Big Data Analysis: New Algorithms for a New Society

Curated on December 30, 2015August 3, 2018 by Stefaan Verhulst

Book edited by Nathalie Japkowicz and Jerzy Stefanowski: “This edited volume is devoted to Big Data Analysis from a Machine Learning standpoint as presented by some of the most eminent researchers in this area.

It demonstrates that Big Data Analysis opens up new research problems which were either never considered before, or were only considered within a limited range. In addition to providing methodological discussions on the principles of mining Big Data and the difference between traditional statistical data analysis and newer computing frameworks, this book presents recently developed algorithms affecting such areas as business, financial forecasting, human mobility, the Internet of Things, information networks, bioinformatics, medical systems and life science. It explores, through a number of specific examples, how the study of Big Data Analysis has evolved and how it has started and will most likely continue to affect society. While the benefits brought upon by Big Data Analysis are underlined, the book also discusses some of the warnings that have been issued concerning the potential dangers of Big Data Analysis along with its pitfalls and challenges….(More)”

Smarter as the New Urban Agenda

Curated on December 15, 2015August 3, 2018 by Stefaan Verhulst

New book edited by Gil-Garcia, J. Ramon, Pardo, Theresa A., Nam, Taewoo: “This book will provide one of the first comprehensive approaches to the study of smart city governments with theories and concepts for understanding and researching 21st century city governments innovative methodologies for the analysis and evaluation of smart city initiatives. The term “smart city” is now generally used to represent efforts that in different ways describe a comprehensive vision of a city for the present and future. A smarter city infuses information into its physical infrastructure to improve conveniences, facilitate mobility, add efficiencies, conserve energy, improve the quality of air and water, identify problems and fix them quickly, recover rapidly from disasters, collect data to make better decisions, deploy resources effectively and share data to enable collaboration across entities and domains. These and other similar efforts are expected to make cities more intelligent in terms of efficiency, effectiveness, productivity, transparency, and sustainability, among other important aspects. Given this changing social, institutional and technology environment, it seems feasible and likeable to attain smarter cities and by extension, smarter governments: virtually integrated, networked, interconnected, responsive, and efficient. This book will help build the bridge between sound research and practice expertise in the area of smarter cities and will be of interest to researchers and students in the e-government, public administration, political science, communication, information science, administrative sciences and management, sociology, computer science, and information technology. As well as government officials and public managers who will find practical recommendations based on rigorous studies that will contain insights and guidance for the development, management, and evaluation of complex smart cities and smart government initiatives….(More)”

The Moral Failure of Computer Scientists

Curated on December 15, 2015August 3, 2018 by Stefaan Verhulst

Kaveh Waddell at the Atlantic: “Computer scientists and cryptographers occupy some of the ivory tower’s highest floors. Among academics, their work is prestigious and celebrated. To the average observer, much of it is too technical to comprehend. The field’s problems can sometimes seem remote from reality.

But computer science has quite a bit to do with reality. Its practitioners devise the surveillance systems that watch over nearly every space, public or otherwise—and they design the tools that allow for privacy in the digital realm. Computer science is political, by its very nature.

That’s at least according to Phillip Rogaway, a professor of computer science at the University of California, Davis, who has helped create some of the most important tools that secure the Internet today. Last week, Rogaway took his case directly to a roomful of cryptographers at a conference in Auckland, New Zealand. He accused them of a moral failure: By allowing the government to construct a massive surveillance apparatus, the field had abused the public trust. Rogaway said the scientists had a duty to pursue social good in their work.
He likened the danger posed by modern governments’ growing surveillance capabilities to the threat of nuclear warfare in the 1950s, and called upon scientists to step up and speak out today, as they did then.

I spoke to Rogaway about why cryptographers fail to see their work in moral terms, and the emerging link between encryption and terrorism in the national conversation. A transcript of our conversation appears below, lightly edited for concision and clarity….(More)”

Stretching science: why emotional intelligence is key to tackling climate change

Curated on December 15, 2015August 15, 2018 by Stefaan Verhulst

Faith Kearns at the Conversation: “…some environmental challenges are increasingly taking on characteristics of intractable conflicts, which may remain unresolved despite good faith efforts.

