Il trattamento di /w/ in posizione iniziale in italiano è influenzato dall'ortografia? Indizi dalla selezione dell'articolo maschile
No full textItalian native speakers show two patterns concerning the selection of the singular masculine definite article allomorph before a glide /w/ or a sibilant + glide cluster /sw/. As far as Italian native lexemes are concerned, speakers select l' and il before /w/ and /sw/, respectively. Differently, il and lo are selected before loanwords showing the same contexts in first position. We propose that the observed divergence is due to two syllabifications of the phonemic strings including a glide /w/. In turn, the different syllabifications depend on the graphemic representation of the glide: in the native lexicon, mostly in loanwords. It is thus proposed that the vocalic versus consonantal status of the grapheme representing the glide influences the phonological representation of the glide itself. If /w/ is written as , it occupies a nuclear position, if /w/ is written as , it stands in onset position. We conducted an analysis on the vast Google Books corpus to corroborate this view. Moreover, a phonological analysis of Italian diphthongs is discussed
The metathesis in the dialect of Suelli (CA): A descriptive analysis of the rhotic consonant
No full textThe paper aims at providing phonetic grounds to support the idea of Campidanese metathetic aberrant clusters (mr, sr, tsr, tʃr) as branching onsets. A phonological interpretation is presented, followed by the phonetic analysis of the rhotic consonant in marked clusters recurring in the dialect of Suelli (Campidanese Sardinian group). In spite of their intrinsic articulatory complexity, such clusters do not show acoustic differences as compared to cross-linguistically unmarked consonant clusters. Our analysis is focused on the rhotic consonant: its phonetic behaviour in such clusters is compared to that of /r/ in unmarked clusters and intervocalic environment. In particular, we looked for patterns analogous to those found in literature concerning marked clusters of the Campidanese typology. The analysis is based on fieldwork data and has showed that no particular acoustic pattern is at work when aberrant clusters are concerned. It will be claimed that the cross-linguistically systematic presence of a vowel portion preceding taps in Cr clusters and the high number of rhotic variants do not have phonological relevance in determining the syllabic status of Campidanese aberrant clusters
Criteri metodologici per la valutazione dell’efficienza del processo di stabilizzazione dei rifiuti
No full textAl fine di valutare l'efficacia di ricette di stabilizzazione condotte sui differenti tipologie di rifiuti, in termini di diminuzione della lisciviabilità degli inquinanti, sono state messe a punto particolari procedure di Bilancio di Materia. Le procedure sono raccolte e tradotte in calcoli, grazie all’impiego di macro su fogli Excel®, che forniscono il giudizio finale espresso come “Stabilizzazione %”. Il risultato ottenuto misura l’efficacia del processo di trattamento effettuato, valutando la diminuzione o l’aumento (nel caso di processi non efficaci) delle quantità relative di inquinanti lisciviati. La procedura confronta i risultati ottenuti nei test di cessione sui materiali stabilizzati con i risultati al test di cessione sui singoli rifiuti non trattati, opportunamente corretti per la diluizione che i singoli rifiuti hanno ricevuto nella miscela finale. Il metodo si presta per la valutazione della stabilizzazione anche in processi in cui due o più rifiuti sono miscelati tra loro
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
