HI, STUDENTS! I hope you have beenmaking notes on the lessons we havedone so far. I will continue to look at

other functions and the importance of the humanresources office.

STAFF WELFARE

Staff welfare is concerned with themaintenance of safe working conditions and theprovision of services for employees. Theseservices include pension scheme,superannuation schemes, medical scheme andsafety regulations.

PROMOTION, TRANSFER,

LAYOFF AND DISMISSAL

As organisations change, they have differentlabour requirements. If a firm is expanding, newjobs are created. On the other hand, if thevolume of work is reduced, the workforcedeclines. These factors usually influencepromotion, transfer, layoff and dismissal.

DISCIPLINARY PROCEDURES

It is the employees’ responsibility tofamiliarise themselves with the organisation’srules and regulations. Organisations oftenprovide employees with a staff handbook, codeof regulations, or other written documentindicating the company’s disciplinaryprocedures.

This department, at times, may find itnecessary to discipline employees on mattersrelating to poor performance, absence or notbeing punctual, gross misconduct, harassment,and misuse of the organisation’s facilities.

STATUTORY PROVISIONS FOR

EMPLOYEE PROTECTION

There are statutory provisions for employeeprotection. Such provisions are legislated andoutline such protection conditions as:

� Employee’s leave rights.� Public holidays leave/pay.� Sick leave.� National minimum wage rate.� Maximum work hours.

DUTIES AND RESPONSIBILITIES

OF A CLERK IN A HUMAN

RESOURCES OFFICE

The clerk in this office usually carries outduties under the supervision of the humanresources manager/officer. Very strictconfidentiality should be observed by thisperson in dealing with personnel matters. Theduties include:

� Writing routine letters, e.g., a letter inresponse to a request for information on avacancy; a letter inviting an applicant to aninterview; a letter to successful applicant.

� Arranging meetings for interviews.� Maintaining files and records, including

confidential records.� Sorting various forms, including

application, appraisal, etc.� Providing information regarding job

vacancies, leave, insurance, etc.

CONTRACTS OF EMPLOYMENT

A contract of employment is a documentwhich gives the employee certain particularspertaining to the conditions of the service. It

usually indicates:� Date of commencement.� Remuneration.� Times of payment.� Hours of work.� Length of holidays.� Welfare services and conditions.� Name of department in which employee

will be located.� Length of notice to be given by employer

and employee for termination of employment.

SERVICE RECORD

A service record indicates the date of theemployee’s first appointment to the particularorganisation, the position held, and the length oftime served in each post.

LEAVE

Leave may be granted with pay or without pay.The different categories of leave include studyleave, vacation leave, sick leave, special leave,compassionate leave, maternity leave, and no-pay leave. Again, I am going to require of you to

make notes on the different categories of leave.

PERSONAL HISTORY

This is usually recorded from the employee’srésumé. When the human resources officereceives additional information pertaining toqualifications, training, promotion, marriage,change of address, etc, these details are addedto the employee’s personal history.

APPRAISAL FORM

An employee appraisal form is a record ofperformance evaluation. The appraisal formallows organisations to compare employeesusing the same criteria and becomes part ofeach employee’s personal file. The completion ofthe employee appraisal form must be bothimpersonal and impartial.

See you next week.

GREETINGS TO everyone. This is our lastlesson on this section of the syllabus.Next week, I will present a test so that you

can have an idea of how much you haveunderstood and learnt the information that waspresented to you over the last few weeks.

You will remember that one of the topics weconsidered was the reasons people save and welooked at the various methods of saving. Now,we are going to cover the link between savingsand investment.

Individuals, businesses and governmentssave. To save means to refrain fromconsumption; that is, not spending a part or allof one’s income. The greater the saving, the lessthe demand for goods and services. Whenindividuals, businesses and governments save,it makes possible the accumulation of funds forinvestment purposes. This means that one of themost important determinants of investment isthe level of accumulated savings.

Since individuals, firms and the governmentrequire investment, the funds that are availablemust be shared among the three. Therefore,there will be competition for investment funds.

Investment refers to using money to producecapital goods. Capital goods are goods that arenot consumed for their own sake, but are usedto produce other goods and services. Examplesof capital goods are plant, machinery,equipment, tools and partly finished goods,anything that is used to produce further capitaland consumer goods and services.

There are a number of factors that affect thelevel of investment within a firm or within acountry. Included are the following factors:

� The level of savings.� The rate of interest on loans.� The level of confidence in the future state

of the economy that businessmen have.� The short-term and long-term goals of the

business/country.

� Political stability or instability.� The expectations of investors.� Rules and regulations of government.� Whether suppliers are able or not to meet

the orders of investors.� The marginal efficiency of capital.� The level of economic activity in the

economy.

See if you are able to link the factors abovewith the level of investment.

Governments play an important role indetermining the level of savings and investment.If they increase the rate of interest on deposits,

the level of saving would be expected to rise andmore investment is likely to take place. However,if borrowers’ interest is increased, borrowers willbe expected to decrease their borrowing and, inturn, their investments. Therefore, the increasedsaving has only made funds available forinvestments; it does not guarantee thatinvestment will take place.

Being the largest buyer of capital goods,governments are the largest and most importantinvestors in any country. Since this is so, theyhave the greatest need for investment funds. Ifthere is a shortage of these funds, they may haveto borrow from within the country or from

outside the country.

That’s it for this lesson. Do have yourselves awonderful week. Remember to study the entireSection 7: Business Finance for the test nextweek. Studying involves not just the lessonnotes I have presented, but also reading materialrelated to the topics. In the following weeks, wewill be going through Section 8: Role ofGovernment in an Economy. Bye for now.

METAL IONS can be differentiated using two different methods. In the first method, metal ionscan be identified based on the colour of the flame produced in a Bunsen flame. This methodis called the flame test. The steps are outlined below. A clean flame test rod or nichrome

wire is used to take a sample of the metal compound, usually a solid. The metal ion is identified byits characteristic flame colour.

In the second method, metallic ions (cations) are identified based on the colour and solubility ofthe hydroxides formed from their reaction with aqueous ammonia and sodium hydroxide. Metal ionsreact with hydroxide ions (OH-) forming metal hydroxides as insoluble solids or precipitates. Thesolubility of the precipitates in excess of the hydroxide solution is noted. Different metal ions givedifferent colour precipitates.

Fe2+ produces a dirty green precipitate, which is insoluble in excess NH3 (aq) and NaOH (aq).Fe3+ produces a rusty brown precipitate, which is insoluble in excess aq NH3 and NaOH.Cu2+ forms a blue precipitate, which is insoluble in excess aq NaOH, but soluble in excess aq NH3.

These cations can clearly be identified based on their colours alone.

From the table shown below, four cations produce white precipitates when reacted withhydroxides. To distinguish between these ions, the solubility of the precipitates must be noted.

Al3+ and Pb2+ both form white precipitates when reacted with aq NaOH and NH3. In aq NaOH, theprecipitates are soluble in excess while in aq NH3, they are insoluble in excess. As can be seen, Al3+

and Pb2+ give the same results so, to differentiate between them, other reactions must be taken intoconsideration. Pb2+ will also form precipitates with I-, Cl- and SO4

2- ions (PbI2 (yellow), PbCl2 (white),and PbSO4 (white), while Al3+ will not.

