What can we learn about Somalis from their Facebook networks?

After the initial focus on the Somali dominated economy and social structure of Eastleigh, I hoped to contribute additional material to the project by mapping out the online social networks of Somalis (or at least as many as I could convince to grant me access to their network data). I hoped such material would add a quantitative element to the oral reports of geographically distributed … Continue reading What can we learn about Somalis from their Facebook networks?

The Relentless Pace of Automation

Last October, Uber had one of its self-­driving trucks make a beer run, traveling 200 kilometers down the interstate to deliver a cargo of Budweiser from Fort Collins to Colorado Springs. A person rode in the truck but spent most of the trip in the sleeper berth, monitoring the automated system. (The test came just a few weeks after Uber had announced its driverless car … Continue reading The Relentless Pace of Automation

Understanding statistical ways…

Humans have a bias for turning to the right in a number of settings. Here we document a bias in head-turning to the right in adult humans, as tested in the act of kissing. We investigated head-turning bias in both kiss initiators and kiss recipients for lip kissing, and took into consideration differences due to sex and handedness, in 48 Bangladeshi heterosexual married couples. We … Continue reading Understanding statistical ways…

Understanding of p-hacking

Data dredging (also data fishing, data snooping, and p-hacking) is the use of data mining to uncover patterns in data that can be presented as statistically significant, without first devising a specific hypothesis as to the underlying causality. The process of data dredging involves automatically testing huge numbers of hypotheses about a single data set by exhaustively searching — perhaps for combinations of variables that … Continue reading Understanding of p-hacking

Beyond opening up the black box: Investigating the role of algorithmic systems in Wikipedian organizational culture

Scholars and practitioners across domains are increasingly concerned with algorithmic transparency and opacity, interrogating the values and assumptions embedded in automated, black-boxed systems, particularly in user-generated content platforms. I report from an ethnography of infrastructure in Wikipedia to discuss an often understudied aspect of this topic: the local, contextual, learned expertise involved in participating in a highly automated social–technical environment. Today, the organizational culture of … Continue reading Beyond opening up the black box: Investigating the role of algorithmic systems in Wikipedian organizational culture

The World of Music: SDP layout of high dimensional data

The researchers used a technique called semidefinite programming (which is sometimes called Semidefinite embedding) to … Continue reading The World of Music: SDP layout of high dimensional data

Traditional Values and Political Trust in ChinaJournal of Asian and African Studies – Yida Zhai, 2016

Chinese traditional culture is viewed to sustain political trust in the authoritarian regime. Given that Chinese cultural traditions are complex and multi-dimensional, it is ineffective to deal with this notion by a single index. This study divides Chinese traditional values into a non-political dimension (traditional family and social values) and a political dimension (traditional political values). Then, I empirically test how different dimensions of Chinese … Continue reading Traditional Values and Political Trust in ChinaJournal of Asian and African Studies – Yida Zhai, 2016

Blackbox of surveilling French Internet

« Boîtes noires ». Le terme avait suscité un torrent de critiques au moment des discussions autour de la loi sur le renseignement, début 2015. Ces algorithmes, qui permettent de traiter de grandes quantités de données dans le but de détecter des « signaux faibles » pour lutter contre la « menace terroriste », sont aujourd’hui en cours de déploiement. C’est le président de la Commission nationale de contrôle des … Continue reading Blackbox of surveilling French Internet

BotOrNot: A System to Evaluate Social Bots

While most online social media accounts are controlled by humans, these platforms also host automated agents called social bots or sybil accounts. Recent literature reported on cases of social bots imitating humans to manipulate discussions, alter the popularity of users, pollute content and spread misinformation, and even perform terrorist propaganda and recruitment actions. Here we present BotOrNot, a publicly-available service that leverages more than one … Continue reading BotOrNot: A System to Evaluate Social Bots

Accountability of AI Under the Law

The ubiquity of systems using artificial intelligence or “AI” has brought increasing attention to how those systems should be regulated. The choice of how to regulate AI systems will require care. AI systems have the potential to synthesize large amounts of data, allowing for greater levels of personalization and precision than ever before—applications range from clinical decision support to autonomous driving and predictive policing. That … Continue reading Accountability of AI Under the Law

Manipulating Social Media to Undermine Democracy

Governments around the world have dramatically increased their efforts to manipulate information on social media over the past year. The Chinese and Russian regimes pioneered the use of surreptitious methods to distort online discussions and suppress dissent more than a decade ago, but the practice has since gone global. Such state-led interventions present a major threat to the notion of the internet as a liberating … Continue reading Manipulating Social Media to Undermine Democracy

