USS Thomas E. Fraser: USS "Thomas E. Fraser" (DD-736/DM-24) was a "Robert H. Smith"-class destroyer minelayer in the United States Navy.  She was named for Commander Thomas E. Fraser (1901–1942).

Webster/Sainte-Laguë method: The Webster/Sainte-Laguë method, often simply Webster method or Sainte-Laguë method (] ), is a highest quotient method for allocating seats in party-list proportional representation used in many voting systems.  It is named in Europe after the French mathematician André Sainte-Laguë and in United States after statesman and senator Daniel Webster.  The method is quite similar to the D'Hondt method, but uses different divisors.  In most cases the largest remainder method delivers almost identical results.  The D'Hondt method gives similar results too, but favors larger parties compared to the Webster/Sainte-Laguë method.  Often there is an electoral threshold, that is a minimum percentage of votes required to be allocated seats.

Krishna III: Krishna III whose Kannada name was Kannara (r. 939 – 967 C.E.) was the last great warrior and able monarch of the Rashtrakuta Dynasty of Manyakheta.  He was a shrewd administrator and skillful military campaigner.  He waged many wars to bring back the glory of the Rashtrakutas and played an important role in rebuilding the Rashtrakuta empire.  He patronised the famous Kannada poets Sri Ponna, who wrote "Shanti purana", Gajankusha, also known as Narayana, who wrote on erotics, and the Apabhramsha poet Pushpadanta who wrote "Mahapurana" and other works.  His queen was a Chedi princess and his daughter Bijjabbe was married to a Western Ganga prince.  During his rule he held titles such as "Akalavarsha", "Maharajadhiraja", "Parameshvara", "Paramamaheshvara", "Shri Prithvivallabha" etc.  At his peak, he ruled a vast empire stretching from the Narmada river in the north to the Kaveri river delta in the south.  A copper grant of 993 issued by the Shilahara king of Thana claims the Rashtrakuta control extended from the Himalayas in the north to Ceylon in the south and from the eastern sea to the western seas.  The grant states that when King Krishna III mobilised his armies, the kings of Chola, Bengal, Kannauj, Andhra and Pandya regions used to quiver.

The Fifties (book): The Fifties (ISBN  , 1993) is a historical account by David Halberstam about the decade of the 1950s in the United States.  Rather than using a straightforward linear narrative, Halberstam separately tracks many of the notable trends and figures of the post-World War II era, starting with Harry Truman's stunning Presidential victory in 1948 against Thomas E. Dewey.  Halberstam chronicles many political and cultural trends during the decade, including the beginnings of the Civil Rights Movement and the Cold War, the creation of rock and roll via the rise of Elvis Presley, the introduction of fast food and mass marketing via the rise of McDonald's, the Holiday Inn hotel chain, the transformation of General Motors into the center of new car culture through the work of designer Harley Earl, the beginnings of the sexual revolution with the creation of the birth control pill, and the beginnings of the American counterculture through the emergence of actors Marlon Brando and James Dean and Beat Generation writers Jack Kerouac and Allen Ginsberg.  The book ends with an account of the first televised debate between Richard Nixon and John Kennedy, serving as a prelude to the 1960s.

Conscription in the United States: Conscription in the United States, commonly known as the draft, has been employed by the federal government of the United States in four conflicts: the American Civil War, World War I, World War II, and the Cold War (including both the Korean and Vietnam Wars).  The third incarnation of the draft came into being in 1940 through the Selective Training and Service Act.  It was the country's first peacetime draft.  From 1940 until 1973, during both peacetime and periods of conflict, men were drafted to fill vacancies in the United States Armed Forces that could not be filled through voluntary means.  The draft was ended when the United States Armed Forces moved to an all-volunteer military force.  However, the Selective Service System remains in place as a contingency plan; all male civilians between the ages of 18 and 25 are required to register so that a draft can be readily resumed if needed.

Rural Free Delivery: Rural Free Delivery (RFD) is a service which began in the United States in the late 19th century, to deliver mail directly to rural farm families.  Prior to RFD, individuals living in more remote homesteads had to pick up mail themselves at sometimes distant post offices or pay private carriers for delivery.  RFD became a political football, with politicians promising it to voters and using it themselves to reach voters.  The proposal to offer free rural delivery was not universally embraced.  Private carriers and local shopkeepers feared a loss of business.  The United States Post Office Department began experiments with Rural Free Delivery as early as 1890.  However, it was not until 1893, when Georgia Congressman Thomas E. Watson pushed through legislation, that the practice was mandated.  However, universal implementation was slow; RFD was not adopted generally in the United States Post Office until 1902.  The rural delivery service uses a network of rural routes traveled by carriers to deliver and pick up mail to and from roadside mailboxes.
