Dara were collected using Mo K_ἀ radiation and refinement converged to R = 0.027 based on the 1996 unique reflections with |F_o|≥3δ(F_o). The iodine atoms were found coexist in two …

Testing The Accuracy And Precision Of Wetness Sensors In A Tomato Field And On Turfgrass, Kara J. Potratz, Mark L. Gleason, Melanie L. Hockmuth, Sharon K. Parker, Glenn A. Pearston

Journal of the Iowa Academy of Science: JIAS

Measurements of dew-period duration by painted, flat-plate, electronic wetness sensors at the top of the plant canopy in a tomato field and on adjacent turfgrass were compared with visual observations. The response range of sensors during the onset of dew sometimes exceeded 5 hr. but was less than 1 hr. on other nights. Sensors in the tomato field indicated dew formation occurred as much as 2 hr. earlier or later than dew became visible on adjacent tomato leaflets at the top of the crop canopy. A calibration threshold for sensors derived from a drying curve resulted in the underestimation of …

Evaluation Of Implanted Radio Transmitters In Pheasant Chicks, Dean E. Ewing, William R. Clark, Paul A. Vohls

Journal of the Iowa Academy of Science: JIAS

We studied game-farm pheasant (Phasianus colchicus Linneaus) chicks implanted with miniature transmitters to determine if surgery and implantation affected growth, behavior, or survival. Transmitters (weighing 1.2 g) were implanted subcutaneously in the interscapular region in day-old chicks. In Experiment 1, biological effects on chicks with transmitters implanted were compared with data from a control group. In Experiment 2, the effects of anesthesia only, anesthesia with an implanted transmitter, and implanted transmitter only were compared with a control. We measured responses of weight gain, survival, and pecking behavior in each experiment. In Experiment 1, we found no significant differences in weight …

Soybean Residual Effects On A Subsequent Maize Crop, E. S. Escuro, D. N. Sundberg, R. M. Shibles

Journal of the Iowa Academy of Science: JIAS

Maize (Zea mays 1.) grown after soybean (Glycine max 1. Merr.) consistently performs better than maize that follows itself (second year maize), irrespective of nitrogen fertilization. In previous studies of the soybean-maize rotation, there never has been an evaluation of the potentially different effects of soybean genotypes on following maize. A two-year, soybean maize rotation was initiated in Ames at 1988 with the first year planted to various soybean genotypes, a maize hybrid, and oat (Avena sativa 1.). These were followed in the second year by a single maize hybrid with 0, 80, 160, and 240 kg/ha N fertilization levels. …

A Cross-Cultural Anthology Of Mythological Flood Stories, Gayle R. Kelley

Graduate Research Papers

This project is a literary production of mythological flood stories to help children better understand cultural diversity. Candidate stories for this project were reviewed through the application of several sets of filtering criteria developed by the author and based on tests described in the literature, to determine which stories would be used. The accompanying document includes nine stories from six continents, as rewritten by the project author. With each mythological flood story is a short narrative describing the background of the story, its cultural roots, or anything else that would bring life and interest to the retelling. This anthology will …

Nonverbal Communication In The Work Place As Perceived By Men And Women, Judith Lou Loonan

Graduate Research Papers

In order to understand the issue of nonverbal communication in the workplace as perceived by men and women, the work history of men and women and how they arrived at the present point of communication must be looked at. It must also be established what the meaning of nonverbal communication is. This research will provide a guide to establish these two points. After World War II, and especially within the past 20 years, more and more women have entered the work force. "It is estimated that by the year 2000, the percentage of women will grow to 50% of the …

The Portrayal Of Iowa In Fiction Books For Children And Youth, Jeanette Gerrietts

Graduate Research Papers

This research study examined the content of books read by children and youth in grades three through twelve to determine how Iowa is portrayed in books published in the period from 1980 to the present. Questions studied were:

1. What characteristics of Iowa are found most frequently in fiction books for children and youth?

2. How accurate are these portrayals in reflecting the actual 3 characteristics of the state as reported in the 1980 and 1990 census?

