To date, only two scientific publications have attempted to review the main findings of studies published in this area. However, one of them was published about 20 years ago, when women＇s football was still in its infancy and there were only a few studies to report on. The other review was more recent. Nonetheless, its main focus was on the game and training demands of senior elite female players. Thus, information on female footballers of lower competitive levels and younger age groups was not included. Consequently, an updated review is needed in this area. The present article therefore aims to provide an overview of a series of studies that have been published so far on the specific characteristics of female football players and the demands of match-play. Mean values reported in the literature for age （12-27 years）, body height （155-174 cm）, body mass （48-72 kg）, percent body fat （13%-29%）, maximal oxygen uptake （45.1-55.5 mL/kg/min）, Yo-Yo Intermittent Recovery Test Level l （780-1379 m）, maximum heart rate （189-202 bpm）, 30 m sprint times （4.34-4.96 s）, and counter- movement jump or vertical jump （28-50 cm） vary mostly according to the players＇ competitive level and positional role. There are also some special considerations that coaches and other practitioners should he aware of when working with female athletes such as the menstrual cycle, potential pregnancy and lactation, common injury risks （particularly knee and head injuries） and health concerns （e.g., female athlete triad, iron deficiency, and anemia） that may affect players＇ football performance, health or return to play. Reported mean values for total distance covered （4-13 km）, distance covered at high-speed （0.2-1.7 km）, average/peak heart rate （74%-87%/94%-99% HRmax）, average/peak oxygen uptake （52%-77%/96%-98% VO2max）, and blood lactate （2.2-7.3 mmol/L） during women＇s football match-play vary according to the players＇ competitive level and positional role. Methodological differences may account for the discrepancy of the reported values as well. Finally, this review also aims to identify literature gaps that require further scientific research in women＇s football and to derive a few practical recom-mendations. The information presented in this report provides an objective point of reference about player characteristics and game demands at various levels of women＇s football, which can help coaches and sport scientists to design more effective training programs and science-based strategies for the further improvement of players＇ football performance, health, game standards, and positive image of this sport.展开更多

It is a type of logic that recognizes more than simple true and false values. Linguistic variables can be represented with degrees of truthfulness and falsehood by using fuzzy logic. Like other artificial intelligence techniques, the fuzzy logic is used in many different areas. In computer game industry, it can be used to develop artificial intelligence based games. In this paper, the author discusses about usage of the fuzzy logic technique in computer games and developed a basic game based on the fuzzy logic. In this game, a computer controlled character can behave differently according to changing situations.展开更多

But, in fact, governments own the rights to control the operation of rural enterprises to a large extent. Govemments encourage and lead the reform of property rights of rural enterprises. Why governments are willing to give up vested interests, and actively promote the reform of property rights of rural enterprises？ This seems to be the key to explain the reform of property rights of rural enterprises. This paper puts forward the hypothesis, uses mathematical models and statistical analyses, and adopts relevant data to verify the needs of governments for fiscal targets, and the rationality of their behavior actively encourages and promotes reconstruction during the reform for maximizing their interests.展开更多

Against the global trend of culture heritage nationalization context, via the new media platform, the performative staging of individual emotions and reverie in the market society2, the longings to redeem various alienation in a vertical modernity3, as well as the yearnings for emotional balance in a burgeoning feministic modernity, all integrate with each other and together generate a restless transforming memory for kunqu. Just like a misty veil, this complex, contentious, contradictory and long-lasting collective memory-making process blurs kunqu＇s appearance, expands its layers, and ultimately generates a cultural myth. With detailed case studies this paper aims to reflect upon the deep reasons for the kunqu myth and to probe the transformative powers of a performative space in enabling remembrance and/or forgetting.展开更多
