This study investigated the adolescent self-concept. The concern was with the relationship between peer status as measured by a reputation scale and self-concept as measured by how an individual feels he is perceived by others.

The purpose of this study was to investigate the impact of basic communication fidelity (BCF) upon the perceptions of national observers toward national and international communicators across a variety of group interaction variables. Research is presented which indicates that (1) international students are typically perceived less favorably than national students across a variety of interpersonal variables; (2) as BCF increases, more favorable ratings are attributed to communicators across interpersonal variables; and (3) increased BCF may be able to mitigate the less favorable impressions national observers attribute to international communicators.

A method was developed for extending a fine-scaled forest gap model to a watershed-scaled landscape, using the Eastern Cross Timbers ecoregion as a case study for the method. A topographic wetness index calculated from digital elevation data was used as a measure of hydrologic across the modeled landscape, and the gap model modified to have with a topographically-based hydrologic input parameter. The model was parameterized by terrain type units that were defined using combinations of USDA soil series and classes of the topographic wetness index. A number of issues regarding the sources, grid resolutions, and processing methods of the digital elevation data are addressed in this application of the topographic wetness index. Three different grid sizes, 5, 10, and 29 meter, from both LiDAR-derived and contour-derived elevation grids were used, and the grids were processed using both single-directional flow algorithm and bi-directional flow algorithm. The result of these different grids were compared and analyzed in context of their application in defining terrain types for the forest gap model. Refinements were made in the timescale of gap model’s weather model, converting it into a daily weather generator, in order to incorporate the effects of the new topographic/hydrologic input parameter.
