Examining directional decisions has proven easier in experiments with fish than in humans. With virtual reality, it is now easier to investigate directional decision-making behavior in humans. This remote virtual study examined directional decisions in 109 participants after watching virtual pedestrians, walking at different speeds and entering at different times,...
The purpose of this study is to name and give voice to the spiritual expression of leadership by women community college presidents. The following questions guided the research: (1) How do women community college presidents describe spirituality? (2) How does spirituality convey itself in the reflections, self-expression, and practice of...
How do organizational members socially construct the shared meaning of a mandated change in the external environment? The opportunity to address this question presented itself when President Barack Obama set forth a goal for American community colleges to increase the number of students completing certificates and degrees by 5 million...
As large-scale restorations of degraded rangelands are initiated, land managers need to
understand how decades of dominance by the invasive annual grass, cheatgrass (Bromus tectorum
L.), have altered ecosystem processes. One way to assess such alterations is by observing
differences in decay rates, since decomposition is determined by factors such...
Biodiversity loss is of global concern, and is due in part to deforestation and high consumer demand for wood and wood products. The neotropical tree species Cedrela odorata (“Spanish cedar” or “cedro”) is economically valuable for its wood and faces threats of overexploitation. Due to strong similarities in wood features...
Shallow land burial in vadose zone sediment at the Hanford Site in Washington is being considered for the disposal of Category 3 low-level waste. A series of column experiments were conducted to evaluate and model the performance of the soil surrounding the trench encasement material for iodine-129 and technetium-99 by...
The Long Tom Watershed Council (LTWC) is a non-profit organization in Eugene, Oregon that serves to protect and enhance watershed health in the Long Tom River Basin. The Amazon Creek Initiative was launched by the LTWC in 2011 as Oregon’s newest Pesticide Stewardship Partner. Goals of the initiative are to...
Debris flows, common disturbances in many mountainous areas, initially scour or bury stream habitats; however, debris flows deliver vast amounts of wood, boulders, and gravel that may ultimately form complex stream habitat to potentially support a diverse salmonid assemblage. The materials deposited by debris flows would otherwise be inaccessible to...
White and grand fir are both valuable components of the mixed-conifer stand structure managed for late-successional reserves in central Oregon. However, they are often short-lived species because of high susceptibility to root diseases, defoliating insects, bark beetles, and wildfire. This study focuses on the effects of root diseases caused by...
Many development organizations now recognize the importance of culturally sensitive project design and implementation. Unfortunately most of these groups continue to disregard the significance of gender. This qualitative research examines a women's cooperative in rural El Salvador which formed in order to find a means of generating income and to...
Increased automation and computerization have led to new demands and people are quickly transitioning to monitoring automated process and autonomous machines. Human oversight of automated process is important and desired, but people often require aid to navigate information from autonomous sources. An effective way to manage this information is with...
Hyperspectral images were taken from March till October, 2018, of southwestern white pine (Pinus strobiformis), SWWP, seedlings of ten different seed-source families. Half of the seedlings were inoculated with white pine blister rust (Cronartium ribicola). Visual assessments of vigor coincided with hyperspectral data acquisition.
The aim of the experiment was...
Schools are continually faced with the challenge of providing students with a comprehensive system of support. Previous research based on the practices and systems of Positive Behavior Intervention and Supports (PBIS) suggests that having effective primary prevention measures in place can help to reduce problem behavior before it occurs (Ingram,...
The evolving United States demographics, evident from the most recent census, show a steady population growth for Hispanics. Research suggests that after immigrating to the United States, first-generation Hispanic populations seem vulnerable to weight gain and development of chronic disease. Many health professionals recognize the increased need for Spanish language...
Childhood obesity has increased dramatically over the last several decades, particularly in industrialized countries, often accompanied by acceleration of pubertal progression and associated reproductive abnormalities (Biro et al., 2006; Rosenfield et al., 2009). The timing of pubertal initiation and progression in mammals is likely influenced by nutritional and metabolic state,...
Winter squash (Cucurbita maxima) grown in Oregon’s Willamette Valley for edible seed, frozen foods, and fresh markets is susceptible to an undiagnosed soilborne disease. Diseased squash fields exhibit symptoms of stunting, root and crown rot, vascular discoloration, and late-season wilt, which in extreme cases can lead to total crop failure....
Degradation of watersheds is a major concern in areas where adverse climate effects and unsustainable use of the natural resources have caused extensive stresses to watershed systems (e.g., increased floods, increased droughts, worsened in-stream water quality) through the years. While considerable efforts are being made to generate technical solutions that...
Individuals who have been traumatized have the opportunity to experience posttraumatic growth, conceptualized as positive changes that result from navigating highly challenging life circumstances (Tedeschi & Calhoun, 2004). The current model of posttraumatic growth (Calhoun, Cann, & Tedeschi, 2010) is based solely on cognitive-emotional processing yet by examining the role...
Young children with developmental disabilities (< 12 years old) participate less in physical activity (PA) and experience motor skill deficits compared to young children without disabilities (Jung, Leung, Schram, & Yun, 2018; Liu, Hamilton, Davis, & ElGarhy, 2014; Whyatt & Craig, 2012). When taking account of a bi-directional relationship between...
How can software practitioners assess whether their software supports diverse users? Although there are empirical processes that can be used to find “inclusivity bugs” piecemeal, what is often needed is a systematic inspection method to assess software’s support for diverse populations. To help fill this gap, this thesis introduces InclusiveMag,...
