This study posited that maturational growth in emotion regulation should be associated with reduction in hyperactivity during the transition into adolescence. The longitudinal design assessed emotion regulation and hyperactivity in an urban community sample of children in three waves, at ages 10.6, 11.6, and 12.6 years. A parallel growth curve...
The prevalence of sexual violence among the college student population has become a significant public health issue. The real magnitude of the problem is unknown since most students do not report incidents of sexual violence. However, some studies have estimated that 1 in 5 students experience sexual violence while in...
This study contributes to our understanding of positive adult development by examining resilience processes in adulthood. Resilience is often considered to be an individual-level trait. However, the child development literature has consistently shown that support from parents and caring others is a critical component of resilience. Less is known about...
Health care providers, including complementary and alternative medical (CAM) practitioners, exert a significant influence on parental pediatric vaccination decisions. Use of CAM therapies is increasing in Oregon. Concomitantly, there has been a decade-long increase in parental vaccine refusal in Oregon, rising from 1 to 5 percent from 2000-2009. For example,...
In Zambia, there are approximately 920,000 people living with HIV/AIDS. Children are often referred to as a "window of hope" due to a low HIV/AIDS prevalence rate (UNAIDS/WHO, 2006). With growing numbers of infections and an increased strain on the social and economic structure due to HIV/AIDS there is a...
In the ever-evolving field of computer science (CS) education, the significance of teachers and their backgrounds have often been overshadowed by the predominant focus on students. Teachers in the K-12 often lack the necessary expertise and have limited support provided by existing CS-based curricula. While research on CS education effectiveness...
We have developed a framework for Web-based GIS/database applications which allow users to insert, update, delete, and query data with a map interface displayed by Web browsers. The framework was designed so that a Web-based GIS application that uses ArcIMS as a map server can be easily created, customized, and...
In this report, I first introduce three areas of interest to collaborative filtering researchers, namely: (a) how to solve the sparsity and scalability problems in recommendation systems; (b) how to rapidly develop and test collaborative filtering algorithms; and (c) how to apply collaborative filtering to unbounded numeric preference data. In...
"Collaborative filtering algorithms’ performances have been evaluated using a variety of metrics.
These metrics, such as Mean Absolute Error and Precision, have often ignored recommendations for
which they do not have data. Ignoring these recommendations has provided numbers which do not
accurately represent the user experience. Qualitatively we have seen...
Application Programming Interfaces (APIs) enable software developers to utilize and create functionality that would otherwise take a lot of time and effort to build from scratch. Consequently, an essential part of software engineering training is for students to learn how to use APIs effectively. The existing jTutors system enables an...
