Objective Examine the extent to which physician organization participation in an accountable care organization ( ACO ) and electronic health record ( EHR ) functionality are associated with greater adoption of care transition management ( CTM ) processes. Data Sources/Study Setting A total of 1,398 physician organizations from the third National Study of Physician Organization survey ( NSPO 3), a nationally representative sample of medical practices in the United States (January 2012—May 2013). Study Design We used data from the third National Study of Physician Organization survey ( NSPO 3) to assess medical practice characteristics, including CTM processes, ACO participation, EHR functionality, practice type, organization size, ownership, public reporting, and pay‐for‐performance participation. Data Collection/Extraction Methods Multivariate linear regression models estimated the extent to which ACO participation and EHR functionality were associated with greater CTM capabilities, controlling for practice size, ownership, public reporting, and pay‐for‐performance participation. Principal Findings Approximately half (52.4 percent) of medical practices had a formal program for managing care transitions in place. In adjusted analyses, ACO participation ( p < .001) and EHR functionality ( p < .001) were independently associated with greater use of CTM processes among medical practices. Conclusions The growth of ACO s and similar provider risk‐bearing arrangements across the country may improve the management of care transitions by physician organizations.
An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space group, experimental conditions and quality measures.
The quality of algae as food for larval Pacific treefrogs, Hyla regilla, varies among algal taxa. Tadpole diets were manipulated in enclosures in the South Fork Eel River, northern California. Enclosed tadpoles were fed ad libitum one of the dominant filamentous green algae (Cladophora, Zygnema, Mougeotia, or Oedogonium), the dominant cyanobacterium in the habitat (Nostoc), flocculent detritus, or a commercial reptile/amphibian food. Tadpoles in a control treatment were not fed but had access to seston which deposited in all enclosures. Diet treatment significantly affected weekly growth rates, as well as time to and weight at metamorphosis. Tadpoles grew most rapidly on filamentous green algae with diatom epiphytes and on the commercial food. Tadpoles fed epiphytized Cladophora metamorphosed 27.1% (11.7 days) sooner and weighed 38.9% (70 mg) more than tadpoles fed Cladophora cleaned of diatoms. In comparison to tadpoles fed Mougeotia, which does not support epiphytes, tadpoles fed epiphytized Cladophora metamorphosed 37.4% (19.7 days) sooner and weighed 31.6% (50 g) more. Tadpoles with the lowest growth rates were those filtering deposited seston or flocculent detritus. Observed changes in life-history traits with diet are assessed in relation to models which predict the optimal timing of metamorphosis.
Appreciation of the Keynesian synthesis was enhanced by the events of the last decade. The global financial crisis highlighted the fragility of financial markets and the capriciousness of animal spirits. The depth of the downturn pointed to the value of not just automatic stabilizers but also discretionary fiscal policy as tools of macroeconomic management. Keynesian models and not their New Classical challengers provided the practical analytical framework for policy design. Models of the anti-Keynesian effects of fiscal consolidation received little support from actual consolidation experience. The secular-stagnation debate that followed the crisis lent legitimacy to the view that policy-makers with fiscal space were wise to use it.

— Cyclic fatigue‐crack growth and resistance‐curve behavior have been studied in a fine‐grained (∼ 1 μm), high‐purity alumina. Specific emphasis is given to the mechanisms associated with crack growth that are controlled by the maximum ( K max ) and the alternating (Δ K ), stress intensities and to the role of crack‐face interference (crack closure), which is known to be an important crack‐tip shielding mechanism in metal fatigue. Significant levels of subcritical crack growth were detected above a threshold stress intensity of ∼60% of the fracture toughness ( K c ) in the alumina, with growth rates displaying a far larger dependence on K max compared to Δ K. The role of crack closure was examined using constant‐ K max experiments, where the minimum stress intensity ( K min ) was maintained either above or below the stress intensity for crack closure ( K cl ). Where K min < K cl , growth rates were found to exhibit a lower dependence on Δ K , which was rationalized in terms of the frictional wear model for crack growth in grain‐bridging ceramics. It is concluded that crack closure, as conventionally defined, has little relevance as a crack‐tip shielding mechanism during fatigue‐crack growth in grain‐bridging ceramics, due to the low dependence of growth rates on Δ K compared to K max .
