Risk Of Alzheimer's Disease Among Older Hispanic/Latinos With Diabetes, Kathy Bianco
Risk Of Alzheimer's Disease Among Older Hispanic/Latinos With Diabetes, Kathy Bianco
Walden Dissertations and Doctoral Studies
Alzheimer's disease (AD) is the 6th leading cause of death in older Americans. Currently there is no cure for AD, and even though the specific cause is unknown, diabetes mellitus type 2 (DM2) is regarded as a risk factor. Hispanics have a higher incidence of DM2 and possibly AD. I chose a life course theoretical model for this quantitative cross-sectional study to illuminate the variables most pertinent to a pathway from good health to poor health. The variables chosen were hypertension (HTN), obesity, smoking, stroke, dyslipidemia, and lower educational attainment. The research questions were used to examine biologic, metabolic, sociologic, …

Extending Two-Dimensional Knowledge Management System Theory With Organizational Activity Systems' Workflow Dynamics, Dana Forrest Ladd
Walden Dissertations and Doctoral Studies
Between 2005 and 2010 and across 48 countries, including the United States, an increasing positive correlation emerged between national intellectual capital and gross domestic product per capita. The problem remains organizations operating with increasingly complex knowledge networks often lose intellectual capital resulting from ineffective knowledge management practices. The purpose of this study was to provide management opportunities to reduce intellectual capital loss. The first research question addressed how an enhanced intelligent, complex, and adaptive system (ICAS) model could clarify management's understanding of organizational knowledge transfer. The second research question addressed how interdisciplinary theory could become more meaningfully infused to enhance …
Influence Of Mothers-In-Law On Infant Feeding Practices Of Mothers Living With Hiv In Rural Cameroon, Kenneth Ngwambokong Muko
Influence Of Mothers-In-Law On Infant Feeding Practices Of Mothers Living With Hiv In Rural Cameroon, Kenneth Ngwambokong Muko
Walden Dissertations and Doctoral Studies
Mothers living with HIV (MLHIV) face complex challenges regarding infant feeding practices, which often restrict their ability to adhere to their chosen or medically recommended feeding behaviors. Mothers-in-law (MIL) enjoy significant influence and participate actively in the rearing of grandchildren in Cameroon. However, the extent to which MIL influence infant feeding behaviors of their daughters-in-law have not been studied. The theory of planned behavior (TPB) was used in this phenomenological study to explore how attitudes, subjective norms, and perceived behavioral control influenced infant feeding practices of 9 MLHIV in rural communities of the North West Region of Cameroon. The five …
Phenotypic And Genotypic Characterization Of Lumbosacral Stenosis In Labrador Retrievers, Meenakshi Mukherjee
Phenotypic And Genotypic Characterization Of Lumbosacral Stenosis In Labrador Retrievers, Meenakshi Mukherjee
Graduate Theses, Dissertations, and Problem Reports (ETD)
Lumbosacral stenosis (LS) is a structural narrowing of the spinal canal in the canine lumbosacral spine. Large-sized working and sporting dog breeds such as Labrador retrievers are predisposed for reasons that are incompletely understood. Early diagnosis is essential for maximizing the quality of life, and minimizing the likelihood of early retirement in working dogs. Lumbosacral stenosis is usually considered to be a condition associated with degenerative changes observed with normal aging, however presence of the disease in young and middle aged working dogs has also been reported. This leads to the probable theory that some dogs in large breeds like …
Cardiac And Mitochondrial Impacts Of Acute Pulmonary Xenobiotic Exposure, Cody Edward Nichols
Cardiac And Mitochondrial Impacts Of Acute Pulmonary Xenobiotic Exposure, Cody Edward Nichols
Graduate Theses, Dissertations, and Problem Reports (ETD)
With every breath, we breathe in foreign materials, xenobiotic particles. These particles can interact with our tissues and influence the systems within. Airborne xenobiotic particles classically refer to ambient particulate matter (PM), but with technological advancement and the flourishing of nanotechnology, engineered nanomaterials (ENMs) have become entwined in the definition. Because the term xenobiotic particles encompasses particles with a broad range of size, shapes and chemical composition, definition of the properties that induce toxicity can be difficult, yet crucial to understand and predicting which of these characteristics is capable of inducing toxicity. This concept is crucial as nanotechnology moves forward …

Staff Perceptions Of The Effect Of The Leader In Me On Student Motivation And Peer Relationships In Elementary School, Charlene Tidd
Walden Dissertations and Doctoral Studies
Staff and student surveys at Lane Elementary School (pseudonym) confirm that students lack motivation to complete class work and often struggle to interact appropriately with one another. Similar concerns are reported across the United States as indicated by national Gallup Poll results on student motivation, peer relationships, and feelings of connectedness in schools. The purpose of this qualitative case study was to determine if elementary school personnel believe than an initiative called The Leader In Me has had a positive impact on student motivation and peer relationships. Underpinning this study were Perrin's student motivation theory and research on social and …
Hormonal And Social Factors Influencing Alternative Mating Tactic Decisions In Male Green Treefrogs, Hyla Cinerea, Brooks Pratt
Hormonal And Social Factors Influencing Alternative Mating Tactic Decisions In Male Green Treefrogs, Hyla Cinerea, Brooks Pratt
Honors Theses
In many anuran species (frogs and toads), males alternate between calling and a non-calling satellite mating tactic. Satellite males characteristically associate with calling males and attempt to intercept females that are attracted to the vocalizations of the calling host male. The prevailing hypothesis is that the decision to adopt a calling or satellite mating tactic is based on relative attractiveness — males are predicted to adopt a satellite mating tactic when the vocalizations of nearby males are more attractive than their own. In support of this hypothesis, previous studies have shown that satellite males can be induced to call by …

