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 little consistent application across districts. The adoption of a code of ethics for business office personnel was rare. Recommendations made were that school leaders should be educated concerning appropriate actions in the common prevention areas. They need an to understand the importance of internal auditing, know the language in local policy, and they need to write procedures.
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 for the natural semidirect product R^{n} x G(n), where G(n) = GL(n,R), or GL^{+}(n,R), or SL(n,R), or |SL(n,R)|={A in GL(n,R) : |det(A)|=1}. On the other hand, it is known that the Heisenberg group H_{3}(R) , (R, +), (R{0}, x), and GL^{+}(n,R) are not algebraically determined Polish groups.
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 of genuine patients to those simulating disability. Potential explanations for this trend were reviewed, including (a) the impact of comorbidity, (b) the restrictions associated with creating embedded feigning scales, and (c) the influence of simulator knowledge in analogue designs. Limitations of the study and future avenues of research were discussed.
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 types of scene shots and these shots follow a particular transition pattern. The shots are classified as close-up, out-field, base and audience. I first try to identify the type of the shot using low level features extracted from the key frames of each shot. For the identification of the highlight I use the hidden Markov model using the transition pattern of the shots in time domain. Experimental results suggest that with reasonable accuracy highlights can be extracted from the video.

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 for research based on the current study are discussed.
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 have better compliance was tested and confirmed.
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 were created to standard deviations of 0.198 and 0.122 logunits for gas-to-PDMS wet and dry, respectively, as well as 0.164 and 0.134 log units for water-to-PDMS wet and dry, respectively. These models are particularly useful in solid phase microextraction separations. Micelles were studied to create predictive models of the measured micelle-water partition coefficient as well as models of measured MEKC chromatographic retention factors for CTAB and SDS. The resultant predictive models were created with standard deviations of 0.190 log units for the logarithm of the mole fraction concentration of water-to-CTAB, 0.171 log units for the combined logarithms of both the …
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 24hours of exposure. The after clams were transferred into clean water most of the compounds were depurated within 14 days.
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 interaction context. The results imply that it is important to eliminate or minimize any experience that the customer may construe as negative at a store. If practitioners can work towards eliminating or decreasing certain attributions of consumers, they can reduce the switching behaviors and thus impact customer retention rates and future sales. Though this study contributes to marketing theory and provides vital insights to practitioners, this study is but a starting point for further examination of the role of civility in consumer behavior and decision making.
This study is focused on an analysis of two single-subject ricercare in the keyboard music of Johann Jacob Froberger and examines possible pathways to the development of the Baroque fugue. This dissertation is divided into three parts. Chapter I contains the purpose, significance of this study and composer, as well as characteristics of the seventeenth-century single-subject ricercar. Chapter II details and examines Froberger's two ricercare. Finally, a conclusion of this study is presented in Chapter III. Two appendixes are included in this dissertation: a list of the single-subject ricercare of Andrea Gabrieli, Giovanni Gabrieli, and Johann Jacob Froberger; and an analysis of the two single-subject ricercare, FbWV 407 and FbWV 409, by Johann Jacob Froberger.
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 collected studies (p < 0.001). This result indicated that the overall improvement from pre to post treatment demonstrated by children in experimental groups was approximately 1/2 standard deviation better than by children in control groups. A statistically significant amount (49.2%) of between-study variance was found (p < 0.001), indicating the heterogeneity among the 52 studies Statistically significant relationships were found between effect sizes and study characteristics including child age, child ethnicity, clinical level of referral, treatment integrity, presenting issue, source of data, population, and caregiver involvement. Effect size findings for CCPT and its moderators should be interpreted in light of …
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 Ph.D. dissertation abstracts on the topic of higher education. The design was qualitative and used a frequency of terms and an accepted understanding of concepts between two researchers to reach a conclusion regarding the contents of the abstracts. Two researchers separately coded a selection of dissertations for each degree to establish an acceptable level of credibility for the coding of the abstracts. Multiple findings describe similarities and differences between these two degrees and the extent of the convergence of Ed.D. and Ph.D. abstracts with recommended abstract components in the literature. The study concludes that many dissertations do not include all …
This collection consists of a critical preface and five linked short stories. The preface analyzes the usage of violence in literate and other forms of media, and specifically the ways in which literature can address violence without aggrandizing or stylizing it. The stories explore this idea through the lens of the lives of two young men, following them from boyhood marked by violence to adulthood crushed by the trauma of the American Civil War. Collection includes the stories "Dead Foxes," "Cow Pen," "Fatherless," "Woodsmoke," and "Brotherhood."
