Boardinghouses, Parties And The Creation Of A Political Society: Washington City, 1800-1830, Cynthia Diane Earman
Boardinghouses, Parties And The Creation Of A Political Society: Washington City, 1800-1830, Cynthia Diane Earman
LSU Historical Dissertations and Theses
Washington's elite society was a political society where members of Congress, the president, members of his cabinet, Supreme Court justices, and members of the diplomatic corps met with members of the press, and other visitors to the capital, and long term residents came together to form a unique society. This study evolved from the premise that James Sterling Young's view of Washington City was flawed. Three questions guided this project: How did Washington change over time?; Why were specific boardinghouses chosen?; and What role did elite wives play in the Washington community? Washington's elite community was by definition a political …
Solid-State Nmr Studies Of Organometallic Complexes, Ae Ja Kim
Solid-State Nmr Studies Of Organometallic Complexes, Ae Ja Kim
LSU Historical Dissertations and Theses
Solid-state NMR spectroscopy has been used to obtain information about electronic structure and molecular geometry for some organometallic complexes. The principal elements of the 13C chemical shielding tensor for a dimetallocyclopropane unit and three square-planar metal cyanides have been determined from a nonlinear least squares fit of the chemical shift powder pattern. For the dimetallocyclopropane unit, the orientation of the chemical shielding tensor with respect to the molecular axis has been assigned based on the dipolar coupling tensor. The principal elements of the 13P chemical shielding tensor for three binuclear platinum diphosphite complexes have been obtained from a …
Nietzsche And Heraclitus, Virginia Lyle Jennings Howard
Nietzsche And Heraclitus, Virginia Lyle Jennings Howard
LSU Historical Dissertations and Theses
Nietzshe's philosophical ideas are closely based upon his early studies of Greek thought. Unless his philosophy is approached from the standpoint of its foundation in the ancient Greeks, Heraclitus in particular, then it can be difficult to gain a coherent picture of Nietzsche's thought. In Heraclitus he found an affirmation of precisely what he loved about the ancient Greek way of life, its most fundamental concept: the contest. The Greeks embrace their apparently terrible characteristics and control them with a rule-governed contest. In the same way Heraclitus's universe consists of opposites which strive for dominion, not through wars of annihilation, …
The Role Of Bovine Herpesvirus-1 Glycoprotein Iii In Molecular Pathogenesis And Immunomodulation., Katherine Marie Byrne
The Role Of Bovine Herpesvirus-1 Glycoprotein Iii In Molecular Pathogenesis And Immunomodulation., Katherine Marie Byrne
LSU Historical Dissertations and Theses
Bovine herpesvirus-1 (BHV-1) is the pathogenic agent for infectious bovine rhinotracheitis. Current vaccines to protect against infection have serious disadvantages to producers and have been implicated in epizootic outbreaks. The virus has also been shown to cause suppression of the immune system. BHV-1 vaccines could be improved by identifying and genetically deleting those aspects of the virus responsible for immunosuppression and providing a marker within the genome which would distinguish the vaccine strain from wild types in the case of disease outbreaks. This study examined the role of gIII in viral infection and immunosuppression. This was accomplished by expressing full …
Cultural Studies And The Multicultural Curriculum., Mary Susan Huddleston Edgerton
Cultural Studies And The Multicultural Curriculum., Mary Susan Huddleston Edgerton
LSU Historical Dissertations and Theses
Although some of the most recent work in the field of multicultural education has acknowledged and begun to theorize about what has been called the new cultural politics of difference, problems concerning the very notions of marginality, boundaries, and their accompanying "essentialist" thought remain undertheorized. It is my intention to bring discussions about marginality and essentialism from literary theory, feminist psychoanalytic theory and poststructuralist philosophy more explicitly into the conversation about multicultural curriculum theorizing. In this study I have attempted to further develop this conversation around notions of "translation" as generated by philosophers Michel Serres (1982) and John Rajchmann (1991) …
Impact Of The Preservice Field Experience In Foreign Language Teaching: A Study Of The Development Of Preservice Teachers' Perspectives In Foreign Language Teaching. (Volumes I And Ii)., Denise Egea-Kuehne
LSU Historical Dissertations and Theses
