PROGRAM RANE INTERVENCIJE NAMENJEN RODITELJIMA PREVREMENO RODENE DECE”(EARLY INTERVENTION PROGRAM FOR PARENTS OF PREMATURE INFANTS. EFFECTS OF A PSYCHOLOGICAL SUPPORT IN THE FIRST WEEKS OF LIFE ON CHILD DEVELOPMENT AT 6 AND 12 MONTHS)
No full textLow birth weight preterm children are at-risk for developmental difficulties, cognitive and emotional disabilities. An intervention program, aimed to ameliorate parents–infant communication, involved 11 low birth weight infants, without birth complications, from low socio-cultural level families. The intervention consisted in: 1) psychological support to improve parents’ communication and caregiving during the first weeks of life; 2) follow-up assessment at 6 months on the parent-infant interaction; 3) follow-up assessment at 12/18 months on the Mother-Infant attachment. The general hypothesis was that ameliorating the quality of parents-newborn interaction in the first weeks of life, especially reinforcing the imitation, could predispose the newborn to develop a secure attachment bond. The mother-infant communication improved in all cases at first step, but only 3/11 children were secure-attached at 12/18 months. The same three children had the father regularly attending the encounters, supporting the mothers, thus indicating a good quality in the marital relationship. Early parent-infant communication can be improved with a psychological support, but the quality of the marital relationship seems to be more related to a long-term effect represented by the secure attachment

Effect of weak disorder in the fully frustrated XY model
No full textThe critical behaviour of the fully frustrated XY model in the presence of weak
positional disorder is studied in a square lattice by Monte Carlo methods.
The critical exponent associated to the divergence of the chiral correlation
length is found to be already at very small values of
disorder. Furthermore the helicity modulus jump is found larger than the
universal value expected in the XY model
Plasmons in topological insulator cylindrical nanowires
No full textWe present a theoretical analysis of Dirac magnetoplasmons in topological insulator nanowires. We discuss
a cylindrical geometry where Berry phase effects induce the opening of a gap at the neutrality point. By
taking into account surface electron wave functions introduced in previous papers and within the random phase
approximation, we provide an analytical form of the dynamic structure factor. Dispersions and spectral weights
of Dirac plasmons are studied with varying the radius of the cylinder, the surface doping, and the strength of an
external magnetic field. We show that, at zero surface doping, interband damped plasmonlike excitations form
at the surface and survive at low electron surface dopings (∼1010 cm−2). Then, we point out that the plasmon
excitations are sensitive to the Berry phase gap closure when an external magnetic field close to half quantum flux
is introduced. Indeed, a well-defined magnetoplasmon peak is observed at lower energies upon the application
of the magnetic field. Finally, the increase of the surface doping induces a crossover from damped interband to
sharp intraband magnetoplasmons, which, as expected for large radii and dopings (∼1012 cm−2), approach the
proper limit of a two-dimensional surface
Intervention Strategies for children and Adolescent with Disorders: from Intrapsychic to Transactional Perspective
No full textEffects of rearing conditions on skeletal anomalies typology and frequency in gilthead seabream Sparus auratus juveniles.
No full textThis study analyzed different lots of gilthead seabream juveniles outcoming from the same egg batch, but reared under different (intensive vs semi-intensive) conditions aimed at: (1) quantitatively and qualitatively analyzing whether differences in skeletal elements (shape and number) arise; (2) to investigate if a relationship between skeletal bone tissue/ossification and some environmentally-induced malformation exists; and (3) identifying the best practices for seabream larval rearing in order to obtain lower deformity rates.
A total of 981 reared juveniles of gilthead seabream were analysed, among which 721 were from a commercial hatchery located in Northern Italy (Valle Figheri, Venice, Italy), and other 260 were obtained from the Hellenic Center for Marine Research (Iraklion, Crete, Greece). These individuals were from 4 different eggs batches (Groups 1-4), for a total of 10 different lots. Each egg batch/group was split after hatching in two lots, and reared with two different methodologies, intensive and semi-intensive rearing. Some lots (Group 3: INIT19, INIT18, LVIT04, LVIT05) were sampled at two different ages. Semi-intensive lots were reared under two different methodologies: Large Volumes (sensu Cataudella et al., 2002)and Mesocosm (sensu Divanach and Kentouri, 2000). All the samples were analyzed (whole mount staining) for skeletal anomalies and variation in meristic counts.
Lower severe skeletal anomalies incidences and meristic counts variability were found in all the semi-intensively reared lots, with significant higher capacity of Large Volumes of ameliorating anatomical quality of juveniles than Mesocosms.
In all the semi-intensive lots, the bones undergone intramembranous ossification showed constant lower incidences of malformations whilst endochondrally and perichondrally ossifying skeletal elements did not always exhibit the same clear pattern.
