Identifying commonly used and potentially unsafe transit transfers with crowdsourcing

Curated on Posted on by Stefaan Verhulst

Paper by Elizabeth J.Traut and Aaron Steinfeld: “Public transit is an important contributor to sustainable transportation as well as a public service that makes necessary travel possible for many. Poor transit transfers can lead to both a real and perceived reduction in convenience and safety, especially for people with disabilities. Poor transfers can expose riders to inclement weather and crime, and they can reduce transit ridership by motivating riders who have the option of driving or using paratransit to elect a more expensive and inefficient travel mode. Unfortunately, knowledge about inconvenient, missed, and unsafe transit transfers is sparse and incomplete.

We show that crowdsourced public transit ridership data, which is more scalable than conducting traditional surveys, can be used to analyze transit transfers. The Tiramisu Transit app merges open transit data with information contributed by users about which trips they take. We use Tiramisu data to do origin-destination analysis and identify connecting trips to create a better understanding of where and when poor transfers are occurring in the Pittsburgh region. We merge the results with data from other open public data sources, including crime data, to create a data resource that can be used for planning and identification of locations where bus shelters and other infrastructure improvements may facilitate safer and more comfortable waits and more accessible transfers. We use generalizable methods to ensure broader value to both science and practitioners.

We present a case study of the Pittsburgh region, in which we identified and characterized 338 transfers from 142 users. We found that 66.6% of transfers were within 0.4 km (0.25 mi.) and 44.1% of transfers were less than 10 min. We identified the geographical distribution of transfers and found several highly-utilized transfer locations that were not identified by the Port Authority of Allegheny County as recommended transfer points, and so might need more planning attention. We cross-referenced transfer location and wait time data with crime levels to provide additional planning insight….(More)”.

A Review of Citizen Science and Crowdsourcing in Applications of Pluvial Flooding

Curated on Posted on by Stefaan Verhulst

Jonathan D. Paul in Frontiers in Earth Science: “Pluvial flooding can have devastating effects, both in terms of loss of life and damage. Predicting pluvial floods is difficult and many cities do not have a hydrodynamic model or an early warning system in place. Citizen science and crowdsourcing have the potential for contributing to early warning systems and can also provide data for validating flood forecasting models. Although there are increasing applications of citizen science and crowdsourcing in fluvial hydrology, less is known about activities related to pluvial flooding. Hence the aim of this paper is to review current activities in citizen science and crowdsourcing with respect to applications of pluvial flooding.

Based on a search in Scopus, the papers were first filtered for relevant content and then classified into four main themes. The first two themes were divided into (i) applications relevant during a flood event, which includes automated street flooding detection using crowdsourced photographs and sensors, analysis of social media, and online and mobile applications for flood reporting; and (ii) applications related to post-flood events. The use of citizen science and crowdsourcing for model development and validation is the third theme while the development of integrated systems is theme four. All four main areas of research have the potential to contribute to early warning systems and build community resilience. Moreover, developments in one will benefit others, e.g., further developments in flood reporting applications and automated flood detection systems will yield data useful for model validation….(More)”.

Congress needs your input (but don’t call it crowdsourcing)

Curated on Posted on by Stefaan Verhulst

Lorelei Kelly at TechCrunch: “As it stands, Congress does not have the technical infrastructure to ingest all this new input in any systematic way. Individual members lack a method to sort and filter signal from noise or trusted credible knowledge from malicious falsehood and hype.

What Congress needs is curation, not just more information

Curation means discovering, gathering and presenting content. This word is commonly thought of as the job of librarians and museums, places we go to find authentic and authoritative knowledge. Similarly, Congress needs methods to sort and filter information as required within the workflow of lawmaking. From personal offices to committees, members and their staff need context and informed judgement based on broadly defined expertise. The input can come from individuals or institutions. It can come from the wisdom of colleagues in Congress or across the federal government. Most importantly, it needs to be rooted in local constituents and it needs to be trusted.

It is not to say that crowdsourcing is unimportant for our governing system. But input methods that include digital must demonstrate informed and accountable deliberative methods over time. Governing is the curation part of democracy. Governing requires public review, understanding of context, explanation and measurements of value for the nation as a whole. We are already thinking about how to create an ethical blockchain. Why not the same attention for our most important democratic institution?

