Insecticide Resistance And Resistance Mechanisms In The Southern House Mosquito, Culex Quinquefasciatus., Jeffrey Dwayne Stancil

LSU Historical Dissertations and Theses

Significant resistance to malathion and resmethrin was found in insecticide-treated field populations of adult Culex quinquefasciatus , Say, compared with a laboratory and non-treated field strain. Resistance to both insecticides varied during the active control season and was associated with the frequency of insecticide application. Geographic variations in resistance levels were noted, and significant differences occurred between separate populations within the same mosquito control districts. Four model substrates were assessed for their suitability in detecting elevated esterase activity associated with malathion resistance. Esterase activities towards all substrates were significantly higher in field stains than a laboratory strain. Esterase activities toward …

LSU Historical Dissertations and Theses

The comparative efficacy and quality characterization of juice by six extraction methods utilizing either frozen or fresh 'Texas Star' mayhaw (Crataegus opaca Hook. and Arn.) fruit obtained from the 1998 and 1999 crop season were conducted according to temperature (cold-press or hot-press extraction) and fruit pulp pretreatment (whole or pulverized fruit with or without pectolytic enzyme). Extraction methods were steam extraction using whole fruit without added pulp juice (SE); steam extraction using whole fruit with added pulp juice (SEP); cold-press extraction using whole fruit (CPE); cold-press extraction using finely macerated fruit pulp (CPEG); hot-press extraction using finely macerated fruit pulp …

Consumers' Reasoned Behavior Toward American Alligator Leather Products., Yingjiao Xu

LSU Historical Dissertations and Theses

This study determined consumers' perception of and attitude toward American alligator leather products and evaluated factors affecting consumers' purchase intention of the products. The Fishbein and Ajzen (1975, 1980) theory of reasoned behavior served as the theoretical framework for the study. The influence of six variables on purchase intention was measured: attitude toward purchase based on product attributes, subjective norm with respect to purchase, traditional attitude toward fashion products (fashion involvement), personality traits (self-confidence and self-consciousness), price perception (price-quality schema and prestige sensitivity), and demographics. The correlation between consumers' usage of media for fashion information and purchase intention was also …

Litterfall Dynamics And Nutrient Cycling In Mangrove Forests Of Southern Everglades, Florida And Terminos Lagoon, Mexico., Carlos Antonio Coronado Molina

LSU Historical Dissertations and Theses

The objective of this dissertation was to investigate the processes that control litterfall and nutrient dynamics in two contrasting mangrove ecosystems at the Southeastern (SE) Everglades and Terminos Lagoon. The main objectives were: (a) to determine the spatial and temporal variability of litterfall dynamics, (b) to evaluate the relative importance of nutrient use efficiency as a nutrient conservation mechanism along a natural nutrient gradient, and (c) to assess the relative importance of nutrient resorption on litterfall dynamics. Two hypotheses were tested: (a) mangrove species living in nutrient-poor environments and in nutrient-rich environments do not differ in the efficiency in using …

Female High School Biology Students' Biofilm -Focused Learning: The Contributions Of Three Instructional Strategies To Patterns In Understanding And Motivation., Jo Dale Hill Ales

LSU Historical Dissertations and Theses

This exploratory study examined three instructional strategies used with female high school biology students. The relative contributions of the strategies to student understanding of microbiology and motivation in science were analyzed. The science education community targeted underachievement in science by implementing changes in content and practices (NRC, 1996). Research suggested that teachers facilitate learnirig environments based on human constructivism (Mintzes, Wandersee, & Novak, 1997) that is rooted in meaningful learning theory (Ausubel, Novak & Hanesian, 1978). Teachers were advised to use both visual and verbal instructional strategies (Paivio, 1983) and encourage students to construct understandings by connecting new experiences to …

The Rhetoric Of The Benign Scapegoat: President Reagan And The Federal Government., Stephen Wayne Braden

