Governing Smart Cities and the Ethical Considerations of Big Data

By Ken Ogata

From smartphones to surveillance cameras, to automatic doors and artificial intelligence, the cities we live in have become “smarter,” carrying the promise of productivity and modernization. While “smart” technology seemingly makes our lives easier, are we giving up the benefits of privacy and individualism?

In a new book, Governing Smart Cities as Knowledge Commons, edited by Brett M. Frischmann, Michael J. Madison, and Madelyn Rose Sanfilippo, experts in law, policy, and information science examine how we can properly govern “smart” cities through models based on ethical and social considerations, and information science.

With the increasing integration of technology into our daily lives, the amount of data and information that is gathered, stored, and analyzed by cities has skyrocketed.

“Residents are connected to each other and to governments and other organizations by fiber and wireless connections.” The authors of Governing Smart Cities as Knowledge Commons write in Part 1 of the book, “‘The people’ and their environments are rendered and represented digitally in the bureaucracies of public administration and in the dynamics of everyday life.”

As the role of Big Data becomes more important in city policy, data governance—the standards and regulation for the storage, usage, and disposal of data—has never been more relevant. Dr. Angie Raymond, a coeditor of the book and Professor of Business Law and Ethics at Indiana University, states that many cities in the United States lack the manpower and expertise to efficiently use the data collected.

“The problem a lot of cities are facing is that the skills required to use data are new,” Raymond said. “And unfortunately, cities are oftentimes well behind the curve on being able to find (well-trained) employees.”

Raymond added that many cities lack the infrastructure to store data for proper use later down the road. “The biggest issue for cities is oftentimes cities have been gathering data for a long time . . . they have a repository of data, which is oftentimes a Box folder with some security on it, and a lot of PDFs, which are incredibly difficult to be used.”

The authors also state that modern cities can get wrapped up in hype and adopt “smart” technology for the sake of modernization, not taking the time to consider what data it shares and collects and how to properly govern it.

The book notes that seemingly innocent examples of “smart” technology can have unintended consequences, such as an automatic door with a camera.

“What if the automatic door could identify people prior to opening the door? What if the automatic door could send an alert when an unauthorized person attempts to enter the building?” the authors ask in Part 4: Lessons for Smart Cities. “This requires new sensors, intelligence-generating tools and processes (identification), and automated actions . . . The camera-based system collects much more data than is needed, creating privacy risks that are easily overlooked or underestimated.”

To prevent cases like this, the authors of the book present the Governing Knowledge Commons (GKC) framework as a useful tool when evaluating the governance of smart technology. The book emphasizes the importance of comprehensive public knowledge in regard to data storage and collection, and the implementation of new smart technology across the city.

“We need to figure out a way that we can all use data to produce information, and then we’re sharing it amongst a larger community,” Raymond said. “Commons is just a fancy word for saying we all get together and we know the boundaries and have a set of rules.”

As an example of the GKC framework, Raymond brings up the Dewey Decimal system present in libraries across the country and how it could be used to set up a proper data governance topology for cities.

“It doesn’t matter what library you walk into, if you walk to the fiction section, you can find Stephen King, and (000) is the computer science section in every library all round the world,” said Raymond. “If we could ever develop an actual system where we were using similar variables with similar labels (for city data), we would be in a different place.”

Using the GKC framework as a foundation, the authors of the book provide a set of questions that can be used by administrative governments when considering the pros and cons of installing smart technology:

In the book’s concluding chapters, the authors mention in Part 4 that proper data governance requires comprehensive public knowledge and also community members that are well informed and capable of taking action and voicing concerns about data collections and city projects. “Simply put, cities aren’t smart, but the people living and working in cities might be.”

In making sure that data governance is upheld and smart technology does not infringe upon the rights of citizens, Raymond urges those capable to make sure that their voices are heard. “Citizens need to understand that if you are in the room and you have a voice, there are probably three people not in the room who don’t have a voice.”

Cities themselves can only be as smart as the people living in them. Accountability lies not only in the hands of the experts, but also the larger city community, whose job it is to make sure that we still have a voice in our cities.

Reshaping Agriculture in a Changing Climate with Insights from Predictive Analytics

By Shruti Gosain

We’re in a time where technology is moving faster than ever. In an age of rapidly advancing technology, the intersection of data science, climate science, and agriculture is producing game-changing results. Predictive analytics, a cutting-edge approach to data-driven forecasting, is revolutionizing our ability to foresee and respond to the challenges posed by a changing climate. It’s like having a crystal ball that helps us predict and prepare for the problems that impact society in different ways due to climate change.

The Power of Predictive Analysis in Climate Science

In the world of climate science, researchers use big sets of data from tools like satellites and weather stations. With the help of super-smart computer programs, they can make predictions about things like extreme weather and long-term climate changes. These predictions help us understand what’s happening with the Earth’s climate and get ready for changes like heat waves and storms.

Satellites and weather stations collect a huge amount of data about the weather and climate. Then, with the help of artificial intelligence and machine learning, scientists can predict things like wild weather events, seasonal changes, and long-term shifts in our climate. Now, why is this exciting? Well, think about it: These predictions are like knowing the future, but for the weather. Farmers can use this information to figure out when to plant their crops. If they know there will be a dry spell, they can be ready with extra water. And when we’re talking about big events like hurricanes or floods, predictive analytics helps us get ready—by strengthening our buildings or planning better emergency responses. The case studies in the table below this article illustrate this in more detail.

Predictive Analytics Reshaping the Future of Agriculture

Now, let’s talk more about farming. Farmers rely on the weather and the climate to grow their crops. But with increasing heat and more frequent droughts impacting yields in many growing areas, things are getting tricky. Predictive analytics steps in to help. It looks at large amounts of information like past climate data, how healthy the soil is, and how different crops are doing. Then, it tells farmers when to plant, what to plant, and how much they’ll get when it’s time to harvest. This is what’s called “precision agriculture,” where we use data to be more precise in how we grow food.

Agriculture is inherently dependent on climate, making it one of the sectors most vulnerable to climate change. Predictive analytics offers a lifeline to farmers. By analyzing historical climate data, soil health, and crop performance, predictive models can provide insights into optimal planting times, crop selection, and yield projections. The data-driven decisions enabled by predictive analytics reduce risks, enhance resource management, and increase productivity. For example, in regions facing water scarcity, predictive models can suggest the most efficient irrigation strategies to minimize water wastage. This technology is revolutionizing precision agriculture, optimizing the use of resources and minimizing environmental impact.

