input: Bartram returned to Philadelphia in January 1777 and assisted his brother John in all aspects of running Bartram's Garden. In the late 1780s, he completed the book for which he became most famous, Travels through North and South Carolina, Georgia, East and West Florida, the Cherokee Country, etc.. It was considered at the time one of the foremost books on American natural history. Many of Bartram's accounts of historical sites were the earliest records, including the Georgia mound site of Ocmulgee. In addition to its contributions to scientific knowledge, Travels is noted for its original descriptions of the American countryside. Bartram's writing influenced many of the Romantic writers of the day. William Wordsworth, Samuel Taylor Coleridge, and Francois-Rene de Chateaubriand are known to have read the book, and its influence can be seen in many of their works. Although Bartram has often been characterized as a recluse, all evidence shows that he remained active in commercial, scientific, and intellectual pursuits well into the nineteenth century. He tutored nieces and nephews, penned a number of essays, contributed to several works anonymously, and helped run the family horticultural business. In 1802, Bartram met the school teacher Alexander Wilson and began to teach him the rudiments of ornithology and natural history illustration. Wilson's American Ornithology includes many references to Bartram and the area around Bartram's Garden. Among Bartram's more significant later contributions were the illustrations for his friend Benjamin Smith Barton's explanation of the Linnaean system, Elements of Botany (1803-04). After the War of 1812, when many of his colleagues, contacts, and friends had died, Bartram settled into a long period of work, observation, and study at the family's garden in Kingsessing. He maintained a "Diary" that records bird migrations, plant life, and the weather. He refused a request to teach botany at the University of Pennsylvania, and in his sixties, declined an invitation from President Thomas Jefferson to accompany an expedition up the Red River in the Louisiana Territory, in 1806. He died at his home at the age of 84.

input: The group has publicized special events to choose the promotional and recording lineups for some of its singles. In 2009, the concept of senbatsu sosenkyo (Xuan Ba Zong Xuan Ju , "selection general election") was introduced, which allowed fans to vote their favorite members into the promotional line up or senbatsu (Xuan Ba , "selection") for one of their annual singles. Ballots are obtained by purchasing the group's latest "election single", or, alternatively, through the group's mobile app products and fan club subscriptions. Top vote getting members are heavily promoted, with the winner getting the centerpiece of the group's live performances of the single. The total pool of votes counted has exceeded three million votes for individual events since 2015. Fans have reportedly bought hundreds of copies of singles to vote for their favorite members. Another selection method, AKB48's rock-paper-scissors tournaments, was introduced in 2010 for the group's 19th single ("Chance no Junban") and has recurred as an annual event. Members of AKB48 and its sister groups compete in the knockout tournament to be part of the recording and promotional lineup for the group's next single, with participants wearing a variety of costumes. Starting with 2014, the tournament does not determine the promotional line up of a single anymore. Instead, the winner would debut as a soloist or, if she was already a soloist, would perform a solo concert. AKB48 has also used the general election scheme to determine set lists for an annual Request Hour (rikuesutoawa, rikuesuto awa) show. Other annual events include an AKB48 group only version of Kohaku Uta Gassen and the AKB group draft meeting (AKB48gurupu dorahutoHui Yi , AKB48 gurupu dorafuto kaigi), in which all teams from any of the sister groups chose new members from a pre-selected group of applicants.

input: In the 17th century a weakened Khmer state left the Mekong Delta poorly administered after repeated warfare with Siam. Concurrently Vietnamese refugees fleeing the Trinh-Nguyen War in Vietnam migrated into the area. In 1623 Cambodian king Chey Chettha II (1618-1628) officially sanctioned the Vietnamese immigrants to operate a custom house at Prey Nokor, then a small fishing village. The settlement steadily grew soon becoming a major regional port, attracting even more settlers. In 1698 the Nguyen Lords of Hue commissioned Nguyen Huu Canh, a Vietnamese noble to organize the territory along Vietnamese administrative lines, thus by de facto detaching it from the Kingdom of Cambodia and incorporating it into Vietnam. With the loss of the port of Prey Nokor, then renamed Sai Gon, Cambodia's control of the area grew increasingly tenuous while increasing waves of Vietnamese settlers to the Delta isolated the Khmer of the Mekong Delta from the Cambodian kingdom. By 1757 the Vietnamese had absorbed the provinces of Psar Dek (renamed Sa Dec in Vietnamese) on the Mekong itself, and Moat Chrouk (Vietnamized to Chau Doc) on the Bassac River. Minh Mang enacted assimilation policies upon the Khmer such as forcing them to adopt Sino-Vietnamese surnames, culture, and clothing. Minh Mang sinicized ethnic minorities including the Cambodians, in line with Confucianism as he diffused Vietnamese culture with China's Han civilization using the term Han people Han Ren for the Vietnamese. Minh Mang declared that "We must hope that their barbarian habits will be subconsciously dissipated, and that they will daily become more infected by Han [Sino-Vietnamese] customs." These policies were directed at the Khmer and hill tribes. On June 4, 1949 the French President Vincent Auriol signed the accord reincorporating Cochinchina to Vietnam. This was done without consulting the indigenous Khmer-Krom. The legal transfer of control cut Cambodia off from the sea via the Mekong River as the Delta administered by an independent Vietnam. Left within the borders of Vietnam were the communities of Khmer people, nowadays Khmer Krom.
