Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Prosódia de enunciados declarativos e interrogativos totais nas variedades de Salvador, Fortaleza e Rio de Janeiro
No full textResumo: Este trabalho tem como objetivo descrever diferenças entre variedades dialetais do português falado em Salvador, Fortaleza e Rio de Janeiro, Brasil, tanto nas sentenças declarativas quanto nas interrogativas. A análise de parâmetros prosódicos (frequência fundamental, duração, intensidade) é feita no núcleo final de sentenças oxítonas, paroxítonas e proparoxítonas. Há diferenças prosódicas sistemáticas entre as duas modalidades (declarativa e interrogativa): um tom alto ou subida de F0 no núcleo das interrogativas e, ao contrário, um tom baixo ou descida de F0 no núcleo das declarativas. Variações dialetais também são observadas. Os acentos tonais nucleares H + L*L% para as declarativas e L + H*L% para as interrogativas, propostos por Moraes (2008), são observados nos falantes do Rio de Janeiro – sendo este último truncado ou comprimido em sentenças oxítonas, devido à falta do material postônico. Entretanto, nas variedades de Salvador e Fortaleza, as interrogativas também podem ser realizadas com um padrão L + H*H%. Maior elisão de sílabas é observada nos falantes de Fortaleza. Palavras-chave: prosódia; entoação; sentenças declarativas; sentenças interrogativas totais; variação dialetal.Abstract: This work aims at describing differences between the dialectal varieties of Portuguese spoken at Salvador, Fortaleza and Rio de Janeiro, Brazil, in both the declarative and interrogative modalities. Analyses of prosodic parameters (fundamental frequency, duration, intensity) are made on the final nucleus of oxytonic, paroxytonic and proparoxytonic sentences. There are systematic prosodic changes between modalities – with a higher / rising F0 in interrogative nucleus where it is lower / decreasing for declaratives. The interrogative nucleus are also longer and stronger than the declaratives. Dialectal variations are also observed. The accentual patterns H + L*L% for declaratives and L + H*L% for interrogatives proposed by Moraes (2008) are observed in Rio de Janeiro speakers – the latter being truncated or compressed in oxytonic sentences due to lack of post-tonic material. Meanwhile, in the Salvador and Fortaleza varieties, interrogatives may also be performed with a L + H*H% pattern. More syllable elisions are also observed in Fortaleza speakers.Keywords: prosody; intonation; declarative sentences; yes/no questions; dialectal variation
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
Study of the structure, energetics, and vibrational properties of small ammonia clusters (NH3)n (n=2-5) using correlated ab initio methods
No full textEquilibrium geometries, interaction energies, and harmonic frequencies of (NH3)(n) isomers (n = 2-5) have been computed using correlated calculations (MP2) in conjunction with Dunning's aug-cc-pVXZ (X = D, T, Q) basis sets and the Counterpoise procedure. Whenever available, literature values for the binding energy and geometry of dimers and trimers agree well with our data. Low lying isomers for (NH3)(4) and (NH3)(5) have been found to have similar binding energies (roughly 16 and 20 kcal/mol for the tetramer and pentamer, respectively), perhaps suggesting the presence of a very smooth energy landscape. Using BSSE corrected forces or freezing the monomer structure to its gas phase geometry have been found to have only a weak impact on the energetic and structural properties of the clusters. The effect of zero-point energy (ZPE) on the relative stability of the clusters has been estimated using harmonic frequencies. The latter also highlighted the presence of vibrational fingerprints for the presence of double acceptor ammonia molecules. Many-body effects for (NH3)(n) isomers (n = 2-4) have been investigated to explore the possibility of building a pairwise interaction model for ammonia. In the frame of the work presented, we have found the 3-body effect to account for 10-15% of the total interaction energy, whereas the 4-body effects may be neglected as first approximation
