A landslide occurred in the filling body of the eastern part of the Panzhihua airport on October 3, 2009 （hereafter called the lo.3 landslide）. We conducted field survey on the landslide and adopted emergency monitoring and warning models based on the Internet of Things （loT） to estimate the losses from the disaster and to prevent a secondary disaster from occurring. The results showed that four major features of the airport site had contributed to the landslide, i.e, high altitude, huge amount of filling rocks, deep backfilling and great difficulty of backfilling. The deformation process of the landslide had six stages and the unstable geological structure of high fillings and an earthquake were the main causes of the landslide. We adopted relative displacement sensing technology and Global System for Mobile Communications （GSM） technology to achieve remote, real-time and unattended monitoring of ground cracks in the landslide. The monitoring system, including five extensometers with measuring ranges of 200, 450 and 7oo mm, was continuously working for 17 months and released 7 warning signals with an average warning time of about 26 hours. At 10 am on 6 December 2009, the system issued a warning and on-site workers were evacuated and equipment protected immediately. At 2：20 medium-scale collapse monitoring site, which proved the reliability pm on 7 December, a occurred at the No. 5 justified the alarm and and efficiency of the monitoring system.展开更多

Prior studies relating to gender roles in media coverage of sports have been typically centered on underrepresentation, negative stereotypical portrayals of female athletes, and iconic heroic portrayals of male athletes. However, few studies have examined media coverage of male participation in so-called ＂gender inappropriate＂ sports. This research seeks to fill a gap in literature by exploring gender cues presented in the televised coverage of male and female figure skating events in the 2010 Winter Olympic Games. The findings from this research indicate that male athletes who cross gender barriers to participate in a feminine sport are likely to receive gender-marked stereotypical televised coverage. Much of the significant findings indicate that male figure skaters were visually and verbally portrayed as more feminine than the female figure skaters. The study opens lines of research into how sports are portrayed and could potentially influence sport marketing, athlete endorsements, athlete wardrobe, and other decisions made by the media, athletes, and individuals working in the sport industry.展开更多
