Peripheral Ritualized Practices—Threads Connecting Decorations to the Cloak of Identity     

《Journal of Intercultural Communication Research》2013,42(1):44-63

This is an ethnographic study which investigates the practices of language maintenance and ethnic identity affiliation for immigrant/migrant Nepalese families with primary to middle school children in the United Kingdom. The study presents a comparative case study analysis of three Nepalese immigrant/migrant families. Participant observation, semi-structured interviews, and historical narrative interview were used. The study investigated prior exposure to home country, ethnic, cultural, and social literacy practices that occurred in various contexts during a nine-month period. This analysis revealed a phenomenon I termed peripheral ritualized practices. Exposure to peripheral ritualized practices over time creates positive changes in attitudes toward multilingualism and diversity.  相似文献

Are You My Grandmother?: Constructing and Maintaining Stepgrandparent Identity and Roles     

Becky L. DeGreeff  Ann Burnett 《Communication quarterly》2017,65(5):603-623

The disruption of the biological family unit due to divorce or separation followed by remarriage or re-partnering has a profound impact on every family member, including extended family members. An individual becomes a stepgrandparent through later life re-partnering, when an adult child becomes a stepparent, or when a stepchild becomes a parent. In order to gain a greater understanding of the communication influencing the development and maintenance of stepgrandparent roles and identity, a qualitative interpretive analysis method was employed as a guide for interviews with 41 adult stepfamily members across two generations of stepfamily membership: stepparents and stepgrandparents.  相似文献   

Relational Maintenance Strategies During the Post Sex Time Interval     

Amanda Denes  Anuraj Dhillon  Annika C. Speer 《Communication quarterly》2017,65(3):307-332

The present study contributes to a growing line of research exploring the role of post sex communication in building and sustaining romantic relationships. More specifically, this study explores the use of relational maintenance strategies during the post sex time interval (PSTI). One-hundred and fifty-two individuals completed surveys after sexual activity and indicated the relational maintenance strategies they enacted during the PSTI. Results revealed that individuals enact the strategies of positivity and assurances to the greatest degree during the PSTI. Furthermore, extending the post sex disclosures model, results revealed that orgasm predicted differences in the use of assurances during the PSTI and that the strategy of assurances mediated the association between orgasm and several relationship outcomes (i.e., liking, commitment, control mutuality, and satisfaction). These findings suggest that individuals may use the PSTI as a time to reinforce their commitments to their partners, and that such behavior is associated with characteristics of the sexual episode and relationship outcomes. The implications of these findings for research on relational maintenance and post sex behavior are discussed.  相似文献
