Financing Climate Resilience: Mobilizing Resources And Incentives To Protect Boston From Climate Risks, David L. Levy, Rebecca Herst
Financing Climate Resilience: Mobilizing Resources And Incentives To Protect Boston From Climate Risks, David L. Levy, Rebecca Herst
Sustainable Solutions Lab
This report explores the challenges of financing climate-resilience investments in the Boston region. As risks from storm surge, sea level rise, and extreme weather increase, there is growing urgency for pre-disaster investments to reduce physical risk, reduce social vulnerability, and increase capacity for emergency response and disaster recovery. However, these investments face significant barriers, including market failures, capital budget constraints, and misaligned incentives. The report identifies a range of funding mechanisms appropriate at different scales, including general obligation bonds, resilience fees, property tax surcharges, stormwater fees, tax increment financing, business improvement districts, and insurance-based funding. It evaluates these mechanisms using …

College Students’ Personality Traits In Relation To Career Readiness, Shelby R. Overacker, Carly E. Kalis, Francesca Coppola
Student Publications
This study examined sixty-one Gettysburg College juniors and seniors (31 males, 30 females) to measure how the Big Five personality traits, and whether a student has Type D characteristics, determines if a student is career ready. We collected data through an in-person survey, with questions about personality traits, ambition, career readiness, and demographics. Regression was used to statistically analyze our first hypothesis. The results found that there is a significant positive association between conscientiousness and career readiness, but there is no significant association between extraversion and career readiness. For the second hypothesis, a mediation model was used. We found that …

The lack of females occupying leadership positions in the modern workplace has prompted the research of this study. In order to better understand the perceptions that exist regarding successful leadership, this study was conducted with the intention of understanding individual leadership style through the Multifactor Leadership Questionnaire, which measures transactional and transformational leadership styles (Bass and Avolio, 1993). 64 male and female participants, made up of 36 students and 28 individuals in the workforce ages 18-61 with an average age of 31 answered 21 questions to assess their leadership style and 1 to measure who they perceived as a successful …
Effectiveness Of Social Media Analytics On Detecting Service Quality Metrics In The U.S. Airline Industry, Xin Tian
Information Technology & Decision Sciences Theses & Dissertations
During the past few decades, social media has provided a number of online tools that allow people to discuss anything freely, with an increase in mobile connectivity. More and more consumers are sharing their opinions online with others. Electronic Word of Mouth (eWOM) is the virtual communication in use; it plays an important role in customers’ buying decisions. Customers can choose to complain or to compliment services or products on their social media platforms, rather than to complete the survey offered by the providers of those services. Compared with the traditional survey, or with the air travel customer report published …
Online Social Capital: Social Networking Sites' Influence On Civic And Political Engagement, Charles L. Bush
Online Social Capital: Social Networking Sites' Influence On Civic And Political Engagement, Charles L. Bush
Sociology & Criminal Justice Theses & Dissertations
This thesis examines how using social networking sites (SNS) is correlated with levels of civic and political engagement of college students at Old Dominion University. Past research has yielded mixed results on the link between online social capital and civic and political engagement. Major limitations of past research include grouping together social networking sites that are substantially different and not considering these sites’ impact on the different forms of social capital. This thesis first examines how social networking site preference, intensity of use, and motives for use factor into an individual’s online social capital. Secondly, this thesis looks at how …

Determinants Of Household Water Use In The City Of Kalamazoo, Michigan: The Role Of Climate And Socioeconomic Factors, Danielle Molenaar
Masters Theses
Located in the Great Lakes Watershed, the City of Kalamazoo can be considered “water rich”. Therefore, the area has been absent from water use studies. Water use studies are beneficial in all locations; as they can aid city planners, water resource managers, and utility companies. This study examines how household monthly water use in the City of Kalamazoo is impacted by both climate and socioeconomic variables over the period 2006-2016. Household level data were aggregated into census tracts to obtain monthly tract averages for the eleven-year period. Ordinary least squares regression (OLS) was used to determine which variables impact the …

