    Abstract The purpose of this study was to explore registered nurses’ understanding and practice of “independent double-checks” prior to administration of high-alert medications. The study used a qualitative descriptive design for data collection and data analysis. It included thirteen participants from a hospital located in southern New Hampshire. Results of the study revealed a core theme of navigating independent double checks (IDC) for safer care. Two major themes stemming from the core theme were also uncovered. Navigating IDC through knowing and navigating IDC through nurse partnership both focused on the perception and practice on IDC prior to administration of high alert medications. IDC was accepted and promoted as best practice, but the definition and process is still unclear. Having a universal definition will assist in clarity of the process and in turn, promote ensuring safe administration of high alert medications to patients.

    Jumping bristletail (Insecta: Apterygota: Microcoryphia) records in the southeastern United States

    Get PDF
    Few records of Microcoryphia exist for the southeastern United States, with named species being reported only from Arkansas, Tennessee, and the mid-Atlantic states, and with an unnamed species being reported from Georgia. Records are here provided from 291 specimens housed in the Mississippi Entomological Museum, including ten new species-level state records. This is also the first published report of the order Microcoryphia from Alabama and Mississippi. Species include the machilids Pedetontoides atlanticus Mendes in Alabama, Arkansas, Georgia, Mississippi, and North Carolina; Pedetontus cf. atlanticus in Kentucky; Pedetontus (Verhoeffilis) gershneri Allen in Arkansas; and Pedetontus (Pedetontus) saltator Wygodzinsky and Schmidt in Mississippi and North Carolina; and the meinertellid Machiloides banksi (Silvestri) in Alabama, Arkansas, Mississippi, and North Carolina

    Lsdiff M and the Einstein Equations

    Full text link
    We give a formulation of the vacuum Einstein equations in terms of a set of volume-preserving vector fields on a four-manifold M{\cal M}. These vectors satisfy a set of equations which are a generalisation of the Yang-Mills equations for a constant connection on flat spacetime.Comment: 5 pages, no figures, Latex, uses amsfonts, amssym.def and amssym.tex. Note added on more direct connection with Yang-Mills equation

    The ADHM construction and non-local symmetries of the self-dual Yang-Mills equations

    Get PDF
    We consider the action on instanton moduli spaces of the non-local symmetries of the self-dual Yang-Mills equations on R4\mathbb{R}^4 discovered by Chau and coauthors. Beginning with the ADHM construction, we show that a sub-algebra of the symmetry algebra generates the tangent space to the instanton moduli space at each point. We explicitly find the subgroup of the symmetry group that preserves the one-instanton moduli space. This action simply corresponds to a scaling of the moduli space.Comment: AMSLatex, 19 pages, no figures. Some discussions clarified, and citations made more accurate. I am grateful to the referee for detailed comments. Version to appear in Communications in Mathematical Physic

    A Spinorial Hamiltonian Approach to Gravity

    Full text link
    We give a spinorial set of Hamiltonian variables for General Relativity in any dimension greater than 2. This approach involves a study of the algebraic properties of spinors in higher dimension, and of the elimination of second-class constraints from the Hamiltonian theory. In four dimensions, when restricted to the positive spin-bundle, these variables reduce to the standard Ashtekar variables. In higher dimensions, the theory can either be reduced to a spinorial version of the ADM formalism, or can be left in a more general form which seems useful for the investigation of some spinorial problems such as Riemannian manifolds with reduced holonomy group. In dimensions 0(mod4)0 \pmod 4, the theory may be recast solely in terms of structures on the positive spin-bundle V+\mathbb{V}^+, but such a reduction does not seem possible in dimensions 2(mod4)2 \pmod 4, due to algebraic properties of spinors in these dimensions.Comment: 20 pages, Latex 2e.
