Bonding Studies in Group IV Substituted n,n-dimethylanilines

Description: The purpose of the present work is to study the effects of the trimethylsilyl and trimethylgermyl substituents on the N,N-dimethylamino ring system. Both ground and excited state interactions were studied and their magnitudes determined. The experimental data were then used in conjunction with molecular orbital calculations to differentiate among, and determine the importance of, d-p bonding, hyperconjugation or polarization of the trimethylsilyl group on the ground and excited state bonding.

Does Underwriter Size Matter? Only Within the Right Context

Description: The initial matching relationships between underwriters and bonds/issuing firms and the certification quality of underwriters, as determined by changes in the issuing firm’s financial strength post issue, are the two primary research topics in this dissertation. Based on total underwriter syndicate market share, two distinct categories, low market power (LMP) syndicates and high market power (HMP) syndicates were defined. Firm financial strength is examined based on a new factor developed in this research. A comparison of the two underwriting categories, or pools, indicates that the HMP underwriters take on firms of lower initial financial strength and additionally, the issuing firms decline more in financial strength two years following bond issuance than do firms using LMP underwriters. Notwithstanding these results, the more interesting findings are the relationships within each of these pools. In the LMP pool of underwriters, financially stronger firms used the larger LMPs to underwrite their bonds, while the weaker firms used smaller LMPs. In contrast, among HMP underwriters, the largest HMPs aligned with the firms of relatively lower financial strength. The relationships in both pools reverse when changes in financial strength are examined. Larger LMPs are associated with greater issuing firm financial decline while larger HMPs correlate with lower levels of decline in firm financial strength. Divergent patterns in initial underwriter-issuer matching and underwriter certification found in this research indicate that there are true differences in the “small” underwriting syndicates as compared to the larger syndicates. These patterns should be considered by both issuing firms and investors as both constituencies contemplate the corporate bond market.

The Past, Present, and Future of Income Bonds

Description: Why has the once fallen star of income bonds started to rise after spending over seventy years below the financial horizon? Is it because income bonds provide many of the advantages of debt financing with the non-fixed payments feature of equity financing? Could it be caused by the high yields they carry considering the risk involved? Is it the result of the large tax savings created in many cases? All of these questions are important. Eighteen years ago income bonds were one of the least respected and most disliked types of securities that a company could issue. Today they have a limited but growing use and an ever increasing acceptance. This study is an attempt to determine and give reasons for the development and use of income bonds in the past, present, and future. It traces the development of income bonds, explains the advantages and disadvantages associated with them, and prognosticates about their future.

Relationship of metal surfaces to heat-aging properties of adhesive bonds

Description: A study of the probable causes of deterioration of each of several adhesives in bonds to stainless steel at temperatures from 400 degrees to 550 degrees Fahrenheit. Preliminary studies of aluminum surfaces on which ions of metal used in stainless steel were introduced showed that iron was probably catalyzing a thermal deterioration of the adhesive. Results regarding the studies of adhesive bonds to aluminum surfaces and studies of adhesive bonds to stainless-steel surfaces are provided.
