"We Have Ground To Cover For Each Other": A Case Study Of Mentoring Across Black Sorority Alumni In North Central West Virginia, Elizabeth C. Dever

Graduate Theses, Dissertations, and Problem Reports (ETD)

Black sororities are much more than their stereotypes of stepping and partying. They are service organizations that have a deep impact on their communities and help shape the identities of their members. These organizations can be seen at Historically Black Colleges and Universities (HBCUs) and Predominately White Institutions (PWIs). Black sororities are different than their traditionally white counterparts because the majority of active time in membership occurs after graduation. This thesis utilizes a case study of Black sororities in North Central West Virginia and West Virginia University. In spaces lacking in diversity and inclusion, Black sororities can serve as a …

Experiences Of Arts And Humanities Students Engaging In Undergraduate Research, Carinna F. Ferguson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Deemed an important pedagogical tool by the Boyer Commission Report more than 20 years ago, undergraduate research (UR) has been found to increase students’ academic performance, retention, and pursuance of higher degrees. However, much of the existing literature on UR has focused primarily on student participation outcomes in Science, Technology, Engineering, and Mathematics (STEM) fields while disregarding those in other concentrations. The purpose of this study was to understand the experiences of arts and humanities students participating in UR by describing (1) their research activities, and (2) the meaning and value they assign to research.

Review Of Established And Emergent Methods For The Production Of C4 Olefins, James Matthew Koval

Graduate Theses, Dissertations, and Problem Reports (ETD)

Current production of C₄ olefins is dominated by naphtha cracking and butane dehydrogenation, but significant research interest is developing in alternate feedstocks due to an abundance of inexpensive natural gas and bioethanol. The current C₄ olefin production methods are costly, make use of already-depleted petroleum resources, and are often hazardous to workers, which forms the impetus for investigation into alternative methods and assessment of their viability as a future means of olefin production. Methods of natural gas conversion to higher order hydrocarbons are discussed, including Fischer-Tropsch synthesis and oxidative methane coupling, each of which could form the first …

Trees, Fungi, Insects: How Host Plant Genetics Builds A Community, Sandra Jeanne Simon

Graduate Theses, Dissertations, and Problem Reports (ETD)

Organisms, such as fungi and insects, can cause millions of acres of agricultural and forest damage, while others provide billions of dollars in ecological services such as education, aesthetic enjoyment, pollination, and gardening. Plant breeding and biotechnology can potentially help establish a balance between the proliferation of detrimental pests and attraction of beneficial insects. Variation in plant physiological and morphological characteristics are extremely important in the ability of host tissues to support many different types of organisms. When that variation is genetically heritable in a plant population, shifts in the underlying genes can have predictable consequences in structuring entire ecosystems. …

Barriers And Facilitators Of Seeking Psychological Help For Muslims In The United States, Sarah R. B. Milam

Graduate Theses, Dissertations, and Problem Reports (ETD)

Due to increased social, cultural, and political struggles for Muslims in the United States (MUS), affordable, accessible, and culturally appropriate mental health care is important for these individuals (Aloud & Rathur, 2009). MUS are an underrepresented group that use mental health services at low rates (Ciftci, Jones, & Corrigan, 2013; Khan, 2006). MUS, especially those with mental health concerns, hold a number of stigmatized identities, often including their race and ethnicity, religion, and mental health status that can result in discrimination (Ciftci et al., 2013). The purpose of this study was to examine factors related to self-stigma for seeking psychological …

Breast Cancer Associated Muscle Fatigue: Novel Targets To Improve Survival And Quality Of Life, Hannah Elizabeth Wilson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Women diagnosed with breast cancer (BC) currently represent the largest group of cancer survivors in the United States, accounting for over 20% of those living after a cancer diagnosis. Most BC survivors report an unusual degree of fatigue, which can present prior to diagnosis and continue for many years after treatment cessation. Recent studies show that deficits in muscle function predict shorter survival in cancer, perhaps due to the fact that fatigue is known to reduce a patient’s tolerance to anti-cancer therapies. Therefore, improving muscle function in BC patients has the potential to improve both quality of life and survival …

