The numerical and qualitative aspects of the growth of the Indians urban population are discussed with the benefit of data from the last 4 censuses. Thinkers exemplified by M.K. Gandhi believe that urban growth erodes Indian culture, while opponents argue that India's traditional way of life deserves to be obliterated. The "mechanics" of erosion of Indian culture is discussed under 5 headings: its locus, speed, direction, type of population shifts, and types of cities affected by growth. The village, which is the principal locus of Indian culture, is the locus affected by urbanization. The quantitative estimate of urbanization is extremely rapid: between 1951 and 1988, the urban population grew from 62 to 217 million. In this period rural numbers grew from 295 to 618 million. Because of the hugh natural increase of the rural population, the proportion of the urban population grew only from 17.3% to 23.3%. The direction of change is described as a process or cultural accretion or "interpenetration" rather than replacement of tradition by urban culture. Populations shifts account for a large amount of urban increase, a net rise in urban sector of 15 million/decade. While the 4 largest cities received the most immigrants, growing at 3.16%, the intermediate 6 cities with populations 1 million in 1981 grew even faster, at 3.48%. It is likely that India's population after the 1991 census is complete will be 910 million, with 27% urban.  相似文献

This paper provides a brief biography of Luke S. May (1886-1965), whose pioneering work in forensic science in the United States has not received full recognition. May began as a private detective in Salt Lake City, Utah, shortly after the turn of the century and later established his own agency, the Revelare International Secret Service, which he moved to Seattle, Washington, in 1919. Although basically self-taught in scientific matters, May built a solid reputation among police agencies and attorneys in the Pacific Northwest and Western Canada as a serious and effective scientific investigator in the era before public crime laboratories. This reputation as "America's Sherlock Holmes" also led to his being consulted on the establishment of the first American crime laboratory at Northwestern University in Chicago, Illinois, and on a laboratory for the Royal Canadian Mounted Police at Regina, in Saskatchewan, Canada. He contributed to a landmark case of court acceptance of toolmark identification, invented specialized instruments, and founded an institute to teach scientific criminal investigation to police officers. His earliest associates were John L. Harris and J. Clark Sellers, both of whom became recognized document examiners on the West Coast and were followed by a second and a third generation of practitioners.  相似文献
