The Man Booker International Prize is an international hosted in the United Kingdom.  The introduction of the International Prize to complement the Man Booker Prize was announced in June 2004.  Sponsored by the Man Group, from 2005 until 2015 the award was given every two years to a living author of any nationality for a body of work published in English or generally available in English translation.  It rewarded one author's "continued creativity, development and overall contribution to fiction on the world stage", and was a recognition of the writer's body of work rather than any one title.  The judges for the year compiled their own lists of authors, and submissions were not invited. Lafayette Park is a historic urban renewal district east of Downtown Detroit and contains the largest collection of residential buildings designed by Ludwig Mies van der Rohe.  The northern section planned and partially built by Mies is listed in the National Register of Historic Places.  In 2015 it was designated a National Historic Landmark District.  Lafayette Park is located on the city's lower east side directly south of the Eastern Market Historic District.  In general, the neighborhood, including portions developed by other architects, has been regarded as an incubator of progressive architecture and one of the few historically stable urban renewal zones in the United States. Lafayette in the Somewhat United States is a 2015 non-fiction work written by Sarah Vowell. An accidental American is a citizen of a country other than the United States who may also be considered a U.S. citizen under U.S. nationality law but is not aware of having U.S. status, or has only become aware of it recently during adulthood.  Accidental Americans' U.S. citizenship arises due to their parents' ties to the United States rather than their own choices: they may be born in their own country but to one U.S. citizen parent who emigrated from the United States, or they may be born in the U.S. to parents residing in the country temporarily for work or study and then return to their own country in their early childhood, with few if any memories of the United States.  The term may also sometimes be applied to people who definitely are not U.S. citizens but have some other sort of connection with the country, for example green card holders who moved back to their country of origin and let their green cards expire without formally cancelling their U.S. immigration status, or non-U.S. citizens married to Americans abroad.  Such tenuous connections to the United States began to become a more salient issue in the late 2000s due to Internal Revenue Service crackdowns which were ostensibly aimed at tax evaders hiding assets in secrecy jurisdictions but ended up having much broader effects on people with U.S. citizenship who resided in other countries, as well as their families. The Carneal House is a historic residence located at 405 East Second Street in Covington, Kentucky, United States.  Commonly believed to be Covington's oldest surviving structure, the home was begun in the year 1815 by Thomas D. Carneal, one of the founders of the city of Covington.  Carneal House is a two-story brick home with arched windows, built in an Italianate-Federalist style and somewhat influenced by late-Renaissance architect Andrea Palladio.  Among noted visitors to the home was Revolutionary War hero the Marquis de Lafayette, who paid a call during his final American tour in 1824–1825.  House was built for Aaron Gano in 1815 and sold to William Southgate in 1825.  Lafayette's visit to the Southgates has been misunderstood, since the visit took place at Mrs. Adelizza Keene Southgate's home in Lexington, where they were visiting.