Early Black Poetry, Social Justice, And Black Children: Receptions Of Child Activism In African American Literary History, Tabitha Lashay Joy Lowery

Graduate Theses, Dissertations, and Problem Reports (ETD)

In spite of the substantial amount of critical work that has been produced on the recovery of early African American literature in the last few decades, our representations of black authors are still limited. Current studies of early African American poets privilege the identification of African American literature with resistance to slavery. This identification has persisted and has made the field one-dimensional. My dissertation provides reception histories of four early black poets—Phillis Wheatley, George Moses Horton, Frances Harper, and Paul Laurence Dunbar—to argue for and present an expansive understanding of African American literature. A thorough examination of these authors’ circulation …

The purpose of this qualitative multiple case study was to explore the decision-making processes of 3 small businesses in …

Prosocial Behaviors: The Influence Of Authoritarian Parenting Style On Adolescents’ Prosocial Behaviors Towards Friends And Strangers, Krista-Gay Shaniece Chantal Taylor

Graduate Theses, Dissertations, and Problem Reports (ETD)

Adolescence is the period of development of many negative and positive behaviors. On the positive side, prosocial behaviors are positive behaviors that become more prominent in adolescents. Many of the studies that explore prosocial behaviors have explored it during childhood rather than in adolescence. Additionally, few have assessed specific parenting styles, like authoritarian parenting and its influence on adolescents’ prosocial behaviors within distinct relationships. Therefore, the aims of this study were to assess how the maternal authoritarian parenting style is associated with adolescents’ prosocial behaviors. I also explored how the association between these two variables differ for friends and strangers …

An Examination Of The Suspensions Of Students Identified With A Learning Disability, Shelly Ann Brooker

Walden Dissertations and Doctoral Studies

Students’ disruptive behaviors in the inclusive classroom that are detrimental to the learning environment can eventually elicit exclusionary consequences from general and special education teachers. The recent implementation of the Positive Behavioral Interventions and Supports (PBIS) in the local school district has behavioral outcomes for the students identified as learning disabled. The purpose of this study was to gather and examine information regarding the implementation of PBIS and how the application supports local students identified with a learning disability (LD) receiving excessive suspensions due to their disruptive behavior. This study was guided by Skinner's theory of operant conditioning and Ross' …

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: …

Investigation Of Particle Measurement In Different Dilution Ratios With Gasoline Direct Injection And Port Fuel Injection, John Adam Phillips

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ambient air quality has been a concern in the United States since the mid-1900’s, forcing legislations like the Air Pollution Control Act and Clean Air Act necessary to bring focus on air pollution and quality. The Environmental Protection Agency (EPA) continues to update the requirements for more efficient vehicles and emissions sampling methods. Today the EPA has implemented regulations on modern spark ignited engines without any major focus on the type of injection technologies being used. While particle matter (PM) is a requirement to measure for a vehicle certification, more research should focus on the particle number (PN) measurements that …

A Phenomenological Study: Police Officers’ Lived Experiences With The Use Of Ceds, Gustavo Alejandro Escalante

Walden Dissertations and Doctoral Studies

The use of conducted energy devices (CEDs; e.g., TASER) in the U.S. has increased significantly since their endorsement by the police in the 1990s. Police administrators have struggled with CED placement in use of force continuums, and citizens have voiced concerns regarding their disproportionate use and health effects. An increase in understanding of the value of CEDs, specifically the devices’ role when used as a threat only, provides police administrators with more significant insights regarding their appropriate placement in department policies, which leads to more proportionate use by police officers. This phenomenological study explored police officers’ lived experiences involving displaying …

Prevalence Of Pores In Latent Fingerprints, Rachel E. Ball

Graduate Theses, Dissertations, and Problem Reports (ETD)

