Considerazioni su Cesare Baronio e la Spagna, tra controversia politica e ricezione erudita
No full textThe study is focused on the complex relationship within Cesare baronio and the Spanish Monarchy, in the new political and historical context. As a cardinal, as pope confessor, as author, he had a preminent role in all the most relavant disputes between Rome, Madrid and Paris of the beginning of the 17th cent., when the balances and the alliances inside the the catholicism were changing.

Future trends in paleoseismology: Integrated study of the seismic landscape as a vital tool in seismic hazard analyses
No full textThis paper forms the Introduction to this Special Issue of Tectonophysics, devoted to selected scientific research
presented during events sponsored by the INQUA Subcommission on Paleoseismicity in the past few years. In this
note, we summarize the contents of the contributed papers and use the issues they raise to review the state-of-the-art in
paleoseismology from a Quaternary geology perspective. In our opinion, the evolution of paleoseismological studies in
the past decade clearly demonstrates that in order to properly understand the seismic potential of a region, and to
assess the associated hazards, broad-based/multidisciplinary studies are necessary to take full advantage from the
geological evidence of past earthquakes. A major challenge in future paleoseismic research is to build detailed
empirical relations between various categories of coseismic effects in the natural environment and earthquake magnitude/
intensity. These relations should be compiled in a way that is fully representative of the wide variety of natural
environments on Earth, in terms of climatic settings, Quaternary tectonic evolution, rheological parameters of the
seismogenic crust, and stress environment. For instance, available data indicate that between earthquake magnitude and
surface faulting parameters different scaling laws exist, and they are a function of the local geodynamic setting
(including style of faulting, typical focal depths, heat flow). In this regard, we discuss in some detail the concept of
seismic landscape, which provides the necessary background for developing paleoseismological research strategies. The
large amount of paleoseismological data collected in recent years shows that each earthquake source creates a signature
on the geology and the geomorphology of an area that is unequivocally related with the order of magnitude of its
earthquake potential. This signature is defined as the seismic landscape of the area (e.g., Serva, L., Vittori, E., Ferreli,
L., Michetti, A.M., 1997. Geology and seismic hazard. In: Grellet, B., Mohammadioun, B., Hays, W. (Eds.),

the seismic behavior of faults capable of producing surface faulting and provides a comprehensive approach for the use of
paleoseismicity data in earthquake hazard characterization
Intensity-attenuation relationships for strong Apennines earthquakes: questioning the stability of regression coefficients over time and space based on MCS and ESI scales
No full textThe reliable evaluation of historical earthquakes is pivotal for seismic hazard assessment, and macroseismic observations are the only data available for the estimation of location and magnitude of historical events . Seismic parameters for pre-instrumental earthquakes included in the Italian catalogue (CPTI15, Rovida et al., 2016) are estimated on the basis of well-constrained empirical relations between Io and Mw, and also through dedicated algorithms (i.e., Boxer code; Gasperini et al., 1999; 2010). However, the application of traditional, damage-based macroseismic scales (i.e., MCS – Mercalli Cancani Sieberg; MMI – Modified Mercalli; EMS98 – European Macroseismic Scale) to contemporary earthquakes suffer some limitations such as the saturation at higher degrees and a strong dependence on the spatial distribution of human settlements . Most pertinent for this research, these scales are significantly influenced by the large variability of building vulnerability as a function of age and local economy.
In this sense, the seismic sequence occurred in Emilia Romagna region in 2012 is particularly relevant . Seismic parameters estimated from the MCS and EMS survey do not match those instrumentally recorded or expected from the application of general empirical regressions (e.g., Galli et al., 2012; Graziani et al., 2015). This has been attributed to the concomitant role exerted by the local geologic setting and the characteristics of the building stock, or to overestimated intensity of strong seismic events in the historical catalog. A complementary approach is provided by the ESI07 (Environmental Seismic Intensity) scale. This scale is based solely on Earthquake Environmental Effects (EEEs), which have the significant advantage of A) still increase in their dimensions also close to full scale and B) to respond consistently in time and space, in particular when the study area shows homogeneous structural, lithological and climatic setting (Michetti et al., 2007). The goal of this note is twofold: (i) evaluate the reliability of EEEs attenuation with distance using a preliminary dataset of Italian strong earthquakes with normal kinematics and (ii) pursue the integration of MCS and ESI scales, which results in a more comprehensive picture of the historical and modern seismic events. We focus on the MCS scale, for which a much larger database is available; arguably, the preliminary results described in the following apply also to the other major damage-based scales (Michetti et al., 2004)

