Bethe-Salpeter treatment of Λ, ∑ resonances under harmonic confinement
No full textThe unequal-quark-mass problem of excited Λ, ∑ states is treated through a multichannel generalization of a relativistic Bethe-Salpeter treatment of the simpler (equal mass) problem of N, Λ as well as meson states, recently found to give excellent fits to the corresponding spectra. The present fits to the Λ, ∑ masses are fully in tune with the quality of the NL, ΛL results, as evidenced by the highly consistent values of the appropriate universal function F(M) representing the central (mass)2 for each N-supermultiplet, calculated with the same reduced spring constant and quark masses as employed earlier for NL, ΛL and meson states
Isotope shift studies of the B<SUP>3</SUP>∑<SUP>-</SUP>-X<SUP>3</SUP>∑<SUP>-</SUP> bands of SO
No full textThe B3∑--X3∑- bands of SO were excited in an electrodeless microwave (2450 Mc/s) discharge through trace amounts of sulphur enriched with 37% of 34S and oxygen enriched with about 40% of 18O. The emission spectra of 32S16O, 34S16O and 32S18O were photographed on a Jarrell-Ash 3.4 m. grating spectrograph at a dispersion of 5Å/mm. Isotope shift data obtained from the present studies support the revision of the earlier vibrational scheme (Henri and Wolff, 1929; Martin, 1932) by increasing v"-quantum numbering by two units as suggested by Norrish and Oldershaw (1959)
The d<SUP>1</SUP>∑<SUP>+</SUP>-c<SUP>1</SUP>Π system of NH
No full textThe singlet systems of NH have been excited in a mildly condensed transformer discharge through flowing ammonia gas. The 0-0 bands, 2530Å of d1∑+-c1Π and 3240Å of c1Π-a1Δ systems, appear with considerable intensity compared to the 4502Å band of the c1Π-b1∑+ system. Besides the 2530Å bands, two weaker bands at 2683Å and 2516Å are also excited. They are photographed in the second order of a Jarrell Ash 3.4 m. grating spectrograph at a dispersion of 2.6Å/mm. Rotational analysis of the two weaker bands show that they belong to the d1∑+-c1Π system and further supports their assignment as the 0–1 and 1-1 bands
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
Overlap integrals of BeO (B<SUP>1</SUP>∑→X<SUP>1</SUP>∑) system by approximate analytic methods
No full textThe overlap integrals of the bands of BeO (BlE →X1∑) system are calculated by both the approximate and the later improved approximate analytic methods given by Fraser and Jarmain e), Jarmain and Fraser7), and Fraser 8) and the values compared with the derivations obtained from the more direct method of numerical integration involving Morse oscillator functions. The results of the improved approximate method give excellent agreement with those from the numerical integration procedure. A good deal of labour involved in the. use of the latter method viz., numerical integration is saved by adopting the improved analytic method which can therefore be profitably used for the calculation of overlap integrals
Variations on the Author
No full text“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
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
