The purpose of the study was to investigate the effects of play materials on the interactions between a child with autism and her sibling. Three conditions were assessed: open choice, materials chosen by the child with autism, and materials chosen by the typically developing sibling. Within each activity, measures of social interactions were assessed. Results of the assessment showed that more interactions occurred with a material chosen by the child with autism. After sibling training (targeting specific teaching skills), social interactions remained highest in the condition with materials chosen by the child with autism. The results are discussed in terms of a material assessment to optimize sibling training conditions and the importance of sibling relationships.

During the spring 2004 a pilot school recycling program was implemented within Robert E. Lee Elementary. The primary goal of the program was to determine how recycling education in the school would affect curbside recycling rates within the surrounding community. The program was a cooperative effort between the University of North Texas, City of Denton Solid Waste Department and Keep Denton Beautiful. Throughout the first months of the study during the spring 2004, an increase in curbside recycling within the Robert E. Lee Elementary attendance zone was observed, with a dramatic decrease in participation over the summer and a rapid increase once again during the second full semester of the study. In a survey conducted with 3rd and 5th grade students at the pilot project school, most students expressed positive attitudes about recycling. Students whose survey responses indicated a high level of knowledge about what could be recycled were 37% more likely to claim to recycle regularly, than those students that scored low on the knowledge portion of the survey. Although the total amount of waste generation (recyclable and non-recyclable) at Robert E. Lee Elementary did not decrease during the study, the campus was able to divert recyclable material from …

Although Turkey is a country with strong social cohesion, figures of runaway children in Turkey are increasing dramatically. This research focused on the factors that cause children to run away and on interaction programs to intervene and/or prevent this problem. Until recently, Turkish family life was able to avoid such problems, but with the effect of westernization and social mobility in Turkey, the basic family structure has become more like the family structure in the western countries. Studies reveal that runaway episodes happen in all families regardless of such factors as economic, race, or geographic situations. Teenagers run away for several reasons; however, early intervention is highly suggested by studies to mitigate the problem. Although, parent-child conflict plays a significant role as a reason for youth leaving home, on the other hand family interaction still remains the best alternative to the problem.

Bad Poetry and Other Short Stories is a collection of social, political, and religious commentary. The last three stories are also commentary from a non-fiction perspective.

Pat M. Neff served as governor of Texas from 1921 to 1925, a period marked by political conflict between rural conservatives and urban progressives. Neff, a progressive, found himself in the middle of this conflict. Neff supported prohibition, declared martial law in the oil boomtown of Mexia, and faced the rise of the Ku Klux Klan as a political force in Texas. Though often associated with the Klan, Neff did not approve of the organization and worked against it whenever possible. During the Railroad Shopmen's Strike of 1922, Neff stalled the federal government in its demand he send troops to Denison just long enough to win re-nomination. William Jennings Bryan mentioned Neff as a possible candidate for the presidency in 1924, but he pursued a back-door strategy that alienated his political base among Texas Democrats.

Ecological restoration is quickly becoming a major approach to how humans interact with the natural world. Some view restoration as another land management technique on par with conservation and preservation. Others view it as a way to make reparations for our misdeeds and to reincorporate humans into the natural world. Ideas regarding restoration from key academics and restorationists are evaluated here. Their views have set the stage for the contemporary paradigm. Values that may be attributed to restoration and received from it are evaluated. I discuss my own reservations regarding potential problems with the product and practice of restoration. What is at stake regarding the involvement of people in restoration is examined, focusing on the different impacts volunteers and paid workers have on the value of the practice and outcome of the product.

This study evaluated the utility of a structured descriptive assessment (SDA) as an alternative method of functional assessment. Initially, an analogue functional analysis, conducted to assess the problem behavior of two adults with developmental disabilities, produced inconclusive results. Subsequently, SDAs was conducted in the individuals' natural environment with the direct-contact caregivers acting as therapists. This assessment manipulated antecedent variables similarly to the analogue functional analysis but allowed for consequences to occur naturally. The results from SDAs suggested that problem behaviors, for both participants, were occasioned by removal of personal items and maintained by their return. Treatments based on the results of SDAs were implemented in a reversal design and resulted in a notable reduction in the occurrences of problem behavior for both participants. These outcomes suggest that SDA procedures may be useful when results from the analogue functional analysis are inconclusive.

