Internationalization versus Localization: The Case of Primary Education in Taiwan
Li-Ping Wang,Hsuanfu Ho
International Education Studies , 2012, DOI: 10.5539/ies.v5n4p39
Abstract: Internationalization is receiving increasing attention at academic institutions all over the world. Taiwan is no exception, where the government is promoting internationalization not only in higher education, but also at the primary education level. In this research we identified the key factors of the internationalization of primary education in Taiwan, calculated their relative importance, and determined their relationships with the various internationalization strategies being used in Taiwan. Questionnaires were administered to 300 school teachers, of which 246 were returned. AHP was adopted as the major instrument for determining the relative weight of each factor and strategy, and correspondence analysis was employed to investigate their respective relationships. Based on the findings, we provide suggestions for improving the internationalization of primary schools in Taiwan.
A New Group Key Agreement Protocol for Ad Hoc Networks
Li-Ping Zhang,Yi Wang
Journal of Communications , 2010, DOI: 10.4304/jcm.5.7.545-550
Abstract: A mobile ad hoc network is a collection of autonomous nodes that communicate with each other by forming a multi-top wireless network. Different from conventional wireless networks, the resource of the nodes in ad hoc networks is limited and there may be tens of thousands of low-power energy constrained nodes in ad hoc networks. As such, the costs of the nodes resource and the network size should be taken into consideration when constructing a group key agreement protocol in the ad hoc networks. In this paper, an efficient and scalable group key agreement protocol based on layer-cluster group model for mobile ad hoc networks was proposed. In this protocol, multi-linear map is employed on layer-cluster structure to establish and allocate group key. So that it can not only meet security demands of larger mobile ad hoc networks but also improve executing performance.
An ID-Based Authenticated Key Agreement Protocol for Wireless Sensor Networks
Li-Ping Zhang,Yi Wang
Journal of Communications , 2010, DOI: 10.4304/jcm.5.8.620-626
Abstract: Providing a suitable key establishment protocol in wireless sensor networks is challenging due to all the characteristics of these networks, such as limitations of power, computation capability and storage resources. This paper presents a novel key agreement protocol for wireless sensor networks. By applying the ID-based technique, a sensor node and a security manager can achieve key exchange and fast authentication. In this protocol the expensive operations are removed from sensor node side and a sensor node needs not to transmit its implicit certificate, so it reduces the energy cost of sensor nodes. We prove the security of our protocol in the random oracle model.
The Significance of the Natural World in The Education of Little Tree  [PDF]
Li-Ping Chang
Advances in Literary Study (ALS) , 2014, DOI: 10.4236/als.2014.22010

Forrest Carter’s The Education of Little Tree (ELT) was published as a memoir in 1976. Carter died in 1979, but his book gained in popularity, to win the American Booksellers Association Book of the Year award in 1991 and became a national best seller. The book explores the significance of nature and animals in a traditional Native American worldview, even as it espouses ecological consciousness via the education of Little Tree by his Cherokee grandparents. The Education of Little Tree has much to offer in its presentation of a Native American philosophy of life that includes caring for the earth and its creatures as well as other people, regardless of their skin color or ethnicity. This article aims to examine the ecological values portrayed by the traditional Cherokee way of life as presented in The Education of Little Tree.

