The Determinants and Consequences of Empathic Parenting: Testing an Expansion of Belsky's Model of Parenting Using SEM

The Determinants and Consequences of Empathic Parenting: Testing an Expansion of Belsky's Model of Parenting Using SEM

Date: May 2010
Creator: Morse, Margaret K.
Description: An understanding of factors that enhance empathic parenting behaviors is of considerable importance to the study of child development and to the development of parenting interventions to promote child adjustment. Moreover, gaining a better understanding of the factors that predict empathic parenting with older children is of interest since most research examining parental empathy focuses on infants. These were the goals of the current study. Guided by Belsky's 1984 process model of the determinants of parenting that impact child development, an expanded model of the determinants of parenting is proposed that includes various parent, child, and contextual factors of influence. Using data from a community sample, a partial least squares path analysis approach was employed to test the model's strength in predicting empathically attuned parenting with children ages 5 to 10 years and, ultimately, the child's psychoemotional functioning. Results support the expanded model; however, a reduced model was found to be superior and revealed unique relationships between the determinants of parenting. Specifically, a parent's psychoemotional functioning and childrearing beliefs and attitudes were found to be critical to the parent's ability to engage in empathic parenting behaviors. Other parent factors such as the parent's developmental history of abuse, maladaptive personality traits, ...

Determination of the Optimal Number of Strata for Bias Reduction in Propensity Score Matching.

Determination of the Optimal Number of Strata for Bias Reduction in Propensity Score Matching.

Date: May 2010
Creator: Akers, Allen
Description: Previous research implementing stratification on the propensity score has generally relied on using five strata, based on prior theoretical groundwork and minimal empirical evidence as to the suitability of quintiles to adequately reduce bias in all cases and across all sample sizes. This study investigates bias reduction across varying number of strata and sample sizes via a large-scale simulation to determine the adequacy of quintiles for bias reduction under all conditions. Sample sizes ranged from 100 to 50,000 and strata from 3 to 20. Both the percentage of bias reduction and the standardized selection bias were examined. The results show that while the particular covariates in the simulation met certain criteria with five strata that greater bias reduction could be achieved by increasing the number of strata, especially with larger sample sizes. Simulation code written in R is included.

Determining Factors that Influence High School Principal Turnover Over a Five Year Period

Determining Factors that Influence High School Principal Turnover Over a Five Year Period

Date: May 2010
Creator: Sheppard, Rebecca Replogle
Description: The purpose of this study was to determine the effects of salary, compensation and benefits, accountability, job stress, increased instructional responsibilities, changes in student demographics, lack of support, politics, advancement opportunities and promotion on tenure and turnover among high school principals in the state of Texas. The participants in the study included 60 Texas high school principals who left a high school principalship for a different high school principalship within the past 5 years. The participants completed the Texas Principal Survey and data were analyzed using binary logistic regression. The data indicated that salary, compensation and benefits was a significant factor in predicting an increase in the odds of principal turnover for principals who had been in their prior principalship 5 or more years over principals who had been in their prior principalship less than 5 years. Additionally, advancement opportunities was a significant factor in predicting a decrease in the odds of principal turnover for principals who had been in their prior principalship 5 or more years over principals who had been in their prior principalship less than 5 years. Responses from an open ended question asking principals why they left their prior principalship suggested that principals left for reasons ...

Discovery of Resources and Conflict in the Interstate System, 1816-2001

Discovery of Resources and Conflict in the Interstate System, 1816-2001

Date: May 2010
Creator: Clark, Bradley
Description: This study tests a theory detailing the increased likelihood of conflict following an initial resource discovery in the discovering nation and its region. A survey of prior literature shows a multitude of prior research concerning resources and nations' willingness to initiate conflict over those resources, but this prior research lacks any study concerning the effects of the discovery of resources on interstate conflict. The theory discusses the increased likelihood of conflict in the discovering nation as both target and initiator. It further looks at the increased chance of conflict in the discoverer's region due to security dilemmas and proxy wars. The results show strong support for the theory, suggesting nations making new resource discoveries must take extra care to avoid conflict.

Does the Provision of an Intensive and Highly Focused Indirect Corrective Feedback Lead to Accuracy?

Does the Provision of an Intensive and Highly Focused Indirect Corrective Feedback Lead to Accuracy?

