Citizen science volunteers driven by desire to learn

Curated on August 9, 2017August 3, 2018 by Stefaan Verhulst

UoP News: “People who give up their time for online volunteering are mainly motivated by a desire to learn, a new study has found.

The research surveyed volunteers on ‘citizen science’ projects and suggests that this type of volunteering could be used to increase general knowledge of science within society.

The study, led by Dr Joe Cox from the Department of Economics and Finance, discovered that an appetite to learn more about the subject was the number one driver for online volunteers, followed by being part of a community. It also revealed that many volunteers are motivated by a desire for escapism.

Online volunteering and crowdsourcing projects typically involve input from large numbers of contributors working individually but towards a common goal. This study surveyed 2000 people who volunteer for ‘citizen science’ projects hosted by Zooniverse, a collection of research projects that rely on volunteers to help scientists with the challenge of interpreting massive amounts of data….“What was interesting was that characteristics such as age, gender and level of education had no correlation with the amount of time people give up and the length of time they stay on a project. These participants were relatively highly educated compared with the rest of the population, but those with the highest levels of education do not appear to contribute the most effort and information towards these projects.”

The study noticed pronounced changes in how people are motivated at different stages of the volunteer process. While a desire to learn is the most important motivation among contributors at the early stages, the opportunities for social interaction and escapism become more important motivations at later stages….

He suggests that online volunteering and citizen science projects could incentivise participation by offering clearly defined opportunities for learning, while representing an effective way of increasing scientific literacy and knowledge within society….(More)”.

Elsevier Is Becoming a Data Company. Should Universities Be Wary?

Curated on August 9, 2017August 20, 2018 by Stefaan Verhulst

Paul Basken at The Chronicle of Higher Education: “As universities have slowly pushed their scientists to embrace open-access journals, publishers will need new profit centers. Elsevier appears well ahead of the pack in creating a network of products that scientists can use to record, share, store, and measure the value to others of the surging amounts of data they produce.

“Maybe all publishers are going, or wish they were” going, in the direction of becoming data companies, said Vincent Larivière, an associate professor of information science at the University of Montreal. “But Elsevier is the only one that is there.”

A Suite of Services

Universities also recognize the future of data. Their scientists are already seeing that widely and efficiently sharing data in fields such as cancer research has enabled accomplishments that have demonstrably saved lives.

In their eagerness to embrace that future, however, universities may not be paying enough attention to what their choices of systems may eventually cost them, warned Roger C. Schonfeld, a program director at Ithaka S+R. With its comprehensive data-services network, Mr. Schonfeld wrote earlier this year, Elsevier appears ready “to lock in scientists to a research workflow no less powerful than the strength of the lock-in libraries have felt to ‘big deal’ bundles.”….

Some open-access advocates say the situation points to an urgent need to create more robust nonprofit alternatives to Elsevier’s product line of data-compiling and sharing tools. But so far financial backing for the developmental work is thin. One of the best known attempts is the Open Science Framework, a web-based data interface built by the Center for Open Science, which has an annual budget of about $6 million, provided largely by foundations and other private donors.

In general, U.S. research universities — a $70 billion scientific enterprise — have not made major contributions to such projects. The Association of American Universities and the Association of Public and Land-grant Universities have, however, formed a team that’s begun studying the future of data sharing. So far, that effort has been focused on more basic steps such as establishing data-storage facilities, linking them together, and simply persuading scientists to take seriously the need to share data.…(More)”

Chicago police see less violent crime after using predictive code

Curated on August 8, 2017August 3, 2018 by Stefaan Verhulst

Jon Fingas at Engadget: “Law enforcement has been trying predictive policing software for a while now, but how well does it work when it’s put to a tough test? Potentially very well, according to Chicago police. The city’s 7th District police reportthat their use of predictive algorithms helped reduce the number of shootings 39 percent year-over-year in the first 7 months of 2017, with murders dropping by 33 percent. Three other districts didn’t witness as dramatic a change, but they still saw 15 to 29 percent reductions in shootings and a corresponding 9 to 18 percent drop in murders.

It mainly comes down to knowing where and when to deploy officers. One of the tools used in the 7th District, HunchLab, blends crime statistics with socioeconomic data, weather info and business locations to determine where crimes are likely to happen. Other tools (such as the Strategic Subject’s List and ShotSpotter) look at gang affiliation, drug arrest history and gunfire detection sensors.

If the performance holds, It’ll suggest that predictive policing can save lives when crime rates are particularly high, as they have been on Chicago’s South Side. However, both the Chicago Police Department and academics are quick to stress that algorithms are just one part of a larger solution. Officers still have be present, and this doesn’t tackle the underlying issues that cause crime, such as limited access to education and a lack of economic opportunity. Still, any successful reduction in violence is bound to be appreciated….(More)”.

