Urban African American adolescents exhibit high levels of risk behavior, disproportionately high rates of sexually transmitted infections (STIs), and are at risk for acquiring Human Immunodefiency Virus (HIV). To date, interventions that address the high rates of STIs in this population demonstrate only moderate efficacy. As researchers strive to develop...
Using a probability-based neighborhood sample of urban African American youth and a sample of their close friends (N = 202), we conducted a one-year longitudinal study to examine key questions regarding sexual and drug using norms. The results provide validation of social norms governing sexual behavior, condom use, and substance...
Northwest of Normal is the first part of a novel that takes place along an imaginary Oregon river called the Ipsyniho. The story grows from valley’s fertile loam like a blackberry vine, entangling a group of locals—fly fishing guides and midwives, artists and dope growers—just as a posse of wealthy...
The authors employ a social-ecological framework to aid our understanding of the complex array of factors in the immediate and broader environment that influence adolescent sexual development. Further, sexual development is viewed as normative and critical to positive growth. The authors provide an overview of the
Two-Cities Study, a multi-stage...
A method for measuring whole-tree interception of precipitation is presented which employs mechanical displacement sensors to measure trunk compression caused by the water captured by the tree. This direct and nondestructive method is demonstrated to be sensitive to less than 5 kg of interception field tests in Netherlands and Ghana.
Background: Wild food plants are a critical component in the subsistence system of rice farmers in Northeast Thailand. One of the important characteristics of wild plant foods among farming households is that the main collection locations are increasingly from anthropogenic ecosystems such as agricultural areas rather than pristine ecosystems. This...
The design of a projectile delivery system often plays a critical role in the durability and breakage patterns associated with spent projectile points. This paper presents the results of an experimental project designed to examine projectile point durability and breakage patterns between three different hafting methods. Specifically, we compare two...
This conceptual paper explores the nexus between travel and learning; an area of investigation long neglected by tourism researchers. Using Aristotle’s concepts of phronesis, techne and episteme a framework for the major areas of literature dealing with touristic learning are considered and opportunities and challenges for expanding the boundaries of...
