Racial slavery was a critical element in the cultural development of the Choctaws and was a derivative of the peculiar institution in southern states. The idea of genial and hospitable slave owners can no more be conclusively demonstrated for the Choctaws than for the antebellum South. The participation of Choctaws in the Civil War and formal alliance with the Confederacy was dominantly influenced by the slaveholding and a connection with southern identity, but was also influenced by financial concerns and an inability to remain neutral than a protection of the peculiar institution. Had the Civil War not taken place, the rate of Choctaw slave ownership possibly would have reached the level of southern states and the Choctaws would be considered part of the South.

Voluntarily child free (VCF) individuals face stigmatization in a pronatalist society that labels those who do not want children as deviant. Because of this stigmatization, VCF couples face privacy issues as they choose to reveal or conceal their family planning decision and face a variety of reactions from social network members. Therefore, communication privacy management and communication accommodation theory was use to examine this phenomenon. Prior research found two different types of VCF couples: grounds-based and grounds-free. Grounds-based individuals cite medical or biological reasons for not having children, while grounds-free individuals cite social reasons for not having children. The purpose of this study is to examine how grounds-based and grounds-free VCF couples manage their disclosure of private information and how social network members react to their family planning decision. Findings revealed that grounds-free individuals are more likely to engage in the self-defense hypothesis and grounds-based individuals are more likely to engage in the expressive need hypothesis. Grounds-based individuals were asked about their decision in dyadic situations, whereas grounds-free individuals were asked at group gatherings. Additionally, social network members used under-accommodation strategies the most frequently and grounds-free individuals experienced more name calling than grounds-based. Finally, while grounds-free individuals experienced non-accommodation and …

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.

As the current body of instructional communication research focuses primarily on the relationship between teacher and learner, three studies investigating the relationship between learners were completed in order to better understand how student motivation and learning are influenced by learner-to-learner immediacy behaviors within the college classroom environment. Study I resulted in an extensive list of both positive and negative verbal and nonverbal immediacy behaviors commonly used by learners. Study II required the comparison of the behaviors identified in study one to existing measures of teacher to learner immediacy behaviors, producing a new measure focusing on learner-to-learner immediacy. Following a pilot survey, the reliability of this new measure was determined through face validity and factor analysis, producing the Learner-to-Learner Immediacy Behavior Scale. In Study III, the Learner-to-Learner Immediacy Behavior Scale was combined with Christophel's 1990 Immediacy Behavior Scale, Cognitive Learning Scale, Affective Learning Scale, and Trait and State Motivation Scales and administered to 273 undergraduate students to test the affects of common learner-to-learner immediacy behaviors on student state motivation, affective learning, and perceptions of cognitive learning loss. Multiple regression analyses indicated learner-to-learner immediacy as functioning similarly to teacher-to-student immediacy when mediated through state motivation in its influence on student affective learning …

Early and intensive behavioral intervention outcome research includes descriptions of intervention variables that may increase treatment success. This study was designed to develop an observation system that incorporates and expands on some of these variables. Measures include the number of interventionist teaching units, types of skills addressed during instruction, consequences programmed by interventionists, and engagement with teaching materials. This system allowed for a view of the differences in teaching behaviors among the participants. It is proposed that this observation system is a start toward standardized intervention measures that can be applied to evaluate varied treatment models. Such standardization can help in ensuring that all children have access to evidence-based services.

A child's ability to learn in school and school performance are affected by various factors. Variables that affect learning and academic performance in 46 children, 4 - 7 years old, were examined. Children, parents, and teachers completed questionnaires rating children's attitudes and behavior toward school. Children completed a computerized matching-to-sample (MTS) task. The MTS trained the children to form 3 stimulus classes. One stimulus class included three arbitrary stimuli, the others contained a positively or negatively valenced stimulus, a school-related stimulus, and an arbitrary stimulus. Class formation performance was assessed. Rate of learning predicted attitudes toward school, school attitudes predicted academic performance; however a hypothesized mediation effect of attitudes was not demonstrated. No significant differences in rate of forming stimulus classes containing emotionally valenced and school stimuli were found. Future directions for intervention in the early education of students who have poor attitudes toward school are discussed.

