201 Rogers, Alan R.Model of kin-structured migrationWhen individuals disperse from one local group to another, they often do so in the company of relatives. This is known as "kin-structured migration," and its effect on genetic population structure is investigated here. It is shown that when migration is kin-structured, the ratio of between- to with...Fission; Mobility; Population1987
202 O'Rourke, Dennis H.Spatial and temporal stability of mtDNA haplogroup frequencies in native North AmericaMitochondrial DNA lineage frequencies in prehistoric Aleut, eastern Utah Fremont, Southwestern Anasazi, Pyramid Lake, and Stillwater Marsh skeletal samples from northwest Nevada and the Oneota of western Illinois are compared with those in 41 contemporary aboriginal populations of North America.

203 Fogel, Alan DaleMaternal speech to three-month-old infants in the United States and JapanAn American-Japanese comparison of maternal speech to 3-month-old infants is presented. Mother-infant dyads were videotaped in the laboratory, and the maternal speech was analysed by function and syntactic form. US mothers were more information-oriented than were Japanese mothers; they also used mor...Maternal speech; Information-oriented; Affect-oriented; Prelinguistic infants; Baby talk1990
204 O'Rourke, Dennis H.Biochemical heterozygosity and morphologic variation in a colony of papio hamadryas hamadryas baboonsThis 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; Inbreeding1994
205 Wolfinger, Nicholas H.Problems in the pipeline: gender, marriage, and fertility in the ivory towerWomen have traditionally fared worse than men in the workplace. In few places has this been more apparent than higher education (Jacobs, 1996). In 2003, women received 47% of PhDs awarded (National Center for Education Statistics [NCES], 2005a) but comprised only 35% of tenured or tenure-track fac...Family; Career; Marital Status2008
206 Smith, Ken R.; Waitzman, Norman J.Double jeopardy: interaction effects of marital and poverty status on the risk of mortalityThe 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 Survey1994
207 Malloy, Thomas E.; Jensen, Gary C.Utah Virtual Lab: JAVA interactivity for teaching science and statistics onlineThe Utah on-line Virtual Lab is a JAVA program run dynamically off a database.

208 Zimmer, ZacharyDistinguishing the spending preferences of seniorsOne thousand, four hundred and six seniors were asked about their consumer spending preferences. While some could name a product spending preference, others could not. This study examines the characteristics that best distinguish those elders who are uninterested in spending on consumer products fro...Spending preferences; Seniors1996
209 Rogers, Alan R.Quantitative genetics of sexual dimorphism in human body sizeA classical data set is used to predict the effect of selection on sexual dimorphism and on the population means of three characters--stature, span, and cubit--in humans. Given selection of equal intensity, the population means of stature and of cubit should respond more than 60 times as fast as d...Societies; Selection; Species1992
210 McDaniel, SusanSocial bases of neonatal and postneonatal mortality: an ecological analysis of Alberta, CanadaCanada's steady downward trend in mortality in the twentieth century has not been matched by a similar decline in infant mortality. This paper examines, by reference to census divisions in Alberta, the degree to which neonatal and postneonatal mortality are related to environmental factors. Although...Death; Exogeneous; Rates1981

212 Smith, Ken R.; Mineau, Geraldine Page; Kerber, Richard A.Effects of childhood and middle-adulthood family conditions on later-life mortality: evidence from the Utah population database, 1850-2002How do parents affect the health and longevity of their children? Parents can affect their children's life chances by transmitting a genetic endowment (or liability) for a long life while also providing resources and an environment that enhances (or limits) their children's longevity. Recently, m...Growth; Death; Adolescence; Geriatrics2005-01-05
213 Smith, Ken R.Association of physical and behavioral characteristics with menstrual cycle patterns in women age 29-31 yearsWe examined the association between menstrual cycle characteristics(cycle length, variability, and bleeding length) and physical and behavioral attributes in 766 women age 29-31 years. Menstrual cycled at a were prospectively recorded as part of the Menstruation and Reproductive History Study of col...1996
214 Zick, Cathleen D.; Brown, Barbara B.; Kowaleski-Jones, Lori; Smith, Ken R.Household food expenditure patterns: a cluster analysisThe 2001 report titled "The Surgeon General's Call to Action to Prevent and Decrease Overweight and Obesity" identified overweight and obesity as major public health problems, costing U.S. society as much as $117 billion a year and posing as great a threat of death as poverty, smoking, or problem ...Food expenditure; Buying habits; Buying patterns2007
215 Yu, ZhouHeterogeneity in Asian American homeownership: the impact of household endowments and immigrant statusRecently, research has begun to investigate the reasons for differences in homeownership rates between Asian and whites. This paper extends this research by examining the heterogeneity that exists across Asian groups in the United States. We find that there are important differences across geog...Immigrants; Homeownership2003
216 Caserta, Michael; Lund, Dale A.Toward the development of an inventory of daily widowed life (IDWL): guided by the duel process model of coping with bereavementThe Dual Process Model of Coping with Bereavement (Stroebe & Schut, 1999) suggests that the most effective adaptation involves oscillaton between two coping processes: loss-orientation (LO) and restoration-orientation (RO). A 22-item Inventory of Daily Widowed Life (IDWL) was developed to measure t...Bereavement; Grief reaction; Widowhood; Psychological orientation; Adaptation, Psychological2007-07
217 Smith, Ken R.; Zick, Cathleen D.;Brown, Barbara B.; Fan, Jessie Xiaojing; Kowaleski-Jones, LoriPhysical activity during the transition from adolescence to adulthoodWe examine how age, life course roles, and contextual variables relate to both the composition and the overall level of physical activity in late adolescence and early adulthood. Methods: Data on respondents age 15 to 29 y in the 2003 American Time Use Survey are used to estimate multivariate logis...Time use; Active leisure; Team sports; Active transportation; Life course2007
218 Wolfinger, Nicholas H.Thanks for nothing: changes in income and labor force participation for never-married mothers since 1982This study examines whether the changing social and economic characteristics of women who give birth out of wedlock have led to higher family incomes. Using Current Population Survey data collected between 1982 and 2002, we find that never-married mothers remain poor. They have made modest econom...Motherhood; Single Mothers; Income; Population surveys2006-07-26
219 Hawkes, KristenSome current ideas about the evolution of the human life historyHuman life history is characterised by a long juvenile period (weaning to reproductive maturity), and a long post-reproductive lifespan in females. How do we explain the differences between our nearest relatives, the great apes, and ourselves? This chapter summarises some recent attempts to use l...Human life history; Fertility; Apes; Juvenile period1999
220 Korinek, KimFamily relations and the experience of loneliness among older adults in Eastern EuropeIn this paper I conceptualize and analyze the determinants of loneliness among older adults in Russia and Bulgaria, two former communist societies experiencing myriad and challenging transitions - economically, demographically, and socially.
