On the social-cultural changes of English and Chinese words from ＂jiayou＂

Word is the most active factor in the research of culture connotations and it is essential in understanding the culture of target language. This article not only attempts to analyze non-equivalence in semantic and cultural connotation of words between Chinese and English words from cross-cultural perspective, but also highlights the profound understanding of the relation of culture, and language is the best way to avoid cross-cultural barriers and obstacles. Finally, by elaborating the loan words between two different cultures, the paper maintains the cultural integration out of respect, appreciation and acceptance is the embodiment of human social and cultural development of human society and the vitality of the cultural changes.

Incommensurability in Second Language Acquisition Approaches

Researchers in the field of Second Language Acquisition （SLA） have been taking different routes. Some researchers make linguistic-cognitive issues their inquire object and pursue objectivity with quantitative research methods. Other researchers regard the social context of activity as an essential characteristic of learning and teaching. These groups of researchers make use of qualitative research methods like case study, grounded theory, narrative inquiry, and ethnography. There are many other routes that SLA researchers have taken, but the two just mentioned are perhaps the most predominant ones and the ones that are most easily contrasted. The present paper explores the disparity between the different research paths from the perspective of philosophy of science echoing the notion of incommensurability. In this paper the author argues that the differences between different SLA perspectives are not only commensurable but wholesome for the development of SLA.

Factors of heavy social media use among 13-year-old adolescents on weekdays and weekends

Background Few studies have investigated which factors were related to adolescents'social media use.This study aimed to evaluate which factors were associated with heavy social media use on weekdays and weekends among 13-year-old adolescents.Methods We analyzed data from 3727 children from the Generation R Study,a population-based cohort study in the Neth-erlands.Associations of demographic factors(child age,sex,ethnic background,and family situation),socioeconomic posi-tion(parental educational level,parental employment status,and net household income),screen-based behaviors(computer playing and TV viewing),and the home environment(communication,supervision,and restriction)with adolescents'heavy social media use(≥2 hours/day)were assessed separately on weekdays and weekends.Multivariate logistic regression analysis was applied.Results The prevalence of heavy social media use was 37.7%on a weekday and 59.6%on a weekend day.Being a girl,liv-ing in a one-parent family,and more time spent playing on the computer were associated with heavy social media use on weekdays and weekends(all P<0.05).Low socioeconomic position adolescents(low parental educational level and low household income)were more likely to show heavy social media use only on weekends(all P<0.05).Children whose social media use was restricted by parents on weekdays or children whose social media use was supervised by parents on weekends had lower odds of heavy social media use(all P<0.05).Conclusions Being a girl,living in a one-parent family,or having a longer computer playing time were associated with heavy social media use on weekdays and weekends.More studies are needed to understand the factors associated with heavy social media use and the impact of heavy social media use on child health.

Perspective:Societally connected multimedia across cultures

The advance of the Internet in the past decade has radically changed the way people communicate and col- laborate with each other. Physical distance is no more a barrier in online social networks, but cultural differences （at the individual, community, as well as societal levels） still govern human-human interactions and must be con- sidered and leveraged in the online world. The rapid deployment of high-speed lnternet allows humans to interact using a rich set of multimedia data such as texts, pictures, and videos. This position paper proposes to define a new research area called ＇connected multimedia＇, which is the study of a collection of research issues of the super-area social media that receive little attention in the literature. By connected multimedia, we mean the study of the social and technical interactions among users, multimedia data, and devices across cultures and explicitly exploiting the cultural differences. We justify why it is necessary to bring attention to this new research area and what benefits of this new research area may bring to the broader scientific research community and the humanity.