Date: May 2010
Creator: Jhowry, Kheerani
Description: This thesis imparts the outcomes of a seven-week long quasi-experimental study that explored whether or not L2 learners who received intensive and highly focused indirect feedback on one type of treatable error - either the third person singular -s, plural endings -s, or definite article the - eventually become more accurate in the post-test as compared to a control group that did not. The paired-samples t-test comparing the pre-test and post-test scores of both groups demonstrates that the experimental group did no better than the control group after they received indirect corrective feedback. The independent samples t-test measuring the experimental and control group's accuracy shows no significant difference between the two groups. Effect sizes calculated, however, do indicate that, had the sample sizes been bigger, both groups would have eventually become more accurate in the errors targeted, although this would not have been because of the indirect feedback.

Easter Seals North Texas Autism Treatment Program Evaluation: Child Progress

Easter Seals North Texas Autism Treatment Program Evaluation: Child Progress

Date: May 2010
Creator: Brunson, Lashanna Yvette
Description: This study reports and evaluates child outcome measures at a non-profit autism treatment program providing applied behavior analysis (ABA) based services to children age 3 to 8. To accomplish this, a review was conducted of available outcome data for a 1 year period. Several categories of outcome measures have been reported in the autism treatment literature (post-intervention educational placement, cognitive status, developmental and achievement status and/or progress, autism symptom reduction, and diagnostic reclassification). This study found that the program relied on 2 sources of data to evaluate child outcome: Hawaii Early Learning Profile® and program goal mastery. Children are making progress as indicated by these measures. The findings are discussed in relation to broader outcome recommendations.

EEG, Alpha Waves and Coherence

EEG, Alpha Waves and Coherence

Date: May 2010
Creator: Ascolani, Gianluca
Description: This thesis addresses some theoretical issues generated by the results of recent analysis of EEG time series proving the brain dynamics are driven by abrupt changes making them depart from the ordinary Poisson condition. These changes are renewal, unpredictable and non-ergodic. We refer to them as crucial events. How is it possible that this form of randomness be compatible with the generation of waves, for instance alpha waves, whose observation seems to suggest the opposite view the brain is characterized by surprisingly extended coherence? To shed light into this apparently irretrievable contradiction we propose a model based on a generalized form of Langevin equation under the influence of a periodic stimulus. We assume that there exist two different forms of time, a subjective form compatible with Poisson statistical physical and an objective form that is accessible to experimental observation. The transition from the former to the latter form is determined by the brain dynamics interpreted as emerging from the cooperative interaction among many units that, in the absence of cooperation would generate Poisson fluctuations. We call natural time the brain internal time and we make the assumption that in the natural time representation the time evolution of the EEG variable ...

Effect of Fluorine and Hydrogen Radical Species on Modified Oxidized Ni(pt)si

Effect of Fluorine and Hydrogen Radical Species on Modified Oxidized Ni(pt)si

Date: May 2010
Creator: Gaddam, Sneha Sen
Description: NiSi is an attractive material in the production of CMOS devices. The problem with the utilization of NiSi, is that there is no proper method of cleaning the oxide on the surface. Sputtering is the most common method used for the cleaning, but it has its own complications. Dry cleaning methods include the reactions with radicals and these processes are not well understood and are the focus of the project. Dissociated NF3 and NH3 were used as an alternative and XPS is the technique to analyze the reactions of atomic fluorine and nitrogen with the oxide on the surface. A thermal cracker was used to dissociate the NF3 and NH3 into NFx+F and NHx+H. There was a formation of a NiF2 layer on top of the oxide and there was no evidence of nitrogen on the surface indicating that the fluorine and hydrogen are the reacting species. XPS spectra, however, indicate that the substrate SiO2 layer is not removed by the dissociated NF3 and NiF2 growth process. The NiF2 over layer can be reduced to metallic Ni by reacting with dissociated NH3 at room temperature. The atomic hydrogen from dissociated ammonia reduces the NiF2 but it was determined that the ...

The Effects of Jackpots on Responding and Choice in Two Domestic Dogs

The Effects of Jackpots on Responding and Choice in Two Domestic Dogs

Date: May 2010
Creator: Muir, Kristy Lynn
Description: The current study investigated the impact of delivering a jackpot on response rate and response allocation in two domestic dogs. For the purpose of this research, a jackpot was defined as a one-time, within-session increase in the magnitude of reinforcement. Two experiments were conducted to investigate the effects of delivering a jackpot in both single-operant and concurrent schedule procedures. Experiment 1 investigated the impact of a one-time, within-session increase in the magnitude of reinforcement on response rate in a single-operant procedure. Results of Experiment 1 showed no clear change in response rate after the delivery of the jackpot. Experiment 2 investigated the impact of a one-time, within-session increase in the magnitude of reinforcement on response allocation in a concurrent schedule procedure. Results of Experiment 2 showed an increase in response allocation to the jackpotted contingency in both subjects. These results suggest that a jackpot, as defined here, has no effect in single-operant procedures while having an effect in concurrent schedule procedures. These effects are similar to those reported in the magnitude of reinforcement literature.

