Riparian areas in the Pacific Northwest provide important biotic and abiotic
features, such as down wood, moist microsites, and abundant invertebrate prey that
benefit aquatic and terrestrial amphibians. Reported high densities of amphibians from
streams and riparian areas in the Pacific Northwest highlight their importance in riparian
food webs. Amphibians...
This study examined the relative contribution of parental warmth,
non-authoritarianism, and approval of sex-typed behavior to children's
sex role knowledge and preference. Subjects were 45 married
couples, and their 25 male and 20 female preschool children. Parental
attitudes toward child-rearing and sex role behavior were assessed
with the Parent Attitude...
This study examined channel structure and position and riparian
vegetation and land use on the upper 70 km of the McKenzie River, Oregon in
the 1940s, compared the 1940s conditions to present conditions, and explored
the processes driving change in this system and the implications for aquatic
habitat. The hydrologic...
This paper continues exploration in the area of
programming for parallel computers. The appendix to the
paper contains an extensive survey of the literature related
to parallel computers and parallel programming techniques.
The paper itself presents a new approach to solving
the Laplace equation on a. parallel computer. A new...
Rhizobium, in symbiotic association with leguminous plants, is able to fix atmospheric nitrogen after first forming root nodules. Since polyamines are associated with and found in high concentration in rapidly growing cells and are thought to be important for optimal cell growth, it is possible that these polycations are involved...
This survey looks at five different polygon breaking algorithms and compares them. The criteria for comparison are:
1. Complexity of the algorithm.
2. The number and type of subpolygons produced.
3. The classes of input polygons that can be broken.
The best algorithm is then coded and a comparison is...
This thesis documents a new language which facilitates
the construction of Turing machines. The language translator
is written in Compass and has been debugged and is
available for use on the CDC 3300.
This study concentrates on threshold values for the two most popular control flow metrics: McCabe's cyclomatic complexity and the knot count. We describe the results of an experimental study to empirically determine a threshold value for knot count for student programmers. The experiment was designed to measure the interaction between...
