The Iowa Academy Of Science: 1875-1975, Robert W. Hanson

Proceedings of the Iowa Academy of Science

In tracing the beginnings of the Iowa Academy of Science, Jacob Swisher acknowledged in 1930 that the meeting of the American Association for the Advancement of Science in Dubuque in 1872 probably had much to do with the formation of the first Iowa Academy in 1875. The Dubuque meeting was the first meeting of the AAAS west of the Mississippi River, and it was at that meeting that many of the charter members of the first Academy began to develop a closer association with one another. An excursion across Iowa following the AAAS meeting touched various points of scientific interest …

The Iowa Academy Of Science Parish Farm: A Dream About Tomorrow, Harry T. Horner Jr.

Proceedings of the Iowa Academy of Science

A gift may be given for many reasons and what the receiver does with it may depend on many things. The Iowa Academy of Science Parish Farm fits this situation and serves as an appropriate focal point to tell a story-a story with a beginning and a developing plot, but one whose ending is yet to be written, if ever. The Farm story represents a relatively small part of the Academy's first hundred years, yet its potential is great for becoming a significant and unique part of the second hundred years. Just like those who may excitedly look back in …

The Development Of Archeology In Iowa: An Overview, Duane C. Anderson

Proceedings of the Iowa Academy of Science

This paper traces the development of archeology in Iowa through three distinct periods. Workers during the period of Pioneer Investigations, 1870-1920, were preoccupied with the problem of the identity of the "Mound Builders." Through their activities they stimulated public awareness and interest and fostered the growth of scientific investigations. During the Keyes-Orr Period, 1921- 1950, Charles R. Keyes and his associates, working through the Iowa Archeological Survey, amassed a sizable amount of data and named various archeological cultures across the state. By the close of the Keyes-Orr Period, archeology emerged as a respected, disciplined and important pursuit in Iowa. The …

Mycology And Plant Pathology In Iowa From 1854 To 1974, George Knaphus

Proceedings of the Iowa Academy of Science

A historical survey such as this cannot be satisfying to the author. It demands too much compression of the incompressible and dictates deletion of many interesting incidents. A mountain of file cards and notes may translate into a tedious listing of authors, titles and sources. It may, on the other hand, capture the spirit of the times and the people. This summary of mycology and plant pathology in Iowa from 1854 to the present tries to do the latter. It is documented sparsely and informally, with most of the information coming from the Proceedings of the Iowa Academy of Science, …

Development Of Air Passages, And Crystal Distribution, In The Stem Of Bacopa Caroliniana (Scrophulariaceae), Nels R. Lersten, James L. Gunning

Proceedings of the Iowa Academy of Science

About 20 vertical air passages occur in each internode, separated at each node by a solid diaphragm of parenchyma, in which leaf traces depart. Air passages are schizogenous and begin to form just below the shoot apex. This may be the first report of druse crystals in Scrophulariaceae. Druses become visible in the second nodal plate below the shoot apex. In the mature stem, druses are more common in nodes, but they also occur in internodes. The stele appears to be an ectophloic siphonostele, without separate vascular bundles at any stage of development. This appears to be a good species …

Fern Reproduction At Woodman Hollow, Central Iowa: Preliminary Observations And A Consideration Of The Feasibility Of Studying Fern Reproductive Biology In Nature, Donald R. Farrar, Robert D. Gooch

Proceedings of the Iowa Academy of Science

Field observations of spore availability, gametophyte establishment and survival, and sporophyte production were made over a one-year period. Maximum spore release for most species occurred shortly after spore maturation in mid to late summer, but some spores remained on sporophyte fronds through the winter and were available for germination the following spring. Gametophytes of Cystopteris fragilis, Woodsia obtusa and Adiantum pedatum became established in late summer and fall. Production of sporophytes occurred both in fall and in the following spring. Both gametophytes and juvenile sporophytes survived the winter in relatively unchanged condition. Results indicate that it is feasible and important …

The Oldest Iowa Tree, Ii: Eastern Red Cedar On Cedar River Bluffs, Roger Q. Landers, Dolores Graf

Proceedings of the Iowa Academy of Science

When Anderson (1938) described the oldest tree in Iowa, he was using wood from an eastern red cedar, Juniperus virginiana L., which had originated ca. 1516 and died ca. 1885, presumably near the Schramm family cottage on West Lake Okoboji. Our sample, also from eastern red cedar, is a core from a tree growing on a steep limestone bluff overlooking the Cedar River in Palisades-Kepler State Park. The 16 cm (6 1/4 in.) core, taken in April, 1965, by Graf and R. Wm. Poulter, was set aside then because the slender tree showed little outward sign of old age compared …

Introduction To A New Series Of Studies Of Ordovician Echinoderms, H. L. Strimple

Proceedings of the Iowa Academy of Science

A massive collection of Ordovician echinoderms has been accumulated primarily from northeastern Iowa and southeastern Minnesota but including material from other states; it is in process of being studied. A brief history of the inception of the study and the process of bringing the material together is presented. Individuals are named but only brief details are given. Primarily this is a report of a concentrated effort to produce a significant study of echinoderms from Middle and Upper Ordovician strata, the people involved and the methods of obtaining material.

