There has been little prior research reporting strategy usage in end-user problem solving, and even less using gender as a factor. Without this type of information, enduser programming systems cannot know the “target” at which to aim, if they are to support male and female end-user programmers’ debugging. As a...
Programming parallel machines has been a difficult and unrewarding task. The short lifespan of parallel machines and their incompatibility have made it difficult to utilize them. Our goal here is to create an environment for parallel computing which allows users to take advantage of parallel computers without writing parallel programs....
End users' programs are fraught with errors, costing companies millions of dollars. One reason may be that researchers and tool designers have not yet focused on end-user debugging strategies. To investigate this possibility, this dissertation presents eight empirical studies and a new strategy-based end-user debugging tool for Excel, called StratCel....
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...
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...
While there are many ways to evaluate a user interface design, the user's mental workload and situation awareness (SA) are particularly important considerations in the supervisory control of safety-critical systems. Typically, operators of these systems must monitor high-volume, time-sensitive status information. Interface design for this domain can be challenging and...
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...
"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...
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...
The major purpose of this study was to determine if there were differences between well-trained pre- adolesents and untrained, but normally active counterparts in physical working capacity , body composition and blood lipids. The study hypotheses were that the trained subjects would have a lower mean body fat percentage, lower...
This study compared the perceptions of health education experts, principals and teachers regarding the ranking in order of importance of organizing school health programs within the elementary schools under the Jurisdiction of Bangkok Metropolis, Thailand. Of 604 subjects participating, 19 were health education experts from universities, Ministry of Public Health...
The purpose of this study was to compare the effectiveness of
teaching high school health by team teaching and traditional teaching
methods. For this study 114 second-semester sophomore health
students from Centennial High School in Gresham, Oregon were
used, distributed in three health classes as a control group, utilizing
traditional...
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,...
Sexual assault is a major public health concern in the U.S, and college students are particularly vulnerable to victimization. A health issue that affects nearly one in four women (Fisher, Cullen, & Turner, 2000; Karjane, Cullen, & Turner, 2005) and that is associated with severe negative health outcomes, including depression...
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...
The design of programming tools is slow and costly. To ease this process, we have developed a design pattern catalog aimed at providing guidance about how to design tools for developers. This guidance is grounded in Information Foraging Theory (IFT), which empirical studies have shown to be useful for understanding...
Healthcare discrimination is associated with various health-related attitudes, behaviors, intentions, and outcomes including provider avoidance, underutilization or increased use of healthcare services, use of alternative means of healthcare, delays in medical care, less satisfaction with care, poor health behaviors, and poorer health outcomes. Since 2001, Muslims and Arabs in the...
Low-Income urban African American (LIU-AA) youth are at high risk for HIV/STIs and adolescent pregnancy. Sexual health websites (SHWs) offer an inexpensive, easy-to-disseminate, and potentially highly-accessible method of improving sexual health knowledge, awareness, and help-seeking. The present study examined engagement regarding sexual health websites for at-risk, LIU-AA youth. We conducted...

Background. The prevalence of pediatric dental caries (PDC) is 55.7% nationally, 52% in Oregon, and 73% in Southeastern Oregon. We examined prevention programs, clinical services, and water fluoride levels in Southeastern Oregon to understand the high PDC prevalence.
Methods. We conducted telephone surveys and used secondary data to assess water...

In the U.S., the number of people waiting for an organ donation is increasing exponentially while the number of registered donors is slowly rising. This discrepancy leads to a great number of people dying while waiting for an organ donor. The opt-in system, lack of education around donation, and having...
