CONSERVATION STATUS ASSESSMENT OF THE ENDEMIC HIERACIUM S. STR. (ASTERACEAE) OCCURRING IN SICILY
2022
The current status of the majority of apomictic taxa, and therefore their priorities for conservation, are poorly known, and consequently, they are neglected by conservationists. In Sicily 8 species and 4 subspecies of Hieracium s. str. occurs. Eleven taxa are endemic to the area, one has a wider distribution. These taxa were not evaluated within the recent project “Red List assessment of plants and fungi in Italy” because collectively considered with insufficient and unreliable distribution data. The global conservation status of the endemic Hieracium s. str. taxa occurring in Sicily was assessed here using the IUCN categories and criteria, on the basis of the data collected during field s…
Personalità, minaccia e autoritarismo di destra.
2011
In un campione di 318 studenti di psicologia, abbiamo analizzato le relazioni fra «Big Five», minaccia sociale percepita proveniente dalla microcriminalità e dal terrorismo e autoritarismo di destra (RWA). Per entrambe le forme di minaccia, coerentemente con le nostre ipotesi, l'Apertura ha influenzato l'RWA, sia direttamente sia indirettamente, attraverso la mediazione della minaccia percepita, mentre la Coscienziosità ha influenzato l'RWA solo direttamente. L'interazione fra Apertura e minaccia proveniente dalla microcriminalità, ma non quella terroristica, ha influenzato significativamente l'RWA. L'articolo si conclude con una proposta di interpretazione di questo mancato effetto e il su…
Facing natural disasters through the endorsement of authoritarian attitudes
2020
Abstract We analyzed the relations between exposure to news describing a natural disaster and right-wing authoritarianism (RWA) with 241 Italian adults, surveyed twice, before and after a severe earthquake. Our results were compatible with the idea that the exposure to earthquake news led to an increase in RWA among people who had low, but not among who had relatively high, authoritarian levels before the event. We discuss the findings in terms of compensatory control, and highlight strengths and limitations of the study.
Societal Threat to Safety, Compensatory Control, and Right-Wing Authoritarianism
2014
We analyzed directly and indirectly the relationships between societal threat to safety, perceived control, and the increase in right-wing authoritarianism (RWA) in two studies. In Study 1 (national sample of the Italian population, N=1,169), we performed a longitudinal analysis structured into three waves (January 2003, September 2004, and January 2005). A moderated regression analysis showed that RWA increased from 2003 to 2005 as a function of perceived societal threat to safety more among low- than among high RWA scorers. In experimental Study 2 (Italian university students, N=131) a moderated mediation model showed loss of perceived control to mediate the relation between societal thre…
Believing in Hidden Plots is Associated with Decreased Behavioral Trust: Conspiracy Belief as Greater Sensitivity to Social Threat or Insensitivity T…
2022
Abstract Past research has demonstrated that conspiracy belief is linked to a low level of self-reported general trust. In four experimental online studies (total N = 1105) we examined whether this relationship translated into actual behavior. Specifically, since the decision to trust relies on the ability to detect potential social threat, we tested whether conspiracy believers are better at detecting actual threat, worse at detecting the absence of threat, or simply trust less, irrespective of any social cue. To this end, participants played multiple, independent rounds of the trust game, a behavioral measure for interpersonal trust. We manipulated social threat by presenting photographs …
Linderiella baetica Alonso & Garcia-de-Lomas 2009 (Crustacea, Branchiopoda, Anostraca): On the verge of extinction?
2016
The province of Cadiz (South of Spain) hosts the only known locality in the world of Linderiella baetica Alonso & Garcia-de-Lomas 2009 (Anostraca). In this paper, the geographical distribution of the species based on published sampling data focused on large branchiopods and temporary pools in Andalusia and the entire Iberian Peninsula is assessed. The current situation is summarized based on the threats to their survival, which are mainly related to habitat alteration. In the Iberian Peninsula, at least 1,648 bodies of water (about 720 in Andalusia) have been explored. Prevalence data suggest that L. baetica is a rare species (localities with presence / sample locations = 6.07 . 10-4). The …
Hibrīddraudu novēršana Latvijā, Zviedrijā un Spānijā
2022
Maģistra darbā "Hibrīddraudu novēršana Latvijā, Zviedrijā un Spānijā" tiek pētīti un salīdzināti hibrīddraudu novēršanas pasākumi Latvijā, Zviedrijā un Spānijā kopš 2014. gada (Krievijas hibrīdkara pret Ukrainu) līdz 2022. gadam (Krievijas pilna mēroga karadarbībai pret Ukrainu). Pētījumā tiek aplūkota dažādu faktoru ietekme uz starpvalstu sadarbības veidošanos hibrīddraudu novēršanas jomā, īpašu uzsvaru liekot uz atšķirīgiem plānošanas cikliem. Darba teorētisko ietvaru veido mūsdienu hibrīddraudu galveno izpausmju un to novēršanas iespēju apraksts. Balstoties uz teorētiskajām atziņām, tiek izvirzīti empīriskās izpētes kritēriji – visas valdības (whole-of-government) un visas sabiedrības (w…
Stereotype Threat Effect on a Simple Motor Task: An Investigation of the Visuo-Spatial Working Memory

Purpose: Based on the Chalabaev et al. (2013) study showing that in a Stereotype Threat (ST) situation the velocity of force production in a simple motor task can be affected, this study aimed to r...
Consensus in Noncooperative Dynamic Games: a Multi-Retailer Inventory Application
2008
We focus on Nash equilibria and Pareto optimal Nash equilibria for a finite horizon noncooperative dynamic game with a special structure of the stage cost. We study the existence of these solutions by proving that the game is a potential game. For the single-stage version of the game, we characterize the aforementioned solutions and derive a consensus protocol that makes the players converge to the unique Pareto optimal Nash equilibrium. Such an equilibrium guarantees the interests of the players and is also social optimal in the set of Nash equilibria. For the multistage version of the game, we present an algorithm that converges to Nash equilibria, unfortunately, not necessarily Pareto op…
Noncooperative dynamic games for inventory applications: A consensus approach
2008
We focus on a finite horizon noncooperative dynamic game where the stage cost of a single player associated to a decision is a monotonically nonincreasing function of the total number of players making the same decision. For the single-stage version of the game, we characterize Nash equilibria and derive a consensus protocol that makes the players converge to the unique Pareto optimal Nash equilibrium. Such an equilibrium guarantees the interests of the players and is also social optimal in the set of Nash equilibria. For the multi-stage version of the game, we present an algorithm that converges to Nash equilibria, unfortunately not necessarily Pareto optimal. The algorithm returns a seque…
