Influence of ventral tegmental area (A10 region) on flight behaviour elicited by hypothalamic stimulation in the cat.

1993

The influence of the ventral tegmental area (VTA) (dopaminergic A10 group neurons) on flight behaviour, induced by hypothalamic stimulation, was studied in the cat. Co-stimulation of hypothalamus and VTA (ipsi- or contralateral) induced an increase of the flight latency. Slow-motion analysis of flight behaviour showed that this increase was due to the augmentation of the fixation latency (FL) whereas the upright latency (UL) was not modified. Sulpiride injection (50 mg/kg i.p.) provoked the disappearance of VTA effect without affecting the basal behavioural sequence. The results show that DA A10 group neurons increase the attentive component of the flight reaction, suggesting a possible inf…

Narrativa dei Caraibi nel nuovo millennio

2020

L’etichetta “Letterature franco-caraibica” utilizzata, per convenzione, dalla critica per indicare unitariamente la produzione letteraria in lingua francese della regione centrale del Continente americano è assai impropria. La regione dei Caraibi abbraccia, infatti, sia alcune delle isole dell’arcipelago delle Piccole Antille (Martinica, Guadalupa), sia l’isola di Haïti, che fa parte delle Grandi Antille, che la Guiana incastonata sulla costa orientale dell’America meridionale. Pur nella diversità dei movimenti ideologici e degli avvenimenti storici che si sono succeduti nella regione, le opere letterarie degli scrittori caraibici francofoni, nel loro insieme, hanno oscillato, e continuano …

The definition "Franco-Caribbean Literature" used by convention from the critique to indicate all the literary production in French of the central region of the American continent is very improper. The Caribbean region includes in fact the islands of Martinique Guadeloupe Haïti and the Guiana. Despite the diversity of ideological movements and historical events that took place in these countries the literary works of the Caribbean writers have fluctuated and continue to oscillate between two tendencies: that of rooting in tradition and that of escape from it. The writers show themselves open to comparison and dialogue with other literary and cultural traditions in order to create a narrative form that corresponds to the many inheritances of those composite populations. Here the cultural syncretism that has been created allows to recognize a common identity in the name of all that the West wanted to extinguish. The common denominator seems to be inverted in the contradictory result of courageous but dangerous encounters of curiosities that can lead to conflicts to exclusions.

Resistance to virus infection mediated by artificial microRNAs: estimating the likelilhood of escape mutants

2013

Las plantas sufren las infecciones causadas por muchos patógenos como hongos, bacterias, virus y nematodos. Las infecciones virales son persistentes y frecuentemente no se curan por el sistema inmune como en los animales. Existe una alta gama de virus de plantas, alrededor de 450 especies bien caracterizadas, que cusan una alta gama de enfermedades en plantas. Enfrentando esta situación, las planas no son meros sujetos pasivos, sino que han desarrollado mecanismos defensivos elaborados y efectivos para prevenir, o limitar, los daños causados a las infecciones virales. Entre estos mecanismos de defensa, las plantas tienen genes que confieren resistencia a virios patógenos, incluyendo los vir…

Bēgšana no realitātes Maikla Šabona darbā „Kavaliera un Kleja brīnumainie piedzīvojumi”

2017

Šajā darbā tiek pētīta terminu “bēgšana no realitātes” un “literatūra bēgšanai no realitātes” nozīme, un tiek parādīts, kā laika gaitā ir attīstījusies šo jēdzienu uztvere. Darba galvenā daļa ir veltīta tam, lai analizētu, vai Maikla Šabona darbs “Kavaliera un Kleja brīnumainie piedzīvojumi” var tikt kategorizēts kā literatūra bēgšanai no realitātes, izpētot dažādus bēgšanas no realitātes veidus, kas parādās šajā grāmatā, kā arī izpētot attiecības starp fantastikas literatūru un Holokausta literatūru. Darba galvenais secinājums ir tāds, ka bēgšana no realitātes ne vienmēr ir bezjēdzīga un “Kavaliera un Kleja brīnumainie piedzīvojumi” ir grāmata, kas parāda bēgšanas no realitātes transformēj…

Social servicescape effects on post-consumption behavior

2016

Purpose The purpose of this paper is to determine the role played by the social servicescape and positive emotions in the post-use in terms of response – satisfaction, perceived value and consumer loyalty – in hedonic services. Design/methodology/approach A quantitative study was conducted to gather data from 867 opera-goers through e-mail with a link to a questionnaire. Hypotheses were tested using structural equation modeling based on partial least squares. The effects of the social servicescape and emotions as moderators were examined using interaction techniques. Findings The paper provides empirical support on the multidimensional configuration of the social servicescape composed by b…

