The detection of psychiatric illness by questionnaire

www.mobilehealthmap.org 617‐442‐3200 New research shows that mobile health clinics improve health outcomes for hard to reach populations in cost‐effective and culturally competent ways . A Harvard Medical School study determined that for every dollar invested in a mobile health clinic, the US healthcare system saves $30 on average. Mobile health clinics, which offer a range of services from preventive screenings to asthma treatment, leverage their mobility to treat people in the convenience of their own communities. For example, a mobile health clinic in Baltimore, MD, has documented savings of $3,500 per child seen due to reduced asthma‐related hospitalizations. The estimated 2,000 mobile health clinics across the country are providing similarly cost‐effective access to healthcare for a wide range of populations. Many successful mobile health clinics cite their ability to foster trusting relationships. Qualitative research in such mobile health clinics has found that patients value the informal, familiar environment in a convenient location, with staff who “are easy to talk to,” and that the staff’s “marriage of professional and personal discourses” provides patients the space to disclose information themselves. A communications academic argued that mobile health clinics’ unique use of space is important in facilitating these relationships. Mobile health clinics park in the heart of the community in familiar spaces, like shopping centers or bus stations, which lend themselves to the local community atmosphere.

Four specimens Me{sub x}Ni{sub 1{minus}x}O - 14.2 mol% TiO{sub 2} (Me=Mg,Co and x=0.1 or 0.2) were prepared by cold pressing and firing. After heating and quenching, slices were examined in a TEM and x-ray spectrometry carried out. Dark-field images were recorded near the [001]-pole of the two cubic phases with spinel (220) reflection. The spinel-structured phase appears bright, the periclase-structured phase dark. In the 20% CoO doped specimen, the spinel and periclase phases form a continuously interpenetrating network (scale 40 nm); examination of the site distributions with ALCHEMI indicates that the Ti cations occupy mostly the octahedral site (tetrahedral site in undoped material). The spinel MgNiTiO{sub 4} is unstable. The arrangements of the some of the faceted particles in groups suggest that a large periclase-structured particle may have subdivided.

In this paper we study a novel class of parabolic geometries which we call parabolic geometries of Monge type. These parabolic geometries are defined by special gradings of simple Lie algebras, namely, gradings with the property that their -1 component contains a nonzero co-dimension 1 abelian subspace whose bracket with its complement is non-degenerate. We completely classify the simple Lie algebras with such gradings in terms of elementary properties of the defining set of simple roots. We then characterize those parabolic geometries of Monge type which are non-rigid in the sense that, apart from the flat models, they have nonzero harmonic curvatures in positive weights. Standard models of all non-rigid parabolic geometries of Monge type are then described by under-determined ODE systems. The full symmetry algebras for these under-determined ODE systems are explicitly calculated; surprisingly, these symmetries are all just prolonged point symmetries.

DifferentialGeometry is a Maple software package which symbolically performs fundamental operations of calculus on manifolds, differential geometry, tensor calculus, Lie algebras, Lie groups, transformation groups, jet spaces, and the variational calculus. These capabilities, combined with dramatic recent improvements in symbolic approaches to solving algebraic and differential equations, have allowed for development of powerful new tools for solving research problems in gravitation and field theory. The purpose of this paper is to describe some of these new tools and present some advanced applications involving: Killing vector fields and isometry groups, Killing tensors and other tensorial invariants, algebraic classification of curvature, and symmetry reduction of field equations.

Synopsis Let W be a differential system on a manifold M. The infinitesimal symmetry algebra of W is the set of all vectors fields X on M such that L X W 3 W. In this worksheet we present an example, due to E. Cartan [2] p. 418 (see also K. Yamaguchi [3] p. 482), of a rank 7 Pfaffian system on a 15-dimensional manifold whose infinitesimal symmetry algebra is the split real form of the exceptional Lie algebra f 4 . The analysis of these symmetries presents a number of computational challenges which we address in Sections 1 and 2.
