Raising fragile : the experiences & perspectives of the families of male Fragile X individuals Shorb, JoAnne E. The purpose of this qualitative research study was to address the experiences and perspectives of those who have grown up with and raised males who have Fragile X syndrome. The methods used in the study included surveying and interviewing the family members of adult individuals with Fragile X, reviewing resources for Fragile individuals entering adulthood, and researching existing data and the memoirs of other families who have experienced the fragile cycle and lifestyle. This study resulted in many families coming forward, expressing their thanks for attempting to identify resources for fragile families, as well as expressing interest in participating in the study. Findings resulted in shared memories of joyous times spent with the "proverbial child" of the households interviewed, as well as reflections upon difficult experiences laced with seizures, fits of rage, and loss. The families interviewed bared their souls in hopes to provide insight, hope, and forethought to families who either are, or have yet to begin the journey of helping a fragile loved one enter adulthood.

Physiological impacts of groundwater and surface water application on desert graminoids of different geographic origin Abdallah, Mohamed (Mohamed Ahmed B.) Desert plant communities are among the most sensitive to changes in soil water conditions. In areas with shallow aquifers, it is important to understand both the effects of groundwater alterations on vegetation and how changes in surface-soil water affect plant water uptake. Studies in arid environments have evaluated the effect of groundwater variation and simulated precipitation on plant production and vegetation condition but it is not clear if plants respond equally to the availability of surface water or groundwater. This study was conducted in a greenhouse to evaluate growth and physiology of three desert graminoids (Distichlis spicata, Leymus triticoides, and Juncus arcticus) as affected by surface water availability (mimicking precipitation) or subsurface water availability (mimicking groundwater). The species of study are amply distributed in wetlands and open rangelands of western USA and were collected from two sources of ecological distribution: an area near Bishop, California, and an area near Burns, Oregon. The Bishop, California area has a characteristic shallow aquifer and plants in this area are considered somewhat dependent on groundwater. The Burns, Oregon, area sustains the same species but in a variety of soil moisture conditions. We had two general hypotheses for this study: 1) that the use of surface water is favored over groundwater and 2) that there are ecotypic differences in the response of the species to water availability. The first hypothesis was partially supported by the results of the study, but variability existed among species. However, when all species had equal access to both surface soil water and groundwater plants tended to preferentially use surface water. The second hypothesis was clearly supported by our results. Although the mechanism is not clear, it is possible that an area with periodic and predictable shallow groundwater underlying a dry or saline soil layer, such as the California site, might favor plant ecotypes with high proficiency in water acquisition by deeper roots. Knowledge of water use characteristics of vegetation is essential to provide management guidelines for areas where plants depend on both surface-soil water and groundwater. This study contributed to that knowledge. Further studies on ecotypic variation and an expansion to different species that inhabit areas with shallow aquifers are recommended. Graduation date: 2013

Changing student learning approaches in fundamental accounting education through the use of graphic organizers Fisher, Paul A. (Paul Anthony) The field of accounting has experienced dramatic changes in the past 20 years. Advances in technology and workplace requirements have changed the responsibilities in the accounting position of a historical recorder to a functioning manager within the organization. The curriculum used by accounting instructors has not changed or kept pace with redefinition of accounting competency. This study was designed to measure the effectiveness of graphical organizers in teaching accounting. Assessment was based on a deep versus surface approach checklist which was altered to reflect accounting terminology. Means testing was the primary comparison protocol. Two classes were selected in an Oregon community college which were instructed by the same instructor. One class used graphic organizers as a communication tool, and the other class did not. Results did not indicate or favor one method over the other. Other learning factors contributed to the lack of significance in this study. Graduation date: 2013
