Destination Areas (DAs)
Permanent URI for this community
Destination Areas provide faculty and students with new tools to identify and solve complex, 21st-century problems in which Virginia Tech already has significant strengths and can take a global leadership role. The initiative represents the next step in the evolution of the land-grant university to meet economic and societal needs of the world. DAs connect the full span of relevant knowledge necessary for addressing issues comprehensively. Humanistic, scientific, and technological perspectives are addressed in relationship to one another and they are treated as complementary to overcome traditional academic boundaries, such as those that separate the STEM fields and liberal arts.

- Biodiversity conservation, project planning, and gender: Experiences from the fieldMaldonado, Oscar (Virginia Tech. University Libraries, 2017-04-20)Biodiversity conservation paradigms have considerably evolved during the last 20 years. A better understanding of the complexities that conservation entails has allowed reconsidering strict conservation strategies and adopting more inclusive and comprehensive approaches. Although cultural and gender aspects are increasingly deemed to be conditions for conservation success, many issues still remain to be fully included in the conservation practice. Oscar Maldonado shares his experiences in incorporating gender, culture and other sensitive social aspects in sound conservation planning, and explains how he has methodologically overcame methodological challenges and limitations.

- Chasing Water in a Rapidly Changing WorldRichter, Brian D. (Virginia Tech. University Libraries, 2017-04-07)Water shortages are now affecting half the world’s population, disrupting food and energy security as well as urban water supplies in many cities. The overuse of water and associated drying of rivers, lakes, and aquifers has become a leading cause of freshwater species imperilment. Climate change forecasts foretell even greater challenges in many water-scarce regions. These threats to our water future can be ameliorated, but it will require bold and concerted action on the part of governments, city leaders, and farmers. This presentation will highlight the key solutions that must be implemented. “Brian Richter has been a global leader in water science and conservation for more than 25 years. He is the Chief Scientist for the Global Water Program of The Nature Conservancy, an international conservation organization, where he promotes sustainable water use and management with governments, corporations, and local communities. He is also the President of Sustainable Waters, a global water education organization. Brian has consulted on more than 120 water projects worldwide. He serves as a water advisor to some of the world’s largest corporations, investment banks, and the United Nations, and has testified before the U.S. Congress on multiple occasions. He also teaches a course on Water Sustainability at the University of Virginia. Brian has developed numerous scientific tools and methods to support river protection and restoration efforts, including the Indicators of Hydrologic Alteration software that is being used by water managers and scientists worldwide. Brian was featured in a BBC documentary with David Attenborough on “How Many People Can Live on Planet Earth?” He has published many scientific papers on the importance of ecologically sustainable water management in international science journals, and co-authored a book with Sandra Postel entitled Rivers for Life: Managing Water for People and Nature (Island Press, 2003). His new book, Chasing Water: A Guide for Moving from Scarcity to Sustainability, was published by Island Press in June 2014.” - National Geographic, http://voices.nationalgeographic.com/author/brichter/

- CrowdLayout: Crowdsourced Design and Evaluation of Biological Network VisualizationsSingh, Divit P.; Lisle, Lee; Murali, T. M.; Luther, Kurt (ACM, 2018-04)Biologists often perform experiments whose results generate large quantities of data, such as interactions between molecules in a cell, that are best represented as networks (graphs). To visualize these networks and communicate them in publications, biologists must manually position the nodes and edges of each network to reflect their real-world physical structure. This process does not scale well, and graph layout algorithms lack the biological underpinnings to offer a viable alternative. In this paper, we present CrowdLayout, a crowdsourcing system that leverages human intelligence and creativity to design layouts of biological network visualizations. CrowdLayout provides design guidelines, abstractions, and editing tools to help novice workers perform like experts. We evaluated CrowdLayout in two experiments with paid crowd workers and real biological network data, finding that crowds could both create and evaluate meaningful, high-quality layouts. We also discuss implications for crowdsourced design and network visualizations in other domains.

