单选题In November 1970 Yukio Mishima, together with some of his fanatical followers from the ultra nationalistic Shield Society which he had founded in 1966, broke into the headquarters of Japan's Eastern Defense Forces armed with swords and daggers, overpowered some aides, tied up the commanding general, and demanded that the troops be assembled to hear a speech. Mishima addressed the troops for ten minutes, inciting them to rebel against the constitutional government imposed by the United States that had, in his words, "turned Japan spineless. " Receiving only ridicule in response, he returned to the general's office and there, before the general's unbelieving eyes, proceeded to kill himself in strict accordance with the traditional samurai ritual of seppuku. After Mishima had driven a dagger deep into left abdomen, one of his aides severed his head with a sword. The aide likewise killed himself and was beheaded; the others surrendered. In 1936 there had been a similar revolt and, though equally unsuccessful, it had foreshadowed the repressive regime of General Tojo that was to stage the attack on Pearl Harbor in 1941. That earlier revolt is the one referred to in Patriotism, one of Mishima's most powerful stories. Here life and fiction become joined. The act of seppuku was for Mishima a fulfillment, "the ultimate dream of my life. " Born of an ancient samurai family, he longed to die a hero's death in accordance with the ancient samurai code; but his weak body kept him from service in the war, and he had to compensate through body building (he became expert at karate and kendo) and, most important, through the discipline of writing. In his short lifetime he turned out twenty novels, thirty plays, many essays, and more than eighty stories; he also produced, directed, and acted in movies, and even sang on stage. His first book of stories, A Forest in Flower, appeared in 1943, but it was Confession of a Mask (1948), dealing with the meditations of a young man of homosexual leanings in a repressive society, that brought him fame. Mishima has been called "Japan's Hemingway", while others have compared him to "aesthetic" writers like Walter Peter and Oscar Wilde.

单选题For decades, researchers have grappled with the problem of creating a machine that can tell, definitively, whether a person is lying. Until recently, their work has been far from successful. The past generation of lie-detection technologies has been put under scientific scrutiny and found wanting. But science, ever resourceful, is coming up with new ideas. The problem with past lie detectors is that it relies on second-hand signs of lying, such as a person's breathing rate, pulse, blood pressure which a good actor can suppress. Furthermore, someone who is telling the truth might exhibit just these signals, because the very act of being questioned by the authorities is stressful. Instead, current research is looking directly at the source of lies, the brain itself. Daniel Langleben uses a brain-scanning technique called functional magnetic-resonance imaging to probe his subjects' honesty. The lie which those subjects are asked to tell is a small one: they have to persuade Dr. Langleben that they are holding a particular playing card when often they are actually holding a different one. Each successful deception earns a subject $20. The researchers have not had to hand out much cash, though. The brains of lying subjects light up in particular places in ways that they do not in the honest. Another brain-probing lie-detection technique, based on electroencephalography (EEG), has actually made it out of the laboratory and into the courtroom. Lawrence Farwell calls it MERMER (memory and encoding related multifaceted electroencephalographic response). MERMER works by hooking someone up to an EEG machine and asking him about specific details of, for example, a crime scene. Lack of a brainwave called P300 denotes lack of familiarity with the details in question, suggesting any denial should he taken at face value. The technique has already stood up to legal scrutiny twice. It will soon be used again, in the appeal by Jimmy Slaughter against his conviction for murdering his ex-girlfriend, Melody Wuertz. MERMER suggests that Mr. Slaughter had no recollection of important facts about the murder, such as which rooms the victim' body was located in. Although not yet foolproof, these methods do offer possible alternatives to the antiquated techniques of the polygraph. The truth is out there. It is just a question of finding it.
