No full textLow-skill jobs and routine tasks specialization: new insights from Italian provinces
No full textThough the past decades Italy showed a lag in innovation, the 2000’s technology
may have started spreading some effect on the occupational composition of employment.
Past researches did not find evidence of skill-biased change. Since no paper so far ever addressed the topic of "routinazation" (and its link with labor market polarization) in Italy, this presentation analyses the period 2004-2016 assessing the routinisation hypothesis for the Italian labor market.though the past decades italy showed a lag in innovation, the 2000’s technology

The impact of cross-modal correspondences on working memory performance.
No full textCross-modal correspondences influence perceptual performance in adults, infants, and even nonhuman
primates across a variety of different sensory modalities and dimensions, including tasks involving
speeded detection, discrimination, and categorization. However, to date, it is still unclear whether and
how correspondences could modulate post-perceptual processes, such as working memory (WM). We
investigated this issue using a bimodal (audiovisual) two-back task. In Experiment 1, 3 kinds of
correspondences were used: audio/visual numerosity, pitch/shape, and pitch/elevation, each presented
congruently (e.g., for numerosity: 3 auditory tones along with 3 visual shapes) or incongruently (3 tones/2
shapes). Participants attended to the visual or auditory modalities, or both, simultaneously. The results
revealed faster target-detection latencies following congruent as compared to incongruent stimulation,
especially for numerosity congruence. In Experiment 2, we focused on numerosity, varying the corre-
spondence of the unattended modality, thus having correspondences at both sample (e.g., 3 tones/3
shapes) and target (e.g., 3 tones/3 shapes), only at sample (sample: 3 tones/3 shapes; target: 3 tones/2
shapes), only at target (sample: 3 tones/2 shapes; target: 3 tones/3 shapes), or never. To investigate the
format of the encoded information we also included “symbolic” quantities (i.e., visually/auditorily
presented digits). The results confirmed the congruence effects, specifically when the correspondence
operates at the target display, thus affecting response selection. The experiment also revealed modal
effects, showing how task-irrelevant digits affect performance only in the auditory modality, while
task-irrelevant quantities affect it only when presented visually. Overall, these findings highlight the
impact of cross-modal correspondences on WM processing, adding new light on the link between
perceptual and post-perceptual stages of human information processing
The impact of crossmodal correspondences on working memory performance
No full textEvidence in favor of Crossmodal Correspondences (CCs) have been collected both in infants and adults for different sensory modalities and dimensions in the perceptual domain, using speeded categorization or comparison tasks. However, it is still largely unexplored whether CCs can also modulate post-perceptual processes, such as Working Memory (WM). We investigated this issue in 2 Experiments, using a bimodal (audio-visual) 2-back task. In Experiment 1 we considered three kinds of CCs typically used in the perceptual domain: pitch/shape, pitch/elevation, and audio/visual numerosity, each presented congruently (e.g., for numerosity: three tones along with three shapes) or incongruently (e.g., three tones along with two shapes). Participants were divided in three groups according to the attended modality: vision, audition, or both. The results showed an overall impact of the different CCs on the n-back task performance, highlighting faster target-detection latencies following congruent vs. incongruent CCs. Experiment 2 focused on numerosity congruence/incongruence and confirmed these results, but only when the audiovisual correspondence remained stable and congruent between the sample and target display (i.e., when the two displays were audiovisually congruent and identical). This indicates that the enhancement of WM performance reflects the on-line maintenance of an integrated audiovisual representation involving the auditory and visual components of the CC, and not a mere arousal effect driven by the current congruent CC. Moreover, the two Experiments present evidence of an asymmetrical congruence effect across different sensory modalities (e.g. congruence effect on WM is maximized when attention is focused on a specific modality). Overall, these findings extend the existing knowledge about the influence of CCs on post-perceptual processing. Importantly, the impact of CCs in enhancing memory representation can contribute in shedding new light on the link between perceptual and post-perceptual, learning-mediated, stages of processing
Peer interactions, local markets, and wages: Evidence from Italy
No full textThis paper investigates the relationship between the spatial distribution of occupations with a high content of peer interactions and wages among Italian provinces. At this aim, we use a unique employer-employee dataset obtained by merging administrative data on wages and labor market histories of individuals, with survey data on job tasks and contents. The spatial distribution of jobs intensive in peer-interactions is further measured according to the occupational structure of Italian provinces. The econometric analysis shows that the concentration of peer interactions leads to higher wages at the province level. These results are robust to firms and workers’ heterogeneity and endogeneity issues.this paper investigates the relationship between the spatial distribution of occupations with a high content of peer interactions and wages among italian provinces. at this aim, we use a unique employer-employee dataset obtained by merging administrative data on wages and labor market histories of individuals, with survey data on job tasks and contents. the spatial distribution of jobs intensive in peer-interactions is further measured according to the occupational structure of italian provinces. the econometric analysis shows that the concentration of peer interactions leads to higher wages at the province level. these results are robust to firms and workers’ heterogeneity and endogeneity issues. peer interactions, local markets, and wages: evidence from italy irene brunetti valerio intraligi andrea ricci claudia vittor
Enrico IV ovvero il potere salvifico dell’immaginazione
No full textAmong the writings published by Umberto Artioli a year before his sudden death in July 2004, there is a study on Luigi Pirandello’s Enrico IV. Abandoning the usual realistic interpretation of the text, the scholar highlights the allegorical path underneath its conception and a number of references related to the evangelical Last Supper. The core of Pirandello’s hero teachings identifies in the theatrical imagination the way to salvation. Although the initiation of his disciples fails, the Author outlines the characteristics of a new type of artist and his ideal relationship with the public; a figure that will inspire Bontempelli’s ideas on an extremely versatile and eclectic interpreter to be driven on stage like a puppet
Wake-Up Right-Sided Hemiparesis and Dysarthria in a Heavy Snorer
No full textCase Presentation A 57-year-old man was referred to the ED for wake-up right-sided hemiparesis, hypoesthesia, dysarthria, and a National Institutes of Health Stroke Scale score of 7. Urgent CT brain scanning showed an ischemic lesion of the left temporal and insular lobes. The patient was admitted to the stroke unit, and acetylsalicylic acid 300 mg and low-molecular-weight heparin 6,000 IU were administered
