Modification of Cardiac Membrane Gsα by an Endogenous Arginine-Specific Mono-Adp-Ribosyltransferase
The mechanism by which nicotinamide adenine dinucleotide (NAD) stimulates the activity of adenylate cyclase (AC) in canine plasma membrane has been studied. Using [3 2P]-NAD, the activation by NAD was correlated with the radiolabeling of the stimulatory guanosine triphosphate (GTP) binding protein Gsa. Further characterization demonstrated that the modification occurred only in the presence of G-protein activators and that arginine residue(s) were modified by ADP-ribose by the action of a mono-ADP-ribosyltransferase. Inhibitors of the transferase blocked both the modification of Gsa and the activation of AC. Collectively, these studies suggest that ADP-ribosylation of Gsa by an endogenous mono-ADP-ribosyltransferase may regulate cardiac AC.

The Influence of Pragmatism in the Essays of Randolph Bourne
This study traces the influence of the American philosophy of pragmatism in the writing of the Progressive Era intellectual Randolph Bourne (1886-1918),. In courses with John Dewey at Columbia University and through the books of William James, pragmatism became a major intellectual factor in Bourne's social and cultural criticism. The philosophy remained so to the end of his brief career. From pragmatism, Bourne learned a method of challenging a restrictive status quo. In his essays, Bourne sought harmony between analytical reasoning and the imagination in order to promote self-growth along with the creation of a more humane society. Bourne promoted individualism and the need for transcendent values in modern industrial society.

The Crucifixion
The Crucifixion, a composition for three vocal soloists, four-part mixed chorus, and instrumental ensemble, is a setting of passages taken from the four Gospels of the Holy Bible. It describes the mocking of Christ and includes the Seven Last Words of Christ on the cross. It uses serial technique in the structuring of pitches and rhythm. Special attention is paid in designing and combining pitch and rhythm to create monophonic, homophonic and polyphonic textures. Besides traditional performance techniques, the work employs some modern vocal and instrumental techniques.

Bolshevik Britain: An Examination of British Labor Unrest in the Wake of the Russian Revolution, 1919
The conclusion of the First World War brought the resumption of a struggle of a different sort: a battle between government and labor. Throughout 1919, government and labor squared off in a struggle over hours, wages, and nationalization. The Russian Revolution introduced the danger of the bolshevik contagion into the struggle. The first to enter into this conflict with the government were the shop stewards of Belfast and Glasgow. The struggle continued with the continued threats of the Triple Alliance and the police to destroy the power of the government through industrial action. This thesis examines the British labor movement during this revolutionary year in Europe, as well as the government's response to this new danger.

The Effects of Parental Substance Abuse on the Behavior of School Children
The purpose of the present archival study was to investigate the relationship between parental substance abuse and the risk for maladjustment and psychopathology in children in a clinic sample. Children of alcoholic parents and children of drug-dependent parents were compared to children of non-substance abusing parents. The subjects were 83 boys age 6 to 12. Children of substance abuse parents had lower levels of adaptive functioning and higher levels of school behavioral problems. Although previous studies have reported a strong association between an adverse family environment and the risk of child maladjustment, the present study did not find that the addition of an adverse family environment increased the risk for maladjustment or school behavioral problems in children of substance abusers.

Effects of Positive Verbal Reinforcement on the Four Underlying Factors in Intrinsic Motivation
The study examined the effects of positive verbal reinforcement on intrinsic motivation by determining differential effects over four multidimensions of Ryan's Intrinsic Motivation Inventory (IMI). Subjects (N=60) were 30 male and 30 female college students. The subjects were blocked by gender and randomly assigned to a positive verbal reinforcement group or a control group. The subjects received 10 trials on the stabilometer. The results of the study indicated that there were significant group differences for composite intrinsic motivation and for perceived competence; however, there were no significant gender differences found. Furthermore, no group differences were reported for the underlying factors of interest/enjoyment, effort, or pressure/tension.

