Traffic Management And Congestion Control In The Atm Network Model., Sundararajan Vedantham Jan 1997

Traffic Management And Congestion Control In The Atm Network Model., Sundararajan Vedantham

LSU Historical Dissertations and Theses

Asynchronous Transfer Mode (ATM) networking technology has been chosen by the International Telegraph and Telephony Consultative Committee (CCITT) for use on future local as well as wide area networks to handle traffic types of a wide range. It is a cell based network architecture that resembles circuit switched networks, providing Quality of Service (QoS) guarantees not normally found on data networks. Although the specifications for the architecture have been continuously evolving, traffic congestion management techniques for ATM networks have not been very well defined yet. This thesis studies the traffic management problem in detail, provides some theoretical understanding and presents …

The Myth Of Narcissus And The Narcissistic Structure., Joachim Conrad Hermann Vogeler Jan 1997

The Myth Of Narcissus And The Narcissistic Structure., Joachim Conrad Hermann Vogeler

LSU Historical Dissertations and Theses

Since Freud's article "On Narcissism," behavioral psychologists have predominantly viewed this phenomenon as a personality disorder. This dissertation, in contrast, provides a psychoanalytic, i.e., Lacanian reading of the myth of Narcissus as it is recorded in classical literature, and brings about an understanding of the myth's underlying structure. The four fundamental exigencies of the myth's structure include the incest prohibition which symbolically castrates the human subject, the incestuous desire as a result of this prohibition, the displacement of this desire for another imaginary object, and the obsessive quest of that image as the symptom. This structure--defined as narcissistic structure and …

Rickettsia Felis, A Newly Discovered Rickettsia Associated With The Cat Flea (Ctenocephalides Felis Bouche)., Jimmy Wedincamp Jr

LSU Historical Dissertations and Theses

A study was performed to determine the life cycle of Rickettsia felis, a novel bacterium associated with cat fleas (Ctenocephalides felis Bouche). Cat flea populations maintain R. felis in successive generations by efficient transovarial transmission. Transovarial transmission was demonstrated in our study up to 12 generations. The mean infection rate for the progeny of fleas maintained on both cats and an artificial membrane system were comparable (64.3% and 58% respectively). Cats with no prior exposure to fleas were exposed to fleas infected with Rickettsia felis and monitored monthly for seroconversion via IFA. Blood samples were assayed for the presence of …

The Compliance-Seeking Process From The Perspective Of The Respondent: The Role Of Goals In Responses To Requests., Barbara L. Woods

LSU Historical Dissertations and Theses

This study examined compliance seeking from the perspective of recipients of direct requests with respect to types of responses, goals, liking, and locus of control. A total of 211 employed adults completed a survey that included responses to hypothetical request scenarios involving liked and disliked co-workers, measures of goals factors, and a measure of locus of control. Six types of responses were identified: simple agreement, elaborated agreement, simple refusal, refusal with reasons, request more information, and postpone decision. Participants reported a tendency to agree with requests, regardless of liking. Factor analyses revealed three-factor models for the liked and disliked conditions. …

Efficient Mapping Of Neural Network Models On A Class Of Parallel Architectures., Behnam Seyed Arad Jan 1997

Efficient Mapping Of Neural Network Models On A Class Of Parallel Architectures., Behnam Seyed Arad

LSU Historical Dissertations and Theses

This dissertation develops a formal and systematic methodology for efficient mapping of several contemporary artificial neural network (ANN) models on k-ary n-cube parallel architectures (KNC's). We apply the general mapping to several important ANN models including feedforward ANN's trained with backpropagation algorithm, radial basis function networks, cascade correlation learning, and adaptive resonance theory networks. Our approach utilizes a parallel task graph representing concurrent operations of the ANN model during training. The mapping of the ANN is performed in two steps. First, the parallel task graph of the ANN is mapped to a virtual KNC of compatible dimensionality. This involves decomposing …

Interactive Effects Of Weeds And Defoliating Insects In Soybean (Glycine Max)., Charles Frost Grymes Jan 1997