LSU Historical Dissertations and Theses

Ronald Reagan deservedly attained the moniker "The Great Communicator" due to his rhetorical prowess. This dissertation addresses an aspect, governmental scapegoating, of Reagan's rhetorical strategy. Traditional scapegoating theory claims that the scapegoat is either killed or driven from the community. However, I claim that Reagan profited by making a unique use of the scapegoat, one that was benign, the government remained essentially unscathed. The means to analyze Reagan's discourse is Kenneth Burke's cycle of guilt, victimage, redemption and rebirth. Ten speeches of President Reagan are analyzed: both of his Inaugural Addresses, his Economic Recovery Speech, and his seven State of …

An Inquiry Into The Impact Of Teacher Variances Within The Implementation Of The Success For All Reading Program In Two School Districts., Karen Parker Guillot

LSU Historical Dissertations and Theses

Elementary school students walk single file to their respective classrooms where literacy should miraculously transpire. For literacy to occur, some schools adopt reading programs provided by their local district or state, while others utilize externally developed program designs. This multiple-case qualitative inquiry examined the externally developed program, Success for All, a program designed to benefit high poverty schools, founded by Robert Slavin and Nancy Madden as well as their cohorts at Johns Hopkins University. This research study examined the variances among seven teachers implementing the SFA reading program, "Reading Wings," in three schools in two school districts in Louisiana. It …

The Effects Of The Laboratory On College Students' Understanding Of Evolution: Implications For Conceptual Change., Lorna Benita Holtman

LSU Historical Dissertations and Theses

This study investigated eighty junior and senior college students' understanding of evolutionary biology concepts in lecture-only and lecture-laboratory settings. The evolution lab stressed the processes of evolution, and involved simulations, experiments, discussions, report writing, and reading. Test scores do not reveal everything about the actual process of learning in the laboratory. This study examined conceptual change patterns over a period of one semester using in-depth interviews with eight participants. The study revealed that the lecture-laboratory group performed better than the lecture-only group on certain shared items on the objective examination. The interview participants showed various patterns of conceptual change; that …

The Function Of Speech (Verbal Mediation) On Corresponding Academic And Social Behavior., Kimberly Jo Callicott

The role of language in self-control has been of interest to researchers across continents and time. This study attempted to isolate the functional role of language in relationship to subsequent academic and task engaged behaviors with four students aged 10--14. The students were diagnosed with Emotional or Behavioral Disorders had normal intelligence and were receiving their education at an alternative placement facility. The study used a single subject design and exposed the subjects to conditions of self-declaratory speech (SDS), SDS and reinforcement for correspondence, a return to baseline, SDS and reinforcement for correspondence, and SDS with delayed reinforcement. Results of …

Congestion Control Mechanisms For Internet Multicast Transport Protocols., Elias George Khalaf

LSU Historical Dissertations and Theses

Internet Multicasting has emerged in the last few years as the inevitable method for efficiently delivering replicated data to multiple recipients in large scale internets. More specifically, Reliable Multicast Transport Protocols have been the subject of intensive research in recent years. The goal of such research was mainly to develop reliable and scalable protocols to efficiently and reliably deliver data to receivers, and at the same time reduce congestion on the network. In this research, we propose a new generic family of protocols, called the K family of protocols, that focus on congestion control by reducing the processing requirements on …

Simulations And Algorithms On Reconfigurable Meshes With Pipelined Optical Buses., Anu Goel Bourgeois

LSU Historical Dissertations and Theses

Recently, many models using reconfigurable optically pipelined buses have been proposed in the literature. A system with an optically pipelined bus uses optical waveguides, with unidirectional propagation and predictable delays, instead of electrical buses to transfer information among processors. These two properties enable synchronized concurrent access to an optical bus in a pipelined fashion. Combined with the abilities of the bus structure to broadcast and multicast, this architecture suits many communication-intensive applications. We establish the equivalence of three such one-dimensional optical models, namely the LARPBS, LPB, and POB. This implies an automatic translation of algorithms (without loss of speed or …