Geography Faculty Publications and Presentations
For cities in sub-Saharan Africa a 1.5 °C increase in global temperature will bring forward the urgency of meeting basic needs in sanitation, drinking water and land-tenure, and underlying governance weaknesses. The challenges of climate sensitive management are exacerbated by rapid population growth, deep and persistent poverty, a trend for resolving risk through relocation (often forced), and emerging new risks, often multi-hazard, for example heat stroke made worse by air pollution. Orienting risk management towards a developmental agenda can help. Transition is constrained by fragmented governance, donor priorities and inadequate monitoring of hazards, vulnerability and impacts. Opportunities arise where data …

Real World, Large Scale Iot Systems For Community Eldercare: Experiences And Lessons Learned, Alvin Cerdena Valera, Wei Qi Lee, Hwee-Pink Tan, Hwee Xian Tan, Huiguang Liang
Research Collection School Of Computing and Information Systems
The paradigm of aging-in-place - where the elderly live and age in their own homes, independently and safely, with care provided by the community - is compelling, especially in societies that face both shortages in institutionalized eldercare resources, and rapidly-aging populations. When the number of elderly who live alone rises rapidly, support and care from their communities become increasingly critical. Internet-of-Things(IoT) technologies, particularly in-home monitoring solutions, are becoming mature. They can become the fundamental enabler for smart community eldercare. In this chapter, we share our real-world experiencesgleaned from an ongoing large-scale project on IoT-enabled community eldercare. We identify technology-centric challenges …

Interacting With The Trail: A Comprehensive Approach To Developing An Environmental Education Program For Agnolakely Private Nature Reserve, Claire Hamilton
Independent Study Project (ISP) Collection
Madagascar is a diverse island, biologically and geographically. This has led to the development of endemic species and high biodiversity within the landscape. Unfortunately, due to poverty, extraction of natural resources, and a growing population, these species have become threatened. Agnolakely, is a private nature reserve, located in eastern Madagascar that is trying to combat these challenges through reforestation projects and land protection. Agnolakely is not only of ecological value, but is also integral in the community structure. As Agnolakely expands it has become essential to implement education and outreach for the reserve. This study was designed to collect biological …
Ethically Sourced Vanilla: Certifications In The Production Of Vanilla In The Sava Region Of Madagascar, Maisie Campbell
Ethically Sourced Vanilla: Certifications In The Production Of Vanilla In The Sava Region Of Madagascar, Maisie Campbell
Independent Study Project (ISP) Collection
Vanilla is an orchid whose beans are harvested after ten months on the vine. About eighty percent of the world’s vanilla is produced in Madagascar and the SAVA region is the capital of vanilla production within the country. The changing demand of vanilla, damage from cyclones, and the three-year development of the vanilla plants before they begin producing beans causes a boom and bust cycle of prices of vanilla. Some organizations have tried to ameliorate the problems these cycles and low prices pose to vanilla farmers by creating certifications for companies that promise that they will not pay less than …
Exploiting User And Venue Characteristics For Fine-Grained Tweet Geolocation, Wen Haw Chong, Ee Peng Lim
Exploiting User And Venue Characteristics For Fine-Grained Tweet Geolocation, Wen Haw Chong, Ee Peng Lim
Research Collection School Of Computing and Information Systems
Which venue is a tweet posted from? We call this a fine-grained geolocation problem. Given an observed tweet, the task is to infer its discrete posting venue, e.g., a specific restaurant. This recovers the venue context and differs from prior work, which geolocats tweets to location coordinates or cities/neighborhoods. First, we conduct empirical analysis to uncover venue and user characteristics for improving geolocation. For venues, we observe spatial homophily, in which venues near each other have more similar tweet content (i.e., text representations) compared to venues further apart. For users, we observe that they are spatially focused and more likely …
Detect Rumor And Stance Jointly By Neural Multi-Task Learning, Jing Ma, Wei Gao, Kam-Fai Wong
Detect Rumor And Stance Jointly By Neural Multi-Task Learning, Jing Ma, Wei Gao, Kam-Fai Wong
Research Collection School Of Computing and Information Systems
In recent years, an unhealthy phenomenon characterized as the massive spread of fake news or unverified information (i.e., rumors) has become increasingly a daunting issue in human society. The rumors commonly originate from social media outlets, primarily microblogging platforms, being viral afterwards by the wild, willful propagation via a large number of participants. It is observed that rumorous posts often trigger versatile, mostly controversial stances among participating users. Thus, determining the stances on the posts in question can be pertinent to the successful detection of rumors, and vice versa. Existing studies, however, mainly regard rumor detection and stance classification as …
Do Voluntary Commons Associations Deliver Sustainable Grazing Outcomes? An Empirical Study Of England, Shaun Larcom, Terry Van Gevelt
Do Voluntary Commons Associations Deliver Sustainable Grazing Outcomes? An Empirical Study Of England, Shaun Larcom, Terry Van Gevelt
Research Collection College of Integrative Studies
In 1965, the Commons Registration Act came into force in England and Wales. The Act led to the removal of the capacity of commoners to regulate the intensity of grazing via traditional legal means. From this policy shock a number of voluntary commons associations were formed. These voluntary groups relied on their members to agree upon how the commons should be managed. Using two-stage least squares regression analysis we find that commons governed by these associations are much more likely to produce sustainable grazing outcomes. These results are robust to the existence of a variety of controls, including overlapping institutional …
Throw Me A Lifeline: A Comparison Of Port Cities With Antithetical Adaptation Strategies To Sea-Level Rise, Claudia Marie Risner
Throw Me A Lifeline: A Comparison Of Port Cities With Antithetical Adaptation Strategies To Sea-Level Rise, Claudia Marie Risner
Graduate Program in International Studies Theses & Dissertations
Sea-level rise (SLR) is a manifestation of climate change that is particularly hazardous to port cities that must remain on the waterfront to function, yet are increasingly battered and flooded by encroaching storms, and sinking into the rising saltwater. Despite sharing a common high level of risk, port cities are choosing antithetical adaptation strategies that range from hard-engineered structural flood protection, to behavioral modifications, to innovative soft-engineered measures, to doing nothing at all. Why is this? Are transnational city networks, such as C40 Cities, a lifeline to drowning cities? Do differences in governance structure, financial capacity, risk tolerance to the …

