The Paracentrotus lividus metallothionein gene family: structure and expression.
2014
Metallothioneins are metal binding proteins that play a pivotal role in metal homeostasis and detoxification. Since their initial discovery, they have been extensively studied in a variety of organisms ranging from microbes to plants and animals. Organisms often possess multiple genes encoding metallothionein homologs with distinct properties, such as varying affinities for different metals, and in many cases different functions. Despite the plethora of available studies, very little information is known about sea urchin P. lividus MT (1, 2). We previously identified five Pl-MT embryonic cDNAs and we studied their induction after cadmium treatment (3). Now we studied their expression during…

Enhancing the user authentication process with colour memory cues
2022
The authentication process is the first line of defence against potential impostors, and therefore is an important concern when protecting personal and organisational data. Although there are many options to authenticate digital users, passwords remain the most common authentication mechanism. However, with password numbers increasing, many users struggle with remembering multiple passwords, which affects their security behaviour. Previous researchers and practitioners have attempted to suggest ways to improve password memorability and security simultaneously. We introduce novel approach that utilises colour as a memory cue to increase password memorability and security. A longitudinal stud…
Testing the Modified Sediment Delivery Model (MOSEDD) at SPA2 Experimental Basin, Sicily (Italy)
2017
A new version of a spatially distributed sediment delivery model taking into account the hillslope sediment transport efficiency, named MOSEDD, is presented. This model gives estimates of basin sediment yield at event scale, which are more reliable than those obtained by the original SEDD. For SPA2 basin discretized into morphological units, four different calculation schemes of MOSEDD, including the original SEDD version, were applied. All parameterization schemes of the model were calibrated using 15 events measured at the outlet of the experimental basin in the period February 2005–February 2010. The model calibration was used to determine a relationship between the coefficient βe of the…
Innovative In Situ and Ex Situ Conservation Strategies of the Madonie Fir Abies nebrodensis
2022
Abies nebrodensis (Lojac.) Mattei is an endemic species of the north-west of Sicily located in an 84 ha area in the Madonie Regional park. The current population is limited to 30 relic adult trees and a fluctuating number of juveniles of natural regeneration. The species is defined as “Critically Endangered” in the Italian list of threatened plants and is classified as CR-D in the 2000 IUCN Red List of Threatened Species. This article reports the key action undertaken by the LIFE4FIR project aimed at preserving A. nebrodensis, and the results obtained so far in three years of activity. OpenArrays SNPs genotyping revealed a high rate of inbreeding in the natural population and that the adult…

Girls4STEM: Gender Diversity in STEM for a Sustainable Future
2020
Science, Technology, Engineering, and Mathematics (STEM) are key disciplines towards tackling the challenges related to the Sustainable Development Goals. However, evidence shows that women are enrolling in these disciplines in a smaller percentage than men, especially in Engineering related fields. As stated by the United Nations Women section, increasing the number of women studying and working in STEM fields is fundamental towards achieving better solutions to the global challenges, since the potential for innovation is larger. In this paper, we present the Girls4STEM project, which started in 2019 at the Escola Tè
Emotional Profile and Intellectual Functioning
2015
Insufficient literature has been produced addressing children with borderline intellectual functioning (BIF) and gifted intellectual functioning (GIF). The goal of this work is to compare levels of self-esteem, depression, anxiety at school, and insecurity among children with BIF and GIF, and a control group of average intellectual functioning (AIF). There were participants of 104 children (fourth grade of primary school). Analyses revealed that children with BIF showed a lower level of self-esteem and higher levels of depression and school anxiety. Moreover, our findings highlight the co-occurrence of school anxiety, depressed mood, and insecurity among the BIF and AIF groups. One of the …
Self-esteem and intentions mediate perceived fitness with physical activity in Finnish adolescents with long-term illness or disabilities
2014
Background: The International Classification of Functioning, Disability and Health (ICF) is recognised as the common language in disability research. However, personal factors in the ICF are not explicitly coded because of cultural differences that influence physical activity (PA) participation. The ICF suggests using fitness as a personal factor, as well as other psychological assets. Intentions may serve as such psychological assets and studies on the antecedents to intentions which prompts PA behaviours is lacking in adolescent long term illness or disability (LTID) populations. Objective: The purpose of this study was to report how ICF personal factors can influence participation in PA.…
Prosociality and life satisfaction: A daily-diary investigation among Spanish university students
2018
Abstract With a diary study, we tested the positive effect of prosociality on life satisfaction. Fifty-six Spanish undergraduate students (45 females; Mage = 21.08 years) rated their life satisfaction, prosociality, self-esteem, and physical appearance for 5 consecutive days. Multilevel results indicated that within-individual positive deviations in prosociality (i.e., behaving more prosocial than usual) were uniquely and significantly associated with higher life satisfaction on that specific day. Students' self-esteem, physical appearance, and positive daily events were also predictive of life satisfaction. Exploratory analyses revealed that the positive effect of prosociality on life sati…
