The relation between the temperature in January and July are discussed by using the wavelet. The results show that the trend phase in July and January are nearly in-phase in Southwest and South China, but are out-of-phase in other regions. Reconstruction of original temperature series in each of the regions indicates that their change trends are consistent with the original temperature series.展开更多

In Albania, there are small and medium enterprises （businesses）. Although we have a high degree of business bankrupt, many businesses are reinforcing their competitive positions in market. In these conditions, a new appropriate organizational structure often plays a crucial role in managing the challenges. While the finn grows, at the same time grows the need for organization, involvement and leadership. In today＇s changing times, effective leadership is a key component of organizational success. Even if management is the key of operation and the standard operating procedures, our study shows that the manager always need leader＇s power. In today＇s global marketplace, organizations that strategically focus on building leadership capacity for the future will reap the benefits in the years to come. New trends in business development, of course have increased requirements for local managers. The organizations are under pressure to show return on investment for training and development. Although positive trends, problems which management is faced are more challenging than the degree of preparation and performance that they offer, so their qualitative qualification remains the continuous preoccupation as the role of our school is in this direction. From this point of view, education in distance can be considered as complementary approach and in some conditions as a worthy replacement of direct education, which still dominates educative systems in Albania.展开更多
A comprehensive precipitation trend and periodic analysis at the seasonal scale on a 286year data series （1724-2009） for Beijing are presented using linear regression, 11-year moving averages, Mann-Kendall test and ...A comprehensive precipitation trend and periodic analysis at the seasonal scale on a 286year data series （1724-2009） for Beijing are presented using linear regression, 11-year moving averages, Mann-Kendall test and continuous Morlet wavelet analysis. We found that in the past 300 years precipitation has increased except during winter. There were strong increasing trends after the 1780s in both summer and annual precipitation data series and the trend was significant for a longterm period. The abrupt points of summer and annual data series of precipitation are 1764 and 1768 respectively, after that, the trend changed from decreasing to increasing. It shows different periodic traits in four seasons respectively： 30–170 years, 80–95 years, 75–95 years and 55–65 years are considered to be the strongest period in spring, summer, autumn and winter. One hundred and fiftythree years, 85 years, 83 years and 59 years are the first order main periods in spring, summer, autumn and winter, respectively. The trend and period of annual precipitation are mainly impacted by rainfall in summe. According to the first main period of 85 years in both summer and annual precipitation data series, Beijing will experience a time period of less precipitation in 2009–2030.展开更多
