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
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
Impatto della struttura proprietaria sulle performance di una giovane impresa high tech : rilevanza dei costi di agenzia orizzontali
No full textLAUREA MAGISTRALEIl progresso tecnologico è sempre più considerato come una delle forze fondamentali, in grado di alimentare le dinamiche di sviluppo del sistema economico globale. Partendo da questa evidenza, un’ampia letteratura economica si è focalizzata sull’apporto dato all’economia da una particolare tipologia di imprese, le New Technology Based Firm (NTBF). Le NTBF sono start-up, operanti in settori high-tech, il cui business consiste nella commercializzazione dei risultati del progresso tecnologico. Molteplici autori hanno evidenziato l’importanza delle NTBF come motore primario della crescita occupazionale e veicolo principale attraverso cui le innovazioni tecnologiche radicali irrompono sul mercato.
Queste, però, sono imprese che, per via della giovane età e dell’importante attività di R&S di cui necessitano, si trovano a dover fronteggiare importanti vincoli finanziari e di competenze. Questi vincoli, se non opportunamente colmati, possono pregiudicarne la crescita e in alcuni casi anche la sopravvivenza. Diventa quindi di primaria importanza la raccolta di risorse esterne per mezzo delle quali colmare tali gap che, altrimenti, potrebbero inibire a cascata la crescita economica.
L’elevata difficoltà per i finanziatori esterni nel comprendere l’effettiva qualità dell’impresa, però, fa sì che nelle NTBF risulti più problematico attrarre capitali esterni, rispetto che nelle altre imprese. In particolare risulta problematico l’accesso al capitale di debito per via della scarsa dotazione di risorse tangibili da utilizzare come collaterale e dell’elevata specificità degli asset. Il modo più semplice per allargare la dotazione di risorse e competenze, quindi, è quello di ampliare l’azionariato, aprendo il capitale sociale a nuovi investitori.
In questo lavoro di tesi si intende valutare qual è l’impatto sulle performance d’impresa di un nuovo socio a fronte del suo ingresso nel capitale sociale dell’impresa. Vengono identificate tre tipologie di investitori (i.e. insider, outsider, venture capitalist) e il relativo impatto sulle performance viene valutato tenendo conto di due fattori contrastanti. Da un lato l’effetto positivo legato all’apporto di nuove risorse in linea con quanto detto dalla Resource Based View (RBV), dall’altro quello negativo dato dai costi di agenzia orizzontali che l’ingresso di un investitore esterno produce. Vengono inoltre esplorati i meccanismi di controllo in grado di inibire i costi di agenzia orizzontali focalizzandosi in particolare modo sul ruolo moderatore del debito e della concentrazione proprietaria.
Le analisi econometriche sono state effettuate su un campione di 273 NTBF italiane estratto dal dataset RITA, per mezzo di due scremature successive. In prima istanza sono state eliminate tutte le osservazioni per le quali su RITA non si disponevano di dati di bilancio. Successivamente sono state eliminate tutte le osservazioni per le quali non erano disponibili informazioni sui soci attuali e sui trasferimenti di quote anno per anno sul registro della Camera di Commercio (TELEMACO).
I risultati delle verifiche empiriche evidenziano un impatto positivo sulle performance del venture capitalist e un impatto non significativo dei soci operativi. Per quanto riguarda invece gli outsider, emerge un impatto negativo sulle performance che diventa positivo a fronte dell’effetto moderatore dei costi di agenzia prodotto dal capitale di debito e dalla concentrazione della struttura proprietaria.Technological progress is increasingly seen as one of the most important driver of dynamic development of the global economic system. Starting from this evidence, a large economic literature has focused on their contribution to economy of a particular type of venture, the New Technology Based Firm (NTBF). NTBF are start-up, operating in high-tech sectors through the marketing of the results of their R&D activities. Several authors has underlined the importance of NTBF as primary engine of occupational growth e as principle vehicle for radical technology innovation.
These firms, due to their early age and the R&D activities they need, can suffer from financial and competence constraints. These constraints, if not properly filled up, can not to allow them to pursue growth strategies and even threaten their survival. It is therefore of prime importance the raising of external resources by which filling these gaps that might otherwise inhibit economic growth. The high trouble for external investors to understand the actual quality of the company, however, means that the NTBFs will be more difficult to attract outside capital, than in other businesses. Particularly problematic is the access to debt financing because of the lack of tangible resources as collateral and high asset specificity. So, the easiest way to expand the endowment of resources and skills, is to open the capital to new investors.
The aim of this work is to evaluate what is the impact on firm performance of a new investor after its entrance into the capital of the company. It has been identified three types of investors (i.e. insiders, outsiders, venture capitalists) and their impact on performance is evaluated taking into account two opposing factors. On the one hand the positive effect of providing new resources in line with the Resource Based View (RBV), the other negative do to horizontal agency costs that a new investor produces.
It also explored the control mechanisms to inhibit the horizontal agency costs, focusing in particular on the moderator role of debt and ownership concentration.
The econometric analyzes were performed on a sample of 273 Italian NTBFs extracted from the dataset RITA, whereby two successive skimmings. In the first instance it has been eliminated observations for which weren’t available balance sheet data. It has been then eliminated all observations for which weren’t available information on the current members and transfers of shares each year on the register of the Italian Chamber of Commerce (TELEMACO).
The results of empirical tests show a positive impact on the performance of the venture capitalist and a non significant impact of the enlargement of insiders team. As for outsiders, empirical test shows a negative impact on performance, which becomes positive when the firm is higly levered or concentrated confirming the moderator role of bank debt and concentration of ownership structure
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.
