Medication adherence among the elderly: A test of the effects of the Liberty 6000 technology. (open access)

Medication adherence among the elderly: A test of the effects of the Liberty 6000 technology.

Medication adherence is a formidable challenge for the elderly who may have several prescribed medications while dealing with limited incomes and declining health. The primary purpose of this study was to evaluate the Liberty 6000, an automated capsule and tablet dispenser that provides proper medication dosages and is intended to encourage and track medication adherence. Seven focus groups were assembled; these comprised 49 men and women ages 65 to 98 years of Black, Anglo, and Hispanic descent who met the following criteria: living independently or semi-independently, had suffered one or more impairments, and were taking at least three prescription medications. Each focus group session lasted 90 minutes and was tape-recorded and transcribed verbatim, resulting in about 2,600 lines of text. Each question was designed to be open-ended to avoid introducing any bias that might influence the response. The Health Belief Model conceptually guided the study that addressed perceptions of illness susceptibility and severity, barriers, benefits, and cues to action associated with medication adherence. Main benefits of taking medications included avoiding inherited illnesses (or tendencies for illnesses), and reducing illness symptoms. Barriers to taking medications included forgetting, dexterity problems, and high cost. Benefits of the proposed intervention included reminding, caregiver notification, …

Aesthetic Models and Structural Features in Concerto for Solo Percussion and Concert Band (open access)

Aesthetic Models and Structural Features in Concerto for Solo Percussion and Concert Band

Concerto for Solo Percussion and Concert Band was commissioned by Staff Sergeant Rone Sparrow, a percussionist with the West Point Military Academy Band. Funding for the project was provided by the Barlow Foundation. The piece was premiered April 13, 2005 in the Eisenhower Hall Theater at West Point, New York. Rone Sparrow performed with the USMA band, and Colonel Thomas Rotondi Jr., Commander/Conductor, conducted the piece. The concerto consists of three movements, and each movement features a different instrument: the first features marimba, the second, vibraphone, and the third movement features the drum kit together with a rhythm section (piano, bass, and drums). In addition to the piece, the dissertation paper discusses important technical detail related to the piece, including: harmony, form, rhythm, programmatic ideas as they relate to motivic strands, and the process of generating and discarding material. The paper also focuses on a number of factors that were influential to the piece, such as postmodern philosophy.

Shaping Cows' Approach to Humans Using Positive and Negative Reinforcement (open access)

Shaping Cows' Approach to Humans Using Positive and Negative Reinforcement

Negative reinforcement can be a powerful tool for behavior analysts, yet it is often overlooked as a treatment method. Pryor (1999) outlines a method for approaching a "timid" animal using a combination of negative reinforcement and positive reinforcement. When the animal stands still, the human operates a clicker, and then retreats from the animal. Gradually, the human moves closer to the animal through the clicking and retreating shaping process. Once the human is standing close enough, food may be offered as a positive reinforcer, and the negative reinforcer is canceled out. The purpose of this study was to experimentally demonstrate the click-retreat technique with cows. A multiple-baseline design across subjects was used to test this technique. Results show that the click and retreat technique was effective. Results are discussed in terms of the difference between the click-retreat technique and systematic desensitization.

FP-tree Based Spatial Co-location Pattern Mining (open access)

FP-tree Based Spatial Co-location Pattern Mining

A co-location pattern is a set of spatial features frequently located together in space. A frequent pattern is a set of items that frequently appears in a transaction database. Since its introduction, the paradigm of frequent pattern mining has undergone a shift from candidate generation-and-test based approaches to projection based approaches. Co-location patterns resemble frequent patterns in many aspects. However, the lack of transaction concept, which is crucial in frequent pattern mining, makes the similar shift of paradigm in co-location pattern mining very difficult. This thesis investigates a projection based co-location pattern mining paradigm. In particular, a FP-tree based co-location mining framework and an algorithm called FP-CM, for FP-tree based co-location miner, are proposed. It is proved that FP-CM is complete, correct, and only requires a small constant number of database scans. The experimental results show that FP-CM outperforms candidate generation-and-test based co-location miner by an order of magnitude.

