As cities expand worldwide, understanding how species adapt to novel urban habitats will become increasingly important to conservation. The adrenocortical stress response enables vertebrates to cope with novel environmental challenges to homeostasis. We examined total and estimates of free baseline and stress-induced corticosterone (CORT) concentrations and CORT binding globulin (CBG) levels in...

In this article, we undertake an event-history analysis of fertility in Ghana. We exploit detailed life history calendar data to conduct a more refined and definitive analysis of the relationship among personal traits, urban residence, and fertility. Although urbanization is generally associated with lower fertility in developing countries, inferences in most studies have been hampered by a lac...

PURPOSE The purpose of this study was to explore factors that influence urban adolescent American Indian (AI) girls' sexual risk behavior. DESIGN A qualitative study was conducted with grounded theory methodology to reveal factors and processes that influence sexual risk behavior. METHOD Talking circles, individual interviews, and event history calendars were used with 20 urban AI 15- to 19...

Due to the inherent discrete nature of sensing, interpolation is a key activity in sensing. Interpolation in urban computing faces an unprecedented inference issue that was not present in large scale traditional sensing environments. Obstacles such as buildings and walls are prevalent in urban sensing, and it is important to consider them in urban sensing interpolation. This paper introduces an...

Micro-geographic data capturing the spatial distribution of economic activity within cities in history are difficult to access. This paper discusses how tall and durable buildings can be exploited as a source “big data” trace structure cities. To this end, we provide stylized evidence on building heights correlate with land values over space time cities, review related nascent literature, sugge...