Evaluation of Transfer of Technical Training: A Prototype
The degree of transfer of technical training to workplace behavior was evaluated using a Solomon Four-Group experimental design. Additionally, all groups received retrospective pretests. Subjects were 103 technicians in an electronics company. Supervisors rated technicians on behaviorally anchored rating scales which were developed and labeled as behavior description scales for simplicity. Analysis of variance revealed no effect for training nor pretest. A training-pretest interaction effect was revealed for one dimension (Communication with Support Groups). Analysis of covariance revealed main effects for pretesting for two dimensions (Problem Solving and Communication with Supervisor) and a pretest-training interaction-for one dimension (Problem Solving). Except for one dimension, t tests revealed no significant differences between traditional pretests and retrospective pretests, thus negating a hypothesized response shift bias.

A Historical/Critical Analysis of the TV Series The Fugitive
In many respects, the popular 1960's television series, The Fugitive perfectly captured the swelling disillusionment with authority, alienation, and discontent that soon encompassed American society. This historical/critical study provides a broad overview of the economic, social, and political climate that surrounded the creation of The Fugitive. The primary focus of this study is the analysis of five discursive topics (individualism, marriage, justice & authority, professionalism, science and technology) within selected episodes and to show how they relate to broader cultural debates which occurred at that time. Finally, this study argues that The Fugitive is a part of a television adventure subgenre which we may classify as the contemporary "wanderer-hero" narrative and traces its evolution through selected television series from the last three decades.

Active or Passive Voice: Does It Matter?
This thesis reports on the use of active and passive voice in the workplace and classroom through analysis of surveys completed by 37 employees and 66 students. The surveys offered six categories of business writing with ten sets of two sentences each, written in active and passive voice. Participants selected one sentence from each set and gave a reason for each selection. The participants preferred active over passive 47 to 46 percent of opportunities, but they preferred mixed voice over both, 49 percent. The participants preferred active only for memos to supervisors; in the other five categories they preferred passive or mixed voice. Both males and females preferred mixed voice, and age appeared to influence the choices. They cited context as the most common reason for using passive.

From Isolation to Action: A Metaphoric Analysis of Franklin Roosevelt's Pro-Preparation Rhetoric
Virtually all studies on the presidential use of metaphor focus on one particular event and speech. These studies look only at speeches that justify military actions after they have already occurred, and these researchers seek to discover a relationship between the use of the metaphor and the public's support of a military action. In order to analyze the persuasive elements of President Franklin Roosevelt's rhetoric in developing popular and Congressional support for war preparation, this study seeks to answer three specific questions. To what extent does Franklin Roosevelt develop a common theme in selected speeches of war preparation immediately prior to World War II? To what extent was Roosevelt's development of this theme persuasive to the American public? What consequences can be anticipated if future presidents or speakers for social movements employ these procedures.

Children's Inferences Based on Brand Personality
This study explored the inferences male children held about the brand personality. The sample included 46 male fifth graders. Personal interviews were conducted and the results were compiled and interpreted using descriptive statistics. Four subject areas were addressed: identification and inferences about brand personality, sources of inferences, children's ability to make inferences about other children based on brand personality, and application of brand personality to self. Results indicated children make inferences about brand personality, make inferences about other children based on brand personality, and apply brand personality to themselves. An attempt to identify sources of inferences was inconclusive.

Test Order Effects on Children's Rorschachs
Thirty-three children from a community sample, ages 5 to 13, were administered the Rorschach Inkblot Test, along with projective Draw-an-Animal and Draw-a-Person tasks and other psychological measures. Subjects were randomly assigned to one of three test order conditions: Draw-an-Animal followed by the Rorschach, Draw-a-Person followed by the Rorschach, and Rorschach before any other projective test. The number of Human and Animal contents in the test records was examined. Analysis showed no significant differences among the three groups for production of the content variables, suggesting that the Rorschach Inkblot Test is relatively robust with respect to test order effects.