Two other cations form white precipitates. Zn2+ forms a white precipitate, which is soluble both inexcess aq NaOH and NH3. Ca2+ forms a white precipitate, which is insoluble in excess NaOH, butdoes not form a precipitate when treated with ammonia. The NH4

+ ion can be identified based on theevolution of ammonia (NH3) gas when warmed with aq NaOH.

WELL, HELLO there! How are you this week? I don’t knowwhy I am asking because at this point in time, you couldnot be anything else but good! You have been keeping up

with your work and all your SBAs are at a point where they justneed some editing, so life must be good! Continue to work tokeep it good! Here is something I want you to remember always:

“A bad attitude can literally block love, blessings and destinyfrom finding you. Don’t be the reason you don’t succeed.”

Last week, we began to look at the feeding relationships oforganisms in the environment and we ended our lesson at thedefinition of the food web; you need to learn this definitionbecause you may be asked to reproduce it. This week we will belooking at how the food web is constructed. One important pointthat must always be remembered when constructing a food web isthe direction in which the arrows point. The arrows must alwayspoint from the producer (the plant) to the consumer (the animal).Having them point in any other direction will not gain you anymarks for your efforts.

Look carefully at the drawing of the food web. Notice thefollowing:

� All the arrows point to the organism that is feeding, i.e.,away from the organism that is providing the food.

� The organism at the base of the web on the first line is theplant, i.e., the cherry tree, oak tree, algae. This line representstrophic level No.1; hence, these plants are the producers.

� All the organisms that feed on the producer are placed onthe line above the producer. The next line above representstrophic level No.2 and the organisms placed there are theherbivores or primary consumers. From food web No.1, these are,the caterpillar, the aphid, the stink bug and the moth. Food webNo.2: aphids, caterpillar, wood beetle, snail. Food web No.3:tadpole, water beetle, snail.

� The organisms that feed on the primary consumers areplaced in a line above the primary consumers. This linerepresents trophic level No.3. These organisms are the secondaryconsumers. Again, from food web No.1, these are: the ladybird

beetles; from food web No.2: ladybird, blackbird and thrush; fromfood web No.3: frog and small fish.

� The organisms feeding on the secondary consumers areplaced in a line above the secondary consumers. This linerepresents trophic level No.4 and these organisms are the tertiaryconsumers. These are the bird and the spider from food webNo.1, the hawk and from food web No.3, the kingfisher.

� Some organisms can be classified as both secondary andtertiary consumers; for example, the bird is a secondaryconsumer when it is feeding on the moth, and a tertiary consumerwhen it is feeding on the ladybird beetle.

You should also be able to extract several food chains from thisfood web. Let us do this now.

� Cherry tree – aphid – ladybird beetle - spider� Cherry tree – stink bug – ladybird beetle – bird� Cherry tree - moth – birdLet us see if we can now put our newly gained knowledge to

use.Use the animals listed in the following table to create a food

web.

ORGANISM FOOD EATEN

Crab Decaying plant matterGuppy (fish) Mosquito larvae, tadpolesWater bird Guppy, frog, crabWater snail Algae, water weedMosquito larvae Moss, decaying plant matterWater weed Makes own foodFrog Dragonfly, mosquito larvaeTadpoles Water weed

What is the first thing that we need to do? Did you answer,Identify the producer/producers? I hope you did, because that iswhat we must do! The producer has to be first identified, since itforms the base of the food web.

Let us take a look at the organisms that are included in thetable. Notice that the only organism that could meet therequirements of the producer is the water weed, since it makes itsown food. Notice, also, that there is mention of other plantmaterial in the table. Some of the organisms feed on decayingplant material and the mosquito larvae also feed on moss; theseare also classified as producers. The next level belongs to theprimary consumers, or the herbivores. Remember these are theorganisms that feed on the plant material. From the table, we canidentify that tadpoles, water snail, crab and mosquito larvae arethe herbivores. All of the other organisms in the table arecarnivores. These are the frog, the guppy, water bird. Althoughthey are all carnivores, this does not mean that they are allsecondary consumers. Notice that the water bird feeds on theguppy, which feeds on the tadpole. This makes the guppy asecondary consumer and the water bird a tertiary consumer. Wasthat confusing? Let us put it in the form of a food chain to make itsimpler.

� Water weed – tadpole – guppy – water bird. There you go,Do you see it now?

TOPIC

Illustrate weather systems using isobars andrelevant symbols.

FOCUS QUESTIONS

� What is weather?� What affects weather?� What are the different weather systems?� What are station models?� What are weather symbols plotted on?

Weather is the state of the atmosphere at agiven time and place. Our weather is affected bya number of factors, including latitude, relief,aspect and distance from the sea.

� Latitude – Places closer to the equator areusually warmer, and places nearer to the NorthPole and South Pole are colder.

� Relief – Places located on flat, low-lyingland are warmer and places higher up, i.e.,mountains are colder and wetter.

� Aspect – Places which are south-facingare warmer and places which are north-facingare colder.

� Distance from the sea – Places nearer tothe sea are mild and wet, and places further fromthe sea are drier, but temperatures are moreextreme.

DEPRESSIONS

WEATHER FRONTS

A depression is an area of low pressure whichmoves from west to east in the northernhemisphere.

Low-pressure systems can be identified froma synoptic chart due to:

� Cold fronts� Warm fronts� Possible occluded fronts.� Tightly packed isobars.� Isobars showing pressure decreasing

towards the centre from about 1004mb.

WARM FRONT

In a low-pressure system, the warm front isthe first to pass over. This occurs when warm airmeets cold air and the warm air rises above it.Warm fronts bring steady, continuous rain.

COLD FRONT

The next front to pass over is the cold front.This occurs when cold air meets warm air. Thecold air pushes the warm air upwards. Coldfronts bring heavy rain showers.

OCCLUDED FRONT

When the cold front catches up with the warmfront, the result is an occluded front. Occludedfronts bring sudden downpours of heavy rain.

All three fronts are associated with rain.

DEPRESSION CHARACTERISTICS

Where isobars are close together, the wind isgreatest. This is because of a rapid change in airpressure.

� Wind – Winds blow anticlockwise in adepression and wind blows along the isobars.You can work out the wind direction byfollowing the isobars in an anticlockwisedirection.

� Wet – Where warm air meets cold air, thewarm air is pushed upwards where it cools,condenses and precipitates (usually as rain). Afront is a band of cloud and clouds bring rain.

� Temperature – In general, the warm sectorbehind the warm front brings warmertemperatures, and the cold sector behind thecold front brings cooler temperatures.

As a depression passes over, the followingchanges occur:

The changes are explained below.

ANTICYCLONES

An anticyclone is an area of high pressurewhich brings long periods of settled weather.Warm air is sinking, which means clouds do notform. High-pressure systems can be identifiedfrom a synoptic chart due to:

� Widely spaced isobars.� No fronts/clouds.� Isobars showing pressure increasing

outwards from the centre and above 1008mb.