The Effect of SFAS No. 141 and SFAS No. 142 on the Accuracy of Financial Analysts' Earnings Forecasts after Mergers (open access)

The Effect of SFAS No. 141 and SFAS No. 142 on the Accuracy of Financial Analysts' Earnings Forecasts after Mergers

This study examines the impact of Statements of Financial Accounting Standards No. 141 and No. 142 (hereafter SFAS 141, 142) on the characteristics of financial analysts' earnings forecasts after mergers. Specifically, I predict lower forecast errors for firms that experienced mergers after the enactment of SFAS 141, 142 than for firms that went through business combinations before those accounting changes. Study results present strong evidence that earnings forecast errors for companies involved in merging and acquisition activity decreased after the adoption of SFAS 141, 142. Test results also suggest that lower earnings forecast errors are attributable to factors specific to merging companies such as SFAS 141, 142 but not common to merging and non-merging companies. In addition, evidence implies that information in corporate annual reports of merging companies plays the critical role in this decrease of earnings forecast error. Summarily, I report that SFAS 141, 142 were effective in achieving greater transparency of financial reporting after mergers. In my complementary analysis, I also document the structure of corporate analysts' coverage in "leaders/followers" terms and conduct tests for differences in this structure: (1) across post-SFAS 141,142/pre-SFAS 141, 142 environments, and (2) between merging and non-merging firms. Although I do not identify …

Perceived features and similarity of images: An investigation into their relationships and a test of Tversky's contrast model. (open access)

Perceived features and similarity of images: An investigation into their relationships and a test of Tversky's contrast model.

The creation, storage, manipulation, and transmission of images have become less costly and more efficient. Consequently, the numbers of images and their users are growing rapidly. This poses challenges to those who organize and provide access to them. One of these challenges is similarity matching. Most current content-based image retrieval (CBIR) systems which can extract only low-level visual features such as color, shape, and texture, use similarity measures based on geometric models of similarity. However, most human similarity judgment data violate the metric axioms of these models. Tversky's (1977) contrast model, which defines similarity as a feature contrast task and equates the degree of similarity of two stimuli to a linear combination of their common and distinctive features, explains human similarity judgments much better than the geometric models. This study tested the contrast model as a conceptual framework to investigate the nature of the relationships between features and similarity of images as perceived by human judges. Data were collected from 150 participants who performed two tasks: an image description and a similarity judgment task. Qualitative methods (content analysis) and quantitative (correlational) methods were used to seek answers to four research questions related to the relationships between common and distinctive features …

The school reform movement and high stakes standardized testing: An analysis of factors impacting the academic outcomes of students receiving special education services.

The purpose of this study was to investigate special education outcomes in relation to state standardized testing. It specifically sought to determine if a relationship existed between selected data from the Texas Academic Excellence Indicator System (AEIS) comparing district students receiving special education services TAAS scores with selected district demographic, fiscal, and special education data. The population for this study consisted of all 2001-2002 grades 3-8 and 10 public school students with the exception of charter schools, special-purpose statutory districts, and state-administered districts. The reading analysis incorporated data from 896 Texas school districts. The mathematics analysis used data from 914 school districts. Multiple linear hierarchical regression was chosen as the method for statistical analysis. Data was obtained from the Texas Education Agency (TEA) as a special data pull. For both the reading and mathematics analyses, wealth and ethnicity were statistically insignificant although ethnicity individually accounted for a large percentage of the variance for both the reading (20.3%) and mathematics (13.2%) scores as well as producing negative β weights. All other predictor variables produced varying degrees of statistical significance. Community type, socioeconomic status, instructional expenditures per students, and instructional expenditures per student receiving special education services also produced negative β weights. …

The Effects of Bilingual Education on Reading Test Scores: Can Dual-immersion Support Literacy for All Students? (open access)

The Effects of Bilingual Education on Reading Test Scores: Can Dual-immersion Support Literacy for All Students?

