Evaluating the Effects of Public Postings on Energy Conservation Behavior at a Public University
This study evaluated the effects of public postings on energy conservation behavior at a public university, using a multiple baseline design across three settings; bathrooms break rooms, and conference rooms. The behavior of building occupants was recorded to assess the frequency at which those individuals would turn lights off upon exiting an unoccupied room. The independent variables implemented by experimenters (light-switch plate stickers and laminated signs) had little to no effects on cumulative instances of lights turned off however, the installation of motion sensor lights produced better results. Across all conditions, lights were turned off most frequently in conference rooms (65% of observations) followed by break rooms (9% of observations), and bathrooms (3% of observations). digital.library.unt.edu/ark:/67531/metadc84184/
Evaluating the Effects of Video Modeling on the Frequency of Staff Use of Socially Embedded Consequences
Previous research reports that individuals working with children with autism can positively affect social behavior through the use of socially embedded consequences. There is no research on training teachers to use socially embedded consequences. The current study had three purposes: to evaluate the effects of video modeling on teachers' embedded consequences, to evaluate the addition of feedback to increase effectiveness, and to evaluate the effects of the teacher's use of socially embedded consequences on other teacher behaviors. Results indicate that video modeling alone was not sufficient in changing teacher behavior and that the addition of feedback was necessary for meaningful teacher behavior change. Additionally, the increased used of socially embedded consequences had positive effects on teacher social engagement and indices of interest. A discussion of the results and suggestions for future research is also provided. digital.library.unt.edu/ark:/67531/metadc177267/
Evaluating the Feasibility of Accelerometers in Hand Gestures Recognition
Access: Use of this item is restricted to the UNT Community.
Gesture recognition plays an important role in human computer Interaction for intelligent computing. Major applications like Gaming, Robotics and Automated Homes uses gesture recognition techniques which diminishes the usage of mechanical devices. The main goal of my thesis is to interpret SWAT team gestures using different types of sensors. Accelerometer and flex sensors were explored extensively to build a prototype for soldiers to communicate in the absence of line of sight. Arm movements were recognized by flex sensors and motion gestures by Accelerometers. Accelerometers are used to measure acceleration in respect to movement of the sensor in 3D. Flex sensors changes its resistance based on the amount of bend in the sensor. SVM is the classification algorithm used for classification of the samples. LIBSVM (Library for Support Vector Machines) is integrated software for support vector classification, regression and distribution estimation which supports multi class classification. Sensors data is connected to the WI micro dig to digitize the signal and to transmit it wirelessly to the computing device. Feature extraction and Signal windowing were the two major factors which contribute for the accuracy of the system. Mean Average value and Standard Deviation are the two features considered for accelerometer sensor data classification and Standard deviation is used for the flex sensor analysis for optimum results. Filtering of the signal is done by identifying the different states of signals which are continuously sampled. digital.library.unt.edu/ark:/67531/metadc699862/
Evaluating the Habitat Requirements of the Golden Orb Mussel (Quadrula Aurea) for Conservation Purposes
Many freshwater mussels are imperiled, due to a number of interrelated factors such as habitat alteration, degradation of water quality, and impoundments. The Golden Orb mussel (Quadrula aurea, I. Lea, 1859) is endemic to the state of Texas and is currently a candidate for the endangered species list, as the number of known populations has been declining in recent years. Little is currently known about Q. aurea aside from basic distribution data. This study is focused on evaluating a combination of macro-habitat and micro-habitat variables to determine their influence on the distribution and density of this species. Macro-habitat variables, including dominant land cover, surface geology, and soil erodibility factor, did not have a significant relationship with mussel distributions. The best model of micro-habitat variables that impacts the Q. aurea distributions is comprised of relative substrate stability (RSS) at moderate flows and current velocity at low flows. For all mussel species in this study, current velocity at low flows is the primary variable that influences distribution. Q. aurea are associated with habitats where larger sediment particles (large gravel and cobble) help to stabilize the substrate in areas with higher current velocities. An understanding of the preferred habitats for Q. aurea can be used to help focus conservation efforts and practices. digital.library.unt.edu/ark:/67531/metadc271827/

