Sleep habits in children affected by autism spectrum disorders: A preliminary case-control study
2017
Introduction: The core of autism spectrum disorders (ASD) consists of alterations of neurological functions that affect the typical developmental trajectory leading to deficits in social interaction and non-verbal behaviors. In general, ASD is diagnosed at age three and many other frequent neurological signs may be present, such as sleep disorders. The aim of study is evaluating sleep habits in a sample of ASD children. Material and methods: The study population consists of 65 ASD children (43 males and 22 females), aged between 2 and 11 years (mean 5.73 ± 2.39 years). The control group consists of 114 children with typical development (68 males and 46 females), aged between 3 and 10 years …
Facing the Pandemic in Italy: Personality Profiles and Their Associations With Adaptive and Maladaptive Outcomes
2022
The negative impact of the COVID-19 pandemic on individuals’ psychosocial functioning was widely attested during the last year. However, the extent to which individual differences are associated with adaptive and maladaptive outcomes during quarantine in Italy remains largely unexplored. Using a person-oriented approach, the present study explored the association of personality profiles, based on three broad individual dispositions (i.e., positivity, irritability, and hostile rumination) and two self-efficacy beliefs in the emotional area (i.e., expressing positive emotions and regulating anger emotion), with adaptive and maladaptive outcomes during the first Italian lockdown (March–June 20…
Relazioni interpersonali, immagine corporea ed autostima in adolescenza. Uno studio condotto con studenti degli istituti superiori
2017
Previous research has evidenced the link between body image dissatisfaction, social anxiety, low self-esteem, negative affect and eating disorders in adolescence. The present study aimed to explore the gender differences on body image perception, self-esteem, and relational styles in a group of adolescents and to investigate whether body image and self-esteem predict the development of interpersonal problems in a different way for males and females. Method: Data were obtained from a group (n = 1311) of adolescents (805 males and 506 females), recruited in a high school in Palermo. Participants filled in the BIAI, the IIP-32 and the RSES. Results: Our results confirm the difference between m…
Problems with variation in teaching/learning Geometry: an example of Chinese Cultural Transposition
2022
This paper discusses some theoretical/methodological observation and some qualitative results coming from a Cultural Transposition experience, implemented in the Italian school context (grade 8), according to the methodology of variation, as one of the most significant problem solving approach in Chinese schools. The framework of the Cultural Transposition and the methodology of variation are presented as an important condition for “decentralizing” the didactic practice from a specific social and cultural context. We argue that looking at different teaching/learning mathematics strategies coming from East-Asia cultures can favor some cultural contaminations at school and allow students to a…
AN EDUCATIONAL EXPERIENCE OF CULTURAL TRANSPOSITION IN PRIMARY SCHOOL: PROBLEMS WITH VARIATION
2016
Since several years, politicians, researchers and educators from different countries are debating on possible reasons for the success of Confucian area students in interactional assessment projects (such as PISA). Starting from the study of teaching practices developed in this East area, in Italy we developed an educational research based on the process of cultural transposition (Mellone & Ramploud, 2015). With this term we mean the process of change that develops considering two or more cultural-educational backgrounds with the aim to maintain their differences without “translating” them from one culture to another, but rather highlighting these in order to review their meaning process…
Existence and multiplicity of solutions for non linear elliptic Dirichlet systems
2012
The existence and multiplicity of solutions for systems of nonlinear elliptic equations with Dirichlet boundary conditions is investigated. Under suitable assumptions on the potential of the nonlinearity, the existence of one, or two, or three solutions is established. Our approach is based on variational methods.
A meshfree approach for brain activity source modeling
2015
Weak electrical currents in the brain flow as a consequence of acquisition, processing and transmission of information by neurons, giving raise to electric and magnetic fields, which are representable by means of quasi-stationary approximation of the Maxwell’s equations. Measurements of electric scalar potential differences at the scalp and magnetic fields near the head constitute the input data for, respectively, electroencephalography (EEG) and magnetoencepharography (MEG), which allow for reconstructing the cerebral electrical currents and thus investigating the neuronal activity in the human brain in a non-invasive way. This is a typical erectromagnetic inverse problem, since measuremen…
Giovanni Meli medico a Palermo tra '700 e '800: il primo dei tre Ricettari
2023
Si discute del primo Ricettario di Giovanni Meli come documento della cultura scientifica sette / ottocentesca a Palermo, esaminando anche questioni filologiche sul latino scientifico del tempo, che avranno importanza per i fini ecdotici.
Penile Enhancement Procedures: Urological And Ethicolegal Issues
2012
Phalloplasty procedures for most men requiring penile augmentation surgery are cos-metic procedures; generally the patients have a normal-sized and fully functional penis but they think that their penis is too small. There are not well defined indications for penile enhancement surgery and, except for the treatment of “micropenis”, there are not established guidelines and the outcome measures for success are still unclear. All penile enhancement techniques often do not reach the expected result and the grade of pa-tient’s satisfaction is frequently poor. Phalloplasty procedures for psychological dys-morfism are not approved by any scientific society and the majority of these procedures are …
Internalizing problems are related to sleep patterns disordered in children affected by primary headache
2017
Introduction: Migraine is a common disorder in children and adolescents, associated with various disorders such as emotions, behavioral problems, and sleep disturbances. Aim of the study is to verify the relationship between psychological problems of cephalalgic patients and sleep disturbances. Materials and methods: 64 subjects (27 females), aged 8-12 years (mean 9.4 years, SD ± 1.03) with primary headache were enrolled. CBCL 6-18 scale and the SDSC scale were used for behavioral screening and for assessing sleep habits. Results: According to the ICHD-III criteria, the distribution of the headache subtype was as follows: headaches without aura (71.87%), headache episodes typical of tensio…
