Abstract. We propose a vector alternative to the typical raster based population modeling framework. When compared with rasters, vectors are more precise, have the ability to hold more information, and are more conducive to areal constructs such as building and parcel outlines. While rasters have traditionally provided computational efficiency, much of this efficiency is reduced at finer resolutions and computational resources are more plentiful today. Herein we describe the approach and implementation methodology. We also describe the output data stack for the United States and provide examples and applications.

A growing body of academic research and policy initiatives has addressed the global race for talent against the backdrop of the unprecedented scope and pace of skilled international migration. In this article, we coin the term “intellectual migration” as an analytical framework for international migration to explore how the experiences of students and skilled migrants to the United States from Brazil, Russia, India, and China (the bric countries) complicate notions of brain circulation. This framework not only brings together students and skilled migrants but also takes into account the complex relationship between these migrants’ career aspirations and their connections to their (extended) families, their racialization in the United States, and economic and geopolitical changes in their home countries.

In 1988, the United States recorded a deficit of about $135 billion on the current account of its balance of payments with the rest of the world. This paper presents an analytical framework for thinking about the current account deficit, explores causes of the current account deficit, and discusses the United States as a debtor nation and the issue of sustainability.

There are few remaining longleaf pine ( Pinus palustris Mill.) ecosystems left in the southeastern coastal plain of the United States. Restoration and maintenance of these remaining habitats requires an understanding of ecosystem processes at multiple scales. The focus of this study was to develop and evaluate a modeling framework for analyzing longleaf pine dynamics at the spatially explicit landscape scale and at the spatially implicit population scale. The landscape disturbance and succession (LANDIS) model was used to simulate landscape fire dynamics in a managed forest in north-central Florida. We constructed a density-dependent longleaf pine population matrix model using data from a variety of studies across the southeastern United States to extend an existing model. Sensitivity analyses showed that the most sensitive parameters were those from the original pine model, which was based on extensive observations of individual trees. A hybrid approach integrated the two models: the fire frequencies output from the LANDIS model were input to the matrix model for specific longleaf pine populations. These simulations indicated that small isolated longleaf pine populations are more vulnerable to fire suppression and that landscape connectivity is a critical concern. A frequent prescribed fire regime is nonetheless necessary to maintain even large longleaf pine sandhill communities that have better landscape connectivity.

The Business Cycle

Have postwar stabilization policies reduced economic fluctuations compared to earlier periods? Using output data for Canada, Sweden and the United States for the period 1929-2005 and three different de-trending procedures, we found that postwar economic policies have been successful in reducing business cycle volatility. We also found that fluctuations in real output have been significantly dampened during the post-Bretton Woods era compared to earlier periods.

Foreign Scholar

This chapter details events following Ernst Kantorowicz's arrival in America. His first few months were difficult. His future was uncertain, he was short of money, and he did not like New York City. His first lecture in the United States was as a guest at a regularly scheduled class at Barnard College. He later toured New England, speaking at Harvard, Smith College, and Yale. His Harvard talk, entitled “The Idea of Permanency and Progress in the Thirteenth Century” and was a milestone in his historiographical progress. Although it was a revised version of the introductory section of his aborted book on the German Interregnum, the revisions introduced a new analytical concept and adumbrated a new analytical framework. The new concept was the significance of the thirteenth-century scholastic term aevum.

Community Attachments

This article examines how religion, including new religious movements as well as older options in new contexts, combines with ethnic and community attachments in shaping the identity of Guatemalan economic migrants in southern California. While the literature on transnationalism tends to view religion and ethnicity as different though sometimes overlapping means by which migrants seek incorporation into new social and political contexts, the ethnographic evidence presented here suggests more complicated dynamics. These are reflected in the experiences of three migrants from a single indigenous community in Guatemala, each with different backgrounds of faith and ethnic identity: a nominal Catholic in his early 20s who is sympathetic to Mesoamerican shamanism though ambivalent about Maya ethnic identity; a middle-aged Pentecostal Christian who is ambivalent about religious practice and belief in the United States and rejects the Maya ethnic label; and a convert to Mormonism in his 30s who has attenuated his ties to his home community while adopting a broader Maya ethnic identity. To interpret these experiences, I develop an analytical framework which draws upon some of Thomas Csordas’ ideas about religion in globalization but stresses a renewed attention to community as a persistent, if ambivalent and perhaps inherently conflictive, site for identity formation, especially in the context of migration.

Victimization Research

While age is one of the most important correlates of an individual’s risk of violent victimization, research regarding the victimization of adolescents is relatively meager. Using two well-known national data sources and an analytical framework guided by lifestyle/routine activities theories, we describe the relationships between activity involvement and the risk of assault and robbery victimization among adolescents in the United States. Several findings relevant to victimization prevention emerge. First, we find that certain adolescent activities are related to risk of violence. Youth who engage in delinquent activities experience the highest risk of assault and robbery victimization. Second, we find very few conventional activities which protect adolescents from victimization net of background factors (e.g., gender, race, family structure) or offending levels. We discuss the implications of these findings for programs directed at reducing violent victimization among adolescents and for lifestyle/routine activities theories of victimization.

Drawing on the existing welfare state literature, this article offers a comparative analytical framework to account for the territorial dynamics of social policy in the United States and the People’s Republic of China, two countries that are most dissimilar in terms of political regime but that may exhibit similar territorial patterns of social policy fragmentation. A promising way to explore such patterns, we argue, is to analyze how changes in the architecture of major governing institutions affect the territorial dimension of social policy. In the United States, state governments and a territorially-organized federal legislature have increasingly accommodated national political parties. These two parties have turned the politics of social policy into a debate over the boundaries of national or state governance of social policy, resulting in multi-level governance frameworks. In the People’s Republic of China, the partisan dimension is absent, but strong economic pressures on the central bureaucracy have made devolution a functional imperative and have given local governments increasing leverage when bargaining with the center.

This introductory article provides European readers with a succinct review of the organisation and activity of trade unions in the US. It also provides an analytical framework within which some of the strategic options available to US trade unions in the new millennium may be analysed. Three options are addressed: ‘reform for competitive advantage', ‘associational unionism’ and an adversarial ‘social-movement strategy'.