Interactive Effects Of Weeds And Defoliating Insects In Soybean (Glycine Max)., Charles Frost Grymes

LSU Historical Dissertations and Theses

Field experiments were conducted to evaluate the influence of simulated insect defoliation and full season weed competition on soybean (Glycine max (L.) Merr.) growth and yield. Weeds were johnsongrass (Sorghum halepense (L.) Pers.), common cocklebur (Xanthium strumarium L.), and hemp sesbania (Sesbania exaltata (Raf.) Rybd. ex A. W. Hill) at 15, 3, and 12 plants/6 m of row. Simulated defoliation at R2 and R5 soybean growth stages was accomplished by removal of 0, 1, or 2 leaflets per soybean trifoliate, which approximated 0, 33, and 66% defoliation, respectively. Averaged across defoliation levels and stages, johnsongrass, common cocklebur, and hemp sesbania …

Errand Into The Wilderness And America: An Analysis Of The Effects Of Puritan Symbols On The Perceived Purpose Of Education In America., E. Douglas Mcknight Jan 1997

Errand Into The Wilderness And America: An Analysis Of The Effects Of Puritan Symbols On The Perceived Purpose Of Education In America., E. Douglas Mcknight

LSU Historical Dissertations and Theses

Present day America is perceived as immersed in a moral crisis due to certain cultural conditions; that national identity has fractured, resulting in a pervading sense of uncertainty and anxiety about the future; that public schools, as institutions charged with preserving the symbols of national identity and a morality that is the concrete expression of those symbols, have failed and must be reformed; and finally, that only through "schooling" can America be saved from this current cultural crisis. This rhetorical trajectory has a history that extends back to the Puritans who settled in America during the early seventeenth century and …

Americans And German Youth In Nuremberg, 1945-1956: A Study In Politics And Culture., Harald Thomas Oskar Leder Jan 1997

Americans And German Youth In Nuremberg, 1945-1956: A Study In Politics And Culture., Harald Thomas Oskar Leder

LSU Historical Dissertations and Theses

While American policy makers needed three years after World War II to recognize the importance of re-educating German youth and to develop a consistent policy, a look at Nuremberg reveals that American representatives in the field started positive and constructive programs immediately after the war. American soldiers ignored non-fraternization, the Army became heavily involved in helping German communities survive, while the Youth Section of the Office of Military Government was the first to focus on persuasion instead of coercion in its re-education efforts. It designed long range programs to introduce young Germans to a democratic culture. Official American policy simply …

Postmodern Messiah: A Critical Ethnography Of Elvis Presley As A Site Of Performance., Daniel Weaver Heaton Jan 1997

Postmodern Messiah: A Critical Ethnography Of Elvis Presley As A Site Of Performance., Daniel Weaver Heaton

LSU Historical Dissertations and Theses

In this study I used a critical ethnographic approach to investigate Elvis as a site of performance where cultural identity, authority and representation are contextualized within the cultural practices of fans, people who love Elvis, and funs, people who do not love Elvis, but still elect to use Elvis as the basis for their cultural performances. I argued that fans and funs use performance as the agency of postmodern identity construction. I explored three performance events in which both fans and funs participated. Additionally, I examined the relationship of power and play between and within fan and fun culture. I …

The Recycling Potential Of Out-Of-Service Utility Poles For Engineered Wood Products., Han Roliadi Jan 1997

The Recycling Potential Of Out-Of-Service Utility Poles For Engineered Wood Products., Han Roliadi

LSU Historical Dissertations and Theses

This study on the recycling potential of out-of-service poles for use in engineered wood products involved determination of basic properties of used southern pine (Pinus sp.) utility poles and also manufacture of glued-laminated beams from these poles. Most of the defect-free portions of 25-year treated poles still retained adequate strengths comparable to those of freshly treated poles and untreated southern pine. Creosote contents, however, diminished with pole ages. The reduction in creosote content was correlated with lower decay resistance, poorer dimensional stability, and lower lumber recovery, but better gluability. The spectrometry method for creosote content determination was explored as an …

