Federated identity management systems for cyberinfrastructure: SAML vs. PKIX
Full text linkIn scientific infrastructures researchers accessing computing and other resources (e.g., instruments, data) across institutional boundaries rely on federated identity management systems. Multiple competing technologies are in use for this purpose, including Security Assertion Markup Language (SAML) and Public Key Infrastructure with X.509 Certificates (PKIX). These systems have found favor in different scientific computing communities but it is unclear what the difference in preference is based upon. In this study we discuss the security, usability, privacy and trust model assumptions of SAML and PKIX systems for researchers authenticating to grid computing systems across multiple domains. We provide a comparison of these systems to highlight where they provide equivalent functionality and where one technology is superior.Item withdrawn by Laura Spradlin ([email protected]) on 2014-04-28T13:29:51Z

Group Management Use Cases, version 1.2
Full text linkThese use cases describe how individuals need to manage and use group definitions. In its simplest form, a group definition is a list of people that needs to be maintained and used for some ongoing purpose. GRP-02 through GRP-16 were originally derived from a project-wide user needs study conducted in early 2017 by the XSEDE Community Infrastructure (XCI) team’s Requirements Analysis and Capability Delivery (RACD) activity. However, these use cases are consistent with group features in many systems, so their usefulness is by no means specific to XSEDE.Open Restriction set for Item 111717 on 2019-08-01T17:56:15Z with date null by [email protected] by Lee Liming ([email protected]) on 2019-08-01T18:00:44Z

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

XSEDE Service Provider Integration Use Cases, version 1.0
No full textThis document outlines the XSEDE system features that allow Service Providers (SPs) to integrate their resources with the rest of the XSEDE system. XSEDE defines SPs as “autonomous entities that agree to coordinate with XSEDE and each other to varying degrees.” The use cases in this document describe some of the ways this coordination happens.National Science Foundation OCI-1053575Ope

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
