68 Brazil
Former Portuguese colony (ca. 1500-1822), once described on old maps as "Portuguese America." Until 1822, the colony of Brazil was Portugal's largest, richest, and most populous colonial territory, and it held the greatest number of overseas Portuguese. Indeed, until 1974, long after Brazil had ceased being a Portuguese colony, the largest number of overseas Portuguese continued to reside in Brazil.Discovered in 1500 by Pedro Álvares Cabral, Brazil experienced significant coastal colonization by Portugal only after 1550. As Portugal's world power and colonial position in North Africa and Asia entered a decline, Brazil began to receive the lion's share of her imperial attention and soon dominated the empire. While Portuguese colonization and civilization had an essential impact on the complex making of Brazil, this fact must be put into perspective. In addition to other European (Italian, German, etc.) and Asian (Japanese) immigrants, two other civilizations or groups of civilizations helped to construct Brazil: the Amerindians who inhabited the land before 1500 and black Africans who were shipped to Brazil's coast as slaves during more than three centuries, mainly from west and central Africa. There is a long history of Portuguese military operations to defend Brazil against internal rebellions as well as other colonial intruders. The French, for example, attacked Brazil several times. But it was the Dutch who proved the greatest threat, when they held northeast Brazil from 1624 to 1654, until they were expelled by Portuguese and colonial forces.Until the 17th century, Portuguese colonization was largely coastal. By the 18th century, Portuguese groups began to penetrate deep into the hinterland, including an area rich in minerals, the Minas Gerais ("General Mines"). Lisbon extracted the greatest wealth from Brazil during the "golden age" of mining of gold and diamonds from 1670 to 1750. But hefty profits for the king also came from Brazilian sugar, tobacco, cotton, woods, and coffee. By the time of Brazil's independence, declared in 1822, Portuguese America had become far more powerful and rich than the mother country. Only a few years before the break, Brazil had been declared a kingdom, in theory on a par with Portugal. A major factor behind the Brazilian independence movement was the impact of the residence of the Portuguese royal family and court in Brazil from 1808 to 1821.What is the Portuguese legacy to Brazil after more than 300 years of colonization? Of the many facets that could be cited, perhaps three are worthy of mention here: the Portuguese language (Brazil is the only Latin American country that has Portuguese as the official language); Portuguese political and administrative customs; and a large community, mostly in coastal Brazil, of overseas Portuguese. -
69 Saldanha, Duke of
(1790-1876)Born João Carlos de Saldanha Oliveira Daun, and later called duke, marshal, count, and marquis of Saldanha, he pursued a military career and personified military intervention in 19th-century politics. Saldanha fought against the French in the Peninsular War, as well as in conflicts in Uruguay and Brazil, and he backed the constitutional monarchist cause of King Pedro IV. Perhaps the most famous of career officers during the century, in his younger years he was often in exile. Critics quipped that his true name was "Dom João VII" for his imperious manner. As minister and prime minister in various liberal governments after 1851, his name later became used as a generic term for an impetuously planned military coup, a "Saldanhada," meaning a military golpe almost whimsical in spirit, carried out by a wild, headstrong general.A soldier from the tender age of 14, Saldanha was a much-discussed figure during various generations of soldiers and politicians. The writer Oliveira Martins later described the man as "a liberal and Portuguese Cid," after El Cid, the Castilian crusading warrior who fought Muslims in medieval Spain. For the constitutional liberal cause of Regent Dom Pedro, Saldanha's personal valor and military prowess were essential in the civil wars, and his prestige in the military was important in the era of the Regeneration of 1851-70; however, this officer lacked political ideas and was out of his element in governance. Queen Maria II, however, in part owed her throne to the force of this military personality who had become a general at age 27. In later life, Saldanha, loaded with honors and freighted with medals, served as Portugal's ambassador in Paris and London, in which city he died at his last post. -

73 privacy policy
