Estimating the size and distribution of South Asian religious populations in Britain: is there an alternative to a religion question in the census?     

Brown MS 《International journal of population geography : IJPG》2000,6(2):87-109

This paper addresses the question of whether there is an alternative to asking a direct religious question in the 2001 Census through a systematic review of alternative methods of quantifying religious populations. After establishing the limited availability of direct information on religion, the paper considers the application of an inferential method for estimating religious populations based on data from the 1994 Fourth National Survey of Ethnic Minorities (NSEM). Except for the monoreligious Pakistani and Bangladeshi populations, evidence of substantial spatial variation in the association between ethnicity and religion severely limits application of the method below national level. Using the religiously diverse Indian population of outer London as a case study, the NSEM is investigated to see whether the incorporation of other ?predictors? of religion as weighting variables improves sensitivity of the method to this variation. In a second method, logistic regression is employed to develop predictive models of religious affiliation for application to census microdata. Based on these two applications, it was concluded that very little of the variation in the religious geography of Indians in outer London can be inferred from measured characteristics in the census. However, this does not necessarily imply support for inclusion of a religion question in the 2001 Census. It was suggested that it may be more appropriate and cost effective to define and solve the need for data locally.  相似文献   

Far-Ultraviolet Emission from Elliptical Galaxies at z = 0.55     

Brown TM  Bowers CW  Kimble RA  Ferguson HC 《The Astrophysical journal》2000,529(2):L89-L93

The rest-frame UV-to-optical flux ratio, which characterizes the "UV upturn" phenomenon, is potentially the most sensitive tracer of age in elliptical galaxies; models predict that it may change by orders of magnitude over the course of a few gigayears. In order to trace the evolution of the UV upturn as a function of redshift, we have used the far-UV camera on the Space Telescope Imaging Spectrograph to image the galaxy cluster CL 0016+16 at z=0.55. Our 25"x25" field includes four bright elliptical galaxies, spectroscopically confirmed to be passively evolving cluster members. The weak UV emission from the galaxies in our image demonstrates that the UV upturn is weaker at a look-back time approximately 5.6 Gyr earlier than our own, as compared to measurements of the UV upturn in cluster E and S0 galaxies at z=0 and z=0.375. These images are the first with sufficient depth to demonstrate the fading of the UV upturn expected at moderate redshifts. We discuss these observations and the implications for the formation history of galaxies.  相似文献   

A possible lower crustal flow channel in the Middle Urals based on reflection seismic data   总被引：1，自引：0，他引：1  

D. Brown  C. Juhlin 《地学学报》2006,18(1):1-8

The Europrobe Seismic Reflection Profiling in the Urals Experiments (ESRU) reflection seismic data from the Middle Urals images c. 10‐km thick band of strong, subhorizontal lower crustal reflectivity and a thinning of the crust that is associated with the East Uralian Zone, a broad strike‐slip fault system containing high‐grade metamorphic rocks and syn‐orogenic to post‐orogenic granitoids. The lower crustal reflectivity consists of discontinuous to continuous, high‐amplitude reflections. Reflections are subparallel to slightly oblique and have a layered to oblate appearance. Geometrical relationships indicate that the reflectivity post‐dates fault activity, suggesting that late‐orogenic processes modified the lower crust. The surface geology indicates that the conditions for lower crustal flow were met in the East Uralian Zone. We suggest that the lower crustal reflectivity imaged by the ESRU data is related to a flow channel that developed at the base of the crust in the interior of the orogen.  相似文献   

Immigrant Profiles of U.S. Urban Areas and Agents of Resettlement*     

Lawrence A. Brown  Tamar E. Mott  Edward J. Malecki 《The Professional geographer》2007,59(1):56-73

This article targets the role of intermediaries, such as refugee resettlement programs, in altering the geography of the foreign‐born. It argues that, under such intermediaries, destination choice within the United States is largely determined not by economic mechanisms but instead by information‐related factors such as friction of distance, migration chains, labor procurement, and resettlement intermediaries. Metropolitan statistical area (MSA) destinations are grouped into four profiles based on their mix of foreign‐born. The result is sets of MSAs differentiated by the era of immigration, immigrant origins, geographic pattern, and place characteristics that draw migrants. To evaluate intermediary impacts, monies allocated to states by the Office of Refugee Resettlement, refugee resettlement by state, and refugee movements to MSAs are expressed as a Refugee Resettlement Index and linked to MSA profiles. We conclude that although refugees constitute only a portion of total immigration, their effects are disproportionately large in terms of changing the foreign‐born profiles of MSAs and other communities, changing the fabric of society, and changing the geography of the foreign‐born in all its ramifications.  相似文献

Littoral fish assemblages of the alien-dominated Sacramento-San Joaquin Delta,California, 1980–1983 and 2001–2003     

Larry R. Brown  Dennis Michniuk 《Estuaries and Coasts》2007,30(1):186-200

We analyzed monthly boat electrofishing data to characterize the littoral fish assemblages of five regions of the Sacramento-San Joaquin Delta (northern, southern, eastern, western, and central), California, during two sampling periods, 1980–1983 (1980s) and 2001–2003 (2000s), to provide information pertinent to the restoration of fish populations in this highly altered estuary. During the 1980s, almost 11,000 fish were captured, including 13 native species and 24 alien species. During the 2000s, just over 39,000 fish were captured, including 15 native species and 24 alien species. Catch per unit effort (CPUE) of total fish, alien fish, and centrarchid fish were greater in the 2000s compared with the 1980s, largely because of increased centrarchid fish CPUE. These differences in CPUE were associated with the spread of submerged aquatic vegetation (SAV), particularly an alien aquatic macrophyte,Egeria densa. Native fish CPUE declined from the 1980s to the 2000s, but there was no single factor that could explain the decline. Native fish were most abundant in the northern region during both sampling periods. Nonmetric multidimensional scaling indicated similar patterns of fish assemblage composition during the two sampling periods, with the northern and western regions characterized by the presence of native species. The separation of the northern and western regions from the other regions was most distinct in the 2000s. Our results suggest that native fish restoration efforts will be most successful in the northern portion of the Delta. Management decisions on the Delta should include consideration of possible effects on SAV in littoral habitats and the associated fish assemblages and ecological processes.  相似文献
