Dallo scavo alla mostra. Le indagini sul sito altomedievale di S. Agata Bolognese
No full textNel 1994 durante gli scavi per l'allestimento di un settore della discarica intecomunale Nuova Geovis S.p.A. in loc. Crocetta a Sant'Agata Bolognese (Bo), sono venuti alla luce i resti di un villaggio altomedievale databile al X-XI secolo d.C., costituito da un nucleo abitato con strutture insediative e aree di produzione (focolari, officina per la lavorazione dei metalli, ecc.) circondato da un ampio fossato e da un terrapieno interno. Il presente volume, oltre a poter essere un utile quaderno didattico, illustra e riassume quanto svolto durante l'intervento archeologico di scavo e le metodologie adottate (gli operatori, il cantiere, le campagne di scavo, lo scavo stratigrafico, i rilievi, la strumentazione, la documentazione di scavo), le discipline utilizzate per la datazione (termoluminescenza, C14, dendrocronologia) e l'archeobiologia per la ricostruzione del contesto vegetale (attraverso l'archeopalinologia, archeocarpologia, archeoxilo-antracologia) ed animale (archeozoologia). L'ultima sezione è invece dedicata al restauro e alle relative tecniche per il recupero di ceramica, vetri e metalli, legni

La vite maritata. Storia, cultura, coltivazione ecologia della piantata nella pianura padana
No full textIl volume illustra la storia della coltivazione della vite e della cultura del vino nell'area Mediterranea attraverso le fonti storiche, i documenti e le testimonianze archeobotaniche. Inoltre vengono approfonditi gli aspetti legati alla diversa tipologia di piantata nel Bolognese e in particolare nell'area di Bentivoglio e di San Giovanni in Persiceto con testimonianze e documenti. Infine viene illustrata la trasformazione del paesaggio agrario e delineato il futuro della piantata

The economic crisis as a trigger of convergence? : short-time work in Italy, Germany and Austria
No full textIn all European countries, emergency policy measures have been introduced in order to counteract the
employment consequences of the economic crisis. In the context of variously composed anti-crisis
packages, many European countries have used Short-Time Work (STW) schemes, that is measures
to subsidize a temporary reduction in working time intended to maintain an employment relationship.
This article focuses on the issue of whether the economic crisis has spurred any convergence in
the use of STW in three social-insurance countries – Austria, Germany and Italy – or whether
policy change has rather occurred in a path-dependent fashion. In order to do so, the article also
adopts a systemic approach, focusing on relationships of complementarity or functional substitution
and equivalence among the various schemes comprising income maintenance systems to tackle the
risks of partial or total unemployment

Effects of long-term light acclimation on Photosystem II functional antenna size and excitonic connectivity in Selaginella martensii.
No full textLycophyte division is composed of ancient vascular plants that diverged from euphyllophyte lineage ca. 400 million years ago. Among these, Selaginella martensii Spring has evolved to inhabit shade environments of tropical-equatorial rainforests. However, this plant is also able to acclimate efficiently to light regimes as different as deep shade and full sunlight (Ferroni et al. 2016, 2021). Such characteristic reveals a marked flexibility of the photosynthetic machinery in response to the light availability, but the underlying structural and dynamic acclimation features have been clarified only partially. In fact, differently from most seed plants, S. martensii is unable to modulate the content of Photosystem II antenna complexes (LHCII), which remains constant from deep shade to full sunlight regime, while the ratio between PSII and PSI decreases. In order to clarify the light acclimation features in S. martensii under deep-shade (L), intermediate shade (M) and full sunlight (H), we analyzed some functional aspects of light harvesting and electron transport after the plants' exposure to dark for 20 minutes, far red (FR) light for 20 minutes and moderate light for 1 hour. The analysis was performed using a HandyPEA (Hansatech, UK) fluorometer, which allowed us to calculate the JIP-test parameters. Among these, we particularly focused on ABS/RC, i.e. the functional antenna size of a PSII unit (Stirbet and Govindjee 2011). We also used the fluorescence transients to calculate the PSII excitonic connectivity parameters, which describe the probability of excitation transfer between different PSII units (Stirbet 2013). Our results suggest that the acclimation to different light regimes influences both PSII functional antenna size and PSII connectivity, but the direction of changes apparently contrasted with expectations. On one hand, the PSII antenna size was only slightly variable from L to H plants. On the other hand, PSII connectivity was in general far lower when compared to common values reported for seed plants. Especially H plants reported connectivity values close to 0, suggesting a "puddle" organization of PSII
