This investigation focuses upon two major problems. The first problem is to determine what effect the inclusion of economics in the mathematics curriculum will have upon student attitudes toward and understanding and retention of economics and mathematics. The second problem is to determine whether different methods of instruction will result in significantly different levels of student attitudes toward and understanding and retention of economics and mathematics.

This study was designed to evaluate the planning process in hospitals. The specific problem of concern in this investigation was the pressing need for planning by hospitals that focuses upon the constraints imposed by governmental regulation and by resource limitations. The purpose of this study was to identify marketing concepts that have application to the hospital planning process and to make a general evaluation of their current utilization in North Central Texas area.

According to Treisman (Treisman and Schmidt, 1982) feature detection occurs in parallel, while the correct integration of detected features into an object requires focal attention. She has proposed that in the absence of attention, subjects will perceive "illusory conjunctions", or invented objects constructed out of features actually present in a display. The present experiments were designed to examine how the presence of expectations might affect the feature integration process and the construction of illusory conjunctions. The results of these experiments suggest that expectations do affect the perception of simple objects: subjects make more illusory conjunctions in the absence of expectations, and the perception of expected objects is the most accurate. However, the data indicate that expectations do not exert this influence by guiding the feature integration process, because subjects do not tend to construct expected objects out of features appearing in a display. As a result, it is likely that expectations are influential not by determining the construction of object files, but by speeding up the identification of the features of expected objects, so that focal attention can be applied, and object files constructed, more efficiently. As a result, the perception of expected objects can be accurately accomplished in a shorter amount of time. / Arts, Faculty of / Psychology, Department of / Graduate

Infectious diarrhea results in 2 to 5 million deaths worldwide per year, and treatments that are safe, effective, and readily available are under investigation. The field of medicinal ethnobotany focuses on plants that are used by different cultural groups for treating various diseases and evaluates these plants for efficacy and cytotoxicity. In the present study, ethnobotanical research was conducted with Central Anatolian villagers in Turkey. Folk concepts and etiologies surrounding diarrhea were analyzed, as were salient plant-based remedies for diarrhea. Reviewing the literature, 91 plant species were described as anti-diarrheal in all of Turkey. In Central Anatolia, villagers described 35 species. For continued research via bactericidal and bacteriostatic bioassays, 15 plants were selected. Methanolic and aqueous extracts of medicinally used plant parts were evaluated for inhibitory properties against 10 diarrhea-causing bacteria in the first bioassay, and later 21 bacteria in a second assay utilizing spectrophotometry. The cytotoxic properties were also evaluated in an Alamar Blue Assay using HepG-2, PC-3, and SkMEL-5 human cell lines. While several extracts showed bactericidal and bacteriostatic properties, the methanolic extract of R. canina galls inhibited the most bacteria at the lowest concentrations. They were not cytotoxic. Thus, R. canina methanolic gall extracts were selected for bio-assay guided fractionation. Antibacterial activity was maintained in the third fraction which was composed of almost pure ellagic acid. The bioassay was repeated with standard ellagic acid, and the polyphenol retained potency in inhibiting multiple bacterial strains. Several other extracts showed promise for safe, effective anti-bacterial remedies for diarrhea.

The present study attempted to investigate the relationship between a subject's degree of dogmatism and his attitudes towards the different theoretical positions held by B. F. Skinner and Carl Rogers regarding the control of man. This study utilized selective retention as an indicator of subjects' attitudes. No significant difference was found between Skinner's and Rogers' on their retention of high, medium, and low dogmatism groups. There was also a non-significant correlation between subjects' scores on the retention of Sinner's and Rogers' concept and subjects' dogmatism scores.
