A Review of Literature on Social Media and Acculturation

With the development of populous mobility and digital technology, integration of acculturation and social media, which is represented by Social Networking Sites (SNSs), is increasingly focused on by academia. With the keyword selection, 34 articles were collected. The structured content analysis was adopted to conduct the review via mapping, assessing, and synthesizing the articles. It was found that acculturation and related topics are closely related to social media. Specifically, the integration of SNSs and acculturation is the trend of present and future research. The research gaps based on the literature are also proposed for future studies.


Introduction
With the development of globalization, it has been commonplace for people to sojourn abroad for purposes of work or study. The sojourners include immigrants, expatriates, refugees, international students, etc., according to classification in general. Researches (Geeraert & Demoulin, 2013) show that, as with other forms of international mobility, the process of acculturating into the new environment is essential for working or studying abroad. When exposure to a foreign country, interacting and getting contact with another culture frequently over time, acculturation arises (Berry & Sabatier, 2011). Acculturation has been a sustainable object for international studies in the field of sociology, psychology, and management, etc. It has been estimated that there are currently 50 million expatriates and include more than 5 million international students worldwide (ICEF Monitor, 2017). In 2030, it is estimated by Study portals that there will be How to cite this paper: Wen, K. K. (2020). A Review of Literature on Social Media and Acculturation. Open Journal of Social Sciences,8,[19][20][21][22][23][24][25][26][27][28][29] 51% more students studying in higher education institutions outside their own countries than that in 2015 (so an additional 2.3 million students to total 6.9 million tertiary students abroad in 2030) (ICEF Monitor, 2019). It is natural and inescapable for sojourners in host cultures. Therefore, it deserves studying this prevalent international phenomenon, in which acculturation is one of the most significant parts.
With the advances of digital information and web technologies, especially 4G technology, it has dramatically boosted the development and application of social media platforms represented by Social Networking Sites (Afterwards SNSs) in a big scope of fields. After the 2010s, social media, especially SNSs has been broadly used in practice. Easier access to the Internet and increasing multiple demands facilitated the formation of online communities in social media, which fostered the emergence of the online cultures with their corresponding behavior and language practices (Mitra & Evansluong, 2019). Using Social media platforms, especially SNSs to stay connected to family, friends, and other online users is considered as an important part of many individuals' daily life when they are exposed to new cultures (Eslami & Yang, 2018). Some popular SNSs, such as Myspace, Twitter, Weibo, WeChat, and Facebook, attract numerous users of different nationalities. Maintaining relationships with family and friends, communicating thoughts and activities, and meeting new individuals are primary functions of SNSs. As of March 2017, there were over 1.94 billion monthly-active, Facebook users (Facebook MAUs), which is an 18% increase, year over year (Facebook 5/3/17).

Acculturation and Social Media
Acculturation refers to "those phenomena which result in when groups of individuals having different cultures come into continuous first-hand contact, with subsequent changes in the original cultural pattern of either or both groups " (R. Redfield, R. Linton, and M. Herskovits, 1936). It is possibly the earliest definition of acculturation (Tranfield, Denyer, & Smart, 2003). They described acculturation as a process that occurs when groups of different cultures brought together in contact and which consequently leads to changes in the cultural patterns. Although acculturation is a neutral term in principle (that is, change may take place in either or both groups), acculturation in practice tends to induce more change in one of the groups than in the other (Berry & Sabatier, 2011).
Social media, especially SNSs, as online services to build social relations among people who communicate with each other, have rapidly become a global consumer phenomenon (Huang, Hsieh, & Wu, 2014). Several popular SNSs, such as Facebook, Snap Chat, Twitter, Kaokao Talk in Korea, and WeChat in China, are widely used among teenagers and young adults, as they provide an open platform for these individuals to communicate, produce and exchange information such as pictures, videos, interests, and preferences (Milosevic-Dordevic & Žeželj, 2014 We need to conduct a systematic literature review research by addressing the following research questions: RQ1. What is the status quo of the research on the integration of acculturation and social media or SNSs?
RQ2. What is the relationship between acculturation and social media or SNSs in present research?
To answer the above two research questions, we conducted a systematic literature review focused on acculturation and social media or SNSs in the present literature. Systematic literature reviews are appropriate for mapping, assessing, and synthesizing different pieces of literature to develop the knowledge base in a field (Tranfield et al., 2003). Therefore, the literature review article was selected to research the following sections.

