Changes in the prevalence of chronic disability in the United States black and nonblack population above age 65 from 1982 to 1999

Survey evidence through the early 1990s generally suggests a reduction in disability in the elderly population of the United States. Because the evidence is not fully consistent, several authors have speculated about whether disability declines will continue. This paper reports results from the 1999 National Long-Term Care Survey on disability trends from 1982 through 1999. It is found that disability continued to decline in the 1994 to 1999 period, and that the decline was greater in the 1990s than in the 1980s. The disability decline from 1982 to 1989 was 0.26% per year, from 1989 to 1994 it was 0.38% per year, and from 1994 to 1999 it was 0.56% per year. In addition, disability declined by a greater percentage for blacks than for nonblacks over the 1989 to 1999 period.

Trends and patterns in research and development expenditures in the United States

This paper is a review of recent trends in United States expenditures on research and development (R&D). Real expenditures by both the government and the private sector increased rapidly between the mid-1970s and the mid-1980s, and have since leveled off. This is true of both overall expenditures and expenditures on basic research, as well as funding of academic research. Preliminary estimates indicate that about $170 billion was spent on R&D in the United States in 1995, with ≈60% of that funding coming from the private sector and about 35% from the federal government. In comparison to other countries, we have historically spent more on R&D relative to our economy than other advanced economies, but this advantage appears to be disappearing. If defense-related R&D is excluded, our expenditures relative to the size of the economy are considerably smaller than those of other similar economies.

Long-range transport of mineral dust in the global atmosphere: Impact of African dust on the environment of the southeastern United States

Soil dust is a major constituent of airborne particles in the global atmosphere. Dust plumes frequently cover huge areas of the earth; they are one of the most prominent and commonly visible features in satellite imagery. Dust is believed to play a role in many biogeochemical processes, but the importance of dust in these processes is not well understood because of the dearth of information about the global distribution of dust and its physical, chemical, and mineralogical properties. This paper describes some features of the large-scale distribution of dust and identifies some of the geological characteristics of important source areas. The transport of dust from North Africa is presented as an example of possible long-range dust effects, and the impact of African dust on environmental processes in the western North Atlantic and the southeastern United States is assessed. Dust transported over long distances usually has a mass median diameter <10 μm. Small wind-borne soil particles show signs of extensive weathering; consequently, the physical and chemical properties of the particles will greatly depend on the weathering history in the source region and on the subsequent modifications that occur during transit in the atmosphere (typically a period of a week or more). To fully understand the role of dust in the environment and in human health, mineralogists will have to work closely with scientists in other disciplines to characterize the properties of mineral particles as an ensemble and as individual particles especially with regard to surface characteristics.

Consequences of the Past: China's Rise to Superpower Status and its Impact on the United States

This paper investigates the impact of how the Chinese government will react to the West if China regains its superpower status. Using traditional research methods, this paper traced the cultural misunderstandings that initiated the confrontation with the West and the resulting humiliation China suffered for nearly 175 years by the Western powers. The findings of this paper show that China bitterly resents the treatment suffered during the Colonial period. Although certain factions in China wish to punish the West, this paper argues that the interconnected nature of the world's economy will force China to temper its feelings and build bridges with the West as it attains superpower status.

The European Union and the United States, before the election: a much deeper mutual understanding. Jean Monnet/Robert Schuman Paper Series Vol. 12 Special, October 2012

From the Introduction. Governor Romney’s statement that President Obama was trying to convert the United States into a European state actually served to point out the need for a much deeper understanding of both entities to make considerable progress in the future. The need for a close alliance is taken for granted. However, the link is riddled with confusion and stereotypes. This relationship is considered a normal fact forged by mutual historical legacies. Hence the frequent signs of awkward behaviour and misunderstandings under the cover of the notion that potential damage will be corrected by the force of the special relationship. If conflicts are detected, both parties are said to be condemned to agree. If a lack of knowledge is detected, it will be modified by accessible means. Mechanisms for an understanding and cooperation are within reach. Therefore, an effective relationship is not utopian. However, there are areas in which much work is needed to strengthen the alliance and correct its shortcomings. There is a need, not only for agreements in economic and political issues, but also for a deeper understanding of the essence of both entities.