Effects of Rebar Temperature and Water to Cement Ratio on Rebar-Concrete Bond Strength of Concrete Containing Fly Ash

Effects of Rebar Temperature and Water to Cement Ratio on Rebar-Concrete Bond Strength of Concrete Containing Fly Ash

Date: May 2010
Creator: Pati, Ardeep Ranjan
Description: This research presents the results on an experimental investigation to identify the effects of rebar temperature, fly ash and water to cement ratio on concrete porosity in continuously reinforced concrete pavements (CRCP). Samples were cast and analyzed using pullout tests. Water to cement ratio (w/c) and rebar temperature had a significant influence on the rebar-concrete bond strength. The 28-day shear strength measurements showed an increase in rebar-concrete bond strength as the water to cement ratio (w/c) was reduced from 0.50 to 0.40 for both fly ash containing and non fly ash control samples. There was a reduction in the peak pullout load as the rebar surface temperature increased from 77o F to 150o F for the cast samples. A heated rebar experiment was performed simulating a rebar exposed to hot summer days and the rebar cooling curves were plotted for the rebar temperatures of 180o F - 120o F. Fourier transform infrared spectroscopy was performed to show the moisture content of cement samples at the rebar-concrete interface. Mercury intrusion porosimetry test results on one batch of samples were used for pore size distribution analysis. An in-depth analysis of the morphological characteristics of the rebar-concrete interface and the observation of pores ...

Effects of Suspended Multi-Walled Carbon Nanotubes on Daphnid Growth and Reproduction

Effects of Suspended Multi-Walled Carbon Nanotubes on Daphnid Growth and Reproduction

Date: May 2010
Creator: Alloy, Matthew Michael
Description: Multi-walled carbon nanotube aggregates can be suspended in the aqueous phase by natural organic matter. These aggregates are ingested by filter feeding zooplankton. Ingested aggregates result in decreased growth and decreased reproduction. These effects may be caused by reduction in energy input from normal feeding behavior. pH alters natural organic matter structure through changes in electrostatic repulsion. Altered natural organic matter structure changes multi-walled carbon nanotube aggregate size. This size variation with variation in pH is significant, but not large enough a change in size to alter toxicity, as the aggregate size range remains well within the particle size selection of the organisms.

Effects of Tasks on Information-Seeking Behavior in a Police Work Environment in the Context of Criminal Intelligence

Effects of Tasks on Information-Seeking Behavior in a Police Work Environment in the Context of Criminal Intelligence

Date: May 2010
Creator: Tatil, Serkan
Description: Although dominant effects of tasks on individuals' information-seeking behavior is accepted by many scholars, a limited number of studies has been conducted to reveal the nature of the relationship between tasks and information-seeking behavior. In their studies, some earlier researchers categorized tasks according to their complexity while others did the same according to the specifications of tasks. Two of the groundbreaking researchers in this area are Katriina Byström and Kalervo Järvelin who contributed to the understanding of the relationship between task complexity and information-seeking behavior. However, their findings also need empirical support for theory growth. In response to this need, this study attempts to test Byström and Järvelin's findings through a research using different research methods and applied in a police work environment. Other than providing empirical support for theory growth, this research is also expected to contribute to the understudied area of police information-seeking behavior. Both qualitative and quantitative data were collected from the participants who came from traffic, homicide, and anti-terrorism divisions of Ankara, Eskisehir, and Kirikkale Police Departments in Turkey. The participants identified terrorism cases as the most complex cases to solve, followed by homicide and traffic accident cases. Differences in the information-seeking behavior of three groups ...

Creator: Darweesh, Ali Hussain
Description: The purpose of this study was twofold: (1) to examine the knowledge, skills, and experiences in the enameling arts and the attitudes and perceptions of in-service (n = 12) and pre-service Kuwaiti art teachers (n = 170), art supervisors at the Ministry of Education (MOE) (n = 3) and art education faculty members at the College of Basic Education (CBE) and Kuwait University (KU) (n = 8) about what they believed pre-service art teachers should know and be able to do in order to teach the enameling arts, and (2) to use this information to inform and guide the development of a content outline for an enameling course for pre-service Kuwaiti art teachers that is educationally (how to perform enameling arts skills and how to teach what they know), practically (safety issues, workshop management, etc), and culturally (its relation to Islamic culture) suitable. Both quantitative and qualitative approaches were used. Most of the respondents revealed limited knowledge and skills and modest experiences in the enameling arts. All interviewees in the study expressed positive perceptions and attitudes about the enameling arts. Most agreed that a revision to the current art education curriculum at the CBE was needed and made suggestions about ...

