Dynamics Of Minority Education: An Index To The Status Of Race And Ethnic Relations In The United States, James E. Blackwell

Trotter Review

Throughout this century scholars and legal experts have devoted special attention to the issue of race and ethnicity as a determinant of life chances in the United States. Some of the more influential treatises in the social and behavioral sciences, many of which have become classics, addressed fundamental, derivative (and often more compelling) extensions of race and ethnicity. They focused on such topics as race-based group dominance, ethnic stratification, structural inequality based upon racial or ethnic identification, beliefs in inherent racial superiority and status privilege, class exploitation, the nature of prejudice, and the maintenance of power over groups defined as …

The Search For A Massachusetts Chancellor: Autonomy And Politics In Higher Education, Richard A. Hogarty

New England Journal of Public Policy

Political scientists have not devoted much attention to the politics of higher education. Their reluctance is hard to explain since the material for study is close at hand and the subject offers ample research opportunities. The search for a chancellor conducted by the Massachusetts Board of Regents in 1986 aroused considerable public attention and controversy. This case study examines that controversy along with the tensions that arise when academic and political forces collide. Few searches in academia are perfect and none is a morality play. This one proved to be no exception. This article is an attempt to reconstruct the …

Introducing Aids Education In Connecticut Schools, William Sabella

New England Journal of Public Policy

Most of the nation 's schoolchildren are not infected with the AIDS virus (HIV). Since AIDS is a preventable disease, no one need become infected. In order to protect themselves, everyone, including children, must understand exactly how HIV is and is not contracted. The message of prevention, however, is controversial, since it must include advice on safer sex and drug use.

In 1984, Connecticut was forced to face the issue of a child with HIV infection entering school. The state responded by creating guidelines for prevention of disease transmission in schools and by subsequently developing an AIDS curriculum. Obstacles to …

Biotechnology: A Dilemma For Land-Grant Institutions, A. David Kline

Journal of the Iowa Academy of Science: JIAS

There is at least a prima facie moral tension between universities asserting land-grant principles and simultaneously sponsoring biotechnology. The core of the problem is the likely deleterious economic effects of biotechnology on rural communities -- the very constituency whose welfare is supposedly promoted by land-grant institutions. Considered are a number of responses to this tension including efforts to show that the tension is only apparent or that it can be eliminated through various public policies. It is argued that these "solutions" fail.

The upshot is that if the land-grant label is to be taken seriously, those institutions should begin allocating …

Impact Of Biotechnology On Agriculture Productivity, Roger A. Kleese

Journal of the Iowa Academy of Science: JIAS

Biotechnology is a diverse array of technologies which today are in various stages of evolution and development. To understand them and the potential application of these technologies to agriculture, it is helpful to consider them in a historical perspective. In addition, it is important to understand the interdependence of biotechnologies on traditional, well developed technologies. The commercial development of biotechnology is more difficult than imagined even as recently as five years ago. Also, the problems being addressed generally demand a much better understanding of the physiology and biochemistry of the plant and animal systems under study. Nonetheless, there is a …

Predation By Ermine And Long-Tailed Weasels On Duck Eggs, Joseph P. Fleskes

Journal of the Iowa Academy of Science: JIAS

Ermine (Mustela erminea) and long-tailed weasel (M. frenata) predation on duck eggs was studied at Union Slough National Wildlife Refuge, Kossuth County, Iowa, 1984-85. Captive individuals of both species ate 2-4 duck eggs at a rate of 0.5-2 eggs per trial day. All eggs were moved but some were not opened. One hole, ringed with small fragments and "bite-outs'', was made in all eggs opened by captive weasels. In the field, the appearance of opened eggs, the pattern of egg loss and the amount of nest bowl disturbance were used to determine the number of nests depreciated by weasels. Egg …

Biotechnology: Impact On Iowa's Agricultural Economy, Dwight T. Thomas

Journal of the Iowa Academy of Science: JIAS

Agriculture has always been an important cornerstone of Iowa's economy. The highly publicized difficulties in the agricultural economy in Iowa have highlighted both the importance of agriculture and pitfalls when agriculture is hit by adverse conditions. Iowa's agriculture and agricultural infrastructure have a heritage characterized by the development of very efficient production technology and the early use of innovative ideas. The early adoption of hybrid corn is but one example of the acceptance new technology. Today more than ever before there is a need for improved profitability and for the possibility of diversification of agricultural products in Iowa.

The following …

Benthic Macroinvertebrate Habitat Associations Of The Channelized Middle Missouri River, James B. Barnum, Roger W. Bachmann

Journal of the Iowa Academy of Science: JIAS

Benthic macroinvertebrates associated with navigation structures (dikes, dike pools, revetted banks) and abandoned channels on the Missouri River at the Iowa-Nebraska border were sampled in June, August, and October 1983 to determine the invertebrate community structure of these habitats. Invertebrate densities were greatest in the abandoned channel habitat (to over 13,000/m²), while diversities were greatest in the dike and revetment habitats. Greater habitat diversity contributed to greater organism diversity in the dike and revetment habitats while sediment homogeneity and stability presumably contributed to greater organism densities in the abandoned channel habitat. Dike pools had turbulent eddy currents, which …

A New Name For A Continuing Publication, Marilyn D. Bachmann, Roger W. Bachmann

Journal of the Iowa Academy of Science: JIAS

With this issue, the former Proceedings of the Iowa Academy of Science becomes The Journal of the Iowa Academy of Science, a change which coincides with the l00th annual meeting of the Academy. This concludes a process started in 1971 when the Proceedings became a quarterly periodical which also included papers that had not been presented at the previous annual meeting.

An Interpretative History Of The Proceedings Of The Iowa Academy Of Science, Don C. Norton

Journal of the Iowa Academy of Science: JIAS

The Proceedings of the Iowa Academy of Science was first published in 1887 and has continued yearly except for 1905. Business reports and contributed papers constituted most of the volumes. Publication of symposia has become more popular in recent years. Financial and mechanical problems have caused strains at rimes, but these have largely been solved after publication became independent of the State Printer.

Solvent Effects In Room Temperature Phosphorescence, Shane J. Helsenbeck, Catherine Haustein

Journal of the Iowa Academy of Science: JIAS

Room temperature phosphorescence (R TP) analysis is a technique in which solutions containing organic phosphors are applied to filter paper and dried in the absence of oxygen. Adsorption to the paper inhibits molecular vibrations and promotes phosphorescence. Although the solvent must be removed by volatilization before phosphorescence can occur, it appears that the nature of the solvent affects the intensity of the resulting phosphorescence. We examined the room temperature phosphorescence of p-aminobenzoic acid which had been dissolved in water, organic solvents, or mixtures of water and organic solvents. It was found that solvent volatility had little correlation with RTP intensity …

A Vascular Flora Of The Swaledale Railroad Prairie In North Central Iowa, Thomas L. Eddy

Journal of the Iowa Academy of Science: JIAS

"Railroad prairies" are remnant native grasslands that grow along railroad right-of-ways. The Swaledale railroad prairie, which is in north central Iowa, occurs along the Chicago and Northwestern Railroad Company right-of-way in Cerro Gordo County.

The railroad right-of-way and an abandoned sand pit, which lies adjacent to the railroad embankment, harbor a collection of tallgrass prairie remnants. The sand pit supplied earthen fill which was used to elevate the original railroad embankment, circa 1887. It is noteworthy that the method of excavation for fill material helped to preserve earthen knolls that are covered with original tallgrass prairie.

Plant collections were acquired …
