    Private higher education plays a vital role in its transition to a knowledge society. However, it is also facing a challenge to mitigate the local tension between access, equity, and quality. Recently, translanguaging as pedagogy has emerged in an emancipatory manner for teachers in English medium instruction contexts, like the Chinese private university, where the students are not able to perform in English-only classrooms. However, although pedagogical translanguaging in English reading is acknowledged by bilingual educators, we have little knowledge about the studentsā€™ attitudes toward it. Students are the real actors of translanguaging practices. Their attitudes and stances are decisive to their further application of this translanguaging approach. The study aims to explore Chinese private university studentsā€™ attitudes toward pedagogical translanguaging as a classroom norm in an English reading classroom. The data were collected through two debriefing interviews before and after translanguaging as intervention. A thematic analysis of the affordances and constraints was carried out to examine their perceptions about translanguaging. The findings showed that translanguaging practices among Chinese private university students have not been completely independent of monolingual ideology. Yet their appreciation of translanguaging informed the possibility of fortifying translanguaging awareness and thus establishing an ecological and democratic translanguaging classroom

    An Attitude Determination Method for Comprehensive Inspection Vehicle Based on Track Profile Registration

    The attitude of the comprehensive inspection vehicle is one of the important factors that affect the accuracy of the inspection of metro line infrastructure, meanwhile the metro environment restricts the employment of common attitude determination methods. A new method of attitude determination is presented in this paper, which takes the track as reference and employs non-contact measurement to acquire the track profile simulta-neously. By registration of measurement track profile and the standard track profile, the relative position between the vehicle and the track reference can be calculated; and the instantaneous attitude of the vehicle can be determined by the matrix inverse calculation. The performance of the method is verified by an experiment using the road-rail comprehensive inspection vehicle

    Functionalized carbonaceous materials with hierarchical structure and developed porosity are highly desired in energy storage and conversion fields. In this work, a facile and scalable hydrothermal methodology was established to synthesise three-dimensional (3D) N-doped carbonaceous aerogels using biomass-based starting materials and polypyrrole as N-source. The effect of different calcination temperatures on the structural properties, type and content of N-species and electrochemical performance of the 3D N-doped carbonaceous aerogels were uncovered. Thanks to the combinatorial effect of the appropriate N content and porous structure, the obtained samples exhibited excellent electrochemical performance, in particular, an outstanding specific capacitance of 281.0 F g-1 achieved on the sample calcined at 600 Ā°C. This methodology offers a new fabrication strategy to prepare nanoscale carbonaceous materials with desirable morphology and hierarchical architecture of great potentials for the applications in energy fields