Research has consistently shown that intimate partner homicide (IPH) rates have been on a steady downward decline over the past two decades. A relatively recent movement in IPH research, however, has emphasized the need for further dissecting the aggregate trends by factors such as gender, race, and victim-offender relationship. In response to these issues, this study looks at the relationship between IPHs and factors such as gender, race, and age. The present study explores officially reported IPH cases in Dallas, Texas between the years 1990-1997. Specific attention will be paid to the victim's and suspect's age, race, and gender. The findings of the study will assist in identifying significant characteristics of these IPH incidents which may lead to a greater understanding of the types of relationships in which IPH is more likely to occur. Studying the relationship between IPHs and these factors, as this research aims to do, is important to understanding what IPH incident characteristics need more attention to help prevent future incidents from occurring. As a result of this research, a better understanding of whether IPH may occur in certain types of relationships will be reached and then can be further utilized to educate.

The Picture Exchange Communication System (PECS) has been used with children with autism and other developmental disabilities as an alternative to vocal communication. Some researchers have reported rapid acquisition of picture-exchange requesting as well as increased vocal speech and increased spontaneous social interactions following PECS training. Earlier research has found that although 3 children with autism learned to exchange pictures for preferred items during PECS training, requesting topographies did not change and vocal speech did not increase after PECS training. The present study evaluated the effects of PECS training on requesting topographies, especially vocal speech, with 3 participants with autism and mental retardation. Only one participant maintained picture-exchange requesting, and none of the participants showed an increase in vocal speech during probe sessions conducted after each PECS training phase.

This study explored the state of art education in Turkey as revealed by pre-service art education university instructors, and the potential of incorporating visual culture studies in pre-service art education in Turkey. The instructors' ideas about visual culture, and popular culture, the impact it might have, the content (objects), and the practices within the context of Turkey were examined. Visual culture was examined from an art education perspective that focuses on a pedagogical approach that emphasizes the perception and critique of popular culture and everyday cultural experiences, and the analysis of media including television programs, computer games, Internet sites, and advertisements. A phenomenological human science approach was employed in order to develop a description of the perception of visual culture in pre-service art education in Turkey as lived by the participants. In-person interviews were used to collect the data from a purposive sample of 8 faculty members who offered undergraduate and graduate art education pedagogy, art history, and studio courses within four-year public universities. This empirical approach sought to obtain comprehensive descriptions of an experience through semi-structural interviews. These interviews employed open-ended questions to gather information about the following: their educational and professional background; their definitions of art education and …

Despite having produced an impressive body of work and having been well-received in his lifetime, the career of nineteenth-century American expatriate artist Walter MacEwen has received virtually no scholarly attention. Assimilating primary-source materials, this thesis provides the first serious examination of MacEwen's life and career, thereby providing insight into a forgotten episode in American art.

As more toddlers are being diagnosed with autism there is an increased need for very early intervention. Preliminary research on interventions suggests toddlers can make important developmental progress and that parents can be part of the intervention process. The purpose of this study was to systematically replicate a parent training program reported by Alai-Rosales et al. (2009). Specifically, the present study taught parents a set of teaching strategies that included arranging the environment, setting up learning opportunities, and using positive reinforcement. Baseline-intervention conditions were replicated across four parent-toddler dyads in order to assess the effects of training on parent and child behaviors. Results indicated increases in parent teaching behaviors, the child targeted behavior (facial orientation), as well as a non-targeted skill, joint attention. Findings are discussed in relation to the challenges of intervention and considerations for future research.

The goal of this research was to determine if there are significant differences in the attribution styles for positive and negative events between students of differing ability and the correlation of these attribution styles to hopefulness. The study examined twelfth grade advanced placement (AP N = 45) students and twelfth grade students with documented learning differences enrolled in college preparatory classes (CP-LD N = 14). Both groups of students came from high socioeconomic backgrounds. The students' internal attributions related to hopefulness were measured with the Hope Scale (Snyder, 1994) which assesses the constructs of agency (will), pathway (way), and produces an overall hopefulness score. Results indicate that AP and CP-LD students had similar measures of internal attribution for positive events, but significantly distinct measures of internal attribution for negative events. However, the AP students show no statistically significant difference from CP-LD students in their measures of agency, pathway, or overall hopefulness.

This study is a comparative analysis of the personality characteristics of a sample of World of Warcraft players (n = 147) and a large normative sample (n = 20,993). The 120-item International Personality Item Pool, based on the five factor model, is used. Independent t-tests were conducted and statistical significance was found for some factors; however, the effect sizes were small, indicating a limited practical difference between the two groups.

A longitudinal study of infants and their mothers was conducted to explore the development of imitation and approximations to imitation. During a 10-minute unstructured play session, researchers observed two mother-infant dyads once per week for twelve weeks, while they played at home. The data presented represents infants between the ages 5 and 34 weeks. The methodology employed was based on the methods described by Hart and Rilsey (1999). Observations were coded based on the topography of the mother's and infant's behavior and included vocalizations, facial movements, motor movements, and object manipulation. The data are analyzed and discussed in terms of its relevance to autism intervention.

