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

LSU Historical Dissertations and Theses

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 …

A Method To Discriminate Species From Hydroacoustic Fish Sampling Systems., Rui De Paula E Silva

LSU Historical Dissertations and Theses

Samples of species and size composition obtained by trawling were matched with the corresponding echo-distributions from two hydroacoustic and trawl surveys in the western Indian Ocean, off Mozambique, and in two surveys in the northern Gulf of Mexico. In the Mozambique surveys, a Simrad EY-M echosounder was used and the data was analyzed by applying the Craig & Forbes algorithm. In the Gulf of Mexico surveys, a BioSonics Dual-beam System (Model 102 echosounder, ESP echo-integrator, and ESP dual-beam processor) was used. The results obtained show that, provided that a particular hydroacoustic and trawl sample yielded a stable size-distribution of the …

Karel Husa's Concerto For Alto Saxophone And Concert Band: A Performer's Analysis., Kevin Robert Burns

LSU Historical Dissertations and Theses

Concerto for Alto Saxophone and Concert Band by Karel Husa is regarded as one of the great wind concertos of the 20th century. It is an atonal composition with an unusual and complex rhythmic language. In and of itself analysis is a creative and intellectual endeavor. It also can give the performer a deeper understanding of the piece so that he or she can give a better performance. This paper is the first analysis of Husa's concerto to use Allen Forte's set theory method of melodic and harmonic analysis. The rhythm analysis is unique in that it recognizes the philosophical …

Effects Of Microstructure And Crystallographic Texture On Yield Behavior Of Aluminum-Copper-Lithium 2195 Plate., Karen Elizabeth Crosby

LSU Historical Dissertations and Theses

The focus of this research is to study the effects of deformation and aging on the yield behavior of precipitation-hardened Al-Cu-Li alloys, specifically AI-Cu-Li 2195 plate. Al-Cu-Li 2195 is a relatively new and exceptionally strong, yet lightweight aluminum alloy. Experimental methods applicable to mechanical/structural engineering and materials science problems provide the means for understanding the interrelation of deformation, microstructure, and crystal orientation (texture) as they affect the mechanical properties of crystalline materials. Yield strength is a vital mechanical property in that it defines the boundary of stress that may be applied to a part before a permanent, in some cases, …

Wave Profile For Antiforce Class Ii Waves, Rory Roberts, Mostafa Hemmati

Journal of the Arkansas Academy of Science

Breakdown waves propagating in the opposite direction of the applied electric field force are referred to as antiforce waves. Breakdown waves moving into a pre-ionized medium are referred to as Class II waves. Using a one-dimensional, steady state, three-fluid, hydrodynamical model and considering the electrons as the main element in propagation of ionizing waves, we have derived the proper boundary conditions for antiforce waves moving into a preionized medium. Using the new boundary conditions and for several current values ahead of the wave, the set of electron fluid dynamical equations (equations of conservation of mass, momentum, and energy coupled with …

Field Interpretation Of Latitude And Longitude In Arkansas: A Portable Coordinate Projection, William R. Teague

Journal of the Arkansas Academy of Science

Two- and three-dimensional coordinate systems are fundamental to most quantitative mapping applications. The Geodetic, Universal Transverse Mercator (UTM),and State Plane systems have traditional roles in various science, surveying, and government agency engineering applications. The coordinates of three-dimensional Geodetic system are latitude, longitude, and height above ellipsoid (HAE).Because of its ability to cope with the intrinsically three dimensional character of the earth's surface, the Geodetic system is capable of supporting precise relative positioning and very high accuracy computations of distance between any two positions on or near the earth's surface. The two-dimensional UTMand State Plane systems are extremely useful for the …

Versatile Apparatus For Measuring Kinetics Of Gaseous Reactions By A Relative Method, Edmond W. Wilson Jr., Holly A. Sawyer, Amber A. Sawyer

Journal of the Arkansas Academy of Science

It is important that accurate, reproducible values for the rates of chemical reactions occurring in the atmosphere be obtained. The value of accurate kinetics measurements is to improve the accuracy of mathematical models used to forecast the state of the atmosphere. We describe a versatile, robust apparatus for obtaining atmospheric reaction rate values and their temperature dependencies by a relative method. This relative method has the advantage over absolute methods in that errors due to impurities and adsorption on walls of the reaction apparatus are minimized. In addition, relative values serve as an important verification for absolute values. The apparatus …

Systems Integration: A Tool For Project Monitoring In The Public Sector, Baharum Noriati

Student Works (2000-2009)

Many computerized systems today operate within organizational boundaries. In the Malaysian public sector, early systems were developed to solve organizational business functions. In the course of developing application systems to resolve specific needs, these organizations hardly look beyond the boundaries of their business domain. This phenomenon led to the existence of islands of information systems within the government sector. In this study, the researcher proposed to look into the issues of systems integration (SI) within the public sector, in general and subsequently proceed to an area where SI is deemed to be appropriate. Project monitoring for the government in Malaysia …

Erbium-Ytterbium Codoped Fiber Amplifiers, Wai Yee Chan

Student Works (2000-2009)

The amplification characteristics of an Erbium/Ytterbium codoped fiber amplifier(EYDFA) pumped in both the 800nm and 980nm pump bands is reported. With -3m long Er-Yb fiber, the 813nm pumped-EYDFA shows small-signal gain exceeding 20dB over a 20nm bandwidth in the l.Sµm region where the peak gain of 38.4dB is achieved at 1535nm. A low noise figure of ~3.6d8 is also achieved at 1550nm. However, it is found that 980nm pumped­EYDF A suffers lower gain due to the effect of nonsaturable absorption by Yb³⁺ ions which causes high pump poWer loss, thus degrades the signal amplification in Er³⁺ system. Compared to the …

Devitrification Of Volcanic Glasses In Konya Volcanic Units, Turkey, Zehra Karakaş, Selahatti̇n Kadi̇r

Turkish Journal of Earth Sciences

The study area is composed of volcanic, sedimentary and volcano-sedimentary units, which are exposed south and southwest of the city of Konya. XRD analysis indicates that the volcanic units contain halloysite, kaolinite, smectite, illite and sepiolite type clay minerals and opal-CT, feldspar, quartz, minamiite and jarosite type non-clay minerals. SEM studies show that volcanic glasses, which are the main component of the volcanic units, appeared as curviplanar, vesicular-planar and in highly fractured shapes. Fractures and dissolution voids of the volcanic glasses are generally filled by hexagonal kaolinite, fibrous halloysite and smectite. Mineralogical and micromorphological observations indicate that clay minerals were …

Dynamics Of Interfacial Polymers In Composites, Frank D. Blum, Wuu-Yung Lin

Chemistry Faculty Research & Creative Works

Much experimental and theoretical work has been done on the behavior of adsorbed polymers. However, not much work has focused on the dynamics, especially segmental dynamics, of the adsorbed polymers. This is especially true of filled polymer or composite systems as the interfacial layers in these systems are difficult to study with most techniques. NMR is not restricted to use in optically clear samples and its use in the characterization in the surface polymers has been reviewed. In our laboratory, we have found that deuterium NMR could be used to probe the segmental dynamics of adsorbed polymers. The position of …
