In order to develop effective interventions designed to encourage more
middle-aged individuals to engage in regular exercise, there is a need to
further understand the mechanisms involved in the decision to exercise.
One appropriate conceptual framework involves future-oriented self-conceptions,
or possible selves (Markus & Nurius, 1986). Possible selves, both
hoped-for...
Mutations to superoxide dismutase were the first proven cause of Lou
Gehrig’s disease (amyotrophic lateral sclerosis; ALS) implicating superoxide in
the selective death of motor neurons that characterizes ALS. Nitric oxide
competes effectively with superoxide dismutase for superoxide to form the
powerful oxidant peroxynitrite. Endogenous formation of peroxynitrite can kill...
American meteorology was synonymous with subjective weather forecasting in the early twentieth century. Controlled by the Weather Bureau and with no academic programs of its own, the few hundred extant meteorologists had no standing in the scientific community. Until the American Meteorological Society was founded in 1919, meteorologists had no...
The major thrust of this research was to design, test, and
perfect an accurate and effective assessment technique, which would
result in becoming an assessment model. For the purpose of developing
this assessment model, the employment need for full-time
instructors of occupational subjects in the community colleges within
the state...
A regime-switching model for market integration study is extended to incorporate dynamic trade flow information and risk perceptions based on an expected utility framework. An application of the extended model to the US-China soybean markets analysis shows that: One, the positive arbitrage rent uncounted-for in the extended model has been...
A thermomechanical pulp, a high yield sulfite pulp, and a high yield solvent sulfite pulp from western hemlock [Tsuga heterophylla (Raf.) Sarg.] wood were investigated to determine the amount of carbohydrate material present and to elucidate the structures of the carbohydrates. The effects of the three pulping processes, which were...
The purposes of this investigation were twofold:
1. To determine important criteria for making a selection of
course content in general biology.
2. To ascertain what should be the content emphasis in
biology for the purposes of general education at the freshman
college level.
The literature pertinent to the problem...
Karl Jordan (1861-1959) was an extraordinarily productive entomologist who influenced the development of systematics, entomology, and naturalists' theoretical framework as well as their practice. He has been a figure in existing accounts of the naturalist tradition between 1890 and 1940 that have defended the relative contribution of naturalists to the...
Four aspects of factors influencing the accuracy of nondestructive chlorophyll (Chl) and nitrogen (N) measurement in fresh leaves were studied: (1) optimum wavelength (OW) identification; (2) indices development and evaluation; (3) influence of leaf properties; and (4) influence of meter parameters and sampling technique. Results were used to develop indices...
This research project is an historical case study of the conflict
which evolved from the deliberations and subsequent implementation
of bilingual education in Central School District 13J, Independence,
Oregon. The time period under consideration spans 35 months,
beginning in August 1974, when district officials first proposed bilingual
education, and ending...
The development of new technologies in science is a balance between existence and use. There are three versions of this duality – something is built and users come, something is built and users don’t come, and, finally, potential users show up but the ballpark has not yet been built. In...
There is a knowledge gap concerning the outcomes of early adolescent sexual initiation (ASI). In particular, the influence of early ASI upon adult attachment is unknown. A multiple regression study was conducted to address this knowledge gap. Adult partner/spouse attachment was the criterion variable, and the predictor variables included both...
Contracting nucleolar vacuoles are a general and consistent
feature of somatic tobacco cells growing in microcultures. Nucleolar
vacuoles were studied in cells from callus tissues of two
single-cell clones, H-196 and H-239, of hybrid tobacco (Nicotiana
tabacum X N. glutinosa). Vacuoles periodically contracted either
completely or incompletely, apparently releasing a...
The majority of teachers in the state of Oregon are White, prompting the state’s legislative bodies to explore and create ways to increase racial diversity in the profession. Contextually, both state level mandates and national accreditation bodies have attempted to address the lack of diversity amongst teachers in the K-12...
Currently, the temporal arc distribution across the ingot during the vacuum arc remelting (VAR) process is not a known or monitored parameter. It is has previously been shown that arcs can spatially constrict during VAR, and this constriction can lead to undesired defects in the material. Additionally, correct accounting for...
Irradiation of a tryptamine linked through its side-chain nitrogen to an alkylidene malonate residue results in an intramolecular [2 + 2] cycloaddition to the indole 2,3-double bond. The resultant cyclobutane undergoes spontaneous retro-Mannich fission to produce a spiro[indoline-3,3-pyrrolenine] with relative configuration defined by the orientation of substituents in the transient...
