AbstractThe purpose of this study was to determine if a relationship existed in healthy older adults between two psychological and physiological variables. The conceptual framework suggested that a relationship of psychological and physiological functions would facilitate positive adjustment to the stressors of aging. Life satisfaction represented psychological functioning; body temperature represented physiological functioning; body temperature represented physiological functioning. Because some evidence exists that normal temperature for older adults is lower than 98.6°F, an additional purpose was to determine if the sample had a normal body temperature lower than 98.6°F. Subjects were 174 healthy Caucasians aged 60-97. None were taking antibiotic, phenotiazine, cortisone, or reserpine containing drugs. Life satisfaction was measured using Neugarten's Life Satisfaction Index A (LSIA); body temperature was measured with an IVAC 821 oral electronic thermometer. Subjects rated perceived health on the Health Status Scale (HSS), and enumerated the past year's stressful life events on a modification of Holmes and Rahe's Social Readjustment Rating Questionnaire (SRRQ). Data were collected in winter and summer to determine if body temperature was different based on season. Statistical significance was p = .05. An ANOVA revealed no significant differences between winter and summer groups. The Pearson product-moment revealed no correlation between LSIA and TEMP. LSIA was significantly correlated with HSS and AGE; that is, subjects who were more satisfied with their lives considered themselves healthier, and were younger than other subjects. TEMP was significantly related only to SEX, indicating that females had higher temperatures than males. The mean temperature for all subjects, 98.24°F, was statistically different from 98.6°F, as were winter (98.32°F) and summer (98.17°F) group means. No difference was found between winter and summer mean temperatures, indicating that season of the year did not affect body temperatures in this sample. It was concluded that no psychophysiological relationship was found because body temperature may index only illness, not health. The mean temperature was not clinically different from 98.6°F most likely because these subjects were not taking drugs known to affect body temperature. A recommendation was that nurses evaluate each older client's temperature against his own normal, versus a universal normal.

Economic analysis of biofuels production in arid regionsRuskin, Helen Ann Kassander. (The University of Arizona., 1983)The objective of this study is to develop a model to evaluate the economic feasibility of biofuels production, and in particular to isolate the variables crucial to feasibility. The model constructed to define these variables is unique in its ability to accommodate a variety of plants and to integrate all portions of the production process; it was tested on a case study of a Euphorbia lathyris industry. The model minimizes costs of production to determine the best configuration for the industry. Total cost equals the sum of costs incurred in each segment of the process: growth, harvest, transport, and extraction. The solution is determined through a non-linear transportation- transshipment algorithm which describes production as a series of nodes and links. Specific application of the model was analysis of E. lathyris biofuel production in Arizona. Simulations were run examining the sensitivity of biocrude cost to changes in input parameters. Conclusions are summarized as follows. * No change in any single element can reduce final cost sufficiently to enable competitive production in the near future. * The major factor necessary to bring cost into range is improvement in biological yield. Two components of equal importance are tonnage produced per acre and percentage extractables recovered in processing. * Lowering cropping costs provided the most effective improvements of economic inputs. Perennial crops significantly reduced farm costs. * Transportation costs outweighed economies of scale in extraction; extractor location close to crops is more efficient than centralized. The cost minimization model was successfully used to isolate the critical factors for an E. lathyris industry in an arid region. Results determine that this industry would not be competitive in Arizona without dramatic improvements in yields and moderate changes in a combination of input costs. Viability is critically dependent on improvements in tonnage yield produced per acre and percent extractables recovered.

ENVIRONMENTAL EDUCATION EFFECTS ON PERCEPTION OF RECREATIONAL AND SCENIC QUALITIES OF FOREST BURN AREAS.TAYLOR, JONATHAN GOLDING. (The University of Arizona., 1982)The purpose of this study has been to test public perceptions of both scenic quality and recreational acceptability of southwestern ponderosa pine forests exibiting one-to-five years of recovery from both light and severe fire. Public fire-effects information documents were also constructed and tested. Appropriate ponderosa forest areas in Arizona were selected and randomly photographed. Population samples, drawn from Tucson, Arizona, first read fire-ecology or "control" information brochures and then rated forest scenes on 1-to-10 scales for scenic quality and for acceptability for selected forms of outdoor recreation. Respondents finally answered a short fire-knowledge, fire-attitude questionnaire. Ratings were subjected to SBE analysis (Daniel and Boster, 1976), and analysis of variance was applied to both ratings and questionnaire results. The clearest distinction drawn, for both scenic quality and recreational acceptability, is between light-fire and severe-fire effects. Light fire improves scenic quality for a 3-to-4 year period, while severe fire seriously detracts from scenic quality for an unknown length of time exceeding the 5-year period tested. Recreational acceptability is differentiated according to the recreational activity selected: camping is nearly twice as sensitive to severe fire effects as scenic quality, and is somewhat disrupted by light fire effects; picnicking is second-most impacted by severe fire effects; hiking or backpacking is affected by severe fire to about the same degree as scenic quality; nature study is least affected. Picnicking, hiking and nature study are not significantly affected by light fire. Provision of fire-effects information does not significantly affect scenic or recreational evaluation of forest burn areas. The fire-effects information brochures produced general "halo" effects on both fire knowledge and fire attitude in the groups sampled. Fire knowledge shifted toward the expert position that fire effects are less severe than generally believed. Fire attitude shifted toward the expert position of greater tolerance for fire in ponderosa ecosystems. Results show prescribed burning as generally acceptable. The results of this study demonstrate distinctions between affect (perceptual evaluations) and cognition (questionnaire response). Scenic and recreational evaluations emerge as clearly distinct entities.
