How can we talk about China and against Sinophobia without feeling guilty, apologetic or defensive?

Drawing on our experience as early career researchers who identify as Chinese, we discuss how such an identity has inevitably and unjustifiably come to entrap us in the politics of the great power rivalries of our time. We call for attention to the discrimination against Chinese scholars in the process of academic knowledge production, in particular, in peer review processes.Publisher PDFNon peer reviewe

IS Per Capita Real GDP Stationary in China¡H Evidence Based on A Panel SURADF Approach

In this study we use newly developed Panel SURADF tests of the Breuer et al., (2001) to investigate the time-series properties of 25 Chinese provinces¡¦ per capita real GDP for the 1952-1998 period. While the other Panel-based unit root tests are joint tests of a unit root for all members of the panel and are incapable of determining the mix of I(0) and I(1) series in the panel setting, the Panel SURADF tests a separate unit-root null hypothesis for each individual panel member and, therefore identifies how many and which series in the panel are stationary processes. The empirical results indicate that for all the provinces studied per capita real GDP are non-stationary, except Hebei, Jeilongjiang, Qinghai and Shaanxi when Breuer et al.¡¦s (2001) Panel SURADF tests are conducted.Per Capita Real GDP Panel Unit Root Tests

Learning-by-Teaching in CS Education: A Systematic Review

To investigate the strategies and approaches in teaching Computer Science (CS), we searched the literature review in CS education in the past ten years. The reviews show that learning-by-teaching with the use of technologies is helpful for improving student learning. To further investigate the strategies that are applied to learning-by-teaching, three categories are identified: peer tutoring, game-based flipped classroom, and teachable agents. In each category, we further searched and investigated prior studies. The results reveal the effectiveness and challenges of each strategy and provide insights for future studies

How Much Can VR Improve Spatial Experience? - A Case Study with a Commercial Building Project

With the development of Industry 4.0 and the impact of the COVID-19 epidemic, the global construction industry has undergone a rapid digital transformation, pushing the development of building information modeling (BIM), virtual reality (VR), augmented reality (AR) and mixed reality (MR) technologies towards greater maturity. However, from the perspective of building developers and end users, does VR technology have any benefit for complex building projects? What are users' acceptance and evaluation on VR emerging technology? After constructing a VR simulation navigation system for an actual commercial building project, this study investigated and compared the differences between using the VR system and the traditional navigation system in the four dimensions of the technology acceptance model. The results showed that the subjects generally believed that the VR system has significant benefits in terms of usefulness, users’ attitude, and users’ intention, however, there is still room for improvement in the perceived ease of use. Moreover, feedback from developers supported the benefits of the VR technology validated the system effectiveness. Hence, VR and BIM technologies are recommended to be effectively integrated, in order to enhance the integrity of industrial applications and establish a new design communication and collaboration model for the architecture, engineering, construction, and facility management industry

Modeling mutual feedback between users and recommender systems

Recommender systems daily influence our decisions on the Internet. While considerable attention has been given to issues such as recommendation accuracy and user privacy, the long-term mutual feedback between a recommender system and the decisions of its users has been neglected so far. We propose here a model of network evolution which allows us to study the complex dynamics induced by this feedback, including the hysteresis effect which is typical for systems with non-linear dynamics. Despite the popular belief that recommendation helps users to discover new things, we find that the long-term use of recommendation can contribute to the rise of extremely popular items and thus ultimately narrow the user choice. These results are supported by measurements of the time evolution of item popularity inequality in real systems. We show that this adverse effect of recommendation can be tamed by sacrificing part of short-term recommendation accuracy
