01-A. What Is a Decision?



A decision is a choice m


ade from among alternative courses of action that are available. The purpose


of making a decision is to establish and achieve organizational goals and objectives. The reason for m


aking a


decision


is


that


a


problem


exists,


goals


or


objectives


are wrong,


or


som


ething


is


standing


in


the


way


of


accom


plishing them.


Thus the decision-m


aking process is fundam


ental to managem


ent. Almost everything a manager does


involves


decisions,


indeed,


som


e


suggest


that


the


m


anagement


process


is


decision


m


aking.


Although


managers cannot predict the future,


m


any of their decisions require that they consider possible future events.



Often


managers


m


ust


make a best guess at what the


future will be and try to leave as little as possib


le to


chance, hut since uncertainty is always there, risk accom


panies decisions. Som


etim


es the consequences of a


poor decision are slight; at other tim


es they are serious.


Choice is the opportunity to select am


ong alternatives. If there is no choice, there


is no decision to be


made. Decision m


aking is the process of choosing, and


m


any decisions have a broad range of choice. For


example, a student


may be able


to choose am


ong a num


ber of


different courses in order to im


plem


ent


the


decision


to


obtain


a


college


degree.


For


m


anagers,


every


decision


has


constraints


based


on


policies,



procedures, laws, precedents, and the like. These constraints exist at all levels of the organization.



Alternatives


are


the


possible


courses


of


action


from


which


choices


can


be


m


ade.


If


there


are


no


alternatives, there is no choice and, therefore, no decision. If no alternatives are seen, often it


m


eans that a


thorough


job


of


exam


ining


the


problem


s


has


not


been


done.


For


exam


ple,


managers


som


etim


es


treat


problem


s


in


an


either/or


fashion;


this


is


their


way


of


sim


plifying


com


plex


problem


s.


But


the


tendency


to


sim


plify blinds them


to other alternatives.


At the


managerial level, decision m


aking includes lim


iting alternatives as well as identifying them


, and


the range is from


highly lim


ited


to practically unlim


ited.


Decision m


akers


m


ust have som


e way of determ


ining which of several alternatives is best


--


that is,


which contributes the m


ost to


the achievem


ent of organizational goals. An organizational goal is an end or a


state


of


affairs


the


organization


seeks


to


reach.


Because


individuals


(and


organizations)


frequently


have


different


ideas


about


how


to


attain


the


goals,


the


best


choice


may


depend


on


who


m


akes


the


decision.



Frequently, departments or units within an organization m


ake decisions


that are good for them individually but


that are less than optimal for the larger organization. Called suboptim


ization, this is a trade


-off that increases


the advantages to one unit or function but decreases the advantages to another unit or function. For


exam


ple,


the


m


arketing


manager


m


ay


argue


effectively


for


an


increased


advertising


budget.


In


the


larger schem


e


of


things,


however,


increased


funding


for


research


to


im


prove


the


products


m


ight


be


more


beneficial


to


the


organization.


These


trade-offs


occur


because


there


are


m


any


objectives


that


organizations


wish


to


attain


sim


ultaneously.


Som


e


of


these


objectives


are


m


ore


im


portant


than


others,


but


the


order


and


degree


of


im


portance often vary from


person to person and from


departm


ent to department. Differen


t


managers define


the sam


e problem


in different term


s. When presented with a common case, sales m


anagers tend to see sales


problem


s, production managers see production problem


s, and so on.



The ordering and im


portance of multiple objectives is also based, in part, on the values of the decision


maker. Such values are personal; they are hard to understand, even by the individual, because they are so


dynam


ic and complex. In many business situations different people's values about acceptable degrees of risk



1


and profitability cause disagreem


ent about the correctness of decisions.


People often assum


e


that a


decision is an isolated phenom


enon.


But


from a system


s point of view,



problem


s have m


ultiple causes, and decisions have intended and unintended consequences. An


organization


is an ongoing entity, and a decision m


ade today


may have consequences far into the future. Thus the skilled


manager looks toward the future consequences of current decisions.



01-B. Secrets of Success at an Interview



The subject of today's talk is interviews.


The key words here are preparation and confidence, which will carry you far.



Do your hom


ework first.


Find out all you can about the job you are applying for and the organization you hope to work for.



Many of the em


ployers I interviewed made


the sam


e criticism


of candidates.



the


day


to


day


work


of


the


job


brings


about.


They


have


vague


notions


of



the


com


pany's


prospects’


or of 'serving the community', but have never taken the trouble to


find out


the actua


l tasks they


will be required to do.”



Do not let this be said of you. It shows an unattractive indifference to your em


ployer and to your job.



Take the time to put yourself into the interviewer's place. He wants som


ebody who is hard-working with


a pleasant personality and a real interest in the job.


Anything that you


find out about


the prospective em


ployer can be used to your advantage


during the


interview to show that you have bothered to m


aster som


e facts about the people who you hope to work for.



Write


down


(and


rem


em


ber)


the


questions


you


want


to


ask


the


interviewer(s)


so


that


you


are


not


speechless when they invite your questions. Make sure that holidays and pay are not the first


things you ask


about.


If


all


your


questions


have


been


answered


during


the


interview,


reply:



fact,


I


did


have


several


questions, but you have already answered them


all.”



Do not be afraid to ask for clarification of som


ething that has been said during the interview if you want



to be sure what was im


plied, but do be polite.


Just


before


you


go


to


the


interview,



look


again


at


the


original


advertisem


ent


that


you


answered,


any


correspondence from your prospective employer, photocopies of your letter of application or application form


and your resum


e.


Then you will rem


ember what you said and what they want. This is very im


portant if you have applied


for many jobs in a short tim


e as it is easy to becom


e confused and give an impression of inefficiency.


Make sure you know where and when you have to report


for the interview. Go to the buil


ding (but not


inside the office) a day or two before, if necessary, to find out how long the journey takes and where exactly


the place is.


Aim


to arrive five or ten m


inutes early for the actual interview, then you will have a little tim


e in hand and


you will not panic if you are delayed. You start at a disadvantage if you arrive worried and ten m


inutes late.



Dress in clean, neat, conservative clothes. Now is NOT the time


to experim


ent with the


punk look


or


(girls)


to wear low


-cut


dresses with


m


iniskirts.


Make sure


that


your


shoes,


hands


and


hair


(and


teeth)


are


clean and neat.


Have


the


letter


inviting


you


for


an


interview


ready


to


show


in


case


there


is


any


difficulty


in



2


communication.


You m


ay


find yourself facing one interviewer or a panel. The latter is far more intim


idating, but do not


let it worry you too m


uch. The interviewer will probably have a table in front of him


/her. Do not put your things


or arm


s on it.


If you have a bag or a case, put it on the floor beside your chair. Do not clutch it nervously or, worse


still, drop it, spilling everything.


Shake hands if the interviewer offers his hand first. There is little likelihood that a panel of five wants to


go though the process of all shaking hands with you in turn. So you do not be upset if no one offer


s.


Shake


hands


firm


ly


--


a


weak


hand


suggests


a weak


personality,


and


a


crushing


grip


is


obviously


painful. Do not drop the hand as soon as yours has touched it as this will seem



to show you do not like the


other person.


Speak politely and naturally even if you are feeling shy. Think before you answer any questions.


If


you


cannot


understand,


ask:



you


m


ind


rephrasing


the


question,


please?


The


question will


then be repeated in different words.


If


you


are


not


definitely


accepted


or


turned


down


on


the s


pot,


ask:



m


ay


I


expect


to


hear


the


results of this interview?


