Editorial of Special Issue of National Identities: Alevism as an ethno-religious identity: Contested boundaries
No abstract for editorial but this is the opening paragraph:
This special issue on Alevism and trans/national Alevi identity critically engages with the relationship between religion, ethnicity and national identity. The core issues are as follows:
• how ethnicity and religion are conceptualised for a relatively invisible ethnic group in different national contexts;
• how religion and ethnicity intersect when Alevism is both a faith and an ethnic identity, especially when conceptions of that identity are contested;
• how identity is shaped through state policies within different national policy contexts and how etic definitions of minority communities are constructed by the state or other agencies with the power to impose them on the community in contrast to the emic or self-definitions of Aleviness from within the Alevi community;
• how despite the fragmented, heterogeneous nature of Alevi communities, there is also a sense of a single, transnational imaginary community, at least for the purposes of political assimilation/integration and activism;
• how education and other arenas of political, religious and cultural engagement at local, national and transnational levels create the possibilities, both positively and negatively, for future action/policy to situate minority ethnic communities
A Hybrid-ARQ System Using Rate-Compatible Trellis Codes Designed for Rayleigh Fading
This paper presents classes of rate-compatible trellis codes designed for channels with flat, slow Rayleigh fading. The codes thus described are ﲭultiple TCM (MTCM) codes as proposed by Divsalar and Simon - i.e., codes in which multiple symbols are associated with each transition through the trellis; by applying appropriate puncturing tables to low-rate MTCM codes, we obtain families of MTCM codes, all of which can be decoded with (essentially) the same decoder.By means of computer search, several such families are designed so that each family member is at least as good as any comparable code in the literature. (ﲇood here is defined in terms of minimum time diversity and minimum squared product distance, the most important parameters for performance over Rayleigh fading channels.) A protocol to implement these rate-compatible trellis codes in a type-II hybrid ARQ format with only a low-rate feedback channel is described. Upper bounds on the resulting bit error rate are developed and the results are used to select the best adaptive code from several possibilities. Simulation results comparing the proposed scheme with fixed-rate codes of the same throughput show substantial coding gain. Finally, a protocol modification limiting the variability of the code rate over a frame is described; this modification eliminates the need for excessive buffering, with a very small effect on performanc
