Palaeoclimatol. Palaeoecol. 276, 196-205) (hereafter Getal09) use the sequence stratigraphic record of a Cenomanian-Coniacian base-of-slope succession, exposed in the Morrone mountain of central Italy, to calibrate the sea-level history inferred from the adjacent Lazio-Abruzzi carbonate platform. The episodes of sea-level fall recorded by this carbonate platform and slope in the western Tethys are said to coincide with episodes of global cooling and sea-level fall recorded in the New Jersey margin (Miller, K.G., Sugarman, P.J., Browning, J.V., Kominz, M.A., Hernández, J.C., Olsson, R.K., Wright, J.D., Feigenson, M.D., Van Sickel, W., 2003. Late Cretaceous chronology of large rapid sea-level changes: glacioeustasy during the greenhouse world. Geology 31, 585-588). On the basis of this correlation, Getal09 claim that the Late Cretaceous sea-level history of the Lazio-Abruzzi carbonate platform was controlled by glacio-eustatic fluctuations.This conclusion conflicts with a wealth of published data supporting the view that the major unconformities in the Cretaceous carbonate platforms of central-southern Italy were controlled by regional tectonics.We will show how the sea-level history of the Lazio-Abruzzi carbonate platform proposed by Getal09, and its correlation with the base-of-slope section, hinge on a misrepresentation of the chronostratigraphic resolution attainable with biostratigraphy in shallow-water carbonate facies. We will also show how, contrary to what claimed by Getal09, the age-model for their base-of-slope section does not support the correlation with the New Jersey margin sequences. Finally, we will argue that, in Upper Cretaceous carbonate platforms, the integration of bio- and chemostratigraphy can greatly improve stratigraphic resolution and chronostratigraphic correlation. This is a prerequisite for using the shallow-water record to test the hypothesis of global glacio-eustatic fluctuations in the Cretaceous greenhouse. © 2010 Elsevier B.V

No full textOn Complex Solvmanifolds and Affine Structures
No full textLet G be a complex, connected, simply connected, solvable Lie group and U a discrete
uniform subgroup. The authors give a sufficient condition, in terms of structure constants of the Lie algebra of G, under which the complex solvmanifold M = G/U has an analytic affine
structure (i.e., there is an atlas on M whose transition functions are affine). The condition is
fulfilled for all solvmanifolds M = G/U of dimension ≤ 5
L'attrattività territoriale per la popolazione anziana
No full textNegli ultimi decenni tutti i Paesi più sviluppati sono stati interessati da un forte processo di invecchiamento dovuto essenzialmente all’aumento della speranza di vita e al rallentamento delle nascite, con conseguente aumento della popolazione con età superiore ai 65 anni e una diminuzione della forza lavoro che potrebbe avere gravi effetti per l’economia.
Infatti, se nella metà del ventesimo secolo gli anziani costituivano poco più del 4% della popolazione mondiale, nel 2020 tale cifra ha superato il 9% (World Bank, 2021a), e secondo le stime del Dipartimento degli Affari Economici e Sociali dell’ONU nel 2050, il numero degli over 65 rappresenterà il 17% della popolazione del pianeta. Tuttavia, come afferma l’Organizzazione Mondiale della Sanità, una gran parte degli ultrasessantacinquenni sono persone in buona salute fisica e mentale, con un potere di acquisto elevato e una notevole propensione di spesa. Inoltre, il cambiamento della situazione personale, familiare, sociale e la maggiore disponibilità di tempo libero comporta anche una maggiore attitudine alla mobilità spaziale tanto che al giorno d’oggi costituiscono il 12% dei flussi migratori mondiali. In tale conteso, una significativa percentuale del movimento complessivo di pensionati (14%) si svolge tra i Paesi europei (United Nations, 2021).
