    Arnold, Amy; Lindsey, Andrew; McCoy, Andrew P.; Khademian, Anne M.; Lockee, Barbara B.; Adams, Carol; Amelink, Catherine T.; Blankenship, Chip; Glover, Christopher; Harris, Chrystal; Hoyle, Clayton; Potts, Colin; Pike, Dale; Whittaker, Dale; Kjellsson, Daniel; Hare, David; Tegarden, David P.; Tinapple, David; Ucko, David; Nahapetian, Eta; Hou, Feng; Holmes, Glen A.; Keyel, Jared; Garrett, Jeff; Joo, Jenna; McPhee, Joel; Boyer, John D.; Flato, John; Lister, Jonothan; Haldane, Joseph; Greenwood, Julie; Sanders, Karen Eley; Bruce, Karla; Lindsey, Kate; Carlson, Kimberly; Wingfeld, Kristin; Hamilton, Laura; McNair, Lisa D.; Kamlet, Mark; Semmel, Marsha; Holt, Matthew; Richey, Michael; Kumar, Mukul; Spivy, Nene; Cardwell, Owen; Holloway, Rachel L.; Swearer, Randy; Hall, Ralph P.; Clark-Stallkamp, Rebecca; Mazer, Robert; Smith, Robert; Reynolds, Roger; Bess, Diego Scott; Weimer, Scott; Sagheb, Shahabedin; Garmise, Sheri; Ashburn, Sherrell; Johnson, Sylvester; Cardone, Taran; Nicewonger, Todd; Martin, Tom; Quick, Tom; Rikakis, Thanassis; Skuzinski, Thomas; Contomanolis, Manny (Calhoun Center for Higher Education Innovation, 2020-08-24)
    This report addresses the globalized knowledge economy in the 21st century; not only as it exists today, but the knowledge economy needed to meet the demands of tomorrow. This report proposes that in order for our knowledge economy to grow and be sustainable, it must be inclusive in ways that enable it to adapt to—and incorporate within it—the personal and professional growth of a large and diverse body of lifelong learners. In this introduction, we first define what we mean by inclusive knowledge and explain how our proposed definition expands some of the traditional understandings. We then show that an expansive and dynamic conceptualization of knowledge increases inclusion and promotes lifelong adaptive learning as a mindset and a practice.

    Addressing Inequality: The First Step Beyond COVID-19 and Towards Sustainability
    Ashford, Nicholas A.; Hall, Ralph P.; Arango-Quiroga, Johan; Metaxas, Kyriakos A.; Showalter, Amy L. (MDPI, 2020-07-03)
    The COVID-19 pandemic has impacted billions of lives across the world and has revealed and worsened the social and economic inequalities that have emerged over the past several decades. As governments consider public health and economic strategies to respond to the crisis, it is critical they also address the weaknesses of their economic and social systems that inhibited their ability to respond comprehensively to the pandemic. These same weaknesses have also undermined efforts to advance equality and sustainability. This paper explores over 30 interventions across the following nine categories of change that hold the potential to address inequality, provide all citizens with access to essential goods and services, and advance progress towards sustainability: (1) Income and wealth transfers to facilitate an equitable increase in purchasing power/disposable income; (2) broadening worker and citizen ownership of the means of production and supply of services, allowing corporate profit-taking to be more equitably distributed; (3) changes in the supply of essential goods and services for more citizens; (4) changes in the demand for more sustainable goods and services desired by people; (5) stabilizing and securing employment and the workforce; (6) reducing the disproportionate power of corporations and the very wealthy on the market and political system through the expansion and enforcement of antitrust law such that the dominance of a few firms in critical sectors no longer prevails; (7) government provision of essential goods and services such as education, healthcare, housing, food, and mobility; (8) a reallocation of government spending between military operations and domestic social needs; and (9) suspending or restructuring debt from emerging and developing countries. Any interventions that focus on growing the economy must also be accompanied by those that offset the resulting compromises to health, safety, and the environment from increasing unsustainable consumption. This paper compares and identifies the interventions that should be considered as an important foundational first step in moving beyond the COVID-19 pandemic and towards sustainability. In this regard, it provides a comprehensive set of strategies that could advance progress towards a component of Sustainable Development Goal (SDG) 10 to reduce inequality within countries. However, the candidate interventions are also contrasted with all 17 SDGs to reveal potential problem areas/tradeoffs that may need careful attention.

