Verbal Discrimination Learning As A Function Of Anxiety And Task Difficulty, James T. Freeman, Richard I. Moren

Proceedings of the Iowa Academy of Science

Several studies have reported data bearing on the relationship between anxiety and various measures of discriminative behavior. Work by Spence and his associates (3, 4) seems uniformly to suggest that higher anxiety levels are associated with superior performance in differential eye-lid conditioning while the work of Hilgard et al (2) demonstrates impaired performance of high-anxiety Ss in the differential eyelid-conditioning situation. It must be noted that these studies involved relatively simple tasks. There is, however, some suggestion from perceptual studies involving somewhat more complex response measures (and where notably competing response tendencies were more prevalent) that discriminative performance is also …

A Test Of Learning With Responses Minimized By The Use Of A Movable Maze, Charles F. Haner, Richard Peterson

Proceedings of the Iowa Academy of Science

Several experiments have investigated the possibility of learning when their subjects have been either restricted in their movements or proprioceptive cues have been reduced. A number, as Harlow and Stagner (1), have restricted movement by the use of drugs (as curare). Thorndike (2) suggests a series of "experiments which aim to provide opportunities to acquire expectations with a minimum of helpful association of accompanying impulses." Typical of these suggested studies was the following: A rat might be placed in a cage which was mounted on wheels. The cage would then be pushed through a simple maze and the animal rewarded …

Discussion Of "Psychological Research And Mental Health", Leonard Worell

Proceedings of the Iowa Academy of Science

Although the papers in the symposium deal with quite diverse topics, there are at least two points of similarity. First, it is apparent that all the participants felt somewhat uncomfortable about and restricted by the concept of mental health. This is, of course, understandably related to the absence of a clear definition of the term. Now, it seems to me that there are at least three ways in which the concept may be employed, two of which have been used by varying participants.

Growth Of Oaks In Southeastern Iowa In Relation To Stand Density And Grazing, A. L. Mccomb, G. W. Thomson

Proceedings of the Iowa Academy of Science

High yields of wood depend upon maintaining forest stands of "optimum" density and providing levels of water, nutrients, light and heat sufficient for the full development of different species as determined by their genetic potentials. European studies of growth in relation to stand density have yielded somewhat contradictory results. Møller (1954) indicates that growth increases with increasing stand density up to about 50 or 60 percent of the maximum attainable density; beyond this there is either no change or a slight decrease in growth depending upon the criterion for growth used. Assmann (1955) and Mitscherlich (1954) have found maximum growth …

Fungi New To Iowa, J. C. Gilman, L. H. Tiffany, R. W. Lichtwardt

Proceedings of the Iowa Academy of Science

In Carrying on mycological investigations of diverse sorts, fungi that have an especial interest are frequently encountered. Such fungi may be noteworthy because of their rarity, the fact that they are on hosts not hitherto listed for them, or have apparently come from great distances. Twelve species are included, with descriptions and illustrations when the latter were available. Two Cokeromyces recurvatus and Syncephalis reftexa, are Phycoinycetes; seven, Diaporthe taleola, D. phaseolorum, Fenestella vestita, Byssocldamys nivea, Myxotrichum spinosum, Lophotrichus ampullus, Leptosphaeria gigaspora, are Ascoycetes; and three, Hyalothyridium calamagrostidis, Crocicreas atroviridis, and Septoria caraganae, belong to the Fungi Imperfecti.

Observations On The Effect Of Logging On The Spread Of Oak Wilt In The Brayton Memorial Forest, Iowa, Kathleen C. Fritch, Mary K. Schwarte, Harold S. Mcnabb Jr.

Proceedings of the Iowa Academy of Science

The oak wilt disease, caused by Endoconidiophora fagacerum Bretz, has been present in the Brayton Memorial Forest, near Hopkinton, Delaware County, Iowa, for many years. The actual date of original infection is unknown. Prior to 1951, the forest was left unmanaged and no disease control was attempted. During that year, a 100 percent inventory was made of the trees killed by this disease on a 38.6-acre tract within the forest (Brinkman 1952).