E-comthe means by which an organization reassures customers that personal information they supply—usually over the Internet—will be securely protected, and used only for the stated purpose.Most customers are willing to give personal information if they know that it will benefit them. However, privacy is a major concern on the Internet, and needs to be addressed comprehensively. The use of customer information is legislated separately by individual countries, and collecting it and—in particular—moving it between countries can be very complicated, because different countries have different laws.However, a basic principle is for an organization to tell the individual clearly why it is collecting the information, and what that information will be used for. If the organization wishes to use the information for other purposes, such as sending out e-mails on special offers, or sharing with partners, the individual should be specifically informed of that intention, and given the opportunity to opt out.It is good policy for organizations to allow individuals to check the information held on them, and to delete information if they wish to do so. A proper security procedure is essential. Internet security breaches are increasing, and hackers are particularly interested in breaking into systems that contain personal information. -
74 Bigelow, Erastus Brigham
SUBJECT AREA: Textiles[br]b. 2 April 1814 West Boyleston, Massachusetts, USAd. 6 December 1879 USA[br]American inventor of power looms for making lace and many types of carpets.[br]Bigelow was born in West Boyleston, Massachusetts, where his father struggled as a farmer, wheelwright, and chairmaker. Before he was 20, Bigelow had many different jobs, among them farm labourer, clerk, violin player and cotton-mill employee. In 1830, he went to Leicester Academy, Massachusetts, but he could not afford to go on to Harvard. He sought work in Boston, New York and elsewhere, making various inventions.The most important of his early inventions was the power loom of 1837 for making coach lace. This loom contained all the essential features of his carpet looms, which he developed and patented two years later. He formed the Clinton Company for manufacturing carpets at Leicester, Massachusetts, but the factory became so large that its name was adopted for the town. The next twenty years saw various mechanical discoveries, while his range of looms was extended to cover Brussels, Wilton, tapestry and velvet carpets. Bigelow has been justly described as the originator of every fundamental device in these machines, which were amongst the largest textile machines of their time. The automatic insertion and withdrawal of strong wires with looped ends was the means employed to raise the looped pile of the Brussels carpets, while thinner wires with a knife blade at the end raised and then severed the loops to create the rich Wilton pile. At the Great Exhibition in 1851, it was declared that his looms made better carpets than any from hand looms. He also developed other looms for special materials.He became a noted American economist, writing two books about tariff problems, advocating that the United States should not abandon its protectionist policies. In 1860 he was narrowly defeated in a Congress election. The following year he was a member of the committee that established the Massachusetts Institute of Technology.[br]Further ReadingNational Cyclopedia of American Biography III (the standard account of his life).

75 Crompton, Samuel
SUBJECT AREA: Textiles[br]b. 3 December 1753 Firwood, near Bolton, Lancashire, Englandd. 26 June 1827 Bolton, Lancashire, England[br]English inventor of the spinning mule.[br]Samuel Crompton was the son of a tenant farmer, George, who became the caretaker of the old house Hall-i-th-Wood, near Bolton, where he died in 1759. As a boy, Samuel helped his widowed mother in various tasks at home, including weaving. He liked music and made his own violin, with which he later was to earn some money to pay for tools for building his spinning mule. He was set to work at spinning and so in 1769 became familiar with the spinning jenny designed by James Hargreaves; he soon noticed the poor quality of the yarn produced and its tendency to break. Crompton became so exasperated with the jenny that in 1772 he decided to improve it. After seven years' work, in 1779 he produced his famous spinning "mule". He built the first one entirely by himself, principally from wood. He adapted rollers similar to those already patented by Arkwright for drawing out the cotton rovings, but it seems that he did not know of Arkwright's invention. The rollers were placed at the back of the mule and paid out the fibres to the spindles, which were mounted on a moving carriage that was drawn away from the rollers as the yarn was paid out. The spindles were rotated to put in twist. At the end of the draw, or shortly before, the rollers were stopped but the spindles continued to rotate. This not only twisted the yarn further, but slightly stretched it and so helped to even out any irregularities; it was this feature that gave the mule yarn extra quality. Then, after the spindles had been turned backwards to unwind the yarn from their tips, they