Despite the central importance of conditional discriminations to the derivation of equivalence relations, there is little research relating the dynamics of conditional discrimination learning to the derivation of equivalence relations. Prior research has shown that conditional discriminations with simple sample and comparison stimuli are acquired faster than conditional discriminations with complex sample and comparison stimuli. This study attempted to replicate these earlier results and extend them by attempting to relate conditional discrimination learning to equivalence relations. Each of four adult humans learned four, four-choice conditional discriminations (simple-simple, simple-complex, complex-simple, and complex-complex) and were tested to see if equivalence relations had developed. The results confirm earlier findings showing acquisition to be facilitated with simple stimuli and retarded with complex stimuli. There was no difference in outcomes on equivalence tests, however. The results are in implicit agreement with Sidman's theory of stimulus equivalence.

Wetting of a substance has been widely investigated since it has many applications to many different fields. Wetting principles can be applied to better select cleans for front end of line (FEOL) and back end of line (BEOL) cleaning processes. These principles can also be used to help determine processes that best repel water from a semiconductor device. It is known that the value of the dielectric constant in an insulator increases when water is absorbed. These contact angle experiments will determine which processes can eliminate water absorption. Wetting is measured by the contact angle between a solid and a liquid. It is known that roughness plays a crucial role on the wetting of a substance. Different surface groups also affect the wetting of a surface. In this work, it was investigated how wetting was affected by different solid surfaces with different chemistries and different roughness. Four different materials were used: silicon; thermally grown silicon dioxide on silicon; chemically vapor deposited (CVD) silicon dioxide on silicon made from tetraethyl orthosilicate (TEOS); and organosilicate glass (OSG) on silicon. The contact angle of each of the samples was measured using a goniometer. The roughness of the samples was measured by atomic force …

Most newspapers today are struggling to survive in an increasingly fragmented and digital media environment. How have their owners or corporate parents shaped or adapted their business practices to in order to thrive? This question guides the overall approach to this study. The focus is on one newspaper, the Dallas Morning News. In particular, how has the News used corporate messages to respond to the changing media landscape? This study employs forms of rhetorical and discourse analysis to determine the effectiveness of the News' corporate messages during a 10-year period in order to answer this question. This study finds that the News used inconsistent and ineffective corporate communications throughout this tumultuous period.

In Vienna from about 1918 until the 1930s, contemporaries perceived a high point in the music-historical significance of Mahler's works, with regard to both the history of compositional style and the social history of music. The ideas and meanings that became attached to Mahler's works in this milieu are tied inextricably to the city's political and cultural life. Although the performances of Mahler's works under the auspices of Vienna's Social Democrats are sometimes construed today as mere acts of political appropriation, David Josef Bach's writings suggest that the innovative and controversial aspects of Mahler's works held social value in line with the ideal of Arbeiterbildung. Richard Specht, Arnold Schoenberg, and Theodor Adorno embraced oft-criticized features in Mahler's music, regarding the composer as a prophetic artist whose compositional style was the epitome of faithful adherence to one's inner artistic vision, regardless of its popularity. While all three critics addressed the relationship between detail and whole in Mahler's music, Adorno construed it as an act of subversion. Mahler's popularity also affected Viennese composers during this time in obvious and subtle ways. The formal structure and thematic construction of Berg's Chamber Concerto suggest a compositional approach close to what his student Adorno described …

Play is a significant part of childhood. Typically developing children exhibit a wide range of interests within their play behavior, but children with autism do not. The purpose of this study was to design and implement an assessment tool that will capture the constellation of behaviors indicating play interests in young children. The Early Play Interests Assessment (EPIA) includes categories of play behavior and their components behaviors. Additionally, measures of child affect were built into the EPIA. All behaviors were observed under various environmental conditions. The results show that the EPIA was useful in observing toddlers' play behavior within behavioral categories and components and in assessing the interactions among these measures of play interests. The results are discussed in relation to the importance of creating observational systems to quantify play interests in typical and atypical children and for establishing a link between the information gathered in assessment and the planning and implementation of autism interventions.

