Ri-mediare la politica. Gli utenti di Internet e l’influenza personale nella Campagna per le Politiche 2006
No full textQuesto studio si interroga sul ruolo di Internet nei processi di circolazione dell’informazione politico-elettorale e di influenza durante la Campagna per le elezioni politiche del 2006.
L’obiettivo è contribuire al superamento di una concezione ipersemplificata dell’utenza di Internet, proponendone un profilo più complesso sulla base della qualità e frequenza delle attività politiche online e delle attività influenti. L’analisi è partita dall’individuazione di differenti tipi di utenti del web politico, distinguendo i soggetti che usano la Rete esclusivamente come fonte di informazione politico-elettorale da coloro che, attraverso i nuovi ambienti “2.0”, producono contenuti politici, diventando essi stessi fonte e moltiplicatori dell’informazione politica verso gli altri internauti e verso i soggetti “non connessi”. Poiché l’esistenza di una ri-mediazione dell’informazione tra il messaggio mediale e la rete sociale non è una novità legata ad Internet, l’analisi si concentra su alcuni studi relativi alla mediazione individuale nei processi di influenza politica, a partire dalla ricerca pionieristica condotta da Lazarsfeld, Berelson e Gaudet (1948) sulla Campagna presidenziale statunitense del 1940. Si fa riferimento, inoltre, alle Revised Step-Flow Sequences elaborate da Robinson (1976) per evidenziare come il processo di raccolta, rielaborazione ed amplificazione dell’informazione assuma un’inedita portata euristica in un sistema mediale altamente complesso e frammentato come quello attuale. Più nello specifico, questo lavoro riprende le suggestioni di un’indagine dell’Institute for Politics Democracy & Internet (Ipdi), condotta durante le Presidenziali statunitensi del 2004, da cui emerge il ruolo strategico di alcuni utenti di Internet come nuovi opinion leaders politici.
Il contributo procede nella descrizione dell’ipotesi di un multi step-flow of communication model fornendo un profilo di quegli utenti di Internet che, durante la Campagna per le Politiche 2006, hanno utilizzando la Rete come database di informazioni, hanno veicolato l’informazione online verso chi non usa Internet, hanno rielaborato questa informazione, re-immettendola nel web attraverso vari sistemi di relazione socio-tecnologica e di partecipazione online.
I dati relativi agli utenti di Internet sono stati raccolti attraverso un questionario strutturato, somministrato via web nel mese precedente le Politiche del 2006, su 1990 lettori di quotidiani e periodici online.This contribution concerns the role of web users in the circulation of political-electoral information in the processes of influencing political opinion during the 2006 Campaign. This essay points out some conceptual and methodological suggestions in the studies on personal influence and tries to surpass the over-simplified view of political web users. The basic hypothesis is a more complex model of the online political communication flux: the multi-step flow of communication. Online information reaches some web users (Online Political Citizens Leaders) who then become sources of information and actors of re-mediation for people who don’t use this medium and for other Internet users characterised by a more generic and recreational use of the medium. The research has used a structured questionnaire completed online by 1.990 Internet users between March and April 2006
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
Leader d’opinione on-line nella campagna per le politiche 2006
No full textThis contribution concerns the role of the Internet and of the (techno)social networks in the circulation of political-electoral information and in the processes of influencing political opinion during the Campaign for the 2006 general elections in Italy. The study has used a structured questionnaire completed online by 1990 Internetusers between the 10th march and 9th April 2006. By aiming to reach a specific profile of Internet users, the link to the questionnaire has been activated only on online newspapers and periodicals with different political orientation.
In our research hypothesis, and relative operational definitions on the methodological level, we can identify four types of interviewed in the segment of Internet users we reached through the questionnaire: i) the Leaders (8,2% of the sample) who are influential towards the no-users thanks to the online information, but who are not engaged in political activities; ii) the Online Political Citizens Leaders (15,5%) who are online political activists and who have weaved a network of significant relationships with friends, colleagues and acquaintances, becoming for them a reference point on political themes. Their influence is exercised towards the political opinion of Internet users and no-users; iii) the Online Political Citizens Followers (23,2%) who are political activists engaged in online activities but who don’t exercise political influence; iv) the Peripherals (52,6%) who don’t carry out a very intense online political activity and who are not recognized in the role of political leaders. We have identified these four types of web users and described their profiles with the aim to i) surpass the over-simplified view of the political web users and ii) verify empirically the hypothesis of a more complex model of the flux of online political communication. The circulation of political information from the Internet develops, this is our suggestion, following the model of a multiple-steps flow of (political) communication. Thus, the characterization of the political opinion leaders, between the online newspapers and periodicals readers, during a political Campaign, is important on a theoretical level (by thinking a new perspective which doesn’t flatten out the critical exercise on interpretative models which are weaken by the complexity of the contemporary communication setting), but is also important for the communication action. The value of the political opinion leadership, held by the political web users during the electoral Campaign, requires the political communication professionals to address their online communication to some targets, the OPC Leaders and the Leaders, which are numerically narrow in comparison with television audiences, but are able to multiply information through a wide network of (techno)social relationships
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
