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
Public debt, inequality and economic growth
Full text linkThe project aims to bring attention to wealth inequality, an aspect often neglected in empirical analyses due to a lack of adequate data. Taking advantage of recent advances, particularly for the United States, I extended a study traditionally focused on income distribution to the link between public debt and wealth inequality. Considering the strong link between wealth and public debt, mediated by government bonds and portfolio choices, I explored the interdependence between these two phenomena.
For the analysis, I used the VEC model, which allows us to examine both short- and long-run dynamics, testing causality and transmission mechanisms between variables. Moreover, since there was no suitable package in R for this type of analysis, I developed a specific tool. A chapter of the project was dedicated to the description of the package: structure, main functionalities and comparison with other existing tools.
The results of the analysis show that there is a link from public debt to wealth inequality, but not the other way around. However, indirect forms of interdependence emerge through fiscal policy choices. Moreover, the long-run relationship between public debt and inequality proves to be significant, profoundly influencing the latter.
A second empirical study, conducted as part of the project, focused on two objectives: analysing the impact of income distribution on economic growth; investigating the impact of debt distribution on the distribution of income; and analysing the impact of debt distribution on the distribution of wealth.
The results show that inequality within the three segments into which the income distribution was divided has a negative impact on growth. In contrast, inequality between the segments has a positive effect. The whole inequality. Overall inequality, on the other hand, impacts negatively on the income growth of the poorer population, and positively on the richer population
Alla ricerca della bilateralità nel territorio: gli enti nel panorama toscano
No full textIl saggio esamina il ruolo degli enti bilaterali alla luce della riforma del mercato del lavoro del 2003 (legge n. 30/2003 e art.2, lett. h), d. lgs. n.276/2003) con particolare attenzione all'esperienza regionale toscana. L'insieme dei compiti assegnati agli enti bilaterali (funzioni di intermediazione, di formazione, anche con ricorso a risorse pubbliche, nonché di certificazione e amministrazione delle relative controversie) sono analizzati alla luce di innovative esperienze territoriali. L’occasione di questo studio è fornita dalle informazioni e dai dati messi insieme nel corso del 2005 presso alcuni degli enti bilaterali toscani (EBRET, EBTT, EBCT, CERT) nei rispettivi settori di pertinenza (artigianato, turismo, commercio e terziario, edilizia) e sulla specifica area artigiana ed edile della provincia di Siena (CIA e Cassa edile della provincia di Siena). Quest’ultimo percorso ha messo in luce un importante esperimento di mutualizzazione di oneri contrattuali e di organizzazione sociale del welfare in un microlaboratorio provinciale a bassa densità industriale
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
Contrattazione collettiva e area contrattuale
No full textLa riflessione prende le mosse dal controverso concetto di categoria professionale (art. 2070 c.c.; art. 39, c. 4 Cost.), passando per modelli molto diversi ma contigui – come il settore di attività per i datori di lavoro ai fini previdenziali ed assistenziali (es. art. 49, l. n. 88/1989), quello previsto per la fiscalizzazione degli oneri sociali e per gli sgravi contributivi (es. art. 8, l. n. 407/1990, oggi abrogato da art. 1, commi 118-124, l. n. 190/2014; art. 3, d.l. n. 71/1993 sostituito dall’art. 10, l. n. 30/2003), quello per i benefici accordati dallo Stato e per l’appalto di opere pubbliche (art. 36, l. n. 300/1970; art. 118, comm 6, d. lgs. 163/2006) ed infine il sistema di classificazione delle attività economiche (codice Ateco 2007 per le rilevazioni Istat; Circ. Inps n. 80 del 25 giugno 2014) – per giungere ad analizzare il campo oggettivo di applicazione del contratto collettivo nazionale (ccnl).
I sindacati e le contrapposte associazioni di rappresentanza datoriale sono i soggetti legittimati ad individuare la platea di destinatari della disciplina collettiva: la parola categoria può essere intesa come attività merceologica (es.: il settore attività industria e la classe di attività metalmeccanica) o come ambito professionale dell’organizzazione sindacale (es.: federazione dei lavoratori della conoscenza). Premesso che non sempre l’area merceologica corrisponde a quella sindacale e che più contratti nazionali possono essere siglati per lo stesso settore (Corte Cost. 26 marzo 2015, n. 51), la determinazione della categoria diventa centrale per stabilire il perimetro o meglio l’ambito di misurazione delle condizioni rappresentative che legittimano la partecipazione negoziale e la sottoscrizione del relativo contratto
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
Urban poverty: Measurement theory and evidence from American cities
Full text linkWe characterize axiomatically a new index of urban poverty that i) captures aspects of the incidence and distribution of poverty across neighborhoods of a city, ii) is related to the Gini index and iii) is consistent with empirical evidence that living in a high poverty neighborhood is detrimental for many dimensions of residents’ well-being. Widely adopted measures of urban poverty, such as the concentrated poverty index, may violate some of the desirable properties we outline. Furthermore, we show that changes of urban poverty within the same city are additively decomposable into the contribution of demographic, convergence, re-ranking and spatial effects. We collect new evidence of heterogeneous patterns and trends of urban poverty across American metro areas over the last 35 years
