Phosphorus Coordination Chemistry: A Special Issue in Honor of Maurizio Peruzzini.
No full textThe present Article Collection celebrates the
outstanding scientific career of Maurizio
Peruzzini and his interest in Phosphorus
Chemistry. Maurizio was formed as a young
chemist at the University of Florence (Italy)
under the supervision of Piero Stoppioni
and Claudio Bianchini, thus belonging to
the numerous heirs of the prestigious chemistry
school of Luigi Sacconi. After a period
as research assistant at the same University,
in 1986 he won a place as researcher at
CNR-ISSECC, now CNR-ICCOM, where Maurizio
spent most of his further activity as scientist. Since the beginning,
he got fascinated by the beauty and complexity of main group
and transition metal coordination chemistry, in particular phosphorus
in all its allotropic forms. This interest accompanied him
throughout his scientific career, that saw promotions first to Senior
Researcher (1996–2001) and then to Research Director (2001–
2020). In 2013 he became Director of CNR-ICCOM, after two years
as Deputy Director, and in 2017 he took the position of Director of
the CNR Department of Chemical Sciences and Materials Technology
in Rome, until retirement in 2020. Since then, Maurizio has
taken the role of Senior Associate at CNR-ICCOM, and still actively
collaborates with his coworkers in various fields of research. His
commitment to the development of chemistry in Italy brought
him to become President of the Inorganic Chemistry Division of
the Italian Chemical Society (2009–2011). He was the mentor of
many undergraduate, postgraduate students and postdoctoral
fellows coming from all over the world to join his research group
in Florence. Maurizio’s bibliometric data are truly outstanding,
with more than 400 co-authored peer-reviewed papers, more
than 13,000 citations and an h-index of 57 (WoS data, 14th April
2021)

Novel Coordination Polymers Based on Bis- and Tris-pyrazolyl Ligands
No full textSeveral pyrazole-based ligands of both rigid and flexible nature have been exploited for the preparation of multifunctional coordination polymers with assorted dimensionality (from 1D to 3D) through either conventional synthetic procedures or solvothermal routes. They were found to display permanent microporosity and remarkable thermal resistance. They were successfully exploited for CO2 adsorption and as solid-state photoluminescence materials
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
