Passage 72(9/22) cD8Ea(
SinceWould War II considerable advances have been made in the area of health-careservices. These include better access to health care (particularly for the poorand minorities), improvements in physical plants, and increased numbers ofphysicians and other health personnel. All have played a part in the recentimprovement in life expectancy. But there is mounting criticism of the largeremaining gaps in access, unbridled cost inflation, the further fragmentationof service, excessive indulgence in wasteful high-technology “gadgeteering,”and a breakdown in doctor-patient relationships. In recent years, proposed panaceas and new programs,small and large, have proliferated at a feverish pace and disappointmentsmultiply at almost the same rate. This has led to an increasedpessimism—“everything has been tried and nothing works”—which sometimes borderson cynicism or even nihilism. Um'Ro 4
Itis true that the automatic “pass through” of rapidly spiraling costs togovernment and insurance carriers, which was set in a publicized environment of“the richest nation in the world,” produced for a time a sense of unlimitedresources and allowed to develop a mood whereby every practitioner andinstitution could “do his own thing” without undue concern for the “MedicalCommons.” The practice of full-cost reimbursement encouraged capital investmentand now the industry is overcapitalized. Many cities have hundreds of excesshospital beds; hospitals have proliferated a superabundance of high-technologyequipment; and structural ostentation and luxury were the order of the day. Inany given day, one-fourth of all community beds are vacant; expensive equipmentis underused or, worse, used unnecessarily. Capital investment brings rapidlyrising operating costs. Y"oDFo,
Yet,in part, this pessimism derives from expecting too much of health care. It mustbe realized that care is, for most people, a painful experience, oftenaccompanied by fear and unwelcome results. Although there is vast room forimprovement, health care will always retain some unpleasantness andfrustration. Moreover, the capacities of medical science are limited. HumptyDumpty cannot always be put back together again. Too many physicians arereluctant to admit their limitations to patients; too many patients andfamilies are unwilling to accept such realities. Nor is it true that everythinghas been tried and nothing works, as shown by the prepaid group practice plansof the Kaiser Foundation and at Puget Sound. In the main, however, suchundertakings have been drowned by a veritable flood of public and privatemoneys which have supported and encouraged the continuation of conventionalpractices and subsidized their shortcomings on a massive, almost unrestricted scale.Except for the most idealistic and dedicated, there were no incentives to seekchange or to practice self-restraint or frugality. In this atmosphere, it isnot fair to condemn as failures all attempted experiments; it may be moreaccurate to say many never had a fair trial. )-#i8?y3C

Passage 71(8/22) s@/B*r9
Behavioris one of two general responses available to endothermic (warm-blooded) speciesfor the regulation of body temperature, the other being innate (reflexive)mechanisms of heat production and heat loss. Human beings rely primarily on thefirst to provide a hospitable thermal microclimate for themselves, in which thetransfer of heat between the body and the environment is accomplished withminimal involvement of innate mechanisms of heat production and loss.Thermoregulatory behavior anticipates hyperthermia, and the organism adjustsits behavior to avoid becoming hyperthermic: it removes layers of clothing, itgoes for a cool swim, etc. The organism can also respond to changes in thetemperature of the body core, as is the case during exercise; but suchresponses result from the direct stimulation of thermoreceptors distributedwidely within the central nervous system, and the ability of these mechanismsto help the organism adjust to gross changes in its environment is limited. LZgwIMd
Untilrecently it was assumed that organisms respond to microwave radiation in thesame way that they respond to temperature changes caused by other forms ofradiation. After all, the argument runs, microwaves are radiation and heat bodytissues. This theory ignores the fact that the stimulus to a behavioralresponse is normally a temperature change that occurs at the surface of theorganism. The thermoreceptors that prompt behavioral changes are located withinthe first millimeter of the skin’s surface, but the energy of a microwave fieldmay be selectively deposited in deep tissues, effectively bypassing thesethermoreceptors, particularly if the field is at near-resonant frequencies. Theresulting temperature profile may well be a kind of reverse thermal gradient inwhich the deep tissues are warmed more than those of the surface. Since theheat is not conducted outward to the surface to stimulate the appropriatereceptors, the organism does not “appreciate” this stimulation in the same waythat it “appreciates” heating and cooling of the skin. In theory, the internalorgans of a human being or an animal could be quite literally cooked well-donebefore the animal even realizes that the balance of its thermomicroclimate hasbeen disturbed. [Od>NO,n+]
Untila few years ago, microwave irradiations at equivalent plane-wave powerdensities of about 100 mW/cm2 were considered unequivocally toproduce “thermal” effects; irradiations within the range of 10 to 100 mW/cm2might or might not produce “thermal” effects; while effects observed at powerdensities below 10 mW/cm2 were assumed to be “nonthermal” in nature.Experiments have shown this to be an oversimplification, and a recent reportsuggests that fields as weak as 1 mW/cm2 can be thermogenic. Whenthe heat generated in the tissues by an imposed radio frequency (plus the heatgenerated by metabolism) exceeds the heat-loss capabilities of the organism,the thermoregulatory system has been compromised. Yet surprisingly, not longago, an increase in the internal body temperature was regarded merely as“evidence” of a thermal effect. <\B],M1=s=