The mobility, flexibility, convenience, and ubiquity of mobile data services (MDS) have contributed to their enormous growth and popularity with users. MDS allow users to communicate through mobile texting (mTexting), mobile Instant Messaging (mIM), multimedia messaging services (MMS), and email. A unique feature of MDS that enhances its popularity among its users is the awareness capability, which is revolutionizing the way MDS is being used to communicate today. It allows potential communication partners to socialize through these technologies. This dissertation explored the relationship between user experience, perceived richness, perceived social presence and satisfaction with MDS. A research model for examining the antecedent conditions that influence social presence, richness, social interaction and satisfaction with MDS was developed. Partial least square analysis showed that user experience influenced both social presence and richness. Also supported was the relationship between richness, social presence and satisfaction with MDS. Social presence mediated the relationship between user experience and richness. However, only one dimension of interactivity influenced social presence.
Within this educational endeavor instrumental development was explored through the investigation of microwave induce stable electromagnetic waves within a non-linear yttrium iron garnet ferromagnetic waveguide. The resulting magnetostatic surface waves were investigated as a possible method of rapid analytical evaluation of material composition. Initial analytical results indicate that the interaction seen between wave and material electric and magnetic fields will allow phase coherence recovery andanalysis leading to enhancement of analytical value. The ferromagnetic waveguide selected for this research was a high quality monocrystalline YIG (yttrium iron garnet) film. Magnetostatic spin waves (MSW) were produced within the YIG thin waveguide. Spin waves with desired character were used to analytically scan materials within the liquid and solid phase.
Through the partnership of standpoint theory and photovoice method, the present study looked at how teenagers, attending a multicultural education camp, define diversity, as well as what the participants considered to be the benefits and limitations of diversity. Standpoint theory gives the theoretical perspective to understand the marginalized voice of teenagers, while photovoice provides the tools to better capture and understand their marginalized voice. This study was situated in a professionally-developed camp, Camp CommUNITY, that emphasizes multicultural awareness amongst teens. Nine participants and 46 pictures were analyzed. Resulting from open coding, 11 categories and 6 themes were identified. Each theme and definitions of diversity are approached with a dialectical perspective, yielding to the model of dialectical dimensions of diversity. To answer Research Question 2, participants identified both benefits and limitations for photovoice method. Additional theoretical, practical, and methodological implications, limitations, and directions for future research are addressed.
American composer Jake Heggie's For a Look or a Touch exists as the only classical music work of remembrance based on the topic of remembering homosexual victims of the Holocaust. The composer, after being approached by Mina Miller, wrote this 2007 composition as part of the Music of Remembrance concert series. The music of this work varies in style from a blazing swing dance to a haunting vocalise on "oo." Gene Scheer created the text, delivered in the work by the characters Manfred Lewin and Gad Beck, as a compilation of many influential stories from the documentary film Paragraph 175. For a Look or a Touch chronicles the horrendous treatment of homosexuals before, during, and after World War II. Chapters include an introduction to homosexual persecution during Hitler's reign, a look at current works of remembrance and how For a Look or a Touch came to fruition, an explanation of the texts created by Gene Scheer, a discussion on Jake Heggie's musical setting of this text, and avenues for possible future research. Appendices include text of the German anti-sodomy laws as written in Paragraph 175, the mission statement for the organization Music of Remembrance, transcripts from personal interviews with both Jake Heggie and Gene Scheer, correspondence with Heggie, and the source delineation of Gene Scheer's text.