Evaluating the Role of C-reactive Protein on Cognition and Depressive Symptoms Among Women by Mexican American Ethnicity
C-reactive protein (CRP) is a protein found in the blood that is synthesized by the liver and has been extensively studied due to its role in inflammatory and atherosclerotic processes. The importance of this biomarker in its role in vascular risk factors is increased with several lines of evidence pointing to its association with cognitive decline. The association between CRP and depression has been increasingly analyzed by various cross-sectional studies. The research between CRP and depressive symptoms in older women has yet to generate consistent trends. In the present study, a series of regression analyses was used to explore the association between CRP and both cognitive function and depressive symptomatology among a group of rural-dwelling women. Associations were evaluated through the use of data from Project FRONTIER, a rural-based research looking at both physical and cognitive aspects of health in rural-dwelling adults and elders. Comparisons were made between Mexican American women and a group of non-Hispanic Caucasian women. CRP was a significant independent predictor of total depression (beta = -.11, t = -1.99, p =.048). CRP was also a significant independent predictor of symptoms associated with meaningless within depression (beta = -.16, t = -2.94, p =.004). Contrary to prediction, CRP was not a significant independent predictor of overall cognitive function or performance in five specific cognitive domains. There is still needed evaluation on racial/ethnic differences present in regard to the impact of varied health factors on mental health within a culturally rich, rural cohort. It is recommended that future studies utilize standardized measurement of cognitive function to facilitate a more thorough understanding and comparison of change in this particular population. digital.library.unt.edu/ark:/67531/metadc700036/
Evaluating the Role of Design in the Apparel Industry in the United States
The purpose of this study was to better understand the role of design in the product development process in the apparel industry in the United States, looking for variations in how design is used in the industry. In order to obtain a snapshot of the fashion design industry, creativity, originality, innovation, and product development were examined, as well as corporate culture and strategic orientation. The study also sought to examine pedagogical strategies based on these findings. A mixed methods approach, consisting of an on-line survey and interviews, was employed. The findings suggest variations in the role of design based on the time design-department employees spent on creative tasks. These variations were examined and industrial and pedagogical implications are explored. The significance of this study relates to the findings of the importance of creativity in the product development process of the apparel industry in the United States, as well as considerations for pedagogical strategies. digital.library.unt.edu/ark:/67531/metadc700003/
Evaluating the Scalability of SDF Single-chip Multiprocessor Architecture Using Automatically Parallelizing Code
Advances in integrated circuit technology continue to provide more and more transistors on a chip. Computer architects are faced with the challenge of finding the best way to translate these resources into high performance. The challenge in the design of next generation CPU (central processing unit) lies not on trying to use up the silicon area, but on finding smart ways to make use of the wealth of transistors now available. In addition, the next generation architecture should offer high throughout performance, scalability, modularity, and low energy consumption, instead of an architecture that is suitable for only one class of applications or users, or only emphasize faster clock rate. A program exhibits different types of parallelism: instruction level parallelism (ILP), thread level parallelism (TLP), or data level parallelism (DLP). Likewise, architectures can be designed to exploit one or more of these types of parallelism. It is generally not possible to design architectures that can take advantage of all three types of parallelism without using very complex hardware structures and complex compiler optimizations. We present the state-of-art architecture SDF (scheduled data flowed) which explores the TLP parallelism as much as that is supplied by that application. We implement a SDF single-chip multiprocessor constructed from simpler processors and execute the automatically parallelizing application on the single-chip multiprocessor. SDF has many desirable features such as high throughput, scalability, and low power consumption, which meet the requirements of the next generation of CPU design. Compared with superscalar, VLIW (very long instruction word), and SMT (simultaneous multithreading), the experiment results show that for application with very little parallelism SDF is comparable to other architectures, for applications with large amounts of parallelism SDF outperforms other architectures. digital.library.unt.edu/ark:/67531/metadc4673/

Evaluating Tree Seedling Survival and Growth in a Bottomland Old-field Site: Implications for Ecological Restoration
In order to assess the enhancement of seedling survival and growth during drought conditions, five-hundred bare-root seedlings each of Shumard oak (Quercus shumardii Buckl.) and green ash (Fraxinus pennsylvanica Marsh.) were planted each with four soil amendments at a Wildlife Management Area in Lewisville, Texas. The treatments were a mycorrhizal inoculant, mulch fabric, and two superabsorbent gels (TerraSorb® and DRiWATER®). Survival and growth measurements were assessed periodically for two years. Research was conducted on vegetation, soil, and site history for baseline data. Both superabsorbent gels gave significant results for Shumard oak survival, and one increased green ash diameter. For overall growth, significant results were found among DRiWATER®, mycorrhizae, and mulch treatments. digital.library.unt.edu/ark:/67531/metadc3998/
An Evaluation and Analysis of Teachers' Codes of Ethics
The problem of this thesis was to study the codes of thirteen other states and, in addition, the codes of Texas and the National Education Association, were selected because of the realization that a very small per cent of the teaching profession knows of the existence of such codes and a still smaller per cent knows anything at all of the content of the codes. digital.library.unt.edu/ark:/67531/metadc53408/
An Evaluation and Comparison of the Music Hour Series and the World of Music Series as Appropriate Basic Texts for Elementary Music
An important and unending responsibility of the music teacher is the competent evaluation of available basic text-series. It seems obvious that before any text-series, or any single book, is adopted for use in the public school music classes, a process of assessing the available series or single volumes should precede the final decision and purchase. Since a thorough search in music education literature has failed to reveal any set of formal rules of analysis, the writer has thought it possible to use those general principles recommended by two authoritative sources, The Psychology of School Music Teaching by Mursell and Glenn, and Music in the Grade Schools by Gehrkens in collaboration with personal ideas obtained from professional study of music teaching and experience as a music teacher. digital.library.unt.edu/ark:/67531/metadc699738/