In the case of climate change, conflicts ranging from debates over how to lower emissions to denialism are obvious and ongoing -– the science community has often approached them as something to be defeated or ignored.

While some people love it and others hate it, conflict is often an indicator that something important is happening; we generally don’t fight about things we don’t care about.

Working with conflict is a challenging proposition, in part because while it manifests in interactions with others, much of the real effort comes in dealing with our own internal conflicts.

However, beginning to accept and even value conflict as a necessary part of large-scale societal transformation has the potential to generate new approaches to climate change engagement. For example, understanding that in some cases denial by another person is protective may lead to new approaches to engagement.

As we connect more deeply with conflict, we may come to see it not as a flame to be fanned or put out, but as a resource.

A relational approach to climate change

Indeed, because of the emotion and conflict involved, the concept of a relational approach is one that offers a great deal of promise in the climate change arena. It is, however, vastly underexplored.

Relationship-centered approaches have been taken up in law, medicine, and psychology.

A common thread among these fields is a shift from expert-driven to more collaborative modes of working together. Navigating the personal and emotional elements of this kind of work asks quite a bit more of practitioners than subject-matter expertise.

In medicine, for example, relationship-centered care is a framework examining how relationships – between patients and clinicians, among clinicians, and even with broader communities – impact health care. It recognizes that care may go well beyond technical competency.

This kind of framework can demonstrate how a relational approach is different from more colloquial understandings of relationships; it can be a way to intentionally and transparently attend to conflict and power dynamics as they arise.

Although this is a simplified view of relational work, many would argue that an emphasis on emergent and transformative properties of relationships has been revolutionary. And one of the key challenges, and opportunities, of a relationship-centered approach to climate work is that we truly have no idea what the outcomes will be.

We have long tried to motivate action around climate change by decreasing scientific uncertainty, so introducing social uncertainty feels risky. At the same time it can be a relief because, in working together, nobody has to have the answer.

Learning to be comfortable with discomfort

A relational approach to climate change may sound basic to some, and complicated to others. In either case, it can be useful to know there is evidence that skillful relational capacity can be taught and learned.

The medical and legal communities have been developing relationship-centered training for years.

It is clear that relational skills and capacities like conflict resolution, empathy, and compassion can be enhanced through practices including active listening and self-reflection. Although it may seem an odd fit, climate change invites ability to work together in new ways that include acknowledging and working with the strong emotions involved.

With a relationship-centered approach, climate change issues become less about particular solutions, and more about transforming how we work together. It is both risky and revolutionary in that it asks us to take a giant leap into trusting not just scientific information, but each other….(More)”

China’s Biggest Polluters Face Wrath of Data-Wielding Citizens

Curated on December 14, 2015May 29, 2019 by Stefaan Verhulst

Bloomberg News: “Besides facing hefty fines, criminal punishments and the possibility of closing, the worst emitters in China risk additional public anger as new smartphone applications and lower-cost monitoring devices widen access to data on pollution sources.

The Blue Map app, developed by the Institute of Public & Environmental Affairs with support from the SEE Foundation and the Alibaba Foundation, provides pollution data from more than 3,000 large coal-power, steel, cement and petrochemical production plants. Origins Technology Ltd. in July began sale of the Laser Egg, a palm-sized air quality monitor used to track indoor and outdoor air quality by measuring fine particulate matter in the air.

“Letting people know the sources of regional pollution will help the push for control over emissions of every chimney,” said Ma Jun, the founder and director of the Beijing-based IPE.

The phone map and Laser Egg are the latest levers in prying control over information on air quality from the hands of the few to the many, and they’re beginning to weigh on how officials respond to the issue. Numerous smartphone applications, including those developed by SINA Corp. and Moji Fengyun (Beijing) Software Technology Development Co., now provide people in China with real-time access to air quality readings, essentially democratizing what was once an information pipeline available only to the government.

“China’s continuing struggle to control and reduce air pollution exemplifies the government’s fear that lifestyle issues will mutate into demands for political change,” said Mary Gallagher, an associate professor of political science at the University of Michigan.

