Multiple normalized solutions for a Sobolev critical Schrödinger-Poisson-Slater equation
2021
We look for solutions to the Schr\"{o}dinger-Poisson-Slater equation $$- \Delta u + \lambda u - \gamma (|x|^{-1} * |u|^2) u - a |u|^{p-2}u = 0 \quad \text{in} \quad \mathbb{R}^3, $$ which satisfy \begin{equation*} \int_{\mathbb{R}^3}|u|^2 \, dx = c \end{equation*} for some prescribed $c>0$. Here $ u \in H^1(\mathbb{R}^3)$, $\gamma \in \mathbb{R},$ $ a \in \mathbb{R}$ and $p \in (\frac{10}{3}, 6]$. When $\gamma >0$ and $a > 0$, both in the Sobolev subcritical case $p \in (\frac{10}{3}, 6)$ and in the Sobolev critical case $p=6$, we show that there exists a $c_1>0$ such that, for any $c \in (0,c_1)$, the equation admits two solutions $u_c^+$ and $u_c^-$ which can be characterized respectively…
Quasisymmetric spheres over Jordan domains
2015
Let $\Omega$ be a planar Jordan domain. We consider double-dome-like surfaces $\Sigma$ defined by graphs of functions of $dist( \cdot ,\partial \Omega)$ over $\Omega$. The goal is to find the right conditions on the geometry of the base $\Omega$ and the growth of the height so that $\Sigma$ is a quasisphere, or quasisymmetric to $\mathbb{S}^2$. An internal uniform chord-arc condition on the constant distance sets to $\partial \Omega$, coupled with a mild growth condition on the height, gives a close-to-sharp answer. Our method also produces new examples of quasispheres in $\mathbb{R}^n$, for any $n\ge 3$.
Perturbations of the derivative along periodic orbits
2006
International audience; We show that a periodic orbit of large period of a diffeomorphism or flow, either admits a dominated splitting of a prescribed strength, or can be turned into a sink or a source by a C1-small perturbation along the orbit. As a consequence we show that the linear Poincaré flow of a C1-vector field admits a dominated splitting over any robustly transitive set.
Psicodinamiche di convivenza nel gruppo di lavoro: un'indagine esplorativa
2009
Psicodinamiche di convivenza nel gruppo di lavoro: un'indagine esplorativa - This work is focused on the study of psychodynamics of cohabitation in work groups, organizations and institutions. The generic aim is to explore the relations between organizational feelings and work group efficacy. The research has been carried out with a group of 120 Sicilian workers. In the present study we considered organizational commitment, justice, trust and power feeling. The multiple correspondence analysis point out two dimensions called: Collusion/Collusion Failed and Adhesive Professional Identity/Repulsive Professional Identity. The results point out relations between middle scores of organizational …
Relationships Between Organizational Justice and Burnout at the Work-Unit Level.
2005
Relationships between organizational justice and well-being are traditionally investigated at the individual level. This article extends previous efforts by testing such relationships at the work-unit level. Three corridors of influence were examined. First, the level (work units’ average scores) of justice is related to the level of burnout. Second, justice climate strength (level of agreement among work-unit members) moderates the predictability of the level of burnout. Third, justice strength is related to burnout strength. The authors interviewed 324 contact employees from 108 work units in 59 service organizations. Findings showed the predominance of interactional justice over distribu…
Self-reported playing time and justice as predictors of coach satisfaction: An analysis of elite ice-hockey and handball players
2020
Intrateam competition for specific roles and playing time is a continuous imperative process in elite sport teams. The assessment of this competition is done by the coach and the outcome of this process has a significant impact on the team and the players. The following hypothesis was put forward for testing: Self-reported playing time and perceptions of justice among elite ice-hockey and handball players predict their satisfaction with the coach. Elite ice-hockey and handball players (N = 231) reported playing time and completed the Perceived Justice and Athlete Satisfaction Questionnaires. Hierarchical multiple regression analyses show that self-reported playing time, distributive justice…
A future of journalism beyond the objectivity-dialogue divide? : Hybridity in the news of entrepreneurial journalists
2019
As pioneers of new ideas and practices, many entrepreneurial journalists spearhead the change of journalism towards hybridity. By applying appraisal theory, this article examines a hybrid of objectivity and dialogue in daily news articles by five entrepreneurial journalism outlets – Axios, MustRead, National Observer, The Skimm and the Voice of San Diego. For comparative purposes, a dataset from three legacy media outlets was also analysed. The results show that the entrepreneurial journalism outlets employ journalistic dialogue in otherwise stylistically objective news texts notably more often than do legacy media outlets. Dialogic registers provide subtle, non-partisan assessments of eve…
Ma‘dûle Önermelerde Varlıksal İçerik Sorunu: Fahreddin er-Râzî-Kutbüddin et-Tahtânî Tartışması
2019
This paper addresses discussions in post-Avicennan Arabic logic on the definition of metathetic propositions and their status in relation to existential import requirements, focusing on the arguments made by Fakhr al-Dīn al-Rāzī (d. 606/1210) and the counter-arguments by Quṭb al-Dīn al-Rāzī al-Taḥtānī (d. 766/1365), who both establish their positions in the framework drawn by the most prominent figure in the tradition of classical Arabic logic, Avicenna (Ibn Sīnā, d. 428/1037). In the latter’s works, the problem of the existential import requirement in metathetic propositions (ma‘dūla) are thoroughly discussed and Avicenna seems to have presumed the existential import as a truth-condition f…