Culture And Cognition: The African American Thinker In The Classroom, Steve K. Hunt

Dissertations and Theses @ UNI

In recent years, the importance of recognizing the unique characteristics of different cultures has drawn increased attention. In fact, many scholars have suggested that educators must be especially concerned with understanding the implications of cultural diversity in the classroom. Specifically, educators are becoming increasingly aware that different cultural groups may utilize different cognitive styles in the classroom. The purpose, of this study was to identify the cognitive styles utilized by African American students in the classroom. The participants in this study were students of a large urban high school in an Iowa community of approximately 95,000. The 43 students who …

Personal Space And Territoriality Of Users In An Academic And Public Library, Ruth A. Hamilton

Graduate Research Papers

An observation checklist was used to investigate responses of patrons to intrusion in their personal space. The study was done in a small academic library and a small public library. After the subject was seated an intruder would come in and sit as close to the subject as possible. The responding time was limited to five minutes. The response of the subject was recorded on a detailed checklist. Findings indicated that female subjects make more adjustments than male subjects. In general, adjustments made by subjects were minimal in number and minor in nature.

Ecoregions And Subregions Of Iowa: A Framework For Water Quality Assessment And Management, Glenn E. Griffith, James M. Omernik, Thomas F. Wilton, Suzanne M. Pierson

Journal of the Iowa Academy of Science: JIAS

Ecoregion frameworks are valuable tools for inventorying and assessing environmental resources, for setting resource management goals, and for developing biological criteria and water quality standards. In a collaborative project between the Iowa Department of Natural Resources (DNR) and the U.S. Environmental Protection Agency (EPA), we have refined boundaries of the EPA's five ecological regions of Iowa and defined six subregions of the Western Corn Belt Plains ecoregion within the state. Lists of candidate stream reference sites have been developed to date for the seven largest regions, and the sites were visited and evaluated by Iowa DNR and U.S. EPA personnel …

Post-Natal Survival Of Raccoons In Relation To Female Age And Denning Behavior, Jonathan J. Judson, William R. Clark, Ronald D. Andrews

Journal of the Iowa Academy of Science: JIAS

We measured post-natal survival of radio-collared raccoons 1-5 months old in southwest Iowa, 1988-1989. We compared survival of young nurtured by yearling and adult females and related den site selection to survival functions using proportional hazards models. Adult females used upland and farmstead habitats note frequently than yearlings, whereas yearling females used lowland habitats note frequently. Tree cavities and beds on the ground were used most frequently. Adult females denned in buildings 13% of the time and in holes in the ground 9.5% of the time, whereas yearlings frequently tested with litters in beds on the ground (31%). Microhab1tat characteristics …

Influence Of Reduced Leaching On Growth Of Seedlings Of Black Locust Inoculated With Rhizobia, William R. Graves, Sandra R. Anfinson

Journal of the Iowa Academy of Science: JIAS

Seedlings of black locust (Robinia pseudoacacia L.) were inoculated with compatible rhizobia and irrigated twice each week with solution containing either 50 or 150 mg nitrogen/L. Leaching fraction treatments of 0, 0.2, or 0.4 were maintained for 6 weeks. Seedlings supplied 50 mg nitrogen/L grew poorly compared co planes supplied 150 mg nitrogen/L regardless of leaching fraction. Dry masses of shoots and of entire planes were lower for seedlings in the 0 and 0.2 leaching fraction treatments compared with chose in the 0.4 treatment. Neither leaching fraction nor applied nitrogen concentration appeared co affect the number of nodules per plant, …

Water Quality Monitoring (1988 To 1991) At The Iowa Academy Of Science's Parish Farm, Grundy County, Iowa, Brenda K. Nations, George R. Hallberg

Journal of the Iowa Academy of Science: JIAS

In May 1988 sampling was initiated to evaluate water quality in relation to management practices at Parish Farm, which is owned by Iowa Academy of Science. Initial results showed tile-line effluent to have high concentrations of nitrate-nitrogen (N0₃-N). Twelve monitoring wells were installed over a one year period to analyze shallow groundwater at the farm. The wells, tile lines, and surface water were sampled monthly, through October, 1991, and the water analyzed for N0₃-N and some pesticides. N0₃-N concentrations varied, related to landuse and management of adjacent areas. Greater N0₃-N concentrations were …
