Civil unrest events (protests, strikes, and “occupy” events) are common occurrences in both democracies and authoritarian regimes. The study of civil unrest is a key topic for political scientists as it helps capture an important mechanism by which citizenry express themselves. In countries where civil unrest is lawful, qualitative analysis has revealed that more than 75 percent of the protests are planned, organized, or announced in advance; therefore detecting references to future planned events in relevant news and social media is a direct way to develop a protest forecasting system. We report on a system for doing that in this article. It uses a combination of keyphrase learning to identify what to look for, probabilistic soft logic to reason about location occurrences in extracted results, and time normalization to resolve future time mentions. We illustrate the application of our system to 10 countries in Latin America: Argentina, Brazil, Chile, Colombia, Ecuador, El Salvador, Mexico, Paraguay, Uruguay, and Venezuela. Results demonstrate our successes in capturing significant societal unrest in these countries with an average lead time of 4.08 days. We also study the selective superiorities of news media versus social media (Twitter, Facebook) to identify relevant trade-offs.

This article explores the value of a specific model of norm replacement in accounting for the circumstances leading to Ireland’s Good Friday agreement (1998), which formally and finally settled the long-running territorial dispute between Ireland and the United Kingdom (UK). Drawing on the theoretical literature, it identifies three phases in this process. First, from the creation of the Irish Free State in 1922 until the civil unrest in Northern Ireland peaked in 1972 the irredentist norm was substantially unchallenged. It was embedded in the 1937 constitution, which defined the national territory as extending over the whole island of Ireland – including Northern Ireland, a part of the UK. The second phase, from about 1972 to 1998, was one of norm competition. The irredentist norm was severely challenged by new political realities in Northern Ireland, and was potentially destabilising for the state itself. It was increasingly challenged by an alternative ‘consent’ norm, one embracing in effect the geopolitical status quo. The third phase, from 1998 onwards, was one of consolidation of the new norm, now written into the Irish constitution to replace the wording of 1937. The article suggests that this model plays a valuable role in accounting for the changing status of the Irish border, but also that the Irish experience has implications for the broad shape of the model.

Syria recently suffered a once in 500-year meteorological drought followed by one of the worst conflicts of the twenty-first century. We exploit subnational variation in drought impact to examine associations between climatic stress and Syria’s political unrest. Climatic stress may produce instability through both immediate hardship and, indirectly, internal migration. Consistent with the internal migration hypothesis, we find less severely drought-stricken Syrian regions more likely to experience protest. We employ nighttime lights as a proxy for population density to examine the association between climatic stress and internal displacement. We find climatic stress decreased nighttime light intensity during the drought period. Increases in nighttime lights from 2005 to 2010 are associated with added risk of protest in Sunni Arab areas, suggesting an influx of migrants bolstered local grievances. Our findings support the internal migration hypothesis and suggest extreme climate events may impact civil unrest via geographically and temporally indirect paths.

Risk factors associated with intrauterine growth restriction (IUGR) have previously been identified, but few studies have described the relationship between IUGR and maternal stress caused by exposure to civil unrest. Here, we investigate this relationship during the Mount Elgon crisis in western Kenya between 2006 and 2008, following a period of violence. Birth weight data were compared between three hospitals in an exposed area, Mount Elgon (n=570), and one hospital in a control area, Kimilili (n=530). In a sub-analysis, the most stress exposed hospital, Bungoma West (n=211), was compared with the control hospital in Kimilili. Adjustments were made for offspring sex, gestational age and parity. The difference in mean birth weight between the most stress-exposed hospital (Bungoma West) and the control hospital (Kimilili) was 91 g after full adjustment (P=0.041). In conclusion, epidemiological data suggest a significant relationship between exposure to civil unrest and IUGR causing lower birth weight.
