An Investigation Into the Relationship Between Media and Content

Description: The purpose of this study was to investigate the relationship between media and content in my work. I began a series of paintings in the fall of 1985 which was based on 35mm transparencies. At this point, the slides were nothing more than a visual aid, a way to augment my technical skills; my chief interest in these paintings was narrative. I was also taking a drawing class at the time, and several times I recycled a transparency I had used with a painting to create a drawing. Sometimes Both versions were relatively successful (though often for very different reasons), other times one version would be more successful than the other. Technical proficiency (or lack of it) did not seem to be the determining factor in these cases.

Fluorescence spectroscopic studies of DNA dynamics

Description: Random solvent induced motions of DNA are manifest as nanosecond torsional oscillations of the helix backbone, nanosecond through millisecond bending deformations and overall rotational and translational diffusion of the polymer. Fluorescence spectroscopy is used to study this spectrum of DNA motions while ethidium monoazide was covalently bounded. The steady state fluorescence depolarization data indicate that the covalent monoazide/DNA complex exhibits internal motions characterized by an average angular amplitude of 26 degrees confirming reports of fast torsional oscillations in noncovalent ethidium bromide/DNA systems. Data obtained by use of a new polarized photobleaching recovery technique (FPR) reflect both the rotational dynamics of the polymer and the reversible photochemistry of the dye. To isolate the reorientational motion of the DNA, the FPR experiments were ran in two modes that differ only in the polarization of the bleaching light. A quotient function constructed from the data obtained in these two modes monitors only the rotational component of the FPR recovery. In specific applications those bending deformations of long DNA molecules that have characteristic relaxation times on the order of 100 microseconds have been resolved. A fluorescence correlation technique that relates fluctuations in particle number to center-of-mass motion was used to measure translational diffusion on coefficients of the plasmid PBR322 and a short oligomeric DNA. A theory that describes angular correlation in systems exhibiting cyclic, biologically directed reorientation and random Brownian rotation is developed.

Alcohol and Drug Abuse Programs in Selected Universities in the South and Southwest

Description: The problem addressed in this study is how selected universities in the South and Southwest recognize and attempt to deal with alcohol use and other drug use among students. The purpose of the study was to determine current practices and policies concerning student alcohol and drug use among the 20 selected universities. The data were obtained by means of a descriptive survey questionnaire which was mailed to 20 selected universities under the jurisdiction of the Southern Regional Accrediting Board. The instrument was designed to identify practices and programs concerning student alcohol and drug use. A copy of each institution's alcohol and drug policy was requested. The content and procedures of the programs implemented by the responding institutions were reviewed, in order to evaluate the extent and degree to which they provide for the recognition, education, intervention, and treatment for students with alcohol- or drug-use problems. Results are presented in tabular form. Of the 20 major state-supported universities which were mailed questionnaires, 75% returned usable instruments. All responding institutions felt they have an alcohol or drug problem of some magnitude, and all either have, or believe they have, some kind of policy to deal with substance use by students. All of the responding institutions also indicate that they have various programs in operation which deal with student substance use and abuse. Since this was a regional study the results are not necessarily generalizable. On the basis of the literature reviewed and the survey responses received, an authentic problem with student alcohol and drug use exists on campus. The institutions surveyed appear to recognize a problem; however, the results of this study reveal that most have yet to develop an effective or coordinated strategy to combat student alcohol and drug abuse.

Anglo-American Relations and the Problems of a Jewish State, 1945- 1948

Description: This thesis is concerned with determining the effect of the establishment of a Jewish state on Anglo-American relations and the policies of their governments. This work covers the period from the awarding of the Palestine Mandate to Great Britain, through World War II, and concentrates on the post-war events up to the foundation of the state of Israel. It uses major governmental documents, as well as those of the United Nations, the archival materials at the Harry S. Truman Library, and the memoirs of the major participants in the Palestine drama. This study concludes that, while the Palestine problem presented ample opportunities for disunity, the Anglo-American relationship suffered no permanently damaging effects.

