Faculty Turnover at American Colleges and Universities: Analyses of AAUP Data

This paper uses institutional level data collected by the American Association of University Professors as part of their annual survey of faculty members\u27 compensation to analyze faculty turnover. Analyses of aggregate data over almost a twenty-year period highlight how remarkably stable faculty retention rates have been nationwide and how little they vary across broad categories of institutions. Analyses of variations in faculty retention rates across individual institutions stress the role that faculty compensation levels play. Higher levels of compensation appear to increase retention rates for assistant and associate professors (but not for full professors) and the magnitude of this effect grows larger as one moves from institutions with graduate programs, to four-year undergraduate institutions, to two-year institutions

An Analysis of the Program for Education Professions Development Act, Part E, Fellowship Students at Utah State University

From the time of the first school through the current schools of today, one of the greatest concerns of educators has been the development of curriculums. Among the most important educational policies of schools are those pertaining to curriculum. (Kirst and Decker, 1972, p. 28) This concern has been echoed by many educators across the country including those at Utah State University. At Utah State the responsibility of the curriculum for the Education Professions Development Act, Part E, program (EPDA) belongs to the Business Education Department. The fiveyear old EPDA, Part E, program at Utah State University has been deeigned to meet the needs of master degree level students in preparation for business oriented positions at post-secondary institutions

How Would Universities Respond to Increased Federal Support for Graduate Students?

[Excerpt] This paper has demonstrated that doctorate-producing universities respond to changes in the number of FTSEG students supported on external funds by altering the number of FTSEG students that they support on institutional funds. While institutional adjustment to changes in external support levels appears to be quite rapid, in the aggregate the magnitude of these responses is quite small. A increase of 100 in the number of FTSEG students supported by external funds is estimated to reduce the number supported on institutional funds by 22 to 23. Since some of the institutional funds that are saved may be redirected to support graduate students in the humanities and other fields not represented in the data, the total effect of such a policy change on institutional support for graduate students is probably somewhat smaller

Globular Cluster Systems and the Missing Satellite Problem: Implications for Cold Dark Matter Models

We analyze the metallicity distributions of globular clusters belonging to 28 early-type galaxies in the survey of Kundu & Whitmore (2001). A Monte Carlo algorithm which simulates the chemical evolution of galaxies that grow hierarchically via dissipationless mergers is used to determine the most probable protogalactic mass function for each galaxy. Contrary to the claims of Kundu & Whitmore, we find that the observed metallicity distributions are in close agreement with the predictions of such hierarchical formation models. The mass spectrum of protogalactic fragments for the galaxies in our sample has a power-law behavior, with an exponent of roughly -2. This spectrum is indistinguishable from the mass spectrum of dark matter halos predicted by cold dark matter models for structure formation. We argue that these protogalactic fragments, the likely sites of globular cluster formation in the early universe, are the disrupted remains of the "missing" satellite galaxies predicted by cold dark matter models. Our findings suggest that the solution to the missing satellite problem is through the suppression of gas accretion in low-mass halos after reionization, or via self-interacting dark matter, and argue against models with suppressed small-scale power or warm dark matter.Comment: 28 pages, 19 postscript figures.

Asbestos exposure and mesothelioma in South Africa

Objectives. To describe the exposure experiences of South African mesothelioma  cases, with emphasis on the contribution made to the caseload by different fibre  types, the proportion of subjects with no recall of asbestos exposure and only environmental contact, and the importance of putative causes other than asbestos.Design. A multicentred case-control study.Subjects and setting. 123 patients with mesothelioma interviewed by trained  interviewers in study centres established in  Johannesburg, Kimberley, Pretoria, Bloemfontein, Cape Town and Port Elizabeth.Results. A convincing history of asbestos exposure was obtained in the overwhelming majority of cases (only 5 cases had unlikely asbestos exposure). Twenty-three subjects had worked on Cape crocidolite mines, 3 at Penge (an amosite mine), 3 on mines  producing amosite and Transvaal crocidolite and 1 on a Transvaal crocidolite mine. Exclusively environmental exposure  accounted for at least 18% of cases; 91% of these cases (20/'22 subjects) had had contact with Cape crocidolite. There was a relative paucity of cases linked to amosite and no convincing chrysotile case. Non-asbestos causes occur rarely, if at all; in South  Africa.Conclusion. The preponderance of crocidolite cases, followed by amosite and then chrysotile cases, is consistent with the view that there is a fibre gradient of mesotheliomagenic potential for South African asbestos (crocidolite > amosite >chrysotile)

Wheat Stem Maggot (Diptera: Chloropidae): An Emerging Pest of Cover Crop to Corn Transition Systems

The wheat stem maggot (Meromyza americana Fitch) (WSM) is a minor pest of wheat, rye, and other grasses. In 2017, growers in Nebraska reported dead center whorls and excessive tillering in early-season cornfields that followed wheat or rye terminated after planting corn. A survey was conducted to evaluate the risk factors for this insect in cover crop to corn transition systems. In each field, management practices and the percentage of injured plants were recorded. Symptomatic corn plants were collected from each field and dissected to determine larval and plant characteristics. In a few cases, small patches of a field were planted to a cover crop to manage soil erosion, and injured plants were only found where the cover crop was present. From these observations, the hypothesis is that terminating a cover crop after planting corn allowed the WSM larva to move from the dying cover crop to corn to complete its development. Cornfields infested with WSM had a frequency of injured corn plants from 0 to 60% with yield losses estimated at 30 bushels/acre. This paper provides the first detailed documentation of WSM injury in corn and addresses important management practices that may have influenced this uncommon situation
