David C. Roberts at Quartz: “Every year, outdoor air pollution kills more people worldwide than malaria and HIV combined. People in China, particularly in its largest cities, are some of the most affected, since the country’s rapid economic growth has come at the cost of air quality. This issue remained largely unaddressed until the US embassy in Beijing began to tweet out air quality data in 2008, providing a remarkable demonstration of the transformative power of democratizing data. The tweets sparked an energetic environmental movement that forced China’s leaders to acknowledge the massive scale of the problem and begin to take measures to combat it.
The initiative to publicize air quality data was subsequently expanded to US consulates in several major Chinese cities, providing a wealth of new scientific data. I recently worked with Federico San Martini and Christa Hasenkopf (both atmospheric scientists at the US State Department who are involved in this program) to analyze this data…(More)”
Sumana Harihareswara at code4lib: “…Before I worked in open source, I worked in customer service. I saw first-hand how design flaws (in architecture, signage, and websites) could frustrate and drive away customers and make more work for me. Every time I participated in an open source project — AltLaw, GNOME, MediaWiki, and more — I’ve brought that experience with me. I found it particularly striking that small changes on Wikipedia could cause large changes in user behavior, as I discuss in this essay, which is adapted from my keynote speech.
This issue goes beyond software, as I explain with the healthcare and banking examples. The spark that caused me to write the speech was reading Professor Lisa J. Servon’s piece in The Atlantic about the usability of storefront check cashing services; I saw a pattern where poor user experience repels people from crucial and empowering services, and decided, in a flash of anger and inspiration, to write “User Experience is a Human Rights Issue.”…
The Last Mile Problem
The largest hurdles we as technologists face are choosing to make the right things in the first place and choosing to make them usable. In the 1990’s, telecommunications companies laid down a lot of fiber to connect big hubs to one another, but often it took years to connect those hubs to the actual houses and schools and shops and offices, because it was expensive, or because companies were not creative enough to do it well. This is called the “last mile problem,” and I think usability has a similar problem. We have to be creative and disciplined enough to actually provide services in a way that people can use them.
When we’re building services for people, we often have a lot more practice seeing things from the computer’s point of view or from the data’s point of view than from another person’s point of view. In tech, we understand how to build arteries better than we understand how to build capillaries. Personally, I think capillaries are more interesting than arteries. Maybe it’s just personal temperament, but I like all the little surprising details of how people end up experiencing the ripple effects of big new systems, and how users actually interact with the user interface of a service, especially ones that we don’t really think of as having a user interface. Like taxes, or healthcare, or hotels. All these big systems end in little capillaries, where people exchange information or get healed or get whatever they need. And when those capillaries aren’t working correctly, then those people just don’t get what they need. The hubs are connected to each other, but people aren’t connected to the hubs.
Over and over, in lots of different fields, we see that bad usability makes a huge difference. When choosing between two services, people will make very different choices, depending on which service actually seems designed around the user’s needs….(More)”
“…the GovLab is pleased to announce the beta release of the NETmundial Solutions Map for further public comment (from April 1 -May 1, 2015). The release is the culmination of a 6-month engagement and development strategy to ensure that the tool reflects input from a diverse set of global stakeholders. The NETmundial Solutions Map is co-developed by the GovLab and Second Rise, and is facilitated by the Internet Corporation for Assigned Names and Numbers (ICANN).
The tool seeks to support innovation in global governance toward a more distributed Internet Governance approach. It is designed to enable information sharing and collaboration across Internet governance issues. It will serve as a repository of information that links issues, actors, solutions and resources, and help users understand the current landscape of Internet governance.
Today, information about internet governance is scattered and hard to find. At the same time we need more coordination and collaboration to address specific issues. The Map seeks to facilitate a more collaborative and distributed way of solving Internet governance issues by providing users with a baseline of what responses already exist and who is working on what — Stefaan Verhulst, Co-Founder and Chief of Research and Development of the GovLab.
..This beta version of the NETmundial Solutions Map seeks to explore how to map the Internet governance landscape in a useful and sustainable way. Future revisions will continue to be guided by community feedback.
