A central challenge facing twenty-first century community-based researchers and prevention scientists is curriculum adaptation processes. While early prevention efforts sought to develop effective programs, taking programs to scale implies that they will be adapted, especially as programs are implemented with populations other than those with whom they were(More)
We have generated 362 bp and 547 bp partial sequences for Rana pipiens ephrin-A2 and ephrin-A5 mRNA, respectively. Translation homologies for the comparable segments of cDNA of chicken, mouse and human are 90.8, 86.9 and 84.4% for the ephrin-A2 sequence and 85.7, 85.0 and 85.0% for the ephrin-A5 sequence. Digoxigenin-labeled riboprobes were prepared and(More)

Acknowledgement I would like to thank my thesis advisor, Professor Frederick P. Brooks, Jr., for his full support of the ARM project. In 1976 he already had the idea to the use force-feedback ARM in the molecular docking problems. Dr. Mike Cory and Professor David Richardson were the pioneer users of the prototype system from the beginning. have given(More)
This study examined the applicability of extending the theory of planned behavior to explain the normative processes in substance use among Mexican-heritage youth. The theory identifies norms, attitudes, and perceived behavioral control as predictors of intentions, which in turn, predict behaviors. To date, the theory had a limited conceptualization of(More)
Involvement in creating antialcohol advertisements generates enthusiasm among adolescents; however, little is known about the messages adolescents develop for these activities. In this article, we present a content analysis of 72 print alcohol counteradvertisements created by high school (age 14-17 years old) and college (18-25 years old) students. The(More)
Utilizing part of the survey data collected for a National Institute on Drug Abuse (NIDA)-funded project from 29 public elementary schools in Phoenix, Arizona (N = 1,600), this study explored the underlying structure of Mexican-heritage youths' ethnic identity and cultural/linguistic orientation. Latent profile and transition analyses identified four(More)
Latent growth curve modeling was used to test four hypotheses. First, this study hypothesized that acculturation-related variables (e.g., Mexican-heritage youth's country of origin, time spent in the U.S., and language preference with family and friends) would be associated with initial levels of perceived discrimination. Guided by general strain theory(More)
Media literacy interventions offer promising avenues for the prevention of risky health behaviors among children and adolescents, but current literature remains largely equivocal about their efficacy. The primary objective of this study was to develop and test theoretically-grounded measures of audiences' degree of engagement with the content of media(More)
Media literacy intervention efficacy literature has focused on media-relevant (e.g., knowledge and realism) and behavior-relevant outcomes (e.g., attitudes and behaviors), without much attention paid to interpersonal communication outcomes. This project examined interpersonal communication after participation in two versions (analysis plus analysis and(More)