HIGH-PRESSURE CHARACTERISTICS

Isobars are spread far apart, bringing gentle

winds. This is caused by a very gradual changein air pressure. Due to these gentle winds, thesesystems can remain in place for several days.

� Wind – Winds blow clockwise in highpressure and wind blows along the isobars.Wind blows gently when isobars are widelyspaced.

� Temperature – In summer, skies are clearwith little cloud and temperatures are high, whilein winter, skies are also clear with little cloud,but temperatures are cold and there is alikelihood of frost and fog.

The main way meteorologists draw diagramsof the weather is by using something called thestation model.

The station model is a symbolic drawingshowing the current weather at a particularlocation.

� It’s called the station model because itshows the weather measured at a particularweather station, or an area where the weather ismeasured.

� It lets meteorologists see a lot ofinformation in a very small space.

� The symbols and numbers found there arethe same across the world and have hardlychanged in 75 years.

Sometimes not all the numbers will beshown, but the position of each number tellswhat it means.

Each station on the station model contains:� A central picture that represents the wind

speed and direction.� A circle or dart to represent cloud cover.� A symbol to the left of that to represent the

current weather.� A symbol above to represent the type of

clouds.� Then various numbers in particular

positions around it, including temperature andair pressure.

A weather symbol is plotted if, at the time ofobservation, there is either precipitationoccurring or a condition causing reducedvisibility.

In the centre of the station model is a symbolor picture that represents two things:

� The cloud cover.

� The wind speed.

The central circle represents the cloud cover.A black circle means the sky is completelyovercast and cloudy, and a white or empty circlemeans that the sky is completely clear of clouds.

The amount of black shown in the circle tellsthe fraction of the sky that is covered. It’s likecutting up a pie to represent one half or onequarter.

Weather symbols are plotted on a synopticchart used for weather forecasting, and show theposition of weather stations collectinginformation about the weather and details of thevarious weather elements.

The position of a meteorological station ismarked by a small circle.

The weather report for each station is thenplotted in and around the circle.

� Elements like temperature and pressure areentered as plain figures.

� Others, like the occurrence of rain, snow,cloud and fog, are plotted as internationallyagreed symbols.

EXAMPLE

Cloud cover at a particular time is:� Indicated by filling in certain portions of

the circle.� The greater the fill, the more the cloud

cover, measured in eighths or oktas.

Wind direction is represented by an arrowpointing in the direction from where the wind iscoming.

� The wind speed is denoted by ‘feathers’ onthe wind arrow; a short feather indicating 5knots, a larger one 10 knots, a long and shortone 15 knots, and so on.

Temperature is measured in degrees Celsiusto the nearest whole degree.

Pressure at a station is standardised to sea-level pressure measured in millibars.

THE END OF CHATTEL SLAVERY IN THE

BRITISH CARIBBEAN

HI, GUYS. This week’s lesson focuses onthe factors that accounted for the end ofthe system of chattel slavery in the British

Caribbean.

OBJECTIVES

At the end of the lesson you should be ableto:

1. Discuss four causes of emancipation in theBritish Caribbean.

1. AGITATION BY THE

ENSLAVED POPULATION

The action of the enslaved population alsoproved integral in the dismantling of chattelslavery in the British Caribbean. Insurrectionarymethods of resistance, especially revolts,demonstrated the desire of the enslaved Africansto have liberty and regain their personhood.Several revolts in the British Caribbean includedTacky’s Rebellion, Bussa’s Revolt and theBerbice Rebellion. The last major slave revoltbefore emancipation was the Sam SharpeRebellion or Christmas Rebellion. Sam Sharpe,a slave and Baptist deacon, believed that theBritish Parliament would emancipate the slavessoon and that the planters would try to find waysof keeping their unpaid force labour. Sharpe wasa literate slave and oftentimes read his master’snewspaper. He led a strike soon after theChristmas holidays as slaves decided theywould not work unless they were paid wages.The strikes that began relatively quiet wouldlater erupt as cane fields and estates were burntand other property destroyed. Over 400 slaveswere killed and 100, including Sharpe, wereexecuted. The Christmas Rebellion provedsymbolic as it demonstrated the thrust byenslaved Africans to continue their fight forliberty. The rebellion was also the largest andmost wide-scale of slave revolts in the BritishCaribbean.

2. ECONOMIC MOTIVE –

THE EAST INDIA INTEREST

The growth of the British Empire in India ledto the growth of a powerful ‘East India Interest’ inBritish politics. These individuals were primarilymerchants and industrialists who objected to thefavoured treatment given to the West Indian(British Caribbean) Interest for two reasons. Onewas that goods such as tea and cotton producedin India were done with the use of free labourinstead of the slave labour used in the BritishCaribbean. The other was that protectionism wasstill being practised in relation to the Caribbean– giving their sugar preferential treatment in theBritish market. The East India Interest arguedagainst slave labour, describing it is anexpensive and inefficient use of labour. Theyalso argued that Britain, as a part of herindustrial development, should move from asystem of protectionism to one of free trade.With several prominent figures of the East IndiaInterest gaining parliamentary seats in the 1832elections, the process of defeating the WestIndia Interest and chattel slavery became lessarduous.

3. THE FAILURE OF THE

AMELIORATION SYSTEM

This system was an attempt to improve theconditions faced by the enslaved Africans in theBritish Caribbean and should have been enactedby local assemblies. The system came into effectin 1823. The proposals included the following:

� A record of all lashes should be kept andpunishment should be delayed for 24 hours.

� There should be the establishment of slavesavings bank.

� Prohibition of the separation of slavefamilies.

� Slaves should not be sold in payment ofdebt.

� Female slaves should not be whipped, andthe overseers and drivers should not carry awhip in the fields.

The measures were strongly resisted byplanters in Jamaica, Barbados, St Vincent andDominica. Several assemblies only passed a few

of the least important amelioration proposals. Theamelioration proposals failed, but they providedone of the major impetus for the abolition ofchattel slavery. With the failure of the plantocracyto implement many of these ameliorationproposals, it became evident that what wasneeded was freedom for the enslaved Africans.

4. ROLE OF THE HUMANITARIANS

Several groups of humanitarians worked hardto improve the conditions of slaves and,ultimately, to lobby for the end of slavery. Theytried to convince the British Parliament and thecitizenry of the immorality of slavery. They heldmock slave auctions; displayed exhibits of itemsused to punish slaves; as well as distributedpamphlets describing the horrors of slavery.These actions were hoped to arouse the moralconscience of the British citizenry. Prominenthumanitarians included Granville Sharp, WilliamWilberforce and Thomas Clarkson. These menwere a part of a group called the ‘Saints’ or‘Clapham Sect.’ Other groups involved in theabolitionist cause were the Baptists, Quakersand Methodists.

5. MANSFIELD JUDGMENT

This judgemnt provided a watershed momentfor humanitarians as it brought into sharp focusthe discussion on whether or not slavery waslegal in England. In 1772, Granville Sharp, aleading abolitionist, took the case of JamesSomerset to the English courts. Somerset, anenslaved man from Jamaica, was taken toEngland by his owner. He was turned out by hismaster but later, he [his master] would makeattempts to regain his ‘property’. Somerset’scase went before the chief justice, LordMansfield, on February 7, 1772. After carefuldeliberations, Mansfield provided a ruling inJune of that year. Lord Mansfield ruled that hisstudy of the laws of England found that thepower of a master to use force on a slave was‘unknown to the laws of England’. What was theimplication of such a ruling in England?

