L'Italia nella topografia finzionale del "Wilhelm Tell" di Friedrich Schiller
No full textNel finale dell'opera Tell indica a Parricida la via dell'Italia come un percorso di possibile redenzione. La topografia del viaggio verso il Sud è resa in termini spirituali, con un'insistenza particolare su aspetti molto vicini all'ambito delle passioni tragiche. Il saggio indaga questa costellazione servendosi anche degli strumenti ermeneutici propri del "topographical turn
“Etica della conoscenza”. La poesia antiretorica di Ernst Blass
Full text linkErnst Blass appartiene al gruppo dei fondatori del movimento espressionista in Germania, ma la sua poetica detiene una cifra di originalità resistente a definizioni di
scuola. La lirica di Blass si distingue per la fedeltà a una misura sobria e antiretorica,
disinteressata ad anticipazioni visionarie del futuro e volta, pur nella sua essenzialità,
alla costruzione di un modello generale di comprensione della realtà

Richard Schaukals Kulturkritik zwischen Elitismus und Ressentiment
No full textRichard Schaukal incorpora aspetti paradigmatici ed esemplari quanto al rapporto tra vita e forme nella cultura estetica del fine secolo. Rappresentante dapprima di un culto intransigente della distinzione formale, nel quale si riversano evidentemente anche frustrazioni e bisogni di ordine sociale, si dedica poi, a partire dagli anni Venti del '900, a pubblicazioni di orientamento nazionalistico, segnate da elementi profondamente conservatori e regressiv
Review of immediate cardiac response in intertidal gastropods limpets at varying temperature, salinity and air exposure
No full textIn 1990 Depledge and Andresen developed a #eld/laboratory, non-invasive technique
to monitor the immediate response of cardiac activity in bivalves. Since then,
several researchers have experienced and tested the variability of heart beat rate
(HBR)and of associated metabolic rates under dierent hypothesis.
In intertidal Mediterranean and tropical limpets, the decrease in metabolic rate with
a decrease in salinity was dierent degrees of salinity
!uctuation in their respective microhabitats. Intertidal limpets respond to temperature
increases, increasing HBR and metabolic rate. Furthermore, when reaching the highest
temperature experienced in #eld, HBR shows extreme responses as secondary bradicardia.
Finally, when exposed to dry/saturated air cycles, lower shore intertidal limpets
show regular alternation of normal HBR and acardia, whilst the upper shore limpet
showed transient acardia only during exposure to dry air. In conclusion, it was demonstrated
that dierent !uctuations
of the physical environment experienced by individuals inhabiting di$erent levels
of the shore
Heart beat rate of invasive Brachidontes pharaonis with respect to the native Mytilaster minimus within the Mediterranean Sea at varying salinites
No full textChanges in heart beat rates (HBR) of Brachidontes pharaonis (an invasive Lessepsian species) and Mytilaster minimus (a
native Mediterranean species) in response to changes in salinity values from brackish (20) to extreme hyper-saline (75)
were investigated both in situ and in the laboratory. The two species displayed different responses to varying salinity, with
clear differences in HBR observed between groups investigated at different salinities and between groups originating from
different environments. The native species, adapted to narrow salinity changes as those observed in the superficial waters of
the Mediterranean Sea, showed signs of stress at salinities slightly above 37 (in the range 37–45). On the other hand, the
invasive species displayed clear signs of stress only at salinities over 45 and exhibited heart activity even under hyper-saline
conditions (i.e. salinity = 75). These results indicate that the Lessepsian species has the potential to invade most of the transitional
environments across the entire Mediterranean basin. We therefore stress the need of including Brachidontes
pharaonis in all coastal monitoring programmes assessing the actual and potential spreading of alien species in the Mediterranean
region
