Similarities between Playing World of Warcraft and CLIL

2012

This article argues that playing World of Warcraft (WoW) and Content and Language Integrated Learning (CLIL) have a number of similar features. We base our argument on findings from three studies. The first (Sylvén 2004/2010) is about CLIL and non-CLIL students at upper secondary level and aims to investigate what effect, if any, CLIL has on the incidental acquisition of vocabulary. The second (Sundqvist 2009) is about extramural English and aims to examine its potential impact on learners’ oral proficiency and vocabulary. Extramural English is broadly defined as any type of contact that learners have with English outside the classroom. The third is a joint study focusing on young learners …

La coppia cogenitoriale

2019

Il rapporto fra cogenitori come coppia ha un impatto notevole, certamente, sulla crescita dei figli. Occorre, innanzitutto, ricordare che ogni figlio costituisce un essere unico che, pur condividendo con i fratelli una parte del patrimonio genetico, ha proprie caratteristiche distintive: dall’ordine di genitura al genere, dal fatto di nascere in un determinato periodo della vita della famiglia, alle particolari aspettative che tutti i membri della famiglia creano intorno alla sua esistenza (Aparo, 2018). Nel processo educativo, l’ascolto e la comprensione della propria reciproca storia e la condivisione di problemi e desideri con l’altro genitore può portare non solo ad una migliore comunic…

The effect of social information from live demonstrators compared to video playback on blue tit foraging decisions.

2019

Video playback provides a promising method to study social interactions, and the number of video playback experiments has been growing in recent years. Using videos has advantages over live individuals as it increases the repeatability of demonstrations, and enables researchers to manipulate the features of the presented stimulus. How observers respond to video playback might, however, differ among species, and the efficacy of video playback should be validated by investigating if individuals’ responses to videos are comparable to their responses to live demonstrators. Here, we use a novel foraging task to compare blue tits’ (Cyanistes caeruleus) responses to social information from a live …

Deteriorated stabilization of walking in individuals with spastic cerebral palsy revealed by a simulated tripping perturbation

2014

Abstract. The aim of this study was to make use of a pr eviously introduced method of a simulated tripping perturbation to examine stability of walking in individuals with and with out cerebral palsy. This tripping perturbation is a forward-dynamics analys is, and it works so that in a subjec t-specific muscle-driven simulation of walking, created from experimental gait data, a force is applied to the swin g-foot, and resulting changes in the kinematics are observed. Here, changes in the fore-aft position of the trunk were analyzed. Subjects were 10 children with spastic diplegic cerebral palsy and eight un impaired children walking at their self-sel ected speed. Several tripping perturbati…

The gait is less stable in children with cerebral palsy in normal and dual-task gait compared to typically developed peers

2021

There is limited evidence about gait stability and its alteration by concurrent motor and cognitive tasks in children with cerebral palsy (CP). We examined gait stability and how it is altered by constrained cognitive or motor task in CP and their typically developed (TD) controls. Gait kinematics were recorded using inertial-measurement units (IMU) from 18 patients with hemiplegia (13.5 +/- 2.4 years), 12 with diplegia (13.0 +/- 2.1 years), and 31 TD controls (13.5 +/- 2.2 years) during unconstrained gait, and motor (carrying a tray) and cognitive (word naming) task constrained gait at preferred speed (similar to 400 steps/task). Step duration, its standard deviation and refined-compound-m…

Identification of inorganic pigments from paintings and polychromed sculptures immobilized into polymer film electrodes by stripping differential pul…

2000

Abstract Inorganic pigments in paintings and polychromed sculptures are studied by cyclic voltammetry and differential pulse stripping voltammetry using micro-sample coatings in Paraloid B72-film modified electrodes. Characteristic cathodic and anodic differential pulse profiles were obtained in the +0.4 to −1.0 V vs. SCE potential range for different cadmium, copper, lead, mercury and zinc pigments used in traditional colour palettes. Under optimized conditions, excellent reproducibility was obtained. Microsamples extracted from polychromed sculptures, wall paintings, canvas paintings, panel paintings and altarpieces from Spain, Ethiopia and Italy from the 12th to the 20th centuries have b…

Formation and Stability of Cadmium(II)/Phytate Complexes by Different Electrochemical Techniques. Critical Analysis of Results

2010

In the present work the stability constants of various cadmium(II)/phytate (Phy) species were determined at T = 298.15 K in NaNO3(aq) at I = 0.1 mol·L−1 by DP-ASV (Differential Pulse Anodic Stripping Voltammetry) and by potentiometric titrations using an ISE-Cd2+. Cyclic voltammograms were also recorded to check the electrochemical behavior of cadmium in the presence of phytate. The results were analyzed together with previous data determined by ISE-H+ measurements. Data obtained were used to provide an exhaustive speciation scheme for the phytate/cadmium(II) system at different conditions, as well as a comprehensive representation of the binding ability of phytate toward cadmium(II). Diffe…

Glutamatergic projection from the nucleus incertus to the septohippocampal system

2012

Abstract Recent findings support a relevant role of the nucleus incertus in the control of the hippocampal activity through the modulation of theta rhythm. Previous studies from our group have shown that this nucleus is a critical relay between reticularis pontis oralis and the medial septum/diagonal band, regarded as the main activator and the pacemaker of the hippocampal oscillations, respectively. Besides, the nucleus incertus is highly linked to activated states related to the arousal response. The neurotransmission of the nucleus incertus, however, remains uncertain. Only GABA and the neuromodulator relaxin 3 are usually considered to be involved in its contribution to the septohippoca…
