Alternative Information Processing Formats for Overcoming Information Processing Deficits in Senior Adults

Access: Use of this item is restricted to the UNT Community
The objective of this study was to examine the effectiveness of alternative advertising presentation formats, and the quantity of information presented in advertisements in overcoming possible information-processing deficits in senior adults that could affect their recall of ad attributes and brand name, the cognitive responses generated, and attitude toward the ad. In addition, the study examined the effectiveness of retirement status as a classification or segmentation variable in comparison with the use of the more traditional classification variable, chronological age. A convenience sample of senior adult volunteers from church groups, social clubs, and civic organizations from the local area were randomly assigned to one of nine experimental conditions. The experiment utilized a simulated magazine to test the effects of presentation formats (3 levels), and quantity of information (3 levels) on senior adult's recall, cognitive responses and attitude toward the test ads. Covariates (gender, wealth, education, activity level, health, and income) were used to reduce variance. The findings clearly indicate that the presentation format of the can ad adversely affected the memory of some senior adults. In addition, the results were significantly different across the different age levels. Retirement status was less beneficial than chronological age in the current study, but …

The Apologist Tradition: A Transitional Period in Southern Proslavery Thought, 1831-1845

Access: Use of this item is restricted to the UNT Community
Early antebellum defenders of slavery acknowledged that slavery created problems for southern society. They contended, however, that slave society was better and more natural than other forms of social organization. Thomas R. Dew, William Harper, and James Henry Hammond each expressed a social philosophy in which slavery had a crucial role in preserving social order. They argued from the basis of social organicism, the idea that society should have an elite that controlled the masses. For all three men, slavery represented a system of order that helped balance the dangers of democracy. Significantly, however, all three men recognized that the slave system was not perfect, and despite their defense of slavery, argued that it was a human institution and therefore corruptible.

Bird Bones and a Hatched Egg

Access: Use of this item is restricted to the UNT Community
A fifty page manuscript of poetry and a critical introduction detailing the poet's aesthetics. Using the idea of the double-image and eroticism, the poet places her work in the category of the surreal. She describes the process of writing poetry born of fragmentary elements as a feminist emergence of agency. The manuscript is composed of four sections, each an element in the inevitable breakdown of a love relationship: meeting, love-making, birth of a child, death. Quotes from various authors of anthropological and fictional texts begin each section to reinforce thematic structure in a process of unveiling the agency of the narrator. The poems are organized as a series, beginning and ending with sequence poems.

Diphosphine Ligand Activation Studies with Organotransition-Metal Compounds

Access: Use of this item is restricted to the UNT Community
Thermolysis of CoRu(CO)7(m -PPh2) (1) in refluxing 1,2-dichloroethane in the presence of the diphosphine ligands 2,3-bis(diphenylphosphino)maleic anhydride (bma) and 4,5-bis(diphenylphosphino)-4-cyclopenten-1,3-dione (bpcd) furnishes the new mixed-metal complexes CoRu(CO)4(μ -P-P)(μ -PPh2) [where P-P = bma (3); bpcd (6)], along with trace amounts of the known complex CoRu(CO)6(PPh3)(μ -PPh2) (4). The requisite pentacarbonyl intermediates CoRu(CO)5(μ -P-P)(μ -PPh2) [where P-P = bma (2); bpcd (5)] have been prepared by separate routes and studied for their conversion to CoRu(CO)4(μ -P-P)(μ -PPh2). The complexes 2/3 and 5/6 have been isolated and fully characterized in solution by IR and NMR spectroscopy. The kinetics for the conversion of 2→3 and of 5→6 were measured by IR spectroscopy in chlorobenzene solvent. On the basis of the first-order rate constants, CO inhibition, and the activation parameters, a mechanism involving dissociative CO loss as the rate-limiting step is proposed. The solid-state structure of CoRu(CO)4(μ -bma)(μ -PPh2) (3) reveals that the two PPh2 groups are bound to the ruthenium center while the maleic anhydride π bond is coordinated to the cobalt atom. Thermolysis of the cluster Ru3(CO)12 with the bis(phosphine)hydrazine ligand (MeO)2PN(Me)N(Me)P(OMe)2 (dmpdmh) in toluene at 75°C furnishes the known clusters Ru4(CO)12[μ -N(Me)N(Me)] (9) and Ru3(CO)11[P(OMe)3] (10), in addition to the new …

