Sports-related concussions are a growing public health concern affecting numerous varsity football student-athletes. This study used the social ecological model to identify intrapersonal, interpersonal, and environmental factors. The purpose of this study is to identify constraints and facilitators in academic and athletic settings for varsity football student-athletes with a sport-related concussion. Twelve current varsity football student-athletes from one institution who suffered a sport-related concussion took part in semi-structured interviews. Data were thematically analyzed. Results indicate that varsity football student-athletes with a sport-related concussion perceived numerous constraining and facilitating social ecological factors in the academic and athletic settings. Intrapersonal constraints revolved around loss of motivation, loss of social identification, stress, anxiety and depression, injury-specific issues (i.e. difficulty thinking clearly, remembering, drowsiness), internal pressure to return, while intrapersonal facilitators included prior experiences of enjoyment in academic and athletic activities, seeing improvements in the recovery process, and not giving up. Interpersonal constraints related to insufficient social support, lack of awareness and guidance on concussion knowledge, external pressure to return, and lack of academic support post-concussion, while interpersonal facilitators included passionate therapy staff, and sport psychologist. Environmental constraints pertained to return-to-play and return-to-learn protocols, while environmental facilitators included having access to concussion-based resources. Findings suggest that there remains a need to address constraining and facilitating factors in the academic and athletic settings for varsity football student-athletes with a sport-related concussion

The diffuse runoff of agricultural nutrients, also called agricultural nonpoint source pollution (NPS), is a widespread threat to freshwater resources. Despite decades of research into the processes of eutrophication and agricultural nutrient management, social, economic, and political barriers have slowed progress towards improving water quality. A critical challenge to managing agricultural NPS pollution is motivating landowners to act against their individual farm production incentives in response to distant ecological impacts. The complexity of governing the social-ecological system requires improved understanding of how policy shapes farmer behavior to improve the state of water quality. This dissertation contributes both theoretically and empirically to NPS pollution governance by examining the impacts of water quality policy design on farmer nutrient management decision making and behavior. In the first study, I theoretically contextualize the issue of agricultural NPS pollution in the broader discussion of environmental public goods dilemmas to suggest that an increased focus on the link between policy and behavior can improve sustainable resource management. I propose two empirical approaches to study the policy-behavior link in environmental public goods dilemmas: 1) explicit incorporation of social psychological and behavioral variables and 2) utilization of actor mental models, or perceptions of the world that guide decision making, to identify behavioral drivers and outcomes. In the second and third studies, I then use these approaches to examine how water quality policies for agricultural NPS collectively change farmer behavior to reduce nutrient emissions. The second chapter uses a quantitative, survey-based approach to examine the relationship between mandatory policy design and behavior change in New Zealand. I find that a shift to mandatory policy is not immediately associated with increased adoption of nutrient management practices, but the mandatory policy design is important for potential future behavior change and long-term policy support. In the third study, I combine qualitative methodology with network analysis of qualitative data to examine a spectrum of agricultural NPS pollution policies in Vermont, USA and Taupo and Rotorua, New Zealand. I use farmer mental models to examine behavior change within each of the regions, the perceived drivers of behavior change and perceived outcomes of the policy. In this study, farmers across all three regions cite mandatory water policy as a key behavioral driver, but in each region, policy design interacts with the social-ecological context to produce distinct patterns of behaviors and perceived outcomes. Taken together, this dissertation demonstrates that agricultural NPS pollution policy design must consider the interactions between policy and other social-ecological behavioral drivers in order to achieve long term water quality improvements.