Jack; Dunay, Robert J.; King, Nathan T.; Muelenaer, Andre A.; Muelenaer, Penelope; Rist, Cassidy; Wenzel, Sophie (Virginia Tech, 2017-05-15)
    The vision for this project has emerged from several years of research, teaching, and service in Africa and holds the potential to internationalize education at Virginia Tech and in our partner institutions in Malawi. The vision is simple, to develop a state-of-the-art, data rich, virtual decision-support and learning environment that enables local-, regional-, and national-level actors in developed and developing regions to make decisions that improve resilience and sustainability. Achieving these objectives will require a system that can combine biogeophysical and sociocultural data in a way that enables actors to understand and leverage these data to enhance decision-making at various levels. The project will begin by focusing on water, agricultural, and health systems in Malawi, and can be expanded over time to include any sector or system in any country. The core ideas are inherently scalable...

    Antimicrobial Resistance Mitigation [ARM] Concept Paper
    Vikesland, Peter J.; Alexander, Kathleen A.; Badgley, Brian D.; Krometis, Leigh-Anne H.; Knowlton, Katharine F.; Gohlke, Julia M.; Hall, Ralph P.; Hawley, Dana M.; Heath, Lenwood S.; Hession, W. Cully; Hull, Robert Bruce IV; Moeltner, Klaus; Ponder, Monica A.; Pruden, Amy; Schoenholtz, Stephen H.; Wu, Xiaowei; Xia, Kang; Zhang, Liqing (Virginia Tech, 2017-05-15)
    The development of viable solutions to the global threat of antimicrobial resistance requires a transdisciplinary approach that simultaneously considers the clinical, biological, social, economic, and environmental drivers responsible for this emerging threat. The vision of the Antimicrobial Resistance Mitigation (ARM) group is to build upon and leverage the present strengths of Virginia Tech in ARM research and education using a multifaceted systems approach. Such a framework will empower our group to recognize the interconnectedness and interdependent nature of this threat and enable the delineation, development, and testing of resilient approaches for its mitigation. We seek to develop innovative and sustainable approaches that radically advance detection, characterization, and prevention of antimicrobial resistance emergence and dissemination in human-dominated and natural settings...

    Applying Pavement Life Cycle Assessment Results to Enhance Sustainable Pavement Management Decision Making
    Bryce, James Matthew (Virginia Tech, 2014-06-27)
    Sustainable pavement management implies maintaining acceptable condition of pavements while also considering the tradeoff between cost, environmental impacts and social impacts of pavement investments. Typical pavement management practices only consider economic considerations, and environmental mitigation techniques are employed after the selection of the maintenance action is complete. This dissertation presents a series of papers that demonstrate the impact of decision making on the environmental impact of the pavements both at the project and network levels of pavement management. An analysis was conducted of two models that relate pavement properties to vehicle rolling resistance and fuel consumption. These models were used, along with other tools to evaluate the impact of including the use phase of a pavement into pavement lifecycle assessments. A detailed project level lifecycle assessment was conducted, and it was found that the vehicles on the pavement during the use phase contribute the most to environmental pollutants by a significant margin over other phases of the lifecycle. Thus, relatively small improvements in the factors which contribute to rolling resistance may significantly influence the environmental impacts of the pavement. Building on this, a network level lifecycle assessment method was proposed to probabilistically quantify energy consumption for a given set of expected maintenance actions. It was shown that, although maintenance actions require a certain amount of energy consumption, this energy can be offset by improved road conditions leading to reduced rolling resistance. However, this tradeoff of reduced energy consumption also includes increased costs for a given network condition. In other words, the lowest energy consumption values did not tend to fall along the line defined by minimizing the cost divided by the pavement condition. In order to demonstrate how this tradeoff should be addressed, a novel decision analysis framework was developed, and implemented on a specific pavement network. Finally, a survey of transportation professionals was evaluated to determine their optimal points within the solution space defined by minimizing costs and energy consumption while maximizing pavement condition. It was found that the solution space could be greatly reduced by implementing their responses using the proposed decision analysis framework.