Modeling Hrm In Context: Examining The Role Of Human Resource Manager Discretion., Elyssa Blanton Schultz Jan 1997

Modeling Hrm In Context: Examining The Role Of Human Resource Manager Discretion., Elyssa Blanton Schultz

LSU Historical Dissertations and Theses

This dissertation presents a model focusing on human resource manager discretion and its role in influencing variations in HRM. Discretion, defined here as the latitude of action of human resource managers, is suggested as an important means of accounting for differing levels of constraint facing the HRM function. Because the model developed here focuses on discretion as a characteristic which is common to theories of choice and environmental determinism in organizational research, it is designed to stimulate future research that simultaneously considers predictions of HRM structure and content that have, to this point, been considered contradictory. In general, the results …

Landscape Change And Livestock In Sixteenth-Century New Spain: The Archival Data Base, Andrew Sluyter Jan 1997

Landscape Change And Livestock In Sixteenth-Century New Spain: The Archival Data Base, Andrew Sluyter

Faculty Publications

Despite the wealth of Mexican archival data pertinent to understanding the ecological interaction between livestock and landscape during the sixteenth century in New Spain, some fundamental methodological issues persist in the use of the mercedes, or land grants. The degree of completeness of the extant mercedes record and the de facto areal extents of the cattle and sheep estancias both remain uncertain. A cartographic method applied to mercedes for the central Veracruz lowlands addresses those issues and suggests a general method for rigorous analysis of the data base. That method demonstrates that the extant mercedes provide a nearly complete record …

Transgenic Dairy Cattle: Genetic Engineering On A Large Scale, R. J. Wall, D. E. Kerr, K. R. Bondioli

Faculty Publications

Amid the explosion of fundamental knowledge generated from transgenic animal models, a small group of scientists has been producing transgenic livestock with goals of improving animal production efficiency and generating new products. The ability to modify mammary-specific genes provides an opportunity to pursue several distinctly different avenues of research. The objective of the emerging gene "pharming" industry is to produce pharmaceuticals for treat-ing human diseases. It is argued that mammary glands are an ideal site for producing complex bioactive proteins that can be cost effectively harvested and purified. Consequently, during the past decade, approximately a dozen companies have been created …

Boris Yeltsin's Ascent To Power: Personae And The Rhetoric Of Revolution., Matthew Thomas Althouse Jan 1997

Boris Yeltsin's Ascent To Power: Personae And The Rhetoric Of Revolution., Matthew Thomas Althouse

LSU Historical Dissertations and Theses

This study is an examination of the rhetorical strategies utilized by Boris Yeltsin during his rise to prominence and his role in the second Russian revolution. By borrowing concepts from the study of revolutions in science, the author contends that Yeltsin used three distinct rhetorical personae, or modes of public presentation, to forward his discourse between 1985 and 1991. These personae include the revolutionary, the conciliatory, and the conservative. With this critical vocabulary, the author argues that Yeltsin's successes and failures hinged on his fitting use of rhetorical personae in relation to four exigencies during the late-Soviet era: the evolution …

Acute Effects Of Passive Muscle Stretching On The Stretch-Shortening Phenomenon., Andrew Cornwell Jan 1997

Acute Effects Of Passive Muscle Stretching On The Stretch-Shortening Phenomenon., Andrew Cornwell

LSU Historical Dissertations and Theses

Two experiments examined the acute effects of passive muscle stretching on the performance of a skill (vertical jump) which takes advantage of the stretch-shortening phenomenon. Because recent work suggests that passive stretching might impede the mechanisms (elastic and myoelectrical potentiation) thought to be responsible for this phenomenon, it was hypothesized that stretching would decrease the jump height of jumps executed with a preparatory countermovement (CMJ), but not the jump height of those initiated from a static, squatting position (SJ). In the first experiment, subjects performed CMJ and SJ jumps under two different conditions: after passively stretching the knee and hip …
