    Polymorphism of Eimerian Oocysts: A Dilemma Posed by Working with Some Naturally Infected Hosts

    No full text
    Morphological variation of sporulated oocysts within individual eimerian species is well documented (Joyner, 1982. In Biology of the Coccidia, P. L. Long (ed.). University Park Press, Baltimore, pp. 35-62). In some cases, oocysts of a single eimerian species are known to vary in size by as much as 40% during patency (Duszynski, 1971, Journal of Parasitology 57: 948-952). During a survey to determine the prevalence of coccidiosis in sandhill cranes (Grus canadensis) wintering in New Mexico (Parker and Duszynski, 1986, Journal of Wildlife Diseases 21: 25-35), marked polymorphism was observed among sporulated oocysts of Eimeria reichenowi. Oocysts were obtained from intestinal contents of cranes necropsied in the field and processed for study by routine sporulation and flotation techniques (Duszynski et al., 1982, Journal of Parasitology 68: 1,146-1,148). Initially, oocysts were categorized into 5 groups based on obvious qualitative/quantitative features including oocyst wall texture, appearance of the sporocyst residuum, and the number of polar bodies. Fifty-seven of 118 (48%) fecal samples with E. reichenowi contained 2 or more morphological types of oocysts. Oocysts were measured under oil immersion (100 x Neofluar objective, Zeiss Universal Photomicroscope) and differences between the 5 oocyst groups were tested for significance (P \u3c0.05) using the Student-Newman-Keuls procedure

    Revisiting the Code: Clarifying Name-Bearing Types for Photomicrographs of Protozoa

    No full text
    In 1988, Bandoni and Duszynski argued that individuals involved in the taxonomy and systematics of the coccidia should become familiar with the 3rd edition of the Code of Zoological Nomenclature (Ride et aI., 1985) and tried to reiterate the importance and utility of designating some form of type specimens and archiving them in appropriate museums. Their intent was to create an awareness among biologists working with coccidia (or other protists) of the value of designating type specimens. In the decade since their admonition, bench scholars working with coccidia, and journal editors to whom they submit their work, have begun to endorse the type concept by requiring that some form of type specimen be submitted before new species names and descriptions are published. Although some authors still submit samples of oocysts preserved in standard fixatives (for reasons why this option is less than optimal, see Duszynski and Gardner [1991]), the majority submit photomicrographs of sporulated oocysts as their type species to various accredited museums. The issue that arises is what to call these kinds of type specimens. Proposed here is to add the prefix photo- to appropriate terminology already sanctioned by the Code to help clarify existing terminology. Because increasing numbers of photomicrographs are being submitted to accredited museums to archive new species, there seems a need for precise definitions, so those who submit photomicrographs of sporulated oocysts and/or other life cycle stages of coccidia will know, unambiguously, how to define their name-bearing type specimen

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    No full text
    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