    Assessing Sustainability in Rural Water Supply Systems in Developing Countries Using a Novel Tool Based on Multi-Criteria Analysis
    Domínguez, Isabel; Oviedo-Ocaña, Edgar Ricardo; Hurtado, Karen; Barón, Andrés; Hall, Ralph P. (MDPI, 2019-09-27)
    Rural water supply systems (RWSS) in developing countries typically have deficiencies that threaten their sustainability. This research used Multi-Criteria Analysis and the Analytical Hierarchy Process to identify indicators that can be used to assess the sustainability of RWSS. The assessment tool developed is composed of 17 attributes with 95 quantifiable indicators. The tool enables the assessment of the sustainability of RWSS, using data collected through semi-structured interviews, social cartography, technical inspection, household surveys, and water monitoring. The tool was applied in a case study of a RWSS in the Andean region of Colombia, illustrating a participatory, holistic, and structured assessment that provided a single sustainability measure for the system (3.0/5.0). The tool’s completeness is represented by its extensive attributes and indicators that deliver a robust baseline on the state of a system, help identify improvement strategies, and monitor system performance over time that can assists rural community organizations with RWSS management.

    Assessing the Performance of Public-Private Partnership Highway Projects: From Anecdotes to Comprehensive Evidence
    Ahmed, Manik (Virginia Tech, 2021-07-02)
    Over roughly the last three decades, governments worldwide have implemented public private partnerships (P3s) to mobilize both private funds and public resources to develop transportation infrastructure, which has provided private entities contemporary opportunities to design, finance, construct, operate and maintain these important assets. Typically, P3s are large and complex undertakings that involve and impact many stakeholders, including public officials, financiers, builders, business owners and taxpaying citizens. Consequently, their efficacy depends – to a great extent – on how well they meet the interests of this array of stakeholders. Hence, effective assessment of P3s is crucial to determine whether these infrastructure initiatives and project outcomes satisfy these stakeholders' interests throughout a P3's life-cycle. Researchers and practitioners have considered various aspects of P3s when considering their performance. In general, the current research landscape related to P3 performance includes two major areas: (1) the identification and implementation of critical success factors (CSFs) and key performance indicators (KPIs), and (2) the development of frameworks that conceptualize approaches to measure P3 performance. Numerous studies have focused on CSFs that are the "ingredients" of effective P3s. More recent studies have emphasized KPIs that are metrics to assess them. Alternatively, some research has taken a life-cycle approach to propose approaches for P3 evaluation that are more comprehensive than assessments of P3 delivery time and cost. While this research has produced useful insights, limited emphasis has been placed on assessing P3 performance comprehensively and beyond the public and private sector dichotomy. Therefore, this research develops a framework that identifies and assesses key stakeholder interests in P3s as a means to characterize their performance. Subsequently, this framework was employed in a case study of four P3 projects to evaluate how well these cases met stakeholder expectations and ultimately performed. The research to develop the framework and conduct the case study was organized in three integrated studies. The first study employed a systematic literature review of CSFs and KPIs where the extant literature remains largely segmented and fragmented. Synthesis of the literature helped to identify and characterize various CSFs and KPIs and their current employment within the P3 performance domain. This led to the development of a CSF-KPI framework that integrates these factors and indicators throughout a P3 project's lifecycle. The outcome of the first study served as the foundation for the second study where the framework to assess stakeholders' interests was constructed. In this process, the second study followed a systematic approach by integrating key components to assess performance. The development process involved several key steps: (1) identification of the key stakeholders – specifically the state (elected bodies and executive agencies), investors (equity providers), producers (project service providers) and users/citizens (individuals or groups impacted by a project); (2) characterization of their principal interests; (3) selection of indicators of these interests; (4) linkage of the indicators with 11 performance dimensions ranging from project environment to revenue and operations; and (5) connection of the performance dimensions with four levels of performance: planning, project management, business, and future potential. The framework was demonstrated and substantiated using data from the I-495 Capital Beltway Express project. The application confirmed the replicability of the framework. The final study utilized the framework to evaluate P3s effectiveness in serving stakeholders goals and objectives. A multiple case study was conducted of four P3 highway projects in the United States: I-495 Capital Beltway Express, LBJ Expressway, SR 125 (South Bay Expressway), and SH 130 (5and6) to examine the extent that state, investor, producer, and user/citizen interests were fulfilled. Overall, I-495 and LBJ Expressway met stakeholder interests more effectively than SR 125 and SH 130 (5and6); these two cases had stronger planning, project management, and business performance. Notably, the I-495 case was an unsolicited (or market lead) proposal that followed a collaborative planning process to shape and define the project to meet mutual interests while the LBJ Expressway case utilized a competitive best-value procurement to generate an innovative technical solution that reduced the project's cost and footprint. Whereas SR 125 and SH 130 (5and6) experienced various issues that led to their bankruptcy; the new owners of both projects have taken steps to improve their outlook. Overall, the research deepens understanding of the factors that impact stakeholder interests and their expectations of P3s, presents a holistic framework for P3 assessments, and provides evidence of how well multiple P3s performed, moving beyond conceptual frameworks that are currently found in the literature.