Governing requires trade-offs that elicit emotion and sometimes anger. But as in life, emotions require self-regulation. In Congress, this means compromise and negotiation. In fact, one of the reasons Congress is so stuck is that its own deliberative process has declined at every level. Besides the official committee process stalling out, members have few opportunities to be together as colleagues, and public space is increasingly antagonistic and dangerous.

With so few options, members are left with blunt communications objects like clunky mail management systems and partisan talking points. This means that lawmakers don’t use public input for policy formation as much as to surveil public opinion.

Any path forward to the 21st century must include new methods to (1) curate and hear from the public in a way that informs policy AND (2) incorporate real data into a results-driven process.

While our democracy is facing unprecedented stress, there are bright spots. Congress is again dedicating resources to an in-house technologyassessment capacity. Earlier this month, the new 116th Congress created a Select Committee on the Modernization of Congress. It will be chaired by Rep. Derek Kilmer (D-WA). Then the Open Government Data Actbecame law. This law will potentially scale the level of access to government data to unprecedented levels. It will require that all public-facing federal data must be machine-readable and reusable. This is a move in the right direction, and now comes the hard part.

Marci Harris, the CEO of civic startup Popvox, put it well, “The Foundations for Evidence-Based Policymaking (FEBP) Act, which includes the OPEN Government Data Act, lays groundwork for a more effective, accountable government. To realize the potential of these new resources, Congress will need to hire tech literate staff and incorporate real data and evidence into its oversight and legislative functions.”

In forsaking its own capacity for complex problem solving, Congress has become non-competitive in the creative process that moves society forward. During this same time period, all eyes turned toward Silicon Valley to fill the vacuum. With mass connection platforms and unlimited personal freedom, it seemed direct democracy had arrived. But that’s proved a bust. If we go by current trends, entrusting democracy to Silicon Valley will give us perfect laundry and fewer voting rights. Fixing democracy is a whole-of-nation challenge that Congress must lead.

Finally, we “the crowd” want a more effective governing body that incorporates our experience and perspective into the lawmaking process, not just feel-good form letters thanking us for our input. We also want a political discourse grounded in facts. A “modern” Congress will provide both, and now we have the institutional foundation in place to make it happen….(More)”.

MIT Sloan study finds crowdsourcing an effective tool to fight spread of fake news

Curated on Posted on by Stefaan Verhulst

MIT Sloan Press Release: “Fake news isn’t a new problem, but it’s becoming a greater concern because of social media, where it is easily created and rapidly distributed. A recent study by MIT Sloan School of Management Prof. David Rand and Prof. Gordon Pennycook of the University of Regina finds there is a possible solution: crowdsourcing. As their research shows that laypeople trust reputable news outlets more than outlets that create misinformation, social media platforms could use trust ratings to inform how they promote content.

“There has been a lot of research examining fake news and how it spreads, but this study is among the first to suggest a potential long-term solution, which is cause for measured optimism. If we can decrease the amount of misinformation spreading on social media, we can increase agreement on basic facts across political parties, which will hopefully lead to less political polarization and a greater ability to compromise on how to run the country,” says Rand. “It may also make it harder for individuals to win elections based on false claims.”

He notes that current solutions for fighting misinformation deployed by social media companies haven’t been that effective. For example, partnering with fact-checkers isn’t scalable because they can’t keep up with the rapid creation of false stories. Further, putting warnings on content found to be false can be counterproductive, because it makes misleading stories that didn’t get checked seem more accurate – the “implied truth” effect.

“Our study is good news because we find a scalable solution to this problem, based on the surprisingly good judgment of everyday Americans. Things may not be as hopeless as most coverage of fake news makes you think,” says Rand.

In their study, Rand and Pennycook examined whether crowdsourcing could work as an effective tool in fighting the spread of misinformation. They asked laypeople to rate familiarity with and trust in news sources across three categories: mainstream media outlets, hyper-partisan websites, and websites that produce blatantly false content (“fake news”). The pool of people surveyed was nationally representative across age, gender, ethnicity, and political affiliations. They also asked professional fact-checkers the same questions to compare responses.

