The consequences of nationalism: A scholarly exchange

The main thrust of the scholarship on nationalism has so far been concerned with its origins. But nationalism also has effects. Whether it underpins the nation-building efforts of states, is mobilised by counter-state forces or is used in everyday life, nationalism might implicate a wide range of substantive outcomes, including political regimes, public goods provision, citizenship and immigration laws, and different patterns of conflict. Yet—with a few notable exceptions—the consequences of nationalism have received significantly less scholarly attention. In response, the aim of this Exchange is to create a new dialogue between different strands of scholarship around what we know and do not know about the consequences of nationalism. We organise this Exchange around the following questions: (1) What is nationalism? (2) How can we measure nationalism? (3) What are the consequences of nationalism? (4) What are new research frontiers?     

Exchange on the quantitative measurement of ethnic and national identity*

In recent decades, there has been a noticeable increase in the use of quantitative techniques in the study of ethnicity and nationalism, without, however, a sufficient amount of reflection on how these techniques have contributed to our understanding of ethnic and national identities. As such, in this exchange three sets of authors answer questions about the degree to which it is possible to use quantitative data to measure ethnic and national identities, which types of methods are most suitable in measuring these identities and what the major research findings of this quantitative research are that were not possible using qualitative approaches.     

Weighted Spatial Adaptive Filtering: Monte Carlo Studies and Application to Illicit Drug Market Modeling

This paper introduces a pattern recognizer, similar to weighting schemes used in combining time series forecasts, for use in spatial adaptive filtering applied to estimating multivariate cross-sectional models. The pattern recognizer enhances the ability to automatically detect and estimate parameters with discontinuous or sharp gradient changes over geographic contexts. Results from Monte Carlo studies suggest that the weighted spatial adaptive filter is at least as accurate as the unweighted filter for cases having smoothly changing parameters, but superior for cases having discontinuous, step-jump parameters. A case study on illicit drug-market activities using census tract-level data from Pittsburgh, Pennsylvania, further illustrates the advantages of the weighted filter.     

“Frequent Deaths”: The Colonial Development of Concentration Camps Reconsidered, 1868–1974

This article sheds new light on the development of concentration camps in colonial warfare in the longue durée from 1868 to 1974. Introducing different examples of forced removal and deportation in the Spanish and Portuguese empires, the analysis emphasizes their interrelation, highlighting possible transfers of knowledge that have been neglected in comparative discussions. Specifically, the article reassesses the Cuban experience of concentrating civilians in times of war (1868–98); it critically evaluates Spain’s forgotten concentration camps on the Canary Islands, which emerged during the Ifni-Sahara war of 1957–58; and it focuses on both the theory of revolutionary warfare and the practice of so-called strategic resettlement in the long and protracted Portuguese colonial wars in Africa (1961–74). In particular, the camps on the Canary Islands suggest the need for an analytical distinction between the function of forced removals in counter-guerrilla warfare and administrative internment; they are related but essentially different policies. Based on hitherto ignored archival material, this empirically supported analysis challenges common assumptions about the “origins” of camps, and questions traditional temporal boundaries in the development of (anti-)guerrilla warfare.     

Food for all: An agent-based model to explore the emergence and implications of cooperation for food storage

Abstract

A consistent access to food is paramount for humans at individual and group level. Besides providing the basic nutritional needs, access to food defines social structures and has stimulated innovation in food procurement, processing and storage. We focus on the social aspects of food storage, namely the role of cooperation for the emergence and maintenance of common stocks. Cooperative food stocks are examined here as a type of common-pool resource, where appropriators must cooperate to avoid shortage (i.e. the tragedy of commons). ‘Food for all’ is an agent-based model in which agents face the social dilemma of whether or not to store in a cooperative stock, adapting their strategies through a simple reinforcement learning mechanism. The model provides insights on the evolution of cooperation in terms of storage efficiency and considering the presence of social norms that regulate reciprocity. For cooperative food storage to emerge and be maintained, a significant dependency on the stored food and some degree of external pressure are needed. In fact, cooperative food storage emerges as the best performing strategy when facing environmental stress. Likewise, an intermediate control over reciprocity favours cooperation for food storage, suggesting that concepts of closed reciprocity are precursors to cooperative stocks, while excess control over reciprocity is detrimental for such institution.     

Final Paleolithic and Mesolithic Research in Reunified Germany

During the past decade research into the German Final Paleolithic and Mesolithic has experienced an important revival. One clear sign of this renewed interest in the periods are the annual meetings of the Arbeitsgruppe Mesolithikum (Mesolithic Working Group) which have taken place every spring since 1992. At these meetings, which take place at changing venues, topical themes of Final Paleolithic and Mesolithic interest are presented by informal lectures and it is also possible to study regional collections (artifacts, raw materials) at first hand. Numerous contributions were subsequently published together in one volume (Conard and Kind (1998) Aktuelle Forschungen zum Mesolithikum/Current Mesolithic Research, Mo Vince, Tübingen). The present paper intends to complement that collection of papers with a synthesis of developments and perspectives and to present recent research highlights in the German Final Paleolithic and Mesolithic, together with a comprehensive bibliography, to a wider international audience.
