Wabanaki Access To Sweetgrass (Hierochloe Odorata) Within Coastal Maine's Diminishing Open Land Tradition, Amanda Marie Ellis

Electronic Theses and Dissertations

Nontimber forest products (NTFPs), refer to a class of resources (i.e. moss, fungi, mushrooms, plants, etc.) gathered in both rural and urban landscapes. NTFPs are utilized by a variety of cultures all over the world and are a critical part of medicinal, spiritual, dietary, and economic practices. In fact, some NTFP species are so critical to people that they are considered ‘cultural keystone species’ (Garibaldi and Turner 2004). This designation means that without access to the NTFP, cultural survival is at risk. This is the case in Maine where the Wabanaki, a confederacy of four tribes (Passamaqouddy, Penobscot, Mikmaq, and …

Sperner's Lemma, The Brouwer Fixed Point Theorem, The Kakutani Fixed Point Theorem, And Their Applications In Social Sciences, Ayesha Maliwal

Electronic Theses and Dissertations

Can a cake be divided amongst people in such a manner that each individual is content with their share? In a game, is there a combination of strategies where no player is motivated to change their approach? Is there a price where the demand for goods is entirely met by the supply in the economy and there is no tendency for anything to change? In this paper, we will prove the existence of envy-free cake divisions, equilibrium game strategies and equilibrium prices in the economy, as well as discuss what brings them together under one heading.

This paper examines three …

Improving The Performance Of Ice Sheet Modeling Through Embedded Simulation, Christopher G. Dufour

Electronic Theses and Dissertations

Understanding the impact of global climate change is a critical concern for society at large. One important piece of the climate puzzle is how large-scale ice sheets, such as those covering Greenland and Antarctica, respond to a warming climate. Given such ice sheets are under constant change, developing models that can accurately capture their dynamics represents a significant challenge to researchers. The problem, however, is properly capturing the dynamics of an ice sheet model requires a high model resolution and simulating these models is intractable even for state-of-the-art supercomputers.

This thesis presents a revolutionary approach to accurately capture ice sheet …

Social Ecological Food Systems: Sustainability Lessons From Maine Dairy Networks, Julia B. Mcguire

Electronic Theses and Dissertations

Milk production has played an integral role in the culture, landscape, and economy of Maine’s agriculture. Maine dairy farmers have faced numerous sustainability challenges to economic, environmental, and social aspects of their industry. Like many other complex social ecological systems, the Maine dairy industry faces a gap between scientific knowledge and actionable management or policy. A cultural dichotomy exists between conventional and organic farming. Shifting the focus from this binary, metrics such as social capital may play a key role in solving sustainability issues. Difficulties arise in the governance of complex social ecological systems when the scales of assessment, management, …

Predicting Relationship Satisfaction In Same- And Cross-Sex Friendships, Hannah Ford

Electronic Theses and Dissertations

Friendships between members of the opposite sex become more common and increase in importance across adolescence (e.g., Kuttler, La Greca, & Prinstein, 1999); however, little research has examined these relationships. Of the limited research, most has focused on comparing mean-level differences in friendship features between cross-sex (CS) friendships and same-sex (SS) friendships. Overall, this research has suggested that CS friendships are lower in positive quality compared to SS friendships. These findings offer little insight into why CS friendships continue to be valued and maintained.

The current study used two approaches to better elucidate the value of CS friendships in a …

Anxiety Sensitivity And Decision Making: Positive And Negative Risk Taking In Laboratory And Naturalistic Settings, Amanda Kutz

Electronic Theses and Dissertations

As a group, anxiety disorders represent the most prevalent mental health condition. A hallmark feature of anxiety disorders is avoidant behavior. Along with this, anxious individuals have been shown to exhibit a risk aversion in decision making. However, anxiety disorders are simultaneously highly co-morbid with substance use disorders (e.g., Grant, Stinson, Dawson, & Chou, 2004), suggesting that certain individuals with anxiety disorders engage in particular forms of risk taking. However, much of the current literature on anxiety and risk taking has focused on risk aversion in anxiety, presupposing an inhibited model of anxious responding. In addition, there is little literature …

Safety, Recreation, And Visitation: An Economic Analysis Of Decision-Making On Coastal Beaches, Abigail Kaminski

Electronic Theses and Dissertations

Coastal beaches are important economic, social and cultural assets, hosting a variety of recreation activities ranging from wading in calm shallows to surfing in rough waters. Those who recreate on beaches often travel great distances to visit, suggesting that they place a high economic value on these resources. Despite the economic and cultural significance of beaches, little is known about the diversity of beachgoers and the ways they seek out safety information and make decisions on and between beaches. Safety risks are experienced differently across groups of beachgoers; those at higher risk of illness or injury include children, the elderly, …

The Role Of Electronic Communication Processes Across The College Transition: Relations To The Maintenance And Formation Of Friendships, Psychological Well-Being, And College Adjustment, Patricia E. Dieter

Electronic Theses and Dissertations

Friendship experiences play a vital role in the adjustment of adolescents. Late adolescents transitioning to college negotiate the important developmental tasks of both maintaining close hometown friendships and developing new college friendships. Electronic communication has become a prevalent way to quickly and easily communicate, and friendships that incorporate electronic communication with in-person communication are higher in quality (Baiocco et al., 2011). For some adolescents, however, Internet use becomes excessive and problematic (Ha et al., 2007).