Distribution Of Spartina Pectinata Link In Iowa, David G. Mobberley

Proceedings of the Iowa Academy of Science

Earlier taxonomic studies in the genus Spartina of the Gramineae show the existence of but one of the sixteen species in Iowa, Spartina pectinata Link. That it is widely distributed throughout the state is evident from Figure 1. The counties identified by dots have yielded specimens presently accessioned into the herbaria of Iowa State College, State University of Iowa and Simpson College. In addition, the species has been observed in numerous other counties although records are not authenticated by specimens entered into institutional herbaria.

A Contribution To The Embryology Of Dilleniaceae, A. Nagaraja Rao

Proceedings of the Iowa Academy of Science

Dilleniaceae is chiefly an australasian and tropical american family with herbs, shrubs and trees. The two arborascent genera like Dillenia and Wormia are present in South India and Ceylon respectively. The former is very common in the western ghats of Mysore State, India, well represented by D. pentagyna and D. indica. Many species of Wormia are present in Ceylon. Gilg and Werdermann (1925) include both the genera under the fourth sub-order of the family Dillenieae, in 'Die naturlichen Pflanzenfamilien'. The earlier literature on the embryology of this family shows that three genera have been investigated so far; Schnarf (1924) on …

Notes On Stem Rusts Of Hard Pines In Iowa, Harold S. Mcnabb Jr., Malcolm C. Shurtleff Jr.

Proceedings of the Iowa Academy of Science

Tree disease specimens sent to Iowa State College for identification, during the past two years, have yielded what is believed to be two new rust records for Iowa. Because of this, and the fact that under certain conditions these diseases could become important, a few comments on these collections are presented.

Electrophoretic Analysis Of The Serum Proteins Of Normal Newborn Infants, Margaret Real, J. I. Routh

Proceedings of the Iowa Academy of Science

The protein components of the serum of newborn infants have occupied the attention of few investigators. McKhann and Kapnick (1) pointed out that newborn infants show an immunity to many diseases during the first months of life. Electrophoretic studies carried out by Tiselius and Kabat (2) demonstrated that the gamma globulin fraction of the serum contains the antibodies. Other investigators (3, 4, 5) reported a low ratio of albumin to globulin in the serum of newborn infants. The increase in globulin was shown to be mainly in the gamma globulin component (6, 7, 8, 9). Since the technique of filter …

Electronics In Medical Research, Victor W. Bolie

Proceedings of the Iowa Academy of Science

Due to modern achievements in science, and increasing public support, medical research in the United States is gaining a strong foothold, particularly in the areas of cancer and heart disease. Medical research work demands the best available efforts from many different fields of science. Chemistry has and will continue to play a dominant role. Only in recent years, however, has the science of electronics emerged to· a place of major significance. The measurement of biological functions by means of extremely sensitive electronic methods presents a vast new horizon otherwise unattainable in the search for medical knowledge.

Lignins As Stabilizing Agents For Northeastern Iowa Loess, S. P. Sinha, D.T. Davidson, J.M. Hoover

Proceedings of the Iowa Academy of Science

One of the common problems in highway .and airport construction faced by engineers all over the world is the scarcity of suitable materials for base and subbase construction. Lately, there has been such an increase in traffic on highways and airfields that the problem of suitable base and subbase design can no longer be ignored. Engineers have been striving hard to find ways and means to solve this problem. One solution lies in the utilization of locally available materials. Since soil is the most plentiful of available materials, it has been chosen by engineers and scientists to do the job. …

Cavitation As A Means Of Cleaning Silt Grains, Donald L. Biggs

Proceedings of the Iowa Academy of Science

Microscopic examination of silt grains from soils shows them to be coated with a brown, clay-like film that makes mineral identification difficult or impossible. Minerals like zircon, tourmaline, rutile and other heavy minerals are less affected by the coating than are feldspar and quartz. This latter pair make up the largest fraction of the silt and the inability to distinguish between them rapidly and easily is important. Washing with distilled water and dispersion with sodium metaphosphate failed to remove the brown coating from the silt grains. It was decided to attempt removal of the coating by ultrasonic cleaning. The instrument …

Soil Stabilization With Large Organic Cations And Polyacids, R. L. Nicholls, D. T. Davidson

Proceedings of the Iowa Academy of Science

Previous studies at the Iowa Engineering Experiment Station have demonstrated the superior water-proofing ability of large organic cations as soil stabilizing agents (1, 2, 3). A method of combining this water-proofing ability of a large organic cation with the cementing capacity of a polyacid is presently being studied. This report describes the mechanisms of water-proofing and cementing and presents results of the first part of the experimental work.