The sociocultural model of eating pathology is an empirically-supported model explaining eating disorder etiology. The model poses that body dissatisfaction and subsequent eating pathology stems from the unrealistic standards formulated by Westernized society. Although the model has strong empirical support, variables within the model do not account for 100% of the variance in disordered eating. Thus, the current researcher attempted to explore potential moderating factors in the sociocultural model of eating disorders that may help to explain variance currently unaccounted for. In particular, the researcher focused on the relationship between sociocultural internalization and body dissatisfaction, given that this relationship has not been previously explored within the literature. Based on theoretical support, the researcher chose several potential variables to test, including perfectionism, neuroticism, body surveillance, and shame. Primary analyses tested each variable for moderating effects using hierarchical moderated regression, but no significant findings were shown. Results of post hoc analyses showed all variables had significant mediating effects, with the exception of self-oriented perfectionism. The discussion section addresses consistency with previous research, limitations of the present study, treatment implications and guidelines for future research.

Smart structures are relevant and significant because of their relevance to phenomena such as hazard mitigation, structural health monitoring and energy saving. Electrical resistance could potentially serve as an indicator of structural well-being or damage in the structure. To this end, the development of a microprocessor-based automated resistance measurement system with customized GUI is desired. In this research, a nodal electrical resistance acquisition circuit (NERAC) system was designed. The system hardware interfaces to a laptop, which houses a customized GUI developed using DAQFactory software. Resistance/impedance was measured using DC/AC methods with four-point probes technique, on three substrates. Baseline reading before damage was noted and compared with the resistance measured after damage. The device was calibrated and validated on three different substrates. Resistance measurements were taken from PVDF samples, composite panels and smart concrete. Results conformed to previous work done on these substrates, validating the effective working of the NERAC device.

This study extends research findings directed at a micro-focus of change by assessing individual organizational members' perspectives and psychological constructs influencing change efforts by an organization. The change initiative in question regards the construction of a new facility and subsequent relocation to said facility. Moral commitment to the organization (negative), change initiative's fit with organizational vision, and social influence significantly contributed to variance in members' affective commitment to change. Trust in leadership and normative commitment to the organization (NCO) significantly contributed to variance in members' normative commitment to change. Continuance commitment to the organization and participation (negative) significantly contributed to variance in members' continuance commitment to change. NCO, change initiative's fit with organizational vision, and participation significantly contributed to variance in support of the proposed change initiative. Affective commitment to the organization (negative), NCO (negative), trust in leadership (negative), and disruption of influence significantly contributed to variance in members' intent to leave the organization.

The purpose of this study was to explore the following relationships: (a) how moderating factors (gender, age, ethnicity, social support, marital status, reason for role assumption and number of grandchildren in the home) can influence the mediating role of resiliency, and (b) how resiliency may mediate the negative effects of raising grandchildren (role demands, life disruptions, and difficulties with grandchildren) on grandparent adjustment over time. Resiliency was hypothesized to have the greatest effect on custodial grandparents who experienced the most stress (i.e., older, single, Caucasian males lacking social support and raising more than one grandchild). Mediation was assessed using structural equation modeling. Results indicated resilience mediated the relationship between role assumptions (i.e., role demands and life disruptions) and grandparent adjustment; however, resilience did not mediate the relationship between grandchild characteristics and grandparent adjustment. Due to the small number of custodial grandfathers (n = 14), non-married grandparents (n = 29), non-Caucasian grandparents (n = 10), the small number of grandparents who assumed the custodial role for less ambiguous reasons (n = 24), and the number of custodial grandparents with more than one grandchild residing in the home (n = 29) participating within the study, hierarchical multiple regressions were only conducted to …

