    The role of the horse in Europe. Editorial

    No full text
    The horse has a unique place in European society. Historically, it has played a major part in shaping political and agricultural advances. Today, the horse has diverse roles ranging from the companion and leisure horse, to the sporting athlete. The horse continues to work on the land in many European countries, it serves in the police and the armed forces, and in some regions is a source of food. This has resulted in a vast range of horse-human interactions and relationships. Despite the long association between man and the horse we still have a great deal to learn about their behaviour and the constraints that domestication has placed on them. The WATHAM Symposium on “The Role of the Horse in Europe”, organized in association with the Anthrozoology Institute at the University of Southampton, brought together researchers involved in the student of equine behaviour management and horsehuman interactions to present some of their recent work and to identify fruitful areas for future research. In addition to the main programme papers, the Symposium also featured a series of poster presentations on a range of topics including the evolution and domestication of horses; their husbandry, behaviour and welfare; and the role of the horse in modern society. The horse industry, and indeed, equine research, appears to be very fragmented by both discipline and country; and European collaboration provides a greater research potential than exists within countries or disciplines. The WALTHAM Symposium was successful, not only in highlighting common areas of interest, but also in revealing gaps in our knowledge where the paucity of information stands a barrier to the advancement of the equine industry, as a whole, across Europe

    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

    Diamond growth in a novel low pressure flame

    Get PDF
    Diamond growth using a new low-pressure combustion technique is reported. A large-area hydrogen/oxygen flame is used as the source of atomic hydrogen. Methane diluted in hydrogen is injected into the flame near a heated silicon substrate, on which diamond crystallites nucleate and grow. This technique is potentially capable of large-area film growth, since atomic hydrogen can be generated uniformly over arbitrarily large areas

    Not Quite Filling The Gap: Why the Miscellaneous Expense Allowance Leaves the NCAA Vulnerable to Antitrust Litigation

    Get PDF
    Throughout its history, the National Collegiate Athletic Association (NCAA) has been repeatedly accused of violating antitrust law in a range of different ways—restricting television broadcasts, limiting coaches’ salaries, and capping the amount of athletic scholarships. Most recently, in the case of White v. NCAA, a class of plaintiffs argued that the NCAA’s artificial limitation on student-athlete compensation violated antitrust law. Although this case settled before trial, it represented a major victory for student-athletes. The NCAA is now considering a proposal— the Miscellaneous Expense Allowance (“MEA”)—that would raise the NCAA’s artificial cap on athletics-related financial aid by $2000. This legislation is partially aimed at protecting the NCAA from further antitrust liability, but it does not quite fill the gap. After providing a brief history of college athletics and student-athlete compensation, this Note then examines the mechanics of antitrust law and how courts have applied antitrust law in the context of the NCAA. This Note then argues that a hypothetical class of student-athletes could still bring a viable antitrust claim against the NCAA, even if the MEA is passed. Subsequently, this Note analyzes the arguments on both sides that would arise in such a hypothetical lawsuit

    Tracking and data systems support for the Helios project. Volume 3: DSN support of Project Helios May 1976 - June 1977

    Spacecraft extended mission coverage does not generally carry a high priority, but Helios was fortunate in that a combination of separated viewperiods and unique utilization of the STDN Goldstone antenna have provided a considerable amount of additional science data return, particularly at key times such a perihelion and/or solar occultation

    Autonomous control procedures for shuttle rendezvous proximity operations

    Get PDF
    The results are presented of a study which uses fuzzy sets to model a Space Shuttle pilot's reasoning and actions while performing rendezvous proximity operation maneuvers. In this model fuzzy sets are used to simulate smooth and continuous actions as would be expected from an experienced pilot and to simulate common sense reasoning in the decision process. The present model assumes visual information available to the Shuttle pilot from the Shuttle Crew Optical Alignment Sighting (COAS) device and the overhead window and rendezvous radar sensor information available to him from an onboard display. This model will be used in a flight analysis simulator to perform studies requiring a large number of runs, each of which currently needs an engineer in the loop to supply the piloting decisions. This work has much broader implications in control of robots such as the Flight Telerobotic Servicer, in automated pilot control and attitude control, and in advisory and evaluation functions that could be used for flight data monitoring or for testing of various rule sets in flight preparation

    Interdisciplinary approaches to zoonotic disease

    Get PDF
    Zoonotic infections are on the increase worldwide, but most research into the biological, environmental and life science aspects of these infections has been conducted in separation. In this review we bring together contemporary research in these areas to suggest a new, symbiotic framework which recognises the interaction of biological, economic, psychological, and natural and built environmental drivers in zoonotic infection and transmission. In doing so, we propose that some contemporary debates in zoonotic research could be resolved using an expanded framework which explicitly takes into account the combination of motivated and habitual human behaviour, environmental and biological constraints, and their interactions