This quantitative study utilized secondary data furnished by 652 institutions of higher education which participated in the 2008 Voluntary Support of Education (VSE) national study managed by the Council for Aid to Education. This study investigated the relationships among private and public status across baccalaureate, masters and doctoral degree typologies and total alumni giving, restricted giving and unrestricted giving per full time equivalent (FTE) for the 2007/08 academic year. The independent variable included the three degree-granting sub-categories of institution as categorized by either public or private status. The dependent variables included total computed alumni giving for 2008 per FTE, restricted alumni giving for 2008 per FTE and unrestricted giving by alumni for 2008 per FTE. ANOVA main effects were calculated and statistical significance determined using the α < .05 level. Tukey Post-Hoc calculations were computed and Cohen's f 2 was used to determine effect sizes. Total alumni giving per student FTE differed at statistical significance across the six institution types, F (5, 651) = 37.181, p < .001, f 2 = .29. Total restricted giving per student FTE differed at statistical significance across the six types, F (5, 651) = 28.90, p < .001, f 2 = .22. Total unrestricted giving per student FTE differed at statistical significance across the six types, F (5, 651) = 35.371, p < .001, f 2 = .27. This study's restricted giving index documents alumni make differentiated choices concerning gifts based on institution type. Recommendations are issued for further research and professional practice.
Dream of a Thousand Keys is a concerto for piano and orchestra, which consists of four movements presenting multiple dimensional meanings as suggested by the word "key." I trace the derivation of Korean traditional rhythmic cycles and numerical sequences, such as the Fibonacci series, that are used throughout the work, and explore the significant role of space between the soloist and piano that are emphasized in a theatrical aspect of the composition. The essay addresses the question of musical contrasts, similarities, and metamorphosis. Lastly, I cover terms and concepts of significant 21st-century compositional techniques that come into play in the analysis of this work.
This research examined whether or not relationships exist between preschool teacher quality and parent involvement as indicated by the Hoover-Dempsey and Sandler Model of Parent Involvement Survey. Additionally, the study also considered family income and child membership in special education as predictors of parent involvement. The survey instruments included the Early Childhood Environmental Rating Scale, Revised (ECERS-R) and the Hoover-Dempsey and Sandler Parent Involvement Survey. A total of 306 parents across 35 preschool classrooms participated in the study. Effect sizes, beta weights and structure coefficients from a series of multiple regression analyses measured the relationship between variables. A regression equation comprised of teacher quality, family income and child membership in special education was statistically significant in predicting parent school-based involvement. In the school-based involvement model the predictors teacher quality and child membership in special education accounted for a greater percentage of variance than did family income. Teacher quality demonstrated a small, negative beta weight but accounted for the greatest amount of variance among the three predictors within the school-based parent involvement model. A negative relationship between teacher quality and school-based parent involvement suggested that as teacher quality improved, parents reported less involvement in school-based activities and events. Findings for special education membership, however, demonstrated a reverse effect in the model and appeared to have a positive significant effect on school-based involvement of parents. The study contributes to the literature on the relationship between teacher quality and parent involvement in early childhood preschool programs.
This dissertation has two overall objectives: first, to demonstrate the utility of paleozoological data for ongoing and future mussel-conservation efforts in Texas and second, to evaluate whether simple measures of habitat (e.g., water depth, velocity and particle size) are important for demonstrating the within-habitat spatial separation of mussels. Although these topics may seem disparate, both are important for increasing our understanding of unionid ecology and biogeography. Chapters 1 through 3 examine the use of paleozoological data for mussel conservation. Although these types of data are not new they have rarely been used in mussel conservation efforts within Texas. This is unfortunate because paleozoological data can provide an excellent record of the mussel fauna prior to wide-scale modern impacts and in areas where historical survey data are lacking. Chapter 4 examines whether assessments of microhabitat for mussels using simple measures of habitat (e.g., water velocity, depth and particle size) are useful. Recent studies have suggested that these measures do not explain the mussel distribution in flowing streams. If this is correct, instream flow studies using this approach need to be revised. Results of Chapter 4 indicate that mussels in the lower Brazos River basin are constrained in distribution by the availability of heterogenous substrate. Appendix A, details the first account of a living population of Truncilla macrodon, which is a candidate species for the Endangered Species Act (ESA). The population was found while conducting mussel instream flow studies in the lower Brazos River basin.
