Spreading a Patient-Centered Medical Home Redesign
Journal of Ambulatory Care Management, 2012Health care leaders and policymakers are turning to the patient-centered medical home (PCMH) model to contain costs, improve the quality of care, and create a more positive primary care work environment. We describe how Group Health, an integrated delivery system, developed and implemented a PCMH intervention that included standardized structural and ...

Hydrothermal mineralization at seafloor spreading centers
Earth-Science Reviews, 1984The recent recognition that metallic mineral deposits are concentrated by hydrothermal processes at seafloor spreading centers constitutes a scientific breakthrough that opens active sites at seafloor spreading centers as natural laboratories to investigate ore-forming processes of such economically useful deposits as massive sulfides in volcanogenic ...

Extensional transform zones and oblique spreading centers
Journal of Geophysical Research: Solid Earth, 1994Extensional transform zones (ETZs) are plate boundary segments of order 100 km long that strike at angles between 15° and 45° to the extension direction. They are characterized by neovolcanic/tectonic zones comprising overlapping en echelon volcanic systems and/or faults that trend 30°–75° to the extension direction, sometimes accompanied by a Riedel ...

Dynamics of a passive spreading center
Journal of Geophysical Research, 1976At a passive spreading center the motion of the fluid rising in the conduit between diverging lithosphere plates is generated by the motion and weight of the plates. Combined gravity and viscous forces exerted by the rising material on the overhanging conduit walls deform the adjacent lithosphere to produce sea floor topography.

Reversal transition widths and fast-spreading centers
Earth and Planetary Science Letters, 1977It is generally assumed by geomagnetists that spreading centers with the fastest separation rates should ultimately yield the most information concerning short-period behavior of the paleomagnetic field. We present results here that may indicate otherwise.

Spreading center dynamics and melt migration
Reviews of Geophysics, 1995Melting of upwelling mantle beneath spreading centers generates the basaltic crust that covers a large fraction of the Earth's surface. Crustal emplacement of mantle melt and faulting associated with lithosphere extension in a narrow, few kilometer wide region along the axis of spreading centers largely defines the structural and morphological fabric ...

Comparison Between Galapagos and Gorda Spreading Centers
Offshore Technology Conference, 1981Abstract The Gorda Ridge is an active slow rate (5.6 centimeters per year) spreading ridge located between 160 and 330 kilometers off the coasts of Northern California and Oregon. A prominent axial rift valley runs along the crest of the Gorda Ridge between the northern termination of the ridge at the Mendocino ...

Possible spreading centers in the Japan sea
Marine Geophysical Researches, 1975The magnetic anomaly profiles across the Japan and the Yamato Basins are analyzed to find possible spreading centers. Magnetic anomalies are first transformed and then the correlation coefficient of symmetry of the pattern of profile is computed along each profile.

High-magnetization zones near spreading center discontinuities
Earth and Planetary Science Letters, 1991Abstract Three-dimensional inversions of the magnetic field reveal the presence of zones of high magnetization over the propagating limb of large spreading center discontinuities. The presence of high-magnetization zones is confirmed by rock magnetic measurements where available. Magnetization highs are associated with basalts which tend to have high
