No full textRecent work to restore and set up the materials exhibited at the Museo della Specola of the University of
Bologna provided an opportunity to review the history of two important German instruments from the mid-nineteenth
century, an Ertel & Sohn meridian circle and a Steinheil refractor. Purchased by the Directors of the Bologna
Observatory to revitalise local astronomical research, which had gradually declined over the years, both instruments
have intriguing histories because, despite the fact that they were essentially underused, they also contributed to two
important research projects. Lorenzo Respighi used one of them—the Ertel & Sohn meridian circle—for an
experiment in physical optics related to the debate on whether light was undulatory or corpuscular, and it was
essentially a forerunner of ‘water-filled telescopes’. The other, a Steinheil refractor to which a Tauber spectroscope
was attached, was the largest and most important instrument used by the Italian expedition to India, organised by
Pietro Tacchini to observe the transit of Venus across the Sun in 1874
Telecollaboration and the Remediation of Intercultural Communication
No full textThis paper illustrates the phases of a research project called Intercultural Telecollaboration that is based on the remediation of linear written discourse via the integration of digital tools. The aim of this study is to discuss the pedagogical use of hypermedia to promote Telecollaboration, which represents one of the greatest achievements of Web applications thus far focused on the improvement of foreign language learning and intercultural competence. Ten Italian high-school students of English and ten American intermediate-level students of Italian were paired up and interconnected online in order to use their L2s to discuss several conversational topics regarding their sociocultural backgrounds. Participants were encouraged to improve their mutual intelligibility through e-partnering, that consists in the voluntary exchange of selective corrective feedback. Moreover, a pre- and a post-survey were conducted to collect qualitative data about the students' experience in taking part in the project

No full textThe paper focuses on information books on history and their translation, thereby examining the changes occurred in the translating process. If popularizing is an act of “mediation between expert and lay audience”, this “hybrid genre”, at the crossroad between informative and entertaining discourses, can be said to create a multifaceted and multimodal type of mediation that needs to meet children’s supposed cognitive abilities and background knowledge. In particular, the analysis shows that historical information books undergo a further process of “re-mediation”, underlying a different idea of popularisation and a different idea of readership. In point of fact, the shifts between the source texts and the target texts reveal an unexpected for of “complexification” through which the translations turn out to be more accurate than their respective originals. Therefore, the translations imply the idea that this “informal learning”, even if it is optional, needs to be detailed and exhaustive