Comparative Biology And Ecology Of The Formosan Subterranean Termite, Coptotermes Formosanus Shiraki (Isoptera: Rhinotermitidae) In Louisiana., Huixin Fei

LSU Historical Dissertations and Theses

A laboratory study was conducted to investigate the effects of sibship patterns and different origins of colonies on mate mortality and growth of incipient colonies in the subterranean termite, Coptotermes formosanus Shiraki. Primary reproductives from New Orleans in nonsibling pairs had significantly higher mortality than sibling pairs. The average egg production for sibling and nonsibling pairs showed no overall significance in the first oviposition period, however, the average number of larvae was consistently higher in nonsibling than in sibling-founded colonies from New Orleans. After two years, the average number of eggs or larvae present in nonsibling-founded colonies was significantly higher …

Narrative Structure And Characters In The Nanzi Stories Of Curacao: A Discourse Analysis., Joke Maaten Mondada

LSU Historical Dissertations and Theses

This dissertation develops a new approach to the analysis of narratives by combining the analysis of narrative structure and character analysis. Through the in-depth analysis of two stories of a collection of 32 Nanzi stories (from Curacao), which are spider/trickster stories in Papiamentu, I develop a method to analyze the structure of the Nanzi stories. My method is based on the determination of narrative division into (1) episodes, organized as macro-propositions under a macro-structure (Van Dijk 1982; 1992); (2) different sections (six), based on narrative and free clauses (Labov 1972); and, (3) major events (Barthes 1975; Chatman 1978). By applying …

Rhetoric, Prudence, And The "Morrill Act" Of 1862., Jason Brian Munsell

LSU Historical Dissertations and Theses

The Morrill Act was the political telos of numerous rhetorical messages calling for pedagogical changes in higher education. This study examines the role of prudence in four of them. The method is a mode of textual criticism that attempts to capture the bifurcated sense of rhetorical invention: The immediate rhetorical situation, and the cultural grammar that constrains the rhetor performatively. The author illustrates how the relevant rhetorical strategies/gestures within each text and the text's textual context pointed to a certain conception of prudence. Historically, the author argues that the struggles between different notions of prudence impacted political, pedagogical action. Theoretically, …

The Effect Of Negative Events And Firm Responses On Brand Associations, Organizational Associations, And Brand Evaluations., Chris Patrick Pullig

LSU Historical Dissertations and Theses

This dissertation examines the impact of negative events and firm responses to such events on an associative network of brand knowledge; key consumer brand and organizational associations, risk perceptions, and brand response variables. To accomplish this objective the issue of how negative event information is integrated with an existing brand/organizational image was assessed within the framework of a consumer-brand relationship. Two between-subjects experiments were conducted using adult consumers as subjects. In Study One, negative events were found to affect associations linked to the brand and limit the brand's ability to fulfill the consumer-brand relationship. Two types of events were identified, …

Third -Party Organization Endorsement Of Products: An Advertising Cue Affecting Consumer Pre-Purchase Evaluation Of Goods And Services., Dwane Hal Dean

LSU Historical Dissertations and Theses

Observation of advertising in current use suggests that a new type of ad is emerging as a product positioning tool. The new ad features third-party organization (TPO) product endorsement as one of the elements of the ad (e.g. "Car of the Year" award by Motor Trend magazine, and "4-star" mutual fund rating from Morningstar). Marketers appear to be using favorable TPO statements about their products to enact their positioning strategy. This dissertation proposed that TPO endorsements are perceived by consumers as extrinsic quality cues, similar to the established quality cues of brand, price, retailer reputation, and warranty. This proposition was …

Who Owns The Customer? The Emerging Law Of Commercial Transactions In Electronic Customer Data, Jane Kaufman Winn, James R. Wrathall

Articles

The Information Revolution is changing the way commerce acted and value is defined within transactions. Before the Internet and "e-business" took center stage, "electronic commerce" meant electronic data interchange, just-in-time inventory systems, supply chain automation, and corporate reengineering.