They found that laypeople trust reputable news outlets more than those that create misinformation and that the trust ratings of the laypeople surveyed closely matched the trust ratings of professional fact-checkers. “Our results show that laypeople are much better than many would have expected at knowing which outlets to trust,” says Rand. “Although there were clear partisan differences, with Republicans distrusting all mainstream outlets (except for Fox News) relative to Democrats, there was a remarkable consensus regarding non-mainstream outlets being untrustworthy.”…(More)”.

What Sustains Individuals’ Participation in Crowdsourcing Contests?

Curated on Posted on by Stefaan Verhulst

Paper by Xuan Wang et al: Crowdsourcing contests have become widely adopted for idea generation and problem-solving in various companies in different industries. The success of crowdsourcing depends on the sustained participation and quality-submissions of the individuals. Yet, little is known about the factors that influence individuals’ continued participation in these contests. We address this issue, by conducting an empirical study using data from an online crowdsourcing contest platform, Kaggle, which delivers data science and machine learning solutions and models to its clients.

The findings show that the community activities and team activities do not contribute to motivating the continued participation, but tenure does significantly affect the continued participation. We also found statistically significant effects of amount of prize, number of competitions, previous team performance, and competition duration on individuals sustained participation in crowdsourcing contests. This research contributes to the literature by identifying the factors influencing individuals’ sustained participation in crowdsourcing contests…(More)”.

Outcomes of open government: Does an online platform improve citizens’ perception of local government?

Curated on Posted on by Stefaan Verhulst

Paper by Lisa Schmidthuber et al: “Governments all over the world have implemented citizensourcing initiatives to integrate citizens into decision-making processes. A more participative decision-making process is associated with an open government and assumed to benefit public service quality and interactive value creation. The purpose of this paper is to highlight the outcomes of open government initiatives and ask to what extent open government participation is related to perceived outcomes of open government....

Data conducted from a survey among users of a citizensourcing platform and platform data are used to perform non-parametric analyses and examine the relationship between platform participation and perceived outcomes of open government....

The findings of this paper suggest that active platform usage positively relates to several outcomes perceived by citizens, such as improved information flow, increased trust in and satisfaction with local government. In contrast, repetitive participation does not significantly relate to users’ outcome evaluation….(More)”.

Crowdsourced mapping in crisis zones: collaboration, organisation and impact

Curated on Posted on by Stefaan Verhulst

Amelia Hunt and Doug Specht in the Journal of International Humanitarian Action:  “Crowdsourced mapping has become an integral part of humanitarian response, with high profile deployments of platforms following the Haiti and Nepal earthquakes, and the multiple projects initiated during the Ebola outbreak in North West Africa in 2014, being prominent examples. There have also been hundreds of deployments of crowdsourced mapping projects across the globe that did not have a high profile.

This paper, through an analysis of 51 mapping deployments between 2010 and 2016, complimented with expert interviews, seeks to explore the organisational structures that create the conditions for effective mapping actions, and the relationship between the commissioning body, often a non-governmental organisation (NGO) and the volunteers who regularly make up the team charged with producing the map.

The research suggests that there are three distinct areas that need to be improved in order to provide appropriate assistance through mapping in humanitarian crisis: regionalise, prepare and research. The paper concludes, based on the case studies, how each of these areas can be handled more effectively, concluding that failure to implement one area sufficiently can lead to overall project failure….(More)”

IBM aims to use crowdsourced sensor data to improve local weather forecasting globally

Curated on Posted on by Stefaan Verhulst

Larry Dignan at ZDN: “IBM is hoping that mobile barometric sensors from individuals opting in, supercomputing ,and the Internet of Things can make weather forecasting more local globally.

Big Blue, which owns The Weather Company, will outline the IBM Global High-Resolution Atmospheric Forecasting System (GRAF). GRAF incorporates IoT data in its weather models via crowdsourcing.

While hyper local weather forecasts are available in the US, Japan, and some parts of Western Europe, many regions in the world lack an accurate picture of weather.

Mary Glackin, senior vice president of The Weather Company, said the company is “trying to fill in the blanks.” She added, “In a place like India, weather stations are kilometers away. We think this can be as significant as bringing satellite data into models.”

For instance, the developing world gets forecasts based on global data that are updated every 6 hours and resolutions at 10km to 15km. By using GRAF, IBM said it can offer forecasts for the day ahead that are updated hourly on average and have a 3km resolution….(More)”.

