Language ideologies and English in Chinese primary education
No full textEnglish education has been promoted widely in China and has driven scholarly attention to young Chinese learners of English. However, not much has been done to address language ideologies embedded in English education oriented towards young Chinese learners from a perspective informed by the research on the global spread of English as a lingua franca (ELF). To narrow the gap, we adopt an ELF perspective to investigate textbook representations and teacher perceptions of English in relation to culture and identity in Chinese primary education. The findings demonstrate a Standard English ideology and an essentialist approach to language. We thus argue for a reconsideration of ‘English’ in primary education in order to empower young generations of English learners in China. While English is an essential language for international engagement, it is necessary to reconsider the relationship between English and China and to review the ownership of English

Structure and Psychological Test Information

Abstract
The main purpose of this study was to locate what an occupational information structure should looks like, and what information should be included. So that we can find a working framework to build up occupational information database. In the mean time, this study also tried to find out the useful information of frequently used psychological tests in career counseling to discuss the possibilities of the connection between test results and occupational information. As far as the research methodology, the researcher collected four electronic occupation information database in Taiwanese Web. The 44 occupation samples which meet the condition of being in three of the four databases were chosen. The researcher analyzed the description of all the 44 occupation samples, abstracted the occupational information the data what to tell and found out the possible data structure. Besides, the researcher used the norms of these 44 occupation samples in ‘Vocational Interest Scale’, ‘Career Interest Scale’, ‘General Aptitude Test Battery’ and ‘Work Temperature Test’ to discuss the occupational information inside. The first result shows that the proposed structure contains rich occupation information, and the structure also includes both ‘occupation information’ and ‘people information’ in the consideration of occupational decision making. The other result discovers that psychological tests provide much information about occupation but these information wasn’t fully used in describing people’s psychological attributes in terms of occupation description.
At last, based on the results, discussions of how to build up an occupation database, the development of psychological tests for occupational use and further research are proposed as well.
Axisymmetric polydimethysiloxane microchannels for in vitro hemodynamic studies
No full textThe current microdevices used for biomedical research are often manufactured using microelectromechanical systems (MEMS) technology. Although it is possible to fabricate precise and reproducible rectangular microchannels using soft lithography techniques, this kind of geometry may not reflect the actual physiology of the microcirculation. Here, we present a simple method to fabricate circular polydimethysiloxane (PDMS) microchannels aiming to mimic an in vivo microvascular environment and suitable for state-of-the-art microscale flow visualization techniques, such as confocal µPIV/PTV. By using a confocal µPTV system individual red blood cells (RBCs) were successfully tracked trough a 75 µm circular PDMS microchannel. The results show that RBC lateral dispersion increases with the volume fraction of RBCs in the solution, i.e. with the hematocrit
Dioxygen Oxidation Cu(II)→Cu(III) in the CopperComplex of cyclo(Lys-DHis-βAla-His): a Case Study byEXAFS and XANES Approach
Full text linkA former spectroscopic study of Cu(II) coordination by the 13-membered ring cyclic tetrapeptide c(Lys-DHis-βAla-His) (DK13), revealed the presence, at alkaline pH, of a stable
peptide/Cu(III) complex formed in solution by atmospheric dioxygen oxidation. To understand the nature of this coordination compound and to investigate the role of the His residues in the Cu(III) species formation, Cu K-edge XANES and EXAFS spectra have been collected for DK13 and two other 13-membered cyclo-peptides: the diastereoisomer c(Lys-His-βAla-His) (LK13), and c(Gly-βAla-Gly-Lys) (GK13), devoid of His residues. Comparison of pre-edge peak features with those of Cu model compounds, allowed to determine the Cu oxidation state in the three peptides: DK13 contains only Cu(III) ions in the experimental conditions, while GK13 binds only with Cu(II) and LK13 gives a mixture of Cu(II) and Cu(III) coordinated species. Theoretical XANES spectra have been calculated by means of the MXAN code. The good agreement between theoretical and experimental XANES data collected for DK13, suggests that the refined structure, at least in the first coordination shell around Cu,
is a good approximation of the DK13/Cu(III) coordination species present at strongly alkaline pH. All the data are consistent with a slightly distorted pyramidal CuN4 unit, coming from the peptide bonds.
Surprisingly, the His side-chains seemed not involved in the final, stable, Cu(III) scaffold
