatment plant into receiving streams. Three different assessment methods; field monitoring, in-situ experiments, and laboratory studies were used to answer the overall question. TCS, TCC, and MTCS levels were measured in surface water, sediment and the Asiatic clam Corbicula fluminea. Field studies were conducted using four sites at Pecan Creek, Denton TX. Levels of all three chemicals in clams were up to fives orders of magnitude the water concentrations but an order of magnitude lower than in sediment. Highest sediment levels of chemicals were measured in samples from the mouth of Pecan Creek (highest organic matter). TCC was the most and TCS was the least accumulated chemicals. In-situ and lab studies both indicated that uptake of these chemicals into the clams was very rapid and measurable within …

While the proliferation of literature on the subject of growing incivility in society demonstrates the increasing importance given to civility by corporate America, there has been little academic investigation of the concept. The limited number of academic studies on civility reveals immense negative consequences for uncivil behavior. One question for marketers of businesses is whether lack of civility among front-end personnel can negatively influence sales. This dissertation is an attempt to fill this research gap by exploring responses to uncivil behavior under the theoretical framework of attribution theory. Using the CDSII scale based on attribution theory, experimental research design was used with current civil and uncivil behavior by the store employees and past experiences (positive, negative, and no-experience) with the store as stimulus. The consumers' perception of civility, attributions and behavioral intentions were measured and used as dependent variables. The results of the experiment showed that when a customer discerns employee behavior to be uncivil, the customer's perception of the level of the ability of the employee to control his own behavior decreases. The results of the study enhance the knowledge of two important consumer behaviors, namely complaining and switching behaviors by empirically studying their antecedents in a particular market …

In this thesis, I present my study on the impact of multi-group network structure on the performance of consensus building strategies, and the preliminary mathematical formulation of the problem on improving the performance of the National Airspace system (NAS) through long-term investment. The first part of the thesis is concerned with a structural approach to the consensus building problem in multi-group distributed sensor networks (DSNs) that can be represented by bipartite graph. Direct inference of the convergence behavior of consensus strategies from multi-group DSN structure is one of the contributions of this thesis. The insights gained from the analysis facilitate the design and development of DSNs that meet specific performance criteria. The other part of the thesis is concerned with long-term planning and development of the NAS at a network level, by formulating the planning problem as a resource allocation problem for a flow network. The network-level model viewpoint on NAS planning and development will give insight to the structure of future NAS and will allow evaluation of various paradigms for the planning problem.

The present meta-analytic study estimated the overall effectiveness of child therapy interventions using CCPT methodology and explored the relationships between study characteristics and treatment effects. Fifty-two studies between 1995 and the present were included based on the following criteria: (a) the use of CCPT methodology, (b) the use of control or comparison repeated measure design, (c) the use of standardized psychometric assessment, and (d) clear reports of effect sizes or sufficient information for effect size calculation. Hierarchical linear modeling (HLM) techniques were utilized to estimate the overall effect size for the collected studies and explore relationships between effect sizes and study characteristics. Dependent variable included 239 effect sizes, and independent variables included 22 study characteristics. The mean age of all child participants in the collected studies was 6.7. In 15 studies, the majority of participants were Caucasian. An equal number of studies were made up of non-Caucasian participants, including 3 with majority African American, 4 with majority Hispanic/Latino participants, 5 with majority Asian/Asian American participants, and 3 with other ethnic populations. Study collection included 33 studies with majority of boys and 11 studies with majority of girls. HLM analysis estimated a statistically significant overall effect size of 0.47 for the …

This paper examines the use of infinitival and gerundial constructions by intermediate Spanish learners. The use of those two patterns creates problems for second language learners at intermediate and advanced levels. However, there are only few studies on their second language acquisition, and fewer focus on Spanish learners. This study tries to resolve this and to this end, I retrieved all hits of the two constructions from the Spanish component of the International Learner Corpus of English (SP-ICLE). I run a distinctive collexeme analysis (DCA) to identify the verbs that are associated with either pattern. The results are discussed at three different levels: (i) the identification of verbs that Spanish learners associate with each construction; (ii) a systematic comparison with previous studies on native speakers to show possible similarities/discrepancies; and (iii) a comparison of the results with findings on German learners to discuss possible effects of language similarity and transfer.

The completion of the dissertation certifies the completion of the academic rigors of the doctoral degree and verifies the candidate's achievement of independent scholarship. The Carnegie Project on the Education Doctorate was a 5-year effort to define the distinct purpose of the Ph.D. and Ed.D. in education. The Carnegie Project sought to ensure that the academy moved forward on two fronts: rethinking and reclaiming the research doctorate, the Ph.D., and developing the distinct professional practice doctorate, the Ed.D. The project determined that there has been a blurring of the distinctions between these two degrees over the past half-century which invites examination of their purpose and their content. Given this, this qualitative study examined Ph.D. and Ed.D. dissertation abstracts to determine if abstracts differ in terms of these selected factors: research design, data analysis, use of theoretical frameworks, subjects or participants, the setting or context of the study, and to compare Ph.D. and Ed.D. abstracts to the abstract format recommended in literature to explore if there are differences in the abstracts and to determine to what extent abstracts in either degree are congruent with the recommendations. This study used a digital dissertation database to study 100 Ed.D. dissertation abstracts and 100 …
