Gondolo, Paolo | Limits on R-parity violation from cosmic ray antiprotons | We constrain the hadronic R-parity violating couplings in extensions to the minimal supersymmetric standard model. These interactions violate baryon and lepton number, and allow the lightest superpartner (LSP) to decay into standard model particles. The observed flux of cosmic ray antiprotons plac... | R-parity; Supersymmetric models | 1998-06 |

Wiessner, Pauline W. | On emergency decisions, egalitarianism, and group selection | Boehm (CA 37:763-93) puts forward an important thesis-that with the evolution of egalitarian societies, privileged routes to reproductive advantage are blocked and the power of individua selection severely compromised. With competition so constrained, altruistic behavior can more readily spread i... | Boehm's mode; Evolution of altruistic behavior | 1998-06 |

Cashdan, Elizabeth A. | Why is testosterone associated with divorce in men? | There is evidence that in women high levels of testosterone are associated with more sexual partners and more permissive sexual attitudes. If a similar relationship holds true for men, the higher basal testosterone levels of divorced and unmarried men may be caused by this relationship rather than b... | Marriage; Separation; Hormones; Sexuality | 1998-06 |