Dual-immersion is a bilingual education method offered that places English as a first language (EFL) and English language learner (ELL) students in the same classroom to learn two languages at the same time. This study examines whether second language acquisition through dual-immersion supports literacy for both ELL and EFLS children over time. Students' scores on standardized tests (ITBS, TAKS, Logramos, Stanford 9, and Aprenda) were studied to assess the impact, if any, of dual-immersion instruction vs. regular/bilingual education on reading development. Scores from 2000 through 2004 were gathered and analyzed for students enrolled in a dual-immersion class which started in kindergarten in 2000. These scores were compared to scores of students enrolled in regular and bilingual education classrooms for the same amount of time at the same school to examine whether there was an effect for students in the dual-immersion class. It was found that no significant difference existed between the groups. All groups were performing at a passing level on the standardized tests. The dual-immersion class was performing as well as the regular education class on standardized tests in both English and Spanish.

Exploring Lifestyle Orientation, Attitudes Toward Lifestyle Merchandising, and Attitudes Toward Lifestyle Advertising as Predictors of Behavioral Intention to Purchase Lifestyle Home Furnishing Products (open access)

Exploring Lifestyle Orientation, Attitudes Toward Lifestyle Merchandising, and Attitudes Toward Lifestyle Advertising as Predictors of Behavioral Intention to Purchase Lifestyle Home Furnishing Products

A number of lifestyle merchandising and advertising strategies are being used in the home furnishings industry. However, there is limited research regarding the effectiveness of these strategies. The purpose of this study was to explore consumers' attitudes toward the lifestyle concept. Analyses of several consumer behavior variables and descriptors offered noteworthy findings for the home furnishings industry. This study found that although lifestyle orientation is a valuable tool for delineating consumer markets, these segmentations were not significant determinates of consumers' preference for elements of the lifestyle construct. Retailers and manufacturers are not simply creating home furnishing collections that target the needs of specific psychographic segment, but rather creating lifestyles being aspired to obtain. Although respondents scored the attitude variables neutral, the current market environment offers many examples of successfully home furnishing implementations of the lifestyle concept. These success stories coupled with additional findings indicate consumers' positive response to lifestyle merchandising.

Primary revenue streams of Hispanic-serving community colleges in Texas. (open access)

Primary revenue streams of Hispanic-serving community colleges in Texas.

This study examined the extent and sources of primary revenue for Hispanic-, African-American-, and Caucasian-serving public community colleges in Texas. The study also examined differences between and among primary revenue streams for these institutions. The public community colleges were identified as Hispanic-, African-American-, and Caucasian-serving based upon the percentage of enrollments for each ethnic classification. A comparative model was developed for the primary revenue streams of in-district student tuition, out-of-district student tuition differentials, out-of-state student tuition differentials, ad valorem property tax revenue per in-district contact hour, and state appropriations. Statistical Packages for the Social Sciences (SPSS) was utilized to conduct multiple-factor analysis of variance (ANOVA) on the data set to examine differences between and among the several variables. Post hoc tests were performed where necessary. Difference was identified in in-district student tuition. Post hoc analysis demonstrated that difference existed between Hispanic-serving and African-American-serving community colleges. No difference was identified in the remaining primary revenue streams.

Saturation and foaming of thermoplastic nanocomposites using supercritical CO2. (open access)

Saturation and foaming of thermoplastic nanocomposites using supercritical CO2.

Polystyrene (PS) nanocomposite foams were prepared using supercritical fluid (SCF) CO2 as a solvent and blowing agent. PS was first in-situ polymerized with a range of concentrations of montmorillonite layered silicate (MLS). The polymerized samples were then compression molded into 1 to 2mm thick laminates. The laminates were foamed in a batch supercritical CO2 process at various temperatures and pressures from 60°-85°C and 7.6-12MPa. The resulting foams were analyzed by scanning electron microscopy to determine effect of MLS on cellular morphology. Differential scanning calorimetry was used to determine the impact of nanocomposite microstructure on glass transition of the foamed polymer. X-ray diffraction spectra suggested that the PS/MLS composite had an intercalated structure at both the 1% and 3% mixtures, and that the intercalation may be enhanced by the foaming process.

