The Bologna Process in Italy
No full textItaly was among the promoters of the Bologna Process, and the early adopters of the reform. If one looks at its impact on the formal structure of curricula and study programmes, the reform undertaken under the Bologna banner seems to have been one of the major educational reforms ever achieved in Italy. The paper describes how the Bologna Process has unfolded in Italy, looking at the reasons why a reform that for long eluded Italian policymakers and higher education managers finally succeeded in this case. The object is approached from the point of view of the contemporary theories of institutional change, looking at the actors and interactions who made this reform possible in spite of strong oppositions. In fact, it was a series of contingent events that weakened the balance of powers governing Italian HE, thus making institutional change possible

La coltivazione del melograno (Punica granatum L.) negli insediamenti fenici d'Occidente: il contributo dell'archeobotanica
No full textIn questo contributo si propone un quadro aggiornato sulle testimonianze della coltura del melograno (Punica
granatum L.) nelle aree del Mediterraneo centrale e occidentale interessate dalla colonizzazione fenicia e punica.
Sebbene la scarsità dei dati archeobotanici disponibili per alcune regioni di questo ambito geografico abbia
spesso costituito un limite per la ricostruzione dei tempi e dei modi di propagazione della pianta, recenti scoperte
di micro e macroresti vegetali (soprattutto semi e pollini) in alcuni importanti insediamenti coloniali sembrano
gettare nuova luce sul ruolo fenicio e punico nella sua diffusione.This article proposes an updated analysis of the spread of pomegranate cultivation (Punica granatum L.)
throughout the central and western Mediterranean area interested by the Phoenician and Punic colonization.
The scarcity of archaeobotanical data in some regions of this geographical context has often prevented archaeologists
from reconstructing how and when the pomegranate spread; nevertheless, recent discoveries of plant
remains (seeds and pollen principally) from important colonial settlements seem to throw new light on the
Phoenician and Punic role in its diffusion
Wind and earthquake protection of cable-supported bridges
No full textThis paper deals with control strategies for the mitigation of unwanted vibrations in typical medium and long-span cable-supported bridges, aiming to underline general observations and side effects related to the adoption of different control strategies. Two finite-element models of medium and long-span bridges, namely a suspension and a cable-stayed bridge, are developed for simulating the structural response under wind and earthquake excitation. Passive and semi-active control strategies are then implemented in the models for mitigating dynamic effects. Such control schemes have been designed for wind excitation on the suspension bridge, and seismic excitation on the cable-stayed bridge. Attention is initially focused on high-intensity loading conditions, having a low probability of occurrence. The same control strategies and arrangements have then been re-assessed by changing the input intensity; in addition, a cross-check has been performed by addressing earthquake actions on the suspension bridge and wind forces on the cable-stayed bridge. The results have been also analysed in terms of indirect effects, such as fatigue damage
Paleoclimatic significance of the last interglacial paleosols of the Baratti Gulf cliff section (southern Tuscany, Italy)
No full textPaleopedological studies of littoral deposits provide potentially useful tools for understanding the response
of the sedimentary systems to tectonics (i.e. uplift and subsidence) versus climate and sea- level changes
occurred along the Mediterranean coasts, during the late Quaternary. An example is reported from the
Baratti Gulf cliff section formed during the last interglacial cycle. The upper Pleistocene-Holocene
succession of the Baratti Gulf exhibits significant vertical changes from marine to continental deposits,
marked by several erosional discontinuities. Four stacked transgressive units capped by buried weathering
profiles have been recognized (Cortemiglia et a!., 1983). These transgressions, recorded by foreshore to
upper shoreface deposits (Sarti eta!., 2005), should correspond to four sea-level high-stands correlated with
MIS 5c, MIS Sa, MIS 3 and the transition of MIS 2-1, respectively (Mauz, 1999). A continental deposit of
aeolian origin with an oligotypical mollusc assemblage separates the younger two transgressive units from
the older two. Tentatively this layer has been correlated with MIS 4 (Sarti et a!., 2005).
A detailed geopedological survey (mainly micromorphological) was conducted on selected vertical
profiles, in order to improve the stratigraphic and depositional history of the Baratti Gulf deposits. Fieldbased
profile descriptions of paleosols evidenced that they are incomplete (absence of topsoil horizons),
and deeply truncated by erosion. Moreover, the paleosols show a different degree of pedogenic expression,
progressively more intense from younger to older paleosols. Their major pedogenic features and formative
processes occurred polycyclically, attesting distinct and relict pedogenetic phases not in equilibrium with
the present- day environmental condition. Each paleosols developed in a moist, warm and forest
environment, and at the end of each pedogenetic cycle a decline of the vegetation cover associated to a
climatic deterioration caused a general retrogradation of the soil properties (polygenetic soil evolution).
The effect of "glacial phases" is mostly reflected in erosion and soil truncation processes recorded by the
bounding surfaces at the top of the transgressive cycles. Following the previous considerations, the
transgressive events probably took place at the onset of the warm-humid interglacial periods while the
subsequent subaerial exposure and pedogenesis of the marine-coastal deposits represent the closing events
of the interglacial cycles.
The paleosols of the Baratti Gulf cliff section record regional and global climatic events providing
information into the tectono-sedimentary and climate evolution of the area during the late Pleistocene. This
study may support the knowledge of the variability of the most important climatic events during last
interglacial soil evolution on the Mediterranean area