If you do receive a letter offering you the job, you


m


ust reply by letter (keep a photocopy) as soon as


possible.


Good luck!



02-A. Black Holes



What is a black hole? Well, it's difficult to answer this question, since the term


s we would norm


ally use


to describe a scientific phenom


enon are inadequate here. Astronom


ers and scientists think that a black hole


is a region of space (not a thing ) into which m


atter has fallen and from which noth


ing can escape ?not even


light. So we can't see a black hole. A black hole exerts a strong gravitational pull and yet it has no m


atter. It is


only space -- or so we think. How can this happen?


The theory is that som


e stars explode when their density increases to a particular point;


they collapse


and som


etimes a supernova occurs. From


earth, a supernova looks like a very bright light in the sky which


shines


even


in


the


daytim


e.


Supernovae


were


reported


by


astronomers


in


the


seventeenth


and


eighteenth


centuries. Som


e people think that the Star of Bethlehem could have been a supernova. The collapse of a star


may produce a White Dwarf or a neutron star


-- a star, whose m


atter is so dense that it continually shrinks by


the force of its own gravity. But if


the star is very large (m


uch bigger than our sun) this process of shrinking


may be so intense that a black hole result


s. Im


agine the earth reduced to the size of a marble, but still having


the sam


e


mass and a stronger gravitational pull, and you have som


e idea of


the


force of a black hole. Any


matter near the black hole is sucked in. It is im


possible to say what happens inside a black hole. Scientists


have


called


the


boundary


area


around


the


hole


the



horizon.


We


know


nothing


about


events which


happen once objects pass this boundary. But in theory, m


atter must behave very differently inside the hole.


For exam


ple, if a man fell into a black hole, he would think that he reached the center of it very quickly.



However an observer at the event horizon would think that the man never reached the center at all. Our space


and time laws don't seem to apply to objects in the area of a black hole. Einstein's relativity theory is the only



3


one which can explain such phenom


ena. Einstein claim


ed that


m


atter and energy are in


terchangeable, so that


there is no


e and space. There are no constants at all, and


m


easurem


ents of


tim


e and space


depend on the position of


the observer. They are relative. We do not yet


fully understand the im


plications of


the


relativity


theory;


but


it


is


interesting


that


Einstein's


theory


provided


a


basis


for


the


idea


of


black


holes


before astronomers started to find som


e evidence for their existence. It is only recently that astronomers have


begun specific research into black holes. In August 1977, a satellite was launched to gather data about the 10


million black holes which are thought to be in the Milky Way. And astronom


ers are planning a new observatory


to study the individual exploding stars believed to be black holes,


The


m


ost


convincing


evidence


of


black


holes


com


es


frown


research into


binary star system


s.


Binary


stars,


as


their


nam


e


suggests,


are


twin stars whose


position


in space


affects


each


other.


In


som


e


binary


system


s, astronom


ers have shown that there is an invisible com


panion s


tar, a


can see in the sky. Matter from the one which we can see is being pulled towards the companion star. Could


this invisible star, which exerts such a great force, be a black hole? Astronomers have evidence of a few other


stars too, which m


ight have black holes as companions.


The story


of


black


holes


is


just


beginning.


Speculations


about


them


.


are


endless.


There


m


ight


be


a


massive black hole at the center of our galaxy swallowing up stars at a very rapid rate. Mankind m


ay one day


meet this


fate. On


the other hand, scientists have suggested that very advanced technology could one day


make use of


the energy of black holes


for


mankind. These speculations sound like science fiction. But


the


theory of black holes in space is accepted by m


any serious scientists and astronom


ers. They show us a world


which operates in a totally different way from


our own and they question our most basic experience of space


and tim


e.



02-B. Worlds within Worlds



First of all let us consider the earth


(that is to say, the world) as a planet revolving round the sun. The


earth


is


one


of


nine


planets which


m


ove


in


orbit


round


the sun.


These


nine


planets,


together with


the sun,



make


up


what


is


called


our solar system.


How


this wonderful system



started


and


w


hat


kept


it


working with


such wonderful accuracy is largely a m


ystery but astronomers tell us that it is only one of


millions of sim


ilar


system


s in space, and one of the sm


allest.


The stars which we see glittering in the sky on a dark and cloudless night are alm


ost certainly the suns


of other solar system


s


m


ore or less like our own, but they are so far away in space that it is unlikely that we


shall ever get to


know very m


uch about


them


. About our own solar system, however, we are learning more


every day.


Before


the


Am


erican


and


Russian


astronauts


m


ade


their


thrilling


journeys


into


outer


space


it


was


difficult


for


us


to


realise


what


our


earth


looked


like


from



hundreds


of


thousands


of


m


iles


away,


but


the


photographs which the astronauts were able to take show


us the earth in space looking not very different from


what


the


m


oon


looks


like when we


look


at


it


from



the


earth.


The


earth


is,


however,


very


different


from


the


moon, which the Am


erican astronauts have found to be without life or vegetation, whereas our e


arth is very


much alive in every respect. The


moon,


by the way, is called a satellite because it goes round our earth as


well as round the sun. In other words, it goes round the sun with our earth.


The surface of our earth is covered by m


asses of land and


larger areas of water. Let us consider the



4


water areas first. The total water area is about three tim


es as large as the land area. The very large separate


areas of water are called


and the lesser areas are called



In


m


ost


of


the oceans and seas som


e of


the water is found to be


flowing in a particular direction


--


that is to say, from


one part towards another part of the ocean or sea concerned. The water which is flowing


in this m


anner is said to be moving as a


ands of currents in the waters of the


oceans


and


seas,


but


only


certain


of


the


stronger


and


better


marked


currents


are specially


nam


ed


and


of


great


im


portance.


These


currents


are


im


portant


because


they


affect


the


clim


ate


of


the


land


areas


close


to


where they flow and also because they carry large quantities of


m


icroscopic anim


al and vegetable life which


form


s a large part of the food for fishes.


The nature and characteristics of the surface of the land areas of the earth vary a great deal from area


to


area


and


from


place


to


place.


The surface


of


som


e


areas


consists


largely


of


high


m


ountains


and


deep


valleys


whilst,


in


other


areas,


most


of


the


surface


consists


of


plains.


If


one


made


a


journey


over


the


Continents one would find every kind of surface including


mountain ranges, plains, plateaux, deserts, tropical


forestlands and em


pty areas covered perm


anently by ice and snow.


When thinking and learning about the world we should not forget that our world is the hom


e of a very


great many different people


-- peoples with different coloured skins, living very different lives and having very


different


ideas


about


a


great


many


im


portant


things


such


as


religion,


governm


ent,


education


and


social


behaviour.


The circum


stances under which different people live make a great difference between the way in which


they


live


and


the way


in which we


live,


and


it


ought


to


be


our


business


to


try


to


understand


those


different


circum


stances so that we can better understand people of other lands. Above all, we should avoid deciding


what we think about people different


from ourselves without first having learned a great deal about them


and


the kind of lives they have to live. It is true to say that


the


more we learn about other people,


the better we


understand their ideas and, as a rule, the better we like those people them


selves.




03-A. Euthanasia: For and Against




We


m


ustn't


delay


any


longer ...


swallowing


is


difficult ...


and


breathing,


that's


also


difficult.


Those


muscles are weakening too ... we m


ustn't delay any longer.”



These were


the words


of


Dutchm


an


Cees


van


Wendel


de


Joode


asking


his


doctor


to


help


him



die.


