No full textEricaria bosphorica (Sauvageau) Serio & G. Furnari comb. nov. Cystoseira bosphorica Sauvageau, Bulletin de la Station biologique d’Arcachon 14: 413, 529 (Sauvageau 1912). Finally, the particular habitat of the Porto Palo population of E. giacconei is noteworthy. As stated, that species was found in association with a bioconstruction of Sabellaria alveolata (Linnaeus, 1767) (Annelida, Polychaeta) (Fig. 5A, B), first observed in 2018 (Sanfilippo et al. 2020). Periodic observations conducted in the last few years showed that the E. giacconei community is expanding (it currently covers an area of about 100 m 2 with a specific coverage of 80%). The relationship between S. alveolata and E. giacconei seems to be not casual but synergistic, and the two species intergrow, with the perennial portion of E. giacconei thalli seemingly protected by the surrounding permeable agglutinated worm structure (Fig. 5B). Further studies are underway to follow the evolution of the bioconstruction and E. giacconei population, ascertain the nature of main species relationships and assess the biodiversity of this distinctive association.Published as part of Serio, Donatella & Furnari, Giovanni, 2021, Ericaria giacconei sp. nov.

Il metodo Montessori come strumento di pace. Percorsi di educazione all’affettività
No full textScopo del contributo è quello di individuare le aree tematiche attorno alle quali è stato pensato e costruito il progetto "Play to be a player: learn for your life", per dimostrare la centralità dei suddetti temi nel modello pedagogico montessoriano che, primo tra tutti, ha focalizzato l'attenzione sull'opportunità di utilizzare in ambito scolastico soluzioni pedagogico-didattiche innovative per intervenire, dopo averli individuati, sui comportamenti antisociali

No full textThe Impact of r-g on Euro-Area Government Spending Multipliers
No full textWe compute government spending multipliers for the Euro Area contingent on the interest-growth differential, the so-calledr-g. Whether the fiscal shock occurs when r-g is positive or negative matters for the size of the multiplier. Median estimates vary conditional on the specification, but the difference between multipliers in the negative and positive r-g regimes differs systematically from zero with very high probability. Over the medium run (5 years), median cumulated multipliers range between 1.13 and 1.77 when r-g is negative, and between 0.54 and 1.26 when r-g is positive. We show that the results are not driven by the state of the business cycle, the monetary policy stance, or the level of government debt, and that the multiplier is inversely correlated with r-g. The calculations are based on the estimates of a factor-augmented interacted panel vector-autoregressive model. The econometric approach deals with several technical problems highlighted in the empirical macroeconomic literature, including the issues of fiscal foresight and limited informatio