Geological Criteria for Evaluating Seismicity Revisited: Forty Years of Paleoseismic Investigations and the Natural Record of Past Earthquakes
No full textThe identification of individual past earthquakes and their characterization in time and space, as well as in magnitude, can be approached in many different ways with a large variety of methods and techniques, using a wide spectrum of objects and
features. We revise the stratigraphic and geomorphic evidence currently used in the study of paleoseismicity, after more than three decades since the work by Allen (1975),
which was arguably the first critical overview in the field of earthquake geology. Natural objects or geomarkers suitable for paleoseismic analyses are essentially preserved
in the sediments, and in a broader sense, in the geologic record. Therefore, the study of these features requires the involvement of geoscientists, but very frequently it is a
multidisciplinary effort. The constructed environment and heritage, which typically are the focus of archaeoseismology and macroseismology, here are left aside. The geomarkers
suitable to paleoseismic assessment can be grouped based on their physical relation to the earthquake’s causative fault. If directly associated with the fault surface
rupture, these objects are known as direct or on-fault features (primary effects in the Environmental Seismic Intensity [ESI] 2007 scale). Conversely, those indicators not in direct contact with the fault plane are known as indirect or off-fault evidence
(secondary effects in the ESI 2007 scale). This second class of evidence can be subdivided into three types or subclasses: type A, which encompasses seismically induced effects, including soft-sediment deformation (soil liquefaction, mud diapirism), mass
movements (including slumps), broken (disturbed) speleothems, fallen precarious rocks, shattered basement rocks, and marks of degassing (pockmarks, mud volcanoes); type B, which consists of remobilized and redeposited sediments (turbidites, homogenites, and tsunamites) and transported rock fragments (erratic blocks); and type C, entailing regional markers of uplift or subsidence (such as reef tracts, microatolls, terrace risers, river channels, and in some cases progressive unconformities).
The first subclass of objects (type A) is generated by seismic shaking. The second subclass (type B) relates either to water bodies set in motion by the earthquake (for the sediments and erratic blocks) or to earthquake shaking; in a general way, they all relate to wave propagation through different materials. The third subclass (type C) is mostly related to the tectonic deformation itself and can range from local (next to the causative fault) to regional scale.
The natural exposure of the paleoseismic objects—which necessarily conditions the paleoseismic approach employed—is largely controlled by the geodynamic setting.
For instance, oceanic subduction zones are mostly submarine, while collisional settings tend to occur in continental environments. Divergent and wrenching margins may occur anywhere, in any marine, transitional, or continental environment.
Despite the fact that most past subduction earthquakes have to be assessed through indirect evidence, paleoseismic analyses of this category of events have made dramatic progress recently, owing to the increasingly catastrophic impact that they have on human society
Seismic Landscape of the Monferrato Arc
No full textThe Emilia and Lombardia 2012 seismic sequence (two main shocks of Mw ca. 6.0) revamped once again the
scientific debate about the seismic hazard posed by Quaternary tectonic structures of the Po Plain foredeep (e.g., Serva,
1990; Boccaletti et al., 2004; Picotti and Pazzaglia, 2008; Michetti et al., 2012; Galli et al., 2012). The W sector of the
foredeep represents in particular the area with most controversial interpretation in terms of active tectonics and seismic
potential. For instance, in the ITHACA catalogue of capable faults the Monferrato Arc is regarded as a seismogenic
structure with potential for surface faulting earthquakes; while in the DISS database the W Lombardia and Piemonte
are essentially interpreted as areas lacking any evidence of active faulting and seismic sources with Mw > 5.5. In order
to attack this issue, we conducted field investigation, geomorphic analyses and the revision of the large existing
database of seismic reflection profiles covering the study area in order to assess the seismic landscape of the Monferrato
Arc. Our investigations confirm that the Late Quaternary landscape evolution of the South-Central Piemonte is the
result of the interaction between active tectonics and widespread phenomena of river avulsion and piracy, which
affected virtually the whole Piemonte and nearby Liguria region. In fact, these dramatic changes in the regional
drainage network are controlled by shortening and thrust fault growth, which started during Oligo-Miocene times and is
still active with visible deformation rates (Carraro et al., 1995). The development of the Apennines buried thrust fronts
since Miocene give rise to the progressive uplift of the Monferrato and Torino Hills, translated above the depositional
sequences of the Po Plain foredeep. The continuing deformation and displacement of the surficial deposits up to at least
the Mid Pleistocene allow us to regard the buried structures of the Monferrato Arc as potentially capable faults (IAEA,
2010). Therefore, based on the available data, the regional seismotectonic framework for the W Po Plain is comparable
with the one already recognized in the Emilia Arc or in the LombardiaVeneto S Alps (Modena 2012, Brescia 1222,
Verona 1117). The seismic landscape of the Monferrato Arc thus includes potential surface faulting earthquakes, with
M max in the order of 6.0 – 6.5 (Michetti et al., 2012), and accompanied by considerable liquefaction and earthquake
environmental effects
Nonlinear dynamics in real economy and financial markets: The role of dividend policies in fluctuations
No full textThis paper investigates how dividend policies may influence the creation and propagation of cycles between real economy and financial markets. We focus on the effect of a constant dividend policy on the stability of the aggregate economy, by means of a discrete dynamical framework in which managers, individuals and financial mediators coexist. We show the counter-intuitive effect of the dividend payout ratio: in a developed economy, an increase in dividends leads to a lower stock price level due to the cross-feedback effect between markets. Moreover, in non-developed economies the choice of managers and individuals may not influence the propagation of fluctuations, while in developed economies, high payout ratios and high sensitivity to market trends trigger a cross-feedback effect between the two markets that amplifies their volatility and drags the whole economy into fluctuations and cycles
Specific binding sites for S-100 protein in isolated brain nuclei
No full textIsolated brain nuclei possess binding sites for S-100 protein. The interaction of S-100 with these sites is specific and time-, temperature-, and Ca+ -dependent. The profile of the (125)I-labelled S-100 binding inhibition is biphasic, displaying a high-affinity component and a low-affinity component. The S-100 binding to brain nuclei is largely irreversible, probably owing to the formation of a tight complex between the protein and its nuclear binding sites. The S-100 binding to brain nuclei is in most aspects similar to that to synaptosomal membranes. Several lines of evidence indicate, however, that the S-100 binding to nuclei is not due to contamination of these structures with plasma membranes. Isolated liver nuclei do not possess the high-affinity component of S-100 binding