Iphoneography as an emergent art world

The iPhone has come to be one of the most popular and widely used cameras because of its ubiquity and the ease with which images can be uploaded directly to sites like Flickr, Facebook, and Twitter. The introduction of photography “apps,” like Hipstamatic or Instagram, adds layers of aesthetic capabilities not previously available within the camera. These capabilities have attracted artists seeking technologies for new … Continue reading Iphoneography as an emergent art world

The horse race of ideas at the finish line

For decades, news coverage of U.S. presidential elections has been focused on the so-called “horse race” — polls, predicted outcomes, fundraising — rather than on the policy issues that ultimately matter most. The Electome, a project of the Laboratory for Social Machines at the MIT Media Lab, was created with the aim of changing this. About a year ago, with generous support from the Knight Foundation and Twitter, we … Continue reading The horse race of ideas at the finish line

Is the Lone Scientist an American Dream? Perceived Communal Opportunities in STEM Offer a Pathway to Closing U.S

The United States lags behind many Asian countries in engagement in science, technology, engineering, and mathematics (STEM). An unexplored factor in these country-level differences may be U.S.–Asia gaps in perceptions of the goal opportunities provided by STEM. Across four studies, U.S. students perceived fewer communal opportunities (working with/helping/relationships with others) in STEM than Asian students; this differential perception contributed to U.S.–Asia gaps in STEM interest. … Continue reading Is the Lone Scientist an American Dream? Perceived Communal Opportunities in STEM Offer a Pathway to Closing U.S

Spatial‐Data Sharing: Applying Social‐Network Analysis to study individual and collective behaviour

Spatial‐Data Sharing (SDS) is a crucial aspect of spatial‐data infrastructures. This paper introduces Social‐Network Analysis to research on SDS. By mapping out relationships among social actors using Social‐Network Analysis, the collective properties of SDS in organizations can be investigated. Previous theoretical approaches have focused exclusively on individual behaviour. This paper attempts to expand this focus and applies Social‐Network Analysis in a study of SDS in … Continue reading Spatial‐Data Sharing: Applying Social‐Network Analysis to study individual and collective behaviour

The Zombie Diseases of Climate Change

Lately, as summers have lengthened and winters have warmed, this seasonal transformation has lost its symmetry. What biologists call the permafrost’s “active layer”—the part of the dirt where microbes and other forms of life can live—now reaches farther underground, and further north, than it has for tens of thousands of years. The newly active permafrost is packed with old stuff: dead plants, dead animals, mosses … Continue reading The Zombie Diseases of Climate Change

Lunar – a cryptocurrency hedge fund?

The financial world is currently facing what will be the biggest disruption since the creation of money itself. Institutional investors and venture capitalists will soon lose their monopoly on a market worth trillions. Hedge funds, especially, have been historically inaccessible to the average investor, with many requiring a minimum buy-in upwards of $1 Million. We aim to change that. We want to use cryptocurrency to … Continue reading Lunar – a cryptocurrency hedge fund?

Aid, China, and Growth: Evidence from a New Global Development Finance Dataset

This paper introduces a new dataset of official financing — including foreign aid and other forms of concessional and non-concessional state financing — from China to 138 countries between 2000 and 2014. We use these data to investigate whether and to what extent Chinese aid affects economic growth in recipient countries. To account for the endogeneity of aid, we employ an instrumental-variables strategy that relies … Continue reading Aid, China, and Growth: Evidence from a New Global Development Finance Dataset

Why People Get Religious about Bitcoin

The Bitcoin phenomenon isn’t about a bunch of people who all believe the cryptocurrency is a good investment. That’s part of it. But for many, the belief in Bitcoin’s power to transform society runs much deeper: it’s almost an article of faith. Where does this fervor come from? To understand, it’s important to keep in mind that “the blockchain” is not really a thing. via … Continue reading Why People Get Religious about Bitcoin

Collective intelligence for promoting changes in behavior

Climate change is one of the biggest challenges humanity faces today. Despite of high investments in technology, battling climate change is futile without the participation of the public, and changing their perception and habits. Collective intelligence tools can play an important role in translating this “distant” concept that is climate change into practical hints for everyday life. In this paper, we report a case study … Continue reading Collective intelligence for promoting changes in behavior

The shortest-lived Catalan Republic?

Barcelona, October 27, 2017. Parliament proclaims Catalonia’s independence. They end their session with a round of the Catalonian national anthem, joined by the thousands of people gathered outside. This anthem, “The Reapers,” recalls the first of several armed struggles to preserve Catalan law. After Madrid’s swift reaction last Friday to dissolve the Catalan Parliament and prosecute its presiding officer along with the region’s president and … Continue reading The shortest-lived Catalan Republic?