Affected with a serious disease, van Wendel was no longer able to speak clearly and he knew there was no


hope of recovery and that his condition was rapidly deteriorating.



Van


Wendel's


last


three


m


onths


of


life


before


being


given


a


final,


lethal


injection


by


his


doctor were


film


ed and first shown on television last year in the Netherlands. The programme has since been bought by 20


countries and each tim


e it is shown, it starts


a nationwide debate on the subject.


The Netherlands is the only country in Europe which perm


its euthanasia, although it is not


technically


legal


there.


However,


doctors


who


carry


out


euthanasia


under


strict


guidelines


introduced


by


the


Dutch


Parliam


ent


tw


o years ago are usually not prosecuted. The guidelines dem


and that the patient is experiencing


extrem


e


suffering,


that


there


is


no


chance


of


a


cure,


and


that


the


patient


has


m


ade


repeated


requests


for


euthanasia. In addition to this, a second doctor must confirm that these criteria have been m


et and the death



5


must be reported to the police departm


ent.


Should doctors be allowed to take the lives of others? Dr. Wilfred van Oijen, Cees van Wendel's doctor,


explains how he looks at the question:



m planning to murder a crowd of people with a m


achine gun. In that case, killing is


the worst thing I can im


agine. But that's entirely different from my work as a doctor. I care for people and I try


to ensure that they don't suffer too m


uch. That'


s a very different thing.”



Many people, though, are totally against the practice of euthanasia. Dr. Andrew Ferguson, Chairm


an of


the organisation Healthcare Opposed to Euthanasia, says that


the


patient


is


actually


asking


for


is


som


ething


else.


They


m


ay


want


a


health


professional


to


open


up


communication for them


with their loved ones or fam


ily


--


there's nearly always another question behind the


question.”



Britain also has a strong tradition


of hospices


-- special hospitals which care only for the dying and


their special needs. Cicely Saunders, President of the National Hospice Council and a founder m


ember of the


hospice


m


ovement,


argues


that


euthanasia


doesn't


take


into


account


that


there


are ways


of


caring


fo


r


the


dying. She is also concerned that allowing euthanasia would underm


ine the need for care and consideration of


a wide range of people:


that


they


are


burdens,


and


therefore


that


they


ought


to


opt


out.


I


think


that


anything


that


legally


allows


the


shortening of life does m


ake those people more vulnerable.”



Many


find


this


prohibition


of


an


individual's


right


to


die


paternalistic.


Although


they


agree


that


life


is


im


portant


and


should


be


respected,


they


feel


that


the


quality


of


life


should


not


be


ignored.


Dr.


van


Oijen


believes


that


people


have


the


fundam


ental


right


to


choose


for


them


selves


if


they want


to


die:



those


people who oppose euthanasia are telling m


e is that dying people haven't the right. And that when people are


very ill, we are all afraid of


their death. But there are situations where death is a friend. And in those cases,



why not?



But


ight cause strong em


otion. The film sh


owing Cees van Wendel's


death was both moving and sensitive. His doctor was clearly a fam


ily friend; his wife had only her husband's


interests at heart. Som


e, however, would argue that it would be dangerous to use this particular exam


ple to


support


the


case


for


euthanasia.


Not


all


patients


would


receive


such


a


high


level


of


individual


care


and


attention.



03-B. Advantage Unfair



According


to


the


writer


Walter


Ellis,


author


of


a


book


called


the


Oxbridge


Conspiracy,


Britain


is still


dom


inated by the old-boy network: it isn't what you know that


m


atters, but who you know. He claim


s that at


Oxford and Cambridge Universities (Oxbridge for short) a few select people start on an escalator ride which,



over


the


years,


carries


them



to


the


tops


of


British


privilege


and


power.


His


research


revealed


that


the


top


professions all continue to be dominated, if not 90 per cent, then 60 or 65 per cent, by Oxbridge graduates.



And yet, says Ellis, Oxbridge graduates m


ake up only two per cent of the total number of students who


graduate from Britain's universities. Other researches also seem



to support his belief that Oxbridge graduates


start with an unfair advantage in the em


ployment


market. In the law, a recently published report showed that


out of


26 senior judges appointed to


the High Court last year, all of


them


went to private schools and 21 of



6


them


went to Oxbridge.


But can this be said to am


ount to a conspiracy? Not according to Dr. John Rae, a form


er headm


aster


of one of Britain's leading private schools, Westm


inster:



there was a bias in som


e key areas of British life, but


that bias has now gone.



Som


e


tim


e


ago


--


in


the


60s


and


before


?entry


to


Oxford


and


Cam


bridge


was


not


entirely


on


m


erit.


Now,


there's absolutely no question in any objective observer's


m


ind that, entry to Oxford and Cam


bridge is fiercely


co m


petitive.


However,


m


any


would


disagree


with


this.


For,


although


over


three


-quarters


of


British


pupils


are


educated in state schools, over half the students that go to Oxbridge have been to private, or



Is this because pupils from


Britain's private schools are m


ore intelligent than those from


state schools, or are


they sim


ply better prepared?


On average, about $$ 5,000 a year is spent on each private school pupil,


m


ore


than twice the amount


spent on state school pupils. So how can the state schools be expected to com


pete with the private schools


when they have far fewer resources? And how can they prepare their pupils for the special entrance exam



to


Oxford


University, which requires extra preparation, and for which m


any public school pupils traditionally stay


at school and do an additional term?



Until


recently,


many


blamed


Oxford


for


this


bias


because


of


the


university's


special


entrance


exam


(Cam


bridge abolished its entrance exam


in 1986). But last February, Oxford University decided to abolish the


exam



to


encourage


m


ore


state


school


applicants.


From



autum


n


1996,


Oxford


University


applicants,


like


applicants


to


other


universities,


will


be


judged


only


on


their


A


level


results


and


on


their



perform


ance


at


interviews, although som


e departments m


ight still set special tests.


However, som


e argue that there's nothing wrong in having elite places of learning, and that by their very


nature, these places should not be easily accessible. Most countries are run by an elite and have centres of


academ


ic excellence from


which the elite are recruited. Walter Ellis accepts that this is true:



in


France,


for


exam


ple,


there


are som


ething


like


40


equivalents


of


university, which


provide


this


elite through a m


uch broader base. In Am


erica you've got the Ivy League, centred on Harvard and Yale, with


Princeton and Stanford and others. But again, those universities together


-- the elite universities -- are about


ten or fifteen in num


ber, and are being pushed along from behind by other great universities like, for exam


ple,


Chicago


and


Berkeley.


So


you


don't


have


just


this


narrow


concentration


of


two


universities


providing


a


constantly replicating elite.”



When it com


es to Oxford and Cambridge being elitist because of the number of private school pupils


they


accept,


Professor Stone


of


Oxford


University


argues


that


there


is


a


simple


fact


he


and


his


associates


cannot ignore:



certain


schools


do


better


than


others


then we


just


have


to


accept


it.


We


cannot


be


a


place



for


rem


edial education. It's not what Oxford is there to do.”



However, since


academ


ic


excellence


does


appear


to


be


related


to


the


amount


of


money


spent


per


pupil, this does seem


to imply that Prim


e Minister John Major's vision of Britain as a classless society is still a


long way off. And it


m


ay be worth rem


embering that while John Major didn't him


self go to Oxbridge,


m


ost of


his m


inisters did.