were rotated in the spinning direction again and the yarn was wound on as the carriage was pushed up to the rollers.The mule was a very versatile machine, making it possible to spin almost every type of yarn. In fact, Samuel Crompton was soon producing yarn of a much finer quality than had ever been spun in Bolton, and people attempted to break into Hall-i-th-Wood to see how he produced it. Crompton did not patent his invention, perhaps because it consisted basically of the essential features of the earlier machines of Hargreaves and Arkwright, or perhaps through lack of funds. Under promise of a generous subscription, he disclosed his invention to the spinning industry, but was shabbily treated because most of the promised money was never paid. Crompton's first mule had forty-eight spindles, but it did not long remain in its original form for many people started to make improvements to it. The mule soon became more popular than Arkwright's waterframe because it could spin such fine yarn, which enabled weavers to produce the best muslin cloth, rivalling that woven in India and leading to an enormous expansion in the British cotton-textile industry. Crompton eventually saved enough capital to set up as a manufacturer himself and around 1784 he experimented with an improved carding engine, although he was not successful. In 1800, local manufacturers raised a sum of £500 for him, and eventually in 1812 he received a government grant of £5,000, but this was trifling in relation to the immense financial benefits his invention had conferred on the industry, to say nothing of his expenses. When Crompton was seeking evidence in 1811 to support his claim for financial assistance, he found that there were 4,209,570 mule spindles compared with 155,880 jenny and 310,516 waterframe spindles. He later set up as a bleacher and again as a cotton manufacturer, but only the gift of a small annuity by his friends saved him from dying in total poverty.[br]Further ReadingH.C.Cameron, 1951, Samuel Crompton, Inventor of the Spinning Mule, London (a rather discursive biography).Dobson \& Barlow Ltd, 1927, Samuel Crompton, the Inventor of the Spinning Mule, Bolton.G.J.French, 1859, The Life and Times of Samuel Crompton, Inventor of the Spinning Machine Called the Mule, London.The invention of the mule is fully described in H.

76 Darby, Abraham
SUBJECT AREA: Metallurgy[br]b. 1678 near Dudley, Worcestershire, Englandd. 5 May 1717 Madely Court, Coalbrookdale, Shropshire, England[br]English ironmaster, inventor of the coke smelting of iron ore.[br]Darby's father, John, was a farmer who also worked a small forge to produce nails and other ironware needed on the farm. He was brought up in the Society of Friends, or Quakers, and this community remained important throughout his personal and working life. Darby was apprenticed to Jonathan Freeth, a malt-mill maker in Birmingham, and on completion of his apprenticeship in 1699 he took up the trade himself in Bristol. Probably in 1704, he visited Holland to study the casting of brass pots and returned to Bristol with some Dutch workers, setting up a brassworks at Baptist Mills in partnership with others. He tried substituting cast iron for brass in his castings, without success at first, but in 1707 he was granted a patent, "A new way of casting iron pots and other pot-bellied ware in sand without loam or clay". However, his business associates were unwilling to risk further funds in the experiments, so he withdrew his share of the capital and moved to Coalbrookdale in Shropshire. There, iron ore, coal, water-power and transport lay close at hand. He took a lease on an old furnace and began experimenting. The shortage and expense of charcoal, and his knowledge of the use of coke in malting, may well have led him to try using coke to smelt iron ore. The furnace was brought into blast in 1709 and records show that in the same year it was regularly producing iron, using coke instead of charcoal. The process seems to have been operating successfully by 1711 in the production of cast-iron pots and kettles, with some pig-iron destined for Bristol. Darby prospered at Coalbrookdale, employing coke smelting with consistent success, and he sought to extend his activities in the neighbourhood and in other parts of the country. However, ill health prevented him from pursuing these ventures with his previous energy. Coke smelting spread slowly in England and the continent of Europe, but without Darby's technological breakthrough the ever-increasing demand for iron for structures and machines during the Industrial Revolution simply could not have been met; it was thus an essential component of the technological progress that was to come.Darby's eldest son, Abraham II (1711–63), entered the Coalbrookdale Company partnership in 1734 and largely assumed control of the technical side of managing the furnaces and foundry. He made a number of