The Anatomy of a Spin-Off
Section 355 of the Internal Revenue Code, which specially treats certain forms of corporate reorganization, has been the constant subject of both scholarly commentary and litigation. The experience of functioning under these spin-off provisions has resulted in clarification of the law and has also raised significant questions as to its scope. The precise limits of the section remain to some extent in a state of flux and await further exposition by the courts
The mechanism of stress-corrosion cracking in 7075 aluminum alloy
Various aspects of stress-corrosion cracking in 7075 aluminum alloy are discussed. A model is proposed in which the continuous anodic path along which the metal is preferentially attacked consists of two phases which alternate as anodes
What is Theology to a Black Seminarian
This article was originally published in The Prophet -- a journal created by and for the students at the Boston University School of Theology (BUSTH) to amplify the voices of STH students by promoting and sharing a range of perspectives on matters of concern including, but not limited to, spiritual practices, faith communities and society, the nature of theology, and current affairs. It serves as a platform for STH students to share their academic work, theological reflections, and life experiences with one another and the wider community.This reflection is part of a collection of responses to the theme: "What is Theology?"
Treatment increases stress-corrosion resistance of aluminum alloys
Overaging during heat treatment of the aluminum alloys immediately followed by moderate plastic deformation, preferably by shock loading achieves near optimum values of both yield strength and resistance to stress corrosion. Similar results may be obtained by substituting a conventional deformation process for the shock loading step
Trends in wages, underemployment, and mobility among part-time workers
This study examines three trends in the labor market experiences of part-time workers: (1) trends in real earnings; (2) trends in the extent of involuntary part-time work (underemployment); and (3) trends in the rate of exit from part-time work. Data are from Current Populating Surveys from the 1970s and 1980s. It considers whether observed changes in the position of part-time workers are due to changes in the attributes of part-time workers, the occupational and industrial location of part-time jobs, the process of selectivity into part-time employment, or changes in the returns to these factors. The questions addressed in this study have significant implications for research on poverty because, unless supplemented by other family earners, the low earnings levels of part-time job holders make them vulnerable to poverty and dependency.
An approximate Riemann solver for hypervelocity flows
We describe an approximate Riemann solver for the computation of hypervelocity flows in which there are strong shocks and viscous interactions. The scheme has three stages, the first of which computes the intermediate states assuming isentropic waves. A second stage, based on the strong shock relations, may then be invoked if the pressure jump across either wave is large. The third stage interpolates the interface state from the two initial states and the intermediate states. The solver is used as part of a finite-volume code and is demonstrated on two test cases. The first is a high Mach number flow over a sphere while the second is a flow over a slender cone with an adiabatic boundary layer. In both cases the solver performs well