A magnetorheological study of single-walled and multi-walled carbon nanotube dispersions in mineral oil and epoxy resin. (open access)

A magnetorheological study of single-walled and multi-walled carbon nanotube dispersions in mineral oil and epoxy resin.

Single wall carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs) were dispersed in mineral oil and epoxy resin. The magnetorheological properties of these dispersions were studied using a parallel plate rheometer. Strain sweeps, frequency sweeps, magneto sweeps and steady shear tests were conducted in various magnetic fields. G', G", h* and ty increased with increasing magnetic field, which was partially attributed to the increasing degree of the alignment of nanotubes in a stronger magnetic field. The SWNT/mo dispersions exhibited more pronounced magnetic field dependence than SWNT/ep and MWNT/mo counterparts due to their much lower viscosity. The alignment of SWNTs in mineral oil increased with rising nanotube concentration up to 2.5vol% but were significantly restricted at 6.41vol% due to nanotube flocculation.

Treatment Outcomes Related to EEG-Biofeedback for Chemical Dependency: Changes in MMPI-2™ (University of Minnesota) Personality Measures and Long Term Abstinence Rates

Peniston and Kulkosky (1989, 1990) demonstrated the effectiveness of alpha-theta EEG-Biofeedback (EEG-BFB) in treating inpatient alcoholics noting significant improvements in depression, psychopathology, serum β-endorphin levels, and abstinence rates. The present study is an extension of a previously unpublished replication of the Peniston EEG-BFB protocol with 20 chemically dependent outpatients (Bodenhamer-Davis, Callaway, & DeBeus, 2002). Fifteen subjects were "high risk for re-arrest" probationers. Data for the EEG-BFB group was collected from archival records. Subjects completed an average of 39 sessions (SD = 6.096), with 33 of those being EEG-BFB. Pre/post-treatment MMPI-2s™ (University of Minnesota) were collected and follow-up (4-11 years) data obtained (abstinence rates, re-arrests in some cases). Treatment effects were evaluated by comparing assessment data (pre/post) and documenting abstinence rates. Post-treatment MMPI-2 results were within normal limits, with several scales significantly reduced from baseline suggesting less psychopathology. Results were then compared to 20 subjects receiving standard addiction treatment (OT-CD group), but not EEG-BFB. OT-CD subjects completed a 2-week inpatient program followed by 18 outpatient sessions. Pre/post assessment and follow-up data was collected on the OT-CD group. The OT-CD group's post-assessment results showed three elevations (MMPI-2 scales 4/6/8), suggestive of characteriological problems. Post-MMPI-2 results of the two groups were compared via …

Charge Interaction Effects in Epoxy with Cation Exchanged Montmorillonite Clay and Carbon Nanotubes. (open access)

Charge Interaction Effects in Epoxy with Cation Exchanged Montmorillonite Clay and Carbon Nanotubes.

The influence of charge heterogeneity in nanoparticles such as montmorillonite layered silicates (MLS) and hybrid systems of MLS + carbon nanotubes was investigated in cured and uncured epoxy. Epoxy nanocomposites made with cation-exchanged montmorillonite clay were found to form agglomerates near a critical concentration. Using differential scanning calorimetry it was determined that the mixing temperature of the epoxy + MLS mixture prior to the addition of the curing agent critically influenced the formation of the agglomerate. Cured epoxy samples showed evidence of the agglomerate being residual charge driven by maxima and minima in the concentration profiles of thermal conductivity and dielectric permittivity respectively. A hybrid nanocomposite of MLS and aniline functionalized multi walled nanotubes indicated no agglomerates. The influence of environmentally and process driven properties on the nanocomposites was investigated by examination of moisture, ultrasound, microwaves and mechanical fatigue on the properties of the hybrid systems. The results point to the importance of charge screening by adsorbed or reacted water and on nanoparticulates.