Opinion Dynamics on Complex Networks with Communities


中国物理快报 , 2008,
Abstract: The Ising or Potts models of ferromagnetism have been widely used to describe locally interacting social or economic systems. We consider a related model, introduced by Sznajd to describe the evolution of consensus in the scale-free networks with the tunable strength (noted by Q) of communitystructure. In the Sznajd model, the opinion or state of any spins can only be changed by the influence of neighbouring pairs of similar connection spins. Such pairs can polarize their neighbours. Using asynchronous updating, it is found that the smaller the community strength Q, the larger the slope of the exponential relaxation time distribution. Then the effect of the initial up-spin concentration p as a function of the final all up probability E is investigatedby taking different initialization strategies, the random node-choseninitialization strategy has no difference under different community strengths, while the strategies of community node-chosen initialization and hub node-chosen initialization are different in final probability under different Q, and the latter one is more effective in reaching final state.
Optimum Design of 3-3 Stewart Platform Considering Inertia Property
Zhu-Feng Shao,Xiaoqiang Tang,Li-Ping Wang
Advances in Mechanical Engineering , 2013, DOI: 10.1155/2013/249121
Abstract: Optimum design is a pivotal approach to fulfill the potential advantages of the parallel manipulator in practical applications. This paper concerns the optimum design issue of the 3-3 Stewart platform considering the inertia property, in addition to the kinematic performance. On the basis of spherical usable workspace, global conditioning index (GCI) is analyzed. Atlases of the workspace and GCI are deduced with the established nondimensional design space. Further, after dynamic modeling, the global inertia index (GII) is deduced from the joint-space inertia matrix, and corresponding GII atlases are drawn. In particular, an example is presented to illustrate the process of obtaining the practical optimum results based on these non-dimensional atlases. Since both kinematic and dynamic properties are considered, the optimum result will possess comprehensive performance improvements. 1. Introduction The parallel manipulator usually consists of the base and the end effector, which are connected together with at least two identical kinematic chains. Its significant structure feature is the closed-loop kinematic chain. Compared with conventional serial manipulators, parallel manipulators possess some inherent potential advantages [1], such as high accuracy, improved stiffness, increased dynamics, compact structure with multiple degree of freedoms (DOF), and so on. As a result, parallel manipulators attract great academic attentions and are more and more widely adopted in industrial applications, namely, flight simulators [2], telescopes [3–5], and machine tools [6]. Optimum design of the parallel manipulator is recognized as an important theoretical issue, as well as a great practical approach to make full use of its potential advantages in practical applications [7, 8]. Optimization design of the parallel manipulator is always a challenging issue, which is mainly based on the kinematics now [9]. And several kinematic performance criteria could be involved, such as workspace [10], singularity [11], accuracy [12], stiffness [13], and conditioning index [14]. Among them, workspace and conditioning index are the two most important key criteria. On the other side, the dynamic performance of the parallel manipulator is analyzed and evaluated in a lot of works [15, 16]. However, little effort has been made on the dynamic optimum design. Inertia property is an important part of the manipulator dynamics, which shows its impacts in many ways [17, 18], such as mechanical resonance frequency, acceleration capability, and dynamic response. Inertia property has been
Identifying two-photon high-dimensional entanglement in transverse patterns
Gui-Fang Dang,Li-Ping Deng,Kaige Wang
Physics , 2005, DOI: 10.1016/j.physleta.2006.06.085
Abstract: We propose a scheme to explore two-photon high-dimensional entanglement associated with a transverse pattern by means of two-photon interference in a beamsplitter. We find that the topological symmetry of the angular spectrum of the two-photon state governs the nature of the two-photon interference. We prove that the anti-coalescence interference is the signature of two-photon entanglement. On the basis of this feature, we propose a special Mach-Zehnder interferometer incorporated with two spiral phase plates which can change the interference from a coalescence to an anti-coalescence type only for a two-photon entangled state. The scheme is simple and straightforward compared with the test for a Bell inequality.
Towards two-body strong decay behavior of higher $ρ$ and $ρ_3$ mesons
Li-Ping He,Xiao Wang,Xiang Liu
Physics , 2013, DOI: 10.1103/PhysRevD.88.034008
Abstract: In this work, we systematically study the two-body strong decay of the $\rho/\rho_3$ states, which are observed and grouped into the $\rho/\rho_3$ meson family. By performing the phenomenological analysis, the underlying properties of these states are obtained and tested. What is more important is that abundant information of their two-body strong decays is predicted, which will be helpful to further and experimentally study these states.
The endomorphism of Grassmann graphs
Li-Ping Huang,Benjian Lv,Kaishun Wang
Mathematics , 2014,
Abstract: A graph is called a pseudo-core if every endomorphism is either an automorphism or a colouring. In this paper, we show that every Grassmann graph $J_q(n,m)$ is a pseudo-core. Moreover, the Grassmann graph $J_q(n,m)$ is a core whenever $m$ and $n-m+1$ are not relatively prime, and $J_q(2pk-2, pk-1)$ is a core whenever $p,k\geq 2$.