04-A. Slavery on Our Doorstep


There are estim


ated to be


more than


20,000 overseas dom


estic servants working in Britain (the exact



figure is not known because the Hom


e Office, the Governm


ent department that deals with this, does not keep


statistics). Usually, they have been brought over by foreign businessm


en, diplomats or Britons returning from


abroad. Of these 20,000, just under 2,000 are being exploited and abused by their em


ployers, according to a


London-based cam


paigning group which helps overseas servants working in Britain.


The


abuse


can


take several


form


s.


Often


the


dom


estics


are


not


allowed


to


go


out,


and


the


y


do


not


receive any paym


ent. They can be physically, sexually and psychologically abused. And


they can have their


passports removed, making leaving or


possible.


The sad


condition


of


wom


en


working


as


dom


estics


around


the world


receiv


ed


m


uch


m


edia


attention


earlier this year in several highly publicised cases. In one of them, a Filipino m


aid was executed in Singapore


after being convicted of m


urder, despite protests from various quarters that her guilt had not been adequately


established.


Groups like


Anti-Slavery


International say


other,


less


dram


atic,


cases


are


equally


deserving


of


attention, such as that of Lydia Garcia, a Filipino m


aid working in London:



was


hired


by


a


Saudi


diplom


at


directly


from


the


Philippines


to


work


in


London



in


1989.


I


was


supposed to be paid $$ 120 but I never received that amount. They always threatened that they would send m


e


back to my country.”



Then there is the case of Kumari from Sri Lanka. The main breadwinner in her fam


ily, she used to work


for a very low wage at a tea factory in Sri Lanka. Because she found it difficult to


feed her four children, she


accepted a job working as a dom


estic in London. She says she felt like a prisoner at the London house where


she worked:



-- ever, no breaks at all, no proper food. I


didn't have


m


y own room


; I slept on a shelf


with a spad0 of only three feet above m


e. I wasn't allowed to talk to anybody. I wasn't even allowed to open


the window. My employers always threatened to report me to the Home Office or


the police.”



At the end of


1994


the British Governm


ent introduced new m


easures to help protect dom


estic workers


from


abuse


by


their


em


ployers.


This


included


increasing


the


m


inim


um


age


of


employees


to


18,


getting


em


ployees


to


read


and,


understand


an


advice


leaflet,


getting


em


ployers


to


agree


to


provide


adequate


maintenance


and


conditions,


and


to


put


in


writing


the


m


ain


term


s


and


conditions


of


the


job


(of


which


the


em


ployees should see a copy).


However, m


any people doubt whether this will successfully reduce the incidence of abuse. For the main


problem



facing overseas m


aids and dom


estics who try to com


plain about cruel living and working conditions


is that they do not have independent immigrant status and so cannot change em


ployer. (They are allowed in


the


United


Kingdom


under


a


special


concession


in


the


imm


igration


rules


which


allows


foreigners


to


bring


dom


estic staff with them


.) So if they do com


plain, they risk being deported.


Allowing dom


estic workers the freedom


to seek the sam


e type of work but with a different em


ployer, if


they so choose, is what groups like Anti-Slavery International are campaigning the Governm


ent


for. It is, they


say, the right to change em


ployers which distinguishes em


ployment from slavery.


04-B. Return of The Chain Gang


Eyewitnesses say it was a scene straight out of a black and white


m


ovie


from


the 1950s. As the sun


rose over the fields of Huntsville, Alabam


a, in the American South, the convicts got down from the trucks that


had brought


them



there. Watched over by guards with guns, they raised their legs in unison and m


ade their



8


way


to


the


edge


of


the


highway,


Interstate


65.


The


BBC's


Washington


correspondent


Clare


Bolderson was


there and she sent this report:



s


with


the words



Gang'


on


their


backs


and,


in



groups


of


five,


were


shackled together in leg irons joined by an eight-foot chain. The prisoners will work for up to


90 days on the


gang: they'll clear ditches of weeds and m


end fences along Alabam


a's m


ain roads. While they are working on


the


gang,


they


抣


l


also


live in som


e


of


the


harshest


prison conditions


in


the


United


States.


There'll


be


no


televisions or phone calls; m


any other day


-to-


day privileges will be denied.”



The authorities in Alabam


a say there is a lot


of support


for


the re-introduction


of chain gangs in the


State


after


a


gap


of


30


years


(the


last


gangs were


abolished


in


Georgia


in


the


early


1960s).


Many


people


believe it is an effective way to get crim


inals to pay back their debt to society.


The prisoners stay shackled when they use toilets. They reacted sharply to the treatm


ent they are given:


Prisoner one:


als now.


Prisoner two:


barrassing.”



Prisoner three:


Six


out


of


every


ten


prisoners


in chains


are


black, which


is why


the


chain


gangs


call


up


im


ages


of


slavery in centuries gone by, when black people were brought from Africa in leg irons and


m


ade


to work in


plantations owned by white m


en. Not surprisingly, although three- quarters of the white population of Alabama


supports


chain


gangs,


only


a


sm


all


num


ber


of


black


people


do.


Don


Claxton,


spokes


m


an


for


the


State


Governm


ent of Alabama, insists that the system


is not racist:



ething that's done for racial reasons, for political reasons. This is som


ething that's going


to help save the people of Alabama tax


money because they don't have to pay as m


any officers to work on


the highways. And it's going to help clean up our highways and it's going to help clean up the


State.”



However,


the


re-introduction


of


these


m


easures


has


caused


a


great


deal


of


strong


disagreem


ent.


Hum


an rights organizations say that putting prisoners in chains is not only inhum


ane but also ineffective. Alvin


Bronstein, m


ember of the Civil Liberties


Union, says that study after study has shown that you cannot prevent


people


from


committing


crim


es


by


punishm


ent


or


the


threat


of


punishm


ent:



they


will


do


is


m


ake


prisoners m


ore angry,


more hostile, so that when they get out of prison, they will increase the level of


their


crim


inal behaviour.”



Civil


liberties


groups


say


that


chaining


people


together


doesn't


solve


the


causes


of


crim


e,


such


as


poverty


or


disaffection


within society.


What


it


does


is


punish


prisoners


for


the


ills


of


society.


They say


the


practice takes the United States back to the Middle Ages, and that it is a sham


e to American society. But that


抯



not


an


argum


ent


likely


to


win


favour


am


ong


many


people


in


the


Deep


South


of


the


United


States.


Alabam


a's experim


ent is to be widened to include


m


ore prisoners, and other States, such as Arkansas and


Arizona, will very probably introduce their own chain gang schem


es.


05-A. The New Music


The


new


m


usic


was


built


out


of


materials


already


in


existence:


blues,


rock'n'roll,


folk


music.


But


although the form


s remained, som


ething completely new and original was m


ade out of


these older elem


ents


-- more original, perhaps, than even the new m


usicians them


selves yet realize. The transform


ation took place


in


1966--1967.


Up


to


that


tim


e,


the


blues


had


been


an


essentially


black


m


edium


.


Rock'n'roll,


a


blues


derivative, was


rhythm


ic


dance


m


usic.


Folk


m


usic,


old


and


m


odern,


was


popular


am


ong


college


students.



The


three


form


s


rem


ained


m


usically


and


culturally


distinct,


and


even


as


late


as


1965,


none


of


them



were



9


expressing


any


radically


new


states


of


consciousness.


Blues


expressed


black


soul;


rock


was


the


beat


of


youthful energy; and folk music expressed anti-war sentim


ents as well as love and hope.