The Waning of Victorian Imperialism: Stylistic Dualism in Gustav Holst's One-Act Opera Sāvitri (1908-9) (open access)

The Waning of Victorian Imperialism: Stylistic Dualism in Gustav Holst's One-Act Opera Sāvitri (1908-9)

Gustav Holst's one-act opera Sāvitri (1908-9) represents a turning point in his compositional style, which came at a significant time in British history. Holst combines a simpler style informed by his work with English folksong with the Wagnerian style that permeated his earlier compositions. Although influenced by a British imperialist view of the world, Sāvitri renders Hindu-Indian culture in positive terms without relying on the purely exotic, offers a perspective on gender relationships that does not depend solely on convention, and presents the commoner as the British ideal rather than romanticizing the aristocracy. The result is an opera subtle in its complexity, approaching the profound themes of love, death, and spirituality with emotional restraint and self-control.

Philosophical Implications on Trombone Performance and Pedagogy in Andre Lafosse's Curriculum at the Paris Conservatory (open access)

Philosophical Implications on Trombone Performance and Pedagogy in Andre Lafosse's Curriculum at the Paris Conservatory

During his tenure as the professor of trombone at the Paris Conservatory, Andre Lafosse wrote the Traite de Pedagogie du Trombone a Coulisse addressing trombone pedagogy that was to be studied in conjunction with his method and etude books, Methode Complete de Trombone and Vade Mecum du Tromboniste. The pedagogic philosophy reflects Lafosse's own experiences as an orchestral musician in France in the early 20th century. Lafosse designed and used his treatise to prepare students to be effective teachers after their graduation from the Conservatory. The scope of preparation for Lafosse's trombone class, however, was limited. He did not attempt to provide a text or tutor that would prepare trombonists for any career in music: Lafosse was primarily concerned with orchestral trombone playing, as reflected in musical exercises, instrument designation, and repertoire references. Solo performance skills are also explained at length in his treatise, and Lafosse includes his own solo transcriptions in the curriculum. This emphasis placed on performing as a soloist appears to oppose Lafosse's implied preference for orchestral performance. Throughout his career as a trombone professor Andre Lafosse compiled and wrote music that emphasized elements of trombone technique based on the French solo and orchestral repertoire. His primary …

Risk Factors for Vascular Dementia (open access)

Risk Factors for Vascular Dementia

Dementia is a devastating disorder that commonly affects people over the age of 65. Alzheimer's disease and vascular dementia are the most common forms of dementias. A number of studies have implicated cardiovascular risks as important factors in the development of dementia. These risks include high-risk behaviors such as smoking and risks related at least partially to health behaviors such as diet and exercise. This study examines a group of cardiovascular risk factors, as defined by the Framingham study, to ascertain if they are predictors of dementia. A retrospective chart review of 481consecutive patients seen in a geriatric medicine clinic produced a sample of 177 individuals diagnosed with dementia and 304 individuals without a dementia diagnosis. Relative risk ratio (RRR) results indicate that a history of hypertension (RRR= 1.80, p = .009) and a history of hypercholesterolemia (RRR = 1.85, p = .016) are significant predictors of Alzheimer's disease. A history of tobacco use (RRR = 2.18, p = .01) is a significant predictor of vascular dementia. Stepwise regression analyses indicate that hypercholesterolemia is an independent predictor of dementia (b = -.113, p = .009) and hypercholesterolemia (b = -.104, p = .018) and hypertension (b = -.094, p = …

This thesis explores the possibilities of communication in the context of a sound composition. In RevealingReveilingReveling, a series of questions concerning communication posed by John Cage, coupled with an extension of those questions posed by myself, are set to recorded sounds-in-the-world. The intention is to create a greater awareness of that which there is to listen in our world. The first part of this essay discusses influences of philosophical thought during the process of composing RevealingReveilingReveling. Two distinct twentieth-century thinkers that have impacted the creation of this piece and their areas of thought are Martin Heidegger: language and Being; and John Cage: sound, silence, and awareness. The second part of the essay is a structural analysis of the piece, discussing the recording of Cage's questions, sounds-in-the-world, sound-manipulation techniques and thought-processes, as well as periodic mention the aesthetic decisions made.