    Assessment of the Jones Act Waiver Process on Freight Transportation Networks Experiencing Disruption
    Fialkoff, Marc Richard (Virginia Tech, 2017-10-27)
    In October 2012, Hurricane Sandy caused massive disruption and destruction to the Mid-Atlantic region of the United States. The intensity of the storm forced the Port of New York and New Jersey to close, forcing cargo diversion to the Port of Norfolk in Virginia. Because of the Jones Act restriction on foreign vessels moving between U.S. ports, the restriction on short sea shipping was viewed as a barrier to recovery. Much of the critical infrastructure resilience and security literature focuses on the "hardening" of physical infrastructure, but not the relationship between law, policy, and critical infrastructure. Traditional views of transportation systems do not adequately address questions of governance and behaviors that contribute to resilience. In contrast, recent development of a System of Systems framework provides a conceptual framework to study the relationship of law and policy systems to the transportation systems they govern. Applying a System of Systems framework, this research analyzed the effect of relaxing the Jones Act on freight transportation networks experiencing a disruptive event. Using WebTRAGIS (Transportation Routing Analysis GIS), the results of the research demonstrate that relaxing the Jones Act had a marginal reduction on highway truck traffic and no change in rail traffic volume in the aftermath of a disruption. The research also analyzed the Jones Act waiver process and the barriers posed by the legal process involved in administration and review for Jones Act waivers. Recommendations on improving the waiver process include greater agency coordination and formal rulemaking to ensure certainty with the waiver process. This research is the first in studying the impact of the Jones Act on a multimodal freight transportation network. Likewise, the use of the System of Systems framework to conceptualize the law and a critical infrastructure system such as transportation provides future opportunities for studying different sets of laws and policies on infrastructure. This research externalizes law and policy systems from the transportation systems they govern. This can provide policymakers and planners with an opportunity to understand the impact of law and policy on the infrastructure systems they govern.

    Benefits, Burdens, Perceptions, and Planning: Developing a New Environmental Justice Assessment Toolkit for Long Range Transportation Plans
    Homer, Allison Kathleen (Virginia Tech, 2016-10-24)
    This research presents a new environmental justice assessment toolkit, the Equitable Environmental Justice Assessment Toolkit 2016 (EEJAT 2016). The purpose of this toolkit is to enable urban planners to more effectively measure whether environmental justice populations (low-income, non-white, Limited English proficiency, disabled, or elderly persons) are disproportionately burdened by long-range transportation plans. This toolkit is based on the concept that effective assessment of environmental justice (EJ) in transportation planning requires assessment frameworks that methodologically unify three sometimes divergent interests: those of federal and state bodies enforcing EJ assessment requirements, those of metropolitan planners who face capacity constraints and need guidance on how to conduct these assessments, and, most importantly, those of the protected populations themselves. This thesis involved analysis of current requirements, exploration of existing environmental justice assessment tools, case studies, decision theory, and principles of equity, and stakeholder engagement through surveys, interviews, and public meetings, all towards the development of the toolkit designed for the Roanoke Valley Transportation Planning Organization (RVTPO)'s Constrained Long-range Multimodal Transportation Plan 2040 (CLRMTP 2040) released in 2016. The resulting toolkit is a multi-step framework. The first step is a GIS map-based EJ Index, structured by normalized population distributions for each EJ demographic, and mapped by block group compared to regional (MPO) averages. This z-score based mapping was done in lieu of Roanoke's former linear model in effort to more systematically compare effects, and to more accurately represent the data, and by extension, the people. Second, the Community Profile expands upon the EJ Index to include documentation of community elements and social and economic systematic injustices in the area. Next, a Benefits and Burdens matrix guides planners to an appropriate model or method of assessment for each EJ effect for the project at hand, based on project scale and type, data availability, and skillsets of the assessor. The results of these assessments of each EJ effect are compiled for an overall Project Impact Assessment. Checks on assessor bias based on stakeholder feedback and decision theory are incorporated into this Project Impact Assessment. Cumulatively, the toolkit is designed to incorporate equity as a defining element of both processes and outcomes, to be flexible in order to be applicable to multiple projects, and to be usable by practitioners.

