Dynamics and Logics of Civil War
This article reviews the literature on civil war. We focus on the most recent period of scholarly activity, beginning in the early 2000s when the publication of prominent quantitative studies triggered a surge in the empirical research of civil war as a well-defined conceptual category. We identify three explanatory logics that have dominated much of this literature and that view civil wars as a consequence of greed, grievances, and opportunities, respectively. We evaluate the arguments and findings of these theoretical approaches with respect to each of the main phases of war: outbreak, wartime dynamics, conflict termination, and postwar recovery. The article concludes by identifying key challenges confronting future civil war research. In particular, we emphasize the continuing need to advance theories that bridge the main explanatory logics as well as the different phases of conflict. Researchers should also pay more attention to defining the appropriate spatiotemporal scope of their studies
Triangulating Horizontal Inequality: Towards Improved Conflict Analysis.
Does economic inequality cause civil war? Deviating from individualist measures of inequality such as the Gini coefficient, recent studies have found a statistical link between group-level inequalities and conflict onset. Yet, this connection remains controversial, not least because of the difficulties associated with conceptualizing and measuring group-level differences in development. In an effort to overcome weaknesses afflicting specific methods of measurement, we introduce a new composite indicator that exploits the strengths of three sources of data. The first step of our method combines geocoded data from the G-Econ project with night lights emissions data from satellites. In a second step, we bring together the combined spatial values with survey estimates in order to arrive at an improved measure of group-level inequality that is both more accurate and robust than any one of the component measures. We evaluate the effect of the combined indicator and its components on the onset of civil violence. As expected, the combined index yields stronger results as more information becomes available, thus confirming the initial hypothesis that horizontal economic inequality does drive conflict in the case of groups that are relatively poorer compared to the country average. Furthermore, these findings appear to be considerably more robust than those relying on a single data source.Swiss National Science FoundationAlexander von Humboldt Foundatio
Integrating Data on Ethnicity, Geography, and Conflict: The Ethnic Power Relations Dataset Family.
ArticleThis article introduces the new Family of Ethnic Power Relations (EPR) data sets, version 2014, which is the latest in a series of data sets on ethnicity that have stimulated civil war research in the past decade. The EPR Family provides data on ethnic groups’ access to state power, their settlement patterns, links to rebel organizations, transborder ethnic kin relations, and intraethnic cleavages. The new 2014 version does not only extend the data set’s temporal coverage from 2009 to 2013, but it also offers several new features, such as a new measure of regional autonomy that is independent of national-level executive power and a new data set component coding intraethnic identities and cleavages. Moreover, for the first time, detailed documentation of the EPR data is provided through the EPR Atlas. This article presents these novelties in detail and compares the EPR Family 2014 to the most relevant alternative data sets on ethnicity.Swiss National Science FoundationSwiss Agency for Development and Cooperation (SDC

A Universal Model of Global Civil Unrest
Civil unrest is a powerful form of collective human dynamics, which has led
to major transitions of societies in modern history. The study of collective
human dynamics, including collective aggression, has been the focus of much
discussion in the context of modeling and identification of universal patterns
of behavior. In contrast, the possibility that civil unrest activities, across
countries and over long time periods, are governed by universal mechanisms has
not been explored. Here, we analyze records of civil unrest of 170 countries
during the period 1919-2008. We demonstrate that the distributions of the
number of unrest events per year are robustly reproduced by a nonlinear,
spatially extended dynamical model, which reflects the spread of civil disorder
between geographic regions connected through social and communication networks.
