Spinach Carbonic Anhydrase: Primary Sequence, Transport Into Chloroplasts And Expression In Escherichia Coli., Timothy William Fawcett Jan 1990

Spinach Carbonic Anhydrase: Primary Sequence, Transport Into Chloroplasts And Expression In Escherichia Coli., Timothy William Fawcett

LSU Historical Dissertations and Theses

Carbonic anhydrase (CA) catalyzes the reversible hydration of CO$\sb2$. Plant carbonic anhydrases are structurally distinct from those found in animals. In C$\sb3$ plants, the enzyme is located in chloroplasts. To date, little structural information on the enzyme from plants has been available. In this study the full-length cDNA for the spinach chloroplast CA was sequenced. The cDNA contained 1,156 base pairs. The open reading frame encoded a protein of 34,569 daltons. Comparison of the N-terminal sequence of this protein with that of other chloroplast precursors indicated that CA is synthesized as a precursor. The transit peptide likely contains about 60 …

Biased Estimation In The Context Of The Hedonic Pricing Model For Housing., John Ross Knight Jan 1990

Biased Estimation In The Context Of The Hedonic Pricing Model For Housing., John Ross Knight

LSU Historical Dissertations and Theses

This dissertation compares eight biased estimators as alternatives to Ordinary Least Squares estimation in the context of predicting residential real estate prices. It considers ridge rule estimation and principal components regressions, techniques that have previously been proposed for this application. It also introduces the use of Stein-like rules for predicting housing prices. The study examines relative performance of these estimators in three data settings and under four separate assumptions regarding loss criteria. The first test of the estimators uses Multiple Listing Service (MLS) data for Baton Rouge, Louisiana between 1984 and 1989 to examine relative predictive effectiveness in a time …

An Exploration Of The "Paradoxical" View Of Coupling Structure And School Effectiveness., Connie Stokes Logan Jan 1990

An Exploration Of The "Paradoxical" View Of Coupling Structure And School Effectiveness., Connie Stokes Logan

LSU Historical Dissertations and Theses

The purpose of this study was to utilize the organizational perspective of coupling to extend our understanding of effective schools as complex social systems. Part One of the study focused on the continued development and refinement of the Organizational Coupling Structure Inventory-Teacher Form (OCSI-T) to measure coupling structure in schools (Logan & Ellett, 1989). Part Two of the study focused on the examination of key research questions that bear on understanding the coupling construct and school effectiveness. The findings from Part One of the study support the OCSI-T as a reasonably valid and reliable inventory for measuring five dimensions of …

Narrative And Everyday Experience: Performance Process In The Storytelling Of The Swiss Volhynian Mennonites. (Volumes I And Ii)., John Elmer Mccabe-Juhnke Jan 1990

Narrative And Everyday Experience: Performance Process In The Storytelling Of The Swiss Volhynian Mennonites. (Volumes I And Ii)., John Elmer Mccabe-Juhnke

LSU Historical Dissertations and Theses

This study examines oral narrative performance within the cultural context of the Swiss Volhynian Mennonites in Moundridge, Kansas, whose forebears were members of a congregational group that migrated from the Russian Province of Volhynia in 1874. These immigrants strove to maintain Gemeinde--a mutually supportive community of believers separated from the world. A Swiss Volhynian Mennonite himself, the author tape-recorded interviews with second and third generation descendants of the Russian immigrants. Using the interview transcriptions and personal observation in the Moundridge community as primary data, the author demonstrates how the formative elements of everyday narrative performance both sustain and are shaped …

Designing Efficient Algorithms For Distributed Systems., Mohan B. Sharma Jan 1990

Designing Efficient Algorithms For Distributed Systems., Mohan B. Sharma

LSU Historical Dissertations and Theses

Search for efficient algorithms for distributed systems has become an important area of computer science. This research is driven by the need to efficiently process and communicate information generated by the system. In distributed systems, topological information plays an important role in the design of fast algorithms for problems such as routing, broadcasting, and sorting. The central focus of this dissertation is the design and analysis of distributed algorithms for determining topological information in asynchronous communication networks. Specifically, we present distributed algorithms for two generic problems: distributed graph problems and network traversal problems. Network location and network recognition are two …

