Exploiting grid computing, desktop grids and cloud computing for e-science: Future directions
No full textPurposeThe purpose of this paper is to examine three different, but related, distributed computing technologies in the context of public‐funded e‐science research, and to present the author's viewpoint on future directions.Design/methodology/approachThe paper takes a critical look at the state‐of‐the‐art with regard to three enabling technologies for e‐science. It forms a set of arguments to support views on the evolution of these technologies in support of the e‐science applications of the future.FindingsAlthough grid computing has been embraced in public‐funded higher education institutions and research centres as an enabler for projects pertaining to e‐science, the adoption of desktop grids is low. With the advent of cloud computing and its promise of on‐demand provisioning of computing resources, it is expected that the conventional form of grid computing will gradually move towards cloud‐based computing. However, cloud computing also brings with it the “pay‐per‐use” economic model, and this may act as stimulus for organisations engaged in e‐science to harvest existing underutilised computation capacity through the deployment of organisation‐wide desktop grid infrastructures. Conventional grid computing will continue to support future e‐science applications, although its growth may remain stagnant.Originality/valueThe paper argues that there will be a gradual shift in the underlying distributed computing technologies that support e‐science applications of the future. While cloud computing and desktop grid computing will gain in prominence, the growth of traditional cluster‐based grid computing may remain dormant.</jats:sec
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
