Selective Antagonism Of The Rate‐Decreasing Effect Of D‐Amphetamine By Chlorpromazine In A Repeated‐Acquisition Task, Donald M. Thompson
Selective Antagonism Of The Rate‐Decreasing Effect Of D‐Amphetamine By Chlorpromazine In A Repeated‐Acquisition Task, Donald M. Thompson
Faculty Publications
Pigeons acquired a different four‐response chain each session by responding sequentially on three keys in the presence of four colors. The response chain was maintained by food presentation under a fixed‐ratio schedule. When d‐amphetamine was administered alone, the overall response rate decreased and the percent errors increased with increasing doses. When a small dose of chlorpromazine, which was ineffective when given alone, was administered in combination with d‐amphetamine, the rate‐decreasing effect was antagonized. The antagonism was selective, however, in that the error‐increasing effect of d‐amprotamine was augmented by chlorpromazine. The nature of the joint effect of the two drugs thus …
Effects Of D‐Amphetamine And Cocaine On Strained Ratio Behavior In A Repeated‐Acquisition Task, Donald M. Thompson, Joseph M. Moerschbaecher
Effects Of D‐Amphetamine And Cocaine On Strained Ratio Behavior In A Repeated‐Acquisition Task, Donald M. Thompson, Joseph M. Moerschbaecher
Faculty Publications
Pigeons acquired a different four‐response chain each session by responding sequentially on three keys in the presence of four colors. When the fixed‐ratio requirement for food presentation was five completions of the chain, d‐amphetamine and cocaine disrupted the behavior. As the dose of each drug was increased, the overall response rate decreased, the overall accuracy was impaired (i.e., percent errors increased), and there was less within‐session error reduction (acquisition). In contrast, when the fixed‐ratio requirement was either 20 or 50 completions of the chain, certain doses of both drugs produced large increases in the overall response rate by eliminating the …
Effects Of D‐Amphetamine, Cocaine, And Phencyclidine On The Acquisition Of Response Sequences With And Without Stimulus Fading, Joseph M. Moerschbaecher, Donald M. Thompson
Effects Of D‐Amphetamine, Cocaine, And Phencyclidine On The Acquisition Of Response Sequences With And Without Stimulus Fading, Joseph M. Moerschbaecher, Donald M. Thompson
Faculty Publications
In each of three components of a multiple schedule, monkeys were required to emit a different sequence of four responses in a predetermined order on four levers. Sequence completions produced food on a fixed‐ratio schedule. Errors produced a brief timeout. One component of the multiple schedule was a repeated‐acquisition task where the four‐response sequence changed each session (learning). The second component of the multiple schedule was also a repeated‐acquisition task, but acquisition was supported through the use of a stimulus‐fading procedure (faded learning). In a third component of the multiple schedule, the sequence of responses remained the same from session …
The Application Of Bel Canto Concepts And Principles To Trumpet Pedagogy And Performance., Malcolm Eugene Beauchamp
The Application Of Bel Canto Concepts And Principles To Trumpet Pedagogy And Performance., Malcolm Eugene Beauchamp
LSU Historical Dissertations and Theses
Bel canto is a term of nebulous meaning and inconsistent usage. Probably the most comprehensive interpretation of bel canto is an ideal of vocal excellence, a vocal technique, and a style of performance identified with the seventeenth and eighteenth centuries. Recent publications concerning vocal pedagogy and performance practices illustrate an efflorescence of interest in bel canto. The significance of bel canto to contemporary vocal pedagogy has become a topic for theses and dissertations. In view of the revived interest in bel canto and its significance to contemporary vocal pedagogy, it is apparent that the teachings of the old bel canto …