Digital Decisions Tool

Curated on August 8, 2017August 3, 2018 by Stefaan Verhulst

Center for Democracy and Technology (CDT): “Two years ago, CDT embarked on a project to explore what we call “digital decisions” – the use of algorithms, machine learning, big data, and automation to make decisions that impact individuals and shape society. Industry and government are applying algorithms and automation to problems big and small, from reminding us to leave for the airport to determining eligibility for social services and even detecting deadly diseases. This new era of digital decision-making has created a new challenge: ensuring that decisions made by computers reflect values like equality, democracy, and justice. We want to ensure that big data and automation are used in ways that create better outcomes for everyone, and not in ways that disadvantage minority groups.

The engineers and product managers who design these systems are the first line of defense against unfair, discriminatory, and harmful outcomes. To help mitigate harm at the design level, we have launched the first public version of our digital decisions tool. We created the tool to help developers understand and mitigate unintended bias and ethical pitfalls as they design automated decision-making systems.

About the digital decisions tool

This interactive tool translates principles for fair and ethical automated decision-making into a series of questions that can be addressed during the process of designing and deploying an algorithm. The questions address developers’ choices, such as what data to use to train an algorithm, what factors or features in the data to consider, and how to test the algorithm. They also ask about the systems and checks in place to assess risk and ensure fairness. These questions should provoke thoughtful consideration of the subjective choices that go into building an automated decision-making system and how those choices could result in disparate outcomes and unintended harms.

The tool is informed by extensive research by CDT and others about how algorithms and machine learning work, how they’re used, the potential risks of using them to make important decisions, and the principles that civil society has developed to ensure that digital decisions are fair, ethical, and respect civil rights. Some of this research is summarized on CDT’s Digital Decisions webpage….(More)”.

Building Digital Government Strategies

Curated on August 8, 2017August 3, 2018 by Stefaan Verhulst

Book by Rodrigo Sandoval-Almazan et al: “This book provides key strategic principles and best practices to guide the design and implementation of digital government strategies. It provides a series of recommendations and findings to think about IT applications in government as a platform for information, services and collaboration, and strategies to avoid identified pitfalls. Digital government research suggests that information technologies have the potential to generate immense public value and transform the relationships between governments, citizens, businesses and other stakeholders. However, developing innovative and high impact solutions for citizens hinges on the development of strategic institutional, organizational and technical capabilities.

Thus far, particular characteristics and problems of the public sector organization promote the development of poorly integrated and difficult to maintain applications. For example, governments maintain separate applications for open data, transparency, and public services, leading to duplication of efforts and a waste of resources. The costs associated with maintaining such sets of poorly integrated systems may limit the use of resources to future projects and innovation.

This book provides best practices and recommendations based on extensive research in both Mexico and the United States on how governments can develop a digital government strategy for creating public value, how to finance digital innovation in the public sector, how to building successful collaboration networks and foster citizen engagement, and how to correctly implement open government projects and open data. It will be of interest to researchers, practitioners, students, and public sector IT professionals that work in the design and implementation of technology-based projects and programs….(More)”.

Rise of the Government Chatbot

Curated on August 7, 2017August 3, 2018 by Stefaan Verhulst

Zack Quaintance at Government Technology: “A robot uprising has begun, except instead of overthrowing mankind so as to usher in a bleak yet efficient age of cold judgment and colder steel, this uprising is one of friendly robots (so far).

Which is all an alarming way to say that many state, county and municipal governments across the country have begun to deploy relatively simple chatbots, aimed at helping users get more out of online public services such as a city’s website, pothole reporting and open data. These chatbots have been installed in recent months in a diverse range of places including Kansas City, Mo.; North Charleston, S.C.; and Los Angeles — and by many indications, there is an accompanying wave of civic tech companies that are offering this tech to the public sector.

They range from simple to complex in scope, and most of the jurisdictions currently using them say they are doing so on somewhat of a trial or experimental basis. That’s certainly the case in Kansas City, where the city now has a Facebook chatbot to help users get more out of its open data portal.

“The idea was never to create a final chatbot that was super intelligent and amazing,” said Eric Roche, Kansas City’s chief data officer. “The idea was let’s put together a good effort, and put it out there and see if people find it interesting. If they use it, get some lessons learned and then figure out — either in our city, or with developers, or with people like me in other cities, other chief data officers and such — and talk about the future of this platform.”

