DISSERTATION RESEARCH: "Phenotypic Resolution of Parent-Offspring Conflict among the Karo of North Sumatra, Indonesia

0003951行为生态学的Smith/ KushnickTheorists假设个体的遗传适应性可以通过不同的策略来改变。 这篇论文的研究项目由一个文化人类学家从华盛顿大学将测试假设父母的投资理论与数据的母亲和孩子的互动，从印尼苏门答腊岛的农村社会。 该项目将通过对每个村庄200名母亲的深入访谈，记录两个样本母亲的生育间隔和母乳喂养行为的数据，一个样本来自相对富裕的村庄，另一个样本来自相对不那么富裕的村庄。数据还将来自对婴儿行为、母乳喂养和其他通过扫描采样进行的互动的行为观察。这些数据将使学生能够测试从理论中得出的预测，例如假设贫困的母亲社会经济环境将有利于长间隔;良好的母亲社会经济条件将有利于要求较低的后代和较不细心的父母。该项目的数据将允许通过假设检验进行广泛的理论发展，这将促进我们对人类养育行为的理解。 此外，该项目将增进我们对世界这一重要地区的了解，并有助于培训一名年轻的社会科学家。

0003951Smith / KushnickTheorists in behavioral ecology assume that the genetic fitness of an individual can be changed by different strategies. This dissertation research project by a cultural anthropologist from the University of Washington will test hypotheses about parental investment theory with data on mother-child interactions from a rural society in Sumatra, Indonesia. The project will record data on interbirth intervals and breastfeeding behavior of two samples of mothers, one from a relatively well-off and one from a relatively less well off village, through an intensive interview with 200 mothers in each village. Data will also come from behavioral observations of infant behavior, breastfeeding and other interactions done through scan sampling. This data will allow the student to test predictions drawn from theory such as the hypothesis that poor maternal socioeconomic contexts will favor long interbirth intervals; that good maternal socioeconomic conditions will favor less demanding offspring and less attentive parents. The data from this project will allow extensive theory development through hypothesis testing, which should advance our understanding of human parenting behavior. In addition the project will advance our knowledge about this important region of the world and contribute to the training of a young social scientist.
