We show the existence of families of elliptic curves over Q whose generic rank is at least 2 for the torsion groups Z/8Z and Z/2Z× Z/6Z. Also in both cases we prove the existence of infinitely many elliptic curves, which are parameterized by the points of an elliptic curve with positive rank, with such torsion group and rank at least 3. These results represent an improvement of previous results...

We show that U.S. manufacturing wages during the Great Depression were importantly determined by forces on firms' intensive margins. Short-run changes in work intensity and the longer-term influence of potential productivity combined to influence real wage growth. By contrast, the external effects of unemployment and replacement rates had much less impact. Empirical work is undertaken against t...

Analysis of differences in the recognized and realized costs of stock options and the implications for studies of tax avoidance. ii This thesis is dedicated to my parents, Jeff and Anne Campbell. Without their love, endless support, and encouragement throughout my life this work would not be possible. I also lovingly dedicate this thesis to my husband, Ryan Austin, for the encouragement he gave...

Even risky pension sponsors could offer essentially riskless pension promises by contributing a sufficient level of resources to their pension trust funds and by investing those resources in fixed-income securities designed to deliver their payoffs just as pension obligations are coming due. However, almost no firm has chosen to fund its plan in this manner. We study the optimal funding choice ...

In the early 70’s, D.M. Campbell published three papers on majorizationsubordination results for locally univalent functions. In particular, he showed that if F is linearly invariant of order α and if f is subordinate to F on {z : |z| < 1}, then f ′ is majorized by F ′ on {z : |z| < m(α)} where m(α) = α+ 1− √ α2 + 2α, provided α ≥ 1.65. He conjectured, in fact, that this result also held for 1....

It will liardly have surprised our readers to learn that the Lieutenant-Governor of Bengal has, on the earliest opportunity, substituted a civilian for a medical officer as superintendent of jails, Mr. Campbell, as is generally believed, entertaining no exaggerated notions regarding the value of the medical profession; however, it is useless to cry over spoilt milk, and on the present occasion ...

Campbell (1960) proposed the theory that creativity required blind variation and selective retention (BVSR). More than a half century has transpired without any resolution of the controversy over the theory’s validity. This inability to reach consensus may reflect a fundamental failure on both sides to define the critical terms of the debate, namely, creativity and blindness. Hence, to help res...
