This article presents the UCDP Georeferenced Event Dataset (UCDP GED). The UCDP GED is an event dataset that disaggregates three types of organized violence (state-based conflict, non-state conflict, and one-sided violence) both spatially and temporally. Each event -defined as an instance of organized violence with at least one fatalitycomes with date, geographical location, and identifiers that allow the dataset to be linked to and merged with other UCDP datasets. The first version of the dataset covers events of fatal violence on the African continent between 1989 and 2010. This article, firstly, introduces the rationale for the new dataset, and explains the basic coding procedures as well as the quality controls. Secondly, we discuss some of the data's potential weaknesses in representing the universe of organized violence, as well as some potential biases induced by the operationalizations. Thirdly, we provide an example of how the data can be used, by illustrating the association between cities and organized violence, taking population density into account. The UCDP GED is a useful resource for conflict analyses below the state and country-year levels, and can provide us with new insights into the geographical determinants and temporal sequencing of warfare and violence.

This article extends the Uppsala Conflict Data Program (UCDP) by presenting new global data on non-state conflict, or armed conflict between two groups, neither of which is the state. The dataset includes conflicts between rebel groups and other organized militias, and thus serves as a complement to existing datasets on armed conflict which have either ignored this kind of violence or aggregated it into civil war. The dataset also includes cases of fighting between supporters of different political parties as well as cases of communal conflict, that is, conflict between two social groups, usually identified along ethnic or religious lines. This thus extends UCDP's conflict data collection to facilitate the study of topics like rebel fractionalization, paramilitary involvement in conflict violence, and communal or ethnic conflict. In the article, we present a background to the data collection and provide descriptive statistics for the period 1989-2008 and then illustrate how the data can be used with the case of Somalia. These data move beyond state-centric conceptions of collective violence to facilitate research into the causes and consequences of group violence which occurs without state participation.

Studying an International Security Assistance Force contingent on tour in Afghanistan, the aim of the present study was to test assertions of the relative stability of personal values in a challenging environment. Three hundred twenty Swedish soldiers answered questionnaires on their values before and after a 6-month tour of Afghanistan. Value change and stability were studied via mean-level change, rank-order stability, and individual-level change methods. Regression analysis was used to study the impact of combat exposure and personality traits on change. The analysis concluded that even when experiencing such a different social context as a military mission to Afghanistan, the soldiers' values remained stable. Some minor changes occurred, in a pattern similar to a regression toward the mean. It was also shown that combat exposure--to a minor extent--predicted changes in values, whereas Big Five scores yielded stronger effects. The present findings suggest that the assertion of the stability of values is a well-founded proposition, even after radical changes in environment. However, the findings on the effects of combat exposure point to the possibility of severe life events having the power to exert change in values. Personality traits were, however, more important factors in the present context.
