Sr‐ And Ni‐Doped Lacoo3 And Lafeo3 Perovskites: New Cathode Materials For Solid‐Oxide Fuel Cells, Kevin Huang, Hee Y. Lee, John B. Goodenough

Faculty Publications

An improved cathode material for a solid‐oxide fuel cell would be a mixed electronic and oxide‐ion conductor with a good catalytic activity for oxygen reduction at an operating temperature T _op ≥ 700°C and a thermal expansion matched to that of the electrolyte and interconnect. We report on the properties of Sr‐ and Ni‐doped LaCoO₃ and LaFeO₃ perovskites that meet these criteria. Single‐phase regions were determined by X‐ray diffraction, and thermogravimetric analysis measurements were used to obtain the temperatures above which oxygen loss, and hence oxide‐ion conductivity, occurs. The conductivity and Seebeck measurements indicate the coexistence of both …

Host Plant Alters The Shape Of The Functional Response Of An Aphid Predator (Coleoptera: Coccinellidae), Frank J. Messina, J. B. Hanks

Biology Faculty Publications

The response of the lady beetle Propylea quatuordecimpunctata (L.) to the density of the Russian wheat aphid, Diuraphis noxia (Mordvilko), was measured in petri dish arenas as well as on plants with divergent leaf architectures. Logistic regression was used to distinguish the shape of the functional response (type II or III), and nonlinear least-squares regression was used to estimate attack coefficients (a) and handling times (Th). In dishes, the behavior of both beetle larvae and adults closely conformed to a type II response. Estimates of a and Th on whole plants were considerably different from those obtained from dishes, and …

The Relationship Between Ethnic Identity, Self-Esteem, Emotional Well-Being And Depression Among Lakota/Dakota Sioux Adolescents, Susan M. Pittenger

Psychology Theses & Dissertations

Despite conceptual support linking ethnic identity and psychological adjustment among Native Americans, empirical research examining this relationship remains limited. In light of recent developments in the area of ethnic identity research, including alternative conceptual models, improved methodologies, and more sophisticated measures, this study examined the relationship between ethnic identity, self-esteem, emotional well-being, and depression among Native American reservation youth.

The relationship between the predictor variables of American Indian ethnic identity, White-American identity and bicultural identity, and the criterion measures of self-esteem, emotional well-being, and depression were examined for 137 Lakota/Dakota Sioux reservation youth. Participants completed surveys including the Multigroup Ethnic …

Thermodynamic Modeling And Analysis Of Human Stress Responses, Satish C. Boregowda

Mechanical & Aerospace Engineering Theses & Dissertations

A novel approach based on the second law of thermodynamics is developed to investigate the psychophysiology and quantify human stress level. Two types of stresses (thermal and mental) are examined. A Unified Stress Response Theory (USRT) is developed under the new proposed field of study called Engineering Psychophysiology. The USRT is used to investigate both thermal and mental stresses from a holistic (human body as a whole) and thermodynamic viewpoint. The original concepts and definitions are established as postulates which form the basis for thermodynamic approach to quantify human stress level. An Objective Thermal Stress Index (OTSI) is developed by …

Constructing Identities And Defining The Nation: Germany Since 1949., Frank Anthony Allevato

Graduate Theses, Dissertations, and Problem Reports (ETD)

Not long after Germans began the historic task of dismantling the Berlin Wall in 1989, their country was again reunited after forty-five years of division. For the second time in less than a century, a majority of Europe’s Germans were brought together under the banner of a single political sovereignty. As the enlarged Federal Republic psychologically reorients and physically reconstructs itself, the event is likely to have continued European and worldwide implications. Understanding the new Germany’s internal development and its evolving self-perceptions is to conceive of the country’s role now and in the years ahead; central to understanding Germany today …

Gendered Expectations: An Exploration Of Identity And Power In The Life Of Katherine Of Aragon., Jennifer R. Daum

Graduate Theses, Dissertations, and Problem Reports (ETD)

How is it that Katherine of Aragon, a woman seemingly destined for a major impact on world events, has been relegated to the role of scorned wife and stubborn obstacle to historical progress? Beliefs about women’s roles limited Katherine while she was alive and influenced historical interpretations about her after her death. Katherine’s own interpretation of her role as a wife and mother evolved out of her perceptions of the opinions of others. The role that others had created for her was rigidly interpreted and internalized by Katherine. By not allowing herself to be used as a pawn by either …

Language Imperialism Versus Linguistic Rights: The Case Of Native Americans., Jonathan Woodruff Maffay

Graduate Theses, Dissertations, and Problem Reports (ETD)

From the days of the Old Testament and Tower of Babel through the nineteenth century efforts to create artificial languages, the human race has longed for a universal language. Its purpose would be to bind the linguistically diverse people of the world into a cohesive whole. With English apparently well on its way to becoming just such a universal language, many people are now growing concerned at the prospect. For them English is an imperial language that threatens the world’s rich cultural and language complexity. Linguistic rights activists have now begun trying to counter this universalizing trend with language repair …

This is a an examination of those Americans who went to the Soviet Union to live and work during the interwar period, and what became of them. Why they went, how many went, and whether they survived the experience. American attitudes, both private and public of the Soviet Union are also discussed.