The Effect of Attachment on Preschooler's Emotion Understanding

Access: Use of this item is restricted to the UNT Community
The purpose of this study was to identify the relationship between attachment and emotion understanding in preschoolers. Data was collected from 16 preschool children and their mothers recruited from a private learning center in a downtown metropolitan area. Attachment was measured by use of the Attachment Q-sort, 3.0 (Waters, 1995), while emotion understanding was assessed through use of Denham's (1986) affective perspective-taking task and interviews of children concerning naturally occurring emotions and emotion causes (Fabes et al., 1991). Results included a significant correlation (p < .05) between secure attachment and preschooler's ability to decipher the cause of another's emotion; however, a significant correlation was not found between secure attachment and preschooler's perspective-taking ability or ability to name other's emotions. Thus, conclusions about the impact of attachment upon emotion understanding were mixed, and more research on the subject was implicated.

Effect of Engineered Surfaces on Valve Performance

Access: Use of this item is restricted to the UNT Community
Performance of air operated valves is a major maintenance concern in process industries. Anecdotal information indicates that reliability of some high maintenance valves has been improved by using an ion deposition process to achieve engineered surfaces on selected components. This project compared friction for various surface treatments of selected valve components. Results indicate valve performance may be slightly more consistent when an engineered surface is applied in the valve packing area; however surface treatment in this area does not appear to have a dominant affect on reducing valve friction. Results indicate a linear relation between stem friction and torque applied to packing flange nuts, and even after a valve is in service, controlled packing adjustments can be made without significantly changing valve stroke time.

Effects of Reinforcement History on Stimulus Control Relations

Access: Use of this item is restricted to the UNT Community
Ray (1969) conducted an experiment on multiple stimulus-response relations and selective attention. Ray's (1969) results suggested that stimulus-response relations function as behavioral units. McIlvane and Dube (1996) indicated that if stimulus-response relations are behavioral units the effects of environmental variables on stimulus-response relations should be similar to the effects of environmental variables on single response topographies. This experiment analyzed the effects of reinforcement history on the probability of stimulus-response relations with differing reinforcement histories. In separate conditions random-ratio schedules of reinforcement were contingent on each of four discriminated responses. To assess the effects of reinforcement, during test conditions stimuli controlling different topographies were present concurrently in composite form. Results show that reinforcement history affects the probability of each response topography and that the association between response topographies and their controlling stimuli tends to remain constant throughout variations in reinforcement probability.

Factors Affecting Household Disaster Preparedness: A Study of the Canadian Context

Access: Use of this item is restricted to the UNT Community
This study addresses the issue of household disaster preparedness. This work contributes two elements to disaster research. The first contribution improve the knowledge of the factors that affect household disaster preparedness. The review of literature yielded three categories of variables that can jointly explain household disaster preparedness: household structure, demographics, and risk-perception factors. In this study 19 variables compose these factors. A second contribution constitutes a theoretical exploration of the concept of disaster preparedness. In this work, four different constructs of disaster preparedness were tested. These constructs include material preparedness, preparedness activities, a combined index, and a weighted and combined index. The study presents the logic and methodology of the index construction and validation. The data used in this study came from households in the Montreal Urban Community (MUC) in Canada. A random sample of 1,003 English- and French-speaking heads of households adequately represents the 1.8 million persons within the MUC. An independent survey firm conducted the interviews in 1996. Results show that the weighted combined household disaster preparedness index constitutes the best construct to represent the concepts under study. Study results also reveal that risk-perception variables (attitudinal factors) offered the strongest explanatory power. Household structure and demographic variables collectively …

Juvenile Justice Sentencing: Are There Alternatives?