The aim of the current study was to examine how thinking about qualitatively different social network members may differentially affect cardiovascular reactivity to a subsequent stressor. Eighty-two undergraduates were asked to think and write about different types of relationships preceding a social stressor. No differences between conditions in CVR were found during social support induction phase or the stressor task. Women in the supportive condition were found to have slower SV recovery than those in the ambivalent condition. The results of this study are inconsistent with previous evidence for a relationship between mental representations of social ties and CVR. Future research should seek to rule out confounding variables and clarify this effect.
A growing disparity between the mental health needs of children and their lack of treatment served as the basis of this study. To address this existent gap, I proposed that child-centered play therapy (CCPT), a holistic treatment that fosters children's emotional, developmental, and social growth would serve as a viable treatment. The purpose of this study was to examine the effect of CCPT on problem behaviors among children identified with an intellectual disability. Specifically, a single case, A-B-A design (N = 2) was used to examine changes in participant's problem behaviors as measured on the Aberrant Behavior Checklist (ABC) across conditions. Trained raters used the ABC to rate participant's problem behaviors 3 times per week during the course of this study. Participants completed 2 weeks of a no-intervention phase, 5 weeks of play therapy 3 times per week, and 2 weeks of a no-intervention maintenance phase. Additionally, participants were administered the Gesell Developmental Observation to assess their maturational age during the baseline and maintenance phases. Parents also completed the ABC during two intervals: baseline phase, and maintenance phase. Analysis of results indicated that problem behaviors decreased for both participants. Results from the percent of non-overlapping data (PND), an indice for effect size further revealed that play therapy was a very effective treatment for participants. Follow-up interviews suggested that play therapy is a viable intervention for children with intellectual disabilities and problem behaviors. Clinical observations and implications for future research are presented.
Many substance users deny their substance use to avoid negative consequences, thus diluting the accuracy of assessment. To address this issue, indirect items are often included on substance use measures to identify those who deny their use. The purpose of this study was to examine the effect of complete denial and partial denial on substance use measures. Partial denial, also termed denial of effects, is the denial of substance use interfering in multiple domains of a person's functioning. The study used a mixed within- and between-subjects design with participants from a dual diagnosis inpatient unit. Each participant completed the study under two different conditions which include an honest condition and an experimental condition (either complete denial or partial denial). Results show that partial denial is distinctly different from complete denial across three self-report substance use measures. Importantly, substance users engaging in these denial conditions were often undetected by these measures.
Few studies have proposed or evaluated methods to teach telling time. The purpose of this study was to evaluate the effects of differential reinforcement of student responding in the form of response cards to teach three middle school students with intellectual disability to tell time. Participants worked through six training phases. Results showed that correct responding increased from pre-assessment (range of 5.71-14.29% correct) to post-assessment (range of 85-100% correct). Preliminary evidence shows promise in the application of these procedures to teach telling time to middle school students with intellectual disability.
In this study, pro-environmental behaviors are investigated by studying if one's primary information sources about environmental issues either from their social network or the media influence this behavior. Data was collected from the 2002 Detroit Area Study with a total of 267 respondents. Three indexes were constructed to separately measure all seven pro-environment behavioral items, five conservation behavioral items, and two consumption behavioral items. A complex sample model was utilized in these analyses. Findings suggest that information sources are correlated to self-reported environmental behavior. As predicted, the people whose primary information source was social network were more likely to obtain higher scores on all three separate indexes than those individuals who primarily received information about environmental issues from the media.