Evaluating the Effectiveness of a Comprehensive Staff Training Package for Behavioral Interventions for Children with Autism

Date: May 2010
Creator: Weinkauf, Sara Marie
Description: The effectiveness of behavioral interventions for the treatment of young children with autism has been well documented in professional literature. The success of these procedures, however, depends on the fidelity of implementation and proper training of the therapist. The purpose of this study was to evaluate a 125-skill, comprehensive staff training package that involved a graduated sequence of teaching. In addition to changes in skills, social validity and training time were also assessed. Results indicate that correct demonstration of skills increased following training, incorrect implementation decreased, teachers rated the procedures favorably, and the total training took between 20 and 32.5 hours for over 120 skills to reach mastery criteria. A discussion of the results as well as implications for future research is also provided.

Examining the Origins of Sociology: Continuities and Divergences Between Ibn Khaldun, Giambattista Vico, August Comte, Ludwig Gumplowicz, and Emile Durkheim

Date: May 2010
Creator: Soyer, Mehmet
Description: This thesis examines the extent to which Ibn Khaldun can legitimately be considered a founding father of sociology. To pursue this research, Khaldun's theoretical framework will be compared with four Western scholars: Auguste Comte, Emile Durkheim, Giambattista Vico, and Ludwig Gumplowicz. This paper begins with an Introduction (Chapter I), followed by a general overview of Khaldun's work (Chapter II). Next, Khaldun's work is compared to that of Auguste Comte (Chapter III), Emile Durkheim (Chapter IV), Ludwig Gumplowicz (Chapter V) and Giambattista Vico (Chapter VI). In each of these chapters, Khaldun is compared and contrasted to the other social theorist, illustrating their similarities and considering their differences. Finally, in Chapter VII, I put forth conclusions that consider the extent to which Khaldun can validly be considered a founding father of sociology.

An Experimental Study on Situated and Dynamic Learning Assessment (SDLA) Environment

An Experimental Study on Situated and Dynamic Learning Assessment (SDLA) Environment

Date: May 2010
Creator: Lee, Zeng-Han
Description: The current supplementary web based English learning in Taiwan provides online learning resources and gives assessments at the end of each lesson to evaluate learners' online learning results. Based on the testing results, instructors may adjust their in-class instructional method to focus on the students' weaknesses. For the average classroom size of 40 students with one instructor, it is extremely difficult to provide individual learning content for each learner's needs because each student has his or her own weaknesses. This study conducted the situated environment with Vygotsky's dynamic assessment theory to test learner's learning achievements and satisfactions as compared to the current web learning environment. The study finds that when both groups of Taiwanese students used Internet based learning, those that utilized the situated and dynamic learning assessment environment showed a statistically significant higher achievement score than those using only the current online learning environment (p < .01). In addition, learners in the SDLA environment had statistically significant higher satisfaction scores than those in the current web learning environment.

Creator: Sweeney, Mark
Description: Investigating elements of the creative process in the work of three poets: James Wright, Gjertrud Schnackenberg, and Pegeen Kelly. Each poet deploys a different method for access to those experiences that lie at the edge of accessible language. Each method is discussed and its deployment illustrated. Wright leads us from the sensory world to the supersensual. Schnackenberg makes use of the formal device of the fairy tale. Kelly immerses in the logic of dreams. Drawing on Elaine Scarry's theory of the imagination, the case is made that the poetic act is a dialectic between the poet and the sensory world, in which perception and imagination are equally important.

Geographic Distance, Contact, and Family Perceptions of Quality Nursing Home Care

Geographic Distance, Contact, and Family Perceptions of Quality Nursing Home Care

Date: May 2010
Creator: Dillman, Jennifer L
Description: The effect of frequency of nursing home contact on family perceptions of quality care is the focus of this research. A family member characteristic, such as geographic distance from the nursing home, affects his or her frequency of contact with the nursing home. Frequency of contact, in turn, affects family perceptions of the care his or her loved one receives in the nursing home. The theoretical framework for this study is based on Allport's intergroup contact theory, which posits that when four contact conditions - institutional support, equal status, common goals, and intergroup cooperation - are present in an intergroup situation, a reduction in anxiety between groups is likely to occur. Regression analysis tested the stated hypotheses using survey data collected from 275 family members of residents in 10 Dallas-Ft. Worth area nursing homes. This study is among the first to quantify family geographic distance, finding that family geographic distance is a significant negative predictor of nursing home contact. Additionally, results build on Allport's theory by extending its' usefulness to nursing home organizations in two distinct ways. First, findings support Allport's premise that contact alone between groups - i.e., family members and nursing home staff - is insufficient for increasing ...