Within the broader issue of teacher education, the focus of this study is on one of the most neglected areas of inquiry in the field of foreign languages, the preservice field experience, and the development of student teachers' perspectives of foreign language teaching. The following questions were specifically addressed: (1) What perspectives of foreign language teaching do student teachers hold upon completion of their program of university courses? (2) Is there an alteration of student teachers' perspectives of foreign language teaching during their student teaching semester? (3) What factors appear to influence student teachers' perspectives of foreign language teaching during …
Distinctions Between Reefs And Bioherms Based On Studies Of Fossil Algae: Mizzia, Permian Capitan Reef Complex (Guadalupe Mountains, Texas And New Mexico) And Eugonophyllum, Pennsylvanian Holder Formation (Sacramento Mountains, New Mexico)., Brenda Kirkland George
LSU Historical Dissertations and Theses
The udoteacean alga Eugonophyllum is well-preserved in the Virgilian Holder Formation, Sacramento Mountains. Original aragonite occurs as a felt-like mesh of needles in algal thalli, mollusc fragments, sponge walls, botryoidal, and isopachous marine cements. In the basal, heavily calcified portion of Eugonophyllum the interior of the thallus is composed of aragonitic felt punctuated by 20 $\mu$m diameter, parallel siphons. In the distal, less calcified portion of the thallus, irregularly arranged siphons are larger. This study substantiates suggested similarities between Pennsylvanian/Permian phylloid algal mounds and Holocene Halimeda mounds. The Permian dasyclad Mizzia is important for paleoecological study in the Guadalupe Mountains, …
The Relation Between Stress And Insulin-Dependent Diabetes Mellitus: Physiologic Arousal Or Disruption Of Compliance?, Virginia Diane Garrett
The Relation Between Stress And Insulin-Dependent Diabetes Mellitus: Physiologic Arousal Or Disruption Of Compliance?, Virginia Diane Garrett
LSU Historical Dissertations and Theses
The relations between minor life events, compliance, urinary free cortisol, and blood glucose in 40 adults with insulin-dependent diabetes mellitus was examined. Specifically, this study explored whether naturally-occurring minor stressful events had disruptive effects on metabolic control through: (a) an arousal mechanism mediated by cortisol, (b) disruption of the individual's adherence to prescribed treatment, (c) a combination of arousal and disruption of compliance, or (d) a third, unspecified mechanism. Stress did not influence metabolic control, either independently or via a stress-compliance or stress-arousal mechanism although stress was related to cortisol activity. Neither the direct effects of cortisol nor a cortisol …
The Rhetoric Of Science: A Case Study Of The Cold Fusion Controversy., David Lee Hatfield
The Rhetoric Of Science: A Case Study Of The Cold Fusion Controversy., David Lee Hatfield
LSU Historical Dissertations and Theses
This dissertation examines the circumstances surrounding and the rhetoric involved in the cold fusion controversy begun on March 23, 1989, when two University of Utah electrochemists, Martin Fleischmann and Stanley Pons, announced by press conference the discovery of room-temperature nuclear fusion. The dissertation seeks to determine to what extent a rhetorical analysis of cold fusion discourse may increase understanding of the controversy; the success of Fleischmann and Pons as scientific rhetors; the ways in which scientists' attitudes, values, and assumptions manifest themselves in the discourse; and finally, what may be learned about scientific discourse in general by examining the cold …
Making The Secular Sacred: An Analysis Of Linguistic Devices Used To Give Religious Perspective To Ordinary Events., Wayne Porter Gregory
Making The Secular Sacred: An Analysis Of Linguistic Devices Used To Give Religious Perspective To Ordinary Events., Wayne Porter Gregory
LSU Historical Dissertations and Theses
It has been suggested that human beings do not possess social reality so much as they actively and cooperatively construct it by means of language in interaction with others. The manipulation of symbols, the creation of inferences, the posturing of one's personal identity all work together to enable participants (both speakers and hearers) in a given speech event to create social reality and reaffirm and maintain their social relationships. In religious speech communities, like the one investigated in this study, participants seek to create a different kind of social reality--one that encompasses all of the individual and corporate experiences of …
Genetic And Systematic Study Of Viviparus Georgianus (Lea), A Freshwater Snail Species Complex., Masaya Katoh
Genetic And Systematic Study Of Viviparus Georgianus (Lea), A Freshwater Snail Species Complex., Masaya Katoh