Roche developed Kansas City’s chatbot earlier this year by working after hours with Code for Kansas City, the local Code for America brigade — and he did so because since in the four-plus years the city’s open data program has been active, there have been regular concerns that the info available through it was hard to navigate, search and use for average citizens who aren’t data scientists and don’t work for the city (a common issue currently being addressed by many jurisdictions). The idea behind the Facebook chatbot is that Roche can program it with a host of answers to the most prevalent questions, enabling it to both help interested users and save him time for other work….

In North Charleston, S.C., the city has adopted a text-based chatbot, which goes above common 311-style interfaces by allowing users to report potholes or any other lapses in city services they may notice. It also allows them to ask questions, which it subsequently answers by crawling city websites and replying with relevant links, said Ryan Johnson, the city’s public relations coordinator.

North Charleston has done this by partnering with a local tech startup that has deep roots in the area’s local government. The company is called Citibot …

With Citibot, residents can report a pothole at 2 a.m., or they can get info about street signs or trash pickup sent right to their phones.

There are also more complex chatbot technologies taking hold at both the civic and state levels, in Los Angeles and Mississippi, to be exact.

Mississippi’s chatbot is called Missi, and its capabilities are vast and nuanced. Residents can even use it for help submitting online payments. It’s accessible by clicking a small chat icon on the side of the website.

Back in May, Los Angeles rolled out Chip, or City Hall Internet Personality, on the Los Angeles Business Assistance Virtual Network. The chatbot aims to assist visitors by operating as a 24/7 digital assistant for visitors to the site, helping them navigate it and better understand its services by answering their inquiries. It is capable of presenting info from anywhere on the site, and it can even go so far as helping users fill out forms or set up email alerts….(More)”

The Nudging Divide in the Digital Big Data Era

Curated on August 7, 2017August 3, 2018 by Stefaan Verhulst

Julia M. Puaschunder in the International Robotics & Automation Journal: “Since the end of the 1970ies a wide range of psychological, economic and sociological laboratory and field experiments proved human beings deviating from rational choices and standard neo-classical profit maximization axioms to fail to explain how human actually behave. Behavioral economists proposed to nudge and wink citizens to make better choices for them with many different applications. While the motivation behind nudging appears as a noble endeavor to foster peoples’ lives around the world in very many different applications, the nudging approach raises questions of social hierarchy and class division. The motivating force of the nudgital society may open a gate of exploitation of the populace and – based on privacy infringements – stripping them involuntarily from their own decision power in the shadow of legally-permitted libertarian paternalism and under the cloak of the noble goal of welfare-improving global governance. Nudging enables nudgers to plunder the simple uneducated citizen, who is neither aware of the nudging strategies nor able to oversee the tactics used by the nudgers.

The nudgers are thereby legally protected by democratically assigned positions they hold or by outsourcing strategies used, in which social media plays a crucial rule. Social media forces are captured as unfolding a class dividing nudgital society, in which the provider of social communication tools can reap surplus value from the information shared of social media users. The social media provider thereby becomes a capitalist-industrialist, who benefits from the information shared by social media users, or so-called consumer-workers, who share private information in their wish to interact with friends and communicate to public. The social media capitalist-industrialist reaps surplus value from the social media consumer-workers’ information sharing, which stems from nudging social media users. For one, social media space can be sold to marketers who can constantly penetrate the consumer-worker in a subliminal way with advertisements. But also nudging occurs as the big data compiled about the social media consumer-worker can be resold to marketers and technocrats to draw inferences about consumer choices, contemporary market trends or individual personality cues used for governance control, such as, for instance, border protection and tax compliance purposes.

The law of motion of the nudging societies holds an unequal concentration of power of those who have access to compiled data and who abuse their position under the cloak of hidden persuasion and in the shadow of paternalism. In the nudgital society, information, education and differing social classes determine who the nudgers and who the nudged are. Humans end in different silos or bubbles that differ in who has power and control and who is deceived and being ruled. The owners of the means of governance are able to reap a surplus value in a hidden persuasion, protected by the legal vacuum to curb libertarian paternalism, in the moral shadow of the unnoticeable guidance and under the cloak of the presumption that some know what is more rational than others. All these features lead to an unprecedented contemporary class struggle between the nudgers (those who nudge) and the nudged (those who are nudged), who are divided by the implicit means of governance in the digital scenery. In this light, governing our common welfare through deceptive means and outsourced governance on social media appears critical. In combination with the underlying assumption of the nudgers knowing better what is right, just and fair within society, the digital age and social media tools hold potential unprecedented ethical challenges….(More)”

Algorithmic Transparency for the Smart City

Curated on August 7, 2017August 3, 2018 by Stefaan Verhulst

Paper by Robert Brauneis and Ellen P. Goodman: “Emerging across many disciplines are questions about algorithmic ethics – about the values embedded in artificial intelligence and big data analytics that increasingly replace human decisionmaking. Many are concerned that an algorithmic society is too opaque to be accountable for its behavior. An individual can be denied parole or denied credit, fired or not hired for reasons she will never know and cannot be articulated. In the public sector, the opacity of algorithmic decisionmaking is particularly problematic both because governmental decisions may be especially weighty, and because democratically-elected governments bear special duties of accountability. Investigative journalists have recently exposed the dangerous impenetrability of algorithmic processes used in the criminal justice field – dangerous because the predictions they make can be both erroneous and unfair, with none the wiser.