Disease prevalence varies with geographic location. This research pursues a medical geographic perspective and examines the spatial variations in disease patterns between Obuasi, a gold mining town and Asankrangwa, a non gold mining town in Ghana, West Africa. Political ecology/economy and the human ecology frameworks are used to explain the prevalence of diseases. Mining alters the environment and allows disease causing pathogens and vectors to survive more freely than in other similar environments. Certain diseases such as upper respiratory tract infections, ear infections, sexually transmitted diseases such as HIV/AIDS and syphilis, certain skin diseases and rheumatism and joint pains may have a higher prevalence in Obuasi when compared to Asankrangwa due to the mining in Obuasi.

This thesis provides the first formal and phenomenological analysis of the architecture in Paquimé, otherwise known as Casas Grandes, Chihuahua, Mexico. The eastern and western halves of the city are divided by a stone wall and reservoirs. The monuments on the east are rectilinear, puddled adobe structures used primarily for domestic and manufacturing purposes. The buildings on the west, on the other hand, are open earth mounds lined in stone for public displays. This thesis analyzes each building individually, the relationship of the structures to one another, and the entire layout of Paquimé in order to better understand Paquimian visual culture.

The following premise is based on the ideas of social theorists who have contributed to understanding the importance of image in society. This proposal argues that political participation is susceptible to exploitation in the form of conspicuous consumption as defined by Thorstein Veblen. The analyses that follow will test the degree to which Americans who demonstrate more traditional forms of conspicuous consumption also tend to show more activity in political venues. While the correlation of these two variables is not sufficient to demonstrate cause and effect, it may be significant enough to attract more researchers to this question: are Americans using political involvement to positively influence the way that their social status is perceived by others?

This study focuses on the amount of coverage given by four major tabloid newspapers-Demos, Zambeze, Savana and Domingo-to the candidates of the major political parties Renamo and Frelimo, during the 2004 presidential race. The number of stories of both parties in those newspapers were counted and calculated by chi-square to determine how much one party was covered than the other identifying signs of balance or bias. The research showed that there was a significant result of 42 percent of likelihood that stories in the four newspapers would either be about Frelimo or Renamo. However, the study also revealed that Frelimo was the party covered most often by Demos, Zambeze and Savana while Renamo was covered most often by Domingo.

The transtheoretical model has a substantial history of measuring the change process. Hemphill and Howell validated the Stages of Change Scale (SOCS) on adolescent offenders. The current study expands their research by developing an additional component of the TTM, the Decisional Balance Scale for Adolescent Offenders (DBS-AO). This measure assesses movement through the stages of change and provides insight into mechanisms through which adolescent offenders attempt to change their criminal behaviors. Two hundred thirty-nine adolescent offenders at the Gainesville State School completed the SOCS, DBS-AO, Paulhus Deception Scales (PDS), and the Antisocial Process Screening Device (APSD). The study found the DBS-AO is psychometrically sound, demonstrates excellent reliability and has an underlying three-factor solution: Cons, Pros-Self, and Pros-Others. Offenders in the early stages of change scored significantly higher on the Cons scale. Offenders actively changing their behavior scored significantly higher on the Pro-Self and Pros-Other scales.

The Aubrey Clovis site is one of the oldest late-Pleistocene sites in North America, dated to ~11,550 B.P., and contains two camps with a range of lithic debitage, numerous hearths, and excellent faunal preservation. Couched in rules of classification, a series of artifact distributions are analyzed with qualitative and quantitative techniques, including maps produced in a geographic information system (GIS) and tests of artifact associations using correlation statistics. Theoretical and methodological protocols are promoted to improve spatial analysis in archaeology. The results support the short-term occupation interpretation and expose the differential patterning among bone, stone, and raw materials distributions. The spatial structure and diverse content of the site challenge models of Clovis-age people as strictly big game hunters.

