Association between sleep disorders, hyperacusis and tinnitus: Evaluation with tinnitus questionnaires
No full textPatients with tinnitus are heterogeneous and several factors influence the impact of this symptom on the quality of life. The aim of the study is to evaluate the relationship between age, gender, sleep disorders, hyperacusis and tinnitus annoyance and to demonstrate the utility of tinnitus questionnaires as screening tools for sleep disorders and hyperacusis in patients with tinnitus. 37 consecutive patients (18 males and 19 females) with subjective tinnitus lasting over 3 months were evaluated with a complete interview, otological examination, pure tone audiometry, Italian version of tinnitus sample case history (TSCH) and tinnitus handicap inventory (THI). Statistical analysis was performed with the Wilcoxon′s rank sum test, the Spearman′s rho non-parametric correlation and the logistic regression analysis. THI grades were slight (16%), mild (32%), moderate (30%), severe (19%) and catastrophic (3%). Based on the answers to TSCH 20 patients reported sleep disorders (54%) and 20 patients reported hyperacusis (54%). 11 patients (30%) reported sleep disorders and hyperacusis. No significant correlation was found between the severity of tinnitus and patients′ age and gender. Significant correlation was found between sleep disorders (P = 0.0009) and tinnitus annoyance and between hyperacusis (P = 0.03) and tinnitus annoyance. TSCH and THI may be considered as screening tools in the clinical practice to evidence sleep disorders and hyperacusis in patients with tinnitus
ERP Modulation during Observation of Abstract Paintings by Franz Kline
No full textThe aim of this study was to test the involvement of sensorimotor cortical circuits during the beholding of the static consequences of hand gestures devoid of any meaning.In order to verify this hypothesis we performed an EEG experiment presenting to participants images of abstract works of art with marked traces of brushstrokes. The EEG data were analyzed by using Event Related Potentials (ERPs). We aimed to demonstrate a direct involvement of sensorimotor cortical circuits during the beholding of these selected works of abstract art. The stimuli consisted of three different abstract black and white paintings by Franz Kline. Results verified our experimental hypothesis showing the activation of premotor and motor cortical areas during stimuli observation. In addition, abstract works of art observation elicited the activation of reward-related orbitofrontal areas, and cognitive categorization-related prefrontal areas. The cortical sensorimotor activation is a fundamental neurophysiological demonstration of the direct involvement of the cortical motor system in perception of static meaningless images belonging to abstract art. These results support the role of embodied simulation of artist's gestures in the perception of works of art. © 2013 Sbriscia-Fioretti et al
Individual Contacts, Collective Patterns. Prato 1975-97, a story of interactions.
No full textThis article presents an agent-based model (ABM) of an Italian textile district where thousands of small firms specialize in particular phases of fabrics production. It is an empirical model because it reconstructs the communications between firms when they arrange production chains. In their turn, production chains reflect into the pattern of road traffic in the geographical areas where the district extends. It is a methodological model because it aims to show that ABMs can be used to reconstruct a web of movements in geographical space. ABMs are proposed as a tool for Hägerstrand’s “time-geography”.Industrial districts, Industrial clusters, Agent-based models, Prato

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Multianalytical investigation of pigments in the Madonna della Croce wall painting (Triggiano, Italy)
No full textThe Madonna della Croce portrait is painted on a lunette, previously detached from a wall of unknown origin and now preserved on the right of the main altar in the Madonna della Croce church, in Triggiano (Bari, Italy). The wall painting, which depicts the Virgin and Child with St. Sebastiano and St. Rocco with their symbols of martyrium, was realised by a local artist who worked between 1550 and 1570 in the town.
The numerous legends about the wall painting, mixed with historical events, talk about miraculous healing stories which has strengthened the strong relationship of the Triggiano inhabitants with this religious symbol, such as they built a dedicated church and chose this Virgin as patron Saint of the town.
The presented research mainly focusses on the investigation of pictorial layers of this painting by a non-invasive multianalytical approach. Firstly, shape, size and optical features of pigments have been observed using a portable digital microscope equipped by a polarizing filter. By means of a portable spectrophotocolorimeter, colour of painting areas has been measured and expressed in the CIEL*a*b* system and for each of them reflectance spectra of visible light (400-700 nm) have been recorded. The identification of pigment composition has been carried out by FORS (fiber optic reflectance spectroscopy) and XRF (X-ray fluorescence spectroscopy). Produced spectra have been compared with databases available in literature.
Results have provided information about features and compositions of pigments, highlighting the use of red ochre, yellow ochre and carbon black for red and yellow paintings and for black profiles; in addition, mixing of red ochre and green earth and mixing of carbon black, lime and yellow ochre have been revealed respectively in correspondence to green background and blue Virgin mantle, as attested in other Apulian wall paintings (Fioretti et al. 2020; Fioretti et al. 2020)
Diversity and interculturalism, a critique and a defence. Going through multiethnic neighbourhoods in Rome
No full textExtract: Marco Cremaschi Carlotta Fioretti The starting hypothesis of this chapter is that the two different concepts of the diverse city and the intercultural city can be applied interchangeably to describe and govern multi-ethnic urban settings, the difference being more a matter of scale than of nature. Diversity and interculturalism share, in fact, the same duplicity: a normative content combined with an analytic orientation. The former, however, addresses mainly the ordinary configuration of places while the latter allows the discussion of rights and political principles. Are the diverse city and the intercultural city the same, then? The answer is affirmative, but conditional upon clearing both concepts of ideological deposits. Interculturalism, in particular, describes the attitude of governments towards integration intended as a process of exchange and interaction between the host and the immigrant population. At the same time, it suggests a normative model for balancing and accepting these exchanges. Interculturalism has..
