Extensions Of L-Homomorphisms, Eleanor R. Aron, Anthony W. Hager, James J. Madden

Faculty Publications

It is shown that, in abelian l-groups, each morphism to a complete vector lattice extends over any majorizing embedding. This extends a result of the first author for Archimedean f-algebras with identity, and the recent Luxemburg-Schep theorem for vector lattices, and solves a problem of Conrad and McAlister. The proof presented here differs substantially from the Luxem- burg-Schep proof. Ours uses the Yosida representation and Gleason’s theorem on topological projectivity—this is novel, and seems relatively economical and transparent. The l-group theorem is shown to imply, and with some modestly categorical machinery, to be implied by, certain similar statements in subcategories …

An Empirical Investigation Of The Differential Market Response To Quarterly Earnings Announcements., Salem Mohamed Bengharbia

LSU Historical Dissertations and Theses

The primary objective of this study was twofold. First, to examine the information content of quarterly earnings announcements. Second, the effects of firm size, timeliness of earnings announcements, price-earnings ratio, industry, sign, and magnitude of unanticipated earnings on market response were examined. The research procedure employed the market residual analysis technique to determine how the market behaves in response to earnings reports. The research sample consisted of 319 firms representing ten major industries. A total of 1657 quarterly earnings announcements were made by these firms over a two-year period. The data for this study were collected from the Wall Street …

The Vertebrate Paleontology Of Late Pleistocene (Rancholabrean) Mammalian Sites Of Louisiana, Linda L. Rice

LSU Historical Dissertations and Theses

This thesis describes the late Pleistocene (Rancholabrean) vertebrate paleontology of Louisiana through the use of vertebrates as paleoenvironmental indicators. This method of interpretation is established through morphological description and evaluation, taphonomy, systematic paleontology, and in some cases, the use of modern analogs.

This study compares and contrasts Louisiana with other southeastern states during the late Pleistocene. This comparison shows that Louisiana did not vary significantly from the rest of the southeastern United States during the late Rancholabrean. This work also shows that the most common habitats of Louisiana at this time were open temperate woods, grasslands, and marshes. Geographically, most …

Frontier Port On The Mississippi: A History Of The Legend Of Natchez Under-The-Hill, 1800-1900, Michael Francis Beard

LSU Historical Dissertations and Theses

Natchez Under-the-Hill, from 1800 to 1840 the second leading river port on the Mississippi, played a central role in the economic life of the Old Southwestern frontier. Despite this, it was chiefly known to contemporaries in both America and abroad as a center of intemperance, prostitution, gambling, and violence.

During the antebellum years this image of the Natchez waterfront was a symbol of the Myth of the Wild and Savage West, which assumed Westerners were violent, immoral, and uncivilized. The lawlessness and vice of the port, widely touted in travel journals and newspapers, provided evidence to non-westerners that their perceptions …

Control Algorithms, Tuning, And Adaptive Gain Tuning In Process Control., Alberto Arner Rovira

LSU Historical Dissertations and Theses

Controller tuning relationships based on optimizing the response of a first order lag plus dead time process are developed for proportional-plus-integral (PI) and proportional-plus-integral-plus-derivative (PID) control algorithms. Minimum error integrals were used as criteria of performance for the feedback control loop. The relationships presented are shown to provide excellent response characteristics in particular for processes where little or no overshoot is desired. The effect of applying the proportional action to the feedback variable in a PI control algorithm is analyzed and found to provide a more consistent response to set point changes and load changes than the conventional PI algorithm, …

Cell-Free Biosynthesis Of Erythroglycan In A Microsomal Fraction From K-562 Cells, T. Z. Russin, R. A. Laine, S. J. Turco

Faculty Publications

Particulate membrane preparations from K-562 [human CML (chronic-myelogenous-leukaemia)-derived] cells catalyse the transfer of [3H]galactose from UDP-[3H]galactose and [3H]N-acetylglucosamine from UDP-[3H]N-acetylglucosamine into an endogenous product that on digestion with Pronase yields long-chain glycopeptides (mol. wt. 7000-10000) called 'erythroglycan'. Incorporation of either labelled sugar increased up to 60 min of incubation time. The labelled erythroglycan was isolated by chromatography on Sephadex G-50 and characterized by digestion with endo-β-galactosidase from Escherichia freundii, followed by analysis on Bio-Gel P-2 and paper chromatography. This digestion gave the following four products: (1) a disaccharide with the sequence βGlcNAc-βGal; (2) a trisaccharide with the sequence βGal-βGlcNAc-βGal; (3) …

