Background: Dafydd Rhys "Dave" Williams OC (born May 16, 1954) is a Canadian physician, public speaker and a retired CSA astronaut. Williams was a mission specialist on two space shuttle missions. His first spaceflight, STS-90 in 1998, was a 16-day mission aboard Space Shuttle Columbia dedicated to neuroscience research. His second flight, STS-118 in August 2007, was flown by Space Shuttle Endeavour to the International Space Station.
Context: In January 1995, Williams was selected to join the 1995 international class of NASA mission specialist astronaut candidates. He reported to the Johnson Space Center in March 1995 and completed training and evaluation in May 1996. On completing basic training, he was assigned to work technical issues for the payloads/habitability branch of the astronaut office.  From July 1998 to November 2002, Williams served as Director of the Space and Life Sciences directorate with responsibility for research in both physical and biomedical space sciences at the Johnson Space Center (JSC). With this appointment, he became the first non-American to hold a senior management position within NASA. Overall crew medical safety was one of his principal concerns, in addition to flight medical operations and JSC occupational and environmental health. His programs were directed toward protecting astronauts from the hazards of the space environment, including space radiation and microgravity, in addition to maintaining their medical, physical, and psychological well-being while aloft and on return to Earth. His other oversight responsibilities were in the fields of telemedicine, 3-D tissue culture/regeneration in microgravity, the curatorial management of extraterrestrial materials, and of qualifying humans for very long space journeys and ensuring their safe return to Earth.  Williams served as an aquanaut on the first NEEMO (NASA Extreme Environment Mission Operations) crew aboard the Aquarius underwater laboratory in October 2001. During this mission, he was thrilled to shake hands underwater with Canadian underwater explorer Joe MacInnis. Williams was originally scheduled to command NEEMO 7 in October 2004, but was replaced by back-up crewmember and fellow CSA astronaut Robert Thirsk due to Williams undergoing review of a temporary medical issue. In April 2006, Williams commanded the NEEMO 9 mission. During this eighteen-day mission, the six-person crew developed lunar surface exploration procedures and telemedical technology applications.

Problem: Background: The Turkana are a Nilotic people native to the Turkana District in northwest Kenya, a semi-arid climate region bordering Lake Turkana in the east, Pokot, Rendille and Samburu people to the south, Uganda to the west, and South Sudan and Ethiopia to the north. They refer to their land as Turkan. According to the 2009 Kenyan census, Turkana number 855,399, or 2.5% of the Kenyan population, making the Turkana the third largest Nilotic ethnic group in Kenya, after the Kalenjin and the Luo, slightly more numerous than the Maasai, and the tenth largest ethnicity in all of Kenya. Although this figure was initially controversial and rejected as too large by Planning Minister Wycliffe Oparanya, a court ruling (Feb 7, 2012) by Justice Mohammed Warsame (judge) stated that the Kenyan government accepts the 2009 census figures for Turkana.
Context: The Turkana entered Turkana basin from the north as one unit of the Ateker confederation. This cluster split as a result of internal differences, leading to the emergence of distinct independent groups. The Turkana people emerged as a victorious group in the subsequent conflict, which led to enmity between the Turkana and other Ateker cluster groups, who formed military alliances against the Turkana. The Turkana emerged victorious again by co-opting young people from conquered groups. The military power and wealth of the Turkana increased in what is now the northern plains of Turkana.  The establishment of the Turkana people developed as a distinct group which expanded southwards conquering ethnic nations south of its borders. The Turkana people easily conquered groups it came in contact with by employing superior tactics of war, better weapons and military organization. By the 1600s, the Turkana basin had been fully occupied by the Turkana and their allies.  There was a relative long period of peace among indigenous ethnic communities around Turkana until the onset of European colonization of Africa. Sporadic conflicts involved Turkana fights against Arab, Swahili and Abyssinian slave raiders and ivory traders. European colonization brought a new dimension to conflict with Turkana putting up a lasting resistance to a complex enemy, the British. The Turkana put up and maintained active resistance to British colonial advances leading to a passive presence of colonial administration. By the outbreak of World War I, few parts of Turkana had been put under colonial administration.  From World War I through to the end of World War II, Turkana actively participated in the wars as allies of Britain against invading Italy. Turkana was used as the launching pad for the war against invading Italian forces leading to the liberation of Abyssinia.  After World War II, the British led disarmament and pacification campaigns in Turkana, leading to massive disruptions and dispossession of Turkana pastoralists. The colonial administration practiced a policy of deliberate segregation of Turkana people by categorizing Turkana Province as a closed district. This led to marginalization and underdevelopment in the lead up to Kenya's independence.
