Sommario/riassunto

Chiral materials have been studied in the Department of Chemistry at the University of Virginia for applications in areas like asymmetric catalysis, enantioselective fluorescent sensing, and optical/electrical materials. Optically active 1,1'-binaphthyl molecules are used to build novel chiral polymers, dendrimers, macrocycles, and acyclic molecules. 1,1'-Binaphthyl molecules are chosen because of their remarkably stable chiral configuration as well as their high asymmetric inductions in many processes. In this book, both the fundamental knowledge about the 1,1'-binaphthyl molecules and the sy

Sommario/riassunto

Exploring the intersections between migration and tourism in the Mediterranean, this book is the result of extensive ethnographic research carried out over a decade in the Mediterranean regions. It focuses on three interrelated themes: the experiences of homecoming migrants who visit their country of origin for holidays; the inequalities surrounding the encounters between local people, tourists and migrants in borderlands; and how migration and tourism affect cultural heritage in European cities. The book shows how interconnected



mobilities play a crucial role in boosting the global dynamics of cultural, social, economic and political transformation in the Mediterranean.

Shipwreck in Haven -- Falling in love through a description -- The plummet of vitruvius -- Epilogue : stone angels.

Sommario/riassunto

This compelling selection of recent work by internationally celebrated poet Keith Waldrop presents three related poem sequences-"Shipwreck in Haven," "Falling in Love through a Description," and "The Plummet of Vitruvius"-in a virtuosic poetic triptych. In these quasi-abstract, experimental lines, collaged words torn from their contexts take on new meanings. Waldrop, a longtime admirer of such artists as the French poet Raymond Queneau and the American painter Robert Motherwell, imposes a tonal override on purloined materials, yet the originals continue to show through. These powerful poems, at once metaphysical and personal, reconcile Waldrop's romantic tendencies with formal experimentation, uniting poetry and philosophy and revealing him as a transcendentalist for the new millennium.