In base a queste indicazioni si è affermata progressivamente una visione diversa dell’età avanzata. Gli anziani non sono più considerati soltanto un effetto frenante sul potenziale di crescita dell’economia, un problema per la sostenibilità dei sistemi pensionistici e assistenziali e per la maggiore pressione fiscale sulla popolazione attiva. Lo stile di vita e le esigenze dei nuovi “giovani anziani”, attivi e in buona salute, già costituiscono una grande opportunità per lo sviluppo economico grazie alla crescente domanda di beni e servizi sia di quelli compresi nei settori produttivi tradizionali sia di quelli più innovativi. Secondo uno studio della Commissione europea, già nel 2015 la cosiddetta silver economy rappresentava il 18% del PIL mondiale, e tale valore continua ad aumentare.
Molti governi, perciò, hanno elaborato strategie per intercettare i flussi migratori di pensionati, valorizzando dotazioni naturali, culturali e, in particolare, offrendo favorevoli condizioni fiscali per i redditi prodotti all’estero. In questo capitolo si esamineranno i fattori di attrattività del territorio per la popolazione anziana e gli impatti positivi che gli immigrati pensionati possono apportare alla nuova residenza

No full textEducation and Training in St.Lucia: A Partially Annotated Bibliography
No full textThis bibliography on “Education and Training in St. Lucia” has been specifically prepared for the UWI School of Continuing Studies’ St. Lucia Country Conference. An attempt has been made to be as comprehensive as possible, but because of the weak bibliographical coverage of the literature of the region, important items may have been omitted. This is especially true for policy documents emanating from official sources. It covers all aspects of education and training in St.Lucia including distance education, educational finance,health and family life education and educational reform
Petunia Performance Under Application of Animal-Based Protein Hydrolysates: Effects on Visual Quality, Biomass, Nutrient Content, Root Morphology, and Gas Exchange
No full textSustainable plant production practices have been implemented to reduce the use of synthetic fertilizers and other agrochemicals. One way to reduce fertilizer use without negatively impacting plant nutrition is to enhance crop uptake of nutrients with biostimulants. As the effectiveness of a biostimulant can depend on the origin, species, dose, and application method, the aim of this research was to evaluate the effect of a commercial animal-based protein hydrolysate (PH) biostimulant on the visual quality, biomass, macronutrient content, root morphology, and leaf gas exchange of a petunia (Petunia × hybrida Hort. “red”) under preharvest conditions. Two treatments were compared: (a) three doses of an animal-based PH biostimulant: 0 (D0 = control), 0.1 (D0.1 = normal), and 0.2 g L–1 (D0.2 = high); (b) two biostimulant application methods: foliar spray and root drenching. The dose × method interaction effect of PH biostimulant on the plants was significant in terms of quality grade and fresh and dry biomass. The high dose applied as foliar spray produced petunias with extra-grade visual quality (number of flowers per plant 161, number of leaves per plant 450, and leaf area per plant 1,487 cm2) and a total aboveground dry weight of 35 g, shoots (+91%), flowers (+230%), and leaf fresh weight (+71%). P and K contents were higher than in untreated petunias, when plants were grown with D0.2 and foliar spray. With foliar spray at the two doses, SPAD showed a linear increase (+21.6 and +41.0%) with respect to untreated plants. The dose × method interaction effect of biostimulant application was significant for root length, projected and total root surface area, and number of root tips, forks, and crossings. Concerning leaf gas exchange parameters, applying the biostimulant at both doses as foliar spray resulted in a significant improvement in net photosynthesis (D0.1: 22.9 μmol CO2 m–2 s–1 and D0.2: 22.4 μmol CO2 m–2 s–1) and stomatal conductance (D0.1: 0.42 mmol H2O m–2 s–1 and D0.2: 0.39 mmol H2O m–2 s–1) compared to control. These results indicate that application of PH biostimulant at 0.2 g L–1 as foliar spray helped to achieve extra-grade plants and that this practice can be exploited in sustainable greenhouse conditions for commercial production of petunia
