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
Politiche di contrasto al lavoro non dichiarato: punire, curare o prevenire?
No full textL’obiettivo di questo articolo è quello di valutare gli effetti relativi delle misure di dissuasione (deterrence), prevenzione, cura e impegno (commitment) sull’ampiezza del lavoro non dichiarato in Italia. A tal fine, inseriamo questo tipo di lavoro in un modello dinamico di equilibrio generale con produzione moonlighting, evasione fiscale e frizioni reali nel mercato del lavoro e lo calibriamo sull’economia italiana. Le politiche del primo tipo sono qui rappresentate dalle sanzioni inferte alle imprese colte ad utilizzare lavoro non dichiarato; il secondo approccio è incapsulato nelle politiche attive del mercato del lavoro volte a migliorare la produttività dei lavoratori dichiarati; le azioni curative sono esemplificate da riduzioni dell’aliquota fiscale sul lavoro e le politiche di commitment da misure in grado di influenzare la disapprovazione sociale (social stigma) del lavoro non dichiarato. Il principale risultato è che se tutti questi approcci riducono la quota media di output non dichiarato, le politiche di deterrence e di commitment generano anche effetti negativi sul reddito e sull’occupazione di lungo periodo. L’approccio basato sulle politiche attive del mercato del lavoro è quello da preferire, perché realizza la massima riduzione del lavoro non dichiarato, stimolando al contempo l’output e l’occupazione
Tackling Undeclared Work. Suggestions from a Business Cycle Model with Search Frictions.
No full textThe paper evaluates the relative effect of deterrence, prevention, curative and commitment policy measures on the size of undeclared work in a real business cycle model with undeclared work, tax evasion and search frictions in the labour market. A numerical application of the model to the European economy shows that all these approaches reduce the undeclared share of output, but that deterrence and commitment policies also produce a negative effect on stationary employment. The curative approach produces the sharper fall in undeclared work while stimulating stationary output and employment
The effects of monetary policy shocks in credit and labor markets with search and matching frictions
No full textBy introducing search and matching frictions in both the labor and the credit markets into a cash in advance New Keynesian DSGE model, we provide a novel explanation of the incomplete pass-through from policy rates to loan rates. We show that this phenomenon is ineradicable if banks possess some power in the bargaining over the loan rate of interest, if the cost of posting job vacancies is positive and if firms and bank sustain costs when searching for lines of credit and when posting credit vacancies, respectively. We also show that the presence of credit market frictions moderates the reactions of output and wages to a monetary shock, and that the transmission of monetary policy shocks to output and inflation is more relevant than suggested by the recent literature
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
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
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
