49 complex adaptive system
Gen Mgta system that overrides conventional human controls because those controls will subdue inevitable change and development within that system. Complex adaptive systems are a product of the application of chaos theory (see chaos) and complexity theory to the world of organizations. According to writers such as Richard Pascale, organizations that are subject to too much control are at risk of failure. The bureaucracy has been cited as an example of extreme control and the top down approach to management. However, if a bureaucracy is left to adapt naturally, it could become capable of self-organization and of creating new methods of operating. -
50 content management
E-comthe means and methods of managing the textual and graphical content of a Web site. For large sites with thousands of pages and many interchangeable words and images, it pays to invest in a content management application system that facilitates the creation and organization of Web content. Some content management systems also offer caching (where a server stores frequently requested information) and analysis of site traffic.Recent years have seen a vast growth in the quantity of content produced by organizations, particularly in digital form. In 2001, it was estimated that there were over 550 billion documents on Internet, intranet, and extranet websites—making professional content management vital. Without it, it becomes almost impossible for a user to find the information they are looking for.However, excellent content management is expensive, and organizations need to establish a solid business case in order to justify it. The initial point for consideration is that content is not a low-level commodity that merely needs to be stored—it is a critical resource, and its value lies in it being read. So an understanding of who will read it is essential. Decisions need to be taken over what languages the material needs to be published in, and in what media (Web or e-mail, for example). The form of the content—text, audio, video—is also important, as is the sensitivity of the material and the consequent security required.Simply storing content is data management, but content management should have publication as its main focus, with the intention of informing or entertaining readers. There is a big difference in approach between the two. -

52 management science
Gen Mgtthe application of scientific methods and principles to management decision making and problem solving. Management science encompasses the use of quantitative, mathematical, and statistical techniques. The term can be used to denote scientific management, which has origins in the work of Frederick Winslow Taylor, Henry Gantt, and Frank and Lillian Gilbreth. Management science lies at the opposite end of the spectrum to the human relations school. -
53 operational research
Gen Mgtthe application of scientific methods to the solution of managerial and administrative problems, involving complex systems or processes. Operational research strives to find the optimum plan for the control and operation of a system or process. It was originally used during World War II as a means of solving logistical problems. It has since developed into a planning, scheduling, and problem solving technique applied across the industrial, commercial, and public sectors. -
54 Denny, William
SUBJECT AREA: Ports and shipping[br]b. 25 May 1847 Dumbarton, Scotlandd. 17 March 1887 Buenos Aires, Argentina[br]Scottish naval architect and partner in the leading British scientific shipbuilding company.[br]From 1844 until 1962, the Clyde shipyard of William Denny and Brothers, Dumbarton, produced over 1,500 ships, trained innumerable students of all nationalities in shipbuilding and marine engineering, and for the seventy-plus years of their existence were accepted worldwide as the leaders in the application of science to ship design and construction. Until the closure of the yard members of the Denny family were among the partners and later directors of the firm: they included men as distinguished as Dr Peter Denny (1821(?)–95), Sir Archibald Denny (1860–1936) and Sir Maurice Denny (1886– 1955), the main collaborator in the design of the Denny-Brown ship stabilizer.One of the most influential of this shipbuilding family was William Denny, now referred to as William 3! His early education was at Dumbarton, then on Jersey and finally at the Royal High School, Edinburgh, before he commenced an apprenticeship at his father's shipyard. From the outset he not only showed great aptitude for learning and hard work but also displayed an ability to create good relationships with all he came into contact with. At the early age of 21 he was admitted a partner of the shipbuilding business of William Denny and Brothers, and some years later also of the associated engineering firm of Denny \& Co. His deep-felt interest in what is now known as industrial relations led him in 1871 to set up a piecework system of payment in the shipyard. In this he was helped by the Yard Manager, Richard Ramage, who later was to found the Leith shipyard, which produced the world's most elegant steam yachts. This research was published later as a