Poetry and Patronage: Alessandro Scarlatti, The Accademia Degli Arcadia, and the Development of the Conversazione Cantata in Rome 1700-1710

The special relationship of patrons, librettists, and composers, in the Accademia degli'Arcadia in Rome from 1700-1710 appears in Alessandro Scarlatti's settings of Antonio Ottoboni's cantata librettos in the anthology GB Lbm. Add. 34056. An examination of Arcadian cantatas and their texts reveals the nature of their audience, function, and their place within the historical development of the genre. The conversazione cantata did not exist outside of Rome and was popular for only a brief period in the early eighteenth century. Critical examination of primary sources, including minutes from the Arcadian Academy meetings as well as household documents regarding the Cardinals Ottoboni and Pamphili, Prince Ruspoli, and other noble families, sheds light on the culture of the Arcadian Academy and the cantata within it, broader study clarifies the individuality of the conversazione cantata within Rome, and closer study of the contribution of the greatest cantata composer 1700-1710, Alessandro Scarlatti.

Institutions and Drug Markets

This thesis examines how drug policy and enforcement affect drug manufacturers. The approach taken is a comparative institutional analysis of cannabis and methamphetamine production. I focus on the effects of prohibition, privacy, and clandestine markets on producer behavior for these two drugs and the unintended consequences that result. I demonstrate that cannabis and methamphetamine producers both face substantial transaction costs and that producers alter their behavior to manage these transaction costs. I conclude that cannabis producers can adopt indoor, small-scale operations to hide their activity, which are capable of yielding continuous, high-potency crops. Methamphetamine producers also adopt small-scale, decentralized strategies, but commodity control increases their exposure and leads to greater overall transaction costs during the manufacturing process.

Character Education Programs and Student Suspension Rates from School: Do Character Education Programs Decrease Student Suspensions from Regular Instructional Public Elementary Schools in Texas?

The purpose of this study was to determine if character education programs impact the suspension rates of students from regular instructional public elementary schools in Texas. The data was also examined to determine if the number of years since a school's implementation of a character education program has an impact on the effectiveness of the programs as measured by the suspension rates of students from school. Finally, the study sought to determine if the socio-economic status of the schools has an impact on the effectiveness of character education programs as measured by the student suspension rates. A random sample of 135 regular instructional public elementary schools in Texas was collected. The principal of each school completed a questionnaire that was used to sort schools into three groups: schools with "direct" character education programs, schools with "indirect" character education programs, and schools that have implemented no type of character education program. A two-year history of suspensions was obtained for each school. The data was analyzed using one-way and two-way ANOVAs. The results of the analyses indicated that the implementation of character education programs, no matter what type, did not produce statistically significant differences in student suspension rates from school.

Dynamics, Thermodynamic formalism and Perturbations of Transcendental Entire Functions of Finite Singular Type

In this dissertation, we study the dynamics, fractal geometry and the topology of the Julia set of functions in the family H which is a set in the class S, the Speiser class of entire transcendental functions which have only finitely many singular values. One can think of a function from H as a generalized expanding function from the cosh family. We shall build a version of thermodynamic formalism for functions in H and we shall show among others, the existence and uniqueness of a conformal measure. Then we prove a Bowen's type formula, i.e. we show that the Hausdorff dimension of the set of returning points, is the unique zero of the pressure function. We shall also study conjugacies in the family H, perturbation of functions in the family and related dynamical properties. We define Perron-Frobenius operators for some functions naturally associated with functions in the family H and then, using fundamental properties of these operators, we shall prove the important result that the Hausdorff dimension of the subset of returning points depends analytically on the parameter taken from a small open subset of the n-dimensional parameter space.

Amon Carter: The Founder of Modern Fort Worth, 1930-1955

From 1930 to 1955, Amon Carter, publisher of the Fort Worth Star-Telegram, exerted his power to create modern Fort Worth. Carter used his stature as the publisher of the city's major newspaper to build a modern city out of this livestock center. Between 1930 and 1955, Carter lobbied successfully for New Deal funds for Fort Worth, persuaded Consolidated Aircraft to build an airplane plant in the city, and convinced Burlington Railways to stay in the city. He also labored unsuccessfully to have the Trinity River Canal built and to secure a General Motors plant for Fort Worth. These efforts demonstrate that Carter was indeed the founder of modern Fort Worth.
