Background: Martina Hingis (born 30 September 1980) is a Swiss former professional tennis player who spent a total of 209 weeks as the singles world No. 1 and 90 weeks as doubles world No. 1, holding both No. 1 rankings simultaneously for 29 weeks. She won five Grand Slam singles titles, thirteen Grand Slam women's doubles titles, winning a calendar-year doubles Grand Slam in 1998, and seven Grand Slam mixed doubles titles; for a combined total of twenty-five major titles. In addition, she won the season-ending WTA Finals two times in singles and three times in doubles, and an Olympic silver medal.
Context: In 2001, Switzerland, with Hingis and Roger Federer on its team, won the Hopman Cup. Hingis didn't drop a set in any of her singles matches during the event, defeating Tamarine Tanasugarn, Nicole Pratt, Amanda Coetzer, and Monica Seles. Federer was later quoted as saying: "I learned a lot from her, especially the two years I was here - once as a hitting partner and once as a partner with Martina. Definitely she helped me to become the player I am today."  Hingis reached her fifth consecutive Australian Open final in 2001, defeating both of the Williams sisters en route, before losing to Jennifer Capriati. She briefly ended her coaching relationship with her mother Melanie early in the year but had a change of heart two months later just before the French Open. 2001 was her least successful year in several seasons, with only three tournament victories in total. She lost her No. 1 ranking for the last time (to Jennifer Capriati) on 14 October 2001. In that same month, Hingis underwent surgery on her right ankle.  Coming back from injury, Hingis won the Australian Open doubles final at the start of 2002 (again teaming with Anna Kournikova) and reached a sixth straight Australian Open final in singles, again facing Capriati. Hingis led by a set and 4-0 and had four match points but lost in three sets. In May 2002, she needed another ankle ligament operation, this time on her left ankle. After that, she continued to struggle with injuries and was not able to recapture her best form.  In February 2003, at the age of 22, Hingis announced her retirement from tennis, due to her injuries and being in pain. "I want to play tennis only for fun and concentrate more on horse riding and finish my studies." In several interviews, she has indicated she wishes to return to her home country and coach full-time.  During this segment of her tennis career, Hingis won 40 singles titles and 36 doubles events. She held the World No. 1 singles ranking for a total of 209 weeks (fifth most following Steffi Graf, Martina Navratilova (after whom she was named), Chris Evert, and Serena Williams). In 2005, Tennis magazine put her in 22nd place in its list of 40 Greatest Players of the TENNIS era.

Background: Ancient Hawai`i is the period of Hawaiian human history preceding the unification in 1810 of the Kingdom of Hawai`i by Kamehameha the Great. Researchers had based their estimates of first settlement by Polynesian long-distance navigators from French Polynesia, Tahiti, the Tuamotus and the Samoan Islands sporadically between 300 and 800. In 2010, a study was published based on radiocarbon dating of more reliable samples and it suggests that the islands were settled much later, within a short timeframe, in c. 1219 - 1266. The islands in Eastern Polynesia have been characterized by the continuities among their cultures, and the short migration period would be an explanation of this result.
Context: The colonists brought along with them clothing, plants (called "canoe plants") and livestock and established settlements along the coasts and larger valleys. Upon their arrival, the settlers grew kalo (taro), mai`a (banana), niu (coconut), ulu (breadfruit), and raised pua`a (pork), moa (chicken), and `ilio (poi dog), although these meats were eaten less often than fruits, vegetables, and seafood. Popular condiments included pa'akai (salt), ground kukui nut, limu (seaweed), and ko (sugarcane) which was used as both a sweet and a medicine. In addition to the foods they brought, the settlers also acquired `uala (sweet potato), which has yet to be adequately explained, as the plant originates in South America. A few researchers have argued that the presence of the sweet potato in the ancient Hawaiian diet is evidence of pre-Columbian trans-oceanic contact with the Americas.  The Pacific rat accompanied humans on their journey to Hawai`i. David Burney argues that humans, along with the vertebrate animals they brought with them (pigs, dogs, chickens and rats), caused many native species of birds, plants and large land snails to become extinct in the process of colonization.  Estuaries and streams were adapted into fishponds by early Polynesian settlers, as early as 1500 or more years ago. Packed earth and cut stone were used to create habitat, making ancient Hawaiian aquaculture among the most advanced of the original peoples of the Pacific. A notable example is the Menehune Fishpond dating from at least 1,000 years ago, at Alekoko. At the time of Captain James Cook's arrival, there were at least 360 fishponds producing 2,000,000 pounds (900,000 kg) of fish per year. Over the course of the last millennium, Hawaiians undertook "large-scale canal-fed pond field irrigation" projects for kalo (taro) cultivation.  As soon as they arrived, the new settlers built hale (homes) and heiau (temples). Archaeologists currently believe that the first settlements were on the southern end of the Big Island of Hawai`i and that they quickly extended northwards, along the seacoasts and the easily accessible river valleys. As the population increased, settlements were made further inland. At this time, with the islands being so small, the population was very dense. Before European contact, the population had reached somewhere in the range of 200,000 to 1,000,000 people. After contact with the Europeans, however, the population steeply dropped due to various diseases including smallpox.