Imagine a farmer in a place where it’s superhot and there isn’t much rain. Predictive analytics tells them the best time to plant their crops and how much water to use so they don’t waste any. This means more food on our plates and less waste. So, it’s not just about scientists making cool predictions; it’s about using those predictions to make our world safer and smarter. It’s like having a heads-up about the future and, with that, we can plan better, adapt to change, and protect our planet. Climate science and predictive analytics are like our secret weapons against the unpredictable weather and they’re here to save the day!

Let’s look at a real-life example. In California’s wine country, vineyard managers use predictive analytics to know when to prune the vines, when to water them, and when to pick the grapes. This makes their vineyards strong and good for the environment. The integration of predictive analytics in climate science and agriculture is not just a forward-thinking idea; it’s a necessity in a world facing escalating environmental uncertainties.

Future, Necessities, and Challenges in the Path to Predictive Analytics Mastery

While predictive analytics holds immense promise, challenges exist. The accuracy of predictions depends on the quality and quantity of data, which can be influenced by factors such as data collection infrastructure and access to satellite technology. Additionally, ensuring that predictive models are accessible to farmers, particularly in developing regions, is a critical challenge.

As we look to the future, addressing these challenges is paramount. The integration of predictive analytics in climate science and agriculture is not a luxury but a necessity. It equips us to tackle the evolving climate crisis with proactive strategies, ensuring food security, environmental sustainability, and resilience in the face of uncertainty. Moreover, fostering collaboration between researchers, policymakers, and technology innovators will be essential in harnessing the full potential of predictive analytics to address the pressing challenges of our times.

Conclusion

Predictive analytics is the bridge between knowledge and action in the realms of climate science and agriculture. As we continue to refine these predictive models and make them more accessible, we inch closer to a world where our responses to climate change are not reactions but anticipations, where agriculture adapts seamlessly to shifting climate conditions, and where we collectively move towards a more sustainable and resilient future.

Predictive Analytics Case Studies

Precision Farming for Sustainable Agriculture
Issue: In a region experiencing increasingly erratic weather patterns, farmers faced the daunting task of optimizing crop production while conserving resources and adapting to changing conditions. [Sources: 1, 2]    Solution: Predictive analytics tools were used to analyze historical climate data, soil quality, and crop performance. Using machine-learning algorithms, these tools forecasted ideal planting times and crop varieties as well as recommended precise irrigation schedules. By relying on data-driven decisions, farmers were able to enhance productivity, conserve water, and reduce the environmental footprint of their operations.  
Hurricane Tracking and Preparedness
Issue: Coastal communities were grappling with the increasing frequency and intensity of hurricanes, which necessitated better preparation and response strategies. [Sources: 1, 2]  Solution: Predictive analytics models were developed to track and predict hurricane paths and intensities. These models integrated data from satellites, weather stations, and historical hurricane data. The predictive analytics system provided more accurate forecasts, allowing authorities to issue timely evacuation orders, prepare emergency shelters, and allocate resources effectively. This resulted in improved safety for vulnerable communities during hurricane events.
Climate-Resilient Urban Planning
Issue: Urban areas were facing the dual challenge of population growth and climate change, leading to increased vulnerability to extreme weather events and flooding. [Sources: 1, 2]Solution: Predictive analytics played a pivotal role in urban planning. By analyzing climate data and topography, predictive models identified flood-prone areas and forecasted future vulnerabilities. Urban planners used this information to make informed decisions about infrastructure development, flood defenses, and emergency response plans. This proactive approach ensured that cities were better equipped to handle extreme weather events and protect their citizens.

Cultivating Change: Finding Answers with Sustainable Urban Farming

By Sasha Zvenigorodsky

2019 USDA Food Access Research Atlas, showing the frequency of food deserts throughout the Midwest. The atlas indicates areas where a significant number of residents live more than 1 mile (urban) or 10 miles (rural) from the nearest supermarket.
USDA Food Access Research Atlas, 2019
Low-income census tracts where a significant number or share of residents is more than 1 mile (urban) or 10 miles (rural) from the nearest supermarket.

Most individuals native to Illinois would be shocked to hear that thousands of its residents reside in areas that are considered to be deserts. Not literal deserts, but rather food deserts, urban areas in which it is difficult to buy good-quality or affordable food. Although food deserts aren’t covered by dry sand and hot sun, both types of “deserts” have one glaring similarity: hostile living conditions due to lack of food resources. The 2019 USDA Food Access Research Atlas (at right) demonstrates the frequency of food deserts throughout the Midwest, indicating areas where a significant number of residents live more than 1 mile (urban) or 10 miles (rural) from the nearest supermarket. As food accessibility issues are exacerbated by climate change, these food deserts have the potential to grow even more expansive.

The Midwest Climate Summit concluded in late February, a three-day event hosted by the Midwest Climate Collaborative (MCC; led from Washington University in St. Louis), with the purpose of gathering climate leaders, researchers, and other interested parties to address the escalating issue of climate change and promote new partnerships and collaborations. The Summit hosted multiple speakers and workshops, with topics ranging from agroforestry and silviculture to designing a circular economy.

All these topics have the same main goal: addressing climate change. Here, we explore one session that highlighted the critical impacts of climate change on food accessibility within Illinois. As global warming brings on intense weather fluctuations throughout the United States, standard agricultural practices are jeopardized and traditional farmers are thrown into uncertainty. Without solutions to this issue, food deserts throughout urban areas are likely to expand.

Hosting a panel that included a small regenerative farm, a family orchard, and a beekeeper, the Midwest Climate Summit introduced just that: solutions—specifically, the concept of urban farming.

Urban farming entails both the cultivation and distribution of agricultural products within urban and suburban areas. Hydroponic/aquaponic facilities, community gardens, and rooftop farms are all examples of urban farming. These methods have excellent potential to provide healthy, fresh foods to underserved areas with limited nutritional access. They also address climate change in big ways. For example, various urban-farming methods can utilize less water, less light, and less soil than traditional farming can, proving to be more sustainable and climate-friendly.

