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
Il costo dell'AIDS: le indicazioni di uno studio pilota
No full textAccanto ai problemi sanitari, assistenziali ed etici, l'AIDS rappresenta un grosso problema anche dal punto di vista economico. Non tanto per le risorse che oggi assorbe, ma per quelle che con ogni probabilità potrà assorbire nel prossimo futuro, quando gli attuali sieropositivi saranno diventati dei veri malati di AIDS. Il volume, accanto ad una rassegna critica della letteratura specializzata in materia, contiene i risultati di uno studio pilota volto a chiarire gli aspetti metodologici propri di un'indagine diretta a stimare il costo del trattamento ospedaliero di un paziente con AIDS conclamato.
Più che nelle stime di costo cui perviene, l'importanza del volume risiede dunque nella serie di indicazioni di metodo fornite per sapere quale può essere la spesa necessaria a fronteggiare la nuova domanda di servizi. Quali, di conseguenza, le modalità terapeutiche più convenienti per l'intera collettività (cioè meno costose a parità di risultati), da adottare nei confronti di tali ammalati
OSA (Optical Society of America) Journal of Optical Networking - Special issue: Call for Papers: Optical Networks for the Future Internet
No full textIn the past 30 years the Internet has been very successful while developing through an incremental
approach. The evolution of the Internet’s popularity has led to its current central
position as a fundamental enabler of the world’s economy. Several developments have allowed
the Internet to adjust to this evolving role, and one of the fundamental drivers has been
the wide availability of broadband connections based on optical transmission technologies.
However, there are many challenges to be foreseen as driving forces to redefine the Internet.
The traffic demand is increasing exponentially due to the growing number of users and offered
bandwidth per user as well as the large data flows that are transferred between users.
In addition, an enormous increase in on-line content offered by the Internet is expected to
continue. These network scaling requirements, both in terms of number of users, their devices,
and bandwidth are key facets of the future Internet that has not been fully explored
anywhere and will potentially require major contributions from the photonics research community.
The existing Internet was not originally designed to scale to billions of users and to
the multi-Gbits/s transmission rates to the desktop that will be found in future applications
supporting computational data, sensor grids, digital cinema, storage, etc.
This special issue will solicit contributions discussing the most significant aspects that
will position optical technologies as a fundamental contributor in defining the future Internet
architecture. Some of these aspects will be scalability, programmability, parallelism, network
adaptations, and network management.
The scope of the papers includes, but is not limited to, the following topics:
• Scalable optical network architectures for the future Internet
• Optical network security, reliability, survivability, and quality of service provisioning
• Optical network architectures supporting future Internet applications
• User control of network infrastructure and services
• New service paradigms
• Internet routing architectures supporting future optical networks
• Energy- and cost-efficient optical network
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