improvements, notably the installation of a steam engine in 1742 to pump water to an upper level in order to achieve a steady source of water-power to operate the bellows supplying the blast furnaces. When he built the Ketley and Horsehay furnaces in 1755 and 1756, these too were provided with steam engines. Abraham II's son, Abraham III (1750–89), in turn, took over the management of the Coalbrookdale works in 1768 and devoted himself to improving and extending the business. His most notable achievement was the design and construction of the famous Iron Bridge over the river Severn, the world's first iron bridge. The bridge members were cast at Coalbrookdale and the structure was erected during 1779, with a span of 100 ft (30 m) and height above the river of 40 ft (12 m). The bridge still stands, and remains a tribute to the skill and judgement of Darby and his workers.[br]Further ReadingA.Raistrick, 1989, Dynasty of Iron Founders, 2nd edn, Ironbridge Gorge Museum Trust (the best source for the lives of the Darbys and the work of the company).H.R.Schubert, 1957, History of the British Iron and Steel Industry AD 430 to AD 1775, London: Routledge \& Kegan Paul.LRD -
77 Heathcote, John
SUBJECT AREA: Textiles[br]b. 7 August 1783 Duffield, Derbyshire, Englandd. 18 January 1861 Tiverton, Devonshire, England[br]English inventor of the bobbin-net lace machine.[br]Heathcote was the son of a small farmer who became blind, obliging the family to move to Long Whatton, near Loughborough, c.1790. He was apprenticed to W.Shepherd, a hosiery-machine maker, and became a frame-smith in the hosiery industry. He moved to Nottingham where he entered the employment of an excellent machine maker named Elliott. He later joined William Caldwell of Hathern, whose daughter he had married. The lace-making apparatus they patented jointly in 1804 had already been anticipated, so Heathcote turned to the problem of making pillow lace, a cottage industry in which women made lace by arranging pins stuck in a pillow in the correct pattern and winding around them thread contained on thin bobbins. He began by analysing the complicated hand-woven lace into simple warp and weft threads and found he could dispense with half the bobbins. The first machine he developed and patented, in 1808, made narrow lace an inch or so wide, but the following year he made much broader lace on an improved version. In his second patent, in 1809, he could make a type of net curtain, Brussels lace, without patterns. His machine made bobbin-net by the use of thin brass discs, between which the thread was wound. As they passed through the warp threads, which were arranged vertically, the warp threads were moved to each side in turn, so as to twist the bobbin threads round the warp threads. The bobbins were in two rows to save space, and jogged on carriages in grooves along a bar running the length of the machine. As the strength of this fabric depended upon bringing the bobbin threads diagonally across, in addition to the forward movement, the machine had to provide for a sideways movement of each bobbin every time the lengthwise course was completed. A high standard of accuracy in manufacture was essential for success. Called the "Old Loughborough", it was acknowledged to be the most complicated machine so far produced. In partnership with a man named Charles Lacy, who supplied the necessary capital, a factory was established at Loughborough that proved highly successful; however, their fifty-five frames were destroyed by Luddites in 1816. Heathcote was awarded damages of £10,000 by the county of Nottingham on the condition it was spent locally, but to avoid further interference he decided to transfer not only his machines but his entire workforce elsewhere and refused the money. In a disused woollen factory at Tiverton in Devonshire, powered by the waters of the river Exe, he built 300 frames of greater width and speed. By continually making inventions and improvements until he retired in 1843, his business flourished and he amassed a large fortune. He patented one machine for silk cocoon-reeling and another for plaiting or braiding. In 1825 he brought out two patents for the mechanical ornamentation or figuring of lace. He acquired a sound knowledge of French prior to opening a steam-powered lace factory in France. The factory proved to be a successful venture that lasted many years. In 1832 he patented a monstrous steam plough that is reputed to have cost him over £12,000 and was claimed to be the best in its day. One of its stated aims was "improved methods of draining land", which he hoped would develop agriculture in Ireland. A cable was used to haul the implement across the land. From 1832 to 1859, Heathcote represented Tiverton in Parliament and, among other benefactions, he built a school for his adopted town.[br]Bibliography1804, with William Caldwell, British patent no. 2,788 (lace-making machine). 1808.

