Developing Anaerobic Digestion Cooperatives In Ireland, Aoife Ní Ruanaigh, John Mcgrory

Dissertations

Anaerobic Digestion (AD) is a natural process of decomposition and decay that takes place in the absence of oxygen and by which organic matter is broken down to its simpler chemical components. AD plants could help Ireland meet its requirements under a number of EU Directives as landfills release far more greenhouse gas emissions than other forms of waste treatment. It is estimated that 37 million tonnes per year of animal manure are stored on farms before disposal. There are also 676,000 tonnes of municipal food and garden waste produced annually. This waste could be used in AD plants to …

Vibration Based Technique For Monitoring The Postbuckling Deformation, Bashir Mustafa Ali

Dissertations

Structural health monitoring (SHM) is a technology whose objective is to detect damage growth in metallic and composite structural elements long before they reach critical dimensions. Most structural health monitoring approaches that have been developed in the past have confined their attention to material degradation such as cracks in metals and delaminations in composite materials. Buckling instability is another cause of catastrophic failure commonly seen in engineering structures. The objective of this study is to develop a technique capable of detecting the onset of buckling instability in structural members and assessing the margin of safety from final collapse. The technique …

Neuroendocrine Consequences Of Binge Alcohol Exposure During Peri-Puberty On Functioning Of The Hypothalamo-Pituitary-Adrenal (Hpa) Axis, Magdalena Malgorzata Przybycien-Szymanska

Dissertations

Binge alcohol (EtOH) exposure in adolescence is a fundamental health concern. In 2005, over 20% of teenagers between ages 15 and 17 reported binge drinking behavior within a one month period preceding the survey (Dept. of Health and Human Services: Substance Abuse and Mental Health Services Administration). Binge drinking is defined as consuming enough alcohol within a 2.0 h period to bring blood alcohol concentration above 0.08%. In the adolescent population, this type of alcohol exposure tends to be repeated. In adults, alcohol abuse has been correlated with increased incidence of mood disorders and these disorders are characterized by dysregulation …

A Salutogenic Framework To Understand Disparity In Breast Cancer Screening Behavior In African American Women, Regina Conway-Phillips

Dissertations

African American women (AAW) have the highest breast cancer mortality rate than any other racial or ethnic group. Limited access to care reduces mammography screening for AAW. Despite barriers, some AAW engage in breast cancer screening (BCS) behaviors like mammography. The salutogenic theory of health focuses on positive health behaviors and offers a framework to understand personal factors which allow some AAW to overcome adversity and engage in BCS. Sense of coherence (SOC) is central to salutogenic theory. Individuals with greater SOC utilize available resources to attain optimal health. This study: 1) Evaluated the contribution of SOC, social support and …

Dissertations

Jeffrey M. Courtright

THINKING THROUGH THE PHENOMENON OF TRUST: A PHILOSOPHICAL INVESTIGATION

The phenomenon of trust is historically underrepresented as a topic of serious investigation in Western philosophy. This dissertation investigates the integral role that trust plays in enabling and sustaining meaning and significance in human existence. This thesis is substantiated in the following ways.

First, I explicate various senses and ways of thinking about trust in the work of two historically important philosophers, Plato and Nietzsche. I show that Socrates, in Plato's dialogue Phaedo, articulates the feeling of being entrusted with life, a feeling that one experiences as a …

Sibling Suicide In Indo-American Families: Acculturation, Acculturative Stress, And Family Relationships, Suresh Unni

Dissertations

This study investigated suicide in Indo-American families. Relationships between acculturation, acculturative stress, and family relationships in completed suicides of Indo-American youth were examined. Snowball sampling procedures were used to find six adult sibling survivors of suicide as participants. Semi-structured, in-depth interviews were conducted by the researcher. Grounded theory strategies were used to analyze data and generate theory. Analysis of results yielded both protective and risk factors for suicide. Acculturation risk factors resulted from homogeneous populations lacking in diversity while protective factors were progressive and integrated neighborhood and schools. Integration was the preferred mode of acculturation by participants and suicide victims. …

The Holy Ghost Beyond The Church Walls: Latino Pentecostalism(S), Congregations, And Civic Engagement, Norman Eli Ruano

Dissertations

In what ways is Pentecostalism a catalyst or an inhibitor of congregational and congregant civic engagement among U.S. Latinos? And how does this compare to other religious traditions, specifically Latino Catholicism, Evangelicalism, and Mainline Protestantism? The dissertation argues that Latino Pentecostal congregations, depending on a variety of reasons such as demographics, and pastor's education, can either be very conservative, inward-looking, and otherworldly, or progressive and this-worldly--in addition to other options along this continuum. Such findings are particularly important given the common social scientific research assumption that Latino Pentecostal congregations are generally conservative, inward- looking, and otherworldly.