Further Correlation Of Consistency Limits Of Iowa Loess With Clay Content, J. B. Sheeler, D. T. Davidson

Proceedings of the Iowa Academy of Science

Mixing and manipulation of soil and water cause consistency changes at various moisture contents. These changes reveal important characteristics of the soil even though the condition of the soil-water system is not the same as that found in nature. The characteristics of consistency have been correlated with engineering behavior of soil. Together with mechanical analysis, these relationships provide a basis for the identification and engineering classification of a soil and aid in judging its suitability for engineering structures.

A Relocation Of Part Of The Mankato Drift Boundary In Hand County, South Dakota, Everett M. White

Proceedings of the Iowa Academy of Science

Flint (1) has shown the areal distribution of the Cary and Mankato glacial drifts in South Dakota. Studies of the distribution of soils in southern Hand County (2) make possible the refinement of the Mankato drift boundary in that area. Although the area in question is relatively small (approximately 95 square miles) when compared to the distribution of the two drifts in the state, it is a significant part of the county. The criteria used in relocating the boundary are: (1) kinds of soil profiles, (2) presence or absence of loess, (3) melt water channels and outwash, (4) composition of …

A Correlation And Structural Interpretation Of The Missourian And Virgilian Rocks Exposed Along The Middle River Traverse Of Iowa, T. L. Welp, L. A. Thomas, H. R. Dixon

Proceedings of the Iowa Academy of Science

During the summer of 1956 the authors undertook an extensive study of the Pennsylvanian rocks exposed in Iowa and the adjacent states of Nebraska and .Missouri, in an effort to locate rock formations that would be suitable for the production of aggregate for use in highway construction work. The rocks exposed along the Middle River, that extends from the vicinity of Winterset, Madison County, to just southwest of Casey, Adair County, a distance of about 35 miles is one of the first areas that has been thoroughly investigated.

The Devonian Section At The Klein Quarry, Johnson County, Iowa, R. D. Michael, T. L. Welp

Proceedings of the Iowa Academy of Science

This paper is a renewal of a practice carried on by L. W. Wood in the 1930s, that of presenting each year one of the more interesting geologic sections encountered during the year's work by the members of the geology section of the Iowa State Highway Commission. The Devonian section at the Klein quarry in the NW¼, Sec. 2, T. 79 N., R. 7 W., Johnson County, was chosen because the exposed face and extensive coring offered an opportunity to study the members of the Cedar Valley formation and the upper members of the Wapsipinicon formation in a single location, …

Measurements Of Specific Heats By A Pulse Method, R. C. Strittmater, G. J. Pearson, G. C. Danielson

Proceedings of the Iowa Academy of Science

Calorimetric methods of measuring specific heats at high temperatures are slow and often involve laborious precautions to eliminate heat losses. Pulse heating methods are rapid and heat losses can be made negligible. The accuracy of the calorimetric methods, however, has been greater than that of the pulse heating methods, which need further development. The purpose of the present investigation was to develop further and to evaluate again one of the more promising pulse heating methods. Kurrelmeyer, Mais and Green (1) suggested in 1941 the use of pulse heating. Baxter (2) described in 1944 a pulse method in which the current …

Fuels For Calibration Of Fuel Flowmeters, J. P. Short

Proceedings of the Iowa Academy of Science

Approximately two years ago, a contract was signed between Bendix Aviation Corporation and St. Ambrose College of Davenport, Iowa, initiating the Student Industrial Research Program. For the past nine months, in conjunction with this program, work has been done on the project entitled "Fuels for Calibration of Fuel Flowmeters." It is a known fact that in calibrating any measuring device, it is necessary to use a standard reflecting the properties of the material to be measured in service. Specifically, we are concerned with aviation fuel flowmeters. It has recently become apparent that some jet fuels in current production depart from …

Science Vocabulary And Teaching, R. R. Haun

Proceedings of the Iowa Academy of Science

If it should be necessary to relate the work here reported to a theoretical background or to some current problems, such relationships could easily be found in the developing concepts about the psychology and philosophy of the thinking process and in the current discussions concerning critical thinking and the philosophy of science.
