The Academic Workplace: Perception Versus Reality, Sandra E. Elman

New England Journal of Public Policy

Why are faculty becoming increasingly dissatisfied with the quality of the academic workplace? What accounts for burnout and low morale among so many college and university faculty? Is work life for professionals any more satisfying in the business world? What can academic leaders learn from business executives who work vigorously to reenergize their enterprises? Are corporate strategies aimed at enhancing the quality of work life applicable to improving satisfaction and productivity in our colleges and universities?

These concerns were addressed by a number of education leaders at a conference on faculty work life jointly sponsored by the New England Resource …

Race And Excellence In American Higher Education, James Jennings

Trotter Review

W,E.B. DuBois’ assessment of American higher education’s posture toward black students in 1926 — “The attitude of the northern institution toward the Negro student is one which varies from tolerance to active hostility” — could have been written today based on several investigations. The American Council on Education reported recently that “the higher education community must continue to address the issues of losses in participation at all levels for blacks; the segregation of Hispanics; the retention and graduation of minority students, both undergraduate and graduate; the lack of growth for minorities in faculty and staff ranks.” The College Board reports …

Biological Pesticides: Biotechnology's Answer To Silent Spring, Donald H. Dean

Journal of the Iowa Academy of Science: JIAS

In the 25 years since the publication of Rachel Carson’s Silent Spring the public has come to realize the environmental impact of heavy use of chemical pesticides. To add insult to injury, many insects, including the disease vector, the mosquito, are now virtually resistant to standard chemical pesticides. Biotechnology is now providing a positive response to these dilemmas through the production and development of improved forms of microbial pest control agents: biological pesticides. Biological pesticides are pathogens, or predators, of insects such as bacteria, fungi, and viruses, and predatory insects or vertebrates such as mosquito fish which reduce the population …

Public Policy On The Introduction Of Genetically Engineered Microorganisms, Anne K. Vidaver

Journal of the Iowa Academy of Science: JIAS

This presentation raises questions of research needs and issues. Underlying assumptions are that only beneficial or useful microorganisms will be "released"; that extensive laboratory and contained experiments will have been done prior to introduction and live microorganisms can be confined within the areas of introduction. Evidence to support these assertions will be presented. Critical needs for progress in this area include: 1) Recognition that the nature of the product introduced into the environment is of primary significance, not how the organism was genetically altered or modified. 2) Recognition that microorganisms are introduced into the environment as part of our daily …

The Interaction Of Teacher And Student Social Styles And Learning Styles On Learning Outcomes Of The Basic Communication Course, Michael Smilowitz, Lynn A. Phelps

Basic Communication Course Annual

There has been considerable research that indicates the importance of the type and quality of teachers' communication. Too little of this research has considered the possibility of interrelationships between teacher's social and preferred learning styles with the social and preferred learning styles of students. This study examines students in basic communication courses for the effects of actual correspondence in styles as well as students' accuracy in describing the styles of their teachers. The results indicate that accurate perceptions of teachers' social styles influence course grades and actual correspondence influences student evaluations of the course.

A Unit On Relationship Termination For The Basic Course, Lynn A. Phelps

Basic Communication Course Annual

Basic interpersonal communication courses stress relationship development but seldom address the concept of relationship termination. If addressed, termination is often viewed from a negative perspective. Yet in today's mobile society, the concept that a person will continue to develop new relationships throughout their life without terminating any of their previous relationships is ludicrous at best. The purpose of this article is to suggest units on relationship termination which are appropriate for the basic communication course.

What We Know About The Basic Course: What Has The Research Told Us?, William J. Seiler, Drew Mcgukin

Basic Communication Course Annual

Research in the basic speech communication course is vital to our understanding of what we know about it, how it is administered and taught. The paper examines theoretical as well as empirical literature relevant to the basic course. Our examination suggests that the literature is deplete of a consistent base of knowledge on which to design the basic course. The paper concludes by discussing a proposal for systematic research to help provide a foundation for teaching and administering the basic course.

