Functional Morphology Of The Lingual Apparatus Of Sandgrouse (Aves: Pteroclidae)., Werner Muller Jan 1993

Functional Morphology Of The Lingual Apparatus Of Sandgrouse (Aves: Pteroclidae)., Werner Muller

LSU Historical Dissertations and Theses

The morphology of the lingual apparatus of three species of sandgrouse (Aves; Pteroclidae) has been described. All biomechanically important parts were included in the description, i.e., all muscles potentially involved in the functioning of the lingual apparatus, all skeletal parts, the salivary glands associated with the lingual apparatus, and the surface morphology of the oropharyngeal cavity. For each muscle its potential functions have been described. In a comparison with data from the literature of three other groups of birds it was found that the functional organization of the lingual apparatus of the sandgrouse is strikingly similar to the one found …

Differential Comparison Standards And Their Subsequent Effects On The Agreement Between Self- And Supervisor Performance Appraisal Ratings., Brian Wayne Schrader Jan 1993

Differential Comparison Standards And Their Subsequent Effects On The Agreement Between Self- And Supervisor Performance Appraisal Ratings., Brian Wayne Schrader

LSU Historical Dissertations and Theses

This study examined differential comparison standards (i.e., comparative bases for performance evaluation) and their effects on the level of agreement between supervisory and self-raters (i.e., subordinates) within the context of a performance appraisal system. The purpose of the research was to determine whether differential comparison standards represented an underlying mechanism in the traditionally poor correlational relationship between self-supervisor performance ratings. Supervisor and subordinate rater dyads (N = 106 dyads) evaluated job performance across three dimensions using five different comparison standards (ambiguous, internal, absolute, relative, and multiple) in addition to providing preference, availability, and relevancy ratings. Results supported the hypotheses indicating …

A Policy Approach To Educational Leadership In The State Legislature., Sue Wells Weaver Jan 1993

A Policy Approach To Educational Leadership In The State Legislature., Sue Wells Weaver

LSU Historical Dissertations and Theses

This study investigated legislative expert influence in the context of educational policy decisions. Institutional and behavioral approaches to legislative study were compared. In a chi square analysis of all legislative education enrollments in the 1993 Regular Session of the Louisiana Legislature, legislation introduction success was positively associated with author's level of credential and reputation expertise. Relative importance of type of expertise was indeterminable and some influence was unaccountable in the analysis. The policy approach, based on Theodore Lowi's theory that policy predicts politics, integrated the prior approaches. Lowi's distributive-regulatory-redistributive schema informed the independent policy variables, while influence, role, and subsystem …

The Antecedents And Consequences Of Transformational Leadership., Andrew J. Meibaum Iii Jan 1993

The Antecedents And Consequences Of Transformational Leadership., Andrew J. Meibaum Iii

LSU Historical Dissertations and Theses

The present study examined the relations among theoretical antecedents and consequences of transformational leadership style. Thirty hospital CEOs completed questionnaires measuring self-esteem, autonomy, need for achievement, dominance, and hospital strategy. In addition, 214 subordinates rated the leadership style of the 30 CEOs. The hypothesized links between CEO personality and transformational leadership style were not supported. Also, the hypothesized relation between transformational leadership style and organizational effectiveness was not supported. Supplemental analyses revealed a direct relation between CEO self-esteem and organizational effectiveness and between organizational strategy and organizational effectiveness. Specifically, CEO self-esteem was positively related to organizational effectiveness, and a domain-offensive …

Embedding Schemes For Interconnection Networks., David Aloys Hoelzeman Jan 1993

Embedding Schemes For Interconnection Networks., David Aloys Hoelzeman

LSU Historical Dissertations and Theses

Graph embeddings play an important role in interconnection network and VLSI design. Designing efficient embedding strategies for simulating one network by another and determining the number of layers required to build a VLSI chip are just two of the many areas in which graph embeddings are used. In the area of network simulation we develop efficient, small dilation embeddings of a butterfly network into a different size and/or type of butterfly network. The genus of a graph gives an indication of how many layers are required to build a circuit. We have determined the exact genus for the permutation network …

Hydrogeochemistry Of Saline Waters In Aquifers Of Tertiary And Younger Age In Northeastern Louisiana And Southeastern Arkansas., Glenn Fredrick Huff Jan 1993

Hydrogeochemistry Of Saline Waters In Aquifers Of Tertiary And Younger Age In Northeastern Louisiana And Southeastern Arkansas., Glenn Fredrick Huff

