The Effects of Perceptual Motor Enrichment Upon a Six Year Old with Cerebellar Brain Damage

The Effects of Perceptual Motor Enrichment Upon a Six Year Old with Cerebellar Brain Damage

Date: August 1986
Creator: Shepardson, Nina F. (Nina Fredrica)
Description: This study involved the effects of a perceptual motor enrichment program upon the motor skills of a six year old boy with cerebellar brain damage, who, with a control group of ten normal six year olds, was given a pre-test of motor skills. He and a child from the control group participated in a perceptual-motor enrichment program. The motor skills of both subjects were tested halfway through the program. Following the program, the experimental child, the control child, and the control group were post-tested on their motor skills. The testings showed that the greatest gains in motor skills were obtained by the experimental child, followed by the control child. The control group displayed little increase in motor skill performance.

Effects of Performance Levels of Subject Matter Experts on Job Analysis Outcomes

Effects of Performance Levels of Subject Matter Experts on Job Analysis Outcomes

Date: December 1997
Creator: Boyd, Charlotte Friedersdorff
Description: Much research has been undertaken to determine how Subject Matter Expert characteristics affect job analysis outcomes. The current study seeks to discover if performance levels are related to current incumbents ratings of their positions. A group of 114 corporate associates, from two administrative positions, served as Subject Matter Experts (SME) for this study. Separate job analyses for each position were conducted using the Job Analysis Task Checklist. The results for each job were analyzed to determine if SME performance levels affected job analysis outcomes. The results for both jobs showed that there were very few differences in job analysis results as a function of SME performance levels.

Effects of Peripheral Nerve Injury on the Cells of the Dorsal Root Ganglion: a Role for Primary Cilia

Effects of Peripheral Nerve Injury on the Cells of the Dorsal Root Ganglion: a Role for Primary Cilia

Date: December 2012
Creator: Smith, Sarah K.
Description: Primary cilia are ubiquitous sensory organelles found on most cell types including cells of the dorsal root ganglia (DRG). The DRG are groups of peripheral neurons that relay sensory information from the periphery to the CNS. Other cell types in the DRG include a type of glial cell, the satellite glial cells (SGCs). The SGCs surround the DRG neurons and, with the neurons, form functional sensory units. Currently are no reports describing the numbers of DRG cells that have cilia. We found that 26% of the SGCs had primary cilia. The incidence of cilia on neurons varied with neuron size, a property that roughly correlates with physiological characteristics. We found that 29% of the small, 16% of the medium and 5% of the large neurons had primary cilia. Primary cilia have been shown to have a role in cell proliferation in a variety of cell types. In some of the cells the cilia mediate the proliferative effects of Sonic hedgehog (Shh). In the CNS, Shh signaling through primary cilia affects proliferation during development as well as following injury, but no studies have looked at this function in the PNS. The SGCs and neurons of the DRG undergo complex changes following ...

Effects of Picture Exchange Training on Communication Topographies

Effects of Picture Exchange Training on Communication Topographies

Date: May 2009
Creator: Haray, Aimee H.
Description: 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.

Effects of Plasma, Temperature and Chemical Reactions on Porous Low Dielectric Films for Semiconductor Devices

Effects of Plasma, Temperature and Chemical Reactions on Porous Low Dielectric Films for Semiconductor Devices

Date: December 2010
Creator: Osei-Yiadom, Eric
Description: Low-dielectric (k) films are one of the performance drivers for continued scaling of integrated circuit devices. These films are needed in microelectronic device interconnects to lower power consumption and minimize cross talk between metal lines that "interconnect" transistors. Low-k materials currently in production for the 45 and 65 nm node are most often organosilicate glasses (OSG) with dielectric constants near 2.8 and nominal porosities of 8-10%. The next generation of low-k materials will require k values 2.6 and below for the 45 nm device generation and beyond. The continuous decrease in device dimensions in ultra large scale integrated (ULSI) circuits have brought about the replacement of the silicon dioxide interconnect dielectric (ILD), which has a dielectric constant (k) of approximately 4.1, with low dielectric constant materials. Lowering the dielectric constant reduces the propagation delays, RC constant (R = the resistance of the metal lines; C = the line capacitance), and metal cross-talk between wires. In order to reduce the RC constants, a number of low-k materials have been studied for use as intermetal dielectrics. The k values of these dielectric materials can be lowered by replacing oxide films with carbon-based polymer films, incorporating hydrocarbon functional groups into oxide films (SiOCH ...