In 1966 -- 1967 there was spontaneous transformation. In the United States, it originated with youthful


rock groups playing in San Francisco. In England, it was led by the Beatles, who were already established as


an extrem


ely fine and highly individual rock group. What happened, as well as it can be put into words, was


this. First, the separate musical traditions were brought together. Bob Dylan and the Jefferson Airplane played


folk rock, folk ideas with a rock beat. White rock groups began experim


enting with the blues. Of course, white


musicians had always played the blues, but essentially as im


itators of the Negro style; now it began to be the


white bands’


own m


usic. And all of


the groups


m


oved


towards a broader eclecticism and synthesis. They


freely


took


over


elem


ents


from


jazz,


from


American


country


m


usic,


and


as


tim


e


wen


t


on


from


even


more


diverse


sources.


What


developed


was


a


m


usic


readily


taking


on


various


form


s


and


capable


of


an


almost


lim


itless range of expression.


The second thing that happened was that all the


m


usical groups began using the full range of electric


instrum


ents and the technology of electronic amplifiers. The electric guitar was an old instrum


ent, but the new


electronic effects were altogether different


-- so different that a new listener in 1967 might well feel that there


had never been any sounds like that in the world before. Electronics did, in fact,


make possible sounds that


no instrum


ent up to that tim


e could produce. And in studio recordings, new techniques m


ade possible effects


that


not


even


an


electronic


band


could


produce


live.


Electronic


am


pli


fiers


also


m


ade


possible


a


fantastic


increase in volum


e, the


m


usic becom


ing as loud and penetrating as the hum


an ear could stand, and thereby


achieving a


total participants, feeling the m


usic in all of their senses and all of their bones.


Third, the


music becom


es a


m


ulti


-m


edia experience; a part of a total environm


ent. The walls of


the


ballroom


s were covered with changing patterns of light, the beginning of the new art of the light show. And the


audience did not sit, it danced.


With records at home, listeners im


itated these lighting effects as best they


could,


and


heightened


the whole experience


by


using


drugs.


Often


m


usic


was


played


out


of


doors,


where


nature provided the environm


ent.



05-B. Different Types of Composers


I


can


see


three


different


types


of


composers


in


m


usical


history,


each


of


whom



creates


m


usic


in


a


som


ewhat different fashion.


The type that has fired public im


agination


most is that of


the spontane


ously inspired composer --


the


Franz


Schubert


type,


in


other


words.


All


com


posers


are


inspired,


of


course,


but


this


type


is


more


spontaneously inspired. Music sim


ply wells out of him. He can't get it


down on paper fast enough. You can


alm


ost tell this type of composer by his fruitful output. In certain months, Schubert wrote a song a day. Hugo


Wolf did the sam


e.


In a sense, m


en of this kind begin not so m


uch with a m


usical them


e as with a com


pleted composition.


They invariably work best in the shorter form


s. It is m


uch easier to im


provise a song than it is to im


provise a


sym


phony.


It isn't easy to be inspired in that spontaneous way for long periods at a stretch. Even Schubert


was m


ore successful in handling the shorter form


s of m


usic. The spontaneously inspired m


an is only one type


of composer, with his own lim


itations.


Beethoven belongs to the second type


--


the constructive type, one m


ight call it. This type serves as



10


an


exam


ple


of


m


y


theory


of


the


creative


process


in


m


usic


better


than


any


other,


because


i


n


this case


the


com


poser really does begin with a m


usical them


e. In Beethoven's case there is no doubt about it, for we have


the


notebooks


in which


he


put


the


them


es


down.


We


can


see


from



his


notebooks how


he worked


over his


them


es -- how he would not let them



be until they were as perfect as he could


m


ake them. Beethoven was


not a spontaneously inspired com


poser in the Schubert sense at all. He was the type that begins with a them


e;


makes it a prelim


inary idea; and upon that composes a m


usical work, day after day, in painstaking fashion.


Most com


posers since Beethoven's day belong to this second type.


The third type of composer I can only call, for lack of a better name,


the


traditionalist type. Men like


Palestrina and Bach belong in this category. They both are characteristic of the kind of composer who is born


in a particular period of musical history, when a certain m


usical style is about to reach its fullest developm


ent.


It is a question at such a tim


e of creating music in a well-known and accepted style and doing it in a way that


is better than anyone has done it before you.


The traditionalist type of composer begins with a pattern rather than with a them


e. The creative act with


Palestrina is not the


thematic conception so


m


uch as


the personal treatment


of a well- established pattern.


And


even


Bach, who com


posed


forty


-eight


of


the


most


various


and


inspired


them


es


in his


Well


Tempered


Clavichord,


knew in advance the general form


al


mold that they were to fill. It goes without saying that we are


not living in a traditionalist period nowadays.


One m


ight add, for the sake of completeness, a fourth type of composer -- the pioneer type: men like


Gesualdo in the seventeenth century, Moussorgsky and Berlioz in the nineteenth, Debussy and Edgar Varese in


the twentieth. It is difficult to summarize the com


posing m


ethods of so diversified a group. One can safely say


that


their approach to com


position is the opposite of the traditionalist type. They clearly oppose conventional


solutions of


m


usical problem


s. Inm


any ways,


their attitude is experim


ental ?they seek to add new harm


onies,


new


sonorities,


new


form


al


principles.


The


pioneer


type


was


the


characteristic


one


at


the


turn


of


the


seventeenth century and also at the beginning of the twentieth century, but it is m


uch les


s evident today.



06-A. Improving Industrial E


fficiency through Robotics


Robots,


becom


ing


increasingly


prevalent


in


factories


and


industrial


plants


throughout


the


developed


world, are programmed and engineered to perform industrial tasks without hum


an inte


rvention.


Most of


today's robots are em


ployed in


the automotive industry, where they are programmed to


take


over such jobs as welding and spray painting automobile and


truck bodies. They also load and unload hot,


heavy m


etal form


s used in m


achines casting autom


obile and truck fram


es.


Robots, already taking over hum


an tasks in the automotive field, are beginning to be seen, although to


a


lesser


degree,


in


other


industries


as


well.


There


they


build


electric


m


otors,


s


m


all


appliances,


pocket


calculators,


and


even watches.


The


robots


used


in


nuclear


power


plants


handle


the


radioactive


m


aterials,


preventing


hum


an


personnel


from


being


exposed


to


radiation.


These


are


the


robots


responsible


for


the


reduction in job-related injuries in this new industry.


What


makes


a


robot


a


robot


and


not


just


another


kind


of


automatic


m


achine?


Robots


differ


from


automatic


machines in that after completion of one specific task, they can be reprogrammed by a com


puter


to


do


another


one.


As


an


example,


a


robot


doing


spot


welding


one


month



can


be


reprogrammed


and


switched


to


spray


painting


the


next.


Automatic


machines,


on


the


other


hand,


are


not


capable


of


many


different uses; they are built to perform only one task.



11


The next generation of robots will


be


able


to see


objects, will


have


a


sense


of


touch,


and will


m


ake


critical decisions. Engineers skilled in m


icroelectronics and com


puter technology are developing artificial vision


for


robots.


With


the


ability


to



robots


can


identify


and


inspect


one specific


class


of


objects


out


of


a


stack of different kinds of materials. One robot vision system


uses electronic digital cam


eras containing m


any


rows of light-sensitive m


aterials. When light


from an


object such as a m


achine part strikes the cam


era,


the


sensitive


m


aterials


m


easure


the


intensity


of


light


and


convert


the


light


rays


into


a


range


of


num


bers.


The


numbers


are


part


of


a


grayscale system



in


which


brightness


is


m


easured


in


a


range


of


values.


One scale


ranges from 0 to 15, and another from 0 to 255. The 0 is represented by black. The high


est num


ber is white.