The results also expose the similarity between global social instability and
the dynamics of natural hazards and epidemics.Comment: 8 pages, 3 figure
A wider Europe? The view from Russia, Belarus and Ukraine
On the evidence of national surveys conducted between 2000 and 2006, there is a declining sense of European self-identity in the three Slavic post-Soviet republics of Russia, Belarus and Ukraine. Attitudes towards the European Union and the possibility of membership are broadly supportive, but with a substantial proportion who find it difficult to express a view, and substantial proportions are poorly informed in comparison with the general public in EU member or prospective member countries. Those who are better informed are more likely to favour EU membership and vice versa. Generally, socioeconomic characteristics (except for age and region) are relatively poor predictors of support for EU membership as compared with attitudinal variables. But ‘Europeanness’ should not be seen as a given, and much will depend on whether EU member countries emphasize what is common to east and west or establish ‘new dividing lines’ in place of those of the cold war
Nonequilibrium phase transition due to social group isolation
We introduce a simple model of a growing system with competing
communities. The model corresponds to the phenomenon of defeats suffered by
social groups living in isolation. A nonequilibrium phase transition is
observed when at critical time the first isolated cluster occurs. In the
one-dimensional system the volume of the new phase, i.e. the number of the
isolated individuals, increases with time as . For a large number
of possible communities the critical density of filled space equals to where is the system size. A similar transition is observed
for Erd\H{o}s-R\'{e}nyi random graphs and Barab\'{a}si-Albert scale-free
networks. Analytic results are in agreement with numerical simulations.Comment: 5 pages, 4 figure
Human group formation in online guilds and offline gangs driven by common team dynamic
Quantifying human group dynamics represents a unique challenge. Unlike
animals and other biological systems, humans form groups in both real (offline)
and virtual (online) spaces -- from potentially dangerous street gangs
populated mostly by disaffected male youths, through to the massive global
guilds in online role-playing games for which membership currently exceeds tens
of millions of people from all possible backgrounds, age-groups and genders. We
have compiled and analyzed data for these two seemingly unrelated offline and
online human activities, and have uncovered an unexpected quantitative link
between them. Although their overall dynamics differ visibly, we find that a
common team-based model can accurately reproduce the quantitative features of
each simply by adjusting the average tolerance level and attribute range for
each population. By contrast, we find no evidence to support a version of the
model based on like-seeking-like (i.e. kinship or `homophily')

Exploring the topology of the plausible: Fs/QCA counterfactual analysis and the plausible fit of unobserved organizational configurations
The main aim of this contribution is to expand the dominant rationale of organizational design research by including solutions and possibilities not observed in reality. We believe that the
counterfactual approach to configurations responds to an open call in organization theory and strategy to move the modelling of fit towards a more robust and theory-based specification. With this new approach we propose to rediscover the roots of organization design as a distinct normative discipline that ‘should stand approximately in relation to the basic social sciences as engineering stands with respect to physical sciences or medicine to the biological’. At a more general level, our view implies an expansion of the dominant meaning of the concept of ‘relevance’ in management research. While we agree with Gulati (2007: 780) that we as scholars should probe ‘more deeply into the problems and other issues that managers care about’, we also believe that relevance does not necessarily mean that researchers have to use an ex-post rationality by studying only empirically frequent phenomena. In contrast, we think that any management esearcher should bring with her or himself a fragment of the spirit
of the great Greek philosopher Anaximander (c. 610–c. 546 BC), who foresaw the concept of the infinite universe without the support of any empirical observation and against the predominant
wisdom of the time. Not by chance, Karl Popper (1998) onsidered Anaximander’s intuitions among the most vivid demonstrations of the power of human thought and logic
Correlations and forecast of death tolls in the Syrian conflict
The Syrian armed conflict has been ongoing since 2011 and has already caused thousands of deaths. The analysis of death tolls helps to understand the dynamics of the conflict and to better allocate resources and aid to the affected areas. In this article, we use information on the daily number of deaths to study temporal and spatial correlations in the data, and exploit this information to forecast events of deaths. We found that the number of violent deaths per day in Syria varies more widely than that in England in which non-violent deaths dominate. We have identified strong positive auto-correlations in Syrian cities and non-trivial cross-correlations across some of them. The results indicate synchronization in the number of deaths at different times and locations, suggesting respectively that local attacks are followed by more attacks at subsequent days and that coordinated attacks may also take place across different locations. Thus the analysis of high temporal resolution data across multiple cities makes it possible to infer attack strategies, warn potential occurrence of future events, and hopefully avoid further deaths
