Imprese e reti per lo sviluppo imprenditoriale del territorio. Teoria e casi di destination management
2012
Il presente volume raccoglie i contributi al Workshop “Imprese e reti per lo sviluppo imprenditoriale del territorio: teoria e casi di Destination Management” tenutosi a Napoli il primo giugno del 2012. Alla raccolta i curatori hanno voluto premettere due saggi di contenuto teorico: l’uno concretizza un inquadramento istituzionale al tema, l’altro richiama uno dei più dibattuti driver di ricerca, quello del brand della destinazione. Ognuno dei lavori presentati al Workshop si offre quale elemento contributivo al più ampio dibattito che vede il turismo come momento trainante dello sviluppo socio-economico di un territorio, uno sviluppo che ormai non può non qualificarsi in termini di sosteni…
Speeches About Men and Women in Technical Education: Between Reproduction and Transformation. A Study Located in Two Argentinian Provinces
2020
La formación técnica en Argentina ha sido un ámbito históricamente masculinizado. Ante el incremento de la matrícula femenina y la visibilización y demandas sociales respecto de las desigualdades de género, nos preguntamos, de qué manera las instituciones de ETP favorecen el reconocimiento y la participación con miras a la justicia social. Este trabajo analiza discursos sobre las desigualdades entre varones y mujeres (en interseccionalidad con otras) que circulan en 12 instituciones de educación técnico profesional en dos provincias argentinas (Neuquén y Mendoza), y sobre los dispositivos de acompañamiento a la escolaridad y articulación con el trabajo que allí se construyen. Desplegamos un…
Cuevas rituales ibéricas en el territorio de Kelin (ss. V-III a.C.).
2018
La Meseta de Requena-Utiel, en el interior de la provincia de Valencia, constituyó en época ibérica el territorio de la ciudad de Kelin. Entre otros aspectos, dicho territorio destacó por presentar una elevada concentración de cuevas con materiales ibéricos, de las cuales claramente cinco son resultado de prácticas rituales en su interior. Estas cuevas rituales fueron espacios estrechamente ligados al proceso de territorialización acaecido en la zona entre los siglos V y III a.C. En el presente artículo planteamos una revisión de sus características, ajuares y cronologías, integrándolas en todo momento en el paisaje y entorno inmediato. The Requena-Utiel plateau, in the interior of the Prov…
Adaptive strategies of territory formation
2003
How do territorial animals gain ownership of an area? Early modelling has considered the evolution of fighting when the winner can claim the right to the resource. Recently, alternative hypotheses have been offered where repeated interactions lead to division of space through 'nagging' instead of one decisive fight. However, these models assume that animals avoid areas in which they have taken part in aggressive interactions, but do not consider whether avoidance itself is adaptive. We aim to bridge this gap between mechanistic and adaptive explanations, by presenting a game-theory model where individuals choose whether to return to an area after a fight with a specific outcome (win, loss, …
Demographic responses of a site-faithful and territorial predator to its fluctuating prey: long-tailed skuas and arctic lemmings.
2014
Summary1. Environmental variability, through interannual variation in food availability or climaticvariables, is usually detrimental to population growth. It can even select for constancy in keylife-history traits, though some exceptions are known. Changes in the level of environmentalvariability are therefore important to predict population growth or life-history evolution.Recently, several cyclic vole and lemming populations have shown large dynamical changesthat might affect the demography or life-histories of rodent predators.2. Skuas constitute an important case study among rodent predators, because of theirstrongly saturating breeding productivity (they lay only two eggs) and high deg…
Managing the Historical Agricultural Landscape in the Sicilian Anthropocene Context. The Landscape of the Valley of the Temples as a Time Capsule
2021
The debate over whether we are entering the Anthropocene Epoch focuses on the unequal consumption of the Earth system’s resources at the expense of nature’s regenerative abilities. To find a new point of balance with nature, it is useful to look back in time to understand how the so-called “Great Acceleration”—the surge in the consumption of the planet’s resources—hastened the arrival of the Anthropocene. Some particular places—for various reasons—survived the Great Acceleration and, as time capsules, have preserved more or less intact some landscape features that have disappeared elsewhere. How can we enhance these living archives that have come down to us? Through the analysis of the case…
Evolutionary conservation advice for despotic populations: habitat heterogeneity favours conflict and reduces productivity in Seychelles magpie robins
2010
Individual preferences for good habitat are often thought to have a beneficial stabilizing effect for populations. However, if individuals preferentially compete for better-quality territories, these may become hotspots of conflict. We show that, in an endangered species, this process decreases the productivity of favoured territories to the extent that differences in productivity between territories disappear. Unlike predictions from current demographic theory on site-dependent population regulation (ideal despotic distribution), we show that population productivity is reduced if resources are distributed unevenly in space. Competition for high-quality habitat can thus have detrimental con…
Territoriality versus flocking in the Zenaida dove (Zenaida aurita): resource polymorphism revisited using morphological and genetic analyses.
2011
11 pages; International audience; The term “resource polymorphism” refers to the existence of alternative phenotypes in relation to resource use, as a result of disruptive selection. Evidence for resource polymorphism is widespread in fish but remains scarce in birds. Although Zenaida Doves (Zenaida aurita) usually defend year-round territories, doves on Barbados can also be observed foraging at seed-storage sites in large flocks with little, if any, inter-individual aggression. On the basis of morphological variation, it has been suggested (Sol et al. 2005) that this represents a case of resource polymorphism, primarily driven by competition for territories. Using new data, we revisited th…
Individual dispersal status influences space use of conspecific residents in the common lizard, Lacerta vivipara
2006
The effects of immigration on the behaviour of residents may have important implications for the local population characteristics. A manipulative laboratory experiment with yearlings of the common lizard (Lacerta vivipara) was performed to test whether the introduction of dispersing or philopatric individuals influences the short-term spacing behaviour of resident individuals. Staged encounters were carried out to induce interactions within dyads. The home cage of each responding individual was connected by a corridor to an unfamiliar “arrival cage” to measure the latency to leave their own home cage after each encounter. Our results showed that the time that pairs spent in close proximity …
Density dependence of infanticide and recognition of pup sex in male bank voles
2010
[Infanticide — the killing of conspecific young — is a common phenomenon in many invertebrate and vertebrate species, particularly common in rodents. It can increase juvenile mortality and, thus, affect population growth. Male infanticide is explained by adaptive hypotheses based on sexual selection. Removing future competitors for mating opportunities would require recognition of pup sex and directing infanticide against male pups. We studied whether the sex of a pup and population density affect male bank voles' ( Myodes glareolus ) aggressive behaviour towards conspecific pups. Population density increased aggressiveness. Against our predictions, male bank voles from high density populat…
