Additional research on propulsion airframe interaction (PAI) with trailing edge flaps at low Reynolds numbers was necessary to advance the...
Microhabitat use by adult speckled dace (Rhinichthys
osculus), adult longnose dace (R. cataractae), and
juvenile dace (R. spp.) was investigated during the summer
of 1992 in an Oregon Cascades stream. Selected areas were
snorkeled day and night in order to evaluate differential
use of habitat resources both temporally and spatially....
The Pacific Northwest has a relatively low diversity of primary freshwater fishes with most of the endemism and diversity in the Columbia River and Klamath River. However, the Oregon Coastal Subprovince defined as the coastal rivers from Miami River in the north to Sixes River in the south, has a...
There are three recognized species of Siphateles from the Great Basin; S. alvordensis, S. boraxobius and the tui chub, S. bicolor. One species, S. boraxobius, is endangered and one population of tui chub at Hutton Spring is threatened. Despite several morphological and molecular studies, the taxonomy and relationships of tui...
Eliminating physical activity disparities among ethnic minorities in the U.S. is important. Cultural differences have been found to be plausible contributing factors associated with such disparities. Therefore it is important to investigate and understand the mechanisms by which diverse aspects of cultural experiences affect physical activity participation among ethnic minorities,...

The grid geometry plays a vital role in the performance of gridded ion thrusters. It can dramatically impact the erosion rate and thrust. Designers push the limits of electric in-space propulsion by optimizing grid parameters through simulation. At the same time, computational models of plasma physics are intensive. A baseline...
Despite the now common usage of the term “girl”, there has been little call for pause and deeper analysis into what we actually mean when we use this term. In particular, animated film provides a wide scope of media texts that claim to focus on girlhood; but how do we...
A recipe as a piece of text can tell a variety of stories as well as any other. Using a feminist rhetorical analysis, I read my grandmother’s personal recipe journal to show that her writings contain valuable information about women’s lives in twentieth century Poland. Through the close examination of...
This study looks at how gendered language circulates affect in order to coerce gender binary conformity. I analyze the ways gendered phrases like “sit like a lady”, “don’t be a bitch”, and “man up” communicate binary gender expectations within a U.S. context, and what they have to do with larger...

Size-structured spatial patterns in larvae of 2 sucker and 3 minnow species are described from fixed-site
sampling in Upper Klamath Lake, Oregon, and are used to demonstrate patterns of size-based losses downstream and
retention in the lake. The smallest larvae of shortnose suckers (Chasmistes brevirostris), Lost River suckers (Deltistes
luxatus),...
This case study examines the Upper Klamath Basin of Oregon, which is experiencing a water crisis due to over-allocation. The purpose of this case study is to identify land cover / land use change looking specifically at wetland conversion and to discussion the effects of wetland loss on ecosystem services....
Distribution and juvenile habitat use of bull trout (Salvelinus
confluentus) were surveyed in selected areas of the Upper Willamette,
Deschutes, upper Yakima, and upper Cedar River basins in Oregon and
Washington from 1989 to 1991, using day snorkeling, night snorkeling,
and electrofishing. These methods were selected after a preliminary
diel...
Processes of metamorphosis, settlement, and growth were examined in Pacific sanddab
using field studies and otolith microstructure. This flatfish transforms at large sizes, has a
gradual metamorphosis, and settles to a nursery on the middle continental shelf. Eye migration
takes 3 months and "metamorphosis proper" which begins after completion of...
Demographic characteristics of juvenile Dover sole
(Microstomus pacificus) were examined in relation to
physical and biotic factors to develop a hypothesis
explaining annual variations in recruitment. Surveys were
conducted along the Oregon continental shelf at depths
between 50-400 m bimonthly during 1989 and annually (in
March) between 1990 and 1993....
The composition and distribution of fish assemblages was examined in a
floodplain lake system in the Amazon basin. Quantitative samples were
collected during the 1992-1993 flooding season at Marchantaria Island, Solimoes
River. A total of 25,819 specimens representing 8 orders, 30 families, 101
genera and 139 species of fish were...
Low copy number anonymous nuclear loci were used to search for species markers in four species of Klamath Basin suckers. We sequenced 28 randomly chosen loci representing 10,421 bp; 21 loci were similar to sequences in GenBank. Eight fixed sequence differences were found among Klamath species. Locus 120 contained rare...
Hypotheses of phylogenetic and historical zoogeographic relationships of glyptocephalines (Glyptocephalus cynoglossus, G. zachirus, G. stelleri, Microstomus kitt, H. pacificus, H. achne,
Embassichthys bathybius, and Tanakius kitaharae) were constructed based on comparative anatomy and external morphology. The phylogenetic approach was cladistic and character polarity was
determined by using out-group comparison. One...
The Oregon chub. Oregonichthys crameri. one of
Oregon's endemic freshwater fishes. is restricted to the
Willamette and Umpqua rivers and their tributaries.
Specimens from the two rivers have traditionally been
considered the same species. The goal of this study was to
re-examine that assumption and determine if the Willamette
Oregon...
Upper Klamath Lake in southern Oregon has two species of lacustrine suckers,
Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris that
were historically abundant. Results of surveys performed in the mid-1980's indicated that populations of both species were declining and ageing with apparent recruitment failure in most years...
The early life history stages and metamorphosis in Dover
sole (Microstomus pacificus) are described from 201 larvae and
juveniles. Unlike other pleuronectids, with the possible exception
of the deep-sea sole (Embassichthvs bathvbius), initial migration of
the left eye is not associated with metamorphosis or transition from
plankton to benthos. The...
Recently, there has been concern over the decline of the Pacific lamprey, Lampetra tridentata, in the northwestern United States. However, effective management has been impeded by data gaps in basic biology, especially in the early life stages. Consequently, in 2004 and 2005 I examined reproductive ecology, larval recruitment, and lamprey...
Field collections in the Southern Gulf of Oman and the Northwestern Arabian Sea, and
examination of museum collections from this study area, yielded 7 genera and 33 species
of apogonid fishes. Twenty one species of Apogon, one Archamia, four Cheilodipterus,
three Fowleria, one Rhabdamia, two Siphamia, and one Holapogon are...
I studied the occurrence of two sympatric morphs of arctic charr, Salvelinus
alpinus (L.) in Vatnshlidarvatn, a small shallow lake in NW Iceland. The arctic charr
were subjectively distinguished by colour and appearance as brown morph or silver
morph, and measured for morphological and life history characters. The study
revealed...
The Antarctic contribution to sea level is a balance between ice loss along the margin and accumulation in the interior. Accumulation records for the past few decades are noisy and show inconsistent relationships with temperature. We investigate the relationship between accumulation and temperature for the past 31 ka using high-resolution records...

