    Marketing Recreation: Unique Characteristics of a Service Market Orientation

    Get PDF
    The marketing of recreation is unique and demands special consideration when compared with other products and services. Although general marketing theories and techniques seem to be appropriate, they tend to be more product oriented. Service marketing has far more relevance as a base concept to build upon to identify new marketing theories and techniques to accommodate this different subject matter area

    Image Analysis of Fitness Agencies: Implications for Marketing Strategies

    Get PDF
    The fitness marketplace is becoming more competitive and agencies now are starting to more closely examine their image(s) which are held by target markets. This study examined the image of 10 fitness as held by one target market--the college-aged, student, fitness A familiarity-favorability analysis and index technique was developed and refined. Seven of ten agencies were found to have an image problem. Implications and strategies are discussed

    Universal properties of the near-horizon optical geometry

    Full text link
    We make use of the fact that the optical geometry near a static non-degenerate Killing horizon is asymptotically hyperbolic to investigate universal features of black hole physics. We show how the Gauss-Bonnet theorem allows certain lensing scenarios to be ruled in or out. We find rates for the loss of scalar, vector and fermionic `hair' as objects fall quasi- statically towards the horizon. In the process we find the Lienard-Wiechert potential for hyperbolic space and calculate the force between electrons mediated by neutrinos, extending the flat space result of Feinberg and Sucher. We use the enhanced conformal symmetry of the Schwarzschild and Reissner-Nordstrom backgrounds to re-derive the electrostatic field due to a point charge in a simple fashion

    A Note on the Instability of Lorentzian Taub-NUT-Space

    Full text link
    I show that there are no SU(2)-invariant (time-dependent) tensorial perturbations of Lorentzian Taub-NUT space. It follows that the spacetime is unstable at the linear level against generic perturbations. I speculate that this fact is responsible for so far unsuccessful attempts to define a sensible thermodynamics for NUT-charged spacetimes.Comment: 13 pages, no figure

    Simple generalizations of Anti-de Sitter space-time

    Full text link
    We consider new cosmological solutions which generalize the cosmological patch of the Anti-de Sitter (AdS) space-time, allowing for fluids with equations of state such that w≠−1w\neq -1. We use them to derive the associated full manifolds. We find that these solutions can all be embedded in flat five-dimensional space-time with −−+++--+++ signature, revealing deformed hyperboloids. The topology and causal-structure of these spaces is therefore unchanged, and closed time-like curves are identified, before a covering space is considered. However the structure of Killing vector fields is entirely different and so we may expect a different structure of Killing horizons in these solutions.Comment: 6 Pages, 5 Figures, Corrections and additions made for publication in Journal of Classical and Quantum Gravit
