Analysis of the Overdispersed Clock in the Short-Term Evolution of Hepatitis C Virus: Using the E1/E2 Gene Sequences to Infer Infection Dates in a Si…

2006

Abstract The assumption of a molecular clock for dating events from sequence information is often frustrated by the presence of heterogeneity among evolutionary rates due, among other factors, to positively selected sites. In this work, our goal is to explore methods to estimate infection dates from sequence analysis. One such method, based on site stripping for clock detection, was proposed to unravel the clocklike molecular evolution in sequences showing high variability of evolutionary rates and in the presence of positive selection. Other alternatives imply accommodating heterogeneity in evolutionary rates at various levels, without eliminating any information from the data. Here we pre…

The role of working memory on writing processes.

2021

Literature has extensively demonstrated the coordination role of working memory (WM) in complex tasks such as writing. However, previous studies mostly concentrated on the relation between passive WM (e.g., WM span) components and specific writing tasks (e.g., dictation). Here, we aimed to investigate the relationship between different writing skills and the performance on a WM updating task measuring the more active components of WM. From a pool of 160 Italian pupils (grades 3–5), we selected 46 children divided in two groups based on their WM updating performance. The first group consisted of 21 children with low WM updating performance (≤10th percentile), the second group consisted of 25…

The executive functions of shifting updating and inhibition and their association with arithmetical abilities.

2008

The study aimed to investigate, in 110 children attending the fourth class of an Italian primary school, the relationships between the executive functions of shifting, updating and inhibition and various aspect of arithmetic (written calculation, arithmetical facts and numeral knowledge). Shifting was assessed rating time and errors in color/number and number/letter Making trails task. Updating was assessed using Palladino et al.’s task (2001). Inhibition of endogenous information was assessed rating intrusion errors in Updating task, whereas effortful inhibition of exogenous interference and automatic inhibition of endogenous information were respectively assessed using Stroop and Negative…

MASCHILITÀ OMOSESSUALI TRA SESSO E AMICIZIA. COME LE ‘DATING APPS’ RISCRIVONO I COPIONI SESSUALI NEL XXI SECOLO

2021

This paper analysis sexual scripts theory in relation to gay men courtship, love relationships, and casual sex. The aim is to understand how gay masculinity is evolving in the 21st Century. Previous research has reinforced the concept that gay men follow heterosexual masculinity and scripts in their relationships with other men. Here, analysing data from the most used gay dating app ‘Grindr’, we try to understand the balance among the different needs gay men in Italy express in their daily lives: from friendship to love, from casual sex to long-term relationships. Indeed, applying the heterosexual cultural script to gay men is problematic because hegemonic masculinity is also reinforced in …

Effectiveness of a mobile app intervention to prevent dating violence in residential child care

2020

ABSTRACT This study focuses on the effectiveness of an app-based, monitored intervention using the Liad@s app in a residential youth-care setting. The aim of this intervention is to reduce maladaptive beliefs and attitudes linked to dating violence: distortions or myths about romantic love and hostile and benevolent dimensions of sexism. A quasi-experimental pre-post study with a control group was carried out. Participants were 71 adolescents from 9 group homes in Valencia (Spain). The outcomes measures were hostile and benevolent sexism (Ambivalent Sexism Inventory - ASI), ambivalence and prejudice towards men (Ambivalence toward Men Inventory - AMI), and myths about romantic love. The res…

New insights into the neolithisation process in southwest Europe according to spatial density analysis from calibrated radiocarbon dates

2017

The agricultural way of life spreads throughout Europe via two main routes: the Danube corridor and the Mediterranean basin. Current archaeological literature describes the arrival to the Western Mediterranean as a rapid process which involves both demic and cultural models, and in this regard, the dispersal movement has been investigated using mathematical models, where the key factors are time and space. In this work, we have created a compilation of all available radiocarbon dates for the whole of Iberia, in order to draw a chronological series of maps to illustrate temporal and spatial patterns in the neolithisation process. The maps were prepared by calculating the calibrated 14C date …

Towards a dendrochronologically refined date of the Laacher See eruption around 13,000 years ago

2020

Highlights • Previous age estimates of the Laacher See Eruptions (LSE) around 12,900 years are still diverging and imprecise. • The combination of dendrochronology, wood anatomy, and 14C measurements holds the potential to establish a precise LSE date. • An absolute calendric date of the LSE would improve the synchronization of European Late Glacial to Holocene archives. Abstract The precise date of the Laacher See eruption (LSE), central Europe’s largest Late Pleistocene volcanic event that occurred around 13,000 years ago, is still unknown. Here, we outline the potential of combined high-resolution dendrochronological, wood anatomical and radiocarbon (14C) measurements, to refine the age …

De la monogamie au « polygaming »…

2014

Les sites de rencontres ont favorisé l’essor d’un « papillonnage » numérique intensif. Maints inscrits de ces sites inventent à leur corps défendant de nouvelles manières d’aimer, déliées des exigences de la fidélité ou de l’inscription dans la durée. Les cadres normatifs évoluent, alors qu’Internet offre désormais à la rencontre amoureuse de nouveaux terrains de « drague » et des modalités technologiques et relationnelles augmentées. Ce dispositif permet l’émergence de rapports d’un nouveau genre, tout en industrialisant la rencontre amoureuse. Le polygaming est une solution de rechange sentimentalo-sexuelle bousculant la monogamie instituée en favorisant l’essor de relations ludiques, plu…
