Osiris, and to justify himself before being permitted to enter the realms of bliss. This he imagined he could in great part accomplish by the recitation of various magical formula and spells, which would ward off the evil influences opposed to him. To this end every important Egyptian of means had buried with him a papyrus of the Book of the Dead, containing at least all the chapters necessary for encountering the formidable adversaries at the gates of Amenti, the Egyptian Hades. These chapters would assist him in making replies during his ceremony of justification. First among these spells were the \The Egyptians believed that to discover the \him. Sympathetic magic was in vogue in Egyptian burial practice, which explains the presence, in tombs of people of means, of paintings of tables laden with food and drink, with inscriptions attached conveying the idea of boundless liberality. Inscriptions like the following are extremely common—\double or soul] of so-and-so, 5,000 loaves of bread, 500 geese, and 5,000 jugs of beer.\cost the generous donors little, as they merely had the objects named painted upon the wall of the tomb, imagining that their ka or astral counterpart would be eatable and drinkable by the deceased. This of course is merely an extension of the Neolithic conception that articles buried with a man had their astral counterparts and would be of use to him in another world. Pictorial representation played a considerable part in the magical ritual of the Book of the Dead. One of the pleasures of the dead was to sail over Heaven in the boat of Ra, and to secure this for the deceased one must paint certain pictures and mutter over them words of power. Regarding this belief, E. A. Wallis Budge states in his book Egyptian Magic (1889): \piece of clean papyrus a boat is to be drawn with ink made of green abut mixed with anti water, and in it are to be figures of Isis, Thoth, Shu, and Khepera, and the deceased; when this had been done the papyrus must be fastened to the breast of the deceased, care being taken that it does not actually touch his body. Then shall his spirit enter into the boat of Ra each day, and the god Thoth shall take heed to him, and he shall sail about with him into any place that he wisheth. Elsewhere it is ordered that the boat of Ra be painted 'in a pure place,' and in the bows is to be painted a figure of the deceased; but Ra was supposed to travel in one boat (called Atet) until noon, and another (called Sektet) until sunset, and provision had to be made for the deceased in both boats. How was this to be done? On one side of the picture of the boat a figure of the morning boat of Ra was to be drawn, and on the other a figure of the afternoon boat; thus the one picture was capable of becoming two boats. And, provided the proper offerings were made for the deceased on the birthday of Osiris, his soul would live for ever, and he would not die a second time. According to the rubric to the chapter in which these directions are given, the text of it is as old, at least, as the time of Hesept, the fifth king of the 1st. dynasty, who reigned about 4350 B.C. , and the custom of painting the boat upon papyrus is probably contemporaneous.%until after death. They were \thing of abomination for every man to know it. Hide it, therefore, the Book of the Lady of the Hidden Temple is its name.\Ra or Horus from trouble, or was of benefit to him, thus was concluded to be equally efficacious in the case of the deceased. Many spells were included in the Book of the Dead for the purpose of preserving the mummy against molding and for assisting the owner of the papyrus to become as a god and to be able to transform himself into any shape he desired. Painted offerings were also provided so the deceased would be able to give gifts to the gods. It is apparent that the Book of the Dead was undoubtedly magical in character, consisting as it did of a series of spells or words of power, which enabled the speaker to have perfect control over all the powers of Amenti. The only moment in which the dead man is not master of his fate is when his heart is weighed by Thoth before Osiris. If it does not conform to the standard required for justification, he is cast out; except for this, an absolute knowledge of the Book of the Dead safeguarded the deceased in every way from the danger of damnation. A number of the chapters consist of prayers and hymns to the gods, but the directions as to the magical uses of the book are equally numerous; the concept of supplication is mingled with the idea of circumvention by sorcery in the most extraordinary manner.There is a lso evidence of a higher proportion of perinatal complications (complications arising around the time of giving birth) among children with autistic symptoms. These complications include maternal bleeding after the first trimester and meconium in the amniotic fluid. (Meconium is a substance that accumulates in the bowel of the developing fetus and is discharged shortly after birth.) Some evidence suggests that the use of medications during pregnancy may be related to the development of autistic symptoms. As newborns, children with autistic behaviors show a higher rate of respiratory illness and anemia than healthy children. ALLERGIES, INFECTIONS, AND IMMUNIZATIONS. Some professionals believe that autistic disorders may be caused by allergies to particular fungi, viral infections, and various foods. No controlled studies have supported these beliefs, but some parents and professionals report improvement when allergens and/or certain foods are eliminated from the diet. Viral infections of the mother, such as rubella, or of the young child, such as encephalitis, mumps, and measles, occasionally appear to cause autistic disorders. The issue is not how hazardous boxing is but whether the hazards are acceptable. The term \cluster of conditions appearing early in childhood. All involve severe impairments in social interaction, communication, imaginative abilities, and rigid, repetitive behaviors. To be considered an autistic disorder, some of these impairments must be manifest before the age of three. The reference book used by mental health professionals to diagnose mental disorders is the Diagnostic and Statistical Manual of Mental Disorders , also known as the DSM. The 2000 edition of this reference book (the Fourth Edition Text Revision known as DSM-IV-TR ) places autism in a category called pervasive