We examined the claim that equivalence classes contain all positive elements in a reinforcement contingency by asking whether negative stimuli in a reinforcement contingency will also form an equivalence class, based on their shared function as S-minus stimuli. In Experiment 1, 5 subjects were tested for equivalence for positive and negative stimuli. Testing of positive stimuli preceded testing of negative stimuli. Two of five subjects demonstrated equivalence for positive stimuli, and three subjects demonstrated equivalence for negative stimuli. In Experiment 2, order of testing was reversed. Four of six subjects demonstrated equivalence for positive stimuli, and none demonstrated equivalence for negative stimuli. In Experiment 3, positive and negative stimuli were tested together. Only one of five subject demonstrated equivalence for positive and negative stimuli. These data suggest that negative stimuli may enter an equivalence class, and so Sidman paradigm should be expanded. Order of testing was found as a meaningful variable.

This thesis discusses the relatively new approach of art education, by paralleling it to Marxist ideology on art. The Dallas Arts District is one example of a city where museum art education is in conflict: being adopted more vigorously by some and with less acceptance by others. In order to provide a glimpse into the museum ideology of downtown Dallas, previous schools of thought regarding the role of curators and the introduction of educators into museums will be detailed, as well as conflicts between these two factions. The following questions will be addressed: Is museum art education truly a movement which strives to infuse the American culture with a greater appreciation of art? Is there a link to overcoming Marx's key issue of class? How is the movement affecting the Dallas Arts District and to what extent is museum art education being utilized within this forum? Is the emphasis toward museum art education greater in Dallas than in other large cities across the United States, and if so, how has that affected the cities' patrons?

The National Institute of Child Health and Human Development (NICHD) is funding and supporting a longitudinal study of Early Child Care. Beginning in 1991, data was collected from ten sites across the United States and included 1,364 families with a newborn child. This study used the NICHD Early Child Care data set to investigate characteristics of teachers that provide childcare in a daycare-like setting or childcare centers. Specifically, the relationship between early childhood teacher endorsement of developmentally appropriate belief systems and teacher education in early childhood were examined to determine their potential influence on the teachers' developmentally appropriate classroom practices, global rating of classroom quality, and child cognitive abilities. These relationships were examined at two time periods- at child age 36 months and child age 54 months. The results indicated that many of these relationships were significant. Interestingly, many of the significant findings were present only at child age 54 months.

The present study contributes an apparatus and research paradigm useful in generating human performances sensitive to concurrent schedules of reinforcement. Five participants produced performances observed to be under temporal and ratio control of concurrent fixed interval-fixed ratio schedules. Two aspects of interaction between FI and FR schedules were distinguishable in the data. First, interaction between two schedules was observed in that changes in the value of one schedule affected behavior reinforced on another schedule. Second, switching from one pattern to the other functioned as an operant unit, showing stability during schedule maintenance conditions and sensitivity to extinction. These effects are discussed in the context of current views on behavior under concurrent schedules of reinforcement, and some implications for the conceptualization, measurement, analysis, and treatment of complex behavior are presented.

This study examines the effects of accuracy-only training and fluency training on retention of material learned. Two adolescent participants with traumatic brain injuries were taught to name 2 sets of lowercase Greek letters. Each of the 2 sets consisted of 7 letters. Practice and rate of reinforcement were controlled for in this study. Fluency trained letters showed higher retention (percent correct during retention checks) than the accuracy-only trained letters.

The effects of two consequence delivery methods on task acquisition were evaluated within a multi-element design. A typical 3 year-old child and a 4 year-old child with autism participated in this study. The task for both children was to select a picture after the experimenter said its name. The consequence in one condition consisted of the experimenter handing the edible item to the children. The consequence in the other condition consisted of the children retrieving the edible item directly from the apparatus, located in a crevice underneath each picture. Results show slightly quicker acquisition in the condition where children retrieved the edible consequence. However, it is possible that other variables had greater influence on the task acquisition.

