    ABSTRACT FOR THE BOOK: Nowhere on Earth is there an ecological transformation so swift and so extreme as between the snow-line of the high Andes and the tropical rainforest of Amazonia. The different disciplines that research the human past in South America have long tended to treat these two great subzones of the continent as self-contained enough to be taken independently of each other. Objections have repeatedly been raised, however, to warn against imagining too sharp a divide between the people and societies of the Andes and Amazonia, when there are also clear indications of significant connections and transitions between them. Rethinking the Andes–Amazonia Divide brings together archaeologists, linguists, geneticists, anthropologists, ethnohistorians and historians to explore both correlations and contrasts in how the various disciplines see the relationship between the Andes and Amazonia, from deepest prehistory up to the European colonial period. The volume emerges from an innovative programme of conferences and symposia conceived explicitly to foster awareness, discussion and co-operation across the divides between disciplines. Underway since 2008, this programme has already yielded major publications on the Andean past, including History and Language in the Andes (2011) and Archaeology and Language in the Andes (2012)

    Between Andes and Amazon: The genetic profile of the Arawak-speaking Yanesha

    No full text
    The Yanesha are a Peruvian population who inhabit an environment transitional between the Andes and Amazonia. They present cultural traits characteristic of both regions, including in the language they speak: Yanesha belongs to the Arawak language family (which very likely originated in the Amazon/Orinoco lowlands), but has been strongly influenced by Quechua, the most widespread language family of the Andes. Given their location and cultural make-up, the Yanesha make for an ideal case study for investigating language and population dynamics across the Andes-Amazonia divide. In this study, we analyze data from high and mid-altitude Yanesha villages, both Y chromosome (17 STRs and 16 SNPs diagnostic for assigning haplogroups) and mtDNA data (control region sequences and 3 SNPs and one INDEL diagnostic for assigning haplogroups). We uncover sex-biased genetic trends that probably arose in different stages: first, a male-biased gene flow from Andean regions, genetically consistent with highland Quechua-speakers and probably dating back to Inca expansion; and second, traces of European contact consistent with Y chromosome lineages from Italy and Tyrol, in line with historically documented migrations. Most research in the history, archaeology and linguistics of South America has long been characterized by perceptions of a sharp divide between the Andes and Amazonia; our results serve as a clear case-study confirming demographic flows across that \u2018divide\u2019

    Sound Comparisons hosts over 90,000 individual word recordings and 50,000 narrow phonetic transcriptions from 600 language varieties from eleven language families around the world. This resource is designed to serve researchers in phonetics, phonology and related fields. Transcriptions follow new initiatives for standardisation in usage of the IPA and Unicode. At soundcomparisons.com, users can explore the transcription datasets by phonetically-informed search and filtering, customise selections of languages and words, download any targeted data subset (sound files and transcriptions) and cite it through a custom URL. We present sample research applications based on our extensive overage of regional and sociolinguistic variation within major languages, and also of endangered languages, for which Sound Comparisons provides a rapid first documentation of their diversity in phonetics. The multilingual interface and user-friendly, ‘hover-tohear’ maps likewise constitute an outreach tool, where speakers can instantaneously hear and compare the phonetic diversity and relationships of their native languages

    Catastrophe Survived? The Failure of the Tragic in Moira Buffini'sWelcome to Thebes

    Get PDF
    In Moira Buffini's Welcome to Thebes (2010) Antigone fails to reach her tragic destiny, the city of Thebes fails to become an autonomous democratic state, and the audience fails to witness the splendour of the ancient heroine. In this paper I consider these three failures as interrelated and dependent upon one another, arguing, along psychoanalytic lines, that they register changing attitudes towards knowledge and the Other which ultimately determine the meaning of ‘failure’. However, in order to better appreciate the contemporary scope of failure, I draw on both Lacan and Baudrillard, highlighting convergences between the two theorists. In particular, I argue that Lacan's notion of the inconsistent Other can be supplemented by Baudrillard's notion of the impossible exchange. Further, the relevance of these notions for theatre and spectatorship is discussed in detail, as they both invite spectators to reflect on their own involvement in the scene they witness and the ontological conditions of (their own) absence and presence. Failure to do so possibly indicates an irreparable loss of the critical capacity which we have always considered central to radical thought

    T Regulatory Cells Are Markers of Disease Activity in Multiple Sclerosis Patients

    FoxP3+ Treg cells are believed to play a role in the occurrence of autoimmunity and in the determination of clinical recurrences. Contradictory reports are, however, available describing frequency and function of Treg cells during autoimmune diseases. We examined, by both polychromatic flow cytometry, and real-time RT-PCR, several Treg markers in peripheral blood mononuclear cells from patients with multiple sclerosis (MS), an autoimmune disease affecting the central nervous system. We found that Tregs, as defined by CD25, CD39, FoxP3, CTLA4, and GITR expression, were significantly decreased in stable MS patients as compared to healthy donors, but, surprisingly, restored to normal levels during an acute clinical attack. We conclude that Treg cells are not involved in causing clinical relapses, but rather react to inflammation in the attempt to restore homeostasis

    An African Ancestry-Specific Allele of CTLA4 Confers Protection against Rheumatoid Arthritis in African Americans

    Get PDF
    Cytotoxic T-lymphocyte associated protein 4 (CTLA4) is a negative regulator of T-cell proliferation. Polymorphisms in CTLA4 have been inconsistently associated with susceptibility to rheumatoid arthritis (RA) in populations of European ancestry but have not been examined in African Americans. The prevalence of RA in most populations of European and Asian ancestry is ∼1.0%; RA is purportedly less common in black Africans, with little known about its prevalence in African Americans. We sought to determine if CTLA4 polymorphisms are associated with RA in African Americans. We performed a 2-stage analysis of 12 haplotype tagging single nucleotide polymorphisms (SNPs) across CTLA4 in a total of 505 African American RA patients and 712 African American controls using Illumina and TaqMan platforms. The minor allele (G) of the rs231778 SNP was 0.054 in RA patients, compared to 0.209 in controls (4.462×10−26, Fisher's exact). The presence of the G allele was associated with a substantially reduced odds ratio (OR) of having RA (AG+GG genotypes vs. AA genotype, OR 0.19, 95% CI: 0.13–0.26, p = 2.4×10−28, Fisher's exact), suggesting a protective effect. This SNP is polymorphic in the African population (minor allele frequency [MAF] 0.09 in the Yoruba population), but is very rare in other groups (MAF = 0.002 in 530 Caucasians genotyped for this study). Markers associated with RA in populations of European ancestry (rs3087243 [+60C/T] and rs231775 [+49A/G]) were not replicated in African Americans. We found no confounding of association for rs231778 after stratifying for the HLA-DRB1 shared epitope, presence of anti-cyclic citrullinated peptide antibody, or degree of admixture from the European population. An African ancestry-specific genetic variant of CTLA4 appears to be associated with protection from RA in African Americans. This finding may explain, in part, the relatively low prevalence of RA in black African populations
