The United States operates the world’s largest refugee resettlement program. However, there is almost no systematic evidence on whether refugees successfully integrate into American society over the long run. We address this gap by drawing on linked administrative data to directly measure a long-term integration outcome: naturalization rates. Assessing the full population of refugees resettled between 2000 and 2010, we find that refugees naturalize at high rates: 66% achieved citizenship by 2015. This rate is substantially higher than among other immigrants who became eligible for citizenship during the same period. We also find significant heterogeneity in naturalization rates. Consistent with the literature on immigration more generally, sociodemographic characteristics condition the likelihood of naturalization. Women, refugees with longer residency, and those with higher education levels are more likely to obtain citizenship. National origins also matter. While refugees from Iran, Iraq, and Somalia naturalize at higher rates, those from Burma, Ukraine, Vietnam, and Liberia naturalize at lower rates. We also find naturalization success is significantly shaped by the initial resettlement location. Placing refugees in areas that are urban, have lower rates of unemployment, and have a larger share of conationals increases the likelihood of acquiring citizenship. These findings suggest pathways to promote refugee integration by targeting interventions and by optimizing the geographic placement of refugees.

When did European modes of political thought diverge from those that existed in other world regions? We compare Muslim and Christian political advice texts from the medieval period using automated text analysis to identify four major and 60 granular themes common to Muslim and Christian polities, and examine how emphasis on these topics evolves over time. For Muslim texts, we identify an inflection point in political discourse between the eleventh to thirteenth centuries, a juncture that historians suggest is an ideational watershed brought about by the Turkic and Mongol invaders. For Christian texts, we identify a decline in the relevance of religious appeals from the Middle Ages to the Renaissance. Our findings also suggest that Machiavelli’s Prince was less a turn away from religious discourse on statecraft than the culmination of centuries-long developments in European advice literature.

Targeted killing by drones is a systemic driven instrumental practice that overrides societal non-instrumental practices that are essential for international society. Doing so, targeted killing by drones is not simply another form of inflicting violence by technical means to political opponents. It also inflicts the agents applying this practice, tempting them to frame it as a permissible measure to preserve international society. The reliance on drones for targeted killing is a pursuit of non-societal practices that seek individual and retributive justice and anticipatory and preventive self-defence by means of force relying on technological advantage. Eventually, this practice permits military tactics to steer political strategy, mitigating standards and practices agreed on in international society’s norms, rules of conduct, and institutions.

Soon after Raphael Lemkin coined the term “genocide” in Axis Rule in Occupied Europe in 1944, he began working on a world history of genocide to popularize his neologism. Correspondence with funding organizations and publishers shows that he was soliciting interest in a book on the subject as early as 1947 and that he had produced substantial draft chapters by the following year. Before his death in 1959, he had almost completed the book on genocide in world history but, in marked contrast to the present, publishers were uninterested in the project, which was neither completed nor published. Both Lemkin and his approach were forgotten until the 1980s, when a small group of social scientists founded a marginal field called comparative genocide studies.

We study the short and long-term spillover effects of a pay reform that substantially increased the returns to schooling in Israeli kibbutzim. This pay reform, which induced kibbutz students to improve their academic achievements during high school, spilled over to non-kibbutz members who attended schools with these kibbutz students. In the short run, peers of kibbutz students improved their high school outcomes and shifted to courses with higher financial returns. In the medium and long run, peers completed more years of postsecondary schooling and increased their earnings. We discuss three main spillover channels: diversion of teachers’ instruction time towards peers, peer effects from improved schooling performance of kibbutz students, and the transmission of information about the returns to schooling. While each of these channels likely contributed to improving the outcomes of peers, we provide suggestive evidence that the estimates are more consistent with the effects operating mainly through transmission of information.

Maritime Southeast Asia, the area circumscribed by the Malaysian peninsula, the Indonesian archipelago and the Philippines, is vital to US strategic concerns for two primary reasons. First, this region includes the South China Sea where American and Chinese ambitions may be heading toward direct conflict as China continues to press forward with its agenda of extending its reach. Second, the region is of crucial importance for world shipping routes that are vulnerable to potential disruption due to the geography of the narrow passages at the Sunda Strait (between the Indonesian islands of Java and Sumatra) and the Strait of Malacca (between Sumatra and the Malaysian peninsula). It is important that these ocean ways remain open to unencumbered passage and free trade, subject to the rule of law, and it is crucial that the US, as guarantor of the free seas, retain its capacity to project its power in the region and avoid being shut out by a competing power.

The article introduces the All Minorities at Risk (AMAR) data, a sample of socially recognized and salient ethnic groups. Fully coded for the forty core Minorities at Risk variables, this AMAR sample provides researchers with data for empirical analysis free from the selection issues known in the study of ethnic politics to date. We describe the distinct selection issues motivating the coding of the data with an emphasis on underexplored selection issues arising with truncation of ethnic group data, especially when moving between levels of data. We then describe our sampling technique and the resulting coded data. Next, we suggest some directions for the future study of ethnicity and conflict using our bias-corrected data. Our preliminary correlations suggest selection bias may have distorted our understanding about both group and country correlates of ethnic violence.