The purpose of this investigation was to examine how individuals use different communication technologies with their existing hometown friends and their newer college friends, and …

Communicating Who Knows What In Sustainability Science: Investigating The Role Of Epistemology In Science Communication And Engagement, Brianne M. Suldovsky

Electronic Theses and Dissertations

The complex socio-ecological problems we face today often require that researchers collaborate with individuals and organizations outside of their own disciplines and, oftentimes, outside of academia entirely. This sustainability science model encourages university researchers to engage in participatory models of engagement, where nonscientific publics and scientists working outside of academe are invited to co-produce knowledge and, through collaboration, arrive at solutions for sustainability. Despite the popularity of participatory models of engagement in sustainability science, very little research has examined sustainability science researchers’ perceptions of epistemic authority in conjunction with their engagement behavior. This kind of work is important given that …

Social And Ecological Factors Affecting The Adoption Of Aquaculture, Karen Pianka

Electronic Theses and Dissertations

Commercial fishermen in Maine are increasingly dependent upon the American lobster fishery, and this reliance on a single species poses a threat to working waterfronts. Aquaculture represents a potential opportunity for commercial fishermen to diversify their income. Literature on the adoption of innovation suggests that factors such as age, education level, fishing experience, diversification, and leadership are important predictors of early adoption of innovation. However, few studies have examined whether such factors affect the adoption of aquaculture by commercial fishermen. Our marine policy research studied fishermen enrolled in two pilot shellfish and seaweed aquaculture classes held in 2013 in Harpswell …

Evaluation Of Multi-Level Cognitive Maps For Supporting Between-Floor Spatial Behavior In Complex Indoor Environments, Hengshan Li

Electronic Theses and Dissertations

People often become disoriented when navigating in complex, multi-level buildings. To efficiently find destinations located on different floors, navigators must refer to a globally coherent mental representation of the multi-level environment, which is termed a multi-level cognitive map. However, there is a surprising dearth of research into underlying theories of why integrating multi-level spatial knowledge into a multi-level cognitive map is so challenging and error-prone for humans. This overarching problem is the core motivation of this dissertation.

We address this vexing problem in a two-pronged approach combining study of both basic and applied research questions. Of theoretical interest, we investigate …

Analysis Of Japan's Rta And Wto Dispute Settlement Mechanism, Shunsuke Sato

Electronic Theses and Dissertations

This thesis analyzes Japan’s decision to use Dispute Settlement Mechanisms (DSMs) in trade agreements. International trade rules are effective when properly applied: they prevent abrogation of the obligations that come with membership in international economic organizations. The DSMs are important ways to enforce the international trade commitments agreed upon by signatory countries. To date, member countries have filed more than 500 cases through the World Trade Organization (WTO), effectively enforcing the rules of the largest multilateral trade organization. On the other hand, in Japan's regional trade agreements (RTAs), none of the DSMs have ever been invoked despite the presence of …

Sources Of Ecologically Important Trait Variation In Mosquitofish (Gambusia Affinis And Gambusia Holbrooki), Heather Ann Arnett

Electronic Theses and Dissertations

The study of contemporary evolution and eco-evolutionary dynamics is classically defined in terms of genetic evolution, but the actual suite of processes driving contemporary trait change is likely much more complex than often credited. This dissertation considers additional mechanisms of trait change that might be important to an emerging model system for study of contemporary evolution and eco-evolutionary dynamics. Specifically, the research focuses on phenotypically plastic and demographic trait variation in Eastern and Western Mosquitofish (Gambusia affinis and G. holbrooki) facing the major ecological gradient of predation risk. Plasticity experiments employed a common-garden rearing design to manipulate fish …

Redefining Transitional Justice In The North American Context? The Maine Wabanaki-State Child Welfare Truth And Reconciliation Commission, Evan P. Centala

Electronic Theses and Dissertations

This thesis argues that a transformative justice discourse needs to be adopted by the current field of transitional justice in order to account for the many developments in the field. Using the case of the Maine Wabanaki-State Child Welfare Truth and Reconciliation Commission, it presents the innovative approaches and unique context the Commission operates in, following a transformative methodology to affect fundamental social change through the political, economic, and social structures that allowed the violence and harm in question to pass. Distinguishing itself from a transitional context where regime change exists with an objective to establish democracy, this thesis suggests …

The Human Dimensions Of Pollinator Conservation : Perception, Practice, And Policy In The Lowbush Blueberry Industry, Kourtney K. Collum

Electronic Theses and Dissertations

This dissertation presents comparative research of diverse agricultural actors involved in lowbush blueberry productions in Maine, USA and Prince Edward Island (PEI), Canada, in order to explore the factors that influence on-farm pollinator conservation. The research is presented through three distinct projects. In the first project, my collaborators and I ask: how do growers perceive and understand pollination in agricultural systems, and how do growers’ perceptions influence their willingness and ability to enact on-farm bee conservation? Drawing on semi-structured interviews with conventional growers, we present growers’ cultural models of pollination management and pollinator conservation. Our analysis reveals that the messages …