I investigate the spoken dialogue of four Indian novels in English: Mulk Raj Anand's Untouchable (1935), Khushwant Singh's Train to Pakistan (1956), Rasipuram Krishnaswami Narayan's The World of Nagaraj (1990), and Rohinton Mistry's Family Matters (2002). Roger Fowler has said that literature, as a form of discourse, articulates ideology; it is through linguistic criticism (combination of literary criticism and linguistic analyses) that the ideologies in a literary text are uncovered. Shobhana Chelliah in her study of Indian novels in English concludes that the authors use Indian English (IndE) as a device to characterize buffoons and villains. Drawing upon Fowler's and Chelliah's framework, my investigation employs linguistic criticism of the four novels to expose the ideologies reflected in the use of fictionalized English in the Indian context. A quantitative inquiry based on thirty-five IndE features reveals that the authors appropriate these features, either to a greater or lesser degree, to almost all their characters, suggesting that IndE functions as the mainstream variety in these novels and creating an illusion that the authors are merely representing the characters' unique Indian worldviews. But within this dialect range, the appropriation of higher percentages of IndE features to specific characters or groups of characters reveal …

The purpose of this study was to determine the extent to which faith-based preschools promote spiritual development in preschoolers. The participants in the study were faith-based early childhood teachers and administrators from seven states. Early childhood professionals representing 11 Christian faith traditions completed written surveys or online surveys. A total of 201 faith-based educators completed the survey; 20 respondents participated in semi-structured interviews. The concurrent triangulation mixed-method design provided data on 8 program dimensions which support children's spiritual development: prayer, Bible literacy, worship, building character, service opportunities, assessment, parental involvement and context. I analyzed quantitative data using descriptive and inferential statistics. All items were examined using mean, standard deviation, frequency, and percentages. Qualitative data gathered from semi-structured interviews were coded and analyzed using NVivo8® qualitative analysis software (QSR International, Inc., Cambridge, MA, http://www.qsrinternational.com). From this data I identified the extent to which faith-based preschool programs support children's spiritual development through the practices of prayer, Bible literacy, worship, building character, service opportunities, assessment, parental involvement and context. Data analyses revealed statistically significant differences in faith-based teachers' hours of training in children's spiritual development across all program practice dimensions. A key finding of the study was that training in children's spiritual development …

Early development of O2 chemoreception and hypoxic responses under normoxic (150 mmHg) and chronically hypoxic (110 mmHg) conditions were investigated in Xenopus laevis from hatching to 3 weeks post fertilization. Development, growth, O2 consumption, ventilatory and cardiac performance, and branchial neuroepithelial cells (NEC) density and size were determined. At 3 days post fertilization (dpf), larvae started gill ventilation at a rate of 28 ± 4 beats/min and showed increased frequency to 60 ± 2 beats/min at a PO2 of 30 mmHg. Also at 3 dpf, NECs were identified in the gill filament buds using immunohistochemical methods. Lung ventilation began at 5 dpf and exhibited a 3-fold increase in frequency from normoxia to a PO2 of 30 mmHg. Hypoxic tachycardia developed at 5 dpf, causing an increase of 20 beats/min in heart rate, which led to a 2-fold increase in mass-specific cardiac output at a PO2 of 70 mmHg. At 10 dpf, gill ventilatory sensitivity to hypoxia increased, which was associated with the increase in NEC density, from 15 ± 1 to 29 ± 2 cells/mm of filament at 5 and 10 dpf, respectively. Unlike the elevated rate, cardiac and ventilatory volumes were independent of acute hypoxia. Despite increased cardioventilatory frequency, …

Effective supply chain management gains much attention from industry and academia because it helps firms across a supply chain to reduce cost and improve customer service level efficiently. Focusing on one of the key challenges of the supply chains, namely, demand uncertainty, this dissertation extends the work of Zhao, Xie, and Leung so as to examine the effects of forecasting method selection coupled with information sharing on supply chain performance in a dynamic business environment. The results of this study showed that under various scenarios, advanced forecasting methods such as neural network and GARCH models play a more significant role when capacity tightness increases and is more important to the retailers than to the supplier under certain circumstances in terms of supply chain costs. Thus, advanced forecasting models should be promoted in supply chain management. However, this study also demonstrated that forecasting methods not capable of modeling features of certain demand patterns significantly impact a supply chain's performance. That is, a forecasting method misspecified for characteristics of the demand pattern usually results in higher supply chain costs. Thus, in practice, supply chain managers should be cognizant of the cost impact of selecting commonly used traditional forecasting methods, such as moving …