Female Sexual Victimization: Psychosocial Consequences
This archival and qualitative research adds insight into the psychosocial consequences females of sexual victimization incur. Sexual abuse is a pervasive, complex societal problem experienced by 30%-46% of American females. The psychosocial consequences are numerous, often severe, and can result in death. They include: anxiety, BPD, denial, dependence, despair, eating disorders, destructive relationships, fear, guilt, hallucinations, helplessness, hopelessness, hysteria, insecurity, isolation, MPD, nightmares, numbness, passivity, pessimism, phobias, PTSD, rage, self-loathing, sexual dysfunctions, shame, shock, sleeping disorders, stigmatization, stress-related disorders, substance abuse, and suicide. The severity of psychosocial consequences to female victims varies greatly depending upon the degree, duration, and emotion surrounding the abuse, the victim's health, and the health of the victim's social network. In conclusion, strategies suggested in the literature to combat female sexual victimization are outlined.

Hospitalized School-Age Children: Psychosocial Issues and Use of a Live, Closed-Circuit Television Program
This descriptive study utilized semi-structured interviews and observations to examine the experiences of hospitalized school-age children, and explore the potential of a live, closed-circuit television program as a psychosocial intervention. Among findings, Phase I data from 16 subjects indicates a) concern with painful medical procedures, particularly intraveneous (IV) injections, b) a desire for more information, especially concerning medical equipment, c) a variety of responses to social issues among subjects, d) the importance of activities, and e) the central role of the hospital playroom. Phase II data indicates that live, closed-circuit television can provide ambulatory and room-bound children opportunities for making choices, social interaction, participation, and information on their environment. Conclusions and implications are included.

Rhetoric as Praxis: A Model for Deconstructing Hermeneutic Discourse
This study proposes a model for the deconstruction of nationalism. Nationalism is a discursive construct. This construct manifests in ideologies and formalizes order. Individuals should question these institutions in order to achieve legitimate societal participation. This criticism can be accomplished through self-reflection. The model demonstrates that sanctioned individual(s) provide interpretations of events. These interpretations recycle authority. The hermeneutic obscures an individual's understanding of the originating fact. Self-reflection allows an individual, such as Malcolm X in the Nation of Islam, to come closer to discovering the original fact. Critiquing the hermeneutic can reveal the imperfections of the message(s). Revealing the imperfections of an ideology is the first step to the liberation of the individual and society.

Validity of the Health Belief Model as a Predictor of Activity in Younger and Older Adults
The present investigation assessed Health Belief Model (HBM) variables and a measure of physical activity for both younger and older adults. Results of discriminant analyses suggest HBM variables and physical activity can predict age-group membership with 89% accuracy. The younger sample (n = 88; M= 21.5 years) was significantly more anxious about aging, perceived more barriers to exercise, less control from powerful others, and more social support than the older sample (n = 56; M = 71.8 years). For the younger sample, those who perceived more benefits of exercise, had social support, were male, and were less anxious about aging were more active. For the older sample, those who perceived more benefits of exercise were more likely to be active.

An Experimental Analysis of Preference Problems in a Self-Control Choice Procedure by Adults with Mental Retardation
The original purpose of this study was to determine if Tegretol has an effect on the impulsive behavior exhibited by people with mental retardation. This was to be accomplished through a replication of the self-control choice procedures used by Ragotzy, Blakely, and Poling (1988). The procedure involved three stages. First, subjects chose between stimuli that provided either one or three edibles. Then the stimuli associated with the smaller and larger edibles were reversed. Following this, the procedure required the implementation of successively longer delays to the larger reinforcer. However, none of the subjects who participated was able to make the discriminations necessary to proceed, i.e., the subjects did not systematically select the stimulus associated with the larger magnitude edible choice. The identification and rectification of these errors in discrimination became the focus of this study. Various procedures were used to enhance discrimination, including fading, adjusting the magnitude of the edibles, and stimulus changes. None of these changes was successful in teaching the subjects the necessary discriminations.

