    “Naturalizing the nation”: the rise of naturalistic nationalism in the United States and Canada

    Get PDF
    Perhaps the most vexing problem in philosophy and social theory concerns the relative importance of material and ideal factors for social action. Karl Marx, for instance, with his notion of base and superstructure and his materialistic interpretation of the dialectic process, made a clean break from the idealism of his Hegelian heritage (McLellan 1977:390; Swingewood 1991:62–63). Nevertheless, idealism proved resilient and later came to inform the thinking of both actor-oriented (that is, phenomenologist, ethnomethodologist, symbolic interactionist) and structure-oriented (that is Functionalist, Structuralist) theorists

    Workshop island 3: algebraic aspects of integrability. Introduction to an additional volume of selected papers arising from the conference on algebraic aspects of integrable systems, Island 3, Islay 2007

    As did the very first ISLAND workshop, ISLAND 3 took place on the Hebridean island of Islay, providing a beautiful and serene surrounding for the meeting which ran for over four days. Building on the success of the previous meetings, ISLAND 3 saw the largest number (so far) of participants coming from countries all over the world. A complete list can be found below

    Koszul incidence algebras, affine semigroups, and Stanley-Reisner ideals

    Full text link
    We prove a theorem unifying three results from combinatorial homological and commutative algebra, characterizing the Koszul property for incidence algebras of posets and affine semigroup rings, and characterizing linear resolutions of squarefree monomial ideals. The characterization in the graded setting is via the Cohen-Macaulay property of certain posets or simplicial complexes, and in the more general nongraded setting, via the sequential Cohen-Macaulay property.Comment: 31 pages, 1 figure.

    In search of the authentic nation: landscape and national identity in Canada and Switzerland

    Get PDF
    While the study of nationalism and national identity has flourished in the last decade, little attention has been devoted to the conditions under which natural environments acquire significance in definitions of nationhood. This article examines the identity-forming role of landscape depictions in two polyethnic nation-states: Canada and Switzerland. Two types of geographical national identity are identified. The first – what we call the ‘nationalisation of nature’– portrays zarticular landscapes as expressions of national authenticity. The second pattern – what we refer to as the ‘naturalisation of the nation’– rests upon a notion of geographical determinism that depicts specific landscapes as forces capable of determining national identity. The authors offer two reasons why the second pattern came to prevail in the cases under consideration: (1) the affinity between wild landscape and the Romantic ideal of pure, rugged nature, and (2) a divergence between the nationalist ideal of ethnic homogeneity and the polyethnic composition of the two societies under consideration

    Results of the 2007-2008 Illinois Hunter Harvest Survey

    Grant/Contract No: W-112-R-17A random sample of 3,000 potential hunters was selected from among 2007 Illinois Habitat Stamp and hunting license purchasers. An 8-page questionnaire was successfully mailed to 2,906 of the 3,000 individuals. We received 1,625 returned questionnaires, 1,620 of which were usable, for a 56% response rate. Comparisons of harvest estimates from the 2006-2007 season to the 2007-2008 season suggest harvest decreased for 10 game animal categories (rabbit, quail, pheasant, dove, gray partridge, fox squirrel, gray squirrel, red fox, gray fox, and opossum), and increased for 3 categories (woodcock, raccoon, and coyote). License sales increased 0.4% from 282,000 sold for the 2006 season to 283,000 sold in the 2007 season. This represents a recovery in license sales of less than 1% since the lowest level on record (since 1938) in 2005. Low license sales may be related to increasing difficulty in finding land to hunt. Resident hunters pursuing deer (61%) and small game species (51%) reported little difficulty in gaining access to hunting lands. However, all other seasons were associated with more difficulty in accessing land. Efforts should be undertaken to ensure that hunters are aware of the locations of public hunting lands associated with these seasons. Few residents reported leasing land (4%) or hiring outfitters (1%) to access land.INHS Technical Report Prepared for Illinois Department of Natural Resources; Illinois Natural History Surve

    DYNAMITE: ANARCHISM, MODERNISM, AESTHETICS

    Get PDF
    This book argues for the intersection of anarchist theory, modernist writers, and aesthetic innovations under the sign of "the bomb." Individual chapters concern such figures as Joseph Conrad, Richard Wagner, Henry Adams, Andrei Bely, Edna St. Vincent Millay, Upton Sinclair, John Dos Passos, and Katherine Ann Porter, as well as collectivities like the Surrealists and the Dadaists. Anarchists such as Peter Kropotkin, Emma Goldman, and Michael Bakunin are also important to the text. The original version of this text was produced as a dissertation at the University of California Berkeley. Committee members were Carolyn Porter, Ann Banfield, and the late Michael Rogin. Three chapters--those on Conrad, Wagner, and the Sacco-Vanzetti case--were published in refereed academic journals. A synopsis of the argument was published in The Turn of the Century, Walter Pape, editor (Berlin and New York: Walter de Gruyter) 1995. Dynamite had been approved for publication in the Atopia series of Stanford University Press when major changes at the press resulted in the abolition of the series

    Skin-Tone and Academic Achievement Among 5-year-old Mexican Children

    Get PDF
    Skin-tone based social stratification has been characterized as an enduring part of the U.S. racial landscape (Hunter, 2002). Despite the plethora of research that examines the racial disparities in education (e.g., Reardon & Portilla, 2015), and an emerging literature finding that lighter skin-tones are associated with higher educational attainment among adults (Hunter, 2002) few studies have examined whether similar processes emerge during early childhood. Thus, grounded in Garcia Coll and colleagues’ (1996) integrative model, we tested whether skin-tone predicted children’s academic achievement, and whether these relations were modified by children’s ethnic-racial identification (i.e., positive ethnic-racial attitudes and centrality). Consistent with expectations, darker skin-tones were associated with lower math scores. Positive attitudes did not significantly moderate the relation between skin-tone and academic achievement. However, contrary to our hypothesis, high levels of ethnic racial centrality strengthened the association between skin-tone and academic achievement. Conclusions: These findings contribute to the literature by providing evidence for the early development of within race skin-tone based disparities in academic achievement and underscoring the need for further exploration of ethnic racial identification as protective or risk factors in the positive development of minority children