The Role Of Sonority In Jargonaphasia., Sarah Slack Christman Jan 1990

The Role Of Sonority In Jargonaphasia., Sarah Slack Christman

LSU Historical Dissertations and Theses

The Sonority Sequencing Principle suggests that the relative sonority rank among sounds can explain intrasyllabic and transsyllabic phoneme ordering patterns in normal speakers. The values of segments can be ranked from most to least sonority as follows: Vowels, Glides, Liquids, Nasals and Obstruents. The unmarked order of segments within an initial demisyllable is O-N-L-G from the periphery toward the peak, and G-L-N-O in a final demisyllable from the peak toward the periphery. The sonority "slope" of an initial demisyllable will be steep to maximize the perceptual saliency of syllable onset. In a final demisyllable, especially if embedded, the slope will …

The Relationship Between Family Communication And Psychosocial Adjustment Of Cancer Patients., James Micheal Gotcher Jan 1990

The Relationship Between Family Communication And Psychosocial Adjustment Of Cancer Patients., James Micheal Gotcher

LSU Historical Dissertations and Theses

The purpose of this study was to examine the relationship between patient-family communication and psychosocial adjustment to cancer. Cancer patients receiving radiation therapy (n = 105) were interviewed using a semi-structured format. The majority of female subjects were being treated for breast cancer and the majority of male subjects for prostate cancer. Questionnaires assessing psychosocial adjustment and patient-family communication were employed. Psychosocial adjustment was tapped by means of the Psychosocial Adjustment to Illness Scale (PAIS). The PAIS provides a global adjustment score and taps seven independent domains of adjustment: health care orientation, vocational environment, domestic environment, sexual relations, extended family …

Usage-Dependent Information Systems Design., Jin-Soo Kim Jan 1990

Usage-Dependent Information Systems Design., Jin-Soo Kim

LSU Historical Dissertations and Theses

Usage-dependent phenomenon has been commonly observed in computer information systems (CIS). Since the performance of CIS greatly depends on the phenomenon, how to model it is an important CIS design issue. A usage process model (the Simon-Yule model) for modeling the usage--dependent phenomenon is proposed. The model is modified and successfully applied to the performance evaluation of self-organizing linear search heuristics. Analytical and empirical results indicate that the model provides a realistic performance evaluation of the heuristics and presents a solution to the research open problems which have been unsolved for more than two decades. Furthermore, the results lead to …

Attributions Of Teachers And Students In Middle School Science Classrooms., Lennie Holomon Rhys Jan 1990

Attributions Of Teachers And Students In Middle School Science Classrooms., Lennie Holomon Rhys

LSU Historical Dissertations and Theses

The purpose of the present study was to examine: (a) teachers' notions about their students, (b) students' notions about themselves and learning, and (c) important factors that characterize, and possibly influence, these notions. The investigation was based on attribution theory, which proposes a framework for ascribing causes of a person's behavior, given that person's belief system. In this study, five notions, or attributions, were specified: attachment, concern, satisfied, indifferent, and rejection, and were expressed in three forms: oral, written, and behavioral. Subjects included three sixth-grade science teachers, three eighth-grade science teachers, and one science class from each teacher's schedule. For …

Stress Begins In Kindergarten: A Look At Behavior During Standardized Testing., Pamela Owen Fleege

LSU Historical Dissertations and Theses

Children's behavior during standardized achievement testing was explored through a qualitative study of two kindergarten classrooms. The subjects were 36 kindergarten children (10 Black, 26 white; 17 males, 19 females). Data were collected through observations in the classrooms; interviews with children, teachers, and principals; and video taping of the children before, during, and after standardized achievement testing. Findings indicated an increase in behaviors reported to be stress related during the testing situation and a decrease in those behaviors following the testing period. Other frequently observed behaviors included copying and calling out answers during the administration of the test. In addition, …

A Rhetorical Analysis Of The Scientific-Romantic Synthesis In The Popular Scientific Writings Of Lewis Thomas., Donald Paul Lee Jan 1990

A Rhetorical Analysis Of The Scientific-Romantic Synthesis In The Popular Scientific Writings Of Lewis Thomas., Donald Paul Lee

LSU Historical Dissertations and Theses

As physician, educator, former medical administrator, and member of the National Academy of Sciences, Lewis Thomas has been one of the most eloquent spokespersons for the scientific community. This dissertation analyzes twenty-four of Thomas' popular scientific essays. These essays reveal a union of traditional scientific values and popular romantic themes, what is called here a rhetorical synthesis. The term synthesis is understood as the putting of two or more things together to form a whole, particularly suggesting a reconciliation of two philosophically opposing forces. Thomas' essays reflect a synthesis insofar as they merge what have traditionally been thought to be …

