Evaluating the relative influences of positive and negative interactions in shaping communities is a major topic in modern ecology. Facilitative interactions between basal species are important in habitats with intense predation pressure or severe abiotic stresses. However, few studies address the potential for positive interactions between trophic levels to influence...
This is a study of the representations of prostitutes and prostitution produced within a particular historical framework-regulationism. Drawing support from public health movements, campaigns against depopulation and degeneration and protest from feminists and socialists, the "French system" of regulation of prostitution occupied center stage in social debates from the mid-nineteenth...
The purpose of this study was to determine whether a course in cultural competency would impact associate degree nursing students' perceptions of their abilities to provide care to culturally diverse clients. Ethnographic interviews with nursing faculty, graduates and students were utilized in course development. The cultural competency course was evaluated...
The graduate student population has been traditionally overlooked within higher education. However, within recent decades, much research has been devoted to addressing the multiple facets of the graduate student experience, including that of the graduate teaching assistant (GTA) position. This thesis seeks to explore in depth the experiences of GTAs...
In Oregon, property tax revolts and school equalization measures have led to increasingly unstable and more non-discretionary public funding for schools. As a result, public schools are turning to private donations to provide both basic and supplemental educational opportunities. Some schools and districts are raising hundreds of thousands of dollars,...
The purpose of this dissertation was to explore the experience of gifted girls transitioning from elementary school to sixth and seventh grade. The current counseling literature in this area found that gifted girls often struggle emotionally when transitioning to sixth and seventh grade. The bulk of this literature was based...
The growth of foster care, particularly kin foster care has greatly outpaced our knowledge. The purpose of this exploratory qualitative study was to develop a more informed understanding of foster family functioning from the perspective of foster parents. This study examined the experiences of 9 kin and 12 nonkin foster...
Research relying on remotely sensed data on land use and deforestation has exploded in recent years. While satellite-based measures have clear advantages in terms of coverage, the presence of measurement error within these products is often overlooked. Here, we detail the econometric implications of these errors when analyzing the determinants...
Weed management is one of the main challenges for organic agriculture. Soil solarization has been shown to be an effective mitigation strategy for weeds and soil borne plant pathogens but few studies have been conducted in cooler climates such as the Pacific Northwest.
Horticultural nurseries are heterogeneous and spatially complex agricultural systems, which present formidable challenges to management of diseases and pests. Moreover, nursery plants shipped interstate and internationally can serve as important vectors for pathogens and pests that threaten both agriculture and forestry. Current regulatory strategies to prevent this movement of pathogens...