The num


bers in between represent different shades of gray. The com


puter then


makes the calculations and


converts the num


bers into a picture that shows an im


age of the object in question. It is not yet known whether


robots will one day have vision as good as hum


an vision. Technicians believe they will, but only after years of


developm


ent.


Engineers working on other advances are designing and experim


enting with new types of


m


etal hands


and


fingers,


giving


robots


a


sense


of


touch.


Other


engineers


are writing


new


program


s


allowing


robots


to


make decisions such as whether. to discard defective parts in finished products. To do this, the robot will also


have to be capable of identifying those defective parts.


These future robots, assem


bled with a sense of touch and the ability to see and m


ake decisions, will


have plenty of work to do. They can be used to explore for


minerals on the ocean floor or in deep areas of


mines too dangerous for hum


ans to enter. They will work as gas station attendants, firem


en, housekeepers,



and


security


personnel.


Anyone


wanting


to


understand


the


industry


of


the


future


will


have


to


know


about


robotics.



06-B. Predicting Earthquakes


Can


earthquakes


be


predicted?


Scientists


are


working


on


program


s


to


predict


where


and


wh


en


an


earthquake


will


occur.


They


hope


to


develop


an


early


warning


system


that


can


be


used


to


forecast


earthquakes so that lives can be saved.


Earthquakes are the most dangerous and deadly of all natural events. They occur in m


any parts of the


world. Giant earthquakes have been recorded in Iran, China, Guatem


ala, Chile, India, and Alaska. Two of the


biggest earthquakes that were ever recorded took place in China and Alaska. These earthquakes


m


easured


about 8.5 on the Richter Scale. The Richter Scale was devised by Charles Richter in 1935, and compares the


energy


level


of


earthquakes.


An


earthquake


that


measures


a


2


on


the


scale


can


be


felt


hut


causes


little


dam


age.


One


that


m


easures


4.5


on


the


scale


can


cause


slight


dam


age,


and


an


earthquake


that


has


a


reading of over 7 can cause m


ajor damage. It is important to note that a reading of 4 indicates an earthquake


ten times as strong as one with a reading of


ists want to be able


to


predict


those earthquakes that


have a reading of over 4 on the Richter Scale.


How do earthquakes occur? Earthquakes are caused by the shifting of rocks along cracks, or faults, in


the


earth's


crust.


The


fault


is


produced when


rocks near


each


other


are


pulled


in


different


directions.


The


best-known fault in North Am


erica is the San Andreasfault in the state of California in the United States.


The nations that are actively involved in earthquake prediction program


s include Japan, China, Russia,



and


the


United


States.


These


countries


have


set


up


seism


ic


networks


in


areas


of


their


co


untries


where


earthquakes are known to occur. These networks are on the alert for warning signs that show the weakening



12


of rock layers that can precede an earthquake. Many kinds of seism


ic instrum


ents are used by the networks to


monitor


the


m


ovem


ents


of


the


earth's


crust.


The scientists


also


check water in


deep wells.


They watch


for


changes in the water level and temperature that are associated with m


ovem


ent along faults.



Scientists in China, Russia, and the United States m


easure radon in ground water. Radon is a gas that


com


es


from


the


radioactive


decay


of


radium



in


rocks.


The


gas


flows


through


the


ground


and


dissolves in


underground stream


s and wells. Scientists speculate that the amount of radon increases in the ground when


rocks layers shift, exposing new rock, and thus m


ore radon. Chinese and Russian scientists have reported that


in places where stress is building up, the radon levels of the water build up too. When the radon levels of the


water subside and drop back to normal readings, an earthquake m


ay occur. United States scientists have also


placed radon monitoring stations in earthquake zones, particularly California. However, all the scientist


s agree


that


more data is necessary to prove


that radon levels in water are associated with the possible bir


th of an


earthquake.


Earthquake prediction is still a young science. Everyone agrees that earthquakes cannot be predicted


with


any


reliability.


Scientists


have


only


a


partial


understanding


of


the


physical


processes


that


cause


earthquakes. Much m


ore research has to be done. New and m


ore up-to-date


m


ethods have to be found for


collecting


earthquake


data


and


analyzing


it.


However,


scientists


have


had


som


e


success


in


predicting


earthquakes. Several sm


all earthquakes were predicted in New York State, in the eastern part of the


United


States.


Chinese


scientists


predicted


a


m


ajor


one


in


Haicheng


in


1975,


and


Russian scientists


predicted


a


major one in Garm


in 1978. While this is a sm


all start, it is still a beginning.


07-A. Leisure and Leadership


Observations and research findings indicate that people in advanced industrial societies are increasingly


concerned with


opportunities


for


leisure


and what


they


can


do


in


their


leisure


tim


e.


The


importance


people


attach to paid holidays and the rapid developm


ent of services


for m


ass entertainm


ent and recreation are signs


of this increasing concern.


The term



to define. It covers a very wide scope such as living environm


ent,


health, em


ployment, food, family life, friends, education, m


aterial poss


essions, leisure and recreation, and so


on. Generally speaking, the quality of life, especially as seen by the individual, is m


eaningful in term


s of


the


degree to which these various areas of life are available or provide satisfaction to the individual.


As


activity


carried


out


as


one


thinks


fit


during


one's spare


tim


e,


leisure


has


the


following


functions:


relaxation, recreation and entertainm


ent, and personal developm


ent. The im


portance of thesevaries according


to the nature of one's job and one's life-style. Thus, people who need to exert


m


uch energy in their work will


find relaxation


most desirable in leisure. Those with a better education and in professional occupations m


ay


tend more to seek recreation and personal developm


ent (e.g., cultivation of skills


and hobbies) in leisure.


The specific use


of


leisure


varies


from



individual


to


individual. Even


the sam


e


leisure


activity


m


ay


be


used differently by different individuals. Thus, the following are possible uses of television watching, a popular


leisure activity: a change of experience to provide



the stress and strain of work; to learn more


about


what


is


happening


in


one's


environm


ent;


to


provide


an


opportunity


for


understanding


oneself


by


com


paring other people


抯



life experiences as portrayed in the programmes.


In


an


urban


society


in


which


highly


structured,


fast-paced


and


stressful


work


loom


s


large


in


life,


experiences of a different nature, be it television watching or bird-watching, can lead to a self-renewal and a


more



13


Since leisure is basically self-determ


ined, one is able to take to one's interest


s and preferences and


get involved in an activity in ways that will bring enjoym


ent and satisfaction.



Our


likes


and


dislikes,


tastes


and


preferences


that


underlie


our


choices


of


such


activities


as


reading


books,


going


to


the


cinem


a,


camping,


or


certain


cultural


pursuits,


are


all


related


to


social


contexts


and


learning experiences. We acquire interests in a variety of things and subject


s from our fam


ilies, schools, jobs,



and the mass m


edia. Basically, such attitudes am


ount to a recognition that leisure is an im


portant area of life


and a belief that leisure can and should be put to good use.


Professional workers in recreation services


, too, will find that


to impart positive leisure attitudes to


the


general public is essential for


motivating them


to use their leisure in creative and satisfying ways. Hence, it


can be argued that the people with whom


we com


e into contact in these various contexts are all likely to have


exerted som


e influence in shaping our attitudes, interests and even skills relevant to how we handle leisure.



Influence of this kind is a form


of leadership.


Parents, teachers in schools, work associates and communicators in or using the m


ass


m


edia are all


capable of arousing our potential interests. For example, the degree to which and the ways in which a school


encourages participation in gam


es, sports and cultural pursuits are likely to contribute to the shaping of leisure


attitudes on the part of the students.