The ability to educate and raise awareness on issues like climate change and food insecurity is a big reason why panels like the Midwest Climate Summit are so important. Nonetheless, they are often missing an important target audience: children. Promoting the importance of local urban food systems to school-age children can be the key to establishing more sustainable and environmentally friendly communities over time.

This is demonstrated perfectly by the Gardeneers organization of AmeriCorps. AmeriCorps is an independent agency of the United States government that engages Americans in service positions through stipended volunteer work organizations. One such organization, called Gardeneers, involves urban-farming education targeted towards underprivileged children living in urban food deserts within Chicago. Their mission is to help create a more equitable food system with the help of specialized school garden and farm programs within Chicago’s South and Westside schools. These programs can equip kids with the proper knowledge and skills to positively contribute to the environment and their communities.

“Climate change leaves these kids facing an uncertain future,” says Galina Fesseler, Gardeneers volunteer. “Educating kids about food accessibility and urban farming is a great way to invest in their health and development.”

Food is just one dimension of the larger impact that climate has on a region. Other sessions at the Midwest Climate Summit addressed related topics, such as water and health, which affect people in communities, and shared a wealth of information and resources that communities can use to help with climate resilience.

In collaboration with the MBDH, the MCC developed a prototype Climate Asset Map (CAM), which is an online interface that will help groups from different disciplines and sectors to access and contribute to climate-action information throughout the Midwest, such as information surrounding urban farming. The MCC received feedback from across the Midwest to a survey about information needs that researchers, practitioners, government agencies, and community groups have around climate-related resources. This informed the development of the CAM prototype, which was presented at the Summit for attendees to explore. The model was then refined and has just launched as the Midwest Climate Resource Network (CRN).

Urban farming is just one small example of the many ways to address climate change, hence the need for the CRN. With the help of this resource, organizations like Gardeneers can be interconnected with other groups throughout the Midwest, allowing for collaboration and collective success within the various realms of climate work.

New NSF Convergence Accelerator Midwest disability-related awards

By Aisha Tepede

The National Science Foundation (NSF) has taken a new approach to build upon basic research and discovery to accelerate solutions toward societal impact by providing award funds to academic institutions across the USA with the opportunity to develop research projects.

Individuals who have disabilities deal with hindrances restricting them from achieving better economic opportunities, quality of life, health, and wellness. The NSF’s Convergence Accelerator program enables universities and nonacademic institutions to develop solutions to address societal challenges through convergence research and innovation within a collaborative and multidisciplinary effort. Recently, the program made 16 awards under its Track H: “Enhancing Opportunities for Persons with Disabilities,” including 6 in the Midwest. The transdisciplinary program builds upon basic research to develop new technologies and accelerate novel solutions that can address challenges faced by persons with disabilities.

One arena of the opportunities includes accessibility for those who are visually impaired.

Saint Louis University, in partnership with nonprofit and industry collaborators, received funding for a program that focuses on those with blindness or visual impairments (BVI). The program aims to address the disparities seen among the BVI population. With many members being disproportionately unemployed, unable to travel independently, and limited in furthering their education, this program aims to bridge the gap and create inclusive approaches to information access and strengthening inclusion among those with disabilities.

Another team focusing on visual impairment is led by Wichita State University, with collaborators at Kansas State University and Georgia Tech. In order to address national health and welfare, the team is fostering the formation of MABLE (Mapping for Accessibility in BuiLt Environments). The design is meant to allow those with visual and mobile impairments to navigate spaces through digital accessibility maps of indoor environments. Innovations such as these create vital opportunities for people with disabilities to foster daily practices of independence and develop new frameworks for quantifying economic benefits.

Other researchers in the Midwest are doing related work on visual accessibility. Professor JooYoung Seo serves as the Director of the Accessible Computing Lab in the School of Information Sciences at the University of Illinois at Urbana-Champaign (UIUC). “One of the ongoing projects in our lab is the development of an accessible data visualization system, particularly designed for blind and low-vision users,” Seo said. “This system leverages multimodalities like sound, speech, and braille to allow users to explore and analyze data. This project is of paramount importance, particularly in today’s digital era where data literacy is a crucial skill for everyone. By creating an accessible data visualization system, we are providing equitable access to visual information and contributing to data literacy for all individuals, regardless of their dis/abilities. This project illustrates our commitment to designing technology that is inclusive and supportive of everyone’s data needs.”

Seo also serves as senior personnel on the Delta high-performance computing (HPC) project, funded by NSF and led from the National Center for Supercomputing Applications at UIUC. Seo’s role involves identifying and addressing accessibility issues. “Our goal is to improve the interface to make it more inclusive for users with disabilities. The essence of this project lies in its potential to transform accessibility in the realm of high-performance computing. In a field where high efficiency and speed are paramount, we must also remember that true innovation should be accessible to all. Delta strives to break down barriers and create an environment that is equally beneficial and inclusive for all users, regardless of their abilities. This project underscores the principle that every user, regardless of their abilities, should be able to utilize technology with ease.”

The impact these projects have on people with disabilities is invaluable as well as for those who work in the field or plan to. Addison Graham is a fourth-year undergraduate student at Illinois State University (ISU) studying Special Education—Specialist in Low Vision and Blindness, with a Certificate in Early Intervention (SED w/ LVB Cert. in EI) and the president of ISU’s Braille Birds. The group is a registered student organization (RSO) that fosters education and spreads awareness about the blind and visually impaired community.

As an incoming educator in Special Education, Addison states,

            “With innovations like MABLE filling the need for greater ease-of-use navigational accessibility indoor of buildings, individuals with and without visual impairments could greatly benefit from the mandated reporting of a building’s interior design.”

Other teams receiving NSF awards under the Convergence Accelerator program include Michigan State University, Purdue University, and Northwestern University, which focus on projects for individuals who have speech impediments or are hearing impaired and create mobility independence for individuals with motor impairments. Projects such as these open opportunities to increase wellness and navigational accessibility for persons with disabilities.

To see a more in-depth description of each research project being conducted at various universities across the USA, see the table below.

