Children's spiritual development: Analysis of program practices and recommendations for early childhood professionals.

Children's spiritual development: Analysis of program practices and recommendations for early childhood professionals.

Date: December 2009
Creator: Myers, Joyce Eady
Description: 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 ...

Comparing a discriminative stimulus procedure to a pairing procedure: Conditioning neutral social stimuli to function as conditioned reinforcers.

Comparing a discriminative stimulus procedure to a pairing procedure: Conditioning neutral social stimuli to function as conditioned reinforcers.

Date: December 2009
Creator: Koelker, Rachel Lee
Description: 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 ...

Comparison of IKONOS Derived Vegetation Index and LiDAR Derived Canopy Height Model for Grassland Management.

Comparison of IKONOS Derived Vegetation Index and LiDAR Derived Canopy Height Model for Grassland Management.

Date: December 2009
Creator: Parker, Gary
Description: Forest encroachment is understood to be the main reason for prairie grassland decline across the United States. In Texas and Oklahoma, juniper has been highlighted as particularly opportunistic. This study assesses the usefulness of three remote sensing techniques to aid in locating the areas of juniper encroachment for the LBJ Grasslands in Decatur, Texas. An object based classification was performed in eCognition and final accuracy assessments placed the overall accuracy at 94%, a significant improvement over traditional pixel based methods. Image biomass was estimated using normalized difference vegetation index (NDVI) for 1 meter resolution IKONOS winter images. A high correlation between the sum of NDVI for tree objects and field tree biomass was determined where R = 0.72, suggesting NDVI sum of a tree area is plausible. However, issues with NDVI saturation and regression produced unrealistically high biomass estimates for large NDVI. Canopy height model (CHM) derived from 3-5m LiDAR data did not perform as well. LiDAR typically used for digital elevation model (DEM) production was acquired for the CHM and produced correlations of R = 0.26. This suggests an inability for this particular dataset to identify juniper trees. When points that registered a tree height where correlated with field ...

Cultivating the Ecological Conscience: Smith, Orr, and Bowers on Ecological Education

Cultivating the Ecological Conscience: Smith, Orr, and Bowers on Ecological Education

Date: December 2009
Creator: Hoelscher, David W.
Description: During the past two decades, one of the positive developments in academia has been the emergence of a sizable literature pertaining to ecological education-the theory and practice of preparing children and adults alike for ecologically responsible citizenship. Gregory A. Smith, David W. Orr, and C. A. Bowers are three of the more prolific writers in the field. Smith critiques modern primary and secondary education and argues for, and paints a picture of, an alternative "green pedagogy" that seeks to inculcate in students strong community and ecological values. Orr focuses on the social and ethical problems associated with the environmental crisis and the changes that colleges and universities need to make in order to become propagators of, rather than impediments to, a widespread diffusion of ecological literacy. Bowers emphasizes the role that ecologically problematic modern cultural assumptions play in blinkering the ecological vision of most educational theorists and in preventing the flowering of an eco-justice pedagogy. Each writer seeks the transformation of both education and culture with a view toward realizing ecological sustainability, strong communities, social justice, and moral edification. They neglect or ignore some important subjects, including animal welfare ethics, politics, and corporate influence on governments.

Cultural and Technical Perspectives on Winter Landscape

Cultural and Technical Perspectives on Winter Landscape

Date: December 2009
Creator: Wang, Jing
Description: Winter Landscape is an interactive composition for erhu (Chinese two-stringed fiddle), flute, piano, and Max/MSP interactive computer music system. The total duration of the piece is approximately 15 minutes. Winter Landscape serves to demonstrate one particular approach to exploring the possibilities afforded in an interactive paradigm within a cross-cultural context. The work is intended to convey my personality and identity as a contemporary Chinese composer through diverse cultural and musical influences drawn to this particular piece while creating a balance between traditional and modern sounds. The influences of Chinese philosophy (especially Chán) and the essence of Chinese traditional music play a prominent role as demonstrated in the formation of structures, expressions, and concept of Yun in the work; these influences also play a great role in determining the instrumentation and basic pitch structures of the work. However, this work is equally influenced by techniques and practices of modern Western classical music. These diverse influences hopefully have resulted in a unique work that truly does represent a cross-synthesis of these varying influences. In Winter Landscape, the interaction that takes place between the computer and the live musician is intended to reveal the responsive human/machine relationships. The computer constantly shifts its roles ...