LSU Historical Dissertations and Theses
Genetic and morphological variation were studied in a brooding (ovoviviparous) and morphologically variable freshwater snail (Viviparus georgianus (Lea)) in the southeastern United States. Eleven populations were clustered into three genetically isolated, allopatric species characterized by 7 to 15 diagnostic loci out of the 38 loci examined. These allopatric species were an eastern species (in eastern and southern Florida), a western species (in the Florida panhandle), and a central species in the Ochlockonee River. Nei's standard genetic distances between species were large (0.23-0.52) compared to within-species distances (0.00-0.06). Moreover, genetic distances between the Ochlockonee River species and other species were larger …
Recovery Of Sugars From Cane Molasses By Continuous Simulated Moving Bed Ion-Exclusion Chromatography., Khalid Iqbal
Recovery Of Sugars From Cane Molasses By Continuous Simulated Moving Bed Ion-Exclusion Chromatography., Khalid Iqbal
LSU Historical Dissertations and Theses
Present investigation was undertaken to determine the feasibility of using a Simulated Moving Bed (SMB) Ion Exclusion Chromatographic system for the recovery of sugars from molasses. The recovery of sugars from molasses is complicated because of the presence of high concentration of salts of K, Ca, Mg, etc. The presence of these salts in the molasses prevents sucrose to crystallize. SMB Ion Exclusion Chromatography has been shown to be successful to recover sugars from beet molasses, and to separate sugars from each other in High Fructose Corn Syrup industry. The basis of the ion exclusion is that the sorbent used …
Metaphor Within/Without Metaphysics: Nietzsche, Heidegger, And Derrida., Jonggab Kim
Metaphor Within/Without Metaphysics: Nietzsche, Heidegger, And Derrida., Jonggab Kim
LSU Historical Dissertations and Theses
The contemporary preoccupation with metaphor lies in its capability of deconstructing and disempowering metaphysics, and of creating a logic of uncertainty or a Derridian logic of supplements in opposition to the logic of identity and of non-contradiction. As a figure of speech saying one thing but meaning something else, metaphor contains in itself a certain alterity and otherness which resists a logical identity as well as a systematic philosophy. In my study of metaphor in the texts of Nietzsche, Heidegger, and Derrida, I inquire into the problematic relation or difference between philosophy and metaphor, focusing on how the former is …
Control Of Phytoplankton Production In A Shallow, Turbid Estuary., Christopher J. Madden
Control Of Phytoplankton Production In A Shallow, Turbid Estuary., Christopher J. Madden
LSU Historical Dissertations and Theses
Water column primary production and chlorophyll were sampled between 1986-1991 in Fourleague Bay, LA, a shallow (1.5 m), river-dominated estuary that is extremely turbid (K$\sb{\rm D}$ = 4.44 m$\sp{-1}$). A high speed system for continuous flow-through sampling, Dataflow$\sp\copyright$, was developed to measure physicochemical variables and in vivo chlorophyll fluorescence at high temporal (1 s) and spatial (5 m) resolution from a small boat. Phytoplankton net primary production (NPP) was measured using an incubator which rotated bottles to prevent settling of the contents. NPP was found to be artificially increased by 10-83% at high light levels in non-rotated bottles when cells …
Shoot Growth And Form Of Senna Obtusifolia In Response To Soybean And Intraspecific Competition., James Edward Smith
Shoot Growth And Form Of Senna Obtusifolia In Response To Soybean And Intraspecific Competition., James Edward Smith
LSU Historical Dissertations and Theses
Effects of competition on growth and formation of shoot structure in sicklepod (Senna obtusifolia) were examined, with particular emphasis on the effect of nearest neighbors on branching and canopy formation. Sicklepod was established as (1) stands of 26 plants m$\sp{-2}$ added to soybean, (2) individuals widely enough spaced to produce only interspecific competition when added to soybean, or (3) regularly spaced monoculture stands with 15, 25, 35, and 50 cm interplant distances. Repeated surveys of individual shoots characterized sicklepod growth and shoot structure in terms of position of and growth at each node. Sicklepod leaf area, internode elongation, node production, …
Community Versus The Imperial Mind: Images Of Civil Strife In Hawthorne's "The Marble Faun"., Henry Michael W Russell
Community Versus The Imperial Mind: Images Of Civil Strife In Hawthorne's "The Marble Faun"., Henry Michael W Russell
LSU Historical Dissertations and Theses
