Claims of injustice in global forest governance are prolific: assertions of colonization, marginalization and disenfranchisement of forest-dependent people, and privatization of common resources are some of the most severe allegations of injustice resulting from globally-driven forest conservation initiatives. At its core, the debate over the future of the world's forests is fraught with ethical concerns. Policy makers are not only deciding how forests should be governed, but also who will be winners, losers, and who should have a voice in the decision-making processes. For 30 years, policy makers have sought to redress the concerns of the world's 1.6 billion forest-dependent poor by introducing rights-based and participatory approaches to conservation. Despite these efforts, however, claims of injustice persist. This research examines possible explanations for continued claims of injustice by asking: What are the barriers to delivering justice to forest-dependent communities? Using data collected through surveys, interviews, and collaborative event ethnography in Laos and at the Tenth Conference of Parties to the Convention on Biological Diversity, this dissertation examines the pursuit of justice in global forest governance across multiple scales of governance. The findings reveal that particular conceptualizations of justice have become a central part of the metanormative fabric of global environmental governance, inhibiting institutional evolution and therewith perpetuating the justice gap in global forest governance.

Nitrate from agricultural runoff are a significant cause of algal blooms in estuarine ecosystems such as the Chesapeake Bay. These blooms block sunlight vital to submerged aquatic vegetation, leading to hypoxic areas. Natural and constructed wetlands have been shown to reduce the amount of nitrate flowing into adjacent bodies of water. We tested three wetland plant species native to Maryland, Typha latifolia (cattail), Panicum virgatum (switchgrass), and Schoenoplectus validus (soft-stem bulrush), in wetland microcosms to determine the effect of species combination and organic amendment on nitrate removal. In the first phase of our study, we found that microcosms containing sawdust exhibited significantly greater nitrate removal than microcosms amended with glucose or hay at a low nitrate loading rate. In the second phase of our study, we confirmed that combining these plants removed nitrate, although no one combination was significantly better. Furthermore, the above-ground biomass of microcosms containing switchgrass had a significantly greater percentage of carbon than microcosms without switchgrass, which can be studied for potential biofuel use. Based on our data, future environmental groups can make a more informed decision when choosing biofuel-capable plant species for artificial wetlands native to the Chesapeake Bay Watershed.

In order to develop a strategic plan that will guide their priorities and resource allocation for 2018-2021, North Carolina Sea Grant has implemented a multi-stage process designed to increase stakeholder engagement and to better assess and serve the coastal priorities of North Carolinians. This project explores strengths and potential areas for improvement within NC Sea Grant’s planning process with a specific focus on maximizing stakeholder engagement. By interviewing staff, observing focus groups, and creating a survey instrument for public distribution, we developed a set of recommendations highlighting the ways that NC Sea Grant can better facilitate inclusion of stakeholder, public, and staff input in its strategic planning process, such as holding some stakeholder events outside of typical business hours and discussing ways to incorporate diversity into the strategic plan.

Research indicates that school leaders are crucial to improving instruction and raising student achievement (Council of Chief State School Officers, 2008). As such, educational reforms such as the No Child Left Behind Act (2001) and Race to the Top (2009) have sparked an accountability movement where principals are being held accountable for students' academic achievement and educational outcomes. The shift towards greater accountability has placed new attention on the ways principals are trained. Researchers have noted that organized professional development programs have not adequately prepared school principals to meet the priority demands of the 21st century (Hale & Moorman, 2003; Murphy, 1994). Murphy (1994) stated, "Traditional preparation programs - usually pre-service programs based in colleges or universities, that awarded certification and advanced degrees - rarely concentrated on the leadership challenges that principals actually face in real schools" (p. 4). As a result, many school districts are seeking ways to develop leadership development training programs that will prepare principals for their job responsibilities as a school leader. In spite of the additional training principals receive, researchers suggests that there is an obvious gap between the readiness of administrators to be instructional leaders and the demands for accountability that school administrators face (Hale & Moorman, 2003). This quantitative study examined elementary school principals' perceptions of their leadership development training program. Guided by four research questions, the study examined principals' perceptions of their overall training and how well their training prepared them to deal with school and classroom practices that contribute to student achievement; to work with teachers and others to design and implement a system for continuous student achievement; and to provide necessary support to carry out sound school, curriculum, and instructional practices. Data for this study was collected by way of survey responses from a total of 46 elementary school principals. The results from the study revealed that more than half (58.7%) of participants perceived their training as excellent. While principals' perceived that their training adequately prepared them to work collaboratively in teams, set clear visions and goals, and to use data to improve students achievement, many respondents reported a lack of training in being informed and focused on student achievement. Principals also suggested that they were not effectively trained in finding effective ways to obtain support from central office or community members.

El presente trabajo tuvo como objetivo evaluar el desempeno de tres cuchillas de corte y remoción en un suelo vertisol bajo siembra directa mediante la eficiencia de implantación y la velocidad de emergencia de un cultivo de soja. Las cuchillas utilizadas fueron: lisa, rippled y dura flute. La hipotesis de trabajo fue: la eficiencia de implantación y el dia medio a emergencia del cultivo de soja bajo siembra directa y en un suelo Vertisol son dependientes del tipo de cuchilla labrasurco que compone el tren de siembra de la sembradora. El ensayo se llevó a cabo en un establecimiento ubicado en el departamento de Gualeguaychu, sur de la Provincia de Entre Ríos, siendo sus coordenadas 32 grados 50 minutos 8.18 segundos latitud sur y 58 grados 40 minutos 05.69 segundos longitud oeste. Los principales resultados obtenidos señalan que el máximo logro, en cuanto al porcentaje de emergencia, se observa a los 13 días después de la siembra y luego hay una declinación en el stand de plantas hasta el dia 25 posterior a la siembra, siendo la cuchilla lisa la que mas se vio afectada. Las condiciones de alta humedad debido a las continuas precipitaciones sucedidas en el transcurso de la emergencia del cultivo afectaron el establecimiento de las plantulas de soja. Las conclusiones fueron: a) la cuchilla rippled produjo la mayor eficiencia de implantacion, b) la velocidad de emergencia de las plantas de soja fue superior en aquellas cuchillas que, ademas de cumplir con la función de cortar el rastrojo, generan una remoción de la línea de siembra, c) el día medio a emergencia resultó ser menor con la cuchilla dura flute, resultando ser mayor con la cuchilla lisa, d) donde se utilizó la cuchilla labrasurco lisa hubo una mayor muerte de plántulas por damping off.

Abortion politics are contentious and divisive in many parts of the world, but nowhere more so than in Ireland. Abortion and Nation examines the connection between abortion politics and hegemonic struggles over national identity and the nation-state in the Irish Republic. Situating the abortion question in the global context of human rights politics, as well as international social movements, Lisa Smyth analyses the formation and transformation of abortion politics in Ireland from the early 1980s to the present day. She considers whether or not the shifting connections between morality, rights and nationhood promise a new era of gender equality in the context of nation-state citizenship.
The book provides a new sociological framework through which the significance of conflict over abortion and reproductive freedom is connected to conflict over national identity. It also offers a distinctive in-depth consideration of the connection between gender and nationhood, particularly in terms of its impact on women's status as citizens; within the nation-state; within the European Union; and as members of a global civil society.
