被动性社交网站使用对用户地位商品偏好的作用机制研究

基于社会比较理论,探讨了个体被动性社交网站使用对地位商品消费行为的影响及作用机制。通过三个用户行为实验分析发现,被动性社交网站使用相较于未使用、高强度被动性使用相较于低强度,均能增加个体对地位商品的购买意愿;上行社会比较和自尊在被动性社交网站使用影响地位商品消费的过程中起链式中介作用;进一步地,自我与他人相似性通过影响个体上行社会比较倾向和自尊水平进而对链式中介路径起调节作用。研究对社交网站使用行为与消费行为之间的联系及影响机制有了全面深刻的认知,对企业通过社交网站进行营销活动提供了有价值的参考。

Chinese Fuzzy Ontology Mapping Based on Support Vector Machine

Taking into account that fuzzy ontology mapping has wide application and cannot be dealt with in many fields at present,a Chinese fuzzy ontology model and a method for Chinese fuzzy ontology mapping are proposed.The mapping discovery between two ontologies is achieved by computing the similarity between the concepts of two ontologies.Every concept consists of four features of concept name,property,instance and structure.First,the algorithms of calculating four individual similarities corresponding to the four features are given.Secondly,the similarity vectors consisting of four weighted individual similarities are built,and the weights are the linear function of harmony and reliability.The similarity vector is used to represent the similarity relation between two concepts which belong to different fuzzy ontolgoies.Lastly,Support Vector Machine(SVM) is used to get the mapping concept pairs by the similarity vectors.Experiment results are satisfactory.

Changes in Post-World War II： Italians in Rochester, N.Y.

This article examines the major similarities and differences among Italians who migrated to Rochester, N.Y., before World War II and post-World War Ⅱ. It offers explanations on the similarities and differences among these two groups of migrants. Investigation of historical, sociological, and anthropological sources along with interviews among both populations provides abundant data bearing on the investigation. The successful completion of the research reported in this article has major bearing on the issue of migration itself, theories in history, sociology, and anthropology, and even on social psychological understanding of how choices are made and identity is formulated.

Humanistic cultural tradition background and research of similarities and differences between Chinese and Western music

Music is an integral part of culture, culture represents the spirit of a country, so from this point of the music, we can get a glimpse of the cultural characteristics of a country. Music, broadly speaking, I think it should be the extension of culture, is a crystalline form of the essence which the culture conceived. This article discusses the musical and cultural ties, the characteristics of Chinese and Western musical culture, contacts the cultural background of Chinese and Western music culture, making more in-depth understanding.

Interaction Between Tax Compliance and Tax Administration in Lithuania： Tax Evasion Aspect

Tax payers and tax administrators are the main structural groups in tax system. They interact and have an impact on each other＇s actions following by tax compliance or tax non-compliance. However, no wider study encompassing both tax payers and tax administrators has been conducted in Lithuania. Since a survey of all participants in the tax system would require substantial time, human, and financial resources, during the first study, only one group, tax payers, was surveyed. During the second study, tax administrators were surveyed along with the tax payers. The present study has the following objectives： to describe the problem of tax evasion in the context of attitudes and behaviours of participants in the tax system; to estimate the tax compliance and evasion situation in Lithuania on the basis of attitudes and behaviours of tax payers; to establish how tax administrators estimate the tax compliance （evasion） situation in Lithuania; to assess the relationship between tax administrators and tax payers; to determine similarities and differences of their attitudes; to assess the key aspects of tax evasion; and to identify measures for the solution of this problem.

Genetic variation in birds in relation to predation risk by hawks： A comparative analysis

The level of genetic variation among individuals may affect performance by reducing the ability of prey to detect and escape from predators if lack of genetic variation reduces flight ability directly or indirectly through reduced parasite resistance. We investigated vulnerability of common avian prey species to predation by the sparrowhawk Accipiter nisus and the goshawk A. gentilis in relation to an index of genetic similarity among adults of potential prey species. We estimated a prey vulnerability in- dex that reflects the abundance of prey relative to the expected abundance according to local population density, and related this index to band sharing coefficients based on analyses of minisatellites for adults in local breeding populations. The prey vulnera- bility index was positively correlated with the band sharing coefficient in both predators, even when controlling for potentially confounding variables. These findings indicate that prey species with high band sharing coefficients, and hence low levels of genetic variation, are more readily caught by avian predators. Therefore, predation may constitute a major cost of low levels of genetic variation in extant populations of prey [Current Zoology 61（1）： 1-9, 2015].

Several Types of Similarity Solutions for the Hunter-Saxton Equation

We study separable and self-similar solutions to the Hunter-Saxton equation, a nonlinear wave equation which has been used to describe an instability in the director field of a nematic liquid crystal （among other applications）. Essentially, we study solutions which arise from a nonlinear inhomogeneous ordinary differential equation which is obtained by an exact similarity transform for the ttunter-Saxton equation. For each type of solution, we are able to obtain some simple exact solutions in closed-form, and more complicated solutions through an analytical approach. We find that there is a whole family of self-similar solutions, each of which depends on an arbitrary parameter. This parameteressentially controls the manner of self-similarity and can be chosen so that the self-similar solutions agree with given initial data. The simpler solutions found constitute exact soIutions to a nonlinear partial differential equation, and hence are also useful in a mathematical sense. Analytical solutions demonstrate the variety of behaviors possible within the wider family of similarity solutions. Both types of solutions cast light on self-similar phenomenon arising in the Hunter-Saxton equation.
