ABSTRACT

This study seeks to examine the influence of the cultural elements on international students’ country choice. It also examines whether individual values moderate the influence of cultural elements on the country choice of international students. Drawing upon a sample size of 223, the data was analysed using structural equation modelling technique. Among the five cultural elements, education, language and social institutions were found to have a positive significant influence on the international student’s country choice. When moderated by individual values education was found to be the only key significant value to international students when selecting a country to further their education. The cultural elements should be given much attention by marketers, government and managers of academic institutions. An improvement in the standards of education in developing countries would attract more students from developed countries.  相似文献

Does religion matter? Italians’ responses towards Muslim and Christian Arab immigrants as a function of their acculturation preferences     

《Int J Intercult Relat》2020

A 2 × 2 × 2 experiment examined the role of immigrants’ religion and perceived acculturation strategy on majority members’ attitudes. Acculturation strategies were manipulated along the two dimensions of contact and culture maintenance. Italian majority members (N = 247) read fictitious but seemingly real interviews with Arab immigrants, in which the immigrants’ religion (Muslim vs. Christian) and acculturation preferences (desire for contact and for culture maintenance) were manipulated. MANOVA showed a main effect of contact: majority members associated immigrants who were perceived to favour contact with more positive attitudes, empathy, trust, positive stereotypes and metastereotypes, and lower levels of threat. MANOVA also showed a main effect of culture maintenance: when immigrants were perceived to abandon their culture, majority members reported lower levels of symbolic threat and greater empathy towards them. A significant Religion x Culture maintenance interaction effect emerged on majority members’ stereotypes and contact intentions: Muslim immigrants who were perceived to abandon their heritage culture elicited more favourable responses than Muslim immigrants who were perceived to maintain their heritage culture. Taken together, these findings suggest that desire for intergroup contact amongst immigrants, independently of their religion, can promote harmonious intergroup relations with the majority group.  相似文献

Observer-based decentralized control of large-scale stochastic high-order feedforward systems with multi time delays     

Liang Liu  Shengyuan Xu  Xue-Jun Xie  Bing Xiao 《Journal of The Franklin Institute》2019,356(16):9627-9645

This paper investigates the problem of observer-based decentralized control for a class of large-scale stochastic high-order feedforward systems with multi time delays. By using the homogeneous domination idea and constructing the implementable observer, the decentralized output-feedback controller design scheme is firstly proposed. Then, with the aid of stochastic time delay system stability theory, the globally asymptotically stable in probability of the closed-loop system is verified by selecting an appropriate Lyapunov–Krasoviskii functional. Finally, an example is provided to demonstrate the efficiency of the proposed design method.  相似文献   

Synergetic governing controller design for the hydraulic turbine governing system with complex conduit system     

Jianzhong Zhou  Yuncheng Zhang  Yang Zheng  Yanhe Xu 《Journal of The Franklin Institute》2018,355(10):4131-4146

The hydraulic turbine governing system plays an indispensable role in maintaining the stability of electrical power system. In this paper, synergetic control theory is introduced to enhance the regulating ability of the hydraulic turbine governing system. For the purpose of describing the characteristics of objective system and deducing the synergetic control rule, a nonlinear mathematic model of a hydraulic turbine governing system with long tail race and two surge tanks is established. Furthermore, the nonlinear characteristic of the hydraulic turbine is described by six variable partial derivatives. For further investigation, the hydraulic turbine governing system is conducted to running under load condition when its coaxial generator connects to an infinite bus. Simulation experiments have been made under both load disturbance and three-phase short circuit fault conditions to compare the dynamic performances of proposed synergetic governing controller and classic PID controller. The results indicate that the proposed synergetic governing controller is an effective alternative in normal condition and a superior one in emergency. Moreover, the robustness of synergetic governing controller has also been discussed at the end of this paper.  相似文献   

New insights in stability analysis of delayed Lotka–Volterra systems     

Xu-Guang Li  Jun-Xiu Chen  Silviu-Iulian Niculescu  Arben Çela 《Journal of The Franklin Institute》2018,355(17):8683-8697

Most of the reported Lotka–Volterra examples have at most one stability interval for the delay parameters. Furthermore, the existing methods fall short in treating more general case studies. Inspired by some recent results for analyzing the stability of time-delay systems, this paper focuses on a deeper characterization of the stability of Lotka–Volterra systems w.r.t. the delay parameters. More precisely, we will introduce the recently-proposed frequency-sweeping approach to study the complete stability problem for a broad class of linearized Lotka–Volterra systems. As a result, the whole stability delay-set can be analytically determined. Moreover, as a significant byproduct of the proposed approach, some Lotka–Volterra examples are found to have multiple stability delay-intervals. To the best of the authors’ knowledge, such a characterization represents a novelty for having some insights in the population dynamics: in some situations, a longer maturation period of species is helpful for the stability of a population system.  相似文献

A new sensor selection scheme for Bayesian learning based sparse signal recovery in WSNs     

Bo Xue  Linghua Zhang  Weiping Zhu  Yang Yu 《Journal of The Franklin Institute》2018,355(4):1798-1818

In this paper, we address the issue of sparse signal recovery in wireless sensor networks (WSNs) based on Bayesian learning. We first formulate a compressed sensing (CS)-based signal recovery problem for the detection of sparse event in WSNs. Then, from the perspective of energy saving and communication overhead reduction of the WSNs, we develop an optimal sensor selection algorithm by employing a lower-bound of the mean square error (MSE) for the MMSE estimator. To tackle the nonconvex difficulty of the optimum sensor selection problem, a convex relaxation is introduced to achieve a suboptimal solution. Both uncorrelated and correlated noises are considered and a low-complexity realization of the sensor selection algorithm is also suggested. Based on the selected subset of sensors, the sparse Bayesian learning (SBL) is utilized to reconstruct the sparse signal. Simulation results illustrate that our proposed approaches lead to a superior performance over the reference methods in comparison.  相似文献   

University licensing and the flow of scientific knowledge     

Neil C. Thompson  Arvids A. Ziedonis  David C. Mowery 《Research Policy》2018,47(6):1060-1069

As university involvement in technology transfer and entrepreneurship has increased, concerns over the patenting and licensing of scientific discoveries have grown. This paper examines the effect that the licensing of academic patents has on journal citations to academic publications covering the same scientific research. We analyze data on invention disclosures, patents, and licenses from the University of California, a leading U.S. academic patenter and licensor, between 1997 and 2007. We also develop a novel “inventor-based” maximum-likelihood matching technique to automate and generalize Murray's (2002) “patent-paper pairs” methodology. We use this methodology to identify the scientific publications associated with University of California patents and licenses.Based on a “difference-in-differences” analysis, we find that within our sample of patented academic discoveries, citations to licensed patent-linked publications are higher in the three years after the license, although this difference is not statistically significant. We then disaggregate our sample into (a) patented discoveries that are likely to be used as “research tools” by other researchers (based on the presence of material transfer agreements (MTAs) that cover them) and (b) patented discoveries not covered by MTAs. Citations to publications linked to licensed patents in the latter subset (not covered by MTAs) are higher for publications linked to licensed patents, and this difference is statistically significant. In contrast, licensing of patented discoveries that are also research tools is associated with a reduction in citations to papers linked to these research advances, raising the possibility that licensing may restrict the flow of inputs to “follow-on” scientific research.  相似文献
