A Case Study of Choices of the Host University and Decisions to Stay or Leave the U.S. upon Graduation of Chinese Adult and Traditional Students
Chinese students are the largest group among all the international students. Many factors motivate them to study in the U.S. and their decision to stay or leave the U.S. after graduation. However, limited research investigates these aspects by differentiating students into non-traditional students and traditional student groups. As a result, this study conducted individual interviews to examine: 1) factors that influence Chinese students’ (non-traditional students vs. traditional students) choices of the host college or university in the U.S.; and 2) their decisions to stay or leave the U.S. after graduation. Eleven Chinese students participated in this study, including seven female students and four male students. Their ages range from 23 to 30 years old with the mean of 25.8. They are from majors across STEM and non-STEM fields. Among them, four had working experience who are considered as non-traditional students, while the rest are traditional students. Findings show that Chinese non-traditional students consider financial aid availability most when choosing the college abroad, while traditional students focused on the ranks of academic programs or colleges. In addition, most Chinese non-traditional students preferred to return to their home country. However, most traditional students would choose to remain in the U.S. after graduation. Meanwhile, most students desired to have some working experience in the U.S. It is hoped that this study would lead to a greater awareness of Chinese international students and enlighten higher education professionals and administrators with practical ideas to build a better campus environment and climate to serve this growing population
Generation of Optical Chirality Patterns with Plane Waves, Evanescent Waves and Surface Plasmon Waves
We systematically investigate the generation of optical chirality patterns by
applying the superposition of two waves in three scenarios, namely plane waves
in free space, evanescent waves of totally reflected light at dielectric
interface and propagating surface plasmon waves on a metallic surface. In each
scenario, the general analytical solution of the optical chirality pattern is
derived for different polarization states and propagating directions of the two
waves. The analytical solutions are verified by numerical simulations.
Spatially structured optical chirality patterns can be generated in all
scenarios if the incident polarization states and propagation directions are
correctly chosen. Optical chirality enhancement can be obtained from the
constructive interference of free-space circularly polarized light or enhanced
evanescent waves of totally reflected light. Surface plasmon waves do not
provide enhanced optical chirality unless the near-field intensity enhancement
is sufficiently high. The structured optical chirality patterns may find
applications in chirality sorting, chiral imaging and circular dichroism

Distributed tracking control of leader-follower multi-agent systems under noisy measurement
In this paper, a distributed tracking control scheme with distributed
estimators has been developed for a leader-follower multi-agent system with
measurement noises and directed interconnection topology. It is supposed that
each follower can only measure relative positions of its neighbors in a noisy
environment, including the relative position of the second-order active leader.
A neighbor-based tracking protocol together with distributed estimators is
designed based on a novel velocity decomposition technique. It is shown that
the closed loop tracking control system is stochastically stable in mean square
and the estimation errors converge to zero in mean square as well. A simulation
example is finally given to illustrate the performance of the proposed control
scheme.Comment: 8 Pages, 3 figure
Mutual Help or Social Responsibility of Higher Education—A CJCU Experience
In 2009, Typhoon Morakot caused severe damage to the mountains in Kaohsiung, Taiwan. Laulong was one of the villages affected by the typhoon. While all the communities have made all the efforts to restore their infrastructure and livelihood, Laulong village has its unique mission to restore the history and culture of their own. The residents there identify themselves as “Tavorang Tribe”, whose ancestors were from other areas. After merging with other people, they are gradually losing their tribal language. They have come to realize that their traditional rituals and tribal history are at risk of extinction; thus, they have endeavored to preserve and reconstruct their heritage. Chang Jung Christian University (CJCU) has involved in reviving these areas after Morakot. The Department of Applied Philosophy targets at this community as the educational field. The way to flip educational field requires taking students into the society. The purpose of this paper is to share the teaching experience of the past and students’ learning outcomes. It will introduce how a university tried to utilize resource from the government to work with a community while claiming to fulfill its social responsibility, but in fact, both actually received mutual benefits by executing this project
Outlier-Resilient Web Service QoS Prediction
The proliferation of Web services makes it difficult for users to select the
most appropriate one among numerous functionally identical or similar service
candidates. Quality-of-Service (QoS) describes the non-functional
characteristics of Web services, and it has become the key differentiator for
service selection. However, users cannot invoke all Web services to obtain the
corresponding QoS values due to high time cost and huge resource overhead.
Thus, it is essential to predict unknown QoS values. Although various QoS
prediction methods have been proposed, few of them have taken outliers into
consideration, which may dramatically degrade the prediction performance. To
overcome this limitation, we propose an outlier-resilient QoS prediction method
in this paper. Our method utilizes Cauchy loss to measure the discrepancy
between the observed QoS values and the predicted ones. Owing to the robustness
of Cauchy loss, our method is resilient to outliers. We further extend our
method to provide time-aware QoS prediction results by taking the temporal
information into consideration. Finally, we conduct extensive experiments on
both static and dynamic datasets. The results demonstrate that our method is
able to achieve better performance than state-of-the-art baseline methods.Comment: 12 pages, to appear at the Web Conference (WWW) 202