Assessing the Use of Microcomputers by Administrators in Higher Education in Oklahoma

Description: This study was conducted to examine the use of microcomputers and other computers by top administrators in the twenty—seven public colleges and universities in Oklahoma; to assess the impact that training and other factors have on the extent to which microcomputers are being used; and to identify trends in administrative computer usage. The survey technique was utilized in collecting the data for this study. The survey instrument was developed for use in this study from a review of the literature, an evaluation by a panel of judges, and a pilot study. The survey instrument was sent to the administrators for business, academic, and student affairs via the president of each university in the 1986 spring and summer semesters. Seventy-four of the eighty-one or 91.4 percent of the administrators responded. Following is a summary of the major findings of this study. 1. Fourteen of the seventy-four or 18.9 percent of the respondents personally use a microcomputer and 51.3 percent of the respondents have someone use a microcomputer on their behalf. 2. The most prevalent use of microcomputers is word processing; the most prevalent uses of mainframes are word processing and database management; and the majority of the respondents do not use a computer for spreadsheets, graphics, database management, telecommunications, and time management functions. Computer functions rated highly important are word processing, spreadsheets, and database management. 3. Administrators feel they need more training in the use of computers. 4. Conditions affecting the use of microcomputers are an established process for evaluating software, funding for maintenance, and practice time. 5. Age is negatively correlated to the personal use of microcomputers. 6. Administrators believe that in the near future, the use of microcomputers will increase, the use of mainframes will remain about the same, and the number of jobs done without computers will decrease.

A Behavioral Modification Analysis of the Effects of Multimedia First Aid Training on Injuries in an Industrial Setting

Description: Past research has shown a correlation between first-aid training and the reduction of injuries. This connection has been noted in off-the-job situations in addition to industrial studies. This project is an extension of those past findings with three notable differences: total population training was studied, as the intervention instead of just saturation treatment; attention was given to the effect that the half-life of training had upon injury reduction; and three randomly chosen small groups we're studied to determine short range effects. The theoretical bases from which the study hypothesis was developed originated in the Behavioral Science and Psychology literature. Discussions are developed around the mental structuring of accidental potential situations in the case of a person trained in first-aid principles. Behavior Modification was one of the principles of change that offered a.safer environment through first-aid training. Group contagion provided the setting for development of a safer place to work because of socialization to a "safe attitude." The intervention, American National Red Cross Standard Multimedia First-Aid Course, provided some of the mental developments toward modification of behavior. These were the modeling and rehearsal features of the course. A connection between group deviance and accident "proneness" led to a proposal that avoidance behavior was the resultant of the training.

Brainstem Gangliosides in Suddden Infant Death Syndrome

Description: Recent studies have shown that the Sudden Infant Death Syndrome (SIDS) is related to abnormal control of respiration (Ischemic degeneration of the brainstem may play an important role in altered respiratory control leading to death). In our studies we have examined brainstem ganglioside compositions in samples derived from SIDS victims and appropriate controls. Gangliosides are acidic glycosphingolipids that contain sialic acid. The high concentration of gangliosides in the central nervous system (CNS) implies that these lipids play an important role in CNS function. Some studies have indicated that gangliosides may function as receptor site determinants or modifiers, and in neural transmission. In our studies we used the Tettamanti, et al methodology to extract gangliosides, and High Performance Thin Layer Chromatography (HPTLC) and laser densitometry techniques for ganglioside analysis. The results of these analyses are being employed to establish lipid profile patterns to determine if there are significant variations in these lipid patterns between SIDS and control groups.