Although the awardees each have different approaches and scopes of involvement of opportunities for persons with disabilities, there is a shared interest in synergizing work through facilitated collaboration in order to cultivate improved situations of development for marginalized populations. The Midwest Big Data Innovation Hub (MDBH) provides a venue for outreach and engagement that increases the potential for benefitting society and the themes seen with the institution’s awards. Collaborations with MDBH foster the use of data in developing solutions to enhance the quality of life and employment opportunities for persons with disabilities. These and other activities address topics that bring together diverse perspectives that open solutions for persons with disabilities.

Building a Climate Asset Map with the Midwest Climate Collaborative

By Sasha Zvenigorodsky

This story is part of a series on partnerships developed by the Midwest Big Data Innovation Hub with institutions across the Midwest through the Community Development and Engagement (CDE) Program.

Climate change—two words that have become increasingly popular throughout the scientific community as the world begins to see its destructive impacts across the globe. Though the rise in climate concerns for the future may appear to be a source of fear and uncertainty, many scholars, researchers, and academic organizations have regarded it as more of a call to action. This is where the Midwest Climate Collaborative (MCC) comes in.

Midwest Climate Collaborative Logo

The Midwest Climate Collaborative is headquartered at Washington University in St. Louis, Missouri, directed by Heather D. Navarro. This program is exclusive to a 12-state region in the Midwest and serves as a coordinating group for cross-sector responses to the ongoing climate crisis, with the objective of spreading knowledge about the issue as well as encouraging leadership and cross collaboration between various organizations to address the problem.

The MCC is a relatively new organization that was launched following the conclusion of a Think Tank series that was centered around outreach and engagement for climate action. By the end of the series, it was apparent that there is a plethora of great climate work being done across different institutions throughout the Midwest. Despite this, there are issues in their ability to connect and achieve collective success. Thus, participating Think Tank partners came together to craft strategies and objectives for the MCC, which was ultimately launched in January of 2022.

Throughout this past year, the MCC has established a variety of different strategic projects. One, launched in collaboration with the Midwest Big Data Innovation Hub (MBDH), is called the Climate Asset Map (CAM). This project has a goal of helping audiences such as researchers, practitioners, and community groups to easily access and contribute to climate action information that already exists in the region.

Currently, many governments and nongovernmental organizations (NGOs) local to the Midwest have limited resources to find and implement the latest climate research. The CAM serves to bridge this gap via an online, user-friendly interface. The assets of CAM could include data sets, research labs, training programs, and more. “Above all, I want this project to encourage people to invest in the Midwest,” says MCC Executive Director Heather Navarro.

As of now, the CAM group is moving forward in conducting a needs assessment survey with the help of a funded partnership with the MBDH. The needs assessment survey will help with the development of the CAM by determining which resources would be most beneficial for potential users to achieve success within their climate work. The survey results will be shared at the Midwest Climate Summit in February 2023, and will be distributed electronically over email and social media.

Although the fight against climate change is not an easy one, the MCC has worked as a catalyst to create a strong, interconnected Midwest region, which will certainly make it easier.

MBDH Partners on New Data Science Workshop for Underrepresented High School Students

By Aisha Tepede

This story is part of a series on partnerships developed by the Midwest Big Data Innovation Hub with institutions across the Midwest through the Community Development and Engagement (CDE) Program.

Deciding what to do after high school can be overwhelming. There are various academic and career options that are provided but many students may feel uncertain and unprepared to make those big decisions. In central Michigan, high school students from several rural towns have the opportunity to learn about data science concepts for future careers at a summer workshop cosponsored by Central Michigan University and the Midwest Big Data Innovation Hub (MBDH).

Central Michigan University (CMU) holds inclusivity as core to its mission. According to the CMU mission, vision and values site, the institution prides itself on inclusion, and the student body and faculty “thrive on student-centered education and fostering personal and intellectual growth to prepare students for productive careers, meaningful lives, and responsible citizenship in a global society.”

The university’s dedication to growth goes beyond its current students and into its larger local community. With the institution having a strong and historic relationship with the Saginaw Chippewa Indian Tribe, the partnership allows for the advancement and improvement of community members’ quality of life. With Native Americans being underrepresented at major points in the academic data science pipeline, it speaks volumes that the university is seeking collaboration to engage with high school students early in their career planning and help them understand potential career paths in data science.

After seeing the lack of programming geared toward at-risk high school students in the community, CMU faculty members, Dr. John E. Daniels and Dr. Mohamed Amezziane developed a proposal to create a data science workshop for high school students from underrepresented and tribal communities. Daniels and Amezziane stated, “We wish to target students who are unsure about their future but might not be considering college due to financial issues or uncertainty in a major. Often, these students come from underrepresented groups and are overlooked as potential university students.”

With support from the MBDH, CMU will partner with several high schools in rural central Michigan to offer a 5-day summer workshop at CMU, introducing approximately 35 rural and underrepresented high school students to data science. Participants, including student members of the local Ojibwa Tribe, will be recruited with the support and recommendations of their local high schools.

Upon completion of the workshop, students will be more familiar with data science, will analyze data using open-source statistical software (R), and will learn how to prepare and give a professional presentation summarizing their assigned research project. The context of the assigned learning modules and project will be on making healthy lifestyle choices (nutrition, alcohol/drugs). Data used in the workshop will come from selected sources, such as the National Health and Nutrition Examination Survey (NHANES). According to the website, NHANES is a resource that consists of demographic, socioeconomic, dietary, and health-related questions designed to assess the health and nutritional status of adults and children in the United States.

Central Michigan University’s Data Science program was started 18 months ago and is attempting to generate interest among the local student population. The flexibility and versatility of data science provide an opportunity to attract and recruit students who might not fit the typical college-prep template. Not only does the program hope to foster students’ interest in data science but the CMU Admissions staff will also offer assistance to students on how to apply to data science programs, fill out Free Application for Federal Student Aid (FAFSA) financial aid forms, and address possible application barriers that would prevent students from completing a successful admission application.

Through best practices and student feedback from this 5-day program being evaluated, there are plans to make this a yearly event. Overall, the university hopes to see an increase in the number of students pursuing Data Science as a major at CMU or other regional colleges and universities. In addition, by personalizing the data sets, Daniels believes the students will connect how using statistical software could be used to make better decisions in their own lives.