OBJECTIVE

Describe the structure of government –principle of separation of powers.

THE SEPARATION of powers doctrineensures that the balance of power ismaintained within each arm of the state. As

it relates to Jamaica, separation of powers existsas there are safeguards put in place to ensurethat no institution overpowers the other or usurpits function. The statement ‘separation ofpowers’ describes the distribution of powerbetween different branches of government. Inmost Caribbean countries, this is between theexecutive, judicial and legislativeresponsibilities of a government which, to alarge extent, are separate and distinct bodies. Itis widely believed that a separation of powerwould prevent the abuse of power by anindividual or any single governmental body.

The system of governance in Jamaica is aconstitutional monarchy under which the queen,represented by a governor general, is head ofstate.

Under the constitutional monarchy, there arethree arms of government:

� The executive� The legislature� The judiciary

The Jamaican Constitution was drafted toreflect the British sociopolitical model, known asthe Westminster-Whitehall system ofgovernment. This model guarantees thatcitizens, through universal adult franchise, havethe right to participate in free and fair elections,and choose the officials that govern the country.

HEAD OF STATE

The governor general is the officialrepresentative of the head of state in Jamaica.This individual has the responsibility to appointthe principal officials responsible for leading theState.

The governor general appoints the primeminister, deputy prime minister, leader of theopposition, members of the Cabinet, the chiefjustice, president of the Court of Appeal,ministers of state, judges of the Court of Appeal,chairs of the Public Services Commissions andthe director of public prosecutions.

The governor general is also solelyresponsible for granting the prerogative ofmercy (pardon) to convicted offenders upon theadvice of the Privy Council. The governorgeneral’s formal assent is required beforeparliamentary bills become enacted into laws.

THE LEGISLATURE

STRUCTURE OF THE LEGISLATIVE

The Parliament of Jamaica is the legislativebranch of the Government of Jamaica. It is abicameral body, composed of an appointedsenate, also known as the Upper House, and anelected House of Representatives, also known asthe Lower house.

The governor general represents the queen inParliament, and his role is a formal one. Once ayear, at the official opening of Parliament, hedelivers the Throne Speech.

The legislature is empowered by theConstitution to amend existing and enact newlaws. This arm is also in control of thegovernment’s finances and guides fiscal policy.The head of state’s role in Parliament, executedthrough the governor general, is to open anddissolve Parliament and grant royal assent tobills passed in the Houses of Parliament.

SENATE

The Senate is a nominated house made up of21 senators in Jamaica. Thirteen senators areappointed by the governor general on the adviceof the prime minister. The other eight areappointed on the advice of the leader of theopposition. Not more than four ministers can beappointed from the Senate, and they may haveportfolio responsibilities. The Senate usuallyfunctions as a review chamber, considering bills

passed by the House of Representatives. TheSenate may also initiate legislation, exceptmoney bills.

HOUSE OF REPRESENTATIVES

The House of Representatives consist of 63members, elected by single-memberconstituencies using the first-past-the-postsystem. The government in power can only existif it has the support of the majority of themembers of the House of Representatives. Mostbills are initiated in the House ofRepresentatives.

THE SPEAKER

The Speaker of the House is formally electedby the members of the House of Representativesfrom among their number, at the first sitting aftereach general election or when there is a vacancy.His job includes keeping other members withinthe rules of the House, and ensuring that therights of the opposition members are protected,and that every member gets a fair hearing.

HOW A BILL BECOMES LAW

A bill is an act of Parliament in draft, and nobill can become law until it is approved by theHouses of Parliament and receives the formalassent of the governor general. Bills may beintroduced in either the House of Representativesor the Senate, but no bill involving finance canbe first introduced in the Senate. After a bill hasbeen introduced in the House, it must passthrough several stages, known as ‘readings’.

FIRST READING

At ‘first reading’, no debate on the bill isallowed. The bill is read by the clerk of thehouse. The bill is ordered to be printed and aday is appointed by the member in charge of thebill for its second reading.

SECOND READING

The bill is debated fully at the ‘secondreading’. At the end of the debate, a vote istaken.

COMMITTEE STAGE

If the bill passes its second reading, it moveson to the ‘committee stage’. This committeecomprises the whole House, unless the Houserefers the bill to a select committee. At thispoint, the bill is considered in very close detail.Every clause is carefully examined, andamendments to the bill may then be moved andvoted upon. A bill may not be rejected duringthe committee stage.

REPORT STAGE

After the committee stage, there is the ‘reportstage’, when the Speaker reports what hashappened to the bill in committee, whether therehave been amendments or not.

THIRD READING

No amendments of a substantial nature maybe made at the ‘third reading’; a bill may beaccepted or rejected by means of a vote. When abill is first passed by the House ofRepresentatives, it is sent to the Senate, where itgoes through the same procedure as one whichoriginated in the Lower House.

If the Senate disagrees with any aspect of thebill and makes an amendment, the bill is sentback to the House of Representatives forconsideration. If the House disagrees with theSenate’s amendment, it informs the Senate,which is then asked to reconsider the bill. Whenan agreement is reached and the bill has beenpassed through all its stages in both Houses, itrequires only the royal assent to make it law. Theroyal assent is given by the governor general.

THE ROLE OF THE OPPOSITION

The Opposition’s main role is to question theGovernment of the day and hold themaccountable. Opportunities for scrutinising thepolicies and administration of the Governmentare provided in yearly Budget debates, debateson legislation, notices of motion and noconfidence motions. The Opposition utilises themedia to reach the electorate with its views and

HELLO, STUDENTS! How has the yearbeen going? I hope you have completedyour SBAs and are doing all you can to

ensure the best performance in your externalexamination.

For this lesson, we will begin our focus onstory writing.

Your ability to write an interesting story isassessed in Section C of Paper 02. You arerequired to write a story, using 400-450 words,based on either a picture or a sentence prompt.All this is worth 25 marks.

Effective story writing requires you to beimaginative, creative and well-read. It is an artthat is strengthened by practice and frequentreading of a variety of narratives. Many of ushave untold stories within us. Thus, it isimportant that we seek to develop theappropriate means to tell them.

A superior story has the elements of the shortstory and manipulates them effectively innarrating a series of events. What, then, are theelements of a story?

ELEMENTS OF THE SHORT STORY

CHARACTERS

This is a person – or even animal – that takespart in the action of the story. For CXC, it isrecommended that you have no more than threecharacters in your story.

A story usually has a protagonist (maincharacter) and an antagonist (character whoopposes the main character).

SETTING

This is the time or place in which the eventsin the story take place. For example, the storymight take place at a basketball game, at aperson’s house or in a church. It is encouragedthat you limit the number of settings, since thestory is a short one. In fact, you are challenged

to limit the events to one setting. This way, itshould be easier to control your story.