developmental disorders . All of these disorders are characterized by ongoing problems with mutual social interaction and communication, or the presence of strange, repetitive behaviors,interests, and activities. People diagnosed with these disorders are affected in many ways for their entire lives. Description Each child diagnosed with an autistic disorder differs from every other, and so general descriptions of autistic behavior and characteristics do not apply equally to every child. Still, the common impairments in social interaction, communication and imagination, and rigid, repetitive behaviors make it possible to recognize children with these disorders, as they differ markedly from healthy children in many ways. Many parents of autistic children sense that something is not quite right even when their children are infants. The infants may have feeding problems, dislike being changed or bathed, or fuss over any change in routine. They may hold their bodies rigid, making it difficult for parents to cuddle them. Or, they may fail to anticipate being lifted, lying passively while the parent reaches for them, rather than holding their arms up in return. Most parents of autistic children become aware of the strangeness of these and other behaviors only gradually. Imagine 第25页

too the state of even the winner's hands, protected only by having been soaked in brine. With their combination of boxing and wrestling moves, early contests were literally ‘no holds barred’; grappling, punching, tripping, and throwing all being used to floor an opponent. The widely-adopted Broughton's Rules of 1743 eradicated some of the barbarism by outlawing the hitting of a man when he was down, and the seizing of hair or the body below the waist, but they still permitted butting. Yet it was not the brutality of the prize-ring which brought its demise, but the corruption with which it became associated. The revival of the sport as boxing in late Victorian Britain saw several changes designed to render it more civilized. Although some of the old practices continued for a while — even the famous Queensbury Rules initially allowed endurance contests — by the turn of the century the general picture was one of boxing in gloves, limited-time rounds, points decisions after a fixed number of rounds had elapsed, and weight divisions, though the latter have accentuated problems of dehydration as fighters struggle to ‘make the weight’. For much of the twentieth century the history of boxing has been one of crumbling resistance to changes intended to protect further the brains and bodies of participants. Between 1984 and 1993 eight boxers had died soon after fights in the UK; bantamweight Bradley Stone was added to the list in 1994. Following a report from a medical working party, which included neurosurgeons, the British Boxing Board of Control subsequently introduced mandatory annual magnetic resonance imaging scans for all boxers to replace the less sophisticated computerized tomography which had been compulsory only for those fighting eight rounds or more. Additionally, any boxer knocked out must wait 45 days (previously 28) before he again enters the ring competitively, and he must also have a hospital check. Ringside doctors may advise referees on a fighter's condition between rounds and may recommend that the contest be stopped. Doctors also examine each boxer at the conclusion of fights and paramedic teams must be on hand at all boxing bills. The medical profession in several countries has increasingly adopted an anti-boxing stance, citing irreversible brain damage as its major objection to the sport. This is a key point for, in absolute terms of deaths and serious injuries, other sports such as horseracing, mountaineering, However, headguards, whilst absorbing energy from punches, present an even larger target to be hit and thus the number of blows striking home may well increase. Indeed, studies have shown that non-boxing sportsmen outperform even amateur fighters in neurological tests and, notwithstanding the safety precautions, three amateur fighters have suffered serious brain injury in British rings since 1988. For centuries boxing has been the epitome of overt masculinity, a demonstration of manliness and its embodying characteristics of courage, toleration of pain, and self-discipline. Women were merely ornaments displaying the round cards. This continues, but women have successfully demanded equal rights in the ring. In Britain, girls from the age of 10 are now allowed to spar in amateur boxing gyms, and recently professionalism, too, has been recognized for women — significantly later than its acceptance in the US where fights for women have appeared on the undercard of world championship events. The moral dilemma of boxing is that it provides an honest opportunity to escape poverty, but it also means for some a legal beating and for all the threat of permanent damage. Hitting below the belt is outlawed to protect the genitals, but surely the brain deserves even more protection, by reducing the concussive power of the boxing glove, developing safer headgear, excluding the head as a target — or by banning the sport altogether. Impairments in social interaction are usually among the earliest symptoms to develop. The most common social impairment is a kind of indifference to other people, or aloofness, even towards parents and close care-givers. The baby may fail to respond to his or her name being called and may show very little facial expression unless extremely angry, upset, or happy. Babies with autism may resist being touched, and appear to be lost in their own world, far from human interaction. Between seven and 10 months of age, most infants often resist being separated from a parent or well-known caregiver, but these infants may show no disturbance when picked up by a stranger. Other children with autism may be very passive, although less resistant to efforts by others to interact. However, they do not initiate social interaction themselves. Still others may attempt to engage with adults and peers, but in ways that strike others as inappropriate, or odd. In adolescence and adulthood, some of the higher-functioning individuals with autistic disorders may appear overly formal and polite. They may react with little spontaneity, as if social interaction doesn't come naturally or easily to them, and so they are trying to follow a pre-determined set of rules.
