Hawaiis native minority is demanding a greater degree of sovereignty over its own affairs. But much of the archipelagos political establishment, which includes the White Americans who dominated until the second world war and people of Japanese, Chinese and Filipino origins, is opposed to the idea.
The islands were annexed by the US in 1898 and since then Hawaiis native peoples have fared worse than any of its other ethnic groups. They make up over 60 percent of the states homeless, suffer higher levels of unemployment and their life span is five years less than the average Hawaiians. They are the only major US native group without some degree of autonomy.
But a sovereignty advisory committee set up by Hawaiis first native governor, Joahn Waihee, has given the natives cause a major boost by recommending that the Hawaiian natives decide by themselves whether to reestablish a sovereign Hawaiian nation.
However, the Hawaiian natives are not united in their demands. Some just want greater autonomy within the state -- as enjoyed by many American Indian natives over matters such as education. This is a position supported by the Office of Hawaiian Affairs (OHA), a state agency set up in 1978 to represent the natives interests and which has now become the moderate face of the native sovereignty movement. More ambitious is the Ka Lahui group, which declared itself a new nation in 1987 and wants full, official independence from the US.
But if Hawaiian natives are given greater autonomy, it is far from clear how many people this will apply to. The state authorities only count as native those people with more than 50 percent Hawaiian blood.
Native demands are not just based on political grievances, though. They also want their claim on 660,000 hectares of Hawaiian crown land to be accepted. It is on this issue that native groups are facing most opposition from the state authorities. In 1933, the state government paid the OHA US 136 million in back rent on the crown land and many officials say that by accepting this payment the agency has given up its claims to legally own the land. The OHA has vigorously disputed this.

Cells cannot remain alive outside certain limits of temperature, and much narrower limits mark the boundaries of effective functioning. Enzyme systems of mammals and birds are most efficient only within a narrow range around 37 ℃; a departure of a few degrees from this value seriously impairs their functioning. Even though cells can survive wider fluctuations, the integrated actions of bodily systems are impaired. Other animals have a wider tolerance for changes of bodily temperature. For centuries it has been recognized that mammals and birds differ from other animals in the way they regulate body temperature. Ways of characterizing the difference have become more accurate and meaningful over time, but popular terminology still reflects the old division into "warm blooded" and "cold blooded" species; warm-blooded included mammals and birds whereas all other creatures were considered cold-blooded. As more species were studied, it became evident that this classification was inadequate. A fence lizard or a desert iguana —— each cold-blooded —— usually has a body temperature only a degree or two below that of humans and so is not cold. Therefore the next distinction was made between animals that maintain a constant body temperature, called homeotherms, and those whose body temperature varies with their environment, called poikilotherms. But this classification also proved inadequate, because among mammals there are many that vary their body temperatures during hibernation. Furthermore, many invertebrates that live in the depths of the ocean never experience a change in the chill of the deep water, and their body temperatures remain constant.

Sleep is part of a persons daily activity cycle. There are several different stages of sleep, and they too occur in cycles. If you are an average sleeper, your sleep cycle is as follows. When you first drift off into slumber, your eyes will roll about a bit, your temperature will drop slightly, your muscles will relax, and your breathing well slow and become quite regular. Your brain waves slow down a bit too, with the alpha rhythm of rather fast waves predominating for the first few minutes. This is called stage 1 sleep. For the next half hour or so, as you relax more and more, you will drift down through stage 2 and stage 3 sleep. The lower your stage of sleep, the slower your brain waves will be. Then about 40 to 60 minutes after you lose consciousness you will have reached the deepest sleep of all. Your brain waves will show the large slow waves that are known as the delta rhythm. This is stage 4 sleep.You do not remain at this deep fourth stage all night long, but instead about 80 minutes after you fall into slumber, your brain activity level will increase again slightly. The delta rhythm will disappear, to be replaced by the activity pattern of brain waves. Your eyes will begin to dart around under your closed eyelids as if you were looking at something occurring in front of you. This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep. It is during REM sleep period, your body will soon relax again, your breathing will grow slow and regular once more, and you will slip gently back from stage 1 to stage 4 sleep - only to rise once again to the surface of near consciousness some 80 minutes later.

睡眠是人每天日�；顒�(dòng)循環(huán)的一部分。人的睡眠分幾個(gè)階段，而這些階段也是循環(huán)發(fā)生的。如果你是一個(gè)正常的睡眠者，你的睡眠循環(huán)會(huì)這樣進(jìn)行。在你開(kāi)始昏昏入睡時(shí)，你的眼睛會(huì)滾動(dòng)幾下，體溫略有下降，肌肉放松，呼吸變得緩慢而有節(jié)奏。除了開(kāi)始幾分鐘 比較快的α節(jié)奏外，腦電波也稍有減緩。這被稱為第一階段睡眠。 在隨后約半小時(shí)內(nèi)，你進(jìn)一步放松，進(jìn)入第二和第三階段睡眠。睡眠越深入，腦電波就越緩慢。大約在開(kāi)始睡眠 后的 40 到 60 分鐘，你將進(jìn)入沉睡狀態(tài)。這時(shí)的腦電波表現(xiàn)為巨大的緩波，被稱為δ節(jié)奏。這就是第四階段睡眠。但你并不是整夜都保持這種沉睡狀態(tài)。入睡后約 80 分鐘左右，你的大腦運(yùn)動(dòng)水平會(huì)再度略有提高。δ節(jié)奏消失，并被腦電波的運(yùn)動(dòng)圖形取代。你的眼睛會(huì)在閉著的眼瞼下迅速轉(zhuǎn)動(dòng)，就好象你在看著眼前發(fā)生的什么事情。 這種迅速的眼球運(yùn)動(dòng)持續(xù)約 8～15 分鐘，這一階段睡眠被稱之為快速眼動(dòng)(REM)睡眠。在REM 睡眠階段，你的肢體會(huì)很快再度放松，呼吸也再次放慢并變得有節(jié)奏，你會(huì)輕松地從第一階段滑入第四階段睡眠一直到大約80 分鐘后重新接近清醒狀態(tài)。