The evaluation, development, and application of the correlation consistent basis sets.
Employing correlation consistent basis sets coupled with electronic structure methods has enabled accurate predictions of chemical properties for second- and third-row main group and transition metal molecular species. For third-row (Ga-Kr) molecules, the performance of the correlation consistent basis sets (cc-pVnZ, n=D, T, Q, 5) for computing energetic (e.g., atomization energies, ionization energies, electron and proton affinities) and structural properties using the ab initio coupled cluster method including single, double, and quasiperturbative triple excitations [CCSD(T)] and the B3LYP density functional method was examined. The impact of relativistic corrections on these molecular properties was determined utilizing the Douglas-Kroll (cc-pVnZ-DK) and pseudopotential (cc-pVnZ-PP) forms of the correlation consistent basis sets. This work was extended to the characterization of molecular properties of novel chemically bonded krypton species, including HKrCl, FKrCF3, FKrSiF3, FKrGeF3, FKrCCF, and FKrCCKrF, and provided the first evidence of krypton bonding to germanium and the first di-krypton system. For second-row (Al-Ar) species, the construction of the core-valence correlation consistent basis sets, cc-pCVnZ was reexamined, and a revised series, cc-pCV(n+d)Z, was developed as a complement to the augmented tight-d valence series, cc-pV(n+d)Z. Benchmark calculations were performed to show the utility of these new sets for second-row species. Finally, the correlation consistent basis sets were used to study the structural and spectroscopic properties of Au(CO)Cl, providing conclusive evidence that luminescence in the solid-state can be attributed to oligomeric species rather than to the monomer. digital.library.unt.edu/ark:/67531/metadc5484/

An Evaluation Model for Identifying Lewisville and San Angelo, Texas, as Senior Ready Communities
This research portrays a paradigm for the assessment of aging services to support populations aging in place. The dissertation was designed to establish a model to identify and evaluate senior ready communities. Area specific social programs and services are identified. In order to meet the growing needs of aging populations, the dynamic representation of existing services and the need for services that could be developed in certain communities require reevaluation in current planning, restructuring, and/or community development. digital.library.unt.edu/ark:/67531/metadc12195/
Evaluation of a Common Carp (Cyprinus carpio L.) Exclusion and Trapping Device for Use in Aquatic Plant Founder Colony Establishment
The focus of this study was to design and evaluate a trapping system that would reduce populations of common carp within water bodies in conjunction with establishment of native aquatic macrophytes founder colonies. A pond study and field study were conducted. A pond study was performed at the Lewisville Aquatic Ecosystem Research Facility, located in Lewisville, Texas, followed by a field study within a constructed wetland located in southern Dallas, Texas. For the pond study, twelve funnel traps were constructed (four reps of each type: control, dual-walled and ring cage). Two anti-escape devices were tested with funnels including steel fingers and hinged flaps. Ring cage and dual-walled treatments were planted using native pondweeds, while controls were left unplanted (additional bait and a drift fence scenarios were also tested). Common carp were introduced into the study pond. Chi-square statistical analyses were utilized and showed ring cage treatments using fingers as well as the use of a drift fence to be most effective. Following completion of the pond study, the two most effective treatments (controls and ring cages) were tested within the Dallas, Texas wetland; no carp were caught during the field test. digital.library.unt.edu/ark:/67531/metadc6038/

Evaluation of a Constructed Wetland to Reduce Toxicity from Diazinon at the Pecan Creek Wastewater Treatment Plant, Denton, TX
The City of Denton Pecan Creek Wastewater Treatment Facility has periodically failed effluent toxicity testing. A Toxicity Identification Evaluation has determined that Diazinon in the effluent is contributing to the observed toxicity. Chlorpyrifos is also implicated as a factor. The City of Denton constructed a half acre experimental wetland to remove Diazinon related toxicity. Results from spiking and microcosm experiments indicate that the wetland can reduce the Diazinon. digital.library.unt.edu/ark:/67531/metadc279107/

