The concept of competitiveness influenced by many factors is analyzed in terms of terminology distinctions. This is the reason of numerous definitions of this term included in the first part of the paper, which varies according to the aspect of the analysis, analyzed marketing unit, tourism product, geographical unit, region, destination, or entities that offer an acceptable integrated product a package by specific indicators for comparison of elements of competitiveness. The first part of the article theoretically emphasizes the distinction in defining the concept of competitiveness from various aspects of the analyzed market subjects (different features and facilities provided), and from those aspects of their specific business relationship in the market. Special contribution to the study of competitiveness is contained in the second part of the paper that analyzes the existing situation of intermediation in the European tourism market. This research is based on using the data of descriptive statistics and the secondary research which gives insights into the business of travel agencies, using the data such as number of employees, annual personnel costs, and the average annual cost per person employed in travel agencies in some European countries. The changes in the environment, and the competition initiate a need for an analysis of the internal environment, travel agencies' tasks, and their organizational structure. Also, the results conducted research on a sample of 500 travel agencies in 20 European countries indicate the dominance of quality service, price, and value for money as key factors of demand for achieving the competitiveness. It indicates new trends focused on needs for more specific--integrated tourist products that ensure the quality of service, value for money, and for the time that tourists invest in their obtaining. 展开更多

From the 1960 s to 1970 s, North China has been hit by a series of large earthquakes. During the past half century,geophysicists have carried out numerous surveys of the crustal and upper mantle structure, and associated studies in North China.They have made significant progress on several key issues in the geosciences, such as the crustal and upper mantle structure and the seismogenic environment of strong earthquakes. Deep seismic profiling results indicate a complex tectonic setting in the strong earthquake areas of North China, where a listric normal fault and a low-angle detachment in the upper crust coexist with a high-angle deep fault passing through the lower crust to the Moho beneath the hypocenter. Seismic tomography images reveal that most of the large earthquakes occurred in the transition between the high-and low-velocity zones, and the Tangshan earthquake area is characterized by a low-velocity anomaly in the middle-lower crust. Comprehensive analysis of geophysical data identified that the deep seismogenic environment in the North China extensional tectonic region is generally characterized by a low-velocity anomalous belt beneath the hypocenter, inconsistency of the deep and shallow structures in the crust, a steep crustalal-scale fault,relative lower velocities in the uppermost mantle, and local Moho uplift, etc. This indicates that the lithospheric structure of North China has strong heterogeneities. Geologically, the North China region had been a stable craton named the North China Craton or in brief the NCC, containing crustal rocks as old as ~3.8 Ga. The present-day strong seismic activity and the lower velocity of the lower crust in the NCC are much different from typical stable cratons around the world. These findings provide significant evidence for the destruction of the NCC. Although deep seismic profiling and seismic tomography have greatly enhanced knowledge about the deep-seated structure and seismogenic environment, some fundamental issues still remain and require further work. 展开更多