Our workshop will focus on making healthy lifestyle choices,” Daniels said. “Instead of preaching about smoking, drinking, or texting while driving, we hope to use data science as a vehicle to demonstrate the consequences of one’s lifestyle choices and at the same time learn about all of the tools and techniques data science has to offer. The methods we will be teaching can be applied to a variety of research questions and data sets. Perhaps this will inspire some students to recognize the value of data science and to pursue it in higher education.”

Dr. Jeff Inungu, CMU Professor and Director of the Master of Public Health Program, believes that by using the lens of public health and data science, “Experience and integrative learning offer students opportunities to gain skills that are highly desirable and prepare them to become leaders who are able to meet the ever-changing challenges of promoting, protecting, and enhancing the health of vulnerable communities.”

Regarding the long-term goals for the workshop, Daniels says, “Overall, the program will continue to focus on data science, reinforce the healthy lifestyle context, and gradually increase the number of workshop participants. The desired outcome is a steady increase in data science majors in our geographic area.”

When the workshop concludes, the team will work with the MBDH to assess the impact of the project and make resources available for faculty at other institutions to use in developing similar events on their campuses.

Data is the new science; it has the potential to answer the world’s problems if the right questions are asked. And some data science education programs are now focusing on working with local communities to help with real-world problems.

The Data Science for the Public Good (DSPG) Young Scholars Program is an immersive summer program that engages students from across Iowa to work together on projects that address social issues in the world today. Both graduate and undergraduate students are selected through a competitive statewide search. Graduate students (fellows) lead, support, and guide students together with Iowa State University (ISU) faculty and research associates, while undergraduate students (interns) acquire programming and statistical analysis experience through formal training and practical applications.

Working in teams, fellows and interns collaborate with project stakeholders and research faculty across disciplines. Research teams combine disciplines including statistics, data science, and the social and behavioral sciences to address complex problems proposed by local, state, and nonprofit agencies. Some of the program highlights for scholars include: expert training in tools for quantitative computing and data visualization (R, GIS, Tableau, etc.); professional training through workshops, seminars, and career talks; individualized mentors working closely with students; technical reporting and publication opportunities; and opportunities to interact with decision-makers in local communities, nonprofits, and state government agencies.

This past summer’s DSPG Program ran from May 23 to August 5. In light of COVID-19 and to accommodate non-ISU students, the program was held entirely online. Nonetheless, DSPG Scholars were provided the same opportunities to develop a professional portfolio, expand their networks, and learn about practical applications of data science to solving real-world problems. At the end of the summer, scholars got to present their research at the Annual DSPG Symposium. The symposium featured several distinguished keynote speakers and poster presentations by the Young Scholars. Final presentations for the 2022 DSPG Program were held on Thursday, August 4 via Zoom and recordings are available on ISU’s website.

The program is led every year by five land-grant universities and funded, in part, by the US Department of Agriculture (USDA) National Institute of Food and Agriculture (NIFA) to create a coalition for the public good. Christopher Seeger, one of the professors leading Iowa State’s program, said, “Ultimately, this is a community service. We let the community drive the conversation, while we listen to what they want and how we can help.” All of the projects were built upon a model called the Community Learning through Data Driven Discovery Process (CLD3), and helped local communities tackle real problems. Projects were incredibly diverse, with topics ranging from wholesale local food benchmarking to evaluating indicators for equal local housing needs to creating interactive commodity reports for agricultural marketing.

A webinar that further highlighted some of these projects and the DSPG Program was hosted by the Midwest Big Data Innovation Hub on October 27, 2022. Matthew Voss, Rural Policy Data Analyst for the Public Science Collaborative, featured a project from his summer as a graduate fellow where his team created analytics and dashboards to help a nonprofit organization, Eat Greater Des Moines (EGDM), more effectively target, locate, and expand food rescue in Central Iowa. Their client came to them because they had an abundance of data but did not know how to use it to answer crucial questions posed by their board, such as where people are experiencing the most food insecurity, which distribution sites have the greatest losses due to food waste, etc. This is where the DSPG Scholars stepped in. For their project, the students cleaned the large data sets and then used them to develop sustainable pipelines in Google Sheets and Google Data Studio that visually answered EGDM’s questions through interactive dashboards. The project is now published on the nonprofit organization’s website, where the DSPG team is directly credited for all of their work.

Voss’s project was just one example of how the DSPG Young Scholars Program is making a positive impact on the community while also teaching students valuable data science skills. Two other DSPG fellows, Kelsey Van Selous and Harun Çelik, also presented their projects on the webinar. Dr. Cassandra Dorius, Associate Professor of Human Development and Family Studies, and a founding co-director of the DSPG Program, said, “Students were very creative and motivated, and produced great analytics and projects. We are excited to see how this work improves people’s lives moving forward.”

Physics-Based Machine Learning for Sub-Seasonal Climate Forecasting

By Raleigh Butler

We’ve all heard the old adage that if you don’t like the weather in the Midwest, wait a minute and it will change. So how can we possibly forecast conditions weeks in advance?

In 2019, an NSF collaborative grant was awarded to six institutions to sponsor the study of sub-seasonal climate forecasting (SSF)—with machine learning (ML). This topic addresses three core themes of the Midwest Big Data Innovation Hub—resilient communities, digital agriculture, and cyberinfrastructure. A project of the NSF Harnessing the Data Revolution (HDR) program, this award was to researchers at the following six universities: University of Minnesota–Twin Cities, University of Chicago, University of Wisconsin–Madison, Carnegie Mellon University, George Mason University, and the University of Illinois at Urbana-Champaign.

What is Sub-Seasonal Climate Forecasting?

Sub-seasonal climate forecasting focuses on predicting weather 2–8 weeks away. Interestingly, this is an area of higher difficulty than other types of forecasting. As the research team states on its website, “SSF is considered more challenging than either weather forecasting or even seasonal forecasting.” This effort ties ML together with agriculture in an effort to make these difficult predictions.

Computing’s Place in Forecasting

What is ML compared with deep learning (DL)? Machine learning builds methods for machines to “learn” or change their procedures based on input over time. Deep learning is a specific type of ML and is based on how the human brain operates.