The Effect of Creative Dramatics Activities on the Story Retellings of Kindergartners
The study was designed to determine the effect a dramatic play activity had on the content of a story retelling of kindergarten students. Approximately 35 students were randomly sampled to form experimental and control groups. Both groups engaged in a read aloud activity, followed by brief discussion, and an independent illustration of the story. The experimental group participated in a creative reenactment of the story prior to the illustration activity. Students in both groups then retold the story to the researcher. Retellings were transcribed and scored for: Story Retelling Analysis score (Morrow, 1988); percentage of characters recalled; percentage of plot episodes recalled; and the presence of story language, inferential statements, and a distinct beginning, middle, and end. Anecdotal data are described narratively.

The Angoff Method and Rater Analysis: Enhancing Cutoff Score Reliability and Accuracy
At times called a philosophy and other times called a process, cutting score methodology is an issue routinely encountered by Industrial/Organizational (I/0) psychologists. Published literature on cutting score methodology appears much more frequently in academic settings than it does in personnel settings where the potential for lawsuits typically occurs more often. With the passage of the 1991 Civil Rights Act, it is no longer legal to use within-group scoring. It has now become necessary for personnel psychologists to develop more acceptable selection methods that fall within established guidelines. Designating cutoff scores with the Angoff method appears to suit many requirements of personnel departments. Several procedures have evolved that suggest enhancing the accuracy and reliability of the Angoff method is possible. The current experiment investigated several such procedures, and found that rater accuracy methods significantly enhance cutoff score reliability and accuracy.

A Continuous, Nowhere-Differentiable Function with a Dense Set of Proper Local Extrema
In this paper, we use the following scheme to construct a continuous, nowhere-differentiable function 𝑓 which is the uniform limit of a sequence of sawtooth functions 𝑓ₙ : [0, 1] → [0, 1] with increasingly sharp teeth. Let 𝑋 = [0, 1] x [0, 1] and 𝐹(𝑋) be the Hausdorff metric space determined by 𝑋. We define contraction maps 𝑤₁ , 𝑤₂ , 𝑤₃ on 𝑋. These maps define a contraction map 𝑤 on 𝐹(𝑋) via 𝑤(𝐴) = 𝑤₁(𝐴) ⋃ 𝑤₂(𝐴) ⋃ 𝑤₃(𝐴). The iteration under 𝑤 of the diagonal in 𝑋 defines a sequence of graphs of continuous functions 𝑓ₙ. Since 𝑤 is a contraction map in the compact metric space 𝐹(𝑋), 𝑤 has a unique fixed point. Hence, these iterations converge to the fixed point-which turns out to be the graph of our continuous, nowhere-differentiable function 𝑓. Chapter 2 contains the background we will need to engage our task. Chapter 3 includes two results from the Baire Category Theorem. The first is the well known fact that the set of continuous, nowhere-differentiable functions on [0,1] is a residual set in 𝐶[0,1]. The second fact is that the set of continuous functions on [0,1] which have a dense set …

Service Delivery in Organizations for the Mentally Retarded
This study analyzes effective service delivery in organizations serving the mentally retarded. Qualitative organizational analyses of three community care facilities were compared to assess effectiveness. Data were gathered by systematic observations, field notes, documents, and employee interviews. Program analysis, the funding system of service delivery, and staff attitudes best indicated effective service. I concluded that effectiveness would improve by focusing on individual consumer needs and further defining service delivery.

Discursive Horizons of Human Identity and Wilderness in Postmodern Environmental Ethics: A Case Study of the Guadalupe Mountains of Texas
Using a genealogy of the narratives of the Guadalupes, I explore three moral identities. The Mescalero Apache exist as caretakers of sacred space. Spanish and Anglo settlers exist as conquerors of a hostile land. The park service exists as captives, imprisoned in the belief that economic justifications can protect the intrinsic value of wilderness. The narrative shift from oral to abstract text-based culture entails a shift from intrinsic to instrumental valuation. I conclude that interpretation of narratives, such as those of the Guadalupes, is not by itself a sufficient condition for change. Interpretation is, however, a necessary condition for expanding the cultural conversation beyond merely instrumental justifications to include caring for wilderness's intrinsic values.