Parasite-induced change in host behaviour and susceptibility to predation in an eye fluke–fish interaction

2004

Abstract Trophically transmitted parasites may increase their transmission efficiency by altering the behaviour of infected hosts to increase their susceptibility to predation by target hosts (the next host in the life cycle). The parasite Diplostomum spathaceum (Trematoda) reduces the vision of its fish intermediate hosts: its metacercariae lodge themselves in the eyes of fish and induce cataract formation, which gives them the opportunity to affect fish behaviour. We examined whether D. spathaceum eye flukes change the preference of fish for the surface layers of the water column or their escape behaviour, which could make the fish more vulnerable to predation by bird hosts. We also studi…

An erratic dropstone of granodiorite with a water-escape structure from a Weichselian terrace along the River Gauja (NE Latvia)

2016

Abstract A river terrace of the River Gauja (Latvia), built of Weichselian glaciolacustrine deposits, contains a large number of erratic boulders from the Fennoscandian Shield. These erratic boulders include several types of granites and granodiorites. Some of the granodiorites are so strongly weathered that they fall apart into mm-sized grains of individual minerals when it is attempted to take them out of the host sediment. This strongly weathered nature makes them physically comparable to unconsolidated sand. A consequence is that they may be subjected to soft-sediment deformation. The erratic granodiorite boulder under study here is the first described to show such a soft-sediment defor…

La cultura ci salverà? Processi di touristification a base culturale nel centro storico di Palermo

2023

Negli ultimi tre decenni la cultura ha avuto un ruolo chiave nella costruzione delle politiche urbane, divenendo uno strumento decisivo nella definizione delle strategie di sviluppo economico e nell’accesso alla competizione globale che caratterizzano l’attuale regime di neoliberismo urbano (Miles e Paddison 2005). Anche nel sud Europa la cosiddetta rigenerazione a base culturale ha rappresentato e continua ancora oggi a rappresentare una vera e propria ortodossia urbana, che trova nel turismo tanto una ragione di esistenza quanto un campo di attuazione. In particolare, negli ultimi anni i centri storici di molte città sudeuropee sono stati oggetto di trasformazioni profonde in cui pratiche…

Within this framework Palermo and its historic center are no exception. The epicenter of these processes is represented here by the Kalsa district which since the early 2000s has been placed at the center of a precise strategy of culturally-based renewal called to drive the city's tourist renaissance (Vinci 2008). The culmination of this path came in 2018 when Palermo was named the Italian capital of culture and chosen as the venue for Manifesta one of the most prestigious traveling biennales of contemporary art. However the exponential increase in tourist arrivals in the last three years came to a halt with the outbreak of the pandemic which showed with unprecedented evidence the contradictions of the development strategies pursued in the historic center and the marks they leave on the territories. While this sudden interruption seems to offer an opportunity to radically rethink urban and cultural policies and find new curbs to the conditions of overtourism in which the historic centers of South European cities and beyond find themselves it could also prove to be an accelerator of the dynamics of commodification of these spaces representing the revival of tourism an easy escape route in times of crisis. The objective of this contribution is to critically explore the urban and social transformations that have crossed the Kalsa district of Palermo from the 2000s to the present using qualitative and quantitative techniques (analysis of statistical data in-depth interviews critical discourse analysis ...) with particular reference to the role that culture has played in these processes. While it is impossible to prefigure post-pandemic scenarios we will examine documents and discourses that trace possible development directions for South European cities and their historic centers.Settore ICAR/21 - UrbanisticaSettore M-GGR/01 - Geografia

Manipulative parasites may not alter intermediate host distribution but still enhance their transmission: field evidence for increased vulnerability …

2013

SUMMARYBehavioural alterations induced by parasites in their intermediate hosts can spatially structure host populations, possibly resulting in enhanced trophic transmission to definitive hosts. However, such alterations may also increase intermediate host vulnerability to non-host predators. Parasite-induced behavioural alterations may thus vary between parasite species and depend on each parasite definitive host species. We studied the influence of infection with 2 acanthocephalan parasites (Echinorhynchus truttae and Polymorphus minutus) on the distribution of the amphipod Gammarus pulex in the field. Predator presence or absence and predator species, whether suitable definitive host or …
