Interactions of equivalence and other behavioral relations: Simple successive discrimination training.
The experimenter asked if documented equivalence class membership would influence the development of shared discriminative stimulus function established through simple successive discrimination training. In Experiment 1, equivalence classes were established with two sets of 9 stimuli. Common stimulus functions were then trained within or across the equivalence classes. Greater acquisition rates of the simple discriminations with stimuli drawn from within the equivalence classes were observed. In Experiment 2, a third stimulus set was added with which no equivalence relations were explicitly trained. The findings of Experiment 1 were replicated, but the Set 3 results were inconsistent across subjects. The outcomes of the two experiments demonstrate that equivalence classes have an effect on other behavioral relations which requires further investigation.

An Actor-Partner Interdependence Model of Attachment Processes, Conflict Resolution, and Psychological Abuse on Relationship Quality in a Community Sample of Heterosexual Couples.
The purpose of this study is to determine whether adult attachment style, psychological abuse in the marriage, conflict resolution strategies, and gender are associated with relational quality in childless couples in the early years of their marriage. Data were collected from 92 married couples who were recruited from university campuses, churches, and community organizations through e-mails, flyers, newspaper advertisements and mailings. Conceptualizing the interdependence of dyadic data from the actor-partner interdependence model (APIM), multilevel linear modeling (MLM) was used to analyze differences within and between couples. It was hypothesized that higher levels of attachment anxiety or avoidance, psychological abuse, and maladaptive conflict resolution strategies would be associated with lower relational quality. Results indicated that attachment avoidance had stronger associations with relational quality than did attachment anxiety, and that higher levels of attachment avoidance were associated with lower relational quality. Additionally, findings indicated a direct negative relationship between both actor and partner psychological abuse and the actor's relational quality. The discussion section addresses strengths and limitations of the present study as well as directions for future research.

The Effects of Professional Learning Communities on Student Achievement
The purpose of this study was to examine data from the Early Childhood Longitudinal Study: Kindergarten Class of 1998-99 (ECLS-K) report, identify questions and statements that correlate to the dimensions of professional learning communities (PLCs), and determine the effect PLCs have on student achievement based on the ECLS-K data. In addition, the rationale for doing this research was to measure growth in student achievement over time. A multilevel growth model was used for this research. Univariate analysis was conducted in order to reveal frequencies and percentages associated with teacher responses. Bivariate analysis was applied in order to determine the inter-correlations between the fourteen variables. Once the inter-correlations were determined from the bivariate analysis, principal component analysis was applied in order to reveal the theoretical relationship between the variables. Through the use of principal components a set of correlated variables is transformed into a set of structure coefficient: support and collaborative. Finally, a multilevel growth model was used in order to determine the effect that each variable within the support and collaborative structure coefficients had on student achievement over time. This study revealed a number of variables within the ECLS-K report that correspond to the dimensions of PLCs have a statistically …

Process of identifying a guiding theory: An exploratory study.
At the University of North Texas, and as per the Council for Accreditation of Counseling and Related Educational Programs (CACREP) standards, masters students in counselor training are required to choose a personal theoretical approach to the counseling process. The purpose of this study was to investigate an experimental counseling theory identification procedure compared to the traditional procedure of helping students identify a personal theory of counseling. The investigation assessed the effect on 1) counselor self-report of confidence in theoretical orientation selection/identification, and 2) the degree to which a student consistently identifies, conceptualizes and utilizes a particular counseling theoretical approach. Volunteer participants (n=35) were recruited from three sections of COUN 5660 and were randomly drawn to group assignment within each class. The experimental condition focused on exploration of personal beliefs related to human nature, maladjustment and the nature of change as a basis for theory selection. The comparison group received the standard theory selection activities. The TCQ and TOPS-R were used to examine the effect of treatment and were administered at three points of time. Data was analyzed using a split plot ANOVA to examine group differences, changes across time, and the possible interaction of change with group membership. Statistical and …

An Evaluation of the Effects of Two Different Role Play Formats on the Outcomes of a Parent Training Curriculum
The current study was designed to replicate and extend previous research on the effectiveness of behavioral parent training. Specifically, the effectiveness of the Behavior Management and Parenting Services (BMAPS) curriculum in teaching parents to exhibit a set of parenting skills and respond accurately to a multiple choice examination about positive parenting techniques was evaluated. In addition, the curriculum was revised so that the relative effectiveness and acceptability of two role play formats could be assessed. The outcomes of the study showed an improvement in the participants' ability to identify correct answers on a multiple choice examination and apply the parenting skills taught in class within a role play format; results pertaining to the efficacy of each role play format were less conclusive.