Erisocrinids (Crinoidea-Inadunata) From Middle Pennsylvanian Rocks Of Iowa And Colorado, H. L. Strimple

Proceedings of the Iowa Academy of Science

Erisocrinus knoxvillensis n. sp. is described from rocks of the Desmoinesian Stage exposed near Knoxville, Marion County, Iowa. Two specimens from the Madera Formation, Desmoinesian Stage, Heurfano Park, Colorado, reported by Tischler, 1963, as belonging to the genus Erisocrinus are described as Exaetocrinus maderaensis n. sp. and Pontotocrinus coloradoensis n. sp. The lectoholotype of Erisocrinus typus Meek & Worthen, type species of the genus, is illustrated.

Recurrent Community Patterns In Epeiric Seas: The Lower Silurian Of Eastern Iowa, Markes E. Johnson

Proceedings of the Iowa Academy of Science

In eastern Iowa, the Llandovery Series (Lower Silurian) consists of the Edgewood and Kankakee formations as well as much of the Hopkinton Dolomite. Outcrops of these rocks provide fossil assemblages of marine benthic invertebrates well suited for reconstructing epeiric sea communities. Results of preliminary field studies in Dubuque, Jackson. Jones, and Delaware counties indicate that an initial Lingula Community at the base of the section is succeeded by recurrent patterns of Coral, Pentamerid, and Stricklandid communities. The patterns are interpreted as community response to fluctuations in sea level, estimated to vary between a few and 60 m. At least two …

Technology Transfer: The Adoption Of Gobar Gas Generators By Subsistence Farmers In Puebla, Mexico, Robert E. Meyer

Dissertations and Theses @ UNI

One of the significant characteristics of modern American agriculture is its rapidly changing technology. New practices and techniques are constantly being developed by research agencies. Society benefits from these research findings only to the extent that they are diffused to and used by farmers.

One of the important problems inherent in a rapidly changing economy is that of effectively communicating scientific information to the potential user of that information. Much research has been done in recent years to determine the nature of the process by which new ideas and practices are diffused from their source of origin and ultimately implemented. …

Gas Phase Hydrogen Bonding Infrared Studies Of Four Simple Alcohols, Lawrence John Anderson

Dissertations and Theses @ UNI

The purpose of this study was to develop methods for studying gas phase hydrogen bonding and to obtain evidence of the gas phase self association of methanol, ethanol, 2-propanol and 1-propanol. A gas sample transfer manifold was designed and constructed. The gas -1 8 -1 phase infrared spectra from 3050 cm to 3800 cm of methanol, ethanol, 2-propanol and 1-propanol were examined at low and saturated pressures at approximately 4o0 c. The measured integrated absorption areas of the methanol spectra were compared to areas calculated from results found in the literature. The areas were found to be in reasonable agreement …

A Study Of The Loss-Of-Innocence Theme In Selected Novels Of Robert Penn Warren, Beverly S. Fisher

Dissertations and Theses @ UNI

Using Mordecai Marcus's ''What Is an Initiation Story?" and R. W. B. Lewis's The American Adam to define the loss of innocence, this study follows the protagonists of three Robert Penn Warren novels-- Wilderness, World Enough and Time, and All the King's Men--through their steps from innocence to knowledge, initiation, or the loss of innocence. A similar pattern is seen in the lives of Adam Rosenzweig, Jeremiah Beaumont, and Jack Burden. Each is well beyond the age normally associated with initiation and has gone through experiences which should have caused the loss of innocence. Each has refused the initiation (at …

A Diagnostic-Prescriptive Procedure For Teaching Adolescent Dyscalculics, Constance Ellingson Byrnes

Dissertations and Theses @ UNI

A procedure of individual diagnosis and educational prescription was developed for classroom teachers in the regular school program. A means of gathering and managing data including the use of task analysis was recommended. The procedure was demonstrated in selected case studies. A five-part model was developed to systematically diagnose the learning problem manage the information gathered in the diagnosis, and present a prescription or teaching strategy to remediate the errors. Step I was the diagnosis of mathematical errors. Samples of mathematical computation were collected. Errors were selected for prescription if the student made systematic errors and if a series of …

Germination Of Prairie Forbs Liatris Aspera Michx. And Amorpha Canescens Pursh, Lewis Marshall Churbuck

Dissertations and Theses @ UNI

Seed of Liatris aspera and Amorpha canescens were hand collected from the Mark Sand Prairie in Eastern Iowa during the fall of 1973 and 1974. There was no significant difference in the viability between one and two year old seed with both species. There was no significant difference in the total germination at 21 C for L. aspera and A. canescens. A. canescens required a significantly longer period of time for the two year old seed to germinate. The most rapid, regular and complete germination of L. aspera occurred at 21 and 27 c. significantly reduced at 16 and 32 …

Na Tse Ke: A Re-Evaluation Of Some Major Trends In United States Apache Policy, 1847-1887, D. C. Cole

Dissertations and Theses @ UNI

The relationship of the United States Government and the Apache Indians of Arizona and New Mexico was marred by thirty years of war. The thesis, of which this is an abstract, is an investigation into the appropriateness of selected aspects of United States policy toward the Apache in the years 1847-1887. The essential questions in this analysis and re-evaluation of policy are not why and how? did the United States prevail, but rather: Did the authorities understand the nature of the Apache? Did the policies in the area fit that nature? And if not, could the cost have been less …

The Readability Level Of The Newberry Award Books And The National Book Awards For Children, 1969-1975, Marilyn R. Wood

Graduate Research Papers

So many conflicting opinions have been advanced about the popularity of the Newbery books with children, the grade level they are best suited for, and the value of encouraging children to read these books. The National Book Awards for Children have caused less controversy, perhaps because they have not been around as long. Yet, the same criticisms and comments could be made about these books also.