Selective Antagonism Of The Error‐Increasing Effect Of Morphine By Naloxone 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. The response chain was maintained by food presentation under a fixed‐ratio schedule. Errors produced a brief timeout but did not reset the chain. When either morphine or naloxone was administered alone, the overall response rate decreased with increasing doses. The rate‐decreasing effect was accompanied by an increase in percent errors with morphine but not with naloxone. Both effects of morphine were antagonized by doses of naloxone that were ineffective when given alone. The antagonism was selective in that naloxone (3 …

The Austrian Problem Of Language And Peter Handke: A Documentation., Donald Russell Bailey

LSU Historical Dissertations and Theses

Linguistic skepticism and the resultant awareness of the limits of language can be traced back to Hamann, Herder, and Humboldt, through Romanticism and French Symbolism, up to modern times. What has come to be called the crisis of language (Sprachkrise) can be viewed as one segment of a broader, multi-media phenomenon. The intensity of this crisis is concentrated in Austro-Hungary in the waning days of the Habsburg Monarchy. From this time forward supersensitivity to language remains a strongly Austrian phenomenon and can be followed through the European, German-language, and Austrian movements of this century, up to the founding of the …

The Regulation And Conservation Of Petroleum Resources In Louisiana, 1901-1940. (Volumes I And Ii)., Brady Michael Banta

LSU Historical Dissertations and Theses

This dissertation examines the State of Louisiana's policies and programs for the conservation and regulation of petroleum resources during the period 1901-1940. Where possible, it explores the relationship between Louisiana's regulatory policies and those of other petroleum-producing states, but it offers no comparative judgments regarding the effectiveness and success of these policies. Furthermore, the study considers contemporary federal policies and programs only when they had a direct influence on actions taken or decisions made by state officials in Louisiana. Within the limitations set forth above, this study explores the development, implementation, and effectiveness of Louisiana's petroleum conservation programs; the administrative …

The Anglo-Saxon And Norman "Eigenkirche" And The Ecclesiastical Policy Of William I., Albert Simeon Cote Jr

LSU Historical Dissertations and Theses

The eigenkirche or proprietary church was an important factor in the ecclesiastical policy of William I. In previous studies, the proprietary church was considered purely a local phenomenon. William's religious concerns in Normandy and England demonstrate the eigenkirche's role at the local, royal, and international levels. An examination of the legal sources is critical to understanding the proprietary church in Anglo-Saxon England, Normandy, and Norman England. The Anglo-Saxon charters provide important examples of the private church and monastery in the pre-Conquest period. In Normandy, the ducal charters, once inaccessible because of archival problems, are now available for analysis of the …

An Instructional Sequence In Experimental Design And Statistics For Graduate Music Therapy Students., Anthony Arthur Decuir

LSU Historical Dissertations and Theses

The purpose of this study was to develop a course in experimental design and statistics for graduate music therapy students. This study was developed in order to address, specifically, research problems in music therapy. Two recent independent studies of graduate research projects of music therapy studies indicated that the chief deficiencies were inadequate research designs and the under-utilization of statistical devices. As an addendum to the development of the course, a survey of the statistical course offerings in graduate and undergraduate music therapy curricula was conducted. The sixty-four music therapy departments approved by the National Association for Music Therapy were …

The Female Archetypes In Swinburne's Early Work, 1857-1871., Betty Moss Duffy

LSU Historical Dissertations and Theses

From "Queen Yseult," 1857, to "Hertha" of Songs before Sunrise, 1871, three archetypes--the femme fatale, the Terrible Mother, and the androgyne--dominate Swinburne's poems, dramas, and novels. These archetypes project the dominant artistic conflict of the Victorian period, the controversy over the function of art and the role of the artist, for they symbolize the psychological and cultural conflict between the doctrine of art for art's sake and its antithesis, art for morality's sake. The femme fatale becomes a symbol of art and beauty, the goal of the artist-androgyne's aesthetic quest. Her masochistic lover strives to possess beauty in the form …

The Efficacy Of Computer-Based And Tape-Recorded Assistance In Second-Semester Freshman Ear-Training Instruction., Janet Claire Garton

LSU Historical Dissertations and Theses

Harmonic dictation materials available in the Ear-Training Laboratory at Louisiana State University were programmed for computer presentation in order to observe the effects of the computer medium in comparison to the traditional laboratory approach. In accordance with the Solomon Four-Group Design, the sixty-two second-semester freshman music theory students were assigned randomly to computer and tape groups. Half of each group was assigned at random to take a pretest which was designed by the experimenter. After six withdrawals from the course, a total research population of fity-six students remained.