Nathaniel Hawthorne's The Marble Faun allegorically represents the crisis of civil order in the American Republic in the 1850s foreshadowing the Civil War that erupted a year after the novel's publication. Hawthorne's last completed romance, set in Rome, suggests Americans must judge themselves against the community and continuity embodied in the European culture they had recently cast off. Challenging Emerson's doctrine that man may have an original relationship to history and the Creator, Hawthorne undermines the Founders' great idea: that an assembly of men could discover and formulate--in an act of the human mind--self-evident, inalienable rights that govern political and …
Failure Predictions In Repairable Multi-Component Systems., Woodrow Thomas Roberts Jr
Failure Predictions In Repairable Multi-Component Systems., Woodrow Thomas Roberts Jr
LSU Historical Dissertations and Theses
The subject of this research is the prediction of failures in repairable multi-component systems from statistical models that utilize the historical failure data for the systems. Failures occurring in repairable systems are examples of a series of discrete events which occur randomly in a continuum. Such stochastic point processes are analyzed using the statistics of event series. The Crow nonhomogenous Poisson process, NHPP, model is recognized by the reliability community as being one of the best models for repairable systems. The objective of this research is to show that the Crow NHPP model, with its overall failure predictions for a …

Ultrafast Study Of Photochemistry On Chromium Hexacarbonyl Using Resonance Raman Spectroscopy., Soo-Chang Yu
LSU Historical Dissertations and Theses
In this dissertation ultrafast photochemistry of Cr(CO)$\sb6$ using picosecond resonance Raman spectroscopy is studied. The advantage of the transient resonance Raman spectroscopy for this study is demonstrated along with a Raman differencing technique. This study is divided into two main parts. The first part deals with the property of the electronic excited state of the Cr(CO)$\sb6.$ The attempt to reveal the excited electronic structure of Cr(CO)$\sb6$ is tried with the help of Albrecht vibronic theory and wave packet description. Reaction coordinate and Jahn-Teller effects have been investigated in detail. Two possible reaction coordinates are found in contrast to the results …
Stratigraphic Architecture Of An Extensional Orogen: The Mojave Extensional Belt, Southern California., Christopher John Travis
Stratigraphic Architecture Of An Extensional Orogen: The Mojave Extensional Belt, Southern California., Christopher John Travis
LSU Historical Dissertations and Theses
Field-based studies and quantitative models provide new insights into the stratigraphic architecture of a developing continental extensional orogen. The early Miocene age Mojave Extensional Belt of southern California (MEB) exhibits a tripartite stratigraphy, consisting of (1) pre- to early synextension volcanic deposits, unconformably overlain by (2) syntectonic basement-derived megabreccia and breccia with local finer-grained units, overlain by (3) a posttectonic fining-upward sequence of gravel, sand, shale, and limestone. On a more local scale, stratigraphy and sediment dispersal within the MEB reflect the evolution of the major tectonic elements of the belt: (1) Breakaway zone. Strata of the western Newberry Mountains …

Interactive Graphics-Based Musculotendon Modeling For Reconstructive Surgery Of The Hand., Inmo Yoon
LSU Historical Dissertations and Theses
This research has been directed at studying and developing a prototype research and clinical Computer Aided Design (CAD) tool to be used for planning tendon paths in hand reconstructive surgery. Of equal importance is the goal of having an educational tool for teaching hand biomechanics to students of this specialty. The application of CAD to rehabilitative surgery of the hand is a new field of endeavor. There are currently no existing commercial products designed to assist the orthopedic surgeon in planning these complex procedures. Additionally, orthopedic surgeons are not trained in mechanics, kinematics, math modeling, or the use of computers. …
Changing Patterns Of Centralization And Decentralization In American School Governance., Charles Walter Triche Iii
Changing Patterns Of Centralization And Decentralization In American School Governance., Charles Walter Triche Iii
LSU Historical Dissertations and Theses
This dissertation traces the evolution of American school governance and educational administration from the mid-seventeenth century through 1991. It examines the arguments which surround the centralization or decentralization debate and traces the rationale for the adoption of either a centralist or decentralist manner of school governance. In tracing the evolution of the rationale used by educational administrators for the adoption of either a centralist or decentralist form of governance, this dissertation establishes an order to the debate, traces shifts in philosophy, determines the dominance of either centralist or decentralist philosophy during each historical period studied, and identifies reasons why that …