In the linked article below from the SSF team, some difficulties in building models are discussed. Many of these difficulties are tied to the relationship between ML and physics. Therefore, systems have been created for physics-guided ML and ML-enhanced physics. Here’s what some of these systems take into account to overcome the difficulties:

  • • Physics-guided ML takes physics into account to produce output (such as forces affecting movement of clouds, gravity in rainfall, etc.). Unfortunately, existing data that includes physics-related information is limited.
  • • The other approach is ML-enhanced physics. One example of this, among many, is the Monte Carlo Tree Search (MCTS). The MCTS works by applying a hierarchical partition tree to the data. By using this approach, the program follows the sub-“branches” that are most likely in a given situation to produce a prediction. In short, the MCTS works as a decision tree and is optimized to predict the most likely path down each branch with each decision. A visual is provided in the image below.

Sub-Seasonal Agriculture

How does this tie into agriculture? First, we will examine the key planning that takes place during sub-seasonal periods. According to a graph on the SSF project site, these are some important decisions that are made during those periods:

  • Maritime Planning: Designate ship routing
  • Agriculture: Schedule planting
  • Agriculture: Irrigate and apply nutrients
  • Emergency Management: Pre-stage emergency supplies
  • Aviation: Plan evacuations and sorties
  • Water Resources: Manage reservoir levels for flood control
  • Energy: Plan for spikes in energy demand

Making these decisions is a delicate process; there is a high price to pay if predictions are incorrect. Increasing the ability to accurately forecast sub-seasonally is, of course, monetarily valuable; however, it is also valuable in terms of product production and delivery.

These studies have resulted in several scientific publications since the conclusion of the funding. One of these papers, published by many team members of the original study, is published here (available for download as a pdf). The paper, published in June 2020, discusses challenges, analyses, and advances associated with ML climate forecasting. The paper includes several diagrams of how various models predict sub-seasonal weather differently. The models also discuss forecasting in various climate zones (over the ocean, and different areas over land).

Scientists are still collecting data to use as input for the models and to increase accuracy. As mentioned, this area of forecasting is more difficult than forecasting over time horizons that are nearer or further away. Although climate prediction may still be difficult, there is progress being made in the field. The paper mentioned above states, “Overall, XGBoost and Encoder (LSTM)-Decoder (FNN) perform the best. Qualitatively, coastal and south regions are easier to predict than inland regions (e.g., Midwest).”

University of Nebraska researchers extend smart rural bridge health initiatives

By Raleigh Butler

Did you know that, despite increases in technology, bridge health across the United States is decreasing? Bridges currently score a C on the country’s infrastructure report card, which is a fall from last year’s grade.

Within the Midwest, the percentage of structurally deficient bridges per state include the following:

  • • Iowa has the largest percentage, 19.0%.
  • • Minnesota has the smallest percentage, 4.7%.

The Midwest Big Data Innovation Hub’s Smart & Resilient Communities priority area spans a range of disciplines, sectors, data, and cyberinfrastructure in its work to connect researchers and practitioners focused on community resilience. Bridges play key roles in community planning, resilient supply chains for food and goods, and in transportation capacity management.

Foundations

In 2018, a new regional innovation center project, “Smart Big Data Pipeline for Aging Rural Bridge Transportation Infrastructure (SMARTI),” was funded by a $1 million National Science Foundation (NSF) grant. The grant was aimed toward “rural bridge health management” and included faculty from both the University of Nebraska–Lincoln (UNL) and University of Nebraska Omaha (UNO). The work began with a planning grant in 2016, and both awards were part of the NSF’s Big Data Spoke program, in collaboration with the regional Big Data Innovation Hub program.

The principal investigator for the project, Robin Gandhi, is from UNO’s College of Information Science and Technology. The 16 research team members also include Daniel Linzell and Chungwook Sim, both from UNL’s College of Engineering.

The SMARTI project focused on “mining existing data sets from private, state and federal partners, as well as collect[ing] new data through sensors on targeted rural bridges throughout Nebraska.” The outputs of this work were presented through workshops and made available to researchers through the Bridging Big Data website.

“Our government and industry partners can better manage their aging rural bridges, improve their health and ultimately keep people safe using data and tools developed from our research,” said Robin Gandhi. “We continue to engage stakeholders through companion research projects and by presenting our work at relevant technical meetings and conferences. For example, we will be presenting at the Midwest Bridge Preservation Partnership, the American Society of Civil Engineers Structures Congress in April, and the International Association for Bridge Management and Safety Conference in July 2022.”

Student engagement

Six students from both the Lincoln and Omaha campuses who are working on these projects presented their research in October 2021 at the Midwest Big Data Innovation Hub’s Regional Community Meeting, with a focus on the data sets and data science tools that are important to this work. Recordings of their presentations are available on the MBDH YouTube channel.

Next steps

Approximately three years after the start of the SMARTI project, the Nebraska team was awarded $5 million by the Department of Defense Army Corps of Engineers for research to extend the lifespan of bridges through new monitoring technology. This award was announced in October 2021.

The researchers will continue with their work on bridge safety. The team will use rural Nebraska as testbeds for locations to safely collect data, as well as to analyze “socio-technical impacts such as fairness of data, algorithms, and analysis; and intelligent decision-making and support systems.”

“This project brings bridge owners, designers, and builders, big data solution providers, and academics together to discuss data-informed bridge infrastructure health and resilience in times of crisis,” said Daniel Linzell. “Attendees at our last workshop heard from several stakeholders about the pandemic’s impact on bridge infrastructure resilience from design, sensing, economic, and socio-political perspectives. Discussions such as these keep the research team focused on the importance of the work: developing sensing and big data technology applications that support smart, resilient, big data pipelines for aging rural bridge transportation infrastructure; highlighting solutions to data discovery and controlled sharing challenges; and unveiling novel data-driven decision-making tools.”

Professor Kimberly Zarecor on Community-Based Research and Building Interdisciplinary Research Teams

By Qining Wang

An expert in Eastern European Architecture, Professor Kimberly Zarecor tells us about her journey of building a highly interdisciplinary research team that takes data science into research on rural communities in Iowa.

Kimberly Zarecor

To some, architectural history and data science research may sound like oil and water—two fields that are almost impossible to mix well. However, Kimberly Zarecor, professor of Architecture at Iowa State University (ISU), leads her research team to create the perfect emulsion of many seemingly unrelated fields: sociology, statistics, industrial design, data science, architecture, and beyond.

