Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Three Years of Human Milk Banking: Assessing the Impact on Lactation Rates at Discharge in VLBW Preterm Infants in an Italian Reference NICU
Background: Human milk (HM) offers critical short- and long-term benefits for preterm and very low birth weight (VLBW) infants. In 2021, a human milk bank (HMB) was established at the IRCCS Giannina Gaslini Institute, aiming to improve HM feeding rates in this vulnerable population. Methods: We retrospectively analyzed feeding data from 442 VLBW infants (BW < 1500 g) admitted between 2018 and 2024. Data were drawn from the Vermont Oxford Network and Italian Neonatal Network registries. Feeding modalities—exclusive HM, infant formula milk (IM), and mixed feeding (MF)—were recorded and analyzed before and after HMB introduction. Results: Before 2021, MF was predominant, with exclusive HM rates below 10%. Following HMB implementation, exclusive HM feeding increased significantly, reaching 47.2% in 2024 (p < 0.0001). Regression analysis showed a positive trend for HM (+4.84%/year, p = 0.05), and a declining trend for IM (−1.96%/year) and MF (−2.88%/year). Projections suggest HM rates may exceed 58% by 2030. Conclusions: The introduction of the HMB was associated with a significant shift in feeding practices, increasing HM use and reducing IM exposure among VLBW infants. These findings underscore the importance of institutional strategies such as donor milk availability, lactation support, and maternal education in optimizing neonatal nutrition. Ongoing efforts are essential to sustain and extend these improvements beyond NICU discharge, ensuring the long-term benefits of human milk for preterm infants
A retrospective analysis of the occurrence of accidents during 20 years of neonatal transport in Liguria region, Italy
Our article focuses on a retrospective analysis of the occurrence of accidents relating to 20 years of activity of Neonatal Emergency Transport Service (NETS) in Liguria region, Italy. The objective of this study is to determine the vehicle accident rate for a specialized emergency medical services-NETS transport system between 1995 and 2015. We reviewed 5035 medical records related to the activity of our NETS from its beginning, in February 1995 to June 2015. We identified the occurrence of three road accidents (rate ∼1: 1600 transports; 1: 170 000 driven km), no helicopter accidents and only one technical problem during helicopter use; our service was not involved in any crashes resulting in injury. We discussed some reasons possibly explaining these good results

Lymphatic dysplasias in newborns and children: the role of lymphoscintigraphy
We performed lymphoscintigraphy in 15 patients (newborns and children) affected by congenital lymphatic dysplasia. We suggest that lymphoscintigraphy is mandatory in all patients with signs of lymphatic dysplasia, including those with minimal and initial signs of lymphatic impairment, to obtain very early diagnosis and begin treatment
Variations on the Author
“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
We 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
We 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