New book by Dirk Helbing: “The rapidly progressing digital revolution is now touching the foundations of the governance of societal structures. Humans are on the verge of evolving from consumers to prosumers, and old, entrenched theories – in particular sociological and economic ones – are falling prey to these rapid developments. The original assumptions on which they are based are being questioned. Each year we produce as much data as in the entire human history – can we possibly create a global crystal ball to predict our future and to optimally govern our world? Do we need wide-scale surveillance to understand and manage the increasingly complex systems we are constructing, or would bottom-up approaches such as self-regulating systems be a better solution to creating a more innovative, more successful, more resilient, and ultimately happier society? Working at the interface of complexity theory, quantitative sociology and Big Data-driven risk and knowledge management, the author advocates the establishment of new participatory systems in our digital society to enhance coordination, reduce conflict and, above all, reduce the “tragedies of the commons,” resulting from the methods now used in political, economic and management decision-making….(More)”
Paper by Brinker, David and Gastil, John and Richards, Robert C. in the Journal of Computer-Mediated Communication (Forthcoming): “Public deliberation on the Internet is a promising but unproven practice. Online deliberation can engage large numbers of citizens at relatively low cost, but it is unclear whether such programs have substantial civic impact. One factor in determining their effectiveness may be the communicative features of the online setting in which they occur. Within a Media Richness Theory framework, we conducted a quasi-experiment to assess the civic outcomes of interventions executed online by non-profit organizations prior to the 2012 U.S. presidential election. The results assess the impact of these interventions on issue knowledge and civic attitudes. Comparisons of the interventions illustrate the importance of considering media richness online, and our discussion considers the theoretical and practical implications of these findings….(More)”
BioMedCentral Blog: ” The 5th Annual Oxford London Lecture (17 March 2015) was delivered by Professor Susan Jebb from Oxford University. The presentation was titled: ‘Knowledge, nudge and nanny: Opportunities to improve the nation’s diet’. In this guest blog Dr Helen Walls, Research Fellow at the London School of Hygiene and Tropical Medicine, covers key themes from this presentation.
“Obesity and related non-communicable disease such as diabetes, heart disease and cancer poses a significant health, social and economic burden in countries worldwide, including the United Kingdom. Whilst the need for action is clear, the nutrition policy response is a highly controversial topic. Professor Jebb raised the question of how best to achieve dietary change: through ‘knowledge, nudge or nanny’?
Education regarding healthy nutrition is an important strategy, but insufficient. People are notoriously bad at putting their knowledge to work. The inclination to overemphasise the importance of knowledge, whilst ignoring the influence of environmental factors on human behaviours, is termed the ‘fundamental attribution error’. Education may also contribute to widening inequities.
Our choices are strongly shaped by the environments in which we live. So if ‘knowledge’ is not enough, what sort of interventions are appropriate? This raises questions regarding individual choice and the role of government. Here, Professor Jebb introduced the Nuffield Intervention Ladder.
Nuffield Intervention Ladder
Nuffield Council on Bioethics. Public health ethical issues. London: Nuffield Council on Bioethics. 2007.
The Nuffield Intervention Ladder or what I will refer to as ‘the ladder’ describes intervention types from least to most intrusive on personal choice. With addressing diets and obesity, Professor Jebb believes we need a range of policy types, across the range of rungs on the ladder.
Less intrusive measures on the ladder could include provision of information about healthy and unhealthy foods, and provision of nutritional information on products (which helps knowledge be put into action). More effective than labelling is the signposting of healthier choices.
Taking a few steps up the ladder brings in ‘nudge’, a concept from behavioural economics. A nudge is any aspect of the choice architecture that alters people’s behaviour in a predictable way without forbidding options or significantly changing economic incentives. Nudges are not mandates. Putting fruit at eye level counts as a nudge. Banning junk food does not.
Nudges are not mandates. Putting fruit at eye level counts as a nudge. Banning junk food does not.
The in-store environment has a huge influence over our choices, and many nudge options would fit here. For example, gondalar-end (end of aisle) promotions create a huge up-lift in sales. Removing unhealthy products from this position could make a considerable difference to the contents of supermarket baskets.
Nudge could be used to assist people make better nutritional choices, but it’s also unlikely to be enough. We celebrate the achievement we have made with tobacco control policies and smoking reduction. Here, we use a range of intervention types, including many legislative measures – the ‘nanny’ aspect of the title of this presentation….(More)”
Review by Michael Czerny: “Sentiment analysis is a common application of Natural Language Processing (NLP) methodologies, particularly classification, whose goal is to extract the emotional content in text. In this way, sentiment analysis can be seen as a method to quantify qualitative data with some sentiment score. While sentiment is largely subjective, sentiment quantification has enjoyed many useful implementations, such as businesses gaining understanding about consumer reactions to a product, or detecting hateful speech in online comments.
The simplest form of sentiment analysis is to use a dictionary of good and bad words. Each word in a sentence has a score, typically +1 for positive sentiment and -1 for negative. Then, we simply add up the scores of all the words in the sentence to get a final sentiment total. Clearly, this has many limitations, the most important being that it neglects context and surrounding words. For example, in our simple model the phrase “not good” may be classified as 0 sentiment, given “not” has a score of -1 and “good” a score of +1. A human would likely classify “not good” as negative, despite the presence of “good”.