With a research focus on small and shrinking communities in rural Iowa, not only does the team uncover the community efforts that keep some of these towns thriving, but the team is also offering the broader research community a valuable lesson on how to bring a wide range of expertise to projects and how experts from different fields can work together in harmony.

Zarecor found her inspiration to study Iowa’s shrinking towns from Ostrava, in the Czech Republic, a city she studied during her PhD research and later lived in for a semester as a Fulbright scholar. “[Ostrava] was part of a study in Europe called the Shrink Smart project, where [researchers] were looking at Ostrava as a shrinking post-industrial European city and questioned how to manage the governance of a relatively large city in the context of population loss.” As Zarecor shifted her primary research focus from architectural history in Eastern European cities to rural population loss in the Midwest, she realized the concept of shrinking smart could also be applied.

Zarecor and her collaborators started exploring the data-science component of shrinking smart with funding from a Smart & Connected Communities planning grant from the National Science Foundation (NSF) in 2017. Researchers at Iowa State University have been collecting data about the quality of life in small Iowa towns through the Iowa Small Town Poll since 1994, but “nobody had ever brought a data-science mindset to the analysis of [this] data.” The sociologists who had been collecting the data did not “think of [the poll] as a large set” and had not thought to build “a predictive model” from it.

Zarecor invited a computer scientist to be part of the planning grant team to transform the Small Town Poll data into training data, from which they could construct models to understand and predict the factors that influence people’s perceptions of quality of life in small rural communities. “We realized that what we were trying to understand is what are the actions that people in communities take as inputs into a system that results as outputs on the other side, as increases in perceptions of quality of life,” Zarecor explained. The planning grant team, consisting of a computer scientist, a sociologist, a community and regional planner, and two architects, found that “the best way to define [rural smart shrinkage] is that you are actively pursuing specific activities that you as a community can do together” that contribute to improved perceptions of quality of life even as population loss continues.

In 2020, Zarecor received another NSF grant of $1.5 million to continue this research and investigate strategies to address the data deficit in shrinking rural communities.

As the scope of the research expanded, so has Zarecor’s team. In addition to Zarecor and rural sociologist David Peters, who was also a Co-PI on the planning grant, the team now includes a community economic development specialist and a community arts specialist from ISU Extension and Outreach (both are also faculty in the College of Design at Iowa State), an industrial design faculty member, masters students from industrial design and community and regional planning, and for the data science work, three statistics faculty and three statistics PhD students. The Iowa League of Cities is also a partner on the project.

Coming to data science with little technical understanding, Zarecor approaches the data science component more from an intuitive rather than conceptual perspective: “It’s not that I understand the statistics, but I understand [the goals] as we go step by step . . . [and] the power of the tools that [the statisticians] are building.”

To lead such a highly interdisciplinary team, Zarecor thinks of herself as a bridge-builder within the team. Zarecor helps the members of her team understand data science by asking questions in a way that they can elicit responses that deepen the understandings of the nontechnical team members. “I like having that [bridge] function because it’s asking questions as a way of learning. For me, just the conversations with the data scientists helped me to better understand the data science part of our project.”

And the bridge function goes both ways. In addition to helping non-data-science experts learn more about the potential of data science, Zarecor also cultivates data scientists’ ability to contribute to projects that are community-based. “When it comes to community-based work, the assumption that this is not an expertise of its own is something that’s a challenge for the field, because doing work in communities is its own expertise,” Zarecor explained. Even though the residents in rural Iowa are the direct beneficiaries of the work from Zarecor’s team, the knowledge gap with respect to finding and using data makes those benefits inaccessible to some residents. Meanwhile, data scientists often lack the skills to convey their findings to an audience outside their academic circle. “As a field, data science, in my opinion, has not done a good job to educate necessarily well-rounded [data scientists].”

To overcome this bottleneck, Zarecor’s team works on creating dashboards that visualize the data and make the data more interpretable to the rural communities. Zarecor also encourages the statisticians on her team to talk to residents of the communities they study and ask what kind of data they would like to have. “When we ask what they want, it’s not because they know everything that’s available. We’re doing a mix of hearing from them what they want, and also guessing some things that they probably don’t know are out there that we can also give them in a usable form.”

Zarecor believes that similar types of highly collaborative and interdisciplinary research would benefit the entire research community, and those collaborations start with abandoning assumptions of different fields.

She gives an example in the discipline of architecture, where architects would assume themselves to be capable of doing graphic design or planning. Many don’t realize that those tasks are outside of their expertise even though these fields are seemingly adjacent. “And I would transfer that over to data scientists who know that data science is a synthetic and integrative discipline. [. . .] It doesn’t mean, though, that there are not all of these soft skills, all of this other communication, and people-related aspects of the data science work that you can handle without help.”

Therefore, Zarecor suggests that data scientists should work in conjunction with domain experts to make their research more relatable to a broader audience. Team members also need to respect the importance and specificity of other kinds of expertise beyond the technical or data-driven parts of a project. When a team successfully works this way, “the data science gets improved and amplified and becomes more useful. If you actually think horizontally on the project, you know that there’s not a pyramid, but that you are a team that’s working across the group [of collaborators]. This would be a much healthier way of [working with] data and for data scientists to interact with people.”

In this regard, Zarecor noted that the Midwest Big Data Innovation Hub, as a highly integrated and inclusive organization, has the potential to cultivate different layers of collaboration across various disciplines. “But it does require the data scientists who were the first audience, or the more explicit audience [for the Hub], to be willing to open up.”

How Do Scientists Help AI Cope with a Messy Physical World?

By Qining Wang

When we see a stop sign at an intersection, we won’t mistake it for a yield sign. Our eyes recognize the white “STOP” letters printed on the red hexagon. It doesn’t matter if the sign is under sunlight or streetlight. It doesn’t matter if a tree branch gets in the way or someone puts graffiti and stickers on the sign. In other words, our eyes can perceive objects under different physical conditions.

However, identifying road signs accurately is very different, if not more difficult, for artificial intelligence (AI). Even though, according to Alan Turning, AIs are systems that can “think like humans,” they can still present limitations in mimicking the human mind, depending on how they acquire their intelligence.

One of the potential hurdles is to correctly interpret variations in the physical environment. Such a limitation is commonly referred to as an “adversarial example.”

What Are Adversarial Examples?