Following a wildfire, land management agencies act quickly to protect ecosystem services. We don't currently understand how post-wildfire managers make trade-off decisions in these tight timelines, or if these decisions reflect current science. Using Brunson’s (2014) social-ecological systems multi-scalar model, surveys assessed manager opinions about post-wildfire projects, perceptions of stakeholder opinions, and ability or willingness to consider new science results. Public surveys asked local citizens their opinions about post-wildfire projects. Manager perceptions were measured through semi-structured phone interviews (n = 8) and a structured online survey (n = 256). Public surveys were mailed to 1,000 (971 deliverable, n = 152 usable) residents in rural and urban Great Basin and Mojave Desert ZIP codes. We found coarse- and fine-scale social and political opinions were associated with all post-wildfire management decisions, often creating perceived barriers to project implementation. Conversely, local citizens were more supportive of projects than managers perceived them to be. While the majority of managers and citizens supported the concept of incorporating experimental research, managers were less able to consider more specific research incorporation into actual projects. Ecologically, biological soil crusts (BSC) are emerging as an important fine-scale component of semi-arid restorations. However, even when BSCs are assessed prior to a restoration plan, it is unclear how or if this knowledge has any impact. BSCs were evaluated both socially and ecologically: all manager surveys contained questions specifically related to BSC, and a pilot greenhouse study assessed a) if seed drilling simulations on different stages of BSC may affect restoration plant establishment and b) if BSC excluded the invasive species Bromus tectorum. Similar to other new science results, managers were unlikely to be able/willing to consider BSC status in post-wildfire projects. However, our results suggest the possibility that, even when lightly burned, seeding strategy may influence native plant establishment. In ideal greenhouse conditions, B. tectorum was able to establish readily on both burned and unburned BSC.

Despite considerable expansion in the scope and function of the state with respect to environmental protection, the world’s biological diversity and ecosystem services continue to deteriorate. Finding ways to better govern human-nature relations in cities is an important part of addressing this decline. The aim of this thesis is to explore the potential of social-ecological resilience to inform urban governance in theory and practice, through a focus on strategic spatial planning. Resilience has become an increasingly important urban policy discourse and much hope is placed in its potential to improve urban governance. However, there is an acknowledged gap between social-ecological resilience as an ideal and the ability to govern towards it in practice. At the time this doctoral research commenced there had been no engagement with social-ecological resilience in the planning theory literature and minimal engagement by empirical planning research. It is to this gap the thesis contributes. Social-ecological resilience scholarship is found to offer planning theory a partly new way of understanding complex human-nature relations. This is relevant to calls by planning theorists for more attention to matters of substance, including ecological processes. With respect to practice, planners see potential for social-ecological resilience to critically inform strategic spatial planning, including through the framing of problems, tools for analysis/synthesis and governance options. There are also however, lessons for social-ecological resilience scholarship that emerge from the detailed empirical research which suggests that attention to the politics of the everyday activities of administrators, elected officials, planning officials, conservationists and citizens operating within the so-called ‘mangle of practice’ is critical to explaining the gap between the ideal of governing for urban resilience, and what happens in practice. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 4: Manuscript.

Children’s risk for overweight and obesity is particularly high in rural areas of the United States. Many health, psychosocial, and economic consequences are associated with childhood overweight and obesity, which concerns health researchers and professionals. But how and why might rural children be more at risk for being overweight and obese? This dissertation investigates childhood overweight and obesity in rural settings through three separate studies. First, a systematic literature review was conducted to identify determinants and mechanisms of childhood obesity-related behaviors that are specific to rural locations. The findings from the review show that lack of health resources and poverty within the rural environment may impact children’s social environment and individual factors. However, results are inconclusive and there continues to be a lack of studies focusing on linking environmental influence with individual factors. Second, a meta-analysis of current research evidence was conducted to assess the efficacy of rural interventions designed to reduce childhood overweight and obesity. Results showed that interventions have been efficacious yet modest, with a mean effect size of 0.18. Moderating variables were also examined. Mean intervention effect size was moderated by children’s age and intervention duration. Last, secondary data were used to examine the association between rural food stores and availability and affordability of fresh fruits and vegetables. A multilevel analytical approach was used to determine if rural location was associated with availability and affordability of fresh fruits and vegetables. After controlling for other variables, results showed that rural location was not associated with fruit and vegetable availability and affordability. The findings from this dissertation suggest that the area of rural childhood overweight and obesity remains understudied. More research is needed in order to understand the mechanisms of social ecological influences on diet, physical activity, and childhood overweight and obesity. This area of research, however, is rife with opportunities for public health education and promotion. Public health educators can help promote and advocate for environmental conditions that support healthy lifestyles.