When The Wind Blows: An Evaluation Of Key Factors That Enabled The Proliferation Of Wind Energy Generation In The United States Through 2016, Mary Sodini Bell
Graduate Program in International Studies Theses & Dissertations
Increasing CO2 emissions have led to extreme weather phenomena labeled as climate change. Energy consumption and the burning of fossil fuels are primary contributors to climate change, which necessitates finding ways to decrease fossil fuel consumption critical to preserving the planet while helping nations reduce dependence on costly fossil fuels. Renewable energy is one part of the solution to reducing CO2 emissions. Wind energy is the fastest growing form of renewable energy across the world and within the U.S., but the key factors that enabled the U.S. wind industry to grow from zero installed capacity at the beginning …

Effects Of Beaver Dams On Urban Stream Hydraulic Response During Storm Events, Erin Poor
Effects Of Beaver Dams On Urban Stream Hydraulic Response During Storm Events, Erin Poor
Environmental Science and Management Professional Master's Project Reports
Urbanization of landscapes alters watershed hydrology, leading to changes in the natural flow regime of local streams. Runoff from impervious surfaces and routing of stormwater can cause a rapid increase in the volume and velocity of streamflow. This is observed in the hydrograph as a steep rising limb, followed by a high peak, and a rapid falling limb. This rapidly varying streamflow, often referred to as flashiness, can increase erosive forces on the channel bed and banks, leading to channel incision and bank erosion. In areas where the hydrologic regime is less impacted by humans, beaver dams and ponds attenuate …