Access: Use of this item is restricted to the UNT Community
Research indicates that states have implemented juvenile justice reforms to enact harsher punishments, to transfer greater numbers and younger juvenile offenders to adult criminal court, and to restrict discretion of the juvenile court judges. Social science studies have found that harsher punishments, transfers to adult criminal court and other measures do not work, but that comprehensive approaches which address the numerous major factors contributing to juvenile offending have been successful. This study examined the legal status of the juvenile justice system by focusing upon ten diverse sample states and analyzed the social science research on factors contributing to juvenile offending and on prevention, treatment, and rehabilitation approaches. The study was accomplished by legal research, qualitative social science research, and analysis of both. Findings indicated: a) state statutes require and allow adult punishment of juvenile offenders, transfer of juvenile offenders to adult criminal court, and direct filing of charges against juveniles in adult criminal court; most states begin these proceedings at age 14, some have no age minimum; b) social science research indicates numerous factors contribute to juvenile offending with most of the factors categorized into the major factors of early antisocial behavior, deviant peers, parents and family, sociomoral reasoning, biological …

Logic Programming Tools for Dynamic Content Generation and Internet Data Mining

Access: Use of this item is restricted to the UNT Community
The phenomenal growth of Information Technology requires us to elicit, store and maintain huge volumes of data. Analyzing this data for various purposes is becoming increasingly important. Data mining consists of applying data analysis and discovery algorithms that under acceptable computational efficiency limitations, produce a particular enumeration of patterns over the data. We present two techniques based on using Logic programming tools for data mining. Data mining analyzes data by extracting patterns which describe its structure and discovers co-relations in the form of rules. We distinguish analysis methods as visual and non-visual and present one application of each. We explain that our focus on the field of Logic Programming makes some of the very complex tasks related to Web based data mining and dynamic content generation, simple and easy to implement in a uniform framework.

Sarah T. Hughes: Her Influence in Texas Politics

Access: Use of this item is restricted to the UNT Community
Conservative males traditionally dominated Texas politics. In 1930, however, Sarah T. Hughes, a liberal woman from Maryland, began a spectacular career in state politics despite obstacles because of her gender and progressive ideas. First elected to the Texas Legislature in 1930, she remained active in politics for the next fifty years. Hard work, intelligence, and ability allowed her to form solid friendships with Texas's most powerful politicians. She became the first woman in Texas to hold a district judgeship, the first woman from Texas appointed to the federal bench, and the only woman to swear in a U.S. president. Hughes profoundly influenced state politics, challenging the long-standing conservative male domination. She helped to create a more diverse political field that today encompasses different ideologies and both genders.

Work in the calling in Max Weber's Protestant ethic thesis

Access: Use of this item is restricted to the UNT Community
Objectives. Scholars have debated Max Weber's theory of the relationship between religion and capitalism for almost 100 years. Still, the debate is clouded by confusion over Weber's claims about religious doctrine and over the supporting evidence. The purpose of this study is to clarify Max Weber's claims regarding the concept of the calling and the related "anti-mammon" injunction and concept of "good works" and substantiate with historical evidence the religious doctrine Weber describes. Methods. Comparative analysis of early Protestant Lutheran and Calvinist documents from the sixteenth and seventeenth centuries was used to flesh out a history of ideas to determine whether evidence exists to support Weber's claims related to religious doctrine. Results. Historical analyses revealed that the concept of the calling pre-dated Luther in the Bible. Luther's innovation was not in his use of the word beruf but in his application of the concept of the calling to the common people and his teaching of that idea. The idea of sanctified work was key in both Lutheran and Calvinist documents. There was an increased emphasis on work and encouragement to accumulate wealth in Calvinist documents. Conclusion. Weber's etymological evidence surrounding Martin Luther's use of the word beruf in his German …

Analysis of the Impact of CACREP Accreditation of Counselor Education Programs on Student Knowledge Outcomes