Elevated ALK4/5 ligands including TGF-β and activins have been linked to cardiovascular remodeling and heart failure. Doxorubicin (Dox) is commonly used as a model of cardiomyopathy, a condition that often precedes cardiovascular remodeling and heart failure. In 7-8-week-old C57Bl/6 male mice treated with Dox we found decreased capillary density, increased levels of ALK4/5 ligand and Smad2/3 transcripts, and increased expression of Smad2/3 transcriptional targets. Human cardiac microvascular endothelial cells (HCMVEC) treated with Dox also showed increased levels of ALK4/5 ligands, Smad2/3 transcriptional targets, a decrease in proliferation and suppression of vascular network formation in a HCMVEC and human cardiac fibroblasts …

Avian Fatalities At Wind Energy Facilities In North America: A Comparison Of Recent Approaches, Douglas H. Johnson, Scott R. Loss, K. Shawn Smallwood, Wallace P. Erickson
Avian Fatalities At Wind Energy Facilities In North America: A Comparison Of Recent Approaches, Douglas H. Johnson, Scott R. Loss, K. Shawn Smallwood, Wallace P. Erickson
Human–Wildlife Interactions
Three recent publications have estimated the number of birds killed each year by wind energy facilities at 2012 build-out levels in the United States. The 3 publications differ in scope, methodology, and resulting estimates. We compare and contrast characteristics of the approaches used in the publications. In addition, we describe decisions made in obtaining the estimates that were produced. Despite variation in the 3 approaches, resulting estimates were reasonably similar; about a quarter- to a half-million birds are killed per year by colliding with wind turbines.
Impact Of Wind Energy On Bats: A Summary Of Our Current Knowledge, Cris D. Hein, Michael R. Schirmacher
Impact Of Wind Energy On Bats: A Summary Of Our Current Knowledge, Cris D. Hein, Michael R. Schirmacher
Human–Wildlife Interactions
Since 2003, when it was discovered that large numbers of bats were being killed at wind turbines in the eastern United States, our understanding of the impact of wind energy development on bats has increased and consistent patterns of fatality, including seasonality and species composition have become evident. Yet, many questions remain despite the wealth of data collected across numerous post-construction monitoring studies. We synthesized the recent literature to provide an overview of our current understanding of patterns of bat fatalities at wind energy facilities in the United States and Canada. Our understanding of the impact of wind energy development …
Mitigating Wind Energy Impacts On Wildlife: Approaches For Multiple Taxa, Edward B. Arnett, Roel F. May
Mitigating Wind Energy Impacts On Wildlife: Approaches For Multiple Taxa, Edward B. Arnett, Roel F. May
Human–Wildlife Interactions
Mitigating impacts of wind energy development on wildlife is important for conservation and public acceptance of this energy source. We provide an overview of approaches to mitigate impacts of onshore wind energy development on wildlife, following steps in the mitigation hierarchy, including avoidance, minimization, and compensatory mitigation. Planning and avoiding predicted high-risk areas is fundamental to reduce impacts on birds and bats. Contrary to avoidance, once facilities are built, options to minimize impacts need to be tailored to species at the specifc site, and can be limited especially for bats. Curtailing wind turbine operations is the only approach proven effective …

Abc’S Bird-Smart Wind Energy Campaign: Protecting Birds From Poorly Sited Wind Energy Development, Michael Hutchins, Mike Parr, Darin Schroeder
Human–Wildlife Interactions
This article summarizes American Bird Conservancy’s (ABC’s) strategies and goals for achieving Bird-Smart wind energy in the United States. We describe the current and projected impact of wind energy development on birds and bats in the United States. We also discuss how bird (and bat) conservation goals could be made more compatible with wind energy development through improved science and regulation. We provide examples of poorly sited wind energy projects, existing and proposed, which call into question the efficacy of current voluntary federal permitting guidelines. We discuss the need for improved transparency and independent site-by-site pre-construction risk assessment, science-based decision-making, …
Adapting Strategies To Maintain Efficiency During A Cull Of Yellow-Legged Gulls, Sugoto Roy, Ray Ridley, Jeff Sandon, John R. Allan, Peter S. Robertson, Andrew Baxter
Adapting Strategies To Maintain Efficiency During A Cull Of Yellow-Legged Gulls, Sugoto Roy, Ray Ridley, Jeff Sandon, John R. Allan, Peter S. Robertson, Andrew Baxter
Human–Wildlife Interactions
Increasing populations of yellow-legged gulls (Larus michahellis) in the Mediterranean have created conflicts with seabird conservation, migrating raptors, and humans. As a mitigation measure, gulls are routinely culled in the region. Previous studies of extended culls show that catch per unit effort declines over time through a combination of population reductions and avoidance behaviors developing within the remaining population. We countered these problems during a 4-year cull of yellow-legged gulls in Gibraltar by matching the type and mode of deployment of firearms in response to changes in gull distribution and behavior. We found that shotguns were effective when …