Passage 74(11/22) 84oW
Agriculturalprogress provided the stimulus necessary to set off economic expansion inmedieval France. As long as those who worked the land were barely able toensure their own subsistence and that of their landlords, all other activitieshad to be minimal, but when food surpluses increased, it became possible torelease more people for governmental, commercial, religious and culturalpursuits. s*~jvL
However,not all the funds from the agricultural surplus were actually available forcommercial investment. Much of the surplus, in the form of food increases,probably went to raise the subsistence level; an additional amount, in the formof currency gained from the sale of food, went into the royal treasury to beused in waging war. Although Louis VII of France levied a less crushing taxburden on his subjects than did England’s Henry II, Louis VII did spend greatsums on an unsuccessful crusade, and his vassals—both lay and ecclesiastic—tookover spending where their sovereign stopped. Surplus funds were claimed both bythe Church and by feudal landholders, whereupon cathedrals and castlesmushroomed throughout France. 6<Pg>Bg
Thesimultaneous progress of cathedral building and, for instance, vineyardexpansion in Bordeaux illustrates the very real competition for availablecapital between the Church and commercial interests; the former producedinestimable moral and artistic riches, but the latter had a stronger immediateimpact upon gross national product. Moreover, though all wars by definition aredefensive, the frequent crossings of armies that lived off the land andimpartially burned all the huts and barns on their path consumed considerableresources. <1 1Tqb
Sincedemands on the agricultural surplus would have varied from year to year, wecannot precisely calculate their impact on the commercial growth of medievalFrance. But we must bear that impact in mind when estimating the assets thatwere likely to have been available for investment. No doubt castle andcathedral building was not totally barren of profit (for the builders, thatis), and it produced intangible dividends of material and moral satisfactionfor the community. Even wars handed back a fragment of what they took, at leastto a few. Still, we cannot place on the same plane a primarily destructiveactivity and a constructive one, nor expect the same results from a new belltower as from a new water mill. Above all, medieval France had little room forinvestment over and above the preservation of life. Granted that war cost muchless than it does today, that the Church rendered all sorts of educational andrecreational services that were unobtainable elsewhere, and that government wasfar less demanding than is the modern state—nevertheless, for medieval men andwomen, supporting commercial development required considerable economicsacrifice. luz%FY :

Passage 84(21/22) T sW6 w
Astrophysicistswrestling with the study of a new kind of star, the flat, “two-dimensional”configurations known as accretion disks have recently gained new insights intothe behavior of these stars. Accretion disks exist in a variety of situationswhere matters swirl around a compact star such as a white dwarf star or aneutron star. Accretion disks are also suspected of playing a part in moreexotic situations, in which the central object is imagined to be a supermassiveblack hole, the ultimate form of collapsed matter, rather than a compact star.The modeling of accretion disks is still in its infancy, a situation analogousto the days when ordinary stars were modeled by using elementary scaling lawswithout benefit of knowledge of the nuclear processes that power the stars.Similarly, the basic physics of the power by which accretion disks radiate,thought to originate in a form of turbulent friction, is known only at thecrudest level. ,8 ?*U]}
Accretiondisks were first defined in the context of Cataclysmic variables. In thesesystems, matter from the outer layers of an ordinary star is attracted by thegravitational influence of a nearby orbiting white dwarf star, the matter lostfrom the ordinary star cannot strike the surface of the tiny white dwarfdirectly but settles into an orbit around the star. The viscosity in the diskthus formed causes heating, radiation, and a slow spiraling of disk matter ontothe surface of the white dwarf. abP?Dj&
Therapid advances made in x-ray astronomy in the past decade have identified asecond type of system in which accretion disks occur. In such a system, anaccretion disk whirls about a neutron star rather than a white dwarf. The innerreaches of the accretion disk extend deeply into the gravitational potential ofthe neutron star where very rapid motion is the rule. The energy released byfriction and the actual raining of the material from the disk onto the surfaceof the neutron star is so great that radiation is given off in a powerful floodof x-rays. And in at least one case, x-ray astronomers believe that the objectin the center of an accretion disk is a black hole, suggesting that a thirdsystem may exist. }mZ*f y0t
Ithad been assumed that portions of accretion disks would be unstable and that,as a result, clumping of their matter into rings would occur. There is noevidence from observation, however, that accretion disks do, in fact, sufferfrom these instabilities. In recent work, Abramowicz has shown that addedgravitational effects due to general relativity may alter the expectedNewtonian gravitational relationships in such a way that the disk remainsstable, indicating that it is possible that these predicted instabilities donot occur. _
'dy$.g
Furtherprogress toward understanding accretion disks will involve defining andproposing solutions to restricted problems just as was done in this case andwas done and continues to be done for ordinary stars. Abramowicz’ work is avaluable example of the care that must be taken before reaching conclusionsregarding accretion disks. @soW f
