The Trade-Security Nexus And U.S. Policy Making In Critical Minerals, Yujia He

Patterson School of Diplomacy and International Commerce Faculty Publications

The United States increasingly relies on import to meet its demand for critical minerals. Using the case of rare earth elements (REEs), this paper analyzes the conditions and the strategies for the U.S. government to address import dependence. The paper finds that market factors, including the lack of comparable and sufficient substitutes and recycling, the high ratio of import relative to consumption, the high concentration of import supply by country, and regulations from the major supplier country, were insufficient to prompt intervention. Significant policy action only occurs when changing circumstances turn import dependence into perceived national security threats to the …

There’S Nowhere To Hide: Artificial Intelligence And Privacy In The Fourth Industrial Revolution, Sarah Denton, Eleonore Pauwels, Yujia He, Walter G. Johnson

Patterson School of Diplomacy and International Commerce Faculty Publications

At its core, artificial intelligence (AI) optimizes data. Machine-learning algorithms, one component of AI, are trained using massive datasets curated by humans to predict various aspects of our daily lives. Such predictive intelligence could be a positive force amplified by continued decentralization of the technology. Or, ubiquitous cognition and surveillance could be a disruptive force amplified by the unregulated proliferation of AI technologies. Yet, though we will certainly see more and more AI systems being integrated into every facet of our infrastructures, homes, and bodies, the proliferation of AI technology isn’t the problem. A privacy-security quagmire arises from the interconnectivity …

Parallel Design Of A Product And Internet Of Things (Iot) Architecture To Minimize The Cost Of Utilizing Big Data (Bd) For Sustainable Value Creation, Ryan Bradley, Ibrahim S. Jawahir, Niko Murrell, Julie Whitney

Institute for Sustainable Manufacturing Faculty Publications

Information has become today's addictive currency; hence, companies are investing billions in the creation of Internet of Things (IoT) frameworks that gamble on finding trends that reveal sustainability and/or efficiency improvements. This approach to “Big Data” can lead to blind, astronomical costs. Therefore, this paper presents a counter approach aimed at minimizing the cost of utilizing “Big Data” for sustainable value creation. The proposed approach leverages domain/expert knowledge of the system in combination with a machine learning algorithm in order to limit the needed infrastructure and cost. A case study of the approach implemented in a consumer electronics company is …

How China Is Preparing For An Ai-Powered Future, Yujia He

Patterson School of Diplomacy and International Commerce Faculty Publications

U.S. leadership in artificial intelligence (AI) research and development (R&D) may be challenged by China’s recent and centralized policy planning aimed at rapidly developing AI-related technologies. The Chinese government supports AI as a strategic area supported by high-level policies with ambitious and quantifiable targets, inter-ministry coordination, government funding for research and development, support for workforce development, and suggestions for international collaboration and expansion. Still, as a relative latecomer in the global AI race, China faces numerous challenges to implement its policy planning, including short-term skills gap and long-term institutional constraints.

The analysis covers project goals, requirements and support for participants, policy impact, digital tools and data privacy.

Impermeable Assemblages: Flooding, Urban Infrastructure, And Stormwater Politics In São Paulo, Brazil, Nate Millington

Theses and Dissertations--Geography

This project analyzes efforts to remake the relationship between water and city in São Paulo, Brazil. Currently experiencing overlapping problems of flooding, scarcity, and pollution, São Paulo illustrates the challenges of managing water in a contemporary mega-city. This dissertation subsequently considers the city’s water management through an approach that borrows from urban political ecology, social studies of science, and post-colonial urban theory. With an epistemological grounding in these literatures, this project analyzes ongoing conversations about water management in São Paulo, and focuses on how water is encountered and engaged with in the landscape by engineers, artists, and activists. This project …

Using Wii Technology And Experiential Learning To Teach Newtonian Mechanics To Rural Middle School Students, Joseph S. Dvorak, Tanya C. Franke-Dvorak, Shane Neel

Biosystems and Agricultural Engineering Faculty Publications

This study looked at the effects of an experiential learning activity using the accelerometer in the Wii Remote to teach basic concepts of Newtonian mechanics, e.g., acceleration, to middle school students in a rural school district. A major prerequisite for students at the mid-level in biosystems engineering programs is that they have a good knowledge of basic science, including physics. Education in these concepts must begin before college, such as at the middle school level. Improvements in science education are vitally necessary to achieve essential learning outcomes for middle school students in the U.S. and to prepare these students for …

The Use Of Improved Technology And Market-Based Incentives To Increase Forest Resource And Biodiversity Conservation In Rwanda, Kelly M. Rayens

Theses and Dissertations--Forestry and Natural Resources

This study evaluated the effectiveness of two distinct approaches to ecosystem conservation in Rwanda’s Nyungwe National Park: cookstove technology adoption and market-based policy instruments. A June 2014 survey of 250 households revealed that use of improved cookstove technology dramatically decreased fuelwood consumption for households in rural Rwanda, but that design, engineering and conflicting policy issues can hamper the widespread use of energy-efficient cooking technology. The second component of this research used the analytic hierarchy process (AHP) within a multi-criteria analysis (MCA) framework to explore the options for designing and implementing market-based instruments around the country’s conservation targets, particularly the highly …

Let’S Play: Understanding The Role And Significance Of Digital Gaming In Old Age, Julie A. Skalsky Brown

Theses and Dissertations--Gerontology

Despite a marked increase in the use of digital games among older persons, there is insufficient research that provides insight into the gaming experiences of this population. A major demographic shift within the senior gaming market has ushered in a new perspective on the use of digital games as a tool for physical and cognitive health, and improved socialization. It is proposed that individual notions of play, which are developed over the life course, influence digital game play engagement and interaction preferences, and contribute to well-being. This study explored how self-perceptions of play over the course of the senior gamer’s …

Augmented Realities And Uneven Geographies: Exploring The Geolinguistic Contours Of The Web, Mark Graham, Matthew Zook

Geography Faculty Publications

This paper analyzes the digital dimensions of places as represented by online, geocoded references to the economic, social, and political experiences of the city. These digital layers are invisible to the naked eye, but form a central component of the augmentations and mediations of place enabled by hundreds of millions of mobile computing devices and other digital technologies. The analysis highlights how these augmentations of place differ across space and language and highlights both the differences and some of the causal factors behind them. This is performed through a global study of all online content indexed within Google Maps, and …

Ecological Restoration's Genetic Culture: Participation And Technology In The Making Of Landscapes, Jairus Rossi

Theses and Dissertations--Geography

Practitioners of ecological restoration are increasingly adopting a genetic perspective when recreating historical landscapes. Genes are often endowed with the capacity to reveal specific and distinct relationships between organisms and environments. In this dissertation, I examine how genetic technologies and concepts are shaping ecological restoration practices. This research is based on two and a half years of fieldwork in Chicago. I employed participant observation and semi-structured interviews to compare how restorationists in two plant science institutions employ genetic concepts in their projects. One institution uses high-tech genetic methods to guide practice while the other uses lower-tech genetic approaches. Each group …
