Texas Baptists in the twentieth century struggled to overcome prejudice and embrace racial equality. While historians have generally agreed that Baptist leadership in Texas was more progressive in regard to race relations than that of other southern states, Texas Baptists acquiesced to calls for racial justice with great difficulty. This study seeks to analyze the relationship between Texas Baptists' understanding of social Christianity and their views of racial equality. Furthermore, this study seeks to examine the extent to which white Texas Baptists actually changed their racial views and incorporated African Americans into their church services following the civil rights movement. An analysis of the racial transformation of one of Texas' most famous Baptists, W. A. Criswell, and the history of the Christian Life Commission, which is the ethical arm of the Baptist General Convention of Texas, provides great insight in to the racial progress made by Texas Baptists in the twentieth century. As Texas Baptists enter the twenty-first century and encounter a large and growing Hispanic population, the findings of this study will render aide to those who wish to embark on a new future by learning from the mistakes of their past.

Animals are commonly trained to perform behaviors during routine husbandry procedures. However, some husbandry procedures have aversive consequences when the real procedure is performed. This commonly results in loss of the trained behavior. The present study assessed whether maintaining the antecedent environmental stimulus conditions between appetitive and aversive outcomes would prevent this effect and, conversely, whether adding a stimulus discrepancy would facilitate this effect. Three domestic rats served as participants in a multiple baseline across participants design with multi-element components. All three rats stopped performing a trained behavior when a discrepant stimulus reliably predicted an aversive outcome. In addition, all three rats continued to perform the same behavior when antecedent environmental stimulus conditions were consistent between aversive and appetitive outcomes. Results are discussed in terms of practical implications for behavior change agents and conceptual implications for learning theory.

How do the content and writing style of people who drink alcohol beverages stand out from non-drinkers? How much information can we learn about a person's alcohol consumption behavior by reading text that they have authored? This thesis attempts to extend the methods deployed in authorship attribution and authorship profiling research into the domain of automatically identifying the human action of drinking alcohol beverages. I examine how a psycholinguistics dictionary (the Linguistics Inquiry and Word Count lexicon, developed by James Pennebaker), together with Kenneth Burke's concept of words as symbols of human action, and James Wertsch's concept of mediated action provide a framework for analyzing meaningful data patterns from the content of blogs written by consumers of alcohol beverages. The contributions of this thesis to the research field are twofold. First, I show that it is possible to automatically identify blog posts that have content related to the consumption of alcohol beverages. And second, I provide a framework and tools to model human behavior through text analysis of blog data.

Online instruction is becoming increasingly common at universities; however, there is little single subject research concerning the effectiveness of the online lecture format. We investigated whether online lecture could replace in-class lecture in two sections of an undergraduate Introduction to Behavior Analysis course without detrimentally affecting student learning. Using an adapted alternating treatments design, online and in-class lecture formats were counterbalanced across the two course sections. Experimenters collected data on lecture attendance/access, percent correct on the weekly quiz, and student report on lecture format preference. The data show that, within the context of this class, students performed equally in the weekly quiz regardless of lecture format; further, that this is consistent when looking at individual student data and mean data. However, although students stated a preference for online lecture in the questionnaire, a greater percentage of students attended in-class lecture than accessed online lecture.

Experimenters evaluated the effects of a homework session on undergraduate students' homework performance through an adapted alternating treatments design in two introduction to behavior analysis courses. Several participants attended homework sessions; however, homework submission and homework mastery did not vary as a function of homework session attendance or availability. Homework submission remained high throughout the experiment regardless of attendance at or availability of a homework session. Many participants responded that they were not interested in or did not need homework sessions. Participants who attended homework sessions rated them as neutral or helpful overall, with longer time and different time as the most common suggestions for improvement.
