Racial residential segregation patterns in the eight largest Ohio cities are examined from 1950-1980 to determine if certain gains which blacks recently have made in other areas of life have been translated into improved residential integration. Data were collected from the 1950, I960, 1970, and 1980 United States Censuses of Population and Housing at the census tract level. The index of dissim...

We investigate at the subscale of the neighborhoods of a highly populated city the incidence of property crimes in terms of both the resident and the floating population. Our results show that a relevant allometric relation could only be observed between property crimes and floating population. More precisely, the evidence of a superlinear behavior indicates that a disproportional number of pro...

Of 126 homosexual men in a selected population in New York City, 31.7% were infected with Entamoeba histolytica, 18.3% with Giardia lamblia, and 39.7% with one or both on a single stool examination. Of 5885 clinic and hospital patients examined in the same laboratory by the same methods, 1.3% were infected with E. histolytica, 2.1% with G. lamblia, and 3.3% with one or both. Evidence indicates ...

IntroductionThe turnover rate of care workers has remained high by global standards, with previous studies showing an association between workplace interpersonal relations and worker intentions. This study details the development Workplace Interpersonal Problems Scale for Care Workers (WIPS) examines its reliability validity according to COSMIN guidelines.MethodsA total 476 employed elder facil...

INTRODUCTION At the East part of DRC, anecdotal reports are advancing several causes of unsuccessful campaigns of vaccination by the time going: rumors about use of vaccines for killing purpose, injection of vaccine to decrease the reproductive potential in coming generations, use of vaccines by some rebellions and neighboring countries to kill children indirectly, ineffectiveness of vaccines c...

The increasing population and economic activities are putting pressure on the available land resources. Human population and their use of land have transformed the terrestrial biosphere into anthropogenic biomes (anthromes). The present study analyses the urban land use/cover change and land transformation in Srinagar city which is located in the valley of the hill state of Jammu and Kashmir. A...

BACKGROUND The shortage of physicians is reported in the small cities in Japan, but the mal-distribution of physicians and emergency medical facilities has not been fully investigated. METHODS Survey of Medical Institutions, 2005, Survey of Physicians, Dentists and Pharmacists, 2004, and 2005 Population Census of Japan were used. The relationships between city population and the numbers of me...

In this paper, we study social interactions between two populations of individuals living in a city. Agents consume land and benefit from intraand inter-group social interactions. We show that in equilibrium segregation arises: populations get separated in distinct spatial neighborhoods. Twoand three-district urban structures are characterized. For high population ratios or strong intergroup in...

The method of spectral analysis is employed to research the spatial dynamics of urban population distribution. First of all, the negative exponential model is derived in a new way by using an entropy-maximizing idea. Then an approximate scaling relation between wave number and spectral density is derived by Fourier transform of the negative exponential model. The theoretical results suggest the...
