The call for family and medical leave reform in the United States was largely the result of sweeping demographic shifts that occurred in the workforce after the 1950s, coupled with an ever-increasing life expectancy and changing social norms concerning the role of women as caretakers. By the early 1990s, the number of women in the workforce had nearly tripled from 1950. During that same period, life expectancy increased by six years for males and seven for females. Meanwhile, the first wave of the Depression-era generation began to reach the age of retirement. In short, the parents of American workers were living longer and retiring in greater numbers while more women, who were more likely to be informal caregivers, decided to join the workforce. As a result, many families with ill or elder parents began to turn to institutional long-term care.

Recent developments in the health care industry have precipitated a new wave of interest in expanding the scope of practice for nursing. This is because the Patient Protection and Affordable Care Act, broadly designed to increase access to health insurance, will inevitably result in increased demand for primary care providers. And with compensation for primary care physicians already lagging far behind that of specialists, the role of nurse practitioners is once again receiving increased attention as a viable means by which to ease the pressure for access to health care.But the economics of this trade-off are controversial. On one hand, it sets primary care physicians at odds with specialists; namely, if the ultimate goal is to “bend the cost curve downward,” should specialist compensation be reduced in order to increase spending on primary care?

© 2015 Published by John Wiley & Sons Ltd.Soil transplant serves as a proxy to simulate climate changes. Recently, we have shown that southward transplant of black soil and northward transplant of red soil altered soil microbial communities and biogeochemical variables. However, fundamental differences in soil types have prevented direct comparison between southward and northward transplants. To tackle it, herein we report an analysis of microbial communities of Cambisol soil in an agriculture field after 4 years of adaptation to southward and northward soil transplants over large transects. Analysis of bare fallow soils revealed concurrent increase in microbial functional diversity and coarse-scale taxonomic diversity at both transplanted sites, as detected by GeoChip 3.0 and DGGE, respectively. Furthermore, a correlation between microbial functional diversity and taxonomic diversity was detected, which was masked in maize cropped soils. Mean annual temperature, soil moisture, and nitrate showed strong correlations with microbial communities. In addition, abundances of ammonium-oxidizing genes and denitrification genes were correlated with nitrification capacity and NO3--N contents, suggesting that microbial responses to soil transplant could alter microbe-mediated biogeochemical cycle at the ecosystem level. This study proved that microbial responses to southward and northward soil transplants were asymmetric. Microbial responses at the community level to soil transplant can result in altered ecosystem-level biogeochemical cycle.