Epitope Mapping Of The Monoclonal Antibody Fac2 On The Apoprotein Of Cpa-1 In Photosystem Ii, Laurie K. Frankel, Terry M. Bricker Nov 1989

Epitope Mapping Of The Monoclonal Antibody Fac2 On The Apoprotein Of Cpa-1 In Photosystem Ii, Laurie K. Frankel, Terry M. Bricker

Faculty Publications

Using a combination of cyanogen bromide cleavage and endoproteinase digestion we have shown that the putative epitope for the monoclonal antibody FAC2 lies in the region 360Pro-391Ser on the apoprotein of CPa-1. This region lies entirely within the large extrinsic loop of this protein. We have shown previously that the epitope of FAC2 becomes exposed in oxygen-evolving membranes upon treatment with alkaline Tris which releases all four of the manganese associated with the oxygen-evolving site of photosystem II. The epitope is not exposed, however, after CaCl2 treatment and exposure to low concentrations of chloride, conditions which lead to the release …

Musical Theory And Practice In The Stage, Film, And Non-Theatre Collaborative Works Of Bertolt Brecht And Hanns Eisler, 1930-1956, Philip Lee Craik May 1989

Musical Theory And Practice In The Stage, Film, And Non-Theatre Collaborative Works Of Bertolt Brecht And Hanns Eisler, 1930-1956, Philip Lee Craik

LSU Historical Dissertations and Theses

The collaborative works of Bertolt Brecht and Hanns Eisler are based on a conscious aesthetic rising out of the application of the principles of dialectical materialism to all aspects of dramatic writing, musical composition, and theatre production. Although Brecht had definite opinions about the use of music in his own epic theatre productions, it was not until he met Eisler that he discovered a philosophical basis for those opinions in the writings of Hegel and Marx. The early collaborative work of these two was shaped by their association with the German Workers' Music Movement which took an active part in …

Effects Of Communicative Reading Strategies On The Literacy Behaviors Of Third-Grade Poor Readers., Sue Neames Hernandez Jan 1989

Effects Of Communicative Reading Strategies On The Literacy Behaviors Of Third-Grade Poor Readers., Sue Neames Hernandez

LSU Historical Dissertations and Theses

The purpose of this study was to examine the effects of Communicative Reading Strategies, an integrated approach to remedial reading instruction, on the reading, writing, and oral language proficiency of poor readers. Twenty eight third graders with poor reading and language abilities were randomly assigned to experimental and control groups. Communicative Reading Strategies (CRS) were employed with the experimental group. CRS treats reading as an integrated language process. Techniques were used such as: (1) providing orienting information, (2) clarifying the author's intention, (3) reducing the linguistic complexity of the text, (4) reiterating and conjoining ideas into complex propositions, and (5) …

A Knowledge-Based System For Message Translation. (Volumes I And Ii)., John Mark Usher Jan 1989

A Knowledge-Based System For Message Translation. (Volumes I And Ii)., John Mark Usher

LSU Historical Dissertations and Theses

This research addresses the use of a knowledge-based interface to provide the communication service of message translation. The focus of this research is on the technical feasibility of using a knowledge-based design to perform this service for programmable devices on the shop-floor. The uniqueness of this approach is in the use of a knowledge-based design for the software interface. This method of implementation is different from the procedural programming approach used in today's custom interfaces. This research asserts that use of a knowledge-based design will result in an interface system that is easier to construct and maintain than an interface …

Characterization And Potential Applications Of Cascade Arborols And Preparation Of Metallocyclic Palladium(Ii) And Rhodium(Iii) Complexes., Gregory Rufus Baker Jan 1989

Characterization And Potential Applications Of Cascade Arborols And Preparation Of Metallocyclic Palladium(Ii) And Rhodium(Iii) Complexes., Gregory Rufus Baker

LSU Historical Dissertations and Theses

A new class of specifically shaped, highly branched molecules was prepared where the branches emanate from tetrahedral carbons. This class of molecules has been named arborols because of their topological similarity to the "Leeuwenberg" model for tropical trees. The arborols were synthesized a layer (or tier) at a time to generate cascade spheres, where the number of terminal groups per sphere increases exponentially. Initially, molecules possessing a single cascade sphere attached to simple hydrocarbon chains were prepared to develop synthetic methods and provide proof-of-concept. Several series of dumbbell shaped, two-directional arborols were prepared, where two cascade spheres are connected via …

A Training Intervention For Control Of Sba Loan Defaults: A Theory Development Approach., J. Dennis Coates Jan 1989

