Zimmer, Zachary | Living arrangements and socio-demographic conditions of older adults in Cambodia | Since the takeover of Cambodia by the Khmer Rouge in 1975, analysis of social conditions in the country has been lacking. Only recently has dependable socio-demographic data become available. We use some of these data to examine living arrangements and other socio-demographic conditions among Cambod... | Living arrangements; Older adults; Socio-demographic conditions; Coresident children | 2002 |

Harpending, Henry C. | Paternal age and genetic load | The incidence of base substitutions in humans increases with the age of the father, which shows up as an increased incidence of mutational disorders in the children of older fathers. There is a less obvious implication: an extended period of high average paternal age in a population will lead to inc... | | 2013-01-01 |

Broughton, John | Pristine benchmarks and indigenous conservation? Implications from California zooarchaeology | The superabundance of tame wildlife during the early historic period in California astonished European explorers. And the historic accounts of incredible animal densities, most notably artiodactyls, have influenced a long-held perception that California Indians lived in harmony with nature. However,... | | 2004-01-01 |

Forster, Richard R. | Prevalence of pure versus mixed snow cover pixels across spatial resolutions in alpine environments | Remote sensing of snow-covered area (SCA) can be binary (indicating the presence/absence of snow cover at each pixel) or fractional (indicating the fraction of each pixel covered by snow). Fractional SCA mapping provides more information than binary SCA, but is more difficult to implement and may no... | | 2014-01-01 |

Nicoll, Kathleen | The climate and environment of Byzantine Anatolia: Integrating science, history, and archaeology | This article, which is part of a larger project, examines cases in which high-resolution archaeological, textual, and environmental data can be integrated with longer-term, low-resolution data to afford greater precision in identifying some of the causal relationships underlying societal change. | | 2014-01-01 |

Li, Minqi | Chinas grain production: a decade of consecutive growth or stagnation? | Some progressive writers have argued that while China's agricultural privatization achieved short-term gains, it did so by undermining longterm production facilities such as the infrastructure and public services built in the socialist era.1 Environmental scholars have questioned the sustainability ... | | 2014-01-01 |

Hall, Thad | Who asks for voter identification? Explaining poll-worker discretion | As street-level bureaucrats, poll workers bear the primary responsibility for implementing voter identification requirements. Voter identification requirements are not implemented equally across groups of voters, and poll workers exercise substantial discretion in how they apply election law. In sta... | | 2014-01-01 |

Utz, Rebecca L. | Walking the dog: the effect of pet ownership on human health and health behaviors | This analysis explores whether pet owners have better physical health outcomes, and if so, whether the positive physical health benefits are explained by better health behaviors that result from having to take care of the pet's physical needs. Data come from the National Health and Nutrition Examina... | | 2014-01-01 |

Drews, Frank | Does the shoe fit? Applying lessons learned in aviation to healthcare | Aviation's successful use of Decision Support Systems (DSS) has not been replicated in the healthcare subset of DSS referenced as Clinical Decision Support (CDS).

Korinek, Kim | The effect of household and community on school attrition: an analysis of Thai youth | We analyze school attrition among youth in Kanchanaburi province, Thailand. We find that family investments in schooling are shaped by both household and local community contexts. There is an enrollment advantage for girls across different households and communities. We find that youth whose mothers... | | 2012-01-01 |

Codding, Brian F. | Socioecological dynamics structuring the spread of farming in the North American Basin-Plateau Region | The spread of agriculture is a major driver of social and environmental change throughout 25 the Holocene, yet experimental and ethnographic data indicate that farming is less profitable than foraging, so why would individuals choose to adopt agriculture leading to its expansion?

Zimmer, Zachary | Education of adult children and mortality of their elderly parents in Taiwan | Research shows an older adult's education is strongly associated with mortality. But in societies such as Taiwan, where families are highly integrated, the education of family members may be linked to survival. Such may be the case in settings where there are large gaps in levels of education acros... | Education; Mortality | 2005 |

Kowaleski-Jones, Lori | Exploring the influence of the National School Lunch Program on children using the early childhood longitudinal study | Using data from the Early Childhood Longitudinal Study, 1998-1999 Kindergarten Cohort, the proposed study examines two research questions. First, what are the effects of participation in the National School Lunch Program (NSLP) on changes in children's behavior, test scores, and body weight?

Wolfinger, Nicholas H. | Thanks for nothing: income and labor force participation for never-married mothers since 1982 | We examine the changing social and economic characteristics of women who give birth out of wedlock. Using Current Population Survey data collected between 1982 and 2002, we find that never-married mothers remain impoverished. Their income growth over these years was modest despite substantial gains ... | | 2011 |

Waitzman, Norman J. | Half-life of cost-of-illness estimates: the case of Spina Bifida | Neural tube defects, which include spina bifida, are one of the most frequent and important categories of birth defects. Accordingly, there has been considerable interest in studying the impact of spina bifida as a public health problem. This impact can be measured in various ways, including dise... | Spinal cord; Birth defect; Healthcare costs | 2004-10-12 |

McDaniel, Susan | Emotional support and family contacts of older Canadians | Elderly people can no longer expect to spend their senior years living with their families. This is particularly true for older women, who as widows are more and more likely to be living alone. With more seniors living on their own, emotional support from family may not be as easy to come by as i... | | 1993 |

Broughton, John | Terminal Pleistocene fish remains from Homestead Cave, Utah, and implications for fish biogeography in the Bonneville Basin | Eleven fish species were identified from Homestead Cave, Utah. The remains, concentrated in the lowest stratum of the deposit, were accumulated by owls between approximately 11,200 and 10,100 14C yr B.P. and likely represent fish associated with the final die-off of the Lake Bonneville fauna.

Rogers, Alan R.; Jorde, Lynn B. | Genetic evidence on modern human origins | A review of genetic evidence leads to the following conclusions concerning human population history: (1) Between 33,000 and 150,000 years ago the human population expanded from an initial size of perhaps 10,000 breeding individuals, reaching a size of at least 300,000. (2) Although the initial popu... | Population history; Mitochondrial DNA; Mismatch distribution; Intermatch distribution; Replacement hypothesis; Population bottlenecks | 1995 |
