Comparing Three Bee Species For Controlled Pollination Of Selected Brassicaceae, R. L. Wilson, C. A. Abel, R. L. Luhman

Journal of the Iowa Academy of Science: JIAS

Pollination of species of Brassicaceae for seed increase at the USDA-ARS North Central Regional Plant Introduction Station (NCRPIS) has been accomplished for several years by using nucleus hives of honey bees, Apis mellifera L., in field cages. Brassicaceae are cool season crops that need pollination from late April to early June in the north temperate zone. Overwintered hives of honey bees need time to strengthen (i.e., increase their numbers) and thus it is difficult to make enough nuclei to meet our early season pollinations needs. Purchasmg package bees from suppliers in the southern U.S. is an expensive alternative. In this …

Distribution And Persistence Of Phyllachora Species On Poaceae In Iowa, A. C. Gabel, L. H. Tiffany

Journal of the Iowa Academy of Science: JIAS

Phytlachora spp. on Poaceae were collected to determine species present, grass hosts and distribution in Iowa. From 1959-1996 the fungus was collected 240 times from 67 different sites in 35 counties. Seven species of Phytlachora were collected on 25 species from 13 genera of grasses. P. graminis was collected 89 times from 43 sites on four species of Agropyron, two species of Calamagrostis, three species of Elymus, Hystrix patula, Panicum virgatum, and Setaria glauca. Seventy-two specimens of P. luteo-maculata on Andropogon gerardii or Schiziichyrium scoparium were collected from 30 sites. The study included 20 collections of P. cynodontis on Bouteloua …

Characterization Of Central Iowa Forests With Permanent Plots, James W. Raich, Donald R. Farrar, Ruth A. Herzberg, Eenam Sin, Cindy L. Johnson-Groh

Journal of the Iowa Academy of Science: JIAS

We describe a standard methodology for establishing and inventorying the woody vegetation in 0.1-ha permanent forest plots and we utilize the data from 86 plots to characterize the mature forest vegetation of central Iowa. Obvious differences existed between bottomland hardwoods and upland forest stands, but disturbed uplands contained species typical of bottomlands. Little-disturbed upland forest plots included a variety of species associations, but variation among plots was continuous. The trees dominating the mature upland forests of central Iowa grow in a wide variety of habitats, with the result that predictability of stand structure at any location is limited. Stands on …

Can Mathematics Be Taught In A Christian Way?, Johan Deklerk

ACMS Journal 2004

Some people would argue that mathematics cannot be taught in a Christian way. Others would say it can be done, but that they are unsure how to do it, and therefore do not do it. Some methods mentioned from time to time will be briefly discussed in this address. The question will be asked whether these techniques bring one closer to a Christian perspective on mathematics. My view is that some of these methods are just not sufficient and that more should be done. More attention should be paid to the context in which a mathematical subject is imbedded. Attention …

Lewis Carroll: Author, Mathematician, And Christian, David L. Neuhouser

ACMS Journal 2004

Although a Christian, an author, and a mathematician, Charles Letwidge Dodgson (better known as Lewis Carroll) wrote very few works in which these three aspects of his person was present. The only examples of him merging these interests are in Sylvie and Bruno and Sylvie and Bruno Concluded. This paper will explore what motivated him to make these works and whether or not they were successful.

The Deconstruction Of Mathematics, David J. Stucki

ACMS Journal 2004

Mathematics, as an academic discipline, has stood for many years as the last bastion against a growing tide of intellectual relativism that has become all but ubiquitous. More recently, however, efforts have been made to "humanize" mathematics by advocating a social-constructivist approach to the philosophy of mathematics, both in practice and education. This paper is intended to serve as a critical response to one advocate of this approach, Reuben Hersh (What Is Mathematics, Really?, 1997), and in the process a defense of Platonism.

Chlorophyll Meter Assessments Of Corn Response To Nitrogen Management Practices, M. M. Siambi, D. L. Karlen, R. M. Shibles

Journal of the Iowa Academy of Science: JIAS

Environmentally sound nitrogen (N) management is necessary to simultaneously achieve high crop yields and protect surface and groundwater quality. We evaluated a hand-held chlorophyll meter as a diagnostic tool for improving management for corn (Zea mays L.). Five N fertilizer rates (0, 67, 134, 201 and 280 kg N ha^-1) were evaluated in one study, and in a second study, the meter was used to evaluate the N status of corn plants grown under varying tillage (chisel plow vs no-till), crop rotation (continuous corn vs corn-soybean [Glycine max (L.) Merr.]), and N management treatments. Meter readings were …

Community College Perspectives On Teacher Preparation In Virginia, D. L. Neely-Fisher

Journal of Mathematics and Science: Collaborative Explorations

The need for future teachers who are well versed in mathematics and science will not be provided by Virginia’s four-year institutions alone. A large portion of those students who complete their K-8 teacher preparation programs at Virginia’s four-year institutions have studied a significant portion, if not all, of their mathematics and science at community colleges. Therefore, if future teachers are to have completed appropriate mathematics and science courses these must be provided by the community colleges. In addition, community colleges can play a critical role in attracting people with a high potential for becoming excellent teachers. Two-year colleges are located …

Experimental Design At The Intersection Of Mathematics, Science, And Technology In Grades K-6, R N. Giese, M. M. Mason