Another common method is to treat a text as a “bag of words”. We treat each text as a 1 by N vector, where N is the size of our vocabulary. Each column is a word, and the value is the number of times that word appears. For example, the phrase “bag of bag of words” might be encoded as [2, 2, 1]. This could then be fed into a machine learning algorithm for classification, such as logistic regression or SVM, to predict sentiment on unseen data. Note that this requires data with known sentiment to train on in a supervised fashion. While this is an improvement over the previous method, it still ignores context, and the size of the data increases with the size of the vocabulary.
Word2Vec and Doc2Vec
Recently, Google developed a method called Word2Vec that captures the context of words, while at the same time reducing the size of the data. Word2Vec is actually two different methods: Continuous Bag of Words (CBOW) and Skip-gram. In the CBOW method, the goal is to predict a word given the surrounding words. Skip-gram is the converse: we want to predict a window of words given a single word (see Figure 1). Both methods use artificial neural networks as their classification algorithm. Initially, each word in the vocabulary is a random N-dimensional vector. During training, the algorithm learns the optimal vector for each word using the CBOW or Skip-gram method….(More)“
Jill Lepore about Magna Carta, the Bill of Rights, and the hold of time in The New Yorker: “…Magna Carta has been taken as foundational to the rule of law, chiefly because in it King John promised that he would stop throwing people into dungeons whenever he wished, a provision that lies behind what is now known as due process of law and is understood not as a promise made by a king but as a right possessed by the people. Due process is a bulwark against injustice, but it wasn’t put in place in 1215; it is a wall built stone by stone, defended, and attacked, year after year. Much of the rest of Magna Carta, weathered by time and for centuries forgotten, has long since crumbled, an abandoned castle, a romantic ruin.
Magna Carta is written in Latin. The King and the barons spoke French. “Par les denz Dieu!” the King liked to swear, invoking the teeth of God. The peasants, who were illiterate, spoke English. Most of the charter concerns feudal financial arrangements (socage, burgage, and scutage), obsolete measures and descriptions of land and of husbandry (wapentakes and wainages), and obscure instruments for the seizure and inheritance of estates (disseisin and mort d’ancestor). “Men who live outside the forest are not henceforth to come before our justices of the forest through the common summonses, unless they are in a plea,” one article begins.
Magna Carta’s importance has often been overstated, and its meaning distorted. “The significance of King John’s promise has been anything but constant,” U.S. Supreme Court Justice John Paul Stevens aptly wrote, in 1992. It also has a very different legacy in the United States than it does in the United Kingdom, where only four of its original sixty-some provisions are still on the books. In 2012, three New Hampshire Republicans introduced into the state legislature a bill that required that “all members of the general court proposing bills and resolutions addressing individual rights or liberties shall include a direct quote from the Magna Carta which sets forth the article from which the individual right or liberty is derived.” For American originalists, in particular, Magna Carta has a special lastingness. “It is with us every day,” Justice Antonin Scalia said in a speech at a Federalist Society gathering last fall.
Much has been written of the rule of law, less of the rule of history. Magna Carta, an agreement between the King and his barons, was also meant to bind the past to the present, though perhaps not in quite the way it’s turned out. That’s how history always turns out: not the way it was meant to. In preparation for its anniversary, Magna Carta acquired a Twitter username: @MagnaCarta800th….(More)”
Paper by Michael Curtotti, Wayne Weibel, Eric McCreath, Nicolas Ceynowa, Sara Frug, and Tom R Bruce: “This paper sits at the intersection of citizen access to law, legal informatics and plain language. The paper reports the results of a joint project of the Cornell University Legal Information Institute and the Australian National University which collected thousands of crowdsourced assessments of the readability of law through the Cornell LII site. The aim of the project is to enhance accuracy in the prediction of the readability of legal sentences. The study requested readers on legislative pages of the LII site to rate passages from the United States Code and the Code of Federal Regulations and other texts for readability and other characteristics. The research provides insight into who uses legal rules and how they do so. The study enables conclusions to be drawn as to the current readability of law and spread of readability among legal rules. The research is intended to enable the creation of a dataset of legal rules labelled by human judges as to readability. Such a dataset, in combination with machine learning, will assist in identifying factors in legal language which impede readability and access for citizens. As far as we are aware, this research is the largest ever study of readability and usability of legal language and the first research which has applied crowdsourcing to such an investigation. The research is an example of the possibilities open for enhancing access to law through engagement of end users in the online legal publishing environment for enhancement of legal accessibility and through collaboration between legal publishers and researchers….(More)”
IEEE Spectrum: “Fifty years ago this month, Gordon Moore forecast a bright future for electronics. His ideas were later distilled into a single organizing principle—Moore’s Law—that has driven technology forward at a staggering clip. We have all benefited from this miraculous development, which has forcefully shaped our modern world.
In this special report, we find that the end won’t be sudden and apocalyptic but rather gradual and complicated. Moore’s Law truly is the gift that keeps on giving—and surprising, as well….(More)”