Cyberbullying: Responses of Adolescents and Parents toward Digital Aggression

Cyberbullying: Responses of Adolescents and Parents toward Digital Aggression

Access: Use of this item is restricted to the UNT Community.
Date: December 2009
Creator: Wong-Lo, Mickie
Description: Cyberbullying is a category of bullying that occurs in the digital realm which affects our students at astonishing rates. Unlike traditional bullying, where displays of aggression may be evident to bystanders, the ramification of cyberbullying occurs through unconventional ways (e.g., text messaging; online weblogs; video sharing), which results in many cases being camouflaged by the advancement in technology. Nonetheless, the effects of this digital form of peer aggression can be as detrimental as face-to-face bullying. The characteristics of cyberbullying and its influences on adolescents and parents of adolescents were examined. The data accrued is based on an anonymous survey through one of the following methods: (a) paper-pencil survey for adolescent group with 37-question items on the adolescent questionnaire and (b) web-based survey for the parent group with 22-question items on the parent questionnaire. Each survey was systematically coded according to the participating group and assigned code numbers (i.e., 1 represents adolescent group and 2 represents parent group) was provided to ensure confidentiality of the study. Survey examined individual variables among the two target groups: (a) adolescents between 13 and 17 years of age and (b) parents of adolescents between 13 and 17 years of age. Specifically, individual variables examined include ...

Design and validation of an automated multiunit composting system.

Design and validation of an automated multiunit composting system.

Date: December 2009
Creator: Pickens, Mark Everett
Description: This thesis covers the design of an automated multiunit composting system (AMUCS) that was constructed to meet the experimental apparatus requirements of the ASTM D5338 standard. The design of the AMUCS is discussed in full detail and validated with two experiments. The first experiment was used to validate the operation of the AMUCS with a 15 day experiment. During this experiment visual observations were made to visually observe degradation. Thermal properties and stability tests were performed to quantify the effects of degradation on the polymer samples, and the carbon metabolized from the degradation of samples was measured. The second experiment used the AMUCS to determine the effect of synthetic clay nanofiller on the aerobic biodegradability behavior of poly (3-hydroxybutyrate-co-3-hydroxyvalerate).

Do different political regime types use foreign aid differently to improve human development?

Do different political regime types use foreign aid differently to improve human development?

Date: December 2009
Creator: Phan, Thu Anh
Description: 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.

Does stimulus complexity affect acquisition of conditional discriminations and the emergence of derived relations?

Does stimulus complexity affect acquisition of conditional discriminations and the emergence of derived relations?

Date: December 2009
Creator: Martin, Tiffani L.
Description: 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.

Does the knowledge of unaudited account balances adversely affect the performance of substantive analytical procedures?

Does the knowledge of unaudited account balances adversely affect the performance of substantive analytical procedures?

Date: December 2009
Creator: Pike, Byron J.
Description: Auditors use substantive analytical procedures to make assertions about the adequacy and appropriateness of client balances. The analytical procedure process consists of auditors creating independent account expectations and corroborating unusual fluctuations through obtaining and evaluating additional audit evidence. Prior analytical procedure research has found that knowledge of clients' unaudited account balances biases auditors' expectations towards the current year figures. However, this research has failed to examine the impact of biased expectations on the subsequent stages of analytical procedures. This dissertation assesses the full impact of biased account expectations on auditors' use of analytical procedures. I experimentally test the hypotheses of my dissertation through administering an experiment to senior level auditors. After inducing an account expectation bias that favors the client account balance in half the participants, I examine the auditors' cognitive investigation into an unusual account fluctuation. The results indicate that a biased account expectation negatively affects auditors' judgment quality. In particular, a biased expectation leads auditors to favor hypotheses and additional information that supports the proposition that the client's balance is reasonably stated. Alternatively, auditors with unbiased account expectations are more willing to consider all hypotheses and are able to identify the most pertinent additional information to the decision ...