Even the government is getting in on the act. The Ministry of Environmental Protection rolled out a smartphone application called “Nationwide Air Quality” with the help ofWuhan Juzheng Environmental Science & Technology Co. at the end of 2013.

“As citizens know more about air pollution, more pressure will be put on the government,” said Xu Qinxiang, a technology manager at Wuhan Juzheng. “This will urge the government to control pollutant sources and upgrade heavy industries.”

Laser Egg

Sources of air quality data come from the China National Environment Monitoring Center, local environmental protection bureaus and non-Chinese sources such as the U.S. Embassy’s website in Beijing, Xu said.

Air quality is a controversial subject in China. Since 2012, the public has pushed the government to move more quickly than planned to begin releasing data measuring pollution levels — especially of PM2.5, the particulates most harmful to human health.

The reading was 267 micrograms per cubic meter at 10 a.m. Monday near Tiananmen Square, according to the Beijing Municipal Environmental Monitoring Center. The World Health Organization cautions against 24-hour exposure to concentrations higher than 25.

The availability of data appears to be filling a need, especially with the arrival of colder temperatures and the associated smog that blanketed Beijing and northern Chinarecently….

“With more disclosure of the data, everyone becomes more sensitive, hoping the government can do something,” Li Yajuan, a 27-year-old office secretary, said in an interview in Beijing’s Fuchengmen area. “It’s our own living environment after all.”

Efforts to make products linked to air data continue. IBM has been developing artificial intelligence to help fight Beijing’s toxic air pollution, and plans to work with other municipalities in China and India on similar projects to manage air quality….(More)”

Big Data Before the Web

Curated on December 14, 2015August 3, 2018 by Stefaan Verhulst

Evan Hepler-Smith in the Wall Street Journal: “Sometime in the early 1950s, on a reservation in Wisconsin, a Menominee Indian man looked at an ink blot. An anthropologist recorded the man’s reaction according to a standard Rorschach-test protocol. The researcher submitted a copy of these notes to an enormous cache of records collected over the course of decades by American social scientists working among various “societies ‘other than our own.’ ” This entire collection of social-scientific data was photographed and printed in arrays of microscopic images on 3-by-5-inch cards. Sets of these cards were shipped to research libraries around the world. They gathered dust.

In the results of this Rorschach test, the anthropologist saw evidence of a culture eroded by modernity. Sixty years later, these documents also testify to the aspirations and fate of the social-scientific project for which they were generated. Deep within this forgotten Ozymandian card file sits the Menominee man’s reaction to Rorschach card VI: “It is like a dead planet. It seems to tell the story of a people once great who have lost . . . like something happened. All that’s left is the symbol.”

In “Database of Dreams: The Lost Quest to Catalog Humanity,” Rebecca Lemov delves into the ambitious efforts of mid-20th-century social scientists to build a “capacious and reliable science of the varieties of the human being” by generating an archive of human experience through interviews and tests and by storing the information on the high-tech media of the day.

For these psychologists and anthropologists, the key to a universal human science lay in studying members of cultures in transition between traditional and modern ways of life and in rendering their individuality as data. Interweaving stories of social scientists, Native American research subjects and information technologies, Ms. Lemov presents a compelling account of “what ‘humanness’ came to mean in an age of rapid change in technological and social conditions.” Ms. Lemov, an associate professor of the history of science at Harvard University, follows two contrasting threads through a story that she calls “a parable for our time.” She shows, first, how collecting data about human experience shapes human experience and, second, how a high-tech data repository of the 1950s became, as she puts it, a “data ruin.”…(More) – See also: Database of Dreams: The Lost Quest to Catalog Humanity

Data Science ethics

Curated on December 13, 2015August 3, 2018 by Stefaan Verhulst

Gov.uk blog: “If Tesco knows day-to-day how poorly the nation is, how can Government access similar insights so it can better plan health services? If Airbnb can give you a tailored service depending on your tastes, how can Government provide people with the right support to help them back into work in a way that is right for them? If companies are routinely using social media data to get feedback from their customers to improve their services, how can Government also use publicly available data to do the same?

