    Occurrence of <i>Neogloboquadrina pachyderma</i> new subspecies in the shelf-slope sediments of northern Indian Ocean

    72-75Specimens of N. pachyderma (Ehrenberg) which are considered to be typical bipolar, cooler water species are described in the recent shelf-slope sediments of the northern Indian Ocean as far north as 23° N in the Arabian Sea and 18° N in the Bay of Bengal. Studies of hydrological conditions in the Indian Ocean reveal that the Subtropical Subsurface Water Mass is traceable as far north as the Gulf of Aden, and the Indian Ocean Deep Bottom Water Mass originating in the deepest levels of the South Polar region moves northwards and passing through the equator enters the Arabian Sea and the Bay of Bengal; and also the Indian Central Water Mass and the Equatorial Water Mass having different T-S relationships are responsible for the transport of this species to the middle and low latitudes. It is proposed that the forms which occur in the low latitudes (up to 25°s N) in the northern Indian Ocean be referred to henceforth as (1) (a) N. pachyderma dextralis typica Setty, n. subsp. (sensu stricto) if the species is right-coiled, and (b) Neogloboquadrina. pachyderma sinistralis typica n. subsp. Setty (sensu stricto) if the species is left-coiled; (2) as Neogloboquadrina. pachyderma dextralis, Setty n. subs. (sensu stricto) for those which occur in the mid-latitudes; and (3) all those forms which occur in the high latitudes as Neogloboquadrina. pachyderma (sensu stricto) where they are typically left coiled. Thus speciation and subspeciation into definite latitudinal zones helps greatly in the standardization of this species

    Diffusive author(s), cohesive author: Analysis of S/N (1994)

    No full text
    This study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)

    Going Beyond Counting First Authors in Author Co-citation Analysis

    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

    Dispelling the Myths Behind First-author Citation Counts

    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    Squamous cell carcinoma in a chronically rejected renal allograft

    The malignant degeneration of a chronically rejected kidney allograft has been rarely reported. Almost invariably such malignancies originated in the transitional epithelium. We herein present the first occurrence of squamous cell carcinoma (SCC), originating from occult donor cells, in a chronically rejected renal allograft. Nearly 20 years after chronic rejection and loss of function of a cadaver renal graft, our patient developed increasing abdominal discomfort, decrease in appetite and weight loss. A CT-scan of the abdomen showed an abnormally enlarged and irregularly contoured mass at the level of the rejected allograft. Given the clinical and radiologic picture suggestive of either an infectious or intraparenchymal hemorrhagic process, a transplant nephrectomy was performed. At surgery, it was immediately evident that a malignant degenerative process had affected the graft. The histological features of the specimen were diagnostic for a well-differentiated SCC. The donor origin of the tumor was established through a DNA microchimerism assay performed on the operative specimens. The patient did well after resection of the malignancy, although he died 5 months later owing to a myocardial infarction. In summary, even several years following the transplant, the possibility of a malignancy of donor origin developing within a failed allograft should always be considered as part of the differential diagnosis in unusual post-transplant settings

    Can archives of audiovisual TV interviews be used to make authors more visible to students, and thereby reduce the learning gap between native and non-native language speakers in college classes? We examined students in a college course who learned about one scholar&apos;s ideas through watching an audiovisual TV interview (i.e., visible author format) and about another scholar&apos;s ideas through reading a formal text description (i.e., invisible author format). For the invisible author, native language speakers scored significantly higher than the non-native language speakers on a corresponding exam question (i.e., a cognitive measure), generated more words on the exam question (i.e., a motivational measure), and mentioned the author&apos;s name more often in answering the exam question (i.e., an affective measure). For the visible author, the groups did not differ on any of these measures. These findings provide evidence for the idea that making the author visible through audiovisual TV interviews can eliminate the learning gap between native and non-native language speakers. 3 Universities around the world serve students who are non-native speakers of th

    The vanishing author in computer-generated works: a critical analysis of recent Australian case law

    No full text
    Abstract The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals

    The construction of Karen Karnak: The multi-author-function

    No full text
    This thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