The purpose of this study is to investigate the effectiveness of a treatment package to teach a child with autism to willingly accept skin care products conducive to health and normal everyday living. The current study uses graduated exposure, modeling and contingent social attention to teach the child to accept the application of skin care products previously avoided. Results of the study showed that the participant tolerated criterion amounts of all target stimuli with both experimenter and parent. Follow-up probes revealed maintenance of the behaviors with only two out of the three target skin care products.

Web-based homework systems are becoming more common in general chemistry as instructors face ever-increasing enrollment. Yet providing meaningful feedback on assignments remains of the utmost importance. Chemistry instructors consider completion of homework integral to students' success in chemistry, yet only a few studies have compared the use of Web-based systems to the traditional paper-and-pencil homework within general chemistry. This study compares the traditional homework system to four different Web-based systems. Data from eight, semester classes consisting of a diagnostic pre-test, final semester grades, and the number of successful and unsuccessful students are analyzed. Statistically significant results suggest a chemistry instructor should carefully consider options when selecting a homework system.

Over-the-air programming systems for wireless sensor networks have drawbacks that stem from fundamental limitations in the hardware used in current sensor nodes. Also, advances in technology make it feasible to use capacitors as the sole energy storage mechanism for sensor nodes using energy harvesting, but most current designs require additional electronics. These two considerations led to the design of a new sensor node. A microcontroller was chosen that meets the Popek and Goldberg virtualization requirements. The hardware design for this new sensor node is presented, as well as a preliminary operating system. The prototypes are tested, and demonstrated to be sustainable with a capacitor and solar panel. The issue of capacitor leakage is considered and measured.

Interest in a multiracial society has increased in recent years and including on racism and prejudice and in the propensity to stereotype out-groups. Theories on racism help explain the dominant group's prejudice toward subordinate groups. Yet they only explain why dominant group members stereotype subordinates or if the dominant group's propensity to stereotype is different from that of subordinate groups. Recent assimilation theories suggest that some minorities are assimilating with Whites but Blacks are not undergoing assimilation. Classic assimilation theory suggests that when a subordinate group assimilates with the dominant group then they will also take on the dominant group's values and beliefs, including their prejudices and propensities to stereotype. The use of racial stereotypes in support of the assimilation of a minority group has not been tested. Results from the LSAF national survey provide support for Asians to be assimilating with Whites. However, Hispanics do not appear to be taking on Whites' propensity to stereotype, contradicting the prediction that Hispanics are assimilating with Whites.

American artist James Rosenquist is best known for his Pop Art paintings, which existing scholarship has studied in regard to its formal features and social and cultural significance. Rosenquist's manner of working, specifically his process, remains understudied. Focusing on three paintings and three corresponding collages, President Elect (1960-61, 1964), Star Thief (1980), and The Stowaway Peers Out at the Speed of Light (2000), this thesis considers features of Rosenquist's studio practice to propose a new interpretation involving the representational status and significance of the artist's collages and paintings that is elucidated by French theorist Jean Baudrillard's concept of the simulacrum. Additionally, the thesis addresses the treatment of Rosenquist's collages and paintings in publications and exhibitions since 1992 by suggesting how Baudrillard's ideas about the simulacrum clarify the museological narrativizing and consumption of the artist's work.

Electronic surveillance for foreign intelligence purposes was largely unregulated prior to 1978. The Foreign Intelligence Surveillance Act of 1978 (hereinafter "FISA") was enacted to implement a judicial authorization process for foreign intelligence electronic surveillance that would effectively balance competing needs for national security and civil liberty under the Fourth Amendment. This study examines the evolution of FISA and its effectiveness under the Fourth Amendment, as assessed by federal reviewing courts and scholars since the statute's enactment. The study concludes that the FISA electronic surveillance authorization process has been effective in providing a constitutional mechanism to obtain foreign intelligence information.

Blair sent British troops to join U.S. forces in the invasion of Iraq in 2003 at great political cost to himself. What motivated him to take this step? Sources for this work include: autobiographies and biographies of individuals close to Blair; journal and newspaper articles and monographs on this topic; Prime Minister's speeches and press conferences. Part one is comprised of five chapters including the Introduction; Blair's years at school; Blair's early political career; and From Parliament to Prime Minister. Part two includes four chapters that analyze motivating factors such as, Anglo-American Relations; Blair's personality, faith, and his relationship with Gordon Brown; and finally, Blair's perception of Britain's Manifest Destiny. All of these factors played a role in Blair's decision.