Analyzing The Efficiency Of Reforestation Efforts In Regaining Carbon Storage In A Costa Rican Cloud Forest, Elvin Irihamye
Analyzing The Efficiency Of Reforestation Efforts In Regaining Carbon Storage In A Costa Rican Cloud Forest, Elvin Irihamye
Student Research Conference Select Presentations
Forests hold an important place in offsetting carbon emissions, absorbing nearly 40 percent of man-made fossil fuel emissions every year. Over the last 100 years, the effects of deforestation have crippled our forest’s ability to store excess carbon, leading to drastic atmospheric change. Efforts to regrow deforested forests have increased rapidly to address issues like climate change. There is thus a need to analyze current efforts at regaining carbon storage, a critical component to maintaining atmospheric homeostasis. Accordingly, we traveled to the Cloudbridge Nature Reserve in San Gerardo, Costa Rica to aggregate data on the carbon storage capabilities across three …
Remote Sensing And Spatial Metrics For Quantifying Seagrass Landscape Changes: A Study On The 2011 Indian River Lagoon Florida Seagrass Die-Off Event, René Dieter Baumstark
Remote Sensing And Spatial Metrics For Quantifying Seagrass Landscape Changes: A Study On The 2011 Indian River Lagoon Florida Seagrass Die-Off Event, René Dieter Baumstark
USF Tampa Graduate Theses and Dissertations
Florida’s seagrasses are ecologically important marine environments which have suffered major degradation caused by increasing anthropogenic pressures. A 2011 seagrass die-off event caused by an algal bloom in the Florida Indian River Lagoon (IRL) was particularly severe with a majority of seagrass lost in areas such as the Banana River. An understanding of how this coastal marine environment changed is an important step toward better managing resources for conservation. Modern tools and methods provide new opportunities to study these changes at the landscape scale, a scale that informs on the larger more comprehensive state of a system. Classified satellite imagery …
Rain Rituals As A Barometer Of Vulnerability In An Uncertain Climate, L. Jen Shaffer
Rain Rituals As A Barometer Of Vulnerability In An Uncertain Climate, L. Jen Shaffer
Journal of Ecological Anthropology
Researchers and aid agencies, seeking to improve their understanding of local climate change responses, adaptation, and vulnerability, frequently interact with communities around the world who strongly emphasize their religious beliefs and practices. Dismissal and misunderstandings of these local perspectives can slow assessments of local climate vulnerability and development of adaptive capacity. In this paper, I show how analysis of rain ritual failure exposes the multiple stressors Ronga communities in southern Mozambique face, and as such, serves as a proxy measure for climate vulnerability at the local level. Oral histories and targeted interviews with participating elders, local chiefs, and community members …

Environmental Studies Faculty Publications
This study is a quantitative analysis of cirques in three regions of Iceland: Tröllaskagi, the East Fjords and Vestfirðir. Using Google Earth and the National Land Survey of Iceland Map Viewer, we identified 347 new cirques on Tröllaskagi and the East Fjords region, and combined these data with 100 cirques previously identified on Vestfirðir. We used ArcGIS to measure length, width, aspect, latitude and distance to coastline of each cirque. Palaeo‐equilibrium‐line altitudes (palaeo‐ELAs) of palaeo‐cirque glaciers were calculated using the altitude‐ratio method, cirque‐floor method and minimum‐point method. The mean palaeo‐ELA values in Tröllaskagi, the East Fjords and Vestfirðir are 788, …

Optimization Of Geosynchronous Space Situational Awareness Architectures Using Parallel Computation, Michael S. Felten
Theses and Dissertations
Improving Space Situational Awareness (SSA) remains one of the DoD’s top priorities. Current research at the Air Force Institute of Technology (AFIT) has shown that modeling and simulation of Geosynchronous Earth Orbit (GEO) SSA architectures can identify optimal combinations of ground and space-based sensors. This thesis extends previous research by expanding design boundaries and refining the methodology. A genetic algorithm examined this increased trade space containing 1022 possible architectures. Experimental trials that would have taken over 100 years on a desktop computer were completed in weeks using a high-performance computer containing over 125,000 cores. The results of the optimizer clearly …
