L’exemplum del Dinomenide Gelone tra memoria civica e storiografica
2015
La storia della Sicilia greca è scandita, nei suoi momenti chiave, dalla persistente presenza dell’immagine del Dinomenide Gelone. Questo lavoro analizza le valenze paradigmatiche assunte dalla sua figura nella memoria civica siracusana e nella produzione storiografica; inoltre ricostruisce le dinamiche politiche che hanno spinto i principali tiranni siracusani (da Dionisio I a Ierone II) a stabilire un confronto con Gelone. Il suo exemplum è utilizzato per legittimare azioni politiche e impegno antipunico; particolare attenzione è posta alla Biblioteca storica di Diodoro Siculo e al ruolo che in essa assume la figura del Dinomenide; in relazione a questi aspetti l’opera dell’Agirinense sem…
Tra idealità e progetto. La politica democratica e il suo oltre
2022
The article examines the foundations of democracy, showing the link between ethics and politics, between political action and the spiritual dimension. It also focuses on the difference between the individualistic political model and the community model
Cognitive vulnerability to depressive symptoms in children: the protective role of self-efficacy beliefs in a multi-wave longitudinal study.
2014
The current multi-wave longitudinal study on childhood examined the role that social and academic self-efficacy beliefs and cognitive vulnerabilities play in predicting depressive symptoms in response to elevations in idiographic stressors. Children (N = 554; males: 51.4 %) attending second and third grade completed measures of depressive symptoms, negative cognitive styles, negative life events, and academic and social self-efficacy beliefs at four time-points over 6 months. Results showed that high levels of academic and social self-efficacy beliefs predicted lower levels of depressive symptoms, whereas negative cognitive styles about consequences predicted higher depression. Furthermore,…
Cultural and psychological variables predicting academic dishonesty: a cross-sectional study in nine countries
2021
Academic dishonesty has serious consequences for human lives, social values, and economy. The main aim of the study was to explore a model of relations between personal and cultural variables and academic dishonesty. The participants in the study were N = 2,586 individuals from nine countries (Pakistan, Israel, Italy, India, the USA, Peru, Romania, Ghana, and Poland). The authors administered the Academic Dishonesty Scale to measure academic dishonesty, the Kessler Psychological Distress Scale to measure distress, the Almost Perfect Scale – Revised to measure perfectionism, the Brief Self-Control Scale to measure self-control, and the Singelis Scale to measure independent self-construal. Th…
The Effects of Short-Term Personal Goals on Subjective Well-Being
2015
Several studies demonstrated that subjective well-being is associated with goal value and perceived progress but their validity is affected by methodological biases. Moreover, a few have analysed the influence of short-term goals. We aimed to analyse how the levels of and changes in short-term goals progress and value influence subsequent levels of and changes in subjective well-being. This study adopted a three-wave longitudinal design with one-month intervals. Four hundred nine participants (186 males; age 19–71) reported their subjective well-being and their two most important goals and rated each over time in terms of value and progress. A latent difference score model revealed that lev…
Common fixed points of generalized Mizoguchi-Takahashi type contractions in partial metric spaces
2015
We give some common fixed point results for multivalued mappings in the setting of complete partial metric spaces. Our theorems extend and complement analogous results in the existing literature on metric and partial metric spaces. Finally, we provide an example to illustrate the new theory.

The purpose of this paper is to provide stochastic versions of several results on fixed point theorems in the literature.

2011
Recently, Huang and Zhang [\emph{Cone metric spaces and fixed point theorems of contractive mappings}, J. Math. Anal. Appl., \textbf{332} (2007), 1468 -1476] defined cone metric spaces by substituing an order normed space for the real numbers and proved some fixed point theorems. Let $E$ be a real Hausdorff topological vector space and $P$ a cone in $E$ with int\,$P\neq \emptyset$, where int\,$P$ denotes the interior of $P$. Let $X$ be a nonempty set. A function $d : X \times X\to E$ is called a \emph{tvs}-cone metric and $(X, d)$ is called a \emph{tvs}-cone metric space, if the following conditions hold: (1) $\theta \leq d(x, y)$ for all $x, y \in X$ and $d(x, y)= \theta$ if and only if $x…