    Building Governance Capacity in Rural Niger: A Study of Decentralization and Good Governance Policy as Experienced in a Local Village
    Lyon-Hill, Sarah (Virginia Tech, 2012-05-10)
    Niger, a northwest African country with several systemic barriers to development, has made education a priority. In an effort to improve the national education system, Niger has implemented a decentralization program. This study examines the perceptions of local school actors concerning this decentralization policy, which prescribes improving access and quality to education and strengthening institutional capacity. Local interviews and an analysis of relevant policy documents reveal limited policy implementation at the local level accompanied by a lack of state capacity, accountability and responsiveness to local school needs. Moreover, interviewees perceive a decline in education quality due to these reforms. While policy review documents focus on building institutional capacity at the central and regional government levels, the locality examined has responded as best it can to the needs of its schools. These local efforts are hampered by few resources, limited capacity and understanding of the importance of education by citizens, as well as a mistrust in government institutions, including schools, among local community members. Community leadership, development of participatory public space and trust building, could improve local education capacity to a certain extent, however, strong central government that provides additional resources and builds the capacities of school staff is necessary.

    Buying to Thrive: Exploring the Potential for Market-Based Approaches to Contribute to Increases in Diet Diversity in Mozambique
    Agnew, Jessica L. (Virginia Tech, 2020-08-04)
    Globally, more than two billion people suffer from deficiencies in micronutrients that are essential for human health. Low-income populations in low- and middle-income countries are especially vulnerable to these deficiencies. There are three priority interventions used to reduce micronutrient deficiencies and improve overall nutrition status — supplementation, fortification, and diet diversity. As the share of food purchases made by low-income households has been increasing, there is increasing interest in the role the private sector can play in these interventions. Currently, there is little known about the potential for a market-based approach to contribute to improvements in diet diversity. Proven to be one of the most effective ways of improving nutritional status, increasing diet diversification among low-income populations will be essential for reducing micronutrient deficiencies in the long-term. The purpose of this research is to contribute evidence on the potential for a market-based approach to increase diet diversity among low-income households in Mozambique. This research starts by examining the extent to which low-income consumers in Nampula, Mozambique make diverse food purchases and the amount they are willing to pay for such diversity. Since diet diversification is intended to improve health, the connections between individual-level health constructs and diversity of food purchases is subsequently investigated. These studies are then used as the basis for a participatory community-based intervention that explores if health constructs influence modifications in food purchases and the barriers and enabling factors that exist to using the market to increase household diet diversity. The findings of this work reveal that there is potential for markets to contribute to the diversity of foods consumed by low-income households; however, concerted efforts between the private, public, and civil sectors will likely be required for the success and longevity of market-based approaches.