POINT OF VIEW

This is the perspective from which the story istold. Is it a first-person (being told through theeyes of a character from a first-handperspective), omniscient (having theperspectives of different characters) or third-person (having the perspective of one maincharacter) narrative? Pay attention to thesentence prompts that are given so they canguide the point of view you should select. Also,remember that if you mix the points of view, youwill be penalised.

PLOT

The plot is how the writer arranges events todevelop his basic idea. It is a planned sequenceof events that has a beginning, middle and end.There are five aspects of the plot:

� IInnttrroodduuccttiioonn:: This is the beginning of thestory where the setting and the characters arerevealed.

� RRiissiinngg aaccttiioonn:: This is where the events inthe story start to show evidence of aproblem/complication and a conflict isrecognised.

� CClliimmaaxx:: This is the highest point of interestand the turning point of the story. The readerwonders what will happen next. Will the conflictbe resolved or not? It involvessuspense/tension.

� FFaalllliinngg aaccttiioonn:: The events and theproblems begin to be resolved. The readerknows what has happened next and if theconflict is resolved.

� DDeennoouueemmeenntt:: This is the resolution of thestory or the story’s outcome.

The plot may also include the use of specificnarrative techniques, known as a twist (when thestory ends differently from what is expected), ora flashback (a device in the narrative by whichan event taking place before the present time inthe narrative is inserted into the chronologicalstructure of the work as a means of explainingpresent events). It must be noted that if youemploy the flashback technique, you must returnto the present. You must not end the story in theflashback.

CONFLICT

This is the struggle that occurs betweencharacters or within characters. You have twotypes of conflicts: external (occurring betweentwo characters, between man and theenvironment or man and the society, as well asinternal (struggle within oneself to make a

decision or overcome a problem).

USE OF DIALOGUE

This is the conversation between characters.These are usually indicated by the use ofinverted commas and other punctuation marks.

EXAMPLES

Peter demanded, “Are you telling the truth?”His wife pursed her lips before she answered.

“Yes, I am and if you don’t believe I will neverforgive you.”

One important rule of writing dialoguecorrectly is to give each character a new linewhen he or she begins to speak. Therefore, youwould not do this:

“Are you sure that is all you need?” mymother asked. “Yes, I am sure.” “Okay, then. Letus go.”

Here is a better way of writing that dialogue:“Are you sure that is all you need?” my

mother asked.‘Yes, I am sure,” I responded.“Okay then. Let us go.”

Dialogue is also important for severalreasons.

1. It helps in advancing the plot.2. It reveals qualities of characters.3. It contributes to the conflict or

suspense in the story.

Please note that dialogue should notbe used as mere fillers in your stories

but should enhance the events/actions in yourstories.

THEME

This is the central point that the writer istrying to communicate. The story may beabout the consequences of lying or the joys

of hard work.It is important that you familiarise

yourselves with these elements as they formessential parts of the stories you relate.Writing a story successfully in theexamination is determined by your attitudeand your willingness to upgrade yourcreative and imaginative abilities. Thestories that demonstrate competence,suggest superiority and demonstrate

superiority, are usually the ones thatreveal that students have been

BBEERRYYLL CCLLAARRKKEEContributor

LET ME welcome you to this week’s lesson.We are, as promised sometime before theChristmas break, returning to our

exploration of Harper Lee’s TToo KKiillll aaMMoocckkiinnggbbiirrdd. Mayella Ewell is our first subjectof discussion. How do you feel about thischaracter? Please stop a little while and considerthis girl who has had to take on the role ofmothering her siblings and, frighteningly, theunbearably disgusting task of an incestuouspartnership with her father.

We, unfortunately, live in a time where all toooften we learn of cases of child abuse, both hereon our own island and across our world. Theforms of abuse vary and are many timesignored, as in Mayella’s circumstance. Do youthink that the fine, upstanding citizens ofMaycomb were not aware of the abuse in thatfamily? Bob Ewell, the father, was left alone todo whatever he wanted.

... white people wouldn’t have anything to dowith her because she lived among pigs; Negroeswouldn’t have anything to do with her becauseshe was white. She couldn’t live like Mr.Dolphus Raymond, who preferred the companyof Negroes, because she didn’t own a river bankand she wasn’t from a fine old family. Maycombgave them Christmas baskets, welfare moneyand the back of its hand.

Everybody knew that he was a lazy, shiftlessand irresponsible father, but neither church, citygovernment (and there must have been one) northe legal system ‘interfered’. The only personwho tried to do something practical to helpreceived imprisonment and death for his efforts.So, Mayella, a poor, sad, uneducated woman,has a pivotal role in our story. She claims thathaving gone to school for two or three years,she can read as well as her father. Notice thatshe does not say that she can read well, but aswell as her father, which probably means thatneither of them can read well.

Mayella has never been treated with

politeness and courtesy. She has no friends.She, and not her father, is responsible for therunning of the home. Any mother will tell youthat caring for several children is not easy, andthat not having much money makes it hard. ForMayella, it must have been very hard. Do youremember how long it took for her to save themoney for her brothers and sisters to be able tobuy ice cream? Her environment was degradingand she and her family were degraded by thisbut, more than anything or anyone else, it is BobEwell who, through his parental neglect, abuseand belief in a non-existent superiority fed byracism, makes Mayella an outcast and a figureof pity.

Mark you, it appears that if she could haveimproved her circumstances she would havedone so. On the witness stand, Tom Robinsonspoke of her care of the geraniums that she musthave planted in her yard. We learn, too, fromScout, that she seemed to have made the effort,though not completely successfully, to keep herperson clean.

Mayella reveals another side of herself in thewitness box. She cries twice. Why does she doso the first time? Is it because she is truly afraidof Atticus, or is she slyly ensuring that judgeand jury will feel sorry for her? She comesacross as being very lonely but also a real liar.She is not a fool, for when she realises that herevasions and conflicting statements andanswers are exposing her and the truth of whathappened, she shuts her mouth and adamantlyrefuses to say another word. We could draw theconclusion that that was because she was afraidof what her cruel father would do to her, but wemust not ignore the fact that it was Mayella who,by her decision to seduce Tom, creates all ofthis terrible situation.

Her action had been well thought out and wellplanned. Do you remember how long she savedfor the ice cream? She had been scheming for aconsiderable length of time to have a‘relationship’ with Tom. She did not consider theconsequences of her action, particularly for Tomwho was not only a married man, but also a

Negro. She behaved like a small child who seesa toy and will do anything to have it, only tothrow it away after playing with it for a shortperiod. As Atticus says, because she had beencaught and embarrassed by her conduct, shewanted to erase the innocent man who had theboldness, the daring to be sorry for her. Her finalspeech to the court makes it clear that she isrelying on the racist feeling of the white jury tooverlook her obvious guilt and convict the blackman who was, as we would say, ‘out of order’enough to pity her, her a white woman.

She cries then, for the second time, but this isout of anger. Why does she become so angrythat she cries and why does she hate Atticus?These are questions that I am asking you tothink about carefully as we consider this flawedcharacter.

God bless!

NNAATTAALLEEEE AA.. JJOOHHNNSSOONNContributor

GOOD DAY, students. This is lesson 19 in our series oflessons. In this week’s lesson, we will continue to look atproblem-solving and program design.