A Training Intervention For Control Of Sba Loan Defaults: A Theory Development Approach., J. Dennis Coates

LSU Historical Dissertations and Theses

Since the energy-crisis days of the early 1970's, the United States' economy has been gradually moving from reliance on manufacturing operations to a reliance on service industries. This shift has lead to an abundance of opportunities in the area of small business development. In response to these opportunities, the small business sector has undergone substantial growth. One problem associated with this growth is the procurement of financing for small business startups. Since most entrepreneurs do not have the financing options available to large corporations, the majority of small business startups involve owner bank borrowing, often with the assistance of the …

Prospect Theory In Governmental Accounting: Implications For The Budgeting Process At The Local Level., Karen Sue Mckenzie Jan 1989

Prospect Theory In Governmental Accounting: Implications For The Budgeting Process At The Local Level., Karen Sue Mckenzie

LSU Historical Dissertations and Theses

Small local governmental units are responsible for allocating resources on behalf of a substantial portion of all United States citizens. The research reported here investigates the effects of presentation format (or framing) on decision preference in a governmental resource allocation context. The subjects represent a population of governmental units which has not received prior research attention--small local governments. Budget preparers were asked to choose among objectively identical alternatives, which differed in presentation formats. The cases used to investigate the effects of presentation were modelled after Kahneman and Tversky's (1979) seminal work in prospect theory, which addressed violations of expected utility …

Phonological And Language Improvements In Preschool Children: A Comparison Of Phonological Process Targeting And Whole Language Training., Joann Monjure Jan 1989

Phonological And Language Improvements In Preschool Children: A Comparison Of Phonological Process Targeting And Whole Language Training., Joann Monjure

LSU Historical Dissertations and Theses

This study compared phonological and language changes that occurred in preschool phonologically-impaired children following treatment via a discrete phonological process targeting approach or a whole language approach. It was hypothesized that a treatment program utilizing a communication-based, whole language approach would result in improvements in various language domains (e.g., phonology, morphology, syntax, semantics, and pragmatics), while treatment targeting a specific aspect of language, that is, phonology, would result in improvements limited to that specific domain. Subjects were eight preschool children, 3-4 years of age, exhibiting multiple articulation errors, and randomly assigned to one of two intervention programs for a six-week …

A Program Visualization System That Supports The Program Understanding Process., Brady R. Rimes

LSU Historical Dissertations and Theses

The goal of this research is to provide a graphical system that supports the program understanding process by representing the program's control flow, the code and the identifiers local to a specific point within the program. By having more information local to the point of interest, the programmer can maintain continuity in developing program understanding. The programmer can see loops, procedure calls, and other structures with respect to their execution order and can view them in the environment or the context in which they will execute. The Peec system supplies a graphical representation of the program's control flow in which …

Arch: A Robust Construction Heuristic For The Layout Design Of Food Processing Facilities., George Robert Baskin Jan 1989

Arch: A Robust Construction Heuristic For The Layout Design Of Food Processing Facilities., George Robert Baskin

LSU Historical Dissertations and Theses

A Robust Construction Heuristic (ARCH) represents the first attempt to develop a facilities layout design algorithm tailored to the particular solution of the food processing facility layout problem where a fluctuating product mix due to seasonality or changes in consumer demand is typical. The foundation literature for this research comes predominantly from the industrial engineering, management science, and food science fields. Construction heuristics built layouts from scratch and provided poor quality results. Robustness algorithms had no simplifying heuristics but were reported to yield potentially higher quality layouts than traditional algorithms for layout problems with fluctuating product mixes. ARCH was developed …

The Structural And Functional Roles Of Critical Amino Acid Residues In Drosophila Alcohol Dehydrogenase., Zhuo Chen Jan 1989

The Structural And Functional Roles Of Critical Amino Acid Residues In Drosophila Alcohol Dehydrogenase., Zhuo Chen

LSU Historical Dissertations and Theses

Alcohol dehydrogenase (ADH, alcohol:NAD oxidoreductase, EC1.1.1.1) from Drosophila melanogaster (DmADH) is unique among alcohol dehydrogenases in metal ion requirement, substrate preference, and stereospecificity of hydride transfer. In order to study this unique enzyme, the first part of this dissertation reports the construction and expression of DmADH cDNA in E. coli hosts. The second part of the dissertation shows the structural function of glycine-14 in putative NAD-binding domain of DmADH. The comparison of DmADH to horse liver ADH suggests that glycine-14 in DmADH is located at the first position of a "conserved sequence" which maintains the tight turn structure positioned in …