pamphlet called The Worth of Wages, an unusual and forward-looking action for the 1860s, when Denny maintained that an absentee employer should earn as much contempt and disapproval as an absentee landlord! In 1880 he initiated an awards scheme for all company employees, with grants and awards for inventions and production improvements. William Denny was not slow to impose new methods and to research naval architecture, a special interest being progressive ship trials with a view to predicting effective horsepower. In time this led to his proposal to the partners to build a ship model testing tank beside the Dumbarton shipyard; this scheme was completed in 1883 and was to the third in the world (after the Admiralty tank at Torquay, managed by William Froude and the Royal Netherlands Navy facility at Amsterdam, under B.J. Tideman. In 1876 the Denny Shipyard started work with mild-quality shipbuilding steel on hulls for the Irrawaddy Flotilla Company, and in 1879 the world's first two ships of any size using this weight-saving material were produced: they were the Rotomahana for the Union Steamship Company of New Zealand and the Buenos Ayrean for the Allan Line of Glasgow. On the naval-architecture side he was involved in Denny's proposals for standard cross curves of stability for all ships, which had far-reaching effects and are now accepted worldwide. He served on the committee working on improvements to the Load Line regulations and many other similar public bodies. After a severe bout of typhoid and an almost unacceptable burden of work, he left the United Kingdom for South America in June 1886 to attend to business with La Platense Flotilla Company, an associate company of William Denny and Brothers. In March the following year, while in Buenos Aires, he died by his own hand, a death that caused great and genuine sadness in the West of Scotland and elsewhere.[br]Principal Honours and DistinctionsPresident, Institution of Engineers and Shipbuilders in Scotland 1886. FRS Edinburgh 1879.BibliographyWilliam Denny presented many papers to various bodies, the most important being to the Institution of Naval Architects and to the Institution of Engineers and Shipbuilders in Scotland. The subjects include: trials results, the relation of ship speed to power, Lloyd's Numerals, tonnage measurement, layout of shipyards, steel in shipbuilding, cross curves of stability, etc.Further ReadingA.B.Bruce, 1889, The Life of William Denny, Shipbuilder, London: Hodder \& Stoughton.Denny Dumbarton 1844–1932 (a souvenir hard-back produced for private circulation by the shipyard).Fred M.Walker, 1984, Song of the Clyde.

55 Garforth, William Edward
SUBJECT AREA: Mining and extraction technology[br]b. 1845 Dukinfield, Cheshire, Englandd. 1 October 1921 Pontefract, Yorkshire, England[br]English colliery manager, pioneer in machine-holing and the safety of mines.[br]After Menzies conceived his idea of breaking off coal with machines in 1761, many inventors subsequently followed his proposals through into the practice of underground working. More than one century later, Garforth became one of the principal pioneers of machine-holing combined with the longwall method of working in order to reduce production costs and increase the yield of coal. Having been appointed agent to Pope \& Pearson's Collieries, West Yorkshire, in 1879, of which company he later became Managing Director and Chairman, he gathered a great deal of experience with different methods of cutting coal. The first disc machine was exhibited in London as early as 1851, and ten years later a pick machine was invented. In 1893 he introduced an improved type of deep undercutting machine, his "diamond" disc coal-cutter, driven by compressed air, which also became popular on the European continent.Besides the considerable economic advantages it created, the use of machinery for mining coal increased the safety of working in hard and thin seams. The improvement of safety in mining technology was always his primary concern, and as a result of his inventions and his many publications he became the leading figure in the British coal mining industry at the beginning of the twentieth century; safety lamps still carry his name. In 1885 he invented a firedamp detector, and following a severe explosion in 1886 he concentrated on coal-dust experiments. From the information he obtained of the effect of stone-dust on a coal-dust explosion he proposed the stone-dust remedy to prevent explosions of coal-dust. As a result of discussions which lasted for decades and after he had been entrusted with the job of conducting the British coal-dust experiments, in 1921 an Act made it compulsory in all mines which were not naturally wet throughout to treat all roads with incombustible dust so as to ensure that the dust always consisted of a mixture containing not more than 50 per cent combustible matter. In 1901 Garforth erected a surface gallery which represented the damaged roadways of a mine and could be filled with noxious fumes to test self-contained breathing apparata. This gallery formed the model from which all the rescue-stations existing nowadays have been developed.[br]Principal Honours and DistinctionsKnighted 1914.