Before we continue looking at program design, here are thesolutions to the defining diagram questions I gave you in theprevious lesson.

QUESTION 1

QUESTION 2

In the previous lesson, we started looking at how problems aresolved on the computer, and there are certain key terms you willneed to know. We had already examined the terms ‘variable’ and‘constant’.

Now, let us pick up where we left off.

Data types: Variables typically store values of a given type.There are several data types, but we will be focusing primarily onthe following data types: integers, floating point (real), charactersand strings.

� Integers – Used to store whole numbers (whether negativeor positive), for example, 5,-10, etc.

� Floating point/Real – Used to store real or fractional

numbers, for example, 3.1, 22/7 etc.� Characters – Any single character in the ASCII set (a single

character such as a letter of the alphabet or punctuation) forexample, ‘A’, ‘@’, ‘$’, etc.

� String – A collection of characters such as a word, phrase orsentence; for example, Natalee.

� Literals are a special class of data type, and they cover thosevalues that are fixed (even if only temporarily). For example,consider the following output statement:

Print ‘Please enter your name’. The words shown in quotationwould be considered an example of a literal string value.

ALGORITHMS

An algorithm is a sequence of precise instructions or stepsused for solving a problem in a finite amount of time.

The properties of an algorithm are:1. It must be precise (exact).2. It must be unambiguous (in other words it must be clear).3. It must give the correct solution in all cases.4. An algorithm must terminate or eventually end.

THE ALGORITHMIC STRUCTURE

Every algorithm should have the following sections, in thestated order:

HHeeaaddeerr:: Algorithm’s name or title.DDeeccllaarraattiioonn:: A brief description of the algorithm and variables

used. That is, a statement of the purpose as well as declaration ofthe variables.

BBooddyy:: Sequence of steps.TTeerrmmiinnaattoorr:: An end statement.

THE ALGORITHMIC LANGUAGE

When writing algorithms, the language gradually progressesfrom English towards a notation that resembles that of aprogramming language. An intermediate notation calledpseudocode is commonly used to express algorithms. Apseudocode is an imitation of a computer program written usingmathematical notations and English-like statements to describethe logics to solve a problem or carry out a procedure. Thepseudo-code is used as a guide to code the solution to theproblem in a high-level language.

PARTS OF A PSEUDOCODE ALGORITHM

A pseudocode algorithm contains one or more of the followingstatements:

� Input statements� Assignment statements� Output statements� Control structures (sequence, selection, repetition)

DOS AND DON’TS WHEN WRITING PSEUDOCODE

You should do the following: 1. Use the assignment symbol (?) in assignment statements

instead of the equal sign.2. Use the equal sign for conditional statements (if statements)3. Use meaningful variable names4. Use indentation to show the logic and scope of control

structures.

You should not do the following:� Use variable names with a space ex., net income (instead

use an underscore ex., net_income) and starting a variable namewith a symbol or number (this is not allowed).

� Attempt to write the Pascal code before writing thealgorithm. That is, do not execute the program first and then try towrite the algorithm afterwards, based on the program code. Thisis a very bad practice and is essentially a waste of time.

PSUEDOCODE ALGORITHMS

Let us examine the parts of a pseudocode algorithm in moredetails.

INPUT STATEMENTS

The input statement is used to get data from outside thecomputer from a particular input device into a variable formanipulation by the pseudocode. The key words we will use forinput will be ‘input’ or ‘read’. To read data into a variable, you writethe word ‘input’ or ‘read’ followed by the variable name.

This is the way in which it will be written:Read variable_name

The variable_name is the name given to the location where thevalue is to be stored, as you learnt previously. For example, if Iam reading a math score into a variable, my variable name couldbe ‘score’ and the read statement would, therefore, be:

We have come to the end of this lesson. See you next weekwhen, will continue to look at psuedocode algorithms. Remember,if you fail to prepare, you prepare to fail.

THIS WEEK, we will continue to reviewaspects of coordinate geometry. How manyhours were you able to spend last week

reviewing your notes and practising additionalproblems? Do you recall the advice not to waituntil it is too late? We will begin with thesolution to the homework given last week.

HOMEWORK

Given the points X( 2 , -3) and Y( 4 , - 5), findthe values of:

(a) Gradient, m(b) the coordinates of the midpoint, M

SOLUTION

1(a) The gradient of XY = m = y2 - y1 / x2 - x1

Substitutingm = - 5 - -3 /4-2 = - 2/2 = - 1.m = - 1

(b) The midpoint of XY = M = x2 + x1 /2, y2 +y1 /2

SubstitutingM = 4 + 2 /2, - 5 - 3 /2 = 6/2 , - 8/2M = ( 3 , - 4)

2. Given the points X ( 1 , 0) and Y (- 2 , a ), ifthe gradient is 2/3, find a.

SOLUTION

The gradient of XY = m = y2 - y1 / x2 - x1

Substituting,a - 0 /-2 -1 = 2 /3a/-3 = 2/33 a = - 6.a = - 2.

Let us now continue the review of coordinategeometry with the topic length of a straight line.

LENGTH OF LINE

The length of AB is found by usingPythagoras’ Theorem, with AB the hypotenuse ofthe right-angled triangle ABC. As triangle ABCis right-angled, therefore, AB2 = BC2 + AC2.

Given the coordinates of the points A(x1, y1)and B(x2, y2),

AB2 = (x2 - x1)2 + (y2 - y1)2

EXAMPLE

A straight line is drawn through the points X(5 , - 2 ) , Y(3 , 6). Find the length of XY.

Length: XY2 = (x2 - x1)2 + (y2 - y1)2

SubstitutingXY2 = (3 - 5)2 + (6 - - 2)2

= 82 + ( - 2)2 = 4 + 6 4XY = √68

We will try another example.

EXAMPLE

A straight line is drawn through the pointsA(1 , 2) and B(-5 , 4).

Find (i) the gradient of AB(ii) the midpoint of AB

(iii) the length of AB

SOLUTION

(i) The gradient of AB = m = y2 - y1 / x2 - x1

m = 4 - 2 /-5 -1 = 2 = -1/3

(ii) The midpoint of AB is M = x2 + x1 /2, y2 + y1 /2

M = -5 + 1 /2, 4 + 2 /2M = - 4 /2 , 6 /2 = - 2 , 3

(iii) In order to find the length of AB, we usethe formula AB2 = (x2 - x1)2 + (y2 - y1) 2

AB2 = (- 5 - 1)2 + (4 - 2)2

= ( - 6)2 + 22 = 40AB = √40.

If you are to do well on this topic, you mustbear the following in mind:

� Always begin by presenting the requiredformula.

� To calculate the gradient, you may use one

of the following:m = y2 - y1/x2 -x1 or m = y1 - y2 /x1 - x2

I am sure you can prove that both are correct.Note the order of the subscripts; the order isimportant.

� In evaluating the values, be careful toensure the accuracy of the substitution andplease watch the negative signs (directednumbers).

Kindly note the following points with respectto the gradient of a straight line:

� Parallel lines have equal gradient� If perpendicular lines have gradients m1

and m2, then m1 x m2 = -1.� It is clear then that given two lines with

gradients m1 and m2, if they are parallel and m1 = 3/2 , then m2 = 3/2. If they are perpendicularand m1 = 2, then I am sure you agree that m2 = -1/2.