Are We Game for Gamification? Potential and Limits of Game-Design Elements to Foster Civic Engagement and Encourage Participation

Curated on Posted on by Stefaan Verhulst

Paper by Gianluca Sgueo: “Together with robotics, artificial intelligence, biometrics and data, (serious-) games fall within the technological paradigm that is evolving the administration of public entities. The use of game-design elements beyond mere entertainment is not entirely a new approach to problem solving. Business actors have long-incorporated game-design elements – such as badges, points, levels, rankings, prize challenges, and virtual currencies – into their marketing and communications strategies. However this phenomenon has progressed dramatically in recent years, with the public sector at the forefront of experiments with ‘gamification’. To public regulators, the gamification of governance seems promising on three fronts. First, it encourages innovative, and cost-saving, approaches to regulatory challenges. Second, it presents an opportunity to nurture the trust of citizens, and thus enhance perceptions of legitimacy. Third, it creates new incentives to promote civic engagement and foster participation. What was once simplistically labelled as ‘play’ could become a primary form of interaction with public regulators. After all, who wouldn’t want to have an opportunity to impact on public choices, and do so in a non-boring, novel and dynamic, way?

The gamification of governance – claims this paper – shows great potential to foster civic engagement and encourage participation in policy-making. The data around the general publics’ response and perception to game-design incentives are encouraging. Yet – argues this paper – gamification is not without risks. Various challenges are posed by gamified policy-making, particularly with regards to security and inclusiveness (i.e. do gamified policies conform to recognized security and privacy standards? Are they sufficiently inclusive?). Additionally, concerns surround the quality of public’s response to gamified incentives (i.e. is gamification merely encouraging low-risk/low-cost engagement, or does it genuinely drive public participation, both online and offline?). Questions have also been raised about the longevity and duration of engagement – are game-design elements fostering long-term, durable, civic engagement, or do they merely encourage one-time, occasional, participation? This paper develops around five concepts that are key to understanding the link between gamification with civic engagement and public sector’s innovation. The first is “Reputation”, followed by “Automation” and “Structure”. The fourth and fifth consist of “Nudging” and “Crowdsourcing”, respectively. Alongside the analysis of these concepts, and their respective interplay, the paper provides an empirical account of efforts to ‘gamify’ public policies, at both national and supranational levels; it illustrates the outcomes that public regulators expect from efforts with gamification; and it considers the weaknesses, both practical and theoretical, related to the use of game-design elements to encourage participation….(More)”.

Long Live the Human Network Effect

Curated on Posted on by Stefaan Verhulst

Julia Hobsbawm at Strategy + Business: “Picture the scene. The eyes of the world are on the Tham Luang cave system in Thailand, near the border with Myanmar. Trapped on a rock ledge deep inside is the Wild Boars soccer team of 12 boys and their coach, who had ventured into the caves about two weeks earlier. It is monsoon season. Water is rising and oxygen levels are falling. Not all of the boys can even swim. Time is running out.

Elon Musk proposes building a “kid-sized submarine” to assist the rescue effort. Musk’s solution is politely declined by Thai authorities as “not practical.” In fact, by the time Musk’s sub arrives, most of the boys are already out, alive. One of the most audacious, moving, complex, and successful rescue operations in history relied not on a single technology or hero but on the collaboration of many people, working together in a spontaneous network.

This web of connections came together organically and quickly, unassisted by algorithms, in a unique collaboration led by humans. It was a stunning example of what physicist Albert-László Barabási calls “scale-free networks”: networks that reproduce exponentially by their very nature. The exact same network effects that can be lethal in spreading a virus can be productive — beautiful, even — in creating a web of diverse human skills quickly. Networks, as Barabási puts it, “are everywhere. You just have to look for them.”…

Networks that come together like this and use technology, community, and communications in a timely manner are an example of what the U.N. calls its “leave no one behind” strategy for achieving sustainable development goals. I consider it an example of social health in action: They are the kinds of collaborations that help us live full and productive lives. And in business, there is an exciting opportunity to harness social health and the power of networks to help solve problems.

This kind of social health network, perhaps unsurprisingly, is very visible in innovations in the healthcare sector. A digital health community called The Mighty, for example, is a forum to find information about rare illnesses and connect people facing similar challenges, so that they might learn from the experiences of others. It now has 90 million engagements on its website per month and a new member joins every 20 seconds….(More)”.