Task Accomplishment Ability Of Children In Small Groups., Nancy Larson Gennuso

LSU Historical Dissertations and Theses

The primary purpose of this study was the investigation and analysis of the behavior of small groups of children in a task accomplishment situation. The secondary purpose was to ascertain the effects of a group discussion generated by questions adapted from creative problem solving techniques. A review of literature revealed a lack of research on small groups of children in these areas. Thirty-six small groups of fourth and fifth grade children worked in groups of four on two construction-type tasks, one for pretest and one for posttest. Eighteen of the groups served as experimental groups and participated in the group …

Homosexualities: A Study Of Types., D'Lane Sally Miller

LSU Historical Dissertations and Theses

With 102 male homosexual and 12 male heterosexual Ss, this study explored the possibility that a typology of homosexuality could be developed using an expanded definition of homosexuality. Proposed dimensions were the variables: gender identity, social sex role, sexual orientation, overt sexual behaviors, current psychological status, and parent-child relations. Ss were recruited by a variety of methods and demographic characteristics suggest a fairly heterogeneous sample was obtained. Scores obtained from a battery of six tests were factor analyzed using an oblique (promax) rotation. Eight factors were obtained and factor pattern scores were used in two hierarchical cluster analysis methods (Johnson, …

Status And Prestige As A Factor In Brazilian Foreign Policy, 1905-1908., William Neal Nelson

LSU Historical Dissertations and Theses

This study traces the two traditional Brazilian foreign policy objectives of securing recognition as an important member of the international community, and friendship with the United States, during the period 1905-1908. These two objectives are examined in the light of Brazilian concern for status and prestige at the personal, national, and international levels. The themes of gaining international recognition, and Brazilian-American friendship are interwoven with the interpersonal relations that developed on the occasion of the Second Hague Peace Conference. The Second Hague Conference (1907) was the first global meeting in which Brazil was represented. It was an opportunity for Brazil …

Indigenism And Feminism In The Prose Fiction Of Rosario Castellanos., George Alexander St. John Robinson

LSU Historical Dissertations and Theses

The novel of Indian concern has had a long vogue in Latin America, where it is known alternately as novela indianista or novela indigenista. This tradition in the novel has produced such well known works as Lopez y Fuentes' El indio, Alcides Arguedas' Raza de bronce, Jorge Icaza's Huasipungo and Ciro Alegr(')ia's El mundo es ancho y ajeno, all published between 1919 and 1941. These novels seek to illustrate the deplorable conditions of life in Indian communities from Mexico to Bolivia. In so doing, however, the Indian characters of these novels are generally reduced to single dimensional characters devoid of …

A History Of Jefferson Barracks, 1826-1860., Byron Bertrand Banta Jr

LSU Historical Dissertations and Theses

Jefferson Barracks was established in 1826 and was one of the army's major posts until 1860. Located twenty-six miles below the confluence of the Missouri and Mississippi Rivers, the Barracks served as a concentration point for supplies for the various army installations in the Missouri River valley and along the upper Mississippi and its tributaries. When Jefferson Barracks was established, the army intended for the post to act as the Infantry School of Instruction, but the School was never formally organized. The first soldiers stationed at the post were required to construct their own barracks and other auxillary buildings, and …

A Study On Teacher Morale At A Selected Secondary School., Mark Fickie

LSU Historical Dissertations and Theses

The intent of the study was to investigate the morale of teachers in a selected south Louisiana secondary school. Four null hypotheses were proposed and tested to identify the effect of a change of facility upon the entire group of teachers; male and female teachers; teachers under the age of thirty-seven and those who were thirty-seven years of age or older; and teachers having bachelors degrees and teachers with higher degrees that moved to a new school plant. All forty-three teachers (N = 43) employed at a selected secondary school participated in the experiment. Of that total, nineteen teachers moved …

Patterns Of Development Of Independent Oil Companies In Louisiana: An Exploratory Study Into The Strategic Changes Of Growing Companies., David Lester Duhon

LSU Historical Dissertations and Theses

This study was conducted to gain additional knowledge about the process of change as entrepreneurships in the oil industry grow and develop. Thirty independent operators comprised the sample. The owner/manager of each firm was questioned at length about the growth of his company. Particular attention was given to identifying the relative stage of development of each firm. This was determined by analyzing the strategic characteristics identified in the literature as descriptive of stages of development. The evidence seriously questions the applicability of the stages of development model for these companies. The data strongly suggests that growth is a more gradual …

A Study Of The Effects Of Marketability On The Distribution Of Market Generated Returns., Bruce Loren Mcmanis

LSU Historical Dissertations and Theses

Very little theory has been developed on the effect of marketability on the distribution of returns. As a result, this study is an empirical exploration of that relationship, without any strong, preconceived hypotheses. Since the distributions were likely to be non-normal, but otherwise indeterminate as to form, a test had to be developed to determine the existence of differences. It was decided that the first four moments and the studentized range could effectively capture the characteristics of a distribution and provide a set of measures to serve as variables in discriminant analyses. Marketability was defined as shares traded divided by …