LSU Historical Dissertations and Theses

Solute source tracing using Br/Cl and $\rm\sp{87}Sr/\sp{86}Sr$ ratios indicate that the source of brackish water in the Mississippi River alluvial and Jasper aquifers of Concordia Parish, Louisiana are brines and saline waters from the Wilcox aquifer. The proximity of maximum concentrations of dissolved solids to the location of plugged and abandoned oil wells and test holes indicates that brines and saline waters have migrated upward through these oil wells and test holes. Br/Cl ratios in the Wilcox aquifer suggest dissolution of halite as a major source of dissolved solids. Apparent thermodynamic equilibrium exists between plagioclase and kaolinite, plagioclase and Na-smectite, …

Recognition And Production Of Facial Emotion By Autistic Children., Steven R. Love Jan 1993

Recognition And Production Of Facial Emotion By Autistic Children., Steven R. Love

LSU Historical Dissertations and Theses

Autistic males ages 8 to 16 made significantly more errors than did chronologically and intellectually age-matched nonautistic normal and mentally retarded males on emotion recognition tasks using audiotaped and videotaped emotion sequences. The audiotape and videotape included "happy" "sad," "scared," "angry," and "no emotion" sequences. Emotional sequences included emotionally relevant verbal content and the length of verbalized material in the emotional sequences was limited to between 4 and 10 words. Videotaped sequences showed actors portraying facial expressions and verbal content consistent with the five emotion states. Both tapes were rated by normal adults and children as containing "socially valid" representations …

Contributions Of Monoclonal Antibodies With Anti-Neural Cell Adhesion Molecule Like Activity To Peripheral Nerve Regeneration., Laura G. Remsen Jan 1993

Contributions Of Monoclonal Antibodies With Anti-Neural Cell Adhesion Molecule Like Activity To Peripheral Nerve Regeneration., Laura G. Remsen

LSU Historical Dissertations and Theses

Tubes containing monoclonal antibodies with anti-neural cell adhesion molecule (N-CAM)-like activity were applied to transected sciatic nerves to attempt to perturb the recovery of muscle function. Physiological recordings were used to estimate the return of function. The decline of implanted antibody over 28 days was estimated. No significant immune responses were detected in response to the implanted material. Electron microscopic and immunohistological analyses evaluated particular cellular disruptions in nerves due to the presence of these antibodies with anti-N-CAM like activity. Histological sections of fixed experimental nerves consistently revealed abnormal gaps between Schwann cells of regenerating nerves. This specific Schwann cell …

A Performance-Centered Approach To Leslie Marmon Silko's "Ceremony"., Randall Thomas Hill Jan 1993

A Performance-Centered Approach To Leslie Marmon Silko's "Ceremony"., Randall Thomas Hill

LSU Historical Dissertations and Theses

This study argues that in Ceremony Leslie Marmon Silko rehearses her Laguna-Keres culture and her culture's interactions with others. She accomplishes this rehearsal by employing representations of performances from the Laguna people as well as other cultures. To establish the context of my argument, first I offer a brief exploration of the current critical interest in Native American arts and cultures, review questions involved in defining the parameters for a study of Native American novels, examine the significance of Native novels for performance scholarship, and review performance studies scholars' responses to Native texts. Second, I review methodologies from a variety …

Highly Resolved Studies Of Vacuum Ultraviolet Photoionization Dynamics., Sandeep Kakar Jan 1993

Highly Resolved Studies Of Vacuum Ultraviolet Photoionization Dynamics., Sandeep Kakar

LSU Historical Dissertations and Theses

We use measurements of dispersed fluorescence from electronically excited photoions to study fundamental aspects of intramolecular dynamics. Our experimental innovations make it possible to obtain highly resolved photoionization data that offer qualitative insights into molecular scattering. In particular, we obtain vibrationally resolved data to probe coupling between the electronic and nuclear degrees of freedom by studying the distribution of vibrational energy among photoions. Vibrationally resolved branching ratios are measured over a broad spectral range of excitation energy and their non-Franck-Condon behavior is used as a tool to investigate two diverse aspects of shape resonant photoionization. First, vibrational branching ratios are …

A Restoration-Based Model For Materials Management In A Global Manufacturing Environment., Gary Wayne Clendenen

LSU Historical Dissertations and Theses

Globalization of manufacturing along with increased competition has made effective planning and control more important than ever. At the same time, it is more difficult than ever to achieve effective planning and control due to larger leadtimes and shorter product life cycles. The objective of this research is to explore the importance of control strategy on materials management in global manufacturing networks. Control strategies in common use and others that have recently been proposed in the literature are reviewed and classified along a push/pull gradient. It is shown that one of them, the restoration control strategy, can be used to …

An Examination Of The Spontaneously Generated And Retold Narratives Produced By Gifted/Learning-Disabled Adolescents From An Integrated Perspective Of Language Development., Phebe Archon Hayes

