Modelling range dynamics of terricolous lichens of the genus Peltigera in the Alps under a climate change scenario
No full textClimate change is expected to strongly impact biodiversity in Alpine ecosystems and species distribution modelling is increasingly used to provide anticipatory information to guide conservation. In this study, (1) we quantified the range loss, range gain, range change and range turnover caused by climate change in the genus Peltigera a group of terricolous lichens widespread across the Alps, and then (2) we evaluated the relationships between the predictors of range dynamics and functional traits. Our results indicate moderate range dynamics for species of the genus Peltigera across the Alps under a climate change scenario. This would imply a relative stability and resistance of these lichens to climate change that may reflect the local persistence of the species under sub-optimal conditions. Our results also suggest that range dynamics could be associated with functional traits mainly related to water-use strategies and to a trade-off between dispersal and establishment ability. This finding suggests that functional traits may strongly modulate the lichen response to climate change and that species with similar functional traits are prone to similar selective pressures
Reti e stili di attaccamento in relazione all'adattamento psicologico di giovani adulti
No full textMolti autori hanno ipotizzato e, in parte, verificato una relazione fra stili di attaccamento e adattamento dell’individuo. In particolare, si ritiene che i diversi stili di attaccamento giochino un ruolo nella regolazione affettiva del soggetto e che alcune strategie insicure di attaccamento, per la loro valenza difensiva e per la rigidità, possano promuovere un cattivo adattamento (Del Corno, Capriotti & Puricelli, 2007). Recentemente, Kobak et al. (2007) hanno avanzato l’ipotesi che anche la composizione delle gerarchie di attaccamento e la modalità con cui avviene il trasferimento delle funzioni di attaccamento al di fuori della famiglia, oltre che lo stile di attaccamento, influenzino l’adattamento della persona, in particolare in adolescenza. La presente ricerca aveva l’obiettivo di verificare se alcuni aspetti dell’adattamento individuale (ansia, manifestazioni depressive e disforiche e stress psicologico) sono in relazione con gli stili di attaccamento e con la struttura della rete di attaccamento di cui dispone il soggetto giovane adulto.
METODO. Alla ricerca hanno partecipato 100 giovani adulti (50 femmine, 50 maschi; età: 19-30 anni), ai quali sono stati somministrati i seguenti strumenti: (1) Il questionario Attachment Network Questionnaire-Revised (ANQ-R; Doherty & Feeney, 2004; Calvo & de Romano, 2008), per la valutazione della rete di attaccamento e delle figure di attaccamento preferite dal soggetto; (2) Il questionario Experiences in Close Relationships-Revised (ECR-R; Fraley, Waller, & Brennan, 2000) per la valutazione dell’attaccamento adulto nelle relazioni sentimentali; (3) lo State-Trait Anxiety Inventory Forma Y (STAI-Y), per la valutazione dell’ansia di stato e di tratto; (4) Il Questionario D (QD in Batteria CBA-2.0 Scale primarie; Sanavio et al., 1997), per rilevare la presenza di manifestazioni depressive e disforiche; (5) il test M.S.P. (Mesure du Stress Psychologique; Lemyre, Tessier & Fillion, 1990; Di Nuovo et al., 2000) per la valutazione dello stato di stress.
RISULTATI. I risultati preliminari hanno evidenziato alcune relazioni significative fra le caratteristiche della rete di attaccamento del soggetto, lo stile di attaccamento adulto, valutato in termini di evitamento e di ansia riguardo all’attaccamento, e alcune delle dimensioni di adattamento considerate nello studio

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
The Dolichens database: the lichen biota of the Dolomites
Full text linkThe Dolichens project provides the first dynamic inventory of the lichens of the Dolomites (Eastern Alps, Italy). Occurrence records were retrieved from published and grey literature, reviewed herbaria, unpublished records collected by the authors, and new sampling campaigns, covering a period from 1820 to 2022. Currently, the dataset contains 56,251 records, referring to 1,719 infrageneric taxa, reported from 1820 to 2022, from hilly to nival belts, and corresponding to about half of the species known for the whole Alpine chain. Amongst them, 98% are georeferenced, although most of them were georeferenced a posteriori. The dataset is available through the Global Biodiversity Information Facility (GBIF; https://www.gbif.org/es/dataset/cea3ee2c-1ff1-4f8e-bb37-a99600cb4134) and through the Dolichens website (https://italic.units.it/dolichens/). We expect that this open floristic inventory will contribute to tracking the lichen diversity of the Dolomites over the past 200 years, and providing the basis for future taxonomic, biogeographical, and ecological studies
