Abstract:
The management and utilisation of resources in agroforestry systems are influenced by both land and tree tenure systems, especially where land and tree tenure are distinct, and rights to one do not necessarily lead to rights over the other. Most academic research has examined the impact of land tenure on management and productivity in these landscapes. This thesis investigates the impact of tree tenure alongside other socioeconomic factors through the research question: 'how do local institutional arrangements affect the management, utilisation and ecology of indigenous economic trees in agrof

Abstract:
Shea butter production in West Africa has been dominated by women and Northern Ghana specifically is a leading global producer. This thesis explores women’s perceptions of power, control and agency in the Ojoba Women’s Fair Trade Co-operative in Upper East Ghana. I add to the literature on women’s experiences with and in fair trade. I examine how the shea industry and the co-operative provide a marketplace for women and a space for women to co-operate and resist power structures. I emphasize how the Western language of empowerment builds substantially from pre-existing women’s networks and lab

Abstract:
This study was conducted as a second part in the shear damage research project at Virginia Tech. The objectives were to verify the results obtained by Gallagher (1984) in the first study under normal mill operations as well as develop a method to compare and evaluate the extent of shear damage in relation to other defects present in southern pine lumber. This was accomplished through two sawmill studies and two kiln cart surveys performed in different geographic locations. Visible indicators such as stump-pull that are used to determine shear damage extent are often misleading. Stump-pull, u

Abstract:
This thesis analyzes eight specific Swedish medieval ballads that contain supernatural transformation and hybridity for how they depict gender in late medieval and early modern contexts. Using literature as a historical resource and a micro-historical approach, this thesis applies gender theory, intersectional approaches, and monster theory to its reading of these ballads. Through this analysis, this thesis has found that transformation in these ballads highlights what it meant to be human in the late medieval and early modern periods, by contrasting and defining humanness through the tension
