Il ruolo dell'informazione contestuale e delle componenti sillabico-accentuali nella decodifica del testo scritto: un confronto tra dislessici evolut…
2010
L'esperimento qui presentato si propone di valutare l'importanza che assume, per un dislessico evolutivo rispetto ad un normolettore, la presenza di indizi che suggeriscano il significato del testo scritto (informazioni contestuali), nonché l'influenza di determinate caratteristiche sillabico-accentuali nelle prestazioni di lettura. Lo studio è stato condotto attraverso la somministrazione di frasi in ognuna delle quali è stata inserita una parola target secondo criteri relativi alla posizione (dislocazione a sinistra e dislocazione a destra) al fine di valutare l'influenza esercitata dall'informazione contestuale durante la decifrazione del testo. Le parole selezionate sono state accuratam…
Diseased Social Predators
2017
Social predators benefit from cooperation in the form of increased hunting success, but may be at higher risk of disease infection due to living in groups. Here, we use mathematical modeling to investigate the impact of disease transmission on the population dynamics benefits provided by group hunting. We consider a predator-prey model with foraging facilitation that can induce strong Allee effects in the predators. We extend this model by an infectious disease spreading horizontally and vertically in the predator population. The model is a system of three nonlinear differential equations. We analyze the equilibrium points and their stability as well as one- and two-parameter bifurcations. …
HUMAN SMUGGLING AND IRREGULAR IMMIGRATION IN THE EU: FROM COMPLICITY TO EXPLOITATION?
2016
The paper provides a comparative analysis of the EU and the UN to the fight against smuggling. The two approaches are considerably different; and, since the one in the UN documents is more respectful of the smuggled migrants' rights, the paper suggests that a similar approach should also be embraced by the EU documents.
Traits that define the different alcohol intensive consume type during the practice of "botellon".
2012
Un fenómeno que en España favorece el actual patrón de consumo de alcohol juvenil es el conocido como botellón. A partir de una investigación financiada por el Plan Nacional sobre Drogas (2004-2007), se recogieron datos de 6009 jóvenes entre 14 y 25 años en tres ciudades españolas, considerando para este trabajo a quienes realizan episodios de consumo intensivo de alcohol (n = 2807). El objetivo ha sido identificar los distintos tipos de consumidores de riesgo intensivos mediante un análisis de conglomerados y establecer el perfil característico de cada uno. Se diferencian cuatro grupos en función de la edad, sexo, cantidad de alcohol y años de consumo. Los estudiantes de secundaria ingiere…
The role of peer groups in male and female adolescents' task values and physical activity.
2011
The purpose of this longitudinal study was to examine the role of peer groups and sex in adolescents' task values and physical activity. The participants were 330 Finnish Grade 6 students (173 girls, 157 boys), who responded to questionnaires that assessed physical education task values during the spring semester (Time 1). Students' physical activity was assessed one year later (Time 2). The results indicated that adolescent peer groups were moderately homogeneous in terms of task values toward physical education and physical activity. Girls' peer groups were more homogeneous than those of boys in regards to utility and attainment values. Furthermore, the results for both girls and boys sh…
Parenting Mechanisms in Links Between Parents’ and Adolescents’ Alcohol Use Behaviors
2007
Background: Adolescence has been identified as a critical period with regard to the initiation and early escalation of alcohol use. Moreover, research on familial risk and protective processes provides independent support for multiple domains of parental influence on adolescent drinking; including parents' own drinking behaviors, as well as the practices they employ to socialize their children. Despite this prevalence of findings, whether and how these distinct associations are related to one another is still not entirely clear. Methods: The present study used data from 4,731 adolescents and their parents to test the nature of associations between (a) parents' frequencies of alcohol use and…
An empirical test of neighbourhood effect and safe-site effect in abandoned Mediterranean vineyards
2011
The importance of both neighbourhood effect and safe-site effect for the colonization of Mediterranean old fields by woody plants was investigated. Using a transect approach, we recorded colonization of 21 species of woody plants on abandoned, terraced vineyards on Pantelleria Island (Sicily) in dependence from neighbouring terraces in older succession stages (Maquis) and available safe sites for seedling establishment (former crop plant, terrace wall). With a paired design of four treatments, including presence/absence of adjacent older successional stages, and North-/South-facing slopes, a neighbourhood effect could be shown for both expositions if the transect started from an adjacent fi…
L’incriminazione dello smuggling of migrants in Europa: una ricognizione comparatistica
2019
Il lavoro opera una ricognizione comparatistica di varie discipline del migrant smuggling: internazionale (Protocollo ONU), sovranazionale (UE Facilitation package) e nazionali (Italia, Portogallo, Spagna, Germania), a partire dai dati raccolti nel corso della ricerca "The New Era of Smuggling in the Mediterranean Sea" (2017-19), finanziata da PMI
Smuggled migrants as victims? Reflecting on the UN Protocol against migrant smuggling and on its implementation
2021
After outlining the UN Protocol’s general approach to migrant smuggling, the paper raises the question of whether and to what extent smuggled migrants can be said to be victims of this crime. The author argues that an affirmative answer is possible in at least three different senses: smuggled migrants can be victimized by states fighting against migrant smuggling and irregular immigration (secondary victimization); but, of course, they can also be victimized by smugglers (primary victimization), in two ways: first, if smuggling is so performed as to put their lives, physical integrity or dignity at risk; secondly, smugglers also victimize migrants by profiting of their vulnerable condition,…
Disruption of Slc4a10 augments neuronal excitability and modulates synaptic short-term plasticity
2015
Slc4a10 is a Na(+)-coupled Cl(-)-HCO3 (-) exchanger, which is expressed in principal and inhibitory neurons as well as in choroid plexus epithelial cells of the brain. Slc4a10 knockout (KO) mice have collapsed brain ventricles and display an increased seizure threshold, while heterozygous deletions in man have been associated with idiopathic epilepsy and other neurological symptoms. To further characterize the role of Slc4a10 for network excitability, we compared input-output relations as well as short and long term changes of evoked field potentials in Slc4a10 KO and wildtype (WT) mice. While responses of CA1 pyramidal neurons to stimulation of Schaffer collaterals were increased in Slc4a1…
