    Advocacy Coalition Framework Lens on Pressing Healthcare Issues

    Full text link
    In deciding how to interpret and understand public policy, many experts use theories and frameworks to justify their reasoning. One of the most common avenue of viewing policy involves the advocacy coalition framework based on its broad applicability. This popular framework consists of banding like-minded individuals together into a coalition to advance the narrative by creating acceptable policies for their group. These coalitions normally include a wide range of professional backgrounds from interest groups, elected officials, researchers in academia. These groups utilize special events to influence subfields consisting of actors who decide the solutions for policy problems. Subfields normally are made up of key players employed in government institutions and private industrial groups who willingly agree to work toward a compromise with the goal to create policy acceptable for both sides (Cairney 2014) These coalitions influence the subfield in different ways through capitalizing on their influential power or by ignoring the alliances and mergers of the groups. This paper shall explore how advocacy coalition framework works for three pressing issues facing the healthcare industry. These three policies focus on drug pricing, heath data privacy and opioid liability. This paper will explore the policy in depth, provide historical context and the major players while outlining how the specific proposals fit in the framework as well as identifying the framework’s limitations with the policy

    Evidence for the Strong Effect of Gas Removal on the Internal Dynamics of Young Stellar Clusters

    We present detailed luminosity profiles of the young massive clusters M82-F, NGC 1569-A, and NGC 1705-1 which show significant departures from equilibrium (King and EFF) profiles. We compare these profiles with those from N-body simulations of clusters which have undergone the rapid removal of a significant fraction of their mass due to gas expulsion. We show that the observations and simulations agree very well with each other suggesting that these young clusters are undergoing violent relaxation and are also losing a significant fraction of their stellar mass. That these clusters are not in equilibrium can explain the discrepant mass-to-light ratios observed in many young clusters with respect to simple stellar population models without resorting to non-standard initial stellar mass functions as claimed for M82-F and NGC 1705-1. We also discuss the effect of rapid gas removal on the complete disruption of a large fraction of young massive clusters (``infant mortality''). Finally we note that even bound clusters may lose >50% of their initial stellar mass due to rapid gas loss (``infant weight-loss'').Comment: 6 pages, 3 figures, MNRAS letters, accepte

    Finite dimensional irreducible representations of finite W-algebras associated to even multiplicity nilpotent orbits in classical Lie algebras

    Full text link
    We consider finite W-algebras U(g,e) associated to even multiplicity nilpotent elements in classical Lie algebras. We give a classification of finite dimensional irreducible U(g,e)-modules with integral central character in terms of the highest weight theory for finite W-algebras. As a corollary, we obtain a parametrization of primitive ideals of U(g) with associated variety the closure of the adjoint orbit of e and integral central character.Comment: 38 Pages; made some minor correction

    A robust method for measuring the Hubble parameter

    Get PDF
    We obtain a robust, non-parametric, estimate of the Hubble constant from galaxy linear diameters calibrated using HST Cepheid distances. Our method is independent of the parametric form of the diameter function and the spatial distribution of galaxies and is insensitive to Malmquist bias. We include information on the galaxy rotation velocities; unlike Tully-Fisher, however, we retain a fully non-parametric treatment. We find H0=66±6H_0=66\pm6 km/s/Mpc, somewhat larger than previous results using galaxy diameters.Comment: 4 pages, 1 figure, Cosmic Flows Workshop, Victoria B.C. Canada, July 1999, ed. S.

    Star Cluster Survival in Star Cluster Complexes under Extreme Residual Gas Expulsion

    Full text link
    After the stars of a new, embedded star cluster have formed they blow the remaining gas out of the cluster. Especially winds of massive stars and definitely the on-set of the first supernovae can remove the residual gas from a cluster. This leads to a very violent mass-loss and leaves the cluster out of dynamical equilibrium. Standard models predict that within the cluster volume the star formation efficiency (SFE) has to be about 33 per cent for sudden (within one crossing-time of the cluster) gas expulsion to retain some of the stars in a bound cluster. If the efficiency is lower the stars of the cluster disperse mostly. Recent observations reveal that in strong star bursts star clusters do not form in isolation but in complexes containing dozens and up to several hundred star clusters, i.e. in super-clusters. By carrying out numerical experiments for such objects placed at distances >= 10 kpc from the centre of the galaxy we demonstrate that under these conditions (i.e. the deeper potential of the star cluster complex and the merging process of the star clusters within these super-clusters) the SFEs can be as low as 20 per cent and still leave a gravitationally bound stellar population. Such an object resembles the outer Milky Way globular clusters and the faint fuzzy star clusters recently discovered in NGC 1023.Comment: 21 pages, 8 figures, accepted by Ap