With the development of free and easy-to-use software programs, blogging has helped turn Web consumers into Web content providers. Blogging provides distinctive insight into comprehending e-consumer behavior explicitly with respect to social networking and information searching behaviors while facilitating a state of flow. The objectives of this study are to identify determinant dimensions of blogging motivations and flow, and to investigate the hypothesized relationships of the motivational blogging behavior. Analyzing data (n = 432) from a southwestern university, results reveal the critical dimensions of motivations, behaviors, and flow in blogging. Upon extending Hoffman and Novak's (1996) flow model, 14 out of 26 hypotheses were confirmed regarding the significant impacts of blogging motivations and flow on blogging behaviors. The findings revealed that the desire for information, enjoyment, and loyalty are the primary drivers for experiential blogging behavior. Specifically, information-seeking is the decisive motivation to urge experiential and e-shopping behavior concurrently. This study shows that indulgence and telepresence in flow might play pivotal mediating roles to promote the goal-oriented e-shopping behavior resulting enjoyment and loyalty-seeking motivations.

The economic disaster known as the Great Depression struck Grayson County, Texas, in 1929, and full economic recovery did not come until the close of World War II. However, the people of Grayson benefited greatly between 1933 and 1946 from the myriad spending programs of the New Deal, the building of the Denison Dam that created Lake Texoma, and the establishment of Perrin Army Air Field. Utilizing statistical data from the United States Census and the Texas Almanac, this thesis analyzes the role of government spending‐federal, state, and local‐in the economic recovery in Grayson County.

Texas textile mills comprise an untold part of the modern South. The bulk of Texas mills were built between 1890 and 1925, a compressed period of expansion in contrast to the longer developmental pattern of mills in the rest of the United States. This compression meant that Texas mill owners benefited from knowledge gained from mill expansion elsewhere, and owners ran their mills along the same lines as the dominant southeastern model. Owners veered from the established pattern when conditions warranted. This case study focuses on three mills in Texas that operated both independently and as a corporation for a total of sixty years. One mill in McKinney dominated the economy of a small town and serves as the primary focus of this paper. A second mill in Waco served a diversified economy in the center of the state; and the third mill, built in Dallas was concentrated in a major city in a highly competitive job market. All three of these mills will illuminate the single greatest difference between Texas mills and mills elsewhere, the composition of the labor force. Women did not dominate the mill labor force in Texas nor did children, except in limited cases, make-up a …

Niels Viggo Bentzon (1919-2000) is the most significant composer in the post-Nielsen period of Danish piano music. Bentzon's Third Piano Sonata, Op.44 was composed in 1946 and is considered by Mark L. Lehmann to be one of the great piano sonatas of the twentieth century. Not only does this sonata reflect Hindemith's ideas, but it also reveals Bentzon's unique style that successively empowers his innovative features. By applying Hindemith's theory, this study offers a way of understanding this piece and demonstrates the relevance of Hindemith's theory as a tool for analyzing the sonata. Chapter 1 presents the significance of the study, the state of research, the purpose of the study, and method. Chapter 2 provides a theoretical analysis of Bentzon's Third Piano Sonata, Op. 44. With a discussion of each movement, this analytical chapter traces Hindemith's influences: Bentzon organizes the four movements with a clear formal structure, a mediant relationship between the first movement and the rest of the movements, and a motivic coherence of each movement. Also, this chapter demonstrates how Bentzon follows Hindemith's way of chord construction and harmonic progression. This chapter provides insight into Bentzon's original style that facilitates an understanding of the tonal organization of each …

Second language (L2) researchers and teachers have increasingly come to believe that using a computer-based corpus can be extremely helpful in the language classroom. The purpose of this study is to examine whether corpora can be used outside of the classroom in order for students to improve their essays independently. No previous study has tried to examine students' essays in relation to corpus use so that this study is exploratory. Seven international students wrote five essays on specific topics and then corrected their errors through corpus research. Two experiments were conducted with different students and followed three steps: receiving information about how to use the BYU COCA, writing and correcting, and interviews with students. I examined quantitatively the number and types of errors that students were able to correct in two experiments and reported qualitatively on students' interview responses.