LSU Historical Dissertations and Theses

Few studies have examined the narrative abilities of gifted children with learning disabilities. This study investigated the ability of eighth-grade gifted children with learning disabilities (gifted/LD) to produce oral and written narratives by comparing their stories to those produced by gifted peers with no learning deficits (nonLD/gifted). It was hypothesized that evidence of difficulty generating the stories relative to the macrostructure (organization of ideas across sentences) and the microstructure (organization of ideas within sentences) would be exhibited by the gifted/LD population. Twenty, 13-year-old eighth-graders served as subjects in the present investigation. All were identified as gifted by their local school …

Factors Affecting The Time-Course Of Auditory Stream Segregation., Lawrence Lee Mendoza Iii Jan 1993

Factors Affecting The Time-Course Of Auditory Stream Segregation., Lawrence Lee Mendoza Iii

LSU Historical Dissertations and Theses

Auditory scene analysis refers to the process through which sounds are heard as either belonging to separate sources or as perceptually grouped together and arising from a single source. Stream segregation describes the perceptual separation of sounds, while sequential integration is a term used to describe the linking together of sounds following one another in time. This study examined the minimum duration necessary for the perception of sequentially-presented sounds to change from sequential integration to stream segregation. The experimental stimuli were sequences of alternating sounds. Auditory scene analysis was examined under conditions in which the sequential sounds differed only in …

Predicting The Movement And Retention Of Pesticides In Soils: Physical And Chemical Nonequilibrium Modeling Approaches., Liwang Ma Jan 1993

Predicting The Movement And Retention Of Pesticides In Soils: Physical And Chemical Nonequilibrium Modeling Approaches., Liwang Ma

LSU Historical Dissertations and Theses

Atrazine retention and transport in a highly aggregated Sharkey clay soil were investigated through kinetic batch experiments, miscible displacement (column transport), and mathematical modeling. Batch results indicated that atrazine retention was kinetic and adsorption-desorption was hysteretic. Adsorption and desorption isotherms were well described using the Freundlich equation (S = KC$\sp{\rm N}).$ Fitted Freundlich K was a function of reaction time and initial atrazine input concentrations, whereas fitted N was only affected by reaction time. Desorption hysteresis was quantified by the maximum difference between adsorption and desorption isotherms, and showed a linear increase with reaction time. Atrazine adsorption kinetics was successfully …

Mathematics And Gender: A General History Of Recent Research And Common Perceptions., Mary E. Reeves Jan 1993

Mathematics And Gender: A General History Of Recent Research And Common Perceptions., Mary E. Reeves

LSU Historical Dissertations and Theses

In the last two decades a tremendous volume of research data has been collected about differences between female and male students in mathematics. But although the amount of data collected has been large, there have been few conscious attempts to understand this data in social, economic, technological, and political terms. This history of academic research on gender differences connects the explosion of academic interest in the 1970s and 1980s with the launch of Sputnik in 1957 and the sense of technological crisis that pervades mathematics education and popular consciousness. The emergence of "Women's Lib" and interest in gender equity in …

Neo-Hamiltonian Republicans And Military Reform In The Progressive Era: 1898-1912., Ronald James Barr Jan 1993

Neo-Hamiltonian Republicans And Military Reform In The Progressive Era: 1898-1912., Ronald James Barr

LSU Historical Dissertations and Theses

The Spanish-American War changed the course of American history. In a few months the United States acquired a colonial empire and adopted a policy of overseas involvement that greatly altered future world events. The political victory of a few military reformers and politicians, who endorsed Social Darwinism, over those who upheld the ideas of Jefferson and Jackson, destroyed the international isolation of the American republic. No matter what successive political administrations claimed, they inherited substantial overseas commitments. The group that engineered this profound change in American foreign and defence policy were led by Elihu Root, John Hay, Leonard Wood, Alfred …

Boardinghouses, Parties And The Creation Of A Political Society: Washington City, 1800-1830, Cynthia Diane Earman Nov 1992

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 …

Multiplication, Division, And Shift Instructions In Parallel Random Access Machines, Jerry L. Trahan, Michael C. Loui, Vijaya Ramachandran Jun 1992

Multiplication, Division, And Shift Instructions In Parallel Random Access Machines, Jerry L. Trahan, Michael C. Loui, Vijaya Ramachandran

Faculty Publications

We prove that polynomial time on a parallel random access machine (PRAM) with unit-cost multiplication and division or on a PRAM with unit-cost shifts is equivalent to polynomial space on a Turing machine (PSPACE). This extends the result that polynomial time on a basic PRAM is equivalent to PSPACE to hold when the PRAM is allowed multiplication or division or unrestricted shifts. It also extends to the PRAM the results that polynomial time on a random access machine (RAM) with multiplication is equivalent to PSPACE and that polynomial time on a RAM with shifts (that is, a vector machine) is …

Nietzsche And Heraclitus, Virginia Lyle Jennings Howard Apr 1992

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, …