Evaluation of a Master of Divinity Program in a Theological Seminary
The objective of this research project was to evaluate the effectiveness of the M.Div. program of Alliance Bible Seminary, Hong Kong. The research was designed for evaluation based solely upon the perceptions of the participant (graduate). The research identified and described the graduates enrolled, assessed perceived career development and attainment, and measured the degree of satisfaction experienced by the graduates who have matriculated from the degree program. A questionnaire was mailed to obtain the necessary data from the graduates of the M.Div. program of Alliance Bible Seminary. The questionnaire which was used was adapted from a previously used one used in the study of graduate educational programs. It has been tested in two other previous studies and was deemed effective. In order to verify its effectiveness in the Eastern context, a pilot test was conducted before the formal research, and the adapted questionnaire was found effective. Responses to the questionnaire were coded and the SPSS system was used to analyze the data. Tables and figures were constructed showing frequencies and significant differences where they occurred. Generally, the graduates at Alliance Bible Seminary were very satisfied with their educational experiences. Both males and females indicated that they would choose the same path again, and would recommend the program to others. The graduates were having full-time employment in the field of Christian ministry, and were positively attaining their career goals. The steps leading to the degree at Alliance Bible Seminary were perceived as very helpful and useful, not just the course work and independent reading, but also extre-curricular activities such as voluntary work on campus, Student Evangelistic Band, and interaction with faculty. Some aspects of the program need improvement and consolidation, such as freshmen advising in the majors, course work in the core, quality of instruction, varieties of course offered, and access to computing resources. A special concern should be made on spiritual formation activities. Over half of the respondents (55%) were not satisfied with this. This evaluation was the first of its kind in the history of the seminary. It emphasized the importance of keeping the institution responsive to the rapidly changing conditions of the society, especially in Hong Kong and China, where the focus of Christian ministry will be in the new century. Hopefully, this research project will kindle a series of research efforts that in the end will help the seminary creating an evaluation system within the institution, so that the institution is kept sensitive to the changing environment and can improve its programs accordingly. digital.library.unt.edu/ark:/67531/metadc2711/

Evaluation of a Training Package for Teaching Social Skills in an Inclusionary Preschool Environment
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. digital.library.unt.edu/ark:/67531/metadc4872/

An Evaluation of an Intensive Toilet Training Model
The current evaluation assessed the effectiveness of an intensive toilet training procedure for three young boys with autism. The evaluation extended the work of LeBlanc et al. (2005) by assessing parents’ preference to include the usage of urine alarm and positive practice. In addition, we collected descriptor data on challenging behaviors. All three parent participants’ elected not to use the urine alarm and one parent elected to discontinue the implementation of positive practice techniques. Researchers chose a nonconcurrent multiple baseline across participants design to evaluate the effects of the intervention. All three child participants’ increased successful self-initiations for the toilet and decreased accidents across home and clinic settings. Findings suggest that clinicians should partner with parents to develop individualized toileting interventions that are acceptable and effective. digital.library.unt.edu/ark:/67531/metadc804964/

Evaluation of City of Denton Sub-Watershed by Benthic Macroinvertebrate Field Experimental Approach
Access: Use of this item is restricted to the UNT Community.
In this study, two different field experiments were designed to assess the relative influence of urbanization on benthic communities. During spring and summer, four urban and one reference sites from Denton County, Texas were selected for benthic macroinvertebrate evaluation. Statistically significant differences in colonized benthic macroinvertebrate taxa on artificial substrates were observed among the four urban sites and the reference site. Oligochaetes and chironomids were the dominant taxa at all sites. Identification of chironomid larvae at the subfamily and genus level to detect differences between sites had higher statistical power than the evaluation based on total chironomids. At the reference site, Caenis, Cladotanytarsus, Orthocladius, and Ceratopogonidae were the dominant taxa, while the urban sites were dominated by Dero, Physella, Ancylidae, Chironomus, Dicrotendipes, Glyptotendipes, Polypedilum, Pseudochironomus, Stenochironomus, and Tanytarsus. These differences may have been dependent upon differences in hydrologic regime and water quality between sites. Significant differences (ANOVA, p < 0.01) in water quality parameters (alkalinity, hardness, nitrates, phosphates, chlorides, sulfates, calcium, magnesium, potassium, and triazine) were found among water samples collected from the reference and urban sites. During the transfer period, most of the Ephemeroptera and Trichoptera taxa and a few other taxa disappeared from artificial substrates that were colonized at the reference site and then moved to the urban sites. Also, local abundant taxa from the urban site significantly (t test, p < 0.05) increased in number on the transferred artificial substrates. Seasonal differences in colonization patterns were also observed between the spring and summer experimental periods, which indicate that temporal variation is equally important, as is the anthropogenic effect in benthic community evaluation. Field survival and growth experiments using Erpetogomphus designatus larvae were designed to detect differences between evaluated sites. Larvae were collected from the reference site, measured in the laboratory, and exposed at the urban sites for six weeks in using specially designed cages. The exposed larvae demonstrated a higher mortality rate at the urban sites compared to the reference site. digital.library.unt.edu/ark:/67531/metadc5314/
