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
Designing role-based view for object-relational databases
No full textIn a federated database system, a view mechanism is crucial since it is used to define exportable subsets of data ; to perform a virtual restructuring d ataset; and to construct the integrated schema. The view service in federated databa se systems must be capable of retaining as much semantic information as possible. The object-oriented ( 0 - 0 ) model was considered the suitable canonical data model since it meets the original criteria for canonical model selection. However, with the emergence of stronger object-relational (0 -R ) model, the re is a clear argument for using an 0 - R canonical model in the federation. Hence, research should now focus on th e development of semantically powerful view mechanism for th e newer model. Meanwhile, the availability of real 0 -R technologies offers researchers the opportunity to develop different forms of view mechanisms.
The concept of roles has been widely studied in 0 - 0 modelling and development. The role model represents some characteristics that the traditional 0-0 model lacked, such as object migration, multiple occurrences and context-dependent access. While many forms of 0-0 views were designed for the 0-0 canonical model, one option was to extend the 0-0 model to incorporate a role model. In a role model, the real entity is modelled in the form of a role rather than an object. An object represents the permanent properties of an entity is a root object; and an object represents the temporary properties of an entity is a role object.
The contribution of this research is to design a view system that employees the concept of roles for the 0 -R canonical model in a federated database system. In this thesis, an examination of the current 0 -R metamodel is provided first in order to provide an environment for recognising the roleview metadata and measuring the view performance; then a Roleview Definition Language (RDL) is introduced, along with the semantics for defining virtual classes and generating virtua l extents; finally, a working prototype is provided to prove th e role-based view system is implementable and the syntax is semantically correct

Methods for creating corner colored Wang tiles
No full textCorner and edge colored Wang tiles are used in computer graphics to synthesize large seamless and non-periodic textures while reducing the storage requirements that expansive textures require. Wang tiles have matching constraints that dictate which tiles may be placed next to each other to ensure a seamless transition between adjacent tiles; while using a finite set of tiles for use in tiling limits the storage required to generate texture. The most popular technique in the current literature for constructing Wang tiles is to combine samples from an image and perform a graph cut between four abutted samples and an overlay sample where the graph cut should find the cut that selects pixels that creates the least objectionable tile. This thesis introduces new methods for generating corner colored Wang tiles and discusses the important characteristics in generating them. Synthesized Wang Tiles (SWT) use a controlled texture synthesis algorithm for tile construction. Bilinear Blended Wang Tiles (BLWTiles) use blending for tile construction and Gauss Laplace Pyramid Blended Wang Tiles (GLWTiles) use blending over different levels of Laplacian pyramids for tile construction. BLWTiles and GLWTiles are evaluated procedurally and can be mapped to GPU evaluation, while the SWTile method is intended to precompute a set of Wang tiles. The BLWTile, GLWTile, and SWTile techniques can supplement existing methods for creating Wang tiles. The characteristics that influence the quality of corner colored Wang tiles can serve to improve new and existing tile creation techniques
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full textWe 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
Impero o stato-nazione? La modernità intellettuale in Cina
No full textChe cosa è la Cina? Un Impero o uno Stato-Nazione? Che cosa ha permesso gli sviluppi di un potente apparato capace di controllare un territorio immenso abitato da innumerevoli etnie? E che cosa significa parlare di una sua «modernità», non rispondente ai canoni che di solito identificano pensiero moderno e civiltà occidentale? Sono queste le domande poste al centro del saggio di Wang Hui. Ricostruendo una vera e propria genealogia del pensiero «moderno» cinese, l'Autore rilegge gli esiti contemporanei della Cina alla luce delle molteplici costruzioni intellettuali e forme politiche che ne hanno caratterizzato la storia.
Il libro è la prima traduzione in lingue occidentali di una ricerca di grande innovazione storiografica e teorica che ha imposto all'attenzione internazionale un Autore oggi universalmente riconosciuto come uno dei più importanti intellettuali cinesi.
Un testo che propone al lettore una conoscenza dell'identità cinese che supera gli approcci giornalistici e i tanti stereotipi che ne hanno accompagnato il recente processo di modernizzazione
