Measurement Of The Cross-Sectional Area Of The Nasal Passages Of Nine Species Of Modern Odontoceti With Implications For Comparative Physiology And The Paleophysiology Of The Dinosauria, Eric Paul Katz

Dissertations and Theses

In search of evidence for or against the endothermic dinosaur hypothesis, a recent study by Ruben et al. (1996) revealed that endotherms tend to have larger nasal cross-sectional areas than ectotherms of the same mass. The reason offered for this observation was that larger nasal passages are needed to house the complex respiratory turbinates possessed by endotherms. Whales were excluded from the study on the grounds that they have no nasal turbinates. In the present study, the cross-sectional area of the nasal passages of nine species of Odontoceti were measured by the use of latex casts. The regression of log …

Globalization And The Sustainability Of Human Health: An Ecological Perspective, Robert Costanza, A. J. Mcmichael, Bert Bolin, Gretchen C. Daily, Carl Folke, Kerstin Lindahl-Kiessling, Elisabet Lindgren, Bo Niklasson

Institute for Sustainable Solutions Publications and Presentations

The last half-century has seen momentous and accelerating changes in humankind's economic activities, political relations, and social and demographic profile. A prominent feature of this change is the increasing scale of human impact on Earth's natural biophysical systems: the climate system, stratospheric ozone, biodiversity, terrestrial and marine food-producing ecosystems, and the great cycles of water, nitrogen, and sulfur (Meyer 1996, Vitousek et al. 1997). These systems sustain the conditions on which life depends, and their weakening may therefore have profound long-term implications for human population health (McMichael 1993, Last 1997).

Developmental Trajectories Of Disruptive Behavior Problems In Preschool Children Of Adolescent Mothers, Susan J. Spieker, Nancy C. Larson, Steven M. Lewis, Thomas E. Keller, Lewayne D. Gilchrist

School of Social Work Faculty Publications and Presentations

Using hierarchical linear (HLM), we analyzed individual developmental trajectories of disruptive behavior problems between ages 3.5 to 6.0 years for 183 children of adolescent mothers. We examined how the level of problem behavior (intercept) and the rate of change over time (slope) are influenced by child's sex, mother's depression/anxiety symptoms, and mother's use of negative control for regulating child behavior. On average, disruptive behavior decreased from age 3.5 to 6.0. Child sex and maternal depression/anxiety related to the level of behavior problems but not to the rate of change. Boys and children of more depressed/ anxious mothers exhibited higher levels …

The Effects Of Mentoring On Work-Parenting Gains And Strains In A Sample Of Employed Predominately Female Afdc Recipients, Charlene Rhyne

Dissertations and Theses

Nationally, as well as locally, the emphasis in public assistance is to assist clients in becoming job ready. To this end, Oregon received waivers necessary to implement an innovative welfare reform effort, JOBS Plus Program (JPP), in 1994. The JPP provided subsidized employment for welfare recipients through the cashing out of public assistance benefits and Food Stamp monies. Employers were required to provide an on-site mentor for subsidized employees as a condition of agreement to participate in the Program.

Mentoring has been shown to positively impact employee overall job satisfaction, tenure, salary and promotion. While mentoring has been seen traditionally …

“Wars Of The Three Margarets”: Women In The Wars Of The Roses, Barbara Jean Traver

Dissertations and Theses

No study has yet examined the role of elite women in the Wars of the Roses. However, an explanation of their motivations and actions is crucial to understanding these conflicts.

Aristocratic women exercised considerable power under the system of "bastard feudalism." Women built and maintained affinities, acquired and defended land, used and manipulated the law, and influenced local politics. They had acknowledged roles as peacemakers and knew how to defend a castle. During the Wars of the Roses women would make use of all of these tools.

Three women played such an important role in these conflicts that they might …

Holgate Lake Study: An Examination Of The Issues Associated With Groundwater Flooding, John J. Lynch Jr., Heidi A. Mader, Mark Mccann

Master of Urban and Regional Planning Workshop Projects

This project examines Holgate Lake. Despite its natural hazard characteristics, the Holgate Lake area has not been immune to development pressure. Holgate Lake is an intermittent water body that forms when groundwater levels rise. Historical accounts show that the lake has formed at many different times in the last century. Because the lake fluctuates with the groundwater level, it is not necessarily present from year to year. As the area has developed, more and more people built in the location of the natural lakebed when the water was not present. When the lake level returned in the 1960's flooding of …

Internal Temperature Of Douglas-Fir Buds Is Altered At Elevated Temperature, Martha E. Apple, Melissa S. Lucash, David M. Olszyk, David T. Tingey, Donald L. Phillips

Environmental Science and Management Faculty Publications and Presentations

Pseudotsuga menziesii (Douglas-fir) saplings were grown in sun-lit controlled environment chambers at ambient or elevated (4°C above ambient) temperature. We measured internal temperatures of vegetative buds with thermocouple probes and compared temperatures of normal buds and abnormal buds with loosened, rosetted outer scales in elevated temperature chambers. The abnormal buds had higher and earlier peak daily temperatures than normal buds. Elevated temperature may influence the internal temperature of buds and contribute to the development of abnormal, rosetted buds with loosened outer scales. Abnormal bud development may alter branching patterns and allometry of Douglas-fir trees subjected to climatic change.