Partisan Representational Form And Partisan Bias In United States State Lower-House Legislative Elections: A District-Level Approach., Kenneth Alan Wink
Partisan Representational Form And Partisan Bias In United States State Lower-House Legislative Elections: A District-Level Approach., Kenneth Alan Wink
LSU Historical Dissertations and Theses
I explore the relationship between partisan votes and partisan seat allocation in U.S. state lower-house elections. Specifically, I measure the representational form (the rate of partisan seat changes given particular partisan vote changes) and partisan bias (asymmetry in the seats-votes relationship) of 441 lower-house state legislative elections in 46 states from 1968 to 1987. I then test a number of hypotheses that have been advanced to explain variation in representational form and partisan bias. Values for representational form and partisan bias are generated by creating simulations from actual election results. I simulate seat gains made by Republicans given one percent …
From Their Perspective: Issues Of Schooling And Family Culture Of Four African-American First Generation College Students., Neari Francois Warner
From Their Perspective: Issues Of Schooling And Family Culture Of Four African-American First Generation College Students., Neari Francois Warner
LSU Historical Dissertations and Theses
The diversity of students entering today's colleges and universities makes it increasingly important that educators, theorists and other scholars strive toward a fuller understanding of the life conditions of minority groups. This research is designed to provide insight into the processes, pressures and people that shape the lives of one particular minority group, the African American non-traditional, first generation college student. In this research, I examine the school and family experiences of four of these students in an attempt (1) to provide data that contribute to the refutation of the stereotypical images and myths that are so pervasively used to …
Phylogenetic Systematics Of The Ulvophyceae (Chlorophyta) Based On Cladistic Analyses Of Ribosomal Rna Genes And Morphology., Frederick William Zechman
Phylogenetic Systematics Of The Ulvophyceae (Chlorophyta) Based On Cladistic Analyses Of Ribosomal Rna Genes And Morphology., Frederick William Zechman
LSU Historical Dissertations and Theses
Cladistic analyses of non-molecular and nuclear-encoded rRNA sequence data provided the basis for hypotheses of relationships for the green algal class Ulvophyceae. Non-molecular data rooted with Chara support hypotheses which group the Chlorophyceae and Pleurastrophyceae with ulotrichalean and ulvalean Ulvophyceae. Analyses of rRNA sequence data group the siphonous and siphonocladous Ulvophyceae (i.e. Caulerpales, Siphonocladales, and Dasycladales) with the Chlorophyceae and Pleurastrophyceae. Although hypotheses supported by these independent data sets are incongruent, they suggest that the Ulvophyceae is not monophyletic. Based on rRNA sequences, pleurastrophycean taxa, which, like the Ulvophyceae, possess a counter-clockwise arrangement of flagellar basal bodies, are more closely …
The Influence Of Job Satisfaction And Organizational Commitment On Intention To Leave Of Nurse Educators., Catherine Blackwell Holland
The Influence Of Job Satisfaction And Organizational Commitment On Intention To Leave Of Nurse Educators., Catherine Blackwell Holland
LSU Historical Dissertations and Theses
The purpose of this study was to determine what factors influenced the intention of nurse educators to leave their current teaching positions at the university level in Louisiana. A simple random sample of 125 nurse educators employed full time in baccalaureate degree nursing programs were the study subjects. Respondents were 115 (92%) of the nurse educators. A four part instrument was used for data collection and analysis: Job Descriptive Index (JDI) and Job In General (JIG), Organizational Commitment Questionnaire (OCQ), Intention to Leave (ITL), and demographic information. Intention to Leave was a researcher developed instrument to measure intention to leave. …
Molecular Cloning, Expression And Site-Directed Mutagenesis Of A Complementary Dna Encoding Rabbit Muscle Fructose 6-Phosphate-1-Kinase., Jau-Yi Li
LSU Historical Dissertations and Theses