After surveying a representative …

Introducing The Common Good Index And A Common Good Immigration Ethic, Ana Bedard

Dissertations

The U.S. and Mexican bishops, in their influential pastoral letter Strangers No Longer, frame immigration ethics through the lens of solidarity with the immigrant. This frame leads them to erroneously interpret the preferential option for the poor and ignore potential harm to poor U.S. citizens caused by recent undocumented immigration from Mexico and other countries. A better framework to immigration ethics is a specified common good approach, which is created in this dissertation. This approach uses the definition of the common good found in Catholic social thought and concretizes it through using a theological anthropology based in Martha Nussbaum's human …

Patriarchy, Christianity, And The African Hiv/Aids Epidemic: Rethinking Christian Marriage In Light Of The Experiences Of Hiv Positive Women In Tanzania, Melissa Danielle Browning

Professional And Personal Lives Of Psychologists: Spillover, Family Functioning, And Life Satsiafction, Pedja Stevanovic

Dissertations

Two-wave, longitudinal data from a national, web-based survey of doctoral psychologists was used to examine work life, spillover, family, and personal lives. A measure of spillover, Stressors and Enhancers for Psychologists, was also evaluated. Confirmatory factor analysis indicated two negatively correlated dimensions of work spillover: positive spillover termed family enhancers and negative spillover termed family stressors. This measure was significantly related to a widely used, more general measure of positive and negative spillover and demonstrated high temporal stability. Respondents reported a significantly higher incidence of family enhancers than family stressors at both data collection points. Consistent with previous research, the …

Moving To The Level Of Representation To Explain Variations In Family Child Care Provider Sensitivity And The Effectiveness Of Child-Related Training, Diana Davidson Schaack

Dissertations

Many young children in the United States spend a substantial amount of time in the care of family child care providers. Previous research has found that when providers are sensitive and responsive to children's needs, children are more likely to develop secure attachment relationships with their providers, which, in turn, have been linked to many developmental benefits for young children. Unfortunately, it appears that many children do not experience the levels of caregiving sensitivity that are necessary to develop secure attachment relationships with their providers and that increased child-related training is not always effective at improving provider caregiving behaviors.

Attachment …

Black Club Women's Purposes For Establishing Kindergartens In The Progressive Era, 1890-1910, Jean Marie Robbins

Dissertations

Little literature exists that examines black people's efforts to educate their young children during the Progressive Era. It was the period in which early childhood education in the form of kindergarten began to flourish in the United States and around the world. Even in the abundance of literature about kindergarten's successes and its potential to transform impoverished families, the overwhelmingly poor black population remained invisible to the great majority of researchers writing about the progress of that movement.

Yet primary historical documents, such as the National Association of Colored Women's Clubs (NACW) records, manuscripts, and Progressive Era newspapers, reveal that …

Role Of Notch Signaling In T Cell Polarization, Shilpa Keerthivasan

Dissertations

The differentiation of CD4+ T cells to different effector lineages in response to pathogenic stimuli is the core of the adaptive immune system. One of the effector subsets recently discovered is Thelper 17 (Th17) and it plays a predominant role in autoimmune diseases and inflammatory disorders.

In my thesis, I aimed to study the role of Notch cell surface receptors in Th17 differentiation. Using in vitro Th17 differentiation assays of human naïve CD4+ T cells, I have shown that Notch signaling, particularly Notch1, plays a crucial role in Th17 polarization. By using pharmacological inhibitors and specific knockdown of Notch1, I …

Positive Peers: Exploring How And Why To Incorporate Peers Into Hiv Prevention Services, Allison Tan

Dissertations

In 2002, the Human Resource Service Administration (HRSA) began encouraging and funding a new strategy in HIV prevention. Referred to as Prevention with Positives (PwP), this approach to HIV prevention focused efforts on intervention with individuals who were already HIV-infected. This study examines one particular modality for the delivery of these important prevention messages to men and women living with HIV - the utilization of a peer-based model. "Peer-based" refers to any program which utilizes HIV-positive individuals as service providers for other HIV-positive individuals. A nationwide sample of such programs is used to provide an exploratory look into the possibilities …

Use Of Mushroom Extract To Enhance Quality And Health Benefits Of Dairy Products, Osman A. Hassan

Dissertations

Bifidobacteria and Lactobacilli are purportedly beneficial to human health and are called probiotics which are live microorganisms, when administered in adequate amounts conferring a health benefit on the host. It is believed that the maximum probiotics effect can be achieved if the organisms adhere to intestinal mucosal cells. Probiotics, perhaps in combination with prebiotics, may become an important means of preventing and treating disease. In fact, several types of diarrhea have been successfully treated with probiotics. The mechanisms behind favorable clinical outcome are still largely unknown, however, the potential benefits of probiotic therapy promise to be almost limitless. Organic acids …
