This thesis aimed to improve decision-maker access to economic information by testing a pricejusting methodology to annually update expenditure information for economic impacts analyses and by conducting a trends analysis of economic sector contributions to a regional economy. A secondary data analysis of historical angler survey data generated expenditure profiles adjusted over time using price indices. A replication survey was conducted to compare expenditures. Grouping anglers by trip type (one-day/multiple-day) resulted in expenditure profiles that were generally consistent over time as anglers spent approximately $75 and $130 on one-day and multiple-day trips, respectively. These expenditures resulted in total economic impacts of over $13 million. A series of automatic social accounting matrices (ASAM) were then employed to execute economic base analyses, quantifying the role of sectors in the regional economy. The tourism sector consistently contributed over 20% of gross employment and almost 10% of gross output over time.

The existing research in the field of tourism has exhibited a clearer understanding of how residents perceive the dynamic and complex phenomena of tourism. Since the goals of tourism planning and development are to seek maximization of benefits and minimization of the costs of tourism, it is apparent that the effective evaluation of tourism impacts will be valuable information in successful strategies for tourism product development and operation. With these perspectives, this study attempted to investigate the underlying dimensions explaining residents' perceived tourism impacts and to identify relationships between determinants and residents' perceived tourism impacts. The social exchange theory provided a fundamental framework for this study. The dimensions of the tourism impacts were addressed by explicating economic, social/cultural, environmental/physical impacts of tourism development from literature review. Ten determinants which affect residents' perception were identified from past research on tourism impacts: birthplace, length of residency, community attachment, tourism related jobs, recreational activity, tourist contacts, tourism policy participation, travel experience, levels of tourism development, and growth of community. Norfolk/Virginia Beach/Newport News MSAs areas were selected as the study area because these areas provide fine multifaceted tourism attractions, generates many tourists, and influences the host community' life. A total of 316 useful respondents (13.2%) were analyzed by using the SPSS program. Two research questions were proposed. Factor analysis, multiple regression analysis, and multivariate analysis of variance (MANAOVA) were performed. From the findings of this study, residents perceived the impacts of tourism as five different dimensions embodying economic benefits, social costs, cultural enrichment, environmental deterioration, and physical enhancement. Their perceptions were affected by eight out of ten determinants. Generally, a higher level of tourism development and growth of community affects residents' perceptions of tourism impacts. Residents who were natives, who have higher community attachment, and who had been living in the research area for a shorter time period had more concerns about the perceived impacts of tourism. In addition, perceived tourism impacts were significantly differed across household incomes and ethnic groups. For future study, it is suggested that a further investigation of determinants affecting residents' perceptions is needed for better understanding and explanation of the impacts of tourism. It is believed that this study would help tourism planners and developers formulate and implement better strategies. / Master of Science

No / This paper engages with policy on meeting development goals for water through interventions, which promote good governance. Addressing an under-researched area, we propose a new analytical framework for understanding water governance, not as a set of abstract principles, but as interlinked processes with variable practical outcomes for poor people. The framework is informed by theories of governance, institutions and structuration, empirical research and field insights. We apply the framework to a case in south-western Tanzania, and we identify a range of issues for further research, particularly relating to water access for the poor.

More than 19 million children participate in youth baseball and softball annually. Although baseball and softball are not commonly depicted as contact sports in the, according to the U.S. CPSC baseball and softball were responsible for 11.6% of all head injuries treated in emergency rooms in 2009; third most behind only cycling and football. Ball impact has been identified as the leading cause of injury in baseball and softball, with the most frequent injury resulting from a ball impacting the head. Reduced injury factor balls, infield softball masks, batter's helmets, and catcher's masks have all been integrated into baseball and softball as a means for preventing serious head injury from ball impact. The research in this thesis had four objectives: to compare the responses of the Hybrid III and NOCSAE headforms during high velocity projectile impacts, to compare head injury risk across a range of baseball stiffness designed for different age groups, to evaluate the effectiveness of infielder softball masks' ability to attenuate facial fracture risk, and to describe a novel methodology to evaluate the performance of batter's helmets and catcher's masks. Results of these research objectives determined the most suitable ATD headform to evaluate head injury risk for high velocity projectile impacts, provided a framework for determining the optimal age-specific ball stiffness and optimal infield mask design, and disseminated STAR ratings for batter's helmets and catcher's masks to the public. The research presented in this thesis can be used to further improve safety in baseball and softball. / MS