Visual And Olfactory Concealment Of Duck Nests: Influence On Nest Site Selection And Success, Jennifer S. Borgo, Michael R. Conover
Human–Wildlife Interactions
Selecting a nest site is an important decision for waterfowl. Because most nest failure is due to depredation, the primary selective pressure in choosing a nest site should be to reduce depredation risk. This task is difficult, however, because predators use differing tactics to locate nests, such as olfactory or visual cues. The purpose of this research was to evaluate both the olfactory and visual components of waterfowl nest site selection and nest depredation in North Dakota. We located waterfowl nests, monitored them until termination (hatched or depredated), and collected both visual and olfactory concealment characteristics of nest sites and …

Impacts Of Coyote Removal On Space Use By Greater Sage-Grouse, Elizabeth K. Orning, Julie K. Young
Impacts Of Coyote Removal On Space Use By Greater Sage-Grouse, Elizabeth K. Orning, Julie K. Young
Human–Wildlife Interactions
Greater sage-grouse (Centrocercus urophasianus) are in decline across western North America. Identification of management strategies to enhance populations, such as predator management, may be needed to reduce further declines, but unintentional effects associated with increased human activity should also be considered. We evaluated the effect of 3 levels of predator management effort on greater sage-grouse space use. Home range size, movement rate, seasonal movement timing, and inter-seasonal distances traveled were examined as behavioral responses relative to levels of coyote removal in Bighorn Basin, Wyoming. We observed larger home range sizes during brood-rearing but overall smaller annual core (25% …

Influence Of Transmission Line Construction On Winter Sage-Grouse Habitat Use In Southern Utah, Erica P. Hansen, A. Cheyenne Stewart, S. Nicole Frey
Human–Wildlife Interactions
The construction and operation of electric power transmission lines (“power lines”) and their associated infrastructure has been identified as a conservation threat to the greater sage-grouse (Centrocercus urophasianus; sage-grouse). The conservation buff er zones recommended by state and federal agencies to avoid potential impacts on breeding populations diff er because information regarding the effects of power lines on sage-grouse is lacking. Little information is available regarding sage-grouse responses to power lines placed in winter habitat. Hence, we evaluated sage-grouse habitat use before and after construction of the Sigurd-Red Butte (SRB) 345-kilovolt (kV) transmission line in winter habitat. The …

Wind Energy Development: Methods For Assessing Risks To Birds And Bats Pre-Construction, Todd Katzner, Victoria Bennett, Tricia Miller, Adam Duerr, Melissa Braham, Amanda Hale
Human–Wildlife Interactions
Wind power generation is rapidly expanding. Although wind power is a low-carbon source of energy, it can impact negatively birds and bats, either directly through fatality or indirectly by displacement or habitat loss. Pre-construction risk assessment at wind facilities within the United States is usually required only on public lands. When conducted, it generally involves a 3-tier process, with each step leading to more detailed and rigorous surveys. Preliminary site assessment (U.S. Fish and Wildlife Service, Tier 1) is usually conducted remotely and involves evaluation of existing databases and published materials. If potentially at-risk wildlife are present and the developer …
Declining Populations Of Greater Sage-Grouse: Where And Why, Michael R. Conover, Anthony J. Roberts
Declining Populations Of Greater Sage-Grouse: Where And Why, Michael R. Conover, Anthony J. Roberts
Human–Wildlife Interactions
Scientists have been predicting the extinction of greater sage-grouse (Centrocercus urophasianus) since 1916, and sage-grouse populations have declined relentlessly during the last century despite attempts to reverse the decline. In this review paper, we examined the scientific literature to evaluate hypotheses about why sage-grouse populations have declined. There is little support for the hypotheses that the decline is due to overhunting, parasites, food shortages, or collisions with power lines or fences. West Nile Virus (WNV) reduced sagegrouse up to 25% when the virus first reached the West during 2002, but sage-grouse have developed resistance to the virus since …

Wind Energy Development: Methods To Assess Bird And Bat Fatality Rates Post-Construction, Manuela Huso, Dan Dalthorp, T. J. Miller, Dawn Bruns
Human–Wildlife Interactions
Monitoring fatalities at wind energy facilities after they have been constructed can provide valuable information regarding impacts of wind power development on wildlife. The objective of this monitoring is to estimate abundance of a super-population of carcasses that entered the area within a designated period of time. By definition, the population is not closed and carcasses can enter as they are killed through collision with turbines, and leave as they are removed by scavengers or decompose to a point where they are not recognizable. In addition, the population is not inherently mobile, but can only change location through some external …