But the rise of the Internet as a communications medium has coincided with a shift in management focus, from merely trying to improve the efficiency of business logistics systems to a more holistic perspective on improving customer relationships. Intangible assets such as intellectual property rights, human capital in the form of employee knowledge, and established relationships with customers and suppliers are playing …

Orchestrated Synergism: The Nurse-Leader As Facilitator In Collaborative Caring, Nancy C. O'Rourke

UNF Graduate Theses and Dissertations

Little is known of the way that nurses' roles have evolved within a hospital setting in which efficient and affective interventions include caring for sicker patients. The emergence of the Patient Care Coordinator (PCC) is one role that nursing developed to participate in an interdisciplinary collaborative team approach to caring for sicker patients.

This qualitative study examined the exemplary role of eleven PCCs who practice in a regional nonprofit medical center. Research methodologies included interview, non-participant observation, and analysis of historical data. Interview questions were developed from the literature review on collaboration, caring, expertise, communication, and knowing the patient. Cognitive …

Cognitive Approaches To The Explanation Of Gambling Behaviour: An Evaluation, Antony Dyson Laurie

School of Psychology Theses

This thesis investigates three hypotheses in relation to the cognitive explanation of normal and problematic gambling behaviour. The "strong cognitive hypothesis" takes the view that if cognitive processes alone account for different levels of play, then the order of the events experienced during a task may be a good predictor of the levels of play. Four large scale experiments are presented focusing on the Illusion of Control, particularly the order effects originally observed by Langer and Roth (1975). Drawing on Hogarth and Einhom's (1992) belief adjustment model an adjusted methodology is employed making the paradigm resemble the real gambling decision …

The Cognitive-Initiative Account Of Depression-Related Impairments In Memory, Paula T. Hertel

Psychology Faculty Research

The many and diverse interpretations of the word control make it clear that control constitutes a fundamental concern in most areas of psychology. In an illustration of this diversity, I described my interest in controlled uses of memory at a social gathering; my new acquaintances, without realizing the non sequitur, subsequently raised issues about self control and loss of control-issues much more relevant to their own interests in psychological phenomena than are my narrow musings. Yet a second thought devoted to the semantics of control reveals underlying commonalities. For example, when older people begin to have problems with controlled …

Modelling Machine Induced Noise And Vibration In A Ship Structure, Weihui Wang

School of Engineering, Computing and Mathematics Theses

Most high speed vessels are fitted with powerful high speed engines which are installed in confined spacesa nd, as a consequencec, ausea n extremely high level of noise and vibration. Often structure-borne sound power is transmitted to a sound carrying structure from a source via a number of contact points. In turn, the noise and vibration are propagated in the structure and could possibly cause an undesired noise radiation. In this study, a model for predicting power flow based on the mobility theory has been addressed. The unique parts of the study include the establishment of the relationship of mobility …

Prognosis - Historical Pattern Matching For Economic Forecasting And Trading, Georgios Nikolaos Banavas

School of Engineering, Computing and Mathematics Theses

In recent years financial markets have become complex environments that continuously change and they change quickly. The strong link between the continuous change in the markets and the danger of losing money when trading in them, has made financial studies a domain that concentrates increasing scientific and business attention. In this context, the development of computational techniques that can monitor recent financial events can process them according to their similarity with historical data recordings, and can support financial decision making, is a challenging problem. In this work, the principal idea for tackling this problem is the integration of 'current' market …

The Systemic Redesign Of Manufacturing Systems In Small To Medium Sized Enterprises, John William George Bradford

School of Engineering, Computing and Mathematics Theses

The research problem was to develop a new approach for redesigning manufacturing systems within Small to Medium sized Enterprises (SMEs). Field observation together with literature review showed that methodologies propounded in theory were not being applied in practice. The research presents a new methodology for the systemic redesign of manufacturing systems within SMEs. The methodology consists of a four phase iterative design strategy consisting of Planning, Risk Assessment, Action and Evaluation leading to the next Planning phase. This is given a systemic basis through four perspectives: Structure; People; Process; and Technology; which frame and guide the Planning phase. Prior to …
