Reproductive Decision-Making In Transitional Contexts, Kristin Snopkowski
Reproductive Decision-Making In Transitional Contexts, Kristin Snopkowski
Kristin Snopkowski
Over the past two hundred years, most societies around the world have experienced fertility transitions, defined as a dramatic decline in reproductive rates through time. The conscious decision to reduce fertility to very low levels appears maladaptive and poses a theoretical challenge to human behavioral ecologists who expect humans to maximize long term fitness. I develop a theoretical model to explain currently low fertility rates that incorporates both cultural and economic hypotheses of fertility decline and test these using data from San Borja, Bolivia, a society currently undergoing a fertility transition. Results show that both economic and cultural information are …
A Test Of The Intergenerational Conflict Model In Indonesia Shows No Evidence Of Earlier Menopause In Female-Dispersing Groups, Kristin Snopkowski, Cristina Moya, Rebecca Sear
A Test Of The Intergenerational Conflict Model In Indonesia Shows No Evidence Of Earlier Menopause In Female-Dispersing Groups, Kristin Snopkowski, Cristina Moya, Rebecca Sear
Kristin Snopkowski
Menopause remains an evolutionary puzzle, as humans are unique among primates in having a long post-fertile lifespan. One model proposes that intergenerational conflict in patrilocal populations favours female reproductive cessation. This model predicts that women should experience menopause earlier in groups with an evolutionary history of patrilocality compared with matrilocal groups. Using data from the Indonesia Family Life Survey, we test this model at multiple timescales: deep historical time, comparing age at menopause in ancestrally patrilocal Chinese Indonesians with ancestrally matrilocal Austronesian Indonesians; more recent historical time, comparing age at menopause in ethnic groups with differing postmarital residence within Indonesia …
A Synthetic Biosocial Model Of Fertility Transition: Testing The Relative Contribution Of Embodied Capital Theory, Changing Cultural Norms, And Women's Labor Force Participation, Kristin Snopkowski, Hillard Kaplan
A Synthetic Biosocial Model Of Fertility Transition: Testing The Relative Contribution Of Embodied Capital Theory, Changing Cultural Norms, And Women's Labor Force Participation, Kristin Snopkowski, Hillard Kaplan
Kristin Snopkowski
This article presents a biosocial model of fertility decline, which integrates ecological-economic and informational-cultural hypotheses of fertility transition in a unified theoretical framework. The model is then applied to empirical data collected among 500 women from San Borja, Bolivia, a population undergoing fertility transition. Using a combination of event history analysis, multiple regression, and structural equation modeling, we examine the pathways by which education responds to birth cohort, parental education and network ties, and how age at first birth and total fertility, in turn, respond to birth cohort, social network ties, education, expectations about parental investment, work, and contraceptive use. …
Father Absence And Reproduction-Related Outcomes In Malaysia, A Transitional Fertility Population, Paula Sheppard, Kristin Snopkowski, Rebecca Sear
Father Absence And Reproduction-Related Outcomes In Malaysia, A Transitional Fertility Population, Paula Sheppard, Kristin Snopkowski, Rebecca Sear
Kristin Snopkowski
Father absence is consistently associated with children’s reproductive outcomes in industrialized countries. It has been suggested that father absence acts as a cue to particular environmental conditions that influence life history strategies. Much less is known, however, about the effects of father absence on such outcomes in lower-income countries. Using data from the 1988 Malaysian Family Life Survey (n=567), we tested the effect of father absence on daughters’ age at menarche, first marriage, and first birth; parity progression rates; and desired completed family size in Malaysia, a country undergoing an economic and fertility transition. Father absence during later …
Ethnoarchaeology As A Strategy For Building Frames Of Reference For Research Problems, Pei-Lin Yu
Ethnoarchaeology As A Strategy For Building Frames Of Reference For Research Problems, Pei-Lin Yu
Pei-Lin Yu
Ethnoarchaeology is a powerful strategy for structuring archaeological research questions that uses ethnographic information to make inferences about the material residues of past human activities. Ethnoarchaeology is not a theoretical approach per se, so it can investigate research questions generated from a wide variety of theoretical perspectives. Ethnoarchaeological scopes and scales of research are expanding rapidly in geography, chronology, method, and theoretical stance, from variables conditioning the manufacture of traditional technology to the evolution of symbolic expression and ritual behaviors.
Ice Patch Archaeology And Paleoecology In Glacier National Park, Pei-Lin Yu
Ice Patch Archaeology And Paleoecology In Glacier National Park, Pei-Lin Yu
Pei-Lin Yu
A fragment of basket. The tip of a digging stick. The shaft of an ancient spearthrower. Very rarely do such items preserve in the archeological record, but these works of ingenuity and craftsmanship, reflective of past human presence and lifeways in sub-alpine and alpine environments, have been preserved in nearly perfect condition in ice and snow patches for hundreds—or even thousands—of years. Also locked in the ice are traces of vanished ecosystems: animal scat, bones, horns, antlers, fragments of ancient wood, even entire “frozen forests.”
Implications Of Upper Columbia River Lithic Technology For Prehistoric Fishing In The Rockies, Pei-Lin Yu, Jackie M. Cook
Implications Of Upper Columbia River Lithic Technology For Prehistoric Fishing In The Rockies, Pei-Lin Yu, Jackie M. Cook
Pei-Lin Yu
Lithic tools used for fish processing in North America range from hafted lanceolate bifaces and microlithic blades to handheld lunate tools. Despite use wear and residue analysis, archaeologists still lack diagnostic means to identify archaeological fish processing tools at larger scales, resulting in a dearth of knowledge about past fishing behavior. This paper describes and predicts variability in tool shape using ethnographic fish processing data and functional morphology of tabular quartzite tools from Kettle Falls, a major Columbia River salmon fishery. Gender-specific organization of labor during intensive fish harvest and technological behavior associated with large-scale processing practiced by aquatic-focused foragers …

Grappling With Climate Change: Impacts To Heritage Resources, Lauren Meyer, Pei-Lin Yu, Randall Skeirik, Virginia Salazar-Halfmoon

17th century adobe walls collapsing at Tumacácori; historic inscriptions rapidly eroding at El Morro; ancestral pueblo field houses at Bandelier impacted by significant soil erosion. Is this deterioration and loss the result of a lack of proper maintenance, a misunderstanding of the needs of fragile site materials, the cumulative effects of 'normal' deterioration, or the result of random and unpredictable natural events and material failures? Could any (or all) of it be related to climate change? As a cultural resource manager, climate change is a difficult matter to grapple with. Can one comfortably say that a wall collapse is the …
Pit Cooking And Intensification Of Subsistence In The American Southwest And Pacific Northwest, Pei-Lin Yu
Pit Cooking And Intensification Of Subsistence In The American Southwest And Pacific Northwest, Pei-Lin Yu
Pei-Lin Yu
Pit cooking leaves durable, measurable remains and is relevant to the study of resource intensification. This thesis examines pit cooking as a means to explore and quantify the initial conditions for two different modes of intensification: incipient Southwestern food production and semi-sedentized foraging in the inland Pacific Northwest.
First, analytical tools for variability in pit ovens, and a model statement about the role of pit cooking in intensification, were drawn from an ethnographic frame of reference governing pit oven function, physical variation, and contexts of use. Using those tools, hypothetical statements were developed for the relationship between pit oven cooking, …
