In this research notes, based on a setting of online reputation system, we demonstrate various issues related to using regression discontinuity design (RD) to do causal inference, meaning to study whether for a given vendor, an increase in its online reputation score causes, instead of being associated with, an increase on its online sales. In the e-commerce platform, sellers are typically assigned into different reputation levels based on their original continuous reputation scores, resulting in discontinuity in reputation and allowing a regression discontinuity (RD) design setting. Based on data from one of the largest crowdsource website in China, we find that given everything else be the same, on average, sellers with one extra reputation level improvement enjoys a 32.5% increase in their sales. The RD required manipulation test indicates that both the density of the sales and various other shop related attributes show no discontinuity. Falsification test also indicates that the impact of reputation on sales holds only at true threshold. Further cross-sectional analysis show that the effect is stronger for seller with relative low reputation, owned by individual person, without the platform VIP membership or vendors not participating in the consumer guarantee program. This is consistent with the argument that new and unknown sellers depends more on the reputation system to improve their sales, offering further corroboration to our results.

2018年正值中国改革开放40周年之际，为欧洲一体化进程奠定基础的《罗马条约》生效60周年之时，同时也是中欧建立全面战略伙伴关系15周年。为总结改革开放40年来中欧关系取得的成果，展望双方和平、增长、改革、文明伙伴关系在未来的前景和面临的挑战，深入探讨如何推动中国与欧洲在“新型大国关系”和“人类命运共同体”等理念的带动下，围绕“一带一路”倡议等设想，将双边合作提升至更高的层次，上海外国语大学、比利时欧洲学院与上海欧洲学会将于2018年10月29日举办“改革开放40周年的中国与欧洲——成就、挑战与前景”国际学术研讨会。

In this presentation, Professor Greenberg explores several theoretical perspectives on language policy and planning beginning with a framework on how language conflicts can be managed, and moving on to some of the sociolinguistic perspectiveson this topic. The theoretical perspectives are then applied to case studies from North America and Europe. Comparisons are made between language policies in the United States and Canada,and these are further contrasted with the policies being implemented in Europe. The presentation concludes with an analysis of the situation in the former Yugoslavia especially regarding matters of linguistic reciprocity across new national boundaries in the Balkan region.

上海外国语大学新闻传播学院“新文化”沙龙第7期
中国电影走向世界包括四个向度,即中国电影在西方主要电影节上获得承认;中国电影进入西方主流电影市场;中国电影赢得西方主流观众认可;中国电影不仅在西方也在东方得到传播。这一进程是政治原因、经济原因、文化原因和艺术原因复杂运作的结果。其中中国电影的西方电影节之旅或多或少是东方主义的后果,下一步则要超越东方主义。走向西方市场主要是个商业行为,但不限于通过院线,还可以通过电视台和互联网来传播。走向世界归根到底是要让西方观众接受,这需要中国电影学会用当代中国故事传达普世关怀。而在西方世界之外,中国还必须重视东方世界,在东方,中国既有便利性也面临东方被文化殖民的新的困难。作为负责任的大国,中国电影的走出去更多地是在承担一份文化责任,而不是单纯的商业行为 。

This talk will focus on current issues in qualitative research methods, addressing some of the methodological challenges that qualitative researchers face and highlighting opportunities for exploring new avenues and exploiting opportunities offered by technological developments. The talk will cover the following topics:

· Engaging with ongoing challenges: The research interview; saturation
· Embracing new opportunities: Mixed methods; interdisciplinarity
· Entertaining radical ideas: Replication
· Exploiting new resources: Big Data and technological tools
· Exploring new dimensions: New forms of collaboration (IDLab, VEO)
· Expanding horizons: A global perspective

A handout accompanying the talk will include a select annotated bibliography of key papers (available online) related to the topics. It will also include links to two important recently developed analytical resources.
