Nitrogen Balance for a 23-Square Mile Minnesota WatershedJohnson, Jack D.; Office of Arid Land Studies, University of Arizona, Tucson (Arizona-Nevada Academy of Science, 1971-04-23)The nitrogen balance of a watershed near the city of New Prague, Minnesota was evaluated as part of an overall study on lake and stream eutrophication. Although the n-balance of a humid Midwest watershed cannot be expected to be identical to that of an arid watershed, the processes are the same and differences should be mainly quantitive. Sources of input and causes of depletion are reviewed for 4 points in the nitrogen cycle: the atmospheric zone, the soil-atmosphere interface, the plant-root and soil-water zone and the surface water zone. In the New Prague watershed, commercial fertilizer and bulk precipitation were the major sources of input, contributing, respectively, 53% and 34.4% of the total input of 2.34 million lb/yr. Crop yield and soil or groundwater storage contributed 52.1% and 20.4% of non-enrichment depletions. The closeness of the values of crop yield and commercial fertilizer application was an unfortunate coincidence and is certainly not an indication that the entire fertilizer supply was taken up cry crops. In an arid environment, free from fertilized agriculture, bulk precipitation probably provides the major source of nitrogen compounds.
Discriminating clinic from control groups of deaf adults using a short form of the Brauer-Gallaudet American Sign Language translation of the Minnesota Multiphasic Personality Inventory.Eldredge, Nancy; Riley-Glassman, Nathan David.; Organist, James; Johnson, Bob (The University of Arizona., 1989)This study tested whether an American Sign Language (ASL) MMPI short form, the Brauer-Gallaudet MMPI-168 (B-G MMPI-168), could discriminate between groups of deaf adults with and without psychopathology. B-G MMPI-168 and MMPI-168 profiles were also compared in deaf adults without a history of psychopathology. Independent variables were history of mental health treatment, language of administration and reading ability. Dependent variables were MMPI-168 and B-G MMPI-168 validity and clinical scale evaluations. Fifty-nine deaf adults from the community and outpatient counseling services completed demographic information on a questionnaire developed especially for this study. Subjects were divided into Clinic and Control groups based on history (Clinic) or no history (Control) of mental health treatment. Reading Comprehension scores (Advanced Stanford Achievement Test) of Control subjects determined placement in Control (I), (11th grade and above) and Control (II), (6-11 grade) groups. All subjects took the B-G MMPI-168. Control subjects took the MMPI-168 at home within two weeks. Ten dollars was earned for participation. Results indicated that Clinic and Control (II) groups were not accurately discriminated by B-G MMPI-168 profiles. The "hit rate" for the Clinic group was 96.5 percent, but only 40.0% of the Control subjects were correctly classified as Not Disturbed. This version of the B-G MMPI-168 was judged unacceptable for clinical use until items are revised. Level of reading ability was not a significant factor in the clinical validity of the MMPI-168. The "hit rates" of correct classification of Control (I) and Control (II) subjects as Not Disturbed, 58.8 and 46.2, respectively, were unacceptable. Language of administration was not a significant factor in the clinical validity of Control group "168" profiles. B-G MMPI-168 profiles showed more psychopathology than MMPI-168 profiles, but both tests had unacceptably high percentages of Control subjects classified as Disturbed. Revision of B-G MMPI-168 items was recommended so that profiles can accurately discriminate between Clinic and Control groups. The MMPI-168 was recommended for use as part of a personality assessment battery for deaf adults having 12th grade equivalent or higher reading level.