78 Spencer, Christopher Miner
[br]b. 10 June 1833 Manchester, Connecticut, USAd. 14 January 1922 Hartford, Connecticut, USA[br]American mechanical engineer and inventor.[br]Christopher M.Spencer served an apprenticeship from 1847 to 1849 in the machine shop at the silk mills of Cheney Brothers in his native town and remained there for a few years as a journeyman machinist. In 1853 he went to Rochester, New York, to obtain experience with machinery other than that used in the textile industry. He then spent some years with the Colt Armory at Hartford, Connecticut, before returning to Cheney Brothers, where he obtained his first patent, which was for a silk-winding machine.Spencer had long been interested in firearms and in 1860 he obtained a patent for a repeating rifle. The Spencer Repeating Rifle Company was organized for its manufacture, and before the end of the American Civil War about 200,000 rifles had been produced. He patented a number of other improvements in firearms and in 1868 was associated with Charles E.Billings (1835–1920) in the Roper Arms Company, set up at Amherst, Massachusetts, to manufacture Spencer's magazine gun. This was not a success, however, and in 1869 they moved to Hartford, Connecticut, and formed the Billings \& Spencer Company. There they developed the technology of the drop hammer and Spencer continued his inventive work, which included an automatic turret lathe for producing metal screws. The patent that he obtained for this in 1873 inexplicably failed to protect the essential feature of the machine which provided the automatic action, with the result that Spencer received no patent right on the most valuable feature of the machine.In 1874 Spencer withdrew from active connection with Billings \& Spencer, although he remained a director, and in 1876 he formed with others the Hartford Machine Screw Company. However, he withdrew in 1882 to form the Spencer Arms Company at Windsor, Connecticut, for the manufacture of another of his inventions, a repeating shotgun. But this company failed and Spencer returned to the field of automatic lathes, and in 1893 he organized the Spencer Automatic Machine Screw Company at Windsor, where he remained until his retirement.[br]Further ReadingJ.W.Roe, 1916, English and American Tool Builders, New Haven; reprinted 1926, New York, and 1987, Bradley, Ill.

80 Computers
The brain has been compared to a digital computer because the neuron, like a switch or valve, either does or does not complete a circuit. But at that point the similarity ends. The switch in the digital computer is constant in its effect, and its effect is large in proportion to the total output of the machine. The effect produced by the neuron varies with its recovery from [the] refractory phase and with its metabolic state. The number of neurons involved in any action runs into millions so that the influence of any one is negligible.... Any cell in the system can be dispensed with.... The brain is an analogical machine, not digital. Analysis of the integrative activities will probably have to be in statistical terms. (Lashley, quoted in Beach, Hebb, Morgan & Nissen, 1960, p. 539)It is essential to realize that a computer is not a mere "number cruncher," or supercalculating arithmetic machine, although this is how computers are commonly regarded by people having no familiarity with artificial intelligence. Computers do not crunch numbers; they manipulate symbols.... Digital computers originally developed with mathematical problems in mind, are in fact general purpose symbol manipulating machines....The terms "computer" and "computation" are themselves unfortunate, in view of their misleading arithmetical connotations. The definition of artificial intelligence previously cited-"the study of intelligence as computation"-does not imply that intelligence is really counting. Intelligence may be defined as the ability creatively to manipulate symbols, or process information, given the requirements of the task in hand. (Boden, 1981, pp. 15, 16-17)The task is to get computers to explain things to themselves, to ask questions about their experiences so as to cause those explanations to be forthcoming, and to be creative in coming up with explanations that have not been previously available. (Schank, 1986, p. 19)In What Computers Can't Do, written in 1969 (2nd edition, 1972), the main objection to AI was the impossibility of using rules to select only those facts about the real world that were relevant in a given situation. The "Introduction" to the paperback edition of the book, published by Harper & Row in 1979, pointed out further that no one had the slightest idea how to represent the common sense understanding possessed even by a four-year-old. (Dreyfus & Dreyfus, 1986, p. 102)A popular myth says that the invention of the computer diminishes our sense of ourselves, because it shows that rational thought is not special to human beings, but can be carried on by a mere machine. It is a short stop from there to the conclusion that intelligence is mechanical, which many people find to be an affront to all that is most precious and singular about their humanness.In fact, the computer, early in its