Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Design and deploy of an Apache Kafka cluster
No full textreservedQuesta tesi riporta l’attività svolta nell’ambito del tirocinio presso l’azienda Acciaierie Valbruna S.p.A. Lo stage ha avuto come obiettivo l’implementazione e la gestione di un ambiente Apache Kafka a scopo di test.
Apache Kafka è un progetto open-source che fornisce una piattaforma per la gestione di flussi di dati in tempo reale tra diversi archivi di dati in modo affidabile e scalabile.
L’ambiente è stato inizialmente distribuito tramite Ansibile, uno strumento che consente la gestione e la distribuzione automatica di sistemi Linux e Windows tramite il paradigma Infrastrutcture as a Code, e successivamente lo stesso ambiente è stato distribuito come cluster di container utilizzando Podman, un’alternativa a Docker.
Il cluster Apache Kafka gestisce la replica di un database MySQL su un database OracleDB 10 (che si comporta come un Oracle DB 9 attraverso l’emulazione) sfruttando una suite di plugin sviluppati per Kafka Connect, che è uno strumento distribuito assieme ad Apache Kafka che facilita la connessione del cluster a diversi tipi di sistemi di dati.
Uno schema registry viene inoltre connesso al cluster per ottimizzare il consumo di spazio e
per gestire più facilmente eventuali modifiche alla struttura delle fonti di dati. Questo registry è un repository che gestisce e convalida gli schema utilizzati nel sistema, in questo caso gli schema del database sorgente.
La prima parte di questo documento riguarda l’analisi dei requisiti proposti dall’azienda concentrandosi anche sulle decisioni progettuali che sono scaturite dai vincoli imposti e le sfide che l’ambiente di test ha presentato.
La seconda parte è dedicata alla descrizione dettagliata dei principali componenti dell’infrastruttura.
La terza parte è dedicata all’effettiva implementazione dell’ambiente con Ansible e a come questo approccio ha portato a un processo di deploy molto più efficiente e più facilmente gestibile rispetto a quello manuale. Inoltre, lo stesso ambiente è stato distribuito come un insieme di container, mettendo in mostra le sfide e i vincoli di questo approccio e approfondendo i pro e i contro di ciascun metodo.
La parte finale del documento riguarda il feedback ricevuto dall’azienda e i miglioramenti necessari che potrebbero essere necessari per poter utilizzare il cluster in produzione.This thesis reports on the activity carried out as part of the internship at the company Acciaierie Valbruna S.p.A. The internship aimed to deploy and manage an Apache Kafka environment for testing purposes.
Apache Kafka is an open-source project that provides a platform for handling real-time data feeds between different data storage in a reliable and scalable way.
The environment was initially deployed through Ansibile, an infrastructure as a code tool that enables the automatic management and deployment of Linux and Windows systems, and after that, the same environment was deployed as a cluster of containers using Podman, an alternative to Docker.
The Apache Kafka cluster handles the replication of a MySQL database onto an OracleDB 10 database (acting as an Oracle DB 9 through emulation) by leveraging a suite of plugins developed for Kafka Connect, which is a tool distributed with Apache Kafka that facilitates the connection of the cluster to several kinds of data systems.
A schema registry is connected to the cluster to optimize space consumption and to potentially handle more easily any change to the structure of the data sources. This registry is a repository that manages and validates the schemas used in the system, in this case, the schemas of the source database.
The first part of this document covers the analysis of the requirements put forward by the company while also focusing on the design decisions that arose from the constraints and the challenges that the test environment presented.
The second part is dedicated to the detailed description of the main components of the infrastructure.
The third part is dedicated to the actual deployment of the environment with Ansible and how this approach led to a much more efficient deploying process that can be managed more easily compared to a manual one. Furthermore, the same environment was deployed as an ensemble of containers, showing this approach’s challenges and constraints while delving into the pros and cons of each method.
The final part of the document covers the feedback received from the company and what improvements might be necessary to use the cluster in production
Variations on the Author
Get PDF“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
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