The anionic chlorocomplexes of Pd(II), Ir(IV), Pt(IV), Au(III), Rh(III) and Ir(III) were floated from aqueous solutions with cationic surfactants of the quaternary ammonium type, RNR(,3)Br. The flotation behavior of each metal was determined with respect to variations of the surfactant primary, R, and secondary, R', chain lengths, the initial HCl concentration, the initial NaCl concentration, the …
Agrarian Political Economy: The Order Of Ends And Means., Andrew Warnie Foshee
Agrarian Political Economy: The Order Of Ends And Means., Andrew Warnie Foshee
LSU Historical Dissertations and Theses
From the earliest economic thought there has existed the notion that agriculture is the most preferred of all forms of economic activity. This preference is grounded in the belief that when agriculture is the dominant form of economic activity a set of ends will be attained which are consistent with human nature and conducive to human happiness. These are the ends of limited wealth, internal and external freedom, and piety. Writers expressing this belief were engaged in a study of political economy which was not bounded by the methodological strictures of logical positivism. For these agrarian political economists there existed …
A Quantitative Evaluation Of Landsat For Monitoring Suspended Sediments In A Fluvial Channel., Soon Tae Kim
A Quantitative Evaluation Of Landsat For Monitoring Suspended Sediments In A Fluvial Channel., Soon Tae Kim
LSU Historical Dissertations and Theses
Since the launch of Landsat-1 July, 1972, the orbital remote sensing system has made significant contribution to earth science research. Landsat's repetitive "earth observations" are of great value for monitoring changes in earth surface conditions through time. Investigation of suspended sediment concentrations in natural water bodies is one of the major areas of Landsat applications. An attempt has been made to evaluate the utility of Landsat Multispectral Scanner (MSS) digital data for monitoring suspended sediment concentrations in a natural river channel using Tarbert Landing, Mississippi on the lower Mississippi River as the test site. Specific purposes of the study were: …
Jack London's South Sea Narratives., David Allison Moreland
Jack London's South Sea Narratives., David Allison Moreland
LSU Historical Dissertations and Theses
Although Jack London is recognized as one of the most popular American fiction writers in the world, critics of American literary naturalism have tended to rank him considerably below the other well-known naturalists: Frank Norris, Stephen Crane, and Theodore Dreiser. The consensus has been that London wrote too much, too hastily, and weakened his art by imposing "ideas" (Darwinian, Spencerian, Nietzschean, Marxian) upon his narratives. However, in recent years a serious reevaluation of "the boy wonder of the naturalist carnival" has begun. As a master of the action narrative, Jack London, who both mirrored his age and anticipated later twentieth-century …
Group Influence And Cognitive Consistency As Determinants Of Value Change: A Methodological Analysis Of Self-Confrontation Theory., Mark L. Paris
Group Influence And Cognitive Consistency As Determinants Of Value Change: A Methodological Analysis Of Self-Confrontation Theory., Mark L. Paris
LSU Historical Dissertations and Theses
The present study attempted to either extend, modify or challenge Rokeach's (1973) Self-confrontation theory of value change. Rokeach (1973) found that subjects who were confronted with specific self-confrontation messages, which were designed to make differences between their value systems and self-concepts salient, were more likely than control subjects to change the rank-ordering of the values Freedom and Equality in a ranking task containing 18 values. Rokeach explained this phenomenon by invoking the concept of self-dissatisfaction, which he said subjects came to feel as a result of being exposed to the self-confrontation messages. The present study compared this explanation with the …
Speciation Of Environmental Pollutants By Gc-Aa And By Esca. Purification Of Water At Ultratrace Levels Of Heavy Metals And Complexation Studies By Electrochemical Methods., Ileana Aurea-Leon Rhodes
Speciation Of Environmental Pollutants By Gc-Aa And By Esca. Purification Of Water At Ultratrace Levels Of Heavy Metals And Complexation Studies By Electrochemical Methods., Ileana Aurea-Leon Rhodes
LSU Historical Dissertations and Theses
Speciation of environmental pollutants is essential for potential toxicity evaluations. It is important to determine what is the original chemical form of the pollutant when released in the environment as well as all possible reaction products and their potential hazards. The media through which these pollutants are transported in the environment are also of importance. Heavy metal pollutants usually occur in very low concentrations in the environment, therefore, very sensitive techniques are required for the determination of these metals. A GC-AA method was developed that allowed the simultaneous determination of PbEt(,4) and of PbEt(,3)Cl in gaseous and liquid samples. This …