Small-scale, conservation-based agrarianism provides a model for sustainable human habitation within heterogeneous landscapes. Thoreau's Transcendentalism and the historical roots of American Agrarianism are explored as influences for wilderness preservation and the New Agrarian movement. Idealizing a distant wilderness too often means overlooking the ecological and socio-economic environment where people live. Middle landscapes between nature and culture, or between wilderness and cities, can either increase or reduce ecological and social functioning within the landscape matrix. Managing middle landscapes by agrarian principles helps move both nature and culture towards ecological, economic, and social sustainability. This thesis ends with a discussion of agrarian themes, such as supporting decentralized local economies and increasing community connectivity, applied in urban, rural, and wilderness landscapes.

The focus of environmental philosophy has thus far heavily depended on the extension of rights to nonhuman nature. Due to inherent difficulties with this approach to environmental problems, I propose a shift from the contemporary language of rights and duties to the concept of character development. I claim that a theory of environmental virtue ethics can circumvent many of the difficulties arising from the language of rights, duties, and moral claims by emphasizing the cultivation of certain dispositions in the individual moral agent. In this thesis, I examine the advantages of virtue ethics over deontological and utilitarian theories to show the potential of developing an ecological virtue ethic. I provide a preliminary list of ecological virtues by drawing on Aristotle's account of traditional virtues as well as on contemporary formulations of environmental virtues. Then, I propose that certain types of rules (rules of thumb) are valuable for the cultivation of environmental virtues, since they affect the way the moral agent perceives a particular situation. Lastly, I offer preliminary formulations of these rules of thumb.

Effective training procedures are necessary when teaching behavior analytic techniques because the techniques are so complex and precise; and there is a correlation between the changed skills in the trainees to be beneficial to the client. Instructors who may previously exhibit effective teaching techniques in a one-to-one setting may not exhibit those techniques in an inclusive setting. This study examines the effects of a training package and an instruction on the performance of experienced instructors, and desired responding from both preschool-aged children with autism and typically developing peers. The training took place with 3 triads of one instructor, one child with autism, and one peer in a center-based inclusionary preschool. Instructor skills targeted were prompt and consequence delivery for the target social skills, getting attention and responding to peers. Corroborative data on children's responding were obtained.

The current study attempted to show the relationship of paternal sensitivity and maternal sensitivity and their possible influences on child cognitive and behavioral development. This study used data collected as part of the National Institute for Child Health and Human Development (NICHD) Study of Early Child Care, which is a longitudinal, multi-site study. Correlation and regression analyses were computed to examine relationships between the variables at child age 6 and 36 months. Results indicated paternal sensitivity was a significant positive predictor of child cognitive abilities and a negative predictor of both fathers' reports of children's externalizing and internalizing behaviors. Maternal sensitivity was a significant negative predictor of mothers' reports of children's externalizing behaviors. Interpretations of these results and directions for future research are discussed.

Nanoindentation is a widely used technique to measure the mechanical properties of films with thickness ranging from nanometers to micrometers. A much better understanding of the contact mechanics is obtained mostly through finite element modeling. The experiments were modeled using the software package Nano SP1 that is based on COSMOSM™ (Structural Research & Analysis Corp, www.cosmosm.com), a finite element code. The fundamental material properties affecting pile-up are the ratio of the effective modulus to yield stress Eeff/σ and the work hardening behavior. Two separate cases of work hardening rates were considered; one with no work hardening rate and other with a linear work hardening rate. Specifically, it is observed that pile up is large only when hf/hmax is close to one and degree of work hardening rate is small. It should also be noted that when hf/hmax < 0.7 very little pile-up is observed no matter what the work-hardening behavior of the material. When pile-up occurs the contact area is greater than that predicted by the experimental methods and both the hardness and modulus are overestimated. In this report the amount by which these properties are overestimated are studied and got to be around 22% approx. Bluntness of the tip …
