Evaluating U.S. Federal Marine Protected Areas Programs: A Comparative Analysis And Conceptual Framework, Rosemarie Ann Bradley

Antioch University Full-Text Dissertations & Theses

Federal area-based marine protection and management in the United States is overseen by the National Marine Sanctuary Program, the National Estuarine Research Reserve System, the National Wildlife Refuge System, the National Park Service, and the National Marine Fisheries Service. Each agency and program represents a different approach to managing the oceans. Currently, no federal agency or program is responsible for evaluating the overall effectiveness of these programs. Evaluation is needed to determine whether programs are achieving their management objectives and conservation goals. Although evaluation protocols are legislatively mandated, implementation is inconsistent across programs.

Federal agencies have been criticized for failing …

Dwelling, Walking, Serving: Organic Preservation Along The Camino De Santiago Pilgrimage Landscape, Mercedes Chamberlain Quesada-Embid

Antioch University Full-Text Dissertations & Theses

This study is an exploration of the people and the landscape of the well-known Camino de Santiago pilgrimage route. Although there are many routes that make up the entirety of the pilgrimage, this research is specifically focused on the landscape of the Camino Francés, or French Route, in northern Spain. The path has been written about in many ways and for a myriad of reasons since it became affiliated with the Christian tradition in the early ninth century. This research, however, is different. By way of an environmental history and hermeneutic approach, an investigation of the interrelated and overlapping human …

Connecting With Nature Through Land Use Decision Making, Cathy Setterlin

Antioch University Full-Text Dissertations & Theses

This narrative inquiry, which draws on my experience as a land use decision maker, environmental educator, and scholar, examines the complexities of our human-nature relationship as we use and protect the life of the land in local communities. I began this research by interviewing seventeen land use decision makers representing a range of land use perspectives in New Milford, Connecticut, focusing on their views of land as a living community, their connections to land, and their sense of duty and responsibility.

Their responses led me to further inquiry and drew me into a process that transformed my views of both …

Integration Of Analysis And Deliberation To Evaluate Biodiesel Occupational And Environmental Exposures, Nora M. Traviss

Antioch University Full-Text Dissertations & Theses

Many U.S. organizations interested in a renewable and domestic source of energy are considering switching from petroleum diesel to biodiesel blends for transportation and heavy-duty equipment use. Biodiesel is a fuel made from vegetable oils or waste grease. While there is a considerable body of evidence on the negative health effects of petroleum diesel exhaust exposures in occupational and urban settings, there has been little research examining the impact of biodiesel fuel on occupational and environmental exposures. This dissertation combined a collaborative exposure assessment of B20 (20% soy-based biodiesel/80% diesel) at a rural recycling center with a policy intervention to …

The Ecology Of Paradox: Disturbance And Restoration In Land And Soul, Rowland S. Russell

Antioch University Full-Text Dissertations & Theses

This heuristic study explores environmental disturbance and ecological restoration in several North American settings in order to uncover epistemological, philosophical, aesthetic and ethical considerations revolving around those place-based processes. With fire as one of the central metaphors of this work, the initial place-based chapter examines Northern New Mexico's Pajarito Plateau to explore the region's fire ecology. The study then moves to the Pacific Northwest to draw restoration practice that attempt to restore wild salmon to urban Seattle habitat. The third place-based chapter focuses on the Midwest grass and farmlands in order to investigate the seeming contradictions between commodity and diversity …

Beyond The Debate: Exploring The Underlying Values And Assumptions Of Biodiversity Conservation In Protected Areas, Leon-Charl Malan

Antioch University Full-Text Dissertations & Theses

This dissertation examines the current disagreement among scientists and scholars about best practices for biodiversity conservation in protected areas. There is no clear consensus among the scientific community about the most effective approach to conserve biodiversity and several conflicting positions form part of an ongoing debate in the field. Most disagreements and conflicts are based on differences in the underlying values and assumptions of the parties involved in the conflict. The more we know and understand those underlying values, the more constructive the dialog, and the more likely acceptable policy decisions will be developed. This study, presented in three parts, …

Fostering Sustainability In Higher Education: A Mixed-Methods Study Of Transformative Leadership And Change Strategies, Kim H. Mcnamara

Antioch University Full-Text Dissertations & Theses

As evidence of the earth’s limited capacity to sustain human life mounts, institutions of higher education are being looked to for leadership in the effort to educate students about environmental concerns and support the development of sustainable innovations. Colleges and universities are responding to this call for leadership by starting and/or expanding environmental research programs, integrating sustainability issues throughout the curriculum, adopting sustainable operations, and building green facilities. Reflecting upon the sustainability efforts of these institutions, this research study explores the following questions: What factors are essential for initiating and leading a successful change effort to foster sustainability in higher …

Roots And Remedies Of Ginseng Poaching In Central Appalachia, Randi Jeannine Pokladnik

Antioch University Full-Text Dissertations & Theses

Ginseng, panax quinquefolius, is a perennial plant found in the understory growth of mesophytic forests of Appalachia. Illegal harvesting of the plant from both wild and cultivated populations has become very problematic for public land managers and private landowners engaged in cultivation of the species. Techniques aimed at curtailing the incidents of poaching have only been moderately successful. Given the economic value of the plant, its cultural significance, and the dramatic decrease of wild plant populations, it has become increasingly important to address this problem.

Several studies have linked illegal wildlife harvesting to economic problems, inadequate policies or laws, and …
