Privacy-Preserving Social Network Analysis, Christine Marie Task

Open Access Dissertations

Data privacy in social networks is a growing concern that threatens to limit access to important information contained in these data structures. Analysis of the graph structure of social networks can provide valuable information for revenue generation and social science research, but unfortunately, ensuring this analysis does not violate individual privacy is difficult. Simply removing obvious identifiers from graphs or even releasing only aggregate results of analysis may not provide sufficient protection. Differential privacy is an alternative privacy model, popular in data-mining over tabular data, that uses noise to obscure individuals' contributions to aggregate results and offers a strong mathematical …

The Restoration Process: Lessons From A Community-Based Conservation Initiative In Tunkhel, Mongolia, John Wendt

Independent Study Project (ISP) Collection

As policy makers transition away from central planning, Mongolia’s natural resource professionals are challenged with cultivating community support for stewardship in a time of escalating ecological disturbance. Nutag Action Research Partners has partnered with community members and government officials in Tunkhel, a small village in north-central Mongolia, to develop local resource management capacity and jointly draft a Conservation Plan for a commonly grazed riparian pasture. This study is a preliminary assessment of the ecological and social factors influencing project implementation. Information was collected using a variety of qualitative methods including meeting observation, surveys, interviews, photographs, and a review of previous …

Existential Avalanche The Lived Experience Of Climate Change In Dolpo And Mustang, Nepal, Keegan Mcchesney

Independent Study Project (ISP) Collection

Himalayan communities stand precariously in an era of phenomenological uncertainty. Climate change is merely a lens through which we may observe and begin to understand such localized modern complexities. The people of the Tarap Valley in Dolpo, Nepal have experienced an increase in avalanches, snow leopard attacks and unpredictable precipitation patterns in recent years. In upper Mustang, Nepal, people have endured the harshest winter in generations and suffered from reduced water access. Environmental, climatic and weather related changes in both Himalayan districts have severely impacted traditional livelihoods and led some to adopt modern means of adaptation. Despite the scientific evidence …

Utilizing Illinois State University's Environmental Legacy And Historical Collections To Sustain A Global Future, Melissa Nergard

Theses and Dissertations

The scholarly capital of materials at Illinois State University includes numerous natural history collections from the mid-nineteenth century that hold significant research and historical value. Changes in pedagogical methods and academic leadership, however, created confusion and territorial competition in who would preserve and manage the collections. Consequently some specimens from those early collections have been both lost and forgotten. This thesis used a systems approach to track the material losses incurred when institutional support shifted in the 1870s, and the original collectors and curators left Central Illinois for national interests in Washington, D.C. Yet, historical environmental collections have become increasingly …

Results Of Archaeogeophysical Investigations Of The Fowler - Clark Farm Mattapan, Boston, Massachusetts, Brian N. Damiata, John M. Steinberg

Andrew Fiske Memorial Center for Archaeological Research Publications

Ground penetrating radar (GPR) and Frequency-Domain Electromagnetic (FDEM) surveys were employed over an extensively modified 50 m x 65 m city lot containing a farmhouse initially constructed between 1786 and 1806 and a later barn. Both geophysical methods suggested that most of the lot had experienced substantial disturbance and that there was limited sub - surface preservation. Both the GPR and EM surveys indicated a scatter of metallic debris and other disturbance s in the back yard at depths up to 1 m. Most of the front yard also presents as disturbed, except for two unusual but limited buried surfaces …

Energy Efficiency And Conservation Attitudes: An Exploration Of A Landscape Of Choices, Mersiha Spahic Mcclaren

Dissertations and Theses

This study explored energy-related attitudes and energy-saving behaviors that are no- or low-cost and relatively simple to perform. This study relied on two data sources: a longitudinal but cross-sectional survey of 4,102 U.S. residents (five biennial waves of this survey were conducted from 2002 to 2010) and a 2010 cross-sectional survey of 2,000 California residents. These two surveys contained data on two no- and low-cost behaviors: changing thermostat setting to save energy (no-cost behavior) and CFL installation behavior (low-cost behavior). In terms of attitudes, two attitudinal measures emerged from these data following a Cronbach's alpha and Confirmatory Factor Analysis (CFA): …

Red Meat, Our Health And Alfalfa--Separating Scientific Fact From Opinions, Policy, Politics, And Bureaucracy, Peter Ballerstedt

Kentucky Alfalfa and Stored Forage Conference

The general public is becoming increasingly aware of the failure of the official nutritional policy of United States and other countries. Books like Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health (Taubes, 2008), Why We Get Fat and What To Do About It (Taubes, 2011) and The Big Fat Surprise: Why Butter, Meat and Cheese Belong in a Healthy Diet (Teicholz, 2014) have exposed the disconnect between nutrition science and nutrition policy, and have told the story of how we’ve come to this point in history.

