<P0-S0> The Boy Who Reversed Himself (1986) is a science fiction novel by William Sleator. <P0-S1> The novel deals with an exploration into other dimensions, and provides a journey into the world beyond our own. <SEP> <P1-S0> the rohingya people have consistently faced human rights abuses by the burmese regime that has refused to acknowledge them as burmese citizens (despite some of them having lived in burma for over three generations)—the rohingya have been denied burmese citizenship since the enactment of a 1982 citizenship law. <P1-S1> the law created three categories of citizenship: citizenship, associate citizenship, and naturalised citizenship. <P1-S2> citizenship is given to those who belong to one of the national races such as kachin, kayah (karenni), karen, chin, burman, mon, rakhine, shan, kaman, or zerbadee. <P1-S3> associate citizenship is given to those who cannot prove their ancestors settled in myanmar before 1823, but can prove they have one grandparent, or pre-1823 ancestor, who was a citizen of another country, as well as people who applied for citizenship in 1948 and qualified then by those laws. <P1-S4> naturalized citizenship is only given to those who have at least one parent with one of these types of burmese citizenship or can provide "conclusive evidence" that their parents entered and resided in burma prior to independence in 1948. the burmese regime has attempted to forcibly expel rohingya and bring in non-rohingyas to replace them—this policy has resulted in the expulsion of approximately half of the 800,000 rohingya from burma, while the rohingya people have been described as "among the world's least wanted" and "one of the world's most persecuted minorities." <P1-S5> but the origin of ‘most persecuted minority’ statement is unclear. <SEP> <P2-S0> ``an occurrence at owl creek bridge '', a short story by american author ambrose bierce, is`` one of the most famous and frequently anthologized stories in american literature''. <P2-S1> originally published by the san francisco examiner on july 13, 1890, it was first collected in bierce's 1891 book tales of soldiers and civilians. <P2-S2> the story is set during the american civil war, in which bierce himself was a soldier. <SEP> <P3-S0> Rank War Years Deaths Deaths per day U.S. population in first year of war Deaths per population American Civil War 1861 -- 65 750,000 avg. <P3-S1> (U.S. / Confederate) 520 31,443,000 2.385% (1860) World War II 1941 -- 45 405,399 297 133,402,000 0.307% (1940) World War I 1917 -- 18 116,516 279 103,268,000 0.110% (1920) Vietnam War 1961 -- 75 58,209 11 179,323,175 0.032% (1970) 5 Korean War 1950 -- 53 54,246 45 151,325,000 0.036% (1950) 6 American Revolutionary War 1775 -- 83 25,000 11 2,500,000 1.00% (1780) 7 War of 1812 1812 -- 15 15,000 15 8,000,000 0.207% (1810) 8 Mexican -- American War 1846 -- 48 13,283 29 21,406,000 0.057% (1850) 9 Iraq War 2003 -- 2011 4,497 294,043,000 0.002% (2010) 10 Philippine -- American War 1899 -- 1902 4,196 3.8 72,129,001 0.006% (1900) 11 Spanish -- American War 1898 2,246 8.9 62,022,250 (1890) 12 War in Afghanistan 2001 - present 2,216 0.36 294,043,000 (2010) <SEP> <P4-S0> William Warner Sleator III (February 13, 1945 – August 3, 2011), known as William Sleator, was an American science fiction author who wrote primarily young adult novels but also wrote for younger readers. <P4-S1> His books typically deal with adolescents coming across a peculiar phenomenon related to an element of theoretical science, then trying to deal with the situation. <P4-S2> The theme of family relationships, especially between siblings, is frequently intertwined with the science fiction plotline.
