A Cross-Cultural Analysis on Guasha Treatment from Hofstede's Value Dimensions

Nowadays,with the irresistible trend of globalization and more increasing cultural exchanges among different cultures,there are more and more contacts and collisions from different cultural backgrounds.People can derive a lot from different cultures through communication.But if people cannot understand other cultures'customs,religions,habits,and so on very well,people will be faced with cultural clashes.Guasha Treatmen is Zheng Xiaolong's classical movie,which tells us a judicial conflict owing to red scars on a boy's back.In the movie,because the boy catches a cold,Chinese immigrates performs Guasha treatment to cure the boy while American people believes that the boy is treated badly.For the Chinese family in the movie,Guasha treatment is only a traditional medical therapy,but American people assume that it is an illegal act as they cannot understand Chinese medical culture.Hence,there exists misunderstanding and cultural conflicts because of cultural differences.This paper will be analyzed from the perspective of Greet Hofstede's three value dimensions so as to help people face the contradiction and conflicts in the process of cross-cultural communication and improve the ability of intercultural communication.

THE DISTRIBUTIONAL DIMENSION OF FRACTALS

In the book [1] H.Triebel introduces the distributional dimension of fractals in an analytical form and proves that： for Г as a non-empty set in R^n with Lebesgue measure ｜Г｜ = 0, one has dimH Г = dimD Г, where dimD Г and dimH Г are the Hausdorff dimension and distributional dimension, respectively. Thus we might say that the distributional dimension is an analytical definition for Hausdorff dimension. Therefore we can study Hausdorff dimension through the distributional dimension analytically. By discussing the distributional dimension, this paper intends to set up a criterion for estimating the upper and lower bounds of Hausdorff dimension analytically. Examples illustrating the criterion are included in the end.

Dimensional Measurement of Complete-connective Network under the Condition of Particle’s Fission and Growth at a Constant Rate

We construct a complete-connective regular network based on Self-replication Space and the structural principles of cantor set and Koch curve. A new definition of dimension is proposed in the paper, and we also investigate a simplified method to calculate the dimension of two regular networks. By the study results, we can get a extension: the formation of Euclidean space may be built by the process of the Big Bang's continuously growing at a constant rate of three times.

On a Hypothetical Vector Field Associated with the Classic Electromagnetic Wave in a Space of Four Dimensions

In two previous papers [1] and [2], a structure for vector products in n dimensions was presented, and at the same time it was possible to propose the existence of a vector analogous to the curl of a vector field, for a space of four dimensions. In continuation of these works, the objective is to develop, through dimensional analogy, the idea of a hypothetical vector field, associated with the classical electromagnetic wave. This hypothetical field has a possible mathematical existence only when considering a space of four dimensions. The properties of the electromagnetic wave are preserved and equations with mathematical forms analogous to those of Maxwell’s equations are presented.

The Global Attractors and Dimensions Estimation for the Higher-Order Nonlinear Kirchhoff-Type Equation with Strong Damping

The initial boundary value problems for a class of high order Kirchhoff type equations with nonlinear strongly damped terms are considered. We establish the existence and uniqueness of the global solution of the problem by using prior estimates and Galerkin’s method under proper assumptions for the rigid term. Then the compact method is used to prove the existence of a compact family of global attractors in the solution semigroup generated by the problem. Finally, the Frechet differentiability of the operator semigroup and the decay of the volume element of linearization problem are proved, and the Hausdorff dimension and Fractal dimension of the family of global attractors are obtained.

Fractal Dimension in Animal Model of Alzheimer’s Dementia

The aim of this study was to qualitatively described effect of the oxidative stress, neurotransmission change and the neurodegeneration in animal model of chronic intoxication by aluminum. Electrocortical brain activity of animal model of stress and neurodegeneration is comparable with Alzheimer’s Dementia (AD). We used adult animals, during 6 weeks intraperitoneally treated with aluminum. Both animals and patients with Alzheimer’s Dementia have increased relative spectral power in delta range. By fractal analysis we described changes in electrocortical activity of aluminum intoxication animals compare to physiological control. We used change in delta range to calculate fractal dimension for the pathophysiological state of disease. We evaluate effect of stress and neurodegeneration, oxidative stress and accumulation of beta amyloid and neurofibrillary tangles as change in fractal dimension (FD). We conclude that change in fractal dimension could be used for prognosis of AD. Results show that decrease in fractal dimension could be used for evaluation of changes in neural activity in occurrence of AD.

A Case Study on Coca-Cola Company's Advertisements in China:Based on Hofstede's Cultural Dimensions

Globalization changes the business style of corporations.In modern society,entrepreneurs believe that it is important for companies to expand their business all over the world.However,an inevitable problem comes to managers' sight-cultural differences.Citizens in different countries have different norms,rules,symbols and values,which influence the business expansion of corporations in foreign countries.Therefore,it is crucial for translational corporations to introduce their products or services to foreign customers in proper ways and make customers accept them.Advertising plays an important role in this process because it delivers corporate image and corporate culture to customers.Meanwhile,Hofstede's cultural dimensions help managers analyze and deal with cultural differences when they are assigned to foreign countries for managing.In this paper,an analysis on the application of Hofstede's cultural mode based on a case study of Coca-Cola's advertisements will be conducted.It will be organized as follows:a literature review on Hofstede's cultural mode will be arranged in section one.Then,section two will discuss the application of Hofstede's cultural mode in China,and a case study of Coca-Cola's advertisements in China will be followed.In the end,a conclusion based on above findings will be summarized in section three.

Representations of Ten-Dimensional Levi Decomposition Lie Algebras

The authors have recently completed a partial classification of the ten-dimensional real Lie algebras that have the non-trivial Levi decomposition, namely, for such algebras whose semi-simple factor is so(3). In the present paper, we obtain a matrix representation for each of these Lie algebras. We are able to find such representations by exploiting properties of the radical, principally, when it has a trivial center, in which case we can obtain such a representation by restricting the adjoint representation. Another important subclass of algebras is where the radical has a codimension one abelian nilradical and for which a representation can readily be found. In general, finding matrix representations for abstract Lie algebras is difficult and there is no algorithmic process, nor is it at all easy to program by computer, even for algebras of low dimension. The present paper represents another step in our efforts to find linear representations for all the low dimensional abstract Lie algebras.

Non-Perturbative Guiding Center and Stochastic Gyrocenter Transformations:Gyro-Phase Is the Kaluza-Klein 5^(th) Dimension also for Reconciling General Relativity with Quantum Mechanics

The non perturbative guiding center transformation is extended to the relativistic regime and takes into account electromagnetic fluctuations. The main solutions are obtained in covariant form: the gyrating particle and the guiding particle solutions, both in gyro-kinetic as in MHD orderings. Moreover, the presence of a gravitational field is also considered. The way to introduce the gravitational field is original and based on the Einstein conjecture on the feasibility to extend the general relativity theory to include electromagnetism by geometry, if applied to the extended phase space. In gyro-kinetic theory, some interesting novelties appear in a natural way, such as the exactness of the conservation of a magnetic moment, or the fact that the gyro-phase is treated as the non observable fifth dimension of the Kaluza-Klein model. Electrodynamics becomes non local, without the inconsistency of self-energy. Finally, the gyrocenter transformation is considered in the presence of stochastic e.m. fluctuations for explaining quantum behaviors via Nelson’s approach. The gyrocenter law of motion is the Schrödinger equation.