Access: Use of this item is restricted to the UNT Community
The principal investigator (PI) for this study analyzed mean scores on the National Counselor Examination (NCE) of students from CACREP accredited and non- CACREP accredited programs. Data was provided by the National Board of Certified Counselors, Inc., for a total of ten examination administrations across six years. The fourteen variables examined in the study consisted of the eight common-core knowledge domains identified in CACREP standards, the five counselor work behavior areas identified by NBCC via periodic job analysis of counseling practice, and one overall or total score on the NCE. NCE mean scores of students from CACREP accredited programs were higher than NCE mean scores of students from non-CACREP accredited programs on all variables across all ten NCE administrations. Data seem to indicate that students from CACREP accredited programs perform significantly better on the NCE than students from non-CACREP accredited programs, in all fourteen variables. Sample size was large, totaling 9707, so the PI calculated effect sizes using Cohen's d for each variable to aid interpretation of statistical significance. Five variables had large effect sizes of .70 or higher. The higher effect size statistics were associated with the counselor work behavior areas, with the highest effect size (.85) associated with …

Animal Contribution to Human Medicine

Access: Use of this item is restricted to the UNT Community
The use of animal models in research has led to a fierce debate between animal rights activists and scientists. The former claim that little useful information is gained from animal studies and the suffering of animals does not preclude any treatments which may be used to treat human illnesses. Yet, research scientists claim that in vivo animal models are of absolute necessity to developing treatments and cures to disease. To determine the necessity of animal use, one must examine the models currently in research. Have the animal models for disorders such as cystic fibrosis and muscular dystrophy given scientists enough information to develop effective treatments? This paper will examine the role of animal subjects in several disease research protocols, as well as the applicability of the research.

The Break-up of the Confederate Trans-Mississippi Army, 1865

Access: Use of this item is restricted to the UNT Community
Unlike other Confederate armies at the conclusion of the Civil War, General Edmund Kirby Smith's Trans-Mississippi Army disbanded, often without orders, rather than surrender formally. Despite entreaties from military and civilian leaders to fight on, for Confederate soldiers west of the Mississippi River, the surrender of armies led by Generals Robert E. Lee and Joseph E. Johnston ended the war. After a significant decline in morale and discipline throughout the spring of 1865, soldiers of the Confederate Trans-Mississippi Department chose to break-up and return home. As compensation for months of unpaid service, soldiers seized both public and private property. Civilians joined the soldiers to create disorder that swept many Texas communities until the arrival of Federal troops in late June.

Development of a Procedure to Evaluate Groundwater Quality and Potential Sources of Contamination in the East Texas Basin

Access: Use of this item is restricted to the UNT Community
This study contributes a procedure, based on data analysis and geostatistical methods, to evaluate the distribution of chemical ratios and differentiate natural and anthropogenic contaminant sources of groundwater quality in the East Texas Basin. Four aquifers were studied, Sparta, Queen City, Carrizo and Wilcox. In this study, Carrizo- Wilcox is considered as one aquifer, and Sparta-Queen City as another. These aquifers were divided into depth categories, 0-150 feet for Sparta-Queen City and 300-600 feet and 600-900 feet for Carrizo-Wilcox in order to identify individual sources of contamination. Natural sources include aquifer mineral make up, salt domes and lignite beds. Major anthropogenic sources include lignite and salt dome mining and oil-gas production. Chemical ratios selected were Na/Cl, Ca/Cl, Mg/Cl, SO4/Cl, (Na+Cl)/TDS, SO4/Ca and (Ca+Mg)/(Na+K). Ratio distributions and their relationships were examined to evaluate physical-chemical processes occurring in the study area. Potential contaminant sources were used to divide the Basin into three areas: Area 1 to the east, Area 2 in the west and Area 3 in the center. Bivariate analysis was used to uncover differences between the areas. The waters in Area 1 are potentially impacted primarily from oil field waters. Sources present in Area 2 include lignite beds and oil …

Distribution and Probable Sources of Nitrate in the Seymour Aquifer, North Central Texas, USA

Access: Use of this item is restricted to the UNT Community
This study utilized GIS and statistical methods to map the spatial variability of nitrate and related groundwater constituents in 30 counties above the Seymour Aquifer, analyze temporal patterns of nitrate pollution, identify probable sources of pollution, and recommend water development strategies to minimize exposure to nitrate and reduce future aquifer contamination. Nitrate concentrations in excess of 44 mg/L (US EPA limit) were commonly observed in the Seymour Aquifer region, especially in the central agricultural belt. Data indicated that this is an ongoing problem in the Seymour Aquifer and that agricultural activity and rural septic systems are the likely sources of the nitrate. Inconclusive results emphasized the need for a more comprehensive spatial and temporal water quality monitoring.