The goals of this study were to measure the ability of catcher's masks to attenuate head accelerations upon impact with a baseball, and to compare these head accelerations to established injury thresholds for concussions. Testing involved using a pneumatic cannon to shoot baseballs at an instrumented (3-2-2-2 accelerometer array) Hybrid III headform (a 50th percentile male head and neck) with and without a catcher's mask on the head. The ball speed was controlled from approximately 26.8 – 35.8 m/s (60 – 80 mph) and regulation NCAA baseballs were used. Peak linear resultant acceleration was 140 – 180 g without a mask and 16 – 30 g with a mask over the range of balls speeds investigated. Peak angular resultant acceleration was 19500 – 25700 rad/sec2 without a mask and 2250 – 3230 rad/sec2 with a mask. The Head Injury Criterion was 93 – 181 without a mask and 3 – 13 with a mask and the Severity index was 110 – 210 without a mask and 3 – 15 with a mask. Catcher's masks reduced head acceleration metrics by approximately 85% when baseballs were impacted with just the headform. Head accelerations with a catcher's mask were substantially lower than contemporary injury thresholds, yet evidence indicates that baseball impacts to the mask still result in concussions. / Master of Science

This thesis contains two studies that explore different methods of visitor management in recreation. The management strategies studied here are both relatively indirect approaches intended to minimize the environmental and social impacts that visitors cause in protected areas. The Annapolis Rocks study focuses on visitors' evaluations of a site management strategy that shifted camping from a flat, open area to constructed side-hill campsites. A visitor questionnaire was administered before and after the treatment to determine visitors' ratings of importance and satisfaction for various campsite attributes. We found some evidence of visitor displacement but concluded that the site management strategy supported the intentions of the managers. The Leave No Trace study evaluates the effectiveness of the Trainer courses in improving the knowledge, ethics, and behavior of the participants and encouraging them to teach others in the community. This study employed pre-course, post-course, and follow-up questionnaires to evaluate the participants' short-term and long-term gains from the course. Trainer course participants showed significant short-term and long-term gains from the course, with a slight decline in the total gain four months after the course. The participants showed improvements in low-impact behaviors, suggesting that education is an effective visitor management strategy. These studies demonstrate that managers can be successful at controlling visitor impacts without relying on stringent regulations and enforcement. / Master of Science

The coastal section of the London to Penzance railway line (Dawlish-Teignmouth) lies very close to sea level and has been susceptible to frequent closure during high seas and storm events. As the main railway connection for the southwest of England to the rest of Great Britain, it is a vital transport link for the Devon and Cornwall economy. Current understanding of future sea-level rise in the region is compromised by a lack of reliable geological data on which to establish accurate future sea-level projections. Furthermore, the impacts – in engineering and economic terms – of potential sea-level change on the long-term functioning of the main railway are unclear, and future policy making and planning are compromised by a similar gap in scientific knowledge. The central aim of this thesis is to establish the extent to which future sea-level changes will impact upon the Southwest’s main railway line. This aim carries three objectives: (1) to establish accurate sea-level trends over the last 4000 years (late Holocene) in order to validate geophysical models used in current future sea-level projections in the southwest of England; (2) to establish the likely impacts of future sea-level change on the functioning of the Dawlish-Teignmouth railway line; and (3) to integrate climate and socio-economic futures (scenarios) in an internally consistent manner for future use in regional policy debates. In addressing these objectives, we estimate that during the last 2000 years the coast of south Devon has subsided at a rate of ~1.1 mm/yr, generating a relative sea-level rise of ~0.9 mm/yr. The geophysical model (used to determine regional sea-level projections) underestimates the geologically estimated coastal subsidence rate by only 17%, which would generate an additional sea-level rise, compared to predicted values, of 0.014 m by 2100. Based on an empirical trend between increases in sea-level changes and rail functioning during the last 40 years, the corrected sea-level projections provide input for establishing future days with line restrictions due to overtopping on the Southwest Mainline. Impacts to both the Southwest economy (e.g., rail users) and the infrastructure owners have been determined, and integrating these forecasts with socio-economic scenarios (SES) has highlighted the important interaction between climate and socio-economic trends and future vulnerability. In a worst case scenario (e.g., high emissions), rail services are predicted to be disrupted (on average) for around 35% of the winter by 2060. By this stage, the cost of these disruptions will have exceeded the capital needed for constructing a new alternative inland route.