Schools


usually


set


as


their


educational


objective


the


attainm


ent


of


a


balanced


developm


ent


of


the


person.


The


m


ore


seriously


this


is


sought,


the


more


likely


positive


attitudes


towards


leisure


as


well


as


academ


ic work will be encouraged.



07-B. The Tim


e Message


You m


ay have been exposed to this idea before, but this tim


e


try to hear. There is a m


essage that is


trying to reach you, and it is im


portant that it get through loud and clear. The m


essage?


Tim


e m


anagement!


Tim


e is elusive and tricky. It is the easiest thing in the world to waste


--


the


most difficult to control.


When you look ahead, it m


ay appear you have m


ore than you need. Yet it has a way of slipping through your


fingers like quicksand. You


m


ay suddenly find


that


there is no way to stretch


the little time you have left


to


cover all your obligations. For example, as a beginning student looking ahead to a full term you may feel that


you have an oversupply of tim


e on your hands. But toward the end of the term you may panic because tim


e is


running out. The answer?


Control!


Tim


e is dangerous. If you don'


t control it, it will control you. If you don'


t


make it work for you, it will


work against you. You m


ust becom


e the m


aster of tim


e, not the servant.


Study hard and play hard is an old proverb, but it still makes sense. You have plenty of tim


e for classes,



study, work, and play if you use your tim


e properly. It is not how m


uch tim


e you allocate for study that counts


but how m


uch you learn when you do study.


Too


m


uch wasted tim


e is bad m


edicine. The m


ore tim


e you waste, the easier it is to continue wasting


tim


e. Soon, doing nothing becom


es a habit you can't break. It becomes a drug. When this happens, you lose


your feeling of accomplishm


ent and you fall by the wayside. A full schedule is a good schedule.


Som


e


students


refuse


to


hear


the


tim


e


message.


They


refuse


to


accept


the


fact


that


college


life


dem


ands som


e degree of


tim


e control. There is no escape. So what's the next step? If you seriously wish to



14


get


the time


message, this passage will give it to you. Rem


ember


?it will not only im


prove your grades but


also free you to enjoy college life m


ore.


Message 1. Tim


e is valuable -- control it from the beginning.


Tim


e is today, not


tomorrow or next week. Start your plan at


the beginning of the term


and readjust it


with each new project. Thus you can spread your work tim


e around a little.


Message 2. Get the notebook habit.


Go and buy a pocket-size notebook. There are


m


any varieties of these special notebooks. Select the


one you like best. Use it to schedule your study tim


e each day. You can also use it to note important dates,


appointments, addresses, and telephone num


bers. Keep it with you at all tim


es.


Message 3. Prepare a weekly study schedule.


The


m


ain


purpose


of


the


notebook


is


to


help


you


prepare


a weekly study schedule.


Once


prepared,



follow


the


sam


e


pattern


every week with


m


inor


adjustm


ents.


Sunday


is


an


excellent


day


to


make


up


your


schedule for the following week. Write in your class schedule first. Add your work hours, if any. Then write in


the hours each day you feel you m


ust allocate for study. Keep it sim


ple.



Message 4. Be realistic.


When


you


plan


tim


e


for


these


things,


be


realistic.


Don't


underestim


ate.


Overestim


ate,


if


possible, so


that em


ergencies thatarise don't hang you up. Otherwise your entire routine m


ay get


thrown off balance while


you devote night and day to crash efforts. Message


5.


Make study tim


e fit the course.


How m


uch study tim


e you schedule for each classroom


hour depends on tour factors:(l) your ability, (2)


the difficulty of the class, (3) the grades you hope to achieve, and (4) how well you use your study tim


e. One


thing, however, is certain: you should schedule a m


inim


um of one hour of study for each classroom


hour. In


many cases, m


ore will be required.


Message 6. Keep your schedule flexible.


A good schedule m


ust have a little give so that special projects can be taken care of properly. Think


out and prepare your schedule each week and do not becom


e a slave to an inflexible pattern. Adjust it as y


ou


deem


necessary.


Message 7. Study first ?fun later.


You


will


enjoy


your


fun


tim


e


m


ore


after


you


have


com


pleted


your


study


responsibilities.


So,


where


possible, schedule your study hours in advance of fun activities. This is a sound principle to follow, s


o keep it


in m


ind as you prepare your first schedule.


Message S. Study som


e each class day.


Som


e concentrated study each day is better than


m


any study hours one day and nothing the next. As


you work out your individual schedule, attempt to include a


m


inim


u


m of


two study hours each day. This will


not only keep the study habit alive but also keep you up to date on your class assignm


ents and projects.


Few


beginning


freshm


en


can


control


their


time


effectively


without


a


written


schedule,


so


why


kid


yourself into


thinking you don't need one? You do. Later on, when you have had


more experience and you


have the tim


e


-control habit, you


may be able to operate without it. Of course the schedule is only the


first


step. Once you have it prepared, you m


ust stick with it and follow it faithfully. You m


ust push away the m


any


temptations that are always present or your schedule is useless. Your schedule will give you control only if you


make it work.

08-A. Jet Lag: Prevention and Cure


The problem


of Jet Lag is one every international traveller com


es across at som


e time. But do you have


to suffer? Understand what it is, and how a careful diet can m


inimize its worst effects, and your flights will be


less stressful.


The effects of rapid travel on the body are actually far more disturbing than we realize. Jet Lag is not a


psychological consequence of having to readjust to a different


tim


e zone. It is due to changes in the body's


physiological regulatory m


echanism


s, specifically the horm


onal system


s, in a different environm


ent.



Confused?


So


was


John


Foster


Dulles,


the


Am


erican


Secretary


of


State,


when


he


flew


to


Egypt


to


conduct negotiations on the Aswan Dam


. He later blamed his poor judgem


ent on Jet Lag.



The effects can be used to advantage,


too. President Johnson once conducted an


im


portant


m


eeting


in Guam and kept the entire proceedings at Washington DC time. The White House working personnel were as


fresh


as


paint,


while


the


locals,


in


this


case, were


jet-lagged.


Essentially,


they


had


been


instantaneously


transported to Am


erica.


Now that we understand what Jet Lag is, we can go som


e way to overcom


ing it. A great number of the


body's events are scheduled to occur at a certain time of day. Naturally these have to be regulated, and there


are two regulatory system


s which interact.


One


tim


ing


system


com


es


from


the


evidence


of


our


senses


and


stom


achs,


and


the


periodicity


we


experience when living in a particular tim


e zone. The other belongs in our internal clocks (the m


ajor one of


which m


ay be physically located in a part of the brain called the suprachiasm


atic nucleus) which, left alone,


would tie the body to a


25 hour


-- yes,


25


-- rhythm. Normally the two tim


ers are in step, and the external


cues tend to regularise the internal clocks to the m


ore convenient 24 hour period.



If, however, you m


ove the whole body to a tim


e zone which is four hours different, the two clocks will


be out of step, like two alarm


clocks which are norm


ally set together, but which have been reset a few hours


apart.


Whereas the two clocks would norm


ally sound their alarm


s


together, now they ring at different


times.


Sim


ilarly, the body can he set for evening while the sun is rising.


In tim


e


the physiological system


will reset itself, but it


does take tim


e. One easily m


onitored rhythm


is


palm



sweating.


A


m


an


flown


to


a


tim


e


zone


different


by


10


hours will


take


eight


days


to


readjust


his


palm


sweat. Blood pressure, which is also rhythm


ical, takes four days to readjust.


