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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Miglioramento del Controllo di Processo in una linea di Converting tissue di Essity S.p.A
No full textIl lavoro di tesi affronta un progetto di miglioramento continuo svolto durante il tirocinio presso il reparto di converting di Essity Italia S.p.A., multinazionale leader nel settore cartario. L’obiettivo è stato quello di curare l’implementazione di un sistema software per la raccolta automatica e continua dei parametri di processo della ribobinatrice di una linea di converting tissue, precedentemente riportati su semplici fogli cartacei. Tale progetto ha rappresentato un punto di apertura verso Industria 4.0 e ha consentito di implementare un primo passo verso il controllo statistico di processo.
Fin da subito sono stati riscontrati dei vantaggi legati al massiccio numero di valori acquisiti che hanno aiutato a identificare le cause base dei principali fermi macchina non pianificati, a ridurre i difetti qualitativi del prodotto e a intervenire preventivamente sul processo prima del verificarsi di irreparabili guasti meccanici.
L’elaborato offrirà una panoramica sull’azienda e sul processo produttivo per poi descrivere il sistema e le fasi per la sua implementazione e concludere con una rassegna di principali utilizzi e proposte di miglioramento per assumere un maggiore e più efficace controllo del processo.
The thesis work is about a continuous improvement project carried out during the internship at the converting department of Essity Italy S.p.A., a multinational, leader in the paper sector. The goal was to implement a software system for the automatic and continuous collection of the process parameters of the rewinder of a tissue converting line, previously reported on simple paper sheets. This represented a step towards Industry 4.0 and allowed the project to implement a first step towards statistical process control.
Advantages linked to the acquired values were immediately found, which included the main identification of the basic causes of unplanned machine downtime, to reduce product defects and to intervene on the process before irreparable mechanical failures occur.
The paper will offer an overview of the company and the production process and then will describe the system and the phases for its implementation and will conclude with a review of the main uses and suggestions for improvement to assume greater and more effective control of the process
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
La Balanced Scorecard come strumento per il raggiungimento dei risultati strategici: il caso Meoni e Bartoletti
No full textIl lavoro, coordinato dall’Ing. Manfredi, si è sviluppato tramite uno stage effettuato presso Meoni e Bartoletti, azienda di sub-fornitura del settore automotive. Lo stage si è svolto tramite affiancamento a due responsabili di funzione aziendale (qualità e industrializzazione). La prima parte del lavoro riguarda l’esplicitazione della strategia aziendale, l’individuazione e misura di alcuni indicatori compresa l’integrazione del sistema di gestione e monitoraggio attuale (costituito sul modello Iso 9001), con un approccio più “inclusivo” di tutte le attività, basato sulla Balanced Scorecard. In questo contesto, la prima attività è stata quella di identificare i principi strategici su cui si fonda l’organizzazione per costruire la Mappa Strategica con le 4 prospettive e sono stati individuati per ogni prospettiva gli indicatori di performance (alcuni già definiti del sistema di gestione attuale, altri aggiunti e misurati). La seconda parte è stata più operativa sviluppando a) l’analisi dei costi di lavorazione allo scopo di misurare indicatori di efficienza, b) partecipando alla realizzazione di un sistema di monitoraggio e registrazione dei parametri di uno dei processi aziendali per la qualificazione e documentazione del processo stesso. In questo modo ho contribuito a rendere visibile e di concreta percezione la connessione tra la strategia e le azioni conseguenti
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