Data science allows us to use new types of data and powerful tools to analyse this more quickly and more objectively than any human could. It can put us in the vanguard of policymaking – revealing new insights that leads to better and more tailored interventions. And it can help reduce costs, freeing up resource to spend on more serious cases.

But some of these data uses and machine-learning techniques are new and still relatively untested in Government. Of course, we operate within legal frameworks such as the Data Protection Act and Intellectual Property law. These are flexible but don’t always talk explicitly about the new challenges data science throws up. For example, how are you to explain the decision making process of a deep learning black box algorithm? And if you were able to, how would you do so in plain English and not a row of 0s and 1s?

We want data scientists to feel confident to innovate with data, alongside the policy makers and operational staff who make daily decisions on the data that the analysts provide –. That’s why we are creating an ethical framework which brings together the relevant parts of the law and ethical considerations into a simple document that helps Government officials decide what it can do and what it should do. We have a moral responsibility to maximise the use of data – which is never more apparent than after incidents of abuse or crime are left undetected – as well as to pay heed to the potential risks of these new tools. The guidelines are draft and not formal government policy, but we want to share them more widely in order to help iterate and improve them further….

So what’s in the framework? There is more detail in the fuller document, but it is based around six key principles:

Start with a clear user need and public benefit: this will help you justify the level of data sensitivity and method you use
Use the minimum level of data necessary to fulfill the public benefit: there are many techniques for doing so, such as de-identification, aggregation or querying against data
Build robust data science models: the model is only as good as the data it contains and while machines are less biased than humans they can get it wrong. It’s critical to be clear about the confidence of the model and think through unintended consequences and biases contained within the data
Be alert to public perceptions: put simply, what would a normal person on the street think about the project?
Be as open and accountable as possible: Transparency is the antiseptic for unethical behavior. Aim to be as open as possible (with explanations in plain English), although in certain public protection cases the ability to be transparent will be constrained.
Keep data safe and secure: this is not restricted to data science projects but we know that the public are most concerned about losing control of their data….(More)”

Big Data in the Policy Cycle: Policy Decision Making in the Digital Era

Curated on December 10, 2015August 3, 2018 by Stefaan Verhulst

Paper by Johann Höchtl et al in the Journal of Organizational Computing and Electronic Commerce: “Although of high relevance to political science, the interaction between technological change and political change in the era of Big Data remains somewhat of a neglected topic. Most studies focus on the concept of e-government and e-governance, and on how already existing government activities performed through the bureaucratic body of public administration could be improved by technology. This paper attempts to build a bridge between the field of e-governance and theories of public administration that goes beyond the service delivery approach that dominates a large part of e-government research. Using the policy cycle as a generic model for policy processes and policy development, a new look on how policy decision making could be conducted on the basis of ICT and Big Data is presented in this paper….(More)”

Five Studies: How Behavioral Science Can Help in International Development

Curated on December 9, 2015August 3, 2018 by Stefaan Verhulst

Dwyer Gunn in Pacific Standard: “In 2012, there were 896 million people around the world—12.7 percent of the global population—living on less than two dollars a day. The World Food Programestimates that 795 million people worldwide don’t have enough food to “lead a healthy life”; 25 percent of people living in Sub-Saharan Africa are undernourished. Over three million children die every year thanks to poor nutrition, and hunger is the leading cause of death worldwide. In 2012, just three preventable diseases (pneumonia, diarrhea, and malaria) killed 4,600 children every day.

Last month, the World Bank announced the launch of the Global Insights Initiative (GINI). The initiative, which follows in the footsteps of so-called “nudge units” in the United Kingdom and United States, is the Bank’s effort to incorporate insights from the field of behavioral science into the design of international development programs; too often, those programs failed to account for how people behave in the real world. Development policy, according to the Bank’s 2015 World Development Report, is overdue for a “redesign based on careful consideration of human factors.” Researchers have applauded the announcement, but it raises an interesting question: What can nudges really accomplish in the face of the developing world’s overwhelming poverty and health-care deficits?

In fact, researchers have found that instituting small program changes, informed by a better understanding of people’s motivations and limitations, can have big effects on everything from savings rates to vaccination rates to risky sexual behavior. Here are five studies that demonstrate the benefits of bringing empirical social science into the developing world….(More)”
