Avoiding the Pheidippides effect : how theories contribute to endurance trail practice

Ultra endurance sport has shown a significant increase during the last couple of decades. This paper focuses on theories which explain the phenomenal efforts ultra endurance athletes face when running extreme distances. These ultra athletes have to endure physical pain and mental distress for long hours or even days before crossing the finishing line. This extreme running on technical terrain requires considerable physiological effort (Millet, Hoffman, & Morin, 2012). Freund et al. (2012), states that as a consequence of running such distances, runners will experience muscle soreness, cramps, ruptured muscle fibres that lead to myalgia and myofascial pain, compartment syndrome, inflammation of tendons and joint capsules, and fatigue fractures. And yet, none of them succumb to their injuries or exhaustion under normal conditions, as in the case of Pheidippides. Various theories argue that the body is a high functioning machine which depends on physical measures to determine its efficiency while others put the brain as central to endurance practice and argue that the brain is the ultimate regulator which is there to protect the body. The athlete can never be harmed as the brain is taking measures so that body systems are never in distress. The beating heart is protected and catastrophe cannot occur. This paper illustrates various diverse theories which posit different arguments regarding extreme running and how it is actually achievable, without the athlete perishing due to the effort.peer-reviewe

Hedonic Price Analysis of Thoroughbred Broodmares in Foal

Thoroughbred broodmares are the foundation of a successful racing operation. This study estimated the impact of breeding, racing, genetic, and market characteristics on broodmare auction prices. Data represent 298 broodmares in foal that were sold in Keeneland's 2005 sale. Prices were most responsive to the sire's stud fee and the broodmare's age, with pronounced day-of-sale effects. Overall valuation structure appeared similar to Neibergs' results using 1996 data. Out-of-sample forecasts were far superior to naive forecasts, but were not accurate enough to use in isolation from other decision aids such as visual inspection of the horse.broodmare, Thoroughbred horses, hedonic price analysis, forecasting, Demand and Price Analysis,

When decision support systems fail: insights for strategic information systems from Formula

Decision support systems (DSS) are sophisticated tools that increasingly take advantage of big data and are used to design and implement individual - and organization - level strategic decisions . Yet, when organizations excessively rely on their potential the outcome may be decision - making failure, particularly when such tools are applied under high pressure and turbulent conditions. Partial understanding and unidimensional interpretation can prevent learning from failure. Building on a practice perspective, we study an iconic case of strategic failure in Formula 1 racing. Our approach, which integrates the decision maker as well as the organizational and material context , identifies three interrelated sources of strategic failure that are worth investigation for decision - makers using DSS and big data: (1) t he situated nature and affordances of decision - making ; (2) t he distributed nature of cognition in decision - making; and (3) the performativity of the DSS. We outline specific research questions and their implications for firm performance and competitive advantage. Finally, we advance an agenda that can help close timely gaps in strategic IS research

Hedonic Price Analysis of Thoroughbred Broodmares in Foal

Thoroughbred broodmares are the foundation of a successful racing operation. This study estimated the impact of breeding, racing, and market characteristics on broodmare auction prices. Data represent 604 in-foal broodmares sold in Keeneland’s 2005 sale. Prices were highly responsive to the sire’s stud fee, the broodmare’s age, and progeny performance in graded stakes races, with pronounced day-of-sale effects. The stud fee marginal value was substantially lower than one break-even estimate, suggesting possible disincentives for investment in stallion services. Out-of-sample forecasts were far superior to naïve forecasts but were not accurate enough to use in isolation from other decision aids.broodmare, forecasting, hedonic price analysis, Thoroughbred, Agribusiness, Livestock Production/Industries,

SB 106 Congressional and state legislative districts; standards and criteria

This report examines Senate Bill (SB) 106, introduced during the 2018 Virginia General Assembly session to address the criterion of redistricting and the specific impact on racial and ethnic minorities. This legislation is a direct response to previous legislative attempts to address gerrymandering and remains an evolving issue in the Commonwealth

Firm technological responses to regulatory changes: A longitudinal study in the Le Mans Prototype racing

Despite the critical role of regulations on competition and innovation, little is known about firm responses and related effects on performance under regulatory contingencies that are permissive or restrictive. By longitudinally investigating hybrid cars competing in the Le Mans Prototype racing (LMP1), we counter-intuitively suggest that permissive regulations increase technological uncertainty and thus decrease the firms’ likelihood of shifting their technological trajectory, while restrictive regulations lead to the opposite outcome. Further, we suggest that permissive regulations favour firms that innovate their products by sequentially upgrading core and peripheral subsystems, while restrictive regulations—in the long term— favour firms upgrading them simultaneously. Implications for theory and practice are discussed

Inter-CubeSat Communication with V-band "Bull's eye" antenna

We present the study of a simple communication scenario between two CubeSats using a V-band “Bull's eye” antenna that we designed for this purpose. The return loss of the antenna has a -10dB bandwidth of 0.7 GHz and a gain of 15.4dBi at 60 GHz. Moreover, the low-profile shape makes it easily integrable in a CubeSat chassis. The communication scenario study shows that, using 0.01W VubiQ modules and V-band “Bull’s eye” antennas, CubeSats can efficiently transmit data within a 500 MHz bandwidth and with a 10-6 BER while being separated by up to 98m, under ideal conditions, or 50m under worst case operating conditions (5° pointing misalignment in E- and H-plane of the antenna, and 5° polarisation misalignment)

Gamification of sports media coverage: an infotainment approach to Olympics and Football World Cups

Sports media coverage of mega-events is partly oriented to gamification, the use of game elements and game design techniques in non-gaming contexts. This infotainment approach to events has been developed by media outlets as an original and effective way to capture wider audience attention and to place events in context before a competition starts. This article examines 28 gamified sports pieces developed by media outlets from seven countries during the last two Olympics (2016 Summer Olympics in Rio and 2018 Winter Olympics in Pyeongchang) and Football World Cups (2014 in Brazil and 2018 in Russia). This sample comprises two categories following Ferrer-Conill (2015): “gamified pieces” (game like elements that are part of a bigger interactive feature) and “newsgames” (more sophisticated pieces often included in complex graphics or multimedia content). The results show that, despite its entertaining formula, gamification serves mainly informational purposes and adds value to sports coverage. Especially in the Summer and Winter Olympics, gamified sports pieces tend to be explanatory and data-driven in order to inform the audience about nonmainstream sports