The above will enable you to solve wordproblems with information obtained using theabove.

EXAMPLE

Given that the line joining A(2 , 4) and B(0 ,0) is parallel to XY. Find the gradient of XY.

SOLUTION

The Gradient m, of AB = y2 - y1 / x2 - x1

Substituting,m = 4 - 0 / 2 - 0m = 4/2 = 2As both lines are parallel, then the gradient of

XY is also 2.

EXAMPLE

Given the line through the points A(5 , -2)and B(3 , 4), find the gradient of theperpendicular bisector of AB and its point ofintersection with AB.

SOLUTION

The gradient of AB = m = y2 - y1 / x2 - x1

Substituting

THIS WEEK, we will turn our focus to theexpository section of the internalassessment.

This section of the internal assessment will beorally presented and examined. The durationshould be no longer than 10 minutes perstudent. Topics chosen in this section should becurrent. A student should collect at least twopieces of related information on the selectedtopic. It is usually best to use at least oneprimary source and one secondary source ofinformation. This ensures that the research baseis fairly wide and balanced. This section isworth16 marks.

The marks are allotted as follows:i. Discussion of issues and challenges.

((55 mmaarrkkss))ii. Evaluation of the effect of source, context

and medium (or channel) on the reliability andvalidity of information gathered. ((44 mmaarrkkss))

iii. Organisation. ((33 mmaarrkkss))iv. Delivery (audibility, fluency, eye contact,

body movement and paralinguistic features suchas pauses, throat clearing, pitch, etc). ((44 mmaarrkkss))

In lesson three of this series, I mentioned thatthe presentation should be well-organised andeffectively delivered in standard English. Let usnow look more closely at i and ii above and whatis required of you for each one.

I. DISCUSSION OF ISSUES AND

CHALLENGES. (5 MARKS)

This will look at the issues presented in thearticle or other sources of information used andpersonal/emotional or practical challenges facedwhile exploring the theme and processing theinformation. So, your examiner should have agood sense of the critical issues associated withthe topic you are exploring (for example: ThePrevalence of Human Trafficking in Jamaica). Bynow, you would have read and researchedwidely and be in a position to say whether theincidents of human trafficking are on the rise ordeclining, and what measures the Governmentof Jamaica and other stakeholders have taken toaddress the issues, et cetera. You should also beable to comment on whether the information wasreadily available or what challenges you faced asyou conducted your research and processed theinformation. You can include whether the

interview you conducted with the victim ofhuman trafficking was so emotionally movingthat you had to reschedule the interview in orderto compose yourself. Perhaps all thequestionnaires you distributed were not returnedand this hindered you in some way. Be preparedto share a fulsome discussion of all these.

II. EVALUATION OF THE EFFECT OF

SOURCE, CONTEXT AND MEDIUM (OR

CHANNEL) ON THE RELIABILITY AND

VALIDITY OF INFORMATION

GATHERED. (4 MARKS)

This will look at the expertise, authority, andperspective, social and political bias of theauthor/speaker/source; the social and historicalcontext in which the piece was written/presented; the factual accuracy, logical structureand cogency of the piece. If you review thelesson carried in this series for the last couple ofweeks, you will see how everything falls nicelyinto place. So, as you review your sources,consider whether the author or speaker isdeemed an authority on the matter beingdiscussed. From what perspective are ideasbeing presented? Are they based on personal

experience, professional experience or other?What impact does this have on the information?Does the potential for bias exist in the way theinformation was presented by any of thesources? If so, what impact does it have? Couldthe social, political or historic context in whichthe information was presented have any impacton what was presented or how it was presented?Was Jamaica about to sign a new IMFagreement and, therefore, the article presentedthe country in a very favourable light,economically, in contrast to what your otherresearch indicated was the case? Was theinformation presented factual, free from fallacieswith the points flowing in a logical order fromstart to finish? Were the ideas jumbled andconfusing, making it difficult to decipher andassess?

For written material especially, please makenote of the publisher’s information. Is it areputable source? Is it politically aligned? Is itwell known and highly respected? Please alsopay attention to the date of publication. Somethings remain factual throughout the passage oftime, some secondary sources can beconsidered primary after some time, but new

truths emerge as research widens and deepens,so carefully note the date and how this mayimpact the information presented, especiallywhen compared to other sources of the sameinformation.

III. ORGANISATION (3 MARKS)

Although you have been advised that you maytake into the room ONE cue card – 4” x 6” withheadings/main points related to your presentation– your ideas must be cohesive. Your examinerwill be listening for an introduction, logicalsequence of ideas throughout the body, and aconclusion. It is easier to evaluate one source at atime instead of hopping from one source to theother several times throughout the presentation.As with all oral presentations, remember to makeit as easy as possible for the listener to followwhat is being said.

Next week, we will look at delivering thespeech. You may review the previous lesson inthe series on non-verbal communication.

Analyse the impact of extra-regional countieson the Caribbean.

Historically, the relationship of the Caribbeanto metropolitan countries has been one ofdependency. In the colonial era, Europeanattitudes, ways of life, arts and value systemdominated. While Euro-centric attitudes andvalues were imposed, they created theconditions for their continued hegemony inpost-colonial societies. The interaction of theOld World with the New World is the earliestform of globalisation.

Globalisation is the tendency of businesses totranscend to other markets around the globe,thereby increasing the interconnectedness ofdifferent markets. Modes of transportation aremodernising and the ways of communication aredeveloping. This increases a country’s ability toglobalise. In effect, this means that theCaribbean market is becoming strikingly similarto the markets of extra-regional nations.Caribbean society and culture show anorientation towards the metropole and its impactis perpetuated in:

1. CONSUMPTION PATTERNS

Most of the goods and services consumed inthe Caribbean are produced in North America,and to a lesser extent Britain (for English-speaking countries). In post-independentCaribbean, the desire for what is ‘foreign’ issupported by a number of factors. In history,persons in the Caribbean made a significanteffort to produce their own goods. As timeprogressed, along with the migration of personsfrom America, Europe, or more developedcountries, the mixing of the different cultureshas changed our thoughts of the goods weproduce compared to the goods made abroad.

� The Caribbean people believe their regionis too underdeveloped for producing goods thatcan compete in quality to extra-regionalsocieties.

� The Caribbean’s total imports is likely tobe more than its exports – a dangerous side ofthe status quo.

� The Caribbean people now gravitate toforeign diapers (Huggies, etc) instead ofpurchasing regional diapers, and that is onlyone product!

� Globalisation has instigated theintroduction of some foreign services, such associal security, life insurance and the credit cardculture, into the Caribbean society.

2. CREATIVE EXPRESSIONS

The various ways Caribbean people expressthemselves in festivals, music, theatre arts, etc,reflect their own creations as well as influencesfrom abroad. US penetration of the regionmeans that its influence is expanding throughthe access, of particularly the youth, to its musicfashions and festivals.

i. FFeessttiivvaallss:: Some of the well-establishedChristian and secular festivals that are observedin the Caribbean – Christmas, Easter, Father’sand Mother’s Day, Valentine’s, etc – are extra-regional in origin. They are celebrated in thesame fashion and characterised by the sameextent of commercialism as in developedsocieties. It is the commercial aspect of thecelebrations that marks the degree of Westerninfluence.

