Our path to better science in less time using open data science tools

Curated on Posted on by Stefaan Verhulst

Julia S. Stewart Lowndes et al in Nature: “Reproducibility has long been a tenet of science but has been challenging to achieve—we learned this the hard way when our old approaches proved inadequate to efficiently reproduce our own work. Here we describe how several free software tools have fundamentally upgraded our approach to collaborative research, making our entire workflow more transparent and streamlined. By describing specific tools and how we incrementally began using them for the Ocean Health Index project, we hope to encourage others in the scientific community to do the same—so we can all produce better science in less time.

Figure 1: Better science in less time, illustrated by the Ocean Health Index project.
Figure 1

Every year since 2012 we have repeated Ocean Health Index (OHI) methods to track change in global ocean health36,37. Increased reproducibility and collaboration has reduced the amount of time required to repeat methods (size of bubbles) with updated data annually, allowing us to focus on improving methods each year (text labels show the biggest innovations). The original assessment in 2012 focused solely on scientific methods (for example, obtaining and analysing data, developing models, calculating, and presenting results; dark shading). In 2013, by necessity we gave more focus to data science (for example, data organization and wrangling, coding, versioning, and documentation; light shading), using open data science tools. We established R as the main language for all data preparation and modelling (using RStudio), which drastically decreased the time involved to complete the assessment. In 2014, we adopted Git and GitHub for version control, project management, and collaboration. This further decreased the time required to repeat the assessment. We also created the OHI Toolbox, which includes our R package ohicore for core analytical operations used in all OHI assessments. In subsequent years we have continued (and plan to continue) this trajectory towards better science in less time by improving code with principles of tidy data33; standardizing file and data structure; and focusing more on communication, in part by creating websites with the same open data science tools and workflow.

ControCurator: Understanding Controversy Using Collective Intelligence

Curated on Posted on by Stefaan Verhulst

Paper by Benjamin Timmermans et al: “There are many issues in the world that people do not agree on, such as Global Warming [Cook et al. 2013], Anti-Vaccination [Kata 2010] and Gun Control [Spitzer 2015]. Having opposing opinions on such topics can lead to heated discussions, making them appear controversial. Such opinions are often expressed through news articles and social media. There are increasing calls for methods to detect and monitor these online discussions on different topics. Existing methods focus on using sentiment analysis and Wikipedia for identifying controversy [Dori-Hacohen and Allan 2015]. The problem with this is that it relies on a well structured and existing debate, which may not always be the case. Take for instance news reporting during large disasters, in which case the structure of a discussion is not yet clear and may change rapidly. Adding to this is that there is currently no agreed upon definition as to what exactly defines controversy. It is only agreed that controversy arises when there is a large debate by people with opposing viewpoints, but we do not yet understand which are the characteristic aspects and how they can be measured. In this paper we use the collective intelligence of the crowd in order to gain a better understanding of controversy by evaluating the aspects that have impact on it….(More)”

Digital platforms and democracy

Curated on Posted on by Stefaan Verhulst

Ricard Espelt and Monica Garriga  at Open Democracy: “The impact of digital platforms in recent years affects all areas and all sorts of organizations: from production to consumption, from political parties to social movements, from business to public administration, trade unions, universities or the mass media. The disruption they generate is cross-section and intergenerational. Undoubtedly, their outstanding assets – at least from a discursive point of view –, are self-management and disintermediation. Today, through technology, people can participate actively in processes related to any particular activity. This is why we often talk about digital platforms as tools for democratizing participation, overcoming as they do the traditional tyranny of space and time. If we analyze them in detail, however, and look at the organizations that promote them, we realize that the improvement in citizen involvement tends to vary, sometimes considerably, as does the logic behind their approach…..

La Teixidora, a democratic digital platform

Being aware now of the risks of partial evaluation of the impact of technology and the key elements to be considered in analyzing it, let us return to our starting point: democratizing participation. Given the importance of local assessment of global digital tools, let us now see the case of the multimedia platform La Teixidora, which allows us to synthesize the aspects which, in our opinion, shape democratic participation.

Platform cooperativism or open cooperativism, whether it focuses on the social strength of cooperative values or on the need to reappropriate common goods, calls for a detailed critical review of the local activity of its digital platforms.