This dissertation contains three parts based on my research project which investigates three aspects of rabbit muscle phosphofructokinase (ATP: D-fructose-6-phosphate-1-phosphotransferase, EC 2.7.1.11; PFK). The first part reports the isolation and characterization of two full-length rabbit muscle PFK cDNAs. The DNA sequences of these two cDNAs (cDNA-A and cDNA-B) show an identical coding sequence but heterogeneous 5$\sp\prime$untranslated regions. cDNA-A is formed by removal of a 1.7 Kb upstream intron while cDNA-B retains the 3$\sp\prime$region of this intron. The second part describes the expression of the cDNA in several bacterial hosts. Recombinant rabbit muscle PFK has been expressed at a significant level …
Applicability Of Bioluminescence Assay And Aerobic Bacterial Counts For The Evaluation Of Raw Milk Quality., Abdul Ghafoor Mian
Applicability Of Bioluminescence Assay And Aerobic Bacterial Counts For The Evaluation Of Raw Milk Quality., Abdul Ghafoor Mian
LSU Historical Dissertations and Theses
Raw milk samples were analyzed to determine the bacteriological quality by the standard plate count (SPC), adenosine-5$\sp\prime$-triphosphate (ATP) assay, preliminary incubation counts, and the psychrotrophic bacteria count (PBC). In a comparison of SPC and ATP content, an overall correlation coefficient of 0.97 was found between the two methods. The correlations between ATP content and SPC of fresh raw milk samples at zero hour and after preliminary incubating these samples at 12.8 and 15.6$\sp\circ$C for 18 hours were.96,.97, and.97, respectively. The regression coefficients for all types of milk samples were highly significant ($P <$.01). High correlation coefficients demonstrated that the ATP measurement in combination with preliminary incubation practices could be a rapid technique for the determination of bacteriological quality of milk at receiving stations and milk processing plants. Median SPC for 175 fresh raw milk samples was 36,000/ml. The bioluminescence technique is reported previously to have a good correlation with SPC in the range of 1.0 $\times$ 10$\sp5$ to 1.0 $\times$ 10$\sp{10}$ bacteria/ml. The commingled milk coming at the receiving stations sometimes have a bacterial count that is less than 1.0 $\times$ 10$\sp{5}$ bacteria/ml. A correlation coefficient of.87 was calculated between the SPC and ATP values for the overall data while lowering the SPC range from 1.0 $\times$ 10$\sp5$ to 1.0 $\times$ 10$\sp4$ bacteria/ml. This range is more practical as a quick screening of raw milk at dairy processing facilities since 81 percent of all raw milk samples fell in this range. An equation (SPC = $-$1642213 + 6751(ATP)) was developed from the combined experimental data which could estimate the SPC of raw milk samples using their ATP content. Another phase of the experiment was to ascertain if the Petrifilm$\sp{\rm TM}$ technique could be effectively used in place of agar method to estimate PBC. The correlation coefficient between the Petrifilm$\sp{\rm TM}$ and the agar plate method for both the fresh and preliminary incubated raw milk samples was.99. A high linearity of relationship shows that one method can be substituted with the other. However, the Petrifilm$\sp{\rm TM}$ technique took longer than the usual time of 25 h to develop red colonies at 21$\sp\circ$C because of the slow reduction of the dye reagent triphenyl tetrazolium chloride (TTC) at this temperature.
Shell-Model Description Of Rotational Motion In Odd-Mass Nuclei., Husney Ahmed Naqvi
Shell-Model Description Of Rotational Motion In Odd-Mass Nuclei., Husney Ahmed Naqvi
LSU Historical Dissertations and Theses
An algebraic shell-model realization of a quantum rotor for integral and half-integral angular momenta is introduced. The underlying symmetry of the theory is the SU(3) $\supset$ SO(3) group structure. The algebraic model reproduces the eigenvalues of the quantum rotor hamiltonian well for normal shell-model configurations; the mapping is exact for small values of the angular momentum in large SU(3) representations. A shell-model hamiltonian using this algebraic realization of the quantum rotor and other non-central one-body interactions is used to reproduce the experimental spectra of representative even and odd-mass ds-shell nuclei.
Perceptual Evaluation Of Infant Articulatory Transitions., Nancye Chaney Roussel
Perceptual Evaluation Of Infant Articulatory Transitions., Nancye Chaney Roussel
LSU Historical Dissertations and Theses
The transition portion of the speech signal has been identified as critical to the perception of both consonants and vowels. Furui (1986) demonstrated that for adult Japanese speakers a 10 ms segment of the transition centered on the area of maximum spectral movement contained the most critical information for joint consonant and vowel perception. The distribution of phonemic cues contained within consonant-vowel (CV) non-reduplicated (NRB) syllables of infants ages 6 months to 15 months was compared to the distribution observed in adult productions to examine the extent of coproductive overlap of infant consonant and vowel gestures. Truncated versions of infant …
