Overworked and stressed teachers under market economy: Case Study in Northwest China

This chapter is based on a case study conducted in Xisheng (pseudonym promised to the participants for anonymity purposes) in Northwest China to explore teachers’ perspectives on teaching under the market economy system. The original plan was to study local indigenous teachers, but that was not possible due to political sensitivity of the region at the time of data collection. As a result, we interviewed mostly Han teachers, including as many local indigenous teachers as possible. We think that the study is still useful as it was the first study of its kind and that it was informative regarding the impact of the market economy on teachers in northwestern China. Some findings of the study were discussed in Beckett (2012) and Guo et al. (2013). In this chapter, we refer to that work and discuss additional data that were not discussed in those publications. The remainder of the chapter discusses ideological and sociocultural contexts and research methods of the study followed by findings and discussions. We conclude with limitations and implications of the study

White dwarf-main sequence binaries from LAMOST: the DR1 catalogue

Context. White dwarf-main sequence (WDMS) binaries are used to study several different important open problems in modern astrophysics. Aims. The Sloan Digital Sky Survey (SDSS) identified the largest catalogue of WDMS binaries currently known. However, this sample is seriously affected by selection effects and the population of systems containing cool white dwarfs and early-type companions is under-represented.Here we search for WDMS binaries within the spectroscopic data release 1 of the LAMOST (Large sky Area Multi-Object fiber Spectroscopic Telescope) survey. LAMOST and SDSS follow different target selection algorithms. Hence, LAMOST WDMS binaries may be drawn from a different parent population and thus help in overcoming the selection effects incorporated by SDSS on the current observed population. Methods. We develop a fast and efficient routine based on the wavelet transform to identify LAMOST WDMS binaries containing a DA white dwarf and a M dwarf companion, and apply a decomposition/fitting routine to their LAMOST spectra to estimate their distances and measure their stellar parameters, namely the white dwarf effective temperatures, surface gravities and masses, and the secondary star spectral types. Results. We identify 121 LAMOST WDMS binaries, 80 of which are new discoveries, and estimate the sample to be \sim90 per cent complete. The LAMOST and SDSS WDMS binaries are found to be statistically different. However, this result is not due to the different target selection criteria of both surveys, but likely a simple consequence of the different observing conditions. Thus, the LAMOST population is found at considerably shorter distances (\sim50-450 pc) and is dominated by systems containing early-type companions and hot white dwarfs.

Tweeting as a Marketing Tool: A Field Experiment in the TV Industry

© 2017, American Marketing Association. Many businesses today have adopted tweeting as a new form of product marketing. However, whether and how tweeting affects product demand remains inconclusive. The authors explore this question using a randomized field experiment on Sina Weibo, the top tweeting website in China. The authors collaborate with a major global media company and examine how the viewing of its TV shows is affected by (1) the media company's tweets about its shows, and (2) recruited Weibo influentials' retweets of the company tweets. The authors find that both company tweets and influential retweets increase show viewing, but in different ways. Company tweets directly boost viewing, whereas influential retweets increase viewing if the show tweet is informative. Meanwhile, influential retweets are more effective than company tweets in bringing new Weibo followers to the company, which indirectly increases viewing. The authors discuss recommendations on how to manage tweeting as a marketing tool.National Natural Science Foundation of China (No. 71372045)National Natural Science Foundation of China (No. 71602033

Pathway towards sustainability or motorization?:A comparative study of e-bikes in China and the Netherlands

Faced with globally pressing sustainability challenges, the e-bike provides a potentially sustainable mobility alternative. Yet, a growing consensus among researchers is that the environmental and social impacts of e-bikes are context dependent. Previous studies indicate different e-bike pathways in two major e-bike markets. In China, e-bikes seem to be a stepping stone to further motorization. In the Netherlands, e-bike use partially substitutes car use, thereby advancing sustainability. However, little is known about why e-bikes serve different pathways. We address this research problem by employing social practice theory to unpack e-bike practices according to three interdependent elements of materials, competences, and meanings. In doing so, we shed light on the more complex and nuanced dynamics in everyday mobility practices around e-bikes. The findings suggest that in China hostile cycling conditions and positive cultural associations of automobility feed to a vicious circle toward car-based motorization. In the Netherlands, the e-bike provides a viable option for those locked into car practices. Despite these differences, evidence from the two countries indicates that dissatisfactions with elements of car practices may redirect people to e-bike practices. Policy needs to direct toward overcoming structural barriers in domains where individuals have limited agency. Furthermore, this comparative study illustrates that differentiated focus is needed when applying practice theory. Given that the average carbon footprint per capita is lower in the Global South than in the Global North, the focus should be on maintaining existing sustainable practices in the Global South while substituting unsustainable practices in the Global North

Based on the Integration of “Internet + Ideology and Politics”, the Practice of Online and Offline Mixed Teaching Mode of Modern Medical Courses in Traditional Chinese Medicine Majors

The purpose of this paper is to explore how to implement the online and offline mixed teaching mode in the modern medical courses of TCM specialty under the guidance of the concept of “Internet + ideological and political integration”, and to explore its practical experience and remarkable results. With the power of today’s Internet technology, we will organically integrate ideological and political education into the modern medicine course of traditional Chinese medicine, so as to effectively promote the overall cultivation of students’ comprehensive quality, and further enhance the attraction of the course and educational benefits

A Search for Spectral Galaxy Pairs of Overlapping Galaxies based on Fuzzy Recognition

The Spectral Galaxy Pairs (SGPs) are defined as the composite galaxy spectra which contain two independent redshift systems. These spectra are useful for studying dust properties of the foreground galaxies. In this paper, a total of 165 spectra of SGPs are mined out from Sloan Digital Sky Survey (SDSS) Data Release 9 (DR9) using the concept of membership degree from the fuzzy set theory particularly defined to be suitable for fuzzily identifying emission lines. The spectra and images of this sample are classified according to the membership degree and their image features, respectively. Many of these 2nd redshift systems are too small or too dim to select from the SDSS images alone, making the sample a potentially unique source of information on dust effects in low-luminosity or low-surface-brightness galaxies that are underrepresented in morphological pair samples. The dust extinction of the objects with high membership degree is also estimated by Balmer decrement. Additionally, analyses for a series of spectroscopic observations of one SGP from 165 systems indicate that a newly star-forming region of our Milky Way might occur.Comment: 16pages, 6figure
