A total of 44 intermittent sand filter-septic systems, in five counties of Western
Oregon, were sampled over a three-month period during the summer of 1995. The sand
filter systems varied in age from 36 months up to 167 months (3 to 13.9 years). Liquid
samples were taken from the septic...
The goal of this project is to recommend a broadly-acceptale efficient and effective methodology for characterizing streamside riparian attributes in forested settings at the site grain for regional monitoring. The authors consider monitoring design in the context of three interacting constraints: ecological functions, capabilities of technologies, and user needs. The...
The purpose of this investigation was to compare the effectiveness of integrated and segregated settings in elementary physical education. The efficacy of each setting was measured by the quantity of opportunities to respond (OTR) and the quality of those responses. This study examined the frequency and motor appropriateness of OTRs...
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...
In this paper, we consider the transfer of environmental and cultural assets to the next generation as a potential measure of sustainability. We define net assets as the value of renewable and nonrenewable natural resources plus human-made, intellectual, social, and cultural capital, minus any debts. We apply this approach by...
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...
It has been recognized since the 1950's that radioisotopic disequilibrium between naturally occurring parent-daughter isotope pairs in seawater can provide information on the rate of processes segregating them. In the surface ocean, the U-238:Th-234 parent-daughter pair tends to display measurable disequilibrium that is attributable to the effects of scavenging on...
The primary focus of this work is on examining structure-property relationships of interest for high-power nonlinear optical and laser crystals. An intuitive and simply illustrated method for assessing the nonlinear optical potential of structurally characterized noncentrosymmetric materials is introduced. This method is applied to materials including common quartz and tourmaline...
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...