- A Declarative Approach to Hardening Services Against QoS VulnerabilitiesKwon, Young-Wo; Tilevich, Eli (IEEE, 2011)The Quality of Service (QoS) in a distributed service-oriented application can be negatively affected by a variety of factors. Network volatility, hostile exploits, poor service management, all can prevent a service-oriented application from delivering its functionality to the user. This paper puts forward a novel approach to improving the reliability, security, and availability of service-oriented applications. To counter service vulnerabilities, a special service detects vulnerabilities as they emerge at runtime, and then hardens the applications by dynamically deploying special components. The novelty of our approach lies in using a declarative framework to express both vulnerabilities and hardening strategies in a domain-specific language, independent of the service infrastructure in place. Thus, our approach will make it possible to harden serviceoriented applications in a disciplined and systematic fashion.

- Designing for Schadenfreude (or, how to express well-being and see if youʼre boring people)André, Paul; Schraefel, M.C.; Dix, Alan; White, Ryen W.; Bernstein, Michael; Luther, Kurt (ACM, 2010)This position paper presents two studies of content not normally expressed in status updates—well-being and status feedback—and considers how they may be processed, valued and used for potential quality-of-life benefits in terms of personal and social reflection and awareness. Do I Tweet Good? (poor grammar intentional) is a site investigating more nuanced forms of status feedback than current microblogging sites allow, towards understanding self-identity, reflection, and online perception. Healthii is a tool for sharing physical and emotional well-being via status updates, investigating concepts of self-reflection and social awareness. Together, these projects consider furthering the value of microblogging on two fronts: 1) refining the online personal/social networking experience, and 2) using the status update for enhancing the personal/social experience in the offline world, and considering how to leverage that online/offline split. We offer results from two different methods of study and target groups—one co-workers in an academic setting, the other followers on Twitter—to consider how microblogging can become more than just a communication medium if it facilitates these types of reflective practice.
- Detecting Malicious Landing Pages in Malware Distribution NetworksWang, Gang Alan; Stokes, Jack W.; Herley, Cormac; Felstead, David (IEEE, 2013-06)Drive-by download attacks attempt to compromise a victim’s computer through browser vulnerabilities. Often they are launched from Malware Distribution Networks (MDNs) consisting of landing pages to attract traffic, intermediate redirection servers, and exploit servers which attempt the compromise. In this paper, we present a novel approach to discovering the landing pages that lead to drive-by downloads. Starting from partial knowledge of a given collection of MDNs we identify the malicious content on their landing pages using multiclass feature selection. We then query the webpage cache of a commercial search engine to identify landing pages containing the same or similar content. In this way we are able to identify previously unknown landing pages belonging to already identified MDNs, which allows us to expand our understanding of the MDN. We explore using both a rule-based and classifier approach to identifying potentially malicious landing pages. We build both systems and independently verify using a high-interaction honeypot that the newly identified landing pages indeed attempt drive-by downloads. For the rule-based system 57%of the landing pages predicted as malicious are confirmed, and this success rate remains constant in two large trials spaced five months apart. This extends the known footprint of the MDNs studied by 17%. The classifier-based system is less successful, and we explore possible reasons.
- Distributed Storage Systems with Secure and Exact Repair - New ResultsTandon, Ravi; Amuru, SaiDhiraj; Clancy, Thomas Charles III; Buehrer, R. Michael (IEEE, 2014-02)Distributed storage systems (DSS) in the presence of a passive eavesdropper are considered in this paper. A typical DSS is characterized by 3 parameters (n, k, d) where, a file is stored in a distributed manner across n nodes such that it can be recovered entirely from any k out of n nodes. Whenever a node fails, d ∈ [k, n) nodes participate in the repair process. In this paper, we study the exact repair capabilities of a DSS, where a failed node is replaced with its exact replica. Securing this DSS from a passive eavesdropper capable of wiretapping the repair process of any l < k nodes, is the main focus of this paper. Specifically, we characterize the optimal secure storagevs- exact-repair-bandwidth tradeoff region for the (4, 2, 3) DSS when l = 1 and the (n, n − 1, n − 1) DSS when l = n − 2.