The Necessity Of Separating Idealized Accountability From Realized Accountability: A Case Study, Karen Greenberg

Basic Communication Course Annual

This essay presents the hidden distinction between the idealized accountability and the realized accountability of the basic communication course. It illuminates this difference as this difference is evidenced in the ethical dimension of the rhetoric of basic communication course instructors'manuals. Contrary to popular myth, the basic communication course does not aim to reinforce the importance of the creation and maintenance of students' or instructors' identities, but aims to reinforce the importance of the creation and maintenance of educational systems. That is, this course mystifies one type of social hierarchy rather than elucidating many.

A Comparison Between Psi-Based And Self-Contained Formats Of Instruction In The Introductory Speech Communication Course, Pamela L. Gray, Nancy L. Buerkel-Rothfuss, Richard W. Thomas

Basic Communication Course Annual

This study assesses differences between two instructional methods in a basic speech communication course: a modified Personalized System of Instruction (PSI) and a self contained format. Communication skills, communication apprehension, self-esteem, and academic achievement in, perceptions about, and satisfaction with the course are compared. Using t-tests to compare means and mean exchange scores, the PSI-based format was found to be more effective than the self-contained format. Comparing these data with an earlier study designed to compare the PSI-based format with more traditional lecture-recitation format, the self-contained approach appears to be a better alternative than the lecture-recitation for teaching the course, …

Ada Hayden: A Tribute, Duane Isely

Journal of the Iowa Academy of Science: JIAS

Dr. Ada Hayden was a member of the Iowa State College of Botany faculty, 1920-1950. Her floristic studies of the lake region in northern Iowa are possibly the most authoritative for any part of the state. Hayden was curator of the Iowa State herbarium, 1934-1950, and contributed immeasurably to its development. This research facility has recently been named the Ada Hayden Herbarium. In the sense that L. H. Pammel was father of the Iowa State park system, her bequest is the state preserves. After some 25 years as a conservation activist, she published descriptions of 22 prairie areas in ten …

Plant-Parasitic Nematodes In Iowa, Don C. Norton

Journal of the Iowa Academy of Science: JIAS

Ninety-nine species of plant-parasitic nematodes are recorded from Iowa. Twenty-seven are new state records. Most samples were collected from around maize or from prairies or woodlands. Similarity (Sorensen's index) of species was highest for the maize-prairie habitats (0.49), compared with maize-woodlands (0. 23), or prairie-woodland (0. 3 7) habitats. Nematode communities were most diverse in prairies with a Shannon-Weiner index (H') of 2.74, compared with 1.65 and 1.07 for woodlands and maize habitats, respectively. Evenness of species (J') was 0.41, 0.78, and 0.48 for maize, prairies, and woodlands, respectively.

Effects Of Intensive Training On Prolactin Responses To Submaximal Exercise In Males, A. C. Hackney, R. L. Sharp, W. S. Runyan, R. J. Ness

Journal of the Iowa Academy of Science: JIAS

The purpose of this study was to determine if serum prolactin responses to submaximal exercise were affected by 8 weeks of intensive training (5 cl/wk, 90 min/d 65-200% V0₂max). Nine males performed 90 minute continuous exercise bouts (cycle ergometry; 65% V0₂ max) at the end of 1, 4, and 8 weeks of training. Blood samples were obtained pre-training, and pre-, post-exercise. Significant differences were not seen in pre- and post-exercise prolactin levels at weeks 1 and 4. However, at week 8 the post-exercise prolatin was significantly greater than the pre-exercise levels (6.8 ± 0.9 vs 3.8 ± …

Additions To The Iowa Pteridophyte Flora - Iii, James H. Peck

Journal of the Iowa Academy of Science: JIAS

To prior reports on the studies of the Iowa pteridophyre flora, five taxa (Botrychium campestre Wagner & Farrar, Botrychimn matricariifolium A. Braun, CyJtopterislragilis (L) Bernh., Cystopteris laurentiana (Weath.) Blasdell, and Lycopodium inundatum L.) are added, along with 215 new county occurrence records for 39 taxa. Currently, the Iowa preridophyte flora consists of 70 taxa, supported with 1656 county occurrence records; only 72 (4%) of these records are based solely on collections made before 1950.

