Guidelines for the census and monitoring of macromycetes
According to the FFF initiative (Fauna Flora Funga), fungi should be recognized as playing a crucial role in ecosystem functioning. Therefore, it is time to include fungi in the global conservation goals. The fungal kingdom is equally as important as the animal and plant kingdoms for the understanding of our planet, and fungi are key for interpreting the functioning and resilience of ecosystems.
There is a growing public consciousness of the role of fungi in the environment and the necessity to conserve them and their habitats.
Recording mycological data is important to improve local and national distribution maps of fungi. High quality data also allows the comparison of past and present findings to understand the changes in biodiversity that have occurred over time. In addition, reliable data for local and national Red Lists emphasizes the mycological value of sites that may be subject to planning applications.
In Italy, there are numerous mycological groups and associations that record local fungi around the country. There are also many mycologists who work independently in the field. Consequently, there is a large dataset representing an invaluable resource with enormous potential.
However, until now, each mycologist or group has been using their own collection and registration rules and standards. Establishing and sharing common protocols for collection has therefore become essential.
In 2020, the Italian Institute for Environmental Protection and Research ISPRA (Istituto Superiore per la Protezione e la Ricerca Ambientale) developed a Network for the study of mycological diversity.
One of the most important initiatives of the Network is the “National collecting of fungi”. Its first goal is to collect fungal data in a national database, the “Fungi Information System” (SIF, Sistema Informativo Funghi), encouraging mycologists, experts, and groups to record their local findings in a systematic format and submit them to the SIF. The database will include not only edible fungi but all fungal species that may be indicators of habitat quality.
This is the first national initiative that aims to collect data from different sources, sent autonomously and voluntarily, so that Italy has a database to help policy makers to include fungi in national and regional legislation.
It is in this context that these guidelines have been proposed. Starting from the basic principles of collection, to providing instructions for sending mycological and habitat data to the Network, the recording procedures have been established with the main objective of sharing them with stakeholders at all levels.
To carry out future conservation actions we need data on a nation-wide scale, so let’s start

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