The purpose of this study was to examine the leadership and school outcome effects of the Texas Principal Improvement program; which authorized the School Leadership Pilot Program under Texas Education Code 11.203. The specific research questions were: What effects did participating in the Texas Principal Excellence Program in 2009-2010 have on participants and their schools? What changes in participants' self-reported and peer-observed leader behaviors occurred between the initial assessment at the onset of the program and the final assessment once the program was completed? What changes were experienced in school's passing rate on mathematics and reading TAKS in schools having the same principal for the two years in 2008-2009 (pre-participation) and 2009-2010 (post participation). The research used TxPEP participating principals who agreed to take part in the study. Principals and a selected group of people who worked with them completed a 360-degree leadership feedback instrument addressing nine leadership competencies at the beginning and end of the program. Paired samples t-tests were used to determine if changes from pre-participation to post-participation were statistically significant. When a statistically significant difference was found, effect size and confidence intervals were calculated to place the data in context. Multiple regression and propensity score matching were used to analyze TAKS data for the second question. The study found that principals believed they were better able to lead after the conclusion of the TxPEP program and that their self-ratings were statistically higher on each of the nine Texas Principal competencies. The results of the 360-degree assessment showed that the peer group felt as if the principals had a statistically significant improvement on three of the nine principal competencies. Regression analysis showed there were no statistically significant changes in the school wide percent passing rates on math or reading TAKS after completion of the TxPEP program. Longitudinal research …
A study was conducted to investigate the relationships between cybergaming treatment groups and the control group (N = 99: ncontrol = 8; nlogic = 29; nspatial = 30; ncombination = 32) with success in the organic chemistry I course as measured by achievement over a 10-week period. The treatment groups included logic training, spatial training, and combination logic-spatial training. Students' ability was measured by pre/post exams using the Group Assessment of Logical Thinking (GALT) to measure logic ability, Purdue Visualizations of Rotations (ROT) test to measure spatial skills, and the General-Organic-Biochemistry (GOB) Exam to measure content attainment. Finally, students' responses about participation in this experience were evaluated using open- and closed-ended questions on a self-developed survey. A second study was conducted to evaluate the relationship between the cybergaming treatment and control groups (N = 88: nexperimental = 27; ncontrol = 61) with success in the general chemistry I course as measured by achievement and final course averages and grades. The cybergaming treatment group underwent intensive combination logic-spatial training for 10 weeks. Students' progress was measured using three pre/post instruments: Group Assessment of Logical Thinking (GALT) measured logic ability, Purdue Visualizations of Rotations (ROT) Test measured spatial skills, and the California Chemistry Diagnostic Exam measured content attainment. Finally, students' responses about their participation in this experience were evaluated using open- and closed-ended questions on a self-developed survey. Analyses of the data were performed to determine the relationships between cybergaming treatments and control groups in organic chemistry I and general chemistry I courses. In organic chemistry I results showed no statistical or practical significance as to students' success. In general chemistry I results indicated statistical significance and medium practicality for students with an average grade of C and for females over males as to improvement of spatial skills.
Manuel Machado is known as one of the most innovative Spanish modernist poets of the twentieth century. Despite his recognition as a literary figure in Spain, the mimetic descriptions in Machado's poetics are interpreted as mere innovations in Spanish poetry. Those mimetic descriptions are examples of ekphrasis in Spanish literature. Ekphrasis is both a literary and representational art. The mimetic dimension in Machado's poetry is ignored or misinterpreted by the critics of his poetics. This study written in Spanish investigates the use of ekphrasis in terms of Machado's poetic style. An analysis of Manuel Machado's ekphrastic poems will determine: ekphrastic poetry is a representational art; how visual and acoustic aspects of Machado's poems create enargeia; and the manifestation of ekphrasis in Spanish verse. In using Machado's poems, this project will contribute to future explorations of ekphrasis in Spanish literature.