56 Jacobi, Moritz Hermann von
SUBJECT AREA: Electricity[br]b. 21 September 1801 Potsdam, Germanyd. 27 February 1874 St Petersburg, Russia[br]German scientist who developed one of the first practical electric motors.[br]After studying architecture at Göttingen University, Jacobi turned his attention to physics and chemistry. In 1835 he was appointed a professor of civil engineering at the University of Dorpat (which later assumed the Estonian name of Tartu). Later, moving to St Petersburg, he became a member of the Imperial Academy of Sciences and commenced research on electricity and its practical applications. In December 1834 Jacobi presented a paper to the Academy of Sciences in Paris in which he stated that he had obtained rotation by electromagnetic methods in May of that year. Tsar Nicholas of Russia gave him a grant to prove that his electric motor had a practical application. Jacobi had a boat constructed that measured 28 ft in length and was propelled by paddles connected to an electric motor of his own design. Powered by Grove cells, it carried about fourteen passengers at a speed of almost 3 mph (5 km/h) on the River Neva. The weight of and possibly the fumes from the batteries contributed to the abandonment of the project. In 1839 Jacobi introduced electrotyping, i.e. the reproduction of forms by electrodeposition, which was one of the first commercial applications of electricity. In 1840 he reported the results of his investigations into the power of the electromagnet as a function of various parameters to the British Association.[br]Principal Honours and DistinctionsMember, Imperial Academy of Sciences, St Petersburg, 1847.BibliographyJacobi's papers are listed in Catalogue of Scientific Papers, 1868, Vol. III, London: Royal Society, pp. 517–18.1837, Annals of Electricity 1:408–15 and 419–44 (describes his motor).Further ReadingBiography, 1876, Bulletin de l'Académie imperiale des sciences de St Petersburg 21:262–79.E.H.Huntress, 1951, in Proceedings of the American Academy of Arts and Sciences 79: 22–3 (a short biography).B.Bowers, 1982, A History of Electric Light and Power, London.GWBiographical history of technology > Jacobi, Moritz Hermann von

57 Laithwaite, Eric Roberts
[br]b. 14 June 1921 Atherton, Lancashire, England[br]English engineer, notable contributor to the development of linear electric motors.[br]Laithwaite's education at Kirkham Grammar School and Regent Street Polytechnic, London, was followed by service in the Royal Air Force. After entering Manchester University in 1946 and graduating in 1949, he joined the university staff and became Secretary to the Inaugural Conference of the Ferranti Mark I computer. In 1964 he moved to Imperial College of Science and Technology, London, and became Professor of Heavy Electrical Engineering. From 1967 to 1976 he also held the post of External Professor of Applied Electricity at the Royal Institution. Research into the use of linear induction motors as shuttle drives in weaving looms was followed by investigations into their application to conveyors in industrial processes and as high-speed propulsion units for railway vehicles. With considerable involvement in a tracked hovercraft project in the 1960s and 1970s, he proposed the concept of transverse flux and the magnetic river high-speed linear induction machine. Linear motors and electromagnetic levitation have been applied to high-speed propulsion in the United States, France and Japan.Laithwaite has written five books and over one hundred papers on the subjects of linear motors and electromagnetic levitation. Two series of Christmas lectures were presented by him at the Royal Institution.[br]Principal Honours and DistinctionsRoyal Society S.G.Brown Medal 1966.