Semiquantitative Measurement Of Fission Produced Gamma Ray Radioactivity In Soils At Dubuque, Iowa, James A. Dockal, James A. Dockal Sr.

Journal of the Iowa Academy of Science: JIAS

Residual fission-product radionuclide contamination (fallout) in soils at Dubuque, Iowa was evaluated with an Exploration geometrics gamma ray scintillometer in 1985 and after the Chernobyl accident in 1986. Anomalous amounts of gamma ray radiation were found near where downspouts discharged storm runoff from the roof of a dwelling. The 1985 residual cesium-13 7 activity in the soils of the area was found to be 0.2 pCi/gram with an areal contamination of 16 ± nCi/m2. Activities associated with the soils near the discharge points of the downspouts ranged as high as 8 pCi/gram. This contamination seems to have occurred prior to …

The Vascular Flora Of Pilot Knob State Preserve, William C. Watson

Journal of the Iowa Academy of Science: JIAS

Pilot Knob State Preserve is a 365 acre (147 ha) area lying within the boundaries of Pilot Knob State Park. Located in north central Iowa near the northeast corner of Hancock County, this preserve resides on the eastern morainal system of the Des Moines Lobe left from the Wisconsinan glaciation. The vegetation of the preserve is primarily a deciduous woodland on rolling hills interspersed with wetland habitats in the hollows. Iowa's only floating bog is present in one of these hollows and supports numerous vascular plants uncommon to the state. Two species, Carex cephalantha (Bailey) Bickn. and Drosera rotundifolia L., …

Ecology Of Iowa Drosophila Ii. Lowland Forest And Sand Prairie, Neil J. Jennings, Robert D. Seager

Journal of the Iowa Academy of Science: JIAS

The seasonal abundances of Drosophila species collected from a lowland forest community and from a sand prairie community in northeastern Iowa are compared. With some important exceptions, the patterns seen in the lowland forest community were similar to what had been observed in a previous collection (Jennings et al. 1985). Fewer species and many fewer individuals were collected from the sand prairie community, although in general the patterns seen were similar to those of the lowland forest community. Strong evidence of microhabitat differentiation was seen in both communities. In contrast to our previous study, none of the seasonal abundance patterns …

Hybrid Performance Of Sorghum Parental Lines Developed By Mass Selection And S1 Yield Testing, K. R. Ess, R. E. Atkins

Journal of the Iowa Academy of Science: JIAS

Experiments were conducted co obtain information on the effects of two methods of developing parental lines from a random-mating population of sorghum (Sorghum bicolor L. Moench) on hybrid performance. Gridded mass selection for threshed panicle weight was used in developing IAP1R(M)C3: and a sister population, IAP4R(S1)C3, was advanced each cycle on the basis of grain yield of S₁ families in replicated yield trials. Hybrids with male parents developed by mass selection did not differ significantly for grain yield and panicles/plant from those with parents chosen on the basis of S₁ yield tests. The S₁-selection hybrids …

Synthesis And Antibacterial Studies Of Some 2-Furanthiocarboxyhydrazones, Xiaorong Li, Zoumin Sun, James C. Chang

Journal of the Iowa Academy of Science: JIAS

Seven 2-furanthiocarboxyhydrazones were prepared, 5-nitro-furaldehyde-2-furanthiocarboxyhydrazone from the reaction of 2-furanthiocarboxyhydrazide with 5-nitro-2-furaldiacetate and the others from the condensation of 2-furanthiocarboxyhydrazide with aldehydes: 2- furaldehyde, benzaldehyde, p-hydroxybenzaldehyde, o-methoxybenzaldehyde, o-vanillin, and salicylaldehyde. The seven 2-furanthiocarboxyhydrazones were tested for their antibacterial activities against Staphyloccocus aureus and Bacillus subtilis. 5-Nitro-2-furaldehyde-2- furanthiocarboxyhydrazone was found to display the strongest bacterotoxicity.