Voices Of Our Past: The Rank And File Movement In Social Work, 1931-1950, Richard William Hunter

Dissertations and Theses

During the period of the late 1920s through the late 1940s, a most remarkable event in the history of American social work emerged: the development of a vital radical trade union organizing effort known as the ''rank and file movement." Born within the growing economic crisis of the 1920s and maturing in the national economic collapse and social upheaval heralded by the Great Depression, the rank and file movement would attract the support and membership of thousands of professional social workers and uncredentialed relief workers in efforts to organize social service workers along the lines of industrial unionism. Within its …

1998 Oregon Population Report, Barry Edmonston, George C. Hough Jr., Jin Cheol Jo

Oregon Population Estimates and Reports

Oregon's population grew at an average annual rate of 1.81 percent during the 1990 to 1998 period. The total population increased by 425,000 during the eight-year period, reaching a population of 3,267,550 on July 1, 1998. Current annual rates of growth are above the U.S. national average of 1.04 percent.

Most of the way through the 1990s, the Oregon counties experiencing the fastest average growth rates are located along the 1-5 corridor and in central Oregon. The 1-5 counties include the area in the Willamette Valley and several areas in southern Oregon. The central Oregon counties are located along the …

Anne Frank: From Shared Experiences To A Posthumous Literary Bond, Laureen Nussbaum

World Languages and Literatures Faculty Publications and Presentations

Anne Frank is the best known victim of the Nazis, the representative of all the Jewish children murdered by them. She has become an icon, the heroine of a romanticized play and a subsequent film that made her name a household word all over the world and, at least in this country, the object of heated debates about her putative Jewishness or the lack thereof. While she has risen to fame as a symbol, her talent and her aspirations as a writer have generally not been taken seriously. However, the editor of a recent anthology, Women Writing in Dutch, published …

Improvements In Modeling Dissolved Oxygen In Activated Sludge Systems, Jacek Makinia, Scott A. Wells

Civil and Environmental Engineering Faculty Publications and Presentations

The aim of this research was to show the impact of the flow conditions and variations in the aeration intensity on changes in the predicted dissolved oxygen (DO) concentrations in a full-scale activated sludge reactor. The Activated Sludge Model No. 1 was used to describe the biochemical processes. The studies were performed at the Rock Creek wastewater treatment plant in Hillsboro, OR (USA). The simulation results were compared with data originating from two 24-hour experiments. The model that best reflected the spatial and diurnal distributions of the DO concentrations was the one-dimensional advection-dispersion equation with a variable overall oxygen mass …

Soliton Stability In A Z (2) Field Theory, J. J. P. Veerman, D. Bazeia, Fernando Moraes

Mathematics and Statistics Faculty Publications and Presentations

We investigate the stability of the coupled soliton solutions of a two-component Z(2) vector fieldmodel, in contraposition to similar solutions of a Z(2)×Z(2)model recently introduced. We demonstrate that the coupled soliton solutions of the Z(2) model are classically unstable.

A Comparison Of Efficiency Measurement Using Data Envelopment Analysis And Regression In The Utility Industry, Janice Forrester, Timothy R. Anderson

Engineering and Technology Management Faculty Publications and Presentations

It is the intent of this paper to discuss the theoretical differences between the manner in which regression and data envelopment analysis (DEA) separate variation into that which is caused by noise and that caused by inefficiency. It examines the empirical results of independent studies, one that used regression and one that used DEA. The studies were performed one year apart by independent teams using the same data and responding to the same questions. Both studies focus on monitoring the efficiency of the electric utility providers in light of deregulation

Geometrical Models For Grain Dynamics, Giovani L. Vasconcelos, J. J. P. Veerman

Mathematics and Statistics Faculty Publications and Presentations

We study models for the gravity-driven, dissipative motion of a single grain on an inclined rough surface. Imposing some conditions on the momentum loss due to the collisions between the particle and the surface, we arrive at a class of models in which the grain dynamics is described by one-dimensional maps. The dynamics of these maps is studied in detail. We prove the existence of various dynamical phases and show that the presence of these phases is independent of the restitution law (within the class considered).

Geometrical Model For A Particle On A Rough Inclined Surface, Giovani L. Vasconcelos, J. J. P. Veerman

Mathematics and Statistics Faculty Publications and Presentations

A simple geometrical model is presented for the gravity-driven motion of a single particle on a rough inclined surface. Adopting a simple restitution law for the collisions between the particle and the surface, we arrive at a model in which the dynamics is described by a one-dimensional map. This map is studied in detail and it is shown to exhibit several dynamical regimes (steady state, chaotic behavior, and accelerated motion) as the model parameters vary. A phase diagram showing the corresponding domain of existence for these regimes is presented. The model is also found to be in good qualitative agreement …

Is There Still A Need For The Special Assessment Program Within Oregon's Current Land-Use System?, David R. Brooks

Center for Urban Studies Publications and Reports

Based on the research completed to date regarding the various components of the Oregon farmland preservation program, one question begs to be asked: "Is there still a need for the Special Assessment Program within Oregon's current land use planning system?"

This paper is an attempt to assess the role of the Special Assessment Program in the context of the overall land use planning system in Oregon. It is my contention that the Special Assessment Program no longer plays a meaningful role in the movement to preserve land in the rural areas of the state. Also, it may actually have perverse …
