[Method] With combination of non-structural and structured approach to design questionnaires, tourism image of Xi'an was explored using the SPSS software from both the qualitative and quantitative analyses. [Result] Xi'an tourism images serve a heritage historical monuments atmosphere with the Terracotta Warriors, City Wall, Big Wild Goose Pagoda,Huaqing Hot Springs, presenting a positive feeling among tourists in general. In the dissemination of travel, tourism infrastructure construction, tourism transportation,travel services have negative effects on the image of Xi'an tourism. [Conclusion]The evaluation on the tourism resources is highly spoken of by tourists than the scenic spot, indicating that despite high visibility of tourism resources in Xi'an, it has not formed strong core competitiveness and a complete tourism industrial chain. It is necessary to take the right marketing strategies to enhance tourist familiarity to Xi'an. Tourists demands, therefore, should be well considered in developing Xi'an scenic spots and new tourism products and projects be focused on to improve tourists' satisfaction.展开更多

The conformation of self-attractive semiflexible polymers depends on bending energy and self-attractive interactions between monomers in polymer chains. A three-stage process of toroid formation for self-attractive semiflexible chains is shown: several isolated toroids, a loose toroid structure, and a compact toroid structure. Utilizing the compact toroid conformations of self-attractive semiflexible chains, we can control effectively the spatial distributions of nanoparticles in self-attractive semiflexible polymer nanocomposites, and an unconventional toroid structure of nanoparti- cles is observed.展开更多

Many studies have investigated the cooling effects of urban parks; however, little attention has been given to park landscape structure. Based on landscape metrics, this study has explored the influences of the park landscape structure on its inner thermal environment, taking heavily urbanized Beijing Municipality in China as the study area. Three indices, including the percentage of landscape (PLAND), landscape shape index (LSI) and aggregation index (AI), were used to measure the composition and configuration characteristics of the landscape components inside the parks. The indices were calculated for five landscape types being interpreted from Quickbird images. Urban thermal conditions were measured using the land surface temperature (LST) derived from Landsat TM images. The results showed that the park LST had a negative relationship with the park size, but no significant relationship was found with park shape. For the park's interior landscape, however, the configuration and composition characteristics of the landscape components inside the park explained 70% of the park LST variance. The area percentage of water bodies and the aggregation index of woodland were identified as the key influencing characteristics. In addition, when the composition and configuration characteristics of the park landscape components were separately considered, the configuration characteristics (LSI and A1) explained approximately 54% of the variance in park LST, which was comparable with that explained by the composition characteristics (PLAND). Thus, this study suggested that an effective and practical way for urban cooling park design is the optimization of spatial configuration of landscape components inside the park.展开更多

This work envisages the discrepancies between social knowledge and the material world itself. The crucial conclusion reads as follows: Our image of reality is mostly based on our interests and desires and does not rely on thorough research. There are two types of such representations: utopia and ideology. The first of them, less interesting for us, is the type of ideas which can revolutionize a social being. The second one is a particular set of visions which can never be realized but on the other hand they act as common knowledge (general knowledge of the world)--stabilizing the social structure by presenting it with a holistic image of the world. Taking the above into consideration, how is it possible that representations, being so distant from reality (creating a completely separate "world"), basically enable efficient functioning in it? Ideology, being the foundation of the society's functioning space, should always be tautological, in the sense that for the participants of the given world's image (creation as it is), it should define the being in a comprehensive and adequate way (in Thomas Aquinas spirit). What is more, it would always be true. We should also mention that the main tools of ideology, understood this way, are specific definitions and the extrapolation of sense. The purpose of this lecture is to prove that it is possible for ideology to come to life, only when the individuals who acknowledge it will consider their image of reality proper. The above ideological system should be understood as the obviousness of description of the surrounding world which in return makes unreflective functioning in reality possible. This obviousness of the presented world will be referred to as social safety.展开更多

The buckling of knitted fabric sheets subjected to simple shear in the wale direction is investigated analytically in consideration of the large deformation of fabric sheet in critical configuration. The theory on instability of finite deformation is applied to the analysis. All the stress boundary conditions of knitted fabric sheet are satisfied. An equation to determine the buckling direction angle is derived. It is shown that there are two possible buckling modes, flexural mode and barreling mode. The buckling condition equations for the flexural mode and barreling mode are also obtained respectively. Numerical illustrations reveal that only the flexural mode can actually occur and the barreling mode cannot, which agrees with the experimental observations. For a permitted buckling mode on margin boundaries, the critical value of shear amount and the buckling direction angle can be determined.展开更多

Using examples of award-winning young authors--Bojan Krivokapic, Mirko Bozic, and Sima Majic, different types of so-called engaged poetry are indicated. This kind of poetry is used to subtly, critically, or in a very subversive way relate to the existing world, but also a new postmodern identity is formed through specific and carefully chosen poetic lexis, deprived of any kind of structure or limitation. The poetry of mentioned authors is used as a provisory example in order to indicate that post-war period (as well as postmodern time) changes the perception of identity, from nationally and politically oriented structure to individual and subversive, conventions-free comprehension of Oneself. Although the three authors are very different in style and expression, what brings them together is tendency to escape conventional and traditional cultural images in order to emphasize the importance of Being Different, but Equally Rightful.展开更多