    Characterization and Assessment of Transportation Diversity: Impacts on Mobility and Resilience Planning in Urban Communities
    Rahimi Golkhandan, Armin (Virginia Tech, 2020-06-25)
    A transportation system is a critical infrastructure that is key for mobility in any community. Natural hazards can cause failure in transportation infrastructure and impede its routine performance. Ecological systems are resilient systems that are very similar to transportation systems. Diversity is a fundamental factor in ecological resilience, and it is recognized as an important property of transportation resilience. However, quantifying transportation diversity remains challenging, which makes it difficult to understand the influence of diversity on transportation performance and resilience. Consequently, three studies are undertaken to remedy this circumstance. The first study develops a novel approach – inspired by biodiversity in ecological stability theory – to characterize and measure transportation diversity by its richness (availability) and evenness (distribution). This transportation diversity approach is then applied to New York City (NYC) at the zip code level using the GIS data of transportation modes. The results demonstrate the variation of transportation diversity across the city. The characterized inherent and augmented complementarities start to uncover the dynamics of modal compensation and to demonstrate how transportation diversity contributes to this phenomenon. Moreover, the NYC zip codes with low transportation diversity are mainly in hurricane evacuation zones that are more vulnerable. Consequently, low transportation diversity in these areas could affect their post-disaster mobility. In the second study, the influence of transportation diversity on post-disaster mobility is examined by investigating the patterns of mobility in New York City one month before and after Hurricane Sandy using Twitter data. To characterize pre- and post-Sandy mobility patterns, the locations that individuals visited frequently were identified and travel distance, the radius of gyration, and mobility entropy were measured. Individuals were grouped according to the transportation diversity of their frequently visited locations. The findings reveal that individuals that lived in or visited zip codes with higher transportation diversity mostly experienced less disturbance in their mobility patterns after Sandy and the recovery of their mobility patterns was faster. The results confirm that transportation diversity affects the resilience of individual post-disaster mobility. The approach used in this study is one of the first to examine the root causes of changes in mobility patterns after extreme events by linking transportation infrastructure diversity to post-disaster mobility. Finally, the third study employs the transportation diversity approach to investigate modal accessibility and social exclusion. Transportation infrastructure is a sociotechnical system and transport equity is crucial for access to opportunities and services such as jobs and infrastructure. The social exclusion caused by transport inequity could be intensified after natural disasters that can cause failure in a transportation system. One approach to determine transport equity is access to transportation modes. Common catchment area approaches to assess the equity of access to transportation modes cannot differentiate between the equity of access to modes in sub-regions of an area. The transportation diversity approach overcomes this shortcoming, and it is applied to all transportation modes in NYC zip codes to measure the equity of access. Zip codes were grouped in quartiles based on their transportation diversity. Using the American Community Survey data, a set of important socioeconomic and transport usage factors were compared in the quartile groups. The results indicated the relationship between transportation diversity and income, vehicle ownership, commute time, and commute mode. This relationship highlighted that social exclusion is linked with transport inequity. The results also revealed that the inequity of the transport system in zip codes with low transportation diversity affects poor individuals more than non-poor and the zip codes with a majority of black and Hispanic populations are impacted more. Further consideration of the impacts of Hurricanes Irene and Sandy in NYC shows that people in areas with a lower transportation diversity were affected more and the transport inequity in these areas made it difficult to cope with these disasters and caused post-disaster social exclusion. Therefore, enhancing transportation diversity should support transport equity and reduce social exclusion under normal situations and during extreme events. Together, these three studies illustrate the influence of transportation diversity on the resilience of this infrastructure. They highlight the importance of the provision and distribution of all transportation modes, their influence on mobility during normal situations and extreme events and their contribution toward mitigating social exclusion. Finally, these studies suggest that transportation diversity can contribute to more targeted and equitable transportation and community resilience planning, which should help decision-makers allocate scarce resources more effectively.

    Climate Change Relocation as an Adaptation Strategy: from Taboo to Opportunity
    Bukvic, Anamaria (Virginia Tech, 2012-07-19)
    Relocation is often taboo among policy makers and planners due to its political, social, and ethical connotations, and although increasingly mentioned as one of the potential climate change adaptation strategies, it mostly adheres to rhetoric with limited discussion of its actual implementation. Scientific study and observation indicate the imminence of climate change impacts, many of which may exceed the adaptive capacity of vulnerability hotspots. Therefore, it is imperative to reassess this response option in the light of its past negative reputation, the success of current initiatives, and decision makers' evolving perception of relocation as an adaptation option. The main objective of this dissertation research is to determine the need for, interest in, and prospects for community relocations as an adaptation option; explore ways to address limitations associated with this alternative, and identify opportunities that could emerge from the relocation process. This study reviews experiences from the past and current relocation efforts and gauges the current level of interest in and support for this adaptation option among policy makers and planners. It also provides conceptual models - the relocation scenario, its digitalized simulation, the Climate Change Relocation Leaf, and the Relocation Suitability Index - designed to help communities, policy makers and planners explore this alternative. The research commences with a comprehensive literature review of theoretical knowledge, past experiences, current case studies, and the existing state of institutional, political, and social perspectives related to climate change migration and relocation. It continues with a comparative content analysis of climate change adaptation plans to elucidate the relocation rhetoric utilized in the selected texts at what frequency and in what context. Next, the study represents the climate change relocation models and a scenario developed to engage decision-makers and stakeholders in assessing the need for and possibility of relocation. Lastly, the project concludes with the development of a conceptual and tabular framework for the Relocation Suitability Index and subsequent simulation designed to compare possible relocation host sites systematically based on their absorption capacity.