59 Maxwell, James Clerk
[br]b. 13 June 1831 Edinburgh, Scotlandd. 5 November 1879 Cambridge, England[br]Scottish physicist who formulated the unified theory of electromagnetism, the kinetic theory of gases and a theory of colour.[br]Maxwell attended school at the Edinburgh Academy and at the age of 16 went on to study at Edinburgh University. In 1850 he entered Trinity College, Cambridge, where he graduated four years later as Second Wrangler with the award of the Smith's Prize. Two years later he was appointed Professor at Marischal College, Aberdeen, where he married the Principal's daughter. In 1860 he moved to King's College London, but on the death of his father five years later, Maxwell returned to the family home in Scotland, where he continued his researches as far as the life of a gentleman farmer allowed. This rural existence was interrupted in 1874 when he was persuaded to accept the chair of Cavendish Professor of Experimental Physics at Cambridge. Unfortunately, in 1879 he contracted the cancer that brought his brilliant career to an untimely end. While at Cambridge, Maxwell founded the Cavendish Laboratory for research in physics. A succession of distinguished physicists headed the laboratory, making it one of the world's great centres for notable discoveries in physics.During the mid-1850s, Maxwell worked towards a theory to explain electrical and magnetic phenomena in mathematical terms, culminating in 1864 with the formulation of the fundamental equations of electromagnetism (Maxwell's equations). These equations also described the propagation of light, for he had shown that light consists of transverse electromagnetic waves in a hypothetical medium, the "ether". This great synthesis of theories uniting a wide range of phenomena is worthy to set beside those of Sir Isaac Newton and Einstein. Like all such syntheses, it led on to further discoveries. Maxwell himself had suggested that light represented only a small part of the spectrum of electromagnetic waves, and in 1888 Hertz confirmed the discovery of another small part of the spectrum, radio waves, with momentous implications for the development of telecommunication technology. Maxwell contributed to the kinetic theory of gases, which by then were viewed as consisting of a mass of randomly moving molecules colliding with each other and with the walls of the containing vessel. From 1869 Maxwell applied statistical methods to describe the molecular motion in mathematical terms. This led to a greater understanding of the behaviour of gases, with important consequences for the chemical industry.Of more direct technological application was Maxwell's work on colour vision, begun in 1849, showing that all colours could be derived from the three primary colours, red, yellow and blue. This enabled him in 1861 to produce the first colour photograph, of a tartan. Maxwell's discoveries about colour vision were quickly taken up and led to the development of colour printing and photography.[br]BibliographyMost of his technical papers are reprinted in The Scientific Papers of J.Clerk Maxwell, 1890, ed.

60 Perkin, Sir William Henry
[br]b. 12 March 1838 London, Englandd. 14 July 1907 Sudbury, England[br]English chemist, discoverer of aniline dyes, the first synthetic dyestuffs.[br]He early showed an aptitude for chemistry and in 1853 entered the Royal College of Chemistry as a student under A.W.von Hofmann, the first Professor at the College. By the end of his first year, he had carried out his first piece of chemical research, on the action of cyanogen chloride on phenylamine, which he published in the Journal of the Chemical Society (1857). He became honorary assistant to von Hofmann in 1857; three years previously he had set up his own chemical laboratory at home, where he had discovered the first of the azo dyes, aminoazonapththalene. In 1856 Perkin began work on the synthesis of quinine by oxidizing a salt of allyl toluidine with potassium dichromate. Substituting aniline, he obtained a dark-coloured precipitate which proved to possess dyeing properties: Perkin had discovered the first aniline dye. Upon receiving favourable reports on the new material from manufacturers of dyestuffs, especially Pullars of Perth, Perkin resigned from the College and turned to the commercial exploitation of his discovery. This proved highly successful. From 1858, the dye was manufactured at his Greenford Green works as "Aniline Purple" or "Tyrian Purple". It was later to be referred to by the French as mauve. Perkin's discovery led to the development of the modern dyestuffs industry, supplanting dyes from the traditional vegetable sources. In 1869, he introduced two new methods for making the red dye alizarin, in place of the process that involved the use of the madder plant (Rubia tinctorum). In spite of German competition, he dominated the British market until the end of 1873. After eighteen years in chemical industry, Perkin retired and devoted himself entirely to the pure chemical research which he had been pursuing since the 1850s. He eventually contributed ninety papers to the Chemical Society and further papers to other bodies, including the Royal Society. For example, in 1867 he published his synthesis of unsaturated organic acids, known as "Perkin's synthesis". Other papers followed, on the structure of "Aniline Purple". In 1881 Perkin drew attention to the magnetic-rotatory power of some of the substances he had been dealing with. From then on, he devoted particular attention to the application of this phenomenon to the determination of chemical structure.Perkin won wide recognition for his discoveries and other contributions to chemistry.The half-centenary of his great discovery was celebrated in July 1906 and later that year he received a knighthood.[br]Principal Honours and DistinctionsKnighted 1906.