Elementary math teachers (76) from selected Texas schools that included Grade 5 responded to an online self-report survey with respect to school-level factors that may be associated with student math achievement. Questions on the survey focused on school-level factors related to math, campus leadership, integration of technology in the math classroom, teacher expectations, utilization of student data in decision-making and professional development. The schools included in the study were rated as Acceptable or Exemplary schools by the Texas Education Agency for three-consecutive years (2007-2010). Logistic regression techniques were used to analyze the data and 11 questions out of 45 were analyzed to determine the odds ratio. Factors that were correlated with being an Exemplary campus were teacher certification routes, not benchmarking student progress, implementation of response to intervention (RTI), classroom management focus (equally divided between student and teacher centered) within the classroom, and technology integration. The results indicated that at the .05 level of probability, the only factor that met that level of significance was full implementation of RTI.
Pain and performance anxiety (PA) are common problems among string players. Therefore, the purpose of this study was to assess and compare PA and prevalence rates and locations of pain in violinists, violists, cellists, and bassists. Subjects completed a questionnaire that included sections on demographics, musical background, practice habits, musculoskeletal problems, non-musculoskeletal problems, and PA. Anthropometric data were gathered on all 115 subjects. Results show that there are differences in both pain and PA across instrument groups. Violinists reported the highest number of pain sites, followed by violists, bassists, and cellists. The left shoulder was the most-often reported pain site, followed by the neck and right shoulder. Aching was the most cited term selected to describe pain. Several anthropometric indices were significantly correlated with pain, notably right thumb to index finger span in both cellists and bassists. In all instrument groups, at least one pain site was significantly correlated with one of four PA questions. Results warrant the development of intervention strategies and further study of the relationship between pain and performance anxiety.
This study in the aerospace ground equipment (AGE) apprentice course at Sheppard Air Force Base, Texas, examined the use of mobile digital devices to determine which device leveraged the best results and was most compatible with military technical training requirements. The sample consisted of 160 students who attended the course between January and June, 2010. Three devices loaded with course materials were issued to the students, who used the devices in the classroom and were encouraged to use the devices to enhance their study time after class. Quantitative data were obtained by comparing block test scores to determine if any device produced a significant change in student learning. Qualitative data were collected from surveys administered to instructors and students to measure which device instructors and students found easiest to understand and use, and student satisfaction with the device. An analysis of variance (ANOVA) revealed a statistically significant difference (p < .05) in the block test mean scores between groups using mobile devices and the students in the control group that had no device. Post hoc comparisons on each block showed that there was a statistically significant difference between students using the smartphone and students using the other devices, but no statistically significant difference in the block test mean scores between students using the iPod and the netbook. The netbook leveraged the best results, both in block test scores and student satisfaction. The greatest reported disadvantage of the smartphone and the iPod Touch was the small screen size.
Claude Debussy is considered one of the most influential figures of the late 19th century and early 20th centuries. Among the various works that he wrote for the piano, Children's Corner and La Boîte à joujoux distinguish themselves as being evocative of childhood. However, compared to more substantial works like Pelléas et Mélisande or La Mer, his children's piano music has been underrated and seldom performed. Children's Corner and La Boîte à joujoux were influenced by a series of eclectic sources, including jazz, novel "views" from Russian composers, and traditional musical elements such as folk songs and Eastern music. The study examines several stylistic parallels found in these two pieces and is followed by a discussion of Debussy's use of musical quotations and allusions, important elements used by the composer to achieve what could be dubbed as a unique "children's wonderland."
Corporate diversification continues to be an important phenomenon in the modern business world. More than thirty years of research on diversification suggests that the degree of relatedness among a firm's business units is a factor that can affect firm performance, but the true effect of diversification relatedness on firm performance is still inconclusive. The purpose of this dissertation is to shed more light on this inconclusive association. However, attention is focused on the performance implications of individual diversification actions (e.g., acquisitions and joint ventures) rather than on the overall performance of firms with different levels of diversification. A non-experimental, longitudinal analysis of secondary data was conducted on over 450 unique acquisitions and on more than 210 joint ventures. Results suggest that even when individual diversification actions rather than entire business portfolios are examined, an inverted curvilinear association between diversification relatedness and performance is likely to emerge. This pattern is observed in both acquisitions and joint ventures. However, the association between diversification relatedness and performance in acquisitions is moderated by the level of industry adversity, though factors such as corporate coherence and heterogeneous experience do not moderate the association between diversification relatedness and performance. This study augments the body of knowledge on diversification and adds refinement to the traditional curvilinear finding regarding relatedness. By studying acquisitions and joint ventures independently, the results reveal differences in both slope and inflection points that suggest the relative impact of relatedness may vary depending on the mode of diversification.