    The Commercialization of Smallholder Farming—A Case Study from the Rural Western Middle Hills of Nepal
    GC, Raj K.; Hall, Ralph P. (MDPI, 2020-04-30)
    A vast majority of farmers in the rural middle hills of Nepal are smallholders who often use family labor and follow traditional agricultural and water management practices. This study examines a range of perspectives (from rural farmers to development experts) on the limited commercialization of rural agriculture in this region of Nepal and the potential approaches to promoting agricultural growth and commercialization among small landholders. An analysis of household surveys, key informant interviews, and focus group discussions in three wards of Kaski, Syangja, and Palpa districts of Nepal revealed that nearly one-third of farmers left their agricultural lands barren or only partly cultivated, and more than one-third were not motivated to engage in agricultural activities. This lack of motivation was found to be connected with limited or no access to irrigation water, poor production systems, a lack of access to markets, a low return on investment in agriculture, the low social status of farm-work, the incidence of crop infestations, and fear of production risks due to extreme climatic factors (such as low/high rainfall, droughts, etc.). Remittances related to outmigration were also found to be important factors limiting a farmer’s involvement in agriculture, which also creates labor shortages. This research confirms that, for agricultural production to be profitable and commercial, households need to receive qualified technical support to introduce new technologies, engage in markets, access input suppliers and service providers, and adopt high-value production crops and related techniques. Households that receive an income from government jobs, private sources, and remittances reported agriculture being a laborious and difficult task. Addressing these mediating factors along with the provision of effective crop insurance and subsides for the lower-income segments of the population, has the potential to (re)engage rural households in farming activities. Such an approach could provide a way to realize the government’s plans to commercialize smallholder farming.

    Comparative Analysis of Current Performance-Based Maintenance Methods to Improve Virginia Highways
    Arcella, Joseph Louis (Virginia Tech, 2013-04-12)
    This research was completed in two phases; phase-one involved a mini-scan study of the highway maintenance industry to identify the current state-of-practice in performance-based maintenance contracting (PBMC). Phase one gathered information on domestic and foreign agencies currently using performance-based maintenance on highways. Phase two used the mini-scan study information to build, compare and analyze agency timelines (i.e., VDOT to others). Timelines included major milestones at each agency; milestones which enabled innovation in the field of performance-based contracting. The purpose of comparing VDOT to other agencies was to provide VDOT with industry best practices as well as recommendations for future contract evolutions. Timelines were constructed for Florida DOT, Main Roads of Western Australia, England\'s Highways Agency and New Zealand Transport Agency. Connection links were made between VDOT and the other four agencies based on similarities in procurement laws and maintenance milestones (i.e., 1st Design-Build project). The timeline linkages and collection of information on benefits associated with PBMC (compared to traditional method-based maintenance) were used to make five recommendations for VDOT\'s future maintenance program. VDOT recommendations were: Use performance-based contracting on secondary roads, use area-wide contracts to cover addition facilities, shift VDOT TAMS focus from lowest-cost to a best-value approach similar to England\'s Managing-Agent Contractor, devise a strategic network of highways to prioritize maintenance, use key performance indicators to align Maintenance Division objectives with overall VDOT organization. Recommendations also considered the current restrictions imposed by Virginia procurement laws.

    The Complex Relationship between Capacity and Infrastructure Project Delivery: The Case of the Indian National Urban Renewal Mission
    An, Yehyun; Hall, Ralph P.; Yoon, Taekwan (MDPI, 2021-08-20)
    Capacity development (CD) interventions are becoming a vital component of development projects. However, there is a lack of information about the relationships between capacity and project delivery. This paper presents the results of a study of how CD was applied to one of India’s largest urban infrastructure programs. While the Indian government considered a lack of capacity to be the main problem in project delivery, there is little evidence that explains the relationships between capacity and project delivery. This study analyzes the content of 58 interviews with project engineers, managers, and administrators about the hurdles they experienced at each stage of project delivery and seeks to understand these hurdles through the lens of CD. The study identifies the influence of capacity factors on project delivery and the converse influence of project performance and outcomes on CD. Ultimately, this study reveals the complex two-way interactions between capacity and project delivery.

    Considerations for Informed Pursuit of Zero Waste: Lessons from Two Case Studies
    Thangavelu, Jennifer Anne (Virginia Tech, 2013-11-14)
    Starting in the early 2000s, a number of U.S. communities have adopted "zero waste" commitments to reduce waste as much as possible through recycling, composting, and other means. Little in-depth information exists about the impetus for or efficacy of these efforts. The author sought to build knowledge on the topic by conducting case studies of two communities: the zero waste efforts of Boulder, Colorado, and the Zero Waste Zones established in Atlanta. The two cases presented an interesting contrast, in terms of sector driving zero waste: public in Boulder, and private in Atlanta. The study aimed to use the experiences of these two communities, supplemented with background research on materials management and application of relevant theory, to develop a set of considerations for more informed pursuit of zero waste. The author gathered qualitative data by conducting unstructured interviews of the actors involved with the zero waste efforts in Boulder and Atlanta. Interview questions concerned, e.g., zero waste goals and plans, the impacts of zero waste on the business or organization, and influential individuals or organizations. The study produced the following set of considerations: Definition of waste determines priorities and impacts of zero waste efforts; responsibility for waste arbitrarily resides with consumers and local government instead of producers; the private, public, and nonprofit sectors each play important roles in waste reduction; local government should not bear the full burden of materials management; and state and federal government can offer useful policy tools to advance zero waste.