Journal of Mathematics and Science: Collaborative Explorations

Interdisciplinary courses, highlighting as they do the area(s) the disciplines have in common, often give the misperception of a single body of knowledge and/or way of knowing. However, discipline based courses often leave the equally mistaken notion that the disciplines have nothing in common. The task of the methods courses described in this paper is to reach an appropriate balance so that our pre-service elementary (K-6) teachers have a realistic perception of the independence and interdependence of mathematics and science. At the College of William and Mary each cohort of pre-service elementary teachers enrolls in mathematics and science methods courses …

Curriculum Restructuring At Lynchburg College: Effects Of Realignment To State-Mandated Competencies And Implications For K-6 Math And Science Teacher Preparation, W. Mckenzie, C. Messerschmidt

Journal of Mathematics and Science: Collaborative Explorations

Because Lynchburg College offers a four-year program to attain teacher licensure, current restructuring efforts have been aimed at targeting the professional studies requirements across a program of courses that are efficiently integrated. Math and science methods courses will be combined into a workshop course. A new general studies program has been approved which requires eight hours of lab sciences and three hours of math. A General Science course has been approved which will be geared towards pre-service teachers. The professional core requires an additional eight hours of lab sciences, totaling 16 hours in science, and six hours of math, geared …

Wonders Of Technology-Teaching Physics To Non-Scientists, V. A. Niculescu, P. Martin

Journal of Mathematics and Science: Collaborative Explorations

Wonders of Technology is a conceptual physics course developed for non—science majors. The approach taken here in the introduction of the physical concepts is to depict their role in today’s technology, specifically the technology familiar to the students, and also to emphasize the connection between technology, art, and culture from the historical perspective. Why this approach? The traditional method of teaching physics is perceived by many students as "user-unfriendly" — they think physics is difficult, abstract, and, in fact, of little or no relevance to everyday life. The course Wonders of Technology alleviates this perception by placing the students on …

Book Review: Places Of Quiet Beauty: Parks, Preserves, And Environmentalism, Cornelia F. Mutel

Journal of the Iowa Academy of Science: JIAS

Places of Quiet Beauty: Parks, Preserves, and Environmentalism. Rebecca Conard. 1997. University of Iowa Press, Iowa City, Iowa. XV + 382 pages. ISBN 0-87745-558-9.

Well administered, parks become much more than havens for birds and flowers, much more than game-preserves, a refuge for life of every sort; even more than a play-ground for all the people ... [The well administered park] shall show us real democracy.

So began one of Iowa's preeminent natural historians, Thomas Macbride, in an early-20th-century (1922) address on the status of Iowa's parks. And so Rebecca Conard begins her late-20th-century analysis of the development of Iowa's …

Planting Method And Fertilization Timing Effects On Ridge-Till Corn, Keith A. Kohler, Mohammadreza Ghaffarzadeh, Richard M. Cruse

Journal of the Iowa Academy of Science: JIAS

Fertilizer application technology has improved fertilizer use efficiency in ridge-till systems, but little work on planting methods and application timing within these systems has been done. A study was conducted to evaluate corn (Zea mays 1.) response to injected nitrogen (N) fertilizer applied to different planting methods at common application times. The performance of the late spring soil nitrate and the basal stalk nitrate tests was examined within these systems. A continuous corn and a corn-soybean [Glycine max (1) Merr.] rotation were used in 1989-1991 at two Iowa locations on Nicolett and Monona series soils, line-loamy, mixed, mesic Typic …

The Species Richness Of Birds Visiting A Yard Is Influenced By The Feeders/Seeds Present, David Joseph Horn

Journal of the Iowa Academy of Science: JIAS

Although seed preferences of species that visit bird feeders have been well documented, we know little about feeder/seed combinations most appropriate for attracting highest species richness or increasing abundance of individual species. I studied how the species composition of birds visiting a feeding station was influenced by addition of feeders filled with mixed seed, thistle, and suet in a yard that previously contained only a feeder with sunflower seeds. Addition of a seed mixture consisting of hulled sunflower, hulled peanuts, hulled millet, and hulled "tree" nuts in an elevated platform feeder increased species richness and total number of birds visiting …

The Vascular Flora Of Doolittle Prairie State Preserve - A Prairie Pothole Wetland Complex, Paul R. Wetzel, William R. Norris, Kevin M. Lyles

Journal of the Iowa Academy of Science: JIAS

Doolittle Prairie State Preserve is a 10 ha prairie pothole wetland complex located in Story County, central Iowa. A vascular flora of Doolittle Prairie is compiled and the prominent vegetation communities and zones described based on field observations by the authors and several additional investigators from 1982 to 1997. The preserve contains 14 shallow wetlands comprised of low prairie, wet meadow, and shallow emergent plant communities, as well as a disturbed prairie community and fence rows. These communities support a diverse vascular flora of 223 native species, plus 42 non-natives, representing 59 families and 178 genera. The Asteraceae (40), Poaceae …

Book Review: Iowa's Minerals: Their Occurrence, Origins, Industries, And Lore, Raymond R. Anderson

Journal of the Iowa Academy of Science: JIAS

Iowa's Minerals: Their Occurrence, Origins, Industries, and Lore. Paul Garvin. 1998. University of Iowa Press, Iowa City IA. vii + 260 pages. ISBN 0-87745-626-7 hdbd., ISBN 0-87745-627-5 (pbk.).

A mineral is defined as a "naturally occurring, chemically homogeneous crystalline solid." Every mineral has a composition, structure, and characteristics that make it uniquely different from every other mineral. In his new book, Paul Garvin, Professor of Geology at Cornell College in Mount Vernon, Iowa, presents a uniquely different discussion of Iowa's Minerals. While this book does contain the requisite discussions of mineral origins, chemistry, crystallography, and other descriptive information, Garvin enhances …