Of the many biometric traits recognized today, fingerprints are the most prevalent and familiar. The analysis of fingerprints involves level 1, level 2, and/or level 3 detail in the identification of a potential match. Traditionally, fingerprint matching was completely performed by hand, utilizing the ACE-V method. Thanks to the development of rapidly evolving technology, fingerprint matching has become an automated procedure through the use of fingerprint matching algorithms. In the literature, there has been an increase in the interest of developing Automatic Fingerprint Identification System (AFIS) algorithms that include level 3 details in the matching process. These studies have utilized …

Low-Income Household Adults Sustaining Affordable Housing In Affluent Neighborhoods, Edward Brian Flournoy

Walden Dissertations and Doctoral Studies

Public housing policy continues to exacerbate the concentration of poverty for low

income household adults (LIHA), preventing their mobility to achieve or sustain

affordable housing in low-poverty affluent neighborhoods. Successful design and

implementation of public housing policy for LIHA has been elusive for policymakers

seeking to address socioeconomic self-sufficiency problems in the United States.

Wilson’s spatial mismatch theory on social transformation of the inner city was the

theoretical framework for this study. This qualitative study utilized policy analysis and

key interviews to explore the importance of public policy design and implementation in

how the Moving to Opportunity (MTO) program influenced …

Capillary Electrophoresis Analysis Of Proteins Using Phospholipid Based Materials, Cassandra L. Crihfield

Graduate Theses, Dissertations, and Problem Reports (ETD)

Capillary electrophoresis has many advantages that make it a powerful technique for the analysis of proteins, which is challenging due to the natural heterogeneity of proteins. The small sample volume required for each analysis (nano- and pico-liter), fast separation times (<30 >min), and ability to couple the separation to mass spectrometry are all factors that make capillary electrophoresis an ideal technology for protein separations. Capillary zone electrophoresis and capillary gel electrophoresis are the two most commonly employed modes for protein analysis and allow for rapid, high resolution separations that can be automated. This makes capillary electrophoresis ideal for meeting the …

Process Development Of Shale Gas Assisted Lignin And Biomass Reforming Through Novel Reaction Pathway And Catalyst Design To Produce Hydrogen Rich Syngas For Fuels And Value Added Chemicals, Amoolya D. Lalsare

Graduate Theses, Dissertations, and Problem Reports (ETD)

Novel biomass reforming strategy through synergistic co-processing with flare gas (methane and carbon dioxide) was developed at West Virginia University. Hardwood biomass comprised of lignin, hemicellulose, and cellulose is abundant in the US and potentially a sustainable source of hydrogen through extensive reforming and gasification. Ever-increasing shale gas production in the US occasionally leads to flaring owing to stranded production across the US. Achieving biomass co-processing with natural gas about to be flared in such stranded shale plays is the underlying motivation here. A novel reaction pathway was discovered wherein methane and carbon dioxide assisted reforming of biomass could be …

Speech Mode Classification Using The Fusion Of Cnns And Lstm Networks, Pratyusha Chowdary Vakkantula

Graduate Theses, Dissertations, and Problem Reports (ETD)

Speech mode classification is an area that has not been as widely explored in the field of sound classification as others such as environmental sounds, music genre, and speaker identification. But what is speech mode? While mode is defined as the way or the manner in which something occurs or is expressed or done, speech mode is defined as the style in which the speech is delivered by a person.

There are some reports on speech mode classification using conventional methods, such as whispering and talking using a normal phonetic sound. However, to the best of our knowledge, deep learning-based …

Central Appalachian Understory Red Spruce (Picea Rubens Sarg.) Growth Rates And Allometric Relationships, Joseph M. Gray

Graduate Theses, Dissertations, and Problem Reports (ETD)

Red spruce (Picea rubens) was a prized timber species in West Virginia during the era of resource exploitation in the late 1800s and early 1900s. Consequently, Central Appalachian red spruce has faced large reductions in range and changes in stand composition. This region is relatively underrepresented in literature partially due to these constrictions. Investigating how stem growth occurs in young individuals can fill in some of our gaps in understanding the species and aid in restoration efforts. We sampled an array of high elevation sites on federal and state lands in West Virginia to analyze understory spruce growth …
