French-Muslims and the Hijab: An Analysis of Identity and the Islamic Veil in France

This article examines how Muslims living in France construct, and negotiate their identities in the wake of Law 2004–228, a French law banning the wearing of the Islamic veil in French public schools. This research finds that Muslims deem the Islamic veil or hijab to be a fundamental part of their identity. Muslims describe the hijab as being an important and salient symbol of Islam that runs counter to France's concept of secularism or laïcité. Moreover, French-Muslims assert regulations like Law 2004–228 represent France attempting to control Muslim identity and forcefully integrate this population.     

The Code of Food and Tradition: Exploring a Lebanese (American) Speech Code in Practice in Flatland

This study examines a recognizable speech code, the code of food and tradition, as displayed among members of a Lebanese community in Flatland, located in the central United States. Based upon in-depth interviews with 20 participants and three months of participant observation at a Lebanese food festival, we identify communication that is gendered, generationally shaped, and focused on tradition. These are manifest in both beliefs and everyday practices. Drawing upon Speech Codes Theory and Bakhtinian perspectives, we examine the communicative practices and beliefs as to what it means to “be Lebanese.”     

Conflict Management Styles: The Role of Ethnic Identity and Self-Construal among Young Male Arabs and Americans

This cross-cultural study compared young male Arabs’ and young male Americans’ perceptions of their ethnic identity, self-construal, and conflict management styles. Findings indicated that Arabs had stronger ethnic identity than Americans. Arabs were both more independent and interdependent than American participants. Conflict style comparisons demonstrated that Americans chose the emotional expression, dominating, and neglect styles more than Arabs, and Arabs chose the integrating, third-party help, and avoiding styles more than Americans. Participants did not differ in their preference of the compromising and obliging conflict management styles. In terms of the relationships among ethnic identity, self-construal, and conflict styles, little difference was found between the two cultural groups. The integrating, compromising, avoiding, and neglect conflict management styles were predicted by both independent and interdependent self construal for both cultural groups. The obliging and third-party conflict styles were positively predicted by interdependent self-construal. The dominating style was predicted by independent self-construal and ethnic identity. The only conflict style that was predicted differently among Arab and American participants was the emotional expression style. Among American participants, interdependent self-construal and ethnic identity predicted emotional expression style. For Arabs, independent self-construal predicted the emotional expression style.     

Bicultural Identity Negotiation,Conflicts, and Intergroup Communication Strategies

This qualitative study explores the significant yet understudied topic of bicultural identity and intergroup-intercultural communication. Ting-Toomey’s identity negotiation theory and Giles’ communication accommodation theory guide this investigation into the meaning construction of “bicultural identity” of Asian/Caucasian individuals and their intergroup communication strategies. Bicultural identity development is a multilayered, complex lived experience. Response analysis to the research questions revealed eight thematic patterns such as bicultural construction of integrated identity, distinctive communication practice, and identity buffering strategies. These patterns culminate to the proposed idea of a “double-swing bicultural identity” model. The study concludes with a discussion on contributions, limitations, and future directions.     

Heterogeneity in national identity construct: Example of Singapore using network analysis

Singapore has been undergoing a negotiation of its national identity as it celebrated its fifty years of independence. The seemingly lack of consensus on the nation’s identity has brought about much heated debates about Singapore’s governance. However, the construction of one’s definition of national identity is often shaped not by the political discourse but by what one has experienced in his or her formative years. Citizens who experienced different stages of nationhood are hence likely to develop different interpretations of what it means to be a citizen of the nation. In this study, using network analysis, we sought to examine how the definition of national identity differed between citizens who were born before Singapore’s independence, and hence experienced the early nation-building phase of the country, vis-à-vis citizens who were born after the country’s independence. 1000 native Singaporeans indicated which of the 27 identity markers were important for an immigrant to have to be accepted as a Singaporean. The analysis revealed that there were differences in the number of clusters within the identity networks of individuals born before versus after Singapore’s independence. The strength of the identity network of individuals born before independence was also stronger. Using simulated networks, we also showed how a change in endorsement of more influential markers had stronger effect on the overall identity network than a change in endorsement of less influential markers among individuals born before independence.     

Together we stand? Belonging motive moderates the effect of national ingroup salience on attitudes towards ethnic minorities

Common ingroup categorization reduces outgroup prejudice. This link is moderated by distinctiveness motives (i.e., individuals perceiving this identity as too inclusive). Yet, Optimal Distinctiveness Theory states that both distinctiveness and belonging motives shape intergroup attitudes. For the first time we tested the hypothesis that belonging and distinctiveness motives jointly moderate common ingroup categorization effects. Using a flag-priming paradigm, two studies showed that, when national ingroup identity was salient, only belonging motives predicted positive attitudes towards outgroups (Study1: Syrians in Turkey, N = 184; Study 2: Maghrebis in France N = 151). This was corroborated by sensitivity analyses on aggregated data (N = 335). These results suggest that national identification may lead to positive outgroup attitudes for individuals who derive belonging from it.

Activists of themselves: Liminality of Instagram and its role in the ethnic identity construction processes of third generation British Sikhs to their imagined identities

As a result of the rapid evolution of computer culture, social media and networking websites now provide the primary socialisation platforms for individuals across the world. With characteristics such as transcending time, space, and even cultures, these platforms impact individuals through increased interactions. Although past research shows how social media impacts on individuals’ cultural affiliations and identity construction processes, research neglects to understand the role and impact of the characteristics of social media and networking environments as individuals engage in these virtual spaces. This paper uses Instagram as a case study, to demonstrate the liminal nature of social media spaces and looks at how this virtual space and its characteristics evoke a sense of reflexivity with regards to identity construction amongst young British Sikhs in the U.K. We highlight how the empowering characteristics of this virtual space impact their identity and just how the communities that are formed by individuals through Instagram, act as a further acculturative agent, as they attempt to deal with the tensions that they experience as a result of being both British and Sikh. Findings implicate how brands can engage with and support the individuals going through this reflective identity re/construction process.
