How Extrinsic Mortality Affects Age At Menarche And Fertility In A 1970 British Cohort, Kimberly Marie Neagle
How Extrinsic Mortality Affects Age At Menarche And Fertility In A 1970 British Cohort, Kimberly Marie Neagle
Boise State University Theses and Dissertations
Extrinsic mortality is the likelihood of mortality that is not conditional on reproductive effort. It does not depend on a person’s behavior and cannot be changed by altering behavior. Theoretically, extrinsic mortality plays a major role in the evolution of life history and the variation in reproductive strategies. Using life history theory as a framework, with higher extrinsic mortality cues women should speed up reproduction to maximize fitness in uncertain or risky environments, and in environments with little risk, women can allocate their energy to somatic development and in this time, accrue resources such as education and career opportunities. Thus, …
Effects Of Intention Status And Social Support On Parental Investment, Kayla Downs
Effects Of Intention Status And Social Support On Parental Investment, Kayla Downs
Boise State University Theses and Dissertations
According to life history theory, human mothers rely on assistance from others for childrearing help. Studies have shown that mothers who have insufficient support often report having unwanted or mistimed pregnancies. In turn, unwanted pregnancies may lead to reduced parental investment. This study is the first to analyze the interaction between pregnancy intention status and social support to better understand parental investment. Using data from the Millennium Cohort Study of the U.K. which includes over 18,000 respondents, this study examines how planned pregnancy and social support variables – measured as assistance from a partner, family, or friends – is associated …
Variation In The Configuration Of The Middle Snake River And Its Relationship To Prehistoric Fishing Site Locations, Joseph Wardle
Variation In The Configuration Of The Middle Snake River And Its Relationship To Prehistoric Fishing Site Locations, Joseph Wardle
Boise State University Theses and Dissertations
The configuration of the various elements of a river system can have significant impacts on the availability, abundance, and nutritional profitability of aquatic organisms utilized as food by groups of human foragers. These factors may have influenced the location and timing of prehistoric fishing along the Middle Snake River in southern Idaho during the Late Archaic when use of fish as a resource increased (beginning approximately 1500 B.P.). Previous work has established a relationship between physiographic features of the Middle Snake River channel and the presence of fishing sites. To improve on future studies of this type, it is important …