Previous research has shown that alcohol abuse may cause a deficit in frontal lobe functioning, specifically, areas of the frontal lobe that are related to executive function. Additionally, problems with executive function have been related to increased difficulty in managing cravings to addictive substances. The current study explored the relationship between alcohol use and performance on measures of executive functioning in a sample of 121 traditional college students. Students were given 5 measures of executive function designed to explore mental set shifting, updating, inhibition, sustained attention, and planning. These measures were used to examine the relationship between executive function and craving as measured by the Obsessive Compulsive Drinking Scale. Levels of alcohol use were also examined using the Alcohol Use Disorders Identification Test in relation to executive function performance and family history of alcohol abuse.
Retail geography is an expanding field that is becoming increasingly important within academia, the business environment, and the national and global economy. The focus of this study is to provide insight and additional understanding of the site selection processes employed by Wal-Mart in the United States. The research studies Wal-Mart from a national perspective and investigates the patterns of retail store expansion across the United States from 1990 to 2005. The study employs the use of a continuous Poisson model to check for significant clustering, and a single and multiple correlation analysis to identify the types of relationships that exist between retail stores and location. The results of the study make apparent several distinct patterns of retail store dispersion within the United States between the years 1990 to 2005.
Fluidization of biomass particles is an important process in the gasification, pyrolysis and combustion in order to extract energy from biomass. Studies on the fluidization of biomass particles (corn cob and walnut shell), inert particles (sand, glass bead, and alumina), which are added to facilitate fluidization of biomass, and biomass/sand mixture were performed. Experiments were carried out in a 14.5 cm internal diameter cold flow fluidization bed to determine minimum fluidization velocities with air as fluidizing medium. On the of basis of experimental data from both present work and those found in the literature, new correlations were developed to predict minimum fluidization velocity for inert particles as well as biomass particles. It was found that the proposed correlations satisfactorily predict minimum fluidization velocities and was in well agreement with experimental data. Furthermore, effect of weight percentage of biomass in the biomass/sand mixtures was studied. The weight fraction of biomass particles in the mixture was chosen in the range of 0 ~ 100 wt. %. The results show that minimum fluidization velocity of the mixtures increases with an increase in biomass content. Using the present experimental data, a new correlation was developed in terms of mass ratio for predicting values of minimum fluidization velocity of these mixtures. However, the validity of the proposed correlation should be further studied by conducting more experiments using the biomass/sand mixtures of different particle size, shape, and density.
This qualitative study explored Facebook as a communication tool for student affairs and compared it as a source with other communication modalities to describe the 18-24 year old student preference on receiving information about student affairs departments and activities. The research questions were designed to provide feedback on the current purpose[s] of student use of Facebook for student affairs services as well as reporting additional services and activities that would be considered through the use of Facebook. Differences in use among institutional types were also explored. The results of 395 online survey responses were compared to focus groups consisting of student ambassadors at a two-year public, four-year private, and four-year public institution. The online survey participants were asked to respond to specific modes of communication based upon each service or activity. The focus groups were asked the same questions in an open-ended format and the results were compared to the online results. The results indicate that depending on the event or activity, the students preferred a different method of communication, not necessarily Facebook for information on student affairs programming. These results also differed among institutional types. Two-year institutions have the greatest potential to increase their presence on Facebook. One theme that emerged from the open-ended response question in the online survey was that institutions participating on Facebook should limit content so that it is more social in nature and leave academically related issues to institutionally driven communication modalities. There are numerous options to communicate information to students and finding the best one may be more challenging than actually disseminating the information. With the administrative challenges and lack of student responses encouraging Facebook usage, institutions of higher education are not encouraged to spend enormous resources in this one particular communication modality. Given the high number of responses from the online survey …