Currently, the most common method to train an AI application is machine learning, a type of AI process that helps AI systems learn and improve from experience. Machine learning is like the driving class an AI needs to take before it can hit the road. Yet machine-learning-trained AIs are not immune to adversarial examples.

Circling back to reading the stop sign, an adversarial example could be the stop sign turning into a slightly darker shade of red at night. The machine-learning model captures these tiny color differences that human eyes cannot discern and might interpret the signs as something else. Another adversarial example could be a spam detector that fails to filter a spam email formatted like a normal email.

Just like how unpredictable individual human minds can be, it is also difficult to pinpoint the exact origin of what and why machine learning makes certain predictions. Neither is it a simple task to develop a machine-learning model that comprehends the messiness of a physical world. To improve the safety of self-driving cars and the quality of spam filters, data scientists are continuously tackling the vulnerabilities in the machine-learning processes that help AI applications “see” and “read” better.

What Are Humans Doing to Correct AI’s Mistakes?

To defend against adversarial examples, the most straightforward mechanism is to let machine-learning models analyze existing adversarial examples. For example, to help the AI of a self-driving car to recognize stop signs under different physical circumstances, we could expose the machine-learning model that controls the AI to pictures of stop signs under different lightings or at various distances and angles.

Google’s reCAPTCHA service is an example of such a defense. As an online safety measure, users need to click on images of traffic lights or road signs from a selection of pictures to prove that they are humans. What users might not be aware of is that they are also teaching the machine-learning model what different objects look like under different circumstances at the same time.

Alternatively, data scientists can improve AI by teaching them simulated adversarial examples during the machine-learning process. One way is to implement a Generative Adversarial Network (GAN).

GANs consist of two components: a generator and a discriminator. The generator “translates” a “real” input image from the training set (clean example) into an almost indistinguishable “fake” output image (adversarial example) by introducing random variations to the image. This “fake” image is then fed to the discriminator, where the discriminator tries to tell the modified and unmodified images apart.

The generator and the discriminator are inherently in competition: The generator strives to “fool” the discriminator, while the discriminator attempts to see through all its tricks. This cycle of fooling and being fooled repeats. Both become better at their own designated tasks over time. The cycle continues until the generator outcompetes the discriminator, creating adversarial examples that are indistinguishable to the discriminator. In the end, the generator is kept to defend against different types of real-life adversarial attacks.

AI Risks and Responses

GANs can be valuable tools to tackle adversarial examples in machine learning, but they can also serve malicious purposes. For instance, one other common application of GANs is face generation. This so-called “deepfake” makes it virtually impossible for humans to tell a real face from a GAN-generated face. Deepfakes could result in devastating consequences, such as corporate scams, social media manipulation, identity theft, or disinformation attacks, to name a few.

This shows how, as our physical lives become more and more entangled with our digital presence, we can never neglect the other side of the coin while enjoying the benefits brought to us by technological breakthroughs. Understanding both would serve as a starting point for practicing responsible AI principles and creating policies that enforce data ethics.

Tackling vulnerabilities in machine learning matters, and so does protecting ourselves and the community from the damage that those technologies could cause.

Guest post – Diverse programs from ISU address sustainable cities challenges

By Iowa State University’s Sustainable Cities team

Researchers with the Sustainable Cities team at Iowa State University recognize the difficulty that public officials face in transforming vast amounts of climate and energy research into contextualized public policy. In attempting to address this critical issue, the team’s mission goes beyond the creation of new climate analysis tools to also investigate new methods for integrating communities into the discourse of data creation and energy conservation. To accomplish this agenda, our team engages in various research avenues that range from the creation of new spatial-data tools to enabling community youth activism. Here are just a few highlights of the team’s most recent achievements:

Sustainable Cities’ team leader Ulrike Passe, associate professor of architecture, presented our hybrid physics data modeling framework at the National Science Foundation-sponsored Research Coordination Networking (RCN) workshop held at Carnegie Mellon University on May 17, 2018. The presentation, which capstones one of the major branches of the Sustainable Cities initiatives, demonstrated the integration of our recently developed thermo-physical data simulator with our research into human energy-use behavior to demonstrate how a more holistic neighborhood energy model could be constructed. This same model was presented by graduate research assistant Himanshu Sharma at the fifth High Performance Building’s Conference on July 9, 2018, at Purdue University.

The Community Growers Program, a public-engagement initiative started back in March of 2017, has become another core pillar of the Sustainable Cities group research. Spanning a course of eight weeks, researchers worked with 22 leadership-minded youth in the Baker Chapter of the Boys and Girls Club at Hiatt Middle School in Des Moines, Iowa, to create a community garden based on a methodology of spatial, socio-technical storytelling. Through this process, the youth participants were able to learn more about their community through access to geographic information system (GIS) and spatial mapping tools. Associate English professor Linda Shenk, our community engagement lead, and Mallory Riesberg, a collaborator with the Baker Chapter of the Boys and Girls Club, presented this methodology in a presentation titled, “Fostering the Next Generation of Big Data Scientists and Sustainable City Planners” at The Growing Sustainable Communities Conference in Dubuque, Iowa, on Oct. 4, 2017. Team members Linda Shenk, Passe and Alenka Poplin, assistant professor of community and regional planning, would later be published in the 35th Journal of Interaction Design and Architectures for the inclusion of this work in their entry, titled, Engaging Youth with Pervasive Technologies for Resilient Communities.

Poplin, an established researcher in the field of geo-spatial mapping, also leads a research group that seeks to understand how to better develop feedback loops through innovative user-interfaces. An inquiry into mapping places of emotional power was highlighted in a 2017 paper entry to the second edition of Kartographische Nachrichten on Empirical Cartography Journal, titled, “Mapping Expressed Emotions: Empirical Experiments on Power Places.” More recently, Poplin and her researcher team have begun testing an energy survey game they have developed called E-Footprints. The framework of this game includes the extraction of user-performance data to measure and analyze what learning opportunities may help guide more environmentally efficient decision making. This feedback is then generated back into learning mini-games throughout the game, such that the user gets more “energy savvy” as they play. This project begins field-testing in November 2018.

With a diverse, multifaceted research team of nearly 50 members, the Sustainable Cities group continues to advance the capabilities of communities and cities to think sustainably about a better future.