    Decentralization and Hospital Governance in Rural Paraguay
    Erickson, Julie B. (Virginia Tech, 2012-04-27)
    This study explores hospital board governance, particularly the dimensions of accountability, transparency and civic participation, within Local Health Councils (LHCs) in two locations in rural Paraguay. The democratization and decentralization efforts of the Paraguayan federal government in the last 20 years resulted in creation of the LHCs, but little research has been conducted on how these entities are now working in comparison to the expectations envisioned for them. This study examines LHC member understanding and practices by conducting semi-structured interviews with council members in two different locations. I reviewed relevant Paraguayan law and compared LHC member responses with the legal expectations of the role of the LHC and council member responsibilities. I also reviewed several health council organizational documents, such as rules and procedures, financial statements and by-laws, with the same intent. Using interpretive social science methods, I analyzed this data in conjunction with the information I gathered through participant-observation during my Peace Corps service in one of the communities examined here. This study finds that local health councils face numerous challenges to governance, including member role confusion, few implemented planning and oversight processes, weak systems of accountability and a lack of resources and support given to LHCs, creating a great challenge to meet expectations set out for them by federal law.

    Designing Transdisciplinarity: Exploring Institutional Barriers and Drivers of Collaborative Transdisciplinary Teaching
    Velez, Anne-Lise K.; Hall, Ralph P.; Lewis, Stephanie N. (Informa, 2021-01-01)
    Employers increasingly desire new graduates to work across boundaries, in teams, and with developed soft skills, especially in public affairs. Likewise, students increasingly seek academic experiences for learning, practicing, and honing transferable, competency-based skills. This suggests instructors should explore alternative pedagogy engaging problem definition and transdisciplinary teamwork. We describe institutional drivers and barriers to collaborative transdisciplinarity in undergraduate teaching and the structure and processes involved in developing a co-taught studio-based capstone involving public affairs students and varied other unrelated majors. We describe the structure through which the “SuperStudio” (1) combines topic concentrations with a shared policy context allowing students to apply disciplinary knowledge to define transdisciplinary problems and (2) fosters collaborative teaching and strategic exploration of overarching issues like problem framing, equity, and effective communication. We then offer lessons learned regarding the drivers and barriers to such efforts, and advice from institutional decision-makers on designing such courses at other institutions.

    Does Rural Water System Design Matter? A Study of Productive Use of Water in Rural Nepal
    GC, Raj K.; Ranganathan, Shyam; Hall, Ralph P. (MDPI, 2019-09-23)
    In Nepal, rural water systems (RWS) are classified by practitioners as single-use domestic water systems (SUS) or multiple-use water systems (MUS). In the rural hills of Nepal, subsistence farming communities typically use RWS to support income-generating productive activities that can enhance rural livelihoods. However, there is limited research on the extent of existing productive activity and the factors enabling these activities. This paper examines the extent of water-related productive activities and the factors driving these activities based on a study, undertaken between October 2017 to June 2018, of 202 households served from five single-use domestic water systems and five multiple use water systems in the mid-hills of Nepal. The research found that a majority (94%) of these households engaged in two or more productive activities including growing vegetables and horticulture crops, raising livestock, and producing biogas and Rakshi (locally-produced alcohol), regardless of the system design, i.e., SUS vs. MUS. Around 90% of the households were engaged in productive activities that contributed to over 10% of their mean annual household income ($4,375). Since the SUS vs. MUS classification was not found to be a significant determinant of the extent of productive activity, the households were reclassified as having high or low levels of productive activity based on the quantity of water used for these activities and the associated earned income. A multinomial logistic regression model was developed to measure the relative significance of various predictors of high productive activity households. Five dominant predictors were identified: households that farm as a primary occupation, use productive technologies, are motivated to pursue productive activities, have received water-related productive activity training, and have received external support related to productive activities. Whereas MUS are designed for productive activity, nearly every household in SUS communities was involved in productive activities making them ‘de-facto’ MUS. These results challenge the current approach to rural water provision that views SUS and MUS as functionally different services.
