Language use and communicative behaviors are important indicators of sojourners' adjustment. The current research was conducted to understand international students' communication behavior on Facebook during their adjustment period in the US and its relationship to the students' acculturative attitude (identification with heritage and mainstream culture), current psychological adjustment level, socio-cultural adaptation level, and target audience on Facebook. Two main theories provided the theoretical framework of the study: Giles' communication accommodation theory (1973) and Berry's acculturation model (1984). Snowball and convenience samples were used to recruit 178 international students from different universities across the US. A mixed approach of online survey and content analysis was used to test the hypotheses and research questions. The results showed that during the stay in the US, international students accommodate their language and topic choice towards their American peers on Facebook. Particularly, it was found that language accommodation levels increase as the students' length of stay in the US increases. The results also demonstrate that international students use Facebook mainly to communicate with friends who reside in the US. When students had higher levels of mainstream identification, they were likely to target American friends as their audience on Facebook and thus have more language and topic accommodation. Additionally, acculturation attitude (heritage and mainstream identification) predicted the students' language accommodation level. Lastly, the study showed that there is a positive relationship between language accommodation and sociocultural adjustment. The findings of the study not only expand the scope of communication accommodation theory and acculturation model, but also enhance understanding of international students' online communication patterns, their purposes, and practical consequences upon their adjustment in the US. This is important because it can be useful in finding ways to improve the students' experience in the US.

This dissertation examined the relationship between language diversity and the implementation of on-the-job training programs. Using India as the empirical context, I conducted a multi-case study research, which involved semi-structured interviews and direct observations in the headquarters of two Indian multinational enterprises. Drawing from social identity theory, I first examined the factors that influence the emergence and transformation of two types of language -based clusters, coping clusters and clusters of convenience. The two types of clusters display distinct mechanisms related to arousal, ingroup favoritism and outgroup bias, which questions one of the key assumptions of social identity theory related to the role of affect. Additionally, I found that language diversity can create cognitive discomfort for training recipients, and emotional anxiety for both training facilitators and recipients. However, training recipients, training facilitators, and the executive management, (i.e., the firm) can utilize certain language accommodation approaches that can reduce the emotional and cognitive discomfort experienced by employees. Using communication accommodation theory, I discuss that the influence of each language accommodation approach depends on its source and time of implementation. As well, language -based clusters can facilitate the exchange of interpersonal information during on-the-job training programs. The emergent findings also suggest that linguistic identity seldom operates in isolation. It often intersects with other dimensions of social identity, specifically, the status differentials attached to gender, education and regional dialects. The findings have implications for research on language diversity and language management in international business, social identity theory and communication accommodation theory. / Graduate / 2022-08-22

The thesis covers sociolinguistic and psycholinguistic aspects of Czech and Slovak language relations. To both fields, it contributes in the form of own empirical research. At the centre of attention are native speakers of Slovak living long-term in Czechia and their language behaviour under this setting in relation to Czech and Slovak. Given that two languages in question are genetically very close and mutual intelligible, the actual language behaviour of the described population is not strictly predetermined by the social norms (Dickins, 2009). However, there are also conditions supporting the accommodation to Czech (Sloboda, 2005). The thesis focuses on the identification of factors influencing language choice and on the impacts of such factors on the psychlinguistic processing of Slovak and Czech words. The sociolinguistic part builds on questionnaire-based surveys, such as those conducted by Sloboda (2006). The own questionnaire survey was carried out via web. The data from 651 respondents were assessed, all from native speakers of Slovak having grown up in Slovakia and commencing their stay in Czechia after the age of 18. The data revealed that Slovak is used more than Czech, that Czech is more often perceived, that the use of Czech is more common in the communication with strangers or in...
