Banca Dati Nazionale sugli Spiaggiamenti di Cetacei - National Marine Mammal Strandings Data Bank
No full textLa raccolta sistematica di informazioni sugli spiaggiamenti di mammiferi marini sulle coste italiane è iniziata nel 1986 grazie a una rete nazionale di osservatori per tenere sotto controllo le coste e intervenire nel caso di animali spiaggiati per effettuare il riconoscimento delle specie, prelevare campioni di tessuti, o l'intero corpo, per necessità di studi sulle cause della morte o sulla specie in questione. Per molti anni gli animali spiaggiati hanno rappresentato una importante fonte di informazioni scientifiche e di reperti per i musei italiani. Attualmente l'interesse e' maggiormente concentrato sulle problematiche sanitarie, sullo studio delle cause di morte, sull'analisi dei contaminanti chimici, e sull'analisi genetica dei reprti prelevati. Dal 2007, per volere del Ministero dell'Ambiente e su richeista di ACCOBAMS, tutti i dati raccolti sono messi online a disposizione di tutti gli studiosi. La BDS fornisce un quadro storico e sempre aggiornato degli spiaggiamenti sulle coste italiane anche ai fini della conoscenza della distribuzione delle specie e dell'impatto delle attività umane sui mammiferi marini e l'ambiente marino in generale (ad esempio tramite l'analisi dei contaminanti accumulati da questi animali)
Freely faceted classification for the BioAcoustic Reference Database.
No full textThe Integrative Level Classification (ILC) research project is experimenting with a knowledge organization
system based on phenomena rather than disciplines. Each phenomenon has a constant notation, which can be
combined with that of any other phenomenon in a freely faceted structure. Citation order can express
differential focality of the facets. Very specific subjects can have long classmarks, although their complexity
is reduced by various devices. Freely faceted classification is being tested by indexing a corpus of about
3300 papers in the interdisciplinary domain of bioacoustics. The subjects of these papers often include
phenomena from a wide variety of integrative levels (mechanical waves, animals, behaviour, vessels,
fishing, law...) as well as information about the methods of study, as predicted in the León Manifesto. The
archive is recorded in a MySQL database, and can be fed and searched through PHP Web interfaces
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
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
