Drawing on the study of different cities in the Global South, this book explores how the intensive use of data changes politics, power relations, and everyday life in contemporary cities. Across the volume, expert contributors show how urban actors, from the state to activists, are increasingly using data as a resource to empower their actions and support their claims, while also demonstrating how times of crisis are moments when the power of data is made visible. Focusing on the different dimensions of data power and politics in the urban realm, this is an important contribution to our understanding of how datafication transforms the places in which we live and how we experience them.

A new way of thinking about data science and data ethics that is informed by the ideas of intersectional feminism. Today, data science is a form of power. It has been used to expose injustice, improve health outcomes, and topple governments. But it has also been used to discriminate, police, and surveil. This potential for good, on the one hand, and harm, on the other, makes it essential to ask: Data science by whom? Data science for whom? Data science with whose interests in mind? The narratives around big data and data science are overwhelmingly white, male, and techno-heroic. In Data Feminism, Catherine D'Ignazio and Lauren Klein present a new way of thinking about data science and data ethics—one that is informed by intersectional feminist thought. Illustrating data feminism in action, D'Ignazio and Klein show how challenges to the male/female binary can help challenge other hierarchical (and empirically wrong) classification systems. They explain how, for example, an understanding of emotion can expand our ideas about effective data visualization, and how the concept of invisible labor can expose the significant human efforts required by our automated systems. And they show why the data never, ever “speak for themselves.” Data Feminism offers strategies for data scientists seeking to learn how feminism can help them work toward justice, and for feminists who want to focus their efforts on the growing field of data science. But Data Feminism is about much more than gender. It is about power, about who has it and who doesn't, and about how those differentials of power can be challenged and changed.

Argues that South Africans, like everyone else, need democracy for a more equal society What are democracies meant to do? And how does one know when one is a democratic state? These incisive questions and more by leading political scientist, Steven Friedman, underlie this robust enquiry into what democracy means for South Africa post 1994. Democracy is often viewed through a lens reflecting Western understanding. New democracies are compared to idealized notions by which the system is said to operate in the global North. The democracies of Western Europe and North America are understood to be the finished product and all others are assessed by how far they have progressed towards approximating this model. Power in Action persuasively argues against this stereotype. Friedman asserts that democracies can only work when every adult has an equal say in the public decisions that affect them.Democracy is achieved not by adopting idealized models derived from other societies–rather, it is the product of collective action by citizens who claim the right to be heard not only through public protest action, but also through the conscious exercise of influence on public and private power holders. Viewing democracy in this way challenges us to develop a deeper understanding of democracy’s challenges and in so doing to ensure that more citizens can claim a say over more decisions in society.

The data mining community has derived a broad foundation of statistical algorithms and software solutions that has allowed predictive analytics to become a standard approach used in science and industry. For many years, much emphasis has been placed on the development of predictive models. As a consequence, the market place offers a range of powerful tools, many open-source, for effective model building. However, once we turn to the operational deployment and practical application of predictive solutions within an existing IT infrastructure, we face a much more limited choice of options. Often it takes months for models to be integrated and deployed via custom code or proprietary processes. The Predictive Model Markup Language (PMML) standard has reached a significant stage of maturity and has obtained broad industry support, allowing users to develop predictive solutions within one application and use another to execute them. Previously, this was very difficult, but with PMML, the exchange of predictive solutions between compliant applications is now straightforward. The aim of this book is to present PMML from a practical perspective. It contains a variety of code snippets so that concepts are made clear through the use of examples. Readers are assumed to have a basic knowledge of predictive analytics and its techniques and so the book is intended for data mining movers and shakers: anyone interested in moving predictive analytic solutions between applications, including students and scientists. PMML in Action is a great way to learn how to represent your predictive solutions through a mature and refined open standard. For the 2nd edition, the book has been completely revised for PMML 4.1, the latest version of PMML. It includes new chapters and an expanded description of how to represent multiple models in PMML, including model ensemble, segmentation, chaining, and composition. The book is divided into six parts, taking you in a PMML journey in which language elements and attributes are used to represent not only modeling techniques but also data pre- and post-processing. With PMML, users benefit from a single and concise standard to represent predictive models, thus avoiding the need for custom code and proprietary solutions. You too can join the PMML movement!

A brilliant condemnation of political hobbyism—treating politics like entertainment—and a call to arms for well-meaning, well-informed citizens who consume political news, but do not take political action. Who is to blame for our broken politics? The uncomfortable answer to this question starts with ordinary citizens with good intentions. We vote (sometimes) and occasionally sign a petition or attend a rally. But we mainly “engage” by consuming politics as if it’s a sport or a hobby. We soak in daily political gossip and eat up statistics about who’s up and who’s down. We tweet and post and share. We crave outrage. The hours we spend on politics are used mainly as pastime. Instead, we should be spending the same number of hours building political organizations, implementing a long-term vision for our city or town, and getting to know our neighbors, whose votes will be needed for solving hard problems. We could be accumulating power so that when there are opportunities to make a difference—to lobby, to advocate, to mobilize—we will be ready. But most of us who are spending time on politics today are focused inward, choosing roles and activities designed for our short-term pleasure. We are repelled by the slow-and-steady activities that characterize service to the common good. In Politics Is for Power, pioneering and brilliant data analyst Eitan Hersh shows us a way toward more effective political participation. Aided by political theory, history, cutting-edge social science, as well as remarkable stories of ordinary citizens who got off their couches and took political power seriously, this book shows us how to channel our energy away from political hobbyism and toward empowering our values.
