Resource sharing optimality in WiFi infrastructure networks
2009
In WiFi networks, mobile nodes compete for accessing a shared channel by means of a random access protocol called Distributed Coordination Function (DCF). Although this protocol is in principle fair, since all the stations have the same probability to transmit on the channel, it has been shown that unfair behaviors may emerge in actual networking scenarios. Assuming that a contending node can dynamically change its strategy, by tuning its contention parameters to non-standard values on the basis of channel observations, we prove that, for infrastructure networks with bidirectional traffic and homogeneous application requirements, selfish access strategies are able to reach equilibrium condi…
Demographic change, tourism expenditure and life cycle behavior
2015
Abstract The paper explores how demographic changes in human populations may impact on tourism decision-making of households over their life cycle. By means of hurdle models, the study focuses respectively on the decision to travel domestically or abroad and investigates if statistically significant differences exist as to the impact of age and cohort on the decision to travel and tourism expenditure. Using a vast dataset on Italian Household Expenditures over the period 1997–2007 the empirical results show that demographic aspects do have a strong effect on the tourism behaviour of families and that cohort and age effects act differently on the decision of households to make a trip and on …

Costruzioni discorsive sull’Europa e sui rapporti tra continenti nell’antichità greca
2019
L’articolo studia le retoriche cui sono state sottoposte le identità rappresentate dai continenti. Viene mostrato così che la mitica parentela originaria ha dato luogo ora ad un legame di solidarietà tra i popoli che occupano l’una o l’altra zona geografica, ora ad una giustificazione delle pretese imperialistiche di un popolo su un altro. Si mostra altresì che i confini tra i continenti vengono presentati, a seconda del punto di vista difensivo o aggressivo da cui se ne parla, ora come segni di una ‘architettura’ naturale di cui si pretende il rispetto, ora come ostacoli da superare in nome dell’amore della conoscenza che vuole esplorare l’ignoto o dell’addomesticamento di ciò che è selvag…

Lower cortisol response in high-resilient caregivers of people with autism: the role of anger
2016
Caring for an offspring with an autism spectrum disorder (ASD) has been related to high stress levels and health disturbances. However, a protective effect against these negative health outcomes has been described in high-resilient caregivers. In this context, the main aim of the present study was to assess the association between resilient coping and cortisol response to acute stress in caregivers of people with ASD. Furthermore, the study aimed to explore the mediating role of anger in this association. We exposed 40 caregivers of people with ASD to an acute psychosocial stressor in the laboratory. Salivary cortisol samples were obtained before, during, and after the stressor. Resilient c…
ESTRÉS Y AFRONTAMIENTO EN FAMILIAS DE HIJOS CON TRASTORNO DE ESPECTRO AUTISTA
2016
Abstract.Research shows the relationship between having children with neurodevelopmental disorders and family stress. The Autism Spectrum Disorder or ASD has its own symptoms and a number of additional problems that give it a distinctive profile. These differences are reflected in the levels of stress shown by caregivers of children with the disorder. Coping is a reaction to behavioral and / or psychological stress, aimed at reducing the destructive stress attributes. Theories of stress and coping, as well as more specific models of family accommodation show how coping strategies have an important role in the outcome of adaptation. Consequently, depending on the type of coping strategies us…
ESTRATEGIAS Y ESTILOS DE AFRONTAMIENTO PARENTAL EN FAMILIAS CON NIÑOS CON TRASTORNO DE ESPECTRO AUTISTA (TEA) CON O SIN TRASTORNO POR DÉFICIT DE ATEN…
2015
La crianza de un hijo con Trastorno del Espectro Autista (TEA) ocasiona un fuerte impacto sobre la dinámica familiar. Cuando este trastorno se presenta con otro comórbido, como el Trastorno por Déficit de Atención con Hiperactividad (TDAH), las repercusiones sobre el bienestar psicológico de los padres pueden verse considerablemente aumentadas. Conocer qué estilos y estrategias de afrontamiento se emplean con mayor frecuencia podría contribuir a diseñar intervenciones con las familias, que pudieran repercutir positivamente en la manifestación de la sintomatología autista. El objetivo de este estudio consiste en profundizar en los estilos y estrategias de afrontamiento más frecuentes de esta…
Management of children with autism spectrum disorder in the dental setting
2013
Objectives: This article reviews the present literature on the issues encountered while coping with children with autistic spectrum disorder from the dental perspective. The autistic patient profile and external factors affecting the oral health status of this patient population are discussed upon the existing body of evidence. Material and Methods: The MEDLINE database was searched using the terms ‘Autistic Disorder’, ‘Behaviour Control/methods’, ‘Child’, ‘Dental care for disabled’, ‘Education’, ‘Oral Health’, and ‘Pediatric Dentistry’ to locate related articles published up to January 2013. Results: Most of the relevant studies indicate poor oral hygiene whereas they are inconclusive rega…
Media and corruption scandals in Spain: plaintiffs, magnifiers, accomplices?
2013
Partiendo de la idea según la cual el periodismo es, en regímenes de tradición liberal democrática, un freno a la arbitrariedad de los que gobiernan y de que los medios de comunicación, y en especial la prensa escrita, han acometido la tarea de vigilancia de los casos de corrupción acaecidos en la España democrática, se indaga sobre los mecanismos que dificultan el ejercicio de un periodismo de denuncia de la corrupción política y se proponen orientaciones para acercar la ética periodística a la ética cívica propia de la democracia. Starting from the idea that journalism is, in liberal democratic regimes tradition, a brake on the arbitrariness of those who govern and that the media, particu…
