This study describes Extension field staff orientations toward
poverty. Expressions on origins, solutions and definitions of poverty
were elicited from informants. Responses were then classified by
categories, coded and analyzed using the Statistical Interactive Programming
System (SIPS). Orientations were then measured by identifying
modal categories. A category was identified as...
Crossmatings were accomplished among three semi-closed lines within a population of pigs, for the purpose of investigating effects of crossbreeding on reproductive traits. Two of the lines were purebred (Berkshire and Yorkshire); the third line ("Composite") consisted of descendants from inter se matings among offspring of crosses of the Berkshire...
Purpose of the Study
In most liberal arts colleges, the majority of students enrolled
are primarily interested in a liberal education. To meet the requirements
of its students, several colleges have introduced a relatively
new program in the sciences; this program is the integrated
science course. This study attempts to...
The objectives undertaken in this study were:
1) to develop means of identifying the immature stages of
the known insect predators and parasites of the Douglas-fir beetle; 2) to investigate the possible distribution,
spatially and/or temporal, of the known insect predators
and parasites in standing trees infested by the Douglas-fir...
The study resulted from a desire and interest to include computer
simulation techniques in the design of educational practices.
The purposes of the study were (1) to develop a computer model which
would simulate the service functions of a counseling center by tracing
students through the center and (2) to...
The incitant of Verticillium wilt of peppermint (Verticillium
dahliae Kleb.) causes disease symptoms only in the genera Mentha
(the mints) and Monarda. This fungus is unable to grow saprophytically
through natural soil. V. dahliae survives in soil by colonizing
and forming microsclerotia in susceptible plants, living root tissue
of many...
The treatment of waste water from a corn freezing process by
activated sludge with the aid of alum coagulation was investigated.
Both high and low energy level systems were observed with good
flocculation occurring at the low energy level. Because poor flocculation
occurs at high energy level conditions, alum was...
Shame is a debilitating inner experience elicited by the negative self-appraisal of one's entire self, and is characterized by a deep-seated sense of being flawed, defective, and therefore unworthy of acceptance and belonging (Brown, 2006). Although significant research has explored self-conscious emotions, including shame, little has been done to examine...
The purpose of this paper is the statement and examination of
relevant data pertaining to the subject of trans-Pacific pre-
Columbian contact. The paper's contents will be organized in to
five major areas: oceanography, ship building, archaeology, religion
and history, plus an introduction and conclusion. Each of
these chapters will...

The role of science in marine policy, and environmental policy in general, is a debated topic. Currently, there is an increasing desire for transparent and participatory democracy that involves more input from local residents and other non-experts. These demands often conflict with the increasing complexity of problems and the real...

Both Leperisinus oregonus and L. californicus are bark beetle
species which emerge from Fraxinus latifolia brood logs as sexually
immature adults and disperse to living ash. Occasional field observations suggest that, for overwintering and maturation feeding, L.
oregonus enter trunks and branches, whereas L.; californicus enter twig
crotches, buds and...
The island of Tahiti, the largest in French Polynesia, comprises two major volcanoes aligned NW-SE, parallel with the general trend of the Society Islands hotspot track. Rocks form this volcanic system are basalts transitional to tholeiites, alkali basalts, basanites, picrites, and evolved lavas. Through K-Ar radiometric dating we have established...
Thermochemical water splitting cycles have been conceptualized and researched for over half a century, yet to this day none are commercially viable. The heavily studied Sulfur-Iodine cycle has been stalled in the early development stage due to a difficult HI-H₂O separation step and material compatibility issues. In an effort to...
Cell-to-cell communication by chemical signals, termed quorum sensing (QS), is a common regulatory scheme in the microbial world. Pseudomonas aeruginosa¸ an opportunistic pathogen of burn wounds and cystic fibrosis lungs, uses QS to control the expression of hundreds of genes, particularly those necessary for population level benefits such as biofilm...
Over the past 60 years, housing growth has outpaced population growth
in the United States. Conservationists are concerned about the far-reaching environmental
impacts of housing development, particularly in rural areas. We use
clustering analysis to examine the pattern and distribution of housing development
since 1940 in and around the Northern...
Riparian ecosystems support mosaics of terrestrial and aquatic plant species that enhance regional biodiversity and provide important ecosystem services to humans. Species composition and the distribution of functional traits - traits that define species in terms of their ecological roles - within riparian plant communities are rapidly changing in response...
Why do rural households leave for urban places? And how does this
decision affect their economic well-being? Rural places in the United States have higher poverty and unemployment rates and lower levels of educational attainment relative to urban places. Does leaving a rural place for a city offer a pathway...
Knowledge of cloud and precipitation formation processes remains
incomplete, yet global precipitation is predominantly produced by
clouds containing the ice phase. Ice first forms in clouds warmer
than −36 °C on particles termed ice nuclei. We combine observations
from field studies over a 14-year period, from a variety of
locations...
The physical interpretation of simultaneous multiangle observations represents a relatively new approach to remote
sensing of terrestrial geophysical and biophysical parameters. Multiangle measurements enable retrieval of physical scene
characteristics, such as aerosol type, cloud morphology and height, and land cover (e.g., vegetation canopy type), providing
improved albedo accuracies as well...
The initiation of ice in an isolated orographic wave cloud was compared with expectations based on ice nucleating aerosol concentrations and with predictions from new ice nucleation parameterizations applied in a cloud parcel model. Measurements of ice crystal number concentrations were found to be in good agreement both with measured...
Cell death is a process of dying within biological cells that are ceasing to function. This process is essential in regulating organism development, tissue homeostasis, and to eliminate cells in the body that are irreparably damaged. In general, dysfunction in normal cellular death is tightly linked to cancer progression. Specifically,...
Subduction zone earthquake and tsunami hazards affect tens of millions worldwide and the recurrence of these disasters can be evaluated with paleoseismic techniques, because earthquake cycles (and their supercycles) typically span many millennia. In these three chapters, I discuss a suite of analyses I use to evaluate the sedimentary record...
