The microbial metabolism of benzene and crude oil under diverse anaerobic conditions.
(2000)
The research reported here expands the range of knowledge for anaerobic hydrocarbon metabolism, as well as provides a sound foundation for the microbial destruction of compounds once thought to be completely recalcitrant ...
The Sobolev approximation in a spherical shell expanding with constant radial velocity.
(2000)
A simple model of line radiative transfer in a circumstellar shell surrounding a supernova is presented. An examination of optical depth in an atmosphere with power-law expansion and a single source of opacity highlights ...

Perceptions of Cooperation in a Longitudinal Social Dilemma
(Small Group Research, 2000-10-01)
Most social dilemma studies of communication’s effects on cooperation are based on laboratory results with trivial incentives. Studies of real-life social dilemmas with nontrivial rewards are needed to extend the generality ...
A comparison of solutions of a Boussinesq system and the Benjamin-Bona-Mahony equation.
(2000)
We compare solutions of a regularized Boussinesq model system for water waves to solutions of the Benjamin-Bona-Mahony equation. Both the system and the equation are obtained as formal approximations to the Euler equations ...
The language of emotion in televised political advertising: Presidential spots, 1960--1996.
(2000)
Through computerized lexical analysis of 1,209 televised political commercials aired by the Democratic and Republican party's presidential nominees during general elections from 1960 to 1996, this study discerns which words ...
Building a Theory of Multi-Media CMC: An Analysis, Critique and Integration of Computer-Mediated Communication Theory and Research
(New Media & Society, 2000-12-01)
In order to provide directions for future computer-mediated communication (CMC) scholarship, in this article, I analyze, critique and integrate contemporary CMC theory and research. Particularly, based upon an analysis of ...