Carnival, though not indigenous, had beenmade synonymous with the Caribbean. In recenttimes it, too, has begun to cater to foreign tastesin a number of ways, including:

� The sidelining of calypso with its socialcommentary in favour of the catchier soca.

� The use of computer programs to helpcreate images of costumes.

� The production of videos, DVDs, etc.

ii. TThheeaattrree aarrttss:: Theatre arts includes drama,dance and stagecraft, as well as traditional

dances, folk singing and storytelling. In colonialtimes, Caribbean theatre arts was relegated tothe village communities while the ‘high’ cultureof the British was given pre-eminence. Thedevelopment of theatre arts since independencereflects the influence of extra-regional countriesin respect of:

� Divisions as to the appropriate language,i.e., patios/dialect versus standard English, toconvey the arts.

� Many of the themes in presentationsmirrored the relationship of the Caribbean toextra-regional countries – issues of identity,race, colour and class, etc.

� The migration of many artistes to receivegreater appreciation and rewards for theirtalents, e.g., V.S. Naipaul, Dereck Walcott,Jamaica Kincaid.

3. MIGRATORY LABOUR

From the middle of the 1950s, migration toNorth America and Europe was severelycurtailed as developed countries sought toprotect their economies from unregulatedimmigration. However, in the 1980s, on therecognition of the ageing of these societies,formal arrangements were made to recruitskilled professionals – teacher, nurses.Opportunities were also available for semi-skilled and unskilled labour in sectors notfavoured by citizens, such as agricultural anddomestic work and child care. While theseoccupations are more beneficial to workers vis-á-vis similar work in the Caribbean and theremittances significant to gross national productof Caribbean countries, the programmes’sustainability is decided by the host countries.Any time they are curtailed, suspended ordiscontinued, severe dislocations in the sendingcountries is the result.

4. TOURISM

Caribbean tourism depends almost entirelyfor its survival on visitors from Europe andNorth America. Economic downturns in thesource markets have a negative impact on the

local product. All variants of tourism –adventure, cruise, eco-tourism – are developedon tourists’ demands. Furthermore, the tourisminfrastructure – large hotels, travel agencies, etc,are owned and/or managed in large part byexpatriates. Caribbean countries have developeddifferent kinds of tourist attractions toaccommodate their clienteles. Some are:

� Ecotourism – In Dominica, Belize, Guyanaand Suriname, the rainforests and their flora andfauna cater for nature lovers (people interestedin bird watching). The Mountain Pine Ridge inBelize and coral reefs are also popular.

� Adventure tourism – Guyana andSuriname, the great rivers, offer white-waterrafting and canoeing. Hunting is growing inDominica and mountain climbing in St Lucia.

� Sports tourism – Sea sports: surfing, kiteboarding, sailing, scuba diving, snorkelling, andpowerboat racing. There is the Grenada YachtClub Race, The Spring Regatta of St Maartenand the Blue Marlin Competition in Curacao.

� Health tourism – This is where peoplecome to bathe in mineral-charged watersthought to be good for various ailments. Theyare found in volcanic areas. Example: Jamaica,St Lucia, Dominica and Montserrat, where thereare many hot springs.

� Festival tourism – Carnivals such askadooment in Barbados, the St Lucia Jazz Festival,St Kitts music festival, Reggae Sunsplash inJamaica, and Carnival in Trinidad and Tobago.

� Cruiseship tourism – Caribbean countrieshave constructed docking facilities for majorcruise ships lines such as Carnival, RoyalCaribbean and Princess. Each vessel carriesapproximately 2,000 tourists, a large source offoreign exchange.

At present, tourism is one of the world’slargest industries and for developing countries,it is also one of the biggest income generators.Especially in the Caribbean region, it has both apositive and negative impact on the localeconomy, social life and environment.

to establish an identity as an alternative government.

The Opposition appoints shadow ministers who, with theleader of the Opposition, collectively form a shadow Cabinet. It isalso the duty of the shadow Cabinet to respond to governmentpolicy initiatives and offer alternative policies to the electorate.

ACTIVITIES

1. Suggest THREE reasons why there is a need for a separationof powers in government.

2. Suggest THREE reasons why in a democratic system ofgovernment an opposition is always important.

exposed to stories. Simply put, read and allowwhat you have read to inform the stories youproduce.

Here are some concerns that CXC hasexpressed with stories that suggest anddemonstrate incompetence. As you practisewriting your stories, please avoid these

shortcomings.

AREAS OF CONCERN

� The setting and characters are not clearlyestablished.

� There are too many characters andsettings.

� The series of events are presented as ifthey are being reported.

� Characters and the storyline are not fully

developed.� There is an absence of conflict or any kind

of challenge that would heighten suspense andtension.

� Some students write an essay instead of astory.

� The given stimulus is not used in thestories. For example, the given sentence promptis not included in the story.

� These stories are flawed in their use of

language and organisation.

In next week’s lesson, I will share essentialtips you can bear in mind as you narrate yourstories. In the meantime, increase your efforts atreading more stories.

m = 4 - - 2 / 3 - 5 = 6 / +2 = -3m = -3

Let the gradient of the line perpendicular to AB be m1

m x m1 = -1.-3 x m1 = -1.m1 = -1/3 = 1/3

The midpoint of AB, M, = x2 + x1 / 2, y2 + y1 /2SubstitutingM = 5 + 3 /2, 4 + -2 /2 = (4, 1)

The perpendicular bisector of AB has gradient 1 /3 and passesthrough the point (4, 1).

EXAMPLE

The line l passes through the points S (6, 6) and T (0 , - 2).Determine:1) The gradient of l2) The mid-point of the ST3) The length of ST

SOLUTION

1) Gradient m = y2 - y1 / x2 - x1

Substituting, m = - 2 - 6 / 0 - 6

m = - 8 /-6 = 4 /3

2) Midpoint M = 0 + 6 /2, - 2 + 6 /2 = ( 3 , 2)

3) ST2 = ( 0 - 6)2 + ( - 2 - 6 )2 = (- 6)2 + (- 8 )2

= 36 + 64 = 100ST = 100 = 10.

HOMEWORK

1. Given the points A(-6, 1) and B(4 , - 3) find the followingwith respect to the line AB:

(i) Gradient, m.(ii) midpoint, M. (iii) length of the line AB.(iv) Gradient of XY which is parallel to AB.(v) the gradient of AC which is perpendicular to AB.

2. A straight line K passes through the point M (4, 1) andhas a gradient of 3 . 5

(a) given that the line segment MP is perpendicular to K,determine its gradient.

(b) If the point (x, 4) is a point on the line K, find the valueof x.

3. The coordinates of the points M and N are (- 1, 1) and (3, 9),respectively. Determine the value of:

a. The gradient of MN.

b. The coordinates of the mid-point of the line MN.c. The gradient of MP, the line perpendicular to MN.

All the best for the weekahead.