What Have We Learned From The Deepwater Horizon Disaster? An Economist’S Perspective, Daniel R. Petrolia

Journal of Ocean and Coastal Economics

This paper outlines what we have learned about the impacts of the Deepwater Horizon (DWH) oil disaster from the economics discipline as well as what effect the DWH disaster has had on the economics discipline. It appears that what we know about the economic impact of the DWH spill today is limited, possibly because such analysis is tied up in the federal Natural Resource Damage Assessment (NRDA) process and other state-led efforts. There is evidence, however, that the NRDA process has changed over time to de-emphasize economic valuation of damages. There is also evidence that economists may be producing fewer …

Digital Forensics Tool Interface Visualization, Roberto A. Altiero

CCAC Theses and Dissertations

Recent trends show digital devices utilized with increasing frequency in most crimes committed. Investigating crime involving these devices is labor-intensive for the practitioner applying digital forensics tools that present possible evidence with results displayed in tabular lists for manual review. This research investigates how enhanced digital forensics tool interface visualization techniques can be shown to improve the investigator's cognitive capacities to discover criminal evidence more efficiently. This paper presents visualization graphs and contrasts their properties with the outputs of The Sleuth Kit (TSK) digital forensic program. Exhibited is the textual-based interface proving the effectiveness of enhanced data presentation. Further demonstrated …

Anthropogenic Impacts As Revealed From Sediment Cores From Punderson Lake Ohio, Ronald A. Van Blarcum

ETD Archive

Sediment core archives provide a history of data useful for serving as a long-term monitoring reserve to evaluate chronological events of contamination to lake systems. This could be an effective tool for continual environmental management, monitoring and potential restoration efforts. This method is also very cost-effective without the addition of a water quality monitoring station on site. Taking 3 sediment cores from Punderson Lake Ohio for analysis has allowed associating variations in select metals to anthropogenic events or activities we can determine a time frame with limited uncertainty and resolve the intensity of anthropogenic contamination to the lake starting with …

Privacy Preserving Data Mining For Numerical Matrices, Social Networks, And Big Data, Lian Liu

Theses and Dissertations--Computer Science

Motivated by increasing public awareness of possible abuse of confidential information, which is considered as a significant hindrance to the development of e-society, medical and financial markets, a privacy preserving data mining framework is presented so that data owners can carefully process data in order to preserve confidential information and guarantee information functionality within an acceptable boundary.

First, among many privacy-preserving methodologies, as a group of popular techniques for achieving a balance between data utility and information privacy, a class of data perturbation methods add a noise signal, following a statistical distribution, to an original numerical matrix. With the help …

Participatory And Holistic Approaches With Grassland Farmers And Development Of Policies, Alain Peeters

IGC Proceedings (1977-2023)

The world is changing rapidly. Grassland farmers and ruminant livestock breeders will have to adapt to these changing environmental, social and economic conditions. Research can help them at the condition that linear ‘top-down’ technology transfer methods are abandoned for the benefit of participatory and holistic approaches. These approaches classified in the generic term of ‘Farming System Research’ consider farmers as real research partners, and they merge farmer’s and scientist’s ideas with those of other stakeholder types. They combine scientist’s and farmer’s knowledge for creating fast innovations, easily adopted by farmers since farmers themselves contribute to their design and their development. …

Population Genetic Structure Of Asclepias Tuberosa In Northwest Iowa: A Comparison Within And Between Remnant Prairies And Commercially Available Seed, Jeffrey T. Ploegstra, Brittany De Ruyter, Tony Jelsma

Journal of the Iowa Academy of Science: JIAS

Isolated in scattered remnants, less than 0.1% of Iowa’s original tallgrass prairie remains. The small populations remaining are at risk for reduced genetic diversity, inbreeding depression, and outbreeding depression. In light of these concerns, we used microsatellite analysis to assess the genetic structure of butterfly milkweed (Asclepias tuberosa) populations on prairie remnants in northwest Iowa. We compared remnant populations with a restoration population at Dordt College in Sioux Center, Iowa, and with an Oklahoma seed source. Microsatellites identified for use in common milkweed (Asclepias syriaca) had sufficient polymorphism information content (PIC) across the butterfly milkweed ( …
