Historically fire has been the primary disturbance factor in the sagebrush-steppe. The settlement of the West by Euro-Americans, grazing by domestic livestock, and the concomitant spread of invasive species have altered the historical fire regime. Understanding the long-term vegetation structure and fuel succession of the various sagebrush-dominated communities of this...

The purpose of this study was to examine the evidence of construct validity for self-report with assistance from a secondary source as a measure of physical activity (PA) in adults with intellectual disabilities (ID) in free-living environments. Thirty-seven participants (21 females, 16 males) with mild to moderate ID aged 19-74...
We assessed the effects of the elimination of livestock in riparian systems at Hart Mountain National Antelope Refuge in southeastern Oregon, 23 years after the removal of cattle grazing, using 64 photos taken before grazing was removed compared with later retake photos. Two methods were used for this assessment: (1)...
Monitoring physical activity has been a dominant topic of research for many years. Being physically active has been shown to decrease health related issues, including obesity, cardiovascular disease, and even premature death. Multiple researchers have studied monitoring physical activity, but the actual method of measuring physical activity in a free-living...
Introduction: The health benefits of physical activity are well established in older adults with arthritis. Despite these benefits, many older adults with arthritis are not active enough to maintain health; therefore, increasing physical activity in adults with arthritis is a public health priority. The purpose of this study was to...
There is a knowledge gap concerning the outcomes of early adolescent sexual initiation (ASI). In particular, the influence of early ASI upon adult attachment is unknown. A multiple regression study was conducted to address this knowledge gap. Adult partner/spouse attachment was the criterion variable, and the predictor variables included both...
Our nation's schools are in a key position to promote regular physical activity
through participation in quality physical education programs (Sallis & McKenzie,
1991). The ultimate long-term demonstration of each program's impact is the
students' maintenance of an active lifestyle. Physical educators are consistently
attempting to find different ways to...
The importance of physical activity is well documented (Haskell et al., 2009a; McReynolds & Rossen, 2004; Steinbeck, 2001). Despite physical activity’s benefits, many individuals are not meeting current weekly physical activity guidelines recommending ≥ 150 minutes of moderate or ≥ 75 minutes of vigorous aerobic physical activity and 2 or...
Eliminating physical activity disparities among ethnic minorities in the U.S. is important. Cultural differences have been found to be plausible contributing factors associated with such disparities. Therefore it is important to investigate and understand the mechanisms by which diverse aspects of cultural experiences affect physical activity participation among ethnic minorities,...
Not all experiences in physical activity, exercise, and sport are positive. Losing, getting injured, making a mistake, and not measuring up can all elicit a variety of highly negative emotions, including shame. To make matters worse, individuals often cope with shame in maladaptive ways––magnifying, suppressing, or ignoring the experience––which can...
The western United States has experienced large-scale degradation due to land use and land cover changes, invasion of annual grasses, and expansion of woody plants into grass and shrublands and the resultant altered fire regimes. These landscape-scale changes have coincided with declining mule deer (Odocoileus hemionus) populations, making habitat loss...
Remote sensing techniques have long been useful in quantifying changes in ecosystems and the field of remote sensing is constantly evolving to better assess and describe changes, both spatially and temporally. In this thesis I explored the novel use of two remote sensing methods to quantify ecosystems; repeat photograph to...
Vietnam is considered one of the most climate change-vulnerable countries due to its high dependence on agriculture and its coastal location. Increased atmospheric temperatures caused by climate change also significantly threaten one of Vietnam's most important cash crops, robusta coffee (Coffea canephora). Suitable cultivation sites of robusta, which comprises 97%...
Walking is the most popular type of physical activity among the adult population in the United States including individuals with disabilities. Considering the popularity of the activity, walking-related physical activity should be a focus of health promotion campaigns among the adult population. Rhodes and Nigg (2011) suggested that employing theory-based...
This study focuses in providing the knowledge on carbon (C) stocks, emission and ecosystem productivity related to land use/land cover change in tropical peatlands. The field research activities were conducted for about 17 months between August 2013 to December 2015, at Pematang Gadung peat dome (peat depth up to 10.5...
It has been demonstrated that walking is the most common form of physical activity for adults with intellectual disabilities, including Down syndrome (DS). The pedometer is common measurement tool to quantify steps walked, yet there is little evidence of the psychometric properties for individuals with intellectual disabilities, particularly DS. Thus,...
Over the past few decades, a primary focus has been on the negative health effects of not participating in regular moderate-to-vigorous physical activity (MPVA). Only recently has sedentary behavior been studied as a distinct and independent risk factor for adverse health outcomes. This dissertation sought to provide new insights into...
Although electronic medical records systems (EMR) present promising benefits, they have not yet been widely adopted. A problem facing many EMR are that they are disruptive technologies; their complex hardware and software are not designed to account for the clinicians' characteristics and needs, thus, demanding a steep learning curve and...
The Mahakam Delta which was once among the largest mangrove forests in Indonesia, has been subjected to dramatic changes in structure and function due to massive shifts from mangrove forest to shrimp ponds and oil and gas development. To understand the impacts of mangrove loss to the greenhouse gas (GHG)...
This dissertation addresses gaps of knowledge associated with how ecosystem carbon stocks and greenhouse gas emissions are affected by land use land cover change in tropical peatlands. This was the first study that paired peat swamp forests with oil palm plantations and analyzed site scale variation on greenhouse gas emissions....
Organizational values are an important factor in the work of many organizations and can guide both day-to-day decision-making and long-term strategic planning. Little previous research has documented the impact of core values on individual performance in military environments nor the effect of core values on leadership attributes. In this study,...
The central goal of this study was to assess Venezuelan parent attitudes toward specific areas of parent-child
relationships such as child creativity, child play,
parental sense of frustration in childrearing, the amount
of parental control exercised over their children, and

own children....
Brewers' spent grain (BSG), the byproduct from beermaking, is a good source of protein and dietary fiber and may be utilized as a functional ingredient for food applications such as bakery goods. Starch-based film is well-known for its safety, edibility, and renewability. Starch films with the incorporation of cellulose nanofiber...
The role that anthropogenic and natural habitats in estuaries play in long-term population trends for Oregon’s nearshore marine fishes is poorly understood, in part due to limited temporal sampling. One important nearshore marine group is northeastern Pacific rockfishes (Sebastes spp.), which are highly diverse, with around 96 documented species, and...
In the realms of psychology and sociology two new theoretical models have arisen to describe the forces influencing altruistic human behavior. The first is the Empathy-Altruism Hypothesis (EAH), by C.D. Batson. The second is the Conceptual Continuum of Altruism (CCA), by K.R. Monroe. Both models have proven to be highly...
