The higher classification of the Hesperiidae (Lepidoptera: Hesperioidea)

Creator:: Warren, Andrew D.
Abstract:: A comprehensive tribal-level classification for the world's subfamilies of Hesperiidae, the skipper butterflies, is proposed for the first time. Phylogenetic relationships between tribes and subfamilies are inferred using DNA sequence data from three gene regions: 943 bp of cytochrome oxidase subunit I (COI) (in the mitochondrial genome), 739 bp of...

Hydrological consequences of two native shrubs in semi-arid Senegal : patterns, processes, concepts and methods

Creator:: Kizito, Fred
Abstract:: Water availability is a critical limiting element in semi-arid ecosystem productivity and presents particular challenges in Sahelian countries such as Senegal. The landscapes are characterized by the presence of two common semi-arid shrubs (Piliostigma reticulatum and Guiera senegalensis), both of which may be important hydraulic regulators in these water-limited ecosystems....

The knowledge base and instructional practices of two highly qualified experienced secondary mathematics teachers

Creator:: Beauchman, Molly Laverne Taylor
Abstract:: The purpose of this study was to investigate the knowledge base and instructional practices of two highly qualified experienced secondary mathematics teachers within the context of their classrooms during a unit in a geometry class. Data collected from interviews, classroom observations, pre and post-observation questionnaires, and detailed analyses of several...

Examination of the role host-selective toxins play in fungal-plant interactions

Creator:: Andrie, Rachael M.
Abstract:: Pyrenophora tritici-repentis, causal agent of tan spot of wheat, produces multiple host-selective toxins (HSTs), including Ptr ToxA, encoded for by ToxA, Ptr ToxB, encoded for by ToxB, and Ptr ToxC. Variable distribution of these three HSTs among different isolates of P. tritici-repentis, both singularly and in all possible combinations, defines...

Voices of leadership : experiences of people of color in a community leadership development program

Creator:: Hiyane-Brown, Katherine H.
Abstract:: The purpose of this study was to describe and record the experiences of people of color in a community leadership development program. Selected people of color were asked to describe their experiences as participants in the American Leadership program in Tacoma-Pierce County in the State of Washington. The American Leadership...

Understanding university students' construction of their hidden disability identity

Creator:: Bentley-Townlin, Tracy
Abstract:: This study co-investigated with students with hidden disabilities the phenomenon of disability identity. This qualitative study utilized phenomenology and strategies proposed by Paulo Freire in an effort to understand identity development specific to individuals with hidden disabilities. There were seven students from a medium-sized, public university who participated in the...

Public trust / private interest : practical and philosophical issues for community colleges and their contract education programs

Creator:: Lindstrom, Eric L.
Abstract:: Community colleges are being pressured to increase their direct support of the economic development agendas of their communities, their states, and even the nation. These pressures develop both externally and internally, and are exacerbated when increased demands for access to community college education must be met with chronically flat-lined or...

Magnetically assisted liquid-solid fluidization in a gradient magnetic field : Theory and application

Creator:: Sornchamni, Thana
Abstract:: Development of efficient methods for the destruction of solid wastes and recovery of valuable resources is needed to support long-duration manned missions in space. In particular, these technologies are required for deployment in hypogravity and microgravity environments, such as at the lunar or Martian surfaces. Gradient Magnetically Assisted Fluidized Bed...

Application of buckling behavior to evaluate and control shape variation in high-temperature microlamination

Creator:: Wattanutchariya, Wassanai
Abstract:: The miniaturization of energy, chemical and biological systems for distributed and portable applications, known as process intensification, is realized by the enhancement in heat and mass transfer performance within high surface-to-volume ratio microchannels. Fabrication of devices for process intensification is achieved in part by microlamination techniques. These techniques consist of...

Evolution of aposematic warning coloration in parasitic wasps (Hymenoptera:Braconidae)

Creator:: Leathers, Jason Wayne
Abstract:: Many Hymenoptera, with their painful stings and noxious chemical defenses, exhibit bright aposematic warning color patterns and are the most frequently mimicked group of organisms. Such aposematic color patterns are found in parasitic wasps of the Neotropical Compsobracon group (Braconidae). Many members of this group exhibit color patterns similar to...
