Strong Instability of Ground States to a Fourth Order Schrödinger Equation
2019
Abstract In this note, we prove the instability by blow-up of the ground state solutions for a class of fourth order Schrödinger equations. This extends the first rigorous results on blowing-up solutions for the biharmonic nonlinear Schrödinger due to Boulenger and Lenzmann [8] and confirm numerical conjectures from [1–3, 11].

Natura e alterita: ancora sull'Aria del Tasso di Giuseppe Tartini:
2014
La passione di Giuseppe Tartini per la musica popolare è attestata da quattro versioni per violino dell’Aria del Tasso. L’Aria rientra nell’ambito di una nuova poetica che ricerca la verità nei canti di natura. Come i musicografi della generazione successiva, il violinista attribuisce alla semplicità un ruolo paradigmatico per separare il concetto di natura dal concetto di artificio. Per cui, il semplice canto di popolo, assieme alla musica greca del periodo classico e alla musica delle «nazioni» non evolute, è più vicino allo stato primigenio, ossia allo stato di natura e quindi alla verità. A questo problema si collegano tre fasi del pensiero del trattatista, in cui il termine natura subi…

Shallow Sea Gas Manifestations in the Aegean Sea (Greece) as Natural Analogs to Study Ocean Acidification: First Catalog and Geochemical Characteriza…
2022
The concepts of CO2 emission, global warming, climate change, and their environmental impacts are of utmost importance for the understanding and protection of the ecosystems. Among the natural sources of gases into the atmosphere, the contribution of geogenic sources plays a crucial role. However, while subaerial emissions are widely studied, submarine outgassing is not yet well understood. In this study, we review and catalog 122 literature and unpublished data of submarine emissions distributed in ten coastal areas of the Aegean Sea. This catalog includes descriptions of the degassing vents through in situ observations, their chemical and isotopic compositions, and flux estimations. Tempe…
Eco-Anxiety, Connectedness to Nature & Green Equity Investments
2023
International audience; Drawing on a survey of 671 French individual investors, we document for the first time the connection between emotions towards the environment and investment in green funds. Both eco-anxiety and connectedness to nature have a significant impact on deciding to invest in green funds, but, interestingly, do not exert any influence on the amount invested. Hence, investing in green funds seems to be a way to buy a good conscience towards the environment, but the good deed ends there since the amount itself is not linked to environmentally related emotions.
Agroecological engineering
2015
Earth has recently entered the new era of the Anthropocene, during which the rise of human activities are impacting for the first time ecosystems and climate on the global scale. Since the 1960s the green revolution has improved food production in quantity using industrially-designed agriculture, which has led to global pollution by pesticides and losses of food quality, biodiversity and soil carbon. As a consequence there is a need to implement agroecological practices in order to produce food safely and in a sustainable way. This virtual issue presents principles and applications of agroecological engineering, exemplified in 19 selected review articles from the journal Agronomy for Sustai…
Jürgen Habermas and the risk of liberal eugenics for the ethical self-understanding of species
2016
El artículo analiza el problema de la naturaleza humana que presenta Jürgen Habermas en su obra El futuro de la naturaleza humana, ¿Hacia una eugenesia liberal? Los vertiginosos avances biotecnológicos reclaman una rigurosa reflexión bioética que el filósofo alemán afronta superponiendo a su ética del discurso una ética de la especie. Habermas esboza un modelo de naturaleza humana construido sobre preceptos como la dignidad humana y de la vida humana, la simetría de las relaciones intersubjetivas y, a resultas de estas, la autocomprensión ética de la especie. Respecto a la eugenesia liberal, el autor se posiciona criticando la eugenesia positiva y amparando la negativa, para lo que basa su …

[On the presence of Erctella mazzullii (De Cristofori & Jan, 1832) (Gastropoda: Helicidae) in the Nature Reserve of Isola delle Femmine (Palermo, Sicily, Italy)] The presence of a living population of Erctella mazzullii (De Cristofori & Jan, 1832) (Gastropoda: Helicidae), endemic species of the coastal strip of the Palermo Mountains (Sicily), from Isola delle Femmine or Isola di Fuori (Isola delle Femmine Nature Reserve) is confirmed
Arruolare la natura in Erodoto
2018
The study identifies the roles assigned by Herodotus to natural and environmental elements in war events, or in general conflictual events. These elements are considered as cooperators of justice by virtue of law according to which men and the local natural environment constitute a complex of mutually supportive parts and even in a concrete relationship of mutual aid. They also appear as spaces characterized in a merely dimensional sense. Here the Greek «smallness» is functional to the impossibility of containing the number of the Persian army which, therefore, can only be defeated.
