    A new relationship, that of predator and prey, between the coleopteran families Cleridae and Bruchidae is presented

    Diffusions of Multiplicative Cascades

    Get PDF
    A multiplicative cascade can be thought of as a randomization of a measure on the boundary of a tree, constructed from an iid collection of random variables attached to the tree vertices. Given an initial measure with certain regularity properties, we construct a continuous time, measure-valued process whose value at each time is a cascade of the initial one. We do this by replacing the random variables on the vertices with independent increment processes satisfying certain moment assumptions. Our process has a Markov property: at any given time it is a cascade of the process at any earlier time by random variables that are independent of the past. It has the further advantage of being a martingale and, under certain extra conditions, it is also continuous. We discuss applications of this process to models of tree polymers and one-dimensional random geometry.Comment: 30 pages; added section on Holder continuit

    Infectious Diseases Associated With Renal Homotransplantation: I. Incidence, Types, and Predisposing Factors

    Get PDF
    Infectious diseases occurred in 26 of 30 renal homotransplantation patients and contributed to eight of the 12 deaths in this series. There were 52 infections, 17 occurring before and 35 after transplantation. Infections were produced primarily by staphylococci, Pseudomonas species, and the enteric gram-negative bacilli. Staphylococcal infections occurred in 17 of 19 carriers of this organism and in only one of 11 noncarriers. Thirty-three of the 35 postoperative infections followed the intensification of immunosuppressive therapy for treatment of attempted homograft rejection. Granulocytopenia, steroid-induced diabetes, and hypogammaglobulinemia, from suppressive drug therapy, routinely preceded the onset of these complications. The infections, largely of endogenous origin, occurred when the host's defense mechanisms were depressed. © 1964, American Medical Association. All rights reserved

    SPLENIC HOMOTRANSPLANTATION.

    Get PDF
    During the past 12 months, five clinical whole-organ splenic homotransplantations have been carried out with the objective of providing active immunologic tissue for the recipient patients. In one case with hypogammaglobulinemia, it was hoped that the transplanted tissue would alleviate a state of immunologic deficiency. In the other four, all of whom had terminal malignancies, the purpose was to superimpose a state of altered immunologic reactivity upon the host in the hope of thereby suppressing the inexorable growth of the neoplasms. As will be described, these procedures can now be judged in each instance to have been without benefit. Nevertheless, full documentation of the cases seems justified not only because of the many implications of transplantation of immunologically competent tissue, but also because of the potentially important observations made during the care of these patients. In addition, a full account will be presented of the supporting canine studies of splenic homotransplantation, inasmuch as many of the principles of clinical therapy and investigation derived from prior observations in the dog. The fact that it is possible to obtain viable splenic homografts in the dog for as long as two-thirds of a year without the production of runt disease or other harmful effects may have application in future research on bone marrow, other lymphoid, or hepatic homografts

    Lo Stato dell’arte. Fascismo e legittimazione culturale

    Get PDF
    Abbiamo rivolto una serie di domande a Monica Cioli e David Rifkind autori di due importanti volumi sul modo in cui rispettivamente l’arte e l’architettura hanno assunto uno specifico significato politico sotto il fascismo. Ne è uscito un dialogo che mostra come il rapporto tra fascismo e arte non è caratterizzato da una mera appropriazio-ne o da uno sfruttamento reciprocamente funzionale tra artista o architetto e regime fascista. L’arte prepara un’appropriazione specifica della tecnica e introduce all’antropologia politica dell’uomo fascista. Allo stesso modo l’architettura appronta un ordinamento degli spazi urbani coerente e necessaria per la gerarchia dell’ordine della società corporata

    Screening Modernity: Cinema and Sexuality in Ann-Marie MacDonald's Fall On Your Knees

    Get PDF
    In Fall on Your Knees, Ann-Marie MacDonald writes early twentieth-century Cape Breton and New York through attention to the popular culture of the era, particularly in aspects of the visual, including paintings, photographs, and films. Just as the female characters trangress boundaries between normative and queer sexuality, so too the text offers an aesthetic queering of the boundaries between representational media. The representations of 1920s film star Louise Brooks, particularly, guide readers to a supplemental set of cultural meanings carried by her image and to a recognition that representation, like history, is always partial."This article was written with the support of a doctoral fellowship from the Fonds pour la Formation de Chercheurs et l’Aide à Recherche (Fonds FCAR)."https://journals.lib.unb.ca/index.php/scl/article/view/12790/1377
