O'Rourke, Dennis H. | Biochemical heterozygosity and morphologic variation in a colony of papio hamadryas hamadryas baboons | This analysis examines the association between genetic heterozygosity and individual morphologic variation in a captive population of Papio hamadryas hamadryas consisting of 403 juveniles and adults. The population structure of the colony was artificially generated and maintained and is thus rigoro... | Population genetics; Polygenic; Inbreeding | 1994 |

Friedrich, Frances | Capacity demands of automatic processes in semantic priming | In three experiments, we examined the effects of prime-target stimulus onset asynchrony (SSA) and the proportion of related primes and targets (relatedness proportion, or RP) on semantic priming when the prime was either named or was searched for a specific letter . In Experiment 1, with an RP of .... | Semantic priming; Stimulus onset asynchrony | 1994 |

Smith, Ken R.; Waitzman, Norman J. | Double jeopardy: interaction effects of marital and poverty status on the risk of mortality | The purpose of this paper is to examine the hypothesis that marital and poverty status interact in their effects on mortality risks beyond their main effects. This study examines the epidemiological bases for applying an additive rather than a multiplicative specification when testing for interacti... | National Health and Nutrition Examination Survey | 1994 |

Kukathas, Chandran | Explaining moral variety | Reflection on the variety of forms of social life has long been a source of moral skepticism. The thought that there are many radically different social systems, each of which colors the way its members think about moral and political questions, has been thought by many moral philosophers to underm... | Standards; Cultural; Criticism | 1994 |

Rogers, Alan R.; Jorde, Lynn B. | Founder effect: assessment of variation in genetic contributions among founders | We present a Monte Carlo method for determining the distribution of founders' genetic contributions to descendant cohorts. The simulation of genes through known pedigrees generates the probability distributions of contributed genes in recent cohorts of descendants, their means, and their variances. | | 1994 |

Rogers, Alan R.; Jorde, Lynn B. | Genetic structure of the Utah Mormons: comparison of results based on RFLPs, blood groups, migration matrices, isonymy, and pedigrees | The genetic structure of the Utah Mormon population is examined using 25 blood group and 47 RFLP alleles obtained from 442 subjects living in 8 geographic subdivisions. Nei's Gst was 0.013 (p < 0.002) for the RFLP data and 0.012 (p > 0.4) for the blood group data, showing that only 1% of the geneti... | | 1994 |

McDaniel, Susan | Health care in an aging Canada: constraint or choice? | It is often presumed that population aging will result in increased demand for health care, with older Canadians seen as a "burden" to the working population. Yet, such a presumption of direct correlation (with implied causality) belies the complex questions of societal choices in expenditures: fac... | Age factors; Canada; Health care costs | 1994 |

Rogers, Alan R. | Is migration kin structured? | We estimate the strength of kin-structured migration in six human populations (five from New Guinea and one from Finland) and in one population of nonhuman primates. We also test the hypothesis that migration is not kin structured by generating a sampling distribution of the estimator under the null... | | 1994 |

Rogers, Alan R.; Harpending, Henry C. | Mismatch distributions of mtDNA reveal recent human population expansions | Although many genetic studies of human evolution have tried to make distinctions between the replacement and the multiregional evolution hypotheses, current methods and data have not resolved the issue. However, new advances in nucleotide divergence theory can complement these investigations with a ... | | 1994 |

Berg, Cynthia A. | Role of problem interpretations in understanding the development of everyday problem solving | Imagine the following conversation between an 11-year-old and a 14-year-old. The two are fighting over how best to solve a problem that the 14-year-old experienced while working on a project at school. The problem involved completing the project so that it would be competitive for the class prize. T... | | 1994 |

Broughton, John | Size of the bursa of fabricius in relation to gonad size and age in laysan and black-footed albatrosses | Age determination can be difficult for birds that undergo little or no plumage change during life. This is the case for Laysan and Black-footed Albatrosses (Diomedea immutabilis and D. nigripes). The juvenile plumage for both these North Pacific albatrosses is completely grown by about five to six m... | Birds; Species; Development | 1994 |