Characterization of the Pigment-Protein and Pigment-ester of Xanthomonas Campestris Pv. Juglandis

Description: The objectives of this project were to develop a high performance liquid chromatographic method for separating the pigment esters mixture, to determine the locations of the pigment moiety in the isolated esters using pholosiphases, and to characterize the pigment-protein complex and determine its distribution in other bacteria. Saponification of the two pigment esters 1 and 2 with aqueous KOH yielded two free pigments on TLC plates developed by two solvent systems. The fasters moving of these two free pigments co-chromatographed with the one free pigment produced from each pigment ester by phospholipase A2 treatment. This suggests that the pigment molecule is a methoxy derivative of xanthomonadin and is esterified to the 2-position of the glycerol moiety of each pigment ester. No free pigment was released from phospholipases C and D treatment of the two pigment esters, indicating that pigment is not esterified to the sorbitol or phosphate moiety of pigment esters 1 or 2.

Colony-Stimulating Factor from Umbilical Cord Endothelial Cells

Description: Conditioned media prepared from umbilical cord (UC) segments or endothelial cells (EC) contain colony stimulating activity, Both UCCM and ECCM were partially purified by DEAE-Sepharose and ACA44 gel filtration chromatography. The molecular weights were estimated as 25,000 and 31,000 for UC-CSF and EC-CSF, respectively. UC-CSF was further fractionated by Con A Sepharose, IEF and HPLC on a hydrophobic phenyl column. The highly purified CSF stimulates human macrophage and granulocyte colony formation, indicating it is GM-CSF in nature. Characterization studies have revealed that both CSFs are heat stable at 60°C for 30 min. They are sensitive to digestion by protease and to periodate oxidation but are stable to treatment with sulfhydryl reagents. The synthesis of CSF in endothelial cells is inhibited by actinomycin D, cycloheximide and puromycin, indicating that protein and RNA synthesis are required for CSF production. Among the mitogens tested, only LPS exhibited stimulatory activity on the production of CSF. Metabolic modulators such as dibutyryl cAMP, isobutylmethylxanthine, PGE2 and lactoferrin inhibit CSF production, while PGF2 enhances CSF production.

A Comparison of Recall by University Bible Students After Discussion and After Self-Study

Description: Recall of expository prose after one of two learning techniques was determined. Pearson correlation did not discover a significant difference between the recall writings of the examinees who studied by discussion and those who studied by underlining. The significance of the difference between two proportions found that the group which underlined recalled significantly better than the group which discussed what they had read. This highly significant difference was almost identical when all synonyms from the Turbo Lightning computer program were considered correct recall and analyzed by the significance of the difference between two proportions.

A Comparison of Some Continuity Corrections for the Chi-Squared Test in 3 x 3, 3 x 4, and 3 x 5 Tables

Description: This study was designed to determine whether chis-quared based tests for independence give reliable estimates (as compared to the exact values provided by Fisher's exact probabilities test) of the probability of a relationship between the variables in 3 X 3, 3 X 4 , and 3 X 5 contingency tables when the sample size is 10, 20, or 30. In addition to the classical (uncorrected) chi-squared test, four methods for continuity correction were compared to Fisher's exact probabilities test. The four methods were Yates' correction, two corrections attributed to Cochran, and Mantel's correction. The study was modeled after a similar comparison conducted on 2 X 2 contingency tables and published by Michael Haber.

A comparison of the Effects of Different Sizes of Ceiling Rules on the Estimates of Reliability of a Mathematics Achievement Test

Description: This study compared the estimates of reliability made using one, two, three, four, five, and unlimited consecutive failures as ceiling rules in scoring a mathematics achievement test which is part of the Iowa Tests of Basic Skill (ITBS), Form 8. There were 700 students randomly selected from a population (N=2640) of students enrolled in the eight grades in a large urban school district in the southwestern United States. These 700 students were randomly divided into seven subgroups so that each subgroup had 100 students. The responses of all those students to three subtests of the mathematics achievement battery, which included mathematical concepts (44 items), problem solving (32 items), and computation (45 items), were analyzed to obtain the item difficulties and a total score for each student. The items in each subtest then were rearranged based on the item difficulties from the highest to the lowest value. In each subgroup, the method using one, two, three, four, five, and unlimited consecutive failures as the ceiling rules were applied to score the individual responses. The total score for each individual was the sum of the correct responses prior to the point described by the ceiling rule. The correct responses after the ceiling rule were not part of the total score. The estimate of reliability in each method was computed by alpha coefficient of the SPSS-X. The results of this study indicated that the estimate of reliability using two, three, four, and five consecutive failures as the ceiling rules were an improvement over the methods using one and unlimited consecutive failures.

