21 CPD
abbr. HRcontinuing professional development: ongoing training and education throughout a career to improve the skills and knowledge used to perform a job or succession of jobs. CPD should be a planned, structured process, involving the assessment of development needs and the tailoring of training to meet those needs. CPD is founded on the belief that the development of professionals should not finish after initial qualification, especially in a fast changing business environment in which skills are likely to obsolesce quickly. CPD requires commitment and resources from the employee, the employer, and supportive agencies such as professional bodies. Advocates of CPD argue that it can enhance employability and career development by keeping skills up to date and broadening a person’s skill base. Dominic Cadbury has said that CPD should be centered on the individual, who must take responsibility for the continuing assessment and satisfaction of his or her own development needs. Much can be found in support of the principle of CPD in the concepts of David Kolb’s experiential learning cycle, Peter Honey and Alan Mumford’s learning types, the personal development cycle, and lifelong learning. -

35 P2P
abbr. E-compeer-to-peer: a means of optimizing the networking capabilities of the Internet among groups of computers. Effectively it puts every computer on an equal footing, in that each can be both a publisher and consumer of information. The traditional model on the Web is the client-server one: the client is a computer that is able only to receive information; the server, on the other hand, publishes information on a Web site. Peer-to-peer makes a computer both a server and a client. Perhaps the best-known example of peer-to-peer is Napster, which enabled person A to search for and download music from person B’s computer, while person B could search for and download music from person A’s computer.There are several options for the use of peer-to-peer technologies. Information/ content: where the content on your computer becomes accessible to everyone else in the peer-to-peer environment, and vice versa. Processing sharing: where computers with spare processing capacity network together in order to combine resources. Using a large number of computers, this can create very significant processing capabilities. Services: a computer user can offer services to other people in the peer-to-peer network. File sharing: if person A downloads a file from a central server (an e-learning course from the Internet, for example), other people can use it from person A’s machine instead of having to download it again, significantly reducing strain on bandwidth.The main problem with peer-to-peer is the issue of security, and therefore it is essential to authenticate users. Many peer-to-peer interactions also use encryption, which ensures that the communication is secure as it is being passed from computer to computer. -
36 Pliny the Elder (Gaius Plinius Secundus)
SUBJECT AREA: Metallurgy[br]b. c. 23 AD Como, Italyd. 25 August 79 AD near Pompeii, Italy[br]Roman encyclopedic writer on the natural world.[br]Pliny was well educated in Rome, and for ten years or so followed a military career with which he was able to combine literary work, writing especially on historical subjects. He completed his duties c. 57 AD and concentrated on writing until he resumed his official career in 69 AD with administrative duties. During this last phase he began work on his only extant work, the thirty-seven "books" of his Historia Naturalis (Natural History), each dealing with a broad subject such as astronomy, geography, mineralogy, etc. His last post was the command of the fleet based at Misenum, which came to an end when he sailed too near Vesuvius during the eruption that engulfed Pompeii and he was overcome by the fumes.Pliny developed an insatiable curiosity about the natural world. Unlike the Greeks, the Romans made few original contributions to scientific thought and observation, but some made careful compilations of the learning and observations of Greek scholars. The most notable and influential of these was the Historia Naturalis. To the ideas about the natural world gleaned from earlier Greek authors, he added information about natural history, mineral resources, crafts and some technological processes, such as the extraction of metals from their ores, reported to him from the corners of the Empire. He added a few observations of his own, noted during travels on his official duties. Not all the reports were reliable, and the work often presents a tangled web of fact and fable. Gibbon described it as an immense register in which the author has "deposited the discoveries, the arts, and the errors of mankind". Pliny was indefatigable in his relentless note-taking, even dictating to his secretary while dining.During the Dark Ages and early Middle Ages in Western Europe, Pliny's Historia Naturalis was the largest known collection of facts about the natural world and was drawn upon freely by a succession of later writers. Its influence survived the influx into Western Europe, from the twelfth century, of translations of the works of Greek and Arab scholars. After the invention of printing in the middle of the fifteenth century, Pliny was the first work on a scientific subject to be printed, in 1469. Many editions followed and it may still be consulted with profit for its insights into technical knowledge and practice in the ancient world.[br]BibliographyThe standard Latin text with English translation is that edited by H.Rackham et al.(1942– 63, Loeb Classical Library, London: Heinemann, 10 vols). The French version is by A.Further ReadingThe editions mentioned above include useful biographical and other details. For special aspects of Pliny, see K.C.Bailey, 1929–32, The Elder Pliny's Chapters on Chemical Subjects, London, 2 vols.LRDBiographical history of technology > Pliny the Elder (Gaius Plinius Secundus)
