    Affect, Identity, and Ethnicity: Towards a Social-Psychological Mode of Ethnic Attainment

    Since the days of Shils and Geertz it has been common to refer to ethnicity as a bond, a tie, or an attachment. Shils used the term tie in the title of his seminal 1957 article to refer to a set of social relationships, including what he called civil, kinship, sacred, and primordial. The primordial tie was notable for the ineffable significance which social actors attribute to it and to the relationship which it engenders: the attachment [is] not merely to the other ... as a person, but as a possessor of certain especially \u27significant relational\u27 qualities, which could only be described as primordial. The attachment ... is not just a function of interaction. ^1 Subsequently Geertz developed the notion of ethnic attachment as an affect and identity, or better yet, an affect-centered identity. The intention, often quite explicit, of these thinkers and the many who followed them was to emphasize the emotional quality of ethnicity as an explanation of its persistence and power. At the same time, as an emotional and not rational phenomenon, ethnicity was expected to decline and disappear under the onslaught of modern rationalizing social forces. This essay returns to the issue of ethnicity as an affective relationship. It will argue that affect is indeed a critical element in ethnicity but that the theoretical treatment of ethnic affect has tended to be counterproductive

    Algebraic groups and compact generation of their derived categories of representations

    Full text link
    Let kk be a field. We characterize the group schemes GG over kk, not necessarily affine, such that Dqc(BkG)\mathsf{D}_{\mathrm{qc}}(B_kG) is compactly generated. We also describe the algebraic stacks that have finite cohomological dimension in terms of their stabilizer groups.Comment: 17 pages; generalized Theorems A and C; final version; some minor corrections and updated citation

    Video killed the 'PDF' star: taking information resource guides online

    Easy-to-use technologies now allow librarians to create their own customised digital and video tutorials. This article takes a look at publisher-created video tutorials. It considers the pros and cons of libraries creating their own video-format guides, and elaborates on DCU Library's own experience in producing video-based tutorials on databases customised to local needs using Camtasia and Screentoaster

    The telescope conjecture for algebraic stacks

    Full text link
    Using Balmer--Favi's generalized idempotents, we establish the telescope conjecture for many algebraic stacks. Along the way, we classify the thick tensor ideals of perfect complexes of stacks.Comment: 20 page
