La Medea di Pier Paolo Pasolini
No full textIl lavoro intende essere una riflessione complessiva sul mito di Medea, inserito nell’articolato percorso ideologico di Pier Paolo Pasolini. Allegoria della società contemporanea, la Medea pasoliniana, incentrata sull’impossibilità dell’amore tra Medea (Maria Callas) e Giasone (l’atleta Giuseppe Gentile), ossia sull’inconciliabilità di due mondi, quello barbaro, arcaico e religioso, cui appartiene la donna, e quello razionale, moderno e laico, a cui afferisce Giasone, esprime la visione «apocalittica» dell’ultimo Pasolini. L’autore assiste impotente e atterrito all’affermazione di una modernità desacralizzata, che fa dell’edonismo consumistico e della sua inesorabile forza omologante il proprio elemento connotativo e totalizzante. Medea, oltraggiosamente rifiutata, riaffermerà se stessa compiendo, al contempo, il suo annientamento, per cui nel finale, su cui incombe un’assoluta cupezza, non le resterà che gridare: «È inutile. Niente è più possibile, ormai»
Structural Ordering of Molybdenum Disulfide Studied via Reactive Molecular Dynamics Simulations
No full textMolybdenum disulfide
(MoS2) is a well-known and effective lubricant that provides
extremely low values of coefficient of friction. It is known that
the sliding process may induce structural transformations of amorphous
or disordered MoS2 to the crystalline phase with basal
planes oriented parallel to the sliding direction, which is optimal
for reducing friction. However, the key reaction parameters and conditions
promoting this structural transformation are still largely unknown.
We investigate, by employing reactive molecular dynamics simulations,
the formation of MoS2 layers from an amorphous phase as
a function of temperature, initial sample density, and sliding velocity.
We show that the formation of ordered crystalline structures can be
explained in the framework of classical nucleation theory as it predicts
the conditions for their nucleation and growth. These results may
have important implications in the fields of coating and thin-film
deposition, tribology, and in all technological applications where
a fast and effective structural transition to an ordered phase is
needed
Deumanizzazione del paziente oncologico nei contesti medici
No full textIn this paper the authors explore the presence of infrahumanization effects when the target is cancer patients. Participants were physicians and nurses working in cancer institutes or oncology departments of hospitals. Participants were asked to judge their own category and that of cancer patients on a set of traits. Uniquely human (e.g., rationality, reasoning) and non-uniquely human traits (e.g., impulse, instinct) were used. Patients were also judged on traits expressing the essence of human nature, such as emotionality and relational capacities. The denial of traits of human nature leads to a type of dehumanization, that is called mechanistic dehumanization. Findings show that both physicians and nurses assign the unique features of human category less to patients than to health professionals (infrahu-manization effect). In contrast, effects of mechanistic dehumanization were not revealed. In the discussion, the authors examine the potential consequences of cancer patients' infrahumanization on the therapeutic relationship and treatment effectiveness
Evaluating the Effects of a Message on Attitude and Intention To Eat Raw Meat: Salmonellosis Prevention
No full textSalmonellosis is one of the most common foodborne human diseases. The risk of infection can be reduced by communication campaigns. The aim of this study was to demonstrate the efficacy of a food safety message that underlines that eating well-cooked meat is an effective strategy for preventing salmonellosis. The target audience was young adults (university students). They were presented with one of two messages, a prevention message or a control message. The prevention message proved to be very effective. First, it changed the attitude toward raw or rare meat, which after having read the prevention message was evaluated less positively and more negatively. Second, intentions to eat raw or rare meat were weaker in those who read the prevention message compared with those who read the control message. Third, after the message, participants in the experimental condition, but not in the control condition, associated the self-image more with well-done meat than with raw or rare meat

From intergroup contact to outgroup humanization: The mediational role of intergroup threat
No full textOld and Novel Enteric Parvoviruses of Dogs
No full textParvovirus infections have been well known for around 100 years in domestic carnivores. However, the use of molecular assays and metagenomic approaches for virus discovery and characterization has led to the detection of novel parvovirus species and/or variants in dogs. Although some evidence suggests that these emerging canine parvoviruses may act as primary causative agents or as synergistic pathogens in the diseases of domestic carnivores, several aspects regarding epidemiology and virus-host interaction remain to be elucidated
