Construct Use and Self-Aspect Change in Recovery From Coronary Artery Bypass Graft Surgery: a Personal Construct Analysis

Construct Use and Self-Aspect Change in Recovery From Coronary Artery Bypass Graft Surgery: a Personal Construct Analysis

Date: May 1992
Creator: Zolten, Avram J. (Avram Jeffery)
Description: Cognitive ratings that use bipolar constructs based upon similarity and contrast have been shown to be biased towards the similarity pole in approximately a 62/38 ratio. This bias has also been known to shift in the contrastive direction for individuals who have psychiatric problems. This quantitative measure of cognitive change has a potential for characterizing cognitive changes that occur during the disease process, including recovery from disease. The present study investigated changes in self-aspect ratings and bipolar construct use in adult male veterans who had undergone coronary artery bypass graft surgery. Results indicated that treatment subjects' self-aspect and construct ratings were more negative than controls'. Results also indicated that all subjects rated core interpersonal self-aspects closest to the expected bias, while self-aspects related to cardiac recovery problems were rated in the most contrastive direction. The results finally suggested that the greatest degree of change for the treatment subjects were in emotionally generated constructs. The results suggested a preliminary validation for characterizing cognitive changes in the disease process by measuring shifts in bipolar construct ratings.

Factors Associated with Salespersons' Use of Influence Tactics and Their Outcomes : An Exploratory Study

Factors Associated with Salespersons' Use of Influence Tactics and Their Outcomes : An Exploratory Study

Date: May 1992
Creator: Nonis, Sarath A. (Sarath Alban)
Description: The use of influence tactics by sales representatives appears to be related to a number of latent constructs and factors such as, manifest needs, role conflict and role ambiguity, and perception of sales managers' power bases. However, such relationships have not been examined by researchers. These relationships were examined in this study in an effort to improve the current level of understanding of causes and results of the use of influence tactics in a sales environment. The contention of this study was that individuals in work settings engage in a variety of influence tactics, and that the type of influence tactics used are influenced by factors such as personal characteristics of the salespersons, the nature of goals to be achieved, the salespersons' perceptions of their superiors' power bases, and the nature and complexity of the dyadic relationship that exists between supervisor and subordinates.

A History of the Administrative Development and Contributions of the Federation of North Texas Area Universities, 1968-1991

A History of the Administrative Development and Contributions of the Federation of North Texas Area Universities, 1968-1991

Date: May 1992
Creator: Morris, Lucille Darline
Description: The Federation of North Texas Area Universities was mandated by the Coordinating Board of the Texas College and University System on 3 December 1968, and this consortium was given legal empowerment by the Texas State Legislature. The three federated Universities--North Texas State University, Texas Woman's University and East Texas State University--developed a plan of cooperative action to maximize use of available resources, a plan which included sharing facilities and faculty as well as developing joint program offerings. At a time in history when educational institutions were obliged to maximize their resources, minimize their expenditure, and eliminate duplication, the consortium was an innovative approach to higher education as well as an interesting alternative to having degree programs cut and funding diminished.

Locational Determinants of Real Estate Valuation: an Analysis of Spatial Autocorrelation in the Hedonic Pricing of Real Estate

Locational Determinants of Real Estate Valuation: an Analysis of Spatial Autocorrelation in the Hedonic Pricing of Real Estate

Date: May 1992
Creator: Shampton, John F.
Description: Recent studies of the valuation of real estate have concentrated on the use of hedonic pricing techniques in which the implicit prices of the component characteristics of an asset are inferred from the observed sale price using regression analysis. All of these studies include as explanatory variables one or more locational factors, such as distance to the central business district, as proxies for the effect that location has on the utility of land. In this research, the explicit consideration of the location of real estate in terms of the geographic or Cartesian coordinates (spatial attributes) of observed sales is shown to be a potential substitute for such proxies, either wholly or in part. Such use of spatial attributes could improve the usefulness of the hedonic methodology while at the same time significantly reducing cost and eliminating sources of error.

Molecular and Kinetic Characterization of the Aspartate Transcarbamoylase Dihydroorotase Complex in Pseudomonas putida

Molecular and Kinetic Characterization of the Aspartate Transcarbamoylase Dihydroorotase Complex in Pseudomonas putida

Date: May 1992
Creator: Schurr, Michael J. (Michael John)
Description: Aerobic Gram negative bacteria such as Pseudomonas putida were reported to possess class A ATCases and to have a M.W. of 360 kD. The nucleotide sequence of the P. putida pyrBC was determined to answer this question once and for all. The expected regulatory gene was not found. It is shown that the P. putida pyrB gene is overlapped by pyrC by 4 bp. The P.putida pyrB is 1005 bp (335 aa) in length and the pyrC is 1275 bp (425 aa) long. Both of these genes complement E. coli mutants with their respective genotypes. Another finding borne out from the sequence is an effector binding site at the N-terminus of pyrB of P. putIda. The binding site shows that effectors compete with carbamoylphosphate for the active site. In this dissertation, it is shown that the ATCase of P.putida is a trimer of M.W. of 109 kD (3 x 36.4 kD) and that the gene encoding pyrB is overlapped by the pyrC gene which encodes DHOase. It is also shown that the pyrBC encoded enzymes copurify as a dodecameric complex with a M.W. of 484 kD.

Outliers and Regression Models

Outliers and Regression Models

Date: May 1992
Creator: Mitchell, Napoleon
Description: The mitigation of outliers serves to increase the strength of a relationship between variables. This study defined outliers in three different ways and used five regression procedures to describe the effects of outliers on 50 data sets. This study also examined the relationship among the shape of the distribution, skewness, and outliers.

Parallels in the Development of Electronic and Percussion Music and an Examination of Performance Problems in Lejaren Hiller's Machine Music for Piano, Percussion and Two-Channel Tape Recorder with Three Recitals of Selected Works of Rolnick, Kessner, Xenakis, Winsor, Niimi, and Others

Parallels in the Development of Electronic and Percussion Music and an Examination of Performance Problems in Lejaren Hiller's Machine Music for Piano, Percussion and Two-Channel Tape Recorder with Three Recitals of Selected Works of Rolnick, Kessner, Xenakis, Winsor, Niimi, and Others

Date: May 1992
Creator: Smith, Jeffrey B., 1957-
Description: This study traces the significant developments in the late nineteenth and early twentieth centuries which led to the development of electronic music and increased writing for percussion. Whether by coincidence or premeditation, the field of percussion in Western culture and electronic music share many parallel aspects in their history. Carlos Chavez, Edgard Varese and John Cage foresaw a time when electronic music would allow composers to realize compositions with ease, provide new sounds to the spectrum of possible material for pieces and aid in the conception of works. Significantly, these same composers were important figures in the development of percussion composition. In many ways, Lejaren Hiller's Machine Music can be seen as a culmination of the developments which had been taking place in the history of electronic music and percussion music. A product of the innovations in both fields, it poses some formidable problems for the performers. This study will give some background into its composition, examine its structure and deal with its performance problems.

Using Normal Deduction Graphs in Common Sense Reasoning

Using Normal Deduction Graphs in Common Sense Reasoning

Date: May 1992
Creator: Munoz, Ricardo A. (Ricardo Alberto)
Description: This investigation proposes a powerful formalization of common sense knowledge based on function-free normal deduction graphs (NDGs) which form a powerful tool for deriving Horn and non-Horn clauses without functions. Such formalization allows common sense reasoning since it has the ability to handle not only negative but also incomplete information.
