The Imperatives Of Political Will For Revenue Diversification In Delta State Nigeria, Benson Chukwuweike Ojoko
Walden Dissertations and Doctoral Studies
Proceeds from crude oil export account for about 90% of the revenue of the federal, state, and local governments in Nigeria. Given the vagaries of the international oil market, scholars have advocated the need for the government to look beyond oil for other revenue sources with little or no success to date. Despite the plethora of research on the phenomenon of political will, there is no research on how the construct affects revenue diversification at the subnational level. This study examined how central political will is in the design of expansionary revenue policies in Delta State, Nigeria. Developing an understanding …
Homeowners’ Lived Experience In Developing And Using Accessory Dwelling Units In Ireland,

Walden University
Homeowners’ Lived Experience In Developing And Using Accessory Dwelling Units In Ireland, Geraldine Mary Hurley
Walden Dissertations and Doctoral Studies
Researchers have explored the role of accessory dwelling units (ADUs) as a form of housing since at least the 1970s. Such exploration has taken place across a number of different disciplines, including gerontology, housing affordability, and urban planning. The literature tends to focus on specific policies, however, rather than on the lived experience of the homeowners impacted by those policies. Ireland’s national and local governments have yet to acknowledge the potential use of ADUs as a contributing solution to ongoing problems with housing supply, housing affordability, and homelessness, despite a government-declared national housing crisis. Formal research on ADUs in the …

Corporate Social Responsibility In The United States And Nigeria, Olatokunbo Ahmed Wilfred Tijani
Walden Dissertations and Doctoral Studies
A recent spate of violations uncovered by international regulators has suggested an emerging social problem that the current corporate social responsibility (CSR) credibility paradigm could be decoupling between theory and practice. This development has left most stakeholders deliberating if CSR in practice is aligned with CSR in theory. This correlational research study empirically tested the CSR theory, positing improved corporate social performance (CSP) and corporate financial performance (CFP); and stakeholder theory, positing quid pro quo correlation between multinational corporations (MNCs) and their stakeholders. The purpose of this study was to identify if there is a positive association between the corporate …

Investigating Predation Risk Experienced By Wintering Birds At A Supplied-Food Garden, Madison Smart
Department of Environmental Studies: Undergraduate Student Theses
Wintering birds are particularly susceptible to predation while foraging at feeders. The ‘starvation vs. predation’ survival trade-off is felt most acutely in winter because energy demands are higher compared to milder seasons. This study investigated sense of predation risk experienced by members of a wintering mixed-species flock. The objective was to determine which species take on increased predation risk in order to forage at feeders, and if there was bias for one species over another. A raptor (experimental) and non-raptor (control) model were presented to a mixed-flock at feeders within Pioneers Park Nature Center. The first species to return to …

Decolonizing Food Systems Research – The Case Of Household Agricultural Food Access In Bikotiba, Togo, Katryna Maria Kibler
Antioch University Dissertations & Theses
Indigenous West African farmers are among the most climate change threatened globally. Food insecurity is prevalent in West Africa because ecological, social, political, and economic instabilities, and globalization worsen climate pressures. In this study, I collaborated with the community of Bikotiba (bih-CO-ti-buh), Togo, to understand their household agricultural food access, one aspect of resilience to food insecurity. I adopted a feminist approach of reflexivity, radical vulnerability, and radical empathy, combined with decolonizing principles, to argue that there could be an ethical way for well-trained Western researchers to engage Indigenous communities, if negotiated carefully. Together, Indigenous Research Assistants and I developed …