Methodology
This article aims to analyze the relationships between acculturation and social media especially SNSs and investigate the status quo of the research on this topic systematically, and more importantly to identify the research gap for future studies. We accomplish this aim by conducting a systematic literature review based on structured content analysis. Tranfield et al. (2003) argue that there are two goals for literature reviewing: to consolidate research findings in a specific field by mapping, assessing and synthesizing different pieces of literature and identifying research gaps for future studies. Evidence is important in the literature review considering it supports the collection and analysis of materials to reach transparent and reliable outcomes. To further elaborate on our literature review, we apply structured content analysis as suggested by some scholars (Seuring & Gold, 2012). Structured content analysis is a commonly adopted method for systematically assessing the themes of recorded communication. It is employed for conducting literature reviews because it provides a sound understanding of the focus of written text in a rule-governed manner, thus replicability can be accomplished as well (Seuring & Gold, 2012).
According to Seuring and Gold (2012), a four-step process for conducting literature reviews based on structured content analysis is reasonable. The four steps include material collection, descriptive analysis, category identification, and material evaluation. The following sections will follow the four steps. After searching the literature, the multi-sectional analysis was employed to analyze. A variety of figures, charts, and tables were used to illustrate the contrasts and comparisons so that the outcomes can show clearly.

Results
Through the database ScienceDirect and Scopus, combined with sorting of ABDC journal ranking, with putting the keyword "acculturation", "cross-cultural adaption", "inter-cultural adaption", plus "social media" "social networking sites/services" "SNSs" in English, totally 34 peer-reviewed English articles were found in titles including the said keywords. To analyze and conclude these articles were downloaded and categorized according to different norms and catenaries, such as the year published, focused areas, geographic focus, the method adopted, etc., some figures and graphs were produced automatically with the help of Excel and relevant statistical software.
There are not many articles relevant to acculturation and social media or SNSs. One possible reason may be that social media, especially SNSs is a newly emerged thing, started from the 2010s, just as stated in the introduction part. It has a process for sojourners to use; then it also takes time for academics to study the phenomenon.
Exactly, as Figure  As for geographic location, it is imbalanced. As Figure 2 shows, USA is the most intensively studied geographic country with 16 articles focused, accounting for 47%; other focused countries include China with 6 articles, Republic Korea, Netherlands, UK, Malaysia, Japan and Australia followed in sequence of degree of studied density.
As we consider the years on which the researches were focused, we can find,      articles are related to SNSs as their either independent variable or dependent variable.
The theories employed are varied, which was indicated in line with the key-dependent variables, independent variables, authors of the articles, years in Table 1. We can find that Berry's acculturation theory is the most popular theory, which was adopted in 13 articles, followed by Hofstede's' collectivism vs individualism in 3 articles. We also find that among key dependent variables, acculturation is the most common one; while among key independent variables, that is SNSs, followed by social media. From