Many calamities in history like hurricanes, tornado and flooding are proof to the large scale impact they cause to the life and economy. Computer simulation and GIS helps in modeling a real world scenario, which assists in evacuation planning, damage assessment, assistance and reconstruction. For achieving computer simulation and modeling there is a need for accurate classification of ground objects. One of the most significant aspects of this research is that it achieves improved classification for regions within which light detection and ranging (LiDAR) has low spatial resolution. This thesis describes a method for accurate classification of bare ground, water body, roads, vegetation, and structures using LiDAR data and aerial Infrared imagery. The most basic step for any terrain modeling application is filtering which is classification of ground and non-ground points. We present an integrated systematic method that makes classification of terrain and non-terrain points effective. Our filtering method uses the geometric feature of the triangle meshes created from LiDAR samples and calculate the confidence for every point. Geometric homogenous blocks and confidence are derived from TIN model and gridded LiDAR samples. The results from two representations are used in a classifier to determine if the block belongs ground or …

The first part of the paper states the problem of the double bass not being incorporated into the chamber music program at many universities and the resulting lack of skills that can only be developed through this discipline. The double bass is trying to catch up with the other string instruments as it has been historically ignored, misunderstood and not as developed musically and technically. The historical background and current state of research are being examined to understand why this problem occurred in the first place, noting the vast amount of chamber music repertoire that is unknown and identifying some important but underperformed works. Further the pedagogical benefits of playing chamber music are discussed in order to realize the vital importance of integrating the double bass into the curriculum at major universities. Specific examples from the four major style periods are discussed in detail to show the benefits of studying this repertoire. Finally an implementation process is suggested to help change the current state of chamber music neglect as it pertains to the double bass.

Optimal animal welfare has been a long-term goal for captive animal institutions. To measure welfare a definition and identification of elements that make up welfare need to be established. Further, a method to measure welfare's elements that can be implemented into staff's daily routine is necessary to establish baseline levels and track changes in welfare. The goal of the proposed captive animal activity tracking system is to allow for the measurement of each element of welfare quickly, while providing information regarding the animal's current state of welfare and how changes to the animal's environment affect welfare. The data show that this system is effective in revealing behavioral patterns and changes in behavior that occurred in response to environmental changes.

Social stimuli that function as reinforcers for most children generally do not function as reinforcers for children diagnosed with autism. These important social stimuli include smiles, head nods, thumb-ups, and okay signs. It should be an important goal of therapy for children with autism to condition these neutral social stimuli to function as reinforcers for children diagnosed with autism. There is empirical evidence to support both a pairing procedure (classical conditioning) and a discriminative stimulus procedure to condition neutral stimuli to function as reinforcers. However, there is no clear evidence as to the superiority of effectiveness for either procedure. Despite this most textbooks and curriculum guides for children with autism state only the pairing procedure to condition neutral stimuli to function as reinforcers. Recent studies suggest that the discriminative stimulus procedure may in fact be more effective in conditioning neutral stimuli to function as reinforcers for children diagnosed with autism. The present research is a further comparison of these two procedures. Results from one participant support recent findings that suggest the discriminative stimulus procedure is more effective in conditioning neutral stimuli to function as reinforcers. But the results from the other participant show no effects from either procedure, suggesting future …

Existing literature on foreign aid does not indicate what type of political regime is best to achieve human development outcomes or use aid funds more efficiently. I contend that political leaders of different regime types have personal incentives that motivate them to utilize foreign aid to reflect their interests in providing more or less basic social services for their citizens. Using a data set of 126 aid-recipient countries between the years of 1990 and 2007, I employ fixed effects estimation to test the model. The overall results of this research indicate that foreign aid and democratic institutionalization have a positive effect on total enrollment in primary education, while political regime types show little difference from one another in providing public health and education for their citizens.
