Relationships of Selected Factors to Library Use and Attitudes Among Students in a College of Business Administration

Drake, Betty S. (Betty Sue) 08 1900 (has links)
This study was an inquiry into the use of the library and attitudes toward librarians and libraries by 484 academic business majors. Data was collected by means of a questionnaire administered to a sample of all business majors at one university. Demographic and social status data, based on Hollingshead's categories, and responses to statements concerning library use, librarians, and libraries were analyzed by means of the Kolmorogov-Smirnov Test, the Median Test and Spearman correlation coefficients.

A Rhetorical Analysis of Major Oil Companies' Advertisements in 1990 : A Semiotic Approach

Barton, Mica Waggoner 05 1900 (has links)
This study demonstrates how discourse is used to construct popular myths. This study analyzes magazine advertisements used by businesses in overcoming the rhetorical problem posed by a public opinion that blamed them for environmental problems. This study shows how businesses used advertisements to construct a popular myth that businesses were doing their part in overcoming the environmental crisis.

Matador

Patino, Julio 05 1900 (has links)
Matador is an opera scored for orchestra, mixed chorus and soloists (mezzosoprano, 3 tenors, 2 baritones). The work is in one act divided into two main sections. Each of these sections is divided into subsections. The libretto is aphoristic in nature and dictates the form of each of these subsections. The division into two parts also serves as a means to evoke a sense of hopelessness of emotions in the first and a transforming disposition that culminates in a jubilant song in the second.

Conformational Analogs of Some Phytoactive Compounds

Skelton, Wm. Paul 08 1900 (has links)
In an effort to determine if there is a specific conformational structure which is most effective at the appropriate active physiological site, the synthesis of a group of sterically restricted analogs was undertaken. A portion of the polymethylene carbon skeleton of glutaric acid was replaced by selected aromatic carbons in benzenedicarboxylic acids to produce a series of ridged conformers, and the relative plant growth regulating properties of these derivatives were determined.

Public School Choice : An Impact Assessment

Davis, Casi G. (Casi Gail) 12 1900 (has links)
The goal of this thesis is to understand the consequences of educational choice in the public school system. The research takes place in San Antonio, Texas. The research encompasses meaningful comparisons between three sets of low income students and their families: 1) those who chose to remain in their attendance-zone school, 2) those who enrolled in the multilingual program, and 3) those who applied to the multilingual program but were not admitted because of space limitations.

Lipids and Phospholipase Activity of Vibrio Cholerae

Brian, Buford Leo 08 1900 (has links)
One purpose of this investigation is to determine the fatty acid and lipid content of typical Vibrio cholerae cells. The comparison of cholera lipid constituents with those of closely-related bacteria might be of taxonomic value. Furthermore, chemical characterization of the cholera vibrio could provide useful criteria for identification of these disease-producing microorganisms.

Effects of External Electric Fields on Light Transmittance in Isolated Crayfish Nerves

Northcutt, Brian S. W. 12 1900 (has links)
Acute effects of a pulsed external electric field (PEEF) at 20 V/cm and a d.c. EEF at 90 V/cm on light transmittance in an isolated compound crayfish nerve was measured. In a third series, the nerve was pre-treated with the Na+ channel blocker tetrodotoxin (TTX). A PEEF produced an irreversible increase in the variation of light transmittance in normal nerves but a reversible increase in TTX treated nerves. This data was statistically insignificant. The d.c. EEFs produced a reversible and statistically significant enhancement of variation in light transmittance in both untreated and TTX-treated nerves. The findings may be due to either (1) an alteration in the ion/fluid flux within the nerve or (2) a physical alteration of protein molecules in the membranes.

Passive Dispersal of Algae and Protozoa Internally and Externally by Selected Aquatic Insects

Solon, Bernard M. (Bernard Michael), 1932- 12 1900 (has links)
This investigation was concerned with three aspects of the problem of passive dispersal of algae and protozoa by aquatic insects: the role of odonates in passive dispersal of viable small aquatic organisms, the passage of viable algae and protozoa through digestive tracts of field-collected herbivorous and carnivorous aquatic insects, and the viability duration of selected algae, during insect transport under monitored conditions.

Organizational Support Systems for Team-Based Organizations: Employee Collaboration through Organizational Structures

Hall, Christopher Aaron, 1964- 08 1900 (has links)
The purpose of this study was to examine relationships between organizational support and Effectiveness, Empowerment, and team characteristics. Support was operationalized by nine systems: Executive Management, Direct Supervision, Group Design, Performance Definition, Performance Review, Training, Rewards, Information, and Integration. Support was rated in two ways: how important is support for performing work (Importance scales), and how does support describe work environments (Presence scales).

A Unifying Version Model for Objects and Schema in Object-Oriented Database System

Shin, Dongil 08 1900 (has links)
There have been a number of different versioning models proposed. The research in this area can be divided into two categories: object versioning and schema versioning. In this dissertation, both problem domains are considered as a single unit. This dissertation describes a unifying version model (UVM) for maintaining changes to both objects and schema. UVM handles schema versioning operations by using object versioning techniques. The result is that the UVM allows the OODBMS to be much smaller than previous systems. Also, programmers need know only one set of versioning operations; thus, reducing the learning time by half. This dissertation shows that UVM is a simple but semantically sound and powerful version model for both objects and schema.
