An Integrated Approach To Acculturation: A Personal Journey, Douglas C. Stone

MA TESOL Collection

The intention of this professional paper is to propose a new, integrated model for acculturation which brings psychological understanding to this process. The first section of this paper gives a brief introduction and several necessary definitions. The second section introduces several existing acculturation models which I found applied to aspects of my experience, but which were inadequate in important areas. In the third diction I outlined a number of psychological models which I used to cope with acculturation and understand my experience before having contact with the acculturation material from the second section. In the fourth section I give an …

Introduction, Neil P. Bernstein

Journal of the Iowa Academy of Science: JIAS

In this issue, the Iowa Academy of Science honors three of our colleagues who passed away in 2000. Duane Isely, Larry Eilers, and George Knaphus shared many of the same interests. All three were botanists, although George's research on fungi and heterotrophic protistans relegated him to the botany departments only by default. However, more importantly, all three were teachers. I believe that one of the lessons that they would have taught was the need to carefully document present patterns if we are to understand the future. However, many biologists poorly support this concept today.

In Memoriam: Larry Eilers, Paul A. Christiansen

Journal of the Iowa Academy of Science: JIAS

Larry came to botany along an unusual route. His first college degree was in engineering. After a stint at secondary teaching Larry worked at Collins Radio in Cedar Rapids, then returned to UNI (SCI then) and took a master's degree in biology, He continued his study at the University of Iowa under Dr. Robert Thorne and took his Ph.D. in 1964. He did the flora of the Iowan Surface (the Iowan Drift in those days). He taught at Syracuse University and University of Indiana at Terra Haute before joining the faculty of the University of Northern Iowa.

Factors Associated With Occurrence And Density Of Wetland Birds In The Prairie Pothole Region Of Iowa, Steve E. Fairbairn, James J. Dinsmore

Journal of the Iowa Academy of Science: JIAS

Wetlands within wetland complexes in northwestern, north-central, and central Iowa were surveyed for bird use in 1997 and 1998. Species occurrence, species richness, and density of nesting species were related to wetland habitat variables. A habitat diversity index measuring the evenness of distribution of the different habitats within a wetland was the best predictor of species richness in both years. The habitat diversity index was also the best predictor of the occurrence of individual species in both 1997 and 1998. Eight of 11 species (7 3%) in 1997 and 13 of 18 species (72%) in 1998 had greater densities in …

Tests Of A Rotenone-Impregnated Bait For Controlling Common Carp, Joseph L. Bonneau, Dennis L. Scarnecchia

Journal of the Iowa Academy of Science: JIAS

An experimental rotenone-impregnated pelleted (approximately 10 mg/pellet) bait was tested in force-feeding and field-feeding experiments as a method of control for common carp (Cyprinus carpio). Mortality rates of force-fed fish ranged from less than 40% when fed one pellet to 100% when fed more than 10 pellets. Mortality occurred within 48 h. Mortality rates of control fish did not exceed 10%. In reservoir feeding trials in 1994 and 1995, carp were fed for 2-3 weeks on a non-toxic, vegetable-based bait dispensed by automatic feeders, followed by one feeding of the bait with rotenone added. Carp ceased feeding on the rotenone …

Recent Observations Of The Distribution And Status Of Bluntnose Darters And Crystal Darters In Iowa, Melvin C. Bowler

Journal of the Iowa Academy of Science: JIAS

The distribution and status of Iowa's fishes were last extensively described in Iowa Fish and Fishing (Harlan et al. 1987). Since then, numerous fish collections have been made in Iowa's interior and bordering rivers and streams. Excluding non-native species, there have been three documented accounts of new fish species distributional records in Iowa since 1987. In this paper, I describe new collections of crystal darter (Crystallaria asprella) and bluntnose darter (Etheostoma chlorosomum) from the Mississippi River. The first documented specimen of C. asprella in Iowa was collected in Pool 11 of the Upper Mississippi River (UMR) in 1995. One specimen …

Tillage Effect On Soil Water Content And Soybean (Glycine Max) Yield In A Strip Intercropping System, M. Ghaffarzadeh, F. Garcia Prechac, M. M. Harbur, R. M. Cruse

Journal of the Iowa Academy of Science: JIAS

Soybean [Glycine max (L.) Merr.] response to strip-intercropping with corn (Zea may L.) and oat (Avena Jativa L.) interseeded with nondormant alfalfa (Medicago Jativa L.) may be affected by soil moisture. A three-crop strip-intercropping system of corn, soybean and oat interseeded with nondormant alfalfa was established to determine the effect of tillage system and row position on soil water content and grain yield in the soybean strip. The experiment was a split-plot design with three tillage treatments (conventional, CT; reduced, RT; and minimum tillage, MT) as main plot effects and three row positions (both edge rows and the center …