We set out to test the limits of transparency around governmental deployment of big data analytics, focusing our investigation on local and state government use of predictive algorithms. It is here, in local government, that algorithmically-determined decisions can be most directly impactful. And it is here that stretched agencies are most likely to hand over the analytics to private vendors, which may make design and policy choices out of the sight of the client agencies, the public, or both. To see just how impenetrable the resulting “black box” algorithms are, we filed 42 open records requests in 23 states seeking essential information about six predictive algorithm programs. We selected the most widely-used and well-reviewed programs, including those developed by for-profit companies, nonprofits, and academic/private sector partnerships. The goal was to see if, using the open records process, we could discover what policy judgments these algorithms embody, and could evaluate their utility and fairness.

To do this work, we identified what meaningful “algorithmic transparency” entails. We found that in almost every case, it wasn’t provided. Over-broad assertions of trade secrecy were a problem. But contrary to conventional wisdom, they were not the biggest obstacle. It will not usually be necessary to release the code used to execute predictive models in order to dramatically increase transparency. We conclude that publicly-deployed algorithms will be sufficiently transparent only if (1) governments generate appropriate records about their objectives for algorithmic processes and subsequent implementation and validation; (2) government contractors reveal to the public agency sufficient information about how they developed the algorithm; and (3) public agencies and courts treat trade secrecy claims as the limited exception to public disclosure that the law requires. Although it would require a multi-stakeholder process to develop best practices for record generation and disclosure, we present what we believe are eight principal types of information that such records should ideally contain….(More)”.

Scientists Use Google Earth and Crowdsourcing to Map Uncharted Forests

Curated on August 7, 2017August 3, 2018 by Stefaan Verhulst

Katie Fletcher, Tesfay Woldemariam and Fred Stolle at EcoWatch: “No single person could ever hope to count the world’s trees. But a crowd of them just counted the world’s drylands forests—and, in the process, charted forests never before mapped, cumulatively adding up to an area equivalent in size to the Amazon rainforest.

Current technology enables computers to automatically detect forest area through satellite data in order to adequately map most of the world’s forests. But drylands, where trees are fewer and farther apart, stymied these modern methods. To measure the extent of forests in drylands, which make up more than 40 percent of land surface on Earth, researchers from UN Food and Agriculture Organization, World Resources Institute and several universities and organizations had to come up with unconventional techniques. Foremost among these was turning to residents, who contributed their expertise through local map-a-thons….

Google Earth collects satellite data from several satellites with a variety of resolutions and technical capacities. The dryland satellite imagery collection compiled by Google from various providers, including Digital Globe, is of particularly high quality, as desert areas have little cloud cover to obstruct the views. So while difficult for algorithms to detect non-dominant land cover, the human eye has no problem distinguishing trees in the landscapes. Using this advantage, the scientists decided to visually count trees in hundreds of thousands of high-resolution images to determine overall dryland tree cover….

Armed with the quality images from Google that allowed researchers to see objects as small as half a meter (about 20 inches) across, the team divided the global dryland images into 12 regions, each with a regional partner to lead the counting assessment. The regional partners in turn recruited local residents with practical knowledge of the landscape to identify content in the sample imagery. These volunteers would come together in participatory mapping workshops, known colloquially as “map-a-thons.”…

Utilizing local landscape knowledge not only improved the map quality but also created a sense of ownership within each region. The map-a-thon participants have access to the open source tools and can now use these data and results to better engage around land use changes in their communities. Local experts, including forestry offices, can also use this easily accessible application to continue monitoring in the future.

Global Forest Watch uses medium resolution satellites (30 meters or about 89 feet) and sophisticated algorithms to detect near-real time deforestation in densely forested area. The dryland tree cover maps complement Global Forest Watch by providing the capability to monitor non-dominant tree cover and small-scale, slower-moving events like degradation and restoration. Mapping forest change at this level of detail is critical both for guiding land decisions and enabling government and business actors to demonstrate their pledges are being fulfilled, even over short periods of time.

The data documented by local participants will enable scientists to do many more analyses on both natural and man-made land changes including settlements, erosion features and roads. Mapping the tree cover in drylands is just the beginning….(More)”.
