Map networks of major cities according to communication patterns, the size of the nodes indicate network centrality under a targeted search. Washington DC, New York, Bratislava, London and Stockholm, the 5 cities featured in the Tag Challenge, are marked in black.
A representation of the incidence of mosquito born diseases in Colombia in 2014 in the style of Peter Saville's classic design for Joy Division's Unknown Pleasures. Joint work by myself and Manuel Garcia-Herranz
A document similarity network based on national constitutions. Each node represents a country and are coloured according to network community decomposition. Each colour corresponds to family of constitutions that are influenced and share similar language.
Time series of adoption of constitutional provisions over time. Provisions cluster into 4 families according to their behaviour between World War I and II and the collapse of the Soviet Union.
A heat map of propensity to violence in Switzerland based on spatial analysis of ethnic groups. The left hand image is the violence in the absence of physical barriers and the right hand image with their mitigating effect
A representation of the hierarchy of adoption of provisions. Provisions related to work are identified, for example 'The right to join a trade union' is adopted before 'Limits in the employment of children' hinting at a roadmap to effective advocacy for children. Blue lines are network edges point down the hierarchy and red edges violate the hierarchy.
A time series plot of constitutional amendments. The colours represent 4 distinct families of constitutions (French, Iberian, Commonwealth and ex-Soviet). Remarkably, strong correlations are seen in this amendment activity.
A representation of the preferred language of social media users against the language used in their own content. Languages detected using langid.
A representation of the prevalence of mosquito borne diseases in Colombia.
A time series of the growth in adoption of constitutional provisions with respect to the growth in independent countries with a national constitution. A separation is seen between provisions adopted favourably at a specific point in time and those preferentially adopted between clusters of countries influenced by one another. (see Constitutionology)
The number of Autonomous Systems, components of the internet backbone roughly proportional to the number of organisations providing IP addresses, per capita by country. The number of AS's per capita strongly reflect the level of development, with North Korea and South Korea representing the low and high extremes respectively. This analysis is described in a Github repository.
A map of the world coloured according to countries with similar constitutions. The clusters emerge based on linguistic similarity. (see Constitutionology)
How do people post tweets in different countries? The source field in Twtter data reveals which device or service was used to post content. This blog post describes the differences in devices in Kenya, Nigeria, India and Pakistan.
A map of population density in the continental United States overlaid with the locations of the balloons in the DARPA Balloon Challenge forming the basis of Limits of Social Mobilisation
An analysis of the complexity of terrain in Afghanistan, white areas represent regions of low complexity and blue/black regions of high terrain complexity more amenable to insurgent activity.
Comparison of the location of cell towers in Brazil compared to a generative algorithm to optimally place cell towers based on high resolutoin population density, developed with Manuel Garcia-Herranz and described here.
