No full textGoing 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
Il professionista proattivo. Il ruolo delle convinzioni progettuali sul modo di intendere l’inclusione
Full text linkL’intento di questo contributo è quello di evidenziare l’importanza della
competenza progettuale nella sfida di promuovere la piena realizzazione
dell’inclusione delle persone disabili adulte. Tale finalità è perseguita avviando
un focus sul ruolo delle convinzioni sulla progettazione dei professionisti che si
prendono cura del futuro delle persone disabili, e come suddette convinzioni si
relazionino con le loro credenze relative alla possibilità di includere realmente.
Infatti il processo di inclusione, come si vedrà nei paragrafi successivi, richiede
una visione progettuale lunga, articolata e analitica: è fondamentale sostenere
la prospettiva inclusiva con determinazione e padronanza metodologica,
per non scivolare in riduzionismi
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
La valutazione come apprendimento o formante. Una prospettiva-guida per il Garante del Progetto di vita.
Full text linkQuesto contributo delinea alcune riflessioni sulla figura professionale del
Garante del Progetto di vita (d’ora in poi solo Garante), ideato dalla Fondazione
Dopo di Noi di Bologna. La prospettiva di analisi offerta da questo capitolo
è prettamente metodologica. La finalità non è dunque approfondire gli aspetti
più inerenti ai processi inclusivi che tale figura intende promuovere, quanto
quella di mettere in luce la prospettiva metodologica che può supportarli o dirigerli.
La panoramica oggetto di questo focus è quella valutativa, strettamente
collegata a quella progettuale. La scelta di optare per una riflessione di questo
tipo nasce dalle inevitabili suggestioni derivanti dal nome di questa professione
e dalla centralità delle azioni, prevalentemente valutative, che il Garante deve
mettere in atto
Water:values,rights,territory,business and governance
No full textThe question of water aspect of becoming a matter of modern society world poses serious questions about the key strategies of sustainable development in an intra-and inter-generational perspective. In March 2009 and held at the Istanbul the 5th Water World Forum and presented data from a UN report showed that 8 million people die from water scarcity; it is estimated that 1.1 billion people lack access to water resources, 2.6 billion people have health and hygiene problems, 3900 children are victims every day for water shortage. The pressure of population cause unstoppable pollution of groundwater and watercourses. In 2030 there is the risk that the half world population remains without adequate levels of water resources. J. Maynard Keynes in an article in 1932 "Exhortations and Prophecies" poses to public attention the fact that global development has been marked by excessive limits of scarcity of one of the production factors. Until the end of the 19th century limiting factor has always been represented by the capital. In 20th century the factor that has begun to limit of development so more and more decisive natural and environmental resources. Between natural resources that affected the evolution is just the water. The paper try to analyzes and answer a several critical question. The main arguments analyzed in the paper are: the shortage, the pressure on consumption due to increasing world population, the unbalanced use across sectors and between the intra and civil society, the use of water as an instrument of geopolitical pressure, the right of access and the legal character of the water good
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
