The 1991 jerk was obvious in the Y component measured but not clear for the Z component. Rapid changes in the Z components were ubiquitous around 2000-2001, but not seen for the Y component. External effects were removed from the monthly means by comparing the monthly mean of the geomagnetic field components at the observatories with the monthly time series of the A_p geomagnetic index. However, some examples were analyzed and showed whether external effects were removed or not, there was no marked distinction in determining the jerks in China for the Y component and the Z component of the geomagnetic field. Finally, the isolines of the first differences of the annual means were used to analyze the spatial and temporal distributions of the jerks.展开更多

The results show that the earthquake tendency estimation of Chinese Mainland is for strong earthquakes to occur in the active stage, and that there is still potential for the occurrence of a Ms8.0 large earthquake in Chinese Mainland after the 2001 Western Kuulun Mountains Pass earthquake. However the phenomena that many large earthquakes occurred around Chinese Mainland, and the 6-year long quietude of Ms7.0 earthquake and an obvious quietude of Ms5.0 and Ms6.0 earthquakes during 2002- 2007 led to the distinctly lower forecast estimation of earthquake tendency in Chinese Mainland after 2006. The middle part in the north-south seismic belt has been designated a seismic risk area of strong earthquake in recent years, but, the estimation of the risk degree in Southwestern China is insufficient after the Ning＇er Ms6.4 earthquake in Yunnan in 2007. There are no records of earthquakes with Ms ≥ 7.0 in the Longmenshan fault, which is one of reasons that this fault was not considered a seismic risk area of strong earthquakes in recent years.展开更多

In this case report, an angiolipoma was diagnosed preoperatively by imaging （including CT scans, abdominal echo, barium enema, and colonoscopy）. This pathology was confirmed postoperatively. Computed tomography scan, abdominal echo, and barium enema images were presented.展开更多

According to the research achievement distribution situation, tourism development planning research can be divided into initial stage（ 1985-1998）, development stage（1999-2004） and prosperous stage（2005 till now）. The research achievement has the features of earlier academic research start, slow quantity increase, rapid growth of newspaper quantity, wide distribution of region, research achievement total increase speed slower than social scientific research achievement quantity growth. The research has three aspects of problems： one is insufficient academic research system; two is report lacks of depth, continuity and unity; three is research achievement has overall decreasing trend. The domestic tourism development planning should strengthen the theoretical research, combine with theory and practice; strengthen thematic reports, mining depth information, and give full play to supervision function.展开更多

Although entrepreneurship represents a rapidly expanding phenomenon, women meet specific difficulties that explain this lack of exploitation by the economy, The Global Entrepreneurship Monitor （GEM）, a not-for-profit academic research consortium, published its annual report which mentioned in particular a difference between female and male entrepreneurship. According to these results, it can be noticed that the typical profile of the female entrepreneur differs from that of her male counterpart. In Switzerland, those differences can be situated at three levels： （I） In the first place, a natural difference of the female entrepreneurship at the level of activities （service activities, low-added value, and low potential of job creation）; （2） Secondly, a difference in motivation/commitment （part-time work, start-up funds available, skills, received opportunities, and fear of failure）; and （3） Thirdly, a difference at the level of insertion （revealing the importance of networking, access to financing and structures of encouragement）. The present communication points up a typical profile of the woman entrepreneur in Switzerland. The authors also intend to identify the kind of obstacles female entrepreneur is likely to meet as well as the existing initiatives to exceed stereotypes by taking into account her specificities. There are several supports and measures intended to help women entrepreneurship concerning the following aspects： better time management; adapted following and training structures; access to easier financing; and better visibility and networking.展开更多
