Part 1. Investigation of Aluminum Amino Acid Complexes; Part 2. Structural Studies of Aluminum Chalcogen Bonds

Part 1. Investigation of Aluminum Amino Acid Complexes; Part 2. Structural Studies of Aluminum Chalcogen Bonds

Date: May 1996
Creator: Gravelle, Philip W. (Philip Wyn)
Description: Five different complexes of aluminum and amino acids have been synthesized and characterized. Reaction between aluminum halides and amino acids that do not contain either a carboxylate or a hydroxy group in the side chain produce complexes of the general formula, [Al(amino acid)_n(halide)_3-n]_m. The most prevalent form of this form of complex is where n = 2, and an example of this in which the halide is replaced by hydroxide ligand has been structurally characterized. The complex for which n = 3 may be obtained by employing a large excess of acid, and that for which n = 1 may be obtained by employing either equimolar conditions or an excess of aluminum halide. Reactions of aluminum halides with amino acids that contain either a carboxylate or hydroxy-containing side chain may result in complexes in which the side-chain is also bound. These proved impossible to characterize fully in the case of aspartic acid. For serine, however, a complex in which the amino acid binds in a chelating fashion through both the carboxylate and hydroxy groups was isolated. It was possible to form complexes when utilizing aluminum alkyls as the metal source. However, these complexes could only be isolated when the reactivity ...

Economic Impact of Hospitals: the Case of Baylor Regional Medical Center at Grapevine.

Economic Impact of Hospitals: the Case of Baylor Regional Medical Center at Grapevine.

Date: August 2004
Creator: Graves, Jennifer M.
Description: This report analyzes the economic impacts of the Baylor Regional Medical Center at Grapevine, Texas. The economic impacts are analyzed using the IMPLAN impact modeling system developed by the Minnesota IMPLAN Group. The analysis evaluates construction activities by Baylor-Grapevine as well as procurement spending and employment. Additionally, the impact of ancillary facilities surrounding Baylor-Grapevine and the impact of patient visitor spending is also reviewed. Total recurring impacts of procurement spending at Baylor-Grapevine, employment at Baylor-Grapevine and its ancillary facilities, and visitor spending will generate over $227 million in economic activity for the Dallas/Fort Worth Metroplex. This activity will support more than 3,300 direct, indirect, and induced jobs paying over $138 million in annual earnings.

Supply Chain Network Evolution: Demand-based Drivers of Interfirm Governance Evolution

Supply Chain Network Evolution: Demand-based Drivers of Interfirm Governance Evolution

Date: August 2007
Creator: Gravier, Michael J.
Description: Which form of exchange governance performs better in a dynamic environment? This remains an unanswered question in the transaction cost analysis (TCA) and relational exchange literatures. Some researchers purport that transactional governance provides superior performance by providing firms the flexibility to change suppliers. Others suggest that relational governance leads to superior performance because of the willingness of both parties to adapt. Reviews of TCA have turned up ambivalent empirical findings with regard to the effects of uncertainty despite a track record of strong empirical support for other predictions. Because most of TCA and relational exchange theories' predictions enjoy strong support, this research builds upon these theories to propose a theoretical modeling framework for a dynamic environment in a supply chain network (SCN) setting. This dissertation extends TCA and relational exchange to a dynamic, network environment. It uses the approach of building a simulation in order to study in detail the relationship between key exchange factors and the selection of transactional and relational exchange governance over time. This research effort extended TCA theory with a complex adaptive model of supply chain network governance evolution that attempts to link environmental, network, production, firm and exchange factors in a continuously evolving loop. The ...

The Relationships Among Whistle-blowing, Retaliation, and Identity: a Narrative Analysis

The Relationships Among Whistle-blowing, Retaliation, and Identity: a Narrative Analysis

Date: May 2012
Creator: Gravley, Dianne Yvonne
Description: Existing whistle-blower research has found that retaliation affects the whistle-blowing process. However, there is little literature focusing on the personal and emotional effects that retaliation can have on the whistle-blower’s life. Furthermore, while whistle-blowing has been studied in various organizational contexts, both public and private, virtually no research exists on whistle-blowing in the context of the public school system. This study examines the effects of the whistle-blowing process, specifically the effects of retaliation, on the life of the whistle-blower through a narrative identity construct in the context of the Texas Public School System. This study utilizes narrative analysis to understand the relationship between retaliation and the whistle-blowers’ narrative identity. the analysis reveals that whistle-blowers’ decisions to disclose instances of wrong-doing are motivated by their desired narrative identities. Furthermore, this study shows that retaliation has the greatest effect when it directly attacks the whistle-blowers’ identities.

Hard and Soft

Hard and Soft

Date: December 2000
Creator: Gray, J. Christensen
Description: The purpose of this investigation is to explore the possibilities of manipulating clay in three distinct ways to effectively show that clay objects were at one time moist and pliable. The techniques used are faceting while wet, manipulating a variety of additions, applying different glazing techniques, and three separate firing methods. In addressing the problem, the following concerns were considered: (a) Which of the pieces made best expresses my aesthetic concerns? (b) Which firing method, oxidation, reduction or atmospheric, best illustrates these concerns? (c) Which glazing technique was most successful? In an attempt to explore and solve these problems, a series of twenty pieces were produced. A visual record of slides showing individual pieces were made to demonstrate the differences and similarities between firing methods.