One reason for this discrepancy is that


different bodily events are controlled by different


factors. T


he


horm


one cortisol, which controls salt and water excretion, is m


ade in the


m


orning, wherever the body is. But


the


growth


horm


one


is


released


during


sleep,


whenever


in


the


day


that


sleep


occurs.


Norm


ally


these


two


horm


ones are separated by seven or eight


hours, but if the body arrives at a destination in the early m


orning


(local) and goes to sleep as soon as possible, the two horm


ones will be released sim


ultaneously.


What can we do about it? It is not feasible to wait four days until the body is used to th


e new tim


e zone.



Fortunately there is a short cut. It relies on two things


--


the power of the stom


ach to regulate the


tim


ing of


other events, and the pharm


acological actions of coffee.


The basic assumptions are:


Coffee


delays


the


body


clock


in


the


m


orning,


and


advances it


at


night.


Coffee


at


mid-afternoon


is


neutral.


Protein in m


eals stim


ulates wakefulness, while carbohydrates prom


ote sleep.


Putting food into an empty stom


ach helps synchronize the body clock.

08-B. Coetrolling Your Concentration


CONCENTRATION IS CENTERINC YOUR ATTENTION


Psychologically defined, concentration is the process of centering one's attention over a period of time.


In practical application, however, concentration is not as sim


ple to deal successfully with as the definition m


ay


im


ply. For this reason, it is helpful to keep the following points in m


ind.



Your attention span varies


Even with


the


greatest


effort,


oar


span


of


attention


fluctuates.


You can


dem


onstrate


for


yourself


this


fluctuation of attention.


In a quiet room, place a watch so that it can just scarcely be heard. Listen carefully


and notice how the ticking increases in apparent intensity, fades to a point where it cannot be heard, and then


increases again. This phenom


enon reveals how our span of attention fluctuates, for the intensity of the ticking


i s actually constant.


You pay attention to one thing at m


tim


e


Evidence to date indicates that you attend to one idea at a tim


e. It is possible for your attention to shift


so rapidly that it seem


s that you attend to several concepts at once. But apparently this is only an illusion. In


high concentration the shift from the focus of attention is of short duration and relatively infrequent.



An illustration of periods of high, moderate, and low attention



High attention has long periods of attending and short distraction periods. In low attention the periods


of


attending


are


short


and


the


distraction


periods


long.


In


moderate


attention


there


is


a


m


ixture


of


the


extrem


es.


Thus


it


is


easy


to


see


that


it


is


highly


unlikely


that


the


student


who


has


m


ost


of


his


attention


centered on fancying at large will be able to recall even the m


ajor points of a lecture.


Lack


of


concentration


is


a


sym


ptom,


not


the


cause,


of


difficulty.


When


a


student


says




can't



concentrate


to the


task at hand because


m


y distractors are too


strong.


DISTRACTORS ARE OF TWO SORTS --PSYCHOLOGICAL AND PHYSICAL


A distractor is anything which causes attention to vary from a central focal point. In the study situation


distractors m


ay be thought of as either psychological or physical in nature. Both types of distractors m


ust be


understood before the student can attempt to rem


edy his lack of concentration.



Em


otions are the m


ost powerful distractors


The angry m


an forgets the pain of injury the fearful man finds it difficult to enjoy pleasure and the tense


or


anxious


person


m


ay


react


violently


to


the


sm


allest


of


matters.


In


the


student's


life


there


are


m


any


psychological pressures and tensions which block effective productivity. The


fears about


making


the grade,


the doubts of the friendliness of a friend’


s behaviour and the pressures of lim


ited finances


-- these are only


a few of the em


otional forces which affect the student.


Em


otional reaction varies greatly from person to person. So


m


e persons gain goal and direction from


their tensions and actually do better because of them. Others fall apart under pressure, while a fewpeople do


well despite the pressure.


Physical distractors are always present and rarely understood



Our environm


ent is


m


uch


m


ore important


to how we feel and react than we often think. Particularly is


this


true


of


the


effect


of


physical


distractors


on


m


ental


tasks.


One


research


report


has


shown


that


com


prehension and retention of reading were decreased when students lis


tened to lively m


usic. However, rate



17


of reading was not affected, so that many students were not aware that they were affected by the background


distractor. Another study found that the ability to recall accurately was affected by distracting conditions. M


ost


of


the evidence indicates that noise affects adversely higher m


ental


task output. Still, the effect of distractors


is seldom


fully appreciated by students.


ROUTINE AND REASONING TASKS ARE AFFECTED DIFFERENTLY BY DISTRACTORS


Many routine tasks can be perform


ed with distraction in the background with little or no adverse effect


on output. Most students have found this fact to be true from


their own experience. They m


ay have had high


school


hom


ework which was


drill


or


m


erely


copying


assignm


ents.


It


was


pos


sible


to


do such work with


the


latest recordings or the television set playing in the background. In tim


e such students began to feel certain


that


they could do all work -- routine or problem-solving -- in


the sate


m


anner. The evidence indicates the


contrary conclusion.


EXCEPTIONS MAY MISLEAD YOU


Typically when


students


are


faced


with


the


evidence


on


distractors


the


argum


ent


is


given


that


their


cousin,


friend,


or


classm


ate


can


study


in



Central


Station.”



And


he


makes



A's


too!


There


is


evidence, of course, that


m


otivation plays an im


portant role in overcom


ing the effects of distractors and that


there are considerable differences in individual spans of attention. Either of


these factors could account


for


som


e individuals being able to do well using inefficient


m


ethods. The


fact


that som


e exceptional people do


well under adverse conditions scarcely justifies your assum


ing that you are exceptional in the sam


e


manner.


Your chances of success are higher if you avoid the distractors which are known to hi


nder the typical student.


09-A. Aging in European Countries


We have to realise how old, how very old, we are. Nations are classified as


per cent or more of


their people aged 65 or above, and by about


1970 every one of the advanced c


ountries


had becom


e like this. Of the really ancient societies, with over 13 per cent above 65, all are in Northwestern


Europe. At the beginning of the l980's East Germ


any had 15.6 per cent, Austria, Sweden, West Germ


any and


France


had


13.4


per


cent


or


above,


and


England


and


Wales


13.3


per


cent.


Scotland


had


12.3


per


cent.


Northern Ireland 10.8 per cent and


the United States 9.9 per cent. We know that we are getting even older.


and that


the nearer a society approxim


ates to zero population growth, the. older its population is likely to be


-- at least, for any future that concerns us now.


To


these


now


fam


iliar


facts


a


number


of


further


facts


may


be


added,


som


e


of


them



only


recently


recognised. There is the apparent paradox that


the effective cause of the high


proportion of the old is births


rather than deaths. There is the econom


ic principle that the dependency ratio ?the degree to which those who


cannot earn depend for a living on those who can ?is m


ore advantageous in older societies like ours than in


the younger societies of


the developing world, because lots of dependent babies are m


ore of a liability


than


numbers


of


the


inactive


aged.


There


is


the


appreciation


of


the


salient


historical


truth


that


the


aging


of


advanced societies has been a sudden change.


If



is a rapid resettlem


ent of the social structure, and if the age composition of the society


counts as a very important aspect of that social structure, then there has been a social revolution



in European and particularly Western European society within the lifetime of everyone over 50. Taken


together,


these


things


have


im


plications


which


are


only


beginning


to


be


acknowledged.


These


facts


and


circum


stances were well to the fore earlier this year at a world gathering about aging as a challenge to


science


and to policy, held at Vichy in France.