Conclusion
We can conclude from the above sections by systematically mapping, collecting, analyzing, and synthesizing the mentioned literature (Koberg & Longoni, 2019).
For the different numbers of articles published in different years, one of the possible causes for the dramatic increase of the articles published in 2019 is that the research on the integration of acculturation and social media especially SNSs is still hot and popular, though it is a new research topic recently (Hofhuis et al., 2019). Also, deduced from Figure 2 and Figure 6, the number of international students has been surging since the new century, and some countries in North America, west Europe, East Asia have been or are becoming the major destinations of international students' mobility. Therefore, it is likely that their acculturation and related issues give rise to academics' attention and interests. One phenomenon that a curve exists in the period from 2015 to 2019 was not delivered a reasonable explanation until now. Deducing from Figure 3, the dramatic changes of years focused, the possible reason for some year was focused that may be interpreted that some factors, such as new technologies, political policies, affect the changes.
Regarding the distribution of geography, we judge that one cause for the unbalanced distribution of geographic focus of the research may be that the USA is a traditional and ongoing destination of population mobility, especially for international students. Moreover, the USA and China are the original and emerging centers of digital technology, where most IT giants such as Facebook, Twitter, WeChat, and Tiktok are located. Therefore, SNSs and other social media platforms are prevalent in these areas (Hofhuis et al., 2019).
The methodology is unambiguous in the mentioned literature. In terms of acculturation and social media or SNSs, a measurement that can be accomplished is one of the reasons that the quantitative method is mostly employed in the research. Also, there have been some available Metrix, scales, and questionnaires which were developed by some scholars and were verified to be reliable and valid in the field of acculturation and diffusion of social media. Considering the integration with technology, Technological Forecasting & Social Change was the preferred journal for this study and its researchers.
International students have been a major temporary sojourner with the rapid development of globalization of economy, technology, and talent. And the international students are vulnerable to acculturation, more stressed; therefore, they may be focused by academia more than other sojourner groups. One more possible reason is that international students are more active and professional in using social media and SNSs; moreover, it is necessary for them to communicate with their parents, friends, and others to buffer their acculturative stress (Yu, Foroudi, & Gupta, 2019). Compared with other traditional social media, such as newspapers and TV, SNSs are becoming more and more popular for its multiple strengths as mentioned in the introduction part.
In terms of theories employed in literature, Berry's acculturation theory is the

Discussion and Implications for Future Research
There are some implications. The mentioned articles were all published recently, which implies the trend of the research in the area to some degree. From the figures, charts, and tables, as well as the above sections, we can foresee the following contents and perspectives may be the trends and hot subtopics in future research. It is predicted that in future the research on the integration of acculturation and SNSs, and other related topics will still be the interests of academia in this field, considering the gap that the status quo is and how it works regarding the integration of acculturation and SNSs in other countries, especially in developing countries. One more reason is that with the rapid economic development, developing countries are increasingly focusing on the development and application of digital information.
I am aware that the research has some limitations. Just as many literature reviewing papers, a keyword search was adopted for the review, which may affect and limit the results owing to combinations of keywords. A second limitation is the researcher's biases when the author selects current relevant articles. A third limitation is that there is only one author who may arouse some mistakes or neglects, and even bias. Subjectivity is another limitation for the research considering the method structured content analysis used and the criteria for the article were set subjectively, without former studies. Also, only peer-reviewed papers are selected without considering other sources such as conference papers, Ph.D. degree thesis, and industrial reports. Finally, in the topic integration of acculturation and social media or SNSs, three keywords are all broad with many different definitions, demarcations, and categories, therefore the research may not be accurate to some extent. Nonetheless, we still believe this review makes some contributions to the knowledge of acculturation and its integration with related digital technology.
Broadly speaking, the research is a cross-disciplinary study related to technology, sociology, psychology, culture, and management. Therefore, in the future, it is suggested editors of relevant journals related to be said disciplinaries can consider accepting more articles concerning the integration of acculturation and social media or SNSs. Also, more qualitative and mixed methods are suggested to adopt to supplement and enrich the research from the disparate lens of research. Besides, maybe more attention should be concentrated on other less populous sojourners, such as migrants, refugees, and tourists. The number of these sojourners is also growing fast these years, especially international tourists.
Finally, the researchers may focus on more SNSs' roles and effects on acculturation and related topics in that SNSs is ongoing, full of more imagination and
