Internalization Of Sociocultural Standards Of Beauty, Perception Of Career Barriers, Depression, And State Physical Appearance Anxiety Among College Women, Adrionia Molder
Graduate Theses, Dissertations, and Problem Reports (ETD)
Women experience barriers that impede progress in a career and career goals, resulting in reduced career-related outcomes. Although gender discrimination has been identified as a contributing factor to the differential career development of men and women in the United States (U.S.), women’s career-related outcomes may be better explained by unaccounted for career barriers. Most notably, internalization of sociocultural standards of beauty, depression, and anxiety have been found to reduce women’s career-related outcomes. Therefore, the goal of this study was to explore career barriers that currently impact women’s career development in the U.S. Based on Social Cognitive Career Theory (Lent, Brown, …
Multimorbidity, Immune Checkpoint Inhibitor Use, And Healthcare Expenditures Among Older Patients With Late-Stage Melanoma, Pragya Rai
Graduate Theses, Dissertations, and Problem Reports (ETD)
With decades of unchanged cancer care with no added survival benefit, immune checkpoint inhibitors (ICI) changed the treatment landscape of late-stage melanoma in 2011. A key factor in determining the use of ICIs is the presence of pre-existing chronic conditions, which can influence the outcome. However, the prevalence of multimorbidity (defined as presence of two or more chronic conditions) among older patients with late-stage melanoma remains unknown. It also remains unknown if the presence of multimorbidity factors into the use of ICIs. Hospital-related factors associated with ICI use have been studied. Yet, patient-level factors, such as age, sex, marital status, …

Role Centrality And Shared Activities With Grandchildren: Effects On Grandparent Wellbeing, Madeline Marie Marello
Role Centrality And Shared Activities With Grandchildren: Effects On Grandparent Wellbeing, Madeline Marie Marello
Graduate Theses, Dissertations, and Problem Reports (ETD)
Research shows that physical and mental health are closely linked (Ohrnberger, Fichera, & Sutton, 2017). Further, social role theory states that holding and enacting valued roles, such as grandparenting, can buffer the negative effects of health on depression (Reitzes & Mutran, 2004). Using data from 247 grandparents (Mean age = 66.5; range 42 to 90 years; 46.2% grandfathers), we examined whether grandparent role centrality and engagement with grandchildren altered the effects of physical health on depression. We then explored model differences between 164 custodial and 83 traditional grandparents. We found that for all grandparents the model was of sufficient fit: …

Scaling-Based Robust Predictions Of Periodic Stream Water Quality Variables Across The Contiguous U.S., Mohammad Abu Zafer Siddik
Scaling-Based Robust Predictions Of Periodic Stream Water Quality Variables Across The Contiguous U.S., Mohammad Abu Zafer Siddik
Graduate Theses, Dissertations, and Problem Reports (ETD)
Stream water quality is at the core of the biological and ecological health of streams and rivers. Subject to the environmental variation and in-stream metabolic activities, key water quality indicators such as dissolved oxygen (DO), water temperature (Tw), and chlorophyll a (Chl a, an indicator of primary productivity) typically follow a concave-shaped diurnal cycle. Variation and changes in climatic drivers (e.g., solar radiation, air temperature, and pressure), land uses, and hydrologic variables lead to a high spatiotemporal variability in stream water quality. The spatiotemporal variation challenges the development of robust models for predictions across large scales (e.g., county, state, country), …

Graduate Theses, Dissertations, and Problem Reports (ETD)
Operating companies in the unconventional Marcellus shale play have all faced a similar and problematic issue, while attempting to produce natural gas over the last decade. Companies have quickly realized that not every perforation along their horizontal wells are producing gas. In fact, producing perforations are only ranging from 15%-70% of the total perforations along the horizontal wellbore [1]. This unexplained issue results in millions of dollars in lost revenue per well, in addition to the sunk cost of paying for completions that are not actually yielding any produced gas.
What is causing these perforations to have no produced gas? …

Pulmonary Immune Responses To Respirable Elongate Mineral Particles Of Asbestiform And Non-Asbestiform Morphologies, Timur Khaliullin
Graduate Theses, Dissertations, and Problem Reports (ETD)
Inhalation exposure to asbestiform elongate mineral particles (EMPs) may cause pulmonary fibrosis, lung and pleural cancer. At the same time, epidemiological evidence for non-asbestiform EMP pathogenicity is scarce, with little if any risk of cancer, but consistent findings of pneumoconiosis and increased mortality. Globally, conditions caused by asbestos exposures contribute most to the occupational cancer burden and are responsible for the increasing mortality for occupational respiratory diseases. Immunological components of the fiber-induced lesions are extremely understudied, partly due to the lack of comparable test articles. In this study I utilized respirable preparations of asbestiform and non-asbestiform riebeckite and tremolite to …

Development, Analysis And Case Studies Of Impact Resistant Steel Sets For Underground Roof Fall Rehabilitation, Dakota D. Faulkner
Development, Analysis And Case Studies Of Impact Resistant Steel Sets For Underground Roof Fall Rehabilitation, Dakota D. Faulkner
Graduate Theses, Dissertations, and Problem Reports (ETD)
Underground mines often experience roof falls in entries, crosscuts, and intersections of active mining sections, main travel ways, and belt entries. Roof fall heights greater than 20 ft (6 m) make re-bolting of the newly exposed roof dangerous and impractical. To protect mine personnel, belts, moving vehicles, and other equipment, mine operators typically install steel structures such as square or arch sets in the roof fall areas. Wood lagging is usually installed between the steel-sets to enclose the area and protect the entry from recurring falls. Usually the void space above the steel-sets and wood lagging is backfilled. However, backfilling …