The Effect of Faculty Development on Active Learning in the College Classroom

Access: Use of this item is restricted to the UNT Community
This study examined the effect of active learning seminars and a mentoring program on the use of active learning teaching techniques by college faculty. A quasi-experimental study was conducted using convenience samples of faculty from two private Christian supported institutions. Data for the study were collected from surveys and faculty course evaluations. The study lasted one semester. Faculty volunteers from one institution served as the experimental group and faculty volunteers from the second institution were the comparison group. The experimental group attended approximately eight hours of active learning seminars and also participated in a one-semester mentoring program designed to assist faculty in application of active learning techniques. Several individuals conducted the active learning seminars. Dr. Charles Bonwell, a noted authority on active learning, conducted the first three-hour seminar. Seven faculty who had successfully used active learning in their classrooms were selected to conduct the remaining seminars. The faculty-mentoring program was supervised by the researcher and conducted by department chairs. Data were collected from three surveys and faculty course evaluations. The three surveys were the Faculty Active Learning Survey created by the researcher, the Teaching Goals Inventory created by Angelo and Cross, and the college edition of Learner-Centered Practices by Barbara …

The Effect of Steroid Dose Regimen on the Relationship Between Lower Extremity Muscle Function and Cardiac Function in Post Heart Transplant Patients

Access: Use of this item is restricted to the UNT Community
Differences in cardiovascular/aerobic function in heart transplant patients might be attributed to the rate of corticosteroid withdrawal and/or to skeletal muscle function. This hypothesis was tested among nine male, cardiac transplant recipients. Prednisone dosage was monitored, and isokinetic strength testing was performed at 4 different time periods throughout the first year post-transplantation. Cardiovascular/aerobic measurements were obtained at the fourth time period. Pre-surgery characteristics were obtained from the patient's medical record. Significant Pearson-product moment correlations were only found between muscle function and aerobic function and between pre-surgery characteristics and cardiovascular/aerobic performance. The results of this study show no evidence that rapid reduction of prednisone dosage enhances aerobic function by benefiting skeletal muscle function.

Effectiveness of Filial/Play Therapy Training on High School Students' Empathic Behavior with Young Children

Access: Use of this item is restricted to the UNT Community
This study was designed to determine the effectiveness of a filial/play therapy training model with high school juniors and seniors enrolled in a Peer Assistance and Leadership program (PALs). Filial/play therapy is an intervention that focuses on strengthening and enhancing adult-child relationships. The high students are trained to be a therapeutic change agent for primary school children identified as having adjustment difficulties by utilizing basic child-centered play therapy skills in weekly play sessions with young children. Specifically, this study is designed to determine the effectiveness of filial therapy in increasing: 1) the high school students' observed empathic behavior with young children, 2) the high school students' observed attitude of acceptance toward young children, 3) the high school students' observed ability to allow self-direction in young children, and 4) the high school students' observed level of involvement with young children. The experimental group, consisting of 16 volunteer high school students enrolled in a PALs class for high school credit, received a total of 24 weeks of filial/play therapy didactic training, application, and supervision for the playtimes they conducted with pre-kindergarten/kindergarten students identified with adjustment difficulties.

The Effects of a Conflicting Instruction on a Fr 5 Performance

Access: Use of this item is restricted to the UNT Community
The purpose of this experiment was to evaluate the effects of a conflicting instruction on FR-5 performances by an ABABC design. After all four college students were consistently pressing 1-5-3 followed by sound-clips, the schedule value changed to FR-5 (A). Then they were presented with the written instruction "Press 426" (B) in addition to the previous condition. In the last condition (C), 1-5-3 responses were then scheduled for extinction in three participants and the reinforcer was changed from sound-clips to points for one participant. The results showed that unlike previous experiments, instructions did not override the scheduled contingencies. Instruction-following occurred only when there were no other contingencies (i.e., extinction of 1-5-3) or the scheduled reinforcer for FR-5 performances was weak.