Analysis of Qualified Immunity for Texas Public School Professional Employees as Interpreted by the Texas Courts
This dissertation analyzed Texas appellate court decisions relating to whether educators' actions were incident to or within the scope of duties and involved the exercise of judgment or discretion in cases involving defamation, motor vehicle exceptions, and excessive force in discipline exceptions. The questions addressed were: (1) How have the Texas appellate courts interpreted Texas Education Code Section 22.051 in litigation against teachers and school administrators for defamation? (2) How have the Texas appellate courts interpreted Texas Education Code Section 22.051 in litigation against teachers and school administrators for injury to students when plaintiffs have sued Texas educator under the motor vehicle exception to the educator immunity law? (3) How have the Texas appellate courts interpreted Texas Education Code Section 22.051 in litigation against teachers and school administrators under the excessive force in discipline exception to the educator immunity law? This dissertation utilized legal research as its methodology. Chapter 3 examines literature with regard to qualified immunity for Texas public school professional employees and discusses the limitations placed upon qualified immunity. Chapter 4 is a comprehensive study of the cases decided by Texas courts involving alleged defamation of students or others by teachers and school administrators. Chapter 5 is a …

State Level Causes of Terrorism: Limits on Political Expression
Expanding on prior research into the state level causes of terrorism, I argue that state repression and limited state capacity reduces opportunities for non-violent political expression and increases the utility of terrorism. I also argue that economic freedom can is a form of political expression that can dissipate political grievances. While previous authors analyzed some of these variables separately using data on transnational attacks, I created a complete model incorporating the three categories of variables and tested my hypotheses using data that includes both domestic and transnational attacks. I use regression analysis for hypothesis testing and find support for the three primary contentions of this thesis and conclude that limits on political expression increase the likelihood nations will experienced increased levels of terrorism.

The Impact of IT Capability on Employee Capability, Customer Value, Customer Satisfaction, and Business Performance
This study empirically examines the impact of IT capability on firms' performance and evaluates whether firms' IT capabilities play a role in improving employee capability, customer value, customer satisfaction, and ultimately business performance. The results were based on comparing the business performance of the IT leader companies with that of control companies of similar size and industry. The IT leader companies were selected from the Information Week 500 list published annually from 2001 to 2004. For a company to be selected as IT leaders, it needed to be listed at least twice during the period. Furthermore, it had to be listed in the American Customer Satisfaction Index (ACSI) so that its customer satisfaction level could be assessed. Standard & Poor's Compustat and the ACSI scores were used to test for changes in business performance. The study found that the IT leaders had a raw material cost measured by cost-of-goods-sold to sales ratio (COGS/S) than the control companies. However, it found no evidence that firms' IT capability affects employee capability, customer value, customer satisfaction, and profit. An important implication from this study is that IT becomes a commodity and an attempt to gain a competitive advantage by overinvesting in IT may …

Saying Sorry: Conflict Atrocity and Political Apology
This study proposes and tests a comprehensive theory detailing the motivations behind political apologies. A brief survey of the literature shows a field rich in case studies but lacking in rigorous scientific analysis. The theory presented proposes a three-level examination of political apology at the state, dyadic, and system levels and incorporates the effects of culture, conflict, and the nature of the international system into analysis. This study makes use of a new dataset recording the occurrence of political apologies for interstate conflict atrocities from 1900 to 2006. The results suggest that the existing literature, while rich, does not account for all the motivating factors behind apology. The results also confirm that political apology is a creation of the modern era and a result of the liberalization of the international system. In conclusion, paths for future research are suggested and the advent of a global "age of apology" is confirmed.