Identification And Distribution Of The Treefrogs Hyla Versicolor And Hyla Chrysoscelis In Iowa, Catherine E. C. Oberfoell, James L. Christiansen

Journal of the Iowa Academy of Science: JIAS

Historically, the tetraploid and diploid species pair of gray treefrogs, Hyla versicolor and Hyla chrysoscelis, were mapped collectively in Iowa because no macroscopic morphological characteristics useful in recognizing the two species had been found. The present study reports identification and separation of the species by counts of nucleoli in the palpebral membrane of the eye and by measurement of scanning electron micrographs of toepad epithelial projections. Subsequent morphometric data confirm that the two species are morphologically distinct in Iowa but that overlap in characters continues to make macroscopic morphology unreliable for identifying individuals. H. chrysoscelis is distributed sporadically though all …

Low-Saturated-Fat Soybean Oil Reduces Saturated Fat In School Menus, J. M. Mahnken, S. F. Lutz, C. J. Anders, W. R. Fehr

Journal of the Iowa Academy of Science: JIAS

This study evaluated the impact of using low-saturated-fat soybean {Glycine max (L.) Merr.} oil on the saturated fat content of school menus. Seventy-six weekly menus were obtained from the Iowa Department of Education during School Meals Initiative reviews for the 1996-1997 school year. Three modifications were performed on school menus using the Nuttikids computer program: Low-saturated- fat (LSF) soybean oil replaced traditional vegetable oil in menu items; LSF soybean oil was substituted for traditional vegetable oil, solid fats, and egg yolks in recipes; and a menu simulation was conducted where oils and solid fats used in menu items were …

Species Specific Odds Of Occurrence Of Blackspot Among Fish From The Maple River In Western Iowa, John W. Mellen

Journal of the Iowa Academy of Science: JIAS

Odds ratio analysis was used to evaluate the relative likelihood of occurrence of blackspot (Neascus pyriformil, Chandler) infections among 14 species of fish collected from the Maple River in Buena Vista and Ida Counties in western Iowa. Prevalence estimates ranged from 0% to 47.4% with a mean prevalence of 11.9%. The rank ordering of odds ratios of infection allowed the species to be categorized as those with risks greater than, less than, and not different from average risk to infection within the Maple River sample. The species with the largest odds ratio was the bluntnose minnow, (Pimephales notatus) (odds ratio …

Expression Of Heterosis In Leaming And Midland Corn Belt Dent Populations, M. J. Carena, A. R. Hallauer

Journal of the Iowa Academy of Science: JIAS

Successful maize (Zea mays 1.) breeding programs are based on specific heterotic patterns. The Iowa Stiff Stalk Synthetic x Lancaster Sure Crop heterotic pattern is widely exploited in U.S. maize breeding programs. Alternative U.S. heterotic patterns have been suggested, but they have received limited attention and improvement. The objectives of this study were to evaluate cultivar crosses between Leaming and Midland Yellow Dent cultivars before and after inbred progeny selection and to assess their potential as an alternative U.S. heterotic pattern. Grain yield had a midparent heterosis value of 4.9% before selection and 17.8% in the third cycle of selection. …

Myxomycetes Of Big Bend National Park, Texas, Lois H. Tiffany, George Knaphus

Journal of the Iowa Academy of Science: JIAS

Seventy species of Myxomycetes have been collected directly in the field or observed later in the laboratory from field materials in moist chambers from Big Bend National Park, Texas. Collections were made over a 10 year period, 1989-1997 and 1999, during intensive seven-day fungus collecting trips to Big Bend in late September each year. McGraw (1968) in an earlier study of Texas Myxomycetes had reported 28 species from Big Bend, some of which were also found in this study. A total of 81 species are reported from the park. A variety of environmental conditions occurred during the 10 years with …

Lessons From An Inventory Of The Ames, Iowa, Flora (1859-2000), William R. Norris, Deborah Q. Lewis, Mark P. Widrlechner, Jimmie D. Thompson, Richard O. Pope

Journal of the Iowa Academy of Science: JIAS

A botanical survey of the vascular flora of the "planning and zoning jurisdiction" of the city of Ames, Iowa (i.e., the area within a boundary 3.2 km beyond the current city limits) was compiled from 1990 to 2000. During this survey, 916 taxa (71 % native) were encountered within chis boundary. Literature reviews and a survey of Iowa State University's Ada Hayden Herbarium for specimens that had been collected in Ames since 1859 add 204 taxa to the flora. This total of 1,120 taxa exceeds the number of taxa known from any comparable area (including counties) in Iowa. We produced …
