MOTOR COORDINATION AND RELATED FACTORS IN CHILDREN, EFFECTS OF A TEACHING INTERVENTION
The teaching of motor competencies requires attention to the
psycho-pedagogical and didactic models adopted, in relation to the
contexts and needs of the students. The study evaluates the effects
of teaching styles on motor development, self-efficacy and
satisfaction in primary school children. The results show significant
post-intervention improvements. Production styles promote the
integration of motor, cognitive, emotional and social aspect

Temporary migration and wages of Ph.D.s. Stay longer or come back sooner?
This paper examines the wage implications of temporary migration for two cohorts of Italian Ph.D.s. Special attention is given to the duration of the international experience, its contribution to earned wages and the selectivity of returnees. Returnees are found to be a
self-selected group whose unobservable characteristics are simultaneously associated with both higher wages and a higher propensity to migrate. Moreover, we find positive returns for those who stay longer and negative returns for those who come back sooner. The results are confirmed in several robustness and sensitivity checks
Innovative Building Materials Containing Post-Consumer Plastics: A Rewarding Example of Circular Economy in Construction
Circular Economy, which it is among the priorities of the European Commission, is defined as an economy in which the value of products, materials and resources is maintained for as long as possible and the production of waste is reduced to minimum. Keeping in mind the impact on the environment caused on the one hand by post-consumer plastic waste and on the other hand by production processes of concrete,it is possible to find a solution able, at least partly, to mitigate these two issues. Following the principles of the circular economy, in fact, it is possible to reuse post-consumer plastic waste as fine aggregates in concrete: in this way, post-consumer plastic from waste becomes a resource; at the same time, the use of other natural resources is limited, such as the minerals traditionally used as aggregates in concrete. However, this virtuous solution still presents some problems to study and solve: this work aims to illustrate some of these issues, and provides indications on the aspects to be analyzed and solved
Observation of ttbar Production in Pb+Pb Collisions at sqrt(sNN) = 5.02 TeV with the ATLAS Detector
Top-quark pair production is observed in lead-lead (Pb+Pb) collisions at sqrt(sNN)=5.02 TeV at the Large Hadron Collider with the ATLAS detector. The data sample was recorded in 2015 and 2018, amounting to an integrated luminosity of 1.9 nb-1. Events with exactly one electron and one muon and at least two jets are selected. Top-quark pair production is measured with an observed (expected) significance of 5.0 (4.1) standard deviations. The measured top-quark pair production cross section is sigma_ttbar = 3.6 +1.0-0.9(stat) +0.8-0.5(syst) mub, with a total relative uncertainty of 31%, and is consistent with theoretical predictions using a range of different nuclear parton distribution functions. The observation of this process consolidates the evidence of the existence of all quark flavors in the preequilibrium stage of the quark-gluon plasma at very high energy densities, similar to the conditions present in the early Universe