Efforts to achieve urban sustainability include ecological practices within civic society. A prominent example of this is the voluntary stewardship of green urban spaces such as community gardening. People participating in these practices – so the argument goes – draw on social-ecological memory (SE-memory) – knowledge, experience, and practice of local ecosystem management. The present study scrutinises the components and implications of the concept of SE-memory. It identifies and fills a theoretical gap by investigating and adding neglected dimensions of individual memory while strengthening the concept’s social component by examining implications of SE-memory for its actual individual carriers. The study centres on Berlin’s intercultural gardens – urban community gardens where processes of SE-memory are particularly diverse. It is based on five months of fieldwork, including intensive participant observations and in-depth interviews in such gardens. The findings show that the reviving, modifying, and transmitting of SE-memory involve expressions of individuality as well as community and comprise inter-locking streams of both individual and social memory. These play a pivotal role for individuals’ sense of belonging, social inclusion, and commitment to cultural diversity central to the intercultural gardens’ contribution to social urban sustainability as they provide space for personal memory revival, allow for people to practice their culture of origin, and offer points of manifold exchange with others.

Social ecological models are recognized for allowing researchers to examine the influence of multiple factors on behaviour, yet to date relatively little research has simultaneously examined the role of personal, social, and environmental factors on youths’ physical activity, while giving consideration to the role of different types of neighbourhoods. The current study examined the physical activity of 804 youth aged 10 to 16 years residing in urban high density, suburban, or suburban low density neighbourhoods, by exploring relationships between several personal, social, and environmental factors. Findings revealed that all three factors were significant in explaining youths’ physical activity. Differences in participation were found based on gender and neighbourhood; males and youth from suburban low density neighbourhoods were significantly more physically active. Moreover, several variables were found to be important for understanding youth physical activity: sex, age, self-efficacy, encouragement, neighbourhood safety, and the use of a number of neighbourhood facilities.

Anthropogenic global changes are altering properties and functions of social and ecological systems at multiple spatial and temporal scales. In addition to climate change, the Peruvian Southern Andes has also experienced dramatic political and social change. This dissertation addresses the responses of plants, humans, communities and sub-national governments to the impacts of these changes. Methods from both the social and natural sciences were used at three levels: 1) on the forelands of the Quelccaya ice cap a chronosequence approach was used and 113 quadrats (1m2) sampled the vegetation covering an altitudinal range from 5113 to 4830 m.a.s.l.; 2) with the households of herders in the Quelcaya community surveys, interviews, participant observation, and archival research were employed; and 3) with the three Regional Governments (Arequipa, Cusco, and Puno) interviews with officials and stakeholders were conducted. The results show an upward displacement of the elevational limit of plants and a trend towards homogenization of vegetation. Warming climate, a shortened rainy season, and longer dry and cold spells are the most relevant impacts of climate change in the study area. Responses to these changes occur within households, supra-household units and communities, through dynamic institutions, traditional knowledge, and flexible polycentric social organization. These responses originate from path dependencies generated by human-environment interactions in the Peruvian Southern Andes. For instance, pastoralists increased livestock mobility within their pastures, created wetlands through irrigation, and introduced agriculture of bitter potatoes. The women agriculturalists modified the productive calendar to adjust agricultural tasks to changes in the rainfall regime; they replaced maize for wheat and fava bean, because these crops are more resistant to cold spells. Agro-pastoralists increase institutional water governance and demand infrastructure to improve efficient water use. Synergies between local and regional adaptive responses to climate change may be led by projects like building irrigation infrastructure and strengthening local resource governance, although there are also disjunctions that limit adaption. Local social ecological systems are adaptive and resilient to multi-scale social environmental disturbances by a malleable forging of former strategies to face change, innovation, polycentric social organization, and a dynamic institutional body that promptly response to change. / text

Ecological economics and its policy recommendations have become overwhelmed by economic valuation, shadow pricing, sustainability measures, and squeezing Nature into the commodity boxes of goods, services and capital in order to make it part of mainstream economic, financial and banking discourses. There are deeper concerns which touch upon the understanding of humanity in its various social, psychological, political and ethical facets. The relationship with Nature proposed by the ecological economics movement has the potential to be far reaching. However, this is not the picture portrayed by surveying the amassed body of articles from this journal or by many of those claiming affiliation. A shallow movement, allied to a business as usual politics and economy, has become dominant and imposes its preoccupation with mainstream economic concepts and values. If, instead, ecological economists choose a path deep into the world of interdisciplinary endeavour they will need to be prepared to transform themselves and society. The implications go far beyond the pragmatic use of magic numbers to convince politicians and the public that ecology still has something relevant to say in the 21st Century.
