La prospettiva dei beneficiari. Accesso e (auto)rappresentazioni
No full textThe chapter focuses on two main issues: becoming a beneficiary and the identity dimension related to the status of a recipient of a minimum income scheme, paying particular attention to the dimension of (self-)representation, strategies and pitfalls. The first part of the chapter analyses the factors and conditions that lead to the decision to turn to public assistance and apply for income support. The second part of the chapter deals with the construction of the beneficiary identity through three thematic foci. The chapter consists of an introductory section, which serves to frame the academic debate on the issues addressed, followed by a central body of analysis organised along conceptual lines, and concluding with a discussion section, which puts the empirical findings in dialogue with the debate

Adaptation to high-frequency vibrotactile stimulations fails to affect the clock in young children
No full textBeing able to estimate time precisely is fundamental to interact with the environment, and it is startling how our ability to track temporal intervals is prone to distortion. Unsurprisingly, researchers have studied temporal distortions extensively. Within the internal clock model framework, they have been often accounted for a change in the pacemaker's speed. However, only a few studies have tested whether these changes are eligible in children, investigating temporal distortions mainly via classical temporal bisection (in which participants should compare temporal stimuli with previously memorized durations). Since both temporal and non-specific, higher level factors mediate performance in such tasks, we decided to test time distortions in children by using a more low-level, perceptual design. Using a discrimination task and adaptation to high and low frequency vibrotactile stimulations, we compared haptic duration aftereffects in both young children (from 6 to 10 years of age) and adults. We found that sensory adaptation did not affect perceived duration in children up to 10 years of age, leading to an overall more rigid temporal representation among children who were younger. While adaptation to high frequency vibrotactile stimulations distorted perceived duration in both adults and 10 year-old children, younger participants did not experience change in perceived duration following adaptation. Conversely, adaptation to low frequency vibrotactile stimulations did not change the tested groups' perceived duration. Given the lack of temporal distortions to high frequency stimulations after adaptation in younger children, our results advocate for a different clock functioning. This suggests the internal clock functioning changes during development
One-class support vector machines identify the language and default mode regions as common patterns of structural alterations in young children with autism spectrum disorders
No full textThe identification of reliable brain endophenotypes of autism spectrum disorders (ASD) has been hampered to date by the heterogeneity in the neuroanatomical abnormalities detected in this condition. To handle the complexity of neuroimaging data and to convert brain images in informative biomarkers of pathology, multivariate analysis techniques based on Support Vector Machines (SVM) have been widely used in several disease conditions. They are usually trained to distinguish patients from healthy control subjects by making a binary classification. Here, we propose the use of the One-Class Classification (OCC) or Data Description method that, in contrast to two-class classification, is based on a description of one class of objects only. This approach, by defining a multivariate normative rule on one class of subjects, allows recognizing examples from a different category as outliers. We applied the OCC to 314 regional features extracted from brain structural Magnetic Resonance Imaging (MRI) scans of young children with ASD (21 males and 20 females) and control subjects (20 males and 20 females), matched on age [range: 22-72 months of age; mean = 49 months] and non-verbal intelligence quotient (NVIQ) [range: 31-123; mean = 73]. We demonstrated that a common pattern of features characterize the ASD population. The OCC SVM trained on the group of ASD subjects showed the following performances in the ASD vs. controls separation: the area under the receiver operating characteristic curve (AUC) was 0.74 for the male and 0.68 for the female population, respectively. Notably, the ASD vs. controls discrimination results were maximized when evaluated on the subsamples of subjects with NVIQ = 70, leading to AUC = 0.81 for the male and AUC = 0.72 for the female populations, respectively. Language regions and regions from the default mode network-posterior cingulate cortex, pars opercularis and pars triangularis of the inferior frontal gyrus, and transverse temporal gyrus-contributed most to distinguishing individuals with ASD from controls, arguing for the crucial role of these areas in the ASD pathophysiology. The observed brain patterns associate preschoolers with ASD independently of their age, gender and NVIQ and therefore they are expected to constitute part of the ASD brain endophenotype
Tuning Gaps and Schottky Contacts of Graphene/Phosphorene Heterostructures by Vertical Electric Field and Strain
No full textWe present a comprehensive study of the structural and electronic properties of a graphene/
phosphorene (G/P) heterostructure in the framework of density functional theory, including van der
Waals interaction in the exchange–correlation functional. While the G(4 1)/P(3 1) superlattice
usually used in the literature is subject to a strain as high as about 7%, the in-plane strain could
be drastically reduced to under 1% in the G(4 13)/P(3 12) heterostructure investigated here.
Adapting the lattice constants of the rectangular lattices, the equilibrium configuration in the xy
plane of phosphorene relative to the graphene layer is optimized. This results in an equilibrium
interlayer distance of 3.5 Å and a binding energy per carbon atom of 37 meV, confirming the presence
of weak van der Waals interaction between the graphene and the phosphorene layers. The electronic
properties of the heterostructure are evaluated under different values of interlayer distance, strain
and applied vertical electric field. We demonstrate that G/P heterostructures form an n-type Schottky
contact, which can be transformed into p-type under external perturbations. These findings, together
with the possibility to control the gaps and barrier heights, suggest that G/P heterostructures are
promising for novel applications in electronics and may open a new avenue for the realization of
innovative optoelectronic devices

An audio-visual motor training improves audio spatial localization skills in individuals with scotomas due to retinal degenerative diseases
No full textSeveral studies have shown that impairments in a sensory modality can induce perceptual deficits in tasks involving the remaining senses. For example, people with retinal degenerative diseases like Macular Degeneration (MD) and with central scotoma show biased auditory localization abilities towards the visual field's scotoma area. This result indicates an auditory spatial reorganization of cross-modal processing in people with scotoma when the visual information is impaired. Recent works showed that multisensory training could be beneficial to improve spatial perception. In line with this idea, here we hypothesize that audio-visual and motor training could improve people's spatial skills with retinal degenerative diseases. In the present study, we tested this hypothesis by testing two groups of scotoma patients in an auditory and visual localization task before and after a training or rest performance. The training group was tested before and after multisensory training, while the control group performed the two tasks twice after 10 min of break. The training was done with a portable device positioned on the finger, providing spatially and temporally congruent audio and visual feedback during arm movement. Our findings show improved audio and visual localization for the training group and not for the control group. These results suggest that integrating multiple spatial sensory cues can improve the spatial perception of scotoma patients. This finding ignites further research and applications for people with central scotoma for whom rehabilitation is classically focused on training visual modality only
