The Florida Architecture of F. Burrall Hoffman Jr., 1882-1980

Everyone interested in Florida’s architectural history should know of Francis Burrall Hoffman Jr. and his connection to Miami’s great villa Vizcaya. Few realize he had a distinguished Florida career spanning over sixty years and designed buildings in several sections of the state. In fact, when the United States entered World War I in 1917, the thirty-five-year-old Hoffman may have been, in terms of cost of commissions, Florida’s most successful domestic architect. In only eight short years of private practice, Hoffman had designed Vizcaya, the Biscayne Bay mansion, for industrialist James Deering, large oceanfront residences in Palm Beach for Mrs. Frederick Guest and her brother Henry Carnegie Phipps (their father had been Andrew Carnegie’s partner), and probably had received the commission for the elaborate music room of Pittsburgh industrialist Joseph Riter, which he completed at the war’s end. Moreover, Hoffman returned to Florida to design several houses and Our Lady of Mercy Chapel on Boca Grande; a half century later he began to winter on Jupiter Island where he completed his last major commissions

Joseph Urban\u27s Palm Beach Architecture

When Paris Singer established the Everglades Club, he changed forever the nature of Palm Beach as a winter resort. Until 1918 social life centered on the Flagler hotels and the Beach Club, Colonel Edward Bradley’s gambling casino. In the period after World War I, when growing wealth allowed America’s middle class to plan winter vacations, society found its exclusiveness threatened. Almost anyone who could afford it could register at the Royal Poinciana, the Breakers, or the Palm Beach Hotel. The Everglades Club, with its expensive restricted membership, allowed for a new definition of society in the winter resort

High resolution observation of microwave-optical double resonance in NO2

A previously reported microwave-optical double resonance observed in the fluorescence of NO2 excited by the 4880 \uc5 argon ion laser has been observed through a high resolution spectrograph. The common level in the double resonance is the 524 rotational level of a vibrational state of B 2 symmetry of the 2 B 2 electronic state of NO2. The optical transition exciting this level originates from the 431 level of the ground vibrational state of the 2 A 1ground electronic state of NO2. The most likely explanation of the double resonance is that the microwave transition is to the 523 level of another vibrational state of the 2 B 2 electronic state with A 1 vibrational symmetry. This level structure could be produced by an inversion splitting if the molecule had unequal N\u2013O bond lengths in its equilibrium geometry or by an accidental near coincidence between vibrational levels of a symmetrical molecule.Peer reviewed: YesNRC publication: Ye

Indirect effects of invasive rat removal result in recovery of island rocky intertidal community structure.

Eleven years after invasive Norway rats (Rattus norvegicus) were eradicated from Hawadax Island, in the Aleutian Islands, Alaska, the predicted three-level trophic cascade in the rocky intertidal, with native shorebirds as the apex predator, returned, leading to a community resembling those on rat-free islands with significant decreases in invertebrate species abundances and increases in fleshy algal cover. Rats had indirectly structured the intertidal community via their role as the apex predator in a four-level trophic cascade. Our results are an excellent example of an achievable and relatively short-term community-level recovery following removal of invasive animals. These conservation successes are especially important for islands as their disproportionately high levels of native biodiversity are excessively threatened by invasive mammals