The Effects of Positive Behavioral Supports in Schools since the Implementation of the Individuals with Disabilities Education Act of 1997 based on 2001 SLIIDEA Data

Date: August 2009
Creator: Miller, Cindy
Description: Congress in 1997 recognized that there were some issues and concerns that had emerged surrounding the Individuals with Disabilities Education Act (IDEA) and sought to address these issues and concerns by mandating a national evaluation on the implementation and progress toward improving outcomes for students with disabilities. The Study of the State and Local Implementation of the Individuals with Disabilities Education Act was designed to address how the amendments of IDEA were being implemented by states, school districts, and schools. This mixed methods study examined the first year of data collected from the six-year Study of the State and Local Implementation of IDEA (SLIIDEA) and analyzing 20 case studies that used interviews of special education personnel and principals, conducted at the local school level. Data from the national survey were examined in light of findings from the case studies. The case studies brought out the varying opinions on implementation success at the local level. Further case studies for each year of the study would be helpful in determining the level of implementation locally and the significant insights of local school personnel on whether these initiatives have worked.

The Effects of Positive Emotion, Negative Emotion, Flourishing, and Languishing on Cardiovascular Risk

The Effects of Positive Emotion, Negative Emotion, Flourishing, and Languishing on Cardiovascular Risk

Date: August 2010
Creator: Purdum, Michael B.
Description: Positive psychology has led a movement that concentrates on positive characteristics. The current study examined the relationship between positive emotions, negative emotions, flourishing, languishing, and cardiovascular functioning. The study uses guided imagery to help participants recall a negative emotional event and positive emotional event in a counterbalanced order. The reverse order allowed us to examine the differential contributions of stress buffering versus facilitated recovery effects to higher levels of heart rate variability (HRV). The study also examined the relationship between mental health categories and known cardiovascular disease risk. Univariate analysis of variance revealed that positive emotions can serve as a stress buffer and dampen cardiovascular responses to a negative event. Also, analysis revealed a trend for the prediction that positive emotions can facilitate cardiovascular recovery following a negative event. Exploratory analysis did not reveal differences between a facilitated recovery group and a buffering group for cardiovascular measures. Future studies should include tighter control to help compare the differential influences of stress facilitation and stress buffering on cardiovascular functioning. The results from the study indicate that it is still too early to tell whether mental health buffers those individuals from developing CVD, and to answer whether languishing increases the risk of ...

The Effects of Positive Reinforcement on the Self-Concept of Children in a Classroom

The Effects of Positive Reinforcement on the Self-Concept of Children in a Classroom

Date: August 1974
Creator: Kalish, Robert B.
Description: This study tests whether positive reinforcement consisting of a positive word, eye contact, and a smile would improve the self-concept of students. Sixty boys and girls in two sixth-grade classes were given an adaptation of Gordon's, How I See Myself scale. A baseline consisting of positive reinforcements given by the teacher to the students was taken. Then a positive reinforcement schedule was instituted by the sixth-grade teacher. The experimental group of thirty students received a mean of 24.78 positive reinforcements per class; the control group received a mean of 1.1 positive reinforcements. The subjects were again given the HISM scale, and no significant score differences were found between the experimental group and control group.

The Effects of Practice Procedure and Task Difficulty on Tonal Pattern Accuracy.

Date: May 2003
Creator: Cahn, Dan
Description: The study investigated the relative effectiveness of different proportions of time spent on physical and mental practice, in the context of a music performance of a tonal pattern over harmonic progressions of two difficulty levels. Using a sampling without replacement procedure, sixty undergraduate students were assigned to four practice groups partially blocked for musical instrument. The groups included a physical practice group, a mental practice group and two combined mental and physical practice groups in the proportions of (a) 66% physical and 33% mental, and (b) 33% physical and 66% mental. Each subject performed a pretest, a 3 minute practice session, and a posttest on both harmonic progressions. Presentation of the harmonic progressions were counterbalanced to control for practice effects All pre- and posttests were recorded and scored according to number of note errors. An ANCOVA procedure using pretest scores as covariates revealed that: (a) there were no differences between the different practice groups on the measure of note errors, (b) there was a significant difference between the two harmonic progressions on the measure of note errors, such that performance on the easy progression was significantly better than performance on the hard progression, and (c) there was a significant interaction ...

