It is generally agreed that the first true cities appeared about 5,000 years ago in the food-producing communities of the Middle East. The cities of Sumeria, Egypt and the Indus Valley possessed a number of characteristics that distinguished them as truly urban. The cities were very much larger and more densely populated than any previous settlement, and their function was clearly differentiated from that of the surrounding villages. In the cities the old patterns of kinship relations were replaced by a complex hierarchy of social classes based on the specialization of labor. Moreover, the need to keep records led to the development of writing and arithmetic, and the increased sophistication of urban society gave a new impetus to artistic expression of every kind.
When the basis of city life was established in Europe the urban tradition was drawn from the ancient cities of the Middle East, via the civilization of Greece and Rome. We can trace three main phases in the growth of the West European city. The first of these is the medieval phase, which extends from the beginning of the 1lth century A. D. to about 1,500. The second is the renaissance and Baroque phase, which can be traced from about 1,500 to the beginning of the 19th century. The third is the modern phase extending from the early 19th century to the present day.
Every medieval city began as a small settlement, which grew up round a geographical or cultural focal point. This would be a permanent structure such as a stronghold, a cathedral or a large church. In districts where travel and trade were well established, it might be a market, a river crossing, or a place where two or more trade routes met. In studies of urban geography the oldest part of town is referred to as the nuclear settlement. There are many small towns in Europe where it is still possible to trace the outline of the original nuclear settlement. It is, of course, much more difficult to do this in the case of a large modern city which has grown to many times its original size.
The ancient cities were characterized by all the following except ______.
No longer. The Internet and pressure from funding agencies, who are questioning why commercial publishers are making money from government-funded research by restricting access to it--is making access to scientific results a reality. The organization for Economic Cooperation and Development (OECD) has just issued a report describing the far-reaching consequences of this. The report, by John Houghton of Victoria University in Australia and Graham Vickery of the OECD, makes heavy reading for publishers who have, so far, made handsome profits. But it goes further than that. It signals a change in what has, until now, been a key element of scientific endeavor.
The value of knowledge and the return on the public investment in research depends, in part, upon wide distribution and ready access. It is big business. In America, the core scientific publishing market is estimated at between $ 7 billion and $ 11 billion. The International Association of Scientific, Technical and Medical Publishers says that there are more than 2, 000 publishers worldwide specializing in these subjects. They publish more than 1.2 million articles each year in some 16, 000 journals.
This is now changing. According to the OECD report, some 75% of scholarly journals are now online. Entirely new business models are emerging; three main institutional subscribers pay for access to a collection of online journal rifles through site-licensing agreements. There is open-access publishing, typically supported by asking the author (or his employer) to pay for the paper to be published. Finally, there are open-access archives, where organizations such as universities or international laboratories support institutional repositories. Other models exist that are hybrids of these three, such as delayed open-access, where journals allow only subscribers to read a paper for the first six months, before making it freely available to everyone who wishes to see it. All this could change the traditional form. of the peer-review process, at least for the publication of papers.