With the growing popularity of kinesiology at the undergraduate level, one would expect the field to be influential. Kinesiology, however, appears to be in a paradox. The undergraduate popularity is not reflected in the rest of academia, or even the general public, many of whom feel kinesiology is not a...
The ongoing worldwide loss of biodiversity has been described as a "biodiversity crisis," "the Anthropocene defaunation," and alternatively "an extinction spasm." More recently, many scientists have come to the conclusion that we are witnesses to Earth's sixth major mass extinction event, which has the potential to fundamentally alter basic ecological...
The eruptive history of the Quaternary Cascades arc has been relatively well characterized. However, much less is known about the frequency and sizes of explosive eruptions produced by earlier stages of the arc. The Late Neogene Deschutes Formation of Central Oregon preserves a remarkable record of heightened pyroclastic activity during...
There has been concern voiced for a number of years about the problem of program plagiarism. A number of SIGCSE Bulletin articles have discussed the issue. However, it is not at all clear as to what behavior we are actually referring, nor to what extent it is occurring. How do...
Two studies were undertaken in search of a method or methods which might improve the survival of planted Douglas-fir seedlings on severe sites. The first, or preliminary study involved the planting of 2-0 Douglas-fir seedlings on southerly aspects, using nine techniques, including a control. The second, or main study involving...
Chinese international students in American colleges and universities report low levels of physical activity involvement, which may limit them in terms of

The overarching premise of this dissertation is to understand how different college and university physical activity education policies affect college and university students. Fundamentally, some American colleges and universities require their students to complete a physical activity education requirement whereas others do not. Given the different policy arrangements of college...
Through this dissertation, the quality of freely available physical activity promotion web articles that lay adults would likely locate online was critically appraised and theoretically analyzed. Three broad categories were considered. They were 1) message consistency with national health guidelines for physical activity; 2) suitability for health-related communication; and 3)...
Purpose
To provide an update on the amount and type of physical activity education that occurs in medical education in the United States.
Methods
All accredited doctor of medicine (M.D., n = 141) and doctor of osteopathic medicine (D.O., n = 29) institutions were reviewed using their publicly accessible websites....
This was a cross-cultural comparative study that examined college students' physical activity behavior in both the United States and the Republic of China on the basis of the full Transtheoretical Model (TTM) of behavior change. Although current investigations do support TTM as a powerful model of physical activity behavior change,...
Supervised exercise interventions can elicit numerous positive health outcomes in
breast cancer survivors. However, to maintain these benefits, exercise needs to
continue long after the supervised program. This may be difficult, as in this
transitional period (i.e., time period immediately following a supervised exercise
program), breast cancer survivors are in...
Design is a process of decision making. Organizations that are dedicated to systematic support of the design process tend to have higher profit margins. Further, studies of system development have shown that early-stage design mistakes have a large impact on incurred costs. Therefore, it is critical to identify methods to...
Properly written waiver of liability forms can be an effective tool in decreasing injury liability of intramural and recreational sports programs. In order for a waiver to be effective, (i.e., held up in court), participants must not only read and sign the waiver, but they must understand it as well....
Upon the annex of Lithuania as a Soviet state, the Soviet Union imposed an order
on Lithuanian athletic figures to represent the Soviet Union. Lithuanian athletes would
now be obligated to represent the Soviet Union in all international sporting events in
which they competed. The international success of Soviet Athletes,...
Purpose: Increasing enrollment numbers of multicultural students, and growing research between the relationship between student engagement and student success and retention heighten the importance of addressing student engagement in campus recreation. This study was conducted to explore the facilitators and barriers to underserved students participating in physical activity through campus...
Offering courses that promote, encourage, and support physical activity among college students has been an aim of physical education departments for the past century (Sargeant, 1900). Even so, this population has been identified in Healthy People 2010 as a target population segment in need of physical activity intervention. Historically, such...
Linear solvers are often used to solve neutron diffusion problems. These tools have two significant shortcomings. First, parallel implementations provide only a modest speedup. The operations cannot be divided cleanly between processors. Second, for large matrices they can be very slow. Our primary goal is to find a new method...
Tanoak (Lithocarpus densiflorus), along with some other members of Fagaceae, are susceptible to sudden oak death caused by the oomycete Phytophthora ramorum. Symptoms of the disease include dying crowns, bleeding cankers, and eventually death of infected trees. The cause of mortality is not well understood, but recent research indicates that...
After traveling to Africa and experiencing the struggles and confusion of interacting with a new culture, I saw the need for some sort of orientation device that would adequately prepare first timers, but also not be too lengthy and daunting for a person that will only be spending a few...