The Effects of Pre-Kindergarten on Spanish-Speaking Bilingual Students Taking the Third Grade TAKS Reading Test

The Effects of Pre-Kindergarten on Spanish-Speaking Bilingual Students Taking the Third Grade TAKS Reading Test

Date: December 2008
Creator: Ringhauser, John T.
Description: The purpose of this dissertation is to provide research and data examining the impact of pre-kindergarten on Spanish-speaking ESL students on the third grade TAKS Reading test scores. The two questions that guided this study are: (1) As measured by the third grade TAKS reading test, what is the relationship between those limited english proficient (LEP) Spanish-speaking children who attended a pre-kindergarten program and those who did not attend a pre-kindergarten program? and (2) As measured by the third grade TAKS Reading test, how do the test scores of those LEP Spanish-speaking third graders who attended the district's pre-k program in 2000-2001 and testing in 2005, differ from those who attended the district's pre-k program in 2001-2002 and testing in 2006? The research study used a quantitative methodology designed as causal-comparative analysis. Independent t-tests were used to determine if there were any significant differences in test scores of third graders between the two groups of students. Although the results of the statistical analysis revealed some isolated statistically significant differences between those Spanish-speaking bilingual students who attended pre-kindergarten and those who did not, the data showed no real differences in the test scores of those students.

The Effects of Premenstrual Syndrome Symptomatology on Marital Satisfaction

Access: Use of this item is restricted to the UNT Community.
Date: August 2003
Creator: Rodgers, Glenda S.
Description: Many women reporting PMS symptoms state their symptoms affect their mood, social, and family functioning. This study attempted to provide clinicians with information to assist in psychotherapeutic intervention, by determining the effect PMS has on marital satisfaction. Nineteen female subjects reporting PMS symptoms and their partners completed the study. The Marital Satisfaction Inventory - Revised (MSI-R) and the Moos Menstrual Distress Questionnaire-Form T (MDQ-form T) were used to determine if the nineteen couples reported marital distress as a result of the women's cyclical premenstrual symptoms. The results of the study suggested that the women and their partners, report high levels of marital distress that is not reflective of the cyclical nature of the PMS symptomatology. Scores on the MSI-R for the subjects and their partners indicated the couples perceived level of distress in the t-50 to t-70 range on scales 3-8 is consistent throughout the menstrual cycle. The couples reported higher levels of marital distress than would be the expected norm, suggesting that PMS may be a contributing factor to the level of distress they reported experiencing. This study did not include a control group, which would have provided a norm for couples who do not report PMS by which ...

The Effects of Price and Durability on Individual Discounting Functions When Purchasing Hypothetical Goods in a Simulated Internet Store

Date: August 2012
Creator: Gesick, Jeffrey Glen
Description: Online shopping has rapidly expanded in the last decade. Online shopping necessarily imposes delays on all transactions. Behavior analysis has long studied the effects of delay on choice. Additionally, a number of researchers are beginning to study consumer behavior using a behavior-analytic approach. The current study attempted to extend research focusing on consumer behavior in online contexts. The experimenters attempted to evaluate whether goods acquire functional properties and whether these properties influence consumer choice. The researchers were specifically interested in studying acquisition costs and durability and in simulating a natural online shopping environment. Results from the current study extend the findings showing that delay and price influence choice. The data from the current study provide mixed evidence for control by item durability.

The Effects of Priming and Contingent Attention on Novel Play Episodes in a Child with Autism

The Effects of Priming and Contingent Attention on Novel Play Episodes in a Child with Autism

Date: August 2002
Creator: Josendale, Julianne R.
Description: This study evaluated the effects of priming and contingent attention procedures on play variability in a child with autism. During baseline, numbers of novel play episodes, different play episodes, and actions occurred at low rates. Priming procedures did not produce desired change. When contingent attention was implemented, significant increases occurred in novel play episodes, different actions, and different play episodes. These results show that attention contingent on variable play episodes can increase the number of novel responses to play materials. The results are discussed within the context of treatment and future research.