A Construct Validation Study of the Relationship Between Interpersonal Behavior Styles as Described by the Social Style of Behavior Profile and Leadership Styles as Described by the Leader Behavior Analysis

Description: The extensive use of leadership training in industry suggests a need for validated information concerning the role of interpersonal behavior in the study of leadership styles. Early leadership research focused primarily on the traits of a leader. Subsequent research has attempted to f a correlation between leader behavior and personality type. Findings indicate that personality typologies, which include attitude and value constructs, are too broad to explain leader behavior. In order to move toward specificity in the study of leadership, it is necessary to determine if interpersonal behavior styles are related to leader behavior. The purpose of this study was to investigate the relationship of variables from data gathered on leadership styles from the Leader Behavior Analysis and variables related to interpersonal behavior reported from the Social Style of Behavior Profile. The dimensions of leadership style flexibility and social style of behavior versatility were also examined. A random sample of 100 corporate employees were used in this study. The research instruments that were tested for independence were the Leader Behavior Analysis and the Social Style of Behavior Profile. The results of this study indicate that the constructs of leadership style and social style are independent dimensions. Additionally, the results of the study indicate that the constructs of leader flexibility and social style versatility are independent dimensions.

Containment Relations Between Classes of Regular Ideals in a Ring with Few Zero Divisors

Description: This dissertation focuses on the significance of containment relations between the above mentioned classes of ideals. The main problem considered in Chapter II is determining conditions which lead a ring to be a P-ring, D-ring, or AM-ring when every regular ideal is a P-ideal, D-ideal, or AM-ideal, respectively. We also consider containment relations between classes of regular ideals which guarantee that the ring is a quasi-valuation ring. We continue this study into the third chapter; in particular, we look at the conditions in a quasi-valuation ring which lead to a = Jr, sr - f, and a = v. Furthermore we give necessary and sufficient conditions that a ring be a discrete rank one quasi-valuation ring. For example, if R is Noetherian, then ft = J if and only if R is a discrete rank one quasi-valuation ring.

A Descriptive Analysis of Political Campaign Advertising of the 1972 Presidential Campaign

Description: The purpose of this research was to determine the aural and visual issues present in televised political campaign advertising of the 1972 Presidential election year. Content analysis was the method employed to determine these issues. The campaign commercials of George McGovern and Richard Nixon were the subject of the analysis. The issues coded were Social Welfare, Natural Resources, Labor, Management, Civil Rights, Economy, Foreign Affairs, Vietnam, Government, Public Order, Defense, Republicans, and Democrats. The results show that the campaigns used issues appearing in network news coverage, the percentage of time each campaign spent on the issues, and that the aural content was supported by the visual images in the commercials.

A Descriptive History of Wesley College

Description: The American junior colleges of today are historical accidents, some having begun originally with elementary and secondary divisions or as adjuncts of local high schools. Wesley College in Greenville, Texas, began on a two acre campus as North Texas University Training School in Terrell, Texas, in 1905. Chartered by the North Texas Conference of the Methodist Episcopal Church, South, the school initially provided elementary and high school and two years of college. At this time the name was changed to Wesley College, but the school closed in the spring of 1911. It reopened on a twenty acre campus in the fall of 1912 in Greenville, Texas, and maintained a close relationship with that city until mounting financial problems forced closure in 1938. Many records of the school were transferred to Southern Methodist University at Dallas, and in 1939, Wesley College alumni were invited to become associate members of the S.M.U. Ex-Students Association. Many associated with Wesley College continue to meet annually in Greenville to keep alive their memories of the once prestigious college. This study employs primary and secondary documentary data, as well as interviews with fifty-six individuals, to provide a chronological descriptive history of the origin, growth, development, and demise of the school, together with its philosophical bases.
