In this essay the communication practices of labor migrants and their evolution from nineteenth-century print media to late twentiethcentury electronic media provide the frame for a discussion of the limitations of national approaches to collection and interpretation. Multiple languages and knowledge of cultures of origin are required, cooperative library and research projects are necessary. On...

By most measures, the United States is the most unequal of the world's advanced capitalist economies, and inequality has increased substantially over the past 30 years. This article documents trends in the inequality of three key economic distributions--hourly earnings, annual incomes, and net wealth--and relates these developments to changes in economic and social policy over the past three de...

The western Pacific subtropical high (WPSH) is closely related to Asian climate. Previous examination of changes in the WPSH found a westward extension since the late 1970s, which has contributed to the interdecadal transition of East Asian climate. The reason for the westward extension is unknown, however. The present study suggests that this significant change of WPSH is partly due to the atm...

Prophylactic treatment in severe hemophilia is very effective but is limited by cost issues. The implementation of 2 different prophylactic regimens in The Netherlands and Sweden since the 1970s may be considered a natural experiment. We compared the costs and outcomes of Dutch intermediate- and Swedish high-dose prophylactic regimens for patients with severe hemophilia (factor VIII/IX < 1 IU/d...

INTRODUCTION Producing estimates of infant (under age 1 y), child (age 1-4 y), and under-five (under age 5 y) mortality rates disaggregated by sex is complicated by problems with data quality and availability. Interpretation of sex differences requires nuanced analysis: girls have a biological advantage against many causes of death that may be eroded if they are disadvantaged in access to resou...

Improving the understanding of cropland change and its driving factors is a current focus for policy decision-makers in China. The datasets of cropland and cropland changes from the 1970s to the 2000s were used to explore whether climate change has produced spatiotemporal changes to cropland in northern China since the 1970s. Two representative indicators of heat and water resources, which are ...

Since the 1970s almost all OECD countries have published projections or forecasts of future energy consumption. By now, three decades later, the actual values of energy consumption are available for the same number of countries and thus a considerable amount of empirical data is available concerning formal hypothesis testing, e.g. whether there have been improvements in the forecasting accuracy...