Documentation: "Conversations: Picasso And His Paintings"., Sonda Folk Cheesebrough

Graduate Theses, Dissertations, and Problem Reports (ETD)

In planning and preparing a project for a Masters degree in Art Education my concerns and intentions were to design and implement a learning experience that would teach an art history topic and involve children in theatre production from the beginning stages to final production, integrating theatre as well as art history into the elementary art curriculum. This would involve designing a production in which the subject would be based in the area of art while the vehicle for the subject would be live theatre. Through this project I hoped to create a better and more memorable understanding of the …

A Study Of Impact Using 80-Derometer Rubber., Steven Harold Howard

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this work was to model and test an intermediate material that would absorb impact loads induced during deployment of a deployable rollover protective structure (ROPS) designed for use on a farm tractor. The design criteria required that the intermediate material, under compressive loads, maintain the integrity of all moving parts while introducing a minimum impact time of 0.005 seconds. A "ring" shaped part made of 80-Derometer rubber (a product of the Goodyear Corporation) was incorporated into the impact region of the ROPS deployment mechanism. Theoretical calculations were made based on energy balance equations and 2-D Working Model …

The Impact Of Egalitarian Children's Literature On Occupational Sex Role Stereotyping In Kindergartners And First Graders., Robin Ann Mayer

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study aimed to determine if reading children books about people in nontraditional occupations would decrease occupational sex role stereotyping. The study also attempted to identify correlations between students’ occupational sex role stereotyping and the following demographic variables: age, gender, parents’ socioeconomic status, mother’s employment, and traditionality of mother’s employment. One hundred twelve kindergartners and first graders from two rural schools in West Virginia were administered a questionnaire, as a pretest, to determine the degree of which they stereotype 14 occupations according to sex. Of the 14 occupations, 5 were traditionally female sex-typed, 7 were traditionally male sex-typed, and 2 …

An Object Relationship Framework And Persistence In Java., Srinivas S. Vangari

Graduate Theses, Dissertations, and Problem Reports (ETD)

The main objective of this thesis is to provide the design and implementation of an object relationship framework in Java where objects can form relationships with other objects dynamically at runtime. Relationships among objects have long been recognized as the important semantic constructs facilitating ease of analysis & design of large complex systems. Almost all modeling techniques have notations to describe the existence of relationships among software components. But unfortunately the relationships identified in analysis stage could not be mapped to the equivalent high-level language constructs during the implementation because of lack of high level semantic support for relationships in …

The purpose of this research was to determine the general content, topics and sub-topics, priorities of the content, and methods of instructional delivery for a women's health component within the Internal Medicine residency program at West Virginia University. Panel members chosen for the study were MD's and PhD's who worked in a health-related field for at least two years and had an interest in women's health. A modified Delphi method was used for this study to determine the content. Panel members also identified their current and preferred methods of instructional delivery in a separate section of the study. The panel …

Theory Of Mind Development And Attentional Processes In Young School Children., Amy Gillies Wilson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The following study explored relations between theory of mind understanding, attention, language ability, and general intelligence. Scores on measures of auditory processing (Test of Auditory Reasoning and Processing Skills), language comprehension (Test of Auditory Comprehension of Language, Revised), matrix completion (Raven's Colored Progressive Matrices), false belief and recursive thinking understanding were obtained along with teacher ratings of children's self-regulation as measured by Attention and Hyperactivity subscales of the Conner's Rating Scale. Analysis of zero-order correlations revealed self-regulation to be negatively correlated with recursive thinking, while age, general intelligence, auditory processing, and language ability were positively correlated with theory of mind …

Organizational Culture And Leadership At Berea College: An Historical Inquiry Into Saga Development And Underlying Cultural Assumptions., Gerald Emerson Wood

Graduate Theses, Dissertations, and Problem Reports (ETD)

Culture is a pervasive concept that is not easily encompassed in any one definition. Culture within an organization is both process and product. It is both a dynamic agent of influence within the temporal and spatial context of organizational life and an object of study approached from the actor's point of view and thickly described. My general interest is in the cultural context of colleges, and more specifically in the part that culture has played in the formation and transformation of the mission and role of Berea College as it has sought to educate marginalized people for nearly 150 years. …