A Film Analysis Of Motor Pattern Development Of Educable Mentally Retarded Children., Leonard Max Hill
LSU Historical Dissertations and Theses
The purpose of the study was to compare the standing long jump, place kick, overarm throw and striking patterns of educable mentally retarded children to the mature patterns of highly skilled individuals. It was also the purpose of this study to determine if these same motor patterns were inherent in educable mentally retarded subjects and to determine if these patterns would emerge naturally in a goal-centered teaching-learning environment. Eleven educable mentally retarded children between the ages of five and eight years were selected to participate in the study. The children participated in a one week (fifteen minutes per day) orientation …
Perceptions Of The Role Of Corporate Audit Committees - Now And In The Future., Brenda Stewart Birkett
Perceptions Of The Role Of Corporate Audit Committees - Now And In The Future., Brenda Stewart Birkett
LSU Historical Dissertations and Theses
Changes in the economy have brought about attempts to improve the structure of the corporate organization and the quality of corporate financial reporting. One such attempt has been to increase the responsibilities of corporate boards of directors, and subcommittees to handle specific duties of the board have been established. The audit committee is one of these subcommittees and is now required for all companies listed on the New York Stock Exchange. The corporate audit committee should make a significant contribution toward improving the integrity and credibility of financial statements and the overall corporate image in the public sector. To accomplish …
Investigation Of Effects Of Hypnosis, Relaxation, And Mental Rehearsal On Performance Scores Of Golfers And Runners., Julie Nelson
Investigation Of Effects Of Hypnosis, Relaxation, And Mental Rehearsal On Performance Scores Of Golfers And Runners., Julie Nelson
LSU Historical Dissertations and Theses
The purpose of this study was to investigate the benefit of hypnotic techniques, relaxation, and mental rehearsal for improvement in performance scores for golfers and runners. Treatments were designed to be similar to interventions reported to be successful with individual athletes yet unsupported by larger investigations. No significant results were obtained for either sport. Explanations for obtained results included an actual absence of true effect, masking of effects by continuing methodological problems in the area of athletics and hypnosis, and the lack of generalizability of positive effect. Well controlled, indepth case studies were recommended for future investigation.
The Confederate Defense Of Mobile, 1861-1865. (Volumes I-Ii)., Arthur William Bergeron Jr
The Confederate Defense Of Mobile, 1861-1865. (Volumes I-Ii)., Arthur William Bergeron Jr
LSU Historical Dissertations and Theses
The people of Mobile, Alabama, supported the secession of their state from the Union in January 1861, and thousands of her able-bodied men served in the Confederate army from 1861 to 1865. Recognizing the city's strategic importance as a port and major railroad center connecting the eastern and western sections of the new nation, the Confederate government moved quickly to provide adequate defenses for Mobile. Confederate soldiers occupied and began to strengthen Fort Morgan and Fort Gaines, which guarded the main channels leading into Mobile Bay. The Confederate Navy Department converted several steamers into gunboats and began construction of four …

Theory And Tests Of The Effect Of Financial Leverage On Valuation Of The Banking Firm., Donald Malcolm Chance
Theory And Tests Of The Effect Of Financial Leverage On Valuation Of The Banking Firm., Donald Malcolm Chance
LSU Historical Dissertations and Theses
The effect of financial leverage on valuation and shareholder wealth of the banking firm was examined both theoretically and empirically. It was assumed that market imperfections made possible the creation of a bank which would operate in capital, loan, and deposit markets. The valuation of equity shares was assumed to be described by Black's zero-beta version of the Capital Asset Pricing Model. Although the Black model is a perfect market model, it served as a framework within which imperfections could be introduced. A firm operating in a market without an intermediary was converted to a bank, charged with the responsibility …

Charismatic Communication And Faith Healers: A Critical Study Of Rhetorical Behavior., Todd Vernon Lewis
Charismatic Communication And Faith Healers: A Critical Study Of Rhetorical Behavior., Todd Vernon Lewis
LSU Historical Dissertations and Theses
Faith healing evangelists attract devoted followers who perceive these religious leaders as possessors of charisma. Charisma is a concept that is often applied to any leader/communicator whose eloquence, persuasion, transcendence, and personal aura set him or her apart from the average person. In this dissertation charisma is operationally defined, linked to a process of communication, and applied to the rhetorical behavior of three prominent faith healing evangelists: Aimee Semple McPherson (1890-1944), A. A. Allen (1911-1970), and Kathryn Kuhlman (1907-1976). A survey of selected theories of charisma provides elements for a synergistic "charismatic-communication-influence-process-model." The newly formed model amalgamates charisma research from …

Music Criticism In The New York Times And The New York Tribune, 1851-1876., Mark Curtis Mcknight
LSU Historical Dissertations and Theses
Reports and comments on daily events in newspapers provide an invaluable tool in the study of a particular period or area of research. This study is concerned with the music reviews in two New York newspapers, the Times and the Tribune, between 1851 and 1876. This period in the history of the United States was above all one of transition. Social upheaval prevailed as a result of the Civil War and the abolition of slavery. In addition, America was rapidly gaining ascendancy in science, technology, and as a major political power. This evolution at the broader national level was accompanied …

The impact of substitutes upon United States exports …
Theory And Performance Of Narrative Ambiguity In Selected Novels By John Hawkes., Carole Ellsworth Tallant
Theory And Performance Of Narrative Ambiguity In Selected Novels By John Hawkes., Carole Ellsworth Tallant
LSU Historical Dissertations and Theses
Narrative ambiguity, a concept which has only recently achieved prominence in literary criticism, has important implications for the performance of literature as well. Few studies exist which focus exclusively on narrative ambiguity. Most, instead, discuss the semantic kind. Recently, however, the increase of interest in the narrative form in general has precipitated interest in narrative ambiguity as well. In the field of the performance of literature, however, no one has investigated this phenomenon until now. The purpose of this study was to define and describe narrative ambiguity through an examination and identification of it both in theoretical writings and in …