This initiative, launched in 2016 in Barcelona, organizes in real time a collaborative structure with the aim of mapping distributed knowledge generated in different parts of the city during conferences, meetings, workshops and other offline meeting formats related to technopolitics and the commons. To do this, it appropriates several open source tools (collaborative editor, wiki, content storage spaces) and uses a Creative Commons license which, while recognizing authorship, allows anyone to adapt the contents and even use them commercially. Two significant apps illustrate the value of its functionalities in relation to democratizing participation:

  1. In March 2016 La Teixidora covered, with a team of some twenty people, a debate on Collaborative Economy (Economies Col·laboratives Procomuns). The classified data were then transferred to the Decidim Barcelona platform, which has helped to define, through a broad participatory process, the Municipal Action Plan of the Barcelona City Council.
  2. At the same time, the tool has been used to monitor the fifteen teams which have been following the economic development program La Comunificadora, whose aim is the promotion of social transformation projects and the advancement of entrepreneurship. Through La Teixidora, the participants have been able to establish a space for exchanging knowledge among them, with the mentors, with the city service managers and with citizens in general. All its contents are open and reusable.

In short, through this platform, both processes have been able not only to contribute proposals, but also to form an open learning space. And by mapping participation, which makes these processes – both of which are promoted by the Public Administration – transparent and accountable, thus improving their democratic quality. At the same time, the information and the learning from their use are helping to redesign the technological platform itself and adapt it to the needs of the communities involved….(More)”.

Open Data Barometer 2016

Curated on Posted on by Stefaan Verhulst

Open Data Barometer: “Produced by the World Wide Web Foundation as a collaborative work of the Open Data for Development (OD4D) network and with the support of the Omidyar Network, the Open Data Barometer (ODB) aims to uncover the true prevalence and impact of open data initiatives around the world. It analyses global trends, and provides comparative data on countries and regions using an in-depth methodology that combines contextual data, technical assessments and secondary indicators.

Covering 115 jurisdictions in the fourth edition, the Barometer ranks governments on:

  • Readiness for open data initiatives.
  • Implementation of open data programmes.
  • Impact that open data is having on business, politics and civil society.

After three successful editions, the fourth marks another step towards becoming a global policymaking tool with a participatory and inclusive process and a strong regional focus. This year’s Barometer includes an assessment of government performance in fulfilling the Open Data Charter principles.

The Barometer is a truly global and collaborative effort, with input from more than 100 researchers and government representatives. It takes over six months and more than 10,000 hours of research work to compile. During this process, we address more than 20,000 questions and respond to more than 5,000 comments and suggestions.

The ODB global report is a summary of some of the most striking findings. The full data and methodology is available, and is intended to support secondary research and inform better decisions for the progression of open data policies and practices across the world…(More)”.

Neutralizing misinformation through inoculation: Exposing misleading argumentation techniques reduces their influence

Curated on Posted on by Stefaan Verhulst

Paper by John Cook, Stephan Lewandowsky, and Ullrich K. H. Ecker in PLOS: “Misinformation can undermine a well-functioning democracy. For example, public misconceptions about climate change can lead to lowered acceptance of the reality of climate change and lowered support for mitigation policies. This study experimentally explored the impact of misinformation about climate change and tested several pre-emptive interventions designed to reduce the influence of misinformation. We found that false-balance media coverage (giving contrarian views equal voice with climate scientists) lowered perceived consensus overall, although the effect was greater among free-market supporters. Likewise, misinformation that confuses people about the level of scientific agreement regarding anthropogenic global warming (AGW) had a polarizing effect, with free-market supporters reducing their acceptance of AGW and those with low free-market support increasing their acceptance of AGW. However, we found that inoculating messages that (1) explain the flawed argumentation technique used in the misinformation or that (2) highlight the scientific consensus on climate change were effective in neutralizing those adverse effects of misinformation. We recommend that climate communication messages should take into account ways in which scientific content can be distorted, and include pre-emptive inoculation messages….(More)”

Internet of Things: Status and implications of an increasingly connected world

Curated on Posted on by Stefaan Verhulst

GAO Technology Assessment: “The Internet of Things (IoT) refers to the technologies and devices that sense information and communicate it to the Internet or other networks and, in some cases, act on that information. These “smart” devices are increasingly being used to communicate and process quantities and types of information that have never been captured before and respond automatically to improve industrial processes, public services, and the well-being of individual consumers. For example, a “connected” fitness tracker can monitor a user’s vital statistics, and store the information on a smartphone. A “smart” tractor can use GPS-based driving guidance to maximize crop planting or harvesting. Electronic processors and sensors have become smaller and less costly, which makes it easier to equip devices with IoT capabilities. This is fueling the global proliferation of connected devices, allowing new technologies to be embedded in millions of everyday products. The IoT’s rapid emergence brings the promise of important new benefits, but also presents potential challenges such as the following:

  • Information security. The IoT brings the risks inherent in potentially unsecured information technology systems into homes, factories, and communities. IoT devices, networks, or the cloud servers where they store data can be compromised in a cyberattack. For example, in 2016, hundreds of thousands of weakly-secured IoT devices were accessed and hacked, disrupting traffic on the Internet.
  • Privacy. Smart devices that monitor public spaces may collect information about individuals without their knowledge or consent. For example, fitness trackers link the data they collect to online user accounts, which generally include personally identifiable information, such as names, email addresses, and dates of birth. Such information could be used in ways that the consumer did not anticipate. For example, that data could be sold to companies to target consumers with advertising or to determine insurance rates.
  • Safety. Researchers have demonstrated that IoT devices such as connected automobiles and medical devices can be hacked, potentially endangering the health and safety of their owners. For example, in 2015, hackers gained remote access to a car through its connected entertainment system and were able to cut the brakes and disable the transmission.
  • Standards. IoT devices and systems must be able to communicate easily. Technical standards to enable this communication will need to be developed and implemented effectively.
  • Economic issues. While impacts such as positive growth for industries that can use the IoT to reduce costs and provide better services to customers are likely, economic disruptions are also possible, such as reducing the need for certain types of businesses and jobs that rely on individual interventions, including assembly line work or commercial vehicle deliveries…(More)”

Using Facebook Ads Audiences for Global Lifestyle Disease Surveillance: Promises and Limitations

Curated on Posted on by Stefaan Verhulst

Paper by Matheus Araujo et al at ArXiv: “Every day, millions of users reveal their interests on Facebook, which are then monetized via targeted advertisement marketing campaigns. In this paper, we explore the use of demographically rich Facebook Ads audience estimates for tracking non-communicable diseases around the world. Across 47 countries, we compute the audiences of marker interests, and evaluate their potential in tracking health conditions associated with tobacco use, obesity, and diabetes, compared to the performance of placebo interests. Despite its huge potential, we €find that, for modeling prevalence of health conditions across countries, di‚fferences in these interest audiences are only weakly indicative of the corresponding prevalence rates. Within the countries, however, our approach provides interesting insights on trends of health awareness across demographic groups. Finally, we provide a temporal error analysis to expose the potential pitfalls of using Facebook’s Marketing API as a black box…(More)”.

How Technology Can Help Solve Societal Problems

Curated on Posted on by Stefaan Verhulst

Barry Libert, Megan Beck, Brian Komar and Josue Estrada at Knowledge@Wharton: “…nonprofit groups, academic institutions and philanthropic organizations engaged in social change are struggling to adapt to the new global, technological and virtual landscape.

Legacy modes of operation, governance and leadership competencies rooted in the age of physical realities continue to dominate the space. Further, organizations still operate in internal and external silos — far from crossing industry lines, which are blurring. And their ability to lead in a world that is changing at an exponential rate seems hampered by their mental models and therefore their business models of creating and sustaining value as well.

If civil society is not to get drenched and sink like a stone, it must start swimming in a new direction. This new direction starts with social organizations fundamentally rethinking the core assumptions driving their attitudes, behaviors and beliefs about creating long-term sustainable value for their constituencies in an exponentially networked world. Rather than using an organization-centric model, the nonprofit sector and related organizations need to adopt a mental model based on scaling relationships in a whole new way using today’s technologies — the SCaaP model.

Embracing social change as a platform is more than a theory of change, it is a theory of being — one that places a virtual network or individuals seeking social change at the center of everything and leverages today’s digital platforms (such as social media, mobile, big data and machine learning) to facilitate stakeholders (contributors and consumers) to connect, collaborate, and interact with each other to exchange value among each other to effectuate exponential social change and impact.

SCaaP builds on the government as a platform movement (Gov 2.0) launched by technologist Tim O’Reilly and many others. Just as Gov 2.0 was not about a new kind of government but rather, as O’Reilly notes, “government stripped down to its core, rediscovered and reimagined as if for the first time,” so it is with social change as a platform. Civil society is the primary location for collective action and SCaaP helps to rebuild the kind of participatory community celebrated by 19th century French historian Alexis de Tocqueville when he observed that Americans’ propensity for civic association is central to making our democratic experiment work. “Americans of all ages, all stations in life, and all types of disposition,” he noted, “are forever forming associations.”

But SCaaP represents a fundamental shift in how civil society operates. It is grounded in exploiting new digital technologies, but extends well beyond them to focus on how organizations think about advancing their core mission — do they go at it alone or do they collaborate as part of a network? SCaaP requires thinking and operating, in all things, as a network. It requires updating the core DNA that runs through social change organizations to put relationships in service of a cause at the center, not the institution. When implemented correctly, SCaaP will impact everything — from the way an organization allocates resources to how value is captured and measured to helping individuals achieve their full potential….(More)”.