career, was not an instrument of the philistines, but a humanizing influence. It helped to revive an idea that had fallen into disrepute: the idea that the mind is real, that it has an inner structure and a complex organization, and can be understood in scientific terms. For some three decades, until the 1940s, American psychology had lain in the grip of the ice age of behaviorism, which was antimental through and through. During these years, extreme behaviorists banished the study of thought from their agenda. Mind and consciousness, thinking, imagining, planning, solving problems, were dismissed as worthless for anything except speculation. Only the external aspects of behavior, the surface manifestations, were grist for the scientist's mill, because only they could be observed and measured....It is one of the surprising gifts of the computer in the history of ideas that it played a part in giving back to psychology what it had lost, which was nothing less than the mind itself. In particular, there was a revival of interest in how the mind represents the world internally to itself, by means of knowledge structures such as ideas, symbols, images, and inner narratives, all of which had been consigned to the realm of mysticism. (Campbell, 1989, p. 10)[Our artifacts] only have meaning because we give it to them; their intentionality, like that of smoke signals and writing, is essentially borrowed, hence derivative. To put it bluntly: computers themselves don't mean anything by their tokens (any more than books do)-they only mean what we say they do. Genuine understanding, on the other hand, is intentional "in its own right" and not derivatively from something else. (Haugeland, 1981a, pp. 32-33)he debate over the possibility of computer thought will never be won or lost; it will simply cease to be of interest, like the previous debate over man as a clockwork mechanism. (Bolter, 1984, p. 190)t takes us a long time to emotionally digest a new idea. The computer is too big a step, and too recently made, for us to quickly recover our balance and gauge its potential. It's an enormous accelerator, perhaps the greatest one since the plow, twelve thousand years ago. As an intelligence amplifier, it speeds up everything-including itself-and it continually improves because its heart is information or, more plainly, ideas. We can no more calculate its consequences than Babbage could have foreseen antibiotics, the Pill, or space stations.Further, the effects of those ideas are rapidly compounding, because a computer design is itself just a set of ideas. As we get better at manipulating ideas by building ever better computers, we get better at building even better computers-it's an ever-escalating upward spiral. The early nineteenth century, when the computer's story began, is already so far back that it may as well be the Stone Age. (Rawlins, 1997, p. 19)According to weak AI, the principle value of the computer in the study of the mind is that it gives us a very powerful tool. For example, it enables us to formulate and test hypotheses in a more rigorous and precise fashion than before. But according to strong AI the computer is not merely a tool in the study of the mind; rather the appropriately programmed computer really is a mind in the sense that computers given the right programs can be literally said to understand and have other cognitive states. And according to strong AI, because the programmed computer has cognitive states, the programs are not mere tools that enable us to test psychological explanations; rather, the programs are themselves the explanations. (Searle, 1981b, p. 353)What makes people smarter than machines? They certainly are not quicker or more precise. Yet people are far better at perceiving objects in natural scenes and noting their relations, at understanding language and retrieving contextually appropriate information from memory, at making plans and carrying out contextually appropriate actions, and at a wide range of other natural cognitive tasks. People are also far better at learning to do these things more accurately and fluently through processing experience.What is the basis for these differences? One answer, perhaps the classic one we might expect from artificial intelligence, is "software." If we only had the right computer program, the argument goes, we might be able to capture the fluidity and adaptability of human information processing. Certainly this answer is partially correct. There have been great breakthroughs in our understanding of cognition as a result of the development of expressive high-level computer languages and powerful algorithms. However, we do not think that software is the whole story.In our view, people are smarter than today's computers because the brain employs a basic computational architecture that is more suited to deal with a central aspect of the natural information processing tasks that people are so good at.... hese tasks generally require the simultaneous consideration of many pieces of information or constraints. Each constraint may be imperfectly specified and ambiguous, yet each can play a potentially decisive role in determining the outcome of processing.
