However, current dual-task tests appear to be insufficient for early diagnosi…
Pactola kuscheli sp. nov. (Coleoptera: Curculionidae), a potential cause for the decline of the threatened New Caledonian conifer, Agathis montana de…
2017
Agathis montana is a conifer endemic to New Caledonia and one of the most threatened (Critically Endangered) plant species of this area. The exact causes of its decline are still unknown. The authors describe the characteristics of A. montana, the history and methodology of populatio nmonitoring, and possible factors causing the decline and habitat degradation. In 2014, some twigs showing symptoms suggesting attack by wood-boring insects were collected. From these, imagines of an unknown weevil species belonging to the genus Pactola Pascoe (Eugnomini)were reared. The new species is described as Pactola kuscheli Mazur sp. nov.

I fattori di rischio per la biodiversità forestale in Sicilia: il caso studio del cerro di Gussone
2011
Il cerro di Gussone (Quercus Gussonei (Borzì) Brullo) è una specie endemica della Sicilia esclusiva della catena dei Nebrodi e del bosco della Ficuzza. Il presente studio ha esaminato la rinnovazione di questa pianta, nella Riserva Naturale Orientata “Bosco della Ficuzza, Rocca Busambra, Bosco del Cappelliere, Gorgo del Drago”. Si tratta di una formazione boschiva monoplana che mostra chiari segni di deperimento. Per isolare i fattori che influenzano la rinnovazione e la crescita delle giovani piantine è stato eseguito un piano di trattamenti. Il risultato dello studio ha confermato che la rinnovazione si afferma in parte e, soprattutto, le giovani piantine non si accrescono a causa della p…

Sex-specific signatures of intrinsic hippocampal networks and regional integrity underlying cognitive status in multiple sclerosis
2021
Abstract The hippocampus is an anatomically compartmentalized structure embedded in highly wired networks that are essential for cognitive functions. The hippocampal vulnerability has been postulated in acute and chronic neuroinflammation in multiple sclerosis, while the patterns of occurring inflammation, neurodegeneration or compensation have not yet been described. Besides focal damage to hippocampal tissue, network disruption is an important contributor to cognitive decline in multiple sclerosis patients. We postulate sex-specific trajectories in hippocampal network reorganization and regional integrity and address their relationship to markers of neuroinflammation, cognitive/memory per…
Elaborazione e validazione di modelli dell’impatto antropico e dei cambiamenti climatici sulle qualità dei suoli in Sicilia, con particolare attenzio…
Il declino della sostanza organica e l’erosione idrica sono due fattori di rischio di degrado del suolo fra i più diffusi in Sicilia. In che misura è possibile contrastarli modificando le attività antropiche ed in particolare quelle in ambito agricolo? Lo scopo della presente ricerca di dottorato è stato quello di mettere a punto dei modelli che permettessero di spiegare le relazioni esistenti fra le azioni dell’uomo in ambito agricolo con la sostanza organica e con l’erosione idrica nei suoli siciliani, tenendo conto anche del clima. Le due indagini sono state svolte separatamente, in parallelo, in aree agricole della Sicilia occidentale per la sostanza organica, sull’intero territorio sic…
Production and Efficiency in 21 Industrialized Countries from 1966 to 2007 to Analyse the Italy’s Decline: Application of a Stochastic Frontier Model…
2008
This paper uses a stochastic frontier production model to estimate the technical efficiency of 21 nations among the more industrialized countries in the world for the wide period from 1966 to 2007. A Cobb-Douglas with labour and capital as inputs, GDP as output and efficiency with exponential distribution appears to work good from a statistical point of view. This model is used to estimate in a bayesian approach the efficiency score of these 21 countries. The bayesian way, applied via Gibbs sampling, is here useful to avoid problems about the small number of observations. So, each efficiency score is obtained as mean of 10,000 draws. The results underline a general and progressive efficienc…
Loneliness in adult people: its relationships with stress, health and hypothalamic-pituitary-adrenal axis functioning
2022
El sentiment de solitud és un dels principals problemes de les societats occidentals. En els últims anys els avanços en internet ens han portat a ser una societat més connectada que mai, a pesar d’açò, aquest sentiment s’està incrementant. Per sobreviure i prosperar, els éssers humans necessitem dels altres per satisfer les necessitats d’afecte, pertinença i reconeixement. D’aquesta manera, la solitud sorgeix de la discrepància entre les relacions íntimes i socials desitjades i les reals. La investigació indica que la solitud està relacionada amb l’estrès i amb diverses conseqüències en la salut tant física com psicològica. Aquesta es pot experimentar al llarg de la vida, encara que és més …

Alarmist by bad design: Strongly popularized unsubstantiated claims undermine credibility of conservation science
2019
“Unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades.” or “Our work reveals dramatic rates of decline that may lead to the extinction of 40% of the world's insect species over the next few decades.” These are verbatim conclusions of the recent paper by Sánchez-Bayoa and Wyckhuys (2019) in Biological Conservation. Because of fundamental methodological flaws, their conclusions are unsubstantiated. Like noted by The Guardian, the conclusions of the paper were set out in unusually forceful terms for a peer-reviewed scientific paper. The current case…
