    SPATIALLY EXPLICIT MODEL OF AREAS BETWEEN SUITABLE BLACK BEAR HABITAT IN EAST TEXAS AND BLACK BEAR POPULATIONS IN LOUISIANA, ARKANSAS, AND OKLAHOMA

    Although black bears (Ursus americanus, Ursus americanus luteolus) were once found throughout the south-central United States, unregulated harvest and habitat loss resulted in severe range retractions and by the beginning of the twentieth century populations in Oklahoma, Louisiana, Texas and Arkansas were nearing extirpation. In response to these losses, translocation programs were initiated in Arkansas (1958-1968 & 2000-2006) and Louisiana (1964-1967 & 2001-2009). These programs successfully restored bears to portions of Louisiana and Arkansas, and, as populations in Arkansas began dispersing, to Oklahoma. In contrast, east Texas remains unoccupied despite the existence of suitable habitat in the region. To facilitate the establishment of a breeding population in east Texas, I sought to identify suitable habitat which bears could use for dispersal between known bear locations in Louisiana, Arkansas and Oklahoma and the east Texas recovery units. I utilized Maxent, a machine learning software, to model habitat suitability in this region. I collected known black bear presence locations (n=18,241) from state agencies in Louisiana, Oklahoma, Arkansas and east Texas and filtered them to reduce spatial autocorrelation (n=664). I also collected spatial data sets based on known black bear ecology to serve as environmental predictor variables. The model was developed at 30-m resolution and encompassed 417,076 km 2. The final model was selected to minimize model over-fitting while maintaining a high test Area Under the Receiver Operating Curve (AUC TEST)score. For final model interpretation and analysis, I used the 10th percentile training threshold available in Maxent which excludes the lowest 10% of predicted presence suitability scores from the binary predictive map, thus resulting in a more conservative predictive map. The final 10th percentile model predicted 43.7% of the pixels in the study area as suitable and 53.7 % percent of the pixels identified as potential recovery units by Kaminski et al. (2013, 2014) as suitable. To focus management efforts, I identified three movement zones with a high proportion of suitable habitat within which connectivity analyses were performed. Suitable patches greater than or equal to 12 km2 were classified within ArcGIS as stepping stone patches. Buffers of 3,500 m were generated around these patches to determine the level of functional connectivity in each zone. The final Maxent model confirmed that suitable bear habitat exists between source populations and the east Texas recovery units. The importance of percent of mast producing forest, percentage of cultivated crops and percentage of protected lands reflect what is known about basic bear biology and ecology. Furthermore, 153 stepping stone patches were identified within the movement zones, demonstrating that there is a reasonable chance of bears naturally dispersing to east Texas using the habitat identified in this study. Thus, protection of existing bear habitat and the stepping stone patches identified in this study should be a priority for managers seeking to facilitate natural bear recolonization of east Texas

    A Comparison of the Financial Reporting Standards of the United States and Germany

    German companies are having difficulties translating financial statements from German accounting standards to United States Generally Accepted Accounting Standards in order to trade stock on United States stock exchanges. The German accounting standards are compared with US GAAP in ten main areas of financial statement accounting. Microsoft financial statements in both US and German accounting standards are studied as an example of the differences between the two sets of accounting standards. Two areas of accounting are found to be of significant difference. Pension and depreciation expense would have to be adjusted to follow US GAAP before German companies could translate financial statements to US GAAP.B.S. (Bachelor of Science

    The Southern Historical Collection and Civil War and Reconstruction History: A Past and a Future

    Paper on how Southern Historical Collection has "advanced the study of the South but not always in the manner [J. G. de Roulhac Hamilton, its founder] had in mind." Materials gathered to support Hamilton's historical perspective remain vital to the posing of new questions about the Civil War and Reconstruction South. Presented at Southern Sources: A Symposium Celebrating Seventy-Five Years of the Southern Historical Collection, 18-19 March 2005 in the Wilson Library at the University of North Carolina at Chapel Hill

    The Effect of the Private Classroom Blog on the Acquisition of Formal Writing Proficiency with Spanish III High School Students

    Get PDF
    This study examined the impact of a private classroom blog implemented as an instructional technology on student writing proficiency in a world language with the focus on formal writing. The nonequivalent control-group, pre-posttest design was used to determine if the use of the private classroom blog in teaching world language formal writing affected student writing proficiency with the specific focus on task completion, comprehensibility, level of discourse, vocabulary, and language control. This research study used a convenience sample of sophomore, junior, and senior students in a Georgia public high school. Independent raters evaluated students\u27 writings using the Fairfax County Public Schools writing analytic rubric for level three. The researcher used ANCOVA to compare the posttest mean of the experimental group to the posttest mean of the control group in each category. No statistically significant differences were found between the two groups in any of the categories. Study limitations are outlined and suggestions for future research are included

    Computing on the Scaffolds: The Coming Transformation of Architecture and Construction with Digital Technologies

    Get PDF
    We are at the dawn of a digital age in architecture and construction, one of the world\u27s largest industries, and the architect Frank O. Gehry is leading that transformation. The Experience Music Project in Seattle is a recent and advanced example of the undulating forms and complex surfaces made possible by his use of three-dimensional digital representations. Bringing computing to the scaffolds promises to change the work practices, organizational structures, and productivity of all of the actors involved in construction projects, including architects, contractors, subcontractors, and labor groups. This panel will bring together Frank Gehry\u27s senior partner along with a specialty contractor who has worked on many Gehry buildings with two academics who have extensive backgrounds in technological innovations and industrial transformations. The questions they will address are: • What forces will drive versus inhibit this digital transformation? • What changes in organization structures will be required? • What challenges and opportunities will labor experience? • What actions and policies will help bring fruition to the promised benefits of computing on the scaffolds
